description: It is already reported in the literature that the performance of a machine learning algorithm is greatly impacted by performing proper Hyper-Parameter optimization. One of the ways to perform Hyper-Parameter optimization is by manual search but that is time consuming. Some of the common approaches for performing Hyper-Parameter optimization are Grid search Random search and Bayesian optimization using Hyperopt. In this paper, we propose a brand new approach for hyperparameter improvement i.e. Randomized-Hyperopt and then tune the hyperparameters of the XGBoost i.e. the Extreme Gradient Boosting algorithm on ten datasets by applying Random search, Randomized-Hyperopt, Hyperopt and Grid Search. The performances of each of these four techniques were compared by taking both the prediction accuracy and the execution time into consideration. We find that the Randomized-Hyperopt performs better than the other three conventional methods for hyper-paramter optimization of XGBoost.

description: WITCH is an energy-economy-climate model developed by the climate change group at FEEM. The model has been extensively used in the past 3 years for the economic analysis of climate change policies. WITCH is a hybrid top-down economic model with a representation of the energy sector of medium complexity. Two distinguishing features of the WITCH model are the representation of endogenous technological change and the game–theoretic set-up. Technological change is driven by innovation and diffusion processes, both of which feature international spillovers. World countries are grouped in 12 regions which interact with each other in a setting of strategic interdependence. This paper describes the updating of the base year data to 2005 and some new features: the inclusion of non-CO2 greenhouse gases and abatement options, the new specification of low carbon technologies and the inclusion of reducing emissions from deforestation and degradation.

description: We analyse here the problem of large deformation of dielectric elastomeric membranes under coupled electromechanical loading. Extremely large deformations (enclosed volume changes of 100 times and greater) of a toroidal membrane are studied by the use of a variational formulation that accounts for the total energy due to mechanical and electrical fields. A modified shooting method is adopted to solve the resulting system of coupled and highly nonlinear ordinary differential equations. We demonstrate the occurrence of limit point, wrinkling, and symmetry-breaking buckling instabilities in the solution of this problem. Onset of each of these "reversible" instabilities depends significantly on the ratio of the mechanical load to the electric load, thereby providing a control mechanism for state switching.

subject: Community-based Industries

description: The industrial organization of developing countries is characterized by the pervasive use of subcontracting arrangements among small, financially constrained firms. This paper asks whether vertical integration relaxes those financial constraints. It shows that vertical integration trades off the benefits of joint liability against the costs of rendering the supply chain more opaque to external investors. In contrast to the commonly held view that pervasive input and capital market imperfections are conducive to vertical integration, the model predicts that the motives for vertical integration are not necessarily higher in developing countries. In particular, vertical integration is more likely to arise at intermediate levels of investor protection and better contract enforcement with suppliers reduces vertical integration only if financial markets are sufficiently developed. Evidence supporting both predictions is discussed.

description: We present the results of the detailed experimental study of multiple ionization of Ne and Ar by 25 and 7 fs laser pulses. For Ne the highly correlated "instantaneous" emission of up to four electrons is triggered by a recollisional electron impact, whereas in multiple ionization of Ar different mechanisms, involving field ionization steps and recollision-induced excitations, play a major role. Using few-cycle pulses we are able to suppress those processes that occur on time scales longer than one laser cycle.

description: This study has permitted to generate data on which the RID serious game can operate. It consists of studying getting around in Garnd Paris area. The ideal goal of people who travel in Grand Paris is to do so quickly, safely, comfortably and cheaply with little or no environmental impact. The study began with an in-depth literature review of mobility practices in major Western megacities. From this, a cognitive model has been developed with 9 user profiles, 9 usage situations, 9 problems and 9 existing solutions. The RID comparator has highlighted that Elderly travelers and Disabled travelers were poorly served. Two corresponding value buckets are expressed from this point. A dreamt usage scenario is imagined as well as a Product-Service-Organization architecture of a smartphone application allowing to facilitate the preparation and the follow-up of journeys for elderly and disabled people.

