Published: January 2025

AbstractThe electrochemical reduction of nitrate to ammonia offers an environmentally sustainable pathway for nitrogen fixation. However, achieving both efficiency and selectivity in nitrate reduction presents a formidable challenge, due to the involvement of sluggish multielectron transfer processes. Herein, the successful synthesis of spherical Cu₂O nanoparticles (s‐Cu₂O) exhibiting significant compressive strain effects, achieved through a one‐pot method using gelatin as a structural modifier, is reported. The s‐Cu₂O catalyst demonstrates exceptional electrochemical performance for nitrate reduction reaction (NO3RR), achieving a Faradaic efficiency (FENH3) of 95.07%, ammonia selectivity of 92.03%, a nitrate conversion rate of 97.77%, and a yield rate of 284.83 µmol h⁻¹ cm⁻2 at −0.8 V versus reversible hydrogen electrode (vs. RHE) for ammonia production. Structural characterization and density functional theory calculations reveal that compressive strain plays a critical role in modulating the electronic structure of the catalyst, thereby activating the *NO intermediate in the potential determining step and effectively suppressing the hydrogen evolution reaction. Furthermore, it is implemented in a Zn‐NO3− battery, and the test results indicate that the battery achieved a peak power density of 3.95 mW cm−2 at a potential of 0.129 V (vs Zn/Zn2⁺), illustrating its excellent electrochemical and functional efficacy. This work introduces a novel strategy for the rational design of high‐performance electrocatalysts through strain engineering, offering broad implications for energy‐efficient ammonia synthesis, and sustainable nitrogen cycling.
Direct repeats found in the vicinity of intron splice sites
Authors: Rogers Scott O. , Bendich Arnold J. 
Published: January 2025

Abstract
Four main classes of introns (group I, group II, spliceosomal, and archaeal) have been reported for all major types of RNA from nuclei and organelles of a wide range of taxa. When and how introns inserted within the genic regions of genomes, however, is often unclear. Introns were examined from Archaea, Bacteria, and Eukarya. Up to 80 bp surrounding each of the 5' and 3' intron/exon borders were compared to search for direct repeats (DRs). For each of the 213 introns examined, DNA sequence analysis revealed DRs at or near the intron/exon borders, ranging from 4 to 30 bp in length, with a mean of 11.4 bp. More than 80% of the repeats were within 10 bp of the intron/exon borders. The numbers of DRs 6–30 bp in length were greater than expected by chance. When a DNA segment moves into a new genomic location, the insertion involves a double-strand DNA break that must be repaired to maintain genome stability and often results in a pair of DRs that now flank the insert. This insertion process applies to both mobile genetic elements (MGEs), such as transposons, and to introns as reported here. The DNA break at the insertion site may be caused by transposon-like events or recombination. Thus, introns and transposons appear to be members of a group of parasitic MGEs that secondarily may benefit their host cell and have expanded greatly in eukaryotes from their prokaryotic ancestors.
Health and relationship quality of sexual minorities in Europe
Authors: Berlingieri Francesco , Kovacic Matija 
Published: January 2025

Abstract
A growing body of literature investigates inequalities between sexual minorities and their heterosexual peers. This paper deals with disparities in health, health-related behaviours, and relationship quality among LGB+ individuals. We use a novel data set that allows for a wide cross-national analysis (27 EU member states) of disparities between sexual minorities and the rest of the population, as well as differences in reporting sexual orientation. We consider a rich set of social stressors, individual-specific behavioural factors, and health outcomes, as well as novel para-data (i.e., individuals’ response times) that are not available in other large surveys. The results indicate that sexual minorities are more exposed to stigma-related social stressors (both in childhood and adulthood), report worse physical and mental health conditions, feel more lonely, and are more likely to engage in coping strategies aimed at reducing or adapting to stressful conditions. Some of these findings significantly differ across gay, lesbian, and bisexual individuals and with respect to household income, the country’s enforcement of sexual minorities’ rights, and relationship status.
Diode area melting of SS316L using low power 450 nm lasers
Authors: Erman Sefer Can , Aydin Alkim , Groom Kristian , Mumtaz Kamran 
Published: January 2025

Abstract
This study investigates the use of Diode Area Melting (DAM) to process 316L stainless steel (SS316L), an alternative to Laser Powder Bed Fusion (LPBF), utilising independently addressable, low-power (~ 3.5 W) 450 nm blue lasers to address key limitations of LPBF, including thermal control, scalability, and efficiency. A normalised energy density (NED) processing map was developed to ensure successful material melting. Results demonstrated that DAM can achieve a relative density of 99.99% in single-layer SS316L samples using multiple 450 nm blue diode lasers. Notably, DAM-processed SS316L exhibited a significantly higher delta-ferrite content than samples produced via traditional LPBF, which is attributed to the slower cooling rate in DAM (600 °C/s vs. 107 °C/s). This increased delta-ferrite content enhances resistance to stress corrosion cracking in austenitic steel welds. Moreover, sub-grain cellular structures in the DAM-processed SS316L showed a 100% increase in size (4 μm) compared to those produced by LPBF.

