Density, short-range order and the quark-gluon plasma

We study the thermal part of the energy density spatial correlator in the quark-gluon plasma. We describe its qualitative form at high temperatures. We then calculate it out to distances approx. 1.5/T in SU(3) gauge theory lattice simulations for the range of temperatures 0.9<= T/T_c<= 2.2. The vacuum-subtracted correlator exhibits non-monotonic behavior, and is almost conformal by 2T_c. Its broad maximum at r approx. 0.6/T suggests a dense medium with only weak short-range order, similar to a non-relativistic fluid near the liquid-gas phase transition, where eta/s is minimal.Comment: 4 pages, 4 figure

Large-scale genomic analysis reveals the genetic cost of chicken domestication

none43Background: Species domestication is generally characterized by the exploitation of high-impact mutations through processes that involve complex shifting demographics of domesticated species. These include not only inbreeding and artificial selection that may lead to the emergence of evolutionary bottlenecks, but also post-divergence gene flow and introgression. Although domestication potentially affects the occurrence of both desired and undesired mutations, the way wild relatives of domesticated species evolve and how expensive the genetic cost underlying domestication is remain poorly understood. Here, we investigated the demographic history and genetic load of chicken domestication. Results: We analyzed a dataset comprising over 800 whole genomes from both indigenous chickens and wild jungle fowls. We show that despite having a higher genetic diversity than their wild counterparts (average π, 0.00326 vs. 0.00316), the red jungle fowls, the present-day domestic chickens experienced a dramatic population size decline during their early domestication. Our analyses suggest that the concomitant bottleneck induced 2.95% more deleterious mutations across chicken genomes compared with red jungle fowls, supporting the “cost of domestication” hypothesis. Particularly, we find that 62.4% of deleterious SNPs in domestic chickens are maintained in heterozygous states and masked as recessive alleles, challenging the power of modern breeding programs to effectively eliminate these genetic loads. Finally, we suggest that positive selection decreases the incidence but increases the frequency of deleterious SNPs in domestic chicken genomes. Conclusion: This study reveals a new landscape of demographic history and genomic changes associated with chicken domestication and provides insight into the evolutionary genomic profiles of domesticated animals managed under modern human selection.openWang M.-S.; Zhang J.-J.; Guo X.; Li M.; Meyer R.; Ashari H.; Zheng Z.-Q.; Wang S.; Peng M.-S.; Jiang Y.; Thakur M.; Suwannapoom C.; Esmailizadeh A.; Hirimuthugoda N.Y.; Zein M.S.A.; Kusza S.; Kharrati-Koopaee H.; Zeng L.; Wang Y.-M.; Yin T.-T.; Yang M.-M.; Li M.-L.; Lu X.-M.; Lasagna E.; Ceccobelli S.; Gunwardana H.G.T.N.; Senasig T.M.; Feng S.-H.; Zhang H.; Bhuiyan A.K.F.H.; Khan M.S.; Silva G.L.L.P.; Thuy L.T.; Mwai O.A.; Ibrahim M.N.M.; Zhang G.; Qu K.-X.; Hanotte O.; Shapiro B.; Bosse M.; Wu D.-D.; Han J.-L.; Zhang Y.-P.Wang, M. -S.; Zhang, J. -J.; Guo, X.; Li, M.; Meyer, R.; Ashari, H.; Zheng, Z. -Q.; Wang, S.; Peng, M. -S.; Jiang, Y.; Thakur, M.; Suwannapoom, C.; Esmailizadeh, A.; Hirimuthugoda, N.

Vector screening masses in the quark-gluon plasma and their physical significance

Static and non-static thermal screening states that couple to the conserved vector current are investigated in the high-temperature phase of QCD. Their masses and couplings to the current are determined at weak coupling, as well as using two-flavor lattice QCD simulations. A consistent picture emerges from the comparison, providing evidence that non-static Matsubara modes can indeed be treated perturbatively. We elaborate on the physical significance of the screening masses.Comment: 4 pages, 3 figures. Submitted as a contribution to the proceedings of the Quark Matter 2014 conference (talk given by H. Meyer

A relation between screening masses and real-time rates

Thermal screening masses related to the conserved vector current are determined for the case that the current carries a non-zero Matsubara frequency, both in a weak-coupling approach and through lattice QCD. We point out that such screening masses are sensitive to the same infrared physics as light-cone real-time rates. In particular, on the perturbative side, the inhomogeneous Schrodinger equation determining screening correlators is shown to have the same general form as the equation implementing LPM resummation for the soft-dilepton and photon production rates from a hot QCD plasma. The static potential appearing in the equation is identical to that whose soft part has been determined up to NLO and on the lattice in the context of jet quenching. Numerical results based on this potential suggest that screening masses overshoot the free results (multiples of 2piT) more strongly than at zero Matsubara frequency. Four-dimensional lattice simulations in two-flavour QCD at temperatures of 250 and 340 MeV confirm the non-static screening masses at the 10% level. Overall our results lend support to studies of jet quenching based on the same potential at T > 250 MeV.Comment: 32 pages. v2: clarifications added, typos corrected; published versio

