The Design of a Hall Effect Current Transformer and Examination of The Linearity with Real Time Parameter Estimation

Today, the Hall sensor based current measurement is being widely used as they have both AC and DC current measurement capability. The factors such as ratiometric error of Hall sensor, earth or other magnetic effects in sensor location, sensitivity errors originating from temperature or magnetic core, deteriorates measurement linearity. This requires that measurement results are evaluated with mathematical analysis methods. In this study, a closed loop Hall Effect current transformer was designed and its linearity in measurement results is examined by real time parameter estimation based on the least squares method so measurement accuracy was improved and real time observation of linearity error was provided.
Trophic Transfer and Toxicity of (Mixtures of) Ag and TiO2 Nanoparticles in the Lettuce–Terrestrial Snail Food Chain

The increasing application of biosolids and agrochemicals containing silver nanoparticles (AgNPs) and titanium dioxide nanoparticles (TiO2NPs) results in their inevitable accumulation in soil, with unknown implications along terrestrial food chains. Here, the trophic transfer of single NPs and a mixture of AgNPs and TiO2NPs from lettuce to snails and their associated impacts on snails were investigated. Both AgNPs and TiO2NPs were transferred from lettuce to snails with trophic transfer factors (defined as the ratio of the Ag/Ti concentration in snail tissues to the Ag/Ti concentration in lettuce leaves) of 0.2–1.1 for Ag and 3.8–47 for Ti. Moreover, the majority of Ag captured by snails in the AgNP-containing treatments was excreted via feces, whereas more than 70% of Ti was distributed in the digestive gland of snails in the TiO2NP-containing treatments. Additionally, AgNP-containing treatments significantly inhibited the activity of snails, while TiO2NP-containing treatments significantly reduced feces excretion of snails. Furthermore, the concurrent application of AgNPs and TiO2NPs did not affect the biomagnification and distribution patterns of Ag and Ti in snails, whereas their co-existence exhibited more severe inhibition of the growth and activity of snails than in the case of applying AgNPs or TiO2NPs alone. This highlights the possibility of nanoparticle transfer to organisms of higher trophic levels via food chains and the associated risks to ecosystem health.
Image denoising in real-time system aided by simulation tools

Real-Time Image Acquisition System is as shown in Fig.1. "Digital Image noise" is equivalent to analog cameras. This noise appears as random speckles on an otherwise smooth surface and can significantly retrograde image quality [1-7]. There are outer and inner noise consisting in Image Acquisition System. In this paper we analyzed the noise generated causation, noise model and denoising method with the aid of simulation tools. Since increased current source / sink capability and faster switching edge rates result in an increase in ground bounce or noise caused by simultaneously switching outputs (SSOs) in the FPGA design. The noise can affect device reliability since it can trigger false edges on critical input signals [8]. Considering the characteristics of FPGAs, flexibility, inherent parallel characteristic and the rapid prototyping, a debugging technique of FPGA-based was designed with a Lattice ECP2M chip. The experiment results which include the time-consuming, the wave forms and the calculation cycles were analyzed with special tools, Protel99SE, ispLever 6.1, ModelSim, etc. and the Post-Place & Route layout of a project was shown in the end of this paper. It is concluded that we can deal with the inner noise problems on hardware platform, and find out some denoising methods.
Numerical simulations of high power near-infrared supercontinuum generation from a nonlinear fiber amplifier

Photonic crystal fiber has been widely used in visible and near-infrared supercontinuum generation due to its flexible dispersion control and high nonlinearity. However, the maximum average output power of supercontinuum from a photonic crystal fiber has not exceed one hundred watt owing to the small core diameter of the photonic crystal fiber and the low coupling efficiency between the pump and the photonic crystal fiber. Recently, supercontinuum generation directly from a nonlinear fiber amplifier attracts lots of attention as a result of its simple structure and low splicing loss and many excellent results have been achieved either in low and high average power, which is proved to be a promising method to realize kilowatt level high power near-infrared supercontinuum. However, the numerical study on high power near-infrared supercontinuum generation from a nonlinear fiber amplifier has been rarely reported, so there is great necessity to carry out some theoretical study on it. In this paper the complex Ginzburg-Landau equation is used to describe the formation and propagation of high power near-infrared supercontinuum generation in a nonlinear fiber amplifier. The chromatic dispersion of the ytterbium-doped fiber is measured by a Mach-Zehnder interferometer. The roles of the small signal gain, input pulse width and initial chirp of the input pulse played on the continuum formation are analyzed in detail. The results are in good agreement with the experiments which can provide some theoretical guidance on future optimization of the flatness and width of the supercontinuum generation from a nonlinear fiber amplifier.
Developing a research agenda on exercise and physical activity for people with limb loss in Canada

