Generation of optical microwave signals using laser diodes with enhanced modulation response for hybrid radio/fiber systems [PDF]

, 2001
The authors present the idea of using a laser with improved modulation bandwidth to generate microwave optical signals for hybrid radio/fibre systems. External light injection has been used to enhance the frequency response of the laser and thus greatly ...

Survey of Injection-System Design [PDF]

IEEE Transactions on Nuclear Science, 1965
The general problems of injection into particle accelerators are discussed with the criteria for the choice of injection parameters emphasized. Examples are given of the injection system designed for a 200-BeV proton synchrotron.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Long wavelength VCSEL-by-VCSEL optical injection-Locking [PDF]

, 2009
VCSEL-by-VCSEL optical injection-locking to obtain high cut-off frequencies of 1.3 μm Vertical-Cavity Surface-Emitting Lasers (VCSELs) is demonstrated. A detailed physical explanation of the underlying mechanism is presented.

Knowledge injection methods in question answering

Российский технологический журнал
Objectives. Despite the recent success of large language models, which are now capable of solving a wide range of tasks, a number of practical issues remain unsolved. For example, users of systems providing question answering (QA) services may experience

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Performance of the ALS injection system [PDF]

Proceedings of International Conference on Particle Accelerators, 2002
We started commissioning the Advanced Light Source (ALS) storage ring on January 11, 1993. The stored beam reached 60 mA on March 24, 1993 and 407 mA on April 9, 1993. The fast pace of storage ring commissioning can be attributed partially to the robust injection system. We describe the operating characteristics of the ALS injection system. >

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Assessing multi-version systems through fault Injection [PDF]

, 2001
Multi-version design (MVD) has been proposed as a method for increasing the dependability of critical systems beyond current levels. However, a major obstacle to large-scale commercial usage of this approach is the lack of quantitative characterizations ...

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...
