Fairness issues in a chain of IEEE 802 . 11 emitters

We study a simple general scenario of ad hoc networks based on IEEE 802.11 wireless communications, consisting in a chain of emitters, each of them being in the carrier sense area of its neighbors. Each emitter always attempts to send some data frames to one receiver in its transmission area, forming a pair emitter-receiver. This scenario encompass the three pairs fairness problem introduced in [1], and allows to study some fairness issues of the IEEE 802.11 medium access mechanism. We show by simulation that interesting phenomena appear, depending on the number n of pairs in the chain and of its parity. We also point out a notable asymptotic behavior. We introduce a powerful modeling, by simply considering the probability for a transmitter to send data while its neighbors are waiting. This model leads to a nonlinear system of equations, which matches very well the simulations, and which allows to study both small and very large chains. We then analyze the fairness issue in the chain regarding some parameters, as well as the asymptotic behavior. By studying very long chains, we notice very good asymptotic fairness of the IEEE 802.11 medium sharing mechanism.
A Pairing-Free Identity Based Tripartite Signcryption Scheme

The certificate-based cryptosystems is traditional way in providing the system parameters. Identity-based cryptography is more efficient than certificate-based cryptosystems. Each user in identity-based cryptography uses any arbitrary string that uniquely identifies him as his public key. This paper proposes a new identity-based tripartite signcryption scheme based on the elliptic curve discrete logarithm problem. The proposed id-based tripartite signcryption scheme does not use the bilinear pairings in both the Signcryption and unsigncryption phases. The proposed scheme used to reduce the communication over head when three entities wants to communicate securely as in authentication protocol in GSM and in ecommerce. The proposed scheme satisfies various desirable security properties. Also, the performance of the proposed scheme is tested.
NEW FLOW CYTOMETRIC METHODS FOR EVALUATING BULL SEMEN 1

Bull fertility and semen quality are of paramount importance to the cattle industry. Fluorescent biomarkers measured by flow cytometry can aid in the detection of sub-fertile bulls as they can identify abnormal spermatozoa that may not be properly identified as inferior with standard methods of subjective semen analysis. This paper introduces the basics of flow cytometry, discusses fluorescent biomarkers of sperm quality in current use, and summarizes results from sperm proteomic studies in the bull.
Hauora: Māori Standards of Health IV

This right is derived from different sources. Firstly, from our indigenous rights embodied in the United Nations Declaration on the Rights of Indigenous Peoples (United Nations 2007) and reinforced by the Treaty of Waitangi (CERD 2007). The primary right of indigenous peoples is to self-determination, which includes to name ourselves as tangata whenua and be recognised as such. As tangata whenua, our duty includes ensuring the wellbeing of all people in our territories, Màori and tauiwi. This necessitates Màori monitoring health, including any disparities in health outcomes between Màori and non-Màori.
General Kalman Filter & Speech Enhancement for Speaker Identification

Presence of noise increases the dimension of the information. A noise suppression algorithm is developed with an idea of combining the General Kalman Filter and Estimate Maximization (EM) frame work.This combination is helpful and effective in identifying noise characteristics of an acoustic environment. Recursion between Estimate step and Maximization step enabled the algorithm to deal any model of noise. The same Speech enhancement procedure in applied in the pre-processing stage of a conventional Speaker identification method. Due to the non-stationary nature of noise and speech adaptive algorithms are required. Algorithm is first applied for Speech enhancement problem and then extended to using it in the pre-processing step of the Speaker identification. The present work is compared in terms of significant metrics with existing and popular algorithms and results show that the developed algorithm is dominant over them.

Plasmid transfer capacities of multi- resistant UPEC clinical isolates in biofilms

Uropathogenic Escherichia coli (UPEC) is the leading causative agent of Urinary tract infection (UTI). The emerging multidrugresistance of UPEC to antimicrobial agents (such as antibiotics or Chinese herbs) has been a serious public health problem and may result in the complication or failure of UTI therapy, yet with unknown underlying mechanisms. Our present study aims to explore the plasmid DNA-based gene transfer mechanism of the drug resistance UPEC strains. The pPICZαA plasmid containing the Zeocin resistance gene was applied as extraneous resistance plasmid to investigate the uptake ability of plasmid and the plasmid transfer frequency of a UPEC stain alone or co-culturing with DH5α bacteria during the formation of biofilm process. The results showed that the uptake efficiency and plasmid transfer frequency increased from 8 h to 24 h during the biofilms formation, and then slowed down after the formation of biofilms. What’s more, the plasmid transfer frequency was independent of the bacteria culture conditions. Our present study is of importance to the mechanisms illustration of multidrug resistance (like herbal medicine) in UPEC, and might provide a foundation for the research of resistance gene spreading reduction.
Electronic structure of the Ru(0001) surface

