• ### Laser-Tissue Interactions Fundamentals and Applications

I like playing around with words and letters. You probably know that LASER is an artificial word derived from “Light Amplification by Stimulated Emission of Radiation”. When starting my lecture on “Laser–Tissue Interactions” I tend to write this derivation on the board. I continue with “LIGHT: Lasers Irradiate Germinated and Healthy Tissues”. Why? Lasers cut everything, if appropriate laser parameters are selected. There is no shield around healthy tissue. And there is no laser that fits all sizes as some clothes do. Lasers never have been some kind of wonder instruments.

• ### NEWTONIAN MECHANICS- Schaum's College Physics

A vector is a quantity that possesses both magnitude and direction. Examples of vector quantities are displacement, velocity, acceleration, and force. A vector quantity can be represented by an arrow drawn to scale. The length of the arrow is proportional to the magnitude of the vector quantity. The direction of the arrow represents the direction of the vector quantity.physics in general is the most scientific study of "physical" and "interaction".

• ### E-LEARNING – ENGINEERING, ON-JOB TRAINING AND INTERACTIVE TEACHING

The first application in Section 3, bone healing, may be surprising as a fluid mechanics topic. One generally thinks of bone as a solid material, but much of the bone content is fluid. Fluid mechanics therefore plays an important role in the analysis, and the results depend on the choice of the constitutive equation.

• ### Chapter 114. Molecular Mechanisms of Microbial Pathogenesis (Part 5)

Numerous virus–target cell interactions have been described, and it is now clear that different viruses can use similar host-cell receptors for entry. The list of certain and likely host receptors for viral pathogens is long. Among the host membrane components that can serve as receptors for viruses are sialic acids, gangliosides, glycosaminoglycans, integrins and other members of the immunoglobulin superfamily, histocompatibility antigens, and regulators and receptors for complement components.

• ### Chapter 114. Molecular Mechanisms of Microbial Pathogenesis (Part 8)

GPI-anchored receptors do not have intracellular signaling domains. Instead, the mammalian Toll-like receptors (TLRs) transduce signals for cellular activation due to LPS binding. It has recently been shown that binding of microbial factors to TLRs to activate signal transduction occurs not on the cell surface, but rather in the phagosome of cells that have internalized the microbe. This interaction is probably due to the release of the microbial surface factor from the cell in the environment of the phagosome, where the liberated factor can bind to its cognate TLRs.

• ### ARCHITECTURAL ENGINEERING DESIGN: MECHANICAL SYSTEMS

• ### Chapter 114. Molecular Mechanisms of Microbial Pathogenesis (Part 3)

Viral Adhesins (See also Chap. 161) All viral pathogens must bind to host cells, enter them, and replicate within them. Viral coat proteins serve as the ligands for cellular entry, and more than one ligand-receptor interaction may be needed; for example, HIV uses its envelope glycoprotein (gp) 120 to enter host cells by binding to both CD4 and one of two receptors for chemokines (designated CCR5 and CXCR4). Similarly, the measles virus H glycoprotein binds to both CD46 and the membrane-organizing protein moesin on host cells.

• ### Mechanical Systems, Classical Models

All the phenomena of nature are characterized by motion; this is an essential property of matter, having infinity of aspects. For instance, the motion can be mechanical, physical, chemical and biological; there correspond various sciences of nature. Among them, mechanics studies the objective laws of the mechanical motion of material bodies, the simplest form of motion of matter; we will deal with such a study in what follows. The scientific study of matter has put in evidence its existence in the form of physical systems.

• ### Chapter 113. Introduction to Infectious Diseases: Host–Pathogen Interactions (Part 4)

The Immune Response Innate Immunity As they have co-evolved with microbes, higher organisms have developed mechanisms for recognizing and responding to microorganisms. Many of these mechanisms, referred to together as innate immunity, are evolutionarily ancient, having been conserved from insects to humans. In general, innate immune mechanisms exploit molecular patterns found specifically in pathogenic microorganisms. These "pathogen signatures" are recognized by host molecules that either directly interfere with the pathogen or initiate a response that does so.

• ### HUMAN MACHINE INTERACTION – GETTING CLOSER

In this book, the reader will find a set of papers divided into two sections. The first section presents different proposals focused on the human-machine interaction development process. The second section is devoted to different aspects of interaction, with a special emphasis on the physical interaction.

• ### Lowcost Communication for Rural Internet Kiosks Using Mechanical Backhaul

Rural kiosks in developing countries provide a variety of services such as birth, marriage, and death certificates, electricity bill collection, land records, email services, and consulting on medical and agricultural problems. Fundamental to a kiosk’s operation is its connection to the Internet. Network connectivity today is primarily provided by dialup telephone, although Very Small Aperture Terminals (VSAT) or long-distance wireless links are also being deployed. These solutions tend to be both expensive and failure prone.

• ### Báo cáo khoa học: Interactive Group Suggesting for Twitter"

The number of users on Twitter has drastically increased in the past years. However, Twitter does not have an effective user grouping mechanism. Therefore tweets from other users can quickly overrun and become inconvenient to read. In this paper, we propose methods to help users group the people they follow using their provided seeding users. Two sources of information are used to build sub-systems: textural information captured by the tweets sent by users, and social connections among users.

• ### Báo cáo Y học: Investigations into the mechanisms used by the C-terminal anchors of Escherichia coli penicillin-binding proteins 4, 5, 6 and 6b for membrane interaction

Escherichia colilow molecular mass penicillin-binding pro-teins (PBPs) include PBP4, PBP5, PBP6 and PBP6b. Evi-dence suggests that these proteins interact with the inner membrane via C-terminal amphiphilica-helices. Nonethe-less, the membrane interactive mechanisms utilized by the C-terminal anchors of PBP4 and PBP6b showdifferences to those utilized by PBP5 and PBP6. Here, hydrophobic moment-based analyses have predicted that, in contrast to the PBP4 and PBP6b C-termini, those of PBP5 and PBP6 are candidates to form oblique orientateda-helices....

• ### MECHANICAL RECYCLING OF PVC WASTES

This section illustrates that MBT systems can be described as two simple concepts: either to separate the waste and then treat; or to treat the waste and then separate. In some systems only biological treatment is required to treat all the residual MSW before disposal to landfill. Whilst a variety of treatment and mechanical separation options are offered, these need to be optimised in terms of the outputs in order to find outlets for the various materials / fuels derived from the process (see Markets for the Outputs section). ...

• ### Báo cáo khoa học: "REAPING THE BENEFITS OF INTERACTIVE AND SEMANTICS*"

Semantic feedback is an important source of information that a parser could use to deal with local ambiguities in syntax. However, it is difficult to devise a systematic communication mechanism for interactive syntax and semantics. In this article, I propose a variant of left-corner parsing to define the points at which syntax and semantics should interact, an account of grammatical relations and thematic roles to define the content of the communication, and a conflict resolution strategy based on independent preferences from syntax and semantics.
