Porous silica has been extensively used as suitable carrier for the immobilization of various enzymes. Randomly Methylated β-Cyclodextrin (RaMeβCD) surface active properties and very high solubility in water could therefore be template fabrication particles with tunable pore size. Silica were prepared by sol-gel process alkaline medium without use RaMeβCD. Lipase Bfrom Candida antarctica (CALB)...

A large number of network security breaches in IoT networks have demonstrated the unreliability current Network Intrusion Detection Systems (NIDSs). Consequently, interruptions and loss sensitive data occurred, which led to an active research area for improving NIDS technologies. In analysis related works, it was observed that most researchers aim obtain better classification results by using a...

In this paper, we give a conditional lower bound of n on running time for the classic k-median and k-means clustering objectives (where n is the size of the input), even in lowdimensional Euclidean space of dimension four, assuming the Exponential Time Hypothesis (ETH). We also consider k-median (and k-means) with penalties where each point need not be assigned to a center, in which case it mus...

A high-speed low power scalable programmable dual modulus digital CMOS frequency divider architecture is proposed. The unique frequency divider architecture includes a high speed parallel counter with State Excitation Module, a switchover trigger circuit, a modulus switchover circuit and a reloader circuit. The mode switchover circuit has two sets of external programmable inputs for two alterna...

In the online bipartite matching problem with replacements, all the vertices on one side of the bipartition are given, and the vertices on the other side arrive one by one with all their incident edges. The goal is to maintain a maximum matching while minimizing the number of changes (replacements) to the matching. We show that the greedy algorithm that always takes the shortest augmenting path...

This paper investigates, theoretically, the temperature dependence of the performance of solar cells in the temperature range 273–523 K. The solar cell performance is determined by its parameters, viz., short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF) and efficiency (Z). Solar cells based on semiconductor materials such as Ge, Si, GaAs, InP, CdTe and CdS are con...

BACKGROUND Molecular mechanisms underlying the deterioration of patients undergoing LV assist device (LVAD) implantation remain poorly understood. We studied the cytokines tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta and IL-6 and the terminal stage of the apoptotic pathway in patients with decompensating heart failure who required LVAD support and compared them with patients wit...

The inhibitor of caspase-3-activated DNase (ICAD) is a caspase-3 substrate that controls nuclear apoptosis. ICAD has two isoforms: a functional isoform of M(r) 45,000, ICAD-L/DNA fragmentation factor (DFF) 45; and a M(r) 35,000 isoform, ICAD-S/DFF35. ICAD-deficient murine cells display resistance to apoptotic stimuli and absence of typical nuclear changes of apoptosis. Our aim was to: (a) chara...

Die Workshops Software Reengineering (WSR) wurden mit dem ersten WSR 1999 ins Leben gerufen, um neben den internationalen erfolgreichen Tagungen im Bereich Reengineering auch ein deutschsprachiges Diskussionsforum zu schaffen. Ziel der Treffen ist es, einander kennen zu lernen und auf diesem Wege eine direkte Basis der Kooperation zu schaffen, so dass das Themengebiet eine weitere Konsolidierun...

In the reordering buffer management problem, a sequence of colored items arrives at a service station to be processed. Each color change between two consecutively processed items generates some cost. A reordering buffer of capacity k items can be used to preprocess the input sequence in order to decrease the number of color changes. The goal is to find a scheduling strategy that, using the reor...
