Subband Adaptive Filtering: Theory and Implementation (2009)

Subband adaptive filtering is rapidly becoming one of the most effective techniques for reducing computational complexity and improving the convergence rate of algorithms in adaptive signal processing applications. This book provides an introductory, yet extensive guide on the theory of various subband adaptive filtering techniques. For beginners, the authors discuss the basic principles that underlie the design and implementation of subband adaptive filters. For advanced readers, a comprehensive coverage of recent developments, such as multiband tapweight adaptation, delayless architectures, and filterbank design methods for reducing bandedge effects are included. Several analysis techniques and complexity evaluation are also introduced in this book to provide better understanding of subband adaptive filtering. This book bridges the gaps between the mixeddomain natures of subband adaptive filtering techniques and provides enough depth to the material augmented by many MATLAB functions and examples. Key Features: Acts as a timely introduction for researchers, graduate students and engineers who want to design and deploy subband adaptive filters in their research and applications. Bridges the gaps between two distinct domains: adaptive filter theory and multirate signal processing. Uses a practical approach through MATLAB-based source programs on the accompanying CD. Includes more than 100 M-files, allowing readers to modify the code for different algorithms and applications and to gain more insight into the theory and concepts of subband adaptive filters. Subband Adaptive Filtering is aimed primarily at practicing engineers, as well as senior undergraduate and graduate students. It will also be of interest to researchers, technical managers, and computer scientists.
MALIGNANCIES IN THE AIDS PATIENT: NATURAL HISTORY, TREATMENT STRATEGIES, AND PRELIMINARY RESULTS (1984)

Almost 40% of the 3000 US patients with acquired immunodeficiency syndrome (AIDS) have a malignancy at the time of reporting, and the incidence of AIDS patients who develop a malignancy during the course of the disease may be 65-70%. 2 types of malignancies have been noted with increased frequency in AIDS victims: Kaposi's sarcoma and malignant lymphomas. About 35% of all AIDS patients and 50% of homosexual or bisexual victims have developed Kaposi's sarcoma, and those with coincident opportunistic infection have 2.5 times the mortality of those without such infection. There are 2 essential features to the histopathology of Kaposi's sarcoma: 1) vascular proliferation and 2) spindle-shaped neoplastic cells in a network of reticulin fibers that appear to be of endothelial origin. The treatment of the epidemic form of Kaposi's sarcoma has not been successful, and the projected 2-year survival is only 30%. The causes of death in the majority of such patients are overwhelming opportunistic infections, especially cytomegalovirus and Pneumocystis carinii, and irreversible cachexia and wasting. Interferon therapy has had a beneficial effect in patients with disease limited to skin, with T4/T8 ratios over 0.5, and without a prior history of opportunistic infection; however, there is no evidence that interferon exerts any beneficial effects on the underlying immune defects. An aggressive 6-drug combination chemotherapy regimen has been tried on patients whose tumors appeared to be life-threatening and was effective in controlling the Kaposi's sarcoma, but again did not appreciably alter immune parameters. Several other approaches to the treatment of epidemic Kaposi's sarcoma are under evaluation, including gamma interferon, interleukin-2, and plasmapheresis. Patients who develop malignant lymphomas require combined treatment with central nervous system radiation and systemic combination chemotherapy. There is no evidence that the antitumor responses obtained in AIDS-related malignancies translate into survival advantages to the AIDS victim.
Workshop 3: IEEE ISMAR 2012 workshop on tracking methods and applications (TMA) (2012)

The focus of this workshop is on presenting, discussing and demonstrating recent tracking methods and applications that work well in practice and that show some superiority over state-of-the-art methods. Rather than focusing on pure novelty, this workshop encourages presentations that concentrate on complete systems and integrated approaches.
Genetic manipulation of pathogenic Leptospira: CRISPR interference (CRISPRi)-mediated gene silencing and rapid mutant recovery at 37 °C (2021)

