description: The 2-m Liverpool Telescope (LT), owned by Liverpool John Moores University, is located in La Palma (Canary Islands) and operates in fully robotic mode. In 2005, the LT began conducting an automatic GRB follow-up program. On receiving an automatic GRB alert from a Gamma-Ray Observatory (Swift, INTEGRAL, HETE-II, IPN) the LT initiates a special override mode that conducts follow-up observations within 2-3 min of the GRB onset. This follow-up procedure begins with an initial sequence of short (10-s) exposures acquired through an r' band filter. These images are reduced, analyzed and interpreted automatically using pipeline software developed by our team called "LT-TRAP" (Liverpool Telescope Transient Rapid Analysis Pipeline); the automatic detection and successful identification of an unknown and potentially fading optical transient triggers a subsequent multi-color imaging sequence. In the case of a candidate brighter than r'=15, either a polarimetric (from 2006) or a spectroscopic observation (from 2007) will be triggered on the LT. If no candidate is identified, the telescope continues to obtain z', r' and i' band imaging with increasingly longer exposure times. Here we present a detailed description of the LT-TRAP and briefly discuss the illustrative case of the afterglow of GRB 050502a, whose automatic identification by the LT just 3 min after the GRB, led to the acquisition of the first early-time (< 1 hr) multi-color light curve of a GRB afterglow.

description: We focus on two types of coherent states, the coherent states of multi graviton states and the coherent states of giant graviton states, in the context of gauge/gravity correspondence. We conveniently use a phase shift operator and its actions on the superpositions of these coherent states. We find $N$-state Schrodinger cat states which approach the one-row Young tableau states, with fidelity between them asymptotically reaches 1 at large $N$. The quantum Fisher information of these states is proportional to the variance of the excitation energy of the underlying states, and characterizes the localizability of the states in the angular direction in the phase space. We analyze the correlation and entanglement between gravitational degrees of freedom using different regions of the phase space plane in bubbling AdS. The correlation between two entangled rings in the phase space plane is related to the area of the annulus between the two rings. We also analyze two types of noisy coherent states, which can be viewed as interpolated states that interpolate between a pure coherent state in the noiseless limit and a maximally mixed state in the large noise limit.

On the Roles of the Secondary Circulation in the Formation of Hurricanes

description: Secondary circulations (SC) associated with hurricanes are traditionally regarded as small perturbations superimposed on the primary circulations (PC). The reason behind this treatment roots in an observation that the magnitude of the SC is about 10 orders of magnitude smaller than that of the PC. This approximation underlines all of the hurricane theories up until now. Recently, Kieu (2004) proposes a revitalizing theory for the development of hurricanes for which a class of exact solutions of the primitive equations is obtained explicitly without appealing to scaling approximation. The solutions share some of the most important dynamical aspects with observations. According to this theory, the SC turns out to be particular important in determining the three-dimensional structure and temporal evolution of axisymmetric hurricanes. Like all theories for the hurricane development, Kieu's theory however contains an infinite growth of the SC with time. In this study, it will be shown that the infinite growth does not occur. In fact, the solution becomes stationary after a period of time and the SC is able to maintain itself without blowing exponentially if the nonlinear terms in the vertical momentum equation are included. In addition, the SC tends to force the peripheral convection to converge toward the center and builds up a more concentric vortex with a typical hurricane-eye structure. Some potential roles of the SC in the formation of hurricane eyes are discussed.

