Lehigh University is an American private research university located in Bethlehem, Pennsylvania. It was established in 1865 by businessman Asa Packer and has grown to include studies in a wide variety of disciplines. Its undergraduate programs have been coeducational since the 1971–72 academic year. As of 2014, the university had 4,904 undergraduate students and 2,165 graduate students. Lehigh is considered one of the twenty-four Hidden Ivies in the Northeastern United States.Lehigh is ranked 12th in the nation, according to The Wall Street Journal, in college return on investment . The university has over 680 faculty members; awards and honors recognizing Lehigh faculty and alumni include the Nobel Prize, the Pulitzer Prize, Fulbright Fellowship, and membership in the American Academy of Arts & science and the National Academy of science.The university has four colleges: the P.C. Rossin College of Engineering and Applied Science, the College of Arts and science, the College of Business and Economics, and the College of Education. The College of Arts and science is the largest college today, home to roughly 40% percent of the university's students. The university offers a variety of degrees, including Bachelor of Arts, Bachelor of Science, Master of Arts, Master of Science, Master of Business Administration, Master of Engineering, Master of Education, and Doctor of Philosophy.

One aspect of the invention provides a method of controlling execution of a computer program. The method comprises the following runtime steps: parsing code to identify one or more indirect branches; creating a branch ID data structure that maps an indirect branch location to a branch ID, which is the indirect branchs equivalence class ID; creating a target ID data structure that maps a code address to a target ID, which is an equivalence class ID to which the address belongs; and prior to execution of an indirect branch including a return instruction located at an address: obtaining the branch ID associated with the return address from the branch ID data structure; obtaining the target ID associated with an actual return address for the indirect branch from the target ID data structure; and comparing the branch ID and the target ID.

An ultrathin plasmonic subtractive color filter in one embodiment includes a transparent substrate and an ultrathin nano-patterned film formed on the substrate. A plurality of elongated parallel nanoslits is formed through the film defining a nanograting. The nanoslits may be spaced apart at a pitch selected to transmit a wavelength of light. The film is formed of a material having a thickness selected, such that when illuminated by incident light, surface plasmon resonances are excited at top and bottom surfaces of the film which interact and couple to form hybrid plasmon modes. The film changes between colored and transparent states when alternatingly illuminated with TM-polarized light or TE-polarized light, respectively. In one configuration, an array of nanogratings may be disposed on the substrate to form a transparent display system.

A thin film organic photovoltaic device or solar cell in one embodiment includes an organic active bilayer and an ultrathin two-dimensional metallic nanogrid as a transparent conducting electrode which receives incident light. The nanogrid excites surface plasmonic resonances at an interface between the nanogrid and active bilayer from the incident light to enhance photon absorption in the active bilayer below the nanogrid. In another embodiment, spatially separated nanograting electrodes may alternatively be formed by double one-dimensional nanogratings disposed on opposite sides of the organic active bilayer. The spatially separated nanogratings may be oriented perpendicular to each other.

Provided herein are conductive glass-metal compositions, as well as methods of making and using such compositions. In one example, the compositions include gold (Au) doped lithium-borate glasses shown to exhibit a transition from ionic to electronic conduction within the same sample. This is achieved via appropriate heat treatment, and particularly by heat treatment after annealing, wherein the post-annealing heat treatment is performed at temperatures below the glass transition temperature (T