Leptospirosis is a neglected, widespread zoonosis caused by pathogenic species of the genus Leptospira, and is responsible for 60,000 deaths per year. Pathogenic mechanisms of leptospirosis remain poorly understood mainly because targeted mutations or gene silencing in pathogenic Leptospira continues to be inherently inefficient, laborious, costly and difficult to implement. In addition, pathogenic leptospires are highly fastidious and the selection of mutants on solid agar media can take up to 6 weeks. The catalytically inactive Cas9 (dCas9) is an RNA-guided DNA-binding protein from the Streptococcus pyogenes CRISPR/Cas system and can be used for gene silencing, in a strategy termed CRISPR interference (CRISPRi). Here, this technique was employed to silence genes encoding major outer membrane proteins of pathogenic L. interrogans. Conjugation protocols were optimized using the newly described HAN media modified for rapid mutant recovery at 37 °C in 3% CO<sub>2</sub> within 8 days. Complete silencing of LipL32 and concomitant and complete silencing of both LigA and LigB outer membrane proteins were achieved, revealing for the first time that Lig proteins are involved in pathogenic Leptospira serum resistance. Gene silencing in pathogenic leptospires and rapid mutant recovery will facilitate novel studies to further evaluate and understand pathogenic mechanisms of leptospirosis.

We discuss a question of Grothendieck for profinite completions and its analogue for true prosoluble and true pronilpotent completions. 1. Introduction. 2. Completion with respect to a directed set of normal subgroups. 3. Universal property. 4. Examples of directed sets of normal subgroups. 5. True prosoluble completions. 6. Examples. 7. On the true prosoluble and the true pronilpotent analogues of Grothendieck's problem.
Signal reconstruction from phase or magnitude (1980)

In this paper, we develop a set of conditions under which a sequence is uniquely specified by the phase or samples of the phase of its Fourier transform, and a similar set of conditions under which a sequence is uniquely specified by the magnitude of its Fourier transform. These conditions are distinctly different from the minimum or maximum phase conditions, and are applicable to both one-dimensional and multidimensional sequences. Under the specified conditions, we also develop several algorithms which may be used to reconstruct a sequence from its phase or magnitude.
Insight into interface electrical properties of metal–oxide–semiconductor structures fabricated on Mg-implanted GaN activated by ultra-high-pressure annealing (2022)

GaN-based metal–oxide–semiconductor (MOS) devices, such as n- and p-type capacitors and inversion- and accumulation-type p-channel field effect transistors (MOSFETs), were fabricated by Mg-ion implantation and ultra-high-pressure annealing (UHPA) under 1-GPa nitrogen pressure. Even though UHPA was conducted at 1400 °C without protective layers on GaN surfaces, n-type MOS capacitors with SiO2 gate dielectrics formed on non-ion-implanted regions exhibited well-behaved capacitance–voltage characteristics with negligible hysteresis and frequency dispersion, indicating distinct impact of UHPA in suppressing surface degradation during high-temperature annealing. Efficient activation of the implanted Mg dopants and reasonable hole accumulation at the SiO2/GaN interfaces were also achieved for p-type capacitors by UHPA, but the fabricated inversion- and accumulation-type p-channel GaN MOSFETs were hardly turned on. The findings reveal extremely low hole mobility at GaN MOS interfaces and suggest an intrinsic obstacle for the development of GaN-based MOS devices.

Adhesion of Polymer Vesicles (2005)

The adhesion and bending modulus of polybutadiene-poly(ethylene oxide) block copolymer vesicles made from a bidisperse mixture of polymers is measured using micropipette aspiration. The adhesion energy between biotinylated vesicles and avidin beads is modeled by incorporating the extension of the adhesive ligands above the surface brush of the vesicle according to the blob model of bidisperse polymer mixtures of Komura and Safran assuming the polymer brush at the surface of the vesicle is compact. The same model accurately reproduces the scaling of the bending modulus with polymer composition.

