Roles of the NFk B Pathway in Lymphocyte Development and Function

This article focuses on the functions of NF-kB that vitally impact lymphocytes and thus adaptive immunity. NF-kB has long been known to be essential for many of the responses of mature lymphocytes to invading pathogens. In addition, NF-kB has important functions in shaping the immune system so it is able to generate adaptive responses to pathogens. In both contexts, NF-kB executes critical cell-autonomous functions within lymphocytes as well as within supportive cells, such as antigen-presenting cells or epithelial cells. It is these aspects of NF-kB’s physiologic impact that we address in this article.
An Interaction between Exercise Order and Rest Interval during Lower-Body Resistance Exercise

Background: The purpose of the present study was to compare the influence of twoand fiveminute rest intervals on the number of repetitions per set and total repetitions per exercise for a lower-body workout performed in 2 different sequences. Material/Methods: 12 resistance trained men completed 4 experimental resistance exercise sessions. All sessions consisted of 3 sets with a 10-repetition maximum load for 4 lower-body exercises. Two different exercise sequences (i.e., A or B) were performed with either 2or 5minute rest between the sets and the exercises, respectively. The order of exercises for sequence A2 (SEQA2) and sequence A5 (SEQA5) was squat, leg curl, leg extension, and calf raise with 2and 5-minute rest intervals between the sets and the exercises respectively. Conversely, for sequence B2 (SEQB2) and sequence B5 (SEQB5), the exercises were performed in the opposite order. Results: The results demonstrated a significant decrease from set 1 to set 2 in 3 exercises for SEQA2 and 2 exercises for SEQB2; from set 1 to set 3 in all exercises for SEQA2 and SEQB2, 3 exercises for SEQA5, and 2 exercises for SEQB5; and from set 2 to set 3 in 3 exercises for SEQA2, 2 exercises for SEQB2, and 1 exercise for SEQB5 (p<0.05). In addition, the total number of completed repetitions was significantly different (p<0.05) between sequences for squat (SEQA5 > SEQA2 > SEQB5 > SEQB2), leg curl (SEQA5 = SEQB5 > SEQA2 = SEQB2), leg extension (SEQA5 = SEQB5 = SEQB2 > ASEQA2), and calf raise (SEQB5 > SEQB2 = SEQA5 > SEQA2). Conclusions: The results indicate that during a lower-body workout reductions in the number of repetitions are greater for exercises performed at the end of the sequences, and the influence of the different rest interval lengths may depend on the position of the exercise in a sequence.

Gait and Postural Sway Analysis, A Multi-Modal System

Detecting a fall before it actually happens will positively affect lives of the elderly. While the main causes of falling are related to postural sway and walking, determining abnormalities in one of these activities or both of them would be informative to predicting the fall probability. A need exists for a portable gait and postural sway analysis system that can provide individuals with real-time information about changes and quality of gait in the real world, not just in a laboratory. In this research project I aim to build a multi-modal system that finds the correlation between vision extracted features and accelerometer and force plate data to determine a general gait and body sway pattern. Then this information is used to assess a difference to normative age and gender relevant patterns as well as any changes over time. This could provide a core indicator of broader health and function in ageing and disease.
Coordinated task manipulation by nonholonomic mobile robots

Coordinated task manipulation by a group of autonomous mobile robots has received significant research effort in the last decade. Previous studies in the area revealed that one of the main problems in the area is to avoid the collisions of the robots with obstacles as well as with other members of the group. Another problem is to come up with a model for successful task manipulation. Significant research effort has accumulated on the definition of forces to generate reference trajectories for each autonomous mobile robots engaged in coordinated behavior. If the mobile robots are nonholonomic, this approach fails to guarantee successful manipulation of the task since the so-generated reference trajectories might not satisfy the nonholonomic constraint. In this work, we introduce a novel coordinated task manipulation model inclusive of an online collision avoidance algorithm. The reference trajectory for each autonomous nonholonomic mobile robot is generated online in terms of linear and angular velocity references for the robot; hence these references automatically satisfy the nonholonomic constraint. The generated reference velocities inevitably depend on the nature of the specified coordinated task. Several coordinated task examples, on the basis of a generic task, have been presented and the proposed model is verified through simulations
Responsabilité économique et sociale des concepteurs de systèmes d'information: contribution à une éthique appliquée

This article deals with the moral responsibility of information systems designers, in the context of professional use. In the exercise of this moral responsibility, economic and social dimensions will be specifically discussed here, in the sense that SI have an impact on the development and sustainability of organizations.The first part of this article is devoted to a state of the art on computer ethics. A second part presents our orientation (critical research) and our approach (which considers information systems as power devices), and concludes on the need to think an engineering of responsibility. In the third part, our contribution to this engineering is exposed in the form of a three-level model, which helps to reveal how a general vision and linked ethical values are gradually embodied in structuring principles, and binding standards.

