description: Достоверная частота парауретральных кист до сих пор неизвестна из-за отсутствия специфических симптомов. Тяжесть симптомов при парауретральных кистах не всегда коррелирует с размерами кистозного образования. В статье приведен случай клинического наблюдения хирургического лечения парауретральной кисты у женщины репродуктивного возраста. Данное наблюдение демонстрирует, что в лечении этого заболевания приоритет остается за хирургическими методами. Диагностика и лечение парауретральных кист требуют внимания специалистов разного профиля: врача общей практики, гинеколога, уролога, хирурга. На сегодняшний день не приветствуется пассивная тактика лечения в виде наблюдения пациентки с бессимптомным течением парауретральной кисты. Выжидательная тактика ведения этого заболевания приводит к серьезным осложнениям, таким как инфицирование содержимого кисты, образование парауретрального абсцесса и т.д.

description: Нейтрофильный лейкоцитоз со сдвигом влево до миелоцитов нередко выявляется во II-III триместрах физиологической беременности. Интерпретация мелоидных реакций представляет трудности для врачей. Неправильная трактовка общеклинического анализа крови ведет к ненужному скринингу и назначению антибактериальной терапии без показаний. В статье приведены факторы риска развития лейкемоидных реакций с миелоцитарным сдвигом у беременных, высказано предположение о ведущей роли гормонов и цитокинов плаценты в их формировании. Описан казуистический случай развития гестационной миелоидной реакции у пациентки с ремиссией острого лимфобластного лейкоза, обсуждена ее дифференциальная диагностика, даны рекомендации по ведению женщин с этой особенностью нормального течения беременности.

description: В России рак молочной железы занимает лидирующую позицию среди злокачественных новообразований у женского населения. В настоящее время отмечается тенденция к увеличению числа больных раком молочной железы молодого возраста. В связи с этим повышаются требования к качеству жизни пациентов, в частности эстетическим результатам проведенного специального лечения. Подобная тенденция в настоящее время способствует внедрению методов реконструктивной и пластической хирургии в онкомаммологическую практику. Несмотря на увеличение частоты органосохраняющих операций, радикальная мастэктомия остается одним из основных методом лечения при наличии противопоказаний к проведению радикальной резекции молочной железы, что, в конечном итоге, оказывается для женщины тяжелой психоэмоциональной травмой. Помимо прочего, реконструктивно-пластические операции занимают одно из главных мест в реабилитации больных раком молочной железы. Одним из наиболее распространенных методов реконструкции молочной железы, после радиальной мастэктомии, является двухэтапная операция с установкой тканевого расширителя на первом этапе. Общеизвестно, что радиотерапия является важным компонентом комбинированного и комплексного лечения рака молочной железы, повышающим локорегиональный контроль опухолевого процесса, и, в целом, выживаемость пациенток. В то же время отмечено, что проведение радиотерапии у пациенток с установленным тканевым расширителем негативно влияет на результаты реконструкции, увеличивая вероятность развития отсроченных осложнений в виде капсульных контрактур различных степеней тяжести, протрузий и т.п. Однако, несмотря на это, наличие тканевого расширителя не является прямым противопоказанием к проведению радиотерапии. В настоящей статье кратко представлен ряд данных по радиотерапии рака молочной железы у пациенток в процессе двухэтапной реконструкции молочной железы после радикальной мастэктомии.

description: We present 12.8 microns images of the core of NGC 1068 obtained with the BURST mode of the VLT/VISIR. We trace structures under the diffraction limit of one UT and we investigate the link between dust in the vicinity of the central engine of NGC 1068, recently resolved by interferometry with MIDI, and more extended structures. This step is mandatory for a multi-scale understanding of the sources of mid-infrared emission in AGNs. A speckle processing of VISIR BURST mode images was performed to extract very low spatial-frequency visibilities, first considering the full field of VISIR BURST mode images and then limiting it to the mask used for the acquisition of MIDI data. Extracted visibilities are reproduced with a multi-component model. We identify two major sources of emission: one compact < 85 mas, associated with the dusty torus, and an elliptical one, (< 140) mas x 1187 mas at P.A.=-4 degrees from N to E. This is consistent with previous deconvolution processes. The combination with MIDI data reveals the close environment of the dusty torus to contribute to about 83 percent of the MIR flux seen by MIDI. This strong contribution has to be considered in modeling long baseline interferometric data. It must be related to the NS elongated component which is thought to originate from individually unresolved dusty clouds and is located inside the ionization cone. Low temperatures of the dusty torus are not challenged, emphasizing the scenarios of clumpy torus.

