Response to lenalidomide in myelodysplastic syndromes with del(5q): influence of cytogenetics and mutations.
2012
Summary Lenalidomide is an effective drug in low-risk myelodysplastic syndromes (MDS) with isolated del(5q), although not all patients respond. Studies have suggested a role for TP53 mutations and karyotype complexity in disease progression and outcome. In order to assess the impact of complex karyotypes on treatment response and disease progression in 52 lenalidomide-treated patients with del(5q) MDS, conventional G-banding cytogenetics (CC), single nucleotide polymorphism array (SNP-A), and genomic sequencing methods were used. SNP-A analysis (with control sample, lymphocytes CD3+, in 30 cases) revealed 5q losses in all cases. Other recurrent abnormalities were infrequent and were not ass…

Dissidència política i repressió social al Pais Valencià a mitjan segle XVII
1984
CON EL PRESENTE TRABAJO ABORDAMOS LA PROBLEMATICA DE LA PROGRESIVA INTEGRACION DEL PAIS VALENCIANO EN LOS DESIGNIOS DE LA MONARQUIA HISPANICA. PONEMOS DE RELIEVE COMO LA DISIDENCIA POLITICA DE LAS CAPAS DIRIGENTES VALENCIANAS (PROTAGONISTAS DE TACTICAS MAFIOSAS, CONEXAS CON EL BANDOLERISMO Y ENCAMINADAS A SEGUIR CONSERVANDO SU PODER POLITICO Y ECONOMICO) VA A SER OBJETO DE UNA FUERTE REPRESION, SO CAPA DE RESTAURAR EL ORDEN PUBLICO. TODO ELLO EN UNOS MOMENTOS GRAVES PARA LA CORONA: LA GUERRA DE CATALUÑA, PARA LA QUE SE NECESITABA UNA INCONDICIONAL AYUDA VALENCIANA Y POR TANTO UNA SITUACION INTERNA DE PROBLEMAS Y RESISTENCIAS.
Towards CEP stable sub two cycle IR pulse compression with bulk material
2010
We demonstrate both experimentally and numerically that self-steepening during propagation in a hollow-fiber followed by linear propagation through glass in the anomalous dispersion enables pulse compression down to 1.9 cycles at 1.8 micron wavelength.
Amplifier similariton fibre laser with nonlinear spectral compression
2012
We propose and numerically demonstrate a new concept of fibre laser architecture supporting self-similar pulse evolution in the amplifier and nonlinear pulse spectral compression in the passive fibre. The latter process is beneficial for improving the power efficiency as it prevents strong spectral filtering from being highly dissipative.
Broadband dispersion compensation using inner cladding modes in photonic crystal fibers.
2012
A photonic crystal fiber is optimized for chromatic dispersion compensation by using inner cladding modes. To this end, a photonic-oriented version of the downhill-simplex algorithm is employed. The numerical results show a dispersion profile that accurately compensates the targeted dispersion curve, as well as its dispersion slope. The presented fiber has a simple structure, while radiation losses can be reduced simply by adding a few more air-hole rings. Fabrication tolerances are also considered showing how fabrication inaccuracies effects can be overridden by just adjusting the compensation length.
Acousto-optic interaction in biconical tapered fibers: shaping of the stopbands
2016
The effect of a gradual reduction of the fiber diameter on the acousto-optic (AO) interaction is reported. The experimental and theoretical study of the intermodal coupling induced by a flexural acoustic wave in a biconical tapered fiber shows that it is possible to shape the transmission spectrum, for example, substantially broadening the bandwidth of the resonant couplings. The geometry of the taper transitions can be regarded as an extra degree of freedom to design the AO devices. Optical bandwidths above 45 nm are reported in a tapered fiber with a gradual reduction of the fiber down to 70 μm diameter. The effect of including long taper transition is also reported in a double-tapered st…
Oligonucleotide-Hybridization Fiber-Optic Biosensor using a Narrow Bandwidth Long Period Grating
2017
Nanometric narrowband Long Period Gratings (LPG) are investigated for the implementation of improved fiber optic biosensors. The reduction of more than one order of magnitude in the linewidth of the LPG with respect standard LPG at 1500 nm, leads to the improvement of the resolution of the sensor. By selecting the proper fabrication parameters (high numerical aperture, relatively high order mode and large length), LPGs with a 3-dB bandwidth of 1.5 nm were fabricated. The sensitivity of the LPG as a refractometer was calculated, and experimentally characterized in detail. In particular, the LP0,17 and LP0,18 resonances were investigated, in order to select the most suitable one for the bioex…
