Reversed clock phenomenon: A right-hemisphere syndrome

Sensory stimuli are commonly mislocalized to the corresponding site on the opposite side of the body or space.1-3 Patients with visual neglect often transpose the locations of objects in scenes that they describe from memory.4 The clock-drawing task is useful in assessing impairments of spatial executive function and in discriminating them from nonexecutive constructional failure.5,6 We identified 6 of 380 consecutive patients (1.6%) with stroke in the right hemisphere who showed spontaneously reversed placement of the numbers of a clock without number omissions. Three of these six patients also showed mental imagery reversal in their descriptions of remembered scenes of their environment. The clock-drawing task was performed by giving instructions to the patients to place the numbers of a clock on a previously drawn circle. Reversed number sequencing on clock drawing was resolved in 2 weeks in all patients. None of the patients with left-hemisphere stroke (n = 320) showed reversed clock drawing. Radiologic examinations revealed infarcts in three patients and hemorrhage in the other three patients in either the cortical or subcortical areas (figure). Figure. Redrawn templates show clock drawings and the site of …
Childhood Socioeconomic Status Amplifies Genetic Effects on Adult Intelligence

Studies of intelligence in children reveal significantly higher heritability among groups with high socioeconomic status (SES) than among groups with low SES. These interaction effects, however, have not been examined in adults, when between-families environmental effects are reduced. Using 1,702 adult twins (aged 24–84) for whom intelligence assessment data were available, we tested for interactions between childhood SES and genetic effects, between-families environmental effects, and unique environmental effects. Higher SES was associated with higher mean intelligence scores. Moreover, the magnitude of genetic influences on intelligence was proportional to SES. By contrast, environmental influences were constant. These results suggest that rather than setting lower and upper bounds on intelligence, genes multiply environmental inputs that support intellectual growth. This mechanism implies that increasing SES may raise average intelligence but also magnifies individual differences in intelligence.
Acute effect of a complex training protocol of back squats on 30-m sprint times of elite male military athletes

[Purpose] The aim of this study was to determine the acute effect temporal of a complex training protocol on 30 meter sprint times. A secondary objective was to evaluate the fatigue indexes of military athletes. [Subjects and Methods] Seven military athletes were the subjects of this study. The variables measured were times in 30-meter sprint, and average power and peak power of squats. The intervention session with complex training consisted of 4 sets of 5 repetitions at 30% 1RM + 4 repetitions at 60% 1RM + 3 repetitions of 30 meters with 120-second rests. For the statistical analysis repeated measures of ANOVA was used, and for the post hoc analysis, student’s t-test was used. [Results] Times in 30 meter sprints showed a significant reduction between the control set and the four experimental sets, but the average power and peak power of squats did not show significant changes. [Conclusion] The results of the study show the acute positive effect of complex training, over time, in 30-meter sprint by military athletes. This effect is due to the post activation potentiation of the lower limbs’ muscles in the 30 meters sprint.
A Conference Key Distribution Scheme in Tree Hierarchies

A new conference key distribution scheme is proposed in this study for access control in a hierarchy. A group of users with a different security class can generate a common secret key over a public channel so that a secure electronic conference can be held. The security classes form a hierarchy such that users in a higher security class can obtain a secret session key with users in the same or lower security classes. However, the opposite situation is not permitted.
Understanding the Roles of the Manager in Agile Project Management

Agile project management (APM) does away with the role and the job title of the manager and instead places emphasis on self-organizing teams. However, recent surveys show that the job title of managers, particularly the project manager, is in existence on a significant number of agile projects. At the same time there is very little empirical evidence on the manager's role in an APM framework. To address this issue, a Grounded Theory study involving 20 software professionals from 18 different organizations which employed Agile Software Development (ASD) was carried out. The key finding of this preliminary study is the identification of the four roles played by managers on agile teams: mentor, coordinator, negotiator, and process adapter. As a mentor, the manager guides and supports the team in agile practice; the coordinator facilitates and coordinates the teams functioning; the negotiator takes care of the budget and customer requirements; and as a process adapter, the manager customizes agile and also implements agile-waterfall hybrids. The results of this study highlight the need for in-depth research into the different management roles and functioning of the agile team and manager. Additionally, this study will help guide new and existing managers to better understand the various aspects and boundaries of their new roles on agile projects and enable them to better facilitate self-organizing teams.
Post-Placement Voltage Island Generation

