description: GipsyX/RTGx is the Jet Propulsion Laboratory's (JPL) next generation software package for positioning, navigation, timing, and Earth science using measurements from three geodetic techniques: Global Navigation Satellite Systems (GNSS), Satellite Laser Ranging (SLR), and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS); with Very Long Baseline Interferometry (VLBI) under development. The software facilitates combined estimation of geodetic and geophysical parameters using a Kalman filter approach on real or simulated data in both post-processing and in real-time. The estimated parameters include station coordinates and velocities, satellite orbits and clocks, Earth orientation, ionospheric and tropospheric delays. The software is also capable of full realization of a dynamic terrestrial reference through analysis and combination of time series of ground station coordinates. We present some key aspects of its new architecture, and describe some of its major applications, including Real-time orbit determination and ephemeris predictions in the U.S. Air Force Next Generation GPS Operational Control Segment (OCX), as well as in JPL's Global Differential GPS (GDGPS) System, supporting User Range Error (URE) of $

description: Tropical R is the birational map that intertwines products of geometric crystals and satisfies the Yang-Baxter equation. We show that the D^{(1)}_n tropical R introduced by the authors and its reduction to A^{(2)}_{2n-1} and C^{(1)}_n are equivalent to a system of bilinear difference equations of Hirota type. Associated tropical vertex models admit solutions in terms of tau functions of the BKP and DKP hierarchies.

title: Metascientific aspects of topoi of spaces
Creators: name: Melville, Charles Edwin Brian
Publisher: name: The Open University
Year: 1991

description: This thesis presents a study of the importance of topoi for Science. It is argued that whenever the concept of space enters the practice of Science then formal (mathematical) theories should be interpreted in a topos of spaces. It is claimed that these topoi encode knowledge of space arising directly out of the needs of Science, in that the constitutive questions of the Sciences can be traced back to their leading knowledge interests and these determine the role of mathematics as a methodical device. In the Natural Sciences the constitutive questions involve the study of non-intentional objects, in terms of a causal nexus to be explained geometrically, and this facilitates the introduction of geometric objects as the methodical device for posing questions to Nature. Although the study of intentional subjects in the Human Sciences requires ordinary language, not mathematics, to pose questions to each other, secondary methodological objectifications permit a conception of geometric objects analogous to that of the Natural Sciences. Lawvere*s axioms for the gros and petit topoi illustrate attempts to formalise the idea of topoi of spaces, as a rational reconstruction of categories in which geometric objects satisfying the formal theories of Science can be found. The catalysing function of this knowledge of topoi of spaces can lead to a diagnosis of mathematical difficulties caused by a failure to align mathematical conceptions with these topoi. This is illustrated through Varela's use of self-reference in Biology and Atkin's use of algebraic topology in Social Studies.

description: The structures of confining vortices which underlie pure SU(3) Yang-Mills theory are studied by means of lattice gauge theory. Vortices and Z_3 monopoles are defined as dynamical degrees of freedom of the Z_3 gauge theory which emerges by center gauge fixing and by subsequent center projection. It is observed for the first time for the case of SU(3) that these degrees of freedom are sensible in the continuum limit: the planar vortex density and the monopole density properly scales with the lattice spacing. By contrast to earlier findings concerning the gauge group SU(2), the effective vortex theory only reproduces 62% of the full string tension. On the other hand, however, the removal of the vortices from the lattice configurations yields ensembles with vanishing string tension. SU(3) vortex matter which originates from Laplacian center gauge fixing is also discussed. Although these vortices recover the full string tension, they lack a direct interpretation as physical degrees of freedom in the continuum limit.

description: In this paper we consider a system of two coupled nonlinear diffusion--reaction partial differential equations (PDEs) which model the growth of biofilm and consumption of the nutrient. At the scale of interest the biofilm density is subject to a pointwise constraint, thus the biofilm PDE is framed as a parabolic variational inequality. We derive rigorous error estimates for a finite element (FE) approximation to the coupled nonlinear system and confirm experimentally that the numerical approximation converges at the predicted rate. We also show simulations in which we track the free boundary in the domains which resemble the pore scale geometry and in which we test the different modeling assumptions.

