description: Deiroptyx occulta Species Group
 Diagnosis. —  Support for this group is provided by 147 apomorphies including 25 morphological and 122 molecular ones. There are 18 unequivocal morphological apomorphies: maximum male snout-to-vent length decreased (1: k to c); head length decreased (4: q to l); preoccipital scales usually absent (33: a to g); scales in supraorbital disk about equal in size (41: 0 to 4); modal number of enlarged sublabial scales zero (44: 2 to 0); modal number of postxiphisternal inscriptional ribs 5:0 (47: 6 to 3); modal number of sternal ribs two (48: 1 to 0); interclavicle T-shaped (50: a to z); modal number of presacral vertebrae 23 (51: 0 to 1); modal number of caudal vertebrae anterior to first autotomic vertebra five (53: 4 to 2); supraoccipital crest with distinct lateral processes (55: 0 to 1); prefrontal usually present (62: a to g); prefrontal separated from nasal by frontal and maxilla (63: a to z); frontal separated from nasal by open gap (64: 0 to 1); epipterygoid usually separated from parietal (70: a to w); posteriormost tooth usually completely anterior to mylohyoid foramen (81: n to x); angular process of articular reduced or absent (82: a to z); anteriormost aspect of posterior border of dentary within mandibular fossa (84: n to z); no splenial (85: 0 to 1); and coronoid labial process absent (88: z to a). There are 70 unequivocal molecular apomorphies (see Appendix II).
 Definition. —  The single species placed in this species group is a relatively small form (snout-to-vent length in adult males to 42 mm and to 40 mm in adult females) distinctive in the following combination of features: 1) dorsal surface of skull smooth; 2) dewlap large in both sexes, base extending beyond axilla onto venter; 3) no splenial; 4) dorsal scales, small, round, and smooth; 5) ventral scales cycloid, juxtaposed and in transverse rows, larger than dorsal scales; 6) Type I karyotype: 2N = 36 (24M, 24m), N.F. = 48; no sexual heteromorphism.
 Content. —  A single species, Deiroptyx occulta, is referred to this species group (see Appendix III).
 Distribution. —  Puerto Rico (Fig. 13).
 Remarks. —  We are accepting the topology of the molecular tree that places D. occulta as the basal sister group to all other Deiroptyx. We think that its position on the combined tree is an anomaly in which the morphological peculiarities of this lizard overrode the molecular signal.

description: We study the structural, magnetic, transport and electronic properties of LaCoO$_3$ with Sr/Nb co-substitution, i.e., La$_{(1-2x)}$Sr$_{2x}$Co$_{(1-x)}$Nb$_{x}$O$_3$ using x-ray and neutron diffraction, dc and ac-magnetization, neutron depolarization, dc-resistivity and photoemission measurements. The powder x-ray and neutron diffraction data were fitted well with the rhombohedral crystal symmetry (space group \textit{R$\bar{3}$c}) in Rietveld refinement analysis. The calculated effective magnetic moment ($\approx$3.85~$μ_B$) and average spin ($\approx$1.5) of Co ions from the analysis of magnetic susceptibility data are consistent with 3+ state of Co ions in intermediate-spin (IS) and high-spin (HS) states in the ratio of $\approx$50:50, i.e., spin-state of Co$^{3+}$ is preserved at least up to $x=$ 0.1 sample. Interestingly, the magnetization values were significantly increased with respect to the $x=$ 0 sample, and the M-H curves show non-saturated behavior up to an applied maximum magnetic field of $\pm$70 kOe. The ac-susceptibility data show a shift in the freezing temperature with excitation frequency and the detailed analysis confirm the slower dynamics and a non-zero value of the Vogel-Fulcher temperature T$_0$, which suggests for the cluster spin glass. The unusual magnetic behavior indicates the presence of complex magnetic interactions at low temperatures. The dc-resistivity measurements show the insulating nature in all the samples. However, relatively large density of states $\approx$10$^{22}$ eV$^{-1}$cm$^{-3}$ and low activation energy $\approx$130~meV are found in $x=$ 0.05 sample. Using x-ray photoemission spectroscopy, we study the core-level spectra of La 3$d$, Co 2$p$, Sr 3$d$, and Nb 3$d$ to confirm the valence state.