The design and validation of the R1 personal humanoid

In recent years the robotics field has witnessed an interesting new trend. Several companies started the production of service robots whose aim is to cooperate with humans. The robots developed so far are either rather expensive or unsuitable for manipulation tasks. This article presents the result of a project which wishes to demonstrate the feasibility of an affordable humanoid robot. R1 is able to navigate, and interact with the environment (grasping and carrying objects, operating switches, opening doors etc). The robot is also equipped with a speaker, microphones and it mounts a display in the head to support interaction using natural channels like speech or (simulated) eye movements. The final cost of the robot is expected to range around that of a family car, possibly, when produced in large quantities, even significantly lower. This goal was tackled along three synergistic directions: use of polymeric materials, light-weight design and implementation of novel actuation solutions. These lines, as well as the robot with its main features, are described hereafter.
ULTRASTRUCTURAL CHANGES IN RAT TESTICULAR TISSUE AFTER WHOLE BODY EXPOSURE TO ELECTROMAGNETIC RADIATION EMITTED FROM MOBILE PHONES

The possible adverse reproductive effects resulting from exposure to electromagnetic fields (EMF) are currently of great public concern. The objective of the present study is to reveal possible effects of electromagnetic fields emitted from a CDMA mobile phone on the ultrastructural aspects of the testicular cells. Approximately 6 weeks old Swiss albino rats were procured from LLRUVAS, Hisar, Haryana. Rats were acclimatized in plastic cages in a room maintained at 24 ± 1 o C and 50 ± 5 % humidity with an alternating 12 h light-darkness cycle. After one week, rats were exposed under electromagnetic radiation emitted from a CDMA mobile phone with 3 hrs exposure followed by 30 minutes rest and then again 3 hrs exposure per day for five months. One sham group was kept away from the source of radiation and was used as control for the experimental groups. Immediately after the last irradiation, rats were sacrificed and their testes were analyzed using Electron Microscopic techniques. Studies revealed pycnotic nuclei in germ cells, vacuolization in spermatogenic cells and detachment of spermatogonia and sertoli cells from basal lamina. Shrinkage was induced on the surface of the seminiferous epithelium due to exposure. Residual cytoplasm and debris of degenerating cells were also observed in the seminiferous tubules.
Outcome of accelerated radiotherapy alone or accelerated radiotherapy followed by exenteration of the nasal cavity in dogs with intranasal neoplasia: 53 cases (1990-2002).

OBJECTIVE To compare long-term results of radiotherapy alone versus radiotherapy followed by exenteration of the nasal cavity in dogs with malignant intranasal neoplasia. DESIGN Retrospective study. ANIMALS 53 dogs with malignant intranasal neoplasia. PROCEDURE All dogs underwent radiotherapy consisting of administration of 10 fractions of 4.2 Gy each on consecutive weekdays. For dogs in the surgery group (n=13), follow-up computed tomography was performed, and dogs were scheduled for surgery if persistent or recurrent tumor was seen. RESULTS Perioperative complications for dogs that underwent surgery included hemorrhage requiring transfusion (2 dogs) and subcutaneous emphysema (8). Rhinitis and osteomyelitis-osteonecrosis occurred significantly more frequently in dogs in the radiotherapy and surgery group (9 and 4 dogs, respectively) than in dogs in the radiotherapy-only group (4 and 3 dogs, respectively). Two- and 3-year survival rates were 44% and 24%, respectively, for dogs in the radiotherapy group and 69% and 58%, respectively, for dogs in the surgery group. Overall median survival time for dogs in the radiotherapy and surgery group (477 months) was significantly longer than time for dogs in the radiotherapy-only group (19.7 months). CONCLUSIONS AND CLINICAL RELEVANCE Results suggest that exenteration of the nasal cavity significantly prolongs survival time in dogs with intranasal neoplasia that have undergone radiotherapy. Exenteration after radiotherapy may increase the risk of chronic complications.
Genome-Wide Survey of Human Alternative Pre-mRNA Splicing with Exon Junction Microarrays

Alternative pre–messenger RNA (pre-mRNA) splicing plays important roles in development, physiology, and disease, and more than half of human genes are alternatively spliced. To understand the biological roles and regulation of alternative splicing across different tissues and stages of development, systematic methods are needed. Here, we demonstrate the use of microarrays to monitor splicing at every exon-exon junction in more than 10,000 multi-exon human genes in 52 tissues and cell lines. These genome-wide data provide experimental evidence and tissue distributions for thousands of known and novel alternative splicing events. Adding to previous studies, the results indicate that at least 74% of human multi-exon genes are alternatively spliced.
ANN-based short-term load forecasting in electricity markets

