A simple, yet unifying method is provided for the construction of tilings by tiles obtained from the attractor of an iterated function system (IFS). Many examples appearing in the literature in ad hoc ways, as well as new examples, can be constructed by this method. These tilings can be used to extend a fractal transformation defined on the attractor of a contractive IFS to a fractal transforma...

The IFS/2 is an add-on hardware unit which provides bulk operations on structures such as sets, relations and graphs. This report, which is a sequel to CSM-164, describes seven IFS/2 procedures which perform operations on relations held in the IFS/2’s persistent memory.

BACKGROUND Risk factors and outcomes in hematological patients who acquire invasive fungal sinusitis (IFS) are infrequently reported in the modern medical era. METHOD A retrospective study of hospitalized patients with hematological disease was conducted at National Taiwan University Hospital between January 1995 and December 2009. RESULTS Clinical characteristics and outcomes with their as...

OBJECTIVE To investigate the possible protective effect of recombinant human interleukin-11 (rhIL-11) against ifosfamide (IFS)-induced hemorrhagic cystitis (HC). MATERIALS AND METHODS Male Swiss mice (20-30g) were pretreated with rhIL-11 (25-625 mg, subcutaneously.) 30 min before intraperitoneal injection of IFS (400 mg/kg) or with saline (control group). Twelve hours later, HC was evaluated ...

Keratins K1 and K10 are the most abundant proteins in the upper epidermis where they polymerize to form intermediate filaments (IFs). In addition to their well-established function in providing epidermal stability, K1/K10 (i.e. the dimer between K1 and K10) IFs are supposed to be important for terminal epidermal differentiation and barrier formation. It was previously shown that the imbalanced ...

A modified type of iterated function system (IFS) has recently been shown to generate images qualitatively similar to “classical” chaotic attractors. Here, we use time-delay embedding reconstructions of time-series from this system to generate three-dimentional projections of IFS attractors. These reconstructions may be used to access the topological structure of the periodic orbits embedded wi...

Introduction: Invasive fungal rhinosinusitis is a challenging condition that can be found mostly in immunocompromised patients. Failure to diagnose and treat this entity promptly usually results in rapid progression and death. The purpose of this study was to determine clinical presentation, complication and morbidity in patients with acute versus chronic invasive fungal rhinosinusitis. Setting...

We consider the distribution of the intermediate filaments (IFs) in the retinal cells of the Pied flycatcher (Ficedula hypoleuca, Passeriformes, Aves) in the foveolar zone, which has the most specialized morphology, where the passerines have neither the rods nor the second-order neurons that service these rods, with only the single and double cones acting as photoreceptors. We report that singl...

I applaud the ASM for the decision to put their head above the parapet and cast aside the essentially meaningless metric of journal impact factor (IF). What began as a measure intended to allow quantitative evaluation of the importance of journals, IFs have virtually consumed all other (often more relevant) considerations regarding quality of publication. Ironically, for many of the scientists ...