description: We study the structural differences among climate change leading ‘factors’ - Northern EU members -, and lagging actors - southern EU countries and the ‘Umbrella group’ - with regard to long run carbon-income relationships. Homogeneous and heterogeneous panel models show that the groups of countries less in favour of stringent climate policy have yet to experience a Kuznets curve, though they show relative delinking. Northern EU instead robustly shows bell shapes. Exogenous policy events such as the 1992 climate change convention appear to be relevant in shaping the EKC of Northern EU. In addition, other events such as the second oil price shock appear to have also impacted in shaping the long run emission/GDP dynamics.

description: The planned sensitivity upgrades to the LIGO and Virgo facilities could uniquely identify host galaxies of dark sirens-compact binary coalescences without any electromagnetic counterparts-within a redshift of z = 0.1. This is aided by the higher order spherical harmonic modes present in the gravitational-wave signal, which also improve distance estimation. In conjunction, sensitivity upgrades and higher modes will facilitate an accurate, independent measurement of the host galaxy's redshift in addition to the luminosity distance from the gravitational wave observation to infer the Hubble-Lemaître constant H0 to better than a few percent in five years. A possible Voyager upgrade or third generation facilities would further solidify the role of dark sirens for precision cosmology in the future.

description: For mathematical models of quantum wave guides we show that in some situations two interacting particles can be trapped more easily than a single particle. In particular, we give an example of a wave guide that can not bind a single particle, but does have a geometrically induced bound state for two particles that attract each other. We also show that Neumann boundary conditions are `stickier' for two interacting particles than for a single one.

The spectra of baryons composed of the same quarks is studied using the same model. The results and the limitations of this approach are described. Some possible improvements are suggested.

description: We derive the Boltzmann equation for scalar fields using the Schwinger-Keldysh formalism. The focus lies on the derivation of the collision term. We show that the relevant self-energy diagrams have a factorization property. The collision term assumes the Boltzmann-like form of scattering probability times statistical factors for those self-energy diagrams which correspond to tree level scattering processes. Our proof covers scattering processes with any number of external particles, which come from self-energy diagrams with any number of loops.

description: Many physical systems can be mapped onto solved or "solvable" models of magnetism. In this work, we have mapped the statistical mechanics of columnar phases of ideally helical rigid DNA -- subject to the earlier found unusual, frustrated pair potential [A. A. Kornyshev and S. Leikin, J. Chem. Phys. 107, 3656 (1997)] -- onto an exotic, unknown variant of the XY model on a fixed or restructurable lattice. Here the role of the 'spin' is played by the azimuthal orientation of the molecules. We have solved this model using a Hartree-Fock approximation, ground state calculations, and finite temperature Monte Carlo simulations. We have found peculiar spin order transitions, which may also be accompanied by positional restructuring, from hexagonal to rhombohedric lattices. Some of these have been experimentally observed in dense columnar aggregates. Note that DNA columnar phases are of great interest in biophysical research, not only because they are a useful in vitro tool for the study of DNA condensation, but also since these structures have been detected in living matter. Within the approximations made, our study provides insight into the statistical mechanics of these systems.

MONOLOGICAL SPEECH AS A KEY FACTOR IN SPEECH DEVELOPMENT FOR LEARNERS OF ENGLISH AS A FOREIGN LANGUAGE
Creators: name: Sharipova, Charos
Publisher: name: Zenodo
Year: 2024

description: Speech development is a vital aspect of language learning, particularly in the context of English as a foreign language (EFL). While much of the focus in communicative language teaching has been on dialogical interaction, monological speech—where a speaker engages in extended discourse—offers unique benefits for language acquisition. In the EFL classroom, the use of monological speech tasks, such as presentations, speeches, and storytelling, promotes deeper language processing and enables learners to practice language production without immediate feedback from others.

description: Resonant electric dipole-dipole interactions between cold Rydberg atoms were observed using microwave spectroscopy. Laser-cooled Rb atoms in a magneto-optical trap were optically excited to 45d Rydberg states using a pulsed laser. A microwave pulse transferred a fraction of these Rydberg atoms to the 46p state. A second microwave pulse then drove atoms in the 45d state to the 46d state, and was used as a probe of interatomic interactions. The spectral width of this two-photon probe transition was found to depend on the presence of the 46p atoms, and is due to the resonant electric dipole-dipole interaction between 45d and 46p Rydberg atoms.

