description: In this work, we revisit a criterion, originally proposed in [Nonlinearity {\bf 17}, 207 (2004)], for the stability of solitary traveling waves in Hamiltonian, infinite-dimensional lattice dynamical systems. We discuss the implications of this criterion from the point of view of stability theory, both at the level of the spectral analysis of the advance-delay differential equations in the co-traveling frame, as well as at that of the Floquet problem arising when considering the traveling wave as a periodic orbit modulo a shift. We establish the correspondence of these perspectives for the pertinent eigenvalue and Floquet multiplier and provide explicit expressions for their dependence on the velocity of the traveling wave in the vicinity of the critical point. Numerical results are used to corroborate the relevant predictions in two different models, where the stability may change twice. Some extensions, generalizations and future directions of this investigation are also discussed.

A Note on D1-D5-J System and 5D Small Black Ring

description: The ``small'' black ring in 5D obtained by giving angular momentum to the D1-D5 system compactified on S^1 x K3 is a very interesting object in the sense that it does not have an event horizon in the supergravity limit whereas it microscopically has a finite entropy. The microscopic origin of this small black ring can be analyzed in detail since it is constructed by adding angular momentum to the well-studied D1-D5 system. On the other hand, its macroscopic, geometrical picture is difficult to study directly. In this note, by duality transformations and the 4D-5D connection, we relate this 5D small black ring to a 4D small non-rotating black hole, where the latter is known to develop a non-vanishing horizon due to stringy R^2 corrections to the supergravity action. This gives an indirect evidence that a non-vanishing horizon is formed for the 5D small black ring. We also show that the entropy of the 4D small black hole agrees with the microscopic entropy of the 5D small black ring, which supports that the 4D-5D connection is indeed valid even for small black objects.

The inclusive transverse response of nuclear matter

Publisher: name: arXiv
Year: 1996
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The electromagnetic inclusive transverse response of nuclear matter at saturation density is studied within the correlated basis function perturbation theory for momentum transfers q from 300 to 550 MeV/c. The correlation operator includes a Jastrow component, accounting for the short range repulsion, as well as longer range spin, tensor and isospin ones. The Schiavilla- Pandharipande-Riska model for the two-body electromagnetic currents, satisfying the continuity equation with realistic v_14 potentials, is adopted. Currents due to intermediate Delta-isobar excitations, are also included. The global contribution of the two-body currents turns out to be positive and provides an enhancement of the one-body transverse response ranging from about 20% for the lower momenta to about 10% for the higher ones. This finding is in agreement with the Green's Function Monte Carlo studies of the transverse Euclidean response in A=3,4 nuclei and contradicts previous results obtained within the Fermi gas and shell models. The tensor-isospin component of the correlation is found to be the leading responsible for such a behavior. The nuclear matter response is compared to recent experimental data on 40Ca and 56Fe.

description: Growing evidence has been accumulated for that some gas-rich dwarf galaxies are formed from material liberated by galaxy collisions and/or mergers. Also, gas-poor dwarf elliptical galaxies are often found in the central regions of clusters of galaxies. These observations suggest strongly that the formation of most dwarf galaxies is linked to galaxy interactions. Therefore, now seems like the right time to investigate the formation efficiency of such tidal dwarf galaxies. Adopting the galaxy interaction scenario proposed by Silk & Norman, we find that if only a few dwarf galaxies are formed in each galaxy collision, we are able to explain the observed morphology-density relations for both dwarf and giant galaxies in the field, groups of galaxies, and clusters of galaxies. It seems worthwhile noting that the tidal dwarf formation may be coupled with the transformation from gas-rich disk galaxies to early-type galaxies such as S0 and elliptical galaxies.

description: Color centers in diamond are a promising platform for quantum technologies, and understanding their interactions with the environment is crucial for these applications. We report a study of spin- lattice relaxation (T1) of the neutral charge state of the silicon vacancy center in diamond. Above 20 K, T1 decreases rapidly with a temperature dependence characteristic of an Orbach process, and is strongly anisotropic with respect to magnetic field orientation. As the angle of the magnetic field is rotated relative to the symmetry axis of the defect, T1 is reduced by over three orders of magnitude. The electron spin coherence time (T2) follows the same temperature dependence but is drastically shorter than T1. We propose that these observations result from phonon-mediated transitions to a low lying excited state that are spin conserving when the magnetic field is aligned with the defect axis, and we discuss likely candidates for this excited state.

