Abstract
Evaluation of the results of laryngeal transplantation (LT) in humans. Analysis of 3 bibliographic databases with the keywords "larynx, transplantation, autograft". In total, 626 abstracts were read and 25 articles selected. The main objective was to analyze the characteristics of laryngeal transplant patients. The accessory objectives comprised analysis of operative technique, immunosuppressive treatment and results. Four articles were selected for analysis. Two patients were transplanted after total laryngectomy for laryngeal carcinoma and 2 after laryngeal trauma. Three of the 4 patients had true transplantation with arterial, venous and neural microanastomosis. Two patients were decannulated and the tracheostomy tube was maintained in the other 2. Three of the 4 patients had good-quality phonation and could feed without a gastric tube. One patient died of carcinoma progression and 1 patient had to be explanted 14 years after transplantation. The number of LTs reported is too small for scientific determination of the place of this intervention in laryngology. The published results could, at first sight, suggest that the future of LT is uncertain. However, several elements, also suggest that otolaryngologists should continue to take an interest in this technique.

Abstract
Crohn's disease (CD) is a chronic inflammatory gut disorder. Molecular mechanisms underlying the clinical heterogeneity of CD remain poorly understood. MicroRNAs (miRNAs) are important regulators of gut physiology, and several have been implicated in the pathogenesis of adult CD. However, there is a dearth of large-scale miRNA studies for pediatric CD. We hypothesized that specific miRNAs uniquely mark pediatric CD. We performed small RNA-Seq of patient-matched colon and ileum biopsies from treatment-naive pediatric patients with CD (n = 169) and a control cohort (n = 108). Comprehensive miRNA analysis revealed 58 miRNAs altered in pediatric CD. Notably, multinomial logistic regression analysis revealed that index levels of ileal miR-29 are strongly predictive of severe inflammation and stricturing. Transcriptomic analyses of transgenic mice overexpressing miR-29 show a significant reduction of the tight junction protein gene Pmp22 and classic Paneth cell markers. The dramatic loss of Paneth cells was confirmed by histologic assays. Moreover, we found that pediatric patients with CD with elevated miR-29 exhibit significantly lower Paneth cell counts, increased inflammation scores, and reduced levels of PMP22. These findings strongly indicate that miR-29 upregulation is a distinguishing feature of pediatric CD, highly predictive of severe phenotypes, and associated with inflammation and Paneth cell loss.

Abstract
Als Meralgia paraesthetica (MP) bezeichnet man eine zu den neurologischen Engpasssyndromen zählende Schädigung des aus dem Plexus lumbalis entspringenden sensiblen N. cutaneus femoris lateralis. Symptome sind temporäre oder bleibende Parästhesien und Schmerzen an der Vorder- und Außenseite des Oberschenkels. Die MP kann idiopathisch auftreten, sich genuin als z. B. „seat belt syndrome“ oder „Jeans-Syndrom“ verwirklichen, sie kann aber auch Folge eines operativen Eingriffs oder einer chirurgischen bzw. intensivmedizinischen Lagerung sein. Im Fokus stehen hierbei in der Literatur die Steinschnitt-, die Bauch- und die „Beach-chair“-Lagerung. Analysiert wurden 21 Beschwerden über eine postoperativ erstmals aufgetretene MP, die bei der Gutachterkommission für ärztliche Behandlungsfehler bei der Ärztekammer Nordrhein im Verlauf der letzten 10 Jahre eingereicht wurden. Unter diesen konnten 6 Fälle als Lagerungsschaden nach Steinschnittlagerung identifiziert werden; in 3 Fällen trat eine MP nach Rückenlagerung auf; die Ätiologie konnte nicht sicher geklärt werden. In 12 Fällen wurde die MP als direkte Operationskomplikation erkannt. Pathophysiologie, Inzidenz und Verlauf sowie juristische Implikationen der lagerungsbedingten MP werden beschrieben. Als hauptsächlicher Pathomechanismus wird eine Druckschädigung des Nervs an seiner Kreuzungsstelle mit dem Leistenband diskutiert. Wenngleich alle hier vorgestellten Fälle nach der Steinschnittlagerung auftraten, scheint sich die Komplikation nach Literaturdaten auch bei anderen Lagerungsarten, am häufigsten möglicherweise bei Bauchlagerungen, zu verwirklichen. Dies erklärt auch die zunehmenden Fallberichte einer MP nach Bauchlagerung bei COVID-19-Patient*innen. Eine sichere Vermeidung der lagerungsbedingten Komplikation erscheint aufgrund der anatomischen Variabilität des Nervenverlaufs und der unklaren Pathomechanismen nicht möglich.

