description: We construct the Supersymmetric Effective Field Theory of Inflation, that is the most general theory of inflationary fluctuations when time-translations and supersymmetry are spontaneously broken. The non-linear realization of these invariances allows us to define a complete SUGRA multiplet containing the graviton, the gravitino, the Goldstone of time translations and the Goldstino, with no auxiliary fields. Going to a unitary gauge where only the graviton and the gravitino are present, we write the most general Lagrangian built out of the fluctuations of these fields, invariant under time-dependent spatial diffeomorphisms, but softly-breaking time diffeomorphisms and gauged SUSY. With a suitable Stückelberg transformation, we introduce the Goldstone boson of time translation and the Goldstino of SUSY. No additional dynamical light field is needed. In the high energy limit, larger than the inflationary Hubble scale for the Goldstino, these fields decouple from the graviton and the gravitino, greatly simplifying the analysis in this regime. We study the phenomenology of this Lagrangian. The Goldstino can have a non-relativistic dispersion relation. Gravitino and Goldstino affect the primordial curvature perturbations at loop level. The UV modes running in the loops generate three-point functions which are degenerate with the ones coming from operators already present in the absence of supersymmetry. Their size is potentially as large as corresponding to $f_{\rm NL}^{\rm equil.,\,orthog.}\sim 1$ or, for particular operators, even $\gg 1$. The non-degenerate contribution from modes of order $H$ is estimated to be very small.

description: SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) is a grating spectrometer in the UV-Vis-NIR spectral range on-board EnviSat (2002-2012). SCIAMACHY observes Earth’s atmosphere in nadir, limb and occultation geometry. The throughput of the instrument is monitored end-to-end by regular observations of the sun and the internal white light source (WLS). A new (scan-angle dependent) degradation correction is implemented as a joint effort of SRON (scanner model and algorithm prototype), IUP Bremen (operational m-factors) and MF-ATP-DLR (implementation into the L0-1b processor). Described by this technical note is the setup of the operational m–factor calculation, implemented for the next L0-L1b processor version (Version 8). For the degradation correction of Version 8, the radiometric (and the polarization) calibration approach has been changed. Both are split in a scanner unit part and an optical bench module (OBM, including the detectors) part. The scanner unit is described by a physical model of its components, which includes contamination layers on top of the optical components. The increase of these contamination layers accounts to a large extent for the observed degradation of the instrument.
Fundamental limits for cooling of linear quantum refrigerators

description: We study the asymptotic dynamics of arbitrary linear quantum open systems which are periodically driven while coupled with generic bosonic reservoirs. We obtain exact results for the heat flowing into the network, which are valid beyond the usual weak coupling or Markovian approximations. We prove the validity of the dynamical third law of thermodynamics (Nernst unattainability principle), showing that the ultimate limit for cooling is imposed by a fundamental heating mechanism which becomes dominant at low temperatures: the non resonant creation of pairs of excitations in the reservoirs induced by the driving field. This quantum effect, which is missed in the weak coupling approximation, restores the unattainability principle whose validity was recently challenged.

description: Webinar for the CODATA Early Career Researchers and Alumni Group. Abstract:  Everyone is talking about data stewardship. But what does it really mean? And, especially, what’s in it for me and why should I care? This webinar will cover the very practical aspects of data stewardship: what do people mean by it, why it is important (= the selfish benefits of good data stewardship), and, crucially, where and how to look for help. The session will be interactive, with plenty of time for questions and discussion.

