Published: August 2023

AbstractPatients on maintenance haemodialysis (MHD) face social isolation due to the far‐reaching effects of their disease and treatment. Based on the Transactional Model of Stress and Coping, we analysed the relationship between perceived stress and social isolation in patients, and the mediating role of internal health‐related locus of control (IHLC) from the perspective of co‐existence of perceived helplessness (HEL) and perceived self‐efficacy (SEL). We used structured questionnaires to investigate 332 cases of young and middle‐aged MHD patients in four tertiary hospitals in Guangdong, China. Polynomial regression and response surface analysis were conducted, along with tests of mediating effects on the data. The research was based on STROBE guidelines. The results showed that perceived stress is significantly and positively associated with social isolation. When the HEL and SEL of perceived stress were congruent, the joint effect of the two was in a positive curvilinear relationship to social isolation, when the two were incongruent, the risk of social isolation was lower for “low HEL‐high SEL” patients compared to the “high HEL‐low SEL” combination. The more congruent in HEL ‐SEL, the lower the risk of social isolation for the patients, with the IHLC playing a mediating role in this association. This study reveals that the coexistence of perceived stress's HEL and SEL affects social isolation through congruent and incongruent matching mechanism, providing additional explanations for the mechanism of occurrence of patients' social isolation.

AbstractPreparing MoS2‐based materials with reasonable structure and catalytic activity to enhance the sluggish kinetics of lithium polysulfides (LiPSs) conversion is of great significance for Li–S batteries (LSBs) but still remain a challenge. Hence, hollow nanotubes composed of N‐doped ultrathin MoS2 nanosheets (N‐MoS2 NHTs) are fabricated as efficient S hosts for LSBs by using CdS nanorods as a sacrifice template. Characterization and theoretical results show that the template effectively inhibits the excessive growth of MoS2 sheets, and N doping expands the interlayer spacing and modulates the electronic structure, thus accelerating the mass/electron transfer and enhancing the LiPSs adsorption and transformation. Benefiting from the merits, the N‐MoS2 NHTs@S cathode exhibits an excellent initial capacity of 887.8 mAh g−1 and stable cycling performances with capacity fading of only 0.0436% per cycle at 1.0 C (500 cycles). Moreover, even at high S loading that of 7.5 mg cm−2, the N‐MoS2 NHTs@S cathode also presents initial excellent areal capacity of 7.80 mAh cm−2 at 0.2 C. This study offers feasible guidance for designing advanced MoS2‐based cathode materials in LSBs.

Published: August 2023

AbstractAqueous aluminum metal batteries (AMBs) have attracted numerous attention because of the abundant reserves, low cost, high theoretical capacity, and high safety. Nevertheless, the poor thermodynamics stability of metallic Al anode in aqueous solution, which is caused by the self‐corrosion, surface passivation, or hydrogen evolution reaction, dramatically limits the electrochemical performance and hampers the further development of AMBs. In this comprehensive review, the key scientific challenges of Al anode/electrolyte interface (AEI) are highlighted. A systematic overview is also provided about the recent progress on the rational interface engineering principles toward a relatively stable AEI. Finally, suggestions and perspectives for future research are offered on the optimization of Al anode and aqueous electrolytes to enable a stable and durable AEI, which may pave the way for developing high‐performance AMBs.

Published: August 2023

AbstractImpurities found in active pharmaceutical ingredients (APIs) and pharmaceutical products are of ever‐increasing interest. According to several regulatory agencies, purity and impurity profiles are essential. An impurity is defined as any additional inorganic or organic material, residual solvents other than the medicinal components, or undesired compounds that remain with APIs. Impurities and degradation products in bulk drug materials and pharmaceutical formulations are identified, their structures are clarified, and their quantitative determination is part of impurity profiling. Unrecognized, poisonous impurities are dangerous to health and should be identified by selective procedures to increase the safety of drug therapy, and impurity profiling has become more significant in pharmaceutical analysis. This review briefly introduces process and product‐related impurities and emphasizes the creation of cutting‐edge analytical techniques for identifying them. It discusses the use of analytical methods, particularly high‐performance thin‐layer chromatography, liquid chromatography with mass spectrometry (MS), ultrahigh‐performance liquid chromatography, gas chromatography–MS, and nuclear magnetic resonance spectroscopy for the identification of contaminants and degradation products. It has discussed the importance of the quality, efficacy, and safety of drug substances and products, including the origin, types, and quality control of impurities, the need for the development of impurity profiling methods, impurity identification, and regulatory aspects.

