description: The lowest critical point of one unitary matrix model with cosine plus logarithmic potential is known to correspond with the $(A_1, A_3)$ Argyres-Douglas (AD) theory and its double scaling limit derives the Painlevé II equation with parameter. Here, we consider the critical points associated with all cosine potentials and determine the scaling operators, their vevs and their scaling dimensions from perturbed string equations at planar level. These dimensions agree with those of $(A_1,A_{4k-1})$ AD theory.

description: In the region defined by the cities of Kozani, Eani and Servia, a Neogene basin is being developed occupying an area of about 400 km2. In this basin two series of deposits are distinguished: a) The Lower Neogene Series which mainly consists of sandstones, claystones and marls containing lignite bodies and b) The Upper Neogene Series which is consisted of dolomite marls, sandstones, diatomites and unconsolidated volcanic ash of an approximate thickness of 20 cm, formations that contain layered, lenticular and nodular deposits of white, mainly magnesium containing, minerals of sedimentary origin. These deposits contain fluctuating amounts of magnesite (MgCO3), huntite [Mg3Ca(CO3)4], hydromagnesite [Mg5(CO3)4⋅4H2O] and aragonite (CaCO3) and they usually have a very bright white color. The above carbonate minerals have been most likely deposited in small swamps of lake areas, which were supplied with upward flowing fluids. In this doctoral thesis fifteen samples of huntite / hydromagnesite of the region Leukara of Kozani, as well as a soil sample, are examined

description: Enhancing absorption in optically thin semiconductors is the key in the development of high-performance optical and optoelectronic devices. In this paper, we resort to the concept of degenerate critical coupling and design an ultra-thin semiconductor absorber composed of free-standing GaAs nanocylinder metasurfaces in the near infrared. The numerical results show that perfect absorption can be achieved through overlapping two Mie modes with opposite symmetry, with each mode contributing a theoretical maximum of 50% in their respective critical coupling state. The absorption also shows the polarization-independent and angle-insensitive robustness. This work, together with the design concept, opens up great opportunities for the realization of high-efficiency metasurface devices, including optical emitters, modulators, detectors, and sensors.

description: A Reeb vector field satisfies the Kupka-Smale condition when all its closed orbits are non-degenerate, and the stable and unstable manifolds of its hyperbolic closed orbits intersect transversely. We show that, on a closed 3-manifold, any Reeb vector field satisfying the Kupka-Smale condition admits a Birkhoff section. In particular, this implies that the Reeb vector field of a $C^\infty$-generic contact form on a closed 3-manifold admits a Birkhoff section, and that the geodesic vector field of a $C^\infty$-generic Riemannian metric on a closed surface admits a Birkhoff section.

description: U.S. wheat exports have expanded significantly since passage of the Food Security Act of 1985, fulfilling the act's objective to make the United States more competitive in world grain markets. The Export Enhancement Program and lower wheat loan rates, both authorized by the 1985 Act, were major factors in the growing U.S. wheat export market. The act accounts for a significant portion of the recent increase in wheat exports. Other factors beyond the control of U.S. policymakers also contributed to the rise in wheat exports: smaller yields of U.S. wheat competitors and higher import demand by the Soviet Union and China. This bulletin identifies factors that expanded recent wheat exports. It finds that policy effectiveness changes as market conditions change.

description: The spread of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become a global health crisis. The binding affinity of SARS-CoV-2 (in particular the receptor binding domain, RBD) to its receptor angiotensin converting enzyme 2 (ACE2) and the antibodies is of great importance in understanding the infectivity of COVID-19 and evaluating the candidate therapeutic for COVID-19. In this work, we propose a new method based on molecular mechanics/Poisson-Boltzmann surface area (MM/PBSA) to accurately calculate the free energy of SARS-CoV-2 RBD binding to ACE2 and antibodies. The calculated binding free energy of SARS-CoV-2 RBD to ACE2 is -13.3 kcal/mol, and that of SARS-CoV RBD to ACE2 is -11.4 kcal/mol, which agrees well with experimental result (-11.3 kcal/mol and -10.1 kcal/mol, respectively). Moreover, we take two recently reported antibodies as the example, and calculate the free energy of antibodies binding to SARS-CoV-2 RBD, which is also consistent with the experimental findings. Further, within the framework of the modified MM/PBSA, we determine the key residues and the main driving forces for the SARS-CoV-2 RBD/CB6 interaction by the computational alanine scanning method. The present study offers a computationally efficient and numerically reliable method to evaluate the free energy of SARS-CoV-2 binding to other proteins, which may stimulate the development of the therapeutics against the COVID-19 disease in real applications.

