We study linear stability of an infinitely long, axisymmetric, cylindrical active liquid crystal (ALC) jet in a passive isotropic fluid matrix using a polar active liquid crystal (ALC) model. We identify three possible unstable modes (or mechanisms) as the result of the interaction between the flow and the active (or self-propelled) molecular motion. The first unstable mode is related to the po...

The GSM network, commonly called 2G, was designed during the 1980s when the Cold War was still on. Due to political pressure from European governments, the security of GSM was deliberately made weak to allow easy interception by law enforcement agencies. Despite strengthened security in subsequent mobile network technologies of 3G and 4G, the weak security of 2G represents the ‘weakest link’ an...

Ventilation in cities is crucial for the well being of their inhabitants. Therefore, local 1 governments require air ventilation assessments (AVAs) prior to the construction of new buildings. In 2 a standard AVA, however, only neutral stratification is considered, although diabatic and particularly 3 unstable conditions may be observed more frequently in nature. The results presented here indic...

    Home health care is a wide range of health care services that can be given in your home for an illness or injury (1). During last decade, home health care is taken into consideration seriously. The concept of home health care began in the 1850's when traveling health care professionals provided in-home visits to patients in need of health care and unable to seek such care on their own (2). ...

the relationship between added value of economic activities and the governments budget along with the impact of this budget on the employment of economic activities are among the issues that economic decision-makers and analysts assume to be crucial. classification of statistical data has not yet allowed experts and decision-makers to evaluate the governments role in production and employment i...

With the rapid development of urbanization and population growth, ecological environment in Yellow River Delta has undergone significant changes. In this study, Landsat satellite data Google Earth Engine (GEE) were utilized to dynamically evaluate changes eco-environmental quality region using remote sensing index (RSEI). Additionally, CASA model was used estimate net primary productivity (NPP)...

In this paper we describe the range of values that can be taken by the fractional weak discrepancy of a poset subject to forbidden r+ s configurations, where r+s = 4. Generalizing previous work on weak discrepancy in [5, 12, 13], the notion of fractional weak discrepancy wdF (P ) of a poset P = (V,≺) was introduced in [7] as the minimum nonnegative k for which there exists a function f : V → R ...
