Brood patch and sex-ratio observations indicate breeding provenance and timing in New Zealand storm petrel (Fregetta maoriana) [PDF]

open access: yes, 2013
We used measurements of brood patch and moult status to estimate the breeding phenology of New Zealand Storm-Petrel, using birds caught at sea within the Hauraki Gulf Marine Park near Auckland, New Zealand.

Mitochondria‐Targeted ROS Scavenging Natural Enzyme Cascade Nanogels for Periodontitis Treatment via Hypoxia Alleviation and Immunomodulation

open access: yesAdvanced Science, EarlyView.
TPP‐SAT, a mitochondria‐targeted natural enzyme‐cascade nanogel, selectively scavenges mitochondrial ROS (e.g., H2O2/·O2⁻) and converts them into therapeutic O2 via enzymatic cascades, alleviating hypoxia and inflammation. It rebalances M1/M2 macrophage polarization, activates the Nrf2 pathway while suppressing NF‐κB, enhances antioxidant defenses, and

The elusive scleral cartilages: Comparative anatomy and development in teleosts and avians

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The sclera of all vertebrate eyes is comprised of connective tissue, with some organisms developing cartilage within this tissue. A review of the cartilages that have been described in the vertebrate sclera and their anatomical relationships is discussed together with their potential homology.

Physiological Response Of Laying Birds To Neem (Azadirachta Indica) Leaf Meal-Based Diets: Body Weight Organ Characteristics And Haematology [PDF]

open access: yes, 2006
A 12-weeks feeding trial was conducted to evaluate the effects of Neem (Azadirachta indica) leafmeal (NLM) on body weight gain, carcass and organ characteristics and haematological values of laying hens.

Graphene/h‐BN/ReS2 Heterostructure Operating in Fowler−Nordheim Tunneling Regime for Polarization‐Sensitive Fast Photodetector

open access: yesAdvanced Electronic Materials, EarlyView.
The authors demonstrate a bias voltage‐dependent anisotropic tunneling behavior by designing a ReS2‐based heterojunction operating in the Fowler–Nordheim tunneling regime. The device exhibits a dichroic tunneling current that surpasses the intrinsic anisotropy of ReS2, offering a new strategy to amplify directional responses in 2D materials for ...

Dopant Diffusion‐Induced Dielectric Breakdown: Stacked Dielectric Reliability on Heavily Doped Polysilicon

open access: yesAdvanced Electronic Materials, EarlyView.
This study reveals a novel failure mode in SiO₂/Si₃N₄ stacked capacitors, where dopant diffusion leads to interfacial oxide thinning, reducing dielectric breakdown voltage. Experimental results show that n type capacitors exhibit superior reliability, whereas p type capacitors fail rapidly.

Bi2O2Se/Ta2NiSe5 Tunneling Heterojunction for High‐Performance, Polarization‐Sensitive, and Broadband Infrared Photodetector

open access: yesAdvanced Electronic Materials, EarlyView.
An optimal dynamic balance between carrier lifetime and transit time is achieved in the Bi2O2Se/Ta2NiSe5 tunneling heterojunction, which simultaneously attains high responsivity (>103 A W−1) and a fast response time (≈5 µs). The specific detectivity can reach 3.75 × 1013 Jones at 633 nm and 1.8 × 1010 Jones at 1550 nm. Abstract New technologies such as

The impact of HPAI trade restrictions on U.S. poultry exports in 2022–23

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract In early 2022, APHIS confirmed a case of highly pathogenic avian influenza (HPAI), signaling the beginning of an extensive HPAI outbreak. Since the start of the outbreak in 2022, more than 105 million birds across commercial and backyard operations in 48 states have been affected. Many countries, including top importers of U.S.

Stringency and dissimilarity of Maximum Residue Levels affect bilateral agri‐food trade stability

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Food standards are rising in both prevalence and stringency. They protect consumers and may enhance demand stability but also pose compliance challenges to producers, with ambiguous effects on the stability of trade relationships. We analyze the impact of importers' Maximum Residue Levels (MRLs) along with bilateral MRL dissimilarity between ...
