CFDVex: A Novel Feature Extraction Method for Detecting Cross-Architecture IoT Malware

The widespread adoption of Internet of Things (IoT) devices built on different architectures gave rise to the creation and development of multi-architecture malware for mass compromise. Cross-architecture malware detection plays an important role in detecting malware early on devices using new or strange architectures. Prior knowledge of malware detection on traditional architectures can be inherited for the same task on new and uncommon ones. Basing on CFD and Vex intermediate representation, we propose a feature selection method to detect cross-architecture malware, called CFDVex. Experimental evaluation of the proposed approach on our large IoT dataset achieved good results for cross-architecture malware detection. We only trained a SVM model by Intel 80386 architecture samples, our method could detect the IoT malware for the MIPS architecture samples with 95.72% of accuracy and 2.81% false positive rate.
©Nigerian Mathematical Society ON THE STABILITY AND BOUNDEDNESS OF SOLUTIONS TO CERTAIN SECOND ORDER NONLINEAR STOCHASTIC DELAY DIFFERENTIAL EQUATIONS

This paper emphases on stability and boundedness of solutions to certain nonlinear non autonomous second order stochastic delay differential equations. A complete Lyapunov functional is constructed and used to establish conditions, on the nonlinear functions appearing in the equations, to guarantee stability and boundedness of solutions to the second order stochastic delay differential equations considered. The obtained results are new, complement and extend the existing results on second order stochastic delay differential equations in the literature. Finally, examples together with their numerical simulations are given to confirm genuineness and assert the correctness of the obtained results.
ADVERTISEMENT EFFECTIVITY: VISIBILITY, CREDIBILITY, ATTRACTION AND POWER ON PURCHASING DECISION AND ITS IMPACT ON CUSTOMER SATISFACTION

Promotion is a one-way flow of information or persuasion created to direct a person or organization to actions that create exchanges in marketing. From four types of promotions, the most effective way to promote is through advertising. An effective advertisement is an advertisement that enables to communicate (has attraction to read, the attraction of attitude, easy to be remembered, be seen, be noticed, read the most) and to effect on selling to what has been advertised. This study was aimed to find out the influences of Visibility, Credibility, Attraction and Power on Purchasing Decision and its impact on Customer Satisfaction. The method of study implemented was quantitative explanatory research with data analysis technique of Structural Equation Modelling using SMART PLS software. The result of study showed that the contribution of Visibility (X1), Credibility (X2), Attraction (X3), and Power (X4) simultaneously influenced that directly influenced on Purchasing Decision (Y), that obtained 42.2%. The rest of 57.8% was influenced by other factors that are not included in this study. Meanwhile, the contribution of Visibility, Credibility, Attraction, Power and Purchasing Decision simultaneously influenced that directly influenced on Customer Satisfaction that obtained 73.27%.

Determinants of Contraceptive Use among Women of Reproductive Age in Asankragwa in the Western Region of Ghana

Contraceptive use is an important intervention in reducing unplanned pregnancies and other sexually transmitted infections (STIs). This study investigates the knowledge of contraceptive use, identify the barriers of contraceptive use, and determine the predictors of contraceptive use among women in a peri-urban community in Ghana. Using a cross-sectional survey design, a total of 189 women of childbearing age was sampled in a peri-urban community in Ghana. Data were collected with questionnaires and analyzed using chi-square and binary logistic regression. The result shows that more than half of the participants ( 63.6% (n = 56) of contraceptive users knew seven to twelve types of contraceptives, whereas 46.6% of noncontraceptive users indicated they knew seven to twelve types of contraceptives. Knowledge of the types and uses of contraceptive was significantly associated with contraceptive usage. Spousal consent, adverse effects, lack of knowledge about the benefits and religion were the main barriers to contraceptive use. There was a strong association between marital status, income, age and contraceptive use among women (p <0.05). Women with no children and women with one to two children were 7 times (95%CI, 2.00, 27.78) more likely to use contraceptives. Those with more than three children were 11 times (95%CI 2.34, 54.87) more likely to use contraceptives. Although the women knew about the uses and types of contraceptives, utilisation was low. Parity was high among the factors that predicted the non-usage of contraceptives among women. The findings of this study call for a comprehensive education on contraceptives at various levels of the health delivery system.
INDICATORS OF PRODUCTIVE CLASSROOM TALK AND SUPPORTING DISCOURSE MOVES: A SYSTEMATIC REVIEW FOR EFFECTIVE SCIENCE TEACHING

