Implementation of an N*N Fourier transform in order N instructions on a SIMD array (2003)

Summary form only given. The discrete Fourier transform has been implemented on a single-instruction, multiple-data (SIMD) machine. The implementation demonstrates how an algorithm that is unsuited for use on a sequential machine can be very effective in a parallel machine. The SIMD machine is based on the Geometric Arithmetic Parallel Processor (GAPP). The Bluestein chirp algorithm, a variation of the chirp-Z algorithm, is the key to parallelizing the Fourier transform. When the chirp-Z is adapted to the parallel architecture of the GAPP array, the transform is reduced to O(N) operations as compared to O(N*N log N) on sequential machines. The GAPP array used to implement this algorithm is a 108*384 array. Each processing element is a one-bit serial ALU with 128 bits of RAM. Each processor is connected to its four nearest neighbors (north, south, east, and west) in a mesh configuration.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Gender differences and fears in patients awaiting coronary artery bypass grafting (2001)

The study aimed at ascertaining the gender differences and fears among patients awaiting coronary artery bypass grafting. Data were collected using a mailed questionnaire from patients (n=207) scheduled for coronary artery bypass grafting at one hospital. Intensity of fear was measured on a 10-point scale including 12 objects of fear. The results showed that demographic data, lifestyle and functional capacity differed between the sexes. Patients' fears differed with respect to their objects and intensity, with women reporting more intense fears. Men also had fears, but the objects of fear differed from those in women. Apart from gender, the intensity of fear was associated with physical exercise, emotional problems and depression. Nursing interventions could be developed to meet the different needs for information and support, especially among women but also among men, to relieve their fears during the wait for coronary artery bypass grafting.
Triple Innominate Osteotomy for Acetabular Dysplasia (1993)

Fifty-six hips in 44 patients that underwent triple innominate osteotomy were reviewed. Average follow-up was 7 years (range 2-12 years). Patients were evaluated with regard to any postoperative pain and any improvement in function and as to whether they would recommend the procedure. Improvement in pain and function was considered good in 53 hips. Three hips were considered failures. Forty-two of 44 patients strongly recommended the procedure. Two patients would not recommend the procedure. In all, 94% of patients had improvement in both pain and function and recommended the operation.

Global Analysis of the Membrane Subproteome of <i>Pseudomonas aeruginosa</i> Using Liquid Chromatography-Tandem Mass Spectrometry (2004)

Pseudomonas aeruginosa is one of the most significant opportunistic bacterial pathogens in humans causing infections and premature death in patients with cystic fibrosis, AIDS, severe burns, organ transplants, or cancer. Liquid chromatography coupled online with tandem mass spectrometry was used for the large-scale proteomic analysis of the P. aeruginosa membrane subproteome. Concomitantly, an affinity labeling technique, using iodoacetyl-PEO biotin to tag cysteinyl-containing proteins, permitted the enrichment and detection of lower abundance membrane proteins. The application of these approaches resulted in the identification of 786 proteins. A total of 333 proteins (42%) had a minimum of one transmembrane domain (ranging from 1 to14) and 195 proteins were classified as hydrophobic based on their positive GRAVY values (ranging from 0.01 to 1.32). Key integral inner and outer membrane proteins involved in adaptation and antibiotic resistance were conclusively identified, including the detection of 53% of all predicted opr-type porins (outer integral membrane proteins) and all the components of the mexA-mexB-oprM transmembrane protein complex. This work represents one of the most comprehensive proteomic analyses of the membrane subproteome of P. aeruginosa and for prokaryotes in general.
Androgen insensitivity syndrome (2012)

Androgen insensitivity syndrome (AIS) is a disorder caused by a mutation of the gene encoding the androgen receptor (AR; Xq11-q12). The prevalence of AIS has been estimated to be one case in every 20,000 to 64,000 newborn males for the complete syndrome (CAIS), and the prevalence is unknown for the partial syndrome (PAIS). The symptoms range from phenotypically normal males with impaired spermatogenesis to phenotypically normal women with primary amenorrhea. Various forms of ambiguous genitalia have been observed at birth. The diagnosis is confirmed by determining the exact mutation in the AR gene. PAIS individuals require precise diagnosis as early as possible so that the sex can be assigned, treatment can be recommended, and they can receive proper genetic counseling. After birth, differential diagnosis should be performed using other forms of abnormal sexual differentiation of primary amenorrhea. The treatment of AIS is based on reinforcement sexual identity, gonadectomy planning, and hormone replacement therapy. The prognosis for CAIS is good if the testicular tissue is removed at the appropriate time. For PAIS, the prognosis depends on the ambiguity of the genitalia and physical and psychosocial adjustment to the assigned sex.
<title>Parallel-distributed mobile robot simulator</title> (1996)

