description: Choice of weights is basic to construction of index numbers that are designed to measure change over time. The analysis in this article develops criteria for selection of weights and examines the results of using different periods as a basis for measuring change in the volume of selected inputs in farm production from 1910 to 1955. Laspeyres' weighted aggregative formula was considered the most appropriate formula for use in this analysis. Average cost rates were used as weighting units. The various indexes of combined inputs that are described here were developed for testing purposes. It is believed that the index of total farm inputs that will result when the aggregate production inputs of agriculture are measured and analyzed will differ substantially from any of the index-number series of selected agricultural inputs shown here. This paper is a report on the first phase of the project. It does not pretend to be an exhaustive study of the many problems that arise in the construction of an index of agricultural inputs. For instance, the problems associated with selection of weighting units and an index formula are not discussed. However, it is a reasonably thorough analysis of the problem of how to aggregate the different inputs in a meaningful way to show change over time when the composition, relative prices, and quantities of inputs change. The advice and leadership of Glen T. Barton in the preparation of this article is acknowledged by the author.

description: Agricultural economists and others engaged in agricultural research frequently have occasion to analyze the effect of changes in acreage and yield on crop production. This article describes a method of deriving statistical measures that summarize the relative influence of acreage and yield changes, respectively, on year-to-year variation in production. This method is applied to an analysis of several major crops to illustrate how the effect on production of changes in acreage and yield may be evaluated.

description: Supernova remnants interacting with molecular clouds are ideal laboratories to study the acceleration of particles at shock waves and their transport and interactions in the surrounding interstellar medium. In this paper, we focus on the supernova remnant W28, which over the years has been observed in all energy domains from radio waves to very-high-energy gamma rays. The bright gamma-ray emission detected from molecular clouds located in its vicinity revealed the presence of accelerated GeV and TeV particles in the region. An enhanced ionization rate has also been measured by means of millimetre observations, but such observations alone cannot tell us whether the enhancement is due to low energy (MeV) cosmic rays (either protons or electrons) or the X-ray photons emitted by the shocked gas. The goal of this study is to determine the origin of the enhanced ionization rate and to infer from multiwavelength observations the spectrum of cosmic rays accelerated at the supernova remnant shock in the unprecedented range spanning from MeV to multi-TeV particle energies. We developed a model to describe the transport of X-ray photons into the molecular cloud, and we fitted the radio, millimeter, and gamma-ray data to derive the spectrum of the radiating particles. The contribution from X-ray photons to the enhanced ionization rate is negligible, and therefore the ionization must be due to cosmic rays. Even though we cannot exclude a contribution to the ionization rate coming from cosmic ray electrons, we show that a scenario where cosmic ray protons explain both the gamma-ray flux and the enhanced ionization rate provides the most natural fit to multiwavelength data. This strongly suggests that the intensity of CR protons is enhanced in the region for particle energies in a very broad range covering almost 6 orders of magnitude: from $\lesssim 100$ MeV up to several tens of TeV.

description: We report all-electron, density-functional calculations with large Gaussian polarization basis set of the recently synthesized octahedral B24N24 cage that is perfectly round by symmetry, and boron-nitride (BN) clusters that its existence might suggest. We consider whether it is energetically possible that the two halves of this round cage could cap the BN nanotubes, modeled by B28N28 and B32N32. The energetics show that BN nanotubes with such round caps, are only slightly less favorable than the BN clusters containing six squares as the only defects in the otherwise perfect hexagonal lattice. A larger B96N96 octahedral cage formed from B24N24 by adding sufficient hexagons to isolate all squares is not very favorable energetically. The squares protrude noticeably from its otherwise round surface.

description: We study the effect of the COVID-19 pandemic and the associated government measures on individual mobility choices in Switzerland. Our data is based on over 1,000 people for which we observe all trips during eight weeks before the pandemic and again for up to 6 months after its onset. We find an overall reduction of travel distances by 60 percent, followed by a gradual recovery during the subsequent reopening of the economy. Whereas driving distances have almost completely recovered, public transport remains under-used. The introduction of a requirement to wear a mask in public transport had no measurable impact on ridership. We study the heterogeneity of the individual travel response to the pandemic and find that it varies along socio-economic dimensions such as education and household size, with mobility tool ownership, and with personal values and lifestyles.

