Modeling 802.11 AP Usage through Daily Keep-Alive Event Counts

Wireless and in particular 802.11 is one of the major technologies for accessing the Internet at home, in coffee shops or other public places, and in enterprises and university campuses. While most recent work on modeling wireless sites focuses on user mobility, this paper presents and compares a number of models for characterizing access point (AP) usage; moreover, rather than looking at throughput we focus on daily counts of keep-alive events that mobile devices generate every 15 minutes they are connected to the wireless network. Our models are trained and evaluated on data collected from a Porto hotspot of Eduroam, the European academic wireless network. The models we present are generative, in the sense they can be used to generate synthetic daily event counts for a single AP or a collection of APs. We provide standard cross validation comparison of models using the log-likelihood of the models on training and test data.

Adherence of <i>Streptococcus mutans</i> to implant materials

Abstract The adherence of Streptococcus mutans OMZ‐176 to six implant materials (polycrystal alumina, single‐crystal alumina, titanium alloy, cobalt‐chromium‐molybdenum alloy, hydroxyapatite, and heat‐curing polymethylmethacrylate resin) was studied in vitro . The change of free energy, which corresponds to the adherence process, was also evaluated for hydrophobic interaction. Adherence of S. mutans to poly‐crystal alumina was lower than adherence to other materials. The adherence of S. mutans to the test materials was highly correlated with the change of free energy, which suggests that hydrophobic interaction plays an important role in the adherence of S. mutans to the implant materials.

Characterization of a Horizontal Two-Phase Spray from an Effervescent Atomizer

An experimental study is presented to investigate the evolution of the droplets in the near field region of an effer­ vescent spray using Shadowgraphy, observing spherical and non­spherical droplets. Experiments were conduc­ ted with water and air, in a horizontal two­phase flow, with a 25.4 mm diameter feeding conduit. Water flow rates from 1.89 to 3.15 kg·s ­1 and air to liquid ratio from 1 % to 4 %, were selected to investigate their influence on the spray. Acquired images were employed to estimate the droplets size, shape and velocity. Measurements were done at different locations along the axial and radial directions of the spray. Results indicate the locations and flow rates at which non­spherical particles are more evident. This leads to con­ ditions at which particles are not fully atomized. Radial changes of Sauter Mean Diameter (SMD) were ob­ served. The momentum of the spray was measured at several locations with an impact probe. The spray atomizer investigated in this study is used in heavy oil upgrading. Thus, knowledge of the droplet behaviour in the spray provides data to enhance the design and operating conditions of the atomization process.

Abstract 397: HMOX1 Ameliorates Fatty Liver and Metabolic Syndrome by Reduction of Hepatic Heme and PGC1a

Introduction: Nonalcoholic fatty liver (NAFLD) occurs in a setting of high fat diets, insulin resistance, obesity and dyslipidemia. Individuals with NAFLD have an increased risk of developing metabolic syndrome. Heme oxygenase-1 (HMOX1), a major cytoprotective enzyme, attenuates oxidative stress and obesity and increases insulin sensitivity. The antioxidant effect of HMOX1 is due to an increase in ferritin, and bilirubin and a decrease in heme, a pro-oxidant. The aim of this study was to examine the role of increased hepatic HMOX activity in decreasing steatosis, adiposity and vascular dysfunction and to determine the mechanism underlying these metabolic changes in obese mice. Methods: Obese mice were administered cobalt protoporphyrin (CoPP) and HMOX activity inhibitor stannous mesoporphyrin (SnMP) for 6 weeks. Blood pressure, body weight and blood glucose levels were measured in all the groups. Glycogen content, hepatic fibrosis, heme levels, fatty acid synthase (FAS) and lipid droplet size in liver were also assessed. Results: CoPP administration increased hepatic HMOX1 protein levels and HMOX activity, decreased blood pressure, body weight, blood glucose levels, hepatic heme content (p&lt;0.05) as compared to obese mice. Our results also showed that HMOX1 induction causes a significant decrease in lipid steatosis ( lipid droplet size and FAS levels; p&lt;0.01) as compared to obese mice. Densitometry analysis showed increased expression of PPARα and Glut 1 along with decreased expression of PGC1α in hepatic tissue. These beneficial effects were reversed by administration of SnMP. Conclusion: This novel study demonstrates the role of hepatic HMOX1 in attenuating the fatty liver and metabolic homeostasis by decreasing PGC1α and heme content and enhancing glycogen levels. Pharmacological agents that increase HMOX1 levels or gene targeting of HMOX1 offer a promising therapeutic target for NAFLD and suggest the existence of a significant link between the heme-HMOX system and the extent and severity of heme-dependent fatty liver.

