Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

Advanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Holes Processing in Voronoi Diagram with Rectangular Sites for the Comparative Analysis of Slab Deformations

Информатика и автоматизация
In this article, a new Voronoi diagram algorithm with rectangular sites and holes is proposed. The algorithm is based on the existing Voronoi diagram algorithm with the L∞ distance metric by Papadopoulou E. and Lee D.-T.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells

Advanced Science, EarlyView.
BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

Animal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Cardiovascular Exercise Drives Neuroprotection in a Mouse Model of Spinocerebellar Ataxia 1 Via Rescue of Aberrant Splicing

Annals of Neurology, EarlyView.
Objective Spinocerebellar ataxia 1 (SCA1) is a fatal hereditary neurodegenerative disorder with no approved therapies, and gene‐targeting strategies have thus far failed in clinical trials. Exercise remains the only intervention shown to provide clinical benefit in patients with spinocerebellar ataxias (SCAs), yet the underlying mechanisms remain ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Solar photospheric spectrum microvariability

Astronomy & Astrophysics
Context. Finding low-mass planets around solar-type stars requires understanding the physical variability of the host star, which greatly exceeds the planet-induced radial-velocity modulation.

Angle bisectors of a triangle in $I_2$

Mathematical Communications, 2008
The concept of an angle bisector of the triangle will be introduced in an isotropic plane. Some statements about relationships between the introduced concepts and some other previously studied geometric concepts about triangles will be investigated in an isotropic plane.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
