description: We study the behavior of static, spherically symmetric solutions to the field equations of scalar-tensor theories (STT) of gravity belonging to the Bergmann-Wagoner-Nordtvedt class, in the presence of an electric and/or magnetic charge. This class of theories includes the Brans-Dicke, Barker and Schwinger STT as well as nonminimally coupled scalar fields with an arbitrary parameter $ξ$. The study is restricted to canonical (nonphantom) versions of the theories and scalar fields without a self-interaction potential. Only radial (monopole) perturbations are considered as the most likely ones to cause an instability. The static background solutions contain naked singularities, but we formulate the boundary conditions in such a way that would preserve their meaning if a singularity is smoothed, for example, due to quantum gravity effects. These boundary conditions look more physical than those used by other authors. Since the solutions of all STT under study are related by conformal transformations, the stability problem for all of them reduces to the same wave equation, but the boundary conditions for perturbations (and sometimes the boundaries themselves) are different in different STT, which affects the stability results. The stability or instability conclusions are obtained for different branches of solutions in the theories under consideration and are presented in a table form.

description: We investigate the radiation from a bunch of relativistic electrons moving along the cylindrical waveguide axis, assuming that the waveguide is partially loaded by a medium with periodic dielectric permittivity and magnetic permeability. The spectral distribution of the radiation energy flux through the cross section of the waveguide is studied at large distances from the medium. The analysis is based on the corresponding exact solution of Maxwell equations for the case of a single electron moving along the waveguide axis. The results of numerical calculations are presented in the special case of layered medium consisting of a finite number of dielectric plates separated by vacuum gaps. We show that under certain conditions on the problem parameters the quasi-coherent Cherenkov radiation generated by the electron bunch inside the plates is self-amplified at certain waveguide modes. A visual explanation of this phenomenon is provided that reproduces the main features to rather good accuracy.

description: We evaluate dynamic interaction between four expert forecasts, futures prices, and realized cash hog prices. Lag structures of three variable vector autoregression indicate dynamic interaction among futures and cash markets and that past forecasts impact cash prices. Causal analysis of model residuals reveals contemporaneous causation of cash prices by futures prices and by some forecasts, and in all cases indicates causal structures consistent with the chronological ordering of prior day futures, subsequent forecasts, and cash prices realized one quarter later. Error decompositions following this ordering indicate expert forecasts are somewhat more important to futures and cash markets than previously believed.

description: We examine price transmissions among farm, wholesale and retail U.S. beef markets using two types of retail level price data, one collected by the Bureau of Labor Statistics (BLS) and the other one collected at the point of sale using electronic scanners. Although some evidence suggests that BLS prices are bias (do not account for volume sales and discounted prices), we find no evidence of asymmetric price transmissions in the response of retail prices to changes in upstream prices. Our findings have important implications for the U.S. beef market efficiency. Since retailer price adjustments to farm and wholesale price changes are symmetric, the U.S. beef market is not as inefficient as found in previous studies.

description: We perform the first lattice calculation on the semileptonic decay of $J/ψ$ using the (2+1)-flavor Wilson-clover gauge ensembles generated by CLQCD collaboration. Three gauge ensembles with different lattice spacings, from 0.0519 fm to 0.1053 fm, and pion masses, $m_π\sim$ 300 MeV, are utilized. After a naive continuum extrapolation using three lattice spacings, we obtain $\operatorname{Br}(J/ψ\rightarrow D_s eν_e)=1.90(6)(5)_{V_{cs}}\times 10^{-10}$ and $\operatorname{Br}(J/ψ\rightarrow D eν_e)=1.21(6)(9)_{V_{cd}}\times 10^{-11}$, where the first errors are statistical, and the second come from the uncertainties of CKM matrix element $V_{cs(d)}$. The ratios of the branching fractions between lepton $μ$ and $e$ are also calculated as $R_{J/ψ}(D_s)=0.97002(8)$ and $R_{J/ψ}(D)=0.97423(15)$ after performing a continuum limit including only $a^2$ term. The ratios provide necessary theoretical support for the future experimental test of lepton flavor universality.