This paper deals with the electronic structure of ruthenium. Synchrotron radiation in the range from 15 to 45 eV and angle-resolved ultraviolet photoemission are used to map the energies of the electronic states. The Fermi surface of Ru is determined using angle-resolved ultraviolet photoemission spectroscopy. The experimental results are compared with calculated photoemission spectra obtained within the framework of the one-step model of photoemission.
The Kernel Bundle of a Holomorphic Fredholm Family

Let 𝒴 be a smooth connected manifold, Σ ⊂ ℂ an open set and (σ, y) → 𝒫 y (σ) a family of unbounded Fredholm operators D ⊂ H 1 → H 2 of index 0 depending smoothly on (y, σ) ∈ 𝒴 × Σ and holomorphically on σ. We show how to associate to 𝒫, under mild hypotheses, a smooth vector bundle 𝒦 → 𝒴 whose fiber over a given y ∈ 𝒴 consists of classes, modulo holomorphic elements, of meromorphic elements φ with 𝒫 y φ holomorphic. As applications we give two examples relevant in the general theory of boundary value problems for elliptic wedge operators.
Infectious Complications in Peritoneal Dialysis: The Spectrum of Causative Organisms and Recommended Treatment Options

Peritoneal dialysis (PD) has become a real alternative to hemodialysis (HD) in recent decades, with comparable survival rates, lower costs, and improved patient quality of life. Nevertheless, PD‐related infections, including peritonitis, exit‐site infections (ESI), and tunnel infections, are important complications, resulting in significant morbidity and a 3.5–10.0% risk of death. Patients with peritonitis usually present with cloudy PD‐ fluid and abdominal pain; however, PD‐associated peritonitis should always be included in differential diagnosis of PD patients with abdominal pain. The most common causative organisms for PD‐associated peritonitis are gram‐positive bacteria; however, gram‐negative species are clinically important, due to the antibiotic resist‐ ance. The selection of empiric antibiotics depends on the center‐specific distribution of microorganisms and antimicrobial susceptibility profiles. Typically, a first‐generation cephalosporin is used in combination with broad gram‐negative coverage (e.g., aminoglycoside, ceftazidime, or cefepime). High levels of methicillin‐resistant Staphylococcus epidermidis or Enterococcus spp. strains require the use of vancomycin in many centers. Furthermore, for patients without clinical improvement after 5 days, or with fungal peritonitis, catheter removal is indicated.

Effect of Broccoli on the Antioxidant Activity of Experimental Rats Ingested Thermally Oxidized Oil

The effect of broccoli powder, aqueous and methanolic extracts on antioxidant activity in rats fed on thermally oxidized oil was studied. Chemical analysis of broccoli was investigated. Five groups of rats were used; group (1) was used as a negative control, while rats of the other groups were fed thermally oxidized oil in diet. Group (2) was left as a positive control, while groups (3), (4) and (5) were administered broccoli powder, aqueous and methanolic extracts for 60 days. The obtained results revealed that broccoli contains carbohydrate, protein, fiber and ash, and also high amount of potassium, calcium, phosphorous, total phenol and flavonoids. Positive control group which consumed oxidizing frying oil in diet showed a significant decrease in body weight, Food efficiency ratio (FER) and food intake. Also, it showed a significant increase in serum cholesterol (CHO), triglycerides (TG), low density lipoprotein cholesterol (LDLc), very low density lipoprotein cholesterol (VLDLc) and CHO/ HDLc, malodialdehyde (MDA); and liver cholesterol and total lipid but a significant decrease in serum high density lipoprotein cholesterol (HDLc), superoxide dismutase (SOD), catalase, glutathione transferase (GST), and glutathione peroxidase (GPX); and liver triglyceride in comparing to negative control group. Broccoli powder, aqueous and methanolic extract rat groups showed that the values of liver cholesterol, total lipid and triglyceride appeared within values of negative control. However, they showed a significant decrease in liver parameters and serum MDA and significant increase in serum antioxidant enzymes activity comparing to positive control group This study concluded that broccoli have ability to increase antioxidant activity in rats ingested thermally oxidized oil. Broccoli methanolic extract give the most favorable results, therefore this study recommends to intake broccoli when consuming fried foods. (Amnah, M. A.Alsuhaibani.

