description: This paper traces the perceptions of the agricultural sector held by economists over the last three centuries, with particular emphasis on how the evolution of these ideas has influenced the state of present-day thinking about the economic role of agriculture in developed and developing economies. The paper begins with the seventeenth and eighteenth centuries, leading to a consideration of the place of agriculture in the work of the major figures of classical political economy from Adam Smith to Marx. The rise of neo-classical economics, and its influence on twentieth century thinking, is discussed. In the contemporary period, particular attention is paid to agriculture in development theory, with an assessment of conflicting theoretical ideas about the role of the agricultural sector during the process of economic transformation and growth. The paper concludes with a consideration of the current state of economic thought about the role of agriculture in the economy, and makes some observations on likely future directions.

description: To make best use of multi-faceted astronomical and nuclear data-sets, probability distributions of neutron star models that can be used to propagate errors consistently from one domain to another are required. We take steps toward a consistent model for this purpose, highlight where model inconsistencies occur and assess the resulting model uncertainty. Using two distributions of nuclear symmetry energy parameters - one uniform, the other based on pure neutron matter theory, we prepare two ensembles of neutron star inner crust models. We use an extended Skyrme energy-density functional within a compressible liquid drop model (CLDM). We fit the surface parameters of the CLDM to quantum 3D Hartree-Fock calculations of crustal nuclei. All models predict more than 50% of the crust by mass and 15% of the crust by thickness comprises pasta with medians of around 62% and 30% respectively. We also present 68% and 95% ranges for the crust composition as a function of density. We examine the relationships between crust-core boundary and pasta transition properties, the thickness of the pasta layers, the symmetry energy at saturation and sub-saturation densities and the neutron skins of 208Pb and 48Ca. We quantify the correlations using the maximal information coefficient, which can effectively characterize non-linear relationships. Future measurements of neutron skins, information from nuclear masses and giant resonances, and theoretical constraints on PNM will be able to place constraints on the location of the pasta and crust-core boundaries and the amount of pasta in the crust.

description: Charge profiles in liquid electrolytes are of crucial importance for applications, such as supercapacitors, fuel cells, batteries, or the self-assembly of particles in colloidal or biological settings. However, creating localised (screened) charge profiles in the bulk of such electrolytes, generally requires the presence of surfaces -- for example, provided by colloidal particles or outer surfaces of the material -- which poses a fundamental constraint on the material design. Here, we show that topological defects in nematic electrolytes can perform as regions for local charge separation, forming charged defect cores and in some geometries even electric multilayers, as opposed to the electric double layers found in isotropic electrolytes. Using a Landau-de Gennes-Poisson-Boltzmann theoretical framework, we show that ions highly effectively couple with the topological defect cores via ion solvability, and with the local director-field distortions of the defects via flexoelectricity. The defect charging is shown for different defect types -- lines, points, and walls -- using geometries of ionically screened flat isotropic-nematic interfaces, radial hedgehog point defects and half-integer wedge disclinations in the bulk and as stabilised by (charged) colloidal particles. More generally, our findings are relevant for possible applications where topological defects act as diffuse ionic capacitors or as ionic charge carriers.

Description
Specimen TUG 1745-47 is a slightly curved fragment of a mature body chamber with a length of ca 35 mm and a maximum diameter of 20 mm. Approximately five annulations occur in a distance similar to the conch diameter. The surface is ornamented with ca 40 longitudinal lirae around the circumference and fine growth lines. At its base, the fragment has a diameter of 19 mm and a chamber of the phragmocone is preserved with two septa which are 5 mm distant. The septa are located in the troughs of the respective annulations and are directly transverse, parallel to the annulations. The septal foramen is poorly preserved but apparently slightly eccentric in position and located toward the convex side of the conch curvature.
Specimen TUG 939-30 (Fig. 12J) is a nearly tubular fragment of a body chamber with relatively well-preserved conch surface showing ca 40 longitudinal lirae across the circumference and fine transverse lirae or raised growth lines (ca 10–12 per cycle of annulation). The spacing of the annulation is relatively narrow with 5–6 cycles of annulations per distance similar to the corresponding conch cross section.
Remarks
No new data on the internal characters of this species can be added with the Estonian material. The species was originally placed within Dawsonoceras. However, based on the similarity of the known characters from this species with other species of Gorbyoceras and following the more restricted genus diagnosis of Dawsonoceras of Horny (1956), followed herein (see above), a placement within Gorbyoceras is suggested, herein.

