Published: August 2020

AbstractIn the flexible electronics sector, there is an urgent need for higher performance, and hence, many new technologies are emerging in recent years. The field of organic and printed electronics allows low production costs and large areas. The silicon technology allows nanometric resolutions and better performance. A new technology CAD (TCAD)‐based design methodology is needed to combine both mechanical flexibility and high performance. This work presents a predictive TCAD calibration methodology for indium‐gallium‐zinc‐oxide thin‐film transistors (TFTs), employing physics‐based modeling to support and enhance simulation‐based device development. In this work, based on the nonlinear finite element technique, a TCAD framework has been developed to introduce different types of large deformations and obtain the local stress/strain profiles (mapping) inside the devices. The impacts of various kinds of deformations on the electrical characteristics of the strained TFTs are studied. The feasibility (via predictions) for amorphous‐indium‐gallium‐zinc‐oxide (a‐IGZO) TFTs, combining considerable mechanical flexibility, high electrical performance, and finally, excellent stability under deformation, may be useful for mechanical deformation‐aware design and modeling for highly flexible electronics. To the best of our knowledge, the highest cutoff frequency (fT > 690 MHz) possible for strain‐engineered a‐IGZO TFTs is predicted in entirely flexible technologies that can be used to realize active transceivers operating in the MHz regime.

Published: August 2020

AbstractUpconversion imaging, where mid‐infrared (IR) photons are converted to visible and near‐IR photons via a nonlinear crystal and detected on cheap and high‐performance silicon detectors, is an appealing method to address the limitations of thermal sensors that are expensive, often require cooling, and suffer from both limited spectral response and limited spatial resolution as well as poor sensitivity. However, phase matching severely limits the spectral bandwidth of this technique, therefore requiring serial acquisitions in order to cover a large spectrum. Here, a novel upconversion imaging scheme covering the mid‐IR based on adiabatic frequency conversion is introduced. The study presents mid‐IR multicolor imaging and demonstrates simultaneous imaging on a complementary metal–oxide–semiconductor (CMOS) camera of radiation spanning a spectrum from 2 to 4 µm. This approach being coherent and ultrafast in essence, spectrally resolved spatiotemporal imaging is further demonstrated that allows spatially distinguishing the temporal evolution of spectral components.
Choosing among alternative new product development projects: The role of heuristics

Published: August 2020

AbstractThe initial screening decision that marketing managers make is critical. It requires the selection of what innovation project to invest in, which is fundamental to marketing success. However, our knowledge of how managers make these decisions and how this impacts performance is limited. By drawing upon cognitive psychology and the managerial decision‐making literature, we address two critical questions. The first question focuses on identifying specific decision‐making types (e.g., specific heuristics, intuition) used when making an innovation screening decision. Based on this analysis and prior research, we develop specific decision‐maker profiles about how an individual manager decides. The second research question is about connecting these profiles with performance. Specifically, it addresses what the consequences of different decision‐maker profiles are on the perceived accuracy and speed of decision‐making? Data were collected from 122 senior managers in these industries. We find that when heuristics are used alone, or concurrently with intuition, managers make decisions that are as accurate as when they rely on analytical decision‐making. However, the process is significantly faster. The findings provide an important step toward a more comprehensive understanding of decision‐making at the front‐end of innovation.
Conventional Magnetic Resonance Imaging in the Diagnosis of Parkinsonian Disorders: AMeta‐Analysis
Authors: Lee Will 
Published: August 2020

ABSTRACTBackgroundNumerous conventional magnetic resonance imaging (cMRI) parameters were previously found to differentiate parkinsonian disorders with statistical significance, but effect size has not been considered.ObjectivesTo quantify effect size of previously identified cMRI parameters that differentiated parkinsonian disorders with statistical significance.MethodA PubMed search limited to studies assessing cMRI parameters in at least 2 of Parkinson's disease, progressive supranuclear palsy, multiple system atrophy, and corticobasal degeneration/syndrome were selected. Either Cohen's d or positive and negative likelihood (LR+/−) as well as diagnostic odds ratios (DORs) were calculated as appropriate. cMRI parameter was considered useful if Cohen's d > 1.94 (<20% overlap) or if LR+ > 10, LR− < 0.1, or DOR > 20.ResultsLiterature search identified 8848 publications and 36 were included for analysis. Putaminal (Cohen's d 2.07; DOR 23–infinity), pontine (DOR 32–infinity), and middle cerebellar peduncle (Cohen's d 2.24; DOR infinity) abnormalities were most useful in differentiating multiple system atrophy while reduced midbrain (Cohen's d 2.33–8.69; DOR infinity) and superior cerebellar peduncle (Cohen's d 2.47; DOR 51–infinity) diameters separated progressive supranuclear palsy. Corticobasal degeneration/syndrome does not have any distinguishing cMRI features, but reduced midbrain diameter may help differentiate corticobasal degeneration/syndrome from Parkinson's disease (DOR infinity). When LR− was calculated, all of these features carried a value of <0.1.ConclusionA number of cMRI features consistently demonstrated large effect size in separating parkinsonian disorders. However, it is the presence and not absence of these cMRI features that is most useful in patients with low to moderate pretest probability.

