To Root or Not to Root? The Economics of Jailbreak [PDF]
SSRN Electronic Journal, 2013 Abstract We construct a structural model that allows us to jointly estimate the demand for smartphones and paid apps using a Bayesian approach. Our data comes from more than 500 college students in Hong Kong and Shanghai. We find that the utility cost rather than the upfront monetary cost of jailbreaking smartphones determines its prevalence.

A root is a root is a root? Water uptake rates of Citrus root orders [PDF]
Plant, Cell & Environment, 2010 ABSTRACTKnowledge about the physiological function of root orders is scant. In this study, a system to monitor the water flux among root orders was developed using miniaturized chambers. Different root orders of 4‐year‐old Citrus volkameriana trees were analysed with respect to root morphology and water flux.

SSRN Electronic Journal, 2017 Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of humans from Africa tens of thousands of years ago, contributed to the differential ...

Different root growth patterns in tomato seedlings grown hydroponically under an electric field [PDF]
, 2013 Electric fields can determine changes at morphological and physiological levels in plants. In this study, seedlings of Solanum lycopersicum L., grown hydroponically in a floating system, were exposed to a DC 12.0 V m–1 electric field (EF).

Systematic Biology, 2012 The estimation of phylogenetic relationships is an essential component of understanding evolution. Accurate phylogenetic estimation is difficult, however, when internodes are short and old, when genealogical discordance is common due to large ancestral effective population sizes or ancestral population structure, and when homoplasy is prevalent ...

Frontiers in Plant Science, 2021 Cassava production and productivity in Eastern, Central, and Southern Africa are ravaged by cassava brown streak disease (CBSD), causing yield losses of up to 100% when susceptible varieties are grown.

, 2006 A wide range of counting and occurrence constraints can be specified with just two global primitives: the Range constraint, which computes the range of values used by a sequence of variables, and the Roots constraint, which computes the variables mapping onto a set of values. We focus here on the Roots constraint.

The Arabidopsis Book, 2014 Roots hairs are cylindrical extensions of root epidermal cells that are important for acquisition of nutrients, microbe interactions, and plant anchorage. The molecular mechanisms involved in the specification, differentiation, and physiology of root hairs in Arabidopsis are reviewed here.

Root Vertex Valency Distributions of Rooted Maps and Rooted Triangulations
European Journal of Combinatorics, 1994 We obtain the asymptotic distributions of root vertex valencies for rooted maps and rooted triangulations on general surfaces. We show that the asymptotic distributions are independent of the surface.