Published: August 2023

AbstractThe process of growth, development, and reproduction cannot take place in a live body without the presence of amino acids (AAs) since they are necessary for appropriate functioning. Detection of AAs in pharmaceutical and food samples is required to ensure quality, quantity, and efficacy. The AAs generally do not contain chromophores; hence their chromatographic analysis requires derivatization. The research papers published in the last few years were used to compile this manuscript. This manuscript covers various analytical, bioanalytical, and electrochemical approaches used in the identification of AAs. The analytical techniques like high‐performance liquid chromatography, ultra‐performance liquid chromatography, etc., and the hyphenated analytical techniques like liquid chromatography‐mass spectrometry, ultra‐performance liquid chromatography‐electrospray tandem mass spectrometry, and hydrophilic interaction ultra‐performance liquid chromatography are also discussed. This manuscript also briefly outlines the electrochemical analytical techniques including sensors and biosensors. This review article will be useful to the researcher working in the area of the development of analytical techniques for the detection of AAs.

AbstractDue to ever‐increasing global energy demands and dwindling resources, there is a growing need to develop materials that can fulfil the World's pressing energy requirements. Electrochemical energy storage devices have gained significant interest due to their exceptional storage properties, where the electrode material is a crucial determinant of device performance. Hence, it is essential to develop 3‐D hierarchical materials at low cost with precisely controlled porosity and composition to achieve high energy storage capabilities. After presenting the brief updates on porous carbons (PCs), then this review will focus on the nitrogen (N) doped porous carbon materials (NPC) for electrochemical supercapacitors as the NPCs play a vital role in supercapacitor applications in the field of energy storage. Therefore, this review highlights recent advances in NPCs, including developments in the synthesis of NPCs that have created new methods for controlling their morphology, composition, and pore structure, which can significantly enhance their electrochemical performance. The investigated N‐doped materials a wide range of specific surface areas, ranging from 181.5 to 3709 m2 g−1, signifies a substantial increase in the available electrochemically active surface area, which is crucial for efficient energy storage. Moreover, these materials display notable specific capacitance values, ranging from 58.7 to 754.4 F g−1, highlighting their remarkable capability to effectively store electrical energy. The outstanding electrochemical performance of these materials is attributed to the synergy between heteroatoms, particularly N, and the carbon framework in N‐doped porous carbons. This synergy brings about several beneficial effects including, enhanced pseudo‐capacitance, improved electrical conductivity, and increased electrochemically active surface area. As a result, these materials emerge as promising candidates for high‐performance supercapacitor electrodes. The challenges and outlook in NPCs for supercapacitor applications are also presented. Overall, this review will provide valuable insights for researchers in electrochemical energy storage and offers a basis for fabricating highly effective and feasible supercapacitor electrodes.

Published: August 2023

AbstractBackgroundFormaldehyde (FA) is associated with the occurrence of leukemia, and oxidative stress is considered to be a major reason. As an endogenous biomarker of oxidative stress, few studies focus on the relationship between peroxiredoxin III (PrxIII) and FA toxicity. Our previous research observed high expression of PrxIII occurred in the process of apoptosis of bone marrow cells (BMCs) induced by FA, however the exact mechanism is unclear. Therefore, this paper aimed to explore the possible association between FA toxicity and PrxIII gene.MethodsWe first, used a Cell Counting Kit‐8 (CCK‐8) to detect the viability of BMCs after they were exposed to different doses of FA (50, 100, 200 μmol/L) for different exposure time (12, 24, 48 h), then chose 24 h as an exposure time to detect the expression of PrxIII for exposing different doses of FA by Quantitative reverse transcription‐PCR (qRT‐PCR) and Western blot analysis. Based on our preliminary experimental results, we chose 100 μmol/L FA as an exposure dose to expose for 24 h, and used a small interfering RNA (siRNA) to silenced PrxIII to examine the cell viability by CCK‐8, reactive oxygen species (ROS) level by DCFH‐DA, apoptosis by Annexin V/PI double staining and cell cycle by flow cytometry (FCM) so as to explore the possible regulatory effect of PrxIII silencing on FA‐induced bone marrow toxicity.ResultsHigh expression of PrxIII occurred in the process of FA‐induced oxidative stress. Silencing of PrxIII prevented FA from inducing oxidative stress, thus increasing cell viability, decreasing ROS level, rescuing G0–G1 and G2–M arrest, and reducing cell apoptosis.ConclusionPrxIII silencing might be a potential target for alleviating FA‐induced oxidative damage.