A.Ticks transmit more pathogens to humans and animals than any other arthropod. We describe the 2.1 Gbp nuclear genome of the tick, Ixodes scapularis (Say), which vectors pathogens that cause Lyme disease, human granulocytic anaplasmosis, babesiosis and other diseases. The large genome reflects accumulation of repetitive DNA, new lineages of retro-transposons, and gene architecture patterns resembling ancient metazoans rather than pancrustaceans. Annotation of scaffolds representing similar to 57% of the genome, reveals 20,486 protein-coding genes and expansions of gene families associated with tick-host interactions. We report insights from genome analyses into parasitic processes unique to ticks, including host 'questing', prolonged feeding, cuticle synthesis, blood meal concentration, novel methods of haemoglobin digestion, haem detoxification, vitellogenesis and prolonged off-host survival. We identify proteins associated with the agent of human granulocytic anaplasmosis, an emerging disease, and the encephalitis-causing Langat virus, and a population structure correlated to life-history traits and transmission of the Lyme disease agent

Protection gaps and restoration opportunities for primary forests in Europe

none31siAims: Primary forests are critical for forest biodiversity and provide key ecosystem services. In Europe, these forests are particularly scarce and it is unclear whether they are sufficiently protected. Here we aim to: (a) understand whether extant primary forests are representative of the range of naturally occurring forest types, (b) identify forest types which host enough primary forest under strict protection to meet conservation targets and (c) highlight areas where restoration is needed and feasible. Location: Europe. Methods: We combined a unique geodatabase of primary forests with maps of forest cover, potential natural vegetation, biogeographic regions and protected areas to quantify the proportion of extant primary forest across Europe's forest types and to identify gaps in protection. Using spatial predictions of primary forest locations to account for underreporting of primary forests, we then highlighted areas where restoration could complement protection. Results: We found a substantial bias in primary forest distribution across forest types. Of the 54 forest types we assessed, six had no primary forest at all, and in two-thirds of forest types, less than 1% of forest was primary. Even if generally protected, only ten forest types had more than half of their primary forests strictly protected. Protecting all documented primary forests requires expanding the protected area networks by 1,132&nbsp;km2 (19,194&nbsp;km2 when including also predicted primary forests). Encouragingly, large areas of non-primary forest existed inside protected areas for most types, thus presenting restoration opportunities. Main conclusion: Europe's primary forests are in a perilous state, as also acknowledged by EU's “Biodiversity Strategy for 2030.” Yet, there are considerable opportunities for ensuring better protection and restoring primary forest structure, composition and functioning, at least partially. We advocate integrated policy reforms that explicitly account for the irreplaceable nature of primary forests and ramp up protection and restoration efforts alike.openSabatini F.M.; Keeton W.S.; Lindner M.; Svoboda M.; Verkerk P.J.; Bauhus J.; Bruelheide H.; Burrascano S.; Debaive N.; Duarte I.; Garbarino M.; Grigoriadis N.; Lombardi F.; Mikolas M.; Meyer P.; Motta R.; Mozgeris G.; Nunes L.; Odor P.; Panayotov M.; Ruete A.; Simovski B.; Stillhard J.; Svensson J.; Szwagrzyk J.; Tikkanen O.-P.; Vandekerkhove K.; Volosyanchuk R.; Vrska T.; Zlatanov T.; Kuemmerle T.Sabatini F.M.; Keeton W.S.; Lindner M.; Svoboda M.; Verkerk P.J.; Bauhus J.; Bruelheide H.; Burrascano S.; Debaive N.; Duarte I.; Garbarino M.; Grigoriadis N.; Lombardi F.; Mikolas M.; Meyer P.; Motta R.; Mozgeris G.; Nunes L.; Odor P.; Panayotov M.; Ruete A.; Simovski B.; Stillhard J.; Svensson J.; Szwagrzyk J.; Tikkanen O.-P.; Vandekerkhove K.; Volosyanchuk R.; Vrska T.; Zlatanov T.; Kuemmerle T

