An observer based approach for multi-scroll chaotic system synchronization and secure communication with multi-shift ciphering

In this paper, a nonlinear observer based approach for multi-scroll chaotic system synchronization and information recovery with multi-shift ciphering is presented. The approach is based on using differential mean value theorem based observer design technique for chaotic system synchronization purpose. Here, by using a differential mean value theorem, nonlinear observer estimation error dynamics is transformed into a linear parameter varying system and sufficient condition for error convergence is derived using a quadratic Lyapunov function which is nonlinear matrix inequality with time varying parameters. The derived sufficient condition is then reformulated as a set of linear matrix inequalities using convexity principle and solved with MATLAB LMI toolbox. In the proposed scheme, security is enhanced by using multi-shift ciphering for information encryption and the key used for ciphering is one of the states of a chaotic system. The estimate of key is obtained by using differential mean value theorem based observer and used to recover encrypted data at the receiver side. An example of multi-scroll Chen system synchronization along with information encryption and decryption with simulation results is given to show the efficacy of the proposed approach.
Evaluation of Emerging Energy-Efficient Heterogeneous Computing Platforms for Biomolecular and Cellular Simulation Workloads

Many of the continuing scientific advances achieved through computational biology are predicated on the availability of ongoing increases in computational power required for detailed simulation and analysis of cellular processes on biologically-relevant timescales. A critical challenge facing the development of future exascale supercomputer systems is the development of new computing hardware and associated scientific applications that dramatically improve upon the energy efficiency of existing solutions, while providing increased simulation, analysis, and visualization performance. Mobile computing platforms have recently become powerful enough to support interactive molecular visualization tasks that were previously only possible on laptops and workstations, creating future opportunities for their convenient use for meetings, remote collaboration, and as head mounted displays for immersive stereoscopic viewing. We describe early experiences adapting several biomolecular simulation and analysis applications for emerging heterogeneous computing platforms that combine power-efficient system-on-chip multi-core CPUs with high-performance massively parallel GPUs. We present low-cost power monitoring instrumentation that provides sufficient temporal resolution to evaluate the power consumption of individual CPU algorithms and GPU kernels. We compare the performance and energy efficiency of scientific applications running on emerging platforms with results obtained on traditional platforms, identify hardware and algorithmic performance bottlenecks that affect the usability of these platforms, and describe avenues for improving both the hardware and applications in pursuit of the needs of molecular modeling tasks on mobile devices and future exascale computers.
Measles virus P gene codes for two proteins

The entirety of the phosphoprotein gene of measles virus has been sequenced. The gene is composed of 1,657 nucleotides and specifies a 507-amino-acid protein (P). A second overlapping reading frame was predicted from the sequence and specifies a 186-amino-acid protein (C). Through the use of antisynthetic peptide antibodies, we show that both proteins are expressed in virally infected cells. Both proteins are expressed from a functionally bicistronic mRNA through independent initiation of ribosomes at the respective AUG codons. Using immunofluorescent microscopy, we localized the C protein in the nucleus and in cytoplasmic inclusions within the infected cells.
Apraxia of Speech: An overview

Apraxia of speech (AOS) is a motor speech disorder that can occur in the absence of aphasia or dysarthria. AOS has been the subject of some controversy since the disorder was first named and described by Darley and his Mayo Clinic colleagues in the 1960s. A recent revival of interest in AOS is due in part to the fact that it is often the first symptom of neurodegenerative diseases, such as primary progressive aphasia and corticobasal degeneration. This article will provide a brief review of terminology associated with AOS, its clinical hallmarks and neuroanatomical correlates. Current models of motor programming will also be addressed as they relate to AOS and finally, typical treatment strategies used in rehabilitating the articulation and prosody deficits associated with AOS will be summarized.
A 280 mV-to-1.1 V 256b Reconfigurable SIMD Vector Permutation Engine With 2-Dimensional Shuffle

An ultra-low voltage reconfigurable 4-way to 32-way SIMD vector permutation engine is fabricated in 22 nm tri-gate bulk CMOS, consisting of a 32-entry 256b 3-read/1-write ported register file with a 256b byte-wise any-to-any permute crossbar for 2-dimensional shuffle. The register file integrates a vertical shuffle across multiple entries into read/write operations, and includes clock-less static reads with shared P/N dual-ended transmission gate (DETG) writes, improving register file by 250 mV across PVT variations with a wide dynamic operating range of 280 mV-1.1 V. The permute crossbar implements an interleaved folded byte-wise multiplexer layout forming an any-to-any fully connected tree to perform a horizontal shuffle with permute accumulate circuits, and includes vector flip-flops, stacked min-delay buffers, shared gates, and ultra-low voltage split-output (ULVS) level shifters improving logic by 150 mV, while enabling peak energy efficiency of 585 GOPS/W measured at 260 mV, 50 C. The permutation engine achieves: (i) nominal register file performance of 1.8 GHz, 106 mW measured at 0.9 V, 50 C, (ii) robust register file functionality measured down to 280 mV with peak energy efficiency of 154 GOPS/W, (iii) scalable permute crossbar performance of 2.9 GHz, 69 mW measured at 1.1 V, 50 C with sub-threshold operation at 240 mV, 10 MHz consuming 19 W, and (iv) a 64b 4 4 matrix transpose algorithm and AoS to SoA conversion with 40%–53% energy savings and 25%–42% improved peak throughput measured at 1.8 GHz, 0.9 V.

