Bench‐to‐Bedside Translation of Self‐Healing Colloidal Hydrogels as Next Generation Design of Flowable Hemostatic Matrix: From Preclinical Evaluation to Human Clinical Trials

Advanced Science, EarlyView.
ABSTRACT Self‐healing materials represent a paradigm shift in designing functional biomedical devices for drug delivery, tissue regeneration, and 3D bioprinting. However, their clinical translation remains limited by challenges such as insufficient mechanical strength, potential cytotoxicity from chemical modifications, and complex activation ...

SMOOTH METRIC MEASURE SPACES AND QUASI-EINSTEIN METRICS [PDF]

International Journal of Mathematics, 2012
Smooth metric measure spaces have been studied from the two different perspectives of Bakry–Émery and Chang–Gursky–Yang, both of which are closely related to work of Perelman on the Ricci flow. These perspectives include a generalization of the Ricci curvature and the associated quasi-Einstein metrics, which include Einstein metrics, conformally ...

Nucleation Kinetics Reveals a Distinct Biological Function Space of Biomolecular Condensates

Advanced Science, EarlyView.
This study utilizes microfluidics to quantify the nucleation rates of dense liquid phases within dilute solutions and of the reverse process, in which dilute voids nucleate inside condensates. The interfacial tension is identified as the key determinant of both processes.

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

Advanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Isometry group of Sasaki–Einstein metric [PDF]

Comptes Rendus. Mathématique, 2013
In this short paper we prove a conjecture of Martelli–Sparks–Yau regarding the isometry group of a Sasaki–Einstein metric.

Thermally Modulated Specular Phonon Transport in a High‐Debye‐Temperature Diamond Nanobeam

Advanced Science, EarlyView.
Thermal transport in single‐crystal diamond nanobeams is measured from 140 to 300 K using electro‐thermal micro‐suspended structures. The thermal conductivity shows an increasing deviation from Boltzmann transport predictions assuming fully diffuse boundary scattering at lower temperatures.

Description of gravity in the model with independent nonsymmetric connection

EPJ Web of Conferences, 2017
A generalization of General Relativity is studied. The standard Einstein-Hilbert action is considered in the Palatini formalism, where the connection and the metric are independent variables, and the connection is not symmetric.

Einstein Metrics via Derdziński Duality

The Journal of Geometric Analysis
Abstract Drawing on results of Derdziński’s from the 1980s, we classify conformally Kähler, U(2)-invariant, Einstein metrics on the total space of $${{\mathcal {O}}}(-m)$$ O ( - m

Programmable Hydration Pathways Enable Reconfigurable Ionic Thermoelectrics for Energy Harvesting and Thermal‐Tactile Interaction

Advanced Science, EarlyView.
Programmable hydration pathways enable reconfigurable ionic thermoelectrics in polyquaternium hydrogels. By coupling microscopic solvation, mesoscale water channels, and macroscopic boundary control, hydration‐gated protonics decouples thermopower, response speed, and stability.

FIVE DIMENSIONAL BOOSTS AND ELECTROMAGNETIC FIELD IN KALUZA-KLEIN THEORY

Odessa Astronomical Publications, 2016
A stationary, spherically symmetric, 5D Kaluza-Klein theory exhibits 5D boosts. After reduction of 5D vacuum Einstein action of a diagonal 5D metric, we obtained Einstein equations with energy-momentum tensor of a massless scalar field.
