A coarse-grained, rigid-rod model that includes steric interactions and an internal dipole is used to study monolayers of surfactant molecules tethered to a flat interface. Monte Carlo simulations are performed in the canonical ensemble for a range of high-density configurations with varying degrees of dipole strength. Both a melting transition and a tilting transition are observed, and the dep...

We introduce a new category C, which we call the cluster category, obtained as a quotient of the bounded derived category D of the module category of a finite-dimensional hereditary algebra H over a field. We show that, in the simply-laced Dynkin case, C can be regarded as a natural model for the combinatorics of the corresponding Fomin–Zelevinsky cluster algebra. In this model, the tilting obj...

[Purpose] This systematics review was undertaken to synthesize what is known regarding pelvifemoral rhythm, that is, the coordinated flexion of the thigh and posterior tilting of the pelvis during hip flexion (HF). [Methods] Three databases were searched. [Results] Nine relevant articles were identified via independent database searches and a hand search by the authors. The articles were consis...

I this paper, we propose a fast adaptive importance sampling method for the efficient simulation of buffer overflow probabilities in queueing networks. The method comprises three stages. First, we estimate the minimum cross-entropy tilting parameter for a small buffer level; next, we use this as a starting value for the estimation of the optimal tilting parameter for the actual (large) buffer l...

The aim of this study was to investigate whether and which aspects of a concurrent motor activity can facilitate children's and adults' performance in a dynamic imagery task. Children (5-, 7-, and 9-year-olds) and adults were asked to tilt empty glasses, filled with varied amounts of imaginary water, so that the imagined water would reach the rim. Results showed that in a manual tilting task wh...

Quantitative Accelerated Life Testing (QALT) is a solution for assessing thereliability of Micro Electro Mechanical Systems (MEMS). A procedure for QALT is shownin this paper and an attempt to assess the reliability level for a batch of MEMSaccelerometers is reported. The testing plan is application-driven and contains combinedtests: thermal (high temperature) and mechanical stress. Two variant...

In this study we contribute towards establishing the process-microstructure relationships in thin films grown off-normally by ionized physical vapor deposition. High power impulse magnetron sputtering (HiPIMS) is used at various peak target powers and deposition rates to grow copper (Cu) and chromium (Cr) films from a cathode placed at an angle 90 degrees with respect to the substrate normal. F...

We report the findings of a panEuropean study on the factors which provoke motion sickness on tilting trains. The findings also highlight tactics passengers may use to ameliorate their malaise. Some readers may recall that the tilting train programme under development in the UK some 30 years ago was halted because of a combination of technical problems and reports of high levels of motion sickn...

This study aims to explore gating mechanisms of mechanosensitive channels in terms of membrane tension, membrane adaptation, protein conformation, and energetics. The large conductance mechanosensitive channel from Mycobacterium tuberculosis (Tb-MscL) is used as a model system; Tb-MscL acts as a safety valve by releasing small osmolytes through the channel opening under extreme hypoosmotic cond...
