A signature invariant for knotted Klein graphs

open access: yes, 2018
We define some signature invariants for a class of knotted trivalent graphs using branched covers. We relate them to classical signatures of knots and links.

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Comparison of the maximal inaccuracies for two experiments [PDF]

open access: yesComputer Science Journal of Moldova, 2017
In this paper we refine and generalize some previous our results on the inaccuracy (error) theory. We define conditions, which characterize different types of functions.

Leibnizova kontingencia nie je náhoda ani nahodilost

open access: yesFilosofický časopis, 2023
Conceptual exactitude is one of the appanages of philosophical thinking and metaphysical thinking specifically. A slight semantic nuance may, in the case of a particular philosophical concept, lead to inaccuracy of thought.

Inaccuracy in Traffic Forecasts

open access: yesTransport Reviews, 2006
This paper presents results from the first statistically significant study of traffic forecasts in transportation infrastructure projects. The sample used is the largest of its kind, covering 210 projects in 14 nations worth US$58 billion. The study shows with very high statistical significance that forecasters generally do a poor job of estimating the

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

From Bug to Feature: Harnessing Cross‐Sensitivity for Multiparametric Luminescence Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Cross‐sensitivity in luminescence sensing is reframed from a limitation into a resource for multiparametric detection. Using ruby microspheres as a model system, cross‐sensitivity is quantitatively assessed and exploited through linear discriminant analysis, enabling simultaneous, correction‐free pressure and temperature sensing with a single ...

Analytical performance evaluation of the Biosystems BA400 Clinical Chemistry Analyzer

open access: yesJournal of Associated Medical Sciences, 2015
Introduction: BA400 (Biosystems, Spain) is a new clinical chemistry analyzer for spectrophotometric, tubidimetric and ion-selective determination of biochemical analytes. Validation of method performance before routine operation is needed.

A method of solving inverse problem of electro-logging

open access: yesГеофизический журнал, 2012
A method of solving inverse problem of logging sounding has been proposed based on the possibility to take into account quantitative connection between a measurement inaccuracy and inversion inaccuracy.
