Block Level TLB Coalescing for Buddy Memory Allocator

Conventional TLB (Translation Lookaside Buffer) coalescing schemes do not fully exploit the contiguity that a memory allocator provides. The conventional schemes accordingly have certain performance overheads due to page table walks. To address this issue, we propose an efficient scheme, called block contiguity translation (BCT), that accommodates the block size information in a page table considering the Buddy algorithm. By fully exploiting the block-level contiguity, we can reduce the page table walks as certain physical memory is allocated in the contiguous way. Additionally, we present unified per-level page sizes to simplify the design and better utilize the contiguity information. Considering the state-of-the-art schemes as references, the comparative analysis and the performance simulations are conducted. Experiments indicate that the proposed scheme can improve the memory system performance with moderate hardware overheads. key words: architectures, memory allocation, translation lookaside buffer, page table, performance
Simultaneous iterative solutions for the trust-region and minimum eigenvalue subproblem

ABSTRACT Given the inability to foresee all possible scenarios, it is justified to desire an efficient trust-region subproblem solver capable of delivering any desired level of accuracy on demand; that is, the accuracy obtainable for a given trust-region subproblem should not be partially dependent on the problem itself. Current state-of-the-art iterative eigensolvers all fall into the class of restarted Lanczos methods; whereas, current iterative trust-region solvers at best reduce to unrestarted Lanczos methods; which in this context are well known to be numerically unstable with impractical memory requirements. In this paper, we present the first iterative trust region subproblem solver that at its core contains a robust and practical eigensolver. Our solver leverages the recently announced work of Stathopoulos and Orginos which has not been noticed by the optimization community and can be utilized because, unlike other restarted Lanczos methods, its restarts do not necessarily modify the current Lanczos sequence generated by Conjugate Gradient methods (CG). This innovated strategy can be utilized in the context of TR solvers as well. Moreover, our TR subproblem solver adds negligible computational overhead compared to existing iterative TR approaches.
Postharvest treatments to preserve table grape quality during storage and 2 approaches to find better ways alternative for SO

Reliable knowledge on postharvest technology of table grapes could be an invaluable aid in maintenance of quality of commodities. For reasonably concrete estimates of postharvest preservation of produces, attention has to be devoted to harvesting and packaging strategies, effectiveness of various chemicals, and consideration of residuals of applications. A number of studies are currently available for the investigation of certain methods or applications to supply the grape year-round. Our literature investigations reveal that worldwide studies in 2 postharvest preservation of grapes still rely on the methodology based on sulphur dioxide (SO ) releasing pads. 2 In spite of its excellent responses to control decay, SO fumigation is becoming very restrictive in most 2 countries since SO residues are dangerous to people allergic to sulphites and may cause injuries to the rachis and berries. Thus present interest centers on the use healthy materials with safe, simple, and innovative technology. Results of recent studies indicate that there are many tools most of which promise better results 2 as alternative to SO . Especially, heat treatments, modified atmosphere packaging, ethanol, ozone, and chitosan (a natural polysaccharide) applications would be considered as healthy approaches when correctly used. Moreover, researchers usually recommended the use of combined tools to obtain better results. Key word: Grape storage, postharvest disorders, sulfur dioxide, postharvest applications
ROLE OF TRUST IN SMEs EXPORT PERFORMANCE

A large number of small and medium exporters have chosen partnership with local distributors/importers as a mean to expand overseas. This is mainly because of the positive impact of inter-organizational relationships on enhanced exporter’s ability to compete successfully in the marketplace. Extant literature has acknowledged the important of trust in developing and maintaining productive cross border business relationships. It is said that trust can be an effective tool in mitigating foreign partner opportunism and exporter’s competitiveness in foreign markets. Findings reveal that trust is directly related with export performance. In addition, trust also mediates the relationship between learning orientation and export performance. Furthermore, learning orientation is found to have direct effect on trust as well as export performance. Finally, implications and limitations are discussed and future study is proposed. Keywords—Export Performance, Inter-organizational, SMEs, Trust.

A New Method for a One-Shot Unblinded Sample Size Reassessment in Two-Group Trials : How & When ?

