Reconstruction of the standard model with classical conformal invariance in noncommutative geometry

description: In this paper, we derive the standard model with classical conformal invariance from the Yang--Mills--Higgs model in noncommutative geometry (NCG). In the ordinary context of the NCG, the {\it distance matrix} $M_{nm}$ which corresponds to the vacuum expectation value of Higgs fields is taken to be finite. However, since $M_{nm}$ is arbitrary in this formulation, we can take all $M_{nm}$ to be zero. In the original composite scheme, the Higgs field itself vanishes with the condition $M_{nm} = 0$. Then, we adopt the elemental scheme, in which the gauge and the Higgs bosons are regarded as elemental fields. By these assumptions, all scalars do not have vevs at tree level. The symmetry breaking mechanism will be implemented by the Coleman--Weinberg mechanism. As a result, we show a possibility to solve the hierarchy problem in the context of NCG. Unfortunately, the Coleman--Weinberg mechanism does not work in the SM Higgs sector, because the Coleman--Weinberg effective potential becomes unbounded from below for $m_{t} > m_{Z}$. However, viable models can be possible by proper extensions.

description: In a previous article, \cite{Zill3}, we have established linear inviscid damping for a large class of monotone shear flows in a finite periodic channel and have further shown that boundary effects asymptotically lead to the formation of singularities of derivatives of the solution. As the main results of this article, we provide a detailed description of the singularity formation and establish stability in all sub-critical fractional Sobolev spaces and blow-up in all super-critical spaces. Furthermore, we discuss the implications of the blow-up to the problem of nonlinear inviscid damping in a finite periodic channel, where high regularity would be essential to control nonlinear effects.

description: We investigate if the active galactic nucleus (AGN) of Mrk 590, whose supermassive black hole was until recently highly accreting, is turning off due to a lack of central gas to fuel it. We analyse new sub-arcsecond resolution ALMA maps of the $^{12}$CO(3-2) line and 344 GHz continuum emission in Mrk 590. We detect no $^{12}$CO(3-2) emission in the inner 150 pc, constraining the central molecular gas mass to $M({\rm H_2}) \lesssim 1.6 \times 10^5\, {M_{\odot}}$, no more than a typical giant molecular gas cloud, for a CO luminosity to gas mass conversion factor of $α_{\rm CO}\sim 0.8\,{M_{\odot}\,\rm (K \,km\,s^{-1}\,pc^{2}})^{-1}$. However, there is still potentially enough gas to fuel the black hole for another $2.6 \times 10^5$ years assuming Eddington-limited accretion. We therefore cannot rule out that the AGN may just be experiencing a temporary feeding break, and may turn on again in the near future. We discover a ring-like structure at a radius of $\sim 1$ kpc, where a gas clump exhibiting disturbed kinematics and located just $\sim 200$ pc west of the AGN, may be refueling the centre. Mrk 590 does not have significantly less gas than other nearby AGN host galaxies at kpc scales, confirming that gas reservoirs at these scales provide no direct indication of on-going AGN activity and accretion rates. Continuum emission detected in the central 150 pc likely originates from warm AGN-heated dust, although contributions from synchrotron and free-free emission cannot be ruled out.

With the strong field limit coefficient, three observable quantities are obtained, which are the innermost relativistic image, the deflection angle and the ratio of the flux. Comparing the observable value and the theoretical value of the strong gravitational lensing, we can verify the effectiveness of the strong gravitational lensing model.

Year: 2023
Subjects: Animal welfare; purchasing criteria; cross-national study; pork

description: Social acceptance of livestock farming has been declining in recent years. Especially the husbandry conditions of pigs are controversially discussed in society, industry and politics. We conducted an exploratory cross-national study (Poland, Italy, Japan and South Korea) to provide insights into consumer attitudes, preferences and possible willingness to pay for pork, considering the influence and importance of pork purchasing criteria, the country of origin and animal welfare. Five online focus groups took place in each study country and were analysed using a qualitative content analysis. Consumer knowledge of animal welfare differed in European and Asian countries, although it was limited overall. Regarding pork purchasing habits, all participants emphasized that freshness, appearance, quality, country of origin and price were important. Nevertheless, almost all participants linked higher animal welfare standards with higher meat quality and therefore saw a personal benefit. In all countries, there is a need to increase awareness on the subject of animal welfare by developing specific infomational campaigns.

