Exploring the structure of library and information science Web space based on multivariate analysis of social tags

Introduction. This study examines the structure of Web space in the field of library and information science using multivariate analysis of social tags from the Website, Delicious.com. A few studies have examined mathematical modelling of tags, mainly examining tagging in terms of tri-partite graphs, pattern tracing and descriptive statistics. This study is one of the few studies to employ multivariate analysis in investigating dimensions of Web spaces based on social tagging data. Method. This study examines the post data collected from a set of library and information science related Websites bookmarked on Delicious.com using a Web crawler. Post data consist of the URL, usernames, tags and comments assigned by users of Delicious.com. The collected tag data were analysed based on multivariate methods, such as multidimensional scaling and structural equation modelling. Analysis. Collected data were first analysed using multidimensional scaling to explore initial relationships amongst the selected Websites. Then, confirmatory factor analysis based on structural equation modelling was employed to examine the hierarchical structure of the library & information science Web space. Results. Social tag data exhibit different dimensions in the Web space of the library and information science field. In addition, social tags confirmed the hierarchical structure of the field by showing significantly stronger relationships between the sites with similar characteristics. That is, the structure of the tagging data shows similar connections to those present in the real world. Conclusions. This study suggests a new statistical approach in social tagging and Web space analysis studies. Tag information can be used to explain the hierarchical structure of a certain domain. Methodologically, this study suggests that structural equation modelling can be a compelling method to explore hierarchal structures of nodes on the Web space.
Applying The Balanced Capacity Concept to DSL Systems

This paper investigates a fair resource allocation method in crosstalk limited DSL (digital subscriber line) systems. As a measure of fairness, the concept of balanced capacity (BC), introduced in T. Sartenaer et al. (2005), is used. BC corresponds to a point on the boundary of the capacity region where each user experiences the same relative loss with respect to his maximum capacity. This is especially useful in near-far situations where some users can experience a huge capacity loss if the allocation is performed according to the sum-rate criterion (or any similar criterion). Our goal is to propose efficient algorithms to compute the BC point in DSL systems for constraints on individual power spectrum densities. Results are reported for typical crosstalk limited cases and are compared to a resource allocation optimized for the sum rate. The proposed algorithm is shown to be of low complexity.
Harmonic Voltage Reduction Using a Series Active Filter Under Different Load Conditions

This paper proposes a series active filter using a simple control technique. The series active filter is applied as a controlled voltage source contrary to its common usage as variable impedance. It reduces the terminal harmonic voltages, supplying linear or even nonlinear loads with a good quality voltage waveform. The operation principle, control strategy, and theoretical analysis of the active filter are presented. These aspects were proven by the results of numerical simulations. Experimental results of the series active filter demonstrated its good performance under different load conditions
Globally Optimal Distributed Kalman Fusion With Local Out-of-Sequence-Measurement Updates

In a distributed multisensor fusion systems, observations produced by sensors can arrive at local processors out of sequence. The resulting problem at the central processor/fusion center-how to update current estimate using multiple local out-of-sequence-measurement (OOSM) updates - is a nonstandard distributed estimation problem. In this note, based on the centralized update algorithm with multiple asynchronous (1-step-lag) OOSMs see we firstly deduce the optimal distributed fusion update algorithm with multiple local asynchronous (1-step-lag) OOSM updates, which is proved, under some regularity conditions, to be equivalent to the corresponding optimal centralized update algorithm with all-sensor 1-step-lag OOSMs. Then, we propose an optimal distributed fusion update algorithm with multiple local arbitrary-step-lag OOSM updates.
How Much to Share with Third Parties? User Privacy Concerns and Website Dilemmas