description: Using SU(3) lattice QCD, we perform the detailed studies of the three-quark and the multi-quark potentials. From the accurate calculation for more than 300 different patterns of 3Q systems, the static ground-state 3Q potential $V_{\rm 3Q}^{\rm g.s.}$ is found to be well described by the Coulomb plus Y-type linear potential (Y-Ansatz) within 1%-level deviation. As a clear evidence for Y-Ansatz, Y-type flux-tube formation is actually observed on the lattice in maximally-Abelian projected QCD. For about 100 patterns of 3Q systems, we perform the accurate calculation for the 1st excited-state 3Q potential $V_{\rm 3Q}^{\rm e.s.}$ by diagonalizing the QCD Hamiltonian in the presence of three quarks, and find a large gluonic-excitation energy $ΔE_{\rm 3Q} \equiv V_{\rm 3Q}^{\rm e.s.}-V_{\rm 3Q}^{\rm g.s.}$ of about 1 GeV, which gives a physical reason of the success of the quark model. $ΔE_{\rm 3Q}$ is found to be reproduced by the ``inverse Mercedes Ansatz'', which indicates a complicated bulk excitation for the gluonic-excitation mode. We study also the tetra-quark and the penta-quark potentials in lattice QCD, and find that they are well described by the OGE Coulomb plus multi-Y type linear potential, which supports the flux-tube picture even for the multi-quarks.

description: We present new results on the Eris/Dysnomia system including analysis of new images from the WFC3 instrument on the Hubble Space Telescope (HST). Seven HST orbits were awarded to program 15171 in January and February 2018, with the intervals between observations selected to sample Dysnomia over a full orbital period. Using relative astrometry of Eris and Dysnomia, we computed a best-fit Keplerian orbit for Dysnomia. Based on the Keplerian fit, we find an orbital period of 15.785899$\pm$0.000050 days, which is in good agreement with recent work. We report a non-zero eccentricity of 0.0062 at the 6.2-$σ$ level, despite an estimated eccentricity damping timescale of $\leq$17 Myr. Considering the volumes of both Eris and Dysnomia, the new system density was calculated to be 2.43$\pm$0.05 g cm$^{-3}$, a decrease of $\sim$4% from the previous value of 2.52$\pm$0.05 g cm$^{-3}$. The new astrometric measurements were high enough precision to break the degeneracy of the orbit pole orientation, and indicate that Dysnomia orbits in a prograde manner. The obliquity of Dysnomia's orbit pole with respect to the plane of Eris' heliocentric orbit was calculated to be 78.29$\pm$0.65$^{\circ}$ and is in agreement with previous work; the next mutual events season will occur in 2239. The Keplerian orbit fit to all the data considered in this investigation can be excluded at the 6.3-$σ$ level, but identifying the cause of the deviation was outside the scope of this work.

description: We show how 1+1-dimensional fermionic symmetry-protected topological states (SPTs, i.e. nontrivial short-range entangled gapped phases of quantum matter whose boundary exhibits 't Hooft anomaly and whose bulk cannot be deformed into a trivial tensor product state under finite-depth local unitary transformations only in the presence of global symmetries), indeed can be unwound to a trivial state by enlarging the Hilbert space via adding extra degrees of freedom and suitably extending the global symmetries. The extended projective global symmetry on the boundary can become supersymmetric in a specific sense, i.e., it contains group elements that do not commute with the fermion number parity $(-1)^F$, while the anti-unitary time-reversal symmetry becomes fractionalized. This also means we can uplift and remove certain exotic fermionic anomalies (e.g., "parity" anomaly in time-reversal or reflection symmetry) via appropriate supersymmetry extensions in terms of group extensions. We work out explicit examples for multi-layers of 1+1d Majorana fermion chains, then comment on models with Sachdev-Ye-Kitaev (SYK) interactions, intrinsic fermionic gapless SPTs protected by supersymmetry, and generalizations to higher spacetime dimensions via a cobordism theory.

description: In this paper we find an analytical solution of the equilibrium ion distribution for a toroidal model of a ionic channel, using the Perfect Screening Theorem (PST). The ions are charged hard spheres, and are treated using a variational Mean Spherical Approximation (VMSA) . Understanding ion channels is still a very open problem, because of the many exquisite tuning details of real life channels. It is clear that the electric field plays a major role in the channel behaviour, and for that reason there has been a lot of work on simple models that are able to provide workable theories. Recently a number of interesting papers have appeared that discuss models in which the effect of the geometry, excluded volume and non-linear behaviour is considered. We present here a 3D model of ionic channels which consists of a charged, deformable torus with a circular or elliptical cross section, which can be flat or vertical (close to a cylinder). Extensive comparisons to MC simulations were performed. The new solution opens new possibilities, such as studying flexible pores, and water phase transformations inside the pores using an approach similar to that used on flat crystal surfaces .

