The combination of cobalt(III) acetylacetonate and lithium bis(trimethylsilyl)amide was subjected to further process intensification at 200 °C (15 bar), allowing a significant reduction of the catalyst/base loading and a dramatic increase in catalytic efficiency (turnover frequency) by a factor of 1000 compared to traditional protocols. The high-throughput screening additionally identified novel nickel- and copper-based metal/ligand combinations that favored an amination pathway competing with C-H activation, with the addition of ligands, such as 1,10-phenanthroline, having a profound influence on the selectivity.

We use the physically based, spatially distributed hydrological model TOPKAPI to study the exchange between glaciers and climate in the upper Aconcagua River Basin during the summer season and identify the model parameters that are robust and transferable and those that are more dependent on calibration. TOPKAPI has recently been adapted to incorporate an enhanced temperature index approach for snow and ice melting. We suggest a calibration procedure that allows calibration of parameters in three steps by separating parameters governing distinct processes. We evaluate the parameters' transferability in time and in space by applying the model at two spatial scales. TOPKAPI's ability to simulate the relevant processes is tested against meteorological, ablation, and glacier runoff data measured on Juncal Norte Glacier during two glacier ablation seasons. The model was applied successfully to the climatic setting of the Dry Andes once its parameters were recalibrated. We found a clear distinction between parameters that are stable in time and those that need recalibration. The parameters of the melt model are transferable from one season to the other, while the parameters governing the extrapolation of meteorological input data and the routing of glacier meltwater need recalibration from one season to the other. Sensitivity analysis revealed that the model is most sensitive to the temperature lapse rate governing the extrapolation of air temperature from point measurements to the glacier scale and to the melt parameter that multiplies the shortwave radiation balance."}],"issue":"3","volume":48,"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0043-1397"]},"publication_status":"published","status":"public","type":"journal_article","article_type":"original","_id":"12644","extern":"1","date_updated":"2023-02-21T09:38:36Z","quality_controlled":"1","publisher":"American Geophysical Union","oa":1,"doi":"10.1029/2011wr010559","date_published":"2012-03-01T00:00:00Z","date_created":"2023-02-20T08:17:39Z","day":"01","publication":"Water Resources Research","year":"2012","article_number":"W03509","title":"Calibration of a physically based, spatially distributed hydrological model in a glacierized basin: On the use of knowledge from glaciometeorological processes to constrain model parameters","author":[{"last_name":"Ragettli","full_name":"Ragettli, S.","first_name":"S."},{"id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","first_name":"Francesca","full_name":"Pellicciotti, Francesca","last_name":"Pellicciotti"}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Ragettli, S., and Francesca Pellicciotti. “Calibration of a Physically Based, Spatially Distributed Hydrological Model in a Glacierized Basin: On the Use of Knowledge from Glaciometeorological Processes to Constrain Model Parameters.” Water Resources Research.

