Evidence for bottom-up effects of moth abundance on forest birds in the north-boreal zone alone.

Insect declines are raising alarms regarding cascading effects on ecosystems, especially as many insectivorous bird populations are also declining. Here, we leveraged long-term monitoring datasets across Finland to investigate trophic dynamics between functional groups of moths and birds in forested habitats. We reveal a positive association between the biomass of adult- or egg-overwintering moths and the biomasses of resident and long-distance migrant birds reliant on caterpillars as breeding-season food in the north-boreal zone.

Separating dementia with Lewy bodies from Alzheimer's disease dementia using a volumetric MRI classifier.

Objectives: Distinguishing dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) dementia, particularly in patients with DLB and concomitant AD pathology (DLB/AD+), can be challenging and there is no specific MRI signature for DLB. The aim of this study is to examine the additional value of MRI-based brain volumetry in separating patients with DLB (AD+/-) from patients with AD and controls.

Methods: We included 1518 participants from four cohorts (ADC, ADNI, PDBP and PredictND); 147 were patients with DLB (n = 76, DLB/AD+; n = 71, DLB/AD-), 668 patients with AD dementia, and 703 controls.

Detection of Porcine Norovirus GII.18 Strains in Pigs Using Broadly Reactive RT-qPCR Assay for Genogroup II Noroviruses.

Noroviruses, belonging to the family Caliciviridae, are classified into at least ten genogroups (G) based on their major capsid protein (VP1). The common genogroup to be identified in both humans and pigs is GII, although porcine noroviruses (PoNoVs) belong to genotypes of their own (GII.11, GII.

Inheritance of Material Wealth in a Natural Population.

Evolutionary adaptation occurs when individuals vary in access to fitness-relevant resources and these differences in 'material wealth' are heritable. It is typically assumed that the inheritance of material wealth reflects heritable variation in the phenotypic abilities needed to acquire material wealth. We scrutinise this assumption by investigating additional mechanisms underlying the inheritance of material wealth in collared flycatchers.

Fates of nutrient elements and heavy metals during thermal conversion of cattle slurry-derived anaerobic digestates.

Thermal processes are emerging as promising solutions to recovering phosphorus and other nutrient elements from anaerobic digestates. The feasibility of nutrient element recovery depends largely on the fates of nutrient elements and heavy metals during thermal processing. This study assesses the partitioning of macronutrients (N, P, K, Na, Ca and Mg) and heavy metals (Zn, Cu, and Mn) between condensed and gaseous phases during thermal conversion of cattle slurry digestates in gas atmospheres of pyrolysis, combustion, and gasification processes.

Integrative Approaches to Study Virus Structures.

A virus particle must work as a strongroom to protect its genome, but at the same time it must undergo dramatic conformational changes to infect the cell in order to replicate and assemble progeny. Thus, viruses are miniaturized wonders whose structural complexity requires investigation by a combination of different techniques that can tackle both static and dynamic processes. In this chapter, we will illustrate how major structural techniques such as X-ray crystallography and electron microscopy can be combined with other techniques to determine the structure of complex viruses.

Strength and Poisson's ratio of fused filament fabrication parts made from carbon filler enhanced PEEK compounds at elevated temperatures.

Engineering plastics are finding widespread applications across a broad temperature spectrum, with additive manufacturing (AM) having now become commonplace for producing aerospace-grade components from polymers. However, there is limited data available on the behavior of plastic AM parts exposed to elevated temperatures. This study focuses on investigating the tensile strength, tensile modulus and Poisson's ratio of parts manufactured using fused filament fabrication (FFF) and polyetheretherketone (PEEK) plastics doped with two additives: short carbon fibers (SCFs) and multi-wall carbon nanotubes (MWCNTs).

Immunogenicity and safety of the 15-valent pneumococcal conjugate vaccine, a systematic review and meta-analysis.

Pneumococcal infections are a serious health issue associated with increased morbidity and mortality. This systematic review evaluated the efficacy, effectiveness, immunogenicity, and safety of the pneumococcal conjugate vaccine (PCV)15 compared to other pneumococcal vaccines or no vaccination in children and adults. We identified 20 randomized controlled trials (RCTs).

Ultrafast Floquet engineering of Fermi-polaron resonances in charge-tunable monolayer WSe devices.

Fermi polarons are emerging quasiparticles when a bosonic impurity immersed in a fermionic bath. Depending on the boson-fermion interaction strength, the Fermi-polaron resonances exhibit either attractive or repulsive interactions, which impose further experimental challenges on understanding the subtle light-driven dynamics. Here, we report the light-driven dynamics of attractive and repulsive Fermi polarons in monolayer WSe devices.

