description: Multiple instances of Zika virus epidemic have been reported around the world in the last two decades, turning the related illness into an international concern. In this context the use of mathematical models for epidemics is of great importance, since they are useful tools to study the underlying outbreak numbers and allow one to test the effectiveness of different strategies used to combat the associated diseases. This work deals with the development and calibration of an epidemic model to describe the 2016 outbreak of Zika virus in Brazil. A system of 8 differential equations with 8 parameters is employed to model the evolution of the infection through two populations. Nominal values for the model parameters are estimated from the literature. An inverse problem is formulated and solved by comparing the system response to real data from the outbreak. The calibrated results presents realistic parameters and returns reasonable descriptions, with the curve shape similar to the outbreak evolution and peak value close to the highest number of infected people during 2016. Considerations about the lack of data for some initial conditions are also made through an analysis over the response behavior according to their change in value.

description: Grayscale images are fundamental to many image processing applications like data compression, feature extraction, printing and tone mapping. However, some image information is lost when converting from color to grayscale. In this paper, we propose a light-weight and high-speed image decolorization method based on human perception of color temperatures. Chromatic aberration results from differential refraction of light depending on its wavelength. It causes some rays corresponding to cooler colors (like blue, green) to converge before the warmer colors (like red, orange). This phenomena creates a perception of warm colors "advancing" toward the eye, while the cool colors to be "receding" away. In this proposed color to gray conversion model, we implement a weighted blending function to combine red (perceived warm) and blue (perceived cool) channel. Our main contribution is threefold: First, we implement a high-speed color processing method using exact pixel by pixel processing, and we report a $5.7\times$ speed up when compared to other new algorithms. Second, our optimal color conversion method produces luminance in images that are comparable to other state of the art methods which we quantified using the objective metrics (E-score and C2G-SSIM) and a subjective user study. Third, we demonstrate that an effective luminance distribution can be achieved using our algorithm by using global and local tone mapping applications.

description: Stable and fast ionic conductors for magnesium cathode materials have the prospect of enabling high energy density batteries beyond current Lithium-ion technologies. So far, only a few candidate materials have been identified leading to data only being scarcely available to the community. Here, we present a systematic study, in the framework of Density Functional Theory, including the estimation of the diffusion barrier for 16 materials through employing Nudged Elastic Band (NEB) calculations. By introducing a path finder algorithm based on the idea of Voronoi tessellations, we show that an estimate of the transition state configuration can be extracted automatically prior to running NEB-calculations. Using geometrical descriptors in combination with a principal component analysis it is possible to further sub-group the diffusion paths. This approach also extends to materials which are not part of the study, making it a viable approach to more efficiently explore crystal structures with distinguishable diffusion characteristics.

description: We study the tetrad formulation of Chern-Simons (CS) modified gravity, which adds a Pontryagin term to the Einstein-Hilbert action with a spacetime-dependent coupling field. We first verify that CS modified gravity leads to a theory with torsion, where this tensor is given by an antisymmetric product of the Riemann tensor and derivatives of the CS coupling. We then calculate the torsion in the far field of a weakly gravitating source within the parameterized post-Newtonian formalism, and specialize the result to Earth. We find that CS torsion vanishes only if the coupling vanishes, thus generically leading to a modification of gyroscopic precession, irrespective of the coupling choice. Perhaps most interestingly, we couple fermions to CS modified gravity via the standard Dirac action and find that these further correct the torsion tensor. Such a correction leads to two new results: (i) a generic enhancement of CS modified gravity by the Dirac equation and axial fermion currents; (ii) a new two-fermion interactions, mediated by an axial current and the CS correction. We conclude with a discussion of the consequences of these results in particle detectors and realistic astrophysical systems.

title: Detection of Neonatal Calf Diarrhea Virus (NCDV) and Human Infant Reolike Diarrhea Virus
Creators: name: Peterson, Martin Wyatt
Publisher: name: Utah State University
Year: 1975

description: The purpose of this study was to develop a diagnostic test and conduct a survey for the neonatal calf diarrhea virus (NCDV) and human infant reolike diarrhea virus. Two immunologic methods were developed in this investigation.
Immune electron microscopy (IEM) and the fluorescent viral precipitin test (FVPT) are the methods used to detect NCDV and the human virus. Both methods are based upon the principle that viral aggregates form when the virus is reacted with anti-NCDV antibody. Aggregates in the IEM method are negatively stained and observed with the use of an electron microscope. Fluorescein labeled antibody is used in the FVPT and the resultant aggregates are observed with the use of epifluorescence microscopy.
IEM and the FVPT are sensitive, specific and rapid. The sample is examined within two hours after arriving at the laboratory. Both methods are useful; however, the FVPT allows for more general application because it requires less technical skill and relatively inexpensive equipment is used.
NCDV was found in 41% (14/34) of diarrheic calves tested in northern Utah and NCDV antibody was in 100% (16/16) of adult animals tested. The human reolike virus was found in 80% (4/5) of the infants tested.

