Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots
Advanced Materials, EarlyView.A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Finite-Time Consensus of Finite Field Networks With Stochastic Time Delays
IEEE Transactions on Circuits and Systems II: Express Briefs, 2020This brief aims to solve the finite-time consensus problem of finite field networks (FFNs) with stochastic time delays. An algebraic state space representation (ASSR) approach is introduced for the investigation of this problem. Firstly, the concept of finite-time consensus with probability one is defined for FFNs with two kinds of stochastic time ...

Thermodynamics in finite time. II. Potentials for finite-time processes
Physical Review A, 1977Within the context of conventional time-independent thermodynamics, an algorithm is developed to construct potentials $\mathcal{P}$ that define the extremal values of work for processes with arbitrary constraints. An existence theorem is proved that demonstrates that such potentials $\mathcal{P}$ can be given for any quasistatic process.

If a message can have n different values and all values are equally probable, then the entropy of the message is log (n). In the present paper, we discuss the expectation value of the entropy, for an arbitrary probability distribution. We introduce a mixture of all possible probability distributions.

Finite Elements in Time and Space
The Aeronautical Journal, 1969The present paper seeks to apply the ideas of discretisation to time dependent phenomena. As a suitable variational statement we may use Hamilton's principle. In practise this means that the time is discretised into a set of finite elements which are taken to be the same for all structural elements.

Necessary and sufficient conditions are given for the solution of the ordinary differential equation \(d^ 2x/dt^ 2=g(x,\dot x)\) from an initial point \((x_ 0,\dot x_ 0)\in R^ 2\) to arrive at (0,0) in finite time, where \(g(0,0)=0\), and g is C except at (0,0) where it is continuous.

Distributed Finite-Time Optimization
2018 IEEE 14th International Conference on Control and Automation (ICCA), 2018In this paper, we consider the distributed optimization problem of multi-agent systems. The objective is to minimize the global objective function, which is the sum of local objective functions, by using local communication and local computation. We develop a distributed proportional-integral (PI) algorithm, based on the information received from its ...
