Authors: Liu Menglei , Qiu Wei , Xiao Rengui , Li Bo , Liao Xia 
Published: February 2022

AbstractThe synergistic effect of chloride ions and industrial corrosive gases in the atmosphere intensifies metal corrosion. Therefore, the study of this corrosive behavior and its effects on metals in complex environments is crucial. In this study, the wet/dry cyclic corrosion test, under a constant deposited salt, was used to simulate atmospheric corrosion conditions. In addition, the methods of corrosion weight gain, dynamic potential polarization curves, electrochemical impedance spectroscopy, and other analyses were used to explore the mechanism and law of Q235 steel with different corrosion times in different coastal‐industrial atmospheric environments. The corrosion pattern of Q235 steel and the composition of the rust layer were further investigated through X‐Ray Diffractometer analysis and Scanning Electron Microscope observations. The results show that the content of Fe3O4 decreases at higher chloride ion concentrations and the content of α‐FeOOH increases in later stages of corrosion.

AbstractThe porous carbon material is widely used as acetone adsorbent. The low‐cost, facile and efficient synthesis method of porous carbon material is of great significance to the removal of acetone. Potassium citrate, a common organic salt, was self‐activated in the current study at the temperatures of 600–900 °C to form porous carbons (KAC−X) with rich microporous structures. The KAC−X showed excellent specific surface area (763–2100 m2 g−1) and oxygen content (5.95–16.29 wt%). The sample obtained at the temperature of 900 °C showed promising acetone adsorption capacities of 8.33 mmol g−1 (15 °C) and 7.27 mmol g−1 (25 °C), respectively. The acetone adsorption results were well fitted by the Langmuir‐Freundlich and Freundlich models. Moreover, the influence of physical structure and oxygen functional group on the acetone adsorption performance was explored. The results showed that: (1) one of the main methods for promoting the acetone adsorption capacity is to increase the specific surface area; (2) the other method is to increase the optimal pore volume, and the optimal pore size is 2–5 times of the acetone molecule diameter; (3) carboxyl and carbonyl groups can significantly increase the adsorption affinity between acetone molecule and KAC−X, and play an auxiliary role on the acetone adsorption. This study provides guidance for the facile synthesis of porous carbons from organic salt for the sake of acetone adsorption.

AbstractThe selective fragmentation of internal alkynyl esters RC≡CCO2Me into RC≡C, C=O, and OMe fragments was investigated using a gallane(pyridyl)iron complex Cp*(OC)Fe{(η1‐HGaMes2)(η1‐2‐C5H4N)} (1, Cp*: η5‐C5Me5, Mes: 2,4,6‐Me3C6H2). The reaction of complex 1 with RC≡CCO2Me (R=Ph, CO2Me) in C7D8 (toluene) at 100 °C for 0.5 h proceeded via selective C−O and C−C bond cleavage to afford η1‐alkynyliron complex Cp*(OC)2Fe(C≡CR) (R=Ph (5 a), CO2Me (5 b)) and 4‐membered Ga2O2 cyclic gallane [Mes2GaOMe]2 (3). In contrast, the reaction of 1 with methyl propiolate HC≡CCO2Me yielded a complex mixture, including gallane 3, Cp*(OC)2Fe(C≡CH) (5 c), and Cp*(OC)Fe(C≡CCO2Me)(GaMes2)(H) (F). The oxidative addition of the terminal H−C bond to the iron center occurred via the reaction of complex 1 with trimethylsilylacetylene (TMSA) and the photochemical reaction of dimesitylgallyliron complex Cp*(OC)2FeGaMes2 (4) with TMSA to afford η1‐alkynyl(gallyl)(hydride)iron complex Cp*(OC)Fe(C≡CSiMe3)(GaMes2)(H) (6).

Published: February 2022

AbstractThe Mg−Al composite supports (MgAlO) with different Mg/Al ratios were prepared by hydrothermal method. Then a series of PtSn/MgAlO catalysts were prepared and the influence of Mg/Al ratios on the physicochemical properties and the catalytic performances for propane dehydrogenation were investigated. The catalysts were characterized by means of X‐ray diffraction, N2 adsorption‐desorption, H2 temperature‐programmed reduction, NH3 temperature‐programmed desorption and Raman. Compared with Al2O3 and MgO support, MgAlO support is beneficial to the dispersion of Pt. And the dispersion of Pt is influenced by the Mg/Al ratios. When the ratio of Mg/Al is 1/10, the dispersion of Pt is the highest, which results in high propane dehydrogenation activity.
Efficient Synthesis of 7H‐Chromeno[3,2‐c]quinolin‐5‐ium Salts and Quinolin‐4‐ones through Acid‐Promoted Cascade Reaction of 3‐Formylchromones and Anilines

