Publication number: 20200151712Abstract: Disclosed is a cryptocurrency system (“Arbitrum”) that supports smart contracts without the scalability and privacy limitations of previous systems such as Ethereum. Arbitrum, like Ethereum, allows parties to create smart contracts by using code to specify the behavior of a virtual machine (VM) that implements the contract's functionality. Arbitrum uses mechanism design to incentivize parties to agree off-chain on what a VM would do, so that the Arbitrum verifiers need only verify digital signatures to confirm that parties have agreed on a VM's behavior. In the event that the parties cannot reach unanimous agreement off-chain, Arbitrum still allows honest parties to advance the VM state on-chain. If a party tries to lie about a VM's behavior, the verifier (or miners) will identify and penalize the dishonest party by using a highly efficient challenge-based protocol that exploits features of the Arbitrum virtual machine architecture.Type: ApplicationFiled: September 5, 2019Publication date: May 14, 2020Applicant: The Trustees of Princeton UniversityInventors: Edward W. Felten, Steven Goldfeder, Harry Kalodner

Publication number: 20200150063Abstract: Disclosed are a procedure and system for live monitoring of staining quality and heavy metal diffusion during electron microscopy preparation protocols for biological samples. The disclosed approach employs x-rays via, e.g., a commercially available micro-CT device, to observe and measure the diffusion and distribution of the heavy metals during conventional biological sample staining procedures for electron microscopy. This allows one to observe and check the quality and homogeneity of the staining without damaging or destroying the sample.Type: ApplicationFiled: November 12, 2019Publication date: May 14, 2020Applicant: The Trustees of Princeton UniversityInventors: Adrian A.

Publication number: 20200109988Abstract: Disclosed herein is an all-digital phase and timing correction procedure for coherent averaging in dual-comb and multiheterodyne spectroscopy—applicable to any dual-comb spectroscopy setup. It can account for large frequency/phase instabilities of the used sources, yielding a significant reduction of the noise pedestal and an increase in signal-to-noise ratio (SNR) of the radio frequency (RF) beat notes. This technique is computationally efficient and can be conveniently implemented either as a post-processing algorithm or in a real-time data acquisition and processing platform without the necessity of adding any additional optical elements to the dual-comb spectroscopy system. By implementing this technique, the performance of any comb- or comb-like-source-based DCS system with a sufficient degree of mutual coherence between the optical modes can be improved in terms of SNR and number of spectroscopically-usable RF beat notes.Type: ApplicationFiled: May 15, 2018Publication date: April 9, 2020Applicant: The Trustees of Princeton UniversityInventors: Lukasz STERCZEWSKI, Jonas WESTBERG, Gerard WYSOCKI

Publication number: 20200095569Abstract: A system and method for reversibly controlling clustering of proteins around an engineered multivalent nucleus is disclosed. The system and method utilize clustering, which may be controlled by light activation or deactivation. The system and method enable the spatiotemporal control of protein supramolecular assemblies, including liquid-like droplets under some conditions, and solid-like gels under other conditions.

Publication number: 20200079823Abstract: Disclosed is a high-throughput transcriptional assay format in Actinomycete bacteria, and Streptomyces spp. in particular, that leverages eGFP, inserted both at a neutral site and inside the biosynthetic cluster of interest, as a read-out for secondary metabolite synthesis. Using this approach, a silent gene cluster in Streptomyces albus J1074 was induced. The cytotoxins etoposide and ivermectin were revealed as potent inducers, allowing the isolation and structural characterization of nearly 20 novel small molecule products of the chosen cluster. One of these molecules is a novel antifungal, while several others inhibit a cysteine protease implicated in cancer. Studies addressing the mechanism of induction by the two elicitors led to the identification of a pathway-specific transcriptional repressor that silences the gene cluster under normal growth conditions.Type: ApplicationFiled: May 11, 2018Publication date: March 12, 2020Applicant: The Trustees of Princeton UniversityInventors: Mohammad R.
