The joint use of multi-frequency signals brings new prospects for precise positioning and has become a trend in Global Navigation Satellite System (GNSS) development. However, a new type of inter-frequency clock bias (IFCB), namely the difference between satellite clocks computed with different ionospheric-free carrier phase combinations, was noticed. Consequently, the B1/B3 precise point posit...

Aflatoxin B1 and benzo(a)pyrene were activated by both cultured human bronchus and human colon as measured by binding to cellular DNA and protein. The binding of aflatoxin B1 to DNA was dose dependent, and the level of binding was higher in cultured human bronchus than it was in the colon. When compared to aflatoxin B1, the binding level of benzo(a)pyrene to both bronchial and colonic DNA was g...

(-)-Ceralure B1 (ethyl-cis-5-iodo-trans-2-methylcyclohexane-1-carboxylate), a male attractant for the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is significantly more attractive than trimedlure (tert-butyl esters of 4(5)-chloro-2-methylcyclohexane-1-carboxylate), the current standard male attractant used in detection programs. This article reports studies that compare the effectiv...

Introduction In high field MRI, the increased interactions between the electromagnetic waves and the biological tissues may give rise to heat and thermal hazards. This is clearly apparent for multi-transmit array applications where the electromagnetic fields are heavily manipulated in the subject to be imaged. In this work we provide complete 3D predictions of the B1 + fields, MRI images, energ...

Let X be an n–element finite set, 0 < k < n/2 an integer. Suppose that {A1, B1} and {A2, B2} are pairs of disjoint k-element subsets of X (that is, |A1| = |B1| = |A2| = |B2| = k,A1 ∩ B1 = ∅, A2 ∩ B2 = ∅). Define the distance of these pairs by d({A1, B1}, {A2, B2}) = min{|A1−A2|+ |B1−B2|, |A1−B2|+ |B1−A2|}. It is known ([2]) that this is really a distance on the space of such pairs and that the ...

Introduction: B1 mapping is important in a variety of new MR applications, including the design of RF pulses in parallel transmit systems and flip angle calibration for T1 mapping. The Bloch-Siegert (BS) B1 mapping method has been recently introduced as a fast, accurate and robust technique for B1 mapping [1]. In order to compare the quality of B1 maps acquired with the BS method to other metho...

Five monoclonal antibodies were obtained after fusion of mouse P3 x 63 myeloma cells with spleen cells isolated from BALB/c mice that had been immunized with aflatoxin B1-adducted DNA complexes with methylated bovine serum albumin. Selected hybridomas were found to produce monoclonal antibodies specific for modified DNA containing both the 2,3-dihydro-2-(N7-guanyl)-3-hydroxyaflatoxin B1 and the...

GARP/LRRC32 was defined as a marker of activated human regulatory T cells (Tregs) that is responsible for surface localization of latent TGF-b1. We find that GARP and latent TGF-b1 are also found on mouse Tregs activated via TCR stimulation; however, in contrast to human Tregs, GARP is also expressed at a low level on resting Tregs. The expression of GARP can be upregulated on mouse Tregs by IL...
