Aims: Identify the correlation between systolic and diastolic blood pressure measurement with digital arm and wrist baumanometers in young adults aged 18 to 40 at the Public University of Celaya, Guanajuato, Mexico.
Study Design: Observational, analytical, quantitative, correlational, diagnostics.
Place of Study: Public University of Celaya, Guanajuato, Mexico.
Methodology: We included 397 participants of an age range between 18 and 40 years; which 287 were women and 110 were men; with an average weight of 65.28 ± 15.08, and of stature 1.63 ± 0.09. Two types of digital, wrist and arm baumanometers were used to measure the systolic and diastolic blood pressure to observe the effectiveness of the values recorded during the measurement.
Results: The correlation between the 3 measurements of the systolic blood pressure was repeated in the first and third measurements (r = 0.46) and varied in the second (r = 0.39), in all three the value recorded by the highest arm baumanometer was found. In the 3 measurements of the diastolic blood pressure the correlation varied (r = 0.54, r = 0.50, r = 0.59); registering the highest value in the measurement with the arm baumanometer.
Conclusion: The correlation between the measurements with the baumanometers was not perfect, however it was good, it was considered that the measurement of blood pressure with the wrist baumanometer should be done with the wrist at the level of the heart; as well as movements of arm, hand or fingers will alter the result.

Abstract
Plasmonics has been attracting considerable interest as it allows localization of light at nanoscale dimensions. A breakthrough in integrated nanophotonics can be obtained by fabricating plasmonic functional materials. In particular, magneto‐optical materials are appealing as they may provide ultrafast control of laser light and surface plasmons via an external magnetic field. In this article, we demonstrate that it provides a significant enhancement of magneto‐optical effects as proved by increase in the intensity and polarization rotation effects by several orders of magnitude. Plasmonic structures can be operated in transmission, so that it may be implemented in devices for telecommunication, plasmonic circuitry, magnetic field sensing, and all‐optical magnetic data storage.
GaN‐On‐Si Epitaxy
Authors: Dadgar Armin 
Published: August 2019

AbstractThe wide‐bandgap semiconductor GaN is the enabler for light emitters in the visible to UV spectrum and for energy‐efficient high‐frequency and high‐power electronics. Due to the lack of GaN homosubstrates, GaN is mostly grown on heterosubstrates as sapphire, Si, or SiC by molecular beam epitaxy or in industry by metalorganic chemical vapor‐phase epitaxy. With Si being a low‐cost substrate available in large diameters, low‐cost mass production of GaN devices, especially of GaN electronics, is favorable on silicon. This article summarizes the advantages and difficulties of GaN growth on silicon in general and briefly describes the application for LED and transistor device fabrication.
Theoretical Study of Ternary CoSP Semiconductor: A Candidate for Photovoltaic Applications
Authors: Houari Abdesalem , Benissad Fares 
Published: August 2019

AbstractThe electronic structure of pyrite‐type cobalt phosphosulfide (CoSP) is studied using density‐functional theory. The calculated band structure reveals the non‐magnetic semiconducting character of the compound. The electronic structure is described using the electronic band structure and the densities of states. A band gap of 1.14 eV is computed within standard GGA, a value which is enhanced using hybrid functional. It separates the upper part of the valence band dominated by Co‐3d‐t2g states from the lower part of the conduction band made exclusively of Co‐3d‐eg, above of which lie S‐3p and P‐3p ones. The obtained values are suitable for applications in solar cells, according to Shockley–Queisser theory of light‐to‐electric conversion efficiency. The origin of the larger CoSP band gap, with respect to the one of the promising FeS2 compound, is explained and the chemical bonding properties are addressed. A comparative picture is established where several similarities are found, suggesting that CoSP could be of great practical interest in photovoltaics.

Published: August 2019

AbstractAmmonia (NH3) production from electrochemical nitrogen (N2) reduction reaction (NRR) under ambient conditions represents a sustainable alternative to the traditional Haber–Bosch process. However, the conventional electrocatalytic NRR process often suffers from low selectivity (competition with the hydrogen evolution reaction (HER)) and electron transfer bottleneck for efficient activation and dissociation. Herein, a strategy to simultaneously promote selectivity and activity through dual‐incorporation of Se and O elements onto the shell of HER‐inactive Te nanorods is reported. It is theoretically and experimentally verified that the exposure of lone‐pair electrons in the TeO2 shell of Se, O dual‐doped Te nanorods can maximize orbits overlap between N2 and Te for N‐N bond activation via π‐backdonation interactions. Further, the Gibbs free energy change indicates that the Lewis‐basic anchor ‐SeO ligand with strong electron‐donating characteristics serves as an electron reservoir and is capable of buffering the oxidation state variation of Te, thereby improving the thermodynamics of desorption of the intermediates in the N2‐to‐NH3 conversion process. As expected, a high faradaic efficiency of 24.56% and NH3 yield rate of ≈21.54 µg h−1 mg−1 are obtained under a low overpotential of ≈0.30 V versus reversible hydrogen electrode in an aqueous electrolyte under ambient conditions.
Optimizing Lectures From a Cognitive Load Perspective

