Multi-level data transmission over mobile radio channels (1990)

Describes how the transparent tone in band technique (TTIB) can be optimally used for data transmission. This involves baseband spectral manipulations most effectively performed on a DSP device to generate a system which provides the required coherent carrier reference and also symbol timing information, independent of the modulation type. Results have previously been presented which demonstrated the feasibility of using TTIB based data transmission. These results were generated using a standard V29 telephone modem as the modulation source, with carrier recovery and bit timing synchronisation implemented by the modem. Significant improvements in performance have been made by utilising the full capabilities of the TTIB technique. The hardware implementation has also been greatly simplified to a single TMS 320C25 DSP device for both modulator and demodulator. >

Teachers' Attitudes Toward the Inclusion of Students with Autism and Emotional Behavioral Disorder (2011)

General education teachers have differing views about the inclusion of students with disabilities in mainstream classrooms. However, the type and severity of the children’s disabilities affect teachers’ willingness to accommodate certain students and their confidence that they will effectively manage their classroom. It has been reported that teachers have expressed concerns about having students with autism and emotional behavioral disorder in the general education setting because of the children’s lack of social skills, behavioral outbursts, modifications made to the curriculum, and lack of training and supports. Many instructors do not believe they are able to teach these populations effectively while simultaneously teaching a large group of typically developing students. Teachers’ attitudes toward their current student population with special needs dramatically affect the success and effectiveness of their instruction. Using a snowball sampling method, 25 general education teachers were surveyed regarding their willingness to include a child with autism and a student with EBD in their classroom to determine if there was a significant difference in their attitudes toward the disabilities.

Handbook of CCD Astronomy (2006)

Charge-Coupled Devices (CCDs) are the state-of-the-art detector in many fields of observational science. Updated to include all of the latest developments in CCDs, this second edition of the Handbook of CCD Astronomy is a concise and accessible reference on all practical aspects of using CCDs. Starting with their electronic workings, it discusses their basic characteristics and then gives methods and examples of how to determine these values. While the book focuses on the use of CCDs in professional observational astronomy, advanced amateur astronomers, and researchers in physics, chemistry, medical imaging, and remote sensing will also find it very valuable. Tables of useful and hard-to-find data, key practical equations, and new exercises round off the book and ensure that it provides an ideal introduction to the practical use of CCDs for graduate students, and a handy reference for more experienced users.
Wavelet Based Image Denoising Technique (2011)

This paper proposes different approaches of wavelet based image denoising methods. The search for efficient image denoising methods is still a valid challenge at the crossing of functional analysis and statistics. In spite of the sophistication of the recently proposed methods, most algorithms have not yet attained a desirable level of applicability. Wavelet algorithms are useful tool for signal processing such as image compression and denoising. Multi wavelets can be considered as an extension of scalar wavelets. The main aim is to modify the wavelet coefficients in the new basis, the noise can be removed from the data. In this paper, we extend the existing technique and providing a comprehensive evaluation of the proposed method. Results based on different noise, such as Gaussian, Poisson’s, Salt and Pepper, and Speckle performed in this paper. A signal to noise ratio as a measure of the quality of denoising was preferred.
Fc receptor regulation of protective immunity against <i>Chlamydia trachomatis</i> (2002)