This paper proposes an artificial neural network (ANN)-based short-term load forecasting technique that considers electricity price as one of the main characteristics of the system load, demonstrating the importance of considering pricing when predicting loading in today's electricity markets. Historical load data from the Ontario Hydro system as well as pricing information from the neighboring system are used for testing, showing the good performance of the proposed method.
The Precision of Query Points as a Resource for Learning Convex Polytopes with Membership Queries

We consider the problem of learning convex polytopes from membership queries only, where the learner is initially provided with a single interior point. The class of polytopes learnable in this setting turns out to be those whose vertices can be eeciently enumerated given their bounding hyperplanes. It is an open question whether in general one can enumerate the vertices of a given polytope in time polynomial in the number of vertices. In fact, we show that both problems are equivalent. We also give a query-based algorithm for the related problem of piecewise linear function regression. The bit complexity of the instances in our queries and the time complexity are polynomial in the bit complexity of the coeecients of the equations deening the bounding hyper-planes. This is consistent with prior established results showing that the weights, not the size, of a neural network determine the complexity of learning. As in previous positive results on learning convex polytopes, the precision of the instances queried can havèpolynomially' high precision. Thus one can view the precision of the input to the membership query oracle as a useful resource. This leads us to investigate learning environments where this precision is limited.
Paradigms in corporate ethics: the legality and values of corporate ethics

Purpose - It has always been claimed that business ethics are ambiguous and thus hard to define. As such, with recognizable unethical corporate behaviors as an epidemic, it is hard to hold perpetrators accountable. Even more detrimental are the miscommunication, the misunderstanding, the misinterpretation, and the misuse of the various paradigms in business ethics. Such flawed values and legality of business ethics paradigms cannot persist. There exist a gap and a bridging in the analysis of the paradigms in business ethics between the practitioners and the ethicists. This paper aims to provide an elaborate analysis of the values, trust, and legality of corporate behaviors in business ethics utilizing various paradigms. Design/methodology/approach - The analysis of this paper focused on the founding values and legality of business ethics and the underlying paradigms that practitioners and ethicists adopt. Findings - The limitation of this study is that the probability of the diverse schools of thought intertwining is smaller than that their coexisting. Originality/value - It is this coexistence of schools of thought that makes corporate USA humane, civilized, and balanced. Thus, to maintain this coexistence, if not improve it, this paper maintains that practitioners of higher education and corporate USA must take responsibility in training, educating, and producing future ethical business practitioners.
Innovation Co-Creation in a Virtual World

The emergence of web-based technologies has radically influenced the ways in which individuals around the world communicate, represent themselves, share ideas, and otherwise interact with one another (Ward and Sonneborn, 2009; Rogers, 2003). In particular, these technologies allow people to communicate directly with one another and to share and shape their own experiences; as a result, customers and other organisational stakeholders are increasingly involved in the design of products and services (Ramaswamy and Gouillart, 2010, p. 102). During innovation co-creation specifically, customers take an active and creative role in the intentional and successful adoption and application of ideas, processes, products or procedures that are new to the adopting organization. This study carries out six case studies of innovation co-creation in the virtual world of Second Life. Virtual worlds allow users to engage in highly active and participatory forms of co-creation that are difficult if not impossible to replicate in other environments. The study explores collaborative processes used for innovation co-creation in virtual worlds. In particular, the study presents an analysis of behaviours used to facilitate innovation co-creation in virtual world projects and the factors that affect it. The study leverages this analysis to derive practical recommendations for virtual world users and virtual world designers that can be used to stimulate and support innovation co-creation in virtual worlds.
Cognitive exploration of regions through analyzing geo-tagged social media data

Social media has now become a pervasive global communication channel. Many applications and platforms have become available for users to post messages, follow friends and share experiences. Due to the high frequency with which users update their states, a large amount of data is being generated around the world every second. By analyzing this data, valuable patterns can be extracted such as the distribution of users, their common interests, activities, locations visited, etc. In this paper, we focus on the cognitive exploration of photo sharing data. Traditionally, each photo sharing record comes with information about the location where the photo was taken, a timestamp, and potentially some description about the photo. Therefore, we can often deduce the features of photo-spots. Spots with similar features constitute a region of cognitive interest. The primary goal of this paper is to identify these regions and allow users to explore into regions of interest by cognitive understanding of their features and patterns of feature propagation in time. To achieve this goal, we propose an approach that makes use of semantic analysis in big data sets, data clustering, and cognitive visualization design issues. Our contributions are two-fold. First, we put forward a novel social-media data classification method. This is based on cognitive semantic analysis. Second, we suggest a new method to explore social activity maps by discovering regions of cognitive interest. In this paper, we introduce the design of an interactive visualization interface which projects photo sharing data to cognitive social activity map components. Experiments are performed on the Flickr dataset.
Collaboration as a learning challenge: Constructing a common understanding between police officers and tax inspectors

