Constrained variational quantum eigensolver: Quantum computer search engine in the Fock space.

J Chem Theory Comput 2018 Dec 4. Epub 2018 Dec 4.

Variational quantum eigensolver (VQE) is an efficient computational method promising chemical accuracy in electronic structure calculations on a universal-gate quantum computer. However, such a simple task as computing the electronic energy of a hydrogen molecular cation, H+2 , is not possible for a general VQE protocol because the calculation will invariably collapse to a lower energy of the corresponding neutral form, H2. The origin of the problem is that VQE effectively performs an unconstrained energy optimization in the Fock space of the original electronic problem. Read More

Comparative Analysis of the Adhesive Proteins of the Adult Stalked Goose Barnacle Pollicipes pollicipes (Cirripedia: Pedunculata).

Mar Biotechnol (NY) 2018 Nov 10. Epub 2018 Nov 10.

CIIMAR/CIMAR - Interdisciplinary Centre of Marine and Environmental Research, University of Porto, Terminal de Cruzeiros do Porto de Leixões, Av. General Norton de Matos, s/n, 4450-208, Matosinhos, Portugal.

Adhesion in barnacles is still poorly understood. The cement gland secretes an insoluble multi-protein complex, which adheres very strongly to a variety of substrates in the presence of water. This adhesion mechanism is bioinspiring for the engineering of new adhesive materials, but to replicate this adhesive system, the genes coding for the cement constitutive proteins must be identified and elucidated, and their products characterised.

I-SceI Meganuclease-mediated transgenesis in the acorn worm, Saccoglossus kowalevskii.

Dev Biol 2019 Jan 6;445(1):8-15. Epub 2018 Nov 6.

Hopkins Marine Station, Department of Biology, Stanford University, 120 Oceanview Blvd., Pacific Grove, CA 93950, United States. Electronic address:

Hemichordates are a phylum of marine invertebrate deuterostomes that are closely related to chordates, and represent one of the most promising models to provide insights into early deuterostome evolution. The genome of the hemichordate, Saccoglossus kowalevskii, reveals an extensive set of non-coding elements conserved across all three deuterostome phyla. Functional characterization and cross-phyla comparisons of these putative regulatory elements will enable a better understanding of enhancer evolution, and subsequently how changes in gene regulation give rise to morphological innovation.

Pollen limitation as a main driver of fruiting dynamics in oak populations.

Ecol Lett 2018 Oct 15. Epub 2018 Oct 15.

Université de Lyon, Université Lyon 1, CNRS, Laboratoire de Biométrie et Biologie Evolutive, UMR 5558, F-69622, Villeurbanne, France.

In many perennial wind-pollinated plants, the dynamics of seed production is commonly known to be highly fluctuating from year to year and synchronised among individuals within populations. The proximate causes of such seeding dynamics, called masting, are still poorly understood in oak species that are widespread in the northern hemisphere, and whose fruiting dynamics dramatically impacts forest regeneration and biodiversity. Combining long-term surveys of oak airborne pollen amount and acorn production over large-scale field networks in temperate areas, and a mechanistic modelling approach, we found that the pollen dynamics is the key driver of oak masting.

Rapid aggregative and reproductive responses of weevils to masting of North American oaks counteract predator satiation.

Ecology 2018 Nov 28;99(11):2575-2582. Epub 2018 Sep 28.

Department of Biology, Wilkes University, Wilkes-Barre, Pennsylvania, 18766, USA.

The predator satiation hypothesis posits that masting helps plants escape seed predation through starvation of predators in lean years, followed by satiation of predators in mast years. Importantly, successful satiation requires sufficiently delayed bottom-up effects of seed availability on seed consumers. However, some seed consumers may be capable of quick aggregative and reproductive responses to masting, which may jeopardize positive density dependence of seed survival. Read More

Decadal post-fire succession of soil invertebrate communities is dependent on the soil surface properties in a northern temperate forest.

Sci Total Environ 2019 Jan 7;647:1058-1068. Epub 2018 Aug 7.

