Enabling vehicular safety applications over LTE networks

Advanced Driving Assistance Systems (ADAS) for improving vehicular safety are increasingly network based, with approaches that use vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communication. Most current proposals for V2V and V2I use DSRC and a dedicated infrastructure of road side units (RSUs) for the V2I scenarios. Here, the technical feasibility of an alternative architecture is explored, one that uses a combination of LTE cellular networks and servers near the edge of the LTE network. Compared with approaches based on DSRC and RSUs, this architecture exploits an infrastructure that is already largely deployed, but requires that technical challenges related to latency and scalability be addressed. This paper outlines an architecture that addresses these challenges and shows experimental results that demonstrate its effectiveness for vehicular safety applications. The approach combines resources near the network edge with broadcast-based data distribution to provide data freshness guarantees comparable to what can be achieved with DSRC for many applications. Experiments from the deployed LTE network and NS-3 simulations demonstrate that this approach is feasible, and show the benefits and limitations of the architecture.
The cloacin receptor of ColV-bearing Escherichia coli is part of the Fe3+-aerobactin transport system

Escherichia coli strains which contain the Fe3+-aerobactin transport system specified by the ColV plasmid became deficient in aerobactin-dependent iron transport when they were converted to cloacin-resistant derivatives. An outer membrane protein with a molecular mass of 74,000 daltons was overproduced under iron-limiting growth conditions and was absent in cloacin-resistant mutants. Fe3+-aerobactin protected cells against cloacin. These results suggest that the cloacin receptor protein, controlled by the colV plasmid, also participates in Fe3+-aerobactin transport.
Estradiol receptor content in rat granulosa cells during follicular development: modification by estradiol and gonadotropins.

To examine the relationships between gonadotropic hormones, ovarian follicular development, and estradiol receptor content in rat granulosa cells, follicular growth was stimulated in intact immature rats and hypophysectomized immature rats. In intact rats, both PMSG and oFSH given for 2 days stimulated follicular growth and endogenous estrogen production but caused estradiol receptor content in granulosa cells to decrease markedly. In hypophysectomized rats estradiol (2 mg/day X 4) was capable of increasing the content of its own receptor, stimulated preantral follicular development, and potentiated the responses of granulosa cells to highly purified hFSH. Thus, subsequent treatment with hFSH stimulated antral formation and maintained high levels of estradiol receptor content in granulosa cells. LH, on the other hand, caused a rapid decline in the content of estradiol receptor in nuclei of granulosa cells. In hypophysectomized rats primed with estradiol alone, a high dose of oLH caused follicles to undergo atresia. In hypophysectomized rats primed with hFSH in addition to estradiol, oLH stimulated luteinization. Thus, induction of atresia or luteinization by oLH in these rats appears to be associated (cause or effect? ) with a loss of estradiol receptor in granulosa cells. Whether follicles of estrogen-treated, hypophysectomized rats luteinize or undergo atresia in response to LH appears to be determined by their stage of differentiation and the nature of the prior stimulation by FSH.
The pathogenesis of bacterial keratitis: studies with Pseudomonas aeruginosa

Bacterial keratitis is a sight‐threatening corneal disease that is most commonly associated with the extended wear of soft contact lenses. Over the past decade, we have investigated the pathogenesis of infectious keratitis involving the opportunistic pathogen Pseudomonas aeruginosa. Our research has focused on understanding the respective roles of bacteria and host in the establishment of this infection. Here, we provide a current perspective on P. aeruginosa keratitis, reviewing some of the research developments that have helped shape our views on the mechanisms by which pathogen and host response cause corneal disease. P. aeruginosa may provide a model for the pathogenesis of bacterial keratitis and help further elucidate the complex array of host factors that normally protect the cornea from infectious agents.
Gene expression pattern Characterization of a subfamily of related winged helix genes, XFD-12/ 12 0 /12 00 (XFLIP), during Xenopus embryogenesis

The fork head domain family of genes defines a growing group of proteins that serve important regulatory functions in pattern-forming events of both invertebrates and vertebrates. Here we add three closely related, novel members to this family in Xenopus laevis, termed XFD12, XFD-12 0 and XFD-12 00 . All three genes reveal indistinguishable expression patterns during Xenopus embryogenesis. During gastrulation, XFD-12 type transcripts are detected exclusively in the superficial layer of cells within the Spemann organizer territory. In the open neural plate, XFD-12 type expression defines a row of cells located along the dorsal midline and destined to become the floor plate of the neural tube. After closure of the neural tube, XFD-12 type encoding mRNAs are only detected in the tailtip and a small area located at the midbrain/ hindbrain boundary. Within the Spemann organizer and in the floor plate area, expression of XFD-12 type genes is only partially overlapping with XFD-1 expression. q 1999 Elsevier Science Ireland Ltd.

