description: In this work we study genuine multipartite correlations (GMC's) in a boundary time crystal (BTC). Boundary time crystals are nonequilibrium quantum phases of matter in contact to an environment, for which a macroscopic fraction of the many-body system breaks the time-translation symmetry. We analyze both (i) the structure (orders) of GMC's among the subsystems, as well as (ii) their build-up dynamics for an initially uncorrelated state. We find that, in the thermodynamic limit (and only in such a limit), multipartite correlations of all orders grow indefinitely in time in the BTC phase, further displaying a persistent oscillatory behavior around their mean growth. The orders of the correlations show a power-law decaying hierarchy among its $k$-partitions. Moreover, in the long-time limit the GMC's are shown extensive with the system size, contrasting to the subextensive scaling in the non time-crystal (ferromagnetic) phase of the model. We also discuss the classical and quantum nature of these correlations with basis on multipartite entanglement witnesses, specifically, the analysis of the Quantum Fisher Information (QFI). Both GMC and QFI are able to capture and distinguish the different phases of the model. Our work highlights the genuine many-body properties of these peculiar non-equilibrium phases of matter.

description: Using new experimental data on photoproduction and $Λ_b^0$ decays, we derive constraints on the properties of the LHCb $P_c$ states. We conclude that $P_c(4312)$, $P_c(4380)$ and $P_c(4440)$ can be described as $Σ_c\bar D$, $Σ_c^*\bar D$ and $Σ_c\bar D^*$ molecules, but that $P_c(4457)$ does not fit into the same picture. Based on the apparent absence of additional partner states, and the striking disparity between $Λ_c^+\bar D^0$ and $Λ_c^+\bar D^{*0}$ decays, we conclude that $P_c(4440)$ has $3/2^-$ quantum numbers. Using heavy-quark symmetry we predict large experimental signals for $P_c$ states in $η_c p K^-$, $Λ_c^+\bar D^{*0}K^-$, and $Σ_c^{(*)}\bar D K^-$. We also argue that current experimental data on photoproduction is almost at the level of sensitivity required to observe $P_c$ states.

description: In this work, conserved charges and fluxes at the future null infinity are determined in the asymptotically flat spacetime for Chern-Simons modified gravity. The flux-balance laws are used to constrain the memory effects. For tensor memories, the Penrose's conformal completion method is used to analyze the asymptotic structures and asymptotic symmetries, and then, conserved charges for the Bondi-Metzner-Sachs algebra are constructed with the Wald-Zoupas formalism. These charges take very similar forms to those in Brans-Dicke theory. For the scalar memory, Chern-Simons modified gravity is rewritten in the first-order formalism, and the scalar field is replaced by a 2-form field dual to it. With this dual formalism, the scalar memory is described by the vacuum transition induced by the large gauge transformation of the 2-form field.

description: L’articolo presenta alcuni casi di studio sulla produzione di musica per film di Vassil Kojucharov – compositore attivo negli ambienti del film popolare e di genere tra la fine degli anni Sessanta e i primi Settanta –, sulla base dei documenti conservati presso l’associazione Nomus di Milano. Lo studio di queste fonti è inquadrato all’interno del concetto di modularità, inteso tanto come principio strutturale per interpretare lo sviluppo formale della musica nella cinematografia di genere, quanto come framework concettuale più ampio per affrontare gli oggetti della popular culture, nel loro intreccio tra istanze estetiche, produttive e comunicative. Nell’esplorazione di questo complesso di fonti sulla produzione cinematografica di questo compositore, un approccio modulare si rivela un potente strumento analitico e metodologico per la comprensione dei processi tipici della produzione dei prodotti popolari a basso costo, oltre a suggerire indicazioni per l’organizzazione e la schedatura del Fondo Kojucharov stesso.

