Impact of topology control on capacity of wireless ad hoc networks

Capacity based topology management is essential for a wireless ad hoc network due to its limited capacity so that topology control becomes indispensable to deploy large wireless ad hoc networks. This paper discusses the impact of topology control on network capacity by introducing a new definition of the expected capacity that is first analyzed in the perspective of cross layer optimization. Based on the analytical result, optimal schemes for neighbor selection and transmission power control, which are two functions of topology control, are studied to maximize the capacity. An optimistic conclusion indicates that topology control with stable node degree renders the capacity not to decrease with the increase of the number of nodes present in the network. The analytical results in this paper can provide a guideline for the design of topology control schemes.
Carbon savings of demand side response of a UK energy aggregator.

We report carbon emissions and savings (tonnesCO2) of the STOR programme based on data from a UK demand response aggregator company that utilises diesel generators, CHP and turn down methods. Short-Term Operating Reserve, STOR, is one of the Demand Side Response (DSR) programme that are being run by the National Grid in the UK. The purpose of STOR programme is to reduce the load on the energy system by means of various subsitution and reduction techniques. In particular, STOR allows its subscribed providers to generate substituting power. In the STOR programme we study carbon savings based on data obtained from a UK based response aggregator company. This company provides various types of intervention (using diesel generators, Combined-Heat and Power (CHP) and demand reduction (turn-down)) at times of peak demand. Whether such DSR produces carbon savings or not, depends on the used technologies, as well as the scale of the interventions.
Firearm identification based on rotation invariant feature of cartridge case

This paper, proposes firearm identification method based on rotation invariant feature of cartridge case image. The rotation invariance feature is represented by the absolute value of Fourier coefficients of polar image of cartridge case on circles with different radii. The absolute value of Fourier coefficients is considered as the individual feature of the particular gun. Finally, the firearm can be identified by the distance between the absolute value of Fourier coefficients obtained from the reference cartridge case and the cartridge case to be identified. The firearm identification experiments are given to show the effectiveness of the proposed method.
The Dimerization Property of Glutathione S-Transferase Partially Reactivates Bcr-Abl Lacking the Oligomerization Domain*

Bcr-Abl oncoproteins are responsible for the pathogenesis of human leukemias with a reciprocal chromosome translocation t(9;22). The amino-terminal Bcr sequence has a potential to form a homotetramer (tetramer domain), and destructions of the tetramer domain cause a complete loss of biological activities in Bcr-Abl. Here we show that Bcr-Abl in which the tetramer domain is replaced with glutathione S-transferase (GST) with a dimerizing ability (GST/Bcr-Abl-(Δ1-160)) can no longer induce an interleukin-3 (IL-3) independence in Ba/F3 cells or transform mouse bone marrow cells but still retains by 30–40% the ability to transform Rat1 cells. Compared with the wild type Bcr-Abl, autophosphorylation of GST/Bcr-Abl-(Δ1-160) in vivo was reduced by more than 50%. The Grb-2 binding to GST/Bcr-Abl-(Δ1-160) was 50% reduced in Rat1 cells and undetectable in Ba/F3 cells. In Rat1 cells expressing GST/Bcr-Abl-(Δ1-160), phosphotyrosine contents of p62 and Shc were 70% decreased.
Breast milk-acquired cytomegalovirus infection in very low birth weight infants

Perinatal transmission of human cytomegalovirus (HCMV) infection in very low birth weight (VLBW) premature infants can lead to serious clinical symptoms and it has ben increasingly recognized that breast milk is the most frequent route of transmission. Breast milk is considered ideal food for newborns because of its nutritional value and anti-infectious components, but it can also be vehicle for viral and bacterial infection. The majority of HCMV seropositive mothers shed the virus into their breast milk and can transmit infection to their offspring. Perinatally acquired infections in full-term neonates are usually asymptomatic without sequelae due to protective maternal HCMV-specific antibodies received during pregnancy. In contrast, VLBW preterm infants are at risk of symptomatic infection with neutropaenia, thrombocytopaenia, sepsis-like syndrome and, less frequently, pneumonia and enteric infection. Postnatally acquired infection seems to spontaneously resolve without altering the clinical outcome. Ganciclovir treatment is restricted to severe symptomatic infections. Preterm infants with a gestational age <30 weeks, or with a birth weight <1000 g, are at greater risk of severe postnatal symptomatic HCMV infection, transmitted via maternal milk. The pasteurization of breast milk entirely eliminates infectivity and prevents virus transmission but alters nutritional and immunological milk properties, and freezing reduces, but does not eradicate, infectivity. Most authors encourage fresh maternal breastfeeding because its beneficial effects outweigh the risk of a transient infection, sequelae-free. Nevertheless, an individual decision based on the condition of health of the infant is important.
Preparation and cellular targeting study of VEGF-conjugated PLGA nanoparticles

