Return path for interactive TV using white spaces: A novel application for 802.22 WRAN (2011)

Interactive TV capitalizes on the opportunities created by digitisation to offer new services. Depending on the level of interactivity, a return path is required to send data from the home user back to the broadcaster. In this paper, we propose the use of 802.22 WRAN to implement the return path over white spaces. Our approach allows the transmission of interactive data in overlay with broadcast data. Following 802.22's requirements, we analyze the task of selecting settings for cooperative spectrum sensing. First, our numerical results show that the number of cooperative devices used to improve sensing accuracy is constrained to the minimum data rate per device. Second, we show through computer simulations that noise uncertainty limits cooperation gains regardless of how settings are selected. Wrapping up our analysis, real-world conditions are considered through testbed experimentation. Measurements confirm that maximum diversity cannot be achieved under correlated shadowing but cooperation may bring advantages if a subset of cooperative devices malfunctions. To the best of our knowledge, this is the first study on the application of 802.22 WRAN as access technology for return paths of interactive TV.
Bifunctional Catalysis by CDP-ribitol Synthase:  Convergent Recruitment of Reductase and Cytidylyltransferase Activities in Haemophilus influenzae and Staphylococcus aureus (2004)

CDP-ribitol synthase catalyzes the formation of CDP-ribitol from ribulose 5-phosphate, NADPH, and CTP. CDP-ribitol is an activated precursor for the synthesis of virulence-associated polysaccharides in the capsule of the Gram-negative pathogen Haemophilus influenzae and in the cell walls of Gram-positive pathogens including Staphylococcus aureus. We showed previously that CDP-ribitol synthase activity in H. influenzae is catalyzed by the bifunctional enzyme Bcs1 in a two-step reaction with reduction preceding cytidylyl transfer [Zolli, M., et al. (2001) Biochemistry 40, 5041-5048]. In the work reported here, we predicted a CDP-ribitol synthesis locus in S. aureus tandemly arranged as tarI, encoding an orthologue of the cytidylyltransferase domain of Bcs1, and tarJ, coding for an analogue of the reductase domain of Bcs1. We have shown the formation of a functional CDP-ribitol synthase complex between TarI and TarJ. Steady-state mechanistic studies of the CDP-ribitol synthases TarIJ and Bcs1 revealed that the analogous reductases and orthologous cytidylyltransferases undergo ordered mechanisms. The sequence of substrate binding and product release of the orthologous cytidylyltransferases differed. Steady-state analysis of the reductase and cytidylyltransferase activities of TarIJ indicated a 100-fold difference in the turnover where the primary reductase was rate limiting. Rapid mixing experiments revealed the presence of approximately 12 microM ribitol 5-phosphate at steady state, 100-fold lower than the observed K(m) for this intermediate. Analysis of the approach to steady state suggested that channeling was not occurring in the coupled enzyme complex and was an unlikely driving force in the convergent recruitment of reductase and cytidylyltransferase activities in the two CDP-ribitol synthases.
Choice of latent explanatory variables: a multiobjective optimization approach (2000)

A multiobjective, optimization-based approach for finding latent explanatory variables for linear models is presented. The best choice of a set of latent explanatory variables is made by minimizing a user-specified combination of criteria. In this paper, three criteria are used: (i) the data matrix-related residue, (ii) the observation- or measurement-related residue and (iii) the condition number of the new data matrix of the latent explanatory variables. Successful application of the proposed technique toward identification of a multivariable pilot-scale plant is presented. The proposed algorithm is compared with the well-known PLS algorithm, and the result shows that the proposed algorithm is better than the PLS algorithm. Copyright © 2000 John Wiley & Sons, Ltd.
ClpV, a unique Hsp100/Clp member of pathogenic proteobacteria (2005)

