UpStream

UpStream is a framework for load management over data streams with update semantics. It provides a novel storage manager architecture that can be plugged into data stream processing engines for serving streaming applications that require low-staleness results over real-time continuous queries. We propose to demonstrate the key aspects of the UpStream architecture as well as its performance using two different application scenarios: One that models a continuously updating financial market dashboard, and another one that is based on an intelligent transportation system for monitoring moving vehicles on a road traffic network. The demonstration will illustrate how UpStream can provide low-staleness query results for these applications under highly overloaded situations, by using a number of update scheduling and storage management techniques. This will be done through a number of interactive visual monitoring tools for the application interface as well as for monitoring the run-time operation of the UpStream system itself.
Unionid mussels as stable isotope baseline indicators for long-lived secondary consumers in pelagic food web comparisons

Stable isotope signatures of filter-feeding freshwater mussels have been established as a convenient baseline measure at the primary consumer level for comparisons of pelagic food webs. We studied this idea with four unionid mussel species Anodonta sp. (A. anatina), Pseudanodonta complanata, Uniopictorum and U. tumidus in four Finnish lakes. δ 15 N and δ 13 C signatures of mussels were compared with surface sediment and summer averages of their potential food sources and planktonic herbivores. Isotope compositions of Anodonta, Pseudanodonta and Unio differed significantly between lakes but were roughly similar within lakes, except in the smallest study lake. There was considerable deviation in the δ 13 C of mussels relative to that of particulate organic matter (POM) in water or sediment, suggesting selective use of food sources. The δ 13 C of POM also showed considerable temporal variation. Enrichment in δ 15 N mussels over that of POM was less than expected, but the mussel signatures matched closely with those of herbivorous Daphnia. We suggest that unionid mussels can provide a reasonable baseline estimate for pelagic food web comparisons with much less sampling effort than other suggested primary consumers.
LSDDN: A Lightweight End-to-End Network for Surface Defect Detection

Surface defect detection is a key method to control product quality in industry. Deep learning based surface defect detection algorithm plays a crucial role in improving industrial production efficiency. A large number of existing CNN models aim at building deeper and larger structures, thus deep network models are difficult to be applied in the industrial field because of the requirement of speed in industry. This paper proposes a lightweight end-to-end surface defect detection network (LSDDN) to overcome this problem. LSDDN significantly reduces the number of parameters and improves the detection speed while maintaining a high accuracy. We validate our model on the DAGM2007 dataset with an average classification accuracy of 97.23%.
Les jonctions serrées : Plate-forme de régulation de la prolifération et de la polarité cellulaires

Les jonctions serrees scellent les cellules epitheliales et endotheliales entre elles. Elles ont ete longtemps considerees comme de simples barrieres separant les deux compartiments membranaires apical et basolateral, dont la composition en proteines et lipides est differente. De recentes etudes montrent que diverses proteines impliquees dans la transduction de signaux et le trafic membranaire sont associees aux jonctions serrees. Ces dernieres servent de lieu d’integration et de transmission de signaux necessaires a la regulation de leur assemblage et a la polarisation cellulaire, mais aussi a la modulation de l’expression des genes requise pour la proliferation et la differenciation cellulaires.
Sequential extraction and speciation of Ba, Cu, Ni, Pb and Zn in soil contaminated with automotive industry waste

Abstract Sequential extraction or fractionation of heavy metals in the solid phase and their speciation in soil solution are important tools for assessing changes resulting from land use and/or pollution. The distribution of the various forms of Ba, Cu, Ni, Pb and Zn was evaluated in soil samples taken from a polluted area, and the speciation of cations and anions in a soil solution contaminated with automotive industry waste. We evaluated the sequential extraction and speciation of Ba, Cu, Ni, Pb and Zn in a Leptosol associated with a Cambisol and contaminated with automotive industry waste. Soil samples were collected at 0-0.2 m (a mix of soil and waste); 0.2-0.4 m (waste only), and 0.4-0.6 m (soil only) both in the polluted area and in two contiguous unpolluted areas: a sugarcane plantation and a forest fragment. Total concentrations of metals in the polluted area were above limits for intervention established by European Community regulations. Cu was mostly distributed in the residual and in the oxide-bonded fractions, except for the waste-only sample, in which the carbonate-bonded fraction was significant. Zn was concentrated in the residual and carbonate-bonded fractions, while Ba, Ni and Pb predominated in the residual fraction of the contaminated samples. Metals in the soil solution were predominantly in the hydroxyl forms, except for Ba, which was mostly in the ionic form (Ba2+).
Prior Stroke in PFO Patients Is Associated With Both PFO-Related and -Unrelated Factors

