GRB 990123 may have radiated more than one solar mass equivalent in just its gamma emissions. Though this may be within the upper limit of the binding energies available from neutron stars in the Schwarzschild metric, it is difficult to imagine a process with the required efficiency of conversion to gamma rays. Neutron stars of ∼ 10M⊙ are permitted in the Yilmaz metric. A merger of two neutron ...

The Euler-Bernoulli beam theory is used to establish the vibration differential equation of rigid catenary, cantilever support device equivalent spring, and pantograph three mass block model. double-pantograph-catenary (DPC) dynamic coupling model established by using penalty function, utilize Newmark-β solved model, verifying reliability with field test contact forces catenary system (RCS) Xi’...

Abstract. Artificial impervious surface area (ISA) documents the human footprint. Accurate, timely, and detailed ISA datasets are therefore essential for global climate change studies urban planning. However, due to lack of sufficient training samples operational mapping methods, at a 10 m resolution still lacking. To this end, we proposed method leveraging multi-source geospatial data. Based o...

ABSTRACT In experiments conducted in growth chambers with the susceptible wheat cultivar BR 23, interactions between five temperatures (10, 15, 20, 25 and 30°C) eleven wetting periods were assessed for fusarium head blight (FHB) intensity. Each temperature consisted of one experiment hours corresponded to treatments. The disease occurred even at 10ºC, minimum tested temperature, maximum inciden...

Linear diffusion layer is an important part of lightweight block ciphers and hash functions. This paper presents an efficient class of lightweight 4x4 MDS matrices such that the implementation cost of them and their corresponding inverses are equal. The main target of the paper is hardware oriented cryptographic primitives and the implementation cost is measured in terms of the required number ...
