Activation of the hypothalamic–pituitary–adrenal (HPA) axis and subsequent release of glucocorticoid hormones is a key response that mobilizes fuel stores to meet energy demands1,2,3,4,5. Despite the importance of the HPA axis response, the neural mechanisms that drive its activation during energy deficit are unknown. Here, we show that fasting-activated hypothalamic agouti-related peptide (AgRP)-expressing neurons trigger and are essential for fasting-induced HPA axis activation. AgRP neurons do so through projections to the paraventricular hypothalamus (PVH), where, in a mechanism not previously described for AgRP neurons, they presynaptically inhibit the terminals of tonically active GABAergic afferents from the bed nucleus of the stria terminalis (BNST) that otherwise restrain activity of corticotrophin-releasing hormone (CRH)-expressing neurons. This disinhibition of PVHCrh neurons requires γ-aminobutyric acid (GABA)/GABA-B receptor signalling and potently activates the HPA axis. Notably, stimulation of the HPA axis by AgRP neurons is independent of their induction of hunger, showing that these canonical ‘hunger neurons’ drive many distinctly different adaptations to the fasted state. Together, our findings identify the neural basis for fasting-induced HPA axis activation and uncover a unique means by which AgRP neurons activate downstream neurons: through presynaptic inhibition of GABAergic afferents. Given the potency of this disinhibition of tonically active BNST afferents, other activators of the HPA axis, such as psychological stress, may also work by reducing BNST inhibitory tone onto PVHCrh neurons.","lang":"eng"}],"volume":620,"page":"154-162","OA_type":"green","date_updated":"2025-07-10T11:51:40Z","intvolume":" 620","extern":"1","publisher":"Springer Nature","type":"journal_article","year":"2023","language":[{"iso":"eng"}],"day":"03","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1038/s41586-023-06358-0","publication":"Nature","quality_controlled":"1","month":"08","status":"public","author":[{"first_name":"Amelia May Barnett","full_name":"Douglass, Amelia May Barnett","orcid":"0000-0001-5398-6473","id":"de5f6fda-80fb-11ef-996f-a8c4ecd8e289","last_name":"Douglass"},{"full_name":"Resch, Jon M.","first_name":"Jon M.","last_name":"Resch"},{"last_name":"Madara","first_name":"Joseph C.","full_name":"Madara, Joseph C."},{"last_name":"Kucukdereli","first_name":"Hakan","full_name":"Kucukdereli, Hakan"},{"last_name":"Yizhar","full_name":"Yizhar, Ofer","first_name":"Ofer"},{"last_name":"Grama","full_name":"Grama, Abhinav","first_name":"Abhinav"},{"first_name":"Masahito","full_name":"Yamagata, Masahito","last_name":"Yamagata"},{"full_name":"Yang, Zongfang","first_name":"Zongfang","last_name":"Yang"},{"first_name":"Bradford B.","full_name":"Lowell, Bradford B.","last_name":"Lowell"}],"main_file_link":[{"url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC11168300/","open_access":"1"}],"issue":"7972","citation":{"ieee":"A.

Using a suite of sensitive probes of magnetism, including resonant x-ray scattering and magneto-optical polarimetry, we have discovered that ferromagnetic order onsets above 𝑇𝑁 in the temperature range of the resistivity peak.

