The Mobile Phone as a Multi OTP Device Using Trusted Computing (2010)

The rapid growth in the number of online services leads to an increasing number of different digital identities each user needs to manage. As a result, many people feel overloaded with credentials, which in turn negatively impacts their ability to manage them securely. Passwords are perhaps the most common type of credential used today. To avoid the tedious task of remembering difficult passwords, users often behave less securely by using low entropy and weak passwords. Weak passwords and bad password habits represent security threats to online services. Some solutions have been developed to eliminate the need for users to create and manage passwords. A typical solution is based on giving the user a hardware token that generates one-time-passwords, i.e. passwords for single session or transaction usage. Unfortunately, most of these solutions do not satisfy scalability and/or usability requirements, or they are simply insecure. In this paper, we propose a scalable OTP solution using mobile phones and based on trusted computing technology that combines enhanced usability with strong security.
Thermal Rebound of Nanometer Particles in a Diffusion Battery (1993)

The sticking probability of nanometer particles in diffusion batteries was calculated by means of the thermal rebound approach suggested by Wang and Kasper (1991). Particle penetration was then calculated from the classical theory of diffusion batteries, incorporating the effects of thermal rebound. A significant increase in penetration occurs for small particles, particles of hard materials, and particles with low adhesion energy. When the thermal rebound effects are not negligible, the measured penetration through a diffusion battery is a convoluted function of Peclet number, the screen parameter, and the thermal rebound parameter. The diffusion battery measurements alone can not resolve particle size distribution. The combination of a differential mobility analyzer and a diffusion battery can yield the information of mechanical and adhesion properties of nanometer particles.
Dynamics of Acute Inflammation (2004)

When the body is infected, it mounts an acute inflammatory response to rid itself of the pathogens and restore health. Uncontrolled acute inflammation due to infection is defined clinically as Sepsis and can culminate in organ failure and death. We consider a three dimensional ordinary differential equation model of inflammation consisting of a pathogen, and two inflammatory mediators. The model reproduces the healthy outcome and diverse negative outcomes, depending on initial conditions and parameters.when key parameters are changed and suggest various therapeutic strategies. We suggest that the clinical condition of sepsis can arise from several distinct physiological states, each of which requires a different treatment approach. We analyze the various bifurcations between the different outcomes
Establishment and characterization of a human A549 non small cell lung cancer cell line resistant to the novel vectorized cytotoxic drug F14512 (2008)

3237 F14512, a novel anticancer drug in pre-clinical development, combines a spermine chain with an epipodophyllotoxin warhead. Part of the benefit introduced by the spermine moiety of F14512 relies on a specific vectorization towards cancer cells mediated though the Polyamine Transport System (PTS). One of the most important challenges in chemotherapeutic treatment is to impede drug resistance. Along this line, we studied the profile of chemo-resistance induced by F14512, which was previously shown to display strong anti-proliferative activities both in vitro and in vivo. We performed the selection of a stable resistant A549 lung carcinoma cell line after 36 treatments with F14512 over 8 months. Interestingly, the pair-wise comparison of the selected A549 F0.5X sub-cell line and the parental cell line indicated that the long exposure to F14512 led to a moderate level of resistance (10 fold). The profile of drug response against a panel of clinically used reference compounds demonstrated that the F14512-resistant cell line is specifically but moderately cross-resistant to etoposide and doxorubicin. This result is consistent with the cross resistance of F14152 toward the mitoxantrone-resistant HL-60-MX2 cell line that arbors a mutated and reduced expression of the topoisomerase II target. In contrast to other epipodophyllotoxin-selected cell lines, none of the ABC transporters involved in clinical resistance phenotype (MDR1, MRP1, MRP2 and ABCG2) were found significantly over-expressed in the F14512-selected A549 cell line. Consistently, the A549 F0.5X sub-cell line displays a pattern of sensitivity against substrates of MDR1/MRP1 such as paclitaxel, navelbine, and displays a marked collateral sensitivity towards the antimetabolite gemcitabine. Proteomic analyses reveal few changes of protein expression between the resistant and parental cell lines, but we observed consistent down-regulation of a subset of proteins involved in the mitochondrial pathway, which is not classically associated with anticancer drug resistance. In conclusion, the spermine moiety of F14152 not only enhances markedly the anti-proliferative potency of the drug but also, and in contrast to conventional epipodophyllotoxins, it restricts the induction of ABC transporter-mediated drug resistance. F14512 appears as a novel drug candidate for the treatment of chemo-resistant tumors.
Identification of pre-mRNA polyadenylation sites in Saccharomyces cerevisiae. (1992)

