In Pursuit of Low Energy Phosphorescence: Late Metal Coordination Complexes of the Planar, π-extended Bipyridyl Ligand 6,6',7,7'-Biphenanthridine.

The coordination chemistry of the planar, doubly π-extended bipyridine analog, 6,6',7,7'-biphenanthridine (p-biphe), is presented. The phenanthridine units in p-biphe are fused together at the 6- and 7- positions, and the resulting rigid ligand is compared with the more flexible parent "biphe" fused only at the 6-positions. p-Biphe is intensely fluorescent in solution with a much higher quantum yield, but, unlike biphe, at 77 K the fluorescence is not accompanied by any significant phosphorescence.

Artificial vision models for the identification of Mediterranean flora: An analysis in four ecosystems.

Object identification has been widely used in several applications, utilising the annotated data with bounding boxes to specify each object's exact location and category in images and videos. However, relatively little research has been conducted on identifying plant species in their natural environments. Natural habitats play a crucial role in preserving biodiversity, ecological balance, and overall ecosystem health.

Accelerometer-Measured Physical Activity After Mitral Valve Surgery: An Analysis of the UK Mini Mitral Randomized Controlled Trial.

Background: Wearable accelerometer devices measure free-living physical activity and sleep without relying on self-reports. Their utility to measure and compare recovery of physical function after cardiac surgery procedures has not been previously studied in the setting of a randomized controlled trial.

Methods: Data were collected during the UK (United Kingdom) Mini Mitral trial, in which patients were randomized to undergo either a sternotomy or a minimally invasive thoracoscopically guided right minithoracotomy procedure (Mini) for mitral valve repair.

Interfacial Self-Assembly of Sugars at Nanoscale Membranes Leads to Micron-Scale, Spectroscopically Ice-Like Chiral Suprastructures of Water.

Life requires chemical chiral specificity. The emergence of enantioselectivity is unknown but has been linked to diverse scenarios for the origin of life, ranging from an extraterrestrial origin to polarization-induced effects, and magnetic field-induced mineral templating. These scenarios require an originating mechanism and a subsequent enhancement step, leading to widespread chiral specificity.

Bouncing microdroplets on hydrophobic surfaces.

Intuitively, slow droplets stick to a surface and faster droplets splash or bounce. However, recent work suggests that on nonwetting surfaces, whether microdroplets stick or bounce depends only on their size and fluid properties, but not on the incoming velocity. Here, we show using theory and experiments that even poorly wetting surfaces have a velocity-dependent criterion for bouncing of aqueous droplets, which is as high as 6 m/s for diameters of 30 to 50 [Formula: see text]m on hydrophobic surfaces such as Teflon.

Maternal responsiveness to infant distress: A cross-cultural investigation in Uganda and the United Kingdom.

Maternal responses are a key factor in shaping early emotional development. However, research on how mothers respond to infant emotional signals outside of Western industrialized contexts remains limited. This study provides a longitudinal, naturalistic approach to mapping cultural variation in maternal responsiveness and its effect on infant emotional outcomes.

Modified DNA substrate selectivity by GmrSD-family Type IV restriction enzyme BrxU.

Bacteriophages (phages), viral predators of bacteria, generate selection pressure that causes bacteria to evolve defence systems. Type I, II and III restriction enzymes cleave incoming non-modified phage DNAs. Phages have evolved to defend against these restriction systems by modifying their DNA so that they are no longer suitable substrates.

Dietary niche shapes bacterial community in Indo-Pacific ants.

Ants are among the most ecologically diverse insects, especially in tropical forest ecosystems, yet what shapes their microbial associates remains poorly understood. Most research has focused on Neotropical ants, where strong microbial associations have been linked to shifts in diet-such as herbivory-and nesting ecology. In contrast, Indo-Pacific ants, which have independently evolved similar specialized lifestyles, remain largely unstudied for their microbial associations.

Remorse for discrimination: The role of group dominance in judging hate crimes against subordinate group members.

Power, especially in the court system, is a potent determinant of intergroup relationships. Blind justice being only an ideal, public opinion can influence whether harm to low power groups is considered criminal and should be prosecuted. Our experiments investigated the impact of social dominance orientation (SDO) on the perceived appropriateness of punishment for harm to subordinate group members by dominant group members.

Mourning ritual participation, subjective well-being and prosocial behaviour among the Luhya people of Kenya.

This study explores the relationship between participation in mourning rituals, well-being and prosociality within the Luhya community of western Kenya. Cooperation, essential for human success, is often reinforced through rituals that strengthen social bonds and collective identity. We hypothesized that mourning rituals enhance prosocial behaviour, and that this relationship is mediated by subjective well-being.

"I got all sorts of solitude, but that solitude wasn't mine": A mixed-methods approach to understanding aloneness during becoming a mother.

This study examines the evolving experiences of "aloneness" in first-time mothers during their transition to motherhood. While the term is often used to describe new mothers' experiences, it tends to blur distinct yet overlapping constructs such as solitude, loneliness, and social isolation. Study 1 involved qualitative interviews with 22 mothers, revealing three themes: the ambivalent companionship of a baby, the multifaceted nature of post-motherhood aloneness, and a shift in priorities that diminished both the quantity and quality of solitude.

Effects of combined aerobic and resistance exercise on arterial stiffness in middle-aged and older men with dysglycemia and dyslipidemia: A 12-week intervention study.

