The long noncoding RNA MALAT1 (metastasis-associated lung adenocarcinoma transcript 1), also known as MALAT-1 or NEAT2 (nuclear-enriched abundant transcript 2), is a highly conserved nuclear noncoding RNA (ncRNA) and a predictive marker for metastasis development in lung cancer. To uncover its functional importance, we developed a MALAT1 knockout model in(More)
The popular IEEE 802.11 WLAN is known to achieve relatively small throughput performance compared to the underlying physical layer (PHY) transmission rate. This is due mainly to the large overheads composed of medium access control (MAC) header, PHY preamble/header, backoff time, acknowledgement (ACK) transmission, and some inter-frame spaces (IFSs). Since(More)
— The popular IEEE 802.11 Wireless Local Area Network (WLAN) is based on a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA), where a station listens to the medium before transmission in order to avoid collision. If there exist stations which can not hear each other, i.e., hidden stations, the potential collision probability increases, thus(More)
—We propose a novel energy efficient communication strategy, called SP-TPC, for IEEE 802.11 Wireless LANs (WLANs). SP-TPC utilizes both transmit power control (TPC) and PHY rate adaptation in order to minimize the communication energy consumption while maximizing the throughput performance. When the TPC is employed in the 802.11 WLAN, the overall(More)
Acute sleep loss increases pro-inflammatory and synaptic plasticity-related molecules in the brain, including interleukin-1 beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and brain-derived neurotrophic factor (BDNF). These molecules enhance non-rapid eye movement sleep slow wave activity (SWA), also known as electroencephalogram delta power, and(More)
I n addition to the wireless telephony boom, a similar exponentially increasing trend in wireless data service— for example, short message service (SMS)—is visible as technology advances. We develop a structural model to examine user demand for voice service and SMS. Specifically, we measure the own-and cross-price elas-ticities of these services. The(More)
WLAN technology has been shown a revolutionary development during the last decade. Recently popularized IEEE 802.11a/g-based products can support up to 54 Mbps PHY (Physical layer) rate and give much freedom to access the Internet wirelessly. However, the 802.11 MAC (Medium Access Control) protocol has relatively large overhead in order to robustly deal(More)
In this paper, we present a real application system based on wireless sensor network (WSN) for fence surveillance which is implemented on our development platform for WSN, called ANTS (An evolvable Network of Tiny Sensors). Our system, called the WFS system, is expanded to connect and control a robot (UGV/UAV) and a camera sensor network for the purpose of(More)
For the first time in the WLAN technology, multi-user downlink transmission will be made possible by the upcoming IEEE standard, 802.11ac. In this paper, we will report its current status, focusing on the MAC modifications and enhancements that are necessary to support the unique feature of downlink multi-user MIMO transmission. Specifically, the technique(More)
