Effect of Peripheral Afferent Alteration of the Lateral Ankle Ligaments on Dynamic Stability *

Background The sensorimotor influence of the lateral ankle ligaments in muscle activation is unclear. Hypothesis The lateral ankle ligaments have significant sensorimotor influence on muscle activation. Study Design Controlled laboratory study. Methods Muscle-firing characteristics in response to a high-speed inversion perturbation and during gait were assessed in 13 normal subjects. Solutions (1.5% lidocaine or a placebo of saline) were injected bilaterally into the anterior talofibular and calcaneofibular ligaments (1.5 ml per ligament) to alter peripheral afferent influence. Subjects were again tested with the same protocol. Results The protective response of the anterior tibialis and peroneal muscles during inversion perturbation and mean muscle activation amplitude decreased during running after both injections. After injection, no significant differences were seen for muscle reflex latencies, maximum amplitude, time to maximum amplitude during inversion perturbation, or mean amplitude during walking. Conclusion The lateral ankle ligaments have a sensorimotor influence on muscle activation. Clinical Relevance Induced edema from the injected solutions may have altered the sensorimotor influence of the lateral ankle ligaments, thereby inhibiting the dynamic ankle stabilizers. This finding suggests that dynamic stability may be compromised because of swelling after joint injury.
Diagnosis of Hepatic Veno-occlusive Disease by Plasminogen Activator Inhibitor-1 Plasma Antigen Levels: A Prospective Analysis in 350 Allogeneic Hematopoietic Stem Cell Recipients

Background. Veno-occlusive disease (VOD) is one of the most serious complications following allogeneic hematopoietic stem cell transplantation (HSCT) and is associated with a high mortality. We conducted a large trial in order to investigate the value of plasminogen activator inhibitor-1 (PAI-1) plasma antigen levels in VOD patients as PAI-1 has been described as a possible diagnostic marker of VOD. Methods. In all, 350 stem cell recipients were included in our study. PAI-1 levels were analyzed prior to conditioning therapy and then weekly until eight weeks after HSCT. Transplantation-related complications (TRC) including VOD, microangiopathic hemolytic anemia (MAHA), and graft-versus-host disease (GVHD) were recorded weekly throughout the study. Results. Maximum PAI-1 antigen levels were increased in all patients with VOD (n=15; mean 248 ng/ml; 95% CI 183–314 ng/ml). Maximum PAI-1 levels above 120 ng/ml showed a sensitivity of 100% and a specificity of 30.6% for VOD after HSCT. Conclusion. Our study underlines that maximum PAI-1 plasma antigen levels not exceeding 120 ng/ml have a strong negative predictive value in the diagnosis of VOD and thus represent a helpful non-invasive tool for exclusion of VOD after HSCT.
Experimental evaluation of distributed middleware with a virtualized Java environment

The correctness and performance of large scale service oriented systems depend on distributed middleware components performing various communication and coordination functions. It is, however, very difficult to experimentally assess such middleware components, as interesting behavior often arises exclusively in large scale settings, but such deployments are costly and time consuming. We address this challenge with Minha, a system that virtualizes multiple JVM instances within a single JVM while simulating key environment components, thus reproducing the concurrency, distribution, and performance characteristics of the actual system. The usefulness of Minha is demonstrated by applying it to the WS4D Java stack, a popular implementation of the Devices Profile for Web Services (DPWS) specification.
Identification and expression profiling analysis of calmodulin-binding transcription activator genes in maize (Zea mays L.) under abiotic and biotic stresses

The calmodulin-binding transcription activators (CAMTA) play critical roles in plant growth and responses to environmental stimuli. However, how CAMTAs function in responses to abiotic and biotic stresses in maize (Zea mays L.) is largely unknown. In this study, we first identified all the CAMTA homologous genes in the whole genome of maize. The results showed that nine ZmCAMTA genes showed highly diversified gene structures and tissue-specific expression patterns. Many ZmCAMTA genes displayed high expression levels in the roots. We then surveyed the distribution of stress-related cis-regulatory elements in the −1.5 kb promoter regions of ZmCAMTA genes. Notably, a large number of stress-related elements present in the promoter regions of some ZmCAMTA genes, indicating a genetic basis of stress expression regulation of these genes. Quantitative real-time PCR was used to test the expression of ZmCAMTA genes under several abiotic stresses (drought, salt, and cold), various stress-related hormones [abscisic acid, auxin, salicylic acid (SA), and jasmonic acid] and biotic stress [rice black-streaked dwarf virus (RBSDV) infection]. Furthermore, the expression pattern of ZmCAMTA genes under RBSDV infection was analyzed to investigate their potential roles in responses of different maize cultivated varieties to RBSDV. The expression of most ZmCAMTA genes responded to both abiotic and biotic stresses. The data will help us to understand the roles of CAMTA-mediated Ca2+ signaling in maize tolerance to environmental stresses.
Reading the riots: what were the police doing on Twitter?