High power consumption will shorten battery life for handheld devices and cause thermal and reliability problems. One way to lower the dynamic power consumption is to reduce the supply voltage. Multi-supply voltage (MSV) is introduced to provide higher flexibility in controlling the power and performance trade-off. In region-based MSV, circuits are partitioned into "voltage islands" where each island occupies a contiguous physical space and operates at one supply voltage. In a work by Wu et al. (2005), this supply voltage partitioning problem is addressed, and the input circuit is partitioned into a slicing structure with every voltage island rectangular in shape. This unnecessary restriction on the structure and island shapes has caused a significant degradation in the solution quality. In this paper, we propose a method to solve this voltage island generation problem without these restrictions. Experimental results have shown that our approach is fast and can improve the solution quality significantly. In some data sets, only two voltage islands are needed to satisfy the same power consumption bound while the approach by Wu et al. (2005) will generate nineteen
A Comparison of Path Planning Algorithms for Omni-Directional Robots in Dynamic Environments

The scope of this paper is to analyze and compare three path planning methods for omni-directional robots, which are based on a) the bug algorithm, b) the potential fields algorithm, and c) the A* algorithm for minimum cost path with multiresolution grids. The approaches are compared in terms of computational costs and the resulting path lengths. Results obtained indicate that the bug algorithm is a suitable choice for this type of application as its computational cost is lower than that of the other methods. Furthermore, minor modifications of the standard bug algorithm, such as the tangent following modification, allow the path planner to handle well the situations encountered in typical multi-robot environments
Using problem based learning to support transdisciplinarity in an HCI education

In this paper we advocate the development of transdisciplinary educational programs with a strong focus on HCI, which use problem based learning (PBL) as a teaching methodology. We describe a novel education called Medialogy, developed at Aalborg University Copenhagen in Denmark, outlining through different case studies how PBL supports transdisciplinarity.
Instability Analysis of a Three-Port Network

An analytical approach to unconditional and conditional instabilities of a three-port network is presented herein. This approach begins with inequality expressions of the input reflection coefficients Γ<sub>in</sub> and Γ<sub>out</sub> of a three-port network defined at ports 1 and 2 having port 3 terminated with load Γ<sub>3</sub>. The requirements of the conditional instabilities are derived to show that there is a largest conditional instability region in the Γ<sub>3</sub> -plane as ports 1 and 2 are terminated with the matched loads. Then the explicit expressions are derived for the boundary of the conditional instability region and the maximum instability curves in the Γ<sub>3</sub>-plane to lead one to properly select the Γ<sub>3</sub> value or design the terminating network at port 3. For the selected Γ<sub>3</sub> value, the conditional instability regions in the Γ<sub>1</sub>- and Γ<sub>2</sub>-planes are also given for the design consideration of the loads at ports 1 and 2. In order to fully characterize the instability of a three-port network, the similar procedure can be conducted by treating port 1 or port 2 as the terminating network. The resulting instability expressions not only provide useful design equations but also are implemented in Agilent Advanced Design System software to enhance its computer-aided capability of the instability analysis of a three-port network, especially the microwave oscillator.
The Greening after Extended Darkness1 Is an N-End Rule Pathway Mutant with High Tolerance to Submergence and Starvation1[OPEN]

An E3 ligase PRT6 mutant with constitutive expression of hypoxic genes confers tolerance against submergence via sugar conservation as well as resistance to starvation. Plants respond to reductions in internal oxygen concentrations with adaptive mechanisms (for example, modifications of metabolism to cope with reduced supply of ATP). These responses are, at the transcriptional level, mediated by the group VII Ethylene Response Factor transcription factors, which have stability that is regulated by the N-end rule pathway of protein degradation. N-end rule pathway mutants are characterized by a constitutive expression of hypoxia response genes and abscisic acid hypersensitivity. Here, we identify a novel proteolysis6 (prt6) mutant allele, named greening after extended darkness1 (ged1), which was previously discovered in a screen for genomes uncoupled-like mutants and shows the ability to withstand long periods of darkness at the seedling stage. Interestingly, this ethyl methanesulfonate-derived mutant shows unusual chromosomal rearrangement instead of a point mutation. Furthermore, the sensitivity of N-end rule pathway mutants ged1 and prt6-1 to submergence was studied in more detail to understand previously contradicting experiments on this topic. Finally, it was shown that mutants for the N-end rule pathway are generally more tolerant to starvation conditions, such as prolonged darkness or submergence, which was partially associated with carbohydrate conservation.
The role of serious mental illness in motivation, participation and adoption of health behavior change among obese/sedentary Latino adults