Abstract Vascular endothelial growth factor receptor (VEGFR) is over-expressed on a variety of tumour cells and tumour neovasculature, and so becomes well-documented target for cancer treatment. This study was designed to evaluate the cellular targeting and anti-tumor potency of VEGF-conjugated nanoparticles (VEGF-NPs). The poly-lactic-co-glycolic acid nanoparticles were prepared using the emulsion-solvent evaporation method and the VEGF was conjugated on surface of nanoparticles by covalent coupling method. The obtained particles were found to be of spherical shape exhibiting a size of 710 nm and VEGF conjugation efficiency was 16.6%. The results in vitro test showed that VEGF-NPs were more associated to Human Umbilical Vein Endothelial Cells by binding to VEGFR. In vitro cell proliferation test, IC50 showed the superior antiproliferative activity of paclitaxel-loaded VEGF-NPs over unconjugated nanoparticles and native paclitaxel due to higher cellular association on tumour cells. So, the VEGF-NPs offer a promising active targeting carrier for tumour selective treatment.
Genius Loci: digital heritage augmentation for immersive performance

Genius Loci is an art installation and a theater play based on audiovisual augmented reality combined with contemporary writings and religious texts. The scenography takes place in a disused church and begins with a dialog between a contemporary author in residence and the ghost of a Carthusian monk during which the graphical rendering of historical hypotheses is progressively revealed. In the second part, the silhouette of the monk emerges from contemporary visuals that combine fluid and animated graphical patterns anchored to the church geometry. After saying a psalm, the monk vanishes in an apocalyptic audiovisual crescendo. Both historical and contemporary visuals are animated spatial augmented reality installations based on 3D scans of the church enriched with historical furniture and ornamentation. This study shows how digitalised heritage can be used for situated performance, and offers insights on artistic and technological issues that can ensure a better immersion of the audience through enhanced believability and empathy with the performance.

Mindfulness and Sport Participation in College Students A Senior Honors Thesis Presented in Fulfillment of the Requirements for Graduation with Distinction in the College of Education and Human Ecology at The Ohio State University

Mindfulness is the increased ability to be aware and attentive to what is happening in the moment. The concept of mindfulness embodies being conscious of the present and not being in an automatic mode. Mindfulness training could have a positive impact on athletic performance, injury prevention, and recovery time in athletes, but differences among mindfulness levels in athletes is currently not well understood. The purpose of this study was to examine levels of mindfulness among athletes versus non athletes as well as examine whether differences in mindfulness exist between individual sport athletes and team sport athletes. Undergraduate student volunteers (n= 398) completed questionnaires to assess mindfulness and sport participation. Data analysis was conducted to determine whether differences in mindfulness exist between athletes and non-athletes and between individual versus team sport athletes. No significant differences in mindfulness were found based on athletic status. A significant difference was found based on gender, however; males in the sample reported higher levels of mindfulness than females. Further research should focus on self identified athlete status compared to researcher identified athlete status. Researchers should continue and look at these paradigms of mindfulness and athlete status to understand the potential for mindfulness-based interventions to enhance recovery and performance among athletes.
Device-based Adaptation of Visualizations in Smart Environments

Smart environments are beginning to have a large impact to collaborative group work in business and science. The multiuser and multi-display character of these group work environments presents a novel challenge for information visualization, namely, the adaptation of graphical representations of data to specific target devices in the environment. In this paper, we discuss a general strategy for an automated device-based adaptation of visualizations. We report interesting preliminary results of our adaptation strategy for conventional scatterplots used within a service-oriented visualization framework.
Multiple Burials in Ancient Societies: Theory and Methods from Egyptian Archaeology