description: In the $Λ$CDM model of structure formation galactic haloes build up by accretion of mass and mergers of smaller subunits. The most recent massive merger event experienced by the Milky Way (MW) halo was the accretion of the Large Magellanic Cloud (LMC; which has a stellar mass of $\sim \; 10^9M_\odot$). Recent analyses of galactic stellar data from the \textit{Gaia} satellite have uncovered an earlier massive accretion event, the Gaia-Enceladus-Sausage (GES), which merged with the MW around 10 Gyr ago. Here, we use the EAGLE cosmological hydrodynamics simulation to study properties of simulated MW-mass haloes constrained to have accretion histories similar to that of the MW, specifically the recent accretion of an "LMC" galaxy and a "GES'' merger, with a quiescent period between the GES merger and the infall of the LMC (the "GES \& LMC" class). We find that $\sim 16$ per cent of MW-mass haloes have an LMC; $\sim 5$ per cent have a GES event and no further merger with an equally massive object since $z=1$; and only $0.65$ per cent belong to the LMC \& GES category. The progenitors of the MWs in this last category are much less massive than average at early times but eventually catch up with the mean. The LMC \& GES class of galaxies naturally end up in the "blue cloud" in the colour-magnitude diagram at $z=0$, tend to have a disc morphology and have a larger than average number of satellite galaxies.

description: To show the feasibility of a long distance partial Bell-State measurement, a Hong-Ou-Mandel experiment with coherent photons is reported. Pairs of degenerate photons at telecom wavelength are created by parametric down conversion in a periodically poled lithium niobate waveguide. The photon pairs are separated in a beam-splitter and transmitted via two fibers of 25km. The wave-packets are relatively delayed and recombined on a second beam-splitter, forming a large Mach-Zehnder interferometer. Coincidence counts between the photons at the two output modes are registered. The main challenge consists in the trade-off between low count rates due to narrow filtering and length fluctuations of the 25km long arms during the measurement. For balanced paths a Hong-Ou-Mandel dip with a visibility of 47.3% is observed, which is close to the maximal theoretical value of 50% developed here. This proves the practicability of a long distance Bell state measurement with two independent sources, as e.g. required in an entanglement swapping configuration in the scale of tens of km.

Constraining Galactic Models Through Parallax and Astrometry of Microlensing Events

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: In recent years various models for the Galactic distribution of massive compact halo objects (MACHOs) have been proposed for the interpretation of microlensing toward the Large Magellanic Cloud (LMC). A direct way to fit the best model is by measuring the lens parameters, which can be obtained by measuring the Einstein crossing time and the parallax effect on the microlensing light curve and by astrometry of centroids of images. In this work, the theoretical distribution of these parameters is obtained for the various power-law Galactic dark halo models and MACHO mass functions (MF). For self-lensing as one of the models for the interpretation of LMC events, the maximum shift of image centroids and the parallax parameter are one order of magnitude smaller than for models with dark halos. This can be used as a test for the self-lensing, although the shifting of image centroids 0.02 {\it mas}, for the LMC events is unlikely to be observed by the astrometric missions such as FAME, GAIA and SIM.

description: In this paper we analyze the large genus asymptotics for intersection numbers between $ψ$-classes, also called correlators, on the moduli space of stable curves. Our proofs proceed through a combinatorial analysis of the recursive relations (Virasoro constraints) that uniquely determine these correlators, together with a comparison between the coefficients in these relations with the jump probabilities of a certain asymmetric simple random walk. As an application of this result, we provide the large genus limits for Masur-Veech volumes and area Siegel-Veech constants associated with principal strata in the moduli space of quadratic differentials. These confirm predictions of Delecroix-Goujard-Zograf-Zorich from 2019.

description: In the Starobinsky model of inflation, the observed dark matter abundance can be produced from the direct decay of the inflaton field only in a very narrow spectrum of close-to-conformal scalar fields and spinors of mass $\sim 10^7$ GeV. This spectrum can be, however, significantly broadened in the presence of effective non-renormalizable interactions between the dark and the visible sectors. In particular, we show that UV freeze-in can efficiently generate the right dark matter abundance for a large range of masses spanning from the keV to the PeV scale and arbitrary spin, without significantly altering the heating dynamics. We also consider the contribution of effective interactions to the inflaton decay into dark matter.

