aDMSCN: A Novel Perspective for User Intent Prediction in Customer Service Bots

As one of the core components of customer service bot, User Intent Prediction (UIP) aims at predicting users? intents (usually represented as predefined user questions) before they ask, and has been widely applied in real applications. However, when developing a machine learning system for this problem, two critical issues, i.e., the problem of feature drift and class imbalance, may emerge and seriously deprave the system performance. Moreover, various scenarios may arise due to business demands, making the aforementioned problems much more severe. To address these two problems, we propose an attention-based Deep Multi-instance Sequential Cross Network (aDMSCN) to deal with the UIP task. On the one hand,the UIP task can be subtly formalized as multi-instance learning(MIL) task with an attention-based method proposed to alleviate the influences of feature drift. To the best of our knowledge, this is the first attempt to model the problem from a MIL perspective.On the other hand, a ratio-sensitive loss is also developed in our model, which can mitigate the negative impact of class imbalance. Extensive experiments on both offline real-world datasets and on-line A/B testing show that our proposed framework significantly out performs other state-of-art methods for the UIP task.
BotSpot: A Hybrid Learning Framework to Uncover Bot Install Fraud in Mobile Advertising

Mobile advertising has become inarguably one of the fastest growing industries all over the world. The influx of capital attracts increasing fraudsters to defraud money from advertisers. There are many tricks a fraudster can leverage, among which bot install fraud is undoubtedly the most insidious one due to its ability to implement sophisticated behavioral patterns and emulate normal users, so as to evade from detection rules defined by human experts. In this work, we propose an anti-fraud method based on heterogeneous graph that incorporates both local context and global context via graph neural networks (GNN) and gradient boosting classifier to detect bot fraud installs at Mobvista, a leading global mobile advertising company. Offline evaluations in two datasets show the proposed method outperforms all the competitive baseline methods by at least 2.2% in the first dataset and 5.75% in the second dataset given the evaluation metric Recall@90% Precision. Furthermore, we deploy our method to tackle million-scale data daily at Mobvista. The online performance also shows that the proposed methods consistently detect more bots than other baseline methods.
Camellia as an Oilseed Crop

Camellia is one of the four main oil-bearing trees along with olive, palm, and coconut in the world. Known as ‘‘Eastern Olive Oil,’’ camellia oil shares similar chemical composition with olive oil, with high amounts of oleic acid and linoleic acid and low saturated fats. Camellia was ﬁrst exploited for edible oil in China more than 1000 years ago. Today, its oil serves as the main cooking oil in China’s southern provinces. Introduction of camellia oil into the Western countries was delayed until the recognition of its many health beneﬁts. Although popularity for the oil has yet to grow outside of China, interest has emerged in commercial production of camellia oil in other countries in recent years. Unlike seed-oil plants that are grown on arable land, oil camellias normally grow on mountain slopes. This allows the new crop to take full usage of the marginal lands. To facilitate promoting this valuable crop as an alternative oil source and selecting promising cultivars for targeted habitats, this paper reviews the resources of oil camellias developed in China, use of by-products from oil-reﬁning process, as well as the progress of developing camellias for oil production in China and other nations. The genus Camellia comprises a group of about 100 species native to a number of areas throughout China, southeast Asia, and Japan (Min and Bartholomew, 2007; Ming, 2000). They are evergreen ﬂowering trees or shrubs with broad, shiny, dark green leaves, and have primarily a subtropical and warm- temperate distribution. Among them, Camellia sinensis and Camellia japonica are the best internationally known and cultivated species, for tea production and ornamental value, respectively. These two
Differential growth rate influences dispersal potential of queen conch larvae

Spatial differences in phytoplankton biomass and quality caused variation in the larval life-span of queen conch, Strombus gigas. Conch larvae were grown in the laboratory on three assemblages of phytoplankton: 1) seawater from the Great Bahama Bank, 2) seawater from the Exuma Sound shelf, and 3) an algal mixture of cultured Caicos Isochrysis and Chaetoceros gracilis. Larvae in a field mesocosm system were also fed a continuous supply of natural phytoplankton from Bahamian Bank water. In the mesocosm system larvae acheived metamorphic competence in only 13 days. In the laboratory, larvae in the Bank and cultured algal treatments acheived competence in 20 days, but none in the shelf water ever became competent. Individual variation within a cohort occurred in all treatments, with the largest larvae in each treatment approximately twice the size of the smallest. The results suggest that duration of larval life-span for conch larvae could range from 13 to 83 days, if growth was linear. The magnitude of this range means that larvae have the potential to metamorphose in local waters or be transported between countries in the Caribbean. To understand larval recruitment, both larval development and transport processes need to be considered.
Resource Use Efficiencies of C3 and C4 Cereals under Split Nitrogen Regimes