Abstract
Research establishing factors associated with duration of mechanical ventilation after Tetralogy of Fallot repair, is mainly based on population presenting at early infancy. There are fewer reports regarding repair after infancy, during childhood and preadolescence. To compare two groups of late TOF repair based on post-operative invasive mechanical ventilation duration and explore associations with pre-operative clinical markers of severity of right ventricular outflow tract obstruction. A single-center retrospective cohort study based on medical charts review of patients older than 12 months who underwent primary complete TOF repair between 2017 and 2023. Patients younger than 12 months or those who had distinct anatomical variants were excluded. Pre-operative characteristics reflecting the severity of right ventricular outflow tract obstruction were collected, including baseline oxygen saturation, the occurrence of hypercyanotic spells, maximum right ventricular outflow tract pressure gradient. Perioperative variables included repair type, cardiopulmonary bypass and aortic cross-clamp duration, and rates of residual lesions. 280 patients from 27 countries were screened; 181 remained eligible and were significantly older than previously reported. 129 (71%) were extubated early post-operatively, while 52 (29%) had a longer ventilation course. In a multivariate analysis, only baseline oxygen saturation and repair type maintained a significant association with length of mechanical ventilation. In distinctly older patients undergoing TOF repair, those with lower base line saturation undergoing a non-valve preserving repair are more likely to have a longer course of mechanical ventilation. Other clinical markers reflecting the severity of right ventricular outflow tract obstruction were not independently associated with mechanical ventilation duration.

Published: January 2025

Abstract
Mezcal, a traditional Mexican alcoholic beverage, has been a vital source of livelihood for indigenous and rural communities for centuries. However, increasing international demand is exerting pressure on natural resources and encouraging intensive agricultural practices. This study investigates the impact of management practices (wild, traditional, and conventional) and environmental factors on the microbial communities associated with Agave angustifolia, a key species in mezcal production. High-throughput sequencing of the 16S rRNA and ITS2 gene regions revealed distinct prokaryotic and fungal community structures across different plant compartments (endosphere, episphere, and soil), identifying 8214 prokaryotic and 7459 fungal ASVs. Core microbial communities were dominated by Proteobacteria, Actinobacteria, Ascomycota, and Basidiomycota. Alpha diversity analyses showed significant increases in prokaryotic diversity from the endosphere to soil, while fungal diversity remained stable. Notably, conventional management practices were associated with reductions in beneficial microbial taxa. Environmental factors such as precipitation and temperature significantly influenced microbial diversity and composition, especially in the rhizosphere. Beta diversity patterns underscored the strong impact of plant compartment, with management practices and aridity further shaping microbial communities. These results reveal the intricate interactions between management practices, environmental conditions, and microbial diversity, providing valuable insights for the sustainable cultivation of A. angustifolia.
Lifting the Veil of Ignorance: Prison Cruelty, Sentencing Theory, and the Failure of Liberal Retributivism
Authors: Dagan Netanel , Baron Shmuel 
Published: January 2025

Abstract
Criminologists have criticized the gap between retributive theory and prison realities. In this study, we drew on qualitative findings from the Supreme Court judges of Israel to explore how judicial decision-makers construct the relationship between their retributive theory and their vision of prison life. We found that these judges perceived prison to be a disproportionate and cruel punishment. In responding to prison excessiveness, these judges constructed a “veil of ignorance” between the phases of sentencing and imprisonment by (a) re-theorizing retribution; (b) closing the gap between sentencing and prison, and (c) neutralizing responsibility. The findings shed light on the judiciary’s epistemology of prisons and its meaning for their retributive theory. In conclusion, the boundaries of retributive scholarship should be expanded to include more fully the problematic meaning of prison cruelties for judges’ philosophies and consciousness.