description: We study two body decays of a scalar glueball. We show that in QCD a spin-0 pure glueball (a state only with gluons) cannot decay into a pair of light quarks if chiral symmetry holds exactly, i.e., the decay amplitude is chirally suppressed. However, this chiral suppression does not materialize itself at the hadron level such as in decays into $π^+π^-$ and $K^+K^-$, because in perturbative QCD the glueball couples to two (but not one) light quark pairs that hadronize to two mesons. Using QCD factorization based on an effective Lagrangian, we show that the difference of hadronization into $ππ$ and $KK$ already leads to a large difference between ${\rm Br} (π^+π^-)$ and ${\rm Br}(K^+K^-)$, even the decay amplitude is not chirally suppressed. Moreover, the small ratio of $R={\rm Br}(ππ)/{\rm Br}(K\bar K)$ of $f_0(1710)$ measured in experiment does not imply $f_0(1710)$ to be a pure glueball. With our results it is helpful to understand the partonic contents if ${\rm Br}(ππ)$ or ${\rm Br}(K\bar K)$ is measured reliably.

Ethnomedicine of the Magical Papyri
Creators: name: Eldor, Ole
Publisher: name: University of British Columbia
Year: 2009

description: Many aspects of the relations among medicine and religious ideas in late antiquity remain to be explored from a fresh perspective, particularly regarding those ideas classed as so-called "magic." Much of the previous scholarship of these relations was doubly-biased by the ethnocentrism of the Western biomedical model and a traditional societal prejudice against private ritual . The successful application by John Pilch of anthropological concepts and models to the healings in the New Testament showed an ideal way for similar analyses to other texts from the same world. This study is an attempt to apply Pilch's method to the so-called "Magical Papyri" and overcome these biases. In this aim it was successful by showing that these methods do bear out on the papyri. This study proved the fruitfulness of this methodology by succeeding in highlighting a series of symbolic healings among the rituals in the corpus with aspects that under examination appear to have been a complex, powerful, and likely very effective combination of therapy and ritual that was the product of a carefully-developed traditional system. This work takes some first steps towards using the papyri to show how the medical system was related to the religious system to which it was attached in late antique Egyptian society. It shows that Egypt, perhaps unusually among traditional societies, had a class of symbolic healers who operated in the professional sector of the health care system; it thus begins to account for aspects of the healing system or systems represented in the papyri.

description: There exists a growing body of literature which looks at export decisions made by firms. Most studies focus on developed countries and do not explore whether different behavioral patterns prevail over the firm size distribution. This paper aims at filling this gap in the literature by analyzing the export behavior of a statistically representative sample of 192 Small and Medium-Size Enterprises (SMEs) in a developing country, Argentina, over the period 1996-1998. We find that the level of employment, sourcing from abroad, investment in product improvement and average productivity are associated with a higher probability of exporting. Training activities for employees are important to export outside of MERCOSUR.

description: At the Center for Scalable Data Analytics and Artificial Intelligence (ScaDS.AI) Dresden / Leipzig, we are currently developing a comprehensive training program to optimally guide science, industry, and society in general on the path into the AI age. For this purpose, we are developing and collecting training materials on topics such as the use of chat apps and language models, prompt engineering, high-performance computing, machine learning, data analysis, Python programming, and data visualization. Furthermore, in the project NFDI4BioImage, we collect and curate training materials on research data management and microscopy image analysis for life scientists. The mass of training materials (e.g., thousands of PowerPoint slides and hundreds of Jupyter notebooks) becomes both a challenge and an opportunity for AI scientists. We are working on an AI system that generates personalized training materials, tailored to specific needs and extracted from large collections of materials.

description: We present results of high-resolution experiments on single ionization of He, Ne and Ar by ultra-short (25 fs, 6 fs) 795 nm laser pulses at intensities 0.15-2.0x10^15 W/cm^2. We show that the ATI-like pattern can survive deep in the tunneling regime and that the atomic structure plays an important role in the formation of the low-energy photoelectron spectra even at high intensities. The absence of ponderomotive shifts, the splitting of the peaks and their degeneration for few-cycle pulses indicate that the observed structures originate from a resonant process.

