description: Axion electrodynamics, first proposed in the context of particle physics, manifests itself in condensed matter physics in the topological field theory description of 3d topological insulators and gives rise to magnetoelectric effect, where applying magnetic (electric) field $\mathbf{B}(\mathbf{E})$ induces polarization (magnetization) $\mathbf{p}(\mathbf{m})$. We use linear response theory to study the associated topological current using the Fu-Kane-Mele model of 3d topological insulators in the presence of time-dependent uniform weak magnetic field. By computing the dynamical current susceptibility $χ^{\mathbf{j}_p\mathbf{j}_p}_{ij}(ω)$, we discover from its static limit an `order parameter' of the topological phase transition between weak topological (or ordinary) insulator and strong topological insulator, found to be continuous. The $χ^{\mathbf{j}_p\mathbf{j}_p}_{ij}(ω)$ shows a sign-changing singularity at a critical frequency with suppressed strength in the topological insulating state. Our results can be verified in current noise experiment on 3d TI candidate materials for the detection of such topological phase transition.

description: We investigate the energy dispersion of the edge states in zigzag silicene, germanene and stanene nanoribbons with and without hydrogen termination based on a multi-orbital tight-binding model. Since the low buckled structures are crucial for these materials, both the $π$ and $σ$ orbitals have a strong influence on the edge states, different from the case for graphene nanoribbons. The obtained dispersion of helical edge states is nonlinear, similar to that obtained by first-principles calculations. On the other hand, the dispersion derived from the single-orbital tight-binding model is always linear. Therefore, we find that the non-linearity comes from the multi-orbital effects, and accurate results cannot be obtained by the single-orbital model but can be obtained by the multi-orbital tight-binding model. We show that the multi-orbital model is essential for correctly understanding the dispersion of the edge states in tetragen nanoribbons with a low buckled geometry.

description: By generalising concepts from classical stochastic dynamics, we establish the basis for a theory of metastability in Markovian open quantum systems. Partial relaxation into long-lived metastable states - distinct from the asymptotic stationary state - is a manifestation of a separation of timescales due to a splitting in the spectrum of the generator of the dynamics. We show here how to exploit this spectral structure to obtain a low dimensional approximation to the dynamics in terms of motion in a manifold of metastable states constructed from the low-lying eigenmatrices of the generator. We argue that the metastable manifold is in general composed of disjoint states, noiseless subsystems and decoherence-free subspaces.

Study on the mapping of dark matter clustering from real space to redshift space

description: The mapping of dark matter clustering from real space to redshift space introduces the anisotropic property to the measured density power spectrum in redshift space, known as the redshift space distortion effect. The mapping formula is intrinsically non-linear, which is complicated by the higher order polynomials due to indefinite cross correlations between the density and velocity fields, and the Finger-of-God effect due to the randomness of the peculiar velocity field. Whilst the full higher order polynomials remain unknown, the other systematics can be controlled consistently within the same order truncation in the expansion of the mapping formula, as shown in this paper. The systematic due to the unknown non-linear density and velocity fields is removed by separately measuring all terms in the expansion directly using simulations. The uncertainty caused by the velocity randomness is controlled by splitting the FoG term into two pieces, 1) the "one-point" FoG term being independent of the separation vector between two different points, and 2) the "correlated" FoG term appearing as an indefinite polynomials which is expanded in the same order as all other perturbative polynomials. Using 100 realizations of simulations, we find that the Gaussian FoG function with only one scale-independent free parameter works quite well, and that our new mapping formulation accurately reproduces the observed 2-dimensional density power spectrum in redshift space at the smallest scales by far, up to $k\sim 0.2h$Mpc, considering the resolution of future experiments.

RBEE extract showed acetyl-cholinesterase inhibition higher than the reference compound Galantamine at a concentrationof 200 µg/mL. A moderate antibacterial activity of the extract was also obtained against Staphylococcus aureus ATCC43300, Citrobacter freundii ATCC8090, and Proteus vulgaris ATCC29905 at a concentration 100 µg. Additionally, a good reduction in plasma coagulation time at 200 μL was also observed for RBEE.

description: We prove that a system of non-interacting electrons proximity coupled to a conventional s-wave superconductor cannot realize a time reversal invariant topological phase. This is done by showing that for such a system, in either one or two dimensions, the topological invariant of the corresponding symmetry class (DIII) is always trivial. Our results suggest that the pursuit of Majorana bound states in time-reversal invariant systems should be aimed at interacting systems or at proximity to unconventional superconductors.

