description: The recent observation of the shadow of the supermassive black hole M87*, located at the centre of the M87 galaxy, by the Event Horizon Telescope collaboration has opened up a new window to probe the strong gravity regime. In this letter, we explicitly demonstrate the consequences of this observation on brane world black holes, characterized by existence of a negative tidal charge. Our results based on three observables associated with the shadow, namely, angular diameter, deviation from circularity and axis ratio reveal that the existence of a negative tidal charge is more favoured, possibly marking a deviation from general relativity.

description: Reactive oxygen species (ROS) play an important role as endogenous mediators in several cellular signalling pathways. However, at high concentrations they can also exert deleterious effects by reacting with many macromolecules including DNA, proteins and lipids. The precise balance between ROS production and their removal via numerous enzymatic and nonenzymatic molecules is of fundamental importance for cell survival. Accordingly, many neurodegenerative disorders, including Parkinson’s disease (PD), are associated with excessive levels of ROS, which induce oxidative damage. With the aim of coping with the progression of PD, antioxidant compounds are currently receiving increasing attention as potential co-adjuvant molecules in the treatment of these diseases, and many studies have been performed to evaluate the purported protective effects of several antioxidant molecules. In the present review, we present and discuss the relevance of the use of Drosophila melanogaster as an animal model with which to evaluate the therapeutic potential of natural and synthetic antioxidants. The conservation of most of the PD-related genes between humans and D. melanogaster, along with the animal’s rapid life cycle and the versatility of genetic tools, makes fruit flies an ideal experimental system for rapid screening of antioxidant-based treatments.

description: Automatic annotation for three-dimensional (3D) cephalometric analysis has been limited by computational complexity and computing performance. The purpose of this study was to evaluate the accuracy of our newly-developed automatic 3D cephalometric annotation system using a deep learning algorithm. Our model system mainly consisted of a 3D convolutional neural network and image data resampling. Discrepancies between the referenced and predicted coordinate values in three axes and in 3D distance were calculated to yield prediction errors of 3.26, 3.18, and 4.81 mm (for three axes) and 7.61 mm (for 3D). Moreover, there was no difference (p > 0.05) among the landmarks of three groups (midsagittal plane, horizontal plane and mandible). Although our 3D convolutional neural network-based annotation system could not achieve the level of accuracy demanded by immediate clinical applications, it can nevertheless serve as an initial approximate guide to landmarks, thus reducing the time needed for annotation.
Generalized Disclination Mechanics with Couple Stress

subject: FOS: Materials engineering

description: The objective of this work is to develop and implement a computational algorithm for calculating stress and moment-stress fields induced by line and planar defects, such as dislocations and phase/grain boundaries, represented as g.disclinations, as well as their evolution. This results in coupled plasticity and interface motion, fully coupled to stress, couple stress and applied boundary conditions. To achieve this the continuum approach for small deformations will be considered, following the formulation outlined in [AF15] extended herein in the thermodynamics to accommodate physically necessary ingredients that arose in the modeling in [ZA18, ZAP18]. Constitutive relations will be derived from kinematics, balance laws and from the use of the second law of thermodynamics in global form. Kinematicrelations will also inform the evolution of fields, among them the defect fields themselves and the plastic deformation field. One of the challenges presented by this approach is the inclusion of couple stresses [Tou64], and the consequenttreatment of 4th order systems arising from the equations of balance of linear momentum and angular momentum. In order to deal with these equations the classic FEM approach is replaced by iso-geometric analysis (IGA), as proposedby [HCB05]. The motivation to use couple stresses in the model is twofold. First, based on [Her51, Mul56] and subsequent work, there is a widely used and successful framework for grain-boundary evolution based on misorientation dependent energy density without any consideration of stresses or elastic deformation. This approach indicates that grain boundary evolution is dependent not on stresses on the boundary, but on the couples/torques acting on it. Second, motivated by the analysis of shear-coupled grain boundary migration performed by [TCH+17] and the work done by [TCF14], the inclusion of couple stresses have been shown to model theexperimentally observed phenomenon of shear-coupled grain boundary migration attributable to disclination defects. Complementary to these couple-stress driven approaches to interface migration, it is shown in this thesis that the new thermodynamic dependencies allow for the evolution of eigenwall-modeled boundaries to migrate driven simply by applied stress, which also permits the treatment ofshear-coupled grain boundary migration. The coupling of the dislocation density with the eigenwall allows for the capturing of the shear parallel to the grain boundarythat is concomitant with the grain boundary migration, as has been observed experimentally and through molecular dynamics.

