description: This paper presents a novel deep learning-based approach for automatically vectorizing and synthesizing the clipart of man-made objects. Given a raster clipart image and its corresponding object category (e.g., airplanes), the proposed method sequentially generates new layers, each of which is composed of a new closed path filled with a single color. The final result is obtained by compositing all layers together into a vector clipart image that falls into the target category. The proposed approach is based on an iterative generative model that (i) decides whether to continue synthesizing a new layer and (ii) determines the geometry and appearance of the new layer. We formulated a joint loss function for training our generative model, including the shape similarity, symmetry, and local curve smoothness losses, as well as vector graphics rendering accuracy loss for synthesizing clipart recognizable by humans. We also introduced a collection of man-made object clipart, ClipNet, which is composed of closed-path layers, and two designed preprocessing tasks to clean up and enrich the original raw clipart. To validate the proposed approach, we conducted several experiments and demonstrated its ability to vectorize and synthesize various clipart categories. We envision that our generative model can facilitate efficient and intuitive clipart designs for novice users and graphic designers.

description: La violación de las más elementales reglas de la democracia y del estado de derecho, la tortura, la desaparición, el asesinato y las violaciones de género fueron prácticas corrientes de la historia de América Latina que vivió dictaduras cívico-militares en los años 70. Las transiciones políticas de los años 80-90 promovieron reformas institucionales para reforzar la democracia recuperada y procesos de justicia transicional en nombre de la verdad, memoria, justicia y reparación, las cuales se han tomado como modelo para el reciente proceso de paz en Colombia. El presente volumen recoge ensayos de estudiosos italianos y extranjeros que reconstruyen desde perpectivas socio-jurídicas estos procesos. Las formas de testimonio que se perfilan son obras diferentes de las de ‘literatura testimonial’ en el sentido estricto del término, porque surgen de las aulas judiciales y de los informes de las comisiones de verdad, y se imponen como verdades respaldadas por la actuación de la jurisprudencia, que las defiende de los asaltos del olvido y de la impunidad.

description: We present the first retrieval analysis of a substellar subdwarf, SDSS J125637.13-022452.4 (SDSS J1256-0224), using the Brewster retrieval code base. We find SDSS J1256-0224 is best fit by a cloud-free model with an ion (neutral H, H-, and electron) abundance corresponding to ion [Fe/H]=-1.5. However, this model is indistinguishable from a cloud-free model with ion [Fe/H]=-2.0 and a cloud-free model with ion Fe/H]=-1.5 assuming a subsolar carbon-to-oxygen ratio. We are able to constrain abundances for water, FeH, and CrH, with an inability to constrain any carbon-bearing species likely due to the low-metallicity of SDSS J1256-0224. We also present an updated spectral energy distribution (SED) and semi-empirical fundamental parameters. Our retrieval- and SED-based fundamental parameters agree with the Baraffe low-metallicity evolutionary models. From examining our "rejected" models (those with $Δ$BIC>45), we find that we are able to retrieve gas abundances consistent with those of our best-fitting model. We find the cloud in these poorer fitting "cloudy" models is either pushed to the bottom of the atmosphere or made optically thin.

description: ¿Cuál es la función del testigo frente a las políticas del estado? ¿Cuáles son las instancias que definen la producción y recepción de su palabra? ¿Cómo visibilizar las huellas del testimonio en una realidad amnésica, cada vez más condicionada por el mercado? En la encrucijada entre el territorio jurídico-político y literario, los textos aquí reunidos se proponen desvelar el ‘secreto’ de la praxis testimonial, iluminando una serie de obras narrativas que describen los contextos chilenos entre el 1973, año tristemente célebre por el comienzo de la dictadura, y el 2015. La vozde los testigos (Hernán Valdés, Jorge Montealegre, Rolando Carrasco), la reparación autobiográfica del dolor (Guillermo Núñez) y la traducción en palabra poética de la resistencia al horror y la violencia (Raúl Zurita, Diamela Eltit) se suman a la mediación de la memoria por parte de actores secundarios que, en el proceso de ‘narrativización’, exponen el pasado a nuevas instancias discursivas, reposicionando y redefiniendo sus contornos (Carlos Franz, Fátima Sime, Lucía Guerra). El conjunto de ensayos refleja una aproximación a lo testimonial como ejercicio de búsqueda siempre inacabado, que se realiza en la apertura hacia el otro, en la asunción de sus instancias, en la inclusión, siempre inacabada, en su universo.