In contrast to higher eukaryotes, little is known about the nature of the sequences which direct 3'-end formation of pre-mRNAs in the yeast Saccharomyces cerevisiae. The hexanucleotide AAUAAA, which is highly conserved and crucial in mammals, does not seem to have any functional importance for 3'-end formation in yeast cells. Instead, other elements have been proposed to serve as signal sequences. We performed a detailed investigation of the yeast ACT1, ADH1, CYC1, and YPT1 cDNAs, which showed that the polyadenylation sites used in vivo can be scattered over a region spanning up to 200 nucleotides. It therefore seems very unlikely that a single signal sequence is responsible for the selection of all these polyadenylation sites. Our study also showed that in the large majority of mRNAs, polyadenylation starts directly before or after an adenosine residue and that 3'-end formation of ADH1 transcripts occurs preferentially at the sequence PyAAA. Site-directed mutagenesis of these sites in the ADH1 gene suggested that this PyAAA sequence is essential for polyadenylation site selection both in vitro and in vivo. Furthermore, the 3'-terminal regions of the yeast genes investigated here are characterized by their capacity to act as signals for 3'-end formation in vivo in either orientation.
Near-Normal Incidence Dark-Field Microscopy: Applications to Nanoplasmonic Spectroscopy (2012)

The spectroscopic characterization of individual nanostructures is of fundamental importance to understanding a broad range of physical and chemical processes. One general and powerful technique that addresses this aim is dark-field microscopy, with which the scattered light from an individual structure can be analyzed with minimal background noise. We present the spectroscopic analysis of individual plasmonic nanostructures using dark-field illumination with incidence nearly normal to the substrate. We show that, compared to large incidence angle approaches, the near-normal incidence approach provides significantly higher signal-to-background ratios and reduced retardation field effects. To demonstrate the utility of this technique, we characterize an individual chemically synthesized gold nanoshell and a lithographically defined heptamer exhibiting a pronounced Fano-like resonance. We show that the line shape of the latter strongly depends on the incidence angle. Near-normal incidence dark-field microscopy can be used to characterize a broad range of molecules and nanostructures and can be adapted to most microscopy setups.

Layout and Present Status of the Closed-Cycle Helium Turbine Plant Oberhausen (1974)

The Oberhausen gas turbine plant now under construction is designed as a fossil-fired heating power station to produce a net electrical output at terminals of 50 MW. Helium as a working medium is employed for the first time in a closed-cycle industrial power plant system. A report is given on the layout of the circuit parameters, on the physical size of the turbomachines and heat exchangers as well as on the design of the gas-fired helium heater. Moreover, the arrangement of circuit components is discussed. The Oberhausen plant was projected under the aspect of a commercial thermal power station. Besides, the plant is of considerable importance concerning the German program for developing high-temperature reactors with helium turbines (HHT). Its significance is, on the one hand, based on the fact that the turbomachines and heat exchangers are constructed in many details to meet the requirements which occur in nuclear helium turbines of high output. Some of these components closely resemble dimensions and stresses as in a HHT-power plant. On the other hand the operational behavior of component parts will be tested under real conditions of a commercial power plant.
Molybdenum Disulfide Nanowires and Nanoribbons by Electrochemical/Chemical Synthesis (2005)

Molybdenum disulfide nanowires and nanoribbons have been synthesized by a two-step, electrochemical/chemical synthetic method. In the first step, MoO(x) wires (a mixture of MoO(2) and MoO(3)) were electrodeposited size-selectively by electrochemical step-edge decoration on a highly oriented pyrolytic graphite (HOPG) surface. Then, MoO(x) precursor wires were converted to MoS(2) by exposure to H(2)S either at 500-700 degrees C, producing "low-temperature" or LT MoS(2) nanowires that were predominantly 2H phase, or above 800 degrees C producing "high-temperature" or HT MoS(2) ribbons that were predominantly 3R phase. The majority of these MoS(2) wires and ribbons were more than 50 microm in length and were organized into parallel arrays containing hundreds of wires or ribbons. MoS(2) nanostructures were characterized by X-ray photoelectron spectroscopy, scanning and transmission electron microscopy, selected area electron diffraction, X-ray diffraction, UV-visible absorption spectrometry, and Raman spectroscopy. HT and LT MoS(2) nanowires were structurally distinct: LT MoS(2) wires were hemicylindrical in shape and nearly identical in diameter to the MoO(x) precursor wires from which they were derived. LT MoS(2) wires were polycrystalline, and the internal structure consisted of many interwoven, multilayer strands of MoS(2); HT MoS(2) ribbons were 50-800 nm in width and 3-100 nm thick, composed of planar crystallites of 3R-MoS(2). These layers grew in van der Waals contact with the HOPG surface so that the c-axis of the 3R-MoS(2) unit cell was oriented perpendicular to the plane of the graphite surface. Arrays of MoS(2) wires and ribbons could be cleanly separated from the HOPG surface and transferred to glass for electrical and optical characterization. Optical absorption measurements of HT MoS(2) nanoribbons reveal a direct gap near 1.95 eV and two exciton peaks, A1 and B1, characteristic of 3R-MoS(2). These exciton peaks shifted to higher energy by up to 80 meV as the wire thickness was decreased to 7 nm (eleven MoS(2) layers). The energy shifts were proportional to 1/ L( parallel)(2), and the effective masses were calculated. Current versus voltage curves for both LT and HT MoS(2) nanostructures were probed as a function of temperature from -33 degrees C to 47 degrees C. Conduction was ohmic and mainly governed by the grain boundaries residing along the wires. The thermal activation barrier was found to be related to the degree of order of the crystallites and can be tuned from 126 meV for LT nanowires to 26 meV for HT nanoribbons.

