ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland
Advanced Science, EarlyView.In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

Advanced Science, EarlyView.A bio‑based thermoresponsive controlled‑release fertilizer (TRBF) is fabricated by introducing F127 into a castor‑oil‑derived polyurethane coating. Distinct from conventional bio‑based coated fertilizer (BCF), TRBF achieves temperature‑regulated nitrogen release via F127 reversible phase transition, suppressing nutrient leakage at low temperature and ...

ON THE LIFTS OF SEMI-RIEMANNIAN METRICS [PDF]
Journal of Sciences, Islamic Republic of Iran, 1994 In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a

Finsler–Randers–Sasaki gravity and cosmology
European Physical Journal C: Particles and FieldsWe present for the first time a Friedmann-like construction in the framework of an osculating Finsler–Randers–Sasaki (F–R–S) geometry. In particular, we consider a vector field in the metric on a Lorentz tangent bundle, and thus the curvatures of ...

Mechanism of Direct Acoustic Construction and Gradient Properties Tuning
Advanced Science, EarlyView.Directed acoustic construction enables omnidirectional gradient tuning of fingerprint‐inspired microstructures. By investigating the DAC mechanisms, diamond particles are found to enhance acoustic physical, mechanical, and chemical effects, promoting acoustic curing and broadening the range of gradient property tuning.

Advanced Science, EarlyView.A pork belly‐inspired all‐biomass composite film was constructed through layer‐by‐layer assembly of cellulose nanofibers (CNFs), gelatin, and graphitized carbon nanosheets (GCNs) via hydrogen bonding and π–π stacking interactions. The excellent mechanical properties, effective thermal management, and outstanding EMI shielding performance of the ...

On the CR structure of the tangent sphere bundle
Le Matematiche, 1995 We adopt the methods of pseudohermitian geometry (cf. [16]) to study the tangent sphere bundle U(M) over a Riemannian manifold M. If M is an elliptic space form of sectional curvature 1 then U(M) is shown to be globally pseudo-Einstein (in the sense of J.