Publishers websites are increasingly presenting content and services that are not created and managed by the website administrators themselves, but are provided by other third parties. While third party content and services provide value and utility to website users, this comes at the cost of user information being shared with the third party. Privacy concerns surrounding information leakage have been growing rapidly. With increasing concerns regarding online privacy and information disclosure, it is important to understand the factors that affect the level of sharing between publisher websites and third parties. In this study, we propose a two-sided economic model that captures the interaction between the users, publisher websites, and third parties. Specifically, we focus on the effect of privacy concerns on the sharing behavior of the publisher website and the impact of users’ privacy concerns on third party market concentration. We then analyze welfare aspects to provide insights on the impacts of industry regulations and policy on users, publisher websites, and third parties. We partially validate the model using an exploratory empirical analysis of publisher website third party sharing behavior and the structure of the industry. To the best of our knowledge, this study is among the first to analyze publisher website decision making in sharing user information with third parties.
2015 European guideline on the management of Chlamydia trachomatis infections

Chlamydia trachomatis infections, which most frequently are asymptomatic, are major public health concerns globally. The 2015 European C. trachomatis guideline provides: up-to-date guidance regarding broader indications for testing and treatment of C. trachomatis infections; a clearer recommendation of using exclusively-validated nucleic acid amplification tests for diagnosis; advice on (repeated) C. trachomatis testing; the recommendation of increased testing to reduce the incidence of pelvic inflammatory disease and prevent exposure to infection; and recommendations to identify, verify and report C. trachomatis variants. Improvement of access to testing, test performance, diagnostics, antimicrobial treatment and follow-up of C. trachomatis patients are crucial to control its spread. For detailed background, evidence base and discussions, see the background review for the present 2015 European guideline on the management of Chlamydia trachomatis infections (Lanjouw E, et al. Int J STD AIDS. 2015).
Large‐Area Polyimide/SWCNT Nanocable Cathode for Flexible Lithium‐Ion Batteries

A large-area flexible polymer electrode is fabricated using a new type of polyimide/single-walled carbon nanotube (SWCNT) nanocable composite. SWCNTs serve as the current collector and conductive network, and polyimide nanoparticles anchored on carbon nanotubes act as active materials. The electrode shows superior rate performance, good cycling stability, and high flexibility.
Flexible automation for the production of contactless power transfer systems for electric vehicles

The increasing electrification of the automotive power train leads to significant changes in automotive value chains, while sales potentials are still uncertain [1]. Due to their considerable advantages in regard to safety and convenience, contactless power transfer systems may be the basis for further increasing the customers' acceptance for electrified vehicle concepts [2]. Increasing market acceptance will require high volume production concepts for contactless power transfer systems. Thus, the importance of automated assembly and manufacturing technologies moves into the focus. Especially the winding process of the HF-litz wire coil structures shows potential for further rationalization. Therefore, it is the aim of this paper to present flexible automation concepts for this process.
An 8b 0.8kS/s configurable VCO-based ADC using oxide TFTs with Inkjet printing interconnection

Flexible electronic is a promising technology for flexible and large-area sensing IoT applications, where ADC is a fundamental component This paper proposes a configurable and flexible VCO-based ADC, implemented with Oxide Thin-Film Transistors(TFT) technology. A VCO with four connecting modes is designed to configure the VCO-based ADC working under different power and resolutions. An Inkjet printing interconnection technology is introduced to enable the configurability of ADC, even after all TFT transistors are fabricated. It allows the ADC to be customized for different applications and avoids fabrication failure of devices. Experimental results show that the proposed ADC achieves a 0.8kS/s sampling rate. Its power consumption ranges from 541 to 866uW with ENOB from 3 to 6b.
IGF-I bioactivity might reflect different aspects of quality of life than total IGF-I in GH-deficient patients during GH treatment.