Formation Mechanism of Two Types of Polytype Transformation in off-axis 4H-SiC Boules

The morphology and distribution of polytypes are studied by confocal laser scanning microscopy (CLSM) and Micro-Raman spectroscopy. Based on the experimental results, two possible formation mechanisms of foreign polytypes are proposed. One phenomenon is that the polytype transition interface tilts toward the seed crystal plane, which is related to the step flow growth mechanism. By reducing the crystal growth rate at the starting point of the step, this foreign polytypes can be effectively avoided. Another phenomenon is that the polytype transition interface is parallel to the seed crystal plane, which usually occurs in the later growth stage. This is related to the increase of the temperature of the growth front, which is also confirmed by the theoretical simulation results obtained by commercial VR™-PVT SiC software.

Microfungi associated with a myrmecophyte Macaranga bancana

Microfungal populations associated with the domatia and food bodies of Macaranga bancana (Euphorbiaceae) and its obligate symbiotic ant Crematogaster borneensis were examined using culture-dependent methods. Forty-four fungal isolates were obtained and grouped into 15 operational taxonomic units (OTUs): 11 in Sordariomycetes and two each in Dothideomycetes and Eurotiomycetes. Hypocreales sp.3 (OTU3) was the commonest OTU isolated using the moist chamber method, followed by Paecilomyces sp. (OTU7), Chaetosphaeriaceae sp. (OTU10), Botryosphaeriaceae sp. (OTU12), and Aspergillus sp. (OTU15). Hypocreales sp.1 (OTU1) was the commonest OTU isolated by direct inoculation of the food bodies of M. bancana, darkened domatia materials, and ants and scale insects inside the domatia, followed by Hypocreales sp.3 (OTU3) and Chloridium sp. (OTU11). Molecular phylogenetic affinities of the 15 OTUs suggested that the closest relatives of three, nine, and 13 OTUs were known as insect-associated fungi, plant pathogens, and saprobic fungi, respectively. The possible role of these fungi is discussed.

Preparation, characterization, and luminescence of (SBA-15) immobilized pepsin

SBA-15 mesoporous silica was synthesized by hydrothermal method and its surface was methylated by treatment with methyltrimethoxysilane. Pepsin was immobilized on the obtained materials giving host-guest composite materials (SBA-15)-pepsin and (methylated SBA-15)-pepsin. The optimum conditions for preparation of these materials were established. Methylated SBA-15 (M-SBA-15) has improved immobilization efficiency of enzyme compared to initial SBA-15 silica. It was shown that with the gradual increase of NaCl solution ionic strength the immobilized amount of enzyme was reduced. Powder X-ray diffraction and Fourier transform infrared spectroscopy showed that the host frameworks in the prepared host-guest composite materials are intact and the ordered structure was retained. Scanning electron microscopic studies revealed fibrous morphologic characteristics of the SBA-15 and the immobilized pepsin composite materials. The average particle diameter of (SBA-15)-pepsin composite was 338 ± 10 and 343 ± 10 nm for (M-SBA-15)-pepsin. The low temperature N2 adsorption-desorption study at 77 K showed that the pore sizes and specific surface areas of the host-guest composite materials were smaller than those before the introduction of the enzyme, suggesting that the immobilized enzyme occupied a definite position in the host material pore channels. The UV-vis solid diffuse reflectance and luminescence studies showed that the enzyme was successfully immobilized on to the host material and that after the immobilization of enzyme on SBA-15 the conformation of pepsin macromolecule has not been changed.

The Efficient Scenario of Solving NAT Traversal in the IMS

IP 주소 공간의 부족 문제를 해결하기 위해 NAT(Network Address Translation) 기술을 활용할 수 있다. NAT의 주소 변환 테이블에 없는 바인딩과 관련된 패킷을 제거하는 필터링 특성 때문에 NAT Traversal 문제가 발생한다. 이러한 문제를 해결하기 위해 부가적인 장비를 활용한 여러 가지 방법들이 제시되었다. 최근의 네트워크 시장은 유선과 무선이 통합되는 형태로 발전하고 있으며, 이를 효과적으로 제어하기 위하여 IMS(IP Multimedia Subsystem)라는 유무선 통합 제어 망이 등장하였다. IMS에서 IBCF(Interconnection Border Control Function)와 IBGF(Interconnection Border Gateway Function)라는 부가적인 장비를 이용하여 NAT Traversal 문제를 해결하고 있다. 본 논문에서는 P-CSCF(Proxy-Call Session Control Function)를 활용하여 부가적인 장비를 사용하지 않고 NAT Traversal 문제를 해결하는 방안을 제안한다. We can use NAT(Network Address Translation) technology to solve the lack of IP address. The problem of NAT traversal is happened when the filtering characteristics of NAT remove the packet that has no binding in the address translation table of NAT. There were many kinds of way to solve these problems by using additional device. Lately, network market is changed into integrating wired and wireless network by the IMS(IP Multimedia Subsystem). The IMS integrates to control network of wired and wireless network, has emerged to control convergence network effectively. Lately, the additional devices like IBCF(Interconnection Border Control Function) and IBGF(Interconnection Border Gateway Function) are used to solve the NAT traversal problem in the IMS. In this paper, we propose the solution of NAT traversal using P-CSCF without any additional equipment in the IMS.

