Understanding the Phenotypic Heterogeneity Within the Sporadic Creutzfeldt–Jakob Disease MV1 Subtype

Neuropathology and Applied Neurobiology, Volume 52, Issue 3, June 2026.
We present the clinical, pathological and prion biophysical features of three atypical cases of the MV1 subtype of sporadic Creutzfeldt–Jakob disease (sCJD). We propose that these heterozygous cases exist on a spectrum ranging from MM1‐like to VV1‐like phenotypes and recommend that subtyping be performed at pH 6.9 to avoid missing atypical or mixed ...

A New Similarity Function for Generalized Trapezoidal Fuzzy Numbers [PDF]

, 2013
Numerous authors have proposed functions to quantify the degree of similarity between two fuzzy numbers using various descriptive parameters, such as the geometric distance, the distance between the centers of gravity or the perimeter. However, these similarity functions have drawback for specific situations.

Impact of Variations in Membership Functions on the Performance of ANFIS for Nonlinear Systems as a Benchmark

Engineering Reports, Volume 8, Issue 5, May 2026.
The graphical abstract illustrates how different membership functions influence the performance of ANFIS when applied to nonlinear system control, demonstrating clear variations in overshoot, settling behavior, and training accuracy across the four MF types.

Motion‐ and Field‐Robust Mesoscopic Whole‐Brain T2*$$ {T}_2^{\ast } $$‐Weighted Imaging at 7 and 11.7 T Using Servo Navigation

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2658-2670, May 2026.
ABSTRACT Purpose To mitigate artifacts related to motion and field changes in high‐resolution T2*$$ {T}_2^{\ast } $$‐weighted human brain imaging using servo navigation at ultra‐high fields up to 11.7 T. Methods MR‐based servo navigators were integrated into a segmented 3D‐EPI sequence to allow for prospective correction of involuntary head motion and ...
