Modeling and Optimization of High Frame Rate Video Transmission Over Wireless Networks (2015)

High frame rate (HFR) video is emerging as a new paradigm in popular multimedia applications (e.g., cloud gaming) to achieve smooth viewing experience perceived by end-users. In the context of HFR streaming video, end-to-end distortion and sending frame rate are equally important to the perceptual quality. This study presents a modeling-based approach to optimizing the HFR video transmission over wireless networks. First, we develop an analytical model dubbed FRIED (Frame Rate versus vIdEo Distortion) to characterize the tradeoff between sending frame rate and end-to-end video distortion. Second, we propose a Joint frAme Selection and FEC (Forward Error Correction) cOding (JASCO) approach based on the FRIED model to optimize the transmission performance. The efficacy of the proposed JASCO is evaluated through extensive semi-physical emulations in Exata involving H.264 video streaming. Experimental results show that JASCO outperforms the reference approaches in improving video peak signal-to-noise ratio (PSNR) at the same frame rate. Or conversely, JASCO is able to achieve higher received frame rate while guaranteeing the same video PSNR.
Experimental Study on Friction Noise of Dry Rough Surfaces (2008)

This paper presents an experimental study of the friction noise, between two rough and dry surfaces. Two different geometries of contact have been studied: flat-flat contact and sphere-flat contact. The domain of interest is the dry contact under light pressure where the roughness is the dominant cause of noise. In agreement with some other studies, it has been observed that the sound pressure level Lp (dB) is a logarithmic function of the surface roughness and the sliding speed. However, the exponent of the logarithmic law between sound pressure level and surface roughness largely depends on the topography of the sliding surfaces. On the other hand, the exponent of the law between sound pressure level and sliding speed depends on the contact geometry.
Optophoresis Accurately Predicts Response to Chemotherapy in CLL. (2004)

Abstract In vitro drug resistance assays have shown efficacy in predicting response to chemotherapeutic drugs in a number of solid tumors. In chronic lymphocytic leukemia (CLL) many assays are limited by the difficulty involved in culturing these cells ex vivo. We have developed a novel, optical-based methodology that is sensitive to broad cellular physical characteristics, such as morphology, size, refractive index, density and surface properties. This measurement, known as Optophoresis, quantifies cell motion induced by exposure to a moving optical gradient, generated from a near-infrared laser beam (Forster AH, et al. Anal Biochem 2004, 327(1):14–22 and Wang MM, et al. Appl Opt 2003, 42(28):5765–73). In Optophoresis small numbers of cells are analyzed intact, in their native state. No labels are required for quantification of functional responses, but cell subpopulations may be identified using fluorescent tags. We have used this assay to predict response to chemotherapeutic agents in patients with CLL. Methods: We performed Optophoresis with six drugs (fludarabine, chlorambucil, vincristine, cyclophosphamide, cladribine and prednisolone) on 74 CLL patient samples. 68 of these were classic B-CLL; there was one hairy cell variant, two were T-CLL, two evolved to PLL and one evolved to lymphoma. 21 of the samples were from patients for whom clinical data on response to chemotherapy was available for 33 drug treatments. Response to therapy was defined as a decrease in RAI stage. Results: 21 patients aged 58 to 93 years; 71% Rai stage III or IV were included in this analysis. Six patients were evaluated prospectively, with the assay performed before chemotherapy administration, and 15 patients were evaluated retrospectively with the assay performed after a course of treatment. Optophoresis accurately predicted response to chemotherapy in 88% of the 33 treatments evaluated. In the four instances for which the Optophoresis results did not match the retrospective clinical outcome; the patient was historically sensitive to treatment and Optophoresis results indicated current resistance to the drug. Subsequent resistance to drug therapy is known to occur in a significant percentage of treated CLL patients. Conclusion: Optophoresis of CLL cells accurately predicts response to chemotherapy in CLL. Further studies using results of Optophoresis to guide CLL treatment are warranted.
Synthesis and characterization of main-chain NLO oligomers and polymer that contain 4-dialkylamino- 4′-(alkylsulfonyl)azobenzene chromophores (2000)