Here, we demonstrate that the DC bias strain-dependence of AC elastocaloric effect allows decomposition of the latter into symmetric (rotation-symmetry-preserving) and antisymmetric (rotation-symmetry-breaking) strain channels, using a tetragonal \r\n-electron intermetallic DyB2C2—whose antiferroquadrupolar order breaks local fourfold rotational symmetries while globally remaining tetragonal—as a showcase example. We capture the strain evolution of its quadrupolar and magnetic phase transitions using both singularities in the elastocaloric coefficient and its jumps at the transitions, and the latter we show follows a modified Ehrenfest relation. We find that antisymmetric strain couples to the underlying order parameter in a biquadratic (linear-quadratic) manner in the antiferroquadrupolar (canted antiferromagnetic) phase, which are attributed to a preserved (broken) global tetragonal symmetry, respectively. The broken tetragonal symmetry in the magnetic phase is further evidenced by elastocaloric strain-hysteresis and optical birefringence. Additionally, within the staggered quadrupolar order, the observed elastocaloric response reflects a quadratic increase of entropy with antisymmetric strain, analogous to the role magnetic field plays for Ising antiferromagnetic orders by promoting pseudospin flips. Our results demonstrate AC elastocaloric effect as a compact and incisive thermodynamic probe into the coupling between electronic degrees of freedom and strain in free energy, which holds the potential for investigating and understanding the symmetry of a wide variety of ordered phases in broader classes of quantum materials."}],"article_number":"e2302800120","volume":120,"intvolume":" 120","date_updated":"2025-06-10T13:13:53Z","OA_type":"hybrid","extern":"1","type":"journal_article","publisher":"National Academy of Sciences","language":[{"iso":"eng"}],"year":"2023","fulldoi":"https://doi.org/10.1073/pnas.2302800120","pmid":1,"oa_version":"Published Version","OA_place":"publisher","publication_status":"published","article_processing_charge":"No","oa":1,"_id":"19821","title":"Elastocaloric signatures of symmetric and antisymmetric strain-tuning of quadrupolar and magnetic phases in DyB2C2","publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"date_created":"2025-06-10T09:20:12Z"},{"tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"date_published":"2023-04-10T00:00:00Z","has_accepted_license":"1","external_id":{"pmid":["38081228"],"arxiv":["2303.02017"]},"scopus_import":"1","citation":{"ama":"Sun F, Mishra S, McGuinness PH, et al.

