European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

A Transient Damping Improvement Strategy for Enhancing Grid-Connected Active Power Response Performance of VSG

open access: yesEnergies
The given power and grid frequency disturbances can cause transient oscillations and steady-state deviations in the output power of a virtual synchronous generator (VSG), which can be effectively addressed by adding transient damping.

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

Small-Signal Modeling of pHEMTs and Analysis of their Microwave Performance [PDF]

open access: yesJournal of Engineering and Applied Sciences, 2010
Accurate extraction of the small-signal equivalent circuit of GaAs microwave Field Effect Transistors (GaAs FET) is crucial for efficient design of microwave analog circuits such as Low Noise Amplifiers (LNAs). This study proposed an improved direct analytical extraction procedure. Its efficiency was demonstrated through the characterisation of two 1μm

Quasi-Electromechanical Oscillation Analysis of VSG Grid-Connected System Based on Small-Signal Model

open access: yesIEEE Access
VSG is a pivotal control strategy for GFM, designed to enhance the damping and inertia of power systems, thereby bolstering their stability. Despite its benefits, VSG can induce a QEO due to dynamic interactions between the GFM and the power system. This

Accurate Small-Signal Modeling of FD-SOI MOSFETs [PDF]

open access: yesIEICE Transactions on Electronics, 2006
A new small-signal model for fully depleted silicon-on-insulator (FD-SOI) MOSFETs operating at RF frequencies is presented. The model accounts for the non-quasi-static effect by determining model parameters using a curve fitting procedure to reproduce the frequency response of FD-SOI MOSFETs.

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.