The widespread adoption of new forms of digital communication platforms such as micro-blogging sites presents both an opportunity and a challenge for researchers interested in understanding people's attitudes and behaviours, especially in the context of unfolding crises and the need for government agencies such as the police to inform the public and act swiftly to ensure public order and safety. In this paper, we use a study of a recent public order crisis in England to explore how the police, other organisations and individuals used Twitter as they responded to this event.
The How , When and Why of Sentiment Analysis

With the explosive growth of social media on web ,individuals and organizations are increasingly using the content in these media for decision making. Nowadays if one wants to buy a consumer product one prefer user reviews and discussion in public forums on web about the product.As a result opinion mining has gained importance. This online -word-of-mouth represent new and measurable source of information with many applications, this process of identifying and extracting subjective information from raw data is known as sentiment analysis. This paper presents a survey on sentiment analysis or opinion mining. The existing literature of opinion mining is explained in detail. We explore the application oriented approach and discussed various domain where opinion mining would be useful. Finally we put forward research challenges in this field.
Extended expedited forwarding: the in-time PHB group

This paper presents a new set of forwarding behaviors that fits rate-adaptive and delay-sensitive applications with limited loss tolerance. We consider an application to have limited loss tolerance if it needs loss-free forwarding of specific packets up to a certain rate. The new set of forwarding behaviors are attractive for developing real-time applications for the Internet. In particular, such applications can be designed to use reserved forwarding capacity efficiently and compete for more bandwidth while being fair to best-effort traffic. To provide the new set of forwarding behaviors, we define a scheduling mechanism that can be implemented efficiently. Through simulations, we show that this mechanism supports the defined forwarding behaviors.
Xanthones from fungi, lichens, and bacteria: the natural products and their synthesis.

Many fungi, lichens, and bacteria produce xanthones (derivatives of 9H-xanthen-9-one, “xanthone” from the Greek “xanthos”, for “yellow”) as secondary metabolites. Xanthones are typically polysubstituted and occur as either fully aromatized, dihydro-, tetrahydro-, or, more rarely, hexahydro-derivatives. This family of compounds appeals to medicinal chemists because of their pronounced biological activity within a notably broad spectrum of disease states, a result of their interaction with a correspondingly diverse range of target biomolecules. This has led to the description of xanthones as “privileged structures”. (1) Historically, the total synthesis of the natural products has mostly been limited to fully aromatized targets. Syntheses of the more challenging partially saturated xanthones have less frequently been reported, although the development in recent times of novel and reliable methods for the construction of the (polysubstituted) unsaturated xanthone core holds promise for future endeavors. In particular, the fascinating structural and biological properties of xanthone dimers and heterodimers may excite the synthetic or natural product chemist.
Kalman filter design for application to an INS analysing swimmer performance

Performance analysis is essential for the ongoing development of elite swimmers. Current methods of analysis do not provide the coach with an accurate system for determining a swimmer's position. This research was conducted to allow transmission, processing and presentation of the swimmer's attitude, velocity and position. A Kalman filter was integrated into a wireless system to track these parameters.
Subverting the Xen hypervisor

This paper outlines the recent work by the author to design and develop a backdoor for machines running the Xen hypervisor. An attacker can gain backdoor control over the host by overwriting Xen code and data structures; as not a single byte in dom0 domain is modified, the detection of such a backdoor is difficult if conducted from within dom0. It is shown that it is feasible to modify device drivers and core kernel code to conveniently conduct DMA to arbitrary physical address, which allows for control over the hypervisor. Two backdoors have been implemented: one resides in the hypervisor code, the other resides in a hidden domain with artificially elevated privileges.
Memcached Integration with Twister

— MapReduce programming model has proven its value in the domain of large scale data analysis since the introduction by Google. Twister extends this model efficiently with its support for iterative MapReduce with streaming data transfer via publish/subscribe messaging. This efficiency is challenged recently with applications requiring large chunks of data transfer. We propose having a unified memory access layer across Twister nodes instead of a publish/subscribe broker as a viable solution. The implementation integrates the open source Memcached, a distributed memory caching system, with Twister. We expect to get comparable performance results on this approach against current Twister implementation. We also plan to compare performance on our implementation with another proposed solution, which uses RPC messaging with Twister.
Global sea level linked to global temperature

We propose a simple relationship linking global sea-level variations on time scales of decades to centuries to global mean temperature. This relationship is tested on synthetic data from a global climate model for the past millennium and the next century. When applied to observed data of sea level and temperature for 1880–2000, and taking into account known anthropogenic hydrologic contributions to sea level, the correlation is >0.99, explaining 98% of the variance. For future global temperature scenarios of the Intergovernmental Panel on Climate Change's Fourth Assessment Report, the relationship projects a sea-level rise ranging from 75 to 190 cm for the period 1990–2100.
Arbitrary tilings of phase space

