Paced and Self-Pacing Performance on a Simple Motor Task

T h e question of whether perceptual-motor tasks are performed better when people work at their own speed, or when they work at a set pace is still an open one. The majoriry of the evidence seems to be in favor of self-pacing in tasks where the criterion of performance is concerned with accuracy (Conrad, 1953, 1955, 1960; Vince, 1949; Leonard, 1958) . Most studies, however, have used well-practised tasks, or concerned themselves with performance during training. W e propose to examine the performance after knowledge of results is removed for Ss trained with paced rates and self-pacing under a knowledge of results technique. What pacing rates should we adopt? In studies of the effect of pacing rate, some Es have demonstrated the advantage of a "short" interval (rate faster than the average self-pacing rate) (Bills & Shapin, 1936) and some of a "long" one ( the slowest rate in the range studied) (Sampson, 1956, 195Sa, 1958b, 1961; Bilodeau & Bilodeau, 1958b). Bilodeau and Bilodeau (1958b) and McGuigan (1959) , however, point out that in tasks where knowledge of results is given, the effect of interval length is confounded with that of the point in the interval a t which knowledge is given. A method of supplying knowledge of results has recently been described which permits the comparison of the unconfounded effects of intervals of different length. Lavery (1962) has shown that delaying information to the end of a 20-trial block of trials, while producing slower rise in performance under training than does knowledge after every trial, leads to greater retention. Other techniques of information delay (Bilodeau, 1956; Brackbill & Kappy, 1962; Lavery & Suddon, 1962; Suddon & Lavery, 1962 ) produced the same effect and also demonstrated a dependence of level of retention performance on that reached in training. The present study was concerned with performance during training and after knowledge had been denied (retention) of three differently paced groups trained by a technique of information delay ( a graph of performance at the end of every 1 0 trials). One group was trained with a short interval, another with a long one and members of the third group set their own interval length.
Amyloid-beta binds catalase with high affinity and inhibits hydrogen peroxide breakdown.

Amyloid-beta (Abeta) specifically bound purified catalase with high affinity and inhibited catalase breakdown of H(2)O(2). The Abeta-induced catalase inhibition involved formation of the inactive catalase Compound II and was reversible. Catalase<-->Abeta interactions provide rapid functional assays for the cytotoxic domain of Abeta and suggest a mechanism for some of the observed actions of Abeta plus catalase in vitro.
Lending Fraud Detection : A Big Data Approach

P2P lending directly connects borrowers and lenders without a financial institution as the intermediary. This new form of crowdfunding brings lenders more investment opportunities, but also poses unprecedented risks of default and fraud. This research-in-progress paper focuses on a specific type of fraud, loan request fraud, which may be unique to lenders on Chinese P2P lending sites due to the lack of nationwide credit rating systems in China. We propose research questions surrounding the problem of loan request fraud (its types, features, and detection methods) and present our research methodology and project plans. Specifically, we plan to develop data mining based methods and employ a big data approach to address our research questions. With the help of large volumes of data from a variety of sources, we will be able to find ways to leverage rich datasets about user behaviors and transaction histories to detect loan request fraud more effectively and efficiently.
A boosting algorithm with subset selection of training patterns

This paper proposes a boosting algorithm of fuzzy rule-based systems for pattern classification problems. In the proposed algorithm, several fuzzy rule-based classification systems are incrementally constructed from a small number of training patterns. A subset of training patterns for constructing a fuzzy rule-based classification system is chosen according to weights associated to them. The weight for a training pattern is high when it is correctly classified many times. On the other hand, a low weight is assigned to those training patterns that are misclassified many times. Training patterns with a low weight are included in a subset of training patterns for constructing a single fuzzy rule-based classification system. We select the same number of training patterns from each class so that the bias in the number of training patterns among different classes is minimized. In computer simulations, we examine the performance of the boosting algorithm for the fuzzy rule-based classification systems on several real-world pattern classification problems.
A fixed-parameter algorithm for a routing open shop problem: unit processing times, few machines and locations

