How do we compare writing with and without cards?

At the same writing position, the same model produces one first result with cards and one without. All 280 pairs enter the overall anonymized review, which assesses whether a decision not to continue fits the draft.

Overall: 138 with-card wins, 26 ties, 107 no-card wins, 5 pairs where neither was usable, and 4 inconclusive judgments. Both sides wrote text in 218 pairs; 48 had a deliberate stop and 14 included an invalid output.

HOW DOES BLIND JUDGING WORK?

① Anonymize both outputs
The AI judge sees the same draft and both first outputs without knowing which received cards.

② Compare and swap order
The judge applies task-specific criteria in X/Y and then Y/X order.

③ Review disagreements
A third pass resolves disagreements. Incomplete reviews remain in the denominator.

How are positions and cards selected?

We selected 40 writing positions in each of seven fields, for 280 comparisons. The position and relevant literature cards were set before each comparison, so both versions began from the same draft.

The main result retains every frozen position, including places where cards might not add a useful next move. This avoids selecting cases based on their outputs, but 49% describes the whole cohort, not a win rate where evidence clearly had an opportunity to help. This cohort did not record that opportunity label for each position before generation, so those two groups cannot yet be separated reliably.

CARD USE · 140/280

Reported card use in continuations with text

The model reports whether a card affected its continuation. In 140 of 280 tests it produced continuation text and reported card use. The previous count of 150 included 10 cases without continuation text and has been corrected.

COMPARISON · 70 / 7 / 30

Which written version was better?

Of the 107 reported-use cases where both versions produced text, the blinded AI judge preferred the with-card version 70 times, found 7 about the same, and preferred the without-card version 30 times.

How are the two table percentages calculated?

The percentages use different groups: 50% counts continuations with text reporting card use among all 280 tests; 65% covers the 107 such cases with text on both sides. The generating model reports card use, while an anonymized AI judge compares writing quality.

Card use is self-reported by the generator. The anonymized AI judge sees the draft and source snippets, so source-aware preference remains possible; there was no independent human review. The overall result describes these 280 frozen positions, not a win probability for any writing task.

Status of the K-EUSO Orbital Detector of Ultra-high Energy Cosmic Rays

5 Discussion and Conclusions

…ent to make an important step in revealing the nature and origin of UHECRs . With the expected rate of triggered events of around 65 per year for energies above 50 EeV (assuming the Pierre Auger Observatory spectrum) and the energy resolution varying from 15% to 25% for different zenith angles, K-EUSO will allow us to verify certain results of Auger and the Telescope Array concerning the energy spectrum of cosmic rays at respective energies. With a sufficiently long mission, K-EUSO will provide an opportunity to test the dependence of the energy spectrum on the declination reported by the TA.

…, the uncertainty on the average composition will be reduced by the statistics collected in each energy bin. Two energy bins could be envisaged: one around the threshold (i.e., 5 × 10 19 5\times 10^{19} eV) and the other at the highest energies (i.e., close to 10 20 10^{20} eV). Both would contain decent statistics and would be separated enough to account for effects related to the energy resolution [ 68 ] . Thus, the data will also provide some information about the mass composition of cosmic rays, which would allow for directly comparable measurements over the entire sky for the first time.

Read overall AI review rationale

A = with cards · B = without cards

The draft ends with a paragraph discussing how K-EUSO will provide information about mass composition of cosmic rays, with a forward-looking statement about 'directly comparable measurements over the entire sky for the first time.' This position clearly needs a continuation: the paragraph makes a substantive scientific claim about composition measurements, and the academic reader expects either elaboration, qualification, or transition to implications. Output A provides a precise, well-scoped continuation that introduces a critical caveat about propagation modeling and photodissociation effects—directly relevant to the composition topic just raised, appropriately hedged with 'nevertheless,' and grounded in established physics (consistent with the provided sources on GZK effects and photodissociation). It extends the argument without redundancy. Output B's abstention ('complete') is inappropriate here: the draft does not make a complete argumentative move. The composition claim is forward-looking and requires either further development or a qualifying nuance before the section can properly end. Stopping at 'for the first time' leaves the reader hanging on an important methodological limitation that standard academic writing would address.

Preferred by blind review

The interpretation of the K-EUSO composition measurements will nevertheless depend on the modeling of UHECR propagation, since photodissociation interactions with the ambient radiation fields modify the nuclear composition between the source and Earth.

