Migration decision for hybrid mobility in reconfigurable distributed virtual machines (2004)

Virtual machine (VM) is an important mechanism to multiplex computer resources. The increasing popularity of network computing has renewed research interests in the adaptive and distributed virtual machines. Service migration is a vital technique to construct reconfigurable VMs. By incorporating mobile agent technology, VM systems can improve their resource utilization, load-balancing and fault-tolerance significantly. This work focuses on the decision problem of hybrid mobility for load-balancing in reconfigurable distributed VMs. We tackle this problem from three aspects: migration candidate determination, migration timing and destination server selection. The service migration timing and destination server selection are formulated as two optimization models. We derive the optimal migration policy for distributed and heterogeneous systems based on stochastic optimization theories. Renewal processes are applied to model the dynamics of migration. We solve the agent migration problem by dynamic programming and extend the optimal service migration decision by considering the interplay of the hybrid mobility. Our decision policy is complementary to the existing service and agent migration techniques. Its accuracy is verified by simulations.

A sparsity-driven joint image registration and change detection technique for SAR imagery (2010)

This paper presents a novel Sparsity-driven joint Image REgistration and Change Detection (SIRE-CD) technique for SAR imagery. The proposed algorithm simultaneously performs two main tasks: (i) locally register the test and reference images; and (ii) perform the change detection between the two. The key innovative concept here is the sparsity-driven transformation of the signatures from the reference image to match to those of the test image at the local image patch level. In other words, we are constructing a large dictionary from the reference data and use that to find the sparsest representation that best approximates the new incoming test data. The accuracy level of the approximation determines the detected changes between the reference and the test image. We demonstrate the performance of this technique using both simulated data and real SAR imagery from the Army Research Laboratory ultra-wideband (UWB) SAR forward-looking radar.
Using marker-aided selection to improve tree growth response to abiotic stress (1992)

The ability to locate quantitative trait loci (QTL) on a restriction fragment length polymorphism (RFLP) genetic linkage map will provide tree breeders the means to overcome some currently intractable problems inherent to breeding long-lived tree species. These RFLP–QTL maps will allow early, indirect, marker-aided selection (MAS) in breeding programs. This paper explores the opportunities and limitations of MAS, an approach to developing an RFLP–QTL marker map, and use of the map in breeding loblolly pine (Pinustaeda L.) for improved growth response to abiotic stress; specifically, drought stress. Growth responses under moderate drought stress are important to long-term forest productivity, because on most sites loblolly pine is subjected to growth-limiting moisture stress during part of almost every growing season. MAS provides new precision and reliability in identifying and breeding trees that are able to continue growth under moderate stress, and perhaps provides a unique opportunity for improving tree productivity on moderately stressful sites. Traits potentially related to growth under stress are identified, and their suitability for placement and use on an RFLP–QTL linkage map is discussed.
A Microwave System for Measurement of the Diameter of Thin Dielectric Fibers (1974)

An active microwave system for continuous and contactless measurement of the diameter or basic weight of a low-loss continuous dielectric fiber is described. The frequency of oscillation of a Gunn-diode oscillator is a measure of the diameter of the dielectric fiber passing through the oscillator cavity. Some experimental results are presented and limitations of the method discussed.
Changes in knee kinematics after application of an articulated external fixator in normal and posterior cruciate ligament‐deficient knees (1997)

We studied how the location of an articulated external fixator, the EBI-Orthofix (EBI Corp, Persippany, NJ), affects the kinematics of the posterior cruciate ligament (PCL)-deficient knee. Ten unembalmed cadaver whole lower limbs were randomly divided into two groups of five limbs each: (1) fixator hinge located near the average knee flexion axis (the anatomic position group); and (2) fixator hinge located distal to the joint line and posterior to the flexion axis (the fibular styloid position group). Three loading conditions, passive flexion/extension, flexion/extension with anterior force of 100 N, and flexion/extension with posterior force of 100 N were used for each knee with the PCL intact and with the PCL cut. With the fixator located in the anatomic position, and after cutting of the PCL, posterior translation was reduced to normal limits only at flexion angles < or = 15 degrees. In this configuration, the fixator was ineffective at minimizing posterior translation at flexion angles > or = 30 degrees. With the fixator located at the fibular styloid position, however, posterior translation of the tibia in the PCL deficient knees was reduced to near normal limits at all flexion angles. These results were statistically different than the anatomic position group at all flexion angles > or = 30 degrees (P < .01). The external fixator appears to allow normal range of motion while effectively shielding the PCL graft from stress caused by posterior translational forces. Issues related to the potential complications and patient acceptance must be addressed thoroughly before this technique is applied in clinical practice.
Binaural Summation of the Acoustic Reflex (1996)

