The supercurrent and Einstein equations in the superconformal formulation

Journal of High Energy Physics, 2017
We give a new expression for the supercurrent and its conservation in curved N $$ \mathcal{N} $$ =1, D = 4 superspace using the superconformal approach. The first component of the superfield, whose lowest component is the vector auxiliary field gives the

2-conformal and conformal vector fields on Riemannian manifolds

Filomat
In this paper, we study 2-conformal vector fields on Riemannian manifolds. Some relations between 2-conformal vector fields, conformal vector fields, Killing and 2-Killing vector fields have been obtained. Also, relation between monotone vector fields and 2-conformal vector fields is investigated.

Essential points of conformal vector fields

Journal of Geometry and Physics, 2011
For a conformal vector field $ξ$ on a Riemannian manifold, we say that a point is essential if there is no local metric in the conformal class for which $ξ$ is Killing. We show that the only essential points are isolated zeros of $ξ$. As an application, we show that every connected component of the zero set of $ξ$ is totally umbilical.

Locally Conformal Almost Cosymplectic Manifolds Endowed with a Skew-Symmetric Killing Vector Field [PDF]

論文(Article)We study a locally conformal almost cosymplectic manifold M which carries a horizontal skew-symmetric Killing vector field X. Such X denes a relative conformal cosymplectic transformation of the conformal cosymplectic 2-form Ω of M and the ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Conformal Solutions of Static Plane Symmetric Cosmological Models in Cases of a Perfect Fluid and a Cosmic String Cloud

Axioms
In this work, we obtained exact solutions of Einstein’s field equations for plane symmetric cosmological models by assuming that they admit conformal motion.

Spatially Configurable Conformal Sensor Integration on an Ultra‐Fine Metallic Needle for Minimally Invasive Deep‐Tissue Oxygen Monitoring

Advanced Materials Technologies, EarlyView.
A multi‐point oxygen‐sensing ultra‐fine needle (MO‐UFN) is developed by conformally integrating a lithographically patterned flexible electrochemical sensor array onto a clinical acupuncture needle. The platform preserves an approximately 0.3 mm diameter while enabling spatially resolved oxygen profiling along the insertion pathway.

External leg amputation in conformal-invariant three-point function

, 2011
Amputation of external legs is carried out explicitly for the conformal-invariant three-point function involving two spinors and one vector field. Our results are consistent with the general result that amputating an external leg in a conformal-invariant

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB
