Effects of using problem-solving guide and explanatory support in program visualization tool on reducing students’ misconceptions in learning data structure concepts

The tendency of novice programmers to hold misconceptions when learning data structures is one of the challenges that novice programmers face in computer science education. Holding misconceptions can result in students’ demotivation and high failure rates in learning the subject. This article presents the findings of an experimental study that was conducted to determine whether using the CeliotM Program visualization tool could help students learn CS 122 (data structures) at the College of Informatics and Virtual Education of the University of Dodoma with fewer misconceptions. The design chosen was a single factor between the experiment designs, with the number of errors committed by the students when writing programs as a dependent variable. The experimental group received instruction using the teaching technique employed by CeliotM, while the control group received instruction using the conventional lecture method. Results show that the use of CeliotM significantly reduced students misconceptions compared to the conventional lecture method. The study's important findings suggest that employing the CeliotM framework can help students understand data structures more effectively by minimizing their misconceptions and hence enhance their programming competencies.
Investigation of the Morpho-Anatomical and Epidermal Properties of Commelina erecta L.

In traditional medicine, Commelina erecta L. has been used as antiviral, for the treatment of hemorrhages, skin rashes and sores, and for the treatment of infections. It is also used as a wild edible plant in salads, preserves or decorating the dishes. Hence, the objective of this paper was to investigate the morpho-anatomical and epidermal properties of Commelina erecta L of Commelinaceae using appropriate standard methods. Results revealed C. erecta as a Broadleaf and vivacious branching up to 20 to 55 cm in length as it trails and roots at nodes, having leaves which are elliptical, oval to lanceolate and sub sessile about 2.5 ± 0.5 cm long and 1.5 ± 0.5 cm wide; the leaf sheath is closed and united at base. The stomata are anomocytic, tetracytic and paracytic stomata with pentagonal to heptagonal epidermal cells and trichomes (piloses) including glandular trichomes which are amphistomatic. Anatomical sections showcased root pith, vascular bundles scattered and concentrated towards the ground tissues. These information would assist for further delimitation of the species.
Towards Secure and Fast Mapping of Genomic Sequences on Public Clouds

The rapid advances in genomic technologies have led to the exponential growth of genomic data. On one hand, clinics and research institutions need to consider the security issue since the data privacy needs to be protected. On the other hand, they look for the means to improve the scalability and performance of genomic applications to be able to handle large amount of data as well as heavy computations. While existing approaches have to sacrifice one for the other, we aim at achieving all the three goals above. In this paper, we design an entire secure framework for genomic data processing on public clouds. Based on this framework, we propose a 3-encryption-scheme model for genomic sequence mapping (3EGSM), an important phase of genomic computation. The model protects not only genomic sequences but also the intermediate and final computation results when processing on public clouds. We evaluate the proposed framework through intensive experiments using real genomic data. The experimental results show that the proposed framework reduces the sequential mapping time by up to 75% compared to a baseline approach that considers only the security issue. The experimental results also show that the framework achieves high speedup when performing parallel processing.

In this paper, a semantic image content analysis framework based on Fuzzy Petri Net is presented. Knowledge scheme is used to define more general and complex semantic concepts and their relations in the context of the examined outdoor domain. A formal description of hierarchical and spatial relationships among concepts from the outdoor image domain is described. The automatic image annotation procedure based on fuzzy recognition algorithm, that maps high-level semantics to image, is presented.
Enamel Hypoplasia Management With Direct Composite Resin

Introduction: Disturbances during teeth growth and development may lead to dental abnormalities. Disruption in the process of formation of the enamel matrix may result in a surface defect known as enamel hypoplasia. Purpose: This case report aimed to show a technique of direct composite resin for esthetic resolution in anterior teeth with enamel hypoplasia. Case presentation: A 20-year-old male patient presented at the YARSI Dental Hospital (Jakarta) with a complaint of chalky white spots on the maxillary anterior teeth. The clinical examination showed wet white spots on the labial surfaces of 13, 21, and 23 (FDI), also caries on the labial and mesial surfaces of 12, 11, and 22. The treatment plan were composite resin direct veneers on After 5 months follow-up, evaluation of patients’s appearance showed that the affected teeth are maintained in good condition. Conclusion: Clinical success in the management of enamel hypoplasia depends on the severity of the lesion, the diagnosis, and the determination of a treatment plan.
Role for NudC, a dynein-associated nuclear movement protein, in mitosis and cytokinesis

