description: In this paper we introduce and exploit the real replica approach for a minimal generalization of the Hopfield model, by assuming the learned patterns to be distributed accordingly to a standard unit Gaussian. We consider the high storage case, when the number of patterns is linearly diverging with the number of neurons. We study the infinite volume behavior of the normalized momenta of the partition function. We find a region in the parameter space where the free energy density in the infinite volume limit is self-averaging around its annealed approximation, as well as the entropy and the internal energy density. Moreover, we evaluate the corrections to their extensive counterparts with respect to their annealed expressions. The fluctuations of properly introduced overlaps, which act as order parameters, are also discussed.

description: Hamiltonian Boundary Value Methods are a new class of energy preserving one step methods for the solution of polynomial Hamiltonian dynamical systems. They can be thought of as a generalization of collocation methods in that they may be defined by imposing a suitable set of extended collocation conditions. In particular, in the way they are described in this note, they are related to Gauss collocation methods with the difference that they are able to precisely conserve the Hamiltonian function in the case where this is a polynomial of any high degree in the momenta and in the generalized coordinates. A description of these new formulas is followed by a few test problems showing how, in many relevant situations, the precise conservation of the Hamiltonian is crucial to simulate on a computer the correct behavior of the theoretical solutions.

description: Poly(ADP-ribose) polymerases (PARPs) play key roles in DNA damage repair pathways in eukaryotic cells. Human PARPs 1 and 2 are catalytically activated by damage in the form of both double-strand and single-strand DNA breaks. Recent structural work indicates that PARP2 can also bridge two DNA double-strand breaks (DSBs), revealing a potential role in stabilizing broken DNA ends. In this paper, we have developed a magnetic tweezers-based assay in order to measure the mechanical stability and interaction kinetics of proteins bridging across the two ends of a DNA DSB. We find that PARP2 forms a remarkably stable mechanical link (rupture force ~85 pN) across blunt-end 5'-phosphorylated DSBs and restores torsional continuity allowing DNA supercoiling. We characterize the rupture force for different overhang types and show that PARP2 switches between bridging and end-binding modes depending on whether the break is blunt-ended or has a short 5' or 3' overhang. In contrast, PARP1 was not observed to form a bridging interaction across blunt or short overhang DSBs and competed away PARP2 bridge formation, indicating that it binds stably but without linking together the two broken DNA ends. Our work gives insights into the fundamental mechanisms of PARP1 and PARP2 interactions at double-strand DNA breaks and presents a unique experimental approach to studying DNA DSB repair pathways.

description: Paluai, also known as Pam-Baluan, is an Oceanic language spoken on Baluan Island in Manus Province, Papua New Guinea. The total number of speakers is estimated to be 2,000-3,000. Although Paluai is relatively vibrant and passed on to younger generations, bilingualism with Tok Pisin is ubiquitous and there may be language shift taking place in some domains. The article discusses these issues, in addition to the language’s embeddedness in its environment and socio-cultural context, both related to elements of present-day life (economy, education, religion) and more traditional aspects such as song and music, customary ceremonies and naming practices.

description: We study the formation and evolution of a turbulent spectrum of Alfvén waves driven by reflection off the solar wind density gradients, starting from the coronal base up to 17 solar radii, well beyond the Alfvénic critical point. The background solar wind is assigned and 2D shell models are used to describe nonlinear interactions. We find that the turbulent spectra are influenced by the nature of reflected waves. Close to the base, these give rise to a flatter and steeper spectrum for the outgoing and reflected waves respectively. At higher heliocentric distance both spectra evolve toward an asymptotic Kolmogorov spectrum. The turbulent dissipation is found to account for at least half of the heating required to sustain the background imposed solar wind and its shape is found to be determined by the reflection-determined turbulent heating below 1.5 solar radii. Therefore reflection and reflection-driven turbulence are shown to play a key role in the accelerationof the fast solar wind and origin of the turbulent spectrum found at 0.3 AU in the heliosphere.

Nonequilibrium Forces Between Neutral Atoms Mediated by a Quantum Field

Year: 2010
Subjects: subject: Quantum Physics (quant-ph)

description: We study all known and as yet unknown forces between two neutral atoms, modeled as three dimensional harmonic oscillators, arising from mutual influences mediated by an electromagnetic field but not from their direct interactions. We allow as dynamical variables the center of mass motion of the atom, its internal degrees of freedom and the quantum field treated relativistically. We adopt the method of nonequilibrium quantum field theory which can provide a first principle, systematic and unified description including the intrinsic field fluctuations and induced dipole fluctuations. The inclusion of self-consistent back-actions makes possible a fully dynamical description of these forces valid for general atom motion. In thermal equilibrium we recover the known forces -- London, van der Waals and Casimir-Polder forces -- between neutral atoms in the long-time limit but also discover the existence of two new types of interatomic forces. The first, a `nonequilibrium force', arises when the field and atoms are not in thermal equilibrium, and the second, which we call an `entanglement force', originates from the correlations of the internal degrees of freedom of entangled atoms.

