The origin of the accelerated expansion of the universe is still unclear and new physics is needed on cosmological scales. We propose and test a novel interpretation of dark energy as originated by an elastic strain due to a cosmic defect in an otherwise Euclidean space-time. The strain modifies the expansion history of the universe. This new effective contribution tracks radiation at early tim...

Molecular-dynamics simulation is used to explore the influence of thermal and mechanical history of typical glassy polymers on their deformation. Polymer stress-strain and energy-strain developments have been followed for different deformation velocities, also in closed extension-recompression loops. The latter simulate for the first time the experimentally observed mechanical rejuvenation and ...

remains unclear, but given the patient’s history, a direct crossborder origin could be excluded. Since the blaIMP-19-carrying plasmid could not be mobilized, its contribution in terms of carriage of additional resistance genes could not be assessed and further investigations will be necessary to understand the potential advantage conferred by acquisition of this plasmid by the VIM-producing str...

Transformation frequency by simian papovavirus 40 of fibroblasts from a lung cancer patient with Klinefelter's syndrome and XY/XXY mosaicism was 3 to 10 times higher than that of fibroblasts from individuals with normal karyotypes and no history of cancer. The patient's XXY cell strain also manifested a 3-fold increase in susceptibility to transformation as compared to his XY cell strain. This ...

This study describes a clinical case of a 71-year-old male with a history of ischemic cardiomyopathy after left ventricular assist device (LVAD) endocarditis caused by methicillin-resistant Staphylococcus epidermidis (MRSE) and a rare linezolid-resistant Streptococcus sanguinis strain (MIC, 32 μg/ml). The patient received courses of several antimicrobial agents, including linezolid for 79 days....

The Air Force sponsored flight tests using damage dosimeters, fabricated by The Boeing Company, to measure temperature and structural dynamic strains on B-52, F-15 and C-130 aircraft. The dosimeter measurements help diagnose difficultto-analyze structural conditions, such as acoustics and high cycle fatigue, and support the durability patch design process to repair secondary structure cracks. T...

Propionibacterium acnes is an anaerobic Gram-positive bacterium that forms part of the normal human cutaneous microbiota and is thought to play a central role in acne vulgaris, a chronic inflammatory disease of the pilosebaceous unit (I. Kurokawa et al., Exp. Dermatol. 18:821-832, 2009). Here we present the whole genome sequence of P. acnes type IB strain 6609, which was recovered from a skin s...

The plaque characteristics of 13 field isolates of canine herpesvirus were found to be similar. After 312 passages of the F-205 strain in dog kidney cell cultures incubated at 35 degrees C, the virus still was virulent for newborn pups; it also had the macroplaque morphology of the wild-type virus. However, after 20 additional passages at 30 degrees C, a microplaque (mP) variant had emerged as ...

The microstructure and texture evolution of an AZ31 alloy were investigated after hot rolling subsequent annealing using electron backscatter diffraction (EBSD). First, the was hot-rolled at 350 °C up to low, medium high strain (20, 50 85% thickness reduction, respectively). samples where then annealed for 2, 10 60 min. effect level on corrosion behavior in seawater also evaluated electrochemic...
