The Melancholy Day




This Monday, September 1, was the day each year I call the "Melancholy Day." It's the last time that the swimming pool outside my apartment building is open. On that day, after a full afternoon of kids splashing as usual, the pool caretakers take in all the white plastic deck chairs and regular chairs, and stack them in the poolhouse for storage. I am glad that I was scheduled to work on Monday, Labor Day, because otherwise I would have to watch this activity. It's sad for me because it means that summer is over.

Now the the pool water will be neglected. As if in some suburban pseudo-Japanese haiku of elegant sadness, a few early yellow leaves will fall onto the undisturbed surface while it is still a glorious aqua color. But in a week or so, algae will build up in the pool and it will turn a murky yellow. The pool people will drain it down a bit, remove the metal ladders around the rim, and pack everything up before they go home to whatever Eastern European country they came from.

September still has some warm times ahead, but all I can think of is being freeze-dried for the winter, stumbling around in my heavy jacket and enduring the mind-numbing torture of the "holiday season." I constantly think of moving to a warmer southern part of the country, but it seems they have a bit of rough weather these days. It's going to be a long eight months before April.

Design and Fabrication of Stretchable Multilayer Self-Aligned Interconnects for Flexible Electronics and Large-Area Sensor Arrays Using Excimer Laser Photoablation
Stretchable interconnects are fabricated on polymer substrates using metal patterns both as functional interconnect layers and as in situ masks for excimer laser photoablation. Single-layer and multilayer interconnects of various designs (rectilinear and “meandering”) have been fabricated, and certain “meandering” interconnect designs can be stretched up to 50% uniaxially while maintaining good electrical conductivity and structural integrity. This approach eliminates masks and microfabrication processing steps as compared to traditional fabrication approaches. Furthermore, this technology is scalable for large-area sensor arrays and electronic circuits, adaptable for a variety of materials and interconnects designs, and compatible with MEMS-based capacitive sensor technology.

Analysis of a Bowtie Nanoantenna for the Enhancement of Spontaneous Emission
A 2-D metallic bowtie nanoantenna, consisting of two nearby metallic nanotriangles and containing a molecule within the gap, is studied for the enhancement of a single emitter's spontaneous emission. For simplicity, a transverse-magnetic model is used for simulation and a set of new surface integral equations is developed for the calculation. The process of spontaneous emission is simply divided into two stages: the first stage is the excitation of the emitter irradiated by an incident plane wave and the second is the emission of the excited emitter. For the latter, the excited emitter is modeled as an electric dipole to interact with the nanoantenna. The results show that a metallic bowtie nanoantenna behaves as a nanolens as well as a polarizer to provide a strong local electric field with a polarization parallel to the axis of the bowtie in the gap for the emitter's excitation, and its quantum yield exhibits a function of a low-pass filter as well as an orientizer for the emitter's emission.

Scripps Research Scientists Shed Light on How DNA Is Unwound So That Its Code Can Be Read
Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body.

Comment on 'Electron holography on dynamic motion of secondary electrons around sciatic nerve tissues'

We present an alternative interpretation of the holographic phase dislocation loops revealed by Shindo et al. [J. Electron Microsc. 56(1): 1–5 (2007)] around a charged sample. Our interpretation does not involve the motion of secondary electrons around a charged object. It relates, instead, to fluctuating charges on the sample and to the resulting Moiré-type patterns in the hologram.
