Such a combination of semiconductor heterojunction and semiconductor-metal Schottky contact presents a new strategy to design high performance electrical sensors with high sensitivity, stability, selectivity, and wide operation temperature window, which are potentially suitable for advanced energy systems such as automotive engines and power plants. © 2020 IOP Publishing Ltd.Recently, the arsenic monolayer has been successfully fabricated by micromechanical stripping. However, it is a non-magnetic semiconductor, including its derivatives. Here, we theoretically explore how to induce magnetism for arsenene armchair nanotubes (AsANTs) with a low-concentration TM (TM=Co, Y, Rh, Ni, Mo, Ru) atom doping, especially focusing on their structural stability, magneto-electronic property, carrier mobility, and the strain effects. The high stability of these doped tubes are confirmed by the calculated binding energy and formation energy as well as Forcite annealing molecular dynamics simulations. The AsANT can act as band-gap narrowed non-magnetic semiconductors or highly spin-polarized magnetic semiconductors (half- semiconductor or bipolar magnetic semiconductor) depending on TM types, suggesting different promising applications, such as developing infrared photodetectors with broadband detectionin or spintronic devices. The magnetic thermal stability beyond the room temperature is predicted for doped tubes. Furthermore, the carrier mobility of AsANTs can be tuned into a wide region by TM doping, but it is enhanced in most of cases. The carrier polarity and spin polarity of mobility can also clearly observed. Particularly, the applied strain can induce the rich magnetic phase transition among a half-semiconductor, half-metal, bipolar magnetic semiconductor, and nonmagnetic state, as well as the presented stepwise change of total magnetic moment between high magnetized and nonmagnetic states is highly desirable for engineering a mechanical switch, which can reversibly work between magnetism and demagnetism to control spin-polarized transport by applying strain. © 2020 IOP Publishing Ltd.The purpose of this study was to evaluate whether the complexity of corneal pulse (CP) signal differentiates primary open-angle glaucoma (POAG) patients from healthy subjects. The study sample consisted of 28 POAG patients and a control, age-matched group of 30 subjects. After standard ophthalmic examination, the CP signal of a randomly selected eye of each participant was measured using a non-contact ultrasonic micro-displacement measurement technology.  https://www.selleckchem.com/products/rvx-208.html  After preprocessing, the complexity of CP signals was estimated using the refined composite multiscale fuzzy entropy (RCMFE) up to a scale factor No. 50. The average values of RCMFE were computed from three repeated measurements of the CP signals for each participant and each scale factor. Complexity of the CP signal in glaucomatous eyes was higher than that observed in healthy ones. Also, RCMFE of the CP signal was found to statistically significantly differentiate between the two groups for scales in the range from 26 to 43. For these scales, the one for which the lowestp-value (t-test;p= 0.017) was obtained when comparing RCMFE between the two groups was selected as the optimal scale. Next, a receiver operating characteristic analysis for the optimal scale showed that the proposed approach of calculating the multiscale entropy of the CP signal has some potential to discriminate between POAG patients and healthy controls (sensitivity, specificity, and accuracy of 0.643, 0.700, and 0.672, respectively). In conclusion, RCMFE, as a complexity measure, may be considered an auxiliary indicator supporting glaucoma diagnostics. © 2020 Institute of Physics and Engineering in Medicine.\textitObjective- The main objective of this research was to study the coupling between neural circuits and the vascular network in the cortex of small rodents from system engineering point of view and generate a mathematical model for the dynamics of neurovascular coupling. The model was adopted to implement closed-loop blood flow control algorithms. \textitApproach- We used a combination of advanced technologies including optogenetics, electrocorticography, and optical coherence tomography to stimulate selected populations of neurons and simultaneously record induced electrocorticography and hemodynamic signals. We adopted system identification methods to analyze the acquired data and investigate the relation between optogenetic neural activation and consequential electrophysiology and blood flow responses. \textitMain Results- We showed that the developed model, once trained by the acquired data, could successfully regenerate subtle spatio-temporal features of evoked electrocorticography and cerebral blood flow responses following an onset of optogenetic stimulation. \textitSignificance- The long term goal of this research is to open a new line for computational analysis of neurovascular coupling particularly in pathologies where the normal process of blood flow regulation in the central nervous system is disrupted including Alzheimer's disease. © 2020 IOP Publishing Ltd.OBJECTIVE To assess whether the slopes of volumetric capnography differ in preterm compared to term-born ventilated newborn infants and whether they are related to gestational age and the duration of ventilation. APPROACH The slopes of phase II (SII) and III (SIII) of volumetric capnographs were measured in ventilated term and preterm infants at King's College Hospital NHS Foundation Trust. The correlations of the slopes with gestational age (GA), duration of invasive ventilation and fraction of inspired oxygen (FIO2) were assessed. The slopes were normalised by multiplying the results with the expiratory tidal volume (VT) measurement. MAIN RESULTS Fifty-six infants (44 preterm) were assessed. The preterm infants had a median (IQR) gestational age of 26 (25 - 29) weeks and were ventilated for 8 (3 - 32) days with a VT of 5.4 (4.1-6.8) ml/kg. The term infants had a gestational age of 39 (37 - 40) weeks and were ventilated for 1 (1 - 6) day with a VT of 4.0 (3.6-5.3) ml/kg. The SII [85.9 (76.2 - 98.4) mmHg] and SIII [16.