Hsp100/Clp proteins are key players in the protein quality control network of prokaryotic cells and function in the degradation and refolding of misfolded or aggregated proteins. Here we report the identification of a new class of Hsp100/Clp proteins, termed ClpV (virulent strain), that are present in bacteria interacting with eukaryotic cells, including human pathogens. The ClpV proteins are most similar to ClpB proteins within the Hsp100/Clp family, but cluster in a separate phylogenetic tree with a remarkable distance to ClpB. ClpV representatives from Salmonella typhimurium and enteropathogenic Escherichia coli form oligomeric assemblies and display ATP hydrolysis rates comparable to ClpB. However, unlike ClpB, both ClpV proteins failed to solubilize aggregated proteins. This lack of disaggregation activity correlated with the inability of ClpB model substrates to stimulate the ATPase activity of ClpV proteins, indicating differences in substrate selection. Furthermore, we show that clpV genes are generally organized in a conserved gene cluster, encoding a potential secretion system, and we demonstrate that increased levels of a dominant negative variant of either S. typhimurium or Yersinia pseudotuberculosis ClpV strongly reduce the ability of these pathogenic bacteria to invade epithelial cells. We propose a role of this novel and unique class of AAA+ proteins in bacteria-host cell interactions.
Aplicación de la Cromatografía de Gases Bidimensional en el Análisis de Derivados Azufrados y Nitrogenados en Gasolina (2010)

The comprehensive two-dimensional gas chromatography (GC×GC) is used as a powerful tool for an improved characterization in sulphur and nitrogen speciation in gasoline.There are shown the results obtained of the connection between GC×GC and a specific detector, sulphur (SCD) and Nitrogen (NCD).This technique is based on the separation of two orthogonal dimensions, achieved by two chromatographic capillary columns with different polarity.The final chromatogram obtained was structured according to the volatility and polarity of hydrocarbons which facilitates its identification.The results are a very promising alternative in the characterization of these types of compounds in middle distillates.This work illustrates the high resolution power of the GC×GC in combination with a selective detection of sulphur or nitrogen compounds in gasoline when a specific detector is used.
Pump-Probe Imaging of Integrated Circuits (2013)

Abstract We present a new method of imaging integrated circuits (ICs) using a dual-laser scanning confocal microscope. In this method we introduce physical and/or functional changes to the integrated circuit using the first ‘pump’ laser and then image the response of the circuit using the second ‘probe’ laser. We propose several novel applications of this imaging method. Specifically, we show how to image the flow of injected charge carriers and use the derived images to improve the resolution of material interfaces. We also show how to image changes to activity and laser voltage-probed waveforms and use the information to discover electrical connections between logic cells.
Solar and Thermal Energy Harvesting Textile Composites for Aerospace Applications (2012)

Abstract : The overall goal of the project was to design and demonstrate fiber-based energy harvesting devices that can convert light and heat to electricity, and be integrated into air vehicle structures. Specifically, in Year 1, we set out to design and demonstrate photovoltaic and thermoelectric devices on polymer fibers. In Years 2 and 3, we sought to improve the performance of individual energy converting fibers, as well as to develop models and device architectures that would produce significant gains when many fibers are aggregated. We have successfully demonstrated thermoelectric (TE) and photovoltaic (PV) fibers, achieved substantial improvements in the power conversion efficiency, and developed and validated ro-bust, predictive models for both OPV and TE fibers. Additionally, we developed optics-based approaches to tuning the sensitivity bands of photodetectors, and improving light in-coupling in solar cells and pho-todetectors. Encouraged by these advances, we have begun the design and construction of a novel appa-ratus for reel-to-reel coating and encapsulation of active devices on fibers, financed in large part by an AFOSR DURIP grant. We are also actively exploring options for creating a start-up company specializ-ing in multi-functional, energy conversion devices based on the technology developed during this project.
Noninvasive Ventilation and Weaning in Patients with Chronic Hypercapnic Respiratory Failure: A Randomized Multicenter Trial (2011)

No difference was found in the reintubation rate between the three weaning strategies. NIV decreases the intubation duration and may improve the weaning results in difficult-to-wean patients with CHRF by reducing the risk of postextubation ARF. The benefit of rescue NIV in these patients deserves confirmation.
LUNG FUNCTION TESTS AND ITS CLINICAL APPLICATION (1978)

