Supporting and Evaluating the Performances of Cooperative Networking Schemes on the NCTUns Network Simulator

Exploiting the broadcast nature of wireless networks, the cooperative networking / communication scheme becomes a new paradigm in wireless communication. Some of these designs exploit multi data rate feature in 802.11a/b/g standard to achieve better performance. In this thesis, we compare two cooperative networking designs and their performances. One of them exploits multi data rate feature, while the other does not. We concentrate on simulation research method and use NCTUns network simulator to evaluate the performances of these two designs. Advantages and disadvantages of these designs are also discussed.
Periodic Gossiping

Gossiping is a well-studied distributed algorithm whose purpose is to enable the members of a group of autonomous agents to asymptotically determine in a decentralized manner, the average of their initial scalar-valued gossip variables. T -periodic gossiping is a gossiping protocol which stipulates that each agent must gossip with each of its neighbors exactly once every T time unit. Under suitable connectivity assumptions of a graph characterizing all allowable gossip pairs, a T -periodic gossip sequence will converge at a rate determined by the magnitude of the second largest eigenvalue of the stochastic matrix determined by the sequence of gossips which occurs over a period. It has been shown in the prior work that if the underlying graph of allowable gossips is a tree, this eigenvalue is the same for all possible T -periodic gossip sequences. The aim of this paper is to develop several properties for stochastic matrices induced by the sequence of gossips occurring over a T period and reprove the result using these properties in a different and simpler argument.
Polarity Classification of Tourism Reviews in Spanish Clasificación de polaridad de revisiones de turismo en español

This article describes a polarity classifier for Spanish tourism reviews. We created a new data-set comprised by reviews of tourism resources (accommodations, restaurants, and activities) from the Basque Country in Spanish, by crawling the TripAdvisor review website. We adopt a supervised approach, and analyze various feature sets: an unigram model and various models that rely on the lexical information provided by a polarity lexicon, adapted to the tourism domain. The lexicon-based system achieves 83% accuracy for a 3-category classification task, and a 57% accuracy for a 5-category classification. Although the improvement over the unigram model is not significant it uses the half number of features which is more efficient. On top of that, evaluation is carried out for tourism resources sub-domains, including accommodation, restaurants and activities.
Asymptotic Gaussian Fluctuations of Spectral Clustering Eigenvectors

In this article, we analyze the asymptotic distribution of the eigenvectors used in spectral clustering of random graphs and in kernel spectral clustering of high dimensional Gaussian random vectors. For dense random graphs drawn from the Stochastic Block Model (SBM), we prove that the isolated dominant eigenvectors of the modularity matrix behave asymptotically like Gaussian random vectors with independent components. As opposed to previous works on SBM eigenvectors, we deal with a more challenging and practically meaningful growth rate of the edge probabilities. Similarly for kernel clustering of a two-class Gaussian mixture we prove the asymptotic Gaussianity of the finite-dimensional marginals of the single isolated eigenvector. We present two practical applications of our results: predicting the classification accuracy of clustering algorithms, and speeding up the convergence of the final Expectation Maximization (EM) clustering using an improved initialization.
The relationship between pancreatic cancer and type 2 diabetes: cause and consequence

: Pancreatic cancer (PC) is a devastating and lethal malignant disease and it is well known that there is a complex bidirectional relationship between PC and type 2 diabetes mellitus (T2DM). In order to more deeply summarize the relationship between them, this article sum-marizes the epidemiological data on the relationship between PC and T2DM in the past 5 years, and further explains the mechanism of interaction between them. Meanwhile, it also summed up the effects of drug therapy for T2DM on PC and the impact of T2DM on surgical resection of PC. Epidemiological studies clearly indicate that the risk of PC is increased in patients with T2DM. But increasing epidemiological data points out that PC also acts as a cause of T2DM and new-onset T2DM is sign and consequence of PC. Insulin resistance, hyperinsulinemia, hyperglycemia, and chronic in ﬂ ammation are the mechanisms of T2DM-Associated PC. Metformin decreases the risk of PC, while insulin therapy increases the risk of PC. Besides, studies have shown that T2DM decreases the survival in patients with PC resection.