title: Cancer biomarker discovery without assumptions about cancer biology: The double dip design
Creators: name: Baker, Stuart G.
Publisher: name: Organisms. Journal of Biological Sciences
Year: 2020

description: The biomarker pipeline to improve cancer screening begins with the discovery and validation of a cancer prediction model involving markers for the early detection of cancer in asymptomatic persons. Unfortunately, this biomarker pipeline has led to few markers for clinical use. An unappreciated reason for this lack of success is that standard discovery uses a convenience sample of specimens from persons with symptomatic cancer and no cancer. Standard discovery in a convenience sample implicitly makes a questionable assumption about cancer biology, namely, that highly predictive biomarkers in asymptomatic persons persist until symptomatic cancer arises when they outperform markers associated with symptomatic cancer. If cancer arises from a sequence of driver mutations and biomarkers are associated with driver mutations, this assumption may be plausible. However, if cancer arises primarily from changes in the microenvironment, the assumption is questionable. To circumvent the need for this assumption, I propose the double dip design. The double dip design starts with standard discovery in a convenience sample (as this is standard practice) followed by the usual validation sample of stored specimens from asymptomatic persons. If validation fails, it re-uses the original validation sample of stored specimens for more relevant biomarker discovery, followed by a second validation sample of stored specimens from asymptomatic persons. Recently developed statistical methods to reduce validation sample size make the double dip design feasible.

Both forms have a characteristic foliation whose leaves are contact manifolds. These foliations are transverse and complementary. Further differential objects are associated to Contact Pairs: two commuting Reeb vector fields, Legendrian curves on $M$ and two Lie brackets on $\mathcal{C}^{\infty}(M) $. We give a local model and several existence theorems on nilpotent Lie groups, nilmanifolds, bundles over the circle and principal torus bundles.

description: Agricultural futures price features stochastic volatility, seasonal spot price volatility, and stochastic cost-of-carry. We propose a single comprehensive model that inludes all these features. We apply the proposed model to analyze the corn futures market from January 3rd, 1989, to December 31st, 2008. We conduct parameter estimation using Markov chain Monte Carlo (MCMC) with a novel dynamic tuning scheme. We also employ a parallel MCMC scheme for state variable estimation. Parameter estimates and model errors indicate the comprehensive model to be e_x000B_ective for modeling corn futures.

description: Differences in physical quality characteristics among classes or types of wheat are often reflected in global cash wheat prices in general, and in wheat prices and sales involving major Black Sea Region exporters Russia, Ukraine and Kazakhstan in particular. Black Sea Region wheat export markets appear to be somewhat associated with each in other in terms of price dynamics, while still exhibiting important differences. Differences in wheat class quality characteristics and logistical-transportation factors play an important role in determining the competitive, cointegrated nature of world and Black Sea Region wheat market price relationships, along with the dynamics of changing wheat supply-demand balances. Black Sea Region wheat prices display some degree of price interrelatedness for milling quality wheat, but not complete uniformity. Ukraine milling wheat export prices show evidence of being cointegrated with German milling wheat export prices, but less so with with those of Russia. Russian milling wheat export prices appear to be cointegrated with both U.S. hard red winter and soft red winter wheat export prices, but less so with those of the Ukraine. Kazakhstan milling wheat export prices show evidence of being somewhat associated with Russian milling wheat export prices, but not so with those in Ukraine.

description: Currents of the single-electron transistors driven by time-dependent fields via external dissipative circuits are investigated theoretically. By expressing the external circuit in terms of driven harmonic oscillators and using the reduced-density operator method, we derive time- and environment-dependent tunneling rates in the regime of sequential tunneling and present expressions for both displacement and tunneling currents with these tunneling rates. It is found that the dissipative environments affect tunneling currents in two ways; the determination of driving voltages at tunneling junctions and the depletion of particle-hole distribution functions. Considering a simple dissipative circuit, we discuss the effects of the environment on tunneling currents in both static and time-dependent cases.

