Anchoring Action Representation to Perception in a Mobile Robot

The framework proposed in [3, 5] for the representation of inner perceptual knowledge of a robot is generalized to include a representation of actions, in order that a mobile robot can exploit its inner perceptual representations to anchor its actions to perception. Such extension is aimed to allow the robot to simulate its own future actions, to anticipate their consequences and evaluate them in order to choose the most appropriate action to perform. The proposed framework is illustrated by describing its performances in a cat-mouse scenario.
Nanoengineering to Achieve High Sodium Storage: A Case Study of Carbon Coated Hierarchical Nanoporous TiO2 Microfibers

Nanoengineering of electrode materials can directly facilitate sodium ion accessibility and transport, thus enhancing electrochemical performance in sodium ion batteries. Here, highly sodium‐accessible carbon coated nanoporous TiO2 microfibers have been synthesised via the facile electrospinning technique which can deliver an enhanced capacity of ≈167 mAh g−1 after 450 cycles at current density of 50 mA g−1 and retain a capacity of ≈71 mAh g−1 at the high current rate of 1 A g−1. With the benefits of their porous structure, thin TiO2 inner walls, and the introduction of conductive carbon, the nanoporous TiO2/C microfibers exhibit high ion accessibility, fast Na ion transport, and fast electron transport, thereby leading to the excellent Na‐storage properties presented here. Nanostructuring is proven to be a fruitful strategy that can alleviate the reliance on materials' intrinsic nature; and the electrospinning technique is versatile and cost‐effective for the fabrication of such an effective nanoporous microfiber structure.

Aim: To determine the bacteriological properties of the surface water obtained from Uke River. Place and Duration of Study: This study was carried out in Uke Community, Karu LGA, Nasarawa state and the Department of Biological sciences, Bingham University, Karu, between March and April 2016. Materials and Methods: Water samples were collected randomly from five points at the Uke River for five weeks. The total heterotrophic bacteria count, fecal coliform count and total coliform count were used to determine bacterial contamination. Biochemical tests and gram reaction was used to identify the bacterial isolates. Results: Six bacterial genera which include Salmonella spp, Staphylococcus spp, Escherichia spp, Pseudomonas spp, Enterococcus spp and Klebsiella spp were isolated from the water samples. Escherichia coli had the highest frequency of 23(43%). The mean total heterotrophic count, total Original Research Article Ihuma et al.; AJOB, 1(1): 1-6, 2016; Article no.AJOB. 30518 2 coliform count and fecal coliform count were 2.3× 10, 2.4×10, and 2.6×10 respectively. Conclusion: The bacteriological analysis of the surface water indicates the presence of bacteria which suggests the water is not fit for consumption without proper processing.
Factors related to utilization of dental services by the elderly.

A household interview survey of 883 persons aged 62 and older residing in Seattle, Washington, asked about a broad range of health care and social service issues, including the need for and use of dental care. The Anderson model of health services utilization was used to identify predisposing, enabling, and need characteristics hypothesized to affect the use of dental services. A path analysis was conducted to distinguish the direct and indirect effects of the variables. The results showed that none of the predisposing variables, including age, was a significant factor in explaining the use of dental services. Education had both direct and indirect positive relationships to use. Having a regular sources of dental care was also an important factor affecting utilization. Neither income nor insurance variables were powerful factors. Need, measured by an index of dental problems and having dentures, was the stronger determinant of dental care use. In general, the model was better at predicting whether or not dental care would be sought by an older person at all (R2 = .27) than in predicting the amount of service used (R2 = .06).

Toward secure targeted broadcast in smart grid

Significant research efforts have recently been directed toward materializing smart grid for the purpose of transforming the aging power grid into an efficient and intelligent electric power distribution system. Conceptually, smart grid can be regarded as a fusion of different advanced technologies (i.e., electrical power engineering meets sensing, control, digital communication, and network information technologies). However, when these advanced technologies converge at smart grid, we will face many unforeseen challenges, particularly security challenges in smart grid communications. In this article, toward secure targeted broadcast in smart grid, we investigate the applicability of Attribute Based Encryption (ABE) for smart grid communication scenarios. In particular, we focus on the application of Key Policy ABE (KPABE), where a smart grid control center can use KP-ABE to broadcast a single encrypted message to a specific group of users, and each user in the targeted group can individually use the defined key policy to decrypt the message. With this kind of KP-ABE targeted broadcast, it is possible to eliminate the need for issuing multiple unicast messages. As a result, both communication and computation efficiency can be ensured.
Intraventricular migration of an isolated fourth ventricular cysticercus following cerebrospinal fluid shunting

