description: We study incompressible Navier--Stokes flows in~$\R^d$ with small and well localized data and external force~$f$. We establish pointwise estimates for large~$|x|$ of the form \hbox{$c_t|x|^{-d}\le |u(x,t)|\le c'_t|x|^{-d}$}, where $c_t>0$ whenever $\int_0^t\!\!\int f(x,s)\,dx\,ds\not=\vec 0$. This sharply contrasts with the case of the Navier--Stokes equations without force, studied in [Brandolese, Vigneron, J. Math. Pures Appl. 88, 64--86 (2007)], where the spatial asymptotic behavior was $|u(x,t)|\simeq C_t|x|^{-d-1}$. In particular, this shows that external forces with non-zero mean, no matter how small and well localized (say, compactly supported in space-time), increase the velocity of fluid particles at {\it all times~$t$} and at \emph{at all points~$x$} in the far-field. As an application of our analysis on the pointwise behavior, we deduce sharp upper and lower bounds of weighted $L^p$-norms for strong solutions, extending the results obtained in [Bae, Brandolese, Jin, Asymptotic behavior for the Navier--Stokes equations with nonzero external forces, Nonlinear analysis, doi:10.1016/j.na.2008.10.074] for weak solutions, by considering here a larger (and in fact, optimal) class of weight functions.

description: The aim of this study was to neurophysiologically demonstrate the activities of the premotor nuclei of sympathetic vasomotion, by capturing the diachronic changes in the action potentials which are generated in the pons and medulla oblongata. To do so, ten male Wistar rats weighing 300g were used as subjects. Microelectrodes were inserted in the muscular branch of the sciatic nerve and the ventral side of the pons and medulla oblongata, and the muscle sympathetic nerve activity (MSA) was induced. The regular spontaneous action potentials, which synchronize with muscle sympathetic nerve activity, were observed in the rostral ventrolateral medulla oblongata (RVLM), and the differences among the action potentials of individual cells of the RVLM region noted. Autonomic postganglionic nerves are controlled in turn by preganglionic nerves that originate from specific nuclei in the medulla. These nerves directly influence cardiovascular function by regulating the rate and force of contraction of the heart and the diameter of blood vessels. RVLM cells in fact exert a widespread control over the sympathetic outflow. We conclude from the experiment that premotor nuclei of sympathetic vasomotion exist in the RVLM.

description: Environmental or intrinsic stressors acting on growing animals and humans may be expressed as small, random deviations from symmetry in otherwise bilaterally symmetrical characters – a phenomenon known as fluctuating asymmetry (FA), the mechanism behind which is not yet clear. In this study, we investigated the effects of two known stressors (grid floor and single housing) on the development of FA in young male Lewis rats compared to housing under normal conditions (bedding) or an enriched environment. It was found that such environmental factors have an impact on FA in rats. Initially, FA was found to be high in all rats. In bedding and in enrichment groups, FA decreased throughout the study (P<0.05 in bedding group and P<0.001 in enrichment group from five to eleven weeks of age). FA in singly housed rats and in rats on a grid floor did not change significantly throughout the study. FA in these rats was considerably higher than in rats housed on bedding with or without environmental enrichment (P<0.001). Moreover, the influence of social status on FA was evaluated. Dominant rats housed in the enriched environment were found to have a higher FA of combined traits than subordinate rats at eight weeks of age (P<0.01), but except for this result, no relationship between FA and dominance was found. Singly housed rats showed significantly higher FA than dominant as well as subordinate rats (P<0.001). In conclusion, FA of selected traits may hold a potential for measuring stress influences in laboratory animals, which can be of some importance in welfare research.

description: The purpose of the study was to quantify behavioural changes of healthy Göttingen minipigs in response to experimentally altered dopamine neurotransmission. Since dopamine function is important in the pathogenesis of several human neuropsychiatric diseases, it is important for future evaluation of minipig models of diseases involving dopamine that the changes in behaviour in response to changed neurotransmitter function can be quantified. We recorded the behaviour of eight Göttingen minipigs in a ten-minute open field and a five-minute novelty test, and investigated the effects of d-amphetamine (0.7 mg/kg) and haloperidol (0.2 mg/kg) in this setting. D-amphetamine as well as haloperidol produced appreciable changes in motor behaviour and decreased explorative behaviour in line with the elsewhere reported effect of these drugs. It was possible to make a clear distinction between the behavioural profiles of these compounds. In conclusion, we have demonstrated the usefulness of a ten-minute open field and a five-minute novelty test for quantifying behavioural changes of Göttingen minipigs in response to experimentally altered dopamine neurotransmission. This provides the basis for using these behavioural tests in future evaluations of minipig models of diseases characterised by dopaminergic disturbances.

