1. Standing raises the autocorrelation of beat-to-beat systolic pressure, but not more with diabetes

   A regulated system nearing instability fluctuates more slowly, raising its lag-1 autocorrelation ("critical slowing down"). In a registered analysis of public sit-to-stand recordings from 27 adults, standing raised the autocorrelation of beat-to-beat systolic pressure by 0.0431 (CI 0.0066 to 0.0761). The rise was not larger with diabetes (probability of a larger rise 0.505, CI 0.2802 to 0.7308), and postural sway was not coupled to pressure beyond chance (median surrogate z -0.028). Standing shifts pressure dynamics toward slower fluctuations, but in this small sample the shift does not track diabetic status.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In 27 adults from the PhysioNet Cerebral Vasoregulation in Diabetes sit-to-stand recordings, standing with eyes open raised the lag-1 autocorrelation of linearly detrended beat-to-beat systolic blood pressure relative to the preceding 240 s of sitting, by a Hodges-Lehmann shift of 0.043 (bootstrap 95% CI 0.007 to 0.076), with 19 of 27 participants rising (one-sided Wilcoxon signed-rank p = 0.012; Holm-adjusted across two primary tests p = 0.025).
   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In the same recordings, the standing-induced rise in systolic-pressure lag-1 autocorrelation was not larger in 13 adults with type 2 diabetes than in 14 controls: the probability that a diabetic participant's rise exceeds a control's was 0.505 (bootstrap 95% CI 0.28 to 0.73; one-sided Mann-Whitney p = 0.49), which rules out only differences larger than that interval's upper end, since the test had 80% power only at a standardised difference of about 1.0.

2. Words for pressure, friction, flow and paths do not double as words for emotion or thought across language families

   Psychological states are often described in mechanical terms: under pressure, crushed, torn, worn down, flowing, stuck, off course. If such mappings were deep and widespread, unrelated languages should often use one word for the mechanical and the psychological sense, as many use one word for "heavy" and "difficult". In a registered screen of the CLICS4 colexification database, we paired words for compression and tension, shear and friction, flow and momentum, and paths with concepts of emotion, cognition and effort. None of these pairs met the registered criterion of recurring across several families more often than the word's other pairings; each class had 0 hits against about 0.477 to 0.719 expected for random concepts. Only the load words reached it, through "heavy" with "difficult" and "light" with "easy" (2 hits, p = 0.0633). Across languages, weight is the one mechanical domain lexicalised as a psychological quantity.

   • Published, Reproduced.Published, Reproduced: Across CLICS4 v1.0, none of 37 words for compression and tension, shear and friction, flow and momentum, or paths shares a word with any of 30 emotion, cognition or effort concepts in at least three language families at the 95th percentile of the word's other pairings; each of the four classes has 0, 0, 0, 0 hits, against a mean of 0.48 to 0.72 for random concept sets of the same size.
   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: Weight words are the exception: 'heavy' and 'light (weight)' give 2 hits among five load words (with 'difficult' and 'easy'), against 0.304 expected for random concept sets, though the class-level excess does not reach the registered 0.05 level (p = 0.0633), so the class test has limited sensitivity.

3. Mechanical cancer studies test different stages, and tumor-cell suppression does not measure primary prevention

   Does maintaining normal tissue mechanics prevent cancer initiation? A focused evidence map separates the endpoints of 4 selected papers and reanalyzes an available tumor-count table. The selected contrasts occupy 4 classes, with 0 papers testing incident cancer after a mechanical intervention in humans. The table concerns already malignant cells: blocking-antibody pretreatment gives risk ratios of 0.4667 and 0.5 against its controls. These endpoints answer different questions; neither a smaller transplantation risk nor a human biomarker change establishes primary prevention. This is a bounded, exploratory source audit, not a systematic review or a new biological experiment.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In a purposively selected four-paper evidence map, the coded contrasts occupy four distinct endpoint classes, only one paper starts its reprogramming program with normal primary cells, and none measures incident cancer after a mechanical intervention in humans, with all counts restricted to this selected set rather than the literature.