Comparing Image Segmentation Algorithms

description: This paper presents a novel approach for denoising binary images using simulated annealing (SA), a global optimization technique that addresses the inherent challenges of non convex energy functions. Binary images are often corrupted by noise, necessitating effective restoration methods. We propose an energy function E(x, y) that captures the relationship between the noisy image y and the desired clean image x. Our algorithm combines simulated annealing with a localized optimization strategy to efficiently navigate the solution space, minimizing the energy function while maintaining computational efficiency. We evaluate the performance of the proposed method against traditional iterative conditional modes (ICM), employing a binary image with 10% pixel corruption as a test case. Experimental results demonstrate that the simulated annealing method achieves a significant restoration improvement, yielding a 99.19% agreement with the original image compared to 96.21% for ICM. Visual assessments reveal that simulated annealing effectively removes noise while preserving structural details, making it a promising approach for binary image denoising. This work contributes to the field of image processing by highlighting the advantages of incorporating global optimization techniques in restoration tasks.

description: The recurrent nova (RN) V3890 Sgr was observed during the 7th day after the onset of its most recent outburst, with the Chandra ACIS-S camera and High Energy Transmission Gratings (HETG). A rich emission line spectrum was detected, due to transitions of Fe-L and K-shell ions ranging from neon to iron. The measured absorbed flux is $\approx 10^{-10}$ erg cm$^{-2}$ s$^{-1}$ in the 1.4-15 Angstrom range (0.77-8.86 keV). The line profiles are asymmetric, blue-shifted and skewed towards the blue side, as if the ejecta moving towards us are less absorbed than the receding ones. The full width at half maximum of most emission lines is 1000-1200 km s$^{-1}$, with some extended blue wings. The spectrum is thermal and consistent with a plasma in collisional ionization equilibrium with column density 1.3 $\times 10^{22}$ cm$^{-2}$ and at least two components at temperatures of about 1 keV and 4 keV, possibly a forward and a reverse shock, or regions with differently mixed ejecta and red giant wind. The spectrum is remarkably similar to the symbiotic RNe V745 Sco and RS Oph, but we cannot distinguish whether the shocks occurred at a distance of few AU from the red giant, or near the giant's photosphere, in a high density medium containing only a small mass. The ratios of the flux in lines of aluminum, magnesium and neon relative to the flux in lines of silicon and iron probably indicate a carbon-oxygen white dwarf (CO WD).

description: In this work we study the performance of linear multifilters for the estimation of the amplitudes of the thermal and kinematic Sunyaev-Zel'dovich effects. We show that when both effects are present, estimation of these effects with standard matched multifilters is intrinsically biased. This bias is due to the fact that both signals have basically the same spatial profile. We find a new family of multifilters related to the matched multifilters that cancel this systematic bias, hence we call them Unbiased Matched Multifilters. We test the unbiased matched multifilters and compare them with the standard matched multifilters using simulations that reproduce the future Planck mission's observations. We find that in the case of the standard matched multifilters the systematic bias in the estimation of the kinematic Sunyaev-Zel'dovich effect can be very large, even greater than the statistical error bars. Unbiased matched multifilters cancel effectively this kind of bias. In concordance with other works in the literature, our results indicate that the sensitivity and resolution of Planck will not be enough to give reliable estimations of the kinematic Sunyaev-Zel'dovich of individual clusters. However, since the estimation with the unbiased matched multifilters is not intrinsically biased, it can be possible to use them to statistically study peculiar velocities in large scales using large sets of clusters.

