Optimal pricing strategy for wireless social community networks

Wireless social community operators rely on subscribers who constitute a community of users. The pricing strategy of the provided wireless access is an open problem for this new generation of wireless access providers. In this paper, using both analytical and simulation approaches, we study the problem comprised of modeling user subscription and mobility behavior and of coverage evolution with the objective of finding optimal subscription fees. We compute optimal prices with both static and semi-dynamic pricing. Coping with an incomplete knowledge about users, we calculate the best static price and prove that optimal fair pricing is the optimal semi-dynamic pricing. Moreover, we have developed a simulator to verify optimal prices of social community operators with complete and incomplete knowledge. Our results show that the optimal fair pricing strategy significantly improves the cumulative payoff of social community operators.
Effects of Zinc Deficiencyon Cellular Processesand Morphologyin Ehrlich Ascites Tumor Cells1

MATERIALS AND METHODS Some biochemicaland morphologicaleffects of host zinc deficiency upon Ehrlich cells have been observed and investi gated. The incorporation of [3H]thymidine into DNA of cells from normal and zinc-deficient hosts correlates with the zinc concentration in the ascitic fluid, with incorporation into DNA of zinc-deficient cells considerably depressed compared to cells from animals with adequate dietary zinc intake. Both the uptake of [3Hjthymidine into cells and its subsequent degree of incorporation into DNA are depressed in zinc-deficient tumors. The degree of inhibition correlates with the concentration of zinc in the ascites fluid. In contrast, the incorporation of [3H}. uridine into RNA is much less aftected by zinc-deficient con ditions and, in particular, uptake kinetics are hardly influenced. Furthermore, the kinetics of uptake and incorporation of thy midine into DNA at various fluid zinc concentrations are con sistent with the tumor cell population containing nondividing and normal cycling cells. Cells from zinc-deficient animals respire much more rapidly than do those from normal animals. Other parameters of mitochondrial integrity and regulatory coupling between glycolysis and oxidative phosphorylation are unaffected. A direct control of oxidative phosphorylation by zinc may be involved here. However, electron micrographic analyses of cells from normal and deficient animals show that in severe zinc insufficiency cells show morphological changes consistent with a loss in plasma membrane integrity. Such effects could also cause increased cell respiration. thiosemicarbazone inhibits DNA synthesis of Ehrlich cells in a metal-free medium. It chebatescopper and iron extremely well, and these complexes separately inhibit incorporation of thy midine into DNA (2). @In fact, o-phenanthroline and EDTAdiffer in the kinetics of inhibition of DNA synthesis in phytohemagglu tinin-stimulated lymphocytes and in the presumed molecular basisof the zinc effects(48).
Skew constacyclic codes over finite chain rings

Skew polynomial rings over finite fields ([7] and [10]) and over Galois rings ([8]) have been used to study codes. In this paper, we extend this concept to finite chain rings. Properties of skew constacyclic codes generated by monic right divisors of $x^n-\lambda$, where $\lambda$ is a unit element, are exhibited. When $\lambda^2=1$, the generators of Euclidean and Hermitian dual codes of such codes are determined together with necessary and sufficient conditions for them to be Euclidean and Hermitian self-dual. Of more interest are codes over the ring $\mathbb{F}_{p^m}+u\mathbb{F}_{p^m}$. The structure of all skew constacyclic codes is completely determined. This allows us to express generators of Euclidean and Hermitian dual codes of skew cyclic and skew negacyclic codes in terms of the generators of the original codes. An illustration of all skew cyclic codes of length~2 over $\mathbb{F}_{3}+u\mathbb{F}_{3}$ and their Euclidean and Hermitian dual codes is also provided.
Assessing the Vulnerability of Yucca Mountain Shipments : A Threat Matrix for Human-Initiated Events-8152

