Summary: This study evaluated the habitat and abundance of Japanese Spanish mackerel in the Yellow Sea, East China Sea, and Sea of Japan using a generalized additive model and generalized linear model on catch per unit effort (CPUE) data from Japanese purse-seine vessels. The results showed that Japanese Spanish mackerel prefer regions of low temperature at 10 m depth, with a high CPUE area observed in the Yellow and East China seas from 1994 to 1997. The CPUE values increased until 2000, with fluctuations thereafter and stability after 2010. It is the first stock assessment report based on the Japanese large and mid-sized purse seine fishery in the region, suggesting further collaboration with China and Korea for accurate stock assessment and management of the species.

Summary: Deep learning has been used for mapping periglacial landforms, but its application is limited to local areas. Through experiments, it is found that data augmentation improves accuracy but does not guarantee transferability, choosing appropriate hyperparameter combinations can balance accuracy and efficiency, and generative adversarial networks significantly improve transferability.

Summary: We discuss the impact of misspecification and censoring on Bayesian model selection in the context of right-censored survival and concave log-likelihood regression. Misspecification includes wrongly assuming that the censoring mechanism is noninformative. We focus on additive accelerated failure time, Cox proportional hazards, and probit models. We provide a theoretical treatment that incorporates local and nonlocal priors, as well as a general nonlinear effect decomposition for improved power-sparsity trade-offs.

Summary: The generalized linear mixed model (GLMM) is a common method for analyzing longitudinal and clustered data in biological sciences. However, issues of model complexity and misspecification can arise. This paper extends the standard GLMM to a nonlinear mixed-effects model based on quasi-linear modeling, providing an estimation algorithm and a conditional AIC for the proposed model. Performance under model misspecification is evaluated in simulation studies, and the proposed model is shown to capture heterogeneity in respiratory illness data.

Summary: Multiple studies have shown that narrow-linear strong disturbances caused by pipeline engineering activities can lead to rapid permafrost degradation. However, there is still uncertainty about the extent and severity of permafrost disturbances induced by two parallel buried warm-oil pipelines. This study examines the thermal disturbances caused by the China-Russia crude oil pipelines on the surrounding permafrost. The findings suggest that the warm oil flow in the pipelines dissipates heat to the surrounding soil, resulting in thawing of the permafrost and the formation of thaw bulbs around the pipes.

Summary: Ordinary differential equations (ODEs) are commonly used in real applications to describe the dynamics of complex systems. In this article, we propose a novel joint estimation approach for generalized sparse additive ODEs, allowing for non-Gaussian observations. The method considers likelihood, ODE fidelity, and sparse regularization simultaneously, and is optimized using a block coordinate descent algorithm for non-convex and non-differentiable objective functions. The global convergence of the algorithm is established, and simulation studies and two applications demonstrate the superior performance of the method in estimation and identifying sparse structures.

Summary: Urban tree cover is considered an environmentally-friendly and effective approach for urban cooling, but its effectiveness is influenced by meteorological variables and varies in cities with different climates. African cities, especially arid ones, should not rely solely on increasing tree cover to alleviate heat stress, but instead consider other combined cooling strategies.

Summary: Small glaciers in temperate mountain regions have experienced significant reduction and unprecedented melt rates in recent years. Some glaciers have transitioned from clean ice to debris-covered or even rock glaciers. This study examines the surface elevation change of the Popera Alto glacier in the Sesto Dolomites using LiDAR and Structure from Motion surveys, and analyzes its evolution in terms of surface cover and geomorphic processes. The glacier has lost an average of 0.35 m water equivalent per year over the past 16 years, with active modification of its surface cover by geomorphic processes. The role of debris and local topography feedback has allowed the resilience of the glacier, leading to a marked difference between the current environmental equilibrium line altitude (envELA) and the effective ELA (effELA) of the glacier.

Summary: The study investigates the relationship between glacial dynamics and lake sedimentation during the mid-Holocene climate variability in the Southern Zanskar ranges. It utilizes geomorphological disposition, elemental geochemistry, and optical chronology of relict lake sediment to reconstruct the pattern of minor glacier responses to climate variability. The results indicate six centennial to millennial-scale climatic phases, with warmer phases represented by decreased mineralogical fine grain flux and increased coarse grain flux. The study highlights the potential of relict lake sediment and para/peri-glacial landforms in understanding glacial dynamics and climate change during the Holocene.
