Further improvement of storage density is a key challenge for the application phase-change memory (PCM) in storage-class memory. However, PCM, improvements include feature size scaling down and multi-level cell (MLC) operation, potentially causing thermal crosstalk issues phase separation issues, respectively. To address these challenges, we propose high-aspect-ratio (25:1) lateral nanowire (NW...

The cell formation (CF) is one of the most important steps in the design of a cellular manufacturing system (CMS), which it includes machines’ grouping in cells and part grouping as separate families, so that the costs are minimized. The various aspects of the problem should be considered in a CF. The machine reliability and the tool assigned to them are the most important problems which have t...

Distributed waste-to-hydrogen (WtH) systems are a potential solution to tackle the dual challenges of sustainable waste management and zero emission transport. Here we propose concept distributed WtH based on gasification fermentation support hydrogen fuel cell buses in Glasgow. A variety scenarios were configured biomass feedstock, production reactors, upstream downstream system components. co...

BACKGROUND The American Academy of Pediatrics and the American Medical Association recommend storing firearms unloaded and locked up to minimize the chance of injury. Although these recommendations appeal to common sense, no study has yet addressed whether firearm storage practices influence the risk of unintentional firearm injury. METHODS Negative binomial regression analyses were used to a...

OBJECTIVE To determine the household prevalence of firearms in Pennsylvania, and describe the storage practices for these weapons. DESIGN A statewide telephone survey of 3,620 Pennsylvania adults selected from households by random digit dialing in 1994. MAIN OUTCOME MEASURES Firearm ownership and storage practices were computed by household characteristics using logistic regression. RESUL...

To study the fundamental energy storage mechanism of photovoltaically self-charging cells (PSCs) without involving light-responsive semiconductor materials such as Si powder and ZnO nanowires, we fabricate a two-electrode PSC with the dual functions of photocurrent output and energy storage by introducing a PVDF film dielectric on the counterelectrode of a dye-sensitized solar cell. A layer of ...

In this paper, we d e v elop an analysis of the so-called Dual Spacer. In contrast to a conventional spacer, which shapes a traac stream only according to a given Peak Cell Rate, the Dual Spacer takes into account the Peak Cell Rate as well as the Sustainable Cell Rate with the corresponding Burst Tolerance. By shaping, also according to a Sustainable Cell Rate, the Usage Parameter Control func...

In this paper, we present the mode-locked operation of an ultra-robustly stabilised Nd:GdVO(4) laser with low repetition rate by combining quadratic polarisation switching and a semiconductor saturable absorber mirror (SESAM). In addition, similar experiment was also done with Nd:YVO(4). For Nd:GdVO(4), 16-ps pulses at 1063 nm with a repetition rate of 3.95 MHz have been obtained for a laser av...

Abstract Introduction: Isolated perfused heart models such as perfusion and superfusion are commonly used for mammalian heart research. However, there are several fundamental limitations in the current techniques. In perfusion model, a suitable cannula is connected to the aorta and the perfusion is retrogradely performed. But, electrode displacement is a potential unwanted event resulted fr...
