Direct and selective mono-N-pyridylation of trans-(R,R)-cyclohexane-1,2-diamine is described here. Facile preparation of a novel chiral 2-aminoDMAP core catalaphore via Cu catalysis has led to the development of various sulfonamide/2-aminoDMAPs as bifunctional acid/base organocatalysts (most in two steps overall), which have been shown to very effectively promote asymmetric conjugate addition of acetylacetone to trans-beta-nitroolefins with good to excellent yields (87-93%) and enantioselectivites (up to 99%).

Mn(III)-mediated radical C-C bond formation: Regioselective α′-allylation of α,β-unsaturated ketones
Tanyeli, Cihangir (2002-05-27)
Mn(OAc)(3)-mediated regioselective alpha'-allylation of alpha,beta-unsaturated enones is described. alpha'-Allyl alpha,beta-unsaturated enones are obtained through a radical process in good yields.
Timing observations from Rossi X-ray Timing Explorer (RXTE)
Beklen, Elif; Baykal, Altan; Department of Physics (2004)
In this thesis, RXTE observations of 4U 1907+09 are presented. Timing analysis of these data sets have yielded quasi periodic oscillations (QPOs) at orbital phases corresponding to the two flares in every orbital period. Known continuous spin down trend and QPO behaviour at the flares strongly suggest that a transient accretion disk occurs at the flares. Our findings strongly suggested that neutron star passes through the equatorial wind of Be companion star. During these passages a transient disk forms aro...
Analysis of the Junction Properties of C/GaSe<sub>0.5</sub>S<sub>0.5</sub>/C Back-to-Back Schottky-Type Photodetectors
Khanfar, Hazem K.; Qasrawi, Atef F.; Hasanlı, Nızamı (Institute of Electrical and Electronics Engineers (IEEE), 2015-4)
In this paper, a C/GaSe0.5S0.5/C metal-semiconductor-metal photodetector is suggested and described. The device is explored by means of current-voltage and capacitance-voltage (C-V) characteristics under different photoexcitation intensities. It was observed that the design of the back-to-back Schottky device has reduced the dark current of the normal Ag/GaSe0.5S0.5/C Schottky diode by 13 times and increased the photosensitivity from 3.8 to similar to 2.1x10(3). The device exhibited a barrier height of 0.84...
Competitive newsvendor problems with the same Nash and Stackelberg solutions
Serin, Yaşar Yasemin (2007-01-01)
Consider two newsvendors: (i) they compete satisfying substitutable demands searching Nash equilibrium or (ii) one is the leader deciding first, the other responds optimally playing a Stackelberg game. The leader profits more than she does in (i). We present conditions under which the leader's profit does not improve from (i) to (ii).
Authors' Reply to "Comments on 'Branch-Line Couplers Using Unequal Line Lengths"'
Toker, Canan; Oztne, Mustafa; GÜNALP, NİLGÜN (2018-09-01)
The comments of He et al. [1] pointed out an error in the above-cited paper [2, eq. (4)] , which occurred when copying the manuscript and it does not impair the rest of the paper because the correct formula is used throughout the analysis. So there should be no question about the correctness of the final results and conclusions of the paper [2].
