O C ] 2 7 D ec 2 00 6 Parameter-Dependent S-Procedure And Yakubovich Lemma

The paper considers a linear matrix inequality (LMI) that depends on a parameter varying in a compact topological space. It turns out that if a strict LMI continuously depends on a parameter and is feasible for any value of that parameter, then it has a solution which continuously depends on the parameter. The result holds true for LMIs that arise in S-procedure and Yakubovich lemma. It is shown that the LMI which is polynomially dependent on a vector of parameters can be reduced to a parameter-independent LMI of a higher dimension. The result is based on the recent generalization of Yakubovich lemma proposed by Iwasaki and Hara and another generalization formulated in this paper. The problem of positivity verification for a non-SOS polynomial of two variables is considered as an example. To illustrate control applications, a method of parameter-dependent Lyapunov function construction is proposed for nonlinear systems with parametric uncertainty. Comment: The paper was presented at the 5th Russian-Swedish Control Conference, Lund, Sweden, 29–30 August 2006.
Introduction: Origins of the Concept

Reviews the theoretical and empirical study of the regional innovation system (RIS), serving as an introduction to a collection of essays on the notion. Though there has been an upsurge surrounding the study of national systems of innovation since the 1980s, it was not until 1992 that the term 'regional innovation system' came into use. The RIS is characterized by economic coordination emphasizing the importance of cultural factors, including trust, cooperation, and social network relationships. A typology of regional innovation systems is formulated, drawing on regional science and innovation studies, and rejecting the neoclassical explanation in favor of an evolutionary theory of economics. This formulation includes analysis of grassworks, network, dirigiste, localist, interactive, and globalized RIS, as well as the key roles of governance and business innovation. In contrast to neoclassical theory, which posits the firm as a homogenous, atomistic unit of rational utility maximization, in evolutionary economics the firm is differentiated, making use of heterogeneous inputs, and learns through the double feedback loop of assessing its own experience and the experience of peers. The process of innovation becomes systematic as it develops within clusters of inter-firm relationships. 'Learning by doing,' 'learning by using' and 'learning by interaction' are three complementary approaches to instilling a learning culture in industry -- that is, a culture characterized by institutional, cooperative learning that leads to innovative progress. Policy should serve as the infrastructure reinforcing this learning economy by supporting linkages between society and economy. Finally, to set up the question of the region's importance to economics in the age of globalization that will be explored in later essays in this book, the region is defined as a system of collective order maintained through trust and reliability, rather than, at it has traditionally been defined, an area characterized by economic specificity, administrative homogeneity, and shared culture. The other essays in this book are organized intto three categories: market-driven and informal coordination, network governance, and the impact of public policies. (CJC)
Electromagnetic fields act via activation of voltage-gated calcium channels to produce beneficial or adverse effects

The direct targets of extremely low and microwave frequency range electromagnetic fields (EMFs) in producing non‐thermal effects have not been clearly established. However, studies in the literature, reviewed here, provide substantial support for such direct targets. Twenty‐three studies have shown that voltage‐gated calcium channels (VGCCs) produce these and other EMF effects, such that the L‐type or other VGCC blockers block or greatly lower diverse EMF effects. Furthermore, the voltage‐gated properties of these channels may provide biophysically plausible mechanisms for EMF biological effects. Downstream responses of such EMF exposures may be mediated through Ca2+/calmodulin stimulation of nitric oxide synthesis. Potentially, physiological/therapeutic responses may be largely as a result of nitric oxide‐cGMP‐protein kinase G pathway stimulation. A well‐studied example of such an apparent therapeutic response, EMF stimulation of bone growth, appears to work along this pathway. However, pathophysiological responses to EMFs may be as a result of nitric oxide‐peroxynitrite‐oxidative stress pathway of action. A single such well‐documented example, EMF induction of DNA single‐strand breaks in cells, as measured by alkaline comet assays, is reviewed here. Such single‐strand breaks are known to be produced through the action of this pathway. Data on the mechanism of EMF induction of such breaks are limited; what data are available support this proposed mechanism. Other Ca2+‐mediated regulatory changes, independent of nitric oxide, may also have roles. This article reviews, then, a substantially supported set of targets, VGCCs, whose stimulation produces non‐thermal EMF responses by humans/higher animals with downstream effects involving Ca2+/calmodulin‐dependent nitric oxide increases, which may explain therapeutic and pathophysiological effects.
An efficient and privacy protection multi-server authentication scheme for low-cost RFID tags