description: In "extended phase space" approach to quantum geometrodynamics numerical solutions to Schrodinger equation corresponding to various choice of gauge conditions are obtained for the simplest isotropic model. The "extended phase space" approach belongs to those appeared in the last decade in which, as a result of fixing a reference frame, the Wheeler - DeWitt static picture of the world is replaced by evolutionary quantum geometrodynamics. Some aspects of this approach were discussed at two previous PIRT meetings. We are interested in the part of the wave function depending on physical degrees of freedom. Three gauge conditions having a clear physical meaning are considered. They are the conformal time gauge, the gauge producing the appearance of Lambda-term in the Einstein equations, and the one covering the two previous cases as asymptotic limits. The interpretation and discussion of the obtained solutions is given.

description: We present a six-dimensional $\mathcal{N}=(1,0)$ supersymmetric higher gauge theory in which self-duality is consistently implemented by physically trivial additional fields. The action contains both $\mathcal{N}=(1,0)$ tensor and vector multiplets and is non-trivially interacting. The tensor multiplet part is loosely related to a recently proposed action by Sen that leads to on-shell self-duality in an elegant way. As we also show, Sen's action finds a very natural and direct interpretation from a homotopy algebraic perspective.

description: In this work it is investigated if fermionic sources could be responsible for accelerated periods during the evolution of a universe where a matter field would answer for the decelerated period. The self-interaction potential of the fermionic field is considered as a function of the scalar and pseudo-scalar invariants. Irreversible processes of energy transfer between the matter and gravitational fields are also considered. It is shown that the fermionic field could behave like an inflaton field in the early universe and as dark energy for an old universe.

description: In condensed matter systems it is necessary to distinguish between the momentum of the constituents of the system and the pseudomomentum of quasiparticles. The same distinction is also valid for angular momentum and pseudoangular momentum. Based on Noether's theorem, we demonstrate that the recently discussed orbital angular momenta of phonons and magnons are pseudoangular momenta. This conceptual difference is important for a proper understanding of the transfer of angular momentum in condensed matter systems, especially in spintronics applications.

Dawsonoceras sp. – Kröger & Isakar 2006: 157, figs 10e, j, 12h.
Diagnosis
Dawsonoceras with angle of expansion of ca. 5° and circular cross section; ca. five relatively shallow annulations occur at a distance similar to shell diameter; approximately 40 longitudinal lirae occur around shell circumference, more than 10 pronounced transverse striae occur per cycle of annulations; septal necks achoanitic; siphuncle subcentral, fusiform, expanded within chambers.
Etymology
In honor of Heino Stumbur (Tallinn), an Estonian geologist and paleontologist who first described this form in his unpublished diploma thesis (Stumbur 1955) under the nomen nudum of Spyroceras paulum.
Holotype
PMU 26717.
Type locality and horizon
Kallholn, Siljan District, Sweden, Boda Limestone, Boda Core Member, late Katian, Ordovician.
Description
The holotype is a piece of phragmocone with a length of 72 mm and a diameter of 14–20 mm (angle of expansion 5°), with a circular conch cross section. The sutures are directly transverse, with a distance of 3 mm at a diameter of 15 mm (0.2 of corresponding conch cross section; Fig. 16E). The conch is ornamented with 40 distinctly raised longitudinal lirae around circumference. Additionally, the conch is annulated. The distance between two successive annulations is 3.5 mm at a corresponding conch diameter of 16 mm (0.22 of distance similar to corresponding conch diameter). Approximately 20 distinct and directly transverse striae occur in a single cycle of annulation (Fig. 17B).
Comparison
This species differs from D. fenestratum in having a higher number of longitudinal lirae (ca. 20–30 in D. fenestratum against ca. 40 in D. stumburi sp. nov.). Additionally, the transverse annulation appears to be less pronounced and slightly more widely spaced in D. stumburi sp. nov., but the transverse striae are narrower than in D. fenestratum.
The external characters of D. stumburi sp. nov. are identical to those of Orthoceras clathratum Hall, 1847 from the Katian Middleville Formation of New York (see, e.g., Foerste 1928). But a synonymization is at present not possible, as the internal characters of this species are not known.