A mutant ofEscherichia colitemperature sensitive in the biosynthesis ofS-adenosylmethionine (1987)

&lt;it&gt;S&lt;/it&gt;-Adenosylmethionine (SAM) is synthesized in vitro by SAM synthetase, which is coded for by the &lt;it&gt;metK&lt;/it&gt; gene of &lt;it&gt;Escherichia coli&lt;/it&gt;. Since &lt;it&gt;E. coli&lt;/it&gt; cells are impermeable to SAM it has been impossible to obtain mutants which require SAM for growth. The finding that SAM is required for regulating methionine biosynthesis was used to select &lt;it&gt;metK&lt;/it&gt; mutants which have the phenotype of resistance to methionine analogues. These mutants show reduced SAM synthesis in vitro, and a lower level of intracellular SAM. However, as all these mutants can grow, without added SAM, the block in SAM synthesis must be incomplete. To try to block SAM synthesis more completely we combined temperature-sensitive &lt;it&gt;metK&lt;/it&gt; mutation with a block in the synthesis of cystathionine (&lt;it&gt;metA&lt;/it&gt;), a precursor that supports only slow growth because of slow entry. At the non-permissive temperature for &lt;it&gt;metK&lt;/it&gt; these double mutants could grow on methionine but not on cystathionine, in correlation with the greatly reduced intracellular level of SAM. This result indicates that it is possible to reduced intracellular SAM concentrations to levels which are low enough to prevent growth of &lt;it&gt;E. coli&lt;/it&gt;. Moreover, since the mutation responsible for the reduction in SAM level is in the &lt;it&gt;metK&lt;/it&gt; gene, it is suggested that SAM synthetase is the enzyme which catalyses SAM biosynthesis in &lt;it&gt;E. coli&lt;/it&gt; cells.
Exhaled nitric oxide is reduced in infants with rhinorrhea (2004)

In infants, the effect of colds and other respiratory tract infections (RTI) on exhaled nitric oxide (FE(NO)) is not clear. In this study, we measured FE(NO) in 24 infants (14 boys) who presented with rhinorrhea, with or without cough but not wheeze. Twelve of these infants had a history of recurrent wheeze. Levels were compared with a group of 23 healthy infants (13 boys). Further, 8 infants (5 with a history of recurrent wheeze) with rhinorrhea were tested after symptoms had resolved. Infants with rhinorrhea had significantly lower FE(NO) than the healthy infants (11.9 vs. 23.8 ppb, respectively, P < 0.0007). Levels increased from 7.5 ppb to 34.1 ppb in the 8 infants tested with and without symptoms (P = 0.0002). Infants with rhinorrhea have reduced FE(NO), irrespective of their respiratory history.
In vivomodels of human airway epithelium repair and regeneration (2005)

Despite an efficient defence system, the airway surface epithelium, in permanent contact with the external milieu, is frequently injured by inhaled pollutants, microorganisms and viruses. The response of the airway surface epithelium to an acute injury includes a succession of cellular events varying from the loss of the surface epithelium integrity to partial shedding of the epithelium or even to complete denudation of the basement membrane. The epithelium has then to repair and regenerate to restore its functions. The in vivo study of epithelial regeneration in animal models has shown that airway epithelial cells are able to dedifferentiate, spread, migrate over the denuded basement membrane and progressively redifferentiate to reconstitute a functional respiratory epithelium after several weeks. Humanised tracheal xenograft models have been developed in immunodeficient nude and severe combined immunodeficient (SCID) mice in order to mimic the natural regeneration process of the human airway epithelium and to analyse the cellular and molecular events involved during the different steps of airway epithelial reconstitution. These models represent very powerful tools for analysing the modulation of the biological functions of the epithelium during its regeneration. They are also very useful for identifying stem/progenitor cells of the human airway epithelium. A better knowledge of the mechanisms involved in airway epithelium regeneration, as well as the characterisation of the epithelial stem and progenitor cells, may pave the way to regenerative therapeutics, allowing the reconstitution of a functional airway epithelium in numerous respiratory diseases, such as asthma, chronic obstructive pulmonary diseases, cystic fibrosis and bronchiolitis.

