The Pollen Reference Collection of LPP – UNIMORE
No full textThe Pollen Reference Collection of the Laboratory of Palynology and Palaeobotany (LPP) of the University of Modena and Reggio Emilia is titled to Daria Bertolani Marchetti who carried out to Modena the first slides in 1989. The Reference Collection is organized in the following sections: 1) Envelopes, with pollen from plant material collected in the field or from herbarium sheets, are 3098, and refer to about 1100 different species. 2) Microtubes, contain acetolysed pollen preserved in glycerol jelly, and are about 1440. 3) Slides are mounted with acetolysed and fresh pollen. Therefore, the pollen collection can be used for paleopalynology and actuopalynology. The slides, put into boxes slide rack, are classified according to the morphological criterion (NPC = Number - Position - Character of the apertures - Erdtman, 1969). Their number is about 2000.
In the Reference Collection there are three sections: Reference Collection, containing the reference material, described above; Research Collection, relating to materials and sites studied in the laboratory (ca. 22,000 slides); Educational Collection, containing two types of reference slides: slides with the pollen of a single species and “mixed slides” with more species with the same aperture type, number and position, set up to facilitate the distinction of similar pollen. The Educational Collection includes selected slides with material from research work, e.g. archaeological sites, lake/fluvial sediments, forensic cases, honeys, plant systematics.
The use of the collection has been recently improved by a database designated by F. Torri and P. Torri, to search the reference material by taxonomic criteria and/or morphological characteristics. Users can search the database according to a single criterion or a combination of morphological characteristics commonly used to visually identify pollen: aperture, exine ornamentation, size range. Images of the pollen will be associated to relevant species

Comparative analysis of different endovascular modalities to treat splenic artery aneurysms
No full textBACKGROUND: Endovascular treatment of splenic artery aneurysms (SAAs) is widely applied in the current clinical practice. The aim of this paper was to describe our single center experience on endovascular treatment of SAAs, comparing the outcomes obtained with two different METHODS: Between January 2010 and December 2021, 35 patients with certain diagnosis of non-ruptured SAA were admitted to our center. Twenty-eight patients treated with packing or sandwich techniques were included in the study analysis. Primary outcome measures analyzed were 30-day mortality and mean hospital stay. Secondary outcome measures analyzed were freedom from splenectomy, and the rate of postembolization syndrome. Chi-square test was used to compare the two endovascular techniques. Statistical significance was defined as P value <0.05. RESULTS: The mean age was 56.5 +/- 12.8 years. Most of patients were females (22, 78.6%). Eighteen patients underwent sandwich technique (Group A), and the remaining 10 packing technique (Group B). Technical success was 100%. Intraoperative and 30-day mortality were 0 in both groups. Mean hospital stay was 4.2 +/- 4.0 days in Group A, and 2.3 +/- 3.9 days in Group B (P=0.93). Postembolization syndrome occurred in 9 cases (50%) in Group A, and in 4 cases (40%) in Group B (P=0.521). Only one patient in Group A (5.5%) required splenectomy (P=0.392). CONCLUSIONS: Packing and sandwich techniques seem to be similarly safe and effective in treating SAAs and have no statistically significant differences in terms of early mortality and morbidity.

Polimi at CLinkaRT: a Conditional Random Field vs a BERT-based approach
No full textIn the context of the EVALITA 2023 challenge, we present the models we have developed for the CLinkaRT task, which aims to identify medical examinations and their corresponding results in Italian clinical documents. We propose two distinct approaches: one utilising a Conditional Random Field (CRF), a probabilistic graphical model traditionally used for Named Entity Recognition, and the other based on BERT, the transformer-based model that is currently state-of-the-art for many Natural Language Processing tasks. Both models incorporate external knowledge from publicly available medical resources and are enhanced with heuristic rules to establish associations between exams and results. Our comparative analysis elects the CRF-based model as the winner, securing the third position in the competition ranking, but the BERT-based model demonstrated competitive performance
Caratterizzazione dinamica di torri medioevali ravennati
No full textNel presente contributo si riportano gli esiti delle prove effettuate su due torri medievali ravennati: il campanile di S. Apollinare in Classe (della omonima frazione) e quello di S. Maria in Fabriago (nella Frazione di Campanile del comune di Lugo). Lo studio per la caratterizzazione dinamica è stato preceduto da un accurato rilievo tecnico - costruttivo delle strutture, nonché dall’esecuzione di specifiche indagini geofisiche nel terreno circostante. Le prove dinamiche sono state eseguite utilizzando come sorgenti di eccitazione sia l’oscillazione delle campane sia urti provocati a diverse altezze della torre; il rilievo della risposta è stato effettuato tramite accelerometri posizionati in diversi punti della struttura. L’analisi dei dati registrati ha permesso di ottenere i parametri modali dei campanili. Inoltre, al fine di determinare il profilo delle velocità delle onde di taglio del suolo ed ottenere un modello dettagliato ed affidabile della geologia locale, sono state eseguite misure in situ di rumore ambientale utilizzando il metodo Re.Mi. (Refraction Micro-tremors). Allo scopo di formulare un modello numerico delle torri in buon accordo con i risultati sperimentali, sono stati messi a punto differenti modelli agli elementi finiti delle strutture in esame, tenendo conto anche dell’effetto dell’interazione terreno struttura. Tali modelli costituiscono la base per l’analisi sismica delle torri oggetto d’indagine
