Mitral valve diseases

The heart is a pump consisting of 4 chambers:2 atria and 2 ventricles and 4 valves one of them is mitral valve which is located betweenthe left atrium and the left ventricle and prevents the backward flow of blood.Ithas several unique features: Mitral annulus, two leaflets, the chordae tendineaeand papillary muscles. The mitral valve may become stenotic or may regurgitate. Regurgitation(or leakage of the valve): When the valve (s) do not close completely. Stenosis (or narrowing of the valve): When the valve (s) opening becomes narrowed. Mitral stenosis is categorized as mild, moderate or severe it is typically causedby (Rheumatic fever, A congenital heart, Calcium deposits .....) and it caused severalsymptoms such as: dyspnea, hemoptysis, fatigue, Chest pain and others Where as the Signs and symptoms of mitral valve regurgitation, can include: Abnormal heart sound, Shortness of breath, Heart palpitations, Fatigue, edma, Coughing.

Mission AI: the new system technology

Offers a strategic perspective on AI and the process of embedding it in society. After decades of research, Artificial Intelligence (AI) is now entering society at large. Due to its general purpose character, AI will change society in multiple, fundamental and unpredictable ways. Therefore, the Netherlands Scientific Council for Government Policy (WRR) characterizes AI as a system technology: a rare type of technologies that have a systemic impact on society. Earlier system technologies include electricity, the combustion engine and the computer. The history of these technologies provides us with useful insights about what it takes to direct the introduction of AI in society.

Mirror Geometry of Lie Algebras, Lie Groups and Homogeneous Spaces

As K. Nomizu has justly noted [K. Nomizu, 56], Differential Geometry ever will be initiating newer and newer aspects of the theory of Lie groups. This monograph is devoted to just some such aspects of Lie groups and Lie algebras. New differential geometric problems came into being in connection with so called subsymmetric spaces, subsymmetries, and mirrors introduced in our works dating back to 1957 [L.V. Sabinin, 58a,59a,59b]. In addition, the exploration of mirrors and systems of mirrors is of interest in the case of symmetric spaces. Geometrically, the most rich in content there appeared to be the homogeneous Riemannian spaces with systems of mirrors generated by commuting subsymmetries, in particular, so called tri-symmetric spaces introduced in [L.V. Sabinin, 61b]. As to the concrete geometric problem which needs be solved and which is solved in this monograph, we indicate, for example, the problem of the classification of all tri-symmetric spaces with simple compact groups of motions. Passing from groups and subgroups connected with mirrors and subsymmetries to the corresponding Lie algebras and subalgebras leads to an important new concept of the involutive sum of Lie algebras [L.V. Sabinin, 65]. This concept is directly concerned with unitary symmetry of elementary par- cles (see [L.V. Sabinin, 95,85] and Appendix 1). The first examples of involutive (even iso-involutive) sums appeared in the - ploration of homogeneous Riemannian spaces with and axial symmetry. The consideration of spaces with mirrors [L.V. Sabinin, 59b] again led to iso-involutive sums.

Mind conversation = التنبؤ بالحروف العربية من خلال الإشارات الدماغية

Throughout history, humans have long dreamed of understanding what goes on inside the human mind—what people are thinking or feeling. It seemed like something from a far-off future or a magical realm. But now, thanks to amazing technology called EEG and BCI, this dream is turning into reality. EEG stands for electroencephalography. It's a way of listening to what the brain is up to by placing small sensors on or near the head. These sensors pick up tiny electrical signals produced by the brain's activity. It's like eavesdropping on the brain's conversations with itself. BCI, or Brain-Computer Interface, is like a bridge between the brain and machines. It lets the brain talk to devices or computers. This means people can control things without using their hands or voices. Our system takes advantage of EEG and BCI to create something helpful, a special mobile app. This app is designed for people who can't move their bodies, like those who are paralyzed. It helps them use their phones to express what they are thinking about.

Mild Stress and Healthy Aging : Applying hormesis in aging research and interventions

Stress is a double edged sword. Whereas chronic stress has well known harmful effects, recent research shows that intermittent exposure of cells and organisms to mild stress can improve various biological parameters, including severe stress tolerance, health span and longevity. Mild stress-induced hormesis is potentially a powerful tool in gerontological research and interventions. This book brings together some of the world leaders in this area of research who present a critical analysis of the ongoing research with respect to the effects and mechanisms of action of various types of mild stress, such as irradiation, heat, physical exercise, hypergravity, pro-oxidants and nutritional components, on a variety of biological systems ranging from fruitflies to human cells and bodies. Their separate chapters and a final collective chapter open up a whole new world of possibilities for future research in aging, successful aging, and health span extension.

Migration and Discrimination : IMISCOE Short Reader

This book provides a state of the art overview of the discrimination research field, with particular focus on discrimination against immigrants and their descendants. It covers the ways in which discrimination is defined and conceptualized, how it is measured, how it may be theorized and explained, and how it might be combated by legal and policy means.

Migraine

Migraine is a chronic paroxysmal neurological disorder characterised by multiphase attacks of head pain and a myriad of neurological symptoms. The underlying genetic and biological underpinnings and neural networks involved are coming sharply into focus. This progress in the fundamental understanding of migraine has led to novel, mechanism-based and disease-specific therapeutics. In this Seminar, the clinical features and neurobiology of migraine are reviewed, evidence to support available treatment options is provided, and emerging drug, device, and biological therapies are discussed.

Middleware 2005 ; ACM/IFIP/USENIX 6th International Middleware Conference, Grenoble, France, November 28 - December 2, 2005, Proceedings

Today, middleware is a key part of almost any application. Gone are the days when middleware was only used in the IT industry for high-end applications. Rather than middleware being part of the IT world, today IT applications r- resent only one aspect of middleware. With the increase in distribution, network capacity, and widespread deployment of computing devices (in homes, auto- biles, mobile phones, etc.), middleware has surpassed the importance of operating systems as the platform where application development and deployment take place. This makes middleware very exciting as a research area but also a very challenging one since it encompasses many different concepts and techniques from a wide varietyof ?elds: networking, distributed systems, softwareengine- ing, performance analysis, computer architecture, and data management. Middleware 2005 in Grenoble, France, was the 6th edition of an increasingly successfulconference.The scope of the conference has been slowly widening with every edition to accommodate new ?elds and applications.

Microwave Radiometry of Vegetation Canopies

Research into microwave radiation from the Earth’s surface in the presence of vegetation canopies, as well as the development of algorithms for retrieval of soil and vegetation parameters from microwave radiometric measurements, have been actively conducted for the last 30 years by scientific groups worldwide. The capability of the microwave radiometric method to determine soil moisture and vegetation biometric indices was revealed 25 years ago by the author and his colleagues. Soil moisture and vegetation covers play a key role in the hydrological cycle and in water and energy transfer on the border of land surface and atmosphere through evaporation and transpiration. Accomplishment of large international projects shows that microwave radiometry of soil and vegetation has become an instrument of practical application and operational use. A systematic account of questions concerning the microwave radiometry of the Earth’s surface in the presence of vegetation canopies is the main objective of the book.