Published: February 2022

AbstractWe report an efficient and environment‐friendly approach for the synthesis of multisubstituted 7‐oxo‐7H‐chromeno[3,2‐c]quinolin‐5‐ium salts using ambient air as a green sole oxidant. The chromeno[3,2‐c]quinolin‐5‐ium salts were prepared through metal‐free cascade intermolecular cycloaddition/oxidation reaction of 3‐formylchromones and N‐substituted anilines using HClO4 as the reagent and promoter under concise one‐pot conditions. In the applied research, the resulting quinolinium salts could serve as synthons and could be further transformed to diverse synthetically useful 3‐(2‐hydroxy‐benzoyl)quinolin‐4‐ones in water. This protocol offers a simple cascade strategy to synthesize a wide variety of natural‐like chromeno[3,2‐c]quinolin‐5‐ium salts and quinolin‐4‐ones, and shows some academic research potential as well as industrial applications.

Published: February 2022

AbstractCaZnOS‐based semiconductors are the only series of material system discovered that can simultaneously realize a large number of dopant elements to directly fulfill the highly efficient full‐spectrum functionality from ultraviolet to near‐infrared under the same force/pressure. Nevertheless, owing to the high agglomeration of the high temperature solid phase manufacturing process, which is unable to control the crystal morphology, the application progress is limited. Here, the authors report first that CaZnOS‐based fine monodisperse semiconductor crystals with various doping ions are successfully synthesized by a molten salt shielded method in an air environment. This method does not require inert gas ventilation, and therefore can greatly reduce the synthesis cost and more importantly improve the fine control of the crystal morphology, along with the crystals’ dispersibility and stability. These doped semiconductors can not only realize different colors of mechanical‐to‐optical energy conversion, but also can achieve multicolor luminescence under low‐dose X‐ray irradiation, moreover their intensities are comparable to the commercial NaI:Tl. They can pave the way to the new fields of advanced optoelectronic applications, such as piezophotonic systems, mechanical energy conversion and harvesting devices, intelligent sensors, and artificial skin as well as X‐ray applications.
Software Process Evaluation from User Perceptions and Log Data

Published: February 2022

AbstractCompanies often claim to follow specific software development methodologies (SDM) when performing their software development process. These methodologies are often supported by dedicated tools that keep track of work activities carried out by developers. The purpose of this paper is to provide a novel approach that integrates analytical insights from both the perceptions of SDM stakeholders and software development tools logs to provide SDM improvement recommendations. This paper develops a new process improvement approach that combines two significantly different sources of data on the same phenomenon. First, it uses a questionnaire to gather software development stakeholder SDM perceptions (managers and developers). Second, it leverages process mining to analyze software development tools logs to obtain additional information on software development activities. Finally, it develops recommendations based on concurrent analysis of both sources. Our novel process improvement approach is evaluated in three directions: Does the presented approach (RQ1) enable managers to gain additional insights into employees' performance, (RQ2) deliver additional insights into project performance, and (RQ3) enable development of additional SDM improvement recommendations? We find that integrated analysis of software development perception data and software development tools logs opens new possibilities to more precisely identify and improve specific SDM elements. The evaluation of our novel process improvement approach follows a single case study design. Our approach can only be used in enterprises in which software development tools logs are available. The study should be repeated in different cultural settings. We practically show how concurrently analyzing data about developer SDM perceptions and event log data from software development tools enables management to gain additional insights in the software development process regarding the performance of individual developers. The main theoretical contribution of our paper is a novel process improvement approach that effectively integrates data from management and developer perspectives and software development tools logs.
Combined microwave‐assisted extraction and headspace gas chromatography for hexanal determination in fat‐rich food

