Abstract
Siliciclastic sandstone composition on the island of Puerto Rico, part of the Greater Antilles, was influenced by both tectonic setting and climate. Cretaceous through Eocene volcanic and plutonic rocks on Puerto Rico formed in an oceanic-arc setting. Sandstones deposited during arc volcanism are quartz-poor lithic and feldspatholithic arenites, whose geochemistry largely matches that of the oceanic-arc volcanic and plutonic rocks on Puerto Rico. After cessation of volcanism on Puerto Rico during collision of the Greater Antilles island arc with the Bahamas Bank, an Oligocene through Holocene overlap assemblage was deposited unconformably above the arc deposits in the North Coast and South Coast basins of Puerto Rico. The overlap assemblage consists of some siliciclastic material, but largely shallow-water carbonate deposits. Siliciclastic deposition in the overlap assemblage reflects the volcanic-arc source, plus quartz derived from plutons exposed during uplift. In the Pleistocene and Holocene (and possibly earlier), poorly consolidated quartz-arenitic sands with SiO2 values from 92 to 98% were deposited in the overlap assemblage.
On geochemical tectonic-affinity diagrams, the lithic sandstones plot, as expected, in or near the fields for oceanic-arc provenance. However, the quartz-arenitic sands plot incorrectly in the passive-margin field when considering major elements, and correctly in or near the oceanic-arc field when considering trace elements. Trace elements in the quartz-arenitic sands are largely found in refractory minerals, whereas major elements in feldspars and lithic fragments are effectively removed by intense tropical weathering. Hence, future use of tectonic-affinity diagrams should rely on trace-element geochemistry.
Sandstones derived from the Sierra Nevada continental arc in California have QFL quartz fractions below 60%, even though the source magmatic arc has significant modal quartz. This observation suggests a “climate cap,” which does not “allow” formation of more quartzose sediments. In contrast, tropical weathering on Puerto Rico removes this climate cap allowing the creation of quartz-arenitic sands from a source rock containing limited quartz. It is remarkable that quartz-arenitic sands occur on Puerto Rico, sourced from a provenance area containing extremely limited quantities of modal quartz (estimated at less than 5%) in an oceanic-arc environment bounded by two active subduction zones. Quartz-arenitic sands and sandstones are not uniquely continental or of cratonal origin; chemical weathering is fundamentally important for the origin of first-cycle quartz-arenitic sands.
A model for contact and friction between beams under large deformation and sheaves
Authors: Ntarladima Konstantina , Pieber Michael , Gerstmayr Johannes 
Published: July 2023

Abstract
This work focuses on the modeling of contact between sheaves and flexible axially moving beams. A two-dimensional beam finite element is employed, based on the absolute nodal coordinate formulation (ANCF) with an improved selective reduced integration for the virtual work of elastic and viscous damping forces. For the efficient modeling of contact between flexible axially moving beams and sheaves in systems such as belt-drives or reeving systems, a number of newly developed algorithms is presented. The computation of normal contact is based on a penalty formulation using a spring-damper model, while for the efficient contact detection a bounding box which fits the exact dimensions of the finite elements is employed. For the detection and computation of contact, the beam elements are divided into linear segments. The modeling of tangential contact is based on a bristle model for friction extended for being compatible with an implicit time integration. A numerical example of a belt drive showed good convergence and agreement with analytical solutions.

Published: July 2023

Abstract
Background: The internet is a popular source of health information, and YouTube is a popular platform for sharing health-related content. However, the quality and accuracy of online health information are concerning. This study aimed to evaluate the quality of current hereditary breast cancer information on YouTube and compare with the content produced by the nonprofit organization, BC Tube.
Methods: Fifty-two videos, including five videos about hereditary breast cancer, were produced by BC Tube after peer-review by multiple medical professionals as well as review by non-medical personnel. A YouTube search using the Japanese keywords “hereditary breast cancer” and "HBOC" was conducted, and the top 100 videos were screened. The videos characteristics were analyzed. The content was evaluated using the PEMAT and DISCERN quality criteria.
Results: Eighty-five eligible videos were included in the analysis, and 50.6% were provided by public-interest organizations/companies, followed by hospitals/governments (21.2%), individual physicians (8.2%), breast cancer survivors (7.1%), and others (7.1%). Videos from public-interest organizations/companies showed the highest view counts, followed by BC Tube. The average video length tended to be shorter for BC Tube, individual physician, and cancer survivor videos. Public-interest organizations/companies received more like counts, followed by BC Tube.
Conclusions: Reliable, easy-to-understand, and widely recognized online medical information is needed. The popularity of videos does not always correspond to their quality, emphasizing the importance of quality evaluation. BC Tube provides a peer-reviewed platform to disseminate high-quality health information. We need to develop high-quality online health information and encourage the promotion of evidence-based information on YouTube.

