Published: July 2023

Abstract
The wheel-rail impact noise caused by welding joints and rail corrugation will cause great disturbance to passengers, which is unbearable in severe cases, and is also an urgent problem to be solved at present. Resilient wheels, which feature complex structures, have demonstrated efficacy in reducing noise and vibration levels. However, the complex structure, nonlinear material behavior, and nonlinearity in the wheel-rail contact pose challenges in assessing their performance in reducing noise and vibration. To solve this problem, based on the three-dimensional wheel-rail rolling contact model, the nonlinear vibration and impact noise characteristics of resilient wheels when passing through welded joints and corrugated rails are analyzed. Research indicate that the use of resilient wheels can significantly reduce the amplitude of wheel-rail impact forces and associated noise when traversing short-wave welded joints. And it is worth noting that resilient wheels demonstrate a certain level of nonlinearity in their performance. Furthermore, we observed that the noise reduction effect of the resilient wheel is not linearly proportional to the depth of the welding joint, but is instead linked to the frequency of the corresponding corrugation wavelength. Especially, When the characteristic frequency of the corrugation is 390 Hz, the noise reduction effect of the resilient wheel can reach 6.6 dBA.
Indeterminism belief protects against uncertainty: First empirical findings
Authors: Grüning David J. , Krueger Joachim I. 
Published: July 2023

Abstract
We empirically explore whether perceptions of (in)determinism are related to the willingness to tolerate uncertainty. We argue that the belief in indeterminism supports a sense of personal autonomy and independence from external influence, a stance that provides protection from perceived uncertainties. Our preliminary study (N = 61) provides first evidence that the belief in an indeterminate world is positively associated with uncertainty tolerance, whereas beliefs in free will and metaphysical dualism are not. We extend these findings by examining proxies of indeterminism belief in a cross-national dataset (N = 31 countries). We find that greater political and personal freedom is associated with higher tolerance for uncertainty, whereas religious belief, which posits a world determined by divine powers, is negatively associated with uncertainty tolerance. With these theoretical ideas and empirical findings, we hope to stimulate research to further advance our understanding of the association between belief in indeterminism and tolerating uncertainty.

Published: July 2023

Durante a história evolutiva da Terra, alguns organismos desenvolveram a habilidade de cultivar seu próprio alimento. Formigas da tribo Attini apresentam como hábito o cultivo de fungos, que são utilizados em sua nutrição. Esse cultivo ocorre no interior dos ninhos das formigas, nos chamados jardins de fungo. Nessa complexa relação mutualística, as formigas são responsáveis por suprir os fungos simbiontes com material específico (fezes, carcaças de insetos e material vegetal em decomposição ou fresco), protegê-los contra parasitas e predadores e realizar sua dispersão. Em troca, os fungos degradam moléculas complexas, são utilizados como principal alimento das larvas e fazem parte da dieta das formigas adultas. Além do fungo cultivado, outros micro-organismos, como bactérias, leveduras e fungos filamentosos são frequentemente encontrados associados aos jardins de fungo. Entretanto, pouco se sabe sobre a diversidade e a função de micro-organismos presentes nos ninhos de formigas Attini. Assim, esta revisão bibliográfica tem como objetivo apresentar as características da relação entre as formigas e o fungo cultivado, bem como a interferência de outros micro-organismos nesses micro-habitat.

A Paralisia Cerebral (PC) é caracterizada como um grupo não progressivo, mas frequentemente mutável, de distúrbios motores, especialmente do tônus e da postura, que ocorrem após a lesão do Sistema Nervoso Central (SNC) em desenvolvimento. O objetivo do presente estudo foi avaliar o desempenho funcional de crianças com paralisia cerebral do tipo quadriplégica hipertônica. Para isso, foi aplicado, por meio de entrevista, o teste Pediatric Evaluation of Disability Inventory (PEDI), ao qual foram submetidos os pais ou responsáveis por seis crianças, com idade entre 1 ano e meio e 6 anos e 10 meses, sendo duas do sexo feminino e quatro do masculino. Os resultados demonstraram que o desempenho das crianças quadriplégicas hipertônicas foi inferior em todas as áreas avaliadas pelo PEDI, em que o padrão de normalidade varia entre 30 a 70 pontos. Também revelaram que a média de escore normativo foi de 15,63 na área de autocuidado e de 15,28 na de função social. Já na área de mobilidade, o escore normativo foi menor que 10. Concluiu-se, portanto, que o desempenho funcional de crianças com paralisia cerebral do tipo quadriplégica hipertônica é inferior ao padrão de normalidade esperado, sendo a área de mobilidade a mais prejudicada.

