This article is no longer considered valid and should not be used as a reliable source. It remains available for open access only for archival purposes.

Clarification on the Cosmological Expansion InaccuracyIn the initial version of the Past Space (PS) model, the Hubble constant value of 69 km/s/Mpc was obtained using an empirical factor that was not fully consistent with the model's base assumptions. Without this factor, the result was around 40 km/s/Mpc, which is lower than the observed ~70 km/s/Mpc. This discrepancy was due to an underestimation of the total contribution of the "past space" field to cosmic expansion, and a simplified treatment of the scaling coefficient that regulates this contribution. This issue is currently being revised — including a more accurate evaluation of this coefficient, possibly based on the three-dimensional structure or the dynamic evolution of the past space field.

It’s important to note that this inaccuracy affects only the expansion estimates. The model’s predictions for galactic rotation curves (e.g., Milky Way, Sombrero, Andromeda, M33, IC 1101) remain consistent with observational data and require no dark matter. The core concept of the PS model remains valid, and ongoing work aims to improve its agreement with cosmological observations, including the cosmic microwave background and the age of the Universe.

I warmly invite like-minded individuals interested in actively developing this theory and collaborating on its improvement.Email: shkred.a.v@gmail.com

description: The rapid expansion of U.S. agricultural exports over the past two decades has greatly enhanced the role of exports in the U.S. agricultural economy and has increased the stake of U.S. farmers in foreign economic growth and trade, and the development of foreign markets. The growth of U.S. agricultural exports has been closely related to income growth in foreign countries. This study examines the changing nature of world import demand for agricultural products, induced by economic growth and increased incomes, and its impact on and significance for (1) U.S. agriculture, (2) changes in the commodity composition of U.S. agricultural exports, (3) market shares of U.S. agricultural exports, (4) future market potential for U.S. farm products, and (5) income and export opportunities for American farmers with continued growth in world demand and agricultural trade.

description: Hydrophis caerulescens (Shaw, 1802).
 We have identified specimens of H. caerulescens from the northern part of Australia from the Australian Museum and the Queensland Museum. This species occurs in the Gulf of Carpentaria (Cogger, 1975; Cogger et al., 1983; David & Ineich, 1999; Kharin, 2004a; Redfield, Holmes, & Holmes, 1978). We therefore regard H. caerulescens as confirmed from Australian waters.

description: The "Past Space" (PS) model proposes a novel framework for galactic dynamics and cosmology, eliminating the need for dark matter and dark energy. In this preprint, we introduce a physical origin for three-dimensional space, emerging from two-dimensional fields \( \rho_{past} = \frac{2 G m}{r} \) generated by masses and modulated by time. This approach derives an effective \( 1/r^2 \) gravitational law without additional components.  

We test PS across diverse galactic systems:  - **Spiral galaxies**: Accurate predictions for rotation curves of the Milky Way (235 km/s at 10 kpc), Andromeda (230 km/s), Sombrero (NGC 4594), M33, and IC 1101 (452 km/s), matching observations without dark matter.  - **Ultra-diffuse galaxies (UDGs)**: Successful modeling of velocity dispersions for NGC 1052-DF2 (\( \sigma = 5.76 \, \text{km/s} \)) and NGC 1052-DF4 (\( \sigma = 4.76 \, \text{km/s} \)), consistent with observed values (4.2 and 5.8 km/s), where \( \Lambda \)CDM and MOND struggle.  - **Cosmological scales**: Reproduces Mercury’s perihelion precession (41.2 arcsec/century), light deflection (1.75 arcsec), Hubble parameter \( H_0 \) (69–142 km/s/Mpc at \( z = 0–0.61 \)), supervoids (~380 Mpc), and JWST data (\( z > 10 \)), estimating the Universe’s age at 18.8–23.8 billion years.  