description: A large number of $(α,p)$ and $(α,n)$ reactions are known to play a fundamental role in nuclear astrophysics. This work presents a novel technique to study these reactions with the active target system MUSIC whose segmented anode allows the investigation of a large energy range of the excitation function with a single beam energy. In order to verify the method, we performed a direct measurements of the previously measured reactions $^{17}$O$(α,n)^{20}$Ne, $^{23}$Na$(α,p)^{26}$Mg, and $^{23}$Na$(α,n)^{26}$Al. These reactions were investigated in inverse kinematics using $^{4}$He gas in the detector to study the excitation function in the range of about 2 to 6 MeV in the center of mass. We found good agreement between the cross sections of the $^{17}$O$(α,n)^{20}$Ne reaction measured in this work and previous measurements. Furthermore we have successfully performed a simultaneous measurement of the $^{23}$Na$(α,p)^{26}$Mg and $^{23}$Na$(α,n)^{26}$Al reactions.

description: Background: Recovery is a process involving empowering individuals to take control of their lives and develop meaningful and purposeful life, regardless of whether their mental health symptoms persist. Recovery-oriented practice has been widely implemented, particularly in Anglophone countries, during the past two decades. Mental health recovery in Asia is also moving towards recovery-oriented practice. Little is known about how recovery-oriented interventions originating in the West have been implemented and evaluated in Asian contexts. Objective: This review aimed to identify 1) types of recovery-oriented practice interventions that have been implemented in Asia, 2) how they have been culturally adapted, 3) barriers and facilitators to implementation, and 4) how the interventions have been evaluated. Design: This is an integrative review. Methods: This integrative review followed Whittemore and Knafl's five-stage framework. Six electronic databases (e.g., PsycINFO, MEDLINE, Embase, CINAHL, Web of Science, and the Cochrane Library) were systematically searched from their inception to January 2022 to identify eligible studies published in English language. The key search terms included “mental illness”, “recovery-oriented intervention”, and “Asia”. Studies reporting on implementation and evaluation of recovery-focused interventions in Asian settings were eligible. Quality assessment and narrative synthesis were subsequently undertaken. Results: Thirty-eight studies were included. Seven main types of recovery-oriented intervention were identified: (1) peer programmes; (2) illness management and recovery; (3) individual placement and support; (4) strength model case management; (5) clubhouse model; (6) wellness recovery action plan and (7) psychiatric advance directive, alongside several novel recovery programmes. Studies reported cultural adaptations for language, content, cultural norms, religious beliefs, family, and local context. Barriers to implementation included a poor understanding of recovery concepts and inadequate organisational resources. A range of clinical and personal recovery outcome measures were reported. Conclusions: Recovery-oriented interventions are increasing in Asia, with nearly half of reviewed studies featuring cultural adaptations. However, research is geographically skewed, and more rigorously conducted studies are needed across a wider range of Asian countries.

description: Inklusion, weltgesellschaftliche und interkulturelle Öffnung von Schulen erfordern, dass auch die Bildungsbedarfe derjenigen berücksichtigt werden, die möglicherweise nicht ihr ganzes zukünftiges Leben in Deutschland verbringen werden, also transnational mobil sind. Transnationale Mobilität im diesem Sinn wird in Begriffsdiskussionen zu Transnationalität und Mobilität eingeordnet. Da sich die Bildungssysteme weltweit unterscheiden, müssten bei Mobilität vorausschauend Anschlüsse in andere Systemen vorbereitet werden, während zugleich eine Chancengleichheit im gegenwärtig besuchten System anzustreben ist. Aufbauend auf einem klassischen schultheoretischen Werk (Fend 2009) werden Schulfunktionen ausdifferenziertund Überlegungen angestellt, was beachtet werden muss, wenn der Nationalstaat nicht als einziger Bezugspunkt für gesellschaftliche und individuelle Schulfunktionen gewählt wird. Damit soll das Arbeitspapier sowohl einen Beitrag zur theoretischen Fundierung des Forschungs- und Entwicklungsprojekts Transnationale Mobilität in Schulen leisten als auch zur Weiterentwicklung der Schultheorie.

