It’s time to pay the true value of tropical forest conservation (commentary)
Tropical forests help regulate the global climate, host irreplaceable biodiversity and provide fresh water resources. Plus forests in general are the source of livelihoods for more than a billion people — so our very existence depends on them. However, because their value is not reflected in markets, these areas are often converted to other uses. Conserving our tropical forests […]

Building Forest Inventories with Autonomous Legged Robots -- System, Lessons, and Challenges Ahead
Legged robots are increasingly being adopted in industries such as oil, gas, mining, nuclear, and agriculture. However, new challenges exist when moving into natural, less-structured environments, such as forestry applications. This paper presents a prototype system for autonomous, under-canopy forest inventory with legged platforms. Motivated by the robustness and mobility of modern legged robots, we introduce a system architecture which enabled a quadruped platform to autonomously navigate an…

Generalizable estimation of conditional average treatment effects using Causal Forest in randomized
Generalizing conditional average treatment effects (CATE) estimates in a randomized controlled trial (RCT) to a broader source population can be challenging because of selection bias and high-dimensional covariates. We aim to evaluate CATE estimation approaches using Causal Forest that address selection bias due to trial participation. We propose and compare four CATE estimation approaches using Causal Forest: (1) ignoring selection variables, (2) including selection variables, (3) using invers…

Random walk reflected off of infinity, with applications to uniform spanning forests and supercritical Liouville quantum gravity
Let $\mathcal G$ be an infinite graph -- not necessarily one-ended -- on which the simple random walk is transient. We define a variant of the continuous-time random walk on $\mathcal G$ which reaches $\infty$ in finite time and "reflects off of $\infty$" infinitely many times. We show that the Aldous-Broder algorithm for the random walk reflected off of $\infty$ gives the free uniform spanning forest (FUSF) on $\mathcal G$. Furthermore, Wilson's algorithm for the random walk reflected off of…

While the models depend most importantly on the bias parameters of the intergalactic medium (IGM), they also depend on the numbers and characteristics of high-column-density systems (HCD…

Empirical Models of the Time Evolution of SPX Option Prices
The key objective of this paper is to develop an empirical model for pricing SPX options that can be simulated over future paths of the SPX. To accomplish this, we formulate and rigorously evaluate several statistical models, including neural network, random forest, and linear regression. These models use the observed characteristics of the options as inputs -- their price, moneyness and time-to-maturity, as well as a small set of external inputs, such as the SPX and its past history, dividend …

Decadal sink-source shifts of forest aboveground carbon since 1988
As enduring carbon sinks, forest ecosystems are vital to the terrestrial carbon cycle and help moderate global warming. However, the long-term dynamics of aboveground carbon (AGC) in forests and their sink-source transitions remain highly uncertain, owing to changing disturbance regimes and inconsistencies in observations, data processing, and analysis methods. Here, we derive reliable, harmonized AGC stocks and fluxes in global forests from 1988 to 2021 at high spatial resolution by integratin…

We define the HOMFLY polynomial of a forest quiver $Q$ using a recursive definition on the underlying graph of the quiver. We then show that this polynomial is equal to the HOMFLY polynomial of any plabic link which comes from a connected plabic graph whose quiver is $Q$. We also prove a closed-form expression for the HOMFLY polynomial of a forest quiver $Q$ in terms of the independent sets of $Q$.

Hamilton cycles in tough $(2P_2 \cup P_1)$-free graphs
In 1973, Chvátal conjectured that there exists a constant $t_0$ such that every $t_0$-tough graph on at least three vertices is Hamiltonian. While this conjecture is still open, work has been done to confirm it for several graph classes, including all $F$-free graphs for every 5-vertex linear forest $F$ other than $P_5$ and $2P_2\cup P_1$. In this note, we show that 11-tough $(2P_2 \cup P_1)$-free graphs on at least three vertices are Hamiltonian.

I wasn't able to process the photos of my recent trips, but I wanted to share this one from last year.
I went there on a hot day to "take a couple of photos". In the end I spent 3h just at this waterfall searching for the right composition & interpretation, the right motive etc.
I love the result, but I'm surprised how much time I spent there to get it.