description: The separation dimension of a hypergraph $G$ is the smallest natural number $d$ for which there is an embedding of $G$ into $\mathbb{R}^d$, such that any pair of disjoint edges is separated by some hyperplane normal to one of the axes. The perfect separation dimension further requires that any pair of disjoint edges is separated by the same amount of such (pairwise nonparallel) hyperplanes. While it is known that for any fixed $r \ge 2$, the separation dimension of any $n$-vertex $r$-graph is $O(\log n)$, the perfect separation dimension is much larger. In fact, no polynomial upper-bound for the perfect separation dimension of $r$-uniform hypergraphs is known. In our first result we essentially resolve the case $r=2$, i.e. graphs. We prove that the perfect separation dimension of $K_n$ is linear in $n$, up to a small polylogarithmic factor. In fact, we prove it is at least $n/2-1$ and at most $n(\log n)^{1+o(1)}$. Our second result proves that the perfect separation dimension of almost all graphs is also linear in $n$, up to a logarithmic factor. This follows as a special case of a more general result showing that the perfect separation dimension of the random graph $G(n,p)$ is w.h.p. $Ω(n p /\log n)$ for a wide range of values of $p$, including all constant $p$. Finally, we prove that significantly relaxing perfection to just requiring that any pair of disjoint edges of $K_n$ is separated the same number of times up to a difference of $c \log n$ for some absolute constant $c$, still requires the dimension to be $Ω(n)$. This is perhaps surprising as it is known that if we allow a difference of $7\log_2 n$, then the dimension reduces to $O(\log n)$.

description: This paper is an investigation of the stability of some ideal stars. It is in- tended as a study in General Relativity, with emphasis on the coupling to matter, eventually aimed at a better understanding of very strong gravitational fields and Black Holes. The work is based on an action principle for the complete system of metric and matter fields. We propose a complete revision of the treatment of boundary conditions. An ideal star in our terminology has spherical symmetry and an isentropic equation of state. In our first work on this subject it was assumed that the density vanishes beyond a finite distance from the origin. But it is difficult to decide what the proper boundary conditions should be and we are consequently skeptical of the concept of a fixed boundary. In this paper we investigate the double polytrope, characterized by a polytropic index n less than 5 in the bulk of the star and a value larger than 5 in an outer atmosphere that extends to infinity. It has no fixed boundary but a region of critical density where the polytropic index changes from a value that is appropriate for the bulk of the star to a value that provides a crude model for the atmosphere. The existence of a relation between mass and radius is confirmed, as well as an upper limit on the mass. The principal conclusion is that all the static configurations are stable.

title: The Effects of Age and Induction on Cockroach Mixed Function Oxidase Activity and Cell Morphology
Creators: name: Turnquist, Richard L.
Publisher: name: Utah State University
Year: 1972

