"Healthy surveillance": Designing a concept for privacy-preserving mask\n recognition AI in the age of pandemics (2020)

The obligation to wear masks in times of pandemics reduces the risk of\nspreading viruses. In case of the COVID-19 pandemic in 2020, many governments\nrecommended or even obligated their citizens to wear masks as an effective\ncountermeasure. In order to continuously monitor the compliance of this policy\nmeasure in public spaces like restaurants or tram stations by public\nauthorities, one scalable and automatable option depicts the application of\nsurveillance systems, i.e., CCTV. However, large-scale monitoring of mask\nrecognition does not only require a well-performing Artificial Intelligence,\nbut also ensure that no privacy issues are introduced, as surveillance is a\ndeterrent for citizens and regulations like General Data Protection Regulation\n(GDPR) demand strict regulations of such personal data. In this work, we show\nhow a privacy-preserving mask recognition artifact could look like, demonstrate\ndifferent options for implementation and evaluate performances. Our conceptual\ndeep-learning based Artificial Intelligence is able to achieve detection\nperformances between 95% and 99% in a privacy-friendly setting. On that basis,\nwe elaborate on the trade-off between the level of privacy preservation and\nArtificial Intelligence performance, i.e. the "price of privacy".\n
Effect of the Plate Thermal Resistance on the Performance of a Primary Surface Heat Exchanger (2002)

Two-dimensional conjugate conduction/convection numerical simulations were carried out for flow and thermal fields in the minimal unit model of a counter flow type corrugated plate heat exchanger to study the effects of plate thermal resistance on its thermal characteristics. Computations were carried out for two plate geometries having different plate thickness in the Reynolds number range of 100<Re<400. It was found that the case of thicker corrugated plate can have the better heat transfer performance compared with the thinner one, taking a higher value of the temperature effectiveness for unit length at a fixed pumping power. This is ascribed to the combined effects of change in plate shape due to the different plate thickness and the decrease of thermal resistance inside the solid part in tangential direction of the plate surface.
Simulation modeling with artificial reality technology (SMART): an integration of virtual reality and simulation modeling (1998)

Simulation Modeling with Artificial Reality Technology (SMART) is a simulation modeling tool that provides a virtual reality interface for building graphical simulation models. The simulation models, comprised of nodes and arcs, are constructed in three dimensions. As the user builds a model, he may immerse himself in it using virtual reality hardware and software tools and take advantage of the three dimensional environment provided by SMART. Models built using SMART can be exported to AweSim, and simulated as SLAM models (Pristker et al., 1996). The virtual reality hardware includes an electronic glove and head-mounted display. The specific hardware is the 5DT Glove (Fifth Dimension Technologies, 1996) and VIO I-Glasses (Virtual I-O, 1995), respectively. By wearing the 5DT Glove, the user can navigate through virtual space and manipulate a three dimensional simulation model. The VIO I-Glasses allows the user to experience immersion in the virtual modeling world. The head-mounted device constantly responds to the motions of the user's head to reflect changes in his view of the virtual world. With SMART, simulation practitioners are no longer restricted to building simulation models on a flat two dimensional space. Rather, they can now build three dimensional simulation models with high non-planar complexity through the virtual reality interface provided by SMART.
Long-term treatment with cinacalcet and conventional therapy reduces parathyroid hyperplasia in severe secondary hyperparathyroidism (2008)

Cinacalcet, in combination with conventional treatments, led to an improvement in biochemical and clinical parameters of sHPT and reduced glandular volume in patients with severe sHPT. Volume reduction was more evident in smaller glands. Longer term, larger, randomized clinical trials are needed to confirm these preliminary findings and to further define a more systematic approach in the treatment of sHPT.

Holes in lattices in liquids (2020)

In their feature article in the February 2019 issue of Physics Today (page 38), Robert Evans, Daan Frenkel, and Marjolein Dijkstra quote from “About liquids,” an essay in which Victor Weisskopf discusses the mysterious nature of liquids.11. V. F. Weisskopf, Trans. N. Y. Acad. Sci. 38, 202 (1977). https://doi.org/10.1111/j.2164-0947.1977.tb02959.xAround 1960, when I was a graduate student at the University of Washington, the thesis project of one of my fellows was to calculate the entropy of a hole in a crystal lattice. The seemingly quixotic nature of the assignment—“A hole is a nothing. How can it have an entropy?”—led to much merry banter in our group. Today, the idea of holes in lattices is well established.Evaporation (or sublimation) occurs when molecules on the surface of a condensed phase acquire enough energy to break free, enter the gas phase, and thus achieve unconstrained mobility. Similarly, for crystalline solids, there is a characteristic temperature—the melting temperature—at which the holes become mobile and move freely throughout the lattice. Noncrystalline solids such as rubber and plastics have a range of hole and dislocation types that reach mobility at various temperatures; they soften gradually rather than exhibiting a sharp melting point.I find that the molecule/hole analogy provides a satisfying way to visualize the phenomenon of melting and the nature of liquids.ReferenceSection:ChooseTop of pageReference <<1.

