The scalability of different file‐sharing methods
Authors: Bergman Ofer , Israeli Tamar , Whittaker Steve 
Published: March 2020

AbstractFile sharing is an integral component of modern work. Files can be shared either using Group Information Management (GIM), where collaborators exploit a common repository (e.g., the cloud), or Personal Information Management (PIM), where files are sent via email attachments, and collaborators store files individually in personal collections. Given the recent prevalence of GIM, we compare the effects on retrieval for PIM versus GIM collections. We examine the effects of various theoretically motivated factors relating to collection size, properties of the target file, and user workload. In our study, 289 participants accessed 1,557 of their own shared files in a naturalistic setting. Results indicate that factors relating to collection size, file versions, and user workload negatively affect the retrieval of GIM more than PIM files, indicating that PIM is more scalable than GIM. Testing a very different population, we confirm previous findings that failure percentages of GIM are approximately double those of PIM. We discuss possible theoretical explanations, specifically how factors that hinder retrieval exacerbate the general GIM problem of retrieving files organized by other people. Overall, PIM's greater scalability has practical implications for fast‐growing organizations such as startups when choosing their sharing policies.

AbstractAn attempt was made to determine the ground state and excited state dipole moments and quantum chemical computations of two coumarin compounds, namely 3‐hydroxy‐3‐[2‐oxo‐2‐(2‐oxo‐2H‐chromen‐3‐yl)‐ethyl]‐1,3‐dihydro‐indol‐2‐one (3HOCE) and 3‐[2‐(8‐methoxy‐2‐oxo‐2H‐chromen‐3‐yl)‐2‐oxo‐ethylidene]‐1,3‐dihydro‐indol‐2‐one (3MOCE). Both compounds displayed a red shift with enhancement in solvent polarity. The larger excited state dipole moment indicated the more polar nature of the selected compounds in the excited state than in the ground state. Kinetic stability and chemical reactivity of the selected compounds were studied with help of the quantum chemical properties of the compounds such as frontier molecular orbital analysis using density functional theory calculations with B3LYP/6–311+G (d, p) basis sets. Molecular electrostatic potential, Mulliken charges, natural bond orbital, and nonlinear optical properties were further studied. NBO analysis showed proton transfer within the selected donor–acceptor, depicting the large energy of stabilization for the compounds. The calculated Fukui function inferred the local softness and electrophilicity indices of used solute compounds.

AbstractBackground and objectivesThe effects of gluten on rheological properties of dough and qualities of noodles with potato–wheat formulated flour blends were investigated with the objective of developing and optimizing formulation.FindingsUsing a formulated flour with potato mass ratio of 30% as the base flour and varying gluten addition, it was shown that addition of wheat gluten at levels of 7.0%–9.0% not only improved rheological properties of the formulated flour, but also improved the textural properties of noodles. The effects of the water and salt on the qualities of noodles were also investigated. The L9(34) orthogonal design results showed that the optimal noodle formulation was wheat gluten level of 8.0%, salt level of 4.0%, and water level of 47.0%, giving a cooked broken rate of 2.10% and sensory score of 88.6.ConclusionsFor the base flour of potato/wheat 30:70, wheat gluten addition of 7.0%–9.0% improved farinograph and extensograph properties as well as textural properties. The optimal formulation of noodles was potato flour level of 30%, wheat flour level of 70%, wheat gluten level of 8.0%, salt level of 4.0%, and water level of 47.0%.Significance and noveltyGluten has been used to improve rheological properties of dough and qualities of noodles with potato–wheat flour blends.

Electrodeposition of Zinc from Alkaline Electrolytes Containing Quaternary Ammonium Salts and Ionomers: Impact of Cathodic‐Anodic Cycling Conditions
Authors: Rossi Francesca , Mele Claudio , Boniardi Marco , Bozzini Benedetto 
Published: March 2020

AbstractDendrite suppression capabilities are key factors for the practical deployment of rechargeable Zn‐based batteries. We propose a systematic electrochemical investigation, accompanied by SEM imaging, of the impact of representative quaternary ammonium (QA) salts and ionomers on Zn electrodeposition. Both cathodic and anodic processes were considered, because insoluble corrosion products can impact subsequent electrodeposition during cycling. We used simple cyclic voltammetry methods and developed a framework for their quantitative interpretation in terms of physically legible descriptors. QA‐based additives tend to suppress the accumulation of anodic products, favoring symmetric cathodic and anodic activation. Poly di‐allyl di‐methyl ammonium chloride (PDADMAC), a polymer with limited cathodic reactivity, was found to be a promising additive that minimizes cathodic and anodic irreversibility and stabilizes mass transport, possibly owing to the formation of a single‐ion conducting cathodic film.
Comparison of integrated natural sciences and specialized chemistry classes – a study on the interest of students and their perceived self‐efficacy in chemical contents

