The emptiness of voids: yet another over-abundance problem for the LCDM model

description: We study the luminosity function, the peculiar velocities, and the sizes of voids in the Local Volume (LV) in observational samples of galaxies which contain galaxies down to MB=-10-12 within the distance 4-8Mpc. Comparing the results with the predictions of the standard cosmological LCDM model, we find that the theory faces a sever problem: it predicts a factor of ten more dwarf haloes as compared with the observed number of dwarf galaxies. In the LV we identify voids with sizes ranging from 1 to 4.5Mpc and compare the observational distribution of void sizes with the voids in very high resolution simulations of the LCDM model with WMAP1 and WMAP3 parameters. The theoretical void function matches the observations remarkably well only if we use haloes with circular velocities Vc larger than 40-45 km/s (Mvir=(1-2)e10msun) for models with with sigma8 = 0.9 and Vc>35km/s (Mvir=(6-8)e9msun) for sigma8 = 0.75. We exclude the possibility that in the LCDM model haloes with circular velocities < 35km/s can host galaxies as bright as MB=-12: there are too many small haloes in the LCDM model resulting in voids being too small as compared with the observations. The problem is that many of the observed dwarf galaxies have HI rotational velocities below 25km/s that strictly contradicts the LCDM predictions. Thus, the LCDM model faces the same overabundance problem, which it had with the number of satellites in the LG. We also estimate the rms deviations from the Hubble flow sigmaH and find that in most of our model LV-candidates the rms peculiar velocities are consistent with observational values sigmaH=50km/s for distances less than 3Mpc and sigmaH=80km/s for distances less than 8Mpc. At distances 4 (8) Mpc, the observed overdensities of galaxies are 3.5-5.5 (1.3-1.6) -- significantly larger than typically assumed.

description: The family of monolayer two-dimensional (2D) materials hosts a wide range of interesting phenomena, including superconductivity, charge density waves, topological states and ferromagnetism, but direct evidence for antiferromagnetism in the monolayer has been lacking. Nevertheless, antiferromagnets have attracted enormous interest recently in spintronics due to the absence of stray fields and their terahertz resonant frequency. Despite the great advantages of antiferromagnetic spintronics, controlling and detecting Néel vectors have been limited in bulk materials. In this work, we developed a sensitive second harmonic generation (SHG) microscope and detected long-range Néel antiferromagnetic (AFM) order and Néel vector switching down to the monolayer in MnPSe$_3$. Temperature-dependent SHG measurement in repetitive thermal cooling surprisingly collapses into two curves, which correspond to the switching of an Ising type Néel vector reversed by the time-reversal operation, instead of a six-state clock ground state expected from the threefold rotation symmetry in the structure. We imaged the spatial distribution of the Néel vectors across samples and rotated them by an arbitrary angle irrespective of the lattice in the sample plane by applying strain. By studying both a Landau theory and a microscopic model that couples strain to nearest-neighbor exchange, we conclude that the phase transition of the XY model in the presence of strain falls into the Ising universality class instead of the XY one, which could explain the extreme strain tunability. Finally, we found that the 180° AFM domain walls are highly mobile down to the monolayer after thermal cycles, paving the way for future control of the antiferromagnetic domains by strain or external fields on demand for ultra-compact 2D AFM terahertz spintronics.

