Cross-cultural differences between American and Chinese college students on self-disclosure on social media

The purpose of this study is to figure out the cross-cultural differences between American and Chinese college students in self-disclosure on social media sites. In particular, it will examine the influence of culture (especially collectivism and individualism dimensions) in both content (breath) and depth of self-disclosure on Facebook and Renren. Also, this study aims to ascertain gender differences in the influence of self-disclosure (breath and depth). This study applied collectivism versus individualism, one of Hofstede’s cultural dimensions, and self-disclosure from social penetration model to examine the cultural differences between U.S. and Chinese college students in self-disclosure on social media sites. The results showed that there exits the nationality difference in self-disclosure’s width and depth, implying that Chinese students self-disclose more in width and depth than American college students. Gender differences in self-disclosure’s width and depth were also found and supported by previous study. Females prefer to self-disclose more in width and depth than males in SNSs. But the gender differences across nationality were only partially supported by the study; only U.S. females tend to self-disclose in more width than U.S. males.
NAMING PLAN FOR AN INTERNET DIRECTORY SERVICE Filename: draft-ietf-ids-dirnaming-00.txt

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as ''work in progress. '' To learn the current status of any Internet-Draft, please check the ''1id-abstracts.txt'' listing contained in the Internet-Drafts Shadow Directories on ftp.is. co.za (Africa), nic.nordu. net (Europe), Abstract Application of the conventional X.500 approach to naming has, in the experience of the authors, proven to be an obstacle to the creation of directory services. We propose a new directory naming plan that leverages the strengths of the most popular and successful Internet naming schemes for naming objects in a hierarchical directory. This plan can, we believe, facilitate the creation of an Internet White Pages Service (IWPS) by overcoming the problems encountered by those using the conventional recommended X.500 approach to naming. 1.0 EXECUTIVE SUMMARY The conventional approach to naming taken by the X.500 community has, in the experience of the authors, shown itself to be an obstacle to the creation of directory services. The required registration infrastructure is either non-existent or largely ignored. The infrastructure that does exist is cumbersome to use and tends to produce counterproductive results. The attributes used for naming have been confusing for users and inflexible to managers and operators of directory services. We propose an alternative approach-which can co-exist with current X.500 naming practices-for the construction of the Internet White
Size Separation of Silica Particles using a Magnetite-Containing Gel-Packed Column

A magnetite-containing gel was prepared by water-in-oil radical polymerization of N,N-dimethylacrylamide and N,N’-methylenebisacrylamide in the presence of magnetite. The size of the prepared gel particles was 86 µm. The obtained magnetite-containing gel was packed in a column and first permeated with water, which revealed that the gel displayed a nonlinear response to pressure drop with increasing flow rate. Thus, the gel particles at the bottom of the column felt more pressure from the fluid than those at the top, causing greater deformation of the gel particles at the bottom of the column than at the top. The gaps between the packed gel particles functioned as pores to filter particles of appropriate size and morphology. An industrial silica particle suspension with particle sizes of 300 nm, 800 nm, and 10 µm was permeated through the gel layer. The smallest (300 nm) silica particles passed through the column. The filtered silica particles were recovered from the gel layer by using a magnet to separate the magnetite-containing gel from the filtered silica particles. This magnetite-containing gel has wide application prospects for the separation of not only ceramics but also other colloids.
Checkpoint/restart in practice: When ‘simple is better’

Efficient use of high-performance computing (HPC) installations critically relies on effective methods for fault tolerance. The most commonly used method is checkpoint/restart, where an application writes periodic checkpoints of its state to stable storage that it can restart from in the case of a failure. Despite the prevalence of checkpoint/restart, it is still not very well understood in practice how to set its key parameter, the checkpoint interval. Despite a large body of theoretical work, practitioners still rely on crude rules-of-thumb such as “checkpoint once every hour”. Our goal is to identify methods for optimizing the checkpointing process that are easy to use in practice and at the same time achieve high quality solutions. In particular, our paper makes the following contributions: We evaluate an array of methods for optimizing the checkpoint interval, some previously known as well as new ones that we propose, using real-world failure logs. We show that a very simple closed-form solution can easily be adapted for use in practice and achieves near-optimal performance. We also find that more complex solutions only negligibly improve performance based on real world traces. We show that simple back-of-the envelope formulas can be used to accurately estimate the wasted work in HPC systems, and make projections of future HPC systems and requirements for their efficient use.
Hydrochloric acid-impregnated paper for liquid metal microfluidics