Published: July 2023

Abstract

Background Attention deficit hyperactivity disorder (ADHD) therapies including atomoxetine, methylphenidate, and amphetamines are some of the most prescribed medications in North America. Due to their sympathomimetic action, these drugs are contraindicated in patients with a history of angle closure glaucoma (ACG). This study aims to determine the risk of ACG and open angle glaucoma (OAG) among users of these treatments.Methods This is a retrospective cohort study with a case control analysis using the PharMetrics Plus Database (IQVIA, USA). We created a cohort of new users of atomoxetine, methylphenidate, and amphetamines and they were followed to the first diagnosis of 1) ACG or OAG; or 2) end of follow up. For each case, four age-matched controls were selected. A conditional logistic regression model was used to adjust for confounders and to calculate adjusted incidence-rate-ratios (aIRRs).Results A total of 240,257 new users of the ADHD medications were identified. The mean age was 45.0 ± 19.4 years and 55% of the cohort was female. Regular users of atomoxetine and amphetamines had a higher aIRR for developing ACG compared with non-users (aIRR = 2.55 95%CI [1.20–5.43] and 2.27 95%CI [1.42–3.63], respectively); while users of methylphenidate had a higher aIRR for developing OAG (aIRR = 1.23 95%CI [1.05–1.59]).Conclusions Use of amphetamines and atomoxetine had a higher risk for ACG, while use of methylphenidate was associated with a higher risk for OAG. Given the prevalence of ADHD medication use (medically and recreationally), our current data on their associated risk of glaucoma have profound public health implications.

Abstract
With the development of computer technology, intelligent innovative design of mechanical equipment has become a popular topic. The structural design is a prerequisite for the creation of mechanical equipment. Therefore, this study focuses on the structural synthesis of planetary gear trains (PGTs), and proposes a new topological model and synthesis method of PGTs to address the existing research problems. First, the structural characteristics of PGTs are analyzed to explore the relation between their axles, gears, and planet carriers, and the corresponding topological model and the adjacency matrix expression of PGTs are provided. Then, the topological elements corresponding to the axles, gears, and gear pairs are added sequentially to the topological graph corresponding to the planet carriers, and the constraints are established based on similarity to inhibit the generation of isomorphism. Finally, all the databases of feasible PGTs are obtained through gear loop discrimination. All processes are carried out with computer assistance. The synthesis results of the PGTs with 1–3 degrees of freedom and up to 10 components are presented.
The mechanism of the transient increase of blood pressure caused by GLP-1 receptor agonist liraglutide in diabetic patients with severely impaired kidney function.
Authors: Wajdlich Małgorzata , Nowicki Michal 
Published: July 2023

Abstract
Chronic treatment with GLP-1R agonists may moderately lower blood pressure due to increased natriuresis and RAAS inhibition. Short-term effect of these drugs on blood pressure may be opposite and its mechanism remains unclear. We investigated the effect of a single dose of liraglutide on diurnal blood pressure profile, natriuresis, hydration and serum concentration of renin, aldosterone and atrial natriuretic peptide (ANP) in diabetic kidney disease (DKD). Patients and methods: 17 patients with eGFR < 30 ml/min/1.73 m2 and 17 with > 60 ml/min/1.73 m2 received in a random order a single subcutaneous dose 1.2 mg liraglutide and placebo with subsequent 24h blood pressure and natriuresis monitoring. Before and after each medication thoracic fluid index and plasma renin, aldosterone and ANP were also assessed. Results: The blood pressure load in the daytime and nighttime were significantly increased after liraglutide compared to placebo in patients with eGFR < 30 ml/min/1.73 m2. In patients with eGFR > 60 ml/min/1.73 m2 the changes of arterial pressure were comparable, while the morning surge was significantly reduced after liraglutide compared to placebo. After liraglutide 24h urine sodium excretion increased in both groups (p = 0.003) vs. placebo, the effect was greater in eGFR > 60 ml/min/1.73 m2 group (p = 0.046). Plasma ANP increased after liraglutide in both groups, significantly greater in eGFR < 30 ml/min/1.73 m2 group (p = 0.012). Only in this group serum aldosterone (p = 0.013) and thoracic fluid index (p = 0.01) decreased after liraglutide compared to placebo. Plasma renin concentration remained unchanged. Conclusions: In severe chronic kidney disease liraglutide induces a transient increase of blood pressure due to reduced natriuresis. The natriuretic effect of liraglutide in DKD depends on increased ANP and decreased aldosterone secretion.