Background and Purpose: To identify factors associated with prior stroke at presentation in patients with cryptogenic stroke (CS) and patent foramen ovale (PFO). Methods: We studied cross-sectional data from the International PFO Consortium Study (NCT00859885). Patients with first-ever stroke and those with prior stroke at baseline were analyzed for an association with PFO-related (right-to-left shunt at rest, atrial septal aneurysm, deep venous thrombosis, pulmonary embolism, and Valsalva maneuver) and PFO-unrelated factors (age, gender, BMI, hypertension, diabetes mellitus, hypercholesterolemia, smoking, migraine, coronary artery disease, aortic plaque). A multivariable analysis was used to adjust effect estimation for confounding, e.g., owing to the age-dependent definition of study groups in this cross-sectional study design. Results: We identified 635 patients with first-ever and 53 patients with prior stroke. Age, BMI, hypertension, diabetes mellitus, hypercholesterolemia, coronary artery disease, and right-to-left shunt (RLS) at rest were significantly associated with prior stroke. Using a pre-specified multivariable logistic regression model, age (Odds Ratio 1.06), BMI (OR 1.06), hypercholesterolemia (OR 1.90) and RLS at rest (OR 1.88) were strongly associated with prior stroke.Based on these factors, we developed a nomogram to illustrate the strength of the relation of individual factors to prior stroke. Conclusion: In patients with CS and PFO, the likelihood of prior stroke is associated with both, PFO-related and PFO-unrelated factors.
Comparative microsporangium development in male‐fertile and male‐sterile flowers of Consolea (Cactaceae): When and how does pollen abortion occur

Anther development, microsporogenesis, and microgametogenesis were studied using both light and TEM microscopy in the six accessible subdioecious/cryptically dioecious species of Consolea (Cactaceae). Anther wall development, microsporogenesis, and microgametogenesis are uniform in staminate flowers of all six species, and are typical for Cactaceae. Breakdown of microsporogenesis in male‐sterile anthers occurs early, at the onset of meiosis, and results in anthers bearing no pollen grains. The abortive process follows a common pattern in all investigated species. The tapetum is the first layer to deviate from normal male‐fertile anther development. Tapetal cells in male‐sterile anthers elongate at an early stage and have abundant rER with atypical configurations. Ultimately, the tapetum becomes hypertrophied and non‐functional. Male‐sterility in pistillate flowers appears to be directly related to these anomalies. In addition, other anther layers and tissues are affected, and normal patterns of programmed cell death (PCD) are disrupted. The relationship between these patterns and the pattern of PCD in normal male‐fertile anthers is discussed. We hypothesize a single origin for the cryptically dioecious/subdioecious breeding system of Consolea based on the uniformity of the anther's abortive processes in pistillate flowers.
Preliminary Immunomodulatory Activities of the Aqueous Extract of Terminalia chebula.

ABSTRACT Terminalia chebula. (Gaertn.) Retz. (Combretaceae), a plant widely used in the traditional medicinal systems of India, has been reported to possess antibacterial, laxative, antioxidant, and diuretic activities. In the current study, the aqueous fruit extract of Terminalia chebula. has been investigated for its effect on cell-mediated and humoral components of the immune system in mice. Administration of Terminalia chebula. extract produced an increase in humoral antibody (HA) titer and delayed-type hypersensitivity (DTH) in mice. It was concluded that the Terminalia chebula. extract is a promising drug with immunostimulant properties.
Biological Control of Soilborne Diseases on Tomato, Potato and Black Pepper by Selected PGPR in the Greenhouse and Field in Vietnam