description: 60. Erebidae - quadrifine noctuoids As currently defined, this is a very large assemblage of noctuoid moths, with an enormous diversity in size, facies, ecology and biology. Although relatively well-supported as a natural group by molecular and morphological data, the phylogeny within this group is still in its infancy – many relationships within the Erebidae are still poorly resolved, to say nothing of tropical groups that still await discovery and/or phylogenetic placement. There are however also several strongly supported groups now included within the Erebidae, such as the Lymantriinae, Arctiinae, and Herminiinae. The Erebidae as currently defined may well be split into a number of families in the future. It is diffi cult to draw generalizations on such a hyper-diverse group, and brief introductory sections are limited to subfamilies here. As it is currently constituted, Erebidae is represented by 124 species in AB. 60.1. Lymantriinae – tussock moths Mostly medium-sized (30–80 mm wingspan) moths with robust bodies. Wing pattern and color is usually drab, and several genera have wingless (Orgyia) or flightless (Gynaephora, some Lymantria) females. Th e subfamily Lymantriinae is thought to be closely related to the Arctiinae (both groups have hairy larvae), Aganainae and Herminiinae. Like the Arctiinae, the most recent systematic arrangement of the Noctuoidea places the Lymantriinae as a subfamily of the Erebidae rather than as a separate family (Lafontaine and Schmidt in press). Larvae are predominantly arboreal, feeding on both deciduous and coniferous woody plants. Many species are host generalists, and a relatively high proportion of this subfamily are forest pests, most notably the Gypsy Moth (Lymantria dispar), the Satin Moth (Leucoma salicis) and the Douglas-fir Tussock Moth (Orgyia pseudotsugata). Approximately 2500 species of Lymantriinae are known worldwide, with diversity centered in the Old World tropics: only about 200 species are known from the New World. Th irty-two species occur in North America, nine of which are reported from AB. Ferguson (1978) treated all of the North American Lymantriinae.

description: Il volume raccoglie saggi dedicati alla tradizione gnomica nelle letterature germaniche medievali. Dopo un primo contributo che illustra i principali filoni della ricerca fraseologica e paremiologica, le trattazioni approfondiscono l’elemento didascalico affrontando questioni linguistiche, letterarie e socio-culturali in diversi generi testuali, alcuni orientati a contenuti gnomici, come indovinelli, codici giuridici, raccolte di massime e proverbi, altri di carattere epico, elegiaco o mistico. Gli studi toccano le aree di lingua inglese, tedesca, nederlandese e frisone, nei periodi antico e medio, con contatti e riferimenti anche all’area nordica. I numerosi microtesti gnomici mostrano una grande capacità di diffusione e penetrazione in diversi ambiti culturali, sia circolando singolarmente che inseriti in testi più ampi. Stilemi e contenuti ricorrono in tutte le aree linguistiche europee, evidenziando lo stretto legame fra il mondo germanico e la tradizione sapienziale classica e biblico-cristiana.

Bodies that Bleed. Metamorphosis in Angela Carter’s Fairy Tales
Creators: name: Pasolini, Anna
Publisher: name: di/segni
Year: 2017

description: This work aims to develop new readings of the poetics and the politics of Angela Carter’s The Bloody Chamber and Other Stories (1979) in the light of the bodily metamorphoses represented in the fairy tales. Metamorphic processes can be said to inform the stories of the collection both in a thematic and a stylistic perspective and address the need to rethink human experience altogether, especially as regards heterosexual relationships and power distribution between the sexes. By exhibiting the body and its changes in texts where it is traditionally concealed or treated as a natural essence, Carter foregrounds the powerful potential of metamorphosis – as a concept, a topic, a structuring and guiding principle, and as a proposed model – in order to expose and challenge patriarchal myths and discourses, which slow down or even prevent the progressive empowerment of women’s conditions and positions within society (in the Seventies as well as today). Carter’s creativity and commitment are engaged in a productive dialogue with some contemporary feminist philosophers, to show how and why her fairy tales and their transformative potential can be – once again – signified anew.

description: We study the time evolution of two electron spin states in a double quantum-dot system, which includes a nearby quantum point contact (QPC) as a measurement device. We obtain that the QPC measurement induced decoherence is in time scales of microsecond. We also find that the enhanced QPC measurement will trap the system in its initial spin states, which is consistent with quantum Zeno effect.