Although the presence of a contralateral component elicits a summation or facilitation effect, the particular intensity value contributes little to the magnitude of that effect.
A priori test coverage estimation for automated production systems: Using generated behavior models for coverage calculation (2017)

Automated production systems need to be thoroughly tested. For this, the fully integrated system, consisting of software and hardware, is investigated for remaining bugs using system tests. Unlike unit tests, these tests involve human interaction with the system and are mostly performed manually, without any tool support for their simulation or adequacy examination. Thus, important functionality can be overlooked during testing, decreasing the overall system quality. Coverage measurement during testing can be a valuable support for assessing test adequacy, but requires instrumentation that might influence the real time behavior of the system. Further, test adequacy cannot be calculated until all tests have been executed. To tackle these problems, we propose an approach that aims at estimating coverage criteria prior to system test execution at the aPS and without instrumenting the code or defining hardware simulations. To this end, the nominal hardware behavior and human interaction models are derived from existing integration tests, enabling a priori estimation of the system test coverage via simulation of the software along with the deduced behavior.
Crowdsourced Data Management: A Survey (2017)

Many important data management and analytics tasks cannot be completely addressed by automated processes. These tasks, such as entity resolution, sentiment analysis, and image recognition can be enhanced through the use of human cognitive ability. Crowdsouring is an effective way to harness the capabilities of people (i.e., the crowd) to apply human computation for such tasks. Thus, crowdsourced data management has become an area of increasing interest in research and industry. We identify three important problems in crowdsourced data management. (1) Quality Control: Workers may return noisy or incorrect results so effective techniques are required to achieve high quality, (2) Cost Control: The crowd is not free, and cost control aims to reduce the monetary cost, (3) Latency Control: The human workers can be slow, particularly compared to automated computing time scales, so latency-control techniques are required. There has been significant work addressing these three factors for designing crowdsourced tasks, developing crowdsourced data manipulation operators, and optimizing plans consisting of multiple operators. We survey and synthesize a wide spectrum of existing studies on crowdsourced data management.
Formation of Lead Zirconate‐Lead Titanate Solid Solutions (1965)

Formation of the Pb(Zr,Ti)O 3 solid solution in the system PbO‐TiO 2 ‐ZrO 2 was studied by chemical analysis and X‐ray powder diffrac‐tometry. Only PbTiO 3 and Pb(Zr,Ti)O 3 were found as reaction products. The following three elementary reactions seemed to be reasonable for the formation of the Pb(Zr,Ti)O 3 phase: PbO + TiO 2 → PbTiO 3 , PbTiO 3 + PbO + ZrO 2 →Pb(Zr 1‐λ Ti λ )O 3 , and Pb(Zr l‐λ Ti λ )O 3 + PbTiO 3 → Pb(Zr 1‐λ′ Ti λ′ )O 3 (λ<λ′).
Effect of rapid thermal annealing on the electrical and physical properties of metalorganic chemical-vapor-deposited TiN (1996)

This work reports on the effect of postdeposition thermal treatment using rapid thermal annealing on the physical and electrical properties of metalorganic chemical-vapor-deposited (MOCVD) titanium nitride (TiN) thin films. When ammonia is used as the annealing ambient, the resistivity decreases with increasing annealing temperature. The resistivity of MOCVD TiN was reduced from 6000 to 320 μΩ cm after 800 °C rapid thermal annealing in ammonia (RTN). Annealing in nitrogen ambient was found to be not nearly as effective as that in ammonia. The decrease in resistivity may be attributed to a reduction in the carbon and oxygen content, growth in grain size through polycrystalline recrystallization, as well as to an increase in film density.
Triacylglycerol lipases and metabolic control: implications for health and disease (2010)

Fatty acids derived from the hydrolysis of adipose tissue and skeletal muscle triacylglycerol (TG) are an important energy substrate at rest and during physical activity. This review outlines the identification of the new TG lipase, adipose triglyceride lipase, the current understanding of how cellular TG lipases are regulated, and the implications for understanding the integrated control of TG lipolysis. Furthermore, this review outlines recent advances that propose a "revised" role for TG lipases in cellular function, metabolic homeostasis, and disease prevention.
A three-branched DNA template for carbon nanotubeself-assembly into nanodevice configuration (2008)

The third gamma subunit of the gamma-aminobutyric acid type A receptor family. (1992)

