Slow, ~50 ps, P* → P(+)HA(-) electron transfer is observed in Rhodobacter capsulatus reaction centers (RCs) bearing the native Tyr residue at M208 and the single amino acid change of isoleucine at M20...
The short-lived (<1 ps) initial intermediate state P(+)B(L)(-) in the photoinduced charge separation process of the bacterial photosynthetic reaction center has been trapped in two D(LL)-based Rhodoba...
Lateral variations in membrane composition are postulated to play a central role in many cellular events, but it has been difficult to probe membrane composition and organization on length scales of t...
The triplet state of aromatic molecules forms and decays by intersystem crossing, as originally demonstrated by Kasha and Lewis. By contrast, the triplet state of the primary electron donor, 3 P, in p...
Photochemical hole-burning spectra have been obtained for the lowest energy electronic absorption band of the primary electron donor P of photosynthetic reaction centers (RCs) that exhibit different r...
The triplet state of the primary electron donor is formed in bacterial reaction centers when electron transfer to the quinone is blocked. The relative quantum yield of formation and the rate of decay ...
Individual tree species classification can be done using Light Detection and Ranging (LIDAR) and aerial multichannel images simultaneously. LIDAR is typically used to derive shape features and aeria...
The separation of the field produced by different internal sources can be accomplished by means of the so-called spatial spectrum of the geomagnetic field of internal origin. It is shown how such a ra...
For d ≥ 2 we exhibit mixing Zd shifts of finite type and sofic shifts with large entropy but poorly separated subsystems (in the sofic examples, the only minimal subsystem is a single point). These ex...
We present a real-time version of the DUET algorithm forthe blind separation of any number of sources using only two mixtures. The method applies when sources are Wdisjoint orthogonal, that is, when t...
There is increased interest in using microphone arrays in a variety of audio source separation and consequently speech processing applications. In particular, small arrays of two to four microphones a...
We investigate the assumption that sources have disjoint support in the time domain, time-frequency domain, or frequency domain. We call such signals disjoint orthogonal. The class of signals that app...
Few source separation and independent component analysis approaches attempt to deal with noisy data. Weconsider an additive noise mixing model with an arbitrary number of sensors and possibly more sou...
To be applicable in realistic scenarios, blind source separation approaches should deal evenly with non-square cases and the presence of noise. We consider an additive noisemixing model with an arbitr...
Sparse constraints on signal decompositions are justified bytypical sensor data used in a variety of signal processing fields such as acoustics, medical imaging, or wireless, but moreover can lead to ...
