description: Industries in the area of oil and gas need reliable source of information to take their strategic decisions. One of these sources is called “Documentation of Well”, a dossier which gathers information about the wells, since the stage of the location until its conclusion. The organization and availability of information in the “Documentation of Well” ensure more flexibility in its use, then many companies used to invest in good information systems, and in techniques of data organization. Petrobras, for example, makes use of taxonomies applied to their structures “Documentation of Well” in a joint effort of multidisciplinary teams of the technical area of the business, documentation and information systems. Thus, this work develops a review of the literature about sources of information in the area of oil and gas, in the context of the documentation of the well as such, and displays an expertise in the area of Well Engineering of Petrobras.
Anisotropic Cosmological Constant and the CMB Quadrupole Anomaly

description: There are evidences that the cosmic microwave background (CMB) large-angle anomalies imply a departure from statistical isotropy and hence from the standard cosmological model. We propose a LCDM model extension whose dark energy component preserves its nondynamical character but wield anisotropic vacuum pressure. Exact solutions for the cosmological scale factors are presented, upper bounds for the deformation parameter are evaluated and its value is estimated considering the elliptical universe proposal to solve the quadrupole anomaly. This model can be constructed from a Bianchi I cosmology with cosmological constant from two different ways: i) a straightforward anisotropic modification of the vacuum pressure consistently with energy-momentum conservation; ii) a Poisson structure deformation between canonical momenta such that the dynamics remain invariant under scale factors rescalings.

description: The topology of closed manifolds forces interacting charges to appear in pairs. We take advantage of this property in the setting of the conformal boundary of $\mathrm{AdS}_5$ spacetime, topologically equivalent to the closed manifold $S^1\times S^3$, by considering the coupling of two massless opposite charges on it. Taking the interaction potential as the analog of Coulomb interaction (derived from a fundamental solution of the $S^3$ Laplace-Beltrami operator), a conformal $S^1\times S^3$ metric deformation is proposed, such that free motion on the deformed metric is equivalent to motion on the round metric in the presence of the interaction potential. We give explicit expressions for the generators of the conformal algebra in the representation induced by the metric deformation. By identifying the charge as the color degree of freedom in QCD, and the two charges system as a quark--anti-quark system, we argue that the associated conformal wave operator equation could provide a realistic quantum mechanical description of the simplest QCD system, the mesons. Finally, we discuss the possibility of employing the compactification radius, $R$, as another scale along $Λ_{QCD}$, by means of which, upon reparametrizing $Q^2c^2$ as $\left( Q^2c^2 +\hbar^2 c^2/R^2\right)$, a pertubative treatment of processes in the infrared could be approached.

A VLSI System-on-Chip for Particle Detectors
Creators: name: Giordano, Raffaele
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: In this thesis I present a System-on-Chip (SoC) I designed to offer a self-contained, compact data acquisition platform for micromegas detector monitoring. I carried on my work within the RD-51 collaboration of CERN. With a companion ADC, my architecture is capable to acquire the signal from a detector electrode, process the data and perform monitoring tests. The SoC is built around on a custom 8-bit microprocessor with internal memory resources and embeds the peripherals to be interfaced with the external ADC. Peripherals implement in hardware threshold checking, pedestal suppression, waveform recording and histogram building. The CPU has some attractive features for real-time applications: high working frequency, constant instruction execution time, short and fixed interrupt latency and a tiny logic footprint. The processor makes it possible to execute in software additional off-line data processing, such as averaging, FWHM calculation and peak finding. It includes an 8-bit IO bus for interfacing with external logic and a UART for RS232 communications. The architecture is fully portable to any technology for the implementation of digital circuits (e.g. VLSI CMOS or FPGAs). In fact, I implemented and tested a prototype in a Virtex-II Xilinx FPGA and I completed the layout of a standard-cell CMOS 90nm version of system. The performance in terms of clock frequency and logic resource occupation are discussed in the view of the deployment of the system with the detector and of the development of a multi-channel version of the system.
title:  Smart contract e ‘giusto rimedio civile’ del re-coding tra Rule by Design e Rule of Law

description: The essay emphasizes the responsible role that the jurist is called to play in order to interpret and integrate – in the presence of a smart legal contract – the output of the machine (so-called ‘computer effect’ or ‘code-result’ or ‘fruit contract ex machina’). Hence the opportunity to adopt, as in the Maltese legal system happens, a so-called “hybrid” intelligent agreement model, i.e. focused on the mixture of computer and human language, which shows undoubted advantages in asymmetric agreements (B2C). In another respect, in cases of non-compliance of the smart contract with our legal system, the ‘proper civil remedy’ (atypical) of ‘re-coding’ moves in the direction of ‘re-writing’ the algorithm so as to make the Lex Criptographi(c)a immune to appreciable defects in an eminently legal point of view.