description: We consider preoperative prediction of thyroid cancer based on ultra-high-resolution whole-slide cytopathology images. Inspired by how human experts perform diagnosis, our approach first identifies and classifies diagnostic image regions containing informative thyroid cells, which only comprise a tiny fraction of the entire image. These local estimates are then aggregated into a single prediction of thyroid malignancy. Several unique characteristics of thyroid cytopathology guide our deep-learning-based approach. While our method is closely related to multiple-instance learning, it deviates from these methods by using a supervised procedure to extract diagnostically relevant regions. Moreover, we propose to simultaneously predict thyroid malignancy, as well as a diagnostic score assigned by a human expert, which further allows us to devise an improved training strategy. Experimental results show that the proposed algorithm achieves performance comparable to human experts, and demonstrate the potential of using the algorithm for screening and as an assistive tool for the improved diagnosis of indeterminate cases.

description: In this study, pure polyaniline (PANI0) and polyaniline/titanium dioxide composites, including 15 wt.% TiO2 (PANI15) and 25 wt.% TiO2 (PANI25), respectively, were synthesised using an in-situ polymerisation technique in the absence and in the presence of titanium dioxide nanoparticles, respectively. The solid-phase photocatalytic degradation of polyaniline/titanium dioxide (TiO2) composites was compared with that of the pure polyaniline with the aid of weight loss measurements. The structural and morphological properties of the prepared samples were studied by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, energy dispersive X-ray analysis, thermogravimetric analysis and X‐ray diffraction analysis. The loading of TiO2 nanoparticles in polyaniline enhanced the solid-phase photocatalytic degradation of the pure polymer both under UVA light and under UVC light, respectively. Fourier transform infrared spectroscopy illustrated that Pani was synthesised successfully in the presence of TiO2 nanoparticles. Field emission scanning electron microscopy revealed homogeneous TiO2 dispersion within Pani matrix. Thermogravimetric analysis supported the idea that the thermal property of the pure polymer was improved with the photocatalyst contribution. The crystalline structure of TiO2 did not change with Pani.

description: We assessed which intervention components were associated with change in moderate-to-vigorous physical activity (MVPA) and wellbeing through proposed psychosocial mediators. Eight schools (n = 1319; 13−14 years) ran GoActive, where older mentors and in-class-peer-leaders encouraged classes to conduct two new activities/week; students gained points and rewards for activity. We assessed exposures: participant-perceived engagement with components (post-intervention): older mentorship, peer leadership, class sessions, competition, rewards, points entered online; potential mediators (change from baseline): social support, self-efficacy, group cohesion, friendship quality, self-esteem; and outcomes (change from baseline): accelerometer-assessed MVPA (min/day), wellbeing (Warwick-Edinburgh). Mediation was assessed using linear regression models stratified by gender (adjusted for age, ethnicity, language, school, BMI z-score, baseline values), assessing associations between (1) exposures and mediators, (2) exposures and outcomes (without mediators) and (3) exposure and mediator with outcome using bootstrap resampling. No evidence was found to support the use of these components to increase physical activity. Among boys, higher perceived teacher and mentor support were associated with improved wellbeing via various mediators. Among girls, higher perceived mentor support and perception of competition and rewards were positively associated with wellbeing via self-efficacy, self-esteem and social support. If implemented well, mentorship could increase wellbeing among adolescents. Teacher support and class-based activity sessions may be important for boys’ wellbeing, whereas rewards and competition warrant consideration among girls.

description: The development of EHL theory from its tentative beginnings is outlined, with an account of how Ertel explained its relation to Hertz contact theory. The problems caused by the failure of the early numerical analysts to understand that the film thickness depends on only two variables are emphasised, and answers of the form H = F ( P , S ) given. Early methods of measuring the film thickness are described, but these became archaic with the development of optical EHL. The behaviour of surface roughness as it passes through the high pressure region and suffers elastic deformation is described, and the implication for the traditional Λ -ratio noted. In contrast, the understanding of traction is far from satisfactory. The oil in the high pressure region must become non-Newtonian: the early explanation that the viscosity reduction is the effect of temperature proved inadequate. There must be some form of shear thinning (perhaps according to the Eyring theory), but also a limiting shear stress under which the lubricant shears as an elastic solid. It seems that detailed, and difficult, measurements of the high pressure, high shear-rate behaviour of individual oils are needed before traction curves can be predicted.

