description: Die Vulkanite des Laacher-See-Gebietes in der Eifel können mit den Terrassenbildungen des Rheines zeitlich korreliert und ihre Föderfolge auf diese Weise stratigraphisch festgelegt werden. Dadurch bietet sich eine Möglichkeit, die K-Ar-Datierungsmethode an Proben von pleistozänem Alter zu testen und zu prüfen, ob die physikalisch bestimmte Sequenz mit der geologischen übereinstimmt. Datierungen wurden vorgenommen an 13 Sanidinen, 7 Biotiten, 2 Augiten und 14 Gesteinen der Eifel, ferner als Ergänzung an 6 Gesteinen der Umgebung von Agde, Dept. Hérault, Südfrankreich. Die meisten Datierungen ergaben geologisch wahrscheinliche Alter. Sie reichen in der Eifel von 570.10³a bis 100.10³a, bei Agde von 1400.10³a bis 640.10³a. Diffusionsexperimente an Sanidinen und Biotiten zeigten, daß das atmosphärische Argon durch Ausheizen nicht zufriedenstellend entfernt werden kann, ohne daß radiogenes Argon verloren geht. Eine Kontrollprobe des abgeheizten radiogenen Gases mit radioaktivem Ar(39) wurde getestet und erwies sich als nützliche Korrekturgröße.

description: The aim of the research was to show the evolution of added value in the export of Polish and selected European countries with particular emphasis on products bioeconomy. For the analysis the trade statistics of added value published by the WTO and the OECD have been used. The results show that in the analyzed period there was a significant increase in the domestic value-added gross export, higher than the others (except for Russia) countries analyzed. Despite such a significant increase the domestic value added per capita in Polish exports significantly differs from most of the analyzed countries of Central and Eastern Europe. In the case of bioeconomy products their participation in the domestic value-added in Polish gross exports was significantly higher than in other products. In the analyzed period the decline in the share of domestic value added in Polish export of bioeconomy products was also lower in relation to other products.

description: We give formulas for the number of ad-nilpotent ideals of a Borel subalgebra of a Lie algebra of type B or D containing a fixed number of root spaces attached to simple roots. This result solves positively a conjecture of Panyushev (cf. D. Panyushev, ad-nilpotent ideals: generators and duality, J. of Alg., to appear) and affords a complete knowledge of the above statistics for any simple Lie algebra. We also study the restriction of the above statistics to the abelian ideals of a Borel subalgebra, obtaining uniform results for any simple Lie algebra.

----------------------------------
Abstract— To accomplish secure group communication, it is essential to share a unique cryptographic key among group members. The underlying challenges to group key agreement are scalability, efficiency, and security. In a dynamic group environment, the rekeying process is more frequent; therefore, it is more crucial to design an efficient group key agreement protocol. Moreover, with the emergence of various group-based services, it is becoming common for several multicast groups to coexist in the same network. These multicast groups may have several shared users; a join or leave request by a single user can trigger regeneration of multiple group keys. Under the given circumstances the rekeying process becomes a challenging task. In this work, we propose a novel methodology for group key agreement which exploits the state vectors of group members. The state vector is a set of randomly generated nonce instances which determine the logical link between group members and which empowers the group member to generate multiple cryptographic keys independently. Using local knowledge of a secret nonce, each member can generate and share a large number of secure keys, indicating that SGRS inherently provides a considerable amount of secure subgroup multicast communication using subgroup multicasting keys derived from local state vectors. The resulting protocol is secure and efficient in terms of both communication and computation.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Salient object detection is evaluated using binary ground truth with the labels being salient object class and background. In this paper, we corroborate based on three subjective experiments on a novel image dataset that objects in natural images are inherently perceived to have varying levels of importance. Our dataset, named SalMoN (saliency in multi-object natural images), has 588 images containing multiple objects. The subjective experiments performed record spontaneous attention and perception through eye fixation duration, point clicking and rectangle drawing. As object saliency in a multi-object image is inherently multi-level, we propose that salient object detection must be evaluated for the capability to detect all multi-level salient objects apart from the salient object class detection capability. For this purpose, we generate multi-level maps as ground truth corresponding to all the dataset images using the results of the subjective experiments, with the labels being multi-level salient objects and background. We then propose the use of mean absolute error, Kendall's rank correlation and average area under precision-recall curve to evaluate existing salient object detection methods on our multi-level saliency ground truth dataset. Approaches that represent saliency detection on images as local-global hierarchical processing of a graph perform well in our dataset.

