Sequence Length is a Domain: Length-based Overfitting in Transformer Models

description: Transformer-based sequence-to-sequence architectures, while achieving state-of-the-art results on a large number of NLP tasks, can still suffer from overfitting during training. In practice, this is usually countered either by applying regularization methods (e.g. dropout, L2-regularization) or by providing huge amounts of training data. Additionally, Transformer and other architectures are known to struggle when generating very long sequences. For example, in machine translation, the neural-based systems perform worse on very long sequences when compared to the preceding phrase-based translation approaches (Koehn and Knowles, 2017). We present results which suggest that the issue might also be in the mismatch between the length distributions of the training and validation data combined with the aforementioned tendency of the neural networks to overfit to the training data. We demonstrate on a simple string editing task and a machine translation task that the Transformer model performance drops significantly when facing sequences of length diverging from the length distribution in the training data. Additionally, we show that the observed drop in performance is due to the hypothesis length corresponding to the lengths seen by the model during training rather than the length of the input sequence.

description: We investigate the spectral statistics of chaotic quasi one dimensional systems such as long wires. To do so we represent the spectral correlation function $R(ε)$ through derivatives of a generating function and semiclassically approximate the latter in terms of periodic orbits. In contrast to previous work we obtain both non-oscillatory and oscillatory contributions to the correlation function. Both types of contributions are evaluated to leading order in $1/ε$ for systems with and without time-reversal invariance. Our results agree with expressions from the theory of disordered systems.

description: We study the properties and production mechanisms of color-octet scalars at the LHC. We focus on the single production of both charged and neutral members of an (8,2)_1/2 doublet through bottom quark initial states. These channels provide a window to the underlying Yukawa structure of the scalar sector. Color-octet scalars naturally appear in grand unified theories based on the SU(5) gauge symmetry. In the context of adjoint SU(5) these fields are expected to be light to satisfy constraints coming from unification and proton decay, and may have TeV-scale masses. One combination of their couplings is defined by the relation between the down-quark and charged-lepton Yukawa couplings. Observation of these states at the LHC gives an upper bound on the proton lifetime if they truly arise from this grand unified theory. We demonstrate that TeV-mass scalars can be observed over background at the LHC using boosted top quark final states, and study how well the scalar Yukawa parameters can be measured.

description: We propose a two-stage multi-objective optimization framework for full scheme solar cell structure design and characterization, cost minimization and quantum efficiency maximization. We evaluated structures of 15 different cell designs simulated by varying material types and photodiode doping strategies. At first, non-dominated sorting genetic algorithm~II (NSGA-II) produced Pareto-optimal-solutions sets for respective cell designs. Then, on investigating quantum efficiencies of all cell designs produced by NSGA-II, we applied a new multi-objective optimization algorithm~II (OptIA-II) to discover the Pareto fronts of select (three) best cell designs. Our designed OptIA-II algorithm improved the quantum efficiencies of all select cell designs and reduced their fabrication costs. We observed that the cell design comprising an optimally doped zinc-oxide-based transparent conductive oxide (TCO) layer and rough silver back reflector (BR) offered a quantum efficiency ($Q_e$) of $0.6031.$ Overall, this paper provides a full characterization of cell structure designs. It derives a relationship between quantum efficiency, $Q_e$ of a cell with its TCO layer's doping methods and TCO and BR layer's material types. Our solar cells design characterization enables us to perform a cost-benefit analysis of solar cells usage in real-world applications

description: We report polarized neutron scattering and piezoresponse force microscopy studies of millimeter-sized single crystals of multiferroic BiFeO$_3$. The crystals, grown below the Curie temperature, consist of a single ferroelectric domain. Two unique electric polarization directions, as well as the populations of equivalent spiral magnetic domains, can be switched reversibly by an electric field. A ferroelectric monodomain with a single-$q$ single-helicity spin spiral can be obtained. This level of control, so far unachievable in thin films, makes single-crystal BiFeO$_3$ a promising object for multiferroics research.

