description: We study the problem of the gravitational collapse of an object as seen by an external observer. We assume that the resultant spacetime is a match of an external Vaidya spacetime with an interior Friedmann-Lemaître-Robertson-Walker (FRLW) spacetime of any spatial curvature and with a scalar field both minimally and non-minimally coupled to the metric. With the goal of studying a contracting (collapsing) object, for the initial moment of observation we take that its energy density and pressure are positive, that there are no trapping surfaces, and that the null energy condition (NEC) and the strong energy condition (SEC) are fulfilled. We show that there are many cases where singularities could be avoided for both the minimal and non-minimal couplings, although the contexts for so are very different in both cases. For the minimal coupling, the avoidance of singularities could happen either through evaporation or altogether, triggered by a violation of the SEC for a period of time. For the non-minimal coupling, the complete singularity avoidance happens only if evaporation takes place, and a temporary violation of the SEC does not thwart the formation of singularities. The above results show the relevance of the global (the whole spacetime) validity of energy conditions for the singularity theorems to be applicable; otherwise, the fate of a collapsing star is not known a priori. At the same time, the surface behavior of a collapsing body offers partial diagnostics of what happens in the inaccessible regions of spacetime to external observers. Our analyses suggest that a bounce behavior of the surface of the initially collapsing object is a fingerprint of the SEC violation in its interior, and that could be due to the existence of scalar fields there.

description: What (political) geography ought to be. Political geography between peace and war
Geography has been often accused of being a discipline useful, above all, to make war. But, at the end of the Nineteenth century, Kropotkin already envisaged a totally different use of geography, which, on the contrary, ought to be an instrument for mutual knowledge and understanding. The paper explores the complex relations between different attitudes toward wars (from the acceptance of it as a prosecution of politics to the total refusal of violence of modern pacifism) and the chances of using
political geography as a tool for justifying war or for making the conditions of a future of peace.

What (political) geography ought to be. La géographie politique pendant la paix et la guerre
La géographie été asouvent accusé d’être une discipline utile, d’abord, a faire la guerre. Cependant, à la fin du XIXe siècle, Kropotkin a envisagé déjà une utilisation radicalement différente de la géographie, qui, au contraire, doit être un instrument de connaissance et de compréhension mutuelle. Cette contribution explore les relations complexes entre les différentes attitudes de les géographes vis à vis des guerres (en partant de l’acceptation de la guerre celui-ci comme une continuation de la politique pour arriver au refus total de la violence du pacifisme moderne) et les chances d’utiliser la géographie politique comme un outil pour justifier la guerre ou pour créer les conditions d’un avenir de paix.

DISTRIBUTION.— Originally described from the ne. Atlantic and se. Indian Ocean, and subsequently recorded off Vanuatu in the sw. Pacific and off Brazil in the sw. Atlantic, in 1060–1699 m. Our Taiwan specimens are the first from this area and were taken at depths of 1098–1293 m.
REMARKS.— Macrosmia phalacra is turning out to be much more widely distributed than thought when originally described. The lack of specimens from the area between the North Atlantic and e. Indian Ocean leaves a perplexing distributional gap, but it may simply represent a collecting artifact.

description: We investigate the classical problem of motion of a mathematical pendulum with an oscillating pivot. This simple mechanical setting is frequently used as the prime example of a system exhibiting the parametric resonance phenomenon, which manifests itself by surprising stabilisation/destabilisation effects. In the classical case the pivot oscillations are described by a cosine wave, and the corresponding stability analysis requires one to investigate the behaviour of solutions to the Mathieu equation. This is not a straightforward procedure, and it does not lead to exact and simple analytical results expressed in terms of elementary functions. Consequently, the explanation of the parametric resonance phenomenon can be in this case obscured by the relatively involved technical calculations. We show that the stability analysis is much easier if one considers the pivot motion described by a non-smooth function -- a triangular or a nearly rectangular wave. The non-smooth pivot motion leads to the presence of singularities (Dirac distributions) in the corresponding Mathieu type equation, which seemingly further complicates the analysis. Fortunately, this is only a minor technical difficulty. Once the mathematical setting for the non-smooth forcing is settled down, the corresponding stability diagram is indeed straightforward to obtain, and the stability boundaries are, unlike in the classical case, given in terms of simple analytical formulae involving only elementary functions.
Politiche configurative e conflitti interconfigurativi

