The functional causes of life history trade-offs have been a topic of interest to evolutionary biologists for over six decades. Our review of life history trade-offs discusses conceptual issues associated with physiological aspects of trade-offs, and it describes recent advances on this topic. We focus on studies of four model systems: wing polymorphic insects, Drosophila, lizards, and birds. T...

We initiate the study of provably secure remote memory attestation. We present two protocols offering various efficiency and security trade-offs that detect the presence of injected malicious code in remotelystored heap memory. While our solutions offer protection only against a specific class of attacks, our novel formal security definitions are general enough to cover a wide range of attacks ...

Viruses can suffer 'life-history' trade-offs that prevent simultaneous improvement in fitness traits, such as improved intrahost reproduction at the expense of reduced extrahost survival. Here we examine reproduction-survival trade-offs and other trait compromises, highlighting that experimental evolution can reveal trade-offs and their associated mechanisms. Whereas 'curse of the pharaoh' (hig...

A quadtree-based triangulation, sometimes called an RTIN, is a common hierarchical representation of terrain for 3D visualization. In this paper we focus on the memory/error bound trade-offs for using RTINs with planar and quadratic surface patches over triangles.

Memory access is the major bottleneck of today's high-performance microprocessors. This thesis provides a systematic and quantitative analysis of the performance trade-offs of major cache (fast memory) topologies. It allows early insight into these trade-offs because performance and costs are controlled by circuit and layout level issues which are difficult to evaluate at initial stages in a de...

Trade-offs among functional traits are essential for explaining community structure and species coexistence. While two-way trade-offs have been investigated in many systems, higher-dimensional trade-offs remain largely hypothetical. Here we demonstrate a three-way trade-off between cell size and competitive abilities for nitrogen and phosphorus in marine and freshwater phytoplankton. At a given...

Lattice-based cryptography is one of the leading proposals for post-quantum cryptography. The Shortest Vector Problem (SVP) arguably most important problem cryptanalysis lattice-based cryptography, and many schemes have security claims based on its hardness. best quantum algorithm SVP due to Laarhoven [] runs in (heuristic) time \(2^{0.2653d + o(d)}\). In this article, we present an improvement...

Specialization and concomitant trade-offs are assumed to underlie the non-neutral coexistence of lineages. Trade-offs across heterogeneous environments can promote diversity by preventing competitive exclusion. However, the importance of trade-offs in maintaining diversity in natural microbial assemblages is unclear, as trade-offs are frequently not detected in artificial evolution experiments....