Assessing the impact of COVID-19 on liver cancer management (CERO-19)

open85siBackground &amp; Aims: The coronavirus disease 2019 (COVID-19) pandemic has posed unprecedented challenges to healthcare systems and it may have heavily impacted patients with liver cancer (LC). Herein, we evaluated whether the schedule of LC screening or procedures has been interrupted or delayed because of the COVID-19 pandemic. Methods: An international survey evaluated the impact of the COVID-19 pandemic on clinical practice and clinical trials from March 2020 to June 2020, as the first phase of a multicentre, international, and observational project. The focus was on patients with hepatocellular carcinoma or intrahepatic cholangiocarcinoma, cared for around the world during the first COVID-19 pandemic wave. Results: Ninety-one centres expressed interest to participate and 76 were included in the analysis, from Europe, South America, North America, Asia, and Africa (73.7%, 17.1%, 5.3%, 2.6%, and 1.3% per continent, respectively). Eighty-seven percent of the centres modified their clinical practice: 40.8% the diagnostic procedures, 80.9% the screening programme, 50% cancelled curative and/or palliative treatments for LC, and 41.7% modified the liver transplantation programme. Forty-five out of 69 (65.2%) centres in which clinical trials were running modified their treatments in that setting, but 58.1% were able to recruit new patients. The phone call service was modified in 51.4% of centres which had this service before the COVID-19 pandemic (n = 19/37). Conclusions: The first wave of the COVID-19 pandemic had a tremendous impact on the routine care of patients with liver cancer. Modifications in screening, diagnostic, and treatment algorithms may have significantly impaired the outcome of patients. Ongoing data collection and future analyses will report the benefits and disadvantages of the strategies implemented, aiding future decision-making. Lay summary: The coronavirus disease 2019 (COVID-19) pandemic has posed unprecedented challenges to healthcare systems globally. Herein, we assessed the impact of the first wave pandemic on patients with liver cancer and found that routine care for these patients has been majorly disrupted, which could have a significant impact on outcomes.openMunoz-Martinez S.; Sapena V.; Forner A.; Nault J.-C.; Sapisochin G.; Rimassa L.; Sangro B.; Bruix J.; Sanduzzi-Zamparelli M.; Holowko W.; El Kassas M.; Mocan T.; Bouattour M.; Merle P.; Hoogwater F.J.H.; Alqahtani S.A.; Reeves H.L.; Pinato D.J.; Giorgakis E.; Meyer T.; Villadsen G.E.; Wege H.; Salati M.; Minguez B.; Di Costanzo G.G.; Roderburg C.; Tacke F.; Varela M.; Galle P.R.; Alvares-da-Silva M.R.; Trojan J.; Bridgewater J.; Cabibbo G.; Toso C.; Lachenmayer A.; Casadei-Gardini A.; Toyoda H.; Ludde T.; Villani R.; Matilla Pena A.M.; Guedes Leal C.R.; Ronzoni M.; Delgado M.; Perello C.; Pascual S.; Lledo J.L.; Argemi J.; Basu B.; da Fonseca L.; Acevedo J.; Siebenhuner A.R.; Braconi C.; Meyers B.M.; Granito A.; Sala M.; Rodriguez-Lope C.; Blaise L.; Romero-Gomez M.; Pinero F.; Gomez D.; Mello V.; Pinheiro Alves R.C.; Franca A.; Branco F.; Brandi G.; Pereira G.; Coll S.; Guarino M.; Benitez C.; Anders M.M.; Bandi J.C.; Vergara M.; Calvo M.; Peck-Radosavljevic M.; Garcia-Juarez I.; Cardinale V.; Lozano M.; Gambato M.; Okolicsanyi S.; Morales-Arraez D.; Elvevi A.; Munoz A.E.; Lue A.; Iavarone M.; Reig M.Munoz-Martinez S.; Sapena V.; Forner A.; Nault J.-C.; Sapisochin G.; Rimassa L.; Sangro B.; Bruix J.; Sanduzzi-Zamparelli M.; Holowko W.; El Kassas M.; Mocan T.; Bouattour M.; Merle P.; Hoogwater F.J.H.; Alqahtani S.A.; Reeves H.L.; Pinato D.J.; Giorgakis E.; Meyer T.; Villadsen G.E.; Wege H.; Salati M.; Minguez B.; Di Costanzo G.G.; Roderburg C.; Tacke F.; Varela M.; Galle P.R.; Alvares-da-Silva M.R.; Trojan J.; Bridgewater J.; Cabibbo G.; Toso C.; Lachenmayer A.; Casadei-Gardini A.; Toyoda H.; Ludde T.; Villani R.; Matilla Pena A.M.; Guedes Leal C.R.; Ronzoni M.; Delgado M.; Perello C.; Pascual S.; Lledo J.L.; Argemi J.; Basu B.; da Fonseca L.; Acevedo J.; Siebenhuner A.R.; Braconi C.; Meyers B.M.; Granito A.; Sala M.; Rodriguez-Lope C.; Blaise L.; Romero-Gomez M.; Pinero F.; Gomez D.; Mello V.; Pinheiro Alves R.C.; Franca A.; Branco F.; Brandi G.; Pereira G.; Coll S.; Guarino M.; Benitez C.; Anders M.M.; Bandi J.C.; Vergara M.; Calvo M.; Peck-Radosavljevic M.; Garcia-Juarez I.; Cardinale V.; Lozano M.; Gambato M.; Okolicsanyi S.; Morales-Arraez D.; Elvevi A.; Munoz A.E.; Lue A.; Iavarone M.; Reig M