Published: February 2022

AbstractThe feasibility of a new approach for the determination of volatiles in solid matrices by coupling microwave‐assisted extraction with static headspace gas chromatography has been demonstrated using hexanal as an analyte present in fat‐rich food. Eight polar and low volatility deep eutectic solvents were prepared using microwave heating and examined for hexanal extraction. Choline chloride‐glucose‐water showed the best transition efficiency of hexanal to the headspace and was applied to extract hexanal using microwave‐assisted extraction. Hexanal released from the fat‐rich food is poorly soluble in the hydrophilic deep eutectic solvent choline chloride‐glucose‐water so enters the gas phase and subsequently dissolves in coconut oil fixed above the extraction mixture in a polypropylene capillary. After cooling the capillary was transferred to a headspace vial and headspace gas chromatography was carried out. Under optimized conditions, the limit of detection was 3.1 μg g–1. The developed approach was successfully applied to analyze hexanal in fat‐rich food.
A novel damped braced tube system for tall buildings in high seismic zones

Published: February 2022

SummaryThe damped outrigger system is known to efficiently provide additional damping in buildings with heights of over 250 m. However, particularly for supertall buildings in the center of Tokyo, Japan, the outrigger truss from the center core to the exterior columns need to span distances of more than 20 m. This increases the flexural stiffness demand on the outrigger that leads to larger truss depths making the damped outrigger system inefficient. For such tall buildings with large plans, a new damping modification system, the “damped braced tube system” is proposed, where the exterior surface of the elastic mega braces are partially removed vertically to create a split and are replaced with dissipaters (energy‐dissipation devices). The damped braced tube system enhances the seismic performance as the exterior surfaces of the elastic mega braces work together with the damped slits like in a coupled wall system and increases the overall damping ratio. In this paper, numerical models were constructed based on a real project in Japan consisting of a 397‐m supertall building employing the damped tubular braced system using oil dampers (referred to as viscous dissipaters). A series of generalized response spectrum based numerical analyses and optimizations were performed to minimize the seismic response. The proposed system exhibited improved damping performance with the first to third mode damping ratios reaching to more than 7% while providing a wide range of options for dissipater distribution for design. Finally, the elevation of the slit's base is recommended to be equal to 0.22 of the total building height considering the trade‐off relationship between the first modal damping ratio and the fundamental period.

Quantum symmetries in orbifolds and decomposition
Authors: Robbins Daniel G. , Sharpe Eric , Vandermeulen Thomas 
Published: February 2022

Abstract
In this paper, we introduce a new set of modular-invariant phase factors for orbifolds with trivially-acting subgroups, analogous to discrete torsion and generalizing quantum symmetries. After describing their basic properties, we generalize decomposition to include orbifolds with these new phase factors, making a precise proposal for how such orbifolds are equivalent to disjoint unions of other orbifolds without trivially-acting subgroups or one-form symmetries, which we check in numerous examples.
Electroweak-Skyrmion as asymmetric dark matter
Authors: Hamada Yu , Kitano Ryuichiro , Kurachi Masafumi 
Published: February 2022

Abstract
We propose a scenario that the Electroweak-Skyrmion, a solitonic object made of the Higgs field and the electroweak gauge fields, is identified as an asymmetric dark matter. In this scenario, the relic abundance of the dark matter is related to the baryon asymmetry of the Universe through a sphaleron-like process. We show that the observed ratio of dark matter abundance to the baryon asymmetry can be explained by this scenario with an appropriate choice of model parameters that is allowed by currently available experimental constraints.
The exact WKB and the Landau-Zener transition for asymmetry in cosmological particle production
Authors: Enomoto Seishi , Matsuda Tomohiro 
Published: February 2022

Abstract
Cosmological particle production by a time-dependent scalar field is common in cosmology. We focus on the mechanism of asymmetry production when interaction explicitly violates symmetry and its motion is rapid enough to create particles by itself. Combining the exact WKB analysis and the Landau-Zener transition, we point out that perturbation before the non-perturbative analysis may drastically change the structure of the Stokes lines of the theory. The Exact WKB can play an important role in avoiding such discrepancies.
Unstable cosmic neutrino capture

Published: February 2022

Abstract
Future direct observations of the Cosmic Neutrino Background (CνB) have the potential to explore a neutrino lifetime, especially in the region of the age of the universe, t0 = 4.35 × 1017 s. We forecast constraints on neutrino decay via capture of the CνB on tritium, with emphasis on the PTOLEMY-type experiment. In addition, in some cases of invisible neutrino decay into lighter neutrinos in the Standard Model and invisible particles, we can constrain not only the neutrino lifetime but also the masses of the invisible particles. For this purpose, we also formulate the energy spectra of the lighter neutrinos produced by 2-body and 3-body decays, and those of the electrons emitted in the process of the detection of the lighter neutrinos.
Characterizations of weak reverse Hölder inequalities on metric measure spaces
Authors: Kinnunen Juha , Kurki Emma-Karoliina , Mudarra Carlos 
Published: February 2022