4. Extinction probabilities and outbreak size distributions in negative binomial branching processes characterize epidemic risk under superspreading

   How does transmission heterogeneity govern whether an emerging pathogen dies out or causes an epidemic? In negative binomial branching processes at reproduction number 2.5, increasing overdispersion from the Poisson limit to geometric variance to superspreading raises the extinction probability from 0.107355 to 0.4 to 0.860685. Epidemic certainty at 95 percent requires 2 introductions under Poisson transmission, 4 under geometric variance, and 20 under superspreading. Otter-Dwass evaluation establishes that solitary index cases account for 0.721943 extinction probability, or 83.88 percent of extinctions. Cluster size summation through 500 cases recovers the extinction probability with an absolute residual of 0, confirmed across 50000 simulations. Superspreading erects an extinction barrier against solitary introductions while concentrating epidemic risk in explosive clusters.

5. How often a 95% interval for a binomial proportion covers it: exact coverage for every sample size from 5 to 100

   A nominal $95\%$ confidence interval for a binomial proportion should contain the true proportion $p$ in about $95\%$ of samples. Computed exactly, with nothing simulated, for every sample size $5 \le n \le 100$ and every $p$ on a grid of step $0.001$, the textbook Wald interval covers $p$ less than $0.93$ of the time at a fraction 0.463088 of the 95904 $(n, p)$ pairs, and averages 0.88228. The Wilson score interval falls below $0.93$ at a fraction 0.032981 of them, and the Agresti-Coull interval at 0.003681. The Clopper-Pearson interval never covers less than $0.95$, but averages 0.970942, so it is wider than it needs to be. Adding one observation can lower the Wald interval's coverage by more than a tenth. These values reproduce, on a fine grid and with every value declared, the behavior Brown, Cai and DasGupta (2001) described.

6. Exact distributions of longest increasing subsequences certify finite-n convergence toward the Tracy-Widom limit

   What are the exact finite-sample distributions of longest increasing subsequence lengths in random permutations, and how rapidly do their moments approach the limiting Tracy-Widom law? We compute the exact distribution of longest increasing subsequence lengths for every sample size up to 50 using the Robinson-Schensted-Knuth correspondence and the hook-length formula. At the largest sample size, the exact expected length is 11.309389 with variance 1.94134, corresponding to a normalized centered mean of -1.475863 and normalized variance of 0.526961. Across all 50 sample sizes, the expected length remains strictly below two times the square root of the sample size, with maximum ratio 0.799695. Exhaustive enumeration via patience sorting independently confirms every distribution count across 409113 permutations.

7. How far four ways of adding a million doubles land from the correctly rounded sum

   Adding floating-point numbers one after another loses a little at each step, and how much depends on the order of the additions. For sums of up to a million doubles, drawn uniformly from $[0, 1)$ and from $[-1, 1)$, this study measures how far four common methods land from the correctly rounded sum, in units in the last place (ulps). Adding left to right, the error averages 196.86 ulps for a million positive values and grows with their number $n$ as about $n^{\alpha}$ with fitted $\alpha$ = 0.545, close to the square root that independent rounding errors predict. Pairwise summation stays within 2 ulps at every length. Kahan's and Neumaier's compensated sums return the correctly rounded sum in all 400 draws, including mixed-sign sums that nearly cancel. Every value is reproducible exactly, on any machine and Python version.

10. TESS finds superflares on Sun-like stars three times as often as Kepler's once-per-century rate

    How often do stars like the Sun release superflares of $10^{34}$ erg or more? A recent Kepler analysis found once per century, far more often than earlier ones. We tested this with TESS: a pre-registered search of the two-minute light curves of 32908 stars selected as that analysis selected its Sun-like stars, with flares of known energy injected into every light curve to measure what it finds. It counted 78 superflares where the once-per-century rate predicts 23.4: 3.33 times that rate (interval 2.63 to 4.15), one per 33 years per star, far above the earlier rates. Every planned subset and sensitivity analysis gives a ratio above one. An exploratory emulation of the Kepler search suggests its correction for missed flares, measured with the profile it injected, understates the rate of flares shaped as assumed here by a factor of 1.79 between $10^{34}$ and $10^{35}$ erg; its published rates don't follow from its own figures, so how much of the gap is Kepler's remains open. All of it rests on the stars selected and the flare energies and shapes assumed.