description: Problems in econometrics, insurance, reliability engineering, and statistics quite often rely on the assumption that certain functions are non-decreasing. To satisfy this requirement, researchers frequently model the underlying phenomena using parametric and semi-parametric families of functions, thus effectively specifying the required shapes of the functions. To tackle these problems in a non-parametric way, in this paper we suggest indices for measuring the lack of monotonicity in functions. We investigate properties of the indices and also offer a convenient computational technique for practical use.

description: Although the favored glide planes in hexagonal close-packed Zr are prismatic, screw dislocations can escape their habit plane to glide in either pyramidal or basal planes. Using abinitio calculations within the nudged elastic band method, we show that, surprisingly, both events share the same thermally activated process with an unusual conservative motion of the prismatic stacking fault perpendicularly to itself. Halfway through the migration, the screw dislocation adopts a nonplanar metastable configuration with stacking faults in adjacent prismatic planes joined by a two-layer pyramidal twin.

description: The collision theory for power-law distributions and a generalized collision theory rate coefficient is studied when the reactions take place in nonequilibrium systems with power-law distributions. We obtain the power-law rate coefficient and by numerical analyses we show a very strong dependence of the rate coefficient on the power-law parameter. We find that the power-law collision theory can successfully overcome the two difficulties of Lindemann-Christiansen mechanism. We take three reactions as examples to calculate the pre-exponential factor and yield the values that can be exactly in agreement with those measured in the experimental studies.

description: The influence of subcutaneous injections of dextran sulphate (DS) and fibrin (F), as well as of an intraperitoneal injection of ubiquitin (Ub), was investigated on 48 male C57BL/6 mice subjected to conventional casein (C) induced amyloidosis. Histopathological examination of spleen and kidney tissue 3 and 5 weeks after termination of the amyloidogenic stimulus showed that the amount of amyloid deposited (rated trace, minimal, moderate or heavy) increased progressively with the duration of the amyloidogenic stimulus. After 3 weeks of stimulation, 16.7% of mice injected with C had some perifollicular amyloid deposits in the spleen while all had traces of amyloid in the kidney. Some amyloid was detected in the spleen of 33.3% of the mice treated with C+DS and C+Ub and 83.3% treated with C+F. Half the latter group also showed traces and half minimal amyloid deposits in their kidneys. In the other test groups, the incidence of kidney amyloidosis was less. The most extensive tissue deposits were seen at 5 weeks postinjection (p.i.) with most in the C+F-treated animals, all showing significantly more than the control C-treated group. Thus half the C+F-treated animals had moderate and half heavy deposits throughout their spleens. Glomerulonephritis, kidney tubular edema and some amyloid deposits were present in all of the animals. C+Ub resulted in a similar incidence of amyloid accumulation in the spleen but in the kidneys 66.7% of animals had only traces of amyloid and 33.3%, minimal amyloid deposits. Amyloid was deposited in the mouse kidneys predominantly in the arterial walls but also occurred in the basement membrane and interstitial tissues. A post-mortem examination of the internal organs revealed splenomegaly in all the test groups and increased liver weight in the C-, C+F-, and C+Ub-treated groups. The leukocyte count and ESR (erythrocyte sedimentation rate) were also higher in all the experimental groups. Thus, the results indicated that F and Ub play a role in the amyloid deposition process in the experimentally induced disorder in C57BL/6 mice and could enhance this pathological process.