description: Hard-to-cut materials and composites have been progressively replacing aluminum in aircraft components. These materials may be arranged into spars, ribs, skins and other structural parts, thus demanding manufacturing in a single operation, such as drilling. When these materials are stacked together, achieving surface finishing and dimensional requirements becomes more difficult due to the dissimilar machining behavior. This study conducted an experimental investigation on the drilling process of aluminum, titanium and stainless steel metal plates in a multi-layered arrangement. Tests were done on individual materials as well as on stacked plates in order to allow for comparison of results. Experimental runs consisted of using a design of experiments (DOE) approach for the following factors: cutting speed, feed per revolution and different commercial drills. Investigated responses for the holes were: diameter, circularity, cylindricity, thrust force, roughness, chip, and bum formation. Statistical analysis of results by means of analysis of variance (ANOVA) determined the contribution of the different factors on hole diameter, circularity and cylindricity. Results allow concluding that applying one-step drilling on materials separately can induce positive results. On other hand, design and manufacturing constraints limit the stacking sequence of layers, which may directly affect and even drastically the surface finishing and dimensional quality results. Therefore, further investigation on alternate drilling methods is suggested for future developments, which could improve quality to higher standards.

description: We experimentally demonstrate the efficient generation of circularly polarized pulses tunable from the vacuum to deep ultraviolet (160-380 nm) through resonant dispersive wave emission from optical solitons in a gas-filled hollow capillary fiber. In the deep ultraviolet we measure up to 13 microjoule of pulse energy, and from numerical simulations, we estimate the shortest output pulse duration to be 8.5 fs. We also experimentally verify that simply scaling the pulse energy by 3/2 between linearly and circularly polarized pumping closely reproduces the soliton and dispersive wave dynamics. Based on previous results with linearly polarized self-compression and resonant dispersive wave emission, we expect our technique to be extended to produce circularly polarized few-fs pulses further into the vacuum ultraviolet, and few to sub-fs circularly polarized pulses in the near-infrared.

description: Critical behavior of the Ising model is investigated at the center of large scale finite size systems, where the lattice is represented as the tiling of pentagons. The system is on the hyperbolic plane, and the recursive structure of the lattice makes it possible to apply the corner transfer matrix renormalization group method. From the calculated nearest neighbor spin correlation function and the spontaneous magnetization, it is concluded that the phase transition of this model is mean-field like. One parameter deformation of the corner Hamiltonian on the hyperbolic plane is discussed.

description: Brown dwarfs are essential targets for understanding planetary and sub-stellar atmospheres across a wide range of thermal and chemical conditions. As surveys continue to probe ever deeper, and as observing capabilities continue to improve, the number of known Y dwarfs -- the coldest class of sub-stellar objects, with effective temperatures below about 600 K -- is rapidly growing. Critically, this class of ultra-cool objects has atmospheric conditions that overlap with Solar System worlds and, as a result, tools and ideas developed from studying Earth, Jupiter, Saturn and other nearby worlds are well-suited for application to sub-stellar atmospheres. To that end, we developed a one-dimensional (vertical) atmospheric structure model for ultra-cool objects that includes moist adiabatic convection, as this is an important process for many Solar System planets. Application of this model across a range of effective temperatures (350, 300, 250, 200 K), metallicities ([M/H] of 0.0, 0.5, 0.7, 1.5), and gravities (log $g$ of 4.0, 4.5, 4.7, 5.0) demonstrates strong impacts of water latent heat release on simulated temperature-pressure profiles. At the highest metallicities, water vapor mixing ratios reach an Earth-like 3%, with associated major alterations to the thermal structure in the atmospheric regions where water condenses. Spectroscopic and photometric signatures of metallicity and moist convection should be readily detectable at near- and mid-infrared wavelengths, especially with James Webb Space Telescope observations, and can help indicate the formation history of an object.