description: Superconducting microwave parametric amplifiers are attractive due to their ability to reach quantum limit of noise. They have enabled ultrasensitive detection of photons in radio astronomy and real-time readout of superconducting quantum bits. In this thesis, I will present the results of modelling of two different kinds of Josephson Travelling Wave Parametric Amplifier (JTWPA) architectures. First, I give the quantum mechanical model of a basic JTWPA, achieving the same expectation values as the classical modelling. Afterwards I present a quantum model for a JTWPA element with resonant phase matching (RPM), in order to deal with non-linear effects in the dispersion relation at high pump currents. Both models are modelled within the lumped element limit.

description: Employing a novel text mining method proposed by Ke et al. (2019), I carry out a comprehensive textual analysis of Chinese company announcements for stock return prediction. The long-short portfolio based on article sentiment scores yields 78% cumulative returns with a Sharpe ratio of 0.86 from 2016 to 2019. The model well captures the contemporaneous association between announcement sentiment and stock returns. There is also evidence for the information leakage before the announcements are made public. Careful examination of the traded articles finds that they are longer than average, suggesting complex information may not be fully digested by the investors as they are released. Company annual reports and financing activities reports play important roles in explaining the portfolio's performance.

description: We observe a significant steady-state deviation from the generalized equipartition theorem, one of the pivotal results of classical statistical mechanics, in a system of confined, laser cooled atoms. We quantify this deviation, measure its dynamics and show that its steady state value quantifies the departure of non-thermal states from thermal equilibrium even for anharmonic confinement. In particular, we find that deviations from equipartition grow as the system dynamics becomes more anomalous. We present numerical simulations that validate the experimental data and reveal an inhomogeneous distribution of the kinetic energy through the system, supported by an analytical analysis of the phase space.m, supported by an analytical analysis of the phase space.

description: We study the Cosmic Microwave Background (CMB) anisotropies produced by cosine-type quintessence models. In our analysis, effects of the adiabatic and isocurvature fluctuations are both taken into account. For purely adiabatic fluctuations with scale invariant spectrum, we obtain a stringent constraint on the model parameters using the CMB data from COBE, BOOMERanG and MAXIMA. Furthermore, it is shown that isocurvature fluctuations have significant effects on the CMB angular power spectrum at low multipoles in some parameter space, which may be detectable in future satellite experiments. Such a signal may be used to test the cosine-type quintessence models.

First, we prove that if $G$ is a group of order $n$ and $ψ(G) >31ψ(C_n)/77$, where $C_n$ is the cyclic group of order $n$, then $G$ is supersolvable. This proves a conjecture of M.~{Tărnăuceanu}. Moreover, M. Herzog, P. Longobardi and M. Maj put forward the following conjecture: If $H\leq G$, then $ψ(G) \leqslant ψ(H) |G:H|^2$. In the sequel, by an example we show that this conjecture is not satisfied in general.

description: USDA generates monthly season‐average price forecasts for key agricultural commodities. Uncertainty about each forecast is indicated by its publication as a price interval. USDA’s forecasting methodology is non‐public, but its uncertainty levels are anecdotally based on historical patterns of price uncertainty and informed by expert opinion. No confidence level is attached to USDA’s intervals, so it is difficult to gauge their accuracy. But in practice, realized season‐average prices regularly fall outside of USDA‐forecasted intervals, particularly those made prior to harvest and late in the marketing year. We demonstrate that forward‐looking density forecasts for the season‐average corn price can be constructed based on the market’s expectation of volatility implied by commodity options premia, combined with historical forecast errors between futures market prices and cash prices paid to farmers. Because implied volatility is forward‐looking, confidence intervals based on these densities reflect anticipatory market sentiment not present in historical data. In out‐of‐sample trials, our 95% confidence intervals contained the final season‐average price for over 92% of the 358 forecasts made between 1995/96 and 2014/15. Compared to a model based on historical data alone, the forward‐looking model is less susceptible to forecast errors. Our approach can enhance the informational value of USDA season‐average price forecasts.
Quantum Cybernetics: A New Perspective for Nelson's Stochastic Theory, Nonlocality, and the Klein-Gordon Equation
Creators: name: Groessing, Gerhard
Publisher: name: arXiv
Year: 2002

