Native support of multi-tenancy in RDBMS for software as a service (2011)

Software as a Service (SaaS) facilitates acquiring a huge number of small tenants by providing low service fees. To achieve low service fees, it is essential to reduce costs per tenant. For this, consolidating multiple tenants onto a single relational schema instance turned out beneficial because of low overheads per tenant and scalable manageability. This approach implements data isolation between tenants, per-tenant schema extension and further tenant-centric data management features in application logic. This is complex, disables some optimization opportunities in the RDBMS and represents a conceptual misstep with Separation of Concerns in mind.

New Charge-Steering Latches in 28nm CMOS for Use in High-Speed Wireline Transceivers (2018)

New charge-steering latches are proposed and simulated in 28nm FD-SOI CMOS for use in wireline transceivers. Three new latches demonstrate power savings of up to 40% when compared to conventional charge-steering latches. These latches achieve power savings through the addition of a switch in the pMOS cross-coupled pair which eliminates transistor power consumption when they are not required. All new latches demonstrate the ability to operate at data rates exceeding 28Gb/s, enabling a 56Gb/s SERDES when used in a half-rate architecture. Simulation results are also verified through analytical expressions.
Natural History of Sudden Sensorineural Hearing Loss (1977)

This is a prospective in-depth study of patients with sudden idiopathic sensorineural hearing loss. We found that 65% recover completely to functional hearing levels spontaneously and independent of any type of medical treatment. The majority do so within 14 days and many within the first few days. Prognosis can be predicted according to the slope of the initial audiogram (low-frequency losses do better than high-frequency losses), hearing at 8 kHz, erythrocyte sedimentation rates, in some select instances spatial disorientation symptoms, and speech discrimination scores. There was a very poor correlation between hearing and vestibular test abnormalities, except hypoactive calories. There were no correlations with age (excepting the very elderly), with antecedent respiratory infections, hypertension, diabetes, or other chronic diseases. We conclude that there is a fundamental difference in the behavior of apical and basal cochlea losses, that hearing recovery is always better at low than at high frequencies, that because of the high spontaneous recovery rates, tympanotomies seeking peri-lymph fistulas should be delayed ten days unless there is a progressive hearing loss, and that none of the current recommended treatments, especially histamine, have any effect on the outcome.
O2 radicals mediate reperfusion lung injury in ischemic O2-ventilated canine pulmonary lobe (1987)

This study was undertaken to determine whether lung injury after a period of ischemia reperfusion is caused by O2 ventilation during ischemia and whether this injury is mediated by reactive O2 metabolites. Isolated canine left lower pulmonary lobes were subjected to room temperature ischemia for 6 h while being ventilated with either 100% O2, room air, or 100% N2. After the ischemic period, all lobes were perfused with autologous blood and ventilated with 100% O2 for an additional 4 h. In lobes ventilated with 100% O2 during the ischemic period, massive weight gain (228%) occurred 4 h after reperfusion. A marked increase in pulmonary shunt was noted. Lobes ventilated with room air behaved similarly. In contrast, lobes ventilated with 100% N2 gained significantly less weight (54%) and did not manifest any increase in pulmonary shunt. When lobes ventilated with 100% O2 or room air were pretreated with superoxide dismutase (SOD), the injury was significantly reduced. Pressure-volume deflation study of lobes, after ischemia only, demonstrated that ventilation with 100% O2 and with 100% N2 both equally decreased pulmonary compliance. We conclude that lung ischemia-reperfusion injury is related to O2 ventilation during ischemia and that injury can be prevented by administration of SOD or ventilation with 100% N2. This suggests that the injury is related to O2 metabolites produced during O2 ventilation in the absence of the circulation.
Bedside Monitoring of Regionald Cortical Blood Flow in Comatose Patients Using Laser Doppler Flowmetry (1991)

Abstract Continuous bedside monitoring of regional cerebrocortical blood flow was carried out using laser Doppler flowmetry (LDF) in four comatose patients. Newly designed thin and flexible optical probes that were easily implanted into the cortex were employed. When the patients were in a deep comatose state, the recordings revealed a conspicuous relationship to intracranial pressure. As the patients improved, the flux values gradually increased, and the recordings showed characteristic changes in the wave pattern, presumably related to the restoration of an impaired cerebral autoregulation. Changes in regional cerebrocortical blood flow were also observed during routine nursing procedures, the use of medications, and voluntary activities, as demonstrated by one patient after a complete recovery. Although the volume of tissue scanned with LDF was limited, and the flux values did not directly express regionalf cerebrocortical blood flow in terms of milliliters per unit volume, changes in cerebral circulation were portrayed clearly in the flow recordings. Thus. LDF, which is simple to use. permits continuous bedside monitoring of the cerebral microcirculation. Its use should improve the management of comatose patients and also open avenues for a better understanding of the cerebral circulation in pathological states.
Design of a line-start synchronous reluctance motor (2013)