A general relation for elliptical systems, \( \sigma = 0.429 \sqrt{G m R_e} \), is derived, adaptable via \( f(r) \) to various galaxy types. This work challenges conventional paradigms and offers a unified, testable alternative. Submitted to *General Relativity and Gravitation*.Email: shkred.a.v@gmail.com

description: Program and policy officials involved in the work of allocating and shipping food aid from donor to recipient countries should know not only how much food each recipient country requires in a given year but also when food must be delivered to each country during that year to provide maximum benefit to those in need. In addition to basic information such as planting and harvesting periods, other factors such as usual food-deficit or "hungry" periods, rainfall seasons, and customary shipping time requirements are also relevant to determining the optimal time for food aid delivery. This reference document provides such information for major staple crops in the countries of Africa.

description: To the families of geometric measures of convex bodies (the area measures of Aleksandrov-Fenchel-Jessen, the curvature measures of Federer, and the recently discovered dual curvature measures) a new family is added. The new family of geometric measures, called chord measures, arises from the study of integral geometric invariants of convex bodies. The Minkowski problems for the new measures and their logarithmic variants are proposed and attacked. When the given data is sufficiently regular, these problems are a new type of fully nonlinear partial differential equations involving dual quermassintegrals of functions. Major cases of these Minkowski problems are solved without regularity assumptions.

The generalization extends this to dualization with respect to measures modified by arbitrary sets of weight functions.

description: The geographic distribution of U.S. agricultural land acquired by foreign investors between 1980 and 1982 differed significantly from the distribution of land purchased prior to 1980. Examination by county and district of the number of parcels expected, based upon the distribution of land purchased prior to 1980, and the observed number of parcels acquired during 1980-82 indicate locations where foreign investment deviated from expectations under the hypothesis that foreign investment follows a stable geographic pattern. Analysis of the variation in distributions suggests that factors such as the activities of real estate agents and monetary exchange rates influence the location and timing of foreign investment.

description: We present BIMA two-field mosaic CO(1-0) images of the Taffy galaxies (UGC 12914/15), which show the distinct taffy-like radio continuum emission bridging the two spiral disks. Large amounts of molecular gas (1.4 x 10^{10} Msun, using the standard Galactic CO-to-H$_2$ conversion applicable to Galactic disk giant molecular clouds [GMCs]) were clearly detected throughout the taffy bridge between the two galaxies, which, as in the more extreme case of HI, presumably results from a head-on collision between the two galaxies. The highest CO concentration between the two galaxies corresponds to the H_alpha source in the taffy bridge near the intruder galaxy UGC 12915. This HII region is also associated with the strongest source of radio continuum in the bridge, and shows both morphological and kinematic connections to UGC 12915. The overall CO distribution of the entire system agrees well with that of the radio continuum emission, particularly in the taffy bridge. This argues for the star formation origin of a significant portion of the radio continuum emission. Compared to the HI morphology and kinematics, which are strongly distorted owing to the high-speed collision, CO better defines the orbital geometry and impact parameter of the interaction, as well as the disk properties (e.g., rotation, orientation) of the progenitor galaxies. Based on the 20cm-to-CO ratio maps, we conclude that the starburst sites are primarily located in UGC 12915 and the H_alpha source in the bridge and show that the molecular gas in the taffy bridge is forming into stars with star formation efficiency comparable to that of the target galaxy UGC 12914 and similar to that in the Galactic disk.