User interface patterns for hypermedia applications

Designing high quality visual interfaces for hypermedia applications is difficult; it involves organizing different kinds of interface objects (for example those triggering navigation), prevent lhe user from cognitive overhead, etc. Unfortunately, interface design methods do not capture design decisions or rationale, so it is hard to record and convey interface design expertise. In this paper, we introduce interface patterns for hypermedia applications as a concept for reusing interface designs. The structure of this paper is as follows: first, we introduce the context in which these patterns were discovered and we give a rationale for their use. Then we present some simple but effective patterns using a standard template. We finally discuss some further issues on the use of interface patterns in hypermedia applications.
Encapsulation and Composition of Ontologies

Ontology concerns itself with the representation of the objects in the universe and the web of their various connections. The traditional task of ontologists has been to extract from this tangle a single ordered structure, in the form of a tree or lattice. This structure consists of the terms that represent the objects, and the relationships that represent connections between objects. Recent work in ontology goes so far as to consider several distinct, superimposed structures, which each represent a classification of the universe according to a particular criterion. Our purpose is to defer the task of globally classifying terms and relationships. Instead, we focus on composing them for use as we need them. We define contexts to be our unit of encapsulation for ontologies, and use a rule-based algebra to compose novel ontological structures within them. We separate context from concept, the unit of ontological abstraction. Also, we distinguish composition from subsumption, or containment, the relationships which commonly provide structure to ontologies. Adding a formal notion of encapsulation and composition to ontologies leads to more dynamic and maintainable structures, and, we believe, greater computational efficiency for knowledge bases.
Flavobacterium johnsoniae GldJ Is a Lipoprotein That Is Required for Gliding Motility

ABSTRACT Cells of Flavobacterium johnsoniae glide rapidly over surfaces by an unknown mechanism. Eight genes required for gliding motility have been described. Complementation of the nonmotile mutant UW102-48 identified another gene, gldJ, that is required for gliding. gldJ mutants formed nonspreading colonies, and individual cells were completely nonmotile. Like previously described nonmotile mutants, gldJ mutants were deficient in chitin utilization and were resistant to bacteriophages that infect wild-type cells. Cell fractionation and labeling studies with [3H]palmitate indicated that GldJ is a lipoprotein. Mutations in gldA, gldB, gldD, gldF, gldG, gldH, or gldI resulted in normal levels of gldJ transcript but decreased levels of GldJ protein. Expression of truncated GldJ protein in wild-type cells resulted in a severe motility defect. GldJ was found in regular bands that suggest the presence of a helical structure within the cell envelope.
Deforestation reduces nest mound size and decreases the production of sexual offspring in the wood ant Formica aquilonia

Sorvari, J. & Hakkarainen, H. 2005: Deforestation reduces nest mound size and decreases the production of sexual offspring in the wood ant Formica aquilonia. — Ann. Zool. Fennici 42: 259–267. Little is known about how anthropogenic changes in nature affect reproduction in social insects such as ants. We studied the effects of clear-cutting on the production of sexual offspring and on the mound size in Formica aquilonia, using neighbouring uncut forests as controls. Nest mounds were smaller in clear-cuts, apparently because they tended to be new bud nests. The basal area of nest mounds decreased towards forest edges. The production of sexual offspring increased with nest mound size. Clear-cutting reduced the production of sexual offspring also when the effect of nest mound size had been factored out. Our results show that anthropogenic changes do have the potential to modify the production of sexual offspring in social insect.
The Imperial Signifier: Todorov and the Conquest of Mexico

[The Aztecs] . lacked the use of letters, a notable deficiency. They used neither money nor weights. They did not know how to make ships with sails, tackle, rigging, and cordage and know how to sail them . They lacked iron and the weapons and tools which are made from it; they also lacked wheat and mills with which to grind their maize, the grain they eat. They had no olive oil or wine, although the earth produced both olives and grapes naturally . They did not know how to make candles from wax and tallow for lighting. They had no beasts of burden for riding or for drawing carts or litters. They sacrificed war prisoners and slaves in such great numbers that in Mexico city alone they are believed to have sacrificed more than twenty thousand persons each year, and they ate their flesh without repugnance. -Juan de Mariana, 15901
Predicting identification errors in a multibiometric system based on ranks and scores

The goal of a biometric identification system is to determine the identity of the input biometric data. In such a system, the input probe (e.g., a face image) is compared against the labeled gallery data (e.g., face images in a watch-list) resulting in a set of ranked scores pertaining to the different identities in the gallery database. The identity corresponding to the best score is then associated with that of the probe. The aim of this work is to predict identification errors and improve the recognition accuracy of the biométrie system. The method utilizes the rank and score information generated by the identification operation in order to validate the output. Further, we demonstrate the proposed predictor can be effectively applied in multimodal scenarios. Experiments performed on two multimodal databases show the effectiveness of our framework in improving identification performance of biométrie systems.
Prevalence of risk factors for non-communicable diseases in rural & urban Tamil Nadu

