Antístenes y la prehistoria de la noción de campo semántico
Authors: Márisco Claudia T. 
Published: October 2019

Entre la filosofía platónica y los análisis sofísticos acerca del lenguaje, se encuentra una teoría potente y atípica que propone fundamentar el conocimiento de lo real a partir de un análisis lingüístico de tipo semántico, que permitiría también resolver el problema del fundamento de la ética sin recurrir a un radicalismo ontológico. Nos referimos a la filosofía de Antístenes, que examinaremos en tanto antecedente clásico de la moderna noción de campo semántico, con atención a testimonios que permiten entrever los ejes de la teoría: investigación de los nombres (ἐπίσκεψις ὀνομάτων), uso de los nombres (χρῆσις ὀνομάτων) y distinción en géneros (διαλέγειν κατὰ γένη).
Pseudepicharmea: Alle origini di un corpus pseudepigrafo
Authors: Álvarez Salas Omar 
Published: October 2019

In questo studio si prende in esame la tradizione riguardante le opere pseudepigrafe attribuite nell’Antichità al comico siciliano Epicarmo, che fu ben noto per la sua spiccata propensione alla formulazione di pensieri sentenziosi ed alla escogitazione di sofisticati espedienti comici. Attraverso un’analisi particolareggiata delle testimonianze sugli scritti pseudepicarmei e su altri corpora affini, si giunge a stabilire qui uno stringente parallelismo tra la produzione di essi e quella degli Pseudopythagorica; su questa base, si tenta poi di ricostruire storicamente lo sviluppo degli Pseudepicharmea, di cui (in contrasto con tentativi precedenti) si propone una collocazione cronologica più congrua con il carattere linguistico e contenutistico attestato per tali opere. A modo di chiusura, si cerca di illustrare il meccanismo che, forse prendendo avvio da sentenze autentiche estrapolate da commedie di Epicarmo, avrebbe portato alla costituzione di un gnomologio pseudepicarmeo.

Stemich, Martina, <i>Parmenides’ Einübung in die Seinserkenntnis</i>, Frankfurt, Ontos Verlag, 2008

Published: October 2019

La morte prematura non consentirà a Martina Stemich (1957-2005) di sviluppare ulteriormente il progetto di ricerca articolato, sin dalla metà degli anni novanta, nel suo saggio su Eraclito (Martina Stemich Huber, Heraklit. Der Werdegang des Weisen, 1996) e ripreso in questa Habilitationsschrift pubblicata postuma: dimostrare come, già nella tradizione presocratica —un paio di secoli prima che il modello si affermasse nella cultura ellenistica—, si fosse delineata l’idea della filosofia come sistematica indagine intorno alle posibilita della conoscenza umana e come ordinata formazione spirituale. In questa prospettiva, l’indirizzo della analisi insiste sulla “teoria dell’apprendimento” (Lerntheorie) di Parmenide, in altre parole sulla rappresentazione —all’interno del poema Peri physeōs interpretato come esercizio didattico-dottrinale (Lehrgedicht)— dell’avviamento del kouros al pensiero filosofico.

Published: October 2019

Del 8 al 12 de septiembre de 2008 se dieron cita en la Universidad Nacional Autónoma de México, especialistas en filología clásica procedentes de diversos países para celebrar el II Congreso Internacional de Estudios Clásicos en México. “La Antigüedad Clásica: alcances interdisciplinarios de su estudio actual”. El Congreso, cuya organización estuvo a cargo del Centro de Estudios Clásicos del Instituto de Investigaciones Filológicas y del Colegio de Letras Clásicas de la Facultad de Filosofía y Letras, superó las expectativas, no sólo por la calidad de los trabajos presentados, sino también por la interacción que se dio entre académicos y alumnos de la UNAM y los especialistas de otras latitudes, en una vinculación que tuvo como centro la interdisciplina, hilo conductor del Congreso.
Ceremonia de instalación de cursos 2009-1 del colegio de Letras Clásicas
Authors: Belmonte Trujado Carlos 
Published: October 2019

