Authors: Al‐Atrash Farah Z. , Hamdan Na'ela , Mualla Raneem 
Published: June 2023

AbstractThe presented research addresses shortcomings in refugee camps in Jordan where humanitarian needs cannot be fully met. It provides an overview of significance of sustainability in shelter design and aims to rethink the future design process by giving more consideration to site factors of the camp area. It also describes the use of simulation programmes to create a well‐designed shelter module. The study focuses on the construction of energy‐efficient shelters for displaced persons in the region, with an emphasis on improving the indoor climate and reducing energy consumption. To answer the research question, hybrid data systems were used for two purposes: first, to identify the design factors associated with refugee shelter design, and second, to categorise these factors and incorporate them into the simulation to get the ideal module design. The simulation software SIM VICUS was used. As a result, basalt is proposed to be used for the design of new refugee shelters in Jordan. The basalt fibre panel as a construction material gives very good results for achieving sufficient indoor thermal comfort for the shelters. With the proposed design, the maximum indoor temperature in the hot season can be limited to 29.2 °C, with a difference of 10.8 K. In the cold season, the indoor temperature was low. In the cold season, the lowest indoor temperatures were 11.4 °C with a difference of 12.7 K.

Published: June 2023

AbstractEine verheerende Flut im Ahrtal im Juli 2021 forderte 134 Todesopfer und verursachte massive Schäden an der Infrastruktur, auch an den Brücken. Die Flutwelle wurde durch eine Kombination von Faktoren verursacht, darunter starke Niederschläge, ein großes Einzugsgebiet, gesättigte Böden, enge Täler und Schieferhänge. Die zahlreichen Brückenbauwerke wirkten teilweise als vorübergehender Damm, der schließlich unter der Belastung des Wassers und Geschiebes versagte und weggerissen wurde, wodurch sich der ohnehin schon flutartige Abfluss der Ahr zu einer Flutwelle kumulierte. Rund 60 Brückenbauwerke wurden zerstört – allein in der Stadt Bad Neuenahr‐Ahrweiler waren es 23 von 25 Brücken. Als schnelle, hilfreiche Lösung für die betroffenen Bürger wurden zwischenzeitlich einige Behelfsbrücken errichtet, um die Planungs‐ und Bauzeit für neue dauerhafte Bauwerke zu überbrücken. In diesem Beitrag wird über diese Behelfsbrücken und deren Konstruktion berichtet.

Published: June 2023

AbstractA series of Mn4+‐doped and Mn4+,K+‐co‐doped Ba2LaTaO6 (BLT) double‐perovskite phosphors was synthesized using a high‐temperature solid‐state reaction. The phase purity and luminescence properties were also studied. The optimum doping concentration of Mn4+ and K+ was obtained by investigating the photoluminescence excitation spectra and photoluminescence emission spectra. The comparison of BLT:Mn4+ phosphors with and without K+ ions shows that the photoluminescence intensity of K+‐doped phosphors was greatly enhanced. This is because there was a charge difference when Mn4+ ions were doped with Ta5+ ions in BLT. Mn4+–K+ ion pairs were formed after doping K+ ions, which hinders the nonradiative energy transfer between Mn4+ ions. Therefore, the luminescence intensity, quantum yield, and thermal stability of phosphors were enhanced. The electroluminescence spectra of BLT:Mn4+ and BLT:Mn4+,K+ were measured. The spectra showed that the light emitted from the phosphors corresponded well with chlorophyll a and phytochrome PR. The results show that the BLT:Mn4+,K+ phosphors had good luminescence properties and application prospects and are ideal materials for plant‐illuminated red phosphors.

Published: June 2023

AbstractHigh‐throughput western blot (WB) analysis can be used to obtain more consistent, comparable, and informative data from precious samples and materials with extremely limited availability, such as various age‐related, subtype‐specific human induced neurons (hiNs). In this study, p‐toluenesulfonic acid (PTSA), an odorless tissue fixative, was used to inactivate horseradish peroxidase (HRP) and develop a high‐throughput WB method. PTSA‐treated blots demonstrated rapid and efficient HRP inactivation without detectable protein loss or epitope damage. With a brief PTSA treatment (1 min at room temperature [RT]) before every subsequent probing, 10 dopaminergic hiN proteins could be sequentially, sensitively, and specifically detected in the blot. The resulting WB data confirmed the age‐associated and neuron‐specific features of hiNs and revealed a significant reduction in two Parkinson's disease‐associated proteins, UCHL1 and GAP43, in normal aging dopaminergic neurons. Overall, this study developed a unique and high‐efficiency WB analysis method for capturing robust and useful data from limited, precious samples.

