A LabVIEW-based electrical bioimpedance spectroscopic data interpreter (LEBISDI) for biological tissue impedance analysis and equivalent circuit modelling

Abstract Under an alternating electrical signal, biological tissues produce a complex electrical bioimpedance that is a function of tissue composition and applied signal frequencies. By studying the bioimpedance spectra of biological tissues over a wide range of frequencies, we can noninvasively probe the physiological properties of these tissues to detect possible pathological conditions. Electrical impedance spectroscopy (EIS) can provide the spectra that are needed to calculate impedance parameters within a wide range of frequencies. Before impedance parameters can be calculated and tissue information extracted, impedance spectra should be processed and analyzed by a dedicated software program. National Instruments (NI) Inc. offers LabVIEW, a fast, portable, robust, user-friendly platform for designing data-analyzing software. We developed a LabVIEW-based electrical bioimpedance spectroscopic data interpreter (LEBISDI) to analyze the electrical impedance spectra for tissue characterization in medical, biomedical and biological applications. Here, we test, calibrate and evaluate the performance of LEBISDI on the impedance data obtained from simulation studies as well as the practical EIS experimentations conducted on electronic circuit element combinations and the biological tissue samples. We analyze the Nyquist plots obtained from the EIS measurements and compare the equivalent circuit parameters calculated by LEBISDI with the corresponding original circuit parameters to assess the accuracy of the program developed. Calibration studies show that LEBISDI not only interpreted the simulated and circuit-element data accurately, but also successfully interpreted tissues impedance data and estimated the capacitive and resistive components produced by the compositions biological cells. Finally, LEBISDI efficiently calculated and analyzed variation in bioimpedance parameters of different tissue compositions, health and temperatures. LEBISDI can also be used for human tissue impedance analysis for electrical impedance-based tissue characterization, health analysis and disease diagnosis.

Vibration control of cantilever beam using Eddy Current Damper

This paper has investigated the ability to use the eddy current generated by magnetic field to suppress the vibration of cantilever beam. Eddy current systems have been employed in many applications such as in braking, transmission or damping system. For damping application the main advantage with respect to other devices is the possibility of working in absence of mechanical contact, eliminating wear problems and reducing the need of high accuracy alignment technique, typically required in mechanical damping system. In this paper finite element analysis (FEA) software was used in developing the model. First we have plotted various mode shapes of cantilever beam and then using a current carrying wire damped the vibration of cantilever beam Index term: Eddy current, cantilever beam, damping system, magnetic field. It is well established that, vibration theory is correlated with the modal parameters, namely frequency, damping, and mode shapes. These physical systems consist of the structure physical properties (mass, stiffness, and damping). These model parameters are the solutions of the homogeneous part of the differential equation of motion of a physical model expressed in terms of its mass, damping, stiffness, acceleration, velocity, and displacement. Consequently, any change in the physical properties of the model is directly proportional changes
Changes in Molecular Structure of Hemoglobin in Exposure to 50 Hz Magnetic Fields

The rapid development of new technological applications of static magnetic fields such as security systems, power plants and in medical practice as magnetic resonance imaging -MRI affects the human population. In certain occupations, clinical patients are exposed to over magnetic field strengths. The aim of this work is to elucidate the biological effect of short duration exposure, (one hour / day for a period of four consecutive days) to moderate and intense static magnetic field in the range of (0.5, 1.0 and 1.5T) which equivalent to that emitted from common sources of static magnetic field as (MRI) systems on the absorption spectra of hemoglobin (Hb) molecules and on its electric conductivity. In addition, the protein content and the electrophoresis mobility were measured for the plasma from the control and exposed albino rats, about 2 months age. The results indicated that, exposure of the animals to moderate and strong static magnetic fields resulted in changing in the absorption spectra and conductivity measurements of Hb molecules. Moreover, the total protein of the plasma increased and the electrophoretic mobilities also changed. It was concluded from the results that exposure to either diagnostic or interventional (MRI) may be hazardous for patients and more hazardous for machine operators.

