Publisher: name: Unknown
Year: 2004
Subjects: Resource /Energy Economics and Policy

description: This paper outlines the economic surplus approach to economic impact assessment and how it may be applied to natural resource management (NRM) projects. Three challenges confront NRM impact assessment: measurement, attribution, and valuation of non-market impacts. While various methods for non-market valuation have been developed, none has yet been integrated into a market-based economic surplus analysis due to problems of measurement and theoretical consistency. Future research should address those integration problems as well as the effects on valuation of inter-country income differentials.

description: The paper develops the implications of competitive market equilibrium for production and household behavior when some prices are endogenously determined. The properties of market equilibrium functions are explored, including the effects of pricing policy. A Slutsky-type equation relating compensated and uncompensated market equilibrium functions is derived. Implications for multi-market welfare analysis are presented, focusing on the effects of pricing policy and technical change.

description: This paper experimentally measures the 'social capital' of altruism, trust and reciprocity and empirically explores the impact of these norms on economic well-being. Using an experimental design that distinguishes trust and reciprocity from altruism, data were collected from individuals in a random sample of South African communities. Analyzed at the community level, these data suggest that while related, trust and reciprocity are clearly different from altruism. Moreover, the relatively strong correlation between trust and reciprocity indicates that communities are in a sort of normative equilibrium, with trust strongest where reciprocity norms are most active. Finally, analysis of household living standard data drawn from these same communities shows that these norms have real economic effects on households' well-being. The effects of both altruism and trust are significantly positive in urban communities, whereas the effects of these same norms are weaker or negative in more traditional rural areas.

description: The relationship amongst state-redundancy and time consistency of differential games is investigated. A class of state-redundant games is detected, where the state dynamics and the payoff functions of all players are additively separable w.r.t. control variables. We prove that, in this class of games, open-loop Nash and degenerate feedback Stackelberg equilibria coincide, both being subgame perfect. This allows us to bypass the issue of the time inconsistency that typically affects the open-loop Stackelberg solution.

description: We use a rich personnel data set from a Russian firm for the years 1997 to 2002 to analyze how the financial crisis in 1998 and the resulting change in external labor market conditions affect the wages and the welfare of workers inside a firm. We provide evidence that large shocks to external conditions affect the firm’s personnel policies, and show that the burden of the shock is not evenly spread across the workforce. The firm takes advantage of a high-inflationary environment and of a fall in workers’ outside options after the financial crisis and cuts real wages. Earnings are curbed most for those who earned the highest rents, resulting in a strong compression of real wages. The fact that real wages and real compensation levels never recovered to pre-crisis levels even though the firm’s financial situation was better in 2002 than before the crisis and the differential treatment of employee groups within the firm can be taken as evidence that market forces strongly influence the wage policies of our firm.

description: The observed velocities of pulsars suggest the possibility that sterile neutrinos with mass of several keV are emitted from a cooling neutron star. The same sterile neutrinos could constitute all or part of cosmological dark matter. The neutrino-driven kicks can exhibit delays depending on the mass and the mixing angle, which can be compared with the pulsar data. We discuss the allowed ranges of sterile neutrino parameters, consistent with the latest cosmological and X-ray bounds, which can explain the pulsar kicks for different delay times.

description: La tesi di Dottorato, saldamente ancorata alle Medical Humanities, si è concentrata sul modo in cui la storia della letteratura italiana si intreccia con le altre discipline, per arrivare a configurare quell’ampio panorama di storia delle idee che aiuta a valutare l’evoluzione stessa delle credenze e dei pensieri dell’uomo nel corso del tempo. Essa ha contribuito a portare alla luce l’apporto dato dalla Società Medica Chirurgica di Bologna in Epoca Pontificia alla circolarità del pensiero medico, ricordando con forza che le varie correnti storico-mediche non sono appunto il semplice susseguirsi di teorie più o meno esatte. La tesi rende pienamente visibili non solo la struttura e le dinamiche della comunicazione scientifica, ma documenta attraverso la letteratura (anche quella scientifica) la presenza della medicina e delle sue pratiche all’interno della società, soffermandosi sui meccanismi, sui percorsi che legano i fenomeni tra loro; viene declinato anche il complesso e travagliato processo teso a ridefinire la figura del medico durante l’epoca del dominio pontificio nel suo declino, circondata da diffidenze e ostilità. Il fulcro della tesi è dato dalla dimostrazione inconfutabile che esiste ancora un ruolo per la cultura umanistica nella formazione del medico.
description: The PhD thesis, firmly anchored to the Medical Humanities, focused on how the history of Italian literature is interwined with other disciplines, in order to shape the broad views of the history of ideas which helps to evaluate the evolution of men’s beliefs and thoughts over the time. It has helped to bring to light the contribution made by the Medical and Surgical Society of Bologna in the Papacy Period to the circularity of medical thought, strongly recalling that the various historical and medical currents are not the simple succession of more or less accurate theories. The PhD thesis makes fully visible not only the structure and the dynamics of scientific communication, but it documents through literature (even the scientific literature) the presence of medicine and of its practices in the society, focusing on the mechanisms and routes that link the phenomena among them; it has also shown the complex and troubled process that aimed to redefine the figure of the doctor during the last Papacy Period, which was surrounded by suspicion and hostility. The focus of the PhD thesis is given by the irrefutable proof that there is still a role for the humanities in medical education.