description: Rats are being used in models of experimental periodontitis because the periodontal anatomy in the molar region bears much resemblance to that of man. Furthermore, rats are available with different genomes and microbial status. The main purpose of the study was to compare two different methods of inducing experimental periodontitis in rats, by ligature or LPS injection. Rats were bred and housed on wire-mesh floor with no bedding material and fed a special diet to avoid periodontal destruction caused by impaction of bedding and dietary fibers interdentally. Because no bedding was used it was suggested that in future studies PVC tubes (diameter: 7 cm, length: 12-15 cm) be placed in the cages to improve the environment for the rats. The possible effect of doing so was therefore also examined in this study. Periodontitis was established either with peridental silk ligatures for 1 or 4 weeks or with gingival injections of lipopolysaccharide (LPS) every other day for a 6-day-period to provoke inflammation. For each experimental group a corresponding control group was established. In all groups the number of rats was 14. In addition 10 rats receiving no treatment were placed in cages with PVC-tubes. Alveolar bone loss was measured by means of morphometrical and radiographical methodologies. A previously described method for breeding and housing periodontitis-free rats was reproduced. The access to PVC-tubes did not result in differences in alveolar bone destruction when compared to the 4-week control group and therefore, PVC-tubes may be used as an environmental improvement for the rats in future studies. Compared to the control groups significantly more alveolar bone loss was established in the ligated rats both after 1 and 4 weeks, with the 4-weeks-ligature group having significantly more alveolar bone destruction than the 1-week-ligature group. No effect of LPS injections could be demonstrated and therefore, the study did not confirm earlier findings of significant effect of LPS injection on alveolar bone destruction as compared to saline injection.

description: Electromagnetically-induced-transparency (EIT) and Autler-Townes splitting (ATS) are two prominent examples of coherent interactions between optical fields and multilevel atoms. They have been observed in various physical systems involving atoms, molecules, meta-structures and plasmons. In recent years, there has been an increasing interest in the implementations of all-optical analogues of EIT and ATS via the interacting resonant modes of one or more optical microcavities. Despite the differences in their underlying physics, both EIT and ATS are quantified by the appearance of a transparency window in the absorption or transmission spectrum, which often leads to a confusion about its origin. While in EIT the transparency window is a result of Fano interference among different transition pathways, in ATS it is the result of strong field-driven interactions leading to the splitting of energy levels. Being able to tell objectively whether a transparency window observed in the spectrum is due to EIT or ATS is crucial for clarifying the physics involved and for practical applications. Here we report a systematic study of the pathways leading to EIT, Fano, and ATS, in systems of two coupled whispering-gallery-mode (WGM) microtoroidal resonators. Moreover, we report for the first time the application of the Akaike Information Criterion discerning between all-optical analogues of EIT and ATS, and clarifying the transition between them.

description: Cardiovascular disorders like hypertension, cerebral stroke, heart failure and thromboembolism account for a high degree of morbidity and mortality all over the World. As the regulation of the cardiovascular system is complex, the study of cardiovascular disorders has been limited to whole-organism models. The last decade has witnessed an upsurge in transgenic and gene knockout technologies, which have played a major role in the discovery of a particular gene, or its product, implicated in various cardiovascular disorders. Knockout and transgenic animals are likely to become important tools in drug development to determine the physiological sites of action for newly developed pharmacological agents. The present review will briefly discuss the methods and types of genetically engineered rodents (transgenic and gene knockout models) with alterations in second messenger systems involved in cardiovascular disorders.

description: Over recent years alternative, non-animal methods have been developed for use in microsurgical training courses, for the training of suture techniques, dexterity and hand-eye coordination. Nevertheless, it is still hard to imagine that alternative methods will be able to replace in vivo teaching completely, because properties of biological tissue are different from those of latex or other artificial materials. Also the dynamics of biological processes, such as a pulsating bloodstream, are difficult to simulate in alternative models. However, the number of animals used in microsurgical training courses can be limited by combining non-animal methods with in vivo training. Moreover, individual techniques can be improved greatly by using non-animal methods. In a five-day introductory course in microsurgical and experimental techniques at the Biomedical Laboratory, University of Southern Denmark, we have limited the average number of animals to one rat per day per participant, by using alternative non-animal methods extensively on the first course day. Nearly all participants were able to produce a successful end-to-end anastomosis of the femoral artery during the second or third day of the course. The alternative methods used included a training device for microsurgical anastomosis and the MD PVC-Rat, an artificial rat with life-size latex abdominal vessels.

description: Dexter-type long-term bone marrow culture is a myelopoietic culture system that allows maintenance of mouse and human hematopoiesis in vitro over a period of several months. In mouse unperturbed long-term bone marrow culture, erythropoiesis activity is limited to the production of immature erythroid progenitors (BFU-E) from primitive hematopoietic stem cells. In this study the effects of mouse lung conditioned medium (MLCM) as a source of myeloid growth factors, on long-term mouse bone marrow cultures was studied. Numbers of cells in adherent and non-adherent layers of cultures were counted weekly and the morphological appearances of mature cells that were produced in non-adherent layers were analyzed. In the presence of MLCM, mature nonnucleated and hemoglobinized red blood cells were produced in the nonadherent layers of the cultures.