This study intended to delve into productive classroom talk (PCT) typologies and sets of teacher discursive moves (TDMs) or talk moves supporting yielding dialogues in the context of teaching science. This study was arranged as an extended systematic review in which a content-based and thematically-oriented analysis of the selected works were carried out. Two frameworks; conceptual and technical, were invented and applied to the pooled studies. 67 research articles were selected from a larger pool and examined in a fine-grained manner. Five themes or indicators of the PCT were extracted. These are “clarity and intelligibility of the talks”, “critiques in the talk”, “accountability-justification-authority”, “intense discursively-oriented metacognitive activity” and “teacher as the discursive role model”. In addition, six sets of TDMs were extracted from the literature that are thought as supporting for the actualisation of a PCT indicator. These are “communicating”, “challenging”, “evaluating-judging-critiquing”, “monitoring-framing”, “seeking for evidence” and “modelling-rehearsing aspects of processes of science”. The relations between indicators of the PCT and supporting TDMs were reinterpreted by making concrete combinations and presenting in-class instances. It was concluded that several scholars worked through the generic lines of the PCT; however, within the examined studies, supporting TDMs were not attached to the productivity. One of the salient inferences of the present study is that whether science teachers hold a teacher-noticing pertaining the interrelations between the PCT and supporting TDMs. Several recommendations were offered for science teachers and science teacher educator particularly in terms of triggering and sustaining teacher-led noticing regarding rather sophisticated relationships the PCT and supporting TDMs. Practically, pedagogic noticing requires intentionality that is attainable in the presence of high quality professional development programs. © 2019 Published by Academy Journal of Educational Sciences.

Effect of feed Supplemented with Xylam Enzyme on Performance, Carcass Characteristics and Meat Quality of Broiler Chicks

This experiment was carried out to identify the impact of inclusion different levels of commercial xylam enzyme (zero, 0.5kg, 0.75kg, and 1 kg) in the feed on performance, carcass characteristics and meat quality of broiler chicks.300 unsexed oneday old (Ross 308) broiler chicks were used in the experiment. The chicks were randomly distributed to four dietary treatments and with each carrying 75 experimental birds. The treatments were subdivided into three replicates; each was given 25 experimental birds. All chicks were fed experimental diets to for five weeks which formulated according to (NRC) to meet the nutrient requirements. The results indicated that addition of xylam enzyme to diet improved significantly (p<0.05) the feed intake, body weight gain and feed conversion ratio values of broiler chicks throughout the experimental period. The results indicated that there were no significant differences between all treatment groups in percentages of commercial carcass cuts (breast, drumstick ,thigh and wing) and chemical composition of breast meat (moisture, fat, and ash), results also showed that no significant differences observed between all treatment groups in some physical properties of broiler breast meat (PH and WHC). It is concluded that adding (1 kg) of commercial xylam enzyme in broiler chicks diets resulted in economic benefits. ـــــــــــــــــــــــــــــــــــــــــ
Normal Aerobic Vaginal Bacterial Flora of The African Giant Rats (AGR) Captured from Their Natural Habitat in Abeokuta, Ogun State, Nigeria

The genital tract of female animals, especially the caudal region, is known to habour non specific bacteria that are sometimes called the normal bacterial flora. In this study, we examined 12 apparently healthy female African giant rats (Cricetomys gambianus, Waterhouse) (AGR) to determine their vaginal bacterial flora. Swab collected from the vagina of each rat after previous chloroform anaesthesia was seeded onto blood and MacConkey agar plates and incubated aerobically at 37 0 C for up to 48hours. Isolates were then characterized using various character parameters. The results indicated that 7 bacterial genera inhabit the vagina of the 12 African giant rats that were studied. The distribution of the bacteria species in the AGR were highlighted in the text. It is inferred from the results that under stress condition, these bacteria could cause disease in the African giant rats.

This comparative study fi nds the impact of perceived political, cultural, religious and economic factors on the perceived economic growth of Khyber Pakhtunkhwa, in the users of formal and informal fi nancial systems. A questionnaire was sent to 500 respondents selected as sample for the target population. Out of 500, 369 responded to the questionnaire. After scrutiny, 309 were found valid. The outcome of the study suggested a very strong strategic role of formal and informal fi nancial institutions in economic growth of the province . In this study, users of formal system showed a signifi cant impact of perceived political stability, perceived cultural stability , perceived religious stability and perceived economic growth on the economic growth of the province. In informal fi nancial system users, perceived economic stability, perceived political stability and perceived economic growth has signifi cant impact on the economic growth, where perceived religious stability has insignifi cant impact on economic growth. Difference between Perceived economic stability, Perceived political factors, perceived religious factors, and perceived cultural factors also found insignifi cant across the users of formal and informal fi nancial systems. However, the combination of the results were also associated with present political, cultural, religious and economic factors and the assumed results were debated with more implications at KP province.
Efficacy of Regenerative Materials and Ultrasonic Ridge Splitting Technique with Simultaneous Implants Placement into Narrow Alveolar Ridge

