Learning to Divide and Conquer for Online Multi-Target Tracking [PDF]

open access: yes, 2015
Online Multiple Target Tracking (MTT) is often addressed within the tracking-by-detection paradigm. Detections are previously extracted independently in each frame and then objects trajectories are built by maximizing specifically designed coherence ...

The Physics of Crystallization from Globular Cluster White Dwarf Stars in NGC 6397 [PDF]

open access: yes, 2009
We explore the physics of crystallization in the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from proper motion cleaned Hubble Space Telescope photometry of the globular cluster NGC 6397.

A new approach to measuring absolute pitch on a psychometric theory of isolated pitch perception: Is it disentangling specific groups or capturing a continuous ability?

open access: yesPLoS ONE, 2021
Absolute Pitch (AP) is commonly defined as a rare ability that allows an individual to identify any pitch by name. Most researchers use classificatory tests for AP which tracks the number of isolated correct answers.

The Storm-Track Response to Idealized SST Perturbations in an Aquaplanet GCM [PDF]

open access: yes, 2008
The tropospheric response to midlatitude SST anomalies has been investigated through a series of aquaplanet simulations using a high-resolution version of the Hadley Centre atmosphere model (HadAM3) under perpetual equinox conditions.

Dynamics of latent HIV under clonal expansion.

open access: yesPLoS Pathogens, 2021
The HIV latent reservoir exhibits slow decay on antiretroviral therapy (ART), impacted by homeostatic proliferation and activation. How these processes contribute to the total dynamic while also producing the observed profile of sampled latent clone ...

SHI induced nano track polymer filters and characterization [PDF]

open access: yes, 2009
Swift heavy ion irradiation produces damage in polymers in the form of latent tracks. Latent tracks can be enlarged by etching it in a suitable etchant and thus nuclear track etch membrane can be formed for gas permeation / purification in particular for

Latent Tracks in Ion-Irradiated LiTaO3 Crystals: Damage Morphology Characterization and Thermal Spike Analysis

open access: yesCrystals, 2020
Systematic research on the response of crystal materials to the deposition of irradiation energy to electrons and atomic nuclei has attracted considerable attention since it is fundamental to understanding the behavior of various materials in natural and

Analysis of latent tracks for MeV protons in CR-39 [PDF]

open access: yesJournal of Applied Physics, 2007
For protons of energy up to a few MeV, the temporal evolution of etched latent tracks in CR-39 nuclear track detector has been numerically modeled by assuming that the electronic energy loss of the protons governs the latent track formation. The technique is applied in order to obtain the energy spectrum of high intensity laser driven proton beams ...

Moist available potential energy of the mean state of the atmosphere and the thermodynamic potential for warm conveyor belts and convection [PDF]

open access: yesWeather and Climate Dynamics, 2023
Much of our understanding of atmospheric circulation comes from relationships between aspects of the circulation and the mean state of the atmosphere. In particular, the concept of mean available potential energy (MAPE) has been used previously to relate

Downstream Self-Destruction of Storm Tracks [PDF]

open access: yes, 2011
The Northern Hemisphere storm tracks have maximum intensity over the Pacific and Atlantic basins; their intensity is reduced over the continents downstream.
