Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response
Laser &Photonics Reviews, EarlyView.A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands
Laser &Photonics Reviews, EarlyView.E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.

O-ODM Framework for Object-Relational Databases
International Journal of Interactive Multimedia and Artificial Intelligence, 2012 Object-Relational Databases introduce new features which allow manipulating objects in databases.At present, many DBMS offer resources to manipulate objects in database, but most application developers just map class to relations tables, failing to ...

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects
Laser &Photonics Reviews, EarlyView.A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Movement Disorders Clinical Practice, EarlyView.Abstract Background Parkinson's Disease (PD) is a progressive neurodegenerative disorder primarily characterized by motor symptoms such as tremors, rigidity, and bradykinesia. Structural brain changes, including atrophy in the midbrain, basal ganglia, and cortical regions such as the frontal and temporal lobes, are observed in advanced stages.

Cluster-based DBMS Management Tool with High-Availability [PDF]
Journal of Systemics, Cybernetics and Informatics, 2005 A management tool which is needed for monitoring and managing cluster-based DBMSs has been little studied. So, we design and implement a cluster-based DBMS management tool with high-availability that monitors the status of nodes in a cluster system as ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Patients with cardiac implantable electronic devices (CIEDs) may receive replacement device components over time, resulting in mixed‐manufacturer systems that pose unknown, potentially higher risk under MRI exposure. It is not clear how to efficiently evaluate whether adding a non‐original implantable pulse generator (IPG) changes the ...