Aim: This study compares clinically and radiographically between efficacies of two different bone graft materials with amniotic membrane in narrow alveolar ridges subjected to ridge expansion by ultrasonic bone surgery to receive simultaneous implant placement. Subjects and Methods: Twenty-two systemically healthy patients with partial edentulous narrow anterior maxillary ridge classified randomly into the following equal groups: Group Ι patients with partial edentulous narrow ridge; treated by ridge splitting technique and simultaneous implant placement into their ridge; associated with deproteinized bovine bone (Bio-Oss ®) and amniotic membrane. Group II patients with partial edentulous narrow ridge; treated by ridge splitting technique and simultaneous implant placement into their ridge; associated with hydroxyapatite and 40% beta-tricalcium phosphate (easy-graft™ crystal) and amniotic membrane. Evaluation of implant success rate was done, and the clinical parameters were recorded for all implants. Implant stability quotient (ISQ) values was recorded. Efficacy of regenerative materials was observed by evaluation of marginal bone level and bone density. Results: Alveolar ridge width was increased in all groups. The mean value of alveolar ridge width in group I 3.64 mm ±0.3 at baseline that increased to 6.90mm ±0.6. The mean value of Alveolar ridge width in group II was 4.17 mm ±0.7at baseline that increased to 6.65 mm ±0.4. Group II showed the highest ISQ, bone density and the lowest marginal bone loss values after twelve months of implant placement. Conclusion: The use of piezo-electric surgery with bone grafting as sole tool for ridge splitting is promising technique.

Revisiting Nasal Coda Merger in Taiwan Mandarin: A Corpus Study

Taiwan Mandarin allows two nasal codas, [n] and [ŋ]. Previous studies revealed that possible place merger is correlated to sociolinguistic factors. To test whether incomplete neutralization of place contrasts occur acoustically, this study examines potential mergers by questioning whether words with nasal codas are truly merged. By using fine-grained acoustic analysis on a spoken corpus, we discovered that in many cases where neutralization was assumed, sounds are actually incompletely neutralized. Words with a mid vowel preceding the nasal coda tend to be phonetically reduced in connected speech (shortened in nasal murmur duration and produced with the least variation), while words with a low vowel preceding the nasal coda depend on the following place of articulation. Results provide evidence that various vowel heights use different acoustic correlates to maintain place distinctiveness; formant transition and nasal murmur alone are not enough to account for place contrasts in nasal codas in Taiwan Mandarin.
Rare earth elements in oyster shells: provenance discrimination and potential vital effects

Abstract. Rare earth elements (REEs) and yttrium in seawater originate from atmospheric fallout, continental weathering, and transport from rivers, as well as hydrothermal activity. Previous studies have reported the use of REE and Y measurements in biogenic carbonates as a means to reconstruct these surface processes in ancient times. As coastal seawater REE and Y concentrations partially reflect those of nearby rivers, it may be possible to obtain a regional fingerprint of these concentrations from bivalve shells for seafood traceability and environmental monitoring studies. Here, we present a dataset of 297 measurements of REE and Y abundances by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) from two species (Crassostrea gigas and Ostrea edulis). We measured a total of 49 oyster specimens from six locations in France (Atlantic Ocean and Mediterranean Sea). Our study reports that there is no significant difference in concentrations from shell parts corresponding to winter and summer periods for both species. Moreover, interspecific vital effects are reported from specimens from both species and from the same locality. REE and Y profiles as well as t-distributed stochastic neighbour embedding processing (t-SNE; a discriminant statistical method) indicate that REE and Y measurements from C. gigas shells can be discriminated from one locality to another, but this is not the case for O. edulis, which presents very similar concentrations in all studied localities. Therefore, provenance studies using bivalve shells based on REEs and Y have to first be tested for the species. Other methods have to be investigated to be able to find the provenance of some species, such as O. edulis.