Due to the wide use of the Internet and information technology, there are many attractive services provided in the network environment. Since the Internet is a public environment, a user must pass the authentication before using these services. Also, due to the reduced cost of the RFID tags, RFID technologies are widely used in various information applications. In this paper, we propose a mutual authentication RFID scheme for multiserver environment. Since in our proposed scheme, the tag only needs random number generation and one-way hash function operations, the computation cost for the tags is low. Our scheme does not need to store any verification table in the server and the registration center. Our proposed scheme can withstand all well-known security attacks, and can achieve anonymity for the tag.
Evaluation of Biochemical, Hematological and Parasitological Parameters of Protein-Deficient Hamsters Infected with Ancylostoma ceylanicum

Background Hookworms infect millions of people worldwide and can cause severe clinical symptoms in their hosts. Prospective cohort studies in Brazil show high rates of hookworm reinfection in malnourished children compared to well-nourished children, despite previous treatment. Additionally, soil-transmitted helminth (STH) infections can worsen the nutritional status of affected populations. Therefore, this study aims to clarify the effects of host malnutrition during Ancylostoma ceylanicum infection and how this infection affects host physiological parameters using a hamster model. Methodology/Principal Findings Hamsters were divided into four experimental groups: normal diet or low-protein diet (also referred to as “malnourished”) and A. ceylanicum infection or no infection. More severe pathogenesis was observed in the infected malnourished group, as demonstrated by significant decreases in the hemoglobin concentration, erythrocyte number and packed-cell volume compared to the non-infected malnourished group. Greater numbers of adult parasites and eggs were observed in the malnourished group compared to the control group; however, the oviposition rate was lower in the malnourished group. In general, greater values of total lipids were observed in malnourished animals compared to control animals, including lipids excreted in the stool. Conclusions In this work, we have demonstrated that animals fed an isocaloric low-protein diet presented more severe pathogenesis when infected with A. ceylanicum. The increased lipid concentration in the liver and blood is related to the conversion of the excess carbohydrate into fatty acids that increase the concentration of triglycerides in general. Triglycerides were excreted in the feces, indicating that infection associated with malnutrition caused a greater loss of these molecules for this group of animals and confirming the hypothesis that both nutrition and infection are responsible for the malabsorption syndrome. Taken together, the results found in this work confirm the hypothesis that the nutritional condition of the host greatly influences the course of the infection.
A remark on Bourgain's distributional inequality on the Fourier spectrum of Boolean functions

Bourgain’s theorem says that under certain conditions a function f : {0,1} n ! {0,1} can be approximated by a function g which depends only on a small number of variables. By following his proof we obtain a generalization for the case that there is a nonuniform product measure on the domain of f.
Divide and Conquer: Progress in the Molecular Stratification of Cancer

Cancer remains an outstanding cause of global morbidity and mortality, despite intensive research and unprecedented insights into the basic mechanisms of cancer development. A plethora of clinical and experimental evidence suggests that cancers from individual patients are likely to be molecularly heterogeneous in their use of distinct oncogenic pathways and biological programs. Efforts to significantly impact cancer patient outcomes will almost certainly require the development of robust strategies to subdivide such heterogeneous panels of cancers into biologically and clinically homogenous subgroups, for the purposes of personalizing treatment protocols and identifying optimal drug targets. In this review, I describe recent progress in the development of both targeted and genome-wide approaches for the molecular stratification of cancers, drawing examples from both the haematopoietic and solid tumor malignancies.
A Mobile App Offering Distractions and Tips to Cope With Cigarette Craving: A Qualitative Study

Background Despite considerable effort, most smokers relapse within a few months after quitting due to cigarette craving. The widespread adoption of mobile phones presents new opportunities to provide support during attempts to quit. Objective To design and pilot a mobile app "DistractMe" to enable quitters to access and share distractions and tips to cope with cigarette cravings. Methods A qualitative study with 14 smokers who used DistractMe on their mobiles during the first weeks of their quit attempt. Based on interviews, diaries, and log data, we examined how the app supported quitting strategies. Results Three distinct techniques of coping when using DistractMe were identified: diversion, avoidance, and displacement. We further identified three forms of engagement with tips for coping: preparation, fortification, and confrontation. Overall, strategies to prevent cravings and their effects (avoidance, displacement, preparation, and fortification) were more common than immediate coping strategies (diversion and confrontation). Tips for coping were more commonly used than distractions to cope with cravings, because they helped to fortify the quit attempt and provided opportunities to connect with other users of the application. However, distractions were important to attract new users and to facilitate content sharing. Conclusions Based on the qualitative results, we recommend that mobile phone-based interventions focus on tips shared by peers and frequent content updates. Apps also require testing with larger groups of users to assess whether they can be self-sustaining.
An accelerated fully homomorphic encryption scheme over the integers

