description: Individual sports competitions provide a natural setting for examining the relative importance of talent and luck/chance in achieving success. The belief that success is primarily due to individual abilities and hard work rather than external factors is particularly strong in this context. In this study, we test this belief using tennis as a case study, due to its popularity and competition structure in direct-elimination tournaments. Our dataset covers the decade 2010-2019 of main events in the ATP circuit and consists of tourney results and annual rankings for professional male players. After a preliminary data analysis, we introduce an agent-based model able to accurately simulate the tennis players' dynamics along several seasons. We show that, once calibrated on the dataset, the model is able to reproduce the main stylized facts observed in real data, including the results of single tournaments and the development of players' careers in the ATP community. The strength of our approach lies in its simplicity: it requires only one free parameter a to determine the importance of talent in scoring every single point: a = 1, if only talent matters; a = 0, if the outcome of each point is entirely due to chance. We find the best agreement between real data and simulation results when talent weights substantially less than luck, i.e. when a is between 0.20 and 0.30. A further comparison between data and simulations, based on the analysis of the direct networks of all the matches, confirms the previous finding. A posteriori, we notice that this surprisingly important role of chance in tennis tournaments is not an exception. On the contrary, it can be explained by a more general paradoxical effect that characterizes highly competitive environments, particularly in individual sports. In other words, when the difference in talent between top players is minimal, chance becomes determinant.

description: We provide all basic equations and concepts required to carry out a general study on axially symmetric static sources. The Einstein equations and the conservation equations are written down for a general anisotropic static fluid endowed with axial symmetry. The structure scalars are calculated and the inhomogeneity factors are identified. Finally some exact analytical solutions were found. One of these solutions describes an incompressible spheroid with isotropic pressure and becomes the well known interior Schwarzschild solution in the spherically symmetric limit, however it cannot be matched smoothly to any Weyl exterior metric. Another family of solutions was found that corresponds to an anisotropic fluid distribution and can in principle be matched to a Weyl exterior.

description: Bovine tuberculosis, caused by Mycobacterium bovis, which belongs to Mycobacterium tuberculosis complex (MTC), is a globally distributed zoonotic disease in cattle and remained an economic problem in Ethiopia. This study was conducted from November 2015 to May 2017 on 502 dairy cattle managed under the Dairy Farm at Holeta Agricultural Research Center. The objectives of the study were to estimate the prevalence, evaluate gamma interferon and comparative intradermal tuberculin test (CIDTT) for the diagnosis of bovine tuberculosis, and isolate, identify, and characterize causative agents of bovine tuberculosis using RD4 deletion typing molecular technique. Data collected on study animals were analyzed using STATA version13 software. Out of 502 cattle examined using different methods, 148 (29.5%, 95% CI: 25.5 - 33.7%) were positive for bovine tuberculosis using CIDTT, 173 (34.5%, 95% CI: 30.3 -38.8%) for Gamma-Interferon and 97 (19.3%, 95% CI: 15.9 – 23.1%) were positive for both tests. The results indicated moderate Kappa agreement between the two tests. Among 60 slaughtered animals that were positive for both test, 48 (80.0%) had gross tuberculosis lesion while the rest 12 (20.0%) had no such lesions. Out of 48 gross lesions cultured on Löwenstein–Jensen medium, 24 samples were culture-positive (19 on pyruvate enriched media that were suspected as Mycobacterium bovis while the 5 on glycerol which suspected as Mycobacterium tuberculosis). All of the isolates were subjected to PCR amplification for RD4 deletion typing technique that confirmed 8 (33.3%) of the isolates to be M. bovis. The rest being other members of the genus Mycobacterium. From the study it was concluded that bovine tuberculosis is highly prevalent in the studied farm. The comparison of evaluation techniques indicated the presence of moderate Kappa agreement between gamma interferon (ELISA) and tuberculin test (PPD). Therefore, it is recommended that an urgent need for regular surveillance, implementation of strict biosecurity measures and further large scale molecular epidemiological studies need to be implemented for effective prevention and control of bovine tuberculosis.