CONTEXT No relationship has been found between improvement in quality of life (QOL) and total IGF-I during GH therapy. AIM Our aim was to investigate the relationship between IGF-I bioactivity and QOL in GH-deficient (GHD) patients receiving GH for 12 months. METHODS Of 106 GHD patients, 84 on GH treatment discontinued therapy 4 weeks before establishing baseline values and 22 were GH-naive. IGF-I bioactivity was determined by IGF-I kinase receptor activation assay, total IGF-I by immunoassay (Immulite), and QOL by the disease-specific Question on Life Satisfaction Hypopituitarism (QLS-H) module and by the general SF-36 questionnaire (SF-36Q). RESULTS IGF-I bioactivity increased after 6 months (-2.5 vs -1.9 SD, P < .001) and did not further increase after 12 months (-1.8 SD, P = .23); total IGF-I increased from -2.3 to -0.9 SD (P < .001) and to -0.6 SD (P = .005), respectively. QLS-H did not change over 12 months (-0.66 ± 0.16 to -0.56 ± 0.17 SD [P = .42] to -0.68 ± 0.17 SD [P = .22]). The mental component summary of the SF-36Q increased from 47.4 (38.7-52.8) to 50.2 (43.1-55.3) (P = .001) and did not further improve (49.4 [42.1-54.1], P = .19); the physical component summary did not change (47.5 [42.0-54.2] vs 47.0 [41.9-55.3], P = .91, vs 48.3 [39.9-55.4], P = .66). After 12 months, IGF-I bioactivity was related to QLS-H (r = 0.28, P = .01); total IGF-I was not (r = 0.10, P = .37). IGF-I bioactivity and total IGF-I were related to PCS (r = 0.35, P = .001; and r = 0.31, P = .003). CONCLUSION IGF-I bioactivity remained subnormal after GH treatment and was positively related to QLS-H, whereas total IGF-I was not. This suggests that IGF-I bioactivity reflects different aspects of QOL than total IGF-I in GHD patients during GH treatment.
Hydrological modelling of imperfectly gauged basins: a new challenge

Prediction in Ungauged Basins (PUB) is a recent initiative undertaken by the International Association of Hydrological Sciences (IAHS). As the biggest developing country in the world, China has to face the difficulty that many basins are ungauged or, at best, imperfectly gauged. This paper discusses major directions of research on PUB in China, and in particular the unit hydrograph methods applied to the prediction of flooding in ungauged basins in China. Moreover, this paper describes the advantages of using new systematic theories and methods that rely on computer technology and remote sensing. Numerical simulation models will be the new way for PUB. This paper suggests a comparison study between well-gauged and ungauged basins. Furthermore, some new theories and technologies used for ungauged basin simulation are appraised, such as distributed hydrological modelling, remote sensing, and four-dimensional data assimilation systems. Finally, some thoughts on hydrological studies in ungauged basins are presented.
Absence of glutathione peroxidase‐1 exacerbates cerebral ischemia‐reperfusion injury by reducing post‐ischemic microvascular perfusion

Mice deficient in the anti‐oxidant enzyme glutathione peroxidase‐1 (Gpx1) have a greater susceptibility to cerebral injury following a localized ischemic event. Much of the response to ischemia‐reperfusion is caused by aberrant responses within the microvasculature, including inflammation, diminished endothelial barrier function (increased vascular permeability), endothelial activation, and reduced microvascular perfusion. However, the role of Gpx1 in regulating these responses has not been investigated. Wild‐type and Gpx1−/− mice underwent focal cerebral ischemia via mid‐cerebral artery occlusion followed by measurement of cerebral perfusion via laser Doppler and intravital microscopy. Post‐ischemic brains in wild‐type mice displayed significant deficit in microvascular perfusion. However, in Gpx1−/− mice, the deficit in cerebral blood flow was significantly greater than that in wild‐type mice, and this was associated with significant increase in infarct size and increased vascular permeability. Ischemia‐reperfusion also resulted in expression of matrix metalloproteinase‐9 (MMP‐9) in endothelial cells. The absence of Gpx1 was associated with marked increase in pro‐MMP‐9 expression as well as potentiated MMP‐9 activity. Pre‐treatment of Gpx1−/− mice with the anti‐oxidant ebselen restored microvascular perfusion, limited the induction and activation of MMP‐9, and attenuated the increases in infarct size and vascular permeability. These findings demonstrate that the anti‐oxidant function of Gpx1 plays a critical role in protecting the cerebral microvasculature against ischemia‐reperfusion injury by preserving microvascular perfusion and inhibiting MMP‐9 expression.
Effects of Lower-Limb Strength Training on Agility, Repeated Sprinting With Changes of Direction, Leg Peak Power, and Neuromuscular Adaptations of Soccer Players

