description: We point out that the kinematical twist-3 contributions to the DVCS amplitude, required to restore electromagnetic gauge invariance of the twist-2 amplitude up to O(t/q^2), can be understood as a spin rotation applied to the twist-2 quark density matrix in the target. This allows for a compact representation of the twist-3 effects, as well as for a simple physical interpretation.

description: A persisting obstacle in human immunology is that blood-derived leukocytes are notoriously difficult to manipulate at the RNA level. Therefore, our knowledge about immune-regulatory RNA-networks is largely based on tumour cell-line and rodent knockout models, which do not fully mimic human leukocyte biology. Here, we exploit straightforward cell penetrating peptide (CPP) chemistry to enable efficient loss-of-function phenotyping of regulatory RNAs in primary human blood-derived cells. The classical CPP octaarginine (R8) enabled antisense peptide-nucleic-acid (PNA) oligomer delivery into nearly 100% of human blood-derived macrophages without apparent cytotoxicity even up to micromolar concentrations. In a proof-of-principle experiment, we successfully de-repressed the global microRNA-155 regulome in primary human macrophages using a PNA-R8 oligomer, which phenocopies a CRISPR-Cas9 induced gene knockout. Interestingly, although it is often believed that fairly high concentrations (μM) are needed to achieve antisense activity, our PNA-R8 was effective at 200 nM. RNA-seq characterized microRNA-155 as a broad-acting riboregulator, feedback restraining a late myeloid differentiation-induced pro-inflammatory network, comprising MyD88-signalling and ubiquitin-proteasome components. Our results highlight the important role of the microRNA machinery in fine-control of blood-derived human phagocyte immunity and open the door for further studies on regulatory RNAs in difficult-to-transfect primary human immune cells.

description: Large logarithms that arise in cross sections due to the collinear and soft singularities of QCD are traditionally treated using parton showers or analytic resummation. Parton showers provide a fully-differential description of an event but are challenging to extend beyond leading logarithmic accuracy. On the other hand, resummation calculations can achieve higher logarithmic accuracy but often for only a single observable. Recently, there have been many resummation calculations that jointly resum multiple logarithms. Here we investigate the benefits and limitations of joint resummation in a case study, focussing on the family of $e^+e^-$ event shapes called angularities. We calculate the cross section differential in n angularities at next-to-leading logarithmic accuracy. We investigate whether reweighing a flat phase-space generator to this resummed prediction, or the corresponding distributions from Herwig and Pythia, leads to improved predictions for other angularities. We find an order of magnitude improvement for n = 2 over n = 1, highlighting the benefit of joint resummation, but diminishing returns for larger values of n.

description: We present a definition of the four-dimensional helicity (FDH) regularization scheme valid for two or more loops. This scheme was previously defined and utilized at one loop. It amounts to a variation on the standard 't Hooft-Veltman scheme and is designed to be compatible with the use of helicity states for "observed" particles. It is similar to dimensional reduction in that it maintains an equal number of bosonic and fermionic states, as required for preserving supersymmetry. Supersymmetry Ward identities relate different helicity amplitudes in supersymmetric theories. As a check that the FDH scheme preserves supersymmetry, at least through two loops, we explicitly verify a number of these identities for gluon-gluon scattering (gg to gg) in supersymmetric QCD. These results also cross-check recent non-trivial two-loop calculations in ordinary QCD. Finally, we compute the two-loop shift between the FDH coupling and the standard MS-bar coupling, alpha_s. The FDH shift is identical to the one for dimensional reduction. The two-loop coupling shifts are then used to obtain the three-loop QCD beta function in the FDH and dimensional reduction schemes.

