Abstract
Phonon engineered, lanthanide doped upconverting nanoparticles with very low phonon energies and tunable methods of synthesis that adjust OA:OM ratio and reaction temperature are provided. Low phonon energy KPb2X5 (X=Cl, Br) upconverting nanoparticles, both doped and undoped, exhibit dramatically suppressed multiphonon relaxation, enhancing upconversion emission from higher lanthanide excited states and enabling room temperature observation of avalanche like upconversion by Nd3+ ions. Intrinsic optical bistability (IOB) of the materials can provide bit level functionality to all optical computing. The IOB of Nd3+ doped nanocrystals, which are either bright or dark at the same excitation power based on power history, illustrate the functionality. High contrast switching and IOB are enabled via the photon avalanche process, which sustains population inversion between the ground and the first excited 4fN states of Nd3+ ions. The IOB of these nanocrystals can be controlled by temporal pump modulation and can store information.

Abstract
Disclosed are systems and methods for motor control using piecewise affine modelling. An electronic controller may determine current values for a motor in a rotational reference frame. Each current value may be associated with a dimension of a set of dimensions of the rotational reference frame. The electronic controller may further determine, based on the current values, a flux linkage value for each of the set of dimensions of the rotational reference frame using a piecewise affine map. The electronic controller may further determine a target flux linkage value for each of the set of dimensions of the rotational reference frame. The electronic controller may then control a power switching network coupled between a power supply and the motor based on the flux linkage values and the target flux linkage values.

Abstract
Systems and methods of performing temperature swing solvent extraction (TSSE) descaling of produced water and desalination of high-salinity brines, e.g., those having a total dissolved solids (TDS) greater than about 250,000 ppm are capable of producing descaled water products including less than about 5% weight percent TDS. The brine/produced water feedstreams and combined with a solvent having temperature-dependent water solubility at a temperature TL. Water is extracted from the feedstream into the solvent to form a water-in-solvent extract component and a raffinate component, from which a solid phase can be precipitated as more water is portioned in the solvent and basicity increases. Heating of the water-in-solvent extract component reduces the solubility of the water therein, producing a biphasic mixture of dewatered solvent and descaled water that can be separated. Because these systems and methods do not require a phase change of water, these products are achieved with significantly higher energy efficiencies when compared to evaporation-based thermal methods.

Abstract
Treatments and methods for inhibiting late Na current use fibroblast growth factor homologous factor (FHF), an endogenous channel modulator, to inhibit late Na current with high potency. A minimal effector domain is engineered within FHF (the “FHF-inhibiting-X-region” (FixR)) as a peptide inhibitor of late Na current that may be delivered intracellularly, for example as a cell-penetrating peptide, or via viral or plasmid delivery. As a non-limiting example, human adenovirus type 5 may be genetically modified with the sequence 5′-ATGGCTGCGGCGATAGCCAGCTCCTTGATCCGGCAGAAGCGGCAGGCGAGGGAG TCCAACAGCGACCGAGTGTCGGCCTCCAAGCGCCGCTCCAGCCCCAGCAAAGAC GGGCGCTCC-3′ (SEQ ID NO: 1). As pathophysiological impact of late Na current extends beyond cardiac myocytes to other physiological settings, including neurons of the central and peripheral nervous system and skeletal muscle, these treatments and methods provide potential therapeutic avenues for a range of human ailments, including cardiac conditions, neurological/neuropsychiatric disorders, and skeletal muscle conditions. Neurological/neuropsychiatric disorders include, for example, epilepsy and autism spectrum disorders, pain-related diseases, and myotonia.

Abstract
The method of treating obesity and targeting adipose tissue in a patient may use injection of a polycationic polymer, such as polyamidoamine (PAMAM) generation 3 (P-G3) or a PCL-g-PAMAM Denpol, that when delivered intraperitoneally, selectively targets visceral adiposity due to its high charge density. P-G3 treatment of obese mice inhibits visceral adiposity, increases energy expenditure, prevents obesity, and alleviates associated metabolic dysfunctions. The extracellular matrix of adipose tissue is enriched with glycosaminoglycans, the known biomacromolecules with the strongest negative charge. P-G3 uncouples adipocyte lipid synthesis and storage from adipocyte development, creating adipocytes with normal functions but that are deficient in hypertrophic growth. The visceral fat distribution of P-G3 is further enhanced by modifying P-G3 with cholesterol to form lipophilic nanoparticles, effective in treating obesity. This strategy provides a method to target visceral adiposity, and cationic nanomaterials useful for treating metabolic diseases or for delivery of additional treating agents.

Inventor
Hillman, Elizabeth M.C.
Abstract
Multiple fluorophores within a sample can be imaged by merging a plurality of beams from different wavelength light sources of excitation light into a single path, directing the excitation light into the sample, and detecting light emitted by the fluorophores within the sample on two different arrays of pixels (e.g., two regions within a single camera sensor chip). The light sources are activated during respective timeslots, and captured image data is processed. For at least one of the timeslots, the processing of the image data comprises using the image data captured using the first array of pixels to detect a presence of a given fluorophore, and using the image data captured using the second array of pixels to detect a presence of a different fluorophore. This arrangement enables a system that includes only N light sources to image more than N fluorophores.