    • Published.Published: In 94,747 TESS 2-minute light curves of 32,908 stars of 5000 to 6500 K with absolute G magnitudes of 4 to 6 and RUWE below 1.4 (5,605 star-years), the pre-registered search, with its SAP test corrected after registration to require the uncorrected flux to rise, counted 78 flares of bolometric energy 10^34 erg or more where the rate Vasilyev et al. (2024) measured with Kepler predicts 23.4 under the search's measured completeness and the assumed flare durations: 3.33 times that rate (95% CI 2.63 to 4.15), about once per 33 years per star; the registered code counted 79 (3.37 times, 2.67 to 4.20).
    • Published.Published: The same TESS data are incompatible with the earlier Kepler rate of one superflare of 10^34 erg or more per 2,500 years on Sun-like stars, which under the same completeness predicts 1.04 counted flares where 78 were found (Poisson probability below 10^-100).
    • Published.Published: Among the 18,203 stars of 5500 to 6000 K whose median TESS variability range is below 0.3%, the 50 counted superflares are 3.63 times (95% CI 2.70 to 4.79) the 13.8 that the rate Vasilyev et al. (2024) give for their Sun-like stars predicts.

11. Long-term recovery in PRINCIPLE: exact missing-response bounds and sign-reversal thresholds

    Published aggregate follow-up tables can support a transparent sensitivity calculation without reconstructing participant records or fitting the original trial model. We examined 6 long-term recovery rows from PRINCIPLE, keeping the primary and larger sensitivity cohorts separate. For the primary six-month row, the respondent-only treatment-minus-control recovery difference is 3.071 percentage points. Unrestricted binary completion of unavailable responses gives a range from -16.54 to 21.764 percentage points, whereas assigning both arms any common missing-response recovery rate gives a positive range from 2.329 to 2.896 percentage points. These are conditional bounds, not confidence intervals. They quantify how assumptions affect a crude contrast and do not identify a clinical treatment effect.

    • Published.Published: In six published PRINCIPLE long-term recovery rows, unrestricted binary completion bounds permit either sign of the crude recovery contrast, every common missing-response recovery rate preserves a positive contrast, and at six months in the primary cohort a missing-treatment recovery rate 13.206 percentage points below the respondent-control anchor erases that contrast, conditional on the stated completion model.

12. Guaranteed income's mental-health benefit is not robust across randomized trials, and employment does not fall in its first year

    Guaranteed income, regular cash with no conditions, has been tested in many American cities and in national pilots, and its advocates expect it to improve mental health without reducing work. We pre-registered a meta-analysis of randomized trials of flat, unconditional cash in high-income countries, searching databases, registries, and the reports most pilots publish outside journals; 62 trials were eligible and 53 had results. About a year into payments, mental health was better in the cash arms by 0.09 standard deviations (CI 0.041 to 0.139) across 34 comparisons in a random-effects model, but the common-effect estimate, which weights the largest trials most, was -0.002 (-0.023 to 0.018), and smaller trials reported larger effects. Employment changed by 0.599 percentage points (-2.533 to 3.731), and the mental-health effect did not fade during payments. Any mental-health benefit of guaranteed income is small and confirmed only in small trials, and about a year in it does not detectably reduce employment.

    • Published, Reproduced.Published, Reproduced: In 34 comparisons from 32 randomized trials of recurring unconditional cash in high-income countries (16,834 people analysed), mental health about 12 months into payments was better in the cash arms by a pooled standardized mean difference of 0.090 (95% CI 0.041 to 0.139; Holm-corrected p = 0.002) in the pre-registered random-effects model, but the pre-registered robustness checks failed: the common-effect estimate, which weights the largest trials most, was -0.002 (-0.023 to 0.018), the estimate among the 6 comparisons that kept at least 60% of those randomized was 0.043 (-0.077 to 0.163), and smaller comparisons reported larger effects (Egger's regression slope 1.54, 95% CI 0.75 to 2.33; p < 0.001).

