We will give a formula to compute the regularity index of s + 2 fat points not lying on a linear (s - 1)-space in ℙ n, s ≤ n (Theorem 3.4). Our result generalizes a formula to compute the regularity index of fat points in general position in ℙ n ([3], Corollary 8). Our result also shows that the Segre bound is attained by s + 2 points not lying on a linear (s - 1)-space. © 2012 Copyright Taylor and Francis Group, LLC.

Simultaneous integration of multifunctional properties from different components into a hybrid nanostructure with hierarchical organization is attractive to construct new materials sought for diverse useful applications. This review highlights recent advances in the fabrication of multicomponent organic-conjugated inorganic nanoarchitectures and their potential uses in optical sensing and diagnostic tools. The similarity of the particle sizes, between inorganic hybrids and biomolecules, is the reason they can integrate into new bioconjugated nanocomposites. These multifunctional properties enable such materials to function as dual diagnostic and therapeutic agents in imaging-guided therapy. Deoxyribonucleic acid (DNA)-templated replica approaches for fabricating DNA-functionalized plasmonic nanoarchitectures are discussed to show how incorporation of metal clusters onto helical DNA structures occurs. The resulting helix plasmonic assemblies response enhanced plasmonic properties and circular dichroism signals to external environments, means they can function as highly selective bioprobes. Nanocrystal superlattices are prepared by assembling the uniform colloids by guiding the external magnetic field and solvent evaporation. The highly organized superlattices with long-range ordering exhibit optical properties tuned by external stimuli and, consequently they can be useful for desirable optical sensors and photoswitchable patterns. The efforts discussed in this review are expected to present the structural diversity of promising multifunctional nanoarchitectures for the design of efficient optical sensing and diagnostic tools. © The Royal Society of Chemistry 2014.

Several researchers conducted studies to demonstrate the use of fluoro- and chromogenic chemodosimeters for heavy metal ion detection in solution and biospecimens. They demonstrated that fluorescent chemodosimeters had emerged as as a research area of significant importance due to their potential in detecting heavy metal ions in solution and biospecimens. Chemodosimeters were used to detect an analyte through a highly selective and irreversible chemical reaction between the dosimeter molecule and the target analyte. This led to an observable signal that had an accumulative effect and was directly related to the concentration of the analyte. The chemodosimeter also provided signaling changes in absorption wavelength and color that were widely used as detection events, as they required only the use of cost-effective equipment or no equipment in some cases.

Whether or not fishers comply with regulation depends on the economic and social context in which they operate their vessels. This is how conventional theory explains the phenomenon of non-compliance. It treats state-community interaction processes not as direct causes for non-compliance but rather as background conditions shaping individual fishers' perception and decisions for action. This paper argues that conventional theory fails to include the dynamics of tempo-relational processes between state and communities, which explains collective patterns of non-compliance in fisheries. The paper addresses this hiatus in the literature, using a process-sociological approach to analyse non-compliance in Vietnamese marine fisheries. The analysis highlights that Vietnamese marine fisheries are mainly regulated through informal networks of trust and mistrust, which function through their interplay with the highly centralised and formalised Vietnamese state. Based on this assessment, the paper concludes that outcomes of processes of the dynamic social interplay between state and communities are semi-dependent on individual perception and action, and as such have a causal effect of their own on patterns of non-compliance in fisheries. © 2010.

We propose a new method to adaptive object detector is to incorporate the scene specific information without human intervention to reach the goal of fully autonomous surveillance where the focus is on developing adaptive approaches for object detection from single and multiple stationary cameras that are able to incorporate unlabeled information using different types of context in order to collect scene specific samples from both, the background and the object class over time. The main contributions of this paper tackle the question of how to incorporate prior knowledge or scene specific information in an unsupervised manner. Thus, the goal of this work is to increase the recall of scene-specific classifiers while preserving their accuracy and speed. In particular, we introduce a co-training strategy for classifier grids using a robust on-line learner. The system runs at 24 h per day and 7 days per week with 24 frames per second on consumer hardware. Our evaluation show high accuracy on both synthetic and real test sets. We achieve state of the art in our comparisons with related work and in the experimental results these benefits are demonstrated on different publicly available surveillance benchmark data sets. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2016.