Abstract
Experiments and simulations are performed to study filamentation and generation of acoustic waves in water by loosely focused multi-millijoules laser pulses. When the laser pulse duration is increased from femtosecond to nanosecond duration, a transition is observed from a filamentary propagation with extended and low energy density deposition to a localized breakdown, related to high energy density deposition. The transition suggests that Kerr self-focusing plays a major role in the beam propagation dynamics. As a result, the shape, the amplitude and the spectrum of the resulting pressure wave present a strong dependence on the laser pulse duration.

Abstract
Because of a painful right-sided coxarthrosis a 57-year-old female patient underwent a cementless total arthroplasty under general anesthesia. Except for Asperger's syndrome and an occlusion of a vein in her left eye she stated no other diseases or complaints, especially no cardiac problems. Postoperatively she developed neurological symptoms of left-sided hemiparesis and hemihypesthesia. A cranial computer tomography was performed and a right-sided infarction of the thalamic region was found. A patent foramen ovale (PFO) and atrial septal aneurysm were detected 5 days later. The incidence of a PFO is given as 25% of the population. A paradoxical air embolism in the presence of a PFO is a feared complication in neurosurgical interventions in a semi-sitting or sitting position. Corpuscular emboli, such as bone, cement, fat or wound debris may be the reason for paradoxical embolisms in combination especially with partial or total hip replacement. The kind of embolism in the case described could not be clarified. Deep vein thrombosis or cardiac arrhythmia could be excluded. Therefore, it can be considered most likely that the operation site was the source of the embolism. The trigger for a paradoxical embolism is a reversal of the pressure difference between the right and left atria: normally the left atrial pressure exceeds the right atrial pressure by ca. 2-4 mm Hg, resulting possibly in a small clinically irrelevant left-to-right shunt. If the pulmonary arterial circulation is compromised and pulmonary vascular resistance increases, the pressure gradient between the left and right atria reverses and a right-to-left shunt can occur causing a paradoxical embolism. Positive end-expiratory pressure (PEEP) ventilation during anesthesia could be an important reason for a shunt reversal between the right and left atria and therefore favoring a paradoxical embolism but the pathophysiological role of PEEP has not yet been finally clarified.

Abstract
A 61-year-old woman underwent a tension-free vaginal tape (TVT) operation due to stress incontinence. After technically difficult spinal anesthesia with two attempts the patient developed symptoms of nerve irritation, complained about neckache and headache and showed signs of agitation. The regimen was shifted to general anesthesia and surgery was performed. Because of postoperatively persistent headache and sensory disturbances an MRI scan of the lumbar spine was performed on the first postoperative day without pathological findings. The patient was able to leave the hospital after 1 week with significant relief of symptoms but 3 weeks later she developed neurocognitive impairment with memory deficits. A second MRI scan of the head now showed signs of disturbance of CSF circulation with hydrocephalus. Treatment was performed with drainage and ventriculoperitoneal shunt. Further evaluation showed a severe, multisegmental arachnoiditis and the patient developed a progressive paraparesis. The patient presented her case for assessment to a commission on medical malpractice 13 months after anesthesia. The commission detected no treatment errors. In connection to the case report a literature review of characteristics and etiologies of chronic adhesive arachnoiditis is given, which is a known but very rare complication of spinal anesthesia or similar procedures.