description: Lithium-intercalated layered transition-metal oxides, LixTMO2, brought about a paradigm change in rechargeable batteries in recent decades and show promise for use in memristors, a type of device for future neural computing and on-chip storage. Thermal transport properties, although being a crucial element in limiting the charging/discharging rate, package density, energy efficiency, and safety of batteries as well as the controllability and energy consumption of memristors, are poorly managed or even understood yet. Here, for the first time, we employ quantum calculations including high-order lattice anharmonicity and find that the thermal conductivity k of LixTMO2 materials is significantly lower than hitherto believed. More specifically, the theoretical upper limit of k of LiCoO2 is 6 W/m-K, 2-6 times lower than the prior theoretical predictions. Delithiation further reduces k by 40-70% for LiCoO2 and LiNbO2. Grain boundaries, strains, and porosity are yet additional causes of thermal-conductivity reduction, while Li-ion diffusion and electrical transport are found to have only a minor effect on phonon thermal transport. The results elucidate several long-standing issues regarding the thermal transport in lithium-intercalated materials and provide guidance toward designing high-energy-density batteries and controllable memristors.

description: Using equilibrium hydrodynamics with initial conditions for the energy and net baryon number densities from the perturbative QCD + saturation model, a good simultaneous description of the measured pion, kaon and (anti)proton spectra in central Au+Au collisions at $\sqrt s=130 A$GeV is found with a single decoupling temperature $\Tdec=150...160$ MeV. The interplay between the resonance content of the EoS and the development of the transverse flow leads to inverse slopes and $$ of hadrons which increase with decreasing $\Tdec$. The origin of this result is discussed.

description: Human beings are creatures of habit. In their daily life, people tend to repeatedly consume similar types of food items over several days and occasionally switch to consuming different types of items when the consumptions become overly monotonous. However, the novel and repeat consumption behaviors have not been studied in food recommendation research. More importantly, the ability to predict daily eating habits of individuals is crucial to improve the effectiveness of food recommender systems in facilitating healthy lifestyle change. In this study, we analyze the patterns of repeat food consumptions using large-scale consumption data from a popular online fitness community called MyFitnessPal (MFP), conduct an offline evaluation of various state-of-the-art algorithms in predicting the next-day food consumption, and analyze their performance across different demographic groups and contexts. The experiment results show that algorithms incorporating the exploration-and-exploitation and temporal dynamics are more effective in the next-day recommendation task than most state-of-the-art algorithms.

description: The only string models known to reproduce the Minimal Supersymmetric Standard Model in the low energy effective field theory are those constructed in the free fermionic formulation. We demonstrate the existence of quasi-realistic free fermionic heterotic-string models in which supersymmetric singlet flat directions do not exist. This raises the possibility that supersymmetry is broken perturbatively in such models by the one-loop Fayet-Iliopoulos term. We show, however, that supersymmetric flat directions that utilize VEVs of some non-Abelian fields in the massless string spectrum do exist in the model. We argue that hidden sector condensates lift the flat directions and break supersymmetry hierarchically.

description: This article questions whether the WTO regime is the most appropriate institution for governing the global agriculture and trade in the wake of the problems that our world faces today. Specifically, climate change, potentially unsustainable agricultural practices, food insecurity in less developed countries (LDC), and expected imbalance in the global food demand and supply by 2050 are emerging as major challenges to humanity and the WTO while it is still struggling to resolve issues (related to agricultural protectionism that arises from the special facets of agriculture) of the 20th century while completely lacking the capacity to tackle such new global issues of the 21st century. Given this outmoded institution, the primary objective of this article is to propose that a new structure of governance is needed so as to exclusively and effectively deal with problems arising from the interactions of the problems related to climate change, agricultural sustainability, food security, and trade. Four broad rationales are offered in this article that support the creation of a new system of governance for the global agriculture: (i) inability of the WTO in resolving agricultural protectionism of the 20th century; (ii) potential adverse effects of liberalized agricultural trade on the environment (climate change and sustainability of food production) and hunger/poverty in LDCs; (iii) global public good properties associated with the problems of climate change, sustainability, and food security and consequent need for collective action (transnational cooperation) at the global level, and (iv) the need to address the interactions among climate change, sustainability, and food security holistically in a concerted manner. We suggest the World Agriculture Organization (WAO) as a possible form of global institution that will play a central role in the new system of governance for the global agriculture.
Efficacy of Sumac in Blood Pressure Modulation: A Narrative Review

