  • Publication number: 20240076623
    Abstract: Methods for the efficient isolation and use of pluripotent adipose-derived stem cells (PASCs) are provided. In certain embodiments the methods involve providing an adipose tissue sample from which the stromal vascular fraction is co-cultured with the adipocyte fraction. PASCs can be isolated with a high degree of purification without requiring an additional cell enrichment process (e.g. cell sorting). PASCs and their conditioned media can be used for tissue regeneration within hours of harvesting the adipose tissue, and without requiring cell expansion. PASCs can grow as floating individual cells, as clusters of cells, or attached to surface(s) of the culture vessel. PASCs do not produce teratomas in vivo, nor do they induce immunorejection upon transplantation, and they achieve a high efficiency in grafting. The cells and compositions can be used for cell therapy and to screen new drugs.

  • Publication number: 20240079856
    Abstract: A method for fabricating a quality and manufacturable aperture for light emitting elements, such as vertical cavity surface emitting lasers (VCSELs), using epitaxial later overgrowth (ELO). A bar comprised of island-like III-nitride semiconductor layers is grown on a substrate using a growth restrict mask, and the island-like III-nitride semiconductor layers are fabricated into light-emitting resonating cavities across a smallest length of the bar. Apertures for the resonating cavities are also fabricated along the smallest length of the bar on wing regions of the epitaxial lateral overgrowth. Distributed Bragg reflectors (DBRs) are fabricated as mirrors for the resonant cavities on the bottom and top of the wing regions of the epitaxial lateral overgrowth.

  • Patent number: 11919880
    Abstract: Hepatitis C virus (HCV) is a human pathogen with high morbidity. The HCV NS3/4A protease is essential for viral replication and is one of top three drug targets. A number of drugs have been developed but drug resistant mutant strains emerged. Here we screened and synthesized of novel class of small molecules of Formula I or Formula IA based on tryptophan derivative scaffold as HCV NS3/4A protease inhibitors that is active against both wild type and mutant form of the protease. Only the docking hits with a binding pose that is not affected by the most frequent mutations in the active site were selected for experimental validation. The antiviral activities were evaluated by replicon and enzymatic assays. Twenty-two compounds in this series were found to inhibit HCV with EC50 values ranging between 0.64 to 63 ?M with compound 22 being the most active of this series. In protease assays, 22 had a comparable inhibition profile for the common mutant HCV GT1b D168A and the wild type enzyme.

  • Patent number: 11923471
    Abstract: An avalanche diode including a gain region and a readout structure including an n-type (p-type) region having electrically isolated segments each including implanted regions; a p-type (n-type) region; and a first electrode on each of the segments. The gain region includes a p-n junction buried between the n-type region and the p-type region: an n+-type region having a higher n-type dopant density than the n-type region; a p+-type region having a higher p-type dopant density than the p-type region; and the p-n junction between the n+-type region and the p+-type region. A bias between the first electrodes and a second electrode (ohmically contacting the p-type (n-type) region) reverse biases the p-n junction. Electrons generated in response to electromagnetic radiation or charged particles generate additional electrons m the gain region through impact ionization but the segmented region comprises a low field region isolating the gain region from the first electrodes.

  • Patent number: 11921522
    Abstract: This disclosure is directed to sub-meter level navigation accuracy for Unmanned Aerial Vehicles (UAVs) using broadband communication signals, such as cellular long-term evolution (LTE) signals. A framework and methods are provided using a receiver and controller to produce at least one of carrier phase, code phase, and Doppler frequency measurements from received LTE signals. Single difference measurements may be used to remove clock bias. LTE ENodeB clock biases are initialized using the known initial position of the UAV. The measurements are fused via an extended Kalman filter (EKF) to estimate the UAV position and integer ambiguities of the carrier phase single difference measurements. LTE signals can have different carrier frequencies and conventional algorithms do not estimate the integer ambiguities. Processes are described to detect cycle slip, where the carrier phase measurements from the LTE eNodeB multiple antenna ports are used to detect cycle slip.

  • Patent number: 11921136
    Abstract: Disclosed herein is an exceptional points of degeneracy (EPD) system with a resonator by introducing a linear time-periodic variation. In contrast, prior art systems with EPD require two coupled resonators with precise values of gain and loss and a precise symmetry of inductances and capacitances. The disclosed EPD system only requires the tuning of the modulation frequency or modulation depth, which can be easily achieved in electronic systems. The EPD is a point in a system parameters' space at which two or more eigenstates coalesce, and this leads to unique properties not occurring at other non-degenerate operating points. Also disclosed are experimental data showing the existence of a second order EPD in a time-varying single resonator and the expected sensitivity of its resonances to circuit perturbations. The disclosed EPD system exhibits structural degenerate and non-degenerate resonances whose dynamics dramatically boosts its sensitivity performance to very small perturbations.

  • Patent number: 11923969
    Abstract: A distributed hybrid algorithm that synchronizes the time and rate of a set of clocks connected over a network. Clock measurements of the nodes are given at aperiodic time instants and the controller at each node uses these measurements to achieve synchronization. Due to the continuous and impulsive nature of the clocks and the network, we introduce a hybrid system model to effectively capture the dynamics of the system and the proposed hybrid algorithm. Moreover, the hybrid algorithm allows each agent to estimate the skew of its internal clock in order to allow for synchronization to a common timer rate. We provide sufficient conditions guaranteeing synchronization of the timers, exponentially fast. Numerical results illustrate the synchronization property induced by the algorithm as well as its performance against comparable algorithms from the literature.