description: Hessian preconditioners are the key to efficient numerical solution of large-scale distributed parameter PDE-constrained inverse problems with highly informative data. Such inverse problems arise in many applications, yet solving them remains computationally costly. With existing methods, the computational cost depends on spectral properties of the Hessian which worsen as more informative data are used to reconstruct the unknown parameter field. The best case scenario from a scientific standpoint (lots of high-quality data) is therefore the worst case scenario from a computational standpoint (large computational cost). In this dissertation, we argue that the best way to overcome this predicament is to build data-scalable Hessian/KKT preconditioners---preconditioners that perform well even if the data are highly informative about the parameter. We present a novel data-scalable KKT preconditioner for a diffusion inverse problem, a novel data-scalable Hessian preconditioner for an advection inverse problem, and a novel data-scalable domain decomposition preconditioner for an auxiliary operator that arises in connection with KKT preconditioning for a wave inverse problem. Our novel preconditioners outperform existing preconditioners in all three cases: they are robust to large numbers of observations in the diffusion inverse problem, large Peclet numbers in the advection inverse problem, and high wave frequencies in the wave inverse problem.

description: We present a Ginzburg-Landau theory of ion-induced nucleation in a gas phase of polar one-component fluids, where a liquid droplet grows with an ion at its center. By calculating the density profile around an ion, we show that the solvation free energy is larger in gas than in liquid at the same temperature on the coexistence curve. This difference much reduces the nucleation barrier in a metastable gas.

Galactic Mass and Anisotropy Profile with Halo K-Giant and Blue Horizontal Branch Stars from LAMOST/SDSS and Gaia
Creators: name: Bird, Sarah
Publisher: name: Zenodo
Year: 2019

description: A major uncertainty in the determination of the mass profile of the Milky Way using stellar kinematics is the poorly determined anisotropy parameter, beta = 1 - ( ( (sigma_theta)**2 + (sigma_phi)**2 ) / ( 2 * (sigma_r)**2 ), where sigma_r is the Galactocentric radial velocity dispersion, and sigma_theta and sigma_phi are the tangential components of the velocity dispersion. We use a sample of over 16,000 Galactic halo K giant and blue horizontal branch stars from the LAMOST stellar spectroscopic survey and SDSS/SEGUE, combined with parallaxes and proper motions from Gaia DR2, to measure beta(r) over a wide range of Galactocentric distances r from 5 to 80 kpc. We investigate the extent to which a much improved knowledge of beta influences the determination of the Galactic mass profile M(r) as a function of r.
Verbal plurality and adverbial quantification : a case study of Skwxú7mesh (Squamish Salish)
Creators: name: Bar-El, Leora Anne
Publisher: name: University of British Columbia
Year: 2009

description: The goal of this thesis is to present an analysis of verbal plurality and adverbial quantification in Skwxwu7mesh (Squamish Salish). This thesis provides a detailed analysis of a phenomenon in Skwxwu7mesh that has never been explored: the effect of the auxiliary wa on predicates from various aspectual classes in both non-quantified and quantified sentences, wa has been described as a morpheme referring to a process that has duration either in the form of a single act or the regular performance of it (Kuipers 1967). Two central questions will be addressed in this thesis. Firstly, what is the function of the auxiliary wa in Skwxwu7mesh?. In other words, why is wa obligatorily present for certain interpretations of predicates and obligatorily absent for others; furthermore, what does wa do to a predicate to yield the various readings? Secondly, why is wa obligatory with adverbs of quantification? To answer these questions, this thesis proposes that wa is a pluractional marker that pluralizes the head of a predicate's event structure or the event type denoted by the predicate. Assuming Pustejovsky's (1991, 1995) event structure model representing the distinction between three primitive event types (states, processes, transitions), four aspectual classes are analyzed (activities , accomplishments , achievements and states) in both English and Skwxwu7mesh. This thesis argues that Skwxwu7mesh provides crucial evidence that all bare predicates (that is, predicates without wa) are telic, with the exception of individual-level predicates, wa causes a predicate to be atelic via pluralization; this atelicity is marked by continuous and/or habitual readings for the predicates of the various classes. As a consequence of these claims, this analysis suggests that activities and stage-level states are not primitives universally. This thesis argues that Kratzer's (1995) analysis of adverbs of quantification as unselective binders cannot account for Skwxwu7mesh; thus, adopting De Swart's (1993, 1995) event based approach to analyzing adverbial quantification, this thesis claims that Skwxwu7mesh provides crucial evidence that Q-adverbs quantify over events only. The evidence derives from the fact that the pluractional marker wa is obligatory with both stage-level stative predicates and individual-level predicates when they combine with a Q-adverb. The analysis presented in this thesis claims that wa is the source of the plurality of events over which a Q-adverb quantifies.

