Novel Physical And Biological Applications Of Carbon Ion Radiotherapy, Danushka Seneviratne, Prapannajeet Biswal, Sunil Krishnan

The Brown Foundation: Institute of Molecular Medicine

Carbon ion radiation therapy (CIRT) is a high-LET radiotherapy, which distinguishes itself from traditional low-LET radiation, such as photons and protons, through its unique physical aspects, biological attributes, and the dramatically increased damage it causes within cellular DNA. Given its distinctive characteristics, it is expected to improve the therapeutic ratio of radiation treatments and enhance treatment outcomes in traditionally radiation-resistant tumor histologies. Despite these unique properties, much remains to be understood regarding the clinical use of CIRT before its full potential can be realized. In this review, we summarize the distinct advantages of CIRT with regard to its physical and …

Faculty Research, Scholarly, and Creative Activity

This study presents the first comprehensive techno-economic assessment of wind-based green hydrogen production across Senegal, a country highly dependent on fossil fuel imports. Using a novel integrated approach combining 30 years of ERA5 reanalysis data (1993–2023), turbine performance modeling and electrolyzer comparison, it fills an important gap for renewable hydrogen development in West Africa. Wind resources were analyzed at multiple altitudes, revealing strong potential in both coastal and northeastern regions, particularly during the dry season, with higher wind speeds at higher turbine heights. Four turbines (Vestas_150, Goldwind_155, Vestas_126 and Nordex_N100) and two electrolyzer types (alkaline and PEM) were evaluated. The …

Journal of Bioresource Management

Cancer is one of the main causes of deaths in the world. Conventional cancer therapeutic approaches such as chemo- and radiotherapy have burdened the cancer patients with arduous physical and psychological challenges. Moreover, in case of onset of this disease, huge amount is required against the medications (chemotherapy and radiotherapy). It is estimated that annually, the increasing cancer disease incidence rate is alarming. In developed countries, the health support is given by the nation. Therefore, the health managements in the developed nations are over-burdened due to heavy expanses against expansive cancer therapy treatments. Interestingly, tumor treatments have undergone a comprehensive …

Comprehensive Assessment Of The Impact Of Hydrogeological Factors On The Stability Of Open-Pit Slopes, Vokhid Rakhimovich Kadirov, Khurshida Yunusovna Norova, Zavkiddin Yahyo Oglu Ravshanov, Jamol Hasankhonovich Abdumalikov

Technical science and innovation

This paper presents an analysis of the influence of hydrogeological conditions on the stability of open pit slopes located within zones of tectonic disturbance. Based on field investigations and long-term hydrogeological monitoring conducted within the Almalyk ore cluster (Kalmakyr, Yoshlik-I, and Kurgashinkan deposits), the key factors affecting slope stability have been identified. It has been established that groundwater inflows from fractured and karstified Paleozoic rocks, as well as the presence of flooded abandoned pits, significantly increase the risk of slope deformation and failure. A special role is attributed to tectonic faults, which act as filtration channels for groundwater, leading to …

Development Of Technical Solutions To Prevent The Formation Of Sludge Regime At The Bottom Of A Well, Rustam Umarkhanovich Juraev, Jonibek Tursunov

Technical science and innovation

The trouble-free process of drilling wells largely depends on the effective cleaning of the borehole. The formation of a slurry regime at the bottom of the well leads to the process of repeated crushing of drilling fines, which in turn leads to a decrease in the mechanical drilling speed, to an increase in the energy consumption of the rock-crushing tool for repeated crushing, and also increases the risk of oil seals. In addition, the formation of a slurry regime at the bottom of the well increases the intensity of abrasive wear of the drilling rig. This article provides a theoretical …

The Well-Being Of International Doctoral Students—What Does It Look Like, What Affects It, And How Can We Support It?, Sean Nicholas, Pinjia Chan, Ivana Chan

Journal of Comparative & International Higher Education

There are multiple reviews on the well-being of international students and doctoral students, but to our knowledge, none on the well-being of international doctoral students. We undertook a scoping review to understand the state of well-being of international doctoral students, the factors that affect it, and the strategies that support it. We searched PsycInfo, EBSCO, Scopus, and ERIC for full-text, peer-reviewed articles published in English from 2003–2023. Fourteen studies were included in our scoping review. These studies suggest that international doctoral students report relatively low well-being in terms of negative emotions, attitudes toward the self, and social relationships. Their well-being …

Physical Design (Pd) Modeled As A Directed Acyclic Graph (Dag) For Advanced Analytics, Avijeet Somani, Sagar Karandikar, Parthasarathy Ranganathan, Akanksha Jain

Defensive Publications Series

Physical design (PD) within very-large-scale integration (VLSI) is complex, iterative, and time-consuming, featuring extended design cycles and requiring significant manual debugging that is heavily reliant on individual experience of the engineer. This disclosure describes techniques to model the entire PD lifecycle of a VLSI design as a conceptual graph by leveraging historical PD data. The conceptual graph can be employed to represent the entire design history as a directed acyclic graph (DAG). The DAG can help capture the cause-and-effect relationships between jobs with sequential edges representing stage transformations and iterative refinement edges documenting causes for re-runs.
