Schriften zu Kunst und Film

This volume contains previously unpublished writings and hardly known texts of the philosopher, writer and intellectual Günther Anders (1902-92) on art and film. The writings date from the 1920s and 1930s, from Andersʼ years in exile in Paris (1933-36) and the USA (1936-50), especially from his years in Hollywood (1939-43), as well as from the post-war period up to the 1950s. These writings from the authorʼs estate are not only an important source for art and cultural studies, but also put a new complexion on Andersʼ oeuvre, in particular on his famous criticism of mass media from the first volume of his main work “The Outdatedness of Man” from 1956 (“The World as a Phantom and Matrix”).Dieser Band versammelt erstmals bislang unveröffentlichte Schriften und verstreut publizierte Texte des Philosophen, Schriftstellers und streitbaren Intellektuellen Günther Anders (1902-92) zu Kunst und Film. Die Arbeiten stammen aus den 1920er und 1930er Jahren, aus Anders’ Emigrationszeit in Paris (1933-36) und den USA (1936-50), insbesondere aus seiner Zeit in Hollywood (1939-43), sowie aus der unmittelbaren Nachkriegszeit bis in die 1950er Jahre hinein. Die aus dem Nachlass des Autors edierten Texte sind nicht nur eine wichtige kunst- und kulturwissenschaftliche Quelle, sondern erlauben auch einen neuen Blick auf Anders’ Gesamtwerk, insbesondere auf seine viel rezipierte Medienkritik aus dem ersten Band seines Hauptwerks „Die Antiquiertheit des Menschen“ aus dem Jahr 1956 („Die Welt als Phantom und Matrize“)

A practical approach to determine minimal quantum gate durations using amplitude-bounded quantum controls

We present an iterative scheme to estimate the minimal duration in which a quantum gate can be realized while satisfying hardware constraints on the control pulse amplitudes. The scheme performs multiple numerical optimal control cycles to update the gate duration based on the resulting energy norm of the optimized pulses. We provide multiple numerical examples that each demonstrate fast convergence towards a gate duration that is close to the quantum speed limit, given the control pulse amplitude bound

A systematic review of the tribes Hyphydrini Sharp and Pachydrini n. trib. (Coleoptera, Dytiscidae)

Based on a phylogenetic study using adult morphology, the tribe Hyphydrini is redefined as including the following 12 genera: Andex Sharp, Coelhydrus Sharp, Darwinhydrus Shnp, Hydropeplus Sharp, Primospes Sharp, Hyphovatus Wewalka & Biström, Agnoshydrus n. gen. (contains two species: A. laccophiloides (Régimbart) and A. densus n. sp.), Microdytes J. Balfour-Browne, Allopachria Zimmermann, Hyphydrus Illiger, Hovahydrus Biström, and Desmopachria Babington. The two genera Heterhydrus Fairmaire and Pachydrus Sharp are transferred to Pachydrini n. trib. All genera in the two tribes are reviewed including descriptions and check lists. The phylogenetic analysis provided support for the monophyly of each of the genera Allopachria and Desmopachria, whereas that of Microdytes, Hyphydrus and Hovahydrus is considered doubtful. An identification key is provided for the genera and subgenera of both tribes. The following n. comb. are given: Microdytes pasiricus (Csiki, 1938) previously in Hydrovatus and Agnoshydrus laccophiloides (Régimbart, 1888) previously in Microdytes