The scarcity of data, however, prevents the application of standard approaches that are based on data-driven models. The Hindu Kush–Karakoram–Himalaya mountain range is a crucial area in terms of water resources, but our understanding of the response of its high-elevation catchments to a changing climate is hindered by lack of hydro-meteorological and cryospheric data. Hydrological modeling is challenging here because internal inconsistencies—such as an underestimation of precipitation input that can be compensated for by an overestimation of meltwater—might be hidden due to the complexity of feedback mechanisms that govern melt and runoff generation in such basins. Data scarcity adds to this difficulty by preventing the application of systematic calibration procedures that would allow identification of the parameter set that could guarantee internal consistency in the simulation of the single hydrological components. In this work, we use simulations from the Hunza River Basin in the Karakoram region obtained with the hydrological model TOPKAPI to quantify the predictive power of discharge and snow-cover data sets, as well as the combination of both. We also show that short-term measurements of meteorological variables such as radiative fluxes, wind speed, relative humidity, and air temperature from glacio-meteorological experiments are crucial for a correct parameterization of surface melt processes. They enable detailed simulations of the energy fluxes governing glacier–atmosphere interaction and the resulting ablation through energy-balance modeling. These simulations are used to derive calibrated parameters for the simplified snow and glacier routines in TOPKAPI. We demonstrate that such parameters are stable in space and time in similar climatic regions, thus reducing the number of parameters requiring calibration.","lang":"eng"}],"month":"02","intvolume":" 32","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1659/MRD-JOURNAL-D-11-00092.1"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1994-7151"],"issn":["0276-4741"]},"publication_status":"published","volume":32,"issue":"1","_id":"12646","status":"public","article_type":"original","type":"journal_article","extern":"1","date_updated":"2023-02-21T09:31:54Z"},{"volume":32,"issue":"1","publication_status":"published","publication_identifier":{"eissn":["1994-7151"],"issn":["0276-4741"]},"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1659/MRD-JOURNAL-D-11-00097.1"}],"scopus_import":"1","intvolume":" 32","month":"02","abstract":[{"lang":"eng","text":"Accurate quantification of the spatial distribution of precipitation in mountain regions is crucial for assessments of water resources and for the understanding of high-altitude hydrology, yet it is one of the largest unknowns due to the lack of high-altitude observations. The Hunza basin in Pakistan contains very large glacier systems, which, given the melt, cannot persist unless precipitation (snow input) is much higher than what is observed at the meteorological stations, mostly located in mountain valleys. Several studies, therefore, suggest strong positive vertical precipitation lapse rates; in the present study, we quantify this lapse rate by using glaciers as a proxy. We assume a neutral mass balance for the glaciers for the period from 2001 to 2003, and we inversely model the precipitation lapse by balancing the total accumulation in the catchment area and the ablation over the glacier area for the 50 largest glacier systems in the Hunza basin in the Karakoram. Our results reveal a vertical precipitation lapse rate that equals 0.21 ± 0.12% m−1, with a maximum precipitation at an elevation of 5500 masl. We showed that the total annual basin precipitation (828 mm) is 260% higher than what is estimated based on interpolated observations (319 mm); this has major consequences for hydrological modeling and water resource assessments in general. Our results were validated by using previously published studies on individual glaciers as well as the water balance of the Hunza basin. The approach is more widely applicable in mountain ranges where precipitation measurements at high altitude are lacking."}],"oa_version":"Published Version","date_updated":"2023-02-21T08:56:29Z","extern":"1","type":"journal_article","article_type":"original","keyword":["General Environmental Science","Development","Environmental Chemistry"],"status":"public","_id":"12647","page":"30-38","date_created":"2023-02-20T08:17:52Z","date_published":"2012-02-01T00:00:00Z","doi":"10.1659/mrd-journal-d-11-00097.1","year":"2012","publication":"Mountain Research and Development","day":"01","oa":1,"publisher":"International Mountain Society","quality_controlled":"1","article_processing_charge":"No","author":[{"last_name":"Immerzeel","full_name":"Immerzeel, Walter Willem","first_name":"Walter Willem"},{"full_name":"Pellicciotti, Francesca","last_name":"Pellicciotti","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","first_name":"Francesca"},{"first_name":"Arun B.","last_name":"Shrestha","full_name":"Shrestha, Arun B."}],"title":"Glaciers as a proxy to quantify the spatial distribution of precipitation in the Hunza basin","citation":{"ista":"Immerzeel WW, Pellicciotti F, Shrestha AB. 2012.

In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates. In this paper, an existing physically based point model for the ablation of debris-covered ice is incorporated in a distributed melt model and applied to Haut Glacier d'Arolla, Switzerland, which has three large patches of debris cover on its surface. The model is based on a 10 m resolution digital elevation model (DEM) of the area; each glacier pixel in the DEM is defined as either bare or debris-covered ice, and may be covered in snow that must be melted off before ice ablation is assumed to occur. Each debris-covered pixel is assigned a debris thickness value using probability distributions based on over 1000 manual thickness measurements. Locally observed meteorological data are used to run energy balance calculations in every pixel, using an approach suitable for snow, bare ice or debris-covered ice as appropriate. The use of the debris model significantly reduces the total ablation in the debris-covered areas, however the precise reduction is sensitive to the temperature extrapolation used in the model distribution because air near the debris surface tends to be slightly warmer than over bare ice. Overall results suggest that the debris patches, which cover 10% of the glacierized area, reduce total runoff from the glacierized part of the basin by up to 7%.","lang":"eng"}],"month":"09","intvolume":" 117","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.1029/2012JD017795","open_access":"1"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0148-0227"]},"publication_status":"published","volume":117,"issue":"D18"},{"status":"public","conference":{"name":"FSE: Foundations of Software Engineering","start_date":"2012-11-11","location":"Cary, NC, USA","end_date":"2012-11-16"},"type":"conference","_id":"1384","department":[{"_id":"ToHe"}],"date_updated":"2021-01-12T06:50:18Z","month":"11","main_file_link":[{"url":"http://arxiv.org/abs/1109.6926","open_access":"1"}],"scopus_import":1,"oa_version":"Preprint","abstract":[{"lang":"eng","text":"Software model checking, as an undecidable problem, has three possible outcomes: (1) the program satisfies the specification, (2) the program does not satisfy the specification, and (3) the model checker fails. The third outcome usually manifests itself in a space-out, time-out, or one component of the verification tool giving up; in all of these failing cases, significant computation is performed by the verification tool before the failure, but no result is reported. We propose to reformulate the model-checking problem as follows, in order to have the verification tool report a summary of the performed work even in case of failure: given a program and a specification, the model checker returns a condition Ψ - usually a state predicate - such that the program satisfies the specification under the condition Ψ - that is, as long as the program does not leave the states in which Ψ is satisfied. In our experiments, we investigated as one major application of conditional model checking the sequential combination of model checkers with information passing. We give the condition that one model checker produces, as input to a second conditional model checker, such that the verification problem for the second is restricted to the part of the state space that is not covered by the condition, i.e., the second model checker works on the problems that the first model checker could not solve. Our experiments demonstrate that repeated application of conditional model checkers, passing information from one model checker to the next, can significantly improve the verification results and performance, i.e., we can now verify programs that we could not verify before."}],"ec_funded":1,"language":[{"iso":"eng"}],"publication_status":"published","project":[{"grant_number":"267989","name":"Quantitative Reactive Modeling","call_identifier":"FP7","_id":"25EE3708-B435-11E9-9278-68D0E5697425"},{"grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"article_number":"57","title":"Conditional model checking: A technique to pass information between verifiers","author":[{"last_name":"Beyer","full_name":"Beyer, Dirk","first_name":"Dirk"},{"last_name":"Henzinger","orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A"},{"first_name":"Mehmet","last_name":"Keremoglu","full_name":"Keremoglu, Mehmet"},{"first_name":"Philipp","last_name":"Wendler","full_name":"Wendler, Philipp"}],"publist_id":"5826","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Beyer, Dirk, et al. “Conditional Model Checking: A Technique to Pass Information between Verifiers.” Proceedings of the ACM SIGSOFT 20th International Symposium on the Foundations of Software Engineering, 57, ACM, 2012, doi:10.1145/2393596.2393664.","short":"D.