Basti pensare alle allegre crapule di Falstaff, il grasso cinghiale divorato dai triumviri di Antony and Cleopatra, il ricco ma fugace banchetto che appena s’intravede in The Tempest, oltre alle numerose altre scene in cui il cibo è metafora importante e portante dei molteplici sensi del testo. Nella cucina del bardo si sono inoltre formati autori che in modo cannibalesco hanno attinto a piene mani a ingredienti e sapori per cucinare testi inediti, succulenti o rivoltanti. Dai lecca-lecca dei burlesque ottocenteschi, passando per il grano dei Coriolanus di Bertold Brecht e Günter Grass, gli ingredienti shakespeariani lievitano misteriosamente e in modi sorprendenti nella dieta mediterranea di Franco Zeffirelli e Kenneth Branagh oltre che negli allegri brindisi del Falstaff verdiano.

description: This volume is the final output of a project started in 2013 on the occasion of the fortieth anniversary of the Scandinavian Section of the University of Milan. A group of scholars working on different European and non-European cultural and literary traditions come together here to discuss the relationships between their areas of study and the Nordic countries. The range of the contributions expands over time and space, from the Middle Ages to the present day, from Poland in the east to the United States in the west, across various European countries. Through various kinds of expertise and different perspectives, this intercultural discourse deals with diverse themes, including the perception of Nordic culture(s) by foreign writers as well as the image of other cultures in Scandinavian works. In particular, the literary and cultural interchange of models and ideas between the North and other areas is investigated in a number of essays devoted to numerous authors, including, among others, Klaus Böldl, Carmen de Burgos, Carlo Emilio Gadda, Gerhart Hauptmann, Henrik Ibsen, Stieg Larsson, Carl von Linné, Rainer Maria Rilke, J.D. Salinger, Henryk Sienkiewicz, Mme de Staël, August Strindberg, and Tomas Tranströmer.

A Spectroscopic Survey for Omega Centauri Members at and beyond the Cluster Tidal Radius

description: We have used the two-degree field (2dF) multi-fibre spectrograph of the Anglo-Australian Telescope to search for candidate members of the unusual globular cluster omega Centauri at and beyond the cluster tidal radius. Velocities with an accuracy of ~10 kms-1 were obtained for 4105 stars selected to lie in the vicinity of the lower giant branch in the cluster colour-magnitude diagram and which cover an area on the sky of ~2.4x3.9 deg2 centered on the cluster. Within the velocity interval 190-270 kms-1, the cluster member candidates have a steeply declining surface density distribution consistent with the adopted tidal radius of 57`. For stars in the sample beyond the tidal radius, an analysis of line-strengths from the spectra, as well as radial velocities, identifies only six stars as possible candidates for extra-tidal association with the cluster. If all six of these stars are indeed related to the cluster, then a maximum of 0.7 +/- 0.2 per cent of the total cluster mass is contained in the region between one and two tidal radii. Given this limit, we conclude that there is no compelling evidence for any significant extra-tidal population in omega Cen. The effects of tidal shocks on the outer parts of the cluster are consistent with this limit. Theories for the origin of omega Cen frequently suggest that the cluster is the former nucleus of a tidally stripped dwarf galaxy. Our results require that the stripping process must have been largely complete at early epochs, consistent with dynamical models of the process. The stripped former dwarf galaxy stars are therefore now widely distributed around the Galaxy.

description: The sum gate is the canonical two-mode gate for universal quantum computation based on continuous quantum variables. It represents the natural analogue to a qubit C-NOT gate. In addition, the continuous-variable gate describes a quantum nondemolition (QND) interaction between the quadrature components of two light fields. We experimentally demonstrate a QND sum gate, employing the scheme by R. Filip, P. Marek, and U.L. Andersen [\pra {\bf 71}, 042308 (2005)], solely based on offline squeezed states, homodyne measurements, and feedforward. The results are verified by simultaneously satisfying the criteria for QND measurements in both conjugate quadratures.

description: Understanding tourist visitation patterns is crucial for decision makers in order to create smart tourism industry. A growing body of tourism research uses geo-location data in order to better understand tourism demand. In this paper, we present a new approach based on a market basket analysis. This approach uses geo-location data shared by tourists on tourism platforms in order to bundle the range of available tourism services and understand which experiences are consumed together. The approach was tested on the case of Vienna, Austria. Based on our analyses we argue that the proposed approach has potential for use at the destination level and provides relevant information on tourism demand patterns important for smart tourism decision-making.

