description: A valid prediction for a physical observable from quantum field theory should be independent of the choice of renormalization scheme -- this is the primary requirement of renormalization group invariance (RGI). Satisfying scheme invariance is a challenging problem for perturbative QCD (pQCD), since a truncated perturbation series does not automatically satisfy the requirements of the renormalization group. Two distinct approaches for satisfying the RGI principle have been suggested in the literature. One is the "Principle of Maximum Conformality" (PMC) in which the terms associated with the $β$-function are absorbed into the scale of the running coupling at each perturbative order; its predictions are scheme and scale independent at every finite order. The other approach is the "Principle of Minimum Sensitivity" (PMS), which is based on local RGI; the PMS approach determines the optimal renormalization scale by requiring the slope of the approximant of an observable to vanish. In this paper, we present a detailed comparison of the PMC and PMS procedures by analyzing two physical observables $R_{e+e-}$ and $Γ(H\to b\bar{b})$ up to four-loop order in pQCD. At the four-loop level, the PMC and PMS predictions for both observables agree within small errors with those of conventional scale setting assuming a physically-motivated scale, and each prediction shows small scale dependences. However, the convergence of the pQCD series at high orders, behaves quite differently: The PMC displays the best pQCD convergence since it eliminates divergent renormalon terms; in contrast, the convergence of the PMS prediction is questionable, often even worse than the conventional prediction based on an arbitrary guess for the renormalization scale. ......

The contribution of the reticular Pentose Phosphate Pathway in glucose metabolism, cell proliferation and in the regulation of the redox state

description: The use of Positron Emission Tomography (PET)/ Computed tomography (CT) with 18F-2-deoxy-glucose (FDG) represents a clinical standard for the diagnosis and monitoring of cancer evolution and in the evaluation of many neurodegenerative syndromes. This method relies on the concept that FDG competes with glucose for trans-membrane transport (GLUTs) and hexokinase (HK)-catalyzed phosphorylation (1). However, FDG-6-phosphate (FDG6P) is a false substrate for downstream enzymes channeling glucose-6P (G6P) to glycolysis, pentose phosphate pathway (PPP) or glycogen synthesis (2-3) and thus accumulates within the cytosol as a function of glucose consumption. Despite the universal acceptance of this kinetic model, the link between glucose consumption and FDG uptake might be relatively looser than conventionally assumed. Indeed, glucose consumption is invariably high also in those cancers (prostate, urothelial and neuroendocrine cancers or glioblastoma) characterized by a very low FDG uptake (4-6). Finally, the theoretical nondegradability of 2DG6P/FDG6P has been recently challenged by two main observations: on the one hand, stoichiometry indicates that a significant fraction of intracellular 2DG is not processed by HKs (7); on the other hand, magnetic resonance spectroscopy documents significant degradation of FDG6 (8-10). To date, the relationship between FDG uptake and glucose consumption is almost universally accepted. Nevertheless, several observations indicate that the link between glucose consumption and FDG accumulation may be relatively looser than conventionally assumed. In agreement with this concept, recent studies recently documented cancer uptake of FDG is closely and selectively dependent on a specific metabolism triggered within the endoplasmic reticulum (ER) by the enzyme hexose-6- phosphate dehydrogenase (H6PD) whose silencing profoundly diminished FDG uptake despite an increase in glycolytic flux (11). This autosomic counterpart of the cytosolic glucose-6-phosphate-dehydrogenase (G6PD) can dehydrogenate many hexoses, including 2-deoxy-glucose (2DG), to trigger pentose-phosphate pathway (PPP) and thus to fuel the high NADPH within the ER lumen (12-14). My project aimed to study the role of H6PD in FDG uptake or, more in general, to evaluate the contribution of the ER-PPP in global cell glucose metabolism, proliferation, and regulation of the redox state. Obtained results indicate that FDG uptake is indeed strictly dependent upon the activation of ER metabolic machinery and only loosely related to glycolytic flux. More importantly, they also suggest an unexpected relevance of ER glucose metabolism in feeding the high NADPH equivalents required by cells with high proliferating activity or exposed to an intense redox stress.