description: We consider many-body effects on particle scattering in one, two and three dimensional Bose gases. We show that at zero temperature these effects can be modelled by the simpler two-body T-matrix evaluated off the energy shell. This is important in 1D and 2D because the two-body T-matrix vanishes at zero energy and so mean-field effects on particle energies must be taken into account to obtain a self-consistent treatment of low energy collisions. Using the off-shell two-body T-matrix we obtain the energy and density dependence of the effective interaction in 1D and 2D and the appropriate Gross-Pitaevskii equations for these dimensions. We present numerical solutions of the Gross-Pitaevskii equation for a 2D condensate of hard-sphere bosons in a trap. We find that the interaction strength is much greater in 2D than for a 3D gas with the same hard-sphere radius. The Thomas-Fermi regime is therefore approached at lower condensate populations and the energy required to create vortices is lowered compared to the 3D case.

description: Agricultural production in the United States, through its intensive use of nitrogen fertilizer, has contributed to nitrate accumulation in groundwater. Concern over this contamination has led to increased public interest in schemes designed to reduce nitrate leachate from agricultural lands. This research compares the costs of alternative regulatory policies in an area of the Com Belt with those for an area of the Northeast. The bioeconomic models of agricultural production and nitrate leaching are used to compare alternative policy instruments. They include soil-specific leaching and productivity characteristics, variables for management response, the dynamic nature of nitrogen movement through the soil, and the stochastic influence of precipitation on both net farm revenue and nitrate leaching. The models include state variables for nitrogen levels in the crop root zone and control variables for nitrogen fertilizer application and crop rotations. Nitrate leaching is restricted using a chance constraint, thus in some sense minimizing the probability of worst-case leaching scenarios. Six alternative regulatory policies are compared empirically in two specific regions: Boone County in Iowa and Genesee and Wyoming Counties in New York. The policies, which are designed to reduce expected annual leachate by 10% and 25% in each region, include a tax on nitrogen fertilizer, quantity restrictions on both fertilizer and leachate, and three forms of leachate permits. The three permit schemes are permits sold by a regulatory agency at a fixed price, permits auctioned by a regulatory agency, and tradable permits initially allocated at no cost to farmers with the initial distribution based on historic leachate levels. The empirical analysis shows that costs of achieving a regional reduction in leachate are greater in Iowa than in New York. Within a region, the net cost of reducing regional leachate (the net cost being the cost to farmers less any public revenues generated) is the least under the three permit schemes, although the costs of other policies are generally not substantially greater. The ranking of the net costs of these other policies differs by region and by the percent reduction in leachate. While net costs are the least under all three permit schemes, two of the three schemes result in substantial transfers of money from the farming community to the public treasury. In addition, a case is made for using a tradable permit scheme in targeted areas in and around major groundwater sources that are highly susceptible to contamination.

Physics of Collisionless GRB Shocks and Their Radiation Properties
Creators: name: Medvedev, Mikhail V.
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a theory of ultrarelativistic collisionless shocks based on the relativistic kinetic two-stream instability. We demonstrate that the shock front is unstable to the generation of small-scale, randomly tangled magnetic fields. These fields are strong enough to scatter the energetic incoming (in the shock frame) protons and electrons over pitch angle and, therefore, to convert their kinetic energy of bulk motion into heat with very high efficiency. This validates the use of MHD approximation and the shock jump conditions in particular. The effective collisions are also necessary for the diffusive Fermi acceleration of electrons to operate and produce an observed power-law. Finally, these strong (sub-equipartition) magnetic fields are also required for the efficient synchrotron-type radiation emission from the shocks. The predicted magnetic fields have an impact on polarization properties of the observed radiation (e.g., a linear polarization from a jet-like ejecta and polarization scintillations in radio for a spherical one) and on its spectrum. We present an analytical theory of jitter radiation, which is emitted when the magnetic field is correlated on scales smaller then the gyration (Larmor) radius of the accelerated electrons. A composite jitter+synchrotron model of GRB $γ$-ray emission from internal shocks is capable of resolving many puzzles of GRB spectra, such as the violation of the ``line of death'', sharp spectral breaks, and multiple spectral components seen in some bursts (good examples are GRB910503, GRB910402, etc.). We stress that simultaneous detection of both spectral components opens a way to a precise diagnostics of the conditions in GRB shocks. We also discuss the relation of our results to other systems, such as internal shocks in blazars, radio lobes, and supernova shocks.