Furthermore, we demonstrate experimentally and mathematically that isotropic in-plane diffusivity can be obtained when overlapping the two laser beams instead of separating them in the traditional way, which further enhances the spatial resolution to a micron scale, especially valuable when studying inhomogeneous or multidomain samples. We discuss in detail the experimental conditions under which this technique is valuable and demonstrate its performance on two stoichiometric bilayer ruthenates: Sr3Ru2O7 and Ca3Ru2O7. The spatial resolution allowed us to study the diffusivity in single domains of the latter, and we uncovered a temperature-dependent in-plane diffusivity anisotropy. Finally, we used the enhanced spatial resolution enabled by overlapping the two beams to measure the temperature-dependent diffusivity of Ti-doped Ca3Ru2O7, which exhibits a metal–insulator transition. We observed large variations of transition temperature over the same sample, originating from doping inhomogeneity and pointing to the power of spatially resolved techniques in accessing inherent properties.","lang":"eng"}],"arxiv":1,"article_number":"043003","volume":94,"publication_identifier":{"issn":["0034-6748"],"eissn":["1089-7623"]},"date_created":"2025-06-10T09:23:29Z","_id":"19828","title":"A spatially resolved optical method to measure thermal diffusivity","article_processing_charge":"Yes (in subscription journal)","oa":1,"fulldoi":"https://doi.org/10.1063/5.0098800","pmid":1,"oa_version":"Published Version","OA_place":"publisher","publication_status":"published"},{"oa_version":"None","fulldoi":"https://doi.org/10.1007/978-3-031-32733-9_26","publication_status":"published","article_processing_charge":"No","department":[{"_id":"KrCh"},{"_id":"KrPi"}],"title":"Weighted acket selection for rechargeable links in cryptocurrency networks: Complexity and approximation","_id":"19985","publication_identifier":{"eisbn":["9783031327339"],"eissn":["1611-3349"],"issn":["0302-9743"],"isbn":["9783031327322"]},"date_created":"2025-07-10T13:15:43Z","abstract":[{"text":"We consider a natural problem dealing with weighted packet selection across a rechargeable link, which e.g., finds applications in cryptocurrency networks. The capacity of a link (u, v) is determined by how much nodes u and v allocate for this link. Specifically, the input is a finite ordered sequence of packets that arrive in both directions along a link. Given (u, v) and a packet of weight x going from u to v, node u can either accept or reject the packet. If u accepts the packet, the capacity on link (u, v) decreases by x. Correspondingly, v’s capacity on (u, v) increases by x. If a node rejects the packet, this will entail a cost affinely linear in the weight of the packet. A link is “rechargeable” in the sense that the total capacity of the link has to remain constant, but the allocation of capacity at the ends of the link can depend arbitrarily on the nodes’ decisions. The goal is to minimise the sum of the capacity injected into the link and the cost of rejecting packets. We show that the problem is NP-hard, but can be approximated efficiently with a ratio of (1 + E) . (1 + square3) for some arbitrary E>0.","lang":"eng"}],"volume":13892,"page":"576-594","date_updated":"2025-12-02T14:02:38Z","intvolume":" 13892","OA_type":"closed access","conference":{"name":"SIROCCO: International Colloquium on Structural Information and Communication Complexity","location":"Alcalá de Henares, Spain","start_date":"2023-06-06","end_date":"2023-06-09"},"publisher":"Springer Nature","type":"conference","year":"2023","project":[{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020"}],"language":[{"iso":"eng"}],"day":"25","alternative_title":["LNCS"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1007/978-3-031-32733-9_26","publication":"30th International Colloquium on Structural Information and Communication Complexity","related_material":{"record":[{"id":"14820","status":"public","relation":"later_version"}]},"quality_controlled":"1","month":"05","status":"public","isi":1,"author":[{"last_name":"Schmid","first_name":"Stefan","full_name":"Schmid, Stefan"},{"last_name":"Svoboda","id":"130759D2-D7DD-11E9-87D2-DE0DE6697425","orcid":"0000-0002-1419-3267","full_name":"Svoboda, Jakub","first_name":"Jakub"},{"last_name":"Yeo","first_name":"Michelle X","id":"2D82B818-F248-11E8-B48F-1D18A9856A87","orcid":"0009-0001-3676-4809","full_name":"Yeo, Michelle X"}],"citation":{"mla":"Schmid, Stefan, et al. “Weighted Acket Selection for Rechargeable Links in Cryptocurrency Networks: Complexity and Approximation.” 30th International Colloquium on Structural Information and Communication Complexity, vol. 13892, Springer Nature, 2023, pp. 576–94, doi:10.1007/978-3-031-32733-9_26.","apa":"Schmid, S., Svoboda, J., & Yeo, M.

In this contribution we move forward to the nonlinear setting of monotone operators with p-growth. This first work is dedicated to a quantitative two-scale expansion result. Fluctuations will be addressed in companion articles. By treating the range of exponents 2≤p<∞ in dimensions d≤3, we are able to consider genuinely nonlinear elliptic equations and systems such as −∇⋅A(x)(1+|∇u|p−2)∇u=f (with A random, non-necessarily symmetric) for the first time. When going from p=2 to p>2, the main difficulty is to analyze the associated linearized operator, whose coefficients are degenerate, unbounded, and depend on the random input A via the solution of a nonlinear equation. One of our main achievements is the control of this intricate nonlinear dependence, leading to annealed Meyers' estimates for the linearized operator, which are key to the quantitative two-scale expansion result.","lang":"eng"}],"arxiv":1,"date_created":"2021-10-23T10:50:55Z","publication_identifier":{"issn":["0003-9527"],"eissn":["1432-0673"]},"title":"Quantitative nonlinear homogenization: Control of oscillations","_id":"10174","oa":1,"article_processing_charge":"No","publication_status":"draft","oa_version":"Preprint","fulldoi":"https://doi.org/10.1007/s00205-023-01895-4"},{"oa":1,"article_processing_charge":"Yes (via OA deal)","publication_status":"published","oa_version":"Published Version","fulldoi":"https://doi.org/10.1002/cpa.22028","date_created":"2021-12-05T23:01:41Z","publication_identifier":{"issn":["0010-3640"],"eissn":["1097-0312"]},"title":"Central limit theorem for linear eigenvalue statistics of non-Hermitian random matrices","_id":"10405","department":[{"_id":"LaEr"}],"file":[{"success":1,"date_created":"2023-10-04T09:21:48Z","file_size":803440,"checksum":"8346bc2642afb4ccb7f38979f41df5d9","content_type":"application/pdf","file_id":"14388","creator":"dernst","file_name":"2023_CommPureMathematics_Cipolloni.pdf","access_level":"open_access","date_updated":"2023-10-04T09:21:48Z","relation":"main_file"}],"date_updated":"2025-03-31T16:00:54Z","intvolume":" 76","volume":76,"page":"946-1034","arxiv":1,"abstract":[{"text":"We consider large non-Hermitian random matrices X with complex, independent, identically distributed centred entries and show that the linear statistics of their eigenvalues are asymptotically Gaussian for test functions having 2+ϵ derivatives.