Anti-CTLA4 treatment reduces lymphedema risk potentially through a systemic expansion of the FOXP3 T population.

Secondary lymphedema is a common sequel of oncologic surgery and presents a global health burden still lacking pharmacological treatment. The infiltration of the lymphedematous extremities with CD4T cells influences lymphedema onset and emerges as a promising therapy target. Here, we show that the modulation of CD4FOXP3CD25regulatory T (T) cells upon anti-CTLA4 treatment protects against lymphedema development in patients with melanoma and in a mouse lymphedema model.

Collaborative machine learning-guided overall survival prediction of oral squamous cell carcinoma.

Background: There is a lack of prognosticators of overall survival (OS) for Oral Squamous Cell Carcinoma (OSCC).

Objectives: We examined collaborative machine learning (cML) in estimating the OS of OSCC patients. The prognostic significance of the clinicopathological parameters was examined.

Temporal Changes in the Role of Species Sorting and Evolution Determine Community Dynamics.

Evolutionary change within community members and shifts in species composition via species sorting contribute to community and trait dynamics. However, we do not understand when and how both processes contribute to community dynamics. Here, we estimated the contributions of species sorting and evolution over time (60 days) in bacterial communities of 24 species under selection by a ciliate predator.

Global Biases in Ecology and Conservation Research: Insight From Pollinator Studies.

In the fields of ecology and conservation, taxonomic and geographic biases may compromise scientific progress. Using pollinator research as a case study, we evaluate four drivers of these biases and propose solutions to address (i) untested generalisations from highly studied taxa, (ii) information accessibility, (iii) scattered environmental regulations and (iv) restricted infrastructure and funding resources. Expanding the taxonomic, functional and geographic breadth of research and legislation, and involving scientists in policymaking, can generate greater equity, accessibility and impact of future science.

Real-Time Tractography-Assisted Neuronavigation for Transcranial Magnetic Stimulation.

State-of-the-art navigated transcranial magnetic stimulation (nTMS) systems can display the TMS coil position relative to the structural magnetic resonance image (MRI) of the subject's brain and calculate the induced electric field. However, the local effect of TMS propagates via the white-matter network to different areas of the brain, and currently there is no commercial or research neuronavigation system that can highlight in real time the brain's structural connections during TMS. This lack of real-time visualization may overlook critical inter-individual differences in brain connectivity and does not provide the opportunity to target brain networks.

Dual-stage optimizer for systematic overestimation adjustment applied to multi-objective genetic algorithms for biomarker selection.

The selection of biomarker panels in omics data, challenged by numerous molecular features and limited samples, often requires the use of machine learning methods paired with wrapper feature selection techniques, like genetic algorithms. They test various feature sets-potential biomarker solutions-to fine-tune a machine learning model's performance for supervised tasks, such as classifying cancer subtypes. This optimization process is undertaken using validation sets to evaluate and identify the most effective feature combinations.

Aalto Gear Fault datasets for deep-learning based diagnosis.

Accurate system health state prediction through deep learning requires extensive and varied data. However, real-world data scarcity poses a challenge for developing robust fault diagnosis models. This study introduces two extensive datasets, Aalto Shim Dataset and Aalto Gear Fault Dataset, collected under controlled laboratory conditions, aimed at advancing deep learning-based fault diagnosis.

Collected data on bending, vibration, and push-out tests of shallow steel-timber composite beams-Nordic system.

In a slim-floor structural system, beams and slabs are placed at the same level, reducing the overall floor height and material usage in vertical structures, thereby improving economic efficiency. The use of slim-floor structures is common practice in Finnish construction where these structures are typically constructed using hollow-concrete slabs and welded steel box beams. However, in Finland, only a few buildings utilise cross-laminated timber (CLT) slabs in slim-floor structures, and none have incorporated the composite action between CLT and steel beams.

Plant food consumption and emotional well-being: the Helsinki Health Study among 19-39-year-old employees.

This study among Finnish municipal employees examined associations of the consumption of a range of different plant foods with emotional well-being (EWB).

Data And Methods: We used survey data from the Helsinki Health Study conducted in 2017 among 19-39-year-old employees of the City of Helsinki, Finland (N = 5898, response rate 51.

The incidence of venous thromboembolism is low when risk stratification-based thromboprophylaxis is used after fast-track hip and knee arthroplasty.

Background: The optimal length of thromboprophylaxis after total hip or knee arthroplasty (THA and TKA) is unknown. Fast-track protocols have improved patient care and led to shorter immobilization and length of stay (LOS) after THA and TKA, thereby diminishing venous thromboembolism (VTE) risk. Here, we investigated risk stratification-based thromboprophylaxis after fast-track THA and TKA.
