description: Let $X=\{X(t), t\geq 0\}$ be a Brownian motion or a spectrally negative stable process of index $10$. This establishes the lower bound in the law of the iterated logarithm which we could not prove with the techniques of our paper \cite{MNX}. We also obtain exact small ball probability for $X(E_t)$ using ideas from \cite{aurzada}.

description: We study two ions confined in a Penning trap. We show that electronically highly excited states exist in which an electron is delocalized among the two ions forming a giant molecule of several micrometer size. At energies close to the top of the Coulomb barrier these molecular states can be regarded as superpositions of Rydberg states of individual ions. We illuminate the possibility to observe coherent charge transfer between the ions. Beyond a critical principal quantum number the electron can coherently tunnel through the Coulomb barrier to an adjacent doubly charged ion. The tunneling occurs on timescales on which the dynamics of the nuclei can be considered frozen and radiative decay can be neglected.

description: We use a combination of new AAOmega multi-object wide-field spectroscopic observations and literature data to define 111 spectroscopically confirmed members of the massive NGC 5044 group with M_B <= -13.5 mag, providing a three-fold increase in group members over previous analyses of this group. We find the group to have a dynamical mass of 9.2 x 10^13 solar masses, placing it on the border between rich groups and poor clusters. However, comparison to the L_x-sigma and L_x-mass relations shows it more closely follows cluster scaling relations. Using a combination of crossing time, X-ray contours and line-of-sight velocity profile we are able to preclude growth of the NGC 5044 group via major sub-group mergers within the last ~1 Gyr. While the majority of dynamical indicators for the group suggest it is virialised, we find evidence for a small, dynamically distinct sub-group at 1.4 Mpc from the group centre, suggesting that the NGC 5044 group is the dominant structure in its local environment, and is currently accreting smaller groups.

description: Using an external electric field, one can modulate the bandgap of Bernal stacked bilayer graphene by breaking A-~B symmetry. We analyze strain effects on the bilayer graphene using the extended Huckel theory and find that reduced interlayer distance results in higher bandgap modulation, as expected. Furthermore, above about 2.5 angstrom interlayer distance, the bandgap is direct, follows a convex relation to electric field and saturates to a value determined by the interlayer distance. However, below about 2.5 angstrom, the bandgap is indirect, the trend becomes concave and a threshold electric field is observed, which also depends on the stacking distance.

Hypotrix optima

description: Hypotrix optima (Dyar, [1920]), comb. n. Figs 14, 29, 44 Scriptania optima Dyar, [1920]: 163. Type material. Holotype ♁ [USNM, examined]. Type locality: Mexico, Mexico City. Other material examined and distribution. Mexico: Federal District, State of Durango (Sierra Madre Occidental). USA: Arizona: Cochise Co. (Chiricahua Mts). Diagnosis. Hypotrix optima is a small Hypotrix (forewing length 11–14 mm) with an unmistakable forewing pattern. Th e mainly orange and gray pattern is dominated by the pale yellow shading around the orbicular spot that forms a flat-bottomed wedge mark between the dark gray reniform and orbicular spots, and the yellow streak at the forewing apex. Dark-gray shading in the basal area, on the reniform and orbicular spots, and in the subterminal area gives the forewing a distinctive blotchy look. Th e hindwing is translucent white in both sexes. The male genitalia are most similar to those of H. trifascia, but the valves are more slender and the apical half of the uncus is broad and spatulate. Th e vesica is about 2 × as long as the aedeagus with a tight cluster of cornuti at the base, several scattered spikelike cornuti subbasally, and a cluster of minute spines subapically after a postmedial coil. The female genitalia are similar to those of H. trifascia but the corpus bursae is curved rather than oval, and the ductus bursae is heavily sclerotized with long medial bulges on both sides. Distribution and biology. Hypotrix optima occurs from southeastern Arizona and central New Mexico southward to Mexico City. Collecting dates range from mid-June to mid-July.

