Synchronized Output Regulation of Linear Networked Systems

This note addresses the problem of synchronized output regulation of linear networked system where all the nodes have their outputs track signals produced by the same exosystem and the state of exosystem is accessible only to leader nodes, while follower nodes regulate their outputs via a distributed synchronous protocol. This problem can be decoupled into two: one is the output regulation problem on the synchronous manifold and the other is the stability problem of synchronous manifold. The proposed synchronous protocol is independent of the network topology. The stability of synchronous manifold is analyzed through the permissible eigenvalue region and the requirements of information graph. Finally, a numerical example illustrates the efficacy of the presented results.
Learning dialogue dynamics with the method of moments

In this paper, we introduce a novel framework to encode the dynamics of dialogues into a probabilistic graphical model. Traditionally, Hidden Markov Models (HMMs) would be used to address this problem, involving a first step of hand-crafting to build a dialogue model (e.g. defining potential hidden states) followed by applying expectation-maximisation (EM) algorithms to refine it. Recently, an alternative class of algorithms based on the Method of Moments (MoM) has proven successful in avoiding issues of the EM-like algorithms such as convergence towards local optima, tractability issues, initialization issues or the lack of theoretical guarantees. In this work, we show that dialogues may be modeled by SP-RFA, a class of graphical models efficiently learnable within the MoM and directly usable in planning algorithms (such as reinforcement learning). Experiments are led on the Ubuntu corpus and dialogues are considered as sequences of dialogue acts, represented by their Latent Dirichlet Allocation (LDA) and Latent Semantic Analysis (LSA). We show that a MoM-based algorithm can learn a compact model of sequences of such acts.
Advances in Relay Networks: Performance and Capacity Analysis of Space-Time Analog Network Coding

We propose modified space-time-coding-based analog network coding (ANC) for multiple-relay network, termed space-time analog network coding (STANC). We present the performance and capacity analysis of the proposed network in terms of SER and ergodic capacity. We derive the closed-form expressions for the moment-generating function (MGF) of the equivalent signal-to-noise ratio (SNR) of the multiple-relay STANC network over independent and identically distributed (i.i.d.) Rayleigh, Nakagami, and Rician channels. Average SER of the system is evaluated using MGF-based approach. We further derive the approximate closed-form expressions of ergodic capacity. These expressions are simple and enable effective evaluation of the performance and capacity of STANC system.
“ Spin Images ”

The spin image is a surface representation technique that was initially introduced by Andrew E. Johnson in [1] and is used for surface matching and object recognition in 3-D scenes. Spin images encode the global properties of any surface in an object-oriented coordinate system rather than in a viewer-oriented coordinate system. Object-oriented coordinate systems are coordinate systems fixed on a surface or an object while viewer-oriented coordinate systems are based on the viewpoint of the observer of the surface. By using object-oriented coordinate systems, the description of a surface or an object is view-independent and it does not change as the viewpoint changes [3].
Evaluation of Sensory and in Vitro Cardio Protective Properties of Sardine ( Sardina pilchardus ): The Effect of Grilling and Brining

The aim of this study was to investigate the effect of grilling and brining on the sensory properties, the fillet fatty acid composition and the cardio-protective activity of sardine (Sardina pilchardus), studying the in vitro activity against Platelet-Activating-Factor (PAF) induced platelet aggregation. Sensory evaluation of grilled and brined sardine showed that grilled sardine had higher scores for the attributes: grilled fish, marine and fresh fish whereas brined sardine had higher scores for the attributes: salty, iodine, oily and bitter. Grilled sardine exhibited significantly increased fillet fatty acid content while the brined fish sample significantly decreased fatty acid levels. Polar lipids of all specimens (raw, grilled and brined) showed strong inhibitory activity against PAF action indicating that grilling and brining have not diminished the cardio-protective properties of sardine.
Improving linearity of a 5.2 GHz low power mixer in 0.18μm CMOS process by using Derivative Superposition method

This paper describes the design and implementation of a low power mixer improved its linearity. The mixer which have implemented is based on bulk-driven mixer which is known for its low power operation. On the other hand, that mixer has a demerit of poor linearity. The architecture of the proposed mixer employs DS (Derivative Superposition) method to achieve high linearity remaining in low power consumption. The proposed design has been fabricated using TSMC 0. 18μm CMOS process. The measured IIP3 shows 6.38 dBm. A conversion gain shows -7.49 dB, and power consumption of 3.54 mW.
Lipoic Acid-Dependent Oxidative Catabolism of α-Keto Acids in Mitochondria Provides Evidence for Branched-Chain Amino Acid Catabolism in Arabidopsis1