description: Presentation given at the 2018 Farm Woodland Forum meeting held at the Allerton Project, UK on 10th and 11th July by Paul Burgess, Cranfield University: Lessons learnt for livestock agroforestry in the AGFORWARD project This presentation will review the lessons learnt from using trees and shrubs in livestock systems from various stakeholder groups across Europe. The improved seasonality of grass production under trees was a key benefit within beef and sheep systems in Spain and the UK. In Epping Forest near London, the use of "invisible fencing" allow unconstrained public access to an important area for recreation. In Herefordshire, the use of sheep within high stem apple orchards reduced mowing costs and provided additional grass for sheep production. Work by the Organic Research Centre highlighted how grass swards can be established in poultry systems. In Italy and the Netherlands, trees reduced the level of heat stress experienced by outdoor pigs. Partners in the Netherlands led on the production of an tree fodder database, where leaves of black locust, chestnut, white mulberry and ash can have crude protein levels of 22%.

description: Farmers sponsor generic advertising campaigns to expand the total market for their commodity. Generic advertising promotes a type of food, such as milk, beef, or orange juice, rather than a specific company's brand. Sales promotions may help increase consumer demand and raise—or at least stabilize—commodity prices. If producers can improve their domestic markets through generic advertising, some pressure on price supports and other traditional farm policy tools could be relieved. The growth in promotions has spurred public debate about the costs and benefits for producers, and the effect on food budgets and choices for consumers. Do producers gain from advertising, and if so, do consumers pay the price in their food bills?
BKP tau-functions as square roots of KP tau-functions

description: It is well-known that a BKP tau-function is the square root of a certain KP tau-function, provided one puts the even KP times equal to zero. In this paper we compute for all polynomial BKP tau-function its corresponding KP "square". We also give, in the polynomial case, a representation theoretical proof of a recent result by Alexandov, viz. that a KdV tau-function becomes a BKP tau-function when one divides all KdV times by 2.

description: Presentation given at the 2018 Farm Woodland Forum meeting held at the Allerton Project, UK by Matthew Axe, Royal Agricultural University, Cirencester: Utilising hedgerows for landscape scale carbon sequestration. Hedgerows are a prominent agroforestry system in England and Wales, an estimated 456 000 km of these being actively managed. The use of hedgerows to sequester atmospheric carbon (C) was proposed by Falloon et al. 2004. Their models for field boundaries showed between 0.1 to 2.4% of 1990 UK CO2-C emissions could be sequestered, however, hedgerow options focused on planting new hedges on existing arable field margins. Following a study of hedgerow C stocks on a lowland arable farm, the means in which existing hedgerow features could sequester C was scrutinised. This considers how long-term management cycles affect C stocks.

description: We investigate the dynamics of an effectively one-dimensional Bose-Einstein condensate (BEC) with scattering length $a$ subjected to a spatially periodic modulation, $a=a(x)=a(x+L)$. This "collisionally inhomogeneous" BEC is described by a Gross-Pitaevskii (GP) equation whose nonlinearity coefficient is a periodic function of $x$. We transform this equation into a GP equation with constant coefficient $a$ and an additional effective potential and study a class of extended wave solutions of the transformed equation. For weak underlying inhomogeneity, the effective potential takes a form resembling a superlattice, and the amplitude dynamics of the solutions of the constant-coefficient GP equation obey a nonlinear generalization of the Ince equation. In the small-amplitude limit, we use averaging to construct analytical solutions for modulated amplitude waves (MAWs), whose stability we subsequently examine using both numerical simulations of the original GP equation and fixed-point computations with the MAWs as numerically exact solutions. We show that "on-site" solutions, whose maxima correspond to maxima of $a(x)$, are significantly more stable than their "off-site" counterparts.