description: We propose a new deformed Rieffel product for functions in de Sitter spacetime, and study the resulting deformation of quantum field theory in de Sitter using warped convolutions. This deformation is obtained by embedding de Sitter in a higher-dimensional Minkowski spacetime, deforming there using the action of translations and subsequently projecting back to de Sitter. We determine the two-point function of a deformed free scalar quantum field, which differs from the undeformed one, in contrast to the results in deformed Minkowski spacetime where they coincide. Nevertheless, we show that in the limit where de Sitter spacetime becomes flat, we recover the well-known non-commutative Minkowski spacetime.

description: The galaxy pair AM 1353-272 nicknamed "The Dentist's Chair" shows two ~30 kpc long tidal tails. Previous observations using multi-slit masks showed that they host up to seven tidal dwarf galaxies. The kinematics of these tidal dwarfs appeared to be decoupled from the surrounding tidal material. New observations of the tip of the southern tidal tail with the VIMOS integral field unit confirm the results for two of these genuine tidal dwarfs but raise doubts whether the velocity gradient attributed to the outermost tidal dwarf candidate is real. We also discuss possible effects to explain the observational difference of the strongest velocity gradient seen in the slit data which is undetected in the new integral field data, but arrive at no firm conclusion. Additionally, low-resolution data covering most of the two interacting partners show that the strongest line emitting regions of this system are the central parts.

description: Soil is the product of the action of climate and living organisms upon parent materials, as conditioned by local relief. The length of time over which these forces are operative is of great importance in determining the properties of the final soil product. Altogether, there are five principal factors in soil formation: 1.) climate, 2.) biological activity, 3.) nature of the parent material, 4.) topography, and 5.) time.  The major differences in the soils of Kentucky result chiefly from differences in 1.) the rocks from which the parent materials were derived and 2.) the topographic position of the materials.

description: Autonomous exploration requires robots to generate informative trajectories iteratively. Although sampling-based methods are highly efficient in unmanned aerial vehicle exploration, many of these methods do not effectively utilize the sampled information from the previous planning iterations, leading to redundant computation and longer exploration time. Also, few have explicitly shown their exploration ability in dynamic environments even though they can run real-time. To overcome these limitations, we propose a novel dynamic exploration planner (DEP) for exploring unknown environments using incremental sampling and Probabilistic Roadmap (PRM). In our sampling strategy, nodes are added incrementally and distributed evenly in the explored region, yielding the best viewpoints. To further shortening exploration time and ensuring safety, our planner optimizes paths locally and refine them based on the Euclidean Signed Distance Function (ESDF) map. Meanwhile, as the multi-query planner, PRM allows the proposed planner to quickly search alternative paths to avoid dynamic obstacles for safe exploration. Simulation experiments show that our method safely explores dynamic environments and outperforms the benchmark planners in terms of exploration time, path length, and computational time.

description: The objective of this study is to provide an empirical evaluation of the expected relationship between cash and futures prices for fluid milk. This is done using historic cash prices from 1988 to 1995, and making inferences about how futures prices would have behaved if they had traded during this sample period. Futures prices are simulated over the sample period based on two assumptions about futures market behavior for fluid milk. The first is that the futures market will essentially price the Basic Formula Price (BFP). The BFP is an estimate of the previous month's pay price for Grade B manufacturing milk in Minnesota and Wisconsin adjusted for contemporaneous changes in the prices of manufactured milk products. It establishes the federal milk marketing order minimum Grade A pay price for Class III milk used to make cheese, and is the mover of both the minimum Class II price for milk used in soft manufacturing products and the minimum Class I price for beverage milk (Jesse).

