Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response

open access: yesAdvanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...

The question "Are We Alone?" in different cultures

open access: yes, 2009
A survey of the worldwide litterature reveals that the question "Are We Alone in the Universe?" has been formulated only in the western litterature. Here I try to understand why it is so.

Autonomous Planetary Rover Navigation and Crater‐Based Map Augmentation for Path Planning and Rock Localization Using Space ROS

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Autonomous planetary rovers operate in GPS‐denied, low‐texture, crater‐rich environments where traditional SLAM‐based navigation systems suffer from localization drift and unreliable obstacle handling. To address these challenges, this work proposes a Space‐ROS–based autonomous navigation framework integrating ROS2 with the NAV2 stack, RTAB‐Map visual ...

Time Markers for SETI in Binary Systems: History and Prospects

open access: yesAstronomy
Contemporary surveys in the search for extraterrestrial intelligence (SETI) typically make one-off “spot scans” across the sky to search planetary systems for narrow-band radio signals that would indicate the presence of intelligent life.

A Stochastic Process Approach of the Drake Equation Parameters

open access: yes, 2011
The number N of detectable (i.e. communicating) extraterrestrial civilizations in the Milky Way galaxy is usually done by using the Drake equation. This equation was established in 1961 by Frank Drake and was the first step to quantifying the SETI field.

Algorithmic Communication with Extraterrestrial Intelligence [PDF]

open access: yesSymposium - International Astronomical Union, 2004
ACETI (algorithmic communication with extraterrestrial intelligence) builds upon mathematical languages to create a general purpose programming language. While the underlying framework may be quite simple, the programs derived from even a small instruction set, when run on a sufficiently fast computing substrate, may interact with their users in real ...

Hybrid Strategy for Coordinated Interstellar Signaling: Linking the Galactic Center and Extragalactic Bursts

open access: yesThe Astrophysical Journal
The search for extraterrestrial intelligence (SETI) is largely limited by the vastness of the signaling parameter space. The concurrent signaling scheme offers a framework in which civilizations can coordinate their transmission and reception by ...

Bayesian approach to SETI

open access: yes, 2018
The search for technosignatures from hypothetical galactic civilizations is going through a new phase of intense activity. For the first time, a significant fraction of the vast search space is expected to be sampled in the foreseeable future ...