Design of 3D scanner for surface contour mapping by ultrasonic sensor (2015)

Surface mapping systems have attracted great attention due to their potential applications in many areas. In this paper, a simple 3D scanner based on ultrasonic sensor was designed for mapping a contour of object surface. The scanner using an SRF02 ultrasonic sensor, a microcontroller and radio frequency (RF) module to collect coordinates of object surface (point cloud), and sent data to computer. The point cloud collection process was performed by moving two ultrasonic sensors in y and x directions. Both sensors measure a distance from an object surface to a reference point of each sensor. The measurement results represent the point cloud of object surface and the data will be sent to computer via RF module. The point cloud then converted to 3D model using MATLAB. It was found that the object contours can be reconstructed very well by the developed 3D scanner system.
Novel Formations of Unsymmetrical 1,2,5-Benzotrithiepins from Olefins and Benzopentathiepin in the Presence of Lewis Acid. Benzopentathiepin as a Novel 1,5-Dipole Synthon (1989)

Abstract Some unsymmetrical 1,2,5-benzotrithiepins were synthesized in moderate to good yields by the novel reactions of various olefins with benzopentathiepin (BPT) in the presence of a Lewis acid, trifluoroborane etherate. In this reaction, BPT was found to serve as a 1,5-dipole synthon.

Molecules That Assemble by Sound:  An Application to the Instant Gelation of Stable Organic Fluids (2005)

The first molecule that assembles by ultrasound is described. An association-inert dinuclear Pd complex, anti-1a, which is stabilized by intramolecular pi-stacking interactions, gelatinizes a variety of organic solvents instantly upon brief presonication for a few seconds. This is the first quick, positive, and reversible method for the remote switching of stable sol-gel phases. Uniquely, the rate can be precisely controlled over the range between "no gelation" and "instant gelation" simply by tuning the sonication time.
The Impact of Total Quality Management (Tqm) on Competitive Advantage: A Conceptual Mixed Method Study in the Malaysia Luxury Hotel Industries (2018)

The widespread use of TQM has impacted the hotel industry worldwide and increasingly identified as the key issue in differentiating service products and building competitive advantage in tourism. Accordingly, hotel industries may face a wide variety of saturated and uncertain TQM practices available for their organization nowadays. As there is a lack of comprehensive knowledge regarding TQM issuesin hotel industry, there is an urgent need for a process which will assist hotel industries in Malaysia to evaluate these TQM practices and select the most appropriate one in order to provide the ideal management practices for the entire organization. As such, this study will propose a mixed method study where 10 hotel managers are initially interviewed, followed by a quantitative study of 122 additional managers. The aim of this study is to assist the hoteliers for identifying the proper TQM practices andthen evaluating the available practices that best fitted the hotel industry in Malaysia which could concomitantly help the Ministry of Tourism and Culture (MOTAC) to achieve its National Key Economic Area (NKEA) and contributing towards high nation incomein 2020.
Phase-sensitive plasmonic biosensor using a portable and large field-of-view interferometric microarray imager (2017)

