Path-Based Dynamic Voltage and Frequency Scaling Algorithms for Multiprocessor Embedded Applications with Soft Delay Deadlines

This paper introduces four path-based DVFS algorithms for embedded multimedia applications. Application model consists of multiprocessor scheduled task-graphs and input class probability distributions. Design constraints are a soft delay deadline and a minimum completion ratio. The algorithms target four scenarios that correspond to systems with various DVFS and quality of service monitoring capabilities. In the first scenario, all inputs must be timely processed, voltage/frequency level can be adjusted in the beginning of application execution and must be the same for all processors. In the second scenario, the voltage/frequency level of a processor can be individually adjusted when a task execution starts, inputs of particular classes can be discarded without processing. In the third scenario, a processor voltage can be adjusted to the class of the input received. The fourth scenario aims at compensating for online changes of input class distribution in a system with the same capabilities as required for the third scenario.
tBRD-1 Selectively Controls Gene Activity in the Drosophila Testis and Interacts with Two New Members of the Bromodomain and Extra-Terminal (BET) Family

Multicellular organisms have evolved specialized mechanisms to control transcription in a spatial and temporal manner. Gene activation is tightly linked to histone acetylation on lysine residues that can be recognized by bromodomains. Previously, the testis-specifically expressed bromodomain protein tBRD-1 was identified in Drosophila. Expression of tBRD-1 is restricted to highly transcriptionally active primary spermatocytes. tBRD-1 is essential for male fertility and proposed to act as a co-factor of testis-specific TATA box binding protein-associated factors (tTAFs) for testis-specific transcription. Here, we performed microarray analyses to compare the transcriptomes of tbrd-1 mutant testes and wild-type testes. Our data confirmed that tBRD-1 controls gene activity in male germ cells. Additionally, comparing the transcriptomes of tbrd-1 and tTAF mutant testes revealed a subset of common target genes. We also characterized two new members of the bromodomain and extra-terminal (BET) family, tBRD-2 and tBRD-3. In contrast to other members of the BET family in animals, both possess only a single bromodomain, a characteristic feature of plant BET family members. Immunohistology techniques not only revealed that tBRD-2 and tBRD-3 partially co-localize with tBRD-1 and tTAFs in primary spermatocytes, but also that their proper subcellular distribution was impaired in tbrd-1 and tTAF mutant testes. Treating cultured male germ cells with inhibitors showed that localization of tBRD-2 and tBRD-3 depends on the acetylation status within primary spermatocytes. Yeast two-hybrid assays and co-immunoprecipitations using fly testes protein extracts demonstrated that tBRD-1 is able to form homodimers as well as heterodimers with tBRD-2, tBRD-3, and tTAFs. These data reveal for the first time the existence of single bromodomain BET proteins in animals, as well as evidence for a complex containing tBRDs and tTAFs that regulates transcription of a subset of genes with relevance for spermiogenesis.
Automatically Extracting and Representing Collocations for Language Generation

Collocational knowledge is necessary for language generation. The problem is that collocations come in a large variety of forms. They can involve two, three or more words, these words can be of different syntactic categories and they can be involved in more or less rigid ways. This leads to two main difficulties: collocational knowledge has to be acquired and it must be represented flexibly so that it can be used for language generation. We address both problems in this paper, focusing on the acquisition problem. We describe a program, Xtract, that automatically acquires a range of collocations from large textual corpora and we describe how they can be represented in a flexible lexicon using a unification based formalism.
Short review on the role of intracellular calcium in synaptic plasticity

Calcium (Ca) is ubiquitous second messenger in every living organism. Ca is inevitable, as the neurone functions in information reception, integration, processing, interpretation and subsequent activation of the peripheral nervous system to produce effect in the target organ. Normal intracellular calcium concentration ([Ca2+]i) ranges between 70 nM -150 nM [1]. The above mentioned functions connote plasticity. Synaptic plasticity is activity dependent alteration in synaptic strength, which mediates memory storage mechanism [2-4]. Donald Hebb (1949) postulated that excitatory synapses that link two cells could be strengthened if both cells were simultaneously activated [5]. This can be divided into long and short term plasticity. The long term plasticity is subdivided into long term potentiation (LTP) and depression (LTD). The short term plasticity is also subdivided into short term potentiation (STP) and depression (STD). I took a look at the various forms of synaptic plasticity and later on x-rayed the role of Ca in long-term, short-term plasticity and also the influence of neuronal Ca stores on calcium dynamic. Ca serves as a trigger for neurotransmitter release, sustains long term plasticity, which encodes long term memory and learning. The residual Ca mediates short term plasticity which likewise encodes short term memory. Thus calcium is essential in all forms of synaptic plasticity
An event-driven method to simulate Filippov systems with accurate computing of sliding motions

This article describes how to use smooth solvers for simulation of a class of piecewise smooth systems of ordinary differential equations, called Filippov systems, with discontinuous vector fields. In these systems constrained motion along a discontinuity surface (so-called sliding) is possible and requires special treatment numerically. The introduced algorithms are based on an extension to Filippov's method to stabilise the sliding flow together with accurate detection of the entrance and exit of sliding regions. The methods are implemented in a general way in MATLAB and sufficient details are given to enable users to modify the code to run on arbitrary examples. Here, the method is used to compute the dynamics of three example systems, a dry-friction oscillator, a relay feedback system and a model of an oil well drill-string.