description: Cu-NH3 bearing effluents arise from electroplating and metal extraction industries, requiring innovative and sustainable Cu recovery technologies to reduce their adverse environmental impact. CO32- and Zn are often co-occurring, and thus, selective Cu recovery from these complex liquid streams is required for economic viability. This study assessed 23 sustainable biosorbents classified as tannin-rich, lignin-rich, chitosan/chitin, dead biomass, macroalgae or biochar for their Cu adsorption capacity and selectivity in a complex NH3-bearing bioleachate. Under a preliminary screen with 12 mM Cu in 1 M ammoniacal solution, most biosorbents showed optimal Cu adsorption at pH 11, with pinecone remarkably showing high removal efficiencies (up to 68%) at all tested pH values. Further refinements on select biosorbents with pH, contact time, and presence of NH3, Zn and CO32- showed again that pinecone has a high maximum adsorption capacity (1.07 mmol g-1), worked over pH 5-12 and was Cu-selective with 3.97 selectivity quotient (KCu/Zn). Importantly, pinecone performance was maintained in a real Cu/NH3/Zn/CO32- bioleachate, with 69.4% Cu removal efficiency. Unlike synthetic adsorbents, pinecones require no pre-treatment, which together with its abundance, selectivity, and efficiency without the need for prior NH3 removal, makes it a competitive and sustainable Cu biosorbent for complex Cu-NH3 bearing streams. Overall, this study demonstrated the potential of integrating bioleaching and biosorption as a clean Cu recovery technology utilizing only sustainable resources (i.e., bio-lixiviant and biosorbents). This presents a closed-loop approach to Cu extraction and recovery from wastes, thus effectively addressing elemental sustainability.

description: We report on the single crystal growth of the ferromagnetic Kondo lattice system CeRuPO using a Sn flux method. Magnetic susceptibility and electrical resistivity measurements indicate strong anisotropy of this structurally layered compound. They evidence that the magnetic moments order ferromagnetically along the c-direction of the tetragonal unit cell, whereas the crystal electric field (CEF) anisotropy favors the ab-plane. Therefore, CeRuPO presents the unusual case within rare earth systems, where the anisotropy of the interionic exchange interaction overcomes the single ion anisotropy due to the CEF interaction.

description: We discuss Bohmian paths of the two-level atoms moving in a waveguide through an external resonance-producing field, perpendicular to the waveguide, and localized in a region of finite diameter. The time spent by a particle in a potential region is not well-defined in the standard quantum mechanics, but it is well-defined in the Bohmian mechanics. Bohm's theory is used for calculating the average time spent by a transmitted particle inside the field region and the arrival-time distributions at the edges of the field region. Using the Runge-Kutta method for the integration of the guidance law, some Bohmian trajectories were also calculated. Numerical results are presented for the special case of a Gaussian wave packet.

Tertiary phosphine complexes of zirconium(IV) and hafnium(IV)
Creators: name: Carter, Alan
Publisher: name: University of British Columbia
Year: 2010

description: The tetra-halides of zirconium and hafnium were reacted with one equivalent of the potentially tridentate hybrid ligand, N(SiMe₂CH₂PR₂)2-, (R = Me, i-Pr, t-Bu) to generate the corresponding mono-ligand complexes MCl₃{N(SiMe₂CH₂PR₂)₂), (M = Zr, Hf). Based on the results obtained from the solution spectroscopic data and the single crystal X-ray diffraction analyses of HfCI₃{N(SiMe₂CH₂PMe₂)₂> and ZrCl₃{N(SiMe₂CH₂P(i-Pr)₂)₂) the stereochemistries of all the MCI ₃{N(SiMe ₂CH₂PR₂) ₂) complexes were found to be meridional in solution, but both facial and meridional geometries were displayed in the solid state dependent on the ligand. The mono-ligand derivatives served as useful starting materials for the generation of zirconium- and hafnium-carbon bonds. Thus the addition of three equivalents of MeMgCl to one equivalent of MCl₃{N(SiMe₂CH₂PR₂)₂} generated the trimethyl complexes M(CH₃)₃{N(SiMe₂CH₂PR₂)₂}. When two equivalents of MeMgCl was added to the mono-ligand complexes, an inseparable mixture of the monomethyl and dimethyl derivatives was obtained. The stereochemistry of Hf(CH₃)₃{N(SiMe₂CH₂PMe₂)₂} is facial in the solid state but displays unusual fluxional behaviour in solution. This behaviour is observed for all the trimethyl derivatives as a consequence of the dissociative nature of the phosphine donors. Several possible rearrangement pathways for these compounds are discussed in an attempt to interpret this behaviour in solution.