Year: 2023

description: The present study examines how the COVID-19 pandemic affects college students' mental health and well-being. Furthermore, the study investigates the association between psychological resilience, daily functioning, and trajectories of mental distress during the COVID-19 pandemic. Our sample included 208 college students from a private University in Cyprus. Students completed the COVID-19 Functioning Scale, the Perceived Stress Scale, the Depression Anxiety Stress Scale, and the Connor Davidson Resilience Scale. Statistical analyses highlighted that COVID-19 perceived challenges negatively impacted students' mental health and well-being. In addition, results revealed that students with a higher level of resilience and a healthier daily routine and functioning indicate lower levels of perceived stress and mental difficulties. Study findings highlighted that high resilience and functioning could be protective factors for students' well-being during the pandemic. Thus, activities that foster resilience should be included in broader strategies to support students' mental health and well-being.

description: Nonstandard on-shell decays of $W^\pm$ and $Z$ bosons are possible within the framework of extended supersymmetric models, i.e., with singlet states and/or new couplings compared to the minimal supersymmetric standard model. These modes are typically encountered in regions of the parameter space with light singlet-like scalars, pseudoscalars, and neutralinos. In this letter we emphasize how these states can lead to novel signals at colliders from $Z$- or $W^\pm$-boson decays with prompt or displaced multileptons/tau jets/jets/photons in the final states. These new modes would give distinct evidence of new physics even when direct searches remain unsuccessful. We discuss the possibilities of probing these new signals using the existing LHC run-I data set. We also address the same in the context of the LHC run-II, as well as for the future colliders. We exemplify our observations with the "$μ$ from $ν$" supersymmetric standard model, where three generations of right-handed neutrino superfields are used to solve shortcomings of the minimal supersymmetric standard model. We also extend our discussion for other variants of supersymmetric models that can accommodate similar signatures.

Growth, coalescence and equilibration of metallic nanoparticles and nanoalloys studied by computational methods
Creators: name: NELLI, DIANA
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: Among nanoscale systems, metallic nanoparticles (NPs) certainly play a primary role, due to their highly tunable properties and to the wide variety of their applications. The properties of NPs are known to strongly depend on their size and geometric shape. In the case of bimetallic nanoparticles, also known as nanoalloys, further parameters can be exploited, i.e. the NP composition and the spatial arrangement of the two atomic species within the NP volume, here referred to as chemical ordering. Within this framework, the fine control of the NP configuration (here intended as the interplay between size, shape, composition and chemical ordering) is essential in sight of the possible technological applications. To this aim, a deep understanding of the NP formation process is highly desirable: one has to clearly know what are the different stages of such process, and what are the physical forces and the chemical effects involved. Moreover, a clear knowledge of the thermodynamic stability of the produced phases under the operating conditions is desirable as well. Computer simulations can be of great help in this sense, as they can provide clear information on both the equilibrium properties and the kinetic behaviour of the NPs. Specifically, the most thermodynamically favourable configurations of a given system can be determined, and the evolution pathways can be simulated and analysed at the atomic level, therefore allowing to rationalize the experimental findings. This Ph.D. thesis is devoted to the computational study of mono- and bi-metallic NPs, with particular attention to some of the nonequilibrium phenomena undergone by them. Different examples are presented and discussed; specifically, different metallic systems are treated, all of which are of great interest due to their practical applications, and different phenomena are analysed.

description: This paper analyzes the effect of Foreign Direct Investment in Land acquisition and cultural difference between investors and host government on the likelihood of the outbreak of Civil Disputes in Developing Countries. The study highlights two significant mechanisms through which FDI can potentially ignite civil unrest in developing nations. Firstly, foreign land acquisitions can exacerbate land disputes and protests due to intensified competition and conflicting perceptions of land ownership. Secondly, cultural disparities between MNCs and local communities can breed misunderstandings and mistrust, prompting protests against perceived cultural infringements and calls for reduced foreign business operations. Through the analysis of a sample of 15 developing countries from Latin America and Africa from 2008 to 2017, the statistical results suggested that FDI in land has a controversial effect on the occurrence of domestic farmer-related disputes in developing economies, and the occurrence of localities-MNC disputes tends to decrease in countries where their beliefs in work ethics align more closely with the investing economy.

description: Nuclear short-range correlations (SRC) typically manifest themselves in the tail parts of the single-nucleon momentum distributions. We propose an approximate practical method for computing those SRC contributions to the high-momentum parts. The framework adopted in this work is applicable throughout the nuclear mass table and corrects mean-field models for central, spin-isospin and tensor correlations by shifting the complexity induced by the SRC from the wave functions to the operators. It is argued that the expansion of these modified operators can be truncated to a low order. The proposed model can generate the SRC-related high-momentum tail of the single-nucleon momentum distribution. These are dominated by correlation operators acting on mean-field pairs with vanishing relative radial and angular-momentum quantum numbers. The proposed method explains the dominant role of proton-neutron pairs in generating the SRC and accounts for the magnitude and mass dependence of SRC as probed in inclusive electron scattering. It also provides predictions for the ratio of the amount of correlated proton-proton to proton-neutron pairs which are in line with the observations. In asymmetric nuclei, the correlations make the average kinetic energy for the minority nucleons larger than for the majority nucleons.

