Associating Nearby Robots to Their Voices

It can be useful for a robot in a team to recruit the help of others after considering their poses in space. When the initiating robot is aware of the network addresses (or IDs) of the robots it may ask for cooperation over the network. But if the initiating robot is ignorant of their IDs then it becomes rather more complex or time consuming. In this paper, robots use a simple visual (locally sensed) gesture (such as a light being turned on or off) in addition to wireless messages to quickly and effectively establish a one-to-one association between physical location IDs and wireless IDs. This paper identifies, describes, formalizes, and then generalizes the problem of establishing a local association between neighboring robots’ physical location IDs (in the reference frame of an observing robot) and their wireless IDs. We describe three algorithms that solve this problem: two are deterministic algorithms and one is a probabilistic algorithm. Using the algorithms and formalism, we examine the structure underlying this association problem.
Evaluating attack time expenses for network security alert causal correlation

Network security alert causal correlation aims at correlating causal related security alerts into comprehensible attack scenarios. In this paper, we propose a novel correlation criterion by evaluating the time expenses of the attacks that trigger security alerts. By taking the attack time expenses as random variables and studying their probabilistic distribution, we can calculate the temporal correlation belief metric of any two candidate alerts. To testify the feasibility, a prototype system is designed, implemented and tested with the DARPA 2000 IDS evaluation dataset. Result shows that our method is effective and efficient, providing a strong complementary support for attack scenario construction.
Optimal filtering and control for first degree polynomial systems: Risk-sensitive method

The algorithms for the optimal filter and control have been obtained for systems with polynomial first degree drift term in the state and observations equations. Two cases are presented: systems with disturbances in L2 and systems with Brownian motion and parameter epsiv multiplying both in the state and observation equations. The algorithms of the optimal risk-sensitive filter are obtained in each case and their performance is verified and compared with the algorithms of the optimal Kalman-Bucy filter through an example. The solution to the optimal control risk-sensitive problem for stochastic system, and log-exp-quadratic cost function to be minimized is obtained. This algorithms are obtained using value function as solution of PDE HJB. These algorithms are compared with the traditional control algorithms through numerical example. The optimal risk-sensitive filter and control show better performance for large values of the parameter epsiv.
Network computing performance evaluation in message passing environment

This paper is based on joint research between Queen Mary, University of London, and Wuhan University of Technology, People's Republic of China, on the use of network computing for solving non-linear heat flow problems. A general formulation for system performance evaluation has been derived from measured results, which covers the network computing as well as multiprocessor computing. The Amdahl's law and Gustafson's modification for speedup have been uniformly explained from this formula. Some criterions of speedup, efficiency and granularity for network computing also have been suggested.
Heading Estimation for Indoor Pedestrian Navigation Using a Smartphone in the Pocket

Heading estimation is a central problem for indoor pedestrian navigation using the pervasively available smartphone. For smartphones placed in a pocket, one of the most popular device positions, the essential challenges in heading estimation are the changing device coordinate system and the severe indoor magnetic perturbations. To address these challenges, we propose a novel heading estimation approach based on a rotation matrix and principal component analysis (PCA). Firstly, through a related rotation matrix, we project the acceleration signals into a reference coordinate system (RCS), where a more accurate estimation of the horizontal plane of the acceleration signal is obtained. Then, we utilize PCA over the horizontal plane of acceleration signals for local walking direction extraction. Finally, in order to translate the local walking direction into the global one, we develop a calibration process without requiring noisy compass readings. Besides, a turn detection algorithm is proposed to improve the heading estimation accuracy. Experimental results show that our approach outperforms the traditional uDirect and PCA-based approaches in terms of accuracy and feasibility.
Influence of resistance exercise volume on recovery energy expenditure in women

