Old-growth forests provide unique habitat features and landscape functions compared to younger stands. The goals of many forest management plans in the Pacific Northwest include increasing the area of late-successional and old-growth forests.

The purpose of this note is to provide a starting point for discussion of fire hazard reduction treatments that meet the full range of management objectives, including budget priorities. Thoughtful design requires an understanding not only of the physical and biological outcomes, but also the costs and potential revenues of applying variations of fire hazard reduction treatments in a wide range of stand conditions. This analysis was done with My Fuel Treatment Planner software and provides estimates of cost and net revenue from fire hazard reduction treatments on 18 dry forest stands from 9 national forests in the Western United States. The data and software tools used in this analysis are all available, so these analyses can be easily modified to address a wider range of treatments and conditions.

The upcoming primary election is a pivotal moment for Iowa City. For the past several months, I have talked to people throughout the district who are ready for change. They believe their Democratic representative should show up for people throughout the community, especially those in need. They expect a legislator from Iowa’s bluest district to be a leader in the party, raising money to support Democratic candidates up and down the ticket and making the strongest possible case for progressive legislation. They are ready to start now in building the future of the Democratic Party and state government in Iowa. And I am honored that they are putting their trust in me.

There is a lot at stake in this election. The coronavirus has laid bare and magnified preexisting inequities — inequities brought about by the Legislature’s disinvestment in education, health care, and worker rights and safety. Small businesses are now struggling to survive, when for years the state has been giving large corporations hundreds of millions of dollars in tax credits. Water quality, climate change and gun violence still need our attention, even as we continue to invest in keeping people safe from COVID-19. We have never needed strong leadership more than we do now.

I will be a champion for progressive values because I have lived them. I know how hard it can be for people to get by even when they work hard. I grew up in a trailer in rural Florida. Neither of my parents graduated high school. My dad was a construction worker who suffered for years with emphysema. When his health insurance was canceled, my family had to choose between paying for his medicine and everything else. Fortunately, public education gave me the opportunity for a better life. My teachers taught me well and helped me to apply to college. Public university tuition was affordable then, and I was able to work my way through engineering school and law school.

Today, I am a law professor, an environmental engineer and a mother. I believe I have the skills, energy and passion that Iowa City needs at this critical point in time. I will show up for every member of our community and fight for a better future for all of Iowa.

It’s time for change in Iowa City. Please vote for me in House District 85 and help to build the future that Iowa deserves.

Christina Bohannan is a candidate in the Democratic primary for Iowa House District 85.

Please join me in voting for Christina Bohannan for Iowa House of Representatives District 85. Christina is an energetic and passionate leader. She has broad experience as a law professor, an environmental engineer, and an advocate for diversity, equity and inclusion. These experiences give her a unique perspective and the ability to comprehend legislative issues from many different points of view. She sees the big picture and knows that she can support economic growth and small business while also advocating for basic human rights and fairness.

Christina shows up for people all over the community and is an advocate for people of color, immigrants, and others from disadvantaged or marginalized backgrounds. She is a strong voice for labor, collective bargaining rights, and a living wage. She will stand up against wage theft and other unfair practices.

In the state Legislature, Christina will be a fearless and energetic advocate for each and every member of her district. She also will be a dedicated and collaborative partner with local government. This is why so many local officials are endorsing her.

Please join me and many others in voting for Christina Bohannan for Iowa House District 85.

Iowa City

The next ten years will prove to be one of the most challenging eras in Iowa history.

Whether we meet those challenges with Iowa-smart, progressive responses will depend largely on the quality of legislators we elect to office.

Christina Bohannan, Democratic candidate for the Iowa House of Representatives, would be a remarkably talented and hardworking legislator, if given the opportunity to serve.

The daughter of blue-collar parents.

Trained as an environmental engineer.

A professor of law at the University of Iowa College of Law.

The former president of the Iowa Faculty Senate.

A mother.

These life experiences inform Christina Bohannan’s pragmatic progressivism.

If elected, she has the skill set to get good things done for Iowa.

Please join me in supporting Democrat Christina Bohannan for the House District 85 seat in the June 2 primary election.

We show that the complex absorbing potential (CAP) method for computing scattering resonances applies to the case of exponentially decaying potentials. That means that the eigenvalues of $-Delta + V - iepsilon x^2$, $|V(x)|leq e^{-2gamma |x|}$ converge, as $ epsilon o 0+ $, to the poles of the meromorphic continuation of $ ( -Delta + V -lambda^2 )^{-1} $ uniformly on compact subsets of $ extrm{Re},lambda>0$, $ extrm{Im},lambda>-gamma$, $arglambda > pi/8$.

Predicting the spatial configuration of gas molecules in nanopores of shale formations is crucial for fluid flow forecasting and hydrocarbon reserves estimation. The key challenge in these tight formations is that the majority of the pore sizes are less than 50 nm. At this scale, the fluid properties are affected by nanoconfinement effects due to the increased fluid-solid interactions. For instance, gas adsorption to the pore walls could account for up to 85% of the total hydrocarbon volume in a tight reservoir. Although there are analytical solutions that describe this phenomenon for simple geometries, they are not suitable for describing realistic pores, where surface roughness and geometric anisotropy play important roles. To describe these, molecular dynamics (MD) simulations are used since they consider fluid-solid and fluid-fluid interactions at the molecular level. However, MD simulations are computationally expensive, and are not able to simulate scales larger than a few connected nanopores. We present a method for building and training physics-based deep learning surrogate models to carry out fast and accurate predictions of molecular configurations of gas inside nanopores. Since training deep learning models requires extensive databases that are computationally expensive to create, we employ active learning (AL). AL reduces the overhead of creating comprehensive sets of high-fidelity data by determining where the model uncertainty is greatest, and running simulations on the fly to minimize it. The proposed workflow enables nanoconfinement effects to be rigorously considered at the mesoscale where complex connected sets of nanopores control key applications such as hydrocarbon recovery and CO2 sequestration.

We address the problem of handling provenance information in ELHr ontologies. We consider a setting recently introduced for ontology-based data access, based on semirings and extending classical data provenance, in which ontology axioms are annotated with provenance tokens. A consequence inherits the provenance of the axioms involved in deriving it, yielding a provenance polynomial as an annotation. We analyse the semantics for the ELHr case and show that the presence of conjunctions poses various difficulties for handling provenance, some of which are mitigated by assuming multiplicative idempotency of the semiring. Under this assumption, we study three problems: ontology completion with provenance, computing the set of relevant axioms for a consequence, and query answering.

Randomized Numerical Linear Algebra (RandNLA) uses randomness to develop improved algorithms for matrix problems that arise in scientific computing, data science, machine learning, etc. Determinantal Point Processes (DPPs), a seemingly unrelated topic in pure and applied mathematics, is a class of stochastic point processes with probability distribution characterized by sub-determinants of a kernel matrix. Recent work has uncovered deep and fruitful connections between DPPs and RandNLA which lead to new guarantees and improved algorithms that are of interest to both areas. We provide an overview of this exciting new line of research, including brief introductions to RandNLA and DPPs, as well as applications of DPPs to classical linear algebra tasks such as least squares regression, low-rank approximation and the Nystr"om method. For example, random sampling with a DPP leads to new kinds of unbiased estimators for least squares, enabling more refined statistical and inferential understanding of these algorithms; a DPP is, in some sense, an optimal randomized algorithm for the Nystr"om method; and a RandNLA technique called leverage score sampling can be derived as the marginal distribution of a DPP. We also discuss recent algorithmic developments, illustrating that, while not quite as efficient as standard RandNLA techniques, DPP-based algorithms are only moderately more expensive.