A Strongly Minimal Axiomatisation of Multivalued Dependencies in Incomplete Database Relations

We study inference rules for multivalued dependencies in relational databases with null values (NMVDs). The definition of NMVDs is dependent on the underlying relation schema R and this is reflected syntactically by the R-complementation rule which is present in all previous axiomatisation of NMVDs. The main result is a sound and complete set Lfr of inference rules in which the R-axiom is the only inference rule dependent on R. This result extends work of Biskup who has provided such an axiomatisation in the absence of null values. It is proven that the set Lfr is minimal in a very strong sense. In fact, none of its rules can be omitted without losing the ability to infer all trivial NMVDs
Respiratory synctial virus infection in BALB/c mice previously immunized with formalin-inactivated virus induces enhanced pulmonary inflammatory response with a predominant Th2-like cytokine pattern

Vaccination with formalin-inactivated respiratory syncytial virus (FI-RSV) caused excessive disease in infants upon subsequent natural infection with RSV. Recent studies with BALB/c mice have suggested that T cells are important contributors to lung immunopathology during RSV infection. In this study, we investigated vaccine-induced enhanced disease by immunizing BALB/c mice with live RSV intranasally or with FI-RSV intramuscularly. The mice were challenged with RSV 6 weeks later, and the pulmonary inflammatory response was studied by analyzing cells obtained by bronchoalveolar lavage 4 and 8 days after challenge. FI-RSV-immunized mice had an increased number of total cells, granulocytes, eosinophils, and CD4+ cells but a decreased number of CD8+ cells. The immunized mice also had a marked increase in the expression of mRNA for the Th2-type cytokines interleukin-5 (IL-5) and IL-13 as well as some increase in the expression of IL-10 (a Th2-type cytokine) mRNA and some decrease in the expression of IL-12 (a Th1-type cytokine) mRNA. The clear difference in the pulmonary inflammatory response to RSV between FI-RSV- and live-RSV-immunized mice suggests that this model can be used to evaluate the disease-enhancing potential of candidate RSV vaccines and better understand enhanced disease.
Automatic multi-image photo texturing of complex 3D scenes

The paper presents an approach for projective texture mapping from photographs onto triangulated surfaces from 3D laser scanning. By these means, the effort to generate photo-realistic models of complex shaped objects can be reduced considerably. The images are collected from multiple viewpoints, which do not necessarily correspond to the viewpoints of LIDAR data collection. In order to handle the resulting problem of occlusions, the visibility of the model areas in the respective images has to be established. For this purpose, the algorithm works in both image and object space and efficiently detects ambient, back-face and view frustum occlusions. Occluding polygons are labelled and separated with their connectivity to texture them recursively using the optimal of the available images until the final textured model is produced. After this visibility processing, colour values will be correctly assigned from the photograph to the visible polygons. In order to gain a high quality texture, lens distortion and colour corrections are applied during processing. The approach is demonstrated by generating high realistic 3D textured models for the Alkasneh monument in Petra city and a Romanian Theatre in the ancient city of Jerash.
Recognition of fasting or overall hyperglycaemia when starting insulin treatment in patients with type 2 diabetes in general practice

Objective. The efficacy of various regimens of initial insulin treatment in poorly controlled type 2 diabetes was compared with regard to diurnal glucose variation. Design. Randomized controlled trial. Setting. Insulin therapy initiated on hospital wards, follow-up as outpatients for 12 months. Subjects. Fifty-two type 2 diabetic patients (HbA1c >7.5%, mean 9.8%) on maximal oral therapy. Interventions. Insulin only (IO), bedtime insulin with sulphonylurea (glipizide) (IS), or bedtime insulin with metformin (IM). Main outcome measures. HbA1c and body weight. Results. HbA1c decreased on average by 1.8, 1.0 and 1.5 percentage points in the IO, IS, and IM groups, respectively (p always <0.025). Body weight increased, most in the IO patients (+6.2 kg), least in the IM patients (+3.4 kg). Analysing all treatment groups combined, a similar HbA1c reduction was observed in patients with overall hyperglycaemia (low fasting plasma glucose/HbA1c ratio) and in patients with fasting hyperglycaemia (high fasting plasma glucose/HbA1c ratio). Within the overall hyperglycaemia group, the IS and IM patients had smaller decreases in HbA1c (−1.5 and −1.3 percentage points, respectively) than the IO patients (−2.7 percentage points). On the other hand, within the fasting hyperglycaemia group HbA1c reductions were −1.2, −0.8 and −1.5 percentage points, in the IO, IS, and IM groups, respectively. Conclusion. Not all poorly controlled type 2 diabetic patients should automatically be treated with an oral agent and bedtime insulin. Two daily insulin injections is a valid choice, particularly if the patient has overall hyperglycaemia.
A novel generic architecture for the implementation of demand response programs in a smart grid

