Intelligent learning techniques applied to quality level in voice over IP communications

—This paper presents a method for determining the quality of a Voice over IP communication using machine learning techniques. The solution proposed uses historical values of network parameters and communication quality in order to train the different learning algorithms. After that, these algorithms are able to ﬁnd the quality of the Voice over IP communication based on network parameters of a speciﬁc period of time. Intelligent and other machine learning algorithms take as input a baseline ﬁle that contains some values of network parameters and voice coding, associating an index quality for each scenario according to ITU-T Recommendation G.107. The tests were performed in an emulated network environment, totally isolated and controlled with real trafﬁc of voice and realistic IP network parameters. The quality ratings obtained for the learning algorithms in all the scenarios were corroborated with the results of the algorithm of ITU-T Recommendation P.862. The results show the reliability of the four learning algorithms used on the tests: Decision Trees (J.48), Neural Networks (Multilayer Perceptron), Sequential Minimal Optimization (SMO) and Bayesian Networks (Naive). The highest value of reliability for determining the quality of the Voice over IP communications was 0.98 with the use of the Decision Trees Algorithm. These results demonstrate the validity of the method proposed.
The applications of timed artificial insemination and timed embryo transfer in reproductive management of dairy cattle

Fertility of dairy cattle is generally decreasing. Overall estrus detection efficiency in lactating dairy cattle is low, as expression of estrus is often compromised. Consequently, undetected estrus, low AI-submission rates, and long inter-breeding intervals are the main contributors to poor reproductive efficiency. Although failure to become pregnant is the most common reason for culling dairy cattle, pregnancy rates could be improved by increasing the AI-submission rate through increased estrus detection efficiency, timed insemination (Timed-AI), or timed embryo transfer (Timed-ET). In these protocols, ovarian follicular development and luteolysis are controlled, culminating in synchronous ovulation in most cows. There are several modifications to improve pregnancy rates in Timed-AI protocols, e.g. presynchronization with 2 doses of PGF2a 14 d apart, and starting the Ovsynch protocol 12 d after the 2nd PGF2a. Timed-AI programs ensure a timely first breeding; this should be followed with early pregnancy diagnosis to identify nonpregnant cows, and prompt re-insemination. However, in a recent field study involving 23 dairy herds, the mean interval between 1st and 2nd breeding was 42 d; only 28% of the cows were rebred within 24 d after 1st breeding. Fortunately, there are several resynchronization protocols to reduce inter-breeding intervals. Anestrus cows, or those with cystic ovarian follicles, have a good chance of conceiving when subjected to synchronization of ovulation and Timed-AI. Furthermore, Timed-ET is a practical and viable option for synchronizing and selecting recipient cattle for embryo transfers. In summary, systematic and judicious use of Timed-AI and Timed-ET protocols can greatly enhance reproductive performance, and improve herd productivity.
Phylogeny of the Emballonurini (Emballonuridae) with descriptions of a new genus and species from Madagascar

