Zero-shot learning for clinical phenotyping: comparing LLMs and rule-based methods

Background: Phenotyping, the process of systematically identifying and classifying conditions within clinical data, is a crucial first step in any data science work involving Electronic Health Records (EHRs). Traditional approaches require extensive manual annotation efforts and face challenges with scalability. Methods: We investigated the use of Large Language Models (LLMs) for zero-shot phenotyping of 20 pre...

Morphology of the dentin–resin interface yielded by twostep etch-and-rinse adhe...

Aim: The study aimed to analyze the morphology of the dentin– resin interface yielded by two-step etch-and-rinse adhesive systems with different solvents and compositions. Materials and methods: A total of 32 dentine disks were prepared and randomly assigned to four groups of one-bottle etchand- rinse adhesive systems containing different solvents: group I, Adper Scotchbond-1XT™ (ethanol/water); group II, XP-Bo...

Ten years of hospital admissions for liver cirrhosis in Portugal

Background and aims More data on epidemiology of liver diseases in Europe are needed. We aimed to characterize hospital admissions for liver cirrhosis in Portugal during the past decade. Patients and methods We analyzed all hospital admissions for cirrhosis in Portugal Mainland between 2003 and 2012 registered in the national Diagnosis-Related Group database. Cirrhosis was classified according to etiology consi...

Influence of different solvents on the morphology of the hybrid layer using two...

To evaluate if different etch-and-rinse adhesive solvents influenced the hybrid layer’s morphology. Four one-bottle etch-and-rinse adhesive systems containing different solvents—Group A: Scotchbond 1XTTM– 3M ESPE, Group B: XP – BondTM – Dentsply, Group C: Prime&Bond NT1 – Dentply, and Group D: One Coat Bond1 - Colte`ne Whaledent—were applied onto 32 dentin discs which were thermocycled, prepared, and examined u...

Safe use of ozone gas in enamel adhesion

Purpose: Evaluate the shear bond strength of a self-etching system to enamel pretreated with ozone and its type of fracture. Matherial and methods: Thirty sound bovine incisors were bisected and polished just before the application of the adhesive system. The adhesion area was limited to a 3-mm diameter. The specimens were randomly assigned to the experimental groups (n = 15) and composite resin cylinders were ...

Automatic Expansion of a Social Judgment Lexicon for Sentiment Analysis

We present a new method for automatically enlarging a sentiment lexicon for mining social judgments from text, i.e., extracting opinions about human subjects. We use a two-step approach: first, we find which adjectives can be used as human modifiers, and then we assign their polarity attribute. To identify the human modifiers, we developed a set of hand-crafted lexico-syntactic rules representing elementary cop...

The Geo-Net-PT/Yahoo! GeoPlanet (TM) concordance

Background: Geo-Net-PT is a geospatial ontology representing the Portuguese territory and the relations between the several locations within in. Yahoo! GeoPlanet (TM) is a geospatial ontology that covers the whole world. To diminish the effects of repeated information, we propose an alignment between the administrative part of these two ontologies based on name similarity and physical closeness. Results: After ...

Geographic Ontologies Production in GREASE-II

This report presents the development of authoritative geographic knowledge and related conceptualization tools in the project GREASE-II. The feature concept, an abstraction for geographical entities, is the centre of the conceptual model, which is oriented towards a representation of geographic data as interlinked web resources. The conceptualization tools are the Geographic Knowledge Base (GKB) system (version...