description: We examine whether the principle of detailed balance holds for the power-law distributions generated from the general Langevin equation under the generalized fluctuation-dissipation relation (FDR). With the detailed balance and the generalized FDR, we derive analytically the stationary power-law distribution from the Ito's, Stratonovich's and Zwanzig's Fokker-Planck equations, and conclude that the power-law distributions can either be a stationary nonequilibrium distribution or an equilibrium distribution, which depend on information about the form of the diffusion coefficient function, and the existence and uniqueness of an equilibrium state.

description: We test a new "hybrid" scheme for simulating dynamical fluid flows in which cylindrical components of the momentum are advected across a rotating Cartesian coordinate mesh. This hybrid scheme allows us to conserve angular momentum to machine precision while capitalizing on the advantages offered by a Cartesian mesh, such as a straightforward implementation of mesh refinement. Our test focuses on measuring the real and imaginary parts of the eigenfrequency of unstable axisymmetric modes that naturally arise in massless polytropic tori having a range of different aspect ratios, and quantifying the uncertainty in these measurements. Our measured eigenfrequencies show good agreement with the results obtained from the linear stability analysis of Kojima (1986) and from nonlinear hydrodynamic simulations performed on a cylindrical coordinate mesh by Woodward et al. (1994). When compared against results conducted with a traditional Cartesian advection scheme, the hybrid scheme achieves qualitative convergence at the same or, in some cases, much lower grid resolutions and conserves angular momentum to a much higher degree of precision. As a result, this hybrid scheme is much better suited for simulating astrophysical fluid flows, such as accretion disks and mass-transferring binary systems.

description: To investigate whether the dense Kondo compound CeB6 might evolve into a topological insulator under sufficient pressure, four-point electrical resistivity measurements have been carried out over the temperature range 1.3 K to 295 K in a diamond anvil cell to 122 GPa. The temperature of the resistivity maximum initially increases slowly with pressure but disappears between 12 and 20 GPa. The marked changes observed under pressure suggest that a valence and/or structural transition may have occurred. Synchrotron x-ray diffraction measurements, however, fail to detect any change in crystal structure to 85 GPa. Although a transition into an insulating phase is not observed, this dense Kondo system is completely suppressed at 43 GPa, leaving behind what appears to be a conventional Fermi liquid metal.

description: Many factors may interact with normal differentiation and growth of tissues and cells. Stress might be experienced during pregnancy and it has been shown that stress may cause low birth weight. The effect of prenatal manipulations on the HPA axis has been focused on physiological and biochemical alteration of the adrenal gland. A stereological examination of the influences of prenatal stress on the structure of the developing adrenal gland of one day and 21 day-old rats has now been performed. In this study experiments were conducted to test the hypothesis that exposure to restraint stress during pregnancy in rat results in structural changes in the developing adrenal gland of their pups. Female rats were exposed to restraint stress from the first day of pregnancy throughout gestation. Male offspring of stressed rats (PS= experimental) and of unstressed mothers (C= control) who were one day and 21 days of age were selected. Their body weight (BW), crown-rump length (CRL), biparietal diameter (BPD), volume of the gland and the cortical layers and medulla were estimated using stereological methods. The results showed that the prenatal stress led to a decrease in BW, but CRL and BPD remained unchanged. Also, a significant increase in volume of the adrenal gland and cortical layers in one day and 21 day-old offspring were observed. The volume of the medulla of the adrenal gland of neonate rats remained unchanged but the volume of the medulla in 21 day-old rats was decreased. Therefore, it can be concluded that prenatal stress alters the structure of the developing adrenal gland.

description: We perform a comprehensive study of the $Δ(96)$ family symmetry combined with the generalised CP symmetry $H_{\rm{CP}}$. We investigate the lepton mixing parameters which can be obtained from the original symmetry $Δ(96)\rtimes H_{\rm{CP}}$ breaking to different remnant symmetries in the neutrino and charged lepton sectors, namely $G_ν$ and $G_l$ subgroups in the neutrino and the charged lepton sector respectively, and the remnant CP symmetries from the breaking of $H_{\rm{CP}}$ are $H^ν_{\rm{CP}}$ and $H^{l}_{\rm{CP}}$, respectively, where all cases correspond to a preserved symmetry smaller than the full Klein symmetry, as in the semi-direct approach, leading to predictions which depend on a single undetermined real parameter, which may be fitted to the reactor angle for example. We discuss 26 possible cases, including a global $χ^2$ determination of the best fit parameters and the correlations between mixing parameters, in each case.

