Search for Antideuterons of Cosmic Origin Using the BESS-Polar II Magnetic-Rigidity Spectrometer. PHYSICAL REVIEW LETTERS 2024; 132:131001. [PMID: 38613296 DOI: 10.1103/physrevlett.132.131001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 10/21/2023] [Accepted: 01/10/2024] [Indexed: 04/14/2024]
Abstract
We searched for antideuterons (d[over ¯]'s) in the 4.7×10^{9} cosmic-ray events observed during the BESS-Polar II flight at solar minimum in 2007-2008 but found no candidates. The resulting 95% C.L. upper limit on the d[over ¯] flux is 6.7×10^{-5} (m^{2} s sr GeV/n)^{-1} in an energy range from 0.163 to 1.100 GeV/n. The result has improved by more than a factor of 14 from the upper limit of BESS97, which had a potential comparable to that of BESS-Polar II in the search for cosmic-origin d[over ¯]'s and was conducted during the former solar minimum. The upper limit of d[over ¯] flux from BESS-Polar II is the first result achieving the sensitivity to constrain the latest theoretical predictions.

Characterization of a half-wave plate for cosmic microwave background circular polarization measurement with POLARBEAR. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2023; 94:064502. [PMID: 37862532 DOI: 10.1063/5.0140088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Accepted: 06/03/2023] [Indexed: 10/22/2023]
Abstract
A half-wave plate (HWP) is often used as a modulator to suppress systematic error in the measurements of cosmic microwave background (CMB) polarization. A HWP can also be used to measure circular polarization (CP) through its optical leakage from CP to linear polarization. The CP of the CMB is predicted from various sources, such as interactions in the Universe and extension of the standard model. Interaction with supernova remnants of population III stars is one of the brightest CP sources. Thus, the observation of the CP of CMB is a new tool for searching for population III stars. In this paper, we demonstrate the improved measurement of the leakage coefficient using the transmission measurement of an actual HWP in the laboratory. We measured the transmittance of linearly polarized light through the HWP used in Polarbear in the frequency range of 120-160 GHz. We evaluate the properties of the HWP by fitting the data with a physical model using the Markov Chain Monte Carlo method. We then estimate the band-averaged CP leakage coefficient using the physical model. We find that the leakage coefficient strongly depends on the spectra of CP sources. We thus calculate the maximum fractional leakage coefficient from CP to linear polarization as 0.133 ± 0.009 in the Rayleigh-Jeans spectrum. The nonzero value shows that Polarbear has a sensitivity to CP. Additionally, because we use the bandpass of detectors installed in the telescope to calculate the band-averaged values, we also consider systematic effects in the experiment.

Abstract
A 3-month-old Shetland sheepdog presented with a loud ejection murmur and exercise intolerance. Echocardiography revealed an accessory mitral valve leaflet, characterised by a valve-like structure separate from the mitral valve seen in the subaortic region of the ventricular septum. The left ventricular outflow tract was partially obstructed with a pressure gradient of 12 mmHg. Accessory mitral valve leaflet resection and mitral valvuloplasty were performed during open-heart surgery. Histology performed on the membrane-like structures were indicative of fibrous connective tissues. Postoperative echocardiography confirmed removal of the valve-like structure with resolution of the left ventricular outflow tract obstruction. The pressure gradient was decreased to 4.6 mmHg. The dog was in good condition and no further treatment was required 5 months after surgery. Both cardiac troponin I and NT-proBNP were markedly decreased. In this dog, surgical resection combined with mitral valve plasty resolved the left ventricular outflow tract obstruction and the clinical signs.

