On face value: a ghost driver field study investigating interactions between pedestrians and a driverless vehicle with anthropomorphic displays.

In a novel, on-road study, using a 'Ghost Driver' to emulate an automated vehicle (AV), we captured over 10 hours of video (n = 520) and 64 survey responses documenting the behaviour and attitudes of pedestrians in response to the AV. Three prototype external human-machine interfaces (eHMIs) described the AV's behaviour, awareness and intention using elements of anthropomorphism: High (human face), Low (car motif), Abstract (partial representation of human features that lacked precise visual reference); these were evaluated against a (no eHMI) baseline. Despite many pedestrians reporting that they still relied on vehicular cues to negotiate their crossing, there was a desire/expectation expressed for explicit communication with future AVs.

Scale-Up of Continuous Metallaphotoredox Catalyzed C-O Coupling to a 10 kg-Scale Using Small Footprint Photochemical Taylor Vortex Flow Reactors.

We report the development and optimization of a scalable flow process for metallaphotoredox (Ir/Ni) C-O coupling, a mild and efficient approach for forming alkyl-aryl ethers, a common motif in medicinal and process chemistry settings. Time-resolved infrared spectroscopy (TRIR) highlighted the amine as the major quencher of the photocatalyst triplet excited state, along with the formation of an Ir(II) species that, in the presence of the Ni cocatalyst, has its lifetime shortened, suggesting reductive quenching of Ir(III)*, followed by reoxidation facilitated by the Ni cocatalyst. TRIR and batch reaction screening was used to develop conditions transferrable to flow, and many processing benefits of performing the reaction in flow were then demonstrated using a simple to construct/operate, small-footprint FEP coil flow reactor, including short (<10 min) space times and reduced catalyst loadings (down to 0.

Hormetic response to pesticides in diapausing bees.

Pollinators face declines and diversity loss associated with multiple stressors, particularly pesticides. Most pollination services are provided by annual bees that undergo winter diapause, and many common pesticides are highly soluble in water and move through soil and plants where bees hibernate and feed, yet the effects of pesticides on pollinators' diapause survival and performance are poorly understood. Pesticides may have complex effects in bees, and some were shown to induce hormetic effects on various traits characterized by high-dose inhibition coupled with low-dose stimulation.

Probing Surface Reactions on Multicomponent Glass Using Reflection-Absorption Infrared Spectroscopy.

The chemical reactivity of glass surfaces is often studied with elemental analysis techniques, and although such characterization methods provide insights on compositional changes from exposure to specific chemical conditions, molecule-specific chemical reactions are not determined unambiguously. This study demonstrates the use of reflection-absorption infrared spectroscopy (RAIRS) to detect molecular species on alkali-free boroaluminosilicate and alkali aluminosilicate glasses, using acetic acid vapor as a model reactant to probe reaction sites at the surface with or without pretreatment by aqueous solutions of varied pH. With the assistance of the theoretical calculation of spectral changes based on refractive indices of bulk materials, it was possible to identify the molecular species being removed and produced at the glass surface.

Food availability has direct and delayed effects on structural growth and body reserves in garter snakes.

Phenotypic plasticity in body growth enables organisms to cope with unpredictable paucities in resource availability. Growth traits influence survival and reproductive success, and thereby, population persistence, and early-life resource availability may govern lifetime patterns in growth, reproductive success, and survival. The influence of early-life environment is decidedly consequential for indeterminately growing ectotherms, which rely on available resources and ambient temperatures to maximize fitness throughout life.

Application of predictive modeling tools for the identification of Ocimum spp. herbal products.

Species identification of botanical products is a crucial aspect of research and regulatory compliance; however, botanical classification can be difficult, especially for morphologically similar species with overlapping genetic and metabolomic markers, like those in the genus Ocimum. Untargeted LC-MS metabolomics coupled with multivariate predictive modeling provides a potential avenue for improving herbal identity investigations, but the current dearth of reference materials for many botanicals limits the applicability of these approaches. This study investigated the potential of using greenhouse-grown authentic Ocimum to build predictive models for classifying commercially available Ocimum products.

