AbstractIntroductionThere is a dire paucity of research into the burden, correlates and motives of substance use among trans young people in Australia.MethodUsing data from a national survey of Australian trans young people (N = 859, Mage = 19.4), we estimated prevalence of past 6‐month substance use (tobacco, alcohol, cannabis, other drugs) and lifetime substance use disorder diagnoses. Covariate‐adjusted multivariate logistic regression models tested associations between substance use types with 18 interpersonal factors. Open‐ended responses regarding substance use motives (n = 489) were qualitatively analysed using thematic analysis with an interpretative phenomenological approach.ResultsPrevalence of lifetime substance use disorder diagnosis was 13.5% (95% confidence interval [CI] 11.1, 16.1). Alcohol use was most reported (72.4%; 95% CI 68.9, 75.6) followed by tobacco (31.1%; 95% CI 27.7, 34.6) and cannabis (30.6%; 95% CI 27.2, 34.2). Trans women reported highest rates of alcohol and cannabis use; use of other drugs was highest among trans men. Highest risk of substance use was observed among trans youth who experienced discrimination, intimate partner abuse, peer rejection and lack of family support (adjusted odds ratios ranging 1.5 to 3.0). Four multi‐levelled themes of substance use motives were identified: circumstantial use, somatic use, feeling better about oneself and one's life, and harm reduction.Discussion and ConclusionsWhile substance use among trans young is largely circumstantial, hedonistic and altruistic, facilitating self‐exploration, friendship and community connectedness, substance use among trans young people is highly prevalent and may be used to cope with sleep difficulties, depression/anxiety and cisnormativity, including delays and waitlists for accessing gender‐affirming care.

AbstractBackgroundDespite the available treatments, pulmonary arterial hypertension (PAH) prognosis is poor.ObjectivesWe aimed to investigate the effects of the alamandine (ALA), melatonin (MEL), and ALA + MEL in PAH.MethodsThe rats were randomly divided into Control (n = 10), monocrotaline (MCT) (n = 12), ALA (n = 12), MEL (n = 12), and ALA + MEL (n = 12) groups. PAH was induced by MCT. The ALA, MEL, and ALA + MEL groups received 50 μg/kg/day ALA, 10 mg/kg/day MEL, and ALA + MEL, respectively, for 35 days. Echocardiographic and hemodynamic measurements and tissue analyses (morphometric, histopathological, ELISA, and western blot) were performed.ResultsMonotherapies, especially MEL, reduced the right ventricular (RV) systolic pressure. Only MEL increased the pulmonary artery acceleration time. MCT increased the RV/left ventricle (LV) + interventricular septum (IVS) ratio. While ALA and ALA + MEL slightly decreased the RV/(LV + IVS), MEL significantly restored it. MCT increased the tunica intima‐media (TIM) thickness, PCNA and α‐SMA of pulmonary arterioles, histopathological score (HS) (inflammatory infiltration etc.) of the lung, and RV. All treatments reduced the TIM thickness (especially MEL), PCNA, and α‐SMA. All treatments significantly decreased the HS of the lung; however, MEL and ALA + MEL produced greater benefits. All treatments attenuated the HS of RV. MCT caused a significant increase in lung lysyl oxidase (LOX) activity. All treatments restored the LOX; however, MEL and ALA + MEL provided greater improvement. While lung Nrf‐2 was increased in MCT‐treated rats, MEL reduced it.ConclusionALA, MEL, and ALA + MEL attenuate PAH and protect RV via antiproliferative, anti‐remodeling, antihypertrophic, anti‐inflammatory, and free radical scavenging (only MEL) capabilities. Overall, MEL produced the best outcomes.

AbstractIctalurid herpesvirus 1 (IcHV1) is the most significant viral agent in U.S. catfish aquaculture. Little is known regarding the genetic stability and antigenic variability of IcHV1. Herein, the genetic and antigenic diversity of IcHV1 field isolates was assessed by restriction fragment length polymorphism (RFLP) analysis and serum neutralization assays. RFLP analysis identified two distinct genotypes (IcHV1A and IcHV1B), both discrete from blue catfish alloherpesvirus (BCAHV). Neutralization assays with anti‐IcHV1 monoclonal antibody Mab‐95 indicate shared antigenic determinants for IcHV1A and IcHV1B that are absent from BCAHV, which Mab‐95 did not neutralize. Virulence assessments with representative isolates demonstrate significant differences between isolates within RFLP groups and pooled RFLP group data suggest IcHV1B (pooled survival [mean ± SE]: 58.3% ± 2.6) may be more virulent than IcHV1A (survival: 68.6% ± 2.4). Rechallenges with representative IcHV1A and IcHV1B isolates indicate a cross‐protective effect, with fish surviving initial exposure to IcHV1A or IcHV1B showing robust protection when subsequently re‐exposed to IcHV1A or IcHV1B. This work demonstrated significant differences in virulence between case isolates, identifying two discrete IcHV1 lineages, distinct from BCAHV, with similar virulence in channel and channel × blue catfish hybrids and a cross‐protective effect in catfish surviving exposure to either lineage.
Climatic disequilibrium in tree cover is frequent in protected areas worldwide — implications for conservation and restoration
Authors: Schweiger Andreas Hubert , Svenning Jens‐Christian 
Published: August 2024

