Theoretical Investigation of Design Methodology, Optimized Molecular Geometries, and Electronic Properties of Benzene-Based Single Molecular Switch with Metal Nanoelectrodes

Understanding the electronic properties at the single molecular level is the first step in designing functional electronic devices using individual molecules. This paper proposes a simulation methodology for the design of a single molecular switch. A single molecular switch has two stable states that possess different chemical configurations. The methodology is implemented for 1,4-benzene dithiol (BDT) molecule with gold, silver, platinum, and palladium metal nanoelectrodes. The electronic properties of the designed metal-molecule-metal sandwich structure have been investigated using density functional theory (DFT) and Hartree-Fock (HF) method. It has been perceived that the DFT and HF values are slightly different as HF calculation does not include an electron-electron interaction term. Computation of the switching ratio gives the insight that BDT with gold has a high switching ratio of 0.88 compared with other three metal nanoelectrodes. Further, calculations of quantum chemical descriptors, analysis of the density of states (DOS) spectrum, and frontier molecular orbitals for both the stable states (i.e., ON and OFF state geometries) have been carried out. Exploring the band gap, ionization potential, and potential energy of two stable states reveals that the ON state molecule shows slightly higher conductivity and better stability than the OFF state molecule for every chosen electrode in this work. The proposed methodology for the single molecular switch design suggests an eclectic promise for the application of these new materials in novel single molecular nanodevices.
FORMULATION AND EVALUATION OF MUCOADHESIVE TABLET OF PANTOPRAZOLE SODIUM

Pantoprazole sodium (PAS) is a proton pump inhibitor, with an anti-ulcer activity. Due to the short elimination half-life and poor bioavailability, it’s rapidly degrades in gastro intestinal tract (GIT). An objective of work, to formulate mucoadhesive tablets for prolongation of drug release and preventing GI degradation. PAS tablets formulated using different concentration of HPMC and Xanthan gum by wet granulation technique and evaluated characterizations. Prepared granules were subjected to the pre-compression and post-compression evaluations, and there is no significant variation of tablets. PAS 3 showed better ex-vivo mucoadhesive strength (31.44±1.06g), and force (3.08±0.072N), highest in-vitro mucoadhesion time (476±0.596 min) and good swelling index (82.07%). PAS 3 had proven 79.48% drug release at end of dissolution studies and the mechanism of drug release kinetics was analyzed. Overall, optimized EPAS 3 formulation was evaluated the relevant parameters. GRDDS mucoadhesive tablets were shown satisfactory sustained release and suitable for potential therapeutic effects.
CS265/CME309: Randomized Algorithms and Probabilistic Analysis Lecture #9: Compressed Sensing and the Restricted Isometry Property

A vector x ∈ R is sparse if it has only a few large components. Sparsity shows up all over the place in real-world data. For example, we hope that vectors indicating errors or anomolies will be sparse. Even things that we might not think of as sparse—like natural images or human speech— tend to be pretty sparse when they are transformed into the correct basis. In this lecture, we’ll build on the ideas we saw in the previous lecture about the Johnson-Lindenstrauss transform to see how to do dimension reduction for the set of sparse vectors, and an application of this called compressed sensing.

An Effective Method for Autonomous Localization and Navigation in Unknown Indoor Environment using MAV

Localization in GPS-denied indoor environment is one of the biggest challenge in robotics field especially in aerial robots. Limited payload of micro air vehicles (MAVs) makes indoor navigation even harder as compared to ground robots. In this manuscript, we explore an effective method for indoor localization using two 2D laser scanners for map and obstacles detection, that can be processed onboard. Key idea and algorithm of the proposed method will be discussed in detail, starting from laser data feature extraction to rotational tracking, then to feature association, followed by position tracking. The localization method is implemented to a quadrotor MAV of dimension lesser than 90 cm and weight less than 3 kg. This method is proven to be effective and reliable throughout flight tests in different indoor scenario, including the indoor mission of the IMAV 2014 Competition that was held in Delft, the Netherlands.
Interrater reliability of Kraus - Weber exercise test as an evaluation tool in low back pain susceptibility among apparently healthy physiotherapy students

