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

open access: yesAdvanced 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 ...

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation

open access: yesAdvanced Science, EarlyView.
A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

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

open access: yesAdvanced 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.

Homogeneous Einstein metrics

open access: yes, 1995
We consider homogeneous Einstein metrics on symmetric spaces and we describe their geometry. For compact irreducible symmetric spaces with rank($M) \u3e 1$, not isometric to a Lie group, we classify all homogeneous Einstein metrics. Whenever there exists

Defect‐Functionalization‐Mediated Tunneling Drives Nonlinear Photoemission in Perovskites

open access: yesAdvanced Science, EarlyView.
This cover illustration depicts CsPbBr3 perovskite nanocrystals embedded with functionalized defect vacancies, where electrons migrate through defect‐mediated pathways and emit as lightning‐like beams. The imagery visualizes the core discovery of our work—defect‐functionalization‐mediated tunneling enabling nonlinear photoemission, where deep‐level ...

On Concircular Transformations in Finsler Spaces

open access: yesپژوهش‌های ریاضی, 2021
Randers metrics are the most important class of Finsler metrics which is defined by a Riemannian metric  and a 1-form  as    . In this paper, the concept of geodesic circle preserve transformations in  Finslerian space is studied and the weak Einstein ...

Conical Kähler–Einstein Metrics Revisited

open access: yesCommunications in Mathematical Physics, 2014
In this paper we introduce the "interpolation-degneration" strategy to study Kahler-Einstein metrics on a smooth Fano manifold with cone singularities along a smooth divisor that is proportional to the anti-canonical divisor. By "interpolation" we show the angles in $(0, 2π]$ that admit a conical Kahler-Einstein metric form an interval; and by ...

Cohomogeneity One Einstein Metrics on Vector Bundles [PDF]

open access: yes, 2019
This thesis studies the construction of noncompact Einstein manifolds of cohomogeneity one on some vector bundles. Cohomogeneity one vector bundle whose isotropy representation of the principal orbit G/K has two inequivalent irreducible summands has ...

Bismut Einstein metrics on compact complex manifolds

open access: yes, 2023
We observe that, for a Bismut Einstein metric, the (2,0)-part of Bismut Ricci form is an eigenvector of the Chern Laplacian. With the help of this observation, we prove that a Bismut Einstein metric with non-zero Einstein constant is K\"ahler Einstein ...
