description: Fractal analysis is carried out on the stock market indices of seven European countries and the US. We find evidence of long range dependence in the log return series of the Mibtel (Italy) and the PX Glob (Czech Republic). Long range dependence implies that predictable patterns in the log returns do not dissipate quickly, and may therefore produce potential arbitrage opportunities. Therefore, these results are in contravention of the Efficient Market Hypothesis. We show that correcting for short range dependence, or prefiltering, may dispose of genuine long range dependence, suggesting that the market is efficient in cases when it is not. Prefiltering does not reduce significantly the power of the tests only for cases for which the Hurst exponent (a measure of the long range dependence) lies well outside the boundaries of no long range dependence. For borderline cases, the prefiltering procedure reduces the power of the test. On the other hand, the absence of prefiltering does not result in a test that is significantly oversized.

description: This study examined the profitability status of small scale agribusiness enterprises with particular reference to bakeries in Bauchi metropolis. A sample, of thirty five (35) bakeries ware randomly selected as sample from the study. The Master bakers of the_ bakeries· were given structured questionnaire to collect their responses on various items of interest. Similarly,· additional information was collected using interview schedule to clarify· facts that are not properly that the total cost of production and the total revenue generated were N48,939.70 and N51,368.00 respectively; while a net profit of N2428.30 was realized from daily production. This study encourages the need for an increase in the production of goods and services through investment on small scale agribusine·ss- across the riatiori.-The encouragement of such enterprises will equally lead to a treniendous decrease· in unemployment rate by reducing the number of graduat~s that are roaming the streets of cities in Nigeria. Constraints associated with bakeries in the study area were identified to include insufficient capital outlay, spasmodic price of raw materials, illiteracy on the part of employees and language barrier. The study therefore suggest the fonnation of co-operative societies, registration of small scale business owners with supply companies to stem the fluctuation of the price of raw - materials, absorption of at least secondary school leavers coupled small __:_ scale business owners expand their production capacity at an affordable cost.·

description: We discuss the charging behavior of clays and clay minerals in aqueous electrolyte solutions. Clay platelets exhibit different charging mechanisms on the various surfaces they expose to the solution. Thus, the basal planes have a permanent charge that is typically considered to be independent of pH, whereas the edge surfaces exhibit the amphoteric behavior and pH-dependent charge that is typical of oxide minerals. Background electrolyte concentration and composition may affect these two different mechanisms of charging in different ways. To guide and to make use of these unique properties in technical application, it is necessary to understand the effects of the various master variables (i.e. pH and background salt composition and concentration). However, how to disentangle the various contributions to the charge that is macroscopically measurable via conventional approaches (i.e. electrokinetics, potentiometric titrations, etc.) remains a challenge. The problem is depicted by discussing in detail the literature data on kaolinite obtained with crystal face specificity. Some results from similar experiments on related substrates are also discussed. As an illustration of the complexity, we have carried out extensive potentiometric mass and electrolyte titrations on artificial clay samples (Na-, Ca-, and Mg-montmorillonite). A wide variety of salts was used, and it was found that the different electrolytes had different effects on the end point of mass titrations. In the case of a purified sample (i.e. no acid-base impurities), the end point of a mass titration (the plateau of pH achieved for the highest concentrations of solid), in principle, corresponds to the point of zero net proton and hydroxide consumption, at which in ideal systems, such as oxide minerals, the net proton surface charge density is zero. To such concentrated (dense) suspensions of clay particles, aliquots of salts can be added and the resulting pH indicates the specificity of a given salt for a given clay particle system. In the experimental data, some ambiguity remains, which calls for further detailed and comprehensive studies involving the application of all the available techniques to one system. Although, right now, the overall picture appears to be clear from a generic point of view (i.e. concerning the trends), clearly, in a quantitative sense, huge differences occur for nominally identical systems and only such a comprehensive study will allow to proof the current phenomenological picture and allow the next step to be taken to understand the fine details of the complex clay-electrolyte solution interfaces.

description: The Quiet Friend
 For piano, percussion and electronics For Ross Gibson composed in March 2023. 15 minutes.

