The Image of the Artist (Albert Varga)

Installation för Art Encounters Biennale I Timisoara - verket kommer att presenteras i september 2019. Forskning pågår kring målaren Albert Varga (1900-1940) som kommer att redovisas som en del av konstverket.

Crosstalk among hormones in barley spike contributes to the yield

Key message: The hormonal ratios along the barley spike regulate the development, atrophy and abortion of the spikelets and could be the mechanism by which the barley spike adapts its yield potential. Abstract: Barley (Hordeum vulgare L.) is one of the oldest cereal crops known to be cultivated since about 10,000 years. The inflorescence of cultivated barley is an indeterminate spike that produces

Recent Results and Future Plans at MAX-lab

Recent results obtained for the 4He(γ,n) reaction prior to the facility upgrade are presented. Future plans for measuring Compton scattering from the deuteron at the upgraded facility are discussed.

The solvability and subellipticity of systems of pseudodifferential operators

The paper studies the local solvability and subellipticity for square systems of principal type. These are the systems for which the principal symbol vanishes of first order on its kernel. For systems of principal type having constant characteristics, local solvability is equivalent to condition (Ψ) on the eigenvalues. This is a condition on the sign changes of the imaginary part along the oriente

Spatiotemporal flame mapping in a large-bore marine diesel engine using multiple high-speed cameras

A calibrated multiple high-speed camera arrangement recording the flame emission from three different directions has been demonstrated on an engine. From the multiple views, the flame position inside the engine cylinder can be spatially mapped, allowing quantitative studies of the dynamics of ignition, flame development and propagation. Through space carving, the three-dimensional flame contour ca

Vertical drift chambers for the Hall A high-resolution spectrometers at Jefferson Lab

The High-Resolution Spectrometers in Hall A at Jefferson Laboratory have been instrumented with state-of-the-art Vertical Drift Chambers designed and constructed by the Nuclear Interactions Group at MITLNS in conjunction with the Physics Division at Jefferson Lab. These chambers rely on a unique, high cell-density design made possible by the absence of field-shaping wires. Each chamber has an inhe

Historical climate changes and hybridization shaped the evolution of Atlantic Forest spinetails (Aves : Furnariidae)

Combining phylogeographic approaches and hybrid zone inference in a single framework is a robust way to depict respectively the biogeographic history of lineages and the evolutionary processes responsible for speciation. Here, we studied the spatiotemporal patterns of diversification and characterize the hybrid zone between two Atlantic Forest spinetails (Synallaxis ruficapilla and Synallaxis cine

Modelling CO2 weather-why horizontal resolution matters

Climate change mitigation efforts require information on the current greenhouse gas atmospheric concentrations and their sources and sinks. Carbon dioxide (CO2) is the most abundant anthropogenic greenhouse gas. Its variability in the atmosphere is modulated by the synergy between weather and CO2 surface fluxes, often referred to as CO2 weather. It is interpreted with the help of global or regiona
