A New Approach to Extract Formant Instantaneous Characteristics for Speaker Identification (2009)

This article presents a new approach to extract formant instantaneous characteristics (FIC) parameters for speaker identifi- cation (SI). On the one hand, FIC could be derived from time-frequency description of speech signal in the Hilbert-Huang Transform (HHT). HHT is a powerful tool to analyze non-stationary signal and consists of sifting procedure of empirical mode decom- position (EMD) and the Hilbert Transform (HT). The sifting pro- cedure of EMD is to get intrinsic mode functions (IMF), so it is significant to determine all the instantaneous information from nonlinear or non-stationary signals like speech signals. This could be achieved directly through HT yet. On the other hand, a lot of in- formation comprised in formant is not only reflection of speech contents but also speakers' individual features, so that have to get finer formant properties. Compared with traditional methods, the FIC of extracting by HHT is able to describe fine formant instan- taneous information in detail. These FIC parameters are a class of reflections of speaker's individual features from both glottal wave and vocal tract. Finally, different kinds of FIC parameters were combined to MFCC to form a plurality of experimental parameters for SI based on a Gaussian mixture model (GMM). And results show that FIC parameters play a compensating role to MFCC in SI, with one of improved relative rate up to 11.96%.

Viral inactivation in hemotherapy: systematic review on inactivators with action on nucleic acids (2012)

The aim of this study was to conduct a systematic review on the photoinactivators used in hemotherapy, with action on viral genomes. The SciELO, Science Direct, PubMed and Lilacs databases were searched for articles. The inclusion criterion was that these should be articles on inactivators with action on genetic material that had been published between 2000 and 2010. The key words used in identifying such articles were "hemovigilance", "viral inactivation", "photodynamics", "chemoprevention" and "transfusion safety". Twenty-four articles on viral photoinactivation were found with the main photoinactivators covered being: methylene blue, amotosalen HCl, S-303 frangible anchor linker effector (FRALE), riboflavin and inactin. The results showed that methylene blue has currently been studied least, because it diminishes coagulation factors and fibrinogen. Riboflavin has been studied most because it is a photoinactivator of endogenous origin and has few collateral effects. Amotosalen HCl is effective for platelets and is also used on plasma, but may cause changes both to plasma and to platelets, although these are not significant for hemostasis. S-303 FRALE may lead to neoantigens in erythrocytes and is less indicated for red-cell treatment; in such cases, PEN 110 is recommended. Thus, none of the methods for pathogen reduction is effective for all classes of agents and for all blood components, but despite the high cost, these photoinactivators may diminish the risk of blood-transmitted diseases.
The "Vagabond" wireless microphone system (1954)

A cable-less microphone system has been developed, Designed for general public address use, the system utilizes inductioncoupling between the transmitter and receiver, and requires no license. The subminiature transmitter is completely contained in a stick type microphone housing. It consists of a microphone, a five-tube, printed circuit frequency-modulated transmitter, a self-contained antenna inductor, and batteries, and weighs less than one pound. The system gives excellent performance with operating areas up to 5000 square feet. The development of the system and of the subminiature transmitter is discussed and the performance of the induction system is evaluated.

The Influence of Genetics on Economic Efficiency of Broiler Chickens Growth (2013)

In this paper was studied the genetic effect on economic efficiency of broiler chickens growth, reared in intensive system on period of 42 days. The genetic material was represented of broiler chickens that belonged the hybrids „Ross-308” and „Cobb-500” with two groups („Ross-308”, LC-control group and „Cobb 500”, L1-experimental group). In the growth periods (starter, growth and finisher) chickens have received compound feed ad libitum with nutritional characteristics conforming to recommendations of the Aviagen Company. Broiler chickens and compound feed were weighed on each pen at: 1, 7, 14, 21, 28, 35 and 42 days, and was calculated: body weight gain (BWG), average daily gain (ADG) feed conversion ratio (FCR). Mortality was recorded daily. Thus, at the end of each growth period (14, 35 and 42 days), were calculated values for European Broiler Index (EBI) and European Production Efficiency Factor (EPEF). The highest values for EBI and EPEF were obtained at L1, and at LC situation was reversed. The economic efficiency of broiler chickens growth was positively influenced by the growth performance (BW, ADG and FCR) and the recorded viability. Although, the genotypes studied were reared under identical condition, the hybrid „Cobb-500” to registered slightly higher values for indices studied (P≤0.05), compared to the hybrid „Ross-308”.
Properties and Applications of Polyvinyl Alcohol, Halloysite Nanotubes and Their Nanocomposites (2015)

