|February 12, 2026
Resumen
Los modelos secuencia-a-ómicos (S2O) mejoran significativamente la reproducibilidad del mapeo genético fino al reducir las tasas de fallo de replicación. La integración de estas herramientas de aprendizaje profundo mejora la priorización de variantes en grandes conjuntos de datos genéticos.
Área de la Ciencia:
- Genómica
- Aprendizaje Profundo
- Bioinformática
Sus antecedentes:
- El aprendizaje profundo ha permitido a los modelos secuencia-a-ómicos (S2O) predecir fenotipos moleculares directamente del ADN.
- El mapeo genético fino tiene como objetivo identificar variantes causales, pero a menudo sufre problemas de reproducibilidad.
Objetivo del estudio:
- Evaluar sistemáticamente los modelos S2O para mejorar la reproducibilidad del mapeo genético fino.
- Desarrollar un marco para el mapeo fino informado funcionalmente utilizando predicciones S2O.
Principales métodos:
- Se evaluaron modelos S2O (AlphaGenome, Borzoi, Enformer, Sei) en conjuntos de datos eQTL de GTEx, TOPMed y MAGE.
- Se comparó el mapeo genético fino puramente estadístico con métodos que integran predicciones S2O.
- Se desarrolló un marco generalizado que genera PIPs informados funcionalmente (fiPIPs).
Principales resultados:
- El mapeo fino puramente estadístico mostró altas tasas de fallo de replicación (RFR).
- La integración de las predicciones del modelo S2O redujo sustancialmente las RFR.
- El marco fiPIP mejoró la priorización de SNP y la replicación de variantes en consorcios.
Conclusiones:
- Los modelos S2O, especialmente AlphaGenome y Borzoi, permiten la identificación robusta de variantes genéticas replicadas.
- El mapeo genético fino informado funcionalmente utilizando modelos S2O mejora la precisión y escalabilidad del mapeo genético.
- Los modelos S2O muestran una gran promesa para el descubrimiento genético reproducible y funcionalmente consciente.

Fineness of Cement
533
The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.

Fineness Modulus
1.5K
The fineness modulus (FM) of aggregate is a numerical index that measures the coarseness or fineness of the particles. It is calculated by adding the cumulative percentages of aggregate retained on each of a specified series of sieves and dividing the sum by 100.
Consider performing sieve analysis on sand through a set of ASTM sieves. The weight of aggregate retained in each sieve and pan placed at the bottom is recorded, as given in Column B of Table 1.

Per-Unit Sequence Models
462
An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

Types of Genetic Transfer Between Organisms
31.1K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.
