Caluromys philander

description: Caluromys (Caluromys) philander   (Linnaeus, 1758)
TYPE MATERIAL AND TYPE LOCALITY: BMNH 67.4.12.414, the holotype by monotypy, consists of the fluid-preserved carcass and extracted skull of an adult female (Thomas, 1892; Jenkins and Knutson, 1983). The type locality is unknown, but it is often assumed to be Surinam (after Thomas, 1911).
 SYNONYMS: affinis Wagner, 1842; cajopolin Müller, 1776; cayopollin Schreber, 1777; cayopollin Kerr, 1792; dichurus Wagner, 1842; flavescens Brongniart, 1792; leucurus Thomas, 1904; trinitatis Thomas, 1894; venezuelae Thomas, 1903.
 DISTRIBUTION: Caluromys philander occurs in lowland rainforest and dry forests in north-central and eastern Venezuela; the Guianas; northern, central, and southeastern Brazil; and eastern Bolivia (Gardner, 2008: map 2).
 REMARKS: As currently recognized, Caluromys philander is unrevised and may represent a species complex, but published results are neither sufficient to distinguish valid taxa among the synonyms listed above nor among geographic populations currently lacking available names. Although López-Fuster et al. (2008) suggested that populations in Trinidad and northern Venezuela should be recognized as a distinct species, this inference was not supported by phylogenetic analyses of mtDNA sequence data reported by Voss et al. (2019). By contrast, the latter authors discovered that mtDNA sequences from eastern Bolivia were highly divergent from sequences obtained elsewhere in the known range of C. philander; unfortunately, voucher material from eastern Bolivia has yet to be examined for possibly diagnostic morphological traits.

description: We derive the scaling function for the one dimensional noisy Burgers equation in the two-soliton approximation within the weak noise canonical phase space approach. The result is in agreement with an earlier heuristic expression and exhibits the correct scaling properties.

description: The joint estimation of means and scatter matrices is often a core problem in multivariate analysis. In order to overcome robustness issues, such as outliers from Gaussian assumption, M-estimators are now preferred to the traditional sample mean and sample covariance matrix. These estimators are well established and studied in the real case since the seventies. Their extension to the complex case has drawn recent interest. In this letter, we derive the asymptotic performance of complex M-estimators for multivariate location and scatter matrix estimation.

description: We review recent observational and theoretical results concerning the presence of actinide nuclei on the surfaces of old halo stars and their use as an age determinant. We present model calculations which show that the observed universality of abundances for 56 < Z < 75 elements in these stars does not imply a unique astrophysical site for the r-process. Neither does it imply a universality of abundances of nuclei outside of this range. In particular, we show that a variety of astrophysical $r$-process models can be constructed which reproduce the same observed universal r-process curve for 56 < Z < 75 nuclei, yet have vastly different abundances for Z >= 75 and possibly Z <= 56 as well. This introduces an uncertainty into the use of the Th/Eu chronometer as a means to estimate the ages of the metal deficient stars. We do find, however, that the U/Th ratio is a robust chronometer. This is because the initial production ratio of U to Th is almost independent of the astrophysical nucleosynthesis environment. The largest remaining uncertainties in the U/Th initial production ratio are due to the input nuclear physics models.

description: Electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) are similar,but different quantum optical phenomena: EIT results from a Fano interference, whereas ATS is described by the AC-Stark effect. Likewise, despite their close resemblance, light-storage techniques based on the EIT memory protocol and the recently-proposed ATS memory protocol (E. Saglamyurek et al. Nature Photonics 12, 2018) are distinct: the EIT protocol relies on adiabatic elimination of absorption, whereas the ATS protocol is based on absorption. In this article, we elaborate on the distinction between EIT and ATS memory protocols through numerical analysis and experimental demonstrations in a cold rubidium ensemble. We find that their storage characteristics manifest opposite limits of the light-matter interaction due to their inherent adiabatic vs. non-adiabatic nature. Furthermore, we determine optimal memory conditions for each protocol and analyze ambiguous regimes in the case of broadband storage, where non-optimal memory implementations can possess characteristics of both EIT and ATS protocols. We anticipate that this investigation will lead to deeper understanding and improved technical development of quantum memories, while clarifying distinctions between the EIT and ATS protocols.

