The biosynthetic pathway of sulfur-containing molecules in Human Axillary Malodor: from precursors to odorous volatiles (2009)

A côté des stéroïdes et des acides gras, une troisième classe de molécules ayant un seuil de perception très faible, les sulfanylakanoles, contribuent à l'odeur caractéristique de la transpiration humaine. Ce travail de thèse a permis l'identification de la bactérie S. haemolyticus, comme capable de générer le (R) et le (S)-3-methyle-3-sulfanylhexan-1-ole (forme majoritaire, ayant une odeur d'oignon) après incubation avec un conjugué de la cystéine et de la glycine présent dans les secrétions axillaires. Les enzymes de S. haemolyticus issues du gene metC tel que la cytathionine β-lyase ont peu d'implication dans cette transformation. Etonnamment, le ratio entre la concentration des précurseurs acides (conjugés de la glutamine) et des précurseurs soufrés est trois fois plus important chez l'homme que chez la femme. Des analyses sensorielles ont confirmé le caractère essentiel de la composition de la sueur sur le développement des odeurs corporelles qui sont ensuite modulées par la flore cutanée.
Intracellular localization of fibronectin using immunoperoxidase cytochemistry in light and electron microscopy. (1980)

An immunocytochemical staining method for light and electron microscopy was developed to permit adequate penetration of staining conjugates with high specificity, while preserving acceptable ultrastructure. For this purpose an indirect immunoperoxidase method with Staphylococcal protein A-peroxidase conjugates was used in the presence of saponin on aldehyde-saponin-fixed cells. As the first application, fibronectin was localized intracellularly in human embryonic skin fibroblasts. Fibronectin was detected in large amounts in the cisternae of rough endoplasmic reticulum and in 200 nm (secretory?) vesicles. Little fibronectin was present in the Golgi complex; the stacked Golgi cisternae were conspicuously devoid of this protein. The 200 nm vesicles were mostly distributed on the mature side of the Golgi apparatus. These results indicate that fibronectin is exclusively localized to intracellular structures involved in secretory function and suggest that fibronectin may not be processed in significant amounts within the cisternal stacks of the Golgi complex.
An update on the penetration depth of 630 nm light in normal and malignant human brain tissue in vivo (1986)

In a recent paper (Wilson et al. ibid., vol.31, p.125-33, 1986) the authors described measurements of the effective penetration depth of 630 nm light in brain tissue, which were carried out in two patients receiving intra-operative photodynamic therapy for malignant brain tumours. Here, they present the results of further measurements on a total of eight patients using the same technique. For these studies they have, as far as possible, grouped the data according to whether the tissues measured were mainly normal cerebral brain tissue, mainly, malignant astrocytic tumour tissue or a mixture of normal and tumour tissues. This has enabled more direct comparison with published in vitro measurements of human brain tumour tissues (Svaasand and Ellingsen, Photo Chem. Photobiol., vol.38, p.293-9, 1983, Photochem. Photobiol., vol.41, p.73-6, 1985).
An integrated 5.2GHz CMOS T/R switch with LC-tuned substrate bias (2003)

A 0.56mm/sup 2/ T/R switch in 0.18/spl mu/m CMOS achieves 1.5dB insertion loss, 28dBm P/sub 1cB/, 30dB isolation and 4kV HBM ESD rating. The switch uses an on-chip LC-tuned substrate biasing technique to enhance linearity and allows the LNA and PA to be matched independently. Power dissipation is 30/spl mu/W.
Patent Update Oncologic, Endocrine & Metabolic: Oncologic, Endocrine & Metabolic: Inhibitors of protein farnesylation (1996)

In this article, we update the progress reported towards developing an inhibitor of protein farmesyltransferase (PFTase) as a new type of cancer therapy. For the rationale behind this undertaking, please refer to the review published in this journal in December 1995 [1], and other reviews [2,3]. A few experiments bearing on the utility of PFTase inhibitors as antitumour agents are considered first, including biological results obtained with compounds described in our earlier review. Finally, new compounds described in the scientific and patent literature in the past year are reported. As in the previous review, these are grouped according to their kinetic mechanism of inhibition of PFTase.
Shaving Peaks by Augmenting the Dependency Graph (2019)

Demand Side Management (DSM) is an important building block for future energy systems, since it mitigates the non-dispatchable, fluctuating power generation of renewables. For centralized DSM to be implemented on a large scale, considerable amounts of electrical demands must be scheduled rapidly with high time resolution. To this end, we present the Scheduling With Augmented Graphs (SWAG) heuristic. SWAG uses simple, efficient graph operations on a job dependency graph to optimize schedules with a peak shaving objective. The graph-based approach makes it independent of the time resolution and incorporates job dependencies in a natural way. In a detailed evaluation of the algorithm, SWAG is compared to optimal solutions computed by a mixed-integer program. A comparison of SWAG to another state-of-the-art heuristic on a set of instances based on real-word consumption data demonstrates that SWAG outperforms this competitor, in particular on hard instances.