Abstract Purpose There is a lack of high-quality evidence about the effects of exercise or physical activity interventions for adults with lower limb amputations (LLAs). A planning meeting involving stakeholders (i.e., people with LLA, community advocates, health care providers, researchers) was organized to identify key research priorities related to exercise and physical activity for people with LLAs. Methods We used a collaborative prioritized planning process with a pre-meeting survey and 2-day virtual meeting that included: identification and prioritization of challenges or gaps; identification and consolidation of solutions; and action planning. This process integrated a modified Delphi approach, including anonymous feedback in two surveys. Results Thirty-five stakeholders participated. Six challenges related to exercise and physical activity for people with LLA were prioritized. One solution was prioritized for each challenge. After consolidation of solutions, participants developed five research action plans for research including: developing an on-line interface; developing and evaluating peer-support programs to support physical activity; examining integration of people with LLA into cardiac rehabilitation; development and evaluation of health provider education; and determining priority outcomes related to physical activity and exercise. Conclusions This collaborative process resulted in an action plan for amputation research and fostered collaborations to move identified priorities into action. IMPLICATIONS FOR REHABILITATION Lower limb amputations impact mobility leading to lower levels of physical activity. There are research gaps in our understanding of the effects of exercise or physical activity interventions for adults with lower limb amputations. Through a collaborative planning process, participants prioritized research directions on physical activity and exercise for people with LLA to advance research in the field. Action plans for research focused on developing online resources, peer support, cardiac rehabilitation for people with LLA, health provider education and determining priority outcomes related to physical activity and exercise.

Conflictological Model of Institutionalization of Economic Processes in the Agriculture

The institutional essence, structure and typology of conflicts in a market economy are determined. The components of typical conflicts have been studied, as well as analysis of the type of economic conflicts "power – business entities" in the agricultural sector. It is established that any disproportions of the socio-economic system lead, due to the relevant incidents, to the aggravation of conflict situations. It was found that the conflict situations are objectively based on the contradictions of the interests of the main groups of agents and, accordingly, the institutions of the system. The results of our research give grounds to assert that the institutional modernization of the agricultural sector is possible only if new types are prevented and the consequences of existing conflicts are reduced, which is a kind of scheme of evasion within public control. It is proved that one of the universal tools of the unobserved economy in the light of the conflict paradigm are certain types of institutional agreements, and this is a fundamentally new methodology for reflecting real processes.

Robust Charging Schedule for Autonomous Electric Vehicles With Uncertain Covariates

Autonomous electric vehicles (AEVs) will become an inevitable trend in the future transportation network and have an important impact on the power grid. It is difficult to find the optimal distributed charging solution for AEVs to minimize the system cost with some uncertainties. In this paper, we investigate an AEVs charging and discharging problem with vehicle-to-grid (V2G) services. We aim to minimize the total electricity cost and battery degradation cost of AEVs and charging station batteries with V2G services, which takes the random arrival and departure of AEVs into account. We first propose a distributed charging framework of AEVs and charging stations by clustering method with the constraint of limited AEVs for each charging station in a region and formulate a distributed offline optimization problem. Then we formulate a distributed online charging optimization problem and propose a distributed online AEV charging scheduling (DOAS) algorithm to get an optimal charging solution. To study a more practical case, we reformulate the distributed online optimization problem with the uncertainties from base loads, renewable energy and charging demands. Furthermore, to improve the time efficiency of DOAS algorithm, we reduce the dimension of the distributed problem and design a dimension-reduction DOAS (DDOAS) algorithm. To seek a robust solution with some uncertainties, we propose a DDOAS algorithm with DRO based on Wasserstein distance (DDODW). Simulation results show that DOAS and DDOAS algorithms can have a close-to-optimal charging cost and a significantly less battery degradation cost of charging stations, compared with centralized online charging scheduling algorithm and DDOAS algorithm is more time-efficient than DOAS algorithm. The proposed DDODW algorithm can provide a robust solution for the energy schedule
Verifiable Secret Sharing Scheme Based on the Plane Parametric Curve

Verifiable secret sharing is a special kind of secret sharing. In this paper, A secure and efficient threshold secret sharing scheme is proposed by using the plane parametric curve on the basis of the principle of secret sharing. And the performance of this threshold scheme is analyzed. The results reveal that the threshold scheme has its own advantage of one-parameter representation for a master key, and it is a perfect ideal secret sharing scheme. It can easily detect cheaters by single operation in the participants so that the probability of valid cheating is less than 1/p (where p is a large prime).

