Defect‐Engineered Nested Metallic Cu Clusters Enhance CO2 Photoreduction in Photothermal 2D Plasmonic CuSe

open access: yesEcoEnergy, EarlyView.
Solar‐driven photocatalytic CO2 conversion faces charge dynamics and spectral utilization limits. In this study, the nested Cu/CuSe heterostructure effectively enhances near‐infrared absorption, suppress charge carrier recombination, and improve CO production yield and selectivity through the photothermal–photocatalytic synergy. ABSTRACT Photocatalytic

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Megachile (Megachile) montivaga (Hymenoptera: Megachilidae) nesting in live thistle (Asteraceae: Cirsium) [PDF]

open access: yes, 2015
Although Megachile Latreille (leafcutter bees) are well known for their diverse nesting habits, records of the genus nesting in live plants are rare.  Here, we report the widespread Megachile (Megachile) montivaga Cresson nesting in live thistle (Cirsium

Behavioral and epileptic phenotypes in a CHD2‐related developmental delay model

open access: yesEpilepsia, EarlyView.
Abstract Objective Heterozygous loss‐of‐function mutations in the CHD2 gene, encoding chromodomain helicase DNA‐binding protein 2, are associated with severe childhood onset epilepsy, global developmental delay, and autistic features. Animal models that accurately recapitulate human phenotypes are crucial for understanding rare neurodevelopmental ...

Pollinating insect responses to grazing intensity, grassland characteristics and landscape complexity [PDF]

open access: yes, 2007
Pollinators uphold important ecological functions and their economic and ecological importance is considerable. In the present thesis the relationship between management practices and the behaviour, diversity and composition of four flower visitor groups:

ECOLOGY OF CRABRONID WASPS FOUND IN TRAP NESTS FROM SPAIN (HYMENOPTERA: SPHECIFORMES)

open access: yesFlorida Entomologist, 2005
We report data obtained concerning the occupation of trap nests by xylicolous Crabronidae (sensu Melo 1999) in a study carried out in central Spain between 1992 and 1995. In particular, we analyze the data on the occupation of the nests for Psenulus concolor (Dahlbom), Trypoxylon attenuatum F. Smith, and Trypoxylon beaumonti Antropov. All three species

Probabilistic Multi‐Objective Energy Management System Model for an Energy Hub With PtG Technology for Cost Reduction and System Flexibility Improvement

open access: yesEnergy Science &Engineering, EarlyView.
Overview of the under‐study hub energy model showing the energy conversion and distribution among integrated sources and loads. ABSTRACT In this paper, a probabilistic bi‐objective energy management system (EMS) model is proposed for an energy hub (EH) equipped with renewable energy sources such as photovoltaic and wind turbine connected to the main ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

open access: yesEnergy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Deceptive Thyroid Pathologies: Anaplastic Thyroid Carcinoma Mimics and Clinical Implications

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Beyond follicular‐derived thyroid carcinomas, lymphomas, and metastatic disease, there are rare pathologies of the thyroid gland that represent a challenge. We report patients with unusual malignancies that mimic similar aggressive cancers. Methods Retrospective case series.
