Evaluation of Aerodynamic and Sonic Boom Performance of Supersonic Transport Aircrafts with Multiple Wing Configurations

Aerospace
In this study, two-dimensional airfoil shapes obtained in aerodynamic optimizations are converted to three-dimensional wing models and then their aerodynamic and sonic boom performance are evaluated. The airfoil shapes analyzed are the diamond, Busemann,

Left atrial volume quantification using cardiac MRI in atrial fibrillation: comparison of the Simpson’s method with biplane area-length, ellipse, and three-dimensional methods

Diagnostic and Interventional Radiology, 2013
PURPOSELeft atrial volume is an important predictor of future arrhythmias, and it can be assessed by several different methods. Simpson’s method is well accepted as a reference standard, although no standardization exists for cardiac magnetic resonance ...

Segmental Snare Traction Technique for Helix‐Fixed Leadless Pacemaker Implantation Across a Repaired Tricuspid Annulus

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Helix‐fixed leadless pacemaker delivery can be challenging after tricuspid annuloplasty with a rigid ring. An 80‐year‐old woman with prior mitral valve repair, tricuspid annuloplasty (26‐mm MC ring), and Maze III surgery presented with syncope due to atrial fibrillation with a slow ventricular response. Standard maneuvers failed to advance the

Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

Pacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Sinking performance of new biplane depressor for constant-depth ichthyoplankton sampler at horizonal sampling

Aquaculture and Fisheries
A constant-depth ichthyoplankton sampler is vital equipment for monitoring fish recruitment and assessing fishery stocks. Its depressor, a critical component, maintains towing stability during sampling by balancing the sinking force of the depressor and ...

LLM‐Assisted Topic Modelling for Hate Speech Characterization

Expert Systems, Volume 43, Issue 7, July 2026.
ABSTRACT In the digital era, the internet and social media have transformed communication but have also facilitated the spread of hate speech and disinformation, leading to radicalization, polarisation and toxicity. This is especially concerning for media outlets due to their significant role in shaping public discourse. This study examines the topics,

A Comparative Aerodynamic study of Nonplanar Wings

International Journal of Aviation, Aeronautics, and Aerospace, 2019
In this work four nonplanar wing configurations were studied using the vortex-lattice method: the wing-winglet, the C-wing, the biplane, and the box wing.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