Published: January 2025

Abstract
The rise of populist radical right (PRR) ideas stresses the importance of understanding how individuals engage with PRR content online. However, this task is complicated by the variety of channels through which such engagement can take place. In this article, we systematically compare computational approaches for detecting PRR content in textual data. Using 66 dictionary, classic supervised machine learning, and deep learning (DL) models, we compare how these distinct approaches perform on the PRR detection task for three Germanophone test datasets and how their performance is affected by different modes of text preprocessing. In addition to individual models, we examine the performance of 330 ensemble models combining the above-mentioned approaches for the dataset with a particularly high volume of noise. Our findings demonstrate that the DL models, in combination with more computationally intense forms of preprocessing, show the best performance among the individual models, but it remains suboptimal in the case of more noisy datasets. While the use of ensemble models shows some improvement for specific modes of preprocessing, overall, it mostly remains on par with individual DL models, thus stressing the challenging nature of computational detection of PRR content.
Detection and quantification of drugs on banknotes by LC–MS/MS with a fast and non-destructive sample preparation: a comparison of three cities
Authors: Demirel Göksun , Erol Öztürk Yeter , Yeter Oya , Aslıyüksek Hızır 
Published: January 2025

Abstract

Purpose
The analysis of drug residues on some currencies is well-established in the literature. However, there is no published study describing the presence of drug residues on Turkish paper currency.

Methods
This study focused on the analysis of 14 drug residues present on 600 Turkish banknotes collected from three different cities: Ankara, Adana, and Istanbul. The banknotes underwent preparation by a non-destructive and straightforward extraction method using methanol. To investigate the extent of contamination a method was subsequently developed and validated for liquid chromatography triple quadrupole mass spectrometry analysis to detect and quantify the target analytes. The investigated substances included benzoylecgonine, cocaine, heroin, codeine, morphine, 6-monoacetylmorphine (6-AM), amphetamine, methamphetamine, 3,4-methylenedioxy-N-methamphetamine (MDMA), methyl 3,3-dimethyl-2-(1-(pent-4-en-1-yl)-1H-indazole-3-carboxamido)butanoate (MDMB-4EN-PINACA), N-[1-(aminocarbonyl)-2,2-dimethylpropyl]-1-butyl-1H-indazole-3-carboxamide (ADB-BUTINACA), tetrahydrocannabinol (THC), pregabalin, ketamine, and tramadol.

Results
The calculated mean concentrations per note were 475.5 ng cocaine, 660.7 ng methamphetamine, 220.4 ng benzoylecgonine, 36.5 ng ketamine, 46.0 ng amphetamine, 120.6 ng 6-AM, 22.9 ng morphine, 6.3 ng codeine, 107.4 ng THC, 1.3 ng MDMB-4en-PINACA, 1.1 ng ADB-BUTINACA and 65.9 ng MDMA. Our findings indicate that banknotes commonly circulated in the three cities were primarily contaminated with methamphetamine and cocaine.

Conclusions
This study highlights the prevalence of drug residues on banknotes and raises concerns about their potential impact. The contamination of Turkish currency with drug residues is a strong indication of the widespread use of banknotes in drug trafficking.
The Impact of Racial and Low Socioeconomic Status on the Implementation of Spinal Cord Stimulation for Chronic Pain in the United States
Authors: Howard Gabriel , Guinand Luis , Xu Eric , Kervyn Alex , Habibi Behnum 
Published: January 2025

Abstract

Objectives
This study aims to review the societal, economic, and racial factors that impact the usage of spinal cord stimulation for chronic pain. Our working hypothesis is that patients of ethnic minority groups or of lower socioeconomic status (SES) status may have lower implantation rates and usage of spinal cord stimulation (SCS).

Materials and Methods
Our study sourced publications from PubMed, Embase, and Cochrane Library on December 21st, 2023 for SCS for the purposes of pain management. Articles were excluded from the review if the study was not USA based, did not involve SCS for the purpose of pain or did not allow for the subgroup analysis. There were 1028 reports that resulted after the initial search with 184 duplicates which were removed. Six reports met the inclusion and exclusionary criteria and were included in the review.

Results
Several trends were able to be extrapolated from the pooled reviews. Orhurhu et al. found that Black and Hispanic minorities had a higher utilization rate of SCSs than their White and Asian counterparts in the inpatient setting. Jones and Missios et al. found that in the outpatient setting, White and privately insured patients were more likely to utilize SCS. Ovrom et al. observed an increased cost associated with Hispanic ethnicity and inpatient SCS utilization. Wondwossen et al. found that in the US military system White patients were more likely to receive SCS earlier in their care than Black patients. Labaran et al. concluded the Southern US completed more SCS implants, particularly in White patients with Medicare insurance.

