Humans' attachment to their mobile phones and its relationship with interpersonal attachment style

Humans have a biological predisposition to form attachment to social partners, and they seem to form attachment even toward non-human and inanimate targets. Attachment styles influence not only interpersonal relationships, but interspecies and object attachment as well. We hypothesized that young people form attachment toward their mobile phone, and that people with higher attachment anxiety use the mobile phone more likely as a compensatory attachment target. We constructed a scale to observe people's attachment to their mobile and we assessed their interpersonal attachment style. In this exploratory study we found that young people readily develop attachment toward their phone: they seek the proximity of it and experience distress on separation. People's higher attachment anxiety predicted higher tendency to show attachment-like features regarding their mobile. Specifically, while the proximity of the phone proved to be equally important for people with different attachment styles, the constant contact with others through the phone was more important for anxiously attached people. We conclude that attachment to recently emerged artificial objects, like the mobile may be the result of cultural co-option of the attachment system. People with anxious attachment style may face challenges as the constant contact and validation the computer-mediated communication offers may deepen their dependence on others. © 2016 Elsevier Ltd.

Modified Discrete Radon Transforms and Their Application to Rotation-Invariant Image Analysis

This paper presents two novel transforms based on the discrete Radon transform. The proposed transforms smartly solve two inherent problems of the Radon transform in rotation estimation in digital images, i.e., direction-dependency and nonhomogeneity, that come from the different numbers of pixels projected on a line for different directions and/or coordinates of a direction. While the first transform considers the sample mean operator on the same sets of pixels for a direction instead of summation in the discrete Radon transform, the second transform uses the mean operator on sets of pixels with the equal number of elements. In order to show the efficiency of the proposed transforms, we apply them on image collections from the Brodatz album for estimating the directional information. Experimental results show a significant increase in correct estimation as well as in the processing time compared to the conventional Radon transform
Pharmacodynamics, safety, and pharmacokinetics of BMS-663068, an oral HIV-1 attachment inhibitor in HIV-1-infected subjects.

BACKGROUND
BMS-663068 is a prodrug of the small-molecule inhibitor BMS-626529, which inhibits human immunodeficiency virus type 1 (HIV-1) infection by binding to gp120 and interfering with the attachment of virus to CD4+ T-cells.


METHODS
Fifty HIV-1-infected subjects were randomized to 1 of 5 regimen groups (600 mg BMS-663068 plus 100 mg ritonavir every 12 hours [Q12H], 1200 mg BMS-663068 plus 100 mg ritonavir every bedtime, 1200 mg BMS-663068 plus 100 mg ritonavir Q12H, 1200 mg BMS-663068 Q12H plus 100 mg ritonavir every morning, or 1200 mg BMS-663068 Q12H) for 8 days in this open-label, multiple-dose, parallel study. The study assessed the pharmacodynamics, pharmacokinetics, and safety of BMS-663068.


RESULTS
The maximum median decrease in plasma HIV-1 RNA load from baseline ranged from 1.21 to 1.73 log(10) copies/mL. Plasma concentrations of BMS-626529 were not associated with an antiviral response, while low baseline inhibitory concentrations and the minimum and average steady-state BMS-626529 plasma concentrations, when adjusted by the baseline protein binding-adjusted 90% inhibitory concentration (inhibitory quotient), were linked with antiviral response. BMS-663068 was generally well tolerated.