An ω-amino carboxylic acid monomer that contained a nonlinear optical (NLO) chromophore was prepared by a convergent synthesis. Strategies for selective protection/deprotection of the amino and carboxylic acid functionalities were developed. The protected monomer, 4-[N-(4-benzyloxycarbonyl)butyl-N-methylamino]-4′-[2″,5″-bis(decyloxy)-4″-(phthalimidomethyl)benzylsulfonyl]azobenzene, could be deprotected selectively or sequentially to give HOOC-monomer-N-phthaloyl, benzyl-OOC-monomer-NH2, or HOOC-monomer-NH2. Sequential synthesis was performed to yield main-chain NLO dimers and tetramers. This was accomplished by selective deprotection and dicyclohexylcarbodiimide coupling. The HOOC-monomer-NH2 was polymerized by treatment with diphenylphosphoryl azide to give a main-chain NLO polyamide. The monomer, dimer, tetramer, and polymer NLO materials were characterized by 1H, 13C, IR, and UV–visible spectroscopy as well as by gel permeation chromatography, differential scanning calorimetry, and elemental analysis. The NLO properties of these materials were measured. Thin films of the oligomers and polymer were prepared by spin casting on indium-tin oxide coated glass. The second-order NLO properties of the oligomers and polymer thin films were studied by in situ corona poling/second-harmonic generation and attenuated total reflection methods. The optimal poling temperatures were significantly lower than the melting temperatures or glass-transition temperatures of the oligomers and polymer. The poling efficiency increased in the following order: monomer, oligomers, and polymer. An electro-optic coefficient of 4 pm/V at 1.06 μm was obtained for the polymer. © 2000 John Wiley & Sons, Inc.

Automated Defect Severity Analysis for Binary and PSM Mask Defects (2002)

Traditionally, mask defect analysis has been done through a visual inspection review. As the semiconductor industry moves into smaller process generations and the complexity of mask exponentially increases, the traditional mask defect analysis method becomes very time consuming. The Automatic Defect Severity Scoring (ADSS) module of i-Virtual Stepper System from Numerical Technologies offers an extremely fast and highly accurate software solution for defect printability analysis of advanced masks such as OPC and phase-shifting masks in a real production environment. In a previous paper [1], we have introduced the ADSS concept and discussed some results for line-space patterns on OPC and non-OPC masks. In this paper, we will discuss the ADSS results for both line-space and contact patterns on attenuated phase-shifting masks (ATTPSM), together with some ADSS results for line-space patterns on binary masks. The ADSS results are compared to wafer results. The wafer exposures were performed using 248 nm imaging technology and inspection images were generated on a KLA-Tencor’s SLF27 system.

In vivo evaluation of a Ti-based bulk metallic glass alloy bar (2015)

Ti-based bulk metallic glasses are reported with high strength, low Young modulus and high corrosion resistance, suggesting their potentials in biomedical applications. However a thorough in vivo evaluation of its biocompatibilities has not been conducted yet. In this study, we implanted bars of Ti-based bulk metallic glass in the femoral bone of rats, followed up local tissue reaction as well as its component ions' diffusion in local area and whole body. The Ti-based BMG (Ti40Zr10Cu34Pd14Sn2) alloy exhibited favorable features of both high strength and high elasticity. In vivo implant evaluation showed that it has a good tissue compatibility, equivalent bone integration and bonding ability with Ti sample. No component ion diffusion was detected up to 3 months post implantation. The possibility and efficacy of its use for bone implant is confirmed. Thus further long term implant study is recommended.
Flow Structure and Heat Transfer in Stagnation Flow CVD Reactor (2010)

An experimental study is undertaken to investigate the flow structure and heat transfer in a stagnation flow Chemical Vapor Deposition (CVD) reactor at atmospheric pressure. It is critical to develop models that predict flow patterns in such a reactor to achieve uniform deposition across the substrate. Free convection can negatively affect the gas flow as cold inlet gas impinges on the heated substrate, leading to vortices and disturbances in the normal flow path. This experimental research will be used to understand the buoyancy-induced and momentum-driven flow structure encountered in an impinging jet CVD reactor. Investigations are conducted for various operating and design parameters. A modified stagnation flow reactor is built where the height between the inlet and substrate is reduced when compared to a prototypical stagnation flow reactor. By operating such a reactor at certain Reynolds and Grashof numbers it is feasible to sustain smooth and vortex free flow at atmospheric pressure. The modified stagnation flow reactor is compared to other stagnation flow geometries with either a varied inlet length or varied heights between the inlet and substrate. Comparisons are made to understand the impact of such geometric changes on the flow structure and the thermal boundary layer. In addition, heat transfer correlations are obtained for the substrate temperature. Overall, the results obtained provide guidelines for curbing the effects of buoyancy and for improving the flow field to obtain greater film uniformity when operating a stagnation flow CVD reactor at atmospheric pressure.
Fast wave heating and current drive in tokamak plasmas with negative central shear (1996)