description: Apart from some strongly fluorescent wood species, the general fluorescence of wood has long been ignored. Recent studies suggest that each species has a distinct fluorescence, originating from both basic components and characteristic extractives. However, wood colour and fluorescence rapidly change upon exposure to sunlight. In this study, 288 samples of Acer pseudoplatanus, Quercus robur, Picea abies and Juglans nigra were irradiated with different bands of ultraviolet (UV) and visible (VIS) light. Photosensitivity was examined in regards of colour, infrared absorbance (FTIR), and fluorescence imaging. UV light caused strong yellowing in all examined species, mostly correlating with lignin degradation, carbonyl formation and the appearance of a broad banded fluorescence emission. VIS light above 420 nm, however, caused different, partly contradicting effects in colour and fluorescence, and did not affect lignin. Juglans nigra proved to be most sensitive towards VIS- induced yellowing and bleaching. The main new finding of this study is that the native long wave fluorescence of wood was strongly decreased by VIS-irradiation above 510 nm wavelength in all samples. This effect was not species-specific, probably originating from a cross-species wood component. The results have potential impacts on non-destructive image-based evaluation methods and wood identification.

description: Schmidt, Jones, and Kennedy's (SJK) (2023, https://doi.org/10.1029/2022GL102530) critique of Scafetta (2022, https://doi.org/10.1029/2022GL097716) is flawed. Their assessment of the error of the ERA-T2m 2011-2021 mean (about 0.10 °C) is 5-10 times overestimated and contradicts published literature. SJK confused natural variability with random noise and mistook the error of the mean of a temperature chronology for the stochastic error of the regression parameter M of a nonphysical isothermal climate model (T(t) = M). SJK's allegations regarding the internal variability of the models, the role of the global climate model ensemble members, and other issues were partially addressed in Scafetta (2022, https://doi.org/10.1029/2022GL097716) and, later, more extensively in Scafetta (2023a, https://doi.org/10.1007/s00382-022-06493-w) where Scafetta's (2022, https://doi.org/10.1029/2022GL097716) conclusions were confirmed.

description: Seagrasses are essential marine ecosystems for which restoration has proven challenging due to increased hydrodynamic stress. This study aims to analyze the flow alteration induced by an artificial seagrass (ASG) meadow by characterizing its wake effect through a shelter distance and thus yield guidance for seagrass restoration projects. Here, we define shelter distance as the longitudinal extent behind a meadow, with respect to the flow direction, where seagrass is protected and can hence grow successfully. Flume experiments were conducted for submerged meadows with three different lengths at constant canopy height, shoot density and water depth, and three different cross-section-averaged longitudinal flow velocities measured with state-of-the-art Particle Image Velocimetry (PIV). For the tested meadow morphology and hydrodynamic conditions, meadow length played a less important role regarding shelter distance, while incident flow velocity and effective canopy height governed the wake effect. Incident velocities <30 cm s−1 prompted shelter distances >2 m behind the meadow, whereas higher velocities led to a reduced shelter distance ranging from 20-40 cm. ASG additionally produced an upwelling effect on the vertical distribution of the velocity profile observed along the wake, regardless of meadow length and incident velocity. Our results suggest that restoration projects should aim for areas of low flow, where currents induced by tidal or wind waves are less pronounced in order to activate larger shelter distances.

description: We develop a partial Hamiltonian framework to obtain reductions and closed-form solutions via first integrals of current value Hamiltonian systems of ordinary differential equations (ODEs). The approach is algorithmic and applies to many state and costate variables of the current value Hamiltonian. However, we apply the method to models with one control, one state and one costate variable to illustrate its effectiveness. The current value Hamiltonian systems arise in economic growth theory and other economic models. We explain our approach with the help of a simple illustrative example and then apply it to two widely used economic growth models: the Ramsey model with a constant relative risk aversion (CRRA) utility function and Cobb Douglas technology and a one-sector AK model of endogenous growth are considered. We show that our newly developed systematic approach can be used to deduce results given in the literature and also to find new solutions.