description: Die Älteren Schotter sind an den Fußflächen des Schwarzwaldwestrandes unter würmzeitlichen Lößlehmdecken auf den Interfluvien relikthaft verbreitet. Sie setzen sich aus fluvialen Umlagerungsprodukten von periglazialem Hangschutt und Moräne zusammen und sind in der Rißkaltzeit abgelagert worden. Durch würmzeitliche und holozäne Flußsysteme werden sie beständig abgetragen und umgelagert. Im Norsinger Ahbach hat sich im jüngeren Holozän eine Rinne in die Hochterrasse lokal eingetieft, wobei ein mehrfacher Wechsel von Tiefenerosion und Akkumulation stattgefunden hat. In der Vorbergzone können die Älteren Schotter dort, wo sie das Liegende von mehrgliedrigen Löß-Boden-Sequenzen bilden, mit Sicherheit ins Präriß gestellt werden. Eine genaue zeitliche Datierung in diesem Raum kann jedoch solange nicht gegeben werden, bis eine befriedigende Chronostratigraphie Breisgauer Lösse vorliegt.

description: The main objective of the paper was to check if and which monopolistic markups of 29 Polish food sector branches can be regarded as potential predictors of business cycle changes. Markups were measured based on a non-overhead labour input margin, whereas the business cycle was considered on the three levels of branch, sector and the whole economy, with following indicators: value of production for the first two, and GDP for the macro cycle. Research methods were panel regressions and cross-correlations. In the analysed period 2000-2013 markups were countercyclical regarding macro cycle and procyclical regarding sectorial and branch cycles. Changes in market structures of 10 Polish food sector branches could be used as predictors for the macro business cycle, and of 6 – for the sectorial business cycle.
Factors influencing foster placement outcomes for children in British Columbia
Creators: name: Strubin, Tanya
Publisher: name: University of British Columbia
Year: 2011

description: An investigation of factors thought to contribute to the breakdown of foster homes for children in British Columbia was completed in this study. Data was collected from 22 foster parents across the province; all members of the British Columbia Federation of Foster Parents. Through the use of survey questionnaires, foster parents were asked to respond to questions regarding their experiences with a foster child aged 6 to 12 years formerly in their care. Data was collected to indicate the presence of difficult child behaviour, supportive services available to foster parents and parental attributions towards care giving outcomes. Family systems theory and social cognition theory provided a theoretical background to this research through the discussion of family dynamics and parental attributions. Variables under study in this project have been found in previous research to affect foster placement stability. Results revealed that verbally aggressive behaviour by children may affect placement stability while physical aggression and delinquent behaviour do not. Results also indicated that foster parent attributions regarding children in their care may relate to foster placement outcomes. Support from the foster care system appeared to have limited impact on the success of placement. However, foster parents reported an overall lack of available support. Throughout this study, the need for further research into foster placement outcomes is highlighted.

Abstract-—The current internet architecture is inefficient in fulfilling the demands of newly emerging internet applications. To address this issue, several over-the-top (OTT) application-level solutions have been employed, making the overall architecture very complex. Information-centric-networking (ICN) architecture has emerged as a promising alternative solution. The ICN architecture decouples the content from the host at the network level and supports the temporary storage of content in an innetwork cache. Fundamentally, the ICN can be considered a multisource, multicast content-delivery solution. Because of the benefits of network coding in multicasting scenarios and proven benefits in distributed storage networks, the network coding is apt for the ICN architecture. In this study, we propose a solvable linear network-coding scheme for the ICN architecture. We also propose a practical implementation of the network-coding scheme for the ICN, particularly for the content-centric network (CCN) architecture, which is termed the coded CCN (CCCN). The performance results show that the network-coding scheme improves the performance of the CCN and significantly reduces the network traffic and average download delay.
Study of Small-Scale Anisotropy of Ultrahigh Energy Cosmic Rays Observed in Stereo by HiRes

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The High Resolution Fly's Eye (HiRes) experiment is an air fluorescence detector which, operating in stereo mode, has a typical angular resolution of 0.6 degrees and is sensitive to cosmic rays with energies above 10^18 eV. HiRes is thus an excellent instrument for the study of the arrival directions of ultrahigh energy cosmic rays. We present the results of a search for anisotropies in the distribution of arrival directions on small scales (<5 degrees) and at the highest energies (>10^19 eV). The search is based on data recorded between 1999 December and 2004 January, with a total of 271 events above 10^19 eV. No small-scale anisotropy is found, and the strongest clustering found in the HiRes stereo data is consistent at the 52% level with the null hypothesis of isotropically distributed arrival directions.

