Managed futures funds are predominantly trend-followers. By analyzing positioning data, we provide novel evidence for this claim and estimate signals applied by these funds. We write trend-followers aggregate position as a weighted sum of past daily returns use generalized ridge regression regularization parameter estimation. This procedure prevents overfitting but remains flexible enough to ca...

aortoenteric fistula is a rare but significant clinical entity associated with high morbidity and mortality if remain untreated. clinical presentation and imaging findings may be subtle and prompt diagnosis can be difficult. herein, we present a patient who initially presented with abdominal pain and computed tomography showed an aortic aneurysm compressing duodenum without any air bubbles. one...

We studied the development of surface instabilities leading to the generation of multielectron bubbles (MEBs) in superfluid helium upon the application of a pulsed electric field. We found the statistical distribution of the charge of individual instabilities to be strongly dependent on the duration of the electric field pulse. The rate and probability of generation of these instabilities in re...

Recent debate amongst some sections of the diving community has concerned the relative benefits of using new ascent and decompression strategies based on calculations of the presence and behaviour of microbubbles. This debate has extended to concern over the relative safety of standard entry level agency decompression/no stop tables. The concern stems from the fact that recent research and opin...

Speculative evaluation can improve the performance of parallel graph reduction systems through increased parallelism. Although speculation is costly, much of the burden can be absorbed by processors which would otherwise be idle. Despite the overhead required for speculative task management, our prototype implementation achieves 70% eeciency for speculative graph reduction, with little impact o...

In this paper, we argue that China's P2P lending is influenced by the behavioural factors of platforms. This because severe information asymmetry results in high uncertainty surrounding industry. Specifically, examine three aspects lending: sentiments, herding, and speculation. Using a sample 918 platforms from October 2015-September 2019, document positive news release media (sentiments) encou...

Shell and Tube heat exchangers are the heat exchangers that are most widely used in industries and for other commercial purposes. There are many techniques that have been utilized to enhance the heat transfer performance of the shell and tube heat exchangers. Air bubble injection is one of the promising and inexpensive techniques that can create turbulence in the fluids resulting in to enhancem...

In retrospect, the experimental findings on competitive market behavior called for a revival of old, classical, view competition as collective higgling and bargaining process (as opposed to price-taking behaviors) founded reservation prices (in place utility function). this paper, we specialize classical methodology deal with speculation, an important impediment price stability. The model invol...