Background: The aim of this study was to evaluate the effects of 12-week combined aerobic and resistance exercise program on vascular function in individuals with dysglycemia and dyslipidemia.

Methods: Participants aged 45-69 years with a Body Mass Index (BMI) < 35 kg/m and abnormal blood glucose or lipid levels were included. All participants performed two aerobic training sessions and one resistance training session per week for 12 weeks.

Two-year outcomes after selective early treatment of patent ductus arteriosus with ibuprofen in preterm babies: follow-up of Baby-OSCAR-a randomised controlled trial.

Background: Children born extremely preterm are at increased risk of developmental problems and respiratory morbidity due to patent ductus arteriosus (PDA). The objective of this study was to evaluate whether early treatment of a PDA ≥1.5 mm with ibuprofen improved neurodevelopmental and respiratory outcomes at 24 months of age, corrected for prematurity.

Optimal message-passing with noisy beeps.

Beeping models are models for networks of weak devices, such as sensor networks or biological networks. In these networks, nodes are allowed to communicate only via emitting beeps: unary pulses of energy. Listening nodes have only the capability of : they can only distinguish between the presence or absence of a beep, but receive no other information.

A Wearable and Highly Sensitive PVDF-TrFE-BaTiO Piezoelectric Sensor for Wireless Monitoring of Arterial Signal.

As wearable electronics advance, there is a growing need for flexible sensors with high sensitivity to detect even the slightest mechanical stimuli for real-time monitoring across various applications. This study presents a poly-(vinylidene fluoride--trifluoroethylene) (PVDF-TrFE)-based flexible piezoelectric sensor, developed by electrospinning a composite of PVDF-TrFE and barium titanate (BaTiO). The PVDF-TrFE with 3 wt % BaTiO, referred to as PVDF-TrFE (3 wt % BTO), exhibits higher crystallinity, increased β-phase content, and enhanced piezoelectric response, achieving a pressure sensitivity of 0.

A call for research and policy into building multi-layered social resilience toward a sustainable agricultural workforce in Switzerland.

The agricultural workforce is exposed to rapidly changing working conditions due to societal, economic, political, and ecological challenges. In the Swiss farming community, poor mental wellbeing is a growing concern and research focuses on the distribution and hazards of psychological distress in farmers and their social network. This perspective benefits from insights of the first agricultural cohort in Switzerland, illustrating the complex field that farmers operate in.

Hominin glacial-stage occupation 712,000 to 424,000 years ago at Fordwich Pit, Old Park (Canterbury, UK).

Few high-latitude archaeological contexts are older than marine isotope stage (MIS) 15 and even fewer provide evidence of early human occupation during a glacial period. New discoveries at Old Park, Canterbury (UK), provide evidence of both the oldest accessible artefact-bearing sediment in northern Europe and cold-stage adaptation. Radiometric and palaeomagnetic dating places the earliest suggested occupation of this site between 773 thousand years ago (ka) and 607 ka, with hominin presence inferred during MIS 17-16.

Interrogating the limits of precedent autonomy: the anomalous exclusion of basic care from the ambit of advance decisions.

The Mental Capacity Act 2005 enables individuals to make advance decisions to refuse medical treatment once they lose mental capacity. However, scant attention has been given to the limit imposed by the Code of Practice upon the ability of an individual to refuse care, as opposed to treatment in an advance decision. This article examines the different meanings of 'basic care'.

To patent or not to patent: challenges and solutions to the patent ban on new genomic techniques plant in EU.

The Proposal for a new Regulation on plants produced by certain new genomic techniques (NGTs) embraces the deregulation of NGT plants but introduces a patent ban on them. This move has generated significant legal uncertainties and has become the focal point of a broader debate over the patentability of NGT plants. In reviewing the rationale and challenges underlying the patent ban, this article argues that the abandonment of patents diverges from established expectations.

An updated history of TDIF-PXY signalling: a study in cell fate and tissue patterning.

Non-cell autonomous signalling is a mechanism by which stem cells are maintained across the tree of life. In plants, many stem cell populations are regulated by peptide ligands related to CLAVATA3, which are secreted from one cell type and bind to the leucine-rich repeat domain of a plasma-membrane-localised receptor kinase related to CLAVATA1 in an adjacent cell type. Activation of CLAVATA1-like receptors then leads to a suite of events regulating stem cell fate.

Psychology should move from selective allyship to empowered actions to tackle global crises.

Psychology is committed to the principle of nonmaleficence (i.e., do no harm).

Egalitarian norms can deflate identity-bias link in real-life groups.

Social identity theory posits that group membership influences individual behavior by fostering a sense of belonging and promoting normative conformity within groups. While much research has shown a link between ingroup identification and ingroup bias, the role of ingroup norms in moderating this association remains less explored. Specifically, how varying norms (egalitarianism vs.

Advances in Functional Genomics for Exploring Abiotic Stress Tolerance Mechanisms in Cereals.

Climate change, population growth and the increasing demand for food and nutritional security necessitate the development of climate-resilient cereal crops. This requires first gaining mechanistic insights into the molecular mechanisms underpinning plant abiotic and biotic stress tolerance. Although this is challenging, recent conceptual and technological advances in functional genomics, coupled with computational biology, high-throughput plant phenotyping and artificial intelligence, are now aiding our uncovering of the molecular mechanisms underlying plant stress tolerance.
