description: Current climate models still suffer from many biases which are partly due to excessive subgrid-scale dissipation. Here we systematically develop energetically consistent stochastic energy backscatter (SEB) and deterministic energy backscatter (DEB) parametrization schemes. We implement our schemes in a simplified spectral atmospheric General Circulation Model (GCM). It is shown that the SEB scheme performs better than the DEB scheme at low horizontal resolutions (T21 and T31), whereas the performance of both schemes becomes comparable as the resolution increases to T42 when comparing with our reference simulation at T127 resolution. The energy backscatter parametrization schemes improve eddy variability in low-resolution models and correctly capture the dominant mode of zonal-mean zonal wind variability. The autocorrelation time-scale of low-resolution models is also found to be more consistent with the reference simulation when applying the SEB and DEB parametrizations. Our schemes are scale-adaptive and computationally efficient.

description: Eine zunehmende depressive Symptomatik in Verbindung mit globalen politischen Krisensituationen gibt aktuellen Anlass zu fragen: Wie treffen Menschen Entscheidungen unter Unsicherheit? Ein Ansatz aus der Perspektive des „Predictive Processing“ betrachtet Depression unter der Annahme, dass das menschliche Gehirn ein aktives Organ ist, das sensorische Inputs kontinuierlich mit bereits bestehenden Erwartungen und Kognitionen abgleicht, um optimale Entscheidungen zu treffen. Frühere Forschung deutet darauf hin, dass diese Verarbeitungsstrategie bei Menschen mit depressiven Tendenzen durch zwei Faktoren beeinflusst wird: Einerseits, eine verstärkte Gewichtung negativer Vorinformationen und anderseits ein schnelleres Integrieren von negativen Feedback in deren Entscheidungen. In der vorliegenden Studie trafen die Teilnehmenden Entscheidungen in einem pokerähnlichen Spiel für Protagonist*innen auf Basis dieser Informationsquellen: Bereitgestellt Hintergrundinformationen über die Charaktereigenschaften der Spieler*innen, sowie unmittelbares Feedback nach jeder gesetzten Entscheidung. Die Hypothese einer verzerrten Entscheidungsstrategie aufgrund einer verstärkten Beeinflussung durch negative „priors“ oder durch aufgrund eines höheren Updatens in Richtung negativer „prediction error“ konnte in dieser Studie jedoch nicht bestätigt werden.
description: Increasing prevalence of depressive states in populations, coupled with recent political turbulences around the world should alarm us to investigate how human beings make decisions under conditions of uncertainty. Investigating the topic of depression from a predictive processing perspective is nested on the premise of the brain as a hierarchical, active organ that constantly aligns prior knowledge with current sensory information to make optimal decisions. The problem with depression appears to be two-fold: a high precision to negative priors couple with an impaired belief-updating towards positive information. In this study participants had to make social decision in a poker-like game, where prior and sensory uncertainty was manipulated. However, the claimed assumption of a biased underlying predictive processing inherent to depressive symptoms could not been replicated.

Revisiting the radio interferometer measurement equation. I. A full-sky Jones formalism

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: Since its formulation by Hamaker et al., the radio interferometer measurement equation (RIME) has provided a rigorous mathematical basis for the development of novel calibration methods and techniques, including various approaches to the problem of direction-dependent effects (DDEs). This series of papers aims to place recent developments in the treatment of DDEs into one RIME-based mathematical framework, and to demonstrate the ease with which the various effects can be described and understood. It also aims to show the benefits of a RIME-based approach to calibration. Paper I re-derives the RIME from first principles, extends the formalism to the full-sky case, and incorporates DDEs. Paper II then uses the formalism to describe self-calibration, both with a full RIME, and with the approximate equations of older software packages, and shows how this is affected by DDEs. It also gives an overview of real-life DDEs and proposed methods of dealing with them. Applying this to WSRT data (Paper III) results in a noise-limited image of the field around 3C 147 with a very high dynamic range (1.6 million), and none of the off-axis artifacts that plague regular selfcal. The resulting differential gain solutions contain significant information on DDEs, and can be used for iterative improvements of sky models. Perhaps most importantly, sources as faint as 2 mJy have been shown to yield meaningful differential gain solutions, and thus can be used as potential calibration beacons in other DDE-related schemes.