description: An important step in the calculation of the triply graded link homology theory of Khovanov and Rozansky is the determination of the Hochschild homology of Soergel bimodules for SL(n). We present a geometric model for this Hochschild homology for any simple group G, as equivariant intersection homology of B x B-orbit closures in G. We show that, in type A these orbit closures are equivariantly formal for the conjugation T-action. We use this fact to show that in the case where the corresponding orbit closure is smooth, this Hochschild homology is an exterior algebra over a polynomial ring on generators whose degree is explicitly determined by the geometry of the orbit closure, and describe its Hilbert series, proving a conjecture of Jacob Rasmussen.

description: Abstract

In an age of information abundance, the ability to accurately recall and apply factual knowledge is paramount. However, traditional learning methods often fall short in fostering robust memory retention and efficient knowledge transfer. This paper introduces the Single-Line Training FACT (SLTF) framework, a novel approach designed to enhance human factual recall by presenting information in a concise, structured, and easily memorable format. The SLTF framework leverages key principles from cognitive science and information architecture to optimize knowledge organization and retrieval. Each SLTF encapsulates a single fact, structured into key features, context, and examples, facilitating efficient learning and recall. This paper explores the origins, principles, and potential applications of the SLTF framework, highlighting its potential to empower individuals and contribute to the pursuit of human Total Recall.

The Single-Line Training FACT (SLTF) Framework is a novel approach to enhancing human memory and knowledge retention by presenting information in a concise, structured, and easily memorable format. Each SLTF encapsulates a single fact, organized into key features, context, and examples, facilitating efficient learning and recall. The framework also incorporates “intelligent tagging”(Billions, Knight) with UUIDs and group identifiers for easy organization and retrieval. SLTFs can be represented in JSON format for structured storage and exchange, and their structure is formally defined using an EBNF-like notation for clarity and programmatic/machine/AI validation.

description: The bright blazar OJ 287 is the best-known candidate for hosting a supermassive black hole binary system. It inspirals due to the emission of nanohertz gravitational waves (GWs). Observations of historical and predicted quasi-periodic high-brightness flares in its century-long optical lightcurve, allow us to determine the orbital parameters associated with the binary black hole (BBH) central engine. In contrast, the radio jet of OJ 287 has been covered with Very Long Baseline Interferometry (VLBI) observations for only about $30$ years and these observations reveal that the position angle (PA) of the jet exhibits temporal variations at both millimetre and centimetre wavelengths. Here we associate the observed PA variations in OJ 287 with the precession of its radio jet. In our model, the evolution of the jet direction can be associated either with the primary black hole (BH) spin evolution or with the precession of the angular momentum direction of the inner region of the accretion disc. Our Bayesian analysis shows that the BBH central engine model, primarily developed from optical observations, can also broadly explain the observed temporal variations in the radio jet of OJ 287 at frequencies of 86, 43, and 15 GHz. Ongoing Global mm-VLBI Array (GMVA) observations of OJ 287 have the potential to verify our predictions for the evolution of its $86$ GHz PA values. Additionally, thanks to the extremely high angular resolution that the Event Horizon Telescope (EHT) can provide, we explore the possibility to test our BBH model through the detection of the jet in the secondary black hole.

Accessibility of broadcast archives in Canada
Creators: name: Norman, Jan M.
Publisher: name: University of British Columbia
Year: 2010

description: Canada's broadcasting industry has a rich history and yet by their own admission, Canadian archivists once overlooked the value of broadcast documentation. This thesis explores the many issues which govern the acquisition, appraisal and description of broadcast records and the relevance of these issues to access and use. Because archivists have frequently discussed access to textual material, this exposition focuses on the special media records produced by the broadcasting industry: film, videotape and sound recordings. This discussion reviews the problems associated with the development of an acquisition strategy for these records and outlines the development of appraisal criteria which recognize their intellectual, artistic and sociological content. The descriptive practices preferred by archivists working with broadcast material are evaluated to determine whether they actually respond to users needs. The physical characteristics which influence access and use are also reviewed. The proposed revisions to Canada's Copyright Act are examined and the implications for access and use are noted. Finally, throughout this exposition attention is given to the financial obligations associated with the preservation and use of these records. This study is based on an examination of Canadian, American and European archival literature and the discussion of each archival function incorporates the theoretical views and practical experiences of various archival institutions. The study concludes that to facilitate accessibility and use, repositories should more thoroughly investigate the requirements of broadcast records and agree to participate in preserving these documents based on a sound assessment of the impact such involvement has on operational resources.
Quasinormal Modes of Black Holes with Non-Linear-Electrodynamic sources in Rastall Gravity

