Alterations of the serotonergic system in the prefrontal cortex (PFC) are implicated in psychiatric disorders such as schizophrenia and depression. Although abnormal synchronous activity is observed in the PFC of these patients, little is known about the role of serotonin (5-HT) in cortical synchrony. We found that 5-HT, released by electrical stimulation of the dorsal raphe nucleus (DRN) in an...

The density of the domestic building stock London is explored, moving from scale individual house and blocks flats, through larger geographical units, to complete boroughs. description highly detailed made using 3DStock method, which derives geometry digital maps LiDAR (laser measurements overflying aircraft). This means that accurate estimates floor areas can be used measure densities as Floor...

The ligand binding domain of glutamate receptors (GluRs) has 2-fold rotational symmetry. The structure including the symmetry of the GluR ion channel remains undefined. Here we used substituted cysteines in the pore-lining M3 segment of the AMPAR GluR-A subunit and various cysteine-reactive agents to study the structure of the channel during gating. We find that cysteines substituted at A+6, lo...

I discuss the rôle of strong final state interactions (FSI) in K → 2π decays. In this case strong FSI effects can be resummed [1,2] by solving the Omnès problem for K → 2π amplitudes. Implications for the CP conserving ∆I = 1/2 ratio and the direct CP violation parameter ε ′ /ε are also discussed.

I give a brief review of final state interactions in meson decays. I describe possible effects of FSI in K, D and B systems, paying particular attention to the description of the heavy meson decays. Available theoretical methods for dealing with the effects of FSI are discussed.

We study substitution tilings that are also discrete plane tilings, is, satisfy a relaxed version of cut-and-projection. prove the Sub Rosa with 2n-fold rotational symmetry for odd $$n>5$$ defined by Kari and Rissanen not planes—and therefore cut-and-project either. then define new Planar any n, show these condition. The we consider edge-to-edge rhombus tilings. give an explicit construction 10...

Aim Discharge is a key determinant of biodiversity in rivers. Positive relationships between riverine and discharge, also called species–discharge (SDRs), have been widely documented. However, potential human influences on these are typically not considered. We aimed to fill this gap by exploring whether how the slopes intercepts global fish SDRs might be affected pressure environment. Location...
