OBJECTIVE Adolescence is a period of developing emotional regulation. However, alexithymia has rarely been examined during this period. The objective of this study is to examine the factor structure and internal consistency of the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20K) in normal adolescents in South Korea. METHODS The TAS-20K was administered to a sample of 290 adol...

Here we use low-temperature scanning tunneling microscopy and spectroscopy to reveal the roles of narrow electronic band in two 1$T$-TaS$_2$ related materials (bulk 4$H_{\rm b}$-TaS$_2$). b}$-TaS$_2$ is a superconducting compound with alternating 1$H$-TaS$_2$ layers, where layer has weak charge density wave (CDW) pattern reduces CDW coupling between adjacent layers. In b}$-TaS$_2$, observe loca...

This paper presents the average capacity and error performance of 3×4 orthogonal space time block code (OSTBC) and transmits antenna selection (TAS) with multiple antennas. In TAS scheme, we consider one transmit antenna is selected for transmit signals at the secondary transmitters and the secondary receiver applies the maximum likelihood (ML). In 3×4 OSTBC scheme, we consider three transmit a...

Most location-aware mobile applications only make use of the user’s current location, but there is an opportunity for them to infer the user’s future locations. We present Trajectory-Aware Search (TAS), a mobile local search application that predicts the user’s destination in real-time based on location data from the current trip and shows search results near the predicted location. TAS demonst...

The outage probability (OP) performance of multiple-relay incremental-selective decode-and-forward (ISDF) relaying mobile-to-mobile (M2M) sensor networks with transmit antenna selection (TAS) over N-Nakagami fading channels is investigated. Exact closed-form OP expressions for both optimal and suboptimal TAS schemes are derived. The power allocation problem is formulated to determine the optima...

The performance of an underlay cognitive (secondary) dual-hop relaying system with multiple antennas and hardware impairments at each transceiver is investigated. In particular, the outage probability of the end-to-end (e2e) communication is derived in closed-form, when either transmit antenna selection with maximum ratio combining (TAS/MRC), or TAS with selection combining (TAS/SC) are establi...
