description: We present the analysis of the planetary nebula (PN) NGC 2371 around the [Wolf-Rayet] ([WR]) star WD 0722$+$295. Our Isaac Newton Telescope (INT) Intermediate Dispersion Spectrograph (IDS) spectra, in conjunction with archival optical and UV images, unveil in unprecedented detail the high-ionisation of NGC 2371. The nebula has an apparent multipolar morphology, with two pairs of lobes protruding from a barrel-like central cavity, a pair of dense low-ionisation knots misaligned with the symmetry axis embedded within the central cavity, and a high excitation halo mainly detected in He II. The abundances from the barrel-like central cavity and dense knots agree with abundance determinations for other PNe with [WR]-type CSPNe. We suggest that the densest knots inside NGC 2371 are the oldest structures, remnant of a dense equatorial structure, whilst the main nebular shell and outer lobes resulted from a latter ejection that ended the stellar evolution. The analysis of position-velocity diagrams produced from our high-quality spectra suggests that NGC 2371 has a bipolar shape with each lobe presenting a double-structure protruding from a barrel-like central region. The analysis of the spectra of WD 0722$+$295 results in similar stellar parameters as previously reported. We corroborate that the spectral sub-type corresponds with a [WO1] type.

description: We present results from two-dimensional numerical simulations of the interactions between magnetized shocks and radiative clouds. Our primary goal is to characterize the dynamical evolution of the shocked clouds. We perform runs in both the strong and weak magnetic field limits and consider three different field orientations. For the geometries considered, we generally find that magnetic fields external to, but concentrated near, the surface of the cloud suppress the growth of destructive hydrodynamic instabilities. External fields also increase the compression of the cloud by effectively acting as a confinement mechanism driven by the interstellar flow and local field stretching. This can have a dramatic effect on both the efficiency of radiative cooling, which tends to increase with increasing magnetic field strength, and on the size and distribution of condensed cooled fragments. In contrast, fields acting predominately internally to the cloud tend to resist compression, thereby inhibiting cooling. We observe that, even at modest strengths, internal fields can completely suppress low-temperature cooling.

description: A duality relation between the long-time dynamics of a quantum Brownian particle in a tilted ratchet potential and a driven dissipative tight-binding model is reported. It relates a situation of weak dissipation in one model to strong dissipation in the other one, and vice versa. We apply this duality relation to investigate transport and rectification in ratchet potentials: From the linear mobility we infer ground-state delocalization for weak dissipation. We report reversals induced by adiabatic driving and temperature in the ratchet current and its dependence on the potential shape.

description: The surface composition of S-type asteroids can be determined using band parameters extracted from their near-infrared (NIR) spectra (0.7-2.50 $μ$m) along with spectral calibrations derived from laboratory samples. In the past, these empirical equations have been obtained by combining NIR spectra of meteorite samples with information about their composition and mineral abundance. For these equations to give accurate results, the characteristics of the laboratory spectra they are derived from should be similar to those of asteroid spectral data (i.e., similar signal-to-noise ratio (S/N) and wavelength range). Here we present new spectral calibrations that can be used to determine the mineral composition of ordinary chondrite-like S-type asteroids. Contrary to previous work, the S/N of the ordinary chondrite spectra used in this study has been decreased to recreate the S/N typically observed among asteroid spectra, allowing us to obtain more realistic results. In addition, the new equations have been derived for five wavelength ranges encompassed between 0.7 and 2.50 $μ$m, making it possible to determine the composition of asteroids with incomplete data. The new spectral calibrations were tested using band parameters measured from the NIR spectrum of asteroid (25143) Itokawa, and comparing the results with laboratory measurements of the returned samples. We found that the spectrally derived olivine and pyroxene chemistry, which are given by the molar contents of fayalite (Fa) and ferrosilite (Fs), are in excellent agreement with the mean values measured from the samples (Fa$_{28.6\pm1.1}$ and Fs$_{23.1\pm2.2}$), with a maximum difference of 0.6 mol\% for Fa and 1.4 mol\% for Fs.

Self-duality, helicity and background field loopology
Creators: name: Dunne, Gerald V.

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: I show that helicity plays an important role in the development of rules for computing higher loop effective Lagrangians. Specifically, the two-loop Heisenberg-Euler effective Lagrangian in quantum electrodynamics is remarkably simple when the background field has definite helicity (i.e., is self-dual). Furthermore, the two-loop answer can be derived essentially algebraically, and is naturally expressed in terms of one-loop quantities. This represents a generalization of the familiar ``integration-by-parts'' rules for manipulating diagrams involving free propagators to the more complicated case where the propagators are those for scalars or spinors in the presence of a background field.

