Watermarking FPGA Bitfile for Intellectual Property Protection
Intellectual property protection (IPP) of hardware designs is the most important requirement for many Field Programmable Gate Array (FPGA) intellectual property (IP) vendors. Digital watermarking has become an innovative technology for IPP in recent years. Existing watermarking techniques have successfully embedded watermark into IP cores. However, many of these techniques share two specific weaknesses: 1) They have extra overhead, and are likely to degrade performance of design; 2) vulnerability to removing attacks. We propose a novel watermarking technique to watermark FPGA bitfile for addressing these weaknesses. Experimental results and analysis show that the proposed technique incurs zero overhead and it is robust against removing attacks
Constraining the Skyrme effective interactions and the neutron skin thickness of nuclei using isospin diffusion data from heavy ion collisions
Recent analysis of the isospin diffusion data from heavy-ion collisions based
on an isospin- and momentum-dependent transport model with in-medium
nucleon-nucleon cross sections has led to the extraction of a value of MeV for the slope of the nuclear symmetry energy at saturation density.
This imposes stringent constraints on both the parameters in the Skyrme
effective interactions and the neutron skin thickness of heavy nuclei. Among
the 21 sets of Skyrme interactions commonly used in nuclear structure studies,
the 4 sets SIV, SV, G, and R are found to give values
that are consistent with the extracted one. Further study on the correlations
between the thickness of the neutron skin in finite nuclei and the nuclear
matter symmetry energy in the Skyrme Hartree-Fock approach leads to predicted
thickness of the neutron skin of fm for Pb, fm for Sn, and fm for Sn.Comment: 10 pages, 4 figures, 1 Table, Talk given at 1) International

Country branding emerging from citizens’ emotions and the perceptions of competitive advantage: the case of Malaysia
This article aims to examine the elements of country branding from the perspectives of a country’s citizens. In this exploration, the study constructs their views toward the country using both emotion (affect) and perceptions of competitive advantage and subsequently conceptualizes and tests a framework of internal country-branding elements. Using a survey approach, the study generated a total sample of 445 respondents across Malaysia. Structural equation modeling was employed to analyze the data and to test the hypotheses. Findings indicate that Malaysia can be portrayed favorably through export, human capital, culture and heritage, and political efforts. While some elements (human capital, culture and heritage, and politics) are important to foster positive emotions among its citizens, others (export, human capital, and politics) are considered as key tools to build competitive advantage. Implications exist for tourism marketers and policy makers, as the study highlights the importance of branding toward a country’s citizens and revealing the specific preferences affecting the citizens’ emotions and perceptions toward competitive advantage
Equation of state of the hot dense matter in a multi-phase transport model
Within the framework of a multi-phase transport model, we study the equation
of state and pressure anisotropy of the hot dense matter produced in central
relativistic heavy ion collisions. Both are found to depend on the
hadronization scheme and scattering cross sections used in the model.
Furthermore, only partial thermalization is achieved in the produced matter as
a result of its fast expansion