description: I would like to thank Junk and Lyons (arXiv:2009.06864) for beginning a discussion about replication in high-energy physics (HEP). Junk and Lyons ultimately argue that HEP learned its lessons the hard way through past failures and that other fields could learn from our procedures. They emphasize that experimental collaborations would risk their legacies were they to make a type-1 error in a search for new physics and outline the vigilance taken to avoid one, such as data blinding and a strict $5σ$ threshold. The discussion, however, ignores an elephant in the room: there are regularly anomalies in searches for new physics that result in substantial scientific activity but don't replicate with more data.

description: The design of sensor networks capable of reaching a consensus on a globally optimal decision test, without the need for a fusion center, is a problem that has received considerable attention in the last years. Many consensus algorithms have been proposed, with convergence conditions depending on the graph describing the interaction among the nodes. In most works, the graph is undirected and there are no propagation delays. Only recently, the analysis has been extended to consensus algorithms incorporating propagation delays. In this work, we propose a consensus algorithm able to converge to a globally optimal decision statistic, using a wideband wireless network, governed by a fairly simple MAC mechanism, where each link is a multipath, frequency-selective, channel. The main contribution of the paper is to derive necessary and sufficient conditions on the network topology and sufficient conditions on the channel transfer functions guaranteeing the exponential convergence of the consensus algorithm to a globally optimal decision value, for any bounded delay condition.

description: We address the issue whether the data on optical conductivity and Raman scattering in electron-doped cuprates below $T_c$ support the idea that the $d-$wave gap in these materials is non-monotonic along the Fermi surface. We calculate the conductivity and Raman intensity for elastic scattering, and find that a non-monotonic gap gives rise to several specific features in optical and Raman response functions. We argue that all these features are present in the experimental data on Nd$_{2-x}$Ce$_{x}$CuO$_4$ and Pr$_{2-x}$Ce$_{x}$CuO$_4$ compounds.

description: We derive a class of generalized statistics, unifying the Bose and Fermi ones, that describe any system where the first-occupation energies or probabilities are different from subsequent ones, as in presence of thresholds, saturation, or aging. The statistics completely describe the structural correlations of weighted networks, which turn out to be stronger than expected and to determine significant topological biases. Our results show that the null behavior of weighted networks is different from what previously believed, and that a systematic redefinition of weighted properties is necessary.

description: We report the first experimental observation of bright EPR beams produced by a type-II optical parametric oscillator operating above threshold at frequency degeneracy. The degenerate operation is obtained by introducing a birefringent plate inside the cavity resulting in phase locking. After filtering the pump noise, which plays a critical role, continuous-variable EPR correlations between the orthogonally polarized signal and idler beams are demonstrated.

description: One of the most promising tracers of the Galactic potential in the halo region are stellar streams. However, individual stream fits can be limited by systematic biases. To study these individual stream systematics, we fit streams in Milky Way-like galaxies from FIRE cosmological galaxy formation simulations with an analytic gravitational potential by maximizing the clustering of stream stars in action space. We show that for coherent streams the quality of the constraints depends on the orbital phase of the observed stream stars, despite the fact that the phase information is discarded in action-clustering methods. Streams on intermediate phases give the most accurate results, whereas pericentre streams can be highly biased. This behaviour is tied to the amount of correlation present between positions and momenta in each stream's data: weak correlation in pericentre streams prohibits efficient differentiation between potentials, while strong correlation in intermediate streams promotes it. Although simultaneous fitting of multiple streams is generally prescribed as the remedy to combat individual stream biases, we find that combining multiple pericentric streams is not enough to yield a bias-free result. We finally show that adopting the two-component Stäckel model does not fundamentally induce a biased mass estimate. With our full data set of two multi-wrap streams, we recovered the true rotation curve of the simulated galaxy within $12\%$ over the entire range of radii covered by our set of stars (10 - 176 kpc) and within $6.5\%$ between the 5 and 95-percentile distance range (23 - 109 kpc).