Published: June 2023

AbstractThe implementation of continuous processing in the biopharmaceutical industry is hindered by the scarcity of process analytical technologies (PAT). To monitor and control a continuous process, PAT tools will be crucial to measure real‐time product quality attributes such as protein aggregation. Miniaturizing these analytical techniques can increase measurement speed and enable faster decision‐making. A fluorescent dye (FD)‐based miniaturized sensor has previously been developed: a zigzag microchannel which mixes two streams under 30 s. Bis‐ANS and CCVJ, two established FDs, were employed in this micromixer to detect aggregation of the biopharmaceutical monoclonal antibody (mAb). Both FDs were able to robustly detect aggregation levels starting at 2.5%. However, the real‐time measurement provided by the microfluidic sensor still needs to be implemented and assessed in an integrated continuous downstream process. In this work, the micromixer is implemented in a lab‐scale integrated system for the purification of mAbs, established in an ÄKTA™ unit. A viral inactivation and two polishing steps were reproduced, sending a sample of the product pool after each phase directly to the microfluidic sensor for aggregate detection. An additional UV sensor was connected after the micromixer and an increase in its signal would indicate that aggregates were present in the sample. The at‐line miniaturized PAT tool provides a fast aggregation measurement, under 10 min, enabling better process understanding and control.
The influence of collectivism on consumer responses to green behavior
Authors: Ogiemwonyi Osarodion , Jan Muhammad Tahir 
Published: June 2023

AbstractThe purpose of this research is to examine consumer responses to green behavior linking constructs like attitude, perceived behavioral control (PBC), and subjective norms (SN) from the theory of planned behavior (TPB) model in connection to cultural dimension influence such as collectivism. A well‐established survey was developed to capture adequate responses using a quantitative approach. SmartPLSver3.3 were applied to the reliability and path relationship analysis. Results indicate that collectivism influences green behavior and multiple factors of the TPB constructs (attitude, PBC, and SN). In addition, PBC exerted a positive influence on SN, which significantly accelerated green behavior. Likewise, attitude positively mediates collectivism, PBC, and the green behavior nexus. The research shows that responses to green behavior are the solution in attaining the sustainable development goal −12 in a collectivist society as consumers with a stronger collectivist orientation rely on group identity and are disposed to engage in responsible consumption and production owing to their strong attitude, perceived control, and social norms. The study contributes meaningful insights to new lines of research on how to eliminate perceived difficulty linked to green consumption and improve responses to green behavior, which is still a concern; thus, policymakers must try to improve collectivist values.
Organizational heuristics and firms' sensemaking for climate change adaptation
Authors: Bleda Mercedes , Krull Elisabeth , Pinkse Jonatan , Christodoulou Eleni 
Published: June 2023

AbstractThe complexity and uncertainty of climate change pose unique challenges to the development of corporate adaptation strategies. Climate adaptation requires organizations to rely on sensemaking to understand climate events, implications for their operations, and develop a response. Organizational heuristics can support sensemaking by simplifying decisions and reducing cognitive effort but also hinder it by creating bias and errors that lead to inefficient decisions. This paper analyzes how firms use organizational heuristics when making decisions on climate change by empirically investigating the adaptation responses of key infrastructure providers in the United Kingdom. Looking at selection, prioritization, procedural, and temporal heuristics, we examine how firms make sense of climate events and develop their responses accordingly. The analysis shows that while these rules‐of‐thumb are sensible in some instances, they can create biases, too, that may deflect responsibility or create a false sense of security leading to inefficient adaptation decisions.
Patterns of buyer behavior and brand metrics in a “high loyalty” category: Liquor
Authors: Dawes John G. 
Published: June 2023

AbstractThis study examines behavioral brand loyalty in a category that, based on industry evidence, is expected to exhibit high loyalty: liquor (distilled spirits). The study aims to extend knowledge of the factors that underlie behavioral loyalty, including brand characteristics of price level and promotion incidence, and buyer characteristics of age and income. Drawing on theory and evidence relating to prospect theory, the “smart shopper” concept, as well as literature pertaining to age and loyalty, we develop a series of hypotheses and test them using extensive consumer panel purchasing data for US households. The analysis confirms that liquor is indeed a high loyalty category in the context of consumer goods, evidenced via high share of category requirements (SCR). The study also identifies that liquor brands follow the double jeopardy pattern, whereby larger‐share brands enjoy somewhat higher loyalty, and that exceptions—brands with unusually high or low volume loyalty for their size—are related to high volume purchased per occasion. In turn, there is a strong negative association between brand price and high average volume purchased per occasion (i.e., cheaper brands are bought in larger quantity or volume than expensive ones). The study also finds that brands with a low price tend to be particularly attractive to low‐income households, and that, in turn, low‐income households exhibit higher brand loyalty. These new findings contribute to the literature on brand loyalty and the links between loyalty, brand characteristics, and demographics.

