description: (ABRIDGED) We describe the first results of the ALHAMBRA survey which provides cosmic tomography of the evolution of the contents of the Universe over most of Cosmic history. Our approach employs 20 contiguous, equal-width, medium-band filters covering from 3500 to 9700 A, plus the JHKs bands, to observe an area of 4 sqdeg on the sky. The optical photometric system has been designed to maximize the number of objects with accurate classification by SED and redshift, and to be sensitive to relatively faint emission lines. The observations are being carried out with the Calar Alto 3.5m telescope using the cameras LAICA and O-2000. The first data confirm that we are reaching the expected magnitude limits of AB

description: All-sky imaging surveys have identified several dozen isolated planetary-mass objects (IPMOs), far away from any star. Here, we examine the prospects for detecting transiting moons around these objects. We expect transiting moons to be common, occurring around 10-15% of IPMOs, given that close-orbiting moons have a high geometric transit probability and are expected to be a common outcome of giant planet formation. IPMOs offer an advantage over other directly imaged planets in that high-contrast imaging is not necessary to detect the photometric transit signal. For at least 30 (>50%) of the currently known IPMOs, observations of a single transit with the James Webb Space Telescope would have low enough forecasted noise levels to allow for the detection of an Io-like or Titan-like moon. Intrinsic variability of the IPMOs will be an obstacle. Using archival time-series photometry of IPMOs with the Spitzer Space Telescope as a proof-of-concept, we found evidence for a fading event of 2MASS J1119-1137 AB that might have been caused by intrinsic variability, but is also consistent with a single transit of a habitable-zone 1.7$R_\oplus$ exomoon. Although the interpretation of this particular event is inconclusive, the characteristics of the data and the candidate signal suggest that Earth-sized habitable-zone exomoons around IPMOs are detectable with existing instrumentation.

description: Provincial income assistance caseloads declined from April 2020 to October 2020, with some provinces seeing larger declines in caseloads than others. One reason for this was that provinces treated income from the Canadian Emergency Response Benefit (CERB) differently not only for the purposes of eligibility for income assistance but also for determining income assistance benefits. The result was many provinces were able to dramatically reduce their income assistance expenditures by temporarily shifting the cost to the federal government.

description: We report new continuum observations of fourteen z~6 quasars at 250 GHz and fourteen quasars at 1.4 GHz. We summarize all recent millimeter and radio observations of the sample of the thirty-three quasars known with 5.71<=z<=6.43, and present a study of the rest frame far-infrared (FIR) properties of this sample. These quasars were observed with the Max Plank Millimeter Bolometer Array (MAMBO) at 250 GHz with mJy sensitivity, and 30% of them were detected. We also recover the average 250 GHz flux density of the MAMBO undetected sources at 4 sigma, by stacking the on-source measurements. The derived mean radio-to-UV spectral energy distributions (SEDs) of the full sample and the 250 GHz non-detections show no significant difference from that of lower-redshift optical quasars. Obvious FIR excesses are seen in the individual SEDs of the strong 250 GHz detections, with FIR-to-radio emission ratios consistent with that of typical star forming galaxies. Most 250 GHz-detected sources follow the L_{FIR}--L_{bol} relationship derived from a sample of local IR luminous quasars (L_{IR}>10^{12}L_{\odot}), while the average L_{FIR}/L_{bol} ratio of the non-detections is consistent with that of the optically-selected PG quasars. The MAMBO detections also tend to have weaker Lyαemission than the non-detected sources. We discuss possible FIR dust heating sources, and critically assess the possibility of active star formation in the host galaxies of the z~6 quasars. The average star formation rate of the MAMBO non-detections is likely to be less than a few hundred M_{\odot} yr^{-1}, but in the strong detections, the host galaxy star formation is probably at a rate of \gtrsim10^{3} M_{\odot} yr^{-1}, which dominates the FIR dust heating.

description: We derive rates of contraction of posterior distributions on nonparametric or semiparametric models based on Gaussian processes. The rate of contraction is shown to depend on the position of the true parameter relative to the reproducing kernel Hilbert space of the Gaussian process and the small ball probabilities of the Gaussian process. We determine these quantities for a range of examples of Gaussian priors and in several statistical settings. For instance, we consider the rate of contraction of the posterior distribution based on sampling from a smooth density model when the prior models the log density as a (fractionally integrated) Brownian motion. We also consider regression with Gaussian errors and smooth classification under a logistic or probit link function combined with various priors.