Lipoic acid-dependent pathways of α-keto acid oxidation by mitochondria were investigated in pea (Pisum sativum), rice (Oryza sativa), and Arabidopsis. Proteins containing covalently bound lipoic acid were identified on isoelectric focusing/sodium dodecyl sulfate-polyacrylamide gel electrophoresis separations of mitochondrial proteins by the use of antibodies raised to this cofactor. All these proteins were identified by tandem mass spectrometry. Lipoic acid-containing acyltransferases from pyruvate dehydrogenase complex and α-ketoglutarate dehydrogenase complex were identified from all three species. In addition, acyltransferases from the branched-chain dehydrogenase complex were identified in both Arabidopsis and rice mitochondria. The substrate-dependent reduction of NAD+ was analyzed by spectrophotometry using specific α-keto acids. Pyruvate- and α-ketoglutarate-dependent reactions were measured in all three species. Activity of the branched-chain dehydrogenase complex was only measurable in Arabidopsis mitochondria using substrates that represented the α-keto acids derived by deamination of branched-chain amino acids (Val [valine], leucine, and isoleucine). The rate of branched-chain amino acid- and α-keto acid-dependent oxygen consumption by intact Arabidopsis mitochondria was highest with Val and the Val-derived α-keto acid, α-ketoisovaleric acid. Sequencing of peptides derived from trypsination of Arabidopsis mitochondrial proteins revealed the presence of many of the enzymes required for the oxidation of all three branched-chain amino acids. The potential role of branched-chain amino acid catabolism as an oxidative phosphorylation energy source or as a detoxification pathway during plant stress is discussed.
Social Networks and the Identification of Peer Effects

There is a large and growing literature on peer effects in economics. In the current article, we focus on a Manski-type linear-in-means model that has proved to be popular in empirical work. We critically examine some aspects of the statistical model that may be restrictive in empirical analyses. Specifically, we focus on three aspects. First, we examine the endogeneity of the network or peer groups. Second, we investigate simultaneously alternative definitions of links and the possibility of peer effects arising through multiple networks. Third, we highlight the representation of the traditional linear-in-means model as an autoregressive model, and contrast it with an alternative moving-average model, where the correlation between unconnected individuals who are indirectly connected is limited. Using data on friendship networks from the Add Health dataset, we illustrate the empirical relevance of these ideas.
Complementary expression of EphA7 and SCO-spondin during posterior commissure development

Bilaterally symmetric organisms need to exchange information between the two sides of their bodies in order to integrate sensory inputs and coordinate motor control. This exchange occurs through commissures formed by neurons that project axons across the midline to the contralateral side of the central nervous system. The posterior commissure is the first transversal axonal tract of the embryonic vertebrate brain. It is located in the dorsal portion of the prosomere 1, at the caudal diencephalon. The axons of the posterior commissure principally come from neurons of ventrolateral and dorsolateral pretectal nuclei (parvocellular and magnocellular nucleus of the posterior commissure, respectively) that extend their axons toward the dorsal region. The trajectory of these axons can be divided into the following three stages: (1) dorsal axon extension towards the lateral roof plate; (2) fasciculation in the lateral roof plate; and (3) midline decision of turning to the ipsilateral side or continuing to the opposite side. The mechanisms and molecules that guide the axons during these steps are unknown. In the present work, immunohistochemical and in situ hybridization analyses were performed, with results suggesting the participation of EphA7 in guiding axons from the ventral to the dorsal region of the prosomere 1 through the generation of an axonal corridor limited by repulsive EphA7 walls. At the lateral roof plate, the axons became fasciculated in presence of SCO-spondin until reaching the midline. Finally, EphA7 expression was observed in the diencephalic midline roof plate, specifically in the region where some axons turn to the ipsilateral side, suggesting its participation in this decision. In summary, the present work proposes a mechanism of posterior commissure formation orchestrated by the complementary expression of the axon guidance cues SCO-spondin and EphA7.
Biology and epidemiology of bacterial wilt caused by pseudomonas solanacearum.

Bacterial wilt caused by Pseudomonas solanacearum is widely distributed in tropical, subtropical and some warm temperate regions of the world, and is a major constraint on production of many crop plants. Major sections of this review are on: phylogeny (particularly using molecular biology), properties, relationships and geographical distribution; host range; modes of dispersal and sources of inoculum (including root-to-root transmission, movement of soil and dissemination by farm implements, and insect transmission); some environmental interactions (temperature - the most important factor affecting the host-pathogen interaction as well as survival in soils, light intensity, soil moisture (preferably high), soil type, and synergism with nematodes); and control strategies, especially development of host-plant resistance, appropriate cropping systems, soil amendment, disease avoidance, integrated control, and biological control using antagonistic rhizobacteria and avirulent mutants. -P.J.Jarvis

B2T Electronic Commerce Model's Influence on Mass Customization

B2T electronic commerce model is Internet-based group-buying model. Consumers with the same demand may accumulate rapidly through the Internet. B2T electronic commerce model provides accurate demand to mass customization which is the premise of the implementation of the custom value; from another point of view, the scale effect bought by group-buying reduces the cost of mass customization. This paper mainly from custom value and custom cost these two aspects to conduct the research of the influence of B2T electronic commerce model.