Conclusions
White patients are recipients of SCS earlier and more frequently than minority patients in the outpatient setting. There is mixed evidence regarding inpatient SCS and how household income relates to SCS usage. Insurance type and coverage may be more accurately predictive than simple household income for SCS utilization.
Maximizing resource valorization: mono- and co-digestion of food and agricultural wastes with insights into microbial community dynamics

Published: January 2025

Abstract
The valorization of food processing waste is critical for sustainable development and circular economy frameworks. Although Turkish delight waste (D), a high-volume byproduct of the confectionery industry in Turkey, holds significant potential for valorization within the circular economy framework, this potential remains largely unexplored. This study evaluated the valorization potential of Turkish delight waste in anaerobic digester systems by co-digesting it with sunflower heads (S) and tea stalks (T), common agricultural wastes in Turkey, in addition to mono-digestion. Economic evaluations were also conducted on the products obtained at different stages of anaerobic digestion (AD). The highest methane yield of 388 mL CH4/g VS was obtained from Turkish delight waste in mono-digestion, and this substrate enhanced methane production when co-digested with the other substrates. However, co-digestion in the DST digester combining all three substrates yielded 234 mL CH4/g VS, indicating a limited synergistic effect. Metagenomic analyses revealed substrate-dependent variations in microbial community dynamics, particularly in digesters containing only Turkish delight waste. Acidogenic fermentation aimed at increasing VFA yield resulted in total acetic acid productions of 2828, 1707, and 1261 mg/L for D, DS, and DST, respectively. Economic assessments demonstrated that the value derived from VFA production was nearly double that obtained from methane production, even in cases where co-digestion resulted in lower overall yields. Thus, Turkish delight waste emerges as a promising candidate for both mono- and co-digestion in AD systems, offering a potentially more economically viable alternative to methane production through the generation of value-added chemicals such as VFAs.

Published: January 2025

Abstract
Summer tea (Camellia sinensis) is less favored due to its inferior taste compared to spring tea. The application of selenium (Se) has proven effective in enhancing tea flavor. However, the specific mechanisms underlying the Se-mediated improvement of summer tea quality remain unclear. This study examines the alteration of trace elements, the metabolome, and the transcriptome in tea plants subjected to Se treatment. Se application increased the concentrations of B, Fe, Zn, and Se in the summer tea shoots of certain cultivars. Metabolomic analysis revealed that exogenous Se elevated the levels of theanine and flavonoids while reducing the catechin bitterness taste index in most of the selected cultivars. Transcriptomic analysis further demonstrated that Se treatment modulated the expression of CsSULTRs, CsPHTs, CsIRTs, CsZIPs, and CsBOTs, indicating a potential link between the accumulation of these elements and the corresponding transporter genes. Based on qRT-PCR results, CsSULTR1.1, 1.2, and 4.1 are likely involved in Se transport. Additionally, differentially expressed genes (DEGs) were predominantly enriched in the flavonoid and amino acid biosynthesis pathways following Se treatment. In conclusion, the addition of Se enhances the flavor profile of summer tea by modulating genes participating in flavonoid and amino acid metabolism, underpinning its potential for improving summer tea quality.
A RIGID KUREPA TREE FROM A FREE SUSLIN TREE
Authors: KRUEGER JOHN 
Published: January 2025

Abstract
We analyze a countable support product of a free Suslin tree which turns it into a highly rigid Kurepa tree with no Aronszajn subtree. In the process, we introduce a new rigidity property for trees, which says roughly speaking that any non-trivial strictly increasing function from a section of the tree into itself maps into a cofinal branch.
THE SHORT EXACT SEQUENCE IN DEFINABLE GALOIS COHOMOLOGY

Published: January 2025

Abstract
In [2], Pillay introduced definable Galois cohomology, a model-theoretic generalization of Galois cohomology. Let M be an atomic and strongly

$\omega $

-homogeneous structure over a set of parameters A. Let B be a normal extension of A in M. We show that a short exact sequence of automorphism groups

$1 \to \operatorname {\mathrm {Aut}}(M/B) \to \operatorname {\mathrm {Aut}}(M/A) \to \operatorname {\mathrm {Aut}}(B/A) \to 1$

induces a short exact sequence in definable Galois cohomology. We also discuss compatibilities with [3]. Our result complements the long exact sequence in definable Galois cohomology developed in [4].
Mobilization and recycling of intracellular phosphorus in response to availability
Authors: Chiang Chih-Pin , Yayen Joseph , Chiou Tzyy-Jen 
Published: January 2025

Abstract
Phosphorus (P) is a non-renewable resource that limits plant productivity due to its low bioavailability in the soil. Large amounts of P fertilizer are required to sustain high yields, which is both inefficient and hazardous to the environment. Plants have evolved various adaptive responses to cope with low external P availability, including mobilizing cellular P through phosphate (Pi) transporters and recycling Pi from P-containing biomolecules to maintain cellular P homeostasis. This mini-review summarizes the current research on intracellular P recycling and mobilization in response to P availability. We introduce the roles of Pi transporters and the P metabolic enzymes and expand on their gene regulation and mechanisms. The relevance of these processes in the search for targets to improve phosphorus use efficiency and some of the current challenges and gaps in our understanding of P starvation responses are discussed.
