Synthesis and characterization of styrene-N-butyl maleimide copolymers using iniferters containing thiyl end groups (1998)

The radical homopolymerization of styrene or copolymerization of styrene (S) with N-butyl maleimide (I) initiated by tetraethylthiuram disulfide was used to prepare macroinitiators having thiyl end groups. The S–I copolymers from the feeds containing 30–70 mol % I showed approximately alternating composition. The rate of copolymerization and molecular weights decreased with increasing maleimide derivative concentration in the feed; homopolymerization of I alone did not proceed. The macroinitiators served for synthesis of further S–I copolymers. Using polystyrene macroinitiator and the S–I copolymer with thiyl end groups in the polymerization of S–I mixture and styrene, respectively, the copolymers containing blocks of both polystyrene and alternating S–I copolymer were obtained. The copolymerization of S–I mixture initiated with the S–I copolymer bearing thiyl end groups led to the extension of macroinitiator chains by the blocks of alternating copolymer. The presence of the blocks in the polymer products was corroborated using elemental analysis, size exclusion chromatography, and differential scanning calorimetry. © 1998 John Wiley & Sons, Inc.

Mutual Chip Authentication (2013)

We present a Anonymous Mutual Authentication (AMA) protocol for authentication and key agreement between cryptographic devices. It is an alternative for Terminal Authentication (TA) plus Chip Authentication (ChA) developed for electronic travel documents. Unlike conventional TA, executing AMA does not provide any digital record that could be used as a proof against third parties that an interaction really took place. AMA is symmetric: the code executed by both participants is the same (apart from the sequence of operations). It eases implementation on resource limited devices such as smart cards. AMA does not require prior disclosure of identities: the protocol participants learn them in a way hidden to eavesdroppers.
Elastomeric polyacrylamide gels for high‐resolution electrophoresis of proteins (2000)

The inclusion of dextran in polyacrylamide crosslinked with N,N′-(1,2-dihydroxyethylene)bisacrylamide (DHEBA) produced elastomeric gels. Enhancement of the resolving power of the gel electrophoresis for sodium dodecyl sulfate-protein complexes (molecular mass from 14,400 to 97,400) was observed by using the elastomeric gels. Their effective pore sizes were smaller, compared with conventional polyacrylamide gels crosslinked with DHEBA at the same total monomer (T) and crosslinker (C) concentrations. The molecular sieving network of the elastomeric gel may be formed by crosslinked polyacrylamide and entangled dextran molecules. Copyright © 2000 John Wiley & Sons, Ltd.

Modeling Contact Angle Hysteresis on Chemically Patterned and Superhydrophobic Surfaces (2007)

We investigate contact angle hysteresis on chemically patterned and superhydrophobic surfaces, as the drop volume is quasistatically increased and decreased. We consider both two (cylindrical drops) and three (spherical drops) dimensions using analytical and numerical approaches to minimize the free energy of the drop. In two dimensions, we find, in agreement with other authors, a slip, jump, stick motion of the contact line. In three dimensions, this behavior persists, but the position and magnitude of the contact line jumps are sensitive to the details of the surface patterning. In two dimensions, we identify analytically the advancing and receding contact angles on the different surfaces, and we use numerical insights to argue that these provide bounds for the three-dimensional cases. We present explicit simulations to show that a simple average over the disorder is not sufficient to predict the details of the contact angle hysteresis and to support an explanation for the low contact angle hysteresis of suspended drops on superhydrophobic surfaces.
Pharmacologic approaches to the treatment of cocaine dependence. (1990)

When pharmacologic agents are considered in the treatment of cocaine addiction, the objective of such treatment--sustained abstinence--must be considered. Medication and medical approaches have been disappointing in the treatment of cocaine overdose. The central neurobiologic mechanism(s) involved in cocaine toxicity are poorly understood. Without a cocaine antagonist, pharmacologic approaches have been less than promising in preventing relapse. Various psychoactive medications have been tried in early cocaine abstinence, with some success.
[Neurological complications after vaccination against rabies as exemplified by 4 cases from Poznań province]. (1986)