One-loop masses of open-string scalar fields in String Theory

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In phenomenological models with D-branes, there are in general open-string massless scalar fields, in addition to closed-string massless moduli fields corresponding to the compactification. It is interesting to focus on the fate of such scalar fields in models with broken supersymmetry, because no symmetry forbids their masses. The one-loop effect may give non-zero masses to them, and in some cases mass squared may become negative, which means the radiative gauge symmetry breaking. In this article we investigate and propose a simple method for calculating the one-loop corrections using the boundary state formalism. There are two categories of massless open-string scalar fields. One consists the gauge potential fields corresponding to compactified directions, which can be understood as scalar fields in uncompactified space-time (related with Wilson line degrees of freedom). The other consists "gauge potential fields" corresponding to transverse directions of D-brane, which emerge as scalar fields in D-brane world-volume (related with brane moduli fields). The D-brane boundary states with constant backgrounds of these scalar fields are constructed, and one-loop scalar masses are calculated in the closed string picture. Explicit calculations are given in the following four concrete models: one D25-brane with a circle compactification in bosonic string theory, one D9-brane with a circle compactification in superstring theory, D3-branes at a supersymmetric C^3/Z_3 orbifold singularity, and a model of brane supersymmetry breaking with D3-branes and anti-D7-branes at a supersymmetric C^3/Z_3 orbifold singularity. We show that the sign of the mass squared has a strong correlation with the sign of the related open-string one-loop vacuum amplitude.

La conseguenza di una metamorfosi. Topoi postmoderni nella poesia di Luis García Montero
Creators: name: Calabrese, Giuliana
Publisher: name: di/segni
Year: 2016

description: Nell’ultimo trentennio un versante della poesia spagnola, identificabile con la generalizzante etichetta di ‘poesia dell’esperienza’ e rappresentata al massimo grado dal poeta Luis García Montero, si è fatta carico di un impegno civico spesso passato in secondo piano a causa della semplicistica identificazione tra i temi poetici esperienziali e la biografia empirica degli autori. Per approfondire lo studio dell’impegno racchiuso nei versi di García Montero si rivela utile l’analisi dei topoi poetici a cui il granadino ricorre e che rielabora in tutte le sue raccolte, recuperando inoltre le teorie sul postmoderno proposte da Habermas e che la poesía de la experiencia ha reso proprie, grazie anche al magistero di Juan Carlos Rodríguez. García Montero, infatti, riprendendo i topoi codificati dalla tradizione e rielaborandoli alla luce di una necessaria interpretazione storica della contingenza, dà vita a un sistema poetico che dota il lettore di una profonda coscienza di libertà e autodeterminazione. A cominciare dallo studio delle ricorrenti immagini dell’io poetico, l’analisi si sposta poi allo spazio letterario creato da García Montero che affonda le radici nell’essenza della prima persona, si estende alla rappresentazione corporea e si espande definitivamente alla costruzione delle città letterarie. L’analisi testuale dimostra che le immagini letterarie della tradizione vengono trasformate da Montero per suggerire la necessità di riappropriazione per l’uomo contemporaneo – se pervaso dallo spirito democratico – di un nuovo spazio pubblico, da istituire nella poesia quando quello concreto viene meno.

description: The underlying plasma composition of relativistic extragalactic jets remains largely unknown. Relativistic magnetohydrodynamic (RMHD) models are able to reproduce many of the observed macroscopic features of these outflows. The nonthermal synchrotron emission detected by very long baseline interferometric (VLBI) arrays, however, is a by-product of the kinetic-scale physics occurring within the jet, physics that is not modeled directly in most RMHD codes. This paper attempts to discern the radiative differences between distinct plasma compositions within relativistic jets using small-scale 3D relativistic particle-in-cell (PIC) simulations. We generate full Stokes imaging of two PIC jet simulations, one in which the jet is composed of an electron-proton ($e^{-}$-$p^{+}$) plasma (i.e., a normal plasma jet), and the other in which the jet is composed of an electron-positron ($e^{-}$-$e^{+}$) plasma (i.e., a pair plasma jet). We examined the differences in the morphology and intensity of the linear polarization (LP) and circular polarization (CP) emanating from these two jet simulations. We find that the fractional level of CP emanating from the $e^{-}$-$p^{+}$ plasma jet is orders of magnitude larger than the level emanating from an $e^{-}$-$e^{+}$ plasma jet of a similar speed and magnetic field strength. In addition, we find that the morphology of both the linearly and circularly polarized synchrotron emission is distinct between the two jet compositions. We also demonstrate the importance of slow-light interpolation and we highlight the effect that a finite light-crossing time has on the resultant polarization when ray-tracing through relativistic plasma.