description: This umbrella review aimed at assessing whether a protein intake exceeding the current recommendation for younger (0.8 g/kg body weight [BW]/day) and older (1.0 g/kg BW/day) adults affects bone mineral density and fracture risk. Moreover, the effect of animal or plant protein was evaluated. A systematic literature search was conducted in PubMed, Embase, and Cochrane Database of Systematic Reviews for systematic reviews (SRs) with or without meta-analysis of prospective studies published between 11/2008 and 08/2021. Methodological quality, outcome-specific certainty of evidence, and overall certainty of evidence of the retrieved SRs were assessed using established tools and predefined criteria. Eleven SRs of randomized controlled trials (RCTs) and/or cohort studies were included. In SRs of cohort studies and RCTs, protein intake/kg BW/day ranged between 0.21–0.95 g (low intake) and > 1.24 g (high intake), respectively, and between 0.67–1.1 g (control groups) and 1.01–1.69 g (intervention groups), respectively. The vast majority of outcome-specific certainty of evidence was rated “low” or “very low.” The overall certainty of evidence for an association (cohort studies) or effect (RCTs) of total, animal or plant protein intake on each of the investigated outcomes was rated “insufficient,” with the exception of possible evidence for a reduced hip fracture risk by high vs. low protein intake. Since protein intakes in low/control and high/intervention groups were very heterogeneous and with low certainty of evidence, it remains unclear whether a dose above the current recommendation or type of protein intake (animal or plant protein) affects bone health overall. However, there is possible evidence for reduced hip fracture risk with high versus low protein intake.

description: In this work we present a derivation of the real-time time-dependent orbital-optimized Møller-Plesser TDOMP2 and its biorthogonal companion, time-dependent non-orthogonal OMP2 (TDNOMP2), theory starting from the time-dependent bivariational principle and a parametrization based on the exponential orbital-rotation operator formulation commonly used in time-independent molecular electronic-structure theory. We apply the TDOMP2 method to extract absorption spectra and frequency-dependent polarizabilities and first hyperpolarizabilities from real-time simulations, comparing the results with those obtained from conventional time-dependent coupled-cluster singles and doubles (TDCCSD) simulations and from its second-order approximation TDCC2. We also compare with results from CCSD and CC2 linear and quadratic response theory. Our results indicate that while TDOMP2 absorption spectra are of the same quality as TDCC2 spectra, frequency-dependent polarizabilities and hyperpolarizabilties from TDOMP2 simulations are significantly closer to TDCCSD results than those from TDCC2 simulations.

description: Background: Several studies demonstrated a considerable complication rate for open ankle or TTC arthrodesis in patients with diabetes, revision surgery and ulceration. Extensive approaches in combination with multimorbide patients have been suggested as the rationale behind the increased complication rate. Methods: Single-centre, prospective case-control study compared arthroscopic vs. open ankle arthrodesis in patients with Charcot Neuro-Arthropathy of the foot. 18 patients with septic Charcot Neuro-Arthropathy Sanders III–IV received an arthroscopic ankle arthrodesis with TSF (Taylor Spatial Frame®) fixation combined with different additional procedures required for infect treatment and hindfoot realignment. The ankle arthrodesis was required for the realignment of the hindfoot in Sanders IV patients, arthritis or in case of infection. 12 patients were treated with open ankle arthrodesis and TSF fixation combined with various additional procedures. Results: A significant improvement has been shown in radiological data in both groups. A significant lower complication rate has been registered in arthroscopic group. A significant correlation was seen between major complications and therapeutic anticoagulation as well as smoking. Conclusion: In high-risk patients with diabetes and plantar ulceration excellent results could be demonstrated in arthroscopically performed ankle arthrodesis with midfoot osteotomy using TSF as fixation devise.

description: We explore the interplay of disorder and topological phenomena in honeycomb lattices of atoms coupled by the electromagnetic field. On the one hand, disorder can trigger transitions between distinct topological phases and drive the lattice into the topological Anderson insulator state. On the other hand, the nontrivial topology of the photonic band structure suppresses Anderson localization of modes that disorder introduces inside the band gap of the ideal lattice. Furthermore, we discover that disorder can both open a topological pseudogap in the spectrum of an otherwise topologically trivial system and introduce spatially localized modes inside it.

description: This paper summarizes the results obtained from an international comparison exercise on neutron spectra unfolding in Bonner spheres spectrometry, organized within the activities of EURADOS working group 6: computational dosimetry. Four realistic situations were considered: a medical accelerator, a workplace field, an irradiation room and a skyshine scenario. The reference solutions are presented, given in terms of idealized fluence-energy distributions and dose rates, along with details of their derivation using verified Monte Carlo codes. The wide variety of unfolded results that were submitted by the participants are then provided, with some shown to agree well with the reference solutions but others showing significant energy-dependent discrepancies. Finally, explanations for some of these discrepancies are proposed, along with suggested methods for how they might be improved.