","abstract":[{"text":"The spatial organization of cell fates during development involves the interpretation of morphogen gradients by cellular signaling cascades and transcriptional networks. Recent studies use biophysical models, genetics, and quantitative imaging to unravel how tissue-level morphogen behavior arises from subcellular events. Moreover, data from several systems show that morphogen gradients, downstream signaling, and the activity of cell-intrinsic transcriptional networks change dynamically during pattern formation. Studies from Drosophila and now also vertebrates suggest that transcriptional network dynamics are central to the generation of gene expression patterns. Together, this leads to the view that pattern formation is an emergent behavior that results from the coordination of events occurring across molecular, cellular, and tissue scales. The development of novel approaches to study this complex process remains a challenge.","lang":"eng"}],"intvolume":" 338","month":"10","quality_controlled":0,"publisher":"American Association for the Advancement of Science","publication":"Science","day":"12","publication_status":"published","year":"2012","date_created":"2018-12-11T11:53:40Z","date_published":"2012-10-12T00:00:00Z","volume":338,"issue":"6104","doi":"10.1126/science.1225182","page":"210 - 212","_id":"1725","status":"public","type":"journal_article","extern":1,"date_updated":"2021-01-12T06:52:47Z","citation":{"ama":"Kicheva A, Cohen M, Briscoe J.

Despite the absence of intentional doping, the first transistor-type devices made from single wires show low-resistive electrical contacts and single-hole transport at sub-Kelvin temperatures.

By varying the superconducting gap Δ with a magnetic field B we investigated the transition from strong coupling Δ≪T K to weak-coupling Δ≫T K, where T K is the Kondo temperature. Below the critical field, we observe a persisting zero-bias Kondo resonance that vanishes only for low B or higher temperatures, leaving the room to more robust subgap structures at bias voltages between Δ and 2Δ. For strong and approximately symmetric tunnel couplings, a Josephson supercurrent is observed in addition to the Kondo peak. We ascribe the coexistence of a Kondo resonance and a superconducting gap to a significant density of intragap quasiparticle states, and the finite-bias subgap structures to tunneling through Shiba states. Our results, supported by numerical calculations, own relevance also in relation to tunnel-spectroscopy experiments aiming at the observation of Majorana fermions in hybrid nanostructures."}],"acknowledgement":"This work was supported by the EU Marie Curie program and by the Agence Nationale de la Recherche.

