We report the magnetic and magnetothermal properties of gadolinium silicide (Gd5Si4) nanoparticles prepared by surfactant-assisted ball milling of arc melted bulk ingots of the compound. Using different milling times and speeds, a wide range of crystallite sizes (13–43 nm) could be produced and a reduction in Curie temperature (TC) from 340 K to 317 K was achieved, making these nanoparticles suitable for self-controlled magnetic hyperthermia applications. The magnetothermal effect was measured in applied AC magnetic fields of amplitude 164–239 Oe and frequencies 163–519 kHz. All particles showed magnetic heating with a strong dependence of the specific absorption rate (SAR) on the average crystallite size. The highest SAR of 3.7 W g−1 was measured for 43 nm sized nanoparticles of Gd5Si4. The high SAR and low TC, (within the therapeutic range for magnetothermal therapy) makes the Gd5Si4 behave like self-regulating heat switches that would be suitable for self-controlled magnetic hyperthermia applications after biocompatibility and cytotoxicity tests."}],"article_processing_charge":"No","article_type":"original","type":"journal_article","publication":"RSC Advances","date_updated":"2024-10-15T13:44:01Z","OA_place":"publisher","DOAJ_listed":"1","author":[{"full_name":"Nauman, Muhammad","id":"32c21954-2022-11eb-9d5f-af9f93c24e71","orcid":"0000-0002-2111-4846","first_name":"Muhammad","last_name":"Nauman"},{"last_name":"Alnasir","first_name":"Muhammad Hisham","full_name":"Alnasir, Muhammad Hisham"},{"last_name":"Hamayun","first_name":"Muhammad Asif","full_name":"Hamayun, Muhammad Asif"},{"last_name":"Wang","first_name":"YiXu","full_name":"Wang, YiXu"},{"full_name":"Shatruk, Michael","last_name":"Shatruk","first_name":"Michael"},{"full_name":"Manzoor, Sadia","last_name":"Manzoor","first_name":"Sadia"}],"user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","oa_version":"Published Version","keyword":["General Chemistry","General Chemical Engineering"],"date_created":"2021-02-02T15:51:23Z","publisher":"Royal Society of Chemistry","citation":{"short":"M.

The calculated diffusion coefficient values showed that electrode surface of LCNO and LCCO have limited efficiency for diffusion related phenomenon. The heterogeneous rate constants inferred better electrode kinetics of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V, respectively.

The ocean is modeled as one layer slab with a temporally fixed mean but spatially varying temperature. We find that the interactive SST decelerates the aggregation and that the deceleration is larger with a shallower slab, consistent with earlier studies. The surface temperature anomaly in dry regions is positive at first, thus opposing the diverging shallow circulation known to favor self‐aggregation, consistent with the slower aggregation. But surprisingly, the driest columns then have a negative SST anomaly, thus strengthening the diverging shallow circulation and favoring aggregation. This diverging circulation out of dry regions is found to be well correlated with the aggregation speed. It can be linked to a positive surface pressure anomaly (PSFC), itself the consequence of SST anomalies and boundary layer radiative cooling. The latter cools and dries the boundary layer, thus increasing PSFC anomalies through virtual effects and hydrostasy. Sensitivity experiments confirm the key role played by boundary layer radiative cooling in determining PSFC anomalies in dry regions, and thus the shallow diverging circulation and the aggregation speed."}],"extern":"1","oa":1,"OA_type":"gold","day":"01","year":"2020","volume":12,"title":"Self‐aggregation of convective clouds with interactive sea surface temperature","doi":"10.1029/2020ms002164","publication_status":"published","main_file_link":[{"url":"https://doi.org/10.1029/2020MS002164","open_access":"1"}],"_id":"9125","intvolume":" 12","issue":"11","publication_identifier":{"issn":["1942-2466","1942-2466"]},"quality_controlled":"1","date_published":"2020-11-01T00:00:00Z","month":"11","status":"public","date_created":"2021-02-15T14:06:23Z","publisher":"American Geophysical Union","citation":{"ama":"Shamekh S, Muller CJ, Duvel J ‐P., D’Andrea F.