Neural network for estimation of harmonic components in a power system (1992)

The paper presents a novel approach to the estimation of harmonics in the power system. The proposed method uses the optimisation neural network theory and its implementation in an analogue form. As is proven in the paper, this formulation, and its practical implementation, leads to the correct solution of the problem in real time. The solution presented is inexpensive and suitable for use with the solid state compensating systems to improve the quality of delivered energy.

TMUCl Cl, the Efficient Reagent for the Solid-Phase Synthesis of Anilides (2005)

The solid-phase synthesis of anilides was performed by use of N-[chloro(dimeth­ylamino)methylene]-N-methylmethanaminium chloride (TMUCl Cl), which was identified to be an efficient reagent for the activation of solid-supported carboxylic acid. Thus, Ac-Glu(OH)-Rink-PS-resin 1 was treated with both 10 equivalents of TMUCl Cl and N,N-diisopropylethylamine (DIPEA) for activation of the carboxylic acid group followed by the reaction with 5 equivalents of 4-nitroaniline for 2 h to give 4-nitroanilide. The purity of the anilide was determined by RP-HPLC analysis after cleavage with TFA-H2O to be 78%.
The relaxosome protein MobC promotes conjugal plasmid mobilization by extending DNA strand separation to the nick site at the origin of transfer (1997)

The frequency of conjugal mobilization of plasmid R1162 is decreased approximately 50-fold if donor cells lack MobC, one of the plasmid-encoded proteins making up the relaxosome at the origin of transfer (oriT). The absence of MobC has several different effects on oriT DNA. Site- and strand-specific nicking by MobA protein is severely reduced, accounting for the lower frequency of mobilization. The localized DNA strand separation required for this nicking is less affected, but becomes more sensitive to the level of active DNA gyrase in the cell. In addition, strand separation is not efficiently extended through the region containing the nick site. These effects suggest a model in which MobC acts as a molecular wedge for the relaxosome-induced melting of oriT DNA. The effect of MobC on strand separation may be partially complemented by the helical distortion induced by supercoiling. However, MobC extends the melted region through the nick site, thus providing the single-stranded substrate required for cleavage by MobA.

Cell-Based Microarrays: Overview (2010)

Cell-based microarrays were first described by Ziauddin and Sabatini in 2001 as a novel method for performing high-throughput screens of gene function. They reported a technique whereby expression vectors containing the open reading frame (ORF) of human genes were printed onto glass microscope slides to form a microarray. Transfection reagents were added pre- or post-spotting and cells grown over the surface of the array. They demonstrated that cells growing in the immediate vicinity of the expression vectors underwent 'reverse transfection' and that subsequent alterations in cell function could then be detected by secondary assays performed on the array. Subsequent publications have adapted the technique to a variety of applications and have also shown that the approach works when arrays are fabricated using siRNAs and compounds. The potential of this method for performing analyses of gene function and identification of novel therapeutic agents has now been clearly demonstrated. Current efforts are focused on improving and harnessing this technology for high-throughput screening applications.
Evaluation of Bladder Washing Cytology for Bladder Cancer Surveillance (1978)

The history of ultrasound in polymer chemistry goes back a long way. Initially, its uses were limited to being an alternative method of initiating radical polymerizations through the decomposition of solvents to form radicals or through the breakage of polymers leading to macroradicals. Recently, the raw power of ultrasound has been focused through the use of weak linkages in polymer chains, which enables the production of well-defined macroradicals and coordinatively unsaturated metal complexes.
Mechanisms for Metal-Nonmental Transitions in Transition-Metal Oxides and Sulfides (1968)

Transition-metal oxides and sulfides can be insulators, semiconductors, or metals, or undergo metal-nonmetal transitions. The experimental situation in these materials is briefly reviewed. Pure Bloch-Wilson theory predicts that many of the insulators should be metallic, so this class cannot be explained in terms of pure band theory. However, it now appears likely that band theory can be adapted to describe most of the materials that exhibit metal-nonmetal transitions.
Script Cards: A Visual Programming Language for Games Authoring by Young People (2006)

This paper describes Script Cards, a visual programming language which enables young people to script story events in a 3D role-playing game (Neverwinter Nights). Script Cards is designed to eliminate the need to learn a complex scripting language when creating interactive stories. An initial evaluation of Script Cards suggests that young people found it easy to use.
[Studies on pyridonecarboxylic acids as antibacterial agents. XIV. Synthesis and structure-activity relationships of 7,8-disubstituted-1-cyclopropyl-6-methyl-1,4-dihydro-4-oxo-3-quinoline carboxylic acids]. (1998)