The aim of this review was to analyze/investigate the synthesis, properties, and applications of polyvinyl alcohol-halloysite nanotubes (PVA-HNT), and their nanocomposites. Different polymers with versatile properties are attractive because of their introduction and potential uses in many fields. Synthetic polymers, such as PVA, natural polymers like alginate, starch, chitosan, or any material with these components have prominent status as important and degradable materials with biocompatibility properties. These materials have been developed in the 1980s and are remarkable because of their recyclability and consideration of the natural continuation of their physical and chemical properties. The fabrication of PVA-HNT nanocomposites can be a potential way to address some of PVA's limitations. Such nanocomposites have excellent mechanical properties and thermal stability. PVA-HNT nanocomposites have been reported earlier, but without proper HNT individualization and PVA modifications. The properties of PVA-HNT for medicinal and biomedical use are attracting an increasing amount of attention for medical applications, such as wound dressings, drug delivery, targeted-tissue transportation systems, and soft biomaterial implants. The demand for alternative polymeric medical devices has also increased substantially around the world. This paper reviews individualized HNT addition along with crosslinking of PVA for various biomedical applications that have been previously reported in literature, thereby showing the attainability, modification of characteristics, and goals underlying the blending process with PVA.
Emerging Ideas: Prevention of Posttraumatic Arthritis Through Interleukin-1 and Tumor Necrosis Factor-alpha Inhibition (2010)

Background Despite surgical and mechanical stabilization of an acutely injured joint through ligament reconstruction, meniscus repair, or labral repair, the risk of posttraumatic arthritis remains high. Joint injury triggers three phases of pathogenic events: the early (acute) phase involves joint swelling, hemarthrosis, expression of inflammatory cytokines (especially interleukin-1 [IL-1] and tumor necrosis factor-α [TNF-α]), and biomarkers of cartilage catabolism; an intermediate phase is characterized by reduction of joint inflammation, ongoing joint catabolism, but no evidence yet for typical features of radiographic osteoarthritis (OA); and a late phase characterized by radiographic OA. Hypotheses We hypothesize that the early phase of acute knee injury represents a window of opportunity for providing biologic treatment to promote healing and to slow or prevent a subsequent cascade of destructive joint processes leading to OA. Proposed program We propose a phase II, randomized, placebo-controlled, double-blinded, clinical trial to treat acute knee injuries with intraarticular injection of an IL-1 inhibitor. Patient-centered outcomes will include pain reduction and improvement of knee function. MR imaging and measurement of biochemical markers will be monitored during the subsequent 2 years to determine if the structural response to injury can be reversed. Significance If this model is validated, modulation of the molecular pathways responsible for articular cartilage breakdown will augment current reconstructive procedures in the treatment of acute joint injuries and prevent the development of injury-related arthritis.