description: Intracochlear optical stimulation has been suggested as an alternative approach to hearing prosthetics in recent years. This study investigated the properties of a near infrared laser (NIR) induced optoacoustic effect. Pressure recordings were performed at the external meatus of anaesthetized guinea pigs during intracochlear NIR stimulation. The sound pressure and power spectra were determined. The results were compared to multi unit responses in the inferior colliculus (IC). Additionally, the responses to NIR stimulation were compared to IC responses induced by intracochlear electric stimulation at the same cochlear position to investigate a potentially confounding contribution of direct neural NIR stimulation. The power spectra of the sound recorded at the external meatus (n = 7) had most power at frequencies below 10 kHz and showed little variation for different stimulation sites. The mean spike rates of IC units responding to intracochlear NIR stimulation (n = 222) of 17 animals were significantly correlated with the power of the externally recorded signal at frequencies corresponding to the best frequencies of the IC units. The response strength as well as the sound pressure at the external meatus depended on the pulse peak power of the optical stimulus. The sound pressure recorded at the external meatus reached levels above 70 dB SPL peak equivalent. In hearing animals a cochlear activation apical to the location of the fiber was found. The absence of any NIR responses after pharmacologically deafening and the comparison to electric stimulation at the NIR stimulation site revealed no indication of a confounding direct neural NIR stimulation. Intracochlear optoacoustic stimulation might become useful in combined electro-acoustic stimulation devices in the future.

description: In this paper, we present for the first time comprehensive and detailed results on the correspondence between the extrapolated deep inelastic structure function $g_1$ of both the proton and the neutron with the same quantity measured in the nucleon resonance region. We use a QCD parameterization of the world data on DIS spin structure functions, extrapolated into the nucleon resonance region and averaged over various intervals in the scaling variable $x$. We compare the results with the large data set collected in the quark-hadron transition region by the CLAS collaboration, averaged over the same intervals. We present this comparison as a function of the momentum transfer $Q^2$. We find that, depending on the averaging interval and the minimum momentum transfer chosen, a clear transition to quark-hadron duality can be observed in both nucleon species. Furthermore, we show, for the first time, the scaling behavior of $g_1$ measured in the resonance region at sufficiently high momentum transfer. Our results can be used to quantify the deviations from the applicability of pQCD for data taken at moderate energies, and help with extraction of quark distribution functions from such data.

description: Usually, solar heat in combi systems is used via a buffer storage. In contrast to that, the solar collectors may be connected directly to the space heating circuit in order to store the heat in the building itself. Such a direct solar integration is investigated within system simulations for different layouts and heating elements. The simulations show significant reductions in the final energy demand as well as an increasing solar yield due to less thermal losses of the storage tank compared to the usual solution with one buffer storage. A prototype of one of the investigated heating concepts within a single family house proofs the functionality of the system concept and the high solar yield, particularly at low radiation levels. Since only a few manufacturers provide such system solutions with a direct solar integration, the results may have an important impact on the future development of combi systems.

description: A cross sectional study was conducted from November 2017 to April 2018 to estimate the prevalence of gastrointestinal parasites of chicken managed in different production systems in selected areas of east Hararghe, Ethiopia. A total of 324 local and 126 exotic breeds of chicken were used in the study. Chickens in the farm and village were followed until drop feces and fecal samples were carefully collected from the top of freshly dropped feces excluding soil contamination for parasitological examination. Flotation and McMaster counting techniques were used for qualitative and quantitative evaluation of fecal samples, respectively. Out of the 450 chickens’ feces examined, 27.1% and 49.5% were positive for Eimeria oocysts and nematode eggs, respectively. High prevalence (P<0.05) of coccidian infection was observed in exotic breed (48.4%) chickens as compared to the free-range local chickens (18.8%), while high prevalence (P<0.05, COR, 0.4) of nematode infection was observed in local (57.1%) than exotic (0%) chicken breeds. Nearly equal rate of prevalence was recorded in different sex groups for coccidia (male 27.4%, female 27%) and nematodes (male 41.7%, female, 40.8%). A higher nematodes prevalence was recorded in extensive (62.6%) than intensive (13.3%) and semi-intensive (12.9%) management systems (P<0.05). Eimeria infection was greater for intensive (31.7%) and semi-intensive (28.6%) than extensive (24.4%), management systems. Majority of the chickens harbored light degree of coccidia infection. Ascaridia galli (37.1%) was the dominant nematode followed by Heterakis gallinarum (10.4%) and Dispharnx (2%). In conclusion, Eimeria and gastrointestinal nematodes were important parasites in the study area. It was recommended that awareness should be created on the importance, prevention, and control of coccidiosis and gastrointestinal nematodes for exotic chicken producers and for chicken managed under extensive system, respectively.