description: Configurative policies and interconfigurative conflicts
The article discusses, starting from the analysis of the forms taken by the policies of place, landscape and environment, the issue of territorial conflicts. It is a conflict that is activated due to issues related to spatial location, but that is often manifested in an involvement of the territorial dimension, as a request, for example, of a higher involvement of the territories in the decision-making issues. In this sense, the “political sense” of the territory, to which this monograph is based, takes on a foundation when generates, on different scales, forms of conflict that put into play rationality, visions, social expectations and objectives. The theme of interconfigurative conflict, as the set of controversies that compare public actions on the environment, landscape or place and that project effects on the communities, is developed through examples of wind
energy and geothermal energy.

Politiques configurative et conflits interconfigurative
L’article discute, à partir de l’analyse des formes adoptées par les politiques de lieu, le paysage et l’environnement, la question des conflits territoriaux. Il est un conflit qui est activé en raison de questions liées à la localisation spatiale, mais qui se manifeste souvent par une implication de la dimension territoriale dans la requête, par exemple, d’une plus grande participation des territoires dans les questions de prise de décision. Dans cette direction, le “sens politique” du territoire, à laquelle cette monographie est appelée, acquiert une base quand génère, à différentes échelles, formes de conflits qui mettent en jeu la rationalité, des visions, des attentes et des objectifs.
Le thème du conflit interconfigurative, comme l’ensemble des controverses
qui comparent les actions publiques centrées sur l’environnement, le paysage ou un lieu, projettent les effets sur les communautés, se développe à travers des exemples de l’énergie éolienne et l’énergie géothermique.

description: The so-called proton radius puzzle (the current discrepancy of proton radii determined from spectroscopic measurements in ordinary versus muonic hydrogen) could be addressed via an accurate measurement of the Rydberg constant, because the proton radius and the Rydberg constant values are linked through high-precision optical spectroscopy. We argue that, with manageable additional experimental effort, it might be possible to improve circular Rydberg state spectroscopy, potentially leading to an important contribution to the clarification of the puzzle. Our proposal involves circular and near-circular Rydberg states of hydrogen with principal quantum number around $n=18$, whose classical velocity on a Bohr orbit is slower than that of the fastest macroscopic man-made object, the Parker Solar Probe. We obtain improved estimates for the quality factor of pertinent transitions, and illustrate a few recent improvements in instrumentation which facilitate pertinent experiments.

description: We use high-resolution zoom-in simulations to study the fueling of the central galaxies by gas accretion from cosmological filaments at high redshifts, z>=2. Their parent haloes with similar DM masses of log(M_vir/M})~11.65, have been chosen at z=6, 4, and 2, in high/low overdensity environments, with the goal of comparing evolution within similar M at different z, under dual action of cosmological accretion and galactic outflows -- forming the circumgalactic medium (CGM). We focus on the filamentary and diffuse gas accretion within few virial radii, R_vir, down to the central galaxy. Using a hybrid d-web/entropy method we have mapped the gaseous filaments, and invoking particle kinematics allowed us to separate inflows from outflows, thus resolving thermodynamic and kinematic signatures of the CGM. We find that (1) The CGM is multiphase and not in thermodynamic or dynamic equilibrium; (2) accretion rates via individual filaments display a lower accretion rate and densities at lower redshifts. The inflow velocities along the filaments decrease with redshift, z~ 6-2, from 200-30 kms^-1 by a factor of 2; (3) Temperature within the filaments increases inside R_vir, faster at lower redshifts, in tandem with decrease in the accretion rate; (4) The filaments show a complex structure along their spines: a core radial flow surrounded by a lower density envelope. The core exhibits an elevated density and lower temperature, with no obvious metallicity gradient in the filament cross sections. It also tends to separate the filament into different infall velocity regions and density cores, thus producing a spaghetti-type flow; (6) Inside the inner ~ 30\,h^-1 kpc, the filaments develop the Kelvin-Helmholtz instability which ablates and dissolves them, and triggers turbulence along the filament spine; (7) Finally, the galactic outflows affect mostly the inner ~ 0.5R_vir~ 100 h^-1 kpc of the CGM.