description: Female American cockroaches showed definite age-dependent changes in levels of activity of the microsomal mixed function oxidase chain. Cytochrome P-450 levels, EPN-detoxication, and p-nitroanisole O-demethylation activities were very low in young adult insects but increased steadily reaching a peak at about 100 days in fat body and at about 90 days in midgut and hindgut. The activities then declined rapidly reaching levels of young insects at about 130 to 140 days of age. NADPH-NT-reductase activity was high in young insects and declined during the first few weeks of adult life. This activity too showed a peak at about 100 days.
Injections of chlorcyclizine, a known microsomal enzyme inducer, significantly increased levels of cytochrome P-450, EPN-detoxication, p-nitroanisole O-demethylation and NADPH-NT-reductase activities in young cockroaches. The inductive injections were effective, however, only before the natural activity peak was reached at 100 days. Beyond this point the injections had no inductive effect indicating that the microsomal mixed function oxidase chain in this insect is uninducible when normal enzyme levels are falling.
NADPH-NT-reductase activity in male cockroaches, while being somewhat higher than in females, showed a similar age-dependent curve with the peak occurring at about 120 days.
Age-dependent carbaryl resistance in male and female insects tended to follow levels of the mixed function oxidase activities. Fifty to sixty day old insects however, tended to be more resistant to the insecticide than microsomal enzyme levels would indicate.
RNA levels of normal female insects showed age-dependent curves similar to those of the microsomal enzyme activities being low in young adults and reaching a peak at about 100 days. Chlorcyclizine injections had little or no effect on total microsomal RNA levels. Surprisingly, actinomycin D, an RNA synthesis inhibitor, increased the inductive effect of chlorcyclizine at all ages.
Electron microscopy indicated that as enzyme levels increased the morphology of the endoplasmic reticulum changed. Tissue with low enzyme levels contained rough lamellar reticulum which became irregular or tubular in form as enzyme levels increased and finally became typical smooth reticulum in tissue with very high enzymatic activities. When enzyme levels began to fall the endoplasmic reticulum largely disappeared and concentric membrane whorls appeared in the cells. The whorls showed positive acid phosphatase activity. In older insects, which had low enzyme activities, rough lamellar endoplasmic reticulum was once again evident along with many large and very complex membrane whorls. The endoplasmic reticulum of induced tissue was characteristic of the enzyme levels attained in these insects. The ultrastructure of tissues with similar enzyme levels, whether normal or induced, tended to be very similar.

description: DP915635 maize was genetically modified (GM) to express the IPD079Ea protein for corn rootworm (Diabrotica spp.) control. DP915635 maize also expresses the phosphinothricin acetyltransferase (PAT) protein for tolerance to glufosinate herbicide and the phosphomannose isomerase (PMI) protein that was used as a selectable marker. A field study was conducted at ten sites in the United States and Canada during the 2019 growing season. Of the 11 agronomic endpoints that were evaluated, two of them (early stand count and days to flowering) were statistically significant compared with the control maize based on unadjusted p-values; however, these differences were not significant after FDR-adjustment of p-values. Composition analytes from DP915635 maize grain and forage (proximates, fiber, minerals, amino acids, fatty acids, vitamins, anti-nutrients, and secondary metabolites) were compared to non-GM near-isoline control maize (control maize) and non-GM commercial maize (reference maize). Statistically significant differences were observed for 7 of the 79 compositional analytes (16:1 palmitoleic acid, 18:0 stearic acid, 18:1 oleic acid, 18:2 linoleic acid, 24:0 lignoceric acid, methionine, and α-tocopherol); however, these differences were not significant after FDR-adjustment. Additionally, all of the values for composition analytes fell within the range of natural variation established from the in-study reference range, literature range, and/or tolerance interval. These results demonstrate that DP915635 is agronomically and compositionally comparable to non-GM maize represented by non-GM near-isoline control maize and non-GM commercial maize.
title: The Foraging Behavior of a Solitary Bee, Diadasia nigrifrons (Hymenoptera: Anthophoridae) on Sidalcea oregana, SSP. oregana
Creators: name: Kuta, Kimberly A.
Publisher: name: Utah State University
Year: 2003

description: Foraging studies have established that bees typically obey a set of movement rules when foraging on vertical inflorescences: they begin foraging at the bottom of an inflorescence, move upward, visit a fraction of the available flowers, and leave before reaching the top of the inflorescence. These behaviors are purported to maximize bee foraging efficiency by concentrating their efforts on the most rewarding flowers and minimizing flower revisits. Bees also increase their efficiency by selecting inflorescences with many flowers, visiting more flowers per inflorescence, and remaining in resource-rich areas. To test these hypotheses on plants with more complicated flower arrangements, I observed the foraging behavior of the solitary, specialist bee, Diadasia nigrifrons, on its host plant, Sidalcea oregana ssp. oregana, at two sites in northern Utah. S. oregana plants produce one to several paniculate (non-vertical) inflorescences. Flowers open from bottom to top within branches of the panicle, but flowering often occurs contemporaneously between branches
Diadasia foraging behavior did not conform to the expected movement rules. Bees tended to arrive at male flowers irrespective of their position on the inflorescence, visit one or a few flowers, and leave the inflorescence and the foraging area. They did not forage from bottom to top and did not appear to favor inflorescences with more flowers. Despite this, bees did respond to differences in flower number within inflorescences by visiting more flowers on larger inflorescences. Other studies have shown that bees tend to remain foraging in an area after encountering abundant resources. In addition to flower number as a measure of reward availability, I used the foraging time on the first flower visited and the time elapsed since the flower was last visited. The response of bees to these cues was inconsistent. Bees were not more likely to remain foraging in an area after visiting an inflorescence with many flowers than after visiting one with few flowers, nor were they consistently more likely to remain foraging after visiting rewarding flowers. I discuss several possible explanations for Diadasia's apparent non-optimal foraging behavior, including the possibility that Diadasia behavior is a response to perceived predation risks and/or reward availability.
title: Biphenyl Hydroxylation by Vole Hepatic Microsomes
Creators: name: Makary, Moheb H.
Publisher: name: Utah State University
Year: 1981

