Algebraic Aspects of Reconstruction of Structured Scenes from One or More Views

This paper considers the problem of 3D reconstruction from 2D points in one or more images and auxiliary information about the corresponding 3D features : alignments, coplanarities, ratios of lengths or symmetries are known. Our £rst contribution is a necessary and suf£cient criterion that indicates whether a dataset, or subsets thereof, de£nes a rigid reconstruction up to scale and translation. Another contribution is a reconstruction method for one or more images. We show that the observations impose linear constraints on the reconstruction. All the input data, possibly coming from many images, is summarized in a single linear system, whose solution yields the reconstruction. The criterion which indicates whether the solution is unique up to scale and translation is the rank of another linear system, called the “twin” system. Multiple objects whose relative scale can be arbitrarily chosen are identi£ed. The reconstruction is obtained up to an af£ne transformation, or, if calibration is available, up to a Euclidean transformation.
An Analytical Solution to the Kinetics of Breakable Filament Assembly

Dissecting Amyloid Formation Amyloid fibrils are associated with clinical disorders ranging from Alzheimer's disease to type II diabetes. Their self-assembly can be described by a master equation that takes into account nucleation-dependent polymerization and fragmentation. Knowles et al. (p. 1533) now present an analytical solution to the master equation, which shows that amyloid growth kinetics is often limited by the fragmentation rate rather than by the rate of primary nucleation. In addition, the results reveal relationships between system properties (scaling laws) that provide mechanistic insight not only into amyloid growth, but also into related self-assembly processes. The growth kinetics of amyloid fibrils and related self-assembly phenomena are revealed by analytical theory. We present an analytical treatment of a set of coupled kinetic equations that governs the self-assembly of filamentous molecular structures. Application to the case of protein aggregation demonstrates that the kinetics of amyloid growth can often be dominated by secondary rather than by primary nucleation events. Our results further reveal a range of general features of the growth kinetics of fragmenting filamentous structures, including the existence of generic scaling laws that provide mechanistic information in contexts ranging from in vitro amyloid growth to the in vivo development of mammalian prion diseases.
NEGF analysis of current oscillation in Germanium nanowire MOSFETs

In this paper, the quantum transport of a Germanium based Gate-All-Around NanoWire Transistor, GAANWT is simulated in nanoscale regime. We have implemented a 3D ballistic simulator based on the Non-Equilibrium Green Function, NEGF, formalism within the effective mass approximation and the mode space approach. Due to low effective mass of the Germanium, it is a promising channel material in nanoscale regime. The size quantization in the nanowires results in the formation of the discrete energy levels along the channel. We have comprehensively investigated key parameters that may affect the normal performance of the Ge based NWT. Simulation results reveal that the current oscillations are observable in the transfer characteristic at the low temperature and drain voltages. It's observed that these oscillations strongly depending upon the channel thickness in such a way that for thick channels, are visible only at low temperatures. As the channel thickness scales down to 4nm, the oscillations are apparent even at room temperature. The drain current oscillations are gradually disappeared as the drain voltage increases.
Dynamic configuration of mobile cloud middleware based on traffic load

The increasing demand of the mobile applications for processing power, storage space and energy saving have led them in adapting the cloud. To ease the offloading of these resource-intensive activities to the cloud, we have developed the Mobile Cloud Middleware (MCM), which also helps in combining services from multiple clouds. While MCM is shown to be horizontally scalable, the dynamic loads of telecommunication networks demand for identifying ideal topology and hot re-configuration of the deployment. The paper proposes the characteristics to be considered for identifying the topology and using concurrent languages like Erlang for adapting the topology dynamically.
MinE conformational dynamics regulate membrane binding, MinD interaction, and Min oscillation

