    GWAS of blood cell traits identifies novel associated loci and epistatic interactions in Caucasian and African-American children (2013)
    Oxford University Press
    Details
    Publication Date: 2013-03-15
    Description: Hematological traits are important clinical indicators, the genetic determinants of which have not been fully investigated. Common measures of hematological traits include red blood cell (RBC) count, hemoglobin concentration (HGB), hematocrit (HCT), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC), mean corpuscular volume (MCV), platelet count (PLT) and white blood cell (WBC) count. We carried out a genome-wide association study of the eight common hematological traits among 7943 African-American children and 6234 Caucasian children. In African Americans, we report five novel associations of HBE1 variants with HCT and MCHC, the alpha-globin gene cluster variants with RBC and MCHC, and a variant at the ARHGEF3 locus with PLT, as well as replication of four previously reported loci at genome-wide significance. In Caucasians, we report a novel association of variants at the COPZ1 locus with PLT as well as replication of four previously reported loci at genome-wide significance. Extended analysis of an association observed between MCH and the alpha-globin gene cluster variants demonstrated independent effects and epistatic interaction at the locus, impacting the risk of iron deficiency anemia in African Americans with specific genotype states. In summary, we extend the understanding of genetic variants underlying hematological traits based on analyses in African-American children.

    Isotope fractionation in silicate melts by thermal diffusion (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-03-20
    Description: The phenomenon of thermal diffusion (mass diffusion driven by a temperature gradient, known as the Ludwig-Soret effect) has been investigated for over 150 years, but an understanding of its underlying physical basis remains elusive. A significant hurdle in studying thermal diffusion has been the difficulty of characterizing it. Extensive experiments over the past century have established that the Soret coefficient, S(T) (a single parameter that describes the steady-state result of thermal diffusion), is highly sensitive to many factors. This sensitivity makes it very difficult to obtain a robust characterization of thermal diffusion, even for a single material. Here we show that for thermal diffusion experiments that span a wide range in composition and temperature, the difference in S(T) between isotopes of diffusing elements that are network modifiers (iron, calcium and magnesium) is independent of the composition and temperature. On the basis of this finding, we propose an additive decomposition for the functional form of S(T) and argue that a theoretical approach based on local thermodynamic equilibrium holds promise for describing thermal diffusion in silicate melts and other complex solutions. Our results lead to a simple and robust framework for characterizing isotope fractionation by thermal diffusion in natural and synthetic systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, F -- Chakraborty, P -- Lundstrom, C C -- Holmden, C -- Glessner, J J G -- Kieffer, S W -- Lesher, C E -- England -- Nature. 2010 Mar 18;464(7287):396-400. doi: 10.1038/nature08840.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, University of Illinois, Urbana, Illinois 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20237567" target="_blank"〉PubMed〈/a〉

