Article Abstract

We analyze phase matching with reference to frequency doubling in nanosized quadratic waveguides encompassing form birefringence and supporting cross-polarized fundamental and second-harmonic modes. In an AlGaAs rod with an air void, we show that phase-matched second-harmonic generation could be achieved in a wide spectral range employing state-of-the-art nanotechnology.

Rules can control the listener's behavior, yet few studies have examined variables that quantitatively determine the extent of this control relative to other rules and contingencies. To explore these variables, we employed a novel procedure that required a choice between rules. Participants clicked two buttons on a computer screen to earn points exchangeable for money.

A method for determination of ten kinds of sweeteners in soybean products by multi-plug filtration cleanup (-PFC) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The sample was extracted with acetonitrile (containing 1% formic acid), degreased by using -hexane liquid-liquid extraction and purified by solid phase extraction using an -PFC column (Oasis PRiME HLB). The analytes were separated by using a Waters ACQUITY UPLC® BEH C (2.

Introduction: Hemophilia A, an X-linked recessive bleeding disorder, is characterized by reduced factor VIII (FVIII) activity. Hemophilia A can significantly impact a person's quality of life because of the risk of spontaneous bleeding. Treatment for hemophilia A aims to prevent bleeding from occurring.

Adolescent male rodents and humans exhibit impairments in extinguishing learned fear. Here, we investigated whether female adolescent rats exhibit such impairments and if extinction is affected by the estrous cycle as in adults. Following fear conditioning to a discrete cue, female adolescent Sprague Dawley rats were extinguished either around the onset of puberty, when estrous cycling begins, or across different stages of the estrous cycle.

Background: Lower extremity alignment in knee osteoarthritis (OA) is conventionally assessed using standing radiographs. However, symptoms often manifest during gait. Understanding dynamic alignment during gait may help characterize disease progression and inform treatment strategies.