The design of line-start Synchronous Reluctance machines is proposed, based on the state of the art of motors designed for closed loop, vector control. The guidelines for overcoming the dilemma between synchronization capability and steady state performance are given, with examples of good and bad design choices. The proposed solutions compared via finite element analysis with a competitor induction motor in terms of efficiency and power factor. The finite element calculations are finally validated via experiments on a laboratory prototype.

Binding interactions between yeast tRNA ligase and a precursor transfer ribonucleic acid containing two photoreactive uridine analogs (1988)

Yeast tRNA ligase, from Saccharomyces cerevisiae, is one of the protein components that is involved in the splicing reaction of intron-containing yeast precursor tRNAs. It is an unusual protein because it has three distinct catalytic activities. It functions as a polynucleotide kinase, as a cyclic phosphodiesterase, and as an RNA ligase. We have studied the binding interactions between ligase and precursor tRNAs containing two photoreactive uridine analogues, 4-thiouridine and 5-bromouridine. When irradiated with long ultraviolet light, RNA containing these analogues can form specific covalent bonds with associated proteins. In this paper, we show that 4-thiouridine triphosphate and 5-bromouridine triphosphate were readily incorporated into a precursor tRNA(Phe) that was synthesized, in vitro, with bacteriophage T7 RNA polymerase. The analogue-containing precursor tRNAs were authentic substrates for the two splicing enzymes that were tested (endonuclease and ligase), and they formed specific covalent bonds with ligase when they were irradiated with long-wavelength ultraviolet light. We have determined the position of three major cross-links and one minor cross-link on precursor tRNA(Phe) that were located within the intron and near the 3' splice site. On the basis of these data, we present a model for the in vivo splicing reaction of yeast precursor tRNAs.

Heterogeneous Catalysts for the Guerbet Coupling of Alcohols (2013)

Alcohol coupling, also known as the Guerbet reaction, is a potentially important process to increase the value of short chain alcohols. Metal oxides, metal phosphates, and supported transition metals, such as copper, are important components of heterogeneous catalysts for the reaction. However, the wide variety of catalyst compositions, reaction conditions, and reactor configurations used to study the reaction complicate a direct comparison of various catalysts. In this review, rates over different catalysts will be compared, the influences of the acid and base properties of the catalyst on product selectivity will be presented, and possible reaction paths to accomplish alcohol coupling will be discussed.

FEM-based hybrid methods for the analysis of antennas on electrically large structures (2002)

In this paper, in-house developed 3D FEM/PO and FEM/UTD hybrid methods are presented. These techniques are shown to be accurate and efficient when they are applied to analyze antennas mounted on a large complex structure. The equivalent sources are obtained by solving an FEM problem over the antenna and its vicinity in conjunction with an absorbing boundary condition (ABC) and/or an impedance boundary condition (IBC). Based on the equivalent sources, the secondary radiation effects arising from mounting structures, e.g. helicopter bodies, are calculated using physical optics (PO) or uniform theory of diffraction (UTD). To show the capability of the hybrid techniques, an antenna on various mounting structures, such as a plate, a cylinder and a helicopter airframe, are investigated. The radiation patterns predicted by the hybrid methods are compared very well with FDTD or measurements showing the validity of the codes.

Anaerobic Accumulation of γ-Aminobutyric Acid and Alanine in Radish Leaves (<i>Raphanus sativus,</i> L.) (1972)

In leaves, the anaerobic accumulation of alanine was accompanied by a loss of aspartate, and these changes preceded gamma-aminobutyrate accumulation and glutamate loss. Changes in keto acid content did not appear to be the cause of amino acid changes. Accumulation of gamma-aminobutyrate was due to acceleration of glutamate decarboxylation and arrest of gamma-aminobutyrate transamination. Changes in enzyme content did not explain the changes in reaction rates in vivo. Most of the aspartate may be converted anaerobically to alanine via oxalacetate and pyruvate.

