On Dynamical Behaviors and Chaos Control of the Fractional-Order Financial System

In this work, the authors investigate the stability conditions in a fractional-order financial system using the fractional Routh-Hurwitz criteria. According to the qualitative theory, the existence and uniqueness of solutions for a class of commensurate fractional-order financial systems are investigated. A necessary condition for this system to remain chaotic is obtained. It is found that chaos exists in this system with order less than three. Furthermore, the fractional Routh-Hurwitz conditions are used to control chaos in the proposed fractional-order system to its equilibria via linear feedback control method. Then, it is shown that the fractional-order financial system is controllable just in the fractional-order case when using a specific choice of linear controllers. Numerical simulations are used to verify the analytical results. DOI: 10.4018/978-1-4666-2509-9.ch002
The Net Repressor Is Regulated by Nuclear Export in Response to Anisomycin, UV, and Heat Shock

ABSTRACT The ternary complex factors (TCFs) are targets for Ras/mitogen-activated protein kinase signalling pathways. They integrate the transcriptional response at the level of serum response elements in early-response genes, such as the c-fosproto-oncogene. An important aim is to understand the individual roles played by the three TCFs, Net, Elk1, and Sap1a. Net, in contrast to Elk1 and Sap1a, is a strong repressor of transcription. We now show that Net is regulated by nuclear-cytoplasmic shuttling in response to specific signalling pathways. Net is mainly nuclear under both normal and basal serum conditions. Net contains two nuclear localization signals (NLSs); one is located in the Ets domain, and the other corresponds to the D box. Net also has a nuclear export signal (NES) in the conserved Ets DNA binding domain. Net is apparently unique among Ets proteins in that a particular leucine in helix 1, a structural element, generates a NES. Anisomycin, UV, and heat shock induce active nuclear exclusion of Net through a pathway that involves c-Jun N-terminal kinase kinase and is inhibited by leptomycin B. Nuclear exclusion relieves transcriptional repression by Net. The specific induction of nuclear exclusion of Net by particular signalling pathways shows that nuclear-cytoplasmic transport of transcription factors can add to the specificity of the response to signalling cascades.

Kinesin-1 mediates translocation of the meiotic spindle to the oocyte cortex through KCA-1, a novel cargo adapter

In animals, female meiotic spindles are attached to the egg cortex in a perpendicular orientation at anaphase to allow the selective disposal of three haploid chromosome sets into polar bodies. We have identified a complex of interacting Caenorhabditis elegans proteins that are involved in the earliest step in asymmetric positioning of anastral meiotic spindles, translocation to the cortex. This complex is composed of the kinesin-1 heavy chain orthologue, UNC-116, the kinesin light chain orthologues, KLC-1 and -2, and a novel cargo adaptor, KCA-1. Depletion of any of these subunits by RNA interference resulted in meiosis I metaphase spindles that remained stationary at a position several micrometers from the cell cortex during the time when wild-type spindles translocated to the cortex. After this prolonged stationary period, unc-116(RNAi) spindles moved to the cortex through a partially redundant mechanism that is dependent on the anaphase-promoting complex. This study thus reveals two sequential mechanisms for translocating anastral spindles to the oocyte cortex.
A new algorithm to threshold the courtesy amount of Brazilian bank checks

This paper describes a new algorithm for thresholding the courtesy amount of Brazilian bank checks. These images have complex backgrounds which is a problem for an automatic recognition system. The new approach is based on Tsallis entropy to find the best threshold value. Histogram specification is also used for preprocessing some images. The bi-level images are analyzed through several quantitative measures and it achieved the best results when compared with the images produced by other classical thresholding algorithms.
Macrophage Interaction with Paracoccidioides brasiliensis Yeast Cells Modulates Fungal Metabolism and Generates a Response to Oxidative Stress

Macrophages are key players during Paracoccidioides brasiliensis infection. However, the relative contribution of the fungal response to counteracting macrophage activity remains poorly understood. In this work, we evaluated the P. brasiliensis proteomic response to macrophage internalization. A total of 308 differentially expressed proteins were detected in P. brasiliensis during infection. The positively regulated proteins included those involved in alternative carbon metabolism, such as enzymes involved in gluconeogenesis, beta-oxidation of fatty acids and amino acids catabolism. The down-regulated proteins during P. brasiliensis internalization in macrophages included those related to glycolysis and protein synthesis. Proteins involved in the oxidative stress response in P. brasiliensis yeast cells were also up-regulated during macrophage infection, including superoxide dismutases (SOD), thioredoxins (THX) and cytochrome c peroxidase (CCP). Antisense knockdown mutants evaluated the importance of CCP during macrophage infection. The results suggested that CCP is involved in a complex system of protection against oxidative stress and that gene silencing of this component of the antioxidant system diminished the survival of P. brasiliensis in macrophages and in a murine model of infection.
Differential assessment of attention and impulsivity in children.

