A Prototype RFID Humidity Sensor for Built Environment Monitoring (2008)

This paper presents a prototype RFID humidity sensor capable of passive wireless sensing through far-field backscatter coupling. A commercial UHF RFID tag is employed as a sensing platform to receive the power and to reflect the sensed data back to the RFID reader. A humidity sensitive polyimide film is incorporated onto the top surface of the RFID tag for humidity sensing. The prototype sensor demonstrated that power required to activate the sensor tag is a linear function of relative humidity and the maximum sensing distance between the reader antenna and the RFID humidity sensor tag reaches to about 1.5 m. Due to its unique features of low cost, battery-less wireless operation, maintenances-free, and disposable, the RFID humidity sensor can be integrated into wallpaper for humidity monitoring in a built environment.
Security of biometric authentication systems (2010)

This overview paper outlines our views of actual security of biometric authentication and encryption systems. The attractiveness of some novel approaches like cryptographic key generation from biometric data is in some respect understandable, yet so far has lead to various shortcuts and compromises on security. Our paper starts with an introductory section that is followed by a section about variability of biometric characteristics, with a particular attention paid to biometrics used in large systems. The following sections then discuss the potential for biometric authentication systems, and for the use of biometrics in support of cryptographic applications as they are typically used in computer systems.
HAP1 and ROX1 Form a Regulatory Pathway in the Repression of <i>HEM13</i> Transcription in <i>Saccharomyces cerevisiae</i> (1992)

HEM13 of Saccharomyces cerevisiae encodes coproporphyrinogen oxidase, an enzyme in the heme biosynthetic pathway. Expression of HEM13 is repressed by oxygen and heme. This study investigated the regulatory pathway responsible for the regulation of HEM13 expression. The transcriptional activator HAP1 is demonstrated to be required for the full-level expression of HEM13 in the absence of heme. It is also shown that the repression of HEM13 transcription caused by heme involves the HAP1 and ROX1 gene products; a mutation in either gene results in derepression of HEM13 expression. The heme-dependent expression of ROX1 was found to require functional HAP1, leading one to propose that repression of HEM13 results from a pathway involving HAP1-mediated regulation of ROX1 transcription in response to heme levels followed by ROX1-mediated repression of HEM13 transcription. In support of this model, expression of ROX1 under control of the GAL promoter was found to result in repression of HEM13 transcription in a hap1 mutant strain. The ability of ROX1 encoded by the galactose-inducible ROX1 construct to function in the absence of HAP1 indicates that the only role of HAP1 in repression of HEM13 is to activate ROX1 transcription.

Synthesis of a Chiral Precursor for No-Carrier-Added (NCA) PET Tracer 6-[18F]Fluoro-L-dopa Based on Regio- and Enantioselective Alkylation of 2,4-Bis(chloromethyl)-5-iodoanisole (2000)

Abstract (2S,5S)-5-(3-Formyl-6-iodo-4-methoxybenzyl)-1-t-butoxycarbonyl-2-t-butyl-3-methyl-4-imidazolidinone (11), a chiral intermediate towards NCA PET tracer 6-[18F]fluoro-L-dopa (1), was synthesized from 3-iodoanisole in four steps. 3-Iodoanisole was first bischloromethylated to 2,4-bis(chloromethyl)-5-iodoanisole (14). Regio- and enantio-selective alkylation of 14 with (S)-1-(t-butoxycarbonyl)-2-t-butyl-3-methyl-4-imidazolidinone (12) afforded 33, which was then hydrolyzed and oxidized to the desired intermediate 11.
Similar isoelectric profiles of FSH from gonadotroph cell adenomas and non-adenomatous pituitaries (1986)

Heterogeneity of intact FSH in human pituitary tissue was evaluated by the column isoelectric focusing technique, chromatofocusing. FSH was examined from three autopsy pituitaries, one piece of apparently normal pituitary obtained at surgery, three purified FSH preparation, and four gonadotroph cell adenomas. FSH from all of these sources was found to exist in multiple isoelectric forms. FSH from the gonadotroph cell adenomas exhibited chromatofocusing profiles that were similar, both in the range of pI's and the relative proportions of the FSH isohormones, to those of the non-adenomatous pituitaries. We conclude that gonadotroph cell adenomas produce a population of FSH that is qualitatively normal although quantitatively excessive.

