description: We compute the difference in decay widths of charged and neutral ρ(770) vector mesons. The isospin breaking arising from mass differences of neutral and charged πand ρmesons, radiative corrections to ρ-> ππ, and the ρ-> ππγdecays are taken into account. It is found that the width difference ΔΓ_rho is very sensitive ot the isospin breaking in the $ρ$ meson mass Δm_ρ. This result can be useful to test the correlations observed between the values of these parameters extracted from experimental data.

description: An improvement in Silicon ablation by lasers is achieved when laser ablation takes place under a thin liquid
film. Therefore it is necessary to investigate the effects of the liquid on the silicon surface during laser irradiation. Different
types of microstructures observed on the silicon [100]-surface of a Si-wafer after nanosecond-pulsed laser irradiation under
liquid films of molecular solvents are presented to complete our understanding of the Laser Chemical Processing (LCP).
Water and perfluorocarbons (PFCs) are hitherto employed as liquid media due to their high thermal and chemical stability in
the LCP. Here we report on results obtained with a new reactor that allows studying the stability of solvents occurring during
the laser irradiation and the effects of solvents on the silicon surface during and after laser irradiation.

description: The 4.8 GHz lightcurves of the scintillating intra-day variable quasar J1819+3845 during 2004-5 exhibit sharp structure, down to a time scale of 15 minutes, that was absent from lightcurves taken prior to this period and from the 2006 lightcurves. Analysis of the lightcurve power spectra show that the variations must be due to the emergence of new structure in the source. The power spectra yield a scattering screen distance of 3.8 +/- 0.3 pc for a best-fit v_ISS=59 +/- 0.5 km/s or 2.0 +/- 0.3 pc for the scintillation velocity reported by Dennett-Thorpe & de Bruyn (2003). The turbulence is required to be exceptionally turbulent, with C_N^2 > 0.7 Delta L_pc^{-1} m^{-20/3} for scattering material of thickness Delta L_{pc} pc along the ray path. The 2004 power spectrum can be explained in terms of a double source with a component separation 240 +/- 15 microas in 2004.

description: Recognizing the importance of incorporating gender dimension into any development and conservation programs, gender analysis has become an important input in decision making that gives particular attention to sustainability of the programs. Using the case of Masinloc, Zambales, this study identifies the roles of men and women in the coastal resource management (CRM) and estimates the value of time spent by men and women in CRM activities. Gender-segregated data were gathered from 50 households where husband and wife from each household were separately and simultaneously interviewed using the same set of questionnaire, thus making a total of 100 respondents. Results of the analysis show that incorporating gender dimension into CRM research study affects the outcomes. Logit analysis shows that gender, awareness of the CRM activities and membership in organization significantly affect the decision to participate in CRM activities. On the other hand, the Tobit regression analysis shows that gender, household income, awareness about the CRM and membership in an organization affect the time devoted to and value of time spent in CRM activities. From the results, recommendations on how to incorporate gender dimension in CRM activities are forwarded
Empirical comparison between autoencoders and traditional dimensionality reduction methods

Year: 2021
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: In order to process efficiently ever-higher dimensional data such as images, sentences, or audio recordings, one needs to find a proper way to reduce the dimensionality of such data. In this regard, SVD-based methods including PCA and Isomap have been extensively used. Recently, a neural network alternative called autoencoder has been proposed and is often preferred for its higher flexibility. This work aims to show that PCA is still a relevant technique for dimensionality reduction in the context of classification. To this purpose, we evaluated the performance of PCA compared to Isomap, a deep autoencoder, and a variational autoencoder. Experiments were conducted on three commonly used image datasets: MNIST, Fashion-MNIST, and CIFAR-10. The four different dimensionality reduction techniques were separately employed on each dataset to project data into a low-dimensional space. Then a k-NN classifier was trained on each projection with a cross-validated random search over the number of neighbours. Interestingly, our experiments revealed that k-NN achieved comparable accuracy on PCA and both autoencoders' projections provided a big enough dimension. However, PCA computation time was two orders of magnitude faster than its neural network counterparts.

