A Global Database for Metacommunity Ecology, Integrating Species, Traits
www.nature.com/scientificdata There are amendments to this paper OPEN A global database for DATA DescRIPTOR metacommunity ecology, integrating species, traits, environment and space Alienor Jeliazkov et al.# The use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear how generalizable these relationships are across ecosystems, taxa and spatial scales. To address this gap, we collated 80 datasets from trait-based studies into a global database for metaCommunity Ecology: Species, Traits, Environment and Space; “CESTES”. Each dataset includes four matrices: species community abundances or presences/absences across multiple sites, species trait information, environmental variables and spatial coordinates of the sampling sites. The CESTES database is a live database: it will be maintained and expanded in the future as new datasets become available. By its harmonized structure, and the diversity of ecosystem types, taxonomic groups, and spatial scales it covers, the CESTES database provides an important opportunity for synthetic trait-based research in community ecology. Background & Summary A major challenge in ecology is to understand the processes underlying community assembly and biodiversity patterns across space1,2. Over the three last decades, trait-based research, by taking up this challenge, has drawn increasing interest3, in particular with the aim of predicting biodiversity response to environment. In community ecology, it has been equated to the ‘Holy Grail’ that would allow ecologists to approach the potential processes underlying metacommunity patterns4–7. -

SVP's Letter to Editors of Journals and Publishers on Burmese Amber And
Society of Vertebrate Paleontology 7918 Jones Branch Drive, Suite 300 McLean, VA 22102 USA Phone: (301) 634-7024 Email: [email protected] Web: www.vertpaleo.org FEIN: 06-0906643 April 21, 2020 Subject: Fossils from conflict zones and reproducibility of fossil-based scientific data Dear Editors, We are writing you today to promote the awareness of a couple of troubling matters in our scientific discipline, paleontology, because we value your professional academic publication as an important ‘gatekeeper’ to set high ethical standards in our scientific field. We represent the Society of Vertebrate Paleontology (SVP: http://vertpaleo.org/), a non-profit international scientific organization with over 2,000 researchers, educators, students, and enthusiasts, to advance the science of vertebrate palaeontology and to support and encourage the discovery, preservation, and protection of vertebrate fossils, fossil sites, and their geological and paleontological contexts. The first troubling matter concerns situations surrounding fossils in and from conflict zones. One particularly alarming example is with the so-called ‘Burmese amber’ that contains exquisitely well-preserved fossils trapped in 100-million-year-old (Cretaceous) tree sap from Myanmar. They include insects and plants, as well as various vertebrates such as lizards, snakes, birds, and dinosaurs, which have provided a wealth of biological information about the ‘dinosaur-era’ terrestrial ecosystem. Yet, the scientific value of these specimens comes at a cost (https://www.nytimes.com/2020/03/11/science/amber-myanmar-paleontologists.html). Where Burmese amber is mined in hazardous conditions, smuggled out of the country, and sold as gemstones, the most disheartening issue is that the recent surge of exciting scientific discoveries, particularly involving vertebrate fossils, has in part fueled the commercial trading of amber. -
Flood Pulse and Aquatic Habitat Dynamics of the Sentarum Floodplain Lakes Area
Flood Pulse and Aquatic Habitat Dynamics of The Sentarum Floodplain Lakes Area H. Hidayat a,*, Siti Aisyah a, Riky Kurniawan a, Iwan Ridwansyah a, Octavianto Samir a, a Gadis Sri Haryani a Research Center for Limnology-LIPI; Kompleks LIPI Cibinong, Jalan Raya Bogor, Km. 46, Cibinong 16911; *[email protected] Received 29 November 2020 Accepted 13 December 2020 Published 17 December 2020 Abstract The Lake Sentarum is a complex of floodplain lakes in the middle part of the Kapuas River system in West Kalimantan, Indonesia. The area has a great ecological and economic importance, however, the Sentarum lakes complex and its catchment area are generally threatened by deforestation, fire, monoculture agroindustry, and pollution.The objective of this research is to establish the hydrological characteristics of the Sentarum lakes area and to reveal the dynamics of aquatic habitat resulted from changing water levels. Data were collected during our field campaigns of 2013-2017 representing the seasons. The water level was measured using a pressure sensor placed at the Lake Sentarum National Park resort, while rainfall data were obtained from the data portal of the Tropical Rainfall Measuring Mission. Inundation monitoring was carried out using a time-lapse camera. A hydrological model is used to simulate water levels beyond measurement period. Water quality and fish sampling were carried out at the lake area. Vegetation observation was carried out at the selected riparian zone of the lake area using the line transect method. Water level records show that the Sentarum floodplain lakes have two peaks of inundation period following the bimodal pattern of rainfall in the equatorial Kapuas catchment. -
Quantum Machine Learning and Quantum Biomimetics: a Perspective
Quantum machine learning and quantum biomimetics: A perspective Lucas Lamata Departamento de F´ısicaAt´omica, Molecular y Nuclear, Universidad de Sevilla, 41080 Sevilla, Spain April 2020 Abstract. Quantum machine learning has emerged as an exciting and promising paradigm inside quantum technologies. It may permit, on the one hand, to carry out more efficient machine learning calculations by means of quantum devices, while, on the other hand, to employ machine learning techniques to better control quantum systems. Inside quantum machine learning, quantum reinforcement learning aims at developing \intelligent" quantum agents that may interact with the outer world and adapt to it, with the strategy of achieving some final goal. Another paradigm inside quantum machine learning is that of quantum autoencoders, which may allow one for employing fewer resources in a quantum device via a training process. Moreover, the field of quantum biomimetics aims at establishing analogies between biological and quantum systems, to look for previously inadvertent connections that may enable useful applications. Two recent examples are the concepts of quantum artificial life, as well as of quantum memristors. In this Perspective, we give an overview of these topics, describing the related research carried out by the scientific community. Keywords: Quantum machine learning; quantum biomimetics; quantum artificial intelligence; quantum reinforcement learning; quantum autoencoders; quantum artificial life; quantum memristors arXiv:2004.12076v2 [quant-ph] 30 May 2020 1. Introduction The field of quantum technologies has experienced a significant boost in the past five years. The interest of multinational companies such as Google, IBM, Microsoft, Intel, and Alibaba in this area has increased the worldwide competition and available funding not only from these firms, but also from national and supranational governments, such as the European Union [1, 2]. -

