description: Bogomolnyi-type bound is constructed for the topological solitons in O(3) nonlinear $σ$ model coupled to gravity with a negative cosmological constant. Spacetimes made by self-dual solutions form a class of Gödel-type universe. In the limit of a spinless massive point particle, the obtained stationary metric does not violate the causality and it is a new point particle solution different from the known static hyperboloid and black hole. We also showed that static Nielsen-Olesen vortices saturate Bogomolnyi-type bound only when the cosmological constant vanishes.

Dark Matter in Galaxies: evidences and challenges

description: The evidence of the phenomenon for which, in galaxies, the gravitating mass is distributed differently than the luminous mass, increases as new data become available. Furthermore, this discrepancy is well structured and it depends on the magnitude and the compactness of the galaxy and on the radius, in units of its luminous size $R_{opt}$, where the measurement is performed. For the disk systems with $-13\geq M_I\geq -24$ all this leads to an amazing scenario, revealed by the investigation of individual and coadded rotation curves, according to which, the circular velocity follows, from their centers out to their virial radii, an universal profile $V_{URC} (r/R_{opt}, M_I)$ function only of the properties of the luminous mass component. Moreover, from the Universal Rotation Curve, so as from many individual high-quality RCs, we discover that, in the innermost regions of galaxies, the DM halo density profiles are very shallow. Finally, the disk mass, the central halo density and its core radius, come out all related to each other and to two properties of the distribution of light in galaxies: the luminosity and the compactness. This phenomenology, being absent in the simplest $ΛCDM$ Cosmology scenario, poses serious challenges to the latter or, alternatively, it requires a substantial and tuned involvement of baryons in the formation of the galactic halos. On the other side, the URC helps to explain the two-accelerations relationship found by McGaugh et al 2016, in terms of only well known astrophysical processes, acting in a standard DM halos + luminous disks scenario

description: We carry out a calculation of the phonon-drag contribution $S_g$ to the thermoelectric power of bulk semiconductors and quantum well structures for the first time using the balance equation transport theory extended to the weakly nonuniform systems. Introducing wavevector and phonon-mode dependent relaxation times due to phonon-phonon interactions, the formula obtained can be used not only at low temperatures where the phonon mean free path is determined by boundary scattering, but also at high temperatures. In the linear transport limit, $S_g$ is equivalent to the result obtained from the Boltzmann equation with a relaxation time approximation. The theory is applied to experiments and agreement is found between the theoretical predictions and experimental results. The role of hot-electron effects in $S_g$ is discussed. The importance of the contribution of $S_g$ to thermoelectric power in the hot-electron transport condition is emphasized.

Pheidole casta Wheeler 1908h: 454.
Types Mus. Comp. Zool. Harvard; Amer. Mus. Nat. Hist.
Etymology Unknown.
Diagnosis A medium-sized, yellow member of the flavens group, whose major is characterized by its elongate head, shallow antennal scrobes, exclusively carinulate cephalic structure, conulate postpetiole, and slightly contrasting brownish spot on the center of the dorsum of the head capsule.
Similar to mera, also of Texas, and distinguished from it by the less bulbous premesonotal profile in dorsal-oblique view, smooth occiput, and longitudinal (not oblique) orientation of the carinulae mesad to the eye. Measurements (mm) Lectotype major: HW 0.82, HL 1.14, SL 0.38, EL 0.14, PW 0.52. Paralectotype minor: HW 0.42, HL 0.48, SL 0.34, EL 0.06, PW 0.26.
color Major: concolorous yellow, with a circular patch of slightly contrasting brownish yellow in center of dorsum of head. Minor: concolorous clear yellow.
Range Southern Texas. Specimens from Estado Mexico (km 127, Highway 57) in the Museum of Comparative Zoology appear to belong to this species, although they are darker in color than the types (brownish yellow), and the sides of the heads of the minors are smooth and shiny.
biology P. casta is evidently a rare species. The type colony was found in a canyon of the Rio Grande, near Langtry, nesting in soil beneath cedars. The only other Texan record is from Cameron Co., about 20 km east of Brownsville (R. E. Gregg). The minor worker from this collection has the head and mesosomal dorsum completely foveolate.

