Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Structures, Structures, and Structures

Angewandte Chemie International Edition in English, 1992
For quantum chemical statements about the stabilities of molecules which serve as incentives for the synthesis of new compounds, a structure determined by calculations according to the state of the art must be identified as corresponding to a minimum on the energy hypersurface. That kinetics must also not be disregarded, is the contribution of Pople et

Structure, Structural, Structuralism

Diogenes, 1969
Unlike positivism, which took the form of a protest by the individual against the canonization of the general, and unlike existentialism, which expressed a revolt of the concrete against abstraction erected into a dogma—structuralism is an ideology of capitulation to the bureaucratic and technocratic supremacy of means over ends and of society over ...

Structuralism Without Structures

Philosophia Mathematica, 1996
Abstract Recent technical developments in the logic of nominalism make it possible to improve and extend significantly the approach to mathematics developed in Mathematics without Numbers. After reviewing the intuitive ideas behind structuralism in general, the modal-structuralist approach as potentially class-free is contrasted broadly ...

The structure of “data structures”

Proceedings of the ACM '81 conference on - ACM 81, 1981
A data structure is defined to be a 4-tuple D, F, S, A>. D and F are Domain and Function definitions which define the externally observable behavior; S and A are a Storage Structure and Algorithms which implement the functions. It is shown that this definition helps organize the field of data structures for presentation to students.
