Meta-Concept Features for Text-Illustration

Cross-media retrieval is a problem of high interest that is at the frontier between computer vision and natural language processing. e state-of-the-art in the domain consists of learning a common space with regard to some constraints of correlation or similarity from two textual and visual modalities that are processed in parallel and possibly jointly. is paper proposes a dierent approach that considers the cross-modal problem as a supervised mapping of visual modalities to textual ones. Each modality is thus seen as a particular projection of an abstract meta-concept, each of its dimension subsuming several semantic concepts (“meta” aspect) but may not correspond to an actual one (“abstract” aspect). In practice, the textual modality is used to generate a multi-label representation, further used to map the visual modality through a simple shallow neural network. While being quite easy to implement, the experiments show that our approach signicantly outperforms the state-of-theart on Flickr-8K and Flickr-30K datasets for the text-illustration task. e source code is available at hp://perso.ecp. fr/∼tamaazouy/.
ℒ1 adaptive anti-slug control

In many multiphase pipeline-riser systems, anti-slug control is necessary to ensure steady and optimal operation. In this paper, we propose using an ℒ1 adaptive controller as an augmentation to standard PI control to stabilize the desired non-slugging flow regime. The ℒ1 adaptive controller is designed based on a model identified from an experimental closed-loop step test. The proposed design involves fewer tuning parameters compared to other adaptive control methods and it does not need any observer. We have tested the controller by simulations in both MATLAB and OLGA, and by experiments in a small-scale laboratory. The results show that the proposed solution can stabilize the process outside the stability region of the traditional PI controller.
Liquid-ChromatographicQuantificationCompared with Gas-Chromatographic-Mass-SpectrometncDeterminationof Verapamil and Norverapamilin Plasma

A high-performance liquid chromatographic (H PLC) method for determining verapamil and norverapamil in plasma is presented and compared with gas chromatography/mass spectrometry (GC-MS). The plasma samples were extracted at alkaline pH with hexane containing 2-butanol (20 mL/L) and then back-extracted into phosphate buffer (0.1 mol/L, pH 3.0). For chromatography we used a reversed-phase column (Supelcosil LC-1 8 DB) with a mobile phase of the phosphate buffer and acetonitrile (70/30 by vol). Fluorescence detection was used (excitation at 203 nm, emission at 320 nm). Overall analytical recovery was 85%. Standard curves were linear from I to 1000 g/L. The detection limit was 1 1zg/L. The assays are accurate and precise. We found no interferences by those substances tested. Results by HPLC and GC-MS agreed well (r = 0.99) for both verapamil and norverapamil determinations.
Simulaçao das Trajetórias de Poluentes em Eventos Naturais e Antropogênicos

Diversas evidencias suportam a ideia de que o Homo sapiens tem se transformado em uma forca geologica, capaz de introduzir mudancas que afetam nao apenas sua propria vida, mas a vida de todas as especies sobre a Terra e sobre o equilibrio dos processos quimicos e biologicos. Atualmente alguns eventos antropogenicos, como acidentes em fabricas e plantas industriais de geracao de energia, especialmente a nuclear, podem liberar grandes quantidades de poluentes e afetar a vida sobre a Terra em forma semelhante a processos naturais, como erupcoes vulcânicas. Neste trabalho e apresentado o modelo de trajetorias HYSPLIT (Hybrid Singled-Particle Lagrangian Integrated Trajectory), de facil implementacao, para simular as trajetorias de massas de ar. Como estudo de caso, sao discutidos um evento natural, a erupcao do vulcao Puyehue (Chile) e um incendio na regiao portuaria de Guaruja (SP, Brasil). A erupcao do vulcao se iniciou no dia 04 de junho de 2011 e as cinzas atingiram inicialmente a regiao de Bariloche e Villa La Angostura (Argentina) e posteriormente o norte da Patagonia, chegando a Buenos Aires (Argentina) e posteriormente a Uruguai, Paraguai, Bolivia e o sul de Brasil (Rio Grande do Sul e Santa Catarina). O incendio no Guaruja aconteceu durante 37 horas e se iniciou em um terminal de cargas do porto no dia 14 de janeiro de 2016. Os gases toxicos afetaram a area do acidente (Distrito de Vicente de Carvalho na cidade de Guaruja, SP), se espalhando por Guaruja e chegando a Santos e Cubatao. O modelo HYSPLIT permitiu reproduzir a trajetoria das massas de ar em um bom acordo com os dados disponiveis sobre ambos os eventos. O trabalho mostra que o programa, que pode ser utilizado online, fornece resultados satisfatorios, compativeis com imagens de satelite e informacoes de agencias meteorologicas e de qualidade do ar, tanto para desastres naturais, como erupcoes vulcânicas e queimadas em florestas, quanto para acidentes industriais, como aqueles em usinas nucleares e incendios em fabricas
Effect of drying treatments on the contents of lutein and zeaxanthin in orange- and yellow-cultivars of marigold flower and its application for lutein ester encapsulation