Card 1 · Implications of the cosmic ray spectrum for the mass composition at the highest energies

The significant attenuation of the cosmic ray flux above ∼5 × 10 19 eV suggests that the observed high energy spectrum is shaped by the so-called GZK effect (GZK: Greisen–Zatsepin–Kuzmin). This interaction of ultra-high energy cosmic rays (UHECRs) with the ambient radiation fields also affects their…

The significant attenuation of the cosmic ray flux above ∼5 × 10 19 eV suggests that the observed high energy spectrum is shaped by the so-called GZK effect (GZK: Greisen–Zatsepin–Kuzmin). This interaction of ultra-high energy cosmic rays (UHECRs) with the ambient radiation fields also affects their composition. We review the effect of photodissociation interactions on different nuclear species and analyze the phenomenology of secondary-proton production as a function of energy. We show that, by itself, the UHECR spectrum does not constrain the composition of cosmic rays at their extragalactic sources. While the propagated composition (i.e., as observed at Earth) cannot contain significant amounts of intermediate mass nuclei (say between He and Si), whatever the source composition, and while it is vastly proton dominated when protons are able to reach energies above 10 20 eV at the source, we show that the propagated composition can be dominated by Fe and sub-Fe nuclei at the highest e …

Card 2 · Measurement of the Cosmic‐Ray Energy Spectrum and Composition from 1017to 1018.3eV Using a Hybrid Technique

We study the spectrum and average mass composition of cosmic rays with primary energies between 10 17 and 10 18 eV using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the Michigan Muon Array (MIA).

We study the spectrum and average mass composition of cosmic rays with primary energies between 10 17 and 10 18 eV using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the Michigan Muon Array (MIA). Measurements have been made of the change in the depth of shower maximum as a function of energy. A complete Monte Carlo simulation of the detector response and comparisons with shower simulations leads to the conclusion that the cosmic-ray intensity is changing from a heavier to a lighter composition in this energy range. The spectrum is consistent with earlier Fly's Eye measurements and supports the previously found steepening near 4 × 10 17 eV.

Card 3 · Evidence for Changing of Cosmic Ray Composition between 1017 and 1018 eV from Multicomponent Measurements

The average mass composition of cosmic rays with primary energies between 10(17) and 10(18) eV has been studied using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the MIA muon array.

The average mass composition of cosmic rays with primary energies between 10(17) and 10(18) eV has been studied using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the MIA muon array. Measurements have been made of the change in the depth of shower maximum and the muon density as a function of energy. The results show that the composition is changing from a heavy to lighter mix as the energy increases.

Card 4 · Ultra high energy cosmic rays: the highest energy frontier

Ultra-high energy cosmic rays (UHECRs) are the highest energy messengers of the present universe, with energies up to 10 20 eV. Studies of astrophysical particles (nuclei, electrons, neutrinos and photons) at their highest observed energies have implications for fundamental physics as well as astrop…

Ultra-high energy cosmic rays (UHECRs) are the highest energy messengers of the present universe, with energies up to 10 20 eV. Studies of astrophysical particles (nuclei, electrons, neutrinos and photons) at their highest observed energies have implications for fundamental physics as well as astrophysics. The primary particles interact in the atmosphere and generate extensive air showers. Analysis of those showers enables one not only to estimate the energy, direction and most probable mass of the primary cosmic particles, but also to obtain information about the properties of their hadronic interactions at an energy more than one order of magnitude above that accessible with the current highest energy human-made accelerator. In this contribution we will review the state-of-the-art in UHECRs detection. We will present the leading experiments Pierre Auger Observatory and Telescope Array and discuss the cosmic ray energy spectrum, searches for directional anisotropy, studies of mass com …

Card 5 · Energy spectrum and mass composition of primary cosmic radiation in the region above the knee from the GAMMA experiment

The energy spectrum of the primary cosmic radiation in the energy range 1 - 100 PeV and the extensive air shower (EAS) characteristics obtained on the basis of the expanded data bank of the GAMMA experiment (Mt. Aragats, Armenia) are presented. With increased statistics we confirm our previous resul…

Read full passage excerpt

The energy spectrum of the primary cosmic radiation in the energy range 1 - 100 PeV and the extensive air shower (EAS) characteristics obtained on the basis of the expanded data bank of the GAMMA experiment (Mt. Aragats, Armenia) are presented. With increased statistics we confirm our previous results on the energy spectrum. The spectral index above the knee is about -3.1, but at energies beyond 20 PeV a flattening of the spectrum is observed. The existence of the 'bump' at about 70 PeV is confirmed with a significance of more than 4σ. In the energy range of 10 - 100 PeV the shower age becomes energy independent and we observe a direct proportionality of the EAS size to the primary energy. This suggests an approximately constant depth of the EAS maximum in this energy range. This is evidence in favour of an increasing average mass of primary particles at energies above 20 PeV. The additional source scenario, which is a possible explanation of the 'bump' in the spectrum, also leads to t …

Earlier card-use comparison

The earlier diagnostic compared only cases with reported card use and text on both sides; its scope differs from the overall AI review above.

The with-card arm produced text and reported card use, but the no-card arm produced no text. This counts as reported use, without entering the two-text preference comparison.