Abstract Molecular phylogenetic studies suggest that the genus Emballonura, a member of the Old World tribe Emballonurini (Family Emballonuridae), is paraphyletic. This genus has a broad distribution across islands in the Indo-Pacific, southern Asia, and Madagascar. The paraphyly is the result of the genus Coleura, known from sub-Saharan Africa, portions of the Arabian Peninsula, Madagascar, and the Seychelles, being embedded between the Malagasy and Asian/Indo-Pacific clades of Emballonura, and the latter clade has priority for the use of the name. To resolve this situation, we propose a new genus for the Malagasy Emballonura clade. Furthermore, with greater molecular sampling of Coleura across portions of its range in association with morphological and bioacoustical characters, we are able to resolve aspects of the phylogenetic history and species limits of this genus. Coleura contains two well supported clades, including C. afra from mainland Tanzania and the offshore island of Pemba and a sister clade composed of C. cf. afra from Madagascar and C. seychellensis from the Seychelles. The average genetic distance between animals from Madagascar and the Seychelles is 6%, whereas Pemba/Tanzania and Madagascar is 10%. Because of the paraphyletic relationship of populations of C. afra with respect to C. seychellensis, we describe a new species of Coleura from Madagascar. Résumé Le genre Emballonura appartient à la tribu des Emballonurini (famille Emballonuridae), propre à l'Ancien Monde, et couvre une vaste aire de distribution comprenant des îles de la région Indo-Pacifique, l'Asie du Sud et Madagascar. Les études moléculaires montrent que ce genre est paraphylétique en raison de la position du genre Coleura qui vient s'insérer parmi les espèces d'Emballonura, entre les clades malgache et asiatique/indo-pacifique de ce dernier. Le clade asiatique/indo-pacifique d'Emballonura a la priorité nomenclaturale pour porter ce nom. Pour résoudre cette paraphylie, nous proposons de créer un nouveau genre pour les espèces d'Emballonura de Madagascar. Grâce à un échantillonnage moléculaire accru du genre Coleura, notamment avec l'inclusion de séquences de Tanzanie, des Seychelles et de Madagascar, ainsi que par l'utilisation de caractères morphologiques et bioacoustiques, nous décrivons les relations phylogénétiques et précisons la limite entre les espèces du genre Coleura. Ce dernier se subdivise en deux clades bien soutenus, l'un comprenant C. afra du continent et de l'île de Pemba, et l'autre C. cf. afra de Madagascar et C. seychellensis des Seychelles. La distance génétique ML entre les individus de Madagascar et des Seychelles est de 6%, alors que ceux de Pemba et Tanzanie diffèrent des malgaches de 9.6-10.4%. La Coleura de Madagascar est par conséquent décrite ici en tant qu'espèce nouvelle.

A simple and rapid differentiation method for combating therapeutically challenging planktonic and biofilm-producing Staphylococcus aureus

The aim of the current study is to establish a simple and fast method that can be easily applied in hospitals for the differentiation of biofilm and planktonic Staphylococcus aureusstrains. To achieve the objective, two reference strains, methicillin resistant S. aureus(MRSA) and methicillin sensitive S. aureus (MSSA) were examined using three types of methods; adhesion capacity of bacteria on polystyrene surfaces was verified using the quantification method followed by scanning electron microscope (SEM) in order to confirm the production of biofilm. In addition, to make a meaningful comparison of biofilm cells in stationary phase with a planktonic phase, the minimum inhibitory concentration (MIC) method was used. The results from this study demonstrated that the cells of the biofilm and planktonic cells can be differentiated by the simple MIC method. This study led to the development and improvement of methods for differentiation and detection of biofilm production of S. aureus. Key words: Biofilm, methicillin sensitive Staphylococcus aureus and methicillin resistantS. aureus, microtiter plate, scanning electron microscope, minimum inhibitory concentration, vancomycin.

Evaluation of techniques for C and ASG banding of the mitotic chromosomes of Anastrepha species (Diptera, Tephritidae)

Methods previously described by Canovai et al. (Caryologia 47: 241-247, 1994) which produced C and ASG bands in mitotic chromosomes of Ceratitis capitata were applied to the chromosomes of several Anastrepha species. Metaphase plate yield was substantially increased by use of imaginal disks together with cerebral ganglia. The C-bands were quite prominent allowing the resolution of tiny blocks of heterochromatin. The ASG method produced G-like banded chromosomes, which permitted recognition of each individual chromosome. These simple techniques do not require special equipment and may be valuable for karyotype variability studies in fruit flies and other Diptera
Converness: Ontology‐driven conversational awareness and context understanding in multimodal dialogue systems