These articles can be divided into the following topics: a) models for innovation and technological commercialization, b) the ethical and legal consequences of the emergence of new technologies, c) research on novel technologies and methods, and d) the difficulties involved in peer review and scientific assessment. The articles shed light on the effects of technological innovation and commercialization on scientific ethical regulation, the establishment of legal standards for the protection of intellectual property, and the development of financial models.
Enhanced Film Cooling Effectiveness With New Shaped Holes (2010)

Gas Turbine Engines operate at temperatures higher than current material temperature limits. This necessitates cooling the metal through internal or external means and/ or protecting the metal with coatings that have higher material limits. Film cooling is one of the major technologies allowing today’s gas turbines to operate at extremely high turbine inlet temperatures, consequently higher power density, and extend the cooled components life. Film cooling is a technique where a coolant is blown over the surface exposed to hot gas and a film of low temperature gas is maintained that protects the metal surface from the hot gas. The application of effective film-cooling techniques provides the first and best line of defense for hot gas path surfaces against the onslaught of extreme heat fluxes, serving to directly reduce the incident convective heat flux on the surface. The effectiveness of film cooling methods depends on the blowing ratio, shape of the cooling holes, and geometrical parameters such as the area ratio and diffusion angle. Film cooling is performed almost exclusively through the use of discrete holes. The holes can be of round or other shaped. A detailed study of the literature shows that the fan shaped has higher effectiveness when compared to other shapes. In this study a number of cooling hole shapes are evaluated numerically using the Computational Fluid Dynamics (CFD) tool ANSYS-CFX-11.0 with the objective of improving cooling effectiveness under a favorable pressure gradient main flow. In order to delineate the effects of shape from that of diffusion, a constant area ratio is assumed first. In the next set of analyses the effect of hole exit diffusion is considered. Results are presented in terms of surface temperatures and adiabatic effectiveness at three different blowing ratios for the different film cooling hole shapes analyzed. Comparison is made with reference to the fan shaped film cooling hole with forward and lateral angles of 10/10/10 degree respectively. Hole shapes that show improvement over the fan shaped hole are identified and optimized.
Endurance training and improved aerobic capacity after traumatic brain injury (2010)

The purpose of this study was to assess the feasibility and effectiveness of an endurance training program in patients who had sustained a traumatic brain injury (TBI) and were in the post-acute recovery phase. Methods: Thirteen patients gave written consent. Inclusion criteria were: ability to ambulate safely on a treadmill at a minimal speed of 1.6kph (1.0mph), no overt cardiovascular disease, ability to follow 2-step commands, and compliance with the expired gas collection apparatus. A modified Balke protocol was used. Speed was gradually increased to the safest possible speed in the first two minutes at 1% incline. Incline was then increased 2% per minute until two of three peak criteria (O2plateau, HR &amp;gt;90% age-predicted max, respiratory exchange ratio (RER) &amp;gt;1.15) or ambulation became unsafe. Multivariate comparisons were performed (alpha=0.05). Results: Peak O2improved (23.1sd7.6 vs 30.3sd6.9 mL/min/kg) (p&amp;lt;0.01). Peak HR and RER did not change. Submaximal ventilatory equivalents decreased. Conclusions: Despite the cognitive and behavioral challenges, patients were found to be compliant with properly prescribed aerobic exercise. Further randomized controlled trials are warranted in this population. TBI is a chronic disease and increased physical activity should be encouraged early in the rehabilitation process.
Low operating current and high temperature operationof650 nm AlGaInP visible laser diodes with real refractiveindex guided self-aligned structure (1997)