However, in an April 2023 guidance document, the Student Privacy Policy Office explained that “information that a school official obtains through personal knowledge or observation . . . is generally not protected by FERPA's limitations on the disclosure of education records, even if that information is also contained in an education record.” (Student Privacy Policy Office, Guidance for School Officials on Student Health Records (April 12, 2023).
The First Quaternary Phase of the NbRuB Structure Type: Experimental and Computational Investigations of TiFe1.3Os3.9B2.8
Authors: Gibson Kate A. , Küpers Michael , Fokwa Boniface P. T. 
Published: August 2023

AbstractThe novel composition – TiFe1.3Os3.9B2.8 – is the first quaternary phase of the NbRuB structure type. The layer‐like structure consists of boron (mixed with 8 % Fe) dumbbells in the same layer as osmium atoms, some sites with mixed occupancies. The second layer has isolated boron, osmium/titanium (51 % Os) and iron atoms. The presence of iron enables the study of magnetism as Fe‐chains are present, with intra‐ and interchain distances of 3.02 Å and 5.76 Å, respectively. Density functional theory (DFT) predicts magnetic ordering to be likely with the antiferromagnetic ground state only 13 meV more favorable than the ferromagnetic state. This discovery opens the possibilities of studying various quaternary compositions in the superconducting NbRuB structure type.

Published: August 2023

AbstractThe DCAT Application Profile for Data Portals is a crucial cornerstone for publishing and reusing Open Data in Europe. It supports the harmonization and interoperability of Open Data by providing an expressive set of properties, guidelines, and reusable vocabularies. However, a qualitative and accurate implementation by Open Data providers remains challenging. To improve the informative value and the compliance with RDF-based specifications, we propose a methodology to measure and assess the quality of DCAT-AP datasets. Our approach is based on the FAIR and the 5-star principles for Linked Open Data. We define a set of metrics, where each one covers a specific quality aspect. For example, if a certain property has a compliant value, if mandatory vocabularies are applied or if the actual data is available. The values for the metrics are stored as a custom data model based on the Data Quality Vocabulary and is used to calculate an overall quality score for each dataset. We implemented our approach as a scalable and reusable Open Source solution to demonstrate its feasibility. It is applied in a large-scale production environment (data.europa.eu) and constantly checks more than 1.6 million DCAT-AP datasets and delivers quality reports.
A spectral metric for collider geometry
Authors: Larkoski Andrew J. , Thaler Jesse 
Published: August 2023

Abstract
By quantifying the distance between two collider events, one can triangulate a metric space and reframe collider data analysis as computational geometry. One popular geometric approach is to first represent events as an energy flow on an idealized celestial sphere and then define the metric in terms of optimal transport in two dimensions. In this paper, we advocate for representing events in terms of a spectral function that encodes pairwise particle angles and products of particle energies, which enables a metric distance defined in terms of one-dimensional optimal transport. This approach has the advantage of automatically incorporating obvious isometries of the data, like rotations about the colliding beam axis. It also facilitates first-principles calculations, since there are simple closed-form expressions for optimal transport in one dimension. Up to isometries and event sets of measure zero, the spectral representation is unique, so the metric on the space of spectral functions is a metric on the space of events. At lowest order in perturbation theory in electron-positron collisions, our metric is simply the summed squared invariant masses of the two event hemispheres. Going to higher orders, we present predictions for the distribution of metric distances between jets in fixed-order and resummed perturbation theory as well as in parton-shower generators. Finally, we speculate on whether the spectral approach could furnish a useful metric on the space of quantum field theories.