Seasonal fluctuations of photosynthetic pigments content in Taxus baccata needles

Yew is a coniferous, evergreen, dioecious species. The objective of the study was to present a comprehensive characteristic of changes occurring throughout the year in terms of the content of photosynthetic pigments and related compounds in the needles of yew, depending on the sex of individuals and age of needles. Eight compounds, particularly chlorophyll a (Chl a), chlorophyll b (Chl b), carotenoids (Car), protoporphyrin IX (PPIX), magnesium protoporphyrin IX (MgPPIX), protochlorophyllide (Pchlide), chlorophyllide a (Chlide a), and chlorophyllide b (Chlide b), were subjected to quantitative analysis. Based on the several parameters under study, significant differences between male and female individuals were observed, while most commonly, the largest differences were reported in the autumn and winter period. They were related to the content of Chl a, Chl b and Chl/Car ratio. The remaining compounds showed no significant differences according to the sex and were slightly different only in single periods. For all the studied parameters except for Chl/Car ratio, interaction between sampling dates and sex was not statistically significant. Significant differences between the needles of different age were observed only in terms of the content of Chl b, MgPPIX, Pchlide, Chlide b, and Chl a/b ratio, and these differences were always caused by the current-year needles.
Looking Beyond Credit Ratings: Factors Investors Consider in Pricing European Asset‐Backed Securities

In this paper, we empirically investigate what credit factors investors rely upon when pricing the spread at issue for European asset-backed securities. More specifically, we investigate how credit factors affect new issuance spreads after taking into account credit rating. We do so by investigating primary market spreads for tranches of non-mortgage-related asset-backed securities issued from 1999 to the year prior to the subprime mortgage crisis, 2007. We find that although credit ratings play a major role in determining spreads, investors appear to not rely exclusively on these ratings. Our findings strongly suggest that investors do not ignore other credit factors beyond the assigned credit rating.

In the title coordination polymer, [Zn(C8H4O4)(C14H14N4)]n, the ZnII atom is coordinated by two N atoms from two 1,2-bis(imidazol-1-ylmethyl)benzene ligands as well as by the two O atoms from two terephthalate ligands, confering a tetrahedral coordination geometry. The bridging ligands generate a three-dimensional structure.
3 D Object-Oriented Learning : An End-to-end Transformation-Disentangled 3 D Representation by Qianli

We provide more detailed explanation of the ideas behind a recent paper on “Object-Oriented Deep Learning” [1] and extend it to handle 3D inputs/outputs. Similar to [1], every layer of the system takes in a list of “objects/symbols”, processes it and outputs another list of objects/symbols. In this report, the properties of the objects/symbols are extended to contain 3D information — including 3D orientations (i.e., rotation quaternion or yaw, pitch and roll) and one extra coordinate dimension (z-axis or depth). The resultant model is a novel end-to-end interpretable 3D representation that systematically factors out common 3D transformations such as translation and 3D rotation. As first proposed by [1] and discussed in more detail in [2], it offers a “symbolic disentanglement” solution to the problem of transformation invariance/equivariance. To demonstrate the effectiveness of the model, we show that it can achieve perfect performance on the task of 3D invariant recognition by training on one rotation of a 3D object and test it on 3D rotations (i.e., at arbitrary angles of yaw, pitch and roll). Furthermore, in a more realistic case where depth information is not given (similar to viewpoint invariant object recognition from 2D vision) our model generalizes reasonably well to novel viewpoints while ConvNets fail to generalize.

Multifunctional Curcumin-Nanocarriers Based on Host-Guest Interactionsfor Alzheimer Disease Diagnostic

The accumulation of amyloid peptides 40 and 42 in senile plaques is one of the hallmark lesions of Alzheimer Disease (AD). Great efforts are currently made to design molecules able to target these lesions in brain, both for diagnostic and therapeutic aims. Recent studies showed that curcumin has high affinity for the amyloid deposits. Curcumin is a fluorescent molecule with wide pharmaceutical activities, including potent anti-oxidant, anti-inflammatory, and anti-carcinogenic properties. Still, its low solubility limits its clinical and preclinical use. The use of controlled stoichiometric ratios between curcumin and host molecules like Methyl-β-cyclodextrin, para-sulphonato-calix(4)arene and para-sulphonato-calix(6)arene allowed the solubilisation of curcumin and the formation of stable nanocarriers. Within the nanocarriers, curcumin was available at their surfaces, being able to interact with the environment. They showed high affinity for the amyloid deposits, strongly labeling not only the senile plaques but also the diffuse deposits of Alzheimer Disease brains. Their biocompatibility was proved on several cell lines. Moreover, they were shown to interact with the Aβ peptide, reducing its aggregation and preventing its toxicity.

