Renal cell carcinoma (RCC) is associated with a variety of different histopathologic subtypes in which each subtype may be further subclassified. These entities carry with them unique prognoses and necessitate treatment with specific immunotherapy agents should advanced disease be uncovered. Meanwhile, aberrant physiologic processes may lead to unique histologic findings within these subtypes, further complicating management and prognostication. Heterotopic ossification within RCC is one of these rare occurrences and was once thought to have favorable prognostic implications. We report a case of a young female with papillary type 2 RCC with heterotopic ossification.

Incident reporting and management systems are used to gather and process information about day-today occurring incidents such as road accidents, domestic violence, burglaries , harassment, etc. Nowadays, citizens can report such incidents through different means such as calling national emergency lines via telephones or mobile phones, or sending reports via Internet through web-browsers, or smartphones-based applications. A quick and appropriate response to the incidents can reduce both societal costs and fatality rates. Many smartphone-based applications and web-platforms exist that allow a person to send an image, a video, or map-based incident related reports to alert the concerned authority. A few reporting platforms and systems are also available to report the incidents anonymously to the relevant authorities to protect the eyewitnesses or victims. Our main contribution is the literature review of the incident reporting and management systems (based on smartphones and web-based) in terms of functionality, implementation details, technology, performance, security, and anonymity.

Histiocytic sarcoma (HS) rarely involves extranodal sites, such as the spleen. We report a unique pediatric case of massive splenomegaly and refractory Coombs negative hemolytic anemia (CNHA) secondary to HS. The CNHA resolved completely after an emergent splenectomy. Next generation sequencing (NGS) revealed novel ASXL1, PTPN11, KIT, and TP53 mutations, unmasking a clonal heterogeneity within the same neoplasm.

The use of peer-to-peer (P2P) networks for multimedia distribution has spread out globally in recent years. This mass popularity is primarily driven by the efficient distribution of content, also giving rise to piracy and copyright infringement as well as privacy concerns. An end user (buyer) of a P2P content distribution system does not want to reveal his/her identity during a transaction with a content owner (merchant), whereas the merchant does not want the buyer to further redistribute the content illegally. Therefore, there is a strong need for content distribution mechanisms over P2P networks that do not pose security and privacy threats to copyright holders and end users, respectively. However, the current systems being developed to provide copyright and privacy protection to merchants and end users employ cryptographic mechanisms, which incur high computational and communication costs, making these systems impractical for the distribution of big files, such as music albums or movies., El uso de soluciones de igual a igual (peer-to-peer, P2P) para la distribución multimedia se ha extendido mundialmente en los últimos años. La amplia popularidad de este paradigma se debe, principalmente, a la distribución eficiente de los contenidos, pero también da lugar a la piratería, a la violación del copyright y a problemas de privacidad. Un usuario final (comprador) de un sistema de distribución de contenidos P2P no quiere revelar su identidad durante una transacción con un propietario de contenidos (comerciante), mientras que el comerciante no quiere que el comprador pueda redistribuir ilegalmente el contenido más adelante. Por lo tanto, existe una fuerte necesidad de mecanismos de distribución de contenidos por medio de redes P2P que no supongan un riesgo de seguridad y privacidad a los titulares de derechos y los usuarios finales, respectivamente. Sin embargo, los sistemas actuales que se desarrollan con el propósito de proteger el copyright y la privacidad de los comerciantes y los usuarios finales emplean mecanismos de cifrado que implican unas cargas computacionales y de comunicaciones muy elevadas que convierten a estos sistemas en poco prácticos para distribuir archivos de gran tamaño, tales como álbumes de música o películas., L'ús de solucions d'igual a igual (peer-to-peer, P2P) per a la distribució multimèdia s'ha estès mundialment els darrers anys. L'àmplia popularitat d'aquest paradigma es deu, principalment, a la distribució eficient dels continguts, però també dóna lloc a la pirateria, a la violació del copyright i a problemes de privadesa. Un usuari final (comprador) d'un sistema de distribució de continguts P2P no vol revelar la seva identitat durant una transacció amb un propietari de continguts (comerciant), mentre que el comerciant no vol que el comprador pugui redistribuir il·legalment el contingut més endavant. Per tant, hi ha una gran necessitat de mecanismes de distribució de continguts per mitjà de xarxes P2P que no comportin un risc de seguretat i privadesa als titulars de drets i els usuaris finals, respectivament. Tanmateix, els sistemes actuals que es desenvolupen amb el propòsit de protegir el copyright i la privadesa dels comerciants i els usuaris finals fan servir mecanismes d'encriptació que impliquen unes càrregues computacionals i de comunicacions molt elevades que fan aquests sistemes poc pràctics per a distribuir arxius de grans dimensions, com ara àlbums de música o pel·lícules.

Peer-reviewed Recent decades have witnessed a swift development in network structures like Peer-to-Peer (P2P) systems, offering advantages such as significantly reducing the setup running cost for the content providers and providing end users data access within very short time. However, today¿s P2P distribution systems are severely abused by illegal re-distributions. The enforcement of copyright protection mechanisms in these systems poses serious privacy threats to end users. Various researchers have examined the challenges characterizing these systems from diverse viewpoints, proposing strategic solutions. This paper, to the best of our knowledge, for the first time conducts a review analysis focused on security, privacy and anonymity in P2P systems, describing the challenges and solutions that are associated with legal content distribution in them.

Jotun Kemisk Fabrik A/S was founded in March 1926, operating only in Norway until 1962 when it began to expand internationally. Today Jotun operates in more than 70 countries, and is one of the world’s leading manufacturers of paints and coatings. Jotun has been in the Chinese market since 1983, initially focusing only on marine coatings and protective coatings where the brand became very successful. Encouraged by this, Jotun China decided to enter the Chinese decorative paint market in 2001 with the long term goal of becoming the market’s leading brand. However, after 8 years in the Chinese decorative paint market, Jotun China has not been able to replicate its previous successes. Therefore, we the authors of this thesis, working in collaboration with Jotun China staff, set out first to determine the viability of Jotun’s latest strategy for the Chinese decorative paint market, and second to suggest concrete steps to follow if and when executing this strategy. Our findings are based on extensive market research, as well as collection and analysis of both primary and secondary data. Our thesis is presented in six parts. In Part One, we provide an introduction to our thesis and background information of Jotun, define our problem statement, research aim, and research questions, and describe the types of difficulties we encountered. In Part Two, we give an overview of our research and data collection methodology. We describe how data was collected and analysed, and comment on its reliability and validity. In Part Three, we provide short summaries of the various theories used in our analysis of Jotun and its strategy for the decorative paint market in China. In Part Four, we detail our secondary findings, followed by our primary findings. The secondary findings consist of an overview of China’s decorative paint industry and real estate market, as well as the meaning and importance of Guanxi in China. The primary findings consist of summaries and analysis of interviews we conducted with Jotun China employees, key dealers and their employees, and other relevant industry experts. In Part Five, we present our internal, external, and SWOT analyses of Jotun China. In Part Six, we conclude by presenting our recommendations with regards to achieving Jotun China’s goals in the Chinese decorative paint market. We explain why Jotun should continue operating in this market, and provide specific steps to properly execute the company’s latest strategy.