The paper aims at providing theoretical models and data interpretation applied to multiple burials. Challenging the current fuzzy definition of multiple burials in ancient societies, the paper proposes a more accurate classification of multiple burials, with particular reference to ancient Egypt funerary culture, based on two main parameters, which may have influenced the association of bodies: p1) architecture; p2) time span, and three flexible sub-parameters that may be used to customize different scenarios, on occasion: sp1) number of deceased; sp2) age of deceased; sp3) nature of death/deposition. The body has been often considered the real ontological centre of the burial itself with all of the other countable objects intended as radiating projections supporting the body-nucleus. The practice of multiple burials disrupts such a perception as it juxtaposes horizontal, multidirectional perspectives: the role of a new body entering among older bodies and objects, and of the multiple bodies and objects themselves. The study of multiple burials, if correctly framed, can lead to insights into different religious, social, and economic reasons behind the mortuary programmes within a society. For instance, sequential multiple burials reinforce the transformation of dead bodies into part of the burial equipment itself, reducing the centrality of the body and disrupting the narrative tied to individual biographies, increasing an ‘artefactual’ perception.
EICA at SemEval-2017 Task 4: A Simple Convolutional Neural Network for Topic-based Sentiment Classification

This paper describes our approach for SemEval-2017 Task 4 - Sentiment Analysis in Twitter (SAT). Its five subtasks are divided into two categories: (1) sentiment classification, i.e., predicting topic-based tweet sentiment polarity, and (2) sentiment quantification, that is, estimating the sentiment distributions of a set of given tweets. We build a convolutional sentence classification system for the task of SAT. Official results show that the experimental results of our system are comparative.
Data integration and visualisation for demanding marine operations

Marine operations face the major challenge of increased complexity. Much more data are being collected for diagnostic and monitoring purposes with sensors on board a vessel. However, due to the lack of easy data presentation and interaction, the crew members are overwhelmed by the large volume of information and alert messages, causing serious information overload problems. In this paper, we explore data integration and visualisation techniques for maritime operations and present a proof-of-concept prototype using real offline data from our industrial collaborators. This work is an important part of our initial efforts towards a visual analytics framework for maritime operations.
Malignant Catarrhal Fever in a Captive American Bison (Bison Bison) in Italy

Malignant catarrhal fever (MCF) is a fatal, systemic disease of cattle and other domestic and wild ruminants that, in Europe, is caused by Ovine herpesvirus 2 (OvHV-2). American bison (Bison bison) are highly susceptible to the disease. An adult American bison, housed in a zoo in southern Italy in close cohabitation with a group of domestic sheep (Ovis aries aries) displayed clinical signs that resembled the acute form of MCF. By real-time polymerase chain reaction, OvHV-2 DNA was detected intravitam in blood, in nasal and ocular swabs, and postmortem in tissue samples of the bison. By indirect fluorescent antibody test, high MCF antibody titers were found in the bison serum. Ovine herpesvirus 2 DNA and antibodies were also found in blood samples from the domestic sheep, thus suggesting a potential role of these animals as a source of the infection. To the authors' knowledge, this is the first MCF case in captive ruminants in Italy and the second confirmed case in captive bison of European zoos.

Factors associated with breast self-examination among Thai women living in rural areas in Northeastern Thailand.

OBJECTIVE To identify factors associated with monthly breast self-examination (BSE) performance among Thai women living in rural areas, Northeastern Thailand. MATERIAL AND METHOD This present cross-sectional study was conducted during April to July 2008. A random sample of 705 women aged 20 to 64 years living in the rural areas of Northeastern region was interviewed using a structured questionnaire seeking information on demography, prior experience of BSE, knowledge (of breast cancer and breast examination techniques) and health belief Logistic regression was performed to identify the potential predictors of monthly BSE performance. RESULTS Seventy-five percent of women had performed BSE in the last year, and only 49% had performed BSE monthly. Monthly BSE performance was associated with having heard of BSE (OR = 2.8; 95% CI: 1.1-6.9), been taught to perform BSE (OR = 2.4; 95% CI: 1.5-3.7), higher knowledge about breast cancer and BSE procedures (OR = 2.4; 95% CI: 1.7-3.5), and higher confidence in one's ability to perform BSE (OR = 4.4; 95% CI: 3.0-6.4). CONCLUSION To increase monthly BSE performance among Thai women living in the Northeastern rural areas, health officers should address women levels of accurate knowledge of breast cancer, provide training in BSE procedures, and advocate women' confidence in performing BSE.
Combining Neurotrophin-Transduced Schwann Cells and Rolipram to Promote Functional Recovery from Subacute Spinal Cord Injury