description: We consider the problem of designing truthful auctions, when the bidders' valuations have a public and a private component. In particular, we consider combinatorial auctions where the valuation of an agent $i$ for a set $S$ of items can be expressed as $v_if(S)$, where $v_i$ is a private single parameter of the agent, and the function $f$ is publicly known. Our motivation behind studying this problem is two-fold: (a) Such valuation functions arise naturally in the case of ad-slots in broadcast media such as Television and Radio. For an ad shown in a set $S$ of ad-slots, $f(S)$ is, say, the number of {\em unique} viewers reached by the ad, and $v_i$ is the valuation per-unique-viewer. (b) From a theoretical point of view, this factorization of the valuation function simplifies the bidding language, and renders the combinatorial auction more amenable to better approximation factors. We present a general technique, based on maximal-in-range mechanisms, that converts any $α$-approximation non-truthful algorithm ($α\leq 1$) for this problem into $Ω(\fracα{\log{n}})$ and $Ω(α)$-approximate truthful mechanisms which run in polynomial time and quasi-polynomial time, respectively.

Estimating Shortwave Clear-Sky Fluxes From Hourly Global Radiation Records by Quantile Regression

description: Estimates of radiative fluxes under cloud-free conditions (“clear-sky”) are required in many fields, from climatic analyses of solar transmission to estimates of solar energy potential for electricity generation. Ideally, these fluxes can be obtained directly from measurements of solar fluxes at the surface. However, common standard methods to identify clear-sky conditions require observations of both the total and the diffuse radiative fluxes at very high temporal resolution of minutes, which restricts these methods to a few, well-equipped sites. Here we propose a simple method to estimate clear-sky fluxes only from typically available global radiation measurements (Rsd) at (half-)hourly resolution. Plotting a monthly sample of observed Rsd against the corresponding incoming solar radiation at the top of atmosphere (potential solar radiation) reveals a typical triangle shape with clear-sky conditions forming a distinct, linear slope in the upper range of observations. This upper slope can be understood as the fractional transmission of solar radiation representative for cloud-free conditions of the sample period. We estimate this upper slope through quantile regression. We employ data of 42 stations of the worldwide Baseline Surface Radiation Network to compare our monthly estimates with the standard clear-sky identification method developed by Long and Ackerman (2000, https://doi.org/10.1029/2000JD900077). We find very good agreement of the derived fractional solar transmission (R2 = 0.73) across sites. These results thus provide confidence in applying the proposed method to the larger set of global radiation measurements to obtain further observational constraints on clear-sky fluxes and cloud radiative effects.

description: La pornografia, fenomeno ampiamente diffuso, basa il suo comprovato successo tra la popolazione e il conseguente ricavo economico non indifferente sull’ostensione pubblica di atti sessuali. I programmi televisivi di intrattenimento, fenomeno di altrettanto ampio successo, mostrano concorrenti alle prese con eventi di vita quotidiana, atti naturali che durante le riprese accadono realmente sulla loro pelle. Quali sono i punti di contatto tra queste tematiche così differenti? La risposta risiede nelle strategie pornografiche di comunicazione. Queste creano i dettami per comunicazioni prettamente visive che attingono dalla pornografia la caratteristica dell’ostensione di atti naturali di qualsiasi tipo (gesti, atti, eventi) ‒ nel caso della pornografia atti sessuali ‒ utilizzati per scopi differenti dal loro significato intrinseco: l’intrattenimento. Le immagini oggetto di queste comunicazioni hanno come nucleo comune emozioni e realtà, elementi garanti di ottimo successo in termini di audience e impatto diretto. L’obiettivo fondamentale e tutto fuorché semplice che le strategie pornografiche affidano alla comunicazione è la stimolazione dell’attenzione del pubblico talvolta morbosa, viva e pulsante sommersa quotidianamente da torrenti di informazioni.

