Application of the NEP technique provides a simple, rapid, non-invasive, and reliable test to detect tidal expiratory flow limitation; b) it does not require a body-box or cooperation on the patient’s part; c) it can be applied in any posture, during mechanical ventilation, and during exercise; d) it provides new insights into the physiology and pathophysiology of sev‐ eral diseases and the sym...

The differential electrostatic space accelerometer is an equivalence principle (EP) experiment instrument proposed to operate onboard China's space station in the 2020s. It is designed to compare the spin-spin interaction between two rotating extended bodies and the Earth to a precision of 10(-12), which is five orders of magnitude better than terrestrial experiment results to date. To achieve ...

A class of efficient mechanisms for allocating a divisible good is studied, which is more general than simple mechanisms discovered independently by Maheswaran and Başar and by us. Strategic buyers play a game by submitting one-dimensional bids, or signals, to the seller. The seller allocates the good in proportion to the bids and charges the buyers nonuniform prices according to the mechanism....

We present a device with integrated buried optical waveguides, a microfluidic channel and photodiodes. This device can, for instance, be used as detection unit for absorption measurements on very small volumes (sub nanoliter) of fluid. The fabricated waveguide and diode structures exhibit a low noise equivalent power of 0.5 nW (488 nm, 10 Hz), demonstrating the possibility of using this setup f...

Photoacoustic microscopy (PAM) does not rely on contrast agent to image the optical absorption contrast in biological tissue. It is uniquely suited for measuring several tissue physiological parameters, such as hemoglobin oxygen saturation, that would otherwise remain challenging. Researchers are designing new clinical diagnostic tools and multimodal microscopic systems around PAM to fully unle...

We have demonstrated Schottky diodes using semiconducting single-walled nanotubes (s-SWNTs) with titanium Schottky and platinum Ohmic contacts for high-frequency applications. The diodes are fabricated using angled evaporation of dissimilar metal contacts over an s-SWNT. The devices demonstrate rectifying behavior with large reverse bias breakdown voltages of greater than -15 V. To decrease the...

A laser scanning optical resolution photoacoustic microscopy (LS OR-PAM) system based on a stationary fibre optic sensor is described. The sensor comprises an optically resonant interferometric polymer cavity formed on the tip of a rounded single mode optical fibre. It provides low noise equivalent pressure (NEP = 68.7 Pa over a 20 MHz measurement bandwidth), a broad bandwidth that extends to 8...

This study investigates the attributes of consumers most likely to be influenced in a number of ways by the information provided by an online environmental infomediary (OEI) GoodGuide.com to advise consumers on the overall and specific sustainability attributes of personal care and household chemical and food products. Consumer attributes are characterized using the value-belief-norm theory and...

We present in this paper optical and X-ray follow up observations for three X-ray selected objects extracted from the ROSAT North Ecliptic Pole survey which is a flux-limited, completely identified survey. All three objects have X-ray luminosities in the 1044 erg s−1 regime and show narrow emission lines in their optical discovery spectra, typical of QSO 2 type objects. Spectroscopic data for t...

1 Abstract: This comprehensive paper argues that Education plays an important role in the process of social change. It is very potential instrument, a powerful medium of bringing about changes in the society. Changes brought about by education are permanent and transcendent in nature. The modern world is changing very fast. This paper suggests that with the help of new communication media, mode...