description: Prediction of stock prices plays a significant role in aiding the decision-making of investors. Considering its importance, a growing literature has emerged trying to forecast stock prices with improved accuracy. In this study, we introduce an innovative approach for forecasting stock prices with greater accuracy. We incorporate external economic environment-related information along with stock prices. In our novel approach, we improve the performance of stock price prediction by taking into account variations due to future expected macroeconomic policy changes as investors adjust their current behavior ahead of time based on expected future macroeconomic policy changes. Furthermore, we incorporate macroeconomic variables along with historical stock prices to make predictions. Results from this strongly support the inclusion of future economic policy changes along with current macroeconomic information. We confirm the supremacy of our method over the conventional approach using several tree-based machine-learning algorithms. Results are strongly conclusive across various machine learning models. Our preferred model outperforms the conventional approach with an RMSE value of 1.61 compared to an RMSE value of 1.75 from the conventional approach.

description: We show the analysis of a thin accretion disk around a static and spherically symmetric black hole in dRGT massive gravity. We present the accretion disk analysis in a gravitational theory with a nonzero graviton mass. Also, we study the event horizons of the black hole and we calculate the equations of motion and effective potential. In the following, we obtain the specific energy, specific angular momentum, and angular velocity of the particles which move in circular orbits. In addition, we plot the effective potentials for two cases and we show the locations of stable circular orbits. At last, we show the possibility of constraining the parameter space of dRGT massive gravity by the astrophysical gamma-ray bursts.

description: The polycrystalline co-doped samples of Sm0.5Y0.5Fe0.58Mn0.42O3 were prepared by solid-state reaction route and its various physical properties with their correlations have been investigated. The dc magnetization measurements on the sample revealed a weak ferromagnetic (WFM) transition at TN=361 K that is followed by an incomplete spin reorientation (SR) transition at TSR1= 348 K. A first order magnetic transition (FOMT) around 292 K completes the spin reorientation transition and the material enters into a nearly collinear antiferromagnetic (AFM) state for T < 260 K. The compound exhibited magnetization reversal below the compensation temperature (Tcomp) = 92 K at low measured field of 100 Oe. At further low temperature below 71 K, the compound also exhibited Zero-field cooled memory effects confirming a reentrant spinglass state formation. Robust magnetodielectric (MD) magnetoelectric coupling has been established in the present material through field dependent dielectric and resistivity measurements. True ferroelectric transition with a considerable value of saturation polarization (= 0.06 micro C/cm2 at 15 K) have been found in the specimen below TFE= 108 K. We observed an intense spin-phonon coupling (SPC) across TSR and TN from the temperature dependent Raman spectroscopy and is responsible for the intrinsic magnetoelectric effect. This SPC also stabilizes the ferroelectric state below TFE in the material. The delicate interplay of the lattice (Phonons), charge and spins governs the observed features in the investigated physical properties of the material that makes the specimen a promising multifunctional material.

