An anomaly detection system includes multiple sensors fixed within a user-selected environment to measure environmental conditions and wirelessly transmit data corresponding to the environmental conditions to a main device. The main device includes circuitry encoded with instructions from a trained machine learning model to identify one or more anomalies from the data received from the sensors. The main device transmits data related to the anomalies and the environmental conditions to a cloud storage via a plurality of wired and wireless connections. The cloud storage wirelessly relays the data to a user device. The user device, based on user's feedback, relays a feedback signal, via the cloud storage, to the trained machine learning model, where the feedback signal is incorporated into the trained machine learning model for the purpose of retraining.

Luminescent concrete compositions containing cement, fine aggregates such as sand, and a phosphor such as strontium aluminate. Glow-in-the-dark concrete products made therefrom and methods of producing such concrete products are also specified. The glow-in-the-dark concrete products demonstrate good mechanical strength (e.g. compressive strength) and skid resistance. The addition of phosphorescent strontium aluminate provides luminance that persists for up to 10 hours to the concrete products.

Abrégé
A method of treating a COVID-19 infection including administering to a subject in need thereof an effective amount of a composition, where the composition includes silica nanoparticles, superparamagnetic iron oxide nanoparticles (SPIONs), chitosan, cisplatin, ribavirin, and an angiotensin-converting enzyme 2 (ACE-2). The SPIONs and ACE-2 are dispersed on an outer surface of the silica nanoparticles. The chitosan at least partially wraps around the outer surface of the silica nanoparticles. The cisplatin and ribavirin are in pores of the silica nanoparticles. The particles of the composition are monodisperse, and spherical, and have an average diameter of 70-100 nanometers (nm).

Abrégé
A device for predicting and monitoring epileptic seizures includes a wearable electrodermal activity (EDA) sensor that measures skin conductance, a wearable respiration rate (RR) sensor and a microcontroller. The microcontroller receives high-frequency phasic signals from the EDA sensor and compares the phasic signals to a first skin conductance threshold value and a second skin conductance threshold value to determine when to actuate a warning of an epi-seizure condition of a patient. When a warning alarm is generated, the microcontroller compares a number of breaths per minute to respiration rate thresholds to determine when a patient is in a seizure state. The microcontroller transmits warning and seizure mode alerts to a epi-seizure telemedicine application stored on a smart device to alert a caregiver of an incipient or on-going epileptic seizure.

Abrégé
A composite nanomaterial of ZnO impregnated by, e.g., a green copper phthalocyanine compound (CuPc) can be an efficient solar light photocatalyst for water remediation. The composite may include hollow shell microspheres and hollow nanospheres of CuPc-ZnO. CuPc may function as a templating and/or structure modifying agent, e.g., for forming hollow microspheres and/or nanospheres of ZnO particles. The composite can photocatalyze the degradation of organic pollutants such as crystal violet (CV) and 2,4-dichlorophenoxyacetic acid as well as microbes in water under solar light irradiation. The ZnO—CuPc composite can be stable and recyclable under solar irradiation.