A new photorefractive (PR) material sensitized with a novel functional unit DiPBI is prepared based on the guest/host approach. This unique mixture exhibits strong absorption in the whole range of visible light. Moreover, the photorefractive performance as well as PR speed is improved by far compared to the widely used sensitizer PCBM.
A proposed information architecture for telehealth system interoperability (2003)

We propose an object-oriented information architecture for telemedicine systems that promotes secure 'plug-and-play' interaction between system components through standardized interfaces, communication protocols, messaging formats, and data definitions. In this architecture, each component functions as a black box, and components plug together in a "lego-like" fashion to achieve the desired device or system functionality.
Reducing the intermodulation distortion in multi-carrier microwave power amplifiers (2003)

This paper demonstrated the potential of the novel technique of the active predistortion linearisation. In comparison to the competitive methods, the proposed technique has the distinct advantage of reducing all the components of IMD distortion uniformly and over a wide frequency range, without significantly affecting the power efficiency.

Two novel fluorescent dyes based on perylene tetracarboxylic diimides and BODIPY were designed and synthesized. Significant features, such as longer wavelength absorption and emission, high fluorescence quantum yields, and strong electron accepting abilities, are observed for these compounds.
Digital signal processing systems architectures for image processing (1995)

The Coherent and Electro-Optics Research Group at Liverpool JMU have conceived and developed several digital signal processing (DSP) architectures for image processing. These have been centred on modern DSP products such as the T800 Transputer (Bibby, 1991), the TMS 320C30 (Hartley 1991), and the TMS320C40 (Kshirsagar et al., 1994). Central to the design and development of these systems has been the need to apply fast, relatively low cost hardware to industrial inspection problems presented to the research group.

Performance of microstrip patches incorporating a single shorting post (2002)

A thorough examination of the probe-fed circular patch incorporating a single shorting post is presented. The design methodology is summarized and comparisons with conventional probe-fed circular microstrip patches are presented. The two comparisons made are with patches designed with the same substrate, and thus considerably larger, as well as circular patches of the same size as the shorted patch. To achieve the latter comparison, the dielectric constant of the substrate for the conventional patches was significantly increased to reduce the overall size. This latter comparison is probably the most appropriate for applications where size is of primary concern. Finally, the performance trends of the shorted probe-fed microstrip circular patch are presented, illustrating the effects of substrate parameters on the overall characteristics of these antennas.
The Optimization of Simulation-Based Training Systems: A Review of Evaluations and Validation of Rule Bases. (1993)

The Optimization of Simulation-Based Training Systems (OSBATS) was designed to provide engineers involved in the concept formulation process for simulators and training devices, a tool with which to consider and tradeoff alternative features. OSBATS would enable engineers to tradeoff fidelity and instructional features in the context of a training strategy to obtain designs that minimize cost for desired performance levels. OSBATS consists of five modules: a simulator decision module, a training device media selection module, an instructional features module, a fidelity optimization module, and a resource allocation module. The heart of the OSBATS model resides in the expert system rule bases used in the instructional features and fidelity optimization modules to make decisions about instructional and fidelity features to be incorporated in the simulator designs. This report presents an overview of the OSBATS model and prototype software and summarizes efforts to validate its utility. An effort to validate the instructional features and fidelity rule bases is described in detail. The approach used to validate the rule bases was to select example tasks and use the OSBATS rule to produce recommendations for fidelity levels and instructional features.

Cs<sub>2</sub>AgBiX<sub>6</sub> (X = Br, Cl): New Visible Light Absorbing, Lead-Free Halide Perovskite Semiconductors (2016)

The double perovskites Cs2AgBiBr6 and Cs2AgBiCl6 have been synthesized from both solid state and solution routes. X-ray diffraction measurements show that both compounds adopt the cubic double perovskite structure, space group Fm3̅m, with lattice parameters of 11.2711(1) Å (X = Br) and 10.7774(2) Å (X = Cl). Diffuse reflectance measurements reveal band gaps of 2.19 eV (X = Br) and 2.77 eV (X = Cl) that are slightly smaller than the band gaps of the analogous lead halide perovskites, 2.26 eV for CH3NH3PbBr3 and 3.00 eV for CH3NH3PbCl3. Band structure calculations indicate that the interaction between the Ag 4d-orbitals and the 3p/4p-orbitals of the halide ion modifies the valence band leading to an indirect band gap. Both compounds are stable when exposed to air, but Cs2AgBiBr6 degrades over a period of weeks when exposed to both ambient air and light. These results show that halide double perovskite semiconductors are potentially an environmentally friendly alternative to the lead halide perovskite semiconductors.
Seminal vesicle secretion IV gene: allelic difference due to a series of 20-base-pair direct tandem repeats within an intron. (1983)

