Comparison of Iterative Reconstruction algorithms on PET-CT devices : Iterative CT -reconstruction

, 2023
Medical imaging utilizes radiation to examine a patient’s anatomy and internal structures. One imaging method is CT imaging, where an X-ray tube and detectors on the opposite side rotate around the patient to get images describing the patient’s internal structures in 3-D.

Continual Learning for Multimodal Data Fusion of a Soft Gripper

Advanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Rupestonic Acid of Artemisia Rupestris L. Extract Treats Pulmonary Fibrosis in COPD by Targeting TGF‐β1

Advanced Science, EarlyView.
RA of EEAR inhibits TGF‐β1 ubiquitination and changes conformation by target binding TGF‐β1, regulating TGF‐β1/Smad2/3 signaling pathway. Thus it down‐regulated downstream protein expression, inhibited EMT and collagen deposition of ECM, in order to EEAR preventing PF in COPD.

Integrated Transcriptomics Reveals Evolutionary Trajectories and Cell Density‐Dependent Mechanisms in Aldosterone‐Producing Adenomas

Advanced Science, EarlyView.
Aldosterone‐producing adenomas (APAs) develop via two distinct paths: directly from adrenal zona glomerulosa (zG) cells, or stepwise from zG cells through aldosterone‐producing micronodules (APMs) before progressing to APAs. Advanced single‐cell and spatial analyses identified distinct cell states linked to oxidative stress and cell–cell interactions ...
