description: We study signatures of heavy Majorana neutrinos at e- gamma colliders. Since these particles violate lepton number, they can give rise to the reactions e- gamma -> W- W- e+ and e- gamma -> W+ mu- mu- nu. The Standard Model background contains extra light neutrinos that escape detection, and can be reduced significantly after imposing appropriate kinematical cuts. We analyze the physics potential of an e- gamma collider, with centre of mass energies sqrt(s) = 0.5--1 TeV and a total integrated luminosity of 100/fb, for detecting heavy Majorana neutrinos with masses mN = 100--400 GeV. Assuming that heavy neutrinos couple predominantly to one lepton flavour at a time, we find that 10 expected background-free events can be established for |B_{eN}| >~ 4.6 x 10^{-3}. Instead, if no signal is observed, this will imply that |B_{eN}| ~< 2.7 x 10^{-3} and |B_{μN}| ~< 0.05 at the 90% confidence level.

description: The directional total emittance at 283 Κ of three hard-coated glasses of medium to low emittance was measured over the angular range 10° to 84°. The measured values at 10° a r e 0.137 ± 0.003, 0.309 ± 0.006, 0.630 ± 0.008. The angular variadon correlates with these values: The lowest emittance glass is quasi metallic; the highest emittance glass is quasi dielectric; the intermediate glass is weakly metallic. Directional data are needed for the most accurate type of modelling of the thermal behaviour of glazing, and can also be used to refme the correction tables needed to obtain the corrected emittance from the normal emittance.

description: Using scattering amplitudes, we obtain the potential contributions to conservative binary dynamics in general relativity at fourth post-Minkowskian order, ${\cal O}(G^4)$. As in previous lower-order calculations, we harness powerful tools from the modern scattering amplitudes program including generalized unitarity, the double copy, and advanced multiloop integration methods, in combination with effective field theory. The classical amplitude involves polylogarithms with up to transcendental weight two and elliptic integrals. We derive the radial action directly from the amplitude, and determine the corresponding Hamiltonian in isotropic gauge. Our results are in agreement with known overlapping terms up to sixth post-Newtonian order, and with the probe limit. We also determine the post-Minkowskian energy loss from radiation emission at ${\cal O}(G^3)$ via its relation to the tail effect.

Nonsingular density profiles of dark matter halos and Strong gravitational lensing

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use the statistics of strong gravitational lenses to investigate whether mass profiles with a flat density core are supported. The probability for lensing by halos modeled by a nonsingular truncated isothermal sphere (NTIS) with image separations greater than a certain value (ranging from zero to ten arcseconds) is calculated. NTIS is an analytical model for the postcollapse equilibrium structure of virialized objects derived by Shapiro, Iliev & Raga. This profile has a soft core and matches quite well with the mass profiles of dark matter-dominated dwarf galaxies deduced from their observed rotation curves. It also agrees well with the NFW (Navarro-Frenk-White) profile at all radii outside of a few NTIS core radii. Unfortunately, comparing the results with those for singular lensing halos (NFW and SIS+NFW) and strong lensing observations, the probabilities for lensing by NTIS halos are far too low. As this result is valid for any other nonsingular density profiles (with a large core radius), we conclude that nonsingular density profiles (with a large core radius) for CDM halos are ruled out by statistics of strong gravitational lenses.

description: Lead borate (PB) and lead aluminoborate (PBA) glasses in the Systems xPbO · ( 1 0 0 - x)Β₂O₃ (0 ≤ x ≤ 75 mol%) and xPbO · (95 - x)Β₂O₃, 5AI₂O₃ (0 ≤ x ≤ 80 mol%), respectively, have been prepared and investigated by Raman and infrared reflectance spectroscopy to obtain quahtative and quantitative information on the structure of glasses. Using the Martin-Brenig model, structural correlation lengths were determinated from boson peak positions of temperature-reduced Raman spectra and transversal sound velocities. Kramers-Kronig analysis was used to transform the measured infrared reflectance spectra into complex dielectric funcdons. The imaginary part of the complex dielectric funcdon contains the absorption properties of t he material. Α band separadon Computer programme has been used to get more detailed information from the spectra. Far infrared and low-frequency Raman spectra contain information about vibrations of the PbO component within the network.