description: Quantum theory predicts and experiments confirm that nature can produce correlations between distant events that are nonlocal in the sense of violating a Bell inequality. Nevertheless, Bell's strong sentence {\it Correlations cry out for explanations} remains relevant. The maturing of quantum information science and the discovery of the power of nonlocal correlations, e.g. for cryptographic key distribution beyond the standard Quantum Key Distribution schemes, strengthen Bell's wish and make it even more timely. In 2003, Leggett proposed an alternative model for nonlocal correlations [Found. Phys. 33, 1469 (2003)], that he proved to be incompatible with quantum predictions. We present here a new approach to this model, along with new inequalities for testing it. Remarkably these inequalities can be derived in a very simple way, assuming only the non-negativity of probability distributions; they are also stronger than previously published Leggett-type inequalities. The simplest of these inequalities is experimentally violated. Then we go beyond Leggett's model, and show that one cannot ascribe even partially defined individual properties to the components of a maximally entangled pair.

description: Twisted bilayer graphene with tiny rotation angles have drawn significant attention due to the observation of the unconventional superconducting and correlated insulating behaviors. In this paper, we employ a full tight-binding model to investigate collective excitations in twisted bilayer graphene near magic angle. The polarization function is obtained from the tight-binding propagation method without diagonalization of the Hamiltonian matrix. With the atomic relaxation considered in the simulation, damped and undamped interband plasmon modes are discovered near magic angle under both room temperature and superconductivity transition temperature. In particular, an undamped plasmon mode in narrow bands can be directly probed in magic angle twisted bilayer graphene at superconductivity transition temperature. The undamped plasmon mode is tunable with angles and gradually fades away with both temperature and chemical potential. In practice, the flat bands in twisted bilayer graphene can be detected by exploring the collective plasmons from the measured energy loss function.
Functional and mutational analysis of the cellulose binding domain CBDN1 from Cellulomonas fimi [Beta]-glucanase C (CenC)
Creators: name: Kormos, Jeffery Michael
Publisher: name: University of British Columbia
Year: 2009

description: Endoglucanase C (CenC), a ß,1-4 glucanase from the soil bacterium Cellulomonas fimi binds to cellulose via the cellulose binding domains N l (CBDN1), and N2 (CBDN2). In this thesis, the contribution of 10 amino acids within the binding cleft of CBDN1 was evaluated by alanine mutagenesis. Each mutant was analyzed for binding to an insoluble allomorph of cellulose (phosphoric acid swollen Avicel), and a soluble glucopyranoside polymer (barley ß-glucan). All ten mutations affected the binding affinity of CBDN1 to some extent; Y19 and Y85 were identified as the two residues most essential for tight binding to insoluble cellulose and barley ß-glucan. The structural integrity and intermolecular contacts of Y19A and Y85A were assessed using two-dimensional NMR spectrospcopy and UV resonance Raman spectroscopy (UVRRS). Both techniques indicated that Y85A is similar to wild-type CBDN1 in structure, but that Y19A exhibits some structural perturbations in the binding cleft. In addition, UVRRS data indicated that Y85 forms a direct hydrogen bond to cellulose upon binding, but Y19 does not. Taken together, these data imply that CBDN1 binding is mediated by two tyrosine residues, one of which interacts directly with cellulose, the other important for structural integrity of the binding cleft.

