Dynamic bandwidth allocation with SLA awareness for QoS in ethernet passive optical networks [PDF]
, 2013 Quality-of-service (QoS) support in Ethernet passive optical networks is a crucial concern. We propose a new dynamic bandwidth allocation (DBA) algorithm for service differentiation that meets the service-level agreements (SLAs) of the users.

Electrochemically Driven Dissipative Growth of Affinity Hydrogels for Bioresponsive Interfaces
Advanced Functional Materials, EarlyView.Voltage pulses drive the growth and reinforcement of hydrogel films under dissipative conditions. This biocompatible strategy enables efficient integration of affinity ligands into the hydrogel matrix, enhancing the selective capture of growth factors and allowing precise temporal control over their release, making them well‐suited as adaptive ...

CMOS variable transconductance circuit with constant bandwidth
Electronics Letters, 1989 The authors propose a new linear CMOS transconductor circuit. It has a transconductance linearly variable by a gate voltage and a rather high bandwidth. Moreover, this bandwidth remains constant when the transconductance is varied. The circuit exploits the square-law characteristic of MOS transistors biased in saturation.< >

CLEX: Yet Another Supercomputer Architecture? [PDF]
, 2016 We propose the CLEX supercomputer topology and routing scheme. We prove that CLEX can utilize a constant fraction of the total bandwidth for point-to-point communication, at delays proportional to the sum of the number of intermediate hops and the ...