Abstract The acute effects of resistance exercise on energy expenditure in the post-exercise period have not been well studied in women, even though they are at high risk for weight gain and so would benefit greatly from exercise-related increases in energy expenditure. The purpose of this study was to identify factors that influence recovery energy expenditure in women after an acute bout of resistance exercise. Seventeen healthy women aged 40–55 years completed an acute bout of resistance exercise followed by measurement of energy expenditure for 120 min of recovery. Body composition was measured via air displacement plethysmography. The resistance exercise bout consisted of three sets of 8–12 repetitions of eight exercises at 50% of one-repetition maximum (1-RM) for the first set and 80% 1-RM for the second and third sets. Oxygen consumption (VO2) was measured before and for 120 min after resistance exercise. Post-exercise energy expenditure data were analysed as 4-min means at 0, 20, 40, 60, 90, and 120 min of recovery. Mean (± s x ) training volume was 7604.1±450.64 kg and overall mean recovery energy expenditure was 133±6 kcal. Pearson's correlation analysis found no significant relationship between post-exercise energy expenditure and age, body mass index, exercise time or delay between cessation of exercise and commencement of metabolic measurement. Absolute (kg) lean mass was also not significantly related to energy expenditure at any time post-exercise, although relative (%) lean mass was during the late recovery period only (40 min of recovery: r = 0.49, P = 0.05; 60 min: r = 0.51, P = 0.04; 90 min: r = 0.63, P < 0.01). The factor most consistently related to post-exercise energy expenditure was total exercise volume, which had a moderately strong relationship through 90 min of the recovery period (0 min of recovery: r=0.49. P = 0.05; 20 min: r = 0.52, P = 0.03; 40 min: r = 0.53, P = 0.03; 60 min: r = 0.50, P = 0.04; 90 min: r=0.48, P = 0.05). In the present sample of women, acute post-exercise energy expenditure was influenced primarily by total training volume, although lean mass had a limited effect. Based on these findings, it is recommended that women be encouraged to lift at higher intensities (70–80% 1-RM) to maximize post-exercise energy expenditure and potentially promote fat loss.
Evaluation of Promising Malting Barley Varieties Using Agronomic and Quality Traits in Kenya

A study to select promising malting barley varieties was conducted at the University of Eldoret and Mau Narok in Kenya from June 2011 to July 2012. Two varieties due for release were compared with one commercial variety. Data on yield and quality components was subjected to ANOVA using SAS. Means were separated by LSD at α = 0.05. HKBL 1385-13 had superior grain yield than the control variety at both the Mau Narok and University of Eldoret sites by 500 kg ha (25%) and 1400 kg ha (37.8%) respectively. HKBL 1512-5 had significantly higher grain yields than the control at the Mau Narok site by 400 kg ha, but at the University of Eldoret, it had inferior yields, shorter spike length and a lower number of grains spike. However, it had consistently heavier grains throughout the study. Both HKBL 1512-5 (2.33 %) and HKBL 1385-13 (2.21 %) accumulated grain N-content beyond the acceptable level of 2.2 % at the Mau Narok site compared to 1.97 % and 1.87 % respectively at the University of Eldoret. Site differences were observed for the proportion of maltable grains. HKBL 1512-5 has inferior agronomic traits at both sites, except for plant stand establishment, 1000 kernel weight and % nitrogen accumulation in the grain at the Mau Narok site. The superior grain size of test variety HKBL 1512-5 can be used to improve barley varieties with superior yields but with inferior kernel size. Choice of appropriate variety for Mau Narok could be determined by the 1000 grain weight and % nitrogen accumulation in the grain, whereas, at the University of Eldoret, variety choice can be based on grain yield, the number of productive tillers per plant and grains per spike.
The effect of ingestion of egg and low density lipoprotein (LDL) oxidation on serum lipid profiles in hypercholesterolemic women