AbstractMany species and ecosystems that diversified and adapted under consumer control in prehistoric times are nowadays highly threatened. Nature protection areas (PAs) form a major conservation strategy to avoid their losses. We argue that many PAs across Earth are in disequilibrium with current climatic conditions. At the same time, the main consumers of woody vegetation keeping these systems in climatic disequilibrium, that is, large‐bodied herbivores and/or fire, have strongly declined or changed in occurrence in (pre‐)historic times. Without active intervention, this lack of consumer control will cause the systems to approach climate equilibrium with major implications for baseline‐focused approaches in species and nature protection and restoration. In a global analysis we quantified the prevalence of climatic disequilibrium in PAs for all terrestrial biomes. We calculated climatic disequilibrium in PAs as the difference between actual tree cover and the potential tree cover under current climatic conditions (i.e., mean annual temperature and annual precipitation sum). We show that climatic disequilibrium conditions in tree cover are a widespread phenomenon in PAs across all biomes with highest values for the temperate grassland, tundra and taiga biomes. We argue that trophic rewilding, notably the restoration of functionally diverse large‐herbivore assemblages, would not only help maintain climatic disequilibrium states, but also reduce labour and costs for management.
A method to determine the retinal radiant exposure caused by ophthalmoscopy
Authors: Campbell Charles 
Published: August 2024

AbstractPurposeTo introduce a method to calculate retinal irradiance caused by ophthalmoscopy. This may be used to verify the compliance of an instrument with the radiation limits set by light hazard standards. The proposed method is simpler to use and less prone to error than the methods currently found in the light hazard standards.MethodsThe optical properties of the standardised human eye, specified by current light hazard standards, are used to calculate the magnification of an aerial image of the retinal surface by the combination of the optics of eye and the auxiliary lens used for ophthalmoscopy. The magnification of the aerial image is used to transform the spectral irradiance of the instrument illumination source to retinal irradiation values. The spectral irradiance of the instrument illumination source can be measured directly as the aerial image is located in the focal plane of the viewing optics of the ophthalmoscope. These spectral irradiation values are then processed using weightings specified by current light hazard standards to give a weighted irradiance which is converted directly to a retinal irradiance value.ResultsA single formula is provided to calculate the retinal irradiance using the processed, measured spectral irradiance values of the illumination source.ConclusionThe new method introduced here is simpler to use, requires fewer physical measurements and is less likely to introduce measurement error than that currently found in light hazard standards. The only physical measurement that needs to be taken is the illumination source spectral irradiance measured in the viewing focal plane of the instrument. These values are weighted using given in the light hazard standards. The combined irradiance value is then converted to retinal irradiance using the formula given in this paper.

AbstractObjectivesTo develop an automated verification workflow for transfusion compatibility testing (TCT) based on the AUTO10‐A guidelines and blood group serology characteristics and to conduct a simulated validation of the test and subtest results by assessing the appropriateness of the autoverification rules.BackgroundThe accuracy of TCT results is a fundamental prerequisite for ensuring the safety of blood transfusions. However, the verification of these results still requires manual intervention.Materials and MethodsFive autoverification rules and their standards were determined: agglutination intensity, normal results, logical relationships, delta checks and interlaboratory test comparisons. The established categories and standards for the five rules were retrospectively validated using 13 506 samples (requests) that had been manually verified in our laboratory from January 2020 to June 2023.ResultsA total of 66 638 test items were involved in the autoverification, with 3844 items violating the verification rules, resulting in a pass rate of 96.10%. Considering individual test items, four tests had a pass rate of more than 90% in both the test item result table and the test subitem result table. However, there were significant differences in the pass rates between different tests. The same conclusion can be drawn when the unit is requests. The different standards set for the agglutination intensity and the delta check in the ABO typing testing subitems showed significant differences in pass rates.DiscussionThe incorporation of manually verified results into the automated verification simulation indicated that the five rules established in this study have good applicability, and appropriate standards can lead to reasonable pass rates.