The field surrounding NGC 7603: cosmological or non-cosmological redshifts?

description: We present new observations of the field surrounding the Seyfert galaxy NGC 7603, where four galaxies with different redshifts--NGC 7603 (z=0.029), NGC 7603B (z=0.057) and two fainter emission line galaxies (z=0.245 and z=0.394)--are apparently connected by a narrow filament, leading to a possible case of anomalous redshift. The observations comprise broad and narrow band imaging and intermediate resolution spectroscopy of some of the objects in the field. The new data confirm the redshift of the two emission-line objects found within the filament connecting NGC 7603 and NGC 7603B, and settles their type with better accuracy. Although both objects are point-like in ground based images, using HST archive images we show that the objects have structure with a FWHM=0.3-0.4 arcsec. This and the relative strength and width of the main spectral lines allow us to classify these as HII galaxies with very vigorous star formation, while the rest of the filament and NGC 7603B lack star formation. We delineate the halo of NGC 7603 out to 26.2 mag/square arcsec in the Sloan r band filter and find evidence for strong internal distortions. New narrow emission line galaxies at z=0.246, 0.117 and 0.401 are also found at respectively 0.8, 1.5 and 1.7 arcmin to the West of the filament within the fainter contour of this halo. The probability of three background galaxies of any type with apparent B-magnitudes up to 16.6, 21.1 and 22.1 (the observed magnitudes, extinction correction included) being randomly projected on the filament of the fourth galaxy (NGC 7603) is computed resulting ~ 3 x 10^(-9).

description: Neuere Kartier- und Bohrergebnisse machen eine teilweise Revision der bisherigen Ansichten über die Ausbreitung des Eem-Meeres notwendig. Nach Dechend (1958) und Sindowski (1958, 1965) erreichte das Eem-Meer während seines Höchststandes ungefähr die heutige Küstenlinie. Im Bereich der ostfriesischen Küste haben die Arbeiten von Barckhausen (1984) und Barckhausen & Streif (1978) einige kleinere Veränderungen des eemzeitlichen Küstenverlaufs ergeben. Im Elbe-Weser-Dreieck muß die Küstenlinie des Eem-Meeres um bis zu 22 km in die Hadelner Bucht verlegt werden. Sie entspricht dadurch der maximalen Ausbreitung des holozänen Meeres vom Subboreal bis Subatlantikum.

description: Whereas ornithischian dinosaurs are well known from Jurassic and Cretaceous deposits, deciphering the origin and early evolution of the group remains one of the hardest challenges for palaeontologists. So far, there are no unequivocal records of ornithischians from Triassic beds. Here, we present an alternative evolutionary hypothesis that suggests consideration of traditional ‘silesaurids' as a group of low-diversity clades representing a stem group leading to core ornithischians (i.e. unambiguous ornithischians, such as Heterodontosaurus tucki). This is particularly interesting because it fills most of the ghost lineages that emerge from the Triassic. Following the present hypothesis, the lineage that encompasses the Jurassic ornithischians evolved from ‘silesaurids' during the Middle to early Late Triassic, while typical ‘silesaurids' shared the land ecosystems with their relatives until the Late Triassic, when the group completely vanished. Therefore, Ornithischia changes from an obscure to a well-documented clade in the Triassic and is represented by records from Gondwana and Laurasia. Furthermore, according to the present hypothesis, Ornithischia was the first group of dinosaurs to adopt an omnivorous/herbivorous diet. However, this behaviour was achieved as a secondary step instead of an ancestral condition for ornithischians, as the earliest member of the clade is a faunivorous taxon. This pattern was subsequently followed by sauropodomorph dinosaurs. Indeed, the present scenario favours the independent acquisition of an herbivorous diet for ornithischians and sauropodomorphs during the Triassic, whereas the previous hypotheses suggested the independent acquisition for sauropodomorphs, ornithischians, and ‘silesaurids'.