Drone swarm patrolling with uneven coverage requirements

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Swarms of drones are being more and more used in many practical scenarios, such as surveillance, environmental monitoring, search and rescue in hardly-accessible areas, etc.. While a single drone can be guided by a human operator, the deployment of a swarm of multiple drones requires proper algorithms for automatic task-oriented control. In this paper, we focus on visual coverage optimization with drone-mounted camera sensors. In particular, we consider the specific case in which the coverage requirements are uneven, meaning that different parts of the environment have different coverage priorities. We model these coverage requirements with relevance maps and propose a deep reinforcement learning algorithm to guide the swarm. The paper first defines a proper learning model for a single drone, and then extends it to the case of multiple drones both with greedy and cooperative strategies. Experimental results show the performance of the proposed method, also compared with a standard patrolling algorithm.

The turbulent fluxes of momentum and sensible heat over the open sea during moderate to strong winds
Creators: name: Large, William George
Publisher: name: University of British Columbia
Year: 2010

description: Two systems for remote measurements of the air-sea fluxes of momentum, sensible heat and moisture during moderate to strong winds are described. One employs the dissipation method and the other the Reynolds flux or eddy correlation method. A modified Gill propeller-vane anemometer is the velocity sensor and a method of resolving the vertical velocity component, that accounts for the propeller's non-cosine behavior and avoids its non-linear operating region, is derived. The dynamic responses of the sensors are found from measurements in the actual turbulent conditions of the flux measurements. The results of an experiment on the Bedford tower, a stable platform moored in 59m of water 10 km offshore, are presented. Spectra, cospectra, turbulence statistics and transfer coefficients are calculated from the Reynolds flux velocity and temperature data and found to be comparable to previously reported values. Simultaneous dissipation and Reynolds flux estimates of both the momentum and sensible heat fluxes in up to 20 m/s winds are shown to be in excellent agreement. Also presented are the results of a second experiment where the systems were deployed on the weathership CCGS Quadra. A comparison of ship and tower drag coefficients from the dissipation system, demonstrates that the Bedford tower is essentially an open ocean site. The neutral drag coefficient, CDN, is found, on average, to be nearly constant at 1.14x10⁻³ for winds between 4 and 10 m/s and to increase almost linearly to about 2.18x10⁻³ at 26 m/s. No variation with either fetch (greater than 10 km) or stability is observed. Dissipation estimates of the sensible heat flux from a wide range of conditions are presented. The neutral transfer coefficient, CTN, is found, on average, to vary from about 0.69x10⁻³ in stable stratification to 1.08x10⁻³ in the unstable case. An increase in CTN with increasing wind speed is suggested by only some of the data. Time series of the fluxes are used to investigate additional sources of variation in the transfer coefficients. Their statistical variability about a running mean is seen to be about 10%. Evidence is presented that indicates that persistent departures from average values are related to sea surface conditions. CDN is observed to be significantly smaller, on average, during rising winds than during falling winds or after a change in wind direction.
Elementary school students with school adjustment problems
Creators: name: Link, Ilse
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to determine a way of identifying high-risk maladjusted students in order that they may receive counselling services before their problems become extreme. The study also attempted to obtain a specific description of attributes which characterize elementary school students with adjustment problems. This information would help teachers and counsellors to plan intervention programs suited to the needs of these children. The classroom teachers identified students in Grades 6 and 7 who had been referred for counselling because of school adjustment problems and they also identified students whom they considered to be well-adjusted to school. The study included 40 students, boys and girls. The California Test of Personality, Grades 4-8, Form AA, was administered to the students in order to determine their level of personal adjustment, social adjustment, and total adjustment. A sociogram was drawn up for each classroom to determine the sociometric status of the target group. The students were also compared on measures of family type, birth order, and family mobility. The results indicated that the problem students differed significantly from the well-adjusted students on measures of personal adjustment, social adjustment, total adjustment, sociometric status, and family mobility. Family type and birth order measures yielded non-significant results. The study showed that teacher identification of students with school adjustment problems was accurate. The study also indicated that the California Test of Personality, the sociogram, and a measure of family mobility were valid instruments for identifying high-risk students who were in need of counselling. These results can be of help to teachers and counsellors in collecting objective data on possible problem students and in identifying high-risk problem students early.

description: Tunnel junction between two superconductors is considered in the vicinity of the critical temperature. Superconductive fluctuations above Tc give rise to the noise of the ac Josephson current although the current itself is zero in average. As a result of fluctuations, current noise spectrum is peaked at the Josephson frequency, which may be considered as precursor of superconductivity in the normal state. Temperature dependence and shape of the Josephson current noise resonance line is calculated for various junction configurations.

