Umbelliprenin is a prenylated compound, which belongs to the class of sesquiterpene coumarins. It is extracted from dried roots of Ferula szwitsiana collected from the mountains of Golestan forest (Golestan Province, north of Iran). Induction of apoptosis in Jurkat T-CLL cells has been previously shown. In this study, effect of umbelliprenin on proapoptotic caspases (caspase-8 and -9) and antia...

We develop and evaluate a novel data compression strategy for visual SLAM centered on traveled trajectory analysis. Beyond compressing scene structure based purely on geometrical information as commonly done, we aim at developing representations that are useful for re-exploration, that use low memory footprint and low CPU computation. Our work is evaluated on data collected from a visual sensor...

We present geometric simulations on a zeolite framework (faujasite) with extra-framework methanol and water contents explicitly present. We distinguish the intrinsic flexibility window of the framework from the newly defined extrinsic window limited by host-guest steric interactions. The extrinsic flexibility window can be limited not only in compression, but also in expansion, as the beta-cage...

We present Angle-Analyzer, a new single-rate compression algorithm for triangle-quad hybrid meshes. Using a carefully-designed geometry-driven mesh traversal and an efficient encoding of intrinsic mesh properties, AngleAnalyzer produces compression ratios 40% better in connectivity and 20% better in geometry than the leading Touma and Gotsman technique for the same level of geometric distortion...

In this work, a transition process in hypersonic flow over cold-wall compression ramp is studied using direct numerical simulation (DNS) and global stability analysis (GSA). The free-stream Mach number the Reynolds based on flat-plate length are 7.7 $8.6 \times 10^5$ , respectively. shock-induced pressure rise causes boundary layer to separate flat plate, forming separation bubble around corner...

We study the problem of compressing massive tables within the partition-training paradigm introduced by Buchsbaum et al. [SODA’00], in which a table is partitioned by an off-line training procedure into disjoint intervals of columns, each of which is compressed separately by a standard, on-line compressor like gzip. We provide a new theory that unifies previous experimental observations on part...

The compression efficiency of a rolling piston type rotary compressor for room airconditioners was analyzed, Suction passage loss is one of the detracting factors in compression efficiency and we studied its main cause, i.e. the pressure pulsation generated in the suction line, and clarified the relation between suction line specification and suction passage loss. A method of evaluating the suc...

Modern processors use two or more levels of cache memories to bridge the rising disparity between processor and memory speeds. Microprocessor designers have been torn between tight constraints on the amount of onchip cache memory and the high latency of off-chip memory, such as dynamic random access memory. Accessing off-chip memory generally takes an order of magnitude more time than accessing...

We report on the fabrication of high-Q, fused-quartz microresonators and the parametric generation of a frequency comb with 36-GHz line spacing using them. We have characterized the intrinsic stability of the comb in both the time and frequency domains to assess its suitability for future precision metrology applications. Intensity autocorrelation measurements and line-by-line comb control reve...

This paper describes a method for formal compression of fuzzy systems. This method compresses a fuzzy system with an arbitrarily large number of rules into a smaller fuzzy system by removing the redundancy in the fuzzy rule base. As a result of this compression, the number of on-line operations during the fuzzy inference process is significantly reduced without compromising the solution. This r...
