description: The insulating magnetic material Fe3PO4O3 features a non-centrosymmetric lattice composed of Fe^{3+} triangular units. Frustration, due to competing near neighbor ($J_1$) and next nearest neighbor ($J_2$) antiferromagnetic interactions, was recently suggested to be the origin of an antiferromagnetic helical ground state with unusual needle-like nanoscale magnetic domains in Fe3PO4O3. Magnetic dilution is shown here to tune the ratio of these magnetic interactions, thus providing deeper insight into this unconventional antiferromagnet. Dilution of the Fe^{3+} lattice in Fe3PO4O3 was accomplished by substituting non-magnetic Ga^{3+} to form the solid solution series Fe_{3-x}Ga_xPO4O3 with $x = 0.012, 0.06, 0.25, 0.5, 1.0, 1.5$. Magnetic susceptibility and neutron powder diffraction data from this series are presented. A continuous decrease of the both the helical pitch length and the domain size is observed with increasing dilution up to at least $x = 0.25$, while for $x \ge 0.5$, the compounds lack long range magnetic order entirely. The decrease in the helical pitch length with increasing $x$ can be qualitatively understood by reduction of the ratio of $J_2/J_1$ in the Heisenberg model, consistent with mean field considerations. Intriguingly, the magnetic correlation length in the $ab$ plane remains nearly equal to the pitch length for each value of $x \le 0.25$, showing that the two quantities are intrinsically connected in this unusual antiferromagnet.

description: A sample of 37 nearby galaxies displaying composite LINER/HII and pure HII spectra was observed with the VLA in an investigation of the nature of their weak radio emission. The resulting radio contour maps overlaid on optical galaxy images are presented here, together with an extensive literature list and discussion of the individual galaxies. Radio morphological data permit assessment of the ``classical AGN'' contribution to the global activity observed in these ``transition'' LINER galaxies. One in five of the latter objects display clear AGN characteristics: these occur exclusively in bulge-dominated hosts.

description: Schwarzfeministische Perspektiven auf KI bieten eine Analyse und Kritik von Techniken wie Gesichtserkennung und Überwachung, die Mainstream-Debatten um AI Ethics ergänzen und herausfordern. Der Beitrag zieht drei Analyserahmen des US-amerikanischen Schwarzen Feminismus heran (Unterdrückung, Hypervisibility/Invisibility, Widerstand) und diskutiert in Anwendung auf den Fall von Gesichtserkennung und Überwachung den Mehrwert der mithilfe dieser Analyserahmen gewonnenen Erkenntnisse. Dabei zeigt sich, dass KI-gestützte Gesichtserkennung und Überwachung im historischen Kontext eingebettet und im Hinblick auf ihre zugrundeliegenden Werte betrachtet werden müssen. Der Beitrag diskutiert Schwarzfeministische Lösungsansätze für ethisch bedenkliche Technik von reformorientierten bis hin zu abolitionistischen Ansätzen, welche die Abschaffung unterdrückerischer Technik fordern.

description: NGC 6229 is a relatively massive outer halo globular cluster that is primarily known for exhibiting a peculiar bimodal horizontal branch morphology. Given the paucity of spectroscopic data on this cluster, we present a detailed chemical composition analysis of 11 red giant branch members based on high resolution (R ~ 38,000), high S/N (> 100) spectra obtained with the MMT-Hectochelle instrument. We find the cluster to have a mean heliocentric radial velocity of -138.1$_{-1.0}^{+1.0}$ km s$^{\rm -1}$, a small dispersion of 3.8$_{-0.7}^{+1.0}$ km s$^{\rm -1}$, and a relatively low (M/L$_{\rm V}$)$_{\rm \odot}$ = 0.82$_{-0.28}^{+0.49}$. The cluster is moderately metal-poor with = -1.13 dex and a modest dispersion of 0.06 dex. However, 18% (2/11) of the stars in our sample have strongly enhanced [La,Nd/Fe] ratios that are correlated with a small (~0.05 dex) increase in [Fe/H]. NGC 6229 shares several chemical signatures with M 75, NGC 1851, and the intermediate metallicity populations of omega Cen, which lead us to conclude that NGC 6229 is a lower mass iron-complex cluster. The light elements exhibit the classical (anti-)correlations that extend up to Si, but the cluster possesses a large gap in the O-Na plane that separates first and second generation stars. NGC 6229 also has unusually low [Na,Al/Fe] abundances that are consistent with an accretion origin. A comparison with M 54 and other Sagittarius clusters suggests that NGC 6229 could also be the remnant core of a former dwarf spheroidal galaxy.