Abstract Hammami, M, Negra, Y, Billaut, F, Hermassi, S, Shephard, RJ, and Chelly, MS. Effects of lower-limb strength training on agility, repeated sprinting with changes of direction, leg peak power, and neuromuscular adaptations of soccer players. J Strength Cond Res 32(1): 37–47, 2018—We examined the effects on explosive muscular performance of incorporating 8 weeks strength training into the preparation of junior male soccer players, allocating subjects between an experimental group (E, n = 19) and a matched control group (C, n = 12). Controls maintained their regular training program, but the experimental group replaced a part of this schedule by strength training. Performance was assessed using running times (5, 10, 20, 30 and 40 m), a sprint test with 180° turns (S180°), a 9-3-6-3-9 m sprint with backward and forward running (SBF), a 4 × 5 m sprint test with turns, repeated shuttle sprinting, repeated changes of direction, squat (SJ) and counter-movement (CMJ) jumping, back half-squatting, and a force–velocity test. Electromyographic (EMG) activity of the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) muscles was recorded during jumping. Two-way ANOVA showed significant gains in E relative to C during the straight sprint (all distances). Scores of E increased substantially (p ⩽ 0.01) on S4 × 5 and SBF and moderately on S180°. Leg peak power, SJ, and CMJ were also enhanced, with significant increases in EMG activity. However, repeated-sprint parameters showed no significant changes. We conclude that biweekly strength training improves key components of performance in junior soccer players relative to standard in-season training.
Critical Review: Essential Fatty Acids on Shrimp Feeding

Four types of poly unsaturated fatty acids (PUFA) are essential for all shrimp species, linoleic (LOA, 18:2n-6), alfa-linolenic (ALA, 18:3n-3), eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3) acids. Moreover, the arachidonic acid (ARA, 20:4n-6), even when present, seems to be, in crustaceans, not so important or yet dispensable. It is relevant knowing that cholesterol as much as PUFA are not well absorbed when not followed by a substantial amount of lecithin, reaching 5% of the ration. The sum of PUFA reaches around 3% of the diet, even varying according to the species, stage and ration type. For Penaeus monodon, a complex mathematic model was formulated in order to describe the relationships between the requirements of the cited PUFA. Industries involved with feed production on this segment must possess its own adaptation for another species. On the other hand, biochemical knowledge on PUFA n-3 series compounds functions are yet very delayed in comparison to the advances on pharmaceutical industry that investigates the n-6 series, with its prevalence in humans. In this review, the term PUFA is generically used to include ALA, LOA, DPA, EPA, ARA and DHA.
Photonic-assisted endoscopic analysis of guided W-band pulses

We present a photonic-assisted time-domain measurement technique for exploring millimeter-wave propagation through a W-band waveguide. The electric fields, guided inside a rectangular waveguide, are sampled using a sub-millimeter-scale electro-optic probe. The probe is all-dielectric and sufficiently minute to enter into the waveguide through a probe-scale hole, thus minimally perturbing the original propagation of the fields. This photonic and endoscopic probing system provides access to time-domain internal fields, which is not been possible with a conventional oscilloscope.
Coronary microvascular dysfunction is highly prevalent in women with chest pain in the absence of coronary artery disease: results from the NHLBI WISE study.

