Intraocular pressure (IOP) measurements comprise an essential tool in modern medicine for the early diagnosis of glaucoma, the second leading cause of human blindness. The world's highest prevalence of glaucoma is in low-income countries. Current diagnostic methods require experience in running expensive equipment as well as the use of anesthetic eye drops. We present herein a remote photonic IOP biomonitoring method based on deep learning of secondary speckle patterns, captured by a fast camera, that are reflected from eye sclera stimulated by an external sound wave. By combining speckle pattern analysis with deep learning, high precision measurements are possible. The method was tested under artificially varying eye pressures on a series of 24 pig eyeballs, found to be similar to human eyes. As a low-cost procedure, it has the potential to meet clinical needs in low- and middle-income countries and at points of care everywhere.

We predicted that the negative permittivity can be used for attraction of like charged particles instead of repulsion. This can lead to creation of electron-electron pairs similar to Cooper pairs (with possibilities to reach superconductivity at room temperature). This phenomenon can be used also for nucleus-nucleus pairing with possibilities of low energy nuclear fusion. Negative values of permittivity we propose to achieve due to the localized surface plasmon resonances in metamaterials. These resonance frequencies can be varied over a wide range by application of static magnetic or electric fields.

Mapping tip-enhanced near-field optical signals by modulating the tip-sample distance at multiple frequencies simultaneously and observing the near-field heterodyne beating signal, between the two near field modulated “light-fields”. This heterodyne beat signal only occurs from the near-field interaction and therefore it provides a means of detecting the near-field, without background signals from the incident light excitation interacting in the far-field with the sample or with the AFM probe.

A system comprising one or more spectrometers coupled to one or more battery cells, wherein the one or more spectrometers generate one or more electrical signals in response to an incident source in proximity to the one or more battery cells, and wherein the electrical signals comprise spectral data associated with emissions from the one or more battery cells. The system further comprising a computing device configured to receive the spectral data and one or more operating variables, compare the spectral data with reference spectral data and the one or more operating variables, and determine a presence of abnormal operating conditions of the one or more battery cells based on the comparison.

The invention relates to a stimuli-responsive carrier system that enables controlled, transient, and reversible release of therapeutic and other functional substances. The system is based on a polymeric matrix crosslinked by redox-active metal ions, whose mechanical properties and diffusivity can be reversibly modulated by externally applied stimuli, such as ascorbic acid (Vitamin C) or visible light irradiation. Upon application of the stimulus, the matrix transiently softens and becomes permeable, allowing controlled release of incorporated cargos. Removal of the stimulus results in autonomous recovery of the matrix to its original, mechanically robust state, halting further release. The dissipative mechanism enables repeated on-demand release cycles from a single carrier depot without permanent degradation. The invention has broad applicability, including medical, ocular, industrial, and environmental uses. The invention is a collaborative effort of HUJI (Prof. Itamar Willner) and BIU (Prof. Yossi Mandel). BIU will share parts of the invention that are related solely to ocular use of the application.

Systems and methods are described for quantum information retrieval. An example system may include a quantum cloning unit, a photon number splitting (PNS) unit, and a weak measurement unit to enhance the accuracy and reliability of quantum state estimations without introducing substantial decoherence. The quantum cloning unit may be used to generate approximate clones of a qubit. If the qubit is a multi-photon state qubit, then the photon number splitting (PNS) unit may be used to intercept the multi-photon state qubit and reflect a single photon from the multi-photon state qubit, which may then be subjected to quantum cloning. These qubits and qubit clones may then be subjected to weak measurements, which provides detailed analysis with minimal disturbance to quantum properties such as superposition and entanglement.

The invention enables new x-ray imaging methods that provide not just the shape of the image but also the atomic species it is composed of. In addition, the apparatus based our approach requires lower dose than conventional x-ray imaging and improve the visibility and the signal-to-noise of the image leading to images that are clearer than in conventional x-ray imaging systems.

The invention includes a tiny optical element in the form of two or three dimensional arrays, that retains its expected performance over a large range of temperatures. As opposed to any other optical element in which the optical properties always vary with the temperature, the current invention engineers each unit cell in the array from two or more materials with opposite thermo-optic coefficients, in order to construct a device with no temperature dependence. Hence, these types of temperature invariant metasurfaces- can operator exactly the same even if the temperature changes dramatically

A simple technique to generate cluster quantum states of light which are universal resources for quantum computing is disclosed. The technique uses two components. First, a broadband source of Einstein-Podolsky-Rosen entangled states, a.k.a. two-mode-squeezed states, generated in an optical frequency comb from a monochromatic pump field. Second, a phase modulator (typically by electro-optic effect) operating at frequencies multiple of the comb mode spacing. Using only these two components, cluster quantum states can be generated that have one-, two-, three-, or higher-dimensional graphs. The unprecedented compactness of this technique paves the way to implementing quantum computing on chip using quantum nanophotonics.

We have developed a facile way for fabrication of transparent fluorescent thin films with different colors. The emission is efficient and by using 488 nm laser beam 3 different emission layers can be excited (530 nm, 570 nm and 620 nm). Thus, we one can get a green, yellow, orange and white emission (combination of 2 colors) from those transparent layers. The films are very homogenous (no crystals etc.) and we can cover large areas of tens of centimeters. Our development is based on hydrogel nanoparticles (HNPs) to which different type of emitters have been chemically attached so to have liquid dye solutions which can be easily deposited on surfaces. Following this technique aggregation of the dye molecules is prevented resulted as stable high quantum yield emitters.