description: In June, a member of the Carnegie Mellon bagpipe band piped the North American Serials Interest Group to the opening of its 14th national conference. Program organizers had drafted Rush Miller, University of Pittsburgh's Library Director, and me for a program about the Association of College and Research Libraries' (ACRL) redefining scholarship initiatives. Privately, Miller had challenged me to demonstrate how articles in the Journal of Academic Librarianship (JAL) fit into that construct. Based on the resulting program, this editorial demonstrates the value of the redefining scholarship work and suggests initiatives for further research in each of the four categories, with some additional comments on new developments. My thesis is that research in librarianship fits well into a system that can be applied to all disciplines. Doing research, talking about it on campus, and publishing it in refereed journals does increase campus respect both for the field of librarianship and for individual librarians.
Radiative Lifetime of Excitons in Carbon Nanotubes

description: We calculate the radiative lifetime and energy bandstructure of excitons in semiconducting carbon nanotubes, within a tight-binding approach. In the limit of rapid interband thermalization, the radiative decay rate is maximized at intermediate temperatures, decreasing at low temperature because the lowest-energy excitons are optically forbidden. The intrinsic phonons cannot scatter excitons between optically active and forbidden bands, so sample-dependent extrinsic effects that break the symmetries can play a central role. We calculate the diameter-dependent energy splittings between singlet and triplet excitons of different symmetries, and the resulting dependence of radiative lifetime on temperature and tube diameter.

description: At its annual Midwinter meeting in January 1999, Journal of Academic Librarianship board members discussed the ramifications of Elsevier's recent acquisition of the title. The thesis of this resulting editorial is that academic librarians who talk to their faculties about transforming their scholarly communications by moving away from commercial publishers cannot concurrently serve on an Elsevier-controlled journal board. Only consonant discussions and actions can undergird the integrity and moral force needed to be effective in the academy. The rationale of those leaving the board involves a discussion of journal microenvironment, the journal macroenvironment, the contribution to librarianship, the balance between responsibilities to campus and the profession, and the endgame. JAL readers are encouraged to communicate their reactions to gstclair@andrew.cmu.edu. These comments will be posted on the home page at www.suffolk.edu/admin/sawlib/jal/jalhomep.htm.

description: We construct the general static solution to the supergravity action containing gravity, the dilaton and a set of antisymmetric forms describing the intersecting branes delocalized in the relative transverse dimensions. The solution is obtained by reducing the system to a set of separate Liouville equations (the intersection rules implying the separability); it contains the maximal number of free parameters corresponding to the rank of the differential equations. Imposing the requirement of the absence of naked singularities, we show that the general configurations are restricted to two and only two classes: the usual asymptotically flat intersecting branes, and the intersecting branes some of which are asymptotically flat and some approach the linear dilaton background at infinity. In both cases the configurations are black. These are supposed to be relevant for the description of the thermal phase of the QFT's in the corresponding Domain-Wall/QFT duality.

UV Background-Induced Bifurcation of the Galactic Morphology

Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Based upon a novel paradigm of the galaxy formation under UV background, the evolutionary bifurcation of pregalactic clouds is confronted with observations on elliptical and spiral galaxies. The theory predicts that the dichotomy between the dissipational and dissipationless galaxy formation stems from the degree of self-shielding from the UV background radiation. This is demonstrated on a bifurcation diagram of collapse epochs versus masses of pregalactic clouds. Using the observed properties, the collapse epochs are assessed for each type of galaxies with attentive mass estimation. By the direct comparison of the theory with the observations, it turns out that the theoretical bifurcation branch successfully discriminates between elliptical and spiral galaxies. This suggests that the UV background radiation could play a profound role for the differentiation of the galactic morphology into the Hubble sequence.