Abstract
BACKGROUND Pacific islanders face drastic increase of obesity-related noncommunicable disease (NCD) due to lifestyle shifts of unhealthy diets and physical inactivity. To date, however, obesity related factors have not been well elucidated in Republic of Palau. This study aimed to investigate sociodemographic and behavioral factors related to obesity using the national level data in Palau. METHODS This is a cross-sectional, population-based study analyzing random sampling data of 2133 adults aged 25-64 years (of 20 thousand national population) from the WHO STEPwise approach to NCD risk factor surveillance (STEPS) implemented between 2011 and 2013. Sociodemographic and behavioral factors were obtained by the STEPS standardized questionnaire for NCD risk factors plus the question on betel nut chewing because of its common behavior in Micronesian countries. Logistic regression analysis was performed to estimate multivariable odds ratio (OR) of general obesity (body mass index ≥30.0 kg/m2) and central obesity (waist circumference ≥90 cm in men and ≥80 cm in women). RESULTS Means of body mass index, prevalence of general obesity and central obesity were higher in women (29.9 kg/m2, 45.5% and 85.4%) than in men (29.3 kg/m2, 40.4% and 67.6%). After adjusted by other potential factors, native Palauan (OR 4.4, 95% CI, 2.7-7.0 for men and 3.6, 2.3-5.6 for women), betel nut chewing (1.5, 1.1-2.1 for men and 1.6, 1.2-2.3 for women), men who work at government office (1.6, 1.2-2.1), women with higher household income (1.4, 1.0-1.8) were positively associated with general obesity, while frequent vegetable intake were inversely associated with it among women (0.71, 0.54-0.93). Similar associations were observed between the aforementioned factors and central obesity. CONCLUSIONS Native Palauan, people with betel nut chewing behavior, government employment and higher income appeared to be associated with obesity, while frequent vegetable consumption were inversely associated with obesity. Further interventions for prevention and control of obesity are necessary through the enhancing public relation activities to understand harmful health effects on betel nuts chewing and recommending domestic production of vegetables.

Conceptual design of a heavy ion beam probe for the QUEST spherical tokamak. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2022; 93:113516. [PMID: 36461548 DOI: 10.1063/5.0101770] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 08/11/2022] [Indexed: 06/17/2023]
Abstract
A heavy ion beam probe (HIBP) has been designed for the QUEST spherical tokamak to measure plasma turbulence and the profiles of electric potential profiles. Using a cesium ion beam with an energy of several 10 keV, the observable region covers most of the upper half of the plasma. Although the probe beam is deflected by the poloidal magnetic field produced by plasma current and poloidal coil currents, it can be detected under plasma current up to 150 kA by modifying the trajectories with two electrostatic sweepers. According to the numerical estimation of the intensity of the detected beam, sufficient signal intensity for measuring plasma turbulence can be obtained over almost the measurable area when the electron density is up to 1 × 1019 m-3, which is larger than the cut-off density of electron cyclotron heating in QUEST. The performance of the designed HIBP is sufficient to explore the mechanisms of heat and particle transport in magnetically confined plasmas, including the influence of plasma wall interactions, which is a goal of the QUEST project.