The role of inflammation on disease progression in alpha-sarcoglycan-related limb girdle muscular dystrophy (LGMDR3): new insights from human histological analysis and in vivo studies on Sgca-null mice.
Creators: name: PANICUCCI, CHIARA
Publisher: name: Universit� degli studi di Genova

description: Limb Girdle Muscular Dystrophy R3 (LGMDR3), previously known as LGMD2D, is a rare autosomal recessive primary myopathy, clinically characterized by progressive involvement of the pelvic and shoulder girdles, and genetically by mutations in the ?sarcoglycan gene (SGCA) coding for ?-sarcoglycan (SG). The clinical course of LGMDR3 presents a great variability, ranging from severe form with onset in the first decade of life and rapid progression, to milder form with later onset. Currently, physical therapy and prevention of secondary cardiac, pulmonary or orthopedic complications are the only possible care interventions and no disease-specific therapies are yet available. As other muscular dystrophies, LGMDR3 muscle histology is characterized by myofibernecrosis and regeneration, reactive fibrosis, and inflammatory infiltrates. However, to date, no data exploring the role of immune response on disease progression have been published. The primary objective of this PhD thesis was therefore to deepen the contribution of inflammatory processes to the severity of ?-sarcoglycanopathy. AIM1. -to correlate the inflammatory infiltrates extension with the age at onset, the clinical severity, and the muscle involvement at MRI, in a cohort of patients followed at Istituto Giannina Gaslini, Genova In a cohort of 8 LGMDR3 patients, we characterized the clinical course, the MRI muscle pattern, and the histological parameters, focusing on inflammatory features. AIM2.-to immunophenotype the composition of muscular immune infiltrates in different sarcoglycanopathies and verify whether differences would be detectable between distinct subtypes of sarcoglycan-related LGMDs In a multicenter study involving Italian tertiary centers for neuromuscular disorders, we analysed muscle expression of inflammatory markers in two forms of sacoglycanopathies LGMDR3 and LGMDR5, the latter due to deficiency of ?-sarcoglycan. AIM3.-to study the in vivo effect of anti-purinergic molecules on disease progression in the Sgca null mouse In two pre-clinical studies, we explored the role of the P2X7 receptor, a ionotrophic receptor involved in the inflammasome pathway which mediates the release of pro-inflammatory cytokines, in a mouse model lacking the ?-sarcoglycan gene (Sgca-null).

description: Abstract: Liver turquoise is one of the silent and dangerous diseases. If it can be detected in the early stages, the lives of many affected people can be saved. Providing smart methods to identify and diagnose this disease can save patients' lives in addition to reducing medical costs and overheads. In this research, an innovative method using a three-layer radial basis neural network is proposed as a multi-class method for diagnosing liver fibrosis. To increase the accuracy and efficiency of the pre-processed data, the data are balanced using the SMOT method. Also, feature selection is done with the bee algorithm. In this way, the desired features are first reduced using the bee algorithm. For this purpose, a mapping of features is done using the bee algorithm. Then the data with reduced features are applied to the proposed RBF network. The simulation results show that the proposed method is 5% more accurate than similar methods
Hypersurface foliation approach to renormalization of ADM formulation of gravity

Year: 2014
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We carry out ADM splitting in the Lagrangian formulation and establish a procedure in which (almost) all of the unphysical components of the metric are removed by using the 4D diffeomorphism and the measure-zero 3D symmetry. The procedure introduces a constraint that corresponds to the Hamiltonian constraint of the Hamiltonian formulation, and its solution implies that the 4D dynamics admits an effective description through 3D hypersurface physics. As far as we can see, our procedure implies potential renormalizability of {the ADM formulation of} 4D Einstein gravity for which a complete gauge-fixing in the ADM formulation and hypersurface foliation of geometry are the key elements. If true, this implies that the alleged unrenormalizability of 4D Einstein gravity may be due to the presence of the unphysical fields. The procedure can straightforwardly be applied to quantization around a flat background; the Schwarzschild case seems more subtle. We discuss a potential limitation of the procedure when applying it to explicit time-dependent backgrounds.

