The Quest for Universal Spectral Libraries: Standards, Metadata, and Machine Readability This tutorial examines the development of universal spectral libraries, reviewing standardization efforts, mathematical frameworks, and practical examples across multiple spectroscopies, while emphasizing metadata harmonization, FAIR principles, and the emerging role of AI in building interoperable, machine-readable repositories. This remains an unsolved problem in spectroscopy. https://lnkd.in/gGbqzGwN

New in TOCHI: Just Accepted “Mediating Human-Nature Relations Through Technology: A Scoping Review of Post-Anthropocentric Artifacts and Their Design Strategies” By Madlen Kneile, Judith Dörrenbächer, Marc Hassenzahl, and Matthias Laschke 📄 Read the paper: https://lnkd.in/df4_JP9C How can design go beyond centering the human, and instead foster richer, more ethical relationships between people and nature? This scoping review explores exactly that. The authors analyze 70+ artifacts and surface seven design strategies for post-anthropocentric technology design: → Systems that encourage care, reciprocity, and humility toward the natural world → Design that foregrounds interdependence, not domination 💡 A key reflection: Studying “nature” in design isn’t just technical or ecological: it’s deeply cultural, philosophical, and personal. Understanding your own worldview may be as challenging (and rewarding) as the research itself. A thoughtful and timely contribution to the growing conversation around ecological HCI and more-than-human futures. #ACMTOCHI #HCI #DesignResearch #Sustainability #PostAnthropocentric #NatureTech #HumanNatureInteraction

A recent study published in *Nature* delves into the intricate role of the dorsomedial prefrontal cortex (dmPFC) in shaping complex fear associations. Unlike the amygdala, which is known for simpler fear conditioning, the dmPFC appears to integrate multiple sensory cues associated with aversive experiences, revealing a more nuanced understanding of emotional processing. Through calcium imaging and advanced behavioral paradigms, researchers demonstrated that dmPFC neurons not only respond to direct threats but also link indirect cues, such as visual and auditory signals, to the emotional weight of an experience. This suggests that the dmPFC is crucial for making complex inferences about fear, a function that could have significant implications for treating neuropsychiatric disorders like PTSD and anxiety. As we advance our understanding of these neural mechanisms, the potential for targeted therapies—such as transcranial magnetic stimulation and deep brain stimulation—becomes more tangible. This study provides a foundational insight into the neural circuits that underpin our emotional responses, paving the way for innovative approaches to mental health treatment.

CppCon, The C++ Conference 2025 September 14-19th, Aurora, Colorado Preview: Hui Xie: "Implement Standard Library: Design Decisions, Optimisations and Testing in Implementing Libc++" https://sched.co/27bNw This presentation covers various practical examples in the designs, optimisations and testing in libc++, a standard library implementation. In space optimisation section, it presents various examples of using compact type, reusing tail padding bytes, reusing unused bits in existing bytes, in various standard types: std::stop_token , std::expected , std::optional , std::variant , std::ranges library and std::move_only_function . In time optimisations section, it presents examples of how we optimise std::atomic<T>::wait 's waiting strategy, how we optimised algorithms for segmented iterators, and also how we keep in mind optimisations by leaving the door open for future optimisations. At the same time, compilation time is also important so it also contains examples how unnecessary template instantiations can be avoided. Finally, this talk covers the unit tests of libc++, including the high test coverage of standard spec, the technic we share tests between runtime and constexpr, negative testing and so on.