description: The Klein-Gordon equation is shown to be equivalent to coupled partial differential equations for a sub-quantum Brownian movement of a ''particle'', which is both passively affected by, and actively affecting, a diffusion process of its generally nonlocal environment. This indicates circularly causal, or ''cybernetic'', relationships between ''particles'' and their surroundings. Moreover, in the relativistic domain, the original stochastic theory of Nelson is shown to hold as a limiting case only, i.e., for a vanishing quantum potential.

All-optical spin switching under different spin configurations

description: We employ an atomic spin model and present a systematic investigation from a single spin to a large system of over a million spins. To have an efficient spin switching, the electron initial momentum direction must closely follow the spin's orientation, so the orbital angular momentum is transverse to the spin and consequently the spin-orbit torque lies in the same direction as the spin. The module of the spin-orbit torque is $λ|{\bf S}||{\bf r}||{\bf P}| \sqrt{\cos^2α+\cos^2β-2\cosα\cosβ\cosγ} $, where $α(β)$ is the angle between spin {\bf S} and position {\bf r}(momentum { \bf P}) and $γ$ is the angle between {\bf r} and {\bf P}. These findings are manifested in a much larger system. The spin response depends on underlying spin structures. A linearly polarized laser pulse creates a dip in a uniform inplane-magnetized thin film, but has little effects on \neel and Bloch walls. Both right- and left- circularly polarized light ($σ^+$ and $σ^-$) have stronger but different effects in both uniform spin domains and Neel walls. While $σ^+$ light creates a basin of spins pointing down, $σ^-$ light creates a mound of spins pointing up. In the vicinity of the structure spins are reversed, similar to the experimental observation. $σ^+$ light has a dramatic effect, disrupting spins in Bloch walls. By contrast, $σ^-$ light has a small effect on Bloch walls because $σ^-$ only switches down spins up and once the spins already point up, there is no major effect.

description: A clonogenic assay is a biological technique for calculating the Surviving Fraction (SF) that quantifies the anti-proliferative effect of treatments on cell cultures: this evaluation is often performed via manual counting of cell colony-forming units. Unfortunately, this procedure is error-prone and strongly affected by operator dependence. Besides, conventional assessment does not deal with the colony size, which is generally correlated with the delivered radiation dose or administered cytotoxic agent. Relying upon the direct proportional relationship between the Area Covered by Colony (ACC) and the colony count and size, along with the growth rate, we propose MF2C3, a novel computational method leveraging spatial Fuzzy C-Means clustering on multiple local features (i.e., entropy and standard deviation extracted from the input color images acquired by a general-purpose flat-bed scanner) for ACC-based SF quantification, by considering only the covering percentage. To evaluate the accuracy of the proposed fully automatic approach, we compared the SFs obtained by MF2C3 against the conventional counting procedure on four different cell lines. The achieved results revealed a high correlation with the ground-truth measurements based on colony counting, by outperforming our previously validated method using local thresholding on L*u*v* color well images. In conclusion, the proposed multi-feature approach, which inherently leverages the concept of symmetry in the pixel local distributions, might be reliably used in biological studies.

description: In this article aspects of photon-photon physics related to the structure of real and virtual photons are reviewed. A re-calculation of the virtual photon-photon box is performed and some discrepancies in the literature are clarified. A useful compilation of various relevant limits derived from the most general expressions is provided. Furthermore, structure functions of spin-averaged, transverse and longitudinal virtual target photons are defined and discussed. Finally, the factorization of two-photon processes in the Bjorken limit is demonstrated to hold also for the case of virtual target photons.

description: Prior to 1996, Israelis in collective communities (kibbutzim) shared the costs of raising children equally. This paper examines the impact of the privatization of kibbutzim on fertility behavior among members. We find that fertility declined by 6-15 percent following the shift to privatization. In light of the massive change in financial costs associated with childbearing due to privatization, our results suggest that financial considerations may be a more modest factor in fertility decisions than generally regarded.