Hydrophis inornatus

description: Hydrophis inornatus (Gray, 1849).
 Hydrophis inornatus was described by Gray (1849) who gave the type locality “Indian Ocean” with no further information. The validity of Hydrophis inornatus as a species is doubtful and only the type specimen was recognized by Rasmussen (1989) in this taxon until Kharin and Czeblukov (2005) referred to a specimen collected in Australia (Arafura Sea). However, we have not found any other evidence to support Kharin and Czeblukov’s (2005) claim that it occurs in Australia. We find little similarity between Kharin and Czeblukov’s H. inornatus specimen (TINRO R11) and the type of H. inornatus (BMNH 1946.1.1.27). In particular, the maxillary bone shown in figure 2 of Kharin and Czeblukov (2005) is markedly different from that of the type of H. inornatus (see also Rasmussen, 1989; M. A. Smith, 1926); further the type does not have any spots on its body, unlike the specimen in Kharin and Czeblukov (2005). The specimen shown in Kharin and Czeblukov (2005) more closely resembles H. major in all the morphological characters mentioned, including the number of scale rows around neck and body, ventrals, subcaudals, number of teeth on maxillary bone and body form and colour pattern. Kharin and Czeblukov (2005) also included another specimen from Arafura Sea (NTMR897) mentioned by Cogger (1975) as a possible H. inornatus; however, this specimen differs in ventral scale count to H. inornatus (Cogger, 1975). We therefore include this species neither in the checklist nor in the list of possible Australian sea snakes. Another recent paper published new records for H. inornatus from the Arabian Sea (Kharin & Dotsenko, 2012); however, based on photos included by the authors these specimens bear little resemblance to either the specimen from Australia or the type specimen, and instead clearly resemble Hydrophis viperinus (Schmidt, 1852) based on the diagnostic characters for this species (large ventral scales in the anterior part of the body) (Kharin & Dotsenko, 2012 Figures 2 and 3).

description: It is shown that the fluctuations of the jamming coverage upon Random Sequential Adsorption ($σ_{θ_J}$), decay with the lattice size according to the power-law $σ_{θ_J} \propto L^{-1 / ν_J}$, with $ν_{J} = 2 / (2D - d_f)$, where $D$ is the dimension of the substrate and $d_{\rm f}$ is the fractal dimension of the set of sites belonging to the substrate where the RSA process actually takes place. This result is in excellent agreement with the figure recently reported by Vandewalle {\it et al} ({\it Eur. Phys. J.} B. {\bf 14}, 407 (2000)), namely $ν_J = 1.0 (1)$ for the RSA of needles with $D = 2$ and $d_f = 2$, that gives $ν_J = 1$. Furthermore, our prediction is in excellent agreement with different previous numerical results. The derived relationships are also confirmed by means of extensive numerical simulations applied to the RSA of dimers on both stochastic and deterministic fractal substrates.

description: A nationwide survey of landowners indicates that owner operators of farmland made more frequent capital expenditures for conservation, land clearing, and drainage than nonoperator owners. This result applies to individual and family owners as well as to nonfamily partnerships and corporations. Retired owners made capital expenditures less frequently than other nonoperator owners. Three alternatives for maintaining and increasing the productivity of rented land are: develop land enhancing technologies that are attractive to tenants; include nonoperator owners in the services offered by local, State, and Federal agencies; and develop land purchase contracts that are mutually advantageous to tenants and older landlords.

description: Objective: To understand the gaps in communication and programming at the University of British Columbia’s (UBC) recreation facilities affecting Muslim women in recreation at the undergraduate level; to determine the barriers to their participation; and to make recommendations based on this understanding in order to ultimately increase the rates of physical activity in this population. Study Design: This project recruited Muslim Women studying at UBC at the undergraduate level (n=11) to participate in semi-structured interviews and questionnaires, both with the same questions. Interview and questionnaire responses were categorized into 7 categories: varying levels of physical activity; lack of female only space; lack of hours dedicated to female only participants in existing facilities; lack of knowledge of UBC recreation facilities and programs; emphasis on academics as a barrier to participating; perception of fitness; sense of not belonging Results: From the 11 participants, four were relatively inactive, participating in less than 75 minutes; half of the recommended minutes of physical activity per week; two were moderately physically active, participating in about 100 minutes of physical activity per week; five met the weekly recommendation of 150 minutes of physical activity; three mentioned lack of female only spaces as a barrier to their participation; two mentioned lack of female designated hours in existing facilities as a barrier; one knew nothing of UBC’s recreation facilities and programs; three were mildly aware of UBC’s recreation facilities and programs; two mentioned that emphasis on schoolwork was a barrier to their participation in UBC recreation facilities and programs. Conclusion: In order to increase UBC’s Muslim Women’s engagement with recreation facilities and programs on campus, and subsequently their physical activity, we recommend that UBC employs Muslim women as fitness instructors; includes Muslim women in their marketing materials; having such marketing materials to educate Muslim women; expanding existing female only hours at existing recreation facilities; ensuring that female staff are present during such hours; adding female only spaces with appropriate equipment, as opposed to the inadequate ones currently being provided.