description: We study the dynamics of the scalar field FLRW flat cosmological models within the framework of the Unified Dark Matter (UDM) scenario. In this model we find that the main cosmological functions such as the scale factor of the Universe, the scalar field, the Hubble flow and the equation of state parameter are defined in terms of hyperbolic functions. These analytical solutions can accommodate an accelerated expansion, equivalent to either the dark energy or the standard $Λ$ models. Performing a joint likelihood analysis of the recent supernovae type Ia data and the Baryonic Acoustic Oscillations traced by the SDSS galaxies, we place tight constraints on the main cosmological parameters of the UDM cosmological scenario. Finally, we compare the UDM scenario with various dark energy models namely $Λ$ cosmology, parametric dark energy model and variable Chaplygin gas. We find that the UDM scalar field model provides a large and small scale dynamics which are in fair agreement with the predictions by the above dark energy models although there are some differences especially at high redshifts.

Monte Carlo simulations using an R-matrix formalism lead to the conclusion that the ^AHe resonance states play a significant role in the break-up of these states. The results exclude an earlier assumption of a phase-space description of the break-up process of the 18.15 MeV state. Evidence for extra sequential decay paths is found for both states.

description: We report the discovery of the brightest detached binary white dwarfs with periods less than an hour, which provide two new gravitational wave verification binaries for the Laser Interferometer Space Antenna (LISA). The first one, SMSS J033816.16$-$813929.9 (hereafter J0338), is a 30.6 min orbital period, $g=17.2$ mag detached double white dwarf binary with a Gaia parallax measurement that places it at a distance of 533 pc. The observed radial velocity and photometric variability provide precise constraints on the system parameters. J0338 contains a $0.230 \pm 0.015~M_{\odot}$ white dwarf with a $0.38_{-0.03}^{+0.05}~M_{\odot}$ companion at an inclination of $69 \pm 9^{\circ}$. The second system, SDSS J063449.92+380352.2 (hereafter J0634), is a 26.5 min orbital period, $g=17.0$ mag detached double white dwarf binary at a distance of 435 pc. J0634 contains a $0.452^{+0.070}_{-0.062}~M_{\odot}$ white dwarf with a $0.209^{+0.034}_{-0.021}~M_{\odot}$ companion at an inclination of $37 \pm 7^{\circ}$. The more massive white dwarf in J0634 is hotter than its companion, even though tidal dissipation is predicted to be relatively inefficient at such periods. This suggests that the more massive white dwarf formed last. J0338 and J0634 will be detected by LISA with a signal-to-noise ratio of 5 and 19, respectively, after four years. We identified these two systems based on their overluminosity and $u$-band photometry. Follow-up of $u$-band selected Gaia targets will likely yield additional LISA verification binaries.

A new model for QPOs in accreting black holes: application to the microquasar GRS 1915+105
Creators: name: Petri, J.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: (abridged) In this paper we extend the idea suggested previously by Petri (2005a,b) that the high frequency quasi-periodic oscillations observed in low-mass X-ray binaries may be explained as a resonant oscillation of the accretion disk with a rotating asymmetric background (gravitational or magnetic) field imposed by the compact object. Here, we apply this general idea to black hole binaries. It is assumed that a test particle experiences a similar parametric resonance mechanism such as the one described in paper I and II but now the resonance is induced by the interaction between a spiral density wave in the accretion disk, excited close to the innermost stable circular orbit, and vertical epicyclic oscillations. We use the Kerr spacetime geometry to deduce the characteristic frequencies of this test particle. The response of the test particle is maximal when the frequency ratio of the two strongest resonances is equal to 3:2 as observed in black hole candidates. Finally, applying our model to the microquasar GRS 1915+105, we reproduce the correct value of several HF-QPOs. Indeed the presence of the 168/113/56/42/28 Hz features in the power spectrum time analysis is predicted. Moreover, based only on the two HF-QPO frequencies, our model is able to constrain the mass $M_{\rm BH}$ and angular momentum $a_{\rm BH}$ of the accreting black hole.