We use the mapping onto a directed polymer (DP) with one end fixed, one free, and the Bethe Ansatz for the replicated attractive boson model. We obtain the generating function of the moments of the DP partition sum as a Fredholm Pfaffian. Our formula, valid for all times, exhibits convergence of the free energy (i.e. KPZ height) distribution to the GOE Tracy Widom distribution at large time.

description: Bose-Einstein correlations of identical pions produced in high-energy pp collisions at the LHC allow a probe of the Pomeron exchange mechanism. The size of the domain which emits the pions depends on the multiplicity of events, but not on the collider energy. This confirms the universal structure of Pomeron exchange. The data at relatively low multiplicities indicate that the size of the source created by one-Pomeron exchange is much less than the size of the proton.

The Obvious in a Nutshell: Science, Medicine, Knowledge, and History

description: Abstract The scope and mission of the history of science have been constant objects of reflection and debate within the profession. Recently, Lorraine Daston has called for a shift of focus: from the history of science to the history of knowledge. Such a move is an attempt at broadening the field and ridding it of the contradictions deriving from its modernist myth of origin and principle of demarcation. Taking the move from a pluralistic concept of medicine, the present paper explores the actual and possible contributions that a history of knowledge can offer to the history of medicine in particular. As we will argue, the history of medicine has always been a history of knowledge, but for good reasons has always stuck to the concept of medicine as its object and problem throughout the ages, including the modern, scientific one. We argue that, in the history of medicine, the demarcation between scientific and non-scientific represents an accident, but is not foundational as in the case of natural science. Furthermore, the history of medicine programmatically played a role in at least two academic domains (history proper and medical education), adjusting historical narratives of medical knowledge to its audience. Accordingly, we underscore that the history of both science and medicine, as traditionally defined, already provides room for almost the whole spectrum of approaches to history. Moreover, their different myths of origin can, and indeed must, be included in the reflexivity of the historical gaze. We argue that the position towards a history of science, medicine, or knowledge is not a question of narrative or theory, rather, it is a question of relevance and awareness of extant contexts.
L’ironia su misura di gatto L’illustrazione per divertire e insegnare

description: Il gatto è da sempre un animale che spesso troviamo nelle nostre case come compagno di vita, con lo scopo di tenerci compagnia. Ma ci siamo mai chiesti cosa pensa lui di noi? Venerati dagli egizi e fin dall’antichità apprezzati soprattutto da greci e romani, i felini condividono con noi gran parte delle nostre giornate e noi in cambio forniamo loro amore, cibo e accoglienza. Come tesi di laurea desideravo realizzare un manuale illustrato per preparare il lettore a fronteggiare l’arrivo di un miagolante amico, il tutto con ironia, raccontato dal punto di vista del gatto che, con un linguaggio giovanile, cerca di istruire il proprio padrone per una buona convivenza. Parlando di animali domestici, l’indole del gatto si distingue molto da quella del cane. Si tratta di animali indipendenti che richiedono meno attenzioni e per la maggior parte delle volte sono loro a decidere quando concedere attenzioni al proprio padrone. Noi possiamo considerarci i padroni di un cane ma il gatto probabilmente considererà se stesso come il nostro padrone. Sul web o nei libri ritroviamo spesso questa differenza di carattere tra gatto e cane, in cui il micio viene ironicamente rappresentato come essere superiore rispetto all’essere umano. Il mio libro rappresenta in maniera ironica lo stereotipo del gatto, con un viaggio attraverso luoghi comuni, esplorandone i comportamenti e allo stesso tempo ponendo attenzione ad un corretto approccio con questo animale per migliorarne il rapporto con l’essere umano.

description: We demonstrate temporal group delays in coherently-coupled high-Q multi-cavity photonic crystals, in an all-optical analogue to electromagnetically induced transparency. We report deterministic control of the group delay up to 4x the single cavity lifetime in our CMOS-fabricated room-temperature chip. Supported by three-dimensional numerical simulations and theoretical analyses, our multi-pump beam approach enables control of the multi-cavity resonances and inter-cavity phase, in both single and double transparency peaks. The standing-wave wavelength-scale photon localization allows direct scalability for chip-scale optical pulse trapping and coupled-cavity QED.