The coalescence of invariant manifolds and the spiral structure of barred galaxies

description: In a previous paper (Voglis et al. 2006a, paper I) we demonstrated that, in a rotating galaxy with a strong bar, the unstable asymptotic manifolds of the short period family of unstable periodic orbits around the Lagrangian points L$_1$ or L$_2$ create correlations among the apocentric positions of many chaotic orbits, thus supporting a {\it spiral} structure beyond the bar. In the present paper we present evidence that the unstable manifolds of {\it all} the families of unstable periodic orbits near and beyond corotation contribute to the same phenomenon. Our results refer to a N-Body simulation, a number of drawbacks of which, as well as the reasons why these do not significantly affect the main results, are discussed. We explain the dynamical importance of the invariant manifolds as due to the fact that they produce a phenomenon of `stickiness' slowing down the rate of chaotic escape in an otherwise non-compact region of the phase space. We find a stickiness time of order 100 dynamical periods, which is sufficient to support a long-living spiral structure. Manifolds of different families become important at different ranges of values of the Jacobi constant. The projections of the manifolds of all the different families in the configuration space produce a pattern due to the `coalescence' of the invariant manifolds. This follows closely the maxima of the observed $m=2$ component near and beyond corotation. Thus, the manifolds support both the outer edge of the bar and the spiral arms.

The residual word-finding deficit of traumatically head-injured children
Creators: name: Hvozdanski, Marion Jeanette
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to investigate the nature of the residual word-finding deficit after severe head-injury. Reach of five severely head—injured subjects, (2;0-8;0 post-injury) males, ranging in age from 10;0—17;0 was compared with a Control matched for age and sex. Subjects were tested with a number of standardized and experimental language tests. Results were compared between subject groups. Results indicated that naming stimulus and condition affected the accuracy of the head—injured childrens' responses. Photographs were easier to name than line drawings. Visual confrontation naming and sentence completion were easier tasks than naming to auditory description, which in turn was easier than naming to palpation. Metalinguistic skills, e.g. antonyms and homonyms, were demonstrated to be an area of deficit for the head-injured children and warrant further research. Expository speech of the head-injured children was marked by an overall simplifications smaller MLU, and reduction of syntactic complexity when compared with the Control group. The speech of the head-injured children also contained more pauses which are indicative of word-finding difficulty.

description: The infrared behavior of the quark propagator is studied at one loop and in the Landau gauge ($ξ=0$) using the screened massive expansion of full QCD and three different resummation schemes for the quark self-energy. The shift of the expansion point of perturbation theory, which defines the screened expansion, together with a non-standard renormalization of the bare parameters, proves sufficient to describe the dynamical generation of an infrared quark mass also in the chiral limit. Analytically, the scale for such a mass is set by a mass parameter $M$, whose value is fixed by a fit to the lattice data for quenched QCD. The quark mass function $\mathcal{M}(p^{2})$ is shown to be in very good agreement with the lattice results. The quark $Z$-function, on the other hand, shows the wrong qualitative behavior in all but one of the studied resummation schemes, where its behavior is qualitatively correct, but only at sufficiently high energies.

description: In this work, we review the effective field theory framework to search for Lorentz and CPT symmetry breaking during the propagation of gravitational waves. The article is written so as to bridge the gap between the theory of spacetime-symmetry breaking and the analysis of gravitational-waves signals detected by ground-based interferometers. The primary physical effects beyond General Relativity that we explore here are dispersion and birefringence of gravitational waves. We discuss their implementation in the open-source LIGO-Virgo algorithm library suite, as well as the statistical method used to perform a Bayesian inference of the posterior probability of the coefficients for symmetry-breaking. We present preliminary results of this work in the form of simulations of modified gravitational waveforms, together with sensitivity studies of the measurements of the coefficients for Lorentz and CPT violation. The findings show the high potential of gravitational wave sources across the sky to probe sensitively for these signals of new physics.

