Periprosthetic joint infection remains one of the most challenging and pervasive complications following megaprosthetic replacement after tumor resection. The authors conducted a systematic review of the literature for clinical studies that reported a risk factor analysis for perimegaprosthetic joint infections. The search included English-language studies published up to July 2015. Eight studi...

The relationship between inventory investment and the real interest rate has been difficult to assess empirically. Recent work has proposed a linear-quadratic inventory model with time-varying discount factor to identify the effects of real interest rate on inventory investment. The authors show that this framework does not separately identify the effects of real interest rate on inventory inve...

(identical representation). The even part G0 is characterized by the condition a0i = ai0 = 0 for i = 1, . . . , n. G0 is isomorphic to gl(n). We choose the Cartan subalgebra H as the set of diagonal matrices of G and G0 resp. Let eij be denote the (n+ 1)× (n+ 1)-matrix with 1 at the place (i, j) and 0 everywhere (i, j = 0, . . . , n) . Then we get by h1 = e00 + e11 , hi = ei−1,i−1 − eii (i = 2,...

The polarized photoluminescence excitation spectra of twenty-five single-walled carbon nanotube species are reported. For light polarized along the nanotube axis, the main absorption resonance at E22 shows sidebands attributed to phonon assisted absorption. Sidebands to E11 have a diameter dependent energy and are assigned to excited excitonic states. Along with longitudinal excitations, severa...

Reducing uncertainty in 3D carbonate rock type distribution is a critical factor that profoundly impacts field development for hydrocarbon or carbon capture and storage (CCS) projects. Miocene reservoirs the Central Luconia offshore region are economically important global gas reservoirs. The nature of these rocks can be visually distinct core multiscale reservoir heterogeneity might vary scale...

The chick chorioallantoic membrane (CAM) is a widely used model for the study of angiogenesis, tumour growth, as well as drug efficacy. In spite of this, little is known about the developmental alteration from its appearance to the time of hatching. In the current study the CAM has been studied by classical stereology and allometry. Expression levels of selected angiogenesis-related molecules w...

The efficacy of two trap designs (Pherocon 1C "wing" trap versus Pherocon VI "delta" trap) and two pheromone blends for monitoring obliquebanded leafroller, Choristoneura rosaceana (Harris), was evaluated in Minnesota apple orchards during the 2001 and 2002 field seasons. Two distinct flight periods of C. rosaceana were recorded yearly in Minnesota. Overwintered C. rosaceana larvae resumed acti...

We show that the E 11 representation that contains the space-time translation generators also contains the rank two and five totally anti-symmetric representations of A 10. By studying the behaviour of these latter A 10 representations under SL(32), which we argue is contained in the Cartan involution invariant sub-algebra of E 11 , we find that the rank two and five totally anti-symmetric repr...

The transmembrane glycoprotein E11/Podoplanin (Pdpn) has been implicated in the initial stages of osteocyte differentiation. However, its precise function and regulatory mechanisms are still unknown. Due to the known embryonic lethality induced by global Pdpn deletion, we have herein explored the effect of bone-specific Pdpn knockdown on osteocyte form and function in the post-natal mouse. Exte...