description: The main objective of this study is to carry out a complex economic analysis of organic manure application. Researches were carried for years 2010-2015. Organic manure, a by-product of animal husbandry, is one of the oldest and most valuable materials in agriculture. The primary purpose of using organic manure is to improve soil fertility. Since the 90s, Hungary has been facing changes in the ownership of agricultural ventures, the number of big farms decreased and the amount of livestock was reduced in the main sectors of animal husbandry. Hungary, as a member of the European Union, has to conform to the current environmental protection regulations which also refer to the disposal of organic manure that can only be performed if significant investments are made. It can be concluded that the economic efficiency of organic manure application is primarily determined by transport distance and the specific transport method. In addition, the establishment of manure containers can be considered to be unproductive investments which affect the economic efficiency of using organic manure negatively.

description: We show that in a one-dimensional translationally invariant tight binding chain, non-dispersing wave packets can in general be realized as Floquet eigenstates -- or linear combinations thereof -- using a spatially inhomogeneous drive, which can be as simple as modulation on a single site. The recurrence time of these wave packets (their "round trip" time) locks in at rational ratios $sT/r$ of the driving period $T$, where $s,r$ are co-prime integers. Wave packets of different $s/r$ can co-exist under the same drive, yet travel at different speeds. They retain their spatial compactness either infinitely ($s/r=1$) or over long time ($s/r \neq 1$). Discrete time translation symmetry is manifestly broken for $s \neq 1$, reminiscent of Floquet time crystals. We further demonstrate how to reverse-engineer a drive protocol to reproduce a target Floquet micromotion, such as the free propagation of a wave packet, as if coming from a strictly linear energy spectrum. The variety of control schemes open up a new avenue for Floquet engineering in quantum information sciences.

description: Aus der periglazialen Füllung des von einem alten Rheinlauf angelegten Mäanders von Niederaußem (nordwestlich Köln) stammt eine kleine Aufsammlung von Wühlmaus-Resten, und zwar einer Halsbandlemming-Form. Diese unterscheidet sich von den beiden in Europa vorkommenden jungquartären Arten Dicrostonyx henseli Hinton und D. Gulielmi Sanford deutlich durch einfacheren Bau des Kauflächenbildes der Molaren. Auf eine besondere Benennung der offensichtlich neuen Art wurde vorläufig verzichtet. Zwecks Klärung der Frage nach dem zeitlichen Auftreten der Gattung Dicrostonyx im Quartär Europas wurde die einschlägige Literatur kritisch überprüft. Mit Sicherheit darf heute gesagt werden, daß Dicrostonyx bereits zum Bestand vor-würmzeitlicher glazialer Faunen gehört. Die Funde aus dem Quartärprofil von Niederaußem, das Ablagerungen der Riß- oder (wahrscheinlicher) sogar einer noch älteren Eiszeit repräsentiert, sind in diesem Zusammenhang von großer Bedeutung.

Bilal, M.; Kang, S.-G. An Authentication Protocol for Future Sensor Networks. Sensors 2017, 17, 979.

Abstract-Authentication is one of the essential security services in Wireless Sensor Networks (WSNs) for ensuring secure data sessions. Sensor node authentication ensures the confidentiality and validity of data collected by the sensor node, whereas user authentication guarantees that only legitimate users can access the sensor data. In a mobile WSN, sensor and user nodes move across the network and exchange data with multiple nodes, thus experiencing the authentication process multiple times. The integration of WSNs with Internet of Things (IoT) brings forth a new kind of WSN architecture along with stricter security requirements; for instance, a sensor node or a user node may need to establish multiple concurrent secure data sessions. With concurrent data sessions, the frequency of the re-authentication process increases in proportion to the number of concurrent connections. Moreover, to establish multiple data sessions, it is essential that a protocol participant have the capability of running multiple instances of the protocol run, which makes the security issue even more challenging. The currently available authentication protocols were designed for the autonomous WSN and do not account for the above requirements. Hence, ensuring a lightweight and efficient authentication protocol has become more crucial. In this paper, we present a novel, lightweight and efficient key exchange and authentication protocol suite called the Secure Mobile Sensor Network (SMSN) Authentication Protocol. In the SMSN a mobile node goes through an initial authentication procedure and receives a re-authentication ticket from the base station. Later a mobile node can use this re-authentication ticket when establishing multiple data exchange sessions and/or when moving across the network. This scheme reduces the communication and computational complexity of the authentication process. We proved the strength of our protocol with rigorous security analysis (including formal analysis using the BAN-logic) and simulated the SMSN and previously proposed schemes in an automated protocol verifier tool. Finally, we compared the computational complexity and communication cost against well-known authentication protocols.
The effect of nutrients on the rate of protein degradation in isolated small intestinal enterocytes from Sprague-Dawley rats