Rapid orbital expansion in millisecond pulsar PSR J0636+5128: evaporation winds?

description: PSR J0636+5128 is a 2.87 ms binary millisecond pulsar (MSP) discovered by the Green Bank Northern Celestial Cap Pulsar Survey, and possesses the third shortest orbital period ($P=1.6$ hour) among confirmed binary pulsars. Recent observations reported that this source is experiencing a rapid orbital expansion at a rate of $\dot{P}=(1.89\pm0.05)\times 10^{-12}~\rm s\,s^{-1}$. The evaporation winds of the companion induced by the spin-down luminosity of the MSP may be responsible for such a positive orbital period derivative. However, our calculations show that the winds ejecting from the vicinity of the companion or the inner Lagrangian point can not account for the observation due to an implausible evaporation efficiency. Assuming that the evaporation winds eject from the vicinity of the MSP in the form of asymmetry disc winds or outflow, the evaporation efficiency can be constrained to be $\sim 0.1$. Therefore, the rapidly orbital expansion detected in PSR J0636+5128 provides evidence of outflows and accretion disc around the MSP.

description: The hexactinellid sponge genera Casearia Quenstedt, Caseispongia Quenstedt, and Cypellia Pomel are all morphologically similar and externally annulated. Caseispongia is internally a chambered sponge, like the hypercalcified genus Amblysiphonella . The internal construction of almost all externally annulated specimens illustrated as Casearia by Quenstedt and some other authors is not known enough. Despite of this lack of knowledge the genus name Caseispongia is synonymized with Casearia based on observations of Müller and the description of Schmidel. Both genera were described originally from the Upper Jurassic of southern Germany. Hexactinellid sponges, described in this paper, are reported for the first time from the Jurassic of the Shotori Mountains in east-central Iran. The following species are new to science: Casearia tabasensis , Cypellia irregularis , C. cylindrica , and C. tabulata .

description: In many forecast evaluation applications, standard tests (e.g., Diebold and Mariano, 1995) as well as tests allowing for time-variation in relative forecast ability (e.g., Giacomini and Rossi, 2010) build on heteroskedasticity-and-autocorrelation consistent (HAC) covariance estimators. Yet, the finite-sample performance of these asymptotics is often poor. "Fixed-b" asymptotics (Kiefer and Vogelsang, 2005), used to account for long-run variance estimation, improve finitesample performance under homoskedasticity, but lose asymptotic pivotality under time-varying volatility. Moreover, loss of pivotality due to time-varying volatility is found in the standard HAC framework in certain cases as well. We prove a wild bootstrap implementation to restore asymptotically pivotal inference for the above and new CUSUM- and Cramér-von Mises based tests in a fairly general setup, allowing for estimation uncertainty from either a rolling window or a recursive approach when fixed-b asymptotics are adopted to achieve good finite-sample performance. We then investigate the (time-varying) performance of professional forecasters relative to naive no-change and model-based predictions in real-time. We exploit the Survey of Professional Forecasters (SPF) database and analyze nowcasts and forecasts at different horizons for output and inflation. We find that not accounting for time-varying volatility seriously affects outcomes of tests for equal forecast ability: wild bootstrap inference typically yields convincing evidence for advantages of the SPF, while tests using non-robust critical values provide remarkably less. Moreover, we find significant evidence for time-variation of relative forecast ability, the advantages of the SPF weakening considerably after the "Great Moderation".

