Star cluster ecology IVa: Dissection of an open star cluster---photometry [PDF]

, 2000
The evolution of star clusters is studied using N-body simulations in which the evolution of single stars and binaries are taken self-consistently into account.

Cluster and Double Star observations of dipolarization [PDF]

Annales Geophysicae, 2005
We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC-1) were located in the same local time sector: 7 August 2004, 18:00-24:00 UT, during a disturbed southward/northward IMF interval, and 14

The Membership and Distance of the Open Cluster Collinder 419

, 2010
The young open cluster Collinder 419 surrounds the massive O star, HD 193322, that is itself a remarkable multiple star system containing at least four components.

Dissolving star cluster candidates [PDF]

, 2000
We present a list of 34 neglected entries from star cluster catalogues located at relatively high galactic latitudes ($|b| >$ 15$^{\circ}$) which appear to be candidate late stages of star cluster dynamical evolution. Although underpopulated with respect

Joint Power Allocation Algorithm for UAV-Borne Simultaneous Transmitting and Reflecting Reconfigurable Intelligent Surface-Assisted Non-Orthogonal Multiple Access System

IEEE Access, 2023
As a novel technology, simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) provides users with full spatial coverage communication by modulating reflected and refracted signals.

The effect of the dynamical state of clusters on gas expulsion and infant mortality [PDF]

, 2008
The star formation efficiency (SFE) of a star cluster is thought to be the critical factor in determining if the cluster can survive for a significant (>50 Myr) time.

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

JWST Observations of Starbursts: Massive Star Clusters in the Central Starburst of M82

The Astrophysical Journal Letters
We present a near-infrared (NIR) candidate star cluster catalog for the central kiloparsec of M82 based on new JWST NIRCam images. We identify star cluster candidates using the F250M filter, finding 1357 star cluster candidates with stellar masses >10 ^4

The influence of stellar-dynamical ejections and collisions on the relation between the maximum-star and star-cluster-mass

, 2012
We perform the largest currently available set of direct N-body calculations of young star cluster models to study the dynamical influence, especially through the ejections of the most massive star in the cluster, on the current relation between the ...

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.