description: Properties of dense quark matter in and out of chemical equilibrium are studied within the SU(3) Nambu-Jona-Lasinio model. In addition to the 4-fermion scalar and vector terms the model includes also the 6-fermion flavour mixing interaction. First we study a novel form of deconfined matter, meso-matter, which is composed of equal number of quarks and antiquarks. It can be thought of as a strongly compressed meson gas where mesons are melted into their elementary constituents, quarks and antiquarks. Strongly bound states in this quark-antiquark matter are predicted for all flavour combinations of quark-antiquark pairs. The maximum binding energy reaches up to 180 MeV per pair for mixtures with about 70% of strange quark-antiquark pairs. Equilibrated baryon-rich quark matter with various flavour compositions is also studied. In this case only shallow bound states appear in systems with a significant admixture (about 40%) of strange quarks (strangelets). Their binding energies are quite sensitive to the relative strengths of scalar and vector interactions. The common property of all these bound states is that they appear at high particle densities when the chiral symmetry is nearly restored. Thermal properties of meso-matter as well as chemically equilibrated strange quark matter are also investigated. Possible decay modes of these bound states are discussed.

description: The metamagnetic transition between the antiferromagnetic and paramagnetic state in UIrGe has been studied at various temperatures by magnetization, heat capacity and magnetocaloric-effect measurements on a single crystal in static and pulsed magnetic fields applied along the orthorhombic b-axis. A first-order transition is observed at temperatures below 13 K and a second-order one at higher temperatures up to the Néel temperature (TN = 16.5 K). The first-order transition is accompanied by a dramatic increase of the Sommerfeld coefficient. Magnetization measurements extended to the paramagnetic range revealed an anomalous S-shape (inflection point at a magnetic field Hm) in magnetization isotherms at temperatures above 13 K and a temperature dependence of susceptibility with a maximum at Tmax well above TN. The lines representing the temperature-induced evolution of Hm and field-induced evolution of Tmax, respectively, are bound for the point in the magnetic phase diagram at which the order of metamagnetic transition changes. A tentative scenario explaining these anomalies by antiferromagnetic correlations or short-range order in the paramagnetic state is discussed.

description: Purpose: To investigate the effect of whole-body low-dose radiation (10 cGy of 6 MV x-rays) given prior to a challenging dose of 2 Gy x-rays on adaptive response in the liver of rats Material and methods: Rats were either irradiated with 10 cGy, 2 Gy or 10 cGy 24 h prior to 2 Gy (10 cGy–2 Gy irradiated). Liver samples were analyzed for apoptosis, caspase-3, Bcl-2, by flow cytometry. DNA damage was determined by alkaline comet assay. The protein damage, lipid damage, and expression of endogenous antioxidants, Il-1β, Il-6, and TNF-α were determined by ELISA. Results: An increase in apoptosis paralleled with increase in DNA damage and expression of Il-1β, Il-6, and TNF-α, protein oxidation, and lipid peroxidation were detected in all irradiated groups. The irradiated rats with 10 cGy–2 Gy and the 2 Gy-irradiated showed the highest effect. The increase in oxidative damage of protein and lipid was accompanied with depletion of endogenous antioxidants. In all cases, the10 cGy–2 Gy irradiated group showed similar or higher effect than the 2 Gy-irradiated group. Conclusions: Under the present experimental conditions, There is no evidence that 10 cGy-irradiation protected the liver cells against a subsequent higher dose. The significant effect of 10 cGy-irradiation emphasizes the low-dose radiation-associated risk.

description: In this manuscript we identify the main differences between the effects of Kramers symmetry on the systems with even and odd number of electrons, the ways how the aforementioned symmetry affects the structure of the Conical Seams (CSs), and how it shows up in semiclassical propagation of nuclear wavepackets, crossing the CSs. We identify the topological invariants, associated with CSs, in three cases: even and odd number of electrons with time-reversal symmetry, as well as absence of the latter. We obtain asymptotically exact semiclassical analytical solutions for wavepackets scattered on a CS for all three cases, identify topological features in a non-trivial shape of the scattered wavepacket, and connect them to the topological invariants, associated with CSs. We argue that, due to robustness of topology, the non-trivial wavepacket structure is a topologically protected evidence of a wavepacket having passed through a CS, rather than a feature of a semiclassical approximation.

