We measured the relative positions between two pairs of compact extragalactic sources (CESs), J1925-2219 \& J1923-2104 (C1--C2) and J1928-2035 (C1--C3) on 2020 October 23--25 2021 February 5 (totaling four epochs), respectively, using Very Long Baseline Array (VLBA) at 15 GHz. Accounting for deflection angle dominated by Jupiter, as well contributions from Sun, planets other than Earth, Moon Ga...

Founded by the World Me te o ro log i cal Or ga ni za tion (WMO) and the United Na tions En vi ron ment Programme (UNEP) in 1988, the In ter gov ern men tal Panel on Cli mate Change (IPCC) is en gaged in a unique sci en tific as sess ment pro cess. Not only is the IPCC ex plic itly tied to the United Na tions Frame work Con ven tion on Cli mate Change (UNFCCC) as its pol icy au di ence, but it ...

Abstract The Laplace transform of the first exit time from a finite interval by a spectrally negative αstable Ornstein-Uhlenbeck process (1 < α ≤ 2) is provided in terms of the Wright’s generalized hypergeometric function 2Ψ1. The Laplace transform of first passage times is also derived for some related processes such as the process killed when it enters the negative half line and the process c...

BACKGROUND Tumor volumes of more than 100 ml and the presence of primary metastases have been identified as determinants of poor prognosis in patients with Ewing tumors. We sought to assess the prevalence of critical tumor size and primary metastases in a large national sample of patients at the time of first diagnosis and to identify factors that are associated with their occurrence. PATIENT...

o bjectives: correct determination of working length is an important step for suc- cess of endodontic therapy. conventional radiography has limitations in providing the accurate location of apical foramen. for this reason, electronic apex locators (eals) were developed to shorten the treatment time and decrease the radiation dose. the aim of this study was to evaluate the accuracy of root zx ea...

The regulation of the frequency and line power flow in interconnected networks is considered to be a key aspect load control (LFC). This article broaches modern network composed three areas including traditional generation units taking into account non-linearities, also renewable energy sources (RESs) storage (ES) are involved grid paradigm. Two forms RESs included analysis, which photovoltaic ...

The source and target reliability in SAT network is de- fined as the flawless transmission from the source node to all the other nodes. In some references, the SAT pro- cess has been followed between all the node pairs but it is very time-consuming in today’s widespread networks and involves many costs. In this article, a method has been proposed to compare the reliability in complex networks b...

Affordable housing remains a major problem for National and County Governments as the increase in population, particularly low-income earners, rises significantly annually. It is evident that despite efforts from both national county governments, Kiambu still lags provision of affordable housing. The development agenda seems not to be getting required traction at level with little participation...

in today’s competitive world, psychological capital and work activities are considered as a key factor to suc cess and survival for organizations. so far, the literature has recognized various items that affect work activi ties in organizations. the study analyzes how psychological capital predicts work activities both directly and through the mediating role of innovation, subjective well-being...
