description: This paper explores the impact of technological change on industry concentration and the underlying firm dynamics. In the agent-based model EURACE@Unibi I implement a paradigm shift in the technological frontier – a shift from a slow to a fast growing regime. The analysis shows that the acceleration in technological change causes a strong increase in market concentration. The reallocation of market shares towards a few large firms is driven by diverging productivities and skills across firms. An ex-post analysis reveals that after the paradigm shift small, but undervalued firms become the large dominating ones in the long-run. Their success gets initiated by a fortunate outcome on the labor market, which increases their skill level. With the faster technological change, their high skilled workforce incentivizes them to invest at the frontier and to build up the most productive capital stock. A virtuous cycle between their decisions on the labor and capital market further increases the productivity gap towards competitors enabling their rise.

description: The double-beta decay Q values of 130Te, 128Te, and 120Te have been determined from parent-daughter mass differences measured with the Canadian Penning Trap mass spectrometer. The 132Xe-129Xe mass difference, which is precisely known, was also determined to confirm the accuracy of these results. The 130Te Q value was found to be 2527.01(32) keV which is 3.3 keV lower than the 2003 Atomic Mass Evaluation recommended value, but in agreement with the most precise previous measurement. The uncertainty has been reduced by a factor of 6 and is now significantly smaller than the resolution achieved or foreseen in experimental searches for neutrinoless double-beta decay. The 128Te and 120Te Q values were found to be 865.87(131) keV and 1714.81(125) keV, respectively. For 120Te, this reduction in uncertainty of nearly a factor of 8 opens up the possibility of using this isotope for sensitive searches for neutrinoless double-electron capture and electron capture with positron emission.

description: We present a spectroscopic study of excitation dynamics in self assembled CdTe/ZnTe quantum dots. Insight into details of kinetics is obtained from the time resolved micro-photoluminescence, single photon correlation and subpicosecond excitation correlation measurements done on single quantum dots. It is shown that the pulsed excitation in energy above the energy gap of the barrier material results in separate capture of electrons and holes. The capture of carriers of different charge take place at different delay from excitation.

Precipitation of the Fraser River basin : a descriptive study.
Creators: name: Wallis, John Hubert
Publisher: name: University of British Columbia
Year: 2011

description: This study of precipitation is based on data in the 1955 Climate of British Columbia concerning the network of 106 stations which have been operated in the Fraser River Basin, Emphasis is on the description of precipitation characteristics, with cartographic representation of the data forming the basis of the explanations and discussion in the The first portion of the study concerns the concentration of annual and seasonal precipitation throughout the Basin, followed by a similar examination of mean annual and seasonal snowfall with observations concerning the proportion of annual snowfall in each season and the proportion of seasonal precipitation which occurs as snow. A parallel discussion of proportions for total precipitation, with emphasis on seasons and months of maximum and minimum, is concluded by an analysis of precipitation regimes in various parts of the Basin. The effect of the gaps in the Coast Mountains resulting in continental or coastal characteristics of precipitation, dependent on station location, is noted repeatedly throughout the thesis. Considerations of variability as well as the value and methods of checking homogeneity of station records are included with observations concerning years in which heavy or light precipitation was general in large parts of the Basin. An examination of all topics as they affect the thirteen sub-basins of the Fraser concludes the study.

description: In 1981 Hong and Kung proved a lower bound on the amount of communication needed to perform dense, matrix-multiplication using the conventional $O(n^3)$ algorithm, where the input matrices were too large to fit in the small, fast memory. In 2004 Irony, Toledo and Tiskin gave a new proof of this result and extended it to the parallel case. In both cases the lower bound may be expressed as $Ω$(#arithmetic operations / $\sqrt{M}$), where M is the size of the fast memory (or local memory in the parallel case). Here we generalize these results to a much wider variety of algorithms, including LU factorization, Cholesky factorization, $LDL^T$ factorization, QR factorization, algorithms for eigenvalues and singular values, i.e., essentially all direct methods of linear algebra. The proof works for dense or sparse matrices, and for sequential or parallel algorithms. In addition to lower bounds on the amount of data moved (bandwidth) we get lower bounds on the number of messages required to move it (latency). We illustrate how to extend our lower bound technique to compositions of linear algebra operations (like computing powers of a matrix), to decide whether it is enough to call a sequence of simpler optimal algorithms (like matrix multiplication) to minimize communication, or if we can do better. We give examples of both. We also show how to extend our lower bounds to certain graph theoretic problems. We point out recently designed algorithms for dense LU, Cholesky, QR, eigenvalue and the SVD problems that attain these lower bounds; implementations of LU and QR show large speedups over conventional linear algebra algorithms in standard libraries like LAPACK and ScaLAPACK. Many open problems remain.