Some partial results are obtained in the remaining cases: in particular we give examples of leading-order solutions with singular isolated "ergocircles".

Year: 2006

description: In according to the importance of meat in the diet and of its diffuse use in Western Countries, it’s necessary to give attention to a particular nutritional aspect of meat, concerning food safety, which is one of the most important goals in food science nowadays.
It is well know that PUFA fatty acid and iron are among main factors improving lipid oxidation, so their reduction by animal diet may be an efficacy mean to improve oxidative stability in meat. However, this  measure may not be acceptable in practice because PUFA and iron are both nutritional elements for human health.
This research work has begun from studying of antioxidant to prevent lipid oxidation until arriving to find a model to induce oxidation to investigate the process in vitro.
Work plan can be schedules in three parts:
Part 1: protective effects of natural antioxidants against peroxidation during cooking and storage
Part 2: Determination of MDA and TBARs in Buffalo Meat from Animals with dietary supplementation of Vitamin E
Part 3: Development of analytical procedures to study changes in the lipid composition of meat caused by induced oxidation.

description: La ricerca riguarda la formazione e la trasformazione nel tempo di un’ampia porzione della città di Napoli, tradizionalmente trascurata dagli studi anche perché entrata a far parte dell’area municipale a partire dal 1927. Si tratta dei territori degli antichi comuni di Chiaiano ed Uniti,  Pianura, Soccavo, Marianella e Miano (questi ultimi solo per i versanti collinari). Sono state analizzate le fonti letterarie, le numerose descrizioni di viaggi, e il materiale cartografico e iconografico, quest’ultimo in gran parte inedito. Si articola in tre volumi: il primo di testo, il secondo di appendice documentaria, il terzo di illustrazioni e materiali cartografici. Il primo è diviso in due parti: una relativa all’analisi dei caratteri originari del territorio studiato e alla “fortuna” del paesaggio collinare napoletano attraverso i Piani Regolatori fino alla creazione del Parco Metropolitano delle Colline di Napoli, e una seconda dove sono analizzate le fonti scritte e cartografiche per delineare la storia del territorio e quella delle emergenze architettoniche, dando particolare rilievo alle carte manoscritte di G.B. Porpora. Nuove e importanti acquisizioni documentarie riguardano ville dello Scudillo e del Moiariello, una importante masseria della famiglia Caracciolo a Chiamano, le cave di tufo dalla fine dell’800 agli anni Settanta del ‘900 e l’uso delle aree boschive di Marano, Chiaiano, Marianella, Capodimonte, Pianura, Soccavo, nella prima metà dell’800. E’ stato così possibile ricostruire la vicenda storica del territorio studiato.

description: Methylene blue (MB) is often used in textile industries and is actively present in the wastewater runs-off. Recently, mediated electrochemical oxidation (MEO) offers a fast, reliable and promising results for environmental remediation. Thus, we aimed to evaluate the electro-degradation potential of MB by MEO using Ce(IV) ionic mediator. Furthermore, we also observed the influence of addition Ag(I) ion catalyst in MEO for degradation of MB. The electro-degradation of MB was evaluated by cyclic voltammetry technique and was confirmed by UV-Vis spectrophotometry, high performance liquid chromatography (HPLC) analysis and back-titration analysis. The results showed that in the absence of Ag(I) ion catalyst, about 89 % of MB was decolorized within 30 minutes. When 2 mM of Ag(I) ion catalyst was applied, the electro-degradation of MB was increased to maximum value of 100%. The UV-Vis spectrum confirmed the electro-degradation of MB as suggested by decreased maximum absorbance value at λ 668 nm from 2.125 to 0.059. The HPLC analysis showed the formation of five new peaks at retention time of 1.331, 1.495, 1.757, 1.908 and 2.017 minutes, confirming the electro-degradation of MB. The back-titration analysis showed about 52.9% of CO2 was produced during electro-degradation of MB by MEO. More importantly, more than 97% of Ce(IV) ionic mediator were recovered in our investigation. Our results reveal the potential of MEO using Ce(IV) ionic mediator to improve the wastewater runs-off quality from textile as well as other industries containing methylene blue.

description: A procedure that allows to obtain the dynamics of $N$ independent bodies each locally interacting with its own reservoir is presented. It relies on the knowledge of single body dynamics and it is valid for any form of environment noise. It is then applied to the study of non-Markovian dynamics of two independent qubits, each locally interacting with a zero temperature reservoir. It is shown that, although no interaction is present or mediated between the qubits, there is a revival of their entanglement, after a finite period of time of its complete disappearance.

