conclusions current study revealed that a. flavus was the most common isolated pathogen. moreover, a. fumigatus was the second common isolated pathogen in patients with ifs. additionally, the hospital construction was an important environmental risk factor for acquisition of infection in patients with hematological malignancy. the most common season for ifs incidence was summer. additionally, t...
A representation of atmospheric chemistry has been included in the Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF). The new chemistry modules complement the aerosol modules of the IFS for atmospheric composition, which is named C-IFS. C-IFS for chemistry supersedes a coupled system in which chemical transport model (CTM) Model for OZone and ...
OBJECTIVE • To evaluate a novel technique to lower positive surgical margin rates while preserving as much of the neurovascular bundles as possible during nerve-sparing robotic prostatectomy. MATERIALS AND METHODS • In situ intraoperative frozen section (IFS) was performed during robotic-assisted laparoscopic prostatectomy (RALP) when there was macroscopic concern for a positive margin or resid...
Invasive fungal sinusitis (IFS) is a highly aggressive infection that can affect hematologic patients. The classically described general risk factors, however, do not fully explain the development of IFS in a small percentage of cases. This study examined the impact of anatomic sinonasal factors and environmental factors on the development of IFS in high-risk patients. Medical records and compu...
This paper presents a hybrid system to speed up image fractal encoding. The coding scheme, LP–IFS, consists of linear prediction (LP) and Iterated Functions Systems (IFS) applied in cascade on the image. The LP process employs a 2D auto-regressive model to estimate parameters for each block in the image partition; IFS are then used instead of adaptive quantizers to encode linear prediction erro...
Intermittent faults (IFs) are difficult to diagnose and may cause a great disruption in industrial processes. Most IFs are related to gradual degradation of components or systems. For instance, evolution of connection failures is shown in Fig. 1 (Correcher et al., 2004), (Sorensen et al, 1998). Connection failures are rarely repaired so its behaviour worsens over time. Intermittent faults behav...
No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to st...
Following their early success in the utilisation of IFS to describe fractals, Barnsley and Demko mounted an investigation of the applicability of the IFS scheme for the description of arbitrary shapes. Central to the (general) IFS has became what they refer to as the collage theorem: the notion that if a figure can be "lazy tiled" with sufficient accuracy by smaller copies of itself at various ...