We report a method of substantially improving lyophobicity of a paper against gallium-based liquid, using hydrochloric acid (HCl) impregnation. We also report an extremely simple fabrication of microfluidic channels on a HCl-impregnated paper for gallium-based liquid metal, Galinstan®. Paper has many favorable properties in microfluidic applications, such as low cost, abundant supply, easy fabrication, and flexibility. We evaluated lyophobicity of several papers by measuring static and dynamic contact angles with a goal of finding optimal super-lyophobic paper-based substrate for microfluidics applications. We found HCl-impregnated laser printer flattened paper towel shows appropriate super-lyophobicity. We performed a bouncing experiment of a Galinstan® droplet on the HCl-impregnated flattened paper substrate and demonstrated movement of a liquid metal droplet in microfluidic channels formed on the HCl-impregnated paper.
Fully automatic inpainting method for complex image content

A novel, fully automatic framework for restoration of unknown or damaged picture areas is presented. Diverse causes as an accident, manual removal, or transmission loss may have lead to the missing visual information. The challenge then consists in repairing the occluded or missing image regions in an undetectable way. Here, assumption is made that dominant structures are of salient relevance to the human perception. Hence, they are accounted for in the filling process by using tensor voting, which is a structure inference approach based on the Gestalt laws of proximity and good continuation. In fact, based on a new segmentation-based inference mechanism presented in this paper, missing textures crossing dominant structures are robustly recovered. An efficient post-processing step based on cloning via covariant derivatives improves the visual quality of the inpainted textures. The proposed method yields significantly better results than previous approaches.
An Electronic Publication Dedicated to Early Stellar Evolution and Molecular Clouds from the Editor Abstracts of Recently Accepted Papers Externally Illuminated Young Stellar Environments in the Orion Nebula: Hubble Space Telescope Planetary Camera and Uv Observations

Lately an increasing amount of Newsletters are returned with recipient unknown after the monthly mailing. Please do remember to send me an update of your new e-mail address when it changes, with over 750 recipients it is a very time consuming job to keep track of which addresses have permanent errors and which are just due to temporary problems. When the Newsletter has been returned three consecutive times from an address it is deleted from the mailing list. I have been travelling extensively in recent months, and although I do my best to keep track of the abstracts received, it may occur that an abstract is lost. If this should happen to you, please accept my apology and send it once again. We present new 0.05 (22 AU) resolution narrow-band Hubble Space Telescope Planetary Camera images of externally illuminated young stellar objects embedded in the Orion Nebula. We also present 0.02 (9 AU) resolution UV images of 7 externally illuminated proto-stellar environments and the first UV spectra that cover the spectral range between 1400 and 3000Å. We discuss 43 objects for which the angular resolution has been improved over previous data by more than a factor of two. These young stellar objects are either embedded inside the Orion Nebula and externally illuminated by the Trapezium stars or located in front of the nebula and seen in silhouette. The visibility of young stars surrounded by diffuse matter is dominated by intense line emission from ionization fronts propagating into material photo–ablated from circumstellar disks by soft UV radiation. Near the Trapezium stars, the electron density at these ionization fronts is around 10 5 to 10 6 cm −3 and the radial intensity profiles of emission lines decrease roughly as r −3 , consistent with an approximately constant velocity diverging flow with an r −2 density profile. However, some radial intensity profiles are better fit with an exponential function. Low ionization fraction near the ionization front and the heating and acceleration of the photo–ablation flow by the conduction of heat from the shocked θ 1 Orionis C stellar wind bubble into the photo–ablation flow can explain deviations from the r −3 intensity profiles. Many young stars located within 30 of θ 1 Orionis C are surrounded by concentric arcs of [Oiii] and Hα emission located 0.5 to 3 from the ionization-front facing θ 1 Orionis C. These arcs may trace bow shocks formed …
Limited extracellular but complete intracellular acid-base regulation during short-term environmental hypercapnia in the armoured catfish, Liposarcus pardalis