description: We propose a novel system SwarmCloak for landing of a fleet of four flying robots on the human arms using light-sensitive landing pads with vibrotactile feedback. We developed two types of wearable tactile displays with vibromotors which are activated by the light emitted from the LED array at the bottom of quadcopters. In a user study, participants were asked to adjust the position of the arms to land up to two drones, having only visual feedback, only tactile feedback or visual-tactile feedback. The experiment revealed that when the number of drones increases, tactile feedback plays a more important role in accurate landing and operator's convenience. An important finding is that the best landing performance is achieved with the combination of tactile and visual feedback. The proposed technology could have a strong impact on the human-swarm interaction, providing a new level of intuitiveness and engagement into the swarm deployment just right from the skin surface.

description: Traditionally, the transmission gear for cutter adopts gear mechanism combined with planar crank joystick mechanism. In line with this drawback, this paper presents a practical spatial linkage mechanism. Through three-dimensional modeling and kinematic analysis, it obtains the equation of motion for output displacement, speed and acceleration. Besides, it gets the kinetic curve through emulation. The emulation results indicate that RCSR mechanism can realize smooth and stable output of cutter, laying a foundation for future dimensional synthesis of the mechanism.

description: The parity of the number of elementary excitations present in a quantum system provides important insights into its physical properties. Parity measurements are used, for example, to tomographically reconstruct quantum states or to determine if a decay of an excitation has occurred, information which can be used for quantum error correction in computation or communication protocols. Here we demonstrate a versatile parity detector for propagating microwaves, which distinguishes between radiation fields containing an even or odd number n of photons, both in a single-shot measurement and without perturbing the parity of the detected field. We showcase applications of the detector for direct Wigner tomography of propagating microwaves and heralded generation of Schrödinger cat states. This parity detection scheme is applicable over a broad frequency range and may prove useful, for example, for heralded or fault-tolerant quantum communication protocols.

description: Based on the quarterly economic, social and financial development data of 39 poverty-stricken counties in Henan Province during 2016-2018, this paper utilized the entropy-based TOPSIS method to objectively measure the rural revitalization index, and then built the quantile regression model to study the effects of various elements of inclusive finance on different stages of rural revitalization. Research results show that industrial development, agricultural modernization, targeted poverty alleviation, endogenous demand, and rural governance are the main points of inclusive finance in poverty-stricken areas to support rural revitalization; the rural revitalization index indicates that compared with the Dabie Mountain area and the non-contiguous poverty-stricken areas, the rural revitalization of the Qinba Mountain area is slower; for inclusive finance supporting rural revitalization, it is necessary to bring into play the role of monetary policy tools in re-lending, functions of credit in supporting industrial development, and role of insurance in risk protection; furthermore, inclusive finance solves problems such as the diminishing marginal effect of physical machinery investment in rural revitalization support, financial support for the coordinated development of small farmers and new agricultural business entities, financial support for the development of the entire industry chain, and the "siphon effect" of capital.

description: Intercropping is a very effective cultivation method in the agricultural production with a long history. The use of intercropping to build a niche complementary crop community can not only enhance the stability of farmland ecosystem and the resistance of crop community to environmental stress but also reduce the damage of diseases, insect pests, environmental pollution and improve the efficiency of resource use to finally achieve high and stable yield of crop community. By collecting the intercropping researches at home and abroad, this thesis describes the impact of intercropping on crop nitrogen fixation and nitrogen transfer, accumulation and distribution of soil nitrate nitrogen, soil microorganism, crop diseases and insect pests, ventilation and light transmission, quality, yield and nutrient absorption, draws a conclusion on intercropping advantages and points out the sections requiring further study in the future.
Yukawa Hierarchies From Extra Dimensions With Small FCNC

description: We investigate a class of extra dimensional models where all of the Standard Model fermions are localized to a single fixed point in an $S_1/Z_2$ orbifold, and each species is localized with an exponential wavefunction with a different width. We show that this naturally generates Yukawa hierarchies of the size present in the Standard Model, and we find a set of model parameters that reproduces the observed masses and mixings to experimental accuracy. In addition, the dominant constraints, arising from flavor changing neutral currents, are shown to restrict the compactification scale to be $1/R \ge 2-5 \tev$, which is a much less stringent constraint than in similar extra dimensional models of the Yukawa hierarchy.