Marigold (Tagetes erecta L.) flower is a potential source of lutein and zeaxanthin. The drying treatment of marigold flower is necessary during the industrial process for the preparation of these carotenoids. However, drying treatments with high temperature led the carotenoids undergo the isomerization reaction. Therefore, the aims of this study are to examine the effect of several drying treatments on lutein and zeaxantin contents, and to characterize a versatility of encapsulated lutein ester powder. Separations of the pigments were performed by highperformance liquid chromatography (HPLC) equipped with photodiode array detector on a C30 column. All-trans isomer of lutein was identified as the major carotenoid of two different marigold cultivars, i.e. Mega Gold (MG) and Mega Orange (MO). The contents of all-trans isomers of lutein and zeaxanthin were 8.95 − 14.55 mg/g dry weight (dw) in MO and 2.56 - 3.73 mg/g dw in MG. The best drying treatment to maintain carotenoid content was freeze drying, while the treatment with oven at 100°C decreased in carotenoids content up to 38%. The encapsulated lutein esters by spray drying and freeze drying showed microparticle size with the different morphological shapes. The encapsulated powders by spray drying produced uniform particles with sperical shape and smooth as well as concave surfaces, while the broken glass of encapsulated powders was obtained by freeze drying. MO cultivar of marigold appears to be a potential source of lutein and zeaxanthin. Encapsulation process may increase in the solubility of carotenoids and widen its application in food or nutraceutical products.
A cytoplasmic factor, calpastatin and ATP together reverse run‐down of Ca2+ channel activity in guinea‐pig heart

1 The cytoplasmic extract of bovine heart was separated into four fractions by gel filtration: H (molecular mass > 300 kDa), P (250‐300 kDa), L1 (180‐250 kDa) and L2 (< 180 kDa). The effects of these fractions on the run‐down of L‐type Ca2+ channel activity were investigated in guinea‐pig ventricular myocytes. 2 After run‐down induced by inside‐out patch formation, Ca2+ channel activity was restored by P or H (+ 3 mM ATP) to 7·5 and 5·8 % of that in the cell‐attached mode, respectively, but to as high as 86 % by P + H + ATP. 3 The reversal of run‐down brought about by the P fraction was mimicked by calpastatin. 4 The restorative effect of calpastatin + ATP showed a biphasic time course: 38 % in the early transient phase and 11 % in the late phase. However, calpastatin + H + ATP showed a sustained effect: 66 % in the early transient phase, and 87 % in the late phase. 5 The effective component of the H fraction showed a protein‐like nature: heat and trypsin sensitivity. 6 The activities of cAMP‐dependent protein kinase, casein kinase I, casein kinase II, protein tyrosine kinase, protein serine/threonine or tyrosine phosphatases were measured. However, these kinases and phosphatases were not confirmed as the effective component of cytoplasm or the H fraction. 7 Run‐down was not prevented by 2 μM phalloidin or 2 μM paclitexal, suggesting that neither actin filaments nor microtubules are directly involved in the run‐down. 8 Our results support the view that the basal activity of the Ca2+ channel is maintained by at least three factors: a protein‐like factor in the H fraction, calpastatin, and ATP.
Estimation of dry docking duration using a numerical ant colony decision tree