Control of the helicity of high-order harmonics generated by bicircular field

description: High-order harmonics generated by bicircular laser field have helicities which alternate between $+1$ and $-1$. In order to generate circularly polarized high-harmonic pulses, which are important for applications, it is necessary to achieve asymmetry in emission of harmonics having opposite helicities. We theoretically investigated a wide range of bicircular field component intensities and found areas where both the harmonic intensity is high and the helicity asymmetry is large. We investigated the cases of $ω$--$2ω$ and $ω$--$3ω$ bicircular fields and atoms having the $s$ and $p$ ground states, exemplified by He and Ne atoms, respectively. We have shown that for He atoms strong high harmonics having positive helicity can be generated using $ω$--$3ω$ bicircular field with a much stronger second field component. For Ne atoms the helicity asymmetry can be large in a wider range of the driving field component intensities and for higher harmonic orders. For the stronger second field component the harmonic intensity is higher and the helicity asymmetry parameter is larger for higher harmonic orders. The results for Ne atoms are illustrated with the parametric plots of elliptically polarized attosecond high-harmonic field.

description: In a realistic application of the SPA + RPA theory for calculation of the nuclear level densities we find that quantal fluctuation corrections (RPA) are important even up to temperature $T = 2.0 MeV$. This leads to a good agreement between calculated numbers and the available experimental data for $^{104}Pd$ and $^{114}Sn$, particularly the excitation energy ($E^*$) dependence. Furthermore, we also argue that $a=S^2/4E^*$ is the only correct definition of the level density parameter in the present context which is also consistent with the Bethe like level density formula.

description: The description of very high energy proton-proton cross sections in terms of a `black disc' with an `edge' allows of a simple generalization to highest energy proton-nucleus cross sections. This results in a leading $ln^2W$ term and a $ln\, W$ term whose coefficient depends linearly on the radius of the nucleus ($W$ the c.m. energy). The necessary parameters are determined from the fits to p-p data. Since the coefficient of the $ln W$ term is rather large, it is doubtful that the regime of $ln^2W$ dominance can be reached with available energies in accelerators or cosmic rays. However, the $ln W$ term can be relevant for highest energy cosmic rays in the atmosphere, where a large increase for the cross section on nitrogen is expected. Tests of the theory should be possible by studying the coefficient of $ln W$ at p-nucleus colliders.

In this model the contribute of a given spin to the total energy has only two possible values and depends on the number of parallel spins among its nearest and next to the nearest neighbors.

Anomalous Flavor U(1): Predictive Texture For Bi-maximal Neutrino Mixing

description: We present a scenario which naturally provides bi-maximal neutrino mixings for a simultaneous explanation of the recent atmospheric and solar neutrino data. A crucial role is played by an anomalous flavor ${\cal U}(1)$ symmetry, which is also important for a natural understanding of charged fermion mass hierarchies and magnitudes of the CKM matrix elements. Within MSSM the solar neutrino problem can be resolved either through vacuum oscillations or the large mixing angle MSW solution. In supersymmetric GUTs such as SU(5) and SO(10) the MSW solution is realized. If the flavor ${\cal U}(1)$ also mediates supersymmetry breaking, the vacuum solution in MSSM is eliminated, and only the large mixing angle MSW solution survives.

Liver samples were analysed for apoptosis,caspase-3, Bcl-2, by flow cytometery. DNA damage was determined by alkaline comet assay. The protein damage, lipid damage, and expression of endogenous antioxidants, Il-1β, Il-6, and TNF-α were determined by ELISA. Results: An increase in apoptosis paralleled with increase in DNA damage and expression of Il-1β, Il-6, and TNF-α, protein oxidation and lipid peroxidation were detected in all irradiated groups. The irradiated rats with 10cGy-2Gy and the 2Gy-irradiated showed the highest effect. The increase in oxidative damage of protein and lipid was accompanied with depletion of endogenous antioxidants. In all cases, the10cGy-2Gy irradiated group showed similar or higher effect than the 2Gy-irradiated group. Conclusions: Under the present experimental conditions, There is no evidence that 10cGy-irradiation protected the liver cells against a subsequent higher dose. The significant effect of 10 cGy-irradiation emphasizes the low-dose radiation associated risk.

description: Digitally managing punctuation in the editions of medieval manuscripts is one of those issues that initially look like minor details, but later reveal themselves as a tangled web of problems spanning from computer science (how to represent punctuation signs?) to philology (what types of signs do exist?) through epistemology (is the processing of punctuation a mere technical transformation or a valuable part of the scholarship?). The aim of this paper is to address the theoretical aspects of these questions and their practical implications, providing a couple of solutions fitting the paradigms and the technologies of the TEI. The debate on how to deal with medieval punctuation is a long and still open one. Following Contini (1992), the interpretative edition of a manuscript is the translation of a historically attested system into another system. Accordingly, the philologist should recognize the punctuation system of the manuscript and convert it into a modern one. There are, however, no established universal methods for doing so; most of this work is left to the experience (and taste) of the scholar. In fact, editors often substitute the original punctuation with a modern one. This improves the text readability, but often leads to a loss of textual information. In this paper we describe how we dealt with the encoding and transformation of the punctuation signs in some German manuscripts of Marco Polo’s work. Technically, we implemented a set of general rules (as XSLT templates) and various ad-hoc exceptions (as descriptive instructions in XML attributes). In addition to this, we discuss the philological foundation of this method and, contextually, we address the topic of the transformation of a single original source into different transcriptions: from a “hyperdiplomatic” edition to an interpretative one, going through a spectrum of intermediate levels of normalization. We also reflect on the separation between transcription and analysis, as well as on the role of the editor when the edition is the output of a semi-automated process.