The Scandinavian Odor-Identification Test: Development, Reliability, Validity and Normative Data (1998)

The Scandinavian Odor-Identification Test (SOIT) was developed to address the need for a culturally valid odor-identification test for clinical use on the Scandinavian population that (i) has good ability to generalize performance to olfactory status, (ii) assesses olfactory and trigeminal function separately, (iii) requires only limited cognitive demands, (iv) has normative data and good sensitivity and specificity, and (v) is fast, easy to administer and inexpensive. Sixteen odorous test stimuli were selected that were relatively identifiable, familiar, strong in intensity and pleasant according to healthy participants. Four response alternatives were then selected for each test stimulus based on a confusion matrix of identification rates obtained from healthy participants, in a manner that controlled for task difficulty. Results on the SOIT from healthy persons and hyposmic patients showed satisfactory test-retest reliability, split-half reliability and validity. Cut-off scores for olfactory diagnosis (normosmia, hyposmia, anosmia) based on normative data obtained from 171 healthy persons showed a satisfactory sensitivity and specificity of the SOIT. Assessment of 22 anosmic patients with the SOIT revealed that three of the test stimuli were significant trigeminal stimulants.

LTAG dependency parsing with bidirectional incremental construction (2008)

In this paper, we first introduce a new architecture for parsing, bidirectional incremental parsing. We propose a novel algorithm for incremental construction, which can be applied to many structure learning problems in NLP. We apply this algorithm to LTAG dependency parsing, and achieve significant improvement on accuracy over the previous best result on the same data set.
Polarization-insensitive meta-lens doublet with large view field in the ultraviolet region (2019)

Dielectric metasurfaces is a plane optical device to achieve the desired function by modulating amplitude and phase, polarization for the incident light, and its transmission efficiency is higher than other metasurfaces, these advantages lead to dielectric metasurfaces will be used widely in the future. Nevertheless, the majority of metasurfaces are planar singlelayered structure, which limit seriously the view field and effect of monochromatic imaging. Here, we demonstrate a composed dielectric meta-lens doublet by the electromagnetic simulation can achieve perfectly diffraction-limited monochromatic focus for the polarization-insensitive incident lights at a wavelength of 375 nm, which has the view field of 60°, the numerical aperture of 0.5, and a focal length of 380μm. Due to the dielectric meta-lens doublet has the scaling of subwavelength at ultraviolet light, and the devices have high distinguishability, it can be used widely in nanolithography, imaging with large view field, and other optical domains.
Grid Computing: Making the Global Infrastructure a Reality (2003)

Grid computing is applying the resources of many computers in a network to a single problem at the same time Grid computing appears to be a promising trend for three reasons: (1) Its ability to make more cost-effective use of a given amount of computer resources, (2) As a way to solve problems that can't be approached without an enormous amount of computing power (3) Because it suggests that the resources of many computers can be cooperatively and perhaps synergistically harnessed and managed as a collaboration toward a common objective. A number of corporations, professional groups, university consortiums, and other groups have developed or are developing frameworks and software for managing grid computing projects. The European Community (EU) is sponsoring a project for a grid for high-energy physics, earth observation, and biology applications. In the United States, the National Technology Grid is prototyping a computational grid for infrastructure and an access grid for people. Sun Microsystems offers Grid Engine software. Described as a distributed resource management tool, Grid Engine allows engineers at companies like Sony and Synopsys to pool the computer cycles on up to 80 workstations at a time. "the Grid" is a very hot topic generating broad interest from research and industry (e.g. IBM, Platform, Avaki, Entropia, Sun, HP) Grid architecture enables very popular e-Science projects like the Genome project which demand global interaction and networking In recent surveys over 50% of Chief Information Officers are expected to use Grid technology this year Grid Computing: Features contributions from the major players in the field Covers all aspects of grid technology from motivation to applications Provides an extensive state-of-the-art guide in grid computing This is essential reading for researchers in Computing and Engineering, physicists, statisticians, engineers and mathematicians and IT policy makers

