description: We study theoretically the effects of qubit inhomogeneity on the quantum logic gate of qubit swap, which is an integral part of the operations of a quantum computer. Our focus here is to construct a robust pulse sequence for swap operation in the simultaneous presence of Zeeman inhomogeneity for quantum dot trapped electron spins and the finite-time ramp-up of exchange coupling in a double dot. We first present a geometric explanation of spin swap operation, mapping the two-qubit operation onto a single-qubit rotation. We then show that in this geometric picture a square-pulse-sequence can be easily designed to perform swap in the presence of Zeeman inhomogeneity. Finally, we investigate how finite ramp-up times for the exchange coupling $J$ negatively affect the performance of the swap gate sequence, and show how to correct the problems numerically.

description: Germination and hydroponic experiments are performed on rice seeds growing in soils treated with Cd stress, with rice seeds of the same variety that is not treated with Cd stress as a control, to study the effects of Cd stress on quality of rice seeds. The results have shown that: (1) Cd stress reduces the thousand grain weight of rice seeds, and higher Cd content means lower thousand grain weight; (2) The germination vigor and germination percentage of rice seeds under Cd stress as well as their α-amylase activity and β-amylase activity are all lower than those of the control. They decreases as the Cd stress increases; (3) For rice seeds under Cd stress, the height, fresh and dry weight of seedlings, as well as the chlorophyll content, photosynthetic rate and content of soluble protein of their leaves are all lower than those of the control. This indicates that Cd stress has certain effects on the germination and growth of the rice seeds.

subject: Uzbekistan

description: Given the importance of healthy diet and especially the adequate intake of fruit and vegetables, the current state of inefficient agricultural production in Uzbekistan has serious adverse consequences on the yields of fruit and vegetables, and thus on income of such farmers (mostly, dehkan farms and households), and would raise the prices paid by consumers of such food products, especially in off season. The impact of higher food prices would have the most significant effect on the poorest rural people for whom the necessity of healthy food consumption is of major importance due to the poor nutritional status. The purpose of this research is, therefore, to investigate the effects of improved fruit/vegetable availability and accessibility on demand and public health in Uzbekistan. In addition, potential and existing constraints and opportunities to improve the availability and accessibility of fruit and vegetables as a key determinant of healthy diet will be explored.

description: In this paper, we fully investigate cosmological scenarios in which dark matter is non-minimally coupled to an extra scalar degree of freedom. The interaction is realized by means of conformal and disformal terms in the transformed gravitational metric. Considering linear perturbation theory, we show that the growth rate of dark matter differs from the uncoupled case and that the well-known Kaiser formula undergoes modification. As a result, redshift space distortion measurements cease to be a direct probe of the linear growth rate of total matter, since the distortion factor has an extra, coupling-dependent term. We study the effect of the coupling in three cosmological models, two conformally and one disformally coupled, and forecast the constraints on the coupling, and other cosmological parameters, from future galaxy surveys.

description: Using N-body simulations of the Large Magellanic Cloud (LMC's) passage through the Milky Way (MW), tailored to reproduce observed kinematic properties of both galaxies, we show that the high-speed tail of the Solar Neighborhood dark matter distribution is overwhelmingly of LMC origin. Two populations contribute at high speeds: 1) Particles that were once bound to the LMC, and 2) MW halo particles that have been accelerated owing to the response of the halo to the recent passage of the LMC. These particles reach speeds of 700-900 km/s with respect to the Earth, above the local escape speed of the MW. The high-speed particles follow trajectories similar to the Solar reflex motion, with peak velocities reached in June. For low-mass dark matter, these high-speed particles can dominate the signal in direct-detection experiments, extending the reach of the experiments to lower mass and elastic scattering cross sections even with existing data sets. Our study shows that even non-disrupted MW satellite galaxies can leave a significant dark-matter footprint in the Solar Neighborhood.

