Combining rule-based and bag-of-words for phase-level sentiment analysis of blog comments

Blogs are one of the platforms that express personal opinions, which are intended to create awareness and used as an instrument to establish trust among customers products and services or about a specific topic. A new classifying model was experimented to improve the sentiment classification of the blog comments. This technique combined Rule-Based (RB) and Bag-of-Word (BoW) model to solve major weaknesses of this Bow model in the conduct of Sentiment Analysis (SA) evaluations. The proposed technique was experimented to esti-mate the Philippine Internet customers’ satisfaction related to the quality of the services provided by the ISPs in the Philippines. In addition, automatic word seeding, building of sentiment dictionary utilizing an online dictionary, n-gram, tokenization, stemming and other SA tech-niques were applied to extract useful information from the blog comment dataset. The results of the research showed that the configurations involving BoW-RB + SVM + bi-gram + Porter stemmer achieved a high classification accuracy of 88%. Capturing the contextual meaning of the neighboring words of a given sentimental word provides a significant help to increase the classifi-cation performance of the proposed classifier method.
Habitat‐dependent occupancy and movement in a migrant songbird highlights the importance of mangroves and forested lagoons in Panama and Colombia

Abstract Climate change is predicted to impact tropical mangrove forests due to decreased rainfall, sea‐level rise, and increased seasonality of flooding. Such changes are likely to influence habitat quality for migratory songbirds occupying mangrove wetlands during the tropical dry season. Overwintering habitat quality is known to be associated with fitness in migratory songbirds, yet studies have focused primarily on territorial species. Little is known about the ecology of nonterritorial species that may display more complex movement patterns within and among habitats of differing quality. In this study, we assess within‐season survival and movement at two spatio‐temporal scales of a nonterritorial overwintering bird, the prothonotary warbler (Protonotaria citrea), that depends on mangroves and tropical lowland forests. Specifically, we (a) estimated within‐patch survival and persistence over a six‐week period using radio‐tagged birds in central Panama and (b) modeled abundance and occupancy dynamics at survey points throughout eastern Panama and northern Colombia as the dry season progressed. We found that site persistence was highest in mangroves; however, the probability of survival did not differ among habitats. The probability of warbler occupancy increased with canopy cover, and wet habitats were least likely to experience local extinction as the dry season progressed. We also found that warbler abundance is highest in forests with the tallest canopies. This study is one of the first to demonstrate habitat‐dependent occupancy and movement in a nonterritorial overwintering migrant songbird, and our findings highlight the need to conserve intact, mature mangrove, and lowland forests.
H3K9me2 protects lifespan against the transgenerational burden of germline transcription in C. elegans

During active transcription, the COMPASS complex methylates histone H3 at lysine 4 (H3K4me). In Caenorhabditis elegans, mutations in COMPASS subunits, including WDR-5, extend lifespan and enable the inheritance of increased lifespan in wild-type descendants. Here we show that the increased lifespan of wdr-5 mutants is itself a transgenerational trait that manifests after eighteen generations and correlates with changes in the heterochromatin factor H3K9me2. Additionally, we find that wdr-5 mutant longevity and its inheritance requires the H3K9me2 methyltransferase MET-2 and can be recapitulated by a mutation in the putative H3K9me2 demethylase JHDM-1. These data suggest that lifespan is constrained by reduced H3K9me2 due to transcription-coupled H3K4me. wdr-5 mutants alleviate this burden, extending lifespan and enabling the inheritance of increased lifespan. Thus, H3K9me2 functions in the epigenetic establishment and inheritance of a complex trait. Based on this model, we propose that lifespan is limited by the germline in part because germline transcription reduces heterochromatin.
Productive performance, blood biochemical variables and immune responses of laying hens fed diets containing various fat sources