The prevailing paradigm for designing potentially efficacious vaccines against the obligate intracellular bacterium, Chlamydia trachomatis, advocates regimens capable of inducing a mucosal antigen-specific T helper type 1 (Th1) response. However, recent reports indicate that rapid and efficient clearance of a secondary infection also requires certain B-cell functions. We investigated the hypothesis that Fc receptor (FcR)-mediated antibody effector mechanisms are important B-cell-related functions involved in controlling a chlamydial genital reinfection. Microbiological analysis of genital chlamydial infection in FcR knockout (FcRKO) mice lacking the activatory FcgammaRI (CD64) and FcRgammaIII (CD16), as well as the inhibitory FcgammaRIIB1 (CD32), revealed a greater intensity of secondary infection (i.e. bacterial shedding) in FcRminus sign/minus sign as compared to FcR+/+ mice; however, the course of the primary infection was indistinguishable in both animals. Pathologically, FcRKO mice suffered greater ascending infection than immunocompetent wild-type (WT) mice after a secondary infection. Immunological evaluation indicated that the presence of specific anti-chlamydial antibodies enhanced chlamydial antigen presentation for induction of a Th1 response by FcR+/+, but not FcRminus sign/minus sign, antigen-presenting cells. In addition, specific anti-chlamydial antibodies augmented both macrophage killing of infected epithelial cells by antibody-dependent cellular cytotoxicity (ADCC) and macrophage inhibition of productive growth of chlamydiae in co-cultures. These results indicate that B cells participate in anti-chlamydial immunity via FcR-mediated effector functions of antibodies, which are operative during reinfections. Such effector functions include ADCC, and possibly enhanced uptake, processing and presentation of chlamydial antigens for rapid induction of a Th1 response, all facilitating the early clearance of an infection. These findings suggest that a future anti-chlamydial vaccine should elicit both humoral and T-cell-mediated immune responses for optimal memory response and vaccine efficacy.
In vivo efficiency evaluation of a phage cocktail in controlling severe colibacillosis in confined conditions and experimental poultry houses (2010)

Infections caused by avian pathogenic Escherichia coli (APEC) cause important economic losses to poultry industry. The studies presented herein, aimed at investigating the in vivo performance of a cocktail of three phages in treating severe respiratory E. coli infections in experimentally contaminated birds and naturally infected flocks. Three lytic coliphages, phi F78E (Myoviridae), phi F258E (Siphoviridae) and phi F61E (Myoviridae) were combined in a 5.0 × 10(7)PFU/ml cocktail to be used in naturally APEC infected flocks (refractive to antibiotherapy). Experimentally infected birds were treated with phi F78E at two different titres (10(7)PFU/ml and 10(9)PFU/ml). Phage administration was performed orally and by spray, in a single application. The morbidity, mortality and pathology scores were compared with control birds not receiving phage therapy. The results revealed that the success of phage therapy in experimental rooms was dosage dependent, being 10(7)PFU/ml not enough to treat the infected chickens whereas a concentration of 10(9)PFU/ml of phi F78E allowed a decrease of 25% and 43% in chickens' mortality and morbidity, respectively. In the large scale experiments, the results obtained showed a remarkable efficacy of the low titre phage cocktail (10(7)PFU/ml) in decreasing the flocks' mortality to levels below 0.5% in no more than 3 weeks, with no recidivism. Based on the results we can conclude that phage treatment is a valuable alternative to control APEC infections in poultry.
Testing exchangeability on-line (2003)

The majority of theoretical work in machine learning is done under the assumption of exchangeability: essentially, it is assumed that the examples are generated from the same probability distribution independently. This paper is concerned with the problem of testing the exchangeability assumption in the on-line mode: examples are observed one by one and the goal is to monitor on-line the strength of evidence against the hypothesis of exchangeability. We introduce the notion of exchangeability martingales, which are online procedures for detecting deviations from exchangeability; in essence, they are betting schemes that never risk bankruptcy and are fair under the hypothesis of exchangeability. Some specific exchangeability martingales are constructed using Transductive Confidence Machine. We report experimental results showing their performance on the USPS benchmark data set of hand-written digits (known to be somewhat heterogeneous); one of them multiplies the initial capital by more than 10 18; this means that the hypothesis of exchangeability is rejected at the significance level 10 −18. 1.
Synthesis of Silver Nanoparticles Embedded Electrospun PAN Nanofiber Thin-Film Composite Forward Osmosis Membrane to Enhance Performance and Antimicrobial Activity (2018)