Year: 2021
Subjects: pre-treatment verification, rotating phantom setup

description: Abstract Purpose: To check the setup position of the Octavius phantom in pre-treatment verification of VMAT radiotherapy plans and to reduce the influence of the setup error on gamma analysis. Methods: The gamma index measures the difference between the computed dose distribution by the treatment planning system and the dose distribution obtained with the QA device in pre-treatment plan verification. The gamma index is affected by several factors. One of these is the rotating phantom setup position error. To estimate the later in complex dose distributions, instead of ‘Align Automatically’ function implemented in Verisoft program, our method is presented. We carry out the determination of the phantom shift before the treatment plan verification. It based on obtaining dose distributions an anterior-posterior and a lateral square field. The phantom's shift is obtained by comparing theirs position with orthogonal fields being in exact position. After performing the pre-treatment verification measurement of the actual RT plan, the 3D dose matrix generated by the Verisoft program is shifted to opposite directions with the obtained shifts. After them, the gamma analysis is performed. The phantom setup error correction method was tested with 10 head and neck simultan- integrated boost and additional boost and 10 prostate ones with boost. Results Significant increase in gamma index was given after setup error correction especially when 2mm distance and 2% dose criteria was used, while we experienced low variation in gamma index with 3mm distance and 3% dose criteria. Conclusion The presented method allows the user to check and correct the rotating phantom’s setup error within 0.5-2mm range.

description: Single crystals of the dilute, rare earth bearing, pseudo-ternary series, Gd_xY_{1-x}Fe_2Zn_{20} were grown out of Zn-rich solution. Measurements of magnetization, resistivity and heat capacity on Gd_xY_{1-x}Fe_2Zn_{20} samples reveal ferromagnetic order of Gd^{3+} local moments across virtually the whole series ($x \geq 0.02$). The magnetic properties of this series, including the ferromagnetic ordering, the reduced saturated moments at base temperature, the deviation of the susceptibilities from Curie-Weiss law and the anomalies in the resistivity, are understood within the frame work of dilute, $\textbf {S}$ moments (Gd^{3+}) embedded in a nearly ferromagnetic Fermi liquid (YFe_2Zn_{20}). The s-d model is employed to further explain the variation of $T_{\mathrm{C}}$ with x as well as the temperature dependences of of the susceptibilities.
The Representation of Purgatory in a Colonial Painting from Latin America
Creators: name: Vásquez, Rafael Alas
Publisher: name: Digital Repository at the University of Maryland
Year: 1990

description: The representation of purgatory in painting was very
popular after the Council of Trent. While Protestant
denied the existence of purgatory, the Catholic Church,
with the help of religious orders and brotherhoods,
fostered the devotion to the suffering souls. During
the colonial period in Latin America, this devotion
gained a unique importance. This fact is reflected in
the numerous paintings representing purgatory that are
displayed in cathedrals and churches.
The purpose of this thesis is to study the
iconography of one of these paintings representing
purgatory. The chosen painting presents different
figures of souls among the flames. The Virgin del
Carmen is represented holding one soul, while the
figures of St. Peter and St. Michael are looking toward
heaven. A Crucifix and the Holy Ghost appear above the
figure of the Virgin.
The representation in purgatory of a bishop, a nun
and a Black man, besides the depiction of souls at
different ages show the Catholic belief that every
sinner has to pass through purgatory. Two unusual
motifs are the depiction of st. Peter in purgatory and
the representation of the Virgin pulling a soul from
the flames. The painting reflects the concept of
purgatory that the Catholic Church spread after the
Council of Trent. The effectiveness of masses to help
the souls, symbolized by the depiction of Christ on the
Cross, and the intervention of Mary to release souls
from purgatory are two important messages that this
painting is presenting to the worshiper.