description: In the summer of 1952 the Flexible Pavement Design Committee of the Highway Research Board began the sponsoring of a comparative design project. Several state highway departments and other organizations were invited to submit flexible pavement designs, based upon their own current practices, for the subgrade, materials, and traffic conditions of the Western Association of State Highway Officials (WASHO) test road. This road was being constructed in Malad, Idaho, through the participation of 13 western states and the Bureau of Public Roads. The Kentucky Department of Highways was one of the organizations invited to participate in the comparative design project.
Diagnostics of irradiated gas in galaxy nuclei. I: A Far-ultraviolet and X-ray dominated region code

description: We present a far-ultraviolet (PDR) and an X-ray dominated region (XDR) code. We include and discuss thermal and chemical processes that pertain to irradiated gas. An elaborate chemical network is used and a careful treatment of PAHs and H2 formation, destruction and excitation is included. For both codes we calculate four depth-dependent models for different densities and radiation fields, relevant to conditions in starburst galaxies and active galactic nuclei. A detailed comparison between PDR and XDR physics is made for total gas column densities between ~10^20 and ~10^25 cm^-2. We show cumulative line intensities for a number of fine-structure lines (e.g., [CII], [OI], [CI], [SiII], [FeII]), as well as cumulative column densities and column density ratios for a number of species (e.g., CO/H2, CO/C, HCO+/HCN, HNC/HCN). The comparison between the results for the PDRs and XDRs shows that column density ratios are almost constant up to N_H=10^22 cm^-2 for XDRs, unlike those in PDRs. For example, CO/C in PDRs changes over four orders of magnitude from the edge to N_H=10^22 cm^-2. The CO/C and CO/H2 ratios are lower in XDRs at low column densities and rise at N_H > 10^23 cm^-2. At most column densities N_H > 10^21.5 cm^-2, HNC/HCN ratios are lower in XDRs too, but they show a more moderate increase at higher N_H.

description: This study proposes a detailed nonlinear mathematical model of an antagonistic pneumatic artificial muscle (PAM) actuator system for estimating the joint angle and torque using an unscented Kalman filter (UKF). The proposed model is described in a hybrid state-space representation. It includes the contraction force of the PAM, joint dynamics, fluid dynamics of compressed air, mass flows of a valve, and friction models. A part of the friction models is modified to obtain a novel form of Coulomb friction depending on the inner pressure of the PAM. For model validation, offline and online UKF estimations and sensor-less tracking control of the joint angle and torque are conducted to evaluate the estimation accuracy and tracking control performance. The estimation accuracy is less than 7.91 %, and the steady-state tracking control performance is more than 94.75 %. These results confirm that the proposed model is detailed and could be used as the state estimator of an antagonistic PAM system.

description: Charged particles can be accelerated to high energies by collisionless shock waves in astrophysical environments, such as supernova remnants. By interacting with the magnetized ambient medium, these shocks can transfer energy to particles. Despite increasing efforts in the characterization of these shocks from satellite measurements at the Earth's bow shock and powerful numerical simulations, the underlying acceleration mechanism or a combination thereof is still widely debated. Here, we show that astrophysically relevant super-critical quasi-perpendicular magnetized collisionless shocks can be produced and characterized in the laboratory. We observe characteristics of super-criticality in the shock profile as well as the energization of protons picked up from the ambient gas to hundreds of keV. Kinetic simulations modelling the laboratory experiment identified shock surfing as the proton acceleration mechanism. Our observations not only provide the direct evidence of early stage ion energization by collisionless shocks, but they also highlight the role this particular mechanism plays in energizing ambient ions to feed further stages of acceleration. Furthermore, our results open the door to future laboratory experiments investigating the possible transition to other mechanisms, when increasing the magnetic field strength, or the effect induced shock front ripples could have on acceleration processes.

description: A detailed assessment of employment trends in the public sector from 1979 to 2001 is provided. Particular attention is paid to the relative level of public sector employment is Wisconsin . The analysis also examines the relationship between the size of state and local government and overall employment growth from 1979-2001. Results suggest that growth in total employment and employment in the public sector are highly correlated; higher shares of total employment in the public sector in the beginning of the period are not correlated with subsequent growth rates; but a state that sees the public sector grow faster then overall employment growth tends to be associated with slower overall growth. In addition, when measuring the size of the public sector in terms of employment, Wisconsin does not appear to be out of balance when compared to other states. Employment growth in state government over the period 1979-2001 is one of the lowest in the country and employment growth at the local government level is slightly above the national average. Detailed changes in employment by category are also examined for the US and Wisconsin from 1993 to 2002. These data suggest that there has been significant disinvestment in several areas that contribute to the overall quality of life in Wisconsin which may in turn hinder the future potential for economic growth and development.