description: The raw coronagraphic performance of current high-contrast imaging instruments is limited by the presence of a quasi-static speckle (QSS) background, resulting from instrumental non-common path errors (NCPEs). Rapid development of efficient speckle subtraction techniques in data reduction has enabled final contrasts of up to 10-6 to be obtained, however it remains preferable to eliminate the underlying NCPEs at the source. In this work we introduce the coronagraphic Modal Wavefront Sensor (cMWS), a new wavefront sensor suitable for real-time NCPE correction. This pupil-plane optic combines the apodizing phase plate coronagraph with a holographic modal wavefront sensor, to provide simultaneous coronagraphic imaging and focal-plane wavefront sensing using the science point spread function. We first characterise the baseline performance of the cMWS via idealised closed-loop simulations, showing that the sensor successfully recovers diffraction-limited coronagraph performance over an effective dynamic range of +/-2.5 radians root-mean-square (RMS) wavefront error within 2-10 iterations. We then present the results of initial on-sky testing at the William Herschel Telescope, and demonstrate that the sensor is able to retrieve injected wavefront aberrations to an accuracy of 10nm RMS under realistic seeing conditions. We also find that the cMWS is capable of real-time broadband measurement of atmospheric wavefront variance at a cadence of 50Hz across an uncorrected telescope sub-aperture. When combined with a suitable closed-loop adaptive optics system, the cMWS holds the potential to deliver an improvement in raw contrast of up to two orders of magnitude over the uncorrected QSS floor. Such a sensor would be eminently suitable for the direct imaging and spectroscopy of exoplanets with both existing and future instruments, including EPICS and METIS for the E-ELT.

description: Even though visibilization is legitimized as a technology of surveillance, where security is gained through knowledge, its decisive function is not epistemological, but as a mode of torture. How can visibility be violent? If this violence consists in making human beings excessively visible, and if critical filmic research usually involves enhancing visibility, how can it avoid reproducing violence? Are there modes of filmic counterhistoriography that do produce visibility differently, appropriating and reframing ambiguous source materials?

description: A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role in disk evolution by promoting the rapid growth of ice-covered grains. Signatures of the carbon monoxide snow-line (at temperatures of around 20 kelvin) have recently been imaged in the disks surrounding the pre-main-sequence stars TW Hydra and HD163296, at distances of about 30 astronomical units (au) from the star. But the water snow-line of a protoplanetary disk (at temperatures of more than 100 kelvin) has not hitherto been seen, as it generally lies very close to the star (less than 5 au away for solar-type stars). Water-ice is important because it regulates the efficiency of dust and planetesimal coagulation, and the formation of comets, ice giants and the cores of gas giants. Here we report ALMA images at 0.03-arcsec resolution (12 au) of the protoplanetary disk around V883 Ori, a protostar of 1.3 solar masses that is undergoing an outburst in luminosity arising from a temporary increase in the accretion rate. We find an intensity break corresponding to an abrupt change in the optical depth at about 42 au, where the elevated disk temperature approaches the condensation point of water, from which we conclude that the outburst has moved the water snow-line. The spectral behaviour across the snow-line confirms recent model predictions: dust fragmentation and the inhibition of grain growth at higher temperatures results in soaring grain number densities and optical depths. As most planetary systems are expected to experience outbursts caused by accretion during their formation our results imply that highly dynamical water snow-lines must be considered when developing models of disk evolution and planet formation.

description: The $^{23}$Na$(α,p)^{26}$Mg and $^{23}$Na$(α,n)^{26}$Al reactions are important for our understanding of the $^{26}$Al abundance in massive stars. The aim of this work is to report on a direct and simultaneous measurement of these astrophysically important reactions using an active target system. The reactions were investigated in inverse kinematics using $^{4}$He as the active target gas in the detector. We measured the excitation functions in the energy range of about 2 to 6 MeV in the center of mass. We have found that the cross sections of the $^{23}$Na$(α,p)^{26}$Mg and the $^{23}$Na$(α,n)^{26}$Al reactions are in good agreement with previous experiments, and with statistical model calculations.