description: The success of supervised classification of remotely sensed images acquired over large geographical areas or at short time intervals strongly depends on the representativity of the samples used to train the classification algorithm and to define the model. When training samples are collected from an image (or a spatial region) different from the one used for mapping, spectral shifts between the two distributions are likely to make the model fail. Such shifts are generally due to differences in acquisition and atmospheric conditions or to changes in the nature of the object observed. In order to design classification methods that are robust to data-set shifts, recent remote sensing literature has considered solutions based on domain adaptation (DA) approaches. Inspired by machine learning literature, several DA methods have been proposed to solve specific problems in remote sensing data classification. This paper provides a critical review of the recent advances in DA for remote sensing and presents an overview of methods divided into four categories: i) invariant feature selection; ii) representation matching; iii) adaptation of classifiers and iv) selective sampling. We provide an overview of recent methodologies, as well as examples of application of the considered techniques to real remote sensing images characterized by very high spatial and spectral resolution. Finally, we propose guidelines to the selection of the method to use in real application scenarios.

description: We consider a $G$-function $F(z)=\sum_{k=0}^{\infty} A_k z^k \in \mathbb{K}[[z]]$, where $\mathbb{K}$ is a number field, of radius of convergence $R$ and annihilated by the $G$-operator $L \in \mathbb{K}(z)[\mathrm{d}/\mathrm{d}z]$, and a parameter $β\in \mathbb{Q} \setminus \mathbb{Z}_{\leqslant 0}$. We define a family of $G$-functions $F_{β,n}^{[s]}(z)=\sum_{k=0}^{\infty} \frac{A_k}{(k+β+n)^s} z^{k+n}$ indexed by the integers $s$ and $n$. Fix $α\in \mathbb{K}^* \cap D(0,R)$. Let $Φ_{α,β,S}$ be the $\mathbb{K}$-vector space generated by the values $F_{β,n}^{[s]}(α)$, $n \in \mathbb{N}$, $0 \leqslant s \leqslant S$. We show that there exist some positive constants $u_{\mathbb{K},F,β}$ and $v_{F,β}$ such that $u_{\mathbb{K},F,β} \log(S) \leqslant \dim_{\mathbb{K}} Φ_{α,β,S} \leqslant v_{F,β} S$. This generalizes a previous theorem of Fischler and Rivoal (2017), which is the case $β=0$. Our proof is an adaptation of their article "Linear independence of values of $G$-functions'' ([FR]), making use of the André-Chudnovsky-Katz Theorem on the structure of the $G$-operators and of the saddle point method.

description: We derive four-dimensional (4D) effective theories of the gauge-Higgs unification models in the warped spacetime. The effective action can be expressed in a simple form by neglecting subleading corrections to the wave functions. We have shown in our previous works that some Higgs couplings to the other fields are suppressed by factors that depend on $\barθ_H$ from the values in the standard model. Here $\barθ_H$ is the Wilson line phase along the fifth dimension, which characterizes the electroweak symmetry breaking. The effective action derived here explicitly shows a nonlinear structure of the Higgs sector, which clarifies the origins of those suppression factors.

Emergent diffeomorphism invariance in a discrete loop quantum gravity model

Year: 2008
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Several approaches to the dynamics of loop quantum gravity involve discretizing the equations of motion. The resulting discrete theories are known to be problematic since the first class algebra of constraints of the continuum theory becomes second class upon discretization. If one treats the second class constraints properly, the resulting theories have very different dynamics and number of degrees of freedom than those of the continuum theory. It is therefore questionable how these theories could be considered a starting point for quantization and the definition of a continuum theory through a continuum limit. We show explicitly in a model that the {\em uniform discretizations} approach to the quantization of constrained systems overcomes these difficulties. We consider here a simple diffeomorphism invariant one dimensional model and complete the quantization using {\em uniform discretizations}. The model can be viewed as a spherically symmetric reduction of the well known Husain--Kuchař model of diffeomorphism invariant theory. We show that the correct quantum continuum limit can be satisfactorily constructed for this model. This opens the possibility of treating 1+1 dimensional dynamical situations of great interest in quantum gravity taking into account the full dynamics of the theory and preserving the space-time covariance at a quantum level.

description: We use SPITZER IRAC 3.6 and 4.5micron near infrared data from the Spitzer Infrared Nearby Galaxies Survey (SINGS), optical B, V and I and 2MASS Ks band data to produce mass surface density maps of M81. The IRAC 3.6 and 4.5micron data, whilst dominated by emission from old stellar populations, is corrected for small-scale contamination by young stars and PAH emission. The I band data are used to produce a mass surface density map by a B-V colour-correction, following the method of Bell and de Jong. We fit a bulge and exponential disc to each mass map, and subtract these components to reveal the non-axisymmetric mass surface density. From the residual mass maps we are able to extract the amplitude and phase of the density wave, using azimuthal profiles. The response of the gas is observed via dust emission in the 8micron IRAC band, allowing a comparison between the phase of the stellar density wave and gas shock. The relationship between this angular offset and radius suggests that the spiral structure is reasonably long lived and allows the position of corotation to be determined.