description: Private cloud infrastructures are now widely deployed and adopted across technology industries and research institutions. Although cloud computing has emerged as a reality, it is now known that a single cloud provider cannot fully satisfy complex user requirements. This has resulted in a growing interest in developing hybrid cloud solutions that bind together distinct and heterogeneous cloud infrastructures. In this paper we describe the orchestration approach for heterogeneous clouds that has been implemented and used within the INDIGO-DataCloud project. This orchestration model uses existing open-source software like OpenStack and leverages the OASIS Topology and Specification for Cloud Applications (TOSCA) open standard as the modeling language. Our approach uses virtual machines and Docker containers in an homogeneous and transparent way providing consistent application deployment for the users. This approach is illustrated by means of two different use cases in different scientific communities, implemented using the INDIGO-DataCloud solutions.

description: We establish necessary and sufficient conditions for the existence of factorizable steady states of the Generalized Zero Range Process. This process allows transitions from a site $i$ to a site $i+q$ involving multiple particles with rates depending on the content of the site $i$, the direction $q$ of movement, and the number of particles moving. We also show the sufficiency of a similar condition for the continuous time Mass Transport Process, where the mass at each site and the amount transferred in each transition are continuous variables; we conjecture that this is also a necessary condition.

description: Aims: To assess clinical characteristics and factors associated with glycated hemoglobin (HbA1c) reduction in type 2 diabetes (T2DM) patients initiating glucagon-like peptide-1 receptor agonists (GLP-1RAs). Methods: Retrospective cohort study in patients with T2DM who initiated GLP-1RAs between 2007 and 2014 in primary health care centers in Catalonia (Spain). We evaluated changes in HbA1c and body weight at 6–12 months, and factors independently associated with achieving ≥1% HbA1c target reduction. Results: Overall, 4242 patients (47.9% male; mean BMI 37.5 kg/m2) initiated a GLP-1RA. At 6–12 months, the mean HbA1c level decreased from the baseline 8.8% to 7.7% (−1.0%; SD = 1.6). A 1% reduction in HbA1c was observed in 47.2% of patients. Patients lost a mean of 3.6 kg (SD = 6.2). Sixty percent of patients reduced both HbA1c and body weight, and 17% achieved only one of these targets. Independent determinants of a 1% HbA1c reduction were baseline HbA1c, age, diabetes duration and being on insulin treatment. Reduction in weight or HbA1c and the proportion of patients achieving a HbA1c reduction of ≥1% was significantly larger among subjects prescribed liraglutide than exenatide and lixisenatide. Conclusions: In this real-world, retrospective study, the magnitude of HbA1c and body weight reductions after addition of a GLP-1RA were similar to those observed in randomized controlled trials. Approximately 60% of patients attained reductions in both HbA1c and body weight, and there were significant differences among different drugs from this therapeutic group.
Off-critical local height probabilities on a plane and critical partition functions on a cylinder

description: We compute off-critical local height probabilities in regime-III restricted solid-on-solid models in a $4 N$-quadrant spiral geometry, with periodic boundary conditions in the angular direction, and fixed boundary conditions in the radial direction, as a function of $N$, the winding number of the spiral, and $τ$, the departure from criticality of the model, and observe that the result depends only on the product $N \, τ$. In the limit $N \rightarrow 1$, $τ\rightarrow τ_0$, such that $τ_0$ is finite, we recover the off-critical local height probability on a plane, $τ_0$-away from criticality. In the limit $N \rightarrow \infty$, $τ\rightarrow 0$, such that $N \, τ= τ_0$ is finite, and following a conformal transformation, we obtain a critical partition function on a cylinder of aspect-ratio $τ_0$. We conclude that the off-critical local height probability on a plane, $τ_0$-away from criticality, is equal to a critical partition function on a cylinder of aspect-ratio $τ_0$, in agreement with a result of Saleur and Bauer.

