BACKGROUND The conventional technique for sacroiliac (SI) joint injection involves aligning the anterior and posterior aspects of the SI joint under fluoroscopic guidance and then entering the SI joint in the most caudal aspect. OBJECTIVE We wish to highlight that there is no added advantage to aligning both the anterior and posterior joint lines of the SI joint as it is time consuming, assoc...

A nanoscale coating of a Si layer on the pore walls of SnO(2) nanotubes (Si-coated SnO(2)) leads to very good electrochemical performance in coulombic efficiency, rate capability and capacity retention compared with untreated SnO(2) nanotubes.

Gold atomic chain structures that grow on singular and vicinal Si(111) surfaces have attracted considerable interest as model systems for exploring quasi–one-dimensional metallic behaviour. The structure of the prototypical Si(111)-5× 2-Au system remains controversial, however. Reflection anisotropy spectroscopy provides new, independent evidence supporting a recently proposed three-Au-chain st...

The adsorption of atomic hydrogen on the reconstructed Si ( lOO)-2 x I surface is studied using embedded Si clusters as models of an extended Si surface. Analytic gradients of generalized valence bond (GVB) wavefunctions are used to predict equilibrium structures and harmonic vibrational frequencies; the correlation-consistent configuration interaction (CCCI) method is used to calculate heats o...

An n-node network, with nodes numbered from – n/2 to n/2 – 1, is a chordal ring network with the chord lengths 1 = s0, s1, . . . , sk–1 (2 ≤ si < n/2) when each node i (– n/2 ≤ i < n/2) is connected to each of the 2k nodes i ± si mod n (0 ≤ i < k) via an undirected link, where “mod” represents symmetric residues. We study a class of chordal ring networks in which the chord length si is ...

A new method is described to prepare strongly bonded, compact monolayer films of alkyl- or arylphosphonates on the native oxide surface of Si (SiO(2)/Si). This method is illustrated for octadecyl- and alpha-quarterthiophene-2-phosphonates. For both cases, AFM shows comprehensive coverage of the SiO(2)/Si surface. The thickness of the continuous film of 4TP/SiO(2)/Si was measured both by AFM and...

Previous studies show that transient increases in both blood flow and magnetic resonance image signal intensity (SI) occur in human muscle after brief, single contractions, and that the SI increases are threefold larger in physically active compared with sedentary subjects. This study examined the relationship between these transient changes by measuring anterior tibial artery flow (Doppler ult...

1 Randomized Strategies or Mixed Strategies Consider a strategic form game: Γ = 〈N, (Si), (ui)〉. The elements of Si are called pure strategies of player i (i = 1, . . . , n). If player i chooses a strategy in Si according to a probability distribution, we have a mixed strategy or a randomized strategy. In the discussion that follows, we assume that Si is a finite for each i = 1, 2, . . . , n. D...
