Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

Journal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Bilateral Absence of the Superior Vena Cava

Case Reports in Cardiology, 2012
Bilateral absence of the superior vena cava (SVC) is a very rarely detected, mainly asymptomatic congenital vascular anomaly. Though usually innocent, this anomaly may complicate cardiothoracic surgery and certain procedures like central venous catheter ...

Stability Enhancement with SVC

International Journal of Computer Applications, 2013
This paper deals with Power flow, which is necessary for any power system solution and carry out a comprehensive study of the NewtonRaphson method of power flow analysis with and without SVC. Voltage stability analysis is the major concern in order to operate any power system as secured.

AlloyDesignClaw: Optimizing Castability and Mechanical Properties of Nickel‐Based Superalloys

Materials Genome Engineering Advances, EarlyView.
A stepwise optimization method is proposed for castability and mechanical properties of nickel‐based superalloys, enabling interpretable dimensionality reduction and efficient multi‐objective optimization of the composition space. An alloy design multi‐agent framework was further developed, integrating large language models, CALPHAD calculation ...

Beyond the Pulmonary Veins: The Influence of Pulsed Field Ablation on the Superior Vena Cava

Journal of Arrhythmia
Background Pulsed field ablation (PFA) selectively ablates myocardial tissue while minimizing damage to surrounding structures. However, its effects on the superior vena cava (SVC) during right superior pulmonary vein (RSPV) isolation remain unclear ...

Prediction of Failure in Lithium‐Rich Cathode Half‐Cells Using Early‐Cycle Data

Materials Genome Engineering Advances, EarlyView.
Using a dataset constructed from the performance evolution of Li‐rich cathode materials, a GBDT‐based model was developed for early half‐cell failure prediction. By using only data from the first 50 cycles, the model enables rapid identification of failure tendencies and provides an efficient tool for performance screening and evaluation.

Duplication of the Superior Vena Cava in an Elderly Patient on Hemodialysis

International Journal of Gerontology, 2017
Summary: The prevalence of elderly patients who are dependent on hemodialysis (HD) has increased worldwide. We report the case of an 81-year-old man with end-stage renal disease who displayed a duplication of the superior vena cava (SVC) with bilateral ...

Emergencies in Amyotrophic Lateral Sclerosis

Muscle &Nerve, EarlyView.
ABSTRACT Emergencies are frequent in people living with amyotrophic lateral sclerosis (pALS), especially as the disease progresses, and can necessitate urgent evaluation and intervention. Progressive weakness in ALS inevitably increases fall risk, making discussion of fall prevention strategies integral to caring for pALS.

Superior vena cava syndrome in hemodialysis patient

Saudi Journal of Kidney Diseases and Transplantation, 2011
Obstruction of blood flow in the superior vena cava (SVC) results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung ...