description: The massive galaxies in the young universe, ten billion years ago, formed stars at surprising intensities. Although this is commonly attributed to violent mergers, the properties of many of these galaxies are incompatible with such events, showing gas-rich, clumpy, extended rotating disks not dominated by spheroids (Genzel et al. 2006, 2008). Cosmological simulations and clustering theory are used to explore how these galaxies acquired their gas. Here we report that they are stream-fed galaxies, formed from steady, narrow, cold gas streams that penetrate the shock-heated media of massive dark matter haloes (Dekel & Birnboim 2006; Keres et al. 2005). A comparison with the observed abundance of star-forming galaxies implies that most of the input gas must rapidly convert to stars. One-third of the stream mass is in gas clumps leading to mergers of mass ratio greater than 1:10, and the rest is in smoother flows. With a merger duy cycle of 0.1, three-quarters of the galaxies forming stars at a given rate are fed by smooth streams. The rarer, submillimetre galaxies that form stars even more intensely are largely merger-induced starbursts. Unlike destructive mergers, the streams are likely to keep the rotating disk configuration intact, although turbulent and broken into giant star-forming clumps that merge into a central spheroid (Noguchi 1999; Genzel et al. 2008, Elmegreen, Bournaud & Elmegreen 2008, Dekel, Sari & Ceverino 2009). This stream-driven scenario for the formation of disks and spheroids is an alternative to the merger picture.

description: In British Columbia, adult basic education (ABE) has evolved into a significant program area on the verge of gaining acceptance as a legitimate and important part of the public education system. If the resources currently committed to these programs are to be solidified and increased, it is imperative the present program impact be measured, the needs, resources, processes and outcomes be articulated and the benefits of increased programming be predicted. This is best accomplished through effective use of program evaluation. The field of program evaluation is characterized by a lack of well developed theory, a series of complex models, an absence of methodology and an abundance of designs and checklists which are not tied to a sound theory or model. The purpose of this study was threefold. Firstly, it reviewed the extant models and methodologies for the evaluation of adult education programs. Secondly, a methodology for evaluating innovative, ABE programs was developed. Finally, the methodology was used to guide an evaluation of an adult basic education project conducted by a British Columbia college, evaluated accomplished few of methodology provided a useful guide the evaluation process. While the project being its stated objectives, the and flexible structure to It is hoped that this methodology will be field tested on a variety of ABE programs and that additional research will result in an even more sophisticated methodology designed to strengthen the ties between the best theories and models and the field of practice.

description: With the outbreak of COVID-19 in the spring of 2020, under the guidance of “school closure, non-stop schooling” by China’s Ministry of Education (MOE), China’s colleges and universities have made full use of online resources and teaching platforms to adopt a variety of teaching modes, i.e. traditional teaching mode combined with the Internet, offline teaching combined with online teaching, and live webcast teaching combined with mobile teaching. This paper aims to analyze the teaching modes of college English in the period of epidemic prevention and control, so as to provide more diversified options for college English teaching after the epidemic.

description: We discuss the structure of beta functions as determined by the recursive nature of Dyson--Schwinger equations turned into an analysis of ordinary differential equations, with particular emphasis given to quantum electrodynamics. In particular we determine when a separatrix for solutions to such ODEs exists and clarify the existence of Landau poles beyond perturbation theory. Both are determined in terms of explicit conditions on the asymptotics for the growth of skeleton graphs.