Patterns of Maternal Single and Polysubstance Use in the US: A Latent Class Analysis.

Objective: Substance use patterns vary considerably in the general population, yet little is known about patterns before and during pregnancy. The purpose of this study was to describe single substance and polysubstance use (PSU) before and during pregnancy among recent births in the United States (US) and compare exposure patterns.

Methods: We used data from the Pregnancy and Risk Assessment Monitoring System (PRAMS) postpartum survey for 2016-2018 to estimate the prevalence and identify patterns of substance use by participants one to three months before and during pregnancy.

BubbleCam: Engaging Privacy in Remote Sighted Assistance.

Remote sighted assistance (RSA) offers prosthetic support to people with visual impairments (PVI) through image- or video-based conversations with remote sighted assistants. While useful, RSA services introduce privacy concerns, as PVI may reveal private visual content inadvertently. Solutions have emerged to address these concerns on image-based asynchronous RSA, but exploration into solutions for video-based synchronous RSA remains limited.

Racial-Ethnic Stratification in Work-Family Arrangements among Black, Hispanic, and White Couples.

Objective: This article builds on work-family scholarship to document racial-ethnic variation in couples' work-family arrangements, i.e., how couples respond to their work and family demands.

A Cell Autonomous Free fatty acid receptor 4 - ChemR23 Signaling Cascade Protects Cardiac Myocytes from Ischemic Injury.

Acute myocardial infarction (AMI) causes ischemic damage and cardiac remodeling that ultimately progresses into ischemic cardiomyopathy (ICM). Coronary revascularization reduces morbidity and mortality from an MI, however, reperfusion also induces oxidative stress that drives cardiac myocyte (CM) dysfunction and ICM. Oxidative stress in CMs leads to reactive oxygen species (ROS) production and mitochondrial damage.

Polymeric Anti-Antibiotic Microparticles to Prevent Antibiotic Resistance Evolution.

Vancomycin (VAN) and daptomycin (DAP) are among the last-resort antibiotics for treating multidrug-resistant Gram-positive bacterial infections. They are administered intravenously (IV); however, ≈5 - 10% of the total IV dose is released in the gastrointestinal (GI) tract via biliary excretion, driving resistance emergence in commensal Enterococcus faecium (E. faecium) populations.

Water insecurity is associated with sugar-sweetened beverage consumption in a small-scale population in Lowland Bolivia experiencing lifestyle changes.

Background: Emerging evidence indicates water insecurity (WI) is detrimental to nutritional outcomes and dietary choices.

Objective: This study measured WI experiences alongside market and traditional sugar-sweetened beverage (SSB) consumption in a small-scale society experiencing early stages of the nutrition transition (i.e.

Distribution and bioconcentration of semivolatile organic compounds (SVOCs) in soils and vascular plant Colobanthus quitensis from Sub-Antarctic and Antarctic regions.

Semi-volatile organic compounds (SVOCs) are widely distributed across the globe, including polar regions. This study investigates the distribution and bioconcentration of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in soils and Colobanthus quitensis, while also estimating potential emission sources. Results indicated high concentrations of PAHs in soils and plants from the Sub-Antarctic region, while OCPs and PCBs were more prevalent in the Antarctic region, with higher contaminant concentrations found in soils than in plant tissues.

A Method that Maintains Accuracy in the Prediction of Vitamin A Total Body Stores when Population-Based Modeling of a Limited Number of Theoretical Subjects Is Used with Retinol Isotope Dilution.

Background: Retinol isotope dilution (RID) equations are used to predict vitamin A total body stores (TBS). Including population-based ("super-subject") modeling with RID provides group-specific values for the equation coefficients.

Objectives: Objective was to test an approach that would accommodate a limited super-subject sample size without compromising accuracy in RID predictions of TBS.