Background: Isolated intraventricular neurocysticercosis (NCC) is less frequently seen and can be missed on plain magnetic resonance imaging (MRI). Three-dimensional constructive interference in steady state (CISS) sequence is an extremely helpful sequence in identifying the lesion but is rarely used routinely. Case Description: Here, we report a case of young male adult who presented with diminution of vision and headache. MRI of the brain revealed hydrocephalus, and on using CISS sequence only, the lesion could be identified in the fourth ventricle. He was treated with medical management, and ventriculoperitoneal shunting of cerebrospinal fluid was done to relieve the hydrocephalus. It resulted in immediate relief with aggravation of headache few days later. Repeat MRI revealed intraventricular migration into the left foramen of monro leading to left lateral ventricle dilatation necessitating endoscopic removal of the lesion. Conclusion: CISS sequence is definitely the sequence of choice in identifying intraventricular NCC. Ventriculoperitoneal shunting can result in the intraventricular migration of the cyst due to sudden decompression necessitating repeat surgery. Endoscopic removal of NCC has a high success rate with limited complications.
Successful outcome of therapy of acute hepatitis C following sexual and parenteral exposure – report of two cases

Acute hepatitis C (AHC) remains difficult to diagnose due to its asymptomatic course. The manuscript presents two children with AHC after known sexual and parenteral exposure, which allowed for close monitoring. Both developed increased aminotransferase activity, though the viral load was significantly higher after parenteral exposure. Lack of hepatitis C virus (HCV) clearance led to therapy with recombinant interferon-α with good toleration and response. The conclusion is that treatment of AHC was effective and well tolerated.
Phi Index: A New Metric to Test the Flush Early and Avoid the Rush Hypothesis

Optimal escape theory states that animals should counterbalance the costs and benefits of flight when escaping from a potential predator. However, in apparent contradiction with this well-established optimality model, birds and mammals generally initiate escape soon after beginning to monitor an approaching threat, a phenomena codified as the “Flush Early and Avoid the Rush” (FEAR) hypothesis. Typically, the FEAR hypothesis is tested using correlational statistics and is supported when there is a strong relationship between the distance at which an individual first responds behaviorally to an approaching predator (alert distance, AD), and its flight initiation distance (the distance at which it flees the approaching predator, FID). However, such correlational statistics are both inadequate to analyze relationships constrained by an envelope (such as that in the AD-FID relationship) and are sensitive to outliers with high leverage, which can lead one to erroneous conclusions. To overcome these statistical concerns we develop the phi index (Φ), a distribution-free metric to evaluate the goodness of fit of a 1∶1 relationship in a constraint envelope (the prediction of the FEAR hypothesis). Using both simulation and empirical data, we conclude that Φ is superior to traditional correlational analyses because it explicitly tests the FEAR prediction, is robust to outliers, and it controls for the disproportionate influence of observations from large predictor values (caused by the constrained envelope in AD-FID relationship). Importantly, by analyzing the empirical data we corroborate the strong effect that alertness has on flight as stated by the FEAR hypothesis.
Video Object Retrieval Based on Color Feature Modeling

Retrieve of the objects in the videos is a challenging and important work. Non-textual object information stored in videos is presented as grids of numbers in the image flames. Therefore, it is hard to retrieve the object in the videos with classical methods. In this paper, a robust color-feature model of the moving video objects is proposed by converting the RGB pixels to a color circle of hue. Furthermore, we give a framework of video object retrieval based on the color feature model. Finally, the experimental results indicate that the proposed model is accurate and similar to human recognition of the moving objects in videos view, which demonstrates the good performance of the color-feature model.
Thermodynamics of Asymptotically Locally AdS Spacetimes

We formulate the variational problem for AdS gravity with Dirichlet boundary conditions and demonstrate that the covariant counterterms are necessary to make the variational problem well-posed. The holographic charges associated with asymptotic symmetries are then rederived via Noether's theorem and `covariant phase space' techniques. This allows us to prove the first law of black hole mechanics for general asymptotically locally AdS black hole spacetimes. We illustrate our discussion by computing the conserved charges and verifying the first law for the four dimensional Kerr-Newman-AdS and the five dimensional Kerr-AdS black holes.
Specialization: Pro- and Anti-Globalizing, 1990-2002

Specialization alters the incidence of manufacturing trade costs to buyers and sellers, with pro-and anti-globalizing effects on 76 countries from 1990-2002. The structural gravity model yields measures of Constructed Home Bias (the ratio of predicted local trade to predicted frictionless local trade) and the Total Factor Productivity effect of changing incidence. A bit more than half the world's countries experience declining CHB and rising TFP. The effects are big for the outliers. A novel test of structural gravity provides striking confirmation, validating both the CHB and TFP measures that rely on it here, and the large gravity literature that relies on it elsewhere.