BACKGROUND Chest pain in the absence of obstructive coronary artery disease (CAD) is common in women; it is frequently associated with debilitating symptoms and repeated evaluations and may be caused by coronary microvascular dysfunction. However, the prevalence and determinants of microvascular dysfunction in these women are uncertain. METHODS We measured coronary flow velocity reserve (coronary velocity response to intracoronary adenosine) to evaluate the coronary microvasculature and risk factors for atherosclerosis in 159 women (mean age, 52.9 years) with chest pain and no obstructive CAD. All women were referred for coronary angiography to evaluate their chest pain as part of the Women's Ischemia Syndrome Evaluation (WISE) study. RESULTS Seventy-four (47%) women had subnormal (<2.5) coronary flow velocity reserve suggestive of microvascular dysfunction (mean, 2.02 +/- 0.38); 85 (53%) had normal reserve (mean, 3.13 +/- 0.64). Demographic characteristics, blood pressure, ventricular function, lipid levels, and reproductive hormone levels were not significantly different between women with normal and those with abnormal microvascular function. Postmenopausal hormone use within 3 months was significantly less prevalent among those with microvascular dysfunction (40% vs 60%, P =.032). Age and number of years past menopause correlated with flow velocity reserve (r = -0.18, P =.02, and r = -0.30, P <.001, respectively). No significant associations were identified between flow velocity reserve and lipid and hormone levels, blood pressure, and left ventricular ejection fraction. CONCLUSIONS Coronary microvascular dysfunction is present in approximately one half of women with chest pain in the absence of obstructive CAD and cannot be predicted by risk factors for atherosclerosis and hormone levels. Therefore, the diagnosis of coronary microvascular dysfunction should be considered in women with chest pain not attributable to obstructive CAD.
Choice of test for comparing two groups, with particular application to skewed outcomes

We consider a clinical trial where a skewed outcome variable is to be compared between two groups. While comparison of sample means may lack power, we show that power also depends on the nature of the anticipated treatment effect. For any given distribution in the control arm, there is a family of true distributions in the intervention arm for which the most powerful test is a comparison of arithmetic means. Similar results hold for a comparison of geometric means, and approximately for the Wilcoxon rank sum test and a comparison of medians. We discuss how these methods could be used in planning the analysis of a clinical trial in which the intervention effect alters the shape of the distribution. These ideas are illustrated by a trial in community psychiatry, where the primary outcome (days in hospital) was highly skewed but the intervention was mainly expected to reduce the frequency of values in the tail. We show that a comparison of sample means is a reasonable choice in this case despite the skewness. Copyright © 2003 John Wiley & Sons, Ltd.
Occurrence of cirrhosis‐related complications is a time‐dependent prognostic predictor independent of baseline model for end‐stage liver disease score

Abstract: Background: The model for end‐stage liver disease (MELD) is used to prioritize cirrhotic patients awaiting liver transplantation. Many cirrhosis‐related complications are indications for transplantation but are not included in MELD. This study investigated the impact of these complications on survival and association with MELD.
CCL3 promotes angiogenesis by dysregulation of miR-374b/ VEGF-A axis in human osteosarcoma cells

Osteosarcoma is the most frequent bone tumor, characterized by a high metastatic potential. However, the crosstalk between chemokine (C-C motif) ligand 3 (CCL3), which facilitates tumor progression and metastasis. Vascular endothelial growth factor-A (VEGF-A), an angiogenesis inducer and a highly specific mitogen for endothelial cells, has not been well explored in human osteosarcoma. Here we demonstrate the correlation of CCL3 and VEGF-A expressions, quantified by immunohistochemistry, with the tumor stage of human osteosarcoma tissues. Furthermore, CCL3 promotes VEGF-A expression in human osteosarcoma cells that subsequently induces human endothelial progenitor cell (EPC) migration and tube formation. Phosphorylation of JNK, ERK, and p38 was found after CCL3 stimulation. In addition, JNK, ERK, and p38 inhibitors also abolished CCL3-induced VEGF-A expression and angiogenesis. We noted that CCL3 reduces the expression of miR-374b and miR-374b mimic by reversing CCL3-promoted VEGF-A expression and angiogenesis in vitro and in vivo. This study shows that CCL3 promotes VEGF-A expression and angiogenesis in human osteosarcoma cells by down-regulating miR-374b expression via JNK, ERK, and p38 signaling pathways. Thus, CCL3 may be a new molecular therapeutic target in osteosarcoma angiogenesis and metastasis.