In the tropics, it has long been observed that the isotopic compositions of rain and vapor near the surface are more depleted when the precipitation rate is high. This is called the “amount effect.” Previous studies, based on observations or models with parameterized convection, have highlighted the roles of deep convective and mesoscale downdrafts and rain evaporation. But the relative importance of these processes has never been quantified. We hypothesize that it can be quantified using an analytical model constrained by large‐eddy simulations. Results from large‐eddy simulations confirm that the classical amount effect can be simulated only if precipitation rate changes result from changes in the large‐scale circulation. We find that the main process depleting the water vapor compared to the equilibrium with the ocean is the fact that updrafts stem from areas where the water vapor is more enriched. The main process responsible for the amount effect is the fact that when the large‐scale ascent increases, isotopic vertical gradients are steeper, so that updrafts and downdrafts deplete the subcloud layer more efficiently.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"e2020MS002106","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1029/2020MS002106"}],"publication_status":"published","doi":"10.1029/2020ms002106","date_published":"2020-08-01T00:00:00Z","quality_controlled":"1","_id":"9126","issue":"8","intvolume":" 12","publication_identifier":{"issn":["1942-2466","1942-2466"]},"publisher":"American Geophysical Union","citation":{"ieee":"C.

Here, we investigate the Mediterranean region, often referred to as a climate change “hot spot”. From regional climate simulations, it is shown that although enhanced warming and drying over land is projected, the spatial pattern displays high variability. Indeed, drying is largely caused by enhanced warming over land. However, in Northern Europe, soil moisture alleviates warming induced drying by up to 50% due to humidity uptake from land. In already arid regions, the Mediterranean Sea is generally the only humidity source, and drying is only due to land warming. However, over Sahara and the Iberian Peninsula, enhanced warming over land is insufficient to explain the extreme drying. These regions are also isolated from humidity advection by heat lows, which are cyclonic circulation anomalies associated with surface heating over land. The cyclonic circulation scales with the temperature gradient between land and ocean which increases with climate change, reinforcing the cyclonic circulation over Sahara and the Iberian Peninsula, both diverting the zonal advection of humidity to the south of the Iberian Peninsula. The dynamics are therefore key in the warming and drying of the Mediterranean region, with extreme aridification over the Sahara and Iberian Peninsula. In these regions, the risk for human health due to the thermal load which accounts for air temperature and humidity is therefore projected to increase significantly with climate change at a level of extreme danger.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"78","publisher":"Springer Nature","citation":{"ama":"Drobinski P, Da Silva N, Bastin S, et al.

A theoretical scaling for precipitation extremes has been proposed and refined in the past decades, allowing to address separately the contributions from the thermodynamics, the dynamics and the microphysics. Theoretical constraints, as well as remaining uncertainties, associated with each of these three contributions to precipitation extremes, are discussed. Notably, although to leading order precipitation extremes seem to follow the thermodynamic theoretical expectation in idealized simulations, considerable uncertainty remains regarding the response of the dynamics and of the microphysics to warming, and considerable departure from this theoretical expectation is found in observations and in more realistic simulations. We also emphasize key outstanding questions, in particular the response of mesoscale convective organization to warming. Observations suggest that extreme rainfall often comes from an organized system in very moist environments. Improved understanding of the physical processes behind convective organization is needed in order to achieve accurate extreme rainfall prediction in our current, and in a warming climate.","lang":"eng"}],"article_number":"035001","language":[{"iso":"eng"}],"title":"Response of precipitation extremes to warming: What have we learned from theory and idealized cloud-resolving simulations, and what remains to be learned?","volume":15,"year":"2020","OA_type":"gold","day":"18","oa":1,"extern":"1","publication_status":"published","doi":"10.1088/1748-9326/ab7130","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1088/1748-9326/ab7130"}],"date_updated":"2024-10-15T13:49:06Z","type":"journal_article","publication":"Environmental Research Letters","article_type":"letter_note","article_processing_charge":"No","keyword":["Renewable Energy","Sustainability and the Environment","Public Health","Environmental and Occupational Health","General Environmental Science"],"oa_version":"Published Version","user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","author":[{"first_name":"Caroline J","last_name":"Muller","orcid":"0000-0001-5836-5350","id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","full_name":"Muller, Caroline J"},{"first_name":"Yukari","last_name":"Takayabu","full_name":"Takayabu, Yukari"}],"DOAJ_listed":"1","OA_place":"publisher","issue":"3","intvolume":" 15","publication_identifier":{"issn":["1748-9326"]},"_id":"9128","date_published":"2020-02-18T00:00:00Z","quality_controlled":"1","status":"public","month":"02","publisher":"IOP Publishing","citation":{"ista":"Muller CJ, Takayabu Y. 2020.

