Characterization of Monolithic Active Pixel Sensors for future collider experiments [PDF]

open access: yesEPJ Web of Conferences
In high-energy physics experiments, Monolithic Active Pixel Sensors (MAPS) have become crucial components of vertex and tracking detectors over the past decade due to the integration of readout circuitry with the detection volume in a single chip.

Regulation of iron-siderophore uptake in a diazotrophic cyanobacterium Anabaena anabaena 7120

open access: yesThe Indian Journal of Agricultural Sciences, 2014
The regulation of 55Fe-siderophore uptake of was studied in a diazotrophic cyanobacterium Anabaena 7120. The uptake up to 20 min was found to be biphasic, a rapid first and steady second phase.

Time constant of double exponential signal for X-ray energy spectrum detector

open access: yesHe jishu, 2021
BackgroundIn the X-ray energy spectrum measurement system, the time constant is an important factor affecting trapezoidal pulse shaping. Accurate measurement of the time constant of double exponential pulse signals is beneficial to obtaining a better ...

Inter-Pixel Crosstalk in Teledyne Imaging Sensors (TIS) H4RG-10 Detectors

open access: yes, 2012
CMOS-hybrid arrays have recently surfaced as competitive optical detectors for use in ground- and space-based astronomy. One source of error in these detectors that does not appear in more traditional CCD arrays is the inter-pixel capacitance component ...

The light curve of SN 1987A revisited: constraining production masses of radioactive nuclides [PDF]

open access: yes, 2014
We revisit the evidence for the contribution of the long-lived radioactive nuclides 44Ti, 55Fe, 56Co, 57Co, and 60Co to the UVOIR light curve of SN 1987A.

A method to obtain radioactivity of non-γ nuclides by 60Co based on Monte Carlo simulations

open access: yesNuclear Engineering and Technology
Source term investigation is a critically important aspect of reactor decommissioning, particularly as the range of nuclides under consideration expands beyond the capabilities of existing analysis methods.

Presupernova collapse models with improved weak-interaction rates [PDF]

open access: yes, 2000
Improved values for stellar weak interaction rates have been recently calculated based upon a large shell model diagonalization. Using these new rates (for both beta decay and electron capture), we have examined the presupernova evolution of massive ...

Contact‐dependent iron uptake from dust revealed by elemental analysis of single Trichodesmium colonies

open access: yesLimnology and Oceanography, Volume 70, Issue 11, Page 3155-3171, November 2025.
Abstract Aerosol dust deposited on the nutrient‐deprived surface ocean can boost phytoplankton growth and oceanic carbon uptake. Low mineral solubility restricts the biological utilization of dust‐nutrients, thereby benefiting phytoplankton that actively dissolve dust.

Iron Is Filtered by the Kidney and Is Reabsorbed by the Proximal Tubule

open access: yesFrontiers in Physiology, 2021
The aim of this study was to determine the iron (Fe) concentration profile within the lumen of the S2 renal proximal convoluted tubule (PCT) and to resolve whether this nephron segment transported Fe.

Analysis of the low-energy electron-recoil spectrum of the CDMS experiment [PDF]

open access: yes, 2009
We report on the analysis of the low-energy electron-recoil spectrum from the CDMS II experiment using data with an exposure of 443.2 kg-days. The analysis provides details on the observed counting rate and possible background sources in the energy range