description: Hydrophis melanosoma Günther, 1864.
 Shuntov (1971) suggested that 19% of the trawled specimens from shoal waters of the northwest coast of Australian belong to Hydrophis melanosoma. This claim was cited by several subsequent authors (e.g. Cogger, 1975; Cogger et al., 1983; Minton, 1975), although Cogger (1992) considered the presence of H. melanosoma in Australian waters as “uncertain”. The identifications by Shuntov lacks validation by any specimen of H. melanosoma having been collected or reported from this area since. Shuntov’s identification, in our opinion, was incorrect. We therefore exclude H. melanosoma from the checklist and the list of possible Australian sea snakes.

description: We show how entropy balancing can be used for transporting experimental treatment effects from a trial population onto a target population. This method is doubly-robust in the sense that if either the outcome model or the probability of trial participation is correctly specified, then the estimate of the target population average treatment effect is consistent. Furthermore, we only require the sample moments of the effect modifiers drawn from the target population to consistently estimate the target population average treatment effect. We compared the finite-sample performance of entropy balancing with several alternative methods for transporting treatment effects between populations. Entropy balancing techniques are efficient and robust to violations of model misspecification. We also examine the results of our proposed method in an applied analysis of the Action to Control Cardiovascular Risk in Diabetes Blood Pressure (ACCORD-BP) trial transported to a sample of US adults with diabetes taken from the National Health and Nutrition Examination Survey (NHANES) cohort.

Combining WMAP and SDSS Quasar Data on Reionization Constrains Cosmological Parameters and the Star Formation Efficiency

description: We present constraints on cosmological and star formation parameters based on combining observations of the Wilkinson Microwave Anisotropy Probe (WMAP) and high-redshift quasars from the Sloan Digital Sky Survey (SDSS). We use a semi-analytic model for reionization (Chiu and Ostriker 2000) that takes into account a number of important physical processes both within collapsing halos and in the intergalactic medium. Assuming that the efficiency of producing UV photons per baryon is constant, we derive a constraint of the form sigma_8 Omega_0^0.5~0.33 in a flat, Lambda-dominated universe with h=0.72, n=0.99, and Omega_b h^2=0.024. However, the calculated optical depth to electron scattering of tau_es~0.06 is well below the value found by WMAP of 0.17+/-(0.04~0.07) (Spergel et al 2003). Since the WMAP constraints on tau_es are somewhat degenerate with the value of the spectral index n, we then permit the primordial spectral index n to float and fix Omega_0 h^2=0.14, while normalizing the power spectrum using WMAP. In addition, we allow the UV-efficiency to have time-dependence. Combining the WMAP constraints with the quasar transmission data, our analysis then favors a model with tau_es=0.11^{+0.02}_{-0.03}, n=0.96^{+0.02}_{-0.03}$, implying sigma_8=0.83^{+0.03}_{-0.05} (95% confidence), and an effective UV-efficiency that was at least ~10x greater at z >> 6. These results indicate that the quasar and WMAP observations are consistent. If future observations confirm an optical depth to electron scattering tau_es~0.1, then it would appear that no more "exotic" sources of UV-photons, such as mini-quasars or AGNs, are necessary; but our analysis indicates that a determination of tau_es>~0.17 would require a more radical solution.

description: Some farm programs. may encourage farmers to plant crops more likely to induce erosion without encouraging soil conservation practices. If that is true, the long-term productivity of the soil may be in jeopardy. This report examines the effects of agricultural programs dealing with foreign trade, price support and production adjustment, Federal crop insurance; dairy, and Farmers Home Administration loans on erosion and presents an agenda for empirical studies of the incentives.

