CMOS-Compatible Doped-Multilayer-Graphene (DMG) Interconnects

Researchers at the University of California, Santa Barbara have developed a method to implement high-conductivity nanometer-scale doped-multilayer-graphene (DMG) interconnects that are compatible with high-volume manufacturing of integrated circuits (ICs). This method can also be applied to the implementation of any multi-layer graphene (MLG) or DMG based structures on any substrate or strata, and it overcomes all previous obstacles preventing it from being a Copper replacement. This innovation presents higher electrical conductivity than Copper, faster speed and lower noise for signal propagation and clock distribution in chips, and significantly lower resistive losses in on-chip power distribution. Compared to all currently available options, the DMG interconnect is shown to be the most reliable interconnect material because it produces negligible electromigration and less than 4% conductivity degradation over 1000 hours at room temperature without any encapsulation or barrier layer needed for Copper. It also has a substantially higher current-carrying capacity, allowing for improved speed through thinner wires, reduced noise-coupling, and lower switching energy or power consumption in integrated circuits. Overall, this helps create faster, smaller, lighter, more flexible, more reliable, and more cost-effective integrated circuits. 

DeepSEA and Seqweaver: Deep learning frameworks for the identification of de novo disease-causing mutations in noncoding sequences

DeepSEA and Seqweaver: Deep learning frameworks for the identification of de novo disease-causing mutations in noncoding sequences

 

Princeton Docket #s 18-3426, 18-3440

 

Researchers at Princeton University and Rockefeller University have collaborated to establish methods for the identification of de novo mutations in the vast noncoding genomic sequences. These methods, DeepSEA 2.0 and Seqweaver, use a novel deep learning framework to compare large datasets of regulatory sequences compiled from in vivo analyses with datasets of families affected by complex human diseases to pinpoint contributing mutations at the single nucleotide level in transcriptional regulatory sequences and RNA regulatory sequences, respectively. Application of DeepSEA 2.0 and Seqweaver to a database of families affected by simplex Autism Spectrum Disorder (ASD) revealed point mutations in transcriptional regulatory sequences and RNA regulatory sequences that contribute to an estimated 14% and 12% of cases, respectively. This provides more than a 50% increase to cases with the previously identified mutations in coding regions, which contribute to an estimated 30% of cases. DeepSEA 2.0 and Seqweaver can be used to analyze other complex human diseases with large datasets to identify contributing point mutations in noncoding regions.

 

The human genome is comprised of gene coding regions, which code for the amino acid sequences of proteins, and noncoding regions, which include sequences that regulate gene expression and RNA processing at the DNA and RNA levels.  While significant progress has been made in identifying disease-causing mutations in gene coding regions, the impact of noncoding mutations, which make up the majority of the human genome, remains underappreciated. The lack of progress in this area reflects the difficulty in distinguishing rare disease-relevant mutations from biological and technical variations that are common in noncoding sequences.

Isotope Tagging For Workpiece Authentication

 

Executive Summary

 

Over the last 50 years, the U.S. Department of Justice has ranked art crime behind only drugs and arms in terms of highest-grossing criminal trades. While many incidents go unreported making it difficult to estimate the volume and total economic value lost, Interpol estimates have put the losses worldwide due to forgery and theft at $4 to 6 billion. Various methods have been implemented to authenticate forgeries such as carbon dating for antiquities, stable isotope signatures in marble pieces, and UV/infrared analysis of paintings.  However, these techniques utilize a passive approach to analyze pre-existing conditions of pieces of art and more advanced methods are beneficial for tracking and authenticating valuable items. MSU researchers have developed a method of authentication using uncommon ingredients offering protection against sophisticated forgers and thieves.

 

Description of Technology

 

This MSU technology is a method of labeling (tagging) a workpiece with a rare man made isotope, which acts as a unique identifier for anti-counterfeiting purposes. The workpiece would be marked with sub-surface deposition directly into the backside of a canvas or other medium. These rare isotopes can be generated and implanted at advanced accelerator labs such as a cyclotron along with a visual marker and are impossible to generate otherwise. The unique decay signatures can be verified with inexpensive standard detection techniques offering an easy and reliable way to monitor the workpiece. The method may include unique combinations of isotope patterns and/or combinations of isotopes with distinct decay emissions and half-lives.

 

Key Benefits

  • Increased uniqueness (i.e. security) with use of rare, hard-to-obtain isotopes
  • Nonhazardous to people and workpiece
  • Non-destructive authentication

 

Applications

  • Isotopic anti-counterfeit labeling for high-end valuables
  • Civil and military tracking of dangerous material (e.g. explosives)

Indoor Navigation System for Mobile Devices

Airport travelers, retail shoppers and hospital visitors are a few of the millions of people who could benefit from improved indoor positioning. Yet even after decades of research, a simple and robust positioning system is lacking. Problems include high deployment overhead and inaccuracy.

One promising strategy exploits the unique frequency signatures of light fixtures, which are the result of manufacturing variations. A common cell phone camera may be used to detect these unique signatures and compare them with a database to determine one’s location. However, cameras have significant drawbacks such as limited bandwidth and low dynamic range, making it difficult to measure the signatures of individual light sources on a high ceiling, for example, in a warehouse store.\r\n\r\nUW–Madison researchers have developed an indoor navigation system using a mobile device equipped with two photodetectors. The system is able to determine the angular position of different light fixtures while avoiding the limitations in bandwidth and sensitivity associated with standard camera detectors. It is suitable for facilities with high ceilings more than three or four meters above the floor

Specifically, the new method can be illustrated in three steps: (i) identify multiple light source signals within the field-of-view according to known light source signatures; (ii) determine the angles of the multiple light sources; and (iii) identify the location of the mobile device based on the angle of the multiple light sources and a known mapping of light sources to locations.

Residency Interview Tracker

Title: Residency Interview Tracker

 

Invention:

The residency interview tracker (RIT) allows fourth year medical students and their advisors to track the residency application season real-time. The goal of creating the RIT was to lessen the financial, time and emotional burden the application and interview process requires . This is achieved on a student by student basis by allowing the advisers to know real-time how the students are faring during interview season and allow the advisors to intervene if necessary. This software will make the interview process for all medical school students and student affair advisers easier, more manageable and cost effective. Additionally, over-time data analytics on the student interview process as well as where students end up matching can be collected and analyzed.

 

Background:

Currently, advisors track student interviews through e-mailing and asking them where they are going and ultimately where they end up matching. This process is ineffective and requires a large amount of time.

 

Applications:

•       Medical students

•       Office of Student Affairs

•       Clinical faculty

•       Graduate education programs

 

Advantages:

•       Increased efficiency

•       More manageable

•       Cost effective

•       Reduced uncertainty

Independent tuning of workfunction and field enhancement factor in hybrid lanthanum hexaboride-graphene-silicon field emitters


Secure Advanced Monitoring Systems

UC San Diego researchers discovered that the current technology for these applications were simply not suitable for the needed purpose, and the systems were over-priced for the functionality they offered. UCSD researchers invented, built, and implemented, an advanced system that actually met their technical needs. This system is operational, highly functional, and helping to protect the incalculable value contained within banks of some of UCSD’s deep-freezers.
