    The university technology licensing research phenomena has mostly been addressed from seller (university) point of view while the technology buyer (licensee) has mostly been ignored. This paper reverses this research trend and addresses the university technology licensing phenomenon from the buyers’ perspectives. To explore the criteria most crucial to the university technology licensing decision making process, the author undertook a national survey addressing the most influential technology licensing executive in the US. In addition, the survey also addresses several questions about the licensing of university technologies, and shed insights on why some university technologies get licensed while many others do not.The university technology licensing research phenomena has mostly been addressed from seller (university) point of view while the technology buyer (licensee) has mostly been ignored.

    US corporations have long recognized university related scientific research as an important source of long term economic growth and technological innovation. This dynamic involvement with industry has drastically increased the university technology transfer and licensing activities, and has stretched the human and financial resources of Technology Management and Licensing Offices of many US universities. This research provides a mechanism that can aid in the complex process of properly assessing university-owned technologies and intellectual properties, to identify those with licensing and commercialization potential for the pursuit of truly important breakthrough discoveries. This research focuses on the university technology licensing and commercialization process from the perspectives of those licensing professionals whose firms\u27 activities are engaged in licensing-in university technologies. The objectives of this research are to: 1.Identify the decision factors and licensing determinants that influence or impact the licensing and commercialization of university technologies. 2.Build and conduct a survey among those licensing professionals involved in the technology licensing process to determine the relative importance of each of the licensing determinants identified in the literature review, and their most current and up to date selection criteria for technologies they license. 3.Develop a framework to assist the University Technology Management & Transfer Office\u27s personnel and other stakeholders in the assessment of the potential viability of the university technologies for licensing and commercialization

    Get PDF
    This study was undertaken in order to: 1) evaluate the performance of thermoplastic striping materials, 2) compare their performance on both portland cement concrete and bituminous concrete pavements to that of conventional traffic paints, and 3) to evaluate the economics of thermoplastics in terms of cost per mile per day of useful life. The performance of two brands of thermoplastic striping materials and conventional traffic paints applied at nine test sites in both rural and urban areas is reported herein. Application procedures, site locations, repair histories and materials specifications are included. Accumulative costs for each material at all sites for a seven-year period are summarized in Table 4. The performance of thermoplastics placed on bituminous concrete was superior to that placed on portland cement concrete pavements. Epoxy primers were of aid in providing adherence of thermoplastics to portland cement concrete pavements; however, the epoxies were not capable of penetrating surface laitance. Visibility of the thermoplastic stripes decreased with age due to accumulation of road scum

    Supersymmetric Sum Rules for Electromagnetic Multipoles

    Get PDF
    We derive model independent, non-perturbative supersymmetric sum rules for the magnetic and electric multipole moments of any theory with N=1 supersymmetry. We find that in any irreducible N=1 supermultiplet the diagonal matrix elements of the l-multipole moments are completely fixed in terms of their off-diagonal matrix elements and the diagonal (l-1)-multipole moments.Comment: 10 pages, plain Te

    A low-power recursive I/Q signal generator and current driver for bioimpedance applications

    Get PDF
    This brief presents a power-efficient quadrature signal generator and current driver application-specific integrated circuit (ASIC) for bioimpedance measurements in an electrical impedance tomography system for monitoring lung function. The signal generator is realized by a digital recursive signal oscillator with the ability of generating quadrature signals over a wide frequency range. The generated in-phase signal is applied to a current driver. It uses a balanced current-mode feedback architecture that monitors the output current through a feedback loop to minimize common-mode voltage build-up at the injection site. The quadrature signals can be used for I/Q demodulation of the measured bioimpedance. The ASIC was designed in TSMC 65 nm technology occupying an area of 0.21 mm2. The current driver can generate up to 0.7 mA current up to 200 kHz and consumes 2.7 mW power using ±0.8 V supplies

    κ(BEDTTTF)2X\kappa-(BEDT-TTF)_2X organic crystals: superconducting versus antiferromagnetic instabilities in an anisotropic triangular lattice Hubbard model

    Full text link
    A Hubbard model at half-filling on an anisotropic triangular lattice has been proposed as the minimal model to describe conducting layers of κ(BEDTTTF)2X\kappa-(BEDT-TTF)_2X organic materials. The model interpolates between the square lattice and decoupled chains. The κ(BEDTTTF)2X\kappa-(BEDT-TTF)_2X materials present many similarities with cuprates, such as the presence of unconventional metallic properties and the close proximity of superconducting and antiferromagnetic phases. As in the cuprates, spin fluctuations are expected to play a crucial role in the onset of superconductivity. We perform a weak-coupling renormalization-group analysis to show that a superconducting instability occurs. Frustration in the antiferromagnetic couplings, which arises from the underlying geometrical arrangement of the lattice, breaks the perfect nesting of the square lattice at half-filling. The spin-wave instability is suppressed and a superconducting instability predominates. For the isotropic triangular lattice, there are again signs of long-range magnetic order, in agreement with studies at strong-coupling.Comment: 4 pages, 5 eps figs, to appear in Can. J. Phys.

