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.

Application of Electromagnetic Field Tensors in Special Relativity Theory [PDF]
, 2016 Maxwell’s Field Equations (MFE’s) for the propagation of electromagnetic waves were found to be invariant under Lorentz transformation (LT) and could be derived using assumptions different from what Einstein used.

Acceleration sensors, and inertia and gravity forces
Технологія та конструювання в електронній апаратурі, 2007 Using acceleration sensors as an example, inertia forces are examined, and an analogy is drawn between the phenomena of inertia in mechanics and self‑induction in electrical engineering.

Are Rindler Quanta Real? Inequivalent Particle Concepts in Quantum Field Theory [PDF]
, 2000 Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of what a particle is. However, there has been relatively little discussion of the threat to the "reality" of particles posed by the possibility of ...

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

Maxwell's original electromagnetic theory (1865) was formulated later in quaternion algebra (Treatise 1873), and then set aside in favour of the vector reformulation of Heaviside and Gibbs. This paper revisits quaternion algebra as an active cross-disciplinary tool: applying the same quaternion-nabla operator to the appropriate physical quaternion ...

Lorentz invariant field theory on κ-Minkowski space [PDF]
, 2010 It is by now well established that the momentum space associated with the non-commutative κ-Minkowski space is a submanifold of de Sitter space. It has been noted recently that field theories built on such momentum space suffer from a subtle form of ...

Utility of the APE2 Score as a Diagnostic Tool for Autoimmune Encephalitis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To retrospectively evaluate the diagnostic performance of the Antibody Prevalence in Epilepsy and Encephalopathy (APE2) score relative to clinician‐adjudicated autoimmune encephalitis (AE) and the Graus criteria in a tertiary neuroimmunology referral cohort, including antibody‐negative AE.

Arthritis Care &Research, EarlyView.Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.