Static friction at fractal interfaces

description: Tribological phenomena are governed by combined effects of material properties, topology and surface-chemistry. We study the interplay of multiscale surface structures with molecular-scale interactions towards interpreting static frictional interactions at fractal interfaces. By spline-assisted-discretization we analyse asperity interactions in pairs of contacting fractal surface-profiles. For elastically deforming asperities, force analysis reveals greater friction at surfaces exhibiting higher fractality, with increasing molecular-scale friction amplifying this trend. Increasing adhesive strength yields higher overall friction at surfaces of lower fractality owing to greater true-contact-area. In systems where adhesive-type interactions play an important role, such as those where cold-welded junctions form, friction is minimised at an intermediate value of surface profile fractality found to be around 1.3 to 1.5. Results have implications for systems exhibiting evolving surface structures.
Animal imagery in the poetry of Ted Hughes
Creators: name: Hackett, Joanetta Daphne
Publisher: name: University of British Columbia
Year: 2010

description: Animal imagery is an important element in the poetry of Ted Hughes. These images, catalogued in this thesis, constitute an emblematic bestiary which helps convey Hughes's most important themes: heroism and survival, myth, attitudes to sexuality, and the role and function of the poet. Implicit in Hughes's thematic explorations is his essentially pessimistic world view of a polarized Manichean universe in which many elements of life are in disintegration. Hughes perceives the traditional role of the hero as incongruous with the fragmented consciousness of modern man. What emerges now as heroic is the will and endurance necessary for survival or for the acceptance of the ultimate merging of the self into the great processes of life. Hughes asserts also the need of man for some mythological framework within which to comprehend what he calls "the elemental power circuit of the universe." Animal images are the central focus for Hughes's important mythic presentations: metamorphosis as an image of the indestructibility of life, and the god-animal as symbol for creative and destructive forces in nature. Sexuality is such a creative force; the uninhibited actions of animals provide Hughes with useful images for his explorations of the attitudes and sexual practices of modern man. On a personal level, he sees sexual attraction as first savagely absorbing, then confining and stifling. However, Hughes views fecundity as a process linking man with all other life forms, providing a sort of immortality through the continuous wheel of life and death. The most central theme in the poetry of Hughes is a consideration of the nature and scope of the role of the artist. Hughes uses a wide range of animal images to suggest aspects of the poetic persona and to explore facets of the artist as both hunter and prey. Animal images present the role of the poet variously as prophet, critic, trickster or fool, most notably in the case of Crow. These themes culminate in "Gaudete", Hughes's most recently published book. They are presented in part through an emblematic bestiary and in part, through the "animal" nature of the central character, the Reverend Nicholas Lumb plus his demonic double, who becomes, microcosmically, a representative of the physical, sexual, "animal" side of man.

description: In this paper, we concern about applying general relativistic tests on the spacetime produced by a static black hole associated with cloud of strings, in a universe filled with quintessence. The four tests we apply are precession of the perihelion in the planetary orbits, gravitational redshift, deflection of light, and the Shapiro time delay. Through this process, we constrain the spacetime's parameters in the context of the observational data, which results in about $\sim 10^{-9}$ for the cloud of strings parameter, and $\sim 10^{-20}$ m$^{-1}$ for that of quintessence. The response of the black hole to the gravitational perturbations is also discussed.

description: The paper deals with the variational principles for evaluation of the spectral radii of transfer and weighted shift operators associated with a dynamical system. These variational principles have been the matter of numerous investigations and the principal results have been achieved in the situation when the dynamical system is either reversible or it is a topological Markov chain. As the main summands these principles contain the integrals over invariant measures and the Kolmogorov--Sinai entropy. In the article we derive the Variational Principle for an arbitrary dynamical system. It gives the explicit description of the Legendre dual object to the spectral potential. It is shown that in general this principle contains not the Kolmogorov--Sinai entropy but a new invariant of entropy type -- the t-entropy.

Peningkatan Kemampuan Minyak Kelapa Sebagai Phase Change Material Dengan Menggunakan Fly Ash Untuk Mengendalikan Temperatur Ruang Dalam

description: Penggunaan dinding berbasis PCM minyak kelapa bercampur dengan fly ash  akan memiliki pengaruh yang signifikan dalam mengendalikan temperatur udara di dalam ruangan. Pengguna bangunan akan dapat memperoleh kenyamanan termal karena temperatur udara di dalam ruang dapat ditunda peningkatannya dibandingkan tidak menggunakan dinding penukar kalor. Lingkungan termal ruang dalam rumah tinggal berdinding bata di siang hari akan meningkat seiring dengan meningkatnya temperatur udara di luar ruangan dan biasanya masuk dalam kategori yang tidak nyaman secara termal karena melebihi batas maksimal penghuni merasa nyaman (24-26 C).  

