description: Pheidole floridana Emery
Pheidole flavens subsp. floridana Emery 1895d: 293. Raised to species level by Pergande 1896: 883. Syn.: Pheidole lauta Wheeler 1908h: 470, synonymy by Gregg 1959: 21.
types Mus. Comp. Zool. Harvard; Mus. Civ. Stor. Nat. Genova.
Etymology Named after the state of origin.
Diagnosis Nearly identical with bilimeki and its Neotropical variants, distinguished as follows.
Major: foveolation on dorsum of head very fine; first gastral tergite smooth and shiny; humerus less prominent in
dorsal-oblique view.
Minor: antennal scapes relatively short, just reaching or barely surpassing the occipital corner; first gastral tergite smooth and shiny, with at most a light shagreening at the base of the tergite.
Both castes are consistently yellow. P. floridana is very close to bilimeki, and also to stomachosa of Jamaica, which coexists on the island with bilimeki. P. stomachosa is distinguished from both bilimeki and floridana by the head and pronotum of the minor being smooth and shiny (q.v.).
Measurements (mm) Lectotype major: HW 0.92, HL 1.00, SL 0.44, EL 0.10, PW 0.46. Paralectotype minor: HW 0.44, HL 0.52, SL 0.42, EL 0.06, PW 0.30. Color Major and minor: concolorous yellow.
range P. floridana has been recorded by Stefan Cover (personal communication) from the coastal plain of North Carolina south to the Florida Keys and west to central Texas (Austin and surrounding area), thence south into Mexico.
biology At Bald Point, Franklin Co., Florida, I found colonies nesting at a roadside in open sandy soil; and in Mobile, Alabama (in 1942) what was probably this species nesting beneath a whiskey bottle in a vacant lot. Winged reproductives have been found in nests during September and October. Stefan Cover (personal communication) reports that floridana "occurs in a variety of woodland habitats, nests in soil, litter, and rotten wood, and in both xeric and mesic situations. Colonies are monogynous, may contain 1000 or more ants, and are sometimes polydomous. The species is omnivorous, but does not appear to harvest seeds."
Figure Upper: lectotype, major (damaged specimen; pilosity added from a fresh specimen); the upper dorsal-oblique profile of mesosoma is the lectotype, and the lower profde is a major from Sarasota, Florida. Lower: paralectotype, minor (damaged specimen; pilosity added from a fresh specimen). Scale bars = 1 mm.

Softly Broken Supersymmetric Gauge Theories through Compactifications
Creators: name: Takenaga, K.
Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Effects of boundary conditions of fields for compactified space directions on the supersymmetric gauge theories are discussed. For general and possible boundary conditions the supersymmetry is explicitly broken to yield universal soft supersymmetry breaking terms, and the gauge symmetry of the theory can also be broken through the dynamics of non-integrable phases, depending on number and the representation under the gauge group of matters. The 4-dimensional supersymmetric QCD is studied as a toy model when one of the space coordinates is compactified on $S^1$.

description: At a critical spinodal in-plane stress $τ_{C}$ a planar crystalline graphene layer becomes mechanically unstable. We present a model of the critical behavior of the membrane area near $τ_{C}$ and show that it is in complete agreement with path-integral simulations and with recent experiments based on interferometric profilometry and Raman spectroscopy. Close to the critical stress, $τ_{C}$, the in-plane strain behaves as $\left(τ_{C}-τ\right)^{1/2}$ for $τ

description: Overexpression of Rubisco small subunit (RbcS) of C4 plant, sorghum (sorghum bicolor) was shown to enhance the catalytic turnover rate (k cat) of Rubisco in rice (Oryza sativa). In this study, the effects of other Rubisco small subunits of C4 plants, Napier grass (Pennisetum purpureum) and guinea grass (Megathyrsus maximus) on kinetic properties of Rubisco in rice were studied. The expression levels of Napier grass RbcS (NgRbcS) and guinea grass RbcS (GgRbcS) proteins accounted for 41% and 45% of total RbcS, respectively in homozygous overexpression lines. The k cat and K m for CO2 (Kc) of Rubisco were increased in all transgenic lines. Interestingly, the k cat was markedly higher in NgRbcS homozygous line, whereas K c was notably higher in GgRbcS homozygous line. Although its effects depend on species, these results suggest that the introduction of C4 RbcS are effective approaches to alter the catalytic properties of Rubisco in rice. GgRbcS: guinea grass RbcS; K c: K m for CO2; k cat: catalytic turnover rate; NpRbcS: Napier grass RbcS; RbcL: Rubisco large subunit; RbcS: Rubisco small subunit; Sc/o: CO2/O2 specificity.