NudC, a nuclear movement protein that associates with dynein, was originally cloned as a mitogen-inducible early growth response gene. NudC forms a biochemical complex with components of the dynein/dynactin complex and is suggested to play a role in translocation of nuclei in proliferating neuronal progenitors as well as in migrating neurons in culture. Here, we show that NudC plays multiple roles in mitosis and cytokinesis in cultured mammalian cells. Altering NudC levels by either small interfering RNA-mediated gene silencing or adenovirus-mediated overexpression resulted in multinucleated cells and cells with persistent intercellular connections and disorganized midzone and midbody matrix. These phenotypes suggest a failure in cytokinesis in NudC altered cells. Further, a key mitotic enzyme, polo-like kinase, is mislocalized from the centrosomes and the midbody in NudC altered cells. Gene silencing of nud-1, the Caenorhabditis elegans ortholog of NudC, led to a loss of midzone microtubules and the rapid regression of the cleavage furrow, which resulted in one-celled embryos containing two nuclei. The loss of midzone microtubule organization owing to silencing of the NudC/nud-1 gene in two systems, coupled with the loss of Plk1 from mitotic structures in mammalian cells, provide clues to the cytokinesis defect and the multinucleation phenotype. Our findings suggest that NudC functions in mitosis and cytokinesis, in part by regulating microtubule organization at the midzone and midbody.
Tradeoff between Stability and Maneuverability during Whole-Body Movements

Background Understanding how stability and/or maneuverability affects motor control strategies can provide insight on moving about safely in an unpredictable world. Stability in human movement has been well-studied while maneuverability has not. Further, a tradeoff between stability and maneuverability during movement seems apparent, yet has not been quantified. We proposed that greater maneuverability, the ability to rapidly and purposefully change movement direction and speed, is beneficial in uncertain environments. We also hypothesized that gaining maneuverability comes at the expense of stability and perhaps also corresponds with decreased muscle coactivation. Materials and Methods We used a goal-directed forward lean movement task that integrated both stability and maneuverability. Subjects (n = 11) used their center of pressure to control a cursor on a computer monitor to reach a target. We added task uncertainty by shifting the target anterior-posterior position mid-movement. We used a balance board with a narrow beam that reduced the base of support in the medio-lateral direction and defined stability as the probability that subjects could keep the balance board level during the task. Results During the uncertainty condition, subjects were able to change direction of their anterior-posterior center of pressure more rapidly, indicating that subjects were more maneuverable. Furthermore, medio-lateral center of pressure excursions also approached the edges of the beam and reduced stability margins, implying that subjects were less stable (i.e. less able to keep the board level). On the narrow beam board, subjects increased muscle coactivation of lateral muscle pairs and had greater muscle activity in the left leg. However, there were no statistically significant differences in muscle activity amplitudes or coactivation with uncertainty. Conclusions/Significance These results demonstrate that there is a tradeoff between stability and maneuverability during a goal-directed whole-body movement. Tasks with added uncertainty could help individuals learn to be more maneuverable yet sufficiently stable.
AMES-Cloud: A Framework of Preservation, Fetching and Decisive Video Streaming Over Cloud Computing

The exponential increasing traffic demands of mobile streaming services over a network have been unpleasant the wireless link capability cannot keep up with the growing traffic load. There is some space between link capability and traffic demand with time varying link condition which gives results in poor quality of streaming services such as constant interruption and long buffering delays. The AMES-Cloud proposes a new video streaming methods which is UserAdaptive Mobile Video Streaming (AMoV) and UserBehavior Oriented Video Pre-fetching (UBoP). The AMoV and UBoP create a private mediator for efficient video streaming distribution process. The private mediator adjust the streaming flow and reduces the traffic using scalable video coding technique ( SVC ) which shows the social interaction among each user. The video quality of streaming is based on the feedback of link quality. This shows the effectively streaming and sharing service over a network. The efficient background pre-fetching is also done which is based on user resolution and bandwidth. It provides advance and excellence service of video streaming while using the networking and computing assets resourcefully.
Increased Expression and Activity of RhoA Are Associated With Increased DNA Synthesis and Reduced p27Kip1 Expression in the Vasculature of Hypertensive Rats

