Evaluation of Concept Importance in Concept Maps Mined from Lecture Notes - Computer Vs Human

Concept maps are commonly used tools for organising and representing knowledge in order to assist meaningful learning. Although the process of constructing concept maps improves learnersâ cognitive structures, novice students typically need substantial assistance from experts. Alternatively, expert-constructed maps may be given to students, which increase the workload of academic staff. To overcome this issue, automated concept map extraction has been introduced. One of the key limitations is the lack of an evaluation framework to measure the quality of machine-extracted concept maps. At present, researchers in this area utilise human expertsâ judgement or expert-constructed maps as the gold standard to measure the relevancy of extracted knowledge. However, in the educational context, particularly in course materials, the majority of knowledge presented is relevant to the learner, resulting excess of information for knowledge organisation. Therefore, this paper introduces a novel machine-based approach which studies the relative importance of knowledge and organise knowledge hierarchically according to their importance. We compare machineâs prediction with human judgment based on expertsâ knowledge and perception. Our ranking model utilise linguistic and structural features such as nouns, degree of co-occurrence and proximity. The results show that the machineâs predication positively correlates with human (rs~1) for well-fitted courses.
Arabidopsis VQ MOTIF-CONTAINING PROTEIN29 Represses Seedling Deetiolation by Interacting with PHYTOCHROME-INTERACTING FACTOR11[C][W][OPEN]

A transcriptional regulator interacts with the transcription factor PIF1 to modulate hypocotyl cell growth in response to light. Seedling deetiolation, a critical process in early plant development, is regulated by an intricate transcriptional network. Here, we identified VQ MOTIF-CONTAINING PROTEIN29 (VQ29) as a novel regulator of the photomorphogenic response in Arabidopsis (Arabidopsis thaliana). We showed that 29 of the 34 VQ proteins present in Arabidopsis exhibit transcriptional activity in plant cells and that mutations in the VQ motif affect the transcriptional activity of VQ29. We then functionally characterized VQ29 and showed that the hypocotyl growth of plants overexpressing VQ29 is hyposensitive to far-red and low-intensity white light, whereas a vq29 loss-of-function mutant exhibits decreased hypocotyl elongation under a low intensity of far-red or white light. Consistent with this, VQ29 expression is repressed by light in a phytochrome-dependent manner. Intriguingly, our yeast (Saccharomyces cerevisiae) two-hybrid, bimolecular fluorescence complementation, and coimmunoprecipitation assays showed that VQ29 physically interacts with PHYTOCHROME-INTERACTING FACTOR1 (PIF1). We then showed that VQ29 and PIF1 directly bind to the promoter of a cell elongation-related gene, XYLOGLUCAN ENDOTRANSGLYCOSYLASE7, and coactivate its expression. Furthermore, the vq29 pif1 double mutant has shorter hypocotyls than either of the corresponding single mutants. Therefore, our study reveals that VQ29 is a negative transcriptional regulator of light-mediated inhibition of hypocotyl elongation that likely promotes the transcriptional activity of PIF1 during early seedling development.
Finger-Print Characteristics

The study of the various systems of personal identification has for many years occupied the attention of anthropologists and those upon whom devolves the duty of searching for the antecedents of suspects of the criminal classes; but it is only within comparatively recent times that the value of digital impressions as an effective and irrefutable means of establishing identity has been definitely recognized. In 1888, Sir Francis Galton, the eminent anthropologist, commenced his investigations into the subject of finger-prints, being at first exclusively interested in its bearings on questions of hereditary and racial distinctions. He was considerably handicapped by the lack of a sufficiently varied and cosmopolitan series of impressions, and although he obtained the necessary data to establish successfully the probalility of transmission of patterns by descent, he was unable to trace any correlation between particular types and ethnological variations. He subsequently directed his investigations into practical channels and established the Finger-Print System, which during the last few years has been adopted by the police of almost every country as the simplest and most certain means of identification of criminals. It will be essential to give a short description of the system, avoiding as much as possible all technicalities. Finger-prints may be described briefly as unerring and unvarying sign-manuals which admit of being so classified as to afford any easy clue to the discovery of the name and also the record of a person who withholds or falsifies it. Impressions of the top bulbs of the ten fingers and thumbs are taken separately with ink, and each is classified according to the trend of the minute ridges which are easily visible on the skin, and whose functions, physiologists have never yet been able to determine with any degree of certainty. These ridges must not be confused with those creases which mark the flexion of the skin in the palms and phalanges, and upon whose tracings the so-called science of palmistry is reputed to be founded. Galton devised three distinct types of ridges, the arch, the loop and the zwhorl, any of which it is pefectly simple to recognize with a little practice. The pattern is an Arch "when the ridges in the centre run from one side to the other without assuming a backward
RESOURCE‐ASSOCIATED POPULATION SUBDIVISION IN A SYMBIOTIC CORAL‐REEF SHRIMP