Background: The Kraus-Weber Test, involves a series of tests that measure minimum strength & flexibility of the back, abdominals, psoas, and hamstring muscles. But it has less number of article available for the adult population. For the clinician, the Kraus-Weber Test is made to reduce the assessment time in clinics and easily administer and less time-consuming. Aim & Objective: To determine the inter-rater reliability of the Kraus-weber Test in physiotherapy students. Methods: 426 subjects (59 male and 367 females); ages ranging between 19-22 years, with no previous or present complaints of injury to the back & lower limbs were selected for the study using the purposive sampling technique of sample of convenience. For inter-rater 2 raters were assessed K-W Test in 426 subjects. All raters were blinded to the procedure. Before collecting the data, training to each rater was given for the administration of the K-W Test. Results: For reliability, ICC has been checked and for responsiveness & distribution based method, SEM & SRD has been analyzed. The K-W Test shows good inter-rater reliability by ICC value. ICC of inter-rater reliability for (A+), (A-) & (FL) is 1, for (P) is 0.998, for (UB) is 0.999 and for (LB) is 0.999. SEM value for inter-rater also finds & it shows there is less error that has been detected in all 2 raters. Conclusion: K-W Test is very reliable tool to access fitness in physiotherapy students.
Inferring Perceptions of Control from Speech

Perceived Control or Perceptions of Control is defined as the belief that one can determine one’s own internal states and behavior, influence one’s environment, and/or bring about desired outcomes [1]. Individuals with a high Perceived Control are linked to positive mental health whereas individuals with a low Perceived Control are linked to depression and poor mental health. What we propose is to use a state-of-the-art Speech Emotion Recognition algorithm to infer Perceived Control from voice.
Integrating Approximate Duplicate Detection into Pentaho Data Integration

Data has increasingly become a fundamental asset for the great majority of companies and it keeps being produced at a very high rate. Large datasets are prone to data quality problems that can have a negative impact on the results of the analysis based on the data. The presence of approximate duplicate records is a data quality problem that arises commonly in a data integration context. Data integration consists in a set of processes that enable the integration of different data sources. Approximate duplicate records are records that represent the same real-world entity. If this problem is not detected, these records are processed as separate entities, influencing the results of analysis performed on the data. For example, if a client is present in two different data sources that are integrated, that client’s record may be duplicated in the final data source and the client will be treated as two different clients. Data integration tools can benefit from an approximate duplicate detection mechanism, but not all tools provide one. Pentaho Data Integration (PDI) is an open source data integration tool that was used as a case study for the inclusion of approximate duplicate detection. This work proposes two PDI steps that allow the user to compute approximate duplicates. These steps compute groups where all the elements of each group are considered approximate duplicates that represent the same real-world entity. There were also modifications made to an already existing PDI visualization to facilitate the visualization of the steps results. Our solution was evaluated considering correctness, performance and usability. The results of the evaluation were overall positive, offering users the possibility to compute approximate duplicate records without having to perform cartesian products of the data and without the need to be highly familiar with PDI.
Über die Quantitativen Veränderungen des Zinkgehaltes in der Hippocampusformation nach der Dithizon-Zufuhr

Mit der Sulfid-Silber-Methode wurden die quantitativen Veranderungen des Zinks in der Hippocampusformation der Maus nach der Dithizon-Zufuhr histochemisch untersucht. Die in den Feldern h3, h4 und h5 des Hippocampus und dem Gyrus dentatus histochemisch nachweisbare intensive Zinkreaktion ist durch die vorubergehend vollkommen verschwunden. 5 Stunden nach der Dithizon-Gabe wurde die Reaktion wieder in den fruheren normalen Zustand zuruckversetzt. Der Einflus des Dithizons auf die Zinkverteilung in der Hippocampusformation wurde nach dem Vergleich mit den Pankreasinseln diskutiert.