In preparation for review of two Department of Energy (DOE) National Environmental Policy Act (NEPA) documents, the Draft Supplemental Environmental Impact Statement for Yucca Mountain (DSEIS) and the Draft Rail Alignment Environmental Impact Statement (RA DEIS), the State of Nevada sponsored a study of vulnerability methodologies which could be applied to Yucca Mountain shipments. This study examined various human-initiated events, including sabotage, terrorism, induced accidents, and protest demonstrations. This paper reports the findings of that study, and recommends a comprehensive threat assessment methodology for use in evaluating sabotage and terrorism events, pursuant to a resolution adopted by the Western Governors Association (WGA) in 2007. The WGA 07-2 Resolution called on the Nuclear Regulatory Commission (NRC) and DOE to “fuly address the consequences of atacks against al components of the nuclear waste handling and transport system. ”
The association between parent-child relationship and child loneliness

Relatively little research has been conducted to examine the role of parent-child relationships in understanding loneliness during middle childhood. In the current study, twelve second to fourth grade children attending several elementary schools in a large western urban district were asked to complete the Loneliness and Social Dissatisfaction Questionnaire (LSDQ, Asher, Hymel & Renshaw, 1984) and the Parent-child Relationship Questionnaire (PCRQ, Furman & Giberson, 1995). The parents of all child participants were also invited to complete the same questionnaires. A sample of eight children, four who reported highest scores and four who reported lowest scores on the LSDQ, participated in follow-up qualitative interviews which inquired children’s friendships, relationships with parents, attitudes toward school, and preferred coping strategies with loneliness experiences. It was found that there was a significant positive correlation between the child-reported and the parent-reported child loneliness scores, suggesting that parents were accurately aware of their children’s loneliness levels. It was also found that the child-reported parent-child relationship and child loneliness were significantly and negatively correlated, meaning that the lower level of child-reported parent-child relationship quality, the higher level of child-reported child loneliness. Additionally, the qualitative data suggested that children with different levels of loneliness coped differently. They also seemed to hold different beliefs and expectations iii regarding their friendships, parent-child relationships, and attachments with school. Increasing our understanding of child loneliness will enable school and mental health professionals to develop more effective strategies to support children who are feeling extremely lonely and who may lack of home support. Identifying these at-risk children early and intervening with intensive individual plans through home-school collaboration may prevent poor long term academic and social-emotional outcomes.
Watchdog Designs for TinyOS Motes

We investigate a way to increase the reliability of distributed wireless networks by introducing two watchdog designs on the Mica mote. These watchdogs detect errors through monitoring aspects of the system and then take steps so that the mote recovers from these errors. The first design is a coprocessor watchdog that monitors the functionality of the main processor through heartbeat signals. The second watchdog design is a buddy system consisting of three motes that monitors each other’s radio functionality through heartbeat packets. From these watchdog designs, we analyze the scenarios where they are able to detect errors and recover. We also estimate the costs of memory usage, CPU utilization, and power consumption to implement these watchdogs and show that these costs are small percentages of the overall available resources. We conclude that the distributed wireless network would benefit from these watchdogs by the additional error detection and recovery that was not previously available. We find that the benefits of increased overall system reliability greatly outweigh the costs.
Risk-Sensitive Particle Filters for Mitigating Sample Impoverishment

Risk-sensitive filters (RSF) put a penalty to higher-order moments of the estimation error compared to conventional filters as the Kalman filter minimizing the mean square error (MSE). The result is a more cautious filter, which can be interpreted as an implicit and automatic way to increase the state noise covariance. On the other hand, the process of jittering, or roughening, is well known in particle filters to mitigate sample impoverishment. The purpose of this contribution is to introduce risk-sensitive particle filters (RSPF) as an alternative approach to mitigate sample impoverishment based on constructing explicit risk functions from a general class of factorizable functions. It is first shown that RSF can be done in nonlinear systems using a recursion of an infinite dimensional information state which involves general risk functions. Then, this information state calculation is carried out using particle approximations. Some alternative approaches, generalizations, specific cases, comparison to existing methods of sample impoverishment mitigation and issues related to the selection of risk functions and parameters are examined. Performance of the resulting filter using various risk functions is illustrated on a simulated scenario and compared with the roughening method.
Towards a simulation driven stereo vision system