Published: August 2019

AbstractLectures are a common instructional method in medical education. Understanding the cognitive processes and theories involved in learning is essential for lecturers to be effective. Cognitive load theory is one theory that is becoming increasingly recognized in medical education and addresses the appropriate use of one's working memory. Memory is essential to knowledge acquisition. Two types of memory can be considered, working memory (processing of information) and long‐term memory (storage of information). Working memory has a limited capacity. Cognitive load refers to the amount of information processing activity imposed on working memory and can be divided into three domains: intrinsic, extraneous, and germane. By attending to cognitive load, educators can promote learning. This paper highlights various ways of improving cognitive load for learners during lecture‐based instruction by minimizing extraneous load, optimizing intrinsic load, and promoting germane load.

Published: August 2019

BackgroundRhinovirus (RV) infections are the most common cause of viral upper respiratory infections (URIs), and in the majority of persons they are self‐limiting. However, in others, viral URIs can progress to bacterial sinusitis and induce chronic rhinosinusitis (CRS) exacerbations.MethodsWe conducted a comprehensive Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) review through April 2018 based on MEDLINE, EMBASE, Web of Science–Science Citation Index (SCI), and Conference Proceedings Citation Index‐ Science (CPCI‐S) using keywords: RV, respiratory virus, sinusitis, and airway epithelial cells. The goal of this systematic review was to: (1) determine the prevalence between RV and CRS, (2) study the changes that occur after experimental RV inoculation, (3) investigate the pathophysiologic mechanisms by which RV induces sinonasal inflammation, and (4) explore the treatment options available for RV‐associated sinusitis. Data regarding study design, research question, intervention, subjects, outcomes, and biases was extracted.ResultsThe initial search yielded 2395 unique abstracts, of which 614 were selected for full‐text review; 147 were included in the final review. We determined that (1) the prevalence of RV infections is increased in those with CRS, (2) humans challenged in vivo with RV secrete local inflammatory mediators with radiographic mucosal thickening, (3) RV species RV‐A and RV‐C challenges in vitro to sinonasal epithelia produce robust cytokine responses and differential gene changes, and (4) no current therapies have produced consistent and significant resolution of disease.ConclusionRV infections are common in persons with CRS, and incite inflammatory reactions that may result in CRS exacerbations and progression of disease. Further studies assessing RV species, and the host‐virome response are required to develop new strategies targeting RV‐induced CRS.

AimThe hemoglobin index (HbI) represents the amount of hemoglobin, which reflects regional tissue blood volume. The HbI is calculated in real time by a regional oxygen saturation (rSO2) monitor. For the hypothesis of our HbI project, we theorized that HbI could be a new method for the screening of subarachnoid hemorrhage (SAH) in overcrowded emergency departments. As a first step, this study aimed to clarify the effectiveness of HbI in screening SAH in out‐of‐hospital cardiopulmonary arrest (OHCA) patients using the rSO2 data of our previous studies.MethodsIn this single‐center, retrospective, observational study, we examined HbI in patients with OHCA transferred to the Trauma and Acute Critical Care Center at Osaka University Hospital (Osaka, Japan) during the period between April 2013 and December 2015. A sensor attached to the patient's forehead monitored HbI continuously.ResultsAmong 63 patients (40 men and 23 women; mean age, 76 [interquartile range (IQR), 66–85] years) with OHCA, five were diagnosed as having SAH (SAH group) and 58 were not (non‐SAH group). The HbI values were significantly higher in the SAH group than in the non‐SAH group (1.35 [IQR: 0.80–2.69] versus 0.41 [IQR: 0.32–0.61]), P = 0.0042). In the SAH group, with an HbI cut‐off value of 1.18, the specificity and sensitivity were 96% and 80%, respectively, and the area under the receiver operating characteristic curve of HbI was 0.89.ConclusionsThe HbI might be useful for the screening of SAH in patients with OHCA. The application of HbI in the emergency department could be expected in the future.

AbstractThe ever‐increasing demand for rechargeable batteries induces significant pressure on the worldwide metal supply, depleting resources and increasing costs and environmental concerns. In this context, developing the chemistry of anion‐inserting electrode organic materials could promote the fabrication of molecular (metal‐free) rechargeable batteries. However, few examples have been reported because little effort has been made to develop such anionic‐ion batteries. Here we show the design of two anionic host electrode materials based on the N‐substituted salts of azaaromatics (zwitterions). A combination of NMR, EDS, FTIR spectroscopies coupled with thermal analyses and single‐crystal XRD allowed a thorough structural and chemical characterization of the compounds. Thanks to a reversible electrochemical activity located at an average potential of 2.2 V vs. Li+/Li, the coupling with dilithium 2,5‐(dianilino)terephthalate (Li2DAnT) as the positive electrode enabled the fabrication of the first all‐organic anionic rechargeable batteries based on crystallized host electrode materials capable of delivering a specific capacity of ≈27 mAh/gelectrodes with a stable cycling over dozens of cycles (≈24 Wh/kgelectrodes).