Quantifying Adaptation Costs in Sequential FDI Location Choices: Evidence from German Firms∗

When engaging in foreign direct investment (FDI) for the first time, multinational firms often incur large costs. They have to adapt to different business practices, ethical norms and regulations in a new country. Therefore, prior investment experience in a location can influence firms’ FDI decisions in subsequent periods, since firms do not need to pay the adaptation costs if they invest in the same location again. In this context, I develop a structural dynamic model of how firms make sequential decisions of where to invest. Using data on German firms’ FDI from 2002 to 2009, I estimate the model allowing for country-specific adaptation costs and firms’ heterogeneous preference towards location attributes. Estimation results suggest that adaptation costs are statistically and economically significant, ranging from 1.7%−34.3% of the average expected discounted profit of a firm. If adaptation costs were subsidized completely, I find that firms’ FDI location choices would change dramatically. In addition, the average expected discounted profit would increase by 20.6%, not only due to the reduction of adaptation costs, but more importantly, due to a better matching between firms and locations.

Different Assessments of the Effect of Drying Rates on Recalcitrant Seed Material

The results of the germination and tetrazolium (TZ) tests of axes of Pisum sativum, Quercus robur and Trichilia dregeana were in agreement during both drying and wet storage. The TZ test overestimated viability of Avicennia marina, Trichilia emetica and Strychnos madagascariensis axes in comparison to the germination test during dehydration. Thus, the germination test is a method of choice during desiccation and the TZ test may be a better indicator of viability during hydrated storage than drying. The survival of axes of Q. robur during slow dehydration and moist storage was unexpectedly poor possibly as a result of an unfavourable temperature during treatments. Hence, rapid desiccation is recommended for determinations of minimum ‘critical water contents’. The relationship between electrolyte leakage and water content during drying and wet storage of axes of T. dregeana harvested in 2001 and S. madagascariensis showed a ‘classic pattern’ as dehydration and hydrated storage proceeded. Consequently, the conductivity test is a poor measure of the ‘critical water contents’ but may be an indicator of differences in vigour among harvests of the same species along with the germination and TZ tests during slow desiccation. Less leakage occurred during rapid than slow drying in all species. Desiccation-sensitive seeds can be divided into three categories on the basis of the predominant mechanism of loss of viability during dehydration: minimally, moderately and highly desiccation-sensitive in which desiccation, metabolic and physical damage predominate, respectively. Irrespective of the mode of dying, the effect of rate drying of was always apparent.
Marine Nitrous Oxide Emissions From Three Eastern Boundary Upwelling Systems Inferred From Atmospheric Observations

Eastern Boundary Upwelling Systems (EBUSs) are coastal hotspots of the potent greenhouse gas nitrous oxide (N2O). However, estimates of their emissions suffer from large uncertainties due to their significant spatial and temporal heterogeneity. Here, we derive the first multiyear, monthly resolution N2O emissions from three of the four major EBUSs using high‐frequency coastal atmospheric measurements and an inverse method. We find average combined N2O emissions from the northern California, Benguela, and southern Canary upwelling systems to be 57.7 (51.4–63.9) Gg‐N yr−1. We also find an offshore region near the Benguela EBUS that exhibits large pulses of emissions with emissions that reach 677 Gg‐N yr−1 in 1 month. Our findings highlight that atmospheric measurements coupled with inverse modeling can capture the large variability in EBUS emissions by quantifying emissions over large spatial distances and over long time periods compared to previous methods using traditional oceanographic measurements.
A Trajectory Planning Algorithm for Medical Manipulators Based on Adaptive Particle Swarm Optimization and Fuzzy Neural Network

Received: 18 March 2020 Accepted: 1 June 2020 With the development of smart healthcare, surgical and rehabilitation robots have permeated into daily medical operations. This raises concerns over the trajectory planning of medical manipulators. Based on particle swarm optimization (PSO) algorithm and fuzzy neural network (FNN), this paper puts forward a trajectory planning algorithm for medical manipulators, which ensures that the target medical manipulator can suppress the residual jitter at the end, while meeting the requirements of high precision, flexible operation, and disturbance resistance. Specifically, a kinetic model was constructed for a medical manipulator of multi-degrees-of-freedoms (DOFs) through position and posture transforms, and used to construct an FNN for trajectory planning. To suppress the jitter at the end, an adaptive PSO algorithm was designed, and combined with the FNN into a trajectory planning algorithm called PSO neural network (PSONN) algorithm. Finally, the proposed algorithm was proved effective through experiments. The research results provide the reference for applying PSO algorithm and FNN in other fields.
Comparison of the Anti-Legionella Fill Material against Standard Polypropylene Fill Material in Model Cooling Tower Water System