Minyak kelapa memiliki kemampuan sebagai PCM yang memiliki titik beku dan titik lebur dalam range kenyamanan manusia. Selain itu, minyak kelapa juga mudah didapatkan di pasaran menjadikan minyak kelapa memiliki nilai ekonomis jika digunakan sebagai PCM. Dalam penelitian sebelumnya, kemampuan minyak kelapa masih belum maksimal karena selisih temperatur yang cukup kecil dengan lingkungan sekitar. Kemampuan ini dapat ditingkatkan dengan menambahkan fly ash sebagai penyerap kalor yang lebih efektif karena memiliki unsur logam didalamnya. Dengan penggabungan dua material ini, diharapkan kemampuan dari minyak kelapa dapat lebih maksimal sehingga dapat menunda waktu kenaikan temperatur di dalam ruangan. Pencampuran kedua material ini perlu dilakukan dan dilakukan pengukuran kembali seperti yang dilakukan Jurizat dan Wonorahardjo (2018) dengan menggunakan bentuk wadah dan dimensi tertentu yang kemudian disebut kapsul PCM.

Kapsul PCM yang digunakan dalam penelitian kemudian digunakan ke dalam dinding partisi ruangan sebagai model penukar kalor. Pemasangan dinding partisi dilakukan di dalam ruangan untuk menghindari dugaan adanya pengaruh terhadap urban heat island serta menjamin kualitas dinding terjaga. Dengan demikian, dinding partisi yang telah dimasukkan kapsul PCM memiliki fungsi sebagai pembatas ruangan (fungsionalitas), struktur (kekuatan dan ketahanan), estetika, dan juga pengendali termal di dalam ruangan.

Dari metode pelaksanaan yang sudah dilakukan sebelumnya, simulasi dilakukan dengan menggunakan sistem komputasi untuk mengetahui hipotesis awal dari kemampuan dinding penukar kalor menggunakan aplikasi Rhinoceros dan Ladybug. Hasil simulasi menunjukkan bahwa dinding penukar kalor dapat menurunkan temperatur udara di dalam ruang sebesar 2 C. Simulasi ini menjadi landasan awal dalam eksperimen yang dilakukan selanjutnya.

description: Using HST-COS FUV spectra, we have discovered warm molecular hydrogen in the TWA 7 system. TWA 7, a $\sim$9 Myr old M2.5 star, has a cold debris disk and has previously shown no signs of accretion. Molecular hydrogen is expected to be extremely rare in a debris disk. While molecular hydrogen can be produced in star spots or the lower chromospheres of cool stars such as TWA 7, fluxes from progressions that get pumped by the wings of Ly$α$ indicate that this molecular hydrogen could be circumstellar and thus that TWA 7 is accreting at very low levels and may retain a reservoir of gas in the near circumstellar environment.

description: One of the most central and long-standing open questions in combinatorial design theory concerns the existence of Steiner t-designs for large values of t. Although in his classical 1987 paper, L. Teirlinck has shown that non-trivial t-designs exist for all values of t, no non-trivial Steiner t-design with t > 5 has been constructed until now. Understandingly, the case t = 6 has received considerable attention. There has been recent progress concerning the existence of highly symmetric Steiner 6-designs: It is shown in [M. Huber, J. Algebr. Comb. 26 (2007), pp. 453-476] that no non-trivial flag-transitive Steiner 6-design can exist. In this paper, we announce that essentially also no block-transitive Steiner 6-design can exist.

