Water Vapour Effects in Mass Measurement

open access: yesMeasurement Science Review, 2008
Water vapour inside the mass comparator enclosure is a critical parameter. In fact, fluctuations of this parameter during mass weighing can lead to errors in the determination of an unknown mass.

Size-dependent Vibration Analysis of Non-uniform Mass Sensor Nanobeams [PDF]

open access: yesMechanics of Advanced Composite Structures, 2021
In the present paper, the exact modeling and frequency analysis of the mass sensor nanobeam are investigated based on a higher-order elasticity theory with taking into account the longitudinal discontinuity. The energy equations of the beam are expressed

Quark Mass Effects in JIMWLK Evolution [PDF]

open access: yesEPJ Web of Conferences, 2022
Quark mass effects in the Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) evolution appear at the next to leading order (NLO) of QCD, i.e., at 𝒪(α2s) of the QCD coupling for the JIMWLK evolution kernels.

Hydrochemical and Seasonally Conditioned Changes of Microbial Communities in the Tufa-Forming Freshwater Network Ecosystem

open access: yesmSphere, 2023
Freshwater network ecosystems consist of interconnected lotic and lentic environments within the same catchment area. Using Plitvice Lakes as an example, we studied the changes in environmental conditions and microbial communities (bacteria and fungi ...

Connectivity of communities interacts with regional heterogeneity in driving species diversity: a mesocosm experiment

open access: yesEcosphere, 2021
According to metacommunity theory and previous experiments, inter‐patch dispersal rates may alter species diversity at local to regional scales. In this study, we tested the predictions of metacommunity theory regarding the effect of dispersal rates on ...

Metacommunity Structure of Stream Insects across Three Hierarchical Spatial scales

open access: yesEcology and Evolution, 2020
A major challenge in community ecology is to understand the underlying factors driving metacommunity (i.e., a set of local communities connected through species dispersal) dynamics.