Photogalvanic Effect in Silicene

description: Silicene has introduced itself as an outstanding novel material, which seeks its meritorious place among common spintronic devices like Cu and Ag. In this work, photogalvanic effect in silicene is studied within the semi-classical approach and beyond Dirac point approximation. Normal electric field plays the role of effective pseudo-magnetic field which breaks the inversion symmetry and splits the conduction and valence bands. The interplay between this external field and intrinsic spin-orbit coupling provides spin-valley locking in silicene. Spin-valley locking in silicene makes this material superior to its carbon counterpart, graphene. Since the absorption of the polarized photons is not equivalent at both of the valleys, spin-valley locking leads to a spin-polarized photocurrent injection.

description: This paper studies how groups resolve disagreement when they must reach unanimity after submitting individual proposals and exchanging text-form messages via a chat window in lottery choice experiments. We find that the majority proposal does not always prevail. The minority proposal prevails sometimes, especially when it is closer to risk neutrality. About one third of the groups disagrees after communication and would have got zero payoffs if disagreement remains after two more attempts without communication. In these groups, extrovert subjects are more likely to lead the group outcome than confused or conscientious subjects. Overall group choices are more coherent and closer to risk neutrality than individuals’. Checking the recorded messages, we find that the chat activity is intense, growing with the level of disagreement and aims at finding consensus. The amount and timing of chat messages help us to predict which
choice prevails in the group.

description: The current crisis puts at issue the self-regulated market system of
monitoring and control. Claims for restoring the proper functioning of
market economies in general, and financial markets in particular, call for
either establishing new sets of rules or creating new supervising authorities.
Both claims rely on the received mantra of full independence that applies
whenever control is concerned. However, our analysis pays attention to a
neglected aspect of monitoring and control, which requires the capability to
discovering and understanding flaws in and dangers from the inner
congeries of the business affair under examination. Arguably, this businessspecific
expertise and independence trade off. To overcome this problem, an
optimal share of non-independent controllers may be chosen from or
appointed by stakeholding constituencies of the business affair. They can
provide proficient monitoring and control without colluding, in principle,
with executive managers of the activity to be controlled.

description: Existing vision-based action recognition is susceptible to occlusion and appearance variations, while wearable sensors can alleviate these challenges by capturing human motion with one-dimensional time-series signal. For the same action, the knowledge learned from vision sensors and wearable sensors, may be related and complementary. However, there exists significantly large modality difference between action data captured by wearable-sensor and vision-sensor in data dimension, data distribution and inherent information content. In this paper, we propose a novel framework, named Semantics-aware Adaptive Knowledge Distillation Networks (SAKDN), to enhance action recognition in vision-sensor modality (videos) by adaptively transferring and distilling the knowledge from multiple wearable sensors. The SAKDN uses multiple wearable-sensors as teacher modalities and uses RGB videos as student modality. To preserve local temporal relationship and facilitate employing visual deep learning model, we transform one-dimensional time-series signals of wearable sensors to two-dimensional images by designing a gramian angular field based virtual image generation model. Then, we build a novel Similarity-Preserving Adaptive Multi-modal Fusion Module to adaptively fuse intermediate representation knowledge from different teacher networks. Finally, to fully exploit and transfer the knowledge of multiple well-trained teacher networks to the student network, we propose a novel Graph-guided Semantically Discriminative Mapping loss, which utilizes graph-guided ablation analysis to produce a good visual explanation highlighting the important regions across modalities and concurrently preserving the interrelations of original data. Experimental results on Berkeley-MHAD, UTD-MHAD and MMAct datasets well demonstrate the effectiveness of our proposed SAKDN.

description: We investigate the viability of extending the Standard Model with $S_1$ and $S_3$ scalar leptoquarks when the flavour structure is parametrized in terms of Froggatt-Nielsen charges. In contrast to a similar analysis with a vector leptoquark, we find essentially two solutions for the charges that fit the experimental constraints, which are dominated by the current tensions in $B$ decays. These two scenarios differ in their estimate of the anomalous magnetic moment of the muon, $(g-2)$, but they both predict sizeable contributions to $τ\toμγ$, $\bar B_s\toτ^\pmμ^\mp$ and $B^+\to K^+τ^+μ^-$ decays, whose branching ratios are close to the current experimental limits.