description: We write down three kinds of scale transformations {\tt i-iii)} on the noncommutative plane. {\tt i)} is the analogue of standard dilations on the plane, {\tt ii)} is a re-scaling of the noncommutative parameter $θ$, and {\tt iii)} is a combination of the previous two, whereby the defining relations for the noncommutative plane are preserved. The action of the three transformations is defined on gauge fields evaluated at fixed coordinates and $θ$. The transformations are obtained only up to terms which transform covariantly under gauge transformations. We give possible constraints on these terms. We show how the transformations {\tt i)} and {\tt ii)} depend on the choice of star product, and show the relation of {\tt ii)} to Seiberg-Witten transformations. Because {\tt iii)} preserves the fundamental commutation relations it is a symmetry of the algebra. One has the possibility of implementing it as a symmetry of the dynamics, as well, in noncommutative field theories where $θ$ is not fixed.

description: Purpose: Although researchers have explored parental perspectives of childhood speech and language disorders, most studies have been conducted in English-speaking countries. Little is known about parental experiences across countries, where procedures of language screening and services for language disorders differ. The authors participated in the COST Action IS1406 “Enhancing Children’s Oral Language Skills Across Europe and Beyond,” which provided an opportunity to conduct cross-country qualitative interviews with parents. The aim of this pilot study was to explore ways in which parents construed and described speech and language disorders across countries.Method: Semistructured qualitative interviews were conducted with parents from 10 families in 10 different countries. The data were analyzed using thematic analysis.Findings: The overall theme was “acknowledging parental expertise.” The parents described in detail ways how their children’s speech and language (dis)abilities had an impact on the children’s everyday life. Three subthemes were identified: impairment, disability, and changes over time.Conclusions: The findings suggest that, across a range of countries, parents construe contextualized understandings of their children’s speech and language (dis)abilities, along with the everyday functional implications of the disorders. Hence, despite not holding professional knowledge about language disorders, the voices, views, understandings, and personal experiences of parents in relation to their child’s disorder should be listened to when planning therapy services.

description: Annual adjustments of nonbasic employment in response to different hypothetical changes in basic income are described. The results illustrate findings of a regression analysis of data from 1971-79 of 30 rural counties that had experienced rapid growth. The analysis produced significant lags in annual nonbasic employment changes in relation to basic income changes. The timing of changes in nonbasic and basic sectors and consequently of population in rapidly growing local economies is a critical element in local fiscal planning.

description: Efficient sampling of satisfying formulas for circuit satisfiability (CircuitSAT), a well-known NP-complete problem, is essential in modern front-end applications for thorough testing and verification of digital circuits. Generating such samples is a hard computational problem due to the inherent complexity of digital circuits, size of the search space, and resource constraints involved in the process. Addressing these challenges has prompted the development of specialized algorithms that heavily rely on heuristics. However, these heuristic-based approaches frequently encounter scalability issues when tasked with sampling from a larger number of solutions, primarily due to their sequential nature. Different from such heuristic algorithms, we propose a novel differentiable sampler for multi-level digital circuits, called {\sc Demotic}, that utilizes gradient descent (GD) to solve the CircuitSAT problem and obtain a wide range of valid and distinct solutions. {\sc Demotic} leverages the circuit structure of the problem instance to learn valid solutions using GD by re-framing the CircuitSAT problem as a supervised multi-output regression task. This differentiable approach allows bit-wise operations to be performed independently on each element of a tensor, enabling parallel execution of learning operations, and accordingly, GPU-accelerated sampling with significant runtime improvements compared to state-of-the-art heuristic samplers. We demonstrate the superior runtime performance of {\sc Demotic} in the sampling task across various CircuitSAT instances from the ISCAS-85 benchmark suite. Specifically, {\sc Demotic} outperforms the state-of-the-art sampler by more than two orders of magnitude in most cases.