In two-group clinical trials, it has become usual, when performing a single interim unblinded sample size reassessment, to prevent the inflation of the Type-I error by using the weighted statistics proposed by Cui, Hung, Wang (1999). Keeping unchanged the targeted between-treatment difference, we used this statistics and followed the driving principle of considering that a sample size is optimal when the derivative of the power with respect to the sample size has reached some implicit value. Then we developed new strategies in order to express a) an optimally reassessed sample size as a function of the Z-statistic obtained at the first stage (at any interim analysis time, i.e. at any information fraction f (0<f<1)), b) an optimal information fraction fopt for the interim analysis, obtained as a function of (α, β), the Type-I and Type-II error rates. We adapted preliminary “conceptual” findings into a finally proposed “pragmatic” strategy. This pragmatic strategy was compared to two adaptive design methods of the literature (Cui, Hung, Wang, 1999; Denne, 2001) and to one adaptive method sometimes proposed, based on the current trend. We used the information fraction f = 0.5 and our optimal fopt ≈ 0.9 (found for usual values of α and β). When the interim analysis is performed at f=0.5, our method provides good results. When the interim analysis is performed with 90% of the data information, methods become roughly comparable. Our finding of an optimal time for reassessment is in fact useful for all methods. Results suggest that a sample size reassessment is more beneficial when performed close to the planned end of a trial, allowing a study with borderline interim results to be saved.
Fault-resilient and QoS centric dynamic network sensitive routing protocol for mobile-WSNs

The exponential rise in the demand of wireless communication has revitalized academia-industry to achieve more efficient networking solution. To meet these demands wireless sensor networks (WSNs) have always been the dominating solution, however static node and network characteristics confine its suitability for applications under dynamic topology. Strengthening WSN with fault-resilient route decision by exploiting dynamic network parameters such as current congestion probability, buffer availability, and packet injection rate can ensure reliable and quality of service (QoS) communication over WSNs under dynamic network topology. With this motivation, in this paper multiple network parameter-based fault-resilient and QoS centric dynamic network sensitive routing protocol (FQ-DNSRP) is developed. FQ-DNSRP exploits network parameters at the different layers of the IEEE 802.15. 4 protocol stack to derive a node rank matrix that helps in identifying best forwarding node for deadline sensitive and reliable data transmission. Simulation results revealed that the proposed FQ-DNSRP model exhibits satisfactory performance for real time data delivery over mobile-WSNs that can be significant for numerous applications, including IoT ecosystems.
Assessment of Anterior Alveolar Bone Dimensions in Adolescents and Adults with Class I Normal Occlusion

Aims: To investigate alveolar bone dimensions in the anterior segment of maxilla and mandible in 2 age group samples; adolescents and adults. Materials and Methods: Cephalometric radiographs of 60 adolescent (30 males and 30 females) and 60 adult subjects (30 males and 30 females) with Class I normal occlusion were included in this study. The anterior alveolar segment was assessed using several parameters that measure the thickness (labial and lingual) and height of alveolar bone surrounding upper and lower incisors. Upper and lower incisor inclination and palatomandibular plane (PMP) angle were also measured. Independent samples t– test and Pearson correlation coefficient were used for data analysis. Results: Sexual dimorphism was noticed in labial and palatal alveolar bone thickness of maxilla for both adolescent and adult subjects. Adult males also demonstrated significantly higher values for lower alveolar height and symphysis width than females. The comparison between 2 age groups revealed no significant difference for most variables and the most evident finding was the significantly higher values reported for upper and lower alveolar heights and symphysis width in adult males compared to adolescent males. The results of correlation analysis showed that upper incisor inclination has positive correlation with upper labial alveolar width and negative correlation with palatal alveolar width indicating that thinner palatal bone thickness is associated with more proclined upper incisors. Labial alveolar bone thickness at apical level of maxilla and mandible showed negative correlation with upper and lower alveolar heights in both age groups and with PMP angle in adults only. While, symphysis width showed positive correlation with the width of lingual alveolar bone and with alveolar heights. Conclusions: No significant differences were found between the 2 age groups, however in both adolescents and adults anterior alveolar dimensions showed sexual dimorphism and correlations with other cephalometric parameters.
Differentiability of Slope Limiters on Unstructured Grids

Despite emerging alternatives such as essentially nonoscillatory schemes, the use of slope limiters remains a standard means of eliminating oscillations in the second-order accurate solution of hyperbolic equations. However, slope limiters for unstructured grids are known to cause convergence problems. We demonstrate that fully-implicit solutions using Newton-Krylov methods are particularly affected. The root cause of this problem is shown to be the lack of differentiability of the limiting procedure. A modification to the limiting procedure is introduced and shown to improve convergence.
There is Hope for Japanese Learners of English: the Case of Telicity

This study looks into the acquisition of telicity by beginner and intermediate Japanese learners of English. In Japanese past predicates possess a neutral perfective reading, i.e. they can refer to either a past complete or an incomplete event, which makes them differ from equivalent predicates in English which largely entail event completion. We investigate whether Japanese learners of English learn to invalidate the neutral perfective reading in English given that it requires progress from a super-set to a sub-set interpretation for the simple past and given the absence of explicit instruction and/or negative evidence. The results show that beginners transfer their L1 Japanese telicity marking mechanism whereas intermediate level learners show progress toward the targetlike interpretation of telicity. We discuss whether intermediate L2 learners’ progression is due to their gained understanding of the determiner phrase (DP) morphology which influences the computation of telicity. We also speculate on how prolonged exposure to the target language may affect the representation of telicity by L2 learners.
The Challenges Of Adopting And Implementing Ifrs For Smes In Ghana: The Case Of Smes In The Kumasi Metropolis