It is well known that SST gradients can spatially organize convection. Even with uniform SST, the spontaneous self-aggregation of convection is possible above a critical SST (here 295 K), arising mainly from radiative feedbacks. We investigate how a circular hot spot helps organize convection, and how self-aggregation feedbacks modulate this organization. The hot spot significantly accelerates aggregation, particularly for warmer/larger hot spots, and extends the range of SSTs for which aggregation occurs; however, at cold SST (290 K) the aggregated cluster disaggregates if we remove the hot spot. A large convective instability over the hot spot leads to stronger convection and generates a large-scale circulation which forces the subsidence drying outside the hot spot. Indeed, convection over the hot spot brings the atmosphere toward a warmer temperature. The warmer temperatures are imprinted over the whole domain by gravity waves and subsidence warming. The initial transient warming and concomitant subsidence drying suppress convection outside the hot spot, thus driving the aggregation. The hot-spot-induced large-scale circulation can enforce the aggregation even without radiative feedbacks for hot spots sufficiently large/warm. The strength of the large-scale circulation, which defines the speed of aggregation, is a function of the hot spot fractional area. At equilibrium, once the aggregation is well established, the moist convective region with upward midtropospheric motion, centered over the hot spot, has an area surprisingly independent of the hot spot size.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Atmospheric Science"],"title":"How do ocean warm anomalies favor the aggregation of deep convective clouds?","volume":77,"year":"2020","day":"01","extern":"1","page":"3733-3745","article_type":"original","status":"public","month":"11","article_processing_charge":"No","citation":{"mla":"Shamekh, Sara, et al. “How Do Ocean Warm Anomalies Favor the Aggregation of Deep Convective Clouds?” Journal of the Atmospheric Sciences, vol. 77, no. 11, American Meteorological Society, 2020, pp. 3733–45, doi:10.1175/jas-d-18-0369.1.","short":"S.

First, we aim at developing a simple model as an interpretative framework for the water vapor isotopic variations in the tropical troposphere over the ocean. We use large-eddy simulations to justify the underlying assumptions of this simple model, to constrain its input parameters and to evaluate its results. Second, we aim at interpreting the depletion of the water vapor isotopic composition in the lower and mid-troposphere as precipitation increases, which is a salient feature in tropical oceanic observations. This feature constitutes a stringent test on the relevance of our interpretative framework. Previous studies, based on observations or on models with parameterized convection, have highlighted the roles of deep convective and meso-scale downdrafts, rain evaporation, rain-vapor diffusive exchanges and mixing processes. The interpretative framework that we develop is a two-column model representing the net ascent in clouds and the net descent in the environment. We show that the mechanisms for depleting the troposphere when precipitation rate increases all stem from the higher tropospheric relative humidity. First, when the relative humidity is larger, less snow sublimates before melting and a smaller fraction of rain evaporates. Both effects lead to more depleted rain evaporation and eventually more depleted water vapor. This mechanism dominates in regimes of large-scale ascent. Second, the entrainment of dry air into clouds reduces the vertical isotopic gradient and limits the depletion of tropospheric water vapor.