Abstract— We have previously shown that the function of the small G protein Rho is required for vascular smooth muscle cell proliferation and migration. We hypothesized that changes in Rho or Rho signaling might contribute to enhanced vascular proliferative responses associated with hypertension. Western blot analysis revealed that total RhoA expression was ≈2-fold higher in aortas, tail arteries, and aortic smooth muscle cells (ASMCs) obtained from adult male spontaneously hypertensive rats (SHR) compared with those from Wistar Kyoto rats (WKY). An increase in active GTP-bound RhoA was detected in aortic homogenates by affinity precipitation with the RhoA effector rhotekin and by examining RhoA-[35S]GTP&ggr;S binding. RhoA protein and activity were also increased in vessels from rats treated with N-nitro-l-arginine methyl ester to increase blood pressure. Thrombin-stimulated RhoA activation was also significantly greater in ASMCs from SHR. As a functional correlate of these changes in Rho signaling, thrombin-stimulated DNA synthesis was enhanced in tail arteries and ASMCs from SHR. Expression of the cyclin-dependent kinase inhibitor p27Kip1 was decreased by two thirds in SHR, and this decrease was mimicked in ASMCs by expression of a constitutively active (GTPase-deficient) mutant of RhoA. Wortmannin (10 nmol/L) fully inhibited the decrease in p27Kip1 induced by RhoA, and a membrane-targeted catalytic subunit of phosphatidylinositol-3 kinase (PI3K [p110CAAX]) decreased p27Kip1 expression, suggesting that RhoA signals through PI3K. These data provide evidence that RhoA brings about changes in DNA synthesis through reduced expression of p27Kip1, mediated in part via PI3K, and suggest that increases in RhoA expression and activity contribute to the enhanced vascular responsiveness observed in hypertension.
OWL Instance Data Evaluation (Statement of Interest)

As more applications are depending on semantic web data from diverse sources, semantic web data evaluation is becoming more critical. While language validators and general reasoners can help, these typically focus on syntax and logical consistency. Many applications need additional support for finding possible issues (as well as provable mistakes). We are investigating methods and environments that provide computational support for identifying possible problems with instance data. We report on a line of work focusing on evaluation of provable and possible problems with OWL instance data and provide some discussion motivated by our first application setting validating large amounts of diverse explanation data.
Wireless Sensor Networks and Beyond: A Case Study on Transport and Logistics

Wireless Sensor Networks provide opportunities even outside their usual application domain of environmental monitoring. In this paper we present a case study on the use of Wireless Sensor Networks for the control and management of transport and logistics processes. In this study nodes will track all activities, and check for errors that might occur in the process of handling and distributing goods. The nodes will be programmed to warn when errors occur, and keep an activity record of the entire process. An overview of the current situation, and the errors that occur therein, is given. A system architecture is described that can solve or reduce the current problems by incorporating a Wireless Sensor Network in the process.
The head and neck muscles of the Philippine colugo (Dermoptera: Cynocephalus volans), with a comparison to tree‐shrews, primates, and other mammals

The colugos, or flying lemurs (Dermoptera), are arboreal gliding mammals that are commonly grouped with tree‐shrews (Scandentia) and Primates in the superorder Euarchonta. However, little is known about the head and neck muscles of these gliding mammals. This raises difficulties for the discussion of not only the functional morphology and evolution of colugos, but also the origin, evolution, functional morphology, and phylogenetic relationships of the Euarchonta as a whole, and thus also of our own clade, the Primates. In this work, I describe the head and neck muscles of the colugo Cynocephalus volans, and compare these muscles with those of other mammals, either dissected by me or described in the literature. My observations and comparisons indicate that, with respect to the number of muscles, the plesiomorphic condition for euarchontans as well as for primates is more similar to that found in extant tree‐shrews than in extant colugos. This is because various muscles that were probably plesiomorphically present in the euarchontan and primate clades, as, e.g., the stylohyoideus, mandibulo‐auricularis, cleido‐occipitalis, omohyoideus, and sternohyoideus, are not present as independent elements in extant colugos. These observations and comparisons also indicate that various laryngeal and facial muscles that are present in modern humans were absent in the last common ancestor of extant primates. J.

Obtention, characterization and cytotoxicity of fixed oils from Elaeocarpus serratus: a remarkable vegetable oil

