Optical fibers are particularly well suited for long-distance data transmission, as the attenuation losses are significantly lower than e.g. when using copper conductors. Scientists at the University of Stuttgart have now developed a simple and flexible method of joining solid- and hollow-core fibers that is characterized by low coupling losses and easy and flexible handling. In particular, it is suitable for liquid-filled hollow-core fibers. The method enables a durable, low-loss connection of fibers of different diameters without the application of heat required.
The invention describes a waste safeguard for forming processes, which is using locally applied vibrations to avoid a slug pulling. Implementing this technology increases the operating speed and improves the quality of the machined part. The technology is flexible in use and can be integrated in different forming processes and tools.
“Our new method using microwaves can propagate through all types of tissues and target deeply situated tumors,” said Wei Chen, UTA professor of physics and…
Researchers of the University Medical Center of Aachen have developed a blood-based diagnostic test for breast cancer and its pre-cancerous stages, based on the grade and intensity of CpG promoter methylation of early breast cancer biomarkers, i.e. the genes SPAG6, NKX2-6 and PER1 (the “SNP panel”). Combined, these three genes provide an opportunity to easily test for breast cancer, starting from a patient’s blood sample (Liquid biopsy). It is very likely that a blood-based test would increase compliance of women to participate in medical prevention of breast cancer. In addition, this concept may allow to broaden prevention to elderly women (>70 years) who currently are not invited to mammography screening.
In April 2016, a blood-based early detection system for colon cancer (the Epi ProColon test by Epigenomics AG) has been approved by the FDA. The RWTH Aachen blood test could be applied in an analogous way for breast cancer detection. Both tests have similar sensitivity and specificity, which may qualify the herein presented test for approval as well. A key argument for the approval of the Epi proColon test by the FDA has been the likelhood of increased acceptance by the relevant population thus reinforcing screening participation.

A special process to coat SiO2 nanoparticles around with biocidal quaternary ammonium silanes has been achieved, so that the biocidal moiety points always outwards. Subsequently, the nanoparticles can be deposited on one surface from a dispersion of a simple solvent (for example alcohol). The forming surface coating acts purely contact active antimicrobial. That means, when touching, no toxic substances go over the contacting body. The new SiO2 nanoparticles are suitable for the antimicrobial coating especially in sanitary and wet areas, for example, of silicone joints. However, all surfaces in principle can be coated with them.
The invention relates to a spin torque magnetic flip flop and a shift register incorporating such, enabling high operation speed, non volatility and reducing die space consumption .