Dialogue‐based systems often consist of several components, such as communication analysis, dialogue management, domain reasoning, and language generation. In this paper, we present Converness, an ontology‐driven, rule‐based framework to facilitate domain reasoning for conversational awareness in multimodal dialogue‐based agents. Converness uses Web Ontology Language 2 (OWL 2) ontologies to capture and combine the conversational modalities of the domain, for example, deictic gestures and spoken utterances, fuelling conversational topic understanding, and interpretation using description logics and rules. At the same time, defeasible rules are used to couple domain and user‐centred knowledge to further assist the interaction with end users, facilitating advanced conflict resolution and personalised context disambiguation. We illustrate the capabilities of the framework through its integration into a multimodal dialogue‐based agent that serves as an intelligent interface between users (elderly, caregivers, and health experts) and an ambient assistive living platform in real home settings.
Involvement of microRNA-30 family in metastatic dissemination of breast cancer cells to bone

Bone metastasis is a common complication of advanced breast cancers and is clinically responsible of bone fractures, hypercalcemia and pain for which only palliative therapies are proposed. Breast tumor cells that preferentially invade bone express a set of deregulated genes that enhance bone tropism and facilitate bone marrow engraftment which may lead to the formation of overt osteolytic lesions. Molecular pathways underlining these steps are regulated through the tight control of genes expressed by cancer cells interacting with cells from the bone microenvironment. In this context, microRNAs act as regulators of gene expression and control multiple aspects of bone metastasis, including tumor cell escape from the primary site, dissemination, invasion of the bone marrow and secondary outgrowth. MicroRNA transcriptomic profiling of osteotropic breast cancer cell lines identified drastic down-regulation of the miR-30 family (miRs-30). In the clinic, low expression of miRs-30 in breast primary tumors is associated with poor distant metastasis-free survival and hormoneinsensitive status. In a model of human bone metastasis in vivo, the forced expression of miRs-30 in a breast cancer cell line that is highly and specifically metastatic to bone inhibited bone metastasis. We demonstrated that miRs-30 inhibit tumor cell invasiveness and stimulate osteoblastogenesis, in vitro, and reduces tumor burden and osteoclast activity, in vivo. Consistent with that, the expression of several genes that promote bone metastasis were inhibited by miRs- 30. Among these, expression of connective tissue growth factor (CTGF) was up-regulated in human bone metastasis. The early steps of bone metastasis were studied in a mouse model using spontaneously metastatic mouse breast cancer cell lines inoculated in the mammary gland. In this model, miRs-30 did not alter tumor growth or metastatic dissemination to bone. However, miRs-30 inhibited cell invasiveness and cancer stem cell-like phenotype of these metastatic cells. We conclude that miRs-30, by interfering negatively with bone metastasis, represent a potential therapy to repress gene targets that promote bone metastasis
Prevalence and antibiotic susceptibility pattern of multidrug resistant gram negative bacilli in lower respiratory tract Infections in a tertiary care hospital of Tripura

Introduction: Lower respiratory tract infections with multidrug resistant gram negative bacteria are hard to treat and cause high morbidity and mortality. This study gives an account of isolation of multidrug resistant bacterial pathogens causing Lower respiratory tract infections and their antibiogram, in this geographical area of North East India. Materials and Methods: A total of 500 samples were collected and processed following the standard protocol. Antibiotic susceptibility test were performed by disc diffusion method, from which multidrug resistant strains were detected as per the criteria. Results: Out of 190 Gram Negative Bacilli isolated, 76 (40%) strains were confirmed to be multidrug resistant. Klebsiella pneumoniae (45.61%) was the predominant multidrug resistant Gram Negative Bacilli isolated, followed by Pseudomonas aeruginosa (36.48%), Acinetobacter spp (33.33%) and Citrobacter spp (28.57%). The multidrug resistant strains exhibited considerable susceptibility to Amikacin (65.78%), Gentamicin (68.42%) and Levofloxacin (68.42%). The Carbapenems, Betalactams and Beta-lactamase inhibitor combinations exhibited significant resistance in the present study. Conclusion: Klebsiella pneumoniae and Pseudomonas aeruginosa can be stated as the major causative agents of LRTI in this region. The present data represents the effective antibiotic agents against the MDR pathogens causing LRTI to be Amikacin, Gentamicin and Levofloxacin. Since none of the MDR strains attained a significant level of sensitivity against the tested antibiotics, specific treatment in our centre need to be decided based upon the antibiotic sensitivity profile of the isolate.
Enhancement of oleandrin production in suspension cultures of Nerium oleander by combined optimization of medium composition and substrate feeding

