CARE as a wearable derived feature linking circadian amplitude to human cognitive functions

open access: yesnpj Digital Medicine, 2023
Circadian rhythms are crucial for regulating physiological and behavioral processes. Pineal hormone melatonin is often used to measure circadian amplitude but its collection is costly and time-consuming.

Innovated Per Adult Human UNIT Method (PAHUM) vs. Error Bound PC in Food Systems

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2022
In social & economic science disciplines, the lack of strong theories is often reflected in the lack of well-accepted common metrics defined by a UNIT. PAHU Method vs.

Twistor spaces for HKT manifolds [PDF]

open access: yes, 1996
We construct the twistor space associated with an HKT manifold, that is, a hyper-K\"ahler manifold with torsion, a type of geometry that arises as the target space geometry in two-dimensional sigma models with (4,0) supersymmetry.

On the Strong Scaling of the Spectral Element Solver Nek5000 on Petascale Systems

open access: yes, 2016
The present work is targeted at performing a strong scaling study of the high-order spectral element fluid dynamics solver Nek5000. Prior studies indicated a recommendable metric for strong scalability from a theoretical viewpoint, which we test here ...

Feasibility of filter-exchange imaging (FEXI) in measuring different exchange processes in human brain

open access: yesNeuroImage, 2020
Transmembrane water exchange, including intra-to-extravascular and intra-to-extracellular ones, are potential biomarkers in the diagnosis and understanding of cancers, brain disorders, and other diseases. Filter-exchange imaging (FEXI), a special case of

Modular Invariant Regularization of String Determinants and the Serre GAGA Principle

open access: yes, 2013
Since any string theory involves a path integration on the world-sheet metric, their partition functions are volume forms on the moduli space of genus g Riemann surfaces M_g, or on its super analog.

Locally Testable Codes and Cayley Graphs [PDF]

open access: yes, 2013
We give two new characterizations of ($\F_2$-linear) locally testable error-correcting codes in terms of Cayley graphs over $\F_2^h$: \begin{enumerate} \item A locally testable code is equivalent to a Cayley graph over $\F_2^h$ whose set of generators ...

Cartan-Weyl 3-algebras and the BLG Theory II: Strong-Semisimplicity and Generalized Cartan-Weyl 3-algebras

open access: yes, 2010
One of the most important questions in the Bagger-Lambert-Gustavsson (BLG) theory of multiple M2-branes is the choice of the Lie 3-algebra. The Lie 3-algebra should be chosen such that the corresponding BLG model is unitary and admits fuzzy 3-sphere as a
