Switched-capacitor converters with multiphase interleaving control (2011)

This paper proposes a configuration of switched-capacitor converters with multiphase interleaving control that can perform conventional switched-capacitor voltage conversions with little electromagnetic interference over a wide range of operating condition. This is achieved by having multiple units of switched-capacitor converter connected in parallel and a unit selection control scheme which works along the interleaving control to vary the number of converters in operation. By having the capacitors of inactive units connected to the output and the converters operating with output interleaving operation, the output capacitor that is typically required in switched-capacitor converters for maintaining a small voltage ripple is made redundant in this configuration.
<i>Caf1R</i> gene and its role in the regulation of capsule formation of <i>Y. pestis</i> (1992)

A new transcription unit of the f1 gene cluster was found. The DNA sequencing revealed one long open reading frame. Deletion and frame shift mutation analyses have demonstrated the importance of a corresponding gene product for the F1 antigen biosynthesis. A homology of the deduced amino acid sequence with that of AraC family DNA-binding regulators was shown. A potential regulatory DNA region is discussed.
Combined instruction and loop parallelism in array synthesis for FPGAs (2001)

Compiling perfect, uniform dependence loops to fpga based co-processors normally yields processor pe arrays where a pe executes one instance of the loop body per clock cycle. We develop a transformation framework in which the derived pe can be systematically and automatically pipelined through retiming. We use well known transformations-skewing and serialization, by which an arbitrary number of registers may be placed at the pe outputs. They are then moved into the pe data-path using standard commerecial circuit retimers. Our experiments (based on performance estimates after place-and-route) have been very encouraging. For a number of examples we have seen dramatic performance improvements: speed increases of an order of magnitude with relatively little (always less than 100%) area overhead.
Pleckstrin homology domains: not just for phosphoinositides (2004)

PH domains (pleckstrin homology domains) are the 11th most common domain in the human genome and are best known for their ability to target cellular membranes by binding specifically to phosphoinositides. Recent studies in yeast have shown that, in fact, this is a property of only a small fraction of the known PH domains. Most PH domains are not capable of independent membrane targeting, and those capable of doing so (approx. 33%) appear, most often, to require both phosphoinositide and non-phosphoinositide determinants for their subcellular localization. Several recent studies have suggested that small GTPases such as ARF family proteins play a role in defining PH domain localization. Some others have described a signalling role for PH domains in regulating small GTPases, although phosphoinositides may also play a role. These findings herald a change in our perspective of PH domain function, which will be significantly more diverse than previously supposed.
Amylose Determination of Native High‐Amylose Corn Starches by Differential Scanning Calorimetry (2005)

Abstract Differential scanning calorimetry (DSC) was investigated as an alternative method to more conventional iodine‐binding methods for determining starch amylose in a maize breeding program, because it requires fewer steps. In addition, many current DSC instruments are now equipped with sampling robots for performing automated analysis. The iodine‐binding method and a recently described DSC method for amylose determination were compared using five commercial starch samples. In addition, two sets (Set 1 and Set 2) of germplasm samples obtained from a high‐amylose breeding program were examined using each method. Correlation coefficients ( r 2 ) between the two methods for the commercial starch samples, Set 1 and Set 2 were found to be 0.99, 0.89 and 0.82, respectively, suggesting a good correlation but with greater discrepancy between them with increasingly higher amylose values. The DSC method appeared to have an improved repeatability, because its associated CV value was lower (4.1%) compared to the iodine‐binding method (5.8%). It was concluded that the DSC method should be effective in discriminating high‐amylose genotypes in a breeding program specifically designed to identify maize starches with amylose values at or above 70%.
Improved Performance of Plasmonic Thermal Emitter via Incorporation of Gold Nanoparticles (2013)

The improved performance of plasmonic thermal emitter by incorporating randomly distributed gold nanoparticles is demonstrated in the mid-infrared range. Gold films with different thicknesses were deposited on top of the devices and then annealed to form separate nanoparticles. Experimental results showed that the size and distribution of nanoparticles depend mainly on the gold film thickness, rather than annealing temperature. It is observed that thermal emitters with smaller particles embedded exhibit significant enhancement in emission intensity. It is the strong scattering between gold nanoparticles that contributes to the enhanced infrared thermal emission. As an efficient mid-infrared radiation source, this device has the potential to be applied in various fields such as second harmonic generation of infrared source and biosensors.
Response to interferon therapy: influence of human leucocyte antigen alleles in patients with chronic hepatitis C (1998)