The determination of optimum thermal insulation thickness for external walls of laying hen houses

One of the main objectives of the energy strategy of any country is conservation. Thermal insulation is of utmost importance in the context of energy conservation. Therefore, this study aims to optimize insulation layer for the ten cities of Turkey which have the highest number of laying hens. The yearly heating and cooling loads were determined by using degree day method. Then optimum insulation thickness, energy savings, payback periods and CO2 emission were computed for Rock wool (RW) and Glass wool (GW) insulation materials. Results indicated that the optimum thickness of insulation for RW insulation material varies between 0.046 and 0.159 m, energy savings range between 35.42% and 74.56%, and payback periods were between 0.67 and 2.00 years, while for GW insulation material optimum insulation thickness varies from 0.045 and 0.150 m, energy savings vary in the range of 42.17% and 77.72%, and payback periods were between 0.61 and 1.72 years depending on the city, and type of fuel. The lowest CO2 emission reductions (64.79%) were obtained for İzmir with natural gas and RW insulation material are used, while the highest value (88.76%) was achieved for Kayseri with LPG and GW insulation.

Survival and root structure changes of rice seedlings in different cultivars under submergence condition

Abstract. Rachmawati D, Maryani MM, Kusumadewi S, Rahayu F. 2019. Survival and root structure changes of rice seedlings in different cultivars under submergence condition. Biodiversitas 20: 3011-3017. Submergence affects plant growth and fitness in natural and agricultural ecosystem. Plant survival to submergence is strongly influenced by the water level and duration of submergence. The objective of this study was to determine the survivalysiological and root anatomical changes of two rice cultivars seedlings to submergence The experiment used completely randomized design with three factors, cultivar (IR-64’ and ‘Inpara 5’), depth and duration of submergence. Depth of submergence consisted of 3 levels: without, partial and complete submergence. Fourteen days old seedlings were treated for 5, 10 and 15 days of submergence. The observed parameters were seedling survival, chlorophyll content, soluble sugar and starch content, plant biomass, and root anatomical structure. The results showed that seedlings survival of ‘IR-64’ and ‘Inpara 5’ decreased by increasing depth and duration of submergence. Increasing depth of submergence decreased chlorophyll content, soluble sugar content and plant biomass. Anatomically, depth and duration of submergence showed a greater increased in root cortex thickness, aerenchyma tissue diameter and the percentage of cortex to be aerenchyma of rice ‘IR-64’ and ‘Inpara 5’. Fifteen days of complete submergence significantly decreased seedlings survival and increased the diameter of aerenchyma in both ‘IR-64’ and ‘Inpara 5’.
Effects of lead on some oxidative stress of the African catfish, Clarias gariepinus

This study aimed to determine the effects of sub-lethal concentrations of lead (PbCl2) on some oxidative stress in the African catfish Clarias gariepinus. Fishes were captured from Manzala Lake, Egypt. They were acclimatized and fed with commercial fish diet for one month before starting the experiment. Two experimental groups were exposed to two sublethal concentrations (10% and 30% of LC50) of lead chloride, fishes from different experimental groups were sacrificed after 60 days of exposure. Oxidative stress enzymes such as GSH, CAT, SOD, and MDA were estimated. Group treated with Pb10 % showed significantly lower concentrations of GSH. On the other hand, Pb 30% group showed a significantly higher concentration of CAT, MDA and SOD.
ESurf – Round of Reviews No . 2 – Minor Revisions

In bedrock rivers, erosion by abrasion is driven by sediment particles that strike bare bedrock while traveling downstream with 10 the flow. If the sediment particles settle and form an alluvial cover, this mode of erosion is impeded by the protection offered by the grains themselves. Channel erosion by abrasion is therefore related to the amount and pattern of alluvial cover, which are functions of sediment load and hydraulic conditions, and which in turn are functions of channel geometry, slope and sinuosity. This study presents the results of alluvial cover experiments conducted in a meandering channel flume of high fixed sinuosity. Maps of quasi-instantaneous alluvial cover were generated from time-lapse imaging of flows under a range of below15 capacity bedload conditions. These maps were used to infer patterns of particle impact frequency and likely abrasion rates. Results from eight such experiments suggest that: (i) abrasion through sediment particle impacts is driven by fluctuations in alluvial cover due to the movement of freely-migrating bars; (ii) patterns of potential erosion are functions of sediment load and local curvature; (iii) low sediment supply ratios are associated with regions of potential erosion located closer to the inner bank, but this region moves toward the outer bank as sediment supply increases; and (iv) the threads of high erosion rates are 20 located at the toe of the alluvial bars, just where the alluvial cover reaches an optimum for abrasion.
