Non-orthogonal multiple access (NOMA) has potentials to improve the performance of multi-beam satellite systems. The optimization in satellite-NOMA systems could be different from that terrestrial-NOMA systems, e.g., considering distinctive channel models, metrics, power constraints, and limited flexibility resource management. In this paper, we adopt a metric, offered capacity requested traffi...
Hadrontherapy is ideally suited to treat tumours that are deep-seated, located close to critical organs and respond poorly to conventional photon or electron radiotherapy. The use of proton and carbon ion beams for therapy will not only improve the tumour control probability for certain malignant diseases, but also reduce long-term complications in the surrounding healthy tissue. Therapy using ...
high spin states in the neutron rich nucleus 191os has been populated for the first time using the82se+192os deep-inelastic reaction at 460 mev beam energy using the alpi accelerators at the laboratorynazionali di legnaro, italy. high fold γ-γ coincidences were acquired with the 4π spectrometer gaspdetector array, consisting of 40 compton-suppressed, large-volume germanium detectors with an inn...
Analytical methods of electron beam power evaluation for electron-beam welding with deep penetration
Landscapes as dynamic relations between people and worlds are always incomplete. They partial understandings, evolving knowledges, edited images unfinished stories of our designed undesigned environments. Gaps within landscapes can reveal histories omitted individuals silenced, but this open-endedness also provide opportunities to contribute participate. In paper I explore how under constructio...
This study aimed to figure out students' responses toward using the fix-up options strategy in comprehending text personal recount. The qualitative method was used collect data. sample second grade of Pos Keadilan Peduli Ummat (PKPU) junior high school students, which consisted 22 students. open-ended questionnaire distributed as instrument for collecting It consists three questions that relate...
abstract the current research tried to examine the impact of multiple intelligence (mi) and its components on multiple choice (mc) and open ended (oe) reading comprehension tests. ninety six students of high school in grade four took part in this study. to collect data, participants completed multiple intelligence (mi) questionnaires along with a multiple choice (mc) and open ended (oe) forms ...
Nitrogen-fixing (diazotrophic) microorganisms regulate productivity in diverse ecosystems; however, the identities of diazotrophs are unknown in many oceanic environments. Using single-cell-resolution nanometer secondary ion mass spectrometry images of 15N incorporation, we showed that deep-sea anaerobic methane-oxidizing archaea fix N2, as well as structurally similar CN-, and share the produc...
UNLABELLED Lentiviral vectors are attractive tools for liver-directed gene therapy because of their capacity for stable gene expression and the lack of preexisting immunity in most human subjects. However, the use of integrating vectors may raise some concerns about the potential risk of insertional mutagenesis. Here we investigated liver gene transfer by integrase-defective lentiviral vectors ...
The performance of an Earth-to-space optical telecommunications system is degraded by distortion (scintillation and tilt) of the beam as it propagates through the turbulent atmosphere. Conventional approaches to correct distortions that are based on natural or artificial guide stars are useful in, for example, astronomical imaging, but have practical difficulties or are not adequate to correct ...
