Fair Isaac shares price the pressure from a cheaper credit score
After the VantageScore opening, Fair Isaac shareholders face a pricing question: how do banks use their new choice? Lower fees to retain customers and lost queries can both squeeze revenue.
Fermat's margin now fills 13 million lines
Anthropic says its agents needed 11 days to turn the Wiles and Taylor proof into 13 million lines of Lean a computer can check. A set of go-first dice took a loose group of mathematicians 15 years, and the program that cracked it ran on patterns those people had already found. Checking scaled; the finding still started from human structure.
In FePS3, the difference between two oscillations reveals a physical coupling
A spin wave and a lattice vibration in FePS3 respond together at their sum and difference frequencies. Newly accessible measurement data carry the signature of that coupling; the model selecting the dominant interaction currently explains the spectrum qualitatively.
Mladic's state honours expose Serbia's unfinished reckoning
Serbia began EU talks before Mladic's conviction. His return under the national flag shows how an international judgment and official remembrance can travel in different directions, with victims left between them.
Seattle Times puts the price of newsroom labor in the destruction of a model
The harm the two newspapers describe is less a copying harm than a substitution harm, which is why the sharpest demand in the complaint reaches past money to the training data and the model.
Section 232 protects the Louisiana mill and taxes the equipment that builds it
Seoul has asked Washington to ease Section 232 duties on the equipment for a 5.8 billion dollar mill in Louisiana. The same measure that rewards building inside the tariff wall also taxes what the building requires, and the bill lands on the venture's capital spending.
The grains in the simulation are centimetres wide; the answer given for Bennu sits below a millimetre
The tensile-strength curve for asteroid regolith was measured in simulations with mean grain diameters between 2.5 and 4.5 centimetres. The number quoted for Bennu's surface belongs to grains of a millimetre and below. An analytic scaling law bridges the two ranges, with no further simulations in between. The lower bound on grain size, 31.0 micrometres, is derived by requiring the model to agree with strength estimates that already existed.
The limit was 500 million dollars, and the network never touched it
Little in the fight between Glencore and Radiant World is documented: a 480 million dollar provision, three investigations and an asset freeze. The rest is assertion. Even the assertion leaves an uncomfortable question about what a single-company limit measures.
The overvaluation is measured against a wage that also has to buy the heating oil
The ESRI put Irish house prices 17% above what incomes, interest rates and demographics support, and traced the cause to affordability. The same household income is now paying €534.64 more to fill a heating oil tank, while the revenue set against both is a corporation tax Micheál Martin describes as possibly windfall.
The private-equity exit is blocked; the debt remains inside the company
Private-equity funds are holding more than 13,500 unsold companies. The risk is not the backlog by itself: debt stays with the operating company while a delayed sale narrows its room to refinance, invest or absorb a shock.