description: One possible ramification of unified theories of nature such as string theory that may underlie the conventional standard model is the possible spontaneous breakdown of Lorentz and CPT symmetry. In this talk, the formalism for inclusion of such effects into a low-energy effective field theory is presented. An extension of the standard model that includes Lorentz- and CPT-breaking terms is developed. The restriction of the standard model extension to the QED sector is then discussed.

Investigation on the Ground States of a Model Thin-Film Superconductor on a Sphere

Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We consider the problem of finding the ground state of a model type-II superconductor on the two-dimensional surface of a sphere, penetrated by $N$ vortices. Numerical work shows the ground states to consist of a triangular network of the vortices with twelve five-coordinated centres. Values of $N$ are found with particularly low energy ground states, due to structures of high symmetry. The large $N$ limit is treated within elasticity theory to compare with the triangular vortex lattice that forms the ground state on an infinite flat plane. Together with numerical work this demonstrates that the thermodynamic limit $N\rightarrow\infty$ of the spherical system remains different from the flat plane due to the presence of twelve disclination defects.

description: In many historical centers in Europe, stone masonry buildings are part of building aggregates, which developed when the layout of the city or village was densified. The analysis of such building aggregates is very challenging and modelling guidelines missing. Advances in the development of analysis methods have been impeded by the lack of experimental data on the seismic response of such aggregates. The SERA project AIMS (Seismic Testing of Adjacent Interacting Masonry Structures) provides such experimental data by testing an aggregate of two buildings under two horizontal components of dynamic excitation.
 With the aim to advance the modelling of unreinforced masonry aggregates, a blind prediction competition is organized before the experimental campaign. Each group is provided a complete set of construction drawings, material properties, testing sequence and the list of measurement to be reported.

description: The present status and recent developments in the theory of light hydrogenic atoms, electronic and muonic, are extensively reviewed. The discussion is based on the quantum field theoretical approach to loosely bound composite systems. The basics of the quantum field theoretical approach, which provide the framework needed for a systematic derivation of all higher order corrections to the energy levels, are briefly discussed. The main physical ideas behind the derivation of all binding, recoil, radiative, radiative-recoil, and nonelectromagnetic spin-dependent and spin-independent corrections to energy levels of hydrogenic atoms are discussed and, wherever possible, the fundamental elements of the derivations of these corrections are provided. The emphasis is on new theoretical results which were not available in earlier reviews. An up-to-date set of all theoretical contributions to the energy levels is contained in the paper. The status of modern theory is tested by comparing the theoretical results for the energy levels with the most precise experimental results for the Lamb shifts and gross structure intervals in hydrogen, deuterium, and helium ion $He^+$, and with the experimental data on the hyperfine splitting in muonium, hydrogen and deuterium.

description: The leading-particle effect and the factorization property of the scattering amplitude in the impact parameter space are used to study semiclassical production of pions in the central region. The mechanism is related to the isospin-uniform solution of the nonlinear $ σ$-model coupled to quark degrees of freedom. The multipion exchange potential between two quarks is derived. It is shown thatthe soft chiral pion bremsstralung also leads to anomalously large fluctuations in the ratio of neutral to charged pions. We show that only direct production ofpions in the form of an isoscalar coherent pulse without isovector pairs can lead to large neutral-charged fluctuations.

