The Evolution of Interstate Security Crisis-ManagementTheory and Practice in China

As the frequency and scope of China’s paramilitary and military presence activities in the East and South China Seas have increased in the last few years, officials and analysts inside and outside China have worried more and more about the potential for military crises erupting between China and other actors. Given the perceived high stakes of many of these potential disputes—they touch on sovereignty, territorial integrity, national dignity, and development resources—some observers are concerned about the risks of escalation to military conflict, whether deliberate or accidental.1 Adding to the worries is uncertainty about China’s commitment to crisis management and escalation control.

A random forest model for predicting the crystallisability of organic molecules

A random forest model has for the first time enabled the prediction of the crystallisability (crystals vs. no crystals) of organic molecules with ∼70% accuracy. The predictive model is based on calculated molecular descriptors and published experimental crystallisation propensities of a library of substituted acylanilides

A predicted dimer-based polymorph of 10,11-dihydrocarbamazepine (Form IV)

A novel polymorph of 10,11-dihydrocarbamazepine (form IV), which had been predicted to be thermodynamically feasible, was obtained from the vapour phase and displays an R22(8) hydrogen bonded dimer motif in contrast to the catemeric motifs in forms I–III

Carbamazepine on a carbamazepine monolayer forms unique 1D supramolecular assemblies

High-resolution STM imaging of the structures formed by carbamazepine molecules adsorbed onto a pseudo-ordered carbamazepine monolayer on Au(111) shows the formation of previously unreported 1-dimensional supramolecular assemblies

The Knee Arthroplasty Trial (KAT) : design features, baseline characteristics and two-year functional outcomes after alternative approaches to knee replacement

Background: The aim of continued development of total knee replacement systems has been the further improvement of the quality of life and increasing the duration of prosthetic survival. Our goal was to evaluate the effects of several design features, including metal backing of the tibial component, patellar resurfacing, and a mobile bearing between the tibial and femoral components, on the function and survival of the implant. Methods: A pragmatic, multicenter, randomized, controlled trial involving 116 surgeons in thirty-four centers in the United Kingdom was performed; 2352 participants were randomly allocated to be treated with or without a metal backing of the tibial component (409), with or without patellar resurfacing (1715), and/or with or without a mobile bearing (539). Randomization to more than one comparison was allowed. The primary outcome measures were the Oxford Knee Score (OKS), Short Form-12, EuroQol-5D, and the need for additional surgery. The results up to two years postoperatively are reported. Results: Functional status and quality-of-life scores were low at baseline but improved markedly across all trial groups following knee replacement (mean overall OKS, 17.98 points at baseline and 34.82 points at two years). Most of the change was observed at three months after the surgery. Six percent of the patients had additional knee surgery within two years. There was no evidence of differences in clinical, functional, or quality-of-life measures between the randomized groups at two years. Conclusions: Patients have substantial improvement following total knee replacement. This is the first adequately powered randomized controlled trial, of which we are aware, in which the effects of metal backing, patellar resurfacing, and a mobile bearing were investigated. We found no evidence of an effect of these variants on the rate of early complications or on functional recovery up to two years after total knee replacement. Level of Evidence: Therapeutic Level I.

John Feron And His 'Address' On A Veterinary Institution In Edinburgh

The earliest pieces of evidence for the first formal teaching of farriery and veterinary medicine in the town are to be found in newspaper advertisements for a series of lectures to be held in Bernard's Rooms, Thistlestreet, Edinburgh from the 19th to the 22nd July 1796. The lecturer was a French Royalist refugee, John Feron who presented himself as a 'Professor of Veterinary Medicine'