title: Demonstration and Optimization of the Chemical Looping Gasification Technology in 1 MWth Scale
Creators: name: Dieringer, Paul
Publisher: name: UNSPECIFIED
Year: 2024

description: Chemical looping gasification (CLG) is a novel thermochemical process allowing for the efficient conversion of different feedstocks (e.g. biomass, municipal waste) into a high-calorific synthesis gas (=H2 & CO), which can subsequently be used for the synthesis of different marketable products, such as fuels or chemicals. While the CLG technology was successfully validated in lab scale using different reactor setups, feedstocks, and active materials, its demonstration in an industrially relevant environment remains a challenge. Overcoming this major technical hurdle on the pathway towards advancing the CLG technology to market maturity, thereby facilitating an efficient valorization of different waste streams in the future, signifies the main goal of this dissertation. To accomplish this, the existing 1 MWth pilot plant at the Institute for Energy Systems and Technology (EST) was adapted and optimized in order to allow for long-term autothermal (i.e. without external energy input) chemical looping gasification. Here, the general steps of a standardized chemical engineering project, ranging from process definition and basic engineering to plant commissioning, operation, and optimization, were carried out between March 2019 and September 2023.
In the course of this venture, the general viability of autothermal chemical looping gasification in an industrially relevant environment was proven by ultimately achieving over 400 hours of CLG operation in the 1 MWth pilot plant, utilizing three different biogenic materials as feedstock. This was facilitated by devising a novel process control concept as well as a holistic set of operational rules and principles, allowing for efficient autothermal CLG operation, with cold gas efficiencies up to 50 % being reached in 1 MWth scale. On top of that, crucial findings for establishing a suitable process layout of an industrial-scale chemical looping gasifier were derived in the course of the adaption and commissioning of the 1 MWth pilot plant as well as the subsequent in-depth evaluation of the datasets gathered during autothermal CLG operation. Moreover, this evaluation allowed for a holistic investigation of relevant aspects for process up-scaling, covering the most auspicious routes for process optimization as well as potential technical bottlenecks one could encounter in industrial scale. Process simulations, using models validated with data gathered during autothermal CLG operation, show that when overcoming the technical hurdles faced in 1 MWth scale, such as limited oxygen carrier (OC) lifetime and restricted OC circulation, cold gas efficiencies >80 % and carbon conversions close to 90 % can be obtained in industrial scale. Hence, the technical competitiveness of the chemical looping gasification process was demonstrated within the scope of this work, thus encouraging future up-scaling activities, which could promote the CLG technology into a crucial building block for the aspired circular economy.

description: Raspberries are one of very important agricultural products of the Republic of Serbia and this production offers a lot of possibilities for employment in rural areas. Therefore, the goal of this paper is to analyze various aspects of economic efficiency and financial feasibility of investments in establishment of raspberry plantations. Models of investments in raspberry plantations are formed using real technological, organizational and economical conditions at rural households. These investment models considered different dynamics of investments in raspberry plantations. Besides, there were assumed various financing conditions for these investments. For evaluation of economic efficiency of the investments are used appropriate capital budgeting methods – net present value, modified internal rate of return and payback period. The analysis proved that establishment of raspberry plantations is economically efficient for both assumed dynamics of investments. It is economically more acceptable to establish raspberry plantation simultaneously on the entire available surface intended for that purpose, than to do it gradually. It is also determined that investments will be financially feasible if participation of borrowed funds in structure of financial sources is less than 41.07%.

 Note: the sexes are broadly similar in colour pattern, both being variable in ground colour, although the males are less so. Most males are bright orange, but some are more olivaceous – as in f. ‘ brunnea ’ Eltringham, which occurs in both sexes. Females are rarely as orange as males. Female form ‘ emini ’ Weymer is slightly more obscure than ‘ brunnea ’; the whitish ‘ auasa ’ Gabriel, which seems only known from Ethiopia, is in overall coloration similar to the whitish females of A. pseudolycia pseudolycia from western and central Africa.

description: While the Republic of Serbia is increasingly moving towards EU integration, and while one of the many EU requirements is the yearly transmission of the accountancy data that are important for the annual determination of the incomes of agricultural holdings and analysis of their business operation, the need to establish and develop Serbian Farm Accountancy Data Network (FADN) system becomes a crucial strategic option. This research paper describes how this requirement has been fulfilled for the Republic of Serbia, with special focus on FADN institutional framework. In this paper it is used unique replicable European Union (EU) methodology that has been applied and adjusted in accordance with national conditions. Furthermore, a comparative research method was used in a particular area of this study, which aimed to make comparisons across different FADN institutional framework of certain EU member states and Republic of Serbia. The results of this research paper showed that the FADN institutional frameworks in EU member states as well as institutional framework of the Republic of Serbia as candidate country have been established on the same bases, such as accountancy data collection–processing–transmission chain. However, the FADN institutional frameworks in EU member states are different and complex. Furthermore, taking into consideration comparison of the current state of FADN institutional framework in certain EU member states and Republic of Serbia, this paper demonstrated that although currently there is no specific sub-legal act, that prescribes the functioning of the FADN system in Serbia, there is a dynamic phase at an early stage of the Serbian FADN institutional framework development. Evidently, it is in development and needs to be further improved and strengthened while the sub-legal act, that prescribes the functioning of the FADN system, needs to be adopted. Consequently, for completed Serbian FADN system establishment and its sustainable development and functioning, there are still many challenges to overcome.

