Let V be an n-dimensional vector space over the finite field Fq, and [Vk] denote family of all k-dimensional subspaces V. The families F1⊆[Vk1],F2⊆[Vk2],…,Fr⊆[Vkr] are said to r-cross t-intersecting if dim⁡(F1∩F2∩⋯∩Fr)≥t for Fi∈Fi,1≤i≤r. F1, F2,…,Fr non-trivial dim⁡(∩1≤i≤r∩F∈FiF)<t. In this paper, we first determine structure with maximum product their sizes. As a consequence, partially prove o...

We described a method for long-term passive measurements of unattached fraction fp of the potential alpha energy concentration of radon progeny from a set of measured (f1, f2, f3) values, where fi=Ci/C0 (i=1, 2, 3), and C0, C1, C2 and C3 were the concentrations of 222Rn, and the airborne concentrations of 218Po, 214Pb and 214Bi, respectively. Jacobi room model parameters were randomly sampled f...

F2-isoprostanes (F2-IsoPs) are a gold marker of lipid peroxidation in vivo, whereas F4-neuroprostanes (F4-NPs) measured in cerebrospinal fluid (CSF) or brain tissue selectively indicate neuronal oxidative damage. Gas chromatography/negative-ion chemical-ionization mass spectrometry (GC/NICI-MS) is the most sensitive and robust method for quantifying these compounds, which is essential for CSF s...

OBJECTIVE The relations between acoustic measures and their articulatory bases have rarely been tested in dysarthria but are important for diagnostic and treatment purposes. We tested the association between acoustic measures of F2 range and F2 slope with kinematic measures of tongue movement displacement and speed in individuals with amyotrophic lateral sclerosis (ALS) and healthy controls spe...

An adverse environment in early life is often associated with dysregulation of the hypothalamo-pituitary-adrenal (HPA) axis and higher rates of mood disorders in adulthood. In rats, exposure to social stress during pregnancy results in hyperactive HPA axis responses to stress in the adult offspring and heightened anxiety behavior in the males, but not the females. Here we tested whether, withou...

In the presence of F2 overpressure, at elevated temperature, and despite similarity their crystal structures, CuF2 AgF2 unexpectedly form two distinct solid solutions, (Cu1−xAgx)F2 (Ag1−xCux)F2. Each phase shows different mutual solubility Cu2+ Ag2+ (shown as yellow violet balls), magnetic properties are strongly impacted by this seemingly simple isoelectronic substitution. More information can...
