Euclid preparation. XCII. Controlling angular systematics in the Euclid spectroscopic galaxy sample [PDF]

open access: yesAstronomy & Astrophysics
We present the strategy used to identify and mitigate potential sources of angular systematics in the spectroscopic galaxy survey, and we quantify their impact on galaxy clustering measurements and cosmological parameter estimation. We first surveyed the

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Computing in matrix groups without memory [PDF]

open access: yes, 2013
Funding: UK Engineering and Physical Sciences Research Council award EP/K033956/1Memoryless computation is a novel means of computing any function of a set of registers by updating one register at a time while using no memory.

The Power of the Lorentz Quantum Computer

open access: yesEntropy
We analyze the power of the recently proposed Lorentz quantum computer (LQC), a theoretical model leveraging hyperbolic bits (hybits) governed by complex Lorentz transformations.

Towards a Computational Theory of Semantic Memory [PDF]

open access: yes, 1984
Memory is one of the most important functions of the human brain, yet its understanding — why and how it does what it does — has so far eluded us. Research in memory has been a frustrating task not least because of the intimate familiarity with what we are trying to understand, and partly also because the human cognitive system has developed as an ...

Euclid preparation. LXX. Forecasting detection limits for intracluster light in the Euclid Wide Survey [PDF]

open access: yesAstronomy & Astrophysics
The intracluster light (ICL) permeating galaxy clusters is a tracer of the cluster assembly history and potentially a tracer of their dark matter structure.

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

open access: yesAnnals 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.

Approximation resistance on satisfiable instances for predicates with few accepting inputs

open access: yes, 2014
For every integer k ≥ 3, we prove that there is a predicate P on k Boolean variables with (Formula Presented) accepting assignments that is approximation resistant even on satisfiable instances. That is, given a satisfiable CSP instance with constraint P,

Modular Semantics for Object-Oriented Models [PDF]

open access: yes, 1998
This paper describes a formal, modular approach to the semantics of object-oriented models. These models are expressed in the UML notation augmented with the Object Constraint language (OCL), which provides a precise textual language for expressing ...

P Systems with Evolutional Communication and Division Rules

open access: yesAxioms, 2021
A widely studied field in the framework of membrane computing is computational complexity theory. While some types of P systems are only capable of efficiently solving problems from the class P, adding one or more syntactic or semantic ingredients to ...