description: Wavelets and their associated transforms are highly efficient when approximating and analyzing one-dimensional signals. However, multivariate signals such as images or videos typically exhibit curvilinear singularities, which wavelets are provably deficient of sparsely approximating and also of analyzing in the sense of, for instance, detecting their direction. Shearlets are a directional representation system extending the wavelet framework, which overcomes those deficiencies. Similar to wavelets, shearlets allow a faithful implementation and fast associated transforms. In this paper, we will introduce a comprehensive carefully documented software package coined ShearLab 3D (www.ShearLab.org) and discuss its algorithmic details. This package provides MATLAB code for a novel faithful algorithmic realization of the 2D and 3D shearlet transform (and their inverses) associated with compactly supported universal shearlet systems incorporating the option of using CUDA. We will present extensive numerical experiments in 2D and 3D concerning denoising, inpainting, and feature extraction, comparing the performance of ShearLab 3D with similar transform-based algorithms such as curvelets, contourlets, or surfacelets.

description: The SDSS-III APOGEE collaboration has identified a single useable line in the H-band spectra of APOGEE target stars arising from a singly ionized species. This line of Ti II ($λ_{air}$ = 15873.84 Å) is therefore of great importance for use in stellar surface gravity, or log(g), determinations via the Saha equation. While a theoretical estimate of the line strength exists, to date no laboratory measurement of the line strength has been reported. Herein we report an absolute laboratory transition probability measurement for this important Ti II line. A relative line strength measurement is made of the Ti II H-band line of interest and a reference line with a previously reported absolute transition probability. This ratio is measured using multiple spectra of a high-current water-cooled HC lamp recorded with a calibrated FT-IR spectrometer.

description: A wide range of interacting systems can be described by complex networks. A common feature of such networks is that they consist of several communities or modules, the degree of which may quantified as the \emph{modularity}. However, even a random uncorrelated network, which has no obvious modular structure, has a finite modularity due to the quenched disorder. For this reason, the modularity of a given network is meaningful only when it is compared with that of a randomized network with the same degree distribution. In this context, it is important to calculate the modularity of a random uncorrelated network with an arbitrary degree distribution. The modularity of a random network has been calculated [Phys. Rev. E \textbf{76}, 015102 (2007)]; however, this was limited to the case whereby the network was assumed to have only two communities, and it is evident that the modularity should be calculated in general with $q(\geq 2)$ communities. Here, we calculate the modularity for $q$ communities by evaluating the ground state energy of the $q$-state Potts Hamiltonian, based on replica symmetric solutions assuming that the mean degree is large. We found that the modularity is proportional to $\langle \sqrt{k} \rangle / \langle k \rangle$ regardless of $q$ and that only the coefficient depends on $q$. In particular, when the degree distribution follows a power law, the modularity is proportional to $\langle k \rangle^{-1/2}$. Our analytical results are confirmed by comparison with numerical simulations. Therefore, our results can be used as reference values for real-world networks.

description: We investigate the influence of impacts of large planetesimals and small planetary embryos on the early Martian surface on the hydrodynamic escape of an early steam atmosphere that is exposed to the high soft X-ray and EUV flux of the young Sun. Impact statistics in terms of number, masses, velocities, and angles of asteroid impacts onto the early Mars are determined via n-body integrations. Based on these statistics, smoothed particle hydrodynamics (SPH) simulations result in estimates of energy transfer into the planetary surface material and according surface heating. For the estimation of the atmospheric escape rates we applied a soft X-ray and EUV absorption model and a 1-D upper atmosphere hydrodynamic model to a magma ocean-related catastrophically outgassed steam atmosphere with surface pressure values of 52 bar H2O and 11 bar CO2. The estimated impact rates and energy deposition onto an early Martian surface can account for substantial heating. The energy influx and conversion rate into internal energy is most likely sufficient to keep a shallow magma ocean liquid for an extended period of time. Higher surface temperatures keep the outgassed steam atmosphere longer in vapor form and therefore enhance its escape to space within about 0.6 Myr after its formation.