description: Dimers and trimers of carbonyl sulfide (OCS) molecules embedded in helium nanodroplets are aligned by a linearly polarized 160 ps long moderately intense laser pulse and Coulomb exploded with an intense 40 fs long probe pulse in order to determine their structures. For the dimer, recording of 2D images of OCS$^+$ and S$^+$ ions and covariance analysis of the emission directions of the ions allow us to conclude that the structure is a slipped-parallel shape similar to the structure found for gas phase dimers. For the trimer, the OCS$^+$ ion images and corresponding covariance maps reveal the presence of a barrel-shaped structure (as in gas phase) but also other structures not present in the gas phase, most notably a linear chain structure.

description: We consider a series of duality transformations that leads to a constant shift in the harmonic functions appearing in the description of a configuration of branes. This way, for several intersections of branes, we can relate the original brane configuration which is asymptotically flat to a geometry which is locally isometric to adS_k x E^l x S^m. These results imply that certain branes are dual to supersingleton field theories. We also discuss the implications of our results for supersymmetry enhancement and for supergravity theories in diverse dimensions.

description: The dynamics of solid-liquid interfaces controlled by solute precipitation and/or dissolution due to the chemical reaction at the interface were computed in two dimensions using a phase field models. Sharp-interface asymptotic analysis demonstrated that the phase field solutions should converge to the proper sharp-interface precipitation/dissolution limit. For the purpose of comparison, the numerical solution of the sharp-interface model for solute precipitation/dissolution was directly solved using a level set method. In general, the phase field results are found in good agreement with the level set results for all reaction rates and geometry configurations investigated. Present study supports the applications of both methods to more complicated and realistic reactive systems, including the nuclear waste release and mineral precipitation and dissolution.
Coulomb-interaction-induced Majorana edge modes in nanowires

description: We show that Majorana edge modes appear in a strongly correlated phase of semiconducting nanowires with discrete rotational symmetry in the cross section. These modes exist in the absence of spin-orbit coupling, magnetic fields and superconductivity. They appear purely due to the combination of the three-dimensional Coulomb interaction and orbital physics, which generates a fermionic condensate exhibiting a topological ground state degeneracy in a sector of the spectrum which is gapped to continuum modes. The gap can be comparable in magnitude to the topological superconducting gap in other solid-state candidate systems for Majorana edge modes, and may similarly be probed via tunnel spectroscopy.

description: Mean field approximation is a popular method to study the behaviour of stochastic models composed of a large number of interacting objects. When the objects are asynchronous, the mean field approximation of a population model can be expressed as an ordinary differential equation. When the objects are (clock-) synchronous the mean field approximation is a discrete time dynamical system. We focus on the latter.We study the accuracy of mean field approximation when this approximation is a discrete-time dynamical system. We extend a result that was shown for the continuous time case and we prove that expected performance indicators estimated by mean field approximation are $O(1/N)$-accurate. We provide simple expressions to effectively compute the asymptotic error of mean field approximation, for finite time-horizon and steady-state, and we use this computed error to propose what we call a \emph{refined} mean field approximation. We show, by using a few numerical examples, that this technique improves the quality of approximation compared to the classical mean field approximation, especially for relatively small population sizes.

description: Theoretical investigations of the hyperfine structure of the hydrogen molecular ion (one electron and two protons) are discussed. The nuclear spin-rotation interaction has been found to be of the same sign as in the hydrogen molecule and the hyperfine transition frequencies can be accurately predicted. With measurements of the hyperfine structure of the deuterium molecular ion (or of HD+) it should be possible to obtain a value of the deuteron quadrupole moment that could be compared with the values obtained from the deuterium molecule and from nuclear theory.

We also predict that nuclear enhancement effects at RHIC energies can be large.

description: We present a Hamiltonian approach for the wellknown Eigen model of the Darwin selection dynamics. Hamiltonization is carried out by means of the embedding of the population variable space, describing behavior of the system, into the space of doubled dimension by introducing additional dynamic variables. Besides the study of the formalism, we try to interpret its basic elements (phase space, Hamiltonian, geometry of solutions) in terms of the theoretical biology. A geometric treatment is given for the considered system dynamics in terms of the geodesic flows in the Euclidean space where the population variables serve as curvilinear coordinates. The evolution of the distribution function is found for arbitrary distributed initial values of the population variables.