Fast waves provide an excellent tool for heating electrons and driving current in the central region of tokamak plasmas. In this paper, we report the use of centrally peaked electron heating and current drive to study transport in plasmas with negative central shear (NCS). Tokamak plasmas with NCS offer the potential of reduced energy transport and improved MHD stability properties, but will require non-inductive current drive to maintain the required current profiles. Fast waves, combined with neutral beam injection, provide the capability to change the central current density evolution and independently vary {ital T{sub e}}, and {ital T{sub i}} for transport studies in these plasmas. Electron heating also reduces the collisional heat exchange between electrons and ions and reduces the power deposition from neutral beams into electrons, thus improving the certainty in the estimate of the electron heating. The first part of this paper analyzes electron and ion heat transport in the L-mode phase of NCS plasmas as the current profile resistively evolves. The second part of the paper discusses the changes that occur in electron as well as ion energy transport in this phase of improved core confinement associated with NCS.

Switchable Motion of DNA on Solid Supports (2008)

Tracking the changes: The switchable translocation of a nucleic acid strand with a methylene blue (MB+) redox group on a DNA track associated with a surface can be triggered by adenosine monophosphate (AMP, green) and adenosine deaminase (purple, see picture); the latter converts AMP into inosine monophosphate (orange). The motion of the nucleic acid can be followed by the electrochemical, photo-electrochemical, and fluorescence signals.
<i>Plasmodium</i> Kinases As Targets For New-Generation Antimalarials (2012)

There is an urgent need for the development of new antimalarial drugs with novel modes of actions. The malarial parasite, Plasmodium falciparum, has a relatively small kinome of <100 kinases, with many members exhibiting a high degree of structural divergence from their host counterparts. A number of Plasmodium kinases have recently been shown by reverse genetics to be essential for various parts of the complex parasitic life cycle, and are thus genetically validated as potential targets. Implementation of mass spectrometry-based phosphoproteomics approaches has informed on key phospho-signalling pathways in the parasite. In addition, global phenotypic screens have revealed a large number of putative protein kinase inhibitors with antimalarial potency. Taken together, these investigations point to the Plasmodium kinome as a rich source of potential new targets. In this review, we highlight recent progress made towards this goal.

Ha-ras oncogene product in human gastric carcinoma: correlation with invasiveness, metastasis or prognosis. (1986)

c-Ha-ras oncogene product in human gastric carcinomas was examined by Western blotting and immunohistochemistry using anti-Ha-ras p21 antibody. In Western blotting, high levels of c-Ha-ras p21s were found in gastric carcinomas. Immunohistochemically, c-Ha-ras p21 was detected in 3 (11.1%) of 27 early carcinomas and in 63 (43.8%) of 144 advanced carcinomas. In advanced carcinomas, c-Ha-ras p21-immunoreactivity was correlated with the depth of tumor invasion and was stronger in metastatic tumors than in primary tumors. Patients with c-Ha-ras p21-positive carcinomas had a significantly worse prognosis than those with p21-negative carcinomas.
Effects of Intraventricular Infusions of Norepinephrine and Dopamine on LH Release and Ovulation in the Rabbit (1974)

The infusion of 50 µ g norepinephrine (NE) into the third ventricle of the brain was found to be highly effective in stimulating the release of an ovulatory surge of LH from the pituitary gland in estrogen-primed rabbits. Intraventricular dopamine (D), in dosages of 5 and 50 µ g, was not only completely ineffective in inducing ovulation, but the higher dosage actually blocked the ovulatory effect of NE, often for a month or more after infusion. In experimentts in which LH was measured by radioimmunoassay, intraventricular NE stimulated a marked rise in LH starting within minutes, peaking at 2 h and returning to pre-infusion levels by 6 h. No rise in serum LH was observed following the intraventricular infusion of D. Both dosages of D were quite effective in blocking LH output in response to NE infused 2 h later, and the 50-µ g dosage of D generally prevented any rise in serum LH concentration for some weeks after the infusion of intraventricular NE. The results are consistent with the hypothesis that a noradrenergic synapse is functional in hypothalamic mechanisms activating the release of pituitary LH.
Microbiological, immunological and genetic factors in family members with periodontitis as a manifestation of systemic disease, associated with hematological disorders (2002)

