On quasi-Pr\"{u}fer and UM domains
In this note we show that an integral domain of finite -dimension is a
quasi-Pr\"{u}fer domain if and only if each overring of is a -Jaffard
domain. Similar characterizations of quasi-Pr\"{u}fer domains are given by
replacing -Jaffard domain by -stably strong S-domain, and -strong
S-domain. We also give new characterizations of UM domains.Comment: 6 Page
Review of sensors for remote patient monitoring
Remote patient monitoring (RPM) of physiological
measurements can provide an efficient method and high
quality care to patients. The physiological signals
measurement is the initial and the most important factor
in RPM. This paper discusses the characteristics of the
most popular sensors, which are used to obtain vital
clinical signals in prevalent RPM systems.
The sensors discussed in this paper are used to measure
ECG, heart sound, pulse rate, oxygen saturation, blood
pressure and respiration rate, which are treated as the
most important vital data in patient monitoring and
medical examination
Cohen-Macaulay homological dimensions
We introduce new homological dimensions, namely the Cohen-Macaulay
projective, injective and flat dimensions for homologically bounded complexes.
Among other things we show that (a) these invariants characterize the
Cohen-Macaulay property for local rings, (b) Cohen-Macaulay flat dimension fits
between the Gorenstein flat dimension and the large restricted flat dimension,
and (c) Cohen-Macaulay injective dimension fits between the Gorenstein
injective dimension and the Chouinard invariant.Comment: To appear in Mathematica Scandinavic
