Hyperproperties are becoming the, de facto, standard for reasoning about systems executions. They differ from classical trace properties since they are represented by sets of sets of executions instead of sets of executions. In this paper, we extend and lift the hierarchy of semantics developed in 2002 by P. Cousot in order to cope with verification of hyperproperties. In the standard hierarchy...

Ultrasonography represents the method of choice in the investigation of the female pelvis. An accurate interpretation of the images must take into consideration the specific features of the uterus, ovaries and fallopian tubes. The present case review aims to demonstrate important points in interpretation and management of the female pelvis images.

A three-month longitudinal case study is reported of a L2 learner's response to corrective feedback. While the major bulk of evidence indicates that correction on the whole has positive effects on the particular learner's learning, there is also evidence contradicting the popular assumption that feedback is always semantically transparent with respect to the learning problem. Confronted with co...

primary hepatic lymphoma is a rare malignancy usually presenting with symptoms of fever, hepatomegaly, jaundice and weight loss. this picture mimics infectious and inflammatory disorders and thus delays the diagnosis. here, we present a 47-year old man with prolonged fever who underwent several investigations and, in the meantime, developed fulminant hepatic failure before the diagnosis could b...

Without an existing large-scale coherent magnetic field in the early universe, Population III stars would likely rotate at or near breakup speed. In this work, focusing on accretion phase of stars, we investigate possibility generating a through dynamo processes, as well corresponding saturation level. Using results from hydrodynamic simulations performed with cylindrical grid, demonstrate that...

The design of large open steel piles driven at chalk sites suffers from considerable uncertainty, leading to major difficulties in many significant onshore and offshore projects. This paper describes recent instrumented driving, monotonic testing failure, restrike tests conducted on primarily low- medium-density a site North-western France. experiments are described interpreted with reference h...

The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.