CONCLUSIONS
Administration of BMS-663068 for 8 days with or without ritonavir resulted in substantial declines in plasma HIV-1 RNA levels and was generally well tolerated. Longer-term clinical trials of BMS-663068 as part of combination antiretroviral therapy are warranted. Clinical Trials Registration.NCT01009814.
Development and Control of a High Maneuverability Wheeled Robot with Variable-Structure Functionality

Common wheeled robots face many difficulties when traveling in complex environments, especially its incapability to climb over obstacles higher than its wheel radius. Many alterations were made to these robots to allow them to travel in rough terrains or conquer high obstacles, nevertheless, most designs are complex in nature and lost several original wheeled robot advantages by gaining others. In this paper, we propose a novel wheeled type robot with variable structure functionality. It is designed with simple structure consisting of three main robot parts, the main body, the left and right wheel-arm units. The robot could achieve five locomotion modes that allows the robot to travel in various environments and climb over high obstacles. Moreover, the fast-speed advantage in flat floor condition that common wheeled robot originally hold is still remained. The confirmation of the effectiveness of the robot's maneuverability is shown by several experimental results
Prognostic impact of meningeal dissemination in primary CNS lymphoma (PCNSL): experience from the G-PCNSL-SG1 trial.

BACKGROUND
We evaluated the frequency and prognostic impact of meningeal dissemination (MD) in immunocompetent adult patients with primary central nervous system lymphoma treated in a randomized phase III trial.


PATIENTS AND METHODS
MD was evaluated at study entry and defined by lymphoma proof in the meningeal compartment detected by at least one of the following methods: cerebrospinal fluid (CSF) cytomorphology, detection of clonal B cells by IgH PCR in CSF or contrast enhancement of the leptomeninges on magnetic resonance imaging (MRI).


RESULTS
Data on MD were available in 415 patients, of those, MD was detected in 65 (15.7%): in 44/361 (12.2%) by CSF cytomorphology, in 16/152 (10.5%) by PCR and in 17/415 (4.1%) by MRI. Major patients' characteristics and therapy did not significantly differ between patients with MD (MD+) versus those without MD (MD-). There was a significant correlation of MD with CSF pleocytosis (>5/μl; P < 0.0001), but no correlation with CSF protein elevation (>45 mg/dl). Median progression-free survival was 6.7 months [95% confidence interval (CI) 0-14.5] in MD+ and 8.3 months (5.7-10.8) in MD- patients (P = 0.95); median overall survival was 21.5 months (95% CI 16.8-26.1) and 24.9 months (17.5-32.3), respectively (P = 0.98).


CONCLUSION
MD was detected infrequently and had no impact on outcome in this trial.
A Brief Tour Through Provenance in Scientific Workflows and Databases

Within computer science, the term provenance has multiple meanings, due to different motivations, perspectives, and assumptions prevalent in the respective communities. This chapter provides a high-level “sightseeing tour” of some of those different notions and uses of provenance in scientific workflows and databases.
Conflict and Performance in Global Virtual Teams

Increasing globalization and advances in communication technology have fuelled the emergence of global virtual teams (GVT). There is much potential for conflict in GVT as members work across cultural, geographical, and time boundaries. This study examines the antecedents of GVT conflict and the circumstances under which conflict affects team performance. An in-depth study of GVT conflict episodes was carried out using interviews, observations, communication logs, and documents. Based on findings from the teams under study interpreted in the light of prior literature, propositions are developed about the antecedents and impacts of GVT conflict as stated. GVT cultural diversity is likely to contribute to both task and relationship conflict, while functional diversity may result in task conflict. Large volume of electronic communication and lack of immediacy of feedback in asynchronous media can contribute to task conflict. Additionally, the relationship between task conflict and team performance is likely to be contingent upon task complexity and conflict resolution approach. The influence of relationship conflict on performance may depend on task interdependence and conflict resolution approach. The conflict resolution approach may in turn be determined by the nature of conflict attribution. These propositions have been synthesized into a model to guide future empirical research and GVT practice.
A novel compact single-feed dual-band circular polarization antenna

A new compact single-feed dual-band square-ring patch CP antenna with an unequal cross-slot ground plane is proposed. The size of the new antenna is compact and the simulated results show good performance. Also, it achieves a small frequency ratio.
Chlamydia, Mycoplasma and Ureaplasma infections in infertile couples and effects of these infections on fertility