description: We report for the first time on triadic resonances in a rotating convection system. Using direct numerical simulations, we find that convective modes in a rotating spherical fluid can excite a pair of inertial modes whose frequencies and wavenumbers match the triadic resonance conditions. Depending on the structures of the convective modes, triadic resonances can lead to the growth of either a pair of modes with lower frequencies and wavenumbers, or a pair of modes with higher frequencies and wavenumbers, providing a possible mechanism for the bi-directional energy cascade. Increased thermal forcing leads to fully developed turbulence, which also exhibits wave-like motions, and is reminiscent of the energy spectrum of inertial wave turbulence. Our results suggest that the interaction of inertial waves plays an important role in rotating convection, which is of great importance in understanding the dynamics of planetary and stellar interiors.

description: The surface nucleation of high-quartz sohd Solution crystals at fractured surfaces of glasses of the stoichiometric cordierite composition (2MgO · 2AI₂O₃ · 5SiO₂) was studied by optical microscopy. Particular attention was focused on the nucleation kinetics. Α constant nucleation density, Ν ≈ 10⁻⁴ μm⁻², was found not to be significantly influenced by the time and the temperature of nucleation treatment. Even a very fast heating of samples employing heating rates u p to 1200 K/min does not lower Ν substantially. However, for small average crystal diameters ( < 2 0 μm) a distribution of crystal size in the same order of magnitude is detectable indicating a simultaneous appearance of b o t h measurable nucleation rates and growth velocities. It can be concluded that the surface nucleation of µ-cordierite occurs during the thermal treatment from a limited number of preferred nucleation sites; these sites are "used Up" rapidly enough to cause a strong Saturation effect of nucleation, but slow enough to cause a crystal size distribution at the same time. The surface nucleation rate, Is , was calculated from the observed distribution of crystal sizes. Is progressively increases with rising temperature similar to the crystal growth velocity indicating a broad temperature ränge of essential nucleation activity. The latter must be regarded as t he main obstacle to measure or to control surface nucleation density by means of two-step nucleation and growth treatments and must therefore be claimed to be mainly responsible for the observed constancy of N.

description: We investigate the radiative transport of dust in primordial galaxies in the presence of the UV radiation field from the first metal-free stars. We find that dust created in the first supernova (SN) explosions can be driven through the interior of the SN remnant to accumulate in the SN shells, where second-generation stars may form from compressed cooling gas. This scenario requires metal-free stars to form continuously over timescales of up to 10 Myr, consistent with recent estimates. Silicate and graphite grains, as well as iron-bearing magnetites, are transported to the shells for reasonable parameter assumptions, but their relative yields from primordial SNe is an important factor in the resulting abundance ratios. We compare the results of segregated grain transport with the current nucleosynthetic data on extremely metal-poor Galactic halo stars. Fossil signatures of this process may already have been detected in those iron-poor stars with enhanced carbon and silicate elements such as magnesium, silicon and oxygen. We discuss the implications of our results for the transition from first- to second-generation star formation in primordial galaxies, and the role played by the radiative transport of dust in this process.

description: Experimental control and detection of atoms and molecules often rely on optical transitions between different electronic states. In many cases, substructure such as hyperfine or spin-rotation structure leads to the need for multiple optical frequencies spaced by MHz to GHz. The task of creating multiple optical frequencies -- optical spectral engineering -- becomes challenging when the number of frequencies becomes large, a situation that one could encounter in complex molecules and atoms in large magnetic fields. In this work, we present a novel method to synthesize arbitrary optical spectra by modulating a monochromatic light field with a time-dependent phase generated through computer-generated holography techniques. Our method is compatible with non-linear optical processes such as sum frequency generation and second harmonic generation. Additional requirements that arise from the finite lifetimes of excited states can also be satisfied in our approach. As a proof-of-principle demonstration, we generate spectra suitable for cycling photons on the X-B transition in CaF, and verify via Optical Bloch Equation simulations that one can achieve high photon scattering rates, which are important for fluorescent detection and laser cooling. Our method could offer significant simplifications in future experiments that would otherwise be prohibitively complex.

