A Forensic Email Analysis Tool Using Dynamic Visualization

Communication between people counts to the most important information of today’s business. As a result, in case of forensic investigations in big companies, analysis of communication data in general and especially email, as the still most widely used business communication platform with an immense and still growing volume, is a typical task in digital forensics. One of the challenges is to identify the relevant communication partners and structures in the suspects surrounding as quickly as possible in order to react appropriately and identify further targets of evaluation. Due to the amount of emails in typical inboxes, reading through all the mails renders impractical. Therefor, forensic investigators need tools that support them in quickly receiving an impression of a suspect’s email communication, identifying the relevant communication partners, and realizing communication patterns in single or even multiple email accounts. We introduce an open source forensic email analysis tool that provides exactly by means of a responsive and interactive graph visualization of email data supported by statistical information

Il giallo italiano a quattro mani

Die vorliegende Diplomarbeit hat sich zum Ziel gesetzt, den Entstehungsprozess von Kriminalromanen, welche von zwei Co-Autoren verfasst wurden, darzustellen. Dabei sollen sowohl die individuellen Prozesse veranschaulicht werden als auch jene Schritte, die die beiden Schriftsteller gemeinsam bewältigen müssen (wie zum Beispiel Diskussionen über den tatsächlichen Handlungsverlauf, Aufteilung der Kapitel etc.). Im Zentrum der sprachwissenschaftlichen Instrumente, die dazu benötigt werden, steht das prozedurale Textmodell von Robert-Alain de Beaugrande und Wolfgang Dressler; dieses Modell versteht jedwede Art von Text (nicht nur den schriftlich, sondern auch den mündlich produzierten) als ein im mentalen Prozess entstandenes Produkt. Beaugrande und Dressler definieren fünf Stadien, in denen jeweils ein besonderer Aspekt im Vordergrund steht: die Planung, Ideation, Ausdruck, Entwicklung und grammatikalische Synthese . Sind nun zwei Schriftsteller an der Entstehung eines Romanes beteiligt, gilt es, auch die organisatorischen Arbeiten, die nur in Form von Diskussionen abgewickelt werden können, zu berücksichtigen. Diese organisatorischen Aufgaben führen dazu, dass die kommunikative Ebene sich im Entstehungsprozess des Romans erweitert. Wenn laut Jakobson’sches Kommunikationsmodell Sender, Botschaft und Empfänger an jeder Form von Kommunikation teilhaben, so sind in Hinblick auf Literatur diese drei Komponenten gleichzusetzen mit dem Schriftsteller, Roman und Rezipient. Das prozedurale Textmodell von Beaugrande und Dressler bezieht auch den Rezipienten mit ein und erschafft somit ein Textmodell, welches sowohl die mentalen Prozesse des Textproduzenten als auch jene des Textrezipienten miteinschließt. Für die vorliegende Diplomarbeit liegt der Schwerpunkt jedoch auf der Beziehung zwischen dem Textproduzenten und dem Text selbst. Diese verkompliziert sich beim Auftreten eines zweiten Schriftstellers, der am selben Text mitarbeitet. Somit entsteht eine neue komunikative Ebene, die sich allerdings auf die Verständigung zwischen den Autoren und deren Auswirkung auf die Textentstehung und dem schließlich vorliegenden Roman konzentriert. Zur Untersuchung dieses intensiven Prozesses der Verfassung eines literarischen Werkes, wurden die Kriminalromane "Quattro gocce d’acqua piovana" von Piero Colaprico und Pietro Valpreda und "Macaronì. Romanzo di santi e delinquenti" von Francesco Guccini und Loriano Macchiavelli ausgewählt. Die Autoren Colaprico, Guccini und Macchiavelli wurden zur Thematik des „vierhändigen Schreibens“ interviewt, um Bestätigungen über die theoretischen Modelle einzuholen. Die Zusammenfassungen der Interviews sowie die Präsentation der wichtigsten Kriminalromane, die von diesen Schriftstellerpaaren verfasst wurden, bilden daher einen wichtigen Anhaltspunkt im Gesamtzusammenhang der vorliegenden Diplomarbeit. Des Weiteren beschäftigt sich ein Kapitel mit Stilanalysen der Kriminalromane, wobei jeweils andere Werke derselben Autoren die Basis zum Vergleichen und Feststellen von tatsächlich individuellen Stilzügen dienen: somit bildet die zusätzliche Analyse von La quinta stagione die Grundvoraussetzung, um individuelle Stilmerkmale Piero Colapricos zu definieren; dieselben Aufgaben erfüllen die Romane "Cròniche epafániche" von Francesco Guccini und "Ombre sotto i portici" von Loriano Macchiavelli. Die Stilanalysen stellen den literaturwissenschaftlichen Zugang zur Thematik des Schreibprozesses zu vier Händen dar, denn auch die Textoberfläche, wie sie dem Leser präsentiert wird, beinhaltet bei einer detaillierten Untersuchung aussagekräftige Hinweise über die Arbeitsweisen der Schriftsteller, die auch anhand des Sprachstils (zu dem auch die Auswahl der Stilmittel gehört) wie auch der allgemeinen Textstruktur ersichtlich werden. Die vorliegende Arbeit eint somit sprach- und literaturwissenschaftliche Zugänge zur Thematik des italienischen Kriminalromans zu vier Händen. Der Epilog der vorliegenden Diplomarbeit zieht Bilanz aus den bis dahin aufgestellten Hypothesen und versucht, diese in Grafiken darzustellen. Das prozedurale Textmodell über die Entstehung von Texten von Beaugrande und Dressler, das Kommunikationsmodell von Jakobson sowie die Erkenntnisse aus den Stilanalysen bilden dabei die wissenschaftlichen Grundpfeiler

Guided biopsy of osseous pathologies in the jaw bone using a 3D-printed, tooth-supported drilling template

Suspicious radiological findings in the jaw bone require histopathological examination for the confirmation of a diagnosis. As pathologies in this region are difficult to reach or are in close proximity to relevant anatomical structures, e.g. tooth roots or nerves, they often represent a challenge. Such factors may adversely affect the predictability of the surgical outcome of a biopsy of the osseous tissues. This technical note introduces a novel method for performing a digitally planned, guided biopsy. For this purpose, a cone beam computed tomography scan and an intraoral scan are superimposed using specific planning software. The resulting three-dimensionally printed, tooth-supported drilling template is designed for a trephine biopsy. It allows a precise, minimally invasive approach, with an exact three-dimensional determination of the biopsy location prior to surgery. The risk of devitalization of the neighbouring teeth or possible damage to the nerve structures can be minimized. Furthermore, a small access flap can be sufficient. In summary, the method of bone biopsy presented here allows high precision and greater predictability for biopsy sampling and is minimally invasive for the patient

In vitro kinetic study of growth and mineralization of osteoblast-like cells (Saos-2) on titanium surface coated with a RGD functionalized bisphosphonate

Osteoconduction and osseointegration are the critical stages for implantation success. Peptides containing RGD (Arg-Gly-Asp) adhesive sequence are known to promote cell adhesion and consequently to favor osseointegration of medical devices. In this study, RGD peptides were coupled to a bisphosphonate used as an anchor system and chemically adsorbed on polished titanium discs. Two different concentrations, 10−10 mol/L (RGD 10−10) and 10−4 mol/L (RGD 10−4) were compared to non coated discs (RGD 0). Adhesion, spreading, and mineralization of osteoblast-like cells (Saos-2) were assessed. Mineralization kinetic was done at 3, 6, 10, 14, and 18 days of culture; the extent of mineral deposits was quantified by image analysis. Histogram repartitions of nuclear area, characterizing cell spreading, showed a shift to higher values in cells cultured on RGD coated titanium disks. Mineralization started at day 3 in the three groups, but had a faster development in the RGD 10−10 group from day 6 to day 18 compared to RGD 0 and RGD 10−4. At day 18, the percentage of mineralized area was significantly higher for RGD 10−10 compared to RGD 0 (p < 0.05). In the present study, this new method was found suitable to anchor RGD containing species on titanium: this favored adhesion and spreading of osteoblast-like cells and mineralization compared to noncoated titanium