Resources are limited, thus improving resource use efficiency is a key objective for cereal-based cropping systems. This field study was carried out to quantify resource use efficiencies in selected C3 and C4 cereals under split nitrogen (N) application regimes. The study included the following treatments: six cereals (three C3: wheat, oat, and barley; and three C4: maize, millet, and sorghum) and four split N application regimes (NS1 = full amount of N at sowing; NS2 = half N at sowing + half N at first irrigation; NS3 = ⅓ N at sowing + ⅓ N at first irrigation + ⅓ N at second irrigation; NS4 = ¼ N at sowing + ¼ N at first irrigation + ¼ N at second irrigation + ¼ N at third irrigation). Results revealed that C4 cereals out-yielded C3 cereals in terms of biomass production, grain yield, and resource use efficiencies (i.e., radiation use efficiency (RUE) and nitrogen use efficiency (NUE)), while splitting N into three applications proved to be a better strategy for all of the selected winter and summer cereals. The results suggest that C4 cereals should be added into existing cereal-based cropping systems and N application done in three installments to boost productivity and higher resource use efficiency to ensure food security for the burgeoning population.
Combining Ability and Genetic Control of Pod Yield and Component Traits in Dolichos Bean

ABSTRACT The major limitation of dolichos bean (Dolichos lablab L.) improvement is the narrow genetic base for useful traits present in available germplasm that may be overcome through interspecific hybridization. Five diverse genotypes involving two each of indeterminate and semi-indeterminate, and one determinate type, were crossed in a 5 × 5 half diallel mating design to estimate combining ability, mode of gene action, and extent of heterosis for 12 quantitative traits. The preponderance of additive genetic effects was evident for pod weight and number of pods/inflorescence; additive and non-additive gene effects for number of pods/plant, and non-additive gene action in expression of days to 50% flowering, raceme length, number nodes/inflorescence, number inflorescences/plant, number flower buds/inflorescence, pod length, pod diameter, pod thickness, and pod yield/plant. The parents “BCDB 10” and “BCDB-2” were identified as potential donors for breeding. The crosses “BCDB-2×BCDB-15” and “BCDB-10×BCDB-5” exhibited high heterobeltiosis for pod yield/plant to the extent of 114.26 and 86.63%, respectively. They could not be exploited at the commercial level. These crosses involved one parent having high general combining ability effects for pod yield and other important horticultural traits that could produce desirable transgressive segregants in subsequent generations.
Monitoring of quantitative and qualitative losses by lepidopteran, and homopteran pests in different crop production systems of Brassica oleracea L.

The present study was conducted in 2014-2015 to assess seasonal qualitative and quantitative losses by insect pests in different crop production systems of Brassica oleracea. The experiment was conducted on Entomological Research Area Young Wala, Department of Entomology, University of Agriculture Faisalabad the experiment was comprised of five treatments each had comprised of 68 plants grown in four rows. Plant to plant and row to row distance was maintained as 0.84 ft and 24 ft respectively. First season experimentation results showed the highest yield of Brassica oleracea in grower standard (2.24%) cultivation method second season experimentation showed maximum yield (1.92%) in reducing risk pesticides cultivation method. On basis of results present study suggests reduced risk pesticides and grower standard cultivation methods are better than other treatments because less qualitative and quantitative losses were observed in these treatments.
Phylogenetic association of Schizothorax plagiostomus with other schizothoracine fishes based on mitochondrial cytochrome B gene and control region

Abstract Cytochrome B (Cyt B) gene and control region of mitochondrial DNA are considered important for evaluating phylogenetic association of a species. In this study, we sequenced Cyt B and control region of Schizothorax plagiostomus and constructed phylogenetic association tree of S. plagiostomus with 23 schizothoracine fishes. We found S. plagiostomus to be closely associated with S. labiatus, S. richardsonii, S. progastus, and S. esocinus, with high-bootstraps values. Several conserved sequence blocks were identified within D-loop sequences. These are highly conserved within genus Schizothorax compared to other. This study reports the phylogenetic position of the S. plagiostomus among schizothoracines fishes and organization of D-loop region in S. plagiostomus from Pakistan.
Selection of horizontal gene transfer through public good production