description: In this paper, we describe a comprehensive algorithmic framework for solving mixed integer bilevel linear optimization problems (MIBLPs) using a generalized branch-and-cut approach. The framework presented merges features from existing algorithms (for both traditional mixed integer linear optimization and MIBLPs) with new techniques to produce a flexible and robust framework capable of solving a wide range of bilevel optimization problems. The framework has been fully implemented in the open-source solver MibS. The paper describes the algorithmic options offered by MibS and presents computational results evaluating the effectiveness of the various options for the solution of a number of classes of bilevel optimization problems from the literature.

Microscopic analysis of the superconducting quantum critical point: Finite temperature crossovers in transport near a pair-breaking quantum phase transition

description: A microscopic analysis of the superconducting quantum critical point realized via a pair-breaking quantum phase transition is presented. Finite temperature crossovers are derived for the electrical conductivity, which is a key probe of superconducting fluctuations. By using the diagrammatic formalism for disordered systems, we are able to incorporate the interplay between fluctuating Cooper pairs and electrons, that is outside the scope of a time-dependent Ginzburg Landau or effective bosonic action formalism. It is essential to go beyond the standard approximation in order to capture the zero temperature correction which results purely from the (dynamic) quantum fluctuations and dictates the behavior of the conductivity in an entire low temperature quantum regime. All dynamic contributions are of the same order and conspire to add up to a negative total, thereby inhibiting the conductivity as a result of superconducting fluctuations. On the contrary, the classical and the intermediate regimes are dominated by the positive bosonic channel. Our theory is applicable in one, two and three dimensions and is relevant for experiments on superconducting nanowires, doubly-connected cylinders, thin films and bulk in the presence of magnetic impurities, magnetic field or other pair-breakers. A window of non-monotonic behavior is predicted to exist as either the temperature or the pair-breaking parameter is swept.

Structure, expression and evolution of the 16 kilodalton heat shock protein gene family of C. elegans
Creators: name: Russnak, Roland Hans
Publisher: name: University of British Columbia
Year: 2010

description: Sequences coding for three related 16 kd heat shock proteins (hsps) of the nematode Caenorhabditis elegans were isolated and characterized. The extensive accumulation of hsp16 mRNA during heat stress facilitated the identification of two cDNAs, CEHS48 and CEHS41, which encoded hsp16 variants. These plasmids were selected by their ability to hybridize to mRNA which directed the synthesis of hspl6 in vitro, and were further characterized by sequence analysis. Two-dimensional gel electrophoresis of hspl6 synthesized in vitro from mRNA selected by hybridization to either of the cDNAs under conditions of low stringency revealed the existence of at least five electrophoretic variants with significantly different isoelectric points. The above cDNAs were used as specific probes to isolate recombinant bacteriophage containing C. elegans genomic DNA. Overlapping phage clones were used to define a region of approximately 30 kilobases. The genes coding for hsp16-48, previously identified by cDNA cloning, and for another 16 kd hsp designated hspl6-l were characterized by DNA sequencing. These two genes were arranged in a head-to-head orientation. Both the coding and flanking regions of these genes were located within a 1.9 kb region which was duplicated exactly to form a perfect 3.8 kb inverted repeat structure. This structure ended in unusual G + C-rich sequences 24 bp in length. The identity of the two arms of the inverted repeat at the nucleotide sequence level implied that the duplication event may have occurred relatively recently in evolution. Alternatively, gene conversion between the two modules could have maintained homology between the two gene pairs. Comparison of the hsp16-48 gene with its corresponding cDNA revealed the presence of a single, short intron. An intron of comparable length and in an analogous position was also found in the hsp16-1 gene. The introns separated variable and conserved regions within the amino acid sequences of the encoded heat shock proteins. A domain of approximatey 80 amino acids is contained within the conserved second exon and is homologous to a similar region in the small hsps of Drosophila, Xenopus, soybean and man as well as the a-crystallin protein of the vertebrate lens. Each hsp16 gene contained a TATA box upstream of the start of transcription. Promoter sequences, which have been shown to be required for heat inducibility in various systems, were located upstream of either TATA box Northern blot analysis showed that the hsp16-48 and hsp16-1 genes are expressed at levels approximately 20 - 40 fold lower than two closely related genes, hsp16-41 and hsp16-2, upon temperature elevation.