description: The presence of scaling variables in experimental observables provide very valuable indications of the dynamics underlying a given physical process. In the last years, the search for geometric scaling, that is the presence of a scaling variable which encodes all geometrical information of the collision as well as other external quantities as the total energy, has been very active. This is motivated, in part, for being one of the genuine predictions of the Color Glass Condensate formalism for saturation of partonic densities. Here we extend these previous findings to the case of experimental data on elliptic flow. We find an excellent scaling for all centralities and energies, from RHIC to LHC, with a simple generalization of the scaling previously found for other observables and systems. Interestingly the case of the photons, difficult to reconcile in most formalisms, nicely fit the scaling curve. We discuss the possible interpretations of this finding in terms of initial or final state effects.

description: Several results on existence and convergence of the Yang-Mills flow in dimension four are given. We show that a singularity modeled on an instanton cannot form within finite time. Given low initial self-dual energy, we then study convergence of the flow at infinite time. If an Uhlenbeck limit is anti-self-dual and has vanishing self-dual second cohomology, then no bubbling occurs and the flow converges exponentially. We also recover Taubes's existence theorem, and prove asymptotic stability in the appropriate sense.

description: Physical activity is an important tool for integration and inclusion that leads to respect for diversity because the need to move is also fundamental in the person with disabilities as it expresses their physical, emotional, mental, and social potential that emerges in the dimension in which the subject is in tune with himself, the family, the community and the world in general. Motor activities represent a privileged meeting point of diversity, which is thus included without distinction using the abilities of each one. The heterogeneity of students with special educational needs requires the implementation of a variety of responses that, by combining good didactic/educational planning with innovative pedagogical devices, are able to carry out individualized and personalized interventions by enhancing the resources of the school community. The present work, focusing on corporeality as a cognitive device, opens a reflection on the way in which to operationalize the educational process by initiating and implementing new personalized teaching protocols

Die Gesamterfahrung mit dem „Prototype Installation Test“ hat gezeigt, dass Langzeittests von neu entwickelten HGÜ-Prototypen wichtige Erkenntnisse für die spätere Netzinstallation liefern, die mit Typprüfungen und üblichen FAT- und SAT-Tests allein nicht gefunden worden wären. Die während der Inbetriebnahme gesammelten Erfahrungen haben gezeigt, wie durch ein erweitertes Inbetriebnahmeverfahren alle typischen HGÜ-Fehler erkannt werden können. Ereignisse während der Inbetriebnahme zeigen Potenziale für zukünftige Optimierungen am DC-GILPrototyp, z. B. weitere Partikelfallenmaßnahmen.

description: Language barriers, sociocultural barriers and academic adjustment are some of the main factors affecting international students’ experience in foreign universities. Focusing on the Italian context, the present study aims to evaluate to which extent the language anxiety, the perceived practical-emotional support of local or foreign peers, the perceived effectiveness institutional communication, and communication channel used affect international students’ feeling of belonging and academic performance. Data were collected with 185 international students from the largest university in Rome, using an anonymous online questionnaire. Results show that language anxiety levels affect with academic success; also, the support received by local students, the emotional support received by international students, and the effectiveness of information provided by the university affect the feeling of belonging to the university. Practical support received by other international negatively affect feeling of belonging. Age, gender also have significant effects in this context. These findings encourage institution to actively pursue the integration of international students with the local students and community, enhancing individual skills and opportunities for socialization with host and international students.

description: We investigate the ground state properties of Bose-Bose mixtures with Rashba-type spin-orbit (SO) coupling in a square lattice. The system displays rich physics from the deep Mott-insulator (MI) all the way to the superfluid (SF) regime. In the deep MI regime, novel spin-ordered phases arise due to the effective Dzyaloshinskii-Moriya type super-exchange interactions. By employing the non-perturbative Bosonic Dynamical Mean-Field-Theory (BDMFT), we numerically study and establish the stability of these magnetic phases against increasing hopping amplitude. We show that as hopping is increased across the MI to SF transition, exotic superfluid phases with magnetic textures emerge. In particular, we identify a new spin-spiral magnetic texture with spatial period 3 in the superfluid close to the MI-SF transition.