The open shop problem is to find a minimum makespan schedule to process each job $J_i$ on each machine $M_q$ for $p_{iq}$ time such that, at any time, each machine processes at most one job and each job is processed by at most one machine. We study a problem variant in which the jobs are located in the vertices of an edge-weighted graph. The weights determine the time needed for the machines to travel between jobs in different vertices. We show that the problem with $m$ machines and $n$ unit-time jobs in $g$ vertices is solvable in $2^{O(gm^2\log gm)}+O(mn\log n)$ time.
Propagation of blood clotting in the complex biochemical network of hemostasis is described by a simple mechanism.

Hemostasis is the complex biochemical network that controls blood clotting. We previously described a chemical model that mimicked the dynamics of hemostasis based on a simple regulatory mechanisma threshold response due to the competition between production and removal of activators. Here, we used human blood plasma in phospholipid-coated microfluidic channels to test predictions based on this mechanism. We demonstrated that, for a given geometry of channels, clot propagation from an obstructed channel into a channel with flowing blood plasma is dependent on the shear rate in the channel with flowing blood plasma. If confirmed in vivo, these results may explain clot propagation from a small vessel to a larger, clinically relevant vessel. In addition, these results would further validate the use of modular mechanisms, simplified chemical models, and microfluidics to study complex biochemical networks.
A Study on RC Columns and Slabs and Restoration of RC Columns of an Existing Multistoried Building

The paper analyses the deficiencies in the construction of a multistoried RC framed building and assessed the real strength gained by the RC elements like columns, beams and slabs. Nondestructive tests were conducted and representative cylindrical core samples were taken out from the RC elements and analyzed in the standard laboratory. The results compared with IS 456:2000 reveals that the major parts of slabs in ground, first and second floor from the RC elements in the structure are satisfying the minimum concrete grade M20. However, some of the columns in ground, first and second floor are not satisfying the minimum concrete grade M20 that required as per IS 456:2000. This structure requires immediate attention of strengthening the existing RC columns by adopting suitable rehabilitation techniques.
The role of sibutramine in weight reduction.

BACKGROUND The effectiveness of pharmacologic support with sibutramine along with the preservation of dietary and regimen measures is shown in a group of long-term treated patients at the Metabolic Clinic of the University Hospital in Hradec Králové. METHODS In ambulatory patients, basic anthropometric parameters as body weight, BMI, waist circumference and the total amount of adipose tissue were compared before substitution with 10 mg sibutramine and after a four-month therapy. This group included 94 patients who were administered the same dose of sibutramine for the whole period of time. This group consisted of 37 men and 57 women. RESULTS After a four-month therapy with sibutramine there was a mean reduction in weight by 7.9 ± 3.8 kg in the monitored group of patients. Their BMI was reduced by 2.3 ± 1.5 kg/height2 and the waist circumference by 4.4 ± 3.8 cm. The decrease in the percentage of the total body lipid was 2.9 %. CONCLUSION Despite a surprising decision of the European Drug Agency to suspend the registration of sibutramine in the whole of Europe since January 2010 we can state that in our patients we have proven a positive effect of sibutramine substitution on their weight reduction (Tab. 1, Ref. 19).
Reliability of the psychosocial schedule for school age children.

The Psychosocial Schedule (PSS) is an instrument derived from several pre-existing rating scales, which was designed to measure and record clinical data (other than the symptoms of the present episode of disorder) which are likely to be relevant to child psychiatric disorder. These data include: developmental and past symptomatic history, demographics, family functioning, and relationships. Reliability was tested by interrater and test-retest designs with mothers of prepubertal children. Overall, the instrument appeared to be quite reliable. Although it is subject to minor modifications, especially for use with adolescents, it is concluded that the PSS is a practical instrument which should be tested now in adolescents, and can be utilized in future studies with prepubertal subjects.
Effect of Feed Rate and Solid Retention Time (SRT) on Effluent Quality and Sludge Characteristics in Activated Sludge Systems Using Sequencing Batch Reactors

