What changed

In these studies removal caused miscalibration by group without changing AUC, and mitigation on one measure could worsen another. The breast model is logistic regression, the dementia cohorts are from one mostly White county with possible label noise, and harms such as missed cancers were not measured directly.

What changed

Neither extreme holds in these studies: prompting got close on loose matching and beat older baselines on one structured task, but fine-tuned models kept the edge on exact extraction. Datasets were small or synthetic, commercial models change over time (run-to-run agreement 0.913), and real hospital notes were not tested for privacy reasons.

What changed

Slow flow matches rigidity percolation in an off-lattice simulation, but flow rate produces a line of exponents. The system is 2D, frictionless and athermal, percolation uses an arbitrary force threshold rather than a direct rigidity test, and β's error bars are too large for a conclusive test.

What changed

In these films the enhancement is large and monotonic, and BCS-like behaviour survives. The paper does not explain why; Tc was measured on only four films, the substrate's role was not isolated, and the odd-frequency pairing interpretation of vortex cores rests on model fits.

What changed

Their search paths do not match experimental folding behaviour. The caveat is important: these tools were never designed to simulate folding, AlphaFold 2 was tested with one trajectory per protein, and experimental ground truth on intermediates is itself fuzzy.

What changed

On small biomedical datasets, learned representations did not help and cross-validation overstated performance, with one study proposing at least 500 users before trusting results. The thresholds come from single datasets and simple rules of thumb, and much larger labelled datasets could change the picture.

What changed

No swimming or flow difference was found; the extra turning of the mutant traced to beating asymmetry, not hydrodynamics. Hair stiffness was not measured, the mutant also lacks a cell wall, and small waveform differences could hide in six-cell samples. The hairs' actual role is untested.

What changed

In this idealised protocol, efficiency stays at 1 regardless of error; noise only lowers information per measurement. It is theory and simulation, requires instantaneous fine control of trap stiffness and centre, and dissipation from imperfect tuning is only discussed qualitatively.

What changed

A careful energy-conserving model puts the non-thermal share at a tiny fraction under steady light, while a pulsed strong-coupling experiment reports measurable injection. The model is for silver without interband transitions, and the experiment is one material system whose efficiency mechanism is proposed rather than measured, so neither settles the other.

What changed

Purified silicon gave the longest dephasing time, but a natural-silicon device came close and demonstrated high single-qubit fidelity. Each result is from one device, neither shows a two-qubit gate, and the two use different qubit encodings, so they are not a like-for-like comparison.

What changed

Planning in that task barely changes reward, people planned more when a redesigned task made it pay, and the marker can be produced by non-planning agents. The human result is a correlation between task groups, most work here is simulation, and the authors argue the artefact is weak in the original task.

What changed

Task-trained deep networks predicted both V1 and IT better in these studies. They still leave nearly half of V1's explainable variance unexplained, only one supervised network was tested for IT so supervision is confounded with architecture and data, and the data come from small image sets and few animals.

What changed

On exam performance, the average cost was close to zero — though students chose their format rather than being randomised, and exams do not capture soft skills or later careers. The interesting question moves to why particular courses differed.

What changed

The short and ultrashort fraction dominates in these matrices. With 81 participants this cannot estimate national prevalence, and it establishes exposure rather than any health effect at these levels.

What changed

A middle condition shows the intervention underperforming when assessment is not aligned — which is the more useful finding. The cohorts ran in different years, so year and instructor effects are not excluded.

What changed

The collaboration signal is measurable within a course. Whether an instructor acting on it changes outcomes is untested here, and would need a controlled comparison.

What changed

The symptom inventory is far wider than the clinical literature had described, and post-exertional malaise moved to the centre of the picture. Prevalence, though, remains an open question this design cannot close.

What changed

Product use is now comparable to mobile sources nationally. This is an inventory, not a simulation of the resulting ozone or aerosol, and the largest uncertainty is in how much product is used and what is in it.

What changed

The evidence base was geographically narrow and politically convenient, which is traceable in where the research was done and how the diagnosis was used. This is not a new nutrition trial, some figures are cited from earlier surveys, and it does not measure malnutrition incidence today.

What changed

Both assumptions failed in this sample while other traits held. The outcome is self-reported rather than measured, the students are language majors at one Chinese university, and the semester was emergency remote teaching rather than designed online instruction.

What changed

Performance and motivation came apart in this course. Classes were assigned at class level rather than individually, the sample is 60 students in one Malaysian course, and no mechanism for the performance gain was identified.

What changed

Regional scaling with warming level is robust across generations, and at +1.5 °C the regional term dominates the uncertainty. The CMIP6 archive was still incomplete when this ran, and the analysis does not explain the regional differences it finds.

What changed

Their dependence is strong now and strengthens under warming across most of the global coastline. The analysis excludes large river catchments and mean sea-level rise, uses six CMIP5 models at roughly 100 km coastal spacing, and stops short of full inundation modelling.

