Linking Foraging Behaviour and Habitat Preferences During Moult Across Multiple Populations of Red-Throated Diver.

Understanding the habitat use of individuals can facilitate methods to measure the degree to which populations will be affected by potential stressors. Such insights can be hard to garner for marine species that are inaccessible during phases of their annual cycles. Here, we quantify the link between foraging habitat and behaviour in an aquatic bird of high conservation concern, the red-throated diver () across three breeding populations (Finland, Iceland and Scotland) during their understudied moult period.

Influence of Strong Molecular Vibrations on Decoherence of Molecular Polaritons.

We derive the transition rates, dephasing rates, and Lamb shifts for a system consisting of many molecules collectively coupled to a resonant cavity mode. Using a variational polaron master equation, we show that strong vibrational interactions inherent to molecules give rise to multi-phonon processes and suppress the light-matter coupling. In the strong light-matter coupling limit, multiphonon contributions to the transition and dephasing rates strongly dominate over single-phonon contributions for typical molecular parameters.

Balance correlations, agentic zeros, and networks: The structure of 192 years of war and peace.

Social network extensions of Heider's balance theory have led to a plethora of adaptations, often inconsistent with Heider and each other. We present a general model that permits the description and testing of specific balance theoretic predictions as Heider had originally proposed them. We formulate balance statements as a comparison of two conditional probabilities of a tie: [Formula: see text], conditioned on 2-path relations [Formula: see text] vs.

Evidence of microcystin bioaccumulation and its effects on structural alterations in various shrimp (Litopenaeus vannamei Boone, 1931) tissues from shrimp aquaculture in the northern coastal region of East Java, Indonesia.

Microcystins are generated by diverse cyanobacteria in shrimp ponds marked by high nutrient levels. The study examined microcystin-leucine arginine (MC-LR) in the pond water, gills, hepatopancreas, and muscle of shrimp (Litopenaeus vannamei) from shrimp ponds on the northern coast of East Java and its effects on their histological structures. In shrimp ponds dominated by cyanobacteria particularly Microcystis and Oscillatoria, MC-LR levels were high.

Active and passive organic carbon fluxes during a bloom in the Southern Ocean (South Georgia).

The Controls Over Mesopelagic Interior Carbon Storage (COMICS) cruise DY086 took place aboard the RRS Discovery in the South Atlantic during November and December, 2017. Physical, chemical, biogeochemical and biological data were collected during three visits to ocean observatory station P3, off the coast of South Georgia, during an austral spring bloom. A diverse range of equipment including CTD-rosette, Acoustic Doppler Current Profiler (ADCP), net deployments, marine snow catchers (MSCs), Stand Alone Pump System (SAPS) and PELAGRA Sediment Traps were used to produce a comprehensive, high-quality dataset.

The myth of a cancer-specific temperament: An analysis of affective temperament in cancer patients.

Objective: We investigate the prevalence of five affective temperaments (depressive, cyclothymic, hyperthymic, irritable, and anxious) in a large sample of cancer patients and associations of temperament with cancer site as well as the impact of temperament on overall survival of cancer patients.

Methods: Data for this prospective cohort study was collected in the outpatient clinic of a large cancer center. We used the Temperament Evaluation in Memphis, Pisa and San Diego - Münster Version (TEMPS-M) and recorded patient data.

Review of challenges and key enablers in energy systems towards net zero target: Renewables, storage, buildings, & grid technologies.

Carbon emissions are increasing due to continued urban developments and the growth of the human population, leading to environmental issues such as global warming. Moving towards the future, projected population growth will cause an increase in energy demand. Without the transition to cleaner energy generation, a high dependency on electricity generation by fossil fuels will emit more harmful gases, worsening the impacts of global warming.

Daily health and well-being in adulthood and old age: The role of adverse childhood experiences.

How susceptible our daily affect is to fluctuations in physical health indicates how well we adapt to everyday health challenges. Adverse childhood experiences (ACEs) are known to have a lasting impact on everyday emotion regulation and adaptation across the lifespan, but less is known about whether and how such adversity is linked to the susceptibility of affect to everyday health challenges. This study therefore tested whether ACEs were associated with daily reports of positive and negative affect and examined weather they moderated emotional reactions to daily physical symptoms in adulthood and old age.

Novel Hierarchical Disordered Li- and Al-KIL-2 Catalysts for the Pyrolysis of Biomass Model Compounds and Wool Waste: A Comparison with ZSM-5.

In this study, we investigated the pyrolysis of cellulose, lignin, phenylalanine and textile wool waste using microscale thermogravimetric analysis (TGA) and a gram-scale fixed bed reactor. The pyrolysis was conducted at 500 °C and 1 bar N, using Al- and Li-doped mesoporous KIL-2 and ZSM-5 catalysts for comparison. Our results show that amorphous Al-KIL-2 catalyst was the most efficient in producing aromatics from cellulose and lignin.

Excitation of filamentous growth in dekkera spp. By quorum sensing aromatic alcohols 2-phenylethanol and tryptophol.

Fungi from the genus Dekkera, also known as Brettanomyces, are significant contaminants in commercial beer and wine production, and when present unintentionally, these non-domesticated yeasts result in the development of undesirable sensorial characteristics, in part due to the production of volatile phenols and acetate esters. The persistence of Dekkera spp. in industrial manufacturing environments can be attributed to its strong bioadhesive properties, allowing it to attach to various surfaces and form biofilms, which often contribute to recurrent contaminations.