Development of passive electronic components for instrumentation of improved geothermal logging tools and components. Annual progress report (1977)

Short term objectives for well-logging instrumentation are circuits which can operate at temperatures in the range 275/sup 0/C to 350/sup 0/C; the medium term goal is operation up to 500/sup 0/C, and the long term goal is to achieve operation at 1000/sup 0/C. It is apparent that useful electronic circuits will require the combination of both passive components and active devices. In order to meet the compatibility requirements, the basic technology which has been selected in this project is the chemical vapor deposition of metal interconnections, resistor material, dielectric material and passivating material. It is to be emphasized that this is a thin-film, not thick-film, technology which is compatible with the processing methods used in fabricating either semiconductor or integrated thermionic devices, and produces components which are electrically compatible with those devices. The investigation in this project is primarily directed toward tungsten metallization, tungsten-silicon resistors, and silicon nitride dielectric and passivation.
Stochastic Chase Decoding of Reed-Solomon Codes (2010)

In this letter, we propose a probabilistic approach to the generation of test patterns in the Chase Algorithm (CA) denoted as the Stochastic Chase Algorithm (SCA). We compare the performance of SCA with the regular CA for different Reed-Solomon codes. Simulation results show that the probabilistic nature of the SCA helps in providing a more efficient test pattern generation. SCA avoids the use of least reliable bits selection and reduces the number of candidate codewords up to 60% for the same decoding performance.
Ultra Precision Positioning using Air Bearing Lead Screw. (2000)

In order to realize positioning of nano-meter precision, it is important to eliminate friction and backlash from mechanical parts making relative sliding and/or rolling motion. This paper first describes the principle of an Air Bearing Lead Screw(ABLS)in which the lead screw surface is completely separated from the nut surface by the pressured air film. Then a positioning system comprised of ABLS, a table, an air guideway and air bearings used for supporting the screw shaft is introduced. The system is free from friction except that by DC motor brushes. The basic dynamic characteristics of the system are examined and some controllers are designed and implemented. Experimental results show that the system can position the table with the accuracy of a few nano-meters.
Analysis of Smear Noise in Interline-CCD Image Sensor with Gate-Free Isolation Structure (1991)

A gate-free isolation structure for smear noise suppression is proposed for an interline transfer charge-coupled device (IL CCD) image sensor. Analysis of the smear components shows that the signal-to-smear ratio in the proposed structure is 30 dB larger than that in a conventional structure, and is comparable to those of frame interline transfer (FIT) CCDs, while the isolation and breakdown characteristics of the proposed structure are similar to those of the conventional structure. These results indicate that the high-definition interline-CCD image sensors are promising for HDTV applications.
The relationship between functional status and judgment/problem solving among individuals with dementia (2012)

Among individuals with a diagnosis of dementia, declining functional status as well as declining cognition should raise concerns about judgment/problem solving.
Early overexpression of cyclin D1 protein in mouse skin carcinogenesis (1995)

Abnormal expression of cell-cycle regulatory proteins, particularly cyclin D1, has been described in human cancers. However, there are few reports of this kind in experimental carcinogenesis models, which provide a framework to analyze the importance of those alterations in early cancer development. Previous studies from our laboratory showed that cyclin D1 mRNA was overexpressed in skin tumors generated in SENCAR mice by a two-stage carcinogenesis protocol. In the study presented here, immunoprecipitation of fresh tumor samples confirmed the overexpression of cyclin D1 protein. We also developed an immunohistochemical technique to determine which cells in the lesions overexpressed the cyclin and the timing of deregulation during cancer development. Surprisingly, we found that all premalignant lesions, including small incipient papillomas, overexpressed cyclin D1, whereas normal and hyperproliferative skin were negative. Nuclear immunostaining was detected only in the proliferative compartments of the tumors and showed an apparent cell-cycle-related variation. These results provide evidence for a role of cyclin D1 overexpression in mouse skin carcinogenesis and support the use of this model as an alternative to in vitro studies to help understand the involvement of cyclin deregulation in cancer development.
Effects of Ionic Liquid Molecules in Hybrid PbS Quantum Dot–Organic Solar Cells (2013)

