Abstract
Dark matter (DM) particles with sufficiently large cross sections may scatter as they travel through Earth's bulk. The corresponding changes in the DM flux give rise to a characteristic daily modulation signal in detectors sensitive to DM-electron interactions. Here, we report results obtained from the first underground operation of the DAMIC-M prototype detector searching for such a signal from DM with MeV-scale mass. A model-independent analysis finds no modulation in the rate of 1 e^{-} events with sidereal period, where a DM signal would appear. We then use these data to place exclusion limits on DM in the mass range [0.53,2.7] MeV/c^{2} interacting with electrons via a dark photon mediator. Taking advantage of the time-dependent signal we improve by ∼2 orders of magnitude on our previous limit obtained from the total rate of 1 e^{-} events, using the same dataset. This daily modulation search represents the current strongest limit on DM-electron scattering via ultralight mediators for DM masses around 1 MeV/c^{2}.

Abstract
Objective: To develop and pilot a web-based patient decision aid (PDA) to support people living with motor neurone disease (plwMND) considering having a gastrostomy tube placed. Methods: In Phase 1, content and design were informed by semi-structured interviews, literature reviews and a prioritization survey. In Phase 2, the prototype PDA was tested with users and developed iteratively with feedback from surveys and 'think-aloud' interviews. Phase 1 and 2 participants were plwMND, carers and healthcare professionals (HCPs). In Phase 3, the PDA was evaluated by plwMND using validated questionnaires and HCPs provided feedback in focus groups. Results: Sixteen plwMND, 16 carers and 25 HCPs took part in Phases 1 and 2. Interviews and the literature review informed a prioritization survey with 82 content items. Seventy-seven per cent (63/82) of the content of the PDA was retained. A prototype PDA, which conforms to international standards, was produced and improved during Phase 2. In Phase 3, 17 plwMND completed questionnaires after using the PDA. Most plwMND (94%) found the PDA completely acceptable and would recommend it to others in their position, 88% had no decisional conflict, 82% were well prepared and 100% were satisfied with their decision-making. Seventeen HCPs provided positive feedback and suggestions for use in clinical practice. Conclusion: Gastrostomy Tube: Is it for me? was co-produced with stakeholders and found to be acceptable, practical and useful. Freely available from the MND Association website, the PDA is a valuable tool to support the shared decision-making process for gastrostomy tube placement.

Abstract
We report constraints on sub-GeV dark matter particles interacting with electrons from the first underground operation of DAMIC-M detectors. The search is performed with an integrated exposure of 85.23 g days, and exploits the subelectron charge resolution and low level of dark current of DAMIC-M charge-coupled devices (CCDs). Dark-matter-induced ionization signals above the detector dark current are searched for in CCD pixels with charge up to 7e^{-}. With this dataset we place limits on dark matter particles of mass between 0.53 and 1000 MeV/c^{2}, excluding unexplored regions of parameter space in the mass ranges [1.6,1000] MeV/c^{2} and [1.5,15.1] MeV/c^{2} for ultralight and heavy mediator interactions, respectively.

Abstract
The SNO+ Collaboration reports the first evidence of reactor antineutrinos in a Cherenkov detector. The nearest nuclear reactors are located 240 km away in Ontario, Canada. This analysis uses events with energies lower than in any previous analysis with a large water Cherenkov detector. Two analytical methods are used to distinguish reactor antineutrinos from background events in 190 days of data and yield consistent evidence for antineutrinos with a combined significance of 3.5σ.

Abstract
We present constraints on the existence of weakly interacting massive particles (WIMPs) from an 11 kg d target exposure of the DAMIC experiment at the SNOLAB underground laboratory. The observed energy spectrum and spatial distribution of ionization events with electron-equivalent energies >200 eV_{ee} in the DAMIC CCDs are consistent with backgrounds from natural radioactivity. An excess of ionization events is observed above the analysis threshold of 50 eV_{ee}. While the origin of this low-energy excess requires further investigation, our data exclude spin-independent WIMP-nucleon scattering cross sections σ_{χ-n} as low as 3×10^{-41} cm^{2} for WIMPs with masses m_{χ} from 7 to 10 GeV c^{-2}. These results are the strongest constraints from a silicon target on the existence of WIMPs with m_{χ}<9 GeV c^{-2} and are directly relevant to any dark matter interpretation of the excess of nuclear-recoil events observed by the CDMS silicon experiment in 2013.

Abstract
We report direct-detection constraints on light dark matter particles interacting with electrons. The results are based on a method that exploits the extremely low levels of leakage current of the DAMIC detector at SNOLAB of 2-6×10^{-22} A cm^{-2}. We evaluate the charge distribution of pixels that collect <10e^{-} for contributions beyond the leakage current that may be attributed to dark matter interactions. Constraints are placed on so-far unexplored parameter space for dark matter masses between 0.6 and 100 MeV c^{-2}. We also present new constraints on hidden-photon dark matter with masses in the range 1.2-30 eV c^{-2}.

Abstract
New results are reported from the operation of the PICO-60 dark matter detector, a bubble chamber filled with 52 kg of C_{3}F_{8} located in the SNOLAB underground laboratory. As in previous PICO bubble chambers, PICO-60 C_{3}F_{8} exhibits excellent electron recoil and alpha decay rejection, and the observed multiple-scattering neutron rate indicates a single-scatter neutron background of less than one event per month. A blind analysis of an efficiency-corrected 1167-kg day exposure at a 3.3-keV thermodynamic threshold reveals no single-scattering nuclear recoil candidates, consistent with the predicted background. These results set the most stringent direct-detection constraint to date on the weakly interacting massive particle (WIMP)-proton spin-dependent cross section at 3.4×10^{-41} cm^{2} for a 30-GeV c^{-2} WIMP, more than 1 order of magnitude improvement from previous PICO results.

Abstract
We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range 1.2-30 eV c^{-2} with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter κ is competitive with constraints from solar emission, reaching a minimum value of 2.2×10^{-14} at 17 eV c^{-2}. These results are the most stringent direct detection constraints on hidden-photon dark matter in the galactic halo with masses 3-12 eV c^{-2} and the first demonstration of direct experimental sensitivity to ionization signals <12 eV from dark matter interactions.

Abstract
Room temperature mid-infrared experiments between 600 and 1600 cm(-1) have been performed on crystalline deoxycytidine as a function of pressure up to about 10 GPa. The wavenumbers of most vibrational modes shift to higher values with increasing pressures except for a mode near 840 cm(-1). Assignments for the observed modes are made on the basis of work published in the literature. Several anomalies are noted near 4.7 GPa, suggesting a phase transition. Our results for deoxycytidine are compared to similar measurements on cytidine.

Abstract
A seven-week-old infant suffered a closed segmental fracture of the left tibia and fibula complicated by vascular disruption and a secondary compartment syndrome. Initial orthopedic assessment revealed a clinically mottled, cool, pulseless extremity 4 hr post-injury. Radiologic investigations showed multiple displaced fractures of both the tibia and fibula. The infant underwent four compartment fasciotomies and intramedullary nailing of the tibial fractures. The vascularity of the limb failed to improve significantly. Angiograms done 22 hr post-injury revealed disruption of arterial inflow just distal to the bifurcation of the tibial peroneal trunk and posterior tibial artery. Urgent revascularization utilizing a contralateral greater saphenous vein graft was undertaken with a successful outcome. Despite delay in transport from the community hospital and lack of definitive management of the vascular injury, the infant has had a good-to-excellent functional outcome.
