Abstract: Lithium-sulfur (Li—S) batteries using unconventional-phase transition metal dichalcogenides (TMDs), such as 1T?-WS2, as the functional layer on the separator. The unique atomic structure of 1T?-WS2 facilitates the strong immobilization and excellent catalytic ability in the conversion of polysulfide intermediates during cycling. Furthermore, the self-assembling of 1T?-WS2 greatly decreases the internal porosity, minimizing the uptake of electrolyte, which can further guarantee the performance of the battery under lean electrolyte conditions. As a result, a cell based on the 1T?-WS2 shows improved performances under high sulfur loading and lean electrolyte conditions. A cell with 12 mg cm?2 mass loading of S with only 25% oversized Li metal anode can deliver specific energy of at least 400 Wh kg?1 and 820 Wh L?1, which is among the best of reported Li—S batteries.

Abstract: A method and system for estimating the ground state energy of a quantum Hamiltonian. The disclosed algorithm may run on any hardware and is suited for early fault tolerant quantum computers. The algorithm employs low-depth quantum circuits with one ancilla qubit with classical post-processing. The algorithm first draws samples from Hadamard tests in which the unitary is a controlled time evolution of the Hamiltonian. The samples are used for evaluating the convolution of the spectral measure and a filter function, and then inferring the ground state energy from this convolution. Quantum circuit depth is linear in the inverse spectral gap and poly-logarithmic in the inverse target accuracy and inverse initial overlap. Runtime is polynomial in the inverse spectral gap, inverse target accuracy, and inverse initial overlap. The algorithm produces a highly-accurate estimate of the ground state energy with reasonable runtime using low-depth quantum circuits.

Abstract: An online concierge identifies orders to shoppers, allowing shoppers to select orders for fulfillment. The online concierge system may generate batches that include multiple orders, allowing a shopper to select a batch to fulfill multiple orders. As orders are continuously being received, delaying identification of orders to shoppers may allow greater batching of orders. To allow greater opportunities for batching, the online concierge system estimates a benefit for delaying identification of an order by different time intervals and predicts an amount of time to fulfill the order. The online concierge system then delays assigning orders for which there is a threshold benefit for delaying and selects a time interval for delaying identification of the order that does not result in greater than a threshold likelihood of a late fulfillment of the order.

Abstract: A method for shale gas exploitation includes performing horizontal drilling operation on an area to be constructed, forming a crack around a horizontal drill hole wall by shaped charge perforation; expanding the crack around a horizontal hole hydraulic fracturing, and extracting methane gas after a fracturing fluid is discharged; after methane gas is reduced, performing in-situ combustion explosion fracturing on the methane involved in horizontal drilling; thereafter continuing to expand the crack in the horizontal drill hole such that methane continues to seep out, and continuing extracting methane; repeating combustion explosion fracturing and extraction operations, so as to increase combustion explosion cracking permeability, and greatly enhance the exploitation effect of shale gas. The method is suitable for fracturing reconstruction of unconventional oil and gas reservoirs such as shale gas reservoirs, coal seam gas reservoirs and tight sandstone gas reservoirs.

Abstract: A routing information management method adapted for a layer-3 switch is proposed. For each ARP entry in an ARP table, a processor assigns to the ARP entry an aging reference parameter that is identical to a quantity of those routing entries in an IP routing table whose next hop IP addresses are identical to the IP address of the ARP entry, and removes those ARP entries whose aging reference parameters are zero. For each routing entry in the IP routing table, when the next hop IP address of the routing entry is absent from the ARP table, the processor makes the routing entry serve as an inactive routing entry, proactively sends an ARP request for the inactive routing entry, and updates the ARP table based on a piece of ARP information received externally.