Gestures, a natural language of humans, provide an intuitive and effortless interface for communication with the computers. However, the achievements do not satisfy researcher’s demands because of the complexity and instability of human gestures. We propose a new method to recognize gestures from sound waves. The main contribution of this paper is to recognize gestures based on the analysis of short-time Fourier transforms (STFT) using the Doppler effect to sense gestures. To do this, we generate an inaudible tone, which gets frequency shifted when it reflects off moving objects like the hand. We measure this shift with the microphone to infer various gestures. Experimenting method and evaluating results by using the hand gestures of many different people to browse applications such as website, document and images in the browser on the computers in the classroom and library environment for accurate results. In addition, we describe the phenomena and recognition algorithm, demonstrate a variety of gestures, and present an informal evaluation on the robustness of this approach across Laptop device and people. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2016.

Four cattle calves (Boss indicus) of average weight 120. kg and four swamp buffaloes calves of average weight 220. kg were fed four rice straw diets in a Latin square design. The rice straw were sprayed with 0%, 0.5%, 1% and 2% of urea and given ad libitum. Each period was 15 days during the last 5 days of which urine and faeces were collected. Urine samples were analysed for excretion of purine derivatives (PD) to measure microbial protein production.There was no significant effect on intake of rice straw which was 3.1, 3.4, 3.1 and 3.1 kgDM/day for cattle and 4.5, 4.5, 4.5 and 4.6kgDM/day for buffalo. Rumen NH3 concentrations were 39, 60, 70 and 96mg/l for cattle and 51, 81, 102 and 132mg/l for buffalo with significant difference. However the PD excretion in the urine was not significantly changed being 0.28, 0.19, 0.18 and 0.23mmol/kgW0.75 for cattle and as expected lower for buffaloes being 0.13, 0.11, 0.12 and 0.11mmol/kgW0.75. The dry matter digestibilities for cattle were 57.1, 60.3, 58.3 and 60.7 while for buffalo the digestibilities were 60.7, 57.4, 59.6 and 60.2.The results suggest that the rice straw containing 6% protein and digestibility between 57% and 60% provided sufficient crude protein for microbial needs. © 2012 Elsevier B.V.

Aqueous-dispersed single and binary noble metal nanocrystals have attracted much attention as key materials in many fields, especially in biomedicine, catalysis, etc. Controlled growth of the metal nuclei allow for the manipulation of uniform morphology of final products. This behavior would tailor their unique physiochemical and electronic properties and follows by their practical applications. This review presents an overall picture of kinetic formation of a particle and then summarizes an overview of recent progress in many research groups concerning aqueous- and/or polyol-based syntheses of many types of aqueous-dispersed single metallic and bimetallic nanocrystals with controlled shape. The main advantages in these synthetic approaches for the shape-controlled metal nanocrystals are simple, versatile, environmentally friendly, low cost, pure and single-crystalline products, and high yield. The formed products can be easily dispersed in water medium and compatible for biotechnological field. Particularly the biomolecule (antibody including protein and/or DNA)-conjugated gold nanocrystals have been utilized as an active agent for a broad range of biomedical applications. We expect that this review will have a high potential towards novel materials fabrication and nanotechnological fields. © 2011.

Can, and under which conditions, the 125-GeV SM-like scalar with the signal strengths for its decays into W+W-, ZZ, γγ, bb- and ττ- being consistent with experiments be accommodated in models that go beyond the Standard Model? Is it truly what it appears to be, namely the SM Higgs boson, or could it be quite different? A minimal extension of the original electroweak-scale right-handed neutrino model, in which right-handed neutrinos naturally obtain electroweak-scale masses, shows a scalar spectrum which includes either the 125-GeV SM-like scalar or a scalar which is quite unlike that of the Standard Model, both of which possess signal strengths compatible with experiment. In other words, the 125-GeV scalar could be an impostor. © 2015 The Authors.
