Channel assignment using genetic algorithm based on geometric symmetry (2003)

The paper deals with the channel assignment problem in a hexagonal cellular network with two-band buffering, where channel interference does not extend beyond two cells. Here, for cellular networks with homogeneous demands, we find some lower bounds on the minimum bandwidth required for various relative values of s/sub 0/, s/sub 1/, and s/sub 2/, the minimum frequency separations to avoid interference for calls in the same cell, or in cells at distances of one and two, respectively. We then present an algorithm for solving the channel assignment problem in its general form using the elitist model of genetic algorithm (EGA). We next apply this technique to the special case of hexagonal cellular networks with two-band buffering. For homogeneous demands, we apply EGA for assigning channels to a small subset of nodes and then extend it for the entire cellular network, which ensures faster convergence. Moreover, we show that our approach is also applicable to cases of nonhomogeneous demands. Application of our proposed methodology to well-known benchmark problems generates optimal results within a reasonable computing time.
<title>Scanned bi-orthogonal radiographs as a source for 3D cephalometric data</title> (1996)

We have developed a visualization environment, CEPH, for the analysis of plain film, biothogonally registered, head x-rays, i.e., cephalograms. Most importantly this program facilitates the collection of 3D landmark data from biorthogonal cephalogram pairs, i.e., correlated frontal and lateral images. To this end we have implemented tools for: contrast enhancement, image compression, morphological feature extraction, and grayscale shape recognition for automatic landmark detection. These data are useful for clinical craniofacial: (1) diagnosis, (2) treatment planning, (3) computed-assisted surgery, and (4) post-procedure follow-up. We are currently using the CEPH visualization environment to produce average landmark sets from the nearly 2000 'Bolton Standards' images. These images were collected for the Bolton-Brush Growth Study at Case Western Reserve University. Two dimensional landmark data captured from these images are universally recognized and used as diagnostic and treatment 'norms.' We are planning to make new three dimensional Bolton Standards data available this year. To this end we have scanned all of the Bolton Standards cephalograms at 2400 by 2400 resolution with 12 bits of grayscale information on a TDI scanner.
GTO thyristors (1988)

Major aspects of gate-turn-off (GTO) thyristors are discussed, including device modeling, design considerations, basic research on their switching phenomena, electrical characteristics, and applications. A device design is considered which would increase the maximum interruptible anode current I/sub ATO/ and blocking voltage while decreasing the switching time and power dissipation. The most difficult design problem is to determine the dominant factors that affect I/sub ATO/. From experimental and computational results, it is found that I/sub ATO/ is increased by a reduced p-base sheet resistance, a thicker n-base layer and an increased gate-cathode breakdown voltage. The turn-off performance is also improved by introducing several modified device structures, such as an anode-shorted emitter construction, an asymmetric n/sup +/-doped based structure, a buried gate, and a cathode emitter heterojunction GTO thyristor. Typical characteristics are given for a 5000-V 3000-A unit. GTO applications are discussed, including variable-voltage variable-frequency inverter-controlled AC induction motor drive systems and PWM converter systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Neurogenesis Deep Learning (2016)

Neural machine learning methods, such as deep neural networks (DNN), have achieved remarkable success in a number of complex data processing tasks. These methods have arguably had their strongest impact on tasks such as image and audio processing - data processing domains in which humans have long held clear advantages over conventional algorithms. In contrast to biological neural systems, which are capable of learning continuously, deep artificial networks have a limited ability for incorporating new information in an already trained network. As a result, methods for continuous learning are potentially highly impactful in enabling the application of deep networks to dynamic data sets. Here, inspired by the process of adult neurogenesis in the hippocampus, we explore the potential for adding new neurons to deep layers of artificial neural networks in order to facilitate their acquisition of novel information while preserving previously trained data representations. Our results on the MNIST handwritten digit dataset and the NIST SD 19 dataset, which includes lower and upper case letters and digits, demonstrate that neurogenesis is well suited for addressing the stability-plasticity dilemma that has long challenged adaptive machine learning algorithms.
Deposition of platelets and fibrin on chemically modifide collagen hollow fibers. (1976)

