Platform capitalisms and platform cultures.

This article argues for a pluralization of the "platform capitalism" framework, suggesting we should think instead in terms of "platform capitalisms." This pluralization opens the way to a better account of how platforms work in different geocultural contexts, with our focus being on China, India and Japan. The article first outlines several roles the state has taken on in mediating platform capitalisms.

Heat and Drought Events Alter Biogenic Capacity to Balance CO Budget in South-Western Europe.

Heat and drought events are increasing in frequency and intensity, posing significant risks to natural and agricultural ecosystems with uncertain effects on the net ecosystem CO exchange (NEE). The current Vegetation Photosynthesis and Respiration Model (VPRM) was adjusted to include soil moisture impacts on the gross ecosystem exchange (GEE) and respiration ( ) fluxes to assess the temporal variability of NEE over south-western Europe for 2001-2022. Warming temperatures lengthen growing seasons, causing an increase in GEE, which is mostly compensated by a similar increment in .

Long-term Complications From Peripheral Nerve Blocks After Pediatric Orthopaedic Lower Extremity Procedures: A Systematic Review.

Background: Peripheral nerve blocks (PNBs) are frequently utilized as a regional anesthetic in pediatric orthopaedic surgery for postoperative pain control and reduced time to discharge; however, short- and long-term complications after these procedures are variably reported.

Purpose: To identify the frequency of long-term complications in pediatric patients who received regional anesthesia for a lower extremity orthopaedic procedure.

Study Design: Systematic review; Level of evidence, 4.

Assessment of modeled serum per- and polyfluoroalkyl substances concentrations from exposure estimates for pregnant women in the general population in comparison to previously measured serum concentrations.

When drinking water is uncontaminated, exposure to PFAS is thought to occur primarily via ingestion of food and indoor dust. To understand the background exposure during prenatal periods, this study examined whether published estimates of PFAS exposure rates from dietary and dust ingestion provide reasonable predictions of PFAS serum concentrations among pregnant women in the general population. This study estimated serum concentrations of four PFAS during pregnancy based on published PFAS intake rates for food and indoor dust reported in the peer-reviewed literature, a pharmacokinetic model using two different sets of parameters, and Monte Carlo simulation to account for variability/uncertainty.

Comparison of neuraminidase inhibiting antibody responses elicited by egg- and cell-derived influenza vaccines.

Unlabelled: Neuraminidase (NA)-specific antibodies contribute to immunity against influenza. While studies have demonstrated increased NA inhibiting (NAI) antibody titers after vaccination with egg-derived inactivated influenza vaccines (eIIV), the response to cell culture-derived (c) IIV has not been reported.

Methods: An immunogenicity sub-study was performed within a clinical trial comparing the effectiveness of egg, cell, and recombinant hemagglutinin (HA)-derived influenza vaccines during the 2018-2019 and 2019-2020 influenza seasons.

A Splice Site Variant in SENP7 Results in a Severe Form of Arthrogryposis.

Arthrogryposis multiplex congenita (AMC) is a heterogeneous disorder associated with 1/3000 to 1/5000 live births. We report a consanguineous family with multiple affected members with AMC and identified a recessive mutation in the highly conserved splice donor site, resulting in the mis-splicing of the affected exons. SENP7 is a deSUMOylase that is critical for sarcomere assembly and skeletal muscle contraction by regulating the transcriptional program in the skeletal muscle.

Use of Remote Regulatory Assessment (RRA) for Site Evaluations during the COVID-19 Pandemic: The USFDA's Office of Study Integrity and Surveillance (OSIS) Perspective.

Travel restrictions during the novel coronavirus, SARS-CoV-2 (COVID-19) public health emergency affected the U.S. Food and Drug Administration's (FDA) ability to conduct on-site bioavailability/bioequivalence (BA/BE) and Good Laboratory Practice (GLP) nonclinical inspections.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Controlling the Spatiotemporal Self-Organization of Stimuli-Responsive Nanocrystals under Out-of-Equilibrium Conditions.

Self-organization under out-of-equilibrium conditions is ubiquitous in natural systems for the generation of hierarchical solid-state patterns of complex structures with intricate properties. Efforts in applying this strategy to synthetic materials that mimic biological function have resulted in remarkable demonstrations of programmable self-healing and adaptive materials. However, the extension of these efforts to multifunctional stimuli-responsive solid-state materials across defined spatial distributions remains an unrealized technological opportunity.

Therapeutic potential of mesenchymal stem cells on cholesterol homeostasis-associated genes in AD-like rats.

Cholesterol is vital for nerve processes. Changes in cholesterol homeostasis lead to neurodegeneration and Alzheimer's disease (AD). In recent years, extensive research has confirmed the influential role of adipose tissue mesenchymal stem cells (MSCs) in managing AD.

Addressing STIs through managed care: opportunities in Medicaid and beyond.

The US is facing a growing epidemic of sexually transmitted infections (STIs), with over 2.5 million cases of chlamydia, gonorrhea, and syphilis reported in 2021 and again in 2022. This public health crisis disproportionately affects youth and racial and ethnic minority communities, exacerbating barriers to accessing sexual health services.

Perspectives of Older Patients on Speaking With an Anesthesia Provider Before the Day of Surgery: A Cross-Sectional Study.