The aim of this project is to achieve an autonomous learning and growth function based on active interaction with the real world. It should also be able to autonomically acquire knowledge about the context in which jobs take place, and how the jobs are executed. This article describes a parallel distributed movable robot system simulator with an autonomous learning and growth function. The autonomous learning and growth function which we are proposing is characterized by its ability to learn and grow through interaction with the real world. When the movable robot interacts with the real world, the system compares the virtual environment simulation with the interaction result in the real world. The system then improves the virtual environment to match the real-world result more closely. This the system learns and grows. It is very important that such a simulation is time- realistic. The parallel distributed movable robot simulator was developed to simulate the space of a movable robot system with an autonomous learning and growth function. The simulator constructs a virtual space faithful to the real world and also integrates the interfaces between the user, the actual movable robot and the virtual movable robot. Using an ultrafast CG (computer graphics) system (FUJITSU AG series), time-realistic 3D CG is displayed.
Assessment of drug interaction potential between the HCV direct-acting antiviral agents elbasvir/grazoprevir and the HIV integrase inhibitors raltegravir and dolutegravir (2018)

Elbasvir or grazoprevir co-administered with raltegravir or dolutegravir resulted in no clinically meaningful drug-drug interactions and was generally well tolerated. These results support the assertion that no dose adjustments for elbasvir, grazoprevir, raltegravir or dolutegravir are needed for co-administration in HCV/HIV-coinfected people.
Transient natural convection in an internally heated fluid layer. Topical report, June 1975--June 1976 (1976)

An experimental study of the transient response of a horizontal fluid layer subjected to a step change in internal energy generation has been conducted to determine the time scales for the development and decay of natural convection driven solely by the internal heat release. The layer is bounded from above by a rigid, constant temperature surface and from below by a rigid, insulated surface. Two types of unsteady convection processes are considered. In the first, the layer is brought to a motionless, isothermal state, and internal energy generation is suddenly started. In the second, steady natural convection is the initial state, and internal energy generation is suddenly stopped. For both cases, the time required for the development of the final steady state is determined by measuring the temperature response of the fluid with a small thermocouple probe. The time required for the development of the maximum temperature difference in the layer with internal generation and the time required for the complete decay of the maximum temperature difference of steady convection at a given Rayleigh number when internal energy generation is suddenly stopped are correlated with the Rayleigh number in equations which will find general application in PAHR problems in nuclearmore » power reactors and particularly in the analysis of the small-time thermal response of in-vessel and ex-vessel molten core retention devices.« less

Methyl 8-formyl-6-oxoöxyoctanoate (III), obtained by application of formic acid to methyl 8-chloro-6-oxoöctanoate (I) or methyl 6-oxo-7-octenoate (II), was submitted to high-pressure reduction, followed by bromination and esterification, to form ethyl 6, 8-dibromoöctanoate (VI). α-Lipoic acid (XI) was prepared by the reaction of alkyl 6, 8-dihaloöctanoate (VI and VII) with sodium trithiocarbonate (VIII).
Evolution of Human Immunodeficiency Virus Type 1 (HIV-1) Resistance Mutations in Nonnucleoside Reverse Transcriptase Inhibitors (NNRTIs) in HIV-1-Infected Patients Switched to Antiretroviral Therapy without NNRTIs (2003)