description: We present a new characterization of termination of general logic programs. Most existing termination analysis approaches rely on some static information about the structure of the source code of a logic program, such as modes/types, norms/level mappings, models/interargument relations, and the like. We propose a dynamic approach which employs some key dynamic features of an infinite (generalized) SLDNF-derivation, such as repetition of selected subgoals and recursive increase in term size. We also introduce a new formulation of SLDNF-trees, called generalized SLDNF-trees. Generalized SLDNF-trees deal with negative subgoals in the same way as Prolog and exist for any general logic programs.

description: For many stochastic processes, the probability $S(t)$ of not-having reached a target in unbounded space up to time $t$ follows a slow algebraic decay at long times, $S(t)\sim S_0/t^θ$. This is typically the case of symmetric compact (i.e. recurrent) random walks. While the persistence exponent $θ$ has been studied at length, the prefactor $S_0$, which is quantitatively essential, remains poorly characterized, especially for non-Markovian processes. Here we derive explicit expressions for $S_0$ for a compact random walk in unbounded space by establishing an analytic relation with the mean first-passage time of the same random walk in a large confining volume. Our analytical results for $S_0$ are in good agreement with numerical simulations, even for strongly correlated processes such as Fractional Brownian Motion, and thus provide a refined understanding of the statistics of longest first-passage events in unbounded space.

description: Cells use genetic switches to shift between alternate stable gene expression states, e.g., to adapt to new environments or to follow a developmental pathway. Conceptually, these stable phenotypes can be considered as attractive states on an epigenetic landscape with phenotypic changes being transitions between states. Measuring these transitions is challenging because they are both very rare in the absence of appropriate signals and very fast. As such, it has proven difficult to experimentally map the epigenetic landscapes that are widely believed to underly developmental networks. Here, we introduce a new nonequilibrium perturbation method to help reconstruct a regulatory network's epigenetic landscape. We derive the mathematical theory needed and then use the method on simulated data to reconstruct the landscapes. Our results show that with a relatively small number of perturbation experiments it is possible to recover an accurate representation of the true epigenetic landscape. We propose that our theory provides a general method by which epigenetic landscapes can be studied. Finally, our theory suggests that the total perturbation impulse required to induce a switch between metastable states is a fundamental quantity in developmental dynamics.

description: Time-reversal and inversion breaking in the pseudogap region of the cuprate compounds have been proposed and detected by means of ARPES in the compound Bi-2212. Given the implication of the effect in the physics of the cuprate superconductors, it is important to check the conclusions through quite independent experimental techniques. We show how time-reversal and inversion breaking may be revealed in the Cuprates through resonant x-ray scattering and through non-reciprocal or magnetochiral dichroism.

description: We present adaptive optics JHKs imaging observations of three main-sequence late B-type stars listed in the Lindroos Catalogue: HD123445, HD127971 and HD129791. Given their spectral types, these stars should not be X-ray emitters. However, they have been detected by ROSAT and their X-ray emission has been attributed to possible unresolved late-type companions. We have carried out near-IR observations with ADONIS at the ESO 3.6m but have not detected any late-type companions close to HD127971 and HD129791. This result leads us to conclude that either (i) they are spectroscopic binaries with unresolved low-mass companions, or (ii) they are intrinsic X-ray emitters. While the former case would be consistent with the reported high multiplicity of early-type (A and B) stars, the latter would yield a revision of stellar activity theories which do not predict X-ray emission from these stars. On the other hand, HD123445 does indeed show visual companions, namely an apparent subarcsecond faint (Ks=10mag) binary system at a projected separation of 5" from the late-B type star. The JHKs magnitudes and colors of the components are consistent with a pair of Pre Main Sequence (PMS) K-type stars at 140 pc, i.e. possible members of the Upper Centaurus Lupus association. In this case the reported X-ray emission can be ascribed to the new binary system. Nevertheless, spectroscopy is required to confirm the possible PMS nature of the pair.

description: Strip intercropping of corn and soybeans can result in improved corn yields but at the cost of reduced soybean yields. Additionally, machinery and labor costs may be increased with strip cropping due to the use of smaller equipment. We present a systematic comparison of the relative net revenue differences for a large-scale corn-soybean operation under conventional and strip intercropping production practices. Although strip intercropping resulted in greater gross receipts than monoculture within a field, costs of machine ownership and operation and labor were much higher, resulting in lower net returns.

