Cyperus poikilostachys var. heterochrous (nelmes) reynders

description: Cyperus poikilostachys var. heterochrous  (Nelmes) Reynders, comb. nov.
 Basionym: Pycreus heterochrous Nelmes, Kew Bull. 6: 321 (1951 publ. 1952). Type:— ZAMBIA, Mwinilunga District, Matonchi Farm, 0.5 mile South of farm, 24 January 1938, E. Milne-Redhead 4309 (holotype K, isotypes BR!, P!, isotype PRE!).
 Description: —Nelmes (1951 publ. 1952: 321)
 Note: —Several specimens collected by E. Milne-Redhead in the Zambezian region were simultaneously described as new species by Nelmes, among which P. poikilostachys and P. heterochrous. The latter two species only differ in their glume colour: Pycreus poikilostachys has dark brown glumes and P. heterochrous has pale reddish brown glumes. As both are sympatric with an absence of individuals showing intermediate glume colours, Nelmes (1938) considered both colour variants as different species. Glume colour alone is now considered to be an unreliable character for species delimitation in Cyperus (Reynders 2013). In addition, as is known from classic Mendelian genetics, it is possible that different colour variants can be present in the same populations without the presence of intermediates (dominant-recessive inheritance instead of intermediate inheritance). Different colour variants of a single species are usually treated on the variety rank or below.

description: Safe operation of machine learning models requires architectures that explicitly delimit their operational ranges. We evaluate the ability of anomaly detection algorithms to provide indicators correlated with degraded model performance. By placing acceptance thresholds over such indicators, hard boundaries are formed that define the model's coverage. As a use case, we consider the extraction of exoplanetary spectra from transit light curves, specifically within the context of ESA's upcoming Ariel mission. Isolation Forests are shown to effectively identify contexts where prediction models are likely to fail. Coverage/error trade-offs are evaluated under conditions of data and concept drift. The best performance is seen when Isolation Forests model projections of the prediction model's explainability SHAP values.

description: We study domain patterns in cubic-tetragonal ferroelastics by solving numerically equations of motion derived from a Landau model of the phase transition, including dissipative stresses. Our system sizes, of up to 256^3 points, are large enough to reveal many structures observed experimentally. Most patterns found at late stages in the relaxation are multiply banded; all three tetragonal variants appear, but inequivalently. Two of the variants form broad primary bands; the third intrudes into the others to form narrow secondary bands with the hosts. On colliding with walls between the primary variants, the third either terminates or forms a chevron. The multipy banded patterns, with the two domain sizes, the chevrons and the terminations, are seen in the microscopy of zirconia and other cubic-tetragonal ferroelastics. We examine also transient structures obtained much earlier in the relaxation; these show the above features and others also observed in experiment.

description: We analyze the vacuum structure of the one-loop effective potential in the two Higgs doublet model. We find that electroweak-breaking vacuua can coexist with charge breaking ones, contradicting a theorem valid at tree-level. We perform a numerical analysis of the model and supply explicit parameter values for which charge-breaking vacuua can be the global minimum of the theory, and deeper than charge-preserving ones.

Gravitational-wave detection and parameter estimation for accreting black-hole binaries and their electromagnetic counterpart