description: Introduction
We investigated the effects of Kolop peloid on the clinical parameters and quality of life of patients with knee osteoarthritis in day hospital care.
Material and Method
We studied 60 patients randomized into two groups. Both groups received standardized combined physiotherapy and balneotherapy for the painful knee joint for three weeks, five days a week, including the following treatments: pool bath in 31°C mineral water for 30 minutes; aquatic exercise in 31°C mineral water pool bath for 20 minutes; and magnetotherapy applied on the knee joint. In addition, the peloid-treated group received Kolop peloid packs on the painful knee joint for 30 minutes at each session; the temperature of the pack was 42°C. The control group received standardized combined therapy on the knee joint without peloid packs. The disease-specific Western Ontario and McMaster Universities Arthritis Index (WOMAC), the EuroQol-5D quality of life questionnaire, the need for analgesics and NSAIDs, and the grade of periarticular tenderness were recorded before treatment, right after treatment (at Week 3), and 3 months after treatment (at Week 15).
Results
In patients treated with Kolop peloid, the clinical parameters (WOMAC pain, joint stiffness and function) improved more significantly from baseline to the end of treatment and to the end of the follow-up period than in the control group. Quality of life improved more in the Kolop peloid-treated group, and significant difference was seen between the two groups at the end of the follow-up period. Periarticular tenderness decreased more in the peloid group compared to the control group, although this difference was not significant.
Conclusion
The use of Kolop peloid in day hospital care is a possible therapeutic option in the treatment of patients with knee osteoarthritis.
title: A Structural and Biochemical Study of the Corneal Stroma
Creators: name: Wall, Rita Susan
Publisher: name: The Open University
Year: 1990

description: It is thought that the structural organisation of the cornea, in particular the uniform size and spacing of its constituent collagen fibrils, is a major factor responsible for its transparency. The roles of the various components of the corneal stroma in the maintenance of its structure are not currently well understood, although it is thought that proteoglycans an d the glyco-sylation of collagen may be involved in the control of fibril diameter. Protein components were removed from the corneal stroma, under mild and harsh conditions of extraction, and analysed using polyacrylamide gel electrophoresis and other biochemical techniques. A range of 0.15M NaCl- soluble proteins and proteoglycans could be removed under mild extraction conditions, including a proteoglycan of very high molecular weight which has not been reported elsewhere. Under harsh conditions of extraction, when 1% SDS was added to the extracting solution, an additional glyco¬protein, designated GP135, was removed. The effect of the extraction procedures on the structure of the cornea was studied using electron microscopy and X-ray diffraction. Electron mi¬croscopy showed increasing disruption to the ultrastructure of the cornea with more harsh extraction methods, and indicated that material had been removed from the gap region of the collagen fibrils. Loss of the interfibrillar X-ray diffraction pattern following extraction also indicated disruption of the ordered structure, and electron density profiles obtained from the meridional diffraction pattern suggested removal of material from the gap region. The coincidental removal of GP135 from the cornea with the removal of material from the gap region of the collagen fibrils indicated that it might be located here. Transparency measurements from extracted corneas showed that the loss of structural order produced by these methods might not be the most important factor in the loss of transparency for corneas at physiological hydration. Also, the transparency of highly h y d rated corneas is dependent on the type of solution they are immersed in.

description: This article will review recent results on dimensional reduction for branched polymers, and discuss implications for critical phenomena. Parisi and Sourlas argued in 1981 that branched polymers fall into the universality class of the Yang-Lee edge in two fewer dimensions. Brydges and I have proven in [math-ph/0107005] that the generating function for self-avoiding branched polymers in D+2 continuum dimensions is proportional to the pressure of the hard-core continuum gas at negative activity in D dimensions (which is in the Yang-Lee or $i ϕ^3$ class). I will describe how this equivalence arises from an underlying supersymmetry of the branched polymer model. - I will also use dimensional reduction to analyze the crossover of two-dimensional branched polymers to their mean-field limit, and to show that the scaling is given by an Airy function (the same as in [cond-mat/0107223]).

title: Novel asymmetric microenvironments for the separation of enantiomers of chiral drugs and natural products
Creators: name: Rimmer, Duncan Adam
Publisher: name: The Open University
Year: 1990

