The present paper is a five-week content analysis of crime stories reported on television news. The sample consists of three nightly newscasts available on a rural, midwestern cable system. Included are nightly newscasts from a national network, a big city television station, and a small town channel. Findings from this exploratory study show that these three sources of television news differ s...

background: baculoviral inhibitor of apoptosis repeat-containing 5 (birc5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. the copy number of birc5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. methods: forty tumor tiss...

To enhance the system throughput and to extend coverage of IEEE 802.16 networks, relay stations can be implemented. If a user station is attached to the base station (BS) through several relays stations (RS), a multi-hop communication occurs. To enable multi-hop communication, the IEEE 802.16j standard proposes two approaches how RSs can be implemented into the network. The first approach group...

Reconfigurable intelligent surface (RIS) is a revolutionary technology to enhance both the spectral efficiency and energy of wireless communication systems. However, most existing contributions mainly focused on study passive RIS, which suffers from “double fading” effect. On other hand, active equipped with amplifiers, can effectively address this issue. In letter, we propose an RIS-aided simu...

With the demand for fast response of magnetic field measurement and development laser diode technology, self-oscillating laser-pumped atomic magnetometers have become a new trend. In this work, we designed portable VCSEL-pumped Cs atom magnetometer, including probe (optical path) circuits. The signal amplification feedback loop VCSEL control unit, cell temperature unit were realized. We tested ...

We give a simplified proof of regularizing effects for first-order Hamilton-Jacobi Equations of the form ut+H(x, t, Du) = 0 in R ×(0,+∞) in the case where the idea is to first estimate ut. As a consequence, we have a Lipschitz regularity in space and time for coercive Hamiltonians and, for hypo-elliptic Hamiltonians, we also have an Hölder regularizing effect in space following a result of L. C...

In a laboratory experiment we show that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been removed. Firms are therefore forced to pay higher wages after the removal of the minimum wage than before its introduction. As a c...

A Contribution to the Empirics of Reservation Wages This paper provides evidence on the behavior of reservation wages over the spell of unemployment using high‐frequency longitudinal data. Using data from our survey of unemployed workers in New Jersey, where workers were interviewed each week for up to 24 weeks, we find that self‐reported reservation wages decline at a modest rate over the spel...
