Propagation loss study of very compact GaAs/AlGaAs substrate removed waveguides.

Optics express

Shin J, Chang YC, Dagli N.
PMID: 19259176
Opt Express. 2009 Mar 02;17(5):3390-5. doi: 10.1364/oe.17.003390.

Very compact GaAs/AlGaAs optical waveguides with propagation loss as low as 0.9 dB/cm at lambda=1.55 microm were demonstrated using substrate removal and evaporated Si for index loading. Loss components were identified and minimized through process and waveguide design. Process...

Cyanosis in atrial septal defect without pulmonary hypertension: a case of platypnea-orthodeoxya syndrome.

Interactive cardiovascular and thoracic surgery

Di Bella I, Pasquino S, Da Col U, Ragni T.
PMID: 17670345
Interact Cardiovasc Thorac Surg. 2005 Feb;4(1):15-7. doi: 10.1510/icvts.2004.090811. Epub 2004 Dec 17.

Cyanosis in atrial septal defect typically occurs when pulmonary hypertension develops. Platypnea-orthodeoxya is an uncommon syndrome, still under debate, characterized by breathlessness and arterial oxygen desaturation exacerbated in the upright position. An interatrial communication is a common finding in...

[Physiopathology of genitourinary prolapse].

Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie

Ragni E, Haab F, Delmas V, Costa P.
PMID: 19969260
Prog Urol. 2009 Dec;19(13):926-31. doi: 10.1016/j.purol.2009.09.036. Epub 2009 Nov 14.

The physiopathology of urogenital prolapse is multifactorial, a combination of the interaction between constitutional and acquired factors resulting in the weakening of perineal support. Genetic modifications contribute to the occurrence of prolapse (proof level 2). Differences relating to types...

Tubercular abscess of pons in a child with quadriparesis.

A photonic analog-to-digital converter based on an unbalanced Mach-Zehnder quantizer.

Optics express

Sarantos CH, Dagli N.
PMID: 20639945
Opt Express. 2010 Jul 05;18(14):14598-603. doi: 10.1364/OE.18.014598.

A Mach-Zehnder modulator (MZM) based analog to digital converter (ADC) is described. The signal to be digitized is applied to a single electrode of a high speed unbalanced modulator that acts as a quantizer. The rest of the system...

The FMRP regulon: from targets to disease convergence.

Frontiers in neuroscience

Fernández E, Rajan N, Bagni C.
PMID: 24167470
Front Neurosci. 2013 Oct 24;7:191. doi: 10.3389/fnins.2013.00191.

The fragile X mental retardation protein (FMRP) is an RNA-binding protein that regulates mRNA metabolism. FMRP has been largely studied in the brain, where the absence of this protein leads to fragile X syndrome, the most frequent form of...

The correct assignment of stereochemistry in di-μ-dichlorido-bis{bis[2-(5-benzylsulfonyl)-3-fluoro-2-(pyridin-2-yl)phenyl-κ2N,C1]iridium(III)} toluene monosolvate.

The title complex, [Ir2(C18H13FNO2S)4Cl2]·C7H8, was crystallized from dichloromethane solution under a toluene atmosphere. It is a dimeric complex in which each of the two Ir(III) centres is octahedrally coordinated by two bridging chloride ligands and by two chelating cyclometalated...

Two stage hip revision in periprosthetic infection: results of 41 cases.

BACKGROUND: two-stage revision is considered the best treatment approach for the eradication of chronic joint infection. We report the outcome of 41 consecutive patients with infected hip prostheses, treated between 2000 and 2005, with two-stage revision using an antibiotic-loaded...

Opioidergic and dopaminergic manipulation of gambling tendencies: a preliminary study in male recreational gamblers.

Frontiers in behavioral neuroscience