description: Some time ago, we reported the synthesis of bixbyite-type V2O3, a new metastable polymorph of vanadium sesquioxide. Since, a number of investigations followed, dealing with different aspects like electronic and magnetic properties of the material, the deviation from ideal stoichiometry or the preparation of nanocrystals as oxygen storage material. However, most of the physical properties were only evaluated on a theoretical basis. Here, we report the lattice dynamics and physical properties of bixbyite-type V2O3 bulk material, which we acquired from physical property measurements and neutron diffraction experiments over a wide temperature range. Besides attributing different possible orientations of the magnetic moments for V1 and V2 to the identified antiferromagnetic (AFM) ground state with a Néel temperature of 38.1(5) K, we use a first order Grüneisen approximation to determine lattice-dependent parameters for the relatively stiff cubic lattice, and, amongst others identify the Debye temperature to be as low as 350 ± 65 K.

description: Studierende naturwissenschaftlicher Fächer sollen innerhalb ihrer Lehreramtsausbildung nicht nur Kompetenzen im Experimentieren entwickeln, sondern auch lernen, ihre Fähigkeiten und Fertigkeiten im Experimentieren professionell einzuschätzen. Die Einschätzung eigener Experimentierfähigkeiten wird als experimentbezogenes Fähigkeitsselbstkonzept bezeichnet. Dieses kann theoretisch in die Dimensionen Planung, Durchführung und Auswertung von Experimenten separiert werden. Ein positives experimentbezogenes Fähigkeitsselbstkonzept kann in einer hohen Bereitschaft, Experimentalunterricht zu planen, durchzuführen und zu reflektieren, münden. Dies wird bereits dann bedeutsam, wenn Studierende in schulische Praxisphasen, wie das Praxissemester, eintreten. Forschungsbefunde zum experimentbezogenen Fähigkeitsselbstkonzept von Studierenden sind jedoch noch unzureichend. Um diesem Forschungsdesiderat zu begegnen, wurden innerhalb einer Querschnittsstudie die experimentbezogenen Fähigkeitsselbstkonzepte von 200 Studierenden der Fächer Biologie, Chemie und Sachunterricht mittels Fragebögen untersucht. Eine Erhebung im Fach Physik steht noch aus. Die faktorielle Struktur des experimentbezogenen Fähigkeitsselbstkonzepts und die Ausprägungen des experimentbezogenen Fähigkeitsselbstkonzepts der Studierenden wurden ermittelt. Die Ergebnisse zeigen, dass das experimentbezogene Fähigkeitsselbstkonzept auch empirisch in die Dimensionen Planung, Durchführung und Auswertung unterteilt werden kann. Die höchsten experimentbezogenen Fähigkeitsselbstkonzepte haben die Studierenden im Bereich der Durchführung. Signifikante Unterschiede zwischen den Fächergruppen zeigen sich im Bereich der Auswertung von Experimenten.

description: Digital twins (DTs) are an emerging phenomenon in the public and private sectors as a new tool to monitor and understand systems and processes. DTs have the potential to change the status quo in ecology as part of its digital transformation. However, it is important to avoid misguided developments by managing expectations about DTs. We stress that DTs are not just big models of everything, containing big data and machine learning. Rather, the strength of DTs is in combining data, models, and domain knowledge, and their continuous alignment with the real world. We suggest that researchers and stakeholders exercise caution in DT development, keeping in mind that many of the strengths and challenges of computational modelling in ecology also apply to DTs.

description: In this work, we have studied some bouncing cosmologies in the frame work of $f(R,T)$ gravity. The bouncing scenario has been formulated to avoid the big bang singularity. The physical and geometrical parameters are investigated. The effect of the extended gravity theory on the dynamical parameters of the model is investigated. It is found that, the $f(R,T)$ gravity parameter affects the cosmic dynamics substantially. We have also, tested the model through the calculation of the cosmographic coefficients and the $Om(z)$ parameter. A scalar field reconstruction of the bouncing scenario is also carried out. The stability of the model are tested under linear, homogeneous and isotropic perturbations.