We report a synthesis of two members of recently discovered high-temperature superconductors of the 12442 family, with formula MCa2Fe4As4F2 (M = Rb, K) and transition temperatures of 32.7 and 34.6 K, respectively. Quality of the samples was assessed using X-ray powder diffraction, superconducting transitions were identified through transport and magnetic experiments. The temperature dependence of the upper critical field and vortex activation energy was investigated under magnetic fields up to 19 T. Two distinct thermally activated flux flow regimes were observed in both systems. Field dependences of activation energy $${{U}_{0}}(H)$$ indicate a change in the properties of vortex matter in these regimes and distinctly different dissipation mechanisms, reminiscent of cuprate HTSC.
n-Dimensional non-commutative GUP quantization and application to the Bianchi I model
Authors: Segreto Sebastiano , Montani Giovanni 
Published: August 2024

AbstractWe analyse a n-dimensional Generalized Uncertainty Principle (GUP) quantization framework, characterized by a non-commutative nature of the configurational variables. First, we identify a set of states which are maximally localized only along a single direction, at the expense of being less localized in all the other ones. Subsequently, in order to recover information about localization on the whole configuration space, we use the only state of the theory which exhibits maximal localization simultaneously in every direction to construct a satisfactory quasi-position representation, by virtue of a suitable translational operator. The resultant quantum framework is then applied to model the dynamics of the Bianchi I cosmology. The corresponding Wheeler–DeWitt equation is reduced to Schrödinger dynamics for the two anisotropy degrees of freedom, using a WKB representation for the volume-like variable of the Universe, in accordance with the Vilenkin scenario. The main result of our cosmological implementation of the constructed quantum theory demonstrates how the dynamics of a wave packet peaked at some point in the configuration space represented in the quasi-position variables favours as the most probable configuration exactly the initial one for a relatively long time, if compared with the ordinary quantum theory. This preference arises from the different dynamical behavior exhibited by wave packets in the two quantum theories.
Effectively flat potential in the Friedberg–Lee–Sirlin model
Authors: Kim Eduard , Nugaev Emin 
Published: August 2024

AbstractThe Friedberg–Lee–Sirlin (FLS) model is a well-known renormalizable theory of scalar fields that provides for the existence of non-topological solitons. Since this model was proposed, numerous works have been dedicated to studying its classical configurations and its general suitability for various physical problems in cosmology, quantum chromodynamics, etc. In this paper, we study how Q-balls in effective field theory (EFT) reproduce non-topological solitons in the full FLS theory. We obtain an analytical description of the simplified model and compare the results with numerical calculations and perturbation theory. We also study the condensation of charged bosons on the domain wall. A full numerical solution allows us to check the EFT methods for this problem. The latter analysis is based on the application of EFT methods to significantly inhomogeneous configurations. We give an interpretation of the results in terms of the shifted boson mass and the vacuum rearrangement.

Published: August 2024

The hard part turning process used to finish the cylindrical surfaces has some critical machining responses like tool wear with the lower quality of the machined surfaces. Minimum quantity lubrication (MQL)-based machining environment is currently considered an advanced cooling and lubrication technique. Cutting speed, feed rate, and cutting depth are considered input parameters, and the TaguchiL27 orthogonal array (OA) has been adopted as the design of the experiment. In this context, average surface roughness ([Formula: see text]), tool flank wear (VBc), cutting temperature ([Formula: see text]C), and chip morphology have been selected as measured outputs. To improve the machining performance of hardened steel, a sustainable MQL ([Formula: see text] directions) cooling system has been employed at the cutting zone. Iron–aluminum LRT 30 was considered as the base fluid for the hard turning of AISI 4340 steel by PVD (AlTiN) and CVD (TiN/TiCN/Al2O3) coating cutting inserts. The primary effects of process parameters and their influences on the measured outputs have been discussed. The dual jet MQL-based hard turning was performed at three levels of cutting speeds (80, 170, and 260[Formula: see text]m/min), feed rate (0.5, 0.1, and 0.15[Formula: see text]mm/rev), and cutting depth (0.2, 0.3, and 0.4[Formula: see text]mm) with an air pressure of 5[Formula: see text]bar and mist flow rate 50[Formula: see text]ml/h. The findings showed that PVD-coated carbide tools outperformed CVD-coated tools. The model of the measured outputs of both tools has been developed using second-order regression analysis. Utilizing ANOVA analysis, all the predictive models were observed to be significant and acceptable with larger than 90% of [Formula: see text] value.