TRANSPARENT TESTA8 Inhibits Seed Fatty Acid Accumulation by Targeting Several Seed Development Regulators in Arabidopsis1[C][W]

A maternal factor affects seed fatty acid biosynthesis and inhibits seed lipid accumulation by targeting seed development and down-regulating a group of genes critical to embryonic development. Fatty acids (FAs) and FA-derived complex lipids play important roles in plant growth and vegetative development and are a class of prominent metabolites stored in mature seeds. The factors and regulatory networks that control FA accumulation in plant seeds remain largely unknown. The role of TRANSPARENT TESTA8 (TT8) in the regulation of flavonoid biosynthesis and the formation of seed coat color is extensively studied; however, its function in affecting seed FA biosynthesis is poorly understood. In this article, we show that Arabidopsis (Arabidopsis thaliana) TT8 acts maternally to affect seed FA biosynthesis and inhibits seed FA accumulation by down-regulating a group of genes either critical to embryonic development or important in the FA biosynthesis pathway. Moreover, the tt8 mutation resulted in reduced deposition of protein in seeds during maturation. Posttranslational activation of a TT8-GLUCOCORTICOID RECEPTOR fusion protein and chromatin immunoprecipitation assays demonstrated that TT8 represses the activities of LEAFY COTYLEDON1, LEAFY COTYLEDON2, and FUSCA3, the critical transcriptional factors important for seed development, as well as CYTIDINEDIPHOSPHATE DIACYLGLYCEROL SYNTHASE2, which mediates glycerolipid biosynthesis. These results help us to understand the entire function of TT8 and increase our knowledge of the complicated networks regulating the formation of FA-derived complex lipids in plant seeds.
Manipulating polarization of electromagnetic waves through controllable metamaterial absorber

In this presentation, we demonstrate an approach to manipulate electromagnetic waves with different polarizations through a controllable metamaterial absorber. The metamaterial absorber designed at 3.3 GHz is proposed by properly integrating resonant unit cells with orthogonal polarization sensitivity onto a dielectric substrate and coupling the unit cells with microwave diodes. Simulation and measurement results show that through tuning the bias voltage on the diodes so as to change the coupling level between the resonant unit cells, the absorption rate is adjustable from nearly perfect absorption to nearly total reflection. Moreover, the proposed absorber can be controlled to selectively absorb one particularly polarized incident waves and reflect the orthogonally polarized ones with different bias voltage combinations. It is found in the measurement that the absorption rate remains over 89% with wide incident angles ranging from 0° – 50°. The proposed structure provides a novel way to realize electrically reconfigurable device for manipulating EM wave polarizations.
Compressive hematoma and deep arteriovenous malformation: Emergency endovascular occlusion via a venous approach with surgical evacuation of the hematoma

Compressive hematoma associated with deep arterio-venous malformation is a difficult surgery. Arterial presurgical embolization is often indicated but rarely effective. Endovascular occlusion via a venous approach is a technique that has recently been undertaken successfully to treat certain types of sub-pial vascular malformation. The venous endovascular approach has succeeded in a 20-year-old man of who presented with a compressive hematoma due to rupture of a deep arteriovenous malformation. By fully endovascular occlusion, the surgery consisted of surgical removal of the hematoma, with reduced cortical damage.
A Parallel Pruned Bit-Reversal Interleaver

A parallel algorithm and architecture for pruned bit-reversal interleaving (PBRI) are proposed. For a pruned interleaver of size N with mother interleaver size M = 2n ges N, the proposed algorithm interleaves any number x isin [0, N - 1] in at most n - 1 steps, as opposed to x steps using existing PBRI algorithms. A parallel architecture of the proposed algorithm employing simple logic gates and having a short critical path delay is presented. The proposed architecture is valuable in reducing (de-)interleaving latency in emerging wireless standards that employ PBRI channel (de-)interleaving in their PHY layer such as the 3GPP2 ultra mobile broadband standard.
Use of Doppler sonography for revealing hepatic artery stenosis in liver transplant recipients.