description: This paper presents a review of financial economics literature and offers a comprehensive discussion and systematisation of determinants of financial capital use. In congruence with modern financial literature, it is acknowledged here that real and financial capital decisions are interdependent. While the fundamental role of the (unconstrained) demand for real capital in the demand for finance is acknowledged, the deliverable focuses on three complementary categories of the determinants of financial capital use: i) capital market imperfections; ii) factors mitigating these imperfections or their impacts; and iii) firm- and sector-related factors, which alter the severity of financial constraints and their effects. To address the question of the optimal choice of financial instruments, theories of firm capital structure are reviewed. The deliverable concludes with theory-derived implications for agricultural and non-agricultural rural business’ finance.

description: Zaprionus indianus Gupta (Diptera: Drosophilidae) is a successful invasive drosophilid that is currently impacting fig production in Mexico and Brazil. Very few studies have examined the improvement of trapping strategies for this pest. Here, we compared visual responses of Z. indianus to different colors and olfactory cues. Orange and brown colored traps were among the most attractive in choice and no-choice tests, with violet and white being the least attractive colors. Orange traps with brown circles around the access holes were more attractive than uniformly orange traps. Apple cider vinegar was significantly more attractive to adults than sugar cane vinegar or grape juice but was not significantly more attractive than white wine and red wine vinegars. Captures of Z. indianus in apple cider vinegar-baited traps were not improved by the addition of grape, pineapple or apple juices, or when compared against a sucrose solution or grape juice fermented with Saccharomyces cerevisiae, or grape juice fermented with Candida tropicalis. Pairwise comparisons of Z. indianus attraction to S. cerevisiae and C. tropicalis indicated a high dependence on the growth media used. Orange traps with brown circles baited with apple cider vinegar may prove useful for monitoring this pest under field conditions.

description: The first detection of gravitational waves (GWs) from the binary neutron star (NS) inspiral GW170817 has opened a unique channel for probing the fundamental properties of matter at supra-nuclear densities inaccessible elsewhere in the Universe. This observation yielded the first constraints on the equation of state (EoS) of NS matter from the GW imprint of tidal interactions. Tidal signatures in the GW arise from the response of a matter object to the spacetime curvature sourced by its binary companion. They crucially depend on the EoS and are predominantly characterised by the tidal deformability parameters $Λ_{\ell}$, where $\ell=2,3$ denotes the quadrupole and octupole respectively. As the binary evolves towards merger, additional dynamical tidal effects become important when the orbital frequency approaches a resonance with the stars' internal oscillation modes. Among these modes, the fundamental ($f_\ell$-)modes have the strongest tidal coupling and can give rise to a cumulative imprint in the GW signal even if the resonance is not fully excited. Here we present the first direct constraints on fundamental oscillation mode frequencies for GW170817 using an inspiral GW phase model with an explicit dependence on the $f$-mode frequency and without assuming any relation between $f_\ell$ and $Λ_\ell$. We rule out anomalously small values of $f_\ell$ and, for the larger companion, determine a lower bound on the $f_2$-mode ($f_3$-mode) frequency of $\geq 1.39$ kHz ($\geq 1.86$ kHz) at the 90\% credible interval (CI). We then show that networks of future GW detectors will be able to measure $f$-mode frequencies to within tens of Hz from the inspiral alone. Such precision astroseismology will enable novel tests of fundamental physics and the nature of compact binaries.

description: This paper provides a synthesis of the empirical literature on the key issues in agricultural and rural labour markets since the 1960s, drawing mainly upon studies from the United States and the European Union, but also including relevant material from developing countries. The contribution of this meta-analysis lies in its unique structure as it covers the main research questions that have been addressed in the literature and includes the most cited papers from the American Journal of Agricultural Economics, Journal of Agricultural Economics, European Review of Agricultural Economics and Agricultural Economics as well as other reports and EU-funded projects. Each research question is accompanied by a tabular summary that classifies the individual studies according to the methodology and the variables employed. The heterogeneous conditions across countries, the different research questions and methodologies, and the type of data employed have sometimes led to conflicting results. Nevertheless, by comparing the results, it is possible to assess the significance and the direction of the determinants of rural labour allocation and its adjustments, and thus contribute to a better understanding of the functioning of rural labour markets. Lastly, by recognising the importance of the institutional framework, the paper provides useful policy insights.
