In this issue of CJASN, D’Agati and colleagues assess the association of the Columbia classification system of FSGS histologic variants with clinical characteristics and outcomes in patients enrolled in the FSGS Clinical Trial (FSGS-CT) (1). FSGS is the most common primary glomerular histology that results in ESRD (2). This is not a single disease, and it can have idiopathic, genetic, or second...

We study the formation and evolution of several molecules in a collapsing interstellar cloud using a reasonably large reaction network containing more then four hundred atomic and molecular species. We employ a time dependent, spherically symmetric, hydrodynamics code to follow the hydrodynamic and chemical evolution of the collapsing cloud. The flow is assumed to be self-gravitating. We use tw...

I study the quantum mechanics of a spin interacting with an “apparatus”. Although the evolution of the whole system is unitary, the spin evolution is not. The system is chosen so that the spin exhibits loss of quantum coherence, or “wavefunction collapse”, of the sort usually associated with a quantum measurement. The system is analyzed from the point of view of the spin density matrix (or “Sch...

Galloway-Mowat syndrome (GMS) is an autosomal recessive disorder with a poor prognosis that was first defined as a triad of central nervous system involvement, hiatal hernia, and nephrotic syndrome. However, this syndrome is now known to have a heterogeneous clinical presentation. The nephrotic syndrome is steroid resistant and is responsible for the outcome. The combination of collapsing glome...

We describe a modification to the collapsing method, a technique that aims to find the simplest structures in a cloud of microearthquakes by utilizing the statistical uncertainties in the data. In the modified collapsing method, the movements of the locations are dependent on the shape of the distribution of the locations within the confidence ellipsoid, and not just the position of the center ...

A very simple minisuperspace describing the Oppenheimer-Snyder collapsing star is found. The semiclassical wave function of that model turn out to describe a bound state. For fixed initial radius of the collapsing star, the corresponding Bohr-Sommerfeld quantization condition implies mass quantization. An extension of this model, and some consequences, are considered. This work is supported by ...

We investigate a tethered (i.e., fixed connectivity) surface model on spherical surfaces with many holes by using the canonical Monte Carlo simulations. Our result in this paper reveals that the model has only a collapsing transition at finite bending rigidity, where no surface fluctuation transition can be seen. The first-order collapsing transition separates the smooth phase from the collapse...