Diffraction by a small aperture in conical geometry: Application to metal coated tips used in near-field scanning optical microscopy

description: Light diffraction through a subwavelength aperture located at the apex of a metallic screen with conical geometry is investigated theoretically. A method based on a multipole field expansion is developed to solve Maxwell's equations analytically using boundary conditions adapted both for the conical geometry and for the finite conductivity of a real metal. The topological properties of the diffracted field are discussed in detail and compared to those of the field diffracted through a small aperture in a flat screen, i. e. the Bethe problem. The model is applied to coated, conically tapered optical fiber tips that are used in Near-Field Scanning Optical Microscopy. It is demonstrated that such tips behave over a large portion of space like a simple combination of two effective dipoles located in the apex plane (an electric dipole and a magnetic dipole parallel to the incident fields at the apex) whose exact expressions are determined. However, the large "backward" emission in the P plane - a salient experimental fact that remained unexplained so far - is recovered in our analysis which goes beyond the two-dipole approximation.

description: We investigate the existence and stability of gap vortices and multi-pole gap solitons in a Kagome lattice with a defocusing nonlinearity both in a discrete case and in a continuum one with periodic external modulation. In particular, predictions are made based on expansion around a simple and analytically tractable anti-continuum (zero coupling) limit. These predictions are then confirmed for a continuum model of an optically-induced Kagome lattice in a photorefractive crystal obtained by a continuous transformation of a honeycomb lattice.
Vector length agnostic SIMD parallelism on modern processor architectures with the focus on Arm's SVE
Creators: name: Brank, Bine
Publisher: name: Bergische Universität Wuppertal
Year: 2023

description: This thesis analyzes SVE, a novel SIMD extension for Arm architectures. SVE removes the concept of vector size from the ISA, which allows CPU implementations with different vector sizes to execute the same SIMD instructions. In our work, we ask what consequences this has on application developers and computer architects. We select a set of standard HPC benchmarks and applications for the analysis and rely on Gem5, a state-of-the-art simulator for computer architecture research.We first evaluate the SVE ISA by looking at the vectorization of specific loops and searching for new vectorization opportunities. Afterward, we analyze how the VLA concept translates to algorithms and kernels in HPC. Finally, we study how different SVE lengths impact the execution and behavior of components in the microarchitecture. Our results show that the VLA paradigm in many algorithms naturally extends the fixed-width SIMD implementation. A larger SVE size results in better performance, especially in compute-bound kernels. At the same time, we show that different SIMD widths in a CPU can significantly affect the out-of-order execution and influence bottlenecks in various microarchitectural components.

description: Observations of the HI 21cm transition line promises to be an important probe into the cosmic dark ages and epoch of reionization. One of the challenges for the detection of this signal is the accuracy of the foreground source removal. This paper investigates the extragalactic point source contamination and how accurately the bright sources ($\gtrsim 1$ ~Jy) should be removed in order to reach the desired RMS noise and be able to detect the 21cm transition line. Here, we consider position and flux errors in the global sky-model for these bright sources as well as the frequency independent residual calibration errors. The synthesized beam is the only frequency dependent term included here. This work determines the level of accuracy for the calibration and source removal schemes and puts forward constraints for the design of the cosmic reionization data reduction scheme for the upcoming low frequency arrays like MWA,PAPER, etc. We show that in order to detect the reionization signal the bright sources need to be removed from the data-sets with a positional accuracy of $\sim 0.1$ arc-second. Our results also demonstrate that the efficient foreground source removal strategies can only tolerate a frequency independent antenna based mean residual calibration error of $\lesssim 0.2 %$ in amplitude or $\lesssim 0.2$ degree in phase, if they are constant over each days of observations (6 hours). In future papers we will extend this analysis to the power spectral domain and also include the frequency dependent calibration errors and direction dependent errors (ionosphere, primary beam, etc).

