Energy conserved time-synchronization technique in wireless sensor networks

, 2011
碩士時間同步(Time Synchronization)為無線感測網路(Wireless Sensor Network)中一重要的研究議題，諸如物體移動的追蹤、視覺影像的監控與比對或是利用TDMA的MAC排程等，都必須在時間同步的條件下進行。傳統的時間同步技術主要是討論感測器之間如何進行對時，使得感測器之間能夠有效的達到時間同步。然而，這類文獻的控制封包過多，且未考量時間同步的精準度與事件發生之時限關係，因此，這類文獻會有網路負載量過大及電量消耗過多的問題。本論文針對這些問題提出一時間同步技術 ...

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

Advanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Piezoelectric Surface Charge and Dynamic Stimulation Synergize to Promote Cardiac Myoblast Alignment and Maturation

Advanced Healthcare Materials, EarlyView.
Surface polarization of PVDF films combined with mechanical stimulation generates piezoelectric electrical cues that modulate cardiomyoblast behaviour. Non‐poled and poled PVDF substrates provide distinct electroactive microenvironments influencing cell adhesion, proliferation, and differentiation.