This study was conducted to evaluate the effects of various fat sources on productive performance, blood biochemical variables and immune responses of laying hens. Laying hens were divided into seven groups, which received i) basal or control diet (no oil); ii) and iii) basal diets containing 1% and 3% soybean (SB) oil; iv) and v) basal diets containing 1% and 3% kilka oil (KO), and vi) and vii) basal diets containing 1% and 3% soybean fatty acids (SFA). Productive performance was evaluated from day 1 to day 84. Blood biochemical variables and immune responses were assessed on days 28, 56 and 84 of the trial. The study results indicated that the dietary inclusion of 1% and 3% KO and SFA and 3% SB oil could decrease the feed conversion ratio (FCR) and increase egg production and egg mass in comparison with the control group throughout the study. Immune responses of sheep red blood cells and antibody titre against hemagglutination inhibition (HI) were significantly higher in laying hens fed KO and SFA and 3% SB oil compared with the control group. The serum concentrations of low density lipoprotein-C (LDL-C), very low density lipoprotein-C (VLDL-C) and malondialdehyde (MDA) were not influenced by the inclusion of oil sources. The serum concentration of cholesterol was increased significantly in laying hens that were treated with oil on day 28. The inclusion of fat sources significantly increased the serum concentration of HDL-C. The use of KO and SFA could be recommended at lower levels to improve the performance, immunity and some blood variables in laying hens. Keywords: egg production, kilka fish oil, lipid profile, soybean oil
Detection of multi‐people micro‐motions based on range–velocity–time points

The micro-Doppler effect is a useful signature for classifying various human behaviours. However, most micro-Doppler researches assume that only a single moving target exists during the observation. Their works lack in separating micro-motion features from multi-movers. When more than one target is present, their performance will deteriorate heavily. To address this issue, the authors design a new 3D (three-dimensional) model, range-velocity-time points, to separate and describe multi-mover micro-motions measured by the ultra-wideband radar. These 3D points contain the range-velocity-time information simultaneously. By dividing points in the 3D space instead of single Doppler domain, micro-Doppler signatures of each target can be separated effectively. Multi-people motion simulation results verify the effectiveness of the authors' method.
A Conceptual Framework for Range-Expanding Species that Track Human-Induced Environmental Change

For many species, human-induced environmental changes are important indirect drivers of range expansion into new regions. We argue that it is important to distinguish the range dynamics of such species from those that occur without, or with less clear, involvement of human-induced environmental changes. We elucidate the salient features of the rapid increase in the number of species whose range dynamics are human induced, and review the relationships and differences to both natural range expansion and biological invasions. We discuss the consequences for science, policy and management in an era of rapid global change and highlight four key challenges relating to basic gaps in knowledge, and the transfer of scientific understanding to biodiversity management and policy. We conclude that range-expanding species responding to human-induced environmental change will become an essential feature for biodiversity management and science in the Anthropocene. Finally, we propose the term neonative for these taxa.
Analysis of yield traits, oil content and protein concentration in canola (Brassica napus L.) in relation to various nitrogen and seed rates

Nitrogen plays an important role in protein formation, cell improvement, protoplasm and other photosynthetic activities. Therefore, a field study was conducted at Bacha Khan Agricultural Research Farm, Bacha Khan University, Charsadda, during 2015-2016. The experiment was laid down according to Randomized Complete Block design (RCBD) having three replications with plot size of 1.5m x 4m. Two factors were studied, i.e. Nitrogen levels (0, 50, 75 & 100 kg ha) and Seed rates (3, 6 and 9 kg ha). Seed rates resulted in maximum emergence (55 m), plant height (147 cm), thousand grains weight (3.4 g) and grain yield (2026 kg ha) were recorded with seed rate of 9 kg ha while minimum days to maturity (155), maximum oil content (45%), Absolute growth rate (AGR) (7.4 g m day), grain nitrogen content (2.6 %) and straw nitrogen content (1.5 %) were recorded with the seed rate of 3 followed by 6 kg ha. Except emergence, nitrogen performed better and maximum plant height (147 cm), 1000 grains weight (3.5 g), grain yield (2211 kg ha), Absolute growth rate (AGR) (10.3 g m day), Nitrogen content in grain (2.7 %) and nitrogen content in straw (1.6 %) were achieved with 100 kg N ha while minimum days to maturity (155) and grain oil content (44%) were obtained with 50 kg N ha. Grain yield and oil content of canola increased with seed rate 6 kg followed by 9 kg ha while 100 & 50 kg N ha enhanced grain yield & oil content.
Stochastic delays suppress noise in a genetic circuit with negative feedback