Published: August 2019

AbstractIntroductionThe neutrophil‐to‐lymphocyte ratio (NLR) has been shown to be a marker associated with inflammation and is independently associated with the adverse clinical outcomes of symptomatic intracranial hemorrhage, cancer, and cardiovascular disease. Hemorrhagic transformation (HT) is a serious complication of ischemic cerebral infarction and can be intensified by therapeutic interventions for acute ischemic stroke (AIS). The purpose of our research was to explore the predictive effect of NLR for HT in patients with AIS and to determine the best predictive value.MethodsPubMed, Web of Science, EMBASE, MEDLINE, Cochrane, and Google Scholar were searched. The primary endpoint was HT, and subgroup analysis was performed. Review Manager software version 5.3 was used to statistically analyze the outcomes.ResultsA total of seven studies including 3,726 patients met the inclusion criteria. The pooled odds ratio (OR) value of the high NLR that predicted HT in AIS patients was 1.53 (95% CI, 1.21–1.92; p = .0003). In addition, 1.10 (95% CI, 1.05–1.15; p < .0001) was the pooled OR of the high NLR associated with increased 3‐month mortality in patients with AIS. In the subgroup analysis with an NLR cutoff value of 7.5–11, the correlation between NLR above the cutoff value and the rate of HT in patients with AIS was statistically significant (OR, 7.93; 95% CI, 2.25–27.95; p = .001).ConclusionA high NLR can predict HT and 3‐month mortality in patients with AIS. Regardless of the country of origin and the sampling time, an NLR with a cutoff value of 7.5–11 was independently associated with HT in AIS patients.

Published: August 2019

AbstractThis study aimed to develop a toolbox for kinematic and dynamic modeling and analysis of the high degree‐of‐freedom (DOF), redundant serial robots used widely in cooperative and space applications. With the Advanced Robotics Analysis Toolbox (ARAT), kinematic and dynamic modeling and analysis of the complex, high DOF, serial robots which may have universal, spherical, prismatic, or rotational joints with more than one DOF and a mobile or stationary base can be easily accomplished. The ARAT was used to design and analyze different complex structures of serial robots for robotic education students and robotics researchers who design and build exceptional new robots. The robot's kinematic and dynamic parameters including link lengths, directions, masses and inertias can be entered into the ARAT using a user‐friendly interface. Solid models of the robots can be created in a three dimensional (3D) environment for virtual reality simulations. In the ARAT, forward and inverse kinematic models, Jacobian matrix, trajectory planning, forward and inverse dynamic models can be produced in a computationally efficient way. All of the physical robot parameters such as angular and linear velocities, accelerations, forces, and torques at the joints, link origins and the center of mass of the links can be computed in 3D. The ARAT includes support for the most commonly used trajectory algorithms in serial robots, including polynomial, trigonometric (harmonic, cycloidal, elliptic), exponential, Gaussian, and Fourier‐based (Gutman, Freudenstein). These trajectories can be applied easily to each joint of the robots. To compare the kinematic and dynamic results obtained from ARAT and MATLAB‐Simscape Multibody simulation program, different structures of the serial robots were simulated in both programs. The results that produced from ARAT and MATLAB‐Simscape were similar. The ARAT is much better from the serial robot simulation toolboxes existing in literature in terms of computation capability, visual ability, and easy usage.

Structure–Activity Relationship of Iron Oxides for NO Reduction in the Presence of C3H6, CO, and O2
Authors: Ueda Kakuya , Ohyama Junya , Sawabe Kyoichi , Satsuma Atsushi 
Published: August 2019

AbstractSpinel‐type NiFe2O4 exhibited the highest NO reduction activity among base‐metal oxides under simulated exhaust of a gasoline‐powered vehicle. The structure–activity relationship of iron oxides has been investigated through both experimental and computational studies. Spinel iron oxide (γ‐Fe2O3) exhibited a much higher NO reduction activity than that of iron oxide with other structures (α‐Fe2O3 and LaFeO3). Operando IR measurements clarified that the spinel structure facilitated the reaction between NOx and adsorbed oxidized hydrocarbon or cyanide species. The high reactivity of the spinel structure was ascribed to the high adsorption energy of NO, as elucidated by DFT calculations. Furthermore, molecular orbital calculations demonstrated that the local coordination structure of the spinel iron oxide induced the involvement of not only σ but also π orbitals during NO adsorption on Fe atoms. This work clarified the origin of the structure‐dependent activity of metal oxides, with a focus on their local coordination structures.