Subjects: Trust; consumer expectations; organic food; focus groups

description: This paper addresses consumer trust in organic food in order to find out which aspects increase and decrease trust and which trust expectations consumers have. The aim is to strengthen consumer trust on the basis of the findings and to develop trust-building measures. To this end, ten focus groups with German consumers were conducted online in February 2021 and evaluated using content analysis. The results show that there is a predominant lack of trust in organic food. This is based in particular on the fact that organic production is often doubted and there are from the consumer’s point of view too many organic labels. This can be attributed not only to a lack of knowledge on the part of consumers, but also to a lack of transparency within the organic sector and in relation to organic food. Results from the consumer's point of view show that the possibility of control, information and transparency are relevant for trust in organic food and the development of knowledge about organic food can positively influence this trust.

Group Sparse Recovery via the $\ell^0(\ell^2)$ Penalty: Theory and Algorithm

description: In this work we propose and analyze a novel approach for group sparse recovery. It is based on regularized least squares with an $\ell^0(\ell^2)$ penalty, which penalizes the number of nonzero groups. One distinct feature of the approach is that it has the built-in decorrelation mechanism within each group, and thus can handle challenging strong inner-group correlation. We provide a complete analysis of the regularized model, e.g., existence of a global minimizer, invariance property, support recovery, and properties of block coordinatewise minimizers. Further, the regularized problem admits an efficient primal dual active set algorithm with a provable finite-step global convergence. At each iteration, it involves solving a least-squares problem on the active set only, and exhibits a fast local convergence, which makes the method extremely efficient for recovering group sparse signals. Extensive numerical experiments are presented to illustrate salient features of the model and the efficiency and accuracy of the algorithm. A comparative study indicates its competitiveness with existing approaches.

The relationship directly affects the dependence between Arabica and Robusta coffees commodities. While the relationship between wheat, Arabica and Robusta coffees, and soybean is positively dependent. Economic growth, market dynamics, and the prices of an agricultural commodity tend to increase the price of other commodities.

description: The search for new quantum spin Hall (QSH) phase and effective manipulations of their edge states are very important for both fundamental sciences and practical applications. Here, we use first-principles calculations to study the strain-driven topological phase transition of two-dimensional (2D) arsenene monolayer. We find that the band gap of arsenene decreases with increasing strain and changes from indirect to direct, and then the s-p band inversion takes place at Γ point as the tensile strain is larger than 11.14%, which lead to a nontrivially topological state. A single pair of topologically protected helical edge states is established for the edge of arsenene, and their QSH states are confirmed with nontrivial topological invariant Z2 = 1. We also propose high-dielectric BN as an ideal substrate for the experimental synthesis of arsenene, maintaining its nontrivial topology. These findings provide a promising candidate platform for topological phenomena and new quantum devices operating at nanoelectronics.

description: The Circular Electron Positron Collider (CEPC) is a future Higgs factory proposed by the Chinese high energy physics community. It will operate at a center-of-mass energy of 240-250 GeV. The CEPC will accumulate an integrated luminosity of 5 ab$^{\rm{-1}}$ in ten years' operation, producing one million Higgs bosons via the Higgsstrahlung and vector boson fusion processes. This sample allows a percent or even sub-percent level determination of the Higgs boson couplings. With GEANT4-based full simulation and dedicated fast simulation tool, we evaluated the statistical precisions of the Higgstrahlung cross section $σ_{ZH}$ and the Higgs mass $m_{H}$ measurement at the CEPC in the $Z\rightarrowμ^+μ^-$ channel. The statistical precision of $σ_{ZH}$ ($m_{H}$) measurement could reach 0.97\% (6.9 MeV) in the model-independent analysis which uses only the information of Z boson decay. For the standard model Higgs boson, the $m_{H}$ precision could be improved to 5.4 MeV by including the information of Higgs decays. Impact of the TPC size to these measurements is investigated. In addition, we studied the prospect of measuring the Higgs boson decaying into invisible final states at the CEPC. With the standard model $ZH$ production rate, the upper limit of ${\cal B}(H\rightarrow \rm{inv.})$ could reach 1.2\% at 95\% confidence level.