description: Non-spherical structure in massive stars at the point of iron core collapse can have a qualitative impact on the properties of the ensuing core-collapse supernova explosions and the multi-messenger signals they produce. Strong perturbations can aid successful explosions by strengthening turbulence in the post-shock region. Here, we report on a set of $4π$ 3D hydrodynamic simulations of O- and Si-shell burning in massive star models of varied initial masses using MESA and the FLASH simulation framework. We evolve four separate 3D models for roughly the final ten minutes prior to, and including, iron core collapse. We consider initial 1D MESA models with masses of 14-, 20-, and 25 $M_{\odot}$ to survey a range of O/Si shell density and compositional configurations. We characterize the convective shells in our 3D models and compare them to the corresponding 1D models. In general, we find that the angle-average convective speeds in our 3D simulations near collapse are three to four times larger than the convective speeds predicted by MESA at the same epoch for our chosen mixing length parameter of $α_{\rm{MLT}}=1.5$. In three of our simulations, we observe significant power in the spherical harmonic decomposition of the radial velocity field at harmonic indices of $\ell=1-3$ near collapse. Our results suggest that large-scale modes are common in massive stars near collapse and should be considered a key aspect of pre-supernova progenitor models.

Quantum ratchet control - harvesting on Landau-Zener transitions

description: We control the current of a single particle quantum ratchet by designing ramping schemes for experimentally accessible control parameters. We harvest on Landau-Zener transitions between Floquet states. Adiabatic and diabatic ramping allow to control the resulting directed transport. We find strong changes of the current in the adiabatic regime. Simple loops in control parameter space with alternating adiabatic and diabatic ramping are proposed. We obtain also current reversal. Full desymmetrization of the quantum ratchet increases the critical ramping speed which separates the adiabatic from the diabatic regime.

description: Part of a collection of letters from award-winning British poet and scholar Kathleen Raine to Percy Jarrett, owner of the dealership Philobiblion which specialized in literary books and manuscripts. Most of the letters discuss the negotiation of sales of Raine’s manuscript material (of which Irvine Library at the University of California was the primary buyer), the periodical Temenos, that Raine co-founded; and Jarret’s son-in law Robin Skelton, who was a poet and Professor of English Literature at the University of Victoria. In this letter Raine writes about Temenos and her life at present.

Publisher: name: di/segni
Year: 2016

description: Il volume è dedicato al rapporto tra alimentazione, cultura e società nell’Africa contemporanea. Ricercatori di diverse discipline (geografia, letteratura, antropologia, economia) si confrontano con operatori della cooperazione internazionale per approfondire le criticità nell’accesso al cibo in Africa e analizzare le risorse materiali e immateriali che le società africane attivano in questo settore. Una particolare attenzione è dedicata alle strategie delle comunità locali in ambito agricolo e alimentare: in un contesto globale caratterizzato da forti squilibri, la dimensione locale costituisce un’importante opportunità per garantire un’alimentazione sufficiente e di qualità, conservando e valorizzando l’ambiente e le culture africane.

L’Antartide nell’immaginario Inglese
Creators: name: Brazzelli, Nicoletta
Publisher: name: di/segni
Year: 2016

description: Spazio geografico e rappresentazione letteraria Mettendo in rilievo le contiguità disciplinari esistenti fra studi territoriali e studi letterari, il volume esamina le rappresentazioni dell’Antartide in una serie di narrazioni in lingua inglese che costituiscono un ricco repertorio di linguaggi dell’immaginario geografico. Il continente di ghiaccio si è infatti configurato come uno spazio vuoto che, nel corso del tempo, ha coinciso con il desiderio di pervenire alla conoscenza del mondo naturale, prestandosi a un’appropriazione ‘coloniale’ non tanto in senso fisico e materiale quanto in termini verbali e iconografici. Nella cultura inglese lo spazio dell’estremo Sud ha ispirato una molteplicità di racconti, dalle cronache degli esploratori nei primi decenni del Novecento alle narrazioni femminili e distopiche contemporanee. Dal capitano Scott a Beryl Bainbridge, da Cherry-Garrard alla fantascienza, si è creata una ‘psicotopografia’ antartica in cui si riflettono il fascino e il mistero di un luogo anomalo, profondamente ancorato alla dimensione immaginativa.

description: We study systems with local vibrating potentials, one-dimensional single and double wells and the tight-binding 1D model with single vibrating site. In general, these systems transmit, or reflect particles inelastically, with absorption or emission of several frequency quanta. Nevertheless, we have found that at some conditions these systems can perfectly and elastically reflect electrons. This high-frequency "blockade" give rise to unique possibility of near-ideal localization of electron with the energy lying on the background of continuous energy spectrum. We discuss different consequences of this statement.
