Optical cavity-mediated exciton dynamics in photosynthetic light harvesting 2 complexes

Strong light-matter interaction leads to the formation of hybrid polariton states and alters the photophysical dynamics of organic materials and biological systems without modifying their chemical structure. Here, we experimentally investigated a well-known photosynthetic protein, light harvesting 2 complexes (LH2) from purple bacteria under strong coupling with the light mode of a Fabry-Perot opt

Effects of parasitic freshwater mussels on their host fishes : a review

Freshwater mussels in the order Unionida are highly adapted to parasitize fish for the primary purpose of dispersal. The parasitic larval stage affixes itself to the gills or fins of the host where it becomes encysted in the tissue, eventually excysting to develop into a free-living adult. Research on the parasitic interactions between unionids and their host fishes has garnered attention recently

Associations of Negative Life Events with Quality of Life : a 10-Year Cohort of Chinese Wenchuan Earthquake Adolescents Survivors

Previous work regarding the relationship between negative life events (NLEs) and survivors’ quality of life (QoL) post-disaster has commonly employed a variable-centered approach. Little is known about the roles of individual variance in time-varying changes of NLEs in future QoL. Moreover, whether sex modifies the impacts of NLEs trajectories on QoL is still understudied. We addressed these issue

On an Eigenvalue Property of Summation-By-Parts Operators

Summation-By-Parts (SBP) methods provide a systematic way of constructing provably stable numerical schemes. However, many proofs of convergence and accuracy rely on the assumption that the SBP operator possesses a particular eigenvalue property. In this note, three results pertaining to this property are proven. Firstly, the eigenvalue property does not hold for all nullspace consistent SBP opera

Prevalence of skin sensitization and dermatitis among epoxy-exposed workers in the wind turbine industry

Background: A high prevalence of skin sensitization and dermatitis has been reported among workers exposed to epoxy components. Objectives: To estimate the risk of skin sensitization and dermatitis among workers exposed to epoxy components during production of wind turbine blades while using comprehensive safety measures. Methods: A cross-sectional study of 180 highly epoxy-exposed production work

Recurrence pattern in localized RCC : results from a European multicenter database (RECUR)

Introduction: The impact of open versus minimally invasive surgery on recurrence pattern in the management of localized renal cell carcinoma (RCC) remains uncertain. We thus aimed to determine the impact of surgical approach on survival and recurrence pattern. Material and methods: This is a multi-institutional, matched cohort study on patients with pT1-3aN0M0 RCC from the RECUR database. After pr

A camera trap-based assessment of climate-driven phenotypic plasticity of seasonal moulting in an endangered carnivore

For many species, the ability to rapidly adapt to changes in seasonality is essential for long-term survival. In the Arctic, seasonal moulting is a key life-history event that provides year-round camouflage and thermal protection. However, increased climatic variability of seasonal events can lead to phenological mismatch. In this study, we investigated whether winter-white (white morph) and winte

Traveling waves for a quasilinear wave equation

We consider a 2+1 dimensional wave equation appearing in the context of polarized waves for the nonlinear Maxwell equations. The equation is quasilinear in the time derivatives and involves two material functions V and Γ. We prove the existence of traveling waves which are periodic in the direction of propagation and localized in the direction orthogonal to the propagation direction. Depending on

On the Oxidative Valorization of Lignin to High-Value Chemicals : A Critical Review of Opportunities and Challenges

The efficient valorization of lignin is crucial if we are to replace current petroleum-based feedstock and establish more sustainable and competitive lignocellulosic biorefineries. Pulp and paper mills and second-generation biorefineries produce large quantities of low-value technical lignin as a by-product, which is often combusted on-site for energy recovery. This Review focuses on the conversio

Characterization of laser wakefield acceleration efficiency with octave spanning near-IR spectrum measurements

We report on experimental measurements of energy transfer efficiencies in a GeV-class laser wakefield accelerator. Both the transfer of energy from the laser to the plasma wakefield and from the plasma to the accelerated electron beam was diagnosed by simultaneous measurement of the deceleration of laser photons and the acceleration of electrons as a function of plasma length. The extraction effic

The Harald Breivik lecture 2022. Pathophysiology in persistent severe pain after groin hernia repair

The transition from a healthy to a persistent severe pain state following otherwise successful elective surgery is a feared complication. Groin hernia repair, previously considered minor surgery, is a standard surgical procedure annually performed on 2,000 individuals per one million residents. A trajectory into persistent severe pain is, unfortunately, seen in 2-4%, severely impeding physical and

New development : Marketization versus politicization in a perpetual strive for public audit independence

This article reports on an investigation of audit independence in the context of local public audit in Sweden. The article focuses on the influence of two different sets of interests. The results show that there is a risk that the way the results of the audit process are communicated and disseminated in an organization is influenced by political, as well as market, interests. The article reveals t

Risk assessment for comprehensive meteorological disaster of winter wheat based on multisource gridded data : A case study in the upper Huaihe River basin, China

Crop production security is an essential guarantee for the prosperity of country and the well-being of people. In the context of frequent occurrence of extreme weather events, how to comprehensively evaluate the risk of multiple hazards and quantitatively describe spatial differences will be one of the significant topics in agricultural disaster mitigation. In this study, based on the gridded mete

Transversal functional connectivity and scene-specific processing in the human entorhinal-hippocampal circuitry

Scene and object information reach the entorhinal-hippocampal circuitry in partly segregated cortical processing streams. Converging evidence suggests that such information-specific streams organize the cortical – entorhinal interaction and the circuitry’s inner communication along the transversal axis of hippocampal subiculum and CA1. Here, we leveraged ultra-high field functional imaging and adv

Progression models for repeated measures : Estimating novel treatment effects in progressive diseases

Mixed models for repeated measures (MMRMs) are ubiquitous when analyzing outcomes of clinical trials. However, the linearity of the fixed-effect structure in these models largely restrict their use to estimating treatment effects that are defined as linear combinations of effects on the outcome scale. In some situations, alternative quantifications of treatment effects may be more appropriate. In

Targeted proteomics identifies potential biomarkers of dysglycaemia, beta cell function and insulin sensitivity in Black African men and women

Aims/hypothesis: Using a targeted proteomics approach, we aimed to identify and validate circulating proteins associated with impaired glucose metabolism (IGM) and type 2 diabetes in a Black South African cohort. In addition, we assessed sex-specific associations between the validated proteins and pathophysiological pathways of type 2 diabetes. Methods: This cross-sectional study included Black So

The coexistence of the streaming instability and the vertical shear instability in protoplanetary disks : Planetesimal formation thresholds explored in two-dimensional global models

The streaming instability is a promising mechanism to induce the formation of planetesimals. Nonetheless, this process has been found in previous studies to require either a dust-to-gas surface density ratio or a dust size that is enhanced compared to observed values. Employing two-dimensional global simulations of protoplanetary disks, we show that the vertical shear instability and the streaming

Background: Contemporary data on stroke epidemiology and the availability of national stroke clinical registries are important for providing evidence to improve practice and support policy decisions. Aims: To update the most current incidence, case-fatality, and mortality rates on stroke and identify national stroke clinical registries worldwide. Methods: We searched multiple databases (based on o

Genomic trajectories of a near-extinction event in the Chatham Island black robin

Background: Understanding the micro-­evolutionary response of populations to demographic declines is a major goal in evolutionary and conservation biology. In small populations, genetic drift can lead to an accumulation of deleterious mutations, which will increase the risk of extinction. However, demographic recovery can still occur after extreme declines, suggesting that natural selection may pu