description: Metabolism of biphenyl by meadow voles (Microtus montanus) liver microsomes was studied by gas liquid chromatography. The microsomal biphenyl hydroxylation of Swiss Webster mice (outbred) was also investigated to provide a species comparison. 4-hydroxybiphenyl (major metabolite), 3-hydroxy biphenyl (minor) and smaller amounts of 2-hydroxybiphenyl were identified as metabolites of biphenyl incubated with vole liver microsomes. Liver microsomes from Swiss mice formed 4-hydroxy biphenyl (major metabolite) and almost equal amounts of 2- and 3-hydroxy biphenyl (minor metabolite). The amount of the hydroxy biphenyls formed by vole liver microsomes was considerably less per milligram of microsomal protein than for mice.
There was NADPH/NADH synergism with the formation of biphenyl hydroxylations in voles. Phenobarbital treatment of voles induced 2-, 3- and 4-hydroxy biphenyl formation, whereas only slight increases were observed after administration of 3-methylcholanthrene or B-naphthoflavone. No changes in the amount of biphenyl 2- hydroxylation of mice followed pretreatment with phenobarbital. However, 3-hydroxylation showed a small increase and 4-hydroxylation was induced. Mice pretreated with 3-methylcholanthrene or B-naphthoflavone were preferentially induced in biphenyl 2-hydroxylation. The reduced hemoprotein difference spectra of microsomal fractions were studied. Only 0.8 nm shift of the Soret peak occurred in liver microsomes from voles pretreated with, 3-methylcholanthrene. The induction and spectral data indicate that 2-, 3- and 4-hydroxylation are associated principally with cytochrome p-450 in voles with little evidence for a substantial role of cytochrome p-448. There is, therefore, a significant species difference between the hepatic microsomal mixed function oxidase system of meadow voles and white mice.

description: It is known that an identical delay in all transmission lines can destabilize macroscopic stationarity of a neural network, causing oscillation or chaos. We analyze the collective dynamics of a network whose intra-transmission delays are distributed in time. Here, a neuron is modeled as a discrete-time threshold element that responds in an all-or-nothing manner to a linear sum of signals that arrive after delays assigned to individual transmission lines. Even though transmission delays are distributed in time, a whole network exhibits a single collective oscillation with a period close to the average transmission delay. The collective oscillation can not only be a simple alternation of the consecutive firing and resting, but also nontrivially sequenced series of firing and resting, reverberating in a certain period of time. Moreover, the system dynamics can be made quasiperiodic or chaotic by changing the distribution of delays.

title: StatMod: A Tool for Interfacing ArcView® GIS with Statistical Software to Facilitate Predictive Ecological Modeling
Creators: name: Garrard, Christine M.
Publisher: name: Utah State University
Year: 2002

description: As geographical information systems and spatial data become more accessible, predictive spatial modeling in ecology is becoming more common. Unfortunately, not all ecologists possess the necessary skills to successfully combine statistical models and geographical information systems. In response to this problem, I wrote an extension for ArcView® GIS called StatMod. This extension interfaces ArcView GIS with SAS® and S-PLUS® statistical software and walks the user through creating and mapping logistic regression and classification and regression tree models.
StatMod was then used to run a series of analyses that would have been difficult without such a tool. A hypothetical density distribution for a nonexistent species was created, and then the effects of sample size and sampling regime on predictions of this density distribution were investigated. The effect of ground-truthed sample size on model accuracy estimates was also examined.
As expected, model accuracy generally improved as sample size increased. However, the majority of the improvement was seen as the sampled area approached one percent of the study area. Simple random sampling usually performed better than stratified random sampling, although the difference was most apparent when one density classification dominated the landscape. Estimates of model accuracy also improved as the number of ground-truthed sample points increased. Samples stratified by model predictions performed better than simple random samples at small sample sizes, although the reverse was true at large sample sizes. Again, this interaction was most apparent when one density classification dominated the landscape.