description: Methodologies for characterization of the lateral indentation of silicon-germanium (SiGe) nanosheets using different non-destructive and in-line compatible metrology techniques are presented and discussed. Gate-all-around nanosheet device structures with a total of three sacrificial SiGe sheets were fabricated and different etch process conditions used to induce indent depth variations. Scatterometry with spectral interferometry and x-ray fluorescence in conjunction with advanced interpretation and machine learning algorithms were used to quantify the SiGe indentation. Solutions for two approaches, average indent (represented by a single parameter) as well as sheet-specific indent, are presented. Both scatterometry with spectral interferometry as well as x-ray fluorescence measurements are suitable techniques to quantify the average indent through a single parameter. Furthermore, machine learning algorithms enable a fast solution path by combining x-ray fluorescence difference data with scatterometry spectra, therefore avoiding the need for a full optical model solution. A similar machine learning model approach can be employed for sheet-specific indent monitoring; however, reference data from cross-section transmission electron microscopy image analyses are required for training. It was found that scatterometry with spectral interferometry spectra and a traditional optical model in combination with advanced algorithms can achieve a very good match to sheet-specific reference data.

description: We introduce a large and diverse Czech corpus annotated for grammatical error correction (GEC) with the aim to contribute to the still scarce data resources in this domain for languages other than English. The Grammar Error Correction Corpus for Czech (GECCC) offers a variety of four domains, covering error distributions ranging from high error density essays written by non-native speakers, to website texts, where errors are expected to be much less common. We compare several Czech GEC systems, including several Transformer-based ones, setting a strong baseline to future research. Finally, we meta-evaluate common GEC metrics against human judgements on our data. We make the new Czech GEC corpus publicly available under the CC BY-SA 4.0 license at http://hdl.handle.net/11234/1-4639 .

description: The dynamical similarity which exists between the $λ$-mode excited $bbq$ baryons ($q$ refers to the $u$, $d$, and $s$ quarks) and the $\bar{b}q$ mesons inspires us to carry out a combined study of their spectroscopy. In this work, the masses and strong decays of these low-lying $b\bar{q}$ and $bbq$ states are studied by the same theoretical methods, and the dynamical similarity which is implied in their mass spectra and strong decays are also discussed. The recent discovered $\bar{b}q$ states, including the $B_J(5840)$, $B_J(5970)$, $B_{sJ}(6064)$, and $B_{sJ}(6114)$, are analyzed. According to our result, the $B_J(5840)$ could be assigned as a 2$S$ state, while the $B_J(5970)$ could be regarded as a member of the $1D(2^-,~3^-)_{j_q=5/2}$ doublet. The $B_{sJ}(6064)$ and $B_{sJ}(6114)$ are probably the $D$-wave states. Especially, they could be explained as the members of the $1D(1^-,~2^-)_{j_q=3/2}$ and $1D(2^-,~3^-)_{j_q=5/2}$ doublets, respectively. The predicted masses and decay properties of other unknown $\bar{b}q/bbq$ states may provide useful clues to the future experiment.

description: Background: Hidradenitis suppurativa (HS) is an inflammatory disease of the inverse skin regions that occurs in young women, in particular, and affects approximately 1% of the population. Outpatient care is often inadequate and usually cannot prevent progression. Objectives: To evaluate in the EsmAiL (‘Evaluation eines strukturierten und leitlinienbasierten multmodalen Versorgungskonzepts für Menschen mit Akne inversa’) trial whether an innovative care concept can decrease disease activity and burden, and improve patient satisfaction. Methods: EsmAiL was conducted as a two-arm, multicentre, prospective, randomized controlled trial that included 553 adults with HS. Inclusion criteria were a minimum of three inflammatory lesions and at least a moderate impact of the disease on quality of life. The control group (CG) remained under standard care, while patients in the intervention group (IG) were treated according to a trial-specific, multimodal concept. The primary endpoint was the absolute change in International Hidradenitis Suppurativa Severity Score System (IHS4). Results: In total, 274 patients were randomized to the IG and 279 to the CG. Altogether, 377 attended the final assessment after 12 months of intervention. Participants in the IG (n = 203) achieved a mean improvement in IHS4 of 9.3 points, while the average decrease in IHS4 in patients in the CG (n = 174) was 5.7 points (P = 0.003). Patients treated under the new care concept also reported a statistically significantly higher decrease in pain, Dermatology Life Quality Index and Hospital Anxiety and Depression Scale scores compared with those in the CG (P < 0.001). Patient satisfaction was also statistically significantly higher in the IG compared with the CG (P < 0.001). Conclusions: The establishment of standardized treatment algorithms in so-called ‘acne inversa centres’ in the ambulatory setting has a substantial, positive impact on the course of HS and significantly improves patient satisfaction.
Moiré Landau levels of a $C_4$-symmetric twisted bilayer system in the absence of a magnetic field