A Comment on the Zero Temperature Chiral Phase Transition in $SU(N)$ Gauge Theories

description: Recently Appelquist, Terning, and Wijewardhana investigated the zero temperature chiral phase transition in SU(N) gauge theory as the number of fermions N_f is varied. They argued that there is a critical number of fermions N^c_f, above which there is no chiral symmetry breaking and below which chiral symmetry breaking and confinement set in. They further argued that that the transition is not second order even though the order parameter for chiral symmetry breaking vanishes continuously as N_f approaches N^c_f on the broken side. In this note I propose a simple physical picture for the spectrum of states as N_f approaches N^c_f from below (i.e. on the broken side) and argue that this picture predicts very different and non-universal behavior than is the case in an ordinary second order phase transition. In this way the transition can be continuous without behaving conventionally. I further argue that this feature results from the (presumed) existence of an infrared Banks-Zaks fixed point of the gauge coupling in the neighborhood of the chiral transition and therefore depends on the long-distance nature of the non-abelian gauge force.

description: We apply the reconstruction technique of Nusser & Dekel (1992) to the recently available Point Source Catalogue Redshift Survey (PSCz) in order to subtract the phase correlations that are expected to develop in the mild non-linear regime of gravitational evolution. We study the evolution of isodensity contours defined using an adaptive smoothing algorithm in order to minimize the problems derived from the non-comutivity of operators. We study the genus curves of the fields thus obtained and concentrate on the evolution of the amplitude drops, a meta-statistic able to quantify the level of phase-correlation present in the field. In order to test the method and to quantify the level of statistical uncertainty, we apply the method to a set of mock PSCz catalogues derived from the N-body simulations of two 'standard' CDM models, kindly granted to us by the Virgo consortium. We find the method to be reliable in recovering the right amplitude drops. When applied to PSCz, the level of phase correlations observed is very low on all scales ranging from 5h-1Mpc to 60 h-1Mpc, providing support to the theory that structure originated from gaussian initial conditions.

description: Several perspectives that can be opened by studying the electroexcitation of the delta via parity-violating electron scattering from nuclei are examined, working within the context of the relativistic Fermi gas model. A strong enhancement of the left-right asymmetry in the delta sector compared with that in the quasi-elastic regime is found and the potential to find clear signatures for the axial-vector contributions of the nucleon-to-delta transition to the asymmetry identified at specific low momentum transfer kinematics. Possibilities of probing the deformation of the delta are also explored, and using both the proton and nuclei as targets, the abilitiy to study the asymmetry on neutrons is studied.

description: The process e+e- --> W+W- provides a valuable laboratory to test the Standard Model (SM) and to search for new physics. The most general helicity amplitudes for this process require the introduction of nine form-factors which we calculate in the context of SU(2) X U(1) gauge-invariant extensions of the SM. The contributions of new physics are parametrized via an effective Lagrangian constructed from the light fields. Because the mechanism of electroweak symmetry-breaking remains an open problem we consider both the effective Lagrangian with a linearly realized Higgs sector, i.e. with a light physical Higgs boson, and the effective Lagrangian which utilizes a nonlinear realization of the Higgs mechanism. The use of an effective Lagrangian allows one to calculate consistently nonstandard contributions to e+e- --> W+W- amplitudes as well as the nonstandard contributions to other processes. We study the interplay of the low-energy and Z-pole measurements with measurements via the processes e+e- --> fermion pairs and e+e- --> W+W- at LEP II or a future linear e+e- collider. Concrete relationships between operators of the linear and nonlinear realizations are presented where possible.

