A simple yet time-optimal and linear-space algorithm for shortest unique substring queries
(Elsevier, 2015)We revisit the problem of finding shortest unique substring (SUS) proposed recently by Pei et al. (2013) [12]. We propose an optimal O(n) time and space algorithm that can find an SUS for every location of a string of size ... -
Joint subcarrier and antenna state selection for cognitive heterogeneous networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers, 2015)Reconfigurable antennas (RA) offer an emerging technology that allows wireless devices to alter their antenna states determined by different radiation patterns to maximize received signal strength. In this paper, we consider ... -
Effects of ultrasound frequency on nanodroplet-mediated histotripsy
(Elsevier Science, 2015)Nanodroplet-mediated histotripsy (NMH) is a targeted ultrasound ablation technique combining histotripsy with nanodroplets that can be selectively delivered to tumor cells for targeted tumor ablation. In a previous study, ... -
A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
(Institute of Electrical and Electronics Engineers, 2015)In this paper, we introduce a windowing technique, which provides optimal time-frequency containment and maximal adjacent channel interference (ACI) rejection for orthogonal frequency-division multiplexing (OFDM)-based ... -
A three-mask process for fabricating vacuum-sealed capacitive micromachined ultrasonic transducers using anodic bonding

S-layer fusion protein as a tool functionalizing emulsomes and CurcuEmulsomes for antibody binding and targeting
(Elsevier, 2015)Selective targeting of tumor cells by nanoparticle-based drug delivery systems is highly desirable because it maximizes the drug concentration at the desired target while simultaneously protecting the surrounding healthy ... -
Theoretical analysis of the co-existence of LTE-A signals and design of an ML-SIC Receiver
(Institute of Electrical and Electronics Engineers, 2015)The increasing number of mobile devices and the demand for large throughput requiring applications has hampered access to the limited frequency spectrum. The goal of this work is to introduce a new degree of freedom to the ... -
Emulsomes meet s-layer proteins: An emerging targeted drug delivery system
(Bentham Science Publishers, 2015)Here, the use of emulsomes as a drug delivery system is reviewed and compared with other similar lipidic nanoformulations. In particular, we look at surface modification of emulsomes using S-layer proteins, which are ... -
Cracking more password hashes with patterns
(Institute of Electrical and Electronics Engineers, 2015)It is a common mistake of application developers to store user passwords within databases as plaintext or only as their unsalted hash values. Many real-life successful hacking attempts that enabled attackers to get ... -
Toward building hybrid biological/in silico neural networks for motor neuroprosthetic control