description: Research on the design of the perishable food supply chain network has increased in recent years. However, little attention has been given to those seasonal foods that generate periods of oversupply and, particularly, to their impact on the sustainability of small producers in developing countries. This research proposes and develops a multi-objective mixed linear programming model for perishable fruits in a south American country at oversupply periods. It minimizes losses and transportation costs and maximizes the inclusion of farmers. It considers four echelons of the supply chain: farms, collection centers, distribution centers and the demand, which is represented by the agroindustry, wholesalers, shopkeepers, and hypermarkets. The Epsilon constraint method is used to solve the multi-objective model. A set of Pareto optimal solutions helped evaluate tradeoffs between the three objectives and find the location of collection and distribution centers. The proposed generic mathematical model is applicable to any food supply chain, as it allows for the improvement of the established performance measures and the distribution flows for the different echelons. The model considers the losses in perishable food from the impacts caused by changes in temperature (T0) and humidity level (RH) at different thermal floors of mountain ranges.

description: We investigate the deceleration of Solar Energetic Particles (SEPs) during their propagation from the Sun through interplanetary space, in the presence of weak to strong scattering in a Parker spiral configuration, using relativistic full orbit test particle simulations. The calculations retain all three spatial variables describing particles' trajectories, allowing to model any transport across the magnetic field. Large energy change is shown to occur for protons, due to the combined effect of standard adiabatic deceleration and a significant contribution from particle drift in the direction opposite to that of the solar wind electric field. The latter drift-induced deceleration is found to have a stronger effect for SEP energies than for galactic cosmic rays. The kinetic energy of protons injected at 1 MeV is found to be reduced by between 35 and 90% after four days, and for protons injected at 100 MeV by between 20 and 55%. The overall degree of deceleration is a weak function of the scattering mean free path, showing that, although adiabatic deceleration plays a role, a large contribution is due to particle drift. Current SEP transport models are found to account for drift-induced deceleration in an approximate way and their accuracy will need to be assessed in future work.

description: Besides damage to the environment, current industrial agriculture has decreased ecosystem capacity and provided the context for spreading various diseases in human communities. The covid-19 crisis and traffic restrictions not only had a hygienic, economical, and social impact but also caused disruptions in the food supply chain and the fragility of food systems in some regions asynchronously. Theoretically and practically, agriculture and food supply chain paradigm-shifting using the Internet of things (IoT) and Agroecology paradigm application, by providing food security, shortening the food supply chain, and improving food security, is considered a proper response to COVID-19 shock.

description: High-energy Li-Be-B nuclei in cosmic rays are being measured with unprecedent accuracy by the AMS experiment. These data bring valuable information to the cosmic ray propagation physics. In particular, combined measurements of B/C and Be/B ratios may allow to break the parameter degeneracy between the cosmic-ray diffusion coefficient and the size of the propagation region, which is crucial for dark matter searches. The parameter determination relies in the calculation of the Be and B production from collisions of heavier nuclei with the gas. Using the available cross-section data, I present for the first time an evaluation of the nuclear uncertainties and their impact in constraining the propagation models. I found that the AMS experiment can provide tight constraints on the transport parameters allowing to resolutely break the degeneracy, while nuclear uncertainties in the models are found to be a major limiting factor. Once these uncertainties are accounted, the degeneracy remains poorly resolved. In particular, the Be/B ratio at ~1 - 10 GeV/n is found not to bring valuable information for the parameter extraction. On the other hand, precise Be/B data at higher energy may be useful to test the nuclear physics inputs of the models.

description: This paper describes a questionnaire survey on Visual Literacy (VL) in archives.  The study examined claims that VL should be an area of concern for archivists who are working increasingly with images as a result of the saturation of images in society.  Research questions addressed included: Do archivists tend to have any previous training in VL related skills? Do archivists think that the skills identified by the VL index apply well to their work?  How do archivists perceive their own VL?  Results suggest that many archivists have little training in VL related skills, that the skills identified by the VL index tend to apply to their work, and that they view their own VL skills in a generally positive manner, but would support additional training.

