Abstract: A system for controlling gene expression in yeast comprises a repressible gene expression plasmid that has a regulator binding sequence for camR and a target gene sequence. The system also includes a transcription enhancer expression plasmid; wherein said transcriptional activator protein binds to the regulator binding sequence in the absence of a transcriptional inhibitor. The system is used in a method for controlling expression of the target gene through the use of camphor. The target gene is expressed in the absence of camphor but unexpressed if camphor is added to a solution of cells containing the plasmids.

Abstract: A magnetoelectric memory cell with domain-wall-mediated switching is implemented using a split gate architecture. The split gate architecture allows a domain wall to be trapped within a magnetoelectric antiferromagnetic (MEAF) active layer. An extension of this architecture applies to multiple-gate linear arrays that can offer advantages in memory density, programmability, and logic functionality. Applying a small anisotropic in-plane shear strain to the MEAF can block domain wall precession to improve reliability and speed of switching.

Abstract: This disclosure provides novel hydrogels that can undergo multiple gel-sol transitions and methods of making and using such hydrogels, particularly in anastomosis procedures. The peptide hydrogels comprising a fibrillar network of peptides that are in an amphiphilic ?-hairpin conformation. The peptides comprise photo-caged glutamate residues with a neutral photocage that can be photolytically selectively uncaged to disrupt the fibrillar network and trigger an irreversible gel-sol phase transition of the hydrogel. Isolated peptides for making the disclosed hydrogels are provided, as are methods of using the peptide hydrogels in anastomosis procedures.

Abstract: A system and method for generating dynamic susceptibility contrast information from medical imaging data acquired using a magnetic resonance imaging (MRI) system and from a subject having received a dose of a contrast agent. A plurality of images are acquired of the subject. Using the images, an arrival time correction (ATC) is determined that includes a value for at least one of a time shift variable, a time stretch variable, and an amplitude scale variable. The ATC is applied to a model of dynamic susceptibility contrast that relates a measure of signal change over time with a correction term to dynamic susceptibility contrast information to create a corrected model of dynamic susceptibility contrast including the ATC. At least one contrast agent concentration curve is generated from the plurality of images using the corrected model.

Abstract: A novel method for simulating radiation dose reduction that enables previews of low-dose x-ray projection images, low-dose computed tomography images and/or cone-beam CT images. Given an existing projection or set of projections of the patient acquired at a nominal dose, the method provides a means to produce highly accurate preview images that accurately reflect the image quality associated with reduced radiation dose. The low-dose preview image accounts for characteristics of the imaging system, including blur, variations in detector gain and electronic noise, and does so in a manner that yields accurate depiction of the magnitude and correlation of image noise in the preview images. A calibration step may be included to establish the system-specific relationship between the mean and variance in detector signal, and incorporate an accurate model for system blur such that correlations in the resulting LDP images are accurate.
Abstract: Provided are modified microorganisms which are modified such that their growth can be controlled using exogenously provided compounds. The microorganisms can be modified by genetic alterations that include a promoter inducible by a first exogenously supplied compound. The promoter can be configured to drive expression of an RNA coding sequence that may be essential to growth of the microorganism. The microorganisms may also be modified to include site specific recombinase recognition sites flanking or within the RNA coding sequence so that expression of the corresponding site specific recombinase will disrupt transcription of the RNA. The site specific recombinase can be configured such that it expression and/or activity is suppressed by a second exogenously supplied compound. Methods of making the modified microorganisms and kits that contain reagents for making and using the modified microorganisms are also provided.
