BACKGROUND To report a case of interface fluid syndrome (IFS) following small incision lenticule extraction (SMILE) evaluated with corneal densitometry and optical coherence tomography (OCT). CASE PRESENTATION An 18-year-old man reported sudden vision loss 24 days after SMILE procedure. Intraocular pressure (IOP) was 36.3 mmHg (OD) and 36.7 mmHg (OS) by noncontact tonometry. Moderate corneal ...

OBJECTIVE To determine the radiographic findings of computed tomographic (CT) imaging most suggestive of invasive fungal sinusitis (IFS) in an immunocompromised patient population. DESIGN A retrospective review of patients with a diagnosis of IFS reached with CT and confirmed by histopathologic evaluation. SETTING An academic tertiary care hospital. PATIENTS Twenty-three immunocompromised...

We investigate the use of iterated function system (IFS) models for data analysis. An IFS is a discrete-time dynamical system in which each time step corresponds to the application of one of the finite collection of maps. The maps, which represent distinct dynamical regimes, may be selected deterministically or stochastically. Given a time series from an IFS, our algorithm detects the sequence ...

In this paper, we present a new feature selection method that is suitable for both unsupervised and supervised problems. We build upon the recently proposed Infinite Feature Selection (IFS) method where feature subsets of all sizes (including infinity) are considered. We extend IFS in two ways. First, we propose a supervised version of it. Second, we propose new ways of forming the feature adja...

We easily tend to think of Integral-Field Spectrographs (IFS) along two opposing trends: as either the beautiful combination between photometry and spectroscopy, or as our worst nightmare including the dark side of both worlds. I favour a view where each IFS is considered individually, as one instrument with specific performances which can be used optimally for a certain range of scientific pro...

One cellular function of intermediate filaments is to provide cells with compliance to small deformations while strengthening them when large stresses are applied. How IFs accomplish this mechanical role is revealed by recent studies of the elastic properties of single IF protein polymers and by viscoelastic characterization of the networks they form. IFs are unique among cytoskeletal filaments...

The technique of image compression using Iterative Function System IFS is known as fractal image compression An extension of IFS theory is called as Partitioned or local Iterative Function System PIFS for coding the gray level images The theory of PIFS appears to be di erent from that of IFS in the sense of application domain Assuming the theory of PIFS is same as that of IFS several techniques...

Standard fractal image compression, proposed by Jacquin[1], is based on IFS (Iterated Function Systems) defined in R. This modelization implies restrictions in the set of images being able to be compressed. These images have to be self similar in R. We propose a new model, the projected IFS, to approximate and code grey level images. This model has the ability to define affine IFS in a high dim...

This paper presents an analysis of the geography of the booming ‘Islamic financial services’ (IFS) sector, which provides a host of financial services based on Islamic religious grounds. The relevance of such an analysis is discussed against the conceptual backdrop of the world city network literature. It is argued that a focus on the globalization of the IFS sector may provide an alternative t...