description: Background: Hypertension is a prevalent cardiovascular risk factor, contributing to various debilitating conditions. Although pharmacological interventions are available, the side effects of medications negatively affect individuals’ adherence and quality of life. Plants from the genus Rhus, also known as sumac, have been traditionally used to treat cardiovascular and gastrointestinal diseases. Purpose: This narrative review aimed to assess the efficacy of sumac in blood pressure management through a comprehensive review of available clinical and pre-clinical trials. Methods: A systemic search of databases Medline, Excerpta Medica dataBASE and Cumulative Index to Nursing and Allied Health Literature was conducted up to March 2024. Results: Among 41 screened studies, five studies (four clinical and one pre-clinical) were included. All clinical trials demonstrated that sumac administration caused a significant reduction in systolic blood pressure (SBP). Sumac was effective in the reduction of diastolic blood pressure (DBP) in two studies. A pre-clinical study also showed a significant reduction in both SBP and DBP alongside increased nitric oxide expression. Conclusion: Sumac could have therapeutic and preventative effects on hypertension, potentially attributed to its antioxidant properties and ability to enhance nitric oxide production. However, further studies with longer duration and exploration of different sumac species are warranted to validate these findings and establish their therapeutic efficacy in blood pressure modulation. This review provides a foundation for future clinical investigations into sumac's role in hypertension management.

description: The superconducting transition leads to a sharp resistance drop in a temperature interval that can be a small fraction of the critical temperature T$_c$. A superconductor exactly at T$_c$ is thus very sensitive to all kinds of thermal perturbations, including the heat dissipated by the measurement current. We show that the interaction between electrical and thermal currents leads to a sizeable imaginary impedance at frequencies of order of tens of Hz at the resistive transition of single crystals of the layered material 2H-NbSe$_2$. We explain the result using models developed for transition edge sensors. By measuring under magnetic fields and at high currents, we find that the imaginary impedance is strongly influenced by the heat associated with vortex motion and out-of-equilibrium quasiparticles.

description: As the gap in income between urban and rural residents bigger and bigger, based on the data from 1978 to 2007, this paper makes an empirical study of the dynamic relation between the fixed assets investment and the difference in income between urban and rural residents. The outcome from the study indicates a long-term balance exists between the investment rate of the fixed assets and the difference in income between urban and rural residents. A short-term deviation from the balance can be adjusted through long time. To a certain extent, city-oriented fixed assets investment policy is the main cause of the big gap in income between urban and rural residents. The big gap in income between urban and rural residents in turn reinforces their social status, thus further strengthening the city-oriented instead of countryside-oriented fixed assets investment policy. Based on that, this paper puts forward some suggestions on adjusting the fixed assets investment policy so as to shorten the difference in income between urban and rural residents and realize the goal of harmonious development between city and countryside.

description: SU(3) symmetry relations between the octet baryons are introduced in order to connect both the unpolarized and polarized quark distributions of the octet baryons with those of the nucleon. Two different parametrizations of the nucleon quark distributions are used. A new scenario of quark flavor and spin structure of the $Λ$ is found and compared with two other models: a perturbative QCD based analysis and a quark diquark model. The $u$ and $d$ quarks inside the $Λ$ are predicted to be positively polarized at large Bjorken variable $x$ in the new scenario. By using an approximate relation connecting the quark fragmentation functions with the quark distributions, the hadron polarizations of the octet baryons in $e^+e^-$-annihilation, polarized charged lepton deep inelastic scattering (DIS) processes, and neutrino (antineutrino) DIS processes are predicted. The predictions for $Λ$ polarizations in several processes are compatible with the available data at large fragmentation momentum fraction $z$, and support the prediction of positively polarized $u$ and $d$ quarks inside the $Λ$ at large $x$. Predictions for Drell-Yan processes from $Σ^{\pm}$ and $Ξ^-$ beams on an isoscalar target are also given and discussed.

