Soft Power in Hard Times: India’s Cautious Re-engagement with Taliban ruled Afghanistan [PDF]

Revista UNISCI
This article analyses India’s soft power strategy in Afghanistan across three phases: its consolidation (2001–2021), abrupt disruption following the Taliban’s return, and cautious recalibration thereafter. It contends that, despite the inherent limits of

Least-Squares Proper Generalised Decompositions for Weakly Coercive Elliptic Problems

, 2017
Proper generalized decompositions (PGDs) are a family of methods for efficiently solving high-dimensional PDEs, which seek to find a low-rank approximation to the solution of the PDE a priori. Convergence of PGD algorithms can only be proven for problems

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

Advanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

A multiferroic material [NH2-CH+-NH2]Co(HCOO)3 of metal-organic frameworks with weak ferromagnetism and dielectric relaxation

AIP Advances, 2017
In order to seek for the single-phase multiferroic metal-organic frameworks (MOFs) materials, we prepared a multiferroic material [NH2-CH+-NH2]Co(HCOO)3 (FMDCo) by solvothermal method.

The analysis of the remanence coercivity spectrum by continuous and alternating fields: relationship between coercivity and alternating fields stability spectra

, 1986
Comparison of results obtained from a variety of natural rock samples using both continuous and alternating field ( c .f and a.f) techniques demonstrates the complementary nature and potential of the two techniques . The re mane nee coercivity spectrum is analyzed by obtaining families of hysteresis curves inc .f of up to 1200 mT. The extraction of the

Approximate solution for an inverse problem of multidimensional elliptic equation with multipoint nonlocal and Neumann boundary conditions

Electronic Journal of Differential Equations, 2017
In this work, we consider an inverse elliptic problem with Bitsadze-Samarskii type multipoint nonlocal and Neumann boundary conditions. We construct the first and second order of accuracy difference schemes (ADSs) for problem considered.
