TVM: Tabular VM migration for reducing hop violations of service chains in cloud datacenters (2017)

Network Function Virtualization is a recent and significant development applied in cloud datacenters, which can help service providers manage network services more flexibly and economically than using middle-boxes. User requests may demand different numbers of services in a chain, where the related flows can be directed to different physical machines (PMs) hosting required virtual network functions (VNFs) in a designated order. Sometimes, with the limited resources in current PMs, the deployment of service chains may result in great hop counts and cause hop (latency) violations against the service level agreements (SLAs) of user requests. Therefore, we propose a dynamic service-chain management approach called Tabular VM Migration (TVM) to reduce hop violations of service chains in cloud datacenters. Different from other VM management policies, TVM considers the order of a set of VMs in a service chain and migrates key VMs which may cause hop violations onto the selected PMs. Thus, hop violations are reduced with few migrations. Simulation results indicate that TVM performs better than other common VM management policies, and reduce at most 16.68% of total number of hop violations induced by a static deployment approach (SOVWin).
Activation of mammalian gene expression by the UV component of sunlight – from models to reality (1996)

Ultraviolet radiation activates the expression of a wide variety of genes, by pathways which differ between the short non-solar ultraviolet C (UVC) wavelengths, which are strongly absorbed by nucleic acids, and the long solar ultraviolet A (UVA, 320-380 nm) wavelengths, which generate active oxygen intermediates. Intermediate solar ultraviolet (UV) wavelengths in the UVB (290-320 nm) range also contain an oxidative component, but more closely resemble UVC in their gene activating properties. Short wavelength UV, in common with other extracellular stimuli including growth factors, activates signal transduction events that involve both stress- and mitogen-activated protein kinase cascades. The extrapolation of the complex modulation of gene expression that ensues to the consequences of natural UV exposure requires careful attention to the details of doses and wavelength employed in the model experiments. Nevertheless, there is evidence that UVB irradiation of skin can activate the expression of proteins including immunomodulating cytokines, ornithine decarboxylase and, to a limited extent, nuclear oncogene products, as well as lead to stabilisation of p53. Non-cytotoxic doses of UVA radiation also lead to the strong activation of several genes which would be expected to have functional relevance in vivo.

Both principles and experimental results are presented.
System software techniques for low-power operation in wireless sensor networks (2005)

The operation of wireless sensor networks is fundamentally constrained by available energy sources. The underlying hardware determines the power draw of each possible mode of operation. System software attempts maximize the use of the lowest possible modes of each of the subsystems. This tutorial paper describes the system software techniques used at several levels. At the application sensing level, this includes duty-cycling, sensor hierarchy, and aggregation. At the communication level, it includes low-power listening, communication scheduling, piggybacking, post-hoc synchronization, and power-aware routing. At the node OS level, it includes event driven execution with split-phase operation and cooperative power management interfaces. At the lowest level, it includes management of primary and secondary energy storage devices coupled with intelligent charge transfer scheduling. All of these aspects must be integrated in a systematic software framework.

FPGA Implementation of Digital Modulation Techniques BPSK and QPSK using HDL Verilog (2017)

In the wireless communication system, to transfer the data without loss and to reduce size of antenna, modulation is the most important technique. Phase-shift keying (PSK) is a modulation technique in which the phase of a transmitted signal varies to convey information. Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) are implemented in Field Programmable Gate Array (FPGA). The proposed designs are aimed for study purposes. These digital modulators are designed using Verilog Hardware Description Language (HDL). Cadence's NC-Sim simulation software is used to check the functionality of designs. Xilinx's integrated software Environment (ISE) used for FPGA design implementation.
Which is the best algorithm for virtual machine placement optimization? (2017)

Summary One of the key problems for Infrastructure‐as‐a‐Service providers is finding the optimal allocation of virtual machines on the physical machines available in the provider's data center. Since the allocation has significant impact on operational costs as well as on the performance of the accommodated applications, several algorithms have been proposed for the virtual machine placement problem. So far, no objective comparison of the proposed algorithms has been provided; therefore, it is not known which one works best or what factors influence the performance of the algorithms. In this paper, we present an environment and methodology for such comparisons and compare 7 different algorithms using the proposed environment and methodology. Our results showcase differences of up to 66% between the effectiveness of different algorithms on the same real‐world workload traces, thus underlining the importance of objectively comparing the performance of competing algorithms.