Quantum Information Paradox: Real or Fictitious?

Publisher: name: arXiv
Year: 2009
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: One of the outstanding puzzles of theoretical physics is whether quantum information indeed gets lost in the case of Black Hole (BH) evaporation or accretion. Let us recall that Quantum Mechanics (QM) demands an upper limit on the acceleration of a test particle. On the other hand, it is pointed out here that, if a Schwarzschild BH would exist, the acceleration of the test particle would blow up at the event horizon in violation of QM. Thus the concept of an exact BH is in contradiction of QM and quantum gravity (QG). It is also reminded that the mass of a BH actually appears as an INTEGRATION CONSTANT of Einstein equations. And it has been shown that the value of this integration constant is actually zero. Thus even classically, there cannot be finite mass BHs though zero mass BH is allowed. It has been further shown that during continued gravitational collapse, radiation emanating from the contracting object gets trapped within it by the runaway gravitational field. As a consequence, the contracting body attains a quasi-static state where outward trapped radiation pressure gets balanced by inward gravitational pull and the ideal classical BH state is never formed in a finite proper time. In other words, continued gravitational collapse results in an "Eternally Collapsing Object" which is a ball of hot plasma and which is asymptotically approaching the true BH state with M=0 after radiating away its entire mass energy. And if we include QM, this contraction must halt at a radius suggested by highest QM acceleration. In any case no EH is ever formed and in reality, there is no quantum information paradox.

description: Nonylphenol ethoxylathe (NPEO) is a non-ionic surfactant of increasing concern, used in the formulation of laundry detergents and is frequently found in aquatic environments. The purpose of this study was to evaluate the effects of yeast extract (YE) and sodium fumarate (SF) in NPEO removal from domestic sewage under anaerobic conditions via central composite rotatable design (CCRD) and response surface methodology (RSM). Experiments were designed by varying concentrations of NPEO (1.6–5.8 mg L−1), YE (131.8–468.2 mg L−1) and SF (97.7–602.3 mg L−1) in batch reactors. SF and YE addition significantly influenced NPEO removal and CH4 production. Optimal values of YE (400 mg L−1) and SF (200 mg L−1) result in removal efficiency of 97% for 5 mg L−1 of NPEO, being mostly removed by biodegradation (86%). Meanwhile COD removal was 95% and methane yield was 134 ± 4 NmLCH4 g−¹CODremoved. The most abundant Bacteria genus identified were Macellibacteroides, Longilinea, Petrimonas and Proteiniphilum, while for Archaea, Methanosaeta and Methanoregula were the genera identified in higher relative abundances in optimized conditions.

Subjects: subject: Trading and Market Microstructure (q-fin.TR)

description: We study optimal trade execution strategies in financial markets with discrete order flow. The agent has a finite liquidation horizon and must minimize price impact given a random number of incoming trade counterparties. Assuming that the order flow $N$ is given by a Poisson process, we give a full analysis of the properties and computation of the optimal dynamic execution strategy. Extensions, whereby (a) $N$ is a fully-observed regime-switching Poisson process; and (b) $N$ is a Markov-modulated compound Poisson process driven by a hidden Markov chain, are also considered. We derive and compare the properties of the three cases and illustrate our results with computational examples.

description: The main compositions of pipe deposits from water distribution networks are potential iron resources, which can be used as catalysts to activate the combined hydrogen peroxide (HP) and peroxymonosulphate (PMS) system to produce reactive oxidative species (ROSs) to degrade pollutants. As a result, the degradation efficiency of chloramphenicol (CAP) in the HP/PMS dual-oxidant system could reach as high as 75.21% within 100 min with hydroxylamine (HA) assistance, and the dual-oxidant method had a wide pH applied range. To explore the mechanism of the dual-oxidant system in detail, several main affecting factors were investigated. In addition, the hydroxyl radical(•OH) was identified as the predominant radicals by Electron paramagnetic resonance (EPR) and the Radical scavenger test (RST). According to the competition kinetics experiment, the reaction rate of CAP with •OH was 1.933(± 0.052) × 1010 M−1s−1 in the HP/PMS dual-oxidant system, which was higher than the HP single oxidant system (6.10(± 0.036) × 109 M−1s−1). And the role of HA was explored , including reduction and competition. Six degradation products were detected by the liquid chromatography-mass spectrometry (LC-MS) and their toxicity was analyzed by the ecological structure-activity relationship (ECOSAR) predictive model. These findings further provide a theoretical basis for the practical application of pipe deposits and advance the development of in-situ removal of pollutants in water distribution networks in the future promisingly.

