description: Biofuels and other forms of bioenergy have received increased attention in recent times: They have partly been acclaimed as an instrument to contribute to rural development, energy security and to fight global warming but have been increasingly come under attack for their potential to contribute to rising food prices. It has thus become clear that bioenergy cannot be evaluated independently of the rest of the economy and that national and international feedback effects are important. In this paper we describe how the CGE model DART is extended to include first-generation biofuel production technologies. DART can now be used to assess the efficiency of combined climate and bioenergy policies. As a first example the effects of a 10% biofuel target in the EU are analyzed.

description: This paper mainly focuses on the various ways through which a social cash transfer program can be designed and financed. We identify four types of households which are considered to be vulnerable to be targeted with cash transfers. This includes households with orphans, old individuals, young and labor constrained. Extending a cash transfer to these households would lead to less poverty over the simulation period. these programs which would be constrained to less than 0.5 percent of GDP would have a small impact on the overall economy. By increasing taxes to finance the program this would wipe out the potential benefits of the cash transfer program of reducing poverty.

description: Chemical equilibrium has proven extremely useful to predict the chemical composition of AGB atmospheres. Here we use a recently developed code and an updated thermochemical database, including gaseous and condensed species involving 34 elements, to compute the chemical equilibrium composition of AGB atmospheres of M-, S-, and C-type stars. We include for the first time TixCy clusters, with x = 1-4 and y = 1-4, and selected larger clusters ranging up to Ti13C22, for which thermochemical data is obtained from quantum chemical calculations. We find that in general chemical equilibrium reproduces well the observed abundances of parent molecules in circumstellar envelopes of AGB stars. There are however severe discrepancies, of various orders of magnitude, for some parent molecules: HCN, CS, NH3, and SO2 in M-type stars, H2O and NH3 in S-type stars, and the hydrides H2O, NH3, SiH4, and PH3 in C-type stars. Several molecules not yet observed in AGB atmospheres, like SiC5, SiNH, SiCl, PS, HBO, and the metal-containing molecules MgS, CaS, CaOH, CaCl, CaF, ScO, ZrO, VO, FeS, CoH, and NiS, are good candidates for detection with observatories like ALMA. The first condensates predicted are carbon, TiC, and SiC in C-rich atmospheres and Al2O3 in O-rich outflows. The most probable gas-phase precursors of dust are acetylene, atomic carbon, and/or C3 for carbon dust, SiC2 and Si2C for SiC dust, and atomic Al and AlOH, AlO, and Al2O for Al2O3 dust. In the case of TiC dust, atomic Ti is probably the main supplier of titanium. However, chemical equilibrium predicts that clusters like Ti8C12 and Ti13C22 become the major reservoirs of titanium at the expense of atomic Ti in the region where condensation of TiC is expected to occur, suggesting that the assembly of large TixCy clusters could be related to the formation of the first condensation nuclei of TiC.

Metafore del meccanico nel pensiero di Diderot. Arti e tecniche

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2014

description: The natural philosophy of Diderot is built from the experience of the fundamental Description des Arts in the Encyclopedia, or from the «great and beautiful collection of machines» which the work provides a very rich representation. Models and metaphors that Diderot constructs to describe the world of organic beings, from the Pensées sur l'Interpretation de la nature (1753), are inspired by the world of the mechanical arts and crafts. The manouvriers d’expériences, the experimental philosophers, are the great inventors and discoverers of the secrets of nature and living being: to them Diderot inspire itself and his work as a philosopher of nature and arts. From the loom to weave socks, to the fire pump, the description of the machine proceeds through a complex network of metaphors that combine the operation of the instrument to that of organic life. The machine energises itself and the organism, in turn, is mechanized in a maze of functional architectures, according to new models and artistic metaphors of living beings, other than cartesian one. Diderot does not cease to be mechanistic still in his last vitalistic works, from Le Rêve de D’Alembert, to the Éléments de Physiologie. The new world of handicraft and artisans remains the key reference point in the philosophical work of the encyclopaedist-naturalist: weaving loom socks and sensible harpsichord are the two tools / metaphors that describe the man and his rational and specific nature.