In our study, we aimed to determine the prevalence of Chlamydia trachomatis, Mycoplasma hominis and Ureaplasma urealyticum infections among infertile couples and effects of these infections on infertility. Prevalence of Chlamydia, Mycoplasma, Ureaplasma antibodies and Chlamydia IgM antibodies and its effect on these agents’ sperm parameters, namely, morphology, density, and motility were investigated among a total of 212 patients including fertile and infertile couples. Chlamydia, Mycoplasma, Ureaplasma antigens were evaluated using ELISA in the cervical and urethral samples. Chlamydia IgM antibody was measured using micro-ELISA in blood samples. No difference was detected among the fertile and infertile groups in the serological investigation of urethral and cervical samples with respect to the prevalence of Chlamydia, Mycoplasma, Ureaplasma antigens and Chlamydia IgM antibody and sperm parameters (p > 0.05). There is no significant difference between fertile and infertile couples in terms of the prevalence of the above mentioned infections. Accordingly, during the infertility assessment, infertile couples should not be routinely screened for these infective agents without any clinically sound evidence.
Investigation of the Galvanic Mechanism for Localized Carbon Dioxide Corrosion Propagation Using the Artificial Pit Technique

Localized carbon dioxide (CO2) corrosion is the most dangerous type of internal corrosion to mild steel pipelines in the oil and gas industry since the penetration rate of localized corrosion can be one or more magnitudes higher than that of uniform corrosion. In this study, the focus is on propagation of localized CO2 corrosion on mild steel that occurs by a galvanic mechanism. A galvanic cell is established by the coupling of two distinct areas in a conductive CO2 solution: a bare steel surface and an iron carbonate (FeCO3) layer-covered steel surface. It was found that localized CO2 corrosion propagates when a stable difference in corrosion potential is established between the anode (bare steel surface) and the cathode (FeCO3-covered surface). Stable propagation will occur only when the conditions are in the “gray zone,” i.e., close to saturation with respect to FeCO3, when no significant FeCO3 dissolution nor precipitation is expected. Practically, this corresponds to when FeCO3 supersaturation (SSFeCO3) is in the range from 0.5 to 2. The key environmental factors that affect propagation of localized CO2 corrosion of mild steel are temperature, pH, partial pressure of CO2, salt concentration, and flow velocity. A protective FeCO3 layer forms at high temperature (>50°C); therefore, the galvanic mechanism of localized corrosion is valid only in this range. pH needs to be such that moderately protective FeCO3 layers form, typically at pH 5.5 to 6.5. Critical partial pressures of CO2 is around 0.1 bar to 2 bar, above this very protective FeCO3 films form at high temperature, giving a very low likelihood of localized attack. The solubility of FeCO3 increases with increasing salt concentration, making it more difficult to form protective FeCO3 layers and more likely to get localized corrosion propagation. Turbulent flow assists localized corrosion propagation by sweeping away corrosion products from the rapidly corroding steel surface and thereby preventing reformation of the protec-
Paediatric emergencies: non-traumatic abdominal emergencies

Presentation with acute abdominal pain or abdominal symptopathology is a very common cause of presentation of children to hospital. The causes are dependent in part on the age of the child, in part on the presence of previous surgery, and can be divided into those that relate to congenital abnormalities at whatever age they present, acquired disease and infection. Children, particularly young children are often poor historians, and therefore the clinical examination and the laboratory investigations are important in helping to come to a diagnosis. Primary imaging of abdominal emergencies in childhood is a radiograph of the abdomen, followed by ultrasound. Further imaging depends on the results of these studies. An ordered review of the abdomen radiograph is important if the salient features on X-ray are not to be missed. Practitioners should be competent with abdominal ultrasound in children and know where to seek the causes of disease, as these are different from those that are obtained in many instances in adults. Familiarity with the likely causes is important. The three commonest causes of acute abdominal pain in childhood are, in young infants, intussusception, appendicitis and mesenteric adenitis. In older children, inflammatory bowel disease and ovarian pathology are also included. This article details the approach to imaging and the salient features of some of the conditions.
Determination of Atropine ( Hyoscyamine ) Sulfate in Commercial Products by Liquid Chromatography with UV Absorbance and Fluorescence Detection : Multilaboratory Study