    This paper reports on preliminary qualitative evaluation of relationship between color change and water activity (aw) of date (Phoenix dactylifera L., var. Mech-Degla) fruit tablets (DFTs) as natural supplement, in view to optimize their storage conditions. Eight types of DFTs were obtained, according to: i) mean particle size (225 and 282 μm) of the used fruit powder, and ii) compression pressure (5, 10, 15 and 20 kN) applied during the tableting process. The experimental adsorption curves, determined at 25°C using static-gravimetric method, were fitted to GAB (Guggenheim–Anderson–de Boer) and BET (Brunauer–Emmett–Teller) models. Results showed that the DFT color is significantly sensitive to aw since beyond the aw threshold value of 0.44, the DFT color changes from light grey to dark brown, independently of the particle size of fruit powder and compression pressure. Concerning the isotherm modeling, the both models tested seem especially suitable (R≈0,96 0.3≤MRE≤5 and SE≈0.03) for describing the experimental data for DFT obtained under a compression pressure of 5 kN from date fruit powder with mean particle size of 225 μm. The DFT color stability is considerably influenced by the environmental humidity. Considering the importance of color for consumer acceptance, the study deserves to be deepened concerning the quantitative analysis of the color (CIELab system), packaging of the tablets, etc.В данной статье сообщается о предварительной качественной оценке взаимоотношения между изменением цвета и активностью воды (aw) таблеток из фиников (Phoenix dactylifera L., var. Mech-Degla) (DFT) как натуральной добавки с целью оптимизации условий их хранения. Было получено восемь типов DFT в соответствии с: i) средним размером частиц (225 и 282 μм) используемого порошка плодов и ii) давлением сжатия (5, 10, 15 и 20 kN), примененном во время процесса таблетирования. Экспериментальные кривые адсорбции, определенной при 25°C, используя статический гравиметрический анализ, были приспособлены к моделям GAB (Гугенгейма — Андерсона — Де Бура) и BET (Брунауэр, Эммет и Теллер). Результаты показали, что цвет DFT в большой степени чувствителен к aw, т. к. за пределами порогового уровня aw порошка плодов цвет DFT изменяется от светло серого до темно коричневого, независимо от размера частиц порошка плодов и давления сжатия. Что касается изотермического моделирования, то обе тестированные модели особенно пригодны (R≈0,96 0,3≤MRE≤5 и SE≈0,03) для описания экспериментальных данных для DFT, полученных при давлении сжатия 5 kN из порошка фиников со средним размером частиц 225 μм. Влажность окружающей среды оказывает значительное влияние на стабильность цвета DFT. Что касается, значения цвета для принятия потребителями, то исследование необходимо углубить в отношении количественного анализа цвета (система CIELab), упаковки таблеток и т. д

    OBJECTIVE: To determine whether Tai Chi Chuan or ballroom dancing promotes better performance with respect to postural balance, gait, and postural transfer among elderly people. METHODS: We evaluated 76 elderly individuals who were divided into two groups: the Tai Chi Chuan Group and the Dance Group. The subjects were tested using the NeuroCom Balance Master¯ force platform system with the following protocols: static balance tests (the Modified Clinical Tests of Sensory Interaction on Balance and Unilateral Stance) and dynamic balance tests (the Walk Across Test and Sit-to-stand Transfer Test). RESULTS: In the Modified Clinical Test of Sensory Interaction on Balance, the Tai Chi Chuan Group presented a lower sway velocity on a firm surface with open and closed eyes, as well as on a foam surface with closed eyes. In the Modified Clinical Test of Sensory Interaction on Unilateral Stance, the Tai Chi Chuan Group presented a lower sway velocity with open eyes, whereas the Dance Group presented a lower sway velocity with closed eyes. In the Walk Across Test, the Tai Chi Chuan Group presented faster walking speeds than those of the Dance Group. In the Sit-to-stand Transfer Test, the Tai Chi Chuan Group presented shorter transfer times from the sitting to the standing position, with less sway in the final standing position. CONCLUSION: The elderly individuals who practiced Tai Chi Chuan had better bilateral balance with eyes open on both types of surfaces compared with the Dance Group. The Dance Group had better unilateral postural balance with eyes closed. The Tai Chi Chuan Group had faster walking speeds, shorter transfer times, and better postural balance in the final standing position during the Sit-to-stand Test
