Investigation of the order -disorder phase transition series in AuCu by in-situ temperature XRD and mechanical spectroscopy

Daniele Mari

In-situ temperature XRD and mechanical spectroscopy were applied to study phase transitions in AuCu alloy from the disordered FCC state (A1). The phase transition temperature intervals were investigated upon heating and cooling using a rate of 1 K/min in o ...

A Single-Phase, Proximal Path-Following Framework

Volkan Cevher, Quoc Tran Dinh, Anastasios Kyrillidis

We propose a new proximal path-following framework for a class of constrained convex problems. We consider settings where the nonlinear-and possibly nonsmooth-objective part is endowed with a proximity operator, and the constraint set is equipped with a se ...

INFORMS2018

We introduce a general formalism combining the coupled oscillator model with the transfer matrix method to analyze and engineer the phase of the light reflected from a Fano-resonant metasurface. This method accounts for periodicity and the presence of subs ...

Shaping of light fields behind amplitude and phase masks the basis the lithographic structure reproduction. The aerial image or better the intensity distribution defines the resolution of the structure to be printed. Contrast is the main parameter and to a ...

We evaluate the Brillouin frequency shift (BFS) determination error when using the Brillouin phase spectrum (BPS) instead of the Brillouin gain spectrum (BGS) in BOTDA setups. We compare the error obtained in the BFS determination in both cases, both with ...

Shaping of light behind masks using different techniques is the milestone of the printing industry. The aerial image distribution or the intensity distribution at the printing distances defines the resolution of the structure after printing. Contrast and p ...

The effect of the phase angle between the forewing and hindwing on the aerodynamic performance of a dragonfly-type ornithopter

Jamie Paik, Alice Ghislaine Concordel

Dragonflies achieve agile maneuverability by flapping four wings independently. Different phase angles between the flapping forewing and hindwing have been observed during various flight modes. The aerodynamic performance depends on phase angle control, as ...

Asynchronous Adaptation and Learning Over Networks—Part II: Performance Analysis

Ali H. Sayed

In Part I of this paper, also in this issue, we introduced a fairly general model for asynchronous events over adaptive networks including random topologies, random link failures, random data arrival times, and agents turning on and off randomly. We perfor ...

Momentum and photon energy dependence of the circular dichroic photoemission in the bulk Rashba semiconductors BiTeX (X = I, Br, Cl)

Marco Grioni, Arnaud Magrez, Oleg Yazyev, Helmuth Berger, Philippe Bugnon, Alberto Crepaldi, Gabriel Albert Autes, Luca Moreschini, Jens Christian Johannsen, Cédric Tournier-Colletta

Bulk Rashba systems BiTeX (X = I, Br, Cl) are emerging as important candidates for developing spintronics devices because of the coexistence of spin-split bulk and surface states, along with the ambipolar character of the surface charge carriers. The need ...

Manifestation of the spin textures in the thermopower of MnSi

László Forró, Ana Akrap, Stevan Arsenijevic

To identify possible spin texture contributions to thermoelectric transport, we present a detailed temperature and pressure dependence of thermopower S in MnSi, as well as a lowtemperature study of S in a magnetic field. We find that S/T reconstructs the ( ...