Nowadays, smart grid for electrical power distribution is considered as one of the most important infrastructures enabling the consumer to interact with other stakeholders to reach technical and economic objectives. This interactivity is performed through the concept of agreements that are signed between different involved actors (utility operators, electrical energy producers, consumers, electrical energy market traders, brokers…). These agreements are of the form of what is called Demand Response Programs (DRPs) which are already greatly diversified. In case of different DRPs implemented over the same network without any coordination, the network stability may get degraded rather than improved. Therefore, in order to make coordination easy to be realized, DRPs implementations based on a generic architecture become a must. In this paper, a novel generic architecture is presented. It is validated first by means of matching existing architectures with the suggested one and second by identifying some of the architecture components while implementing a DRP based on a real case study.
Use of serial ultrasound to identify periods of fetal growth restriction in relation to neonatal anthropometry

The developmental origins of the health and disease hypothesis suggests that fetal growth restriction (FGR) is a risk factor for several chronic diseases of adulthood. However, most supporting studies use birth weight as a proxy measure of FGR. To examine the relationship between birth weight and FGR, the present study used serial prenatal ultrasound to identify periods of FGR during gestation, and related these periods to birth size and shape. The data in this study included serial prenatal ultrasounds performed on 1,349 high‐risk Scandinavian women enrolled in the National Institute of Child Health and Human Development Study of Successive Small for Gestational Age Births. Fetal growth velocity between ultrasounds was used to identify periods of isolated FGR, and these were studied in relation to anthropometry at birth. FGR was identified in 184 subjects. A control group of 384 subjects without FGR was also identified. Infants with first‐trimester FGR (n = 20) had the highest birth weight, ponderal index, and subscapular skinfold thickness. Infants with second‐trimester FGR (n = 37) had the highest arm fat percentage. Infants with early third‐trimester FGR (n = 55) had the lowest mean birth weight and ponderal index. When infant gender, gestational age, maternal body mass index, and smoking were controlled, birth weight was predicted only by third‐trimester FGR (not first‐ or second‐trimester FGR), and arm fat percent was predicted only by second‐trimester FGR. These results suggest that birth weight is not a valid indicator of FGR occurring before the third trimester. Body composition may be a more sensitive marker of early FGR. Am. J. Hum.

Biodiversity in the Phanerozoic: a reinterpretation

Abstract Many features of global diversity compilations have proven robust to continued sampling and taxonomic revision. Inherent biases in the stratigraphic record may nevertheless substantially affect estimates of global taxonomic diversity. Here we focus on short-term (epoch-level) changes in apparent diversity. We use a simple estimate of the amount of marine sedimentary rock available for sampling: the number of formations in the stratigraphic Lexicon of the United States Geological Survey. We find this to be positively correlated with two independent estimates of rock availability: global outcrop area derived from the Paleogeographic Atlas Project (University of Chicago) database, and percent continental flooding. Epoch-to-epoch changes in the number of formations are positively correlated with changes in sampled Phanerozoic marine diversity at the genus level. We agree with previous workers in finding evidence of a diversity-area effect that is substantially weaker than the effect of the amount of preserved sedimentary rock. Once the mutual correlation among change in formation numbers, in diversity, and in area flooded is taken into consideration, there is relatively little residual correlation between change in diversity and in the extent of continental flooding. These results suggest that much of the observed short-term variation in marine diversity may be an artifact of variation in the amount of rock available for study. Preliminary results suggest the same possibility for terrestrial data. Like the comparison between change in number of formations and change in sampled diversity, which addresses short-term variation in apparent diversity, the comparison between absolute values of these quantities, which relates to longer-term patterns, also shows a positive correlation. Moreover, there is no clear temporal trend in the residuals of the regression of sampled diversity on number of formations. This raises the possibility that taxonomic diversity may not have increased substantially since the early Paleozoic. Because of limitations in our data, however, this question must remain open.
Targeted delivery of short-chain fatty acids to the human large bowel.