ABSTRACT Objective: Serious mental illness (SMI; e.g. schizophrenia, schizoaffective disorder, delusional disorder, bipolar disorder, severe major depressive disorder, and psychotic disorders) and Latino ethnicity can produce a compounded health disparity, placing individuals at particularly high risk for excess morbidity and premature mortality. In this study we sought to identify the role of SMI in motivation, participation, and adoption of health behavior change among overweight Latino adults. Design: Qualitative, semi-structured interviews were conducted with 20 overweight Latinos with SMI who were enrolled in a randomized trial evaluating the effectiveness of a motivational health promotion intervention adapted for persons with SMI, In SHAPE. The interviews explored the complicated role having an SMI had in the lives of the Latino participants. Results: SMI had both positive and negative impact on Latino participants’ health behaviors. The nature of their mental illness along with medication side effects (e.g. lethargy, weight gain, etc.) negatively impacted their ability to making lasting health behavior change. However, the regular appointments with various specialists provided them with structure that they otherwise would have lacked and gave them a reason to get out of the house. Conclusions: This exploratory research provides insight into the experience of overweight Latinos with SMI and the ways in which SMI impacts their participation in health behavior change. An understanding of the positive and negative effects of SMI on health behavior change will inform the development of health promotion interventions targeted at Latinos with SMI.
Experimental comparison of photogrammetry for additive manufactured parts with and without laser speckle projection

In this paper we show that, by using a photogrammetry system with and without laser speckle, a large range of additive manufacturing (AM) parts with different geometries, materials and post-processing textures can be measured to high accuracy. AM test artefacts have been produced in three materials: polymer powder bed fusion (nylon-12), metal powder bed fusion (Ti-6Al-4V) and polymer material extrusion (ABS plastic). Each test artefact was then measured with the photogrammetry system in both normal and laser speckle projection modes and the resulting point clouds compared with the artefact CAD model. The results show that laser speckle projection can result in a reduction of the point cloud standard deviation from the CAD data of up to 101 μm. A complex relationship with surface texture, artefact geometry and the laser speckle projection is also observed and discussed.
Mean likelihood and higher order approximations

SUMMARY Higher order approximations to p-values can be obtained from the log-likelihood function and a supplementary function that can be viewed as a canonical parameter in an exponential family approximation to the model. This approach clarifies the connection between various approximations proposed in the literature, and in particular makes transparent the link between the approach suggested in Skovgaard (1996) and Fraser et al. (1999a). 1. INTRODUCTION Parametric likelihood inference is often based on first order approximations to standard summary statistics from the likelihood, such as the likelihood ratio statistic or the standardized maximum likelihood estimate. For more accurate inference refinements are needed to both improve the first order approximation of the distribution of the relevant statistic, and to properly take account of nuisance parameters, in the multi-parameter setting. A great many examples are available that illustrate the failure of first-order methods in models with large numbers of nuisance parameters, and there is a similar wealth of examples illustrating the accuracy of higher order approximations. In this note we establish a very simple connection between the higher order approximation due to Skovgaard (1996) and that of Fraser et al. (1999a), which also leads to quite direct connections with the approximations of Barndorff-Nielsen (1986) and Severini (1998). This connection is established by emphasizing the role of exponential family models as approximations to the original model, in obtaining higher order approximations for parametric inference. The canoni-cal parameters of these families are discussed in §2, with the tail area approximations developed from them presented in §3. In §4 we consider several examples, and §5 discusses some extensions suggested by these connections.
Simulations of 3 D non-hydrostatic free surface flows with SPH

In this paper, the application of a new robust and accurate SPH scheme proposed by Ferrari et al. [1] is presented. It provides good accuracy for computing complex 3D non-hydrostatic free surface flows. This has been assesed by the comparison of the numerical solutions of dam-break and impact-wave problems against experimental data and reference solutions. Moreover, to improve considerably the computational efficiency the parallelization of the code has been carried out in order to run simulations involving millions of particles on modern massively parallel supercomputers. Thanks to the access to the infrastructure provided by HLRS in Stuttgart in the framework of the HPC-Europa Program, the author could perform applications of large scale flow problems. A very satisfactory agreement and results have been obtained.
Liquimedia | a Dynamically Extensible Cyclic Executive