Quantifiers and approximation

Summary form only given. An investigation is made of the relationship between logical expressibility of NP optimization problems and their approximation properties. It is shown that many important optimization problems do not belong to MAX NP and that in fact there are problems in P which are not in MAX NP. The problems considered fit naturally in a new complexity class called MAX II/sub 1/. It is proved that several natural optimization problems are complete for MAX II/sub 1/ under approximation preserving reductions. All these complete problems are nonapproximable unless P=NP. This motivates the definition of subclasses of MAX II/sub 1/ that only contain problems which are presumably easier with respect to approximation. In particular, the class called RMAX(2) contains approximable problems and problems like MAX CLIQUE that are not known to be nonapproximable. It is proven that MAX CLIQUE and several other optimization problems are complete for RMAX(2). All the complete problems in RMAX(2) share the interesting property that they either are nonapproximable or are approximable to any degree of accuracy. <<ETX>>
Relative Stability of Wild-Type and Mutant p53 Core Domain: A Molecular Dynamic Study

The p53 protein is a stress response protein that functions primarily as a tetrameric transcription factor. A tumor suppressor p53 binds to a specific DNA sequence and transactivates target genes, leading to cell cycle apoptosis. Encoded by the human gene TP53, p53 is a stress response protein that functions primarily as a tetrameric transcription factor. This gene regulates a large number of genes in response to a variety of cellular functions, including oncogene activation and DNA damage. Mutations in p53 are common in human cancer types. Herein we mutate a wild-type p53, 1TSR with four of its mutated proteins. The energy for the wild-type and mutated proteins is calculated by using molecular dynamics simulations along with simulated annealing. Our results show significant differences in energy between hotspot mutations and the wild type. Based on the findings, we investigate the correlation between molar masses of the target residue and the relative energy with respect to the wild type. Our results indicate that the relative energy changes play a pivotal role in bioactivity, in conformity with observations in the rate of mutation in biology.
GEAMS: A Geographic Energy-Aware Multipath Stream-based routing protocol for WMSNs

Because sensor nodes operate on power limited batteries, sensor functionalities have to be designed carefully. In particular, designing energy-efficient packet forwarding is important to maximize the lifetime of the network and to minimize the power usage at each node. This paper presents a Geographic Energy-Aware Multipath Stream-based (GEAMS) routing protocol for WMSNs. GEAMS routing decisions are made online, at each forwarding node in such a way that there is no need to global topology knowledge and maintenance. GEAMS routing protocol performs load-balancing to minimize energy consumption among nodes using twofold policy: (1) smart greedy forwarding and (2) walking back forwarding. Performances evaluations of GEAMS show that it can maximize the network lifetime and guarantee quality of service for video stream transmission in WMSNs.
China-Zimbabwe Trade Relations in the 21st Century: An Analysis of the Trends, Patterns and Prospects

This study analyses the trends, patterns and prospects of Zimbabwe-China trade relations for the 16 years between years 2000 and 2016. The essence is to establish the direction of trade, trade intensity and trade composition of Zimbabwe-China trade as well as present a comparative analysis and assessment of the share of Zimbabwe-China trade vis-à-vis other trade partners. The study uses both primary and secondary data sources for analysis. The findings point to the fact that although Zimbabwe enjoyed a positive balance for the years preceding 2005, the country has since been recording widening trade deficits in its trade with China. With regard to trade intensity, the study reveals that on average, Zimbabwe’s trade with China accounts for less than 5 per cent of Zimbabwe’s trade with other African countries and the Rest of the World (RoW). In respect of trade composition, the study further found out that whilst Zimbabwean exports to China are largely dominated by the exportation of low value semi-processed and/or non-processed mining and agricultural commodities, China mainly exports high-end manufactures and consumer goods to Zimbabwe. As part of its recommendations, the study proposes the adoption of import regulation measures, exportoriented industrialization, establishment of China-Africa industrial capacity cooperation, and investment in manufacturing and industrial processing plants.
Assessing protein function using a combination of supervised and unsupervised learning