What changed

Microbial biomass and turnover explain more of the pattern than root input does in this grassland. One sampling date at one site, and carbon-use efficiency was statistically flat rather than shown to be irrelevant everywhere.

What changed

The structure is hierarchical, which changes how evaluation data should be read. Importance ratings are self-reported and are not measured learning gains, and the sample skews young from courses whose instructors opted in.

What changed

The brain–symptom associations and the cluster structure both fail under appropriate validation. This shows the method cannot support the claim — not that biological subtypes of depression do not exist.

What changed

The mechanism was contested and contingent, and a state-licensing alternative was operating in parallel. The paper does not measure today's orphan drug prices or estimate how many of the 350-plus post-1983 approvals would have appeared without the Act.

What changed

Two developed alternatives exist and pull in opposite directions. Both are normative proposals rather than trials: neither has been shown to produce better-informed participants, and dynamic consent has not been shown to raise recruitment.

What changed

The relationship is disease-specific rather than a property of tau. The design is cross-sectional so it cannot show spread over time, the groups are small, and the PET ligand binds aggregated tau with known off-target signal.

What changed

Throughput rises by orders of magnitude and reagent consumption falls to sub-microgram. Qualitative reproducibility degrades at the fastest settings, and translating a DESI hit into an optimised preparative yield is not demonstrated here.

What changed

A developmental reading accounts for the same neural findings without a pathology premise, and reframes recovery accordingly. This is a theoretical essay: it measures no quit rates and cites recovery-without-treatment figures from the wider literature.

What changed

Bed and bathymetry are resolved together, and the retreat record matches the new topography. Resolution still falls to about 1 km where gaps are interpolated, and radar thickness uncertainty is roughly 50 m.

What changed

Thickness is the dominant component, and it replicates across four samples and three countries. MRI cannot show the cellular processes behind it, and the accelerated design combines age cohorts rather than following individuals from 7 to 29.

What changed

The regulatory architecture itself carried part of the delay, through a classification made before the outbreak began. The paper does not adjudicate every subsequent governance reform or quantify how many deaths the delay caused.

What changed

A third position holds people responsible without blaming them, and the paper reports it as the stance found in clinical practice. This is not a trial of therapeutic communities, cross-cultural stigma evidence is cited from others, and the stance may not transfer to criminal courts.

What changed

A surrogate reaches useful accuracy and ships with a domain-of-applicability test. The model covers octahedral first-row complexes with the trained ligand set, descriptors ignore three-dimensional interligand clashes, and cyclams and early metals are explicit outliers.

What changed

The feedback improves model skill in both seasons and produces opposite-signed ozone responses. Heterogeneous N₂O₅ chemistry is not quantified, two months of one year cannot represent all conditions, and urban monitors may not represent rural ozone.

What changed

A transcriptomic stratification replicates across cohorts and predicts mortality. It does not show that assigning patients to a signature and treating them differently improves survival — that requires a trial nobody has run here.

What changed

A large low-exposure cohort finds elevated risk throughout its range. Confidence intervals widen at the bottom of the spline, and smoking intensity and indoor sources are imperfectly captured.

What changed

The documentary practice is now described, and its consistent omissions identified. The analysis covers the forms themselves: it did not examine local-language translations or how forms are used in recruitment, and it cannot say whether participants understood what they signed.

What changed

An isolated-site catalyst delivers the selectivity that particle surfaces cannot. The structure was determined before and after reaction rather than during it, so the working state of the site remains an inference.

What changed

At least these three reactions propagate chains, and the community's standard control does not detect them. The authors are explicit that this does not make every photoredox reaction a chain process.

What changed

A meaningful amount is present at diagnosis and continues faster in those with cognitive impairment. The relationships are correlational, so thinning is not shown to cause cognitive decline, and 18 months is short relative to the disease course.

What changed

Separating traffic-specific from total particles changed the result within one cohort. This is observational incidence, exposure is modelled at the residence rather than measured personally, and a 331-case cohort limits precision.

What changed

The products are separate and structurally distinguishable, while a kinetic interaction persists at the nucleation step. Atomic structures of mixed oligomers are not solved, and disease relevance is inferred from peptide biophysics rather than from patients.

What changed

Multi-site sampling shows substantial spatial heterogeneity and a pre-existing resistant clone in this cohort. With 14 patients and significance only on a median split, this is a signal worth pursuing, not a clinical test.

What changed

The naming was unstable and moved with medical and institutional pressures. Without follow-up the records cannot show whether treatment lasted, officers are under-counted because they were treated elsewhere, and the files cannot settle organic versus psychical aetiology.

What changed

A 1 km surface resolves spatial structure across the region with good cross-validated skill. The maps are statistical predictions rather than speciated measurements, cloud-obscured retrievals leave gaps, and the study relates nothing to health outcomes.

