Serpents, Bombardons, and the “Wiener” Tuba : Richard Wagner and the Evolution of the Orchestral Contrabass Labrosone

Through his orchestral experimentation with acoustics and timbre, Richard Wagner is credited with conceptualizing, commissioning, and attempting to integrate several new labrosones into the orchestra. To greater or lesser extents, they all eventually failed to enter mainstream performance practice, but with one notable exception. Today, the contrabass tuba is a compulsory instrument for profession

The History and Future of the Tuba Family : Material-, Resonance-, and Performance-Based Perspectives

This paper proposes an examination of the intersections of materiality, acoustics, and musical performance practice through the prism of instruments of the tuba family.[*] Investigation into the symbiotic relationship between instrumental evolution and performance practice is a crucial facet of any study of timbre and orchestration. The development of musical objects to produce the sound colors de

Brass instruments, techniques, and repertoire in the early twenty-first century

This chapter assess the state of brass instruments and their associated repertoire and performance practices in the early twenty-first century. Technological innovations and manufacturing developments from recent decades are outlined, as well an examination of how performance techniques have evolved and adapted to meet the demands of modern musicians. Finally, an overview is given of contemporary

Proteomic profiling reveals that ESR1 mutations enhance cyclin-dependent kinase signaling

Three quarters of all breast cancers express the estrogen receptor (ER, ESR1 gene), which promotes tumor growth and constitutes a direct target for endocrine therapies. ESR1 mutations have been implicated in therapy resistance in metastatic breast cancer, in particular to aromatase inhibitors. ESR1 mutations promote constitutive ER activity and affect other signaling pathways, allowing cancer cell

Quantification of adaptive immune responses against protein binding interfaces in the streptococcal M1 protein

Bacterial or viral antigens can contain subdominant protein regions that elicit weak antibody responses upon vaccination or infection although there is accumulating evidence that antibody responses against subdominant regions can enhance the protective immune response. One proposed mechanism for subdominant protein regions is binding of host proteins that prevent antibody production against epitop

Prevalence and Predictive Factors for Celiac Disease in Children With Type 1 Diabetes : Whom and When to Screen? A Nationwide Longitudinal Cohort Study of Swedish Children

OBJECTIVE: To examine the prevalence and predictive factors for celiac disease (CD) after a diagnosis of type 1 diabetes (T1D) in children and adolescents, to improve the current screening guidelines.RESEARCH DESIGN AND METHODS: The association between sex, age at T1D diagnosis, HLA, and diabetes autoantibodies, and a diagnosis of CD was examined in 5,295 children with T1D from the Better Diabetes

Photoredox matching of earth-abundant photosensitizers with hydrogen evolving catalysts by first-principles predictions

Photoredox properties of several earth-abundant light-harvesting transition metal complexes in combination with cobalt-based proton reduction catalysts have been investigated computationally to assess the fundamental viability of different photocatalytic systems of current experimental interest. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations using several GGA (BP86, B

Work-integrated learning in managers’ cooperative work practices

Purpose: This paper aims to focus on academic library managers’ learning practices in the context of cooperative work supported by computational artefacts. Academic library managers’ everyday work is mainly cooperative. Their cooperation is supported predominantly by computational artefacts. Learning how to use the computational artefacts efficiently and effectively involves understanding the chan

Low-grade inflammation in persons with recently diagnosed type 2 diabetes : The role of abdominal adiposity and putative mediators

Aims: To determine the magnitude of the association between abdominal adiposity and low-grade inflammation in persons with recently diagnosed type 2 diabetes (T2D) and to determine to what extent this association is mediated by low physical activity level, hyperinsulinaemia, hyperglycaemia, dyslipidaemia, hypertension, and comorbidities. Materials and Methods: We measured waist circumference, clin

Diagnostic accuracy of prenatal ultrasound in coarctation of aorta : systematic review and individual participant data meta-analysis

Objective: To determine the diagnostic accuracy of prenatal ultrasound in detecting coarctation of the aorta (CoA). Methods: An individual participant data meta-analysis was performed to report on the strength of association and diagnostic accuracy of different ultrasound signs in detecting CoA prenatally. MEDLINE, EMBASE and CINAHL were searched for studies published between January 2000 and Nove

Animal migration in the Anthropocene : threats and mitigation options

Animal migration has fascinated scientists and the public alike for centuries, yet migratory animals are facing diverse threats that could lead to their demise. The Anthropocene is characterised by the reality that humans are the dominant force on Earth, having manifold negative effects on biodiversity and ecosystem function. Considerable research focus has been given to assessing anthropogenic im

Management and documentation of pneumonia–a comparison of patients consulting primary care and emergency care

Patients may attend either primary or emergency care without referral in Sweden. Guidelines recommend a severity assessment, including assessment of vital signs, to be performed for all patients presenting with suspected pneumonia. Objective: To compare management and documentation of vital signs, symptoms and infection severity in pneumonia patients seeking primary care and emergency care without

Food safety and toxicology : Uncertainty analysis in human risk assessment from chemical exposure

Uncertainty analysis should be an integral part of conducting a scientific investigation of the damaging human health effects of exposure to chemicals. Sources of uncertainty related to limitations in knowledge are present in all steps of a such risk assessment, i.e. the hazard identification, hazard characterization and exposure assessment. The purpose of uncertainty analysis is to evaluate the c

Deficiency of the Heterogeneous Nuclear Ribonucleoprotein U locus leads to delayed hindbrain neurogenesis

Genetic variants affectingHeterogeneousNuclear RibonucleoproteinU (HNRNPU) have been identified in several neurodevelopmental disorders (NDDs). HNRNPU is widely expressed in the human brain and shows the highest postnatal expression in the cerebellum. Recent studies have investigated the role of HNRNPU in cerebral cortical development, but the effects of HNRNPU deficiency on cerebellar development

Seasonal movements of Black Coucals Centropus grillii in Nigeria

The scale of movement associated with the migration of many intra-African bird species is still poorly known even with the increasing availability of tracking devices. In this study, we tracked the movements of Black Coucals Centropus grillii breeding in Nigeria from late July using satellite telemetry. Individuals remained on the breeding site for several months; two individuals transmitted after

The genome sequence of the Brown Argus, Aricia agestis (Denis & Schiffermüller, 1775)

We present genome assemblies from two male Aricia agestis specimens (the Brown Argus; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The genome sequences are 435.3 and 437.4 megabases in span. Each assembly is scaffolded into 23 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genomes were assembled and are 15.47 and 15.45 kilobases in length. Gene annotation of these