description: We report the preparation and readout of multielectron high-spin states, a three-electron quartet, and a four-electron quintet, in a gate-defined GaAs/AlGaAs single quantum dot using spin filtering by quantum Hall edge states coupled to the dot. The readout scheme consists of mapping from multielectron to two-electron spin states and a subsequent two-electron spin readout, thus obviating the need to resolve dense multielectron energy levels. Using this technique, we measure the relaxations of the high-spin states and find them to be an order of magnitude faster than those of low-spin states. Numerical calculations of spin relaxation rates using the exact diagonalization method agree with the experiment. The technique developed here offers a new tool for the study and application of high-spin states in quantum dots.

description: Three epochs of high resolution spectra of the star BD+20 307 show that it is a short period (~3.5 day) spectroscopic binary of two nearly identical stars. Surprisingly, the two stars, though differing in effective temperature by only ~250 K and having a mass ratio of 0.91, show very different Li line equivalent widths. A Li 6707 Angstrom line is only detected from the primary star, and it is weak. This star is therefore likely to be older than 1 Gyr. If so, the large amount of hot circumbinary dust must be from a very large and recent, but very late evolutionarily, collision of planetesimals.

Furthermore, we discuss how to build a controlled QKD scheme, also based on partially entangled states, where a third party can decide whether or not Alice and Bob are allowed to share a key.

description: We studied the absorption features of CO lines against the continuum originating from the heated dust in the obscuring tori around active galactic nuclei (AGNs). We investigated the formation of absorption lines corresponding to the CO rotational transitions using three-dimensional non-LTE line transfer simulations considering the dust thermal emission. As in Papers I--III of this series, we performed post-processed radiative transfer calculations using the "radiation-driven fountain model" (wada2016}, which yields a geometrically thick obscuring structure around the nucleus. This model is consistent with the spectral energy distribution of the nearest type-2 Seyfert galaxy, the Circinus galaxy. We found that the continuum-subtracted channel maps of $J = 4-3$ and higher transitions show absorption regions along the disk mid-plane for an edge-on viewing angle. The spectra consist of multiple absorption and emission features, reflecting the internal inhomogeneous and turbulent structure of the torus. The deepest absorption feature is caused by the gas on the near-side of the torus between $r =10$ and 15 pc, which is located in front of the AGN-heated dust inside $r \simeq 5$ pc. We also found that a spatial resolution of 0.5--1.0 pc is necessary to resolve the absorption features. Moreover, the inclination angle must be close to the edge-on angle (i.e., $\sim 85^\circ$) to observe the absorption features. The findings of the present study imply that combining our radiation-hydrodynamic model with high-resolution observations of CO (7-6) by ALMA can provide new information about the internal structure of the molecular tori in nearby AGNs.

description: This poster describes findings from the deep-sequencing (Illumina platform) of two cohorts with chronic hepatitis B virus (HBV) infection (CHB) from South Africa, one with hepatocellular carcinoma (HCC) and one with CHB only.
HBV genotypes A, D and E were identified in both cohorts. Data indicated that the viral diversity in patients with HCC was significantly higher than in the CHB cohort (p = 0.03). Indels were common in both patient groups, mostly occurring in the X-gene, core, and pre-S1/pol.

description: Gene technologies, such as transgenesis and new breeding techniques (NBTs), expand the toolbox for plant breeding. Many countries in Africa, however, have long been seen as “slow adopters” of gene technologies for several reasons, one being the lack of, or overly restrictive, biosafety regulatory frameworks. This is sometimes attributed to the influence of the precautionary-oriented EU biosafety policies. This study analyses and compares the biosafety regulatory frameworks and their implementation in Kenya, Nigeria and Uganda, and in the EU member state Sweden. The focus is on (1) the structure of the biosafety regulatory frameworks including the scope of the legislation, (2) the duration and cost of regulatory authorization for field trials with genetically modified (GM) plants, and (3) the regulatory approach to NBT products, i.e. to what extent NBT products are subject to the provisions of the biosafety regulatory framework. The data was collected through studying relevant legal and policy documents as well as interviewing regulatory officers and researchers in the respective countries. We found that the regulatory procedures in the selected countries are relatively straightforward, while the costs and duration may present a challenge. The regulatory approach to NBT products differ between the selected African countries and Sweden, the latter which follows EU regulations. The results are discussed in terms of the impact the regulatory developments in these four jurisdictions may have on international R&D collaborations involving the use of gene technologies and we also weigh the results against the common conception that Europe exerts a heavy influence on African countries in this technology field.