description: One of the notable modifications of General Relativity (GR) is the Rastall gravity. We have studied the polarization modes of Gravitational Waves (GWs) in this gravity. It is found that at a very far distance away from the source of GWs, Rastall gravity behaves identically to GR. That is, we get only two massless tensor polarization modes of GWs in the theory. Afterwards, we have extended our study to quasinormal modes of black holes in Rastall gravity in presence of non-linear electrodynamic sources. Here the impacts of cosmological field, dust field, phantom field, quintessence field and radiation field on the quasinormal modes in presence of electrodynamic sources have been investigated. Apart from this, we have also checked the dependency of quasinormal modes with the Rastall parameter $λ$, black hole structural constant $N_s$ and charge of the black hole $Q$. The study shows that the quasinormal modes corresponding to the black hole with non-linear electrodynamic sources show significant deviations from a general charged black hole in Rastall gravity under certain conditions. Further, the behaviour of black holes and hence the quasinormal modes depend on the type of surrounding field considered.

description: Цель исследования. Изучить взаимосвязи склеростина крови с клиническими параметрами и его влияние на вероятность обнаружения сердечно-сосудистой кальцификации у больных с ХБП С5Д. Материал и методы. Исследование одномоментное, когортное с включением 84 больных с ХБП 5Д стадии, получавших терапию гемодиализом, из них 40 (47,6,%) пациентов женского пола и 44 (52,4%) - мужского пола. Средний возраст составил 55,6±14,9 лет. Обследование включало, помимо рутинных исследований, проведение эхокардиоскопии с оценкой кальцификации клапанов сердца, рентгенографии живота в боковой проекции с оценкой кальцификации аорты, анализ показателей, характеризующих фосфорно-кальциевых обмен (уровни сывороточных склеростина, 1,25(ОН)Д, FGF-23, A-klotho, ПТГ, Р и Са крови). Результаты. Было показано, что уровень склеростина выше у лиц пожилого возраста, а также тех, кто имеет признаки гипопротеинемии и гипоальбуминемии, косвенно свидетельствующие о наличии белковоэнергетической недостаточности. Имеется связь склеростина крови с FGF-23 и Alpha-klotho. С точки зрения вероятного влияния на процессы сердечно-сосудистой кальцификации данная связь показывает свою однонаправленность. Было показано, что повышение уровня склеростина в крови ассоциируется с риском обнаружения признаков сердечно-сосудистой кальцификации. Более того, показано, что чем выше уровень склеростина в крови, тем выраженней степень этой кальцификации. Наравне с нарастанием уровня склеростина подтверждена способность дефицита 1,25(ОН)Д приводить к развитию кальцификации. Заключение. Высокий уровень склеростина в сыворотке крови более 92,5 пмоль/л у больных с ХБП С5Д повышает риск обнаружения признаков сердечно-сосудистой кальцификации (кальцификации стенки аорты и клапанов сердца). Повышение уровня склеростина происходит во взаимосвязи с ростом уровня FGF-23 и снижением 1,25(ОН)Д.

description: Dielectric micro-cavities are widely used as laser resonators and characterizations of their spectra are of interest for various applications. We experimentally investigate micro-lasers of simple shapes (Fabry-Perot, square, pentagon, and disk). Their lasing spectra consist mainly of almost equidistant peaks and the distance between peaks reveals the length of a quantized periodic orbit. To measure this length with a good precision, it is necessary to take into account different sources of refractive index dispersion. Our experimental and numerical results agree with the superscar model describing the formation of long-lived states in polygonal cavities. The limitations of the two-dimensional approximation are briefly discussed in connection with micro-disks.

description: Standard methods in preference learning involve estimating the parameters of discrete choice models from data of selections (choices) made by individuals from a discrete set of alternatives (the choice set). While there are many models for individual preferences, existing learning methods overlook how choice set assignment affects the data. Often, the choice set itself is influenced by an individual's preferences; for instance, a consumer choosing a product from an online retailer is often presented with options from a recommender system that depend on information about the consumer's preferences. Ignoring these assignment mechanisms can mislead choice models into making biased estimates of preferences, a phenomenon that we call choice set confounding; we demonstrate the presence of such confounding in widely-used choice datasets. To address this issue, we adapt methods from causal inference to the discrete choice setting. We use covariates of the chooser for inverse probability weighting and/or regression controls, accurately recovering individual preferences in the presence of choice set confounding under certain assumptions. When such covariates are unavailable or inadequate, we develop methods that take advantage of structured choice set assignment to improve prediction. We demonstrate the effectiveness of our methods on real-world choice data, showing, for example, that accounting for choice set confounding makes choices observed in hotel booking and commute transportation more consistent with rational utility-maximization.