A Q-Operator for Open Spin Chains II: Boundary Factorization.

One of the features of Baxter's Q-operators for many closed spin chain models is that all transfer matrices arise as products of two Q-operators with shifts in the spectral parameter. In the representation-theoretical approach to Q-operators, underlying this is a factorization formula for L-operators (solutions of the Yang-Baxter equation associated to particular infinite-dimensional representations). To extend such a formalism to open spin chains, one needs a factorization identity for solutions of the reflection equation (boundary Yang-Baxter equation) associated to these representations.

Assessment of fine-tuned large language models for real-world chemistry and material science applications.

The current generation of large language models (LLMs) has limited chemical knowledge. Recently, it has been shown that these LLMs can learn and predict chemical properties through fine-tuning. Using natural language to train machine learning models opens doors to a wider chemical audience, as field-specific featurization techniques can be omitted.

COVID-19 vaccine hesitancy and attitudes toward routine vaccinations among Venezuelan migrants in Trinidad and Tobago: implications for a National Immunization Policy.

Introduction: Vaccine hesitancy poses a threat to the prevention of COVID-19 and other vaccine-controlled diseases. In 2019, the Government of Trinidad and Tobago launched a policy outlining the scope of health services in the public sector available to registered Venezuelan migrants to include access to routine immunizations. Little is understood about immunization uptake among migrants, including the uptake of COVID-19 vaccinations in Trinidad and Tobago.

The coordination chemistry of -butylcalix[8]arene with transition and lanthanide metal ions.

A survey of the literature and the Cambridge Structural Database reveals thirty nine -butylcalix[8]arene-supported transition (3d, limited to V-Cu) and lanthanide metal complexes ranging in nuclearity from one to eighteen, twenty of which are homometallic and nineteen of which are heterometallic. We provide a review of the coordination chemistry of these complexes, including our own work in the area. We also provide our thoughts and perspectives on the common structural themes observed, identify gaps in knowledge and evaluate how that may inform and direct future synthetic efforts.

Deposition simulations of realistic dosages in patient-specific airways with two- and four-way coupling.

Inhalers spray over 100 million drug particles into the mouth, where a significant portion of the drug may deposit. Understanding how the complex interplay between particle and solid phases influence deposition is crucial for optimising treatments. Existing modelling studies neglect any effect of particle momentum on the fluid (one-way coupling), which may cause poor prediction of forces acting on particles.

Super-resolution ultrasound imaging of ischaemia flow: An in silico study.

Super-resolution ultrasound (SRU) is a new ultrasound imaging mode that promises to facilitate the detection of microvascular disease by providing new vascular bio-markers that are directly linked to microvascular pathophysiology, thereby augmenting current knowledge and potentially enabling new treatment. Such a capability can be developed through thorough understanding as articulated by means of mathematical models. In this study, a 2D numerical flow model is adopted for generating flow adaptation in response to ischaemia, in order to determine the ability of SRU to register the resulting flow perturbations.

Polymicrobial outbreak of Carbapenemase producing Enterobacterales managed using universal admission and discharge screening and water-safe built environment.

Background: Carbapenemase producing Enterobacterales (CPE) are antimicrobial resistant (AMR) bacteria which are increasing in incidence globally. Hospitals act as powerhouses for transmission of such bacteria with some regions experiencing prolonged outbreaks and high prevalence for several years. Current screening strategies are based on admission and risk-based screening only.

Risk contagion of COVID-19 to oil prices: A Markov switching GARCH and PCA approach.

The COVID-19 pandemic and its impact on crude oil prices created additional risks throughout the financial industry. To contribute to the ongoing debates, this paper empirically examined the risk contagion of COVID-19 to oil prices by incorporating a Markov-Switching GARCH (MS-GARCH) framework and the multivariate GARCH time series model, BEKK-GARCH model. The study examines data collected between 27 January 2020 and 31 December 2020.

Topological phase transition and surface states in a non-Abelian charged nodal line photonic crystal.

Topological charges of nodal lines in a multigap system are represented by non-Abelian numbers, and the Euler class, a topological invariant, can be used to explain their topological phase transitions, such as pair-annihilation of nodal lines. Up until now, no discussion of phase transitions of nodal lines in photonic crystals using the Euler class has been reported, despite the fact that the Euler class and topological phase transition have recently been addressed in metallic or acoustic crystals. Here, we show how the deformation of a photonic crystal causes topological phase transitions in the nodal lines, and the Euler class can be used to theoretically predict the nodal lines' stability based on the non-Abelian topological charge theory.

Exploring the 'EarSwitch' concept: a novel ear based control method for assistive technology.

Background: Loss of communication with loved ones and carers is one of the most isolating and debilitating effects of many neurological disorders. Assistive technology (AT) supports individuals with communication, but the acceptability of AT solutions is highly variable. In this paper a novel ear based control method of AT, the concept of 'EarSwitch', is presented.

Collaborative learning in older age and the role of familiarity: evidence from the map task.

As we age, learning new knowledge and skills becomes more difficult due to age-related changes to cognition. Learning collaboratively could counteract these changes, and perhaps more so when working with someone familiar. This study examined whether collaborative learning is affected by age and partner familiarity.