We studied the evolution of nonnucleoside reverse transcriptase inhibitor (NNRTI) resistance mutations among 29 human immunodeficiency virus type 1 (HIV-1)-infected patients who experienced virologic failure when receiving an NNRTI-containing regimen (nevirapine, delavirdine, or efavirenz) and subsequently switched to antiretroviral therapy without NNRTIs. Genotypic resistance was determined from plasma samples collected at the time of NNRTI withdrawal (baseline) and during follow-up. At baseline, 83% of patients had more than two thymidine analog resistance mutations (TAMs), and all had NNRTI resistance mutations. Mutations at codons 103, 181, and 190 were found in 62, 62, and 34% of the patients, respectively. Follow-up samples were available after a median time of 6 months in all patients and at 12 months in 22 patients. The mean number of resistance mutations to NNRTIs was significantly lower at months 6 (1.34 +/- 1.04) and 12 (1.18 +/- 1.05) than at month 0 (2.03 +/- 1.02) (P < 0.009). The percentages of patients with at least one NNRTI resistance mutation were 100, 76, and 73% at baseline, month 6, and month 12, respectively (P < 0.0044). Overall, 70% of the patients had a mutation at codon 103 or 181 at month 12. The mean number of TAMs did not vary significantly during follow-up. Our data show that, in the context of maintained antiretroviral therapy, NNRTI resistance mutations persist in two-thirds of the patients in spite of NNRTI withdrawal. These results argue for the low impact of NNRTI resistance mutations on viral fitness and suggest that resistance mutations to different classes of drugs are associated on the same genome, at least in some of the resistant strains.
Angle-resolved inverse photoelectron spectroscopy studies of CdTe(110), CdS(11<i>2¯</i>0), and CdSe(11<i>2¯</i>0) (1987)

The conduction-band structures of CdTe(110), CdS(112\ifmmode\bar\else\textasciimacron\fi{}0), and CdSe(112\ifmmode\bar\else\textasciimacron\fi{}0) have been studied using angle-resolved inverse photoelectron spectroscopy. With normally incident electrons substantial parts of the conduction bands have been observed and several critical points determined. The energy positions of these are compared with theoretical predictions. Clear discrepancies are found, especially for the wurtzite crystals CdS and CdSe. Unoccupied surface resonances have been observed on CdTe(110) and on CdS(112\ifmmode\bar\else\textasciimacron\fi{}0). Those associated with the broken bonds on the surfaces are found 1.4 and 1.2 eV above the conduction-band minimum (CBM), respectively. On CdS(112\ifmmode\bar\else\textasciimacron\fi{}0) a second surface resonance is found 3.2 eV above the CBM, being split off from the ${M}_{1}$ point in the Brillouin zone. A fluorescence process involving the Cd 4d level has been observed in all three materials. This yields information on the partial density of p states in the valence band.

[Weibel-Palade bodies: unique secretory organelles within endothelial cells]. (2004)

Vascular endothelial cells contain typical elongated vesicles, known as Weibel-Palade bodies. These organelles serve as a storage compartment for a variety of proteins that play a part in controlling vascular homeostasis, including von Willebrand factor, endothelin, P-selectin and interleukin-8. Upon activation of endothelial cells, Weibel-Palade bodies are translocated to the periphery of the cell and there fuse with the plasma membrane to release their contents into the blood circulation and subendothelial connective tissue. This process provides an adequate means by which endothelial cells can actively participate in controlling the arrest of bleeding upon vascular damage or modulate inflammatory reactions and other physiological and pathophysiological processes at the blood-tissue interface. Weibel-Palade bodies may also move to the nucleus of the cell, thus escaping secretion. This phenomenon may play a part in controlling stimulus-induced exocytosis.

Determination of resist and development parameters for i-line photoresist AZ 7800 by experiment and simulation (1997)

We present a method to improve the simulation accuracy by adjustment of the resist and process parameters. The parameters are fitted by comparison of simulated and experimental determined lithographic functions: swing curves, development rate function and focus latitude curves for different doses within an accuracy of plus or minus 30 nm. Therefore we can use the simulation to support the process optimization.

Mode Expansion in Equilibrium Statistical Mechanics. I. General Theory and Application to the Classical Electron Gas (1970)

A new expansion for the Helmholtz free energy of a classical system is presented. The potential energy of the system is assumed to be composed of two parts: a “reference system” potential energy and a perturbation potential, which is the sum of two-particle potentials. The two-particle perturbation potential energy is assumed to have a Fourier transform. Collective variables, which are the Fourier transforms of the single-particle density, are introduced, and the canonical ensemble partition function is expressed as an infinite series. The first term in the result for the Helmholtz free energy is the reference system free energy. The second is a mean field term, and the third is the random phase approximation. Subsequent terms involve correlations among the collective variables in the reference system. The general results are applied to the special case in which the reference system is the ideal gas. A density and temperature dependent renormalized potential arises from the analysis in a straightforward way. When the results are specialized to the case of the Coulomb potential, agreement with the ionic cluster theory is obtained, and the renormalized potential is the usual Debye–Hückel potential. Further applications of the technique are mentioned.