Significance The Min system is a well-studied biological oscillator that consists of MinC, MinD, and MinE. MinE assembles into a ring that drives a pole-to-pole oscillation of the FtsZ antagonist MinC/MinD to ensure positioning of the Z ring at midcell. To do this, MinE undergoes a remarkable conformational switch, but how it does this is not clear. Here, we use intragenic suppressors of a MinE mutant along with hydrogen–deuterium exchange to elicit the pathway for the conformational switch. The results lead to a multistep model that involves MinD and engenders an appreciation for how the MinE structure is fine-tuned to switch between a form that diffuses in the cytoplasm and a form that binds the membrane and, ultimately, MinD. In Escherichia coli MinE induces MinC/MinD to oscillate between the ends of the cell, contributing to the precise placement of the Z ring at midcell. To do this, MinE undergoes a remarkable conformational change from a latent 6β-stranded form that diffuses in the cytoplasm to an active 4β-stranded form bound to the membrane and MinD. How this conformational switch occurs is not known. Here, using hydrogen–deuterium exchange coupled to mass spectrometry (HDX-MS) we rule out a model in which the two forms are in rapid equilibrium. Furthermore, HDX-MS revealed that a MinE mutant (D45A/V49A), previously shown to produce an aberrant oscillation and unable to assemble a MinE ring, is more rigid than WT MinE. This mutant has a defect in interaction with MinD, suggesting it has difficulty in switching to the active form. Analysis of intragenic suppressors of this mutant suggests it has difficulty in releasing the N-terminal membrane targeting sequences (MTS). These results indicate that the dynamic association of the MTS with the β-sheet is fine-tuned to balance MinE’s need to sense MinD on the membrane with its need to diffuse in the cytoplasm, both of which are necessary for the oscillation. The results lead to models for MinE activation and MinE ring formation.
Performance Analysis of MIMO-MRC Systems With Channel Estimation Error in the Presence of Cochannel Interferences

In this letter, we analyze the performance of multiple-input multiple-output (MIMO) wireless communications with transmit beamforming and maximum ratio combining (MRC), known as MIMO-MRC, with channel estimation error in the presence of cochannel interferences (CCIs). The quantified measure for channel estimation error is the correlation coefficient between the true fading channel coefficients and their estimates. Exact closed-form expressions for the statistical distribution of the signal-to-noise-plus-interference ratio (SINR), the outage probability of the SINR, and the average symbol error rate (ASER) for some modulation formats are derived. The analytical results are confirmed by numerical simulations.

A Mechanism of Nonphotochemical Energy Dissipation, Independent from PsbS, Revealed by a Conformational Change in the Antenna Protein CP26w⃞

The regulation of light harvesting in higher plant photosynthesis, defined as stress-dependent modulation of the ratio of energy transfer to the reaction centers versus heat dissipation, was studied by means of carotenoid biosynthesis mutants and recombinant light harvesting complexes (LHCs) with modified chromophore binding. The npq2 mutant of Arabidopsis thaliana, blocked in the biosynthesis of violaxanthin and thus accumulating zeaxanthin, was shown to have a lower fluorescence yield of chlorophyll in vivo and, correspondingly, a higher level of energy dissipation, with respect to the wild-type strain and npq1 mutant, the latter of which is incapable of zeaxanthin accumulation. Experiments on purified thylakoid membranes from all three mutants showed that the major source of the difference between the npq2 and wild-type preparations was a change in pigment to protein interactions, which can explain the lower chlorophyll fluorescence yield in the npq2 samples. Analysis of the xanthophyll binding LHC proteins showed that the Lhcb5 photosystem II subunit (also called CP26) undergoes a change in its pI upon binding of zeaxanthin. The same effect was observed in wild-type CP26 upon treatment that leads to the accumulation of zeaxanthin in the membrane and was interpreted as the consequence of a conformational change. This hypothesis was confirmed by the analysis of two recombinant proteins obtained by overexpression of the Lhcb5 apoprotein in Escherichia coli and reconstitution in vitro with either violaxanthin or zeaxanthin. The V and Z containing pigment-protein complexes obtained by this procedure showed different pIs and high and low fluorescence yields, respectively. These results confirm that LHC proteins exist in multiple conformations, an idea suggested by previous spectroscopic measurements (Moya et al., 2001), and imply that the switch between the different LHC protein conformations is activated by the binding of zeaxanthin to the allosteric site L2. The results suggest that the quenching process induced by the accumulation of zeaxanthin contributes to qI, a component of NPQ whose origin was previously poorly understood.
Early Childhood Psychosis: Infantile Autism, Childhood Schizophrenia and Related Disorders. An Annotated Bibliography 1964 to 1969.

s are given for 346 publications on childhood schizophrenia-from 1955 to 1964. The bibliography is divided into 7 sections: historical and general review, description and diagnosis, etiology, biochemical-neurological-physiological studies, family characteristics, treatment and care, and follow-up studies. 27. Treffert, C. A. The epidemiology of infantile autism. Presented at the American Psychiatric Association, 1969. Prevalence rates of childhood schizophrenia were determined for the entire Wisconsin state population of CA 12 yrs. and under. The sample was divided into 3 groups: (1) classic infantile autism, (2) other variants of childhood schizophrenia, and (3) probable psychosis with evidence of brain damage. Of the 3.4 cases per 10,000 population, 25% were in group 1, 50% in group 2, and 25% in grou7 1. The male:female ratio was approximately 4:1. 28. van Krevelen, D. ; Spiel, W. ; von Stockert, F.