Published: June 2023

AbstractSamarium diiodide (SmI2) is widely used as a strong one‐electron reducing agent and is often employed to form C−C bonds in complex systems. Despite their utility, SmI2 and related salts suffer from several drawbacks that render the use of Sm reducing agents in large‐scale synthesis impractical. Here, we report factors influencing the electrochemical reduction of Sm(III) to Sm(II), towards the goal of electrocatalytic Sm(III) reduction. We probe the effect of supporting electrolyte, electrode material, and Sm precursor on Sm(II)/(III) redox and on the reducing power of the Sm species. We find that the coordination strength of the counteranion of the Sm salt affects the reversibility and redox potential of the Sm(II)/(III) couple and establish that the counteranion primarily determines the reducibility of Sm(III). Electrochemically generated SmI2 performs similarly to commercial SmI2 solutions in a proof‐of‐concept reaction. The results will provide fundamental insight to facilitate the development of Sm‐electrocatalytic reactions.

AbstractBackgroundConflicting evidence exists regarding the association between marital status and outcomes in patients with heart failure (HF). Further, it is not clear whether type of unmarried status (never married, divorced, or widowed) disparities exist in this context.HypothesisWe hypothesized that marital status will be associated with better outcomes in patients with HF.MethodsThis single‐center retrospective study utilized a cohort of 7457 patients admitted with acute decompensated HF (ADHF) between 2007 and 2017. We compared baseline characteristics, clinical indices, and outcomes of these patients grouped by their marital status. Cox regression analysis was used to explore the independency of the association between marital status and long‐term outcomes.ResultsMarried patients accounted for 52% of the population while 37%, 9%, and 2% were widowed, divorced, and never married, respectively. Unmarried patients were older (79.8 ± 11.5 vs. 74.8 ± 11.1 years; p < 0.001), more frequently women (71.4% vs. 33.2%; p < 0.001), and less likely to have traditional cardiovascular comorbidities. Compared with married patients, all‐cause mortality incidence was higher in unmarried patients at 30 days (14.7% vs. 11.1%, p < 0.001), 1 year, and 5 years (72.9% vs. 68.4%, p < 0.001). Nonadjusted Kaplan‐Meier estimates for 5‐year all‐cause mortality by sex, demonstrated the best prognosis for married women, and by marital status in unmarried patients, the best prognosis was demonstrated in divorced patients while the worst was recorded in widowed patients. After adjustment for covariates, marital status was not found to be independently associated with ADHF outcomes.ConclusionsMarital status is not independently associated with outcomes of patients admitted for ADHF. Efforts for outcomes improvement should focus on other, more traditional risk factors.

Published: June 2023

AbstractRoot canal irrigation is an important step in root canal preparation procedures and has a great impact on the success rate of root canal treatment. Computational fluid dynamics (CFD) is a new method to study root canal irrigation. It can be used to simulate and visualize the process of root canal irrigation, and quantitatively evaluate the effect of root canal irrigation through parameters such as flow velocity and wall shear stress. In recent years, researchers have conducted extensive studies on the factors that influence root canal irrigation efficiency, such as the position of the irrigation needle, the size of root canal preparation, the types of irrigation needles, and so on. This article reviewed the development of root canal irrigation research methods, the steps of CFD simulation in root canal irrigation, and the application of CFD in root canal irrigation in recent years. It aimed to provide new research ideas for the application of CFD to root canal irrigation and to provide a reference for the clinical application of CFD simulation results.
FUCBR: Fuzzy‐based unequal clustering and bat‐based routing protocol for WSNs assisted IoT
Authors: Agrawal Deepika , Pandey Sudhakar 
Published: June 2023