EC behaviour in PAH

description: Endothelial cells (ECs) are highly heterogenous across different organs and within the vascular bed, in both health and disease. However, EC heterogeneity has not been extensively dissected in the context of pulmonary arterial hypertension (PAH). It is a rare and progressive disease characterised by remodelling of the distal pulmonary vasculature. Using an EC lineage-tracing mouse model and single-cell RNA-sequencing (scRNA-seq), I first investigated how enriched mouse ECs respond to Sugen 5416/Hypoxia-induced (SuHx) PAH. Globally, ECs adopt an immunophenotype in PAH, with upregulation of genes relating to the major histocompatibility class II (MHC-II) complex. The strongest upregulation is observed in Artery and one of the two capillary ECs (Capillary A/gCap). The other capillary EC cluster (Capillary B/aerocyte) had a distinct response to PAH, with upregulation of genes regulating apoptosis, migration, and angiogenesis. Comparison with whole-lung scRNA-seq in rat and human PAH identified several candidate genes conserved across all species. Following this, I further examined heterogeneity within Artery and Capillary A ECs, the pulmonary vasculature predominantly affected in PAH. Artery ECs can be subdivided into Proximal and Distal Artery ECs, with both groups having distinct biomarkers. In PAH, a loss of Proximal Artery EC identity and a gain in Distal Artery EC identity is observed. As for Capillary A ECs, three subpopulations were identified. In Control, two of these subclusters (CapillaryA_0, CapillaryA_1) were marked by high expression of Distal Artery markers, and low expression of Proximal Artery markers, whilst the reverse was true for the third CapillaryA_2 subcluster. There was also significantly more CapillaryA_2 ECs in PAH. Differential gene expression analysis found some genes uniquely upregulated in each CapillaryA subcluster: senescence-associated genes in CapillaryA_0 (Cd9, H3f3b, Neat1), signalling genes in CapillaryA_1 (Rab5a, Slc6a6, Tmem252), and both inflammatory (H2-Q4, Irgm1, Tgtp2) and angiogenesis regulatory genes (Cldn5, Cxcl12, Esam, Rhoj) in CapillaryA_2. Overall, this work has revealed in high-resolution, how ECs in different vascular beds distinctly respond to PAH.

description: We study the a priori error analysis of finite element methods for Biot's consolidation model. We consider a formulation which has the stress tensor, the fluid flux, the solid displacement, and the pore pressure as unknowns. Two mixed finite elements, one for linear elasticity and the other for mixed Poisson problems are coupled for spatial discretization, and we show that any pair of stable mixed finite elements is available. The novelty of our analysis is that the error estimates of all the unknowns are robust for material parameters. Specifically, the analysis does not need a uniformly positive storage coefficient, and the error estimates are robust for nearly incompressible materials. Numerical experiments illustrating our theoretical analysis are included.

description: The neutron multiplier is an essential component of the blanket of future thermonuclear reactors, which should provide the tritium breeder with a sufficient amount of neutrons of a certain energy. Among all chemical elements, only beryllium and lead have an advantageous ratio of high neutron multiplication reaction at low neutron absorption rates. However, pure metals – beryllium and lead – for various reasons cannot be used in the harsh operating conditions of a fusion reactor blanket. Intermetallic compounds of beryllium – beryllides have a number of advantages over pure beryllium and are currently considered to be the reference neutron multiplication material for the Helium Cooled Pebble Bed (HCPB) breeding blanket concept of EU DEMO fusion reactor. Recently, a batch of full-size beryllide blocks has been manufactured on an industrial scale in cooperation with the Ulba Metallurgical Plant. The present work is devoted to the characterization and analysis of these beryllide blocks so that the material could be used for the manufacture of a blanket. Titanium beryllide (TiBe12) blocks are hexagonal prisms with an internal hole, while chromium beryllide (CrBe12) blocks are solid prisms of complex shape. The resulting blocks have a single-phase structure of the corresponding beryllide with a small impurity in the form of beryllium oxide. One of the titanium beryllide blocks also has about 7% residual beryllium phase. Grains of titanium beryllide have an average size of about 7–8 μm, while grains of chromium beryllide are much larger and reach 40–50 μm. Mechanical compression and bending tests of beryllides showed their very high strength, which is maintained up to 1000°C. In terms of specific compressive strength, the single-phase TiBe12 surpasses all materials, except diamond, in the 700–1000°C temperature range. Chromium beryllide and titanium beryllide with 7% of the beryllium phase have lower strength, but higher ductility. Corrosion tests were carried out in air and in He + 2% water vapor at 800–1200°C. Beryllides have high corrosion resistance similar to Ni-base superalloys and high temperature ceramics. Long-term thermal cycling tests with rapid heating and cooling, simulating operation in a fusion reactor, showed high resistance of beryllides to thermal shocks. The results obtainedare also discussed from the point of view of the application of beryllides in other areas.

