An Egocentric Look at Video Photographer Identity  [PDF]
Yedid Hoshen,Shmuel Peleg
Computer Science , 2014,
Abstract: Egocentric cameras are being worn by an increasing number of users, among them many security forces worldwide. GoPro cameras already penetrated the mass market, reporting substantial increase in sales every year. As head-worn cameras do not capture the photographer, it may seem that the anonymity of the photographer is preserved even when the video is publicly distributed. We show that camera motion, as can be computed from the egocentric video, provides unique identity information. The photographer can be reliably recognized from a few seconds of video captured when walking. The proposed method achieves more than 90% recognition accuracy in cases where the random success rate is only 3%. Applications can include theft prevention by locking the camera when not worn by its rightful owner. Searching video sharing services (e.g. YouTube) for egocentric videos shot by a specific photographer may also become possible. An important message in this paper is that photographers should be aware that sharing egocentric video will compromise their anonymity, even when their face is not visible.
"Bone scan in Erdheime Chester disease "
"Eftekhari M,Darakhshan S,Vakili A,Fard Esfahani A
Iranian Journal of Nuclear Medicine , 1999,
Abstract: In spite of very high sensitivity, bone scan is quite nonspecific in evaluation of bony lesions. In interpretation of bone scan special attention to patient’s clinical presentation and correlation with other lab and imaging modalities should be paid. In this report a patient with Erdheim Chester disease a rare and unusual form of lipidosis is presented and the pattern of 99mTc-MDP bone scan and other imaging modalities are discussed.
Erdheim-Chester Disease with Right Atrial Tumor and “Temporal Arteritis”  [PDF]
Joseph Skalski, William D. Edwards, Eric L. Matteson
Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2012, DOI: 10.4236/ojra.2012.23008
Abstract: Erdheim-Chester disease is an unusual syndrome characterized by non-Langerhans cell histiocytosis which can mimic rheumatologic diseases. We report a case of Erdheim-Chester masquerading as giant cell arteritis, which was success-fully managed with anakinra as anti IL-1 therapy.
Public use of the Internet at Chester library, UK.
Katherine Turner,Margaret Kendall
Information Research: an international electronic journal , 2000,
Abstract: Substantial investment is accelerating the provision of public access to the Internet in UK public libraries. Monitoring and evaluation will be essential to inform policies, developments and justify the new services. This paper reports on quantitative and qualitative research into the use being made of the Internet facilities at Chester Library between August 1998 and May 1999. A questionnaire survey of 178 users revealed substantial use by non-library members, mostly aged between 16 and 35, with only slightly higher use by men than by women. Most of the sample had received no formal training in Internet use and the most popular application was e-mail. Follow-up interviews with 9 users provide examples of the value of the service to users and recommendations for increased training and support from librarians. Analysis of the results includes recommendations for Chester libraries and contributes to the wider debate on the changing roles of public libraries. Further research on the monitoring and evaluation of IT-based services in public libraries is now underway at Manchester Metropolitan University, with Cheshire libraries being one of three library authority project partners in VITAL, an 18 month study funded by the Library and Information Commission.

Archivos de la Sociedad Espa?ola de Oftalmología , 2004, DOI: 10.4321/S0365-66912004001000009
Abstract: case report: a patient was studied because of upper lid bilateral edema and xanthelasmae-like lesions after three years of evolution. during the ophthalmologic examination orange-yellowish lesions and two symmetrical tumours were observed on the temporal part of both upper lids. corticoid-therapy was undertaken which reduced the size of the tumours, however the size increased again after the discontinuation of treatment. a biopsy was performed and lid xanthogranulomatosis was diagnosed. other systemic examinations were normal. discussion: erdheim-chester disease is a xanthogranulomatosis that can affect ocular and periorbital structures. combination of xanthelasmae-like lesions and bilateral orbital masses should make us consider this process and try to locate any associated systemic conditions.