description: We present temperature and field dependent heat capacity and magnetization data taken at temperatures down to 50 mK and in an applied magnetic field up to 11.5 Tesla for YbAgGe, a heavy-fermion compound with a field induced quantum critical point. These data clearly indicate that the same electronic degrees of freedom are responsible for the features seen in both specific heat and magnetization data. In addition, they further refine the different boundaries suggested for the H - T phase diagram of YbAgGe through previous, magneto-transport measurements, and allow for further understanding of different phases on the H - T phase diagram, in particular, clearly disconnecting the field-induced quantum critical point in YbAgGe from any sort of saturation of the Yb moment in higher applied magnetic field.

Semantic compression and pattern extraction with fascicles
Creators: name: Madar, Jason Chun-Sing
Publisher: name: University of British Columbia
Year: 2009

description: Often many records in a database share similar values for several attributes. If one is able to identify and group these records together that share similar values for some — even if not all — attributes, not only does one have the possibility of a more parsimonious representation of the data, but one may also gain useful insight into the data from an analysis and mining perspective. In this thesis, we introduce the notion of fascicles. A fascicle F(k,t) is a subset of records that have k compact attributes. An attribute A of a collection F of records is compact if the width of the range of A-values (for numeric attributes) or the number of distinct A-values (for categorical attributes) of all the records in F does not exceed t. We introduce and study two problems related to fascicles. First, we consider how to find fascicles such that the total storage of the relation is minimized. Second, we study how best to extract fascicles whose sizes exceed a given minimum threshold and that represent patterns of maximal quality, where quality is measured by the pair (k,t). We develop algorithms to attack both of the above problems. We show that these two problems are very hard to solve optimally. But we demonstrate empirically that good solutions can be obtained using our algorithms.

description: Against the background of the introduction of the new, low-alkaline compact dishwashing detergents and the associated glass damage during automatic dishwashing a comparative test was carried out. Glasses of different origin and composition were subjected to a continuous dishwashing test with up to 1000 cycles which compared the highly alkaline conventional detergent with different new formulation variants of low-alkaline compact detergents obtained from the market as well as with water. While the conventional and carbonate-containing compact detergent did not cause visible corrosion, the detergent with a high disilicate content already caused serious glass damage after 50 washing cycles in the form of clouding and iridescence. These phenomena render the drinking glasses esthetically unsuitable. At the same time, on-glaze decoration of chinaware which is n o t resistant to machine dishwashing is protected by these last-mentioned detergents. Details of the processes in the washed glass surface were examined by means of XPS depth profiles u p to a depth of 300 nm . It could be shown that during washing with automatic dishwashing detergents of a high disilicate content silica from the wash liquor separates in a similar structure as the glass itself on the glass surface, which causes the corrosion phenomena clouding and iridescence. Active substances and constituents of the wash liquor can be incorporated in the deposited layer. Since the new, low-alkaline compact detergents are gaining more and more importance on the market, this paper was intended to clarify the causes of increasing glass corrosion during machine dishwashing.

description: The charge and spin dynamics of the two-dimensional Hubbard model in the paramagnetic phase is first studied by means of the two-pole approximation within the framework of the Composite Operator Method. The fully self-consistent scheme requires: no decoupling, the fulfillment of both Pauli principle and hydrodynamics constraints, the simultaneous solution of fermionic and bosonic sectors and a very rich momentum dependence of the response functions. The temperature and momentum dependencies, as well as the dependency on the Coulomb repulsion strength and the filling, of the calculated charge and spin susceptibilities and correlation functions are in very good agreement with the numerical calculations present in the literature.
Transit cosmological models with observational constraints in f(Q, T) gravity