description: The purpose of this paper is to analyze whether the aggregation problem really matters in estimating the Korean demand for imported beef. This paper incorporates the aggregation bias in the demand system and tests whether the aggregation bias is statistically significant with two models: an unrestricted model with aggregation bias variables and a restricted model without the bias variables. The impact of the aggregation bias is also analyzed by comparing the elasticities of the two models. According to the Wald test, the hypothesis of no aggregation bias is rejected and the LR (Likelihood Ratio) test shows that the unrestricted model is statistically better than the restricted model. However, the impact of the aggregation bias on the demand system for imported beef is not so severe in that the elasticities of the two models are not so different and the elasticities of aggregation bias variables are insignificant. This paper utilizes imported beef data of two types (frozen and non-frozen) from USA, Canada, Australia and Rest of World. The aggregation bias is decomposed into country effect, product effect and interaction effect.
Precision Electroweak Tests of the Standard Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The present status of precision electroweak data is reviewed. These data include measurements of e+e- -> f+fbar, taken at the Z resonance at LEP, which are used to determine the mass and width of the Z boson. In addition, measurements have also been made of the forward-backward asymmetries for leptons and heavy quarks, and also the final state polarisation of the tau-lepton. At SLAC, where the electron beam was polarised, measurements were made of the left-right polarised asymmetry, A_LR, and the left-right forward-backward asymmetries for b and c quarks. The mass, MW, and width, GW, of the W boson have been measured at the Tevatron and at LEP, and the mass of the top quark, Mt, has been measured at the Tevatron. These data, plus other electroweak data, are used in global electroweak fits in which various Standard Model parameters are determined. A comparison is made between the results of the direct measurements of MW and Mt with the indirect results coming from electroweak radiative corrections. Using all precision electroweak data fits are also made to determine limits on the mass of the Higgs boson. The influence on these limits of specific measurements, particularly those which are somewhat inconsistent with the Standard Model, is explored. The data are also analysed in terms of the quasi model-independent epsilon variables. Finally, the impact on the electroweak fits of the improvements in the determination of the W-boson and top-quark masses, expected from the Tevatron Run 2, is examined.

The information will spread quickly when food product harm crisis happens, and the phenomenon that information of product-harm spills over is very common. This article is based on “Frustration-Misbehaving” research paradigm, combined with the information dissemination motivation theory, discusses that the fitness between the consumers and the crisis will promote consumers' dysfunctional customer behavior. The study found that the fitness between the consumers and the crisis has significant effect on consumers' dysfunctional customer behavior, perceived social damage has a mediator effect between fitness and consumers' misbehavior, and the moderating effect of consumers' aggression tendency is significant, but not the emotional tendency. The theoretical contribution and valuable implications of findings for communication of crisis management are discussed at last.

description: This paper describes the application of a laser diffraction technique to the study of electroconvection in nematic liquid crystal cells. It allows a real-time quantitative access to pattern wave lengths and amplitudes. The diffraction profile of the spatial periodic pattern is calculated and compared quantitatively to experimental intensity profiles. For small director tilt amplitudes $ϕ$, the phase grating generated in normally incident undeflected light and the first order term correction from light deflection is derived analytically. It yields an $I\proptoϕ^4$ dependence of the diffracted intensity $I$ on the amplitude of director deflections. For larger director tilt amplitudes, phase and amplitude modulations of deflection of light in the inhomogeneous director field are calculated numerically. We apply the calculations to the determination of the director deflection and measure growth and decay rates of the dissipative patterns under periodic excitation. Real time analysis of pattern amplitudes under stochastic excitation is demonstrated.

description: Efforts to detect low-mass exoplanets using stellar radial velocities (RVs) are currently limited by magnetic photospheric activity. Suppression of convective blueshift is the dominant magnetic contribution to RV variability in low-activity Sun-like stars. Due to convective plasma motions, the magnitude of RV contributions from the suppression of convective blueshift is related to the depth of formation of photospheric spectral lines of a given species used to compute the RV time series. Meunier et al. (2017), used this relation to demonstrate a method for spectroscopic extraction of the suppression of convective blueshift in order to isolate RV contributions, including planetary RVs, that contribute equally to the timeseries for each spectral line. Here, we extract disk-integrated solar RVs from observations over a 2.5 year time span made with the solar telescope integrated with the HARPS-N spectrograph at the Telescopio Nazionale Galileo (La Palma, Canary Islands, Spain). We apply the methods outlined by Meunier et al. (2017). We are not, however, able to isolate physically meaningful contributions of the suppression of convective blueshift from this solar dataset, potentially because our dataset is from solar minimum when the suppression of convective blueshift may not sufficiently dominate activity contributions to RVs. This result indicates that, for low-activity Sun-like stars, one must include additional RV contributions from activity sources not considered in the Meunier et al. (2017) model at different timescales as well as instrumental variation in order to reach the sub-meter per second RV sensitivity necessary to detect low-mass planets in orbit around Sun-like stars.