Subjective Evaluation of Maxillofacial Landmarks with Different Resolutions of Cone Beam Computed Tomography

Introduction: There are some anatomical considerations that are important while selecting a dental treatment plan, such as measurement of height, width, quality, and density of the alveolar bone for placement of the implant, identification of the possible pathologies, and observation of the periodontal ligament around the impacted teeth to determine the presence or absence of ankylosing. With the advances in technology, the size of the voxels in cone beam computed tomography (CBCT) has reduced and the resolution of the images has increased. Since this increase in resolution also increases the radiation dose to the patient, we aimed to investigate the accuracy of detection of the anatomical landmarks in implantology with different CBCT resolutions and the possibility of minimizing patient radiation dose by decreasing the resolution.
Force Balancing of Robotic Mechanisms Based on Adjustment of Kinematic Parameters

Force balancing is a very important issue in mechanism design and has only recently been introduced to the design of robotic mechanisms. In this paper, a force balancing method called adjusting kinematic parameters (AKP) for robotic mechanisms or real-time controllable (RTC) mechanisms is proposed, as opposed to force balancing methods, e.g., the counterweights (CW) method. Both the working principle of the AKP method and the design equation with which to construct a force balanced mechanism are described in detail. A particular implementation of the AKP method for the RTC mechanisms where two pivots on a link are adjustable is presented. A comparison of the two methods, namely the AKP method and the CW method, is made for two RTC mechanisms with different mass distribution. The joint forces and torques are calculated for the trajectory tracking of the RTC mechanisms. The result shows that the AKP method is consistently better than the CW method in terms of the reduction of the joint forces and the torques in the servomotors, and the smoothing of the fluctuation of the joint force.
RAPID RISK ASSESSMENT Extensively drug-resistant ( XDR ) Neisseria gonorrhoeae in the United Kingdom and Australia 7 May 2018

The first three cases of infection with extensively drug-resistant (XDR) Neisseria gonorrhoeae displaying resistance to ceftriaxone (MIC = 0.5 mg/L) and high-level resistance to azithromycin (MIC >256 mg/L) at a global level were reported by the United Kingdom (one case) and Australia (two cases) in February and March 2018, respectively. The case from the UK and one case from Australia were travel-associated and both acquired gonorrhoea in South-East Asia. These strains are the first global reports of high-level azithromycin resistant N. gonorrhoeae which is also resistant to ceftriaxone as well as most other alternative antimicrobials. Consequently, they are resistant to the first line dual therapy for gonorrhoea (ceftriaxone intramuscularly and azithromycin orally) recommended by European, Australian, World Health Organisation and other guidelines. They highlight the increasing threat of multidrug(MDR) and extensively drug-resistant (XDR) gonorrhoea in the context of limited therapeutic alternatives, lack of vaccine and limited surveillance capacity in many regions globally.
Impact of the 2015 wildfires on Malaysian air quality and exposure: a comparative study of observed and modeled data

In September and October 2015, Equatorial Asia experienced the most intense biomass burning episodes over the past two decades. These events, mostly enhanced by the extremely dry weather associated with the occurrence of strong El Niño conditions, resulted in the transnational transport of hazardous pollutants from the originating sources in Indonesian Borneo and Sumatra to the highly populated Malaysian Peninsula. Quantifying the population exposure form this event is a major challenge, and only two model-based studies have been performed to date, with limited evaluation against measurements. This manuscript presents a new data set of 49 monitoring stations across Peninsular Malaysia and Malaysian Borneo active during the 2015 haze event, and performs the first comparative study of PM10 (particulate matter with diameter < 10 µm) and carbon monoxide (CO) against the output of a state-of-the-art regional model (WRF-Chem). WRF-Chem presents high skills in describing the spatio-temporal patterns of both PM10 and CO and thus was applied to estimate the impact of the 2015 wildfires on population exposure. This study showed that more than 60% of the population living in the highly populated region of the Greater Klang Valley was systematically exposed to unhealthy/hazardous air quality conditions associated with the increased pollutant concentrations from wildfires and that almost 40% of the Malaysian population was on average exposed to PM10 concentrations higher than 100 µg m−3 during September and October 2015.
Induction of the Formyl Peptide Receptor 2 in Microglia by IFN-γ and Synergy with CD40 Ligand12

