Canadian Covid-19 pandemic public health mitigation measures at the province level

open access: yesScientific Data, 2023
The Covid-19 pandemic has prompted governments across the world to enforce a range of public health interventions. We introduce the Covid-19 Policy Response Canadian tracker (CPRCT) database that tracks and records implemented public health measures in ...

MODELING MODELING [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1999
Models are tools; they need to fit both the hand and the task. Presence or absence of a feature such as a pacemaker or a cascade is not in itself good. Or bad. Criteria for model evaluation involve benefit‐cost ratios, with the numerator a function of the range of phenomena explained, goodness of fit, consistency with other nearby models, and ...

Modeling Model Slicers [PDF]

open access: yes, 2011
Among model comprehension tools, model slicers are tools that extract a subset from a model, for a specific purpose. Model slicers are tools that let modelers rapidly gather relevant knowledge from large models. However, existing slicers are dedicated to one modeling language. This is an issue when we observe that new domain specific modeling languages

Modelling ethnogenesis [PDF]

open access: yesBiosystems, 2022
Following the ideas of L.N.Gumilev, we introduce the mathematical model of ethnogenesis which describes the dynamics of subgroups in the developing polity in terms of ordinary differential equations. The bust dynamics associated with the rise and fall of civilisations is modelled as an excitation process, which is the non-linear phenomenon, well known ...

Insights from mathematical modelling and quantitative analysis on the proposed WHO 2030 targets for visceral leishmaniasis on the Indian subcontinent [version 1; peer review: 2 approved]

open access: yesGates Open Research, 2019
Visceral leishmaniasis (VL) is a neglected tropical disease (NTD) caused by Leishmania protozoa that are transmitted by female sand flies. On the Indian subcontinent (ISC), VL is targeted by the World Health Organization (WHO) for elimination as a public

Frequent and unpredictable changes in COVID-19 policies and restrictions reduce the accuracy of model forecasts

open access: yesScientific Reports, 2023
Between June and August 2020, an agent-based model was used to project rates of COVID-19 infection incidence and cases diagnosed as positive from 15 September to 31 October 2020 for 72 geographic settings.

Modelling probabilistic cache representativeness in the presence of arbitrary access patterns [PDF]

open access: yes, 2016
Measurement-Based Probabilistic Timing Analysis (MBPTA) is a promising powerful industry-friendly method to derive worst-case execution time (WCET) estimates as needed for critical real-time embedded systems.

Modeling needs user modeling

open access: yesFrontiers in Artificial Intelligence, 2023
Modeling has actively tried to take the human out of the loop, originally for objectivity and recently also for automation. We argue that an unnecessary side effect has been that modeling workflows and machine learning pipelines have become restricted to only well-specified problems.

Protocol for the production of micro- and nanoplastic test materials

open access: yesMicroplastics and Nanoplastics, 2023
Micro- and nanoplastics (MNP) are ubiquitous, but little is known about the risks they pose to human health. Currently available data are of limited use for developing relevant risk assessments due to poor quality control, the lack of a standardised ...