description: It is widely known that the twisted bilayer graphene (TBG) shows flat bands at magic angles, which can be well described by the effective continuum model derived by Bistritzer and MacDonald (BM). We propose in this paper a similar twisted bilayer system but defined on the square lattice with $π$-flux per plaquette, and study its spectrum using the BM Hamiltonian with a mass term which is originated from the staggered potential. The basic difference between the TBG and the present model is simply rotational symmetry, $C_3$ vs $C_4$, as well as a mass term. Nevertheless, the feature of the flat bands is quite different: Those of the TBG appear at magic angles only, while the present model shows many flat bands, which are reminiscent of Landau levels, quite stably at any angles even in the absence of a magnetic field other than $π$-flux which keeps time reversal (TR) symmetry. Moreover, flat bands emerge in the mass gap of the Dirac spectrum, and each state composing these flat bands is well-localized at the position forming the moiré lattice. It turns out that the moiré potential serves as a periodic magnetic field, which can give energies smaller that the gap around moiré lattice positions. We derive a local Hamiltonian valid around the moiré lattice sites and show that it indeed reproduces the energies of the flat bands within the mass gap. Since these mid-gap states are localized at the moiré lattice, they form degenerate levels, which may be referred to as moiré Landau levels, although the mechanism of degeneracies are different from the conventional Landau levels. Interestingly, doubled fermions of the BH Hamiltonian associated with two layers have opposite charges when they couple with the effective moiré magnetic filed, which concern TR symmetry.

description: Previous simulation studies on human connectomes suggested, that critical dynamics emerge subcrititcally in the so called Griffiths Phases. %This is the consequence of the strong heterogeneity of the graphs. Now we investigate this on the largest available brain network, the $21.662$ node fruit-fly connectome, using the Kuramoto synchronization model. As this graph is less heterogeneous, lacking modular structure and exhibit high topological dimension, we expect a difference from the previous results. Indeed, the synchronization transition is mean-field like, and the width of the transition region is larger than in random graphs, but much smaller than as for the KKI-18 human connectome. This demonstrates the effect of modular structure and dimension on the dynamics, providing a basis for better understanding the complex critical dynamics of humans.

description: Will man Lehrkräfte systematisch dabei unterstützen, digitale Medien lernförderlich im Unterricht einzusetzen, benötigt man ein Modell medienbezogener Kompetenzen von Lehrkräften. Der vorliegende Beitrag stellt das Rahmenmodell „Kernkompetenzen von Lehrkräften für das Unterrichten in einer digitalisierten Welt“ (DCB, 2017) vor, welches sich im Vergleich zu anderen Ansätzen zur Systematisierung und Operationalisierung medienbezogener Kompetenzen von Lehrkräften dadurch auszeichnet, dass es besonders klar auf die konkreten medienbezogenen Handlungskompetenzen von (angehenden) Lehrkräfte im schulischen Unterricht Bezug nimmt und auf die Anregung von qualitätsvollen schülerseitigen Lernaktivitäten mit digitalen Medien eingeht. Am Beispiel eines konkreten Szenarios aus dem Biologieunterricht zum Thema „Die Honigbiene im Kontext des Klimawandels und der Temperaturregulation“ wird aufgezeigt, wie das Modell der Kernkompetenzen produktiv dazu verwendet werden kann, die für einen erfolgreichen medienbasierten Unterricht erforderlichen Wissensbereiche und Handlungskompetenzen von (angehenden) Lehrkräften zu identifizieren. Damit wird ein Beitrag geleistet zur systematischen Beschreibung medienbasierter Unterrichtsszenarien unter dem Gesichtspunkt der Qualität des Einsatzes digitaler Medien sowie der hierfür erforderlichen medienbezogenen Wissensarten und Handlungskompetenzen von (angehenden) Lehrkräften.