Framework for the characterization and performance projection of electrochemical capacitor electrodes
Creators: name: Fok, Chi Wah Eddie
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this thesis is to develop a framework for the characterization and performance projection of new electrochemical capacitor electrode materials. This framework was demonstrated on a new commercial electrode, called EXCELLERATOR®, from W.L. Gore & Associates, Inc. The electrode was tested in a Schlenk-type apparatus using cyclic voltammetry in a 0.5M tetrabutylammonium hexafluorophosphate in propylene carbonate solution. A macroscopic homogeneous volume averaged model was used to simulate the cyclic voltammetry response of the electrode. Subsequent fitting of the simulated response to the experimental data gave estimates of the volumetric capacitance and time constant of the electrode to be 40F/cm³ and 133.4s, respectively. Analytical solutions for the terminal voltage, energy density and power density were derived for the constant current discharging of a complete electrochemical capacitor. The evolution of the terminal voltage during discharge was explained. The energy and power densities for discharging the capacitor of different electrode thicknesses and at different current densities were investigated. The observed trends were explained by comparing the relative utilization of the electrode. The maximum energy density that can be extracted from an electrochemical capacitor during different lengths of time was simulated. It was shown that the thinner electrodes have higher energy and power densities at short times because of the lower unused active material mass. For long times, the thicker electrodes are superior because their active material mass is a larger fraction of the total mass. It was shown that the ultimate electrode geometry would involve thin electrodes with negligible non-active material masses. In this case, the thinnest electrodes would have higher energy and power densities than thicker ones even at long times.

description: In one dimensional chains of trapped Rydberg excitons in cuprous oxide semiconductor the topological spin phase has been recently predicted [Phys. Rev. Lett. 123, 126801 (2019); arXiv:1903.11951]. This phase is characterized by the diluted antiferromagnetic order of $p$-shell exciton angular momenta-$1$ and the edge states behaving akin spin-$1/2$ fermions. Here we study the properties of the ground state in the finite chains and its fine structure resulting from the effective interaction of the edge spins. We demonstrate that these edge states can detected optically via the enhancement of the circular polarization of the edge emission as compared with the emission from the bulk. We calculate the distribution of the exciton angular momentum vs. trap number in the chain numerically and analytically based on the variational ansatz.

description: LMC X-1, a persistent, rapidly rotating, extra-galactic, black hole X-ray binary (BHXB) discovered in 1969, has always been observed in its high soft state. Unlike many other BHXBs, the black hole mass, source distance and binary orbital inclination are well established. In this work, we report the results of simultaneous broadband spectral studies of LMC X-1 carried out using the data from Soft X-ray Telescope and Large Area X-ray Proportional Counter aboard AstroSat as observed on 2016 November 26$^{th}$ and 2017 August 28$^{th}$. The combined spectrum was modelled with a multicolour blackbody emission (diskbb), a Gaussian along with a Comptonization component (simpl) in the energy range 0.7$-$30.0 keV. The spectral analysis revealed that the source was in its high soft state ($Γ$=2.67$^{+0.24}_{-0.24}$ and $Γ$=2.12$^{+0.19}_{-0.20}$) with a hot disc (kT$_{in}$=0.86$^{+0.01}_{-0.01}$ and kT$_{in}$=0.87$^{+0.02}_{-0.02}$). Thermal disc emission was fit with a relativistic model (kerrbb) and spin of the black hole was estimated to be 0.93$^{+0.01}_{-0.01}$ and 0.93$^{+0.04}_{-0.03}$ (statistical errors) for the two Epochs through X-ray continuum-fitting, which agrees with the previous results.

description: Non-tachyonic superluminal sectors of matter (superbradyons), with critical speeds in vacuum much larger than the speed of light, can quite naturally exist and play an important role in both cosmic-ray physics (anomalous high-energy events) and cosmology (big-bang physics, alternatives to inflation, dark matter...). They can even be the real "elementary" particles. An updated discussion of the subject is presented, in relation with recent theoretical and experimental results. Prospects for future searches are also reexamined. Lorentz symmetry violation (LSV) models based on mixing with superbradyons are compared with LDRK (linearly deformed relativistic kinematics) and QDRK (quadratically deformed relativistic kinematics) such as defined in our previous paper physics/0003080 .