description: We study B0->rho0rho0 decays in a sample of 465*10^6 Upsilon (4S)->BBbar events collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider located at the Stanford Linear Accelerator Center (SLAC). We measure the branching fraction B = (0.92 +/- 0.32 +/- 0.14)*10^{-6} and longitudinal polarization fraction f_L = 0.75^{+0.11}_{-0.14} +/- 0.04, where the first uncertainty is statistical and the second is systematic. The evidence for the B0->rho0rho0 signal has a significance of 3.1 standard deviations, including systematic uncertainties. We investigate the proper-time dependence of the longitudinal component in the decay and measure the CP-violating coefficients S^{00}_L = (0.3 +/- 0.7 +/- 0.2) and C^{00}_L = (0.2 +/- 0.8 +/- 0.3). We study the implication of these results for the unitarity triangle angle alpha.

Corruption and market competition. From macro to micro: a critical review
Creators: name: Di Giorno, Saverio
Publisher: name: Annali del Dipartimento di metodi e modelli per l'economia, il territorio e la finanza
Year: 2025

description: This study critically reviews the relationship between corruption and competition, offering a unique perspective compared to previous reviews by examining theoretical assumptions, observation units, and data over different periods. The research identifies four major periods, beginning with the 1960s and development theory when corruption is “grease in the wheel”. The second period, starting in the 1990s, adopts an institutionalist approach, viewing corruption as rent-seeking. The third period focuses on objective measures at the regional level and the last on microlevel analysis. The review highlights differences in findings based on space scale and lack of research on time trends with respect to differences in levels. The study emphasizes the importance of extendible measures and definitions, especially at the local level. Ultimately, it suggests critical tools and open research questions for future analysis aimed at identifying and combating corruption more effectively.

description: Color centers in hexagonal boron nitride (hBN) are becoming an increasingly important building block for quantum photonic applications. Herein, we demonstrate the efficient coupling of recently discovered spin defects in hBN to purposely designed bullseye cavities. We show that the all monolithic hBN cavity system exhibits an order of magnitude enhancement in the emission of the coupled boron vacancy spin defects. In addition, by comparative finite difference time domain modelling, we shed light on the emission dipole orientation, which has not been experimentally demonstrated at this point. Beyond that, the coupled spin system exhibits an enhanced contrast in optically detected magnetic resonance readout and improved signal to noise ratio. Thus, our experimental results supported by simulations, constitute a first step towards integration of hBN spin defects with photonic resonators for a scalable spin photon interface.

description: We present homogenization of the dopant profile of emitter using double scan laser doping (LD) for
textured mono-crystalline silicon solar cell. As low cost and high efficiency solar cell, LD has much attention in
recent years. LD can form impurity distribution at low cost and in high throughput because it can be operated in
atmosphere and at room temperature. In addition, the two-dimensionally-controlled doping area can be formed easily
without using the conventional photolithography process (1-3). Especially, the continuous wave (CW) laser that we use
can make well-depth-controlled doping profile (4). However, the cratered defects were generated after LD and reduced
Voc, if substrate applied to LD had surface unevenness. In this study, the minority carrier inhomogeneity was
improved by using double scan LD in textured silicon. For LD, the phosphorous silica glass (PSG) was made by spincoating
onto the alkali-textured silicon substrate. The 532 nm wavelength Nd: YVO4 laser was scanned on the whole
surface area. As the result, we achieved improvement of minority carrier homozenization that was observed in EBIC
measurement, and reduction of sheet resistance from 200 ohm/ to 10 ohm/.

description: The study uses the 2006 to 2009 Labor Force Surveys (LFS) to estimate the wage structure and wage differentials between employed men and women in agriculture-based employment in the Philippines. Estimates reveal that average male wage workers in the agriculture sector receive remunerations that are approximately 13% to 18% higher than what the average female wage workers receive. Using the threefold Blinder-Oaxaca wage decomposition method, about 12% of the estimated gender wage gap is due to the endowment effect or the human capital effect, 74% is due to the coefficients effect and 14% can be attributed to the interaction effect.