Phylogenetic analysis of the North American species of Telorchis luehe, 1899 (Cercomeria:Digenea:Telorchiidae)
Creators: name: Macdonald, Cheryl Ann
Publisher: name: University of British Columbia
Year: 2010

description: Telorchiids are plagiorchiform intestinal parasites inhabiting turtles, and occasionally snakes and salamanders. Previous taxonomic revisions of the group have been problematical due to a lack of information on intraspecific morphological variation. In the present study, ten of the thirty described North American species are considered valid. Phylogenetic analysis of 22 character states comprising 20 homologous series results in a single phylogenetic tree with a consistency index of 95%. Only one of the characters used in the analysis is homoplasious. In order to maintain a classification that reflects the phylogeny of the group, only one of four proposed genera is recognized. A biogeographical analysis is not feasible due to incomplete collecting records. The two most relatively plesiomorphic telorchiid species are found in salamanders. Five of the eight species from amniotes are considered to have co-speciated with their hosts. One of the secondarily evolved species is postulated to have evolved via a host-switch from turtles to snakes. The other two secondarily evolved species appear to have arisen via sympatric speciation, facilitated by mechanical pre-mating isolation due to a difference in genital pore position. As primarily coevolved telorchiids become more highly derived there is an increase in host specificity, which is consistent with the traditional view of host-parasite relationships.

description: Abstract

Solitary fibrous tumor (formerly hemangiopericytoma) is a rare, aggressive and highly metastatic tumor of the soft tissues and meninges. The majority of metastases occur in bone, lung and liver, and rarely in other organs. Pancreatic metastases are extremely rare. We report here a rare case of recurrent meningeal solitary fibrous tumor with pancreatic metastases in a woman who had a surgical resection 18 years earlier, and describe the CT and MRI imaging features.

description: The spectrum of triatomic molecules with close rovibrational opposite parity levels is sensitive to the $\mathcal{P}$,$\mathcal{T}$-odd effects. This makes them a convenient platform for the experimental search of a new physics. Among the promising candidates one may distinguish the YbOH as a non-radioactive compound with a heavy atom. The energy gap between levels of opposite parity, $l$-doubling, is of a great interest as it determines the electric field strength required for the full polarization of the molecule. Likewise, the influence of the bending and stretching modes on the sensitivities to the $\mathcal{P}$,$\mathcal{T}$-violation requires a thorough investigation since the measurement would be performed on the excited vibrational states. This motivates us to obtain the rovibrational nuclear wavefunctions, taking into account the anharmonicity of the potential. As a result, we get the values of the $E_{\rm eff}$ and $E_s$ for the lowest excited vibrational state and determine the $l$-doubling

description: High $p_T$ single and dihadron production is studied within a NLO pQCD parton model with jet quenching in high energy $A+A$ collisions at the RHIC/LHC energy. A simultaneous $χ^2$-fit to both single and dihadron spectra can be achieved within a narrow range of energy loss parameter. Punch-through jets are found to result in the dihadron suppression factor slightly more sensitive to medium than the single hadron suppression factor at RHIC. Such jets at LHC are found to dominate high $p_T$ dihadron production and the resulting dihadron spectra are more sensitive to the initial parton distribution functions than the single hadron spectra.

