Abstract: A control system for controlling extraction of landfill gas from a landfill via a gas extraction system comprising well piping, the landfill gas having a first temperature when extracted, the control system comprising: a gas composition chamber coupled to the well piping and comprising at least one sensor configured to measure one or more characteristics of a landfill gas sample in the gas composition chamber; a temperature control mechanism configured to heat the landfill gas sample in the gas composition chamber to a second temperature at least a threshold amount greater than the first temperature; and a controller configured to control the at least one sensor to measure the one or more characteristics of the landfill gas sample in the gas composition chamber when a temperature of the landfill gas sample in the gas composition chamber is at least the threshold amount greater than the first temperature.

Abstract: A heterogeneous procatalyst includes a preformed heterogeneous procatalyst and a metal-ligand complex. The preformed heterogeneous procatalyst includes a titanium species and a magnesium chloride (MgCl2) support. The metal-ligand complex has a structural formula (L)aM(Y)m(XR2)b, where M is a metal cation; each L is a neutral ligand or (?O); each Y is a halide or (C1-C20)alkyl; each XR2 is an anionic ligand in which X is a heteroatom or a heteroatom-containing functional group and R2 is (C1-C20)hydrocarbyl or (C1-C20) heterohydrocarbyl; n is 0, 1, or 2; m is 0-4; and b is 1-6. The metal-ligand complex is overall charge neutral. The heterogeneous procatalyst exhibits improved average molecular weight capability. A catalyst system includes the heterogeneous procatalyst and a cocatalyst. Processes for producing the heterogeneous procatalyst and processes for producing ethylene-based polymers utilizing the heterogeneous procatalyst are also disclosed.

Abstract: Described herein are devices, systems, and methods for trapping single-cell lysates in sealed, microwells capable of printing RNA on glass or capturing RNA on beads. These provide efficient, inexpensive manipulation of RNA from individual cells suitable for single-cell transcriptomics on a large scale. Also described are dual barcode capture beads and merged barcode capture beads.

Abstract: Disclosed are systems and methods for culturing systemic bioengineered tumor models, including osteosarcoma cells or breast adenocarcinoma cells derived from patients. The model includes the tumor cells on host tissues such as bone, liver, lung, and heart tissue, wherein the bone, liver, lung, and heart tissue are separated by endothelial barriers. Beneath the endothelial barriers the tissues are connected via circulation containing secreted factors and cells (e.g., tumor/immune cells).

Abstract: Single-cell multi-omics by co-encapsulating a single cell with two beads, the first an RNA barcoding bead having barcoded mRNA capture primer oligonucleotides attached on the bead surface; and the second a DNA barcoding bead having two types of oligonucleotides releasably attached to the surface: (1) barcoded adapter oligonucleotides that are complementary to oligonucleotides bound to the transposase that are eventually incorporated into gDNA fragments and (2) polyadenylated barcoded oligonucleotides containing the same barcode sequence as the adapters. In addition, integrated analysis of RNA and protein, including intracellular protein, from individual cells using similar co-encapsulation of a single cell, an RNA barcoding bead, and with/without a specific or non-specific protein binding bead in a microwell, to avoid protein fixation by first lysing the cell to liberate intracellular contents, and then capturing protein either on a solid surface or in solution with barcoded affinity reagents.