Research and Development of Commercially Manufactured Large GEM Foils

description: With future experiments proposing detectors that utilize very large-area GEM foils, there is a need for commercially available GEM foils. Double-mask etching techniques pose a clear limitation in the maximum size of GEM foils. In contrast, single-mask techniques developed at CERN would allow one to overcome those limitations. However with interest in GEM foils increasing and CERN being the only main distributor, keeping up with the demand for GEM foils will be difficult. Thus the commercialization of GEMs has been established by Tech-Etch of Plymouth, MA, USA using single-mask techniques. We report on the electrical and geometrical properties, along with the inner and outer hole diameter size uniformity of 10 $\times$ 10 cm$^2$ and 40$\times$40 cm$^2$ GEM foils. The Tech-Etch foils were found to have excellent electrical properties. The measured mean optical properties were found to reflect the desired parameters and are consistent with those measured in double-mask GEM foils, and show good hole diameter uniformity over the active area. These foils are well suited for future applications in nuclear and particle physics where tracking devices are needed.

description: Purpose: This study investigated the effectiveness of the stuttering modification intervention Kinder Dürfen Stottern (KIDS) in school-age children who stutter. Method: Seventy-three children who stutter were included in this multicenter, two-group parallel, randomized, wait-list controlled trial with a follow-up of 12 months. Children aged 7–11 years were recruited from 34 centers for speech therapy and randomized to either the immediate-treatment group or the 3 months delayed-treatment group. KIDS was provided by 26 clinicians who followed a treatment manual. Although the primary outcome measure was the impact of stuttering (Overall Assessment of the Speaker’s Experience of Stuttering–School-Age [OASES-S]), the secondary outcomes included objective and subjective data on stuttering severity. Results: At 3 months postrandomization, the mean score changes of the OASES-S differed significantly between the experimental (n = 33) and control group (n = 29; p = .026). Furthermore, treatment outcomes up to 12 months were analyzed (n = 59), indicating large effects of time on the OASES-S score (p < .001, partial η2 = .324). This was paralleled by significant improvements in parental ratings and objective ratings (stuttering severity, frequency, and physical concomitants). Conclusions: The significant short-term treatment effects in the OASES-S are in line with the (initial) focus of KIDS on cognitive and affective aspects of stuttering. Over 12 months, these changes were maintained and accompanied by behavioral improvements. The results suggest that individual treatment with KIDS is an adequate treatment option for this age group.

title: Spiking efficiency of electrically stimulated pyramidal cells: a modeling study

description: During electrical stimulation of the pyramidal cell (PC), the spiking efficiency increases from 0 to 1 at the lower threshold and decreases from 1 to 0 at the upper threshold as the stimulus amplitude increases. Spiking efficiency as a function of stimulus amplitude follows a sigmoidal or reverse sigmoidal shape, respectively.Many modeling studies examine the threshold and origin of spike i.e., action potential (AP) initiation in PCs in relation to different positions and configurations of the stimulation electrode using deterministic models in which the spiking efficiency as a function of the stimulus amplitude reduces to the step function. Fewer studies deal with modeling that includes a stochastic component in the model. Here, this was achieved by injecting a maximum-sodium-conductance-dependent noise current into each compartment with an active membrane. The spiking efficiency was examined in relation to different positions and configurations of the stimulation electrode, where the threshold and origin of AP initiation were observed, and the geometric and electrophysiological properties of the model were changed. Dynamic range (DR) and relative spread (RS) were used to measure the increase in spiking efficiency with a stimulus intensity. A simplified geometry of the PC was used, with two basic electrophysiological configurations. The first is a standard model that contains three voltage gated active channels: high-threshold 〖Na〗_v 1.2 and low-threshold 〖Na〗_v 1.6 sodium and fast K_v potassium channels. The second is an extended model that additionally contains two potassium channels, slow non-inactivating potassium current K_m and calcium dependent K_Ca, then high-voltage activated 〖Ca〗_v channel and internal calcium concentration mechanism 〖Ca〗_cm.The following can be concluded from the simulation experiments in this thesis. In general, a larger DR is expected by stimulating more excitable parts of the PC, with a few exceptions. It seems that when stimulating highly excitable parts of the PC, there is a competition between responsiveness and noisiness, which can reduce DR. DR is the largest between the unmyelinated axon and the first node of Ranvier, and the smallest at the dendrite. In addition to the geometric and electrophysiological properties of the cell, the activating function and the origin of AP initiation should also be considered for the prediction of DR. Additional channels in the extended model have almost no effect on the threshold, and a slightly larger, but still small, effect on the DR.
