Partially-supervised Mention Detection

open access: yes, 2019
Learning to detect entity mentions without using syntactic information can be useful for integration and joint optimization with other tasks. However, it is common to have partially annotated data for this problem. Here, we investigate two approaches to deal with partial annotation of mentions: weighted loss and soft-target classification.

A Local Detection Approach for Named Entity Recognition and Mention Detection [PDF]

open access: yesProceedings of the 55th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers), 2017
In this paper, we study a novel approach for named entity recognition (NER) and mention detection (MD) in natural language processing. Instead of treating NER as a sequence labeling problem, we propose a new local detection approach, which relies on the recent fixed-size ordinally forgetting encoding (FOFE) method to fully encode each sentence fragment

Highly Sensitive Electrochemical Detection of Azithromycin with Graphene-Modified Electrode

open access: yesSensors, 2022
An electrochemical cell containing two graphite rods was filled with the appropriate electrolyte (0.2 M ammonia + 0.2 M ammonium sulphate) and connected to the exfoliation system to synthesize graphene (EGr).

Angina de peito. Isquemia silenciosa.

open access: yesActa Médica Portuguesa, 1997
One of the most difficult problems related to coronary artery disease is the detection and eventual treatment of silent myocardial ischemia (SMI). After defining the concept of SMI and total ischemia burden, the author approaches the pathophysiology of ...

Designing and fabrication of electrochemical nano-biosensor for the fast detection of SARS-CoV-2-RNA

open access: yesScientific Reports, 2023
SARS-CoV-2 caused a global panic among populations. Rapid diagnostic procedures for the virus are crucial for disease control. Thus, the designed signature probe from a highly conserved region of the virus was chemically immobilized onto the ...

Use Generalized Representations, But Do Not Forget Surface Features [PDF]

open access: yes, 2017
Only a year ago, all state-of-the-art coreference resolvers were using an extensive amount of surface features. Recently, there was a paradigm shift towards using word embeddings and deep neural networks, where the use of surface features is very limited.

A New Efficient Multi-Object Detection and Size Calculation for Blended Tobacco Shreds Using an Improved YOLOv7 Network and LWC Algorithm

open access: yesSensors, 2023
Detection of the four tobacco shred varieties and the subsequent unbroken tobacco shred rate are the primary tasks in cigarette inspection lines. It is especially critical to identify both single and overlapped tobacco shreds at one time, that is, fast ...

A flexible low-cost, high-precision, single interface electrical impedance tomography system for breast cancer detection using FPGA [PDF]

open access: yes, 2010
Typically, in multi-frequency Electrical Impedance Tomography (EIT) systems, a current is applied and the voltages developed across the subject are detected.

Supermassive black holes or boson stars? Hair counting with gravitational wave detectors [PDF]

open access: yes, 2006
The evidence for supermassive Kerr black holes in galactic centers is strong and growing, but only the detection of gravitational waves will convincingly rule out other possibilities to explain the observations. The Kerr spacetime is completely specified