Abstract A sample of 72 unselected school children was administered the continuous performance test. Of the four types of commission errors that were identified, two occurred at significantly different reaction times than correct responses. One was characterized by fast reaction times and appears to reflect impulsive or rapid responding, while the other occurred at slow reaction times and appears to be caused by inattention. Correlations with teacher ratings of behavior further support the notion that different types of commission errors assess different underlying psychological functions.
A Proposed Framework for Development of a Visualizer Based on Memory Transfer Language (MTL)

Computer programming is among the fundamental aspects of computer science curriculum. Many students first introduced to introductory computer programming courses experience difficulties in learning and comprehending. Vast amount of researches have revealed that, generally programming courses are regarded as difficult and challenging and thus often have the highest dropout rates. Moreover, numerous researches have devoted in delivering new approaches and tools in enhancing the process of teaching and learning computer programming to novice programmers. One among the tools that have emerged to offer positive results is Program Visualization tool (Visualizer). Visualizers have shown remarkable contributions in facilitating novices to learn and comprehend computer programming. In addition to that, an approach to visualize codes execution, Memory Transfer Language (MTL), allows a novice to animate the code through paper and pencil mechanism without actively involving the machine. MTL depends on the concepts of RAM (Random Access Memory) to interpret the code line by line. Programming requires effort and special approach in the way it is learned and taught, thus this paper aimed at presenting a proposed framework for developing a visualizer that employs the use of MTL to enhance teaching and learning programming.
EXOTIC SUBFACTORS OF FINITE DEPTH WITH JONES INDICES (5 + 13)/2 AND (5 + 17)/2

We prove existence of subfactors of finite depth of the hyperfinite II1 factor with indices (5 + √ 13)/2 = 4.302 · · · and (5 + √ 17)/2 = 4.561 · · ·. The existence of the former was announced by the second named author in 1993 and that of the latter has been conjectured since then. These are the only known subfactors with finite depth which do not arise from classical groups, quantum groups or rational conformal field theory.
Model-Dependence of Shapiro Time Delay and the “ Speed of Gravity / Speed of Light ” Controversy

Fomalont and Kopeikin have recently succeeded in measuring the velocity-dependent component of the Shapiro time delay of light from a quasar passing behind Jupiter. While there is general agreement that this observation tests the gravitomagnetic properties of the gravitational field, a controversy has emerged over the question of whether the results depend on the speed of light, c, or the speed of gravity, c g. By analyzing the Shapiro time delay in a set of " preferred frame " models, I demonstrate that this question is ill-posed: the distinction can only be made in the context of a class of theories in which c = c g , and the answer then depends on the specific class of theories one chooses. It remains true, however, that for a large class of theories " close enough " to general relativity, the leading contribution to the time delay depends on c and not c g ; within this class, observations are thus not yet accurate enough to measure the speed of gravity.
The Influence of Area 5 on the Excitation of Primary Motor Cortex

Using functional magnetic resonance imaging in humans, Brodmann's area 5 (BA5) is observed to be activated during the suppression of motor output in the context of a NO-GO task. In monkeys, BA5 is associated with somatosensation and specifically linked with motor preparation. The goal of this thesis is to investigate BA5 influences on corticospinal excitability prior to the onset of movement, in the context of a GO/NO-GO paradigm. To achieve this goal, paired-pulse TMS is used to probe the functional connectivity between BA5 and ipsilateral primary motor cortex (M1) for a muscle specific to the hand. Three experiments are performed that investigate the differences in corticospinal output to the hand in a GO task versus a NO-GO task and the stimulation parameters that reveal such differences. Results indicate that BA5 is able to condition M1 prior to movement in a task-specific manner. Further, motor evoked potentials (MEPs) are suppressed in the context of a NO-GO task relative to a GO task, and task-specific differences rely on the intensity and direction of induced current in the cortex. In conclusion, data from this thesis contribute to our understanding of the role of BA5 in motor control.
D-PALD: A Dynamic Power-Aware Load Dispatcher with Response Time Percentile Guarantee in Heterogeneous Clusters