Characterization and Bioactivities of a Novel Exopolysaccharide Produced from Lactose by Bacillus tequilensis PS21 Isolated from Thai Milk Kefir

Kefir is a low cost fermented milk or sugary water product with several health benefits influenced by variable highly complex microbial consortia as well as metabolites such as organic acids, kefiran and other exopolysaccharides (EPSs) [1]. Microbial EPSs are biosynthetic polymers, mainly composed of carbohydrates secreted by bacteria [2], fungi [3] and cyanobacteria [4]. Exopolymers are categorized into two groups as (1) Heteropolysaccharides with high molecular mass consisting of numerous sugar monomers, synthesized by the orchestrated action of various glycosyl transferases, and (2) Homopolysaccharides that normally have lower molecular mass consisting of one sugar monomer synthesized by one or few glycosyl transferases [5]. The bioactivities of these microbial EPSs are not clearly understood, however they have typically been attributed to the presence of excessive numbers of different monomers, high hydrophobicity and a strong anionic nature [6]. The EPS content in kefir contributes to the organoleptic properties, texture and rheology of the finished product [7], and may also confer a wide range of bioactivities such as anti-inflammation, anticancer, antioxidant and antibacterial attributes. EPSs from Bacteroides fragiThe aims of this work were to characterize and determine bioactivities of crude exopolysaccharide (EPS) extract from Bacillus tequilensis PS21 isolated from milk kefir from Kampaeng Petch, Thailand. B. tequilensis PS21 produced 112.1 mg dried EPS/l from initial 80 g/l lactose in modified TSB media at 52 h, with EPS product yield of 8.9 mg EPS/g lactose and specific product yield of 0.3 mg EPS/mg biomass. The FTIR result confirmed EPS to be a protein-bound polysaccharide and SEM analysis showed the morphology to be a grainy appearance with an uneven surface, covered with pores. HPLC analysis determined EPS as a heteropolysaccharide consisting of five sugar units with the following molar ratios; xylose (17.65), glucose (2.54), ribose (1.83), rhamnose (1.23), and galactose (1). Chemical components of this EPS were predominantly carbohydrate at 697.8 mg/g EPS (65%), protein 361.4 mg/g EPS (34%), and nucleic acid 12.5 mg/g EPS (1%). The EPS demonstrated antioxidant activities at 57.5% DPPH scavenging activity, 37.2 μM Fe(II)/mg EPS and 34.9 μM TEAC μM/mg EPS using DPPH, FRAP and ABTS assays, respectively. EPS also exhibited anti-tyrosinase activity at 34.9% inhibition. This work represents the first finding of EPS produced by Bacillus sp. from Thai milk kefir which shows potential applications in the production of antioxidant functional foods and whitening cosmetics. However, optimization of EPS production for industrial exploitation requires further study to ascertain the economic potential.
Towards Optimal and Efficient Best Arm Identification in Linear Bandits

We give a new algorithm for best arm identification in linearly parameterised bandits in the fixed confidence setting. The algorithm generalises the well-known LUCB algorithm of Kalyanakrishnan et al. (2012) by playing an arm which minimises a suitable notion of geometric overlap of the statistical confidence set for the unknown parameter, and is fully adaptive and computationally efficient as compared to several state-of-the methods. We theoretically analyse the sample complexity of the algorithm for problems with two and three arms, showing optimality in many cases. Numerical results indicate favourable performance over other algorithms with which we compare.
Influence of food web structure on the growth and bioenergetics of lake trout (Salvelinus namaycush)