description: Intersectionality is often understood to exist primarily as a corrective to other emancipatory theories rather than as a theory in its own right. Social reproduction theory (SRT), a strain of Marxist feminism exemplified in this article by contributors to the volume Social Reproduction Theory – Remapping Class, Recentering Oppression published in 2017, is characterized by a self-understanding that involves incorporating intersectional insights as a reaction to Black feminist interventions. In this narrative, intersectionality itself becomes obsolete, serving first and foremost as a step on SRT’s dialectical journey to becoming a better theory. Allegedly undertheorized intersectional frameworks constitute an ever-present foil for SRT’s self-image as an emancipatory theory of the capitalist social whole. This narrative is problematized on multiple levels in this article. SRT and its depiction of intersectionality are summarized in the first part of the paper. The second part demonstrates, on the one hand, that a historicization of intersectionality as ‘intervening’ into Marxist feminist theories, adding an intersectional perspective to feminist analysis of capitalism, ignores the formative role of analyses of Black women’s position as working subjects within overarching capitalist structures in intersectional thought. On the other hand, SRT's narrative occludes practical and theoretical implications of a framework that explicitly theorizes resistance from the margins. Building on this critique of SRT’s understanding of intersectionality, the third part develops an intersectional notion of solidarity, thus showing that the ostensibly seamless integration of intersectional insights into SRT obfuscates a potentially fruitful tension between the two frameworks pertaining to their respective understandings of solidarity and social transformation.

description: The octahedron tilt transitions of ABX_3 perovskite-structure materials lead to an anti-polar (or antiferroelectric) arrangement of dipoles, with the low temperature structure having six sublattices polarized along various crystallographic directions. It is shown that an important mechanism driving the transition is long range dipole-dipole forces acting on both displacive and induced parts of the anion dipole. This acts in concert with short range repulsion, allowing a gain of electrostatic (Madelung) energy, both dipole-dipole and charge-charge, because the unit cell shrinks when the hard ionic spheres of the rigid octahedron tilt out of linear alignment.

description: Moving beyond the legal and historical hegemonic definitions of the quilombo, this paper investigates continuities in gendered racial violence in Brazil by evoking the political and poetic of the quilombo. Inspired by the works of the historian and poet Beatriz Nascimento, the multifaceted notion of quilombo is conceptualized as an ongoing praxis of fugitivity and coalition that draws on the interconnectedness of anti-colonial, feminist, and anti-racist struggles. In exploring geopolitical breaks and epistemological ruptures, this paper fosters a necessary conversation between theory and practice by engaging with the living archives of three Afro-Brazilian writers and activists: (i) Beatriz Nascimento’s fundamental contributions on the political, material and symbolic dimensions of quilombo; (ii) the legacy and vision of Marielle Franco focusing on the necessity to ocupar the institutional politics like a growing seed; (iii) the work of Erica Malunguinho and Mandata Quilombo through the praxis of aquilombar the constitutional democracy, based on the alternation in representative power and repossession.

description: We investigate the reactions $πN \to a_0 N$ and $p p \to d a_0^+$ near threshold and at medium energies. An effective Lagragian approach and the Regge pole model are applied to analyze different contributions to the cross section of the reaction $πN \to a_0 N$. These results are used to calculate the differential and total cross sections of the reaction $p p \to d a_0^+$ within the framework of the two-step model in which two nucleons produce an $a_0$-meson via $π$ -meson exchange and fuse to a deuteron. The necessity of new measurements on $a_0$ production and branching fractions (of its decay to the $K\bar K$ and $πη$ channels) is emphasized for clarifying the $a_0$ structure. Detailed predictions for the reaction $pp \to d a_0^+$ are presented for the energy regime of the proton synchrotron COSY-Jülich.