description: We discuss some cosmological implications of extensions of the Standard Model with hidden sector scalars coupled to the Higgs boson. We put special emphasis on the conformal case, in which the electroweak symmetry is broken radiatively with a Higgs mass above the experimental limit. Our refined analysis of the electroweak phase transition in this kind of models strengthens the prediction of a strongly first-order phase transition as required by electroweak baryogenesis. We further study gravitational wave production and the possibility of low-scale inflation as well as a viable dark matter candidate.

description: To evaluate the antibacterial and antibiofilm activities of sodium ibuprofenate (NaI) and its hypertonic variant (NaIHS) against multidrug-resistant Gram-negative bacteria (MDR-GNB) and explore their potential to inhibit β-lactamase enzymes. Antibacterial activity was assessed using minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and time-kill assays. Antibiofilm activity was evaluated by measuring bacterial viability and biomass reduction in preformed biofilms. Scanning electron microscopy (SEM) was used to observe membrane effects. Molecular docking and molecular dynamics simulations were conducted to analyze the binding affinity of ibuprofen to the active sites of β-lactamases (CTX-M-15, KPC-2, OXA-23). NaI exhibited bactericidal activity at concentrations of 25–75 mm, with Acinetobacter baumannii being the most susceptible. NaCl (≥0.5 M) enhanced bactericidal efficacy and lowered MBCs. Time-kill assays indicated rapid bacterial eradication within 2 hours, with NaIHS achieving similar results at lower concentrations. SEM confirmed membrane disruption. Both formulations reduced bacterial viability in biofilms, with NaIHS showing greater efficiency. In silico studies suggest ibuprofen may inhibit β-lactamases, with enhanced interactions in saline environments. Sodium ibuprofenate, particularly in its hypertonic form, demonstrates strong antibacterial, antibiofilm, and potential β-lactamase inhibitory activity, making it a promising candidate for treating MDR-GNB infections. Some bacteria, called “superbugs,” are very hard to treat because they resist most antibiotics. These superbugs can cause serious infections, so it’s important to find new ways to fight them. In this study, we tested a special type of ibuprofen, called sodium ibuprofenate, to see if it could help fight superbugs. We also looked at whether it could affect two ways these bacteria protect themselves: biofilms, where they form a protective layer, and enzymes that make them resistant to antibiotics. We found that sodium ibuprofenate, especially when mixed with salt, can kill bacteria both in biofilms and on their own. It also weakens the biofilms and may help antibiotics work better. These results are important because this combination could be a new way to treat infections caused by resistant bacteria, but more research is needed.

description: This study aims to investigate how different wound microenvironmental factors (temperature, pH, and osmotic pressure) influence the autofluorescence of Staphylococcus aureus (S. aureus) and its underlying molecular mechanisms, specifically focusing on the porphobilinogen synthase gene (hemB) gene expression. We measured the average fluorescence intensity of S. aureus colonies under varying conditions of pH (3, 5, 7, 9, 11), temperature (25°C, 31°C, 37°C, 43°C), and osmotic pressure (0.9%, 1.8%, 2.7%, 3.6%) over time. Fluorescence intensity was quantified using ImageJ software. Additionally, RT-qPCR was used to analyze the expression levels of the hemB under these conditions. Bacterial fluorescence intensity increased as the temperature ranged from 25°C to 43°C, with corresponding upregulation of hemB expression. At pH values between 3 and 11, fluorescence intensity decreased as pH increased, reflecting a similar trend in hemB expression. Fluorescence also diminished with higher osmotic pressures (0.9% to 3.6%), mirroring the downregulation of hemB. Our findings indicate that temperature, pH, and osmotic pressure significantly affect the autofluorescence of S. aureus by modulating porphyrin accumulation through hemB gene expression. These environmental factors should be considered when using bacterial fluorescence for wound infection assessment. There are many bacteria on our skin that can behave differently when we get a cut in the skin. One way that doctors look at how the bacteria are behaving in a cut is using fluorescence, where the bacteria glow in the dark. This research looks at how whether changes in temperature, acidity and salt can change the way that bacteria glow in the dark. We found that when it was warmer, the bacteria glow more brightly. This brightness is linked to a gene called hemB in the bacteria. On the other hand, if the environment becomes less acidic or if there is a lot of salt, the bacteria do not glow as brightly. By watching these changes in fluorescence, doctors can get a better idea of what’s happening with the bacteria in the wound. Our research shows that when using this bacterial fluorescence to check on wounds, we need to remember the effects of environmental factors.
Deformed matrix models, supersymmetric lattice twists and N=1/4 supersymmetry

