Radio spectra and polarisation properties of a bright sample of Radio-Loud Broad Absorption Line Quasars [PDF]

, 2012
The origin of broad-absorption-line quasars (BAL QSOs) is still an open issue. Accounting for ~20% of the QSO population, these objects present broad absorption lines in their optical spectra generated from outflows with velocities up to 0.2c.

Catalyst Layer Modifications for Enhanced Performance of Fluorine‐Free Proton Exchange Membrane Fuel Cells

Advanced Energy and Sustainability Research, EarlyView.
Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.

Congenital Perineal Lipoma-like Lipoblastoma

Journal of Pediatrics Review, 2020
Introduction: Adipocytic tumors and its variants are common neoplasms of adults; however, they are rarely seen in paediatric age group, too.  Lipoblastoma typically occurs in children and are diagnosed by the presence of a multivacuolated lipoblast ...

Radio spectra and polarisation properties of radio-loud Broad Absorption Line Quasars

, 2008
We present multi-frequency observations of a sample of 15 radio-emitting Broad Absorption Line Quasars (BAL QSOs), covering a spectral range between 74 MHz and 43 GHz. They display mostly convex radio spectra which typically peak at about 1-5 GHz (in the

Identification of Exhaled Volatile Organic Compounds Biomarkers for Lung Cancer Under Data‐Limited Conditions Using Data Augmentation and Multi‐View Feature Selection

Advanced Intelligent Discovery, EarlyView.
This work introduces a novel framework for identifying non‐small cell lung cancer biomarkers from hundreds of volatile organic compounds in breath, analyzed via gas chromatography‐mass spectrometry. This method integrates generative data augmentation and multi‐view feature selection, providing a stable and accurate solution for biomarker discovery in ...

Abdominal Cocoon Syndrome in a Child With Intestinal Obstruction: A Case Report and Literature Review

Journal of Pediatrics Review, 2020
Abdominal cocoon syndrome or idiopathic Sclerosing Encapsulating Peritonitis (SEP) is an extremely uncommon cause of intestinal obstruction. Its etiology is explainable through numerous theories.

Nasopharyngeal pituitary in newborn: A diagnostic dilemma

Otolaryngology Case Reports, 2019
Congenital nasopharyngeal masses are rare and usually benign. We encountered a case of a nasopharyngeal cyst with pituitary tissue in a newborn, causing severe airway obstruction. The mass was removed without complications. Considering the rarity of this

A Chandra Survey of the X-ray Properties of Broad Absorption Line Radio-Loud Quasars

, 2009
This work presents the results of a Chandra study of 21 broad absorption line (BAL) radio-loud quasars (RLQs). We conducted a Chandra snapshot survey of 12 bright BAL RLQs selected from SDSS/FIRST data and possessing a wide range of radio and CIV ...

The FIRST Bright Quasar Survey III. The South Galactic Cap [PDF]

, 2001
We present the results of an extension of the FIRST Bright Quasar Survey (FBQS) to the South Galactic cap, and to a fainter optical magnitude limit. Radio source counterparts with SERC R magnitudes brighter than 18.9 which meet the other FBQS criteria ...

Individualized Atrophy‐Based Prediction of Dementia Progression in Familial Frontotemporal Lobar Degeneration With Bayesian Linear Mixed‐Effects Modeling

Annals of Neurology, EarlyView.
Objective Age of symptom onset is highly variable in familial frontotemporal lobar degeneration (f‐FTLD). Accurate prediction of onset would inform clinical management and trial enrollment. Prior studies indicate that individualized maps of brain atrophy can predict conversion to dementia in f‐FTLD.