Published: July 2023

Abstract
Polygonatum cyrtonema Hua is a perennial herb belonging to the Liliaceae family, with significant medicinal and dietary value. However, root rot， a server disease, has led to a decline in yield and quality of this species. In this study, a fungus was isolated from symptomatic samples of root rot and identified as Fusarium commune through molecular and morphological analyses. After re-isolation, the identification of F. commune as the causative agent of root rot was confirmed by fulfilling Koch's postulates in subsequent tests.. Biological characteristics indicated that the optimal growth conditions for F. commune were a temperature of 25℃, pH of 8, carbon source of soluble starch, nitrogen source of peptone, and a photoperiod of 24 hours. In order to reduce the use of chemical fungicides and explore natural substances to control the disease, the sensitivity of F. commune to seven phytochemicals was studied. Four phytochemicals showed apparent inhibitory activity and honokiol displaying the highest antifungal activity, having a 50% of the maximal effect concentration (EC50) of 8.2628 ± 0.27 mg/L. These findings provide a scientific basis for the control of root rot in P. cyrtonema Hua.

Abstract
Environmental pollution poses a significant challenge to human health, ecosystems, and the planet's sustainability. Widespread contamination of air, water, and soil from various pollutants requires effective and sustainable solutions to reduce or eliminate pollution and its impacts. In this research work, we designed novel reduced graphene oxide functionalized copper oxide (rGO-CuO) nanocomposite material through simple method. The synthesized novel rGO-CuO nanocomposite material was characterized by using various advance tools such as XRD, SEM and EDX that revealed the information about the crystalline nature, phase purity, morphological features and elemental composition. The characterized techniques confirm the successful synthesis of novel composite material. Furthermore, the synthesized material was exploited for decolorization of CR dye in aqueous environment through optimized different experimental condition such as concentration of NaBH4, sun light effect and catalytic dosage. At minimum catalyst dose of 2.4 mg in only 5 minutes the prepared catalyst exhibited 98.7% degradation of CR dye from aqueous environment. Furthermore, the exceptional reusable profile of catalyst up to 5th cycle highlights the reliability of rGO-CuO photocatalyst. The decolorization performance of rGO-CuO photocatalyst suggests that the prepared catalyst could be an effective aspirant for the degradation of other synthetic dye at commercial level.

Published: July 2023

Abstract
Plastic pollution is known to exert significant negative impacts on the entire food web which, in turn, affects humans. Microorganisms are capable of breaking down released polymers, however full degradation of polymers in situ is long-lasting, estimated to take place within hundreds to thousands of years. On the contrary, passive removal, e.g. through surface adhesion on living biota, can remediate polluters within hours to days rather than years. In this study, the potential of three filamentous fungi namely Aspergillus niger, Aspergillus terreus and Penicillium rubens was investigated to remediate polyamide particles of 5 µm size from a liquid environment. Thermogravimetric analysis revealed removal capacities of 59 to 67% within 24 to 72 hours. Microscopic examinations allowed to visualize that the particles were tightly attached to fungal hyphae, consequently overgrown by succeeding layers of mycelium to restrain particles within the fungal pellet. These findings reveal great potential for future mycelia-based applications such as regenerative and sustainable “biofilters” to clear flowing water.

