The 2008 federal intervention to stabilize Fannie Mae and Freddie Mac [PDF]
Fannie Mae and Freddie Mac are government-sponsored enterprises that play a central role in U.S. residential mortgage markets. In recent years, policymakers became increasingly concerned about the size and risk-taking incentives of these two institutions.

FEBS Open Bio, EarlyView.Ca2+‐mediated response to DMSO was investigated in Saccharomyces cerevisiae cells expressing Ca2+‐dependent aequorin. Cell exposure to DMSO induced a cytosolic Ca2+ wave dependent on the integrity of the Cch1/Mid1 channel. Deletion of KCS1 or VIP1 genes encoding the phosphoinositol pyrophosphate (PP‐IP) synthases suppressed the DMSO‐induced Ca2 ...

Estimating the effect of mortgage foreclosures on nearby property values: a critical review of the literature [PDF]
In response to the wave of residential mortgage foreclosures in the past few years, federal, state and local government intervention programs have aimed to reduce the presumed social costs of foreclosures.

Frame potentials and the geometry of frames [PDF]
arXiv, 2014 This paper concerns the geometric structure of optimizers for frame potentials. We consider finite, real or complex frames and rotation or unitarily invariant potentials, and mostly specialize to Parseval frames, meaning the frame potential to be optimized is a function on the manifold of Gram matrices belonging to finite Parseval frames.

FEBS Open Bio, EarlyView.The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

Regional Migration and House Price Appreciation [PDF]
Despite both empirical and anecdotal evidence suggesting the importance of common systematic factors determining price appreciation in residential real estate markets, the existing literature focuses almost exclusively on the impact of local variables ...

Asymptotic and Finite Frame Length Analysis of Frame Asynchronous Coded Slotted ALOHA
, 2016 We consider a frame-asynchronous coded slotted ALOHA (FA-CSA) system where users become active according to a Poisson random process. In contrast to standard frame-synchronous CSA (FS-CSA), users transmit a first replica of their message in the slot ...

TDAN: Temporally Deformable Alignment Network for Video Super-Resolution [PDF]
arXiv, 2018 Video super-resolution (VSR) aims to restore a photo-realistic high-resolution (HR) video frame from both its corresponding low-resolution (LR) frame (reference frame) and multiple neighboring frames (supporting frames). Due to varying motion of cameras or objects, the reference frame and each support frame are not aligned.

Gabor single-frame and multi-frame multipliers in any given dimension [PDF]
arXiv, 2020 Functional Gabor single-frame or multi-frame generator multipliers are the matrices of function entries that preserve Parseval Gabor single-frame or multi-frame generators. An interesting and natural question is how to characterize all such multipliers.

The role of circular RNAs in regulating cytokine signaling in cancer
FEBS Open Bio, EarlyView.Cytokines present in the tumor microenvironment fuel cancer development. Aberrant expression of circRNAs contributes to cancer progression. Cytokines are involved in regulating circRNA biogenesis. Furthermore, aberrantly expressed circRNAs regulate the expression of ligands, receptors, and downstream effectors involved in cytokine signaling to promote ...