Thermoelectric porous laser-induced graphene-based strain-temperature decoupling and self-powered sensing.

Despite rapid developments of wearable self-powered sensors, it is still elusive to decouple the simultaneously applied multiple input signals. Herein, we report the design and demonstration of stretchable thermoelectric porous graphene foam-based materials via facile laser scribing for self-powered decoupled strain and temperature sensing. The resulting sensor can accurately detect temperature with a resolution of 0.

Characterizing the within-person variability of food insecurity in everyday life.

Food insecurity (FI), the lack of access to adequate food, is linked with negative health and psychological outcomes. FI is typically measured retrospectively over the last year; although this measurement is useful to understand FI prevalence to inform broad policy, it leaves the experience of FI in everyday life poorly understood. Understanding how FI varies across shorter periods of time (days or weeks) can help inform FI prevention and/or intervention.

Insecticides may facilitate the escape of weeds from biological control.

Background: Preventative pesticide seed treatments (hereafter preventative pest management or PPM) are common corn and soybean treatments, and often include both fungicides and neonicotinoid insecticides. While PPM is intended to protect crops from soil-borne pathogens and early season insect pests, these seed treatments may have detrimental effects on biological control of weed seeds by insects.

Methods: Here, in two 3-year corn-soy rotations in Pennsylvania USA, we investigated a PPM approach to insect management compared to an integrated pest management approach (IPM) and a "no (insect) pest management" (NPM) control.

Recovery of Complex Isolates Including Pre-Extensively Drug-Resistant Strains From Cattle at a Slaughterhouse in Chennai, India.

Background: India has the highest global burden of human tuberculosis (TB) and the largest cattle herd with endemic bovine TB (bTB). However, the extent of cross-species transmission and the zoonotic spillover risk, including drug-resistant complex (MTBC) strains circulating in cattle, remain uncharacterized.

Methods: To address this major knowledge gap, we investigated tissue samples from 500 apparently healthy cattle at a slaughterhouse in Chennai, India.

Humanized Candida and NanoBiT Assays Expedite Discovery of Bdf1 Bromodomain Inhibitors With Antifungal Potential.

The fungal Bromodomain and Extra-Terminal (BET) protein Bdf1 is a potential antifungal target against invasive fungal infections. However, the need to selectively inhibit both Bdf1 bromodomains (BDs) over human orthologs and the lack of molecular tools to assess on-target antifungal efficacy hamper efforts to develop Bdf1 BD inhibitors as antifungal therapeutics. This study reports a phenyltriazine compound that inhibits both Bdf1 BDs from the human fungal pathogen Candida glabrata with selectivity over the orthologous BDs from the human BET protein Brd4.

Female oviposition decisions are influenced by the microbial environment.

In ovipositing animals, egg placement decisions can be key determinants of offspring survival. One oviposition strategy reported across taxa is laying eggs in clusters. In some species, mothers provision eggs with diffusible defence compounds, such as antimicrobials, raising the possibility of public good benefits arising from egg clustering.

The dengue disquisition: A low-cost public housing conundrum in Klang Valley, Malaysia.

Dengue remains the most rapidly advancing vector-borne disease in the world, and while the disease burden is predominantly in low-to-middle-income countries, the association with poverty remains in question. Consequently, a study was undertaken to evaluate the prevalence of anti-dengue antibodies among individuals residing in the People's Housing Program (PPR), a government-sponsored low-cost housing initiative targeting low-income earners. This type of public housing often faces challenges, including substandard housing facilities.

Universal parent-focused child sexual abuse prevention: A quasi-experimental protocol.

Background: Child sexual abuse (CSA) is a significant public health concern, and there is a lack of universal, evidence-based primary prevention interventions that extend beyond a focus solely on children. Parents remain a consistently underutilized target for primary prevention efforts aimed at mitigating CSA despite their unique relationship and close proximity to their children. CSA risk is not confined to any specific demographic, and its effects on affected children are well-documented, significantly impacting numerous dimensions of their wellbeing.