description: Pheidole cerina new species
Types INBio.
etymology L cerina, wax-colored, yellowish, referring to the color.
Diagnosis a relatively large species for the flavens group, with yellow to brown major and minor. Similar to amabilis of Costa Rica but differing in the major in the reduced propodeal spines, which point posteriorly (versus vertically in amabilis); in the well-developed mesonotal convexity, in the longer cephalic carinulae; in the more extensive carinulae of the pronotal dorsum; and in much longer antennal scapes of the minor (SL/HW 1.14, versus 1.0 in amabilis). P. cerina, in the major mesonotal convexity and longer minor scapes, appears intermediate between the flavens and punctatissima groups.
See also the less similar grex, mixteca, and morelosana.
Measurements (mm) Holotype major: HW 1.14, HL 1.74, SL 0.64, EL 0.16, PW 0.56. Paratype minor: HW 0.44, HL 0.50, SL 0.50, EL 0.06, PW 0.30.
Color Major: body, mandibles, and antennae concolorous reddish yellow, legs medium yellow.
Minor: concolorous light-medium yellow. I have also seen two dark series from the type locality, with medium brown bodies and yellow appendages.
Range Known only from the type locality.
Biology Three series for which data are available come from litter samples taken in wet forest.

description: A proof is presented for the absence of gap for spin $1/2$ ladders with an odd number of legs, in the infinite leg length limit. This result is relevant to the current discussion of coupled one--dimensional spin systems, a physical realization of which are vanadyl pyrophosphate, (VO)$_2$P$_2$O$_7$, and stoichiometric Sr$_{n-1}$ Cu$_{n+1}$ O$_{2n}$ (with $n=3,5,7,9,\dots$).

description: L. P. Belluce, A. Di Nola and B. Gerla established a connection between MV-algebras and (dually) lattice ordered semirings by means of so-called coupled semirings. A similar connection was found for basic algebras and semilattice ordered right near semirings by the authors. The aim of this paper is to derive an analogous connection for orthomodular lattices and certain semilattice ordered near semirings via so-called coupled right orthosemirings.
The light speed vs the observer: the Kennedy-Thorndike test from GRAAL-ESRF

description: High precision tests of the light speed constancy for all observers as of empirical basis of the Special Relativity have continuously been among the goals of advanced experimental studies. Based on the Compton Edge method proposed by us [1], a constraint on the one-way light speed isotropy and the Lorentz invariance violation has been obtained at the dedicated GRAAL experiment at European Synchrotron Radiation Facility (ESRF, Grenoble) [2-5]. Using the GRAAL's data we now get a new constraint on one of key tests of Special Relativity - the Kennedy-Thorndike experiment [6] - in probing the light speed invariance with respect to the velocity of the observer (apparatus). Our analysis takes advantage of GRAAL's setup where two separate energy scales are involved: first, via the position of the Compton Edge determining the light speed in the reference frame of incident 6 GeV electrons within the tagging system, second, in the calorimeter via the 1.27 MeV photons of the ^22 Na source. The two energy scales are engaged to each other through production of $η$ mesons by tagged laser Compton backscattered $γ$-rays. Accuracy of the calibration and stability of energies reached in each section enable us to obtain the limit 7 10^-12 for the Kennedy-Thorndike test, which improves the currently existing limits by three orders of magnitude.

description: In this work we use matrix models to study the problem of strength distributions. This is motivated by noticing near exponential fall offs of strengths in calculated magnetic dipole excitations. We emphasize that the quality of the exponential fall offs depend on the parameters in our matrices, especially the relative size of the couplings to the unperturbed level separations. We also find a matrix for which all transitions vanish.
Inflation and Monopoles in Supersymmetric SU(4)_c x SU(2)_L x SU(2)_R

