Multivariate optimization for the development of a sample preparation procedure and evaluation of trace elements in plastic toys

open access: yesJournal of Trace Elements and Minerals
Background: Due to the rigidity and resistance caused by formation of bonds between polymer chains, plastic toys are complex matrices. Objective: This study was Doehlert design for reagent optimization proportions employing microwave-assisted digestion ...

Boys and Their Toys? Masculinity, Technology, and Work [PDF]

open access: yesInternational Labor and Working-Class History, 1998
workers' objections to protective policies in American industries during World War Two. Arwen Mohun (University of Delaware) addressed the provocative question of why workers sometimes willingly risked their health, discussing the "calculus of risk" as a social construct shaped by both labor and capital.

How do you Play with a Robotic Toy Animal? A long-term study of Pleo [PDF]

open access: yes, 2010
Pleo is one of the more advanced interactive toys currently available for the home market, taking the form of a robotic dinosaur. We present an exploratory study of how it was interacted with and reflected upon in the homes of six families during 2 to 10

Simulating a toy model of electrodynamics in (1 + 1) dimensions [PDF]

open access: yes, 2009
We show how to simulate a toy model of electrodynamics in (1+1) dimensions and describe several numerical experiments. The toy model is much simpler than ordinary electrodynamics, but shares many of the same physical features.

Sequential Monte Carlo with likelihood tempering and parallel implementation for uncertainty quantification

open access: yesAIChE Journal, EarlyView.
Abstract Bayesian estimation enables uncertainty quantification, but analytical implementation is often intractable. As an approximate approach, the Markov Chain Monte Carlo (MCMC) method is widely used, though it entails a high computational cost due to frequent evaluations of the likelihood function.

Toys in Trade: Playfully Poetic Technology in Qing Dynasty Canton

open access: yesJournal of Early Modern History, 2022
Abstract The article explores how an artisan community in Canton adapted European clock-making technology to the making of automata in a Chinese aesthetic style. Moreover, it positions a unique automaton from the National Museum of Denmark in relation to a Chinese story and connected drinking game.

Interactive Prompt‐Guided Robotic Grasping for Arbitrary Objects Based on Promptable Segment Anything Model and Force‐Closure Analysis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A laser pointer‐guided robotic grasping method for arbitrary objects based on promptable segment anything model and force‐closure analysis is presented. Grasp generation methods based on force‐closure analysis can calculate the optimal grasps for objects through their appearances. However, the limited visual perception ability makes robots difficult to

The cost-effectiveness of increasing hepatitis Delta testing for individuals co-infected with HBV and HIV in the Netherlands

open access: yesInternational Journal of Infectious Diseases
Objectives: Chronic hepatitis D virus (HDV) infection accelerates liver‐related morbidity and mortality in people living with HIV and hepatitis B virus (HBV). In the Netherlands, HDV testing among HIV/HBV-coinfected adults is currently limited.