Abstract
Abstract
Study question
Is specific microbiota in the endometrial fluid (EF) associated with pregnancy outcome in a frozen embryo transfer (FET) cycles?
Summary answer
Lactobacillus had high abundance in the microbiota of endometrial fluid of patients with successful pregnancy after FET treatment.
What is known already
Recently, the relationship between endometrial microbiota and repeated implantation failure (RIF) has been reported. While Lactobacillus-dominated microbiota (LDM, defined as > = 90 % Lactobacillus species) in the EF of the receptive phase was reported to be associated with favorable reproductive outcome, non-LDM (< 90 % Lactobacillus species) was found to decrease implantation, clinical pregnancy, ongoing pregnancy, and live birth rates. However, it is still unclear the effect of the microbiota on pregnancy outcome of the patients with the assisted reproductive technology, especially a frozen embryo transfer (FET) treatment.
Study design, size, duration
We included 802 cycles with clinical results of pregnancy outcome after FET treatment at our clinic from December 2018 to January 2021. Endometrium fluid was collected before FET and microbiota was examined. We examined the relationship between endometrial microbiota and pregnancy outcome in 463 cycles in which the endometrial microbiome test results were available, pregnancy outcome was known, CD138 negative, and less than 38years (229 cycles were positive pregnancy and 234 cycles were negative pregnancy).
Participants/materials, setting, methods
Sampling was performed carefully avoiding contamination before FET treatment. Extracted genomic DNA was sequenced for the region of 16S ribosomal RNA using next-generation sequencer (Endometrial microbiome test, Varinos, Japan). The sequencing data was assigned to bacterial taxonomy and the background-contaminated bacteria were excluded from the microbiome profile. Lactobacillus abundance was calculated. After concordance of patient background, Lactobacillus abundance between successful and unsuccessful pregnancy group was compared.
Main results and the role of chance
We investigated the effect of microbiota in EF, especially Lactobacillus, for the infertile female with frozen embryo transfer (FET) as an assisted reproductive treatment with large amount of cycles (802 cycles). First, all of cycles were divided into a successful pregnancy group (305/802) and an unsuccessful pregnant group (497/802), and then the abundance of Lactobacillus was analyzed (the pregnancy ratio was 38.0%). The mean abundance of Lactobacillus in EF was significantly higher in the successful pregnant group than in the unsuccessful pregnant group (70.2% 40.5 versus 63.5% 43.1, p = 0.007). To further refine the conditions of each cycle, patient backgrounds of each cycle were compared. There was a significant difference in age and CD138 results between the successful pregnant group and unsuccessful pregnant group, so the analysis was performed with the limited cycles with CD138-negative and under 38 years (229/463 versus 234/463, respectively). However, even under this strict condition, the mean abundance of Lactobacillus was significantly higher in the pregnant group than in the unsuccessful pregnant group (72.1% 39.7 versus 61.1% 44.4, p = 0.003). These results suggest that the endometrial environment with high Lactobacillus abundance is more conducive to pregnancy in FET treatment.
Limitations, reasons for caution
The limitation of this study is that the design is not a randomized controlled one, although it is prospective.
Wider implications of the findings
The results of this study suggest that the endometrial microbiota at the time of embryo implantation, especially Lactobacillus genus, is highly relevant to pregnancy outcome, implying that disruption of the intrauterine microbiota may cause infertility. We need further studies to improve the endometrial microbiota of infertile women.

Abstract
BackgroundGenome-wide association studies (GWASs) have identified 29 disease-associated single nucleotide polymorphisms (SNPs) for systemic sclerosis (SSc) in non-human leukocyte antigen (HLA) regions (1-7). While these GWASs have clarified genetic architectures of SSc, study subjects were mainly Caucasians limiting application of the findings to Asians.ObjectivesThe study was conducted to identify novel causal variants for SSc specific to Japanese subjects as well as those shared with European population. We also aimed to clarify mechanistic effects of the variants on pathogenesis of SSc.MethodsA total of 114,108 subjects comprising 1,499 cases and 112,609 controls were enrolled in the two-staged study leading to the ever-largest Asian GWAS for SSc. After applying a strict quality control both for genotype and samples, imputation was conducted using the reference panel of the phase 3v5 1,000 genome project data combined with a high-depth whole-genome sequence data of 3,256 Japanese subjects. We conducted logistic regression analyses and also combined the Japanese GWAS results with those of Europeans (6) by an inverse-variance fixed-effect model. Polygenicity and enrichment of functional annotations were evaluated by linkage disequilibrium score regression (LDSC), Haploreg and IMPACT programs. We also constructed polygenic risk score (PRS) to predict SSc development.ResultsWe identified three (FCRLA-FCGR, TNFAIP3, PLD4) and four (EOMES, ESR1, SLC12A5, TPI1P2) novel loci in Japanese GWAS and a trans-population meta-analysis, respectively. One of Japanese novel risk SNPs, rs6697139, located within FCGR gene clusters had a strong effect size (OR 2.05, P=4.9×10-11). We also found the complete LD variant, rs10917688, was positioned in cis-regulatory element and binding motif for an immunomodulatory transcription factor IRF8 in B cells, another genome-wide significant locus in our trans-ethnic meta-analysis and the previous European GWAS. Notably, the association of risk allele of rs10917688 was significant only in the presence of the risk allele of the IRF8. Intriguingly, rs10917688 was annotated as one enhancer-related histone marks, H3K4me1, in B cells, implying that FCGR gene(s) in B cells may play an important role in the pathogenesis of SSc. Furhtermore, significant heritability enrichment of active histone marks and a transcription factor C-Myc were found in B cells both in European and Japanese populations by LDSC and IMPACT, highlighting a possibility of a shared disease mechanism where abnormal B-cell activation may be one of the key drivers for the disease development. Finally, PRS using effects sizes of European GWAS moderately fit in the development of Japanese SSc (AUC 0.593), paving a path to personalized medicine for SSc.ConclusionOur study identified seven novel susceptibility loci in SSc. Downstream analyses highlighted a novel disease mechanism of SSc where an interactive role of FCGR gene(s) and IRF8 may accelerate the disease development and B cells may play a key role on the pathogenesis of SSc.References[1]F.