Clinical Pharmacology: Advances and Applications Dovepress Pharmacokinetics and Outcome of Tazobactam/ Piperacillin in Japanese Patients Undergoing Low-flow Continuous Renal Replacement Therapy: Dosage Considerations

you hereby accept the Terms. Non-commercial uses of the work are permitted without any further permission from Dove Medical Press Limited, provided the work is properly attributed. For permission for commercial use of this work, please see paragraphs 4.2 and 5 of our Terms Background: Tazobactam/piperacillin (TAZ/PIPC), which is often combined with continuous renal replacement therapy (CRRT), induces renal excretion and is thought to have a high component removal rate for blood purification. CRRT procedures vary depending on the country, region, and institution. It is not clear whether the dose of TAZ/PIPC for use in Japan can be determined based on studies conducted in other countries. Therefore, in this study, we examined the suitability of recommended dose in Japan. Methods: The study subjects consisted of 10 patients who received TAZ/PIPC during CRRT in the intensive care unit of Hyogo College of Medicine, Nishinomiya, Japan. We used a one-compartment model to characterize and parameterize the pharmacokinetics of TAZ/PIPC because their blood levels were eliminated monoexponentially. Results: Compared with the data of healthy adults, the half-lives (t 1/2) of both PIPC and TAZ were prolonged while their clearance rates decreased. Conclusion: For the continuous hemodiafiltration procedure adopted in Japan, we concluded that the dose and frequency were appropriate because the patients who received PIPC/TAZ 2.25 g twice a day during continuous hemodiafiltration maintained appropriate blood levels of both PIPC and TAZ.
When place and time matter: How to conduct safe inter-hospital transfer of patients

Inter-hospital transfer (IHT) of patients is often needed for diagnostic or therapeutic interventions. However, the transfer process carries its own risks as a poorly and hastily conducted transfer could lead to adverse events. In this article, we have reviewed literature on the key elements of IHT process including pre-transfer patient stabilization. We have also discussed various modes of transfer, physiological effects of transfer, possible adverse events and how to avoid or mitigate these. Even critically ill-patients can be transported safely by experienced and trained personnel using appropriate equipment. The patient must be maximally stabilized prior to transfer though complete optimization may be possible only at the receiving hospital. Ground or air transport may be employed depending on the urgency, feasibility and availability. Meticulous pre-transfer check and adherence to standard protocols during the transfer will help keep the entire process smooth and event free. The transport team should be trained to anticipate and manage any possible adverse events, medical or technical, during the transfer. Coordination between the referring and receiving hospitals would facilitate prompt transfer to the definitive destination avoiding delay at the emergency or casualty. Documentation of the transfer process and transfer of medical record and investigation reports are important for maintaining continuity of medical care and for medico-legal purposes.

POPULATION This recommendation applies to adults aged 18 years or older without known hypertension. RECOMMENDATION The USPSTF recommends screening for high blood pressure in adults aged 18 years or older. (A recommendation) The USPSTF recommends obtaining measurements outside of the clinical setting for diagnostic confirmation before starting treatment.
Improving tensile strength and moisture barrier properties of gelatin using microfibrillated cellulose

Microfibrillated cellulose isolated from bagasse was used to prepare novel nanocomposites using cross-linked gelatin as a biodegradable polymer matrix. Microfibrillated cellulose loadings up to 25% (weight percent) were used. The prepared nanocomposites were characterized regarding their wet and dry tensile strength, water sorption, and water vapor permeability. Nanocomposites’ surfaces were examined by scanning electron microscopy; the scanning electron microscopy images indicated homogeneous distribution of microfibrillated cellulose in the gelatin matrix. Microfibrillated cellulose improved wet and dry maximum tensile stress and modulus of cross-linked gelatin but resulted in a decrease of its strain at break. Microfibrillated cellulose did not affect the water absorption of cross-linked gelatin but significantly improved its moisture barrier property.
Matching sets of parse trees for answering multi-sentence questions