description: Digital Twin -- a virtual replica of a physical system enabling real-time monitoring, model updating, prediction, and decision-making -- combined with recent advances in machine learning, offers new opportunities for proactive control strategies in autonomous manufacturing. However, achieving real-time decision-making with Digital Twins requires efficient optimization driven by accurate predictions of highly nonlinear manufacturing systems. This paper presents a simultaneous multi-step Model Predictive Control (MPC) framework for real-time decision-making, using a multivariate deep neural network, named Time-Series Dense Encoder (TiDE), as the surrogate model. Unlike conventional MPC models which only provide one-step ahead prediction, TiDE is capable of predicting future states within the prediction horizon in one shot (multi-step), significantly accelerating the MPC. Using Directed Energy Deposition (DED) additive manufacturing as a case study, we demonstrate the effectiveness of the proposed MPC in achieving melt pool temperature tracking to ensure part quality, while reducing porosity defects by regulating laser power to maintain melt pool depth constraints. In this work, we first show that TiDE is capable of accurately predicting melt pool temperature and depth. Second, we demonstrate that the proposed MPC achieves precise temperature tracking while satisfying melt pool depth constraints within a targeted dilution range (10\%-30\%), reducing potential porosity defects. Compared to PID controller, the MPC results in smoother and less fluctuating laser power profiles with competitive or superior melt pool temperature control performance. This demonstrates the MPC's proactive control capabilities, leveraging time-series prediction and real-time optimization, positioning it as a powerful tool for future Digital Twin applications and real-time process optimization in manufacturing.
POD-Galerkin reduced-order modeling with adaptive finite element snapshots

description: We consider model order reduction by proper orthogonal decomposition (POD) for parametrized partial differential equations, where the underlying snapshots are computed with adaptive finite elements. We address computational and theoretical issues arising from the fact that the snapshots are members of different finite element spaces. We propose a method to create a POD-Galerkin model without interpolating the snapshots onto their common finite element mesh. The error of the reduced-order solution is not necessarily Galerkin orthogonal to the reduced space created from space-adapted snapshot. We analyze how this influences the error assessment for POD-Galerkin models of linear elliptic boundary value problems. As a numerical example we consider a two-dimensional convection-diffusion equation with a parametrized convective direction. To illustrate the applicability of our techniques to non-linear time-dependent problems, we present a test case of a two-dimensional viscous Burgers equation with parametrized initial data.

description: Scandenin and 4'-O-methylderrone were isolated from the ethanol extract of the roots and dichloromethane extract of the leaves of Deguelia costata (Benth.) A.M.G. Azevedo & R.A. Camargo, respectively. These compounds and their extracts had their antiprotozoal, antibacterial, antifungal, and cytotoxic activities tested. All samples were active for amastigotes of the T. cruzi, with EC50 values varying from 34.5 to 9.8 µg mL−1. The 4'-O-methylderrone and scandenin showed better leishmanicidal action against the promastigote of L. amazonensis, with EC50 of 43.3 and 45.9 µg mL−1, respectively, when compared to their extracts. All extracts and scandenin showed activities against Staphylococcus sp, Bacillus sp, and Candida sp. The compounds did not show cytotoxicity on rat macrophages. As confirmed by spectroscopic analyses, the extracts are rich in phenolics, mainly isoflavonoids. The study of D. costata is a promising strategy for discovering isoflavones and 4-hydroxy-3-phenylcoumarins with antiprotozoal, antibacterial, and antifungal activities.