description: This cosmological model is a study of modified $f(Q,T)$ theory of gravity which was recently proposed by Xu {\it et al.} (Eur. Phys. J. C {\bf 79}, 708 (2019)). In this theory of gravity, the action contains an arbitrary function $f(Q,T)$ where $Q$ is non-metricity and $T$ is the trace of energy-momentum tensor for matter fluid. In our research, we have taken the function $f(Q,T)$ quadratic in $Q$ and linear in $T$ as $f(Q,T)=αQ+βQ^{2}+γT$ where $α$, $β$ and $γ$ are model parameters, motivated by $f(R,T)$ gravity. We have obtained the various cosmological parameters in Friedmann-Lemaitre-Robertson-walker (FLRW) Universe viz. Hubble parameter $H$, deceleration parameter $q$ etc. in terms of scale-factor as well as in terms of redshift $z$ by constraining energy-conservation law. For observational constraints on the model, we have obtained the best-fit values of model parameters using the available data sets like Hubble data sets $H(z)$, Joint Light Curve Analysis (JLA) data sets and union $2.1$ compilation of SNe Ia data sets by applying $R^{2}$-test formula. We have calculated the present values of various observational parameters viz. $H_{0}$, $q_{0}$, $t_{0}$ and statefinder parameters $(s,r)$, these values are very close to the standard cosmological models. Also, we have observed that the deceleration parameter $q(z)$ shows signature-flipping (transition) point within the range $0.423\leq z_{t}\leq0.668$ through which it changes its phase from decelerated to accelerated expanding universe with equation of state (EoS) $-1.071\leqω-0.96$ for $0\leq z\leq3$.

description: The theoretical energy requirement in meldng flat and Container glasses of the soda-lime-silica type from corresponding batches was directly measured at temperatures from 1370 to 1700 Κ using the drop-mixing method. In addition, the energy to be expended in headng the aforemendoned glasses, as well as calumite and ecomelt, from ambient temperature into the ränge from 1080 to 1700 Κ was determined using transposed-temperature drop calorimetry. Guided by the results, thermochemical methods proposed in the literature for the estimadon of the theoretical energy demand are critically assessed. Furthermore, the measured data are combined with information taken from thermochemical tables to derive the enthalpy effects contributing to the total enthalpy change associated with the conversion of the considered glass batches into the corresponding glass melts. On the basis of the information obtained, the ways in which the theoretical energy demand could be reduced are discussed. The influence of additions of cullet and other raw materials, such as calumite and spodumene, on the theoretical energy requirement is investigated, and the energy saving through additions of these materials is estimated.

description: Precision spectroscopy of atomic systems is an invaluable tool for the advancement of our understanding of fundamental interactions and symmetries. Recently, highly charged ions (HCI) have been proposed for sensitive tests of physics beyond the Standard Model and as candidates for high-accuracy atomic clocks. However, the implementation of these ideas has been hindered by the parts-per-million level spectroscopic accuracies achieved to date. Here, we cool a trapped HCI to the lowest reported temperatures, and introduce coherent laser spectroscopy on HCI with an eight orders of magnitude leap in precision. We probe the forbidden optical transition in $^{40}$Ar$^{13+}$ at 441 nm using quantum-logic spectroscopy and measure both its excited-state lifetime and $g$-factor. Our work ultimately unlocks the potential of HCI, a large, ubiquitous atomic class, for quantum information processing, novel frequency standards, and highly sensitive tests of fundamental physics, such as searching for dark matter candidates or violations of fundamental symmetries.

description: Spin-polarized transport through a band-gap-matched ZnSe/Zn_{1-x}Mn_{x} Se/ZnSe/Zn_{1-x}Mn_{x}Se/ZnSe multilayer structure is investigated. The resonant transport is shown to occur at different energies for different spins owing to the split of spin subbands in the paramagnetic layers. It is found that the polarization of current density can be reversed in a certain range of magnetic field, with the peak of polarization moving towards a stronger magnetic field for increasing the width of central ZnSe layer while shifting towards an opposite direction for increasing the width of paramagnetic layer. The reversal is limited in a small-size system. A strong suppression of the spin up component of the current density is present at high magnetic field. It is expected that such a reversal of the polarization could act as a possible mechanism for a selective spin filter device.