Bacterial wilt, Fusarium wilt and Foot rot caused by Ralstonia solanacearum, Fusarium oxysporum, and Phytophthora capsici respectively, continue to be severe problems to tomato, potato and black pepper growers in Vietnam. Three bio-products, Bacillus vallismortis EXTN-1 (EXTN-1), Bacillus sp. and Paenibacillus sp. (ESSC) and Bacillus substilis (MFMF) were examined in greenhouse bioassay for the ability to reduce bacterial wilt, fusarium wilt and foot rot disease severity. While these bio-products significantly reduced disease severities, EXTN-1 was the most effective, providing a mean level of disease reduction 80.0 to 90.0% against bacterial wilt, fusarium wilt and foot rot diseases under greenhouse conditions. ESSC and MFMF also significantly reduced fusarium wilt, bacterial wilt and foot rot severity under greenhouse conditions. Bio-product, EXTN-1 with the greatest efficacy under greenhouse condition was tested for the ability to reduce bacterial wilt, fusarium wilt and foot rot under field condition at Song Phuong and Thuong Tin locations in Ha Tay province, Vietnam. Under field condition, EXTN-1 provided a mean level of disease reduction more than 45.0% against all three diseases compared to water treated control. Besides, EXTN-1 treatment increased the yield in tomato fruits 17.3% than water treated control plants.
Body Weight, Intestinal Morphometry and Cell Proliferation of Broiler Chickens Submitted to Cyclic Heat Stress

To investigate the effects of heat stress on body weight, intestinal length, mucous area, crypt’s depth, villus height and percentage of cells in proliferation activity in male broiler chickens, one hundred birds of Avian Farms strain were housed in cages and divided into two groups, the reared under heat stress and in thermoneutrality. The group reared under heat stress was submitted daily, from 12-13 h, to 38 C from first o to 27th day old and 40 C from 28 to 42nd day. The group reared in thermoneutrality was maintained for 24 o h in comfort temperature. The body weight of ten birds of each group was obtained weekly from the first until 42nd day old. Each week, five birds from each group were euthanased by cervical dislocation to obtain intestinal length, the mucous area, crypt’s depth, villus height and percentage of cells in proliferation activity. A completely randomized design was used in a factorial schema 6 x 2 (six ages: one, seven, 14, 21, 28 and 42 days and two ambient temperatures: thermoneutral and heat stress). Data were analyzed by analysis of variance and means compared by Tukey test at 5%. The birds stressed by heat presented less crypt depth, mucous area and villus height of duodenum and lower intestinal length at 42 days old. However, heat stress did not influence the percentage of PCNA positive cells, the area of the mucosa, crypt’s depth and villus height in jejunum and ileum.
Origin-related, environmental, sex, and age determinants of immunocompetence, susceptibility to ectoparasites, and disease symptoms in the barn owl

Knowledge of the role of origin-related, environmental, sex, and age factors on host defence mechanisms is important to understand variation in parasite intensity. Because alternative components of parasite defence may be differently sensitive to various factors, they may not necessarily covary. Many components should therefore be considered to tackle the evolution of host-parasite interactions. In a population of barn owls (Tyto alba), we investigated the role of origin-related, environmental (i.e. year, season, nest of rearing, and body condition), sex, and age factors on 12 traits linked to immune responses [humoral immune responses towards sheep red blood cells (SRBC), human serum albumin (HSA) and toxoid toxin TT, T-cell mediated immune response towards the mitogen phytohemagglutinin (PHA)], susceptibility to ectoparasites (number and fecundity of Carnus haemapterus, number of Ixodes ricinus), and disease symptoms (size of the bursa of Fabricius and spleen, proportion of proteins that are immunoglobulins, haematocrit and blood concentration in leucocytes). Cross-fostering experiments allowed us to detect a heritable component of variation in only four out of nine immune and parasitic parameters (i.e. SRBC- and HSA-responses, haematocrit, and number of C. haemapterus). However, because nestlings were not always cross-fostered just after hatching, the finding that 44% of the immune and parasitic parameters were heritable is probably an overestimation. These experiments also showed that five out of these nine parameters were sensitive to the nest environment (i.e. SRBC- and PHA-responses, number of C. haemapterus, haematocrit and blood concentration in leucocytes). Female nestlings were more infested by the blood-sucking fly C. haemapterus than their male nestmates, and their blood was less concentrated in leucocytes. The effect of year, season, age (i.e. reflecting the degree of maturation of the immune system), brood size, position in the within-brood age hierarchy, and body mass strongly differed between the 12 parameters. Different components of host defence mechanisms are therefore not equally heritable and sensitive to environmental, sex, and age factors, potentially explaining why most of these components did not covary.