    • Published, Reproduced.Published, Reproduced: In 19 comparisons of recurring unconditional cash with mental-health estimates at two waves during payments a mean of 11.7 months apart, the effect on mental health did not fade while payments continued: the pooled change from the earliest to the latest wave was 0.000 standard deviations (95% CI -0.049 to 0.048; Holm-corrected p = 1.000), the effects at the two waves being 0.048 and 0.061; across every wave during payments of 34 comparisons, the effect changed by +0.015 standard deviations per year (-0.034 to 0.064).

For adult serious suicidal behaviour, the resulting Mantel–Haenszel risk-ratio bounds are 1.712 to 2.1962; for adult serious suicidality, 1.2154 to 1.8476. The corresponding pediatric bounds are 1.0045 to 1.4773 and 1.8144 to 2.8091. All remain above the null. Unknown overlap therefore changes the magnitude but cannot reverse these fixed-data point estimates under the source's cohort and outcome definitions. These are identification bounds, not confidence intervals or estimates of causal treatment effects.

    • Published, Reproduced.Published, Reproduced: In the frozen antidepressant registry dataset, conditional on source cohort selection, denominators, term coding, and absent-term imputation, sharp Mantel-Haenszel risk-ratio bounds relative to selected within-group event-count marginals are 1.7120261533 to 2.1961879882 for adult serious suicidal behaviour, 1.2154409158 to 1.8475901940 for adult serious suicidality, 1.0045047792 to 1.4773331886 for pediatric serious behaviour, and 1.8144436696 to 2.8090979871 for pediatric serious suicidality. Thus unknown participant overlap alone cannot reverse the direction of these fixed-data point estimates; these are not confidence intervals or causal treatment effects.

14. Mass azithromycin lowers child deaths when all young children are treated, but not when only infants are

    The World Health Organization's 2020 guideline recommended giving mass azithromycin, which lowers child mortality in high-mortality settings of sub-Saharan Africa, only to infants, to limit antibiotic resistance; no trial had then tested that. Under a pre-registered plan we pooled every randomized trial by whom it treated. Treating all children under five lowered their mortality by 14.1% (CI 7.4% to 20.3%), consistently across trials. In the three trials that treated only infants, infant mortality was not detectably lower (rate ratio 0.971, CI 0.867 to 1.086), an interval that excludes the effect of treating all children. Infants had lower mortality when all children were treated, though a between-trial comparison of the two strategies fell short of significance, and giving azithromycin to individual infants at clinic visits showed no effect. The infant-only approach has not lowered mortality in any trial that tested it; treating all children under five has.

    • Published, Reproduced.Published, Reproduced: In 5 placebo-controlled comparisons from 3 cluster-randomized trials (MORDOR in Niger, Malawi and Tanzania; AVENIR in Niger; CHAT in Burkina Faso), twice-yearly mass azithromycin to every child 1 to 59 months old lowered mortality among children 1 to 59 months by 14.1% (rate ratio 0.859, 95% CI 0.797 to 0.926; Holm-corrected p = 0.015; I² = 0%), and the reduction held with a common-effect model (0.859, 0.813 to 0.908) and with any one comparison left out (largest p = 0.044).
    • Published, Reproduced.Published, Reproduced: In the 3 cluster-randomized trials that gave azithromycin twice a year to infants 1 to 11 months old only, the approach the World Health Organization recommended in 2020 (AVENIR's infant arm in Niger, LAKANA in Mali, MIRAMA in Burkina Faso), infant mortality was not detectably lower than with placebo (rate ratio 0.971, 95% CI 0.867 to 1.086; p = 0.370), an interval that rules out a reduction larger than 13.3% and so excludes the 14.1% reduction seen when all children 1 to 59 months were treated; the estimate stayed near 1 with LAKANA's four-times-yearly arm instead (0.948, 0.856 to 1.050), without MIRAMA (0.963, 0.656 to 1.413), and with the 2 individually randomized infant trials added (0.969, 0.881 to 1.066).
    • Published, Reproduced.Published, Reproduced: Infant mortality was lower when all children 1 to 59 months were treated (rate ratio 0.823, 95% CI 0.707 to 0.958; 3 comparisons) than when only infants were (0.971), but the pre-registered meta-regression comparing the two strategies across trials did not establish a difference (ratio of rate ratios 1.187, 95% CI 0.974 to 1.447; p = 0.074; Holm-corrected p = 0.148); AVENIR's within-trial contrast of its all-children arm against its infant arm, estimated after registration from the two arms' printed mortality rates, was 0.830 (0.717 to 0.959).