description: We study the impact of gas accretion on the orbital evolution of black-hole binaries initially at large separation in the band of the planned Laser Interferometer Space Antenna (LISA). We focus on two sources: (i)~stellar-origin black-hole binaries~(SOBHBs) that can migrate from the LISA band to the band of ground-based gravitational-wave observatories within weeks/months; and (ii) intermediate-mass black-hole binaries~(IMBHBs) in the LISA band only. Because of the large number of observable gravitational-wave cycles, the phase evolution of these systems needs to be modeled to great accuracy to avoid biasing the estimation of the source parameters. Accretion affects the gravitational-wave phase at negative ($-4$) post-Newtonian order, and is therefore dominant for binaries at large separations. If accretion takes place at the Eddington or at super-Eddington rate, it will leave a detectable imprint on the dynamics of SOBHBs. In optimistic astrophysical scenarios, a multiwavelength strategy with LISA and a ground-based interferometer can detect about $10$ (a few) SOBHB events for which the accretion rate can be measured at $50\%$ ($10\%$) level. In all cases the sky position can be identified within much less than $0.4\,{\rm deg}^2$ uncertainty. Likewise, accretion at $\gtrsim 10\%$ ($\gtrsim 100\%$) of the Eddington rate can be measured in IMBHBs up to redshift $z\approx 0.1$ ($z\approx 0.5$), and the position of these sources can be identified within less than $0.01\,{\rm deg}^2$ uncertainty. Altogether, a detection of SOBHBs or IMBHBs would allow for targeted searches of electromagnetic counterparts to black-hole mergers in gas-rich environments with future X-ray detectors (such as Athena) and radio observatories (such as SKA).

description: Microscopic levitated objects are a promising platform for inertial sensing, testing gravity at small scales, optomechanics in the quantum regime, and large-mass superpositions. However, existing levitation techniques harnessing optical and electrical fields suffer from noise induced by elevated internal temperatures and charge noise, respectively. Meissner-based magnetic levitation circumvents both sources of decoherence but requires cryogenic environments. Here we characterize a sub-mg ferromagnetic cube levitated in an alternating-current planar magnetic Paul trap at room temperature. We show behavior in line with the Mathieu equations and quality factors of up to 2500 for the librational modes. Besides technological sensing applications, this technique sets out a path for MHz librational modes in the micron-sized particle limit, allowing for magnetic coupling to superconducting circuits and spin-based quantum systems.

description: We propose a numerical method for the solution of electromagnetic problems on axisymmetric domains, based on a combination of a spectral Fourier approximation in the azimuthal direction with an IsoGeometric Analysis (IGA) approach in the radial and axial directions. This combination allows to blend the flexibility and accuracy of IGA approaches with the advantages of a Fourier representation on axisymmetric domains. It also allows to reduce significantly the computational cost by decoupling of the computations required for each Fourier mode. We prove that the discrete approximation spaces employed functional space constitute a closed and exact de Rham sequence. Numerical simulations of relevant benchmarks confirm the high order convergence and other computational advantages of the proposed method.

description: Manually creating Planning Domain Definition Language (PDDL) descriptions is difficult, error-prone, and requires extensive expert knowledge. However, this knowledge is already embedded in engineering models and can be reused. Therefore, this contribution presents a comprehensive workflow for the automated generation of PDDL descriptions from integrated system and product models. The proposed workflow leverages Model-Based Systems Engineering (MBSE) to organize and manage system and product information, translating it automatically into PDDL syntax for planning purposes. By connecting system and product models with planning aspects, it ensures that changes in these models are quickly reflected in updated PDDL descriptions, facilitating efficient and adaptable planning processes. The workflow is validated within a use case from aircraft assembly.

description: The economy is stagnating today because everyone is waiting for someone else to restart the recovery. Consumers are deferring major purchases until job prospects are rosier. Businesses are pushing down their inventories and payrolls until their order books surge. In essence the economic fundamentals are sound, but at this point, we need a new catalyst for recovery. It is time to implement policies that directly stimulate investment including a self-financing equipment tax credit for productive equipment purchases, adjustment of Federal Reserve and Treasury market activities in order to lower bond rates, initiation of a bounty for scrapping old cars, and the channeling of a higher proportion of public funds to public investment in health, education, sCience, and advanced infrastructures.