title: Untersuchung des intrinsischen Ausschaltvermögens eines Modellvakuumschalters und der Wechselwirkungen mit der Prüfumgebung zur Optimierung von Kontaktwerkstoffen

description: In der Entwicklung von Kontaktwerkstoffen für die Anwendung in Vakuumschaltgeräten kann in der Regel kein kausaler Zusammenhang zwischen den Eigenschaften eines Werkstoffes und den Schalteigenschaften eines Schalters hergestellt werden. Die Komplexität der Stromunterbrechung im Vakuum, die Vielzahl der Einflussgrößen zwischen dem Kontaktwerkstoff und dem Schaltverhalten des Schalters sowie die oftmals widersprüchlichen Anforderungen an die Werkstoffeigenschaften verhindern für gewöhnlich die unmittelbare Rückführung einer Veränderung in den Schalteigenschaften auf ihre Ursache. Daher wird der Einfluss geringfügiger Veränderungen in der Herstellung von festphasengesinterten Verbundwerkstoffen, wie beispielsweise der Einfluss von Änderungen in der Werkstoff-Mikrostruktur oder der Chromproduktionscharge, noch immer kontrovers diskutiert. In der vorliegenden Arbeit werden daher mögliche Einflüsse der Mikrostruktur und der Chromproduktionscharge festphasengesinterter CuCr-Verbundwerkstoffe auf das Ausschaltvermögen eines Modellschalters untersucht und bestmöglich isoliert. Für einen möglichst direkten Zusammenhang zwischen dem Kontaktwerkstoff und dem Ausschaltvermögen wird auf Magnetfeldkontakte verzichtet, die wiederkehrende Spannung wird auf Werte unter 1 kV begrenzt. Die Komplexität der Stromunterbrechung und die Anzahl der beeinflussenden Parameter werden auf ein Minimum reduziert. Einflüsse aus der Prüfumgebung auf das Ausschaltvermögen werden systematisch ausgewertet, um Störgrößen zu identifizieren, ihren Einfluss zu limitieren und um relative Veränderungen des Ausschaltvermögens einordnen zu können. Die Untersuchung des Ausschaltvermögens der Kontaktwerkstoffe erfolgt schließlich in einer standardisierten und auf Reproduzierbarkeit optimierten Prüfumgebung. Die Ergebnisse legen nahe, dass das Ausschaltvermögen der Kontaktwerkstoffe unter den gegebenen Versuchsbedingungen auf grundlegende Veränderungen in der Mikrostruktur und der Chromcharge nicht reagiert. Die auftretenden Wiederzündungsmechanismen sind unsensibel für die genannten Veränderungen der Kontaktwerkstoffe. Zur Bewertung der Ergebnisse werden die Mikrostruktur der Werkstoffe nach den Kurzschlussunterbrechungen sowie die Entladungszustände der Schaltstrecke ausgewertet. Anhand der Wiederzündungszeitpunkte und des Reststromverhaltens der Schaltstrecke werden Rückschlüsse auf mögliche Wiederzündungsmechanismen gezogen. Der kritische Wiederzündungsmechanismus scheint nicht mit "Townsend-ähnlichen" Elektronenlawinen in Verbindung zu stehen, sondern mit oberflächenabhängigen Vorgängen in Zusammenhang mit "liquid protrusions" oder Metalltropfen.

description: Given the dramatic changes triggered by the Corona pandemic, the question arises whether it has displaced people’s concerns about climate change and whether Corona-related financial losses among affected households can influence their assessment of climate change. Based on a survey among more than 6,000 German household heads conducted in the period spanning from May 18 to June 14, 2020, this paper provides empirical evidence on the impact of the pandemic on perceptions of climate change and climate policy, as well as the extent to which respondents are affected in terms of health and finances. Although the majority of almost 77% of the respondents is concerned about their own health and that of their families, according to our descriptive results, climate change appears to remain an important issue: only six percent of the respondents feel that climate change has become less important since the beginning of 2020, while about 70% of the respondents see no change in the importance of the issue. Yet, employing discrete-choice models, our estimation results indicate that households that suffered from Coronarelated financial losses consider climate change to be less important than households that remained unaffected in this respect. In accord with Engler et al. (2020), we thus conclude that lowering individual financial losses is not only relevant from a social perspective, but it is also critical for the acceptance of climate policy measures.