Value of Area Postrema Syndrome in Differentiating Adults With AQP4 vs. MOG Antibodies

Objectives: To compare the frequency of area postrema syndrome (APS) in adults with anti-aquaporin-4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies. Methods: APS is defined as acute or subacute, single or combined, episodic or constant nausea, vomiting, or hiccups, persisting for at least 48 h, which cannot be attributed to any other etiology. The presence of APS was investigated in 274 adults with AQP4 antibodies and 107 adults with MOG antibodies from 10 hospitals. Results: The study population comprised Korean adults (≥18 years). At the time of disease onset, 14.9% (41/274) adults with AQP4 antibodies had APS, while none of the participants with MOG antibodies developed APS (p < 0.001). During the course of the disease, 17.2% (47/274) adults with AQP4 antibodies had APS in contrast to 1.9% (2/107) adults with MOG antibodies with APS (p < 0.001). Conclusions: APS, one of the core clinical characteristics of individuals with AQP4 antibodies, is an extremely rare manifestation in Korean adults with MOG antibodies.
Endocrine disrupting effects on the nesting behaviour of male three-spined stickleback Gasterosteus aculeatus L

The analysis of patterns of temporal variability in the nesting behaviour of male three-spined stickleback Gasterosteus aculeatus exposed to the synthetic oestrogen, 17β-ethinylestradiol, revealed immediate, but transient, treatment-related effects. Glueing frequency and time spent near nest were significantly reduced in exposed fish at the beginning of the experiment. The expression of these behaviours subsequently recovered and there was no effect of treatment on nest building success.
Chinese Font Recommendation Based on Emotional Adjectives

A recommendation system is designed for users to make better choices and find what they need. At present, there are few studies on the design of recommendation systems for Chinese fonts based on emotional adjectives. Therefore, this study proposes a recommendation method for Chinese fonts based on emotional adjectives and establishes an emotional classification algorithm as well as a font assignment module, which delivers different font results according to the emotional descriptive sentences that are typed in. The method proposed by this study has demonstrated good results in preliminary experiments. A complete experiment will be conducted to verify the effect of this recommendation method for Chinese fonts.
Competing with Whom? Where? and Why (Not)? an Empirical Study of U.S. Online Newspapers’ Competition Dynamics

Abstract As a newspaper Web site theoretically may compete with anything and everything, online and offline, this study empirically examines the nature, degree, and locale of online newspaper competition. Based on online reader survey data collected from users of 27 local U.S. newspaper Web sites, this study seeks to capture the competitive relationship between the local newspaper site and other online/offline news sources among local and long-distance users. A competitive relationship between the newspaper site and its print counterpart in the local market was found among about one third of the cases, after controlling for demographics and Internet use. Theoretical and managerial implications are discussed.
The Role of Nitric Oxide in Nitrogen Fixation by Legumes