description: The volume under review, The Routledge Handbook of Language Revitalization, is part of the Routledge Handbook in Applied Linguistics series, and is described by the publisher as ‘the first comprehensive overview of the language revitalization movement’. In attempting to cover the topic of language revitalization as a whole its scope is indeed broader than most works in the field, and it provides an overview that should be welcome, at this point, given the time elapsed since the last publications of such scope (Hinton & Hale 2001; Grenoble & Whaley 2006). The Handbook is divided into two main sections: ‘Issues of Theory and Practice’ (Part 1) and ‘Regional Perspectives: Decolonizing and Globalizing Language Revitalization’ (Part 2). In the following review, Part 2 is addressed first and in greater detail, since it constitutes the Handbook’s most important and most original contribution to the field of language revitalization.

description: Let T be Takagi's continuous but nowhere-differentiable function. Using a representation in terms of Rademacher series due to N. Kono, we give a complete characterization of those points where T has a left-sided, right-sided, or two-sided infinite derivative. This characterization is illustrated by several examples. A consequence of the main result is that the sets of points where T'(x) is infinite have Hausdorff dimension one. As a byproduct of the method of proof, some exact results concerning the modulus of continuity of T are also obtained.

description: Chhitkul-Rakchham is a Tibeto-Burman (hereafter TB) language of the West-Himalayish subgroup spoken in the Kinnaur district of Himachal Pradesh, northern India. In the existing literature it is referenced as Chitkuli, a name based on one of the villages (Chhitkul, colloquially shortened to Chhul) where it is spoken, plus the suffix -i, an Indo-Aryan borrowing that has been added to the names of many TB languages of the area. It is also spoken in in Rakchham village (from rak, ‘stone’, and chham, ‘bridge’) and hence we name the language Chhitkul-Rakchham. It has no script and is the tongue of the high caste in both villages – the lower castes speak an Indo-Aryan variety. Chhitkul-Rakchham has borrowed heavily from Hindi, and, interestingly, borrows more from English than from the local TB lingua franca, Standard Kinnauri. The language is more endangered than previously reported.

description: Kawésqar is a language isolate spoken in Puerto Edén, Wellington Island, in the southernmost region of Chile. Puerto Edén, only accessible by sea, is a small village with approximately 100 inhabitants, a minority of whom are Kawésqar. Kawésqar people were nomad canoeists in the past, but since 1936 their life style and subsistence strategies were changed by contact with the Chilean institutions. Over the last forty years a considerable amount of research has been carried out on the language, allowing access to a substantial body of data about both the language and the culture. These studies include brief dictionaries, translated traditional narratives, a pedagogical grammar, two teaching handbooks, and a sound archive. However, the number of speakers is critically low, while conversational communicative events remain mostly undocumented.

description: Combining work of Serre and Zumbrun, Benzoni-Gavage, Serre, and Zumbrun, and Texier and Zumbrun, we propose as a mechanism for the onset of cellular instability of viscous shock and detonation waves in a finite-cross-section duct the violation of the refined planar stability condition of Zumbrun--Serre, a viscous correction of the inviscid planar stability condition of Majda. More precisely, we show for a model problem involving flow in a rectangular duct with artificial periodic boundary conditions that transition to multidimensional instability through violation of the refined stability condition of planar viscous shock waves on the whole space generically implies for a duct of sufficiently large cross-section a cascade of Hopf bifurcations involving more and more complicated cellular instabilities. The refined condition is numerically calculable as described in Benzoni-Gavage--Serre-Zumbrun.