SUMMARY Environmental hypercapnia induces a respiratory acidosis that is usually compensated within 24-96 h in freshwater fish. Water ionic composition has a large influence on both the rate and degree of pH recovery during hypercapnia. Waters of the Amazon are characteristically dilute in ions, which may have consequences for acid-base regulation during environmental hypercapnia in endemic fishes. The armoured catfish Liposarcus pardalis, from the Amazon, was exposed to a water PCO2 of 7, 14 or 42 mmHg in soft water (in μmol l-1: Na+, 15, Cl-, 16, K+, 9, Ca2+, 9, Mg2+, 2). Blood pH fell within 2 h from a normocapnic value of 7.90±0.03 to 7.56±0.04, 7.34±0.05 and 6.99±0.02, respectively. Only minor extracellular pH (pHe) recovery was observed in the subsequent 24-96 h. Despite the pronounced extracellular acidosis, intracellular pH (pHi) of the heart, liver and white muscle was tightly regulated within 6 h (the earliest time at which these parameters were measured) via a rapid accumulation of intracellular HCO3-. While most fish regulate pHi during exposure to environmental hypercapnia, the time course for this is usually similar to that for pHe regulation. The degree of extracellular acidosis tolerated by L. pardalis, and the ability to regulate pHi in the face of an extracellular acidosis, are the greatest reported to date in a teleost fish. The preferential regulation of pHi in the face of a largely uncompensated extracellular acidosis in L. pardalis is rare among vertebrates, and it is not known whether this is associated with the ability to air-breathe and tolerate aerial exposure, or living in water dilute in counter ions, or with other environmental or evolutionary selective pressures. The ubiquity of this strategy among Amazonian fishes and the mechanisms employed by L. pardalis are clearly worthy of further study.
A Heuristic Resource Scheduling Algorithm of Cloud Computing Based on Polygons Correlation Calculation

Cloud computing provides utility-oriented IT services for users worldwide, and it enables offering various kinds of applications to consumer in scientific or business field based on a pay-as-you-go model. Although cloud computing is still in its infancy, the scale of cloud infrastructure is expanding fast, which result in huge energy consumption and operating costs. Due to the complex architecture of cloud infrastructure, it is hard to evaluate and optimize energy consumption of cloud infrastructure in a non-intrusive manner under varying application, user configurations and requirements. In this paper, we present Bin-Balancing Algorithm (BBA), an innovative resource scheduling algorithm for private clouds that integrating the advantages of both bin packing solutions and polygons correlation calculations. BBA is designed to optimize energy consumption, while considering the task deadline, host PE (processing element), memory and bandwidth. Polygons correlation calculation integrated in BBA is used to meet the elastic characteristics of cloud computing services. BBA is validated and well compared with existing resource scheduling algorithms in Cloud Sim toolkit. The results demonstrate that BBA can save energy in cloud infrastructure while balancing the loss of performance and SLA of cloud users.
DoF analysis of the K-user MISO broadcast channel with hybrid CSIT

We consider a K-user multiple-input single-output (MISO) broadcast channel (BC) where the channel state information (CSI) of user i(i = 1, 2, ., K) may be either instantaneously perfect (P), delayed (D) or not known (N) at the transmitter with probabilities λ<sub>P</sub><sup>i</sup>, λ<sub>D</sub><sup>i</sup> and λ<sub>N</sub><sup>i</sup>, respectively. In this setting, according to the three possible CSIT for each user, knowledge of the joint CSIT of the K users could have at most 3<sup>K</sup> states. Although the results by Tandon et al. show that for the symmetric two user MISO BC (i.e., λ<sub>Q</sub><sup>i</sup> = λ<sub>Q</sub>, ∀<sub>i</sub> ∈ {1, 2}, Q ∈ {P, D, N}), the Degrees of Freedom (DoF) region depends only on the marginal probabilities, we show that this interesting result does not hold in general when K ≥ 3. In other words, the DoF region is a function of all the joint probabilities. In this paper, given the marginal probabilities of CSIT, we derive an outer bound for the DoF region of the K-user MISO BC. Subsequently, we investigate the achievability of the outer bound in some scenarios. Finally, we show the dependence of the DoF region on the joint probabilities.
VLSI module placement based on rectangle-packing by the sequence-pair

