BACKGROUND Although it is widely recognised that frail older persons need adaptation of healthcare services, it is unclear how hospital care in general can best be tailored to their frailty. OBJECTIVE To systematically review the evidence for hospital-wide interventions for older patients. METHODS PubMed, Cochrane CENTRAL, Cinahl and reference lists of included articles (1980-2009) were sea...

Dual-frequency GPS TEC monitors have been used to study the response of the ionosphere to the solar eclipses of 22 July 2009 and 15 January 2010. The receivers were located at three stations, Calcutta, Kharagpur and Baharampore which are situated outside the umbra zone in the Indian longitude sector with each baseline being ∼200 km. Effects of obscuration of the solar disc were noted in the amb...

Myeloablative conditioning results in thymic epithelial cell (TEC) injury, slow T-cell reconstitution, and a high risk of opportunistic infections. Keratinocyte growth factor (KGF) stimulates TEC proliferation and, when given pre-conditioning, reduces TEC injury. Thymocytes and TEC express androgen receptors and exposure to androgen inhibits thymopoiesis. In this study, we have investigated whe...

Deterministic nonlinear prediction is a pow erful tec hnique for the analysis and prediction of time series generated by nonlinear dynamical systems. In this paper the use of a Kohonen netw ork asa component of one deterministic nonlinear prediction algorithm is suggested. In order to evaluate the performance of the proposed algorithm, it was applied to the prediction of time series generated b...

in this paper, we propose a new residual analysis method using fourier series transform into fuzzy time series model for improving the forecasting performance. this hybrid model takes advantage of the high predictable power of fuzzy time series model and fourier series transform to fit the estimated residuals into frequency spectra, select the low-frequency terms, filter out high-frequency term...

In this study, we present a Rate of Total Electron Content Index (ROTI)-aided equatorial plasma bubbles (EPBs) detection method based on Global Navigation Satellite System (GNSS) ionospheric (TEC). This technique seeks the EPBs occurrence time according to ROTI values and then extracts detrended TEC series, which include signals using low-order, partial polynomial fitting strategy. The over Hon...

Acoustic-Gravity Waves in the neutral atmosphere induce disturbances distribution of electrons ionosphere that can be observed Total Electron Content (TEC) Global Navigation Satellite System (GNSS) signals. Large GNSS networks such as Japan's GEONET provide spatially dense samples TEC time series which crosscorrelated to detect coherent structure these disturbances. Identifying atmospheric wave...

Using the data of 382 ground global navigation satellite system (GNSS) network stations in Western China, we studied and analyzed ionospheric disturbances triggered by “Long March” 2D rocket launch Jiuquan, China on December 3, 2017. As compared with previous research, a higher sampling resolution for GNSS (with frequency 1 Hz) was used to obtain more accurate occurrence times propagation veloc...

Usually, ionospheric Total Electron Content (TEC) variation with time can be viewed as a stationary random process under quiet conditions. However, sudden events of the Sun and the Earth such as solar flare and sudden commencement of geomagnetic storms may induce the disturbances of the ionosphere, so that the stationary random process is broken; the statistical model parameters change much. Ba...

IFN-γ-/-NOD.H-2h4 mice develop thyroid epithelial cell hyperplasia (TEC H/P) characterised by abnormal proliferation of thyrocytes and infiltration of thyroids by CD4+ and CD8+ T cells, macrophages and dendritic cells. CD8+ T cells from mice with severe TEC H/P transfer similar lesions to SCID recipients, whereas CD4+ T cells transfer mild TEC H/P. CD4- and CD8- deficient IFN-γ-/-NOD.H-2h4 mice...