Pyramids of QTLs enhance host–plant resistance and Bt-mediated resistance to leaf-chewing insects in soybean (2016)

gemmatalis (Hbner)]; and in field-cage assays with SBL. Benning ME+cry1Ac was tested in detached-leaf assays against SBL, VBC, and Southern armyworm [SAW, Spodoptera eridania (Cramer)]. In the detached-leaf assay, Benning ME showed the strongest antibiosis against CEW, FAW, and VBC. In field-cage conditions, Benning ME and Benning MGHE suffered 61 % less defoliation than Benning. Benning ME+cry1Ac was more resistant than Benning ME and Benning cry1Ac against SBL and SAW. Agriculturally relevant levels of resistance in soybean can be achieved with just two loci, QTL-M and QTL-E. ME+cry1Ac could present an opportunity to protect the durability of Bt genes in elite soybean cultivars. These results should assist the development of effective pest management strategies, and sustainable deployment of Bt genes in soybean.
과잉 Si 를 함유한 Al - Mg - Si 합금의 시효거동 (2001)

Aging behavior of Al-Mg-Si alloys with high silicon content was investigated in the present study. Excess silicon leads to unique aging behavior. The Al-Mg-Si alloys show seven exothermic peaks in DSC thermogram. These peaks seem to be induced by the formation of clustering of Si and Mg atoms, G-P zone, unknown small precipitates, β$quot; phase, B` phase, Si particle and β phase. The content of excess Si has no relationship with the precipitation of β$quot; phase and B` phase, but it affected on the formation of Si particles. Natural aging has a distinct influence on the subsequent precipitation process. It is proposed that the formation of stable silicon clusters during natural aging is the major reason for such an effect.

Enhanced Influenza Virus-Like Particle Vaccines Containing the Extracellular Domain of Matrix Protein 2 and a Toll-Like Receptor Ligand (2012)

The extracellular domain of matrix protein 2 (M2e) is conserved among influenza A viruses. The goal of this project is to develop enhanced influenza vaccines with broad protective efficacy using the M2e antigen. We designed a membrane-anchored fusion protein by replacing the hyperimmunogenic region of Salmonella enterica serovar Typhimurium flagellin (FliC) with four repeats of M2e (4.M2e-tFliC) and fusing it to a membrane anchor from influenza virus hemagglutinin (HA). The fusion protein was incorporated into influenza virus M1-based virus-like particles (VLPs). These VLPs retained Toll-like receptor 5 (TLR5) agonist activity comparable to that of soluble FliC. Mice immunized with the VLPs by either intramuscular or intranasal immunization showed high levels of systemic M2-specific antibody responses compared to the responses to soluble 4.M2e protein. High mucosal antibody titers were also induced in intranasally immunized mice. All intranasally immunized mice survived lethal challenges with live virus, while intramuscularly immunized mice showed only partial protection, revealing better protection by the intranasal route. These results indicate that a combination of M2e antigens and TLR ligand adjuvants in VLPs has potential for development of a broadly protective influenza A virus vaccine.
Tests of Glycemia in Diabetes Mellitus (1989)

Major advances in the diagnosis and management of diabetes have been made in the past 10 years. In particular, an array of epidemiologic studies have provided a logical basis for diagnostic standards, and two new means of assessing glycemia--glycated hemoglobin and self-monitoring of blood glucose--have become widely available. These tests allow more convenient approaches to diagnosis, and provide a fuller description of glycemia, permitting more informed and intensive therapy.
CAL: A Generic Query and Analysis Language for Data Warehouses. (2011)

Data warehouses (DWs) and OLAP systems are essential tools in organizational decision making. However, users of these systems are often provided with complex data models and system-specific GUIs and dashboards to analyze the data and generate reports. Available DW query languages like MDX and Oracle OLAP support only numeric data and moreover require skilled DW developers to design queries. This can strain the analyst and restrict effective data analysis. In this paper, we provide a solution to this problem by introducing a powerful textual query language based entirely on the abstract datacube metaphor for multidimensional analysis. This language called the Cube Analysis Language (CAL) captures the full dimensionality of the data while providing an extensible query interface for the analyst. CAL includes three basic components: the Cube Definition Language (CDL), to design and develop the cube, the Cube Manipulation Language (CML), to manipulate and alter the cube, and the Cube Query and Analysis Language (CQAL), to navigate through cubes and aggregate data in the DW for analysis. CDL, CML and CQAL are designed to be explicit user-level concepts that work easily with existing OLAP languages and logical DW designs. To demonstrate its functionality we have implemented the CAL query processor for Mondrian (an open-source OLAP tool) and tested it using an example business sales dataset on Postgres. 1
(Aminoalkoxy)chromones. Selective .sigma. receptor ligands (1992)

