In this study we present an analysis of a novel practical m-plane GaN three and two quantum well terahertz quantum cascade lasers (THz QCLs) using Non-equilibrium Green’s function (NEGF). We examined the performance of this unique designs, exhibiting their capabilities for high-temperature operation and extended Terahertz frequency coverage. For the three quantum well structure, at low temperatures, a peak gain of 87 cm-1 was observed, which decreased to ~ 24 cm-1 at 300 K, still above the expected losses. The research shows lasing at ~6 THz, outperforming standard GaAs THz-QCLs’ frequency coverage. This work provides valuable insights into the development of advanced GaN-based THz QCLs with above room temperature performance and expanded frequency coverage, bridging the gap in Terahertz technology.

Coordinated inauthentic behavior (CIB) by malicious actors operating across independent organizations undermines the integrity of financial systems, digital markets, and public discourse. While each organization can detect malicious actors coordinating on its associated domain, cross-domain detection remains a challenge due to privacy regulations, competitive boundaries, and fragmented data. This work introduces a privacy-preserving framework for cross-organization CIB detection that infers coordination through encrypted analysis of behavioral dynamics rather than shared content or explicit links between coordinating members. Specifically, we show that synchronized bursts of user activity provide a robust signal of coordination even when content and identifiers are concealed. The framework combines R'enyi Differential Privacy and Homomorphic Encryption to allow organizations to contribute encrypted inter-event activity distributions of suspected accounts. These representations are then used to compute private similarity scores, which serve as a key signal for detecting coordinated inauthentic behavior. We evaluate the framework on multi-platform datasets and demonstrate that coordination remains detectable under strict privacy budgets. The results highlight a new path for privacy-preserving behavioral inference, enabling organizations to expose coordinated manipulation without compromising user privacy or data sovereignty.

The invention relates to novel proteinoid-based nanocapsules (NCs) designed for non-invasive drug delivery to the retina via topical administration (eye drops). The nanocapsules are synthesized from tailored amino acid–based polymers that self-assemble into hollow nano-sized particles capable of encapsulating therapeutic agents. These biodegradable, non-toxic, and customizable nanocapsules enable penetration across ocular barriers and delivery of drugs to posterior eye tissues, including the retina and choroid, thereby potentially replacing invasive intravitreal injections. The invention includes specific proteinoid compositions optimized for enhanced retinal penetration, safety, and drug-loading capacity.

The invention consists of (i) discovery that tumor metastasis of breast and other forms of cancer can be prevented by inhibiting the interaction between cortactin and the non-receptor tyrosine kinase Pyk2, (ii) a 19-mer peptide derived from the Pyk2 sequence is an inhibitor of this interaction, (iii) administration of this peptide significantly reduces metastasis in malignant cell-lines and in immune-competent mice, and (iv) additional peptides with improved inhibition profiles were derived in a structure-based approach.

Systems and methods are described for secure communication to facilitate encrypted transmission of data between a transmitting device (encoder) and a receiving device (decoder), leveraging quandle algebra. An example system includes an encoder, a decoder, and a communication channel. The encoder may generate a ciphertext (c) based on a message (x), an encoding variable (y), and a public encryption key (e), wherein, c=x▹y. The cipher text (c) is then transmitted, via the communication channel, to the decoder. The decoder may receive the ciphertext (c) via the communication channel and generate a deciphered form (x’) of the message (x) based on the ciphertext (c), the encoding variable (y), and a private encryption key (f), wherein, x^'=c◃y, and ▹and ◃ are binary operations that satisfy axioms of a quandle and/or a rack. The proposed methods inherits the strength of the famous RSA scheme and improves upon it using a multi-step process involving rational numbers instead of integers.

The invention provides a method for designing and implementing frequency-domain filter functions in quantum systems through dynamically invariant control fields. Unlike traditional dynamical decoupling methods, which derive spectral properties post hoc from time-domain sequences, this method analytically constructs time-dependent Hamiltonians that realize arbitrary spectral responses, including multi-band and phase-sensitive profiles. The approach utilizes the formalism of dynamical invariants to ensure exact state evolution and robustness to drive-amplitude errors. Experimental implementation on nitrogen-vacancy (NV) centers in diamond demonstrates enhanced coherence preservation and signal selectivity beyond conventional control protocols.

The present invention relates to optical and quantum sensing systems that utilize synthetic temporal gauge fields to perform ultrafast and noise-resilient measurements. More specifically, the invention describes an interferometric sensing architecture in which an external signal is converted into a gauge-invariant temporal phase, analogous to a temporal Aharonov–Bohm (AB) effect, and is subsequently measured through interferometric or correlation-based detection. In the disclosed system, correlated optical modes are generated using a parametric process, such as four-wave mixing or parametric amplification, forming a temporal interferometric structure. The optical modes propagate through a dispersive or time-lens-based section, in which a time-dependent modulation is applied. This modulation produces a synthetic temporal gauge potential that induces a relative phase shift between the correlated modes. The accumulated phase depends on the temporal profile of the modulation and constitutes a gauge-invariant quantity analogous to the Aharonov–Bohm phase in conventional electromagnetic systems. After the gauge-induced phase is acquired, the optical modes are recombined in a second parametric or interferometric stage. The output signal depends on the accumulated gauge phase and is detected using intensity, interferometric, or correlation-based measurements. Because the sensed quantity is a gauge-invariant phase, the system exhibits reduced sensitivity to local perturbations, amplitude noise, and certain environmental fluctuations, thereby enabling more robust and accurate measurements. The invention enables sensing of a wide variety of external signals, including but not limited to: ultrafast phase or delay variations, time-dependent electrical or optical modulation signals, radio-frequency or microwave waveforms, dynamic optical path variations. The sensing mechanism is fundamentally different from conventional phase or amplitude modulation techniques, as the measured signal is encoded in a synthetic gauge phase rather than in a local field interaction. This approach allows ultrafast operation, compatibility with both classical and quantum optical regimes, and the possibility of enhanced sensitivity through parametric or correlation-based readout. The disclosed architecture may be implemented using temporal SU(1,1) interferometers, time-lens systems, dispersive optical elements, electro-optic modulators, or other time-dependent phase modulation devices. The system can operate with classical optical fields, single photons, or entangled photon pairs, and may be configured for various sensing, metrology, and signal-processing applications.

Modern computer chips are increasingly stacked in advanced 2.5D/3D dense packages, making it impossible to test individual layers for radiation damage in space. Our invention embeds tiny memory-based sensors directly inside the chip package. These sensors simultaneously detect multiple types of radiation damage through a single, simple measurement. A built-in AI mechanism analyzes the sensor data and automatically reconfigures the system to keep it operational, potentially trading performance for survival as radiation accumulates. This allows ordinary commercial chips to operate reliably in space without expensive space-grade components.