description: The "Satellite/lunar laser ranging Characterization Facility" (SCF) of INFN-LNF in Frascati, Italy, is devoted to the characterization of the detailed thermal properties and the optical performance of laser- ranged payloads (the "SCF-test") for GNSS, Space Geodesy and Fundamental Physics applications [1][2]. The Optical Lab is a second LNF facility dedicated to the far field diffraction pattern (FFDP) industrial acceptance test of laser cube corner retroreflectors (CCR) for space applications. We tested about 200 flight CCRs to be deployed in space by imminent launches at the two LNF facilities. These launches are for the current American Global Navigation Satellite System Constellation, the GPS-2 by NASA and for the European VEGA Program, by ESA/ASI. Some of the tested CCRs are for undisclosed missions by other space agencies. Deep Space Gravity Probe (DSGP) is a mission led by NASA-JPL (S. Turyshev is the PI), proposed to NASA and to the ESA "Cosmic Vision" program to study the anomalous deceleration of the Pioneer 10 and 11 probes and other important interplanetary science topics. In the context of a three-year study on "Cosmology and Fundamental Physics" (COFIS) funded by ASI and led at national level by P. de Bernardis we designed a prototype laser-ranged test mass for the DSGP satellite formation. This mass is being built at LNF and will be SCF-Tested at the SCF. We are also collaborating with NASA-GSFC (J. McGarry et al) on the test of innovative CCRs for the GPS-3. The goal of this R&D is to convince the US Air Force and Department of Defense of the full functionality of the hollow retroreflector design. This is a prerequisite to propose the deployment of retroreflectors on the GPS-3, which, unlike GALILEO, is a military constellation.

Search for WIMPS Using Upward-Going Muons in MACRO
Creators: name: INFN Collaboration
Publisher: name: INFN Open Access Repository
Year: 1999

description: We present update results on the search for neutrino signal from the core of the Earth and of the Sun induced by Weakly Interacting Massive Particles (WIMPs). In this paper we concentrate on neutralinos as WIMP Candidates. The 971 and 642 events used respectively for the search from the Sun and from the Earth are compatible with the background of atmospheric neutrinos. Consequently we calculate flux limits for varoius search cones around these sources. Limits as a function of the neutralino mass are given and compared to the supersymmetric (SUSY) models.

description: Recent works have suggested that selection criteria based on MIR colors can be used to reveal a population of dust-enshrouded, extremely luminous quasars at z>1. However the X-ray spectral properties of these intriguing sources still remain largely unexplored. We report on an X-ray spectroscopic study of a sample of 44 very bright mid-IR galaxies with extreme mid-IR to optical flux ratios (MIR/O>2000). The X-ray coverage of the sample is highly inhomogeneous (from snap-shot 5 ks Chandra observations to medium-deep XMM exposures of 70 ks) and, consequently, a sizable fraction of them (~43%) remains undetected in the 0.5-10 keV band. The vast majority (95%) of the detected sources (23) show an absorption column density NH>10e22 cm-2 and, remarkably, we also find that 50% of them can be classified as Type 2 quasars on the basis of their absorption properties and X-ray luminosity. Moreover, most of the X-ray undetected sources show extreme mid-IR colors, consistent with being luminous AGN-powered objects, suggesting they might host heavily obscured (possibly Compton-thick) quasars in X-rays. This demonstrates that our selection criteria applied to a wide area survey is very efficient in finding a large number of Type 2 quasars at z > 1. The existence of this class of very powerful, obscured quasars at high z could have important implications in the context of the formation and cosmological evolution of accreting supermassive black holes and their host galaxies.

description: The main compositions of pipe deposits from water distribution networks are potential iron resource and can be used as catalyst to active the combined hydrogen peroxide(HP) and peroxymonosulfate(PMS) system to produce reactive oxidative species(ROSs) for pollutant degradation. As a result, the degradation efficiency of chloramphenicol (CAP) in the HP/PMS dual-oxidant system could reach to as high as 75.21% within 100min with hydroxylamine(HA) assistance and the dual-oxidant method had a wide pH applied range. In order to explore the mechanism of dual-oxidant system in detail, several key affecting factors were investigated. In addition, the hydroxyl radical(•OH) was identified as the predominant radicals by Electron paramagnetic resonance(EPR) and Radical scavenger test(RST). According to the competition kinetics, the reaction rate of CAP with •OH was 1.933(±0.052)×1010 M-1s-1 in HP/PMS dual-oxidant system, which was higher than the HP single oxidant system (6.10(±0.036)×109 M-1s-1). And the role of HA was explored in detail including reduction and competition. Six degradation product were detected by the liquid chromatography-mass spectrometry (LC-MS) and their toxicity was analyzed by the ecological structure activity relationships(ECOSAR) predictive model. These findings further provide a theoretical basis for the practical application of pipe deposits and promising advance the development of in-situ removal of pollutant in water distribution networks in future.