description: A new approach of coordination of decisions in a multi site system is proposed. It is based this approach on a multi-agent concept and on the principle of distributed network of enterprises. For this purpose, each enterprise is defined as autonomous and performs simultaneously at the local and global levels. The basic component of our approach is a so-called Virtual Enterprise Node (VEN), where the enterprise network is represented as a set of tiers (like in a product breakdown structure). Within the network, each partner constitutes a VEN, which is in contact with several customers and suppliers. Exchanges between the VENs ensure the autonomy of decision, and guarantiee the consistency of information and material flows. Only two complementary VEN agents are necessary: one for external interactions, the Negotiator Agent (NA) and one for the planning of internal decisions, the Planner Agent (PA). If supply problems occur in the network, two other agents are defined: the Tier Negotiator Agent (TNA) working at the tier level only and the Supply Chain Mediator Agent (SCMA) working at the level of the enterprise network. These two agents are only active when the perturbation occurs. Otherwise, the VENs process the flow of information alone. With this new approach, managing enterprise network becomes much more transparent and looks like managing a simple enterprise in the network. The use of a Multi-Agent System (MAS) allows physical distribution of the decisional system, and procures a heterarchical organization structure with a decentralized control that guaranties the autonomy of each entity and the flexibility of the network.

description: Band offsets at semiconductor-oxide interfaces are determined through a scheme based on hybrid density functionals, which incorporate a fraction $α$ of Hartree-Fock exchange. For each bulk component, the fraction $α$ is tuned to reproduce the experimental band gap, and the conduction and valence band edges are then located with respect to a reference level. The lineup of the bulk reference levels is determined through an interface calculation, and shown to be almost independent of the fraction $α$. Application of this scheme to the Si-SiO$_2$, SiC-SiO$_2$, and Si-HfO$_2$ interfaces yields excellent agreement with experiment.

description: We perform extensive nonlinear numerical simulations of the spherical collapse of (charged) wavepackets onto a charged black hole within Einstein-Maxwell theory and in Einstein-Maxwell-scalar theory featuring nonminimal couplings and a spontaneous scalarization mechanism. We confirm that black holes in full-fledged Einstein-Maxwell theory cannot be overcharged past extremality and no naked singularities form, in agreement with the cosmic censorship conjecture. We show that naked singularities do not form even in Einstein-Maxwell-scalar theory, although it is possible to form scalarized black holes with charge above the Reissner-Nordström bound. We argue that charge and mass extraction due to superradiance at fully nonlinear level is crucial to bound the charge-to-mass ratio of the final black hole below extremality. We also discuss some "descalarization" mechanisms for scalarized black holes induced either by superradiance or by absorption of an opposite-charged wavepacket; in all cases the final state after descalarization is a subextremal Reissner-Nordström black hole.

description: Eyewitness testimony remains an important element in resolving criminal investigations. Despite a great deal of research on the subject, the understanding of the effects that witness gender might have on their testimony remains rather limited. The aim of the present study was to examine own-gender bias in recalling personal descriptions of perpetrators. Participants, who were invited to take part in the study, were told they were providing real-life assistance to criminal investigators and potentially helping them to verify hypotheses concerning an actual crime. The participants comprised 256 undergraduate volunteers, who were placed in one of the four groups. Each group observed one of the four crime scenarios that were varied only in terms of gender of either the victim or the perpetrator. All scenarios were designed as footage taken by a CCTV surveillance camera and involved two-minute videos of a staged assault and robbery. After seven days, participants completed a survey on the basis of which the accuracy and quantity of perpetrators’ personal descriptions were checked. Results revealed that participants’ accuracy of memory recall was modest. It was found that gender had a significant main effect on the accuracy of personal descriptions in all four research conditions, while an own-gender bias was also established. The highest accuracy of perpetrators’ personal descriptions was found when male participants reported details of a male perpetrator attacking a female victim, and when female participants described a female perpetrator attacking a female victim. The lowest accuracy was established when female participants described the male perpetrator molesting the male victim. However, no effect of gender on the amount of reported personal descriptions was found.

description: The purpose of this paper is to propose a new approach for the supply chain management. This approach is based on the virtual enterprise paradigm and the used of multi-agent concept. Each entity (like enterprise) is autonomous and must perform local and global goals in relation with its environment. The base component of our approach is a Virtual Enterprise Node (VEN). The supply chain is viewed as a set of tiers (corresponding to the levels of production), in which each partner of the supply chain (VEN) is in relation with several customers and suppliers. Each VEN belongs to one tier. The main customer gives global objectives (quantity, cost and delay) to the supply chain. The Mediator Agent (MA) is in charge to manage the supply chain in order to respect those objectives as global level. Those objectives are taking over to Negotiator Agent at the tier level (NAT). These two agents are only active if a perturbation occurs; otherwise information flows are only exchange between VENs. This architecture allows supply chains management which is completely transparent seen from simple enterprise of the supply chain. The used of Multi-Agent System (MAS) allows physical distribution of the decisional system. Moreover, the hierarchical organizational structure with a decentralized control guaranties, in the same time, the autonomy of each entity and the whole flexibility.
Fingerprints of Random Flows?