Based on the public key compressing technique and the Chinese Remainder Theorem, an efficient somewhat homomorphic encryption (SWHE) scheme is proposed, whose security can be reduced to the approximate greatest common divisor problem. Then the fully homomorphic encryption scheme is obtained by using Gentry's squashing decryption circuit technique, which could resist chosen plaintext attacks. The efficiency analysis shows that our SWHE scheme's public key size and ciphertext size are reduced compared to DGHV scheme. And the simulation results show that the multiplication of the proposed SWHE scheme is much more efficient than that of DGHV scheme.
Point-to-line metric based Iterative Closest Point with bounded scale

This paper introduces a novel approach named the point-to-line metric based Iterative Closest Point (ICP) with bounded scale algorithm, which integrates a scale with boundaries into the traditional point-to-line metric-based ICP algorithm. It converges quadratically, requires few number of iterations and is not sensitive to large initial displacement errors. Based on the analysis of the error function being minimized, a efficient solution is proposed to reduce the computational cost. The proposed technique is fit for both laser scan data sets and other 2D m-D point sets, and yields more satisfying robust results than the traditional point-to-line ICP method. Further more, it provides a method to calculate the covariance of registration results. Experimental results illustrate the feasibility of the proposed theory and algorithms.
An improved technique for reducing false alarms due to soft errors

A significant fraction of soft errors in modern microprocessors has been reported to never lead to a system failure. Any concurrent error detection scheme that raises alarm every time a soft error is detected is not well heeded because most of these alarms are false and responding to them will affect system performance negatively. This paper improves state of the art in detecting and preventing false alarms. Existing techniques are enhanced by a methodology to handle soft errors on address bits. Furthermore, we demonstrate benefit of false alarm identification in implementing a roll-back recovery system by first calculating the optimum check pointing interval for a roll-back recovery system and then showing that the optimal number of check-points decreases by orders of magnitude when exclusion techniques are used even if the implementation of exclusion technique is not perfect
Oncotargets and Therapy Dovepress Dovepress Obstructive Jaundice Caused by Intraductal Metastasis of Lung Adenocarcinoma

Obstructive jaundice caused by metastases to the porta hepatis is often observed in patients with various advanced cancers; however, metastasis of lung cancer to the common bile duct with subsequent development of jaundice is rare. A 75-year-old female with lung adenocarcinoma harboring epidermal growth factor receptor (EGFR) mutation (15-bp in-frame deletion in exon 19 and T790M in exon 20) developed obstructive jaundice during therapy. Obstruction of the common bile duct caused by an intraductal tumor was identified by computed tomography, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasonography. Although primary cholangiocarcinoma was highly suspected according to the imaging findings, immunohistochemical evaluation of the intraductal tumor demonstrated thyroid transcription factor-1 positive adenocarcinoma. Furthermore, peptide nucleic acid-locked nucleic acid poly-merase chain reaction clamp analysis showed that the tumor contained the same EGFR mutation as that in the primary lung cancer. Thus, we confirmed intraductal metastasis from a lung adenocarcinoma. To our knowledge, this is the second report of obstructive jaundice caused by intraductal metastasis of lung cancer.
A Novel Nine Level Grid-Connected Inverter for Photovoltaic System

This paper proposes a single-phase sevenlevel inverter for grid-connected photovoltaic systems, with a novel pulse width-modulated (PWM) control scheme. Three reference signals that are identical to each other with an offset that is equivalent to the amplitude of the triangular carrier signal were used to generate the PWM signals. The inverter is capable of producing seven levels of output-voltage levels (Vdc, 2Vdc/3, Vdc/3, 0,−Vdc,−2Vdc/3,−Vdc/3) from the dc supply voltage. In this paper a new nine level inverter with reduced number of switches is proposed and Matlab/Simulink results are presented.
The research of the switching INS's working state based on the underwater vehicle space motion

Dynamic error of Platform inertial navigation system? INS? can be caused by vehicle movement, then the model of underwater vehicle will be built. The INS's working state can be decided by the controlling information of the underwater vehicle. This paper also gives the time when the submersible changes its motion state exactly. The INS's working state is switched at this time. This method can instead of the conventional way switching the INS's working state by accelerate meter or course changing. It will reduce the dynamic error caused by submersible motion.
An Economic Analysis of the Nashville Living Wage Proposals