description: We estimate the efficiency of groundwater use in cotton production in the Punjab province of Pakistan. We use a survey data of 189 cotton producers comprising 98 tube-well owners and 91 water buyers in order to get the differential impact of tube-well ownership on groundwater use efficiency. We use data envelopment analysis to compute the technical, scale, cost and allocative efficiencies for tube-well owners and water buyers relative to a meta-frontier and groupfrontiers. The DEA sub-vector and slack-based models are used to compute groundwater use efficiency. The results indicate low levels of technical inefficiencies with water buyers being more inefficient relative to tube-well owners. However, groundwater use inefficiency is more pronounced than the respective technical efficiency. The sub-vector and slack-based estimates are highly correlated suggesting the robustness of the results. The results on returns to scale indicate that the majority of cotton growers are operating at increasing returns to scale, suggesting that efficiency can be improved by expanding the scale of operation. We use a second-stage bootstrap truncated regression to investigate the factors that influence technical efficiency and groundwater use efficiency. We find that the level of education, seed quality and extension services have positive significant impacts on technical and groundwater use efficiency. We suggest that knowledge of crop water requirements and the use of improved crop varieties can play role in improving the efficiency of groundwater use.

description: We calculate the survival probability P_S(t) up to time t of a tracer particle moving along a deterministic trajectory in a continuous d-dimensional space in the presence of diffusing but mutually noninteracting traps. In particular, for a tracer particle moving ballistically with a constant velocity c, we obtain an exact expression for P_S(t), valid for all t, for d<2. For d \geq 2, we obtain the leading asymptotic behavior of P_S(t) for large t. In all cases, P_S(t) decays exponentially for large t, P_S(t) \sim \exp(-θt). We provide an explicit exact expression for the exponent θin dimensions d \leq 2, and for the physically relevant case, d=3, as a function of the system parameters.

On the typology of motion events in Aymara

Year: 2021

description: This paper investigates the lexicalization pattern of motion events in Aymara, an Andean language spoken in Bolivia, Peru, and Chile. After providing a description of the morphosyntax of translational motion events, this study aims at a preliminary typological classification of Aymara within the framework of Talmy’s typology (Talmy 2000). With this purpose, three diagnostic tests have been used to determine the basic framing-typology of motion events. These tests consider i) the size of manner-of-motion lexicon and, more broadly, the degree of manner salience, ii) the complex-path constructions and the use of ‘plus-ground’ clauses, iii) the expression of boundary-crossing. The results of this analysis are in line with predictions of expected values according to Talmian typology, and suggest that Aymara is a predominantly satellite-framed language.

description: Significant public funds are spent on projects designed to improve environmental quality. Design and implementation of these initiatives is contingent on knowledge generated from environmental research. Funding agencies have many demands for research dollars while having limited research budgets. A prioritisation process is required for efficient and effective allocation of research funds. A review of research prioritisation literature suggests that ad hoc approaches are often used for ex ante analyses examining the value of environmental research (e.g., Delphi techniques, information gaps from literature reviews). This paper characterises environmental research prioritisation in the form of an economic decision problem, formulated using expected value of information concepts. An implicitly Bayesian modelling approach is developed with research priorities being made based on estimates of expected value of partial perfect information (EVPPI). Considerations and challenges associated with empirical implementation of EVPPI are discussed and a hypothetical example is provided to illustrate use of this approach in informing environmental research funding decisions.

A single-chord high-cadence (2 Hz) photometry dataset was obtained with the Tomo-e Gozen CMOS camera mounted on the 1.05 m Schmidt telescope at Kiso Observatory. The obtained ingress and egress data do not show any indication of atmospheric refraction and allow to set new $1σ$ and $3σ$ upper limits of 6 and 16 nbar, respectively, for the surface pressure of a pure methane atmosphere. These upper limits are lower than the saturation vapor pressure of methane at Quaoar's expected mean surface temperature ($T \sim 44$ K) and imply the absence of a $\sim$10 nbar-level global atmosphere formed by methane ice on Quaoar's surface.

The computer is based on a quantum error avoidance code that protects against a class of multiple-qubit errors. The code stores two decoherence-free logical qubits in four noisy physical qubits. The computer successfully executes Grover's search algorithm in the presence of arbitrarily strong engineered decoherence. A control computer with no decoherence protection consistently fails under the same conditions.

Random Matrices with Correlated Elements: A Model for Disorder with Interactions

description: The complicated interactions in presence of disorder lead to a correlated randomization of states. The Hamiltonian as a result behaves like a multi-parametric random matrix with correlated elements. We show that the eigenvalue correlations of these matrices can be described by the single parametric Brownian ensembles. The analogy helps us to reveal many important features of the level-statistics in interacting systems e.g. a critical point behavior different from that of non-interacting systems, the possibility of extended states even in one dimension and a universal formulation of level correlations.

