Organic Photo‐Responsive Piezoelectric Materials Based on Pyrene Molecules for Flexible Sensors

open access: yesAdvanced Electronic Materials, Volume 11, Issue 11, July 2025.
An organic, pyrene‐based non‐centrosymmetric crystal, PyPT, is introduced, showcasing excellent piezoelectric behavior with a high‐output electrical signal, rapid response time, and a substantial piezoelectric coefficient. The piezoelectric sensors demonstrate the ability to recognize physical sound characteristics ‐ such as amplitude, frequency, and ...

Enhanced Triboelectric Performance of Degradable Polylactic Acid Nanocomposite Thin Films

open access: yesChemNanoMat, Volume 11, Issue 5, May 2025.
Nanocomposite films derived from polylactic acid (PLA) are developed utilizing Co‐, Mn‐, and Ni‐doped Fe2O3 nanoparticles through solution casting. Comprehensive structural, thermal, and morphological assessments validate the enhancement in crystallinity and surface roughness.

The biocultural heritage and changing role of indigenous yams in the Republic of Guinea, West Africa

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 719-733, May 2025.
Global yam production is centred on West Africa, but there are significant knowledge gaps about farm‐level diversity across much of the region, and especially in Guinea. Although yam production is increasing in Guinea, in the longer term, varietal diversity and the sustainability of agri‐systems are at risk.

Fluctuating Glasma initial conditions and flow in heavy ion collisions

open access: yes, 2012
We compute initial conditions in heavy-ion collisions within the Color Glass Condensate (CGC) framework by combining the impact parameter dependent saturation model (IP-Sat) with the classical Yang-Mills description of initial Glasma fields.

Training‐Augmented Ionic Switch for Logic Signal Modulation

open access: yesAdvanced Electronic Materials, Volume 11, Issue 3, March 2025.
A reversible phase‐transition hydrated salt crystal ion switch gel is developed, featuring a trainable enhanced ion switch ratio. By controlling the phase transition process and training cycles of the ion gel, the device exhibits excellent signal modulation, signal amplification, and information latch functions and further demonstrates its versatility ...

We must know. We will know

open access: yes, 2010
The after-dinner talk has by now become a tradition of this Conference series on Quark Confinement and the Hadron Spectrum. On this occasion, I have tried to combine a free-style and (hopefully) amusing presentation with deep questions of physics ...

The dawn of division: For an anthropological theory of consciousness through contemplative ethnography

open access: yesAnthropology of Consciousness, Volume 36, Issue 1, Spring 2025.
AbstractThe article delves into the need for an anthropological exploration of consciousness in the modern context. While anthropology's core focus has always been the study of the human subject, this study argues that consciousness has emerged as a fundamental aspect that underpins all human phenomena.

A SVM-Based Multi-Resolution Procedure for the Estimation of the DOAS of Interfering Signals in a Communication System [PDF]

open access: yes, 2011
In this work, the use of a planar antenna system for the estimation of the directions of arrivals (DOAs) of multiple signals impinging on the receiver has been considered.

Lattice for Musical Structures and Its Arithmetics

open access: yesLattice for Musical Structures and Its Arithmetics
提案した音楽理論GTTMに基づいて楽曲全体を木構造として表現する手法を用いると,楽曲間に半順序関係を定義し導入することができ,楽曲を要素とする束 (楽曲構造束) を構成できる.楽曲の木構造を素性構造で表現すると,楽曲間の順序づけやmeet, joinと言った束演算は純粋に数学的なアルゴリズムとして実現可能となる.しかし実用的な場面では以下の3つの課題に直面する:包摂関係, meet, joinだけでは不足する演算の記述力を補うために導入した相対擬補元に関する課題,楽曲 (束上の元) 間の距離の抽象化に関する課題,楽曲間の関係だけでなく,楽曲を修正・加工する操作や手順の形式化に関する課題.本稿では ...
