Advanced Science, EarlyView.Mitochondria across the entire neuromuscular system have been comprehensively reconstructed at different developmental stages using 3D electron microscopy. Fundamental structural principles related to synaptic function are preserved across development, and these morphologies are adapted to ensure effective neural circuit function.

ON-RECURRENT LORENTZIAN -KENMOTSU MANIFOLDS
Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009 : In this paper, we study Lorentzian -Kenmotsu manifold and we shown that -recurrent Lorentzian -Kenmotsu manifold is an Einstein manifold and a pseudo-projective -recurrent Lorentzian -Kenmotsu manifold is an - Einstein manifold.

Regge's Einstein-Hilbert Functional on the Double Tetrahedron [PDF]
, 2010 The double tetrahedron is the triangulation of the three-sphere gotten by gluing together two congruent tetrahedra along their boundaries. As a piecewise flat manifold, its geometry is determined by its six edge lengths, giving a notion of a metric on ...

New supersymmetric AdS4 type II vacua
, 2009 Building on our recent results on dynamic SU(3)xSU(3) structures we present a set of sufficient conditions for supersymmetric AdS4xM6 backgrounds of type IIA/IIB supergravity.

Compact gradient Einstein-type manifolds with boundary and constant scalar curvature [PDF]
arXiv, 2022 Inspired by the study of $V$-static manifold about classification, in this article, we apply the recent results obtained by Freitas and Gomes (Compact gradient Einstein-type manifolds with boundary, 2022) to prove the rigidity results for compact gradient Einstein-type manifolds with nonempty boundary and constant scalar curvature under some suitable ...

Advanced Science, EarlyView.By studying the maturation mechanisms of vasopressin (AVP), this manuscript identifies FAM134B‐mediated ER‐phagy as a critical pathway for degrading both aggregated proAVP and the key ERAD component, HRD1. HRD1 induction mitigates proAVP aggregation and support AVP neuron function in the absence of autophagy.

Einstein Manifolds As Yang-Mills Instantons
, 2013 It is well-known that Einstein gravity can be formulated as a gauge theory of Lorentz group where spin connections play a role of gauge fields and Riemann curvature tensors correspond to their field strengths.

Some Types of Weakly Ricci Symmetric Riemannian Manifolds [PDF]
arXiv, 2021 In this paper we discuss when a quasi-conformally flat weakly Ricci symmetric manifold (of dimension greater than 3) becomes a manifold of hyper quasi-constant curvature, a quasi-Einstein manifold and a manifold of quasi-constant curvature. Also we discuss when a pseudo projectively flat weakly Ricci symmetric manifold (of dimension greater than 3 ...

Variable‐Range Hopping Conduction in Amorphous, Non‐Stoichiometric Gallium Oxide
Advanced Electronic Materials, EarlyView.The combination of experimental evidence, ab‐initio DOS calculations and quantitative modeling by kinetic Monte Carlo simulations reveals: Variable‐range hopping (VRH) is the dominant electron conduction mechanism in a‐GaOx (x = 0.8 to 1.0), even at room temperature, which leads to a new, fundamental understanding of a‐GaOx‐based electronic devices ...