Poco a poco empieza a sazonarse la buena costumbre de celebrar la instalación de cursos del Colegio de Letras Clásicas. La ceremonia siempre se ha dedicado a la nueva generación de alumnos, esta vez a la de 2009, en el Aula Magna “Fray Alonso de la Vera Cruz” de la Facultad de Filosofía y Letras. Además de los ponentes que enseguida referiré, asistieron alumnos de varios semestres y algunos profesores de la carrera, mas lo paradójico de la bienvenida fue que los alumnos de nuevo ingreso (por una involuntaria confusión) no escucharon el discurso y la música que se habían preparado para ellos. Por tanto considero que es útil para los noveles estudiantes de Letras Clásicas dar noticia de las palabras de los participantes y reproducir en parte la Relectio que se pronunció.
Eleatica 2008-2009
Authors: Gambetti Francesca 
Published: October 2019

Dal 15 al 18 gennaio 2009, nel prestigioso Complesso Alario di Ascea (Salerno), si è svolto l’ormai consueto appuntamento annuale di Eleatica, dal titolo “Zenone e l’infinito”, sotto la salda direzione scientifica del Prof. Livio Rossetti dell’Università di Perugia. Quest’anno le tre lezioni magistrali sono state tenute dal Prof. Jonathan Barnes dell’Université de Paris IV-Sorbonne, che ha cercato, in perfetto stile eleatico, di interpretare i famosi paradossi zenoniani attraverso una chiave di lettura veramente paradossale rispetto alla storiografia corrente, sostenendo che 1) se vogliamo comprendere i paradossi di Zenone dobbiamo rimanere sul piano strettamente fisico, e quindi 2) la matematica non è in grado di risolvere gli stessi; 3) sul piano logico generale, non è vero che Zenone usa il termine infinito come se si trattasse del nome di un numero.

Una leyenda tseltal: El infierno o K'atimbak (Calentar conhuesos)
Authors: Maurer Ávalos Eugenio , Guzmán Avelino 
Published: October 2019

In a distant past, say our mothers and fathers (ancestors), there was a Tseltal couple. Husband and wife loved each other deeply. They were very poor but, nevertheless the woman brought home exquisite meals every day. One day she died; and the husband, who cried sadly in the fields, was invited by a ladino horseman (the devil) to ride with him to the place where his wife lived (hell, or k'atimbak in Tseltal: warming with bones). When they got there, the man was asked by the ladino to bring some firewood (bones) and was given a mule to carry it. When he hit her because she did not want to walk, the mule started speaking to him. (By her way of speaking he recognized his wife.) She told him that he was also guilty because he accepted the goods she used to bring home, without asking her where she got them. She invited him to lunch and they ate worms, to which the woman was already accustomed. The man was given some iron sandals (huaraches) which he should wear out before being allowed to go back to the world. This did not take him long because, advised by his mule-wife, he rubbed them in her urine. Before leaving, he received a message from his wife to be carried to the world: people should not do what they themselves (husband and wife) had done. The man died soon after, but there is nobody to tell us if he went back to hell and met his wife again, or if he went somewhere else.

siyasal iletişim için sosyal ağların etkin ve doğru bir biçimde kullanılması
büyük önem taşımaktadır. Bu bağlamda siyasi aktörler sosyal ağlardaki kişisel
hesaplarını kendi aday imajlarını oluşturmada ve seçmenlerle etkileşim kurmakta
kullanmaktadırlar. Instagram’da Türkiye her gün artan kullanıcı sayısı ve
kullanım sıklığı açısından çevrimiçi siyasal iletişimdeki sosyal ağların en
önemlilerinden biridir. Bu çalışmada, siyasal liderlerin Instagram hesaplarını
nasıl ve ne derece etkin kullandıklarının ortaya çıkarılması amaçlanmıştır. Bu
doğrultuda iktidar ve ana muhalefet liderleri olan Recep Tayyip Erdoğan ve