description: We report a detailed study of superconductivity in polycrystalline SnTaS$_2$ using electrical transport, magnetization and heat capacity measurements. SnTaS$_2$ crystallizes in centrosymmetric hexagonal structure with space group $P6_3/mmc$. Electrical resistivity, magnetization and specific heat data suggest SnTaS$_2$ to be a weakly coupled, type-II superconductor with $T_c \approx$ 2.8 K. First-principles calculations show signature for nodal line topology in the electronic band structure, protected by the spatial-inversion and time-reversal symmetries, that strongly gapped out by the inclusion of spin-orbit coupling (SOC). Superconductivity in layered SnTaS$_2$ with nodal line topological state makes it a strong candidate to be considered for a 3D topological superconductor.

description: Recent academic literature has suggested that design thinking training has a positive impact on dynamic managerial capabilities that are vital for firm performance. However, it is yet not clear how these effects are realized. We suggest that the positive impact of design think-ing training on dynamic managerial capabilities can be attributed to changes in two aspects of managerial cognition: creative problem solving as a mental process and creative self- efficacy as a psychological belief. We test our hypotheses in a quasi- experimental pretest– posttest field study in the aviation industry among 100 mid- and lower- level managers and a 5- month time lag. The intervention is a 2- day design thinking training based on experiential learning. We find that design thinking training realizes its effects on dynamic managerial capabilities rather indirectly through creative problem solving and creative self- efficacy. Our study provides a more nuanced understanding of the relationship between design thinking and dynamic managerial capabilities and showcases the role changes in manage-rial cognition play in the dynamic capability development of mid- and lower- level manag-ers. Furthermore, it contributes to the scarce empirical research on the effects of design thinking on individual- level effects. For practitioners, our research shows how organiza-tions can benefit from design thinking training by boosting their managers abilities to spot and take advantage of new business opportunities.

description: Recently in Ref.\cite{Wen:2021qgx}, one of the authors introduced the balanced partial entanglement (BPE), which has been proposed to be dual to the entanglement wedge cross-section (EWCS). In this paper, we explicitly demonstrate that the BPE could be considered as a proper measure of the total intrinsic correlation between two subsystems in a mixed state. The total correlation includes certain crossing correlations which are minimized on some balance conditions. By constructing a class of purifications from Euclidean path-integrals, we find that the balanced crossing correlations show universality and can be considered as the generalization of the Markov gap for canonical purification. We also test the relation between the BPE and the EWCS in three-dimensional asymptotically flat holography. We find that the balanced crossing correlation vanishes for the field theory invariant under BMS$_3$ symmetry (BMSFT) and dual to the Einstein gravity, indicating the possibility of a perfect Markov recovery. We further elucidate these crossing correlations as a signature of tripartite entanglement and explain their interpretation in both AdS and non-AdS holography.

description: We investigate the spectral topology of one-dimensional lattices where the nonreciprocal hoppings within the nearest $r_d$ neighboring sites are the same. For the purely off-diagonal model without onsite potentials, the energy spectrum of the lattice under periodic boundary conditions (PBCs) forms an inseparable loop that intertwines with itself in the complex energy plane and is characterized by winding numbers ranging from 1 up to $r_d$. The corresponding spectrum under open boundary conditions (OBCs), which is real in the nearest neighboring model, will ramify and take the shape of an $(r_d+1)$-pointed star with all the branches connected at zero energy. If we further introduce periodic onsite modulations, the spectrum will gradually divide into multiple separable bands as we vary the parameters. Most importantly, we find that a different kind of band gap called loop gap can exist in the PBC spectrum, separating an inner loop from an outer one with each composed by part of the spectrum. In addition, loop structures also exist in the OBC spectra of systems with onsite potentials. We further study the lattices with power-law decaying long-range nonreciprocal hopping and found that the intertwined loops in the PBC spectrum will be untangled. Finally, we propose an experimental scheme to realize the long-range nonreciprocal models by exploiting electrical circuits. Our work unveils the exotic spectral topology in the long-range nonreciprocal lattices.

