We throw some light on the question: is there a MAD family (= a maximal family of infinite subsets of N, the intersection of any two is finite) which is saturated (= completely separable i.e. any X ⊆ N is included in a finite union of members of the family or includes a member (and even continuum many members) of the family). We prove that it is hard to prove the consistency of the negation: (a...

In a relatively short period, enterprise networks have evolved from small-sized LANs with simple architectures, to present day large networks with very complex architectures. Their topologies now include combinations of Local Area Networks (LANs), Wireless access networks, Metropolitan Area Networks (MANs), Wide Area Networks (WANs) and Virtual Private Networks (VPNs) that often span across mul...

A man may receive a blow upon liis lieart or liis imagination as lie may receive an injury to liis brain, wliicli till, if ever, tlie effects have passed away, shall determine an eccentricity of conduct in all after-life, for which he is wholly, or in a considerable degree, irresponsible. Such a man is pro tanto to be pitied, and, if needful, shut up. If his eccentricity be of dangerous tendenc...

A t the Flemish Institute for Biotechnology (VIB), the PhD students organize an international symposium every 2 years. The authors of this article were all members of the organizing committee this year, and we are proud of the programme on offer, which includes a Nobel Prize winner and many other eminent speakers. Organizing the symposium has been a valuable experience for us, and a worthy addi...

In this article, we analyze a system modeling bacteriophage treatments for infections in a noisy context. In the small noise regime, we show that after a reasonable amount of time the system is close to a sane equilibrium (which is a relevant biologic information) with high probability. Mathematically speaking, our study hinges on concentration techniques for delayed stochastic differential equ...

Objectives: To evaluate how surgical trends, costs, and outcomes for anterior cruciate ligament reconstruction (ACLR) vary with patient age. Design: Retrospective Cohort Study Setting: Outpatient Ambulatory Surgery Center Patients: 587 primary ACLR patients from 2009-2016. Inclusion criteria consisted of ACLR, complete preoperative two-year post-operative reported outcome (PRO) data. Patients w...