These two-electron states are carried by special compact configurations of four single-electron levels. The existence of these states does not require phonon mediation, and is facilitated by the disorder-induced potential relief and by the electron-electron repulsion only. The density of two-electron states is estimated and their evolution with the magnetic field is discussed.

description: Discovering and clustering subspaces in high-dimensional data is a fundamental problem of machine learning with a wide range of applications in data mining, computer vision, and pattern recognition. Earlier methods divided the problem into two separate stages of finding the similarity matrix and finding clusters. Similar to some recent works, we integrate these two steps using a joint optimization approach. We make the following contributions: (i) we estimate the reliability of the cluster assignment for each point before assigning a point to a subspace. We group the data points into two groups of "certain" and "uncertain", with the assignment of latter group delayed until their subspace association certainty improves. (ii) We demonstrate that delayed association is better suited for clustering subspaces that have ambiguities, i.e. when subspaces intersect or data are contaminated with outliers/noise. (iii) We demonstrate experimentally that such delayed probabilistic association leads to a more accurate self-representation and final clusters. The proposed method has higher accuracy both for points that exclusively lie in one subspace, and those that are on the intersection of subspaces. (iv) We show that delayed association leads to huge reduction of computational cost, since it allows for incremental spectral clustering.

description: [fol. 98] Je puis enfin, M. et cher confrère, vous renvoyer l’ouvrage de Sertorius Ursatus et je profite avec empressement du départ de M. La Beaume pour qu’il vous soit rendu surement. Je vous fais mille remerciements de la complaisance que vous avez eue de me le prêter. J’en ai eu tout le soin possible. Vous devez trouver que je vous l’ai gardé bien longtemps, mais vous en serez moins surpris lorsque je dirai que j’ai eu la patience de le copier presque d’un bout à l’autre. L’entreprise m’effraya d’abord, mais je me décidai parce que je vis qu’il m’était absolument nécessaire puisqu’il devait faire la base du mien. Aujourd’hui, je pourrais le pousser un peu plus vite parce que je me trouve bien fourni de matériaux. J’ai commencé à les employer. Si mon ouvrage voit jamais le jour et s’il paraît un peu renforcé, ce sera à vous qu’il en aura toute l’obligation.
Il n’a point paru d’autres volumes de l’histoire du Dauphiné. M. de Faujas est trop occupé du [fol. 98v] ballon aérostatique pour penser à l’autre ouvrage. Il faut convenir qu’il est bien glorieux pour le Vivarais qu’on y ait trouvé le véritable moyen de s’élever en l’air qu’on cherchait depuis si longtemps. Mais de ce premier pas jusqu’à celui de pouvoir diriger sa marche dans les airs, il y a encore loin. Je ne doute pas cependant qu’on y réussisse. On en est trop occupé.
Comment vous portez-vous ? Il y a un temps infini que je n’ai pas reçu de vos nouvelles. Pour peu que vos douleurs vous empêchent de me répondre, gardez-vous de le faire. Je serais au désespoir qu’elles augmentassent à mon occasion. M. de la Beaume m’en donnera. Il est fort empressé de vous voir.
J’ai l’honneur d’être avec des sentiments bien sincères d’estime et de reconnaissance, Monsieur, votre très humble et très obéissant serviteur.

description: Nature displays a vast array of geometrically ordered systems, at nearly every length scale. This is especially true in soft matter and biological physics, where geometric
considerations help us understand problems from the assembly of helical proteins to the morphogenesis of
flower petals. In many cases, this geometric ordering is
mechanical in origin: energy must be expended for objects to stretch, bend, and deform. This thesis explores some of the conclusions that can be drawn from this simple observation.

description: Definitely, an affirmative answer to this question would have implications of fundamental importance for astrophysics (a new class of compact stars), and for the physics of strong interactions (deconfined phase of quark matter, and strange matter hypothesis). In the present work, we use observational data for the newly discovered millisecond X-ray pulsar SAX J1808.4-3658 and for the atoll source 4U 1728-34 to constrain the radius of the underlying compact stars. Comparing the mass-radius relation of these two compact stars with theoretical models for both neutron stars and strange stars, we argue that a strange star model is more consistent with SAX J1808.4-3658 and 4U 1728-34, and suggest that they are likely strange star candidates.