    De novo mutations in histone-modifying genes in congenital heart disease (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-05-15
    Description: Congenital heart disease (CHD) is the most frequent birth defect, affecting 0.8% of live births. Many cases occur sporadically and impair reproductive fitness, suggesting a role for de novo mutations. Here we compare the incidence of de novo mutations in 362 severe CHD cases and 264 controls by analysing exome sequencing of parent-offspring trios. CHD cases show a significant excess of protein-altering de novo mutations in genes expressed in the developing heart, with an odds ratio of 7.5 for damaging (premature termination, frameshift, splice site) mutations. Similar odds ratios are seen across the main classes of severe CHD. We find a marked excess of de novo mutations in genes involved in the production, removal or reading of histone 3 lysine 4 (H3K4) methylation, or ubiquitination of H2BK120, which is required for H3K4 methylation. There are also two de novo mutations in SMAD2, which regulates H3K27 methylation in the embryonic left-right organizer. The combination of both activating (H3K4 methylation) and inactivating (H3K27 methylation) chromatin marks characterizes 'poised' promoters and enhancers, which regulate expression of key developmental genes. These findings implicate de novo point mutations in several hundreds of genes that collectively contribute to approximately 10% of severe CHD.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3706629/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3706629/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaidi, Samir -- Choi, Murim -- Wakimoto, Hiroko -- Ma, Lijiang -- Jiang, Jianming -- Overton, John D -- Romano-Adesman, Angela -- Bjornson, Robert D -- Breitbart, Roger E -- Brown, Kerry K -- Carriero, Nicholas J -- Cheung, Yee Him -- Deanfield, John -- DePalma, Steve -- Fakhro, Khalid A -- Glessner, Joseph -- Hakonarson, Hakon -- Italia, Michael J -- Kaltman, Jonathan R -- Kaski, Juan -- Kim, Richard -- Kline, Jennie K -- Lee, Teresa -- Leipzig, Jeremy -- Lopez, Alexander -- Mane, Shrikant M -- Mitchell, Laura E -- Newburger, Jane W -- Parfenov, Michael -- Pe'er, Itsik -- Porter, George -- Roberts, Amy E -- Sachidanandam, Ravi -- Sanders, Stephan J -- Seiden, Howard S -- State, Mathew W -- Subramanian, Sailakshmi -- Tikhonova, Irina R -- Wang, Wei -- Warburton, Dorothy -- White, Peter S -- Williams, Ismee A -- Zhao, Hongyu -- Seidman, Jonathan G -- Brueckner, Martina -- Chung, Wendy K -- Gelb, Bruce D -- Goldmuntz, Elizabeth -- Seidman, Christine E -- Lifton, Richard P -- 5U54HG006504/HG/NHGRI NIH HHS/ -- F30 HL123238/HL/NHLBI NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- U01 HG006546/HG/NHGRI NIH HHS/ -- U01 HL098123/HL/NHLBI NIH HHS/ -- U01 HL098147/HL/NHLBI NIH HHS/ -- U01 HL098153/HL/NHLBI NIH HHS/ -- U01 HL098162/HL/NHLBI NIH HHS/ -- U01 HL098163/HL/NHLBI NIH HHS/ -- U01-HL098123/HL/NHLBI NIH HHS/ -- U01-HL098147/HL/NHLBI NIH HHS/ -- U01-HL098153/HL/NHLBI NIH HHS/ -- U01-HL098162/HL/NHLBI NIH HHS/ -- U01-HL098163/HL/NHLBI NIH HHS/ -- U01-HL098188/HL/NHLBI NIH HHS/ -- U54 HG006504/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jun 13;498(7453):220-3. doi: 10.1038/nature12141.

