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.' article_processing_charge: No article_type: original author: - first_name: Amelia May Barnett full_name: Douglass, Amelia May Barnett id: de5f6fda-80fb-11ef-996f-a8c4ecd8e289 last_name: Douglass orcid: 0000-0001-5398-6473 - first_name: Jon M. full_name: Resch, Jon M. last_name: Resch - first_name: Joseph C. full_name: Madara, Joseph C. last_name: Madara - first_name: Hakan full_name: Kucukdereli, Hakan last_name: Kucukdereli - first_name: Ofer full_name: Yizhar, Ofer last_name: Yizhar - first_name: Abhinav full_name: Grama, Abhinav last_name: Grama - first_name: Masahito full_name: Yamagata, Masahito last_name: Yamagata - first_name: Zongfang full_name: Yang, Zongfang last_name: Yang - first_name: Bradford B. full_name: Lowell, Bradford B. last_name: Lowell citation: ama: Douglass AM, Resch JM, Madara JC, et al.

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 article_processing_charge: No article_type: original author: - first_name: Linda full_name: Ye, Linda last_name: Ye - first_name: Yue full_name: Sun, Yue last_name: Sun - first_name: Veronika full_name: Sunko, Veronika id: 23cb1cf6-2c7a-11ef-91a4-f72fc19f20b3 last_name: Sunko orcid: 0000-0003-2724-3523 - first_name: Joaquin F. full_name: Rodriguez-Nieva, Joaquin F. last_name: Rodriguez-Nieva - first_name: Matthias S. full_name: Ikeda, Matthias S. last_name: Ikeda - first_name: Thanapat full_name: Worasaran, Thanapat last_name: Worasaran - first_name: Matthew E. full_name: Sorensen, Matthew E. last_name: Sorensen - first_name: Maja D. full_name: Bachmann, Maja D. last_name: Bachmann - first_name: Joseph full_name: Orenstein, Joseph last_name: Orenstein - first_name: Ian R. full_name: Fisher, Ian R. last_name: Fisher citation: ama: Ye L, Sun Y, Sunko V, et al.

Two laser beams are used, one as a source to locally modulate the sample temperature, and the other as a probe of sample reflectivity, which is a function of the modulated temperature. Thermal diffusivity is obtained from the phase delay between source and probe signals. We combine this technique with a microscope setup in an optical cryostat, in which the sample is placed on a three-axis piezo-stage, allowing for spatially resolved measurements. 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.' article_number: '043003' article_processing_charge: Yes (in subscription journal) article_type: original arxiv: 1 author: - first_name: F. full_name: Sun, F. last_name: Sun - first_name: S. full_name: Mishra, S. last_name: Mishra - first_name: P.

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. acknowledgement: We thank Mahsa Bastankhah and Mohammad Ali Maddah-Ali for fruitful discussions about different variants of the problem.

Developing innovative strategies to directly transform biologically relevant molecules, without any prefunctionalization, is key to further expanding the scope and utility of such transformations. Herein, the direct access to quinazolines and pyrimidines from the corresponding unprotected 1H-indoles and 1H-pyrroles is reported, relying on the implementation of lithium bis(trimethylsilyl)amide (LiHMDS) as a novel nitrogen atom source in combination with commercially available hypervalent iodine reagents. Further application of this strategy in late-stage settings demonstrates its potential in lead structure diversification campaigns. article_processing_charge: No article_type: letter_note author: - first_name: Julia full_name: Reisenbauer, Julia id: 51d862e9-36ee-11f0-86d3-8534c85a5496 last_name: Reisenbauer - first_name: Ann-Sophie K. full_name: Paschke, Ann-Sophie K. last_name: Paschke - first_name: Jelena full_name: Krizic, Jelena last_name: Krizic - first_name: Bence B. full_name: Botlik, Bence B. last_name: Botlik - first_name: Patrick full_name: Finkelstein, Patrick last_name: Finkelstein - first_name: Bill full_name: Morandi, Bill last_name: Morandi citation: ama: Reisenbauer J, Paschke A-SK, Krizic J, Botlik BB, Finkelstein P, Morandi B.

More recently, malononitrile-based HCN donor reagents were shown to undergo the C(sp3)–CN bond activation by the nickel catalyst in the absence of Lewis acids. However, there is a lack of detailed mechanistic understanding of the challenging C(sp3)–CN bond cleavage step. In this work, in-depth kinetic and computational studies using alkynes as substrates were used to elucidate the overall reaction mechanism of this transfer hydrocyanation, with a particular focus on the activation of the C(sp3)–CN bond to generate the active H–Ni–CN transfer hydrocyanation catalyst. Comparisons of experimentally and computationally derived 13C kinetic isotope effect data support a direct oxidative addition mechanism of the nickel catalyst into the C(sp3)–CN bond facilitated by the coordination of the second nitrile group to the nickel catalyst. article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Julia full_name: Reisenbauer, Julia id: 51d862e9-36ee-11f0-86d3-8534c85a5496 last_name: Reisenbauer - first_name: Patrick full_name: Finkelstein, Patrick last_name: Finkelstein - first_name: Marc-Olivier full_name: Ebert, Marc-Olivier last_name: Ebert - first_name: Bill full_name: Morandi, Bill last_name: Morandi citation: ama: Reisenbauer J, Finkelstein P, Ebert M-O, Morandi B.

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. acknowledgement: The authors warmly thank Mitia Duerinckx for discussions on annealed estimates, and Mathias Schäffner for pointing out that the conditions of [14] apply to ̄a in the setting of Theorem 2.2 and for discussions on regularity theory for operators with non-standard growth conditions.

Previously this result was known only for a few special cases; either the test functions were required to be analytic [72], or the distribution of the matrix elements needed to be Gaussian [73], or at least match the Gaussian up to the first four moments [82, 56]. 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. These methods are also the key inputs for our analogous results on the linear eigenvalue statistics of real matrices X that are presented in the companion paper [32].

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. acknowledgement: "We thank the referees for their valuable comments and suggestions.

The singular nature of the Dean–Kawasaki equation presents a substantial challenge for both its analysis and its rigorous mathematical justification. 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). In other words, the Dean–Kawasaki equation may be interpreted as a “recipe” for accurate and efficient numerical simulations of the density fluctuations of independent diffusing particles.' acknowledgement: "We thank the anonymous referee for his/her careful reading of the manuscript and valuable suggestions.