A critical element to the successful operation of activated sludge systems is efficient solid liquid separation achieved by bioflocculation. Bioflocculation refers to the process of microbial aggregation to form activated sludge flocs, dependent on the interaction of exocellular polymeric substances (EPS) to form the matrix that holds microbes, other organics and inorganic particles in a flocculent mass. Numerous factors affect bioflocculation; two key parameters are the Solid Retention Time (SRT) and the substrate loading rate. The latter is related to the two basic designs in activated sludge bioreactor configurations: the Plug Flow Reactor (PFR) and the Completely Stirred Tank Reactor (CSTR). PFR systems have a high substrate loading rate, whereas CSTRs have a low substrate loading rate. Research has shown that the PFR configurations produce better sludge quality, in terms of settleability and dewaterability, and subsequently better effluent quality than CSTR systems. In this experiment, the effect of SRT and substrate loading rate on activated sludge was investigated using bench scale SBRs. PFR and CSTR configurations were simulated by adjusting the fill period to be shorter or longer respectively. A series of SBRs were operated, each with an operating volume of 6L, to obtain data for PFR (fast feed) versus CSTR (slow feed) configurations at 10 Day, 5 Day and 2 Day SRTs. Effluent quality was monitored by measuring effluent TSS, VSS, total and soluble COD and soluble biopolymers. Sludge quality was monitored for the aerobic phase by measuring total and suspended solids, total and suspended volatile solids, Sludge Volume Index (SVI), Capillary Suction Time (CST) and Zeta Potential. Anaerobic digestibility was measured for the sludge produced in these systems by measuring gas production, similar to estimating biogenic methane potential (BMP) and determining short term odor productions, specifically Total Volatile Organic Sulfur Compounds (TVOSCs). As expected the change in feeding pattern and SRTs affected the effluent and sludge quality during the aerobic operation phase. Effluent quality was found to be better for the fast feed system at all SRTs, with all monitored parameters being of similar or significantly lower concentration than for the slow feed system. In terms of sludge quality, the fast feed system was found to retain more of its biomass in solution, indicating better flocculation and settleability in this system. COD was given a lower rank as an effluent quality indicator, since the 5 Day and 2 Day SRT datasets did not correlate well with other datasets, specifically effluent TSS and biopolymers. The data was included because it is believed that the trends were accurate
A low complexity physical-layer identity detection for 3GPP Long Term Evolution

Long Term Evolution (LTE) is one of radio access technology that has been intensively studied in 3GPP standard group to support instantaneous downlink and uplink peak data rates of 100Mb/s and 50Mb/s within 20 MHz downlink and uplink spectrum allocations, respectively. Employing OFDMA and scalable bandwidth scheme in downlink access impact on increasing cell search complexity. In this paper we propose low complexity physical layer identity detection as one of cell search step using finite impulse response (FIR) and partial cross-correlation. Our propose scheme is done in time domain instead of frequency to avoid FFT involvement and decrease processing latency. As a result, the proposed scheme just needs 20169 LUTs when implemented in FPGA Virtex-4 XC4VLX200 and can perform physical layer identity detection for SNR 0dB or higher in AWGN channel by probability more than 95%.
Lymphatic mapping with isosulfan blue dye in squamous cell carcinoma of the head and neck.

OBJECTIVE To determine whether intraoperative lymphatic mapping with isosulfan blue dye and sentinel lymph node biopsy accurately demonstrates the pathway of regional metastases from mucosal sites in squamous cell carcinoma of the head and neck. DESIGN A prospective clinical study of intraoperative lymphatic mapping. SETTING An academic tertiary referral center. PATIENTS Patients with previously untreated squamous cell carcinoma of the head and neck whose surgical treatment included neck dissection. INTERVENTION Injection of isosulfan blue dye into the mucosa surrounding squamous cell carcinomas of the upper aerodigestive tract during cervical lymphadenectomy. OUTCOME MEASURES Correlation of the pathologic findings in the blue sentinel lymph node with those in the remaining cervical lymphatics. RESULTS No blue-stained cervical lymphatics were identified after injection of the mucosa surrounding the primary squamous cell carcinoma with isosulfan dye. CONCLUSION The technique of intraoperative lymphatic mapping with isosulfan blue dye requires further study before it can be used for the detection of occult cervical metastases in squamous cell carcinoma of the head and neck.
Analysis of Mouse Growth Plate Development