AbstractWe present ten different characterizations of functions satisfying a weak reverse Hölder inequality on an open subset of a metric measure space with a doubling measure. Among others, we describe these functions as a class of weak$$A_\infty $$A∞weights, which is a generalization of Muckenhoupt weights that allows for nondoubling weights. Although our main results are modeled after conditions that hold true for Muckenhoupt weights, we also discuss two conditions for Muckenhoupt$$A_\infty $$A∞weights that fail to hold for weak$$A_\infty $$A∞weights.
Does coupling to ADP ribosylation factor 6 explain differences between muscarinic and other receptors in interaction with β-adrenoceptor-mediated smooth muscle relaxation?
Authors: Erdogan Betül R. , Michel Martin C. 
Published: February 2022

AbstractNumerous studies in airways, ileum, and urinary bladder have demonstrated that relaxation by β-adrenoceptor agonists has lower potency and/or efficacy when contraction was elicited by muscarinic receptor agonists as compared to other G-protein-coupled receptors, KCl, or basal tone, but the molecular mechanisms behind this relative resistance remain unclear. A paper by Huang et al. in this issue demonstrates that NAV2729, an inhibitor of ADP ribosylation factor 6, inhibits contraction of isolated blood vessels elicited by muscarinic receptor agonists, but not by α1-adrenoceptor agonists or KCl. Against this background, we discuss the role of ADP ribosylation factor 6 in cellular responses to G-protein-coupled receptor stimulation. While ADP ribosylation factor 6 apparently is the only promising molecular explanation for the relative resistance of smooth muscle contraction elicited by muscarinic agonists, the existing data are insufficient for a robust conclusion.
Fibrin-based factor delivery for therapeutic angiogenesis: friend or foe?
Authors: Melly Ludovic , Banfi Andrea 
Published: February 2022

AbstractTherapeutic angiogenesis aims at promoting the growth of blood vessels to restore perfusion in ischemic tissues or aid tissue regeneration. Vascular endothelial growth factor (VEGF) is the master regulator of angiogenesis in development, repair, and disease. However, exploiting VEGF for therapeutic purposes has been challenging and needs to take into account some key aspects of VEGF biology. In particular, the spatial localization of angiogenic signals within the extracellular matrix is crucial for physiological assembly and function of new blood vessels. Fibrin is the provisional matrix that is universally deposited immediately after injury and supports the initial steps of tissue regeneration. It provides therefore several ideal features as a substrate to promote therapeutic vascularization, especially through its ability to present growth factors in their physiological matrix-bound state and to modulate their availability for signaling. Here, we provide an overview of fibrin uses as a tissue-engineering scaffold material and as a tunable platform to finely control dose and duration of delivery of recombinant factors in therapeutic angiogenesis. However, in some cases, fibrin has also been associated with undesirable outcomes, namely the promotion of fibrosis and scar formation that actually prevent physiological tissue regeneration. Understanding the mechanisms that tip the balance between the pro- and anti-regenerative functions of fibrin will be the key to fully exploit its therapeutic potential.
Prehatching temperatures drive inter-annual cohort differences in great tit metabolism

Published: February 2022

AbstractBasal metabolic rate (BMR) constitutes the lowest metabolic rate in a resting animal and is, therefore, considered to reflect the energetic cost of maintenance in endotherms. BMR is a reversible plastic trait that changes with environmental and ecological circumstances, albeit being heritable and susceptible to selection. Inter-individual variation within populations of small birds is substantial, and while many of the drivers of such variation have been identified, many remain unexplained. We studied winter BMR variation of juveniles over a 15-year period in a wild population of great tits Parus major at the northern border of their distribution. BMR during winter consistently changed between years, even after controlling for environmental factors, suggestive of a non-reversible developmental plasticity shaping the adult metabolic phenotype. BMR in cohorts of wintering great tits varied among winters as a response to minimum ambient temperatures experienced early in life, during the prehatching period. This developmental plasticity might be adaptive if temperatures experienced by growing embryos would metabolically prime them to an environment that they will likely encounter in future life. However, in line with a more unpredictable future climate, the risk of phenotype-environment mismatch is likely to lead to certain cohorts being poorly adapted to prevailing winter conditions, resulting in wider annual fluctuations in population size.