Abstract
Introduction
Poor sleep is common among adolescents and has been linked with school absenteeism. Though improved sleep has been associated with improved school outcomes, intervention programs for insufficient sleep are not standard in schools, few have used an individualized approach, and none have focused on youth with absenteeism. We conducted an open trial of the feasibility, acceptability, and initial impact of our school-based sleep promotion program among adolescents.
Methods
Participants included 8th and 9th grade students with mild absenteeism, insufficient sleep, and sleep timing shift on the School Sleep Habits Survey (SSHS). The program included a smartphone-based sleep diary and 1-2 tailored sessions with a school staff member. Participants completed baseline and follow-up research assessments. The sleep program focused on education about sleep; cognitive strategies targeting sleep beliefs; stimulus control; and regularization of sleep and wake. We descriptively report program feasibility, acceptability, and change in sleep duration.
Results
Of 33 participants approached by school staff, 12 agreed to participate and 10 completed the study. Seven participants had two program sessions and 5 participants had one program session. Sleep duration increased by 19 minutes across the entire week based on daily sleep diary, and by 31 minutes on weekdays on the SSHS. Most participants (89%) reported that the program was not a burden on their time, that the program length was just right (88%), and that they were likely to participate in research again (75%). While program feasibility was high, most youth (56%) rated program relevance as low or unknown. The most salient implementation barrier was the challenge of embedding the program into each school’s existing procedures.
Conclusion
A school-based sleep promotion program for adolescents with insufficient sleep and mild absenteeism is feasible, acceptable, and associated with improved sleep. An individualized approach, with sessions delivered by school staff, shows great promise for being feasible and clinically significant. Future work should focus on selecting a sample of youth with greater investment in the program to improve school attendance and implementing the program flexibly and with fidelity across schools.

Abstract
OBJECTIVE Circumferential pharyngolaryngectomy is performed for advanced pharyngeal tumor or in a context of postradiation recurrence. Several free or pedicle flaps have been described for pharyngeal defect reconstruction, with choice at the surgeon's discretion. The aim of this study was to evaluate long-term swallowing function according to the type of flap used for reconstruction. MATERIAL AND METHOD A multicenter retrospective study was conducted from January to September 2016 within the French GETTEC head and neck tumor study group. All patients in remission after circumferential pharyngolaryngectomy were included and filled out the Deglutition Handicap Index (DHI) questionnaire and underwent swallowing function fiberoptic endoscopy assessment. 46 patients (39 men, 7 women) were included. Reconstruction used a tubularized forearm free flap (FFF group) in 19 cases, pectoralis major myocutaneous flap (PMMF group) in 15 cases and free jejunum flap (FJF group) in 12 cases. RESULTS Mean DHI was 24: 20 in the FFF group, 23 in the FJF group and 25 in the PMMF group, without significant differences. 27 patients had normal swallowing, 9 mixed diet, 8 liquid diet and 3 were fed by gastrostomy. On endoscopy, free flaps (FJF and FFF) were associated with significantly greater rates of normal swallowing of saliva and yogurt than in the PMMF group (P=0.04). CONCLUSION Type of flap reconstruction after circumferential pharyngolaryngectomy had no significant impact on postoperative swallowing function assessed on the self-administered DHI questionnaire.

Abstract
When a flying object becomes supersonic, a concomitant increase in drag leads to a considerable rise in fuel consumption. We show experimentally that an embarked terawatt femtosecond laser can significantly decrease this drag. We measured a 50% transient reduction of drag on a test model placed in a supersonic wind tunnel at Mach 3. This effect was initiated by the thin hot air column created in front of the supersonic object by filamentation of the laser pulse. We also show that this technique offers possibilities for steering.