The importance of sympatric speciation remains controversial. An empirical observation frequently offered in its support is the occurrence of sister taxa living in sympatry but using different resources. To examine the possibility of sympatric differentiation in producing such cases, I measured genetic, behavioral, and demographic differentiation between populations of the tropical sponge‐dwelling shrimp Synalpheus brooksi occupying two alternate host species on three reefs in Caribbean Panama. This species belongs to an apparently monophyletic group of ≥ 30 species of mostly obligate, host‐specific sponge‐dwellers, many of which occur in sympatry. Demographic data demonstrated the potential for disruptive selection imposed by the two host species: shrimp demes from the sponge Agelas clathrodes were consistently denser, poorer in mature females, more heavily parasitized by branchial bopyrid isopods, and less parasitized by thoracic isopods, than conspecific shrimp from the sponge Spheciospongia vesparium. Laboratory assays demonstrated divergence in host preference: shrimp on all three reefs tended to choose their native sponge species more often than did conspecific shrimp from the other host. Because S. brooksi mates within the host, this habitat selection should foster assortative mating by host species. A hierarchical survey of protein‐electrophoretic variation also supported host‐mediated divergence, revealing the following: (1) shrimp from the two hosts are conspecific, as evidenced by absence of fixed allelic differences at any of nine allozyme loci scored; (2) strong genetic subdivision among populations of this philopatric shrimp on reefs separated by 1–3 km; and (3) significant host‐associated genetic differentiation within two of the three reefs. Finally, intersexual aggression (a proxy for mating incompatibility) between shrimp from different host species was significantly elevated on the one reef where host‐associated genetic differences were strongest, demonstrating concordance between genetic and behavioral estimates of divergence. Adjacent reefs appear to be semi‐independent sites of host‐associated differentiation, as evidenced by differences in the degree of host‐associated behavioral and genetic differentiation, and in the specific loci involved, on different reefs. In philopatric organisms with highly subdivided populations, such as S. brooksi, resource‐associated differentiation can occur independently in different populations, thus providing multiple “experiments” in differentiation and resulting in a mosaic pattern of polymorphism as reflected by neutral genetic markers. Several freshwater fishes, an amphipod, and a snail similarly show independent but remarkably convergent patterns of resource‐associated divergence in different conspecific populations, often in the absence of obvious spatial barriers. In each case, substantial differentiation has occurred in the face of continuing gene flow.
The Effects of Problem Structure and Team Diversity on Brainstorming Effectiveness

Since Osborn's Applied Imagination book in 1953 (Osborn, A. F. 1953. Applied Imagination: Principles and Procedures of Creative Thinking. Charles Scribner's Sons, New York), the effectiveness of brainstorming has been widely debated. While some researchers and practitioners consider it the standard idea generation and problem-solving method in organizations, part of the social science literature has argued in favor of nominal groups, i.e., the same number of individuals generating solutions in isolation. In this paper, we revisit this debate, and we explore the implications that the underlying problem structure and the team diversity have on the quality of the best solution as obtained by the different group configurations. We build on the normative search literature of new product development, and we show that no group configuration dominates. Therefore, nominal groups perform better in specialized problems, even when the factors that affect the solution quality exhibit complex interactions (problem complexity). In cross-functional problems, the brainstorming group exploits the competence diversity of its participants to attain better solutions. However, their advantage vanishes for extremely complex problems.

Exploring High Performance Processing Through Reconfigurable Computing Systems

The reconfigurable computing is anticipated to block-up the breach among extremely inflexible but high performance Application Specific Integrated Circuits (ASICs) based technology and most flexible but slow speed General Purpose Processors (GPPs) based technology. The main inspiration behind the reconfigurable computing technology is to tightly couple the performance and flexibility aspects of both of these existing technologies into one platform. This kind of tight coupling of both technologies requires high advancements in the area of computing science and engineering. This research paper presents a comprehensive work about the existing reconfigurable computing systems. It highlights the hardware and software level issues being investigated into the domain of reconfigurable computing. It also highlights the emerging requirements being pointed out for further enhancement of the existing computing technology. A large number of emerging software and hardware level aspects have been investigated to cope up with the existing technology barrier. Special considerations are required in this domain for high performance computing systems to boost up the software and hardware development of such kind of advanced computing platforms to support the next generation high speed dataintensive computing demands.
Scheduled meal accelerates entrainment to a 6‐h phase advance by shifting central and peripheral oscillations in rats