    Cntnap4 differentially contributes to GABAergic and dopaminergic synaptic transmission (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-05-30
    Description: Although considerable evidence suggests that the chemical synapse is a lynchpin underlying affective disorders, how molecular insults differentially affect specific synaptic connections remains poorly understood. For instance, Neurexin 1a and 2 (NRXN1 and NRXN2) and CNTNAP2 (also known as CASPR2), all members of the neurexin superfamily of transmembrane molecules, have been implicated in neuropsychiatric disorders. However, their loss leads to deficits that have been best characterized with regard to their effect on excitatory cells. Notably, other disease-associated genes such as BDNF and ERBB4 implicate specific interneuron synapses in psychiatric disorders. Consistent with this, cortical interneuron dysfunction has been linked to epilepsy, schizophrenia and autism. Using a microarray screen that focused upon synapse-associated molecules, we identified Cntnap4 (contactin associated protein-like 4, also known as Caspr4) as highly enriched in developing murine interneurons. In this study we show that Cntnap4 is localized presynaptically and its loss leads to a reduction in the output of cortical parvalbumin (PV)-positive GABAergic (gamma-aminobutyric acid producing) basket cells. Paradoxically, the loss of Cntnap4 augments midbrain dopaminergic release in the nucleus accumbens. In Cntnap4 mutant mice, synaptic defects in these disease-relevant neuronal populations are mirrored by sensory-motor gating and grooming endophenotypes; these symptoms could be pharmacologically reversed, providing promise for therapeutic intervention in psychiatric disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4281262/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4281262/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karayannis, T -- Au, E -- Patel, J C -- Kruglikov, I -- Markx, S -- Delorme, R -- Heron, D -- Salomon, D -- Glessner, J -- Restituito, S -- Gordon, A -- Rodriguez-Murillo, L -- Roy, N C -- Gogos, J A -- Rudy, B -- Rice, M E -- Karayiorgou, M -- Hakonarson, H -- Keren, B -- Huguet, G -- Bourgeron, T -- Hoeffer, C -- Tsien, R W -- Peles, E -- Fishell, G -- NS30989/NS/NINDS NIH HHS/ -- NS50220/NS/NINDS NIH HHS/ -- P01 NS074972/NS/NINDS NIH HHS/ -- R01 DA033811/DA/NIDA NIH HHS/ -- R01 MH071679/MH/NIMH NIH HHS/ -- R01 NS030989/NS/NINDS NIH HHS/ -- R01 NS036362/NS/NINDS NIH HHS/ -- R01 NS050220/NS/NINDS NIH HHS/ -- R01 NS074972/NS/NINDS NIH HHS/ -- R01 NS081297/NS/NINDS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2014 Jul 10;511(7508):236-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24870235" target="_blank"〉PubMed〈/a〉