CP Asymmetries in B Decays with New Physics in Decay Amplitudes

Year: 1996
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We make a systematic analysis of the effects of new physics in the B decay amplitudes on the CP asymmetries in neutral B decays. Although these are expected to be smaller than new physics effects on the mixing amplitude, they are easier to probe in some cases. The effects of new contributions to the mixing amplitude are felt universally across all decay modes, whereas the effects of new decay amplitudes could vary from mode to mode. In particular the prediction that the CP asymmetries in the B_d decay modes with $b\to c\bar c s, b \to c\bar c d, b\to c \bar u d$ and $ b\to s \bar s s$ should all measure the same quantity ($sin2β$ in the Standard Model) could be violated. Since the above Standard Model prediction is very precise, new decay amplitudes which are a few percent of the Standard Model amplitudes can be probed. Three examples of models where measurable effects are allowed are given: effective supersymmetry, models with enhanced chromomagnetic dipole operators, and supersymmetry without R parity.

description: We present the analysis of an extensive set of new and literature high quality data concerning Fe, C, N, O, Na, and Mg, exploiting the Teff scale determined in Gratton et al. (1996), and the non-LTE abundance corrections computed in Gratton et al. (1999). Results obtained with various abundance indices are discussed and compared. Our non-LTE analysis yields the same O abundances from both permitted and forbidden lines for stars with Teff>4600 K, in agreement with King (1993), but not with other studies using a lower Teff-scale for subdwarfs. However we obtain slightly smaller O abundances for the most luminous metal poor field stars than for fainter stars of similar metallicities, an effect attributed to inadequacies of the adopted model atmospheres (Kurucz 1992, with overshooting) for cool stars. We find a nearly constant O overundance in metal poor stars ([Fe/H]

description: We introduce an approach for calculating non-universal properties of rough surfaces. The technique uses concepts of distinct surface-configuration classes, defined by the surface growth rule. The key idea is a mapping between discrete events that take place on the interface and its elementary local-site configurations. We construct theoretical probability distributions of deposition events at saturation for surfaces generated by selected growth rules. These distributions are then used to compute measurable physical quantities. Despite the neglect of temporal correlations, our approximate analytical results are in very good agreement with numerical simulations. This discrete-event analytic technique can be particularly useful when applied to quantification problems, which are known to not be suited to continuum methods.

description: Han Y, Smithheart JW, Smyth RL, Aziz TN, Obenour CR. 2019. Assessing vertical diffusion and cyanobacteria bloom potential in a shallow eutrophic reservoir. Lake Reserv Manage. XX:XXX–XXX. Harmful blooms of cyanobacteria are an increasing threat to many lakes and reservoirs. While vertical mixing has been shown to be an important control on cyanobacteria dominance in some lakes, the relevance of mixing in relatively shallow turbid systems remains unclear. To explore mixing and its impact on cyanobacteria bloom potential, we leveraged data from a multiyear field campaign of a central North Carolina reservoir where artificial circulators were installed to (1) implement a parsimonious one-dimensional (1D) turbulent diffusion model with an artificial circulation term, (2) introduce a novel multi-objective calibration approach considering both water column temperature and stability, and (3) explore how mixing affects cyanobacteria bloom potential through changes in cyanobacteria light exposure relative to other algal taxa. Our multi-objective calibration approach is shown to realistically simulate both water temperature (R2 = 0.99) and water column stability (R2 = 0.62) throughout the year. Analysis of artificial mixing demonstrates the relative insignificance of the circulator deployment in our study area and suggests that at least eight times the implemented circulation rate would be required to substantially reduce the ability of buoyant cyanobacteria to outcompete other algal taxa for light. Overall, this study demonstrates an efficient and systematic approach for characterizing vertical mixing in lakes and reservoirs, which can be used to assess the viability of artificial circulation prior to deployment.

