Opportunities and challenges for Common Agricultural Policy reform to support the European Green Deal

open access: yesConservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract The Common Agricultural Policy (CAP) is the European Union's main instrument for agricultural planning, with a new reform approved for 2023–2027. The CAP intends to align with the European Green Deal (EGD), a set of policy initiatives underpinning sustainable development and climate neutrality in the European Union (EU), but several flaws cast

リアクタンス補償小型合成回路を用いたアウトフェージング増幅器に関する研究 [PDF]

open access: yes, 2021
近年,通信トラフィックの増加を背景に無線通信システムには大容量通信が求められている.大容量無線通信では,ピーク対平均電力比(PAPR)が大きい広帯域デジタル変調信号を使用するため,電力増幅器は広ダイナミックレンジで高効率が得られるものが必要である.しかし,一般的に電力増幅器は飽和レベルでの効率と比較してバックオフ領域では効率が低下する.よって,バックオフ領域の高効率化技術が多く検討されており,アウトフェージング増幅器はその一つである.本報告では,広ダイナミックレンジでの高効率化を図るため ...

Unresolved–Disorganized Attachment is Associated With Smaller Hippocampus and Increased Functional Connectivity Beyond Psychopathology

open access: yesJournal of Traumatic Stress, Volume 32, Issue 5, Page 742-752, October 2019., 2019
Abstract Loss and abuse in children can lead to unresolved–disorganized (UD) attachment. How this condition relates to brain structure and functional connectivity (FC) is unknown. We therefore aimed to investigate gray matter volume (GMV) and resting state functional connectivity (RSFC) correlates of UD attachment in adolescents.

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

open access: yesRare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...