description: We embody the density matrix renormalization group method for the 19-vertex model on a square lattice; the 19-vertex model is regarded to be equivalent to the XY model for small interaction. The transfer matrix of the 19-vertex model is classified by the total number of arrows incoming into one layer of the lattice. By using this property, we reduce the dimension of the transfer matrix appearing in the density matrix renormalizaion group method and obtain a very nice value of the conformal anomaly which is consistent with the value at the Berezinskii-Kosterlitz-Thouless transition point.

description: Data anonymization is crucial to allow the widespread adoption of some technologies, such as smart meters. However, anonymization techniques should be evaluated in the context of a dataset to make meaningful statements about their eligibility for a particular use case. In this paper, we therefore analyze the suitability of continuous ks-anonymization with CASTLE for data streams generated by smart meters. We compare CASTLE’s continuous, piecewise ks-anonymization with a global process in which all data is known at once, based on metrics like information loss and properties of the sensitive attribute. Our results suggest that continuous ks-anonymization of smart meter data is reasonable and ensures privacy while having comparably low utility loss.
Quantum interest for scalar fields in Minkowski spacetime

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The quantum interest conjecture of Ford and Roman states that any negative energy flux in a free quantum field must be preceded or followed by a positive flux of greater magnitude, and the surplus of positive energy grows the further the positive and negative fluxes are apart. In addition, the maximum possible separation between the positive and negative energy decreases the larger the amount of negative energy. We prove that the quantum interest conjecture holds for arbitrary fluxes of non-interacting scalar fields in 4D Minkowski spacetime, and discuss the consequences in attempting to violate the second law of thermodynamics using negative energy. We speculate that quantum interest may also hold for the Electromagnetic and Dirac fields, and might be applied to certain curved spacetimes.

description: The transmission of acoustic phonons is an important element in the design and performance of nano-mechanical devices operating in the mesoscopic limit. Analytic expressions for the power transmission coefficient, T, exist only in the low-frequency (quasi-static) limit described by thin-plate elastic theory, and for well-defined elastic wave-guiding geometries. We compare two numerical techniques based on finite-element computations to determine the frequency dependence of T for arbitrary phonon scattering structures. Both methods take into account acoustic mode conversion to acoustic and optical modes. In one case, phase and amplitude of complex-valued reflected waves are determined and related to transmission through a Fresnel equation, while in the other the magnitude of the transmitted mechanical power is directly calculated. The numerical robustness of these methods is demonstrated by considering the transmission across an abrupt junction in a rectangular elastic beam, a well-known problem of considerable importance in mesoscopic device physics. The simulations presented extend the standard results for acoustic phonon transmission at an abrupt junction, and are in good agreement with analytic predictions from thin-plate elastic theory in the long-wavelength limit. More generally, the numerical methods developed provide an effective tool for calculating acoustic mode energy loss in nano-mechanical resonators through mode conversion and heat transfer in arbitrary mesoscopic structures.

description: In the absence of Lorentz symmetry, the pseudospin-1 counterpart of Weyl fermion (feroton) with linear dispersions and an exact flat band can emerge in condensed matter systems. The flat band branch of feroton is equivalent to the longitudinal photon in Maxwell theory, which is a redundant degree of freedom due to the emergent (fermionic) gauge symmetry. Upon coupling to an external magnetic field, the fermionic guage symmetry is broken and the flat band ferotons become gapless excitations characterized by Landau level indices ($n>1$). In the long wave length limit, these gapless modes are of the opposite chirality to the chiral anomaly related zero Landau level, which leads to much more plentiful magnetic transport properties. To further explore the novel properties of these gapless modes, we investigate the quantum oscillation through a generalized Lieb lattice model. We find an extra oscillating behavior which indicates the existence of these exotic gapless modes. We collect known {\it ab initio} calculation data from literature and discuss the possibility of realizing the semi-metallic feroton gas in real materials.

