A Parallel Quantum Computer Simulator (2016)

The unique principles of quantum mechanics may one day enable computers to perform operations that would be impossible on a classical computer. Although no one knows whether it will be possible to build a large-scale, functional, and stable quantum computer, researchers can study quantum-mechanical systems and develop algorithms and circuits by simulating quantum systems in software. Performance and memory bottlenecks prevent most current quantum computer simulators from being able to simulate quantum systems that are large enough to be useful. In this thesis, we develop a matrix-free sequential quantum computer simulator to vastly improve both time and memory performance of sequential code on a single processor. Next, we distribute the matrix-free algorithm over multiple parallel processors using the Message Passing Interface in order to simulate quantum systems that are too large to reside wholly within the memory of a single processor. Finally, we simulate various quantum circuits using the Hamming high-performance computing cluster in order to conduct algorithmic analysis.
Hwa-Byung: a Korean culture-bound syndrome? (1983)

The author reports three cases of Hwa-Byung, a Korean folk illness ordinarily understood by patients and families to be a physical affliction despite the fact that its manifestations include both physiological and psychological symptoms. In addition, the patient often recognizes interpersonal conflicts and anger as precipitating factors. In the three cases reported, the patients also identified an epigastric mass that was not present on physical examination. Symptoms were accompanied by a fear of impending death that was not easily dispelled by medical reassurance. The author discusses the role of depression in the symptom formation of Hwa-Byung as well as the treatment implications.
Solid-liquid separation via filtration (1997)

Solid-liquid separation is a truly ubiquitous unit operation. It can be found in all parts of a manufacturing process, from raw material purification, through product separation, all the way to waste management. Yet, common as it is, solid-liquid separation is generally not well understood, partly because of the complex nature of fluid-particle systems. Because of this lack of knowledge, such operations are often the problem area or bottleneck in a plant. Yet, with the growing emphasis on process efficiency and waste management, there is an enormous need for more understanding in this technology. It is the objective of this article to present an overview of common solid-liquid separation operations, so that users are aware of all the available options. This article will cover filtration techniques, in which a septum is used to separate particles from a liquid.

Recovering from the ShakeOut Earthquake (2011)

Recovery from an earthquake like the M7.8 ShakeOut Scenario will be a major endeavor taking many years to complete. Hundreds of Southern California municipalities will be affected; most lack recovery plans or previous disaster experience. To support recovery planning this paper 1) extends the regional ShakeOut Scenario analysis into the recovery period using a recovery model, 2) localizes analyses to identify longer‐term impacts and issues in two communities, and 3) considers the regional context of local recovery. Key community insights about preparing for post‐disaster recovery include the need to: geographically diversify city procurement; set earthquake mitigation priorities for critical infrastructure (e.g., airport), plan to replace mobile homes with earthquake safety measures, consider post‐earthquake redevelopment opportunities ahead of time, and develop post‐disaster recovery management and governance structures. This work also showed that communities with minor damages are still sensitive to regional infrastructure damages and their potential long‐term impacts on community recovery. This highlights the importance of community and infrastructure resilience strategies as well.

Cu Barrier Seed Innovation for EM Improvement (2014)

Cu barrier seed is a key process in Cu interconnect. Continuous improvement in Cu barrier and seed processes and hardware has enabled improvement in Cu gap fill and effective suppression of Cu diffusion and EM (electron migration). This paper addresses innovations in Cu barrier and seed aimed at suppressing EM. Both barrier and seed processes are crucial for EM qualification. In vias, a robust and continuous barrier reduces Cu diffusion at the interface; robust punch through helps via clean; and the resputtering process can optimize via profile and current distribution. Most early failures in the via could be fixed by the PVD (physical vapor deposition) Ta(N) process. Cu alloy seed was later developed to increase EM life time. CuAl alloy can retard Cu migration at the grain boundary and interface; CuMn alloy can create a self-formed barrier. Co wetting and capping layers are the newest approaches for suppressing EM failures at 32nm and below. The entire Cu line can be encapsulated by a Co layer, leaving no weak spots in the top and sidewall interface and blocking the rapid diffusion path of Cu. Compared to CuMn, the Co solution also offers advantages for gap fill and Rc reduction.
Analysis of Electrochemical Noise Data for Polymer Coated Steel in the Time and Frequency Domains (1996)