The determination of protein function using experimental techniques is time-consuming and expensive; the use of machine learning techniques to rapidly assess protein function may be useful in streamlining this process. The problem of assigning functional classes to proteins is complicated by the fact that a single protein can participate in several different pathways and thus can have multiple functions. It follows that the instances in the resulting classification problem can carry multiple class labels. We have developed a tree-based classifier that capable of handling multiply-labeled data: we call the resulting tree a recursive maximum-contrast tree (RMCT). The name derives from the way in which nodes in the tree are split; this is done by selecting the two training instances with maximum contrast (that is, the two training instances with maximum separation according to some distance measure) and using them as seeds in a clustering algorithm to form a partition of the training instances and hence of the feature space. We test our algorithm on protein phylogenetic profiles generated from 60 completely sequenced genomes, and we compare our results to those achieved using existing algorithms such as support vector machines and decision trees
A Parallel Pipelined Renderer for the Time-Varying Volume Data

This paper presents a strategy for efficiently rendering time-varying volume data sets on a distributed-memory parallel computer. Time-varying volume data take large storage space and visualizing them requires reading large files continuously or periodically throughout the course of the visualization process. Instead of using all the processors to collectively render one volume at a time, a pipelined rendering process is formed by partitioning processors into groups to render multiple volumes concurrently. In this way, the overall rendering time may be greatly reduced because the pipelined rendering tasks are overlapped with the I/O required to load each volume into a group of processors; moreover, parallelization overhead may be reduced as a result of partitioning the processors. We modify an existing parallel volume renderer to exploit various levels of rendering parallelism and to study how the partitioning of processors may lead to optimal rendering performance. Two factors which are important to the overall execution time are resource utilization efficiency and pipeline startup latency. The optimal partitioning configuration is the one that balances these two factors. Tests on Intel Paragon computers show that in general optimal partitionings do exist for a given rendering task and result in 40-50% saving in overall rendering time.
User Intention Mining in Bussiness Reviews: A Review

In recent times, the rapid use of social media sites like Facebook and Twitter has produced oceans of textual data from different sources like discussion channels, review websites and blogs, containing user's emotions, opinions, sentiments and certainly the intentions. Intention mining is becoming an emerging area in social computing, playing a key role in understating the needs, desires and wants of users/customers from business reviews, posts, and comments. However, a brief work in the field of intention mining regarding business-related reviews is still needed, and there lack of systematic literature review. This work aims at presenting a brief review of the literature with respect to intention mining from business-related online reviews including various techniques and methods employed. The results presented, show that this review will provide a roadmap for future researchers working in the field of business-related intention mining.
Opioid-Induced Constipation: Pathophysiology, Clinical Consequences, and Management

Although opioids offer potent analgesia for severe acute and chronic noncancer pain, adverse gastrointestinal effects potentially undermine their clinical utility. In particular, between 40% and 95% of patients develop opioid-induced constipation (OIC). Therefore, there is a consensus that patients should commence laxatives at the start of opioid therapy and continue throughout treatment. Nevertheless, laxatives are not routinely coprescribed with opioids. Even when concurrent laxatives are prescribed, approximately half the patients treated for OIC do not achieve the desired improvement. Moreover, laxatives do not target the underlying cause of OIC (opioid binding to the μ -receptors in the enteric system) and as such are not very effective at managing OIC. The failure of lifestyle modification and laxatives to treat adequately many cases of OIC led to the concurrent use of peripherally acting opioid antagonists (such as methylnaltrexone bromide and naloxone) to reduce the incidence of gastrointestinal adverse events without compromising analgesia. Judicious use of the various options to manage OIC should allow more patients to benefit from opioid analgesia. Therefore, this paper reviews the causes, consequences, and management of OIC to help clinicians optimise opioid analgesia.
On Multicomponent System Reliability with Microshocks-Microdamages Type of Components’ Interaction

Consider a two component parallel system. The defined new stochastic dependences of the component’ life-times are understood as a stochastic reflection of rather complicated components’ physical interactions. The interactions are assumed to obey some “continuous” pattern, valid until one of the components fails. According to that pattern some infinitesimal micro-damages in each component’ physical structure (caused by the remaining component’s “harmful” activity) are related to corresponding infinitesimal increments in the component’ failure rate. Based on this association between the physical failure mechanism and its much simpler probabilistic equivalence, we describe the latter analytically in terms of the lifetimes’ joint probability distribution; actually we constructed a wide class of such stochastic models. As a special case of the bivariate distributions we obtain the first bivariate Gumbel distribution along with its, perhaps first known, reliability interpretation.
