Spatial fluctuations of the pairing potential in disordered superconductors

We study the effect of site diagonal, non-magnetic, disorder on the a pairing amplitude in an extended Hubbard model with the intersite attraction. Analyzing fluctuations of a pairing potential we discuss the instability of mixed solutions, 's+d' and 's+id', in presence of disorder. The influence of disorder on extended s- and d-wave superconductors appear to be comparable but in certain regions of the phase diagram, even weak disorder can change the symmetry of the order parameter.Comment: 14 pages, 7 figures, Physica C (accepted

Motorized Garden Scooter

This project is a motorized garden scooter that has the capability of variable speed and power steering. It utilizes an already manufactured garden scooter base, DC motor, two regenerative motor drivers, a linear actuator, an Arduino Uno board, and a thumb stick. One of the motor drivers will be connected to the motor and will control the speed while the other will be connected to the linear actuator and will control the power steering. All these components will be connected to the Arduino Uno board which will then be connected to a battery. Challenges facing this project are creating a working code that will offer variable speed and power steering, mounting the components neatly and avoiding overloading the scooter. Over the course of this semester, the goal is to get a working motorized garden scooter that is functional and a code that can test its functionality. The result from this design would be a working solution for people who cannot garden due to mobility issues

Recombinant expression and antigenic properties of a 31.5-kDa keratinolytic subtilisin-like serine protease from Microsporum canis

A secreted 31.5-kDa keratinolytic subtilase (SUB3; AJ431180) is thought to be a Microsporum canis virulence factor and represents a candidate for vaccination trials. In this study, the recombinant keratinase (r-SUB3) was produced by the Pichia pastoris expression system and purified to homogeneity. Recombinant SUB3 displayed identical biochemical properties with the native protease. Experimentally cutaneously infected guinea pigs showed specific lymphoproliferative response towards r-SUB3, while no specific humoral immune response was induced except for one animal. The heterologous expression of SUB3 provides a valuable tool for addressing further investigations on the role of this keratinase in the specific cellular immune response and on its use in vaccination trials in the cat.