Equalization for DS-UWB systems
Creators: name: Parihar, Ambuj
Publisher: name: University of British Columbia
Year: 2010

description: Ultra-wideband wireless transmission has attracted considerable attention both in academia and industry. For high-rate transmission, direct sequence based ultra-wideband (DS-UWB) systems are a strong contender for standardization by the IEEE 802.15.3a Wireless Personal Area Networks (WPAN) committee. The DS-UWB proposal envisages two modulation formats: binary phase shift keying (BPSK) and 4-ary bi-orthogonal shift keying (4BOK). Due to the large transmission bandwidth, the UWB channel is characterized by a long root-mean- square delay spread and the RAKE receiver cannot always overcome the resulting intersymbol interference. We therefore study equalization for DS-UWB systems employing BPSK and 4BOK modulation. In the first part of this work, we consider equalization for DS-UWB with BPSK modulation, which is mandatory for standard-proposal compliant DS-UWB devices. Assuming RAKE preprocessing at the receiver, we analyze the performance limits applicable to any equalizer, taking into account practical constraints such as receiver filtering, sampling, and the number of RAKE fingers. Our results show that chip-rate sampling is sufficient for close-to-optimum performance. For analysis of suboptimum equalization strategies, we further study the distribution of the zeros of the channel transfer function including RAKE combining. Our findings suggest that linear equalization is well suited for the lower data rate modes of DS-UWB systems, whereas nonlinear equalization is required for high-data rate modes. Moreover, we devise equalization schemes with widely linear processing, which improves performance without increasing equalizer complexity. Simulation and numerical results confirm the significance of our analysis and equalizer designs and show that low-complexity (widely) linear and nonlinear equalizers perform close to the pertinent theoretical limit. In the second part, we investigate equalization for DS-UWB with 4BOK. To this end, we first derive expressions for the bit-error rate according to the matched-filter bound for 4BOK DS-UWB, which serve as theoretical performance limits for equalization. We then devise structures and methods for filter optimization for low-complexity linear and nonlinear equalization schemes. In this context, we develop a new equivalent multiple-input multiple-output (MIMO) description of 4BOK DS-UWB, which facilitates the design of efficient equalizers using MIMO filter optimization techniques. Furthermore, we propose the application of widely linear processing to these equalizers. Simulation and semi-analytical results show that (a) MIMO equalization is greatly advantageous over more obvious non- MIMO schemes, and (b) the proposed MIMO equalizers allow for power-efficient 4BOK DSUWB transmission close to the theoretical limits with moderate computational complexity.

description: We give preliminary results from a spectroscopic study of composite spectrum hot subdwarfs (sd+late-type). We obtained spectra of a sample of hot subdwarfs selected from the "Catalogue of Spectroscopically Identified Hot Subdwarfs" on the basis of near-infrared photometry from the Two Micron All Sky Survey (2MASS). The sample consists of 20 photometric and spectroscopic single and 54 composite hot subdwarfs, 6 resolved (or barely resolved) visual doubles, and 5 objects with emission lines or broad absorption lines with emission cores. Spectra of 84 "standard" (single late-type) stars with Hipparcos parallaxes were also obtained for calibration. These observations cover 4600-8900 Ang with 3 Ang resolution. We measured equivalent width-like indices around Mg I b, Na I D, the Ca II infrared triplet, H-alpha, and H-beta. Using the single late-type star observations combined with model energy distributions, we explore how the measured indices of a composite spectrum vary as the temperature and luminosity of the late-type companion are varied and as the temperature and radius of the hot subdwarf are varied. We use the measured indices of the composite systems to estimate the temperature and gravity of the late-type star, taking into account the dilution of its spectral features by light from the hot subdwarf.

