New Trends for Improving the Academic Advising System

Recently, the academic advising systems have been studied by several researchers in both technical and educational fields. However, most of the existing academic advising systems available in the universities include CAS College provides a manual academic advising system which are face some drawbacks and problems in the educational fields. This paper proposes a system which is used to automate the process of academic advising with the goal of avoiding the problems of the manual version of the academic advising system titled Intelligent aCademic aDvising( ICD) system. ICD is consisting of two main units. Each of these units is responsible to provide services for each of the advisors and students. Nevertheless, to reach a degree of automatic advising by the ICD system, GA mechanism is adopted in the suggested units. The GA helps the ICD system to provide the student with a reasonable recommendation to his\her marks in the current registered semester if he/she is under proration. In addition to the suggested main units, ICD able to displays the number of the completed credits, GPA, the study plan and the courses that they don't completed. All these features of ICD make the advisor a useful system for those under proportion students. ICD is developed with one database which is built within web applications employing Apache Web Server, MySQL, Java Server Pages and NetBeans. The performance of ICD in the college of applied science has been evaluated during an experiment with experienced advisors and 50 students of this college.
How Random Is a Random Polymer Coil

Short range order within amorphous, random polymer structures is a well known and widely studied property of disordered systems. An aggregate of five random atactic chains, each comprising 400 building units was computer-generated and then used to calculate neutron coherent scattering intensity for 0.01 < Q < 30 nm−1 (0.001 < Q < 3 A−1). The latter was compared with experimental data within the diffuse scattering range. On the grounds of quantum chemical calculations for an atactic polystyrene tetramer and the above information it is concluded that interactions among phenyl rings are responsible for the onset of the local order in this polymer.
Unveiling mediastinal pathology: role of EUS guided fine needle aspiration in diagnosing mediastinal lesions

Background: Mediastinal lesion is the focus of investigation in diagnosis of infective, granulomatous or neoplastic pathology of respiratory system. Metastatic mediastinal node assessment is an integral part of oncological management. EUS provides access to sampling of mediastinal mass, sub-carinal and aorto-pulmonary nodes. This study aims to assess the clinical impact, diagnostic yield and safety of EUS guided FNA for mediastinal lesions.Methods: Retrospective analysis of prospectively collected data of 72 cases of mediastinal lesions between January 2014 and December 2017 was done. EUS-FNA was performed with a linear echoendoscope using a 22- or 25-gauge needle. Adequacy of cellularity was assessed by on site pathologist. Patient data (demographics, intervention and follow-up) were prospectively collected and introduced in a predefined computer database for later review.Results: EUS-FNA was performed from 57 lymph nodes and 15 mediastinal masses. Adequate samples were obtained in 67 of 72 patients (93.05%). All mediastinal masses were malignant and were identified in the 3rd, 5th and 6th decade of life. Of the 57 lymph nodes, 15 were malignant, 28 had granulomatous lymphadenitis of which 16 individuals became asymptomatic after anti tubercular therapy. Sample was inadequate in 5 circumstances. No major complications were encountered with the procedure in any of the individuals.Conclusions: EUS guided tissue diagnosis is a safe technique and our data supports the use of EUS-FNA in work-up of mediastinal lesions. It is minimally invasive, accurate and has easy access to mediastinum. It has significant impact on patient diagnosis, management and should be considered over other invasive techniques.

Comparative evaluation of antigen detection ELISA and reverse transcriptase PCR in acute stage of Japanese encephalitis prevalent in endemic areas of North-Eastern part of Uttar Pradesh, India -

Background: Objective of current study was to compare and evaluate different diagnostic tests to establish a reliable and less time consuming diagnostic test for prompt diagnosis of acute Japanese encephalitis cases mainly amongst children and young adults from North-Eastern part of Uttar Pradesh. Methods: A total of 100 subjects, including 50 suspected cases and 50 diseased controls were investigated to establish the diagnosis of JE in acute encephalitis patients. All CSF samples were subjected to MAC-ELISA, virus cultivation and RT-PCR. Results: Out of 50 cases, 6 showed negative results by all the three tests. 50% (22 out of 44), 47.5% (21 out of 44), and 66% (23 out of 44) were found positive by MAC-ELISA, Virus cultivation and RT-PCR respectively. The rate of detection by Virus cultivation and RT-PCR was higher in case of MAC-ELISA negative cases (57.1% and 78.5%) than that of MAC-ELISA positive cases (22.7% and 27.2%) respectively. Mean age of the patients was 12.5 years, which ranged from 1-24 years with male to female ratio of 3:1. Conclusions: The RT-PCR was found most reliable, sensitive and specific method amongst the three chosen methods for detection of JEV in suspected encephalitis patients.
A Finite