description: Two extensions of ideas lying in the basis of the inflationary scenario of the early Universe and their effect on the large scale structure of the present-day Universe are discussed. The first of them is the possibility of fast phase transitions in physical fields other than an inflaton scalar field during inflation and nor far from the end of it. This results in the appearance of specific features in the inflaton effective potential which, in turn, lead to the generation of localized spikes in the primordial perturbation spectrum. At present, there seems to exist one scale in the spectrum, $k=0.05h$ Mpc$^{-1}$, around which we might see something of this type. The second one is the possibility that we are living at the beginning of a new inflation-like era now. Then observations of clustering of high-redshift objects can provide information sufficient for the unambiguous determination of the effective potential of a corresponding present inflaton scalar field.

description: Modern microprocessors are equipped with Single Instruction Multiple Data (SIMD) or vector instructions which expose data level parallelism at a fine granularity. Programmers exploit this parallelism by using low-level vector intrinsics in their code. However, once programs are written using vector intrinsics of a specific instruction set, the code becomes non-portable. Modern compilers are unable to analyze and retarget the code to newer vector instruction sets. Hence, programmers have to manually rewrite the same code using vector intrinsics of a newer generation to exploit higher data widths and capabilities of new instruction sets. This process is tedious, error-prone and requires maintaining multiple code bases. We propose Revec, a compiler optimization pass which revectorizes already vectorized code, by retargeting it to use vector instructions of newer generations. The transformation is transparent, happening at the compiler intermediate representation level, and enables performance portability of hand-vectorized code. Revec can achieve performance improvements in real-world performance critical kernels. In particular, Revec achieves geometric mean speedups of 1.160$\times$ and 1.430$\times$ on fast integer unpacking kernels, and speedups of 1.145$\times$ and 1.195$\times$ on hand-vectorized x265 media codec kernels when retargeting their SSE-series implementations to use AVX2 and AVX-512 vector instructions respectively. We also extensively test Revec's impact on 216 intrinsic-rich implementations of image processing and stencil kernels relative to hand-retargeting.

Είναι γνωστό πως χρησιμοποιούσε δύο σχεδιασμούς για την ανάλυση του. Δηλαδή έναν εσωτερικής διάταξης και έναν εξωτερικής. Στην προσπάθεια μείωσης των σχεδιασμών για την εξοικονόμηση πόρων και χρόνου, άρχισε να χρησιμοποιείται ένας διασταυρούμενος σχεδιασμός (Crossed Array). Με τη βοήθεια της μεθόδου των αποκριτικών επιφανειών και την ανάλυση παλινδρόμησης γίνεται εκτίμηση των επιδράσεων. Παρόλα αυτά το πλήθος των εκτελέσεων είναι μεγάλο και έτσι καταλήγει να είναι δαπανηρό π.χ. για τις βιομηχανίες. Η ανάγκη μείωσης του κόστους οδήγησε σε ανάγκη μείωσης των πειραματικών δοκιμών χωρίς να επηρεαστεί όμως η αξιοπιστία των αποτελεσμάτων. Αρκετοί είναι εκείνοι οι οποίοι πρότειναν να γίνεται χρήση συνδυασμένων σχηματισμών. Οι σχεδιασμοί αυτοί έχουν λιγότερες εκτελέσεις από τους διασταυρούμενους σχεδιασμούς καθώς είναι σαν ένα υποσύνολό τους. Είναι κυρίως μη ισόμορφοι ορθογώνιοι σχεδιασμοί και μας δίνουν τη δυνατότητα να επιλέξουμε τον κατάλληλο αναλόγως το τι επιδράσεις θέλουμε να εκτιμήσουμε. Βάσει του κριτηρίου αποδοτικότητας D – Efficiency γίνεται η επιλογή των βέλτιστων σχεδιασμών από τους χιλιάδες διαθέσιμους αναλόγως το πλήθος των παραγόντων και των πειραματικών δοκιμών. Έτσι επιτυγχάνεται οικονομία χρόνου και ελάττωση του κόστους εκτέλεσης του πειράματος, με τον πειραματιστή να μπορεί να λάβει αξιόπιστες αποφάσεις.

description: We present a quantitative theory, based on crowd effects, for the market volatility in a Minority Game played by a mixed population. Below a critical concentration of generalized strategy players, we find that the volatility in the crowded regime remains above the random coin-toss value regardless of the "temperature" controlling strategy use. Our theory yields good agreement with numerical simulations.