Development of a Data Fusion-Based Multi-Sensor System for Hybrid Sheet Molding Compound
Creators: name: Schäferling, Marielouise
Publisher: name: Karlsruhe
Year: 2019

description: In den letzten Jahren ist die Produktion von faserverstärkten Kunststoffen stetig gestiegen. Ein Teil davon ist das glasfaser-verstärkte Sheet Molding Compound (SMC), welches sich durch seine günstigen Herstellkosten und einfache Verarbeitung auszeichnet. Allerdings weist dieses Material schlechte mechanische Eigenschaften auf, welche eine Anwendung für Strukturbauteile verhindert. Um diesem Nachteil entgegen zu wirken, wird das diskontinuierliche Glasfaser-SMC lokal mit kontinuierlichem Carbonfaser-SMC verstärkt. Dadurch können die Vorteile des günstigen und leicht zu verarbeitenden Glasfaser-SMC mit den sehr guten mechanischen Eigenschaften von Carbonfaser-SMC in Faserrichtung kombiniert werden.
Die Kombination dieser beiden Werkstoffe kann bereits in einem frühen Produktionsschritt zu einer Vielzahl an möglichen Defekten wie beispielsweise Delamination, Falten oder Winkelabweichungen führen. Um keine weiteren wertschöpfenden Maßnahmen an defekten Bauteilen durchzuführen, muss die Qualitätssicherung bereits in einem frühen Prozessstadium durchgeführt werden.
Die zu entdeckenden Fehler werden in außen- und innenliegende Defekte unterteilt. Da kein System verfügbar ist, um alle relevanten Defekte zu detektieren, wird pro Defektklasse ein Messsystem benötigt. Zudem erstreckt sich der Anwendungsbereich neben dem Halbzeug auch auf das ausgehärtete Bauteil. Das Laserlichtschnittsystem und die aktive Thermografie, in Form der Puls-Phasen-Thermografie, haben sich als geeignet erwiesen.
Beide Systeme werden zunächst einzeln untersucht und für den vorliegenden Anwendungsfall angepasst. Dabei ist es möglich die Puls-Phasen-Thermografie methodisch zu einer Tiefenauswertung weiterzuentwickeln. Des Weiteren werden Fehler nicht nur detektiert, sondern auch definiert.
Anschließen werden die beiden Systeme in einem Multisensorik-System zusammengeführt. Mit Hilfe der Datenfusion sind eine Auswertung von außen- und innenliegenden Defekten, sowie die Ermittlung von geometrischen Zusammenhängen zwischen einzelnen Defekten möglich. Durch den Aufbau eines Schichtmodells wird zusätzlich eine benutzerfreundliche Auswertung ermöglicht, welche dem Anwender schnell einzelne Schichten aufzeigen kann. Mit der Ermittlung der Messunsicherheit des Multisensorik-Systems wird die Güte aufgezeigt.

A Spectrally Consistent Globally Defined Geodetic Mean Dynamic Ocean Topography
Creators: name: Siegismund, Frank
Publisher: name: FID GEO
Year: 2020

description: The space-borne geodetic temporal mean dynamic topography (MDT) is obtained from the difference of altimetric mean sea surface (MSS) h and the geoid height N. With the geostrophic surface currents obtained from its gradient, the MDT is an essential parameter when describing the ocean dynamics. Spectral consistency of h and N is crucial to minimize MDT errors. Frequently, h is globalized to allow for a spherical harmonic analysis, and small scales beyond maximum degree and order (d/o) resolved in the geoid are cut off. However, common globalization causes ocean-land steps in h−N and spectral inconsistencies of N and h over land. To overcome both issues, a methodology is proposed based on globalization of the MDT. A Laplacian smoother with the coastal MDT values as boundary condition is applied, resulting in a smooth surface over land and a continuous ocean-land transition. The new methodology strongly reduces Gibbs effects and the need to work with high-resolution MDTs to minimize them. Reduction of resolution is tested to reduce MDT uncertainties caused by the commission error expected to increase with decreasing scale. Applying drifter data and a high-resolution hydrodynamic ocean model, it is shown that for the Gulf Stream and the Kuroshio, geodetic MDTs applying recent combined geoid models contain physical information up to at least d/o 420 (48-km spatial scale). For oceanic regions with strong geoid gradients, a higher-resolution MDT might be needed to prevent Gibbs effects caused by remaining inconsistencies between the geoid and the MSS.
The modulated low-temperature structure of malayaite, CaSnOSiO4

