likelihood and the role of models in molecular phylogenetics.

by Mike Steel , David Penny - Mol. Biol. Evol. , 2000
"... Methods such as maximum parsimony (MP) are frequently criticized as being statistically unsound and not being based on any ''model.'' On the other hand, advocates of MP claim that maximum likelihood (ML) has some fundamental problems. Here, we explore the connection between the ..."

is the leading alternative, other approaches include distance-based methods that use transformed or inferred distances, for example, logdet/paralinear distances (see Nevertheless, ML methodology enjoys far from universal acceptance. Objections to ML include the following: Concern about the validity and exact

When and why incentives (don’t) work to modify behavior.

by Uri Gneezy , Stephan Meier , Pedro Rey-Biel - Journal of Economic Perspectives , 2011
"... addresses are <ugneezy@ucsd.edu>, <sm3087@columbia.edu>, and <pedro.rey@uab.cat>. 2 Economists often emphasize that "incentives matter." The basic "law of behavior" is that higher incentives will lead to more effort and higher performance: principals who are em ..."

1WEIGHTED PARTONOMY-TAXONOMY TREES WITH LOCAL SIMILARITY MEASURES FOR SEMANTIC BUYER-SELLER MATCH-MAKING

by Lu Yang, Marcel Ball, Virendrakumar C. Bhavsar, Harold Boley
"... A semantically enhanced weighted tree similarity algorithm for buyer-seller match-making is presented. First, our earlier global, structural similarity measure over (product) partonomy trees is enriched by taxonomic semantics: Inner nodes can be labeled by classes whose partial subsumption order is ..."

into the partonomy tree (as a “Classification ” branch) in a way that allows us to directly reuse our partonomy similarity algorithm and to permit weighted (or 'fuzzy') taxonomic subsumption with no added effort. Second, leaf nodes can be typed and each type is associated with a local, special

ACCEPTED FOR PUBLICATION IN ASTROPHYSICAL JOURNAL LETTERS Preprint typeset using L ATEX style emulateapj v. 25/04/01 ON THE ASSEMBLY HISTORY OF EARLY-TYPE GALAXIES IN THE HUBBLE DEEP FIELD NORTH 1,2

by Pieter G. Van Dokkum, Richard S. Ellis , 2003
"... We present deep Keck spectroscopy for a sample of I814 < 22.5 field early-type galaxies selected morphologically in the redshift range 0.56 ≤ z ≤ 1.02 in the Hubble Deep Field North (HDF-N). Using velocity dispersions determined from the Keck spectra in conjunction with structural parameters meas ..."

Submitted to: MSFP 2014 Koka: Programming with Row-polymorphic Effect Types

by Daan Leijen
"... We propose a programming model where effects are treated in a disciplined way, and where the potential side-effects of a function are apparent in its type signature. The type and effect of expres-sions can also be inferred automatically, and we describe a polymorphic type inference system based on H ..."

U.: Feeding preferences of abyssal macrofauna inferred from in situ pulse chase experiments

by R M Jeffreys , C Burke , A J Jamieson , B E Narayanaswamy , H A Ruhl - PloS ONE
"... Abstract Climatic fluctuations may significantly alter the taxonomic and biochemical composition of phytoplankton blooms and subsequently phytodetritus, the food source for the majority of deep-sea communities. To examine the response of abyssal benthic communities to different food resources we si ..."

However, incorporation levels of both diatom C and cocco N were low (,0.05% and 0.005% of the added C and N). Incorporation of labelled diatoms was similar during both June and September suggesting

by Workshop Pyrosetta
"... Rosetta is a suite of algorithms for biomolecular structure prediction and design. Rosetta is written in C++ and is available from www.rosettacommons.org. PyRosetta is a toolkit in the programming language Python, which encapsulates the Rosetta functionality by using the compiled C++ libraries. Pyth ..."

. Python is an easy language to learn and also includes modern programming approaches such as objects. It can be used via scripts and also interactively as a command-line program, similar to MATLAB The goals of this first workshop are (1) to have you learn to use PyRosetta both interactively and by writing

Categorization under complexity: A unified MDL account of human learning of regular and irregular categories

by David Fass, Jacob Feldman - In Advances in Neural Information Processing Systems 15 , 2002
"... We present an account of human concept learning-that is, learning of categories from examples-based on the principle of minimum descrip-tion length (MDL). In support of this theory, we tested a wide range of two-dimensional concept types, including both regular (simple) and highly irregular (complex ..."

It has been variously suggested that the underlying prin-ciple might be the similarity structure of objects [1], the manipulability of decision bound~ aries [2], or Bayesian inference [3][4].