Peanut Sensitivity (1989)

Peanuts are one of the most allergenic foods. The allergic reactions may vary in severity from mild urticaria to severe anaphylactic episodes and death. The prevalence of peanut sensitivity is unknown, but it may affect as many as 10% of allergic individuals. The chemistry of peanut proteins has been extensively studied. Two major protein fractions have been prepared from saline extracts of peanut flour, arachin and conarachin. A major peanut allergen termed "Peanut-1" has been isolated. However, a number of protein constituents, including the arachin and conarachin fractions, have been shown to be allergenic. The ability to diagnose peanut sensitivity accurately has been hampered by the lack of standardized peanut extracts. However, efforts are under way to prepare such standardized reagents. Treatment consists of avoiding peanut protein products and using self-administered epinephrine. A number of peanut protein-containing products are allergenic, although peanut oil is not. The peanut-allergic consumer should be instructed to carefully read labels of foods. This can at times, however, be misleading, because certain foods may be inadvertently contaminated by peanut proteins.
The value of amino-terminal propeptide of type III procollagen in routine screening for methotrexate-induced liver fibrosis: a 10-year follow-up (2001)

Present data support the view that, as long as PIIINP is consistently normal in serial investigations, there is minimal risk of development of substantial liver fibrosis.
Evaluation of Relay-Enhanced LTE-Advanced Networks (2011)

The Third Generation Partnership Program's Long-Term Evolution Advanced (3GPP LTE-Advanced) group is developing a new standard for mobile broadband access that will meet the throughput and coverage requirements of a fourth generation cellular technology. The key goals for this evolution are increased data rate, improved spectrum efficiency, improved coverage and reduced latency. The ultimate results of these goals are significantly improving service provisioning and reduction of operator costs for different traffic scenarios. One of the main challenges faced by the developing standard is providing high throughput at the cell edge. Cell edge performance is becoming more important as cellular systems employ higher bandwidths with the same amount of transmit power and use higher carrier frequencies with infrastructure designed for lower carrier frequencies. One solution to improve coverage is to use the fixed relays to transmit data between the Base Stations and the Mobile Stations or User Equipments through multi hop communication. For this reason, relay technologies have been actively studied and considered in the standardization process of next-generation mobile broadband communication system. As a next-generation 3GPP standard, LTE-Advanced exclusively takes the relay technology into account. This thesis focuses the relay technologies for the LTE-Advanced systems and evaluates the performance of the relay-enhanced LTE-Advanced network. The approach for this work is to design several environments for LTE-Advanced networks involving relays. Incorporating the channel model from the Wireless World Initiative New Radio (WINNER) project, four environments were designed among which one environment considers no relay at all and the rest of the environments considered relay deployments. And the performances of all the environments are evaluated in terms of Symbol Error Rate (SER) versus the Signal to Noise Ratio (SNR), under several different scenarios defined in WINNER project. As an outcome, the simulation results from the simulator show that relay technologies can effectively improve service performance.
A small RNA downregulates LamB maltoporin in <i>Salmonella</i> (2007)

In Escherichia coli and Salmonella enterica, activation of sigma(E)-dependent envelope stress response leads to the abrupt decline in the synthesis of all major outer membrane proteins (OMPs). Recent studies found that two sigma(E)-controlled small RNAs (sRNAs), MicA and RybB, downregulate a number of OMPs. While RybB targets several different mRNAs, including ompC and ompD, MicA was up to date thought to act solely on ompA. Here we present evidence showing that MicA downregulates a second Salmonella OMP: LamB maltoporine. In strains overexpressing sigma(E), MicA accumulation leads to a significant decrease in LamB protein and mRNA levels, as well as a reduction in beta-galactosidase activity in a strain carrying a lamB-lacZ translational fusion. The latter findings provided the basis for a genetic screen that allowed isolating point mutations in the micA gene and in its sigma(E) promoter. All alleles obtained displayed their altered regulatory phenotype from their natural chromosomal location. LamB downregulation by MicA requires a functional Hfq protein. Besides this role, confined to sigma(E)-activated conditions, we show that loss of Hfq results in the accumulation of a lamB-malM dimeric precursor and of malM mRNA during unchallenged growth. This suggests that Hfq normally intervenes in a mechanism that uncouples expression of the malK-lamB-malM operon, causing the distal portion of the transcript to be clipped off and degraded.

Malignant childhood neoplasms in the western region of Saudi Arabia. (1981)

In a sample of 8 cases of solid malignant neoplasms occurring in children resident in the Western Region of Saudi Arabia the most important finding was a remarkable preponderance of lymphomas when compared with Western series. Other notable differences were the prevalence of Hodgkin's disease in the first decade of life, the different proportions of its subtype, and the occurrence of well-differentiated lymphocytic lymphoma. Included is a case of lympho-epithelioid cellular lymphoma (Lennert's lymphoma) which, as far as we can ascertain, is the youngest reported case. There was a relatively large number of embryonal rhabdomyosarcomas and a paucity of neuroblastomas. Our study, which is concerned with proportional rates (population studies are not yet completed), contributes to the interesting ethnic and geographical differences which exist in the prevalence of childhood lymphomas and other solid malignant neoplasms. The biases that affect studies such as ours are stressed.
TREE COMPRESSION AND OPTIMIZATION WITH APPLICATIONS (1990)