Egg is a major source of dietary cholesterol. The serum lipid response to egg shows marked individual variation, being partly genetically determined, and influence by ethnic groups and the overall diet response. In the present investigation, we investigated the effect of ingestion of egg and low density lipoprotein (LDL) oxidation on serum lipid profile in hypercholesterolemic women. Forty hypercholesterolemic women volunteers on a cholesterol-lowering diet (CLD) divided into 2 groups in a randomized controlled cross-over study of one egg per day (CLD + 1 egg) for 4-week and three eggs per day (CLD + 3 eggs) for 4-week, separated by 4-week period egg-free. The body weight, blood pressure, serum lipid profiles and LDL oxidation were measured at 4-week intervals. Cholesterol-lowering diet was applied throughout the study by a dietitian using a food exchange program and 3-day dietary recall every 4 weeks. Compared to the values obtained at baseline, the mean serum total cholesterol and LDL cholesterol of CLD + 3 eggs was not significantly different from baseline whereas of those of 4-week of egg-free period and CLD + 1 egg were significantly decreased (238.3±2.9 mg/dL and 228.3±4.7 mg/dL) compared to the baseline (252.2±5.9 mg/dL) as was LDL cholesterol (161.2±3.0 mg/dL and 155.7±4.8 mg/dL) compared to the baseline (177.5± 6.0 mg/dL) (p<0.05). The study showed there were no significantly difference the body weight, blood pressure, HDL cholesterol, triglycerides or LDL oxidation during the study. However, serum total cholesterol and LDL cholesterol of 1 or 3 eggs per day after 4-week of egg consumption was not significantly higher than the egg-free period. The study suggests that in hypercholesterolemic women who are on cholesterol-lowering diet, consuming one or three eggs per day did not raise serum cholesterol or LDL cholesterol levels at 4 weeks or result in any change in LDL oxidation.
Evaluation by females and males of speeches worded in the masculine, feminine, or genderinclusive reference form

A random sample of female and male students (n= 408) representing three age groups (11, 14, and 17 years) evaluated speeches that were worded using either the masculine (boy, he, his), feminine (girl, she, her), or gender-inclusive (boy/girl, she/he, her/his) forms of person reference. Significant interaction effects were found between forms of reference on the one hand, and subjects’gender and age on the other hand. The main features of the results were that (1) at age 11, both females and males upgraded the masculine over the feminine reference form; (2) at age 14 and 17, female subjects upgraded, whereas male subjects continued to downgrade, the feminine relative to the masculine form; and (3) the gender-inclusive form was evaluated most positively, or at least as positively as the gender-specific forms. These features were interpreted as reflecting subjects’gender identification triggered by the particular reference form.
miR-21 expression and clinical outcome in locally advanced pancreatic cancer: exploratory analysis of the pancreatic cancer Erbitux, radiotherapy and UFT (PERU) trial

Background Locally advanced pancreatic cancer (LAPC) is associated with high mortality, and biomarker-driven treatment approach is currently lacking. This study evaluated safety and efficacy of a combination approach of chemotherapy followed by chemo-radiotherapy (CRT) +/− cetuximab, and the prognostic role of miR-21 in patients with LAPC treated with a multimodality approach. Patients and Methods This was a randomised phase II trial in which patients with inoperable LAPC were offered gemcitabine and capecitabine (GEM-CAP) for 16 weeks. Patients with stable disease or response after GEM-CAP were randomised to capecitabine or UFT plus radiotherapy (RT) (A), or capecitabine or UFT plus cetuximab plus RT (B). The primary outcome of the study was overall survival (OS). Clinical outcome was compared according to baseline circulating miR-21 levels. Results 17 patients were enrolled and treated with GEM-CAP, with 13 patients achieving disease control and being randomised to arms A (n:7) and B (n:6). After a median follow-up of 61.2 months, median progression free survival (PFS) was 10.4 months and 12.7 months, median OS was 15.8 months and 22.0 months in arms A and B respectively (p > 0.05). Patients with high baseline plasma miR-21 had worse PFS (3.5 vs. 12.7 months; p:0.032) and OS (5.1 vs 15.3 months; p:0.5) compared to patients with low miR-21. Circulating miR-21 levels reflected miR-21 expression within the tissues. Conclusions Addition of Cetuximab to CRT following induction chemotherapy did not improve survival. High miR-21 baseline plasma expression was associated with poor clinical outcome in LAPC patients treated with induction chemotherapy followed by chemo-radiotherapy.
Recruiting and Retaining Teachers in the UK: An Analysis of Graduate Occupation Choice from the 1960s to the 1990s

This paper examines the market for teachers in the UK from 1960 to 1996 using graduate cohort data from 5 separate cohorts. We find that relative wages in teaching compared to alternative professions have a significant impact on the likelihood of graduates choosing to teach, although the impact depends upon the market situation at the time. The wage effect on the supply of teachers is strongest at times of low relative teachers' wages, or following a period of decline in those wages. It is also strongest for those individuals who have more recently graduated. (This abstract was borrowed from another version of this item.)

