Chain Conformation near the Buried Interface in Nanoparticle-Stabilized Polymer Thin Films

October 10, 2017
Author(s)
Deborah A. Barkley, Naisheng Jiang, Mani Sen, Maya K. Endoh, Jonathan G. Rudick, Tadanori Koga, Yugang Zhang, Oleg Gang, Guangcui Yuan, Sushil K. Satija, Daisuke Kawaguchi, Keiji Tanaka, Alamgir Karim
It is known that when nanoparticles are added to polymer thin films, they often migrate to the film-substrate interface and form an "immobile interfacial layer", which has been believed as the origin of suppression of dewetting. We here report an

Domain Formation in the Type-II/1 Superconductor Niobium: Interplay of Pinning, Geometry, and Attractive Vortex-Vortex Interaction

October 10, 2017
Author(s)
Tommy Reimann, Michael Schulz, David F. Mildner, Markus Bleuel, Annie Brulet, Ralph P. Harti, Georg Benka, Andreas Bauer, Peter Boni, Sebastian Muhlbauer
Vortex attraction which can cause a bundling of vortices has been observed in a multitude of type-II superconductors, While its underlying mechanisms have been extensively studied, the morphology of the emerging vortex superstructure has only been weakly

Exploratory Lens Model of Decision-Making in a Potential Phishing Attack Scenario

October 10, 2017
Author(s)
Franklin Tamborello, Kristen K. Greene
Phishing, the transmission of a message spoofing a legitimate sender about a legitimate subject with intent to perform malicious activity, causes a tremendous and rapidly-increasing amount of damage to American information systems and users annually. This

Liquid Structure with Nano-Heterogeneity Promotes Cationic Transport in Concentrated Electrolytes

Oleg Borodin, Liumin Suo, Mallory Gobet, Xiaoming Ren, Fei Wang, Antonio Faraone, Jing Peng, Marco Olguin, Marshall Schroeder, Michael S. Ding, Eric Gobrogge, Arthur von Wald Cresce, Stephen Munoz, Joseph Dura, Steve Greenbaum, Chunsheng Wang, Kang Xu
Using molecular dynamics simulations, small angle neutron scattering and a variety of spectroscopic techniques, we evaluated the ion solvation and transport behaviors in aqueous electrolytes containing bis(trifluoromethane sulfonyl)imide (LiTFSI). We

vPROM: vSwitch Enhanced Programmable Measurement in SDN

October 10, 2017
Author(s)
An Wang, Yang Guo, Songqing Chen, Fang Hao, T.V. Lakshman, Douglas C. Montgomery, Kotikalapudi Sriram
Network programmability is a salient feature of Software Defined Networking (SDN), which allows users to program network applications with the perception that the underlying network is a single device. While still at an early stage of development, SDN

Vulnerability and Robustness of Civil Infrastructure Systems to Hurricanes

October 10, 2017
Author(s)
Shuoqi Wang, Dorothy Reed
Civil infrastructure systems play an important role in community resilience. Without proper functioning of the infrastructure, especially power delivery, society will not recover quickly from disruptive events, such as hurricanes. In this paper, the

Nanowire Aptasensors for Electrochemical Detection of Cell-Secreted Cytokines

October 9, 2017
Author(s)
Ying Liu, Ali Rahimian, Sergiy Krylyuk, Tam Vu, Bruno Crulhas, Gulnaz Stybayeva, Dong-Sik Shin, Albert Davydov, Alexander Revzin, Meruyert Imanbekova
Cytokines are small proteins secreted by immune cells in response to pathogens/infections; therefore these proteins can be used in diagnosing infectious diseases. For example, release of a cytokine interferon (IFN)-γ from T-cells is used for blood-based

Organizational Practices in Cryptographic Development and Testing

October 9, 2017
Author(s)
Julie Haney, Simson L. Garfinkel, Mary Theofanos
Organizations developing cryptographic products face significant challenges, including usability and human factors, that may result in decreased security, increased development time, and missed opportunities to use the technology to its fullest potential

Wrinkling-to-delamination transition in thin polymer films on compliant substrates

October 9, 2017
Author(s)
Adam J. Nolte, Jun Y. Chung, Chelsea S. Davis, Christopher Stafford
Compressing a thin, stiff film attached to a thick, compliant substrate can lead to a number of different modes of mechanical deformation depending upon the material properties of the system. In this article we explore direct transitions from surface

Adaptive synchronization reference selection for out-of-coverage Proximity Services (ProSe)

October 8, 2017
Author(s)
Samantha M. Gamboa Quintiliani, Fernando J. Cintron, David W. Griffith, Richard A. Rouil
Proximity services (ProSe) is a Long Term Evolution Advanced (LTE-A) feature that allows User Equipments (UEs) to communicate without the need of routing the data throughout the network. In this paper, we studied the synchronization protocol used by ProSe

Cryptocurrency Smart Contracts for Distributed Consensus of Public Randomness

October 7, 2017
Author(s)
Peter M. Mell, John M. Kelsey, James Shook
Most modern electronic devices can produce a random number. However, it is dicult to see how a group of mutually distrusting entities can have con dence in any such hardware-produced stream of random numbers, since the producer could control the output to

Redox-active Nanomaterials for Nanomedicine Applications

October 6, 2017
Author(s)
Christopher Sims, Shannon Hanna, Daniel A. Heller, Christopher Horoszko, Monique Johnson, Antonio Montoro Bustos, Vytas Reipa, Kathryn Riley, Bryant C. Nelson
Nanomedicine utilizes the remarkable properties of nanomaterials for the diagnosis, treatment, and prevention of disease. Many of these nanomaterials have been shown to have robust antioxidative properties, potentially functioning as strong scavengers of

Surface plasmon polariton laser based on a metallic trench Fabry-Perot resonator

October 6, 2017
Author(s)
Wenqi Zhu, Ting Xu, Haozhu Wang, Cheng Zhang, Parag B. Deotare, Amit K. Agrawal, Henri J. Lezec
Recent years have witnessed growing interest in the development of lasers with small footprint for their potential applications in small-volume sensing and on-chip optical communications. Surface-plasmons – electromagnetic modes evanescently confined to

Surprising Loss of Three-Dimensionality in Low-Energy Spin Correlations on Approaching Superconductivity in Fe 1+y Te 1-x Se x