description: Batrachochytrium dendrobatidis (Bd), a causative agent of chytridiomycosis, is decimating amphibian populations around the world. Bd belongs to the chytrid lineage, a group of early-diverging fungi that are widely used to study fungal evolution. Like all chytrids, Bd develops from a motile form into a sessile, growth form, a transition that involves drastic changes in its cytoskeletal architecture. Efforts to study Bd cell biology, development, and pathogenicity have been limited by the lack of genetic tools with which to test hypotheses about underlying molecular mechanisms. Here, we report the development of a transient genetic transformation system for Bd. We used electroporation to deliver exogenous DNA into Bd cells and detected transgene expression for up to three generations under both heterologous and native promoters. We also adapted the transformation protocol for selection using an antibiotic resistance marker. Finally, we used this system to express fluorescent protein fusions and, as a proof of concept, expressed a genetically encoded probe for the actin cytoskeleton. Using live-cell imaging, we visualized the distribution and dynamics of polymerized actin at each stage of the Bd life cycle, as well as during key developmental transitions. This transformation system enables direct testing of key hypotheses regarding mechanisms of Bd pathogenesis. This technology also paves the way for answering fundamental questions of chytrid cell, developmental, and evolutionary biology.

description: In April, I began work as the University Librarian at Carnegie Mellon University in Pittsburgh, Pennsylvania. While my duties as the editor of the Journal of Academic Librarianship (JAL) remain the same, this new environment is already changing my perspective on librarianship and its future.

Readers and contributors to JAL are aware that most of the decisions about content are made by the Journal's referees. But, at the margin, Peter Hernon and I push in certain directions. This editorial suggests where some subtle changes in those emphases may begin to occur.

description: We apply the average null energy condition to obtain upper bounds on the three-point function coefficients of stress tensors and a scalar operator, $\langle TT {\cal O } \rangle,$ in general CFTs. We also constrain the gravitational anomaly of $U(1)$ currents in four-dimensional CFTs, which are encoded in three-point functions of the form $\langle TT J \rangle$. In theories with a large $N$ AdS dual we translate these bounds into constraints on the coefficient of a higher derivative bulk term of the form $\int ϕ\hspace{.5mm} W^2 $. We speculate that these bounds also apply in de-Sitter. In this case our results constrain inflationary observables, such as the amplitude for chiral gravity waves that originate from higher derivative terms in the Lagrangian of the form $ϕ\hspace{.5mm}W W^*$.

In addition, we investigate the effects of a nonzero normal stress. The results are shown to be useful in predicting the structure and polarization of perovskite oxide thin films and superlattices.

description: We have conducted a search for new stars of high proper motion ($\geq$0.4 arcsec yr$^{-1}$) using POSS II fields for which an extra IIIaF (red) plate of good quality exists, along with useable IIIaJ (blue) and IV-N (infrared) plates taken at epochs differing by a minimum of 1.5 years. Thirty-five fields at Galactic latitudes $|b| \geq$ 20$^o$ were measured, covering some 1378 deg$^2$, or 3.3% of the sky. Searches with three plate combinations as well as all four plates were also made. Seven new stars were found with $μ\geq$0.5 arcsec yr$^{-1}$, which were therefore missed in the Luyten Half Second (LHS) Catalog. One of these is a common proper motion binary consisting of two subdwarf M stars; another is a cool white dwarf with probable halo kinematics. As a test of our completeness -- and of our ability to test that of Luyten -- 216 of 230 catalogued high proper motion stars were recovered by the software, or 94%. Reasons for incompleteness of the LHS are discussed, such as the simple fact that POSS II plates have deeper limiting magnitudes and greater overlap than did POSS I. Nonetheless, our results suggest that the LHS is closer to 90% complete than recent estimates in the literature (e.g 60%), and we propose a reason to account for one such lower estimate. The conclusion that the LHS Catalog is more complete has implications for the nature of the halo dark matter. In particular it strengthens the constraint on the local density of halo stars, especially white dwarfs at M$_V\sim$17-18.

