摘要： Antennas with increased bandwidth are provided. The bandwidth of an antenna can be increased by feeding it at a single point through N sides with a 1:N power divider, where N is an integer greater than 1. This bandwidth enhancement approach can be applied to different types of antennas, and with this design approach the bandwidth of an antenna can be increased without increasing its footprint.

摘要： Antenna arrays with three-dimensional (3D) conformal radiating elements are provided, as well as methods of manufacturing and methods of using the same. An array can include a ground plane and a plurality of unit cells disposed thereon. Each unit cell can include a 3D conformal radiating element. The 3D conformal radiating elements can be, for example, patches (e.g., circular 3D patches), dipoles, or loops, and each radiating element is conformal on a hemispherical shape.

摘要： Antenna arrays, antenna elements for said arrays, and methods of fabricating and using the same are provided. Antenna arrays can be operated at multiple frequencies, such as at two different frequencies for Radio Detection And Ranging (RADAR) communication and for imaging applications. Each antenna element can include a driven patch that is excited directly and a parasitic patch that is excited by the driven patch.

摘要： Dual-band antenna systems and methods of fabricating and using the same are provided. A tunable dual-polarization (left-hand circular polarized (LHCP) and right-hand circular polarized (RHCP)) antenna can be used both for L-band (1.215 gigahertz (GHz)-1.85 GHz) and Ka-band (32.3 GHz-34.2 GHz) operation. The antenna system can be an embedded antenna system, which can be used for 3U CubeSats, with full polarization diversity able to operate in two widely spaced frequency bands (L-band and Ka-band) of the spectrum. The antenna system can include three layers, including a top substrate, a bottom substrate, and a ground plane disposed between the top substrate and the bottom substrate.

摘要： The subject invention pertains to a completely new pile splicing system called Grouted Sleeve Coupler Splice (GSCS) for Precast Concrete Piles (PCPs) as an innovative alternative splicing method for connecting driven PCP segments. The provided splicing method is applicable for preplanned situations and provides a durable, labor-friendly, rapid, and economical foundation construction method. In this system, to improve the structural performance, the entire sleeve coupler and a portion of the dowels are partially debonded in short lengths from surrounding concrete. This connection system is novel in conjunction with PCPs and for connecting separate precast pile segments. The provided system offers a completely unique and new method of connecting and splicing PCP segments and other prismatic prefabricated piles.

摘要： The subject invention provides methods for fabricating electrochemical aptamer-based (E-AB) sensors with enhanced sensitivity, signal-to-noise ratios, LOD, and improved stability and reproducibility. The subject invention also provides methods for aptamer immobilization on the surface of the electrode, which favors sufficient spacing between aptamers at the microscale to achieve optimal target recognition, folding, and signal transduction. The E-AB sensors of the subject invention provide superior sensing regardless of the sequence or structure of the bound aptamers or the physiochemical properties of the target.

摘要： Systems and methods for quantifying the duration of S1 and/or S2 heart sounds, in order to identify markers of heart failure and/or lung failure, are provided. Cardiac cycles containing S1 and S2 sound can be identified in a phonocardiogram and normalized. In order to quantify S1 and S2 sound length, the envelope of the absolute value of the signal can be obtained for each cycle. The sound waves of two components can be separated using the identified single sound wave. These features can be correlated to measures of heart failure and/or lung failure.

摘要： The subject invention provides compounds, peptidomimetics, and methods of synthesis thereof. The subject invention provides the synthesis and use of guanidino acids and/or poly guanidino acids not only as vehicles for drug delivery but as toolbox for drug discovery. The peptidomimetic of the subject invention comprises oligo(guanidino acid)s or poly(guanidino acid)s with guanidines as peptide bond surrogates. The incorporation of the guanidine as amide bond surrogates offers significant differences in polarity, hydrogen bonding capability, and acid-base character.

摘要： The present invention provides assays and methods for studying DNA topology and topoisomerases. The assays and methods utilize a circular plasmid DNA comprising one or more hairpin structures and the ability of T5 exonuclease (T5E) to digest the circular plasmid DNA in a specific configuration. The assays and methods can be used as a high throughput screening for inhibitors of, for example, DNA gyrases and DNA topoisomerases I for anticancer drug and antibiotics discovery.
