For the assessment of body movements during sleep, a system for monitoring the temperature in bed was developed. The system consists of 16 temperature sensors and a data logger with a memory card. Fifteen of the temperature sensors were arranged in line 6 cm apart on a flat cable. The temperatures at these 15 points in the bed, and the room temperature(More)
Human cells are known to express many chimeric RNAs, i.e. RNAs containing two genes' sequences. Wondering whether there also is trimeric RNA, i.e. an RNA containing three genes' sequences, we wrote simple computer code to screen human expression sequence tags (ESTs) deposited in different public databases, and obtained hundreds of putative trimeric ESTs. We(More)
Toward a complete LC-MS mapping system for peptides and proteins, we have coupled a precision-flow microbore HPLC system to an electrospray single quadrupole mass spectrometer. The HPLC system allows fast separation of protein digests with UV detection at the low pmol level. A 2 microliters/min portion (1:25) of the effluent is passed into a(More)
This paper presents a systematic study on the stability of a two-dimensional vibration isolation floating raft system with a time-delayed feedback control. Based on the generalized Sturm criterion, the critical control gain for the delay-independent stability region and critical time delays for the stability switches are derived. The critical conditions can(More)
The bare magnetic Mn<inf>0.5</inf>Zn<inf>0.5</inf>Fe<inf>2</inf>O<inf>4</inf> nanoparticles were prepared by the hydro-thermal method. The optimized preparation conditions were obtained by the orthogonal experiment. Crystal structure and the grain diameter of the particles were observed by X-ray Diffraction (XRD) and Transmission Electron Microscope (TEM),(More)
The silicon isotope composition of chert has recently been used to study the historic evolution of the global ocean. It has been suggested that Precambrian cherts have much higher δ30Si values than Phanerozoic cherts do and that the former show an increasing trend from 3.5 to 0.85 Ga, reflecting a decrease in ocean temperatures. However, cherts have various(More)
New mass spectrometry techniques, such as electrospray ionization (ESI), allow the study of large biomolecules and peptide mixtures. The data produced are complex and interpretation can be a long and tedious process. A new suite of data-processing software is described which allows many of these operations to be carried out in a rapid, automated way.(More)
Today we would like to discuss some problems involving Long-range reverberation in shallow water. The title of the talk is "Nonreciprocity of Long-range Reverberation in Wedged Continental Shelf". The talk is divided into four parts. First we would like to talk a little bit about the background of current research on long-range reverberation in shallow(More)
In order to assess body movements during sleep, a system which records the temperature on a bed was developed. The system consists of 16 temperature sensors and a data logger with a memory card (RAM card). The 15 temperature sensors were arranged in line with a separation of 6 cm on a flat cable which was placed between the bed sheet and the mattress in(More)