Enhancing antimicrobial activity is an effective strategy to mitigate membrane biofouling. In this study, an antimicrobial electrospun polyacrylonitrile (PAN) nanofiber mat decorated with in situ synthesized silver nanoparticles (AgNPs) was developed as support for a thin-film composite forward osmosis (FO) membrane. Effects of AgNPs on the physicochemical properties, water flux, reverse salt flux, and antimicrobial activity of the FO membrane were investigated, and also the antimicrobial mechanism was explored. Results showed AgNPs were monodisperse in the nanofibers, and the Ag/PAN nanofiber support (Ag/PAN-NFS) had a scaffold-like structure which could reduce internal concentration polarization. The Ag/PAN-NFS supported thin-film nanocomposite (Ag/PAN-TFN) FO membrane demonstrated outstanding hydrophilicity, resulting in high water fluxes in both FO and PRO modes. The Ag/PAN-TFN FO membranes, even the one with the lowest silver content of 0.5 wt %, exhibited excellent antibacterial activities for E. coli (96%) and S. aureus (92%), which was mainly due to the Ag+-species released into the solution.

Understanding and Managing Large B Cell Lymphoma Relapses after Chimeric Antigen Receptor T Cell Therapy (2019)

Most patients with large cell lymphoma are cured with frontline chemoimmunotherapy. For individuals with refractory disease and those who relapse after conventional therapies, chimeric antigen receptor (CAR) T cells are an important treatment option and have led to remissions in otherwise refractory patients. In the pivotal trials, durable responses were achieved in approximately 40% to 50% of patients treated with axicabtagene ciloleucel, tisagenlecleucel, or lisocabtagene maraleucel, indicating that many patients will require subsequent treatment. Failure after CAR T cell therapy is caused by a variety of factors that can be divided into 3 broad categories: tumor intrinsic factors, other host factors, and inadequacies of the CAR T cells. Within this framework, this article reviews possible mechanisms of treatment failures and, based on the timing of relapse, considers potential salvage therapies and opportunities for future clinical studies.
Sign (2006)

FigureA 43-year-old man is brought to the ED by fire rescue. His neighbor called 911 because he had not been eating well since a minor car crash the week before. The patient is a poor historian who denies any complaints. He denies pain, fever, abdominal pain, nausea, vomiting, headache, and weakness. It is difficult to obtain a history because of a language barrier. He emigrated from Uganda seven years before, and denies any previous medical problems, IV drug abuse, AIDS-defining illnesses, or psychiatric history. He is afebrile and his physical exam, including neurological evaluation, are unremarkable except that he intermittently follows verbal commands, is oriented only to self, and has a flat affect. Lab results revealed a white blood count of 2.7 thou/U with 29% lymphocytes, platelets 118 thou/U, and a normal Chem 10 profile. Head CT without contrast demonstrates multiple areas of abnormal low density consistent with edema. (See photo.) A head CT scan with contrast is then ordered. What do you expect to see on the head CT? What is the suspected diagnosis? How would you treat this patient?Figure
Strong coupling of a spin qubit to a superconducting stripline cavity (2012)

We study electron-spin-photon coupling in a single-spin double quantum dot embedded in a superconducting stripline cavity. With an external magnetic field, we show that either a spin-orbit interaction (for InAs) or an inhomogeneous magnetic field (for Si and GaAs) could produce a strong spin-photon coupling, with a coupling strength of the order of 1 MHz. With an isotopically purified Si double dot, which has a very long spin coherence time for the electron, it is possible to reach the strong-coupling limit between the spin and the cavity photon, as in cavity quantum electrodynamics. The coupling strength and relaxation rates are calculated based on parameters of existing devices, making this proposal experimentally feasible.
Intelligence in epilepsy: A prospective study in children (1983)

A prospective study tested the stability of the IQ in children with seizure disorders. Seventy-two children with epilepsy underwent psychological evaluations within two weeks of initial diagnosis and yearly thereafter for an average of 4 years. Forty-five of the patients also had a nonepileptic sib evaluated in parallel. The mean IQ for all the children with epilepsy was 99.7 (+/- 20.2, standard deviation) at the time of the initial test, not significantly different from the siblings. This score did not change appreciably with time. Eight of the 72 epileptic patients (11.1%), however, had a persistent decrease in IQ of 10 points or more. These patients had a higher incidence of drug levels in the toxic range (p less than 0.001), their epilepsy was more difficult to control (p less 0.005), and their seizures began at an earlier age (p less than 0.05). Discriminant analysis is revealed that the number of drugs to which the patient became toxic and the age at seizure onset were the two best predictors of ultimate IQ. These two predictors correctly classified 71% of all patients as to whether their IQ would drop by 10 or more points during the test period, remain within 10 points of the initial test score, or increase by more than 10 points. Total number of seizures and seizure control were less good predictors, according to this method of analysis. The findings suggest that, in younger children in particular, total seizure control should not be achieved at the price of repeated episodes of drug toxicity.