AbstractTwo‐dimensional dopant layers (δ‐layers) in semiconductors provide the high‐mobility electron liquids (2DELs) needed for nanoscale quantum‐electronic devices. Key parameters such as carrier densities, effective masses, and confinement thicknesses for 2DELs have traditionally been extracted from quantum magnetotransport. In principle, the parameters are immediately readable from the one‐electron spectral function that can be measured by angle‐resolved photoemission spectroscopy (ARPES). Here, buried 2DEL δ‐layers in silicon are measured with soft X‐ray (SX) ARPES to obtain detailed information about their filled conduction bands and extract device‐relevant properties. This study takes advantage of the larger probing depth and photon energy range of SX‐ARPES relative to vacuum ultraviolet (VUV) ARPES to accurately measure the δ‐layer electronic confinement. The measurements are made on ambient‐exposed samples and yield extremely thin (< 1 nm) and dense (≈1014 cm−2) 2DELs. Critically, this method is used to show that δ‐layers of arsenic exhibit better electronic confinement than δ‐layers of phosphorus fabricated under identical conditions.

AbstractProtein‐based biomaterials have played a key role in tissue engineering, and additional exciting applications as self‐healing materials and sustainable polymers are emerging. Over the past few decades, recombinant expression and production of various fibrous proteins from microbes have been demonstrated; however, the resulting proteins typically must then be purified and processed by humans to form usable fibers and materials. Here, we show that the Gram‐positive bacterium Bacillus subtilis can be programmed to secrete silk through its translocon via an orthogonal signal peptide/peptidase pair. Surprisingly, we discover that this translocation mechanism drives the silk proteins to assemble into fibers spontaneously on the cell surface, in a process we call secretion‐catalyzed assembly (SCA). Secreted silk fibers form self‐healing hydrogels with minimal processing. Alternatively, the fibers retained on the membrane provide a facile route to create engineered living materials from Bacillus cells. This work provides a blueprint to achieve autonomous assembly of protein biomaterials in useful morphologies directly from microbial factories.

AbstractRemote C−H functionalization of heterocyclic biaryls will be of great importance in synthesis and medicinal chemistry. Through adjusting the geometric relationship of the directing atom and target C−H bonds, two new catalytic templates have been developed to enable the functionalization of the more hindered ortho‐C−H bonds of heterobiaryls bearing directing heteroatom at the meta‐ or para‐positions, affording unprecedented site‐selectivity. The use of template chaperone also overcomes product inhibition and renders the directing templates catalytic. The utility of this protocol was demonstrated by olefination of heterocyclic biaryls with various substituents, overriding conventional steric and electronic effects. These ortho‐C−H olefinated heterobiaryls are sterically hindered and can often be challenging to prepare through aryl‐aryl coupling reactions.

AbstractRealizing industrial‐scale production of HCOOH from the CO2 reduction reaction (CO2RR) is very important, but the current density as well as the electrochemical potential window are still limited to date. Herein, we achieved this by integration of chemical adsorption and electrocatalytic capabilities for the CO2RR via anchoring In nanoparticles (NPs) on biomass‐derived substrates to create In/X−C (X=N, P, B) bifunctional active centers. The In NPs/chitosan‐derived N‐doped defective graphene (In/N‐dG) catalyst had outstanding performance for the CO2RR with a nearly 100 % Faradaic efficiency (FE) of HCOOH across a wide potential window. Particularly, at 1.2 A ⋅ cm−2 high current density, the FE of HCOOH was as high as 96.0 %, and the reduction potential was as low as −1.17 V vs RHE. When using a membrane electrode assembly (MEA), a pure HCOOH solution could be obtained at the cathode without further separation and purification. The FE of HCOOH was still up to 93.3 % at 0.52 A ⋅ cm−2, and the HCOOH production rate could reach 9.051 mmol ⋅ h−1 ⋅ cm−2. Our results suggested that the defects and multilayer structure in In/N‐dG could not only enhance CO2 chemical adsorption capability, but also trigger the formation of an electron‐rich catalytic environment around In sites to promote the generation of HCOOH.