Numerical procedure for potential flow problems with a free surface
Creators: name: Chan, Johnson Lap-Kay
Publisher: name: University of British Columbia
Year: 2010

description: A numerical procedure based upon a boundary integral method for gravity wave making problems is studied in the time domain. The free-surface boundary conditions are combined and expressed in a Lagrangian notation to follow the free-surface particle's motion in time. The corresponding material derivative term is approximated by a finite difference expression, and the velocity terms are extrapolated in time for the completion of the formulations. The fluid-body intersection position at the free surface is predicted by an interpolation function that requires information from both the free surface and the submerged surface conditions. Solutions corresponding to a linear free-surface condition and to a non-linear free-surface condition are obtained at small time increment values. Numerical modelling of surface wave problems is studied in two dimensions and in three dimensions. Comparisons are made to linear analytical solutions as well as to published experimental results. Good agreement between the numerical solutions and measured values is found. For the modelling of a three dimensional wave diffraction problem, results at high wave amplitude are restricted because of the use of quadrilateral elements. The near cylinder region of the free surface is not considered to be well represented because of the coarse element size. Wave forces calculated on the vertical cylinder are found to be affected by the modelled tank length. When the simulated wave length is comparable to the wave tank's dimension, numerical results are found to be less than the experimental measurements. However, when the wave length is shorter than the tank's length, solutions are obtained with very good precision.

description: IBS and INES have recently demonstrated the strong relevance of the plasma-immersion ion
implantation (PIII) technique to realize high efficiency silicon solar cells. The fabrication process, developed on
239cm² p-type Cz-Si wafers, gives performances similar to those of classical ion beam implantation, with an
efficiency improvement of at least 0.7% absolute with respect to classical POCl3-based emitters and that, without
deepened optimizations. Repeatability and robustness of the developed process have been validated. We give some
information describing the different steps to achieve the homogeneous n-emitters by pulsed-PIII and present
characterization results showing which cell parameters are better than that of standard cells. Both high throughput and
low cost of the immersion-plasma equipment would seriously challenge technologies developed by other companies
in the ion-implantation field devoted to the PV market. Investigations to realize BSF, selective emitters or IBC cells
by this technique are now included in the roadmap.

important factors influence on the surface area and morphology of nanostructures. The crystallinity of ZnO
nanostructures were improved after regrowth process in Mist CVD. The obtained novel ZnO nanostructures with
larger surface area are expected to be used as photo electrode instead of TiO2 in the dye-sensitized solar cell in the
future.

Mirror dark matter and the new DAMA/LIBRA results: A simple explanation for a beautiful experiment

description: Recently, the DAMA/LIBRA experiment has convincingly confirmed the DAMA/NaI annual modulation signal, experimentally demonstrating the existence of non-baryonic dark matter in the halo of our galaxy. Meanwhile, in another part of town, other experiments such as CDMS and XENON10 have not detected any evidence for dark matter. One promising dark matter candidate which can reconcile the positive DAMA annual modulation signal with the null results from the other experiments, is mirror dark matter. We re-analyse the mirror matter interpretation of the DAMA annual modulation signal utilizing a) the new data from DAMA/LIBRA, including the measured energy dependence of the annual modulation signal b) an updated quenching factor which takes into account the channeling effect in $NaI$ crystals and c) the latest constraints from CDMS/Ge, CDMS/Si and XENON10 experiments. We show that the simplest possibility of a $He'$ (and/or $H'$) dominated halo with a small $O'$ component is sufficient to fully explain all of the dark matter experiments. We also point out that a certain class of hidden sector dark matter models, although theoretically less appealing and less constrained, can mimic the success of the mirror dark matter model and hence are also viable.

description: We present single-mode nanowire (NW) lasers with ultralow threshold in the near-infrared spectral range. To ensure the single-mode operation, the NW diameter and length are reduced specifically to minimize the longitudinal and transverse modes of the NW cavity. Increased optical losses and reduced gain volume by the dimension reduction are compensated by excellent NW morphology and InGaAs/GaAs multi-quantum disks. At 5 K, a threshold low as 1.6 μJ/cm2 per pulse is achieved with a resulting quality factor exceeding 6400. By further passivating the NW with an AlGaAs shell to suppress surface non-radiative recombination, single-mode lasing operation is obtained with a threshold of only 48 μJ/cm2 per pulse at room temperature with a high characteristic temperature of 223 K and power output of ~ 0.9 μW. These single-mode, ultralow threshold, high power output NW lasers are promising for the development of near-infrared nanoscale coherent light sources for integrated photonic circuits, sensing, and spectroscopy.

