Shrinkage Fissures

Anal fissures; first do no harm.

emergency centre staffed with GPs, nurse practitioners, and emergency medicine doctors. Handover between OOH and in-hours GPs has been defined as ‘one of the most perilous procedures in medicine, and when carried out improperly can be a major contributory factor to subsequent error and harm to patients’.1 In-hours care accounts for 50 hours/week while OOH care accounts for 118 hours/week. Hando...

Radiologic evaluation of spinal cord fissures.

The clinical course and radiographic studies were reviewed of eight patients with posttraumatic spinal cord fissures (rents in the spinal cord communicating with the subarachnoid space). Five patients had spinal cord fissures associated with symptomatic intramedullary cysts that required shunting to alleviate progressive neurologic deficits and intractable pain. Their metrizamide myelograms sho...

Shrinkage regression

Bayesian shrinkage

Penalized regression methods, such as L1 regularization, are routinely used in high-dimensional applications, and there is a rich literature on optimality properties under sparsity assumptions. In the Bayesian paradigm, sparsity is routinely induced through two-component mixture priors having a probability mass at zero, but such priors encounter daunting computational problems in high dimension...

Predicting the distribution of ground fissures and water-conducted fissures induced by coal mining: a case study

INTRODUCTION The use of Top Coal Caving for exploiting the thick coal seam with shallow buried depth most likely has a strong negative impact on the stability. CASE DESCRIPTION Anjialing No. 1 Underground Mine is located in Shuozhou City, Shanxi Province of China. The 4# Coal Seam of this coal mine is the thick coal seam with shallow buried depth, which has the thickness of 12 m and the depth...
