  2. 40 percent of fMRI signals do not correspond to actual brain activity from tum.de
    152 by geox 2h ago | | |

    Article: 7 min

    A new study published in Nature Neuroscience reveals that 40% of MRI signals do not correspond to actual brain activity, challenging the long-standing assumption that increased blood flow is always accompanied by higher oxygen demand and neuronal activity. Researchers from TUM and FAU found that regions with elevated activity can meet their energy demands without requiring greater perfusion.

    • Increased fMRI signal does not always indicate increased blood flow or neuronal activity.
    • The findings could lead to opposite interpretations in many existing fMRI studies.
    Quality:
    The article provides clear, concise information on the study's findings and implications.

    Discussion (62): 19 min

    The comment thread discusses various opinions and arguments regarding the reliability, validity, and interpretation of fMRI studies. Opinions range from concerns about statistical abuse and poor test-retest reliability to support for its use as a tool for imaging soft tissues and measuring blood flow. The conversation also touches on emerging topics like comparisons with other imaging techniques and the impact of psychedelics on brain activity measurement.

    • fMRI is prone to statistical abuse
    • The BOLD response has been well-accepted in neuroscience, but its interpretation with respect to cognition is unclear
    • fMRI studies are unreliable and border on pseudoscience due to poor test-retest reliability
    Counterarguments:
    • fMRI is a useful tool for imaging soft tissues and measuring blood flow as a proxy for brain activity.

  4. Rust GCC back end: Why and how from blog.guillaume-gomez.fr
    63 by ahlCVA 2h ago | | |

    Article: 18 min

    Explains the concept of Rust compiler backends, focusing on the GCC backend. It discusses how compilers work in general and differentiates between front-end and back-end processes. The post highlights the importance of having a GCC backend for supporting older processors like Dreamcast and introduces gccrs as an alternative front-end for GCC.

    The article provides insights into the technical aspects of compiler design, which can influence software development practices and contribute to advancements in programming languages.

    Discussion (30): 6 min

    The comment thread discusses the intentional modularization of GCC to prevent non-free projects from building on top of its components, contrasting it with LLVM's architecture. The discussion also touches upon the role of parser generators in modern compilers and the impact of licensing choices on software development.

    • LLVM was created as a response to GCC's lack of modularization
    Counterarguments:
    • LLVM wasn't the first modularization of codegen, see Amsterdam Compiler Kit for prior art
    • Even clang with all the LLVM modularization is going to take a couple of years to move from plain LLVM IR into MLIR dialect for C based languages

  7. I don't think Lindley's paradox supports p-circling from vilgot-huhn.github.io
    28 by speckx 2h ago | |

    Article: 35 min

    The article discusses p-value circling and Lindley's paradox in the context of statistical hypothesis testing. It explores the justification behind scrutinizing p-values close to the conventional threshold of 0.05, particularly when considering questionable research practices like p-hacking. The author argues that while p-values can be indicative of potential issues with study design or data manipulation, they should not be solely relied upon for evidence against the null hypothesis.

    • The article critiques the use of an arbitrary p-value threshold (e.g., 0.05) and discusses the practice of 'p-value circling' where researchers pay extra attention to significant results that are close to this threshold.
    • It explores how Lindley's paradox can be used as a justification for scrutinizing p-values near the threshold, suggesting that such values might indicate an effect size that is more likely under a specific alternative hypothesis than under the null hypothesis.
    • The author argues against interpreting p-values as direct evidence of statistical malpractice or questionable research practices and emphasizes the importance of contextualizing them within the study's power and other features.
    Quality:
    The article provides a detailed analysis of p-value circling and Lindley's paradox, offering insights into statistical hypothesis testing without presenting any personal biases or opinions.

    Discussion (4):

    The comment thread discusses the article's approach to statistical analysis, particularly in relation to Lindley’s paradox and p-circling. There is a debate on whether the presented concept of Lindley’s paradox aligns with traditional understanding. The discussion also touches upon power analysis and choosing alpha-levels.

    • One could specify a smallest effect size of interest and compare it with p-values
    • Mixing paradigms that aren't designed to be mixed can lead to paradoxes in statistical analysis
    Counterarguments:
    • The author's usage of Lindley’s paradox seems unrelated to the traditional understanding as described by Wikipedia
