Efficiency of Self-Injection Locked Lasers
PhotonicsThe integrated III-V self-injection locked (SIL) laser exhibits excellent linewidth compression, noise reduction, and frequency stability. However, the laser’s low efficiency and fluctuating output power severely limit its applications in optical ...

Cascaded Fiber-Optic Time Synchronization System with Different Modulation Format
PhotonicsHigh-precision time and frequency transfer plays a pivotal role in metrology, geodesy, deep-space exploration and other scientific applications. Based on current time synchronization research, extending point-to-point schemes into a wide-area network can

A comprehensive multilevel model meta-analysis of self-concept interventions
, 2006 The efficacy of self-concept interventions has previously been examined through traditional meta-analytic methods, and a host of moderators of intervention outcomes have been identified (O’Mara, Marsh, & Craven, 2004; Haney & Durlak, 1998; Hattie, 1992).

, 2013 —Successive-relaying-aided (SR) cooperative multi-carrier (MC) space–time shift keying (STSK) is proposed for frequency-selective channels. We invoke SR to mitigate the typical 50% throughput loss of conventional half-duplex relaying schemes and MC code ...

Suppression of stimulated Brillouin scattering in high power fibre lasers and amplifiers
, 2009 Fibre sources in high power devices have significant advantages over conventional gas and solid state lasers. However, for applications that require the so-called singlefrequency sources with narrow linewidths, the output power is low mainly because of ...

Testing for Mean-Coherent Regular Risk Spanning [PDF]
Coherent risk measures have received considerable attention in the recent literature.Coherent regular risk measures form an important subclass: they are empirically identifiable, and, when combined with mean return, they are consistent with second order ...

, 2006 There is a longstanding debate in the self-concept literature surrounding the causal ordering of self-concept and academic achievement. Some researchers have argued that self-esteem has no positive impact upon performance (Baumeister, Campbell, Krueger &
