Theoretically studied MoB<sub>2</sub> monolayer detects NO<sub>2</sub> gas with fast recovery time.
While neck circumference (NC) is a useful predictor of obstructive sleep apnea (OSA) in adults, childhood OSA difficult to predict clinically. We utilized the circumference-height ratio (NHR) normalize NC growing children. Our study aimed determine if (1) reproducible clinical measurement; (2) NHR predicts children; (3) this metric translates adults.For retrospective study, paired measurements (from clinic and laboratory) 100 consecutive adult subjects were used confirm inter-observer...
The discovery of superconductivity in Sr-doped ${\mathrm{NdNiO}}_{2}$ is a crucial breakthrough the long pursuit for nickel oxide materials with electronic and magnetic properties similar to those cuprates. infinite-layer member family square-planar nickelates general chemical formula ${\mathrm{R}}_{n+1}{\mathrm{Ni}}_{n}{\mathrm{O}}_{2n+2}$ (R = La, Pr, Nd, $n=2,3,...\ensuremath{\infty}$). In this Rapid Communication, we investigate trilayer series...
The recent discovery of high-${T}_{c}$ superconductivity in Sr-doped ${\mathrm{NdNiO}}_{2}$ has sparked a renewed interest investigating nickelates as cuprate counterparts. Parent cuprates $[{\mathrm{Cu}}^{2+}:{d}^{9}]$ are antiferromagnetic charge transfer insulators with the involvement single ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$ band around Fermi level and strong $p\text{\ensuremath{-}}d$ hybridization. In contrast, isoelectronic $[{\mathrm{Ni}}^{+}:{d}^{9}]$ is metallic self-doped by...
The absence of a selection rule coupling oppositely circularly polarized light to conjugate valleys, the basis "lightwave valleytronics", would appear curtail possibilities graphene as valleytronic platform. Here we show that combining linearly THz and infrared allows not only near perfect valley charge polarization but also complete control over associated current. underlying mechanism involves induced momentum space shift uncontrasted generated by component, yielding at K Γ points. Ab...
This preliminary study investigated the tolerability and efficacy of a novel mattress technology-the Sound-To-Sleep (STS) system-in treatment sleep problems in children with autism.After screening, 45 children, ages 2.5 to 12.9 years, were randomized order technology use (On-Off vs. Off-On). Treatment conditions (On Off) lasted two weeks immediate crossover. Tolerability, including discontinuation parent-report tolerance ease use, was tracked throughout study. Efficacy assessments obtained...
Children with Down syndrome (DS) commonly have obstructive sleep apnea (OSAS) and may assume a unique sleeping position not systematically described previously. We describe this in DS explore its relationship OSAS comparison to control children (CC).Overnight video-polysomnograms (PSG) of consecutive (age 2-18 y), referred our center between April 2008 October 2009, were retrospectively analyzed by single scorer (ES). CC group comprised age gender matched, non-syndromic, neurologically...
<h3>Objectives</h3>To identify the prevalence of clinically relevant findings during cardiac evaluations pediatric patients with obstructive sleep apnea (OSA) undergoing adenotonsillectomy (TA), and to determine association between postoperative respiratory complications.<h3>Design</h3>Retrospective medical chart review.<h3>Patients</h3>Pediatric aged 10 months 15 years who underwent both echocardiography polysomnography (PSG) within 6 prior TA for OSA from April 2007 through 2011.<h3>Main...
Recent experimental measurements on the layered triangular-lattice antiferromagnet ${\mathrm{EuCd}}_{2}{\mathrm{As}}_{2}$ have revealed an interesting interplay among magnetism, charge transport, and optical properties. To explore nature of interaction these degrees freedom, electronic structure, magnetic properties, electrical properties are investigated using density functional theory Boltzmann transport under various approximations such as generalized gradient approximation (GGA),...
Study Objectives: Caffeine, a commonly consumed psychoactive substance, can have signifi cant effects on sleep.Caffeine intake among children is increasing, mainly in the form of sodas.However, adolescent caffeine consumers may lack knowledge about content common beverages.If true, this very fact hamper assessment consumption sleep if such assessments are priori dependent responders being able to reliably distinguish between caffeinated and noncaffeinated beverages.This preliminary study...
We present a first-principles scheme for incorporating many-body interactions into the unified description of quadratic optical response to light noncentrosymmetric crystals. The proposed method is based on time-dependent current-density theory and includes electron-hole attraction via tensorial long-range exchange-correlation kernel, which we calculate using parameter-free bootstrap approximation. By bridging with Wannier-interpolation independent-particle transition matrix elements,...
A new multisensor (i.e. resistive and magnetic) CrI3-WTe2 heterostructure (HS) to detect the toxic gases BrF3 COCl2 (Phosgene) has been theoretically studied in our present investigation. The HS demonstrated sensitivity towards both by varying its electronic magnetic properties when gas molecule interacts with HS. Fast recovery time (<0.14 fs) under UV radiation observed. We have considered two configurations of adsorbed HS; (1) F ion (C1) (2) Br (C2). In C1 case adsorption energy Ead is...
We study the similarities and differences in shift photocurrent contribution to bulk photovoltaic effect between transition-metal dichalcogenide monolayers nanotubes. Our analysis is based on density functional theory combination with Wannier interpolation technique for calculation of photoconductivity tensor. results show that nanotube radii practical interest $r>60$~\AA, a single-wall well described by monolayer. Additionally, we quantify generated under realistic experimental conditions...
Capturing the non-collinear magnetic ground state of spinel vanadates AV$_2$O$_4$ (A= Mn, Fe and Co) remains an outstanding challenge for state-of-the-art ab-initio methods. We demonstrate that both spin texture, as well magnitude local moments, are captured by a single value on-site Hubbard $U$ 2.7~eV in conjunction with density approximation (LSDA+$U$), provided source term (i.e., monopole term) is removed from exchange-correlation field ${\bf B}_{XC}$. further structure B}_{XC}$ highly...
Abstract The coupling of circularly polarized light to local band structure extrema ("valleys”) in two dimensional semiconductors promises a new electronics based on the valley degree freedom. Such pulses, however, couple only charge and not current, precluding lightwave manipulation this second vital element valleytronic devices. Contradicting established wisdom, we show that few cycle limit is imbued with an emergent vectorial character allows direct current. underlying physical mechanism...