This paper considers the approximation of the continuous wavelet transform (CWT) for band-limited signals. We present a digital filter design technique to approximate the CWT on arbitrary lattices of points in the phase plane. Using compactly supported wavelets and smoothing functions (which approximate the sin/spl pi/t//spl pi/t scaling function), FIR filters are designed to compute the samples of the CWT directly from the sampled input data. This technique is compared to the discrete wavelet transform algorithm. <<ETX>>
Use of ℓ 2/3 -norm Sparse Representation for Facial Expression Recognition

In this particular paper, we recommend a brand new sparse rendering primarily based group via l2/3-norm minimization with regard to facial Expression Recognition. All of us work with l2/3-norm minimization instead of l2/3-norm minimization with regard to sparser, a lot more identification fee and many correct options, lowest computing moment and optimization dilemma connected with l2/3-norm minimization. This l2/3-norm regularize is actually open to get a wide range of ensuring components such as neutral, eye-sight and sparsity components. All of us work with l2/3-norm minimization (l2/3 SRC) as an alternative to l2/3-norm minimization (l2/3 SRC). Additionally, the active-set primarily based iterative reweighted criteria are actually recommended to fix your l2/3-Norm minimization dilemma. This trial and error effects with JAFFE Database/sources state your productivity connected with l2/3-SRC. latest evolution of l2/3-norm regularizer, we advise a latest SRC via l2/3-norm minimization in this paper. We show our technique by l2/3-SRC to discriminate it from the conventional SRC which is denoted by l1/2-SRC. In l2/3- SRC, we apply l2/3-norm minimization as an option to l1/2- norm minimization in its place of using l0-norm minimization in l1/2-SRC. By take on l2/3-norm minimization, we can locate minimum computation time, sparser and more precise solution than l2/3-SRC do and the optimization problem of l2/3-norm minimization is much easier to be solved than that of l1/2-norm minimization. The rest of the paper is organized as follows. Section II describes the proposed model in detail and presents an active set based iterative reweighted algorithm to solve the l2/3- norm minimization problem. We conduct the experiments in section III, and conclude this paper in section IV. 2. Sparse representation VIA L2/3 - norm minimization
Universal Temporal Data Languages

Temporal reasoning and temporal query languages present diicult research challenges , which are slowly yielding to the combined attack of many investigations motivated by the theoretical interest and practical import of the problem. In this paper, we subscribe to TSQL2 insofar as practical requirements for a query language are concerned, but we propose a solution that overcomes its shortcomings, particularly the lack of universality whereby TSQL2 temporal extensions can not be easily applied to other query languages, such as QBE and Datalog. In this paper, we use Datalog as a framework to develop a new language | Temporal Data Language (TDL). To support our claim of universality, we argue that TDL constructs and semantics can be directly applied to derive temporal extensions of languages, such as QBE and SQL. Finally, we evaluate alternative approaches to the implementation of TDL, using as the basis for implementation the LDL++ system with extended aggregates developed at UCLA.
Self-organization of spiking neurons using action potential timing

We propose a mechanism for unsupervised learning in networks of spiking neurons which is based on the timing of single firing events. Our results show that a topology preserving behavior quite similar to that of Kohonen's self-organizing map can be achieved using temporal coding. In contrast to previous approaches, which use rate coding, the winner among competing neurons can be determined fast and locally. Our model is a further step toward a more realistic description of unsupervised learning in biological neural systems. Furthermore, it may provide a basis for fast implementations in pulsed VLSI (very large scale integration).
Staff Support and Supervision in Residential Youth Justice: An Australian Model

The role for staff within the residential youth justice facility is an intense one, offering both reward and challenge. Post-traumatic stress related to serious episodes of violence and vicarious trauma relating to the abuse and neglect derived from the residents' personal narratives are common. In recent years a residential center in Melbourne, Victoria, Australia has experimented with provision of a Staff Support and Supervision Program (SSSP). This article describes the context which gave rise to the program, its multi-theoretical underpinning, and its modus operandi. A qualitative evaluation highlights practice challenges and leadership techniques. The model is now being applied in two other Victorian youth justice centers.
The Open Door Project Task Force: A Qualitative Study on LGBT Aging