Abstract Oleandrin has been identified as the most potent antitumor ingredient of the Mediterranean herb Nerium oleander L. A strategy for optimization of medium compositions and conditions was developed for enhanced oleandrin production in suspension cultures from leaf-origin explants of Nerium oleander. The cell suspension cultures were grown in various modifications of MS medium as a basal medium. The effects of different natural extracts, plant growth substances, carbon and nitrogen sources and phosphate on the growth and oleandrin accumulation were investigated as well as effect of light, pH, shaking speed and substrate feeding. The highest oleandrin yield was obtained when the nitrogen concentration was lowered to two-thirds and the phosphate concentration increased by two-thirds of that specified in the MS medium in the presence of 3% sucrose, coconut milk, indolebutyric acid and benzyladenine in concentrations of 1 and 2 mg l−1, respectively. Lower pH and faster shaking speed favored oleandrin accumulation. Chemical feeding of progesterone and cholesterol boosted the oleandrin concentration to higher levels reaching 8.23±0.05 mg g−1 dry weight. This was about 10-fold higher than that detected in field-grown plants using the same extraction and analytic conditions, and about 24-fold higher than that determined in control cultures with regular MS medium and without precursor feeding.
Model Predictive Direct Speed Control With Torque Oscillation Reduction for PMSM Drives

Servo drives require high dynamics and reliability on speed control. Conventional cascade linear controllers suffer from the proportional-integral parameters tuning work and low dynamic response, due to their cascaded structure. In this paper, an improved model predictive direct speed control is proposed with rapid speed tracking and very small speed offset. The new control scheme eliminates the cascaded structure by predicting the future speed in discrete steps. The optimal voltage vector to control the motor is then selected according to an evaluation criterion for speed and flux tracking. To reduce the system cost and improve the reliability, a load torque observer is adopted to estimate the actual load torque. Besides, to avoid torque oscillations and overshoots during rapid speed variation, a torque suppression factor is incorporated into the cost function. Furthermore, a myopic prediction correction method is developed to enhance both the dynamic and steady-state responses. Simulation and hardware-in-the-loop results are presented to validate the effectiveness of the proposed method.
Spatial colonization patterns and interaction of bacteria on inoculated sugar beet seed

Development and spatial distribution of microcolonies of Pseudomonas spp. and Bacillus subtilis GB03 inoculated singly and in combination on sugar beet (Beta vulgaris) seed were observed with a scanning electron microscope (SEM). SEM examination of seed directly after inoculation with Pseudomonas strain 33-2 or ML5 at population densities of approximately 10 4 cfu per seed revealed a random distribution of individual cells. By 24 h, when population densities had reached the stationary phase (approximately 10 6 cfu per seed), microcolonies had developed in a random pattern over the seed surface. However, even at these populations, only 10-40% of the seed surface was colonized. Most microcolonies developed as separate entities on the indented surface of cells of the perianth and the operculum
Influence of X-ray and/or CpG-DNA induced oxidative stress on adaptive response in human lymphocytes

Peripheral blood lymphocytes of apparently healthy donors were exposed to low-dose ionising radiation and/or human-genome CpG-DNA fragments accumulating in total extracellular DNA. Both factors administered separately appeared to induce transposition of the 1q12 loci of homologous chromosomes in lymphocytes from the pericentromeric region towards the centre of the nucleus; they were also shown to activate rRNA synthesis, to stimulate activation of caspase-3 activity and to increase amounts of the TLR9 and MyD88 mRNAs. However, upon simultaneous exposure to X-ray radiation and CpG-DNA, all the reactions mentioned above failed to develop in the cells. Practical aspects of the revealed phenomenon are discussed in this paper.
Relationship between settlement of southern rock lobster pueruli, Jasus edwardsii , and recruitment to the fishery in Tasmania, Australia