description: The range of non-Newtonian viscosity is usually connected with high strain rates or/and stresses. Therefore, the effect of heat dissipation (or viscous heating) cannot be neglected. In order to regard this effect various correlations were given in former papers, which will be analyzed and discussed in the present paper. It turns out that through the exact thermal elimination of viscous headng one can easily obtain the quantity of the pure, realistic and exclusively structurally determined non-Newtonian viscosity, ηnN, which may be normalized by the Newtonian viscosity, η0, to yield the form, ηnΝ/η0- At small amounts of strain and stress other expressions, such as η/η0,Tmax and η/η0,Tnet, may describe the non-Newtonian flow behaviour approximately where the thermal elimination is not made for the as-measured non-Newtonian viscosity, η, but for the Newtonian values, ηο. (η0,Tmax Stands for the adiabatically corrected Newtonian viscosity, due to the maximum temperature of viscous heating by the total deformation work; η0,Tnet Stands for t h e nonadiabadcally corrected Newtonian viscosity due to the gross temperature of viscous heating, regarding also the heat flow out of t he glass sample.) In contrast to these more or less pure non-Newtonian normalized viscosities the so-called normalized non-Newtonian gross viscisity, η/η0, is that viscosity which involves the viscosity decrease due to the pure non-Newtonian flow, determined by structural orientation, as well as the viscosity decrease due to the viscous heating. The various relationschips are analyzed and discussed with the help of recently developed rheological equations.

description: The objectives of this report were to investigate 1) the potential benefits of using flexible posts for post delineators and 2) the possibility of not requiring post delineators on sections of interstate-type highways where recessed markers are installed.  It is recommended that post delineators should only be used when the design curvature is 1.5 degrees or more, and the spacing should be based on the formula given in Table III – 1 of the MUTCD. Data obtained concerning the performance of flexible posts do not support widespread use at this time. A testing program should be developed to obtain an approved list of flexible posts and, after an evaluation period, expanded use of flexible posts might be recommended. Steel posts used as delineator posts should be lightweight (1.1 pounds per foot).

description: The objective of the study was to evaluate the cost-effectiveness of available marking materials by means of field tests and to make recommendations concerning the optimum lane delineation materials based on these tests. Materials tested include 100-percent solid epoxy paint, polyester paint, extruded thermoplastic, 3M Stamark tape, 3M Bisymmetric tape, EPOFLEX, solvent epoxy paint, chlorinated rubber traffic paint, and alkyd traffic paint. The test installations have been in place up to four years. The evaluation concerned the durability, reflectivity, and appearance of the materials. Based on current data, expanded use is warranted for 1) polyester paint on lower-volume asphaltic concrete surfaces, 2) extruded thermoplastic on higher-volume asphaltic concrete highways with lighting or snowplowable markers, and 3) extruded thermoplastic on open-graded asphaltic surfaces.

description: Deep learning has been widely and actively used in various research areas. Recently, in the gauge/gravity duality, a new deep learning technique so-called the AdS/Deep-Learning (DL) has been proposed [1, 2]. The goal of this paper is to describe the essence of the AdS/DL in the simplest possible setups, for those who want to apply it to the subject of emergent spacetime as a neural network. For prototypical examples, we choose simple classical mechanics problems. This method is a little different from standard deep learning techniques in the sense that not only do we have the right final answers but also obtain a physical understanding of learning parameters.

