Synthesis and self-assembly studies of a new AIEE probe and its application in sensing amyloid fibrillation

We report self-assembly and photophysical properties of a new pyridothiazole based aggregation-induced-emission enhancement (AIEE) luminogen 4-(5-methoxy-thiazolo[4,5-b]pyridin-2-yl)benzoic acid (PTC1) and its application for the sensitive detection and monitoring of amyloid fibrillation. The self-assembling properties of the new AIEE probe are extensively studied by AFM and it was noted that as aggregation increases there is enhancement of fluorescence. The fluorescence of PTC1 is quenched upon addition of cupric (Cu2+) ions while the fluorescence is regenerated in the presence of amyloid fibers. AFM studies reveal that PTC1 self associate/aggregate to hairy micelle structures which gets disrupted on the addition of Cu2+ and again reassembles in the presence of amyloid fibers. Hence, the fluorescence quenching and regeneration may be attributed to disaggregation and AIE respectively. Further, a comparative analysis of the performance of PTC1 is done with the conventional ThT which confirms it to be a more sensitive probe for the detection of amyloid both in the presence and absence of Cu2+. Of note, a very simple, facile and cost-effective methodology for the detection of amyloid fibres is presented, wherein fluorescence quenching/enhancement can be visualized under UV without the use of sophisticated instrumentation techniques. To the best of our knowledge and literature survey, this is first report wherein the self-assembling properties of AIEE probe is studied extensively via microscopy and the photophysical properties compared w.r. t to the morphological transformations. The AIEE probe has been designed using an unusual pyridothiazole scaffold unlike the commonly used archetypal AIE scaffolds based on tetraphenylethene (TPE) and hexaphenylsilole (HPS) and hence, the work also has implications in designing new generation AIEE dyes based on novel scaffold reported.
Power losses prediction in poly-v belt transmissions: application to front engine accessory drives

This paper presents a method that permit to estimate a map of the power losses for any multi-pulley poly-v belt transmission. First, the work identifies and models the power losses in a simple two pulleys poly-v belt transmission, it focuses on the belt losses due to: the rubber hysteretic behavior, and the pulley-belt slip. The model developed is general so that it can be applied to any belt transmission. Finally, the developed model is extended to simulate the power losses of a multi pulley transmission such as a front engine accessory drives.

Efficacies of entomopathogenic fungi from Metarhizium, Beauveria and Isaria on German cockroach, Blattella germanica (L.) (Blattaria: Blattellidae)

: mker@ksu.edu. tr ABSTRACT Blattella germanica is an important pest and able to transmit various pathogens and parasites of human, cause allergic reactions and food contamination. Due to risks and problems related to currently employed chemicals for their control, use of entomopathogenic fungi as alternative control approach has been under investigation. In this study, seven entomopathogenic fungi isolated from soil samples and five fungal isolates obtained from entomopathogenic fungal cultures have been tested against B. germanica. The fungi belong to the species Beauveria bassiana (3 isolates), Metarhizium anisopliae (4 isolates), Isaria tenuipes (1 isolate), I. fumosorosea (3 isolates), and I. farinosa (1 isolate). Conidial suspensions of all twelve isolates were applied at 1x10 7 conidia ml -1 concentration to ten insects in each replication. Tests were carried out at 26±2 o C, 65±5% relative humidity in darkness with three replications. Eight isolates were found effective on B. germanica with mortalities varying between 60.0% and 96.7% in 14 days. The results indicated that Metarhizium isolates had the highest efficacies (83.3-95.8%) followed by Beauveria isolates (70.8-79.2%) and the isolates of Isaria had the lowest efficacies (50.0-70.8%). These isolates were as effective as the previously reported isolates of the same species with higher efficacy values. The most effective two isolates of M. anisopliae (S8-2 and S11-6) appear to be worth investigating further for developing a microbial control agent
Structural interaction with control systems

A monograph which assesses the state of the art of space vehicle design and development is presented. The monograph presents criteria and recommended practices for determining the structural data and a mathematical structural model of the vehicle needed for accurate prediction of structure and control-system interaction; for design to minimize undesirable interactions between the structure and the control system; and for determining techniques to achieve the maximum desirable interactions and associated structural design benefits. All space vehicles are treated, including launch vehicles, spacecraft, and entry vehicles. Important structural characteristics which affect the structural model used for structural and control-system interaction analysis are given.
The quest for economic stability: a study on Swedish stabilisation policies 1873–2019