Published: March 2020

AbstractDem Fach Naturwissenschaften, in welchem die Fachgrenzen der drei naturwissenschaftlichen Disziplinen Biologie, Chemie und Physik aufgelöst und naturwissenschaftliche Lerninhalte fächervernetzend unterrichtet werden, wird ein großes Potential zugesprochen. Beispielsweise soll durch den Fächerverbund ein gendergerechterer Unterricht und die Einbindung sinnstiftender Alltagskontexte in den Unterricht besser möglich sein. Es gibt jedoch nur wenige empirische Studien, die die beiden Unterrichtsformen Fachunterricht Chemie und integrierter Naturwissenschaftsunterricht miteinander vergleichen und somit untersuchen, inwieweit das Fach Naturwissenschaften die ihm zugesprochenen Potentiale ausschöpfen kann. Vorgestellt wird eine Studie, in der Schülerinnen und Schüler der Sekundarstufe I (N=509) nach ihrem Interesse an chemischen Inhalten, Kontexten und Tätigkeiten sowie fachinhaltsbezogenen Selbstwirksamkeitserwartungen befragt wurden.
Bioorthogonal Phosphorogenic Rhenium(I) Polypyridine Sydnone Complexes for Specific Lysosome Labeling
Authors: Shum Justin , Zhang Pei‐Zhi , Lee Lawrence Cho‐Cheung , Lo Kenneth Kam‐Wing 
Published: March 2020

AbstractMany novel bioorthogonal reactions have been developed for labeling, such as the strain‐promoted sydnone‐alkyne cycloaddition (SPSAC), but sydnone‐based probes with phosphorogenicity (i. e., phosphorescence turn‐on upon reaction) have not been investigated to date. Herein, we report the synthesis, characterization, and photophysical properties of rhenium(I) polypyridine complexes containing a sydnone moiety as bioorthogonal phosphorogenic probes. Their reactions with strained alkyne derivatives and the associated photophysical changes were examined. Upon SPSAC with bicyclo[6.1.0]non‐4‐yn‐9‐ylmethanol (BCN‐OH), the complexes exhibited emission enhancement in the range of 8.8 to 17.3. Importantly, conjugation of the complexes with BCN‐modified bovine serum albumin (BCN‐BSA) led to the increase in emission enhancement to as high as 38.9 and extended lifetimes in the range of 1.80 to 4.71 μs. Additionally, the bioorthogonal ligation of one of the complexes with a morpholine derivative was shown to induce specific lysosomal labeling in live cells; colocalization studies with LysoTracker Deep Red indicated a Pearson's coefficient of 0.83.
How significant is corporate social responsibility to business research?

Published: March 2020

AbstractPrevious studies have established that there is a positive evolution of the quantity of corporate social responsibility (CSR) research output in terms of published papers. So far, however, there has been little discussion about how influential it has become within the business discipline. This article seeks to obtain data which will help to address this research gap. The databases Web of Science and Journal Citation Reports (JCR) were used to carry out analyses at the journal and article levels. Results confirmed a solid growth in CSR research and revealed that papers on the topic have gained attention from the scientific community. Furthermore, CSR articles are mostly concentrated in a small number of specialized journals, and opting for these journals may be related to the total citations. The conclusions drawn from this study may be especially useful for academic managers and business researchers interested in the evaluation of academic performance.
Kinetically Controllable Hydrogen Generation at Low Temperatures by the Alcoholysis of CaMg2‐Based Materials in Tailored Solutions

