Information Is Where You Find It: Perception as an Ecologically Well-Posed Problem

Information Is Where You Find It.

A basic problem of foraging is how to obtain information about the location and quality of food. Relevant information is obtained from immediate stimulation, from previous sensory experience stored in memory, and through the genes. Apparently, even the simplest organisms can use information from all these sources. A good example comes from infective juveniles of the plant-parasitic nematode Mel...

The Well - Posed Problem

Many statistical problems, including some of the most important for physical applications, have long been regarded as underdetermined from the standpoint of a strict frequency de nition of probability; yet they may appear well posed or even overdetermined by the principles of maximum entropy and transformation groups. Furthermore, the distributions found by these methods turn out to have a de n...

Where to Find Information

Where do you Find Interesting Biosurveillance Publications?

Introduction The ISDS Research Committee (RC) is an interdisciplinary group of researchers interested in a wide range of topics related to disease surveillance. The RC hosts a literature review process that results in a permanent repository1 of relevant journal articles; some of which are presented in bi-monthly calls/webinars that provide a forum for discussion and author engagement.2 The webi...

Return to Where? You Can’t Exploit What You Can’t Find

So far, no countermeasure has been able to fully prevent sophisticated exploitation techniques such as return-oriented programming (ROP). Recent control-flow integrity (CFI) defenses from Google and Microsoft can be bypassed by constructing a ROP payload that adheres to the control-flow constraints or by exploiting implementation flaws to bypass the control-flow checks. Microsoft’s EMET has les...