We consider a mechanistic stochastic model of an autoregulatory genetic circuit with time delays. More specifically, a protein is expressed in random bursts from its corresponding gene. The synthesized protein is initially inactive and becomes active after a time delay. Rather than considering a deterministic delay, a key aspect of this work is to incorporate stochastic time delays, where delay is an independent and identically distributed random variable. The active protein inhibits its own production creating a negative feedback loop. Our analysis reveals that for an exponentially-distributed time delay, the noise in the protein levels decreases to the Poisson limit with increasing mean time delay. Interesting, for a gamma-distributed time delay contrasting noise behaviors emerge based on the negative feedback strength. At low feedback strengths the protein noise levels monotonically decreases to the Poisson limit with increasing average delay. At intermediate feedback strengths, the noise levels first increase to reach a maximum, and then decease back to the Poisson limit with increasing average delay. Finally, for strong feedbacks the protein noise levels monotonically increase with the average delay. For each of these scenarios we provide approximate analytical formulas for the protein mean and noises levels, and validate these results by performing exact Monte Carlo simulations. In conclusion, our results uncover a counter intuitive feature where inclusion of stochastic delays in a negative feedback circuit can play a beneficial role in buffering deleterious fluctuations in the level of a protein.
Evaluation of Secondary Metabolites in Wheat Grain (Triticum Sp.) Grown in Humid South Eastern Plain Zone of Rajasthan (India)

Cereal crops such as wheat, rice and barley underpin the staple diet for human consumption, globally. In India, wheat is qualitatively a major source of macromolecule, energy and fiber for human community nutrition since long time hence, preferably used as a staple food grain for society and also used as major source of fodder for animal feeding. The health benefits of whole grains are linked to the existence of secondary bioactive metabolites including phenolic acids, flavonoids and phytosterols. Flavonoids have the properties like anti-inflammatory, antioxidant, antiallergic, antithrombotic, antiviral and anticarcinogenic activities. Quercetin is one with an average of daily consumption of 25 mg to 40 mg. Kaempferol used as an antioxidant. Quantification data revealed that the total flavonoid content (free + bound) was observed highest and lowest in durum genotypes of HD 4728 (1.75 mg/gdw) and Raj 6560 (0.92 mg/gdw), respectively and in aestivum genotypes Raj 4037 (1.38 mg/gdw) and HI 1544 (0.72 mg/ gdw) gave similar trend. Regular daily intakes of whole grain products are associated with reduced risk of several diseases. The objective of this study was identification and characterization of secondary metabolites i.e. flavonoids in Triticum sp.
miRNA858b Inhibits Proanthocyanidin Accumulation by Repression of DkMYB19 and DkMYB20 in Persimmon

Persimmon proanthocyanidin (PA) biosynthetic had been reported to be regulated by several transcription factors, but the miRNAs function involved in this process was poorly understood. We identified a miRNA858b that putatively targeted two R2R3-MYB transcription factors, DkMYB19/DkMYB20. Transcript accumulation of DkMYB19/DkMYB20 and miRNA858b showed contrasting divergent expression patterns during fruit development. DkMYB19/DkMYB20 were confirmed to be localized in the nucleus. The interaction between miRNA858b and DkMYB19/DkMYB20 were experimentally validated by 5’ RNA ligase-mediated RACE and LUC enzyme activity detection. Overexpression of miRNA858b led to the down-regulation of DkMYB19/DkMYB20 which reduced the accumulation of PA, whereas the reduced miRNA858b activity that up-regulated the DkMYB19/DkMYB20 resulted in high levels of PA in STTM858b transient expression in leaves in vivo. Similarly, the transient transformation of miRNA858b in fruit wafers in vitro also reduced the accumulation of PA by repressing the DkMYB19/DkMYB20, while the up-regulation of DkMYB19/DkMYB20 enhanced the accumulation of PA in STTM858b or DkMYB19/DkMYB20 transient transformation in fruit wafers. PA content decreased after overexpression of miRNA858b in Arabidopsis wild type and DkMYB19/DkMYB20 in persimmon leaf callus consisted with the above results. These findings suggested that miRNA858b repressed the expression of DkMYB19/DkMYB20 which contribute to PA accumulation in persimmon.
The Tgf-β1 Over Expression has Major Impact on Multilineage Differentiation of Mesenchymal Stromal Cells