In bacteria, cooperative genes encoding public good molecules are preferentially located on mobile genetic elements (MGEs), and horizontal transfer of MGEs favours the maintenance of public good cooperation. The rate of horizontal transfer itself can evolve in response to selective pressures acting on both MGEs and bacterial hosts: benefits and costs of infectious spread, but also indirect effects of MGE genes to the host. We show here that carriage of public good genes on MGEs can generate another indirect selection for MGE transfer. Transfer increases public good production and, when relatedness is sufficiently high, public goods benefit preferentially genotypes with high transfer ability. Both our simulations and experiments indicate that transfer is not required to occur among kin, provided that public goods still benefit kin. Public good gene mobility thus aligns the interests of chromosomes and MGEs concerning transfer, promoting gene exchange among bacteria.

Characterization of the polo like kinase Cdc5p and its influence on mitosis and morphogenesis in Candida albicans

Candida albicans is a commensal fungus in humans, but can cause infections with high mortality rates. Cell proliferation and differentiation between yeast and hyphae are important for virulence and survival in the host. An understanding of their regulation may reveal new targets for therapeutic strategies. My work aimed to elucidate the regulation of mitosis in C. albicans, a poorly understood process, and focussed on characterizing the roles of a Polo-like kinase (Plk), Cdc5p. Plks are critical regulators of many aspects of mitosis in diverse organisms. Previous work demonstrated that depleting Cdc5p in C. albicans yeast resulted in a block in spindle elongation and mitosis, followed by formation of filaments and expression of hyphal-specific virulence genes, under yeast growth conditions. However, the mechanisms underlying Cdc5p function, mitotic progression, formation of novel filaments and expression of virulence genes, remained unclear. In order to address these questions, I first investigated a putative Cdc5p target, the Anaphase-Promoting Complex/Cyclosome (APC/C). In Chapter 2, I showed that APC/C co-activators Cdc20p and Cdh1p had some conservation in mitotic function, and may lie downstream of Cdc5p. However, additional novel features suggest variations in the mitotic circuitry. I next investigated the identity of the Cdc5p-depleted filaments, since this was controversial. We hypothesized that the cells were elongated yeast buds that failed to switch from polar to isometric growth, but adapted a hyphal fate over time due to maintenance of polarized growth. In Chapter 3, time course assays demonstrated that hyphal-diagnostic features emerged in Cdc5p-depleted filaments at only later growth stages, in agreement with our hypothesis. Our results expand on the strategies that C. albicans can utilize to modulate growth and virulence determinants. I further addressed the mechanisms of Cdc5p function during mitosis and morphogenesis in Chapter 4 by screening for interacting factors. I discovered a novel, Candida-specific factor, CPI1 (C. albicans Plk-interacting protein), which was not essential for growth but required to maintain mitotic arrest and may interact with the splicesome. Collectively, the work enhances our knowledge of mitotic regulation in C. albicans, and underscores variations in the regulatory circuitry that have important implications for controlling growth.
Soil fungi underlie a phylogenetic pattern in plant growth responses to nitrogen enrichment

Under increasing anthropogenic nitrogen (N) deposition, some plant species will thrive while others will not. Previous work has shown that plant phylogeny can predict these responses, and that interactions with mycorrhizal fungi are a mechanism that drives variation in plant responses to N enrichment. Yet, much of this work has ignored the roles of other root‐associated fungi and whole soil fungal communities in driving these responses. We tested whether soil fungi mediate responses of plant growth and plant–soil feedbacks (between close and distant plant relatives) to N enrichment by implementing a greenhouse experiment in which we applied factorial treatments of N fertilization, host‐specific soil inocula and fungicide to 15 eucalypt tree species that co‐occur on the island state of Tasmania, Australia, and form two phylogenetic lineages within the subgenus Symphyomyrtus. Conspecific‐conditioned soil fungi enhanced growth responses to N enrichment for plants within one lineage (lineage 1) but depressed growth responses to N enrichment for plants within another lineage (lineage 2). Lineage‐specific shifts in ectomycorrhizal (ECM) colonization were consistent with previous evidence that more vs. less successful strategies under N enrichment are those where carbon allocation to mycorrhizal fungi is reduced vs. maintained, respectively. The latter was also accompanied by a stronger reduction in root colonization of non‐filamentous fungi (of unknown function) under N enrichment. Plant–soil feedbacks were neutral for lineage 1 but negative for lineage 2 (i.e. greater growth in soils conditioned by opposite vs. same lineage individuals), but were not altered by N enrichment or fungicide. Lineage‐level differences in root colonization suggest that these feedbacks could be driven by differential plant responsiveness to dark septate endophytes and non‐filamentous fungi, the colonization of which seemed to benefit plant growth. Synthesis: Our results confirm that interactions with soil fungi (ECM fungi, in particular) underlie phylogenetic patterns in tree species' growth responses to N enrichment and may, thus, influence which plants win or lose under future N deposition scenarios. Yet, we provide some of the first evidence (albeit from controlled rather than natural conditions) that N deposition may not play a strong role in shifting plant–soil feedbacks.

