The ubiquitin-fold modifier 1 (Ufm1) is a posttranslational modifier that belongs to the ubiquitin-like protein (UBL) family. Ufm1 is present in nearly all eukaryotic organisms, with the exception of fungi. It resembles ubiquitin in its ability to be ligated to other proteins, as well as in the mechanism of ligation. While the Ufm1 cascade has been implicated in endoplasmic reticulum functions ...
UNLABELLED We demonstrated an unambiguous quantum dot cascade laser based on InGaAs/GaAs/InAs/InAlAs heterostructure by making use of self-assembled quantum dots in the Stranski-Krastanow growth mode and two-step strain compensation active region design. The prototype generates stimulated emission at λ ~ 6.15 μm and a broad electroluminescence band with full width at half maximum over 3 μm. The...
We present a hierarchical approach for information sharing among different classification tasks, in multitask and multi-class settings. We propose a top-down iterative method, which begins by posing an optimization problem with an incentive for large scale sharing among all classes. This incentive to share is gradually decreased, until there is no sharing and all tasks are considered separately...
During the creation of this paper, we interviewed industry participants and gathered research information from available publications and corporate websites. We thank for their input and guidance.
! z . In this paper we study cascades on finite networks in this upper boundary region via simulations. We distinguish two kinds of cascades: total network cascades (or TNCs) that essentially consume the entire finite network, and cascades corresponding to those predicted by percolation theory that consume only the initially struck vulnerable clusters and possibly a few others. We show that the...
The circulation around any closed loop is a Lagrangian invariant for classical, smooth solutions of the incompressible Euler equations in any number of space dimensions. However, singular solutions relevant to turbulent flows need not preserve the classical integrals of motion. Here we generalize the Kelvin theorem on conservation of circulations to distributional solutions of Euler and give ne...
In a wireless communication network, it is possible to locate a user and track its trajectory based on its transmission, during communication with access points. This type of tracking leads to the breach of a user’s location privacy. Prior solutions to this problem enhances user’s location privacy at the expense of communication Quality of Service(QoS) degradation. In this paper, we propose sil...

In this paper, we introduce cascade normal forms for underactuated mechanical systems that are convenient for control design. These normal forms include three classes of cascade systems, namely, nonlinear systems in strict feedback form, feedforward form, and nontriangular quadratic form (to be defined). In each case, the transformation to cascade systems is provided in closed-form. We apply ou...
