Direct detection of phycocyanin in sediments by hyperspectral imaging.

Unlabelled: Cyanobacteria are ubiquitous aquatic organisms with a remarkable evolutionary history reaching as far as 1.9 Ga. They play a vital role in ecosystems yet also raise concerns due to their association with harmful algal blooms.

Doxorubicin treatment has a biphasic effect over time on dopamine release and impulsive behavior in Wistar rats.

Doxorubicin (Dox) is a chemotherapy agent commonly used to treat multiple types of cancers and is associated with cognitive impairment. The goal of this work was to determine the effect of Dox treatment on dopamine release and uptake and behavior in rats. Rats received one dose per week of Dox (2.

Interaction between saflufenacil and ammonium glufosinate to control ryegrass.

Annual ryegrass (Lolium multiflorum Lam.) is one of the main weeds in subtropical cropping systems of Europe, Oceania and South America. Therefore, the hypothesis of this work is that the interaction between ammonium glufosinate and saflufenacil can be synergistic for ryegrass control.

The topology of a chaotic attractor in the Kuramoto-Sivashinsky equation.

The Birman-Williams theorem gives a connection between the collection of unstable periodic orbits (UPOs) contained within a chaotic attractor and the topology of that attractor, for three-dimensional systems. In certain cases, the fractal dimension of a chaotic attractor in a partial differential equation (PDE) is less than three, even though that attractor is embedded within an infinite-dimensional space. Here, we study the Kuramoto-Sivashinsky PDE at the onset of chaos.

Human cortical high-gamma power scales with movement rate in healthy participants and stroke survivors.

Motor cortical high-gamma oscillations (60-90 Hz) occur at movement onset and are spatially focused over the contralateral primary motor cortex. Although high-gamma oscillations are widely recognized for their significance in human motor control, their precise function on a cortical level remains elusive. Importantly, their relevance in human stroke pathophysiology is unknown.
