The current wave of COVID-19 outbreak has created new strategical challenges for policy officials the industrial sector across world. effect is more in developing economies where already struggling its stability. This study introduces impact on corporate investment behavior non-financial publicly listed firms Pakistan. To achieve objective, we employ panel data ranging from 2010 to 2020 and app...

Fine structure of the density distribution in giant molecular clouds (GMCs) around W43 (G31+00+90 km s−1at ∼5.5 kpc) was analyzed using FUGIN* CO-line survey at high-angular (20”∼0.5 pc) and velocity (1.3 s−1) resolutions (*Four-receiver-system Unbiased Galactic Imaging with Nobeyama 45-m telescope). The GMCs show highly turbulent structures, eddies are found to exhibit spherical bubble morphol...

ABSTRACT We compare seven fraud prediction models with a cost-based measure that nets the benefits of correctly anticipating instances against costs borne by incorrectly flagging non-fraud firms. find even best trade off false to true positives at rates exceeding 100:1. Indeed, high number makes all considered too costly for auditors implement, in subsamples where misreporting is more likely. F...

Mouse L-929 cells (L cells), human oligodendroglioma cells, and rat glioma cells were persistently infected with vesicular stomatitis virus (VSV) mutant tsG31 and maintained for at least 4 years at 37 degrees C. The striking observation in this study was that there is a marked difference in neurovirulence among the persistent infections (PIs) derived from the three cell lines. tsG31 VSV derived...

Ferroelectrets have promoted a variety of exciting flexible sensors, actuators, and microenergy harvesters. However, most ferroelectrets been fabricated from non-degradable petro-based resins, thus the recycling these materials constitutes big challenge. This article reports biodegradable bioabsorbable ferroelectret films made polylactic acid (PLA) resins for highly sensitive transducer applica...

With global warming, extreme weather such as floods and waterlogging occurs more frequently seriously in recent years. During the flood, surrounding environment of GNSS (Global Navigation Satellite System) station will change volume water increases. Considering multipath error is directly relevant to observation environment, thus, influence flood on L4 combination (a geometry-free ionosphere-fr...

With an increasing demand for self-powered microelectronics to be used in scientific tasks and exploration missions extreme environments, the implementation of piezoelectric energy harvesting at high temperature is important research focus renewable sources. Piezoelectric composites made from ceramic fillers polymer matrices combine electromechanical coupling with flexibility, resulting a versa...