description: The determination of enantiomeric composition is of great importance in the pharmaceutical and natural product industries where two enantiomeric forms of a chiral molecule can have very different biological activities. Homochiral derivatization of enantiomeric compounds followed by chromatographic separation of the resultant diastereoisomers on conventional achiral columns has proved to be a cheap and useful method for enantioquantification. Reactions of simple alkyl halides with alcohols, acids, thiols and amines are known. Novel homochiral derivatization procedures based on two such reactions have been investigated. In these reactions, homochiral alkyl halide reagents, some of which are prepared here for the first time, have been based on proline and lactone ring systems and chiral esters. Another derivatization approach utilising highly reactive and novel homochiral chloromethyl ether reagents has proved successful. For example, racemic secondary alcohols when derivatized with (S)-(+)- tetrahydro-5-oxo-2-furanmethyl chloromethyl ether, have been separated to baseline. Quantification of 1% of one enantiomer in the presence of 99% of its antipode has been achieved. The presence of 5 bonds between the chiral centres of such diastereisomeric derivatives makes their separation an interesting result. Indeed, further work on the effects of spacing between chiral centres indicated that the separation efficiency of these systems were in the order 3>4<5 (bonds). An order of 3>4>5 is expected. The chloromethyl ether reagents, unlike the alkyl halides, do not have a proton on the atom P to the halide and thus cannot undergo dehydrohalogénation as a side reaction. The mild reaction conditions, employing diisopropylethylamine as a hindered non nucleophilic base make such derivatizations amenable to compounds containing acid and base sensitive functions. Assessment of the performances of both the alkyl halide and chloromethyl ether reagents are made by comparison with enantioseparations achieved when using N-acetyl-(S)-(-)-prolyl chloride and (+)-(trans)- chrysanthemoyl chloride reagents. Synthetic procedures for the preparation of all the homochiral reagents are reported. NMR techniques were investigated by employing modified cyclodextrins in an attempt to form diastereoisomeric inclusion complexes with chiral analytes. It was hoped that differences in their spectra would enable enantioquantification. Initial attempts at preparing novel homochiral polyesters by the condensation polymerisation of polyethylene glycol (400) with homochiral diacids were made. Such polymers may have use as homochiral chromatographic stationary phases.
Multi-scale time- and frequency-domain likelihood analysis with photon weights

description: We present an unbinned likelihood analysis formalism employing photon weights -- the probabilities that events are associated with a particular source. This approach is applicable to any photon-resolving instrument, and thus well suited to high-energy observations; we focus here on GeV $γ$-ray data from the Fermi Large Area Telescope. Weights connect individual photons to the outputs of a detailed, expensive likelihood analysis of a much larger data set. The weighted events can be aggregated into arbitrary time spans ranging from microseconds to years. Such retrospective grouping permits time- and frequency-domain analysis over a wide range of scales and enables characterization of disparate phenomena like blazar flares, $γ$-ray bursts, pulsar pulses, novae, $γ$-ray binaries, and other variable sources. To demonstrate the formalism, we incorporate photon weights into the Bayesian blocks algorithm and perform a hierarchical time scale analysis of 3C 279 activity. We analyze pulsar pulse profiles and estimate the unpulsed emission level and the optimal division of the data into on- and off-pulse intervals. We extend the formalism to Fourier analysis and derive estimators for power spectra, used to search for and characterize periodic sources. We show how the Fast Fourier transform can be used to probe orbital periods as short as a minute and we discuss mitigation of spurious signals. Our final example combines time- and frequency- domain analysis to jointly characterize the flares and orbital modulation of Cygnus X-3, yielding the strongest detection of the orbital signal ($>$13$σ$) to date. Finally, we discuss extensions of the work to other GeV sources and to X-ray and TeV observations.

description: This report summarizes the pesticide assessment for field corn and soybeans in the Corn Belt. Without insecticides, corn rootworm larvae and other soil insects would cause substantial corn yield losses, and Mexican bean beetles would reduce soybean yields. The loss of seed treatments would result in yield losses to both corn and soybeans. Among the herbicides, the loss of triazines would cause the greatest corn yield losses, while either dinitroanilines, acetanilides, or bentazon would cause the greatest soybean yield losses. This report includes pest rankings, estimates of acreages treated with pesticides or other pest management practices, and estimates of pest losses with and without pesticide use, for insects, diseases, nematodes, and weeds.

description: As a representative of a complex technological system, so-called wireless multihop ad hoc communication networks are discussed. They represent an infrastructure-less generalization of todays wireless cellular phone networks. Lacking a central control authority, the ad hoc nodes have to coordinate themselves such that the overall network performs in an optimal way. A performance indicator is the end-to-end throughput capacity. Various models, generating differing ad hoc network structure via differing transmission power assignments, are constructed and characterized. They serve as input for a generic data traffic simulation as well as some semi-analytic estimations. The latter reveal that due to the most-critical-node effect the end-to-end throughput capacity sensitively depends on the underlying network structure, resulting in differing scaling laws with respect to network size.