Towards a SLAM-based augmented reality application for the 3D annotation of rock art
Authors: Abergel Violette , Jacquot Kévin , De Luca Livio , Veron Philippe 
Published: October 2019

The digital technologies developed in recent decades have considerably enriched the survey and documentation practices in the field of cultural heritage. They now raise new issues and challenges, particularly in the management of multidimensional datasets, which require the development of new methods for the analysis, interpretation and sharing of heterogeneous data. In the case of rock art sites, additional challenges are added to this context, due to their nature and fragility. In many cases, digital data alone is not sufficient to meet contextualization, analysis or traceability needs.
In this context, we propose to develop an application dedicated to rock art survey, allowing 3D annotation in augmented reality. This work is a part of an ongoing project about an information system dedicated to cultural heritage documentation. For this purpose, we propose a registration method based on a spatial resection calculation. We will also raise the perspectives that this opens up for heritage survey and documentation, in particular in terms of visualization enhancement.
3D Objects based Security in Virtual and Augmented Reality Systems
Authors: Djaghloul Haroun , Jessel Jean-Pierre 
Published: October 2019

This paper presents a new method for public and blind watermarking of 3D objects and hiding information of various types in virtual reality and augmented reality environments. In particular, the virtual scene is transformed to a tree-based model using constructive solid geometry (CSG). The tree of the virtual 3D objects is composed of nodes and leafs. Each tree node contains a set operator (union, intersection or difference) whereas the tree leafs consist of geometric primitives such as spheres, cylinders and cubes. The proposed method allows embedding invisible watermarks that can hide different security information types. The proposed method ensures unlimited capacity and absolute invisibility of the hidden information with robustness to affine transformations. Thanks to these unique properties, it is possible to implement all the security infrastructures needed for a virtual and augmented reality system. Finally, the performances of the proposed method are shown using 3D models of different types and scenes.
Polymer-Based Sealing Materials as Cement Alternative to Restore Wellbore Isolation
Authors: Ziashahabi Pouya , Ravi Kris , Prohaska Michael 
Published: October 2019

Abstract
Well integrity is one of the main issues during all life cycles of the well and if any barrier element fails and compromise the integrity of well, remedial strategy may have to be performed to restore the safety and economics of the well. Cement is conventionally used as the isolation material in remedial and primary jobs. However, due to several inherent limitations in cement characteristics, such as cement shrinkage or poor cement slurry compatibility with downhole fluids, it is not always the best solution. Besides, cement slurry is a particle laden fluid which prevents it penetrating in to tight cracks/pathways to ensure isolation during remedial treatments.
This project illustrates the effort to develop a customized polymer system as cement alternative addressing several challenges posed by conventional materials and experimental studies are designed to evaluate its characteristics such as rheology, injectivity and mechanical properties. Furthermore, the compatibility of these systems with drilling fluids contamination and shrinkage behaviour upon cure are evaluated. Afterward, based on the results of measurements, the limitations of each system are determined and the best formulation is optimized.
The results of experiments prove that beside the appropriate rheological properties, the system provides excellent mechanical properties and much lower shrinkage rate upon cure compared to cement. The system withstands and maintains its properties after being contaminated with considerable volume of downhole fluids such as drilling fluids and hydrocarbons and mechanical properties such as compressive strength is not much affected by contamination.
The unique characteristics of customized sealing system as cement alternative could provide benefits to industry by solving several current challenges in achieving secure isolation. Particularly due its ability to penetrate in to tight cracks, this system affords an effective method to mitigate sustained casing pressure or as a remedial solution for casing leakages which cannot be achieved easily by conventional methods.
Predicting the Amount of Lost Circulation While Drilling Using Artificial Neural Networks: An Example of Southern Iraq Oil Fields
Authors: Abbas Ahmed K. , Hamed Hussain M. , Al-Bazzaz Waleed , Abbas Hayder 
Published: October 2019