description: Precision health, increasingly supported by digital technologies, is a domain of research that broadens the paradigm of precision medicine, advancing everyday healthcare. This vision goes hand in hand with the groundbreaking advent of artificial intelligence (AI), which is reshaping the way we diagnose, treat, and monitor both clinical subjects and the general population. AI tools powered by machine learning have shown considerable improvements in a variety of healthcare domains. In particular, reinforcement learning (RL) holds great promise for sequential and dynamic problems such as dynamic treatment regimes and just-in-time adaptive interventions in digital health. In this work, we discuss the opportunity offered by AI, more specifically RL, to current trends in healthcare, providing a methodological survey of RL methods in the context of precision and digital health. Focusing on the area of adaptive interventions, we expand the methodological survey with illustrative case studies that used RL in real practice.

description: To analyze linear field equations on a locally homogeneous spacetime by means of separation of variables, it is necessary to set up appropriate harmonics according to its symmetry group. In this paper, the harmonics are presented for a spatially compactified Bianchi II cosmological model -- the nilgeometric model. Based on the group structure of the Bianchi II group (also known as the Heisenberg group) and the compactified spatial topology, the irreducible differential regular representations and the multiplicity of each irreducible representation, as well as the explicit form of the harmonics are all completely determined. They are also extended to vector harmonics. It is demonstrated that the Klein-Gordon and Maxwell equations actually reduce to systems of ODEs, with an asymptotic solution for a special case.

description: The study evaluates the impact of four public reports and one private report on the cotton market: Export Sales, Crop Progress, World Agricultural Supply and Demand Estimates (WASDE), Perspective Planting, and Cotton This Month. The best fitting GARCH models are selected separately for the daily cotton futures close-to-close, close-to-open, and open-to-close returns from January 1995 through January 2012. In measuring the report effects, we control for the day-of-week, seasonality, stock level, and weekend-holiday effects on cotton futures returns. We find statistically significant impact of the WASDE and Perspective Planting reports on cotton returns. Furthermore, results indicate that the progression of market reaction varied across reports.

description: If the inflaton is a heavy scalar field, it may equilibrate slower than some other degrees of freedom, e.g. non-Abelian gauge bosons. In this case, perturbations in the inflaton field and in a thermal plasma coexist from a given moment onwards. We derive a gauge-invariant set of three coupled equations governing the time evolution of such a system. Despite singular coefficients, a reliable numerical solution can be obtained for a long time period, starting from phase oscillations inside the Hubble horizon, and extending until acoustic oscillations in a radiation-dominated universe. Benchmarks are illustrated from a "weak regime", where perturbations have a quantum-mechanical origin but get dissipated by interactions with the plasma. Among applications of our formalism could be inhomogeneity-induced nucleations in post-inflationary phase transitions, and the production of scalar-induced gravitational waves.

description: Particles moving along curved trajectories will diffuse if the curvature fluctuates sufficiently in either magnitude or orientation. We consider particles moving at a constant speed with either a fixed or with a Gaussian distributed curvature magnitude. At small speeds the diffusivity is independent of the speed. At larger particle speeds, the diffusivity depends on the speed through a novel exponent. We apply our results to intracellular transport of vesicles. In sharp contrast to thermal diffusion, the effective diffusivity increases with vesicle size and so may provide an effective means of intracellular transport.