The specie Elaeocarpus serratus belonging to the Elaeocarpaceae family is popularly known as Ceylon Olive and used medicinally for the treatment of bacterial and fungal infections. The fruits contain tannins and fatty acids in fixed oils (FO). The specie adapts well to the conditions of the soil and climate of Brazil and, due to the good productivity of fruits that the plant presents, it shows potential in the production of FO. Despite its uses, there are no studies that provide more details on the characterization and obtaining of oils from this species. The objective of this study was aimed to characterize the obtention and properties of the oil seed to verify the yield and the potential use. The FOs were obtained by the Soxhlet extraction method and analyzed through the parameters refractive, acidity and saponification indexes. From the FOs obtained, the seeds resulted in the highest yield (1.71%), followed by pericarps with seeds (1.01%) and pericarps (0.49%). The FOs were submitted to the lethality test of Artemia saline as a predictor of cytotoxicity, obtaining percentages of lethality of 76% for seed oil. The high cytotoxicity shown by the OFs corroborates with the antimicrobial and antifungal uses of the species and the indexes tested showed that the oil obtained from the seed demonstrates potential application in products with industrial, cosmetic and pharmaceutical interests.
On The Solution Sets Of Semicontinuous Quantum Stochastic Differential Inclusions ∗

The aim of this paper is to provide a unified treatment of the existence of solution of both upper and lower semicontinuous quantum stochastic differential inclusions. The quantum stochastic differential inclusion is driven by operatorvalued stochastic processes lying in certain metrizable locally convex space. The unification of solution sets to these two discontinuous non-commutative stochastic differential inclusions is established via the existence of directionally continuous selections.
LIGAND‐BINDING IN PORPHYRIN SYSTEMS *

When hemoglobin is denatured with caustic alkali and then reduced, a distinct pigment called globin hemochromogen is formed in which the fifth and sixth coordination positions of the heme iron are bonded to exposed nitrogens of the denatured proteins amino acid side chains. ' This pigment has a sharp two-band absorption spectrum in the visible region and a strong Soret absorption band. The two absorption bands in the visible region are termed the a band (558 mp) and the /3 band (528 mp) of which the a band is more intense. Full development of this pigment is slow, so that for routine spectrophotometry a more rapid analysis has been developed whereby the nitrogenous ligands are supplied in excess by the addition of pyridine. The resulting pyridine hemochromogen has essentially the same spectral properties as globin hernochromogen and gives full color development within a few seconds. In spite of the apparent simplicity of the method, a review of the pyridine hemochromogen literature revealed a considerable disparity in reported absorption band positions and in their extinction coefficients.2-'o Therefore, we have made a careful analysis of the titration of heme with pyridine both in regard to the stoichiometry of the reaction and in regard to parameters responsible for changes in the absorption spectrum of pyridine hemochromogen. Analogous studies on imidazole hemochromogen and ammonia hemochromogen were extended to reactions of these nitrogenous ligands with hematin.I2 The effect of ethanol and caffeine on heme, hematin,I3 protoporphyrin and hematoporphyrin have also been investigated.
The Potential Role of the Extracellular Matrix Glycoprotein Reelin in Glioblastoma Biology

Glioblastoma, the most common and lethal primary adult brain tumor, cannot be successfully removed surgically due to its highly invasive nature. Therapeutically, approaches must be aimed at a systemic brain disease and not merely at a tumor located within the brain, unless a successful containment strategy can be found. Reelin, an extracellular matrix glycoprotein, plays an important role in neuronal migration and serves here as a natural stop signal. Interestingly, the expression of reelin is negatively associated with tumor grade and, within glioblastoma, correlates with increased overall survival. To further elucidate a potential biological reason for these findings, we looked at the cellular behavior of glioblastoma cell lines grown on a pure fibronectin matrix or a matrix with reelin inserts. While reelin had no significant effects on cellular metabolism, proliferation, or resistance to chemotherapeutic agents, it did significantly affect the cells’ interaction with fibronectin. Both matrix attachment and detachment were modulated by reelin, and thus, the invasion and motility of cells interacting with a reelin-containing matrix were altered. The data presented in this work strongly suggest that reelin might be a potential modulator of underlying molecular mechanisms that contribute to glioblastoma invasion.
Low-order Kalman filters for channel estimation

This paper addresses the design of low-order Kalman filters to estimate radio channels with Rayleigh fading. Rayleigh fading cannot be perfectly modelled with any finite order auto-regressive (AR) process. Previously, only first and second order Kalman filters were used for channel estimation since higher order Kalman filters were found to not significantly improve accuracy. This is due to mismatches in the statistics of the AR models of the Kalman filters and the true Rayleigh fading. In this paper, the coefficients of the AR models for the Kalman filter are calculated by solving for the minimum square error solutions of an over-determined linear systems. The AR models generated have statistics closely matching the Rayleigh fading process. The Kalman filter using these AR models can accurately estimate the Rayleigh fading process. The accuracy of the new Kalman filters is demonstrated in the tracking of simulated Rayleigh fading processes of different bandwidths.
