The semi-arid Central Andes are characterized by dry summers, with precipitation close to zero, low relative humidity and intense solar radiation. We show that katabatic forcing is dominant both on the glacier tongue and in the fore field, and that low humidity and absence of clouds cause strong radiative cooling of the glacier surface. Surface albedo is basically constant for snow and ice, because of the scarcity of solid precipitation. The energy balance of the glacier is simulated for a 2-month period in austral summer using two models of different complexity, which differ in the inclusion of the heat conduction flux into the snowpack and in the parameterization of the incoming longwave radiation. Net shortwave radiation is the dominant component of the energy balance. The sensible heat flux is always positive, while both the net longwave radiation and latent heat flux are negative. Neglecting the subsurface heat flux and corresponding variations in surface temperature leads to an overestimation of ablation of 2% over a total of 3695 mm water equivalent (w.e.) at the end of the season. Correct modelling of incoming longwave radiation is crucial, and we suggest that parameterizations based on vapour pressure and air temperature should be used rather than on computed cloud amount. We also used an enhanced temperature-index model incorporating the shortwave radiation flux, which has two empirical parameters. We apply it both with values of parameters obtained for Alpine glaciers and recalibrated on Juncal Norte. The model recalibrated against the correct energy balance simulations performs very well. The model parameters respond to the meteorological conditions typical of this climatic setting.","lang":"eng"}],"publication_status":"published","volume":22,"quality_controlled":"1","extern":"1","page":"3980-3997","date_published":"2008-09-15T00:00:00Z","publisher":"Wiley","intvolume":"        22","scopus_import":"1","title":"A study of the energy balance and melt regime on Juncal Norte Glacier, semi-arid Andes of central Chile, using melt models of different complexity","article_processing_charge":"No","issue":"19","date_updated":"2023-02-20T08:48:33Z","publication":"Hydrological Processes","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","day":"15","month":"09","publication_identifier":{"issn":["0885-6087"],"eissn":["1099-1085"]},"author":[{"first_name":"Francesca","full_name":"Pellicciotti, Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","last_name":"Pellicciotti"},{"last_name":"Helbing","full_name":"Helbing, Jakob","first_name":"Jakob"},{"full_name":"Rivera, Andrés","first_name":"Andrés","last_name":"Rivera"},{"last_name":"Favier","full_name":"Favier, Vincent","first_name":"Vincent"},{"last_name":"Corripio","full_name":"Corripio, Javier","first_name":"Javier"},{"last_name":"Araos","first_name":"José","full_name":"Araos, José"},{"full_name":"Sicart, Jean-Emmanuel","first_name":"Jean-Emmanuel","last_name":"Sicart"},{"last_name":"Carenzo","first_name":"Marco","full_name":"Carenzo, Marco"}],"type":"journal_article","status":"public"},{"month":"03","abstract":[{"text":"The crystalline-like structure of the optic lobes of the fruit fly Drosophila melanogaster has made them a model system for the study of neuronal cell-fate determination, axonal path finding, and target selection. For functional studies, however, the small size of the constituting visual interneurons has so far presented a formidable barrier. We have overcome this problem by establishing in vivo whole-cell recordings [1] from genetically targeted visual interneurons of Drosophila. Here, we describe the response properties of six motion-sensitive large-field neurons in the lobula plate that form a network consisting of individually identifiable, directionally selective cells most sensitive to vertical image motion (VS cells [2, 3]). Individual VS cell responses to visual motion stimuli exhibit all the characteristics that are indicative of presynaptic input from elementary motion detectors of the correlation type [4, 5]. Different VS cells possess distinct receptive fields that are arranged sequentially along the eye's azimuth, corresponding to their characteristic cellular morphology and position within the retinotopically organized lobula plate. In addition, lateral connections between individual VS cells cause strongly overlapping receptive fields that are wider than expected from their dendritic input. Our results suggest that motion vision in different dipteran fly species is accomplished in similar circuitries and according to common algorithmic rules. The underlying neural mechanisms of population coding within the VS cell network and of elementary motion detection, respectively, can now be analyzed by the combination of electrophysiology and genetic intervention in Drosophila.","lang":"eng"}],"day":"11","publication_status":"published","author":[{"full_name":"Maximilian Jösch","first_name":"Maximilian A","last_name":"Jösch","id":"2BD278E6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3937-1330"},{"last_name":"Plett","first_name":"Johannes","full_name":"Plett, Johannes"},{"last_name":"Borst","full_name":"Borst, Alexander","first_name":"Alexander"},{"last_name":"Reiff","first_name":"Dierk","full_name":"Reiff, Dierk F"}],"date_published":"2008-03-11T00:00:00Z","status":"public","type":"journal_article","publisher":"Cell Press","quality_controlled":0,"volume":18,"page":"368 - 374","extern":1,"intvolume":"        18","year":"2008","issue":"5","date_updated":"2021-01-12T06:49:42Z","acknowledgement":"This work was supported by the Max-Planck-Society and by a Human Frontier Science Program (HFSP) grant to K.