The response to interferon (IFN) therapy in patients with chronic hepatitis C is characterized by normalization of the serum alanine aminotransferase (ALT) activity during treatment, but relapse within 6 months of cessation of therapy is common. Viral characteristics, such as the genotype and viral load, may influence the patient response to IFN. The aim of this study was to examine host factors, namely the genetically determined human leucocyte antigen (HLA) class II alleles, in patients with chronic hepatitis C, and their relationship to the response to IFN therapy. Seventy white patients with chronic hepatitis C, treated with IFN-alpha for 6 months, were enrolled in the study. Serum ALT was measured at the end of treatment to assess short-term response and again 6 months post-treatment to assess sustained response. Sequence-specific primers were used in the polymerase chain reaction (PCR) to amplify genomic DNA isolated from peripheral mononuclear cells. HLA class II alleles were determined by analysis of the amplicon by gel electrophoresis and hybridization of sequence-specific oligonucleotide probes. At the end of treatment, 25 of the 70 patients (36%) had a normal ALT. By 6 months post-treatment, only six patients (9%) had a sustained normalization of ALT. The frequency of the allele DRB1*0404 was significantly higher in patients with a sustained response as compared to those lacking such a response (25.0% vs 2.3%, with a Bonferonni-corrected P-value of 0.019). There was no difference in the frequency of other class II alleles at the DRB1 and DQB1 loci in responders as compared with non-responders. Therefore, we conclude that the maintenance of a response to IFN in chronic hepatitis C may be, in part, determined by genetic factors in the host.
The effect of textual variation on concept based information retrieval. (1996)

Accounting for textual variation in the documents and queries processed by information retrieval systems is considered essential for achieving good retrieval. Recent research has called into question several of the techniques used to support this endeavor. This paper reports on experiments with a concept based information retrieval system which relies on a program called MetaMap to account for textual variation in the process of mapping biomedical text such as MEDLINE bibliographic citations to the UMLS Metathesaurus. The experiments confirm that the effort expended in handling textual variation is well-spent for at least one type of concept based information retrieval.
Controlled Synchronization of Heterogeneous Robotic Manipulators in the Task Space (2011)

Passivity-based control has emerged as an important paradigm for synchronization of networked robotic systems. Despite the practical utility of task-space algorithms, the previous results focused on joint-space synchronization and were primarily derived for kinematically identical manipulators. Hence, in this paper, the problem of task-space synchronization of (possibly redundant) heterogeneous robotic systems is studied. By exploiting passivity-based synchronization results that are developed previously, an adaptive control algorithm is proposed to guarantee task-space synchronization of networked robotic manipulators in the presence of dynamic uncertainties and time-varying communication delays. To demonstrate the efficacy of the proposed framework, numerical simulations and experiments are conducted with redundant and nonredundant manipulators, respectively.
Improved Combinatorial Programming Algorithms for a Class of All-Zero-One Integer Programming Problems (1973)

In an earlier paper [Pierce, J. F. 1968. Application of combinatorial programming to a class of all-zero-one integer programming problems. Management Sci. 15 (3, November) 191–209.] combinatorial programming procedures were presented for solving a class of integer programming problems in which all elements are zero or one. By representing the problem elements in a binary computer as bits in a word and employing logical “and” and “or” operations in the problem-solving process, a number of problems involving several hundred integer variables were solved in a matter of seconds. In the present paper a number of improvements in these earlier algorithms are presented, including a new search strategy, methods for reducing the original problem, and mechanisms for feasibility filtering in multi-word problems. With these improvements problem-solving efficiency has been increased in many instances by an order of magnitude. In addition, the present paper contains computational experience obtained in solving problems for the k-best solutions.