description: For the last twenty-five years considerable research has been directed toward developing reliable equipment for evaluating pavement roughness. Since roughness inhibits passenger riding comfort and safety, as well as inducing vehicle deterioration, the determination of the features that cause roughness would indicate possible improvements in pavement design, materials, construction practices and equipment. For example, certain types of base design might be found to produce smoother surfaces than others; and a construction practice such as a blade-spread leveling course might result in more uniform pavements. Then too, evaluation of pavement roughness would permit relative comparison of pavements as one of several factors in determining the most needed of possible improvements, with the normally limited finances available. This could appear in a tabulation of sufficiency ratings such as those used by the Kentucky Department of Highway.

description: We report on IRAC-4.5mic, IRAC-8.0mic and MIPS-24mic deep observations of 16 Gamma-Ray Burst (GRBs) host galaxies performed with the Spitzer Space Telescope, and we investigate in the thermal infrared the presence of evolved stellar populations and dust-enshrouded star-forming activity associated with these objects. Our sample is derived from GRBs that were identified with sub-arcsec localization between 1997 and 2001, and only a very small fraction (~20%) of the targeted sources is detected down to f_4.5mic ~3.5microJy and f_24mic ~85microJy (3sigma). This likely argues against a population dominated by massive and strongly-starbursting (i.e., SFR > ~100 Msol/yr) galaxies as it has been recently suggested from submillimeter/radio and optical studies of similarly-selected GRB hosts. Furthermore we find evidence that some GRBs do not occur in the most infrared-luminous regions -- hence the most actively star-forming environments -- of their host galaxies. Should the GRB hosts be representative of all star-forming galaxies at high redshift, models of infrared galaxy evolution indicate that > ~50% of GRB hosts should have f_24mic > ~100microJy. Unless the identification of GRBs prior to 2001 was prone to strong selection effects biasing our sample against dusty galaxies, we infer in this context that the GRBs identified with the current techniques can not be directly used as unbiased probes of the global and integrated star formation history of the Universe.

Intrinsic oceanic decadal variability of upper-ocean heat content

description: Atmosphere and ocean are coupled via air-sea interactions. The atmospheric conditions fuel the ocean circulation and its variability, but the extent to which ocean processes can affect the atmosphere at decadal time scales remains unclear. In particular, such low-frequency variability is difficult to extract from the short observational record, meaning that climate models are the primary tools deployed to resolve this question. Here, we assess how the ocean's intrinsic variability leads to patterns of upper-ocean heat content that vary at decadal time scales. These patterns have the potential to feed back on the atmosphere and thereby affect climate modes of variability, such as El Niño or the Interdecadal Pacific Oscillation. We use the output from a global ocean-sea ice circulation model at three different horizontal resolutions, each driven by the same atmospheric reanalysis. To disentangle the variability of the ocean's direct response to atmospheric forcing from the variability due to intrinsic ocean dynamics, we compare model runs driven with inter-annually varying forcing (1958-2018) and model runs driven with repeat-year forcing. Models with coarse resolution that rely on eddy parameterizations, show (i) significantly reduced variance of the upper-ocean heat content at decadal time scales and (ii) differences in the spatial patterns of low-frequency variability compared with higher resolution models. Climate projections are typically done with general circulation models with coarse-resolution ocean components. Therefore, these biases affect our ability to predict decadal climate modes of variability and, in turn, hinder climate projections. Our results suggest that for improving climate projections, the community should move towards coupled climate models with higher oceanic resolution.
Solid state photochemistry and X-ray crystallography of carbonyl-containing compounds