The author reports 4 cases of neurological complications following vaccination with cerebral-type lyophilized vaccine. The cases were observed in the Province of Poznań in the period from January to April 1984, and the patients were men aged 41 to 60 years with various clinical syndromes: Landry's ascending paralysis, polyradiculoneuritis, polyneuritis and encephalopolyradiculoneuritis. The high frequency of these complications (about 3%) might have been due to the high susceptibility of the vaccinated population, or to technical errors in the production of the vaccine leading to obtaining of a vaccine bath with a high immunoallergogenicity which could trigger off the complication in persons with individual predisposition.
A guided tour of multiparameter full-waveform inversion with multicomponent data: From theory to practice (2013)

Building high-resolution models of several physical properties of the subsurface by multiparameter full waveform inversion (FWI) of multicomponent data will be a challenge for seismic imaging for the next decade. The physical properties, which govern propagation of seismic waves in visco-elastic media, are the velocities of the P- and S-waves, density, attenuation, and anisotropic parameters. Updating each property is challenging because several parameters of a different nature can have a coupled effect on the seismic response for a particular propagation regime (from transmission to reflection). This is generally referred to as trade-off or crosstalk between parameters. Moreover, different parameter classes can have different orders of magnitude or physical units and footprints of different strength in the wavefield, which can make the inversion poorly conditioned if it is not properly scaled.
Fabrication of femtosecond laser-induced Bragg gratings in amorphous and crystalline dielectric waveguides (2007)

Phase mask assisted fabrication of Bragg gratings in Ge-doped SMF-28 fiber with an ultrafast 800nm IR laser was first demonstrated in 2003. The wide variety of materials accessible to ultrafast laser modification allows for the fabricating of components that were not previously realizable with UV laser photosensitivity. Ultrafast fabricated gratings themselves have proven to have a number of common properties with UV induced gratings, and some unique elements. This paper will introduce phase mask assisted ultrafast infrared induced grating fabrication and some of their unique properties.
A comparison of monolithic background calibration in two time-interleaved analog-to-digital converters (2002)

Two background calibration methods for time-interleaved pipelined analog-to-digital converters are described and compared. One approach uses an extra ADC channel and analog calibration circuits; the other uses extra resolution and digital calibration circuits. Both approaches have been integrated in a 1-/spl mu/m CMOS process. The strengths and weaknesses of the two approaches are presented, and the measured data are compared.
Spectral Characteristics and Inhomogeneities near Active Regions of Double-Heterostructure (GaAl)As–GaAs Lasers with Stripe Geometry Configuration (1974)

It is shown experimentally that several types of spectra of double heterostructure (GaAl)As-GaAs lasers are connected with corresponding inhomogeneities in and around their active regions. i) Families of axial modes belonging to different transverse modes along the junction plane often show different axial mode spacings, indicating filamentary nature along the axial direction. This type of oscillation may be called "quasi-filamentary". ii) Families of axial modes in one transverse mode were also observed, which arise from the mode selection effect associated with sharp changes of the thickness of the active layer. iii) For some lasers, evidence is given that local boundaries rather than the heteroboundaries play an essential role. iv) The sustained pulsations having characteristics of the second order mode locking are connected with saturable absorption which arises from the existence of nonuniformity in the active region.
A Genome-wide Approach to Identify the Genes Involved in Biofilm Formation in E. coli (2008)

Biofilm forming cells are distinctive from the well-investigated planktonic cells and exhibit a different type of gene expression. Several new Escherichia coli genes related to biofilm formation have recently been identified through genomic approaches such as DNA microarray analysis. However, many others involved in this process might have escaped detection due to poor expression, regulatory mechanism, or genetic backgrounds. Here, we screened a collection of single-gene deletion mutants of E. coli named 'Keio collection' to identify genes required for biofilm formation. Of the 3985 mutants of non-essential genes in the collection thus examined, 110 showed a reduction in biofilm formation nine of which have not been well characterized yet. Systematic and quantitative analysis revealed the involvement of genes of various functions and reinforced the importance in biofilm formation of the genes for cell surface structures and cell membrane. Characterization of the nine mutants of function-unknown genes indicated that some of them, such as yfgA that genetically interacts with a periplasmic chaperone gene surA together with yciB and yciM, might be required for the integrity of outer membrane.
SiGe HBT linear-in-dB high dynamic range RF envelope detectors and wideband high linearity amplifiers (2010)