Culture, healing and spirituality and their influence on treatment programs for aboriginal offenders

description: This study investigated the role of culture, healing and spirituality in treatment programs for Aboriginal offenders. Aboriginal people have been profoundly affected by their contact with Europeans and one negative consequence is their over-representation in the Canadian Criminal Justice System (CJS) (Chisholm, 1994). In British Columbia, Aboriginal adults constitute approximately 5% of the population, but they represent 20% of those incarcerated; Aboriginals comprise 8% of the adult population in Saskatchewan, yet they constitute 76% of incarcerated individuals (Boe, 2000). By virtue of their overrepresentation, Aboriginals present as a special interest group in the CJS. As the Correctional Services of Canada (CSC) implements a number of treatment programs that Aboriginal inmates have an opportunity to attend (CSC webpage, www.csc-scc.gc.ca), knowledge of the effectiveness of these programs is important. A total of 50 offenders participated in the study: 40 Aboriginal men and 10 non-Aboriginal men. Participants were required to fill out a research package consisting of the following components: a consent form, a background information questionnaire, a treatment/program involvement questionnaire, the Native American Acculturation Scale, and the Balanced Inventory for Desired Responding. The results of the study support prior findings (Hodgson & Heckbert, 1994; Johnston, 1997; Waldram, 1993) indicating that spirituality, culture and practicing traditions are fundamental components of treatment programs for Aboriginal offenders. More specifically, many Aboriginal participants (52%) in this sample indicated that they considered Aboriginal programs effective because of their cultural and spiritual components. Additionally, Aboriginal participants reported that healing contributed to treatment effectiveness for both Aboriginal programs (44%) and, to a lesser extent, non Aboriginal programs (18.5%). Furthermore, an encouraging discovery was that these participants reported that Aboriginal programs are, in their view, moderately (28%) to highly (40%) likely to decrease their recidivism. Additionally, Aboriginal participants also reported that they most often solicit assistance and support from Aboriginal people when experiencing personal problems (92.5%), institutional problems (85%) and consider Aboriginal people to be the most supportive people (90%). Although results indicated that it is necessary for CSC to be culturally sensitive in accommodating Aboriginal offenders, further research is required to investigate the actual, as opposed to perceived, effectiveness of current Aboriginal programs operating at CSC, as well as assisting in designing and implementing future programs and activities that are culturally appropriate.

description: The nonequilibrium behaviour of a core-shell nanoparticle has been studied by Monte- Carlo simulation. The core consists of Ising spins of $σ=1/2$ and the shell contains Ising spins of $S=1$. The interactions within the core and in the shell are considered ferromagnetic but the interfacial interaction between core and shell is antiferromagnetic. The nanoparticle system is kept in open boundary conditions and is driven by randomly varying (in time but uniform over the space) magnetic field. Depending on the width of the randomly varying field and the temperature of the system, the core, shell and total magnetization varies in such a manner that the time averages vanish for higher magnitude of the width of random field, exhibiting a dynamical symmetry breaking transitions. The susceptibilities get peaked at two different temperatures indicating nonequilibrium multiple transitions. The phase boundaries of the nonequilibrium multiple transitions are drawn in the plane formed by the axes of temperature and the width of the randomly varying field. Furthermore, the effects of the core and shell thicknesses on the multiple transitions have been discussed.

description: In many industries it is quite common to observe firms delegating the production of essential inputs to independent ventures jointly established with competing rivals. The diffusion of this arrangement and the favourable stance of competition authorities call for the assessment of the social and private desirability of Input Production Joint Ventures (IPJV), which represent a form of input production cooperation, not investigated so far. IPJV can be seen as an intermediate organizational setting lying between the two extremes of vertical integration and vertical separation. Our investigation is based on an oligopoly model with horizontally differentiated goods. We characterize the conditions under which IPJV is privately optimal finding that firms’ incentives may be welfare detrimental. We also provide a rationale for the empirical relevance of IPJV both in terms of its ability to survive and in terms of disengagement incentives.