Synthesis of [beta]-keto lactones and the synthetic consequences of the conformational preferences of 14-membered lactones
Creators: name: Ounsworth, James Paul
Publisher: name: University of British Columbia
Year: 2010

description: The preparation of the β-keto lactones 1̲9̲ via intramolecular alcoholysis of hydroxy Meldrum's acid derivatives was examined. Good yields of the 6- and 14-membered compounds were obtained, but the method was completely unsuccessful for medium-size rings. An investigation was conducted on the conformational preference of substituted 14-merabered lactones with a view to understanding the stereochemical consequences of the reactions of these compounds. The conformational preferences of simple 14-membered cyclic compounds were first determined. These preferences are described in terms of steric and electronic interactions, with the support of computer-calculated steric energies. A number of 14-membered lactones were prepared, beginning with the β-keto lactone 3-oxo-13-tetradecanolide (1̲3̲8̲). Hydride reduction of (1̲3̲8̲) gave the diastereomeric alcohols 1̲4̲6̲ and 1̲4̲7̲, which were then elaborated to give a series of derivatives. The stereochemistry and conformations of these compounds were determined by X-ray crystallography and/or nmr analysis. The preferred conformation was found to be Dale's [3434] diamond lattice model. The relative rates of reaction were determined for several reactions of the alcohols 1̲4̲6̲ and 1̲4̲7̲ and for one reaction of the corresponding acetates. The conformational effects were found to be much smaller than those observed in 6-merabered rings. Explanations of this difference are given. The preparation of the ⍺, β-unsaturated lactones 1̲6̲3̲ and 1̲6̲4̲, the β-methyl-⍺, β-unsaturated lactones 1̲8̲5̲ and 1̲8̲̲6̲̲, the dimethyl lactones 1̲5̲4̲ and 1̲5̲5̲ and the epoxides 1̲9̲7̲ and 1̲9̲8̲ are described. The resulting geometry of double bonds and the stereochemistry of substituents are explained in terms of conformational preferences. [Formula Omitted]

description: A dynamically-modulated ring system with frequency as a synthetic dimension has been shown to be a powerful platform to do quantum simulation and explore novel optical phenomena. Here we propose synthetic honeycomb lattice in a one-dimensional ring array under dynamic modulations, with the extra dimension being the frequency of light. Such system is highly re-configurable with modulation. Various physical phenomena associated with graphene including Klein tunneling, valley-dependent edge states, effective magnetic field, as well as valley-dependent Lorentz force can be simulated in this lattice, which exhibits important potentials for manipulating photons in different ways. Our work unveils a new platform for constructing the honeycomb lattice in a synthetic space, which holds complex functionalities and could be important for optical signal processing as well as quantum computing.

There are indications that our formulas hold more generally.

description: Differential flows among different ion species are often observed in the solar wind, and such ion differential flows can provide the free energy to drive Alfvén/ion-cyclotron and fast-magnetosonic/whistler instabilities. Previous works mainly focused on ion beam instability under the parameters representative of the solar wind nearby 1 au. In this paper we further study proton beam instability using the radial models of the magnetic field and plasma parameters in the inner heliosphere. We explore a comprehensive distribution of proton beam instability as functions of the heliocentric distance and the beam speed. We also perform a detailed analysis of the energy transfer between unstable waves and particles and quantify how much the free energy of the proton beam flows into unstable waves and other kinds of particle species (i.e., proton core, alpha particle, and electron). This work clarifies that both parallel and perpendicular electric fields are responsible for the excitation of oblique Alfvén/ion-cyclotron and oblique fast-magnetosonic/whistler instabilities. Moreover, this work proposes an effective growth length to estimate whether the instability is efficiently excited or not. It shows that oblique Alfvén/ion-cyclotron instability, oblique fast-magnetosonic/whistler instability, and oblique Alfvén/ion-beam instability can be efficiently driven by proton beams drifting at the speed $\sim$ 600-1300 km s$^{-1}$ in the solar atmosphere. In particular, oblique Alfvén/ion-cyclotron waves driven in the solar atmosphere can be significantly damped therein, leading to the solar corona heating. These results are helpful for understanding proton beam dynamics in the inner heliosphere and can be verified through in situ satellite measurements.