Classification and regression tree (CART) has been widely used in data mining to solve classification and prediction problems. In this paper, we propose a novel numerical ant-colony decision tree (nACDT) algorithm that combines CART with ant-colony optimisation (ACO). The combination works not only in inducing decision trees but also in incorporating the discretisation of attributes during the process to cope with continuous attributes. The proposed algorithm is used to estimate the duration of ship maintenance, with the aim of improving service quality and competitive advantage in the shipyard industry. The results show that the predictive accuracy of the proposed algorithm is statistically significantly higher than the accuracy of CART, which is the most well-known conventional decision tree algorithm.
Chapter 10 Sedimentary geochemistry used to infer the provenance of Permian–Triassic marine sandstones related to the SE Gondwana active continental margin, South Island, New Zealand

Abstract Major, trace and rare earth element data for sandstones and conglomerates from the Mid-Permian–Mid-Triassic Maitai Group are compared with other tectonostratigraphic units, using discrimination diagrams and comparisons with potential source terranes. Maitai Group sandstones reveal a mainly ophiolitic–oceanic-arc source during the Mid-Permian, followed by a mixed continental margin-arc–terrigenous source during the Late Permian. Latest Permian–Early Triassic sandstones mainly came from little-evolved continental margin-arc extrusives, tending to more evolved (but variable) during the Triassic. Source volcanism of the Murihiku Terrane sandstones was magmatically evolved relative to the Maitai Group generally (except during the Late Triassic). The Maitai Group and Murihiku Terrane are restored as proximal and more distal parts, respectively, of the SE Gondwana forearc basin. The localized Willsher Group shows some Maitai Group affinities. Sandstones in two melanges that formed in an outer forearc–subduction trench setting mainly indicate a mixed terrigenous–continental margin-arc source, similar to the Late Permian Maitai Group. The Caples Terrane, a Triassic accretionary prism, received detritus from little-evolved, to evolved continental margin-arc volcanics and terrigenous sources. Much of the arc-related material in all units is compatible with derivation from the latest Permian–Triassic Median Batholith, or a lateral equivalent along the SE Gondwana active margin.
FPGA Implementation of Token-Based Clam AV Regex Virus Signatures with Early Detection

This paper describes hardware architecture for high speed regex pattern matching with ClamAV virus database. The proposed method is incorporated with a new technique namely early detection in matching the regex patterns. With the information reduction approach, instead of viewing the pattern matching as byte sequences, the input byte stream is transformed into a token stream. The processing architecture will then process the token stream with bit-split string matching method to determine if any virus signatures can be found. Furthermore, this paper proposes a novel reconfigurable clock divider model to avoid synchronization problems during page-enabled parallel processing. The detection engine is memory-based and therefore the FPGA need not be reconfigured to support dynamic updates. The proposed approach can provide worst-case performance guarantee also for variable rate pattern match and efficient in terms of power with gated latch control circuit.
Retrospective Interference Alignment for the $K$ -User $M\times N$ MIMO Interference Channel

In this paper, we consider a K-user M × N MIMO interference channel, with outdated channel state information at the transmitters (CSIT). Based on the technique introduced by Cadambe and Jafar, for the IC with perfect and up-to-date CSIT, we propose and analyze a scheme that guarantees interference alignment with outdated CSIT. The interference is aligned by the transmitters, and removed by the receivers using zero-forcing by Cadambe and Jafar. However, this is not feasible for the IC with outdated CSIT, since there is no up-to-date CSIT to compute the interference alignment precoders. To overcome this limitation, we propose that the interference should be aligned by the receivers instead. With this approach, the interference caused by a transmitter spans the same subspace at all receivers, i.e., the interference at receiver k ≠ m may be obtained through a linear map from the interference at receiver m. Therefore, one interference retransmission per transmitter is enough to cancel all the interference. This reduces the overhead required for interference removal from K(K -1) to K interference terms.
Using multiscale texture and density features for near-term breast cancer risk analysis.

