Motivated by the structure of social networks, this paper initiates a study of distributed algorithms in networks that exhibit a core-periphery structure. Such networks contain two distinct groups of nodes: a large and sparse, group identified as the periphery, which is loosely organized around a small, and densely connected group identified as the core. We identify four basic properties that a...

Rosa pimpinellifolia, commonly known as the burnet rose, has shown huge functional properties and industrial potential. In this present study, convective drying process was optimized to enhance quality, antioxidant activity, phenolic compounds. The influence of conditions on rehydration kinetics mathematical modeling R. pimpinellifolia fruit (black rose hips) were investigated. Response surface...

La cáscara de cacao es un residuo agrícola que puede ser valorizado gracias a la presencia compuestos bioactivos tales como los polifenoles; importancia éstos últimos radica en se ha probado tienen efecto positivo para salud por sus propiedades antioxidantes y antirradicalarias. Para el procesamiento, normalmente llevada una etapa secado antes extracción; sin embargo, escala industrial implemen...

Naor, Parter, and Yogev [SODA 2020] recently designed a compiler for automatically translating standard centralized interactive protocols to distributed protocols, as introduced by Kol, Oshman, Saxena [PODC 2018]. In particular, using this compiler, every linear-time algorithm deciding the membership some fixed graph class can be translated into dMAM(O(logn)) protocol class, that is, with O(log...

Lactose-free probiotic powders were obtained by mixing Bifidobacterium BB-12 suspensions with lactose-free milk powder or and prebiotics (inulin oligofructose). A thorough investigation was performed to know their water sorption properties physical thermal characteristics. By evaluating the properties, Peleg model fitted well experimental data, showing that equilibrium moisture content of incre...

Non-stationary signals, i.e. signals whose spectral content varies with time, are very common in many signal processing applications. Examples include, but are not limited to, communications, sonar, radar, vibration, ultrasound imaging, speech and biological signals. Many methods of analysis of non-stationary signals focus on nonparametric time-frequency distributions. However these suffer from...

The amino acid sequence of the rat 60 S ribosomal subunit protein L13a was deduced from the sequence of nucleotides in two recombinant cDNAs. Mature ribosomal protein L13a has 202 amino acids (the NH2-terminal methionine is removed after translation of the mRNA) and a M(r) of 23,330. Hybridization of the L13a cDNA to digests of nuclear DNA suggests that there are 9-11 copies of the L13a gene. T...

There has been significant success in designing highly efficient algorithms for distance and shortest-path queries in recent years; many of the state-of-the-art algorithms use the hub labeling framework. In this paper, we study the approximability of the Hub Labeling problem. We prove a hardness of Ω(log n) for Hub Labeling, matching known approximation guarantees. The hardness result applies t...

Secure multi-party computation (MPC) is a central problem in cryptography. Unfortunately, it is well known that MPC is possible if and only if the underlying communication network has very large connectivity — in fact, , where is the number of potential corruptions in the network. This impossibility result renders existing MPC results far less applicable in practice, since many deployed network...
