It took more than 100 years before it was established that the proteins that form intermediate filaments (IFs) comprise a unified protein family, the members of which are ubiquitous in virtually all differentiated cells and present both in the cytoplasm and in the nucleus. However, during the past 2 decades, knowledge regarding the functions of these structures has been expanding rapidly. Many ...

FOLPI is a Linear Programming-based planning system that can be used by forest managers without a detailed knowledge of Linear Programming (LP). It is compatible with IFS, an interactive forest simulator widely used by the New Zealand Forest Service. The system allows the user to state the problem in forestry terms, within a framework similar to that used by IFS. The problem statement is automa...

Abstract: A hyperbolic iterated function system (IFS) whose attractor is the graph of a continuous function f : [a, b] × [c, d] → R that interpolates the given data in R is considered. The function f is called the bivariate fractal interpolation function (FIF) arising from the IFS and the graph of f which is a surface in R is called the bivariate fractal interpolation surface (FIS). By introduc...

We report here the genetic findings of a new isolated familial somatotropinoma (IFS) kindred in which the mother (subject I:2) and one daughter (subject II:2) are affected; their ages at diagnosis were 25 and 14 years respectively. Additionally, patient I:2 developed virilization due to an androgen-secreting adrenocortical mass, presenting clinical and molecular features of sporadic adrenal car...

In view of their perceived chemopreventive activities against hormone-dependent cancers, cardiovascular disease, and postmenopausal ailments, there is considerable interest in engineering plants to contain isoflavone phytoestrogens. However, attempts to date have only resulted in low levels of isoflavone accumulation in non-legumes. Introducing soybean isoflavone synthase (IFS) into Arabidopsis...

The information age brings some unique challenges to society. New technology and new applications bring new threats and force us to invent new protection mechanisms. So every few years, computer security needs to reinvent itself. In this paper we propose a new image encoding system utilizing fractal theories; this approach exploits the main feature of fractals generated by IFS techniques. Two l...

We refer to such strings as Instant Folded Strings (IFS). study exact worldsheet CFT description of IFS involves two vertex operators which describe open modes propagate on time-like FZZT-brane, plays the role regulator IFS. take advantage this calculate most b...

PURPOSES It has been reported that the amount of posterior tilt and upward rotation in scapular motions decreases with aging. The purposes of the current study were to investigate age related scapular motion regression and scapular restriction in patients with idiopathic frozen shoulder (IFS). METHODS The groups were recruited as follows: two groups of 50 asymptomatic subjects aged in their t...

MRI is used routinely in research with children to generate new knowledge about brain development. The detection of unexpected brain abnormalities (incidental findings; IFs) in these studies presents unique challenges. While key issues surrounding incidence and significance, duty of care, and burden of disclosure have been addressed substantially for adults, less empirical data and normative an...