PURPOSE To help improve efficacy of screening mammography by eventually establishing a new optimal personalized screening paradigm, the authors investigated the potential of using the quantitative multiscale texture and density feature analysis of digital mammograms to predict near-term breast cancer risk. METHODS The authors' dataset includes digital mammograms acquired from 340 women. Among them, 141 were positive and 199 were negative/benign cases. The negative digital mammograms acquired from the "prior" screening examinations were used in the study. Based on the intensity value distributions, five subregions at different scales were extracted from each mammogram. Five groups of features, including density and texture features, were developed and calculated on every one of the subregions. Sequential forward floating selection was used to search for the effective combinations. Using the selected features, a support vector machine (SVM) was optimized using a tenfold validation method to predict the risk of each woman having image-detectable cancer in the next sequential mammography screening. The area under the receiver operating characteristic curve (AUC) was used as the performance assessment index. RESULTS From a total number of 765 features computed from multiscale subregions, an optimal feature set of 12 features was selected. Applying this feature set, a SVM classifier yielded performance of AUC = 0.729 ± 0.021. The positive predictive value was 0.657 (92 of 140) and the negative predictive value was 0.755 (151 of 200). CONCLUSIONS The study results demonstrated a moderately high positive association between risk prediction scores generated by the quantitative multiscale mammographic image feature analysis and the actual risk of a woman having an image-detectable breast cancer in the next subsequent examinations.
The Inhibition of Glutamate Release by Metabotropic Glutamate Receptor 7 Affects Both [Ca2+] c and cAMP

Metabotropic glutamate receptors (mGluRs) from group III reduce glutamate release. Because these receptors reduce cAMP levels, we explored whether this signaling pathway contributes to release inhibition caused by mGluRs with low affinity forl-2-amino-4-phosphonobutyrate (l-AP4). In biochemical experiments with the population of cerebrocortical nerve terminals we find that l-AP4 (1 mm) inhibited the Ca2+-dependent-evoked release of glutamate by 25%. This inhibitory effect was largely prevented by the pertussis toxin but was insensitive to inhibitors of protein kinase C bisindolylmaleimide and protein kinase A H-89. Furthermore, this inhibition was associated with reduction in N-type Ca2+ channel activity in the absence of any detectable change in cAMP levels. In the presence of forskolin, however,l-AP4 decreased the levels of cAMP. The activation of this additional signaling pathway was very efficient in counteracting the facilitation of glutamate release induced either by forskolin or the β-adrenergic receptor agonist isoproterenol. Imaging experiments to measure Ca2+ dynamics in single nerve terminals showed thatl-AP4 strongly reduced the Ca2+ response in 28% of the nerve terminals. Moreover, immunochemical experiments showed that 25–35% of the nerve terminals that were immunopositive to synaptophysin were also immunoreactive to the low affinityl-AP4-sensitive mGluR7. Then, mGluR7 mediates the inhibition of glutamate release caused by 1 mm l-AP4, primarily by a strong inhibition of Ca2+channels, although high cAMP uncovers the receptor ability to decrease cAMP.
Establishing the Service Potential of Secondary Level Low Vision Clinics

Purpose. To determine the proportion of people with low vision who can be adequately managed at a secondary level low vision clinic where only low to moderate magnification low vision devices (LVDs) and basic rehabilitation services are provided. Methods. A retrospective study of clinical records of participants who attended low vision rehabilitation services (Vision Australia) for the first time between 2000 and 2002 was conducted. Information regarding main cause of vision loss, goals of vision rehabilitation, types of LVDs purchased, and type of services received was examined. Results. Of the 192 participants studied, 65% were female and the mean age was 76 years (range, 19 to 100 years). Most participants had mild (35%) to moderate (49%) vision impairment. Seventy percent (134) of participants purchased some type of LVDs. Near adds of low magnification (1 to 2×) were the most common aid preferred by participants (n = 54) followed by handheld magnifiers of moderate magnification (2.5 to 5×; (n = 52). Only 10 of the 134 LVDs (8%) purchased were of high magnification (>5×). In addition, only 46 of the 192 participants (24%) attended tertiary level rehabilitation with orientation and mobility (O&M) instructors and/or occupational therapists. Along with the six participants who required high magnification LVDs but no O&M or OT services, in total, 27% (52/192) required tertiary level low vision care. Conclusions. A secondary level low vision clinic is likely to meet the needs of >70% of people with vision impairment. It would play an important role in vision rehabilitation especially in countries where a wide range of services are available.
In pursuit of Irving and Scholander: a review of oxygen store management in seals and penguins

