Criterion-robust designs for the models of spring balance weighing [PDF]

Tatra Mountains Mathematical Publications, 2012
ABSTRACT In the paper we consider the linear regression model of the first degree on the vertices of the d-dimensional unit cube and its extension by an intercept term, which can be used, e.g., to model unbiased or biased weighing of d objects on a spring balance.

On certain A-optimal biased spring balance weighing designs

Statistics in Transition new series, 2014
In the paper, the estimation of unknown measurements of p objects in the experiment, according to the model of the spring balance weighing design, is discussed. The weighing design is called biased if the first column of the design matrix has elements equal to one only.

Highly D‑efficient Weighing Design and Its Construction

Acta Universitatis Lodziensis. Folia Oeconomica, 2017
In this paper, some aspects of design optimality on the basis of spring balance weighing designs are considered. The properties of D‑optimal and D‑efficiency designs are studied.

Preliminary Testing of a Passive Exoskeleton Prototype Based on McKibben Muscles

Machines
Upper-limb exoskeletons for industrial applications can enhance the comfort and productivity of workers by reducing muscle activity and intra-articular forces during overhead work.

Highly D-Efficient Weighing Designs for an Even Number of Objects

Revstat Statistical Journal, 2018
In this paper we formulate how to add a = 1, 2, 3 runs to a near D-optimal weighing design to get a highly D-efficient weighing design when the number of objects p is even.

Regular A-optimal spring balance weighing designs with correlated errors

Hacettepe Journal of Mathematics and Statistics, 2014
The problems linked with an E-optimal spring balance weighing design with correlated errors are discussed. The topic is focus on the determining the maximal eigenvalue of the inverse of the information matrix of estimators. The constructing method of the E-optimal design, based on the incidence matrices of balanced incomplete block designs, is ...

Catalogue of selected experimental plans

Biometrical Letters, 2021
Summary There are many works in the literature on the construction of experimental plans based on weighing designs. Hence, it is useful to compile a catalogue of experimental designs with specific properties.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Relations between regular A-optimal chemical and spring balance weighing designs with diagonal covariance matrix of errors [PDF]

Biometrical Letters, 2013
Summary In this paper, we study the relationships between regular A-optimal spring balance weighing designs and regular A-optimal chemical balance weighing designs. We give the basic relation between these designs in the case where the errors are uncorrelated and they have different variances.

Why human connection is the true metric of research success

FEBS Open Bio, EarlyView.
Human‐centred mentorship can be shaped by mentor attributes, actions, intrinsic drive and career ambition. Drawing on reflections across Singapore and France, as well as workshop insights from FEBS‐IUBMB ENABLE 2024, this article shows that human‐centred mentorship creates the conditions for sustainable growth, well‐being and retention in research ...