Abstract: This case report describes the case of a 69-year-old man who presented otherwise well to the gastroenterology department with unspecific abdominal symptoms, nausea, vomiting and weight loss. ECD involving the gastrointestinal tract was confirmed clinically, radiologically and histologically.Gastroenterological manifestation of ECD is rare but should be considered in the differential diagnosis in patients presenting with evidence of multi-organ disease and typical radiological features of Erdheim-Chester disease elsewhere.Erdheim-Chester Disease (ECD) is a rare multisystem histiocytosis characterized by the xanthomatous or xanthogranulomatous infiltration of tissues with histiocytes, surrounded by fibrosis. The disease can affect multiple organs systems, but gastrointestinal involvement, is exceedingly rare. We describe here the case of a 69-year old man with ECD who presented to the gastroenterology department with unspecific abdominal symptoms, nausea, vomiting and weight loss.A previously fit and well 69-year-old man was admitted to the gastroenterology department with a short one month history of lethargy, decreased appetite, persistent vomiting, significant weight loss of six kilograms over 1 month and a dry cough. He denied abdominal pain, haematemesis, dysphagia and a change in bowel habit and described no cardiac, respiratory, neurological symptoms or bone pain. His past medical history includes appendectomy and total hip joint replacement. At the time of admission, he was not on any regular medication.Physical examination revealed that he was febrile (38.8C°) and appeared cachexic but with no peripheral stigmata of chronic liver disease. His abdominal examination revealed hepatomegaly but no other organomegaly, per rectal examination was unremarkable. His cardiopulmonary examinations were unremarkable apart from bilateral pitting edema up to his ankles. Peripheral blood analysis revealed an anaemia of chronic disease with hemoglobin of 108 g/L (norm - male 1

History Studies : International Journal of History , 2010,
Abstract: Having been in a search of stocks and markets due to the industrial revolution, the imperialist states have made a bid for obtaining a concession of railway from the Ottoman Empire since the mids of the nineteenth century. As soon as these states have struggled for obtaining the railway concession by a great deal of different requirements, they have tried to enlarge their domains that would contain abundant oil fields on the Ottoman mainland. At the beginning of the twentieth century, America got involved in these states with the project “Chester”. n this study, the attempts of the Chester Group on the obtainment of the railway concession and the results have been evaluated in collaboration with the news and reports about the subject in the newspaper named “Hakimiyet-i Milliye”.
Who clicks there!: Anonymizing the photographer in a camera saturated society  [PDF]
Peter Schaffer,Djamila Aouada,Shishir Nagaraja
Computer Science , 2011,
Abstract: In recent years, social media has played an increasingly important role in reporting world events. The publication of crowd-sourced photographs and videos in near real-time is one of the reasons behind the high impact. However, the use of a camera can draw the photographer into a situation of conflict. Examples include the use of cameras by regulators collecting evidence of Mafia operations; citizens collecting evidence of corruption at a public service outlet; and political dissidents protesting at public rallies. In all these cases, the published images contain fairly unambiguous clues about the location of the photographer (scene viewpoint information). In the presence of adversary operated cameras, it can be easy to identify the photographer by also combining leaked information from the photographs themselves. We call this the camera location detection attack. We propose and review defense techniques against such attacks. Defenses such as image obfuscation techniques do not protect camera-location information; current anonymous publication technologies do not help either. However, the use of view synthesis algorithms could be a promising step in the direction of providing probabilistic privacy guarantees.

Abstract: Caso clínico: Paciente con edema bilateral de párpados superiores y lesiones similares a xantelasmas de tres a os de evolución. La exploración oftalmológica mostraba dos tumoraciones temporales simétricas en ambos párpados superiores con lesiones naranjo-amarillentas. Se pautaron corticoides que hicieron disminuir el tama o de las tumoraciones, con recidiva de los mismos al suspender dicha medicación. La biopsia reveló una xantogranulomatosis palpebral. El resto de las exploraciones sistémicas fueron normales. Discusión: La enfermedad de Erdheim-Chester es una xantogranulomatosis que puede afectar a las estructuras oculares y periorbitarias. La combinación de lesiones similares a xantelasmas y masas orbitarias bilaterales deben hacernos pensar en este proceso y buscar la posible afectación sistémica. Case report: A patient was studied because of upper lid bilateral edema and xanthelasmae-like lesions after three years of evolution. During the ophthalmologic examination orange-yellowish lesions and two symmetrical tumours were observed on the temporal part of both upper lids. Corticoid-therapy was undertaken which reduced the size of the tumours, however the size increased again after the discontinuation of treatment. A biopsy was performed and lid xanthogranulomatosis was diagnosed. Other systemic examinations were normal. Discussion: Erdheim-Chester disease is a xanthogranulomatosis that can affect ocular and periorbital structures. Combination of xanthelasmae-like lesions and bilateral orbital masses should make us consider this process and try to locate any associated systemic conditions.
