We report the development of a CdZnTe gamma ray imager whose advantages over the conventional Anger camera include 1) improved contrast resulting from superior energy resolution and unambiguous position determination and 2) the small size and weight and high reliability inherent in an all-solid-state construction. It provides high energy resolution and peak efficiency by incorporating Digirad's new SpectrumPlusTM detector technology. The new imager employs a modular design, in which each 1" x 1" module incorporates a monolithic 64-element CdZnTe detector array and ASIC-based circuity that provides signal conditioning for every channel, identification of valid events and addressing fimctions. Imagers with a wide range of sizes and shapes can be assembled by tiling modules together on a specially designed signal routing board.
The UK National Health Service (NHS) is faced with problems of managing patient discharge and preventing the problems that result from it such as frequent readmissions, delayed discharge, long waiting lists, bed blocking and other such consequences. The problem is exacerbated by the growth in size, complexity and the number of chronic diseases in the NHS. In addition, there is an increase in demand for high quality care, processes and planning. Effective Discharge Planning (DP) requires practitioners to have appropriate, patient personalised and updated knowledge in order to be able to make informed and holistic decisions about a patients’ discharge. This paper examines the role of Knowledge Management (KM) in both sharing knowledge and using tacit knowledge to create appropriate patient discharge pathways. The paper details the factors resulting in inadequate DP, and demonstrates the use of Internet of Things (IoT) and Machine2Machine (M2M) as candidate technologies and possible solutions which can help reduce the problem. The use of devices that a patient can take home and devices which are perused in the hospital generate information, which can serve useful when presented to the right person at the right time, thus harvesting knowledge. The knowledge when fed back can support practitioners in making holistic decisions with regards to a patients’ discharge.

Poisson's equation and the trap dynamics were used to calculate the time-dependent behavior of electrons, holes, and traps in the oxide during and after irradiation for various typical conditions. These results were used to calculate flatband shift versus gate bias voltage for steady-state as well as non-steady-state conditions. These exact computations confirm a previously published approximate two-layer model for irradiated MOS capacitors. PACS numbers: 61.80.Fe, 73.40.Qv, 85.30.Tv FIG. I.