description: This paper analyses the effects on economic agents' behaviour of an innovative environmental protection mechanism that the Public Administration of a tourist region may adopt to attract visitors while protecting the environment. On the one hand, the Public Administration sells to the tourists an environmental call option that gives them the possibility of being (partially or totally) reimbursed if the environmental quality in the region turns out to be below a given threshold level. On the other hand, it offers the firms that adopt an innovative, non-polluting technology an environmental put option that allows them to get a reimbursement for the additional costs imposed by the new technology if the environmental quality is above the threshold level. The aim of the paper is to study the dynamics that arise with this financial mechanism from the interaction between the economic agents and the Public Administration in an evolutionary game context.

description: Raman transitions are used in quantum simulations with ultracold atoms for cooling, spectroscopy and creation of artificial gauge fields. Spatial shaping of the Raman fields allows local control of the effective Rabi frequency, which can be mapped to the atomic spin. Evanescent Raman fields are of special interest as they can provide a new degree of control emanating from their rapidly decaying profile and for their ability to generate features below the diffraction limit. This opens the door to the formation of sub-wavelength spin textures. In this work, we present a theoretical and numerical study of Raman Rabi frequency in the presence of evanescent driving fields. We show how spin textures can be created by spatially varying driving fields and demonstrate a skyrmionium lattice - a periodic array of topological spin excitations, each of which is composed of two skyrmions with opposite topological charges. Our results pave the way to quantum simulation of spin excitation dynamics in magnetic materials, especially of itinerant spin models.

description: Astrophysical neutrinos at $\sim$EeV energies promise to be an interesting source for astrophysics and particle physics. Detecting the predicted cosmogenic (``GZK'') neutrinos at 10$^{16}$ - 10$^{20}$ eV would test models of cosmic ray production at these energies and probe particle physics at $\sim$100 TeV center-of-mass energy. While IceCube could detect $\sim$1 GZK event per year, it is necessary to detect 10 or more events per year in order to study temporal, angular, and spectral distributions. The IceCube observatory may be able to achieve such event rates with an extension including optical, radio, and acoustic receivers. We present results from simulating such a hybrid detector.

description: The aim of this thesis was to examine and produce an overview of the cybersecurity in 5G technology and evaluate the Remote-5G implementation of Lapland University of Applied Sciences from a cybersecurity perspective. The thesis was commissioned by Lapland University of Applied Sciences and is part of the international Agrarsense project. The thesis study explored how cybersecurity has been addressed in 5G technology, and how commercial operators have accounted for it. Also, it was examined what different standards define 5G technology and cybersecurity. One of the key research questions was to investigate the cybersecurity aspects of Lapland University of Applied Sciences Remote-5G implementation. The standards used in 5G technology, the technical structure, and how different commercial entities ensure cybersecurity were all reviewed. The aim was not to delve deeply into technical details, but to provide a broader understanding and answer the research questions. Data was collected from publicly available sources such as literature, publications, and materials found on the internet. One of the results of the study was an increased understanding for Lapland University of Applied Sciences about the cybersecurity of the Remote-5G implementation. The conclusion was that there is room for improvement in the cybersecurity of the implementation. However, the used methods were secure and functional. As a suggestion for improvement, recommendations were made for possible device solutions used in the Remote-5G setup and the implementation of specific techniques. The thesis provides an insight to the structure of 5G architecture, and the technologies used within it from a cybersecurity perspective. The 5G architecture and its standards take cybersecurity into account. Commercial operators who adopted the standards also took cybersecurity into consideration by including it as one of the design principles for their systems.

description: The objective of this paper is to determine whether the participation in social organizations, which are commonly defined as a form of social capital, represents a complement or a substitute with respect to emigration. The nature of the relationship depends on the motivations behind the two choices, which induce the households to join a group and to invest in migration. To address this research question a bivariate probit model is employed, in that the decision to migrate and to join a social organization are estimated simultaneously. Both temporary and permanent emigration of the household are addressed. The results of the empirical estimation reveal that families participating in social organizations are more likely to send siblings abroad permanently, as they may receive from the social network important information that is crucial for permanent emigration. Hence, social capital performs a role as complement to permanent emigration. On the other hand, social capital is associated with a lower probability of moving temporarily. This may indicate that families resort to social capital rather than to temporary circular migration to overcome contingent liquidity constraint and therefore social capital is a substitute for temporary emigration.
