Fungi are key players in the health, diversity, and productivity of forest ecosystems in Pacific Northwest forests, as mycorrhizal associations, pathogens, decomposers, nontimber resources, and food resources for wildlife. A number of invertebrate species are associated with wood decay fungi, serve as vectors for fungal pathogens, or are fungivorous (consume fungi) and influence rates of wood decay and nutrient mineralization. In Washington and Oregon, 31 wildlife species among 8 families are fungivores, and at least 14 wildlife species disperse fungi. Down wood can provide nurse substrates for seedlings and beneficial mycorrhizal fungi, refuges from pathogenic soil fungi, sources of nutrients for decay fungi, and substrates supporting overall fungal diversity. Presence, density, distribution, and diversity of fungi are influenced by forest stand management practices, forest age class, and effects of fire. Old forests provide for a suite of rare fungi species. Old legacy trees retained during forest harvest can provide some degree of conservation of beneficial and rare fungi. Fungi can be difficult to detect and monitor; surveying for fungi at various times of the year, for multiple (at least 5) years, and by including hypogeous (belowground) samples, can improve detection rates. Studies are needed in the Pacific Northwest to quantify the amount of down wood—number of pieces, sizes, total biomass, percentage of forest floor cover, and other attributes—necessary for maintaining or restoring fungal biodiversity and viable levels of individual fungi species, especially rare species.

Although burned trees are the most visible damage following a wildfire, a forest’s soil can also be damaged. The heat generated by a wildfire can alter the soil’s physical properties and kill the fungi and bacteria that are responsible for nutrient cycling and other ecosystem services. What isn’t well understood is the extent of the heating within the soil and how quickly the soil recovers.

Millions of people head to federal lands every year for recreation—891 million visits in 2016 alone. These visits have significant economic implications, not only for restaurants, resorts, outfitters, and other businesses near recreation sites, but also for the people actually participating in outdoor recreation.

Forests of the Pacific Northwest have been an epicenter for the evolution of truffle fungi with over 350 truffle species and 55 genera currently identified. Truffle fungi develop their reproductive fruit-bodies typically belowground, so they are harder to find and study than mushrooms that fruit aboveground. Nevertheless, over the last five decades, the Corvallis Forest Mycology program of the Pacific Northwest Research Station has amassed unprecedented knowledge on the diversity and ecology of truffles in the region. Truffle fungi form mycorrhizal symbioses that benefit the growth and survival of many tree and understory plants. Truffle fruit-bodies serve as a major food souce for many forest-dwelling mammals. A few truffle species are commercially harvested for gourmet consumption in regional restaurants. This publication explores the biology and ecology of truffle fungi in the Pacific Northwest, their importance in forest ecosystems, and effects of various silvicultural practices on sustaining truffle populations. General management principles and considerations to sustain this valuable fungal resource are provided.

Serving as state representative of House District 85 for the past few years has been a privilege and an honor. I have worked hard to stand for the people of my district fighting for issues that are important to them and to the voters of Iowa City. I want to continue that advocacy and am running for another term in the Iowa House and ask for your vote.

I vigorously support adequate funding for education from pre-school to our community colleges and universities. Our young people are Iowa’s future and deserve the best start available through our excellent education system in Iowa. But we need to provide the dollars necessary to keep our teachers in the classroom so our children are prepared for whatever may lie ahead of them.

I have advocated for the fair treatment of workers in Iowa and support their right to organize. I have worked on laws for equal pay for equal work and whistle blower protection.

I am for essential funding for mental health services for Iowans of all ages. Children and adults who are struggling with mental health issues should have services available to them no matter where they live in this state.

I have fought to keep government open and accessible to Iowans. I support open records and open meetings laws to ensure that availability and transparency to all Iowans.

Keeping voting easy and accessible to voters has been a priority of mine. I support a fair and balanced redistricting system for voting in Iowa.

I have advocated to keep the bottle deposit law in place and expand it to cover the many new types of containers available.

I have worked on oversight legislation after several investigations into defrauding government which involved boarding homes, government agencies and pharmacy benefit managers (the “middleman” between pharmacies/Medicaid and the healthcare insurance companies.)

I cannot avoid mentioning the challenge of the coronavirus in Iowa. It has impacted our health, jobs, families and businesses. No one could have predicted this pandemic but as Iowans, we need to do our best to limit contact and the spread of this disease. My sincere appreciation goes to those workers on the frontlines of this crisis: the healthcare workers, store owners, businesses, farmers, teachers and workers who show up every day to keep this state moving forward. Thank you all!

There is still much work to be done to keep Iowa the great place where we live, work and raise our families. I am asking for your vote to allow me the privilege of continuing that work.