description: In this paper we examine the effects of energy prices on groundwater extraction using an econometric model of a farmer’s irrigation water pumping decision that accounts for both the intensive and extensive margins. Our results show that energy prices have an important effect on both the intensive and extensive margin. Increasing energy prices would affect crop selection decisions, crop acreage allocation decisions, and the demand for water by farmers. Our estimated total marginal effect, which sums the effects at the intensive and extensive margins, is that an increase in the natural gas futures contract price of 1 cent/1000 btu would decrease water extraction by an individual framer by 102.88 acre-feet per year, which is approximately 63% of the average amount pumped in a year by a farmer.

description: We studied transboundary ground water management problems in the presence of hydraulic fracturing (fracking). We found that the presence of risk suggests a need to exercise caution in fracking. We also found that a cooperative outcome implies the decrease in fracking and the increase in steady state survival rate of groundwater. However, water extraction rates remained the same in both cooperative and noncooperative solutions. We also argue that a Pigouvian type tax could be imposed on the natural gas developers.

description: In this paper, new fluorescence assay was developed for ethylmorphine based on complex formation with terbium. Ethylmorphine is an opiate and it is prone to be abused. Therefore, it is one of the frequently tested analytes in screening tests. The developed assay can be used as a screening test for opiate alkaloids since it produces fluorescence ON response with a simple experiment, and it may be used for an alternative/additional test to avoid false negative/positive results in regular screening tests. The assay can also be used for the quantitative analysis of ethylmorphine.

description: To meet the growing demand for freshwater, many regions have increased pumping of groundwater in recent years, resulting in declining groundwater levels worldwide. A promising development is technical change regarding groundwater substitutes such as desalination and wastewater recycling. However, because these technologies are energy intensive, optimal implementation also depends on future energy price trends. We provide an operational model for the application to reverse-osmosis seawater desalination. With this foundation, we outline a research agenda for extending the framework to other groundwater substitutes and for adaptation to climate change.

description: We introduce a tracking-by-detection method that integrates a deep object detector with a particle filter tracker under the regularization framework where the tracked object is represented by a sparse dictionary. A novel observation model which establishes consensus between the detector and tracker is formulated that enables us to update the dictionary with the guidance of the deep detector. This yields an efficient representation of the object appearance through the video sequence hence improves robustness to occlusion and pose changes. Moreover we propose a new state vector consisting of translation, rotation, scaling and shearing parameters that allows tracking the deformed object bounding boxes hence significantly increases robustness to scale changes. Numerical results reported on challenging VOT2016 and VOT2018 benchmarking data sets demonstrate that the introduced tracker, L1DPF-M, achieves comparable robustness on both data sets while it outperforms state-of-the-art trackers on both data sets where the improvement achieved in success rate at IoU-th=0.5 is 11% and 9%, respectively.

Non-collinear magnetism in iron at high pressures

description: Using a first principles based, magnetic tight-binding total energy model, the magnetization energy and moments are computed for various ordered spin configurations in the high pressure polymorphs of iron (fcc, or $γ$-Fe, and hcp, or $ε$-Fe), as well ferromagnetic bcc iron ($α$-Fe). For hcp, a non-collinear, antiferromagnetic, spin configuration that minimizes unfavorable ferromagnetic nearest neighbor ordering is the lowest energy state and is more stable than non-magnetic $ε$ iron up to about 75 GPa. Accounting for non-collinear magnetism yields better agreement with the experimental equation of state, in contrast to the non-magnetic equation of state, which is in poor agreement with experiment below 50 GPa.