Panama • 5.4 mm • 1 ♀; Bocas del Toro, Chiriqui Grande, Laguna de Chiriqui; 8.9396°N, 82.1105°W; depth 0.2–1.5 m, among Thalassia; 10 Aug 2005; S. LeCroy leg.; GCRL 6661.
Diagnosis.
Head ocular lobe posteriorly upturned; rostrum slightly produced. Antenna 1 flagellum 6 - articulate. Pleopod 2 outer ramus unsegmented; inner ramus with marginal plumose setae. Uropod 1 outer ramus wide, apical margin not narrowing distally; inner ramus with apical robust seta, distal margin of seta narrowing unevenly.

Ecology and remarks.
This species occurs among Thalassia at depths of 0.2–1.5 m. This species can be difficult to identify with only female specimens. Previously, male specimens have been identified based on the following characteristics: coxa 3 with small anterior lobe, reaching body lengths longer than most Cerapus species, ranging from 4–13 mm, male pereon segment 1 with lateral keel, male gnathopod 2 basis, anterodorsal margin with numerous, long setae, antennae 1 and 2, 7–12 segmented (LeCroy 2007; Thomas and Heard 1979). The number of antennae segments seems variable based on size, as seen with the specimens described herein and by Drumm (2018). Panamanian specimens agree closely with the original description of Cerapus benthophilus Thomas & Heard, 1979. Ethanol-preserved specimens retained purple coloration on most of the body, especially on the head.

description: Trajectory generation is an important task in movement studies; it circumvents the privacy, ethical, and technical challenges of collecting real trajectories from the target population. In particular, real trajectories in the wildlife domain are scarce as a result of ethical and environmental constraints of the collection process. In this paper, we consider the problem of generating long-horizon trajectories, akin to wildlife migration, based on a small set of real samples. We propose a hierarchical approach to learn the global movement characteristics of the real dataset and recursively refine localized regions. Our solution, WildGraph, discretizes the geographic path into a prototype network of H3 (https://www.uber.com/blog/h3/) regions and leverages a recurrent variational auto-encoder to probabilistically generate paths over the regions, based on occupancy. WildGraph successfully generates realistic months-long trajectories using a sample size as small as 60. Experiments performed on two wildlife migration datasets demonstrate that our proposed method improves the generalization of the generated trajectories in comparison to existing work while achieving superior or comparable performance in several benchmark metrics. Our code is published on the following repository: https://github.com/aliwister/wildgraph.

Metafore della natura e natura della metafora in Denis Diderot
Creators: name: Messori, Rita
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2014

description: The writings of Diderot, even the most philosophical, are characterized by a poetic style, by the frequent use of figures of speech, especially metaphor. The metaphorical images like, the "great chain of being", the "swarm of bees" and the "sensitive harpsichord", are an expression of experimental philosophy that proceeds by "presentiments", by intuitions and not by concepts. The philosopher, from the experience of natural phenomena, forms an idea, though vague, of nature as a dynamic unity of parts, as the order in the making. Standing at the intersection of philosophy, poetics and life sciences, the metaphor suggests an image of the organic unity of nature and the human body, the continuous and gradual metamorphosis of every natural being.

description: The paper presents an empirical analysis of money demand in Uganda over the period 1986:1-2003:4. Two definition of money were used and tests for co-integration between the monetary aggregates and real money balance were carried out. The empirical results show that income is positively related to money demand while exchange rate, inflation and interest rates have a negative impact on money demand and there is a degree of substitution from non-interest to interest bearing financial assets and holding of foreign currency. the money demand functions remained stables for the entire period, as confirmed by the chow tests.
Fundamental aspects of gold leaching in thiosulfate solutions
Creators: name: Li, Cheng
Publisher: name: University of British Columbia
Year: 2009

