Mechanisms and functional significance of nuclear compartmentalization
The mammalian cell nucleus is a complex yet highly organized structure. There is significant amount of knowledge about the organization of nucleus; however, the influence of such structural complexity of the nucleus in gene regulation is poorly understood. For better understanding of the effects of …

FlexC: Flexible Compartmentalization Through Automatic Policy Generation
… to prevent and mitigate these vulnerabilities is compartmentalization. Previous work has mostly focused on the enforcement of compartmentalization policies; to date little research has addressed the creation of such policies. Users are assumed to manually create and supply policies via annotation. …

Securing Operating Systems using Hardware-Enforced Compartmentalization
… and automatic LLVM instrumentation to enforce compartmentalization in an effective manner without requiring significant developer effort. Using Arm Pointer Authentication Codes (PAC) and Arm Memory Tagging Extensions (MTE), HAKC enforces a two-tier compartmentalization scheme that is performant …

Compartmentalization and axon guidance in the Drosophila brain
The Drosophila brain is composed of many morphologically and functionally distinct processing centers and brain morphogenesis depends on the creation and maintenance of distinct boundaries between adjacent regions to prevent cells from mixing. In the Drosophila visual system, I have found that Slit …

Compartmentalization of HIV-1 in the Secondary Lymphoid Tissues
… which there is a restriction of virus flow. Compartmentalization of HIV-1 creates numerous sites within the body in which the virus can undergo independent evolution, giving rise to a more diverse total viral population. Given the sessile nature of the FDC, I hypothesized that contrary to …

Genomic and microscopic dissection of nuclear compartmentalization and function
… results reveal an initial 3D picture of nuclear compartmentalization. Further extension of TSA-Seq mapping into multiple nuclear compartments in different cell types and states will help further dissect nuclear organization and function.

Making connections: Compartmentalization in pre -calculus students' understanding of functions
… through their experiences. Students demonstrate compartmentalization when they understand a construct or concept within one representation, but not another, or when they do not connect mathematically related ideas. For instance, a student may understand f(x) to mean plug x into the function …

Compartmentalization evaluated to explain discrepancies calculating cartilage fixed charge density
… did not include any collagen, there were no compartmentalization effects due to structural factors. A similar single-compartment was done using a non-ionic contrast agent to test for steric exclusion based compartmentalization. Although MR measurements revealed a discrepancy in contrast agent …

Compartmentalization in the northern segment of the Brazos River Alluvium aquifer.
Alluvial aquifers such as the Brazos River Alluvium aquifer in central Texas can contain locally significant amounts of groundwater that may be used for irrigation, domestic supply, or to mitigate stress applied to other groundwater and surface water resources. Alluvial aquifers occur within the …

Diagnostic Imaging of Foreign Bodies and Compartmentalization in the Canine Manus
Injury of the manus is an important cause of morbidity and function loss in dogs, especially working breeds. These injuries may cause foreign body retention and can lead to persistent infection. Accurate methods for diagnosis and localization of pathology in this anatomically complex region are …

Requirements for Compartmentalization of Penicillin-Binding Proteins during Sporulation in Bacillus subtilis
Penicillin-binding proteins (PBP's) are membrane-associated enzymes involved in the polymerization of peptidoglycan. PBP's are divided into three classes based upon their molecular weights and functional domains. Gene expression is regulated in the two differentiated cells in Bacillus subtilis, the …

Relationship Between Fault Zone Architecture and Groundwater Compartmentalization in the East Tintic Mining District, Utah
… groundwaters across the fault zone. The compartmentalization of groundwater shows that fault zone variability (from strain partitioning and multiple deformation episodes) make traditional basin flow concepts inaccurate and difficult to apply in this area.

Sedimentary basin evolution and structural compartmentalization in the northernmost Andes : Eastern Cordillera and Magdalena Valley, Colombia
Topographic development of the northernmost Andes is recorded in Mesozoic to Cenozoic clastic basin fill along the Middle Magdalena Valley (MMV) and Eastern Cordillera (EC) fold-thrust belt of Colombia. The Volador study area (5.5-6.0 °N) displays structures that pre-date and post-date an Eocene …

Male genital tract versus blood HIV-1 compartmentalization and selection: the first step of the transmission bottleneck?
… numerous prior studies have shown that there is compartmentalization of HIV-1 populations between the general circulation and the genital tract, raising the possibility that the genital tract is an important selective environment. Collectively, prior studies of genital tract compartmentalization …

Role of the Aspartyl Protease SpoIIGA in the Compartmentalization of Sigma Factor Activation During Sporulation of Bacillus subtilis
… in the mother cell. The current model for σE compartmentalization suggests that before septation SpoIIGA is evenly distributed throughout the entire cell membrane. Once septation occurs, there is a higher amount of SpoIIGA in the mother cell than in the prespore. SpoIIGA is then concentrated …

Seismic attribute-assisted structure analysis of the Mackay dome transpressional system, Bighorn basin, southern Montana: Evidence for reservoir compartmentalization
The Mackay dome field is found in southern Montana, in the northern most section of the Bighorn basin. It is characterized by a transpressional positive flower structure that lies above the left lateral Nye-Bowler lineament. The main reservoir is the Cretaceous Greybull sandstone, which is sourced …
