OBJECTIVES The objective was to describe the interobserver agreement between trained chart reviewers and physician reviewers in a multicenter retrospective chart review study of children with cervical spine injuries (CSIs). METHODS Medical records of children younger than 16 years old with cervical spine radiography from 17 Pediatric Emergency Care Applied Research Network (PECARN) hospitals ...

As in the paper, suppose that allies use a threshold strategy according to which ally i supports the ruler if her signal ki is below some threshold k , ki ≤ k , and she rebels if ki > k . Since the signal ki is distributed uniformly on the interval [κ t − ε, κ + ε], a threshold signal k implies the existence of a threshold regime strength κ such that a rebellion fails if κ ≤ κ and succeeds if κ...

Assuming 0 does not exist, κ is an uncountable cardinal and for all cardinals λ with κ ≤ λ < κ+ω, 2 = λ+, we present a “mini-coding” between κ and κ+ω. This allows us to prove that any subset of κ+ω can be coded into a subset, W of κ+ which, further, “reshapes” the interval [κ, κ+), i.e., for all κ < δ < κ+, κ = (card δ)L[W∩δ]. We sketch two applications of this result, assuming 0 does not exis...

For any given uncountable cardinal κ with κ = κ, we present a forcing that is <κ-directed closed, has the κ-cc and introduces a lightface definable well-order of H(κ). We use this to define a global iteration that adds such a well-order for all such κ simultaneously and is capable of preserving the existence of many large cardinals in the universe. 2010 Mathematics Subject Classification: 03E47...

On every set A there is a rigid binary relation i.e. such a relation R ⊆ A × A that there is no homomorphism < A,R >→< A,R > except the identity (Vopěnka et al. [1965]). We prove that for each infinite cardinal number κ if card A ≤ 2 then there exists a relation R ⊆ A×A with the following property ∀x ∈ A ∃ {x}⊆A(x)⊆A cardA(x)≤κ ∀ f :A(x)→A f 6=idA(x) f is not a homomorphism of R which implies t...

Assume G.C.H. and κ is the first uncountable cardinal such that there is a non-free κ-free abelian Whitehead group of cardinality κ. We prove that if all κ-free Abelian group of cardinality κ are Whitehead then κ is necessarily an inaccessible cardinal.

We prove, in ZFC alone, some new results on regularity and decomposability of ultrafilters; among them: (a) If m ≥ 1 and the ultrafilter D is (im(λ),im(λ))regular then D is κ-decomposable for some κ with λ ≤ κ ≤ 2 (Theorem 4.3(a)). (b) If λ is a strong limit cardinal and D is (im(λ ),im(λ ))regular then either D is (cf λ, cf λ)-regular or there are arbitrarily large κ < λ for which D is κ-decom...

We aimed to determine whether epidermal growth factor receptor (EGFR) inhibition, in addition to a peroxisome proliferator-activated receptor gamma (PPAR γ ) agonist, prevents high-glucose-induced proximal tubular fibrosis, inflammation, and sodium and water retention in human proximal tubule cells exposed to normal glucose; high glucose; high glucose with the PPAR γ agonist pioglitazone or wit...

We show that a strong form of the so called Lindström’s Theorem [4] fails to generalize to extensions of Lκω and Lκκ: For weakly compact κ there is no strongest extension of Lκω with the (κ, κ)compactness property and the Löwenheim-Skolem theorem down to κ. With an additional set-theoretic assumption, there is no strongest extension of Lκκ with the (κ, κ)-compactness property and the LöwenheimS...