Methods: We observed the environment of the high-mass young stellar object IRAS11101-5829 and the closest knots of its jet, HH135-136, with the VLT/SINFONI. We also retrieved archival data from the high-resolution long-slit spectrograph VLT/X-shooter. Results: We detect the first three bandheads of the $\upsilon=2-0$ CO vibrational emission for the first time in this object. It is coincident with continuum and Br$γ$ emission and extends up to $\sim10000$ au to the north-east and $\sim10 000$ au to the south-west. The line profiles have been modelled as a Keplerian rotating disc assuming a single ring in LTE. The model output gives a temperature of $\sim3000$ K, a CO column density of $\sim1\times10^{22}\mathrm{ cm^{-2}}$, and a projected Keplerian velocity $v_\mathrm{K}\sin i_\mathrm{disc} \sim 25\mathrm{ km s^{-1}}$, which is consistent with previous modelling in other high-mass protostars. In particular, the low value of $v_\mathrm{K}\sin i_\mathrm{disc}$ suggests that the disc is observed almost face-on, whereas the well-constrained geometry of the jet imposes that the disc must be close to edge-on. This apparent discrepancy is interpreted as the CO seen reflected in the mirror of the outflow cavity wall. Conclusions: From both jet geometry and disc modelling, we conclude that all the CO emission is seen through reflection by the cavity walls and not directly. This result implies that in the case of highly embedded objects, as for many high-mass protostars, line profile modelling alone might be deceptive and the observed emission could affect the derived physical and geometrical properties; in particular the inclination of the system can be incorrectly interpreted.

description: This report summarizes the pesticide assessment for corn and soybeans in the Delta States. Without insecticides, corn rootworm larvae and other soil insects would cause substantial corn yield losses, while corn earworms or loopers would cause the greatest losses to soybeans. The loss of fungicides would result in corn yield losses from seed rots and seedling blights and soybean losses from foliar diseases. The loss of nematicides would cause soybean yield losses. Among the herbicides, the loss of triazines would cause the greatest corn yield losses, while either the phenoxys or bentazon would cause the greatest soybean yield losses. This report includes pest rankings, estimates of acreages treated with pesticides or other pest management practices, and estimates of pest losses with and without pesticide use, for insects, diseases, nematodes, and weeds.

description: We investigate the nonequilibrium spin polarization due to a temperature gradient in antiferromagnetic insulators, which is the magnonic analogue of the inverse spin-galvanic effect of electrons. We derive a linear response theory of a temperature-gradient-induced spin polarization for collinear and noncollinear antiferromagnets, which comprises both extrinsic and intrinsic contributions. We apply our theory to several noncentrosymmetric antiferromagnetic insulators, i.e., to a one-dimensional antiferromagnetic spin chain, a single layer of kagome noncollinear antiferromagnet, e.g., $\text{KFe}_3(\text{OH})_6(\text{SO}_4)_2$, and a noncollinear breathing pyrochlore antiferromagnet, e.g., LiGaCr$_4$O$_8$. The shapes of our numerically evaluated response tensors agree with those implied by the magnetic symmetry. Assuming a realistic temperature gradient of $10 \text{K}/\text{mm}$, we find two-dimensional spin densities of up to $\sim 10^6\hbar/\text{cm}^2$ and three-dimensional bulk spin densities of up to $\sim 10^{14}\hbar/\text{cm}^3$, encouraging an experimental detection.