description: We consider bipartite SU($N$) spin Hamiltonians with a fundamental representation on one sublattice and a conjugate to fundamental on the other sublattice. By mapping these antiferromagnets to certain classical loop models in one higher dimension, we provide a practical strategy to write down a large family of SU($N$) symmetric spin Hamiltonians that satisfy Marshall's sign condition. This family includes all previously known sign-free SU($N$) spin models in this representation and in addition provides a large set of new models that are Marshall positive and can hence be studied efficiently with quantum Monte Carlo methods. As an application of our idea to the square lattice, we show that in addition to Sandvik's $Q$-term, there is an independent non-trivial four-spin $R$-term that is sign-free. Using numerical simulations, we show how the $R$-term provides a new route to the study of quantum criticality of Néel order.

description: We consider numerical integrators of ODEs on homogeneous spaces (spheres, affine spaces, hyperbolic spaces). Homogeneous spaces are equipped with a built-in symmetry. A numerical integrator respects this symmetry if it is equivariant. One obtains homogeneous space integrators by combining a Lie group integrator with an isotropy choice. We show that equivariant isotropy choices combined with equivariant Lie group integrators produce equivariant homogeneous space integrators. Moreover, we show that the RKMK, Crouch--Grossman or commutator-free methods are equivariant. To show this, we give a novel description of Lie group integrators in terms of stage trees and motion maps, which unifies the known Lie group integrators. We then proceed to study the equivariant isotropy maps of order zero, which we call connections, and show that they can be identified with reductive structures and invariant principal connections. We give concrete formulas for connections in standard homogeneous spaces of interest, such as Stiefel, Grassmannian, isospectral, and polar decomposition manifolds. Finally, we show that the space of matrices of fixed rank possesses no connection.

description: Motivated by the separability problem in quantum systems $2\otimes4$, $3\otimes3$ and $2\otimes2\otimes2$, we study the maximal (proper) faces of the convex body, $S_1$, of normalized separable states in an arbitrary quantum system with finite-dimensional Hilbert space $H=H_1\otimes H_2\otimes\cdots\otimes H_n$. To any subspace $V$ of $H$ we associate a face $F_V$ of $S_1$ consisting of all states $ρ\in S_1$ whose range is contained in $V$. We prove that $F_V$ is a maximal face if and only if $V$ is a hyperplane. If $V$ is the hyperplane orthogonal to a product vector, we prove that $\dim F_V=d^2-1-\prod(2d_i-1)$, where $d_i$ is the dimension of $H_i$ and $d=\prod d_i$. We classify the maximal faces of $S_1$ in the cases $2\otimes2$ and $2\otimes3$. In particular we show that the minimum and the maximum dimension of maximal faces is 6 and 8 for $2\otimes2$, and 20 and 24 for $2\otimes3$. The boundary of $S_1$ is the union of all maximal faces. When $d>6$ we prove that there exist full states $ρ$ on the boundary, i.e., such that all partial transposes of $ρ$ (including $ρ$ itself) have rank $d$. K.-C. Ha and S.-K. Kye have recently constructed explicit such states in $2\times4$ and $3\otimes3$. In the latter case, they have also constructed a remarkable family of faces, depending on a real parameter $b>0$, $b\ne1$. Each face in the family is a 9-dimensional simplex and any interior point of the face is a full state. We construct suitable optimal entanglement witnesses (OEW) for these faces and analyze the three limiting cases $b=0,1,\infty$.

description: One of the most important challenges facing the evolution of smart cities over the last decade has been the optimization of energy use. Also, artificial intelligence and its algorithms, such as reinforcement learning, have appeared as a catalyst in the process of designing and optimizing smart services in the urban space, and in this issue, the generation and use of energy are critical factors. Using a technique based on reinforcement learning, the authors of this research successfully decreased and optimised smart city energy use. The suggested reinforcement learning method uses a collection of agents to cooperate together to achieve a shared objective using an optimum energy distribution policy (value action function). Agents’ ability to cooperate to optimise energy use and save expenses is only one example of the many advantages that will accrue from their concerted efforts. To determine the worth of each option, the suggested technique looks at energy consumption data and the degree to which the option has been implemented in the past. This architecture ensures the device achieves an optimal balance between its energy footprint and the dependability of its communications. The simulation findings reveal that the yearly energy consumption in the smart city may be reduced by more than 35%-40% via the optimization of energy consumption using the proposed reinforcement learning approach.

description: The above thesis deals with the problematic question of psychological assistence in the crime, analyzing the difficulties in demonstrate causal relationship in the field of interpersonal transactions. The repression of psychological assistence postulates a delicate balance between the costitutional principles in the criminal law (such as that of the personality of criminal liability and of freedom of expression of thought) and the pressing demands of justice.

