Most ecological management applications use wireless sensor networks (WSNs) to collect data regularly, with great temporal redundancy. As a result, significant amount of energy is used transmitting redundant data, making it tremendously problematic attain satisfactory network lifetime, which bottleneck in enduring such environmental monitoring applications. A two-vector prediction model that ba...

We investigated microscopic lattice states in the donor-acceptor ionic Mott insulator, tetrathiafulvalene-bromanil (TTF-BA), by $^{79}\mathrm{Br}\text{\ensuremath{-}}$nuclear quadrupole resonance (NQR) spectroscopy to explore cross-correlated fluctuations between spin, charge, and lattice. A ferroelectric transition with dimerization is captured a NQR line splitting critical exponent $\ensurema...

Ž . The dc Superconducting QUantum Interference Device SQUID is a sensitive detector of magnetic flux, with a typical flux noise of the order 1 mF Hz at liquid helium temperatures. Here F s"r2 e is the flux quantum. In our NMR or 0 0 NQR spectrometer, a niobium wire coil wrapped around the sample is coupled to a thin film superconducting coil deposited on the SQUID to form a flux transformer. W...

We performed 121/123Sb-nuclear quadrupole resonance (NQR) measurements on the superconducting (SC) line-nodal material CaSb2 in order to investigate electronic properties normal and SC states from a microscopic point of view. In state, nuclear spin-lattice relaxation rate 1/T1 for Sb(1) site, which is responsible parts, approximately proportional temperature, indicating conventional Fermi liqui...

Introduction Mentorship/Preceptorship (M/P) has been utilised within the nursing profession since early 1980's. Successful, structured M/P programmes can be hugely beneficial to Northern Ireland (NI) Trusts who recruit regularly and often rely on fluidity of staff movement regionally. In absence standardised tools accurately universally measure competency newly qualified Radiographers (NQR) as ...

The temperature dependence of the 81 Br NQR frequencies of the title compound has revealed the presence of three phases (I, II and III, in the order of decreasing temperature): Tcl (II -1) = (318 ± 10) K and Tc2 (III II) = (202 ± 1) K. The transitions were confirmed by thermal analysis (DTA). Both of the II-I and I-II transitions exhibited strong hysteresis (/. e., superheating and supercooling...

The C1 NQR spectra of the two phases (phases I and II) of 2,3-dichloro-l,4-naphthoquinone were studied from 77 to 394 K. The crystal structure determination of the triclinic phase (phase I) was refined by single crystal X-ray diffraction. Phase I crystallizes in the space group C/-P1. The unit cell (Z = 4) has the dimensions a = 1614.3(4) pm, 6 = 828.1 (3) pm, c = 733.2(3) pm, a = 67.02(l)°, /?...

Cocrystals of 4,4'-bipyridyl and several carboxylic acids were grown from the methanol solution of the cocrystal formers. Complete (14)N NQR spectra of these cocrystals have been measured using (1)H-(14)N nuclear quadrupole double resonance. The principal values of the quadrupole coupling tensor are calculated from the (14)N NQR frequencies. A large variation in the (14)N quadrupole coupling co...

BACKGROUND With a pending need to identify potential means to improved quality of care, national quality registries (NQRs) are identified as a promising route. Yet, there is limited evidence with regards to what hinders and facilitates the NQR innovation, what signifies the contexts in which NQRs are applied and drive quality improvement. Supposedly, barriers and facilitators to NQR-driven qual...