Reserpine treatment activates AMP activated protein kinase (AMPK)

− Reserpine is a well-known medicine for the treatment of hypertension, however the role of reserpine in cell signaling is not fully understood. Here, we report that reserpine treatment induces the phosphorylation of AMP activated protein kinase (AMPK) at threonine 172 (T172) in PC12 cells. Phosphorylation of AMPK T172 is regulated by upstream signaling molecules, and the increase of phospho-T172 indicates that AMPK is activated. When we examined the FOXO3a dependent transcription by using the FHRE-Luc reporter assay, reserpine treatment repressed the FHRE-Luc reporter activity in a dose dependent manner. Finally, we showed that reserpine treatment induced the phosphorylation of AMPK as well as cell death in MCF-7 cells. These results suggest that AMPK is a potential cellular target of reserpine.
Impact of Socio-Economic Factors on Sth Infection amongst Psac in Elburgon Municipality, Kenya

Socio-economic factors have been associated with high prevalence of soil transmitted helminthes infection in endemic areas. STH studies have been extensively conducted among school age children but non-school going children mostly those below five years and who actively play with soil are not common. In this study, 120 households in Elburgon Municipality were accessed using a structured question to determine the impact of these socio-economic factors on STH infection among pre-school age children. Kato Katz technique was used to determine the evidence of helminthes infection in 179 children who provided stool sample. The result from this study revealed that there was a general high prevalence 154 (86%) of STH infection with any of Trichuris trichura , Ascaris lumbricoides and hookworm or a combination of any two. The overall mother’s and father’s educational level and father’s occupation showed significant difference (p 0.05) in this children age group infection. In Elburgon Municipality, households are crowded in living conditions that can be termed as semi urban slums and children often play together in common play grounds. Regardless of both parent’s educational level and occupation STH infection in young children remained high because of common hygienically compromised environments. This study suggest that it might be difficult to improve the socio-economic status of populations living in semi-urban slum like households but frequent health education programs for both parents about these intestinal worms can be effective tool that will help in control STH infections in PSAC.

Screening of the Cervidae family in Poland for Mycoplasma species

Abstract Introduction: Several Mycoplasma species can cause severe diseases in ruminant hosts, some of which are the diseases listed by the World Organisation for Animal Health (OIE). The role of the Cervidae family in carrying and transmitting ruminant mycoplasma infections in Poland is unknown. Material and Methods: Antibody and antigen detection tests for the main mycoplasma species that can affect wild ruminants were performed on 237 samples (serum, nasal swab, bronchoalveolar lavage, and lung) collected from 161 animals during 2011-2014. The samples were obtained from a cull of healthy population of deer which included: 96 red deer (Cervus elaphus elaphus), 19 fallow deer (Dama dama), and 46 roe deer (Capreolus capreolus). Results: Serological screening tests revealed positive reactions to Mycoplasma bovis in one sample and to Mycoplasma capricolum subsp. capripneumoniae in three samples; however, these three samples were negative by immunoblotting. Other antibody and antigen detection tests demonstrated negative results. Conclusion: Currently wild cervids in Poland do not play a significant role in transmitting mycoplasma infections to domestic animals, but they remain a potential risk.
Coffee based polyphenols with potential in skin care : antioxidant activity and skin penetration assessed by in vivo Raman spectroscopy

ingredients of plant origin such as polyphenols and phenolic acids are enjoying increased acceptance in both the food and cosmetics industries. Their often excellent antioxidant properties are determined by in vitro assays. To develop an effective skin care formulation, their penetration ability and bioavailability has to be investigated as well. Both depend on molecular size, but also on the molecules’ balance of lipoand hydrophilicity. In this paper, the antioxidant activity of individual coffee fractions (roasted and unroasted) is compared by means of in vitro antioxidant assays, and the influence of the formulation on skin penetration of the antioxidant active is examined by in vivo Raman spectroscopy.
