Awesome universal chirp [PDF]

open access: yesScience, 2016
In 1978, while I was an undergraduate student, Kip Thorne came to Stanford University to give a seminar on a proposed search for gravitational waves. The auditorium quickly filled with experts and inquisitive students like me. As Thorne described a quest for these ripples in space-time, the audience grew palpably skeptical. Albert Einstein

Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

open access: yesAdvanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.

Sustained Self‐Powered Real‐Time Vibration Monitoring Through Integrated Nonlinear Harvesting and Energy‐Aware Wireless Sensing

open access: yesAdvanced Science, EarlyView.
A self‐powered vibration sensing platform integrates a quasi‐zero‐stiffness piezoelectric harvester, synchronized electric charge extraction, energy management, and wireless ADC acquisition. Ambient vibration is simultaneously harvested as energy and digitized as information, enabling sustained real‐time waveform monitoring without external power.

Performance of chirped-FSK and chirped-PSK in the presence of partial-band interference [PDF]

open access: yes2011 18th IEEE Symposium on Communications and Vehicular Technology in the Benelux (SCVT), 2011
To improve interference robustness of wireless communication, spread spectrum techniques are often used. We use the chirp spreading technique along with FSK and PSK binary modulation schemes to obtain interference robust radio communication. The performance of chirped-FSK and chirped- PSK modulation through a white gaussian noise channel is simulated ...

Dipolar Coupling Errors in Nuclear Spin Qubits

open access: yesAdvanced Science, EarlyView.
Multi‐nuclear spin registers of phosphorus‐atom qubits in silicon have demonstrated 99.99% single and >$>$99.9% two qubit gate fidelities. Despite nanometer separation, read‐out fidelities between individual nuclear spins within the register are not identical.