Nanophotonics, and more specifically plasmonics, provides a rich toolbox for biomolecular sensing, since the engineered metasurfaces can enhance light-matter interactions to unprecedented levels. So far, biosensing associated with high-quality factor plasmonic resonances has almost exclusively relied on detection of spectral shifts and their associated intensity changes. However, the phase response of the plasmonic resonances have rarely been exploited, mainly because this requires a more sophisticated optical arrangement. Here we present a new phase-sensitive platform for high-throughput and label-free biosensing enhanced by plasmonics. It employs specifically designed Au nanohole arrays and a large field-of-view interferometric lens-free imaging reader operating in a collinear optical path configuration. This unique combination allows the detection of atomically thin (angstrom-level) topographical features over large areas, enabling simultaneous reading of thousands of microarray elements. As the plasmonic chips are fabricated using scalable techniques and the imaging reader is built with low-cost off-the-shelf consumer electronic and optical components, the proposed platform is ideal for point-of-care ultrasensitive biomarker detection from small sample volumes. Our research opens new horizons for on-site disease diagnostics and remote health monitoring.
Improving Model Robustness by Adaptively Correcting Perturbation Levels with Active Queries (2021)

In addition to high accuracy, robustness is becoming increasingly important for machine learning models in various applications. Recently, much research has been devoted to improving the model robustness by training with noise perturbations. Most existing studies assume a fixed perturbation level for all training examples, which however hardly holds in real tasks. In fact, excessive perturbations may destroy the discriminative content of an example, while deficient perturbations may fail to provide helpful information for improving the robustness. Motivated by this observation, we propose to adaptively adjust the perturbation levels for each example in the training process. Specifically, a novel active learning framework is proposed to allow the model interactively querying the correct perturbation level from human experts. By designing a cost-effective sampling strategy along with a new query type, the robustness can be significantly improved with a few queries. Both theoretical analysis and experimental studies validate the effectiveness of the proposed approach.
Intraoperative changes in transcranial motor evoked potentials and somatosensory evoked potentials predicting outcome in children with intramedullary spinal cord tumors (2014)

Intraoperative TcMEPs and SSEPs can predict the degree of postoperative motor deficit in pediatric patients undergoing IMSCT resection. This technique, combined with dorsal column mapping, is particularly useful in resecting lesions of the upper cervical cord, which are generally considered to be high risk in this population. Furthermore, the spinal cord appears to be less tolerant of repeated intraoperative SSEP decreases, with 3 successive insults most likely to yield postoperative sensory deficits. Changes in TcMEPs and SSEP waveforms can signal the need to guard against excessive manipulation thereby increasing the safety of tumor resection.
Purification, calcium binding properties, and ultrastructural localization of the 53,000- and 160,000 (sarcalumenin)-dalton glycoproteins of the sarcoplasmic reticulum. (1990)

The 53-kDa glycoprotein and sarcalumenin (160-kDa glycoprotein) were extracted from rabbit skeletal muscle sarcoplasmic reticulum with EGTA and purified by fractionation on DEAE-Sephadex A-25 and lentil lectin-Sepharose 4B. Sarcalumenin was shown to bind up to 400 nmol of Ca2+/mg of protein at pH 7.5, which is equivalent to binding of approximately 35 mol of Ca2+/mol of protein. The apparent dissociation constant was 300 microM in the presence of 20 mM KCl and 600 microM in 150 mM KCl. The 53-kDa glycoprotein did not bind any Ca2+ under the conditions examined. Immunoblot analysis of isolated sarcoplasmic reticulum subfractions demonstrated the presence of the two glycoproteins in both the longitudinal sarcoplasmic reticulum and the terminal cisternae. Their concentrations were higher, however, in the longitudinal sarcoplasmic reticulum vesicles. Comparative immunoelectron microscopic studies using monoclonal antibodies revealed a codistribution of the 53-kDa glycoprotein with the Ca2(+)-ATPase in all regions of the free sarcoplasmic reticulum. A similar distribution was found for sarcalumenin, although immunolabeling was much weaker. The colocalization of the 53-kDa glycoprotein and sarcalumenin with the Ca2(+)-ATPase and the Ca2+ binding properties of sarcalumenin suggest that the glycoproteins may be involved in the sequestration of Ca2+ in the nonjunctional regions of the sarcoplasmic reticulum.
Performance Optimization of Induction Motors During Voltage-Controlled Soft Starting (2004)

This paper deals with the performance optimization of medium/high-power induction motors during soft starting by eliminating the supply frequency torque pulsations, and by keeping the line current constant at the preset value. Starting torque pulsations are eliminated by triggering back-to-back-connected thyristors at proper points on the first supply voltage cycle. Line current during starting can be kept constant at any preset value by a simple strategy composed of successive cosinusoidal and constant function segments of the triggering angle. These strategies are implemented by the use of an 8-b microcontroller. Transient performance analyses of the system are carried out by means of a hybrid ABC/dq machine model which takes into account the three-phase, two-phase, and disconnected modes of operation in terms of actual stator variables. Experimental results obtained on a custom-design test bed are found to be in good agreement with the theoretical ones.
