Análisis cuantitativo de la investigación en invasiones biológicas en Chile: tendencias y desafíos Quantitative analysis of the research in biological invasions in Chile: Trends and challenges

open access: yesRevista Chilena de Historia Natural, 2009
En las últimas dos décadas, el estudio de las invasiones biológicas ha alcanzado un auge sin precedentes a nivel mundial tanto en sus dimensiones teóricas como aplicadas. En Chile, las invasiones biológicas parecieran ser un tema relativamente nuevo.

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

open access: yesAdvanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

The dynamical diquark model: first numerical results

open access: yesJournal of High Energy Physics, 2019
We produce the first numerical predictions of the dynamical diquark model of multiquark exotic hadrons. Using Born-Oppenheimer potentials calculated numerically on the lattice, we solve coupled and uncoupled systems of Schrödinger equations to obtain ...

Search for excited τ-leptons and leptoquarks in the final state with τ-leptons and jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search is reported for excited τ-leptons and leptoquarks in events with two hadronically decaying τ-leptons and two or more jets. The search uses proton-proton (pp) collision data at s $$ \sqrt{s} $$ = 13 TeV recorded by the ATLAS experiment during the

Exotic Mammals Disperse Exotic Fungi That Promote Invasion by Exotic Trees

open access: yesPLoS ONE, 2013
غالبًا ما تكون الغزوات البيولوجية ظواهر معقدة لأن العديد من العوامل تؤثر على نتائجها. يتمثل أحد الجوانب الرئيسية في كيفية تفاعل غير المواطنين مع الكائنات الحية المحلية. قد يكون التفاعل مع الأنواع المحلية مهمًا بشكل خاص للأنواع الغريبة التي تتطلب تبادليًا إلزاميًا، مثل أنواع الصنوبرية التي تحتاج إلى الفطريات الظاهرية الجذرية (EM).

Proximity Induced Magnetic Anisotropy and Trefoil Fermiology in Monolayer FeCl2/Bi(111)

open access: yesAdvanced Materials, EarlyView.
Reorientation of magnetic anisotropy in a 2D van der Waals magnet is demonstrated in monolayer FeCl2 epitaxially grown on a bismuth substrate, from its natural out‐of‐plane direction to a predominantly in‐plane orientation. The FeCl2/bismuth heterostructure exhibits moiré‐induced interface states, suggesting strong coupling at the interface.

The impact of the transgenic revolution on aquaculture and biodiversity. A review

open access: yesRevista Científica, 2010
We discuss the aims and techniques of transgenics and examine some consequences of incorporating genetic modified organisms (GMs) into the aquaculture industry, as well as introducing them into native habitats. The detrimental effects of introducing

Search for pair-produced scalar and vector leptoquarks decaying into third-generation quarks and first- or second-generation leptons in pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for pair-produced scalar and vector leptoquarks decaying into quarks and leptons of different generations is presented. It uses the full LHC Run 2 (2015–2018) data set of 139 fb −1 collected with the ATLAS detector in proton–proton collisions at

Current Switching of Topological Spin Chirality in the van der Waals Antiferromagnet Co1/3TaS2

open access: yesAdvanced Materials, EarlyView.
Spin chirality plays a central role in quantum magnetism, governing spin winding and generating real‐space Berry phases. We propose the intriguing concept of current‐switching spin chirality and demonstrate it via unconventional intrinsic self‐spin‐orbit‐torque in pristine Co1/3TaS2, purely by electrical current and with high energy efficiency.

New Approaches to Ecologically Based, Designed Urban Plant Communities in Britain: Do These Have Any Relevance in the United States?

open access: yesCities and the Environment, 2008
This paper discusses the reasoning behind the development of a new approach to designed urban planting with grasses, forbs and geophytes that has been undertaken at the University of Sheffield over the past 15 years.