呼吸器疾患は過去20年間に結核症の著しい減少と相まつて,疾病も著しく多岐にわたり,その病態も多彩を極め,人をとりまく環境の変遷とも関連して複雑な様相を示すに至つている.これに対応して,呼吸器疾患の診断,病態の把握,予後の決定,治療の適応ならびに経過観察に,呼吸機能検査はrespirologyの中枢をなし,重要不可欠な役割を果しつつある,また呼吸器疾患のみならず,心,脳,さらには,消化器など他臓器における疾病の診断,治療に同様に重要な地位を占めつつある.本論文においては,慢性閉塞性肺疾患,肺線維症を中心とした呼吸器疾患の臨床における呼吸機能検査の役割について述ベ,ことに近年とみに進展をみせているsmall airway領域の疾病を対象とした新しい検査法の役割を,われわれが近年開発した検査法を紹介しながら解説した,その主なものは,フローボリウム,クロージングボリウム,動肺コンプライアンス,気道の過敏性自動判別装置,胸郭運動測定装置などである.一方ガス交換機能については,ことにCO肺拡散能力についてその意義,形態と機能との関係についても論及した.今後,呼吸機能検査はますます複雑化し,したがつてそれらを統合する自動化への道を進むと思われるが,将来の展望としては,被検者の努力を要しない,より客観性の高い検査法の確立と,それによる自動診断の確立が緊急を要する研究課題と考えられる.
Serum zinc, copper, and the Cu/Zn ratio in patients with benign and malignant breast lesions (1980)

Serum zinc, copper, and the Cu/Zn ratio were evaluated in 80 patients with breast lesions prior to surgery. There were 37 patients with benign and 43 with malignant breast lesions. There was no evidence of weight loss, impaired appetite, or change in eating pattern in any of the patients. There was a statistically significant difference for the mean SCL and Cu/Zn ratio between controls, age 66-94, and patients with malignant breast lesions. This difference was also observed between the ages of 20-45 and 66-94 among controls, suggesting that this is age related rather than disease related. The range of distribution for SZL and SCL were similar for all groups studied. Neither SZL, SCL, or the Cu/Zn ratio were of value in discriminating between controls and patients with benign or malignant breast lesions. We were unable to demonstrate the value of these parameters as markers of disease activity in patient with benign or malignant breast lesions.
Hiv‐associated Hodgkin disease: A clinical study of 18 cases and review of the literature (1991)

Intermediate- and high-grade B-cell non-Hodgkin lymphoma (NHL) occurring in a human immunodeficiency virus (HIV)-infected patient is considered diagnostic of the acquired immunodeficiency syndrome (AIDS). Other neoplasms (both hematopoietic and nonhematopoietic) have also been reported in patients with HIV infection, although none except Kaposi sarcoma carries the same diagnosis of AIDS as B-cell NHL in an HIV-infected host. There have been previous reports in the literature of Hodgkin disease (HD) in HIV-infected patients. We describe our clinical and pathological experience with HD from 1984-1989, in 18 patients with documented HIV infection and also review the literature on HD in HIV-infected patients. Almost all patients described herein presented with advanced disease and mixed cellularity histology and did very poorly despite some good initial responses to therapy. By statistical analysis, we found that the patients with HIV-associated HD had a strong tendency to be outside the age range seen in non-HIV-associated HD (P less than 0.005). We also discuss the possible relationship between HIV and HD and consider whether HIV-associated HD, like B-cell NHL, is a manifestation of AIDS.
Rheological and mechanical study of micro-nano sized biocarbon-PLA biodegradable biocomposites (2023)

Pinewood sawdust was pyrolyzed to create a micro-nanocarbon. The adsorbent’s particle size was reduced during a ball milling procedure to improve the surface area and encourage porosity growth. The synergistic effects of micro-nano-adsorbent-reinforced poly(lactic acid) (PLA) composites were investigated by analyzing the efficiency of the rheological process. The properties of the prepared composites also were examined using various characterization tests, including tensile and hardness tests, crystallinity tests, elemental composition, and plasticity behavior tests. Therefore, in-depth investigations and comparisons were also carried out to confirm the created composites’ efficacy compared to other outcomes.
Mobile telephony based secured society an anti-terrorism attempt (2008)

