Research on Positioning Control Strategy for a Hydraulic Support Pushing System Based on Iterative Learning

Actuators, 2023
At present, the positioning control of the hydraulic support pushing systems in fully mechanized mining faces uses an electrohydraulic directional valve as the control component, while the current research mainly focuses on servo valves, proportional ...

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

Pediatric 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 ...

Practical loop-shaping strategy for ensuring robust performance in MISO systems

Journal of Advanced Mechanical Design, Systems, and Manufacturing
This paper presents a loop-shaping methodology for enhancing robust performance in Multi-Input-Single-Output (MISO) control systems. The core of our approach lies in the Robust Bode (RBode) plot, a graphical tool that extends conventional Bode analysis ...

Analysis of open-loop characteristics on SISO sampled-data positioning control system

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
In the sampled-data positioning control system of mechatronic products, it is hard to analyze the effect of mechanical resonances above the Nyquist frequency after the control systems were assembled.

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

Central Nervous System Neuroblastoma, FOXR2‐Activated: A Pooled Analysis of Published Clinical Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) neuroblastoma, FOXR2‐activated, is a recently recognized entity in the WHO CNS5 classification, defined by activation of the FOXR2 transcription factor and unique histopathological features. This review synthesizes available literature and pooled clinical data, providing insight into demographics ...