Electrochemical noise data were collected by remote control during exposure of two coating systems applied on steel to natural seawater.The experimental data were analyzed in the time and frequency domains. The noise resistance, Rn, was calculated as the ratio of the standard deviations of potential σ{V(t} and current noise σ{l(t} fluctuations. After fast Fourier transform of the experimental data into the frequency domain, spectral noise plots were obtained from which the spectral noise resistance, , was determined. The spectral noise plots were compared to impedance spectra and certain limitations of the electrochemical noise analysis technique were noted for protective coatings at early stages of exposure. A unique relationship of Rn with the protective properties of polymer coatings remains questionable.

Biological applications of functionalized calixarenes (2012)

The functionalized calixarene derivatives exhibit remarkable properties towards organic and bioorganic molecules. However, the ability of calixarene derivatives to form stable complexes with biomolecules allows them to be applied for the development of biosensors and in the field of biology, biotechnology, and drug discovery. The applications of the functionalized calixarenes are summarized in this review, and an outlook for the future developments is discussed. A brief survey (of the last 10 years) on their biological application in various fields is also considered (199 references).
Effect of low-intensity pulsed ultrasound on prepubertal rat testis. (1991)

The testes of prepubertal male rats (N = 12) aged 21 days were stimulated with low-intensity pulsed ultrasound (1.5-MHz frequency, 1-KHz repetition pulse rate, 200-microseconds pulse width, 30-V peak-to-peak amplitude and 20-mW/cm2 intensity) applied to the skin for 20 min/day for 7 days. Control rats (N = 8) were manipulated in the same manner but not submitted to ultrasound. Ultrasound stimulation promoted a significant increase in plasma testosterone (62%) leading to a significant increase in seminal vesicle relative weight (35%) as well as an increase in the fructose (92%) and DNA (200%) contents of the gland. No differences were detected between ultrasound-treated and control animals in terms of body weight and the relative weights of testis, cauda epididymidis, testis DNA and mitosis.
Channel-Adaptive Hybrid ARQ/FEC for Robust Video Transmission Over 3G (2005)

This paper addresses the important issues of error control for video transmission over 3G. Based on the time-varying wireless channel conditions and the essential defects of the traditional hybrid ARQ for real-time service, the architecture of the channel-adaptive hybrid ARQ/FEC is presented, moreover an algorithm for encoder is given to automatically adjust the parity data length and the maximum number of retransmissions. The experimental studies show that the transmission efficiency of the proposed algorithm increased 13% than the traditional hybrid ARQ.

Recent Trends in Fertility in Less Developed Countries (1983)

The rate of increase of population in less developed countries accelerated rapidly from 1850 to 1960 because of a rapid decline in mortality while fertility remained high. In the 1960's, the birth rate as a whole began to decline more rapidly than the death rate—very rapidly in some populations, most notably that of China, more gradually in others, and not at all in some of the poorest populations. The momentum of growth implies continued increase in populations for several decades even in countries where fertility has fallen the most, and very large additional increases where there has been no decline in the rate of childbearing.
ONR/Hughes High Speed Towed Array System (HSTAS) (1978)

During the reporting period (FY 1977), a High Speed Towed Array System (HSTAS) was conceived, designed, and fabricated. The system was successfully sea tested in July of 1977 in Exuma Sound in the Bahamas aboard the R/V Harris. In addition to the test being successful from the point of view of equipment operability at sea, the following program goals were achieved: a) The self noise results revealed that the 6 inch diameter module (FAM) was always quieter than the 3 inch modules, reaching a peak differential of approximately 15 dB in the frequency range between 80 Hz and 250 Hz at 18 knots towspeed. b) The demonstration (at sea) of the ability to eliminate ownship radiated noise interference from beam outputs by means of an adaptive filter employed as a noise canceller. Specifically, in the case of a broadband interfering signal, a maximum cancellation of 15 dB was achieved, while for the narrowband case the cancellation was 18 dB. For this latter effort, the R/V Harris was augmented acoustically by towing the HX-90 noise source.
Developing A Web-Based Workflow Management System In Cloud Computing Platforms (2015)