Published: July 2023

Abstract
Deep geological repository is widely considered as the preferred solution for the final disposal of high-level radioactive waste. Investigation representative of the Hungarian disposal concept was conducted using mock-up diffusion cells to study the chemical changes of S235JR carbon canister and CEM II/B PURAM concrete under anerobic and water saturated conditions at 80°C. Micro-Raman, SEM-EDX, fluid and potentiometric analysis were performed over a period of 12 months. The discussion was supported by thermodynamic and reactive transport modeling. The findings revealed that a uniform corrosion process occurred, leading to rapid passivation of the C-steel with magnetite as the primary corrosion product. Modeling demonstrated that the increase in temperature to 80°C and the chemical evolution of the concrete did not significantly affect the corrosion passivation process. Although the formation of Fe-siliceous hydrogarnets is thermodynamically possible at 80°C, it did not jeopardize magnetite passivation. Overall, the results suggest that the containers would have a long lifespan under the studied disposal conditions.

Abstract
The development of human societies has altered the landscape of the watershed through remedial activities, industrialization, and urbanization, causing significant changes in a wide range of hydrological, climatic, ecological, and socio-economic functions. This, in turn, has had significant consequences on resources and ecosystems. Therefore, in this study, the water retention index, one of the indicators of multifunctional ecosystem services, was quantified using InVEST software. For this purpose, variables including rainfall, land use, soil hydrological groups, and curve numbers related to 28 watersheds in Ardabil province were prepared and introduced to InVEST software. Then, an accuracy assessment was conducted using error coefficients, including R2, RMSE, ME, and MAE. Additionally, to analyze auto-spatial correlation and identify runoff hotspots and water retention, global Moran's index and Enslin Moran's index were employed. The results showed that the minimum water retention was observed in residential areas (26.26 m3), and the maximum amount was obtained in the forest (74.43) and grassland (74.46) uses. Moreover, Barogh, Doost Bigloo, Shamsabad, Amoghin, Gilandeh, and Yamchi watersheds were ranked first, while Akbardavod watershed was ranked 28th. Generally, the southern and western parts of the province had a higher water storage capacity compared to the northern parts. Unnatural or artificial land use areas had lower water retention. Comparing the estimated runoff results with InVEST software with observational data from hydrometric stations showed that the software's estimated runoff results were acceptable, provided that the input data was produced with great accuracy. The analysis of Moran's index and hotspots identified patterns of spatial distribution of runoff volume and water retention in most watersheds, indicating significant spatial correlation between the data. The results of this research can provide a theoretical basis for the selection of InVEST software, decision-making, and regional ecosystem management.

Published: July 2023

Abstract
Considering that the regulating physical mechanism of the magnetic field on electrolytic plasma is insufficient, this study introduces a plasma discharge model to demonstrate its effect on material removal in magnetic-electrolytic plasma polishing. Firstly, we establish a mathematical model to describe plasma discharge induced by electron collision. The Boltzmann kinematic equations are employed to elucidate the physical dynamics of electrons and their momentum distribution function during ionization collisions. Secondly, we derive the surface material removal equation based on the instantaneous high-temperature melting of plasma discharge and establish the corresponding boundary conditions for simulation calculations. Subsequently, we conduct electromagnetic plasma polishing experiments under varying magnetic field intensities using TA1 titanium alloy as the test material. Our simulation results demonstrate that the magnetic field enhances the spatial electric field formed by the uneven distribution of ion electrons, expediting the plasma discharge process towards the anode and generating interference currents to counterbalance the required material removal current. Experimental data is provided to validate the model, consistently revealing a positive correlation between circuit current and material removal rate. The research demonstrates the rationality and reliability of the material removal model for plasma discharge, offering a fundamental understanding of electromagnetic plasma polishing.

Abstract

The mechanochemical GTPase dynamin-related protein 1 (Drp1) catalyzes mitochondrial fission, but the regulatory mechanisms remain ambiguous. Here we found that a conserved, intrinsically disordered, six-residue Short Linear Motif at the extreme Drp1 C-terminus, named CT-SLiM, constitutes a critical allosteric site that controls Drp1 structure and function in vitro and in vivo. Extension of the CT-SLiM by non-native residues, or its interaction with the protein partner GIPC-1, constrains Drp1 subunit conformational dynamics, alters self-assembly properties, and limits cooperative GTP hydrolysis, leading to the fission of model membranes in vitro. In vivo, the availability of the native CT-SLiM is a requirement for productive mitochondrial fission, as both non-native extension and deletion of the CT-SLiM severely impair its progression. Thus, contrary to prevailing models, Drp1-catalyzed mitochondrial fission relies on allosteric communication mediated by the CT-SLiM, deceleration of GTPase activity, and coupled changes in subunit architecture and assembly-disassembly dynamics.