Abstract
During the 2017 IFOS international congress in Paris, a roundtable discussion on the topic of functional and aesthetic rhinoplasty was organised. Five experts, from the five continents and renown in the field of rhinoplasty, were brought together to discuss the issue from an international perspective and to put forward a consensus or on the contrary practical differences. Five questions were put to the experts beforehand to guarantee independent answers, which were then discussed during the roundtable. The questions were the following: - What are the age limits for achieving a rhinoplasty? - Do you use objective measurements before, during and after surgery? (facial landmarks, airflow, peroperative measurements) - How do you manage the preoperative general information and computer imaging of the patient? - What are the indications in your practice to perform a CT-scan or endoscopic examination before doing a rhinoplasty? - What kind of graft or prosthesis do you use for an augmentation rhinoplasty? This paper offers a synthesis of the roundtable based on the experts' answers to the different questions.

Abstract
This work aims at reconsidering several interpretations coexisting in the recent literature concerning nonlinear susceptibilities in supercooled liquids. We present experimental results on glycerol and propylene carbonate, showing that the three independent cubic susceptibilities have very similar frequency and temperature dependences, for both their amplitudes and phases. This strongly suggests a unique physical mechanism responsible for the growth of these nonlinear susceptibilities. We show that the framework proposed by two of us [J.-P. Bouchaud and G. Biroli, Phys. Rev. B 72, 064204 (2005)PRBMDO1098-012110.1103/PhysRevB.72.064204], where the growth of nonlinear susceptibilities is intimately related to the growth of glassy domains, accounts for all the salient experimental features. We then review several complementary and/or alternative models and show that the notion of cooperatively rearranging glassy domains is a key (implicit or explicit) ingredient to all of them. This paves the way for future experiments, which should deepen our understanding of glasses.

Abstract
Despite the strong interest in optoelectronic devices working in the deep ultraviolet range, no suitable low cost, large-area, high-quality AlN substrates have been available up to now. The aim of this work is the selective area growth of AlN nanocolumns by plasma assisted molecular beam epitaxy on polar (0001) and semi-polar (11-22) GaN/sapphire templates. The resulting AlN nanocolumns are vertically oriented with semi-polar {1-103} top facets when grown on (0001) GaN/sapphire, or oriented at 58° from the template normal and exposing {1-100} non-polar top facets when growing on (11-22) GaN/sapphire, in both cases reaching filling factors ≥80%. In these kinds of arrays each nanostructure could function as a building block for an individual nano-device or, due to the large filling factor values, the overall array top surfaces could be seen as a quasi (semi-polar or non-polar) AlN pseudo-template.

Abstract
BACKGROUND Immunological fecal occult blood tests (FIT) are superior in detecting colorectal cancer and its precursors compared to conventional Guajac-based tests. Besides quantitative, laboratory-based FITs qualitative, office-based FITs are increasingly employed. Studies have shown major variation of these tests with respect to sensitivity and specificity, which is most probably caused by different detection limits. In the present study we therefore determined and compared the detection limits and other criteria of commercial FITs. METHODS We determined the detection limits for 21 qualitative and one quantitative FIT using commercial control solutions with defined hemoglobin (Hb) concentrations. These detection limits were compared with the manufacturers' data. RESULTS The detection limits of the tests showed a wide range of 2 to over 60 µg Hb per gram stool. In many cases the detection limits we determined were not in accordance with the manufacturers' data. Two tests didn't show a positive reaction even with the highest hemoglobin concentration of 440 ng/mL. On the other hand one test showed a positive reaction even at the lowest hemoglobin concentration of 25 ng/mL. CONCLUSION The large differences in the detection limits found in this study are consistent with observations of large variation of sensitivity and specificity of qualitative FITs in screening practice. Proper clinical validation of each FIT is to be required before admission for colorectal cancer screening. An additional regular quality control, i. e. by means of external quality control measures and documentation of results of colonoscopies following positive tests results, should be mandatory.