description: Some recent efforts in compiling data for astrophysical purposes are introduced, which were discussed during a JINA-CARINA Collaboration meeting on "Nuclear Physics Data Compilation for Nucleosynthesis Modeling" held at the ECT* in Trento/ Italy from May 29th- June 3rd, 2007. The main goal of this collaboration is to develop an updated and unified nuclear reaction database for modeling a wide variety of stellar nucleosynthesis scenarios. Presently a large number of different reaction libraries (REACLIB) are used by the astrophysics community. The "JINA Reaclib Database" on http://www.nscl.msu.edu/ñero/db/ aims to merge and fit the latest experimental stellar cross sections and reaction rate data of various compilations, e.g. NACRE and its extension for Big Bang nucleosynthesis, Caughlan and Fowler, Iliadis et al., and KADoNiS. The KADoNiS (Karlsruhe Astrophysical Database of Nucleosynthesis in Stars, http://nuclear-astrophysics.fzk.de/kadonis) project is an online database for neutron capture cross sections relevant to the s process. The present version v0.2 is already included in a REACLIB file from Basel university (http://download.nucastro.org/astro/reaclib). The present status of experimental stellar $(n,γ)$ cross sections in KADoNiS is shown. A "high priority list" for measurements and evaluations for light charged-particle reactions set up by the JINA-CARINA collaboration is presented. The central web access point to submit and evaluate new data is provided by the Oak Ridge group via the http://www.nucastrodata.org homepage. "Workflow tools" aim to make the evaluation process transparent and allow users to follow the progress.

The effects of counselling methods on process and outcome
Creators: name: Higgins, Heather Marie
Publisher: name: University of British Columbia
Year: 2010

description: The differential effects of counselling methods applied to a conflict split were examined in an analogue study using forty two subjects, students in a graduate counselling programme, and seven therapists. The methods included Two Chair Role Playing; a therapeutic intervention drawn from Gestalt therapy, Focusing instructions followed by Empathic responses; and a Control, involving no therapy. Depth of Experiencing (Klein et al., I969) was the process dependent variable used to compare the differential effects of the two therapy conditions. Outcome measures, given to all subjects, included the Target Complaints Box Scale (Battle et al., 1966), awareness questions, a modified goal attainment scale, and subjective client reports. Fourteen subjects were randomly assigned to each of the three treatment conditions; subjects who received counselling sessions were randomly assigned to therapists with whom they engaged in a therapy session. The seven therapists each saw four clients. Two clients received Two Chair Role Playing sessions and two received sessions involving Focusing. The order of treatment presentation was counter balanced in order to eliminate any bias or practice effect. Because the Control subjects were not assigned to therapists, it was not possible to employ a fully crossed 7 x 3 (therapist-by-treatment) design. Two of the dependent variables were measured on more than one occasion, yielding a third repeated measures factor. Preliminary analysis using a 7 x 2 x r (therapist-by-treatment-by-occasion) fixed effects analysis of variance was performed. Results showed that sources of variance associated with therapists could be pooled at a level of significance of .25. Therefore, a 3 x r (treatment-by-occasion) design was employed. A fixed effects repeated measures analysis of variance was used where the trial factor was greater than one, and a one factor analysis of variance was performed when the dependent variable was measured on one occasion. The level of significance used was .05. Results showed Two Chair Role Playing to be more effective than Focusing in producing a greater number of peak, depth of experiencing scores, but there was no significant difference between the two groups on frequency of mode scores and on proportion mode and peak scores. There was no significant difference between Two Chair Role Playing and Focusing on any of the outcome measures. These two treatment groups did not differ from the Control on the Target Complaints Box Scale, or on the modified goal attainment scale. There was, however, a significant difference between each of these two groups and the Control on awareness questions and subjective client reports concerning the non-specific effects of counselling. These non-specific effects of counselling may be valuable indicators of what ingredients are necessary and effective in therapy. If clients deepen experiencing and achieve new awareness and self understanding, they may be then freed to put their energies into more creative living.