This alternative has the technical advantages to be less sensitive to absolute temperature and not downward frequency limited. At INRiM the high frequency power standards are now based on coaxial thermocouples from dc to 34 GHz. Modified commercial thermocouple mounts in 7 mm and 3.5 mm coaxial line are used to realize the national power standard with an accuracy ranging from 0.03 % to 1 % in the mentioned frequency range.

description: We present a class of new explicit and stable numerical algorithms to solve the spatially discretized linear heat or diffusion equation. After discretizing the space and the time variables like conventional finite difference methods, we do not approximate the time derivatives by finite differences, but use constant neighbor and linear neighbour approximations to decouple the ordinary differential equations and solve them analytically. During this process, the timestep-size appears not in polynomial, but in exponential form with negative exponents, which guarantees stability. We compare the performance of the new methods with analytical and numerical solutions. According to our results, the methods are first and second order in time and can be much faster than the commonly used explicit or implicit methods, especially in the case of extremely large stiff systems.

description: Crystalline silicon solar modules at outdoor exposure may show the so called snail trail effect, which
appears as brownish discolored contact fingers on cell edges and/or micro cracks. In the study presented here we investigated
silicon solar modules with snail trails on microstructural scale to clear up their chemical and structural
properties. For this purpose a TEM lamella was prepared by the FIB technique on discolored EVA which was in contact
before with a discolored contact finger. To analyze the chemical components of the discolored EVA, EDX mappings
and ToF-SIMS measurements on discolored and reference EVA were performed. Cross sections at the Ag contact
finger prepared by FIB provide an insight into microstructural details. It turns out, that the snail trail effect is correlated
with Ag containing particle clusters which diffuse and agglomerate through the EVA polymer. Further chemical
components probably being involved in the chemical reactions were identified.

Role of Quarks in Nuclear Structure

description: The strong force that binds atomic nuclei is governed by the rules of Quantum Chromodynamics. Here we consider the suggestion the internal quark structure of a nucleon will adjust self-consistently to the local mean scalar field in a nuclear medium and that this may play a profound role in nuclear structure. We show that one can derive an energy density functional based on this idea, which successfully describes the properties of atomic nuclei across the periodic table in terms of a small number of physically motivated parameters. Because this approach amounts to a new paradigm for nuclear theory, it is vital to find ways to test it experimentally and we review a number of the most promising possibilities.

description: We present new spectroscopic observations of the most distant X-ray selected galaxy cluster currently known, XMMXCS J2215.9-1738 at z=1.457, obtained with the DEIMOS instrument at the W. M. Keck Observatory, and the FORS2 instrument on the ESO Very Large Telescope. Within the cluster virial radius, as estimated from the cluster X-ray properties, we increase the number of known spectroscopic cluster members to 17 objects, and calculate the line of sight velocity dispersion of the cluster to be 580+/-140 km/s. We find mild evidence that the velocity distribution of galaxies within the virial radius deviates from a single Gaussian. We show that the properties of J2215.9-1738 are inconsistent with self-similar evolution of local X-ray scaling relations, finding that the cluster is underluminous given its X-ray temperature, and that the intracluster medium contains ~2-3 times the kinetic energy per unit mass of the cluster galaxies. These results can perhaps be explained if the cluster is observed in the aftermath of an off-axis merger. Alternatively, heating of the intracluster medium through supernovae and/or Active Galactic Nuclei activity, as is required to explain the observed slope of the local X-ray luminosity-temperature relation, may be responsible.

description: The paper considers parabolic equations in non-divergent form with discontinuous coefficients at higher derivatives. Their investigation is most complicated because, in general, in the case of discontinuous coefficients, the uniqueness of a solution for nonlinear parabolic or elliptic equations can fail, and there is no a priory estimate for partial derivatives of a solution. In this paper, existence and regularity results are obtained under some Cordes type restrictions on the coefficients. The results are applied to diffusion processes.