ABSTRACT This paper explores the evolution of Swedish stabilisation policies through six policy regimes between 1873 and 2019. We focus on discretionary policy decisions by estimating policy shocks using a SVAR model. Through these shocks, we explore how stabilisation policies have evolved over time and how policymakers responded to key economic events such as financial crises and wars. Our results show three key results (i) policies are often a source of destabilisation rather than stabilisation, (ii) regimes are designed for a specific time and ends when economic circumstances change, and (iii) fixed exchange rates worsen the economic effects of financial crises.

TPL-PCRUN Statement of methods

TPL-PCRUN is a software program for the dynamic interaction simulation of pantograph–catenary systems. In the benchmark, based on the finite element method, the catenary model was built and the pantograph was considered as a three-level spring–damper–mass system. Then, through the contact definition between pantograph and catenary, the coupled model of the pantograph and catenary system was established. The respective dynamic equations of motions were solved by the time integration method. Thus, the simulation results were obtained and submitted for the comparison with the other software. On the other hand, a standard model from EN50318 was established and analysed by TPL-PCRUN. The simulation results by TPL-PCRUN were remarkably consistent with the reference values given by EN50318. It was proved that the results by TPL-PCRUN can be reliable. Recently, the software has been updated and improved. Some new models and algorithms are proposed, including the rigid–flexible hybrid pantograph model, contact definition considering appearance characteristics of the contact surfaces, a fluid–solid coupling algorithm of the pantograph and catenary system, etc.
EVALUATION OF SOME MEDICINAL PLANTS AS PUTATIVE HIV-PROTEASE INHIBITORS

Aqueous extracts of Ocimum sanctum Linn. , Tinospora cordifolia (Willd.) Miers ex Hook. f. & Thoms, Withania somnifera Dunal, Avicennia officinalis Linn. and Rhizophora mucronata Lam. were included for the present in vitro study. Pepsin was used as a substitute for HIV-protease to evaluate inhibitory activity of these extracts, as pepsin has close resemblance with HIV-protease in proteolytic activity. O. sanctum revealed the highest inhibitory activity followed by R. mucronata. In our earlier study, O. sanctum and R. mucronata exerted anti-HIV activity via multiple mechanisms of action; viz., interference with the gp120 / CD4 interaction and inhibition of HIV-reverse transcriptase. In the present study, they also showed potent inhibitory activity against pepsin enzyme (indirectly against HIV-protease) which may be due their flavonoids content.
Control of Subsurface Flow using Model Predictive Control Techniques

1. Abstract Great efiort has been devoted to constructing high-order reservoir models for improved oil recovery. Several models of varying complexity have already been tested and understood. However, these models entail large amounts of computational efiort in order to obtain accurate solutions in a reasonable time. Reservoir management, in this case, has been performed in manual, ad hoc fashion, and sometimes, decisions are based on experience of production engineers. However, recently, the oil industry has started instrumenting and deploying various controls for enhancement of hydrocarbon extraction, specially involving down-hole measurements and controls of well bore in what is known as smart wells technology. Optimization techniques, such as model predictive control (MPC) has been successfully applied in the downstream end of the production line, and in general in the process industry. This is due to the fact that MPC is a model based controller design procedure, which can handle processes with stability issues and time-delays, together with a framework to incorporate constraints into the design. In this paper, we seek to apply real-time optimal control to reservoir management, and in particular to reservoir production. Based on the success of model-based optimization to the process industry, we aim to use MPC schemes to increase the potential for greater oil recovery, and therefore, enhanced reservoir management and profltability. MPC ofiers a robust control implementation together with constraint handling capabilities. At flrst, the dynamics of an oil-reservoir is introduced and the basic equations for ∞ow in porous media is presented. Then, linear MPC is applied and the focus is directed to the generation of low-order reservoir models using subspace identiflcation methods. Lastly, due to the highly nonlinear behavior of the reservoir models, it is suggested the use of nonlinear (NMPC) schemes. Comparisons will be provided through a set of realistic simulations using an in-house simulator. 2. Keywords: Optimal Control, Model Reduction , MPC, Reservoir Management.
An Overall Evaluation on Benefits of Competitive Influence Diffusion