The legume-rhizobia symbiosis is an important process in agriculture because it allows the biological nitrogen fixation (BNF) which contributes to increasing the levels of nitrogen in the soil. Nitric oxide (⋅NO) is a small free radical molecule having diverse signaling roles in plants. Here we present and discuss evidence showing the role of ⋅NO during different stages of the legume-rhizobia interaction such as recognition, infection, nodule development, and nodule senescence. Although the mechanisms by which ⋅NO modulates this interaction are not fully understood, we discuss potential mechanisms including its interaction with cytokinin, auxin, and abscisic acid signaling pathways. In matures nodules, a more active metabolism of ⋅NO has been reported and both the plant and rhizobia participate in ⋅NO production and scavenging. Although ⋅NO has been shown to induce the expression of genes coding for NITROGENASE, controlling the levels of ⋅NO in mature nodules seems to be crucial as ⋅NO was shown to be a potent inhibitor of NITROGENASE activity, to induce nodule senescence, and reduce nitrogen assimilation. In this sense, LEGHEMOGLOBINS (Lbs) were shown to play an important role in the scavenging of ⋅NO and reactive nitrogen species (RNS), potentially more relevant in senescent nodules. Even though ⋅NO can reduce NITROGENASE activity, most reports have linked ⋅NO to positive effects on BNF. This can relate mainly to the regulation of the spatiotemporal distribution of ⋅NO which favors some effects over others. Another plausible explanation for this observation is that the negative effect of ⋅NO requires its direct interaction with NITROGENASE, whereas the positive effect of ⋅NO is related to its signaling function, which results in an amplifier effect. In the near future, it would be interesting to explore the role of environmental stress-induced ⋅NO in BNF.
Revised Energy Conversion Factor for Inulin-Type Fructans and Implications for Resource Ranking in Optimal Foraging Theory

Current conversion factors for calculating the contribution of carbohydrates to food energy are reviewed in light of recent advances in food science. The undigested carbohydrate inulin, which is present in many economically important plants, resists digestion by alimentary enzymes in the upper gastrointestinal system of humans, and reaches the colon chemically intact where it undergoes partial or complete fermentation by endogenous bacterial flora. Current internationally accepted conversion factors for estimating energy (calories) specify that all carbohydrates provide 4 kcal per gram. However, inulin-type fructans fulfill all necessary criteria as a dietary fiber and during fermentation produce short-chain fatty acids that are utilized by the host for energy and should be assigned the energy conversion factor of 1.5 kcal per gram. The significance of assigning 1.5 kcal per gram vs. 4 kcal per gram to this carbohydrate when ranking resources in optimal foraging theory is illustrated in the caloric return rate of two commonly pit-baked desert plants from semi-arid North America.
Floral Development Reveals the Existence of a Fifth Staminode on the Labellum of Basal Globbeae

We observed the floral development of Hemiorchis burmanica and two species of Gagnepainia, which make up the sister group of Globba in Globbeae, as well as a selected number of species of Globba. Our observations revealed that in Gagnepainia, a “fifth staminode,” develops as part of the labellum, while it is generally lost in other Zingiberaceae. The fifth staminode, however, was not initiated in the labellum of Hemiorchis. A fifth staminode was also observed in Globba geoffrayi but was not found in all other species of Globba investigated. While the staminode becomes an integral part of the labellum in Gagnepainia, it remains small and almost aborts at later stages of development in G. geoffrayi. These results indicate that the development of a fifth staminode could be a recurring plesiomorphic trait for Globbeae, only retained in G. geoffrayi. The retention of the fifth staminode and its heterochronic shift may be linked with the mechanical constriction within the flower bud. The results may also support the interpretation of an atavistic expression of a once lost staminode.
Temperature effects on seed color in black- and yellow-seeded rapeseed

The effects of growth temperature on seed color of two black- and four yellow-seeded doubled-haploid genotypes of Brassica napus were examined with plants grown at 16/12, 18/14, 20/16, 22/18 and 24/20 °C (day/night). High temperatures significantly reduced seed color that developed on yellow-seeded genotypes but did not alter seed color produced on black-seeded genotypes. The decrease in pigmentation measured with a modified near-infrared reflectance analyzer was linearly related to temperature for the yellow-seeded genotypes. Significant differences in the magnitudes of the response were observed among the yellow-seeded genotypes. This is the first systematic study of temperature effects on seed color in rapeseed. The results confirm previous preliminary reports of environmental modifications of this trait. The study also illustrates a method for determining temperature effects on seed-color expressivity that may be useful for plant breeding programs. Key words: Temperature, Brassica napus, seed color
