An Investigation of Portland Cement Concrete Utilizing 70% Class V Aggregate and 30% Calcareous Coarse Aggregate, R-255, 1973 [PDF]
, 1973 The main sources of coarse aggregate for secondary slip form paving in Southwest Iowa exhibit undesirable "D" cracking. "D" cracking is a discoloration of the concrete caused by fine, hairline cracks.

Tumor mutational burden as a determinant of metastatic dissemination patterns
Molecular Oncology, EarlyView.This study performed a comprehensive analysis of genomic data to elucidate whether metastasis in certain organs share genetic characteristics regardless of cancer type. No robust mutational patterns were identified across different metastatic locations and cancer types.

Recover Fine-Grained Spatial Data from Coarse Aggregation
, 2017 In this paper, we study a new type of spatial sparse recovery problem, that is to infer the fine-grained spatial distribution of certain density data in a region only based on the aggregate observations recorded for each of its subregions.

Multi-criteria aggregation for sensistive parcel-based census data [PDF]
, 2014 Modern urban planning considers various socio-economic issues and hence requires fine-grained, potentially sensitive spatial data, raising the disclosure dilemma: Whilst it is imperative to aggregate fine-grained sensitive records large enough to avoid ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma
Molecular Oncology, EarlyView.Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Compressive Strength of Concrete made from Natural Fine Aggregate Sources in Minna, Nigeria
Arid Zone Journal of Engineering, Technology and Environment, 2017 This work presented an investigation of concrete developed from five fine aggregate sources in Minna, Niger state, Nigeria. Tests conducted on the fine aggregate samples included specific gravity, sieve analysis, bulk density and moisture content.

Replacement of Sand with Bauxite Mining Waste in Concrete Production [PDF]
, 2019 The use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource. Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity ...

Molecular Oncology, EarlyView.Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Modification of soil structure of sand tailings: 2. effect of silt, sand and clay contents on aggregate development using organic amendments [PDF]
, 1996 The effect of skeletal materials (silt and very fine sand) and clay on aggregate formation and stabilization of organically amended sand tailings (99% sand) was investigated.