Microfluidic networks of closed pathways pose the challenge of determining the shortest exit pathway, which involves the proper local decision-making at each bifurcating junction. Here, we focus on the basic decision faced at a T-junction by a microscopic particle, which orients among possible paths via its sensing of a diffusible substance's concentration. We study experimentally the navigation of colloidal particles following concentration gradients by diffusiophoresis. We treat the situation as a mean first passage time (MFPT) problem that unveils the important role of a separatrix in the concentration field to determine the statistics of path taking. Further, we use numerical experiments to study different strategies, including biomimetic ones such as run and tumble or Markovian chemotactic migration. The discontinuity in the MFPT at the junction makes it remarkably difficult for microscopic agents to follow the shortest path, irrespective of adopted navigation strategy. In contrast, increasing the size of the sensing agents improves the efficiency of short-path taking by harvesting information on a larger scale. It inspires the development of a run-and-whirl dynamics that takes advantage of the mathematical properties of harmonic functions to emulate particles beyond their own size.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"104202","article_type":"original","article_processing_charge":"No","date_updated":"2023-02-23T13:50:55Z","publication":"Physical Review Fluids","type":"journal_article","ddc":["530"],"scopus_import":"1"},{"date_published":"2020-06-01T00:00:00Z","quality_controlled":"1","_id":"9164","publication_identifier":{"issn":["1367-2630"]},"issue":"6","intvolume":" 22","publisher":"IOP Publishing","citation":{"mla":"Speck, Thomas, et al. “Focus on Active Colloids and Nanoparticles.” New Journal of Physics, vol. 22, no. 6, 060201, IOP Publishing, 2020, doi:10.1088/1367-2630/ab90d9.","short":"T.

Optical photons, unlike microwave photons, can be transmitted by fiber, making them suitable for long distance quantum communication. Moreover, the optical domain offers access to a large set of very well‐developed quantum optical tools, such as highly efficient single‐photon detectors and long‐lived quantum memories. For a high fidelity microwave to optical transducer, efficient conversion at single photon level and low added noise is needed. Currently, the most promising approaches to build such systems are based on second‐order nonlinear phenomena such as optomechanical and electro‐optic interactions. Alternative approaches, although not yet as efficient, include magneto‐optical coupling and schemes based on isolated quantum systems like atoms, ions, or quantum dots. Herein, the necessary theoretical foundations for the most important microwave‐to‐optical conversion experiments are provided, their implementations are described, and the current limitations and future prospects are discussed."}],"day":"01","oa":1,"volume":3,"title":"Coherent conversion between microwave and optical photons - An overview of physical implementations","year":"2020","doi":"10.1002/qute.201900077","publication_status":"published","file_date_updated":"2021-03-02T12:30:03Z"},{"keyword":["General Mathematics"],"oa_version":"Preprint","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","isi":1,"author":[{"first_name":"Sebastian","last_name":"Hensel","id":"4D23B7DA-F248-11E8-B48F-1D18A9856A87","full_name":"Hensel, Sebastian","orcid":"0000-0001-7252-8072"},{"full_name":"Rosati, Tommaso","last_name":"Rosati","first_name":"Tommaso"}],"arxiv":1,"external_id":{"arxiv":["1709.05202"],"isi":["000558100500002"]},"issue":"3","publication_identifier":{"issn":["0039-3223"],"eissn":["1730-6337"]},"intvolume":" 252","_id":"9196","quality_controlled":"1","date_published":"2020-03-01T00:00:00Z","status":"public","month":"03","page":"251-297","department":[{"_id":"JuFi"},{"_id":"GradSch"}],"date_created":"2021-02-25T08:55:03Z","citation":{"apa":"Hensel, S., & Rosati, T.