 The electronics part is embedded in the score (the file with the .dsz extension), and should be played from a subwoofer under the piano, connected to the ipad via a mini jack out. The level should never overpower the instruments
 The score should be read in the Decibel ScorePlayer application on an iPad.
 PROGRAM NOTE The Quiet Friend is the sound of the piano when it resonates after the hammer strike, and this is the space where the percussion interacts with the piano, with instruments that create duration, rather than attack. The most important parts of this piece are the delicate floating sounds that slide in and out of audibility; the end of the sound, the outmost audible range of pitch and volume, and the space around it that the music cretes for us. This piece is dedicated to Ross Gibson (1956-2023), collaborator and friend in music and poetry. I wish we had met sooner. It was premiered by my incredible colleagues at Monash University, Louise Devenish and Aura Go, on International Womens Day 2023.

description: The present volume contains the proceedings of the First International Workshop on Graphical Models for Security (GraMSec'14). The workshop was held in Grenoble, France, on April 12, 2014, as one of the satellite events of the European Joint Conferences on Theory and Practice of Software 2014 (ETAPS'14). Graphical security models provide an intuitive but systematic methodology to analyze security weaknesses of systems and to evaluate potential protection measures. Such models have been subject of academic research and they have also been widely accepted by the industrial sector, as a means to support and facilitate threat analysis and risk management processes. The objective of GraMSec is to contribute to the development of well-founded graphical security models, efficient algorithms for their analysis, as well as methodologies for their practical usage. The workshop brings together academic researchers and industry practitioners designing and employing visual models for security in order to provide a platform for discussion, knowledge exchange and collaborations.

description: Mechanization has repeatedly featured in the development programme at the. two levels of government in Osun state. The inability of government to sustain the programme when previously introduced alludes to poor policy implementation.. This study therefore, assesses the tractor hire policy,in Osun state. Multi-stage sampling technique was,.used to select 266 arable crop farmers and infonnation was collected .. through questio~naire and personal inter.views. Similar tool was .used to collect information from . t~e local goyemm_ent areas (LGAs) tractor hiring unit and Osun state Agricultural Development._ Corporation (OSADEC) .. Further the data· froin the study were analysed using descriptive. statistics and a multiple linear regression 'analysis. Results revealed that, the LGAs and OSADEC control the tractor hiring market while private hire services are uncommon. About 76% of tractor hire beneficiary are real gainers while U % are nominal gainers. Tractor hour is under-µtilized which suggest inefficiency in its·allocation as a production resource. Based on these-findings it is recommended that, tr~ctor hire operators should increase access to this resource by de-emphasising political party connection ~o that the present looser can become gainers.

description: In this paper we present the results of the first systematic search for counterparts to nearby ultraluminous X-ray sources (ULXs) in the near-infrared (NIR). We observed 62 ULXs in 37 galaxies within 10 Mpc and discovered 17 candidate NIR counterparts. The detection of 17 out of 62 ULX candidates points to intrinsic differences between systems that show and those that do not show infrared emission. For six counterparts we conclude from the absolute magnitudes and - - in some cases - additional information such as morphology and previously reported photometric or spectroscopic observations, that they are likely background active galactic nuclei or ULXs residing in star clusters. Eleven counterparts have absolute magnitudes consistent with them being single red supergiant stars. Alternatively, these systems may have larger accretion discs that emit more NIR light than the systems that we do not detect. Other scenarios such as emission from a surrounding nebula or from a compact radio jet are also possible, although for Holmberg II X-1 the NIR luminosity far exceeds the expected jet contribution. The eleven possible red supergiant counterparts are excellent candidates for spectroscopic follow-up observations. This may enable us to measure the mass function in these systems if they are indeed red supergiant donor stars where we can observe absorption lines.

description: Multiple carrier frequency offsets (CFOs) present in the uplink of orthogonal frequency division multiple access (OFDMA) systems adversely affect subcarrier orthogonality and impose a serious performance loss. In this paper, we propose the application of time domain receiver windowing to concentrate the leakage caused by CFOs to a few adjacent subcarriers with almost no additional computational complexity. This allows us to approximate the interference matrix with a quasi-banded matrix by neglecting small elements outside a certain band which enables robust and computationally efficient signal detection. The proposed CFO compensation technique is applicable to all types of subcarrier assignment techniques. Simulation results show that the quasi-banded approximation of the interference matrix is accurate enough to provide almost the same bit error rate performance as that of the optimal solution. The excellent performance of our proposed method is also proven through running an experiment using our FPGA-based system setup.

We propose simple approximating formulas for the current density distributions and critical currents.