description: Nutrients affect small intestinal protein mass and metabolism. Studies on the effect of nutrients on small intestinal protein degradation are limited due to a lack of a proper method. The objectives of this study were to establish a method to directly estimate protein degradation in isolated enterocytes from rats, and to test the effect of energy substrates and amino acids on protein degradation. Male Sprague-Dawley rats (150-200 g, n ≥8 per treatment) were used. Cell viability, tyrosine release as an indicator of protein degradation, and the effect of osmolarity were measured to establish the method. The effects of energy substrates (50 mM glucose, 20 mM (β-hydroxybutyrate, 4.7 mM butyrate, and 30 mM glutamine) and amino acid solutions (30 mM amino acids mix, 30 mM glutamate, 1% ammonium, and 30 mM amino acids mix plus 50 mM glucose) on protein degradation were measured. Average viability at time 30 min was 85.8% (range 81-94%). Tyrosine release was linear over the course of experiments, indicating constant protein degradation (R²= 0.9943) (p<0.05). Osmolarity, glucose, and glutamine had no effect on protein degradation. [β-hydroxybutyrate significantly decreased it (-16%; p<0.05), whereas butyrate slightly increased it (+ 5%; p<0.05). The mixture of amino acids and glutamate increased (p<0.05) protein degradation (+ 10%) compared to control. Ammonium had no effect. The mixture of amino acids plus glucose decreased (-13%; p<0.05) protein degradation compared to the mix of amino acids only. High viability and constant rate of protein degradation indicate successful establishment of a method to estimate protein degradation in isolated small intestinal enterocytes from rats. The mixture of amino acids or glutamate may have acted as an energy source for the highly energy dependent enterocyte. Addition of glucose to the mixture of amino acids may have decreased the concentration of amino acids in tissue and abolished their effect. The large effect of β-hydroxybutyrate suggests a potential positive role for ketone bodies to limit the loss of small intestinal protein mass by decreasing protein degradation. These findings might be particularly important in catabolic conditions such as starvation or total parenteral nutrition, where the loss of small intestinal protein mass is substantial.

description: We report new spectroscopic observations of the recently discovered transiting planet OGLE-TR-56b with the Keck/HIRES instrument. Our radial velocity measurements with errors of ~100 m/s show clear variations that are in excellent agreement with the phasing (period and epoch) derived from the OGLE transit photometry, confirming the planetary nature of the companion. The new data combined with measurements from the previous season allow an improved determination of the mass of the planet, M_p = 1.45 +/- 0.23 M_Jup. All available OGLE photometry, including new measurements made this season, have also been analyzed to derive an improved value for the planetary radius of R_p = 1.23 +/- 0.16 R_Jup. We discuss the implications of these results for the theory of extrasolar planets.

description: The eV-scale sterile neutrino has been proposed to explain some anomalous results in experiments, \textit{such as} the deficit of reactor neutrino fluxes and the excess of $\barν_μ\to\barν_e$ in LSND. This hypothesis can be tested by future core-collapse supernova neutrino detection independently since the active-sterile mixing scheme affects the flavor conversion of neutrinos inside the supernova. In this work, we compute the predicted supernova neutrino events in future detectors -- DUNE, Hyper-K, and JUNO -- for neutrinos emitted during the neutronization burst phase when the luminosity of $ν_e$ dominates the other flavors. We find that for a supernova occurring within 10 kpc, the difference in the event numbers with and without sterile neutrinos allows to exclude the sterile neutrino hypothesis at more than $99\%$ confidence level robustly. The derived constraints on sterile neutrinos mixing parameters are comparably better than the results from cosmology and on-going or proposed reactor experiments by more than two orders of magnitude in the $\sin^22θ_{14}$-$Δm_{41}^2$ plane.

