The speech transmission index (STI) and room acoustic parameters (RAPs) are essential metrics for assessing quality predicting listening difficulty in a sound field. Although STI important RAPs, such as reverberation time clarity, can be derived from the impulse response (RIR), measuring RIR regularly occupied spaces is difficult. Hence, simultaneous blind estimation of RAPs an imperative chall...

The wave characteristics of unexplained rapping sounds have been studied and compared with similarsounding raps produced using normal tapping methods. Differences in low frequency wave properties between the two classes of raps have been noted. There are indications that the acoustic properties of the two classes of sounds are different and that this technique can be used to differentiate betwe...

Objective: This study explored the effects of polysaccharides (RAPD) extracted from traditional anti-stone Chinese medicine Rhizoma alismatis and their carboxymethylated derivatives (RAPs) on crystal phase, morphology, size calcium oxalate (CaOx). It also determined damaging ability regulated crystals human renal tubular epithelial cells (HK-2). Methods: RAPD carboxymethylation with a carboxyl ...

We propose a new algorithm for recommender systems with numeric ratings which is based on Pattern Structures (RAPS). As the input the algorithm takes rating matrix, e.g., such that it contains movies rated by users. For a target user, the algorithm returns a rated list of items (movies) based on its previous ratings and ratings of other users. We compare the results of the proposed algorithm in...

Defines a vocabulary for scaleable systems: Geoplexes, Farms, Clones, RACS, RAPS, clones, partitions, and packs and dicusses the design tradeoffs of using clones, partitons, and packs.

A resource allocation problem (RAP) is encountered in a variety of areas in operations research and management science. It is generally treated as a combinatorial optimization problem, where a limited amount of resources are to be allocated to certain number of competitive events in order to achieve the most effective allotment of the resources. An RAP usually contains a huge number of integer ...

Cloud radio access network (C-RAN) has become a promising network architecture to support the massive data traffic in the next generation cellular networks. In a C-RAN, a massive number of low-cost remote antenna ports (RAPs) are connected to a single baseband unit (BBU) pool via high-speed low-latency fronthaul links, which enables efficient resource allocation and interference management. As ...

The receptor-associated prorenin system (RAPS) refers to the pathogenic mechanism whereby prorenin binding to the (pro)renin receptor [(P)RR] dually activates the tissue renin-angiotensin system (RAS) and RAS-independent intracellular signaling. Here we revealed significant upregulation of prorenin and soluble (P)RR levels in the vitreous fluid of patients with uveitis compared to non-inflammat...