SummaryThe internet of things (IoT) has recently become extremely important in our lives. With the advancement in IoT, wireless sensor networks (WSNs) have gained much importance. In WSNs, the routing of clusters has gained more interest. However, there is still a problem with the hotspot. One way to address this issue is uneven clustering. In these, nodes closer to the base station have the smallest cluster size. It decreases the relay pressure of the nodes which are close to the base station. In this paper, the unequal clustering routing based on fuzzy logic and bat algorithm is proposed, that is, FUCBR. Relative intra‐cluster costs and relative inter‐cluster costs are used in a very innovative manner. Fuzzy logic is used to create unequal clusters while the bat algorithm is used for multi‐hop routing. Unequal clustering minimizes the energy utilization for the member of the clusters. A novel probability technique is implemented in the cluster‐forming process to allow cluster members to determine which cluster they wish to join. The bat algorithm's objective function is carefully chosen to optimize the cluster heads' energy usage. After simulation, it was discovered that the proposed algorithm utilizes less energy and extends the network lifespan. The simulation results show that FUCBR's performance is 30% more improved than fuzzy‐based unequal clustering algorithm, genetic algorithm based unequal clustering and routing protocol, and grey wolf optimizer‐C algorithms. It is suitable for networks that require a long life.
Solid‐State NMR Double‐Quantum Dipolar Recoupling Enhanced by Additional Phase Modulation
Authors: Xiao Hang , Zhang Zhengfeng , Kang Huimin , Yang Jun 
Published: June 2023

AbstractAdditional phase modulation (APM) is proposed to generally enhance the theoretical efficiency of homonuclear double‐quantum (DQ) recoupling in solid‐state NMR. APM applies an additional phase list to DQ recoupling in steps of an entire block. The sine‐based phase list can enhance the theoretical efficiency by 15–30 %, from 0.52 to 0.68 (non‐γ‐encoded recoupling) or from 0.73 to 0.84 (γ‐encoded recoupling), with doubled recoupling time. The genetic‐algorithm (GA) optimized APM can adiabatically enhance the efficiency to ∼1.0 at longer times. The concept of APM has been tested on SPR‐51, BaBa, and SPR‐31, which represent γ‐encoded recoupling, non‐γ‐encoded recoupling, and another kind beyond the former two, respectively. Simulations reveal that enhancements from APM are due to the activation of more crystallites in the powder. Experiments on 2,3‐13C labeled alanine are used to validate the APM recoupling. This new concept shall shed light on developing more efficient homonuclear recoupling methods.

Published: June 2023

AbstractNitrogen‐doped carbon is considered one of the most promising oxygen reduction catalysts due to its low cost and high activity, however, it still falls short of Pt/C. In this study, we report a strategy for the preparation of highly reactive N‐doped hierarchical porous carbon by primary pyrolysis using zinc acetate as a stand‐alone zinc source and amino‐rich reactants as carbon and nitrogen sources to introduce Zn‐Nx structures into mesoporous structures generated by the hard template method using the strong coordination of zinc and amino groups. Benefited from the simultaneous optimization of the hierarchical porous structure and nitrogen‐doping, the half‐wave potential of Zn(OAc)2–DCD/HPC is as high as 0.909 V vs. RHE, much better than that of commercial Pt/C catalysts (0.872 V vs. RHE). In addition, zinc‐air batteries assembled with Zn(OAc)2–DCD/HPC (Pmax=198 mW cm−2) as the cathode exhibit higher peak power density compared to Pt/C (Pmax=168 mW cm−2). This strategy might open up new opportunities for designing and developing highly active metal‐free catalysts.
Overview Update: Computational Prediction of Intrinsic Disorder in Proteins
Authors: Uversky Vladimir N. , Kurgan Lukasz 
Published: June 2023

AbstractThere are over 100 computational predictors of intrinsic disorder. These methods predict amino acid‐level propensities for disorder directly from protein sequences. The propensities can be used to annotate putative disordered residues and regions. This unit provides a practical and holistic introduction to the sequence‐based intrinsic disorder prediction. We define intrinsic disorder, explain the format of computational prediction of disorder, and identify and describe several accurate predictors. We also introduce recently released databases of intrinsic disorder predictions and use an illustrative example to provide insights into how predictions should be interpreted and combined. Lastly, we summarize key experimental methods that can be used to validate computational predictions. © 2023 Wiley Periodicals LLC.
Sustainability in times of crisis: Female employment during COVID‐19
Authors: Uribe Bohorquez Maria Victoria , García Sánchez Isabel María 
Published: June 2023

AbstractIn periods of crisis, companies face a financial reality that forces them to decide whether to maintain their commitment to sustainability or prioritize their financial returns. The study of what happened during the COVID‐19 pandemic is vital, given the hard blow it has implied for business and, consequently, for employment. Thus, this paper seeks to determine whether the business commitment to sustainability policies focused on employment and gender diversity translates into concrete results. In a sample of 1761 multinationals (8963 observations) during the 2015–2020 period, we found that the pandemic has harmed employment at the microeconomic level. However, this impact is moderated by the level of responsibility that companies have with their workers. Therefore, the most sustainable companies have been more reluctant to reduce their workforce and even more so when they are women. These results help to position sustainability performance as a way to achieve gender equality at the business level.