description: A manifestly supersymmetric nonperturbative matrix regularization for a twisted version of N=(8,8) theory on a curved background (a two-sphere) is constructed. Both continuum and the matrix regularization respect four exact scalar supersymmetries under a twisted version of the supersymmetry algebra. We then discuss a succinct Q=1 deformed matrix model regularization of N=4 SYM in d=4, which is equivalent to a non-commutative $A_4^*$ orbifold lattice formulation. Motivated by recent progress in supersymmetric lattices, we also propose a N=1/4 supersymmetry preserving deformation of N=4 SYM theory on $\R^4$. In this class of N=1/4 theories, both the regularized and continuum theory respect the same set of (scalar) supersymmetry. By using the equivalence of the deformed matrix models with the lattice formulations, we give a very simple physical argument on why the exact lattice supersymmetry must be a subset of scalar subalgebra. This argument disagrees with the recent claims of the link approach, for which we give a new interpretation.

Other material examined and distribution. USA: Arizona. Cochise Co. (Chiricahua and Huachuca Mts), Graham Co. (Pinaleno Mts), and Santa Cruz Co. (Santa Rita Mts). Diagnosis. Hypotrix hueco is superficially similar to H. alamosa, but averages larger (forewing length: 14–16 mm), the medial area is pale with whitish shading that contrasts with the darker color of the basal and subterminal areas, and the postmedial line is well removed from the outer edge of the reniform spot. Th e outward displacement of the postmedial line results in a very narrow subterminal area, similar in width to the terminal area. Surprisingly, the male genitalia are most similar to those of H. lunata, with a high dorsal tuft of setae on the broadly spatulate uncus and the cucullus is long and tapered with a folded depressed area at the base of the dorsal margin. Th e vesica is about 3 × as long as the aedeagus; there are two spiny clusters where the aedeagus joins the vesica, a row of three long spike like cornuti near the vesica base, and a premedial coil. The female genitalia are similar to those of H. lunata, but the appendix bursae has only one coil. Distribution and biology. Hypotrix hueco is known only from southeastern Arizona. Collecting dates range from mid-June to mid-August.

description: There is a unique Lorentz-violating modification of the Maxwell theory of photons, which maintains gauge invariance, CPT, and renormalizability. Restricting the modified-Maxwell theory to the isotropic sector and adding a standard spin-one-half Dirac particle p^\pm with minimal coupling to the nonstandard photon \widetildeγ, the resulting modified-quantum-electrodynamics model involves a single dimensionless "deformation parameter," \widetildeκ_{tr}. The exact tree-level decay rates for two processes have been calculated: vacuum Cherenkov radiation p^\pm \to p^\pm \widetildeγ for the case of positive \widetildeκ_{tr} and photon decay \widetildeγ \to p^+ p^- for the case of negative \widetildeκ_{tr}. From the inferred absence of these decays for a particular high-quality ultrahigh-energy-cosmic-ray event detected at the Pierre Auger Observatory and an excess of TeV gamma-ray events observed by the High Energy Stereoscopic System telescopes, a two-sided bound on \widetildeκ_{tr} is obtained, which improves by eight orders of magnitude upon the best direct laboratory bound. The implications of this result are briefly discussed.