The study examined the challenges of adopting and implementing International Financial Reporting Standard (IFRS) among SMES in the Kumasi Metropolis. Specifically, the study explored the extent of IFRS for SMEs adoption and implementation among SMEs and the challenges of IFRS for SMEs adoption and implementation among SMEs in the Kumasi Metropolis. Based on survey, the study employed Simple random sampling and purposive sampling techniques in selecting 119 respondents for the study. Simple percentages and frequency tables were employed for the data analysis through the help of statistical package for social sciences (SPSS). The study discovered that IFRS for SMEs adoption and implementation among SMEs is very low in the Metropolis, most SMEs prepare financial records using the erstwhile Ghana National Accounting Standard (GNAS). The study also revealed that inadequate requisite skills to successfully implement the IFRS for SMEs, lack of support from regulatory and professional bodies, the complex nature of the IFRS which bars most users from Researchjournali’s Journal of Accounting Vol. 5 | No. 4 October | 2017 3 www.researchjournali. com understanding statements prepared and the high implementation cost are the challenges being encountered by SMEs that have adopted the standard. The study recommends that the Government through the Ministry of Trade and Industry should collaborate with the Institute of Chartered Accountants-Ghana to give financial accounting education to SMEs owners who are mostly managers and their accounts clerks. The cost of the training should be shared among the owners of the SMEs and the Ministry of Trade and Industry.
Administration of Combined Methanolic Leaf Extracts of Vernonia amygdalina and Gongronema latifolium Enhanced Glut 2 Expression in the Pancreas and Downregulates Serum Caspase 3 Activity of Streptozotocin-Induced Diabetic Wistar Rats

Aim: The study evaluated the effects of the combined extracts of Vernonia amygdalina (VA) and Gongronema latifolium (GL) on pancreatic GLUT 2 expression and caspase 3 activity in streptozotocin (STZ, 45 mg/Kg)-induced diabetic rats. Study Design: Fifteen Albino rats were used for the study and were placed in 3 groups of 5 rats each: A - normal control, B – Diabetic control and C – experimental group. Place and Duration of Study: The study was carried out in the department of Anatomy, University of Calabar. Duration: 6 months. Methodology: Half of the diabetic rats were treated with VA+GL (400mg/kg, ratio 1:1, DE group) for 28 days, while the other half was untreated and served as diabetic control (DC). Normal control (NC) rats were untreated. After 28 days, the rats were sacrificed and their blood glucose, serum GLUT 2 and caspase 3 activity were measured. Histochemical evaluation of the pancreas was also carried out. Results: Blood glucose concentrations for the 3 groups were 60.31±7.28, 257.00±4.43, and 116.60±10.11 mg/dl for NC, DC and DE respectively. This represented a 4-fold increase in the DC compared with NC and a significant amelioration in the extract-treated DE group compared with DC group. Serum GLUT 2 concentrations were 70 ng/ml in NC, dropped to 8 ng/ml (p<0.05) in the DC and recovered to 20 ng/ml in DE (p<0.05). Serum caspase was 3.2 ng/ml for NC, increased to 8.5 ng/ml in DC (p<0.05) and reduced to 1.8 ng/ml in DE (p<0.05). The histology of the pancreas showed distorted, degenerated and shrunken β-cells mass in DC compared with NC and DE groups. The DE group showed clear signs of regeneration of the islet cells which was corroborated by positive Feulgen’s reaction compared with the DC group. Conclusion: The data suggests that the combined VA+GL extract has the potential to effectively reverse pancreatic damage in diabetes.
Water quality parameters and fisheries in central river region of the Gambia: Differences between wet and dry seasons

This research was aimed at studying the two seasonal changes in water quality of Central River Region (CRR) of The Gambia to influence fish assemblage. Physicochemical properties were measured in-situ with a portable YSI multiprobe water meter and fish sampling was done using a fishing net of 100 × 4 m. A total of 2,039 fishes, represented by sixteen species totaling to a biomass of 49, 236.3g were caught by seine netting. Laboratory analysis were also done for nitrite, nitrate, ammonia and phosphate in CRR using a spectrophotometer. The water variables were subjected to Principal Component Analysis (PCA) which showed a strong positive correlation between oxygen and pH, conductivity and TDS and negative correlation between oxygen and ammonia and nitrate (p ≤ 0.05). The research further showed that seasonal variation in environmental conditions have increased and are negatively influencing fish assemblage in CRR, determined from a three-decade time series of rainfall and atmospheric temperatures.
Assessment of The Lnc-CCAT1/miR-155a Regulatory Network in Acute Myeloid Leukemia