description: Assuming that the shallow-decaying phase in the early X-ray lightcurves of gamma-ray bursts (GRBs) is attributed to the dipole radiations (DRs) of a newborn magnetar, we present a comparative analysis for the magnetars born in death of massive stars and merger of compact binaries with long and short GRB (lGRB and sGRB) data observed with the {\em Swift} mission. We show that the typical braking index ($n$) of the magnetars is $\sim 3$ in the sGRB sample, and it is $\sim 4$ for the magnetars in the lGRB sample. Selecting a sub-sample of the magnetars whose spin-down is dominated by DRs ($n\lesssim 3$) and adopting a universal radiation efficiency of $0.3$, we find that the typical magnetic field strength ($B_p$) is $10^{16}$ G {\em vs.} $10^{15}$ G and the typical initial period ($P_0$) is $\sim 20$ ms {\em vs.} $2$ ms for the magnetars in the sGRBs {\em vs.} lGRBs. They follow the same relation between $P_0$ and the isotropic GRB energy as $ P_0\propto E_{\rm jet}^{-0.4}$. We also extend our comparison analysis to superluminous supernovae (SLSNe) and stable pulsars. Our results show that a magnetar born in merger of compact stars tends to have a stronger $B_p$ and a longer $P_0$ by about one order of magnitude than that born in collapse of massive stars. Its spin-down is dominated by the magnetic DRs as old pulsars, being due to its strong magnetic field strength, whereas the early spin-down of magnetars born in massive star collapse is governed by both the DRs and gravitational wave (GW) emission. A magnetar with a faster rotation speed should power a more energetic jet, being independent of its formation approach.

description: We propose a fast optically induced two-qubit \textsc{c-phase} gate between two resident spins in a pair of coupled quantum dots. An excited bound state which extends over the two dots provides an effective electron-electron exchange interaction. The gate is made possible by the electron-hole exchange interaction, which isolates a single transition in the system. When combined with appropriate single qubit rotations, this gate generates an entangled state of the two spins.

Gravo-thermodynamics of the Intracluster Medium: negative heat capacity and dilation of cooling time scales
Creators: name: Nusser, Adi
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The time scale for cooling of the gravitationally bound gaseous intracluster medium (ICM) is not determined by radiative processes alone. If the ICM is in quasi-hydrostatic equilibrium in the fixed gravitational field of the dark matter halo then energy losses incurred by the gravitational potential energy of the gas should also be taken into account. This "gravitational heating" has been known for a while using explicit solutions to the equations of motion. Here, we re-visit this effect by applying the virial theorem to gas in quasi-hydrostatic equilibrium in an external gravitational field, neglecting the gravity of the gas. For a standard NFW form of halo profiles and for a finite gas density, the response of the gas temperature to changes in the total energy is significantly delayed. The effective cooling time could be prolonged by more than an order of magnitude inside the scale radius ($\rs$) of the halo. Gas lying at a distance twice the scale radius, has negative heat capacity so that the temperature increases as a result of energy losses. Although external heating (e.g. by AGN activity) is still required to explain the lack of cool ICM near the center, the analysis here may circumvent the need for heating in farther out regions where the effective cooling time could be prolonged to become larger than the cluster age and also explains the increase of temperature with radius in these regions.

description: O crescimento constante e rápido da população mundial traz consigo vários problemas associados, como o aumento da procura por alimentos e, consequentemente, o uso de métodos agrícolas, muitas vezes inadequados, que podem levar à degradação e incapacitação dos solos. Além disso, todos os anos, cerca de 40% das culturas mundiais são perdidas, e ainda 820 milhões de pessoas são consideradas desnutridas. Deste modo, é de elevada importância encontrar novas formas e métodos para aumentar o rendimento agronómico, reduzindo a pegada agrícola, bem como, encontrar alternativas para os fertilizantes altamente poluentes usados atualmente. As cianobactérias e microalgas, presentes nas crostas biológicas do solo, correspondem a microrganismos fotoautotróficos, muito versáteis e com uma grande variedade de potenciais aplicações, nomeadamente como bioestimulantes e condicionadores dos solos. Esses organismos oferecem muitos benefícios aos solos e às plantas, não apenas potencializando e melhorando o crescimento e o desenvolvimento das plantas, mas também promovendo o restabelecimento de muitas propriedades dos solos degradados. Por um futuro mais sustentável, o possível uso destes microrganismos como bioestimulantes merece ser explorado como alternativa aos atuais métodos, fertilizantes e outros químicos agrícolas.

description: This article defines a pair of combinatorial operations on the combinatorial structure of compact right-angled hyperbolic polyhedra in dimension three called decomposition and edge surgery. It is shown that these operations simplify the combinatorics of such a polyhedron, while keeping it within the class of right-angled objects, until it is a disjoint union of Löbell polyhedra, a class of polyhedra which generalizes the dodecahedron. Furthermore, these combinatorial operations are shown to have geometric realizations which are volume decreasing. This allows for an organization of the volumes of right-angled hyperbolic polyhedra and allows, in particular, the determination of the polyhedra with smallest and second-smallest volumes.