On feature selection in double-imbalanced data settings: a Random Forest approach
Feature selection is a critical step in high-dimensional classification tasks, particularly under challenging conditions of double imbalance, namely settings characterized by both class imbalance in the response variable and dimensional asymmetry in the data $(n \gg p)$. In such scenarios, traditional feature selection methods applied to Random Forests (RF) often yield unstable or misleading importance rankings. This paper proposes a novel thresholding scheme for feature selection based on mini…

Critically endangered chameleon discovered outside its known habitat in Madagascar
ANTANANARIVO — At the end of April, a team of researchers scouring a scarred area of spiny forest in southwestern Madagascar came across three individuals of a critically endangered chameleon species. Furcifer belalandaensis had not previously been recorded outside of a tiny, 4-square-kilometer (1.5-square-mile) area near the village of Belalanda after which it’s named, so […]

Hi friends!
I set my alarm to 5am and headed out for a nice walk. It was getting warm, so I started early. - and it was just so good to do so!
A nice 6h walk with lots of views, lots of photos and just enjoying being out. End the #summit just for me 😍
On the way up I noted all places where I could refuel later using my water filter. Seriously: why didn't I buy that waaays ear…

Contributions to conjectures in planar graphs: Induced Substructures, Treewidth, and Dominating Sets
Two of the most prominent unresolved conjectures in graph theory, the Albertson-Berman conjecture and the Matheson-Tarjan conjecture, have been extensively studied by many researchers. (AB) Every planar graph of order $n$ has an induced forest of order at least $\frac{n}{2}$. (MT) Every plane triangulation of sufficiently large order $n$ has a dominating set of cardinality at most $\frac{n}{4}$. Although partial results and weaker bounds than those originally conjectured have been obtaine…

Automatic Doubly Robust Forests
This paper proposes the automatic Doubly Robust Random Forest (DRRF) algorithm for estimating the conditional expectation of a moment functional in the presence of high-dimensional nuisance functions. DRRF extends the automatic debiasing framework based on the Riesz representer to the conditional setting and enables nonparametric, forest-based estimation (Athey et al., 2019; Oprescu et al., 2019). In contrast to existing methods, DRRF does not require prior knowledge of the form of the debiasin…

Africa has the highest rate of forest loss in the world—what the G20 can do about it
Africa needs its forests for sustainable development, poverty reduction, food security, and to make the continent more resilient to climate change. They take up 23% of the continent. At 674 million hectares in extent, these forests occupy an area the same size as the Amazon rainforest.

Unified reconstruction of the Lyman-alpha power spectrum with Hamiltonian Monte Carlo
The complex geometry of the Ly$α$ forest data has motivated the use of various two-point statistics as alternatives to the three-dimensional power spectrum ($P_{\mathrm{3D}}$), which carries cosmological information in Fourier space. On large scales, the three-dimensional correlation function ($ξ_\mathrm{3D}$) has provided robust measurements of the baryon acoustic oscillation (BAO) scale at 150 Mpc. On smaller scales, the one-dimensional power spectrum, $P_{\mathrm{1D}}(k_\|)$, has been…

Armed groups, cattle ranchers drove 35% rise in Colombia’s deforestation in 2024
The prediction came true: deforestation in Colombia increased in 2024 after two years of decline, just as the environment ministry had warned since April last year. The ministry announced that Colombia lost 1,070 square kilometers (413 square miles) of forest in 2024, a 35% increase from 2023, when deforestation hit 793 km2 (306 mi2). Former […]

Forests for Differences: Robust Causal Inference Beyond Parametric DiD
This paper introduces the Difference-in-Differences Bayesian Causal Forest (DiD-BCF), a novel non-parametric model addressing key challenges in DiD estimation, such as staggered adoption and heterogeneous treatment effects. DiD-BCF provides a unified framework for estimating Average (ATE), Group-Average (GATE), and Conditional Average Treatment Effects (CATE). A core innovation, its Parallel Trends Assumption (PTA)-based reparameterization, enhances estimation accuracy and stability in complex …