25 years of joint Yedoma Ice Complex studies in Arctic Russia, especially in Sakha/Yakutia

Since 1994, permafrost deposits of the Siberian Yedoma region have been in the focus of the joint Russian-German scientific cooperation in terrestrial Polar research (Figure 1). These studies focused on cryostratigraphic, geochemical, geochronological, and paleontological characteristics at more than 25 individual study sites of the late Pleistocene Yedoma Ice Complex in Siberia and provided a detailed insight into the paleoenvironments and paleoclimate for the westernmost part of Beringia. The multidisciplinary investigations resulted in new ideas and discussions in the ongoing scientific debate on the origin of Yedoma Ice Complex and the main periglacial processes involved in its formation (1,2,3). The Yedoma Ice Complex is an ice-rich type of permafrost deposit widely distributed across Beringia. The Ice Complex aggradation is mainly controlled by the growth of syngenetic ice wedge polygons contributing up to 60 vol% of the entire formation. The clastic sedimentation of ice-oversaturated Yedoma deposits with considerable organic matter content is further controlled by local conditions such as source rocks and periglacial weathering processes, paleotopography, and temporary surface stabilization with autochthonous peat growth and soil formation. Key processes include alluvial, fluvial, and niveo-aeolian transport (4) as well as accumulation in ponding waters and continued in-situ frost weathering over millennial time-scales. Important post-depositional processes affecting Yedoma deposits are solifluction, cryoturbation, and pedogenesis. Major joint Russian-German field studies were conducted on Taymyr Peninsula (5,6,7,8,9,10,11), along the western and central Laptev Sea coasts (12,13,14,15,16,17,18), in the Lena Delta (19,20,21,22), on islands of the New Siberian Archipelago (23,24,25,26,27,28), and the adjacent mainland (29). Further study sites were conducted in the Kolyma Lowland (30), the Yana Highlands (31,32), in the foothills of the Verkhoyan Mountains (33,34,35,36), and in Central Yakutia (37). Comprehensive sampling and further analytical work included not only the Yedoma Ice Complex itself but also included its stratigraphic context of older underlying sequences and younger overlying deposits. The latter often are subaerial or subaquatic deposits associated with late-Glacial to Holocene thermokarst dynamics that led to Yedoma degradation during the deglacial and Holocene warming of these regions (38,39,40). Figure 1: Joint Russian-German fieldwork sites in NE Siberia labeled with the year of expedition. Besides geomorphological and cryolithological studies, extensive paleo-ecological investigations were carried out on zoological (41,42,43,44,45) and botanic fossils (46,47,48,49,50,51) to derive quantitative and qualitative reconstructions late Pleistocene Beringian environments and climate conditions. New methods in geochronology were also tested (52,53,54,55). In addition to the sedimentary components of the frozen deposits, segregated ground ice and in particular the large syngenetic ice wedges of Yedoma Ice Complex were also studied as geochemical and stable isotope archives of paleoclimate (56,57,58, 59,60,61,62). In addition, a range of remote sensing methods in combination with GIS analyses (63,64,65) and geophysical surveys (66) were used for large-scale analyses of landscape changes associated with Yedoma Ice Complex degradation (67,68,69). In the last few years, an additional important focus has been on using modern biogeochemical methods of organic matter analysis to characterize the frozen organic matter in Yedoma Ice Complex deposits and for permafrost carbon pool calculations (70, 71,72,73,74,75,76,77) as well as microbiological studies (78) and genetic studies on fossil DNA (79,80). The rich body of scientific data and literature produced in Russian-German co-authorship within the more than 25 years of joint research on Yedoma Ice Complex represents an important cornerstone for understanding the Late Quaternary evolution of Siberian Yedoma regions, its role in the Earth System, and its feedbacks with climate and ecosystems.