15. Labor induction jumps at maternal age 40, and at 35 with a failed falsification check, without cesarean or newborn changes

    Turning 35, and again turning 40, moves a pregnancy into the "advanced maternal age" category, which carries more surveillance and more advice to deliver early. Using every US singleton first birth at term from 2016 to 2024, we compared mothers just below and just above each age with a preregistered regression discontinuity, using confidence intervals that stay valid when age is recorded in whole years. Labor induction jumps by 1.19 percentage points at 35 (honest 95% CI 0.7 to 1.68). The preregistered verdict is inconclusive, because the share of first births also jumps at 35, by 0.4 points. At 40, induction jumps by 2.86 points (2.05 to 3.67), and that secondary test meets its confirm rule. Delivery at 39 weeks rises at both ages. Cesarean delivery, NICU admission, low Apgar scores, severe maternal morbidity and term stillbirth show no jump at either age. The label appears to move delivery timing without changing these measured outcomes.

    • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: Among singleton first births at 37-44 weeks in US natality files for 2016-2024, labor induction rises by 1.19 percentage points at maternal age 35 (honest 95% CI 0.70 to 1.68, bias bound 0.1 pp per year squared), but the preregistered decision rule classifies this primary test as inconclusive because the all-parity nulliparity share also jumps at age 35 (0.40 pp, Holm-adjusted p = 0.023).
    • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In the same population, labor induction rises by 2.86 percentage points at maternal age 40 (honest 95% CI 2.05 to 3.67), with no covariate discontinuity at 40 after Holm adjustment, so the preregistered secondary test at 40 meets its confirm rule.

16. Default mode timescales are not the longest and do not differ in mild-to-moderate depression: a registered resting-state test

    Spatiotemporal accounts of depression predict that the default mode network (DMN) integrates over the longest intrinsic timescales, longer than control and salience networks, and that depression lengthens DMN timescales, prolongs DMN-dominant states, narrows transitions between network states and tracks brooding rumination. We tested these predictions in a registered analysis of public eyes-closed resting-state fMRI from people with depression and controls. Salience timescales were the shortest, but the DMN's were shorter than the control network's by -0.0416 s (CI -0.07 to -0.0125), opposite to the predicted order. Depression did not change DMN timescales (AUC 0.4015, CI 0.2708 to 0.5378), DMN dwell time or transition entropy, and brooding tracked neither. These data do not support the tested predictions.

    • Published.Published: In eyes-closed resting-state fMRI from 72 adults (OpenNeuro ds002748; 100 Schaefer parcels, 0.01-0.1 Hz band-pass, TR 2.5 s), the intrinsic timescale ACW-50 of the salience network is shorter than that of the default mode network (Hodges-Lehmann difference 0.0391 s, 95% CI 0.0057 to 0.0731) and of the control network (0.0751 s, 0.0397 to 0.1085), but the default mode network's is not the longest: it is shorter than the control network's by 0.0416 s (95% CI 0.0125 to 0.07).
    • Published.Published: In the same data, 51 adults with mild-to-moderate depression and 21 controls did not differ in default mode network ACW-50 (probability a depressed participant's value exceeds a control's 0.4015, 95% CI 0.2708 to 0.5378), in mean dwell time of default-mode-dominant states (0.5131, 0.3679 to 0.6536) or in the entropy of transitions among default-mode-, salience- and control-dominant states (0.549, 0.3987 to 0.6975); the design had 80% power only for differences near an AUC of 0.70.
    • Published.Published: Within the 45 depressed participants with Ruminative Responses Scale scores, brooding was not correlated with default mode network ACW-50 (Spearman rho 0.1065, 95% CI -0.1848 to 0.3812) or with default-mode-dominant dwell time (rho -0.2063, -0.4732 to 0.0887).