Collaboration across organizational boundaries has been promoted in Finland to control economic crimes more efficiently. However, the organizational tasks and goals of the participating authorities diverge and the traditions of individual work are strong within each authority. Constructing the collaborative investigation process, as well as a common understanding about the crime under investigation, are seen as learning challenges. This paper describes how these challenges are met in practice, in a meeting in which the collaboration between the police and tax authority was commenced in a tax-crime case. The underlying tensions emerge as disagreements and consolidation of boundaries between activity systems but also as attempts to find a shared view and as boundary crossings. The diverse orientations and tensions between activity systems are seen as an energy source for potential expansive learning about new forms of activity as they are being created.
A Nitrogen Response Pathway Regulates Virulence Functions in Fusarium oxysporum via the Protein Kinase TOR and the bZIP Protein MeaB[C][W]

Nitrogen limitation has been proposed to act as a signal for infectious development in plant pathogens. Here, the authors show that the preferred nitrogen source ammonium represses a set of virulence-related functions in the vascular wilt fungus Fusarium oxysporum. They also identify two key elements of the nitrogen response pathway: the conserved protein kinase TOR and the bZIP factor MeaB. During infection, fungal pathogens activate virulence mechanisms, such as host adhesion, penetration and invasive growth. In the vascular wilt fungus Fusarium oxysporum, the mitogen-activated protein kinase Fmk1 is required for plant infection and controls processes such as cellophane penetration, vegetative hyphal fusion, or root adhesion. Here, we show that these virulence-related functions are repressed by the preferred nitrogen source ammonium and restored by treatment with l-methionine sulfoximine or rapamycin, two specific inhibitors of Gln synthetase and the protein kinase TOR, respectively. Deletion of the bZIP protein MeaB also resulted in nitrogen source–independent activation of virulence mechanisms. Activation of these functions did not require the global nitrogen regulator AreA, suggesting that MeaB-mediated repression of virulence functions does not act through inhibition of AreA. Tomato plants (Solanum lycopersicum) supplied with ammonium rather than nitrate showed a significant reduction in vascular wilt symptoms when infected with the wild type but not with the ΔmeaB strain. Nitrogen source also affected invasive growth in the rice blast fungus Magnaporthe oryzae and the wheat head blight pathogen Fusarium graminearum. We propose that a conserved nitrogen-responsive pathway might operate via TOR and MeaB to control virulence in plant pathogenic fungi.
Study on Rotational Hysteresis and Core Loss Under Three-Dimensional Magnetization

In this paper, magnetic properties of soft magnetic composite (SMC) materials under alternating and various rotational magnetizations have been properly measured, modeled, and analyzed at typical frequencies of 5, 50, and 500 Hz. The relationship between the magnetic flux density vector B and magnetic field strength vector H has been systemically studied when the B loci are well controlled to be circles and ellipses in three orthogonal planes of the three-dimensional (3-D) tester. The core loss features against magnetic flux densities with alternating and rotational magnetizations are also compared and analyzed. It is found that the rotational core losses are nearly twice of the alternating core losses at the same magnitude of flux density. Experimental results show that SMC materials have good 3-D features, and great potential for application in rotational magnetic flux machines.
Multiverse: Easy Conversion of Runtime Systems into OS Kernels via Automatic Hybridization

The hybrid runtime (HRT) model offers a path towards high performance and efficiency. By integrating the OS kernel, runtime, and application, an HRT allows the runtime developer to leverage the full feature set of the hardware and specialize OS services to the runtime's needs. However, conforming to the HRT model currently requires a port of the runtime to the kernel level, for example to the Nautilus kernel framework, and this requires knowledge of kernel internals. In response, we developed Multiverse, a system that bridges the gap between a built-from-scratch HRT and a legacy runtime system. Multiverse allows unmodified applications and runtimes to be brought into the HRT model without any porting effort whatsoever by splitting the execution of the application between the domains of a legacy OS and an HRT environment. We describe the design and implementation of Multiverse and illustrate its capabilities using the massive, widely-used Racket runtime system.
