The Effect of Ground Motion Selection Methods for Seismic Design of Tall Buildings: A Case Study of Mandalay City

Walailak Journal of Science and Technology, 2020
The near-fault earthquakes ground motion usually observed a few kilometers away from the active faults generally contains high energetic velocity pulses as a consequence of directivity effects.

Tuned Mass Dampers for Response Reduction of a Reinforced Concrete Chimney Under Near-Fault Pulse-Like Ground Motions

Frontiers in Built Environment, 2020
The article investigates response mitigation of a reinforced concrete (RC) chimney subjected to pulse-like near-fault ground motions using tuned mass damper (TMD) schemes. The total height of the chimney is 265 m with a mass of 11,109 ton.

Recurrent neural network-based seismic slope displacement hazard assessment considering the effects of slope aspects

Geomatics, Natural Hazards & Risk
Directionality of ground motion with respect to faulting is crucial if directivity pulse-like effects are observed; as a result, ground motion along slope sliding directions with pulse-like effects has a significant impact on slope stability during ...

Inelastic displacement ratio for rocking buildings subjected to far-field and near-field pulse-like ground motions [PDF]

Journal of Structural and Construction Engineering, 2019
Self centering rocking buildings are capable of reducing permanent damage and concentrating damage to replaceable energy dissipation devices. This paper aims to calculate inelastic displacement ratio for self centering rocking buildings under far field ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

A hybrid method to identify pulse-like ground motions and pulse periods based on ST-CNN

Yantu gongcheng xuebao
The rapid and precise identification of the pulse-like ground motions is a key challenge that perplexes both the academic and engineering communities. The quantitative identification methods can overcome the empirical limitations of manual identification.