description: The resilience of cities has become an important topic to be considered by authorities in planning (MYRIVILI 2017, oral). Nowadays, many cities need to face various problems caused by environment, such as earthquakes, heat islands or floods (ibid.). The case study takes place in the centre of the city of Athens, to which the main emphasis has been paid during the research. This place also has to fight the shock of heat waves that occur during summer seasons on a daily basis (ibid.). It is not only a challenge for planning authorities, but most importantly it affects people who live in such areas. Therefore, the heat waves have significant impact on Athens’ neighbourhoods, as its occurrence makes those areas barely liveable for people (PAPAIOANNOU 2017, oral). It is mainly burdensome for the inhabitants of such district, where the surrounding areas have not been improved in ages, have not followed the newest and more socially friendly standards, which could reduce heat islands and therefore provide inhabitants with more liveable places to live in, like the researched one (ibid.). The proposal of transforming the heat islands to neat islands in the central district of Athens focuses on the creation of new green and clean places, where people could gather together, but at the same time, these areas would be efficiently reducing the phenomenon of heat islands.

description: We present angle-uniform parallel coordinates, a data-independent technique that deforms the image plane of parallel coordinates so that the angles of linear relationships between two variables are linearly mapped along the horizontal axis of the parallel coordinates plot. Despite being a common method for visualizing multidimensional data, parallel coordinates are ineffective for revealing positive correlations since the associated parallel coordinates points of such structures may be located at infinity in the image plane and the asymmetric encoding of negative and positive correlations may lead to unreliable estimations. To address this issue, we introduce a transformation that bounds all points horizontally using an angle-uniform mapping and shrinks them vertically in a structure-preserving fashion; polygonal lines become smooth curves and a symmetric representation of data correlations is achieved. We further propose a combined subsampling and density visualization approach to reduce visual clutter caused by overdrawing. Our method enables accurate visual pattern interpretation of data correlations, and its data-independent nature makes it applicable to all multidimensional datasets. The usefulness of our method is demonstrated using examples of synthetic and real-world datasets.

description: The Human Activity Recognition (HAR) tasks automatically identify human activities using the sensor data, which has numerous applications in healthcare, sports, security, and human-computer interaction. Despite significant advances in HAR, critical challenges still exist. Game theory has emerged as a promising solution to address these challenges in machine learning problems including HAR. However, there is a lack of research work on applying game theory solutions to the HAR problems. This review paper explores the potential of game theory as a solution for HAR tasks, and bridges the gap between game theory and HAR research work by suggesting novel game-theoretic approaches for HAR problems. The contributions of this work include exploring how game theory can improve the accuracy and robustness of HAR models, investigating how game-theoretic concepts can optimize recognition algorithms, and discussing the game-theoretic approaches against the existing HAR methods. The objective is to provide insights into the potential of game theory as a solution for sensor-based HAR, and contribute to develop a more accurate and efficient recognition system in the future research directions.

description: Probabilistic quantum error correction is an error-correcting procedure which uses postselection to determine if the encoded information was successfully restored. In this work, we deeply analyze probabilistic version of the error-correcting procedure for general noise. We generalized the Knill-Laflamme conditions for probabilistically correctable errors. We show that for some noise channels, we should encode the information into a mixed state to maximize the probability of successful error correction. Finally, we investigate an advantage of the probabilistic error-correcting procedure over the deterministic one. Reducing the probability of successful error correction allows for correcting errors generated by a broader class of noise channels. Significantly, if the errors are caused by a unitary interaction with an auxiliary qubit system, we can probabilistically restore a qubit state by using only one additional physical qubit.