description: A new family of dynamic states are found in a stack of inductively coupled intrinsic Josephson junctions in the absence of an external magnetic field. In this state, $(2m_l+1)π$ phase kinks with integers $m_l$'s stack along the c axis and lock neighboring junction together. Large dc power is pumped into plasma oscillation via kinks at the cavity resonance. The plasma oscillation is uniform along the c axis with the frequency satisfying the ac Josephson relation. Thus this state supports strong terahertz radiation and seems to be compatible with the recent experimental observations.

Passive and Active Waveguide Systems for Solar Concentrators
Creators: name: Meudt, Maik
Publisher: name: Bergische Universität Wuppertal

description: Solar energy is an important renewable energy and plays a major role in the energy transition. Herein, photovoltaics is a growing field that promises to establish solar energy harvesting both in large-scale power plants as well as in urban spaces and shows a trend of increasing production capacity and speed, and decreasing costs. However, mastering the energy transition within a few decades demands a further boost in production speed. A way to achieve such a boost is concentrated photovoltaics (CPV): by placing a solar cell in the focus of a low-cost solar concentrator, the cells required area size can be reduced by the concentration factor of the solar concentrator. However, CPV needs sun trackers to mechanically adjust the solar concentrator to the sun. Herein, sun trackers have crucial drawbacks such as high costs, large weight, bulkiness, and high precision demands.In this thesis, waveguide systems are investigated with regard to their capability of improving CPV and establishing mechanics-free, thin sun trackers. In a first passive system, plasmonic nanoparticles interacting with surface plasmons are found to increase light-matter interaction and show broadband light absorption, which could be used for solar thermal applications. In another passive waveguide system, the TE node modes of symmetric periodic dielectric waveguides show an increase in light concentration by a factor of 1000. In a third passive system, both dielectric and structured plasmonic waveguides form a hybrid waveguide. For certain geometric symmetries, the diffraction of light out of the hybrid waveguide can be suppressed for one wavelength. In an active waveguide system, it is shown that combining active electro-optic waveguides with a structured passive waveguide enables the local control of the coupling into or out of the waveguide over a broad spectral range. This local control, in comb++

description: During the last few years the Tevatron has improved the bounds on rare $B$-meson decays into two leptons. Sensitivity to this decay is also one of the benchmark goals for LHCb performance. We compute the complete 1-loop MSSM contribution to $B^0_{s,d}\to μ^+\^-mu$ and study the predictions for arbitrary flavour mixing parameters. We discuss the possibility of both enhancing and suppressing the branching ratios relative to their SM expectations. We find that there are ``cancellation regions'' in parameter space where the branching ratio is suppressed well below the SM expectation, making it effectively invisible to the LHC.

description: We report the first two-dimensional stellar population synthesis in the near-infrared of the nuclear region of an active galaxy, namely Mrk1066. We have used integral field spectroscopy with adaptive optics at the Gemini North Telescope to map the to map the age distribution of the stellar population in the inner 300 pc at a spatial resolution of 35 pc. An old stellar population component (age >5Gyr) is dominant within the inner ~160pc, which we attribute to the galaxy bulge. Beyond this region, up to the borders of the observation field (~300 pc), intermediate age components (0.3-0.7Gyr) dominate. We find a spatial correlation between this intermediate age component and a partial ring of low stellar velocity dispersions (sigma). Low-sigma nuclear rings have been observed in other active galaxies and our result for Mrk1066 suggests that they are formed by intermediate age stars. This age is consistent with an origin for the low-sigma rings in a past event which triggered an inflow of gas and formed stars which still keep the colder kinematics (as compared to that of the bulge) of the gas from which they have formed. At the nucleus proper we detect, in addition, two unresolved components: a compact infrared source, consistent with an origin in hot dust with mass ~1.9x10^{-2} M_Sun, and a blue featureless power-law continuum, which contributes with only ~15% of the flux at 2.12 microns.