Influence maximization (IM) is a representative and classic problem that has been studied extensively before. The most important application derived from the IM problem is viral marketing. Take us as a promoter, we want to get benefits from the influence diffusion in a given social network, where each influenced (activated) user is associated with a benefit. However, there is often competing information initiated by our rivals that diffuses in the same social network at the same time. Consider such a scenario, a user is influenced by both our information and our rivals’ information. Here, the benefit from this user should be weakened to a certain degree. How to quantify the degree of weakening? Based on that, we propose an overall evaluation on benefits of influence (OEBI) problem. We prove the objective function of the OEBI problem is not monotone, not submodular, and not supermodular. Fortunately, we can decompose this objective function into the difference of two submodular functions and adopt a modular-modular procedure to approximate it with a data-dependent approximation guarantee. Because of the difficulty to compute the exact objective value, we design a group of unbiased estimators by exploiting the idea of reverse influence sampling, which can improve time efficiency significantly without losing its approximation ratio. Finally, numerical experiments on real datasets verified the effectiveness of our approaches regardless of performance and efficiency.

Decontamination of bioaerosols within engineering tolerances of aircraft materials

Abstract : This document is the final report for Decontamination of Bioaerosols within Engineering Tolerances of Aircraft project funded by AFMSA/SG5I. This report discusses how aluminum and plastic coupons indicative of aircraft materials can be decontaminated using high heat and humidity. These tests were performed using a Bacillus anthracis spore simulant delivered through a novel aerosol deposition chamber and also direct inoculation. The results showed that the spores delivered through aerosol methods were decontaminated quicker than those that were directly inoculated. The tests verified that these spores can be effectively decontaminated if the proper heat and humidity levels are applied for the appropriate times.
A Method to Measure the Amount of Battlefield Situation Information

Abstract : One of the essential issues in C4ISR is to properly measure the amount of Battlefield Situation Information (BSI), which is a key concept in the research of Situation Awareness and decision-making. BSI contains two mutually independent contributions from current status information, which describes objective state of a certain battlefield situation element at the moment, and from trends information, which expresses changes of element's state that may occur in the future. But measure the amount of BSI has not been thoroughly studied before. Here we report a novel method that precisely measures the amount of BSI on the basis of Shannon's information theory. Our method gives the first accurate quantification on current status information as well as trends information contained in BSI. Necessary conditions for two C2 nodes to reach a consensus in the process of Situation Awareness are also provided in current work.
Removal the acid blue-15 dye from water by chitosan: kinetic and thermodynamic study

This study concerns the removal of acid blue-15 (AB-15) from water using chitosan through the batch sorption. To get the best percentage of removal, several experimental parameters have been used such as the initial concentration, temperature, and pH. The results show that the pH of the interaction medium does not indicate a significant influence in the adsorption process. In addition, the percentage of removal increased with the increase of dosage of chitosan and temperature of the reaction vessel. Furthermore, the percentage of removal decreases with the increase in the initial concentration of the AB-15 solution. The adsorption of AB-15 on the chitosan fits better with the Freundlich (R2= 0.998) than the Langmuir model. The adsorption kinetics follows the pseudo-first order (R2> 0.998) but not the pseudo-second-order model. The obtained results of this study show that chitosan has a potential application as a membrane to remove the AB-15 from industrial effluents.
Social Digital Objects for Grandparents

This paper describes a collaboration between the University of Dundee and Microsoft Research in which product design and interaction design students were asked to design digital products for older users. The project offered an introduction to inclusive design for the students. Rather than approach this in terms of designing for the whole population, they each designed with and for a particular grandparent. And rather than consider the accessibility of an existing product, they used this perspective to catalyse radical thoughts of future roles for digital technology. The various stages of the project are described, from initial user research through prototyping to final presentation at Microsoft's Design Expo in Redmond. Reflections are included from the audience at this event, the students, their tutors and our industrial partners. The paper ends with a short consideration of the role of digital technology in our everyday social interactions. At Microsoft this is part of Socio-Digital Systems research and at Dundee we have started to call this Social Digital.
Perspectives on Studying Collaboration in Distributed Networks