description: The purpose of this paper is to discuss the dangers of discrimination and hate speech in Algeria. The Algerian state has addressed hate speech, which threatens democratic values, social stability, and peace, by promulgating Law 20-05 on the prevention and fight against discrimination and hate speech which calls for the establishment of a national observatory to deal with the issue, amending and supplementing the penal code ordinance n° 66-156. According to the findings of this study, preventing hate speech from expanding to dangerous levels is an urgent matter that the national observatory must address while battling discrimination, hatred, and violence in Algerian society. However, many activists expressed concern that the bill criminalizing racism and hatred would be used as an excuse to further restrict freedom of expression and creativity, as well as to emphasize control over historical readings and literary contributions
Toward a realistic Buchdahl limit in f(R) theories of gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The so-called Buchdahl limit is not yet fully understood in the context of theories of gravity beyond the Einsteinian framework. In this investigation, we generalize this limit for the case of static, spherically-symmetric, relativistic compact stars in f(R) theories of gravity within the metric formalism. We present a comprehensive analysis that ensures regularity, thermodynamic stability, fulfillment of all required junction conditions, recovery of the Newtonian potential at long distances and a correct extraction of the asymptotic mass. Our results are exemplified for the f(R)=R+ alpha R^2 Starobinsky model and several realistic equations of state describing neutron-star matter. We also compare these results with the case of compact stars immersed ad hoc in an Schwarzschild exterior vacuum, although this scenario does not fulfill all necessary f(R) junction conditions. To test the validity of viable f(R) models, we show that such stars can indeed host additional energetic content, so their gravitational redshift can be greater than 2, which is prohibited in General Relativity.

description: The aim of the present study was to explore Cassia fistula L. seed mucilage as a natural polymer in controlled release floating drug delivery system. First, seed mucilage was extracted and evaluated for phytochemical screening, solubility studies, swelling index, viscosity and surface tension. Then, Atenolol floating systems were prepared with and without the C. fistula L. seed mucilage by direct compression method. Phytochemical screening resulted from the presence of secondary metabolite carbohydrates, glycosides, flavonoids and phenolic compounds in good amounts. Results of hardness, friability, drug content and swelling index were satisfactory. The floating behaviour can increase the gastric residence time and eventually improve the bioavailability of the drug as evidence from in vitro buoyancy and dissolution studies. Interestingly, developed floating system showed remarkable increase in dissolution. Conclusively, the results suggest that developed Atenolol floating system with C. fistula L. seed mucilage demonstrate interesting attributes to be explored for potential pharmaceutical application.

In particular, we focus on the case when the Poisson bracket arises from a noncommutative symplectic form. The formalism is then applied to the study of the Calogero-Moser and Gibbons-Hermsen integrable systems. In the former case, we give a new interpretation of the bihamiltonian reduction performed in [3].

description: Quantum spin models with spatially dependent interactions, known as compass models, play an important role in the study of frustrated quantum magnetism. One example is the Kitaev model on the honeycomb lattice with spin-liquid ground states and anyonic excitations. Another example is the geometrically frustrated quantum $120^\circ$ model on the same lattice whose ground state has not been unambiguously established. To generalize the Kitaev model beyond the exactly solvable limit and connect it with other compass models, we propose a new model, dubbed "the tripod model", which contains a continuum of compass-type models. It smoothly interpolates the Ising model, the Kitaev model, and the quantum $120^\circ$ model by tuning a single parameter $θ'$, the angle between the three legs of a tripod in the spin space. Hence it not only unifies three paradigmatic spin models, but also enables the study of their quantum phase transitions. We obtain the phase diagram of the tripod model numerically by tensor networks in the thermodynamic limit. We show that the ground state of the quantum $120^\circ$ model has long-range dimer order. Moreover, we find an extended spin-disordered (spin-liquid) phase between the dimer phase and an antiferromagnetic phase. The unification and solution of a continuum of frustrated spin models as outline here may be useful to exploring new domains of other quantum spin or orbital models.

description: The aim of this study was to investigate the anticancer effect of Adenophora triphylla var. japonica (AT) root extract on human non-small cell lung cancer (NSCLC) cells and the mechanism involved in such effect. Among three fractions of AT root extract, hexane fraction (HAT) significantly decreased the proliferation of NSCLC cells. Besides, HAT treatment dose-dependently inhibited colony formation of NSCLC cells. These effects were associated with apoptosis induction evidenced by increased chromatin condensation, accumulation of sub-G1 DNA content and annexin V-positive cells, and enhanced expression of apoptotic proteins, including cleaved-caspases and cleaved-poly (ADP-ribose) polymerase (PARP). Notably, phosphorylation levels of signal transducer and activator of transcription 3 (STAT3) and Src were decreased by HAT. Transfection with STAT3 or Src for constitutive activation reversed the anti-proliferative effect of HAT on H1299 cells. Taken together, our findings suggest that HAT-induced apoptosis in NSCLC cells is mediated by inhibition of Src/STAT3 pathway.

description: This paper has the dual purpose of outlining the case history related to paralepsis in literary texts, highlighting the different possibilities of application and the narrative effects that derive in any case towards a transgressive fantastic alteration, and of trying to update the referential system drawn by Genette in 1972. For that, we will draw on some postulates and principles of linguistics and cognitive narratology, applying them to two specific stories by Michele Mari, Josef K. and Lamento del guerriero, when we will show how unexpected informations offered by a particular character (bottom-up vertical paralepsis and internal horizontal paralepsis) produce metaleptic shifts that dis-locate and re-locate the reading around different attractors that transgress the fictional logic (Remorini 2023).