 Basionym: Pycreus scaettae Cherm., Rev. Zool. Bot. Afr. 24: 295 (Chermezon 1933 publ. 1934).
 Lectotype (designated here):— DEMOCRATIC REPUBLIC OF CONGO, Mubeza, 1930, H. Scaetta 58M (hololectotype BR!, isolectotype K!).
 Description: — Hoenselaar et al. (2010: 296).
 Note: — Cyperus scaettae belongs to a group of species from Zambezian Africa showing thick accumulations of fibres (remains of leaf sheaths) surrounding the bases of the culms and most often inflorescences are reduced, with only a few spikelets set in a single spike. With the description of different taxa showing these characteristics (e.g. Pycreus fibrillosus, P. scaettae, Fig. 2), relatively less attention has been paid to spikelets, glume and nutlet morphology than to the striking culm bases and glume colour. In addition, communication and consultation of type material seemed to have been rather limited in the short period these taxa have been described, combined and synonymised by different authors (Chermezon 1932, 1933, 1933 publ. 1934, Kükenthal 1921, 1935 –36). Subsequently, species separations and especially synonymisations were not very clear from the beginning and several misinterpretations arose in later publications (e.g. Haines & Lye 1983). Comparision of spikelet characteristics shows Cyperus scaettae clearly differs from C. fibrillosus (Fig. 2).

description: Given its well known spectral decomposition profile, the $1$-dim harmonic oscillator potential modified by an inverse square ($1$-dim angular momentum-like) contribution works as an efficient platform for probing classical and quantum information quantifiers in the context of the phase-space Weyl-Wigner formalism. In particular, the phase-space informational content related to the canonical ensemble driven by such a {\em singular oscillator} can be quantified in terms of well established analytical structures. Considering that, on one hand, the {\em singular oscillator} produce a spectral decomposition profile equivalent to that one of the unmodified harmonic system -- in the sense that they result into identical thermodynamic statistics, even for different statistical mixtures -- on the other hand, a more complete scrutinization of their phase-space information content can capture some different aspects of the encoded information for the related quantum ensembles. Besides the identification of decoherence effects, the Wigner flow analysis is presumedly useful in identifying stable quantum configurations, according to finite temperature and interaction parameter values. Unexpectedly, our results show that the equivalence between the statistical (quantum) mechanics of the anharmonic singular oscillator and an ordinary harmonic oscillator can also be extended to the phase-space quantum purity quantifier, which is analytically computed and reproduces exactly the same quantum ensemble statistical mixture profile, which does not depend on interaction parameter values.

title: Aristotle and the search of a rational framework for biology
Creators: name: Aranda_Anzaldo, Armando
Publisher: name: Organisms. Journal of Biological Sciences
Year: 2020

description: Chance and necessity are mainstays of explanation in current biology, dominated by the neo-Darwinian outlook, a blend of the theory of evolution by natural selection with the basic tenets of population genetics. In such a framework the form of living organisms is somehow a side effect of highly contingent, historical accidents. Thus, at a difference of other sciences, biology apparently lacks theoretical principles that in a law-like fashion may explain the emergence and persistence of the characteristic forms of living organisms that paradoxically, given the current importance attributed to chance, can be grouped into organized structural typologies. Nevertheless, the present essay shows that since its origins in Aristotelian natural history, biology aimed at achieving rational, non-accidental, explanations for the wide variety of living forms endowed with characteristic behaviors that constitute the landscape of biological species.

description: Excerpts from the report Summary: This study is concerned with resales of tobacco at Maryland loose-leaf auctions after the first sales by growers, and especially with the effects of resales on the growers. Profits from the resale of Maryland tobacco are made possible by a combination of conditions. Probably the most basic of these conditions is the large amount of poorly prepared tobacco coming to market in Maryland. The second condition is market imperfections--both market fluctuations and auction conditions, such as the speed of sale and variations in light, that sometimes lead to errors in judgment of quality of tobacco. Other conditions favorable to resales on the Maryland market, especially as compared to the burley and flue-cured markets, are: Maryland has been under price supports only four times since the end of World War II; many speculators come from the burley and flue-cured areas to Maryland because, during the period between early March and mid-July , it is the only auction market open; and there is ample warehouse space, so that tobacco generally can be resold at any time.
Effect of sodium pyrophosphate and understanding microstructure of aqueous LAPONITE(R) dispersion using dissolution study