Human formyl peptide receptor (FPR)-like 1 (FPRL1) and its mouse homologue mFPR2 are functional receptors for a variety of exogenous and host-derived chemotactic peptides, including amyloid β 1–42 (Aβ42), a pathogenic factor in Alzheimer’s disease. Because mFPR2 in microglial cells is regulated by proinflammatory stimulants including TLR agonists, in this study we investigated the capacity of IFN-γ and the CD40 ligand (CD40L) to affect the expression and function of mFPR2. We found that IFN-γ, when used alone, induced mFPR2 mRNA expression in a mouse microglial cell line and primary microglial cells in association with increased cell migration in response to mFPR2 agonists, including Aβ42. IFN-γ also increased the endocytosis of Aβ42 by microglial cells via mFPR2. The effect of IFN-γ on mFPR2 expression in microglial cells was dependent on activation of MAPK and IκB-α. IFN-γ additionally increased the expression of CD40 by microglial cells and soluble CD40L significantly promoted cell responses to IFN-γ during a 6-h incubation period by enhancing the activation of MAPK and IκB-α signaling pathways. We additionally found that the effect of IFN-γ and its synergy with CD40L on mFPR2 expression in microglia was mediated in part by TNF-α. Our results suggest that IFN-γ and CD40L, two host-derived factors with increased concentrations in inflammatory central nervous system diseases, may profoundly affect microglial cell responses in the pathogenic process in which mFPR2 agonist peptides are elevated.
ENVIRONMENT OF THE SUBMILLIMETER-BRIGHT MASSIVE STARBURST HFLS3 AT z ∼ 6.34

We describe the search for Lyman break galaxies (LBGs) near the submillimeter-bright starburst galaxy HFLS3 at z = 6.34 and a study on the environment of this massive galaxy during the end of reionization. We performed two independent selections of LBGs on images obtained with the Gran Telescopio Canarias (GTC) and the Hubble Space Telescope (HST) by combining nondetections in bands blueward of the Lyman break and color selection. A total of 10 objects fulfilling the LBG selection criteria at z > 5.5 ? > were selected over the 4.54 and 55.5 arcmin2 covered by our HST and GTC images, respectively. The photometric redshift, UV luminosity, and star formation rate of these sources were estimated with models of their spectral energy distribution. These z ∼ 6 ? > candidates have physical properties and number densities in agreement with previous results. The UV luminosity function at z ∼ 6 and a Voronoi tessellation analysis of this field show no strong evidence for an overdensity of relatively bright objects ( m F 105 W < ? > 25.9) associated with HFLS3. However, the overdensity parameter deduced from this field and the surface density of objects cannot exclude definitively the LBG overdensity hypothesis. Moreover, we identified three faint objects at less than 3″ from HFLS3 with color consistent with those expected for z ∼ 6 galaxies. Deeper data are needed to confirm their redshifts and to study their association with HFLS3 and the galaxy merger that may be responsible for the massive starburst.
Diffusion of New Technology in Indian Auto Component Industry: An Examination of the Determinants of Adoption

The contribution of new technologies to economic growth is harnessed only when new technologies are widely diffused in the economy. Diffusion results from a series of individual decisions to introduce the new technologies, decisions being the result of a comparison of the uncertain benefits and costs associated with adoption. An understanding of the factors affecting this choice is therefore an essential step forward in order to study the diffusion process of new technologies. The aim of this paper is to provide a comprehensive understanding of the possible set of factors determining adoption of new technologies such as Advanced Manufacturing Techniques (AMTs) in the Indian auto component industry. Building on both the early ‘epidemic' and the later ‘equilibrium' theories of adoption, our analysis is purported to provide an empirical exploration of determinants of adoption that takes into account the influence of structural, (i.e., firm-specific), and socio-economic factors on the process of adoption. Our results, though confirms most of the theoretical and empirical predictions about technology adoption, provides new evidence on the importance of external sources of knowledge and the crucial role of demand side on the adoption process.