A new technique was devised for interaction studies between human blood and chemically modified amorphous collagen surfaces. Blood is drawn directly from an antecubital vein, through saline-filled collagen hollow fibers, at either constant flow for varying time or constant time at varying flow. Platelets and fibrin were deposited more rapidly and in greater numbers on methylated surfaces and more slowly and to a lesser extent on succinylated surfaces than on native surfaces. Increasing blood flow was associated with increased fibrin formation. Adherent platelets spread over 3-8 mu of methylated surface, but retained a spherical shape (1-2 mu) on succinylated and native surfaces. Thus, charge modification of collagen significantly alters platelet adhesion, subsequent platelet morphology, and fibrin deposition. Methylated surfaces are thrombogenic and succinylated ones are relatively thrombo-resistant.
Fluoroquinolone AUIC Break Points and the Link to Bacterial Killing Rates (2003)

Evidence from in vitro and animal models favors the use of AUIC values >250 for rapid bactericidal action, regardless of whether the organism is gram-negative or gram-positive.
Analysis of an RF induction plasma torch with a permeable ceramic wall (1989)

Abstract An analysis is made for an rf plasma torch with a permeable ceramic tube as the contaminant tube. The temperature, flow, and electromagnetic fields in the rf torch are obtained along with the argon flow, the gas and matrix temperatures. The results show that about 80% of the plasma radiation losses are trapped by the ceramic wall. For optimum cooling, a wall with variable thickness is proposed. The results also indicate that argon is not a suitable gas for cooling the permeable wall.
Optimization and Parallelization on a Multimeida Application (2007)

As digital video data becomes more pervasive, mining information from multimedia data becomes increasingly important. However, the huge computational requirement prohibits its wide use in practice. This paper presents some optimization techniques and parallel approaches to accelerate a real video mining application -goalmouth detection in soccer video. By tuning the application performance with efficient optimization techniques (fast lookup tables, SIMD technology, and cache blocking) and exploiting the thread level parallelism, we enable the real time processing for this application on Intel latest dual core desktop machine -Core 2 Dual. Our study shows that with proper optimization and parallelization, multimedia mining can be used widely in our daily life soon.
Groupwise Processing of Relational Queries (1997)

In this paper, we define and examine a particu-lar class of queries called group queries. Group queries are natural queries in many decision-support applications. The main characteristic of a group query is that it can be executed in a group-by-group fashion. In other words, the underlying relation(s) can be partitioned (based on some set of attributes) into disjoint groups, and each group can be processed separately. We give a syntactic criterion to identify these queries and prove its sufficiency. We also prove the strong result that every group query has an equivalent formulation that satisfies our syntactic criterion. We describe a general evaluation technique for group queries, and demonstrate how an optimizer can determine this plan. We then consider more complex queries whose components are group queries with poten-tially different partitioning attributes. We give two methods to identify group query components within such a query. We also give some per-formance results for group queries expressed in standard SQL, comparing a commercial database system with our optimized plan on top of the same commercial system. These results indicate that there are significant potential performance improvements.
Visualizing a scalar field on an N-dimensional lattice (1990)

The authors address the problem of visualizing a scalar dependent variable which is a function of many independent variables. In particular, cases where the number of independent variables is three or greater are discussed. A new hierarchical method of plotting that allows one to interactively view millions of data points with up to 10 independent variables is presented. The technique is confined to the case where each independent variable is sampled in a regular grid or lattice-like fashion, i.e., in equal increments. The proposed technique can be described in either an active or a passive manner. In the active view the points of the N-dimensional independent variables lattice are mapped to a single horizontal axis in a hierarchical manner, while in the passive view an observer samples the points of the N-dimensional lattice in a prescribed fashion and notes the values of the dependent variable. In the passive view a plot of the dependent variable versus a single parametric variable, which is simply the sampling number, forms the multidimensional graph. >
Glial growth factors I-III are specific mitogens for glial cells (1996)

