Calculation of losses in 2-D photonic crystal membrane waveguides using the 3-D FDTD method [PDF]

, 2004
The three-dimensional finite-difference time-domain method is used to obtain loss per unit length in a two-dimensional photonic crystal membrane waveguide by simulating three different length guides. Results are shown for propagation both above and below

A Machine Learning Perspective on the Brønsted–Evans–Polanyi Relation in Water‐Gas Shift Catalysis on MXenes

Advanced Intelligent Discovery, EarlyView.
Machine learning predicts activation energies for key steps in the water‐gas shift reaction on 92 MXenes. Random Forest is identified as the most accurate model. Reaction energy and reactant LogP emerge as key descriptors. The approach provides a predictive framework for catalyst design, grounded in density functional theory data and validated through ...

Genetic characterisation of Germanata Veneta and Mignon local duck breeds (Anas platyrhynchos) using whole-genome sequencing

Italian Journal of Animal Science
This study investigated the genetic diversity and conservation status of two endangered Italian duck breeds: Germanata Veneta (GER, n = 50) and Mignon (MIG, n = 50). The DNA was extracted from blood and analysed through whole-genome sequencing.

Remote Language Assessment in School‐Age Children With Phelan–McDermid Syndrome and Genotype–Phenotype Correlation

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT People with Phelan–McDermid syndrome (PMS) have reduced speech and language abilities, yet little research has profiled the communication abilities in this population. The purpose of this study was threefold: identifying the language and communication profiles of school‐aged children with PMS, identifying genetic contributions to language and ...

Noonan Syndrome Spectrum Disorders Predispose to Systemic Lupus Erythematosus: Case Report and Critical Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are clinically overlapping neurodevelopmental syndromes resulting from germline mutations in genes involved in the rat sarcoma/mitogen‐activated protein kinases (RAS/MAPK) pathway. Historically, RASopathies have been described by clinical phenotypes, such as Noonan syndrome and Neurofibromatosis type I.

Low-optical-loss, low-resistance Ag/Ge based ohmic contacts to n-type InP for membrane based waveguide devices [PDF]

, 2015
We present the development of Ag/Ge based ohmic contacts to n-type InP with both low contact resistances and relatively low optical losses. A specific contact resistance as low as 1.5×10-6 O cm2 is achieved by optimizing the Ge layer thickness and ...

Expanding the Genotype–Phenotype Correlation of Marden–Walker Syndrome due to PIEZO2 Gene Variants: A Case Report From Brazil

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Marden–Walker syndrome (MWS; OMIM 248700) is an extremely rare congenital disorder characterized by multiple joint contractures, craniofacial dysmorphism, neurological abnormalities, and multisystem involvement. Although historically diagnosed on clinical grounds, only a few cases have been molecularly confirmed.

Cytosolic Phosphoenoylpyruvate Carboxykinase Deficiency: Clinical, Biochemical, and Genetic Features of Five Non‐Finnish Patients

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cytosolic phosphoenoylpyruvate carboxykinase (PEPCK‐C) is an essential, rate‐limiting enzyme in the gluconeogenesis pathway. PEPCK‐C deficiency presents with hypoglycaemia, hyperlactataemia and hepatopathy, and was first reported in association with bi‐allelic PCK1 variants in 2014.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...
