Bianchi IX Brane-world Cosmologies [PDF]
We shall investigate the asymptotic properties of the Bianchi type IX cosmological model in the Brane-world scenario. The matter content is assumed to be a combination of a perfect fluid and a minimimally coupled scalar field that is restricted to the ...

Dissonant Representations of Visual Space in Prefrontal Cortex during Eye Movements
Summary: We used local field potentials (LFPs) and spikes to investigate representations of visual space in prefrontal cortex and the dynamics of those representations during eye movements.

Representation and decoding of bilateral arm motor imagery using unilateral cerebral LFP signals
IntroductionIn the field of upper limb brain computer interfaces (BCIs), the research focusing on bilateral decoding mostly based on the neural signals from two cerebral hemispheres. In addition, most studies used spikes for decoding.

Nonlocality of Kohn-Sham exchange-correlation fields in dielectrics
The theory of the macroscopic field appearing in the Kohn-Sham exchange-correlation potential for dielectric materials, as introduced by Gonze, Ghosez and Godby, is reexamined.

ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Coupling between motor cortex and striatum increases during sleep over long-term skill learning
The strength of cortical connectivity to the striatum influences the balance between behavioral variability and stability. Learning to consistently produce a skilled action requires plasticity in corticostriatal connectivity associated with repeated ...

Hiding dark energy transitions at low redshift
We show that it is both observationally allowable and theoretically possible to have large fluctuations in the dark energy equation of state as long as they occur at ultra-low redshifts ...

Mapping the local field potential [PDF]
The local field potential (LFP) is the low-frequency component of the extracellular voltage detected in the cortex, and changes in the LFP have been linked to many important processes, such as memory and motor function. Several recent reports have suggested that the LFP arises from neural activity within a few hundred micrometres of the recording ...

Local Origin of Field Potentials in Visual Cortex [PDF]
The local field potential (LFP) is increasingly used to measure the combined activity of neurons within a region of tissue. Yet, available estimates of the size of this region are highly disparate, ranging from several hundred microns to a few millimeters.

ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...