Abstract
We report on the formation of polarity inversion in ordered (In,Ga)N/GaN nanocolumns grown on a Ti-masked GaN-buffered sapphire substrate by plasma assisted molecular beam epitaxy. High-resolution transmission electron microscopy and electron energy-loss spectroscopy reveal a stacking fault-like planar defect at the homoepitaxial GaN interface due to Ti incorporation, triggering the generation of N-polar domains in Ga-polar nanocolumns. Density functional theory calculations are applied to clarify the atomic configurations of a Ti monolayer occupation on the GaN (0002) plane and to prove the inversion effect. The polarity inversion leads to an enhanced indium incorporation in the subsequent (In,Ga)N segment of the nanocolumn. This study provides a deeper understanding of the effects of Ti mask in the well-controlled selective area growth of (In,Ga)N/GaN nanocolumns.

Abstract
BACKGROUND Sentinel lymph-node (LN) biopsy (SLNB) is a valuable tool to assess the regional LN status in Merkel cell carcinoma (MCC). However, its prognostic value is still debated. This study was undertaken to assess SLNB usefulness for MCC management and to determine the impact of SLNB status on disease-free survival (DFS) and overall survival (OS) by comparing SLNB-positive versus -negative patients according to demographic, clinical and treatment characteristics. PATIENTS AND METHODS In this retrospective, multicenter observational study, SLNB was proposed to all patients referred for clinically N0 MCC. Treatment schedule consisted of wide-margin surgical resection of primary MCC followed by adjuvant radiation therapy (aRT) to the primary site and, for SLNB-positive patients, radical LN dissection followed by regional aRT. Univariate and multivariate analyses determined factors associated with DFS and OS. RESULTS Among 87 patients with successful SLNB, 21 (24.1%) were SLNB-positive. Median follow-up for the entire series was 39 months; respective 3-year DFS and OS rates were 73% and 81.4%, respectively. Univariate analysis (all patients) identified SLNB-negativity as being associated with prolonged OS (P = 0.013) and aRT (all sites considered) was associated with longer DFS (P = 0.004) and OS (P = 0.018). Multivariate analysis (all patients) retained SLNB status and aRT (all sites considered) as being associated with improved DFS (P = 0.014 and 0.0008) and OS (P = 0.0020 and 0.0019). Moreover, for SLNB-negative patients, tumor-bed irradiation was also significantly associated with prolonged DFS (P = 0.006) and OS (P = 0.014). CONCLUSIONS The present study demonstrates that SLNB-negativity is a strong predictor of longer DFS and OS in stage I and II MCC patients. The similar benefit for aRT on tumor bed observed in this study has to be confirmed by a prospective study. The results advocate for SLNB being considered to all MCC patients.

Abstract
3D InGaN/GaN microstructures grown by metal organic vapor phase epitaxy (MOVPE) and molecular beam epitaxy (MBE) have been extensively studied using a range of electron microscopy techniques. The growth of material by MBE has led to the growth of cubic GaN material. The changes in these crystal phases has been investigated by Electron Energy Loss Spectroscopy, where the variations in the fine structure of the N K‐edge shows a clear difference allowing the mapping of the phases to take place. GaN layers grown for light emitting devices sometimes have cubic inclusions in the normally hexagonal wurtzite structures, which can influence the device electronic properties. Differences in the fine structure of the N K‐edge between cubic and hexagonal material in electron energy loss spectra are used to map cubic and hexagonal regions in a GaN/InGaN microcolumnar device. The method of mapping is explained, and the factors limiting spatial resolution are discussed.