To investigate skeletal development, pathophysiological mechanisms of cartilage and bone disease, and eventually assess innovative treatments, the mouse is a very important resource. During embryonic development, mesenchymal condensations are formed, and cells within these mesenchymal condensations either directly differentiate into osteoblasts and give origin to intramembranous bone, or differentiate into chondrocytes and form a cartilaginous anlage. The cartilaginous anlage or fetal growth plate is then replaced with bone. This process is also called endochondral bone development, and it is responsible for the generation of most of our skeleton. Here we discuss in detail the most common in vivo and in vitro techniques our laboratory is currently using for the analysis of the mouse fetal growth plate during development. © 2016 by John Wiley & Sons, Inc.
Effects of a home-based family intervention on adolescent alcohol use and misuse.

OBJECTIVE Systematic evaluation of theoretically and empirically based family programs to prevent adolescent alcohol use/misuse is limited. Data presented here are from a longitudinal study evaluating a home-based universal adolescent alcohol use prevention program. The intervention was designed to enhance protective factors and minimize risk factors identified as influencing adolescent alcohol use. METHOD A randomized pretest/posttest repeated measures design was used. Adolescents (N = 428; 54% females, 86% European American) and their parents were recruited from three Midwestern school districts. Families were randomly assigned to either a three-session family intervention or a no-intervention control condition. Pretest data collection and the intervention occurred when the adolescents were in fourth grade, and a booster intervention was given in seventh grade. Posttest data collection was completed each year for 4 years in the classroom for adolescents. RESULTS The intervention was associated with a reduction in alcohol use (F = 5.16, 4/421 df, p < .001) and misuse (F = 3.08, 4/421 df, p < .05) for those adolescents in the intervention condition who were not using alcohol prior to the initiation of the program, but not for those who were using alcohol before initiation of the program. CONCLUSIONS The results support the possible effectiveness of the family intervention as a universal prevention program for decreasing initiation of alcohol use and subsequent misuse for the majority of adolescents who do not report prior drinking. However, additional intervention approaches appear necessary for adolescents who have already used alcohol.
Atmospheric processes governing the Northern Hemisphere annular mode/north Atlantic Oscillation

The North Atlantic Oscillation, referred to herein as the Northern Hemisphere annular mode (NAM), owes its existence entirely to atmospheric processes. In this chapter, we review the structure of the NAM in the atmospheric general circulation, discuss opposing perspectives regarding its physical identity, examine tropospheric processes thought to give-rise to NAM-like variability, and review the role of the stratosphere in driving variability in the NAM. The NAM is characterized by a deep, nearly barotropic structure, with zonal wind perturbations of opposing sign along ∼55° and ∼35° latitude. It has a pronounced zonally symmetric component, but exhibits largest variance in the North Atlantic sector. During the Northern Hemisphere (NH) winter, the NAM is strongly coupled to the circulation of the NH stratosphere. The NAM also affects tropical regions, where it perturbs the temperature and wind fields of both the tropical troposphere and stratosphere. The structure of the NAM is remarkably similar to the structure of the leading mode of variability in the Southern Hemisphere circulation. The processes that give rise to annular variability are discussed. In the troposphere, the NAM fluctuates on timescales of ∼10 days and is associated with anomalous fluxes of zonal momentum of baroclinic waves across ∼45°N. It is argued that the tropospheric component of the NAM exhibits largest variance in the Atlantic sector where the relatively weak thermally driven subtropical flow and the relatively warm lower boundary conditions at subpolar latitudes permit marked meridional excursions by baroclinic waves. In the stratosphere, fluctuations in the NAM evolve on timescales of several weeks. Evidence is presented that long-lived anomalies in the stratospheric NAM frequently precede similarly persistent anomalies in the tropospheric NAM. It is argued that variability in the lower stratospheric polar vortex yields a useful level of predictive skill for NH wintertime weather on both intraseasonal and seasonal timescales. The possible dynamics of these linkages are outlined. The recasting of the North Atlantic Oscillation as an expression of an annular mode has generated a debate over the physical identity of the mode in question. This debate attests to the absence of a unique theory for the existence of annular modes in the first place. Our current understanding of the fundamental processes to which the NAM owes its existence is discussed.
Effect of Various Pollen Sources to Ability Fruit Set and Quality in ‘Long Red B’ Wax Apple