description: The classical approach to linking lattice dynamics properties to continuum equations of motion, the "method of long waves," is extended to include higher order terms. The additional terms account for non-local and non-linear effects. In the first part of the article, the derivation is made within the harmonic approximation for the perfect lattice response. Higher order terms are included in the continuum equation of motion to account for non-linear dispersion effects. Wave propagation coefficients as well as fourth order dispersion coefficients are obtained. In the second part, the lattice anharmonicity is considered and nonlinear macroscopic equations of motion are obtained within the local approximation. Both continuum solutions are particularized to the one-dimensional case and are compared with the lattice response in order to establish the accuracy of the approximation.

description: The development of deepfake technology is now threatening the integrity and security of social media platforms. Deepfakes, which create incredibly lifelike but phony audio, video, and image content using sophisticated artificial intelligence (AI) techniques, can cause anything from political influence and disinformation to reputational harm and privacy violations. This paper focuses on the primary barriers to detecting deepfakes, including the intricacy of generative AI models, the rate at which content circulates, and the limitations of current detection technologies. It also investigates innovative solutions, including AI-driven detection algorithms, blockchain for content verification, and user education initiatives. The essay emphasizes the need for a comprehensive approach that integrates technical, legal, and social strategies to lessen the risks posed by deepfakes on social media platforms. Finally, it identifies future research areas, including developing stronger detection systems and the ethical implications of automated deepfake detection.

Tilt-induced kink in the plasmon dispersion of two-dimensional Dirac electrons

description: The list of two dimensional Dirac systems with a tilt in their Dirac cone spectrum is expanding, and now in addition to organic system $α$(BEDT-TTF)$_2$I$_3$ includes the two dimensional $8Pmmn$-borophene sheet, which allows for controlled doping by the gate voltage. We analytically calculate the polarization function of tilted Dirac cone for arbitrary tilt parameter, $0\le η<1$, and arbitrary doping. This enables us to find two interesting plasmonic effects solely caused by the tilt: (i) In addition to the standard plasmon oscillations, strong enough tilt, induces an additional linearly dispersing overdamped branch of plasmons, which is strongly Landau damped due to overlap with a large density of intra-band free particle-hole (PH) excitations. (ii) There appears a kink in the plasmon dispersion for any non-zero tilt parameter. The kink appears when the plasmon branch enters the inter-band continuum of PH excitations. This kink becomes most manifest for wave vectors perpendicular to the tilt direction and fades away by approaching the tilt direction. Experimental measurement of the wave vector and energy of the plasmonic kink, when combined with our analytic formula for the kink energy scale, allows for a direct experimental measurement of the tilt parameter.

description: RESUMO

O uso disseminado de máscaras pela população de modo geral durante a pandemia de Covid-19 levantou várias questões importantes, incluindo a possibilidade de contaminação das máscaras utilizadas e o risco à saúde da população. Esse estudo objetivou avaliar a contaminação microbiológica e o risco à saúde de máscaras cirúrgicas por mesófilos aeróbios, enterobactérias e Sthaphylococcus aureus. Voluntários foram selecionados para utilizarem máscaras cirúrgicas, simulando o uso que elas fizeram de máscaras durante a pandemia de Covid-19. A partir de amostragem feita em cada máscara, foi realizada a contagem de mesófilos aeróbios, enterobactérias e de Sthaphylococcus aureus. Com os resultados desse estudo foi possível obter informações importantes a cerca da contaminação microbiológica e o risco à saúde das máscaras cirúrgicas usadas para prevenir a transmissão do vírus Sars-CoV-2 causador da Covid-19. A maioria das amostras avaliadas apresentou contaminação por todos os grupos de microrganismos pesquisados, sendo, portanto, indicativo de possível contaminação do ar por microrganismos patogênicos de transmissão aérea, sugerindo que os dados obtidos possam ser utilizados para orientar políticas públicas de controle de infecções e proteção à saúde da população.
