Transcriptional profiling directs the classification of acute leukemias of ambiguous lineage into AML, B-ALL, or T-ALL. [PDF]

Hemasphere
Abstract Acute leukemia of ambiguous lineage (ALAL) is a rare, poor‐prognosis acute leukemia subtype that cannot be assigned to a single hematopoietic lineage. Although ALAL patients are typically treated with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) regimens, optimal treatment choice is hindered by their lineage ambiguity ...

Maximum Power Point Tracking Technology of Photovoltaic Array under Partial Shading Based On Adaptive Improved Differential Evolution Algorithm

Energies, 2020
In the case of partial shading conditions, there will be more than one maximum power point (MPP) in photovoltaic (PV) array. The traditional maximum power point tracking (MPPT) methods are easy to get in the local maximum power point (LMPP) and fail ...

Maximum power point tracking in partially shaded photovoltaic systems using grasshopper optimization algorithm

IET Renewable Power Generation, 2023
The P–V curve of photovoltaic (PV) arrays has several peaks under partial shading conditions (PSCs). Therefore, to extract maximum power, it is necessary to detect its global maximum power point (GMPP). The conventional maximum power point tracking (MPPT)