We find that (i) there are no significant correlations between any NIR feature and the optical Mg2; (ii) the CaI, NaI and CO trace the alpha-enhancement; and (iii) the NIR absorption features are not influenced by the galaxy's age.

description: Facing an environment increasingly complex, uncertain and changing, even in crisis, organizations are driven to be agile in order to survive. Agility, at the core heart of business strategy, represents the ability to grow in a competitive environment of continuous and unpredictable changes with information systems perceived as one of its main enablers. In other words, to be agile, organizations must be able to rely on agile enterprise information systems/information technology (IT/IS). Since, the agility needs are not the same among stakeholders, the objective of this research is to develop a conceptual model for the achievement and assessment of IT/IS agility from balanced perspectives to support agile organizations. Several researches have indicated that the IT balanced scorecard (BSC) approach is an appropriate technique for evaluating IT performance. This paper provides a balanced-scorecard based framework to evaluate the IS agility through four perspectives: business contribution, user orientation, operation excellence and innovation and competitiveness. The proposed framework, called IS Agility BSC, propose a three layer structure for each of the four perspectives: mission, key success factors, and agility evaluation criteria. According to this conceptual model, enterprise information systems agility is measured according to 14 agility key success factors, over the four BSC Perspectives, using 42 agility evaluation criteria that are identified based on literature survey methodology. This paper explores agility in the broader context of the enterprise information systems. The findings will provide, for both researchers and practitioners, a practical approach for achieving and measuring IS agility performance to support organizations in attempt to become agile as a new condition of surviving in the new business world.

Teatro interculturale e corpi-in-relazione. AlmaTeatro e la questione dell'identità culturale oggi
Creators: name: Balma Tivola, Cristina
Publisher: name: Dipartimento delle Arti - Alma Mater Studiorum - Università di Bologna
Year: 2014

description: Abstract – IT
Le società complesse contemporanee vedono l'emergere sulla scena teatrale di realtà ed esperienze costituite da soggetti con origini culturali o nazionali diverse da quelle occidentali. Qualsiasi siano le pratiche adottate nel lavoro, tali casi si interrogano però sempre su questioni legate all'identità e alla diversità culturale che i membri di queste realtà esperiscono nella vita quotidiana, e su temi quali migrazioni, multiculturalità e interculturalità propri delle società in cui tale realtà emergono e/o si sviluppano. La letteratura prodotta sull'argomento è già consistente, e presenta un numero significativo di casi. I modelli teorici più utili per l'analisi di questi, dei loro processi produttivi e delle reti di relazione con la società sono stati elaborati da Gilbert e Lo e da Holledge e Tompkins. La presentazione di tali modelli si accompagna qui al loro ricorso nell'analisi dell'attività di una compagnia teatrale multi- e interculturale italiana, AlmaTeatro.
Abstract – EN
Complex contemporary societies see the emergence upon the scene of realities and experiences whose individuals are from cultural or national origins other than Westerners. Whatever the practices adopted for the work, these realities always face the issues of cultural identity and diversity on stage as well as in their members everyday lives, and issues such as immigration, multiculturalism and interculturalism politics of the society where these experiences emerge and/or develop. The literature produced on the topic is already substantial, and present a huge number of cases. The most useful theoretical models to analyze these, their production processes and the networks of relationship they hold with the society they relate to are those by Gilbert & Lo and Holledge & Tompkins. The presentation of these models is accompanied here by their application in the analysis of the activity of a multi-and intercultural Italian theatre company, AlmaTeatro.