Because it involves theoretical latencies that are unbounded, and practical latencies that are large, dynamic resource allocation poses di cult problems for all real-time systems. Control applications, where the task environment and range of possible computations are both highly constrained, can solve this problem using static allocation, with all allocation occurring outside of the realtime constraints. This simple and reliable strategy is unsuited to multimedia systems, however, because they must operate successfully in extremely variable computational environments. The solution is to create a version of dynamic allocation that retains the essence of the static solution, while taking advantage of characteristics unique to multimedia. This paper discusses using this strategy for allocation of computation and communication. CPU cycles and network bandwidth are the most basic resources used in any computation. We believe that a clean abstraction that is successful with these resources will certainly extend to other resources such as input and output devices. We believe that current operating systems designed for multimedia cannot allocate computational resources at a su ciently small granularity. Current general purpose operating systems allocate a processor's time with threads. Even on the fastest systems, context switches result in delays of tens of microseconds. As a result, using the processor e ciently requires task durations a millisecond or longer. Common tasks for a multimedia operating system such as synthesizing positionalized sound or animating sprites take far less than a millisecond for each iteration. Consequently, a multimedia operating system must provide an alternative to threads for the allocation of processor time. We call our alternative performers. Performers discard the overhead of context switching by abandonning preemption. They must always yield the processor voluntarily. Forcing programmers to statically divide the application into groups of performers makes the same tradeo as a cyclic executive: additional development work in exchange for no runtime resource allocation overhead. This tradeo engenders a new problem. Unlike a traditional xed-functionality cyclic executive, a multimedia operating system needs the capability of dynamically altering which performers it's executing. Maintaining realtime execution of performers requires that the operating system attempt to execute only per-
Ergodic Theory Meets Polarization. I: An Ergodic Theory for Binary Operations

An open problem in polarization theory is to determine the bi nary operations that always lead to polarization when they are used in Arıkan-like constructions. This paper , which is presented in two parts, solves this problem by providing a necessary and sufficient condition for a binar y operation to be polarizing. This (first) part of the paper introduces the mathematical framework that we will us e in the second part [1] to characterize the polarizing operations: uniformity-preserving, irreducible, ergodi c and strongly ergodic operations are defined. The concepts of a stable partition and the residue of a stable partition ar e introduced. We show that an ergodic operation is strongly ergodic if and only if all its stable partitions are their own residues. We also study the products of binary operations and the structure of their stable partitions. We show that the product of a sequence of binary operations is strongly ergodic if and only if all the operations in the se qu nce are strongly ergodic. In the second part of the paper, we provide a foundation of polarization theory based on the ergodic theory of binary operations that we develop in this part.
Feedback Heating in Cluster and Galactic Cooling Flows

Cluster cooling flow models that include both active galactic nuclei (AGN) heating and thermal conduction can reduce the overall mass cooling rate and simultaneously sustain density and temperature profiles similar to those observed. These computed flows have no ad hoc mass dropout. To achieve this agreement, the thermal conductivity must be about 0.35 ± 0.10 times the Spitzer value, similar to that advocated by Narayan & Medvedev. However, when applied to galaxy/group scales, the synergistic combination of AGN heating and conduction is less satisfactory. When the computed density profile and the global cooling rate are lowered by AGN heating to match observations of these smaller scale flows, the gas temperatures within ~10 kpc are too large. In addition, best-fitting flows in galaxy/groups with AGN heating and thermal conduction require conductivities much closer to the Spitzer value, ~0.5-1. Another difficulty with galaxy/group flows that combine AGN heating and conduction is that the iron enrichment by Type Ia supernovae is more effective when the gas density is lowered by heating to match the observations. The hot-gas iron abundance in galactic flows with heating and conduction greatly exceeds observed values throughout most of the galaxy. Galactic/group flows with central heating and conduction, therefore, require an additional process that removes the iron: failure of Type Ia supernovae ejecta to go into the hot phase, selective cooling, etc.
Case study: implementing a web based auction system using UML and component-based programming

This paper presents a case study highlighting the best practices for designing and building a web-based auction system using UML (Unified Model Language) and component-based programming. We use the Use Case, Class, Sequence, and Component Diagrams offered by UML for designing the system. This enables new functions to be added and updated easily. Our implementation, with its basis in component-based programming, enabled us to develop a highly maintainable system with a number of reusable components: the Method of Bidding (the bidder can bid at three different frequencies-fast, medium or leisurely), the Certification (Identity verification function), and the Registration Good (Product entry function) Components. Further, the system uses intelligent agents that permit fair help to bidders participating in auctions and at the same time achieve maximum profit for the seller. The design and implementation environment, along with the tools used, provide excellent support for the successful development of the system.