The rat seminal vesicle secretion IV (SVS IV) gene was isolated from a lambda Charon 4A library. The SVS IV gene transcription unit was found to be on one 3.3-kilobase (kb) EcoRI fragment. Restriction mapping and DNA sequence analysis demonstrated that the entire length of the SVS IV transcription unit is 1,930 base pairs (bp) and contains two introns. The 3.3-kb EcoRI fragment contains 144 bp of 5'-flanking region. At -113 bp from the presumed transcription initiation site an interesting structure with perfect dyad symmetry is noted. In another lambda clone, a 3.5-kb EcoRI fragment was isolated that contains the SVS IV gene and was shown to be identical to the 3.3-kb EcoRI fragment except for 180 bp of DNA in the second intron. The extra DNA consists of several (8-10) 20-bp tandem repeats flanked on each side by seven or eight copies of this same 20-bp repeat. Fisher X Sprague-Dawley hybrid rats, which contain both the EcoRI 3.5-kb form and the 3.3-kb form of the SVS IV gene, were crossed with each other. Analysis of the F1 generation demonstrated that the presence or absence of the 180-bp intronic insertion in the SVS IV gene defines an allelic difference. This report also presents the DNA sequence of the transcription unit and flanking regions of the SVS IV gene.

Designs for the 1990s (electric machines) (1989)

Customers are imposing increasingly arduous performance criteria on the electric machines which they order to meet all criteria simultaneously can often require highly optimised designs. In order to create these designs effectively, data from acceptance tests must be returned to the designers in a form which can be used to compare with the theoretical design. Furthermore, in order to carry out economic optimisation, manufacturing details must be made available to the designer.
Polysulfide Sealants for Automotive Stationary Glass (1970)

During the past 25 years, polysulfide sealants have become well known and widely used in the aircraft, marine, building, and more recently, the automotive industry. For automotive windshields, sealants must function on high speed production lines, maintain bonding power for 10 years or more, and meet new Federal Safety Specifications for glass retention. The most widely used automotive polysulfide sealant contains appropriate fillers, plasticizers, and bodying agents.
Detection of oncogene expression by fluorescent in situ hybridization in combination with immunofluorescent staining of cell surface markers. (1989)

To study oncogene expression in heterogeneous cell populations we developed and optimized a non-radioactive in situ hybridization technique using biotinylated single-stranded RNA probes and combined this technique with immunofluorescent staining of cell surface markers. As a model for our studies we used HL60 cells. In these cells we detected c-myc mRNA molecules by in situ hybridization following staining of the pan myeloid cell surface marker CD33, by a monoclonal antibody. Hybrids were detected by streptavidin-FITC and CD33 by a TRITC-conjugated antibody. Controls involved pretreatment with RNAase, hybridization with sense RNA probes and blocking with an excess of unlabeled antisense probes. The integrity of the RNA in the cell was shown by hybridization with the GAPDH antisense probe. Essential for successful double-labeling was the choice of a fixation procedure that was suitable for the in situ hybridization and mild enough not to destroy the cell surface marker staining. This fluorescent in situ hybridization in combination with cell surface marker staining will be useful for studying gene expression in phenotypically well-defined cell populations.
Palatine tonsillar metastasis from carcinoma of the colon (1994)

Metastatic carcinoma of the palatine tonsil is rare, with only 92 cases reported in the world literature. We report a case of tonsillar metastasis from the colon. This is an unusual case not only because it is the first case report of tonsillar metastasis from this site but also because the tonsillar secondary is the first sign of the primary disease.
