Constraints from primordial black hole formation at the end of inflation

, 2010
Primordial black hole (PBH) abundance limits constrain the primordial power spectrum, and hence models of inflation, on scales far smaller than those probed by cosmological observations.

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

Mechanical, Thermal, and Microstructural Evaluation of Bio‐Based Polyurethane Composites Reinforced With Woven Jute and Flax

Polymer Composites, EarlyView.
Graphical overview of the manufacturing and characterization of bio‐based polyurethane composites reinforced with woven jute and flax fibers produced by the VARTM process. Mechanical, thermal, and microstructural analyses reveal differences in stiffness, thermal stability, and interfacial behavior between the natural fiber composites.

Interplay of Ser273 Phosphorylation and K268 and K293 Acetylation in PPARγ: Implications for PPARγ Activation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) play a critical role in regulating the transcriptional activity of PPARγ, a nuclear receptor central to glucose and lipid homeostasis. Among these, lysine acetylation at K268 and K293 and phosphorylation at S273 are particularly relevant to insulin sensitivity.

Elucidation of Degradation Mechanism, Kinetic Triplets and Product Analysis of Nafion N115 Membrane: An Experimental and Theoretical Study

Safety Science and Technology, EarlyView.
Thermal degradation mechanism and kinetic triplets of Nafion N115 were elucidated via TGA, kinetic compensation analysis, Sestak–Berggren reconstruction, quantum calculations, and GC–MS. A diffusion‐controlled model governs active pyrolysis, although persistent perfluorinated products were identified, highlighting environmental implications and ...

High throughput sequencing reveals alterations in the recombination signatures with diminishing Spo11 activity.

PLoS Genetics, 2013
Spo11 is the topoisomerase-like enzyme responsible for the induction of the meiosis-specific double strand breaks (DSBs), which initiates the recombination events responsible for proper chromosome segregation.

Productivity and Human Disturbance Shape Contrasting Distribution Patterns of Core and Occasional Bird Species in a Subtropical Forest Reserve in Southern China

Integrative Zoology, EarlyView.
Bird diversity hot spots in a recovering subtropical forest do not align with protected area zoning, instead occurring in experimental zones with low‐intensity human activity. This mismatch is driven by contrasting responses: Abundant core species are supported by productivity, while many species of low frequency are attracted to the habitat ...

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.