The microflora, immunological profiles of host defence functions, and human leukocyte antigen (HLA) findings are reported for a mother, son and daughter who were diagnosed as having 'periodontitis as a manifestation of systemic diseases, associated with hematological disorders'. Examinations were made of the bacterial flora from the periodontal pocket, neutrophil chemotaxis, neutrophil phagocytosis, and the genotypes (DQB1) and serotypes (DR locus) of HLA class II antigens. Phenotypic analyses of the peripheral lymphocytes were also conducted. The subgingival microflora from the mother was dominated by Gram-negative rods, especially Porphyromonas endodontalis, Prevotella intermedia/Prevotella nigrescens and Fusobacterium nucleatum. Subgingival microflora samples from the son and daughter were dominated by Gram-positive cocci and Gram-positive rods. Through the use of polymerase chain reaction, Campylobacter rectus and Capnocytophaga gingivalis were detected in all subjects, whereas Porphyromonas gingivalis, P. intermedia, and Treponema denticola were not detected in any subjects. All three subjects showed a remarkable level of depressed neutrophil chemotaxis to N-formyl-methionyl-leucyl-phenylalanine, although their phagocyte function levels were normal, in comparison to healthy control subjects. Each subject had the same genotype, HLA-DQB1*0601, while the mother had HLA-DR2 and HLA-DR8, and the son and daughter had HLA-DR2 only. In summary, the members of this family showed a similar predisposition to periodontitis with regard to certain host defence functions. It is suggested that the depressed neutrophil chemotaxis that was identified here could be a significant risk factor for periodontitis in this family.
Anisotropy in high angular resolution diffusion‐weighted MRI (2001)

The diffusion in voxels with multidirectional fibers can be quite complicated and not necessarily well characterized by the standard diffusion tensor model. High angular resolution diffusion-weighted acquisitions have recently been proposed as a method to investigate such voxels, but the reconstruction methods proposed require sophisticated estimation schemes. We present here a simple algorithm for the identification of diffusion anisotropy based upon the variance of the estimated apparent diffusion coefficient (ADC) as a function of measurement direction. The rationale for this method is discussed, and results in normal human subjects acquired with a novel diffusion-weighted stimulated-echo spiral acquisition are presented which distinguish areas of anisotropy that are not apparent in the relative anisotropy maps derived from the standard diffusion tensor model.

Microbial Degradation of Natural Rubber Vulcanizates (1985)

An actinomycete, Nocardia sp. strain 835A, grows well on unvulcanized natural rubber and synthetic isoprene rubber, but not on other types of synthetic rubber. Not only unvulcanized but also various kinds of vulcanized natural rubber products were more or less utilized by the organism as the sole source of carbon and energy. The thin film from a latex glove was rapidly degraded, and the weight loss reached 75% after a 2-week cultivation period. Oligomers with molecular weights from 10 to 10 were accumulated during microbial growth on the latex glove. The partially purified oligomers were examined by infrared and H nuclear magnetic resonance and C nuclear magnetic resonance spectroscopy, and the spectra were those expected of cis-1, 4-polyisoprene with the structure, OHC-CH(2)-[-CH(2)-C(-CH(3))=CH -CH(2)-](n)-CH(2)-C(=O)- CH(3), with average values of n of about 114 and 19 for the two oligomers.
Measurement of aqueous foam rheology by acoustic levitation (2000)

An experimental technique is demonstrated for acoustically levitating aqueous foam drops and exciting their spheroidal modes. This allows fundamental studies of foam-drop dynamics that provide an alternative means of estimating the viscoelastic properties of the foam. One unique advantage of the technique is the lack of interactions between the foam and container surfaces, which must be accounted for in other techniques. Results are presented in which a foam drop with gas volume fraction $\ensuremath{\varphi}=0.77$ is levitated at 30 kHz and excited into its first quadrupole resonance at $63\ifmmode\pm\else\textpm\fi{}3 \mathrm{Hz}.$ By modeling the drop as an elastic sphere, the shear modulus of the foam was estimated at $75\ifmmode\pm\else\textpm\fi{}3 \mathrm{Pa}.$