AUTOMATIC MAPPING FROM ULTRA-LIGHT UAV IMAGERY

This paper presents an affordable, fully automated and accurate mapping solutions based on ultra-light UAV imagery, which is commercialized by Pix4D. We show interesting application in the field of UAV mapping, analyse the accuracy of the automated processing on several datasets. The accuracy highly depends on the ground resolution (flying height) of the input imagery. When chosen appropriately this mapping solution can compete with traditional mapping solutions that capture fewer high-resolution images from airplanes and that rely on highly accurate orientation and positioning sensors on board. Due to the careful integration with recent computer vision techniques, the result is robust and fully automatic and can deal with inaccurate position and orientation information which are typically problematic with traditional techniques.
EASE: EPC as a service to ease mobile core network deployment over cloud

The objective of this article is to demonstrate the feasibility of on-demand creation of cloud-based elastic mobile core networks, along with their lifecycle management. For this purpose the article describes the key elements to realize the architectural vision of EPC as a Service, an implementation option of the Evolved Packet Core, as specified by 3GPP, which can be deployed in cloud environments. To meet several challenging requirements associated with the implementation of EPC over a cloud infrastructure and providing it "as a Service," this article presents a number of different options, each with different characteristics, advantages, and disadvantages. A thorough analysis comparing the different implementation options is also presented.
Black-Box Performance Control for High-Volume Non-Interactive Systems

This paper studies performance control for high-volume non-interactive systems, and uses IBM Tivoli Netcool/Impact--a software product in the IT monitoring and management domain--as a concrete example. High-volume non-interactive systems include a large class of applications where requests or processing tasks are generated automatically in high volume by software tools rather than by interactive users, e.g., data stream processing and search engine index update. These systems are becoming increasingly popular and their performance characteristics are radically different from those of typical online Web applications. Most notably, Web applications are response time sensitive, whereas these systems are throughput centric. This paper presents a performance controller, TCC, for throughput-centric systems. It takes a black-box approach to probe the achievable maximum throughput that does not saturate any bottleneck resource in a distributed system. Experiments show that TCC performs robustly under different system topologies, handles different types of bottleneck resources (e.g., CPU, memory, disk, and network), and is reactive to resource contentions caused by an uncontrolled external program.
Cultural Differences in Child Rearing

To study cultural differences in child-rearing practices, 38 middle-class immigrant Chinese mothers and 38 middle-class Caucasian American mothers of 3- to 8-year-old children completed the Parenting Dimensions Inventory (PDI) and the Parenting Goals Questionnaire (PGQ). Comparison of the PDI scale scores revealed differences on all but the reasoning dimension. Caucasian American mothers scored higher on sensitivity, consistency, nonrestrictiveness, nurturance, and rule setting, whereas immigrant Chinese mothers scored higher on physical punishment and yelling at the child. Examination of the parenting goals revealed no cultural main effect, however, a main effect was found for child's age. Both immigrant Chinese and Caucasian American mothers place more emphasis on manners, school-related skills, and emotional adjustment during the early elementary school years (6 to 8 years of age) than during the preschool years (3 to 5 years of age). Results related to terns of the need for immigrant Chinese to maintain ties to their culture of origin and to accommodate to the socialization practices of the host culture.
Rethinking Risk Assessment. The MacArthur study of Mental Disorder and Violence

[][1] Over-funded, over-hyped, and over there. It is impossible for a British psychiatrist to look at the MacArthur study without a twinge, if not a spasm, of envy. There are many reasons - 8 million to be specific, that being the dollar cost of this epic. I mean to say, in England,
Human T cell hybridomas producing cytotoxic lymphokines: induction of lymphotoxin release and killer cell activity by anti-CD3 monoclonal antibody or lectins and phorbol ester.

