In Barbie, Ken struggles with identity, feeling like he exists in Barbie’s shadow. He wants recognition, but for most of the movie, he’s “just Ken.” Many cybersecurity specialists can relate.

Researchers have developed a novel soundproofing panel using 3D-printed labyrinthine metamaterials. Experimental validation confirms its effectiveness in absorbing low-frequency noise (1 kHz). The modular, lightweight design could revolutionize noise control in various industries, offering a thinner and more efficient alternative to traditional soundproofing materials.

A numerical study tested enhancements to a 3D-printed acoustic panel, including melamine foam and a backing cavity. Adding foam shifted absorption peaks to lower frequencies, improving low-frequency attenuation, while foam-filled cavities created a more uniform absorption across frequencies. Results offer insights into optimizing noise reduction for different needs.

Taiko and DoraHacks are spearheading the biggest anonymous community vote ever conducted in Web3. The initiative aims to advance decentralization in community governance through the Taiko Grant Factory Hackathon. At the core of this vote is Minimal Anti-Collusion Infrastructure (MACI), a privacy-preserving and collusion-resistant voting mechanism.

A 3D-printed acoustic panel was tested in a reverberation room using ISO 354 standards. Results showed near-ideal sound absorption between 800-1300 Hz, aligning well with analytical and numerical predictions. Some discrepancies at higher frequencies (above 3 kHz) may be due to non-normal sound wave incidence.

A noise-absorbing panel was fabricated using selective laser sintering (SLS) to achieve precise labyrinthine structures. Additional openings were included to remove excess material, then sealed for accurate acoustic testing. A finite element (FE) model was created to analyze the panel’s structure and performance.

While aggressive managers are difficult, they aren’t impossible to work with. With the right strategies, you can turn them around.

In this introductory blog post, I showed a small fraction of what you can do. I encourage you to leverage its power if faced with heterogeneous development environments.

Researchers tested 3D-printed labyrinthine unit cells using an impedance tube to measure sound absorption efficiency (100-5000 Hz). The study followed ISO 10534-2 and ASTM E1050-19 standards, ensuring accuracy and reproducibility. Results confirmed that the unit cells effectively absorb sound through controlled energy dissipation and structural tuning.

Researchers developed a 3D-printed noise-absorbing panel using labyrinthine metamaterials. The design leverages space-coiling structures to enhance mid-to-low frequency sound absorption (800-1400 Hz) while maintaining a lightweight, modular form. Experimental tests confirmed near-ideal absorption in a reverberation room, offering a new approach to efficient and adaptable noise mitigation solutions.

Artificial Intelligence (AI) is no longer a futuristic concept confined to research labs and high-tech corporations. As AI’s influence grows, so do the disparities in who has access to its transformative potential. "Democratizing AI" is about breaking down barriers so that everyone can harness its power.

Since language is connected with human carbon-based consciousness, and AI has a conversational and relatable language capability, could that be evaluated as a fraction of consciousness? Language, by AI, does not mean it has feelings or emotions, but for the fraction that language represents in the total of human consciousness, per moment, could that fraction be compared to what AI might have and how...

Personal genotyping can illuminate what you might be doing wrong in the fertility optimization department. This is NOT a replacement for a doctor’s guidance on your parenting journey. If your genome sequencing turns up an infertility-associated condition, it may or may not be something you're affected by.

Researchers analyzed labyrinthine unit cells using a first-iteration Wunderlich curve design, modeling thermo-viscous losses to optimize sound absorption. By balancing energy leakage and structural losses, the study demonstrated how critical coupling enhances absorption efficiency. The design leverages narrow tube acoustics and JCA modeling for precise tuning.

Here, we replicate Table 4, but instead of pre-FNC/MSNBC era newspaper endorsements, we distinguish observations by the county-level Republican vote share terciles

A relevant question is whether the effects of contagious slant are driven by supply or demand – that is, a direct influence on news producers, or else theirs response to changes in reader preferences.

In Table C.14, re-run our main specification, but instead of bigram-based similarity with FNC, we regress vocabulary size (normalized by the total size of the corpus, column 1), average word length (column 2), average sentence length (column 3), and average article length (column 4) on instrumented FNC viewership relative to MSNBC and CNN.