New design technique for two-step flash A/D convertors (1990)

A new design method for an N-bit, two-step, flash A/D convertor is presented which requires only 2(N-1) comparators. The most significant bit is first detected which then controls the switch settings for the second step of conversion. The new technique also simplifies the encoder design.
<i>LC</i> PLL With 1.2-Octave Locking Range Based on Mutual-Inductance Switching in 45-nm SOI CMOS (2009)

A wideband <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LC</i> PLL in 45-nm SOI CMOS technology is presented that has a center frequency of 12.4 GHz and 1.2 octave locking range. The wideband operation is achieved by switching mutual inductances within the inductor coil of the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LC</i> oscillator. To minimize resistive switching losses, the inductor coil consists of a non-switchable primary coil and two isolated secondary coils with series switches. When the switches are closed, the overall inductance reduces because of the switched mutual inductances. Three inductor bands, each consisting of 16 switched capacitor sub-bands, span a frequency range from 7.3 to 17.5 GHz. The in-band phase noise measured after a 1/4 divider is better than -107 dBc/Hz at 1 MHz offset frequency in the entire locking range. The PLL is fully differential and its core has a power consumption of 25 mW at the highest oscillation frequency.
Identification of terrain mechanical parameters for a six-wheeled lunar rover (2008)

In future planetary exploration missions, the lunar rovers will be working in the incompletely known and uncultured environment, wheel-terrain interaction plays a critical role in rough-terrain mobility. In this paper an on-line estimation method that identifies wheel-ground contact angle and wheel slip from trajectory data using an extended Kalman filter is firstly presented. Secondly, the use of a suitable soil model can then allow key soil parameters to be estimated as the rover passes over the soil. Knowledge of the soil parameters may in turn be used to allow reference trajectories and control algorithms to be adjusted to suit the soil condition. Simulation and experiment results show that the terrain and control parameters algorithms can accurately and efficiently be identified for loose sand.

The human immunoglobulin C<sub>μ</sub>–C<sub>δ</sub>locus: complete nucleotide sequence and structural analysis (1989)

The entire nucleotide sequence (approximately 20 kbp) spanning the human immunoglobulin IgM (mu) and IgD (delta) heavy chain constant region genes has been determined from DNA of mu-delta producing chronic lymphocytic leukemic B cells. As in the murine IgM + IgD double-producing B cells, no rearrangement has occurred in the C mu-C delta region in the leukemic cells. The C mu locus is highly conserved between mouse and human with the exception of the nucleotide sequence between the C mu 4 and mu M1 exons, which has diverged dramatically. The intergenic sequence between human C mu and C delta is three times larger than the analogous region in the mouse and contains notable features absent from the mouse, including a 443 bp segment that is 96% identical to a 442 bp sequence that occurs just 3' to the heavy chain enhancer, a 366 bp sequence that is directly repeated with 76% homology, and 12 tandem copies of a 35 bp sequence. The human C delta gene contains two additional exons relative to mouse C delta, but shares with the mouse the unique distal location of both secreted and membrane coding segments. Several polymorphisms in the human population have been identified in the intergenic region and in C delta but not in C mu.
Epstein-Barr Virus Entry Utilizing HLA-DP or HLA-DQ as a Coreceptor (2000)