Recently we identified three novel Schwann cell mitogens named GGF (glial growth factor)-I (34 kDa), GGF-II (59 kDa), and GGF-III (45 kDa), and provided evidence that they are three distinct but structurally related members of a larger family of factors, which includes heregulin, neu differentiation factor, and acetylcholine receptor-inducing activity (ARIA). We report here the characterization of the mitogenic and trophic activities for all three forms of GGF on rat Schwann cells and several other cell types. GGF-I, GGF-II, and GGF-III are potent mitogens for rat Schwann cells in vitro at nanomolar concentrations, whereas at lower concentrations they promote Schwann cell survival, in the absence of cAMP elevating agents. Forskolin, an adenylate cyclase activator, potently synergizes with the GGFs by an indirect mechanism, possibly involving transcriptional activation of GGF receptor(s). In addition, the GGFs stimulate DNA synthesis in rat glioma C6 cells, and in SK-BR-3 cells, which overexpress the p185 neu/erbB2. Fibroblasts obtained from different sources are weakly stimulated by GGFs, whereas PC12 cells are unable to respond under a variety of experimental conditions. These observations are consistent with the proposal that GGF-I, GGF-II, and GGF-III are a set of potent glial cell mitogens and putative ligands of members of the EGF receptor family, namely p185 neu/erbB2, p160/erbB3, and p180/erbB4, which may play important roles in the development, regeneration, and tumor biology of the peripheral nervous system.
The relationships between risk factors and the distribution of retinopathy lesions in type 2 diabetes (2006)

The localized distribution of retinopathy lesions does not correlate with known risk factors and background factors for the development of diabetic retinopathy in the early stages of the disease. Future improvements of grading systems for diabetic retinopathy should focus on a quantification of the overall number and dynamics of retinopathy lesions in the early stages of retinopathy and the regional distribution and dynamics of lesions in more advanced stages of retinopathy.
A STATIC SOFTWARE BIRTHMARK BASED ON USE-DEFINE CHAINS FOR DETECTING THE THEFT OF JAVA PROGRAMS (2011)

Software birthmarking is a new technique used to detect the theft of programs. In the technique, a software birthmark is the inherent invariable features of a program that can be used to identify the program. Some typical semantics-preserving transformations will have a significant impact on order and frequency of instructions in programs. By introducing dataflow analysis techniques, dependencies of instructions that define or use variables in programs are established. The relations between these instructions can reduce the effect of semantics-preserving transformations such as shuffle stack operation, add fake exception, change switch statements and encrypt string in SmokeScreen. Classes are compared by the optimal matching algorithm. Thus a novel method of software birthmarking based on use-define chains is presented.
Path generation for ground target tracking of airplane-typed UAV (2009)

Airplane-typed UAV can perform a ground target tracking effectively by its long endurance performance. In this study, the ground target tracking with constant relative distance of target to UAV is considered. The target positioning by using flight attitude, altitude and camera pan and tilt angle is described. And by considering a circle which the center is at the target position and the radius equals to desired relative distance of target to UAV, the heading path is generated in order to fly to the circumference of the circle. Simulations were performed with a target moving faster and slower than stall speed of UAV. In the case of target moving fast, the UAV can track the target well also direction and relative distance. In the case of target moving slow, even if the UAV cannot maintain the relative distance as desired, but the UAV can track the direction of the target.
Research on A Decision Support System for Inventory Management Based on Multi-Agent (2008)

To overcome the difficulties of the traditional inventory management system in adapting environmental change, the decision support system for inventory management was developed based on multi-agent. The paper analyzed the feasibility of applying the Agent technology in the inventory management decision support system, and presented the framework of the system, the functions of its sub-agents and an example of the agent's structure as well as the system's working flow. The technology of the Distributed Component Object Model (DCOM) is applied to realize the sharing of distributed resources and information in the system. The communication in the multi-agent is carried out by the message transfer. The operation of the system validates that the intelligence and decision-making efficiency have been improved by using multi-agent technology.

Ibopamine kinetics after a single oral dose in patients with congestive heart failure. (1988)

The kinetics of ibopamine, the 3,4-diisobutyryl ester of N-methyldopamine (epinine), was assessed in 27 patients with congestive heart failure (CHF) and 8 healthy normal subjects (NS). Nine patients were in functional class IV according to the NYHA definition, 9 in class III and 9 in class II. Ibopamine was administered at a single oral dose of 100 mg. Epinine, both free and total (mainly conjugated), plasma concentrations and urinary recoveries of total epinine, HVA and DOPAC were studied. The results showed that ibopamine kinetics is not substantially different in CHF patients and in NS. In both groups the absorption of the drug was equally prompt and elevated. Mean Cmax, tmax and AUC infinity values of total epinine in CHF patients did not differ significantly from those in NS. In CHF patients t 1/2 of total epinine was significantly higher than in NS (4.1 +/- 0.2 h vs 3.1 +/- 0.2 h, mean +/- SE). Mean Cmax, tmax, AUCt and MRT values of free epinine in CHF patients were not significantly different from those in NS. The urinary recovery of the 3 metabolites considered together was comparable in CHF patients and in NS. The mean +/- SE total urinary recoveries in the 24 h after dosing, expressed as percentages of the administered dose, were 60 +/- 3 in CHF patients and 69 +/- 4 in NS. Conjugated epinine in urine was found to be constituted by 3-O-sulfate (84%) and 4-O-sulfate (16%).
High-Throughput Method Development for Sensitive, Accurate, and Reproducible Quantification of Therapeutic Monoclonal Antibodies in Tissues Using Orthogonal Array Optimization and Nano Liquid Chromatography/Selected Reaction Monitoring Mass Spectrometry (2012)