description: Classical black holes shield us from the singularities that inevitably appear in general relativity. Being singularity regularization one of the main landmarks for a successful theory of quantum gravity, quantum black holes are not obliged to hide their inner core from the outside world. Notwithstanding the aforesaid, it is often implicitly assumed that quantum gravity effects must remain confined to black hole interiors. In this essay we argue in the opposite direction, discussing theoretical evidence for the existence of strong correlations between the physics inside and outside non-singular black holes. We conclude that astronomical tests of the surroundings of black holes can provide invaluable information about their so-far unexplored interiors.

description: We examine the one-dimensional Gross-Pitaevskii lattice at zero temperature in the presence of uncorrelated disorder. We obtain analytical expressions for the thermodynamic properties of the ground state field and compare them with numerical simulations both in the weak and strong interaction regimes. We analyze weak excitations above the ground state and compute the localization properties of Bogoliubov-de Gennes modes. In the long-wavelength limit, these modes delocalize in accordance with the extended nature of the ground state. For strong interactions, we observe and derive a divergence of their localization length at finite energy due to an effective correlated disorder induced by the weak ground state field fluctuations. We derive effective strong interaction field equations for the excitations and generalize to higher dimensions.
The poetry of Ts'ao Chih : a critical introduction
Creators: name: Russell, Terence Craig
Publisher: name: University of British Columbia
Year: 2010

description: The form which this thesis has taken is rather different from what I had originally envisioned. It contains far more discussion of literary style and far less translation than I had planned to include. This is both a virtue.- and a shortcoming. Certainly it has been much more. Interesting to have attempted an analysis of some of the literary forces which molded and characterized the poetry of Ts'ao Chih and the Chien An writers than it would have been simply to have translated a large number of their works. I have made many fascinating discoveries and the reader will surely find more substance to occupy his attention. However, it is difficult to avoid feeling that to try to analyse and criticise poetry which one has the greatest difficulty even reading, and which is the product of a literary tradition as remote as that of third century China, is very presumptuous. After all, if as accomplished and mature a scholar as Professor Donald Holzman would decline to engage in just this type of discussion on the grounds that he felt it so difficult as to 'actually defeat its own purpose' how could I hope for any kind of success? Nevertheless, as mentioned, I have learned much through the preparation of this work and generally don't regret my presumption. It is perhaps only necessary to forewarn the reader that many of the statements made herein are of a tentative and speculative nature and are not in any respect the last word on the subject. Yet if these speculations lead the reader to a slightly deeper appreciation of certain facets of the fine poetry of Ts'ao Chih, or even if they only stimulate him to seek such appreciation on his own, then I will consider that my work has not been completely in vain. I have placed my translations of Ts'ao Chih's poems at the end of the thesis. This is only because, that seemed to be the only logical place to put them. It does not indicate that I consider them to form merely a kind of appendix which the reader may refer to for his own convenience. On the contrary, I have spent a great deal of time in preparing these translations and would like to think that they are a significant improvement over those previously available. Thus they represent perhaps, an even greater 'contribution to knowledge' than does the main body of my text. In my translations I have followed Huang Chieh's text except where otherwise indicated. Wherever possible I have recorded variant wordings but, due to a lack of library resources and personal interest, I have not attempted to indulge in extensive textual commentary. I have striven to present translations that are both accurate and fulfil the axiom that a translation must be good poetry in its own right in order to be successful. I have used the modified Wade-Giles system of romanization found in the Mathews' Chinese English Dictionary throughout. To this system I have made a few minor modifications of my own but these should be quite self-evident.

description: The affine Dynkin diagram of type $A_n^{(1)}$ has a cyclic symmetry. The analogue of this Dynkin diagram automorphism on the level of crystals is called a promotion operator. In this paper we show that the only irreducible type $A_n$ crystals which admit a promotion operator are the highest weight crystals indexed by rectangles. In addition we prove that on the tensor product of two type $A_n$ crystals labeled by rectangles, there is a single connected promotion operator. We conjecture this to be true for an arbitrary number of tensor factors. Our results are in agreement with Kashiwara's conjecture that all `good' affine crystals are tensor products of Kirillov-Reshetikhin crystals.