We find the exact dependence of the limiting variance on the fourth cumulant that was not known before. The proof relies on two novel ingredients: (i) a local law for a product of two resolvents of the Hermitisation of X with different spectral parameters and (ii) a coupling of several weakly dependent Dyson Brownian motions.

The system is assumed to have quasi-positive non-linearities and to satisfy an entropy inequality. The difficulties in establishing global renormalised solutions caused by possibly degenerate diffusion are overcome by introducing a new class of weighted truncation functions. By means of the obtained global renormalised solutions, we study the large-time behaviour of complex balanced systems arising from chemical reaction network theory with non-linear diffusion. When the reaction network does not admit boundary equilibria, the complex balanced equilibrium is shown, by using the entropy method, to exponentially attract all renormalised solutions in the same compatibility class. This convergence extends even to a range of non-linear diffusion, where global existence is an open problem, yet we are able to show that solutions to approximate systems converge exponentially to equilibrium uniformly in the regularisation parameter.","lang":"eng"}],"arxiv":1,"file":[{"creator":"dernst","checksum":"f3f0f0886098e31c81116cff8183750b","content_type":"application/pdf","file_id":"13149","access_level":"open_access","file_name":"2023_JourNonlinearScience_Fellner.pdf","date_updated":"2023-06-19T07:33:53Z","relation":"main_file","success":1,"file_size":742315,"date_created":"2023-06-19T07:33:53Z"}],"date_updated":"2023-08-01T14:40:33Z","intvolume":" 33","language":[{"iso":"eng"}],"year":"2023","type":"journal_article","publisher":"Springer Nature","article_type":"original","day":"07","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","doi":"10.1007/s00332-023-09926-w","quality_controlled":"1","publication":"Journal of Nonlinear Science","author":[{"last_name":"Fellner","first_name":"Klemens","full_name":"Fellner, Klemens"},{"last_name":"Fischer","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87","full_name":"Fischer, Julian L","orcid":"0000-0002-0479-558X","first_name":"Julian L"},{"last_name":"Kniely","first_name":"Michael","full_name":"Kniely, Michael","orcid":"0000-0001-5645-4333","id":"2CA2C08C-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Tang","full_name":"Tang, Bao Quoc","first_name":"Bao Quoc"}],"ddc":["510"],"month":"06","status":"public","isi":1,"citation":{"chicago":"Fellner, Klemens, Julian L Fischer, Michael Kniely, and Bao Quoc Tang. “Global Renormalised Solutions and Equilibration of Reaction-Diffusion Systems with Non-Linear Diffusion.” Journal of Nonlinear Science.

Besides being non-renormalisable by the theory of regularity structures by Hairer et al., it has recently been shown to not even admit nontrivial martingale solutions. In the present work, we give a rigorous and fully quantitative justification of the Dean–Kawasaki equation by considering the natural regularisation provided by standard numerical discretisations: We show that structure-preserving discretisations of the Dean–Kawasaki equation may approximate the density fluctuations of N non-interacting diffusing particles to arbitrary order in N−1 (in suitable weak metrics).