description: In the cell, proteins fold and perform complex functions through global structural rearrangements. Function requires a protein to be at the brink of stability to be susceptible to small environmental fluctuations, yet stable enough to maintain structural integrity. These apparently conflicting behaviors are exhibited by systems near a critical point, where distinct phases merge $-$ a concept beyond previous studies indicating proteins have a well-defined folded/unfolded phase boundary in the pressure-temperature plane. Here, by modeling the protein phosphoglycerate kinase (PGK) on the temperature (T), pressure (P), and crowding volume-fraction ($ϕ$) phase diagram, we demonstrate a critical transition where phases merge, and PGK exhibits large structural fluctuations. Above the critical temperature (Tc), the difference between the intermediate and unfolded phases disappears. When $ϕ$ increases, the Tc moves to a lower T. We verify the calculations with experiments mapping the T-P-$ϕ$ space, which likewise reveal a critical point at 305 K and 170 MPa that moves to a lower T as $ϕ$ increases. Crowding places PGK near a critical line in its natural parameter space, where large conformational changes can occur without costly free energy barriers. Specific structures are proposed for each phase based on simulation.

description: We analyze a bifurcation phenomenon associated with critical gravitational collapse in a family of self-gravitating SU(2) $σ$-models. As the dimensionless coupling constant decreases, the critical solution changes from discretely self-similar (DSS) to continuously self-similar (CSS). Numerical results provide evidence for a bifurcation which is analogous to a heteroclinic loop bifurcation in dynamical systems, where two fixed points (CSS) collide with a limit cycle (DSS) in phase space as the coupling constant tends to a critical value.

description: Globally competitive economies require well-prepared and appropriately skilled workforces. Achieving this outcome is facilitated by adoption of multimodal, novel network strategies that bring together human capital, technological, entrepreneurial social and educational resources to generate innovative economic solutions. Developing suitable workforces is impacted by: 1) recognition of diversity along a number of gradients: individual characteristics, perspectives, and capacities; 2) awareness of participation gaps on both the demand and supply side of the equation; 3) development of new partnerships with intermediaries (analog/human, in-person, virtual and platform-centric); 4) adoption of mixed-sector policy approaches to achieve well-prepared workforces; 5) reconceptualization of “work” matching resources to the needs of employers and institutions.A literature review and baseline assessment suggest the need for a more robust understanding of: 1) flow of knowledge across regional networks; 2) the role and impact of inter-actor relationships that can help promote the targeted development of synergistic partnerships in emerging networks that may be more likely to yield results; 3) the impact of network intermediaries in regional innovation, 4) the impact of policy innovation as a network facilitator.This paper presents a comparative case study of innovation networks in the U.S. and Canada focused on existing islands of innovation and innovative metropolises. Key factors included an examination of the role of intermediaries (both institutions and platforms), specifically, an exploration of how innovation networks adapt to technological changes (such as AI driven work), and identification of variables for a broader survey of policy instruments and actors addressing workforce and innovation efforts.

description: In two dimensions the Gross-Pitaevskii equation for a cold, dilute gas of bosons has an energy dependent coupling parameter describing particle interactions. We present numerical solutions of this equation for bosons in harmonic traps and show that the results can be quite sensitive to the precise form of the coupling parameter that is used.

description: Analyses of recent helioseismic data indicate that the dynamical regimes at the base of the convection zone can be different from those observed at the top, having either significantly shorter periods or non--periodic behaviour. Recently spatiotemporal fragmentation/bifurcation has been proposed as a dynamical mechanism to account for the multi-mode behaviour that is possibly observed in the solar convection zone, without requiring separate physical mechanisms with different time scales at different depths. Here we study the robustness of this mechanism with respect to changes to the zero order rotation profile, motivated by the uncertainties of and differences between the various reductions of the helioseimic data. We find that spatiotemporal fragmentation is a common feature of the reductions investigated