Background: Evaluations performed before the day of surgery at perioperative clinics have been shown to reduce patient mortality and hospital lengths of stay. These clinics are becoming increasingly adopted worldwide. As the number of older patients undergoing surgery continues to increase, understanding the perspectives of this patient population regarding the preoperative evaluation process is essential to tailor care to their needs and preferences.

Plant and soil microbial composition legacies following indaziflam herbicide treatment.

Land stewards in dryland ecosystems across the western U.S. face challenges to manage the exotic grass (cheatgrass), which is a poor forage, is difficult to remove, and increases risk of catastrophic fire.

The risk status, signatures of adaptation, and environmental suitability of village-based indigenous chickens from certain regions of Limpopo and KwaZulu-Natal provinces of South Africa.

Indigenous chickens are an important Farm Animal Genetic Resource (FAnGR) in South Africa as they alleviate poverty and are a source of protein. Climate change and market demand for high-performing exotic breeds threaten and undermine locally adapted village chickens. The current study explored the risk status and signatures of adaptation of village-based indigenous chickens from two provinces and mapped their environmental suitability across the country.

Considerations for Social Networks and Health Data Sharing: An Overview.

The use of network analysis as a tool has increased exponentially as more clinical researchers see the benefits of network data for modeling of infectious disease transmission or translational activities in a variety of areas, including patient-caregiving teams, provider networks, patient-support networks, and adoption of health behaviors or treatments, to name a few. Yet, relational data such as network data carry a higher risk of deductive disclosure. Cases of reidentification have occurred and this is expected to become more common as computational ability increases.

Factorial Design of Experiment Method to Characterize Bioprinting Process Parameters to Obtain the Targeted Scaffold Porosity.

Due to its inbuilt ability to release biocompatible materials encapsulating living cells in a predefined location, 3D bioprinting is a promising technique for regenerating patient-specific tissues and organs. Among various 3D bioprinting techniques, extrusion-based 3D bioprinting ensures a higher percentage of cell release, ensuring suitable external and internal scaffold architectures. Scaffold architecture is mainly defined by filament geometry and width.

Developing and Comparing Four Families of Bayesian Network Autocorrelation Models for Binary Outcomes: Estimating Peer Effects Involving Adoption of Medical Technologies.

Despite the extensive use of network autocorrelation models in social network analysis, network autocorrelation models for binary dependent variables have received surprisingly scant attention. In this paper, we develop four network autocorrelation models for a binary random variable defined by whether the peer effect (also termed social influence or contagion) acts on latent continuous outcomes leading to an indirect effect under a normal or a logistic distribution or on the probability of the observed outcome itself under a probit or a logit link function defining a direct effect to account for interdependence between outcomes. For all models, we use a Bayesian approach for model estimation under a uniform prior on a transformed peer effect parameter ( ) designed to enhance model computation and compare results to those under the uniform prior for .

Phage-Encoded Virulence Factor, Gp05, Alters Membrane Phospholipids and Reduces Antimicrobial Susceptibility in Methicillin-Resistant Staphylococcus aureus.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a leading pathogen causing severe endovascular infections. The prophage-encoded protein Gp05 has been identified as a critical virulence factor that contributes to MRSA persistence during vancomycin (VAN) treatment in an experimental endocarditis model. However, the underlining mechanisms driving this persistence phenotype remain poorly understood.

Community Synchrony in Seed Production is Associated With Trait Similarity and Climate Across North America.

Mast seeding, the synchronous and highly variable production of seed crops by perennial plants, is a population-level phenomenon and has cascading effects in ecosystems. Mast seeding studies are typically conducted at the population/species level. Much less is known about synchrony in mast seeding between species because the necessary long-term data are rarely available.

Incidental affect influences choice preference among competing alternatives in a modified Affect Misattribution Procedure.

Affective feelings exert a powerful influence on decision making, even when the source of those feelings is incidental, i.e., unrelated to the decision at hand.

Territory Sizes and Patterns of Habitat Use by Forest Birds Over Five Decades: Ideal Free or Ideal Despotic?

Relations among territoriality, abundance and habitat suitability are fundamental to the ecology of many animal populations. Theory suggests two classes of possible responses to increasing abundance in territorial species: (1) the ideal free distribution (IFD), which predicts smaller territory sizes and decreased fitness as individuals adaptively pack into suitable habitats, and (2) the ideal despotic distribution (IDD), which predicts stable territory sizes and fitness in preferred habitats for dominant individuals and increased use of marginal habitats, reduced fitness and changes in territory sizes for subordinate individuals. We analysed the territory sizes and locations of seven migratory songbird species occupying a 10-ha plot in the Hubbard Brook Experimental Forest, New Hampshire, USA over a 52-year period.

Estimation of Ligand Binding Free Energy Using Multi-eGO.

The computational study of ligand binding to a target protein provides mechanistic insight into the molecular determinants of this process and can improve the success rate of drug design. All-atom molecular dynamics (MD) simulations can be used to evaluate the binding free energy, typically by thermodynamic integration, and to probe binding mechanisms, including the description of protein conformational dynamics. The advantages of MD come at a high computational cost, which limits its use.