This paper reports formative qualitative findings from the Open Door Project (ODP), a unique program created by the Lesbian, Gay, Bisexual and Transgender (LGBT) Aging Project. Data were collected from Open Door Task Force members (N = 34). This includes 4 focus groups that were held with a total of 22 participants; and key informant interviews that were conducted with 12 participants from 10 different agencies. Findings revealed that agencies took significant steps to make important and long-lasting structural changes, including changing their diversity and personnel policies, and intake forms to be LGBT inclusive; implementing ongoing staff training initiatives on LGBT issues; and actively involving leadership, including senior managers, executive directors, vendors, and Councils on Aging, in helping to create and sustain organizational change. The ODP is an effective model to increase cultural competence in working with aging LGBT communities.
Suppressing Glucose Transporter Gene Expression in Schistosomes Impairs Parasite Feeding and Decreases Survival in the Mammalian Host

Adult schistosomes live in the host's bloodstream where they import nutrients such as glucose across their body surface (the tegument). The parasite tegument is an unusual structure since it is enclosed not by the typical one but by two closely apposed lipid bilayers. Within the tegument two glucose importing proteins have been identified; these are schistosome glucose transporter (SGTP) 1 and 4. SGTP4 is present in the host interactive, apical tegumental membranes, while SGTP1 is found in the tegumental basal membrane (as well as in internal tissues). The SGTPs act by facilitated diffusion. To examine the importance of these proteins for the parasites, RNAi was employed to knock down expression of both SGTP genes in the schistosomula and adult worm life stages. Both qRT-PCR and western blotting analysis confirmed successful gene suppression. It was found that SGTP1 or SGTP4-suppressed parasites exhibit an impaired ability to import glucose compared to control worms. In addition, parasites with both SGTP1 and SGTP4 simultaneously suppressed showed a further reduction in capacity to import glucose compared to parasites with a single suppressed SGTP gene. Despite this debility, all suppressed parasites exhibited no phenotypic distinction compared to controls when cultured in rich medium. Following prolonged incubation in glucose-depleted medium however, significantly fewer SGTP-suppressed parasites survived. Finally, SGTP-suppressed parasites showed decreased viability in vivo following infection of experimental animals. These findings provide direct evidence for the importance of SGTP1 and SGTP4 for schistosomes in importing exogenous glucose and show that these proteins are important for normal parasite development in the mammalian host.
Validating an Instrument for Assessing Workforce Collaboration

The community college has always played an integral role in job training but never more so than following the 1998 Workforce Investment Act (WIA) that significantly increased the community colleges' opportunity to join with others in the provision of job training services. With this, however, came demand for high levels of collaboration between the state's community colleges and Workforce Investment Network (WIN) Job Centers, as WIA-mandated partnering agencies. In this study, an instrument developed by Mattessich and Monsey (1992) for measuring inter-agency collaboration was used in surveying community college personnel and WIN Job Center personnel. There were two major goals of this research effort, the first of which was the validation of the instrument, the Wilder Collaboration Factor Inventory. The second goal was to determine the level of collaboration between Mississippi's 15 community colleges and the Mississippi Department of Employment Security's 45 comprehensive WIN Job Centers. The results of a factor analysis support the constructs proposed in the Wilder instrument as being key elements of successful collaboration. Some areas of strength reported by the 572 participants were shared history, favorable climate and culture for collaboration, adaptability, as well as the organizations having a unique purpose. Areas reflecting concern include open and frequent communication, having multiple layers of participation, and the adequacy of resources. Additional data suggest other areas of strengths and areas of concern regarding the collaborative effort between the community college and WIN Job Center partners.
Calculation of terahertz antenna gratings generated by illumination of semiconductor

The development of UHF antenna devices for high data transmission rates is topical nowadays due to the overload of the explored radiofrequency range. In this paper, we describe the concept of optical antenna which can be used in terahertz frequency. It is based on diffraction grating theory and the ability of semiconductors to change their conductivity under light illumination.

A mobile robot system for automatic floor marking

This paper describes a patent awarded system for automatically marking the positions of stands for a trade fair or exhibition. The system has been in operation since August 2003 and has been used for every exhibition in the three main exhibition halls at the Stockholm International Fair since then. The system has speeded up the marking process significantly. What used to be a job for two men over 8 h now takes one robot monitored by one man 4 h to complete. The operators of the robot are from the same group of people that previously performed the marking task manually. Environmental features are much further away than in most other indoor applications and even many outdoor applications. Experiments show that many of the problems that are typically associated with the large beam width of ultrasonic sensors in normal indoor environments manifest themselves here for the laser because of the long range. Reaching the required level of accuracy was only possible by proper modeling of the laser scanner. The system has been evaluated by hand measuring 680 marked points. To make the integration of the robot system into the overall system as smooth as possible the robot uses information from the existing computer aided design (CAD) model of the environment in combination with a SICK LMS 291 laser scanner to localize the robot. This allows the robot to make use of the same information about changes in the environment as the people administrating the CAD system. © 2006 Wiley Periodicals, Inc.
