bioRxiv : the preprint server for biology
|February 12, 2026
Resumen
HistoSweep es un nuevo marco para limpiar imágenes de histología de alta resolución. Elimina artefactos y ruido de fondo, mejorando la precisión en los análisis de patología digital y ómicas espaciales.
Área de la Ciencia:
- Patología digital
- Ómicas espaciales
- Biología computacional
Sus antecedentes:
- Las imágenes de histología de alta resolución son cruciales para la patología y la ómica espacial.
- Las imágenes de cortes completos (WSI) a menudo contienen artefactos y ruido de fondo que dificultan el análisis.
- Las herramientas actuales de control de calidad (QC) ofrecen una separación limitada de grano fino entre el tejido y las regiones no tisulares.
Objetivo del estudio:
- Presentar HistoSweep, un marco escalable para generar máscaras de tejido conscientes de la morfología a resolución celular.
- Abordar las limitaciones de las herramientas existentes en el control de calidad de grano fino para WSI.
- Mejorar la fiabilidad y reproducibilidad de los datos de patología digital y ómicas espaciales.
Principales métodos:
- HistoSweep integra filtrado de densidad, descriptores de textura y umbralización adaptativa.
- El marco genera máscaras de tejido a resolución celular, distinguiendo el tejido informativo de las regiones no informativas.
- Está diseñado para la escalabilidad, procesando WSI grandes de manera eficiente en CPU estándar sin requerir aceleración de GPU.
Principales resultados:
- HistoSweep elimina sistemáticamente las regiones no informativas preservando las microestructuras biológicamente relevantes.
- El marco demostró un rendimiento superior en 25 WSI diversas en comparación con los métodos existentes.
- Mejoró la visualización de imágenes, la precisión de la segmentación, la predicción de tipos celulares virtuales y la integridad de los datos de transcriptómica espacial.
Conclusiones:
- HistoSweep proporciona un paso de preprocesamiento fundamental para la patología digital y la ómica espacial.
- Permite un control de calidad escalable y de grano fino, crucial para una interpretación biológica precisa.
- La herramienta mejora la fiabilidad y reproducibilidad de los análisis computacionales que utilizan imágenes de histología.

Quality Control
2.9K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Quality Assurance
2.5K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality of Water
576
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Pulse amplitude and quality
3.2K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Testing Water Quality
395
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