description: The crystal structure of the mineral malayaite has been studied by single-crystal X-ray diffraction at a temperature of 20 K and by calculation of its phonon dispersion using density functional perturbation theory. The X-ray diffraction data show first-order satellite diffraction maxima at positions q = 0.2606 (8)b*, that are absent at room temperature. The computed phonon dispersion indicates unstable modes associated with dynamic displacements of the Ca atoms. The largest-frequency modulus of these phonon instabilities is located close to a wavevector of q = 0.3b*. These results indicate that the malayaite crystal structure is incommensurately modulated by static displacement of the Ca atoms at low temperatures, caused by the softening of an optic phonon with Bg symmetry.
Large-angle OBServaTory with Energy Resolution for Synoptic X-ray Studies (LOBSTER-SXS)

description: The soft X-ray band hosts a larger, more diverse range of variable sources than any other region of the electromagnetic spectrum. They are stars, compact binaries, SMBH's, the X-ray components of Gamma-Ray Bursts, their X-ray afterglows, and soft X-ray flares from supernova. We describe a concept for a very wide field (~ 4 ster) modular hybrid X-ray telescope system that can measure positions of bursts and fast transients with as good as arc second accuracy, the precision required to identify fainter and increasingly more distant events. The dimensions and materials of all telescope modules are identical. All but two are part of a cylindrical lobster-eye telescope with flat double sided mirrors that focus in one dimension and utilize a coded mask for resolution in the other. Their positioning accuracy is about an arc minute. The two remaining modules are made from the same materials but configured as a Kirkpatrick-Baez telescope with longer focal length that focuses in two dimensions. When pointed it refines the hybrid telescope's arc minute positions to an arc second and provides larger effective area for spectral and temporal measurements. Above 10 keV the mirrors act as an imaging collimator with positioning capability. For short duration events this hybrid focusing/coded mask system is more sensitive and versatile than either a 2D coded mask or a 2D lobster-eye telescope. Very wide field X-ray telescopes have become feasible as the ability to fabricate large area arrays of CCD and CMOS detectors has improved. This instrument's function in the soft X-ray band is similar to that of Swift in hard X-ray band and there are a greater variety of fast transients in the soft X-ray band. An instrument with considerably more sensitivity than current wide field X-ray detectors would be compatible with a modest NASA Explorer mission.

description: We study the nature of the quasiinvariants in nematic 5CB and measure their relaxation times by encoding the multiple quantum coherences of the states following the JB pulse pair on two orthogonal bases, Z and X. The experiments were also performed in powder adamantane at 301 K which is used as a reference compound having only one dipolar quasiinvariant. We show that the evolution of the quantum states during the build up of the quasi-equilibrium state in 5CB prepared under the S condition is similar to the case of adamantane and that their quasi-equilibrium density operators have the same tensor structure. In contrast, the second constant of motion, whose explicit operator form is not known, involves a richer composition of multiple quantum coherences on the X basis of even order, in consistency with the truncation inherent in its definition. We exploited the exclusive presence coherences 4, 6, 8, besides 0 and 2 under the W condition to measure the spin-lattice relaxation time T_{W} accurately, so avoiding experimental difficulties that usually impair dipolar order relaxation measurement such as Zeeman contamination at high fields, and also superposition of the different quasiinvariants. This procedure opens the possibility of measuring the spin-lattice relaxation of a quasiinvariant independent of the Zeeman and S reservoirs, so incorporating a new relaxation parameter useful for studying the complex molecular dynamics in mesophases. In fact, we report the first measurement of T_{W} in a liquid crystal at high magnetic fields. The comparison of the obtained value with the one corresponding to a lower field (16 MHz) points out that the relaxation of the W-order strongly depends on the intensity of the external magnetic field, similarly to the case of the S reservoir, indicating that the relaxation of the W-quasiinvariant is also governed by the cooperative molecular motions.

