Artificial intelligence for geoscience: Progress, challenges, and perspectives.

This paper explores the evolution of geoscientific inquiry, tracing the progression from traditional physics-based models to modern data-driven approaches facilitated by significant advancements in artificial intelligence (AI) and data collection techniques. Traditional models, which are grounded in physical and numerical frameworks, provide robust explanations by explicitly reconstructing underlying physical processes. However, their limitations in comprehensively capturing Earth's complexities and uncertainties pose challenges in optimization and real-world applicability.

Recovery Coach Program Implementation Across an Integrated Health System.

Peer recovery coaches (PRCs) are increasingly playing a role in helping patients with substance use disorders engage with treatment. PRCs can support and motivate patients in meeting their self-defined recovery goals, engaging in addiction treatment, navigating the health care system, and overcoming barriers to recovery. This support increases patient engagement and is cost-effective.

Hydrogen Evolution Reactivity of Pentagonal Carbon Rings and p-d Orbital Hybridization Effect with Ru.

Topological defects are inevitable existence in carbon-based frameworks, but their intrinsic electrocatalytic activity and mechanism remain under-explored. Herein, the hydrogen evolution reaction (HER) of pentagonal carbon-rings is probed by constructing pentagonal ring-rich carbon (PRC), with optimized electronic structures and higher HER activity relative to common hexagonal carbon (HC). Furthermore, to improve the reactivity, we couple Ru clusters with PRC (Ru@PRC) through p-d orbital hybridization between C and Ru atoms, which drives a shortcut transfer of electrons from Ru clusters to pentagonal rings.

A Cooperative Optimization Model for Variable Approach Lanes at Signaled Intersections Based on Real-Time Flow.

To resolve the congestion caused by imbalanced traffic at intersections, this paper establishes a model of the average delay deviation with the minimization of the average delay in the approach as the optimization objective. Then, the signal control scheme is further optimized based on the variable approach lanes setting. First, we investigate the threshold conditions for setting the VALs under different flows in a single approach direction.

Reconstruction of a robust bacterial replication module.

Chromosomal DNA replication is a fundamental process of life, involving the assembly of complex machinery and dynamic regulation. In this study, we reconstructed a bacterial replication module (pRC) by artificially clustering 23 genes involved in DNA replication and sequentially deleting these genes from their naturally scattered loci on the chromosome of Escherichia coli. The integration of pRC into the chromosome, moving from positions farther away to close to the replication origin, leads to an enhanced efficiency in DNA synthesis, varying from lower to higher.

Epigenome Reprogramming Through H3K27 and H3K4 Trimethylation as a Resistance Mechanism to DNA Methylation Inhibition in BRAFV600E-Mutated Colorectal Cancer.

Purpose: BRAFV600E-mutated colorectal cancer exhibits a strong correlation with DNA hypermethylation, suggesting that this subgroup of tumors presents unique epigenomic phenotypes. Nonetheless, 5-azacitidine, which inhibits DNA methyltransferase activity, is not efficacious in BRAFV600E colorectal cancer in vivo.

Experimental Design: We randomized and treated mice implanted with patient-derived tumor xenografts harboring BRAFV600E mutation with control, 5-azacitidine, vemurafenib (BRAF inhibitor), or the combination.

Early-stage implementation of peer-led interventions for emergency department patients with substance use disorder: Findings from a formative qualitative evaluation.

Introduction: Emergency department (ED)-based peer recovery coach (PRC) programs can improve access to substance use disorder treatment (SUD) for ED patients. As literature on early stages of PRC implementation is limited, we conducted a qualitative assessment of ED PRC program implementation from several US-based PRC programs focusing on barriers and facilitators for implementation and providing recommendations based on the findings.

Methods: We collected qualitative data from 39 key informants (peer recovery coaches, PRC program managers, ED physicians and staff, representatives of community-based organizations) via 6 focus groups and 21 interviews in February-December 2023.

Absorption, transportation, residual distribution of chiral C-dufulin in garlics and metabolism of its racemate.

Dufulin is a novel chiral plant antiviral agent. In this study, we investigated the uptake, translocation and accumulation of C-dufulin stereoisomers in different tissues of garlic via leaf introduction and root uptake. The behavior of dufulin enantiomers in plants is not stereoselective, and dufulin is more likely to be absorbed by leaves than by roots.

Cyclic Acetals as Expanding Monomers to Reduce Shrinkage.

Polarity-reversal catalysts (PRCs) for hydrogen-atom transfer reactions have been known in radical chemistry for more than 60 years but are rarely described and utilized in the field of photopolymerization up to now. Herein, we present the use of thiols in a unique dual function as thiol-ene click reagents and as polarity-reversal catalyst (PRC) for the radical-mediated redox rearrangements of benzylidene acetals. During the rearrangement reaction, cyclic benzylidene acetals are transformed into benzoate esters leading to a significant volumetric expansion to reduce thermoset shrinkage.

Protein is expressed in all major organs after intravenous infusion of mRNA-lipid nanoparticles in swine.

delivery of mRNA is promising for the study of gene expression and the treatment of diseases. Lipid nanoparticles (LNPs) enable efficient delivery of mRNA constructs, but protein expression has been assumed to be limited to the liver. With specialized LNPs, delivery to extrahepatic tissue occurs in small animal models; however, it is unclear if global delivery of mRNA to all major organs is possible in humans because delivery may be affected by differences in innate immune response and relative organ size.

Synergy of Charged Domain Walls in 2D In-Plane Polarized Ferroelectric GeS for Photocatalytic Water Splitting.

