Closed Form Expressions of Self and Mutual Inductance of Disk Coils and the Optimal Value of Self-Inductance

open access: yesZhongguo dianli, 2019
The disk coils are the core element of energy coupling of the wireless power transmission system blooming in recent years. By introducing generalized hypergeometric functions pFq, the integral expression of self-inductance of disk coils is transformed ...

Human‐Scale Rotating Magnetic Field Delivery With Permanent Magnets Under Anatomic and Robotic Constraints

open access: yesAdvanced Robotics Research, EarlyView.
Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

A non-planar two-loop three-point function beyond multiple polylogarithms

open access: yesJournal of High Energy Physics, 2017
We consider the analytic calculation of a two-loop non-planar three-point function which contributes to the two-loop amplitudes for t t ¯ $$ t\overline{t} $$ production and γγ production in gluon fusion through a massive top-quark loop.

Three improvements in reduction and computation of elliptic integrals

open access: yes, 2002
Three improvements in reduction and computation of elliptic integrals are made. 1. Reduction formulas, used to express many elliptic integrals in terms of a few standard integrals, are simplified by modifying the definition of intermediate "basic ...

Wireless Precise Manipulation of Tumor Spheroids Using a Millirobot Controlled by Permanent Magnetic Traps

open access: yesAdvanced Robotics Research, EarlyView.
A magnetic donut‐like millirobot is developed for label‐free pick‐and‐place of a tumor spheroid wirelessly controlled by a magnetic trap. Spheroids are important 3D multicellular culture systems that recapitulate key structural and functional features of native tissues.

Force–Displacement Characterization of PNIPAM Microactuators

open access: yesAdvanced Robotics Research, EarlyView.
A method to experimentally establish a force–displacement diagram of poly(N‐isopropyl acrylamide) (PNIPAM) microactuators, printed by 2PP, is presented herein. PNIPAM is a hydrogel whose volume and stiffness change with temperature due to the absorption or release of water.

Analysis of some localized boundary-domain integral equations [PDF]

open access: yes, 2009
Some direct segregated localized boundary-domain integral equation (LBDIE) systems associated with the Dirichlet and Neumann boundary value problems (BVP) for a scalar "Laplace" PDE with variable coefficient are formulated and analysed. The parametrix is

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

A closed form evaluation of the elliptic integral

open access: yes, 1971
The complete elliptic integral of the first kind K ( k ) K(k) is evaluated in terms of gamma functions for the moduli k = √ 2 − 1 k = \surd 2 - 1 ...

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...