description: This volume contains the proceedings of the Combined 24th International Workshop on Expressiveness in Concurrency and the 14th Workshop on Structural Operational Semantics (EXPRESS/SOS 2017) which was held on 04 September 2017 in Berlin, Germany, as an affiliated workshop of CONCUR 2017, the 28th International Conference on Concurrency Theory. The EXPRESS workshops aim at bringing together researchers interested in the expressiveness of various formal systems and semantic notions, particularly in the field of concurrency. Their focus has traditionally been on the comparison between programming concepts (such as concurrent, functional, imperative, logic and object-oriented programming) and between mathematical models of computation (such as process algebras, Petri nets, event structures, modal logics, and rewrite systems) on the basis of their relative expressive power. The EXPRESS workshop series has run successfully since 1994 and over the years this focus has become broadly construed. The SOS workshops aim at being a forum for researchers, students and practitioners interested in new developments, and directions for future investigation, in the field of structural operational semantics. One of the specific goals of the SOS workshop series is to establish synergies between the concurrency and programming language communities working on the theory and practice of SOS. Since 2012, the EXPRESS and SOS communities have organized an annual combined EXPRESS/SOS workshop on the expressiveness of mathematical models of computation and the formal semantics of systems and programming concepts.

Numerical results for the isolated cross section are presented for for $\vec{p}\vec{p}\rightarrow γ+X$ at RHIC center-of-mass energies with plausible isolation parameters using the most modern polarized parton densities evolved in next-to-leading order QCD. The perturbative stability of the asymmetries and scale dependence of the results are briefly discussed.

description: This survey of monopolies granted by the Crown illustrates respect of the law, and a sensitivity to property rights balanced with recognition of the need for projects to benefit the ‘common weale’. John Gason’s and William Sandys’s patents were the only ones which purported to give authority for the compulsory purchase of land. Gason’s revised patent (1619) specified the method of assessment of damages which had been specified in the first statutory authority for compulsory purchase of land in 1539, and in 1621 statutory authority was sought from Parliament for the compulsory purchase powers granted by Gason’s patents. Sandys’s patent was more problematic, being granted in 1638 during Charles II’s Personal Rule and without the possibility of Parliamentary approval; it had been claimed the previous year that Sandys ‘went about to entitle his Majesty to men’s inheritances’.

description: Evolutionary algorithm is combined with full-potential ab-initio calculations to investigate conformational space of (MoS$_2$)$_n$ and (MoSe$_2$)$_n$ (n=1-10) nanoclusters and to identify the lowest energy structural isomers of these systems. It is argued that within both BLYP and PBE functionals, these nanoclusters favor sandwiched planar configurations, similar to their ideal planar sheets. The second order difference in total energy ($Δ_2$E) of the lowest energy isomers are computed to estimate the abundance of the clusters at different sizes and to determine the magic sizes of (MoS$_2$)$_n$ and (MoSe$_2$)$_n$ nanoclusters. In order to investigate the electronic properties of nanoclusters, their energy gap is calculated by several methods, including hybrid functionals (B3LYP and PBE0), GW approach, and $Δ$scf method. At the end, the vibrational modes of the lowest lying isomers are calculated by using the force constants method and the IR active modes of the systems are identified. The vibrational spectra are used to calculate the Helmholtz free energy of the systems and then to investigate abundance of the nanoclusters at finite temperatures.

description: The interplay between different types of disorder and electron-electron interactions in graphene planes is studied by means of Renormalization Group techniques. The low temperature properties of the system are determined by fixed points where the strength of the interactions remains finite, as in one dimensional Luttinger liquids. These fixed points can be either stable (attractive), when the disorder is associated to topological defects in the lattice or to a random mass term, or unstable (repulsive) when the disorder is induced by impurities outside the graphene planes. In addition, we analyze mid-gap states which can arise near interfaces or vacancies.