description: A new map of the sky representing the degree of randomness in the cosmic microwave background (CMB) temperature has been obtained. The map based on estimation of the Kolmogorov stochasticity parameter clearly distinguishes the contribution of the Galactic disk from the CMB and reveals regions of various degrees of randomness that can reflect the properties of inhomogeneities in the Universe. For example, among the high randomness regions is the southern non-Gaussian anomaly, the Cold Spot, with a stratification expected for the voids. Existence of its counterpart, a Northern Cold Spot with almost identical randomness properties among other low-temperature regions is revealed. By its informative power, Kolmogorov's map can be complementary to the CMB temperature and polarization sky maps.

description: Dyslexia represents one of the most frequent specific learning disorders, affecting reading fluency and word recognition in children worldwide 1. Recent technological advances—particularly in eye‐tracking hardware and machine learning algorithms—offer novel approaches for earlier and more accurate dyslexia diagnostics 2. The ETDD70 (Eye‐Tracking Dyslexia Dataset) comprises data from 70 Czech children aged 9–10, including 35 dyslexic and 35 non‐dyslexic participants. Each child performed three reading tasks in Czech: Syllables, MeaningfulText, and PseudoText. This study presents a comprehensive, end‐to‐end pipeline employing aggregated eye‐tracking features and advanced classification models (CatBoost and XGBoost) to distinguish dyslexic from non‐dyslexic readers. We outline data collection methods, feature engineering strategies, and multi‐fold cross‐validation procedures. While full‐feature models yielded around 80% accuracy, selective feature approaches (top five features) improved results to about 82.86% accuracy, with an F1‐score of approximately 0.813 and an AUC of around 0.927 using CatBoost. We also discuss potential optimizations, including multi‐modal testing, deeper hyperparameter tuning, and novel advanced re‐education tools. This paper aims to serve as a reference point for researchers seeking to leverage eye‐tracking data in the domain of dyslexia diagnosis, bridging computational techniques and educational neuroscience 3.

description: Macroscopic plasma polarization, which is created by gravitation and other mass-acting (inertial) forces in massive astrophysical objects (MAO) is under discussion. Non-ideality effect due to strong Coulomb interaction of charged particles is introduced into consideration as a new source of such polarization. Simplified situation of totally equilibrium isothermal star without relativistic effects and influence of magnetic field is considered. The study is based on conditions of constancy for generalized (electro)chemical potentials and/or conditions of equilibrium for the forces acting on each charged specie. New "non-ideality force" appears in this consideration. Hypothetical sequences of gravitational, inertial and non-ideality polarization on thermo- and hydrodynamics of MAO are under discussion.

A study of the mode of action of isoidide dinitrate.
Creators: name: Clark, Stewart Cecil
Publisher: name: University of British Columbia
Year: 2011

description: Isoidide dinitrate (IIDN), a new nitrate ester, an isomer of isosorbide dinitrate (ISDN) and isomannide dinitrate (IMDN), has been studied on the isolated rabbit intestine and on the anesthetized rat blood pressure. Potency was observed as was tachyphylaxis and the effect of certain blocking agents. On the isolated rabbit intestine similar results were obtained when nitroglycerin was substituted for IIDN. In both preparations IIDN was more potent than ISDN or IMDN and ISDN more potent than IMDN. The potency dependence on configuration suggests a possible action on specific receptor sites. A type of tachyphylaxis to IIDN which was prominent in the isolated rabbit intestine was almost absent in the anesthetized rat blood pressure. This is probably due to metabolism of the drug in the intact animal and further suggests an action on receptors. In these preparations the nitrate action was not blocked by: the beta adrenergic blocking agents DCI or nethalide, the alpha adrenergic blocking agent dibenzyline, or a combination of an alpha and a beta blocking agent. Drugs that are selectively blocked by these agents were used as controls to indicate the presence of the desired blocking action. Neither the primary bretylium-like action nor the secondary reserpine-like action of guanethidine blocked the effect of IIDN on the isolated rabbit intestine. Depletion of catechol amines by pretreating the animals with reserpine did not alter the response of either preparation to the nitrate esters. The antihistamine diphenhydramine did not block the vasodepressor action of IIDN on the anesthetized rat blood pressure. It was concluded that although IIDN probably does not exert its effect through combination with adrenergic or histaminergic receptors, it possibly acts on receptors which are specific for the nitrite or nitrate group.

