Location Fingerprinting (LF) is a promising location technique for many awareness applications in pervasive computing. However, as research on LF systems goes beyond basic methods there is an increasing need for better comparison of proposed LF systems. Developers of LF systems are also lacking good frameworks for understanding different options when building LF systems. This paper proposes a t...

Recently there has been a rapidly growing interest in RFID systems and its applications. Operating frequencies including 125 KHz–134 KHz and 140 KHz–148.5 KHz LF band, 13.56 MHz HF band and 868 MHz–960 MHz UHF band were applied to various supply chains. 433 MHz band was decided for active reader and 2.45 GHz band was applied for WiFi reader. Besides the reader antennas, the requirements of tag ...

This study evaluated the influence of cooking methods (blanching, pan-frying, and microwaving) on the antioxidant activity of Ligularia fischeri (LF) using myoglobin methods against five different reactive oxygen species (ROS) (i.e., 2,2-diphenyl-1-picrylhydrazyl (DPPH), hypochlorite ions, hydroxyl radicals, peroxyl radicals, and peroxynitrite ions). With respect to DPPH scavenging activity, th...

BACKGROUND Ligamentum flavum (LF) hypertrophy is a common cause of lumbar spinal stenosis and is thought to be degeneration-driven. Developmental spinal stenosis (DSS) is characterized by pre-existing narrowed spinal canals and is likely a developmental problem that occurs in childhood. In these cases, the LF may demonstrate different characteristics as compared to degeneration-driven stenosis....

and Applied Analysis 3 then lim k Uf Lf, ∀f ∈ C X . 3.2 Moreover, if X is a compact metric space, then the convergence is uniform. Proof. Let f ∈ C X . The case when Lf f is trivial. Indeed, in this case, since Lf ∈ V andU preserves the elements of V, we haveUf ULf Lf , and hence Uf Lf , k 1, 2, . . . . If Lf / f , for sufficiently small ε > 0, the inverse image of the open set −ε, ε under the ...

Lactoferrin receptor (LfR) is expressed in most mammalian tissues including placental trophoblasts and is presumed to mediate the internalization of lactoferrin (Lf). However, the physiological significance of trophoblast LfR is not understood. Using a cytotrophoblast cell model (BeWo) we demonstrated that transfection with LfR siRNA significantly decreased apo- but not holo-Lf uptake compared ...