Stroboscopic High-Order Nonlinearity for Quantum Optomechanics ✉ Andrey A
www.nature.com/npjqi ARTICLE OPEN Stroboscopic high-order nonlinearity for quantum optomechanics ✉ Andrey A. Rakhubovsky 1 and Radim Filip 1 High-order quantum nonlinearity is an important prerequisite for the advanced quantum technology leading to universal quantum processing with large information capacity of continuous variables. Levitated optomechanics, a field where motion of dielectric particles is driven by precisely controlled tweezer beams, is capable of attaining the required nonlinearity via engineered potential landscapes of mechanical motion. Importantly, to achieve nonlinear quantum effects, the evolution caused by the free motion of mechanics and thermal decoherence have to be suppressed. For this purpose, we devise a method of stroboscopic application of a highly nonlinear potential to a mechanical oscillator that leads to the motional quantum non-Gaussian states exhibiting nonclassical negative Wigner function and squeezing of a nonlinear combination of mechanical quadratures. We test the method numerically by analyzing highly instable cubic potential with relevant experimental parameters of the levitated optomechanics, prove its feasibility within reach, and propose an experimental test. The method paves a road for experiments instantaneously transforming a ground state of mechanical oscillators to applicable nonclassical states by nonlinear optical force. npj Quantum Information (2021) 7:120 ; https://doi.org/10.1038/s41534-021-00453-8 1234567890():,; INTRODUCTION Moreover, the trapping potentials can be made time-dependent Quantum physics and technology with continuous variables (CVs)1 and manipulated at rates exceeding the rate of mechanical has achieved noticeable progress recently.

Electric Field Spectroscopy of Material Defects in Transmon Qubits
www.nature.com/npjqi ARTICLE OPEN Electric field spectroscopy of material defects in transmon qubits Jürgen Lisenfeld 1*, Alexander Bilmes1, Anthony Megrant2, Rami Barends2, Julian Kelly2, Paul Klimov2, Georg Weiss1, John M. Martinis2 and Alexey V. Ustinov1,3 Superconducting integrated circuits have demonstrated a tremendous potential to realize integrated quantum computing processors. However, the downside of the solid-state approach is that superconducting qubits suffer strongly from energy dissipation and environmental fluctuations caused by atomic-scale defects in device materials. Further progress towards upscaled quantum processors will require improvements in device fabrication techniques, which need to be guided by novel analysis methods to understand and prevent mechanisms of defect formation. Here, we present a technique to analyse individual defects in superconducting qubits by tuning them with applied electric fields. This provides a spectroscopy method to extract the defects’ energy distribution, electric dipole moments, and coherence times. Moreover, it enables one to distinguish defects residing in Josephson junction tunnel barriers from those at circuit interfaces. We find that defects at circuit interfaces are responsible for about 60% of the dielectric loss in the investigated transmon qubit sample. About 40% of all detected defects are contained in the tunnel barriers of the large-area parasitic Josephson junctions that occur collaterally in shadow evaporation, and only 3% are identified as strongly coupled defects, which -