University of Michigan, Department of Ecology and Evolutionary Biology, Ann Arbor, MI, USA.

Although fires are common disturbances in North American forests, the extent to which soil invertebrate assemblages recover from burning remains unclear. Here, we examine long-term (14- to 101-yr) recoveries of soil invertebrate communities from common cut and burn treatments conducted at 6 to 26-yr intervals since 1911 in a deciduous forest in the upper Great Lakes region (USA). We characterize soil surface macro-invertebrate communities during both fall and spring across a long-term, experimental fire chronosequence to characterize invertebrate community recovery at decadal time-scales and community changes between seasons.

Dilemmas in the treatment of early-onset first-episode psychosis.

Ther Adv Psychopharmacol 2018 Aug 26;8(8):231-239. Epub 2018 Mar 26.

National and Specialist Acorn Lodge Inpatient Children's Unit, South London and the Maudsley NHS Foundation Trust, London, UK.

Early-onset first-episode psychosis (EOP) is a severe mental disorder that can pose a number of challenges to clinicians, young people and their families. Its assessment and differentiation from other neurodevelopmental and mental health conditions may at times be difficult, its treatment may not always lead to optimal outcomes and can be associated with significant side effects, and its long-term course and prognosis seem to be less favourable compared with the adult-onset disorder. In this paper, we discuss some dilemmas associated with the evaluation and management of EOP and propose approaches that can be used in the clinical decision-making process. Read More

Department of Biology, Case Western Reserve University, Cleveland, OH 44106, USA

The question of parallel evolution-what causes it, and how common it is-has long captured the interest of evolutionary biologists. Widespread urban development over the last century has driven rapid evolutionary responses on contemporary time scales, presenting a unique opportunity to test the predictability and parallelism of evolutionary change. Here we examine urban evolution in an acorn-dwelling ant species, focusing on the urban heat island signal and the ant's tolerance of these altered urban temperature regimes. Read More

Department of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853, USA.

According to the social intelligence hypothesis, understanding the cognitive demands of the social environment is key to understanding the evolution of intelligence. Many important socio-cognitive abilities, however, have primarily been studied in a narrow subset of the social environment-within-group social interactions-despite the fact that between-group social interactions often have a substantial effect on fitness. In particular, triadic awareness (knowledge about the relationships and associations between others) is critical for navigating many types of complex social interactions, yet no existing study has investigated whether wild animals can track associations between members of other social groups.

Marine Biological Laboratory, Graduate School of Science, Hiroshima University, Onomichi, Hiroshima, Japan.

Hemichordates are marine invertebrates that are closely related to chordates, but while their body plans are comparable to those of chordates, they possess a remarkable capacity for regeneration, even as adults. A small fragment is sufficient to form a complete individual. Unlike echinoderms, their larvae transform directly into adults; therefore, hemichordate systems offer clear morphological and molecular parallels between regeneration and development. Read More

Evolution of plasticity in the city: urban acorn ants can better tolerate more rapid increases in environmental temperature.

Conserv Physiol 2018 14;6(1):coy030. Epub 2018 Jun 14.

Hathaway Brown School, 19600 North Park Boulevard, Shaker Heights, OH, USA.

Because cities contain high levels of impervious surfaces and diminished buffering effects of vegetation cover, urbanized environments can warm faster over the day and exhibit more rapid warming over space due to greater thermal heterogeneity in these environments. Whether organismal physiologies can adapt to these more rapid spatio-temporal changes in temperature rise within cities is unknown, and exploring these responses can inform not only how plastic and evolutionary mechanisms shape organismal physiologies, but also the potential for organisms to cope with urban development. Here, we examined how plasticity in thermal tolerance under faster and slower rates of temperature change might evolve in response to the more rapid spatio-temporal temperature rise in cities.

Cornell Lab of Ornithology, Ithaca, NY 14850, USA.