This research work aims on exploiting SiGe HBT technologies in high dynamic range wideband RF linear-in- dB envelope detectors and linear amplifiers. First, an improved all-npn broadband highly linear SiGe HBT differential amplifier is presented based on a variation of Caprio's Quad. A broadband linear amplifier with 46dBm OIP₃ at 20MHz, 34dBm OIP₃ at 1GHz, 6dB noise figure and 10.3dBm P₁dB is demonstrated. Second, an improved exact dynamic model of a fast-settling linear-in-dB Automatic Gain Control (AGC) circuit is developed. Based on this, a wideband linear-in-dB RF envelope detector is implemented in TowerJazz Semiconductor 0.18 [Mu]m SBC BiCMOS process with 2.5GHz bandwidth and 50dB dynamic range

PAMPAS: real-valued graphical models for computer vision (2003)

Probabilistic models have been adopted for many computer vision applications, however inference in high-dimensional spaces remains problematic. As the state-space of a model grows, the dependencies between the dimensions lead to an exponential growth in computation when performing inference. Many common computer vision problems naturally map onto the graphical model framework; the representation is a graph where each node contains a portion of the state-space and there is an edge between two nodes only if they are not independent conditional on the other nodes in the graph. When this graph is sparsely connected, belief propagation algorithms can turn an exponential inference computation into one, which is linear in the size of the graph. However belief propagation is only applicable when the variables in the nodes are discrete-valued or jointly represented by a single multivariate Gaussian distribution, and this rules out many computer vision applications. This paper combines belief propagation with ideas from particle filtering; the resulting algorithm performs inference on graphs containing both cycles and continuous-valued latent variables with general conditional probability distributions. Such graphical models have wide applicability in the computer vision domain and we test the algorithm on example problems of low-level edge linking and locating jointed structures in clutter.
Single-chip detector for electron spin resonance spectroscopy (2008)

We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complementary metal-oxide-semiconductor technology. The implemented detection method is based on the measurement of the variation of the frequency of the integrated LC oscillator as a function of the applied static magnetic field, caused by the presence of a resonating sample placed over the inductor of the LC-tank circuit. The achieved room temperature spin sensitivity is about 10(10) spinsGHz(12) with a sensitive volume of about (100 microm)(3).

Cell Transplantation Therapy for Stroke (2007)

No treatment currently exists to restore lost neurological function after stroke. A growing number of studies highlight the potential of stem cell transplantation as a novel therapeutic approach for stroke. In this review we summarize these studies, discuss potential mechanisms of action of the transplanted cells, and emphasize the need to determine parameters that are critical for transplantation success.
Pilus- gonococcal variants. Evidence for multiple forms of piliation control. (1985)

Pilus+ to pilus- transitions of gonococci (Gc) that involve rearrangement of pilin gene DNA yield the P-n phenotype, which is incapable of reversion (to pilus+). Reversion to pilus+ is found for nonpiliated Gc that have undergone no apparent pilin gene rearrangement. Among the reverting, nonpiliated Gc, two distinct phenotypes (P-rp- and P-rp+) occur and are differentiated according to their synthesis (or lack) of pilin subunits; both P-rp- and P-rp+ Gc contain pilin-specific mRNA. The occurrence of these different pilus- phenotypes strongly suggests that several mechanisms can account for changes in the piliation status of Gc; one of these involves pilin gene rearrangement but the others apparently operate at posttranscriptional levels. Reverting pilus- Gc may have a pathogenic advantage in being able to reversibly alter their host cell adherence-promoting surface properties through high frequency transitions in piliation status.
Identification of the Zinc Ligands in Cobalamin-Independent Methionine Synthase (MetE) from <i>Escherichia coli</i> (1999)