description: We show how hybrid inflation can be successfully realized in a supersymmetric model with gauge group G_{PS}= SU(4)_c x SU(2)_L x SU(2)_R. By including a non-renormalizable superpotential term, we generate an inflationary valley along which G_{PS} is broken to the standard model gauge group. Thus, catastrophic production of the doubly charged magnetic monopoles, which are predicted by the model, cannot occur at the end of inflation. The results of the cosmic background explorer can be reproduced with natural values (of order 10^{-3}) of the relevant coupling constant, and symmetry breaking scale of G_{PS} close to 10^{16} GeV. The spectral index of density perturbations lies between unity and 0.9. Moreover, the mu-term is generated via a Peccei-Quinn symmetry and proton is practically stable. Baryogenesis in the universe takes place via leptogenesis. The low deuterium abundance constraint on the baryon asymmetry, the gravitino limit on the reheat temperature and the requirement of almost maximal mu neutrino - tau neutrino mixing from SuperKamiokande can be simultaneously met with mu-neutrino, tau-neutrino and heaviest Dirac neutrino masses determined from the large angle MSW resolution of the solar neutrino problem, the SuperKamiokande results and SU(4)_c symmetry respectively.

Pheidole chalca Wheeler 1914c: 44.
Types Mus. Comp. Zool. Harvard.
Etymology Presumably from Gr chalkos, copper, alluding to the body color.
Diagnosis A small-medium species, with angulate postpetiole and bicolorous head in the major. Similar to chalcoides, but distinguished in the major by the smooth humerus, which is less prominent in dorsal-oblique view; broader, angular-sided postpetiolar node; and yellow occiput; and in the minor by the unarmed humerus and smooth pronotal dorsum. Also similar but less so to arhuaca, caulicola, mincana, sagana, schmalzi, and tragica, differing in details of body shape, and sculpture as illustrated, and color.
Measurements (mm) Lectotype major: HW 1.04, HL 1.24, SL 0.54, EL 0.14, PW 0.52. Paralectotype minor: HW 0.52, HL 0.60, SL 0.50, EL 0.12, PW 0.38.
color Major: anterior third of head and occiput yellow, remainder of head brown; body yellowish to light brown;
appendages light yellow.
Minor: brownish yellow.
Range Hidalgo and Veracruz, Mexico.
biology Mann (in Wheeler 1914c) found numerous small colonies in oak-pine woodland near Molino Guerrero, an ore mill on the eastern slope of the mountain range east of Pachuca; they were nesting under stones. I found a nest of several chambers about 15 cm below the surface in the dense clay soil of Liquidambar woods adjacent to a meadow at approximately 1700 m on the south slope of Pico Orizaba. Workers were foraging along an adjacent trail. Sexual pupae were in the nest on 23 August.

description: We investigate the leptogenesis via decays of heavy Majorana neutrinos which are produced non-thermally in inflaton decays. We make a comprehensive study on the leptogenesis assuming various supersymmetric (SUSY) models for hybrid, new and topological inflations. For an estimation of the lepton asymmetry we adopt the Froggatt-Nielsen mechanism for mass matrices of quarks and leptons. We find that all of these models are successful to produce the lepton asymmetry enough to explain the baryon number in the present universe. Here we impose low reheating temperatures such as $T_R \lesssim 10^8$ GeV in order to suppress the abundance of gravitinos not to conflict with the big-bang nucleosynthesis. Furthermore, we find that the leptogenesis works very well even with $T_R \simeq 10^{6}$ GeV in the SUSY hybrid or new inflation model. It is known that such a reheating temperature is low enough to suppress the abundance of gravitinos of mass $m_{3/2} \simeq 100$ GeV--1 TeV. Thus, the leptogenesis is fully consistent with the big-bang nucleosynthesis in a wide region of the gravitino mass.

description: In searching for drugs from natural product scaffolds has gained interest among researchers. In this study, a series of twelve halogenated thiourea (ATX 1-12) via chemical modification of aspirin (a natural product derivative) and evaluated for cytotoxic activity against nasopharyngeal carcinoma (NPC) cell lines, HK-1 via MTS-based colorimetric assay. The cytotoxicity studies demonstrated that halogens at meta position of ATX showed promising activity against HK-1 cells (IC50 value ≤15 µM) in comparison to cisplatin, a positive cytotoxic drug (IC50 value =8.9 ± 1.9 µM). ATX 11, bearing iodine at meta position, showed robust cytotoxicity against HK-1 cells with an IC50 value of 4.7 ± 0.7 µM. Molecular docking interactions between ATX 11 and cyclooxygenase-2 demonstrated a robust binding affinity value of −8.1 kcal/mol as compared to aspirin’s binding affinity value of −6.4 kcal/mol. The findings represent a promising lead molecule from natural product with excellent cytotoxic activity against NPC cell lines.