description: Guangxi Zhuang Autonomous Region is an excellent area for tilapia breeding in China, and the development of tilapia industry has received high attention of both the state and Guangxi government. The foreign exchange earning is an essential industrial form of tilapia industry in Guangxi. Thus, enhancing the competitiveness of export-oriented tilapia processing is of great significance to the development of tilapia industry. On the basis of field survey, this paper analyzed current situation of export-oriented tilapia processing in Guangxi. At present, tilapia processing industry in Guangxi has realized preliminary standardization, large-scale and grouping, but it is still faced with some problems and challenges, such as low industrialization level, no balanced marketing, and imperfect product quality safety monitoring measures. Therefore, it is required to create favorable environment for export-oriented tilapia processing industry in Guangxi through enhancing policy support, increasing financial input and supporting tilapia processing leading enterprises.

description: We present the development of a high $Q$ monolithic silica pendulum weighing 7 mg. The measured $Q$ value for the pendulum mode at 2.2 Hz was $2.0\times10^6$. To the best of our knowledge this is the lowest dissipative mg-scale mechanical oscillator to date. By employing this suspension system, the optomechanical displacement sensor for gravity measurements we recently reported in Phys. Rev. Lett. 122, 071101 (2019) can be improved to realize quantum-noise-limited sensing at several hundred Hz. In combination with the optical spring effect, the amount of intrinsic dissipation measured in the pendulum mode is enough to satisfy requirements for measurement-based quantum control of a massive pendulum confined in an optical potential. This paves the way for not only testing dark matter via quantum-limited force sensors, but also Newtonian interaction in quantum regimes, namely, between two mg-scale oscillators in quantum states, as well as improving the sensitivity of gravitational-wave detectors.

description: Eight-segmented, negative-sense, single-stranded genomic RNAs of influenza A virus are terminated with 5′ and 3′ untranslated regions (UTRs). All segments have highly conserved extremities of 13 and 12 nucleotides at the 5′ and 3′ UTRs, respectively, constructing the viral RNA (vRNA) promoter. Adjacent to the duplex stem of 3 base pairs (bps) between the two conserved strands, additional 1–4 bps are existing in a segment-specific manner. We investigated the roles of the matrix (M) segment-specific base pair between the 14th nucleotide uridine (U14′) of the 5′ UTR and the 13th nucleotide adenosine (A13) of the 3′ UTR by preparing possible vRNA promoters, named vXY, as well as cRNA promoters, named cYX. We analysed their RNA-dependent RNA replication efficiency using the minigenome replicon system and an enzyme assay system in vitro with synthetic RNA promoters. Notably, in contrast to vAC(s) that is a synthetic vRNA promoter with A14′ and C13, base-pair disruption at the complementary RNA (cRNA) promoter in cAC(s), which has A13′ and C14, not only reduced viral RNA replication in cells but also impaired de novo initiation of unprimed vRNA synthesis. Reverse genetics experiments confirmatively exhibited that this breakage in the cRNA promoter affected the rescue of infectious virus. The present study suggests that the first segment-specific base pair plays an essential role in generating infectious viruses by regulating the promoter activity of cRNA rather than vRNA. It could provide insights into the role of the segment-specific nucleotides in viral genome replication for sustainable infection.

description: Motivated by problems of mathematical physics (quantum chaos) questions of equidistribution of eigenfunctions of the Laplace operator on a Riemannian manifold have been studied by several authors. We consider here, in analogy with arithmetic hyperbolic surfaces, orthonormal bases of eigenfunctions of the Laplace operator on the two dimensional unit sphere which are also eigenfunctions of an algebra of Hecke operators which act on these spherical harmonics. We formulate an analogue of the equidistribution of mass conjecture for these eigenfunctions as well as of the conjecture that their moments tend to moments of the Gaussian as the eigenvalue increases. For such orthonormal bases we show that these conjectures are related to the analytic properties of degree eight arithmetic L-functions associated to triples of eigenfunctions. Moreover we establish the conjecture for the third moments and give a conditional (on standard analytic conjectures about these arithmetic L-functions) proof of the equdistribution of mass conjecture.