AbstractChiral induction by natural biomolecules can reveal the indispensable role of chiral structures in life and can be used to develop the chirality‐sensing biomolecular recognition. Here, we present the synthesis and characterization of an achiral supramolecular organic framework (SOF‐1) constructed from cucurbit[8]uril (CB[8]) and hexaphenylbenzene (HPB) derivative (1) in water. Due to the propeller‐like rotational chiral conformation of HPB units and the specific recognition properties of CB[8], SOF‐1 demonstrates chiral adaptive induction in water when interacting with the N‐terminal Trp‐/Phe‐containing dipeptides including L‐TrpX and L‐PheX (X is an amino acid residue), respectively, exhibiting contrasting circular dichroism (CD) and circularly polarized luminescence (CPL) spectra. Consequently, SOF‐1 has been developed as a supramolecular host and chiroptical sensor capable of recognizing and distinguishing the sequence‐opposite Trp‐/Phe‐containing dipeptide pairs including L‐TrpX/L‐XTrp and L‐PheX/L‐XPhe based on the sequence‐selective CD responses.

AbstractThe sluggish kinetics process and shuttling of soluble intermediates present in complex conversion between sulfur and lithium sulfide severely limit the practical application of lithium‐sulfur batteries. Herein, by introducing a designated functional organic molecule to couple with polysulfide intermediators, an endogenous prompting mechanism of sulfur conversions has thus been created leading to an alternative sulfur‐electrode process, in another words, to build a fast “internal cycle” of promotors that can promote the slow “external cycle” of sulfur conversions. The coupling‐intermediators between the functional organic molecule and polysulfides, organophosphorus polysulfides, to be the “promotors” for sulfur conversions, are not only insoluble in the electrolyte but also with higher redox‐activity. So the sulfur‐electrode process kinetics is greatly improved and the shuttle effect is eliminated simultaneously by this strategy. Meanwhile, with the endogenous prompting mechanism, the morphology of the final discharge product can be modified into a uniform covering film, which is more conducive to its decomposition when charging. Benefiting from the effective mediation of reaction kinetics and control of intermediates solubility, the lithium‐sulfur batteries can act out excellent rate performance and cycling stability.

AbstractHigh‐performance bio‐based liquid crystal copolyesters derived from 6‐hydroxy‐2‐naphthalenoic acid (HNA), 4,4′‐dihydroxybiphenyl (BP), bio‐based 2,5‐furandicarboxylic acid (FDCA) and suberic acid (Sa) were successfully designed and prepared by “one‐pot” melt polycondensation method. The influence of small amount (1–5 mol%) of FDCA on structure and properties of the copolyesters were fully investigated. Aromatic heterocyclic FDCA units had unique effect on molecular structure and properties of the copolyesters ascribed to its high stiffness and nonlinearity. The glass transition temperature, melting temperature and initial decomposition temperature of the copolyester was improved. In addition, a small amount of FDCA addition was conducive to crystallization, which can be attributed to FDCA addition increasing the molecular chain interaction. The copolyesters exhibited a broad liquid crystal phase temperature range and viscous behavior, which provided great convenience for its melt processing. The tensile strength and modulus of injected splines were in range of 82.38 ~ 121.30 MPa and 2.68 ~ 3.95 GPa, respectively, which were much higher than those of PET, PLA and other biobased polyesters. The obtained copolyester has good thermal stability, melt processing ability, mechanical properties and hydrophilicity, which indicates that they have great potential for medical and packaging applications.

