Small Sample Biometric Recognition Based on Palmprint and Face Fusion

2009

Contactless biometrics provide high comfort and hygiene in person recognition. Because of this, such systems are better accepted by the general public. This paper proposes an adaptive, contactless, biometric system which combines two modalities: palmprint and face. The processing chain has been designed to overcome embedded system constraints and small sample set problem: after a palmprint is extracted from a hand image, Gabor filters are applied to both the palmprint and face in order to extract parameters, which are then used for classification. Fusion possibilities are also discussed and tested using a multimodal database of 130 people designed by the authors. High recognition performanc…

A Magnetic Resonance Imaging–Based Prediction Model for Prostate Biopsy Risk Stratification

2018

IMPORTANCE: Multiparametric magnetic resonance imaging (MRI) in conjunction with MRI–transrectal ultrasound (TRUS) fusion-guided biopsies have improved the detection of prostate cancer. It is unclear whether MRI itself adds additional value to multivariable prediction models based on clinical parameters. OBJECTIVE: To determine whether an MRI-based prediction model can reduce unnecessary biopsies in patients with suspected prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Patients underwent MRI, MRI-TRUS fusion-guided biopsy, and 12-core systematic biopsy in 1 session. The development cohort used to derive the prediction model consisted of 400 patients from 1 institution enrolled between …

Acetic acid compared with i-scan imaging for detecting Barrett's esophagus: a randomized, comparative trial.

2013

Background Traditional surveillance in patients with Barrett's esophagus (BE) has relied on random biopsies. Targeted biopsies that use advanced imaging modalities may significantly improve detection of specialized columnar epithelium (SCE). Objective We compared the efficacy of targeted biopsies that used i -scan or acetic acid to random biopsies in the detection of SCE. Design Patients with visible columnar lined epithelium or known BE were randomized at a 1:1 ratio to undergo acetic acid application or i -scan with targeted biopsies. Setting Targeted biopsies were performed based on surface architecture according to the Guelrud classification followed by 4-quadrant biopsies. Patients A t…

Reproduction beyond cancer: A message of hope for young women

2006

Abstract Objective. Aggressive chemotherapy and radiotherapy or radical oncological surgery in young women with cancer has greatly enhanced these patients' life expectancy, but these treatments often cause infertility or premature ovarian failure due to a massive destruction of the ovarian reserve. The objective of this review is to discuss the effect of the various cancer treatments on fertility and present the various fertility sparing operations and fertility preservation strategies. Method. An extensive survey of the most up-to-date literature was performed. Results. This review discusses the impact of current cancer treatment on fertility potential and the various surgical and assisted…

A comprehensive use of ultrasound examination in infertility workup

2021

Considering the growing availability of ultrasound diagnostic methods in gynecology, its role in the infertility setting is increasing. In this review, we present an up-to-date ultrasound based diagnostic scheme in infertility workup comprising the evaluation of ovarian anatomy and function, uterine exploration, as well as tubal patency. The possibility of performing the vast majority of infertility diagnostics by ultrasound in the ambulatory settings is not only attractive and beneficial to patients, but also to health care system. Thus, it is vital for gynecologists to implement modern non-invasive ultrasound modalities in their everyday practice.

Congenital Müllerian anomalies: a review of currently available imaging modalities

2002

Congenital uterine anomalies are associated with infertility and adverse obstetric outcomes. The sensitivity of transvaginal sonography in diagnosing these anomalies ranges from 42% to 87%. More re...

The keyboard as a part of visual, auditory and kinesthetic processing in sight-reading at the piano

2009

Sight-reading at the piano requires coordination of multiple modalities—visual, auditory, and kinesthetic. Visual feedback (obtained by looking at the keyboard and the fingers) is usually regarded as one means by which pianists guide musical performance, but few researchers have focused on the organisational aspects implicit in the information provided by the keyboard. This study investigated the role of the keyboard with respect to the visual, auditory, and kinesthetic modalities involved in sight-reading. Five pianists sight-read two compositions, each in a different musical style. They were then interviewed in a semi-structured interview format. A qualitative content analysis was made fr…

Textos de Identidad Multimodales en el Aula de Inglés como Lengua Extranjera: Una Herramienta para Desarrollo de Habilidades Cognitivas y Académicas …

2016

[EN] The present action-research project in progress deals with the production and evaluation of “identity texts” (Cummins & Early, 2011) from EFL students in the context of a specific subject within the major of English Teacher in Primary Education at the Faculty of Education of the Universitat de València. This project is part of a larger “Innovation in education” project, whose main objective is to promote the use of identity texts as the key strategy of the “teaching for linguistic transfer” approach (Cummins, 2005b). Identity texts foster learners’ cognitive and academic transfer from their first language (L1) to their second or foreign language (L2/FL), and offer students an opportuni…