description: The study examines if a storage strategy based on the cash-futures basis (the basis strategy) has been profitable over the 1975-2012 crop years for Illinois corn and soybeans. The study first examines the means and standard deviations of annual net storage returns obtained from hedged and unhedged storage when routinely storing each year and when using the basis strat- egy. For both the period of higher commodity prices since 2005 and the pre-2006 period, the basis strategy is found to (1) improve net returns to hedged but not unhedged storage and (2) lower the return risk for both hedged and unhedged storage. Previous studies have not exam- ined the basis strategy's impact on the return risk for unhedged storage. To further investigate the performance of the basis strategy in these two periods, the performance of the expected net return to storage in forecasting the observed net storage return is examined. Given the panel structure of the data, a Fixed E_x000B_ects (FE) model was chosen to estimate since the re- gion speci_x000C_c e_x000B_ects are of interest. However, signi_x000C_cant cross-equation correlations are found in the disturbances, a characteristic not investigated in previous studies. Thus, a Fixed E_x000B_ects (FE) Panel Seemingly Unrelated Regressions (PSUR) is estimated. Forecast performance of the observed net storage return by the expected net storage return was found to be unbiased in the pre-2006 period. Forecast performance deteriorated somewhat in the post-2006 period as some forecasts were found to be biased. The decline in forecast performance is consistent with during some of the years since 2006.

description: Cyperus neocooperi Reynders, nom. nov.
 Basionym: Pycreus cooperi C.B.Clarke in W.H.Harvey & auct. suc. (eds.), Fl. Cap. 7: 160 (Clarke 1897) ≡ Cyperus cooperi (C.B.Clarke) Kükenthal (1934: 68) nom. illeg., non. Cyperus cooperi (C.B.Clarke) K.Schum. (1900: 328).
 Type:— SOUTH AFRICA, Orange Free State, 17 January 1861, T. Cooper 912 (holotype K!).
 Description: — Clarke (1897: 160).
 Note: — Cyperus neocooperi is very similar to C. aethiops, which has smaller glumes and a more northerly, afromontane distribution. Possibly, both could even be considered as conspecific. Cyperus aethiops belongs to Cyperus section Pycreus (C. sect. Polystachyi Kük., nom. illeg.), and C. neocooperi also fits in this group based on its elongated elliptic nutlets. Kükenthal (1936) placed C. neocooperi species in the very heterogenous C. sect. Lancei based on its rather large and dark glumes. However, blackish glumes are correlated with Cyperus species growing at higher elevation and originated multiple times within the genus, also, glume size does not seem to be reliable for infrageneric classification (Reynders 2013).

description: We study the dynamics of entanglement in the scaling limit of the Ising spin chain in the presence of both a longitudinal and a transverse field. We present analytical results for the quench of the longitudinal field in critical transverse field which go beyond current lattice integrability techniques. We test these results against a numerical simulation on the corresponding lattice model finding extremely good agreement. We show that the presence of bound states in the spectrum of the field theory leads to oscillations in the entanglement entropy and suppresses its linear growth on the time scales accessible to numerical simulations. For small quenches we determine exactly these oscillatory contributions and demonstrate that their presence follows from symmetry arguments. For the quench of the transverse field at zero longitudinal field we prove that the Rényi entropies are exactly proportional to the logarithm of the exponential of a time-dependent function, whose leading large-time behaviour is linear, hence entanglement grows linearly. We conclude that, in the scaling limit, linear growth and oscillations in the entanglement entropies can not be simply seen as consequences of integrability and its breaking respectively.

description: We present completions of mock theta functions to harmonic weak Maass forms of weight $1/2$ and algebraic formulas for the coefficients of mock theta functions. We give several harmonic weak Maass forms of weight $1/2$ that have mock theta functions as their holomorphic part. Using these harmonic weak Maass forms and the Millson theta lift we compute finite algebraic formulas for the coefficients of the appearing mock theta functions in terms of traces of singular moduli.

title: Marxism and the Crisis in Modern Biology

description: Modern biology, especially biomedical research, is currently embroiled in crisis. This crisis is not unsurprising considering the bourgeois culture and philosophy that has guided scientific research since the Molecular Biology revolution and aided by the increasing public-private partnerships. The resolution of this crisis can only be achieved through a radical shift in how we understand and practice science, and the Marxist philosophy of dialectical materialism can provide us with the necessary tools to do so. In this paper, I provide a brief overview of the development of dialectical materialism and its application over the years to understanding the natural world. I also show that biologists have also independently adopted similar views as research has progressed over the years. Lastly, I argue that the epistemological crisis and the subsequent crisis observed in the practice in science are two sides of the same coin, and that Marxist philosophy can help break out of this vicious cycle.

