Clustering of Mass and Galaxies [PDF]

, 2001
These lectures cover various aspects of the statistical description of cosmological density fields. Observationally, this consists of the point process defined by galaxies, and the challenge is to relate this to the continuous density field generated by gravitational instability in dark matter.

Similarity Assessment of the Engineering Concepts: Decision‐Making Support and Metrics

Systems Engineering, EarlyView.
ABSTRACT The new product development (NPD) process is a systematic approach to bring new products and innovations to market. Nowadays, this process is affected by a number of influencing factors associated with the fast‐paced technological changes. One of those factors is the distributed design nature of product development activities: team members are

Machine learning approach of multi‐RAT selection for travelling users in 5G NSA networks

IET Networks, EarlyView.
The authors present RAT selection algorithm for efficient resource allocation for public bus travelling user(s), utilising live data from multiple 5G NSA base stations. Models of the supervised machine learning algorithms: SVM, DNN and XGBoost were deployed for implementation to predict or select the appropriate RAT between 4G and 5G RATs.

A Comparison Between the Half-Light Radii, Luminosities, and UBV Colors of Globular Clusters in M31 and the Galaxy

, 2010
The Milky Way System and the Andromeda galaxy experienced radically different evolutionary histories. Nevertheless, it is found that these two galaxies ended up with globular cluster systems in which individual clusters have indistinguishable ...

Gut Mycobiota of Three Rhinopithecus Species Provide New Insights Into the Association Between Diet and Environment

Integrative Zoology, EarlyView.
This study revealed the basic structures of gut mycobiota of three wild Rhinopithecus species. The gut mycobiota of Rhinopithecus showed close connection with their feeding habits, and there were associations between gut mycobiota and the host's living environments.

The evolution of galaxy clustering [PDF]

Monthly Notices of the Royal Astronomical Society, 1997
This paper investigates whether nonlinear gravitational instability can account for the clustering of galaxies on large and small scales, and for the evolution of clustering with epoch. No CDM-like spectrum is consistent with the shape of the observed nonlinear spectrum. Unbiased low-density models greatly overpredict the small-scale correlations; high-

Age‐Associated Decline in Autophagy Pathways in the Retinal Pigment Epithelium and Protective Effects of Topical Trehalose in Light‐Induced Outer Retinal Degeneration in Mice

Aging Cell, EarlyView.
Transcriptomic analyses reveal an age‐related decline in autophagy pathways in RPE/choroid. These pathways remain unchanged in early AMD but become bidirectionally dysregulated in later stages, along with increased RPE loss. Pre‐treatment with trehalose eyedrops enhances RPE autophagy flux and prevents light‐induced outer retinal degeneration in mice ...

(2R,6R)‐hydroxynorketamine prevents opioid abstinence‐related negative affect and stress‐induced reinstatement in mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Opioid use disorder (OUD) is a pressing public health concern marked by frequent relapse during periods of abstinence, perpetuated by negative affective states. Classical antidepressants or the currently prescribed opioid pharmacotherapies have limited efficacy to reverse the negative affect or prevent relapse ...

Towards Scaling‐Invariant Projections for Data Visualization

Computer Graphics Forum, EarlyView.
Abstract Finding projections of multidimensional data domains to the 2D screen space is a well‐known problem. Multidimensional data often comes with the property that the dimensions are measured in different physical units, which renders the ratio between dimensions, i.e., their scale, arbitrary.

Gaze‐Aware Visualisation: Design Considerations and Research Agenda

Computer Graphics Forum, EarlyView.
We assemble a design framework for gaze‐aware visualisations along four axes—measurable data, inferable data, opportunities for support, and limiting factors to beware—and distil visualisation research challenges that preclude such systems. We show how our framework can be applied in practice to consider how eye‐tracking may benefit visualisation ...