In particular, CpG context elevates the mutation rate by an order of magnitude. Mutations also vary widely in their effect on the molecular function, phenotype, and fitness. Independence of the probability of occurrence of a new mutation's effect has been a fundamental premise in genetics. However, highly mutable contexts may be preserved by negative selection at important sites but destroyed by mutation at sites under no selection. Thus, there may be a positive correlation between the rate of mutations at a nucleotide site and the magnitude of their effect on fitness. We studied the impact of CpG context on the rate of human-chimpanzee divergence and on intrahuman nucleotide diversity at non-synonymous coding sites. We compared nucleotides that occupy identical positions within codons of identical amino acids and only differ by being within versus outside CpG context. Nucleotides within CpG context are under a stronger negative selection, as revealed by their lower, proportionally to the mutation rate, rate of evolution and nucleotide diversity. In particular, the probability of fixation of a non-synonymous transition at a CpG site is two times lower than at a CpG site. Thus, sites with different mutation rates are not necessarily selectively equivalent. This suggests that the mutation rate may complement sequence conservation as a characteristic predictive of functional importance of nucleotide sites.","lang":"eng"}],"_id":"844","publication":"PLoS Genetics","doi":"10.1371/journal.pgen.1000281","acknowledgement":"This work was supported in part by NIH grants R01 GM078598 and U54 LM008748.","date_updated":"2021-01-12T08:19:16Z","issue":"11","year":"2008","citation":{"ama":"Schmidt S, Gerasimova A, Kondrashov F, Adzuhbei I, Kondrashov A, Sunyaev S.

Recent NMR relaxation dispersion studies revealed the presence of a low-populated (excited) state of KIX that exists in equilibrium with the natively folded form under non-denaturing conditions, and likely represents the equilibrium analog of the folding intermediate. Here, we combine amide hydrogen/deuterium exchange measurements using rapid NMR data acquisition techniques with backbone 15N and 13C relaxation dispersion experiments to further investigate the equilibrium folding of the KIX domain. Residual structure within the folding intermediate is detected by both methods, and their combination enables reliable quantification of the amount of persistent residual structure. Three well-defined folding subunits are found, which display variable stability and correspond closely to the individual helices in the native state. While two of the three helices (α2 and α3) are partially formed in the folding intermediate (to ∼ 50% and ∼ 80%, respectively, at 20 °C), the third helix is disordered. The observed helical content within the excited state exceeds the helical propensities predicted for the corresponding peptide regions, suggesting that the two helices are weakly mutually stabilized, while methyl 13C relaxation dispersion data indicate that a defined packing arrangement is unlikely. Temperature-dependent experiments reveal that the largest enthalpy and entropy changes along the folding reaction occur during the final transition from the intermediate to the native state. Our experimental data are consistent with a folding mechanism where helices α2 and α3 form rapidly, although to different extents, while helix α1 consolidates only as folding proceeds to complete the native state-structure."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","day":"18","month":"07","publication_identifier":{"issn":["0022-2836"]},"author":[{"full_name":"Schanda, Paul","first_name":"Paul","last_name":"Schanda","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","orcid":"0000-0002-9350-7606"},{"last_name":"Brutscher","full_name":"Brutscher, Bernhard","first_name":"Bernhard"},{"first_name":"Robert","full_name":"Konrat, Robert","last_name":"Konrat"},{"last_name":"Tollinger","first_name":"Martin","full_name":"Tollinger, Martin"}],"publication_status":"published","doi":"10.1016/j.jmb.2008.05.040","publication":"Journal of Molecular Biology","language":[{"iso":"eng"}],"_id":"8480","article_type":"original","intvolume":"       380","keyword":["Molecular Biology"],"title":"Folding of the KIX domain: Characterization of the equilibrium analog of a folding intermediate using 15N/13C relaxation dispersion and fast 1H/2H amide exchange NMR spectroscopy","date_created":"2020-09-18T10:12:29Z","citation":{"chicago":"Schanda, Paul, Bernhard Brutscher, Robert Konrat, and Martin Tollinger. “Folding of the KIX Domain: Characterization of the Equilibrium Analog of a Folding Intermediate Using 15N/13C Relaxation Dispersion and Fast 1H/2H Amide Exchange NMR Spectroscopy.” <i>Journal of Molecular Biology</i>.

