We study a vertex operator algebra (VOA) V related to the M(3, p) Virasoro minimal series. This VOA reduces in the simplest case p = 4 to the level two integrable vacuum module of ŝl2. On V there is an action of a commutative current a(z), which is an analog of the current e(z) of ŝl2. Our main concern is the subspace W generated by this action from the highest weight vector of V . Using the Fo...

Design in Solid State Synthesis Based on Phase Homologies: A1-xSn9-xBi11+xSe26(A=K, Rb, Cs)-A New Member of the Grand Homologous Series Am[M6Se8]m[M5+nSe9+n] with M=Sn and Bi

There is a strong interest in developing new chemical concepts in designing new materials with superior thermoelectric properties (1, 2). Our approach, which has been outlined in detail elsewhere (3), is focused on complex quaternary and ternary bismuth chalcogenides incorporating alkali metals. The examples of CsBi4Te6 (4), K2Bi8Se13 (5, 6), and K1.25Pb3.5Bi7.25Se15 (7) show that these explora...

1 2 3 4 M 1 and M 4 receptors modulate hippocampal pyramidal neurons 5

31 Acetylcholine (ACh), acting at muscarinic ACh receptors (mAChRs), modulates the 32 excitability and synaptic connectivity of hippocampal pyramidal neurons. CA1 pyramidal 33 neurons respond to transient (" phasic ") mAChR activation with biphasic responses in 34 which inhibition is followed by excitation, whereas prolonged (" tonic ") mAChR activation 35 increases CA1 neuron excitability.