Published: March 2020

AbstractThe alcoholysis of CaMg2‐based materials for hydrogen generation is reported. Compared to hydrolysis in water, hydrogen supply from alcoholysis shows an excellent potential for outdoor applications, which not only bypasses the formation of passivation layers deposited on the surface of particles but also breaks the temperature bottleneck in which hydrolysis occurs over 0 °C. To remove the troublesome freezing issue of the water solution system in low‐temperature conditions, here, instead of pure methanol, methanol/water and methanol/ethanol solutions are applied to react with CaMg2 alloy (CM2) and its hydrides (H‐CM2) for hydrogen generation. Compared with pure water and ethanol, the reaction of CaMg2‐based materials with methanol possesses much faster reaction kinetics and gives a considerable hydrogen yield. CM2 can generate 858 mL
g−1 within only 3 min at room temperature as it reacts vigorously with methanol, as opposed to a low hydrogen yield with ethanol and water (395 and 224 mL
g−1 within 180 min, respectively) under the same conditions. Even at −20 °C, there is still over 600 mL
g−1 released at a conversion rate of 70.7 % within 100 min for methanolysis, which shows its prominent advantage for hydrogen production, especially in winter or subzero areas. Interestingly, the methanolysis byproducts can transform into metal hydroxides and methanol in the reaction with water, and the methanol may be separated and reused as an intermediate. Moreover, the hydrogen behavior of CaMg2 methanolysis can be well controlled by tailoring the components of the solutions to deliver a promising hydrogen supply system for the hydrogen economy.

AbstractPopulation connectivity is driven by individual dispersal potential and modulated by natal philopatry. In seabirds, high vagility facilitates dispersal yet philopatry is also common, with foraging area overlap often correlated with population connectivity. We assess the interplay between these processes by studying past and current connectivity and foraging niche overlap among southern rockhopper penguin colonies of the coast of southern South America using genomic and stable isotope analyses. We found two distinct genetic clusters and detected low admixture between northern and southern colonies. Stable isotope analysis indicated niche variability between colonies, with Malvinas/Falklands colonies encompassing the species entire isotopic foraging niche, while the remaining colonies had smaller, nonoverlapping niches. A recently founded colony in continental Patagonia differed in isotopic niche width and position with Malvinas/Falklands colonies, its genetically identified founder population, suggesting the exploitation of novel foraging areas and/or prey items. Additionally, dispersing individuals found dead across the Patagonian shore in an unusual mortality event were also assigned to the northern cluster, suggesting northern individuals reach southern localities, but do not breed in these colonies. Facilitated by variability in foraging strategies, and especially during unfavorable conditions, the number of dispersing individuals may increase and enhance the probability of founding new colonies. Metapopulation demographic dynamics in seabirds should account for interannual variability in dispersal behavior and pay special attention to extreme climatic events, classically related to negative effects on population trends.

AbstractAimsAlthough left ventricular ejection fraction (LVEF) is routinely used to categorize patients with heart failure (HF), whether it predicts outcomes after hospitalization for acute heart failure (AHF) is uncertain. Consequently, we assessed the relationship between LVEF and cardiovascular (CV) outcomes in a large, well characterized cohort of patients hospitalized for
AHF.Methods and resultsThe 6128 patients from the RELAX‐AHF‐2 trial who had LVEF measured during AHF hospitalization were separated into LVEF quartiles and the relationship between LVEF and a composite of CV mortality and rehospitalization for HF or renal failure through 180 days was assessed. We found progressively lower risk for this composite outcome as LVEF increased (hazard ratio 0.95, 95% confidence interval 0.93–0.98 per 5% LVEF increase, P < 0.001) that was driven predominantly by decreased risk for rehospitalization. The smoothed spline curve depicting risk remained stable as LVEF decreased until reaching approximately 40%, at which point risk increased progressively with further reductions in LVEF. Significant differences between LVEF quartiles for post‐discharge CV risk were seen in patients with an ischaemic aetiology or with a history of HF preceding index hospitalization, but were less robust in patients with non‐ischaemic aetiology and absent in those with de novo
HF.ConclusionIn patients hospitalized with AHF, CV events over 180 days were more frequent in patients with lower LVEF. This was due predominantly to a significant increase in risk for HF/renal failure rehospitalization but not in either CV or all‐cause mortality. LVEF had greater prognostic value in patients with ischaemic aetiology or pre‐existing
HF.
CR‐QRM‐MLD for SD‐SM Hybrid MIMO systems

Published: March 2020

AbstractRecently, multiple‐input multiple‐output (MIMO) is studied actively such as a key technology for wireless communications. Space division (SD) multiplexing and spatial modulation (SM) have been proposed as the transmission technique of MIMO systems. In the full maximum likelihood detection (MLD), the QR decomposition with M‐algorithm MLD (QRM‐MLD), and the channel ranking QRM‐MLD (CR‐QRM‐MLD) for the SD‐MIMO, there are the trade‐off between the system performance and the computational complexity. Also, in the SM‐MIMO, the transmission rate is deteriorated due to a small number of transmitted signals. To solve these problems, in this article, we propose the CR‐QRM‐MLD for SD‐SM Hybrid MIMO (SD‐SM‐MIMO) systems. From the computer simulation results, the proposed method shows the reduction of the computational complexity and the good bit error rate performance.