Epstein-Barr virus (EBV) glycoprotein gp350/gp220 association with cellular CD21 facilitates virion attachment to B lymphocytes. Membrane fusion requires the additional interaction between virion gp42 and cellular HLA-DR. This binding is thought to catalyze membrane fusion through a further association with the gp85-gp25 (gH-gL) complex. Cell lines expressing CD21 but lacking expression of HLA class II molecules are resistant to infection by a recombinant EBV expressing enhanced green fluorescent protein. Surface expression of HLA-DR, HLA-DP, or HLA-DQ confers susceptibility to EBV infection on resistant cells that express CD21. Therefore, HLA-DP or HLA-DQ can substitute for HLA-DR and serve as a coreceptor in EBV entry.
Pumping schemes for multi-kW thin disk lasers (2000)

Various pumping schemes for operating thin disk lasers are reported. Starting from quasi-end-pumping of one disk we will discuss how multiple absorption passes in the laser crystal can be realized by using iterative relay imaging. This concept can be extended for pumping several disks simultaneously in one compact setup. For multi-kW operation of the thin disk laser edge-pumping of the laser crystal is proposed for even better performance of the thin disk laser compared to quasi-end-pumped schemes.
A 0.35 μm trench gate MOSFET with an ultra low on state resistance and a high destruction immunity during the inductive switching (2002)

This paper describes performance of 20 V class N-channel MOSFET using 0.35 /spl mu/m trench gate structure. It has two characteristics mainly. The first is an ultra low on state resistance by shrinking the trench gate width and increasing cell densities. The other is a high destruction immunity during the inductive switching by optimizing a trench depth. The measured specific on-resistance (Ron,sp) is 25% reduction comparing conventional one. Furthermore, this device can provide high avalanche current density during the inductive switching of JD=30 A/mm/sup 2/.
A catalytic role for threonine‐12 of <i>E. coli</i> asparaginase II as established by site‐directed mutagenesis (1991)

A threonine-12 to alanine mutant of E. coli asparaginase II (EC 3.5.1.1) has less than 0.01% of the activity of wild-type enzyme. Both tertiary and quaternary structure of the enzyme are essentially unaffected by the mutation; thus the activity loss seems to be the result of a direct impairment of catalytic function. As aspartate is still bound by the mutant enzyme, Thr-12 appears not be involved in substrate binding.

Noise estimation in strobed comparators (1997)

A simple estimation of the input referred noise and its relationship to speed and power dissipation in a strobed comparator is presented. The results are validated using a closed-loop noise measurement technique based on the output decision probability variation for inputs close to the transition point.
Enhancements to prestack frequency-wavenumber (f-k) migration (1991)

Abstract Prestack frequency-wavenumber (f-k) migration is a particularly efficient method of doing both full prestack time migration and migration velocity analysis. Conventional implementations of the method, however, can encounter several drawbacks: (1) poor resolution and spatial aliasing noise caused by insufficient sampling in the offset dimension, (2) poor definition of steep events caused by insufficient sampling in the velocity dimension, and (3) inadequate handling of ray bending for steep events. All three of these problems can be mitigated with modifications to the prestack f-k algorithm. The application of linear moveout (LMO) in the offset dimension prior to migration reduces event moveout and hence increases the bandwidth of non-spatially aliased signals. To reduce problems of interpolation for steep events, the number of constant-velocity migrations can be economically increased by performing residual poststack migrations. Finally, migration with a dip-dependent imaging velocity addresses the issue of ray bending and thereby improves the positioning of steep events. None of these enhancements substantially increases the computational effort of f-k migration.Prestack f-k migration possesses a limitation for which no solution is readily available. Where lateral velocity variation is modest, steep events (such as fault-plane reflections in sediments) may not be imaged as well as by other migration approaches. This shortcoming results from the restriction that, in the prestack f-k approach, a single velocity field must serve to perform two different functions: imaging and stacking. Nevertheless, in areas of strong velocity variation and gentle to moderate dip, the detailed velocity control afforded by the prestack f-k method is an excellent source of geologic information.