description: Complex interactions between cellular systems and their surrounding extracellular matrices are emerging as important mechanical regulators of cell functions such as proliferation, motility, and cell death, and such cellular systems are often characterized by pulsating acto-myosin activities. Here, using an active gel model, we numerically explore the spontaneous flow generation by activity pulses in the presence of a viscoelastic medium. The results show that cross-talk between the activity-induced deformations of the viscoelastic surroundings with the time-dependent response of the active medium to these deformations can lead to the reversal of spontaneously generated active flows. We explain the mechanism behind this phenomenon based on the interaction between the active flow and the viscoelastic medium. We show the importance of relaxation timescales of both the polymers and the active particles and provide a phase-space over which such spontaneous flow reversals can be observed. Our results suggest new experiments investigating the role of controlled pulses of activity in living systems ensnared in complex mircoenvironments.

description: Rotational transformations describe relativistic effects in rotating frames. There are four major kinematic rotational transformations: the Langevin metric; Post transformation; Franklin transformation; and the rotational form of the absolute Lorentz transformation. The four transformations exhibit different combinations of relativistic effects and simultaneity frameworks, and generate different predictions for relativistic phenomena. Here, the predictions of the four rotational transformations are compared with recent optical data that has sufficient resolution to distinguish the transformations. We show that the rotational absolute Lorentz transformation matches diverse relativistic optical and non-optical rotational data. These include experimental observations of length contraction, directional time dilation, anisotropic one-way speed of light, isotropic two-way speed of light, and the conventional Sagnac effect. In contrast, the other three transformations do not match the full range of rotating-frame relativistic observations.

description: We show that a 3-qubit system as studied for quantum information purposes can alternatively be used as a thermodynamic machine when driven in finite time and interfaced between two split baths. The spins are arranged in a chain where the working spin in the middle exercises Carnot cycles the area of which defines the exchanged work. The cycle orientation (sign of the exchanged work) flips as the difference of bath temperatures goes through a critical value.

description: We determine the 1-form symmetry group for any 4d N = 2 class S theory constructed by compactifying a 6d N=(2,0) SCFT on a Riemann surface with arbitrary regular untwisted and twisted punctures. The 6d theory has a group of mutually non-local dimension-2 surface operators, modulo screening. Compactifying these surface operators leads to a group of mutually non-local line operators in 4d, modulo screening and flavor charges. Complete specification of a 4d theory arising from such a compactification requires a choice of a maximal subgroup of mutually local line operators, and the 1-form symmetry group of the chosen 4d theory is identified as the Pontryagin dual of this maximal subgroup. We also comment on how to generalize our results to compactifications involving irregular punctures. Finally, to complement the analysis from 6d, we derive the 1-form symmetry from a Type IIB realization of class S theories.