description: The paper presented a short review of research on Total Factor Productivity (TFP) estimates at the global level and in the selected countries. Moreover, own study on TFP in the Polish farms during 2004-2012 based on FADN data was shown. The TFP measures were calculated for crops, milk, pigs and mixed farms using Cobb-Douglas’ regression models. We concluded that TFP for the Polish farms seems to be comparable to other farms, particularly to the EU-15 countries. Similarly to those countries the TFP measure for the milk farms was the highest. However, average annual reduction of TFP observed for some farm types in analysed period can give cause for concern. This reduction may result from fluctuations of agricultural productivity caused by the total economic situation, particularly in 2008-2009. Synopsis. W niniejszej pracy dokonano krótkiego przeglądu badań pokazujących szacunki wskaźnika całkowitej produktywności rolnictwa (Total Factor Productivity – TFP) w skali globalnej i w wybranych krajach. Zaprezentowano także wyniki własne, dotyczące analizy TFP w rolnictwie polskim w latach 2004-2012. Analizę wykonano w oparciu o dane rachunkowe gospodarstw rolnych z Polskiego FADN. Wskaźniki TFP policzono dla czterech typów gospodarstw rolnych, tj. polowych, mlecznych, trzodowych i mieszanych, na podstawie modeli regresji Cobb-Douglasa. Przeprowadzona analiza wykazała, że całkowita produktywność rolnictwa polskiego nie odbiega od krajów UE-15. Podobnie jak w tych krajach, polskie gospodarstwa mleczne charakteryzowały się najwyższym TFP. Niepokoi jednak średnioroczny spadek TFP w poszczególnych typach rolniczych w analizowanym okresie. Jest to głównie skutek znacznego obniżenia się produktywności w latach 2008-2009, co wiązało się z ogólną koniunkturą w tym okresie.

The changes in land use in Dutch floriculture sector, as well as in particular branches have been studied. The total acreage, number of farms, the average cultivation area and size structure of this area in each branch of the floriculture and land use structure have been analyzed, as well. The analyzes showed a significant changes as a response to changing macroeconomic circumstances. First of all, for the first time the decrease in the area under glass was visible, mainly with cut flower production. However, the acreage with nursery production continually was increasing. At the same time very deep drop in number of farms was observed, and the dynamic increase of an average size of plantation in 1 farm. / Synopisis.

Badano również zmiany w ilości gospodarstw i ich strukturze obszarowej. Z badań wynika, że w latach 2000-2011 nastąpiły w holenderskim kwiaciarstwie istotne zmiany, będące reakcją na zmieniające się uwarunkowania makroekonomiczne. Przede wszystkim po raz pierwszy obniżała się, i to wyraźnie, powierzchnia upraw szklarniowych, głównie kwiatów ciętych. Rosła natomiast w dalszym ciągu powierzchnia szkółek. Równocześnie bardzo szybko zmniejszała się liczba gospodarstw kwiaciarskich, rósł zaś dynamicznie średni areał plantacji w 1 gospodarstwie.

Public Economics

description: Excerpts from the article: Charging for public services is a revenue option that deserves more serious consideration in an era of rapidly escalating prices and budgetary cutbacks. Some local governments have recently reduced services and numbers of employees, but economic events in the eighties may force even larger cutbacks than anticipated. Although local public officials may not be able to avoid cutbacks, public pricing — charging the taxpayer a direct fee for public services rendered — is one revenue source with the potential for growth. What are the advantages and disadvantages of public pricing?

Neutrino-nucleus cross section in the impulse approximation regime
Creators: name: Benhar, Omar

Publisher: name: arXiv
Year: 2004
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: In the impulse approximation regime the nuclear response to a weakly interacting probe can be written in terms of the measured nucleon structure fuctions and the target spectral function, yielding the energy and momentum distribution of the constituent nucleons. We discuss a calculation of charged current neutrino-oxygen interactions in the quasielastic channel, carried out within nuclear many body theory. The proposed approach, extensively and successfully employed in the analysys of electron-nucleus scattering data, allows for a parameter free prediction of the neutrino-nucleus cross section, whose quantitative understanding will be critical to the analysis of the next genaration of high precision neutrino oscillation experiments.

description: [(SnSe)$_{1+δ}$]$_m$(NbSe$_2$) ($m$ = 1-6, 8, and 12) highly orientated crystals 1-2 mm in size and well-defined c-planes were successfully grown using CsCl/KCl flux, including the first growth of crystals with $m = 12$. The stacked layers along the $c$ axis in the obtained crystals were directly observed by transmission electron microscopy as m alternating layers of SnSe and single layers of NbSe$_2$. The superconducting transition temperature of the obtained [(SnSe)$_{1+δ}$]$_m$(NbSe$_2$) crystals decreased with an increase in the number of SnSe layers per unit cell. As the superconducting anisotropy parameters increase, a significant increase is observed between $m = 4$ and 5. This indicates that the superconducting dimensionality becomes more two-dimensional with an increasing $m$.

EJP SOIL SIMPLE D2.2 Higher fertilizers prices. The case of European Union, Sweden and Switzerland

description: This study analyzes how changes in fertilizer prices affect the consumption of fertilizers and agricultural production. We present three case studies: (1) the European Union (EU), (2) Sweden, and (3) Switzerland. For the EU case study, we rely on country-level data from 24 EU countries. For the Swedish case, we use regional-level data from 21 Swedish regions and for the Swiss case, we use the Information System of Structural Change in Switzerland/StrukturWandel InformationsSystem Schweiz (SWISSland) model.