Connecting the COVID-19 dots: susceptibility factors and host response immunodynamics in SARS-CoV-2 infection and disease severity
Creators: name: Rupsha Fraser
Publisher: name: Zenodo
Year: 2020

description: The human severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the COVID-19 (coronavirus disease 2019) pandemic, has a vast heterogeneity of host responses, with resulting symptoms ranging from an asymptomatic phenotype, to a mild−moderate disease course, to a severe or critical disease status with significant hypoxia accompanied by acute respiratory distress syndrome, extensive pulmonary damage, and circulatory and multiorgan failure. SARS-CoV-2 infection is associated with several susceptibility factors that can contribute to a more severe clinical disease course with increased morbidity and mortality.These include age-related susceptibility (most prominent in the elderly and in infants), underlying chronic diseases and/or a compromised immune system, male sex, pregnancy and the postpartum period, specific ABO blood groups, several respiratory conditions, as well as high occupational viral exposure. However, a severe and novel disorder, termed multisystem inflammatory syndrome in children (MIS-C) and adults (MIS-A), can develop following SARS-CoV-2 infection in previously healthy individuals, which can rapidly progress to critical illness with hyperinflammatory processes leading to multiorgan damage. Furthermore, genetic factors may also influence susceptibility to SARS-CoV-2 infection and COVID-19 severity, the identification of which could prove useful as biomarkers to identify individuals at greater risk of severe disease or MIS-C/MIS-A development. Here, we aim to define (a) the immunodynamics of the range of host immune responses to SARS-CoV-2 infection, (b) how the various susceptibility factors mechanistically influence these immunodynamics, with converging mechanisms between the susceptible demographic groups contributing to a severe disease phenotype or MIS-C/MIS-A, and (c) and how these immunodynamics could inform the development of long-term immunotherapeutic strategies.

description: The dust formation process in the winds of Asymptotic Giant Branch stars is discussed, based on full evolutionary models of stars with mass in the range $1$M$_{\odot} \leq$M$\leq 8$M$_{\odot}$, and metallicities $0.001 < Z <0.008$. Dust grains are assumed to form in an isotropically expanding wind, by growth of pre--existing seed nuclei. Convection, for what concerns the treatment of convective borders and the efficiency of the schematization adopted, turns out to be the physical ingredient used to calculate the evolutionary sequences with the highest impact on the results obtained. Low--mass stars with M$\leq 3$M$_{\odot}$ produce carbon type dust with also traces of silicon carbide. The mass of solid carbon formed, fairly independently of metallicity, ranges from a few $10^{-4}$M$_{\odot}$, for stars of initial mass $1-1.5$M$_{\odot}$, to $\sim 10^{-2}$M$_{\odot}$ for M$\sim 2-2.5$M$_{\odot}$; the size of dust particles is in the range $0.1 μ$m$\leq a_C \leq 0.2μ$m. On the contrary, the production of silicon carbide (SiC) depends on metallicity. For $10^{-3} \leq Z \leq 8\times 10^{-3}$ the size of SiC grains varies in the range $0.05 μ{\rm m} < {\rm a_{SiC}} < 0.1 μ$m, while the mass of SiC formed is $10^{-5}{\rm M}_{\odot} < {\rm M_{SiC}} < 10^{-3}{\rm M}_{\odot}$. Models of higher mass experience Hot Bottom Burning, which prevents the formation of carbon stars, and favours the formation of silicates and corundum. In this case the results scale with metallicity, owing to the larger silicon and aluminium contained in higher--Z models. At Z=$8\times 10^{-3}$ we find that the most massive stars produce dust masses $m_d \sim 0.01$M$_{\odot}$, whereas models of smaller mass produce a dust mass ten times smaller. The main component of dust are silicates, although corundum is also formed, in not negligible quantities ($\sim 10-20\%$).

description: A profile of Giovanni Vidari

Giovanni Vidari (1871-1934) was an Italian philosopher and pedagogist, who studied in the University of Pavia under the guidance of Carlo Cantoni and Luigi Credaro. His formation was influenced by neokantism, on which he grafted pedagogical and psychological interests; he was critical of positivism, while sharing the importance it has given to experience. After teaching in secondary school he was called to the University of Pavia, then of Turin, where he taught Moral Philosophy and later Pedagogy. He was also rector of the Turin university in the years of the first world war, in which he took an active part in patriotic mobilization and worked with the interventionist and war relief associations. Despite having begun his political activity as mayor in radical socialist councils, from about 1910 Vidari had moved toward nationalism, whose roots were in the Risorgimento patriotism, because he believed that socialism favored the disintegration of the country. After war, his relationship with fascism was difficult: he accepted it as a solution to politic and social conflicts, but criticized the Gentile reform of school and some liberticidal measures.

