The Serum Paraprotein Level Related to the Number of Plasmacytoma-5563 Cells in C3H Mice

An ascitic form of plasmacytoma (MP-5563) in C3H mice has proved stable on transplantation. A simple linear relationship was demonstrated between the serum level of the paraprotein produced and the total number of plasmacytoma cells within the ascitic fluid

Market-Based Approach to Mobile Surveillance Systems

The active surveillance of public and private sites is increasingly becoming a very important and critical issue. It is, therefore, imperative to develop mobile surveillance systems to protect these sites. Modern surveillance systems encompass spatially distributed mobile and static sensors in order to provide effective monitoring of persistent and transient objects and events in a given area of interest (AOI). The realization of the potential of mobile surveillance requires the solution of different challenging problems such as task allocation, mobile sensor deployment, multisensor management, cooperative object detection and tracking, decentralized data fusion, and interoperability and accessibility of system nodes. This paper proposes a market-based approach that can be used to handle different problems of mobile surveillance systems. Task allocation and cooperative target tracking are studied using the proposed approach as two challenging problems of mobile surveillance systems. These challenges are addressed individually and collectively

Mechanisms and treatment of femoropoplitealin-stent restenosis

The problem of stent restenosis (SRI) in the femoropopliteal artery (FP) has not yet been resolved; the predictive factors of the mechanisms and treatment in FP-ISR are unclear. The objective of this study is to investigate and give a clear explanation of the mechanisms and factors of FP-ISR that contributed to ISR, as well as a brief survey of the methods that have been used to treat FP-ISR. Methods of treatment with FP-ISR, such as medical, endovascular and bypass surgery, are used for several types of FP-ISR, the DEB device chosen as the first recommended method due to its effectiveness and ease of use

Generalized Grassmannian Coherent States For Pseudo-Hermitian nn Level Systems

The purpose of this paper is to generalize fermionic coherent states for two-level systems described by pseudo-Hermitian Hamiltonian \cite{Trifonov}, to n-level systems. Central to this task is the expression of the coherent states in terms of generalized Grassmann variables. These kind of Grassmann coherent states satisfy bi-overcompleteness condition instead of over-completeness one, as it is reasonably expected because of the biorthonormality of the system. Choosing an appropriate Grassmann weight function resolution of identity is examined. Moreover Grassmannian coherent and squeezed states of deformed group $SU_{q}(2)$ for three level pseudo-Hermitian system are presented.Comment: 17 page

A hybrid haptic stimulation wearable device to recover the missing sensation of the upper extremity prostheses’ users

A hybrid haptic feedback stimulation system that is capable in sensing the surface texture, and the temperature, simultaneously, was designed for a prosthetic hand to provide a tactile sensation to amputation patients. In addition, the haptic system was developed to enable the prosthetic’s users to implement withdrawal reflexes due to the thermal noxious stimulus in a quick manner. The re-sensation is achieved by non-invasively stimulating the skin of the patients’ residual limbs, based on the type and the level of tactile signals provided by the sensory system of the prostheses. Accordingly, a novel hybrid pressure-vibration- temperature feedback stimulation system was design to provide a huge information regarding the prostheses environment to the users without brain confusing or requiring long pre-training. An evaluation of sensation and response will be performed with healthy volunteers to evaluate the ability of the haptic system to stimulate the human nervous system. The results were presented in term of Stimulus Identification Rate (SIR). The test results and the volunteers' response established evidence that amputees are able to recover their sense of the contact pressure, the surface texture, and the object temperature as well as to perform thermal withdrawal reflexes using the solution developed in this work

A Hybrid Haptic Feedback Stimulation Prosthetic Device to Recover the Missing Sensation of Upper Extremity Amputees

Anon-invasive hybrid haptic feedback stimulation system that can sense the contact pressure was designed for a prosthetic hand, in order to recover the missing sensation of the amputation patients. The main objective of this work is to develop and evaluate the first step of a novel approach for a lightweight, 7 Degrees-Of-Freedom (DOF) prosthetic arm to perform an effective object manipulation and grasping. Furthermore, to convey the tactile information about the contact pressure with high identification accuracy. However, a novel wearable hybrid pressure-vibration haptic feedback stimulation device for providing the tactile information about the contact pressure between the prosthetic hand and the grasped objects to the user’s brain is designed to achieve the main objective of this study. An evaluation of sensation and response has been conducted with forty healthy subjects to evaluate the ability of the haptic system to stimulate the human nervous system. The results in term of Stimulus Identification Rate (SIR) presented that the whole participants were correctly able to discriminate the sensation of touch, stare of touch, end of touch, and grasping objects. While 94%, and 96% of the entire stimuli were successfully identified by the volunteers during the experiments of slippage, pressure level, respectively

Focus Raqqa: inventory of Museum collections and reconstruction of missing tablets

The National Museum of Raqqa in Syria has suffered immensely from the ongoing violence since 2011. Much of its valuable collection of movable archaeological heritage (ca. 6000 items) is considered lost. Starting from 500 of the most precious objects of the museum stored in the Raqqa Central Bank and stolen from there in 2013, the pilot project Focus Raqqa created a concrete, workable database to enable identification by Syrian and international police and heritage institutions. The project made a pivotal first step towards potential reconstruction of the Raqqa Museum in the future. The Raqqa museum collection included cuneiform tablets. Some of the tablets were cast before the war to allow detailed study in Europe. Today the tablets have vanished. The pilot project Scanning for Syria safeguarded information from the lost artefacts by making high-resolution three-dimensional scans of the silicone rubber moulds and subsequently physical replicas of the original objects by 3D printing. The short life expectancy (30 years) of the moulds necessitated measures for long-term preservation. The Scanning for Syria team not only succeeded at the preservation and sharing of knowledge in the academic circle. It also told the story of Syrian culture and its people to everyone for raising more voices in the united effort to keep cultural heritage safe in a zone of conflict. Digital Archaeolog

Une cause rare d’exophtalmie

Une enfant de 3 ans, issue d’un mariage non consanguin, deuxième d’une fratrie de 3, et sans antécédents pathologiques particuliers. Le début de la symptomatologie remonte à un mois par la constatation par la maman d’une exophtalmie de l’œil gauche qui augmentait rapidement de volume sans autres signes associés. A l’examen clinique, on notait la présence d’une importante exophtalmie de l’œil gauche avec bombement du cavum sans déficits neurologiques, le fond d’œil a objectivé une atrophie optique temporale. Une tomodensitométrie orbitaire a objectivé un processus énorme intra-orbitaire iso dense infiltrant la base du crâne, le sinus caverneux, le sinus sphénoïdal gauche  avec extension vers le cavum sur une étendue de 40 mm
