AbstractFast ignition of inertial fusion targets driven by quasi-monoenergetic ion beams is investigated by means of numerical simulations. Light and intermediate ions such as lithium, carbon, aluminum and vanadium have been considered. Simulations show that the minimum ignition energies of an ideal configuration of compressed Deuterium-Tritium are almost independent on the ion atomic number. However, they are obtained for increasing ion energies, which scale, approximately, as Z2, where Z is the ion atomic number. Assuming that the ion beam can be focused into 10 µm spots, a new irradiation scheme is proposed to reduce the ignition energies. The combination of intermediate Z ions, such as 5.5 GeV vanadium, and the new irradiation scheme allows a reduction of the number of ions required for ignition by, roughly, three orders of magnitude when compared with the standard proton fast ignition scheme.

Liposarcoma (LPS) is the most common soft tissue sarcoma. Myxoid LPS (MLPS) is the second most common subtype of LPS and accounts for 25% to 50% of all LPSs. Like most other soft tissue sarcomas, the mainstay of treatment for LPS is inevitably surgery. Multidisciplinary approaches, including surgery, chemotherapy, and radiotherapy, have been successful in the treatment of LPS during the last three decades. Even so, recurrence of LPS remains challenging. Carbon ion beams produce increased energy deposition at the end of their range to form a Bragg peak while minimizing irradiation damage to surrounding tissues, which facilitates more precise dosage and localization than that achieved with photon beams. Furthermore, carbon ion beams have high relative biologic effectiveness. We herein describe a patient who developed recurrent MLPS in the right calf after two surgeries and underwent carbon ion radiotherapy (CIRT), achieving complete disappearance of the tumor. The patient developed Grade 1 radiation dermatitis 30 days after CIRT, but no other acute toxicities were observed. The tumor had completely disappeared by 120 days after CIRT, and the patient remained disease-free for 27 months after CIRT. The CARE guidelines were followed in the reporting of this case.

Abstract For crop production to cope with problems driven by climate change, such as salinity, drought and extreme temperatures, the Bangladesh Institute of Nuclear Agriculture (BINA) released a late Boro rice variety, 'Binadhan-14' in 2013 which is tolerant to high temperature, has short duration (105-115 days) and gives average yield of 6.9 t/ha. This variety was developed by irradiating the seeds of 'Ashfal', a local salt-tolerant landrace of rice, with 200 Gy of carbon-ion beams. The late-transplanting potential of this variety also helps in avoiding seedling injury due to severe cold. Another variety, 'Binadhan-19', was developed by irradiating the seeds of 'NERICA-10' rice with 40 Gy of carbon-ion beams. This was released by the National Seed Board of Bangladesh (NSB) in 2017 as a drought-tolerant, short-duration (95-105 days) and high-yielding (average 4.0 t/ha) variety for the Aus growing season. BINA developed a salt-tolerant wheat variety, 'Binagom-1', by selecting from a segregating population, obtained from NIAB, Pakistan. This variety was released in 2016; it can tolerate salinity (up to 12 dS/m) and produces an average yield of 2.8 t/ha. Apart from these, BINA developed four salt-tolerant groundnut varieties ('Binachinabadam-5', 'Binachinabadam-6', 'Binachinabadam-7' and 'Binachinabadam-9') by irradiation with gamma-rays. All these four varieties can tolerate salinity (up to 8 dS/m) from flowering to maturity and produce pods at 1.8-3.4 t/ha under saline soil conditions. These climate-resilient varieties are playing a significant role in food security and enhancing the nutritional status of the people of Bangladesh.