Marginalized by the Turinese exponents of fascism for having signed, in 1925, the manifesto of anti-fascist intellectuals, he took refuge in studies and teaching.  In the following years he attempted however a rapprochement with the fascist regime, in the name of presumed common values, such as the Ideal, the Homeland, Humanity, making a path common to many intellectuals of his generation.

While 66.67%t of the traders saie less thari 100 crates per week, the major eggs quality , ptefeiTed by consumers is size (80.00% ). Furthermore, the result depicts that, the average totai tost1 average total return and average net income per respondent per week were W51, 621.17, W57, 459.00 and W5, 837.80 respectively. More over, the net return pe1· naira invested was found to be W0.20. Lastly, the study reveals that the major constraints to sm·ali~ scale eggs retailing in the area were eggs breakages and storage related prnblelii.s (100.00% each). Though the enterprise is profitable, there is need to safeguard and protect eggs during storages and while on transits.

description: Using a combination of different herbal substances, polyherbal anti-acne facewash gels are specially madecleansing solutions that successfully attack acne while preserving the natural balance of the skin. Thesegels are intended to rid the skin of pollutants, extra oil, and germs that cause acne, offering a mild yetefficient remedy for people who frequently break out.Common ingredients in these facewash gels include neem, which has antibacterial properties, and aloevera, which soothes and hydrates the skin. Other common herbs include tea tree oil, which is wellrecognized for its capacity to reduce inflammation and heal acne, and turmeric, which has antioxidantqualities and brightens the skin.A multifaceted treatment to acne is made possible by the polyherbal method, which addresses both theunderlying causes and the symptoms. These facewash gels might offer a more thorough treatment thansingle-ingredient treatments since they combine the benefits of multiple herbs. They are also appropriatefor daily use because most skin types tolerate them well.In conclusion, polyherbal anti-acne facewash gels, which combine the power of several herbs to supporthealthier and clearer skin, provide a natural and efficient substitute for cleaning the skin and preventing.

description: The University of Turin embossed emblem even now in use had been rediscovered in 1925. Its origin dates back to 1615 in a wax seal kept in the State Archive of Turin. Since then it has been drawn in different style on official records, diplomas, stamps and academic bulletins. By means of pictures the paper illustrates the history of this emblem from 17th century to 20th century and the symbolic elements which are figured on it (an eagle looking at the sun, a bull, three books and three small marks on each of them). The authors show a new philological interpretation of the Turin University seal which is based not only on the previously mentioned records, but also on the thin, small silver plate emblem recently acquired by the University Historical Archive and on the results of chemical and micromorphological analysis of this find.

description: We present the results of a new and improved study of the morphological and spectral evolution of massive galaxies over the redshift range 110^11 Msolar from the CANDELS WFC3/IR imaging within the COSMOS and UKIDSS UDS survey fields. We find that, by modelling the H(160) image of each galaxy with a combination of a de Vaucouleurs bulge (Sersic index n=4) and an exponential disk (n=1), we can then lock all derived morphological parameters for the bulge and disk components, and successfully reproduce the shorter-wavelength J(125), i(814), v(606) HST images simply by floating the magnitudes of the two components. This then yields sub-divided 4-band HST photometry for the bulge and disk components which, with no additional priors, is well described by spectrophotometric models of galaxy evolution. Armed with this information we are able to properly determine the masses and star-formation rates for the bulge and disk components, and find that: i) from z=3 to z=1 the galaxies move from disk-dominated to increasingly bulge-dominated, but very few galaxies are pure bulges/ellipticals by z=1; ii) while most passive galaxies are bulge-dominated, and most star-forming galaxies disk-dominated, 18+/-5% of passive galaxies are disk-dominated, and 11+/-3% of star-forming galaxies are bulge-dominated, a result which needs to be explained by any model purporting to connect star-formation quenching with morphological transformations; iii) there exists a small but significant population of pure passive disks, which are generally flatter than their star-forming counterparts (whose axial ratio distribution peaks at b/a~0.7); iv) flatter/larger disks re-emerge at the highest star-formation rates, consistent with recent studies of sub-mm galaxies, and with the concept of a maximum surface-density for star-formation activity.

