Mortality: a physics perspective
(2021)
One of the many interests of the late Dietrich Stauffer was the modelling of mortality. Here we review the features of mortality data for various biological species. Age specific mortality (death rate) leads to a discussion ...
Pressure Dependent Mechanical Properties of Thin Films under Uniaxial Strain via the Layer Compression Test
(2023)
Amorphous materials can exhibit strong nonlinear mechanical properties in comparison to crystalline metals and ceramics, largely due to their non equilibrium state which depends on the means of sample preparation history. ...
High-Mobility Flexible Transistors with Low-Temperature Solution-Processed Tungsten Dichalcogenides
(2023)
The investigation of high-mobility two-dimensional (2D) flakes beyond molybdenum disulfide (MoS2) will be necessary to create a library of high-mobility solution-processed networks that conform to substrates and remain ...
Optimizing performance of quantum operations with non-Markovian decoherence: the tortoise or the hare?
(2024)
The interaction between a quantum system and its environment limits our ability to control it and perform quantum operations on it. We present an efficient method to find optimal controls for quantum systems coupled to ...
Spin transfer torque in Mn3Ga -based ferrimagnetic tunnel junctions from first principles
(2021)
We report on first-principles calculations of spin-transfer torque (STT) in epitaxial magnetic tunnel junctions (MTJs) based on ferrimagnetic tetragonal Mn3Ga electrodes, both as analyzer in a Fe/MgO stack, and also in an ...
Machine-learning semilocal density functional theory for many-body lattice models at zero and finite temperature
(2021)
We introduce a machine-learning density-functional-theory formalism for the spinless Hubbard model in one
dimension at both zero and finite temperature. In the zero-temperature case this establishes a one-to-one ...
Structural, optical, and electrical properties of silver gratings prepared by nanoimprint lithography of nanoparticle ink
(2021)
A facile method for fabrication of silver gratings using silver nanoparticle ink and nanoimprint lithography is investigated. The properties of silver nanoparticle ink grating and planar samples, with and without a PMMA ...
Characterising and control of ammonia emission in microbial fuel cells
(2020)
The serious ammonia (NH3) emission of air-cathode microbial fuel cells (MFCs) was reported but how to control and mitigate the emission hasn’t been well studied. Considering the importance of the issue for the application ...
Neutron Imaging of Paramagnetic Ions: Electrosorption by Carbon Aerogels and Macroscopic Magnetic Forces
(2021)
The electrosorption of Gd3+ ions from an aqueous 70 mM Gd(NO3)3 solution in monolithic carbon aerogel electrodes was recorded by dynamic neutron imaging. The aerogels have a bimodal pore size distribution consisting of ...