The obtained nonlocal corrections to DMFT yield a decrease of the Curie temperature of the $α$ phase, leading to an agreement with its experimental value. We show that the corresponding nonlocal corrections to the energy of the $α$ phase are crucially important to obtain the proximity of energies of $α$ and $γ$ phases in the vicinity of the iron $α$-$γ$ transformation.

description: One of the major open questions in matroid theory asks whether the $h$-vector $(h_0,h_1,\ldots,h_s)$ of the broken circuit complex of a matroid $M$ satisfies the following inequalities: $$ h_0\leq h_1\leq \cdots\leq h_{\lfloor s/2\rfloor} \quad \text{and}\qua h_i\le h_{s-i}\ \text{ for }\ 0\leq i \leq \lfloor s/2\rfloor. $$ This paper affirmatively answers the question for matroids that are representable over a field of characteristic zero.

Le Glypticus sidcatus, espèce bien caractérisée, est, en général, peu répandu. On ne l'a cité, en France, que de Morestel (Isère), et de la vigne Droguet, près Chambéry. Un exemplaire très bien conservé a été recueilli à Sylau, près Nantua, dans les couches séquaniennes, par M. Derriaz, qui l'a donné au Musée de Genève. Cet individu, parfaitement typique, appartient à une variété déjà signalée à Nattheim. La surface est plus tuberculeuse; les deux sillons verticaux caractéristiques des aires interambulacraires sont très peu définis; et les granules sont relativement abondants, généralement allongés dans un sens ou dans l'autre, et disposés en petites séries transverses assez régulières. On compte toujours trois tubercules dans chacune des deux séries qui occupent la face inférieure des aires ambula- craires et interambulacraires. Le Pseadodiadema florescens Ag. a été aussi recueilli dans la même localité.

description: The discovery of many strongly correlated metallic phases has inspired different routes to generalize or go beyond the celebrated Landau Fermi liquid theory. To this end, from universal consideration of symmetries and anomalies, Else, Thorngren and Senthil (ETS) have introduced a class of theories called ersatz Fermi liquids which possess a Fermi surface and satisfy a generalized Luttinger's theorem. In this work, we view all such fermion liquids obeying the Luttinger theorem as incompressible quantum Hall liquids in higher-dimensional phase space and use it as the starting point to derive their effective low-energy field theory. The noncommutativity of phase space motivates us to use the Seiberg-Witten map to derive the field theory in an ordinary (commutative) space and naturally leads to terms that correspond to the correct topological Chern-Simons action postulated by ETS in one, two, and three dimensions. Additionally, our approach also reproduces all the non-topological terms that characterize important contributions to the response, including the semiclassical equations of motion. Finally, our derivations of Chern-Simons terms from the Seiberg-Witten map also verify a longstanding conjecture in noncommutative field theory.

$E_6$ Inspired SUSY Benchmarks, Dark Matter Relic Density and a 125 GeV Higgs

description: We explore the relic density of dark matter and the particle spectrum within a constrained version of an $E_6$ inspired SUSY model with an extra $U(1)_N$ gauge symmetry. In this model a single exact custodial symmetry forbids tree-level flavor-changing transitions and the most dangerous baryon and lepton number violating operators. We present a set of benchmark points showing scenarios that have a SM-like Higgs mass of 125 GeV and sparticle masses above the LHC limits. They lead to striking new physics signatures which may be observed during run II of the LHC and can distinguish this model from the simplest SUSY extensions of the SM. At the same time these benchmark scenarios are consistent with the measured dark matter abundance and necessarily lead to large dark matter direct detection cross sections close to current limits and observable soon at the XENON1T experiment.