description: This study was designed to examine the extent to which farmers have benefited from loans/credit activities of commercial banks in.Anambra Agricultural Zone of Anambra State, as well as analysing the factors affecting accessibility of credit/loans. To do that, two sets of questionnaires were designed and administered to 64 small-scale farmers and six officials of_ the two banks in the Anambra Agricultural Zone of the state, to -gather information and relevant data for study. The small-scale farmers and bank officials were also interviewed to licit more information on the claims and counter_x0002_claims on both sides. Simple descriptive tools and econometrics method were used to analyze the data collected and to examine the impact of certain socio~economic and other variables on loan/credit received. Access to bank loans in the area was found to depend largely on ability of the applicant to provide collateral security. Age, marital status, crop type, · and income are also found to be important and significant determinants.of access to agricultural loan in the Zone.

description: The socioeconomic analysis of marketing of yam in Enugu Urban ofEnugu State was dof!e as 120 r~spondents were used for the analysis {roni some selected markets in· the study-area.:From _the result of the analysis it was shown that more female participate in. the marketing of-yam than male. The study too indicates that those who are involved in. yam marketing in Enugu urban, Enugu State are more of younger respondents between· the ages of 40's and 50's. From the analysis one is forced to believe that younger generation are more interested in the marketing of yams in Enugu urban of Enugu state. This younger gen~ration more involvementin yam marketing is expected because fewer . "white collar'' jobs that are available in Enugu urban of Enugu state can not service the whole population· within the study area. Furthermote there is -little or no industry existing in Enugu urban where these young- men/women ,can be gainfully employed. The study reveals that many constrain [lack of ·collaterals, poor storage-facilities, poor . road networks] impede the marketing of yam in the study area and these results to low tum over from these marketers. As there are so inany channels of marketing-of yam in the study area, this makes the cost of yam to be higher then it suppose to be as shown by the tesearch done. Marketers make more money from yam due to the position of the study as a public service area where many individuals living in this area have little time to engage in commercial farming of yam. Added to this is no ease access to land in the study area.

description: Ultra Steep Spectrum (USS) radio sources are one of the efficient tracers of powerful High-z Radio Galaxies (HzRGs). In contrast to searches for powerful HzRGs from radio surveys of moderate depths, fainter USS samples derived from deeper radio surveys can be useful in finding HzRGs at even higher redshifts and in unveiling a population of obscured weaker radio-loud AGN at moderate redshifts. Using our 325 MHz GMRT observations (5-sigma ~ 800 microJy) and 1.4 GHz VLA observations (5-sigma ~ 80 - 100 microJy) available in two subfields (viz., VLA-VIMOS VLT Deep Survey (VLA-VVDS) and Subaru X-ray Deep Field (SXDF)) of the XMM-LSS field, we derive a large sample of 160 faint USS radio sources and characterize their nature. The optical, IR counterparts of our USS sample sources are searched using existing deep surveys, at respective wavelengths. We attempt to unveil the nature of our faint USS sources using diagnostic techniques based on mid-IR colors, flux ratios of radio to mid-IR, and radio luminosities. Redshift estimates are available for 86/116 (~ 74%) USS sources in the VLA-VVDS field and for 39/44 (~ 87%) USS sources in the SXDF fields with median values (z_median) ~ 1.18 and ~ 1.57, which are higher than that for non-USS radio sources (z_median non-USS ~ 0.99 and ~ 0.96), in the two subfields, respectively. The flux ratio of radio to mid-IR (S_1.4 GHz/S_3.6 micron) versus redshift diagnostic plot suggests that more than half of our USS sample sources distributed over z ~ 0.5 to 3.8 are likely to be hosted in obscured environments. A significant fraction (~ 26% in the VLA-VVDS and ~ 13% in the SXDF) of our USS sources without redshift estimates mostly remain unidentified in the existing optical, IR surveys, and exhibit high radio to mid-IR flux ratio limits similar to HzRGs, and thus, can be considered as potential HzRG candidates.

description: Recent studies have shown the classification and prediction power of the Neural Networks. It has been demonstrated that a NN can approximate any continuous function. Neural networks have been successfully used for forecasting of financial data series. The classical methods used for time series prediction like Box-Jenkins or ARIMA assumes that there is a linear relationship between inputs and outputs. Neural Networks have the advantage that can approximate nonlinear functions. In this paper we compared the performances of different feed forward and recurrent neural networks and training algorithms for predicting the exchange rate EUR/RON and USD/RON. We used data series with daily exchange rates starting from 2005 until 2013.