Human T cell hybrids were constructed between lectin-activated peripheral blood lymphocytes and CEM.TET1, a variant of the CEM T lymphoblastoid cell line. Hybrids were screened for their ability to produce cytotoxic lymphokines and interleukin-2 (IL-2) following lectin activation. Five hybrids were identified that released significant levels (greater than 75 units/ml) of cytotoxic activity that was detected on the murine L929 target cells; three hybrids were identified that produced IL-2. Cell surface phenotype of the T cell hybrids did not correlate with their ability to produce these lymphokines. The II-23 hybrid (CD3+;4+) produced an inducible cytotoxic activity that was fully neutralized by anti-lymphotoxin antibodies. The release of lymphotoxin (LT) rapidly attained maximum levels 12 hrs to 24 hrs after lectin activation; IL-2 production was maximum at 48 hrs. The induction of LT and IL-2 release required similar membrane stimulating agents. The phorbol ester, phorbol 12-myristate 13-acetate (PMA) in combination with phytohemagglutinin or concanavalin A, were required for maximal release of LT and IL-2. Anti-CD3 monoclonal antibodies coupled to agarose, but not anti-T200-agarose, induced the release of high levels of LT and IL-2. Soluble anti-CD3 was not sufficient to induce IL-2 or LT release from the II-23 hybrid; however, soluble anti-CD3 combined with PMA was a strong stimulus for lymphotoxin and IL-2 release. The II-23 hybrid also functioned as a cytotoxic T cell line in a 51Chromium release assay. Induction of killer cell function required similar perturbation of Ti/CD3 complex. This human T cell hybrid line offers an inducible model system for the simultaneous study of the molecular events regulating the production of growth inhibitory/cytotoxic (LT) and growth promoting (IL-2) lymphokines and cytotoxic T cell function.
The motivation behind unsanctioned violence in international rugby: A case study of a former elite player

At focus in this case study was the participant's perception of, and personal involvement in, rugby violence. The participant was a 50-year-old ex-international and former British and Irish Lions rugby union player. A qualitative approach informed by reversal theory and incorporating retrospective semi-structured interview procedures with inductive and deductive elements was used to explore a number of topics related to his rugby playing career, including rugby violence. Among other statements related to play and power violence, the participant described his experience of three major incidents involving personal rugby violence. Each incident resulted in injury to the opposing player which required extensive medical attention. Two of the reported incidents supported previous reversal theory-based research findings related to the motivation behind anger violence in sport. The third incident illustrated a type of sport violence not previously identified in reversal theory-based sport research. It was termed “protective” or “supportive” violence, where an athlete comes to the aid, rescue or defence of a teammate. The findings provide valuable new insights on rugby violence, adding to sport psychology's understanding of the motivational processes involved.
SELF-EFFICACY, SPECIAL EDUCATION STUDENTS, AND ACHIEVEMENT: SHIFTING THE LENS

Self-efficacy is a cognitive theory that surfaced in the 1970’s. In the past 15 years, it has gained more attention as an important component to understand in furthering the academic achievement of special education students. Varying levels of self-efficacy can affect how a student perseveres when a task is difficult, and can be a predictor of academic achievement. In this literature review, 60 articles were retrieved through the initial Boolean phrase search. After inclusion and exclusion criteria were applied, 18 articles remained. Careful review of these articles revealed three major themes regarding selfefficacy in students receiving special education services. The following articles provide insight on how self-efficacy impacts academic success, motivation, and effort in the special education population, along with how teachers and specialists can enhance and foster self-efficacy through instructional practices. Implications are then discussed on how shifting instructional interventions and teacher interactions with students in the classroom could improve student self-efficacy and consequently improve their academic achievement.