In this scenario, the cosmological constant is a de Sitter vacuum. The vacuum is metastable and would decay into an anti-de Sitter vacuum finally. Then the catastrophe of the big crunch appears. In this paper by conjecturing the physics at the Planck scale, we modify the definition of the Hawking temperature. Hinted by this modification, we modify the Friedmann equation. we find that this avoid the singularity and gives a bouncing cosmological model.

description: We address parameter estimation in two-level systems exhibiting level anti-crossing and prove that universally optimal strategies for parameter estimation may be designed, that is, we may find a parameter independent measurement scheme leading to the ultimate quantum precision independently on the nature and the value of the parameter of interest. Optimal estimation may be achievable also at high temperature depending on the structure of the two-level Hamiltonian. Finally, we show that no improvement is achievable by dynamical strategies and discuss examples of applications.

description: As a result of multiple mini-jet production, initial conditions of the QCD plasma formed in ultrarelativistic nuclear collisions may be inhomogeneous, with large fluctuations of the local energy density (hot spots), and turbulent, with a chaotic initial transverse velocity field. Assuming rapid local thermalization, the evolution of such plasmas is computed using longitudinal boost-invariant 3+1-dimensional hydrodynamics. We compare the evolution in case that the speed of sound in the plasma is constant to one resulting from an equation of state involving a strong first order transition, with a minimum of the velocity of sound as a function of energy density. We find that azimuthally asymmetric fluctuations and correlations of the transverse energy flow can develop in both cases due to the initial inhomogeneities. Hot spots also enhance significantly high-transverse momenta direct photon yields. In the case with a phase transition, the hadronization surface evolves into an unusual foam-like structure. Also in that case, we find that hadronization is considerably delayed relative to the ideal gas case, just as previous studies have found for homogeneous initial conditions. The time-delay signature of a rapid cross-over transition region in the QCD equation of state (as observable via meson interferometry) is thus found to be remarkably robust to uncertainties in the initial conditions in heavy-ion reactions.

description: Results of an SiO maser survey for the late-type stars selected by the IRTS (Infrared Telescope in Space) are presented. We have detected SiO J=1-0, v=1 and/or v=2 lines in 27 stars out of 59 stars. The maser intensity increases with the depth of the H2O absorption in the infrared spectra and redness of the 2.2 and 12 micron color. The column densities of the water vapor in the target stars are estimated from the depth of the water absorption in the IRTS spectra. We found that the SiO maser was detected mostly in the stars with the column density of water vapor higher than 3x10^19-3x10^20 cm^-2. We further estimate the density of hydrogen molecules in the outer atmosphere corresponding to these column densities, obtaining 10^9 - 10^10 cm^-3 as a lower limit. These values are roughly in agreement with the critical hydrogen density predicted by models for the excitation of the SiO masers. It is possible that the SiO masers are excited in clumps with even higher than this density. The present results provide useful information on the understanding of the physical conditions of the outer atmospheres in late-type stars.

description: We report flare ribbons approach (FRA) during a multiple-ribbon M-class flare on 2015 November 4 in NOAA AR 12443, obtained by the Interface Region Imaging Spectrograph and the Solar Dynamics Observatory. The flare consisted of a pair of main ribbons and two pairs of secondary ribbons. The two pairs of secondary ribbons were formed later than the appearance of main ribbons, with respective time delays of 15 and 19 minutes. The negative-polarity main ribbon spread outward faster than the first secondary ribbon with the same polarity in front of it, and thus the FRA was generated. Just before their encounter, the main ribbon was darkening drastically and its intensity decreased by about 70% in 2 minutes, implying the suppression of main-phase reconnection that produced two main ribbons. The FRA caused the deflection of the main ribbon to the direction of secondary ribbon with a deflection angle of about 60 degree. Post-approach arcade was formed about 2 minutes later and the downflows were detected along the new arcade with velocities of 35-40 km/s, indicative of the magnetic restructuring during the process of FRA. We suggest that there are three topological domains with footpoints outlined by the three pairs of ribbons. Close proximity of these domains leads to deflection of the ribbons in agreement with the magnetic field topology.