A liquid chromatographic (LC) method with 2 detection systems for determining atropine (hyoscyamine) sulfate in commercial products was tested in a multilaboratory study. Depending on the type of product, sample solutions are prepared in methanol or methanol–water (1 + 1). The standard solution contains about 1.0 mg atropine sulfate/100 mL and is prepared in the same solvent used in sample preparation. LC separations are performed on a 7.5 cm Novapak silica column. The mobile phase is prepared by mixing 970 mL methanol with 30 mL of a 1% aqueous solution of 1-pentanesulfonic acid, sodium salt. Detection is by 2 systems, UV absorbance detection at 220 nm and fluorescence detection with excitation at 255 nm and emission at 285 nm. The injection volume is 100 or 200 L. The following materials were used for the study: 2 separate samples of tablets labeled to contain 0.4 mg atropine sulfate, 2 separate samples of extended-release tablets labeled to contain 0.375 mg hyoscyamine sulfate, one sample of atropine sulfate injection labeled to contain 2 mg/mL, and one sample of 1% (v/v) atropine sulfate ophthalmic. Eight participants analyzed 2 separate portions of the 6 samples by both detection systems. A ninth participant analyzed the samples in duplicate but only by UV absorbance detection because of the unavailability of a fluorescence detector. The relative standard deviation (RSD) between laboratories ranged from 1.4 to 3.3% for samples of tablets and injections but higher for ophthalmic solutions (5.1–5.2%). A linearity study was conducted in the originating laboratory before the multilaboratory study with 5 solutions ranging in concentration from 0.80 to 1.20 mg atropine sulfate in 100 mL. Average recoveries were 100.0% by UV absorbance detection and 99.9% by fluorescence detection; the RSDs were 1.1 and 1.2%, respectively.
A GIS-Coupled Hydrological Model System for the Watershed Assessment of Agricultural Nonpoint and Point Sources of Pollution

This paper introduces AVSWAT, a GIS based hydrological system linking the Soil and Water Assessment Tool (SWAT) water quality model and ArcView Geographic Information System software. The ?main purpose of AVSWAT is the combined assessment of nonpoint and point pollUtion loading at the watershed scale. The GIS component of the system, in addition to the traditional functions of data acquisition, storage, organization and display, implements advanced analytical methods with enhanced flexibility to improve the hydrological characterization of a study watershed. Intuitive user friendly graphic interfaces, also part of the GIS component, have been developed to provide an efficient interaction with the model and the associated parameter databases, and ultimately to simplify water quality assessments, while maintaining and increasing their reliability. This is also supported by SWAT, the core of the system, a complex, conceptual, hydrologic, continuous model with spatially explicit parameterization, building upon the United State Department of Agriculture (USDA) modeling experience. A step-by-step example application for a watershed in Central Texas is also included to verify the capability and illustrate some of the characteristics of the system which has been adopted by many users around the world.

Familism : A cultural value with implications for romantic relationship quality in U . S . Latinos