description: PSR B1259-63 is in a highly eccentric 3.4 year orbit with a Be star and crosses the Be star disc twice per orbit, just prior to and just after periastron. Unpulsed radio, X-ray and gamma-ray emission observed from the binary system is thought to be due to the collision of pulsar wind with the wind of Be star. We present here the results of new XMM-Newton observations of the PSR B1259-63 system during the beginning of 2004 as the pulsar approached the disc of Be star.We combine these results with earlier unpublished X-ray data from BeppoSAX and XMM-Newton as well as with ASCA data. The detailed X-ray lightcurve of the system shows that the pulsar passes (twice per orbit) through a well-defined gaussian-profile disk with the half-opening angle (projected on the pulsar orbit plane) ~18.5 deg. The intersection of the disk middle plane with the pulsar orbital plane is inclined at ~70 deg to the major axis of the pulsar orbit. Comparing the X-ray lightcurve to the TeV lightcurve of the system we find that the increase of the TeV flux some 10--100 days after the periastron passage is unambiguously related to the disk passage. At the moment of entrance to the disk the X-ray photon index hardens from 1.8 up to 1.2 before returning to the steeper value 1.5. Such behaviour is not easily accounted for by the model in which the X-ray emission is synchrotron emission from the shocked pulsar wind. We argue that the observed hardening of the X-ray spectrum is due to the inverse Compton or bremsstrahlung emission from 10-100 MeV electrons responsible for the radio synchrotron emission.

provided by ALTAIR, the objective of this award is to provide and recognize the use
of CAE (Computer-Aided Engineering) simulation on Cairo university Team's Urban
Car. This report and the analysis were represented during Shell Eco-Marathon 2021.
As ALTAIR supported the teams participated in the marathon by providing not just
free Altair software, but also some important virtual learning sessions to help and aid
teams to improve their designs and performance. Simulation-driven design methods
will be included with all the steps and results, and how could Altair software products
help us to handle this improvement. Finite element analysis (FEA) is mandatory for
design stages for either the chassis or the body. Altair Hypermesh with Opti structure
solver ease the cycle of meshing and applying the basic analyses which applied to the
car and applying a robust optimization to save some weight without decreasing the
stiffness of the car with free sized optimization, with the aid of Hyperworks software
for making some modifications on the CAD, like Snitching, suppress edges, or filling
surfaces. Computational Fluid Dynamics (CFD) analysis is done using AcuSolve
solver and visualized with the aid of AcuFieldView.

description: In two-way time-of-arrival (TOA) systems, a user device (UD) obtains its position and timing information by round-trip communications to a number of anchor nodes (ANs) at known locations. Compared with the one-way TOA technique, the two-way TOA scheme is easy to implement and has higher localization and synchronization accuracy. Existing two-way TOA methods assume a stationary UD. This will cause uncompensated position and timing errors. In this article, we propose an optimal maximum likelihood (ML) based two-way TOA localization and synchronization method, namely TWLAS. Different from the existing methods, it takes the UD mobility into account to compensate the error caused by the UD motion. We analyze its estimation error and derive the Cramer-Rao lower bound (CRLB). We show that the conventional two-way TOA method is a special case of the TWLAS when the UD is stationary, and the TWLAS has high estimation accuracy than the conventional one-way TOA method. We also derive the estimation error in the case of deviated UD velocity information. Numerical result demonstrates that the estimation accuracy of the new TWLAS for a moving UD reaches CRLB, better than that of the conventional one-way TOA method, and the estimation error caused by the deviated UD velocity information is consistent with the theoretical analysis.

description: We establish a procedure to track the tax valuation history of properties that are fully or partially restricted with conservation easements to test the assertion that easements result in lower property valuations. Easements didn't decrease property valuations; they merely decreased the rate of value for the affected properties. On average, the restricted properties' valuations increased at a rate lower than did those for unrestricted properties - but not always, and certainly not uniformly. Valuation policy is specific to the local tax assessor: no sweeping assertions about easements and property taxes is warranted.