High temperature operation at up to 90°C has been achieved in 650 nm-band AlGaInP visible laser diodes with a real refractive index guided self-aligned structure using an AlInP current blocking layer. The operating current is as low as 45 mA under CW operation at 60°C and the characteristic temperature is 120K from 20 to 60°C.
Topology of intermolecular nanostructures of adsorbed and liquid ethanol (2009)

Based on the combination of molecular-dynamic calculations with the graph theory, a method for identifying and remembering all molecular nanostructures observed in each snapshot of a molecular-dynamic trajectory; averaging data for any number of such snapshots, i.e., estimating averaged concentrations of associates (dimers, trimers, etc.); and determining the concentrations and structural characteristics (bond lengths, angles, etc.) of corresponding structures (e.g., chains, branched chains, cycles, etc.) in each group of the associates is developed for the first time. The method is implemented as a software package, which is applied for the topological analysis of adsorbed and liquid ethanol and molecular nanostructures of different substances occurring in adsorbed or liquid states.
Slanted Stixels: A Way to Represent Steep Streets (2019)

Abstract This work presents and evaluates a novel compact scene representation based on Stixels that infers geometric and semantic information. Our approach overcomes the previous rather restrictive geometric assumptions for Stixels by introducing a novel depth model to account for non-flat roads and slanted objects. Both semantic and depth cues are used jointly to infer the scene representation in a sound global energy minimization formulation. Furthermore, a novel approximation scheme is introduced in order to significantly reduce the computational complexity of the Stixel algorithm, and then achieve real-time computation capabilities. The idea is to first perform an over-segmentation of the image, discarding the unlikely Stixel cuts, and apply the algorithm only on the remaining Stixel cuts. This work presents a novel over-segmentation strategy based on a fully convolutional network, which outperforms an approach based on using local extrema of the disparity map. We evaluate the proposed methods in terms of semantic and geometric accuracy as well as run-time on four publicly available benchmark datasets. Our approach maintains accuracy on flat road scene datasets while improving substantially on a novel non-flat road dataset.
Do young women with tattoos have lower self-esteem and body image than their peers without tattoos? A non-verbal repertory grid technique approach (2019)

Available evidence regarding the reasons for people to acquire body markers such as tattoos is contradictory. The present study was designed to investigate the relationship between self-esteem and body image in young women with tattoos. To this end, the repertory grid technique (RGT) was adapted and used to assess differences between women with and without tattoos in terms of self-esteem and body image. Sixty young women with tattoos and sixty young women without (all aged 18-35 years), performed the Color RGT in order to evaluate the relationship between self-esteem and body image. Compared to women without tattoos, women with tattoos showed significantly lower self-esteem and displayed stronger relationships between three constructs: ideal body, ideal self and tattooed woman status. No significant differences in body image were detected between the two groups. Women with tattoos were characterized by an association between body image and self-esteem, while women without tattoos did not display such a correlation. Thus, it appears that links between self-esteem, ideal body, ideal self and constructs of "woman with tattoos" may play a role in tattooing behavior in young women.
Demand Reduction and Inefficiency in Multi-Unit Auctions (2014)

Auctions often involve the sale of many related goods: Treasury, spectrum and electricity auctions are examples. In multi-unit auctions, a bid for one unit may affect payments for other units won, giving rise to an incentive to shade bids differently across units. We establish that such differential bid shading results generically in ex post inefficient allocations in the uniform-price and pay-as-bid auctions. We also show that, in general, the efficiency and revenue rankings for the two formats are ambiguous. However, in settings with symmetric bidders, the pay-as-bid auction often outperforms. In particular, with diminishing marginal utility, symmetric information and linearity, it yields greater expected revenues. We explain the rankings through multi-unit effects, which have no counterparts in auctions with unit demands. We attribute the new incentives separately to multi-unit but constant marginal utility and diminishing marginal utility.