description: We construct the off-shell BV realization of N=1, d=10 SYM with 7 auxillary fields. This becomes possible due to materialized ghost phenomenon. Namely, supersymmetry ghosts are coordinates on a manifold B of 10-dimensional spinors with pure spinors cut out. Auxillary fields are sections of a bundle over B, and supersymmetry transformations are nonlinear in ghosts. By integrating out axillary fields we obtain on-shell supersymmetric BV action with terms quadratic in antifields. Exactly this on-shell BV action was obtained in our previous paper after integration out of auxiliary fields in the framework of Pure Spinor Superfield Formalism.

description: Recently, we proposed a metasurface design for chiral sensing that (i) results in enhanced chiroptical signals by more than two orders of magnitude for ultrathin, subwavelength, chiral samples over a uniform and accessible area, (ii) allows for complete measurements of the total chirality (magnitude and sign of both its real and imaginary part), and (iii) offers the possibility for a crucial signal reversal (excitation with reversed polarization) that enables chirality measurements in an absolute manner, i.e., without the need for sample removal. Our design is based on the anisotropic response of the metasurface, rather than the superchirality of the generated near-fields, as in most contemporary nanophotonic-based chiral sensing approaches. Here, we derive analytically, and verify numerically, simple formulas that provide insight to the sensing mechanism and explain how anisotropic metasurfaces, in general, offer additional degrees of freedom with respect to their isotropic counterparts. We provide a detailed discussion of the key functionalities and benefits of our proposed design and we demonstrate practical measurement schemes for the unambiguous determination of an unknown chirality. Last, we provide the design principles towards broadband operation - from near-infrared to near-ultraviolet frequencies - opening the way for highly sensitive nanoscale chiroptical spectroscopy.

Dynamic Effects Increasing Network Vulnerability to Cascading Failures

description: We study cascading failures in networks using a dynamical flow model based on simple conservation and distribution laws to investigate the impact of transient dynamics caused by the rebalancing of loads after an initial network failure (triggering event). It is found that considering the flow dynamics may imply reduced network robustness compared to previous static overload failure models. This is due to the transient oscillations or overshooting in the loads, when the flow dynamics adjusts to the new (remaining) network structure. We obtain {\em upper} and {\em lower} limits to network robustness, and it is shown that {\it two} time scales $τ$ and $τ_0$, defined by the network dynamics, are important to consider prior to accurately addressing network robustness or vulnerability. The robustness of networks showing cascading failures is generally determined by a complex interplay between the network topology and flow dynamics, where the ratio $χ=τ/τ_0$ determines the relative role of the two of them.

description: We consider the population genetics problem: how long does it take before some member of the population has $m$ specified mutations? The case $m=2$ is relevant to onset of cancer due to the inactivation of both copies of a tumor suppressor gene. Models for larger $m$ are needed for colon cancer and other diseases where a sequence of mutations leads to cells with uncontrolled growth.

description: The dynamics of fragmentation and vibration of molecular systems with a large number of coupled degrees of freedom are key aspects for understanding chemical reactivity and properties. Here we present a resonant inelastic X-ray scattering (RIXS) study to show how it is possible to break down such a complex multidimensional problem into elementary components. Local multimode nuclear wave packets created by X-ray excitation to different core-excited potential energy surfaces (PESs) will act as spatial gates to selectively probe the particular ground-state vibrational modes and, hence, the PES along these modes. We demonstrate this principle by combining ultra-high resolution RIXS measurements for gas-phase water with state-of-the-art simulations.

description: The Ramsey fringes formation during the excitation of topological coherent modes of a Bose-Einstein condensate by an external modulating field is considered. The Ramsey fringes appear when a series of pulses of the excitation field is applied. In both Rabi and Ramsey interrogations, there is a shift of the population maximum transfer due to the strong non-linearity present in the system. It is found that the Ramsey pattern itself retains information about the accumulated relative phase between both ground and excited coherent modes.