Skin conductance variability and stressful exposures in critical care

Numerous stressors affect the intensive care unit (ICU) patient. The ICU environment is busy and noisy, with monitoring and treatment around the clock. ICU patients may have problems in getting some sleep, due to lighting and noise. Many ICU survivors report having pain during their ICU stay. Stressful experiences from the ICU contribute to later development of posttraumatic stress symptoms. The comfort and well-being of ICU patients is today an important goal and methods and strategies to achieve this are developing. In this thesis, two areas related to ICU patient exposures were evaluated: noise and pain. A method of monitoring skin conductance variability (SCV) was evaluated. In Paper I, we compared sound pressure levels in three different ICU room types and three different shifts, as well as analysed the sources of disruptive sounds in the different room types. We found that sound pressure levels were similar in the different room types, with a trend towards lower night-time levels. Levels were well above international recommendations. Disruptive sounds were more frequent in three-bed rooms than in singlebed rooms. Main disruptive ICU sounds were from machine alarms and from noisy chatting. In Paper II, we studied SCV as a measure of pain in 40 ICU patients. Increasing levels of stimulation was associated with elevation of SCV. In non-intubated patients, there was an interaction effect between pain and agitation on SCV. In Paper III, we monitored 18 volunteers with SCV and exposed them to a standardised pain stimulus, to pictures with varying emotional content and to an ICU sound recording, in random combinations. SCV was significantly elevated by pain stimulation and to a lesser extent affected by emotion-inducing pictures or ICU sound. In Paper IV, 30 recently discharged ICU patients were monitored with SCV and exposed to the same ICU sound recording as in study III. During SCV monitoring, patients were also asked questions regarding traumatic experiences from the ICU. SCV was significantly elevated in most patients in response to both ICU sounds and questions. There was, however no correlation with stress symptoms assessed with a specific questionnaire for ICU survivors. In conclusion, the studies of this thesis show that a) sound levels preclude normal sleep and can potentially be modifying machine alarms and behaviour b) skin conductance variability may be difficult to interpret in awake patients but potentially has a room for monitoring pain in poorly communicable patients. Further studies in poorly communicable ICU patients during interventions may further elucidate the role of such monitorin

Design of an 845-nm GaAs vertical-cavity silicon-integrated laser with an intracavity grating for coupling to a SiN waveguide circuit

A short-wavelength hybrid GaAs vertical-cavity silicon-integrated laser (VCSIL) with in-plane waveguide coupling has been designed and optimized using numerical simulations. A shallow etched silicon nitride (SiN) grating is placed inside the cavity of the hybrid vertical-cavity silicon-integrated laser to both set the polarization state of the resonant optical field and to enable output coupling to a SiN waveguide with high efficiency. The numerical simulations predict that for apertures of 4 and 6-μm oxide-confined VCSILs operating at 845-nm wavelength, a slope efficiency for the light coupled to the waveguide of 0.18 and 0.22 mW/mA is achievable, respectively, while maintaining a low threshold gain of 583 and 589 cm−1, respectively, for the lasing

X-ray emission from dense plasma in CTTSs: Hydrodynamic modeling of the accretion shock

High spectral resolution X-ray observations of CTTSs demonstrate the presence of plasma at T~2-3X10^6 K and n_e~10^11-10^13 cm^-3, unobserved in non-accreting stars. Stationary models suggest that this emission is due to shock-heated accreting material, but they do not allow to analyze the stability of such material and its position in the stellar atmosphere. We investigate the dynamics and the stability of shock-heated accreting material in CTTSs and the role of the stellar chromosphere in determining the position and the thickness of the shocked region. We perform 1-D HD simulations of the impact of the accretion flow onto chromosphere of a CTTS, including the effects of gravity, radiative losses from optically thin plasma, thermal conduction and a well tested detailed model of the stellar chromosphere. Here we present the results of a simulation based on the parameters of the CTTS MP Mus. We find that the accretion shock generates an hot slab of material above the chromosphere with a maximum thickness of 1.8X10^9 cm, density n_e~10^11-10^2 cm^-3, temperature T~3X10^6 K and uniform pressure equal to the ram pressure of the accretion flow (~450 dyn cm^-2). The base of the shocked region penetrates the chromosphere and stays where the ram pressure is equal to the thermal pressure. The system evolves with quasi-periodic instabilities of the material in the slab leading to cyclic disappearance and re-formation of the slab. For an accretion rate of ~10^-10 M_sun yr^-1, the shocked region emits a time-averaged X-ray luminosity L_X~7X10^29 erg s^-1, which is comparable to the X-ray luminosity observed in CTTSs of the same mass. Furthermore, the X-ray spectrum synthesized from the simulation matches in detail all the main features of the O VIII and O VII lines of the star MP Mus.Comment: Accepted for publication as a Letter in Astronomy & Astrophysic