The expression of the corresponding periplasmic CopK protein is strongly upregulated in the presence of copper, leading to a high periplasmic accumulation. The structure and metal-binding properties of CopK were investigated by NMR and mass spectrometry. The protein is dimeric in the apo state with a dissociation constant in the range of 10- 5 M estimated from analytical ultracentrifugation. Mass spectrometry revealed that CopK has two high-affinity Cu(I)-binding sites per monomer with different Cu(I) affinities. Binding of Cu(II) was observed but appeared to be non-specific. The solution structure of apo-CopK revealed an all-β fold formed of two β-sheets in perpendicular orientation with an unstructured C-terminal tail. The dimer interface is formed by the surface of the C-terminal β-sheet. Binding of the first Cu(I)-ion induces a major structural modification involving dissociation of the dimeric apo-protein. Backbone chemical shifts determined for the 1Cu(I)-bound form confirm the conservation of the N-terminal β-sheet, while the last strand of the C-terminal sheet appears in slow conformational exchange. We hypothesize that the partial disruption of the C-terminal β-sheet is related to dimer dissociation. NH-exchange data acquired on the apo-protein are consistent with a lower thermodynamic stability of the C-terminal sheet. CopK contains seven methionine residues, five of which appear highly conserved. Chemical shift data suggest implication of two or three methionines (Met54, Met38, Met28) in the first Cu(I) site. Addition of a second Cu(I) ion further increases protein plasticity. Comparison of the structural and metal-binding properties of CopK with other periplasmic copper-binding proteins reveals two conserved features within these functionally related proteins: the all-β fold and the methionine-rich Cu(I)-binding site.","lang":"eng"}],"day":"04","oa_version":"None","status":"public","date_published":"2008-07-04T00:00:00Z","type":"journal_article","publisher":"Elsevier","quality_controlled":"1","volume":380,"page":"386-403","extern":"1","issue":"2","article_processing_charge":"No","year":"2008","date_updated":"2021-01-12T08:19:34Z","keyword":["Molecular Biology"],"title":"Molecular structure and metal-binding properties of the periplasmic CopK protein expressed in Cupriavidus metallidurans CH34 during copper challenge","citation":{"apa":"Bersch, B., Favier, A., Schanda, P., van Aelst, S., Vallaeys, T., Covès, J., … Wattiez, R.

