We present a method for correcting coherence gate curvature caused by scanning-induced path length variations in spectral-domain high-NA optical coherence imaging systems. These variations cause curvature artifacts in optical coherence tomography and effectively restrict the field of view in optical coherence microscopy (OCM). Here we show that the coherence gate curvature can be measured and c...

This paper presents the first comparison between repeat-pass coherence from ASAR and JERS-1 SAR. To reduce the influence of temporal decorrelation, repeat-pass pairs acquired during the winter season have been selected. ASAR 35day coherence and JERS-1 44-day coherence from six different test areas in Siberia and northern Europe have been evaluated. The results indicate that the decorrelation is...

Block coherence of matrices plays an important role in analyzing the performance of block compressed sensing recovery algorithms (Bajwa and Mixon, 2012). In this paper, we characterize two block coherence metrics: worstcase and average block coherence. First, we present lower bounds on worst-case block coherence, in both the general case and also when the matrix is constrained to be a union of ...

This presentation is about (i) formal, (ii) synchronic, (iii) epistemic (iv) coherence (v) requirements. (i) Formal coherence is to be distinguished from other sorts of coherence discussed in contemporary epistemology (e.g., in some empirical, truth/knowledge-conducive sense [1]). Ideally, whether a set of judgments is coherent (in the present sense) should (in principle) be determinable a prio...

Recent story completion studies (Arnold 2001, Rohde et al. 2006) show that passages exhibiting different coherence relations yield different patterns of pronoun interpretation. These results predict that a shift in the distribution of coherence relations in participant responses ought to induce a shift in the distribution of pronoun interpretations. Experiment 1 manipulates the coherence distri...

Having as a main motivation the development of robust and high performing robot vision systems that can operate in dynamic environments, we propose a bayesian spatiotemporal context-based vision system for a mobile robot with a mobile camera, which uses three different context-coherence instances: current frame coherence, last frame coherence and high level tracking coherence (coherence with tr...

Coherence theorems for covariant structures carried by a category have traditionally relied on the underlying term rewriting system of the structure being terminating and confluent. While this holds in a variety of cases, it is not a feature that is inherent to the coherence problem itself. This is demonstrated by the theory of iterated monoidal categories, which model iterated loop spaces and ...

Discourse coherence is strongly associated with text quality, making it important to natural language generation and understanding. Yet existing models of coherence focus on measuring individual aspects of coherence (lexical overlap, rhetorical structure, entity centering) in narrow domains. In this paper, we describe domainindependent neural models of discourse coherence that are capable of me...

Corticomuscular coherence has previously been reported between primary motor cortex (M1) and contralateral muscles. We examined whether such coherence could also be seen from somatosensory areas. Local field potentials (LFPs) were recorded from primary somatosensory cortex (S1; areas 3a and 2) and posterior parietal cortex (PPC; area 5) simultaneously with M1 LFP and forearm EMG activity in two...

Among many reasons for which contemporary philosophers take coherentism in epistemology seriously, the most important is probably the perceived inadequacy of alternative accounts, most notably misgivings about foundationalism. But coherentism also receives straightforward support from cases in which beliefs are apparently justified by their coherence. From the perspective of those against coher...