Vicki Lensing is a candidate in the Democratic primary for Iowa House District 85.

An Iowa judge has ruled unconstitutional a state law that would have blocked Planned Parenthood of the Heartland from receiving federal money to provide sex education programs to Iowa youth.

Fifth Judicial District Judge Paul Scott on Wednesday ruled the law “has no valid, ‘realistically conceivable’ purpose that serves a legitimate government interest as it is both irrationally overinclusive and under-inclusive.”

“The act violates (Planned Parenthood of the Heartland’s) right to equal protection under the law and is therefore unconstitutional,” Scott ruled in issuing a permanent injunction to prevent the law’s implementation.

House File 766, passed in 2019 by the Republican-controlled Iowa House and Senate, excluded any Iowa organization that “provides or promotes abortion” from receiving federal dollars that support sex education and related services to Iowa youth.

Planned Parenthood of the Heartland and ACLU of Iowa challenged the law, filing a lawsuit shortly after Gov. Kim Reynolds signed the bill into law.

Polk County District Court issued a temporary injunction blocking the law, which was to go into effect July 1, allowing Planned Parenthood to continue providing sex education programming throughout the past year.

The governor’s office did not immediately respond to requests for comment on the ruling.

In its lawsuit, Planned Parenthood and ACLU argued that by blocking the abortion provider from the two federal grants — the Personal Responsibility Education Program (PREP) and the Community Adolescent Pregnancy Prevention (CAPP) — the law violated protections of free speech, due process and equal protection.

“The decision recognizes that the law blocking Planned Parenthood from receiving grants to provide this programming violated the constitutional requirement of equal protection,” ACLU of Iowa Legal Director Rita Bettis Austen said in a statement Thursday.

Though Planned Parenthood would be excluded, the law did allow “nonprofit health care delivery systems” to remain eligible for the federal funding, even if they are contracted with or are affiliated with an entity that performs abortions or maintains a facility where abortions are performed.

By doing so, the law effectively singles out Planned Parenthood, but allows other possible grant recipients to provide an array of abortion-related services, according to the court documents.

“The carved-out exception for the ‘nonprofit health care delivery system’ facilities undermines any rationale the State produces of not wanting to be affiliated with or provide funds to organizations that partake in any abortion-related activity,” Scott ruled. .

In fiscal year 2019, Planned Parenthood received about $265,000 through the federal grants, including $85,000 to offer PREP curriculum in Polk, Pottawattamie and Woodbury counties.

It was awarded $182,000 this year to offer CAPP curriculum in Linn County, as well as in Dallas, Des Moines, Jasper, Lee, Polk, Plymouth and Woodbury counties.

The grants are administered by the Iowa Department of Human Services and the Iowa Department of Public Health.

Planned Parenthood has provided sex education to students in 31 schools and 12 community-based youth organizations in Iowa using state-approved curriculum since 2005, according to a new release.

The focus has remained “on areas with the highest rates of unintended pregnancies and sexually-transmitted infections,” the news release said.

“Today’s decision ensures that teens and young adults across Iowa will continue to have access to medically accurate sex education programs, despite the narrow and reckless policies of anti-abortion lawmakers,” said Erin Davison-Rippey, executive director of Planned Parenthood North Central States.

We compute non-extremal three-point functions of scalar operators in $mathcal{N}=4$ super Yang-Mills at tree-level in $g_{YM}$ and at finite $N_c$, using the operator basis of the restricted Schur characters. We make use of the diagrammatic methods called quiver calculus to simplify the three-point functions. The results involve an invariant product of the generalized Racah-Wigner tensors ($6j$ symbols). Assuming that the invariant product is written by the Littlewood-Richardson coefficients, we show that the non-extremal three-point functions satisfy the large $N_c$ background independence; correspondence between the string excitations on $AdS_5 imes S^5$ and those in the LLM geometry.

Willems et al.'s fundamental lemma asserts that all trajectories of a linear system can be obtained from a single given one, assuming that a persistency of excitation condition holds. This result has profound implications for system identification and data-driven control, and has seen a revival over the last few years. The purpose of this paper is to extend Willems' lemma to the situation where multiple (possibly short) system trajectories are given instead of a single long one. To this end, we introduce a notion of collective persistency of excitation. We will then show that all trajectories of a linear system can be obtained from a given finite number of trajectories, as long as these are collectively persistently exciting. We will demonstrate that this result enables the identification of linear systems from data sets with missing data samples. Additionally, we show that the result is of practical significance in data-driven control of unstable systems.

