This paper investigates the massive connectivity of low Earth orbit (LEO) satellite-based Internet-of-Things (IoT) for seamless global coverage. We propose to integrate grant-free non-orthogonal multiple access (GF-NOMA) paradigm with emerging orthogonal time frequency space (OTFS) modulation accommodate IoT access, and mitigate long round-trip latency severe Doppler effect terrestrial–satellit...
Observations of wind and ocean surface velocity vectors by along-track interferometry (ATI) with the synthetic aperture radar (SAR) are not only important for direct applications but also to increase understandings upper layer mixing, air–ocean interactions, mapping submesoscale (1–10 km) structures. An experimental bidirectional (BiDi) ATI acquisition mode TanDEM-X observes two squinted beams ...
The Keldysh theory of above-threshold ionization (ATI) is applied to few-cycle laser pulses in order to explore the potential of a recently published new method to measure "carrier-envelope phase difference" phenomena. In this experiment, the carrier-envelope phase difference dependent left-right asymmetry of few-cycle ATI was measured and investigated with a correlation technique. Here, we exp...
Existing measures of human rights abuses are often only available at the country-year level. Several more fine-grained exhibit spatio-temporal inaccuracies or reporting biases due to primary sources upon which they rely. To address these challenges, and increase diversity generally, this study provides first quantitative effort measure from textual records citizen-government interactions. Using...

The paper presents a methods to retrieve the speed of the sea surface from Along Track Interferometry (ATI) data beside the typical use for target speed retrieval, which is also mentioned. The describe technique provides for a data prefiltering in order to obtain the necessary accuracy because of the law speed range of the currents. Furthermore, an example of target velocity estimation is provi...
We perform numerical expe riments wit h a novel cellularautomaton fluid mod el. T he mod el has simple pair -in t eraction rules and works in arb it rarily man y dimensions; here we consider the twodimension al case . By observing the smoothing-out of the velocity profile of a shear flow and t he relax ati on of a shea r wave, we measure t he kin em ati c shear viscosity and obtain a value of R...
We present energy-resolved angular distributions of photoelectrons generated in above-threshold ionization (ATI) of nonaligned diatomic molecules N2 and O2 in high-intensity short laser pulses, with emphasis on the most energetic part of the spectra. The angular distribution for photoelectrons with energy of 10U(p) (U(p): ponderomotive energy), i.e., the plateau cutoff in ATI spectra, is found ...