AbstractBackgroundSingle‐modality treatment (surgery or radiotherapy [RT]) is a curative treatment option for early‐stage oropharyngeal carcinoma (OPC) with comparable (excellent) oncological outcomes. This study aimed to compare self‐reported swallowing function.MethodsParticipants with a T1‐2N0‐2bM0 OPC who were offered single‐modality treatment and were recruited to the Head and Neck 5000 study were included. Prospectively collected self‐reported swallowing function was compared between surgery and RT.ResultsThose offered RT (n = 150) had less favorable baseline characteristics than those offered surgery (n = 150). At 12‐month follow up, RT participants reported more swallowing problems (35% vs 23%, RR 1.3; 95% CI 0.8‐2.3, P = .277) in models adjusted for baseline characteristics. In those allocated to surgery who received adjuvant therapy (n = 78, 52%), the proportion with swallowing problems was similar to those allocated to RT alone.ConclusionsParticipants offered surgery alone had similar mortality but improved swallowing, although this was not statistically significant. However, over half of participants offered surgery alone received surgery and adjuvant therapy.

AbstractRaman spectroscopy was employed as a nondestructive technique for the analysis of dry traces of oral fluid to differentiate between smoker and nonsmoker donors with the aid of advanced statistical tools. A genetic algorithm (GA) was used to determine eight spectral regions that contribute the most to the differentiation of smokers and nonsmokers. Thereafter, a classification model was developed based on the artificial neural network (ANN) that showed 100% accuracy after external validation.

A simple method for rapid calibration of faraday and ion‐counting detectors on movable multicollector mass spectrometers
Authors: Davis Donald W. 
Published: March 2020

AbstractMethods are presented for rapid determination of relative efficiencies of Faraday cups in a multicollector array with movable cups and of Daly or electron multiplier detector dead time and gain values. The Faraday calibration approach is based on measuring the same isotopic ratio in two sequences with different collector configurations having one collector in common. Changes in thermal fractionation during the two measurement sequences are monitored using the same two collectors. Since the relative efficiencies are determined by measuring the same ratio in different cups corrected for time‐dependent changes in fractionation, it is unnecessary to use a standard of known composition and calculations are simple, not requiring the solution of multiple equations. Determination of dead time and gain values for a Daly detector are shown based on multidynamic measurements of masses 207, 206, and 208 from Pb standard SRM982 in two sequences consisting of L1‐Daly‐H1 and Daly‐H1‐H2. This provides two equations that can be solved for Daly dead time and gain. This method uses static measurements and is therefore insensitive to signal instability. It also does not require use of a standard of known isotopic composition. The potential of using known cup efficiencies to help determine absolute isotopic abundances is discussed.

Authors: Mou Jin‐Chao , Wu Di‐Si , Li Yuan Chun 
Published: March 2020

AbstractThis letter presents the electric and magnetic couplings modeling on CMOS 65 nm technology. It is based on the simplified equivalent substrate model. The field distribution is studied to analyze qualitatively the electric and magnetic couplings. Based on CMOS 65 nm technology, the coupling coefficients with and without passivation are calculated quantitatively for comparisons and then the coupling characteristics are summarized. In order to demonstrate the coupling model, a bandpass filter using electric and magnetic couplings is designed. The measured bandwidth is 23 GHz centered at 63.5 GHz and the insertion loss is 3.8 dB. Good agreement between the simulated and measured results validates the coupling modeling.
Meshless hybrid implicit‐explicit radial point interpolation method in scattering of dielectric particles by light beam with orbital angular momentum
Authors: Yu Zhong , Wang Yijing , Xie Yongbin 
Published: March 2020

AbstractThis letter proposes a meshless hybrid implicit‐explicit radial point interpolation method (HIE‐RPIM) to simulate the scattering of the Laguerre‐Gaussian beam with orbital angular momentum (OAM) by dielectric particles. The results are verified by comparison with the finite‐difference time domain (FDTD) and the radial point interpolation method (RPIM) which shows that the HIE‐RPIM agrees well with the FDTD, and the HIE‐RPIM is about 4.9 times faster than the FDTD method and about 4.2 times faster than the RPIM. Moreover, the scattering angle of forward scattering intensity maximum is about 10° to 35° when the OAM modes are L = 1 and 2 and moves back by 5° to 15° from L = 1 to 2. The HIE‐RPIM has potential to research the scattering properties of OAM beam.