Objective: Cooling towers are heat exchangers which are utilized in specific industrial devices. They possess the potential to support Legionella bacteria. The objective was to evaluate the efficacy of biocide impregnated polymer against regular polypropylene polymer in terms of anti-Legionella features during a 120-day period. Materials and Methods: To reduce the bacterial colonization in towers, anti-Legionella splash fill and regular polypropylene splash fill material were tested to compare anti-Legionella activity and biofilm formation potential within a 120-day period using a lab-scale recirculating cooling tower model system. The system was experimentally infected with Legionella suspension and operated continuously for 120 days. Results: Legionella colonization occurred on both test material surfaces beginning at the first month. Legionella counts on surfaces were increased over time on standard polypropylene surfaces. The product with anti-Legionella activity showed significantly lower Legionella colonization in comparison to standard polypropylene fill. Conclusion: The product with anti-Legionella activity has a significant biocidal effect against surface-associated Legionella under the above-mentioned conditions which mimics cooling tower water systems. Product seems to facilitate effective control program criteria against Legionella colonization in cooling towers.

Optimising the Structural Design of Small Wind Turbine Blades

Static and modal testing of a blade from a 15 kW wind turbine is presented. Static testing is performed with a Whiffle tree test rig to determine the structural response of the blade. The blade mass, deflections and natural frequencies are reported and these results are used to validate a finite element model of the blade. The FE model is then used in a design optimisation study. Parametric blade models are generated using the Python programming language based on manufacturing specifications. The goal of the optimisation study is to maximise the stiffness and reduce the mass of the blade. A multi-objective genetic algorithm (NSGA-II) is used to determine the optimum laminate thicknesses along the length of the blade. The finite element model shows good agreement with the experimental results. The optimisation study produced a set of Pareto efficient blade designs with up to 17% improvement in stiffness or 30% reduction in mass.
Dimensionality and Structure in Cancer Genomics: A Statistical Learning Perspective

Computational analysis of genomic data has transformed research and clinical practice in oncology. Machine learning and AI advancements hold promise for answering theoretical and practical questions. While the modern researcher has access to a catalogue of tools from disciplines such as natural language processing and image recognition, before browsing for our favourite off-the-shelf technique it is worth asking a sequence of questions. What sort of data are we dealing with in cancer genomics? Do we have enough of it to be successful without designing into our models what we already know about its structure? If our methods do work, will we understand why? Are our tools robust enough to be applied in clinical practice? If so, are the technologies upon which they rely economically viable? While we will not answer all of these questions, we will provide language with which to discuss them. Understanding how much information we can expect to extract from data is a statistical question.
GS2017-7: Sub-Phanerozoic basement geology south of Wekusko Lake, eastern Flin Flon belt, north-central Manitoba (parts of NTS 63J5, 12, 63K8, 9): insights from drillcore observations and whole-rock geochemistry of mafic rocks

Report of Activities 2017 Introduction The Flin Flon belt (FFB) consists of a series of oceanic assemblages that were formed and tectonically juxtaposed during closure of the Proterozoic Manikewan Ocean (e.g., Stauffer, 1984; Syme and Bailes, 1993), and is one of a series of belts that make up the internal Reindeer zone of the Paleoproterozoic Trans-Hudson orogen (Lewry and Collerson, 1990). Volcanic assemblages (ca. 1.9–1.8 Ga) include juvenile island-arc, juvenile ocean-floor/back-arc, and ocean-island basalt (Syme et al., 1999). Following the accretion of oceanic volcanic assemblages was the emplacement of ‘successor’-arc plutons (1.87–1.83 Ga; e.g., Whalen et al., 1999). Fluvial-alluvial sandstone and conglomerate of the Missi group (1.85–1.83 Ga) unconformably overlie older volcanic rocks (e.g., Ansdell et al., 1992; Syme et al., 1999). Burntwood group (1.85–1.84 Ga) greywacke and argillite is considered the lateral facies equivalents to the Missi group (e.g., Ansdell et al., 1995).