Travelling across several time zones requires a fast adjustment of the circadian system and the differential adjustment speeds of organs and systems results in what is commonly referred as jet lag. During this transitory state of circadian disruption, individuals feel discomfort, appetite loss, fatigue, disturbed sleep and deficient performance of multiple tasks. We have demonstrated that after a 6‐h phase advance of the light–dark cycle (LD) scheduled food in phase with the new night onset can speed up re‐entrainment. In this study, we explored the possible mechanisms underlying the fast re‐entrainment due to the feeding schedule. We focused on first‐ and second‐order structures that provide metabolic information to the suprachiasmatic nucleus (SCN). We compared (i) control rats without change in LD cycle; (ii) rats exposed to a 6‐h phase advance of the LD cycle with food ad libitum; and (iii) rats exposed to the 6‐h phase advance combined with food access in phase with the new night. We found an immediate synchronizing effect of food on stomach distention and on c‐Fos expression in the nucleus of the solitary tract, arcuate nucleus of the hypothalamus, dorsomedial hypothalamic nucleus and paraventricular nucleus. These observations indicate that in a model of jet lag, scheduled feeding can favour an immediate shift in first‐ and second‐order relays to the SCN and that by keeping feeding schedules coupled to the new night, a fast re‐entrainment may be achieved by shifting peripheral and extra‐SCN oscillations.
Securing Smart Grid In-Network Aggregation through False Data Detection

Existing prevention-based secure in-network data aggregation schemes for the smart grids cannot effectively detect accidental errors and falsified data injected by malfunctioning or compromised meters. In this work, we develop a light-weight anomaly detector based on kernel density estimator to locate the smart meter from which the falsified data is injected. To reduce the overhead at the collector, we design a dynamic grouping scheme, which divides meters into multiple interconnected groups and distributes the verification and detection load among the root of the groups. To enable outlier detection at the root of the groups, we also design a novel data re-encryption scheme based on bilinear mapping so that data previously encrypted using the aggregation key is transformed in a form that can be recovered by the outlier detectors using a temporary re-encryption key. Therefore, our proposed detection scheme is compatible with existing innetwork aggregation approaches based on additive homomorphic encryption. We analyze the security and efficiency of our scheme in terms of storage, computation and communication overhead, and evaluate the performance of our outlier detector with experiments using real-world smart meter consumption data. The results show that the performance of the light-weight detector yield high precision and recall. Received on 25 November 2016; accepted on 14 January 2017; published on 31 January 2017
1,5-Anhydro-D-glucitol Evaluates Daily Glycemic Excursions in Well-Controlled NIDDM

OBJECTIVE To evaluate the usefulness of plasma 1,5-anhydro-D-glucitol (1,5-AG) as a possible marker for daily glycemic excursion, we measured plasma 1,5-AG, HbA1c, fasting plasma glucose (FPG) level, and daily excursion of glycemia, from which the M-value (after Schlichtkrull) was calculated as an index of daily glycemic excursion. RESEARCH DESIGN AND METHODS The subjects were 76 patients with well-controlled non-insulin-dependent diabetes mellitus (NIDDM) treated with diet therapy only (diet, n = 17), oral hypoglycemic agents (OHA, n = 28), conventional insulin therapy (CIT, n = 16), or multiple insulin injection therapy (MIT, n = 15). RESULTS HbA1c values were similar among all the groups (diet, 6.9 ± 0.6; OHA, 7.2 ± 0.5; CIT, 7.1 ± 0.6; MIT, 7.2 ± 0.5%). The MIT group showed a significantly higher 1,5-AG concentration (11.5 ± 5.3 μg/ml), a significantly lower M-value (9.2 ± 5.2), and little risk of hypoglycemia (< 4 mmol/l) and hyperglycemia (> 10 mmol/l) (1.3 ± 1.1 times/24 h) compared with the CIT group (6.9 ± 3.3μg/ml, 15.7 ± 8.9, 2.2 ± 1.6 times/24 h, respectively). Insulin doses (22.4 ± 4.5 vs. 22.0 ± 8.9 U/day), FPG (6.6 ± 2.2 vs. 7.4 ± 2.4 mmol/l), and HbA1c concentrations were not significantly different between the CIT and MIT groups. M-values significantly correlated with 1,5-AG concentrations (r = 0.414, P < 0.05), but not with HbA1c concentrations. CONCLUSIONS The findings suggest that the plasma 1,5-AG concentration can be a useful index of the daily excursion of blood glucose, especially in patients with well-controlled NIDDM.
Geometric Power Control for Time-Switching Energy-Harvesting Two-User Interference Channel

This paper studies the optimization of power control for the two-user interference channel in which the terminals are time-switched between the communication and energy-harvesting phases. The objective is to maximize the sum rate, subject to the minimum data and harvested energy constraints at the receivers, assuming a fixed time-switching coefficient. Our key contribution is a geometric approach that analyzes the feasible region governed by the constraints, which gives rise to the optimal power control solution. We assume that perfect channel state information is available at both transmitters to determine the solution.
Validation of the Intelligent Cognitive Assessment System (ICAS) for stroke survivors