description: We investigate physical origin of ergodicity breaking in an aqueous colloidal dispersion of synthetic hectorite clay, LAPONITE(R), by performing dissolution and rheological experiments with monovalent salt and tetrasodium pyrophosphate solution. We also study the effect of interface, nitrogen and paraffin oil on the same. Dissolution experiments carried out for dispersions with both the interfaces show similar results. However, for samples with nitrogen interface, all the effects are observed to get expedited in time compared to paraffin oil interface. When kept in contact with water, 1.5 wt. % and 2.8 wt. % colloidal dispersion at pH 10 swell at small ages, while do not swell at large ages. The solution of tetrasodium pyrophosphate, interestingly, dissolves the entire colloidal dispersion samples with pH 10 irrespective of the clay concentration. Experiments carried out on colloidal dispersions prepared in water having pH 13 demonstrate no effect of water as well as sodium pyrophosphate solution on the same suggesting a possibility of the presence of negative charge on edge at that pH. We believe that all the behaviors observed for samples at pH 10 can be explained by an attractive gel microstructure formed by edge-to-face contact. Furthermore, the absence of swelling in old colloidal dispersion at pH 10 and dissolution of the same by sodium pyrophosphate solution cannot be explained by merely repulsive interactions. This behavior suggests that attractive interactions play an important role in causing ergodicity breaking in the colloidal dispersions at pH 10 at all the ages irrespective of the clay concentration. We substantiate the presence of fractal network structure formed by interparticle edge-face association using rheological tools and cryo-TEM imaging. We also conduct a comprehensive study of the effect of sodium pyrophosphate in the sol-gel transition of LAPONITE(R) dispersion.

Inertial range scaling in numerical turbulence with hyperviscosity

description: Numerical turbulence with hyperviscosity is studied and compared with direct simulations using ordinary viscosity and data from wind tunnel experiments. It is shown that the inertial range scaling is similar in all three cases. Furthermore, the bottleneck effect is approximately equally broad (about one order of magnitude) in these cases and only its height is increased in the hyperviscous case--presumably as a consequence of the steeper decent of the spectrum in the hyperviscous subrange. The mean normalized dissipation rate is found to be in agreement with both wind tunnel experiments and direct simulations. The structure function exponents agree with the She-Leveque model. Decaying turbulence with hyperviscosity still gives the usual t^{-1.25} decay law for the kinetic energy, and also the bottleneck effect is still present and about equally strong.

description: There is widespread evidence that the use of somatotropin or growth hormone to improve milk and pork production is safe. An independent committee appointed by The National Institutes of Health concluded that, "The evidence clearly indicates that the overall composition and nutritional quality of milk and meat from bST-treated cows is equal to that from untreated cows." Similarly, the FDA has concluded that the use of bST presents no increased health risk to consumers. In addition, there is compelling evidence to indicate that somatotropin poses no increased health risk to the ta rget animal. Thus, treatment of farm animals with somatotropin is not only an effective technology for increasing productive efficiency but one that poses no increased health risk for either the consumer or the target animal.

 Basionym: Pycreus vanderystii Cherm., Rev. Zool. Bot. Africaines 24: 296 (Chermezon 1933 publ. 1934) ≡ Cyperus fibrillosus var. vanderystii (Cherm.) Kük. (Kükenthal 1936: 348).
 Lectotype (designated here):— CONGO, Vanderyst 16469 (hololectotype BR!).
 Description: —Chermezon (1934: 296).
 Note: —Chermezon (1933 publ. 1934) already remarked that Pycreus vanderystii is closely related to P. scaettae when describing both taxa in the same publication. They have the same habit, spikelet and glume shapes, and their rachillas are straight. Pycreus vanderystii only differs in its overall larger dimensions of the plant and of the glumes, and its yellowish glume colour. Although most plants can easily be placed in one of both taxa based on the average size of the glumes, there is a slight overlap in the glume size range. Since it concerns sympatric taxa, recognising P. vanderystii at variety level seems most appropriate. As discussed under Cyperus scaettae, C. fibrillosus is clearly distinct because of its flexuous rachilla and different glumes. Therefore, P. vanderystii should not be included into the latter species as was done by Kükenthal (1936).