This paper presents a novel algorithm for estimating stereo disparity which exploits the benefit of learning to the fullest. Given a cost volume of stereo matching, we solve the cost aggregation and disparity computation in one shot by using a classifier; we design a feature called matching cost pattern for the input which we extract from the cost volume while we use simulated stereo patterns for training. To this end, we introduce a highly realistic computer graphics dataset, the new Tsukuba stereo dataset, with ground-truth disparity maps. Through preliminary experiments we show that our algorithm outperforms a simplified AD-Census cost-minimization method, and also that the error ratio decreases as we use a larger number of samples for training.
Measuring Attitude of Rural Youth towards Dairying as an Occupation: A Likert Scale

There are two important ways of thinking on the issue of rural youth vis-a-vis farming: Farming as the saviour of rural youth, or rural youth as the saviour of farming. Whatever may be the situation, one thing is quite evident that rural youth and farming are interrelated with each other. According to the latest Census of India (2011), the total population of India is 1.21 billion and 66 per cent of population is up to 35 years of age. Even if 18 to 35 years of age category is considered, 36 per cent population would be covered in it. Demographical distribution of India is very much skewed towards lower age. According to the latest survey of National Sample Survey Organization (2013), 64.1 per cent of rural people are engaged in the agricultural sector. In rural areas, especially among marginal and small farmers, dairying provides a supplementary income opportunity, and many a time, it may be only livelihood option for landless peasants. Livestock sector specifically dairying provides livelihood security. But migratory intention of rural youth towards urban area, had made the basic tenet of studying attitude International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 12 (2017) pp. 3173-3181 Journal homepage: http://www.ijcmas. com
Secrecy versus patenting

Conflicting research exists regarding patents andintellectual property rights (IPRs). To clarify previous research, thisstudy examines how the patent system and inventor secrecy impact uponinnovation, information spreading, and welfare.A literature reviewregarding the aforementioned factors is provided. Then, the equilibrium search model of innovation is presented, consideringsuch factors as the timing of events, the steady state stocks of innovations,and revenue and consumer surplus.The impact on equilibrium of an industrythat is deficient in IPRs and patents is assessed and several lemmas areproposed. The welfare of an economy that lacks patents is alsoevaluated. The effect of both patenting and secrecy on the equilibrium level isinvestigated according to the model, and the incentives to innovate areconsidered.Finally, the welfare effect of an economy that promotespatents and patent policy is explored. The findings indicate that an effective patent system, where innovatorspatent their inventions, can result in the stimulation of innovation andinformation disclosure, resulting in improved welfare.Further, theprotection level of optimal patents versus secrecy is contradictory, with lessprotection often being the result.This indicates that an optimal patent'spurpose is to spread information rather than rewarding the expenditures ofinnovation.

On the Benefits of Planning and Grouping Software Maintenance Requests

Despite its unquestionable importance, software maintenance usually has a negative image among software developers and even project managers. As a result, it is common to consider maintenance requests as short-term tasks that should be implemented as quick as possible to have a minimal impact for end-users. In order to promote software maintenance to a first-class software development activity, we first define in this paper a light weighted process -- called PASM (Process for Arranging Software Maintenance Requests) -- for handling maintenance as software projects. Next, we describe an in-depth evaluation of the benefits achieved by the PASM process at a real software development organization. For this purpose, we rely on a set of clustering analysis techniques in order to better understand and compare the requests handled before and after the adoption of the proposed process. Our results indicate that the number of projects created to handle maintenance requests has increased almost three times after this organization has adopted the PASM process. Furthermore, we also concluded that projects based on the PASM present a better balance between the various software engineering activities. For example, after adopting PASM the developers have dedicated more time to analysis and validation and less time to implementation and codification tasks.
Plasticity Kernels and Temporal Statistics