The roles of the source/drain contacts and of the silicon channel could be independently evaluated and tuned. Wrap gates surrounding the silicide-silicon contact interfaces were proved to be effective in inducing a full suppression of the contact Schottky barriers, thereby enabling carrier injection down to liquid helium temperature. By independently tuning the effective Schottky barrier heights, a variety of reconfigurable device functionalities could be obtained. In particular, the same nanowire device could be configured to work as a Schottky barrier transistor, a Schottky diode, or a p-n diode with tunable polarities. This versatility was eventually exploited to realize a NAND logic gate with gain well above one.","lang":"eng"}],"acknowledgement":"This work was supported by the Agence Nationale de la Recherche (ANR) through the ACCESS and COHESION projects and by the European Commission through the Chemtronics program MEST-CT-2005-020513","page":"3074 - 3079","issue":"6","date_published":"2012-06-13T00:00:00Z","doi":"10.1021/nl300930m","volume":12,"date_created":"2018-12-11T11:53:50Z","publication_status":"published","year":"2012","day":"13","publication":"Nano Letters"},{"title":"Demonstrating W-type entanglement of Dicke states in resonant cavity quantum electrodynamics","author":[{"first_name":"Jonas","full_name":"Mlynek, Jonas A","last_name":"Mlynek"},{"first_name":"Abdufarrukh","full_name":"Abdumalikov, Abdufarrukh A","last_name":"Abdumalikov"},{"first_name":"Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","orcid":"0000-0001-8112-028X","full_name":"Johannes Fink"},{"last_name":"Steffen","full_name":"Steffen, L.

We use a superconducting qubit as a nonlinear probe of the phase, which is otherwise unobservable due to the linearity of the oscillator. We show that the geometric phase is, for a variety of cyclic paths, proportional to the area enclosed in the quadrature plane. At the transition to the nonadiabatic regime, we study corrections to the phase and dephasing of the qubit caused by qubit-resonator entanglement. In particular, we identify parameters for which this dephasing mechanism is negligible even in the nonadiabatic regime. The demonstrated controllability makes our system a versatile tool to study geometric phases in open quantum systems and to investigate their potential for quantum information processing.","lang":"eng"}]},{"citation":{"ieee":"C.

Here, we report the on-demand generation and characterization of Bell-type entangled states between a superconducting qubit and propagating microwave fields composed of zero-, one-, and two-photon Fock states. Using low noise linear amplification and efficient data acquisition we extract all relevant correlations between the qubit and the photon states and demonstrate entanglement with high fidelity."}],"acknowledgement":"This work was supported by the European Research Council (ERC) through a Starting Grant and by ETHZ","main_file_link":[{"open_access":"0","url":"http://arxiv.org/abs/1209.0441"}],"publisher":"American Physical Society","quality_controlled":0,"intvolume":" 109","month":"12"},{"type":"journal_article","status":"public","_id":"1801","publist_id":"5309","author":[{"id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","first_name":"Sandra","last_name":"Siegert","full_name":"Sandra Siegert","orcid":"0000-0001-8635-0877"},{"full_name":"Cabuy, Erik","last_name":"Cabuy","first_name":"Erik"},{"first_name":"Brigitte","full_name":"Scherf, Brigitte G","last_name":"Scherf"},{"first_name":"Hubertus","last_name":"Kohler","full_name":"Kohler, Hubertus"},{"full_name":"Panda, Satchidananda","last_name":"Panda","first_name":"Satchidananda"},{"first_name":"Yunzheng","last_name":"Le","full_name":"Le, Yunzheng"},{"full_name":"Fehling, Hans J","last_name":"Fehling","first_name":"Hans"},{"full_name":"Gaidatzis, Dimos","last_name":"Gaidatzis","first_name":"Dimos"},{"first_name":"Michael","last_name":"Stadler","full_name":"Stadler, Michael B"},{"last_name":"Roska","full_name":"Roska, Botond M","first_name":"Botond"}],"title":"Transcriptional code and disease map for adult retinal cell types","citation":{"ieee":"S.

It is not known how the intermingled cell types of an individual adult brain region differ in their expressed genomes. Here we describe an atlas of cell type transcriptomes in one brain region, the mouse retina. We found that each adult cell type expressed a specific set of genes, including a unique set of transcription factors, forming a 'barcode' for cell identity. Cell type transcriptomes carried enough information to categorize cells into morphological classes and types. Several genes that were specifically expressed in particular retinal circuit elements, such as inhibitory neuron types, are associated with eye diseases. The resource described here allows gene expression to be compared across adult retinal cell types, experimenting with specific transcription factors to differentiate stem or somatic cells to retinal cell types, and predicting cellular targets of newly discovered disease-associated genes."}],"acknowledgement":"The study was supported by Friedrich Miescher Institute funds, Alcon award, a National Center of Competence in Research Genetics grant, a European Research Council grant, a Swiss-Hungarian grant, and RETICIRC, TREATRUSH, SEEBETTER and OPTONEURO grants from the European Union to B.R.","page":"487 - 495","date_created":"2018-12-11T11:54:05Z","issue":"3","date_published":"2012-03-01T00:00:00Z","doi":"10.1038/nn.3032","volume":15,"year":"2012","publication_status":"published","publication":"Nature Neuroscience","day":"01"}]
