A New User Dependent Iris Recognition System Based on an Area Preserving Pointwise Level Set Segmentation Approach

open access: yesEURASIP Journal on Advances in Signal Processing, 2009
This paper presents a new user dependent approach in iris recognition systems. In the proposed method, consistent bits of iris code are calculated, based on the user specifications, using the user's mask.

Airway Involvement in Conradi–Hünermann–Happle Syndrome: A Novel Clinical Manifestation

open access: yesThe Laryngoscope, EarlyView.
We report the first documented case of airway involvement in Conradi–Hünermann–Happle syndrome (CDPX2), an X‐linked dominant form of chondrodysplasia punctata caused by pathogenic variants in EBP. A 2‐month‐old female with genetically confirmed CDPX2 developed severe subglottic stenosis and persistent respiratory distress requiring CPAP; cross ...

Fast and reliable iris segmentation algorithm

open access: yesIET Image Processing, 2013
Design a fast and reliable iris segmentation algorithm for less constrained iris images is essential to build a robust iris recognition system. Daugman's integrodifferential operator (IDO) is one of powerful iris segmentation mechanisms, but in contrast consumes a large portion of the computational time for localising the rough position of the iris ...

Smile Asymmetry and Eyelid Closure Following Temporalis Muscle Transfer for Facial Reanimation: A Systematic Review and Meta‐Analysis

open access: yesThe Laryngoscope, EarlyView.
This systematic review and meta‐analysis of 53 studies and 1354 patients evaluates the outcomes of temporalis muscle transfer in facial nerve paralysis. Our results show that temporalis muscle transfer can restore smile asymmetry, oral commissure movement, and eyelid closure—findings that are translated to clinician‐rated assessments.

Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

Increased Serum Neurofilament Light Chain Levels in Parkinson's Disease Patients Carrying the p.A53T SNCA Mutation: Data from the Parkinson's Progression Markers Initiative Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Serum neurofilament light chain (NfL) levels, a marker of axonal damage, are generally elevated in neurodegenerative conditions, but results in idiopathic Parkinson's disease (iPD) have been inconsistent. The p.A53T SNCA mutation usually leads to a severe form of PD.

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

open access: yesNordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.