description: Although spectroscopic observations of RR Lyrae stars have now been carried out for almost a century, it is only recently that it has been identified that the hydrogen line exhibits three successive emissions in each pulsation cycle. The purpose of this study is to clarify the physical origin of these three emissions and their connection with atmospheric dynamics and the influence of Blazhko modulation on their intensity. From the value of the blueshift of the main H$α$ emission, the velocity of the hypersonic shock front was estimated between 100 and 150 $\pm 10$ km$\,$s$^{-1}$ (Mach number between 10 and 15). It has been established that the shock velocity increases from the minimum Blazhko to its maximum, and after that, gradually decreases to the Blazhko minimum to start growing again.
 This observational result is consistent with the shock model proposed in 2013 to explain the Blazhko effect. The intensity of the H$α$ emission increases with the shock velocity up to a maximum value around 137 km$\,$s$^{-1}$ and then decreases as the shock velocity increases further. This effect would be the consequence of the more and more important ionization of the atoms in the radiative shock wake. The second (blueshifted) H$α$ emission, is the consequence of an approximately constant supersonic compression (Mach number between 2 and 3) of the upper atmosphere falling on the photospheric layers, during 3 to 16% of the pulsation period. Finally, the third H$α$ emission (P-Cygni profile) would be the consequence of the expansion of the high atmosphere induced by the shock wave during its final weakening.

L’evento, che si è tenuto presso i locali dell’ex Istituto di Geografia dell’Università Sapienza di Roma, si è aperto con i saluti del Presidente nazionale dell’Associazione Italiana Insegnanti di Geografia, prof. Gino De Vecchis, ed è proseguito con gli interventi del prof. Gianfranco Battisti, direttore della rivista dal 1992 al 2003, del prof. Carlo Brusa, attuale direttore della rivista, della prof.ssa Daniela Pasquinelli d’Allegra, vicepresidente dell’AIIG, e del prof. Peris Persi, presidente nazionale AIIG dal 1991 al 2002, concludendosi con i saluti del prof. Andrea Riggio, segretario A.Ge.I (Brusa C., “L’Associazione Italiana Insegnanti di Geografia ha celebrato i 60 anni della nostra Rivista”, in Ambiente Società Territorio. Geografia nelle Scuole, 5-6, 2015). Rivivere la storia della rivista ha costituito un momento significativo per comprenderne i mutamenti avvenuti in corso d’opera e le scelte editoriali, quindi apprezzarne a pieno gli elementi che la contraddistinguono e ne definiscono l’identità.

description: We have measured the magnetotransport properties and Hall effect of a series of epitaxial NbN films grown on (100) oriented single crystalline MgO substrate under different conditions using reactive magnetron sputtering. Hall effect measurements reveal that the carrier density in NbN thin films is sensitive to the growth condition. The carrier density increases by a factor of 3 between the film with highest normal state resistivity (rho_n~3.83micro-Ohm-m) and lowest transition temperature (Tc~9.99K) and the film with lowest normal state resistivity (rho_n~0.94micro-Ohm-m) and highest transition temperature (Tc~16.11K) while the mobility of carriers does not change significantly except for the most resistive films. Our results show that the Tc of NbN is governed primarily by the carrier density rather than disorder scattering. By varying the carrier concentration during growth we can vary the effective disorder (kF_l) from the moderately clean limit to the dirty limit which makes this system ideal to study the interplay of carrier density and disorder on the superconducting properties of an s-wave superconductor.