Colon cancer-associated transcript_1 (CCAT1) is a long noncoding RNA that maps to chromosome 8q24.21, it was first discovered to be upregulated in colorectal cancer. Recent studies have observed the CCAT1 overexpression in primary human solid cancers and cell lines as well as in AML, moreover, it repressed monocytic differentiation and promoted cell growth of HL-60 by sequestering tumor suppressive miR-155. However, the prognostic value of CCAT1/miR-155a pathway in acute myeloid Leukemia (AML) has not been investigated on clinical samples. In this study, the expression levels of CCAT1 and miR_155a was measured in 150 AML patients with standard and high-risk factors; CCAT1 and miR_155a were increased by 2.7 and 5.7 folds; respectively in AML compared to healthy controls. Furtherly, upregulation of both biomarkers was significantly associated with high risk AML. Collectively, these results suggest that CCAT1 and miR_155a can be considered as a diagnostic and prognostic biomarker in AML.
Fruiting bodies of Termitomyces intermedius collected in Iriomote – Ishigaki National Park, Ishigaki Island, Okinawa, Japan as sources of minerals

Samples of fruiting bodies of T. intermedius which were collected in Iriomote National Park, Ishigaki Island, Okinawa, Japan from June to July 2016 were air dried prior to elemental analysis. To determine the distribution of elements within the fruiting body, the stipe was partitioned into 3 parts namely bottom, middle, and upper. The pileus was also analyzed. Elemental analysis of the dried fruiting bodies was done using Thermo EDX System (Noran System 6, Ultra Dry, 10mm2 SDD crystal, 129eV resolution, NORVAR window, LN2-Free Type Detector) installed in Hitachi SU1510 scanning electron microscope. Nine elements namely N, O, Mg, Si, P, S, K, Fe and Ca were detected in the different parts of its fruiting bodies. The most abundant are O>Si>Fe>K>P>Ca>Mg>S>N in decreasing order of abundance. Most of the elements are concentrated in the stipe. All the elements except calcium are distributed within the fruiting body where most of the elements are concentrated at the bottom part of the stipe. Among the elements, calcium was only detected in the stipe and not in the pileus.
FACTORS INFLUENCING THE ADOPTION OF MOBILE TELEPHONY BY STUDENTS AT THE UNIVERSITY OF IBADAN, NIGERIA

This paper deployed Roger’s innovation adoption theory to explain the penetration of mobile technology in Nigeria’s premier higher educational institution, the University of Ibadan, using data collected from 370 students. Technological characteristics such as relative advantage, complexity, trialability and compatibility explained adoption. Age is negatively and significantly related to adoption, and enrollees for the PhD. programme appear to be less intensive adopters of mobile phones than those in the master's and bachelor's degree programmes. Except for interpersonal relationship, all psychological variables, perceived popularity, perceived need and mass media use have a significant relationship with adoption of the technology. This study is limited to respondents selected from one university using a questionnaire. Apart from providing policy information to the university which is currently implementing mobile learning systems, the results of the study may provide useful information to telecom companies on how to target student communities in designing and packaging their products and services.
Determinants of Financial Performance of Insurance Companies of USA and UK during Global Financial Crisis (2007-2016)

These findings will be helpful for insurance industries, government, policymakers and investors in taking decision and improving the performance.
Structural Organisation of Research Article Titles: A Comparative Study of Titles of Business, Gynaecology and Law

Since titles are gateways to the heart of research articles (RAs), their organisational structure should be regarded very crucial in appealing to the potential reader. This study aimed to investigate how titles of RAs are presented in three disciplines (Gynaecology/Obstetrics, Business, and Law). After a thorough study of 574 titles, the study revealed that Business titles were averagely longer than those in the other two disciplines. In terms of title style, it was revealed that the Single Unit Title was extensively used in Gynaecology/Obstetrics and Law, while the Compound Unit Title dominated the Business titles. Syntactically, Noun Phrases extremely dominated the Single Unit Titles across the three domains. Detailed examination of the NP modifications showed that nominal titles which were both Pre and Post-modified were highly frequent in all the disciplines, which contrasts what is in the literature. The study also identified the Prepositional Phrase as the commonest structure used in post-modifying the nominal structures than using non-finite clauses in all the disciplines. Again, colon was the most predominant punctuation mark used in partitioning the Compound Unit Titles across the three disciplines, with Law recording the highest followed by Gynaecology/Obstetrics and Business. Lastly, the data exhibited high frequency of Domain-Specific words in the titles more than Research-Based words across the disciplines. This study provides useful information on the nature of effective RA titles to novice writers and advanced authors. It also informs the teaching of academic writing skills.