We demonstrate direct generation of wavelength-multiplexed polarization entangled photons from a single chip. The concurrence of 0.98±0.01, and bandwidth spanning S-C-L bands are the highest reported in waveguide sources, setting new records for monolithic quantum technologies.
Influence of amide content on the crystal structure of chitin (2006)

Abstract The crystalline structure of chitin and chitosan was investigated by X-ray diffraction (XRD). Chitosan filaments were prepared using a saturated solution of calcium chloride dihydrate in methanol (CaCl 2 -MeOH) as a mild solvent and the study focused on the interaction between the degree of acetylation (DA) and crystallinity. There were pronounced differences in the XRD patterns for specimens with DA values between 44.2% and 52.2%. We suggest that the crystalline structure changes from an anhydrous-type chitosan to an α-chitin type without any additives. CaCl 2 -MeOH is a good solvent for chitin and a poor solvent for chitosan and we found that it can regulate the distribution of N -acetyl glucosamine and glucosamine between amorphous and crystalline regions.

Audio structuring and personalized retrieval using ontologies (2002)

The goal of this work is to improve the accuracy (precision and recall) and communication effectiveness of a database system response to a user information request, by utilizing a domain-specific ontology. This ontology is employed along with user profile information, to automatically select and deliver appropriate information units from a database. Specifically, the focus is on multimedia audio databases. We are developing a Personal AudioCast system at the USC Integrated Media Systems Center which creates and delivers to an end-user personalized audio programs constructed from an audio database. Techniques are developed to segment and structure audio information, process user requests to generate custom audio results, create and optimize SQL queries, and present the results to the user.
Modulation of monocyte chemotactic function in inflammatory lesions. Role of inflammatory mediators (1991)

Monocyte recruitment and accumulation in the synovial tissue is pivotal in the evolution of rheumatoid arthritis (RA). In the present study we examined the chemotactic potential of monocytes obtained from synovial fluid (SF) of patients with RA. Functionally, SF monocytes exhibited greatly diminished chemotactic activity to C5a compared with monocytes from the peripheral blood. In contrast, their chemotactic responsiveness to the synthetic peptide, FMLP, was nearly normal. To define a mechanism for this differential chemotactic dysfunction, cell-surface receptors for C5a (C5aR) and FMLP (FMLP-R) were evaluated. Whereas FMLP-R expression was similar on both blood and inflammatory monocytes, C5aR expression was markedly reduced on SF cells. Because decreased C5a binding in certain RA SF samples could not be attributed to free C5a, known or suspected components of inflammatory SF were evaluated for their ability to modulate chemotactic ligand receptors. Bacterial products including LPS and streptococcal cell walls, which are potent monocyte activators, down-regulated C5aR without affecting FMLP-R. Moreover, the cytokines IFN-gamma and granulocyte-macrophage-CSF selectively decreased C5aR in parallel with decreased in vitro chemotactic activity to C5a. Thus, these data indicate that 1) synovial effusions may contain C5a and/or inflammatory mediators that modulate phenotypic and functional changes in monocytes, 2) chemotactic ligand receptors are independently regulated in inflammatory lesions, and 3) decreased C5aR expression and chemotactic potential likely provide a mechanism whereby monocyte-macrophages persist within the inflamed synovium.
Increased Oral Fibroblast Lifespan Is Telomerase-independent (2009)

Oral mucosal wound-healing is characterized by rapid re-epithelialization and remodeling, with minimal scar formation. This may be attributed to the distinct phenotypic characteristics of the resident fibroblasts. To test this hypothesis, we investigated patient-matched oral mucosal and skin fibroblasts. Compared with skin fibroblasts, oral mucosal fibroblasts had longer proliferative lifespans, underwent more population doublings, and experienced senescence later, which was directly related to longer telomere lengths within oral mucosal fibroblasts. The presence of these longer telomeres was independent of telomerase expression, since both oral oral mucosal fibroblasts and skin fibroblasts were negative for active telomerase, as assessed according to the Telomeric Repeat Amplification Protocol. This study has demonstrated that, compared with skin fibroblasts, oral mucosal fibroblasts are 'younger', with a more embryonic/fetal-like phenotype that may provide a notable advantage for their ability to repair wounds in a scarless fashion.