The earliest and the most critical stage in VLSI layout design is the placement. The background is the rectangle packing problem: given a set of rectangular modules of arbitrary sizes, place them without overlap on a plane within a rectangle of minimum area. Since the variety of the packing is uncountably infinite, the key issue for successful optimization is the introduction of a finite solution space which includes an optimal solution. This paper proposes such a solution space where each packing is represented by a pair of module name sequences, called a sequence-pair. Searching this space by simulated annealing, hundreds of modules have been packed efficiently as demonstrated. For applications to VLSI layout, we attack the biggest MCNC benchmark ami49 with a conventional wiring area estimation method, and obtain a highly promising placement.
Research Article Clinical Characteristics and Prognosis of Incidentally Detected Lung Cancers

Objective. To evaluate clinical characteristics and outcomes in incidentally detected lung cancer and in symptomatic lung cancer. Material and Methods. We designed a retrospective study including all patients undergoing pulmonary resection with a curative intention for NSCLC. They were classified into two groups according to the presence or absence of cancer-related symptoms at diagnosis in asymptomatic (ASX)—incidental diagnosis—or symptomatic. Results. Of the 593 patients, 320 (53.9%) were ASX. In 71.8% of these, diagnosis was made by chest X-ray. Patients in the ASX group were older (í µí± = 0.007), had a higher prevalence of previous malignancy (í µí± = 0.002), presented as a solitary nodule more frequently (í µí± < 0.001), and were more likely to have earlier-stage disease and smaller cancers (í µí± = 0.0001). A higher prevalence of incidental detection was observed in the last ten years (í µí± = 0.008). Overall 5-year survival was higher for ASX (í µí± = 0.001). Median survival times in pathological stages IIIB-IV were not significantly different. Conclusion. Incidental finding of NSCLC is not uncommon even among nonsmokers. It occurred frequently in smokers and in those with history of previous malignancy. Mortality of incidental diagnosis group was lower, but the better survival was related to the greater number of patients with earlier-stage disease.
The Diagnostic Value of DNA Methylation in Leukemia: A Systematic Review and Meta-Analysis

Background Accumulating evidence supports a role of DNA methylation in the pathogenesis of leukemia. The aim of our study was to evaluate the potential genes with aberrant DNA methylation in the prediction of leukemia risk by a comprehensive meta-analysis of the published data. Methods A series of meta-analyses were done among the eligible studies that were harvested after a careful filtration of the searching results from PubMed literature database. Mantel-Haenszel odds ratios and 95% confidence intervals were computed for each methylation event assuming the appropriate model. Results A total of 535 publications were initially retrieved from PubMed literature database. After a three-step filtration, we harvested 41 case-control articles that studied the role of gene methylation in the prediction of leukemia risk. Among the involving 30 genes, 20 genes were shown to be aberrantly methylated in the leukemia patients. A further subgroup meta-analysis by subtype of leukemia showed that CDKN2A, CDKN2B, ID4 genes were significantly hypermethylated in acute myeloid leukemia. Conclusions Our meta-analyses identified strong associations between a number of genes with aberrant DNA methylation and leukemia. Further studies should be required to confirm the results in the future.
Author ' s personal copy Bioremediation of heavy metals by growing hyperaccumulaor endophytic bacterium Bacillus sp