    The landscape of recombination in African Americans (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-07-22
    Description: Recombination, together with mutation, gives rise to genetic variation in populations. Here we leverage the recent mixture of people of African and European ancestry in the Americas to build a genetic map measuring the probability of crossing over at each position in the genome, based on about 2.1 million crossovers in 30,000 unrelated African Americans. At intervals of more than three megabases it is nearly identical to a map built in Europeans. At finer scales it differs significantly, and we identify about 2,500 recombination hotspots that are active in people of West African ancestry but nearly inactive in Europeans. The probability of a crossover at these hotspots is almost fully controlled by the alleles an individual carries at PRDM9 (P value 〈 10(-245)). We identify a 17-base-pair DNA sequence motif that is enriched in these hotspots, and is an excellent match to the predicted binding target of PRDM9 alleles common in West Africans and rare in Europeans. Sites of this motif are predicted to be risk loci for disease-causing genomic rearrangements in individuals carrying these alleles. More generally, this map provides a resource for research in human genetic variation and evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154982/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinch, Anjali G -- Tandon, Arti -- Patterson, Nick -- Song, Yunli -- Rohland, Nadin -- Palmer, Cameron D -- Chen, Gary K -- Wang, Kai -- Buxbaum, Sarah G -- Akylbekova, Ermeg L -- Aldrich, Melinda C -- Ambrosone, Christine B -- Amos, Christopher -- Bandera, Elisa V -- Berndt, Sonja I -- Bernstein, Leslie -- Blot, William J -- Bock, Cathryn H -- Boerwinkle, Eric -- Cai, Qiuyin -- Caporaso, Neil -- Casey, Graham -- Cupples, L Adrienne -- Deming, Sandra L -- Diver, W Ryan -- Divers, Jasmin -- Fornage, Myriam -- Gillanders, Elizabeth M -- Glessner, Joseph -- Harris, Curtis C -- Hu, Jennifer J -- Ingles, Sue A -- Isaacs, William -- John, Esther M -- Kao, W H Linda -- Keating, Brendan -- Kittles, Rick A -- Kolonel, Laurence N -- Larkin, Emma -- Le Marchand, Loic -- McNeill, Lorna H -- Millikan, Robert C -- Murphy, Adam -- Musani, Solomon -- Neslund-Dudas, Christine -- Nyante, Sarah -- Papanicolaou, George J -- Press, Michael F -- Psaty, Bruce M -- Reiner, Alex P -- Rich, Stephen S -- Rodriguez-Gil, Jorge L -- Rotter, Jerome I -- Rybicki, Benjamin A -- Schwartz, Ann G -- Signorello, Lisa B -- Spitz, Margaret -- Strom, Sara S -- Thun, Michael J -- Tucker, Margaret A -- Wang, Zhaoming -- Wiencke, John K -- Witte, John S -- Wrensch, Margaret -- Wu, Xifeng -- Yamamura, Yuko -- Zanetti, Krista A -- Zheng, Wei -- Ziegler, Regina G -- Zhu, Xiaofeng -- Redline, Susan -- Hirschhorn, Joel N -- Henderson, Brian E -- Taylor, Herman A Jr -- Price, Alkes L -- Hakonarson, Hakon -- Chanock, Stephen J -- Haiman, Christopher A -- Wilson, James G -- Reich, David -- Myers, Simon R -- 090532/Wellcome Trust/United Kingdom -- CA060691/CA/NCI NIH HHS/ -- CA092447/CA/NCI NIH HHS/ -- CA100374/CA/NCI NIH HHS/ -- CA100598/CA/NCI NIH HHS/ -- CA1116460/CA/NCI NIH HHS/ -- CA1116460S1/CA/NCI NIH HHS/ -- CA121197/CA/NCI NIH HHS/ -- CA121197S2/CA/NCI NIH HHS/ -- CA127219/CA/NCI NIH HHS/ -- CA1326792/CA/NCI NIH HHS/ -- CA140388/CA/NCI NIH HHS/ -- CA141716/CA/NCI NIH HHS/ -- CA148085/CA/NCI NIH HHS/ -- CA148127/CA/NCI NIH HHS/ -- CA22453/CA/NCI NIH HHS/ -- CA54281/CA/NCI NIH HHS/ -- CA55769/CA/NCI NIH HHS/ -- CA58223/CA/NCI NIH HHS/ -- CA63464/CA/NCI NIH HHS/ -- CA68485/CA/NCI NIH HHS/ -- CA68578/CA/NCI NIH HHS/ -- CA77305/CA/NCI NIH HHS/ -- CA87895/CA/NCI NIH HHS/ -- CA88164/CA/NCI NIH HHS/ -- ES007784/ES/NIEHS NIH HHS/ -- ES011126/ES/NIEHS NIH HHS/ -- ES06717/ES/NIEHS NIH HHS/ -- ES10126/ES/NIEHS NIH HHS/ -- GM08016/GM/NIGMS NIH HHS/ -- GM091332/GM/NIGMS NIH HHS/ -- HD33175/HD/NICHD NIH HHS/ -- HG004726/HG/NHGRI NIH HHS/ -- HHSN268200960009C/PHS HHS/ -- HL084107/HL/NHLBI NIH HHS/ -- N01-HC-65226/HC/NHLBI NIH HHS/ -- P30 ES010126/ES/NIEHS NIH HHS/ -- R01 CA052689/CA/NCI NIH HHS/ -- R01 CA092447/CA/NCI NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- R01 HL084107-04/HL/NHLBI NIH HHS/ -- R01-CA73629/CA/NCI NIH HHS/ -- U01 HG004168/HG/NHGRI NIH HHS/ -- U01 HG004168-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jul 20;476(7359):170-5. doi: 10.1038/nature10336.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Human Genetics, Oxford University, Roosevelt Drive, Oxford OX3 7BN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21775986" target="_blank"〉PubMed〈/a〉