description: The following contribution introduces a concept that employs Large Language Models (LLMs) and a chatbot interface to enhance SPARQL query generation for ontologies, thereby facilitating intuitive access to formalized knowledge. Utilizing natural language inputs, the system converts user inquiries into accurate SPARQL queries that strictly query the factual content of the ontology, effectively preventing misinformation or fabrication by the LLM. To enhance the quality and precision of outcomes, additional textual information from established domain-specific standards is integrated into the ontology for precise descriptions of its concepts and relationships. An experimental study assesses the accuracy of generated SPARQL queries, revealing significant benefits of using LLMs for querying ontologies and highlighting areas for future research.

description: Adaptive meshing is a fundamental component of adaptive finite element methods. This includes refining and coarsening meshes locally. In this work, we are concerned with the red-green-blue refinement strategy in two dimensions and its counterpart - coarsening. In general, coarsening algorithms are mostly based on an explicitly given refinement history. In this work, we present a coarsening algorithm on adaptive red-green-blue meshes in two dimensions without explicitly knowing the refinement history. To this end, we examine the local structure of these meshes, find an easy-to-verify criterion to adaptively coarsen red-green-blue meshes and prove that this criterion generates meshes with the desired properties. We present a MATLAB implementation built on the red-green-blue refinement routine of the ameshref-package.

description: In view of future plans for accurate measurements of the theoretically clean branching ratios Br(K+ -> pi+ nu nu) and Br(KL -> pi0 nu nu), that should take place in the next decade, we collect the relevant formulae for quantities of interest and analyze their theoretical and parametric uncertainties. We point out that in addition to the angle beta in the unitarity triangle (UT) also the angle gamma can in principle be determined from these decays with respectable precision and emphasize in this context the importance of the recent NNLO QCD calculation of the charm contribution to K+ -> pi+ nu nu and of the improved estimate of the long distance contribution by means of chiral perturbation theory. In addition to known expressions we present several new ones that should allow transparent tests of the Standard Model (SM) and of its extensions. While our presentation is centered around the SM, we also discuss models with minimal flavour violation and scenarios with new complex phases in decay amplitudes and meson mixing. We give a brief review of existing results within specific extensions of the SM, in particular the Littlest Higgs Model with T-parity, Z' models, the MSSM and a model with one universal extra dimension. We derive a new "golden" relation between B and K systems that involves (beta,gamma) and Br(KL -> pi0 nu nu) and investigate the virtues of (R_t,beta), (R_b,gamma), (beta,gamma) and (etabar,gamma) strategies for the UT in the context of K -> pi nu nu decays with the goal of testing the SM and its extensions.

Amplitude chimera and chimera death induced by external dynamical agents

description: We report the emergence of stable amplitude chimeras and chimera death in a two-layer network where one layer has an ensemble of identical nonlinear oscillators interacting directly through local coupling and indirectly through dynamic agents that form the second layer. The nonlocality in the interaction among the dynamical agents in the second layer induces different types of chimera related dynamical states in the first layer. The amplitude chimeras developed in them are found to be extremely stable, while chimera death states are prevalent for increased coupling strengths. The results presented are for a system of coupled Stuart-Landau oscillators and can in general represent systems with short-range interactions coupled to another set of systems with long range interactions. In this case, by tuning the range of interactions among the oscillators or the coupling strength between the two types of systems, we can control the nature of chimera states and the system can be restored to homogeneous steady states. The dynamic agents interacting nonlocally with long-range interactions can be considered as a dynamic environment or medium interacting with the system. We indicate how the second layer can act as a reinforcement mechanism on the first layer under various possible interactions for desirable effects.