Eighteen pyridonecarboxylic acids, characterized by a methyl group at the C6-position instead of the usual fluorine atom, cyclopropyl at the N1-position, substituted amino groups at the C7-position, and some substituted groups (hydrogen, chlorine, nitro and amino) at the C8-position, were synthesized. The in vitro antibacterial activity of these compounds were tested, and the structure-activity relationships were also discussed. The results of the study showed that the activity of compounds 22 and 24 were less potent than that of ciprofloxacin against S. aureus, S. epidermidis, E. coli and P. aeruginosa, while they were 2-100 times more potent than ciprofloxacin against K. pneumoniae, S. marcescens, A. calcoacetous, E. aerogenes, S. typhi and S. typhimurium.
Black Tea Polyphenols Reverse Epithelial-to-Mesenchymal Transition and Suppress Cancer Invasion and Proteases in Human Oral Cancer Cells (2012)

Epithelial-to-mesenchymal transition (EMT) in cancer cells is considered to be a prerequisite for acquiring invasive/migratory phenotype and subsequent metastasis. This study provides molecular evidence associated with the antimetastatic effect of black tea polyphenol extracts (BTE), which contain polyphenols including gallic acid, gallocatechin, catechin, epigallocatechin-3-gallate, epicatechin-3-gallate, and theaflavin 3,3'-digallate, in an an oral squamous cell culture system by showing a nearly complete inhibition on the invasion (p < 0.001) of SCC-4 cells via reduced activities of MMP-2 (p < 0.001) and u-PA (p < 0.001). Immunoblot was performed to find that BTE could induce up-regulation of epithelial markers such as E-cadherin and inhibit mesenchymal markers such as snail-1 and vimentin. BTE inhibited p-FAK and p-paxillin, indicating the anti-EMT effect of BTE in oral squamous cell carcinoma. BTE was evidenced by its inhibition of the tumor growth of SCC-4 cells via cancer cell xenografted nude mice mode. These results suggested that BTE could reduce invasion by reversing EMT in human oral cancer cells.
Cloning & expression of chikungunya virus genes coding structural proteins in Escherichia coli. (1990)

DNA complementary to the single stranded RNA genome of Chikungunya (CHIK) virus with poly A tract was cloned into the plasmid pGEM-3Zf(-) and 5Zf(+) by blunt end ligation strategy. Clones containing the cDNA inserts were selected by X-gal, IPTG system. They were tested for the expression of structural protein(s) of CHIK virus by in situ enzyme immunoassay and Western blot. The former assay system showed the presence of expressed viral proteins. Analysis of Western blot shows that three structural proteins, E1, E2 and capsid (C) are expressed in Esch. coli. The molecular weights of envelope proteins E1 and E2 were 44-46 Kd and 42-44 Kd respectively, which are lesser than the actual molecular weights of virional proteins (50-52 Kd). This may be due to the absence of glycosylation of these proteins in Esch. coli. In clone no. 382, a high molecular weight protein (56-58 Kd) was observed, which was probably the unglycosylated form of P62 polyprotein coded by the virus during its multiplication. A small protein of MW 6-8 Kd was also expressed in clone nos. 382 and 504, and this appeared to be the unglycosylated form of E3 protein of CHIK virus.
Development of a gated scintillation fiber neutron detector for areal density measurements of inertial confinement fusion capsules (2003)

A detector for fuel areal density measurements in inertial confinement fusion capsules has been designed. Observation of neutrons scattered in an imploded deuterium capsule (0.27–0.6 MeV) is a promising method for areal density measurements in the National Ignition Facility DD surrogate capsules. In order to detect scattered neutrons, we need to (1) suppress interference due to the strong direct neutron burst and (2) suppress the background produced by neutrons scattering on nontarget material (mainly from the target chamber). In our detector system, we suppress direct neutrons by gating the detector. We suppress the nontarget background neutrons by placing the detector outside the target chamber and limiting the view of the detector with collimators. In addition, we are developing a lithium-glass scintillation-fiber detector (LG-SCIFI) to detect the scattered neutrons. The LG-SCIFI will work as a multichannel scintillator array. The scintillation signal will be amplified by a microchannel plate image intensifier, which is gated to accept signals only in a specific time-of-flight window for the scattered neutrons. The gated scintillation image will be recorded by a charge-coupled device. Since the detector is segmented, neutron detection events will be clearly identified as bright spots in the gated image.
Design of a sensorless commutation IC for BLDC motors (2003)