In other words, one could say that a regular function is locally modelled by the set of polynomials. The theory of regularity structures due to Hairer generalizes this observation and provides an abstract setup, which in the application to singular SPDE extends the set of polynomials by functionals constructed from, e.g., white noise. In this context, the notion of Taylor polynomials is lifted to the notion of so-called modelled distributions. The celebrated reconstruction theorem, which in turn was inspired by Gubinelli’s \\textit {sewing lemma}, is of paramount importance for the theory. It enables one to reconstruct a modelled distribution as a true distribution on Rd which is locally approximated by this extended set of models or “monomials”. In the original work of Hairer, the error is measured by means of Hölder norms. This was then generalized to the whole scale of Besov spaces by Hairer and Labbé. It is the aim of this work to adapt the analytic part of the theory of regularity structures to the scale of Triebel–Lizorkin spaces."}],"day":"01","oa":1,"volume":252,"title":"Modelled distributions of Triebel–Lizorkin type","year":"2020","doi":"10.4064/sm180411-11-2","publication_status":"published","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1709.05202"}],"scopus_import":"1","date_updated":"2025-06-24T12:07:06Z","type":"journal_article","publication":"Studia Mathematica","article_processing_charge":"No","article_type":"original"},{"acknowledgement":"This research was supported by the Austrian Science Fund (FWF) under grants S11402-N23 (RiSE/SHiNE), Z211-N23 (Wittgenstein Award), and M 2369-N33 (Meitner fellowship).","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Preprint","OA_place":"repository","external_id":{"arxiv":["1911.08360"]},"arxiv":1,"author":[{"first_name":"Guy","last_name":"Avni","orcid":"0000-0001-5588-8287","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","full_name":"Avni, Guy"},{"full_name":"Ibsen-Jensen, Rasmus","orcid":"0000-0003-4783-0389","id":"3B699956-F248-11E8-B48F-1D18A9856A87","first_name":"Rasmus","last_name":"Ibsen-Jensen"},{"first_name":"Josef","last_name":"Tkadlec","orcid":"0000-0002-1097-9684","id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87","full_name":"Tkadlec, Josef"}],"_id":"9197","publication_identifier":{"eissn":["2374-3468"],"issn":["2159-5399"],"isbn":["9781577358350"]},"intvolume":" 34","issue":"02","quality_controlled":"1","project":[{"grant_number":"S11402-N23","call_identifier":"FWF","name":"Rigorous Systems Engineering","_id":"25F2ACDE-B435-11E9-9278-68D0E5697425"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"Formal methods for the design and analysis of complex systems","call_identifier":"FWF","grant_number":"Z211"},{"_id":"264B3912-B435-11E9-9278-68D0E5697425","name":"Formal Methods meets Algorithmic Game Theory","call_identifier":"FWF","grant_number":"M02369"}],"date_published":"2020-04-03T00:00:00Z","month":"04","status":"public","page":"1798-1805","date_created":"2021-02-25T09:05:18Z","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"publisher":"Association for the Advancement of Artificial Intelligence","citation":{"chicago":"Avni, Guy, Rasmus Ibsen-Jensen, and Josef Tkadlec. “All-Pay Bidding Games on Graphs.” Proceedings of the AAAI Conference on Artificial Intelligence.

The game proceeds as follows. We place a token on some vertex in the graph and assign budgets to the two players. Each turn, each player submits a sealed legal bid (non-negative and below their remaining budget), which is deducted from their budget and the highest bidder moves the token onto an adjacent vertex. The game ends once a sink is reached, and Player 1 pays Player 2 the outcome that is associated with the sink. The players attempt to maximize their expected outcome. Our games model settings where effort (of no inherent value) needs to be invested in an ongoing and stateful manner. On the negative side, we show that even in simple games on DAGs, optimal strategies may require a distribution over bids with infinite support. A central quantity in bidding games is the ratio of the players budgets. On the positive side, we show a simple FPTAS for DAGs, that, for each budget ratio, outputs an approximation for the optimal strategy for that ratio. We also implement it, show that it performs well, and suggests interesting properties of these games. Then, given an outcome c, we show an algorithm for finding the necessary and sufficient initial ratio for guaranteeing outcome c with probability 1 and a strategy ensuring such. Finally, while the general case has not previously been studied, solving the specific game in which Player 1 wins iff he wins the first two auctions, has been long stated as an open question, which we solve.","lang":"eng"}],"oa":1,"day":"03","conference":{"end_date":"2020-02-12","location":"New York, NY, United States","name":"AAAI: Conference on Artificial Intelligence","start_date":"2020-02-07"},"OA_type":"green","year":"2020","volume":34,"title":"All-pay bidding games on graphs","doi":"10.1609/aaai.v34i02.5546","publication_status":"published","main_file_link":[{"url":"https://arxiv.org/abs/1911.08360","open_access":"1"}],"scopus_import":"1","type":"journal_article","publication":"Proceedings of the AAAI Conference on Artificial Intelligence","date_updated":"2025-07-03T11:44:58Z","article_processing_charge":"No","article_type":"original"}]