description: Nell’universo filmico contemporaneo il ruolo occupato dagli spazi urbani
periferici ci appare sempre più, paradossalmente, centrale. A partire da un
film come L’odio (Kassowitz, 1995) sull’esplosione delle banlieu parigine diverse
delle tematiche affrontate da parte della cinematografia europea sembrano
riguardare proprio le relazioni che si innescano nelle periferie delle
città su tematiche che variano dalla migrazione al lavoro, dalla malavita allo
spaesamento.

Quantifying errors of the electron-proton/muon correlation functionals through the Kohn-Sham inversion of a two-component model system

description: The multi-component density functional theory is faced with the challenge of capturing various types of inter- and intra-particle exchange-correlation effects beyond those introduced by the conventional electronic exchange-correlation functionals. Herein, we focus on evaluating the electron-proton/muon correlation functionals appearing in molecular/condensed-phase systems where a proton/muon is treated as a quantum particle on equal footing with electrons, beyond the Born-Oppenheimer paradigm. Five recently developed local correlation functionals, i.e., the epc series and e$μ$c-1, are selected and their performances are analyzed by employing a two-particle model that includes an electron and a positively charged particle (PCP) with a variable mass, interacting through Coulombic forces, within a double harmonic trap. Using the Kohn-Sham (KS) inversion procedure, the exact two-component KS characterization of the model is deduced and its properties are compared to those derived from the considered functionals. The analysis demonstrates that these local functionals achieve their original parameterization objectives to reproduce the one-PCP densities and the electron-PCP correlation energies, but all fall short of reproducing the underlying PCP correlation potentials correctly. Moreover, a comprehensive error analysis reveals that the density-driven errors have a non-negligible contribution to the success of the considered functionals. Overall, the study shows the strengths as well as shortcomings of the considered functionals hopefully paving the way for designing more robust functionals in the future.

The influence of AGN nuclear parameters on the FRI/FRII dichotomy

description: We have investigated the influence of nuclear parameters such as black hole (BH) mass and photoionizing luminosity on the FRI/FRII transition in a sample of nearby (z<0.2) 3CR radio galaxies. The sample was observed with medium-resolution, optical spectroscopy and contains some galaxies with unpublished velocity dispersion measurements and emission-line fluxes. Measured velocity dispersions are 130-340 km/s with a mean of 216 km/s. Converting to BH mass, we find that the BH mass distribution is identical for FRIs and FRIIs, with a mean of approximately 2.5x10^8 Msun. We convert [OII] and [OIII] emission-line luminosities to photoionizing luminosity under the assumption that the gas is ionized by the nuclear UV continuum. Most of the galaxies with FRI morphology and/or low-excitation emission-line spectra have progressively lower BH masses at lower photoionizing (and jet) luminosities. This agrees with the Ledlow-Owen relation which states that the radio luminosity at the FRI/FRII transition depends on the optical luminosity of the host, L_radio ~ L_optical^1.8, because both L_radio and L_optical relate to AGN nuclear parameters. When recasting the Ledlow-Owen relation into BH mass versus photoionizing and jet luminosity, we find that the recasted relation describes the sample quite well. The FRI/FRII transition occurs at approximately an order of magnitude lower luminosity relative to the Eddington luminosity than the soft-to-hard transition in X-ray binaries. This difference is consistent with the Ledlow-Owen relation, which predicts a weak BH mass dependence in the transition luminosity. We conclude that the FRI/FRII dichotomy is caused by a combination of external and nuclear factors, with the latter dominating.
