The notions of an event horizon, (EH), and stationary limit surface, (SLS), are important concepts in black hole physics. The former requires no comment, while the latter is less well-known. The SLS geometrically bounds a region outside the EH known as an ergosphere. Inside the ergosphere a test particle cannot travel along the orbit of a timelike Killing vector and remain at rest, and the red ...

Stochastic Local Search (SLS) solvers are considered one of the best solving technique for randomly generated problems and more recently also have shown great promise for several types of hard combinatorial problems. Within this work, we provide a thorough analysis of different implementation variants of SLS solvers on random and on hard combinatorial problems. By analyzing existing SLS impleme...

Although the toxicity of streptolysin O (SLO) and streptolysin S (SLS) in purified group A streptococci (GAS) has been established, the effect of these molecules in natural infection is not well understood. To identify whether biologically relevant concentrations of SLO and SLS were cytotoxic to epithelial and phagocytic cells that the bacteria would typically encounter during human infection a...

In this project, Entropic will serve as a technology transfer agent for the Speech and Language Systems (SLS) program. Our ultimate goal is to make complete systems developed in the course of SLS research readily available to interested parties in government, education, and industry. An intermediate goal is to provide clean, well documented implementations of speech recognition systems such as ...

Single-crystalline Cd3P2 nanowires (NWs) have been synthesized via a solution-liquid-solid (SLS) mechanism. The lengths of the resulting nanowires can be effectively tuned in the range of 180 nm and 5 μm, and the photodetectors made of the Cd3P2 nanowires exhibited a pronounced photoresponse with high stability and reproducibility.

Dynamic service level negotiation is necessary to flexibly allocate resources according to QoS demands of a host or a domain. We have designed COPS-SLS as a service level negotiation protocol for IP-based networks. In this paper, we analyse a COPS-SLS-based negotiation system from the protocol design and system’s scalability perspectives. This analysis is useful not only to the improvement of t...

The admissibility analysis and robust admissible control problem of the uncertain discretetime switched linear singular (SLS) systems for arbitrary switching laws are investigated. Based on linear matrix inequalities, some sufficient conditions are given for: A) the existence of generalized common Lyapunov solution and the admissibility of the SLS systems for arbitrary switching laws, B) the ex...

The advent of image-guided, laparoscopic surgery in the United States began quietly enough in the 1960's. Certainly, the laparoscope was used for diagnostic and therapeutic purposes before then, but its use was limited. The marriage in 1960 of the Hopkin's rod-lens system and Storz laparoscope with its fiberoptic light delivery system enabled physicians to view body cavities with greater illumi...

A multipurpose beamline for tests and developments in the field of x-ray optics and synchrotron radiation instrumentation in general is under construction at the Swiss Light Source (SLS) bending magnet X05DA. The beamline uses a newly developed UHV compatible, 100 μm thick, brazed CVD diamond vacuum window. The very compact cryogenically cooled channel cut Si(111) monochromator and bendable 1:1...

Objectives: Virtual reality is a new technology that has been recently used for different purposes in the rehabilitation of children. This study aimed to investigate the effectiveness of this method in balance rehabilitation of children with Cerebral Palsy (CP). Methods: This was an A-B-A design single subject study in which 3 children with hemiplegic CP participated. The baseline phase and in...