Abstract
INTRODUCTION/AIM Our aim was to generate, optimize and validate a self-administered bleeding assessment tool (self-BAT) for von Willebrand disease (VWD). METHODS In Phase 1, medical terminology in the expert-administered International Society on Thrombosis and Haemostasis (ISTH)-BAT was converted into a Grade 4 reading level to produce the first version of the Self-BAT which was then optimized to ensure agreement with the ISTH-BAT. In Phase 2, the normal range of bleeding scores (BSs) was determined and test-retest reliability analysed. In Phase 3, the optimized Self-BAT was tested as a screening tool for first time referrals to the Haematology clinic. RESULTS Bleeding score from the final optimized version of the Self-BAT showed an excellent intra-class correlation coefficient (ICC) of 0.87 with ISTH-BAT BS in Phase 1. In Phase 2, the normal range of BSs for the optimized Self-BAT was determined to be 0 to +5 for females and 0 to +3 for males and excellent test-retest reliability was shown (ICC = 0.95). In Phase 3, we showed that a positive Self-BAT BS (≥6 for females, ≥4 for males) has a sensitivity of 78%, specificity of 23%, positive predictive value (PPV) of 0.15 and negative predictive value (NPV) of 0.86 for VWD; these figures improved when just the females were analysed; sensitivity of 100%, specificity of 21%, PPV = 0.17 and NPV = 1.0. CONCLUSION We show an optimized Self-BAT can generate comparable BS to the expert-administered ISTH-BAT and is a reliable, effective screening tool to incorporate into the assessment of individuals, particularly women, referred for a possible bleeding disorder.

Abstract
The growth of ordered arrays of InGaN/GaN nanocolumnar light emitting diodes by molecular beam epitaxy, emitting in the blue (441 nm), green (502 nm), and yellow (568 nm) spectral range is reported. The device active region, consisting of a nanocolumnar InGaN section of nominally constant composition and 250 to 500 nm length, is free of extended defects, which is in strong contrast to InGaN (planar) layers of similar composition and thickness. Electroluminescence spectra show a very small blue shift with increasing current (almost negligible in the yellow device) and line widths slightly broader than those of state-of-the-art InGaN quantum wells.

Abstract
Although inflammatory myofibroblastic tumours (IMTs) have been accepted as a clonal neoplasm, their pathology is poorly understood due to variable presentation. There is no identifiable cause and they are usually observed as tumour growth combined with inflammation. In the current WHO classification, IMTs are designated as intermediate malignancies. In terms of biological potential, IMTs are classified under 'rarely metastasizing'. IMTs are rare in the maxillary sinus but, when reported, can be locally aggressive or even destructive if they invade the orbit. The authors present a brief clinical report describing a five-year-old girl with a slow-growing mass in the right maxillary sinus extending into the lacrimal sac and its management.

Abstract
OBJECTIVE To present the guidelines of the French Oto-Rhino-Laryngology--Head and Neck Surgery Society (SFORL) concerning the management of somatic pain induced by the treatment of head and neck cancer, and in particular the management of early and late post-surgical pain. METHODS A multidisciplinary work group conducted a review of the scientific literature on the study topic. An editorial group subsequently read the resulting guidelines before validation. RESULTS It is recommended to prevent onset of pain caused by malpositioning on the operating table, as well as pain related to postoperative care. During surgery, it is recommended to spare nerve and muscle structures as far as possible to limit painful sequelae. Management of early postoperative pain upon tumor resection and flap harvesting sites requires patient-controlled analgesia by morphine pump. Physical therapy is recommended after flap harvesting to minimize painful sequelae. CONCLUSION Preventive and curative measures should be undertaken for appropriate management of post-surgical pain in the treatment of head and neck cancers.

Abstract
The livelihood of many coastal communities in the Pacific Islands is directly dependent on the health of adjacent
coral reefs. Reduction in water quality and over-harvesting of herbivorous fish are known to drive reef ecosystems
towards a more degraded state. Community-based resource management practices have the potential to improve
damaged reefs but quantitative data on their effectiveness remains largely unreported. This study investigated how
land use changes and implementation of marine management influenced water quality, herbivorous fish biomass and
reef condition of Marovo Lagoon in the Solomon Islands. Four study sites were located along a gradient of water quality,
with two of the sites located inside marine protected areas (MPAs) designated in 2006. The results suggest that water
quality in coastal areas adjacent to catchments modified by logging was negatively impacted. However, following natural
revegetation of bare soil in the catchment between 2000 and 2010, water quality improved at all sites. The biomass of
herbivorous fish was significantly greater in the MPAs compared to other sites and, importantly, we detected an increase
in herbivore biomass between 2005 and 2008. Inshore reefs adjacent to logging operations had significantly lower coral
cover and higher macroalgal cover than those offshore. Between 2005 and 2008 all sites showed an increase in crustose
coralline algae cover and a decrease in turf algae colonising rocks, with the changes indicative of improving reef health.
Collectively, these results indicate that reduction in logging and implementation of community-based management can
have a positive influence on reefs in Marovo Lagoon.