Wire bonding is an unavoidable step in automotive industry. Multi-strand aluminum cables are used as battery cables inside an appropriate contact system in automobiles. These are for instance used for connection of different electronic components and electrical centers in automobiles. As an alternative for crimping technology in wire bonding, ultrasonic welding (USW) is applied, which is counted as a rapid manufacturing process in order to create solid state joints between thin materials at low temperature and low energy consumption compared to other common welding processes, such as oxy-fuel welding and arc welding. Ultrasonic welding of metals is a joining technique as a combination of applying pressure and frictional vibrations within the range of ultrasonic frequencies. In automotive industry, ultrasonic welding is often used for wired connections. An ultrasonic welding machine consists of different parts, such as pneumatic cylinder, piezoelectric converter, booster, sonotrode and anvil. Despite of the simplicity of the USW process, choosing the right machine and process parameters is a tricky and complicated task in order to obtain an adequate bond. Thermo-structural analysis of ultrasonic wire bonding has been performed by means of the 3D finite element method by Ding and Kim [1]. Thermomechanical analyses of ultrasonic welding of aluminium alloy have been performed by Siddiq and Ghassemieh [2]. The present work investigates the USW of a bundle of wires and focuses on the influence of some of the ultrasonic welding parameters, such as applied pressure on the wire bundle and vibrational amplitude of the sonotrode, on the temperature rise at the interfaces of each two strands in contact as well as the temperature distribution across the wire bundle. Microsections obtained during experimental investigations done in the present study show the softening of aluminum strands at some bonding parts within the wire bundle. This phenomenon can be an interpretation of a local temperature rise close to the melting point of aluminum. The obvious difference in microsections from different weld samples was a motivation for this study to further investigate the thermomechanical aspects of the problem by use of FEM simulations. The represented model is a simplification of the real case and is intended to investigate the temperature rise between strands in connection during ultrasonic welding.
Effect of different forms of pre-defined hypotheses on supporting inquiry learning in a simulation environment

The purpose of this study was to examine differences in effect of two forms of pre-defined hypotheses: to be falsified (TBF) and to be verified (TBV) hypotheses in a simulation-based inquiry learning environment. TBF and TBV hypotheses respectively denote pre-defined hypotheses that are meant to be falsified or verified by inquiry results. The present study used a quasi-experimental pretest and posttest design. The effect comparison was implemented based on both domain knowledge acquisition and inquiry process. Thirty-seven second-year Dutch students from a pre-university school were first grouped by gender and then randomly assigned to either one of the conditions to keep the same proportion of female and male students under each condition. Results showed no significant differences between conditions on both knowledge acquisition and inquiry process. Students’ beliefs on the given hypotheses were also considered as probable influencing factors. Comparison among students who were given different pre-defined hypotheses and held different beliefs on these hypotheses found no significant difference either, indicating students’ beliefs have the same non-significant impact on students from TBV and TBF group.
DNA SEQUENCE AND RAPD INFORMATION REAFFIRMS THE TAXONOMIC RELATIONSHIPS BETWEEN APOCYNUM VENETUM L . AND POACYNUM PICTUM ( SCHRENK ) BAILL

Medicinal plants Apocynum venetum L. and Poacynum pictum (Schrenk) Baill. having similar efficacy belong to two genera. However, many similarities of morphological characteristics in pollen, seeds, leaves and stems etc. between the two species recommend it under one genus Apocynum L. To address this question, we selected DNA sequences [nuclear rDNA internal transcribed spacer (ITS), trnL intron and trnL-trnF intergenic spacer (IGS) sequence] and RAPD markers to assess the relationship between them, with samples from 10 populations of A. venetum and 5 populations of P. pictum from China. ITS sequences from all samples of A. venetum and P. pictum were same, and only two different sites were found in the trnL intron region and one different site in the trnL-trnF IGS region. The genetic distance between A. venetum and P. pictum calculated upon these regions was much smaller than both the intergeneric and interspecies genetic distances calculated upon the same regions in the vast majority of plants. This reaffirmed the notion that A. venetum and P. pictum had a close genetic relationship. Results from RAPD markers showed that there was high similarity and still stable difference between A. venetum and P. pictum. The genetic difference between A. venetum and P. pictum was greater than the differences among populations within species. Our studies recommend that A. venetum and P. pictum were genetic close-related species and they may be treated within one genus.
Optimizing energy contracts for business enterprises and companies

