Enormous Mushrooms




I found a stand of white toadstools in a yard behind a shop I frequent. I had not seen mushrooms that big in quite a while. In my younger years I was quite a mushroom enthusiast, not for eating them but for finding and identifying them. September is a good time for mushrooms and if it's wet you can find "blooms" of them under trees or in moist areas.

I believe that these mushrooms are Chlorophylla molybdites which is a common species in this area. They are poisonous. If you are unfortunate enough to eat one, you probably won't die but you will be very sick.

I would count myself as a "nature-lover" but not in the romantic sense. I enjoy being out in "natural" environments so that I can analyze and identify species and think about the ecosystem. I think of all the many species of plants and fungi and animals and birds and insects as a vast problem set waiting for me to identify them and find their place in the system. Or else I am there to make sketches, which are also like problems to be solved. My moments of nature bliss or sense of wonder are less frequent than the enjoyment of having identified a bird or mushroom species, or matching a specific shade of sunlit green under the rustling romantic canopy.

High-Performance $hbox{In}_{0.7}hbox{Ga}_{0.3}hbox{As}$ -Channel MOSFETs With High-$kappa$ Gate Dielectrics and $alpha$-Si Passivation
Long and short buried-channel $hbox{In}_{0.7}hbox{Ga}_{0.3}hbox{As}$ MOSFETs with and without $alpha$-Si passivation are demonstrated. Devices with $alpha$-Si passivation show much higher transconductance and an effective peak mobility of 3810 $hbox{cm}^{2}/ hbox{V} cdot hbox{s}$. Short-channel MOSFETs with a gate length of 160 nm display a current of 825 $muhbox{A}/muhbox{m}$ at $V_{g} - V_{t} = hbox{1.6} hbox{V}$ and peak transconductance of 715 $muhbox{S}/muhbox{m}$. In addition, the virtual source velocity extracted from the short-channel devices is 1.4–1.7 times higher than that of Si MOSFETs. These results indicate that the high-performance $hbox{In}_{0.7}hbox{Ga}_{0.3} hbox{As}$-channel MOSFETs passivated by an $alpha$ -Si layer are promising candidates for advanced post-Si CMOS applications.

Nanophotonics: Application of Dressed Photons to Novel Photonic Devices and Systems
This paper reviews recent progress in nanophotonics, a novel optical technology proposed by one of the authors (M. Ohtsu). Nanophotonics utilizes the local interaction between nanometric particles via optical near fields. The optical near fields are the elementary surface excitations on nanometric particles, that is, dressed photons that carry the material energy. Of the variety of qualitative innovations in optical technology realized by nanophotonics, this paper focuses on devices and systems. The principles of device operation are reviewed considering the excitation energy transfer via the optical near-field interaction and subsequent dissipation. As representative examples, the principles of a nanophotonic and gate, not gate, and optical nanofountain are described. Experimental results for operating devices using CuCl quantum dots (QDs), InAlAs QDs, and nanorod ZnO double quantum wells are described. Using a systems-perspective approach, the principles of content-addressable memory based on nanophotonic device operations and experimental results are reviewed. The hierarchy of optical near-field interactions is discussed, and its application to a multilayer memory retrieval system is demonstrated.

Chemist tames longstanding electron computation problem
When the University of Chicago's David Mazziotti talks about chemistry, perhaps he is thinking about how the behavior of all of the electrons in a molecule can be anticipated from the behavior of just two of its electrons. (2008-12-11)

A new device for high-pressure freezing of cultured cell monolayer using 10-{micro}m-thin stainless discs as both culture plate and specimen carrier

High-pressure freezing (HPF) has been generally accepted as the most reliable method for cryofixation of biological samples, yielding a deep vitreous freezing. In recent cell biology, mammalian cultured cells are widely used, but HPF of cultured cell monolayer has not reached its full potential. In this study, we developed a new reliable device for HPF of cultured cell monolayer by using a 10-µm-thin stainless disc both as culture plate and specimen carrier. We describe the practical procedure, and demonstrate fine structures of HeLa cells cultured and cryofixed on the stainless discs as results.