AbstractPsychrophiles are cold‐adapted microorganisms living in cold regions and are known to generate cold‐active enzymes such as proteases, lipases, and peptidases. These types of enzymes are a major part of the market of the food and textile sector. This study aimed to isolate and characterize the cold‐active and detergent‐stable, extracellular protease from psychotrophic bacteria Serratia sp. TGS1 (OQ654005). Protease was purified by gel permeation chromatography using Sephadex G‐75. The specific activity of the purified protease was 250 U/mg at 15°C, with a purification fold of 5.68 and a percentage yield of 60%. The cold active protease was stable within a temperature range of 5–30°C and a pH range of 6–10. Ca+2 and Mg+2 enhanced its activity while chelators like ethylenediaminetetraacetic acid inhibited cold active protease, showing it as metalloprotease in nature. The enzyme was sensitive to Cu+2, Zn+2, and Hg+2, and the proteolytic activity decreased upon treatment with heavy metals. The molecular weight of the protease was estimated to be 47 kDa using sodium dodecyl sulfate (SDS)‐polyacrylamide gel electrophoresis. Proteins within a specific range of molecular weight possess desirable properties for industrial enzyme use. By working on a specific range, the researchers intended to examine an enzyme to examine its specific characteristics. The purified protease showed high stability to detergents like SDS, Tween 20, Tween 60, and Triton X. The maximum velocity Vmax and Km values were 59.90 mg/min/mL and 1.53 mg/mL, respectively. The obtained protease exhibited an interesting activity at a broad range of pH (6–10) and stability at low temperatures (5–30°C) and detergents. Such enzymatic features of versatile and potent cold‐active enzymes enhance their industrial applications to meet food, dairy, and laundry requirements.

AbstractThe novel oral complement factor 5a receptor 1 antagonist ACT‐1014‐6470 was well tolerated in single‐ and multiple‐ascending dose studies, including 24 h Holter electrocardiogram (ECG) recordings evaluating its cardiodynamics based on data from single doses of 30–200 mg and twice‐daily (b.i.d.) dosing of 30–120 mg for 4.5 days. By‐time point, categorical, and morphological analyses as well as concentration‐QT modeling and simulations were performed. No relevant effect of ACT‐1014‐6470 on ECG parameters was observed in the categorical and morphological analyses. After single‐dose administration, the by‐time point analysis indicated a delayed dose‐dependent increase in placebo‐corrected change from baseline in QT interval corrected with Fridericia's formula (ΔΔQTcF) at >6 h postdose. After b.i.d. dosing, ΔΔQTcF remained elevated during the 24‐h recording period, suggesting that the effect was not directly related to ACT‐1014‐6470 plasma concentration. The concentration‐QT model described change from baseline in QTcF (ΔQTcF)‐time profiles best with a 1‐oscillator model of 24 h for circadian rhythm, an effect compartment, and a sigmoidal maximum effect model. Model‐predicted ΔΔQTcF was derived for lower doses and less‐frequent dosing than assessed clinically. Median and 90% prediction intervals of ΔΔQTcF for once‐daily doses of 30 mg and b.i.d. doses of 10 mg did not exceed the regulatory threshold of 10 ms but would achieve ACT‐1014‐6470 plasma concentrations enabling adequate target engagement. Results from cardiodynamic assessments identified dose levels and dosing regimens that could be considered for future clinical trials, attempting to reduce QT liability.
Long‐term reconstruction of energy fluxes in an alpine river: Effects of flow regulation and restoration

Published: July 2023

AbstractFlow regulation of montane and alpine headwater streams can fundamentally alter food web structure and energy flows through changes in productivity, resource availability, and community assembly. Dam flow‐release schemes can be used to mitigate the environmental impacts of flow regulation via environmental flows, which can increase discharge variability and other ecologically important hydrological properties. In particular, managed floods can reintroduce disturbance to the system and stimulate the reactivation of physical habitat dynamics. However, how managed floods might restore ecosystem processes is virtually unknown. In this study, we examined patterns in potential energy fluxes before, during and after a long‐term experimental flood program on the river Spöl, a regulated alpine River in southeast Switzerland. We used benthic samples collected during long‐term monitoring and stable isotope analysis (δ13C and δ15N) of macroinvertebrates and their potential food sources to reconstruct secondary production, and potential energy fluxes, over a 20‐year study period. The experimental floods did not alter the relative importance of basal resources but resulted in a considerable decline in secondary production, which remained low after the discontinuation of the floods. Our data suggest that a lack of recolonization by mosses following the discontinuation of the experimental flood program on the river Spöl may have driven patterns in energy fluxes by limiting macroinvertebrates using mosses for habitat. The effects of environmental flows on energy flows in this system thus depend on flood disturbance and the environmental context following the discontinuation of floods.
