Thunderstorm total lightning activity behavior associated with transmission line trip events of power system

open access: yesnpj Climate and Atmospheric Science
High-voltage transmission lines are susceptible targets for lightning strikes. It is an interesting topic how the trip event of transmission line is related to the area, location, and intensity of thunderstorms occurring at that time and that place ...

Terrain Effects on Time-Frequency Characteristics of Negative Return Stroke Electric Fields: A Path-Incremental Method

open access: yesRemote Sensing
Waveforms recorded by lightning location networks mix source variability with propagation effects, making terrain-associated distortion difficult to isolate.

Seasonal Influences on the Impulse Characteristics of Grounding Systems for Tropical Countries

open access: yesEnergies, 2019
One of the most important parameters of the performance of grounding systems is the soil resistivity. As generally known, the soil resistivity changes seasonally, hence the performance of grounding systems, at DC and under high impulse conditions.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

open access: yesMolecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Incompatibilism and the Principle of Sufficient Reason in Kant’s 'Nova Dilucidatio'

open access: yesJournal of Modern Philosophy, 2022
The consensus is that in his 1755 'Nova Dilucidatio', Kant endorsed broadly Leibnizian compatibilism, then switched to a strongly incompatibilist position in the early 1760s.

Ground confluence [PDF]

open access: yes, 1987
In this paper we introduce a test for confluence on ground terms. This test allows us to prove the ground confluence of term rewriting systems where the Knuth-Bendix Algorithm does not terminate. Ground Confluence of term rewriting systems is sufficient, if one is interested in congruences on ground terms.

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

open access: yesMolecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

open access: yesHigh Voltage
Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed
