Photon-Counting CT Effects on Sensitivity for Liver Lesion Detection: A Reader Study Using Virtual Imaging.

Background Detection of hepatic metastases at CT is a daily task in radiology departments that influences medical and surgical treatment strategies for oncology patients. Purpose To compare simulated photon-counting CT (PCCT) with energy-integrating detector (EID) CT for the detection of small liver lesions. Materials and Methods In this reader study (July to December 2023), a virtual imaging framework was used with 50 anthropomorphic phantoms and 183 generated liver lesions (one to six lesions per phantom, 0.

An experimental and modelling approach to proclaim sustainable machining using avocado oil-based nano-cutting fluids.

Higher-end science and technology facilitate the human community with a sophisticated life despite it curses by abundant pollution. The alarming demand for sustainability pressurizes the manufacturing sector to ensure sustainable manufacturing. Since Molybdenum di sulfide (MoS) and avocado oil are known solid and liquid lubricants respectively, hence, it is a worthwhile attempt to implement the bio-based degradable avocado oil enriched with nano Molybdenum di sulfide (nMoS) particles as a potential machining fluid for CNC-end milling.

Encapsulation of Moringa oleifera aqueous extract in silver chitosan metallopolymer nanocomposites for anti-cancer activity.

The growing interest in plant-derived compounds and synthesis of metallopolymer nanocomposites (MPNCs) especially silver chitosan nanocomposites (AgCS-NCs) emerges as a useful platform to encapsulate and deliver plant-based anticancer drugs. This work presents the synthesis of AgCS-NCs by using Moringa oleifera aqueous leaf extract (MOAE) and the effect of concentration of MOAE on physicochemical properties of AgCS-NCs followed by its anticancer effect on MCF-7 cell line. The results of UV-visible spectroscopy (UV-Vis) and Scanning electron microscopy (SEM) showed successful formation of AgCS-NCs.

Computational study on water based hybrid photovoltaic systems with different absorber configurations.

The current study assesses several water-based PVT system thermal absorber configurations. The thermal absorber in PVT system plays a vital role in efficiency evaluation as it lowers PV temperature and collects heat energy. The current study aims to discover and analyze advanced thermal absorber design by comparing well-received spiral circular absorbers and non-cooled PV with proposed semi-circular thermal absorbers with varying flow configurations.

Optimization of energy management in Malaysian microgrids using fuzzy logic-based EMS scheduling controller.

The microgrid (MG) faces significant security issues due to the two-way power and information flow. Integrating an Energy Management System (EMS) to balance energy supply and demand in Malaysian microgrids, this study designs a Fuzzy Logic Controller (FLC) that considers intermittent renewable sources and fluctuating demand patterns. FLC offers a flexible solution to energy scheduling effectively assessed by MATLAB/Simulink simulations.
