The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)
The Anatomical Record, EarlyView.Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

New methods to reduce leakage errors in planar near-field measurements [PDF]
, 2011 This paper describes two methods to cancel the effect of two kinds of leakage signals which may be presented when an antenna is measured in a planar near-field range.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Cosecant-beam horn array antenna.
The Journal of the Institute of Television Engineers of Japan, 1988 幾何光学に基づいて設計したE面コセカントビームホーンを素子アンテナとして用いた1次配列アレイアンテナを構成し, このアレイ化によって, サービスエリア内の電力分布の差はほぼ±3dB以内におさえた.またサービスエリア外では, サービスエリアの辺縁部から約-3dB/1°方位角の割合で電力が弱まっていくなどの特性を持つ, 質の良いSHF小規模放送用コセカントビームアレイアンテナを実験で確認した.本論文は, このアレイアンテナの設計法, 指向性計算および試作したアンテナの実験結果について述べる.

Anatomical Sciences Education, EarlyView.Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Molecular bases of insect odorant receptor function: specificity and evolution
Biological Reviews, EarlyView.ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Business Strategy and the Environment, EarlyView.ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...