Following spinal cord injury (SCI), both an inhibitory environment and lack of intrinsic growth capacity impede axonal regeneration. In a previous study, prevention of cyclic adenosine monophosphate (AMP) hydrolysis by the phosphodiesterase-4 inhibitor rolipram, in combination with Schwann cell (SC) grafts, promoted significant supraspinal and proprioceptive fiber growth and/or sparing and improved locomotion. In another study, transplanted SCs transduced to generate a bifunctional neurotrophin (D15A) led to significant increases in graft SCs and axons, including supraspinal and myelinated axons. Here we studied the growth and myelination of local and supraspinal axons and functional outcome following the combination of rolipram administration and neurotrophin-transduced SC implantation after SCI. Rolipram was administered subcutaneously for 4 weeks immediately after contusion at vertebral T8 (25.0-mm weight drop, MASCIS impactor). GFP or GFP-D15A-transduced SCs were injected into the injury epicenter 1 week after SCI. GFP-D15A SC grafts and GFP SC grafts with rolipram contained significantly more serotonergic fibers compared to GFP SCs. SC myelinated axons were increased significantly in GFP SC with rolipram-treated animals compared to animals receiving SCI alone. Rolipram administered with either GFP or GFP-D15A SCs significantly increased numbers of brain stem-derived axons below the lesion/implant area and improved hindlimb function. Compared to the single treatments, the combination led to the largest SC grafts, the highest numbers of serotonergic fibers in the grafts, and increased numbers of axons from the reticular formation below the lesion/implant area and provided the greatest improvement in hindlimb function. These findings demonstrate the therapeutic potential for a combination therapy involving the maintenance of cyclic AMP levels and neurotrophin-transduced SCs to repair the subacutely injured spinal cord.
STRESS-STRAIN ANALYSIS OF RESTORED FIRST MOLAR TOOTH WITH CAVITY OF CLASS II

The presented paper is focused on the stress – strain analysis of the restored tooth. For this problem computational modelling was chosen using the finite element method. The tooth is modelled from dentin and dental enamel with a class II cavity. The size of the dental cavity is considered in three sizes and three shapes. For restoration two types of filling materials were used. A physiological model of the tooth was created as well. Force was prescribed on the occlusal surface of the tooth. The analysis of results shows that from the different filling materials, and their interaction with the dental tissues, amalgam is from a mechanical aspect the best material for the restored tooth in the molar segment.
Physiological, environmental, and hormonal factors at insemination which may affect conception.

Abstract Rectal and uterine temperatures of lactating dairy cows were recorded at insemination and 14.5 ± 4.6 h (mean ± standard deviation) later for the first three services. Blood samples were collected from a subcutaneous abdominal vein at the later time. Plasma corticoids and progesterone were quantified by competitive protein-binding analysis. Climatological data were obtained throughout the experiment from September through August. Means and standard deviations of 226 rectal and uterine temperatures at insemination were 38.4 ± . 04 C and 38.6 ± . 03 C and later, 38.1 ± . 03 C and 38.3 ± . 03 C. Mean corticoid and progesterone (ng/ml) at the later time were 8.02 ± . 32 and . 28 ± . 06. Uterine temperature at insemination; maximum, minimum, and average temperature the day of insemination; and maximum, minimum, and average temperature the day after insemination were associated with variation in conception. Uterine temperatures and average ambient temperature on day of insemination were inversely related to fertility. Progesterone at the later time was related to environmental temperatures on day of insemination. Plasma concentrations of progesterone and corticoids, sampled at the later time postinsemination, had no detectable association with conception.
Simple and robust PLL algorithm for accurate phase tracking under grid disturbances

Phase-locked loops (PLLs) are commonly used for the synchronization of grid connected power converters. However, the standard PLL structures are not able to reject grid disturbances such as voltage harmonics, unbalances or DC components in the measured voltage. Since the response of the power converters depends on the grid phase tracking, it is necessary to ensure an accurate synchronization even under distorted conditions. This paper proposes an enhanced PLL structure, which is able to perform fast synchronization even under weak grid conditions and frequency variations. Due to its low computational burden, the proposed PLL allows its implementation on low cost microprocessors.