with a superior capacity for self-renewal, and are capable of differentiating into adipocytes, osteoblasts, chondrocytes [1,2]. In these days, MSCs have been broadly used in regenerative medicine [3]. Dental Pulp-derived Mesenchymal Stem Cells (DPSCs) have become a popular research topic in that they are similar too the rmesenchymal stem cells, easy to obtain and are used in regenerative medicine and tissue engineering [4]. In vitro and in vivo studies have been previously performed to understand the biology of DPSCs. The differentiation of mesenchymal stem cells usually involves the use of signaling factors as recombinant proteins or gene therapy that an functionally activate genes [5]. Transforming Growth Factor Beta 1 (TGF-β1) activates mainly SMAD transcription factors with complex cellular responses [6]. The superior proliferative ability and regenerative potential are primary phenotypes of MSCs [7].
THE WEIGHTS OF MALE CROSSBREED NURSING PIGLETS AFTER GIVEN FEED ENZYMES AND TURMERIC FLOUR

This study aims to determine the effect of the addition of feed enzymes containing xylanase, amylase and protease with turmeric flour (Curcuma domestica) to increase the body weight of male crossbreed nursing piglets. Using a completely randomized design, thrty-two male crossbreed piglets aged four weeks weighing 7-9 kg were divided into four groups (P0, P1, P2 and P3) with eight replications. The enzymes and turmeric flour are given through feed for five weeks. Group P0 as a control given feed without treatment. Group P1 was given enzyme dose 0.1% of feed. Group P2 was given turmeric flour dose 1% of feed. Group P3 was given a combination of enzymes and turmeric flour with a dose 0.1% and 1% of feed. Data on absolute growth of piglets was obtained from the difference in weighing the initial with the final body weight. The mean of body weight gain as follows P0 = 14.81 ± 1.11; P1 = 15.99 ± 1.79; P2 = 16.94 ± 0.84 and P3 = 17.68 ± 1.62 kg. Statistical analysis showed that the addition of enzymes and turmeric flour through feed had a significant effect on the weight of the nursing piglets. The best results on the combination treatment of feed enzymes and turmeric flour with a dose of 0.1% and 1% of feed.
The microRNA bantam promotes nighttime sleep through multiple mushroom body output neurons in Drosophila melanogaster

microRNAs play an important role in the regulation of sleep. Previous studies have identified bantam as a sleep-promoting microRNA in Drosophila. We sought to characterize the role of bantam in sleep regulation by identifying which neurons require bantam for normal sleep maintenance and determining the cellular and molecular mechanisms through which bantam regulates sleep. Using split-GAL4 lines to express a bantam inhibitor (sponge) in a cell-specific manner, we found that bantam regulates sleep through multiple mushroom body output neurons (MBONs), a class of neurons previously implicated in sleep regulation. To determine whether bantam regulates the morphology of the MBONs, we imaged brains of flies co-expressing a fluorescent marker and the bantam sponge in MBONs of interest, and found that bantam does not regulate the gross morphology or cell number of the neurons tested in either the adult or developing fly. We employed two strategies to identify the mRNA targets of bantam: a bioinformatic pipeline to predict conserved targets of bantam, and RNA sequencing of γ2α’1 MBONs expressing the bantam sponge. Three potential sleep-relevant targets of bantam were identified: GAD1, Ptp69D, and fog. RNA sequencing identified 73 predicted targets of bantam that were upregulated in γ2α’1 MBONs expressing the bantam sponge, and gene ontology analysis predicted vesicle and active zone maintenance as potential biological pathways regulated by bantam in these MBONs. Our results identify a role for bantam in the adult regulation of sleep in specific subtypes of MBONs and identify GAD1, Ptp69D, and fog as potential mRNA targets of bantam.
Packet Length Covert Channels Crashed