Neural Network Based eNd-to-eNd learNiNg HierarcHy-aware semaNtic Parser for russiaN laNguage

We present neural network semantic parser for Russian language, that utilizes new copying mechanism, intermediate layers supervision and explicit handling of hierarchical nature of the output by means of having RNN blocks operating on different timeframes. Due to the lack of standard Russian dataset for validating semantic parsers, we develop our own small dataset in the domain of logistics and task management and demonstrate that our model can obtains good results on this dataset, despite it very limited size.
OP-NDTJ190036 1..7

Background. Risk of encapsulating peritoneal sclerosis (EPS) is strongly associated with the duration of peritoneal dialysis (PD), such that patients who have been on PD for some time may consider elective transfer to haemodialysis to mitigate the risk of EPS. There is a need to determine this risk to better inform clinical decision making, but previous studies have not allowed for the competing risk of death. Methods. This study included new adult PD patients in Australia and New Zealand (ANZ; 1990–2010) or Scotland (2000–08) followed until 2012. Age, time on PD, primary renal disease, gender, data set and diabetic status were evaluated as predictors at the start of PD, then at 3 and 5 years after starting PD using flexible parametric competing risks models. Results. In 17 396 patients (16 162 ANZ, 1234 Scotland), EPS was observed in 99 (0.57%) patients, less frequently in ANZ patients (n1⁄4 65; 0.4%) than in Scottish patients (n1⁄4 34; 2.8%). The estimated risk of EPS was much lower when the competing risk of death was taken into account (1 Kaplan–Meier1⁄4 0.0126, cumulative incidence function1⁄4 0.0054). Strong predictors of EPS included age, primary renal disease and time on PD. The risk of EPS was reasonably discriminated at the start of PD (Cstatistic 1⁄4 0.74–0.79) and this improved at 3 and 5 years after starting PD (C-statistic1⁄4 0.81–0.92). Conclusions. EPS risk estimates are lower when calculated using competing risk of death analyses. A patient’s estimated risk of EPS is country-specific and can be predicted using age, primary renal disease and duration of PD.
SLOW DYNAMICS IN TURBULENT VON KÁRMÁN HELIUM FLOWS

Abstract The presence of slow dynamics is a recurrent feature of many turbulent flows. This behaviour can be created by instabilities of the mean flow or by other mechanisms. In this work we analyze the behavior of a highly turbulent Helium flow (maximum Reynolds number Re = 10, with a Reynolds based on the Taylor microscale Reλ = 2000). We have performed velocity measurements using home-made Pitot tubes. The analysis of the data series reveals that below the injection frequencies there are different dynamical regimes with time scales two orders of magnitude below the injection scale.
Phase Transition and Elasticity of Gallium Arsenide under Pressure

Geometry optimization calculations were performed for some structural, elastic and mechanical properties of gallium arsenide (GaAs) under pressures up to 25 GPa. In contrast to previous works, a recent Stillinger-Weber type potential was used for the first time to elaborate the pressure dependence aspects of GaAs. B3→B1 phase transition pressure was determined as 17 GPa. Pressure dependence of density, typical cubic elastic constants, bulk, shear, and Young moduli, Poisson ratio, elastic velocities, anisotropy parameter, Kleinman parameter, elastic anisotropy degree, and stability conditions of GaAs were also evaluated. Overall, our results are satisfactory and can be helpful for future investigations of GaAs under pressure.
Overexpression of miRNA-23b-3p increased oxidative stress (as indicated by the levels of glutathione peroxidase, glutathione, superoxide dismutase and malondialdehyde) and apoptosis in neurocytes following high-glucose treatment. The overexpression of miRNA-23b-3p also suppressed SIRT1 and Nrf2 expr

In the present study the exact roles and mechanisms underlying the effect of miRNA-23b-3p on the cognitive impairment of diabetic rats were investigated. The in vivo model of diabetes was established in Wistar rats via a single injection of streptozotocin (STZ). Cognitive function was evaluated using a Morris water maze test. Oxidative stress was measured using ELISA kits, and the protein expression levels of B-cell lymphoma 2-associated X protein, silent information regulator 1 (SIRT1), nuclear factor erythroid 2-related factor 2 (Nrf2) and GAPDH were measured by western blot analysis. Micro (mi)RNA-23b-3p mimics were employed to increase miRNA-23b-3p expression in the in vitro model. Overexpression of miRNA-23b-3p increased oxidative stress (as indicated by the levels of glutathione peroxidase, glutathione, superoxide dismutase and malondialdehyde) and apoptosis in neurocytes following high-glucose treatment. The overexpression of miRNA-23b-3p also suppressed SIRT1 and Nrf2 expression in neurocytes following high-glucose treatment; it also promoted the SIRT1-induced inhibition of apoptosis and oxidative stress. The promotion of SIRT1 also decreased the effect of miRNA-23b-3p on cognitive impairment in diabetic rats. In conclusion, miRNA-23b-3p prevents the cognitive impairment of diabetic rats via anti-oxidative stress effects and the Sirt1/Nrf2 signaling pathway.
The role of IKKβ in interferon-γ-dependent signaling.