description: In today's rapidly informed age, it is very important to interest the student in science, especially in fiction, to educate him, to form his spiritual-ethical, educational and literary-aesthetic views from a young age. The reason is that in order to preserve the national image and spirituality of each nation, new pedagogical technologies and assignments are needed to encourage young generations to think independently, to be able to independently understand the meaning of an artistic work, to understand the ideas in the work, and to direct students to creativity. development is more relevant today than ever. This article presents examples of educational tasks that guide students to creative thinking.

description: We present the results of directional point-contact measurements in MgB_2 single crystals, in magnetic fields up to 9 T parallel to the c axis. By fitting the conductance curves of our point contacts -- showing clear Andreev-reflection features -- with a generalized Blonder-Tinkham-Klapwijk model, we were able to extract the values of the two gaps Delta_sigma and Delta_pi. The comparison of the resulting Delta_sigma(B) and Delta_pi(B) curves to the theoretical predictions of the two-band model in dirty limit, recently appeared in literature, allows the first direct test of this model and gives a clear and quantitative proof that the pi band, even in the best single crystals, is in the moderate dirty limit.

description: Spearheaded by the recent efforts to derive stochastic geophysical fluid dynamics models, we present a generic framework for introducing stochasticity into variational principles through the concept of a semi-martingale driven variational principle and constraining the component variables to be compatible with the driving semi-martingale. Within this framework and the corresponding choice of constraints, the Euler-Poincare equation can be easily deduced. We show that their corresponding deterministic counterparts are particular cases of this class of stochastic variational principles. Moreover, this is a natural framework that enables us to correctly characterize the pressure term in incompressible stochastic fluid models. Other general constraints can also be incorporated as long as they are compatible with the driving semi-martingale.

description: The dielectric properties of single-shell spherical cells with an intrinsic dielectric dispersion has been investigated. By means of the dielectric dispersion spectral representation (DDSR) for the Clausius-Mossotti (CM) factor, we express the dispersion strengths as well as the characteristic frequencies of the CM factor analytically in terms of the parameters of the cell model. These analytic expressions enable us to assess the influence of various model parameters on the electrokinetics of cells. Various interesting behaviours have been reported. We extend our considerations to a more realistic cell model with a graded core, which can have spatial gradients in the conductivity and/or permittivity. To this end, we address the effects of a graded profile in a small-gradient expansion in the framework of DDSR.

description: The Japanese TV program 'Drama A' is a drama broadcast from October to December 2016. The audience rating was sluggish, but this drama marked a high audience rating in 2016. Since it was popular from the middle, and it was speculated that there was a part related to social media in the popularity, we considered existing research methods as a case study. In this paper, we used a mathematical model of the hit phenomenon to examine the impact of audience assessment from social media from a sociophysical perspective. We got the same consideration as the audience rating per minute of video research. This paper is IEEE BIGDATA2018's Revised paper(Consideration on TV audience rating and influence of social media).

Performance/Media/Documentation... Thinking Beyond Dichotomies
Creators: name: Cecchi, Alessandro
Publisher: name: Sound Stage Screen
Year: 2021

description: The philosophical and general cultural contribution of Philip Auslander’s work to music, media, and the arts considered as performance is the radical, critical, and self-critical questioning of cultural dichotomies that often trap our thoughts exactly when they seem to help us think more clearly. Intervewed by Alessandro Cecchi, Auslander reflects on the exploration of the “continuum” between sound and vision, technique and technology, performance and media, music and the arts considered in their continuously and mutually changing relationships. Philip Auslander is a Professor of Performance Studies and Popular Musicology in the School of Literature, Media, and Communication of the Georgia Institute of Technology (Atlanta, Georgia, USA). He is the author of numerous scholarly articles and seven books, including Presence and Resistance: Postmodernism and Cultural Politics in Contemporary American Performance (University of Michigan Press, 1992), From Acting to Performance: Essays in Modernism and Postmodernism (Routledge, 1997), Liveness: Performance in a Mediatized Culture (Routledge, 1999; 2nd ed. 2008),Performing Glam Rock: Gender and Theatricality in Popular Music (University of Michigan Press, 2006), Reactivations: Essays on Performance and Its Documentation (University of Michigan Press, 2018), and In Concert: Performing Musical Persona (University of Michigan Press, 2021). In addition to his scholarly work on performance and music, Prof. Auslander has written art criticism for ArtForum and other publications and regularly contributes essays to exhibition catalogs for museums in Europe and North America, including Tate Modern, The Whitney Museum of American Art, the Migros Museum, and the Walker Art Center. He is also a screen actor and writer. “Dr. Blues,” a short film Auslander wrote, produced, and acted in, premiered at the Peachtree Village International Film Festival in Atlanta in October of 2019.

description: We introduce a nonsymmetric real matrix which contains all the information that the usual Hermitian density matrix does, and which has exactly the same tensor product structure. The properties of this matrix are analyzed in detail in the case of multi-qubit (e.g. spin = 1/2) systems, where the transformation between the real and Hermitian density matrices is given explicitly as an operator sum, and used to convert the essential equations of the density matrix formalism into the real domain.

