The first Mobile IP PDA for seamless access demonstrated by a member of the EURESCOM project team
+++ EURESCOM for the first time demonstrates seamless access with a PDA. +++
Premiere at the EURESCOM workshop `Wireless Access` in Heidelberg on 12 March: The EURESCOM project on `Bluetooth Access` presented the first PDA, which can seamlessly connect to different access networks, like LAN, Bluetooth, Wireless LAN, and GPRS.
In co-operation with the software company Birdstep from Norway and access point supplier Patria Ailon from Finland, the European project team implemented Mobile IP on a PDA with the operating system Pocket PC 2002. The Mobile IP PDA has a built-in priority mechanism for selecting automatically the best available network access.
Seamless handover between networks is especially convenient for downloading large volumes of data, explains Josef Noll: "Let us assume, I am on the move with my PDA. Via GPRS my e-mails will always be updated, but downloading large attachments, like video files, might take too long with GPRS. But as soon as I get close to a Bluetooth network, which has much more capacity, the download can immediately begin, without re-configuring the PDA."
Mr Noll expects PDAs with seamless access, based on Mobile IP, to be available for corporate customers by the end of 2002 and for private users by the end 2003. He is convinced that after EURESCOM`s first successful demonstration of seamless access, others in the telecommunications domain will follow in developing Mobile IP-based devices.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