What changed

Its two domains have very different validity, and only the activity domain tracks change. A 95-person Northern Ireland sample cannot establish performance in every country, and the change analysis with n = 41 was underpowered.

What changed

A multi-tissue clock works, which reframes methylation drift as a systemic phenomenon. It predicts age; it does not show that methylation causes aging, and its accuracy varies by tissue and disease state.

What changed

Two modalities agree within one sample. The participants are high-functioning children and adolescents, so this does not extend to adults or to lower-functioning individuals, and a cross-sectional design cannot say whether these differences precede or follow the behavioural phenotype.

What changed

Orbital mixing carries a large share of the binding energy, and the trend across halide acceptors can invert. These are gas-phase model trihalides, so the argument is about where the energy comes from, not a prediction for crystals or protein sites.

What changed

Two independent prospective cohorts show a graded association with years worked. The design cannot establish causation, and the mediating role of weight gain is unresolved.

What changed

A method with an internal validity check narrows the range considerably. It is still a model extrapolation, it does not cover prokaryotes — whose species concept differs — and it will move as synonymy and sampling improve.

What changed

A full screen gives the context a single-site result lacks, and identifies brain and cervical cancer as the leads worth pursuing. Confounder control shrank many smoking-related associations, cervical results lack HPV data, and the exposure is modelled at the residence.

What changed

Composition is an effect modifier, so mass alone under-describes the exposure. The study does not identify which species is responsible, and it covers only people aged 65 and over.

What changed

Compliance has not been shown to deliver protection, and the field lacks the outcome measures that would show it either way. This is a conceptual and policy argument rather than an audit of named committees, and it stops short of proposing a full metric.

What changed

The research effort and the policy refusal ran side by side, and the naming carried the explanation. This is a history of British medical and policy discourse; it is not a prevalence survey of vitamin D deficiency today, and some digitised colonial-era passages are fragmentary.

What changed

A risk-and-education frame took hold that still structures how health behaviour is addressed. This is a British institutional history: it does not measure how much smoking fell because of the report, and it is not a global account of tobacco epidemiology.

What changed

Epigenetic state at the locus, not the presence of the transcription factor, tracks whether the phenotype persists. The data are mostly from mouse, and human translation needs its own evidence.

What changed

A gene can be central to the physiology and absent from the heritability. This is mechanistic human physiology, not a trial: nothing here shows that lowering TXNIP improves glycaemic outcomes.

What changed

The consent justification is put under pressure by a comparison the sporting frame usually prevents. This is a critical appraisal from 2007: it is not a prevalence study of doping, and it does not set out an alternative code in detail.

What changed

Bursting is a property of the gene, and the intrinsic/extrinsic decomposition attributes most of the spread to the locus. The study does not map burst kinetics for every gene or in tissue, and it does not identify a single molecular switch.

What changed

Ligand class is a property of the ligand-receptor pair. This resolves the specific Wnt5a conflict; it does not map which receptors are actually present in any given tissue, which is what would be needed to predict the output in vivo.

What changed

Seed pairing became the organising rule for animal microRNA targeting. The rules are established for the microRNAs studied, and a predicted site is still not equally functional in every tissue.

What changed

Two papers in the PaperFren library disagree by age group. Neither is large enough to settle the question. The conservative reading is: costs are clearer in young adults here; older-adult resilience was observed in a highly screened sample on a short task.

What changed

This study replicates a sleep benefit for word pairs in children, then splits the memory: sleep helped item and source separately more clearly than the bound combination. The authors note temporal list context may be a weak episode cue, and subgroup ns were small.

What changed

This pair of experiments shows a reconsolidation-consistent pattern: reactivation plus a visuospatial task reduced subsequent intrusions of an already-consolidated analogue memory. The authors are explicit that a trauma film is not a life-threatening event and that other games were not tested.

What changed

A short-delay experiment shows valence can move with facial feedback during reactivation. The authors note a 24-hour reconsolidation delay was not used, so long-term restabilization is untested here.

What changed

This paper is a central piece of the contested bilingual-advantage debate: no advantage here, plus evidence that popular EF tasks do not measure the same thing. It does not rule out effects in children, older adults, or other sociolinguistic contexts.

What changed

This experiment ties improvement to strategy change. Retrospective interviews and a small adaptive cell mean we cannot treat the mechanism as settled, but it undercuts a simple 'capacity grew' story.

What changed

This study places mPFC activity on a path between anhedonia and function. Sample size is small and the design is cross-sectional, so it is a mechanistic hypothesis with imaging support, not a confirmed causal chain.

What changed

This paper shows a delayed divergence consistent with accelerated long-term forgetting, correlated with self-reported awakenings. It does not prove awakenings cause the forgetting.