In this paper a novel mechanism for explosive trace detection in any populated area by the use of mobile telephony has been described. The aim is to create a system that will assure common men, local population and above all the nation a secured environment, without disturbing their freedom of movement. It would further help the police in detection of explosives more quickly, isolation of suicide bombers, remediation of explosives manufacturing sites, and forensic and criminal investigation. To achieve this, the paper has projected an idea which can combine the strength of the mobile phones, the polymer sensor and a standard called explosive tracing mobile technology directive (ETMTD) together to form a system called explosive trace detection system (ETDS). The reason for using mobile phone is that it is the most accepted electronic device the world has ever produced, has the largest network, extremely high usage and distributed over a large geography. ETMTD is similar to waste electrical and electronic equipment directive (WEEE) or the European law. The system is capable of detecting explosives within a defined territory. It would communicate the location of the detected explosives to the respective service provider, which in turn would inform the law and enforcement agency or police. ETMTD would enforce the communication without intervention of the user as well as the service provider.
Rat Hepatocyte Cultures: Conventional Monolayer Cultures and Cocultures with Rat liver Epithelial Cells (2003)

Primary cultures of hepatocytes are useful tools for both short- and long-term pharmacotoxicological research. Under conventional conditions, isolated hepatocytes form a monolayer and survive for about 1 wk but lose some liver-specific functions, including xenobiotic biotransformation. In comparison with the conventional monolayer culture model, cocultures with rat liver epithelial cells (RLECs) have an extended life-span and better maintain their drug-metabolizing capacity, owing to the presence of cell-cell interactions. In this chapter, techniques for setting up conventional monolayer cultures and cocultures of hepatocytes with RLECs (including isolation, culture, and cryopreservation of RLECs) are described in detail. In addition, comments derived from our own experience are given for successfully culturing primary hepatocytes.
A 94,OOO-Dalton Glycoprotein Expressed by Human Melanomaand Carcinoma Cells<xref ref-type="fn" rid="fn2">2</xref> (1982)

The IgG2a monoclonal antibody (MoAb) 376.96S, secreted by a hybridoma derived from a mouse immunized with cultured human melanoma cells COLO 38, reacts with a single 94,000-dalton glycoprotein that is peripherally associated with the plasma cell membrane of cultured melanoma cells. Indirect immunofluorescence analysis with cryostat thin sections of human tissues showed that this antigen is absent from a large variety of normal tissues but is readily detectable on melanomas, nevi, and several different carcinomas. The MoAb 376.96S binds with cultured melanoma and carcinoma cell lines to a similar extent and can mediate both complement-dependent and cell-dependent lysis of these cells. The 94,000-dalton glycoprotein detected by MoAb 376.96S is distinct in its tissue distribution, antigenicity, and molecular profile from several structures previously identified with monoclonal antibodies that have similar molecular weights.
Instrumentation in Support of Research on Bio-optical Thin Layers in Coastal Waters (1997)

Abstract : My long term goal is to understand the functional roles of microzooplankton (20-200 microns) in the sea. It has been argued that on a timescale of days, the instantaneous grazing rate of zooplankton in toto is greater than the instantaneous rates of vertical and horizontal mixing by at least an order of magnitude, and is the same order of magnitude as the instantaneous rate of phytoplankton cell division. Hence, grazing is a critically important loss term in phytoplankton dynamics (Banse, 1992). Because microzooplankton are the major grazers of phytoplankton in pelagic food webs under most circumstances, their grazing impacts exert an important impact on phytoplankton losses in the sea. My specific interests are in the vital rate processes of feeding and reproduction (e.g., Gifford 1988; Gifford, et al. 1995) and in understanding their function as prey for higher organisms (e.g., Gifford and Dagg, 1988; Gifford 1993).
Anti-Colorectal Cancer Effects of Probiotic-Derived p8 Protein (2019)