We investigated the effect of ionic liquid molecules (ILMs) in hybrid quantum dot-organic solar cells (HyQD-OSCs). The insertion of an ILM layer between PbS and phenyl-C61-butyric acid methyl ester (PCBM) can shift the band edge of PCBM closer to the vacuum level of PbS due to spontaneous dipole polarization. Because of this new architecture, improvements in device performance were achieved, including increases in open-circuit voltage (VOC, from 0.41 V to 0.49 V), fill factor (FF, from 0.48 to 0.59), and power conversion efficiency (PCE, from 1.62% to 2.21%), compared to reference devices under AM 1.5G illumination at 100 mW cm(-2). We observed that treatment of the PbS layer with ILMs causes a significant increase in work function from 3.58 eV to 3.93 eV. Furthermore, the ILMs layer minimizes the contact resistance between PbS and PCBM due to the improved compatibility between the two layers, confirmed as a decrease in charge transfer resistance, as measured by electrical impedance spectroscopy.
Bibliography of work on the photocatalytic removal of hazardous compounds from water and air (1994)

This is a bibliography of information in the open literature on work that has been done to date on the photocatalytic oxidation of compounds, principally organic compounds. The goal of the listing is removing hazardous oompounds from water or air. It contains lists of substances and literature citations. The bibliography includes information obtained through the middle of 1993 and some selected references for the balance of that year.
A compact saliency model for video-rate implementation (2011)

Salient regions are useful for priority processing of fixated areas in case of limited computational or bandwidth resources. This paper presents an efficient and compact saliency model, compatible with image sensors implementation. In contrast with Itti's reference model, our model relies on a low-complexity processing consisting of inter-frame difference, spatial contrast, and the central fixation bias. Simple weighted combinations of these factors show better results than Itti's model. Moreover, a combination using time-varying weights further improves the performance; and results show that spatial saliency should be integrated after motion saliency. Besides, a new criterion compatible with image sensors is used to evaluate the models.
Postpartum Remodeling, Lactation, and Breast Cancer Risk: Summary of a National Cancer Institute–Sponsored Workshop (2012)

The pregnancy-lactation cycle (PLC) is a period in which the breast is transformed from a less-developed, nonfunctional organ into a mature, milk-producing gland that has evolved to meet the nutritional, developmental, and immune protection needs of the newborn. Cessation of lactation initiates a process whereby the breast reverts to a resting state until the next pregnancy. Changes during this period permanently alter the morphology and molecular characteristics of the breast (molecular histology) and produce important, yet poorly understood, effects on breast cancer risk. To provide a state-of-the-science summary of this topic, the National Cancer Institute invited a multidisciplinary group of experts to participate in a workshop in Rockville, Maryland, on March 2, 2012. Topics discussed included: 1) the epidemiology of the PLC in relation to breast cancer risk, 2) breast milk as a biospecimen for molecular epidemiological and translational research, and 3) use of animal models to gain mechanistic insights into the effects of the PLC on breast carcinogenesis. This report summarizes conclusions of the workshop, proposes avenues for future research on the PLC and its relationship with breast cancer risk, and identifies opportunities to translate this knowledge to improve breast cancer outcomes.
Trajectory Convolution for Action Recognition (2018)

How to leverage the temporal dimension is a key question in video analysis. Recent works suggest an efficient approach to video feature learning, i.e., factorizing 3D convolutions into separate components respectively for spatial and temporal convolutions. The temporal convolution, however, comes with an implicit assumption – the feature maps across time steps are well aligned so that the features at the same locations can be aggregated. This assumption may be overly strong in practical applications, especially in action recognition where the motion serves as a crucial cue. In this work, we propose a new CNN architecture TrajectoryNet, which incorporates trajectory convolution, a new operation for integrating features along the temporal dimension, to replace the existing temporal convolution. This operation explicitly takes into account the changes in contents caused by deformation or motion, allowing the visual features to be aggregated along the the motion paths, trajectories. On two large-scale action recognition datasets, namely, Something-Something and Kinetics, the proposed network architecture achieves notable improvement over strong baselines.
Two-Handed Through-the-Lens-Techniques for Navigation in Virtual Environments (2001)

We present a tool set of techniques for navigation in virtual environments. Based on a through-the-lens concept, the user is enabled to simultaneously view the surrounding virtual world and an arbitrary location of the virtual world as seen through an interactively defined window. For the manipulation and the adjustment of this virtual window we propose three different strategies, loosely based on the well-known eyeball-in-hand, scene-in-hand, and world-in-miniature techniques. Since our technique provides a preview area with controllable size and position, the occluded part of the scene can be flexibly managed, while enabling intuitive and precise work with the proposed tools. The proposed techniques provide powerful tools that are easy to implement and can be applied in any type of virtual environments.
Bioinformatic identification of novel putative photoreceptor specific cis-elements (2007)

We predict novel, putative cis-elements enriched in the promoter of rod-specific or cone-specific genes. These are candidate binding sites for transcription factors involved in maintaining functional differences between rod and cone photoreceptor populations.
Deterministically maximizing feasible subsystem for robust model fitting with unit norm constraint (2011)