Non-diffusive transport in plasma turbulence: a fractional diffusion approach

description: Numerical evidence of non-diffusive transport in three-dimensional, resistive pressure-gradient-driven plasma turbulence is presented. It is shown that the probability density function (pdf) of test particles' radial displacements is strongly non-Gaussian and exhibits algebraic decaying tails. To model these results we propose a macroscopic transport model for the pdf based on the use of fractional derivatives in space and time, that incorporate in a unified way space-time non-locality (non-Fickian transport), non-Gaussianity, and non-diffusive scaling. The fractional diffusion model reproduces the shape, and space-time scaling of the non-Gaussian pdf of turbulent transport calculations. The model also reproduces the observed super-diffusive scaling.

description: The 1983-84 outbreak of avian influenza brought heavy losses to the. . Pennsylvania and Virginia poultry industry and caused consumers to pay nearly $350 million more for poultry and meat products. Benefits of the Federal eradication program substantially exceeded its costs by limiting'short-term losses and increases in costs from -avian influenza to producers and consumers to less than 10 percent of what •would have resulted from a - widespread - - outbreak. Government costs .for indemnities and program -administration represented only about 1 percent of the probable costs to producers and consumers of a widespread outbreak.
Theoretical estimates of the logarithmic phonon spectral moment for monatomic liquids

description: We calculate the logarithmic moment of the phonon frequency spectrum at a single density for 29 monatomic liquids using two methods, both suggested by Wallace's theory of liquid dynamics: The first method relies on liquid entropy data, the second on neutron scattering data in the crystal phase. This theory predicts that for a class of elements called ``normal melters,'' including all 29 of these materials, the two estimates should closely match, and we find that they agree to within a few percent. We also perform the same calculations for four ``anomalous melters,'' for which we expect the two estimates to differ markedly; we find that they disagree by factors almost up to three. From our results we conclude that the liquid entropy estimates of the logarithmic moment, applicable both to normal and anomalous melters, are trustworthy to a few percent, which makes them reliable for use in estimates of various liquid transport coefficients.

description: An increase in the demand for meat and slow growth in domestic meat production led to a sharp increase in meat imports in Egypt. Government intervention in the meat market increased to encourage domestic production and to prevent undue price increases. The cost to the Government of subsidizing the livestock sector increased sevenfold during 1977-82. The production response was slow because of structural problems in the industry. Egypt's dependence on imports of red meat is expected to increase from 30 percent in 1982 to about 44 percent in 1990. Growth in poultry production could reduce this dependence, and yield self-sufficiency.

description: Coagulation driven by supersonic turbulence is primarily an astrophysical problem because coagulation processes on Earth are normally associated with incompressible fluid flows at low Mach numbers, while dust aggregation in the interstellar medium (ISM) for instance is an example of the opposite regime. We study coagulation of inertial particles in compressible turbulence using high-resolution direct and shock-capturing numerical simulations with a wide range of Mach numbers from nearly incompressible to moderately supersonic. The particle dynamics is simulated by representative particles and the effects on the size distribution and coagulation rate due to increasing Mach number is explored. We show that the time evolution of particle size distribution mainly depends on the compressibility (Mach number). We find that the average coagulation kernel $\langle C_{ij}\rangle$ scales linearly with the average Mach number $\mathcal{M}_{\rm rms}$ multiplied by the combined size of the colliding particles, that is, $\langle C_{ij}\rangle \sim \langle (a_i + a_j)^3\rangle\, \mathcal{M}_{\rm rms}τ_η^{-1}$, which is qualitatively consistent with expectations from analytical estimates. A quantitative correction $\langle C_{ij}\rangle \sim \langle(a_i + a_j)^3\rangle(v_{\rm p,rms}/c_{\rm s})τ_η^{-1}$ is proposed and can serve as a benchmark for future studies. We argue that the coagulation rate $\langle R_c\rangle$ is also enhanced by compressibility-induced compaction of particles.