The cecum and colon are an integral, but somewhat neglected, part of the human digestive system. This digestion is affected not by human enzymes but by the microbiota that degrade undigested dietary components and body secretions that pass through the ileocecal valve. The main fermentative substrates are the indi-gestible polysaccharides that constitute the greater part of total dietary ﬁber, whereas the short-chain fatty acids (SCFAs) 2 acetate, propionate, and butyrate are important end products (1). Generally, SCFAs are formed in the order of acetate . propionate $ butyrate, the same as they are in ruminant and nonrumi-nant obligate herbivores. The 2 SCFAs of greatest potential interest for their physiologic effects (propionate and butyrate) are formed in the lowest amounts, which is clearly important for health outcomes. The similarity of the fermentation and its products between (omnivorous) humans and herbivores is striking. In fact, the ﬁrst comparison of SCFAs between species showed concentrations in the hind gut of the pig to be similar to those in the digestive ﬂuid of herbivores. The pig is an omnivore, like humans, and a study in stoma patients conﬁrmed high SCFA concentrations in efﬂuent from those with sigmoid colostomy and lower in those with distal colostomy and in feces (2). This is consistent with SCFA uptake by the host and, by extension, his or her metabolism. A recent study in surgical patients showed this to be true when concentrations in the major blood vessels were measured, including the hepatic portal vein (3). Rectal infusion of butyrate failed to increase peripheral blood concentrations, consistent with metabolism by the viscera. This means that mixed venous SCFAs are not necessarily a precise measure
Ensino Superior a Distância e Trabalho Docente: Recentes Configurações no Âmbito do Público e Privado / Higher Distance Education and Teacher's Work: Recent Settings Under the Public and Private

Neste trabalho apresentamos a materialidade da política educacional para o ensino superior na modalidade à distância, por meio da oferta de matrículas dos setores público e privado. Trabalhamos com as Sinopses da Educação Superior de 2000 a 2009, do Instituto Nacional de Estudos e Pesquisas Educacionais "Anísio Teixeira" (INEP), e também utilizamos como técnica de coleta de dados, entrevistas e questionários com professores e tutores de instituições públicas e privadas. Constatamos que existe uma tendência de crescimento do número das matrículas em cursos a distância em detrimento do crescimento das matrículas na modalidade presencial e, como consequência, uma mudança qualitativa do processo de trabalho docente, este centrado em uma divisão peculiar e em novas formas contratuais estabelecidas que apontam para a sua intensificação e precarização. ABSTRACT: This work presents the materiality of educational policy for higher education in the distance, through the offer of enrollment of public and private sectors. We work with the synopses of Higher Education from 2000 to 2009, of the Instituto Nacional de Estudos e Pesquisas Educacionais "Anísio Teixeira" (INEP), and also used as a technique for data collection, interviews and questionnaires with teachers and tutors of public and private. We note that there is a growing trend in enrollments in distance learning courses at the expense of growth in enrollment in the classroom teaching and, as a consequence, a qualitative change in the process of teaching, this one focusing on division particular of labor and new forms of contracts established pointing to its intensification and precarization.
An investigation into how EFL learners emotionally respond to teachers' oral corrective feedback

This research study draws on research in SLA and language pedagogy and hopes to throw some light on the pedagogical effectiveness of the oral feedback process in L2 classrooms by focusing exclusively on the potential affective damage that teachers´ oral corrective feedback can cause among learners in classroom settings. The paper describes a study in which we investigated how EFL learners actually perceive or rather emotionally respond to the oral feedback process. This paper aims to investigate to what extent the way teachers provide oral corrective feedback is somehow associated with learners´ motivations and attitudes. For this purpose, a short questionnaire was designed and distributed among a sample of 208 EFL secondary school learners. The article first reviews the literature on the controversial role of corrective feedback in L2 classrooms. Next, the findings are reported and discussed. This research paper suggests that EFL learners emotionally respond to teachers´ oral corrective feedback in different ways. Additionally, it found evidence that anxiety can have a negative effect on the way learners benefit from the oral feedback process. Thus, the paper issues warnings about the potential affective damage oral corrective feedback can cause among learners in classroom situations.
Randomized Strategy for Walking in Streets for a Simple Robot

We consider the problem of walking in an unknown street, for a robot that has a minimal sensing capability. The robot is equipped with a sensor that only detects the discontinuities in depth information (gaps) and can locate the target point as enters in its visibility region. First, we propose an online deterministic search strategy that generates an optimal search path for the simple robot to reach the target t, starting from s. In contrast with previously known research, the path is designed without memorizing any portion of the scene has seen so far. Then, we present a randomized search strategy, based on the deterministic strategy. We prove that the expected distance traveled by the robot is at most a 5.33 times longer than the shortest path to reach the target.