As a regularization, this paper formulates the notion of numerical factorization based on the geometry of polynomial spaces and the stratification of factorization manifolds. Furthermore, this paper establishes the existence, uniqueness, Lipschitz continuity, condition number, and convergence of the numerical factorization to the underlying exact factorization, leading to a robust and efficient algorithm with a MATLAB implementation capable of accurate polynomial factorizations using floating point arithmetic even if the coefficients are perturbed.

description: Excerpts from the report: Climate and geographic location give the Republic of South Africa a favorable marketing advantage in world trade. Because the harvest season occurs early in the calendar year, the Republic is able to provide fresh deciduous and citrus fruit to major international markets--particularly in Western Europe--when prices are seasonally high. The Republic of South Africa's agricultural exports compete with those of the United States in the same major world or foreign markets. The United Kingdom is by far the leading customer for South African agricultural commodities. Other nations that buy significant amounts of South Africa's exports are West Germany, Japan, Italy, and--to a lesser degree--other western European countries. During 1960-65, the base period of the study, South Africa received 82 percent of its rice imports, 43 percent of its cotton imports, and 17 percent of its wheat imports from the United States. The United States was the chief supplier of both rice and cotton and ranked third as a supplier of wheat.

description: A new approach to the identification problem of linear continuous-time time-invariant systems from input-output measurements is presented. Both parametric and nonparametric system models are considered. The new approach is based on the use of continuous-time functions, the modal functions, defined in terms of the system output, the output derivatives and the state variables under the assumption that the order n of the observable system is known a priori. The modal functions are obtained by linear filtering operations of the system output, the output derivatives and the state variables so that the modal functions are independent of the system instantaneous state. In this case, the modal functions are linear functions of the input exponential modes, and they contain none of the system exponential modes unlike the system general response which contains modes from both the system and the input. The filters parameters, the modal parameters are estimated using linear regression techniques. The modal functions and the modal parameters of the output and its derivatives are used to identify parametric input-output and state models of the system. The coefficients of the system characteristic polynomial are obtained by solving n algebraic equations formed from the estimates of the modal parameters. Estimates of the parameters associated with the system zeros are obtained by solving another set of linear algebraic equation. The system frequency response and step response are estimated using the output modal function. The impulse response is obtained by filtering the estimated step response using the output first derivative modal parameters. A new method is presented to obtain the system poles as the eigenvalues of a data matrix formed from the system free response. The coefficients of the system characteristic polynomial are obtained from the data matrix through a simple recursive equation. This method has some important advantages over the well known Prony's method. The state modal functions are used to obtain a minimum-time observer that gives the continuous-time system state as a direct function of input-output samples in n sampling intervals.

description: AbstractThe electrochemical thermodynamic and kinetic characteristics of rechargeable batteries are critically influenced by the ordering of mobile ions in electrodes or solid electrolytes. However, because of the experimental difficulty of capturing the lighter migration ion coupled with the theoretical limitation of searching for ordered phases in a constrained cell, predicting stable ordered phases involving cell transformations or at extremely dilute concentrations remains challenging. Here, a group-subgroup transformation method based on lattice transformation and Wyckoff-position splitting is employed to predict the ordered ground states. We reproduce the previously reported Li0.75CoO2, Li0.8333CoO2, and Li0.8571CoO2 phases and report a new Li0.875CoO2 ground state. Taking the advantage of Wyckoff-position splitting in reducing the number of configurations, we identify the stablest Li0.0625C6 dilute phase in Li-ion intercalated graphite. We also resolve the Li/La/vacancy ordering in Li3xLa2/3−xTiO3 (0 < x < 0.167), which explains the observed Li-ion diffusion anisotropy. These findings provide important insight towards understanding the rechargeable battery chemistry.

