Global alignment of PPI networks
(Springer, 2021)Given multiple PPI networks from different species, the global PPI network alignment problem is that of providing a global mapping between the nodes of the networks or subnetworks within them. Functional orthology detection, ... -
Bodipy photosensitizer linked hybrid nanomaterials for photodynamic therapy
(Advanced Nanomaterials Congress, 2021)Photodynamic therapy (PDT) is an alternative clinically approved treatment method to obliterate the cancerous lesion by producing reactive oxygen species (ROS) via activated photosensitizer (PS) molecule at a certain ... -
Enhancing the stability of nanotheranostic systems
(5th International Conference on Nanomedicine and Nanotechnology, 2021)Theranostics is new term which defined as a combination of therapy and diagnosis to establish a targeted drug delivery and monitoring of treatment into a single nanosystem. The most important parameter in the theranostic ... -
Cellulose acetate encapsulated upconversion nanoparticles – a novel theranostic platform
(Materials Today Communications, 2021)Luminescent upconversion nanoparticles (UCNPs) are of great interest in a wide range of nanotechnological applications, particularly in the biomedical area like imaging and therapy but their biocompatibility and stability ... -
An alternative approach to determination of Covid‑19 personal risk index by using fuzzy logic
(Health and Techonology, 2022)COVID-19 disease is an outbreak that seriously affected the whole world, occurred in December 2019, and thus was declared a global epidemic by WHO (World Health Organization). To reduce the impact of the epidemic on humans, ... -
A hybrid movie recommender system and rating prediction model
(International Journal of Information Technology and Applied Sciences, 2021-07-01)In the current era, a rapid increase in data volume produces redundant information on the internet. This predicts the appropriate items for users a great challenge in information systems. As a result, recommender systems ... -
Prediction of VLDL cholesterol value with machine learning techniques
(Springer, 2021)Cholesterol is an oil-like substance that is found in the membranes of animal cells and also carried in blood plasma, which has some vital functions in the human body, especially in the endocrine and digestive systems. ... -
Design and experimental validation of a stress- controlled pressure sensor for wearable pulse monitoring
(2021 IEEE International Symposium on Applications of Ferroelectrics (ISAF), 2021)This paper presents a pulse sensor design scheme with adjustable preset pressure. The design consist of two PVDF layers sandwiching a PZT layer. While PZT is used to detect the pulse vibrations, PVDF layers are employed ... -
Fluorescence quenching-based bodipy-boronic acid linked viologen dual system for potential glucose sensing applications
(Sensor Review, 2022)Purpose – The purpose of this study is to develop a non-enzymatic based glucose-sensing platform composed of Bodipy-BBV dual system which can be monitored by a photodetector under the blue LED excitation. Design/method ... -