Many computer vision problems can be accounted for or properly approximated by linearity, and the robust model fitting (parameter estimation) problem in presence of outliers is actually to find the Maximum Feasible Subsystem (MaxFS) of a set of infeasible linear constraints. We propose a deterministic branch and bound method to solve the MaxFS problem with guaranteed global optimality. It can be used in a wide class of computer vision problems, in which the model variables are subject to the unit norm constraint. In contrast to the convex and concave relaxations in existing works, we introduce a piecewise linear relaxation to build very tight under- and over-estimators for square terms by partitioning variable bounds into smaller segments. Based on this novel relaxation technique, our branch and bound method can converge in a few iterations. For homogeneous linear systems, which correspond to some quasi-convex problems based on L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> -L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> -norm, our method is non-iterative and certainly reaches the globally optimal solution at the root node by partitioning each variable range into two segments with equal length. Throughout this work, we rely on the so-called Big-M method, and successfully avoid potential numerical problems by exploiting proper parametrization and problem structure. Experimental results demonstrate the stability and efficiency of our proposed method.

Complete primary structure of human collagen alpha 1 (V) chain (1991)

Several cDNA clones, encoding prepropeptide of human collagen alpha 1(V) chain, have been isolated. The prepropeptide (1838 amino acids length) of the alpha 1(V) chain was composed of a putative signal peptide, a large NH2-terminal noncollagenous region, a main collagenous region, and a COOH-terminal noncollagenous region. The signal peptide contained many leucine residues. The NH2-terminal noncollagenous region was much larger than those of the other collagens and had a region homologous to the COOH-terminal domain of laminin A chain, but it did not contain a cysteine-rich region that was maintained in the region of the other collagens. This region also contained probable tyrosine sulfation sites, and short collagenous sequences that were interrupted by three noncollagenous segments. The main collagenous region of the alpha 1(V) chain consisted of 338 repeats of Gly-X-Y-triplet. This region had a high degree (82%) of homology with the amino acids of the collagen alpha 1(XI) chain. The COOH-terminal noncollagenous region resembled that of the alpha 1(XI) chain, too, and 8 residues of cysteine that were important for the formation of the triple helix structure of collagens were observed. These results suggest that the alpha 1(V) chain belongs to the fibrillar collagen relative to the alpha 1(XI) chain, but codon usage of the alpha 1(V) cDNA was clearly different from those of the other fibrillar collagens including the alpha 1(XI), while it was similar to type IV collagen. This result supposes a different evolution of the alpha 1(V) gene from those of the other fibrillar collagens.
Adaptive Dynamic Range Optimization for Cochlear Implants: A Preliminary Study (2002)

Continual adjustment of channel gains using ADRO provided improved sound quality and improved speech perception performance. Therefore, ADRO is a viable alternative to fixed channel gain and offers a means for cochlear implantees to gain more benefit from their devices.
Intrasubject comparison between technetium-99m-ECD and technetium-99m-HMPAO in healthy human subjects. (1992)

The pharmacokinetics and quality of planar and SPECT brain imaging of two 99mTc-labeled brain perfusion agents, d,l-hexamethyl propylene amine oxime (HMPAO) and ethyl cysteinate dimer (ECD), were compared in seven healthy, normal subjects. Both radiopharmaceuticals showed rapid brain uptake and had a net brain washout of less than 5% during the first 20 min after drug administration. However, during the same time period, 99mTc-ECD images of the head showed significantly less background facial uptake and retention when compared to 99mTc-HMPAO images. The brain-to-background contrast ratio of 99mTc-ECD (brain/neck) continued to improve over time and by 5 hr postadministration was 17 to 1 versus 2 to 1 for 99mTc-HMPAO. SPECT brain images of both agents show gray/white matter ratios that were unchanged over time and an intracerebral distribution consistent with blood flow. A blind read of these SPECT images also shows 99mTc-ECD to produce images that were "easier to interpret" with less extracerebral activity as compared to 99mTc-HMPAO. Repeat, whole-body planar spot imaging suggests that 99mTc-ECD was cleared more rapidly from the body than was 99mTc-HMPAO.
The physico‐chemical properties and protein denaturation potential of surfactant mixtures (1984)

Synopsis Protein denaturation was investigated to establish an in vitro evaluation method of surfactants in connection with their in vivo irritation potency to human skin. Eventually a new method with simplicity and high reproducibility was established by using quantitative analysis with gel-permeation chromatography (GPC). The protein denaturing potency of the commercially available surfactants was measured by using the developed method. Synergistic reduction in protein denaturation was observed in the mixed systems of anionic and amphoteric surfactants. The synergistic reduction was explained in terms of the physico-chemical properties of the mixed surfactants. A possible mechanism is the remarkable lowering of the total monomer concentration by the formation of hydrophobic complexes between the anionic and amphoteric surfactants.
