A Novel Form of Stereo Vision in the Praying Mantis [PDF]

Current Biology, 2018
Stereopsis is the ability to estimate distance based on the different views seen in the two eyes [1-5]. It is an important model perceptual system in neuroscience and a major area of machine vision. Mammalian, avian, and almost all machine stereo algorithms look for similarities between the luminance-defined images in the two eyes, using a series of ...

Application of Neural Networks for Advanced Ir Spectroscopy Characterization of Ceria Catalysts Surfaces

Advanced Intelligent Discovery, EarlyView.
A novel convolutional neural network architecture enables rapid, unsupervised analysis of IR spectroscopic data from DRIFTS and IRRAS. By combining synthetic data generation with parallel convolutional layers and advanced regularization, the model accurately resolves spectral features of adsorbed CO, offering real‐time insights into ceria surface ...

The hindgut microbiota of praying mantids is highly variable and includes both prey-associated and host-specific microbes.

PLoS ONE, 2018
Praying mantids are predators that consume a wide variety of insects. While the gut microbiome of carnivorous mammals is distinct from that of omnivores and herbivores, the role of the gut microbiome among predatory insects is relatively understudied ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

An Artificial Synaptic Plasticity Mechanism for Classical Conditioning with Neural Networks [PDF]

, 2014
We present an artificial synaptic plasticity (ASP) mechanism that allows artificial systems to make associations between environmental stimuli and learn new skills at runtime. ASP builds on the classical neural network for simulating associative learning,

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

Macromolecular Rapid Communications, EarlyView.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...

Ionothermal Synthesis of Cu(Sb2Se3)[AlCl4] and Cu5(Bi2Se3)6[AlCl4]5 : Monolayers of Sb2Se3 and Bi2Se3 Stabilized by Cu[AlCl4]

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Ionothermal synthesis in Lewis‐acidic ionic liquids (ILs) yields two new low‐dimensional pnictogen–selenide networks cocrystallized with Cu[AlCl4]. Both are narrow‐gap semiconductors that exhibit strong absorption throughout the visible range. Topochemical AlCl3 extraction triggers partial delamination, pointing to a viable route toward 2D derivatives.

Review of the genera Glabromantis, Paraoxypilus and Phthersigena (Mantodea: Nanomantidae: Fulciniinae)

Records of the Australian Museum
Three genera of the mantis subfamily Fulciniinae (Mantodea: Nanomantidae: Fuliciniinae) are revised. In the genus Glabromantis two species are recognized, in Paraoxypilus five species and in Phthersigena one species is recognized. The genus Myrmecomantis