The power consumption of a server is not linear to its activeness, i.e., a server with 10% load may still draw as much as 60% of its peak power, therefore, a significant amount of energy has been used to keep servers active even under very light or idle loads. The resulting effect has been increased low power-effectiveness in data centers which elevate ownership costs and put more pressure on rack and enclosure densities. This motivates us to design a scheme to dynamically dispatch load to achieve energy efficiency while maintaining the quality of service (QoS) by exploiting a fundamental characteristic of data centers: heterogeneity. In this work, we propose D-PALD to guarantee response time percentile while dynamically dispatch the workload among the servers to maximize the power efficiency in heterogeneous data centers. We develop a power efficiency model to characterize properties of servers while providing the percentile guarantee and also design a power aware load dispatching algorithm. Our experiments demonstrate that DPALD can save a significant amount of power without sacrificing user performance compared to the baseline power management algorithms.
Outer membrane permeability barrier to azithromycin, clarithromycin, and roxithromycin in gram-negative enteric bacteria

Mutations which severely affect the function of the outer membrane of Escherichia coli and Salmonella typhimurium (lpxA and firA mutations of lipid A synthesis and rfaE mutation of the lipopolysaccharide inner-core synthesis) were found to decrease the MICs of erythromycin, roxithromycin, clarithromycin, and azithromycin by factors of 32 to 512, 32 to 1,024, 64 to 512, and 16 to 64, respectively. The sensitization factors for three other hydrophobic antibiotics (rifampin, fusidic acid, and mupirocin) ranged from 16 to 300. The outer membrane permeability-increasing agents polymyxin B nonapeptide (3 micrograms/ml) and deacylpolymyxin B (1 microgram/ml) sensitized wild-type E. coli to azithromycin by factors of 10 and 30, respectively. Quantitatively very similar sensitization to the other macrolides took place. Polymyxin-resistant pmrA mutants of S. typhimurium displayed no cross-resistance to azithromycin. Proteus mirabilis mutants which were sensitized to polymyxin by a factor of > or = 300 to > or = 1,000 had a maximal two- to fourfold increase in sensitivity to azithromycin. These results indicate that azithromycin and the other new macrolides use the hydrophobic pathway across the outer membrane and that the intact outer membrane is an effective barrier against them. Furthermore, the results indicate that azithromycin, in contrast to polymyxin, does not effectively diffuse through the outer membrane by interacting electrostatically with the lipopolysaccharide.
Filtering for Discrete-Time Networked Nonlinear Systems With Mixed Random Delays and Packet Dropouts

In this technical note, a new class of discrete-time networked nonlinear systems with mixed random delays and packet dropouts is introduced, and the H∞ filtering problem for such systems is investigated. The mixed stochasitc time-delays consist of both discrete and infinite distributed delays and the packet dropout phenomenon occurs in a random way. Furthermore, new techniques are presented to deal with the infinite distributed delay in the discrete-time domain. Sufficient conditions for the existence of an admissible filter are established, which ensure the asymptotical stability as well as a prescribed H∞ performance. Finally, examples are given to demonstrate the effectiveness of the proposed filter design scheme in this technical note.
1 Summary — What is Private Information Retrieval ?

In this set of lecture notes we begin a brief discussion of Private Information Retrieval (PIR). We begin by defining what PIR is about. We then present two PIR protocols, and give simple proofs that these two protocols are indeed correct. Finally, we discuss some generalizations of these basic schemes. Let us begin by introducing the problem. Suppose we have a database DB = (x1, . . . , xn), viewed as an n-bit string (i.e., the database has n entries, with each entry being a single bit). Suppose further that a user wants to learn the i bit of the database without leaking to the database administrator any information about i (in an information-theoretic sense). Informally, this is known as the PIR problem. Note that there does exist a solution: simply send to the user the contents of the entire database. The user can discard all the entries other than the one it is interested in, and the database clearly learns no information about which entry this is. The communication complexity of this solution, however, is O(n). The PIR problem asks: can we do better? It is actually not too difficult to show that it is impossible to do better in the above scenario if we require information-theoretic privacy for the user (i.e., even an all-powerful database learns nothing about the bit i the user is interested in) [1]. Thus, we must relax the scenario a bit to allow for more efficient solutions. One possibility that we explore here is to assume that there are multiple (identical) copies of the database, and the administrators of these databases cannot communicate with each other. We see that this allows for much more efficient solutions (in terms of their communication complexity).
To What Extent Do the PANSS and CGI-S Overlap?

