Effect of the sample geometry on the second magnetization peak in single crystalline Ba$_{0.63}$K$_{0.37}$BiO$_3$ thick film

open access: yes, 1999
Magnetization hysteresis loop $M(H)$ measurements performed on a single crystalline Ba$_{0.63}$K$_{0.37}$BiO$_3$ superconducting thick film reveal pronounced sample geometry dependence of the "second magnetization peak" (SMP), i.e. a maximum in the width

Analysis and prediction of suspension force characteristics in a scalable groove-less hydrodynamic suspension micropump (GL-HSMP) prototype

open access: yesEngineering Applications of Computational Fluid Mechanics
Traditional contact-bearing pumps suffer from low power density. The reason is that inherent bearing wear issues restricts their rotational speed. Although hydrodynamic suspension pumps achieve wear-free operation at high speeds, existing designs rely on

Vortex Phase Diagram of weakly pinned YBa$_2$Cu$_3$O$_{7-\delta}$ for H $\parallel$ c

open access: yes, 2001
Vortex phase diagram in a weakly pinned crystal of YBCO for H $\parallel$ c is reviewed in the light of a recent elucidation of the process of `inverse melting' in a Bismuth cuprate system and the imaging of an interface between the ordered and the ...

Vortex Lattice Depinning vs. Vortex Lattice Melting: a pinning-based explanation of the equilibrium magnetization jump

open access: yes, 2000
In this communication we argue that the Vortex Lattice Melting scenario fails to explain several key experimental results published in the literature.

Dual‐Band Reconfigurable Antenna for Polarization Diversity

open access: yesInternational Journal of Antennas and Propagation, Volume 2018, Issue 1, 2018., 2018
This paper proposes a dual‐band reconfigurable square‐ring antenna with a polarization diversity property. The proposed antenna consists of a square‐ring resonator, two stubs with a shorting via, and two PIN diodes. The stub is positioned symmetrically to the left and right of the square‐ring resonator, and the square‐ring antenna connected to one of ...

Do editors have a silver bullet? an agent-based model of peer review [PDF]

open access: yes, 2014
This paper presents an agent-based model of peer review that looks at the effect of different editorial policies of referee selection. We tested four author/referee matching scenarios as follows: random selection of referees, selection of referees with a

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

open access: yesAdvanced Materials Technologies, Volume 10, Issue 23, December 3, 2025.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.

A semi-Markov model for price returns

open access: yes, 2011
We study the high frequency price dynamics of traded stocks by a model of returns using a semi-Markov approach. More precisely we assume that the intraday return are described by a discrete time homogeneous semi-Markov process and the overnight returns ...

Quality‐Related Process Monitoring Based on Total Kernel PLS Model and Its Industrial Application

open access: yesMathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013
Projection to latent structures (PLS) model has been widely used in quality‐related process monitoring, as it can establish a mapping relationship between process variables and quality index variables. To enhance the adaptivity of PLS, kernel PLS (KPLS) as an advanced version has been proposed for nonlinear processes.

Large-Area, Low-Noise, High Speed, Photodiode-Based Fluorescence Detectors with Fast Overdrive Recovery

open access: yes, 2005
Two large-area, low noise, high speed fluorescence detectors have been built. One detector consists of a photodiode with an area of 28 mm x 28 mm and a low noise transimpedance amplifier.