Abstract
Lost circulation is a serious problem that imposes some extra costs to petroleum and gas exploration operations. Substantial technical and economic benefits can be accomplished if the severity and frequency of mud loss are considered during the well planning procedure. This will lead to preventing the occurrence of losses by using treatments/solutions that are applied before entering lost circulation zones. In the present work, new models were developed to predict the amount of lost circulation using artificial neural networks (ANNs). This model was implemented to obtain a deeper understanding of the relations between the losses rate and the controllable drilling variables (i.e., rate of penetration [ROP], flow rate [FR], circulation pressure [CP], weight on bit [WOB], and rotation per minute [RPM]). The losses rate was found to be sensitive to high ROP, FR, and CP, such that increasing these parameters continuously increase the amount of lost circulation. While a slight rise in the losses rate was observed at high WOB and RPM. The proposed ANNs model was used to predict the losses rate for two wells, and comparison plot (actual amount of lost circulation versus predicted) was introduced as a function of depth. An accurate and early prediction of lost circulation has been of great importance to avoid the risks associated with this problem's occurrence.
TIMP-2 secreted by monocytes is a potent suppressor of invadopodia formation in pancreatic cancer cells

Published: October 2019

Abstract
Background Monocytes are a major component of the tumor microenvironment (TME) in pancreatic ductal adenocarcinoma (PDAC). However, the complex interactions between tumor cells and monocytes and their role in tumor invasion have not been fully established. Methods In this in vitro study, to specifically test the impact of interaction on invasive potential, two PDAC cell lines PaTu8902 and CFPAC-1 were selected on their ability to form invasive adhesions, otherwise known as invadopodia. Co-culture experiments were performed using undifferentiated THP1 monocytes. Results When the PDAC cells were co-cultured with undifferentiated THP1 monocytes invadopodia formation was significantly suppressed. Moreover, conditioned media of THP1 cells (CM) was also able to suppress invadopodia formation. Further investigation revealed that both tissue inhibitor of metalloproteinase (TIMP) 1 and 2 were present in the CM. However, suppression of invadopodia formation was found that was specific to TIMP2 activity. Conclusions Our findings indicate that TIMP2 levels in the tumour microenvironment may have prognostic value in patients with PDAC. Furthermore, activation of TIMP2 expressing monocytes in the primary tumour could present a potential therapeutic opportunity to suppress cell invasion in PDAC.

Abstract
Purpose: To compare the efficacy and safety of right internal jugular vein (IJV) approach and right innominate vein (INV) approach for US-guided totally implantable venous access devices (TIVADs), and to explore the advantages and disadvantages of the two approaches. Methods: Six hundred and nineteen adult patients had long-term infusion and chemotherapy needs and inconvenience of peripheral venous infusion. Right INV approach was used to implant 339 cases of TIVADs, and right IJV approach was used to implant 280 cases of TIVADs. The success rate of one-time catheterization and the incidence of complications in the two groups were retrospectively analyzed. Results: All patients were successfully implanted in TIVAD. The success rates of one-time puncture in INV group and IJV approach group were 98.53% (334/339) and 95.36% (267/280), respectively. There was significant difference between the two groups (P=0.020). The incidence of perioperative complications was 1.18% (4/339) and the long-term complications was 3.54% (12/339) in the right INV group. The incidence of perioperative complications was 1.43% (4/280) and the long-term complications was 3.93% (11/280) in the right INV group. There was no significant difference in the incidence of complications between the two groups (P=0.785，P=0.799, respectively). Conclusions: US-guided TIVADs via the right INV approach and the right IJV approach are both safe and reliable. The right INV approach improves the one-time puncture success rate, as long as the technique is properly operated, serious complications rarely occur.
