Was macht eine höfisch kultivierte Dame oder einen höfischen Ritter aus? Die mittelalterliche, von Frankreich ausgehende Artusepik antwortet auf diese Frage unter Bezug auf drei Komponenten, nämlich eine edle Abkunft (Geburtsadel), eine edle Gesinnung (Tugendadel) und einen gewissen höfischen Lebensstil, zu dem, ganz zentral, auch höfische Luxus- und Repräsentationsobjekte gehören, so etwa ritterliche Bewaffnung und kostbare Kleidung. Was passiert, wenn es an einer Harmonie von innen und außen öffentlich sichtbar mangelt und die Wirkungseinheit von Mensch und Repräsentationsobjekt zu Bruch geht, zeigt uns die mittelalterliche Erzählung vom schlecht geschnittenen Mantel, altfranzösisch: du mantel mautaillé. Sie nimmt in Frankreich des 13. Jahrhunderts (zwischen 1200 und 1210) ihren Anfang, und zwar in Gestalt des Lais (Le lay du cort mantel), einer kurzen Verserzählung keltischer Stoffe (lai narratif ), und verbreitet sich rasch in Europa.
Living matter is defined by metastability, implying a tightly balanced synthesis and turnover of cellular components. The first step of eukaryotic protein degradation via the ubiquitin-proteasome system (UPS) leads to peptides, which are subsequently degraded to single amino acids by an armada of proteases. A small fraction of peptides, however, escapes further cytosolic destruction and is transported by ATP-binding cassette (ABC) transporters into the endoplasmic reticulum (ER) and lysosomes. The ER-resident heterodimeric transporter associated with antigen processing (TAP) is a crucial component in adaptive immunity for the transport and loading of peptides onto major histocompatibility complex class I (MHC I) molecules. Although the function of the lysosomal resident homodimeric TAPL-like (TAPL) remains, until today, only loosely defined, an involvement in immune defense is anticipated since it is highly expressed in dendritic cells and macrophages. Here, we compare the gene organization and the function of single domains of both peptide transporters. We highlight the structural organization, the modes of substrate binding and translocation as well as physiological functions of both organellar transporters.
Between 28 June and 17 September 2018, 27 cases of human West Nile virus infections were recorded in Austria; four cases of West Nile neuroinvasive disease, 11 cases of West Nile fever, six infections detected by blood donation screening and six imported cases. In addition, 18 cases of human Usutu virus infections (all blood donors) were recorded. This is the highest number of annual infections recorded in Austria since the introduction of both viruses.
Using a data sample of e+e− collision data corresponding to an integrated luminosity of 2.93 fb−1 collected with the BESIII detector at a center-of-mass energy of s=3.773GeV, we search for the singly Cabibbo-suppressed decays D0→π0π0π0, π0π0η, π0ηη and ηηη using the double tag method. The absolute branching fractions are measured to be B(D0→π0π0π0)=(2.0±0.4±0.3)×10−4, B(D0→π0π0η)=(3.8±1.1±0.7)×10−4 and B(D0→π0ηη)=(7.3±1.6±1.5)×10−4 with the statistical significances of 4.8σ, 3.8σ and 5.5σ, respectively, where the first uncertainties are statistical and the second ones systematic. No significant signal of D0→ηηη is found, and the upper limit on its decay branching fraction is set to be B(D0→ηηη)<1.3×10−4 at the 90% confidence level.
Language and the construction of multiple identities in the Nigerian novel examines the multifaceted relation between people and the various identities they construct for themselves and for others through the context-specific ways they use language. Specifically, this book pays attention to how forms of identities ethnic, cultural, national and gender are constructed through the use of language in select novels of Adichie, Atta and Betiang. Employing an interdisciplinary approach, this book draws analytical insights from critical discourse analysis, literary discourse analysis and socio-ethno-linguistic analysis. This approach enables the author to engage with the novels, to illuminate the link between the ways Nigerians use language and the identities they construct. Being a context-driven analysis, this book critically scrutinises literary language beyond stylistic borders by interrogating the micro and macro levels of language use, a core analytical paradigm frequently used by discourse analysts who engage in critical discourse analysis.
The nesting biology of the potter wasp Pachymenes ghilianii (Spinola) (Hymenoptera: Vespidae: Eumeninae) is described based on observations made in the Cerro Turega Hydric Reserve, Penonome, Panama. The collection of building material, the architecture of the nest, the process of building a cell and cell provision with geometrid larvae (Lepidoptera: Geometridae), and the emergence time of the adults are recorded.
A wealth of data has elucidated the mechanisms by which sensory inputs are encoded in the neocortex, but how these processes are regulated by the behavioral relevance of sensory information is less understood. Here, we focus on neocortical layer 1 (L1), a key location for processing of such top-down information. Using Neuron-Derived Neurotrophic Factor (NDNF) as a selective marker of L1 interneurons (INs) and in vivo 2-photon calcium imaging, electrophysiology, viral tracing, optogenetics, and associative memory, we find that L1 NDNF-INs mediate a prolonged form of inhibition in distal pyramidal neuron dendrites that correlates with the strength of the memory trace. Conversely, inhibition from Martinotti cells remains unchanged after conditioning but in turn tightly controls sensory responses in NDNF-INs. These results define a genetically addressable form of dendritic inhibition that is highly experience dependent and indicate that in addition to disinhibition, salient stimuli are encoded at elevated levels of distal dendritic inhibition.
Rationale: With advances in contemporary radiotherapy techniques, and as cancer survival improves, severe isolated coronary ostial disease may develop many years following mediastinal radiotherapy, even in the absence of classical cardiovascular risk factors.
Patient concerns: We describe the case of a 73-year-old woman with previous chest radiotherapy for breast cancer who underwent coronary artery bypass graft surgery for severe bilateral coronary ostial lesions.
Diagnoses: Coronary angiography demonstrated severe, isolated bilateral coronary ostial lesions.
Interventions: The patient underwent urgent coronary artery bypass graft surgery to treat her critical coronary artery disease.
Outcomes: Intra-operatively, internal mammary arteries were not amenable to harvesting due to very dense mediastinal adhesions. Therefore, saphenous vein grafts were performed to the left anterior descending, distal left circumflex, obtuse marginal and distal right coronary arteries. The patient made a satisfactory in-hospital recovery, and was subsequently discharged back to her local hospital for rehabilitation.
Lessons: Patients successfully treated with mediastinal radiotherapy require careful long-term follow-up for the assessment of radiation-induced coronary artery disease. Importantly, mediastinal irradiation may preclude internal mammary artery utilization, and thus alter the strategy for surgical myocardial revascularization.
At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/s. The ALICE High Level Trigger (HLT) system pioneered the use of FPGA- and GPU-based algorithms to reconstruct charged-particle trajectories and reduce the data size in real time. The results of the reconstruction of the collision events, available online, are used for high level data quality and detector-performance monitoring and real-time time-dependent detector calibration. The online data compression techniques developed and used in the ALICE HLT have more than quadrupled the amount of data that can be stored for offline event processing.