description: The kinetics and mechanism of gold leaching in the ammonia-thiosulfate-copper (ATS-Cu) system have been studied using the rotating electrochemical quartz crystal microbalance (REQCM). Anodic polarization, cathodic polarization and leaching experiments were included in this study. The effect of concentration of different reagents, applied potential, pH, temperature, and electrode rotating velocity on the gold leaching rate have been investigated. The effect of solution copper species on the anodic reaction of gold dissolution in thiosulfate solution was elucidated using the REQCM. With respect to the role of copper on the anodic processes, two possible mechanisms were proposed. It was shown that, in the absence of S₂O₃²⁻, the electrochemical reaction on the cathode is the reduction of Cu(NH₃)₄²⁺+ to Cu(NH₃)₂⁺ in the potential range of 0.2 to -0.3 V vs. SHE. Based on other experimental results, it is believed that, in the presence of S₂O₃²⁻, the electrochemical reaction on the cathode also is the same as the reaction in the absence of S₂O₃²⁻. It was found that the anodic process and leaching process are under chemical reaction control, but the cathodic process is under diffusion control. It may therefore be concluded that the leaching process is under anodic control under the majority of conditions tested (cathodic control will be important when the cupric ammine species is very dilute in solution). Experiments show that increasing the ratio of NH3/ S₂O₃²⁻ will favor the leaching rate. However, excess thiosulfate or excess ammonia may inhibit the dissolution of gold. The effect of selected additives was also studied.

description: A semi-classical non-Hamiltonian model of a spontaneous collapse of unstable quantum system is given. The time evolution of the system becomes non-Hamiltonian at random instants of transition of pure states to reduced ones, given by a contraction C. The counting trajectories are assumed to satisfy the Poisson law. A unitary dilation of the concractive stochastic dynamics is found. In particular, in the limit of frequent detection corresponding to the large number limit we obtain the Ito-Schroedinger stochastic unitary evolution for the pure state of unstable quantum system providing a new stochastic version of the quantum Zeno effect.

description: It has been argues that increased aid causes Dutch disease as a result of appreciation of the exchange rate which reduces the competitiveness of the country's exports. In this paper, we argue that if the aid is used productively, there are both short and long term gains. Applying a recursive dynamic general equilibrium model on Uganda, we find that while the currency appreciates and some exports decline, the overall impact on growth outweighs the losses in competitiveness. In addition, it aid is used productively, poverty would be substantially reduced as long as the aid increase is sustained.
The Textual Ecology of the Palimpsest: Environmental Entanglement of Present and Past

description: Utilizing the metaphor of the palimpsest, this paper looks at layering processes at work in the natural world and human perceptions of it, paying particular attention to the manifestations of the past visible in constructions in and of the landscape. History is made of constant reformations, in which pieces of the past make up the present. The palimpsest offers a useful tool for discussing a trans-temporal landscape. The layers of landscape construction go beyond the literal geological construction, encompassing human pasts and presents as well. Engaging the palimpsestuous layers at work in physical and textual landscape construction allows us to place human endeavours into more expansive notions of temporality.

Novel Joint Estimation and Decoding Metrics for Short-Block length Transmission Systems

Year: 2024
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: This paper presents Bit-Interleaved Coded Modulation metrics for joint estimation detection using training or reference signal transmission strategies for short to long block length channels. We show that it is possible to enhance the performance and sensitivity through joint detection-estimation compared to standard receivers, especially when the channel state information is unknown and the density of the training dimensions is low. The performance analysis makes use of a full 5G transmitter and receiver chains for both Polar and LDPC coded transmissions paired with BPSK/QPSK modulation schemes. We consider transmissions where reference signals are interleaved with data and both are transmitted over a small number of OFDM symbols so that near-perfect channel estimation cannot be achieved. This is particularly adapted to mini-slot transmissions for ultra-reliable, low-latency communications (URLLC) or for short packet random access use cases. We characterize the performance for up to eight receiving antennas in order to determine the performance gain offered by the proposed BICM detection in realistic base station receiver scenarios. Our findings demonstrate that when the detection windows used in the metric units is on the order of four modulated symbols the proposed BICM metrics can be used to achieve detection performance that is close to that of a coherent receiver with perfect channel state information for both polar and LDPC coded configurations. Furthermore, we show that for transmissions with low DMRS density, a good trade-off can be achieved in terms of additional coding gain and improved channel estimation quality by adaptive DMRS power adjustment.