description: As one of the fitting methods, the polynomial approximation is effective to process sophisticated problem. In this paper, we employ this approach to handle the scattering of scalar field around the Schwarzschild-de Sitter black-hole. The complex relationship between tortoise coordinate and radial coordinate is replaced by the approximate polynomial. The Schr$\ddot{o}$dinger-like equation, the real boundary conditions and the polynomial approximation construct a full Sturm-Liouville type problem. Then this boundary value problem can be solved numerically according to two limiting cases: the first one is the Nariai black-hole whose horizons are close to each other, the second one is when the horizons are widely separated. Compared with previous results (Brevik and Tian), the field near the event horizon and cosmological horizon can have a better description.

description: We show that the isotropic lines in the lattice Z_{d}^{2} are the Lagrangian submodules of that lattice and we give their number together with the number of them through a given point of the lattice. The set of isotropic lines decompose into orbits under the action of SL(2,Z_d). We give an explicit description of those orbits as well as their number and their respective cardinalities. We also develop two group actions on the group Σ_{D}(M) related to the topic.

description: Let f : X --> Y be a holomorphic map of complex manifolds, which is proper, Kahler, and surjective with connected fibers, and which is smooth over Y-Z the complement of an analytic subset Z. Let E be a Nakano semi-positive vector bundle on X, and consider direct image sheaves F = R^qf_*(K_{X/Y} \otimes E) for q \geq 0. In our previous paper, we discussed the Nakano semi-positivity of F with respect to the so-called Hodge metric, when the map f is smooth. In this paper, we discuss the extension of the induced metric on the tautological line bundle O(1) on the projective space bundle P(F) ``over Y-Z'' as a singular Hermitian metric with semi-positive curvature ``over Y''. As a particular consequence, if Y is projective, R^qf_*(K_{X/Y} \otimes E) is weakly positive over Y-Z in the sense of Viehweg.

description: Heat capacity measurements were performed on recently discovered iron based layered superconductors, non doped LaFePO and fluorine doped LaFePO. A relatively large electronic heat capacity coefficient and a small normalized heat capacity jump at Tc = 3.3 K were observed in LaFePO. LaFePO0.94F0.06 had a smaller electronic heat capacity coefficient and a larger normalized heat capacity jump at Tc = 5.8 K. These values indicate that these compounds have strong electron electron correlation and magnetic spin fluctuation, which are the signatures of unconventional superconductivity mediated by spin fluctuation.

Understanding the problem of glass transition on the basis of elastic waves in a liquid

description: We propose that the properties of glass transition can be understood on the basis of elastic waves. Elastic waves originating from atomic jumps in a liquid propagate local expansion due to the anharmonicity of interatomic potential. This creates dynamic compressive stress, which increases the activation barrier for other events in a liquid. The non-trivial point is that the range of propagation of high-frequency elastic waves, $d_{\rm el}$, increases with liquid relaxation time $τ$. A self-consistent calculation shows that this increase gives the Vogel-Fulcher-Tammann (VFT) law. In the proposed theory, we discuss the origin of two dynamic crossovers in a liquid: 1) the crossover from exponential to non-exponential and from Arrhenius to VFT relaxation at high temperature and 2) the crossover from the VFT to a more Arrhenius-like relaxation at low temperature. The corresponding values of $τ$ at the two crossovers are in quantitative parameter-free agreement with experiments. The origin of the second crossover allows us to reconcile the ongoing controversy surrounding the possible divergence of $τ$. The crossover to Arrhenius relaxation universally takes place when $d_{\rm el}$ reaches system size, thus avoiding divergence and associated theoretical complications such as identifying the nature of the phase transition and the second phase itself. Finally, we discuss the effect of volume on $τ$ and the origin of liquid fragility.