 Notes on synonymy of an African ‘ Pycreus ’ species
 Pycreus sanguineosquamatus has not yet been combined into Cyperus. However, in our opinion, this name represents a species that needs to be placed in synonymy of an older species, i.e. Cyperus fontinalis. Therefore, a new combination into Cyperus would be superfluous.

description: We study ground state and finite temperature properties of disordered heavy fermion metals by using a generalization of dynamical mean field theory which incorporates Anderson localization effects. The emergence of a non-Fermi liquid metallic behavior even at moderate disorder is shown to be a universal phenomenon resulting from local density of states fluctuations. This behavior is found to have a character of an electronic Griffiths phase, and can be thought of as a precursor of Anderson localization in a strongly correlated host. The temperature dependence of the conducting properties of the system reveal a non-trivial interplay between disorder and inelastic processes, which is reminiscent of the Mooij correlations observed in many disordered metals.

description: We present a detailed NQR, NMR and $μ$SR study of a magnetic phase obtained during a topotactic chemical reaction of YBa$_{2}$Cu$_{3}$O$_{6.5}$ high- temperature superconductor with low-pressure water vapor. Our studies give straightforward evidence that the ''empty'' Cu(1) chains play the role of an easy water insertion channel. It is shown that the NQR spectrum of the starting material transforms progressively under insertion of water, and completely disappears when one H$_{2}$O molecule is inserted per unit cell. Similarly, a Cu ZFNMR signal characteristic of this water inserted material appears and grows with increasing water content, which indicates that the products of the reaction are non-superconducting antiferromagnetic phases in which the bilayers are ordered. These antiferromagnetic phases are felt by proton NMR which reveals two sites with static internal fields of 150 and about 15 Gauss respectively. Two muon sites are also evidenced with similar local fields which vanish at $T\approx 400$ K. This indicates that the magnetic phases have similar Néel temperatures as the other bilayer undoped compounds. An analysis of the internal fields on different sites of the structure suggests that they can be all assigned to a single magnetic phase at large water content in which the Cu(1) electron spins order with those of the Cu(2). It appears that even samples packed in Stycast epoxy resin heated moderately at a temperature (200$^{0}$C) undergo a reaction with epoxy decomposition products which yield the formation of the same final compound. It is then quite clear that such effects should be considered quite seriously and avoided in experiments attempting to resolve tiny effects in such materials, as those performed in some recent neutron scattering experiments.

description: The detection of gravitational waves has ushered in a new era of observing the universe. Quantum resource advantages offer significant enhancements to the sensitivity of gravitational wave observatories. While squeezed states for ground-based gravitational wave detection have received marked attention, the generation of squeezed states suitable for mid-to-low-frequency detection has remained unexplored. To address the gap in squeezed state optical fields at ultra-low frequencies, we report on the first direct observation of a squeezed vacuum field until Fourier frequency of 4 millihertz with the quantum noise reduction of up to 8 dB, by the employment of a multiple noise suppression scheme. Our work provides quantum resources for future gravitational wave observatories, facilitating the development of quantum precision measurement.