This paper presents the design and realization of a sensorless commutation integrated circuit (IC) for brushless DC motors (BLDCMs) by using mixed-mode IC design methodology. The developed IC can generate accurate commutation signals for BLDCMs by using a modified back-EMF sensing scheme instead of using Hall-effect sensors. This IC can be also easily interfaced with a microcontroller or a digital signal processor (DSP) to complete the closed-loop control of a BLDCM. The developed sensorless commutation IC consists of an analog back-EMF processing circuit and a programmable digital commutation control circuit. Since the commutation control is very critical for BLDCM control, the proposed sensorless commutation IC provides a phase compensation circuit to compensate phase error due to low-pass filtering, noise, and nonideal effects of back-EMFs. By using mixed-mode IC design methodology, this IC solution requires less analog compensation circuits compared to other commercially available motor control ICs. Therefore, high maintainability and flexibility can be both achieved. The proposed sensorless commutation IC is integrated in a standard 0.35-/spl mu/m single-poly four-metal CMOS process, and the realization technique of this mixed-mode IC has been given. The proposed control scheme and developed realization techniques provide illustrative engineering procedures for the system-on-a-chip solution for advanced digital motor control. Simulation and experimental results have been carried out in verification of the proposed control scheme.
A New Remote-controlled Animal Robot Training System (2007)

This paper presents a new scatheless platform for training remote-controlled animal robot, which can be used to analyze the relations between electrical stimulation and animal behavior. It will not only provide a convenient platform and method to research the controllability of animal behavior and the possibility of training animal robots, but also open new possibilities for biomedical, artificial intelligence and cognitive science researches. This system consists of two parts: 1) multichannel remote-controlled stimulator backed by animal; 2) computer vision based animal motion-analysis system. The training results showed that the platform works accurately even under interference conditions.
From 2D TO 3D Through Modelling Based On A Single Image (2008)

Abstract Three‐dimensional modelling from single images remains an interesting topic of investigation in the research community, even though range sensors are becoming a common alternative for the generation of 3D information. The interest in single‐image‐based modelling is motivated by a wide spectrum of applications such as cultural heritage, civil engineering, urban planning and even criminology. In this paper a complete new production flowline is presented for modelling based on a single image. The modelling process consists of a series of familiar steps in photogrammetry and computer vision: feature extraction, vanishing point computation, camera self‐calibration, 3D reconstruction and dimensional analysis. In particular, the methodology developed for single‐image‐based modelling takes a scientific approach combining several proven techniques with robust estimators. Finally, in order to demonstrate its capabilities, the reported examples include several real situations applied in different contexts.
Fetal Leydig Cells: Progenitor Cell Maintenance and Differentiation (2010)

In most eutherian mammals, sexually dimorphic masculinization is established by androgen-producing fetal Leydig cells in the embryonic testis. Fetal Leydig cells, which lack expression of the testis-determining gene SRY, arise after the appearance of SRY-expressing Sertoli cells. Therefore, the appearance and differentiation of fetal Leydig cells are probably regulated by factors derived from Sertoli cells. Results from mouse genetic models have revealed that maintenance and differentiation of fetal Leydig cell population depends upon a balance between differentiation-promoting and differentiation-suppressing mechanisms. Although paracrine signaling via Sertoli cell-derived Hedgehog ligands is necessary and sufficient for fetal Leydig cell formation, cell-cell interaction via Notch signaling and intracellular transcription factors such as POD1 are implicated as suppressors of fetal Leydig cell differentiation. This review provides a model that summarizes the recent findings in fetal Leydig cell development.

Assignment of the Photoyellowing-Related 1675 cm<sup>−1</sup>Raman/IR Band to P-Quinones and Its Implications to the Mechanism of Color Reversion in Mechanical Pulps (1998)

Abstract Using FT (Fourier-transform) Raman and FT infrared (IR) spectroscopies, a new band was detected at 1675 cm−1; this was most likely to have come from the yellow chromophores in photoexposed thermomechanical pulps (TMPs). On the basis of spectroscopic studies that involved both o- and p-quinone models and Fremy's salt-oxidized TMP, the 1675 cm−1 band is assigned to the p-quinone functional group. Moreover, in the presence of known photoyellowing inhibitors, the photoyellowing behavior of methyl hydroquinone was similar to that of TMPs. Another important finding was that the molecular oxygen sensitivity of the laser-induced fluorescence (excited at 514.5 nm) of p-quinone and hydroquinone models was similar to what had been previously observed for yellowed and unyellowed TMPs. Taken together, these results provide strong support for a previously suggested yellowing hypothesis in which a hydroquinone/p-quinone couple was seen as an important leucochromophore/chromophore system in mechanical pulps.