AbstractIron-dependent lipid peroxidation causes ferroptosis, a form of regulated cell death. Crucial steps in the formation of ferroptosis include the accumulation of ferrous ions (Fe2+) and lipid peroxidation, of which are controlled by glutathione peroxidase 4 (GPX4). Its crucial role in stopping the spread of cancer has been shown by numerous studies undertaken in the last ten years. Epithelial–mesenchymal transition (EMT) is the process by which epithelial cells acquire mesenchymal characteristics. EMT is connected to carcinogenesis, invasiveness, metastasis, and therapeutic resistance in cancer. It is controlled by a range of internal and external signals and changes the phenotype from epithelial to mesenchymal like. Studies have shown that mesenchymal cancer cells tend to be more ferroptotic than their epithelial counterparts. Drug-resistant cancer cells are more easily killed by inducers of ferroptosis when they undergo EMT. Therefore, understanding the interaction between ferroptosis and EMT will help identify novel cancer treatment targets. In-depth discussion is given to the regulation of ferroptosis, the potential application of EMT in the treatment of cancer, and the relationships between ferroptosis, EMT, and signaling pathways associated with tumors. Invasion, metastasis, and inflammation in cancer all include ferroptosis and EMT. The goal of this review is to provide suggestions for future research and practical guidance for applying ferroptosis and EMT in clinical practice.

AbstractFor fixed sequences$$u = (u_i)_{i\in {{\mathbb {N}}}}, \varphi =(\varphi _i)_{i\in {{\mathbb {N}}}}$$u=(ui)i∈N,φ=(φi)i∈N, we consider the weighted composition operator$$W_{u,\varphi }$$Wu,φwith symbols$$u, \varphi $$u,φdefined by$$x=(x_i)_{i\in {{\mathbb {N}}}}\mapsto u(x\circ \varphi )= (u_ix_{\varphi _i})_{i\in {{\mathbb {N}}}}$$x=(xi)i∈N↦u(x∘φ)=(uixφi)i∈N. We characterize the continuity and the compactness of the operator$$W_{u,\varphi }$$Wu,φwhen it acts on the weighted Banach spaces$$l^p(v)$$lp(v),$$1\le p\le \infty $$1≤p≤∞, and$$c_0(v)$$c0(v), with$$v=(v_i)_{i\in {{\mathbb {N}}}}$$v=(vi)i∈Na weight sequence on$${{\mathbb {N}}}$$N. We extend these results to the case in which the operator$$W_{u,\varphi }$$Wu,φacts on sequence (LF)-spaces of type$$l_p(\mathcal {V})$$lp(V)and on sequence (PLB)-spaces of type$$a_p(\mathcal {V})$$ap(V), with$$p\in [1,\infty ] \cup \{0\}$$p∈[1,∞]∪{0}and$$\mathcal {V}$$Va system of weights on$${{\mathbb {N}}}$$N. We also characterize other topological properties of$$W_{u,\varphi }$$Wu,φacting on$$l_p(\mathcal {V})$$lp(V)and on$$a_p(\mathcal {V})$$ap(V), such as boundedness, reflexivity and to being Montel.
The privacy dependency thesis and self-defense
Authors: Munch Lauritz Aastrup , Mainz Jakob Thrane 
Published: August 2023

AbstractIf I decide to disclose information about myself, this act may undermine other people’s ability to conceal information about them. Such dependencies are called privacy dependencies in the literature. Some say that privacy dependencies generate moral duties to avoid sharing information about oneself. If true, we argue, then it is sometimes justified for others to impose harm on the person sharing information to prevent them from doing so. In this paper, we first show how such conclusions arise. Next, we show that the existence of such a dependency between the moral significance you are inclined to attribute to privacy dependencies and judgments about permissible self-defense puts pressure on at least some ways of spelling out the idea that privacy dependencies ought to constrain our data-sharing conduct.
