Binary events are involved in many economic decision problems. In recent years, considerable progress has been made in diverse disciplines in developing models for forecasting binary outcomes. We distinguish between two types of forecasts for binary events that are generally obtained as the output of regression models: probability forecasts and point forecasts. We summarize specification, estim...

A novel method for quantum reactive scattering calculations is introduced and tested for simple model problems. It is shown to be efficient and quite accurate. The method is based on a simple modification to the time independent Schrödinger equation, (H2E)C50. It is obtained by setting (H2E)C5B where B is a localized boundary inhomogeneity. A necessary and sufficient number of arbitrary linearl...

Abstract. The article examines integration of cryptocurrencies as electronic payment systems in e-commerce enterprises. Practical usage Ethereum and Bitcoin systems, well factors that may affect their functionality are studied. Coinbase Commerce Bitpay, market leaders cryptocurrency providers, were analyzed to compare issues commission analysis with traditional LiqPay, PayPal. It is determined ...

Bu çalışma kapsamında farklı sonlu elemanlar yaklaşımları kullanılarak on katlı betonarme bir binanın radye temel kalınlıkları ve beton sınıfları değişiminin oturma üzerine etkisi araştırılmıştır. İlk yaklaşımda yapı düşey yükleri, sistemi alan yükü olarak etkitilmiştir. İkinci ise zemin birlikte modellenerek üst yükleri zemine doğrudan aktarılmıştır. İki yaklaşımla elde edilen modellerde 80-10...

this study examined the effects of implanted cortisol (to imitate chronic stress) on the hematological responses and cortisol values of female great sturgeon, huso huso, after an endoscopic operation. at the beginning of experiment, all the fish were examined using an endoscope to evaluate gonad development. then, in order to mimic chronic stress following surgery, capsules of cocoa?? butter co...

The dihydroxy C(50)-carotenoid, decaprenoxanthin, was produced by Aureobacterium sp. collected from sea water. The addition of D-psicose to the culture medium improved the growth of cells and the yield of the carotenoid. The (13)C-NMR spectrum of decaprenoxanthin, which has not previously been reported, was successfully measured.

published in Aduance ACS Abstracts, February 15, 1994. 0095-233819411634-0421$04.50/0 Fueled by the intense activity in fullerene chemistry and intrinsically interesting geometrical and topological features of fullerenes, several studies have focused on the fascinating mathematical properties of fullerenes. These studies included graph theoretical computations of the characteristic polynomials,...