description: A hybrid C/O/Ne white dwarf (WD) -- an unburned C/O core surrounded by an O/Ne/Na mantle -- can be formed if the carbon flame is quenched in a super-AGB (SAGB) star or white dwarf merger remnant. We show that this segregated hybrid structure becomes unstable to rapid mixing within 2,000 years of the onset of WD cooling. Carbon burning includes a weak reaction that removes electrons, resulting in a lower electron-to-baryon ratio ($Y_{\rm e}$) in the regions processed by carbon burning compared to the unburned C/O core, making the O/Ne mantle denser than the C/O core as the WD cools. This is unstable to efficient mixing. We use the results of $\texttt{MESA}$ models with different size C/O cores to quantify the rate at which the cores mix with the mantle as they cool. In all cases, we find that the WDs undergo significant core/mantle mixing on timescales shorter than the time available to grow the WD to the Chandrasekhar mass ($M_{\rm Ch}$) by accretion. As a result, hybrid WDs that reach $M_{\rm Ch}$ due to later accretion will have lower central carbon fractions than assumed thus far. We briefly discuss the implications of these results for the possibility of Type Ia supernovae from hybrid WDs.

Our decoder is constructed from a stochastic neural network called a Boltzmann machine, of the type extensively used in deep learning. We provide a general prescription for the training of the network and a decoding strategy that is applicable to a wide variety of stabilizer codes with very little specialization. We demonstrate the neural decoder numerically on the well-known two dimensional toric code with phase-flip errors.
Protostring Scattering Amplitudes

Year: 2016
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We calculate some tree level scattering amplitudes for a generalization of the protostring, which is a novel string model implied by the simplest string bit models. These bit models produce a lightcone worldsheet which supports $s$ integer moded Grassmann fields. In the generalization we supplement this Grassmann worldsheet system with $d=24-s$ transverse coordinate worldsheet fields. The protostring corresponds to $s=24$ and the bosonic string to $s=0$. The interaction vertex is a simple overlap with no operator insertions at the break/join point. Assuming that $s$ is even we calculate the multi-string scattering amplitudes by bosonizing the Grassmann fields, each pair equivalent to one compactified bosonic field, and applying Mandelstam's interacting string formalism to a system of $s/2$ compactified and $d$ uncompactified bosonic worldsheet fields. We obtain all amplitudes for open strings with no oscillator excitations and for closed strings with no oscillator excitations and zero winding number. We then study in detail some simple special cases. Multi-string processes with maximal helicity violation have much simplified amplitudes. We also specialize to general four string amplitudes and discuss their high energy behavior. Most of these models are not covariant under the full Lorentz group $O(d+1,1)$. The exceptions are the bosonic string whose Lorentz group is $O(25,1)$ and the protostring whose Lorentz group is $O(1,1)$. The models in between only enjoy an $O(1,1)\times O(d)$ spacetime symmetry.

description: We propose a method to study the time evolution of correlated electrons driven by an harmonic perturbation. Combining Floquet formalism to include the time-dependent field and Cluster Perturbation Theory to solve the many-body problem in the presence of short-range correlations, we treat the electron double dressing - by photons and by e-e interaction - on the same footing. We apply the method to an extended Hubbard chain at half occupation and we show that in the regime of small field frequency and for given values of field strength the zero-mode Floquet band is no more gapped and the system recovers a metallic state. Our results are indicative of an omnipresent mechanism for insulator-to-metal transition in 1D systems.