description: We present an advanced lateral triple quantum dot made by local anodic oxidation. Three dots are coupled in a starlike geometry with one lead attached to each dot thus allowing for multiple path transport measurements with two dots per path. In addition charge detection is implemented using a quantum point contact. Both in charge measurements as well as in transport we observe clear signatures of states from each dot. Resonances of two dots can be established allowing for serial transport via the corresponding path. Quadruple points with all three dots in resonance are prepared for different electron numbers and analyzed concerning the interplay of the simultaneously measured transport along both paths.

description: The first luminous objects in the concordance cosmology form by molecular hydrogen cooling in dark matter dominated halos of masses ~10^6 M_sun. We use Eulerian adaptive mesh refinement simulations to demonstrate that in the presence of a large soft ultraviolet radiation background, molecular hydrogen is the dominant coolant. Even for very large radiation backgrounds, the halo masses that cool and collapse are up to two orders of magnitude smaller than the halos that cool via atomic hydrogen line cooling. The abundance of cooling halos and the cosmic mass fraction contained within them depends exponentially on this critical mass scale. Consequently, the majority of current models of cosmological reionization, chemical evolution, supermassive black hole formation, and galaxy formation underestimate the number of star forming progenitors of a given system by orders of magnitude. At the highest redshifts, this disagreement is largest. We also show that even in the absence of residual electrons, collisional ionization in central shocks create a sufficient amount of electrons to form molecular hydrogen and cool the gas in halos of virial temperatures far below the atomic cooling limit.

description: We prove that a Banach space X is not super-reflexive if and only if the hyperbolic infinite tree embeds metrically into X. We improve one implication of J.Bourgain's result who gave a metrical characterization of super-reflexivity in Banach spaces in terms of uniforms embeddings of the finite trees. A characterization of the linear type for Banach spaces is given using the embedding of the infinite tree equipped with a suitable metric.

AC Hopping Magnetotransport Across the Spin Flop Transition in Lightly Doped La_2CuO_4

description: The weak ferromagnetism present in insulating La_{2}CuO_4 at low doping leads to a spin flop transition, and to transverse (interplane) hopping of holes in a strong external magnetic field. This results in a dimensional crossover 2D $\to$ 3D for the in-plane transport, which in turn leads to an increase of the hole's localization length and increased conduction. We demonstrate theoretically that as a consequence of this mechanism, a frequency-dependent jump of the in-plane ac hopping conductivity occurs at the spin flop transition. We predict the value and the frequency dependence of the jump. Experimental studies of this effect would provide important confirmation of the emerging understanding of lightly doped insulating La_{2-x}Sr_xCuO_4.

Line and continuum variability of two intermediate-redshift, high-luminosity quasars

description: It has been shown that the luminosity of AGNs and the size of their broad line region obey a simple relation of the type R=a L^g, from faint Seyfert nuclei to bright quasars, allowing single-epoch determination of the central black hole mass M=b L^g D^2 from their luminosity L and width of H_beta emission line. Adopting this mass determination for cosmological studies requires the extrapolation to high z and L of a relation whose calibration relies so far on reverberation mapping measurements performed for L<10^46 erg/s and z<0.4. We initiated a campaign for the monitoring of a few luminous, intermediate z quasars whose apparent magnitude V<15.7 allows observations with a 1.8m telescope, aimed at proving that emission lines vary and respond to continuum variations even for luminosities >10^47 erg/s, and determining eventually their M_BH from reverberation mapping. We have repeatedly performed simultaneous observations of quasars and reference stars to determine relative variability of continuum and emission lines. We describe the observations and methods of analysis. For the quasars PG1634+706 and PG1247+268 we obtain light-curves respectively for CIII], MgII and for CIV, CIII] emission lines with the relevant continua. During 3.2 years of observation, in the former case no continuum variability has been detected and the evidence for line variability is marginal, while in the latter case both continuum and line variability are detected with high significance and the line variations appear correlated with continuum variations. The detection of the emission line variability in a quasar with L~10^47 erg/s encourages the prosecution of the campaign which should provide a black hole mass estimate in other 5-6 years, constraining the M_BH-L relation in a poorly explored range of luminosity.