Captures of Red Giant Stars by Black Holes in Elliptical Galaxies: Feedback to the Hot Gas

description: The highly disturbed hot gas in elliptical galaxies, as revealed in many {\em Chandra} X-ray images, implies a source of energy in the galactic nucleus. In some elliptical galaxies faint X-ray ``ghost'' cavities appear without corresponding radio lobes. It has been suggested that ghost cavities are caused by short-lived activity with a timescale of $\sim 10^3-10^4$ years, but this is difficult to understand within the popular paradigm of active galactic nuclei. We suggest an episode model for ghost cavities, invoking captures of red giant stars by the black hole located at the center of the elliptical galaxies at a typical rate of $10^{-5}$yr$^{-1}$ per galaxy. The accretion of tidally disrupted red giant stars onto the black hole powers activity in a timescale of a few years. The total energy channeled into the jet/outflow during the cooling time of the hot gas is $\sim 10^{56}$ erg, which is the typical work required to form the observed cavities. In this scenario, the faint cavities are produced by the feedback following accretion of the debris of the captured red giant stars onto the black holes. We apply the present model to several elliptical galaxies and find that it can explain the formation of the ghost cavities. This model can be tested in the future by comparisons between radio and X-ray observations.

Planetary Nebulae as Probes of Stellar Populations

Publisher: name: arXiv
Year: 2006

subject: FOS: Physical sciences

description: Planetary nebulae (PNe) have the potential to revolutionize our understanding of extragalactic stellar populations. Indeed, in many systems, bright PNe are the only individual objects identifiable from the ground, and, even more often, they are the only stars that are amenable to spectroscopy. We review the ways in which ensembles of PNe can be used to probe the metallicity, age, and history of a stellar population. In particular, we discuss three cases: the weak line spectroscopic regime, where one has knowledge of the line-strengths of faint forbidden lines such as [O III] 4363, a bright-line regime, where only the strongest emission lines are visible, and the photometric regime, where the only information available is the [O III] 5007 luminosity function. We show that each of these cases, when properly calibrated, can provide unique insights into the objects that make up a stellar population.

description: In this paper, we compare the performance, stability and robustness of Artificial Neural Networks (ANN) and Boosted Decision Trees (BDT) using MiniBooNE Monte Carlo samples. These methods attempt to classify events given a number of identification variables. The BDT algorithm has been discussed by us in previous publications. Testing is done in this paper by smearing and shifting the input variables of testing samples. Based on these studies, BDT has better particle identification performance than ANN. The degradation of the classifications obtained by shifting or smearing variables of testing results is smaller for BDT than for ANN.

Information Spectrum Approach to Second-Order Coding Rate in Channel Coding
Creators: name: Hayashi, Masahito
Publisher: name: arXiv
Year: 2008
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Second-order coding rate of channel coding is discussed for general sequence of channels. The optimum second-order transmission rate with a constant error constraint $ε$ is obtained by using the information spectrum method. We apply this result to the discrete memoryless case, the discrete memoryless case with a cost constraint, the additive Markovian case, and the Gaussian channel case with an energy constraint. We also clarify that the Gallager bound does not give the optimum evaluation in the second-order coding rate.

Publisher: name: Новгородский государственный университет имени Ярослава Мудрого (НовГУ)
Year: 2021

description: Главная тема романа «Авиатор», подчиняющая себе остальные, — личность и время. Герой, человек Серебряного века, воссоздает свою личность и свое время через воспоминания. Целостная картина постепенно складывается из перемежающихся эпизодов, всплывающих в памяти. Воспоминания персонажей всегда присутствовали в литературе, в романе Водолазкина они стали сюжетным стержнем. «Авиатор» вписан в широкий и многослойный литературный контекст. Сюжет, организация повествования, проблематика, идеи, образный ряд, имена персонажей, — всё пронизано ассоциациями, перекличками, реминисценциями, отсылками. Большей частью литературные связи лежат на поверхности, создавая впечатление их намеренности. Автор словно дает понять, что любую тему или идею современный писатель обречен раскрывать в давно заданных литературой координатах.