All rights of reproduction in any form reserved. The Bystander Effect in Radiation Oncogenesis: II. A Quantitative Model

There is strong evidence that biological response to ionizing radiation has a contribution from unirradiated ‘‘bystander’’ cells that respond to signals emitted by irradiated cells. We discuss here an approach incorporating a radiobiological by-stander response, superimposed on a direct response due to direct energy deposition in cell nuclei. A quantitative model based on this approach is described for a-particle-induced in vitro oncogenic transformation. The model postulates that the oncogenic bystander response is a binary ‘‘all or nothing’’ phenomenon in a small sensitive subpopulation of cells, and that cells from this sensitive subpopulation are also very sen-sitive to direct hits from a particles, generally resulting in a directly hit sensitive cell being inactivated. The model is ap-plied to recent data on in vitro oncogenic transformation pro-duced by broad-beam or microbeam a-particle irradiation. Two parameters are used in analyzing the data for transfor-mation frequency. The analysis suggests that, at least for a-particle-induced oncogenic transformation, bystander effects are important only at small doses—here below about 0.2 Gy. At still lower doses, bystander effects may dominate the over-all response, possibly leading to an underestimation of low-dose risks extrapolated from intermediate doses, where direct effects dominate. q 2001 by Radiation Research Society

Localized Particle Concentration Measurement in Slurry Flows Using A-Scan Ultrasound Technique

In the design of slurry transport equipment, the effects of solid particle concentration on hydraulic performance and wear have to be considered. This study involves examining the acoustic properties of slurry flows such as velocity, backscatter and attenuation as a function of volume fraction of solid particles. Ultrasound A-mode imaging method is developed to obtain particle concentration in a flow of soda lime glass particles (diameter of 200 micron) and water slurry in a 1″ diameter pipe. Based on the acoustic properties of the slurry a technique is developed to measure local solid particle concentrations. The technique is used to obtain concentration profiles in homogeneous (vertical flow) and non-homogeneous (horizontal flow) slurry flows with solid particle concentrations ranging from 1–10% by volume. The algorithm developed utilizes the power spectrum and attenuation measurements obtained from the homogeneous loop as calibration data in order to obtain concentration profiles in other (i.e. non-homogenous) flow regimes. A computational study using FLUENT was performed and a comparison is made with the experimental results. A reasonable agreement between the experimental and computational results is observed.

Micro and Nano Chemical System on Chip

Integrated micro chemical systems have been expected as evolutional tools for high speed, functional and compact instrumentations for analysis, synthesis, bio and related sciences and technologies. We have developed general methods for micro integration of chemical systems on the basis of the concept being similar to electronics. In place of resistor, capacitor, and diode in IC, micro unit operations for mixing, extraction, phase separation, etc. have developed as integrated components of microchemical systems. There are two directions of our microchip chemical technologies. One is to make these technologies practical and to commercial use of micro-meter scale chemical system on chip. And the other one is to extend the method to nano-meter scale chemical experiment which is opening new horizon of chemical research tool.

Retinitis pigmentosa with iris coloboma due to <i>miR‐204</i> gene variant in a Chinese family

Abstract Purpose To characterize the phenotype and genotype of a Chinese family with autosomal‐dominant retinitis pigmentosa (RP) accompanied by iris coloboma. Methods The proband, a 34‐year‐old male, was examined with his family by using fundus photography, optical coherence tomography (OCT), autofluorescence, and full‐field electroretinography (ffERG). Genetic analyses were conducted through whole‐exome sequencing (WES) to screen for variations. Results Three members of this Chinese family were shown to be bilateral iris coloboma. The male proband and his mother exhibited typical RP feature. The proband's late grandfather had been documented manifestation of iris coloboma. The mode of inheritance was confirmed to be autosomal dominance. Through linkage analysis and WES, a heterozygous variation in the miR‐204 gene (n.37C&gt;T), a noncoding RNA gene, was identified in these three members. Conclusions In this third independent and the first Asian family, the existence of a miR‐204 variant associated with RP accompanied by iris coloboma was confirmed. Our findings reinforce the significance of miR‐204 as an important factor influencing visual function in the retina. When phenotypes like RP accompanied by iris coloboma in an autosomal‐dominant pattern, including in Chinese patients, miR‐204 aberrations should be considered.

Development of tourism in Poland: policy implications

This research note aims to discuss policy implications for the development of tourism in Poland. It takes as its premise that the country has considerable tourist potential, which has not been fully tapped. Hence, with emphasis placed on Poland's destination attractiveness, we identify weaknesses that hold back the growth of the tourism industry. It is argued that the development of various forms of tourism might foster the diversification of economic activity and encourage the creation of jobs, in particular in poorer rural or remote communities. For this to happen, however, a re-orientation of economic and environmental policies is called for.
