On estimating the center frequency of ultrasonic pulses.

Ultrasonics

Vergara L, Gosálbez J, Miralles R, Bosch I.
PMID: 15047389
Ultrasonics. 2004 Apr;42(1):813-8. doi: 10.1016/j.ultras.2004.01.057.

In this paper we propose a new technique for estimating the center frequency of the ultrasound pulse from records of backscattering noise. We start by considering that the conventional maximum frequency method can be seen as a filtering (differentiator)...

Gle1 Regulates RNA Binding of the DEAD-Box Helicase Ded1 in Its Complex Role in Translation Initiation.

Molecular and cellular biology

Aryanpur PP, Regan CA, Collins JM, Mittelmeier TM, Renner DM, Vergara AM, Brown NP, Bolger TA.
PMID: 28784717
Mol Cell Biol. 2017 Oct 13;37(21). doi: 10.1128/MCB.00139-17. Print 2017 Nov 01.

DEAD-box proteins (DBPs) are required in gene expression to facilitate changes to ribonucleoprotein complexes, but the cellular mechanisms and regulation of DBPs are not fully defined. Gle1 is a multifunctional regulator of DBPs with roles in mRNA export and...

Effectiveness of Culturally Appropriate Adaptations to Juvenile Justice Services.

Journal of juvenile justice

Vergara AT, Kathuria P, Woodmass K, Janke R, Wells SJ.
PMID: 29468092
J Juv Justice. 2016;5(2):85-103.

Despite efforts to increase cultural competence of services within juvenile justice systems, disproportional minority contact (DMC) persists throughout Canada and the United States. Commonly cited approaches to decreasing DMC include large-scale systemic changes as well as enhancement of the...

Multiclass Alpha Integration of Scores from Multiple Classifiers.

Neural computation

Safont G, Salazar A, Vergara L.
PMID: 30764745
Neural Comput. 2019 Apr;31(4):806-825. doi: 10.1162/neco_a_01169. Epub 2019 Feb 14.

Alpha integration methods have been used for integrating stochastic models and fusion in the context of detection (binary classification). Our work proposes separated score integration (SSI), a new method based on alpha integration to perform soft fusion of scores...

Growth and sculpting of Co nano-strings on Si micro-cantilevers: magneto-mechanical properties.

Nanotechnology

Madurga V, Favieres C, Vergara J.
PMID: 20124658
Nanotechnology. 2010 Mar 05;21(9):095702. doi: 10.1088/0957-4484/21/9/095702. Epub 2010 Feb 03.

Si micro-cantilevers were coated with Co nano-strings, which were simultaneously grown and sculpted during off-normal pulsed laser deposition. The surface morphology of micro-cantilevers with longitudinal or transverse nano-strings was analysed by scanning tunnelling microscopy. Magnetic anisotropy was detected with...

Generating and measuring the anisotropic elastic behaviour of Co thin films with oriented surface nano-strings on micro-cantilevers.

Nanoscale research letters

Madurga V, Vergara J, Favieres C.
PMID: 21711815
Nanoscale Res Lett. 2011 Apr 12;6(1):325. doi: 10.1186/1556-276X-6-325.

In this research, the elastic behaviour of two Co thin films simultaneously deposited in an off-normal angle method was studied. Towards this end, two Si micro-cantilevers were simultaneously coated using pulsed laser deposition at an oblique angle, creating a...

Endobronchial administration of tranexamic Acid for controlling pulmonary bleeding: a pilot study.

Journal of bronchology & interventional pulmonology

Márquez-Martín E, Vergara DG, Martín-Juan J, Flacón AR, Lopez-Campos JL, Rodríguez-Panadero F.
PMID: 23168726
J Bronchology Interv Pulmonol. 2010 Apr;17(2):122-5. doi: 10.1097/LBR.0b013e3181dc8c17.

BACKGROUND: Tranexamic acid (TA) is a synthetic antifibrinolytic substance used for short-term control of bleeding. However, control of pulmonary bleeding with endobronchial administration of TA in more than 2 cases has not been attempted earlier.OBJECTIVE: We tested the feasibility...

Blind detection of nonlinearities in multiple-echo ultrasonic signals.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Miralles R, Vergara L, Salazar A, Igual J.
PMID: 18407853
IEEE Trans Ultrason Ferroelectr Freq Control. 2008 Mar;55(3):637-47. doi: 10.1109/TUFFC.2008.688.

In this paper, we propose and analyze by means of simulations the use of surrogate data algorithms for blind detection of nonlinearities in multiple-echo ultrasonic signals. We assume a blind scheme so that no information about the input (emitted...