This work has been motivated by recent papers that quantify the density of values of generic quadratic forms and other polynomials at integer points, in particular ones that use Rogers' second moment estimates. In this paper we establish such results in a very general framework. Namely, given any subhomogeneous function (a notion to be defined) $f: mathbb{R}^n o mathbb{R}$, we derive a necessary and sufficient condition on the approximating function $psi$ for guaranteeing that a generic element $fcirc g$ in the $G$-orbit of $f$ is $psi$-approximable; that is, $|fcirc g(mathbf{v})| le psi(|mathbf{v}|)$ for infinitely many $mathbf{v} in mathbb{Z}^n$. We also deduce a sufficient condition in the case of uniform approximation. Here, $G$ can be any closed subgroup of $operatorname{ASL}_n(mathbb{R})$ satisfying certain axioms that allow for the use of Rogers-type estimates.

We deal with various Diophantine equations involving the Euler totient function and various sequences of numbers, including factorials, powers, and Fibonacci sequences.

This work presents a novel data-driven framework for constructing eigenfunctions of the Koopman operator geared toward prediction and control. The method leverages the richness of the spectrum of the Koopman operator away from attractors to construct a rich set of eigenfunctions such that the state (or any other observable quantity of interest) is in the span of these eigenfunctions and hence predictable in a linear fashion. The eigenfunction construction is optimization-based with no dictionary selection required. Once a predictor for the uncontrolled part of the system is obtained in this way, the incorporation of control is done through a multi-step prediction error minimization, carried out by a simple linear least-squares regression. The predictor so obtained is in the form of a linear controlled dynamical system and can be readily applied within the Koopman model predictive control framework of [12] to control nonlinear dynamical systems using linear model predictive control tools. The method is entirely data-driven and based purely on convex optimization, with no reliance on neural networks or other non-convex machine learning tools. The novel eigenfunction construction method is also analyzed theoretically, proving rigorously that the family of eigenfunctions obtained is rich enough to span the space of all continuous functions. In addition, the method is extended to construct generalized eigenfunctions that also give rise Koopman invariant subspaces and hence can be used for linear prediction. Detailed numerical examples with code available online demonstrate the approach, both for prediction and feedback control.

We study a class of fourth order nonlinear parabolic equations which include the thin-film equation and the quantum drift-diffusion model as special cases. We investigate these equations by first developing functional inequalities of the type $ int_Omega u^{2gamma-alpha-eta}Delta u^alphaDelta u^eta dx geq cint_Omega|Delta u^gamma |^2dx $, which seem to be of interest on their own right.

The paper proves the Riemann Hypothesis.

We use the classical Fourier analysis to introduce analytic families of weighted differential operators on the unit sphere. These operators are polynomial functions of the usual Beltrami-Laplace operator. New inversion formulas are obtained for totally geodesic Funk transforms on the sphere and the correpsonding lambda-cosine transforms.

We define local indices for projective umbilics and godrons (also called cusps of Gauss) on generic smooth surfaces in projective 3-space. By means of these indices, we provide formulas that relate the algebraic numbers of those characteristic points on a surface (and on domains of the surface) with the Euler characteristic of that surface (resp. of those domains). These relations determine the possible coexistences of projective umbilics and godrons on the surface. Our study is based on a "fundamental cubic form" for which we provide a closed simple expression.

In this paper we study removable singularities for regular $(1,1/2)$-Lipschitz solutions of the heat equation in time varying domains. We introduce an associated Lipschitz caloric capacity and we study its metric and geometric properties and the connection with the $L^2$ boundedness of the singular integral whose kernel is given by the gradient of the fundamental solution of the heat equation.

A natural problem in the context of the coupon collector's problem is the behavior of the maximum of independent geometrically distributed random variables (with distinct parameters). This question has been addressed by Brennan et al. (British J. of Math. & CS. 8 (2015), 330-336). Here we provide explicit asymptotic expressions for the moments of that maximum, as well as of the maximum of exponential random variables with corresponding parameters. We also deal with the probability of each of the variables being the maximal one.

The calculations lead to expressions involving Hurwitz's zeta function at certain special points. We find here explicitly the values of the function at these points. Also, the distribution function of the maximum we deal with is closely related to the generating function of the partition function. Thus, our results (and proofs) rely on classical results pertaining to the partition function.

We construct a 2-equivalence $mathfrak{CohTheory}^ ext{op} simeq mathfrak{TypeSpaceFunc}$. Here $mathfrak{CohTheory}$ is the 2-category of positive theories and $mathfrak{TypeSpaceFunc}$ is the 2-category of type space functors. We give a precise definition of interpretations for positive logic, which will be the 1-cells in $mathfrak{CohTheory}$. The 2-cells are definable homomorphisms. The 2-equivalence restricts to a duality of categories, making precise the philosophy that a theory is `the same' as the collection of its type spaces (i.e. its type space functor).