description: It has been shown recently that phantom-like effect can be realized on the normal branch of the DGP setup without introduction of any phantom matter neither in the bulk nor on the brane and therefore without violation of the null energy condition. It has been shown also that inclusion of the Gauss-Bonnet term in the bulk action modifies this picture via curvature effects. Here, based on the Lue-Starkman conjecture on the dynamical screening of the brane cosmological constant in the DGP setup, we extend this proposal to a general DGP-inspired $f(R,ϕ)$ model that stringy effects in the ultra-violet sector of the theory are taken into account by inclusion of the Gauss-Bonnet term in the bulk action. We study cosmological dynamics of this setup, especially its phantom-like behavior and possible crossing of the phantom divide line especially with a non-minimally coupled quintessence field on the brane. In this setup, scalar field and curvature quintessence are treated in a unified framework.

description: The adsorption of fluorine, chlorine, bromine, and iodine diatomic molecules on graphene has been investigated using density functional theory with taking into account nonlocal correlation effects by means of vdW-DF approach. It is shown that the van der Waals interaction plays a crucial role in the formation of chemical bonding between graphene and halogen molecules, and is therefore important for a proper description of adsorption in this system. In-plane orientation of the molecules has been found to be more stable than the orientation perpendicular to the graphene layer. In the cases of F$_2$, Br$_2$ and I$_2$ we also found an ionic contribution to the binding energy, slowly vanishing with distance. Analysis of the electronic structure shows that ionic interaction arises due to the charge transfer from graphene to the molecules. Furthermore, we found that the increase of impurity concentration leads to the conduction band formation in graphene due to interaction between halogen molecules. In addition, graphite intercalation by halogen molecules has been investigated. In the presence of halogen molecules the binding between graphite layers becomes significantly weaker, which is in accordance with the results of recent experiments on sonochemical exfoliation of intercalated graphite.

description: Using a source selection biased towards high mass star forming regions, we used a Large Velocity Gradient (LVG) code to calculate the H2 densities and CS column densities for a sample of Midcourse Space Experiment (MSX) 8 micron infrared dark cores. Our average H2 density and CS column density were 1.14 x 10e6 cm-3 and 1.21 x 10e13 cm-2 respectively. In addition, we have calculated the Jeans mass and Virial mass for each core to get a better understanding of their gravitational stability. We found that core masses calculated from observations of N2H+ J = 1-0 and C18O J = 1-0 by Ragan et al. 2006 (Paper 1) were sufficient for collapse, though most regions are likely to form protoclusters. We have explored the star-forming properties of the molecular gas within our sample and find some diversity which extends the range of infrared dark clouds from very the massive clouds that will create large clusters, to clouds that are similar to some of our local counterparts (e.g. Serpens, Ophiuchus).

description: Eigenvalues and eigenvectors of non-Hermitian tridiagonal periodic random matrices are studied by means of the Hatano-Nelson deformation. The deformed spectrum is annular-shaped, with inner radius measured by the complex Thouless formula. The inner bounding circle and the annular halo are stuctures that correspond to the two-arc and wings observed by Hatano and Nelson in deformed Hermitian models, and are explained in terms of localization of eigenstates via a spectral duality and the Argument principle.