A series of (aminoalkoxy)chromones has been prepared, members of which bind potently (16-100 nM) at the sigma binding site and bind weakly (greater than 1000 nM) at the dopamine D2 receptor and 33 other receptors, second messenger systems, and ion channels. At the sigma receptor, the preferred position of attachment for the aminoalkoxy side chain to the chromone ring followed the rank order: 7-position greater than 5-position greater than 6-position. Chromones that contained a 2-substituent that was not coplanar with the chromone ring system showed improved binding over compounds with coplanar substituents. The most potent compound at the sigma site, 7-[[7-(4-hydroxypiperidyl)heptyl]oxy]-2-phenylchromone (74), had receptor affinities (IC50) of 16 nM at the [3H]DTG site, 19 nM at the [3H]-(+)-3-PPP site, and 4000 nM (Ki) at the dopamine D2 receptor. The most selective compound examined, 6-[[6-(4-hydroxypiperidyl)hexyl]-oxy]-2-cyclopentylchromone (58), exhibited IC50s of 51 nM at the [3H]DTG site, 55 nM at the [3H]-(+)-3-PPP site, and 21,000 nM (Ki) at the dopamine D2 receptor. Compound 44 (6-[[6-(4-hydroxypiperidyl)hexyl]oxy]-3-methylflavone, NPC 16377) was systemically effective (ip and po) in two behavioral models predictive of antipsychotic compounds and systemically active in animal models of ischemia.
Prophylactic administration of interleukin-2 protects mice from lethal challenge with gram-negative bacteria (1987)

Prophylactic administration of recombinant human interleukin-2 (IL-2) in mice enhanced survival and produced complete recovery from an otherwise lethal acute bacterial infection. IL-2 was administered as a single intraperitoneal or intravenous bolus dose to CDI mice 18 h before challenge with a lethal dose of a clinical isolate of Escherichia coli type O2 (minimal 100% lethal dose, 6 X 10(7) CFU per mouse). At IL-2 dosages of 7 X 10(6) U/kg, 90% of treated CDI mice survived as compared to 0% for the excipient buffer control animals (P less than 0.001). This protective effect was also demonstrable in immune-deficient beige mice. The IL-2 effect was dose dependent; protection was consistently observed in mice pretreated with IL-2 at doses ranging from 1.8 X 10(6) to 7 X 10(6) U/kg. However, at 3.5 X 10(5) U/kg the protective effect was more variable. The route of administration of IL-2 was shown to play an important role; when IL-2 and challenge bacteria were given by the same route (either intravenously or intraperitoneally), protection was readily observable, but when IL-2 and challenge bacteria were given by different routes, little or no protective effect was observed. The protective effect was fully inducible as early as 1 h after IL-2 administration and was effective against various strains of gram-negative bacteria, indicating that the probable mode of action represents control of the establishment of infection by increased activity of the nonspecific host defense mechanisms. The IL-2 effect was abrogated by the administration of carrageenan, suggesting a possible role of macrophages. These data demonstrate that IL-2 may be a potentially useful adjunct for the prophylaxis of bacterial infections in both clinical and veterinary medicine.
Pt/Ti/<i>p</i>-InGaAsP nonalloyed ohmic contact formed by rapid thermal processing (1989)

Nonalloyed ohmic contacts of Pt/Ti to 5×1018 cm−3 doped p-InGaAsP (λg =1.3 μm) have been fabricated by rapid thermal processing of sputtered and e-gun-deposited metallizations. While the former as-deposited had a rectifying characteristic, the latter showed ohmic behavior prior to any heat treatment, with a specific contact resistance of 4×10−3 Ω cm2. Rapid thermal processing at temperatures higher than 400 °C caused the formation of ohmic contacts for the sputtered metals also, but with the evaporated metals producing slightly lower contact resistance. The lowest specific contact resistance values of 3.6–5.5×10−4 Ω cm2 for evaporated and sputtered metallizations, respectively, were achieved in both cases as a result of heating at 450 °C for 30 s. These heating conditions produced only a limited reaction at the Ti/InGaAsP interface, which was sharper for the e-gun-deposited contact, but had a significant effect on the stresses in the Ti/Pt bilayer. In both the sputtered and electron gun evaporated samples, the stresses were inverted from tensile as-deposited to compressive with values of 2.4×109 and 1.0×109 dyn cm−2, respectively, as a result of the heat treatment.