The problem of answering multi-sentence questions is addressed in a number of products and services-related domains. A candidate set of answers, obtained by a keyword search, is re-ranked by matching the set of parse trees of an answer with that of the question. To do that, a graph representation and learning technique for parse structures for paragraphs of text have been developed. Parse Thicket (PT) as a set of syntactic parse trees augmented by a number of arcs for inter-sentence word-word relations such as co-reference and taxonomic relations is introduced. These arcs are also derived from other sources, including Speech Act and Rhetoric Structure theories. The proposed approach is subject to evaluation in the product search and recommendation domain, where search queries include multiple sentences. An open source plugin for SOLR is developed so that the proposed technology can be easily integrated with industrial search engines.
A metal-oxide-semiconductor varactor

CMOS technology scaling opens up the possibility of designing variable capacitors based on a metal oxide semiconductor structure with improved tuning range and quality factor. This is due to an increase in the oxide capacitance and a reduction in the parasitic resistance. A prototype metal-oxide-semiconductor (MOS) variable capacitor of 3.1 pF nominal value has been realized in a 0.35-/spl mu/m standard CMOS process. A factor two capacitance change has been achieved for a 2-V variation of the controlling voltage. The varactor Q ranges from 17 to 35, at 1.8 GHz.
Endothelial Progenitor Cell Vascular Endothelial Growth Factor Gene Transfer for Vascular Regeneration

Background—Previous studies have established that bone marrow–derived endothelial progenitor cells (EPCs) are present in the systemic circulation. In the current study, we investigated the hypothesis that gene transfer can be used to achieve phenotypic modulation of EPCs. Methods and Results—In vitro, ex vivo murine vascular endothelial growth factor (VEGF) 164 gene transfer augmented EPC proliferative activity and enhanced adhesion and incorporation of EPCs into quiescent as well as activated endothelial cell monolayers. To determine if such phenotypic modulation may facilitate therapeutic neovascularization, heterologous EPCs transduced with adenovirus encoding VEGF were administered to athymic nude mice with hindlimb ischemia; neovascularization and blood flow recovery were both improved, and limb necrosis/autoamputation were reduced by 63.7% in comparison with control animals. The dose of EPCs used for the in vivo experiments was 30 times less than that required in previous trials of EPC transplantation to improve ischemic limb salvage. Necropsy analysis of animals that received DiI-labeled VEGF-transduced EPCs confirmed that enhanced EPC incorporation demonstrated in vitro contributed to in vivo neovascularization as well. Conclusions—In vitro, VEGF EPC gene transfer enhances EPC proliferation, adhesion, and incorporation into endothelial cell monolayers. In vivo, gene-modified EPCs facilitate the strategy of cell transplantation to augment naturally impaired neovascularization in an animal model of experimentally induced limb ischemia.
Satisfiability of equations in free groups is in PSPACE

We prove that the computational complexity of the problem of deciding if an equation in a free group has a solution is PSPACE. The problem was proved decidable in 1982 by Makanin, w h o s e algorithm was proved later to be non primitive recursive: this was the best upper bound known for this problem. Our proof consists in reducing equations in free groups to equations in free semigroups with antiinvolution, and presenting an algorithm for deciding equations in free semigroups with antiinvolution.
Augmented Panoramic Video

Many video sequences consist of a locally dynamic background containing moving foreground subjects. In this paper we propose a novel way of re‐displaying these sequences, by giving the user control over a virtual camera frame. Based on video mosaicing, we first compute a static high quality background panorama. After segmenting and removing the foreground subjects from the original video, the remaining elements are merged into a dynamic background panorama, which seamlessly extends the original video footage. We then re‐display this augmented video by warping and cropping the panorama. The virtual camera can have an enlarged field‐of‐view and a controlled camera motion. Our technique is able to process videos with complex camera motions, reconstructing high quality panoramas without parallax artefacts, visible seams or blurring, while retaining repetitive dynamic elements.
Structure, Strength and Ductility of As-Cast Al-Mg-Mn-Zr-Sc Alloys after Equal Channel Angular Pressing

The effect of equal channel angular pressing (ECAP) on the structure and mechanical properties of Al-4% Mg-1.5% Mn-0.4% Zr and Al-4% Mg-1.5% Mn-0.4% Zr-0.4% Sc alloys in the initial as-cast state was studied. The ECAP processing was shown to lead to the formation of predominantly submicrocrystalline structure with an average grain size of 850 nm in the Al-Mg-Mn-Zr-Sc alloy and 1060 nm in the Al-Mg-Mn-Zr alloy. It is remarkable that both strength and ductility of the two alloys were enhanced by ECAP. The highest strength was observed in the Al–Mg–Mn–Zr–Sc alloy (UTS = 425MPa), in combination with elongation to failure of EL=17 %.
