Inorg Chem. 2007 Dec 10;46(25):10501-9. doi: 10.1021/ic7015319. Epub 2007 Nov 15.

New polynuclear coordination species containing the ditopic bis(1-imidazolyl)methane (Bim) ligand have been prepared as microcrystalline powders and structurally characterized by ab initio X-ray powder diffraction methods. [Zn(CH3COO)2(Bim)]n contains 1D chains with tetrahedral metal atoms bridged by Bim ligands; [CdBr2(Bim)]n...

Eightfold 40-320 Gbit/s phase-coherent multiplexing and 320-40 Gbit/s demultiplexing using highly nonlinear fibers.

Optics letters

Wu X, Bogoni A, Yilmaz OF, Nuccio S, Wang J, Willner AE.
PMID: 20517454
Opt Lett. 2010 Jun 01;35(11):1896-8. doi: 10.1364/OL.35.001896.

We experimentally demonstrate 40-320Gbit/s phase-coherent multiplexing based on cross-phase modulation and subsequent 320-40Gbit/s demultiplexing using cross-phase-modulation-induced frequency shift in highly nonlinear fibers. An average penalty of approximately 7dB at a 10(-9) bit-error rate is observed after the nonlinear processes....

Bit-rate-variable and order-switchable optical multiplexing of high-speed pseudorandom bit sequence using optical delays.

Optics letters

Wu X, Wang J, Yilmaz OF, Nuccio SR, Bogoni A, Willner AE.
PMID: 20847772
Opt Lett. 2010 Sep 15;35(18):3042-4. doi: 10.1364/OL.35.003042.

We experimentally demonstrate high-speed optical pseudorandom bit sequence (PRBS) multiplexing with coarse and fine bit-rate tuning capability and a switchable order using optical delays. Data multiplexing of 80 Gbit/s and 160 Gbit/s is shown, each with a tunable rate...

640 Gbits/s photonic logic gates.

Optics letters

Bogoni A, Wu X, Bakhtiari Z, Nuccio S, Willner AE.
PMID: 21124577
Opt Lett. 2010 Dec 01;35(23):3955-7. doi: 10.1364/OL.35.003955.

We demonstrate 640 Gbits/s all-optical A AND B, and Ā AND B logic functions using pump depletion in a periodically poled lithium niobate waveguide. Bit-error-rate measurements show the effectiveness of the scheme, with a penalty of

Infective endocarditis presents as isolated splenomegaly.

Journal of cardiovascular disease research

PMID: 21716757
J Cardiovasc Dis Res. 2011 Jan;2(1):71-3. doi: 10.4103/0975-3583.78601.

Sub acute left-sided bacterial endocarditis is a serious condition that may be overlooked due to highly variable clinical manifestations. We present the case of a 45-year-old man who presented with complaints of fullness in his abdomen and splenomegaly that...

PMID: 22282692
J Blood Med. 2010;1:131-4. doi: 10.2147/JBM.S9529. Epub 2010 Jul 14.

BACKGROUND: Homocysteinemia has been established as a risk factor for cardiovascular disorders by the American Heart Association.1 Cerebrovascular accident (stroke) is presently ranked as one of the leading causes of morbidity and mortality worldwide. The aim of this study...

Observation of Feshbach resonances in an ultracold gas of 52Cr.

Physical review letters

Werner J, Griesmaier A, Hensler S, Stuhler J, Pfau T, Simoni A, Tiesinga E.
PMID: 15904366
Phys Rev Lett. 2005 May 13;94(18):183201. doi: 10.1103/PhysRevLett.94.183201. Epub 2005 May 09.

We have observed Feshbach resonances in collisions between ultracold 52Cr atoms. This is the first observation of collisional Feshbach resonances in an atomic species with more than one valence electron. The zero nuclear spin of 52Cr and thus the...

New structural motifs, unusual quenching of the emission, and second harmonic generation of copper(I) iodide polymeric or oligomeric adducts with para-substituted pyridines or trans-stilbazoles.

Inorganic chemistry

Cariati E, Roberto D, Ugo R, Ford PC, Galli S, Sironi A.
PMID: 15907137
Inorg Chem. 2005 May 30;44(11):4077-85. doi: 10.1021/ic050143s.

The structural, emissive, and nonlinear optical properties of new CuI adducts with para-substituted trans-stilbazolic and pyridinic ligands are reported. Single-crystal X-ray diffraction results indicate that the para-substituent on the organic ligand greatly influences the structural motif by its steric...

Hodgkin's lymphoma masquerading as vertebral osteomyelitis in a man with diabetes: a case report.

Journal of medical case reports

Bender Ignacio RA, Liu AY, Sohani AR, Vyas JM.
PMID: 20370895
J Med Case Rep. 2010 Apr 06;4:102. doi: 10.1186/1752-1947-4-102.

INTRODUCTION: Infection and malignancy often have common characteristics which render the differential diagnosis for a prolonged fever difficult. Imaging and tissue biopsy are crucial in making a correct diagnosis, though differentiating between chronic osteomyelitis and malignancy is not always...

Highly emitting concomitant polymorphic crystals of a dinuclear rhenium complex.

Journal of the American Chemical Society

Quartapelle Procopio E, Mauro M, Panigati M, Donghi D, Mercandelli P, Sironi A, D'Alfonso G, De Cola L.
PMID: 20866093
J Am Chem Soc. 2010 Oct 20;132(41):14397-9. doi: 10.1021/ja106772v.

The dinuclear complex [Re(2)(μ-Cl)(2)(CO)(6)(μ-4,5-(Me(3)Si)(2)pyridazine)] gives in the solid state two polymorphs (yellow, 1Y, and orange, 1O), which can be either concomitantly or separately obtained on varying the crystallization rate. Both crystal phases exhibit intense photoluminescence from the lowest lying...