Kinetic theory of the electron strahl in the solar wind

description: We develop a kinetic theory for {the electron strahl, a beam of energetic electrons which propagate} from the sun along the Parker-spiral-shaped magnetic field lines. By assuming a Maxwellian electron distribution function in the near-sun region where the plasma is collisional, we derive the strahl distribution function at larger heliospheric distances. We consider the two most important mechanisms that broaden the strahl: Coulomb collisions and interactions with oblique ambient whistler turbulence (anomalous diffusion). We propose that the energy regimes where these mechanisms are important are separated by an approximate threshold, ${\cal E}_c$; for the electron kinetic energies ${\cal E}{\cal E}_c$ by interactions with the whistlers. The Coulomb broadening decreases as the electron energy increases; the whistler-dominated broadening, on the contrary, increases with energy and it can lead to efficient isotropization of energetic electrons and to formation of the electron halo. The threshold energy ${\cal E}_c$ is relatively high in the regions closer to the sun, and it gradually decreases with the distance, implying that the anomalous diffusion becomes progressively more important at large heliospheric distances. At $1$ AU, we estimate the energy threshold to be about ${\cal E}_c\sim 200\,{\rm eV}$.

description: We present electro-photometric UBV and high-speed U-band flickering observations of the recurrent nova T CrB during a period when its U brightness varies by more than 2 mag. The V band is dominated by the ellipsoidal variability of the red giant, however, the variability of the hot component also causes 0.15 mag variations in V. We define a set of parameters which characterise the flickering. The Fourier spectra of all 27 nights are similar to each other. The power spectral density of the variations has a power law component (f^{-1.46} on average). We do not detect a dependence of the Fourier spectra and autocorrelation function on the brightness of the object. Having subtracted the contribution of the red giant, we show that the flickering amplitude correlates with the average flux of the accreting component. A comparison with CH Cyg and MWC 560 indicates that the flickering of T CrB is more stable (at least during the time of our observations), than that in the jet-ejecting symbiotic stars. The data are available in electronic form from the authors.

Global distribution of the rooting zone water storage capacity reflects plant adaptation to the environment

description: The rooting zone water storage capacity (S0) extends from the soil surface to the weathered bedrock (the Critical Zone) and determines land-atmosphere exchange during dry periods. Despite its importance to land-surface modeling, variations of S0 across space are largely unknown as they cannot be observed directly. We developed a method to diagnose global variations of S0 from the relationship between vegetation activity (measured by sun-induced fluorescence and by the evaporative fraction) and the cumulative water deficit (CWD). We then show that spatial variations in S0 can be predicted from the assumption that plants are adapted to sustain CWD extremes occurring with a return period that is related to the life form of dominant plants and the large-scale topographical setting. Predicted biome-level S0 distributions, translated to an apparent rooting depth (zr) by accounting for soil texture, are consistent with observations from a comprehensive zr dataset. Large spatial variations in S0 across the globe reflect adaptation of zr to the hydroclimate and topography and implies large heterogeneity in the sensitivity of vegetation activity to drought. The magnitude of S0 inferred for most of the Earth’s vegetated regions and particularly for those with a large seasonality in their hydroclimate indicates an important role for plant access to water stored at depth - beyond the soil layers commonly considered in land-surface models.
Sparse Sampling for Fast Quasiparticle Interference Mapping

description: Scanning tunneling microscopy (STM) is a notoriously slow technique; Data-recording is serial which renders complex measurement tasks, such as quasiparticle interference (QPI) mapping, impractical. However, QPI would provide insight into band-structure details of quantum materials which can be inaccessible to angle-resolved photoemission spectroscopy. Here we use compressed sensing (CS) to fundamentally speed-up QPI mapping. We reliably recover the QPI information from a fraction of the usual local density of state measurements. The requirement of CS is naturally fulfilled for QPI, since CS relies on sparsity in a vector domain, here given by few nonzero coefficients in Fourier space. We exemplify CS on a simulated Cu(111) surface using random sampling of constant and varying probability density. We further simplify the motion of the STM tip through an open traveling salesman's problem for greater efficiency. We expect that the implications of our CS approach will be transformative for the exploration of 2D quantum materials.