description: This thesis reports the role of the crystalline environment in influencing the solid state photochemistry of carbonyl-containing compounds. Two types of photochemical reactions were studied: electrocyclization and hydrogen atom abstraction. The structure-reactivity relationships in systems undergoing these reactions were revealed with the use of single crystal X-ray crystallography using the X-ray Structure-Solid State Reactivity Correlation Method. chiral conformations. The prospect of using this conformational chirality for studies of absolute asymmetric synthesis was explored. The effects of halogen substitution on the crystal packing are also discussed. A series of halo-substituted enamides (I) was synthesized and the photochemical behaviour of each enamide was studied. These substrates undergo a concerted photochemical ring closure in solution. Although formally achiral, the enamides can adopt The crystal structures of a homologous series of spirobenzoyladamantanes (III - VI) were determined. These compounds undergo photochemical y-hydrogen atom abstraction in the solid state. The fates of their 1,4- biradicals can be rationalized using biradical geometries derived from the crystal data. The crystal structures of a series of cw-9-decalyl aryl ketones (XI) were determined. These compounds undergo hydrogen atom abstraction reactions in the solid state. The role of the crystalline environment in directing the formation of regio- and diastereoselective photoproducts was determined. Asymmetric synthesis in the carboxylic acid derivatives of XI was studied using the Ionic Chiral Auxilary Concept, and the photochemical results obtained from this approach were rationalized from the crystal structures. The crystal structures of a series of a-mesitylacetophenones (XVI) were determined, and correlated with their photochemical reactivities. These compounds undergo 5- hydrogen atom abstraction in the solid state, and the photochemistry is discussed in terms of the molecular abstraction geometries derived from the crystal data. Asymmetric induction in the optically active salts of the carboxylic acid derivative of this system was also studied, and the photochemical results were rationalized from the crystal structures.

description: Significant baryon over meson enhancement was measured at RHIC in the intermediate transverse momentum range of $p_T=2-4$ GeV/$c$ ("baryon-meson puzzle"). With STAR detector we were able to extend particle identification towards higher transverse momentum offering further insights into the particle production mechanisms at intermediate to high $p_T$. In this paper we present results on charged pion, proton and anti-proton spectra and ratios at intermediate to high $p_T$ exploiting the relativistic rise of the specific ionization energy loss measured in the STAR Time Projection Chamber. These measurements provide valuable information about the production mechanisms of particles at intermediate $p_T$ in relativistic heavy ion collisions, e.g. coalescence/recombination versus jet fragmentation.

description: This paper presents an incentive scheme to control agricultural non-point-source pollution. The analysis is based on a nested agent framework with three parties; farmers, a country's government, and the governments of all countries that affect each other's environmental quality. Unlike previous analysis of incentive schemes to control agricultural pollution, we suggest non-individual contracts between farmers and a regulating authority as a solution to the domestic pollution problem. Our incentive scheme proposes collective penalties as a way to control pollution. To solve the international problem of pollution management of a common (water) resource, we propose an international agency with authority to write and enforce contracts in each of its member countries. We show that the information requirement on a country's government can be substantially reduced if contracts can be made non-individual.

description: We study the stability of quantum droplet and its associated phase transitions in ultracold Bose-Bose mixtures uniformly confined in quasi-two-dimension. We show that the confinement-induced boundary effect can be significant when increasing the atom number or reducing the confinement length, which destabilizes the quantum droplet towards the formation of a soliton bound state. In particular, as increasing the atom number we find the reentrance of soliton ground state, while the droplet is stabilized only within a finite number window that sensitively depends on the confinement length. Near the droplet-soliton transitions, they can coexist with each other as two local minima in the energy landscape. Take the two-species $^{39}$K bosons for instance, we have mapped out the phase diagram for droplet-soliton transition and coexistence in terms of atom number and confinement length. The revealed intriguing competition between quantum droplet and soliton under confinement can be readily probed in current cold atoms experiments.

description: The decay of a local spin excitation in an inhomogeneous spin chain is evaluated exactly: I) It starts quadratically up to a spreading time t_{S}. II) It follows an exponential behavior governed by a self-consistent Fermi Golden Rule. III) At longer times, the exponential is overrun by an inverse power law describing return processes governed by quantum diffusion. At this last transition time t_{R} a survival collapse becomes possible, bringing the polarization down by several orders of magnitude. We identify this strongly destructive interference as an antiresonance in the time domain. These general phenomena are suitable for observation through an NMR experiment.

description: The dramatically growing availability of observational data is being witnessed in various domains of science and technology, which facilitates the study of causal inference. However, estimating treatment effects from observational data is faced with two major challenges, missing counterfactual outcomes and treatment selection bias. Matching methods are among the most widely used and fundamental approaches to estimating treatment effects, but existing matching methods have poor performance when facing data with high dimensional and complicated variables. We propose a feature selection representation matching (FSRM) method based on deep representation learning and matching, which maps the original covariate space into a selective, nonlinear, and balanced representation space, and then conducts matching in the learned representation space. FSRM adopts deep feature selection to minimize the influence of irrelevant variables for estimating treatment effects and incorporates a regularizer based on the Wasserstein distance to learn balanced representations. We evaluate the performance of our FSRM method on three datasets, and the results demonstrate superiority over the state-of-the-art methods.