OBJECTIVE The goal of our study was to evaluate the use of duplex Doppler sonography for revealing hepatic artery stenosis (HAS) in patients who have undergone liver transplantation. MATERIALS AND METHODS Forty-six patients with spectral Doppler waveforms obtained from the hepatic artery and with subsequent arteriography were reviewed retrospectively. Arterial waveforms, resistive indexes (RIs), and systolic acceleration times (SATs) were evaluated by one reviewer who was unaware of the arteriographic findings. The mean interval between the two examinations was 2.8 days. Arteriograms that revealed a stenosis of greater than 50% were classified as abnormal. RESULTS Of the 46 patients, 21 (46%) had a significant stenosis. Patients who had HAS had significantly (p < .05) prolonged SATs (0.08 +/- 0.03 sec versus 0.06 +/- 0.02 sec) and reduced RIs (0.49 +/- 0.05 versus 0.66 +/- 0.05) compared with patients who did not have HAS. Optimal thresholds for HAS detection were RIs less than 0.55 and SATs greater than 0.08 sec. HAS was found in 14 of 15 patients who had both abnormal RIs and SATs. Of the remaining 31 patients, 12 had abnormal values for RI or SAT. Of these 12 patients, three had HAS. Thus, 19 patients had normal RIs and SATs; however, four of these patients were found to have an arterial stenosis. In our 46 patients, abnormal values for both RI and SAT were 67% sensitive and 96% specific for stenosis. When at least one abnormal value was found on Doppler imaging, sensitivity and specificity for stenosis were 81% and 60%, respectively. CONCLUSION Duplex Doppler imaging can noninvasively reveal HAS. Abnormal values for both RI and SAT proved to be a more accurate predictor of stenosis than either RI or SAT as independent parameters.
The spiral ganglion and Rosenthal's canal in beluga whales

With the increase of human activity and corresponding increase in anthropogenic sounds in marine waters of the Arctic, it is necessary to understand its effect on the hearing of marine wildlife. We have conducted a baseline study on the spiral ganglion and Rosenthal's canal of the cochlea in beluga whales (Delphinapterus leucas) as an initial assessment of auditory anatomy and health. We present morphometric data on the length of the cochlea, number of whorls, neuron densities along its length, Rosenthal's canal length, and cross‐sectional area, and show some histological results. In belugas, Rosenthal's canal is not a cylinder of equal cross‐sectional area, but its cross‐section is greatest near the apex of the basal whorl. We found systematic variation in the numbers of neurons along the length of the spiral ganglion, indicating that neurons are not dispersed evenly in Rosenthal's canal. These results provide data on functionally important structural parameters of the beluga ear. We observed no signs of acoustic trauma in our sample of beluga whales. J.

Conformally Invariant Operators, Differential Forms, Cohomology and a Generalisation of Q-Curvature

On conformal manifolds of even dimension n ≥ 4 we construct a family of new conformally invariant differential complexes, each containing one coboundary operator of order greater than 1. Each bundle in each of these complexes appears either in the de Rham complex or in its dual (which is a different complex in the non-orientable case). Each of the new complexes is elliptic in case the conformal structure has Riemannian signature. We also construct gauge companion operators which (for differential forms of order k ≤ n/2) complete the exterior derivative to a conformally invariant and (in the case of Riemannian signature) elliptically coercive system. These (operator, gauge) pairs are used to define finite dimensional conformally stable form subspaces which are are candidates for spaces of conformal harmonics. This generalizes the n/2-form and 0-form cases, in which the harmonics are given by conformally invariant systems. These constructions are based on a family of operators on closed forms which generalize in a natural way Branson's Q-curvature. We give a universal construction of these new operators and show that they yield new conformally invariant global pairings between differential form bundles. Finally we give a geometric construction of a family of conformally invariant differential operators between density-valued differential form bundles and develop their properties (including their ellipticity type in the case of definite conformal signature). The construction is based on the ambient metric of Fefferman and Graham, and its relationship to the tractor bundles for the Cartan normal conformal connection. For each form order, our derivation yields an operator of every even order in odd dimensions, and even order operators up to order n in even dimension n. In the case of unweighted (or true) forms as domain, these operators are the natural form analogues of the critical order conformal Laplacian of Graham et al., and are key ingredients in the new differential complexes mentioned above.
Pyrazolidine-3,5-dione angiotensin-II receptor antagonists.