Mistletoes are a widespread group of plants often considered to be hemiparasitic, having detrimental effects on growth and survival of their hosts. We studied the effects of the Pacific mistletoe, , a member of a largely autotrophic genus, on three species of deciduous California oaks. We found no effects of mistletoe presence on radial growth or survivorship and detected a significant positive relationship between mistletoe and acorn production. Read More

Treatment of acute kidney injury secondary to oak intoxication with hemodialysis in a miniature zebu.

J Vet Emerg Crit Care (San Antonio) 2018 Jul 13;28(4):361-365. Epub 2018 Jun 13.

Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Florida, Gainesville, FL, 32608.

Objective: To describe the successful management of acute kidney injury (AKI) secondary to oak intoxication using hemodialysis in a miniature zebu.

Case Summary: A 1-year-old male intact miniature zebu was presented for evaluation of a 2-day history of lethargy, anorexia, decreased urine production, and dry, firm stool. Initial diagnostics revealed severe azotemia and the bull was presumptively diagnosed with AKI secondary to oak intoxication due to free access to oak trees in the pasture. Read More

A comparative analysis of the avian skull: Woodpeckers and chickens.

J Mech Behav Biomed Mater 2018 Aug 2;84:273-280. Epub 2018 May 2.

Materials Science and Engineering Program, University of California, San Diego, La Jolla, CA 92093, USA; Department of Mechanical and Aerospace Engineering, University of California, San Diego, La Jolla, CA 92093, USA. Electronic address:

Woodpeckers peck at trees without any reported brain injury despite undergoing high impact loads. Amongst the adaptations allowing this is a highly functionalized impact-absorption system consisting of the head, beak, tongue and hyoid bone. This study aims to examine the anatomical structure, composition, and mechanical properties of the skull to determine its potential role in energy absorption and dissipation. Read More

Selective predation on acorn weevils by seed-caching Siberian chipmunk Tamias sibiricus in a tripartite interaction.

Oecologia 2018 Sep 19;188(1):149-158. Epub 2018 May 19.

College of Agriculture, Henan University of Science and Technology, Luoyang, 471023, China.

Although food-hoarding animals benefit plant seeds by generating predation pressure on granivorous insects, we lack experimental evidence of whether the tripartite interactions maintain a mutualistic relationship between the third trophic level and primary producers. Relying on the behavior of shelling, Siberian chipmunks (Tamias sibiricus) selectively consumed weevil larvae infested in acorns of Mongolian oak (Quercus mongolica) but chose the non-infested acorns to scatter-hoard. Shelling not only reduced volatile emission from acorns but also decreased cache loss to pilferers, weevil larvae and fungi, allowing T. Read More

A systematic review of associations between functional MRI activity and polygenic risk for schizophrenia and bipolar disorder.

Brain Imaging Behav 2018 May 10. Epub 2018 May 10.

Department of Neuroimaging, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, UK.

Genetic factors account for up to 80% of the liability for schizophrenia (SCZ) and bipolar disorder (BD). Genome-wide association studies have successfully identified several genes associated with increased risk for both disorders. This has allowed researchers to model the aggregate effect of genes associated with disease status and create a polygenic risk score (PGRS) for each individual. Read More

Tick-borne disease risk in a forest food web.

Ecology 2018 Jul 11;99(7):1562-1573. Epub 2018 Jun 11.

Cary Institute of Ecosystem Studies, Millbrook, New York, 12545, USA.

Changes to the community ecology of hosts for zoonotic pathogens, particularly rodents, are likely to influence the emergence and prevalence of zoonotic diseases worldwide. However, the complex interactions between abiotic factors, pathogens, vectors, hosts, and both food resources and predators of hosts are difficult to disentangle. Here we (1) use 19 yr of data from six large field plots in southeastern New York to compare the effects of hypothesized drivers of interannual variation in Lyme disease risk, including the abundance of acorns, rodents, and deer, as well as a series of climate variables; and (2) employ landscape epidemiology to explore how variation in predator community structure and forest cover influences spatial variation in the infection prevalence of ticks for the Lyme disease bacterium, Borrelia burgdorferi, and two other important tick-borne pathogens, Anaplasma phagocytophilum and Babesia microti.