description: Leakage currents and their low resistance paths through refractories from the interior of glass melting furnaces to the binding steel are discussed. By defmition, a ground current flows from an electrode, through the intervening glass to ground through grounding conductors. All melters have leakage currents and may have ground currents. Current and voltage characteristics and phasor diagrams have been analyzed for some circuits that can be used in horizontal melters. The furnaces may be heated solely with electricity or in conjuncdon with fossil fuels. Phasor diagrams may be helpful in the design stage of a melter, may be useful for trouble-shoodng and to display electrical distributions for all parts in a precise form. Hence, totally unexpected voltage differences become easily understandable. Phasor diagrams can disclose wiring errors and/or undesirable voltage distributions and may suggest ways to improve electrical characteristics. For symmetrically built and cross-fired furnaces they show side-to-side symmetry and indicate that the central plane of these units can be Virtual or phantom grounds. They may also indicate the conditions minimizing voltage differences between adjacent electrodes. Voltage phasor diagrams are even more useful for longitudinally fired furnaces. For these units they also explain why ground currents occur and how to minimize them. Data from a salt water model with two cross-fired circuits connected to the same phase disclosed linear relations between the electric currents and voltages over a large range. In this ränge each line current was a hnear function of the two line voltages and vice versa and these variables could be treated as scalars. In addition, either line current could be forced to zero by appropriate voltage(s) in the other circuit. Somewhat similar results were obtained when two different phases were used but now neither current could be forced to zero by adjusting the voltage in the other circuit. Again in the linear range each hne current was a linear function of the line voltages and vice versa but the variables now had to be treated as phasors and not as scalar quantities. Salt water modelling with a longitudinally fired melt end yielded representative data showing how the applied voltages may be located on a ground current's voltage phasor in both the capped and uncapped condition.

description: The first large-scale contracts for the installation of snowplowable markers were awarded in 1984 and 1985. Stimsonite 96 and recessed markers were installed. The objective of this study was to evaluate the performance of the installations. Durability and reflectivity results show that both the recessed markers and Stimsonite 96 markers have performed effectively as snowplowable markers. The recessed markers should continue to be used only on four-lane highways constructed to high geometric standards with the Stimsonite 96 markers installed on the majority of highways.

description: Glass melts of various homologous Silicate glass series were investigated by means of the cylinder compression method with respect to their flow behaviour (Newtonian and non-Newtonian), stress generadon modulus (stiffness, brittleness) and critical deformadon rate (high-temperature tensile strength, isochomal workability). The experimental results show that decreasing CaO content and increasing basicity lead to the decrease of the brittleness of Silicate glass melts and to the increase of the critical deformadon rate, i.e. to the improvement of the isochomal workability of these melts. The mixed alkali effect of sodium potassium calcium Silicate glass melts at molar fracdon [K₂O]/[Na₂O+K₂O] = 0.5 has a favourable influence on the isochomal workability The correladon between flow behaviour and workability of glass melts is also discussed in the present paper. It could be shown that the ratio β = E2.8/E3.6 (E is the extinction of the hydroxyl band at 2.8 and 3.6 ηm, respectively) indicates the structural origin of the dependence of the mentioned rheological properties on the chemical compositions, at least within the homologous series.

description: Sections of the new Alexandria-Ashland (M) highway in northeastern Kentucky must be located on and through natural slopes of the Kope and Crab Orchard Formations that consist mainly of shales. Numerous highway embankment and cut slope failures have occurred In these two geologic formations In past years. The shales of these formations have very poor and undesirable engineering properties. Many stability problems encountered with the Kope and Crab Orchard shales are caused primarily by the tendency of those shales to breakdown when exposed to water and produce clays and clayey silts of relatively low shear strengths. Construction of highway embankments with, through, and on the shales of the Kope and Crab Orchard Formations has been necessary because of the vast aerial presence of these shales and the Jack of more suitable and economical alternate construction materials. In the design of the AA highway, geotechnical engineers were faced with three difficult problems. First, In forming embankments, there was a question of how the shales should be compacted and what constituted proper compaction. Second, the most difficult problem, perhaps, was the selection of appropriate shear strength parameters of the overconsolidated clays and clayey shales of the natural slope foundations and the embankments constructed of the shales. Numerous landslide studies Involving overconsolidated clays and clay shales show that use of peak strengths from triaxial tests may lead to underconservative designs while use of residual shear strengths may lead to uneconomical designs. A third factor complicating the design of shale embankments on weathered shale slopes Is the seepage of water Into the embankment. Exposure of the lower portions of the embankments composed of Kope and Crab Orchard shales to seepage and rapid-drawdown conditions created by the Ohio River make the shales susceptible to breakdown and swelling and may produce a progressive "softening• and decrease In shear strengths. The design of certain sections of the AA highway passing through the Kope and Crab Orchard shales was further complicated by the fact that some natural slopes and existing highway fills having slopes of 3 horizontal to 1 vertical are failing. The design problem became one of placing new highway embankments on existing failing natural slopes. This paper presents case histories to document existing failures and discusses the treatment of the three factors -- compaction, shear strength, and seepage. A discussion of the different aspects of the geotechnical design for new fill placement is presented. Emphasis is placed on the selection and justification of design parameters for foundation and embankment materials as well as the construction procedures and compaction specification that were finally adopted.