Abstract
Objective Cost-benefit is an important consideration for Helicobacter pylori (H. pylori) eradication in Japan, where 1.5 million patients were reported to receive first-line eradication annually. This study aimed to identify the optimal cost-saving triple therapy regimen for H. pylori eradication in Japan. Materials and Methods This retrospective observational study used data from a large-scale, nationwide health insurance claims database (2015‒2018). Using success rates of first-line eradication, mean total costs of first-line and second-line eradications per patient were compared between regimens including a potassium-competitive acid blocker (P-CAB) or a proton pump inhibitor (PPI), and between two clarithromycin (CAM) doses (400 and 800 mg/day). Subgroup analyses by smoking habit or body mass index (BMI) were performed. Results Among propensity score (age, gender, CAM dose, disease name)-matched patients (P-CAB regimen, n=22,002; PPI regimen, n=22,002), total costs were lower with the P-CAB than the PPI regimen (Japanese yen [JPY] 12,952 vs 13,146) owing to significantly higher first-line eradication rates with the P-CAB regimen (93.6% vs 79.7%; p<0.001). For both regimens, even among current smokers or patients with BMI ≥25 kg/m2, eradication rates did not differ by CAM dose, and total costs were approximately JPY1000 lower with CAM 400 mg/day than with CAM 800 mg/day. Conclusion High success rate of first-line eradication contributes to saving in total eradication costs by reducing costs of subsequent therapy, irrespective of patients' smoking status or BMI class. The combination of more potent acid-inhibitory medicine and low-dose CAM may be the optimal regimen in terms of efficacy and cost-benefit in Japan.

Abstract
Using only cosmic microwave background polarization data from the polarbear experiment, we measure B-mode polarization delensing on subdegree scales at more than 5σ significance. We achieve a 14% B-mode power variance reduction, the highest to date for internal delensing, and improve this result to 22% by applying for the first time an iterative maximum a posteriori delensing method. Our analysis demonstrates the capability of internal delensing as a means of improving constraints on inflationary models, paving the way for the optimal analysis of next-generation primordial B-mode experiments.

Abstract
The macrocyclic ligand calix[4]arene (L1) and its sulphur-containing analogue thia[4]calixarene (L2) are promising precursors for functional molecular materials as they offer rational functionalization with various organic groups. Here, we present the first example of lanthanide-based coordination polymers built from the macrocyclic thiacalix[4]arene backbone bearing four carboxylic moieties, namely, ligand H4L3. The combination of H4L3 with the Tb3+ and Dy3+ cations led to the formation of 1D ladder-type coordination polymers with the formula [LnIIIHL3DMF3]·(DMF) (where DMF = dimethylformamide and Ln = Tb or Dy, denoted as HL3–Tb and HL3–Dy), which resulted from the coordination of the lanthanide cations with the partially deprotonated ligand HL33− that behaved as a T-shape connector. The coordination sphere around the metal was completed by the coordinated DMF solvent molecules. By combining both Tb3+ and Dy3+ cations, isostructural heterobimetallic solid solutions HL3–Tb1−xDyx were also prepared. HL3–Tb and HL3–Dy showed visible light photoluminescence originating from the f–f electronic transitions of pale green emissive Tb3+ and pale yellow emissive Dy3+ with efficient sensitization by the functionalized thia[4]calixarene ligand HL3. In the HL3–Tb1−xDyx solid solutions, the Tb/Dy ratio governed both the emission colour as well as the emission quantum yield, which reached even 28% at room temperature for HL3–Tb. Moreover, HL3–Dy exhibited a slow magnetic relaxation effect related to the magnetic anisotropy of the dodecahedral Dy3+ complexes, which were well isolated in the crystal lattice by expanded organic spacers. The single crystals of the two isostructural Tb3+- and Dy3+-based coordination polymers (HL3–Tb and HL3–Dy) were structurally characterized, and their photophysical properties were investigated, together with their corresponding solid solutions.![]()

Five-year cumulative incidence of overweight and obesity, and longitudinal change in body mass index in Japanese workers: The Japan Epidemiology Collaboration on Occupational Health Study. J Occup Health 2020; 62:e12095.