Concepts of early infantile autism are reviewed and four diagnostic criteria are suggested:, lack of object relations, lack of use of speech for communication, maintenance of sameness via stereotypic behavior, and lack of neurologic dysfunction. Two subgroups, organic and psychogenic, were described, but neither group was reported to respond very successfully to treatment except when a very active, intrusive and pleasant therapeutic approach was used. The author presents his own view of psychogenic autism which is seen as resulting from a lack of varying, novel and patterned stimulation in the early developmental history, leading to a deviant style of ego development and the formation of a behavioral ego rather than a true body image.
MMSE Hybrid Beamforming for Weighted Sum Rate Maximization in NOMA Systems

This work proposes a multiuser hybrid beamforming scheme for non-orthogonal multiple access (NOMA) systems using the minimum mean square error (MMSE) approach to weighted sum rate maximization. While NOMA may be effective in terms of enhancing user fairness, hybrid beamforming is necessary to reduce the transceiver cost as the system moves towards higher frequency. The design is divided into two stages. In the first stage, a fully digital multiuser beamformer is derived by maximizing the weighted sum rate of all users under no constraint on the number of RF chains. This problem is then transformed into a weighted sum MSE minimization problem, which facilitates the use of alternating optimization to obtain an efficient local solution. In the second stage, the previously obtained multiuser beamformer is then split into RF and baseband beamformers by using orthogonal matching pursuit (OMP). A user role selection algorithm is then proposed to determine the role of strong and weak users. Simulation results are provided to demonstrate the effectiveness of the proposed schemes.
A FPGA-based parallel semi-naive Bayes classifier implementation

: Recently, use of high-throughput data with high-dimensional feature space such as images and microarrays have increased signiﬁcantly. Therefore, a fast and eﬃcient method to process these data is required. In this paper, we propose a novel semi-naive Bayes classiﬁcation method based on stochastic discrimination theory and implement it in hardware. The hardware implemented on a FPGA with massively parallel computation enables fast and eﬃcient processing, because the algorithm of the proposed method is very suitable for parallel computation. The implemented hardware takes 0.378 µ s at 106 MHz clock to process given one test data. In addition, we evaluate the performance of the proposed method through experiments on various datasets. In the experimental results, our proposed method shows competitive performance compared with conventional machine learning methods.
Influence of moonlight and gonotrophic age on biting activity of Anopheles farauti (Diptera: Culicidae) from Papua New Guinea.

All-night man-biting collections of Anopheles farauti s.l. were made in a village in coastal Papua New Guinea in August and September 1982. A total of 10,827 mosquitoes were collected, and 6,293 of these were dissected for parity determination. The biting cycle varied according to moon phase, with more mosquitoes collected during the moonlit hours of the night. Parous mosquitoes also had a different biting cycle than nulliparous ones, but there was no interactive effect between age and moonlight. The overall number of mosquitoes biting was lower during moonless nights compared to nights when the moon was rising or full. A similar result was obtained in 1983 when 22,550 mosquitoes were collected over a 10-wk period from August to October. The proportion of human-fed females among engorged specimens collected while resting increased during moonless periods.
Design of synthesis filter banks for the structural similarity index

The optimal synthesis filter bank (FB) is designed for a given analysis FB by using the structural similarity (SSIM) criteria. Under the assumption that the source signal is a wide sense stationary (WSS) process with known power spectral density (PSD), that the noise is Gaussian white, and that the filter length is equal to the decimation number, the optimization problem is formulated. The closed-form solution is obtained when the mean of the source is zero. It is shown that the optimal FB designed by SSIM criteria and the one by mean square error (MSE) criteria differs only from a scalar factor. Finally, numerical example is given to compare the performance of different synthesis FBs.
Robust control under weakened real-time constraints

A weakened implementation scheme for real-time feedback controllers is proposed to reduce the conservatism due to traditional worst-cases considerations, while preserving the stability and control performance. Based on recent results to assess stability of linear systems with delayed and sampled-data inputs, this paper takes into account both the effects of deadline misses of control tasks and uncertainties in the plant. The methodology is applied to the pitch control of an aircraft, showing that weakening the real-time constraints allows for saving computing power while preserving the system's stability.
Kernel based classifiers fusion with features diversity for breast masses classification