description: Wavelets are a new and powerful mathematical tool, whose most celebrated applications are data compression and de-noising. In Paper I (Romeo, Horellou & Bergh 2003, astro-ph/0302343), we have shown that wavelets can be used for removing noise efficiently from cosmological, galaxy and plasma N-body simulations. The expected two-orders-of-magnitude higher performance means, in terms of the well-known Moore's law, an advance of more than one decade in the future. In this paper, we describe a wavelet add-on code designed for such an application. Our code can be included in common grid-based N-body codes, is written in Fortran, is portable and available on request from the first author. The code can also be applied for removing noise from standard data, such as signals and images.

description: the paper examines the gender dimensions of personal income tax (PIT) in Uganda with an eye on the possible gender biases that may be embedded in the tax system. It further addresses the issues of Uganda achievement of substantive gender equality rather than formal equality as regards the impact of taxes from a gender perspective. This is in line with Convention on the elimination of all forms of discrimination against all people as if they are the same and synonymous with equality of opportunity... we find that PIT paid by different household earning types increases gender inequality. We also find that some tax systems only worsens gender gaps and hardly is a useful tool that could be used to close the gender gaps. This paper proposes how PIT could be reformed with a view to using taxation as a tool for the realization of substantive gender equality.

A Non-Stationary Bandit-Learning Approach to Energy-Efficient Femto-Caching with Rateless-Coded Transmission

description: The ever-increasing demand for media streaming together with limited backhaul capacity renders developing efficient file-delivery methods imperative. One such method is femto-caching, which, despite its great potential, imposes several challenges such as efficient resource management. We study a resource allocation problem for joint caching and transmission in small cell networks, where the system operates in two consecutive phases: (i) cache placement, and (ii) joint file- and transmit power selection followed by broadcasting. We define the utility of every small base station in terms of the number of successful reconstructions per unit of transmission power. We then formulate the problem as to select a file from the cache together with a transmission power level for every broadcast round so that the accumulated utility over the horizon is maximized. The former problem boils down to a stochastic knapsack problem, and we cast the latter as a multi-armed bandit problem. We develop a solution to each problem and provide theoretical and numerical evaluations. In contrast to the state-of-the-art research, the proposed approach is especially suitable for networks with time-variant statistical properties. Moreover, it is applicable and operates well even when no initial information about the statistical characteristics of the random parameters such as file popularity and channel quality is available.

description: The purpose of this study was to quantitatively evaluate the visibility and artifacts of commercially available fiducial markers in order to optimize their selection for image-guided stereotactic body radiation therapy (SBRT). From six different vendors, we selected 11 fiducials commonly used in image-guided radiation therapy (IGRT); the fiducials varied in material composition (gold, platinum, carbon), shape (cylindrical, notched/linear, coiled, ball-like, step), and size measured in terms of diameter (0.28-1.0 mm) and length (3.0-20.0 mm). Each fiducial was centered in 4-mm bolus within a 13-cm-thick water-equivalent phantom. Fiducials were imaged with use of a simulation computed tomography (CT) scanner, a CT-on-rails system, and an onboard cone-beam CT system. Acquisition parameters were set according to clinical protocols. Visibility was assessed in terms of contrast and the Michelson visibility metric. Artifacts were quantified in terms of relative standard deviation and relative streak artifacts level (rSAL). Twelve radiation oncologists ranked each fiducial in terms of clinical usefulness. Contrast and artifacts increased with fiducial size. For CT imaging, maximum contrast (2722 HU) and artifacts (rSAL=2.69) occurred for the largest-diameter (0.75 mm) platinum fiducial. Minimum contrast (551 HU) and reduced artifacts (rSAL=0.65) were observed for the smallest-diameter (0.28 mm) gold fiducial. Carbon produced the least severe artifacts (rSAL = 0.29). The survey indicated that physicians preferred gold fiducials with a 0.35- to 0.43-mm diameter, 5- to 10-mm length, and a coiled or cylindrical shape that balanced contrast and artifacts. We evaluated 11 different fiducials in terms of visibility and artifacts. The results of this study may assist radiation oncologists who seek to maximize contrast, minimize artifacts, and/or balance contrast versus artifacts by fiducial selection.