Recently, we reported a novel therapeutic probiotic-derived protein, p8, which has anti-colorectal cancer (anti-CRC) properties. In vitro experiments using a CRC cell line (DLD-1), anti-proliferation activity (about 20%) did not improve after increasing the dose of recombinant-p8 (r-p8) to >10 μM. Here, we show that this was due to the low penetrative efficiency of r-p8 exogenous treatment. Furthermore, we found that r-p8 entered the cytosol through endocytosis, which might be a reason for the low penetration efficiency. Therefore, to improve the therapeutic efficacy of p8, we tried to improve delivery to CRC cells. This resulted in endogenous expression of p8 and increased the anti-proliferative effects by up to 2-fold compared with the exogenous treatment (40 μM). Anti-migration activity also increased markedly. Furthermore, we found that the anti-proliferation activity of p8 was mediated by inhibition of the p53-p21-Cyclin B1/Cdk1 signal pathway, resulting in growth arrest at the G<sub>2</sub> phase of the cell cycle. Taken together, these results suggest that p8 is toxic to cancer cells, shows stable expression within cells, and shows strong cancer suppressive activity by inducing cell cycle arrest. Therefore, p8 is a strong candidate for gene therapy if it can be loaded onto cancer-specific viruses.
Photoinduced Intersubband Absorption and Enhanced Photobleaching in Twisted Bilayer Graphene (2020)

High-sensitivity femtosecond microscopy with broad spectral coverage reveals photoinduced intersubband absorption and enhanced photobleaching bands in twisted bilayer graphene endowed with picosecond relaxation time and twist angle-tunable energy position.
Differential ray tracing in inhomogeneous media (1997)

Differential ray tracing determines an optical system's first-order properties by finding the first-order changes in the configuration of an exiting ray in terms of changes in that ray's initial configuration. When one or more of the elements of a system is inhomogeneous, the only established procedure for carrying out a first-order analysis of a general ray uses relatively inefficient finite differences. To trace a ray through an inhomogeneous medium, one must, in general, numerically integrate an ordinary differential equation, and Runge–Kutta schemes are well suited to this application. We present an extension of standard Runge–Kutta schemes that gives exact derivatives of the numerically approximated rays.
The effect of protein and lipid source in organic feed for (organic) rainbow trout on sensory quality (2011)

The aim of this work was to study which effects protein and lipid source in feed for organic rainbow trout (Oncohynchus mykiss) may have on the sensory quality of the final product after up to 14 days of storage in ice. The protein sources used in the experiment were fishmeal and a mixture of vegetable protein. While the lipid sources were fish, linseed, sunflower, rapeseed and grape seed oil. After slaughtering all fish were frozen (-40°C) until the sensory experiment was performed, for which the trout were thawed and stored for 3, 5, 7 and 14 days in ice respectively. The sensory experiment included objective sensory profiling, of samples which were heat treated in a convention oven at 100°C until the core temperature was 70°C. The sensory panel consisted of 11 assessors which all were tested and trained. The sensory analysis included descriptors related to the odour, appearance, flavour and texture. After 3 days of storage in ice an impact of lipid source is seen. Inclusion of linseed oil resulted in a sensory profile comparable to the use of fish oil in the feed. While some of the other vegetable oils, especially grape seed oil results in a sensory profile rather different from the trout that had fish oil. However, this difference observed after 3 days of storage did not appear after a longer storage time, and consequently no differences in the sensory characteristics is observed after the 5 days of storage in ice. Nevertheless after 7 days in ice some differences are appearing again. Here the trout which have had rapeseed and grape seed oil in the feed has a more neutral flavour and odour compared to the other ones. After 14 days of storage the protein source had an effect, and the trout which received fishmeal in the feed were more tainted. Therefore, it is seen that the shelf-life is increased by feeding the fish with vegetable protein compared to fish meal. The conclusion of the experiment therefore was that both dietary vegetable protein and lipid sources can influence on sensory characteristics of trout stored in ice.