description: A study was conducted to investigate the in-vitro and in vivo anthelmintic effects of crude methanol extracts of Azadirachta indica, Vernonia amygdalina, Nicotiana tabacum, Moringa oleifera, Croton macrostachyus, and Hagenia abyssinica against gastrointestinal nematodes of goats. The plants were collected from East Hararghe Zone during November 2017 to March 2018. Leaves from each plant species were separately collected, dried, ground, and crude methanol soluble was extracted. Three graded concentration of crude extract of 100mg/ml, 50mg/ml and 25mg/ml were prepared and evaluated for in vitro anthelmintic effects using standard techniques of larval development assay, larvae inhibition and egg hatch tests. For the egg hatch test, the wells containing about 100 eggs/ml were incubated at 27°C for 48 hours and evaluated based on the characteristics such as dead, embryonated, or hatched egg to L1. Similar egg concentrations were used for larval development assays and exposed to various concentrations of the plant extracts to evaluate the development of eggs to infective larvae (L3) over a period of six to seven days. For the larvae inhibition test, approximately 100 larvae were placed into test tubes containing plant extracts. The results were evaluated by adding a drop of warm water and counting of active and dead larvae at an interval of three hours, for a total period of twelve hours. For the in vivo trial, 1g/kg of the crude extract of the plants were prepared and administered via oral drenching. High (p<0.05) percentage of in vitro egg hatchability inhibition was recorded for Croton macrostachyus as compared to the other plant species while the lowest inhibition was recorded for Moringa oleifera and Hagenia abyssinica. Nicotiana tabacum caused 100% larval (L3) mortality within three hours at 100mg/ml and 50mg/ml while the other plants extract did not show substantial effect. The development of larvae from L1 to L3 was arrested following exposure to extracts of Nicotiana tabacum, Vernonia amygdalina, and Croton macrostachyus. In vivo test result showed 96.6% fecal egg count reduction in crude extract of Nicotiana tabacum drenching, which was better (p<0.05) than the other plants tested and the positive control. In general, the in vitro and in vivo results show that crude extracts of Nicotiana tabacum, Vernonia amygdalina, and Croton macrostachyus were promising for the control of gastrointestinal nematodes. Thus, further studies are required to evaluate toxicity, dose and active ingredients/chemicals determination of crude extracts of these plants for possible production of alternative natural anthelmintic.

description: Le ksar représente l’un des éléments architecturaux les plus remarquables des paysages rural de l’ensemble des oasis du Sud-ouest algérien. Le ksar, par sa forme et son style architectural esthétique produit une grande séduction aussi bien sur le simple touriste que sur l’anthropologue, l’historien ou le géographe arpentant les espaces solitaires à la porte de l’immensité désertique, le sociologue qui scrute une société pétrie par l’eau et le sable ou l’architecte perplexe devant l’harmonie d’un habitat ocre sorti de la terre. Ces ksour soufrent du problème d’ensablement à cause de la nature saharienne. On propose dans ce travail une étude de l’effet des grains de silicium apporté par le vent sable sur l’adobe utilisé dans la construction des Ksour en faisant une modélisation par le code ABAQUS. On a fourni les caractéristiques physico-chimiques du silicium et de l’adobe et à l’aide du code ABAQUS on pourrait poursuivre le comportement de chaqu’un des deux matériaux où on a fixé trois vitesse différentes du vent de sable afin de poursuivre le déplacement, la contrainte de von mises et la contrainte plastique équivalente.

description: Background: Noninvasive electrical stimulation (ES) could have therapeutic potential in stroke recovery. However, there is no comprehensive evaluation of adverse events. This study systematically searched the literature to document frequency and prevalence of adverse events. A secondary aim was to explore associations between adverse events and ES parameters or participant characteristics. Methods: Databases were searched for studies evaluating ES in adults with stroke. All included studies were required to report on adverse events. Extracted data were: (1) study design; (2) adverse events; (3) participant characteristics; (4) ES parameters. Results: Seventy-five studies were included. Adverse events were minor in nature. The most frequently reported adverse events were tingling (37.3% of papers), burning (18.7%), headaches (14.7%) and fatigue (14.7%). Cathodal stimulation was associated with greater frequency of itching (p = .02), intensities of 1–2 mA with increased tingling (p = .04) and discomfort (p = .03), and current density <0.4mA/cm2 with greater discomfort (p = .03). Tingling was the most prevalent adverse event (18.1% of participants), with prevalence data not differing between active and control conditions (all p ≥ 0.37). Individual participants were more likely to report adverse events with increasing current density (r = 0.99, p = .001). Two severe adverse events were noted (a seizure and percutaneous endoscopic gastrostomy placement). Conclusion: ES appears safe in people with stroke as reported adverse events were predominantly minor in nature. An adverse events questionnaire is proposed to enable a more comprehensive and nuanced analysis of the frequency and prevalence of adverse events.