description: We develop a mathematical model for transferring the vaccine BNT162b2 based on the heat diffusion equation. Then, we apply optimal control theory to the proposed generalized SEIR model. We introduce vaccination for the susceptible population to control the spread of the COVID-19 epidemic. For this, we use the Pontryagin minimum principle to find the necessary optimality conditions for the optimal control. The optimal control problem and the heat diffusion equation are solved numerically. Finally, several simulations are done to study and predict the spread of the COVID-19 epidemic in Italy. In particular, we compare the model in the presence and absence of vaccination.

description: A recent ERS analysis estimated the potential range of the Government’s cost for the Agriculture Risk Coverage (ARC) and Price Loss Coverage (PLC) programs over the next 10 years for the three largest covered commodities—corn, soybeans, and wheat. Simulating program costs at both the county and national levels indicates program expenditures could vary widely due to uncertainty in commodity markets.

description: We study the stellar mass-to-halo mass relation at $z=0$ in 30 Milky Way-like systems down to the ultra-faint ($M_* < 10^5 M_\odot$) regime using the semi-analytic model A-SLOTH. A new model allows us to follow star formation and the stochastic stellar feedback from individually sampled Pop II stars. Our fiducial model produces consistent results with the stellar mass-to-halo mass relation derived from abundance matching and the observed cumulative stellar mass function above the observational completeness. We find a plateau in the stellar mass-to-halo mass relation in the ultra-faint regime. The stellar mass of this plateau tells us how many stars formed before supernovae occur and regulate further star formation, which is determined by the Pop~II star formation efficiency. We also find that the number of luminous satellites increases rapidly as $M_*$ decreases until $M_* \approx 10^4 M_\odot$. Finally, we find that the relative streaming velocity between baryons and dark matter at high redshift is important in determining the number of ultra-faint dwarf galaxies at $z=0$. The new model in A-SLOTH provides a framework to study the stellar properties and the formation history of metal-poor stars in Milky Way and its satellites.

description: We present a study designed to measure the average LyC escape fraction ($\langle f_{\rm esc}\rangle$) of star-forming galaxies at z=3.5. We assemble a sample of 148 galaxies from the VANDELS survey at $3.35\leq z_{\rm spec}\leq3.95$, selected to minimize line-of-sight contamination of their photometry. For this sample, we use ultra-deep, ground-based, $U-$band imaging and HST $V-$band imaging to robustly measure the distribution of $\mathcal{R_{\rm obs}}$ $=(L_{\rm LyC}/L_{\rm UV})_{\rm obs}$. We then model the distribution as a function of $\langle f_{\rm esc}\rangle$, carefully accounting for attenuation by dust, and the IGM (and CGM). A maximum likelihood fit to the $\mathcal{R_{\rm obs}}$ distribution returns a best-fitting value of $\langle f_{\rm esc}\rangle =0.07\pm0.02$, a result confirmed using an alternative Bayesian inference technique (both exclude $\langle f_{\rm esc}\rangle=0.0$ at $> 3σ$). By splitting our sample in two, we find evidence that $\langle f_{\rm esc}\rangle$ is positively correlated with Ly$α$ equivalent width, with high and low sub-samples returning best fits of $\langle f_{\rm esc}\rangle=0.12^{+0.06}_{-0.04}$ and $\langle f_{\rm esc} \rangle=0.02^{+0.02}_{-0.01}$, respectively. In contrast, we find evidence that $\langle f_{\rm esc}\rangle$ is anti-correlated with intrinsic UV luminosity and UV dust attenuation; with low UV luminosity and dust attenuation sub-samples returning best fits in the range $0.10 \leq \langle f_{\rm esc}\rangle \leq 0.22$. We do not find evidence for a clear correlation between $f_{\rm esc}$ and galaxy stellar mass, suggesting it is not a primary indicator of leakage. Although larger samples are needed to further explore these trends, they suggest that it is entirely plausible that the low dust and metallicity galaxies found at z > 6 will display the $\langle f_{\rm esc}\rangle\geq0.1$ required to drive reionization.