Αρχικός στόχος υπήρξε η συλλογή κατά το δυνατόν του συνόλου των αττικών σαρκοφάγων που φέρουν τέτοιες παραστάσεις στην κύρια όψη, στις δευτερεύουσες πλευρές ή ακόμη σε δευτερεύουσες επιφάνειες του μνημείου ως παραπληρωματικά θέματα που αποδίδονται σε μικρογραφική κλίμακα. Από τις 182 ολόκληρες ή αποσπασματικά σωζόμενες σαρκοφάγους του καταλόγου πάνω από εκατό απεικονίζουν παραστάσεις ερωτιδέων. Η εικονογραφική μελέτη αυτών κατέδειξε ένα πλήθος θεμάτων ανάμεσα στα οποία ξεχωρίζει το διονυσιακό θέμα του κώμου. Στις παραστάσει αυτές κυρίαρχο είναι το θέμα του μεθυσμένου Ερωτιδέα που υποβαστάζεται από ένα σύντροφό του. Ενα από τα πιο συχνά απεικονιζόμενα μη διονυσιακά θέματα είναι οι Ερωτιδείς που οδηγούν άρματα. Οι ερωτιδείς που κυνηγούν απεικονίζονται συχνά στις δευτερεύουσες επιφάνειες των μνημείων. Εκτός από τις παραστάσεις των Ερωτιδέων στόχος της εργασίας υπήρξε η μελέτη του μοτίβου της γιρλάντας. Εβδομήντα από τις σαρκοφάγους του καταλόγου φέρουν παραστάσεις πέρα από την εικονογραφία, η αρχιτεκτονική μορφή των σαρκοφάγων, η χρονολόγησή τους, οι επιδράσεις που άσκησαν στα τοπικά εργαστήρια αποτέλεσαν θέματα που προσπαθήσαμε να προσεγγίσουμε
description: Aim of the research was the collection of the attic sarcophagi that carry representation of Putti and garlands. From a set of one hundred eighty two wholly or partlially preserved sarcophagi of the investigated material, more than hundred present scenes with Putti. The iconographical study of the above set indicated a series of thematic areas, amongst which the dionysiac theme of komos (κώμος). One of the most frequently depicted non dionysiac theme is this of Putti driving chariots. The hunting theme appears oftenly in the "secondary" sides of the monuments. Besides from the Putti representations, the garland motiv was studied. Garlands of the attic sarcophagi have two arcs. Exept from the iconographic study, we investigated the architectural form of the sarcophagi. Dating of the investigated monuments constituted one additional issue of the research. Additionally we made an attempt to approach the interpretation of the Putti representations. Finally, we tried to show light on the relationship between attic sarcophagi and those of Asia Minor and the roman ones

description: We report high-spectral resolution observations of comet 9P/Tempel 1 before, during and after the impact on 4 July 2005 UT of the Deep Impact spacecraft with the comet. These observations were obtained with the HIRES instrument on Keck 1. We observed brightening of both the dust and gas, but at different rates. We report the behavior of OH, NH, CN, C$_{3}$, CH, NH$_{2}$ and C$_{2}$ gas. From our observations, we determined a CN outflow velocity of at least 0.51 km sec$^{-1}$. The dust color did not change substantially. To date, we see no new species in our spectra, nor do we see any evidence of prompt emission. From our observations, the interior material released by the impact looks the same as the material released from the surface by ambient cometary activity. However, further processing of the data may uncover subtle differences in the material that is released as well as the time evolution of this material.

description: Correlations between 1-10 Hz quasi-periodic oscillations (QPOs) and spectral power law index have been reported for black hole (BH) candidate sources and one neutron star source, 4U 1728-34. An examination of QPO frequency and index relationships in Sco X-1 is reported herein. We discovered that Sco X-1, representing Z-source groups, can be adequately modeled by a simple two-component model of Compton up-scattering with a soft photon electron temperature of about 0.4 keV, plus an Iron K-line. The results show a strong correlation between spectral power law index and kHz QPOs. Because Sco X-1 radiates near the Eddington limit, one can infer that the geometrical configuration of the Compton cloud (CC) is quasi-spherical because of high radiation pressure in the CC. Thus, we conclude that the high Thomson optical depth of the Compton cloud, in the range of ~5-6 from the best-fit model parameters, is consistent with the neutron star's surface being obscured by material. Moreover, a spin frequency of Sco X-1 is likely suppressed due to photon scattering off CC electrons. Additionally, we demonstrate how the power spectrum evolves when Sco X-1 transitions from the horizontal branch to the normal branch.