Proteomic typing of amyloid deposits in systemic amyloidoses (2011)

Amyloidoses are characterized by the presence of extracellular amyloid deposits, constituted by fibrillar aggregates of misfolded proteins. Despite the similar morphologic appearance of fibrils, at least 28 different proteins have been detected as causative agents of human amyloidoses, 14 of which associated with systemic forms. Unequivocal typing of the amyloid deposits is a key step in the management of these diseases. Existing drawbacks of traditional, immunohistochemistry-based techniques have driven the search for alternative solutions for direct amyloid typing. Proteomics indicates the comprehensive study of the proteins in a biological sample, centered on analysis by mass spectrometry. The great potential of this approach in describing the composition of amyloid deposits and in studying the molecular features of the amyloidogenic precursors has become immediately clear and the introduction of proteomics in the clinical practice has revolutionized the field of amyloid typing. This review provides a critical overview of the various approaches that have been proposed in this specific context, along with a brief description of the proteomic methods for assessment of the circulating amyloidogenic proteins.
Antibiosis and Antagonism of <i>Sclerotinia homoeocarpa</i> and <i>Drechslera poae</i> by <i>Pseudomonas fluorescens</i> Pf-5 In Vitro and In Planta (1997)

ABSTRACT Pseudomonas fluorescens strain Pf-5, which produces several antifun-gal metabolites, including the antibiotics pyoluteorin, pyrrolnitrin, and 2,4-diacetylphloroglucinol, was tested for its ability to inhibit Sclerotinia homoeocarpa (causal agent of dollar spot) and Drechslerapoae (causal agent of 'melting-out') in vitro and in turfgrass; Tn5 mutants with altered antibiotic production also were tested. Inhibition in vitro differed with the medium used, but both fungi generally were inhibited by Pf-5. In most cases, a mutant deficient in pyoluteorin but not pyrrolnitrin or 2,4-di-acetylphloroglucinol was as inhibitory as Pf-5, whereas a pyrrolnitrin-deficient mutant was less inhibitory than Pf-5 in most fungus/medium combinations. High-performance liquid chromatography analysis of culture extracts showed that bacterial genotype and nutrition have an interactive effect on antibiotic production, such that conditions causing an increase in one antibiotic may increase or decrease another. The purported deficiencies for the pyrrolnitrin- and pyoluteorin-deficient mutants were confirmed. In S. homoeocarpa-infested grass clippings incubated in a moist chamber, Pf-5 reduced mycelial growth, whereas the pyrrolnitrin-deficient mutant did not and the pyoluteorin-deficient mutant was intermediate. In greenhouse experiments, Pf-5 reduced dollar spot disease incidence in bentgrass and bluegrass when sprayed over inoculated turf. In grass clippings infested with D. poae and incubated in a moist chamber under favorable conditions for spore production, Pf-5 did not reduce significantly the number of spores produced compared with the non-treated control. However, Pf-5 reduced melting-out disease incidence and severity in bluegrass inoculated with spores of D. poae under greenhouse conditions.

Single robot search for a stationary object in an unknown environment (2014)

In this article we introduce the problem of finding an optimal path in order to find a stationary object placed in the environment whose map is not a-priory known. At first sight the problem seems to be similar to exploration which has been thoroughly studied by the robotic community. We show that a general framework for search can be derived from frontier-based exploration, but exploration strategies for selection of a next goal to which navigate a robot cannot be simply reused. We present three goal selection strategies (greedy, traveling salesmen based, and traveling deliveryman based) and statistically evaluate and discuss their performance for search in comparison to exploration.
