Recent reports have identified committed innate lymphoid cell (ILC) precursors and tissue-resident ILC subsets that have unique functional attributes. Taken together, these studies provide a framework for understanding how distinct ILCs are generated during hematopoiesis and further suggest additional parallels between models of ILC and T helper cell differentiation.

BACKGROUND We examined the efficiency and cost effectiveness of a temperature feedback diode-laser system in the treatment of benign prostatic hypertrophy (BPH). METHODS One hundred twenty patients with symptomatic BPH were included in this study between October 1997 and January 1998. Sixty of them were treated by transurethral resection of the prostate (TUR-P), and 60 patients were treated b...

BACKGROUND Innate lymphoid cells (ILC) are a new family of innate immune cells that have emerged as important regulators of tissue homeostasis and inflammation. However, limited data are available concerning the relative abundance and characteristics of ILC in the human lung. METHODS The aim of this study was to characterize and enumerate the different ILC subsets in human lung by multi-color...

Invasive lobular carcinoma (ILC) is a histologic subtype of breast cancer that is frequently associated with favorable outcomes, as approximately 90% of ILC express the estrogen receptor (ER). However, recent retrospective analyses suggest that patients with ILC receiving adjuvant endocrine therapy may not benefit as much as patients with invasive ductal carcinoma. On the basis of these observa...

The two-dimensional (2-D) system theory iterative learning control (ILC) techniques for linear time-invariant discrete systems are extended to the cases of linear time-variant discrete systems. By exploiting the convergent property of 2-D linear time-variant discrete systems with only one independent variable, a kind of 2-D system theory ILC approach is presented for linear time-variant discret...

A sinister and stealthy marauder, infiltrating lobular carcinoma (ILC) can potentially elude detection due to its pathologic appearance. As reviewed in the last issue of The WCC Note, the shape of ILC at pathology varies. It ranges from tumors with irregular margins; to those displaying diffuse invasion with cells infiltrating single file or loosely associated; to variants with large groups of ...

We derive frequency-domain criteria for the convergence of linear iterative learning control (ILC) on finite-time intervals that are less restrictive than existing ones in the literature. In particular, the former can be used to establish the convergence of ILC in certain cases where the latter are violated. The results cover ILC with non-causal filters and provide insights into the transient b...

This paper presents a stability analysis of the iterative learning control (ILC) problem when the plant Markov parameters are subject to interval uncertainty. Using the super-vector approach to ILC, vertex Markov matrices are employed to develop sufficient conditions for both asymptotic stability and monotonic convergence of the ILC process. It is shown that Kharitonov segments between vertex m...

Many schemes of iterative learning control (ILC) have been developed for continuous-time, non-linear dynamic systems to improve tracking performance. Two schemes, D-type and P-type, have been the bases for many ILC designs. Recently, the anticipatory ILC scheme has been introduced, on the basis of a di€ erent approach (Wang 1998a, 1999). In this paper, these basic schemes are compared from both...