description: Фибрилляция предсердия (ФП) выступает одним из серьезных причин развития осложнений у пациентов с перенесенным мозговым инсультом. Метаанализ ряда исследований свидетельствует, что у пациентов с ФП и мозговым инсультом/ транзиторной ишемической атакой (ТИА) риск повторного инсульта увеличивается в 2,5 раза. Согласно современным рекомендациям (ESC 2016), для вторичной профилактики инсульта у пациентов с ФП следует выбрать эффективный новый оральный антикоагулянт (НОАК) и предпринять меры по обеспечению приверженности к терапии. У пациентов с инсультом/ ТИА в анамнезе новый НОАК снижал сердечно-сосудистую смертность и характеризовался меньшим риском больших кровотечений и внутричерепного кровотечения по сравнению с антагонистами витамина К. В обзорной статье представле ны правила применения, сроки начала/возобновления и ограничения НОАК.

description: The distribution of people and infrastructure in North American cities is not random, nor is it equitable. Minoritized communities often have less access to trees and forests and to the benefits that they provide. This pattern has developed over centuries. North American cities were built on indigenous land, and the location of rivers, wetlands, forests, and prairies influenced where houses were built, factories erected, parks sited, and where natural areas were preserved. As people moved to cities, wealthier individuals could afford to buy homes in places that they found more desirable. These places often were near parks or lakes and often had more trees. Less wealthy people could only afford homes in places that had less green infrastructure and places that were nearer to environmental harms like polluting industries. Unfortunately, in the United States, wealth is associated with race, meaning that from an early time its cities were segregated. As cities expanded and migration from the Jim Crow South and immigration from Eastern Europe increased, these wealthier, whiter communities restricted non-white people from moving into them with racist covenants and through redlining, deepening segregation. In this dissertation, I explored how this ecological and social history affected the ecology of a metropolitan region’s forests, and how that related to who gets to experience them. I also showed how the associations between socio-demographic variables and tree canopy varied across an urban to exurban region. Finally, I identified barriers to requesting and planting trees that residents experience and strategies that may help governments and strategies that may help overcome them. I found that communities of color had less access to forests that have a higher capacity to provide ecosystem services; that while segregation existed in urban, suburban, and exurban communities, canopy inequity did not; and that managing existing trees and working with neighborhood associations is the best way to encourage planting and stewardship of trees that can reduce tree equity.

description: Цель. Исследование артериального давления (АД) и геометрии сердца у спортсменов тяжелых весовых категорий силовых видов спорта. Материалы и методы. Были обследованы 645 представителей силовых видов спорта (тяжелая атлетика, пауэрлифтинг, бодибилдинг), имеющих спортивную квалификацию КМС, МС, МСМК со средней массой тела 102,7±6,4 кг. Всем обследованным спортсменам наряду с осмотром проводилась стандартная электрокардиограмма покоя, двукратное измерение АД, трансторакальная эхокардиография. Результаты. Обследование 645 спортсменов силовых видов спорта тяжелых весовых категорий показало, что 238 (37%) атлетов имеют повышенное АД (систолическое АД-157,4±5,6, диастолическое АД-91,2±5,3) и нарушение геометрии левого желудочка (ЛЖ). Достоверно у гипертензивных спортсменов, по сравнению с нормотензивными атлетами, были увеличены следующие параметры сердца: толщина межжелудочковой перегородки в диастоле на 0,1 мм (p<0,01), толщина задней стенки ЛЖ на 0,2 мм (p<0,01), диаметр правого желудочка на 4,2 мм (p<0,01), масса миокарда ЛЖ на 32,2 г (p<0,01), индекс массы миокарда ЛЖ на 17,8 г/м2 (p<0,01), относительная толщина стенки ЛЖ на 0,08 мм (p<0,01). А также в группе гипертензивных спортсменов был достоверно меньшим конечный диастолический диаметр ЛЖ на 0,2 мм (p<0,05). Заключение. Таким образом, закономерности, полученные в отношении ассоциаций АД и нарушений геометрии сердца спортсменов силовых видов спорта, тяжелых весовых категорий, могут служить научной основой для формирования некоторых аспектов профилактической программы с приоритетной ориентацией на «рискогенные» группы мужчин.