Published: August 2020

AbstractA radio frequency chamber for rapid food thawing is presented. The proposed chamber is mainly composed of an aluminum shell, a plastic tray, and two metal cylinders with two metal disks located in the top and bottom of the chamber. The size of the thawing chamber is 300 × 300 × 230 mm. The proposed chamber resonates at a frequency of 433 MHz. The influences of the size of the frozen models and the chamber structure on the resonant frequency are analyzed. The simulated electric field of the chamber is distributed evenly and concentrated. Experimental results demonstrate that the proposed chamber can provide a fast and uniform thawing effect compared with the other three current methods.

AbstractVarious types of next‐generation encapsulation films based on polyolefins have recently been introduced and could attract market attention. These material innovations can be classified as polyolefin elastomer (POE) and thermoplastic polyolefin (TPO) encapsulants, both of which consist of a polyethylene backbone with different side groups. The main advantage of these materials is the replacement of the vinyl acetate side groups of state‐of‐the‐art encapsulant ethylene vinyl acetate (EVA) so that acetic acid cannot be formed. The main objective of this paper is to investigate the material properties of next‐generation encapsulant films and compare them to an EVA reference. Two commercially available EVA alternatives (POE and TPO) have been selected. The material properties of single films as well as the electrical performance of test modules using these different encapsulants were investigated. The different films show comparable optical, thermal and thermo‐mechanical properties, with slight differences in UV transparency and melting temperatures. Only shear viscosity values are higher for TPO than for POE and EVA, which requires adaption of the photovoltaic (PV) module lamination parameters. The test modules comprising the different encapsulation films show minor differences in the electrical performance after manufacturing; upon accelerated aging, no significant power loss is observed. But compared to TPO or POE, after 3000 h of damp heat exposure, test modules with EVA show the beginning of corrosion effects at the silver grid and above the ribbons. Based on the results, it can be stated that the new polyolefin encapsulation materials show great potential to be a valid replacement for EVA.

AbstractCommon bean rust, Bean golden yellow mosaic virus (BGYMV), Bean common mosaic virus (BCMV), and Bean common mosaic necrosis virus (BCMNV) are devastating diseases of dry bean (Phaseolus vulgaris L.) in Central America and the Caribbean. The development of dry bean cultivars with enhanced levels of genetic resistance to these and other diseases is an important goal of the University of Puerto Rico (UPR) and other dry bean breeding programs in Central America and the Caribbean. PR1572‐19 (Reg. no. GP‐308, PI 692976) and PR1572‐26 (Reg. no. GP‐307, PI 692975) are multiple virus‐ and rust‐resistant pinto bean germplasm lines adapted to the humid tropics that were developed and released cooperatively in 2019 by the UPR Agricultural Experiment Station, the Instituto Dominicano de Investigaciones Agropecuarias y Forestales, and the USDA–ARS. Both PR1572‐19 and PR1572‐26 possess the bgm‐1 gene for resistance to BGYMV, the I and bc‐3 loci that provide broad resistance to all strains of BCMV and BCMNV in the United States and the Caribbean, and the Ur‐3 and Ur‐11 loci that confer comprehensive resistance to all known races of the bean rust pathogen. PR1572‐26 also has the SW12 quantitative trait locus marker associated with resistance to BGYMV. PR1572‐19 and PR1572‐26 produced mean seed yields similar to the check cultivar ‘Santa Fe’ in trials conducted in Puerto Rico and mean seed yields comparable to the pinto cultivar ‘La Paz’ in the Cooperative Dry Bean Nursery conducted in Puerto Rico. Both lines should serve as useful sources of resistance to BGYMV, BCMV, BCMNV, and bean rust for common beans of the Durango race that includes the pinto and great northern market classes.
Analyzing Ribosome Remodeling in Health and Disease
Authors: Petelski Aleksandra A. , Slavov Nikolai 
Published: August 2020