Computational mysteries surround the kernels relating the magnitude and sign of changes in efficacy as a function of the time difference between pre- and post-synaptic activity at a synapse. One important idea34 is that kernels result from filtering, ie an attempt by synapses to eliminate noise corrupting learning. This idea has hitherto been applied to trace learning rules; we apply it to experimentally-defined kernels, using it to reverse-engineer assumed signal statistics. We also extend it to consider the additional goal for filtering of weighting learning according to statistical surprise, as in the Z-score transform. This provides a fresh view of observed kernels and can lead to different, and more natural, signal statistics.
Food Price Policies and the Distribution of Body Mass Index: Theory and Empirical Evidence from France

This paper uses French food-expenditure data to examine the effect of the local prices of 23 food product categories on the distribution of Body Mass Index (BMI) in a sample of French adults. A dynamic choice model using standard assumptions in Physiology is developed. It is shown that the slope of the price-BMI relationship is affected by the individual's Physical Activity Level (PAL). When the latter is unobserved, identi cation of price effects at conditional quantiles of the BMI distribution requires quantile independence between PAL and the covariates, especially income. Using quantile regressions, unconditional BMI distributions can then be simulated for various price policies. In the preferred scenario, increasing the price of soft drinks, breaded proteins, deserts and pastries, snacks and ready-meals by 10%, and reducing the price of fruit and vegetables in brine by 10% would decrease the prevalence of overweight and obesity by 24% and 33% respectively. The fall in health care expenditures would represente up to 1.39% of total health care spendings in 2004.
Aberrant Collagen Composition of the Trabecular Meshwork Results in Reduced Aqueous Humor Drainage and Elevated IOP in MMP-9 Null Mice

Purpose Homeostatic turnover of the trabecular meshwork extracellular matrix (ECM) is essential to regulate aqueous humor outflow and to maintain intraocular pressure homeostasis. In this study, we evaluated aqueous humor turnover, intraocular pressure, and trabecular meshwork organization in MMP-9 null mice. Methods Intraocular pressure and aqueous humor turnover were measured in MMP-9 null versus wild-type mice. Morphology of the anterior segment of the eye, with special attention to the structural organization of the trabecular meshwork, was investigated by means of optical coherence tomography, light microscopy, and transmission electron microscopy. Furthermore, using quantitative real-time polymerase chain reaction and immunostainings, we evaluated the ECM composition of the trabecular meshwork. Finally, the integrity and function of the retina and optic nerve were assessed, via optical coherence tomography, histologic techniques, and optomotor testing. Results MMP-9 null mice displayed early-onset ocular hypertension and reduced aqueous humor turnover. While transmission electron microscopic analysis did not reveal any abnormalities in the cellular organization of the trabecular meshwork, detailed investigation of collagen expression indicated that there is an aberrant trabecular meshwork ECM composition in MMP-9 null mice. Notably, at the age of 13 months, no glaucomatous neurodegeneration was seen in MMP-9 null mice. Conclusions Our observations corroborate MMP-9 as an important remodeler of the collagenous composition of the trabecular meshwork and provide evidence for a causal link between MMP-9 deficiency, trabecular meshwork ultrastructure, and ocular hypertension.
A novel H395R mutation in MKKS/BBS6 causes retinitis pigmentosa and polydactyly without other findings of Bardet-Biedl or McKusick-Kaufman syndrome