Abstract
BACKGROUND Soft-tissue sarcomas (STSs) are rare tumors with varied histological presentations. Management and treatment are thus complex, but crucial for patient outcomes. We assess adherence to adult STS management guidelines across two French regions (10% of the French population). We also report standardized incidence. PATIENTS AND METHODS STS patients diagnosed from 1 November 2006 to 31 December 2007 were identified from pathology reports, medical hospital records, and cancer registries. Guideline adherence was assessed by 23 criteria (validated by Delphi consensus method), and age and sex-standardized incidence rates estimated. Associations between patient, treatment, and institutional factors and adherence with three major composite criteria relating to diagnostic imaging and biopsy as well as multidisciplinary team (MDT) case-review are reported. RESULTS Two hundred and seventy-four patients were included (57.7% male, mean age 60.8 years). Practices were relatively compliant overall, with over 70% adherence for 10 criteria. Three criteria with perfect Delphi consensus had low adherence: receiving histological diagnosis before surgery, adequacy of histological diagnosis (adherence around 50% for both), and MDT discussion before surgery (adherence <30%). Treatment outside of specialized centers was associated with lower adherence for all three composite criteria, and specific tumor sites and/or features were associated with lower adherence for diagnostic imaging, methods, and MDT meetings. STS standardized incidence rates were 4.09 (European population) and 3.33 (World) /100 000 inhabitants. CONCLUSIONS Initial STS diagnosis and treatment across all stages (imaging, biopsy, and MDT meetings) need improving, particularly outside specialized centers. Educational interventions to increase surgeon's sarcoma awareness and knowledge and to raise patients' awareness of the importance of seeking expert care are necessary.

Abstract
Selective area growth of In(Ga)N/GaN nanocolumns was performed on GaN-buffered Si(111) substrates by plasma-assisted molecular beam epitaxy. Undoped and Si-doped GaN buffer layers were first grown on Si(111) substrates, showing photoluminescence excitonic emission without traces of other low energy contributions, in particular, the yellow band. The GaN buffer surface roughness (between 10 and 14 nm, the rms value in a 10 × 10 μm(2) area) was low enough to allow the fabrication of a thin (7 nm thick) well defined Ti nanohole mask, for the selective area growth. Ordered In(Ga)N/GaN nanocolumns emitting from the ultraviolet (3.2 eV) to the infrared (0.78 eV) were obtained. The morphology and the emission efficiency of the In(Ga)N/GaN nanocolumns emitting at a given wavelength could be substantially improved by tuning the In/Ga and total III/N ratios. An estimated internal quantum efficiency of 36% was derived from photoluminescence data for green emitting nanocolumns.

Abstract
We demonstrate the potential of low-loss electron energy-loss spectroscopy in transmission electron microscopy as a quick and straightforward method to determine the local indium compositions in (In,Ga)N/GaN nanowires. The (In,Ga)N/GaN nanowire heterostructures are grown by plasma assisted molecular beam epitaxy on Si(111) substrates in a self-assembled way, and on patterned GaN templates in an ordered way. A wide range of indium contents is realized by varying the substrate temperatures. The plasmon peak in low-loss electron energy-loss spectroscopy exhibits a linear relation with respect to indium concentration in (In,Ga)N nanowires, allowing for a direct compositional analysis. The high spatial resolution of this method in combination with structural information from transmission electron microscopy will contribute to a basic understanding of the lattice pulling effect during (In,Ga)N/GaN nanowire growth.