description: BACKGROUND: Patient and Public Involvement (PPI) in health and social care research is increasingly prevalent and is promoted in policy as a means of improving the validity of research. This also applies to people living in prison and using social care services. Whilst evidence for the effectiveness of PPI was limited and reviews of its application in prisons were not found, the infancy of the evidence base and moral and ethical reasons for involvement mean that PPI continues to be advocated in the community and in prisons. OBJECTIVES: To conduct a review of the literature regarding the involvement of people or persons living in prison (PLiP) in health and social care research focused on: (i) aims; (ii) types of involvement; (iii) evaluations and findings; (iv) barriers and solutions; and (v) feasibility of undertaking a systematic review. METHODS: A systematic scoping review was undertaken following Arksey and O'Malley's (International Journal of Social Research Methodology 8: 19-32, 2005) five-stage framework. A comprehensive search was conducted involving ten electronic databases up until December 2020 using patient involvement and context related search terms. A review-specific spreadsheet was created following the PICO formula, and a narrative synthesis approach was taken to answer the research questions. PRISMA guidelines were followed in reporting. RESULTS: 39 papers were selected for inclusion in the review. The majority of these took a 'participatory' approach to prisoner involvement, which occurred at most stages during the research process except for more 'higher' level research operations (funding applications and project management), and only one study was led by PLiPs. Few studies involved an evaluation of the involvement of PLiP, and this was mostly PLiP or researcher reflections without formal or independent analysis, and largely reported a positive impact. Barriers to the involvement of PLiP coalesced around power differences and prison bureaucracy. CONCLUSION: Given the very high risk of bias arising from the available 'evaluations', it was not possible to derive firm conclusions about the effectiveness of PLiP involvement in the research process. In addition, given the state of the evidence base, it was felt that a systematic review would not be feasible until more evaluations were undertaken using a range of methodologies to develop the field further.

description: BACKGROUND: Stem cell-based therapies for neurodegenerative diseases like Parkinson's disease are a promising approach in regenerative medicine and are now moving towards early stage clinical trials. However, a number of challenges remain including the ability to grow stem cells in vitro on a 3-dimensional scaffold, as well as their loss, by leakage or cell death, post-implantation. These issues could, however, be helped through the use of scaffolds that support the growth and differentiation of stem cells both in vitro and in vivo. The present study focuses on the use of bacterial cellulose as an in vitro scaffold to promote the growth of different stem cell-derived cell types. Bacterial cellulose was used because of its remarkable properties such as its wettability, ability to retain water and low stiffness, all of which is similar to that found in brain tissue. METHODS: We cultured human embryonic stem cell-derived progenitor cells on bacterial cellulose with growth factors that were covalently functionalised to the surface via silanisation. Epifluorescence microscopy and immunofluorescence were used to detect the differentiation of stem cells into dopaminergic ventral midbrain progenitor cells. We then quantified the proportion of cells that differentiated into progenitor cells and compared the effect of growing cells on biofunctionalised cellulose versus standard cellulose. RESULTS: We show that the covalent functionalisation of bacterial cellulose sheets with bioactive peptides improves the growth and differentiation of human pluripotent stem cells into dopaminergic neuronal progenitors. CONCLUSIONS: This study suggests that the biocompatible material, bacterial cellulose, has potential applications in cell therapy approaches as a means to repair damage to the central nervous system, such as in Parkinson's disease but also in tissue engineering.

description: Proportional to the growth in the usage of Human Sensor Networks (HSN), the volume of the data exchange between Sensor devices is increasing at a rapid pace. In this paper, we have proposed an Energy Efficient Lightweight Encryption (EELWE) algorithm for providing the confidentiality of data at the sensor level, particularly suitable for resource-constrained environments. Results obtained have proved that an EELWE consumes less energy relative to present lightweight ciphers and it supports multiple block sizes of 32-bit, 48-bit, and 64-bit.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3727-3730
description: Over the last two years, hardware component prices for solar photovoltaic electrical generation systems
have decreased by more than 50%. At these levels in sunny regions a PV module offers the cheapest possibility of all
to generate DC electricity. For full systems, a simple LCOE analysis has been applied to illustrate the competiveness
of PV electricity compared to household electricity in many EU countries. The goal of 20% renewable energy in
Europe by 2020 can probably be achieved at lower costs and higher PV share than anticipated in 2010. For
households these developments, together with the advent of affordable battery storage, opens a range of possibilities
for exploiting PV in an economically feasible way.
