Pancreatic lipase is the enzyme responsible for digestion and absorption of triglycerides, being its inhibition one of the widest studied methods used to determine the potential activity of natural products to inhibit dietary fat absorption. Decrease of energy intake from dietary fat through inhibition of this enzyme may be an excellent strategy to prevent and treat obesity. The inhibitory acti...

In this note, we investigate the performance of the PCM scheme with linear quantization rule for quantizing unit-norm tight frame expansions for R without the White Noise Hypothesis. In [4], Wang and Xu showed that for asymptotically equidistributed unit-norm tight frame the PCM quantization error has an upper bound O(δ(d+1)/2) and they conjecture the upper bound is sharp. In this note, we conf...

The thermal response characteristic of a hybrid cooler that is charged with a “dry” solid-solid phase change compound is evaluated. A mathematical model that simulates the performance of a cooler/heat storage unit is formulated. A prototype heat sink that incorporates heat storage using a “dry” PCM is tested, and used to benchmark the simulation model. Different heating and cooling strategies a...

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...

A techrdqrre for pulse code modulation (PCM) encoding according to the 15-segment approximation to the P-255 krw is deseribed. The technique makes possible the realization of a one-channel encoder together with the associated sample/hold function as a single NMOS integrated circuit. The requirements imposed on the individual components for satisfactory system performance are investigated, and i...

Phase change materials are widely considered for application in nonvolatile memories because of their ability to achieve phase transformation in the nanosecond time scale. However, the knowledge of fast crystallization dynamics in these materials is limited because of the lack of fast and accurate temperature control methods. In this work, we have developed an experimental methodology that enab...

In this paper, an optimal control of quadratic performance index with nonlinear constrained is presented. The sine-cosine wavelet operational matrix of integration and product matrix are introduced and applied to reduce nonlinear differential equations to the nonlinear algebraic equations. Then, the Newton-Raphson method is used for solving these sets of algebraic equations. To present ability ...

The use of intensive patient-centered management (PCM) for managed care patients with life-limiting diagnosis and multiple comorbid conditions (“complex patients”) can sharply reduce costs and utilization while increasing patient satisfaction. PCM also improves reported quality of life with no adverse effects on survival, a recent study has shown. “Patient-centered management is an emerging, co...

The incorporation of phase change materials (PCM) in buildings has the potential to enhance thermal efficiency buildings, reduce energy cost, shift peak load, and eventually air pollution mitigate global warming. However, initial capital cost PCM is still high, thus establishment a control strategy become essential optimize its use an effort lower investment costs. In this paper, extensive revi...

This communication reports a new theranostic system with a combination of capabilities to both enhance the contrast of photoacoustic (PA) imaging and control the release of a chemical or biological effector by high-intensity focused ultrasound (HIFU). The fabrication of this system simply involves filling the hollow interiors of gold nanocages with a phase-change material (PCM) such as 1-tetrad...