description: Beginning with a continuous wave laser at 1064 nm, we generate a 30 GHz electro-optic frequency comb which contains 100 lines spanning 3 THz. The initial comb is subsequently amplified, spectrally broadened in normal dispersion photonic crystal fiber, and then temporally compressed to provide 74 fs pulses with average power of up to 2.6 W. When launched into a second photonic crystal fiber with anomalous dispersion, a supercontinuum spanning 800-1350 nm is generated. Second harmonic generation allows for extension of the 30 GHz comb into the visible, yielding greater than 300 THz of total spectral bandwidth. Such a broad bandwidth, high repetition rate comb is a compelling source for astronomical spectrograph calibration.
The Host Galaxies of Radio-Loud AGN: The Black Hole--Galaxy Connection

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We have studied the host galaxies of a sample of radio-loud AGN spanning more than four decades in the energy output of the nucleus. The core sample includes 40 low-power sources (BL Lac objects) and 22 high-power sources (radio-loud quasars) spanning the redshift range z~0.15 to z~0.5, all imaged with the high spatial resolution of HST. All of the sources are found to lie in luminous elliptical galaxies, which follow the Kormendy relation for normal ellipticals. A very shallow trend is detected between nuclear brightness (corrected for beaming) and host galaxy luminosity. Black hole masses are estimated for the entire sample, using both the bulge luminosity--black hole mass and the velocity dispersion--black hole mass relations for local galaxies. The latter involves a new method, using the host galaxy morphological parameters, mu_e and r_e, to infer the velocity dispersion, sigma, via the fundamental plane correlation. Both methods indicate that the entire sample of radio-loud AGN are powered by very massive central black holes, with M_{black hole} ~ 10^8 to 10^10 M_{sun}$. Eddington ratios range from L/L_{Eddington} ~ 2 x 10^-4 to ~1, with the high- power sources having higher Eddington ratios than the low-power sources. Overall, radio-loud AGN appear to span a very large range in accretion efficiency, which is all but independent of the mass of the host galaxy.

Charged excitons in doped extended Hubbard model systems

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We show that the charge transfer excitons in a Hubbard model system including nearest neighbor Coulomb interactions effectively attain some charge in doped systems and become visible in photoelectron and inverse photoelectron spectroscopies. This shows that the description of a doped system by an extended Hubbard model differs substantially from that of a simple Hubbard model. Longer range Coulomb interactions cause satellites in the one electron removal and addition spectra and the appearance of spectral weight if the gap of doped systems at energies corresponding to the excitons of the undoped systems. The spectral weight of the satellites is proportional to the doping times the coordination number and therefore is strongly dependent on the dimension.

description: Caluromysiops irrupta Sanborn, 1951
TYPE MATERIAL AND TYPE LOCALITY: FMNH 68336, the holotype by original designation, consists of the skin and skull of a juvenile male collected at Quincemil (13.22° S, 70.70° W; 680 m), Cusco department, Peru.
SYNONYMS: None.
 DISTRIBUTION: Caluromysiops irrupta is restricted to lowland Amazonia, where it is known from scattered localities in Brazil (Mato Grosso, Rondônia), Colombia (Amazonas), and Peru (Loreto, Madre de Dios) (Santori et al., 2016: fig. 2).
 REMARKS: See Voss and Jansa (2009) for illustrations, analyses of phylogenetic relationships and qualitative morphological descriptors. The only published morphometric data for Caluromysiops irrupta are still those in Izor and Pine (1987). Despite several reported sightings and one recent capture (summarized by Santori et al., 2016), no new morphological specimens or genetic samples have been obtained for several decades.

Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Newtonian Cosmology is commonly used in astrophysical problems, because of its obvious simplicity when compared with general relativity. However it has inherent difficulties, the most obvious of which is the non-existence of a well-posed initial value problem. In this paper we investigate how far these problems are met by using the post-Newtonian approximation in cosmology.

description: A Darboux-type method of solving the nonlinear von Neumann equation $i\dot ρ=[H,f(ρ)]$, with functions $f(ρ)$ commuting with $ρ$, is developed. The technique is based on a representation of the nonlinear equation by a compatibility condition for an overdetermined linear system. von Neumann equations with various nonlinearities $f(ρ)$ are found to possess the so-called self-scattering solutions. To illustrate the result we consider the Hamiltonian $H$ of a one-dimensional harmonic oscillator and $f(ρ)=ρ^q-2ρ^{q-1}$ with arbitary real $q$. It is shown that self-scattering solutions possess the same asymptotics for all $q$ and that different nonlinearities may lead to effectively indistinguishable evolutions. The result may have implications for nonextensive statistics and experimental tests of linearity of quantum mechanics.