description: In "The Changing Role of the Library Director: Fund- Raising and the Academic Library" in this issue, Susan K. Martin does exemplary work in defining the responsibilities of a Library Director in gaining additional support for the library. As that article went through the refereeing and revision processes, I decided to write a complementary editorial to reinforce the importance of development initiatives in libraries. The points I want to emphasize are, first, making the case and identifying and cultivating prospects and, second, broad involvement among libraries' faculty and staff. This article and editorial discuss how successful development efforts can allow the library to do more with more in an environment where few additional college and university resources are forthcoming.

description: Academic librarians practice in an increasingly turbulent information environment. Writing in the NACUBO Journal, Brian Hawkins recently laid out an alarming scenario for the future of academic libraries as collectors of the world's cumulative published knowledge. While most academic librarians had thought of information as doubling at an alarming rate of every 10 years, Hawkins asserts that the body of information now doubles every two to three years. His data indicate that while information production is increasing exponentially, library budgets have not and will not be able to keep up with the rising costs. His analysis shows that the aggregate of all academic libraries now collects about six percent of total available knowledge and that within 20 years that figure will drop to one half of one percent.1 The implications of that drop for librarian's roles as selectors will be the focus of a future editorial.

description: Here at Penn State, we have just broken ground for the Paterno Library in honor of Joseph V. and Suzanne P. Paterno. Joe Paterno is Professor and Head Football Coach and Sue is a noted volunteer for a variety of good causes. Because the Paternos are such active supporters of the Libraries, I have many opportunities to learn from their ideas about higher education. Recently, Coach Paterno was recounting his days as a student at Brown University and remembering a particular professor who believed in a divine discontent with the status quo. Paterno concluded that "A great university is in the forefront of change." The challenges for higher education come from the impact of technology, the idea of the university as an instrument of social change, and the economics of education
Rotational correlation and dynamic heterogeneity in a kinetically constrained lattice gas

description: We study dynamical heterogeneity and glassy dynamics in a kinetically constrained lattice gas model which has both translational and rotational degrees of freedom. We find that the rotational diffusion constant tracks the structural relaxation time as density is increased whereas the translational diffusion constant exhibits a strong decoupling. We investigate distributions of exchange and persistence times for both the rotational and translational degrees of freedom and compare our results on the distributions of rotational exchange times to recent single molecule studies.

description: In this letter, we relate the free energy of the 0A matrix model to the sum of topological and anti-topological string amplitudes. For arbitrary integer multiples of the matrix model self-dual radius we describe the geometry on which the corresponding topological string propagates. This geometry is not the one that follows from the usual ground ring analysis, but in a sense its "holomorphic square root". Mixing of terms for different genus in the matrix model free energy yields one-loop terms compatible with type II strings on compact Calabi-Yau target spaces. As an application, we give an explicit example of how to relate the 0A matrix model free energy to that of a four-dimensional black hole in type IIB theory, compactified on a compact Calabi-Yau. Variables, Legendre transforms, and large classical terms on both sides match perfectly.

title: The fitness landscape of a community of Darwin’s finches

description: Divergent natural selection should lead to adaptive radiation—that is, the rapid evolution of phenotypic and ecological diversity originating from a single clade. The drivers of adaptive radiation have often been conceptualized through the concept of “adaptive landscapes,” yet formal empirical estimates of adaptive landscapes for natural adaptive radiations have proven elusive. Here, we use a 17-year dataset of Darwin’s ground finches (Geospiza spp.) at an intensively studied site on Santa Cruz (Galápagos) to estimate individual apparent lifespan in relation to beak traits. We use these estimates to model a multi-species fitness landscape, which we also convert to a formal adaptive landscape. We then assess the correspondence between estimated fitness peaks and observed phenotypes for each of five phenotypic modes (G. fuliginosa, G. fortis [small and large morphotypes], G. magnirostris, and G. scandens). The fitness and adaptive landscapes show 5 and 4 peaks, respectively, and, as expected, the adaptive landscape was smoother than the fitness landscape. Each of the five phenotypic modes appeared reasonably close to the corresponding fitness peak, yet interesting deviations were also documented and examined. By estimating adaptive landscapes in an ongoing adaptive radiation, our study demonstrates their utility as a quantitative tool for exploring and predicting adaptive radiation.