description: El auto-diagnóstico sociolingüístico hace parte del plan de acciones del Programa de Protección a la Diversidad Etnolingüística del Ministerio de Cultura, el cual tiene como objetivo impulsar el reconocimiento, la protección, el uso y, en general, el fortalecimiento de las lenguas nativas de Colombia. El auto-diagnóstico es un estudio, realizado por los hablantes de las lenguas nativas con el acompañamiento del Ministerio de Cultura, que busca conocer el estado de vitalidad de las lenguas nativas mediante la aplicación de una encuesta a los jefes de hogar en cada uno de los pueblos. Se denomina auto-diagnóstico porque es realizado por los miembros de los pueblos étnicos, quienes se convierten en los responsables, líderes de este proceso y primeros interesados en este estudio, y porque refleja la percepción de los hablantes sobre el uso de la lengua.
La tutela penale delle indagini nell'Amministrazione della giustizia.
Creators: name: ZANNONI, ILARIA
Publisher: name: Universit� degli studi di Genova
Year: 2021

description: The Rocco code for the first time gave protection to the "good of justice" by dedicating to it a special title entitled "crimes against the Administration of justice". In particular, within this group of crimes, the cases that incriminate false statements not only to the judicial authority, but also to subjects who, although not part of it, operate in close collaboration with the organs of the jurisdiction or, more generally, of the judicial power, assume a certain importance. The purpose of this work is to analyze the lights and the shadows of this discipline by looking at the legislative interventions of the last thirty years, driven by our Constitutional Charter which has given greater value to the "good justice" as well as the pronouncements of the supreme courts.

description: Using a community sample of 323 individuals (74% women; Mean Age = 26.9 years), who completed an online survey from April 2021 to April 2022, the present study explored the relations among attitudes towards a variety of social and political issues that sparked social media debate. The study used the Attitudes towards Social and Political Issues (ASPI) survey, which covers attitudes towards COVID-19, vaccines, the European Union, migrants, LGBTQ+ rights, gender equality, religion, and conspiracy beliefs. Using an Exploratory Graph Analysis, the study discovered three attitude communities. The first community, labeled equal rights inclusion, encompassed positive attitudes towards LGBTQ+ rights and gender equality. The second community, labeled national populism, included hostility towards immigrants and anti-EU sentiments. The third community, labeled religiosity, emerged as an autonomous cluster related to national populism positively and equal rights and inclusion negatively. The ASPI scores were sensitive to individual differences in political and religious orientation. The national populism score was the most likely proxy for political orientation, while religiosity marked the difference between those who said they were Christians, or followed other religious or spiritual doctrines, and atheists or agnostics. Overall, the study provides insight into the complex social and political landscape in Italy during the Draghi government.

description: Axions are well motivated particles that could make up most or all of the dark matter if they have masses below 100 $μ$eV. Microwave cavity techniques comprised of closed resonant structures immersed in solenoid magnets are sensitive to dark matter axions with masses of a few $μ$eV, but face difficulties scaling to higher masses. We present the a novel detector architecture consisting of an open, Fabry-Pérot resonator and a series of current-carrying wire planes, and demonstrate this technique with a search for dark matter axion-like particles called Orpheus. This search excludes dark matter axion-like particles with masses between 68.2 and 76.5 $μ$eV and axion-photon couplings greater than $4\times10^{-7} \mathrm{GeV}^{-1}$. We project that the fundamental sensitivity of this technique could be extended to be sensitive to couplings below $1\times10^{-15} \mathrm{GeV}^{-1}$, consistent with the DFSZ model of QCD axions.

description: We generalize the classical Hardy and Faber-Krahn inequalities to arbitrary functions on a convex body $Ω\subset \mathbb{R}^n$, not necessarily vanishing on the boundary $\partial Ω$. This reduces the study of the Neumann Poincaré constant on $Ω$ to that of the cone and Lebesgue measures on $\partial Ω$; these may be bounded via the curvature of $\partial Ω$. A second reduction is obtained to the class of harmonic functions on $Ω$. We also study the relation between the Poincaré constant of a log-concave measure $μ$ and its associated K. Ball body $K_μ$. In particular, we obtain a simple proof of a conjecture of Kannan--Lovász--Simonovits for unit-balls of $\ell^n_p$, originally due to Sodin and Latała--Wojtaszczyk.