Possible contributions to $e^+e^- \to J/ψ+ η_c$ due to intermediate meson rescatterings

description: Inspired by the obvious discrepancies between experiment and non-relativistic QCD (NRQCD) studies of $e^+ e^-\to J/ψ+η_c$ at $\sqrt{s}\simeq 10.6$ GeV, we investigate contributions from intermediate meson loops as long-range interaction transitions to this process. The intermediate meson loops include $D\bar D(\bar D^\ast)$, $D\bar D^\ast(D {or} D^\ast)$, $D^\ast \bar D^\ast(D)$ and corresponding $D_s$ intermediate mesons. With the constraints from experimental data on the vertex couplings, we find that the intermediate meson loops account for $2.7\sim 6.7 fb$ of the cross sections within a reasonable range of cut-off energies of the factor parameter. We also investigate contributions from the absorptive part and find that it accounts for approximately $0.58\sim 1.38 fb$. These results imply that contributions from long-range interaction transitions may still play a role in such an energy region.

Chiral Selection, Isotopic Abundance Shifts, and Autocatalysis of Meteoritic Amino Acids

description: The discovery of amino acids in meteorites has presented two clues to the origin of their processing subsequent to their formation: a slight preference for left-handedness in some of them, and isotopic anomalies in some of their constituent atoms. In this article we present theoretical results from the Supernova Neutrino Amino Acid Processing (SNAAP) model, which uses electron anti-neutrinos and the magnetic fields from source objects such as supernovae or colliding neutron stars to selectively destroy one amino acid chirality and to create isotopic abundance shifts. For plausible magnetic fields and electron anti-neutrino fluxes, non-zero, positive enantiomeric excesses, $ee$s, defined to be the relative left/right asymmetry in an amino acid population, are reviewed for two amino acids, and conditions are suggested that would produce $ee>0$ for all of the $α$-amino acids. The relatively high energy anti-neutrinos that produce the $ee$s would inevitably also produce isotopic anomalies. A nuclear reaction network was developed to describe the reactions resulting from them and the nuclides in the meteorites. At similar anti-neutrino fluxes, assumed recombination of the detritus from the anti-neutrino interactions is shown to produce appreciable isotopic anomalies in qualitative agreement with those observed for D/$^1$H and $^{15}$N/$^{14}$N. The isotopic anomalies for $^{13}$C/$^{12}$C are predicted to be small, as are also observed. Autocatalysis may be necessary for any model to produce the largest $ee$s observed in meteorites. This allows the constraints of the original SNAAP model to be relaxed, increasing the probability of meteoroid survival in sites where amino acid processing is possible. These results have obvious implications for the origin of life on Earth.

description: We analyse a light charged Higgs boson in the 2-Higgs Doublet Model (2HDM) Type-I, when its mass satisfies the condition $M_{H^{\pm}} < M_{t}+M_{b}$ and the parameter space is consistent with theoretical requirements of self-consistency as well as the latest experimental constraints from Large Hadron Collider (LHC) and other data. Over such a parameter space, wherein the Standard Model (SM)-like state discovered at the LHC in 2012 is the heaviest CP-even state of the 2HDM, it is found that the decay modes of the charged Higgs boson are dominated by $H^{\pm} \rightarrow W^{\pm *} h$. Furthermore, the light neutral Higgs boson $h$ dominantly decays into two photons. Under these conditions, we find that the production and decay process $ p p \to H^\pm h \to {W^\pm}^{(*)} h h \to l ν_{l} + 4 γ$ ($l=e,μ$) is essentially background free. However, since the $W^{\pm(*)}$ could be largely off-shell and the $h$ state is very light, so that both the lepton coming from the former and the photons coming from the latter could be rather soft, we perform here a full Monte Carlo (MC) analysis at the detector level demonstrating that such a $W^{\pm} + 4γ$ signal is very promising, as it would be yielding significant excesses at the LHC with an integrated luminosity of $L=$ 300 $fb^{-1}$ at both $\sqrt{s}= 13$ and $14 ~\text{TeV}$.
