Ion-beam radiation damage to DNA by investigation of free radical formation and base damage

March 1, 2020
Author(s)
Melis Kant, Pawel Jaruga, Erdem Coskun, Samuel Ward, Alexander Stark, David Becker, Amitav Adhikary, Michael Sevilla, Miral M. Dizdar
This work investigated the physicochemical processes and DNA base products involved in Ne-22 ion- beam (ca. 1.4 GeV) radiation damage to hydrated (12 waters/nucleotide) highly polymerized salmon sperm DNA. For this purpose, approximately 12 small (ca. 10

Measurement of PARP1 in human tissues by liquid chromatography tandem mass spectrometry

March 1, 2020
Author(s)
Erdem Coskun, Gamze Tuna, Pawel Jaruga, Alessandro Tona, Onur Erdem, Miral M. Dizdar
Poly(ADP ribose) polymerase 1 (PARP1) is a multifunctional DNA repair protein of the base excision repair pathway and plays a major role in the repair of DNA strand breaks and in replication and transcriptional regulation among other functions. Mounting

Nd Ordering, Cluster Formation, and the Origin of Negative Magnetization in NdMn 0l8 Fe 0.2 O 3=d

March 1, 2020
Author(s)
D. M. Pajerowski, Jr. C. A. Escanhoela, D. Haskel, Timothy R Prisk, M. D. Frontzek, D. Phelan, Jr. Mihalik, M. Mihalik
The orthorhombic pseudo-perovskite series NdMn 1-xFe xO 3+δ has negative magnetization, i.e. magnetization directed opposite to an applied field under certain conditions, for x = 0.3 and x=0.25. We have investigated the microscopic origin of this

Perovskite-Related ReO 3 -Type Structures

March 1, 2020
Author(s)
Hayden A Evans, Yue Wu, Ram Seshadri, Anthony K. Cheetham
ReO 3-type structures can be described as ABX 3 perovskites in which the A-cation site is unoccupied. They therefore have the general composition BX 3, where B is normally a cation and X is a bridging anion. The chemical diversity of such structures is

Sixfold Enhancement of Superconductivity in a Tunable Electronic Nematic System

March 1, 2020
Author(s)
Christoper Eckberg, Daniel J. Campbell, Tristin Metz, John Collini, Halyna Hodovanets, Tyler Drye, Peter Zavalij, Morten H. Christensen, Rafael M. Fernandes, Sangjun Lee, Peter Abbamonte, Jeffrey W. Lynn, Johnpierre Paglione
The electronic nematic phase, wherein electronic degrees of freedom lower the crystal rotational symmetry, is a common motif across a number of high-temperature superconductors. However, understanding the role and influence of nematicity and nematic

Quantitative Bright-Field Microscopy Combined with Deep Neural Networks Predict Live Tissue Function

February 29, 2020
Author(s)
Carl Simon Jr., Nicholas J. Schaub, Petru S. Manescu, Sarala Padi, Mylene Simon, Peter Bajcsy, Nathan A. Hotaling, Joe Chalfoun, Mohamed Ouladi, Qin Wan, Kapil Bharti, Ruchi Sharma
Progressive increases in the number of cell therapies in the preclinical and clinical phases has prompted the need for reliable and non-invasive assays to validate transplant function in clinical biomanufacturing. Here, we developed a robust

A Graph Database Approach to Wireless IIoT Work-cell Performance Evaluation

February 28, 2020
Author(s)
Richard Candell, Mohamed T. Hany, Yongkang Liu, Karl R. Montgomery, Sebti Foufou
The work-cell is an essential industrial environment for testing wireless communication techniques in factory automation processes. A new testbed was recently designed and developed to facilitate such studies in work-cells by replicating various data flows
