Development of durable non-wetting surfaces is hindered by the fragility of the microscopic roughness features that are necessary for superhydrophobicity. Mechanical wear on superhydrophobic surfaces usually shows as increased sticking of water, leading to loss of non-wettability. Increased wear resistance has been demonstrated by exploiting hierarchical roughness where nanoscale roughness is p...

Is the variety of products supplied in markets a reflection of the diversity of consumers’ preferences? In this paper, we argue that the distribution of durable goods offered in markets tends to be compressed relative to the distribution of consumers’ underlying preferences. In particular, there are strong incentives for conformity in markets for durable goods. The reason for conformity is natu...

The process of performing a Side Channel Attack is generally a computationally intensive task. By employing a number of simple optimisations the data analysis phase of the attack can be greatly improved. In this paper we will describe some of these improvements and show in the context of DES when attacked using Kocher’s classic DPA [1], that a 97% reduction in data processing can be achieved.

Ice accretion has a negative impact on critical infrastructure, as well as a range of commercial and residential activities. Icephobic surfaces are defined by an ice adhesion strength τice < 100 kPa. However, the passive removal of ice requires much lower values of τice, such as on airplane wings or power lines (τice < 20 kPa). Such low τice values are scarcely reported, and robust coatings tha...

We examine whether the Coase conjecture [7, 14, 4, 10] is robust against slight ability of commitment of the monopolist not to sell the durable goods to consumers. We quantify the commitment ability in terms of the speed that the durable goods perish, while keeping the time between the o ers small. We demonstrate that the slight commitment capability makes a substantial di erence by constructin...

A durable-goods monopolist may use quality degradation as a commitment not to lower price in the future. The introduction of damaged goods expedites lowvaluation consumers’ future demands, and helps the firm to mitigate the Coasian time-consistency problem. In such a case, damaged goods are more likely to be observed relative to the static setting where only the price-discrimination aspect of q...

Social life consists of making mistakes, then correcting them. The big questions do not concern who makes the fewest mistakes and why, but whether the mistakes are fruitful, how fast people recognize them, and how well they correct them. The same principles apply to writing books, even if the interaction and error-correction take longer to operate than in everyday conversation. This symposium’s...

We consider a cheap-talk game with one sender and one receiver. If the receiver does not commit to listen to only one message, the equilibrium refinements due to Farrell [5], Grossman and Perry [7] and Matthews, OkunoFujiwara and Postlewaite [11] are no longer applicable. We discuss different notions of durability and sequential credibility when a message can later be followed by more messages,...

BACKGROUND Serum infliximab trough levels correlate with efficacy; dose escalation is often beneficial in patients with Crohn's disease who stop responding to infliximab treatment. OBJECTIVE To carry out a post hoc analysis of A Crohn's Disease Clinical Trial Evaluating Infliximab in a New Long-term Treatment Regimen I (ACCENT I) to evaluate the association between serum infliximab trough lev...

Results are also compared to EN350-1. Results to date indicate that furfurylation and acetylation are capable of improving the durability classification of UK grown Sitka spruce from Not Durable, Durability Class (DC) 5 for control samples to Very Durable (DC1). More interestingly, lower durability classifications were obtained when using UK grown Scots pine, where the treated samples could be ...