description: In dieser explorativen Vorstudie wurde die „Bildungssituation autistischer Kinder und Jugendlicher in Schleswig-Holstein“ untersucht, mit einem Fokus auf die Verbesserung von Unterstützungsstrukturen durch das Landesförderzentrum Autistisches-Verhalten (LFZ-AV). Mittels qualitativer Methoden, darunter Expert:innen- und Fokusgruppeninterviews mit 69 Beteiligten und qualitativer Inhaltsanalyse, identifiziert die Studie drei zentrale Handlungsfelder: Entwicklung autismussensibler inklusiver Schulentwicklung, Professionalisierung der Bildungsakteure im Umgang mit dem Autismus-Spektrum und die Gestaltung inklusiver schulbiographischer Übergänge. Die Ergebnisse zeichnen ein überwiegend positives Bild der Bildungssituation in Schleswig-Holstein, heben jedoch auch die Bedeutung gezielter Verbesserungen und weiterer Forschung in den genannten Bereichen hervor. Die Studie unterstreicht schlussendlich auch die Effektivität und die bundesweite Vorreiterrolle des Beratungssystems durch das Landesförderzentrum Autistisches-Verhalten.

description: L’objectif global du projet « PDB 18 – Der deutsche Brief im 18. Jahrhundert », financé par la Deutsche Forschungsgemeinschaft (DFG) (2022–2025) et porté par trois institutions (Martin-Luther-Universität Halle/Interdisziplinäres Zentrum für die Erforschung der Europäischen Aufklärung, Universitäts- und Landesbibliothek Darmstadt, Berlin-Brandenburgische Akademie der Wissenschaften Berlin) bâtir une base de données numériques permettant l’étude scientifique d’échanges épistolaires durant le XVIIIe siècle à une échelle encore jamais atteinte. Cette base de données réunira à la fois les métadonnées et les textes des lettres allemandes du XVIIIe siècle, le tout accompagné d’un ensemble d’outils de recherche élaborés. D’un point de vue chronologique, le corpus de PDB 18 est constitué de lettres écrites au cours du XVIIIe siècle. Au plan linguistique, il inclut potentiellement toutes les langues. Géographiquement, PDB 18 est destiné à rassembler les lettres écrites ou reçues dans l’espace germanophone du XVIIIesiècle. À terme, l’ambition est de se rapprocher de projets européens voisins et de contribuer ainsi à une potentielle base européenne de lettres pour l’Europe du XVIIIe siècle. Les données numériques relatives aux lettres et aux documents épistolaires sont proposées sur le portail PDB 18 sous différentes formes : (1) métadonnées de base (expéditeur, destinataire, lieu d’envoi et de réception, date, langue, le cas échéant titre du livre ou lieu de conservation avec cote ou numéro d’archive) ; (2) textes numérisés des lettres, transcrits de façon mécanique (OCR) ; (3) images numérisées (du manuscrit ou de l’imprimé) ; (4) éditions numériques et numérisées. À l’issue de la phase actuelle de développement du projet, le portail doit permettre l’accès aux métadonnées d’environ 240 000 lettres provenant d’environ 1100 éditions de lettres imprimées ainsi que de bases de données de lettres.

description: The probability of a projectile nucleon to traverse a target nucleus without interaction is calculated for central Si-Pb collisions and compared to the data of E814. The calculations are performed in two independent ways, via Glauber theory and using the transport code UrQMD. For central collisions Glauber predictions are about 30 to 50% higher than experiment, while the output of UrQMD does not show the experimental peak of beam rapidity particles.

The signatures of conscious access and phenomenology are consistent with large-scale brain communication at criticality

description: Conscious awareness refers to the association of information processing in the brain that is accompanied by subjective, reportable experiences. Current models of conscious access propose that sufficiently strong sensory stimuli ignite a global network of regions allowing further processing. The immense number of possible experiences indicates that brain activity associated with conscious awareness must be highly differentiated. However, information must also be integrated to account for the unitary nature of consciousness. We present a conceptual computational model that identifies conscious access with self-sustained percolation in an anatomical network. We show that if activity propagates at the critical threshold, the amount of integrated information (Phi) is maximal after conscious access, as well as other related markers. We also identify a posterior hotspot of regions with high levels of information sharing during conscious access. Finally, competitive activity spreading qualitatively describes the results of paradigms such as backward masking and binocular rivalry.