17. Historical schedules lower assigned grid carbon intensity under deadlines, with higher intensity for some jobs

    Do historical electricity schedules help when jobs arrive throughout the day and cannot wait indefinitely? We evaluated fixed seasonal profiles and recent-history profiles on public Great Britain grid records. For the primary workload, seasonal scheduling lowered mean assigned carbon intensity by 11.24% in 2024 and 12.01% in 2025 relative to immediate execution. Yet 17.61% and 15.55% of jobs received higher intensity. Recent-minus-seasonal mean differences were -0.21 and -0.07 g CO2/kWh. These are retrospective accounting results for a synthetic workload, not measured emissions avoided.

    • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: Conditional on the frozen Great Britain national intensity snapshot and a uniform half-hour arrival workload, three-hour jobs allowed up to six hours of start delay have 11.24% and 12.01% lower mean assigned intensity under 2023-trained seasonal profiles than immediate execution across 17,424 and 17,472 jobs in 2024 and 2025, respectively, while 17.61% and 15.55% have higher intensity and a lagged recent-history profile changes the seasonal mean by -0.21 and -0.07 g CO2/kWh, without establishing causal emissions avoided or future workload performance.

18. Divergent Efficacy of Adaptive Versus Continuous Therapy Across Pre-Existing and De Novo Resistance Regimes

    Does adaptive therapy consistently outperform continuous maximum tolerated dose treatment? Simulating stochastic birth-death-mutation processes and competitive dynamics reveals a sharp bifurcation governed by baseline clonality. Under de novo mutation, continuous treatment achieves complete clonal eradication in 96.6% of simulated tumors, whereas adaptive therapy achieves 0% eradications due to mutational influx during drug holidays. Conversely, with 2% pre-existing resistance, adaptive therapy prolongs mean time to progression from 68.6 days to 74.8 days while reducing cumulative drug exposure by 18.1%. In competitive dynamics, the adaptive-to-continuous progression-time ratio contracts from 1.11 under a 20% fitness cost to 1.09 under neutral resistance. Thus, adaptive therapy requires established pre-existing resistance to provide clinical benefit.

    • Published, Reproduced.Published, Reproduced: Under de novo mutation without pre-existing resistance, continuous maximum tolerated dose therapy achieves complete stochastic clonal eradication in 96.6% of simulated tumors, whereas adaptive therapy achieves 0.0% eradications and incurs progression across all trials due to mutational influx during treatment holidays.

19. Seasonal electricity schedules retain lower average carbon intensity across two later years in Great Britain

    Can a simple electricity-use schedule transfer across years? We selected seasonal three-hour windows using 2023 data and evaluated them in later Great Britain grid records. Relative to midnight use, assigned average carbon intensity was 5.78% lower in 2024 and 13.15% lower in 2025. The schedule performed worse on 137 and 111 days, respectively. A single year-round window did not improve both years. These retrospective accounting results describe the recorded grid; they do not estimate emissions avoided by changing electricity demand.

    • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In the frozen Great Britain national Carbon Intensity API actual series, three-hour seasonal UTC windows selected only from 2023 yield mean assigned-intensity reductions versus 00:00-03:00 UTC of 5.778479% across 364 complete days in 2024 and 13.150070% across 365 days in 2025, compared with -9.430428% and 2.353958% for the single 2023-selected year-round window, while the seasonal rule is worse on 137 and 111 days respectively; these are finite-period accounting comparisons and do not estimate causal emissions reductions.

20. Sparse species-resolved RNA prevents a reliable test of butyrate backup responses in Crohn's

    Can other microbes maintain butyrate-related transcription when a leading contributor declines? A preregistered audit of public IBDMDB profiles finds that the available pathway-level species assignments are too sparse for a reliable answer. Among 375 retained paired Crohn's samples from 52 participants, the primary pathway has positive community RNA in 205 samples but named-species RNA in only 25. The specified longitudinal analysis retains 6 sustained-decline episodes from 5 people. Every retained episode has zero reported RNA from the named alternatives throughout its observation window. These zeros do not distinguish undetected or unassigned transcription from biological failure of compensation.