In this study, we compared energy budgets of lake trout (Salvelinus namaycush) populations in contrasting food webs. Nonpiscivorous lake trout (NPLT) reached a much smaller size and grew at a much slower rate than piscivorous lake trout (PLT) populations. Food consumption rates were, on average, 23 times higher in NPLT when they were expressed on a wet weight basis. However, only a slight (less than 10%) difference in their energy intake was detected once consumption rates were corrected for differences in prey caloric content. Growth efficiency was approximately two times lower in NPLT compared with PLT, while their metabolic costs were higher and their assimilation efficiency was lower. It is most likely that the increased metabolic costs were associated with higher foraging costs, since more feeding attempts must be made to acquire a given quantity of food when fish are feeding on smaller prey. Furthermore, the portion of indigestible matter is likely to be higher in the diet of NPLT than in PLT (i.e.
Response of Acacia tortilis to Elephant Browsing in Tarangire National Park, Tanzania: Possible Above-Ground Compensation?

keystone savanna species. There are many variables in woody savanna which affect the productivity of trees, including Acacia spp. Disease decreases growth, rainfall increases growth, and fire has variable effects on growth based on the severity of the fire and the characteristics of various Acacia species (Dharani et al., 2009; Fornara, 2008; Mopipi et al., 2009; Otieno, Kinyamario & Omenda, 2001; Scogings, Johansson, Hjalten & Kruger, 2012). However, effects of herbivory and the dynamic interactions between browsers and woody plants have been heavily disputed. Several researchers found that intense large herbivore browsing results in compensatory aboveground plant growth and can lead to alternative stable states (Dublin, Sinclair & McGlade, 1990; Jachmann & Bell, 1985; Smallie & O’Connor, 2000). However, others have found that large herbivore populations, such as elephants (Loxodonta africana) or giraffes (Giraffa camelopardalis), have a negative effect on woody vegetation growth (Guldemond & Van Aarde, 2008; Chira & Kinyamario, 2009; Pellew 1984). Past findings on the effects of browsing on sub-Saharan African Acacia species vary by mammal, tree species and response measurement. Browsing by non-elephant large mammals resulted in compensatory growth, leading to higher stem diameter growth of A. xanthophloea (Dharani et al., 2009). Similarly, simulated browsing of A. xanthophloea, A. tortilis, A. hockii (Pellew, 1984) and A. karroo (Stuart-Hill & Tainton, 1989) resulted in increased shoot growth and competitive ability when defoliation rates were between 25-50%. Du Toit, Bryant & Frisby (1990) and Chira & Kinyamario (2009) respectively found that heavy browsing by elephants led to an increase in shoot growth and higher nitrogen concentration in A. nigrescens foliage and coppice growth in A. INTRODUCTION Woody plants provide energy and nutrients for many mammals in African savannas. Throughout Africa, Acacia spp. trees provide the primary food source for numerous browsers, and also serve as important habitat for birds (Dharani, Kinyamario, Wagacha & Rodrigues, 2009). Many species, including black rhinoceros, giraffe, grey duiker, dik-dik, grysbok, klipspringer, gerenuk, dibatag, bushbuck, and kudu, feed exclusively on woody browse (OwenSmith, 1982). Because Acacia trees fix nitrogen, this also leads to higher forage quality in grasses underneath them compared to areas not under their canopies (Ludwig, De Kroon & Prins, 2008; Mopipi, Trollope & Scogings, 2009). Understanding the conditions that allow continued Acacia growth despite browsing will allow conservationists to monitor and prevent mortality of this Response of Acacia tortilis to Elephant Browsing in Tarangire National Park, Tanzania: Possible Above-Ground Compensation?
Emergent collective colloidal currents generated via exchange dynamics in a broken dimer state

Colloidal currents can be generated via a novel exchange mechanism based on combination of confinement and dipolar interactions. Controlling the flow of matter down to micrometer-scale confinement is of central importance in material and environmental sciences, with direct applications in nano and microfluidics, drug delivery, and biotechnology. Currents of microparticles are usually generated with external field gradients of different nature (e.g., electric, magnetic, optical, thermal, or chemical ones), which are difficult to control over spatially extended regions and samples. Here, we demonstrate a general strategy to assemble and transport polarizable microparticles in fluid media through combination of confinement and magnetic dipolar interactions. We use a homogeneous magnetic modulation to assemble dispersed particles into rotating dimeric state and frustrated binary lattices, and generate collective currents that arise from a novel, field-synchronized particle exchange process. These dynamic states are similar to cyclotron and skipping orbits in electronic and molecular systems, thus paving the way toward understanding and engineering similar processes at different length scales across condensed matter.