description: Questo saggio si propone di riconsiderare le  idee di Lukács sul romanzo, collocate nell’ambito di una complessa riflessione che prende le mosse dalla  condizione tragica dell’uomo nella modernità. La teoria del romanzo di  Lukács si  sviluppa in due  momenti  molto diversi del Novecento: a inizio secolo, con Teoria del romanzo, e negli anni Trenta e Quaranta, con i saggi sul realismo. I due Lukács tuttavia si incontrano mirabilmente in una pagina del saggio sul Significato attuale del realismo critico. Solo in apparenza desueto, tutto il pensiero estetico di Lukács ci invita dunque a ripensare qui e ora il problema, latamente politico, della relazione del testo con il mondo.

description: We describe the internal composition of a topologically stable monopole carrying a magnetic charge of $6π/e$ that arises from the spontaneous breaking of the trinification symmetry $SU(3)_c\times SU(3)_L\times SU(3)_R$ ($G$). Since this monopole carries no color magnetic charge, a charge of $6π/e$ is required by the Dirac quantization condition. The breaking of $G$ to the Standard Model occurs in a number of steps and yields the desired topologically stable monopole ("magnetic baryon"), consisting of three confined monopoles. The confined monopoles ("magnetic quarks") each carry a combination of Coulomb magnetic flux and magnetic flux tubes, and therefore they do not exist as isolated states. We also display a more elaborate configuration ("fang necklace") composed of these magnetic quarks. In contrast to the $SU(5)$ monopole which is superheavy and carries a magnetic charge of $2π/e$ as well as color magnetic charge, the trinification monopole may have mass in the TeV range, in which case it may be accessible at the LHC and its planned upgrades.

Stucturall characterization of concentrated alkaline Silicate Solutions by ²⁹Si-NMR spectroscopy, FT-IR spectroscopy, lightscattering, and electronmicroscopy - molecules, colloids, and dissolution artefacts

description: Sodium and potassium Silicate soludons (water glass; molar rados SiO₂: Na₂O = 2.0 and 3.3, SiO₂ content = 25 wt%; molar rados SiO₂: K₂O = 3.3 a n d 4.0, SiO₂ content = 25 a n d 20 wt%, respectively) were prepared and characterized, e.g. by ²⁹Si-NMR spectroscopy, F T - IR spectroscopy, Raman spectroscopy, or dynamic light scattering. One type of sodium Silicate Solution (molar ratio SiO₂: Na₂O = 2.0) was prepared by three different methods from different precursors (two glasses with different chemical compositions and quartz). The structure of these concentrated alkaline Silicate soludons is determined by the "molecular" and the "colloidal" fraction of silica. For the investigation of the molecular Silicate components the ²⁹Si-NMR spectroscopy and the FT-IR spectroscopy yielded the most valuable results. Dynamic light scattering allowed to detect minute amounts of artefacts (possibly remnants of the dissolving species) of the production process with diameters > 100 nm. By filtering off these artefacts it was possible to characterize the colloidal fracdon of the sodium Silicate soludons. Monomodal particle size distribudons with maxima at 30 to 35 nm were found. The Solutions with the higher sodium contents have the smaller particles. Electron microscopy supported the light scattering results concerning the particle sizes and gave an Impression that the major part of silica is present in colloidal form. The preparation method had almost no influence on the molecular structure of the alkaline Silicate Solutions. This and the monomodal size distributions of the colloids can be interpreted by the assumption of a (metastable) equilibrium State.