description: This report summarizes the pesticide assessment for corn and soybeans in the Lake States. Without insecticides, corn rootworm larvae and other soil insects would cause substantial corn yield losses. The loss of seed treatments would result in yield losses to both corn and soybeans. Among the herbicides, the loss of tria— zines would cause the greatest corn yield losses, while the loss of dinitroani— lines would cause the greatest soybean yield losses. This report includes pest rankings, estimates of acreages treated with pesticides or other pest management practices, and estimates of pest losses with and without pesticide use, for insects, diseases, nematodes, and weeds.

description: We have used the PIBETA detector at the PSI for a precise measurement of rare pion and muon weak decays. We have collected a large statistical sample of (1) pi+ -> e+ nu, (2) pi+ -> pi0 e+ nu, (3) pi+ -> e+ nu gamma, (4) mu+ -> e+ nu nu, and (5) mu+ -> e+ nu nu gamma decays. We have evaluated the absolute branching ratios for these processes by normalizing to the independently measured number of decaying pi+'s (or mu+'s). We discuss the mutual consistency of the preliminary results.

Comparison of S=0 and S=1/2 Impurities in Haldane Chain Compound, $Y_{2}BaNiO_{5}$

description: We present the effect of Zn (S=0) and Cu (S=1/2) substitution at the Ni site of S=1 Haldane chain compound $Y_{2}BaNiO_{5}$. $^{89}$Y NMR allows us to measure the local magnetic susceptibility at different distances from the defects. The $^{89}$Y NMR spectrum consists of one central peak and several less intense satellite peaks. The shift of the central peak measures the uniform susceptibility, which displays a Haldane gap $Delta$$equiv$100 K and it corresponds to an AF coupling J$equiv$260 K between the near-neighbor Ni spins. Zn or Cu substitution does not affect the Haldane gap. The satellites, which are evenly distributed on the two sides of the central peak, probe the antiferromagnetic staggered magnetization near the substituted site, which decays exponentially. Its extension is found identical for both impurities and corresponds accurately to the correlation length $xi$(T) determined by Monte Carlo (QMC) simulations for the pure compound. In the case of non-magnetic Zn, the temperature dependence of the induced magnetization is consistent with a Curie law with an "effective" spin S=0.4 on each side of Zn, which is well accounted by Quantum Monte Carlo computations of the spinless-defect-induced magnetism. In the case of magnetic Cu, the similarity of the induced magnetism to the Zn case implies a weak coupling of the Cu spin to the nearest- neighbor Ni spins. The slight reductionin the induced polarization with respect to Zn is reproduced by QMC computations by considering an antiferromagnetic coupling of strength J'=0.1-0.2 J between the S=1/2 Cu-spin and nearest-neighbor Ni-spin.

Stochastic Schrodinger equations as limit of discrete filtering

description: We consider an open model possessing a Markovian quantum stochastic limit and derive the limit stochastic Schrodinger equations for the wave function conditioned on indirect observations using only the von Neumann projection postulate. We show that the diffusion (Gaussian) situation is universal as a result of the central limit theorem with the quantum jump (Poissonian) situation being an exceptional case. It is shown that, starting from the correponding limiting open systems dynamics, the theory of quantum filtering leads to the same equations, therefore establishing consistency of the quantum stochastic approach for limiting Markovian models.

description: This report summarizes the pesticide assessment for corn and soybeans in the Northeast. Without insecticides, cutworms would cause the greatest corn yield losses and Mexican bean beetles the greatest soybean yield losses. Seed rots and seedling blights would cause substantial corn yield losses without pesticide control, while nematodes would reduce soybean yields. Among the herbicides, the loss of triazines would cause the greatest corn yield losses and acetanilides the greatest soybean losses. This report includes pest rankings, estimates of acreages treated with pesticides or other pest management practices, and estimates of pest losses with and without pesticide use, for insects, diseases, nematodes, and weeds.

description: We use molecular dynamics simulations to study the melting of gold icosahedral clusters of a few thousand atoms. We pay particular attention to the behavior of surface atoms, and to the equilibrium shape of the cluster. We find that although the surface of the cluster remains ordered up to the melting T_m, the increasing mobility of vertex and edge atoms significantly soften the surface structure, leading to inter- and intra-layer diffusion, and shrinking of the average facet size, so that the average shape of the cluster is nearly spherical at melting.