description: Deep Learning using the eponymous deep neural networks (DNNs) has become an attractive approach towards various data-based problems of theoretical physics in the past decade. There has been a clear trend to deeper architectures containing increasingly more powerful and involved layers. Contrarily, Taylor coefficients of DNNs still appear mainly in the light of interpretability studies, where they are computed at most to first order. However, especially in theoretical physics numerous problems benefit from accessing higher orders, as well. This gap motivates a general formulation of neural network (NN) Taylor expansions. Restricting our analysis to multilayer perceptrons (MLPs) and introducing quantities we refer to as propagators and vertices, both depending on the MLP's weights and biases, we establish a graph-theoretical approach. Similarly to Feynman rules in quantum field theories, we can systematically assign diagrams containing propagators and vertices to the corresponding partial derivative. Examining this approach for S-wave scattering lengths of shallow potentials, we observe NNs to adapt their derivatives mainly to the leading order of the target function's Taylor expansion. To circumvent this problem, we propose an iterative NN perturbation theory. During each iteration we eliminate the leading order, such that the next-to-leading order can be faithfully learned during the subsequent iteration. After performing two iterations, we find that the first- and second-order Born terms are correctly adapted during the respective iterations. Finally, we combine both results to find a proxy that acts as a machine-learned second-order Born approximation.

Year: 1961
Subjects: subject: Transportation Engineering

description: When the Maintenance Division found it necessary to resurface the Clark Memorial and Ashland-Coal Grove Bridges in 1958, a thin, silica sand-asphalt, wearing surface was recommended by the Research Division. The basis of the recommendations was the promising results obtained in laboratory testing and the apparently successful resurfacing of bridges with thin applications of silica sand-asphalt in the New York Area and elsewhere. The design and construction details pertaining to these two projects have been reported previously. This report is a record of the performance of the two projects and of the repair of spalled areas on the deck of Clark Memorial Bridge.
Squeezing in Floer theory and refined Hofer-Zehnder capacities of sets near symplectic submanifolds

description: We use Floer homology to study the Hofer-Zehnder capacity of neighborhoods near a closed symplectic submanifold M of a geometrically bounded and symplectically aspherical ambient manifold. We prove that, when the unit normal bundle of M is homologically trivial in degree dim(M) (for example, if codim(M) > dim(M)), a refined version of the Hofer-Zehnder capacity is finite for all open sets close enough to M. We compute this capacity for certain tubular neighborhoods of M by using a squeezing argument in which the algebraic framework of Floer theory is used to detect nontrivial periodic orbits. As an application, we partially recover some existence results of Arnold for Hamiltonian flows which describe a charged particle moving in a nondegenerate magnetic field on a torus. We also relate our refined capacity to the study of Hamiltonian paths with minimal Hofer length.

Discrete shedding of secondary vortices along a modified Kaden spiral

description: When an object is accelerated in a fluid, a primary vortex is formed through the roll-up of a shear layer. This primary vortex does not grow indefinitely and will reach a limiting size and strength. Additional vorticity beyond the critical limit will end up in a trailing shear layer and accumulate into secondary vortices. The secondary vortices are typically considerably smaller than the primary vortex. Here, we focus on the formation, shedding, and trajectory of secondary vortices generated by a rotating rectangular plate in a quiescent fluid using time-resolved particle image velocimetry. The Reynolds number (Re) is varied from 840 to 11150. At low Re, the shear layer is a continuous uninterrupted layer of vorticity that rolls up into a single coherent primary vortex. At Re=1955, the shear layer becomes unstable. For Re>4000, secondary vortices are discretely released from the plate tip. First, we demonstrate that the roll-up of the shear layer, the trajectory of the primary vortex, and the path of secondary vortices can be predicted by a modified Kaden spiral. Second, the timing of the secondary vortex shedding is analysed. The time interval between the release of successive secondary vortices is not constant during the rotation but increases the more vortices have been shed. The shedding time interval also increases with decreasing Reynolds number. The increased time interval under both conditions is due to a reduced circulation feeding rate.

