Standards for gas service

The method of analyzing the results of cosmic ray deflection experiments, developed in a previous paper, is here extended to the case where the region of uniform deflecting field is of the same width as that of the counters. In this form it is applicable to the electrostatic deflection experiment of Lenz, and to the electrostatic and magnetic experiments of W. F. G. Swann and the writer. The magnetic experiments of Curtiss and of Mott-Smith are reexamined in the light of the energy distribution recently published by Anderson and Nedderineyer. The latter's result is found to be not inconsistent with the assumption that the induction B gives the correct force; the result of the former requires the addition of low energy rays to the distribution.

A computer-oriented approach to obtaining an analytical expression of an impulse response of a one- or two-dimensional filter

A method is presented, that can be readily written in a computer program, to obtain the closed-form solution of the impulse response of a digital filter. The extension of this approach to two-dimensional digital filters and to analog filter transfer functions is also presented. Examples are shown.     

Paper-based analytical devices for point-of-care blood tests

Blood can be a window to health, and as a result, is the most intensively studied human biofluid. Blood tests can diagnose diseases, monitor therapeutic drugs, and provide information about the health of an individual. Rapid response blood tests are becoming increasingly essential, especially when subsequent treatment is required. Toward this need, paper-based devices have been excellent tools for performing blood tests due to their ability to conduct rapid and low-cost diagnostics and analyses in a non-laboratory environment. In this Perspective, we review recent advances in paper-based blood tests, particularly focusing on the specific techniques and assays applied. Additionally, we discuss the future of these paper-based devices, such as how the signal intensity can be enhanced and how the in situ synthesis of nanomaterials can be used to improve the sensitivity, functionality, and operational simplicity. With these advances, paper-based devices are becoming increasingly valuable tools for point-of-care blood tests in various practical scenarios.