Dependence of DNA persistence length on ionic strength and ion type

description: Even though the persistence length $L_P$ of double-stranded DNA plays a pivotal role in cell biology and nanotechnologies, its dependence on ionic strength $I$ lacks a consensual description. Using a high-throughput single-molecule technique and statistical physics modeling, we measure $L_P$ in presence of monovalent (Li$^+$, Na$^+$, K$^+$) and divalent (Mg$^{2+}$, Ca$^{2+}$) metallic and alkyl ammonium ions, over a large range 0.5 mM $\leq I\leq 5$ M. We show that linear Debye-Hückel-type theories do not describe even part of these data. By contrast, the Netz-Orland and Trizac-Shen formulas, two approximate theories including non-linear electrostatic effects and the finite DNA radius, fit our data with divalent and monovalent ions, respectively, over the whole $I$ range. Furthermore the metallic ion type does not influence $L_P(I)$, in contrast to alkyl ammonium monovalent ions at high $I$.

By summing infinite series of diagrams, we derive a complex free energy whose imaginary part is related to the relaxation time of the system. Summation of another series yields two--point correlation function whose correlation length is essentially given by the Jeans wavelength of the system.

Interpolating self-energy of the infinite-dimensional Hubbard model: Modifying the iterative perturbation theory

Year: 1997

description: We develop an analytical expression for the self-energy of the infinite-dimensional Hubbard model that is correct in a number of different limits. The approach represents a generalization of the iterative perturbation theory to arbitrary fillings. In the weak-coupling regime perturbation theory to second order in the interaction U is recovered. The theory is exact in the atomic limit. The high-energy behavior of the self-energy up to order (1/E)**2 and thereby the first four moments of the spectral density are reproduced correctly. Referring to a standard strong-coupling moment method, we analyze the limit of strong U. Different modifications of the approach are discussed and tested by comparing with the results of an exact diagonalization study.

description: We present an evaluation of the two master integrals for the crossed vertex diagram with a closed loop of top quarks that allows for an easy numerical implementation. The differential equations obeyed by the master integrals are used to generate power series expansions centered around all the singular points. The different series are then matched numerically with high accuracy in intermediate points. The expansions allow a fast and precise numerical calculation of the two master integrals in all the regions of the phase space. A numerical routine that implements these expansions is presented.

description: It is argued that the ambiguity introduced by the renormalization in the effective action of a four-dimensional renormalizable quantum field theory is at most a local polynomial action of canonical dimension four. The allowed ambiguity in the expected stress-energy tensor of a massive scalar field is severely restricted by this fact.

X-ray and gamma-ray spectra and variability of the black-hole candidate GX 339-4

description: We analyse five observations of the X-ray binary GX 339-4 by the soft gamma-ray OSSE detector on board CGRO simultaneous with either Ginga or RXTE observations. The source was bright during four of them, with the luminosity of L ~ 10^{37} erg/s and the spectrum typical for hard states of accreting black holes, and it was in an off state during the fifth one, with L ~ 10^{35} erg/s. Our broad-band spectral fits show the mean electron energy of electrons in the Comptonizing plasma decreasing with increasing luminosity within the hard (bright) state. For the observation with the best statistics at soft gamma-rays, approximately 1/4 of energy in the Comptonizing plasma is probably carried by non-thermal electrons. Then, considering the efficiency of Comptonized hybrid synchrotron emission allows us to obtain an upper limit on the strength of the magnetic field in the X-ray source. Furthermore, this synchrotron emission is capable of producing the optical spectrum observed in an optically-high state of GX 339-4. In the off state, the hard X-ray spectrum is consistent with being dominated by bremsstrahlung. The unusually strong Fe K alpha line observed by the PCA during that state is found not to be intrinsic to the source but to originate mostly in the Galactic diffuse emission.