Using Solvency Ratios to Predict Future Profitability

Subjects: Agricultural and Food Policy

description: Solvency ratios are normally used as an indicator of the long-term viability of the farm business. Farms with high leverage have a greater likelihood of going bankrupt. Bankruptcy occurs because a farm loses its equity. However, for a farm to lose equity, it must generate negative profits or family living withdrawals must exceed profits and any equity increases. In either case, low profitability is likely a major factor in a farm losing equity. This might imply that highly leveraged farms, which pay more in interest expense, are earning less profit than those farms without debt. Thus it might be possible to predict future profitability based on solvency ratios. This paper tests that hypothesis but finds a naïve model of looking at past profit to predict future profits works better than using solvency ratios.
Self-similar spherically symmetric solutions of the massless Einstein-Vlasov system

description: We construct the general spherically symmetric and self-similar solution of the Einstein-Vlasov system (collisionless matter coupled to general relativity) with massless particles, under certain regularity conditions. Such solutions have a curvature singularity by construction, and their initial data on a Cauchy surface to the past of the singularity can be chosen to have compact support in momentum space. They can also be truncated at large radius so that they have compact support in space, while retaining self-similarity in a central region that includes the singularity. However, the Vlasov distribution function can not be bounded. As a simpler illustration of our techniques and notation we also construct the general spherically symmetric and static solution, for both massive and massless particles.

description: A systematic investigation of the secondary metabolites of Aspergillus fumigatus MNY-14, which was isolated from the ripe leaves of Achyranthes longifolia, led to the isolation of eighteen compounds, including twelve indole diketopiperazine alkaloids (1–12), an α-pyrone meroterpenoid (13), a nortriterpenoid (14), two benzophenones (15–16), and two quinoline alkaloids (17–18). Among them, compounds 8, 17 and 18 were isolated for the first time from A. fumigatus. The chemotaxonomic significance of the secondary metabolites was discussed. Some of the isolates (6, 10, 11, 10, 15 and 16) could be used as chemical markers for strain identification of this fungus. In addition, some of the isolates showed certain antimicrobial and acetylcholinesterase inhibitory activities.
Analysis of Consumer Awareness and Preferences for Fortified Sugar in Kenya

description: Food fortification is considered as an important strategy to address micronutrient malnutrition, which is a key challenge in most developing countries. In Kenya, the National Food Security and Nutrition Policy focus on pilot efforts on food fortification. However, lack of empirical information on consumers’ awareness and preferences for fortified foods remains the barrier to the uptake of fortified foods. This study assessed the consumers’ awareness and analyzed their preferences for fortified sugar. Awareness was assessed using binary logit model while the preferences were determined through a choice experiment survey and random parameter logit (RPL) model. The study used primary data from a random sample of 350 consumers in Nairobi County (a completely urban setup), and Kakamega County (a relatively rural setup). The study found that about 55% of the households were aware of fortified sugar and that awareness levels were statistically higher for urban consumers. Results from binary logit regression showed that age of consumers, purchasing from supermarket, reading newspaper, living in urban area as well as having a child below the age of five years, were the significant factors influencing consumers’ awareness of fortified sugar. The RPL results indicated heterogeneous and high preferences for fortified sugar attributes particularly, for rural consumers. Further, an analysis of compensating surplus (CS) showed that different consumer segments were willing to pay a premium ranging from 77% to 300% (above the average price of current conventional sugar) for fortified sugar, suggesting that there is high potential for sugar fortification in Kenya. These findings offer useful insights for the development of preference-based sugar fortification programmes in Kenya. Moreover, the results would guide formulation of policies against micronutrient malnutrition in Kenya and other developing countries, with similar conditions.

description: The multiplicity, finite system size and collision energy dependencies of heat capacity ($C_V$), conformal symmetry breaking measure (CSBM) and speed of sound ($c_s$) have been investigated using ALICE data for $p+p$ collisions at $\sqrt{s}$ = 7 TeV. The aim of this study is to ascertain the possibility of formation of a thermalized medium in such collisions. We find that there is a threshold in charged particle multiplicity beyond which $C_V$, CSBM and $c_s$ attain plateau. The presence of such threshold in multiplicity is further reflected in the variation of these quantities with center-of-mass energy ($\sqrt{s_{NN}}$). In order to have a grasp on experimentally obtained results, variation of $\langle p_T \rangle$ with multiplicity has also been studied. The experimental results have been contrasted with PYTHIA8 and it is found that PYTHIA8 is inadequate to explain the features reflected in these quantities, thereby indicating the possibility of thermalization in such small system. It is also observed that the finite size effects alone cannot explain the non-extensive nature of particle spectra in $p+p$ collisions.