description: We present 0\farcs{14}-resolution Atacama Large Millimeter/submillimeter Array (ALMA) CO(2$-$1) observations of the circumnuclear gas disk in UGC 2698, a local compact galaxy. The disk exhibits regular rotation with projected velocities rising to 450 km s$^{-1}$ near the galaxy center. We fit gas-dynamical models to the ALMA data cube, assuming the CO emission originates from a dynamically cold, thin disk, and measured the mass of the supermassive black hole (BH) in UGC 2698 to be $M_{\mathrm{BH}} = (2.46 \pm{0.07}$ [$1σ$ stat] $^{+0.70}_{-0.78}$ [sys])$\times 10^9$ $M_\odot$. UGC 2698 is part of a sample of nearby early-type galaxies that are plausible $z\sim2$ red nugget relics. Previous stellar-dynamical modeling for three galaxies in the sample found BH masses consistent with the BH mass$-$stellar velocity dispersion ($M_{\mathrm{BH}}-σ_\star$) relation but over-massive relative to the BH mass$-$bulge luminosity ($M_{\mathrm{BH}}-L_{\mathrm{bul}}$) correlation, suggesting that BHs may gain the majority of their mass before their host galaxies. However, UGC 2698 is consistent with both $M_{\mathrm{BH}}-σ_\star$ and $M_{\mathrm{BH}}-L_{\mathrm{bul}}$. As UGC 2698 has the largest stellar mass and effective radius in the local compact galaxy sample, it may have undergone more recent mergers that brought it in line with the BH scaling relations. Alternatively, given that the three previously-measured compact galaxies are outliers from $M_{\mathrm{BH}}-L_{\mathrm{bul}}$, while UGC 2698 is not, there may be significant scatter at the poorly sampled high-mass end of the relation. Additional gas-dynamical $M_{\mathrm{BH}}$ measurements for the compact galaxy sample will improve our understanding of BH$-$galaxy co-evolution.

description: Knowledge graph completion (KGC) has become a focus of attention across deep learning community owing to its excellent contribution to numerous downstream tasks. Although recently have witnessed a surge of work on KGC, they are still insufficient to accurately capture complex relations, since they adopt the single and static representations. In this work, we propose a novel Disentangled Knowledge Graph Attention Network (DisenKGAT) for KGC, which leverages both micro-disentanglement and macro-disentanglement to exploit representations behind Knowledge graphs (KGs). To achieve micro-disentanglement, we put forward a novel relation-aware aggregation to learn diverse component representation. For macro-disentanglement, we leverage mutual information as a regularization to enhance independence. With the assistance of disentanglement, our model is able to generate adaptive representations in terms of the given scenario. Besides, our work has strong robustness and flexibility to adapt to various score functions. Extensive experiments on public benchmark datasets have been conducted to validate the superiority of DisenKGAT over existing methods in terms of both accuracy and explainability.

description: Coupled backward and forward wave amplitudes of an electromagnetic field propagating in a periodic and nonlinear medium at Bragg resonance are governed by the nonlinear coupled mode equations (NLCME). This system of PDEs, similar in structure to the Dirac equations, has gap soliton solutions that travel at any speed between 0 and the speed of light. A recently considered strategy for spatial trapping or capture of gap optical soliton light pulses is based on the appropriate design of localized defects in the periodic structure. Localized defects in the periodic structure give rise to defect modes, which persist as {\it nonlinear defect modes} as the amplitude is increased. Soliton trapping is the transfer of incoming soliton energy to {\it nonlinear} defect modes. To serve as targets for such energy transfer, nonlinear defect modes must be stable. We therefore investigate the stability of nonlinear defect modes. Resonance among discrete localized modes and radiation modes plays a role in the mechanism for stability and instability, in a manner analogous to the nonlinear Schrödinger / Gross-Pitaevskii (NLS/GP) equation. However, the nature of instabilities and how energy is exchanged among modes is considerably more complicated than for NLS/GP due, in part, to a continuous spectrum of radiation modes which is unbounded above and below. In this paper we (a) establish the instability of branches of nonlinear defect states which, for vanishing amplitude, have a linearization with eigenvalue embedded within the continuous spectrum, (b) numerically compute, using Evans function, the linearized spectrum of nonlinear defect states of an interesting multiparameter family of defects, and (c) perform direct time-dependent numerical simulations in which we observe the exchange of energy among discrete and continuum modes.

description: We consider the genus of 20 classes of unimodular Hermitian lattices of rank 12 over the Eisenstein integers. This set is the domain for a certain space of algebraic modular forms. We find a basis of Hecke eigenforms, and guess global Arthur parameters for the associated automorphic representations, which recover the computed Hecke eigenvalues. Congruences between Hecke eigenspaces, combined with the assumed parameters, recover known congruences for classical modular forms, and support new instances of conjectured Eisenstein congruences for U(2,2) automorphic forms.