Illustration2Vec (2015)

Referring to existing illustrations helps novice drawers to realize their ideas. To find such helpful references from a large image collection, we first build a semantic vector representation of illustrations by training convolutional neural networks. As the proposed vector space correctly reflects the semantic meanings of illustrations, users can efficiently search for references with similar attributes. Besides the search with a single query, a semantic morphing algorithm that searches the intermediate illustrations that gradually connect two queries is proposed. Several experiments were conducted to demonstrate the effectiveness of our methods.
Hierarchical Game-Theoretic Planning for Autonomous Vehicles (2019)

The actions of an autonomous vehicle on the road affect and are affected by those of other drivers, whether overtaking, negotiating a merge, or avoiding an accident. This mutual dependence, best captured by dynamic game theory, creates a strong coupling between the vehicle's planning and its predictions of other drivers' behavior, and constitutes an open problem with direct implications on the safety and viability of autonomous driving technology. Unfortunately, dynamic games are too computationally demanding to meet the real-time constraints of autonomous driving in its continuous state and action space. In this paper, we introduce a novel game-theoretic trajectory planning algorithm for autonomous driving, that enables real-time performance by hierarchically decomposing the underlying dynamic game into a long-horizon “strategic” game with simplified dynamics and full information structure, and a short-horizon “tactical” game with full dynamics and a simplified information structure. The value of the strategic game is used to guide the tactical planning, implicitly extending the planning horizon, pushing the local trajectory optimization closer to global solutions, and, most importantly, quantitatively accounting for the autonomous vehicle and the human driver's ability and incentives to influence each other. In addition, our approach admits non-deterministic models of human decision-making, rather than relying on perfectly rational predictions. Our results showcase richer, safer, and more effective autonomous behavior in comparison to existing techniques.
A tree convolution algorithm for the solution of queueing networks (1983)

A new algorithm called the tree convolution algorithm, for the computation of normalization constants and performance measures of product-form queueing networks, is presented. Compared to existing algorithms, the algorithm is very efficient in the solution of networks with many service centers and many sparse routing chains. (A network is said to have sparse routing chains if the chains visit, on the average, only a small fraction of all centers in the network.) In such a network, substantial time and space savings can be achieved by exploiting the network's routing information. The time and space reductions are made possible by two features of the algorithm: (1) the sequence of array convolutions to compute a normalization constant is determined according to the traversal of a tree; (2) the convolutions are performed between arrays that are smaller than arrays used by existing algorithms. The routing information of a given network is used to configure the tree to reduce the algorithm's time and space requirements; some effective heuristics for optimization are described. An exact solution of a communication network model with 64 queues and 32 routing chains is illustrated.
The role of integrin receptors in aspects of glioma invasion <i>in vitro</i> (1999)

Integrins are heterodimers consisting of non-covalently associated alpha and beta subunits. They mediate adherence of normal and tumour cells to the extracellular matrix, a property which is essential for migration of neoplastic astrocytes as they invade into the normal brain parenchyma. Flow cytometry and immunocytochemical analysis of cultured cells derived from 10 gliomas (1 pilocytic astrocytoma, 1 astrocytoma, 1 oligoastrocytoma, 1 anaplastic oligoastrocytoma, 4 anaplastic astrocytomas and 2 glioblastoma multiforme) revealed that the beta1 integrin subunit was generally expressed more strongly than alpha4 or alpha(v) integrin subunits. Subsequent studies with function-blocking antibodies against the beta1 subunit inhibited adhesion, motility and invasion of the gliomas in vitro, to varying degrees, on all extracellular matrix substrates investigated (laminin, collagen type IV, fibronectin and vitronectin), the inhibition by beta1 subunit was greatest on collagen type IV. These studies therefore substantiate the case for a role of the beta1 integrin subunit in neoplastic glial cell invasion of the brain.

Research on Bearing Current Detection Method of High-speed Motor Driven by PWM Inverter (2019)

With the wide application of PWM inverter, bearing failure caused by bearing current seriously affects the reliability and safety of the driving system. Accurate measurement of bearing current is the key to evaluate the simplified model of bearing current and analyze the influence of bearing current. This paper adapts a method for measuring bearing current. Firstly, this paper analyzes the capacitance model of high-speed motor bearings represented by PMSM. Secondly, this paper analyzes and calculates the stray capacitance, and performs finite element calculation for a certain machine. Comparing the analysis results, a method for detecting the shaft current is described. Finally, experimental tests for stray capacitance will be given, the measured stray capacitance value is substituted into the MATLAB simulation model. Based on the proposed detection method, the shaft current waveform is measured to verify the accuracy.
Alkali-Silica Reactivity Resistance of High-Volume Fly Ash Cementitious Systems (2002)

