a r t i c l e i n f o This paper examines the effects of conversion of one type of physical trade restrictions into another on the intra-country wage inequality in a standard 2 × 2 × 2 Heckscher–Ohlin–Samuelson model. It shows that a conversion of an import-quota into an equivalent voluntary export restraint raises wage-inequality in the country importing the unskilled-labor intensive good and ...

We show that regularizing divergent integrals is crucially important when applied to the loop diagrams corresponding to quantum corrections to the coupling of the “gravitational” scalar field due to the interaction among matter fields. We use the method of continuous spacetime dimensions to demonstrate that WEP is a robust property of the Brans-Dicke theory beyond the classical level, hence cor...

background: since 1996 the assessment of environmental gamma radiation dose in residential areas of iranian towns and cities has been accomplished for 10 counties. as a practical method and based on the results of a pilot study, in order to attribute the final results to the whole residential area of a town five stations were selected for every town. the location of individual station was studi...

This paper analyses two front-end receiver architectures intended for GSM900 use; (i) A direct-conversion receiver, and (ii) a low-IF receiver using a poly-phase filter. The aim is to determine the circuit performance required for GSM operation and to compare this to current state-of-the-art CMOS performance. The analysis shows that direct-conversion receivers fail to meet specifications when b...

We show how to build generic DEVS models to facilitate simulation of mixed signal Hardware Description Language models within a DEVS simulator. We present the models required, and the conversion procedures for a subset of VHDL called sAMS-VHLD. Hierarchical models written in sAMS-VHDL that utilize Processes, Signals and Simultaneous Statements are be simulated in the CD++ toolkit by elaborating...

Dynamic Frequency Warping (DFW) offers an appealing alternative to GMM-based voice conversion, which suffers from ”over-smoothing” that hinders speech quality. However, to adjust spectral power after DFW, previous work returns to GMMtransformation. This paper proposes a more effective DFWwith amplitude scaling (DFWA) that functions on the acoustic class level and is independent of GMM-transform...

The widespread application of ω-transaminases as biocatalysts for chiral amine synthesis has been hampered by fundamental challenges, including unfavorable equilibrium positions and product inhibition. Herein, an efficient process that allows reactions to proceed in high conversion in the absence of by-product removal using only one equivalent of a diamine donor (ortho-xylylenediamine) is repor...
