We found a total of 21 additional derivatized compounds. Using self-reported demographic factors from our participants, we found no correlation between these breath carbonyls and age, gender, body mass index (BMI), ethnicity or smoking habit (tobacco and marijuana). This work was preceded by a small confounders study, which was intended to refine our breath collection procedure. We found that breath aldehyde levels can be affected by participants' using scented hygiene products such as lotions and mouthwashes, while collecting consecutive breath samples, rinsing the mouth with water, and filtering inspired air did not have an effect. Using these parameters to guide our sampling, subjects were instructed to avoid the prior conditions to providing a breath sample for our study. © 2020 IOP Publishing Ltd.Efficient and noble metal-free co-catalyst loading is an effective solution for separating and transferring photo-generated carriers and lowering the overpotential in photocatalytic H2 evolution activity. In this work, we designed and prepared a series of novel NiCoP/Mn0.3Cd0.7S (NCP/MCS) composites by modifying MCS nanorods with the co-catalyst NCP using a simple calcination method. Notably, the 10-NCP/MCS composite displays the optimum photocatalytic H2 evolution rate of 118.5 mmol g-1 h-1 under visible-light irradiation. This is approximately 3.39 times higher than that of pure MCS. The corresponding apparent quantum efficiency is 10.2 % at 420 nm. The superior photocatalytic activity of the NCP/MCS composites can be attributed to the efficient separation of photogenerated carriers caused by the intimate heterojunction interface between NCP and MCS, smaller transfer resistance, and lower overpotential of NCP. Moreover, the NCP/MCS composites exhibit remarkable photostability. A plausible mechanism is proposed. © 2020 IOP Publishing Ltd.OBJECTIVE To test the reliability of immediate replication of muscle cramp characteristics induced with different electrical stimulation protocols. APPROACH Five (age 33.8 ± 5.7 y, 60% male) and ten (age 47.4 ± 11.7 y, 60% male) participants completed independent discovery and validation cohorts, respectively. This was to identify a protocol that resulted in consistent muscle cramp characteristics (discovery), and to examine the test-retest reliability of the identified protocol (validation). Electrical stimulation (150 burst) at abductor hallucis motor-point was used to induce muscle cramps with 4 Hz increments in stimulation frequency (8 to 32 Hz) or until muscle cramp was first evident, followed by refinement (2 and 1 Hz) until at least two muscle cramps occurred. This defined the cramp threshold frequency, and concurrent electromyogram activity and duration of the cramp were quantified. this website The discovery cohort involved three separate randomised sessions where intervals between stimulation was 60, 90, and 120iable method for inducing repeatable muscle cramps in abductor hallucis. © 2020 Institute of Physics and Engineering in Medicine.In this paper we formulate a nonlocal density functional theory of inhomogeneous water. We model a water molecule as a couple of oppositely charged sites. The negatively charged sites interact with each other through the Lennard-Jones potential (steric and dispersion interactions), square-well potential (short-range specific interactions due to electron charge transfer), and Coulomb potential, whereas the positively charged sites interact with all types of sites by applying the Coulomb potential only. Taking into account the nonlocal packing effects via the fundamental measure theory (FMT), dispersion and specific interactions in the mean-field approximation, and electrostatic interactions at the many-body level through the random phase approximation, we describe the liquid-vapour interface. We demonstrate that our model without explicit account of the association of water molecules due to hydrogen bonding and with explicit account of the many-body electrostatic interactions at the many-body level is able to describe the liquid-vapour coexistence curve and the surface tension at the ambient pressures and temperatures. We obtain very good agreement with available in the literature MD simulation results for density profile of liquid-vapour interface at ambient state parameters. The formulated theory can be used as a theoretical background for describing of the capillary phenomena, occurring in micro- and mesoporous materials. © 2020 IOP Publishing Ltd.OBJECTIVE Portable oximetry has been shown to be a promising candidate for large-scale obstructive sleep apnea screening. In polysomnography (PSG), the gold standard OSA diagnosis test, the oxygen desaturation index (ODI) is usually computed from desaturation events occurring during sleep periods only, i.e., overnight desaturations occurring during or overlapping with a wake state are excluded. However, for unattended home oximetry, all desaturations are taken into account since no reference electroencephalogram is available for sleep staging. We aim to evaluate the hypothesis that the predictive power of oximetry for OSA screening is not impaired when reference sleep stages are not available. APPROACH We used a PSG clinical database of 887 individuals from a representative São Paulo (Brazil) population sample. Using features derived from the oxygen saturation time series and demographic information, OxyDOSA, a published machine learning model, was trained to distinguish between non-OSA and OSA individuals us and Engineering in Medicine.In this paper, the effect of BC3, C3N and C3N4 substrates on the atomic and electronic properties of MoS2 were systematically investigated using first-principles calculations. Our result shows that the MoS2/BC3 and MoS2/C3N4 heterostructures are a direct semiconductor with band gaps of 0.4 and 1.74 eV, respectively, while MoS2/C3N is a metal. Furthermore, we study the influence of strain and electric field on the electronic structure of these van der Waals heterostructures. The MoS2/BC3 heterostructure under -2% strain is a semiconductor with a direct band gap of 0.3 eV and under compressive strains larger than -4%, it transforms into a metal where the metallic character is maintained up to strains larger than -6%. The direct band gap decreases with increasing tensile strain to 0.35 eV (at +2%) and 0.3 eV (at +4%), while for strain (>+6%) a direct-indirect band gap transition is predicted to occur. For the MoS2/C3N heterostructure the metallic character persists for all strains considered. On applying an electric field, the electronic properties of MoS2/C3N 4 are modified and its band gap decreases as the electric field increases.this website