Abstract : This report describes cognitive variables and frameworks that are useful in the investigation of network collaboration in Army environments. Network collaboration is currently under study by the U.S. Army Research Institute for the Behavioral and Social Sciences (ARI) in the context of performance in a simulated network task using the game SCUDHunt. SCUDHunt was developed by ThoughtLink, Incorporated for the Defense Advanced Research Projects Agency (DARPA). The use of SCUDHunt does not constitute endorsement of the product by ARI, the U.S. Army or the U.S. Department of Defense. Key variables that facilitate functioning in this simulated network environment are discussed, based on the results of interviews with proficient SCUDHunt players. Frameworks for examining the data from the SCUDHunt studies are presented. Finally, brief recommendations for the directions of future research in this domain are presented.
Second-Order Total Generalized Variation Regularization for Pansharpening

Pansharpening can be regarded as an inverse problem, where a high-resolution multispectral (MS) image is estimated given a low-resolution MS image and a panchromatic (Pan) image. Considering the effectiveness of total generalized variation (TGV) to regularize ill-posed inverse problems, this letter proposes a variational model in accordance with the observation model based on the satellite imaging system and the second-order TGV. Furthermore, a primal–dual algorithm is adopted to resolve the variational model by splitting it into a sequence of simpler sub-problems, which leads to a more efficient algorithm compared to the other variational methods. In addition, the exploitation of TGV in the variational model allows the presence of the very fine details of the Pan image in the sharpened MS image whereas it is beyond the capabilities of the total variation (TV)-based models. The proposed algorithm is compared with some recent classical and variational pansharpening methods by experiments on two data sets at full and reduced resolution.
Analysis and Optimal Design of Mid-Range WPT System Based on Multiple Repeaters

In this article, an optimal design for mid-range wireless power transfer system based on multiple repeaters is proposed, which aims at powering high-voltage side sense module in HVdc applications. The mathematical model of the system is established. The characteristics of current distribution and impedance angle are analyzed under equally spaced situations. To further optimize the system, the optimized spaced structure with different distances is investigated, which can improve transferring efficiency under same distance requirement. The effect of load is also analyzed. A 1.5 m prototype with eight repeaters is built and the experimental results verify the feasibility of optimized coil arrangement, which can effectively improve efficiency, especially under light load situations.
Initial placement methods for Haitian adult ESOL students : the NYS place test plus profile data compared to subjective assessment

OF THE DISSERTATION INITIAL PLACEMENT METHODS FOR HAITIAN ADULT ESOL STUDENTS: THE NYS PLACE TEST PLUS PROFILE DATA COMPARED TO SUBJECTIVE ASSESSMENT by Dorothy R. Alterman Florida International University, 1994 Professor Douglas Smith, Major Professor Few valid and reliable placement procedures are available to assess the English language proficiency of adults who enroll in English for Speakers of Other Languages (ESOL) programs. Whereas placement material exists for children and university ESOL students, the needs of students in adult community education programs have not been adequately addressed. Furthermore, the research suggests that a number of variables, such as, native language, age, prior schooling, length of residence, and employment are related to second language acquisition. Numerous studies contribute to our understanding of the relationship of these factors to second language acquisition of Spanish-speaking students. Again, there is a void in the research investigating the factors affecting
Parameter sensitivity maps of surface geoelectric arrays

Parameter sensitivity maps allow a better understanding of various geoelectric responses, and they are also helpful in designing optimal new arrays for specific problems. We constructed systematic parameter sensitivity maps for various geoelectric arrays, and in this paper several examples are presented, among others for non-linear and focussed arrays. Our parameter sensitivity values are computed from the response of a small-size cube in a homogeneous subsurface at three different depths. Instead of 3D numerical modelling results we consider the small cube as a superposition of three electric dipoles, corresponding to the electric charge accumulation at the opposite cube faces. We apply simple analytical formulas and we present the parameter sensitivity values separately for the individual dipoles. Several theoretical and practical aspects are discussed. We recommend a methodical use of parameter sensitivity maps in geoelectric prospecting.
