aneurysmal bone cyst (abc) is a benign expansile bone tumor, most commonly involving the medulla of long bones. abc rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary abc changes, and telangiectatic osteosarcoma. both of these are sometimes mistaken micros...

Abstract Background Falls efficacy is a widely-studied latent construct in community-dwelling older adults. Various self-reported instruments have been used to measure falls efficacy. In order be informed of the choice best measurement instrument for specific purpose, empirical evidence development and properties related needed. Methods The Consensus-based Standards Selection Health Measurement...

cABC I (chondroitinase ABC I) from Proteus vulgaris is a GalAG (galactosaminoglycan) depolymerizing lyase that cleaves its substrates at the glycosidic bond via beta-elimination. cABC I cleaves a particularly broad range of GalAG substrates, including CS (chondroitin sulphate), DS (dermatan sulphate) and hyaluronic acid. We recently cloned and recombinantly expressed cABC I in Escherichia coli,...

Conformers of [M(ABC)6] complex have been enumerated on the basis of computational group theory, where M is the central metal, and ABC is the ligand, bound to M through A. Based on the 16 conformers of the M(AB)6 core unit, 7173 conformers have been found for the [M(ABC)6] complex, which are assigned to nine point groups, 1 D3d, 4 D3, 4 S6, 5 C2h, 7 C3, 182 C2, 15 Cs, 23 Ci, and 6932 C1.

ATP-binding cassette transporters are multi-subunit membrane pumps that transport substrates across membranes. While significant in the transport process, transporter architecture exhibits a range of diversity that we are only beginning to recognize. This divergence may provide insight into the mechanisms of substrate transport and homeostasis. Until recently, ABC importers have been classified...

A triple system is partially associative (by deenition) if it satisses the identity (abc)de + a(bcd)e + ab(cde) 0. This paper presents a computational study of the free partially associative triple system on one generator with coeecients in the ring Z of integers. In particular, the Z-module structure of the homogeneous submodules of (odd) degrees 11 is determined, together with explicit genera...

The ABC conjecture of Masser and Oesterlé states that if (a, b, c) are coprime integers with a+ b+ c = 0, then sup(|a|, |b|, |c|) < cǫ(rad(abc)) 1+ǫ for any ǫ > 0. In [2], Oesterlé observes that if the ABC conjecture holds for all (a, b, c) with 16|abc, then the full ABC conjecture holds. We extend that result to show that, for every integer N , the “congruence ABC conjecture” that ABC holds fo...

Approximate Bayesian computation (ABC) is a powerful and elegant framework for performing inference in simulation-based models. However, due to the difficulty in scaling likelihood estimates, ABC remains useful for relatively low-dimensional problems. We introduce Hamiltonian ABC (HABC), a set of likelihood-free algorithms that apply recent advances in scaling Bayesian learning using Hamiltonia...