AbstractIncreasing evidence suggests that ribosomes actively regulate protein synthesis. However, much of this evidence is indirect, leaving this layer of gene regulation largely unexplored, in part due to methodological limitations. Indeed, evidence is reviewed demonstrating that commonly used methods, such as transcriptomics, are inadequate because the variability in mRNAs coding for ribosomal proteins (RP) does not necessarily correspond to RP variability. Thus protein remodeling of ribosomes should be investigated by methods that allow direct quantification of RPs, ideally of isolated ribosomes. Such methods are reviewed, focusing on mass spectrometry and emphasizing method‐specific biases and approaches to control these biases. It is argued that using multiple complementary methods can help reduce the danger of interpreting reproducible systematic biases as evidence for ribosome remodeling.
Comparing the binding properties of peptides mimicking the Envelope protein of SARS‐CoV and SARS‐CoV‐2 to the PDZ domain of the tight junction‐associated PALS1 protein

AbstractThe Envelope protein (E) is one of the four structural proteins encoded by the genome of SARS‐CoV and SARS‐CoV‐2 Coronaviruses. It is an integral membrane protein, highly expressed in the host cell, which is known to have an important role in Coronaviruses maturation, assembly and virulence. The E protein presents a PDZ‐binding motif at its C‐terminus. One of the key interactors of the E protein in the intracellular environment is the PDZ containing protein PALS1. This interaction is known to play a key role in the SARS‐CoV pathology and suspected to affect the integrity of the lung epithelia. In this paper we measured and compared the affinity of peptides mimicking the E protein from SARS‐CoV and SARS‐CoV‐2 for the PDZ domain of PALS1, through equilibrium and kinetic binding experiments. Our results support the hypothesis that the increased virulence of SARS‐CoV‐2 compared to SARS‐CoV may rely on the increased affinity of its Envelope protein for PALS1.
Effects of rotational degree of freedom on calculations of photoassociation of HeH+ systems
Authors: Wang Bin‐Bin 
Published: August 2020

AbstractThe role of rotational degree of freedom in calculations of photoassociation (PA) and the accompanying phenomena, that is, multiphoton transitions and above‐threshold dissociations (PA‐ATDs), of HeH+ systems is investigated by comparing the numerical results of the one‐dimensional (1D) and three‐dimensional (3D) models in the framework of the time‐dependent quantum wave packet method. It was found that the PA probability of the target state predicted by the 3D model is much smaller than that predicted by the 1D model. In addition, as the bound energies of interaction potential can be shifted by the inclusion of the rotational degree of freedom, the amplitude and frequency of optimized laser pulses obtained based on the 1D model should be changed to some extent to obtain maximal PA probability of the target state in realistic systems. The multiphoton transitions in the 3D case tend to be much easier to be excited. The variational behaviors of the PA‐ATD probability vs the initial relative momentum of the two colliding particles, calculated in the 3D model using the optimized laser pulses obtained based on the 1D and 3D models, are found to be nearly coincident with each other, which implies that the continuum‐continuum transitions from the initial wave packet tend to be the major dynamics in the PA‐ATD process.
Robust adaptive model predictive control: Performance and parameter estimation
Authors: Lu Xiaonan , Cannon Mark , Koksal‐Rivet Denis 
Published: August 2020

SummaryFor systems with uncertain linear models, bounded additive disturbances and state and control constraints, a robust model predictive control (MPC) algorithm incorporating online model adaptation is proposed. Sets of model parameters are identified online and employed in a robust tube MPC strategy with a nominal cost. The algorithm is shown to be recursively feasible and input‐to‐state stable. Computational tractability is ensured by using polytopic sets of fixed complexity to bound parameter sets and predicted states. Convex conditions for persistence of excitation are derived and are related to probabilistic rates of convergence and asymptotic bounds on parameter set estimates. We discuss how to balance conflicting requirements on control signals for achieving good tracking performance and parameter set estimate accuracy. Conditions for convergence of the estimated parameter set are discussed for the case of fixed complexity parameter set estimates, inexact disturbance bounds, and noisy measurements.