description: Database search has wide applications and is used as a subroutine in many important algorithms. We shall consider a database with one target item. Quantum algorithm finds the target item in a database faster than any classical algorithm. It frequently occurs in practice that only a portion of information about the target item is interesting, or we need to find a group of items sharing some common feature as the target item. This problem is in general formulated as search for a part of the database [a block] containing the target item, instead of the item itself. This is partial search. Partial search trades accuracy for speed, i.e. it works faster than a full search. Partial search algorithm was discovered by Grover and Radhakrishnan. We shall consider optimized version of the algorithm and call it GRK. It can be applied successively [in a sequence]. First the database is partitioned into blocks and we use GRK to find the target block. Then this target block is partitioned into sub-blocks and we use GRK again to find the target sub-block. [We can call it binary quantum search.] Another possibility is to partition the database into sub-blocks directly and use GRK to find the target sub-block in one time. In this paper we prove that the latter is faster [makes less queries to the oracle].

description: This work provides the basis to understand and select Cloud Computing models applied for the development of IoT solutions using Low-Power Wide Area Network (LPWAN). Cloud Computing paradigm has transformed how the industry implement solution, through the commoditization of shared IT infrastructures. The advent of massive Internet of Things (IoT) and related workloads brings new challenges to this scenario demanding malleable configurations where the resources are distributed closer to data sources. We introduce an analysis of existing solution architectures, along with an illustrative case from where we derive the lessons, challenges, and opportunities of combining these technologies for a new generation of Cloud-native solutions.

title: Alteration in Serum Enzyme Levels, Activity of Hepatic Monooxygenases, and Hepatocyte Morphology Due to Liver Enzyme Inducers in Microtus montanus
Creators: name: Hincks, Jeffery Roberts
Publisher: name: Utah State University

description: Microtus sp. have been used in microcosm simulations of polluted environments. In this study, female Microtus montanus (mountain vole), 8 - 12 weeks of age, were pretreated with phenobarbital (PB), ß-naphthoflavone (BNF), or Aroclor 1254 (PCB) for 3 consecutive days. Doses ranged from 5 to 80 mg/kg for each pretreatment, while control animals received saline or corn oil only. The voles were sacrificed 1 day after the last dose of PB and 2 days after BNF and PCB. Hepatic microsomal enzyme activity of aniline hydroxylase (AH), p-nitroanisole-O-demethylase (PNA) and cytochrome C reductase (CCR) were measured in relation to dose and type of inducer pretreatment. PB produced an induction for all 3 enzyme systems at the higher doses. Variation of PB dose from 5 to 80 mg/kg produced a biphasic effect in AH, PNA increased with each higher dose, and CCR showed a triphasic effect. BNF caused no significant change in AH activity, a biphasic response in PNA, and a triphasic effect in CCR with the highest activity at the 20 mg/kg dose. PCB demonstrated slight induction at low doses but higher doses produced no change or a decrease in enzyme activity. No increase in SGPT levels or serum malathion carboxylesterase occurred. Histological investigations revealed 2 morphological phases related to the type of induction. Low level induction showed foamy, vacuolated hepatocytes, while high induction produced very large, hypertrophied hepatocytes. A positive control for hepatic necrosis using 0.1 ml/kg carbon tetrachloride showed significant increases in serum enzymes and severe centrilobular and midzonal acute hepatic necrosis. Therefore, these results show a difference in induction potential of BNF and PCB compared to other rodents. Also, this study indicates the importance of inducer dose on the effect of hepatic monooxygenase activity.

description: We study theoretically the effects of heating on the magnetic flux moving in superconductors with a periodic array of pinning sites (PAPS). The voltage-current characteristic (VI-curve) of superconductors with a PAPS includes a region with negative differential resistivity (NDR) of S-type (i.e., S-shaped VI-curve), while the heating of the superconductor by moving flux lines produces NDR of N-type (i.e., with an N-shaped VI-curve). We analyze the instability of the uniform flux flow corresponding to different parts of the VI-curve with NDR. Especially, we focus on the appearance of the filamentary instability that corresponds to an S-type NDR, which is extremely unusual for superconductors. We argue that the simultaneous existence of NDR of both N- and S-type gives rise to the appearance of self-organized two-dimensional dynamical structures in the flux flow mode. We study the effect of the pinning site positional disorder on the NDR and show that moderate disorder does not change the predicted results, while strong disorder completely suppresses the S-type NDR.