By David Shultz Activation of NFκB requires the inhibitor of κB (IκB) kinase (IKK) complex, which comprises two functional kinases, IKKα and IKKβ, and the scaffolding protein IKKγ. We previously identified several interferon (IFN)-γ-stimulated genes (ISGs) that are not induced in mouse embryonic fibroblast cells (MEFs) doubly -null for the expression of IKKα and IKKβ, and we show here that IFN-γ-induced transcription of IKK-dependent ISGs requires IKKβ but not IKKα. Through microarray studies, we identified IKKβdependent ISGs in both MEFs and RAW 264.7 macrophages. Many have both κB and ISRE elements, the latter of which bind IRF proteins, in their promoters. Although the IFN-γ-induced expression of the IKKβ-dependent gene ip-10 is sensitive to the superrepressor of NFκB and requires the p65 subunit of NFκB, IFN-γ does not activate NFκB. Thus, a distinct subset of IRF-activated IFN-γ-dependent genes requires some components of a normal NFκB activation pathway but not actual activation of NFκB in response to IFN-γ. IFN-γ activates IRF1 to bind the ISRE of ip-10. In IKKβ-null cells, IRF1 activation and binding to DNA are slightly weaker and the ability of IRF1 to transactivate a synthetic promoter composed of tandem copies of the ip-10 ISRE element is impaired. IFN-γ and IL-1β strongly synergize to induce ip-10. However, except at 1 h,
COMPARISON BETWEEN EFFICACY OF A SINGLE DOSE OF TINIDAZOLE WITH A 7-DAY STANDARD DOSE COURSE OF METRONIDAZOLE IN GIARDIASIS

Objective: Giardia intestinalis is the most common intestinal protozoan in the under developed countries. Treatment of infection has some difficulties by metronidazole because of long course of therapy and various side effects. The objective of this study was to determine efficacy and side effects of tinidazole compared with metronidazole in the treatment of giardiasis in children. Patients and Methods: A randomized controlled clinical trial, 106 subjects (69 males, 37 females) with Giardia intestinalis infection admitted to out patients or private clinics in Hamdan, West of Iran, was treated with tinidazole or metronidazole. The study period was May 2002 to January 2003. Tinidazole 50 mg/kg single dose and metronidazole 15 mg/kg three times a day for seven days were given orally to children. Parasitological cure was documented when there was 3 times negative stool examination for giardiasis at 1-2 weeks after therapy. Results: Thirty-seven of 42 individuals (88.1%) treated with tinidazole and 43 of 64 children (67.2%) treated with metronidazole had parasitological cure. Cure rates between two groups were significant statistically (P<0.01). No major side effect were observed except two cases in metronidazole group who had mild headache and abdominal pain for two days and some had metallic taste. Three cases in tinidazole group had nausea, dizziness and headache. Conclusion: Tinidazole was more effective than metronidazole, produced fewer and mild side effects and is recommended as drug of choice in single dose therapy for giardiasis. Because of single dose administration, short course of therapy and good compliance of patients, this preparation is preferred to metronidazole in the treatment of giardiasis.
MULTIMODAL COGNITIVE PROCESSING USING ARTIFICIAL ENDOCRINE SYSTEM FOR DEVELOPMENT OF AFFECTIVE VIRTUAL AGENTS

Abstract. In this paper a comprehensive architecture for emotional and aﬀective process in a virtual agent is presented . By fusing video, audio and text emotion of the users as aﬀective sources to the system, the virtual agent can appraise the mood of clients. To emulate the inﬂuence of the human hormones in the virtual agent, the proposed system employs Artiﬁcial Endocrine System (AES) in the aspects of moods and biological needs, by controlling the concentration level of the inﬂuential hormones. The agent aﬀective processor engages AES, personality and mood modules to manage the internal state. Intelligent virtual agent would interact with clients according to its aﬀective state circumstances. The proposed system presents a complete platform to capture emotional channels through the network to analyze and process them in an aﬀective engine in order to determine the emotional quality of the response.
Expenditure on prevention and care by disease in France

in 2002, France spent 10,5 billion Euros on prevention, i.e. 6.4% of current health expenditure, half of this on preventing disease or undesirable states, one quarter on disease screening and the remaining quarter on intervention in risk factors or early stage disease. Expenditure on prevention related to the Consumption of care and medical goods was 54.7 billion Euros. Consumption of care and medical goods excluding prevention has been allocated by disease. thus, expenditure on cardiovascular disease is the highest (12.6%), greater than mental illness and musculoskeletal disease (10.6% and 9% respectively).
Torsional Body Flexibility Effect on Stability in Trot and Pace based on a Simple Model

