Odd Connections on Supermanifolds: Existence and relation with Affine Connections
, 2020 The notion of an odd quasi-connection on a supermanifold, which is loosely an affine connection that carries non-zero Grassmann parity, is examined. Their torsion and curvature are defined, however, in general, they are not tensors.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Political Connections and Social Networks in Targeted Transfer Programmes: Evidence from Rural Ethiopia [PDF]
In many developing countries, the beneficiaries of transfer programmes are determined by community-based processes, based on some general targeting rules related to needs. This opens the door for local social and political processes to impact on who gets

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows
Advanced Engineering Materials, EarlyView.A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Affine Connections in Quantum Gravity and New Scalar Fields
, 2019 International audienceIn this manuscript, we will discuss the construction of covariant derivative operator inquantum gravity. We will find it is more perceptive alternative to use affine connections more general than metric compatible connections in ...

Generalized integrability and the connections between Skyrme–Faddeev and Yang–Mills theories
Physics Letters B, 2002 Skyrme theory on S^2 (Faddeev coset proposal), is analyzed with a generalization of 0-curvature integrability, based on gauge techniques. New expressions valid for models in the sphere are given. The relation of the minimum energy configurations to gauge vacua is clarified.