Cloned cDNAs encoding a member of the gamma-aminobutyric acid type A receptor gamma-subunit class were isolated from rat-brain-mRNA-derived libraries. The gamma 3 mRNA is present in cortex, claustrum, caudate putamen, and some thalamic nuclei, particularly the medial geniculate nucleus, where it is the predominant gamma-subunit transcript. The gamma 3 gene is expressed at very low levels in cerebellum and hippocampus. In coexpression experiments with the alpha 1 and beta 2 subunits, gamma 3 imparts benzodiazepine binding to gamma-aminobutyric acid type A receptors and forms gamma-aminobutyric acid-gated benzodiazepine-modulated chloride channels that exhibit a larger conductance than alpha 1 beta 2 receptor channels. Furthermore, the presence of gamma 3 in place of gamma 2 in alpha 1 beta 2 gamma x receptors generates a marked decrease in the affinity of agonists while leaving the affinity of antagonists or negative modulators largely unaffected.
Exploring Temporal Frameworks for Constructing Longitudinal Instance-Specific Models from Clinical Data (2012)

The prevalence of the EMR in biomedical research is growing, the EMR being regarded as a source of contextually rich, longitudinal data for computation and statistical/trend analysis. However, models trained with data abstracted from the EMR often (1) do not capture all features needed to accurately predict the patient's future state and to ground clinical decisions; and (2) are not normalized to a standardized timeline. This dissertation demonstrates the advantages of instance-specific predictive models and event-based frameworks for normalizing population and patient-specific data, by evaluating a modified Lazy Bayes' Rule algorithm adapted to structured and unstructured longitudinal clinical datasets. The results of the evaluations indicate the superior performance of the instance-specific model over its global equivalents, in the context of staging clinical data via event-based change.
The routing protocol of AODV based on link failure prediction (2008)

In large-scale Ad Hoc networks, the frequent interrupting of networks can produce prodigious transmission delay, and also can reduce the packet delivery rate, in view of such disadvantages, this paper introduces the mechanism of link failure prediction into the AODV routing protocol in the process of data transmission, and simulates the improved AODV routing protocol through NS-2, the test results indicate that the improved routing protocol AODV_LFF can reduce the network transmission delay effectively, and also can boost the packet delivery rate.
Effects of a Single Height Gene (<i>DW</i>3 of Sorghum on Certain Agronomic Characters<sup>1</sup> (1975)

Results of a study, to determine more closely the degree of dominance of the Dw a gene of sorghum [ Sorghum bicolor (L.) Moench] and to investigate further the relationships between height and other agronomic traits, are reported. Isogenic lines of ‘Martin,’ ‘Plainsman,’‘Redlan,’ and ‘Tx403,’ homozygous for the dominant and recessive allele of Dw s were compared with heterozygous lines produced from crosses of each short line to its tall counterpart. Data were collected and analyzed for culm height, grain yield, test weight, kernel weight, panicles/plant, peduncle length, and node number. Height genotype influenced total yield, test weight, panicles/plant, and kernel weight, as well as culm height. Cultivar ✕ height interactions were observed for height, test weight, and kernel weight. Height appeared to be partially dominant. The degree of dominance recorded for Martin, Plainsman, and Redlan was 0.70, 0.70, and 0.82, respectively. Yields of the heterozygous lines were not significantly different from those of the corresponding homozygous tall lines. In general, heterozygous lines had test weights and kernel weights equal to those of the tall homozygous fines and higher than those of the short parents. Heterozygous lines tended to have more panicles/plant than did either the tall or short lines.
Protective efficacy, immunotherapeutic potential, and safety of hepatitis B vaccines (2005)

Hepatitis B vaccines are highly effective and safe and have been incorporated into national immunization programs in over 150 countries. The major humoral immune response is to the common a determinant of the surface antigen protein of the virus. Approximately 5-10% of healthy immunocompetent subjects do not mount an antibody response (anti-HBs). Non-response is associated with different HLA-DR alleles and impaired Th cell response, among other factors such as route of injection, age, gender, body mass, and other factors. Important hepatitis B surface antigen variants have also been identified, which may have a potential impact on immunization and routine screening of blood, blood products and tissues, and organs for transplantation. Strategies for hepatitis B immunization are reviewed. Over 1,000 million doses of hepatitis B vaccine have been used with an outstanding record of safety. There is no evidence of an association between hepatitis B vaccines and the sudden infant death syndrome, chronic fatigue syndrome, and multiple sclerosis (MS). Several studies are in progress on treatment of chronic hepatitis B infection by immunization with multiple antigenic components, combination of vaccine with antiviral drugs and cytokines, T cell vaccines, DNA vaccines alone or with DNA encoded immunomodulatory cytokines, and direct genetic manipulation of antigen presenting cells.
On analytical modeling and design of a novel transverse flux generator for offshore wind turbines (2007)