description: This article presents a look at ethnicity from the point of view of some important sociological and socioanthropological theories and based on empirical data. One of these theories is Frederick Barth's theory of ethnicity. Everyday life communication and the practice of social interaction are the subjects of the study of ethnomethodology by Harold Garfinkel, and it is an important topic in the dialogic theory of Mikhail Bakhtin. In my study of ethnicity, these approaches, since it is in them that communication is given a primary role, are central and are also reflected in the research method - the method of conversational analysis. Two empirical examples from a rural hospital in Kazakhstan show speech genres in which the ethnic category becomes an integral part of the action and an important means of communication. In this case, the interlocutors resort to the ethnic category in order to clarify the identity of the person they are talking about. In such moments of social interaction, ethnicity is important for interlocutors not in the sense of collective group identity, which divides people into groups, covering up a person's personality, but as information necessary for recognizing and clarifying a specific personality. We are not talking about family, friendship or other close relationships in which the ethnic difference has either long been forgotten or did not matter at all, but about relationships where the interlocutors do not have sufficient information about each other. In this sense, ethnic categories can be compared to a certain extent with the name of a person. The author believes that the use of ethnic categories in everyday language speaks about the similarity of people, about their common speech practices, which are often dominated by stereotypical knowledge, about their common socialization, communication environment, worldview that developed at the beginning of the formation of the (multinational) Soviet state.

description: A study was performed at three mangrove forest areas in the Sundarbandeltaic region in order to check the ratio of salt ions (Na+, K+ and Cl-) presentwithin the excreted salt crystals by the salt glands on the leaves of the blackmangroves (Avicennia spp.), Aegialitis rotundifolia, Acanthus ilicifolius andAegiceras sp. In general, the pre- and postmonsoon periods yielded more sodiumand chloride ions than monsoon, whereas the value for potassium ion showed justthe opposite trend. The results suggested that during monsoon the plants retainedsodium and chloride ions to maintain their osmotic pressure, since the ambientsubstrata received a copious influx of freshwater in the form of rain. Also, theNa+/Cl- ratio seemed to be higher during the monsoon. The cumulative ratio inbetween the cations (Na+, K+) and anion (Cl-) showed resemblance with that ofNa+/Cl-, indicating that the K+/Cl- ratio didn’t have any influence on the net cationand anion excretion.
FCNC, CP violation, and impure Majorana neutrinos

description: The tree level diagonalization of a neutrino mass matrix with both Majorana and Dirac masses is discussed in a general context. Flavor changing neutral currents in such models are inevitable. Rephasing invariant quantities characterizing CP violation in FCNC Fermion-Higgs interactions are identified. At the one loop level, the mass eigenstates become an impure Majorana type. The possibility of a significant change in the mass spectrum for the left-handed neutrinos is explored, with an example of two species of neutrinos. Neutrino oscillations with impure Majorana neutrinos are also discussed.

description: Volatile viscous fluids on partially-wetting solid substrates can exhibit interesting interfacial instabilities and pattern formation. We study the dynamics of vapor condensation and fluid evaporation governed by a one-sided model in a low Reynolds number lubrication approximation incorporating surface tension, intermolecular effects and evaporative fluxes. Parameter ranges for evaporation- dominated and condensation-dominated regimes and a critical case are identified. Interfacial instabilities driven by the competition between the disjoining pressure and evaporative effects are studied via linear stability analysis. Transient pattern formation in nearly-flat evolving films in the critical case is investigated. In the weak evaporation limit unstable modes of finite amplitude non-uniform steady states lead to rich droplet dynamics, including flattening, symmetry breaking, and droplet merging. Numerical simulations show long time behaviors leading to evaporation or condensation are sensitive to transitions between film-wise and drop-wise dynamics.