Different methods for compressing trees are surveyed and developed. Tree compression can be seen as a trade-off problem between time and space in which we can choose different strategies depending on whether we prefer better compression results or more efficient operations in the compressed structure. Of special interest is the case where space can be saved while preserving the functionality of the operations; this is called data optimization. The general compression scheme employed here consists of separate linearization of the tree structure and the data stored in the tree. Also some applications of the tree compression methods are explored. These include the syntax-directed compression of program files, the compression of pixel trees, trie compaction and dictionaries maintained as implicit data structures.
Two-level Data Prefetching (2007)

Data prefetching has been shown to be an effective tool in hiding part of the latency associated with cache misses in modern processors. Traditionally, data prefetchers fetch data into a small prefetch buffer near the L1 for low latency, or the L2 cache for greater coverage and less cache pollution. However, with the L1–L2 cache speed gap growing, significant performance gains can be obtained if the data prefetcher can operate as aggressively as an L2-level prefetcher but with the fast hit times of an L1-level prefetcher. In this paper, we propose a prefetching framework where an L1-level prefetcher and an L2level prefetcher work cooperatively to reduce the average access time more than either one alone can. We evaluate several design alternatives suited to perform synergistically under different workloads. From the insight we gather from this analysis, we propose a confidence-based adaptive prefetcher that can improve prefetch efficiency significantly with judicious use of available bus bandwidth. Our results show that for certain prefetcher combinations, twolevel prefetching can achieve the cumulative speedup attained from either prefetcher alone. Furthermore, when compared to other two-level prefetching models, the adaptive design provides similar speedups with appreciably less bus traffic.

Role of catalase on the hypoxia/reoxygenation stress in the hypoxia-tolerant Nile tilapia (2012)

The specific contribution of each antioxidant enzyme to protection against the reoxygenation-associated oxidative stress after periods of hypoxia is not well understood. We assessed the physiological role of catalase during posthypoxic reoxygenation by the combination of two approaches. First, catalase activity of Nile tilapias (Oreochromis niloticus) was 90% suppressed by intraperitoneal injection of 3-amino-1,2,4-triazole (ATZ, 1g/kg). In ATZ-injected fish, liver GSH levels, oxidative stress markers, and activities of other antioxidant enzymes remained unchanged. Second, animals with depleted catalase activity (or those saline-injected) were subjected to a cycle of severe hypoxia (dissolved O(2) = 0.28 mg/l for 3 h) followed by reoxygenation (0.5 to 24 h). Hypoxia did not induce changes in the above-mentioned parameters, either in saline- or in ATZ-injected animals. Reoxygenation increased superoxide dismutase activity in saline-injected fish, whose levels were similar to ATZ-injected animals. The activities of glutathione S-transferase, selenium-dependent glutathione peroxidase, and total-GPX and the levels of GSH-eq, GSSG, and thiobarbituric acid reactive substances remained unchanged during reoxygenation in both saline- and ATZ-injected fish. The GSSG/GSH-eq ratio in ATZ-injected fish increased at 30 min of reoxygenation compared with saline-injected ones. Reoxygenation also increased carbonyl protein levels in saline-injected fish, whose levels were similar to the ATZ-injected group. Our work shows that inhibition of liver tilapia catalase causes a redox imbalance during reoxygenation, which is insufficient to induce further oxidative stress. This indicates the relevance of hepatic catalase for hypoxia/reoxygenation stress in tilapia fish.
Reversible and Selective Interconversion of Hydrogen and Carbon Dioxide into Formate by a Semiartificial Formate Hydrogenlyase Mimic (2019)

The biological formate hydrogenlyase (FHL) complex links a formate dehydrogenase (FDH) to a hydrogenase (H<sub>2</sub>ase) and produces H<sub>2</sub> and CO<sub>2</sub> from formate via mixed-acid fermentation in <i>Escherichia coli</i>. Here, we describe an electrochemical and a colloidal semiartificial FHL system that consists of an FDH and a H<sub>2</sub>ase immobilized on conductive indium tin oxide (ITO) as an electron relay. These <i>in vitro</i> systems benefit from the efficient wiring of a highly active enzyme pair and allow for the reversible conversion of formate to H<sub>2</sub> and CO<sub>2</sub> under ambient temperature and pressure. The hybrid systems provide a template for the design of synthetic catalysts and surpass the FHL complex <i>in vivo</i> by storing and releasing H<sub>2</sub> on demand by interconverting CO<sub>2</sub>/H<sub>2</sub> and formate with minimal bias in either direction.