Cloud computing is the innovative and leading information technology model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort. In this paper, we aim at the development of workflow management system for cloud computing platforms based on our previous research on the dynamic allocation of the cloud computing resources and its workflow process. We took advantage of the HTML5 technology and developed web-based workflow interface. In order to enable the combination of many tasks running on the cloud platform in sequence, we designed a mechanism and developed an execution engine for workflow management on clouds. We also established a prediction model which was integrated with job queuing system to estimate the waiting time and cost of the individual tasks on different computing nodes, therefore helping users achieve maximum performance at lowest payment. This proposed effort has the potential to positively provide an efficient, resilience and elastic environment for cloud computing platform. This development also helps boost user productivity by promoting a flexible workflow interface that lets users design and control their tasks' flow from anywhere.
Molecular genotyping of sugarcane clones with microsatellite DNA markers (2003)

Molecular genotypes of 27 sugarcane clones (Saccharum hybrids) were produced with nine sugarcane microsatellites. A total of 52 alleles were identified using a capillary electrophoresis system with 41 alleles displaying varying degrees of polymorphism and the remaining 11 being monomorphic. There were eight alleles for sugarcane microsatellite SMC286CS, five for SMC334BS, eight for SMC336BS, four for SMC713BS, five for mSSCIR5, five for mSSCIR33, five for MCSA042E08, four for MCSA053C10, and eight for MCSA068G08. Presence or absence of these 52 alleles from a clone allowed the assignment of its arbitrary microsatellite genotype. The genetic relatedness among these clones was assessed using the CLUSTAL W algorithm with DNAMAN(R) software based on their arbitrary genotypes. With the exception of four clones, CP 70-321, HoCP 91-555, L 97-137 and Q124, six groups of clones were identified that shared at least 76% homology between their microsatellite genotypes. The software program also produced a bootstrapped phylogenetic tree with branch patterns that in general coincided with the putative pedigrees of these clones. The derivation of molecular genotypes such as these has enable sugarcane geneticists and breeders to verify the genetic pedigrees and purity of their sugarcane populations. These microsatellite genotypes can also aid in progeny selection and facilitate studies on allele transmission in this aneu-polyploidy crop.
A Revised Protocol for In Vitro Development of Mouse Oocytes from Primordial Follicles Dramatically Improves Their Developmental Competence1 (2003)

The objective of this study was to improve the conditions for oocyte development in vitro beginning with the primordial follicles of newborn mice. Previous studies showed that oocytes competent of meiotic maturation, fertilization, and preimplantation could develop in vitro from primordial follicles. However, the success rates were low and only one live offspring was produced (0.5% of embryos transferred). A revised protocol was compared with the original protocol using oocyte maturation and preimplantation development as end points. The percentage of oocytes maturing to metaphase II and developing to the blastocyst stage was significantly improved using the revised protocol. In addition, we compared the production of offspring from two-cell stage embryos derived from in vitro-grown and in vivo-grown oocytes. Of 1160 transferred two-cell stage embryos derived from in vitro-grown oocytes, 66 (5.7%) developed to term and 7 pups (10.6%) died at birth. The remaining 59 pups (27 females, 32 males) survived to adulthood. By comparison, of 437 transferred two-cell stage embryos derived from in vivo-grown oocytes, 76 (17.4%) developed to term and 4 (5.3%) died at birth. The remaining 72 pups (35 females, 37 males) survived to adulthood. These studies provide proof of the principle that fully competent mammalian oocytes can develop in vitro from primordial follicles and present a significant advance in oocyte culture technology.
Calcitonin Receptor mRNA is Expressed in Human Medullary Thyroid Carcinoma (1998)