Cobalamin-independent methionine synthase (MetE) from Escherichia coli catalyzes the transfer of a methyl group from methyltetrahydrofolate to homocysteine to form tetrahydrofolate and methionine. It contains 1 equiv of zinc that is essential for its catalytic activity. Extended X-ray absorption fine structure analysis of the zinc-binding site has suggested tetrahedral coordination with two sulfur (cysteine) and one nitrogen or oxygen ligands provided by the enzyme and an exchangeable oxygen or nitrogen ligand that is replaced by the homocysteine thiol group in the enzyme−substrate complex [González, J. C., Peariso, K., Penner-Hahn, J. E., and Matthews, R. G. (1996) Biochemistry 35, 12228−34]. Sequence alignment of MetE homologues shows that His641, Cys643, and Cys726 are the only conserved residues. We report here the construction, expression, and purification of the His641Gln, Cys643Ser, and Cys726Ser mutants of MetE. Each mutant displays significantly impaired activity and contains less than 1 equiv of zinc upon purification. Furthermore, each mutant binds zinc with lower binding affinity (Ka ≈ 1014 M-1) compared to the wild-type enzyme (Ka > 1016 M-1). All the MetE mutants are able to bind homocysteine. X-ray absorption spectroscopy analysis of the zinc-binding sites in the mutants indicates that the four-coordinate zinc site is preserved but that the ligand sets are changed. Our results demonstrate that Cys643 and Cys726 are two of the zinc ligands in MetE from E. coli and suggest that His641 is a third endogenous ligand. The effects of the mutations on the specific activities of the mutant proteins suggest that zinc and homocysteine binding alone are not sufficient for activity; the chemical nature of the ligands is also a determining factor for catalytic activity in agreement with model studies of the alkylation of zinc-thiolate complexes.

A resource management framework for multi-tier service delivery in autonomic virtualized environments (2008)

Large data centers usually host many different services on a shared computing infrastructure, for which on-demand resource management is necessary to maximize providers' revenues by meeting service quality targets at least operational cost. This paper presents a novel architecture of autonomic resource management framework based on virtualized service-oriented computing (SOC) environment. A non-linear continuous optimization problem is defined for adaptive resource allocation and a model-based approach is adopted to solve this problem. Different from traditional approaches, the analytic model we established provides probabilistic performance guarantees and considers non-steady-state behavior assisted by admission control. Results of prototype experiments demonstrate that the performance of multiple services has been greatly improved by taking advantage of fine-grained resource sharing, while incurring much lower resource usage cost. Also, differentiated service qualities could be provided to different client classes through our dynamic resource allocation scheme.
Placebo response in depression (2002)

With its naturally fluctuating course, depression is a highly placebo-responsive condition: mean placebo response rates in antidepressant clinical trials are 30% to 40%. We review the history and terminology of placebo and the proposed mechanisms underlying the placebo response, including the physician-patient relationship and biological, sociocultural, and treatment situation factors. We identify the predictors and patterns of placebo response in depressed patients, both within and outside of the clinical trial context, and differentiate between true drug response and placebo pattern response. We discuss the strategies now being advanced to minimize the placebo response given the increased placebo drift reported in recent trials, and the ethical guidelines governing placebo administration. Potential areas for future research include the identification of biological markers of placebo response, such as functional neuroimaging and quantitative electroencephalography, the development and testing of more sophisticated, alternative research designs, and the design of valid biological tools to assess antidepressant efficacy.
Multichannel texture analysis using localized spatial filters (1990)

A computational approach for analyzing visible textures is described. Textures are modeled as irradiance patterns containing a limited range of spatial frequencies, where mutually distinct textures differ significantly in their dominant characterizing frequencies. By encoding images into multiple narrow spatial frequency and orientation channels, the slowly varying channel envelopes (amplitude and phase) are used to segregate textural regions of different spatial frequency, orientation, or phase characteristics. Thus, an interpretation of image texture as a region code, or carrier of region information, is emphasized. The channel filters used, known as the two-dimensional Gabor functions, are useful for these purposes in several senses: they have tunable orientation and radial frequency bandwidths and tunable center frequencies, and they optimally achieve joint resolution in space and in spatial frequency. By comparing the channel amplitude responses, one can detect boundaries between textures. Locating large variations in the channel phase responses allows discontinuities in the texture phase to be detected. Examples are given of both types of texture processing using a variety of real and synthetic textures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
