A deeper understanding of the mechanical behavior of ultra-fine (UF) and nanocrystalline (NC) grained metals is necessary with the growing interest in using UF and NC grained metals for structural applications. The cyclic deformation response and behavior of UF and NC grained metals is one aspect that has been gaining momentum as a major research topic for the past ten years. Severe Plastic Def...

Fine-grained cryptographic primitives are ones that are secure against adversaries with an apriori bounded polynomial amount of resources (time, space or parallel-time), where the honest algorithms use less resources than the adversaries they are designed to fool. Such primitives were previously studied in the context of time-bounded adversaries (Merkle, CACM 1978), space-bounded adversaries (C...

In theory, join points can be arbitrary places in the structure or execution of a program. However, most existing aspect languages do not support the full expressive power of this concept, limiting their pointcut languages to a subset of the theoretically possible join points. In this paper we explore a minimal language design based on only three built-in fine-grained pointcuts, which enable ex...

Traditional approaches to receiver-driven layered multicast have advocated the benefits of cumulative layering, which can enable coarse-grained congestion control that complies with TCP-friendliness equations over large time scales. In this paper, we quantify the costs and benefits of using non-cumulative layering and present a new, scalable multicast congestion control scheme which provides a ...

Fuzzing is a popular software testing method that discovers bugs by massively feeding target applications with automatically generated inputs. Many state-of-art fuzzers use branch coverage as feedback metric to guide the fuzzing process. The fuzzer retains inputs for further mutation only if increased. However, provides shallow sampling of program behaviours and hence may discard interesting mu...

An important task in information access methods is distinguishing factual information from speculative or negated information. Fine-grained certainty levels of diagnostic statements in Swedish clinical text are annotated in a corpus from a medical university hospital. The annotation model has two polarities (positive and negative) and three certainty levels. However, there are many e-health sce...

Establishing visual correspondence across images is a challenging and essential task. Recently, an influx of self-supervised methods have been proposed to better learn representations for correspondence. However, we find that these often fail leverage semantic information over-rely on the matching low-level features. In contrast, human vision capable distinguishing between distinct objects as p...