description: We test cosmological hydrodynamical simulations of galaxy formation regarding the properties of the Blue Cloud (BC), Green Valley (GV) and Red Sequence (RS), as measured on the 4000$\small{ \mathring {\mathrm A}}$ break strength vs stellar mass plane at $z=0.1$. We analyse the RefL0100N1504 run of EAGLE and the TNG100 run of IllustrisTNG project, by comparing them with the Sloan Digital Sky Survey, while taking into account selection bias. Our analysis focuses on the GV, within stellar mass $\log\,\mathrm{M_\star/M_{\odot}} \simeq 10-11$, selected from the bimodal distribution of galaxies on the D$_n$(4000) vs stellar mass plane, following Angthopo et al. methodology. Both simulations match the fraction of AGN in the green-valley. However, they over-produce quiescent GV galaxies with respect to observations, with IllustrisTNG yielding a higher fraction of quiescent GV galaxies than EAGLE. In both, GV galaxies have older luminosity-weighted ages with respect to the SDSS, while a better match is found for mass-weighted ages. We find EAGLE GV galaxies quench their star formation early, but undergo later episodes of star formation, matching observations. In contrast, IllustrisTNG GV galaxies have a more extended SFH, and quench more effectively at later cosmic times, producing the excess of quenched galaxies in GV compared with SDSS, based on the 4000$\small{ \mathring {\mathrm A}}$ break strength. These results suggest the AGN feedback subgrid physics, more specifically, the threshold halo mass for black hole input and the black hole seed mass, could be the primary cause of the over-production of quiescent galaxies found with respect to the observational constraints.

Non-linear ladder operators and coherent states for the 2:1 oscillator

description: The 2:1 two-dimensional anisotropic quantum harmonic oscillator is considered and new sets of states are defined by means of normal-ordering non-linear operators through the use of non-commutative binomial theorems as well as solving recurrence relations. The states generated are good candidates for the natural generalisation of the $\mathfrak{su}(2)$ coherent states of the two-dimensional isotropic oscillator. The two-dimensional non-linear generalised ladder operators lead to several chains of states which are connected in a non trivial way. The uncertainty relations of the defining chain of states are calculated and it is found that they admit a resolution of the identity and the spatial distribution of the wavefunction produces Lissajous figures in correspondence with the classical 2:1 oscillator.

description: Photonic crystals create dramatic new possibilities for nonlinear optics. Line defects are shown to support modes suitable for the production of pairs of photons by the material's second order nonlinearity even if the phase-matching conditions cannot be satisfied in the bulk. These structures offer the flexibility to achieve specific dispersion characteristics and potentially very high brightness. In this work, two phase matching schemes are identified and analyzed regarding their dispersive properties.

Spectral weight redistribution in strongly correlated bosons in optical lattices

description: We calculate the single-particle spectral function for the one-band Bose-Hubbard model within the random phase approximation (RPA). In the strongly correlated superfluid, in addition to the gapless phonon excitations, we find extra gapped modes which become particularly relevant near the superfluid-Mott quantum phase transition (QPT). The strength in one of the gapped modes, a precursor of the Mott phase, grows as the QPT is approached and evolves into a hole (particle) excitation in the Mott insulator depending on whether the chemical potential is above (below) the tip of the lobe. The sound velocity of the Goldstone modes remains finite when the transition is approached at a constant density, otherwise, it vanishes at the transition. It agrees well with Bogoliubov theory except close to the transition. We also calculate the spatial correlations for bosons in an inhomogeneous trapping potential creating alternating shells of Mott insulator and superfluid. Finally, we discuss the capability of the RPA approximation to correctly account for quantum fluctuations in the vicinity of the QPT.

A Machine-Laid Surmountable Bituminous Concrete Median

Subjects: subject: Transportation Engineering

description: On August 28, 1961, personnel of the Research Division were requested to observe a demonstration of a newly developed Etnyre Median Paver. The demonstration was given at the Lehman-Roberts Company plant in Lexington, and was arranged primarily for the benefit of the paving contractor working on Euclid Avenue in Lexington. The paving contract called for the construction of a surmountable bituminous concrete median which, to our understanding, is the first instance for construction of that type to be machine-laid. Some doubts arose during the demonstration as to the ability of the machine to hold alignment and to give adequate compaction.  Following the demonstration, it seemed advisable to examine the finished median from the standpoint of density and stability. Representatives of the Division of Design, present at the demonstration, requested that the Research Division examine and evaluate a short trial-section of the median. The trial-section, approximately 25 ft. long, was laid that afternoon on the lot of the Thompson, King and Tate Ready-Mix Concrete Company in Lexington.