    Genetic risk and a primary role for cell-mediated immune mechanisms in multiple sclerosis (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-08-13
    Description: Multiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk. Modestly powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3182531/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009"

    Integrative genomics identifies LMO1 as a neuroblastoma oncogene (2010)

    Description: Neuroblastoma is a childhood cancer of the sympathetic nervous system that accounts for approximately 10% of all paediatric oncology deaths. To identify genetic risk factors for neuroblastoma, we performed a genome-wide association study (GWAS) on 2,251 patients and 6,097 control subjects of European ancestry from four case series. Here we report a significant association within LIM domain only 1 (LMO1) at 11p15.4 (rs110419, combined P = 5.2 x 10(-16), odds ratio of risk allele = 1.34 (95% confidence interval 1.25-1.44)). The signal was enriched in the subset of patients with the most aggressive form of the disease. LMO1 encodes a cysteine-rich transcriptional regulator, and its paralogues (LMO2, LMO3 and LMO4) have each been previously implicated in cancer. In parallel, we analysed genome-wide DNA copy number alterations in 701 primary tumours. We found that the LMO1 locus was aberrant in 12.4% through a duplication event, and that this event was associated with more advanced disease (P 〈 0.0001) and survival (P = 0.041). The germline single nucleotide polymorphism (SNP) risk alleles and somatic copy number gains were associated with increased LMO1 expression in neuroblastoma cell lines and primary tumours, consistent with a gain-of-function role in tumorigenesis. Short hairpin RNA (shRNA)-mediated depletion of LMO1 inhibited growth of neuroblastoma cells with high LMO1 expression, whereas forced expression of LMO1 in neuroblastoma cells with low LMO1 expression enhanced proliferation. These data show that common polymorphisms at the LMO1 locus are strongly associated with susceptibility to developing neuroblastoma, but also may influence the likelihood of further somatic alterations at this locus, leading to malignant progression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320515/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320515/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Kai -- Diskin, Sharon J -- Zhang, Haitao -- Attiyeh, Edward F -- Winter, Cynthia -- Hou, Cuiping -- Schnepp, Robert W -- Diamond, Maura -- Bosse, Kristopher -- Mayes, Patrick A -- Glessner, Joseph -- Kim, Cecilia -- Frackelton, Edward -- Garris, Maria -- Wang, Qun -- Glaberson, Wendy -- Chiavacci, Rosetta -- Nguyen, Le -- Jagannathan, Jayanti -- Saeki, Norihisa -- Sasaki, Hiroki -- Grant, Struan F A -- Iolascon, Achille -- Mosse, Yael P -- Cole, Kristina A -- Li, Hongzhe -- Devoto, Marcella -- McGrady, Patrick W -- London, Wendy B -- Capasso, Mario -- Rahman, Nazneen -- Hakonarson, Hakon -- Maris, John M -- 9024/Cancer Research UK/United Kingdom -- R00 CA151869/CA/NCI NIH HHS/ -- R01 CA124709/CA/NCI NIH HHS/ -- R01 CA124709-05/CA/NCI NIH HHS/ -- R01-CA124709/CA/NCI NIH HHS/ -- U10-CA98413/CA/NCI NIH HHS/ -- U10-CA98543/CA/NCI NIH HHS/ -- UL1-RR024134-03/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Jan 13;469(7329):216-20. doi: 10.1038/nature09609.

    Multilevel amplified spontaneous emission in I2 (1993)

    Notes: We report the results of a study of amplified spontaneous emission (ASE) in the I2(B→X) system. For many (v',v‘) bands, several J'→J‘ transitions contribute to the ASE in a cooperative manner. We present spectroscopic and kinetic data that contrast this cooperative stimulated emission to the emission in previously reported optically pumped lasers. Transitions that involve several cooperatively emitting levels produce efficient conversion of the pump laser to near-infrared output.

    Topics: Physics
    Notes: ArF(B-X) laser emission has been observed under long pulse electron-beam excitation at relatively low pump rate. ArF lasing only occurred with Ne buffered gas mixtures. Optimum performance of 1.93 J/l at an intrinsic efficiency of 1.35% occurred with an Ar/F2 mixture of 1/0.075% using a Ne buffer to 4.0 amagats. Total energy of 290 mJ in a 2-cm2 beam with a 1.0-μs full width at half maximum pulse width was recorded.

    Multilevel cooperative amplified spontaneous emission from the I2(B→X) system (1987)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Amplified spontaneous emission (ASE) on the I2(B→X) system has been studied as a function of excitation wavelength by using a narrow-band pulsed dye-laser pump source. ASE output in the range 1.1–1.3 μm has been observed for dye-laser excitation wavelengths between 515 and 600 nm. Cooperative emission from several adjacent rotational levels has been observed and provides an explanation for anomalous spectral features. The conversion efficiency of dye-laser photons to ASE output was as high as a few percent. Pump energy thresholds as low as 5.0 μJ were observed.