Robert Pollin and Jeannette Wicks-Lim consider the economic impact of two living wage proposals for Nashville-Davidson County, Tennessee. Pollin and Wicks-Lim look at the overall costs of each proposal, which offer a wage of $10.80 per hour and health insurance benefits to two alternative pools of workers, and break those costs into direct wage costs, health insurance costs, and ripple-effect costs. They place these expenses in context as a share of the local government budget, and consider a range of potential revenue sources to cover them. The authors then discuss the benefits that the living wage proposals would bring, not only to the workers, but to state and local governments, businesses, and low-income communities in general.
A new algebraic method for robot motion planning and real geometry

We present an algorithm which solves the findpath or generalized movers' problem in single exponential sequential time. This is the first algorithm for the problem whose sequential time bound is less than double exponential. In fact, the combinatorial exponent of the algorithm is equal to the number of degrees of freedom, making it worst-case optimal, and equaling or improving the time bounds of many special purpose algorithms. The algorithm accepts a formula for a semi-algebraic set S describing the set of free configurations and produces a one-dimensional skeleton or "roadmap" of the set, which is connected within each connected component of S. Additional points may be linked to the roadmap in linear time. Our method draws from results of singularity theory, and in particular makes use of the notion of stratified sets as an efficient alternative to cell decomposition. We introduce an algebraic tool called the multivariate resultant which gives a necessary and sufficient condition for a system of homogeneous polynomials to have a solution, and show that it can be computed in polynomial parallel time. Among the consequences of this result are new methods for quantifier elimination and an improved gap theorem for the absolute value of roots of a system of polynomials.
Acquisition of sEMG Signals During Human Ankle Movement

This paper is concerned with studying human ankle movement based on surface electromyographic(sEMG) signals. The sEMG signals were collected from muscles of normal subjects when they moved their ankle flexion-extension. Two types of movement were designed including bending and extending. Analysis of sEMG(surface electromyogram) centered on two features; magnitude of activation & the degree of similarity of the sEMG distribution. sEMG is the technique for measuring levels of muscle activity. When a muscle contracts, electrical activity generated as action potentials propagate along the muscle fibers. There are two types of Surface EMG (SEMG)-Static scanning SEMG and Dynamic SEMG. In Dynamic SEMG, electrodes are attached to the skin and muscle activity is measured and graphed as the patient moves through various ranges of motion. The sEMG signals picked up during the muscle activity are interfaced with a PC system via cRIO for EMG acquisition. The acquired signals were processed and analyzed using filtering techniques. The results showed a marked variation in the amplitude level of EMG as the subject's ankle pace changed.
A vision-based technique for objective assessment of burn scars

In this paper a method for the objective assessment of burn scars is proposed. The quantitative measures developed in this research provide an objective way to calculate elastic properties of burn scars relative to the surrounding areas. The approach combines range data and the mechanics and motion dynamics of human tissues. Active contours are employed to locate regions of interest and to find displacements of feature points using automatically established correspondences. Changes in strain distribution over time are evaluated. Given images at two time instances and their corresponding features, the finite element method is used to synthesize strain distributions of the underlying tissues. This results in a physically based framework for motion and strain analysis. Relative elasticity of the burn scar is then recovered using iterative descent search for the best nonlinear finite element model that approximates stretching behavior of the region containing the burn scar. The results from the skin elasticity experiments illustrate the ability to objectively detect differences in elasticity between normal and abnormal tissue. These estimated differences in elasticity are correlated against the subjective judgments of physicians that are presently the practice.
Designing Schools To Enhance the Academic and Social Outcomes of All Students.

When students increasingly exhibited disruptive behavior at a particular school, a comprehensive multilevel discipline program was developed to respond to the students' behavior. The conceptual model and key intervention approaches used in this multilevel discipline program are described in this paper. Previous experience convinced school personnel that the school-wide discipline program must be based on the view that disruptive behavior is primarily a socialization problem rather than a sickness. Therefore, the discipline program emphasized direct intervention approaches within and across all school settings and it relied on teaching students acceptable social norms. The interventions are universal because all students are exposed in the same way at the same level. Outlined here are the school-wide discipline plan, ecological arrangements, behavioral guidelines, supervision, and classroom management strategy, also called think time. The latter emphasizes catching disruptive behavior early, designating a specific classroom for think time, monitoring students moving to and entering a designated think-time classroom, performing a think-time debriefing process, checking students' debriefing responses, watching students rejoin the class, employing the use of other consequences, and instituting guidelines governing the use of the think-time strategy. Also discussed are targeted interventions and some intensive comprehensive interventions. The program not only effectively reduced the level of disruptive behavior, but also enhanced the academic performance and school survival skills of at-risk and target students. Additionally, the program enabled teachers to shift their focus from discipline problems toward instructional matters.
