Critical light scattering in liquids [PDF]
, 2000 We compare theoretical results for the characteristic frequency of the Rayleigh peak calculated in one-loop order within the field theoretical method of the renormalization group theory with experiments and other theoretical results. Our expressions describe the non-asymptotic crossover in temperature, density and wave vector.

Compositionality and Model-Theoretic Interpretation
Journal of Logic, Language and Information, 2000 The present paper studies the general implications of the principle of compositionality for the organization of grammar. It will be argued that Janssen's (1986) requirement that syntax and semantics be similar algebras is too strong, and that the more liberal requirement that syntax be interpretable into semantics leads to a formalization that can be ...

Theoretical models in nuclearastrophysics [PDF]
Proceedings of XXXIV edition of the Brazilian Workshop on Nuclear Physics — PoS(XXXIV BWNP), 2012 We review different models used in nuclear astrophysics. Definitions of the relevant cross sections and reaction rates are presented. In particular the role of the R-matrix theory and of microscopic cluster models is emphasized. We discuss three applications: R-matrix fits of the12C(α,γ)16O E2 S factor, microscopic cluster calculations of the7Be(p,γ)8B

Are Model Organisms Theoretical Models? [PDF]
Disputatio, 2017 Abstract This article compares the epistemic roles of theoretical models and model organisms in science, and specifically the role of non-human animal models in biomedicine. Much of the previous literature on this topic shares an assumption that animal models and theoretical models have a broadly similar epistemic role—that of indirect ...

Synthetic Mutualism and the Intervention Dilemma
Life, 2019 Ecosystems are complex networks of interacting individuals co-evolving with their environment. As such, changes to an interaction can influence the whole ecosystem. However, to predict the outcome of these changes, considerable understanding of processes

Competitive Machine Learning: Best Theoretical Prediction vs Optimization [PDF]
arXiv, 2018 Machine learning is often used in competitive scenarios: Participants learn and fit static models, and those models compete in a shared platform. The common assumption is that in order to win a competition one has to have the best predictive model, i.e., the model with the smallest out-sample error. Is that necessarily true?

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose To compare image quality and clinical utility of a T2‐weighted (T2W) 3‐dimensional (3D) fast spin echo (FSE) sequence using deep learning reconstruction (DLR) versus conventional reconstruction for rectal magnetic resonance imaging (MRI).

An Information-Theoretic Model for Steganography
Information and Computation, 1998 AbstractAn information-theoretic model for steganography with a passive adversary is proposed. The adversary’s task of distinguishing between an innocent cover message C and a modified message S containing hidden information is interpreted as a hypothesis testing problem.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose/objectives Recent technological advancements have increased efficiency for clinical deliverability of online‐adaptive‐radiotherapy (oART). Previous cone‐beam‐computed‐tomography (CBCT) generations lacked the ability to provide reliable Hounsfield‐units (HU), thus requiring oART workflows to rely on synthetic‐CT (sCT) images derived ...