Abstract
Current therapies for novel coronavirus disease (COVID-19) are generally used to manage rather than cure this highly infective disease. Therefore, there is a significant unmet medical need for a safe and effective treatment for COVID-19. Inflammation is the driving force behind coronavirus infections, and the majority of deaths caused by COVID-19 are the result of acute respiratory distress syndrome (ARDS). It is crucial to control the inflammation as early as possible. To date, numerous studies have been conducted to evaluate the safety and efficacy of tissue engineering and regenerative medicine (TERM) products, including mesenchymal stem cells (MSCs), and their derivatives (eg, exosomes) for coronavirus infections, which could be applied for the COVID-19. In this review, first, the impacts of the COVID-19 pandemic in the present and future of TERM research and products are briefly presented. Then, the recent clinical trials and the therapeutic benefits of MSCs in coronavirus-induced ARDS are critically reviewed. Last, recent advances in the field of tissue engineering relevant to coronavirus infections, including three-dimensional platforms to study the disease progression and test the effects of antiviral agents, are described. Moreover, the application of biomaterials for vaccine technology and drug delivery are highlighted. Despite promising results in the preclinical and clinical applications of MSC therapy for coronavirus infections, controversy still exists, and thus further investigation is required to understand the efficacy of these therapies.

AbstractDeveloping efficient and stable non‐noble electrocatalysts for the oxygen evolution reaction (OER) remains challenging for practical applications. While nickel–iron layered double hydroxides (NiFe‐LDH) are emerging as prominent candidates with promising OER activity, their catalytic performance is still restricted by the limited active sites, poor conductivity and durability. Herein, hierarchical nickel–iron–cobalt LDH nanosheets/carbon fibers (NiFeCo‐LDH/CF) are synthesized through solvent‐thermal treatment of ZIF‐67/CF. Extended X‐ray adsorption fine structure analyses reveal that the Co substitution can stabilize the Fe local coordination environment and facilitate the π‐symmetry bonding orbital in NiFeCo‐LDH/CF, thus modifying the electronic structures. Coupling with the structural advantages, including the largely exposed active surface sites and facilitated charge transfer pathway ensured by CF, the resultant NiFeCo‐LDH/CF exhibits excellent OER activity with an overpotential of 249 mV at 10 mA cm−1 as well as robust stability over 20 h.
Estimation of productivity and markups with price dispersion: Evidence from Chinese manufacturing during economic transition

Published: August 2020

AbstractWe estimate firm productivity and markups in the presence of heterogeneous output and input prices. We assume that firms are monopolistically competitive in the output market and that state firms are favored and pay lower prices for inputs due to political connections. The proxy‐variable (or called the control‐function‐based) approach of structurally identifying production functions and productivity is customized to our new setting. Our approach solves the underidentification problem inherent in the standard proxy‐variable method. We investigate the Chinese transportation equipment industry and find evidence against perfect competition and price homogeneity. We also find that productivity and markup differentials and dynamics are consistent with the market‐oriented reforms in China.
Influences of different stone powders on pervious concrete strength
Authors: Abdulwahid Mohanad Yaseen 
Published: August 2020

AbstractThis paper focuses on the effect of different types of stone powders as a partial replacement of coarse aggregate on the strength and porosity of pervious concrete. The used stones in this study were gathered from the foothill of Haibat–Sultan Mountain of Koya city located in Kurdistan region of Iraq. Four types of stones were used; mudstone, sandstone, marlstone, and limestone as 7% partial replacement of coarse aggregate. For all mixes, the same mix proportion of 1:4.5:0.4 by weight for cement, coarse aggregate, and water, respectively, was used. The test results have shown a noticeable decrease of porosity for all types of mixes, with an increase in the compressive and splitting tensile strength. The results displayed also the great role played by the fineness of stone filler in improving the strength of pervious concrete with acceptable porosity. Besides, they indicated that the sandstone and marlstone powders are effective filler in improving the strength of pervious concrete.
Exploring Enzymatic Activity in Multiparameter Space: Cosolvents, Macromolecular Crowders and Pressure
Authors: Jaworek Michel W. , Winter Roland 
Published: August 2020

AbstractThe use of cosolutes and high hydrostatic pressure has been described as an efficient means to modulate the stability of enzymes and their catalytic activity. Cosolvents and pressure can lead to increased reaction rates without compromising the stability of the enzyme. Inspired by the multi‐component nature of the crowded cellular milieu of biological cells of piezophiles, we studied the combined effects of macromolecular crowding agents, different types of cosolvents and pressure in concert on a hydrolysis reaction catalyzed by α‐chymotrypsin. We have seen that crowding agents and cosolvents can have very diverse effects on enzymatic activity. Addition of the deep‐sea osmolyte trimethylamine‐N‐oxide displays by far the most positive effect on the catalytic efficiency, keff, of the reaction, which is even markedly enhanced at high pressures. Addition of the chaotropic agent urea leads to the reverse effect, and PEG and dextran as two representative crowding agents of a different nature show nearly similar values for keff compared to the pure buffer data. Such information may not only be relevant for understanding life processes in extreme environments, but also for the use of enzymes in industrial processing, which often requires harsh conditions as well.