description: The diversity of characteristics for the host of recently discovered exoplanets opens up a great deal of fertile new territory for geophysical fluid dynamics, particularly when the fluid flow is coupled to novel thermodynamics, radiative transfer or chemistry. In this paper, we survey one of these new areas-the climate dynamics of atmospheres with a non-dilute condensible component, defined as the situation in which a condensible component of the atmosphere makes up a substantial fraction of the atmospheric mass within some layer. Non-dilute dynamics can occur for a wide range of condensibles, generically applying near both the inner and the outer edges of the conventional habitable zone and in connection with runaway greenhouse phenomena. It also applies in a wide variety of other planetary circumstances. We first present a number of analytical results developing some key features of non-dilute atmospheres, and then show how some of these features are manifest in simulations with a general circulation model adapted to handle non-dilute atmospheres. We find that non-dilute atmospheres have weak horizontal temperature gradients even for rapidly rotating planets, and that their circulations are largely barotropic. The relative humidity of the condensible component tends towards 100% as the atmosphere becomes more non-dilute, which has important implications for runaway greenhouse thresholds. Non-dilute atmospheres exhibit a number of interesting organized convection features, for which there is not yet any adequate theoretical understanding.

description: It is a challenge to empirically investigate rapidly developing situations. An economic crisis is such a situation in which firms exit, enter, and create new business models. The current pandemic has caused a turbulent situation with hardship, but at the same time with creative potential of innovative change. It calls for empirical analyses, but firm level data based on surveys is hard to collect given the high speed of developments. An alternative data source are news articles reporting on innovation issues and assessed by text mining techniques. This is exemplified in this chapter. It shows how topic modeling can be used to scrutinize the shift of innovation topics since the beginning of the COVID-19 crisis. The results apply to a small innovation system in Germany and confirm that innovation priorities change during a crisis and that many different actors are involved.

description: Probing correlations among short and long-wavelength cosmological fluctuations is known to be decisive for deepening the current understanding of inflation at the microphysical level. Spectral distortions of the CMB can be caused by dissipation of cosmological perturbations when they re-enter Hubble after inflation. Correlating spectral distortions with temperature anisotropies will thus provide the opportunity to greatly enlarge the range of scales over which squeezed limits can be tested, opening up a new window on inflation complementing the ones currently probed with CMB and LSS. In this paper we discuss a variety of inflationary mechanisms that can be efficiently constrained with distortion-temperature correlations. For some of these realizations (representative of large classes of models) we derive quantitative predictions for the squeezed limit bispectra, finding that their amplitudes are above the sensitivity limits of an experiment such as the proposed PIXIE.

description: Seit kurzem besteht die Möglichkeit einer Corona-Virus-Impfung. In Deutschland gibt es keine Impfpflicht. Den Bürger*innen wird das Recht auf eine informierte Entscheidung zugesprochen. Ärzt*innen sind verpflichtet vor der Durchführung von invasiven Maßnahmen, die informierte Zustimmung der Patient*innen einzuholen. Diese besteht in der Regel aus einem mündlichen Aufklärungsgespräch und wird auf einem schriftlichen Aufklärungsbogen dokumentiert. Bisherige Forschungsergebnisse deuten darauf hin, dass relevante Informationen in Aufklärungsbögen fehlen, die eine informierte Entscheidung ermöglichen. Das Studienprotokoll beschreibt das methodische Vorgehen für die systematische Suche nach Aufklärungsbögen über die Corona-Virus-Impfung und deren kritische Bewertung. Die Ergebnisse können Implikationen für die Optimierung der Aufklärungsbögen liefern, um Bürger*innen eine informierte Entscheidung für oder gegen die Corona-Virus-Impfung zu ermöglichen.
On the closed embedding of the product of theta divisors into product of Jacobians and Chow groups

description: In this article we generalize the injectivity of the push-forward homomorphism at the level of Chow groups, induced by the closed embedding of $\Sym^m C$ into $\Sym^n C$ for $m\leq n$, where $C$ is a smooth projective curve, to symmetric powers of a smooth projective variety of higher dimension. We also prove the analog of this theorem for product of symmetric powers of smooth projective varieties. As an application we prove the injectivity of the push-forward homomorphism at the level of Chow groups, induced by the closed embedding of self product of theta divisor into the self product of the Jacobian of a smooth projective curve.