Background & objectives: Surveillance of risk factors is important to plan suitable control measures for non-communicable diseases (NCDs). The objective of this study was to assess the behavioural, physical and biochemical risk factors for NCDs in Vellore Corporation and Kaniyambadi, a rural block in Vellore district, Tamil Nadu, India. Methods: This cross-sectional study was carried out among 6196 adults aged 30-64 yr, with 3799 participants from rural and 2397 from urban areas. The World Health Organization-STEPS method was used to record behavioural risk factors, anthropometry, blood pressure, fasting blood glucose and lipid profile. Multiple logistic regression was used to assess associations between risk factors. Results: The proportion of tobacco users (current smoking or daily use of smokeless tobacco) was 23 per cent in the rural sample and 18 per cent in the urban, with rates of smoking being similar. Ever consumption of alcohol was 62 per cent among rural men and 42 per cent among urban men. Low physical activity was seen among 63 per cent of the urban and 43 per cent of the rural sample. Consumption of fruits and vegetables was equally poor in both. In the urban sample, 54 per cent were overweight, 29 per cent had hypertension and 24 per cent diabetes as compared to 31, 17 and 11 per cent, respectively, in the rural sample. Physical inactivity was associated with hypertension, body mass index (BMI) ≥25 kg/m2, central obesity and dyslipidaemia after adjusting for other factors. Increasing age, male sex, BMI ≥25 kg/m2 and central obesity were independently associated with both hypertension and diabetes. Interpretation & conclusions: Diabetes, hypertension, dyslipidaemia, physical inactivity and overweight were higher in the urban area as compared to the rural area which had higher rates of smokeless tobacco use and alcohol consumption. Smoking and inadequate consumption of fruits and vegetables were equally prevalent in both the urban and rural samples. There is an urgent need to address behavioural risk factors such as smoking, alcohol consumption, physical inactivity and inadequate intake of fruits and vegetables through primary prevention.
World Development Report 2015: Programming the Poor

The World Bank has discovered that people are programmable, and some (poor people) are more programmable than others. So the 2015 World Development Report (Mind, Society and Behavior) has ditched the ‘rational actor’ model on which neo-classical economics was built, as an impediment to the purposive transformation of society. It draws on a wide range of disciplines (behavioural economics, cognitive science, psychology, neuroscience) to ‘improve the design and implementation of development policies that target human choices and action,’ or in other words to turn our own cognitive capacity and sociality against us with the transparent objective of implanting the whole of humanity with the gene of conformity in thought and behaviour to the logic of globally competitive capitalism.
Supported liquid extraction offers improved sample preparation for aldosterone analysis by liquid chromatography tandem mass spectrometry

Background To evaluate the accuracy and precision of a method for serum aldosterone using supported liquid extraction (SLE) for sample preparation instead of the more conventional liquid-liquid extraction (LLE) approach. Methods Two independently developed SLE-based LC-MS/MS methods for serum aldosterone (sample volumes 250 μl and 300 μl respectively) were compared to a modification of a previously reported LLE approach (sample volume 500 μl) in two method comparisons (n=75 and n=97). SLE analyses were performed at two separate centres. Precision was evaluated at a single site using human pools in head-to-head comparison between SLE and LLE. All analyses were performed on the ABSCIEX API-5000 LC-MS/MS system. Results At four increasing pool concentrations spanning 67-1060 pmol/l, total precision for SLE ranged from 6.8-4.1% compared with 11.1-4.3% for LLE. Differences did not reach statistical significance except at the lowest concentration where SLE was superior. Pasing Bablok regression comparisons were SLE=0.96×LLE-5.8 pmol/l (R2=0.985) and SLE=0.96×LLE-0.44 pmol/l (R2=0.969). Conclusions For analysis of serum aldosterone on the ABSCIEX API-5000, SLE affords a smaller sample volume while maintaining the accuracy and precision performance of LLE. By avoiding specimen vortexing, SLE also allows for greater automation in the sample preparation.
Otolith End Organ Projections to Auditory Neurons in the Descending Octaval Nucleus of the Goldfish, Carassius auratus: A Confocal Analysis

The distribution of axons from the saccule, lagena, and utricle to descending octaval nucleus neurons that project to the auditory midbrain in the goldfish is reported. We have divided these auditory projection neurons, located in the dorsal portion of the descending octaval nucleus (dDO), into two groups, medial and lateral, each of which contains several neuronal populations based on morphology and location. At most levels of the dDO, there are three medial and three lateral populations; the rostral dDO contains an additional lateral population. The saccule provides input to each of the seven medial and lateral populations but appears to be the exclusive/nearly exclusive source of primary input to the most dorsal cell group of the medial population. Along with the saccule, the lagena and utricle each supply the remaining six medial and lateral populations. Neurons in each of these populations receive input from more than one end organ. One medial and one lateral population include neurons that receive remarkably large contacts from utricular afferents. Overall, the results reveal a more substantial input from the lagena and utricle to the main first-order auditory nucleus in the goldfish than was previously recognized, suggest this nucleus is composed of functionally distinct populations, and relate to functional and evolutionary issues about hearing in early vertebrates.
Harmonic instability source identification in large wind farms

