Energy is transmitted to a body lumen or passageway in the form of pulsed electric fields (PEFs) and in a manner which provides focal therapy. In some embodiments, PEFs are delivered through independent electrically active electrodes of an energy delivery body, typically in a monopolar fashion. Such delivery concentrates the electrical energy over a smaller surface area, resulting in stronger effects than delivery through an electrode extending circumferentially around the lumen or passageway. It also forces the electrical energy to be delivered in a staged regional approach, mitigating the effect of preferential current pathways through the surrounding tissue. Focal delivery of PEFs can provide increased tissue lethality by employing precise timing and sequencing of energy delivery to the electrodes.

Described herein are monopolar treatment delivery systems, and methods for use therewith. Such a system can include an energy delivery electrode, a dispersive electrode, a reference electrode, and a generator in electrical communication with the energy delivery electrode, the dispersive electrode, and the reference electrode. The generator is configured to deliver an impedance measurement signal to target tissue using the energy delivery electrode and the dispersive electrode, while the energy delivery electrode is proximate to the target tissue and the dispersive electrode is remote from the target tissue. The generator is also configured to measure a voltage between the energy delivery electrode and the reference electrode, and to monitor impedance of the target tissue based on a current of the impedance measurement signal and the voltage between the energy delivery electrode and the reference electrode …

We explore the design of climate stress tests to assess and manage macroprudential risks from climate change in the financial sector. We review the climate stress scenarios currently employed by regulators, highlighting the need to (a) consider many transition risks as dynamic policy choices, (b) better understand and incorporate feedback loops between climate change and the economy, and (c) further explore compound risk scenarios in which climate risks co-occur with other risks. We discuss how the process of mapping climate stress scenarios into financial firm outcomes can incorporate existing evidence on the effects of various climate-related risks on credit and market outcomes. We argue that more research is required to (a) identify channels through which plausible scenarios can lead to meaningful short-run impact on credit risks given typical bank loan maturities, (b) incorporate bank-lending responses to …

The report, prepared for the U.S. Department of Energy West Valley Demonstration Project office (DOE-WVDP), summarizes the environmental protection program at the WVDP for calendar year (CY) 2022. Monitoring and surveillance of the facilities used by the DOE are conducted to verify protection of public health and safety and the environment. The report is a key component of DOE’s effort to keep the public informed of environmental conditions at the WVDP. The quality assurance protocols applied to the environmental monitoring program ensure the validity and accuracy of the monitoring data. In addition to demonstrating compliance with environmental laws, regulations, and directives, evaluation of data collected in 2022 continued to indicate that WVDP activities pose no threat to public health or safety, or to the environment.

Tissue treatment systems and methods are disclosed. In an embodiment, a tissue treatment system includes a LV signal generator, a HV signal generator, and a controller. The LV signal generator is used to produce a LV tissue impedance measurement signal, and the HV signal generator is used to produce a HV tissue treatment signal having a voltage that is at least five times greater than a voltage of the LV tissue impedance measurement signal. The controller controls when the HV tissue treatment signal produced using the HV signal generator, and when the LV tissue impedance measurement signal produced using the LV signal generator, are delivered to patient tissue via an active electrode and a return electrode. The LV tissue impedance measurement signal is used to estimate the impedance of the patient tissue, which is used to control the voltage and/or current of the HV tissue treatment signal.

The present invention provides systems, methods, and devices for electroporation-based therapies (EBTs). Embodiments provide patient-specific treatment protocols derived by the numerical modeling of 3D reconstructions of target tissue from images taken of the tissue, and optionally accounting for one or more of physical constraints or dynamic tissue properties. The present invention further relates to systems, methods, and devices for delivering bipolar electric pulses for irreversible electroporation exhibiting reduced or no damage to tissue typically associated with an EBT-induced excessive charge delivered to the tissue.
