The split-elbow index: A biomarker of the split elbow sign in ALS
Clinical Neurophysiology Practice, 2022 Objective: The split elbow sign is a clinical feature of amyotrophic lateral sclerosis (ALS), characterised by preferential weakness of biceps brachii muscle compared to triceps.

Split hand syndrome and the split hand index in ALS patients [PDF]
Romanian Journal of Neurology, 2018 Our objective has been a review of the recent data available in reference to the split hand clinical sign in amyotrophic lateral sclerosis (ALS) and its novel electrophysiological counterpart the split hand index (SHI).

Tunable split-ring resonators for nonlinear negative-index metamaterials [PDF]
Optics Express, 2006 We study experimentally the dynamic tunability and self-induced nonlinearity of split-ring resonators incorporating variable capacitance diodes. We demonstrate that the eigenfrequencies of the resonators can be tuned over a wide frequency range, and ...

Inconsistency was more prevalent than reported: an empirical study of 57 networks with multiple treatments using the node-splitting approach and a novel interpretation index [PDF]
Systematic ReviewsBackground Inconsistency has been reported to be ubiquitous in network meta-analysis. However, this evidence is based on statistical tests for inconsistency with well-documented power limitations.

Index Theory of Chiral Unitaries and Split-Step Quantum Walks [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2023 Building from work by Cedzich et al. and Suzuki et al., we consider topological and index-theoretic properties of chiral unitaries, which are an abstraction of the time evolution of a chiral-symmetric self-adjoint operator. Split-step quantum walks provide a rich class of examples.

Non-onsite symmetries and quantum teleportation in split-index matrix product states [PDF]
QuantumWe describe a class of spin chains with new physical and computational properties. On the physical side, the spin chains give examples of symmetry-protected topological phases that are defined by non-onsite symmetries, i.e., symmetries that are not a ...

Unbiased split selection for classification trees based on the Gini Index [PDF]
, 2006 The Gini gain is one of the most common variable selection criteria in machine learning. We derive the exact distribution of the maximally selected Gini gain in the context of binary classification using continuous predictors by means of a combinatorial ...

The Index and Split Forms of Linear Differential-Algebraic Equations
Известия Иркутского государственного университета: Серия "Математика", 2019 We consider linear systems of ordinary differential equations (ODE) with rectangular matrices of coefficients, including the case when the matrix before the derivative of the desired vector function is not full rank for all argument values from the ...

Combined Thermal Index Development for Urban Heat Island Detection in Area of Split, Croatia [PDF]
LandUrban heat islands (UHIs) are a phenomenon of temperature rising within urban areas relative to their rural counterparts. UHIs are becoming an increasingly common problem in large cities, which appear due to excessive urbanization and reductions in ...