Heavy metal bioremediation by a multi-metal resistant endophytic bacteria L14 (EB L14) isolated from the cadmium hyperaccumulator Solanum nigrum L. was characterized for its potential application in metal treatment. 16S rDNA analysis revealed that this endophyte belonged to Bacillus sp. The hormesis of EB L14 were observed in presence of divalent heavy metals (Cu (II), Cd (II) and Pb (II)) at a relatively lower concentration (10 mg/L). Such hormesis was the side effect of abnormal activities increases of ATPase which was planned to provide energy to help EB L14 reduce the toxicity of heavy metals by exporting the cations. Within 24 h incubation, EB L14 could specifically uptake 75.78%, 80.48%, 21.25% of Cd (II), Pb (II) and Cu (II) under the initial concentration of 10 mg/L. However, nearly no chromium uptake was observed. The mechanism study indicated that its remediation efficiencies may be greatly promoted through inhibiting the activities of ATPase. The excellent adaptation abilities and promising remediation efficiencies strongly indicated the superiority of this endophyte in heavy metal bioremediation at low concentrations, which could be useful for developing efficient metal removal system. 2010 Elsevier Ltd.

Dry eye: prevalence and attributable risk factors in a hospital-based population.

PURPOSE To study the prevalence of dry eye in a hospital-based population and to evaluate the various risk factors attributable to dry eye. MATERIALS AND METHODS In this cross-sectional study, 500 patients above 20 years of age were screened randomly for dry eye. A 13-point questionnaire, Lissamine Green test, Tear film break-up time (TBUT), Schirmer's test and presence of strands/filaments were used to diagnose dry eye. The diagnosis was made when at least three of the tests were positive. The role of air pollution, sunlight, excessive winds, smoking, drugs and refractive status as dry eye risk factors was assessed. RESULTS Ninety-two (18.4%) patients had dry eye. Dry eye prevalence was maximum in those above 70 years of age (36.1%) followed by the age group 31-40 years (20%). It was significantly higher (P = 0.024) in females (22.8%) than in males (14.9%), more common in rural residents (19.6%) than in urban (17.5%) and highest among farmers/labourers (25.3%). A 2.15 fold increase was found in the odds for dry eye in those exposed to excessive wind, 1.91 fold to sunlight exposure, 1.42 to smoking, 1.38 to air pollution and 2.04 for persons on drugs. Dry eye prevalence was 14% in emmetropes, 16.8% in myopes and 22.9% in hypermetropes. It was 15.6% in those with corrected and 25.3% in those with uncorrected refractive errors. CONCLUSION Dry eye is an under-diagnosed ocular disorder. Reduction in the modifiable risk factors of dry eye is essential to reduce its prevalence.
The effect of high and low contraction velocity training on cross education and muscle hypertrophy

The purpose of this study was twofold: 1. To determine the effect of isokinetic eccentric training at high and low contraction velocity on cross education, and 2. To determine the effect of isokinetic eccentric and concentric training at high and low contraction velocity on muscle hypertrophy. Cross Education is defined as an increase in strength of the untrained (contralateral) limb after a period of unilateral (single limb) resistance training. The effect is especially evident after eccentric training. Muscle hypertrophy is the increase in muscle size. Twenty-six untrained volunteer subjects (11 males and 15 females, age 18-36) were randomized into either a fast velocity (180°/s) training group (FAST) or a slow velocity (30°/s) training group (SLOW), where they would complete two eight-week phases of unilateral isokinetic resistance training of the elbow flexors muscle group. Each training phase was separated by a five-week wash out phase. Phase I included only eccentric training of either the right or left arm (randomized), and Phase II included only concentric isokinetic training of the opposite arm. Ten additional subjects (2 males and 8 females) served as non-training controls (CTR). Pre and post elbow flexors peak torque in both arms at eccentric fast (180°/s) and slow (30°/s), and concentric fast (180°/s) and slow (30°/s) velocity was measured on a Biodex isokinetic dynamometer. Pre and post elbow flexors muscle thickness in both arms was measured by B-mode muscle ultrasound. Electromyography (EMG) measurements were taken from the elbow flexors of both arms during a single training session in both phases of the experiment. At the completion of eccentric training at the end of Phase I, cross education could be analyzed. Fast velocity eccentric training resulted in significant cross education (13%; p< .05), which was specific to the training