Abstract
OBJECTIVE The present study aimed to estimate cumulative incidence of overweight and obesity and describe 5-year longitudinal changes in body mass index (BMI) in a large occupational cohort in Japan. METHODS Participants were 55 229 Japanese employees, who were aged 20-59 years and attended at all subsequent annual health check-ups between 2009 and 2014. Mixed model analysis was performed to examine the effects of age and cohort by gender on BMI change, with age as a random variable. Cumulative incidence of overweight (23.0≤ BMI <27.5 kg/m2 ) and obesity (BMI ≥27.5 kg/m2 ) was calculated. Logistic regression analysis was used to estimate odds ratios for the incidence of overweight and obesity according to age group. RESULTS The incidence of overweight and obesity was approximately double in men (28.3% and 6.7%, respectively) compared to women (14.3% and 3.9%, respectively).The incidence of obesity decreased with age in men, but did not differ according to age in women (P for trend: .02 and .89, respectively). Among overweight participants, the incidence of obesity was higher in women (18.9%) than men (14.5%) and decreased with advancing age (P for trend: <.001 in men and .003 in women). Mean BMI was higher in men than women in all age groups throughout the period. Younger cohorts tended to have a higher BMI change compared with older cohorts. CONCLUSIONS In this Japanese occupational cohort, transition from overweight to obesity is higher in women than men, and the more recent cohorts had a higher change in mean BMI than the older cohorts.

The POLARBEAR Fourier transform spectrometer calibrator and spectroscopic characterization of the POLARBEAR instrument. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2019; 90:115115. [PMID: 31779409 DOI: 10.1063/1.5095160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2019] [Accepted: 11/01/2019] [Indexed: 06/10/2023]
Abstract
We describe the Fourier Transform Spectrometer (FTS) used for in-field testing of the POLARBEAR receiver, an experiment located in the Atacama Desert of Chile which measures the cosmic microwave background (CMB) polarization. The POLARBEAR-FTS (PB-FTS) is a Martin-Puplett interferometer designed to couple to the Huan Tran Telescope (HTT) on which the POLARBEAR receiver is installed. The PB-FTS measured the spectral response of the POLARBEAR receiver with signal-to-noise ratio >20 for ∼69% of the focal plane detectors due to three features: a high throughput of 15.1 sr cm2, optimized optical coupling to the POLARBEAR optics using a custom designed output parabolic mirror, and a continuously modulated output polarizer. The PB-FTS parabolic mirror is designed to mimic the shape of the 2.5 m-diameter HTT primary reflector, which allows for optimum optical coupling to the POLARBEAR receiver, reducing aberrations and systematics. One polarizing grid is placed at the output of the PB-FTS and modulated via continuous rotation. This modulation allows for decomposition of the signal into different harmonics that can be used to probe potentially pernicious sources of systematic error in a polarization-sensitive instrument. The high throughput and continuous output polarizer modulation features are unique compared to other FTS calibrators used in the CMB field. In-field characterization of the POLARBEAR receiver was accomplished using the PB-FTS in April 2014. We discuss the design, construction, and operation of the PB-FTS and present the spectral characterization of the POLARBEAR receiver. We introduce future applications for the PB-FTS in the next-generation CMB experiment, the Simons Array.

Abstract
Social insects face strong selection from parasites because the conditions of group living often favor the transmission of infection among nestmates. However, there is little detailed information on the effects of parasite infection in the host species. Workers of Polybia species, neotropical swarm-founding wasps, are commonly infected by gregarines, protozoans that are exclusively parasitic on invertebrates. Previous studies showed that high rates of gregarine infection in workers of Polybia occidentalis (Olivier) have negative effects on their colony performance. However, the effect of seasonality on infection rates throughout the year or between wet and dry seasons has not been examined. Host-parasite interactions cannot be understood without consideration of the overall population dynamic. We compared rates of gregarine infection in workers of Polybia paulista (Ihering) between wet and dry seasons and among months. The 35% rate was by far the highest of the four wet seasons sampled, but the rates declined in the mid-wet season and were very low during the dry season. Strong seasonal differences in infection rates were also observed between the dry and wet seasons. Several potential factors affecting the seasonal differences are discussed.

