The assessment of fatigue-related changes in stride mechanics, variability and long-range correlations in recreational and elite distance runners using foot-mounted inertial sensors
… to assess stride mechanics, variability and long-range correlations during running, as well as their relationship with fatigue and skill level. For this purpose, three separate experiments were conducted. As a first step, it was established whether a simple hardware setup consisting of a …

Localization and spreading of matter waves in disordered potentials
… characterized by the presence of both short and long range correlations. We study the localization properties of the model and highlight the role played by short and long range correlations in the determination of those properties. In particular we show that when short-range correlations are …

Analysis of polymeric extractives of Western Juniper (Juniperus occidentalis) heartwood
… polymeric material which reveals three long-range correlations. A long range labelled carbonyl correlation at around δ = 6.00 ppm corresponding to α-proton of β-O-4 type ether structures which is comparable to similar correlations found in lignins. The two other long-range correlations …

Flow of [phi] mesons in pPb collisions at the LHC with the CMS detector
Measurements of two-particle angular correlations between unidentified charged particles and [phi]-mesons are shown over a wide pseudorapidity range ([delta] [eta] < 2) in pPb collisions. The data, collected during 2013 pPb run at a nucleon-nucleon center-ofmass energy of 5.02 TeV with the CMS …

What can we learn from climate data? : Methods for fluctuation, time/scale and phase analysis
… climatological problems. First, the inference of long-range correlations by means of Detrended Fluctuation Analysis (DFA) is studied. It is argued that power-law scaling of the fluctuation function and thus long-memory may not be assumed a priori but have to be established. This requires to …

Techniques for identifying long-range residue correlations in the fifth binding module of LDLR
The study of correlations between residues in distal regions of a protein structure may provide insights into the mechanism of protein folding. Such long-range correlations may exist between distant residues that are conserved by evolution or physically related by motion. Two computational …

Anomalous statistical properties and fluctuations on multiple timescales
… of the effects is. Especially the property of long range temporal correlations (the Joseph effect) is discussed in detail. In measurements, they might arise from different dynamical origins or can be explained as an emerging phenomenon. A collection of different routes to the observed behavior …

Thermoluminescence in Carbonate Rocks and its Application to Stratigraphic correlation and Geologic Age Determination
… and geologic age dating. Both short- and long-range correlations have been attempted. No figures pertaining to geologic age dating by this method have been published. </p><p>Results of investigations show that, while glow curve data may be of some value, many problems must be solved if the …

Approaching the Three-Dimensional Organization of the Human Genome
… chromosomes revealed fine-structured positive long-range correlations due to codon, nucleosomal or block organization of the genomes, allowing classification and tree construction. By construction and expression of fusionproteins from the histones H1, H2A, H2B, H3, H4 and mH2A1.2 with the …

2-d Di-hadron Correlations at √sN N = 2.76 TeV using the ALICE experiment
… The study of two-dimensional two-particle correlations of emitted charged par- ticles carries valuable time integrated information of the dynamical QCD medium. Long-range correlations between particles in angular and momentum space generally can be attributed to collective behavior, which …

Molecular simulations of surfactants and silanes: Self-assembly in solutions and on surfaces, and friction between monolayers
… between the surfactant head groups as short-range or long-range. This work resolves this discrepancy successfully by performing a series of simulations of various structural and interaction models of surfactants. Simulations show that a realistic surfactant aggregation requires an excluded …

Estimating scale dependence of saturated hydraulic conductivity in soils

An Exploration of Bonding in V_1−x Mo_x O_2 (x ≤ 0.53) and Other Compounds
… that strong metal--metal bonding enhances short-range correlations in the rutile phase while suppressing long-range correlations in the low-temperature phases, which is also accompanied by the suppression of the transition temperature and magnitude of the lattice anomaly. Together, these findings …

Disorder at first-order classical and quantum phase transitions

Spectra at speed: neural force fields for IR spectroscopy in ionic liquids
… dynamics (MD) can address larger systems and longer simulations but often misrepresents vibrational mode ordering and intensities. Machine learning (ML)–based force fields offer a promising alternative, delivering both accuracy and efficiency. Yet most are trained on isolated molecules, …

Dynamical large deviations and phase separation in systems of interacting particles