Advanced Imaging and Preoperative MR-Based Cinematic Rendering Reconstructions for Neoplasms in the Oral and Maxillofacial Region

This case study highlights the use of cinematic rendering (CR) in preoperative planning for the excision of a cyst in the oral and maxillofacial region of a 60-year-old man. The patient presented with a firm, non-tender mass in the right cheek, clinically suspected to be an epidermoid cyst. Conventional imaging, including dental magnetic resonance imaging (MRI) protocols, confirmed the lesion's size, location, and benign nature. CR reconstructions, combining advanced algorithms and novel skin presets, allow for the generation of highly realistic, three-dimensional visualizations from conventional imaging datasets. CR provided an enhanced, detailed depiction of the lesion within its anatomical context, significantly improving spatial understanding for surgical planning. The surgical excision was performed without complications, and histological analysis confirmed the diagnosis of a benign epidermoid cyst with no evidence of dysplasia or malignancy. This case demonstrates the potential of CR to refine preoperative planning, especially in complex anatomical regions such as the face and jaw, by offering superior visualization of superficial and deep structures. Thus, the integration of CR into clinical workflows has the potential to lead to improved diagnostic accuracy and better surgical outcomes

Technology enhanced learning:a role for video animation

The last 20 years has seen a shift in medical education from printed analogue formats of knowledge transfer to digital knowledge transfer via media platforms and virtual learning environments. Traditional university medical teaching was characterised by lectures and printed textbooks, which to a degree still have an important role to play in knowledge acquisition, but which in isolation do not engage the modern learner, who has become reliant on digital platforms and 'soundbite' learning. Recently, however, traditional methods of teaching and learning have been augmented by, and indeed sometimes replaced by, the alternative learning methods such as: problem-based learning; a greater integration of basic science and clinical considerations; smaller teaching groups; the 'flipped classroom' concept; and various technological tools which promote an interactive learning style. The aim of these new teaching methods is to overcome the well-documented limitations of traditional lectures and printed material in the transfer of knowledge from expert to student, by better engaging the minds of more visual learners and encouraging the use of diverse resources for lifelong learning. In this commentary paper, we share the concept of video animation as an additional educational tool, and one that can help to integrate molecular, cellular and clinical processes that underpin our understanding of biology and pathology in modern education. Importantly, while they can provide focused and attractive formats for 'soundbite' learning, their aim as a tool within the broader educational toolbox is to direct the interested reader towards more traditional formats of learning, which permit a deeper dive into a particular field or concept. In this manner, carefully constructed video animations can serve to provide a broad overview of a particular field or concept and to facilitate deeper learning when desired by the student

Marx & Moderne: Dialektik der Befreiung oder Paradoxien der Individualisierung?

This article discusses the use of “paradox” and “ambivalence” as key terms of social theory as suggested by modernization theories instead of the dialectical term “contradiction”. It is shown that the underlying assumption of these concepts – the “paradoxical force to freedom” – is based on questionable and not thought-out premises. In contrast, the use of Hegel’s dialectical idea of freedom and Marx’s Theory of Productive Forces offers a perspective in which “paradoxes” stated by the modernization theories can be conceptualised and in which the underlying changes can be identified as a momentum of a Dialectic of Liberation. The historical basis of the “Paradoxes of Individualization” are changes in the relation of autonomy and heteronomy related to the radical change in the organisation of work

Accuracy of guided biopsy of the jawbone in a clinical setting: A retrospective analysis

The aim of this study was to investigate the accuracy of a previously described technique for guided biopsy of osseous pathologies of the jawbone in a clinical setting. The data sets of patients who had undergone guided biopsy procedures were retrospectively examined for accuracy. Digital planning of the biopsies and manufacturing of the tooth-supported drilling template were performed with superimposed cone beam computed tomography and intraoral scans using implant planning software. After a trephine biopsy was taken using the template, the postoperative low-dose cone beam computed tomography was analyzed for accuracy using the planning software with the corresponding (digitally-planned) biopsy cylinder. The mean angular deviation was 4.35 ± 2.5°. The mean depth deviation was -1.40 ± 1.41 mm. Guided biopsy seems to be an alternative to a conventional approach for minimally invasive and highly accurate jawbone biopsy