Quadrupeds use various gaits, depending on their locomotion speed [1]. At the middle speed range, they selectively use two gaits: trot and pace. In trot, quadrupeds synchronize their diagonal legs. On the other hand, in pace, they use ipsilateral pairs of legs [2, 3]. Most quadrupeds generally use trot gait, and a few quadrupeds inherently use pace gait [1–4]. However, the reason remains unclear. It is well known that body flexibility of quadrupeds highly affects on their gaits [5, 6]. In this research, the authors assumed that torsional flexibility of torso plays an important role in selections of trot or pace in animals. To investigate effects of torsional flexibility from the viewpoint of dynamics, the authors constructed a simple model with a torsional spring and derived periodic solutions analytically corresponding to trot and pace gait. Stability of periodic solutions was evaluated with eigenvalue analysis of linearized Poincaré maps.
Mechanisms of Antimicrobial Resistance

Acinetobacter baumannii is a significant pathogen in healthcare settings (specifically prominent in healthcareand ventilator-associated pneumonia) due primarily to its virulence and resistance to a wide variety of antimicrobial drug classes, including carbapenems (CRAB). Existing therapies (notably polymyxins, minocycline, tigecycline, amikacin, and sulbactam) often result in suboptimal tissue concentrations, high rates of toxicity, and increasing rates of resistance. Although utilizing combinations of antibiotics (specifically those containing colistin) have been employed, results have been mixed, and control trials are lacking. Eravacycline is a novel tetracycline with an improved pharmacokinetic profile and more potent activity against A. baumannii relative to tigecycline. Cefiderocol has a unique mechanism of action that has performed well in vitro against multidrugresistant (MDR) and CRAB isolates. Limited clinical data exists with each of these agents. Other novel antimicrobials are still in early phase clinical trials (ETX2514/sulbactam, TP-271, TP-6076, VNRX5133/cefepime, cefepime/zidebactam, AIC-499, GSK3342830, and SPR741) while further research is underway for non-antibiotic approaches, specifically monoclonal antibodies and bacteriophage therapies.

Fibroepithelial polyp excision with laser and scalpel: A comparative evaluation

Fibro epithelial polyps [FEP] are small round knob like outgrowths that can form anywhere on mucosa but are most common on tongue, lips and cheek along the occlusal line. They have a fibrous core covered by normal epithelium and are smoothmargined, and cylindrical, sessile. They are usually solitary, and reports of multiple, bilateral polyps are extremely rare. These polyps clinically appear as firm, pink, painless, sessile or pedunculated, polypoid swelling with varying size which range in a few millimetres (Lee. 1968).
Combined Effect of Lentinan and Cisplatin on Cytokines IL-6, TNF-α, and TGF-β in Tumor Therapy

Lentinan is a biologically active ingredient isolated from the fruiting body of Lentinula edodes (shiitake) and has antitumor properties. Cytokines, at the same time, are a key factor in regulating immune responses in physiological and pathological states. Many cytokines have shown positive effect on different malignancies in clinical trials. Studies have shown that such cytokines as IL6, TNF-α, and TGF-β play a quite important role in the formation of tumor microenvironment. In this study, we investigated the antitumor effect of combined medication of lentinan and cisplatin, another antitumor drug, and its impact on cytokines IL-6, TNF-α, and TGF-β in the treatment of tumor. The results showed that lentinan enhanced the cytotoxic effect of cisplatin on tumor cells. Furthermore, it was proved that the combined treatment of lentinan and cisplatin enhanced the inhibitory effect of cisplatin on the expression of IL-6, TNF- α, TGF-β and tumor growth in mice bearing human ovarian cancer xenograft, human prostate tumor xenograft, and human non-small cell lung cancer xenograft.
Performance Analysis of PCA & ANN for Recognize the IRIS & Fingerprint traits using SVM

The Biometric system is of one the essential pattern recognition system that are used for identifying individuals using different biometric traits. The authentication system design on only one biometric modality may not satisfy the requirement of demanding applications in term of properties such as accuracy, sensitivity & precision. In this paper, we used minutiae& gabour wavelet for the feature extraction of fingerprint & IRIS respectively. After extracting the feature we used ANN & PCA for classification of traits. After that we combine both the images which comes after the applying the ANN & PCA. On those resulting images we apply SVM for developing authentication system which uses the IRIS and Fingerprint of a person for recognizing a person. It is observed that developed algorithm that has best performance parameters as compared existing algorithms.
High Performance Polymers

The tensile properties of sulfonated polyoxadiazoles were studied as a function of molecular weight and sulfonation level. All sulfonated polyoxadiazoles synthesized through a polycondensation reaction of the hydrazine sulphate salt and a dicarboxylic acid in poly(phosphoric acid) exhibit rigid-ductile behavior with high Young’s modulus (3–4 GPa) and with larger elongations at break (up to 120%). Sulfonated polyoxadiazoles with maximum reproducible tensile strength (190 6.9 MPa) could be synthesized in the frame of time of 4–5 h.