Soaring electricity prices constitute a serious obstacle for both small and large business enterprises, since the costs of electricity are projected into the market prices of their goods and services. This paper analyzes the current conditions and offers some measures for optimization by the means of the parametric model that describes the conditions of power purchase agreements (PPA) for different groups of consumers with different demand profiles. We use the case study of PPAs contracts in Moscow, the Russian capital, in order to model the optimal power supply for three hypothetical customers: a meat factory, a car wash, and an office unit. We employ a Heaviside step unit function in order to model the consumer demand and to calculate the gains for various types of consumers. Our results demonstrate that consumers with higher energy consumption are better off when moving to across tariff zones changing the value of the contract. Moreover, it appears that changes into the investment policy of the hypothetical Russian enterprise enable it to lower the costs of energy and thence to increase the competitiveness of its good and services offered on the market. Our results might also be important in the context of the recent focus on the renewable energy and low-carbon future.
Exogenously applied polyamines ameliorate osmotic stress-induced damages and delay leaf rolling by improving the antioxidant system in maize genotypes

Leaf rolling (LR), particularly in crops, is a dehydration avoidance mechanism that results from water loss in plants under drought conditions. Two maize cultivars (Zea mays L.) differing in their tolerance to drought (cultivar Side was selected as stress-tolerant and cultivar Karacay was selected as stress-sensitive) under PEG-induced drought stress were used in this study to understand the effects of polyamines (PAs) on LR response and the role of the antioxidant system in the delayed LR process. Aerial parts of the seedlings were excised prior to the experiment and then submerged in a Hoagland nutrient solution with or without 0.1 mM Putrescine and 0.1 mM Spermine for 17 h, after which they were submitted to osmotic stress treatments (5% PEG) for 24 h. LR was physically prevented in order to clarify the relationship between PAs and antioxidant systems in LR response. Plants were evaluated by measuring the accumulation of hydrogen peroxide (H2O2), lipid peroxidation, antioxidant enzyme activities, and nonenzymatic antioxidant levels. Exogenous applications of PAs prevented water loss and delayed LR in comparison with the control (seedlings treated only with PEG). PAs almost totally prevented increases in lipid peroxidation. Antioxidant enzyme activities in rolled leaves were induced in response to osmotic stress in both maize seedlings via PA application. Ascorbate, glutathione, and endogenous PA levels increased as a result of PA applications. H2O2 content was lower in PA-pretreated plants than in the control in both cultivars. The activity/effectiveness of antioxidant system components of the physical prevention of leaf rolling (PLR) group of plants were lower than those of the group of plants with rolled leaves, especially in sensitive Karacay, whereas more induced H2O2 content and lipid peroxidation were determined in the PLR group. In addition, exogenous applications of PAs further increased the components of Side's antioxidant system in comparison with Karacay. When considered together, the data suggest that exogenous PAs may have a H2O2-mediated regulatory role in the LR process through the induction of antioxidant machinery. A stimulated antioxidant system decreases oxidative stress damage from excess accumulation of H2O2, thus delaying LR. In summary, exogenous PAs could help plants invert the adverse effects of osmotic stress and might play a key role in providing tolerance in plants through modulating the antioxidant system and decreasing H2O2 levels and water loss in plants via LR, as an alternative drought-protection mechanism. In addition, maize cultivars with late LR by PA applications may be provided as an opportunity for improving yield potential in drought-prone areas.
TESTING THE INJECTION OF THE LISA-PATHFINDER TEST MASS INTO GEODESIC CONDITIONS