Two-dimensional (2D) ferroelectric (FE) materials have exhibited significant prospects for applications in photocatalysis due to their unique properties. However, studies of 2D FE catalysts have been mostly focused on the electric potential difference between different surfaces of out-of-plane-polarized FE materials. Herein, based on ab initio density functional calculations, we investigate the effects of in-plane (IP) polarizations on the photocatalytic water splitting process by considering the existence of charged domain walls (DWs) in the 2D FEs.

Predicting rapid progression in knee osteoarthritis: a novel and interpretable automated machine learning approach, with specific focus on young patients and early disease.

Objectives: To facilitate the stratification of patients with osteoarthritis (OA) for new treatment development and clinical trial recruitment, we created an automated machine learning (autoML) tool predicting the rapid progression of knee OA over a 2-year period.

Methods: We developed autoML models integrating clinical, biochemical, X-ray and MRI data. Using two data sets within the OA Initiative-the Foundation for the National Institutes of Health OA Biomarker Consortium for training and hold-out validation, and the Pivotal Osteoarthritis Initiative MRI Analyses study for external validation-we employed two distinct definitions of clinical outcomes: Multiclass (categorising OA progression into pain and/or radiographic) and binary.

In Vivo Cross-Linking Sheds Light on the Salmonella Divisome in Which PBP3 and PBP3 Compete for Occupancy.

Bacterial cell division is orchestrated by proteins that assemble in dynamic complexes collectively known as the divisome. Essential monofunctional enzymes with glycosyltransferase or transpeptidase (TPase) activities, FtsW and FtsI respectively, engage in the synthesis of septal peptidoglycan (sPG). Enigmatically, Salmonella has two TPases that can promote cell division independently: FtsI (PBP3) and the pathogen-specific paralogue PBP3.

Study on the corrosion behavior and mechanical response of weakly cemented sandstone in alkaline solutions.

This study examines the corrosion characteristics of weakly cemented sandstone under alkaline conditions, evaluating the effects of varying pH levels on its macroscopic degradation, micro-porosity, and mechanical properties, notably uniaxial compressive strength. Findings reveal that heightened alkalinity exacerbates rock damage, although a temporary alleviation in mass loss occurs between pH 9 and 11 due to pore clogging by complexes formed from cations like Ca2+ and Mg2+.Increased alkalinity induces marked changes in pore features, with an observed rise in pore numbers, transformation of pore shapes from elongated to more spherical, and adjustments in porosity, pore size, and roundness.

E3 ubiquitin ligase BTBD3 inhibits tumorigenesis of colorectal cancer by regulating the TYRO3/Wnt/β-catenin signaling axis.

Clinical trials and studies have implicated that E3 ubiquitin ligase BTBD3 (BTB Domain Containing 3) is a cancer-associated gene. However, the role and underlying mechanism of BTBD3 in colorectal cancer (CRC) is not fully understood yet. Herein, our study demonstrated that the mRNA and protein levels of BTBD3 were decreased in CRC tissues and associated with TYPO3 and Wnt/β-catenin pathway.

Mixture toxic mechanism of phoxim and prochloraz in the hook snout carp Opsariichthysbidens.

Pesticides are usually found as mixtures in surface water bodies, even though their regulation in aquatic ecosystems is usually approached individually. In this context, this work aimed to investigate the enzymatic- and transcriptional-level responses after the mixture exposure of phoxim (PHX) and prochloraz (PRC) in the livers of hook snout carp Opsariichthys bidens. These data exhibited that co-exposure to PHX and PRC induced an acute synergistic impact on O.

Vitamin E alleviates glyphosate-based herbicide-induced progesterone secretion inhibition and oxidative stress increase in chicken primary granulosa cells.

Glyphosate-based herbicides (GBH) are the most extensively used herbicides worldwide. Despite a presumed nondangerousness for animals, several studies reported negative effects after a GBH exposure in several animal models including birds, notably on reproductive functions. Several studies concerning the advantages of Vitamin E (VE) for antioxidant activity but also growth and reproduction have been reported in birds.

Proteomic and Phosphoproteomic Analyses during Plant Regeneration Initiation in Cotton ( L.).

Somatic embryogenesis (SE) is a biotechnological tool used to generate new individuals and is the preferred method for rapid plant regeneration. However, the molecular basis underlying somatic cell regeneration through SE is not yet fully understood, particularly regarding interactions between the proteome and post-translational modifications. Here, we performed association analysis of high-throughput proteomics and phosphoproteomics in three representative samples (non-embryogenic calli, NEC; primary embryogenic calli, PEC; globular embryos, GE) during the initiation of plant regeneration in cotton, a pioneer crop for genetic biotechnology applications.

A novel nomogram for predicting overall survival in patients with tongue squamous cell carcinoma using clinical features and MRI radiomics data: a pilot study.

Objective: Tongue squamous cell carcinoma (TSCC) accounts for 43.4% of oral cancers in China and has a poor prognosis. This study aimed to explore whether radiomics features extracted from preoperative magnetic resonance imaging (MRI) could predict overall survival (OS) in patients with TSCC.

Cancer-associated DNA hypermethylation of Polycomb targets requires DNMT3A dual recognition of histone H2AK119 ubiquitination and the nucleosome acidic patch.

During tumor development, promoter CpG islands that are normally silenced by Polycomb repressive complexes (PRCs) become DNA-hypermethylated. The molecular mechanism by which de novo DNA methyltransferase(s) [DNMT(s)] catalyze CpG methylation at PRC-regulated regions remains unclear. Here, we report a cryo-electron microscopy structure of the DNMT3A long isoform (DNMT3A1) amino-terminal region in complex with a nucleosome carrying PRC1-mediated histone H2A lysine-119 monoubiquitination (H2AK119Ub).