description: The capability of cells to alter their phenotype in response to signals is crucial to the understanding of different morphogenetic pathways. We focus presently on the case of Epithelial-to-Mesenchynaml Transition (EMT) and its reverse Mesenchymal-to-Epithelial Transition (MET), which are considered as a plausible mechanism at the base of tumours onset and spread. We propose a simplified mathematical model, consisting of two coupled differential equations, aiming to describe the minimal dynamics of Epithelial and Mesenchymal cells. Differently from many previous models arising in various contexts, the basic assumption is the presence of a cooperative-like structure between the two families determined by the presence of a source term (possibly nonlinear) involving cells of the opposite compartment, in addition to an inherent apoptosis term. Finally, being the Mesenchymal phenotype characterised by high-level motility, the presence of motion is included into its dynamics by means of a diffusive-like term. In case the source term is truly nonlinear and, as a consequence, multiple equilibria may coexist, propagating fronts connecting such different states can be numerically observed. For different values of the parameters, specifically the relaxation times σ and t, the measure of invasiveness λ and μ , together with functions f and g, the model is capable to describe various directions of propagation, also suggesting a possible simple mechanism responsible for tumour reversion.

description: Fe(II)-porphyrins (FeP) play an important role in many reactions relevant to material science and biological processes, due to their closely lying spin states. However, this small energetic separation also makes it challenging to establish the correct spin state ordering. Although the prevalent opinion is that these systems posses the triplet ground state, the recent experiment on Fe(II)-phthalocyanine under conditions matching those of an isolated molecule points toward the quintet ground state. We present a thorough study of FeP model by means of the density functional theory and density matrix renormalization group based tailored coupled clusters, in which we address all previously discussed correlation effects. We examine the importance of geometrical parameters, the Fe-N distances in particular, and conclude that the system possesses the quintet ground state, which is in our calculations well-separated from the triplet state.
One-parameter orthogonality relations for basic hypergeometric series

description: The second order hypergeometric q-difference operator is studied for the value c=-q. For certain parameter regimes the corresponding recurrence relation can be related to a symmetric operator on the Hilbert space l^2(Z). The operator has deficiency indices (1,1) and we describe as explicitly as possible the spectral resolutions of the self-adjoint extensions. This gives rise to one-parameter orthogonality relations for sums of two 2\phi1-series. In particular, we find that the Ismail-Zhang q-analogue of the exponential function satisfies certain orthogonality relations analogous to the Fourier cosine transform.

Nonmonotonic Hall effect of Weyl semimetals under magnetic field

description: Hall effect of topological quantum materials often reveals essential new physics and possesses potential for application. Magnetic Weyl semimetal is one especially interesting example that hosts an interplay between the spontaneous time-reversal symmetry-breaking topology and the external magnetic field. However, it is less known beyond the anomalous Hall effect thereof, which is unable to account for plenty of magnetotransport measurements. We propose a new Hall effect characteristically nonmonotonic with respect to the external field, intrinsic to the three-dimensional Weyl topology and free from chemical potential fine-tuning. Two related mechanisms from the Landau level bending and chiral Landau level shifting are found, together with their relation to Shubnikov-de Hass effect. This field-dependent Hall response, universal to thin films and bulk samples, provides a concrete physical picture for existing measurements and is promising to guide future experiments.

description: Recent zoom-in cosmological simulations have shown that stellar feedback can flatten the inner density profile of the dark matter halo in low-mass galaxies. A correlation between the stellar/gas velocity dispersion ($σ_{star}$, $σ_{gas}$) and the specific star formation rate (sSFR) is predicted as an observational test of the role of stellar feedback in re-shaping the dark matter density profile. In this work we test the validity of this prediction by studying a sample of star-forming galaxies at $0.6

description: The study of domestic and international migration within and to the United States is deep and wide, but as yet no one has developed and tested models that focus on the use of knowledge economy, economic freedom, and personal freedom indexes. Using statistical regression models and following the lead of Cebula-Alexander, we build models for people Daniel Boorstin called “Go-Getters.” We model migration patterns across the 50 states for domestic and international movers in the 25-39-year age group for the years 2004-2008. We find dramatic differences in the determinants of migration for the two groups. All else equal, international movers are driven more by state knowledge economy developments and personal freedom. Domestic movers are not attracted by stronger knowledge economies but are driven by higher levels of state creativity and economic freedom.