Composite materials are combinations of distinct materials, engineered to create new materials with specific properties. Stir-casting method is used to prepare composites, it involves heating Aluminium Alloy (Al 8011) reinforced with B4C (Boron Carbide) and fly ash at 5, 10, and 15[Formula: see text]vol.%. The molten material is poured into a die to prepare the samples for testing. The composite’s density is measured by the principle of Archimedes, which decreases as the reinforcing particles increase, and then density and porosity are compared. The wear test specimen was prepared as per standard. The design model is generated by applying the RSM (Response Surface Methodology) equation with various parameters like load, sliding velocity of the pin, and track distance with values of 1–2[Formula: see text]kg, 1.5–2.5[Formula: see text]m/s, and 1000–3000[Formula: see text]m, respectively. The developed ANOVA (Analysis of Variance) result suggests that the created model is significant. The validation test was run and the results showed mean value of 0.0021356 and this value is in the 95% prediction range. The SEM (Scanning Electron Microscope) images of wear-tested composite show the delamination layers and deep groves. EDS (Energy Dispersive Spectroscopy) is used with electron microscopes to determine the chemical composition of wear out specimens. By the end of this study, it is discovered that the wear rate lowers with increasing reinforcement percentage while increasing with load and sliding velocity.

An interest in the study of the structural and optical properties of topological insulators, led to the selection of Bismuth telluride thin films. Among the topological insulators, Bismuth telluride is one of the promising materials that exhibit applications in the field of thermoelectric power generation. The films were prepared using the thermal evaporation method under vacuum conditions of [Formula: see text] mbar on glass substrates maintained at a temperature of 120∘C. The thickness of the film samples ranges from 400 Å to 1400 Å. Pure phases of Bi2Te3 with a rhombohedral structure are confirmed using X-ray Diffraction. The crystallite size was calculated using Debye–Scherrer’s formula. Structural morphology and compositions are examined using SEM and EDAX. The UV–Vis study reflects the optical behavior of the thin film samples. The absorption spectra gives the direct and allowed transition band gap of the Bi2Te3 thin film samples for various thicknesses. The band gap decreases with the increase in the thickness of the Bi2Te3 thin films, suggesting that the material has significant absorption towards the visible spectrum. The Photoluminescence (PL) emissions for Bi2Te3 thin film samples of various thicknesses are examined and analysed. Raman study reveals the presence of two active modes.

Published: August 2024

Background: Accurate syndesmotic reduction is necessary for achieving joint congruity and better functional outcomes. Radiographs alone don’t suffice, and CT scans are required for the evaluation of postoperative syndesmotic reduction. Methods: All patients who underwent ankle syndesmotic reduction and fixation from December 2019 to July 2021 were taken into the study. Predefined measurements were taken in postoperative radiographs and axial CT images were taken postoperatively. Sensitivity and specificity of X-rays when compared to CT scan were evaluated. Results: Twenty eight patients were included in the study and 13 cases were found to have syndesmotic malreduction in radiographs as per TCS and TFO in AP view and TFO and MCS measurements in mortise view. Five out of 28 cases were found to have syndesmotic malreduction in CT axial cuts as per standard anterior and posterior measurements. Hence 17.85% cases were malreduced in our study as per the gold standard (CT scan). The incidence of syndesmotic malreduction after fixation was 17.85%. Radiographs had a sensitivity of 60% and specificity of 56.5% in detecting malreduction. Conclusion: CT scan is necessary to accurately diagnose syndesmotic malreduction after open reduction and internal fixation of ankle fractures with associated syndesmotic injuries.

Purpose: Most shoulder pathologies are associated with altered scapular kinematics which is mentioned as scapular dyskinesis. Scapular mobility, especially in upward rotation, measurement is essential for diagnosis and treatment. Easy-to-use, clinically applicable 2-dimensional (2-D) measurements would show excellent intra-tester reliability. To quantify intra-tester reliability for measuring scapular upward rotation in individuals with scapular dyskinesias, the landmark palpation with a video annotation tool was used. Methods: Ten participants with scapular dyskinesis were recruited. Scapular upward rotation was measured at rest, 30°, 60°, 90°, and 120° of humeral elevation in the coronal plane both raising and lowering phases. Two trials were conducted for each arm position randomly, and an assessor took the pictures throughout. The video annotation tool (2-D Kinovia program) was used for measuring scapular upward rotation angles between days. The intra-tester reliability of scapular upward rotation was calculated. Results: This measurement technique demonstrated excellent intra-tester reliability (ICC[Formula: see text] = 0.98), range 0.96–0.99, and standard error of measurement was less than 1°. Conclusions: The findings demonstrated that using this technique to measure scapular upward rotation was reliable in subjects with scapular dyskinesis.