The object of this thesis is to develop a cost effective direct-driven wind generator suited for offshore wind turbines. As the generator price is a complicated function dependent on many parameters, the emphasis is mainly put on reduction of the weight of active materials, such as copper, laminated steel, permanent magnets, and electrical insulation. The higher specific torque and power density of a transverse flux permanent magnet (TFPM) machine in comparison to conventional radial-flux machines make it a promising solution for direct-driven wind turbine generators. The novel TFPM generator investigated in this work due to its possibly more compact construction would allow a better utilization of the available nacelle space. The analytical model, including evaluation of the synchronous inductance, is developed and applied in parametric study of a 5 MW wind turbine generator. The influence of the design variables with respect to the analyzed characteristics is investigated. A number of machines that have approximately the same performances are found. These machines are compared and the optimal ranges for the main parameters are suggested. One possible design topology is presented in more details with dimensions and main characteristics. This generator is compared with radial-flux generators with surface-mounted and tangentially-polarized magnets. It is found that the analyzed TFPM generator would favor a smaller outer diameter, reduced total active weight, and reduced weight of the magnet material. The TFPM would however require a longer axial length. TFPM generators with a broader range of output power have also been investigated. Generators rated 3, 5, 7, 10, and 12 MW are analyzed and their characteristics with respect to the output power are compared. The novel transverse flux topology has been found to be promising for low-speed hightorque applications, such as direct-driven wind turbines in the multi-megawatt range.
Outgassing Caused by Electron Bombardment of Glass (1960)

A flow system used for continuous measurement of the gases evolved from aluminized glass during bombardment with 20 kev electrons is described. The system is also suitable for gettering measurements. A cathode-ray tube containing the samples is sealed directly to the source of a mass spectrometer. Calibration of the first flow system built revealed the gettering of oxygen by the graphite-silicate conductive coating and the hot metal parts of the electron gun of the cathode-ray tube. This gettering was minimized in a second flow system. It was found that oxygen constitutes at least 95% of the gas evolved from each of five types of glasses investigated. Also, a graphite-silicate coating can play a dual role in a cathode-ray tube; when not bombarded by electrons it is an active getter for oxygen, but when bombarded it is a source of oxygen, carbon monoxide, and carbon dioxide.
Fundamental Aspects of Polymer Degradation By High-Energy Radiation (1985)

Understanding of the mechanism of radiation degradation of polymer molecules is essential for development of improved and new industrial processes, for radiation-induced modification of polymer properties, and for selection of polymers for use in radiation environments. This means that the detailed chemical reactions resulting from absorption of radiation must be known. This fundamental understanding must enable us to relate the chemical structure of a polymer to changes in its chemical, physical and material properties. Such structure-property relationships require a great deal of research work, but they are the key to further advancement on a scientific basis. The morphology of solid polymers is also an important parameter. Thus, radiation-induced changes can be expected to differ in crystalline and amorphous regions — but in what way and to what extent? "Crystallinity" and "amorphous" are not absolute terms and as more becomes known about the solid-state structure of polymers this should be related
Measurement of nuclear size distribution of epithelial tissues in vivo for diagnosis of early precancerous changes using reflectance spectroscopy (1998)

Summary form only received as follows: The author observed a fine component in backscattered light from mucosal tissue, which is periodic in wavelength. This structure is ordinarily masked by a diffusive background. The author has identified the origin of this component as being due to light that is Mie scattered by surface epithelial cell nuclei. By analyzing the amplitude and frequency of the fine structure, the density and size distribution of these nuclei can be extracted. In an in vivo clinical study in patients with Barrett's esophagus, a spectroscopic diagnosis was made and then compared to the histologic diagnosis. In vivo spectroscopy was both sensitive and specific for the diagnosis of early precancerous changes.
Electrodeposition and compositional behaviour of Zn-Ni alloy (2007)

This paper discusses the optimization of an electroplating bath for smooth and uniform deposition of zinc-nickel alloy on mild steel. Electroplating has been carried out in a chloride bath using glycine and gelatin as additives. The effect of bath conditions and operating parameters on chemical composition, micro-hardness and appearance of the deposit have been studied and discussed. The experimental results reveal that a bright Zn-Ni alloy having about 13.6 %Ni is showing good performance against corrosion. The corrosion resistance of the deposit is found to be characteristic of its %Ni content, and is improved drastically after chrome passivation. The bath follows anomalous codeposition with preferential deposition of Zn over the entire current density range used for the study. The increase of %Ni in the deposit with current density is due to the depletion of more readily depositable Zn 2+ ions at the cathode. No transition current density, at which the codeposition behaviour changed from the anomalous to normal type, was observed during the study. The increase of %Ni in the deposit at high current density (c.d.) is attributed to high ratio of Ni 2+ /Zn 2+ in the bath. The effect of temperature on the plating process showed that codeposition of metals on the cathode is diffusion controlled.