Summary Since the introduction of the aerobic dive limit (ADL) 30 years ago, the concept that most dives of marine mammals and sea birds are aerobic in nature has dominated the interpretation of their diving behavior and foraging ecology. Although there have been many measurements of body oxygen stores, there have been few investigations of the actual depletion of those stores during dives. Yet, it is the pattern, rate and magnitude of depletion of O2 stores that underlie the ADL. Therefore, in order to assess strategies of O2 store management, we review (a) the magnitude of O2 stores, (b) past studies of O2 store depletion and (c) our recent investigations of O2 store utilization during sleep apnea and dives of elephant seals (Mirounga angustirostris) and during dives of emperor penguins (Aptenodytes forsteri). We conclude with the implications of these findings for (a) the physiological responses underlying O2 store utilization, (b) the physiological basis of the ADL and (c) the value of extreme hypoxemic tolerance and the significance of the avoidance of re-perfusion injury in these animals.
UAV navigation in GPS-denied environment using particle filtered RVL

Unmanned aerial vehicles have become widespread in today’s world and are used for applications ranging from real estate marketing and bridge inspection to defense and military applications. These applications have in common some form of autonomous navigation that requires a good localization capability at all time. Most UAV are using a combination of global navigation satellite systems (GNSS) and inertial measurement unit (IMU) to perform this task. Unfortunately, GNSS are subject to signal unavailability and all sorts of interference impeding on the ability of the UAV to self-localize. In this paper, we propose a new algorithm to perform localization in GNSS-denied environments by using a relative visual localization technique. We developed a new measure based on the use of local feature points extracted with ORB to estimate the likelihood of a previously captured image to have been taken in a position close to the current UAV location. The measure is embedded in a particle filter in which IMU data is used in order to reduce the number of images we need to analyze to perform localization. The resulting method have shown significant improvement in both accuracy and execution time in comparison to previous approaches.
[The links between learning load and well-being of high school seniors].

OBJECTIVE To evaluate the links between learning overload and psychoemotional well-being of 12th grade students. MATERIAL AND METHODS In April 2006, an anonymous survey of 184 high school seniors was conducted in six secondary schools and one gymnasium of Kaunas. RESULTS The total learning load of students was too high and made up 54.79+/-0.98 hours on average. The learning load of 61.4% of children was too high; girls mentioned this problem two times more often than boys did. Students suffered from psychoemotional problems: about half of them felt stress at school; every fifth fell asleep with difficulties. Students whose total learning load was too high (more than 48 hours per week) felt stress, tiredness, stomach or abdominal, head or back pains, vertigo or weakness significantly more often in comparison with those who had normal learning load. CONCLUSIONS The total learning load of the majority of investigated high school seniors was too high. The psychoemotional well-being of 12th graders was unsatisfactory; girls complained about worse well-being than boys more frequently, they used medicine more frequently in comparison to the students whose learning load was normal.
Energy consumption and GDP with the role of trade in South Asia

This study investigates the dynamic linkages between energy consumption, GDP and trade by using panel co-integration technique and panel Granger causality test, over the period 1980-2009 for South Asian economies. The empirical outcomes show that feedback relationship holds between energy consumption and GDP and between energy consumption and exports (trade) in the short run. There also exists unidirectional causal relation running from energy to imports (trade) in the short run while feedback relationship between these in the long run. Moreover, there is evidence of unidirectional causal relation running from export (trade) to energy in the long run. The main implications are that any shortage of energy supply will lessen the imports and exports of the countries directly and impede GDP growth indirectly.
Slew-Rate and Efficiency Trade-off in Slow Envelope Tracking Power Amplifiers

Abstract This paper presents a study on the trade-off between the envelope's slew-rate and the drain efficiency when slower envelopes are considered to dynamically supply the power amplifier (PA). This paper discusses a method to limit the slew-rate (and consequently the bandwidth) of the signal's envelope. Moreover, since the envelope tracking (ET) technique using a slower version of the original envelope introduces nonlinear distortion, slow envelope dependent predistortion has to be also incorporated in the design of ET PAs. Experimental results showed that it is possible to find a compromise between the bandwidth and slew-rate reduction (necessary to cope with the specific envelope amplifier requirements) and the amount of drain efficiency degradation suffered due to the use of a slower version of the original envelope.
