Efficient waveguide power combiners at mm‐wave frequencies

IET Microwaves, Antennas & Propagation, 2023
In this study, an efficient power combiner for mm‐wave frequency transmitters is investigated. The combiner is based on a parallel plate waveguide (PPW) excited with multiple parallel feeds.

Unraveling 4‐Phenylbutyrate's Therapeutic Role in SLC6A1 Disorders: Pharmacochaperoning Over HDAC Inhibition

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Variants in SLC6A1, encoding the GABA transporter 1 (GAT‐1), cause epilepsy, autism spectrum disorder, and developmental delay via loss of GABA uptake, impaired trafficking, and ER retention. We previously found that 4‐Phenylbutyrate (PBA), an FDA‐approved drug, restores GABA uptake and reduces seizures in SLC6A1‐related disorders ...

Compact diplexer with high isolation based on mixed‐mode triangular substrate integrated waveguide cavities

Electronics Letters, 2023
A novel compact diplexer based on mixed‐mode isosceles right triangular (IRT) substrate integrated waveguide (SIW) cavities is presented. A dual‐mode IRT SIW junction cavity is direct‐coupled with two single‐mode IRT SIW cavities for lower and upper ...

White Matter Microstructural Abnormalities in Neonatal Onset Genetic Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Recent evidence indicates that epilepsy is associated with abnormal white matter. If seizures alter white matter, then the impact upon network function, epileptogenesis, and cognition could be pronounced in neonates undergoing rapid developmental myelination. Neonates with epilepsy due to nonstructural genetic causes provide a unique

Design methodology for high‐performance low‐cost microstrip termination load for mmWave applications

Electronics Letters, 2023
Millimetre wave (mmWave) has been a popular research topic in recent years. Termination loads are useful for RF components and integrated circuits. Commercially available terminators are expensive and not easily applicable for integration to MMICs.

Subclinical Optic Nerve Involvement in Radiologically Isolated Syndrome: Multimodal Detection and Diagnostic Impact

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We aimed to determine the frequency of subclinical optic nerve (ON) lesions using MRI, optical coherence tomography (OCT), and visual evoked potentials (VEP) in radiologically isolated syndrome (RIS), and to assess their diagnostic and prognostic significance.

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Wideband end‐fire circularly polarised complementary source antenna for millimetre‐wave applications

IET Microwaves, Antennas & Propagation, 2021
A millimetre‐wave end‐fire circularly polarised (CP) complementary source antenna is proposed. Circular polarisation is obtained by combining a quarter‐wave shorted patch and a planar electric dipole. A direct‐feeding method based on the use of substrate

Integration of Serum Neurofilament Light Chain and Cortical Dysfunction Improves Diagnostic Accuracy in ALS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether integration of serum neurofilament light chain (NfL) and cortical dysfunction improves diagnostic accuracy in amyotrophic lateral sclerosis (ALS) when applied alongside the Gold Coast criteria (GCC). Methods In this prospective study, 148 participants with suspected ALS were recruited (101 ALS and 47 with ALS ...

Regeneration of sand waves after dredging [PDF]

, 2002
Sand waves are large bed waves on the seabed, being a few metres high and lying hundreds of metres apart. In some cases, these sand waves occur in navigation channels.