description: We study the collective dynamics of groups of whirligig beetles Dineutus discolor (Coleoptera: Gyrinidae) swimming freely on the surface of water. We extract individual trajectories for each beetle, including positions and orientations, and use this to discover (i) a density dependent speed scaling like $v\simρ^{-ν}$ with $ν\approx0.4$ over two orders of magnitude in density (ii) an inertial delay for velocity alignment of $\sim 13$ ms and (iii) coexisting high and low density phases, consistent with motility induced phase separation (MIPS). We modify a standard active brownian particle (ABP) model to a Corralled ABP (CABP) model that functions in open space by incorporating a density-dependent reorientation of the beetles, towards the cluster. We use our new model to test our hypothesis that a MIPS (or a MIPS like effect) can explain the co-occurrence of high and low density phases we see in our data. The fitted model then successfully recovers a MIPS-like condensed phase for $N=200$ and the absence of such a phase for smaller group sizes $N=50,100$.

description: Transport phenomena at the nanoscale are of interest due to the presence of both quantum and classical behavior. In this work, we demonstrate that quantum transport efficiency can be enhanced by a dynamical interplay of the system Hamiltonian with pure dephasing induced by a fluctuating environment. This is in contrast to fully coherent hopping that leads to localization in disordered systems, and to highly incoherent transfer that is eventually suppressed by the quantum Zeno effect. We study these phenomena in the Fenna-Matthews-Olson protein complex as a prototype for larger photosynthetic energy transfer systems. We also show that disordered binary tree structures exhibit enhanced transport in the presence of dephasing.

description: Amplitudes of the form $γ^*(q^2)\to γP_1P_2$ appear as sub-processes in the computation of the muon $g-2$. We test a proposed theoretical modelling against very precise experimental measurements by the KLOE collaboration at $q^2=m^2_ϕ$. Starting from an exact parameter-free dispersive representation for the $S$-wave satisfying QCD asymptotic constraints and Low's soft photon theorem we derive, in an effective theory spirit, a two-channel Omnès integral representation which involves two subtraction parameters. The discontinuities along the left-hand cuts which, for timelike virtualities, extend both on the real axis and into the complex plane are saturated by the contributions from the light vector mesons. In the case of $P_1P_2=πη$, we show that a very good fit of the KLOE data can be achieved with two real parameters, using a $T$-matrix previously determined from $γγ$ scattering data. This indicates a good compatibility between the two data sets and confirms the validity of the $T$-matrix. The resulting amplitude is also found to be compatible with the chiral soft pion theorem. Applications to the $I=1$ scalar form factors and to the $a_0(980)$ resonance complex pole are presented.

description: Hintergrund und Ziele Eine effiziente Therapie für die Beschwerden von Endometriosepatientinnen ist seit Jahren Gegenstand intensiver Forschung. Trotz zahlreicher etablierter Therapien in Form von Hormonpräparaten oder chirurgischer Sanierung erfahren bislang viele Patientinnen hierdurch keine ausreichende Symptomlinderung. Die Analyse des Bedarfs, der Akzeptanz und der Anwendung möglicher Therapien aus dem Bereich der Komplementär- und Alternativmedizin für Endometriosepatientinnen war Gegenstand dieser Arbeit. Methoden Um diese Fragestellungen zu untersuchen, wurde eine multizentrische Kohortenstudie konzipiert, an der zwei Endometriosezentren im Südwesten Deutschlands teilgenommen haben. Die Kontaktaufnahme mit den Patientinnen erfolgte postalisch oder per E-Mail. Die Daten des sich so ergebenen Gesamtkollektivs wurden mit Hilfe von deskriptiver Statistik hinsichtlich der oben genannten Fragestellungen untersucht. Zur Datenerfassung diente das Online-Umfragetool LimeSurvey Professional. Die Datenanalyse erfolgte durch die Statistik- und Analyse-Software IBM SPSS Statistics Version 26 und 27 (IBM, Armonk, New York, USA). Ergebnisse und Beobachtungen Es wurden insgesamt 592 Patientinnen kontaktiert. Von diesen Patientinnen haben wir 139 Rückmeldungen bekommen, von denen 114 in die Auswertung aufgenommen werden konnten. Auf Patientencharakteristika wird in der beigefügten Veröffentlichung ausführlich eingegangen. Die wichtigsten Ergebnisse hinsichtlich der Kernfragen dieser Arbeit waren, dass eine Vielzahl der Patientinnen, bei denen bereits chirurgische und/oder hormonelle Therapieoptionen zum Einsatz kommen/kamen, großes Interesse an der zusätzlichen Anwendung von Therapien aus dem komplementären und alternativen Formenkreis hat. Außerdem wenden bereits viele von ihnen CAM-Methoden zur Symptomlinderung und Verbesserung der physischen und psychischen Gesundheit an, obwohl in den meisten Fällen ein ausführliches Wissen über Effizienz, Nebenwirkungen und Wirkungsweise einzelner Methoden fehlt. Schlussfolgerungen und Diskussion Der Bedarf an weiterer Forschung im Bereich der Komplementär- und Alternativmedizin mit speziellem Fokus auf Endometriosepatientinnen ist sehr hoch. Auch dem Defizit an ausreichenden Informationen zu diesem Thema sollte durch ausführliche und methodisch hochwertige wissenschaftliche Studien begegnet werden, damit es den betroffenen Patientinnen möglich ist, diesbezüglich valide Entscheidungen treffen zu können. Die geringe Populationsgröße der Studie erschwert eine direkte Übertragung der Studienergebnisse auf das Gesamtkollektiv der Endometriosepatientinnen in Deutschland. Daher sollten ausführliche Kohortenstudien mit größeren Fall-zahlen an diese Studie angeschlossen werden.
Confocal microscopy of colloidal particles: towards reliable, optimum coordinates

