Measurement of arterial input function (AIF) for quantitative positron emission tomography (PET) studies is technically challenging. The present study aimed to develop a method based on a standard arterial input function (SIF) to estimate input function without blood sampling. We performed (18)F-fluolodeoxyglucose studies accompanied by continuous blood sampling for measurement of AIF in 11 rat...

North America's first government sanctioned medically supervised injection facility (SIF) was opened during September 2003 in Vancouver, Canada. This was in response to a large open public drug scene, high rates of HIV and hepatitis C transmission, fatal drug overdoses, and poor health outcomes among the city's injection drug users. Between December 2003 and April 2005, a representative sample ...

To tackle the difficulty in obtaining response data of chain and bulk coal under faults, this paper uses a new method for fault simulation scraper chains based on coupling multi-body dynamics (MBD), discrete element (DEM), finite (FEM). With force stacking angle as values, contact parameters were revised using rotary transport test. The simplified DEM-MBD model was verified from resistance poin...

Remote sensing of solar-induced chlorophyll fluorescence (SIF) shows promise for monitoring the productivity global agricultural systems. SIF-based primary metrics have demonstrated higher fidelity to large-scale patterns crop than reflectance-based vegetation indices when averaged across growing season. In-season yield forecasting typically relies upon indices, raising question whether in-seas...

Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...

In this paper, an adaptive formulation of the sliding innovation filter (SIF) is presented. The SIF a recently proposed estimation strategy that has demonstrated robustness to modeling errors and uncertainties. It utilizes switching gain function (measurement error) boundary layer term. time-varying derived based on minimizing state error covariance. resulting solution creates SIF. applied line...

The collection of various long-term reconstructed solar-induced fluorescence (SIF) datasets derived at a range spatio-temporal scales provides new opportunities for modelling vegetation dynamics, in particular, gross primary productivity (GPP). Information about the proximity SIF (SIFr) to GPP across land cover types and climatic conditions important support better application these products ap...

Earlier in our laboratory, sperm immobilization factor (SIF) isolated from Escherichia coli has shown admirable contraceptive efficacy female mice and thus generated interest evaluating the same as a potential candidate for male contraception. Keeping this mind, present study was aimed at exploitation of SIF agent mouse model after intra testis administration. For this, Balb/c were administered...

Sacral insufficiency fracture is a known complication after pelvic radiotherapy. The condition can be missed if clinical suspicion is not high er can be misdiagnosed as metastases. Imaging modalities play a vital role in correct diagnosis of this pathology. We describe intriguing ‘Butterfly sign’/’Honda sign’ in sacro-iliac region on bone scan in a patient of carcinoma cervix. Further clinical ...

This paper examines the design of social investment funds (SIFs) and explores the ways they affect agents’ incentives to propose, select, and implement good projects. Compared with other forms of decentralized service provision, SIFs possess features of administratively delegated authority and deep political devolution. Where existing political institutions fail to deliver assistance to vulnera...