Vegetative growth after flowering through gibberellin biosynthesis regulates pod setting rate in soybean (Glycine max (L.) Merr.). PLANT SIGNALING & BEHAVIOR 2018; 13:e1473668.

Abstract
Pod setting rate in soybean is an important trait that determines pod number, which is highly correlated with seed yield. Using two soybean cultivars with different pod setting rates, we examined the relationship between plant growth regulation by gibberellin (GA) and pod setting rate. Plant growth rate (PGR) after flowering was significantly higher in 'Fukuyutaka' (low pod setting rate) than in 'Kariyutaka' (high pod setting rate); this difference was caused by increasing of GA biosynthesis-related genes expression. Additionally, pod setting rate in 'Fukuyutaka' was lower than that in 'Kariyutaka'. Furthermore, when 'Kariyutaka' was treated with GA after flowering, the PGR increased and pod setting rate decreased. These results suggest that pod setting rate in soybean is regulated by vegetative growth after flowering through GA biosynthesis.

Abstract
A search for boosted dark matter using 161.9 kt yr of Super-Kamiokande IV data is presented. We search for an excess of elastically scattered electrons above the atmospheric neutrino background, with a visible energy between 100 MeV and 1 TeV, pointing back to the Galactic center or the Sun. No such excess is observed. Limits on boosted dark matter event rates in multiple angular cones around the Galactic center and Sun are calculated. Limits are also calculated for a baseline model of boosted dark matter produced from cold dark matter annihilation or decay. This is the first experimental search for boosted dark matter from the Galactic center or the Sun interacting in a terrestrial detector.

Abstract
The results of a search for new heavy W ' bosons decaying to an electron or muon and a neutrino using proton-proton collision data at a centre-of-mass energy ofs = 13 TeV are presented. The dataset was collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1 fb - 1 . As no excess of events above the Standard Model prediction is observed, the results are used to set upper limits on the W ' boson cross-section times branching ratio to an electron or muon and a neutrino as a function of the W ' mass. Assuming a W ' boson with the same couplings as the Standard Model W boson, W ' masses below 5.1 TeV are excluded at the 95% confidence level.

Unusual Case of Vogt-Koyanagi-Harada Disease Associated with SAPHO Syndrome: A Case Report. Case Rep Ophthalmol 2018; 9:202-208.

Abstract
A 66-year-old Japanese woman who was diagnosed with synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome presented with bilateral blurred vision 4 months prior to visiting our hospital. She had visited a local ophthalmology clinic first. She was diagnosed with conjunctivitis and was prescribed antibacterial eye drops. The symptoms persisted in spite of treatment. She was then referred to our hospital. At her initial visit, the visual acuities were 0.6 in both eyes. A slit-lamp examination revealed bilateral shallow anterior chamber, and intraocular pressures of 18 mm Hg in the right eye and 16 mm Hg in the left eye. There were no cells in the anterior chamber. Fundus examination revealed bilateral annular choroidal detachment and serous retinal detachment. Fluorescein angiography showed leakage of dye from the retinal pigment epithelium (RPE) and indocyanine green angiography showed focal choroidal hypoperfusion. Optical coherence tomography showed wavy RPE line and blurry thick choroid. Systemic investigation by the physician demonstrated bilateral pleural effusions of unknown origin. The patient had a past history of breast cancer; however, no metastasis was identified via malignant cells through cytology, laboratory findings, radiographs, CT, and MRI. After the diagnosis of Vogt-Koyanagi-Harada (VKH) disease was made, the patient was treated with local and systemic steroid including high-dose intravenous corticosteroids, and 150 mg of cyclosporine per day. Seventy days after the second high-dose of intravenous corticosteroids, these medications brought a complete resolution of both choroidal and retinal detachment. VKH disease associated with SAPHO syndrome is rare. The combination of immunosuppressive drug and steroid might be helpful for severe cases of VKH disease.