description: Over the last decade, the light microscope has become increasingly useful as a quantitative tool for studying colloidal systems. The ability to obtain particle coordinates in bulk samples from micrographs is particularly appealing. In this paper we review and extend methods for optimal image formation of colloidal samples, which is vital for particle coordinates of the highest accuracy, and for extracting the most reliable coordinates from these images. We discuss in depth the accuracy of the coordinates, which is sensitive to the details of the colloidal system and the imaging system. Moreover, this accuracy can vary between particles, particularly in dense systems. We introduce a previously unreported error estimate and use it to develop an iterative method for finding particle coordinates. This individual-particle accuracy assessment also allows comparison between particle locations obtained from different experiments. Though aimed primarily at confocal microscopy studies of colloidal systems, the methods outlined here should transfer readily to many other feature extraction problems, especially where features may overlap one another.

description: 3C 84 (NGC 1275) is the bright radio core of the Perseus Cluster. Even in the absence of strong relativistic effects, the source has been detected at Gamma-rays up to TeV energies. Despite its intensive study, the physical processes responsible for the high-energy emission in the source remain unanswered. We present a detailed kinematics study of the source and its connection to Gamma-ray emission. The sub-parsec scale radio structure is dominated by slow-moving features in both the eastern and western lanes of the jet. The jet appears to have accelerated to its maximum speed within less than 125 000 gravitational radii. The fastest reliably detected speed in the jet was ~0.9 c. This leads to a minimum Lorentz factor of ~1.35. Our analysis suggests the presence of multiple high-energy sites in the source. If Gamma-rays are associated with kinematic changes in the jet, they are being produced in both eastern and western lanes in the jet. Three Gamma-ray flares are contemporaneous with epochs where the slowly moving emission region splits into two sub-regions. We estimate the significance of these events being associated as ~2-3 sigma. We tested our results against theoretical predictions for magnetic reconnection-induced mini-jets and turbulence and find them compatible.

description: The Einstein equivalence principle in the electromagnetic sector can be violated in modifications of gravity theory generated by a multiplicative coupling of a scalar field to the electromagnetic Lagrangian. In such theories, deviations of the standard result for the cosmic distance duality relation, and a variation of the fine structure constant are expected and are unequivocally intertwined. In this paper, we search for these possible cosmological signatures by using galaxy cluster gas mass fraction measurements and cosmic chronometers. No significant departure from general relativity is found regardless of our assumptions about cosmic curvature or a possible depletion factor evolution in cluster measurements.