The role of high-volume ASTM Class F fly ash (58% by mass of cement) in reducing expansion caused by alkali-silica reaction was investigated. A series of modified ASTM C1260 tests were performed with three different concentrations of NaOH solution and over an extended test period of 28 days; a reactive siliceous fine aggregate was used. Test results confirm that replacing 58% of portland cement (by mass) with high-volume fly ash in a cementitious system significantly helps control expansion caused by alkali-silica reaction.
DNA topoisomerase inhibitors block erythropoiesis and delay hemoglobinization in vitro (1989)

To examine the importance of topological constraints on DNA during erythroid development, we measured the effects of camptothecin and teniposide, two tumoricidal agents which are also specific inhibitors of type I and type II topoisomerases respectively, on the formation of hematopoietic colonies by cultured human bone marrow cells. When added to bone marrow culture, each inhibitor alone impairs the formation of early BFU-E-derived colonies, late CFU-E-derived colonies and mixed hematopoietic (CFU-GEMM-derived) colonies by up to 100%. Inhibition of colony formation is directly related to the time of inhibitor addition and the inhibitor concentration tested. Although either inhibitor alone reduces colony formation by 90%, when added together at a submaximal concentration, camptothecin and teniposide exert a synergistic suppressive effect. Furthermore, addition of topoisomerase inhibitors to culture impairs hemoglobinization of colony erythroblasts in a time-dependent fashion. In contrast to the effects of topoisomerase inhibitors, the antiproliferative agent aphidicolin reduces erythroid colony number and size without altering hemoglobinization of colony erythroblasts. Since neither topoisomerase inhibitor alters the morphology of cultured cells, the capacity of cells to exclude trypan blue or the potential to form erythroid colonies through the interval required for the first progenitor cell division, it is unlikely that camptothecin or teniposide are cytotoxic to hematopoietic cells. Human mononuclear cells enriched in bone marrow lymphocytes and nucleated erythroblasts from both human and mouse sources release DNA into the detergent soluble fraction. Release requires functional topoisomerases and is altered by acute exposure to topoisomerase inhibitors. Our results suggest that topoisomerases are critical not only to proliferation but also to differentiation of human marrow erythroid progenitor cells and stem cells in culture.
Wideband tunable mm-wave Gunn oscillator design (1981)

A new method of design of mm-wave Gunn oscillators has been developed and tested. The method utilises the fact that high frequency GaAs Gunn diodes work in the harmonic mode for transmission whilst allowing tuning at the fundamental. Hardware for wide frequency coverage (30 GHz centred at about 85 GHz) is described with experimental results.
BitWhisper: Covert Signaling Channel between Air-Gapped Computers Using Thermal Manipulations (2015)

It has been assumed that the physical separation ('air-gap') of computers provides a reliable level of security, such that should two adjacent computers become compromised, the covert exchange of data between them would be impossible. In this paper, we demonstrate BitWhisper, a method of bridging the air-gap between adjacent compromised computers by using their heat emissions and built-in thermal sensors to create a covert communication channel. Our method is unique in two respects: it supports bidirectional communication, and it requires no additional dedicated peripheral hardware. We provide experimental results based on the implementation of the Bit-Whisper prototype, and examine the channel's properties and limitations. Our experiments included different layouts, with computers positioned at varying distances from one another, and several sensor types and CPU configurations (e.g., Virtual Machines). We also discuss signal modulation and communication protocols, showing how BitWhisper can be used for the exchange of data between two computers in a close proximity (positioned 0-40 cm apart) at an effective rate of 1-8 bits per hour, a rate which makes it possible to infiltrate brief commands and exfiltrate small amount of data (e.g., passwords) over the covert channel.
Mapping of index of refraction profile for polymer gradient index optics using confocal Raman spectroscopy (2020)

Scanning confocal Raman microscopy is proposed to measure a gradient index (GRIN) profile at an optical surface. The Raman microscope is calibrated to index of refraction for a binary copolymer GRIN material, and then the index of refraction is mapped on the plano surface of a GRIN polymer lens. The measurement deduces axial shift of 680 μm and identifies lateral tilt or decenter with respect to the nominal position of the GRIN profile. Results suggest that the mapping method is a nondestructive way to measure the GRIN profile of a GRIN lens and its positioning within the lens geometry, to within the sampling precision of the Raman microscope.