description: We consider the patterns formed by small rod-like objects advected by a random flow in two dimensions. An exact solution indicates that their direction field is non-singular. However, we find from simulations that the direction field of the rods does appear to exhibit singularities. First, ` scar lines' emerge where the rods abruptly change direction by $π$. Later, these scar lines become so narrow that they ` heal over' and disappear, but their ends remain as point singularities, which are of the same type as those seen in fingerprints. We give a theoretical explanation for these observations.

description: In recent years the theory of border collision bifurcations has been developed for piecewise smooth maps that are continuous across the border, and has been successfully applied to explain nonsmooth bifurcation phenomena in physical systems. However, many switching dynamical systems have been found to yield two-dimensional piecewise smooth maps that are discontinuous across the border. The theory for understanding the bifurcation phenomena in such systems is not available yet. In this paper we present the first approach to the problem of analysing and classifying the bifurcation phenomena in two-dimensional discontinuous maps, based on a piecewise linear approximation in the neighborhood of the border. We explain the bifurcations occurring in the static VAR compensator used in electrical power systems, using the theory developed in this paper. This theory may be applied similarly to other systems that yield two-dimensional discontinuous maps.

description: In his celebrated book "On Number and Games" (Academic Press, New-York, 1976), J.H. Conway introduced twelve versions of compound games. We analyze these twelve versions for the Node-Kayles game on paths. For usual disjunctive compound, Node-Kayles has been solved for a long time under normal play, while it is still unsolved under misère play. We thus focus on the ten remaining versions, leaving only one of them unsolved.

description: We investigate Hawking evaporation of a population of primordial black holes (PBHs) prior to Big Bang Nucleosynthesis (BBN) as a mechanism to achieve asymmetric reheating of two sectors coupled solely by gravity. While the visible sector is reheated by the inflaton or a modulus, the dark sector is reheated by PBHs. Compared to inflationary or modular reheating of both sectors, there are two advantages: $(i)$ inflaton or moduli mediated operators that can subsequently thermalize the dark sector with the visible sector are not relevant to the asymmetric reheating process; $(ii)$ the mass and abundance of the PBHs provide parametric control of the thermal history of the dark sector, and in particular the ratio of the temperatures of the two sectors. Asymmetric reheating with PBHs turns out to have a particularly rich dark sector phenomenology, which we explore using a single self-interacting real scalar field in the dark sector as a template. Four thermal histories, involving non-relativistic and relativistic dark matter (DM) at chemical equilibrium, followed by the presence or absence of cannibalism, are explored. These histories are then constrained by the observed relic abundance in the current Universe and the Bullet Cluster. The case where PBHs dominate the energy density of the Universe, and reheat both the visible as well as the dark sectors, is also treated in detail.

description: By means of a molecular model, we examine hybrid nematic films with antagonistic anchoring angles where one of the surfaces is in the strong anchoring regime. If anchoring at the other surface is weak, and in the absence of wetting by the isotropic phase, the anchoring transition may interact with the capillary isotropic-nematic transition in interesting ways. For general anchoring conditions on this surface we confirm the existence of the step-tilt, biaxial phase and the associated transition to the linear, constant-tilt-rotation, configuration. The step-like phase is connected with the bulk isotropic phase for increasing film thickness so that the latter transition is to be interpreted as the capillary isotropic-nematic transition. Finally, we suggest possible global surface phase diagrams.

description: When a sculptured thin film (STF), made of a metal and $\leq50$ nm thick, is used in lieu of a dense layer of metal in the Kretschmann configuration, experimental data for an STF comprising parallel tilted nanowires shows that a surface plasmon resonance (SPR) can still be excited. As the porosity of the chosen STF increases, experimental data and numerical simulations indicate the SPR dip with respect to the angle of incidence of the exciting plane wave widens and eventually disappears, leaving behind a a vestigial peak near the onset to the total-internal-reflection regime.
