Fostering the Ecosystem of Open Neural Encoders for Portuguese with Albertina P...

To foster the neural encoding of Portuguese, this paper contributes foundation encoder models that represent an expansion of the still very scarce ecosystem of large language models specifically developed for this language that are fully open, in the sense that they are open source and openly distributed for free under an open license for any purpose, thus including research and commercial usages. Like most lan...

PORTULAN ExtraGLUE Datasets and Models: Kick-starting a Benchmark for the Neura...

Leveraging research on the neural modelling of Portuguese, we contribute a collection of datasets for an array of language processing tasks and a corresponding collection of fine-tuned neural language models on these downstream tasks. To align with mainstream benchmarks in the literature, originally developed in English, and to kick start their Portuguese counterparts, the datasets were machine-translated from ...

Advancing Neural Encoding of Portuguese with Transformer Albertina PT-*

To advance the neural encoding of Portuguese (PT), and a fortiori the technological preparation of this language for the digital age, we developed a Transformer-based foundation model that sets a new state of the art in this respect for two of its variants, namely European Portuguese from Portugal (PT-PT) and American Portuguese from Brazil (PT-BR). To develop this encoder, which we named Albertina PT-*, a stro...

Quality control of vagotomy in duodenal ulcer perforation.

The efficacy of truncal vagotomy combined with pyloroplasty has been studied in 56 patients, divided into the following groups: Group I-29 patients submitted to bilateral truncal vagotomy (BTV) and pyloroplasty, as the method of treatment to solve the problem of perforated duodenal ulcer (initial and retrospective phase of study). Group II-With 11 patients, who underwent the same operation as those in Group I b...

Surgical therapy of peptic stenosis of the esophagus in adults.

One hundred and one patients with reflux esophagitis and strictures, submitted to different kinds of surgical solutions over the last 16 years, were revised. Seventy seven patients had dilatable stricture and the lower esophageal sphincter mechanism could be brought intra-abdominally in 70. In 36 there was radiographic evidence of hiatal hernia and 8 had a Barrett esophagus. The surgical technique employed in t...

Preservation of the liver using a new solution of phosphate-buffered saccharose.

The efficacy of the new phosphate-buffered sucrose solution (PBS), was compared with the conventional Euro-Collins (EC) and the lactated Ringer solution (LR), in its capacity to preserve the canine liver in cold storage. Three groups of 6 canine livers, each group in one of those solutions, were put in cold storage for 24 h at 4 degrees centigrade. At the end of this period the effect of warm hepatic reperfusio...

Total gastrectomy with creation of a new stomach using the jejunum. A retrospec...

Results obtained in 120 patients with gastric carcinoma, and submitted between 1982 and 1989, to a total gastrectomy and a new technique of reconstruction with jejunum, are analyzed retrospectively. This technique associates, a jejunoplication around the terminal esophagus with the purpose to eliminate the entero-esophageal reflux and the risk of dehiscence, and a double jejuno-jejunostomy with the target to de...
