Strength-Probability-Time (SPT) diagrams provide an intuitively pleasing method for presenting reliability data based on extrapolations from accelerated fatigue testing data. If power-law crack growth kinetics are assumed the calculations required to generate the SPT diagram are particularly simple. However, if exponential or other more complex forms are used, this is not the case. If the accel...

Case report A 62 year old male was assessed in 2006 with a 3-4 year history of recurrent acute urticaria. A month prior to consultation he developed anaphylaxis. No consistent trigger was identified, therefore a covariable with food, such as exercise, was suspected. Skin prick testing (SPT) to foods ingested within 4 hours of anaphylaxis was positive to wheat flour and negative to wheat extract...

Current literature remains controversial regarding whether to treat patients sustaining pelvic fracture urethral injuries (PFUIs) with primary endoscopic realignment (PER) versus suprapubic tube (SPT) placement alone with elective bulbomembranous anastomotic urethroplasty (BMAU). Success rates for PER following PFUI are wide-ranging, depending on various authors' definitions of what defines a s...

Introduction: Skin prick testing (SPT) is a common test to diagnose IgE sensitization and the rate of adverse reactions is very low. Case Presentation: 29-year-old woman with anaphylactic reaction to routine SPT with 11 allergens (aero and food). Discussion: Allergy profile included multiple food and inhalant allergies, polysensitization, prior episode of anaphylaxis to mushrooms, active eczema...

Atomistic mechanisms of fracture accompanying structural phase transformation (SPT) in AlN ceramic under hypervelocity impact are investigated using a 209 x 10(6) atom molecular-dynamics simulation. The shock wave generated by the impact splits into an elastic wave and a slower SPT wave that transforms the wurtzite structure into the rocksalt phase. The interaction between the reflected elastic...

Thermal buckling response of functionally graded plates is presented in this paper using sinusoidal shear deformation plate theory (SPT). The material properties of the plate are assumed to vary according to a power law form in the thickness direction. Equilibrium and stability equations are derived based on the SPT. The non-linear governing equations are solved for plates subjected to simply s...

Shortest-path tractography (SPT) algorithms solve global optimization problems defined from local distance functions. As diffusion MRI data is inherently noisy, so are the voxelwise tensors from which local distances are derived. We extend Riemannian SPT by modeling the stochasticity of the diffusion tensor as a “random Riemannian metric”, where a geodesic is a distribution over tracts. We appr...

|ξ| ≤ f(x, u, ξ) ≤ L(1 + |ξ|). A function u ∈ W 1,p loc (Ω) is a local minimizer of F in Ω if F (u; spt (v − u)) ≤ F (v; spt (v − u)) , for every v ∈ W 1,p loc (Ω) such that spt (v − u) ⊂⊂ Ω. Well known results due to Giaquinta and Giusti [13, 15] ensure that local minimizers of F are locally α-Hölder continuous for some α < 1. According to Meyers’ example in [19], when f is not continuous in Ω...

Subdiffusion and its causes in both in vivo and in vitro lipid membranes have become the focus of recent research. We report apparent subdiffusion, observed via single particle tracking (SPT), in a homogeneous system that only allows normal diffusion (a DMPC monolayer in the fluid state). The apparent subdiffusion arises from slight errors in finding the actual particle position due to noise in...