By hand pollination was conducted to evaluated different pollen sources and their affects on fruit set and quality of wax apple. The following parameters were recorded: fruit set, seed set, fruit characteristics. Results showed that fruit set percentage with seed were significantly high in ‘Long Red B’ when ‘Black’, ‘Thyto’ were used as pollen parents. Pollen of ‘Black’, ‘Thyto’ resulted in high fruit weight, fruit diameter, fruit length, bigger flesh thickness, better total soluble solids as compared with other pollens. The observation of pollen-growth in vitro revealed that pollen germination at 15% sucrose concentration are required for optimum pollen germination with the high pollen germination were found in ‘Black’, ‘Thyto’. From the result, we concluded that ‘Black’, ‘Thyto’ were proved to be good pollinizers in ‘Long Red B’. Therefore, artificial cross-pollination using ‘Black’, ‘Thyto’ as pollinizers were strongly recommended for ‘Long Red B’ cultivar in wax apple orchard. Keywords—Wax apple, pollination, pollen source, in vitro, fruit quality.
Evaluation of Java PathFinder Symbolic Execution Extension

Executions of a system can follow di erent execution paths depending on the inputs to the system. In symbolic execution constraints over input values are generated during execution and these constraints are used to guide the execution so that every distinct execution path will be covered. Symbolic execution has gained a renewed interest among researchers since the recent advancements in decision procedures that now allow many path constraints to be solved e ciently. In this paper we give an overview of the techniques used in symbolic execution extension of a model checking tool called Java PathFinder and show how it can be used to symbolically execute sequential and concurrent Java programs. We will describe what parts of the tool are currently functional and what parts are planned or under development. To give the reader a better understanding of the advantages and disadvantages of the tool, we also describe shortly two other tools using symbolic execution.
Detection and Visualization of Arabic Emotions on Social Emotion Map

Abstract. In the context of smart cities and Internet of Things (IoT), there are many trending contents on the social networks that reflect the picture of the community or their interest. In this paper, we propose a model that automatically collect trending social data and analyze them automatically. The model explores trending contents, overall attitude of textual contents and the relationships among the participated users. The analysis of the data collected involves the analysis of the user as well as the community in terms of interest, embedded tags, and the corresponding contents. The model is trained using data collected from Twitter, the famous growing social network, using hashtags, emoticons, geo-tags, and user profiles. We focus in this work on the Arabic contents to visualize the resulted emotions on a real world map.
An Intrusion Detection System for IEC61850 Automated Substations

This paper proposes the use of an intrusion detection system (IDS) tailored to counter the threats to an IEC61850-automated substation based upon simulated attacks on intelligent electronic devices (IEDs). Intrusion detection (ID) is the process of detecting a malicious attacker. It is an effective and mature security mechanism. However, it is not harnessed when securing IEC61850-automated substations. The IDS of this paper is developed by using data collected by launching simulated attacks on IEDs and launching packet sniffing attacks using forged address resolution protocol (ARP) packets. The detection capability of the system is then tested by simulating attacks and through genuine user activity. A new method for evaluating the temporal risk of an intrusion for an electric substation based upon the statistical analysis of known attacks is also proposed.