Physical Optics Modeling Of Systems With Multiple Lasers

Many laser systems use several laser beams which may interact either coherently or incoherently. Most physical optics codes model the propagation of a single laser beam. Some codes can analyze the kinetics of multiple laser lines. A powerful computer code, called LOTS2, has been developed at the Los Alamos National Laboratory by UNM which allows the simultaneous treatment of different laser beam trains. These beams may have different wavelengths, apertures, divergences, substantially different Fresnel numbers, and need not be colinear. Multiphoton phenomena such as Raman processes and isotope separation may be studied as well as conventional single photon phenomena. LOTS2 has a virtual memory feature that allows computer arrays to be larger than the central memory of mainframe machines such as the CDC 7600 and Cray 1. The separability of the diffraction propagation mathematics has been exploited to allow cylindrical lenses and high aspect ratio beam cross sections to be modeled. Considerable effort has been devoted to making the code easy to use.
Tunable active bandpass filters using three-terminal MESFET varactors

The concept of three-terminal MESFET varactors is presented. Based on this concept, two types of tunable active bandpass filters working at the X-band were developed. The first circuit used two MESFETs, of which one was used as a MESFET varactor and the other was used to generate a negative resistance. The second circuit used only one MESFET, which had both the functions of the two MESFETs in the first circuit. The experimental results showed the possibility of using the MESFET in the active mode to generate both a negative resistance and a variable reactance. <<ETX>>
More on the invisibility of CKD…… and counting

Lack of awareness of a diagnosis of chronic kidney disease (CKD) by patients and physicians is a major contributor to fueling the CKD pandemic by also making it invisible to researchers and health authorities. This is an urgent matter to tackle if dire predictions on future CKD burden are to be addressed. CKD is set to become the fifth global cause of death by 2040, and the second cause of death before the end of the century in some countries with long life expectancy. Coronavirus disease 2019 (COVID-19) illustrated this invisibility: only after summer 2020 it became clear that CKD was a major driver of COVID-19 mortality, both in terms of prevalence as a risk factor and of the risk conferred for lethal COVID-19. However, by that time the damage was done: news outlets and scientific publications continued to list diabetes and hypertension, but not CKD, as major risk factors for severe COVID-19. In a shocking recent example from Sweden, CKD was found to be diagnosed in just 23% of 57880 persons which fulfilled diagnostic criteria for CKD. In the very same large cohort, diabetes or cancer were diagnosed in 29% of persons, hypertension in 82%, cardiovascular disease in 39% and heart failure in 28%. Thus, from the point of view of physicians, patients and health authorities, CKD was the least common comorbidity in persons with CKD, ranking sixth, after other better-known conditions. One consequences of this lack of awareness, was that nephrotoxic medications were more commonly prescribed in patients with CKD that did not have a diagnosis of CKD. Low awareness of CKD may also fuel concepts such as the high prevalence of hypertensive nephropathy when CKD is diagnosed after the better-known condition of hypertension.
The Effect of Functional Biomechanics Garment for Walking

The purpose of this study was to investigate the effects of a functional biomechanics garment (FBG) with a lower extremity assist function. 32 healthy male participants were included in this study. Participants were divided into an FBG with taping function group (FBG group) and a compression garment group (CG group). Cadence (steps/min), step length (m), and usual walking speed (m/s) were measured as spatio-temporal data. Kinetics, kinematics data, and dynamic joint stiffness (DJS) of the lower extremity were calculated using a three-dimensional gait analysis system. The FBG group showed significantly faster walking speed (FBG, 1.54 ± 0.12 m/s; CG, 1.42 ± 0.15 m/s, p < 0.05) and reduced hip DJS in terminal stance (FBG, 0.033 ± 0.014 Nm/kg/degree; CG: 0.049 ± 0.016 Nm/kg/degree, p < 0.05) compared to the CG group. The FBG decreased hip DJS in the terminal stance and affected walking speed. The passive elastic moment generated by the high elasticity part of the hip joint front in the FBG supported the internal hip flexion moment. Therefore, our FBG has a biomechanical effect. The FBG may be useful as a tool to promote health activities.

Microarthropods and vegetation as biological indicators of soil quality studied in poor sandy sites at former military facilities

Biota play major roles in soil function and are highly sensitive to any disturbances including land degradation. However, it is not fully understood which organisms and what parameters can be useful in assessing soil quality. To fill this research gap we searched for good indicators of changes in environmental quality that could help to assess land degradation. Next to indicators using physical and chemical parameters, biological agents can also provide a lot of information. To obtain such knowledge we compared the soil quality of former military sites, which differed mainly in the texture, nutrients and organic carbon content based on fauna and vegetation indices. Among the fauna indices were Collembola and Acari abundance, Soil Biological Quality index (QBS‐ar), decomposition rate and feeding activity. The Ellenberg index was used as a vegetation indicator, in which the response to pH, nutrients, and moisture was analysed. The experiment was conducted at 2 former military sites in the Czech Republic. Site 2 was characterised by higher nutrient content and a more compact soil structure in comparison to site 1. It was found that almost all fauna and vegetation indices showed better soil quality in site 2. The significant changes were indicated by the Collembola abundance, QBS‐ar index and feeding activity, as well as response to pH considering vegetation indicators. Finally, we conclude the usefulness of biological indicators for monitoring the quality of soil, which can be adopted when making decisions concerning land use.
Using Low-Interaction Honeypots to Study the Abuse of Open Proxies to Send Spam

One of the main problems in creating effective mechanisms to mitigate the spam problem is the lack of more precise data on it.