 Forewing length: male 25.0 – 32.0 mm [mean (n = 26) 28.44 mm, SD = 1.418]; female 30.0 – 35.5 mm [mean (n = 16) 32.41 mm, SD = 1.205].
 Note: It is widely said that this species is reliably separable from the next (A. encedon) only by examination of the genitalia (and early stages). Pierre and Bernaud (2014) recognise five morphs of A. encedana; as with the more numerous morphs of A. encedon, all show individual variation, and apparently occur in both sexes. Larsen (1996, p. 363), however, stated that A. encedana has a ‘ deeper orange ground colour, and the postdiscal black spots on the hindwing underside which are closer to the [discal] cell ’. Examination of material in OUMNH identified by Jacques Pierre suggests that the ground colour character is helpful, but probably not the supposed hindwing spot pattern difference. Larsen (1996, 2005, p. 447) also suggested that encedana is larger than encedon (our forewing length data are consistent, but the sample mean values are quite small, with considerable overlap), and is generally restricted to open, marshy habitats. Bernaud (2000) indicates that in West Africa, at least, encedana can be found on mountains above 1500 m, whereas encedon does not exceed that altitude. The larval foodplants differ radically (encedon on Commelina, encedana on Desmodium), as does the coloration of larvae and pupae.

description: Recent increases in farm real estate values in the U.S. have increased farm equity in the form of unrealized capital gains. Exploiting periods of high and low appreciation that caused different increases in wealth for farmers owning different shares of their farmland, we examine if U.S. grain farmers expanded their acres harvested or acres owned in response to an increase in their land wealth. We find that land wealth had little effect on farm size. However, for farms of a similar size, owning 10 percentage points more land increased the growth rate of land owned by 2 percentage points. Because older farmers own a larger share of the land in the farm, an increase in the rate of land appreciation slows the rate at which younger farmers acquire land relative to older farmers.

description: Turbulence can significantly accelerate the growth of dust grains by accretion of molecules. For dust dynamically coupled to the gas, the growth rate scales with the square of the Mach number, which means that the growth timescale can easily be reduced by more than an order of magnitude. The limiting timescale is therefore rather the rate of molecular cloud formation, which means that dust production in the ISM can rapidly reach the levels needed to explain the dust masses observed at high redshifts. Thus, turbulence may be the solution to the replenishment problem in models of dust evolution in high-redshift galaxies and explain the dust masses seen at $z = 7 - 8$. A simple analytic galactic dust-evolution model is presented, where grain growth nicely compensates for the expected higher rate of dust destruction by supernova shocks. This model is simpler, relies on fewer assumptions and seems to yields a better fit to data derived from observations, compared to previous models of the same type.

description: Many real-world networks exhibit scale-free feature, have a small diameter and a high clustering tendency. We have studied the properties of a growing network, which has all these features, in which an incoming node is connected to its $i$th predecessor of degree $k_i$ with a link of length $\ell$ using a probability proportional to $k^β_i \ell^α$. For $α> -0.5$, the network is scale free at $β= 1$ with the degree distribution $P(k) \propto k^{-γ}$ and $γ= 3.0$ as in the Barabási-Albert model ($α=0, β=1$). We find a phase boundary in the $α-β$ plane along which the network is scale-free. Interestingly, we find scale-free behaviour even for $β> 1$ for $α< -0.5$ where the existence of a new universality class is indicated from the behaviour of the degree distribution and the clustering coefficients. The network has a small diameter in the entire scale-free region. The clustering coefficients emulate the behaviour of most real networks for increasing negative values of $α$ on the phase boundary.

description: Neutron diffraction studies have been carried out on a single crystal of oxygen-deficient perovskite TbBaCo2O5.5 in the temperature range of 7-370 K. There have been observed several magnetic or structural transitions. Among these, the existence of the transitions to the insulating phase from the metallic one at ~340 K, to the one with the ferromagnetic moment at ~280 K and possibly to the antiferromagnetic one at ~260 K, with decreasing temperature T correspond to those reported in former works. We have studied the magnetic structures at 270 K and 250 K and found that all Co3+ ions of the CoO6 octahedra are in the low spin state and those of the CoO5 pyramids carry spins which are possibly in the intermediate spin state. Non-collinear magnetic structures are proposed at these temperatures. Two other transitions have also been observed at the temperatures, ~100 K and ~250 K.