description: This study identifies differences of global timber models in its three different versions by comparing marginal abatement cost. The forest-only model has a relatively linear marginal cost curve; the other two models show concave cost curves, indicating that the marginal cost for carbon sequestration increases faster than in the forest-only model. Such basic differences among the models may be caused by the characteristics of the CET(Constant Elasticity of Transformation) model. The differences between the forest-only model and CET model are more narrowed when CET results are converted to physical units. This study contributes to the enhancement of the understanding of GTM development and provides foundation for future studies to improve global timber modeling.
Insight into the Heart Rate Variability of a Recovering Female High Jump Athlete

description: Background: High jump is a sport that requires a superior level of musculoskeletal and biomechanical function. Athletes perform a countermovement jump during the take-off phase whereby utilizing muscle spindle activation. This autonomic response has been examined for its interplay with the cardiac autonomic nervous system. Cardiac autonomic modulation, as derived using heart rate variability (HRV) remains a useful index for practitioners examining the dose-response to exercise. Purpose: This case-study examined the daily cardiac autonomic response of a university female high jump athlete who completed a novel exercise program in the effort to regain her health and performance. Methods: This study involved 115 consecutive days of data collection from the month of December to April. A resistance training and cardiorespiratory exercise program was provided to the participant that involved a significant reduction in training volume and exercise intensity. Results: Reductions in resistance training volume and cardiorespiratory exercise intensity over 80 consecutive days elicited improved cardiac autonomic function. When resorting back to a traditional track and field exercise regime during days 80-115, cardiac vagal activity significantly decreased. Conclusion: HRV can support track and field athletes as well as coaches through identifying alterations in cardiac autonomic function and its interplay with health and performance.

description: The Ly-$α$ forest 1D flux power spectrum is a powerful probe of several cosmological parameters. Assuming a $Λ$CDM cosmology including massive neutrinos, we find that the latest SDSS DR14 BOSS and eBOSS Ly-$α$ forest data is in very good agreement with current weak lensing constraints on $(Ω_m, σ_8)$ and has the same small level of tension with Planck. We did not identify a systematic effect in the data analysis that could explain this small tension, but we show that it can be reduced in extended cosmological models where the spectral index is not the same on the very different times and scales probed by CMB and Ly-$α$ data. A particular case is that of a $Λ$CDM model including a running of the spectral index on top of massive neutrinos. With combined Ly-$α$ and Planck data, we find a slight (3$σ$) preference for negative running, $α_s= -0.010 \pm 0.004$ (68% CL). Neutrino mass bounds are found to be robust against different assumptions. In the $Λ$CDM model with running, we find $\sum m_ν<0.11$ eV at the 95% confidence level for combined Ly-$α$ and Planck (temperature and polarisation) data, or $\sum m_ν< 0.09$ eV when adding CMB lensing and BAO data. We further provide strong and nearly model-independent bounds on the mass of thermal warm dark matter. For a conservative configuration consisting of SDSS data restricted to $z<4.5$ combined with XQ-100 \lya data, we find $m_X > 5.3\;\mathrm{keV}$ (95\%CL).

description: We introduce the flavor symmetry ${\bf Z}_M \times {\bf Z}_N \times D_4$ into the $SU(6) \times SU(2)_R$ string-inspired model. The cyclic group ${\bf Z}_M$ and the dihedral group $D_4$ are R symmetries, while ${\bf Z}_N$ is a non-R symmetry. By imposing the anomaly-free conditions on the model, we obtain a viable solution under many phenomenological constraints coming from the particle spectra. For neutrino sector, we find a LMA-MSW solution but not SMA-MSW ones. The solution includes phenomenologically acceptable results concerning fermion masses and mixings and also concerning hierarchical energy scales including the GUT scale, the $μ$ scale and the Majorana mass scale of R-handed neutrinos.