description: We report on progress in ion placement into silicon devices with scanning probe alignment. The device is imaged with a scanning force microscope (SFM) and an aligned argon beam (20 keV, 36 keV) is scanned over the transistor surface. Holes in the lever of the SFM tip collimate the argon beam to sizes of 1.6 um and 100 nm in diameter. Ion impacts upset the channel current due to formation of positive charges in the oxide areas. The induced changes in the source-drain current are recorded in dependence of the ion beam position in respect to the FinFET. Maps of local areas responding to the ion beam are obtained.

description: The present study aims to investigate the study of double-diffusive convection on peristaltic flow under the assumption of long wavelength and low Reynolds number. The mathematical modelling for a two dimensional flow, along with double diffusion in nanofluids is considered. The motivation of the present research work is to analyse the effects of thermal radiation on a peristaltic flow through a porous medium in a non-uniform channel.The heat flux of the linear approximation employs the thermal radiation ofthe flow problem. The governing equations are analytically solved by using Homotopy Perturbation Sumudu Transformation method (HPSTM) with the help of the symbolic software Mathematica. The results of the velocity, pressure rise, temperature, Solutal(species)concentration and nanoparticle volume fraction profiles are graphically shown.

School closure : the effects of forced transfer on students entering grades eleven and twelve
Creators: name: Neumann, Ann Louise
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this longitudinal study was to investigate how senior students adjust to a new school when their school has been phased-out and closed. The specific problem investigated was the effect of forced school transfer on the academic performance, the self-concept, and the social adjustment of high school students entering grades eleven and twelve. Grade Point Average, the Adjective Check List, the California Test of Personality, the School Sentiment Index, the Neumann Research Questionnaire, and the incidence of absenteeism were the instruments selected to measure the dependent variables. The two independent variables were forced school transfer and grade level. As an external force manipulated the independent variable, a quasi-experimental--Nonequivalent Control Group design was used. There were five sample groups in this study, two experimental and three control, drawn from two school populations. All of the students were tested prior to the closure of Delbrook high school and one year after the closure. The findings and conclusions of this study were: 1. The academic performance of the transferred students did not differ from the academic performance of the students not required to transfer. 2. The self-concept of the transferred students did not differ from the self-concept of the students not required to transfer. 3. With two exceptions, the social adjustment of the transferred students did not differ from the social adjustment of the students not required to transfer. The students who transferred after grade eleven differed significantly from the other groups on two measures of social adjustment and had some difficulty integrating into their new school. 4. The grade level at which students were forced to change schools did not prove to be a significant factor in their total adjustment to their new school. The subjective measures indicate, however, that the students entering grade twelve were more negatively affected by the change of schools than the students entering grade eleven in the area of social adjustment.
Vortex dynamics in trapped Bose-Einstein condensate

description: We perform numerical simulations of vortex motion in a trapped Bose-Einstein condensate by solving the two-dimensional Gross-Pitaevskii Equation in the presence of a simple phenomenological model of interaction between the condensate and the finite temperature thermal cloud. At zero temperature, the trajectories of a single, off - centred vortex precessing in the condensate, and of a vortex - antivortex pair orbiting within the trap, excite acoustic emission. At finite temperatures the vortices move to the edge of the condensate and vanish. By fitting the finite -temperature trajectories, we relate the phenomenological damping parameter to the friction coefficients $α$ and $α^{'}$, which are used to describe the interaction between quantised vortices and the normal fluid in superfluid helium.

description: Time-domain seismic forward and inverse modeling for a dissipative medium is a vital research topic to investigate the attenuation structure of the Earth. Constant Q, also called frequency independence of the quality factor, is a common assumption for seismic Q inversion. We propose the first- and second-order nearly constant Q dissipative models of the generalized standard linear solid type, using a novel Q-independent weighting function approach. The two new models, which originate from the Kolsky model (a nearly constant Q model) and the Kjartansson model (an exactly constant Q model), result in the corresponding wave equations in differential form. Even for extremely strong attenuation (e.g., Q = 5), the quality factor and phase velocity for the two new models are close to those for the Kolsky and Kjartansson models, in a frequency range of interest. The wave equations for the two new models involve explicitly a specified Q parameter and have compact and simple forms. We provide a novel perspective on how to build a nearly constant Q dissipative model which is beneficial for time-domain large scale wavefield forward and inverse modeling. This perspective could also help obtain other dissipative models with similar advantages. We also discuss the extension beyond viscoacousticity and other related issues, for example, extending the two new models to viscoelastic anisotropy.