Background: The Positive and Negative Symptom Scale (PANSS) and Clinical Global Impression (CGI-S) item for severity are used together to measure severity of psychotic illness. PANSS is the "gold standard" measure of efficacy, but it is not always feasible to use, yet the CGI-S requires validation. Objectives: To examine the overlap between PANSS and CGI-S. Methods: The overlap of the PANSS and CGI-S were examined using data from 7 large antipsychotic clinical trials (n = 4287). Results: Regression analysis identified 21% to 60% overlap of the measures depending on the trial and measurement point. The pooled study mean PANSS value corresponding with a CGI-S of 2, 3, and 4 were 67.1 (n = 799), 79.6 (n = 1645), and 92.4 (n = 1056), respectively. A decrease of 1 on the CGI-S corresponded to a 20% decline on the PANSS. Of the 37 planned comparisons in these studies, there was an agreement between the PANSS and CGI-S on change from baseline to end point on 32 comparisons and on dichotomized change variables (PANSS ≥−20% and CGI-S ≥−1 point) on 31 comparisons. The differences in the remaining comparisons would not have changed the conclusions of the studies. The positive and disorganized PANSS scales were the most closely related to the CGI-S, followed by hostility and negative scale with almost no association with anxiety/depression. Conclusions: The CGI-S and PANSS are correlated but are not synonymous. Both measures, however, show substantial agreement in detecting change, and the CGI-S shows overlap with the core symptoms of schizophrenia.
Sucrose for Procedural Pain Management in Infants

The use of oral sucrose has been the most extensively studied pain intervention in newborn care to date. More than 150 published studies relating to sweet-taste-induced calming and analgesia in human infants have been identified, of which 100 (65%) include sucrose. With only a few exceptions, sucrose, glucose, or other sweet solutions reduced pain responses during commonly performed painful procedures in diverse populations of infants up to 12 months of age. Sucrose has been widely recommended for routine use during painful procedures in newborn and young infants, yet these recommendations have not been translated into consistent use in clinical practice. One reason may be related to important knowledge and research gaps concerning analgesic effects of sucrose. Notably, the mechanism of sweet-taste-induced analgesia is still not precisely understood, which has implications for using research evidence in practice. The aim of this article is to review what is known about the mechanisms of sucrose-induced analgesia; highlight existing evidence, knowledge gaps, and current controversies; and provide directions for future research and practice.
Low Power Low Voltage OTA using Adaptive Bias

The very fast growing market of portable equipment is increasing interest in low power integrates circuit. So, designing low power integrated circuits requires reduction of supply voltages and interconnection parasitic to minimum but reduction in supply voltage implies series of problems in circuit design. To overcome these issues, an Ultra low power low voltage two stage class AB CMOS fully differential operational amplifier Op-Amp) operating at 0.4 V supply design in low cost 90nm CMOS technology is proposed.
Gnaq and Gna11 in the Endothelin Signaling Pathway and Melanoma

In this article, we first briefly outline the function of G protein coupled receptors in cancer, and then specifically examine the roles of the seven transmembrane G protein coupled Endothelin B receptor (Ednrb) and the G proteins, GNAQ and GNA11, in both melanocyte development and melanoma. Ednrb plays an essential role in melanocyte development. GNAQ and GNA11 are oncogenes when mutated in certain types of melanocytic lesions, being extremely frequent in uveal melanoma, which forms from melanocytes located in the eye. Previously, we reported that in mice, Schwann cell precursor derived melanocytes colonize the dermis and hair follicles, while the inter-follicular epidermis is populated by other melanocytes. A pattern has emerged whereby melanocytes whose activities are affected by gain-of-function mutations of the Endothelin 3 ligand and Gαq/11 are the same subset that arise from Schwann cell precursors. Furthermore, the forced expression of the constitutively active human GNAQQ209L oncogene in mouse melanocytes only causes hyper-proliferation in the subset that arise from Schwann cell precursors. This has led us to hypothesize that in Schwann cell precursor derived melanocytes, Ednrb signals through Gαq/11. Ednrb is promiscuous and may signal through other G protein alpha subunits in melanomas located in the inter-follicular epidermis.
A PROPOSED RDIT ALGORITHM FOR ANALYSIS OF FACE VERIFICATION IN VIDEOS IN IMAGE DATABASE FOR CRIME INVESTIGATION

In the face recognition most researches has considered about face detection and identification or a face detection and tracking, but best of our knowledge very few researches has focused on the face detection, identification and tracking. The combination of these three mechanism are been used in many real time applications . Here we consider one of the application as theft detection in real time which proposes a new mechanism named as FACE RDIT (Face Rectangular Detection, Identification and tracking) algorithms. Also here we include some preprocessing algorithms like gray scale conversion and histogram equalization for image enhancement process. Apart from this we also derive a new algorithm which is based on rectangular features of the face and multi linear training. Also the proposed technique has four main steps like training, detection, identification and tracking by using this proposed method we train the unauthorized users photo and then make the detection of the faces in the group of frames and then identify the particular personality from the group of images. Finally it tracks the identified thief in next following video frames by our proposed algorithm. Thus the effectiveness of the proposed methods is well supported by both detailed analysis and extensive experimentation on a face verification problem.