Auf die Haltung kommt es an! : ein Essay zur Relevanz einer professionellen Haltung für die Umordnung von Bildungsprozessen im Kontext von Migration und Transnationalität

description: Dieses TraMiS-Arbeitspapier, das die Form eines Essays hat, will Impulse für die Entwicklung einer differenzsensiblen und diskriminierungskritischen Haltung von Lehrer*innen in der Schule im Kontext von Transnationalität und Migration geben. Praktische Beispiele aus dem Schulalltag zum Umgang mit Mehrsprachigkeit, Transnationalität und religiöser Pluralität verdeutlichen, wie wichtig eine differenzsensible und diskriminierungskritische Haltung für eine respektvolle Interaktion mit Schüler*innen ist. Der Reflexion über die im Schulalltag oft unbewusst artikulierten Einstellungen und Annahmen über eine migrationsbedingte Besonderung von Schüler*innen kommt hierbei eine wichtige Rolle zu. Für die Anbahnung einer solchen Reflexion können allgemeine erziehungswissenschaftliche Diskurse zu Haltung als zentralem Bestandteil pädagogischer Professionalität herangezogen werden, die dieser Beitrag in einer migrationsgesellschaftlichen Perspektive weiterentwickelt. Danach müssen sich Lehrer*innen auch mit gesellschaftspolitischen Diskursen zu Migration und Bildung auseinandersetzen, weil sie darin zwangsläufig involviert sind. Nur wenn sie sich verdeutlichen, wie ihre eigene Wahrnehmung gesellschaftlich beeinflusst wird und wie sie selbst wahrgenommen werden, können sie die Offenheit und Sensibilität erwerben, die sie brauchen, um den Bildungsbedürfnissen und -interessen ihrer Schüler*innen pädagogisch professionell gerecht zu werden.
Approximate but accurate quantum dynamics from the Mori formalism: II. Equilibrium correlation functions

description: The ability to efficiently and accurately calculate equilibrium time correlation functions of many-body condensed phase quantum systems is one of the outstanding problems in theoretical chemistry. The Nakajima-Zwanzig-Mori formalism coupled to the self-consistent solution of the memory kernel has recently proven to be highly successful for the computation of nonequilibrium dynamical averages. Here, we extend this formalism to treat symmetrized equilibrium time correlation functions for the spin-boson model. Following the first paper in this series [A. Montoya-Castillo and D. R. Reichman, J. Chem. Phys. $\bf{144}$, 184104 (2016)], we use a Dyson-type expansion of the projected propagator to obtain a self-consistent solution for the memory kernel that requires only the calculation of normally evolved auxiliary kernels. We employ the approximate mean-field Ehrenfest method to demonstrate the feasibility of this approach. Via comparison with numerically exact results for the correlation function $\mathcal{C}_{zz}(t) = \mathrm{Re}\langle σ_z(0)σ_z(t)\rangle$, we show that the current scheme affords remarkable boosts accuracy and efficiency over bare Ehrenfest dynamics. We further explore the sensitivity of the resulting dynamics to the type of kernel closures and the accuracy of the initial canonical density operator.

description: We present a new multi-pixel high resolution (R >10^7) spectrometer for the Stratospheric Observatory for Far-Infrared Astronomy (SOFIA). The receiver uses 2 x 7-pixel subarrays in orthogonal polarization, each in an hexagonal array around a central pixel. We present the first results for this new instrument after commissioning campaigns in May and December 2015 and after science observations performed in May 2016 . The receiver is designed to ultimately cover the full 1.8-2.5 THz frequency range but in its first implementation, the observing range was limited to observations of the [CII] line at 1.9 THz in 2015 and extended to 1.83-2.07 THz in 2016. The instrument sensitivities are state-of-the-art and the first scientific observations performed shortly after the commissioning confirm that the time efficiency for large scale imaging is improved by more than an order of magnitude as compared to single pixel receivers. An example of large scale mapping around the Horsehead Nebula is presented here illustrating this improvement. The array has been added to SOFIA's instrument suite already for ongoing observing cycle 4.