Puerulus catches on artificial collectors were measured monthly at four sites around Tasmania from 1991 to April 2000, with the aim of predicting future changes in recruitment to the fishery. Support for the potential of catch-rate prediction in Tasmania was provided at the two sites that have overlap of several years between indices of puerulus settlement and indices of the abundance of recruits to the fishery. At Bicheno, on the northeast coast, correlations between annual puerulus index and commercial catch rates were highly significant, with a lag of 5 years (P< 0.01). Similar interannual trends in puerulus index and estimates from a stock-assessment model of the biomass of recruits to the fishery provided additional support for a link with puerulus index. A 5-fold interannual variation in puerulus index detected at Bicheno, with a peak in 1995, was preceded by 3 years of relatively low puerulus catch. The peak in puerulus index appears to lead to an increase in the abundance of sublegal males in research sampling 3 years later. Correlation between annual measures of puerulus index and catch rate also appeared significant at King Island (P= 0.06) although data at this site had less contrast.
AN ULTRA FAST AGILE LOCAL OSCILLATOR FOR CUEUING CHANNELIZED RECEIVERS

An ultra fast frequency agile local oscillator with high spectral purity is presented. It can be used in a queuing channelized receiver to generate the required local oscillator frequency for each newly received pulse within the pulse duration. It can also be used as a local oscillator in pulse-to-pulse frequency agile radars with high pulse repetition frequencies. The time necessary to change the oscillator frequency is that of the output electronic switch. The phase noise and the frequency stability are those of the crystal oscillator. The spectral purity is guaranteed by the proper filter design.
APPLICATION NOTE Attune NxT Flow Cytometer Validated 10-color T cell panel using the Attune NxT Flow Cytometer

Introduction Multicolor immunofluorescence panels are widely used in flow cytometry and are often difficult and time-consuming to develop. The Optimized Multicolor Immunofluorescence Panel (OMIP) publications were established to help the researcher by providing a thoroughly tested and validated set of antibodies and reagents that can be used together for multiparameter characterization or evaluation of a specific cell state or response [1]. Each OMIP publication is meant to help alleviate the burden of panel development and optimization by providing the technical details and experimental conditions used to optimize each panel [2]. By definition, an OMIP publication includes all of the necessary information required for the execution of the panel of interest. The OMIP publication contains an overview of the purpose of the panel, a listing of antibody clones and fluorophore combinations, information on sample type, and similarities to any existing OMIPs, as well as a representative figure showing experimental results including the gating strategy. In this application note, we take advantage of the OMIP-009 publication [3], which is optimized for characterizing the immunological response of human T cells, applying it to the 4-laser, 16-parameter configuration of the InvitrogenTM AttuneTM NxT Flow Cytometer with Autosampler. Additionally, we discuss the importance of antibody titration and optimizing antibody concentration in panel testing. Furthermore, we review the importance of fluorescence minus one (FMO) controls.
ON THE NUMERICAL QUENCHING TIME AT BLOW-UP

This paper deals with the study of the numerical approximation for the following boundary value  vt = vxx + ε(1− v)−β , (x, t) ∈ Ω× (0, T ), v(±1, t) = 0, t > 0, v(x, 0) = v0(x) > 0, x ∈ Ω, where Ω is a bounded domain in R , β > 0, and ε > 0. By a transformation, we obtain some conditions under which the solution vt of the above problem blows up in finite time and estimate its semidiscrete blowup time. We also establish the convergence of the semidiscrete blow-up time to the real one when the mesh size goes to zero. Finally, we give some numerical experiments to illustrate our analysis.
