Title: Method for direct conversion of carbon dioxide to dialkyl carbonates using ethylene oxide as feedstock
Inventor: PANCHAL CHANDRAKANT B
IPC: C07C68/04
Filed: 2020-12-01
Abstract: A method for co-production of high purity dimethyl carbonate and mono-ethylene glycol by applying a reactor, such as a membrane reactor and/or an adsorbent-catalytic reactor by capturing and reacting carbon dioxide with methanol and ethylene oxide. Carbon dioxide may be recovered from primary sources (utilities and industrial processes) by a membrane or solid adsorbent, and subsequently converted to an intermediate hydroxy-ethyl- methyl carbonate by reacting with ethylene oxide and methanol. For high-purity carbon dioxide (obtained by carbon capture technologies or from an ethanol fermentation process), the membrane reactor is replaced with a catalytic reactor for direct conversion of carbon dioxide to hydroxy-ethyl-methyl carbonate by reacting with ethylene oxide and methanol. The hydro-ethyl-methyl carbonate is further reacted with methanol for conversion to dimethyl carbonate. A combination of heterogeneous and homogeneous catalysts is implemented for an effective conversion of carbon dioxide. An integrated reactive distillation process using side reactors is used for facilitating catalytic reaction for production of high purity dimethyl carbonate.

Title: Noise contrastive estimation for collaborative filtering
Inventor: VOLKOVS MAKSIMS
IPC: H04N21/258
Filed: 2019-09-03
Abstract: A recommendation system models unknown preferences as samples from a noise distribution to generate recommendations for an online system. Specifically, the recommendation system obtains latent user and item representations from preference information that are representations of users and items in a lower-dimensional latent space. A recommendation for a user and item with an unknown preference can be generated by combining the latent representation for the user with the latent representation for the item. The latent user and item representations are learned to discriminate between observed interactions and unobserved noise samples in the preference information by increasing estimated predictions for known preferences in the ratings matrix, and decreasing estimated predictions for unobserved preferences sampled from the noise distribution.

Title: Artificial promiscuous t helper cell epitopes as immune stimulators for synthetic peptide immunogens
Inventor: WANG CHANG YI
IPC: A61K39/39
Filed: 2019-12-19
Abstract: The present invention is directed to novel promiscuous and artificial T helper cell epitopes (Th epitopes) designed to provide optimum immunogenicity of a target antigenic site. The target antigenic site can include a B cell epitope, a CTL epitope, a peptide hapten, a non-peptide hapten, or any immunologically reactive analogue thereof. The disclosed Th epitopes, when covalently linked to a target antigenic site in a peptide immunogen construct, elicit a strong B cell antibody response or an effector T cell response to the target antigenic site. The Th epitopes are immunosilent on their own, i.e., little, if any, of the antibodies generated by the peptide immunogen constructs will be directed towards the Th epitope, thus allowing a very focused immune response directed to the targeted antigenic site. The promiscuous artificial Th epitopes provide effective and safe peptide immunogens that do not generate inflammatory, anti-self, cell-mediated immune responses following administration.

Inventor: MASLOFF BRIAN
IPC: C04B38/10
Filed: 2021-08-11
Abstract: Implementations described and claimed herein provide a process for creating a low-buoyancy cellular concrete that may include cement, water, and various surfactants including hydrophilic additives to produce the low-buoyancy cellular concrete. The low-buoyancy cellular concrete wet mix maintains its cellular properties while it is placed and cures. After curing, water may be absorbed into the low buoyancy cellular concrete via a combination of physical and chemical characteristics. An open cell structure of capillaries facilitates wicking action of water into the low buoyancy cellular concrete via capillary channeling (through the cementitious matrix between the micro-bubbles, and in some cases into the micro-bubbles as well). Further, the hydrophilic additive in the foam surfactant facilitates absorption of water into the low buoyancy cellular concrete through diminished surface tension at an interface of the cellular concrete and a body of water and at and between the microbubbles.