Purpose To identify the causative mutation in two siblings from a consanguineous family in India with retinitis pigmentosa (RP) and polydactyly without other findings of Bardet-Biedl syndrome (BBS). We also performed functional characterization of the mutant protein to explore its role in this limited form of BBS. Methods The siblings underwent a thorough ophthalmological examination, including retinal optical coherence tomography (OCT) imaging, and an extensive physical examination with abdominal ultrasonography to characterize the disease phenotype. Next-generation sequencing (NGS) using a panel targeting retinal degeneration genes was performed on genomic DNA samples from the siblings and parents. Upon identification of the causative mutation, functional characterization was accomplished by performing protein–protein interaction studies in human embryonic kidney (HEK-293T) and human adult retinal pigmented epithelium (ARPE-19) cells. Results The two siblings showed signs of RP and polydactyly. The patients did not have truncal obesity, renal anomalies, hydrometrocolpos, congenital heart disease, or overt cognitive defects. NGS identified a homozygous c.1184A>G mutation in the MKKS/BBS6 gene in both patients resulting in a p.H395R substitution in the MKKS/BBS6 protein. This mutant protein decreased the interaction of MKKS/BBS6 with BBS12 but did so to a different extent in the HEK-293T versus ARPE-19 cells. Nonetheless, the effect of the H395R variant on disrupting interactions with BBS12 was not as profound as other reported MKKS/BBS6 mutations associated with syndromic RP. Conclusions We identified a novel H395R substitution in MKKS/BBS6 that results in a unique phenotype of only RP and polydactyly. Our observations reaffirm the notion that mutations in MKKS/BBS6 cause phenotypic heterogeneity and do not always result in classic MKKS or BBS findings.
Support Structures for Women in Information Technology Careers

This paper examines issues of support for women with Information Technology (IT) careers. Interviews of 38 women with careers in information technology sectors of different industries lasted about 90 minutes and consisted of open-ended questions regarding aspects of their careers and career paths. Research on the lack of women in STEM disciplines focuses mainly on undergraduate education and attracting women to STEM disciplines, focusing on ‘filling the pipeline. ’ This research seeks to understand what it takes to have a successful, satisfying career, especially areas of support for women that may influence their success in IT careers. Knowing this may give women help in planning their careers and navigating a male dominated industry.
The impact of dipole straylight contamination on the alignment of low multipoles of CMB anisotropies

We estimate the impact of the dipole straylight contamination (DSC) for the Planck satellite on the alignments of vectors associated with the low multipoles of the pattern of the cosmic microwave background (CMB) anisotropies. In particular we study how the probability distributions of 18 estimators for the alignments change when DSC is taken into account. We find that possible residual DSC should leave a non-negligible impact on low multipole alignments for effective values of the fractional far sidelobe integrated response, p, larger than ∼ few × 10 −3 . The effect is strongly dependent on the intrinsic sky amplitude and weakly dependent on the considered scanning strategy. We find a decrease of the alignment probability between the quadrupole and the dipole and an increase of the alignment probability between the hexadecapole and the dipole (larger is the intrinsic sky amplitude and lower is the contamination). The remaining estimators do not exhibit clear signatures, except, in some cases, considering the largest values of p and the lowest sky amplitudes. Provided that the real sidelobes of the Planck receivers in flight conditions will correspond to p few × 10 −3 , as realistically expected at least in the cosmological frequency channels, and will be known with accuracies better than ∼ few × 10 per cent allowing for a suitable cleaning during data reduction, Planck will be very weakly affected from DSC on the alignments of low multipoles.
Designing Fair Tiebreak Mechanisms: The Case of FIFA Penalty Shootouts

In the current FIFA penalty shootout mechanism, a coin toss decides which team will kick first. Empirical evidence suggests that the team taking the first kick has a higher probability to win a shootout. We design sequentially fair shootout mechanisms such that in all symmetric Markov-perfect equilibria each of the skill-balanced teams has exactly 50% chance to win whenever the score is tied at any round. Consistent with empirical evidence, we show that the current mechanism is not sequentially fair and characterize all sequentially fair mechanisms. Taking additional desirable properties into consideration, we propose and uniquely characterize a practical mechanism.