Il sociogramma in classe

Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)

description: Il clima di lavoro all’interno di una classe è fortemente condizionato dalla qualità delle relazioni: è compito di tutti entrare in relazioni autentiche con le persone e partecipare alla vita di classe per creare un clima accogliente e un ambiente favorevole all’apprendimento. La capacità di collaborazione, il rispetto reciproco, la voglia di stare insieme e di lavorare per un obiettivo comune, sono degli aspetti che un docente deve curare per favorire l’apprendimento e la crescita personale dei suoi allievi. Per capire le dinamiche relazionali all’interno della classe sono stati impiegati i sociogrammi: dei diagrammi nei quali si mettono in evidenza le relazioni di rifiuto, di attrazione e di indifferenza che intercorrono all’interno di un gruppo di persone in un dato momento, creati sulla base di domande specifiche sottoposte tramite dei questionari. Una volta stabilita la rete di relazioni, sono state progettate delle attività didattiche che valorizzassero le buone relazioni e che sviluppassero le capacità di collaborazione tra gli allievi. Sono stati elaborati dei sociogrammi prima e dopo le attività didattiche, ma non si sono riscontrati risultati significativi. Questo può essere dovuto al poco tempo intercorso tra la somministrazione dei due questionari e dal fatto che questi presentassero un vincolo di tre nominativi per ogni risposta. Relatori: Alberto Crescentini, Luca Sciaroni. Materie: Inglese/Italiano.

Revisiting the radio interferometer measurement equation. II. Calibration and direction-dependent effects

Publisher: name: arXiv
Year: 2011
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: Paper I of the series re-derived the radio interferometry measurement equation (RIME) from first principles, and extended the Jones formalism to the full-sky case, incorporating direction-dependent effects (DDEs). This paper aims to describe both classical radio interferometric calibration (selfcal and related methods), and the recent developments in the treatment of DDEs, using the RIME-based mathematical framework developed in Paper I. It also aims to demonstrate the ease with which the various effects can be described and understood. The first section of this paper uses the RIME formalism to describe self-calibration, both with a full RIME, and with the approximate equations of older software packages, and shows how this is affected by DDEs. The second section gives an overview of real-life DDEs and proposed methods of dealing with them. This results in a formal RIME-based description and comparison of existing and proposed approaches to the problem of DDEs.

description: We present a detailed study of the two-parton light-cone distribution amplitudes for $1\,^3P_2$ nonet tensor mesons. The asymptotic two-parton distribution amplitudes of twist-2 and twist-3 are given. The decay constants $f_T$ and $f_T^\bot$ defined by the matrices of non-local operators on the lightcone are estimated using the QCD sum rule techniques. We also study the decay constants for $f_2(1270)$ and $f_2^\prime(1525)$ based on the hypothesis of tensor meson dominance together with the data of $Γ(f_2\to ππ)$ and $Γ(f'_2\to K\bar K)$ and find that the results are in accordance with the sum rule predictions.

description: We obtain a first non-trivial estimate for the sum of dilates problem in the case of groups of prime order, by showing that if $t$ is an integer different from $0, 1$ or -1 and if $\A \subset \Zp$ is not too large (with respect to $p$), then $|\A+t\cdot \A|>(2+ \vartheta_t)|\A|-w(t)$ for some constant $w(t)$ depending only on $t$ and for some explicit real number $\vartheta_t >0$ (except in the case $|t|=3$). In the important case $|t|=2$, we may for instance take $\vartheta_2=0.08$.