We recently reported the presence of a truncated form (h-CTR2) of the human calcitonin receptor (CTR) in TT cells, a cell line derived from medullary thyroid carcinoma (MTC). This form (h-CTR2), characterized by the absence of 16 amino acids in the first intracellular domain, was also detected in two cases of MTC. In the present study we determined the expression of CTR mRNA in a larger sample, representative of the different clinical forms of MTC, and in normal thyroid. h-CTR2 was expressed in all MTC specimens (both sporadic and familial) and in the normal thyroid samples. The expression of the receptor mRNA was higher in MTC compared with normal thyroid. Moreover, CT and CTR mRNA levels were modified significantly during proliferation. This result suggests that CT may be involved in proliferation of MTC via autocrine/paracrine regulation. Calcitonin secretion by MTC may play a role in the development and spread of these tumors.
Preliminary correlations of feature strength in spark-induced breakdown spectroscopy of bioaerosols with concentrations measured in laboratory analyses (2010)

We present preliminary results that show good correlation between elemental compositions of three bioaerosol samples, as measured in the laboratory by combustion analysis and with proton-induced x-ray emission and spark-induced breakdown spectroscopy signals integrated over the entire emission time profiles. Atomic (Ca, Al, Fe, and Si) and molecular features (CN, N2 +, and OH) were observed compared to the laboratory data.
Neural crest delamination and migration: From epithelium-to-mesenchyme transition to collective cell migration (2012)

After induction and specification in the ectoderm, at the border of the neural plate, the neural crest (NC) population leaves its original territory through a delamination process. Soon afterwards, the NC cells migrate throughout the embryo and colonize a myriad of tissues and organs where they settle and differentiate. The delamination involves a partial or complete epithelium-to-mesenchyme transition (EMT) regulated by a complex network of transcription factors including several proto-oncogenes. Studying the relationship between these genes at the time of emigration, and their individual or collective impact on cell behavior, provides valuable information about their role in EMT in other contexts such as cancer metastasis. During migration, NC cells are exposed to large number of positive and negative regulators that control where they go by generating permissive and restricted areas and by modulating their motility and directionality. In addition, as most NC cells migrate collectively, cell-cell interactions play a crucial role in polarizing the cells and interpreting external cues. Cell cooperation eventually generates an overall polarity to the population, leading to directional collective cell migration. This review will summarize our current knowledge on delamination, EMT and migration of NC cells using key examples from chicken, Xenopus, zebrafish and mouse embryos. Given the similarities between neural crest migration and cancer invasion, these cells may represent a useful model for understanding the mechanisms of metastasis.
Migration and proliferation of progenitor cells in the connective tissue of rat gingival papilla (1995)

The aim of this investigation was to determine whether gingival fibroblast progenitor cells undergo division and whether there is evidence of migration of their progeny from the paravascular sites within the interdental gingival septum (IGS). 30 male hooded Lister rats aged 6 weeks, were killed in groups of ten, 3, 75 and 171 h after a single injection of tritiated thymidine. Autoradiographs were examined of transverse Historesin sections of the papilla between second and third mandibular molars in 29 specimens, taken from equidistant intervals between the col and alveolar bone crest. Median grain counts in the whole papilla were greatest within 10 microns of blood vessels at 3 h (p < 0.02) and decreased throughout the papilla with time (p < 0.0001). The median grain counts at level 5, nearest the periodontal ligament, were greatest at all times (p < 0.01). The distance of labelled nuclei from blood vessel walls increased with time, most notably at level 5 (p < 0.001). The mean Clustering Index increased (p < 0.01) from 4.6% at 3 h to 12.3% and 11.6% at 75 h and 171 h respectively. At 75 h, the median grain count of clustered nuclei was smaller (p < 0.01) than that of non-clustered nuclei. These data are consistent with the occurrence of clonal division and migration within the IGS and the presence of a slowly cycling cell population near to the periodontal ligament.
Length Measurement by Fringe Counting (1959)

A reversible fringe counter has been constructed and its performance examined. A counting rate of 100 fringes per second over a path difference exceeding 20 cm was obtained. The fringe excess fraction at zero path difference could be determined to 0.001 fringe, and a relative precision of about 1:108 was achieved at a path difference of 6.4 cm.
