The shift team formation problem in multi-shift manufacturing operations [PDF]

This paper addresses the problem of assigning operators to teams that work in single-, two-, or three-day shift systems. The problem was motivated by, and illustrated with a case situation encountered in Dutch manufacturing industry.

Peak Shift in Remembering [PDF]

, 2003
If remembering is discriminative behaviour along the dimension of time and if, as Sargisson and White (2001) argued, generalisation around a peak can occur in this behaviour, then the peak shift which has been shown in discrimination along so many other ...

Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]

, 2012
We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...

High-Efficiency Stacked Half-Bridge Sigma Topology for Wide Input Range and High Step-Down Application

IEEE Open Journal of Power Electronics
In wide input range and high step-down application, conventional Sigma converter suffers from the problem of small duty cycle and low efficiency of the internal Buck converter.

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Improved Detection of Differential Phase Shift Keying through MultiSymbol

, 2005
We report an improved self-homodyne detection scheme for differential phase-shift-keying that achieves close to homodyne performance and effectively reduces the influence of nonlinear phase noise, resulting in a 1.3dB sensitivity improvement over self ...

Phase jitter dynamics of first-order digital phase-locked loops with frequency-modulated input [PDF]

, 2008
IEEE International Symposium on Circuits and Systems (ISCAS), Seattle, USA, 18-21 May 2008Inherent to digital phase-locked loops is frequency quantization in the number-controlled oscillator which prevents the loop from locking exactly onto its reference

Iterative learning control: algorithm development and experimental benchmarking

, 2009
This thesis concerns the general area of experimental benchmarking of Iterative Learning Control (ILC) algorithms using two experimental facilities. ILC is an approach which is suitable for applications where the same task is executed repeatedly over the

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