This paper investigated a computer-aided diagnosis for breast mass classification by mammography examination using complementarity existing between features and classifiers. It is concerned with the design and development of an automatic mass classification of mammograms. The proposed method consists of three stages: segmentation, feature extraction and classification. In classification phase, kernel based classifiers combination is a current active paradigm in the field of machine learning. It takes benefit of classification fusion algorithms. The combination of Kernel-based classifiers was proposed as a research way allowing recognition reliability by using diversity which can be exist between classifiers. The proposed scheme is based on combination of support vector machine classifiers. Each one is associated with an homogenous family of features (Hu moments; central moments, Haralick moment. Diversity criteria between features are adopted in this study to ensure best performance. Our experiments demonstrated that developed system using (DDSM) database achieve very encouraging results.
Inhibition of cholinesterase and amyloid‐β aggregation by resveratrol oligomers from Vitis amurensis

In the course of screening for acetylcholinesterase and butyrylcholinesterase inhibitors from natural products by an in vitro Ellman method, the extract of the roots of Vitis amurensis Rupr. (Vitaceae) showed significant cholinesterase inhibitory activity. Employing a bioassay‐linked HPLC method, followed by a semi‐preparative HPLC method, two compounds of interest were isolated and characterized as vitisin A and heyneanol A. They inhibited effectively both acetylcholinesterase and butyrylcholinesterase in a dose‐dependent manner and exhibited higher activity against butyrylcholinesterase compared with that of galantamine, a positive control. Furthermore, the aggregation of β‐amyloid was evaluated in vitro based on a thioflavine T fluorescence assay to expand their activity profile, with the result that both compounds showed the ability to block β‐amyloid aggregation.

Hemodynamic, renal, and hormonal effects of adrenomedullin infusion in patients with congestive heart failure.

BACKGROUND Experimental studies have shown that adrenomedullin (AM) causes vasodilatation, diuresis, and a positive inotropic effect. In humans, however, whether infusion of AM has beneficial effects in congestive heart failure (CHF) remains unknown. METHODS AND RESULTS Hemodynamic, renal, and hormonal responses to intravenous infusion of human AM (0.05 microg. kg(-1). min(-1)) were examined in 7 patients with CHF and 7 normal healthy subjects (NL). In NL group, AM significantly decreased mean arterial pressure (-16 mm Hg, P<0. 05) and increased heart rate (+12 bpm, P<0.05). In CHF group, AM also decreased mean arterial pressure (-8 mm Hg, P<0.05) and increased heart rate (+5 bpm, P<0.05), but to a much lesser degree (P<0.05 versus NL). AM markedly increased cardiac index (CHF, +49%; NL, +39%, P<0.05) while decreasing pulmonary capillary wedge pressure (CHF, -4 mm Hg; NL, -2 mm Hg, P<0.05). AM significantly decreased mean pulmonary arterial pressure only in CHF (-4 mm Hg, P<0.05). AM increased urine volume (CHF, +48%; NL, +62%, P<0.05) and urinary sodium excretion (CHF, +42%; NL, +75%, P<0.05). Only in CHF, plasma aldosterone significantly decreased during (-28%, P<0.05) and after (-36%, P<0.05) AM infusion. These parameters remained unchanged in 7 patients with CHF and 6 healthy subjects who received placebo. CONCLUSIONS Intravenous infusion of AM has beneficial hemodynamic and renal effects in patients with CHF.
One Health research and training and government support for One Health in South Asia

Introduction Considerable advocacy, funding, training, and technical support have been provided to South Asian countries to strengthen One Health (OH) collaborative approaches for controlling diseases with global human pandemic potential since the early 2000s. It is essential that the OH approach continues to be strengthened given South Asia is a hot spot for emerging and endemic zoonotic diseases. The objectives of this article are to describe OH research and training and capacity building activities and the important developments in government support for OH in these countries to identify current achievements and gaps. Materials and methods A landscape analysis of OH research, training, and government support in South Asia was generated by searching peer-reviewed and grey literature for OH research publications and reports, a questionnaire survey of people potentially engaged in OH research in South Asia and the authors’ professional networks. Results Only a small proportion of zoonotic disease research conducted in South Asia can be described as truly OH, with a significant lack of OH policy-relevant research. A small number of multisectoral OH research and OH capacity building programmes were conducted in the region. The governments of Bangladesh and Bhutan have established operational OH strategies, with variable progress institutionalising OH in other countries. Identified gaps were a lack of useful scientific information and of a collaborative culture for formulating and implementing integrated zoonotic disease control policies and the need for ongoing support for transdisciplinary OH research and policy-relevant capacity building programmes. Discussion Overall we found a very small number of truly OH research and capacity building programmes in South Asia. Even though significant progress has been made in institutionalising OH in some South Asian countries, further behavioural, attitudinal, and institutional changes are required to strengthen OH research and training and implementation of sustainably effective integrated zoonotic disease control policies.