description: Ein Bohrkern aus der südlichen Nordsee (54° 44,5' N, 4° 30' E) wurde auf Pollen, botanische Makroreste, Mollusken sowie Minerale und Schwermetalle untersucht. Im Liegenden befindet sich ein echter Basistorf, auf den ohne Erosion Süßwasser-, Brackwasser- und Salzwassersedimente folgen. Der Transgressionskontakt liegt bei 42,5 m unter Mittelwasser und wurde auf spätes Boreal (etwa 8150 Jahre BP.) datiert, die Profilstelle blieb bis ins Atlantikum im ufernahen Flachwasserbereich. Es folgen nach einem langen zeitlichen Hiatus junge Tiefwassersedimente, die seit oder nach dem Mittelalter abgelagert worden sind. Im obersten Meter steigt der Schwermetallgehalt stark an, was mit der anthropogenen Verschmutzung seit 1880 AD begründet wird.

Das Alter der Gletscherschrammen von Velpke

description: Über Rhätsandstein mit zwei Systemen von Gletscherschrammen wurden die glazigenen Deckschichten untersucht und eine Serie von stellenweise übereinanderliegenden Grundmoränen nachgewiesen, deren nicht überall erhaltene älteste das ältere Schrammensystem schuf. Der geschiebekundliche Nachweis einer allmählichen Änderung in der Richtung der als elstereiszeitlich erkannten Gletscherbewegung läßt es möglich erscheinen, daß die jüngere Schrammenrichtung durch einen jüngeren elstereiszeitlichen Eisvorstoß verursacht wurde. Im Zusammenhang mit gletscherbedingten Gesteinsausbrüchen, wie sie als Kleinform an Parabelrissen beschrieben wurden, wird jedoch auch eine andere Entstehungsmöglichkeit angedeutet. Die angewandten Untersuchungsmethoden lassen es möglich erscheinen, auch in anderen Grundmoränenaufschlüssen differenzierte Bewegungsabläufe von Eisbewegungen und somit Untergliederungen einer Eiszeit herauszulesen.

description: Self-supervised learning has attracted plenty of recent research interest. However, most works for self-supervision in speech are typically unimodal and there has been limited work that studies the interaction between audio and visual modalities for cross-modal self-supervision. This work (1) investigates visual self-supervision via face reconstruction to guide the learning of audio representations; (2) proposes an audio-only self-supervision approach for speech representation learning; (3) shows that a multi-task combination of the proposed visual and audio self-supervision is beneficial for learning richer features that are more robust in noisy conditions; (4) shows that self-supervised pretraining can outperform fully supervised training and is especially useful to prevent overfitting on smaller sized datasets. We evaluate our learned audio representations for discrete emotion recognition, continuous affect recognition and automatic speech recognition. We outperform existing self-supervised methods for all tested downstream tasks. Our results demonstrate the potential of visual self-supervision for audio feature learning and suggest that joint visual and audio self-supervision leads to more informative audio representations for speech and emotion recognition.

description: Macroscopic field quantization is presented for a nondispersive photonic dielectric environment, both in the absence and presence of guest atoms. Starting with a minimal-coupling Lagrangian, a careful look at functional derivatives shows how to obtain Maxwell's equations before and after choosing a suitable gauge. A Hamiltonian is derived with a multipolar interaction between the guest atoms and the electromagnetic field. Canonical variables and fields are determined and in particular the field canonically conjugate to the vector potential is identified by functional differentiation as minus the full displacement field. An important result is that inside the dielectric a dipole couples to a field that is neither the (transverse) electric nor the macroscopic displacement field. The dielectric function is different from the bulk dielectric function at the position of the dipole, so that local-field effects must be taken into account.

description: In the past several years, observational entropy has been developed as both a (time-dependent) quantum generalization of Boltzmann entropy, and as a rather general framework to encompass classical and quantum equilibrium and non-equilibrium coarse-grained entropy. In this paper we review the construction, interpretation, most important properties, and some applications of this framework. The treatment is self-contained and relatively pedagogical, aimed at a broad class of researchers.