The results of the EU case study show that EU farmers rely to a large extend on mineral nitrogen fertilizers, with no signs of gradual reduction as consumption fluctuates periodically over the past 22 years. Moreover, farmers' consumption is ‘inelastic’ to changes in fertilizer prices, indicating a strong dependency on mineral nitrogen fertilizers. However, the level of dependency can vary according to the geomorphological and climatic characteristics of the agricultural system. The Swedish case confirms the findings from the EU, with Swedish farmers exhibiting a similar relationship between fertilizer consumption and price changes. The results of the Switzerland case study show that projected changes in fertilizer prices do not significantly impact agricultural production, as fertilizer costs constitute only a small share of total farm costs. However, a substantial increase in fertilizer prices (e.g., a tenfold increase) does raise farming costs and subsequently impacts agricultural production.

Generating metal-polluting debris in white dwarf planetary systems from small-impact crater ejecta
Creators: name: Veras, Dimitri

Year: 2020

description: Metal pollution in white dwarf photospheres originates from the accretion of some combination of planets, moons, asteroids, comets, boulders, pebbles and dust. When large bodies reside in dynamically stagnant locations -- unable themselves to pollute nor even closely approach the white dwarf -- then smaller reservoirs of impact debris may become a complementary or the primary source of metal pollutants. Here, we take a first step towards exploring this possibility by computing limits on the recoil mass that escapes the gravitational pull of the target object following a single impact onto an atmosphere-less surface. By considering vertical impacts only with the full-chain analytical prescription from Kurosawa & Takada (2019), we provide lower bounds for the ejected mass for basalt, granite, iron and water-rich target objects across the radii range 10^{0-3} km. Our use of the full-chain prescription as opposed to physical experiments or hydrocode simulations allows us to quickly sample a wide range of parameter space appropriate to white dwarf planetary systems. Our numerical results could be used in future studies to constrain freshly-generated small debris reservoirs around white dwarfs given a particular planetary system architecture, bombardment history, and impact geometries.

Subjects: subject: Networking and Internet Architecture (cs.NI)
subject: FOS: Computer and information sciences

description: Decentralized applications (DApps), which are innovative blockchain-powered software systems designed to serve as the fundamental building blocks for the next generation of Internet services, have witnessed exponential growth in recent years. This paper thoroughly compares and analyzes two blockchain-based decentralized storage networks (DSNs), which are crucial foundations for DApp and blockchain ecosystems. The study examines their respective mechanisms for data persistence, strategies for enforcing data retention, and token economics. In addition to delving into technical details, the suitability of each storage solution for decentralized application development is assessed, taking into consideration network performance, storage costs, and existing use cases. By evaluating these factors, the paper aims to provide insights into the effectiveness of these technologies in supporting the desirable properties of truly decentralized blockchain applications. In conclusion, the findings of this research are discussed and synthesized, offering valuable perspectives on the capabilities of these technologies. It sheds light on their potential to facilitate the development of DApps and provides an understanding of the ongoing trends in blockchain development.

description: Quantum transport phenomena allow experimental assessment of the phase coherence information in metals. We report quantitative comparisons of coherence lengths inferred from weak localization magnetoresistance measurements and time-dependent universal conductance fluctuation data. We describe these two measurements and their analysis. Strong agreement is observed in both quasi-2D and quasi-1D AuPd samples, a metal known to have high spin-orbit scattering. However, quantitative {\it disagreement} is seen in quasi-1D Ag wires below 10 K, a material with intermediate spin-orbit scattering. We consider explanations of this discrepancy, with particular emphasis on the theoretical expressions used to analyze the field dependence of the conductance fluctuations. We also discuss the mechanism of the suppression of conductance fluctuations at high drive levels, and dephasing mechanisms at work in these systems.

description: We present a thorough phenomenological analysis of the experimental data from Belle Collaboration for the transverse $Λ$ and $\barΛ$ polarisation, measured in $e^+e^-$ annihilation processes, for the case of inclusive (plus a jet) and associated production with a light charged hadron. This allows for the first ever extraction of the quark polarising fragmentation function for a $Λ$ hyperon, a transverse momentum dependent distribution giving the probability that an unpolarised quark fragments into a transversely polarised spin-1/2 hadron.