A large-scale power electronics based power system like a wind farm introduces the passive and active impedances. The interactions between the active and passive impedances can lead to harmonic-frequency oscillations above the fundamental frequency, which can be called harmonic instability. This paper presents an approach to identify which wind turbine and which bus has more contribution to the harmonic instability problems. In the approach, a wind farm is modeled as a Multi-Input Multi-Output (MIMO) dynamic system. The poles of the MIMO transfer matrix are used to predict the system instability and the eigenvalues sensitivity analysis in respect to the elements of the MIMO matrix locates the most influencing buses of the wind farm. Time-domain simulations in PSCAD software environment for a 400-MW wind farm validate that the presented approach is an effective tool to determine the main source of the instability problems.
Simulation of Statistical Variability in Nano MOSFETs

Using 3D statistical numerical simulations we study and compare the impact of various sources of statistical variability in nano-CMOS transistors including random discrete dopants (RDD), line edge roughness (LER), polysilicon granularity (PSG) and interface roughness (IR). We show that the random dopant induced parameter fluctuations in conventional MOSFETs become a showstopper, impacting already adversely on their integration in SRAMs, and may force early transition to UTB SOI and double gate device architectures.
A TOPOLOGY REPRESENTING NETWORK APPROACH TO MARKET PRICE MODELLING

This paper suggests a simple model of stock market, where artificial neural networks play the role of traders. Each net is assumed to take long/ short positions in the market, according to perception of future price fluctuations they have formed during a learning procedure over past data. Final price comes then out as meeting point among different nets positions. The novelty of this approach relies in the kind of neural architecture employed (topology representing networks), and in the way exogenous information are processed. Experimental results are then compared to real data, testing their consistency under financial and statistical profiles.
The influence of participation in a community mapping project on grade four students’ environmental worldviews

This study examined if and how participation in a community mapping project influenced grade four students’ environmental world views immediately after and three months after the culmination of the project. A mixe d methods approach was used as students completed pre-test, post-test, and followup New Ecological Paradigm for Children scales and participated in post-test and f ollow-up interviews. Students’ overall NEP scores were pro-environmental at each point in the study and the students’ scores on the Rights of Nature factor improved significantly from the pre-test to the follow-up. Students’ interview comments suggested improvements in environmental knowledge and attitude, understanding of humans’ environmental im pacts, and connection to place. The results of the study have implications for future r esearch and environmental education curriculum and instruction.
Knowledge, attitude and practice of emergency contraception on nursing personnel.

INTRODUCTION Emergency Contraception is a grossly underu-tilized option of prevention of pregnancy. It is a safe and effective method which can prevent unintended pregnancies, unsafe abortions and unwanted childbirth. Knowledge and attitude of Nursing personnel who are both service providers and health educators to the community can influence the contraceptive behavior of the people exposed to them. A few studies done in our country indicate that their awareness regarding EC is low. AIM To explore the knowledge, attitude and practice of EC amongst Nursing Personnel in a medical college hospital. MATERIALS AND METHODS In this study, 185 nursing personnel participated. A predesigned, pretested questionnaire was used to collect their responses regarding knowledge, attitude and practice of EC. Descriptive analysis of data was done. Results : Out of the total, 52.43% of the participants had good knowledge regarding the general information of EC, 51.35% had positive attitude towards EC, 47.56% had expressed willingness to use EC if indicated whereas only 22.7% had ever used EC. 72.97% had expressed willingness to attend awareness programmes on EC. Conclusion :Even though knowledge and attitude towards EC among the participants was marginally good they had many misconceptions regarding specific aspects like mode of action, indications and timing of administration. More awareness programmes would definitely clear their misconceptions and apprehensions and encourage Nursing Personnel to personally use and promote EC to others.
Vestibular Evoked Myogenic Potentials in Young Children: Test Parameters and Normative Data

Objective: The vestibular evoked myogenic potential (VEMP) is a test of the vestibulocollic reflex that has been extensively studied in adults. Much is known about the normal values in adults as well as their changes with age. In children, the expected test values and their possible changes in development have not yet been described nor has the feasibility of reliable testing in this group. The aim of this prospective study is to accumulate normative data and to verify the viability of testing in young children. The study focused on optimal test parameters, reproducibility, and subject compliance in a pediatric population.