Abstract
A search for massive coloured resonances which are pair-produced and decay into two jets is presented. The analysis uses 36.7 fb- 1 of s = 13 TeV pp collision data recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the background prediction is observed. Results are interpreted in a SUSY simplified model where the lightest supersymmetric particle is the top squark, t ~ , which decays promptly into two quarks through R-parity-violating couplings. Top squarks with masses in the range 100 GeV < m t ~ < 410 GeV are excluded at 95% confidence level. If the decay is into a b-quark and a light quark, a dedicated selection requiring two b-tags is used to exclude masses in the ranges 100 GeV < m t ~ < 470 GeV and 480 GeV < m t ~ < 610 GeV . Additional limits are set on the pair-production of massive colour-octet resonances.

Abstract
We reported a 69-year-old female who discontinued denosumab due to dental treatment and subsequently suffered rebound-associated vertebral fractures 10 months after the last injection. This case raised an alarm regarding the discontinuation of denosumab for dental treatment. Denosumab, a human monoclonal antibody administered by subcutaneous injection, to the best of our knowledge, is the only fully investigated inhibitor of receptor activator of nuclear factor kappa B ligand. Discontinuation of denosumab leads to bone turnover rebound and rapid bone mineral density loss. Several studies have reported rebound-associated vertebral fractures after discontinuation of denosumab. We report on a new case of rebound-associated vertebral fractures after discontinuation of denosumab. A 69-year-old female, who withdrew from denosumab treatment after 3 years due to maxillitis, presented to our hospital with severe low back pain without any history of trauma. Ten months had passed since the last injection. Magnetic resonance imaging showed five acute vertebral fractures, which appeared to be rebound-associated vertebral fractures caused by discontinuation of denosumab due to dental treatment. This case clearly demonstrates the risk of discontinuation of denosumab for dental treatment.

Abstract
The modification of the production of J / ψ , ψ ( 2 S ) , and Υ ( n S ) ( n = 1 , 2 , 3 ) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of 28 nb - 1 and 25 pb - 1 respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of J / ψ and ψ ( 2 S ) are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, R p Pb for J / ψ and Υ ( n S ) . No significant modification of the J / ψ production is observed while Υ ( n S ) production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions.

Abstract
A measurement of the mass of the W boson is presented based on proton-proton collision data recorded in 2011 at a centre-of-mass energy of 7 TeV with the ATLAS detector at the LHC, and corresponding to 4.6 fb - 1 of integrated luminosity. The selected data sample consists of 7.8 × 10 6 candidates in the W → μ ν channel and 5.9 × 10 6 candidates in the W → e ν channel. The W-boson mass is obtained from template fits to the reconstructed distributions of the charged lepton transverse momentum and of the W boson transverse mass in the electron and muon decay channels, yielding m W = 80370 ± 7 ( stat. ) ± 11 ( exp. syst. ) ± 14 ( mod. syst. ) MeV = 80370 ± 19 MeV , where the first uncertainty is statistical, the second corresponds to the experimental systematic uncertainty, and the third to the physics-modelling systematic uncertainty. A measurement of the mass difference between the W + and W - bosons yields m W + - m W - = - 29 ± 28 MeV.

Abstract
Measurements of transverse energy-energy correlations and their associated asymmetries in multi-jet events using the ATLAS detector at the LHC are presented. The data used correspond tos = 8 TeV proton-proton collisions with an integrated luminosity of 20.2fb - 1 . The results are presented in bins of the scalar sum of the transverse momenta of the two leading jets, unfolded to the particle level and compared to the predictions from Monte Carlo simulations. A comparison with next-to-leading-order perturbative QCD is also performed, showing excellent agreement within the uncertainties. From this comparison, the value of the strong coupling constant is extracted for different energy regimes, thus testing the running ofα s ( μ ) predicted in QCD up to scales over 1 TeV . A global fit to the transverse energy-energy correlation distributions yieldsα s ( m Z ) = 0.1162 ± 0.0011 (exp.) - 0.0070 + 0.0084 (theo.) , while a global fit to the asymmetry distributions yields a value ofα s ( m Z ) = 0.1196 ± 0.0013 (exp.) - 0.0045 + 0.0075 (theo.) .