To achieve the highest possible sensitivity, SOFAST-HMQC experiments are preferably performed on high-field NMR spectrometers equipped with cryogenically cooled probes. The duty cycle of over 80% in fast-pulsing SOFAST-HMQC experiments, however, may cause problems when using a cryogenic probe. Here we introduce SE-IPAP-SOFAST-HMQC, a new pulse sequence that provides comparable sensitivity to standard SOFAST-HMQC, while avoiding heteronuclear decoupling during 1H detection, and thus significantly reducing the radiofrequency load of the probe during the experiment. The experiment is also attractive for fast and sensitive measurement of heteronuclear one-bond spin coupling constants.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","oa_version":"None","author":[{"last_name":"Kern","first_name":"Thomas","full_name":"Kern, Thomas"},{"orcid":"0000-0002-9350-7606","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","last_name":"Schanda","first_name":"Paul","full_name":"Schanda, Paul"},{"last_name":"Brutscher","first_name":"Bernhard","full_name":"Brutscher, Bernhard"}],"publication_status":"published","publication":"Journal of Magnetic Resonance","doi":"10.1016/j.jmr.2007.11.015","_id":"8482","article_type":"letter_note","language":[{"iso":"eng"}],"intvolume":"       190","issue":"2","year":"2008","article_processing_charge":"No","date_updated":"2021-01-12T08:19:35Z","keyword":["Nuclear and High Energy Physics","Biophysics","Biochemistry","Condensed Matter Physics"],"title":"Sensitivity-enhanced IPAP-SOFAST-HMQC for fast-pulsing 2D NMR with reduced radiofrequency load","citation":{"apa":"Kern, T., Schanda, P., &#38; Brutscher, B.

The arginine vasopressin V1a receptor (V1aR) modulates social cognition and behavior in a wide variety of species. Variation in a repetitive microsatellite element in the 5′ flanking region of the V1aR gene (AVPR1A) in rodents has been associated with variation in brain V1aR expression and in social behavior. In humans, the 5′ flanking region of AVPR1A contains a tandem duplication of two ∼350 bp, microsatellite-containing elements located approximately 3.5 kb upstream of the transcription start site. The first block, referred to as DupA, contains a polymorphic (GT) 25microsatellite; the second block, DupB, has a complex (CT) 4-(TT)-(CT)8-(GT)24polymorphic motif, known as RS3. Polymorphisms in RS3 have been associated with variation in sociobehavioral traits in humans, including autism spectrum disorders. Thus, evolution of these regions may have contributed to variation in social behavior in primates. We examined the structure of these regions in six ape, six monkey, and one prosimian species. Results. Both tandem repeat blocks are present upstream of the AVPR1A coding region in five of the ape species we investigated, while monkeys have only one copy of this region. As in humans, the microsatellites within DupA and DupB are polymorphic in many primate species. Furthermore, both single (lacking DupB) and duplicated alleles (containing both DupA and DupB) are present in chimpanzee (Pan troglodytes) populations with allele frequencies of 0.795 and 0.205 for the single and duplicated alleles, respectively, based on the analysis of 47 wild-caught individuals. Finally, a phylogenetic reconstruction suggests two alternate evolutionary histories for this locus. Conclusion. There is no obvious relationship between the presence of the RS3 duplication and social organization in primates. However, polymorphisms identified in some species may be useful in future genetic association studies. In particular, the presence of both single and duplicated alleles in chimpanzees provides a unique opportunity to assess the functional role of this duplication in contributing to variation in social behavior in primates. While our initial studies show no signs of directional selection on this locus in chimps, pharmacological and genetic association studies support a potential role for this region in influencing V1aR expression and social behavior."}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"month":"01","author":[{"first_name":"Zoe","full_name":"Donaldson, Zoe R","last_name":"Donaldson"},{"orcid":"0000-0001-8243-4694","last_name":"Kondrashov","id":"44FDEF62-F248-11E8-B48F-1D18A9856A87","first_name":"Fyodor","full_name":"Fyodor Kondrashov"},{"last_name":"Putnam","full_name":"Putnam, Andrea S","first_name":"Andrea"},{"last_name":"Bai","first_name":"Yaohui","full_name":"Bai, Yaohui"},{"last_name":"Stoinski","full_name":"Stoinski, Tara S","first_name":"Tara"},{"first_name":"Elizabeth","full_name":"Hammock, Elizabeth A","last_name":"Hammock"},{"last_name":"Young","full_name":"Young, Larry","first_name":"Larry"}],"publication_status":"published","doi":"10.1186/1471-2148-8-180","publication":"BMC Evolutionary Biology","_id":"895","intvolume":"         8","citation":{"short":"Z.