Familism is a cultural value that emphasizes interdependent family relationships that are warm, close, and supportive. We theorized that familism values can be beneficial for romantic relationships and tested whether (a) familism would be positively associated with romantic relationship quality and (b) this association would be mediated by less attachment avoidance. Evidence indicates that familism is particularly relevant for U.S. Latinos but is also relevant for non-Latinos. Thus, we expected to observe the hypothesized pattern in Latinos and explored whether the pattern extended to non-Latinos of European and East Asian cultural background. A sample of U.S. participants of Latino (n 1⁄4 140), European (n 1⁄4 176), and East Asian (n 1⁄4 199) cultural background currently in a romantic relationship completed measures of familism, attachment, and two indices of romantic relationship quality, namely, partner support and partner closeness. As predicted, higher familism was associated with higher partner support and partner closeness, and these associations were mediated by lower attachment avoidance in the Latino sample. This pattern was not observed in the European or East Asian background samples. The implications of familism for relationships and psychological processes relevant to relationships in Latinos and non-Latinos are discussed. 1 University of California, Irvine, USA 2 University of California, Los Angeles, USA Corresponding author: Belinda Campos, Department of Chicano/Latino Studies, University of California, Irvine, 3151 Social Sciences Plaza A, Irvine, CA 92697, USA.

Technology innovations and architecture solutions for the next-generation optical access network

Although deployment of fiber to the home (FTTH) systems has been ongoing for over 5 years in certain markets, the industry is still in the early phases of what is expected to be a decades-long optical fiber–based access network build-out. Deployment so far has been largely opportunistic, as in greenfield deployment or copper rehab; competitive, as competitive local exchange carriers (CLECs), utilities, and small multiple systems operators (MSOs) roll out solutions; policy-driven, at the national or municipal level; and strategic, in some isolated cases of a few large carriers. In the coming years as the appetite for bandwidth continues to grow, fiber-based networks will become the only acceptable solution. FTTH technologies have already undergone several stages of evolution, from asynchronous transfer mode passive optical network (APON) to broadband PON (BPON), Ethernet PON (EPON), and Gigabit PON (GPON)—and they will continue to do so in the future. Continuous innovations will allow for a long term increase in bandwidth, an improved cost structure, and greater reach. Starting from current FTTH architectures, including PON, point-to-point (PP), active Ethernet (AE), this paper will focus on the next-generation architectures and supporting technologies that will be used in the future including 10 Gbps PON (10GPON), multi-lambda GPON, coarse wavelength division multiplexing (CWDM) PON, and dense WDM (DWDM)-PON. It will show the relative merits of each architecture, the required supporting technologies, and the role of these solutions in the long term evolution of access networks.
Using Internet nodes and routers onboard satellites

An Internet router was integrated into the UK-DMC remote-sensing satellite as a secondary experimental payload. This commercial product has been orbiting in space for over three years. We describe the integration of the router and satellite and the successful on-orbit testing of the router, which took place using the Virtual Mission Operations Center (VMOC) application as part of a larger systems internetworking exercise. Placing this Cisco router in Low Earth Orbit (CLEO) onboard a small satellite is one step towards extending the terrestrial networking model to the near-Earth space environment as part of a merged space-ground architecture.
Association study of Parkin gene polymorphisms with idiopathic Parkinson disease.

BACKGROUND
Previously, we detected linkage of idiopathic Parkinson disease (PD) to the region on chromosome 6 that contains the Parkin gene (D6S305; logarithm of odds score, 5.47) in families with at least one individual with age at onset younger than 40 years (families with early-onset disease). Further study demonstrated the presence of Parkin mutations in this data set. However, previous case-control studies have reported conflicting results regarding the role of more common Parkin polymorphisms as susceptibility alleles for idiopathic PD.


OBJECTIVE
To investigate the association of 7 previously studied Parkin single-nucleotide polymorphisms (SNPs) throughout the promoter and most of the open reading frame with PD in a large cohort of patients with primarily late-onset PD.


METHODS
One promoter, 3 intronic, and 3 exonic Parkin SNPs were genotyped in 1580 individuals belonging to 397 families, and their association with PD was evaluated using family-based association tests.


RESULTS
No significant association (P>.05) between PD and any Parkin SNP allele or genotype was detected. Haplotype analysis and stratification by age at onset or family history also failed to produce significant results.


CONCLUSIONS
These results suggest that these common variants of Parkin are not associated with PD in white patients, although Parkin mutations are known to cause early- and late-onset PD.