description: Recent scientific developments are changing knowledge about risks in the food supply and revolutionizing procedures for controlling those risks. New tests reveal that micro-organisms are a more common cause of foodborne disease than most Americans suspect. New data on widely used chemicals sometimes show levels of residues so low that they were formerly undetectable. Rapid tests may improve monitoring of the critical control points in food production and distribution. The improved testing could trigger legal restrictions. Many food safety policies were adopted before these testing improvements. The challenge is to incorporate this new knowledge into workable food safety policies that take into account the economic costs and benefits of such regulation.

description: Anomalous diffusion, which shows a deviation of transport dynamics from the framework of standard Brownian motion, is involved in the evolution of various physical, chemical, biological, and economic systems. The study of such random processes is of fundamental importance in unveiling the physical properties of random walkers and complex systems. However, classical methods to characterize anomalous diffusion are often disqualified for individual short trajectories, leading to the launch of the Anomalous Diffusion (AnDi) Challenge. This challenge aims at objectively assessing and comparing new approaches for single trajectory characterization, with respect to three different aspects: the inference of the anomalous diffusion exponent; the classification of the diffusion model; and the segmentation of trajectories. In this article, to address the inference and classification tasks in the challenge, we develop a WaveNet-based deep neural network (WADNet) by combining a modified WaveNet encoder with long short-term memory networks, without any prior knowledge of anomalous diffusion. As the performance of our model has surpassed the current 1st places in the challenge leaderboard on both two tasks for all dimensions (6 subtasks), WADNet could be the part of state-of-the-art techniques to decode the AnDi database. Our method presents a benchmark for future research, and could accelerate the development of a versatile tool for the characterization of anomalous diffusion.

description: For an $r$-uniform hypergraph $H$, let $ν^{(m)}(H)$ denote the maximum size of a set~$M$ of edges in $H$ such that every two edges in $M$ intersect in less than $m$ vertices, and let $τ^{(m)}(H)$ denote the minimum size of a collection $C$ of $m$-sets of vertices such that every edge in $H$ contains an element of $C$. The fractional analogues of these parameters are denoted by $ν^{*(m)}(H)$ and $τ^{*(m)}(H)$, respectively. Generalizing a famous conjecture of Tuza on covering triangles in a graph, Aharoni and Zerbib conjectured that for every $r$-uniform hypergraph $H$, $τ^{(r-1)}(H)/ν^{(r-1)}(H) \leq \lceil{\frac{r+1}{2}}\rceil$. In this paper we prove bounds on the ratio between the parameters $τ^{(m)}$ and $ν^{(m)}$, and their fractional analogues. Our main result is that, for every $r$-uniform hypergraph~$H$, \[ τ^{*(r-1)}(H)/ν^{(r-1)}(H) \le \begin{cases} \frac{3}{4}r - \frac{r}{4(r+1)} &\text{for }r\text{ even,}\\ \frac{3}{4}r - \frac{r}{4(r+2)} &\text{for }r\text{ odd.} \\ \end{cases} \] This improves the known bound of $r-1$. We also prove that, for every $r$-uniform hypergraph $H$, $τ^{(m)}(H)/ν^{*(m)}(H) \le \operatorname{ex}_m(r, m+1)$, where the Turán number $\operatorname{ex}_r(n, k)$ is the maximum number of edges in an $r$-uniform hypergraph on $n$ vertices that does not contain a copy of the complete $r$-uniform hypergraph on $k$ vertices. Finally, we prove further bounds in the special cases $(r,m)=(4,2)$ and $(r,m)=(4,3)$.

Static quark-antiquark potential and Dirac eigenvector correlators

description: We represent the Polyakov loop correlator as a spectral sum of correlators of eigenvectors of the lattice Dirac operator. This spectral representation is studied numerically using quenched SU(3) configurations below and above the deconfinement temperature. We analyze whether the individual Dirac eigenvector correlators differ in the confined and deconfined phases. The decay properties of the normalized Dirac eigenvector correlators turn out to be essentially identical in the two phases, but the amplitudes change. This change of the amplitudes shifts the relative contributions of the individual Dirac eigenvector correlators and is the driving mechanism for the transition from the confining static potential into the deconfining one.