In characterising those functors that arise as type space functors, we find that they are specific instances of (coherent) hyperdoctrines. This connects two different schools of thought on the logical structure of a theory.

The key ingredient, the Deligne completeness theorem, arises from topos theory, where positive theories have been studied under the name of coherent theories.

In the spirit of very recent articles by J. Bonet, W. Lusky and J. Taskinen we are studying the so-called solid hulls and cores of spaces of weighted entire functions when the weights are given in terms of associated weight functions coming from weight sequences. These sequences are required to satisfy certain (standard) growth and regularity properties which are frequently arising and used in the theory of ultradifferentiable and ultraholomorphic function classes (where also the associated weight function plays a prominent role). Thanks to this additional information we are able to see which growth behavior the so-called "Lusky-numbers", arising in the representations of the solid hulls and cores, have to satisfy resp. if such numbers can exist.

We establish the functional convex order results for two scaled McKean-Vlasov processes $X=(X_{t})_{tin[0, T]}$ and $Y=(Y_{t})_{tin[0, T]}$ defined by

[egin{cases} dX_{t}=(alpha X_{t}+eta)dt+sigma(t, X_{t}, mu_{t})dB_{t}, quad X_{0}in L^{p}(mathbb{P}),\ dY_{t}=(alpha Y_{t},+eta)dt+ heta(t, Y_{t}, u_{t})dB_{t}, quad Y_{0}in L^{p}(mathbb{P}). end{cases}] If we make the convexity and monotony assumption (only) on $sigma$ and if $sigmaleq heta$ with respect to the partial matrix order, the convex order for the initial random variable $X_0 leq Y_0$ can be propagated to the whole path of process $X$ and $Y$. That is, if we consider a convex functional $F$ with polynomial growth defined on the path space, we have $mathbb{E}F(X)leqmathbb{E}F(Y)$; for a convex functional $G$ defined on the product space involving the path space and its marginal distribution space, we have $mathbb{E},Gig(X, (mu_t)_{tin[0, T]}ig)leq mathbb{E},Gig(Y, ( u_t)_{tin[0, T]}ig)$ under appropriate conditions. The symmetric setting is also valid, that is, if $ heta leq sigma$ and $Y_0 leq X_0$ with respect to the convex order, then $mathbb{E},F(Y) leq mathbb{E},F(X)$ and $mathbb{E},Gig(Y, ( u_t)_{tin[0, T]}ig)leq mathbb{E},G(X, (mu_t)_{tin[0, T]})$. The proof is based on several forward and backward dynamic programming and the convergence of the Euler scheme of the McKean-Vlasov equation.

We establish versions of Conley's (i) fundamental theorem and (ii) decomposition theorem for a broad class of hybrid dynamical systems. The hybrid version of (i) asserts that a globally-defined "hybrid complete Lyapunov function" exists for every hybrid system in this class. Motivated by mechanics and control settings where physical or engineered events cause abrupt changes in a system's governing dynamics, our results apply to a large class of Lagrangian hybrid systems (with impacts) studied extensively in the robotics literature. Viewed formally, these results generalize those of Conley and Franks for continuous-time and discrete-time dynamical systems, respectively, on metric spaces. However, we furnish specific examples illustrating how our statement of sufficient conditions represents merely an early step in the longer project of establishing what formal assumptions can and cannot endow hybrid systems models with the topologically well characterized partitions of limit behavior that make Conley's theory so valuable in those classical settings.

We study how to infer new choices from previous choices in a conservative manner. To make such inferences, we use the theory of choice functions: a unifying mathematical framework for conservative decision making that allows one to impose axioms directly on the represented decisions. We here adopt the coherence axioms of De Bock and De Cooman (2019). We show how to naturally extend any given choice assessment to such a coherent choice function, whenever possible, and use this natural extension to make new choices. We present a practical algorithm to compute this natural extension and provide several methods that can be used to improve its scalability.

Lambda functions are quite an intuitive concept of Modern C++ introduced in C++11, so there are already tons of articles on lambda function tutorials over the internet. But still, there are some untold things (like IIFE, types of lambda, etc.) left, which nobody talks about. Therefore, here I am to not only show you lambda function in C++, but we'll also cover how it works internally and other aspects of Lambda.

The title of this article is a bit misleading. Because lambda doesn't always synthesize to function pointer. It's an expression (precisely unique closure). But I have kept it that way for simplicity. So from now on, I will use lambda function and expression interchangeably.