This paper outlines a system for using basic principles from optics to visually represent psychological states and processes, such as ideation, enlightenment, mindfulness, and fragmentation versus integrity, as well as situations that occur between people involving phenomena such as honest versus deceptive communication, and understanding versus misunderstanding. The paper summarizes two ongoing projects based on this system: The ‘Light and Enlightenment” art installation project, and the Soultracker virtual reality project. These projects enable people to depict their inner lives and external worlds including situations and relationships with others, both as they are and as they could be, and explore alternative paths for navigating challenges and living to their fullest potential. The projects aim to be of clinical value as therapeutic tools, as well as of pedagogical value by providing a concrete language for depicting aspects of human nature that can otherwise seem elusive and intangible.

description: This paper presents a comprehensive analysis and performance enhancement of short block length channel detection incorporating training information. The current communication systems' short block length channel detection typically consists of least squares channel estimation followed by quasi-coherent detection. By investigating the receiver structure, specifically the estimator-correlator, we show that the non-coherent term, often disregarded in conventional detection metrics, results in significant losses in performance and sensitivity in typical operating regimes of 5G and 6G systems. A comparison with the fully non-coherent receiver in multi-antenna configurations reveals substantial losses in low spectral efficiency operating areas. Additionally, we demonstrate that by employing an adaptive DMRS-data power adjustment, it is possible to reduce the performance loss gap, which is amenable to a more sensitive quasi-coherent receiver. However, both of the aforementioned ML detection strategies can result in substantial computational complexity when processing long bit-length codes. We propose an approach to tackle this challenge by introducing the principle of block or segment coding using First-Order RM Codes, which is amenable to low-cost decoding through block-based fast Hadamard transforms. The Block-based FHT has demonstrated to be cost-efficient with regards to decoding time, as it evolves from quadric to quasi-linear complexity with a manageable decline in performance. Additionally, by incorporating an adaptive DMRS-data power adjustment technique, we are able to bridge/reduce the performance gap with respect to the conventional maximum likelihood receiver and attain high sensitivity, leading to a good trade-off between performance and complexity to efficiently handle small payloads.

description: Since the 1990's, Uganda system has undergone various reforms. However, both tax policies and reforms have been formulated without clearly indication the channels through which gender impacts on these policies/reforms. Using the national household survey of 2005/06, this paper provided insight into how tax policies and reforms on indirect taxes impact differently on women and men. The incidence rate of tax gender-based household typologies controlled by expenditure quintile brings out interesting findings. The incidence rate of indirect tax is significantly greater on households headed by male compared to their female counterparts regardless of income level. This also holds after controlling for the presence of children. More importantly, the impact on different households typologies is largely influenced by differences in consumption patterns. future tax reforms should take these gender differences in account as a means of improving the social welfare of every Ugandan.

description: The pp -> pp pi0 differential cross section has been measured with the ANKE spectrometer at COSY-Juelich for pion cms angles between 0 and 15.4 degrees at a proton beam energy of 0.8 GeV. The selection of diproton pairs with an excitation energy E_{pp} < 3 MeV ensures that the final pp system is dominantly in the spin-singlet 1S0 state. The kinematics are therefore very similar to those of pp -> d pi+ but with different spin and isospin transitions. The results will thus provide a crucial extra test of pion production models in nucleon-nucleon collisions. The cross sections, which are over two orders of magnitude smaller than those of pp -> d pi+, show a forward dip, even stronger than that seen at lower energies. This behaviour is well reproduced in a theoretical model that includes P-wave Delta-N states.

Detailed theoretical models for extra-solar planet-host stars: The "red stragglers" HD37124 and HD46375

description: In this paper we analyse and discuss the HR Diagram position of two extra-solar planet-host stars - HD37124 and HD46375 - by means of theoretical stellar evolution models. This work was triggered by the results obtained by Laws et al. (2003) who found that these stars were in contradiction to the expectation based on their high metallicity. Fixing the age of both stars with the value based on their chromospheric activity levels and computing our own evolutionary models using the CESAM code, we are able to reproduce the observed luminosity, effective temperature and metallicity of both stars for a set of stellar parameters that are astrophysically reliable even if it is non-trivial to interpret the absolute values for these parameters. Our results are discussed in the context of the stellar properties of low mass stars.