description: This study focused on the synthesis of 1,3-dihydroxyxanthone (1) and its new derivatives with alkyl (2a–2f), alkenyl (2 g–2k), alkynyl (2 l–2n), and alkylated phenyl (2o–2r) groups at C3 position. The structures of these compounds were confirmed by MS, NMR, and FTIR spectroscopic data. All the substituted xanthones (2a–2r) showed significantly stronger acetylcholinesterase (AChE) inhibitory activities than 1. Compounds 2g and 2j exhibited the strongest activities with the IC50 values of 20.8 and 21.5 μM and their enzyme kinetic analyses indicated a mixed-mode inhibition. Molecular docking study revealed that 2g binds favourably to the active site of AChE via π–π stacking and hydrogen bonding from the xanthone ring, in addition to π-alkyl interaction from the substituent group. These xanthone derivatives are potential lead compounds to be further developed into Alzheimer’s disease drugs.
Optimal inference strategies and their implications for the linear noise approximation

description: We study the information loss of a class of inference strategies that is solely based on time averaging. For an array of independent binary sensors (e.g., receptors, single electron transistors) measuring a weak random signal (e.g., ligand concentration, gate voltage) this information loss is up to 0.5 bit per measurement irrespective of the number of sensors. We derive a condition related to the local detailed balance relation that determines whether or not such a loss of information occurs. Specifically, if the free energy difference arising from the signal is symmetrically distributed among the forward and backward rates, time integration mechanisms will capture the full information about the signal. As an implication, for the linear noise approximation, we can identify the same loss of information, arising from its inherent simplification of the dynamics.

description: The conducting gas that forms at the interface between LaAlO$_3$ and SrTiO$_3$ has proven to be a fertile playground for a wide variety of physical phenomena. The bulk of previous research has focused on the (001) and (110) crystal orientations. Here we report detailed measurements of the low-temperature electrical properties of (111) LAO/STO interface samples. We find that the low-temperature electrical transport properties are highly anisotropic, in that they differ significantly along two mutually orthogonal crystal orientations at the interface. While anisotropy in the resistivity has been reported in some (001) samples and in (110) samples, the anisotropy in the (111) samples reported here is much stronger, and also manifests itself in the Hall coefficient as well as the capacitance. In addition, the anisotropy is not present at room temperature and at liquid nitrogen temperatures, but only at liquid helium temperatures and below. The anisotropy is accentuated by exposure to ultraviolet light, which disproportionately affects transport along one surface crystal direction. Furthermore, analysis of the low-temperature Hall coefficient and the capacitance as a function of back gate voltage indicates that in addition to electrons, holes contribute to the electrical transport.

description: Motivation: Structural heterogeneity in single-particle cryo-electron microscopy (cryo-EM) data represents a major challenge for high-resolution structure determination. Unsupervised classification may serve as the first step in the assessment of structural heterogeneity. Traditional algorithms for unsupervised classification, such as K-means clustering and maximum likelihood optimization, may classify images into wrong classes with decreasing signal-to-noise-ratio (SNR) in the image data, yet demand increased cost in computation. Overcoming these limitations requires further development on clustering algorithms for high-performance cryo-EM data analysis. Results: Here we introduce a statistical manifold learning algorithm for unsupervised single-particle deep clustering. We show that statistical manifold learning improves classification accuracy by about 40% in the absence of input references for lower SNR data. Applications to several experimental datasets suggest that our deep clustering approach can detect subtle structural difference among classes. Through code optimization over the Intel high-performance computing (HPC) processors, our software implementation can generate thousands of reference-free class averages within several hours from hundreds of thousands of single-particle cryo-EM images, which allows significant improvement in ab initio 3D reconstruction resolution and quality. Our approach has been successfully applied in several structural determination projects. We expect that it provides a powerful computational tool in analyzing highly heterogeneous structural data and assisting in computational purification of single-particle datasets for high-resolution reconstruction.

Potential of a singlet scalar enhanced Standard Model

description: We investigate the parameter space of the Standard Model enhanced by a gauge singlet real scalar $S$. Taking into account all the theoretical and experimental constraints, we show the allowed parameter space for two different types of such singlet-enhanced Standard Model. For the first case, the scalar potential has an explicit $Z_2$-symmetry, and may lead to a dark matter candidate under certain conditions. For the second case, the scalar potential does not respect any $Z_2$. This is again divided into two subcategories: one where the Standard Model vacuum is stable, and one where it is unstable and can decay into a deeper minimum. We show how the parameters in the scalar potential control the range of validity of all these models. Finally, we show the effect of one-loop correction on the positions and depths of the minima of the potential.
