High-aspect-ratio nanoimprinted structures for a multi-pole magnetic scale [PDF]
清華大學學生國際會議獲獎論文:徐志豪HARMNST 2013 Poster Award[[abstract]]Conventional non-structured magnetic scales can only achieve a pole pitch of around 1 mm by dedicate magnetization process; a smaller magnetic pole pitch yields a higher resolution.

The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

A number of different structures in industrial facilities are installed on supports. There is the case that the damage occurs by the coupled vibration. The response magnification is obtained from the modal natural frequency and the modal damping ratio of the coupled system in the seismic design.

Are sex ratio distorting endosymbionts responsible for mating system variation among dance flies (Diptera: Empidinae)? [PDF]
Maternally inherited bacterial endosymbionts are common in many arthropod species. Some endosymbionts cause female-biased sex ratio distortion in their hosts that can result in profound changes to a host's mating behaviour and reproductive biology. Dance

Performance enhancement of normal contact ratio gearing system through correction factor
As lined, higher transmission ratio drives system will have uneven stresses in the root region of the pinion and wheel. To enrich this agility of uneven stresses in normal-contact ratio (NCR) gearing system, an enhanced system is desirable to be ...

We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Image compression system with an optimisation of compression ratio
The fundamental goal of image data compression is to set an optimal compression ratio while maintaining an acceptable reproduction quality. This study describes the principles of design of image compression system that automatically sets an optimal compression ratio for particular image content by identifying the image compression method while ...

Low-frequency torsional resonance arising from large inertia load and elastic shaft causes vibration when industrial servo system is working, which degrades the system's performance of motion control.

Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Positive periodic solution for ratio-dependent $n$-species discrete time system [PDF]
summary:In this paper, sharp a priori estimate of the periodic solutions is obtained for the discrete analogue of the continuous time ratio-dependent predator-prey system, which is governed by nonautonomous difference equations, modelling the dynamics of