Sapé (Venezuela) -- Language Snapshot

name: Medina, Francia
Publisher: name: Language Documentation and Description
Year: 2019

description: Sapé is a language isolate traditionally spoken along the Karún and Upper Paragua rivers and their tributaries in the Bolivar State of Venezuela. While the Sapé have been a small group since their first mention in the historical record, the population has dwindled in the last few decades and as of 2011, only nine individuals self-identified as Sapé. The causes for this decrease are tied to intermarriages with larger groups in the area as well as to (introduced) diseases and, possibly, prior interethnic conflicts. Documentation of the language is scant but recent work has uncovered unpublished materials that might enrich the record. Fieldwork carried out in 2017 established that, in addition to two unconfirmed semi-speakers, there remained only one speaker of Sapé; it also expanded on previously-collected materials and gathered additional data. There may be other (semi-)speakers along the Karún River but this is still unconfirmed.

description: We argue that supersymmetric transformation could be applied across the heterojunction formed by joining of two mixed semiconductors. A general framework is described by specifying the structure of ladder operators at the junction for making quantitative estimation of physical quantities. For a particular heterojunction device, we show that an exponential grading inside a nanoscale doped layer is amenable to exact analytical treatment for a class of potentials distorted by the junctions through the solutions of transformed Morse-Type potentials.

description: The floods that hit Rio Grande do Sul (RS, Brazilian State of the South Region) in 2023 represented one of the largest climate disasters in Brazil's recent history. The event exposed not only the vulnerability of infrastructure and local communities, but also the challenges of government planning and management in the face of environmental crises. This article analyzes the main difficulties faced by the state and federal governments during the flood period, the emergency responses adopted, and the lessons taken from other cities in different countries that can be learned to strengthen disaster management in the future.
On the exact treatment of Time Dependent Self-Interaction Correction

description: We present a new formulation of the time-dependent self-interaction correction (TDSIC). It is derived variationally obeying explicitly the constraints on orthonormality of the occupied single-particle orbitals. The thus emerging rather involved symmetry condition amongst the orbitals is dealt with using two separate sets of (occupied) single-particle wavefunctions, related by a unitary transformation. The double-set TDSIC scheme is well suited for numerical implementation. We present results for laser-excited dynamics in a 1D model for a molecule and in fully fledged 3D calculations.

Gorwaa (Tanzania) -- Language Contexts
Creators: name: Harvey, Andrew
Publisher: name: Language Documentation and Description
Year: 2019

description: Gorwaa is a South Cushitic language, spoken in north-central Tanzania. The number of speakers is approximately 132,748, and though used frequently in rural areas, many speakers are shifting to Swahili for everyday use, especially in the larger towns. Gorwaa is the name of the ethnic group, as well as the name of the language. Gorwaa is closely related to the other South Cushitic languages of Tanzania, namely: Iraqw, Alagwa, and Burunge; there is a high degree of mutual intelligibility between Gorwaa and Iraqw. That being said, speakers from both communities consider themselves as two separate ethnic groups, and there are several salient lexical and morphosyntactic differences between Gorwaa and Iraqw. This paper provides an overview of the larger context in which Gorwaa is spoken. Section 2 sketches the history of its speaker community. Section 3 outlines the relationships (both genetic and areal) that exist between Gorwaa and other languages in the area. Section 4 provides details on language use and language attitudes (including speaker numbers, language vitality, and how speakers perceive Gorwaa). Section 5 explains the different names used (and currently in use) to label the Gorwaa language. Section 6 mentions important works about Gorwaa which precede this one....

description: In this paper we study the simplest deformation on a sequence of orthogonal polynomials, namely, replacing the original (or reference) weight $w_0(x)$ defined on an interval by $w_0(x)e^{-tx}.$ It is a well-known fact that under such a deformation the recurrence coefficients denoted as $α_n$ and $β_n$ evolve in $t$ according to the Toda equations, giving rise to the time dependent orthogonal polynomials, using Sogo's terminology. The resulting "time-dependent" Jacobi polynomials satisfy a linear second order ode. We will show that the coefficients of this ode are intimately related to a particular Painlevé V. In addition, we show that the coefficient of $z^{n-1}$ of the monic orthogonal polynomials associated with the "time-dependent" Jacobi weight, satisfies, up to a translation in $t,$ the Jimbo-Miwa $σ$-form of the same $P_{V};$ while a recurrence coefficient $α_n(t),$ is up to a translation in $t$ and a linear fractional transformation $P_{V}(α^2/2,-β^2/2, 2n+1+α+β,-1/2).$ These results are found from combining a pair of non-linear difference equations and a pair of Toda equations. This will in turn allow us to show that a certain Fredholm determinant related to a class of Toeplitz plus Hankel operators has a connection to a Painlevé equation.