description: The analysis of the status of the constitutive metaphor in science is considered along with the examination of some principal models of metaphors among biology, medicine and neurosciences. This allows to highlight the two ages of the scientific metaphor, the crossover between metaphors and models, and some open questions about the hidden ideologies concealed in the scientific theoretical terms that come from the use of metaphors.

description: During the Eighteenth Century – from Bonnet to Robinet, from Maupertuis to Diderot, and up to Buffon – several new topics of discussion were developed concerning materialism, the critique to finalism, the idea of nature as continuous metamorphosis (as apposed to the static, fixist and discontinuist theories of nature), the advocacy of providentialism, or, to the contrary, of the role of chaos. As a result, scales, prototypes and types have been employed as interpretative hypotheses influencing the main choices and lines of research. In this regard, however, Étienne Geoffroy Saint-Hilaire's work deeply modified the morphological metaphors. The teratologist's eye combined to the mineralogist's perspective established the priority of the material visibility of the living, based on the analysis of its structure rather than of its physiology. The single framework of organistion (unity of composition), on which base every being is formed is thus taken as the condition as well as the limit within which every possible variation in shape is fully justified.

description: We consider the known effective field theory of the Calogero-Sutherland model in the thermodynamic limit of large number of particles, obtained from the standard procedure in conformal field theory: the Hilbert space is constructed a priori in terms of irreducible representations of the symmetry algebra, and not by diagonalization of the hamiltonian, which is given in terms of fields that carry representations of the W-infinity algebra (representing the incompressibility of the Fermi sea). Nevertheless, the role of the effective hamiltonian of the theory is to establish a specific dynamics, which deserves further consideration. We show that the time evolution of the (chiral or antichiral) density field is given by the quantum Benjamin-Ono equation, in agreement with previous results obtained from the alternative description of the continuous limit of the model, based on quantum hydrodynamics. In this study, all calculations are performed at the quantum operator level, without making any assumption on the semiclassical limit of the fields and their equations of motion. This result may be considered as a reliable indication of the equivalence between the quantum field theoretic and quantum hydrodynamical formulations of the effective theories of the model. A one-dimensional quantum compressible fluid that includes both chiralities is the physical picture that emerges for the continuous limit of the Calogero-Sutherland model.

description: We consider equilibrium states (that is, shift-invariant Gibbs measures) on the configuration space $S^{\mathbb{Z}^d}$ where $d\geq 1$ and $S$ is a finite set. We prove that if an equilibrium state for a shift-invariant uniformly summable potential satisfies a Gaussian concentration bound, then it is unique. Equivalently, if there exist several equilibrium states for a potential, none of them can satisfy such a bound.

description: Like most developing countries, Uganda faces serious fiscal challenges in her effort to mobilize and effectively use resources for poverty reduction. however, the tax base remains small as reflected in the low tax-to-GDP. the government is under internal and external pressure to increase its domestic revenue collection and i turn, reduce its dependency on donors. In response to the pressure the government endeavored to maintain fiscal discipline, partly by raising taxes. the consequences of this move on the poor remains unclear. the main purpose of this paper is to throw light on the effects of alternative reforms to existing tax system on those households living in poverty. The analysis was carried out using the nationally representative Uganda national household survey of 1999/00 (UNHS I) using micro-simulation techniques. the key findings emerging from the analysis are: Increasing value added tax (VAT) other taxes unchanged will increase the tax burden of the poor but the non-poor households will continue paying more taxes relative to their expenditures that the poor households; Zero rating of the key taxable consumer items consumed by the poor would have little fiscal consequences. the amount of revenue forgone is less than the graduated tax (head tax) forgone; and the largest portion of the tax burden born by the poor households originates from VAT followed by excise duties and graduated tax.

description: We show that partons traversing a quark-gluon plasma can lose substantial amounts of energy also by scatterings, and not only through medium-induced radiation as mainly considered previously. Results from Monte Carlo simulations of soft interactions of partons, emerging from a hard scattering, through multiple elastic scatterings on gluons in an expanding relativistic plasma show a sizeable jet quenching which can account for a substantial part of the effect observed in RHIC data.