 Larsen 1996: pl. 52, fig. 650i. d ’ Abrera 1997: 165 (4 figs). Bernaud and Murphy 2014: 110 (8 figs, Malawi). SI: Figure 23a – j.
 Forewing length: male 24.0 – 31.5 mm [mean (n = 15) 27.48 mm, SD = 1.797]; female 28.0 – 35.5 mm [mean (n = 16) 31.04 mm, SD = 1.377].
 Note: Although this appears to be slightly smaller (see also SI Table 1), as indicated above, critical separation from the sibling species A. encedana depends, in the adult, on examination of the genitalia (both sexes: Pierre 1976). Pierre and Bernaud (2014) appear to recognise up to a dozen morphs, all of which probably occur in both sexes (the sexes are difficult to separate on coloration alone).

description: A periodic network of connected rhombii, mimicking a spintronic device, is shown to exhibit an intriguing spin selective extreme localization, when submerged in a uniform out of plane electric field. The topological Aharonov Casher phase acquired by a travelling spin is seen to induce a complete caging, triggered at a special strength of the spin orbit coupling, for half odd integer spins s \ge n\hbar/2, with n odd, sparing the integer spins. The observation finds exciting experimental parallels in recent literature on caged, extreme localized modes in analogous photonic lattices. Our results are exact.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present XMM-Newton X-ray spectra and optical photometry of four high redshift (z=2.96-3.77) quasars, [HB89] 0438-436, [HB89] 2000-330, [SP89] 1107+487 and RX J122135.6+280613; of these four objects the former two are radio-loud, the latter two radio-quiet. Model fits require only a power law with Galactic absorption in each case; additional intrinsic absorption is also needed for [HB89] 0438-436 and RX J122135.6+280613. The spectra are hard (Gamma \~1.7 for [HB89] 0438-436, [HB89] 2000-330 and ~1.4 for RX J122135.6+280613) with the exception of [SP89]~1107+487 which is softer (Gamma ~2.0); the combined Galactic and intrinsic absorption of lower energy X-rays in the latter source is much less significant than in the other three. The two intrinsically unabsorbed sources have greater optical fluxes relative to the X-ray contributions at the observed energies. While there is no need to include reflection or iron line components in the models, our derived upper limits (99% confidence) on these parameters are not stringent; the absence of these features, if confirmed, may be explained in terms of the high power law contribution and/or a potentially lower albedo due to the low disc temperature. However, we note that the power-law spectrum can be produced via mechanisms other than the Comptonization of accretion disc emission by a corona; given that all four of these quasars are radio sources at some level we should also consider the possibility that the X-ray emission originates, at least partially, in a jet.

Conductance of a molecular junction mediated by unconventional metal-induced gap states

description: The conductance of a molecular junction is commonly determined by either charge-transfer-doping, where alignment of the Fermi energy to the molecular levels is achieved, or tunnelling through the tails of molecular resonances within the highest-occupied and lowest-unoccupied molecular-orbital gap. Here, we present an alternative mechanism where electron transport is dominated by electrode surface states. They give rise to metallization of the molecular bridge and additional, pronounced conductance resonances allowing for substantial tailoring of its electronic properties via, e.g. a gate voltage. This is demonstrated in a field-effect geometry of a fullerene-bridge between two metallic carbon nanotubes.

description: We introduce a spherical version of the frustrated Blume-Emery-Griffiths model and solve exactly the statics and the Langevin dynamics for zero particle-particle coupling (K=0). In this case the model exhibits an equilibrium transition from a disordered to a spin glass phase which is always continuous for nonzero temperature. The same phase diagram results from the study of the dynamics. Furthermore, we notice the existence of a nonequilibrium time regime in a region of the disordered phase, characterized by aging as occurs in the spin glass phase. Due to a finite equilibration time, the system displays in this region the pattern of interrupted aging.

description: Animal welfare is a major concern for consumers. This concern has not gone unnoticed by sector stakeholders, especially egg producers. One of the fundamental changes likely to affect egg producers regards modes of production, specifically changes in housing systems, ranging from conventional cages to free range. From farmers’ perspective, changing their mode of production generates a technological and economic/marketing risk. This study documents the level of risk in the Canadian egg sector (conventional and specialty eggs) using data from 2009 to 2011. Our results indicate multiple uncertainty sources (technological, cost of production, price of eggs) that vary according to the types of eggs. We use a quadratic programming approach applied to expected mean-variance models to analyze the impact of risk on decision to invest when the resources must be allocated to different types of production that have different risk levels. Overall our results show how, given risk aversion parameters, producers minimize their risk levels by devoting their resources to the least risky type of eggs. An important result of our study is that supply management, by reducing the perceived risk level, has favored the development of specialty eggs, for the benefit of consumers.