Primary objective: To investigate the internal consistency, test–re-test reliability of an Intelligent Cognitive Assessment System (ICAS) and its optimal cut-off score for stroke patients with or without cognitive impairment. Method: A prospective cohort study design was adopted. Sixty-six post-stroke patients of aged 60 or above were recruited. They were screened by the Chinese version of Mini Mental State Examination (MMSE-CV) and assessed by the Intelligent Cognitive Assessment System (ICAS) consisting of 65 testing items which could be presented at a level according to stroke patient's response. It was administered to examine the internal consistency and test–re-test reliability (by repeating within a 7-day interval). The optimal cut-off score to screen stroke patients having cognitive impairment was determined by the receiver operating characteristics (ROC) curve. Results: The internal consistency of the ICAS (Cronbach's α = 0.878) and its test–re-test reliability (ρ = 0.789; p < 0.001) were demonstrated. The cut-off score for the ICAS to determine cognitive impairment was found to be 3.02, with a sensitivity of 80.5% and specificity of 96%. Conclusion: Preliminary results suggested that ICAS was a valid and reliable cognitive screening tool for stroke survivors. The ICAS can be further developed by studying its norms for stroke patients. It is also programmable for potential application to different countries by changing ICAS to other language versions and including other culturally relevant content.
SIMGraph: Simplifying Contig Graph to Improve de Novo Genome Assembly Using Next-generation Sequencing Data

De novo genome assembly is always fragmented. Assembly fragmentation is more serious using the popular next generation sequencing (NGS) data because NGS sequences are shorter than the traditional Sanger sequences. As the data throughput of NGS is high, the fragmentations in assemblies are usually not the result of missing data. On the contrary, the assembled sequences, called contigs, are often connected to more than one other contigs in a complicated manner, leading to the fragmentations. False connections in such complicated connections between contigs, named a contig graph, are inevitable because of repeats and sequencing/assembly errors. Simplifying a contig graph by removing false connections directly improves genome assembly. In this work, we have developed a tool, SIMGraph, to resolve ambiguous connections between contigs using NGS data. Applying SIMGraph to the assembly of a fungus and a fish genome, we resolved 27.6% and 60.3% ambiguous contig connections, respectively. These results can reduce the experimental efforts in resolving contig connections. Keywords—contig graph, NGS, de novo assembly, scaffold
Profit, Planet and People in Supply Chain: Grand Challenges and Future Opportunities

Recent pressure from governments and customers on supply chain organizations to consider environmental and social issues has increased dramatically. The challenge ahead for supply chain managers is how to grow business profit while protecting the planet and respecting people’s rights. The significance of this issue motivates researchers in the fields of “sustainability” and “supply chain” to further integrate these concepts. To identify affected areas, and how sustainability influences them, this research has employed a literature survey of related papers published between 2012 and 2016 within 16 A* indexed journals that are relevant to Information and Computing Science, Transportation/ Freight Services and Manufacturing Engineering. Findings show that sustainable supply chain network structure, impact factors, relationship integration and performance evaluation are the main research topics in these streams. The role of decision-making tools within each discipline, the key methodologies and techniques are discussed. Generally speaking, primary challenges in the sustainable supply chain domain devolve from use of inadequate decision-making tools and inappropriate information systems. The holistic picture presented in this paper is important for helping scholars, system developers, and supply chain analysts to become more aware of current grand challenges and future research opportunities within this field.
Complete 3D-Reduced Surface Field Superjunction Lateral Double-Diffused MOSFET Breaking Silicon Limit

A new superjunction lateral double-diffused MOS with the semi-insulating poly silicon (SIPOS SJ-LDMOS) has been proposed in this letter, for the first time, with the complete three-dimensional reduced surface field (3D-RESURF). The SIPOS SJ-LDMOS along the three dimensions are subject to the electric field modulation, which achieves the complete 3D-RESURF effect. The simulated breakdown voltage (BV) for the unit length of the drift region is improved to 19.4 V/μm. The drift region with the high concentration compared with the conventional LDMOS can be depleted completely in the OFF-state to obtain the high BV. Moreover, the majority carrier accumulation can be formed to further decrease RON,sp (specific on resistance) during the ON-state operation. Three effects have been combined to SIPOS SJ-LDMOS for the superjunction ideal, electric field modulation and the majority carrier accumulation by SIPOS. The tradeoff between the BV and RON,sp has been improved to break through the silicon limit. The results show that the experimental RON,sp of SIPOS SJ-LDMOS is 18 mQ · cm2 with the tested BV of 376 V, which is less than that of 31.1 mQ · cm2 for the N-buffer SJ-LDMOS with the simulated BV of 287 V, and far less than 71.8 mQ · cm2 for the conventional LDMOS with the simulated BV of 254 V for the same drift region length of 20 μm.