LISA Pathfinder is a technology demonstration mission aimed at testing the free-fall purity level of a reference mass (or test mass, TM). Such an object can be used as a geodesic tracker for the detection of gravitational waves and is the core of the Gravitational Reference Sensor (GRS). The low acceleration noise level pursued for the tracker sets tight design constraints on the GRS. Any non-gravitational force has to be reduced to the level of 10 fN in the measurement bandwidth (1-30 mHz). The TM is firmly constrained by the Caging and Venting Mechanism (CVM) during the spacecraft launch and is then handed over to the Grabbing Positioning and Release Mechanism (GPRM). This mechanism is designed to handle the TM during in-orbit operations and inject it into the geodesic trajectory (or free-fall condition) by means of a quick retraction of two release tips on two opposed sides of the TM. After these operations, the TM residual velocity must be below 5 μm/s, otherwise the GRS capacitive position control is not able to capture and centre the TM in its electrode housing. Due to this criticality, the requirement on the maximum release velocity is verified on-ground both by means of an experimental apparatus (the Transferred Momentum Measurement Facility, TMMF) and by means of simulations. The TMMF is specifically designed to assess the contribution of adhesion between TM and release tips to the total TM momentum. On top of this contribution, any deviation from a symmetrical action of the two opposed release mechanisms determines an extra transferred momentum. Great care must be taken to correlate the experimental results with the in-flight conditions, where a different actuator is used to perform the TM injection. The extrapolation of the experimental results to in-flight conditions and the Montecarlo simulation of the GPRM-TM combined dynamics show the presence of a 2.4 margin factor with respect to the 5 μm/s requirement. ∗carlo.zanoni@unitn.it The on-ground measured and simulated performance of the injection phase, its challenges and critical points are here presented and discussed. For the first time, in this paper, the simulations take advantage of the large amount of data available from the testing campaigns.
Your Right Arm for a Publication in AER?

The time tradeoff (TTO) method is popular in medical decision making for valuing health states. We use it to elicit economists’ preferences for publishing in top economic journals and living without limbs. The economists value the journals highly, and have a clear preference between them, with American Economic Review (AER) the most preferred. Their responses imply they would sacrifice more than half a thumb for publishing in AER. The TTO results are consistent with ranking and willingness to pay results, and indicate that preferences for journals are neither guided by influence factors, nor by expectations of a resulting salary rise.
A brief play intervention to improve synchronous interactions and play skills in low income mother-child dyads.

Interaction synchrony defines how well a parent and child relate, with lower levels of synchrony associated with poor child outcomes. A 10-minute Parent-Child Interaction Therapy (PCIT) was tested in a pre-posttest design for improving interactional synchrony in 40 low-income mothers and preschool children (Half of the mothers watched a child nutrition video and served as a control group). As a group, the mother-child synchrony levels were low-to-average. Mothers in the PCIT group were taught five skills (PRIDE) to use when playing with their children: praise, reflect, imitate, describe, enthusiasm. The PRIDE group improved in interactional synchrony, whereas the control group did not. Mothers in the PRIDE group also used more child-directed techniques and their children were coded as offering their mothers toys more frequently. The findings suggest that a brief intervention may improve the interactional synchrony of low-income mothers and their preschool children, which may enhance preschool age childrenâ€™s social skills.
35 94 v 1 [ qu an tph ] 1 4 A pr 2 01 4 Generalized entanglement distillation

We present a way for entanglement distillation for genuine mixed state. Different from the conventional mixed state in entanglement purification protocol, each components of the mixed state in our protocol is a less-entangled state, while it is always a maximally entangled state. With the help of the weak cross-Kerr nonlinearity, this entanglement distillation protocol does not require the sophisticated single-photon detectors. Moreover, the distilled high quality entangled state can be retained to perform the further distillation. It makes more convenient in practical applications.
Rejoinder to Matte

I am writing in response to James Matte’s letter to the editor in regard to my article, “Is Matte’s Inside Track the Answer to False Positives, False Negatives and Countermeasures? There is Reason to Fear that Hope is Gone” (Cushman, 2013), which is published in the current edition of this journal. I will briefly address some of Matte’s assertions. While I tried to limit the former article to an analysis of the data and avoid a personal debate with any of the authors of the MQTZCT studies, Matte has written a response describing his personal thoughts describing how he conceived the technique and why he reasons it is superior to others. Any response of mine, therefore, may be viewed by some as an attack against the person of James Matte rather than what it is: a rejection of some of his faulty ideas, methods and conclusions. Again, I appreciate his zeal and tenacity. He is certainly a friend to the cause of elevating the status of polygraph. However, if we are to be gain credibility alongside our sister forensic sciences, it’s necessary to separate fact from fiction and be responsible enough to clearly report what we can reasonably conclude to know versus that which we have only conceived in our minds. Again, I respect James Matte as a colleague, but I would not want my silence to imply agreement, and therefore I provide a response. First, there is little, if any, new information in Matte’s arguments despite the fact that his letter is significantly longer than my article. In fact, much of what appears in his response appears verbatim in some of his other publications, most all of which are freely available on his website. Matte’s weak and specious arguments, despite having been re-stated multiple times, are still weak and specious arguments. Restating the same weak argument does not make it any stronger or any more valid. Moreover, it is inappropriate to reuse one’s prior work without properly citing those works (i.e., engage in self-plagiarism), especially when bypassing the peer-review process by submitting a letter to the editor.