The GDL plays an important role for electrochemical losses due to gas transport limitations at high current densities. Characterization and optimization of these layers is therefore essential to improve power density. A recently developed method which allows for fast diffusimetry is applied and data compared to the literature values. Measurements are made as a function of direction and compression and the effect of different binder structures and hydrophobic treatments on effective diffusivities are discussed. A better understanding of the results is gained by including novel GDL cross-section images and a meaningful unit cell model for the interpretation of the data. The diffusivity data is valuable for GDL manufacturers and future PEFC models. The study reveals that a binder–fiber ratio larger than 50% has a negative impact on the effective diffusion properties. The hydrophobic treatment which is necessary to improve the water management can impede diffusion and thus reduce the power density.

A specialized two-cell stack with advanced localized diagnostics was developed and used to analyze the mechanism and effect of cell-to-cell coupling as a result of operationally relevant variations in reactant feed flow. Contributions to overall and local voltage changes with respect to uniformly operated cells are scrutinized. Unequal operation of the cells causes in-plane current in the bipolar plate to redistribute current and result in inhomogeneous polarization. Both increasing and decreasing polarization along the air-flow path reduces cell power as compared to isopotential operation. A two-dimensional model based on a commercial computational fluid dynamics code is used to back and extend the experimental results to more general cases. Furthermore, the experimental setup presented allowed for the first time to perform simultaneous localized electrochemical impedance spectroscopy beyond the single-cell level. The mechanism of mutual cell interaction on local and integral spectra is revealed. Results show that virtually identical operation of the cells is essential to obtain meaningful integral spectra.","lang":"eng"}],"publisher":"The Electrochemical Society","type":"journal_article","status":"public","date_published":"2008-05-08T00:00:00Z","extern":"1","quality_controlled":"1","volume":155,"date_updated":"2021-01-12T08:13:03Z","article_processing_charge":"No","issue":"7","year":"2008","citation":{"apa":"Freunberger, S.

Beside ensuring sufficient electrical and thermal contact between the whole electrode area and the flow field, these typically 200–400 μm thick porous structures enable the access of educts to the electrode area which would be occluded by the flow field lands if the flow field is directly attached to the electrode. Hence, the characterisation of properties pertaining to mass transport of educts and products through these structures is indispensable whilst examining the contribution of the GDLs to the overall electrochemical characteristics of a MEA. A fast and cost effective method to measure the effective diffusivity of a GDL is presented. Electrochemical impedance spectroscopy is applied to measure the effective ionic conductivity of an electrolyte-soaked GDL. Taking advantage of the analogy between Ficks and Ohms law, this provides a measure for the effective diffusivity. The method is described in detail, including experimental as well as theoretical aspects, and selected results, highlighting the anisotropy and dependence on the degree of compression, are shown. Moreover, a two-dimensional model consisting of regularly spaced ellipses is developed to represent the porous structure of the GDL, and by using conformal maps, the agreement between this model and experiment with respect to the sensitivity of the effective diffusivity towards compression is shown."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"7322","article_type":"original","language":[{"iso":"eng"}],"publication":"Journal of Electroanalytical Chemistry","doi":"10.1016/j.jelechem.2007.09.014","date_updated":"2021-01-12T08:13:03Z","issue":"1","article_processing_charge":"No","year":"2008","title":"Electrochemical diffusimetry of fuel cell gas diffusion layers","date_created":"2020-01-15T12:21:57Z","citation":{"ama":"Kramer D, Freunberger SA, Flückiger R, et al.

Both are controlled by morphogens, which activate target genes in the growing tissue in a concentration-dependent manner. Thus the morphogen model is an intrinsically quantitative concept. However, quantitative studies were performed only in recent years on two morphogens: Bicoid and Decapentaplegic. This review covers quantitative aspects of the formation and precision of the Decapentaplegic morphogen gradient. The morphogen gradient concept is transitioning from a soft definition to a precise idea of what the gradient could really do."}],"day":"01","month":"04"},{"intvolume":"        10","citation":{"apa":"Bittig, T., Wartlick, O., Kicheva, A., González Gaitárr, M., &#38; Julicher, F.

Here we show that nanoscale grooves can control the nucleation of epitaxial Ge islands on Si(001), and can drive lateral motion of existing islands onto the grooves, even when the grooves are very narrow and shallow compared to the islands. A position centered on the groove minimizes energy. We use as prototype grooves the trenches which form naturally around islands. During coarsening, the shrinking islands move laterally to sit directly astride that trench.
