Exploring the impact of measurement error in police recorded crime rates through sensitivity analysis

open access: yesCrime Science, 2023
It is well known that police recorded crime data is susceptible to substantial measurement error. However, despite its limitations, police data is widely used in regression models exploring the causes and effects of crime, which can lead to different ...

Inference of microbial recombination rates from metagenomic data. [PDF]

open access: yesPLoS Genetics, 2009
Metagenomic sequencing projects from environments dominated by a small number of species produce genome-wide population samples. We present a two-site composite likelihood estimator of the scaled recombination rate, rho = 2N(e)c, that operates on ...

Approximation Algorithms for Wireless Link Scheduling with Flexible Data Rates [PDF]

open access: yes, 2012
We consider scheduling problems in wireless networks with respect to flexible data rates. That is, more or less data can be transmitted per time depending on the signal quality, which is determined by the signal-to-interference-plus-noise ratio (SINR ...

Can almond trees directly dictate their irrigation needs?

open access: yesCalifornia Agriculture, 2003
Many of California's fruit and nut growers have already embraced more efficient irrigation systems (drip and microsprinkler) and adopted scientific irrigation-scheduling methods that closely match net applied water to evapotranspiration

Analyzing the effect of bank performance on stock price returns: empirical evidence from European high-income countries [PDF]

open access: yesBanks and Bank Systems
Banking performance has developed rapidly accompanied by technological advances that can simplify banking services and transactions by adopting a priority scale aimed at identifying dynamically moving stock price returns and exploring banking quality and

Enthalpy of the N+ + H2 → NH+ + H Reaction—Experimental Study of the Reverse Process

open access: yesThe Astrophysical Journal, 2023
The formation of nitrogen hydrides in the interstellar medium is initiated by the nearly thermoneutral reaction of N ^+ + H _2 → NH ^+ + H. Here, we experimentally determine the enthalpy of this reaction using the principle of detailed balance from a ...

A Fuzzy Random Survival Forest for Predicting Lapses in Insurance Portfolios Containing Imprecise Data

open access: yesMathematics, 2022
We propose a fuzzy random survival forest (FRSF) to model lapse rates in a life insurance portfolio containing imprecise or incomplete data such as missing, outlier, or noisy values.

Coherent transient data-rate conversion and data transformation [PDF]

open access: yesOptics Letters, 2000
Temporal compressions of optical pulses and pulse trains have been performed by the photon-echo process in Tm-doped YAG at 793 nm. Single-pulse temporal compression by almost a factor of 500 from 10 micros to 22 ns and pulse train compression by a factor of 14 from 5micros to 350 ns with a high-speed frequency-tunable external-cavity diode laser are ...