description: Using a longitudinal survey of South African households over the 1993-2004 period, this paper evaluates changes in income distribution since the end of apartheid. Inequality amongst these households has markedly increased this period as initially better off households consistently improved their economic well-being. Sharp increases in measured poverty over the first half of this period were partially reversed by later improvements for some poor households. Comparisons between actual and "market-generated" income distributions suggest that these improvements were driven in part by government transfer programs. Nonetheless, the chronically poor remain a significant fraction of the total poor, and 60% of those households that were poor in 1993 are still poor in 2004. Analysis of the next generation (that is the now grown children of the original survey households) shows a similar pattern of bifurcation, with one group moving ahead rapidly, and another mired at low living levels.

description: Using data from a national living standards survey undertaken in late 1993, this paper disaggregates and explores the economics of livelihood generation and class in rural South Africa in an effort to contribute to the ongoing and vociferous debate in South Africa about poverty and its alleviation. Pursuant to the suggestion of participants in a recent participatory poverty assessment, this paper analyzes what might be termed the class structure of poverty. After exploring the range of claiming systems and livelihood tactics available in rural South Africa, the paper offers a first look at who the poor are by disaggregating the rural population into discrete livelihood strategy classes. Non-parametric regression methods are used to then estimate and graphically explore the nature of the livelihood mapping between endowments and real incomes. In addition to identifying those endowment combinations which map to consumption levels below the poverty line (the asset basis of poverty), the topography of the estimated livelihood mapping helps identify the constraints which limit household's ability to effectively utilize their assets and endowments. These results suggest that poverty is a matter of not only having few assets, but also of constraints which limit the effectiveness with which those assets are used, and poverty and livelihood policy needs to be designed accordingly.

description: Home-cage social behaviour analysis of mice is an invaluable tool to assess therapeutic efficacy of neurodegenerative diseases. Despite tremendous efforts made within the research community, single-camera video recordings are mainly used for such analysis. Because of the potential to create rich descriptions of mouse social behaviors, the use of multi-view video recordings for rodent observations is increasingly receiving much attention. However, identifying social behaviours from various views is still challenging due to the lack of correspondence across data sources. To address this problem, we here propose a novel multiview latent-attention and dynamic discriminative model that jointly learns view-specific and view-shared sub-structures, where the former captures unique dynamics of each view whilst the latter encodes the interaction between the views. Furthermore, a novel multi-view latent-attention variational autoencoder model is introduced in learning the acquired features, enabling us to learn discriminative features in each view. Experimental results on the standard CRMI13 and our multi-view Parkinson's Disease Mouse Behaviour (PDMB) datasets demonstrate that our model outperforms the other state of the arts technologies and effectively deals with the imbalanced data problem.

Study of silicon photomultipliers for use in neutron decay experiments

description: Photon readout of plastic scintillators is investigated with the aim of improving the precision of neutron \b{eta} decay experiments. Neutron decay is nowadays studied with high statistics, based on up to 109 registered decay events, and leads to strongly improved limits on new physics beyond the standard model, with \b{eta}s often registered in plastic scintillators. The main systematic errors in these experiments are due to imperfect characterization of the scintillators with respect to linearity, energy resolution, and electron backscattering. We study whether these errors can be diminished when the conventional photomultipliers used for scintillator readout are replaced by silicon photomultipliers (SiPMs). To this end, various theoretical and experimental tools are developed, and a procedure for handling the extreme dark rates of SiPMs is proposed. In \b{eta} spectroscopy, so the conclusion, plastic scintillator readout with SiPMs can significantly improve energy response, and help providing reliable corrections for electron backscattering.

description: The aim of this paper is to study the pro-algebraic fundamental group of a compact Kaehler manifold. Following work by Simpson, the structure of this group's pro-reductive quotient is already well understood. We show that Hodge-theoretic methods can also be used to establish that the pro-unipotent radical is quadratically presented. This generalises both Deligne et al.'s result on the de Rham fundamental group, and Goldman and Millson's result on deforming representations of Kaehler groups, and can be regarded as a consequence of formality of the schematic homotopy type. New examples are given of groups which cannot arise as Kaehler groups.