Although liquid chromatography/mass spectrometry using selected reaction monitoring (LC/SRM-MS) holds great promise for targeted protein analysis, quantification of therapeutic monoclonal antibody (mAb) in tissues represents a daunting challenge due to the extremely low tissue levels, complexity of tissue matrixes, and the absence of an efficient strategy to develop an optimal LC/SRM-MS method. Here we describe a high-throughput, streamlined strategy for the development of sensitive, selective, and reliable quantitative methods of mAb in tissue matrixes. A sensitive nano-LC/nanospray-MS method was employed to achieve a low lower limit of quantification (LOQ). For selection of signature peptides (SP), the SP candidates were identified by a high-resolution Orbitrap and then optimal SRM conditions for each candidate were obtained using a high-throughput, on-the-fly orthogonal array optimization (OAO) strategy, which is capable of optimizing a large set of SP candidates within a single nano-LC/SRM-MS run. Using the optimized conditions, the candidates were experimentally evaluated for both sensitivity and stability in the target matrixes, and SP selection was based on the results of the evaluation. Two unique SP, respectively from the light and heavy chain, were chosen for quantification of each mAb. The use of two SP improves the quantitative reliability by gauging possible degradation/modification of the mAb. Standard mAb proteins with verified purities were utilized for calibration curves, to prevent the quantitative biases that may otherwise occur when synthesized peptides were used as calibrators. We showed a proof of concept by rapidly developing sensitive nano-LC/SRM-MS methods for quantifying two mAb (8c2 and cT84.66) in multiple preclinical tissues. High sensitivity was achieved for both mAb with LOQ ranged from 0.156 to 0.312 μg/g across different tissues, and the overall procedure showed a wide dynamic range (≥500-fold) and good accuracy [relative error (RE) < 18.8%] and precision [interbatch relative standard deviation (RSD) < 18.1%, intrabatch RSD < 17.2%]. The quantitative method was applied to a comprehensive investigation of the steady-state tissue distribution of 8c2 in wild-type mice versus those deficient in FcRn α-chain, FcγIIb, and FcγRI/FcγRIII, following a chronic dosing regimen. This work represents the first extensive quantification of mAb in tissues by an LC/MS-based method.

High temperature (730°C) rapid thermal processing of a Ti layer capped with was found to yield the stable C54 material phase. formed on moderately doped mono‐ and poly‐Si can withstand aggressive environments of low pressure chemical vapor deposited tetraethylorthosilicate deposition, while the films formed on more heavily doped substrates were found to require additional stabilization at higher temperatures.
Preparation of Substituted Piperazinones via Tandem Reductive Amination−(<i>N</i>,<i>N</i>‘-Acyl Transfer)−Cyclization (2002)

[reaction: see text] A one-pot, tandem reductive amination-transamidation-cyclization reaction was employed to produce substituted piperazin-2-ones in good yields. Various amino acid methyl esters and transferable acyl groups were examined to establish the reaction's scope.
Experimental study on discretely modulated continuous-variable quantum key distribution (2010)

We present a discretely modulated continuous-variable quantum key distribution system in free space by using strong coherent states. The amplitude noise in the laser source is suppressed to the shot-noise limit by using a mode cleaner combined with a frequency shift technique. Also, it is proven that the phase noise in the source has no impact on the final secret key rate. In order to increase the encoding rate, we use broadband homodyne detectors and the no-switching protocol. In a realistic model, we establish a secret key rate of $46.8$ kbits/s against collective attacks at an encoding rate of $10$ MHz for a $90%$ channel loss when the modulation variance is optimal.