Advanced developments in network security tools and techniques have inspired attackers to find alternative ways to bypass them. A network covert channel is a wide-open door for attackers to leak confidential information or to convey malicious activities without being detected. Moreover, the rapid development in network technology and its applications provides a rich platform for developing different covert channel scenarios. A packet length covert channel is a network illicit communication channel that is featured as one of the most difficult covert channels to detect. It generates a covert traffic that is typically similar to normal traffic; this renders such a channel to be virtually impossible to discover. This paper investigates one type of packet length covert channels which exploits the variation of the network packets’ lengths to convey secret messages this type of covert channels does not need any rules to be distributed prior to the initiation of a covert session as other packet length covert channels need. The paper contributes by presenting an elimination approach to resolve this type of covert channel. This approach is sufficiently capable to completely distort the communication session between any sender and receiver who wish to establish such a covert channel. The proposed approach is successfully tested and validated.
Processive activity of the replicative DNA polymerases in the replisome of live eukaryotic cells

DNA replication is carried out by a multi-protein machine called the replisome. In Saccharomyces cerevisiae, the replisome is composed of over 30 different proteins arranged into multiple subassemblies, each performing distinct activities. Synchrony of these activities is required for efficient replication and preservation of genomic integrity, but how this is achieved remains an open question. Here we established novel single-molecule fluorescence microscopy protocols to study the binding kinetics of individual replisome subunits in live S. cerevisiae. Our results show long residence times for most subunits at the active replisome, supporting a model where all subassemblies bind tightly and work in a coordinated manner for extended periods, hence defining the architecture of the active eukaryotic replisome. One sentence summary Stable binding of DNA polymerases at the active eukaryotic replisome explains processive DNA synthesis on both strands
Local adaptation to abiotic and biotic stresses and phenotypic selection on flowering time in annual Brachypodium spp. along an aridity gradient

Plants have diverse strategies to cope with stress, including early flowering to “escape” abiotic stress and late flowering to mitigate biotic stress. Plants are usually exposed to multiple stresses simultaneously, but little is known about the impact of multiple co-occurring stresses on plant evolution. We tested for adaptation to both aridity and interspecific competition of the model plant Brachypodium spp. , collected along the aridity gradient in Israel. We recorded flowering time and estimated fitness in a controlled watering experiment, with treatments mimicking Mediterranean and arid precipitation, and in two common gardens located in the extremes of the gradient (i.e., desert and mesic Mediterranean). At the latter we also manipulated interspecific competition to examine the combined effect of competition and aridity. Plants from arid environments always flowered earlier, but we found no selection on flowering time in the watering experiment. In the common gardens, however, the direction of selection on flowering time differed between sites and competition treatments. We conclude that interactions between aridity and competition drive local adaptation of Brachypodium in the Eastern Mediterranean basin. Variation in flowering time is an important adaptive mechanism to aridity and multiple selection agents can have interactive effects on the evolution of this trait.
A Carrier Aggregation Transmitter Front End for 5-GHz WLAN 802.11ax Application in 40-nm CMOS

Carrier aggregation will be a key feature of the emerging 802.11ax system to boost data rate. Voltage-controlled oscillator (VCO) pulling and crosstalk between RF channels are two main problems related to carrier aggregation, which introduce severe impacts on adjacent channel leakage ratio (ACLR) and error vector magnitude (EVM). To address these two problems, high isolation between transmitter channels is required, but may not be realizable in some practical cases due to the constraint of the layout. This article presents a transmitter front end that can support two-carrier aggregation for 802.11ax without high on-chip isolation. The proposed transmitter front end employs a parallel direct conversion and double conversion configuration, and two carriers are combined before the power amplifier (PA). In this way, the intrinsic problems of VCO pulling and crosstalk can be mitigated. The proposed transmitter front end was implemented in a 40-nm CMOS technology. For contiguous intraband carrier aggregation with VHT80, MCS9 signals [80-MHz bandwidth, 256-quadrature amplitude modulation (QAM), and 11.25-dB peak-to-average power ratio (PAPR)], the transmitter front end delivers an average output power of 5.3 + 4.8 dBm for two carriers with an EVM of ≤−32 dB, and the EVM can reach −36.1 dB.
