We design a cosmological model that expands at a speed less than that of free fall and which allows accelerations of the recession velocity. In addition, the underlying geometry of the model can be adjusted in such a way that attractive forces arise in the cosmos, forces whose sources are not matter. This could explain dark matter as a property of space and one could also address the question of why galactic systems are not subject to expansion.

In his contribution,rainer Winter shows how Critical Hermeneutics,as developed by Hans-Herbert Kogler,has deepened our understanding of how agents are anchored in social processes and of their capacity to critically reflect upon these ***,he succeeded in broadening the field of critical theory by combining the anti-positivistic procedure that is hermeneutics with a critical examination of the relations of power and *** doing so,he also refined our understanding of agency and posited "self-empowerment" as an important aspiration.

We calculate the transformation laws of the general linear superfield and chiral superfields under supertranslations to all orders in the translation parameters . We use the superfield formalism with complete expansions of the component fields in the coordinate shifts . The results show in particular how a general supertranslation transforms each component field of a supermultiplet into a complete superfield. The results also provide complete parametri-zations of orbits of component fields under supertranslations.

We raise the question of how the curvature parameter k is related to the curvature of the universe. We also show that, for a cosmological model that can be interpreted geometrically as a pseudo-hypersphere with a time-dependent radius, the Einstein field equations are not sufficient to fully describe the model. In addition, the differential equation system of Bianchi identities is required to describe the temporal evolution of the universe. We discuss the facts using the example of the de Sitter universe, the subluminal universe and the Rh=ct model by Melia. In particular, we discuss the formal differences between the two latter models and claim that both models are identical. We also examine the possibility of introducing non-comoving coordinates.

AIM： To investigate indications, surgical challenges, and outcome of Descemet -membrane endothelial keratoplasty （DMEK） in patients with retinal comorbidities （RC）. METHODS： In a prospective cohort study, 8 eyes of 8 DMEK-patients with known RC were compared to 38 eyes of 38 DMEK-patients without RC. The duration of surgery, the degree of difficulty graded by the surgeon, and the complications through DMEK-surgery were analyzed for each patient. The best-corrected visual acuity （BCVA）, the endothelial cell count, the intraocular pressure, and the subjective satisfaction was evaluated after a 6-month follow-up. Data were compared applying the non-parametric Wilcoxon-, Chi-square- and Fisher＇s-exact-test with P≤ 0. 05 as level of significance. RESULTS： RC-patients had dry age-related macular degeneration （n=4） or history of pars-plana vitrectomy （n=4）. The main indication for DMEK was pain due to bullous keratopathy for the RC-patlents （n=7, 88%） and visual impairment due to Fuchs endothelial keratoplasty for the non-RC-patients （n=33, 87% ）. The BCVA increased for both groups （P=0.01, P〈0.001） and all corneas cleared. For the RC-patients, the subjective satisfaction improved significantly （P=0.02）. Oil-filling and missing support of the vitreous body complicated surgery in vitrectomized eyes. CONCLUSION： DMEK is a favorable technique to treat endothelial disorders even if patients suffer from a retinal comorbidity. By enhancing the corneal clarity, it enables retinal examination or intraocular surgery and increases the patients satisfaction. However, in vitrectomized or silicone-oil filled eyes, the duration of surgery and degree of complexity are increased. An experienced surgeon should perform DMEK in these patients. Clinical trial registration number： DRKS00007566.

We demonstrate an optical switching in a middle infrared continuous-wave quantum cascade laser operated in single mode by illuminating its front facet with a near infrared laser. A decrease in the laser net gain is observed in the amplified spontaneous emission spectrum. This is attributed to an increase of the carrier concentration caused by the near infrared excitation. The net gain reduction allows the quantum cascade laser to be completely switched off from single mode lasing. This optical switching can be used to convert near infrared signals into middle infrared signals for free space communication.

Introduction Taking the One-Dimensional Man as a starting point, I would like to show in the following what an important contribution the work of Herbert Marcuse can make to a critical theory of the present. More than 50 years after its first publication, this book seems more relevant than ever. It allows us to understand how domination is exerted and maintained in late capitalism that is today organized according to neoliberal principals. It also allows us to ask if there can be alternatives to this society. To date, one-dimensionality has proven itself to be a relevant basic concept of critical theory that first of all analyses society critically as it is by revealing the forces that sustain, legitimize and stabilize the existing structures.