The crystal structures of three angiotensin-II receptor antagonists involving different spacer groups (CO, CONH and NHCO) between the aryl rings are presented, namely 2-[4-[(3-butyl-1,4-dioxo-2,3-diazaspiro[4.4]non-2-yl)methyl]benzoyl]benzoic acid, C(26)H(28)N(2)O(5), (I), 2-[4-[(3-butyl-1,4-dioxo-2,3-diazaspiro[4.4]non-2-yl)methyl]benzamido]benzoic acid, C(26)H(29)N(3)O(5), (II), and 2-[4-[(3-butyl-1,4-dioxo-2,3-diazaspiro[4.4]non-2-yl)methyl]anilinocarbonyl]benzoic acid monohydrate, C(26)H(29)N(3)O(5) x H(2)O, (III). The aryl rings of (II) are almost coplanar, in contrast with compounds (I) and (III). The conformation of (II) is induced by an intramolecular N-H.O hydrogen bond between the amide and carboxylic acid groups.
Ieee Computer Graphics and Applications Cooking up an Interactive Olfactory Game Display

75 I t's long been possible to give users outside an actual environment that environment's visual and auditory information and thus contribute to establishing presence. However, we've yet to establish much presence when users require olfactory information—such as in environments focused on foods, flowers, perfumes, or, in some cases, more offensive smells. Several general research projects have focused on presenting olfactory information. For example, some researchers have used olfactometers to give test subjects an olfactory stimulus and thereby investigate human olfactory characteristics, olfactory thresholds, and electroencephalogram (EEG) reactions. However, the equipment is too large and complicated for VR people to use easily. Also, while a simple aroma dif-fuser is commercially available for aromatherapy, you can't quickly change the smells it emits. A few years ago, a PC-controlled scent diffuser appeared, but it can't blend scents, so it offers a quite limited range of smells. Recently, several VR researchers have become interested in olfaction and olfactory displays that present smells in virtual environments (VEs). 1 For example, researchers have studied a device to present different smells according to the stock market's state; an olfacto-ry display for localizing a smell's source in a VE; and " spotscents " produced using air cannons. Although such olfactory displays are useful in certain situations, they present a limited range of smells. We've developed an olfactory display capable of real-time scent blending. 2 Because our display can blend multiple odor components into numerous " recipes, " it offers a significant variety of smells. Moreover, users can change the recipes continuously in real time. We've used this olfactory display to add scents to both movies and anima-tions to study how olfaction contributes to presence. 3 The results of our follow-on questionnaire revealed that the scene with the appropriate smell attracted users' attention and, moreover, that contrasting a pleasant smell with an offensive smell increased users' attention. Here, we describe our interactive olfactory display. One of our development goals is to confirm the assumption that users' interactions with the system increases presence. Thus, we used our interactive olfactory display to develop a cooking game in collaboration with electronic engineers and artists. Interactive olfactory displays To realize olfaction in VEs, we must consider several aspects of olfactory displays: ■ the number and range of available smells; ■ the ability to adjust smell concentration to cover the range of human smell perception; ■ the speed of odor variation, both in …
Evaluation of a Practical Visual MRI Rating Scale of Brain White Matter Hyperintensities for Clinicians Based on Largest Lesion Size Regardless of Location

BACKGROUND AND PURPOSE: Age-related white matter hyperintensities have prognostic implications, but no accepted clinical standard exists for their assessment. We propose a simple objective visual rating system by using 3T brain MR imaging. MATERIALS AND METHODS: MR imaging from 559 participants was processed by using an automated method to determine WMH volumes and evaluated with a new visual rating scale based on the single largest WMH lesion diameter regardless of location. The reproducibility of the visual system was assessed. The association of WMH visual scores and automated volumes was then compared with cognitive scores from the Montreal Cognitive Assessment, which was available for 510 participants. RESULTS: Inter-reader reproducibility was good for subsamples with both high (n = 52) and low (n = 40) prevalence of large automated WMH volumes (agreement of 67% and 87.5%, κ = 0.71 and 0.76, respectively). Correlation between increased WMH and cognitive deficit measurements was equal for our visual ratings and automated volumes (Spearman ρ = 0.118 and 0.109; P values = 0.008 and 0.014, respectively). The visual scale retained a significant association with MoCA score after adjusting for age, sex, and education (standardized β = −0.087, P = .042). CONCLUSIONS: We propose a simple visual WMH scoring system suitable for use as a baseline evaluation in clinical practice.
Queued Testing of Transition Systems with Inputs and Outputs

The paper studies testing based on input/output transition systems, also known as input/output automata. It is assumed that a tester can never prevent a system under test from producing outputs, while the system does not block inputs from the tester either. Thus, input from the tester and output from the system may occur simultaneously and should be queued in finite buffers between the tester and system. A framework for a so-called queued-quiescence testing is developed, based on the idea that the tester should consist of two test processes, one process is applying inputs via a queue to a system under test and another one is reading outputs from a queue until it detects no more outputs from the system, i.e., the tester detects quiescence in the system. The testing framework is then generalized with a so-called queued-suspension testing by considering a tester that has several pairs of input and output processes. It is demonstrated that such a tester can check finer implementation relations than a queued-quiescence tester. Procedures for test derivation are proposed for a given fault model comprising possible implementations.
