Closed form bound-state perturbation theory
(1980)
The perturbed Schrödinger eigenvalue problem for bound states is cast into integral form using Green's Functions. A systematic algorithm is developed and applied to the resulting equation giving rise to approximate solutions ...
Cohomology classes associated to anomalies
(1993-12)
One of the proposed settings for the description of anomalies in the setting of gauge field theories is a local bicomplex associated to a principal fiber bundle $ G \to P \to M$. It is a bigraded algebra with two differentials ...
Combined effects of aberrant MEK1 activity and BCL2 overexpression on relieving the cytokine dependency of human and murine hematopoietic cells
(2000-06-06)
The MEK1 oncoprotein plays a critical role in Ras/Raf/ MEK/MAPK-mediated transmission of mitogenic signals from cell surface receptors to the nucleus. In order to examine this pathway's role in leukemic transformation, a ...
Combined effect of free and forced convection on MHD flow in a rotating porous channel
(1982)
This paper gives a steady linear theory of the combined effect of the free and forced convection in rotating hydromagnetic viscous fluid flows in a porous channel under the action of a uniform magnetic field. The flow is ...
The M2a macrophage phenotype accompanies pulmonary granuloma resolution in Mmp12 knock-out mice instilled with multiwall carbon nanotubes
(MDPI, 2021-10-13)
Sarcoidosis is a chronic disease with unknown etiology and pathophysiology, characterized by granuloma formation. Matrix Metalloproteinase-12 (MMP12) is an elastase implicated in active granulomatous sarcoidosis. Previously, ...
Synaptic Hyaluronan Synthesis and CD44-Mediated Signaling Coordinate Neural Circuit Development
(MDPI, 2021-09-28)
The hyaluronan-based extracellular matrix is expressed throughout nervous system development and is well-known for the formation of perineuronal nets around inhibitory interneurons. Since perineuronal nets form postnatally, ...
Bivalve facilitation mediates seagrass recovery from physical disturbance in a temperate estuary
(Wiley, 2021-11-08)
Rapid global degradation of coastal habitats can be attributed to anthropogenic activities associated with coastal development, aquaculture, and recreational surface water use. Restoration of degraded habitats has proven ...
Storm surge and ponding explain mangrove dieback in southwest Florida following Hurricane Irma
(Springer Nature, 2021-06-28)
Mangroves buffer inland ecosystems from hurricane winds and storm surge. However, their ability to withstand harsh cyclone conditions depends on plant resilience traits and geomorphology. Using airborne lidar and satellite ...
Genome-Wide Identification of ARF Transcription Factor Gene Family and Their Expression Analysis in Sweet Potato
(MDPI, 2021-08-30)
Auxin response factors (ARFs) are a family of transcription factors that play an important role of auxin regulation through their binding with auxin response elements. ARF genes are represented by a large multigene family ...
Oral health, diabetes, and inflammation: Effects of oral hygiene behavior
(Elsevier, 2021-11-29)
The aim of this research was to assess the association between inflammation and oral health and diabetes, as well as the mediating role of oral hygiene practice in this association. Data were from the 2009–2010 National ...
