High-efficient isolated DC/DC converters with a high-efficiency synchronous reluctance generator (SRG) are the ultimate solutions in DC microgrid systems. The design and modeling of isolated DC/DC converters with the performance of SRG are carried out. Reactive and active powers are used as PWM control variables on the generator side. Further, the flux estimator is used. Three-phase pulse width modulation (PWM) rectifier is used by applying space vector modulation (SVM) with a constant switching frequency for direct power control. Further, the paper also includes the experimental validation of the results.

    The paper also proposes that highly efficient power converters and synchronous reluctance generators are required to achieve high performance for hybrid renewable energy systems applications.

the study highlights that LTV is more effective than NTV and ETV against M^pro mutants, making it a promising candidate for treating drug-resistant strains of SARS-CoV-2.

The team conducted the first extensive study of automated issue classification on 9 state-of-the-art issue classification approaches.

A novel discovery in the field of pancreatic cancer treatment has been unveiled, revealing the epigenetic silencing of BEND4 as a potential synthetic lethal marker for enhancing the efficacy of ATM inhibitors in pancreatic cancer treatment. This innovative research provides a groundbreaking approach to targeting a tumor suppressor gene, BEND4, which is frequently methylated and silenced in pancreatic cancer. The study delves into the role of BEND4 in DNA damage repair and its potential as a therapeutic marker when combined with ATM inhibitor treatment.

Hong Kong’s unique marine environment, with its rich ecosystems, provides vital habitats and food sources for various marine species. However, rapid urbanisation and population growth pose significant challenges, including marine pollution, overfishing and climate change. A research team from the Department of Food Science and Nutrition (FSN) at The Hong Kong Polytechnic University (PolyU) is actively addressing these sustainability challenges. Their focus is on innovative marine pollution monitoring technologies and sustainable seafood research, which includes assessing the impacts of microplastics on marine ecosystems and human health, and restoring pearl oyster reefs, in alignment with the United Nations Sustainable Development Goals 2, 3 and 14.

BGI Genomics and partners have published a transformative study in Nature Communications that links genetic differences in GISTs to tailored treatment strategies. The discovery of YLPM1 as a tumor suppressor gene marks a significant step in precision oncology.

An advanced aqueous battery design incorporating photothermal technology enables rapid self-heating, making it well-suited for low-temperature environments. The battery uses photothermal current collectors to convert sunlight into heat, which is efficiently distributed throughout the system by high-conductivity suspension electrodes. This design mitigates common cold-climate challenges such as electrolyte freezing and slow ion transfer, ensuring stable performance in sub-zero conditions.