Heavy-ion fusion cross sections of weakly bound $^{9}$Be on $^{27}$Al, $^{64}$Zn and tightly bound $^{16}$O on $^{64}$Zn target using Coulomb and proximity potential

description: The total fusion cross sections for the fusion of weakly bound $^{9}$Be on $^{27}$Al and $^{64}$Zn targets at near and above the barrier have been calculated using one dimensional barrier penetration model, taking scattering potential as the sum of Coulomb and proximity potential and the calculated values are compared with experimental data. For the purpose of comparison of the fusion of weakly bound projectiles and strongly bound projectiles, the total fusion cross sections for the reaction of tightly bound nucleus $^{16}$O on $^{64}$Zn have also been computed using a similar procedure. The calculated values of total fusion cross sections in all cases are compared with coupled channel calculations using the code CCFULL. The computed cross sections using Coulomb and proximity potential explain the fusion reactions well in both cases of weakly bound and strongly bound projectiles. Reduced reaction cross sections for the systems $^{9}$Be + $^{27}$Al, $^{9}$Be+ $^{64}$Zn and $^{16}$O + $^{64}$Zn have also been described.

description: We consider a wiretap channel and use previously transmitted messages to generate a secret key which increases the secrecy capacity. This can be bootstrapped to increase the secrecy capacity to the Shannon capacity without using any feedback or extra channel while retaining the strong secrecy of the wiretap channel.

Discovery of Enhanced Radiative Recombination Continua of He-like Iron and Calcium from IC 443 and Its Implications

description: We present deep observations of the Galactic supernova remnant IC 443 with the {\it Suzaku X-ray satellite}. We find prominent K-shell lines from iron and nickel, together with a triangle residual at 8--10~keV, which corresponds to the energy of the radiative recombination continuum (RRC) of He-like iron. In addition, the wavy residuals have been seen at $\sim$5.1 and $\sim$5.5~keV. We confirm that the residuals show the first enhanced RRCs of He- and H-like calcium found in supernova remnants. These facts provide robust evidence for the recombining plasma. We reproduce the plasma in the 3.7--10~keV band using a recombining plasma model at the electron temperature 0.65~keV. The recombination parameter $n_{\rm e}t$ ($n_{\rm e}$ is electron density and $t$ is elapsed time after formation of a recombining plasma) and abundances of iron and nickel are strongly correlated, and hence the errors are large. On the other hand, the ratio of nickel to iron relative to the solar abundances is well constrained to 11$^{+4}_{-3}$ (1$σ$). A possibility is that the large abundance ratio is a result of an asymmetric explosion of the progenitor star.

description: The African soft-furred rat (Mastomys natalensis) has been shown to be a possible model for propagation of Trypanosoma brucei gambiense. This study aimed at determining the baseline biological reference values and reproductive data of a laboratory bred Mastomys colony, which was established at TRC. In addition, the effect of cyclophosphamide (an immunosuppressant) treatment (s) on the haematological profile was investigated. The mean gestation period was 23 days and the mean litter size was eight. At birth, the pups weighed 2.4±0.23 g and the weights increased to 78.0±10.6 g in males and 53.9±4.5 g in females by 90 days. The mean haematological values were significantly (p<0.05) higher in adults than juveniles. However, there was no statistical difference of haematological values between the sexes. Cyclophosphamide treatment caused a macrocytic hypochromic anaemia, which was noted 24 hours after treatment and was more severe in animals treated more than once. Thus, in studies involving a disease that causes anaemia, repeated cyclophosphamide treatment should be limited. Our study is a contribution to the clinical and biological characterization of the disease pattern in this preferred rodent model of T. b. gambiense.

description: In this paper we analyze and discuss the historical and philosophical development of the notion of logical possibility focusing on its specific meaning in classical and quantum mechanics. Taking into account the logical structure of quantum theory we continue our discussion regarding the Aristotelian Square of Opposition in orthomodular structures enriched with a monadic quantifier. Finally, we provide an interpretation of the Orthomodular Square of Opposition exposing the fact that classical possibility and quantum possibility behave formally in radically different manners.

description: We prove that the universal enveloping algebra of a Poisson-Ore extension is a length two iterated Ore extension of the original universal enveloping algebra. As consequences, we observe certain ring-theoretic invariants of the universal enveloping algebras that are preserved under iterated Poisson-Ore extensions. We apply our results to iterated quadratic Poisson algebras arising from semiclassical limits of quantized coordinate rings and a family of graded Poisson algebras of Poisson structures of rank at most two.
