description: The unitarity method for calculating one-loop amplitudes provides algorithms of polynomial complexity. This is primarily beneficial for the computation of multi-leg one loop amplitudes and it is therefore of great interest to develop a numerical implementation of the unitarity method. We describe a recently-developed, efficient, semi-numerical unitarity method for the computation of the cut-constructible part of one-loop amplitudes.

description: There have been many theoretical models constructed which aim to explain the neutrino masses and mixing patterns. While many of the models will be eliminated once more accurate determinations of the mixing parameters, especially $\sin^2 2θ_{13}$, are obtained, charged lepton flavor violation (LFV) experiments are able to differentiate even further among the models. In this paper, we investigate various rare LFV processes, such as $\ell_{i} \to \ell_{j} + γ$ and $μ-e$ conversion, in five predictive supersymmetric (SUSY) SO(10) models and their allowed soft-SUSY breaking parameter space in the constrained minimal SUSY standard model. Utilizing the Wilkinson Microwave Anisotropy Probe dark matter constraints, we obtain lower bounds on the branching ratios of these rare processes and find that at least three of the five models we consider give rise to predictions for $μ\to e + γ$ that will be tested by the MEG Collaboration at PSI. In addition, the next generation $μ-e$ conversion experiment has sensitivity to the predictions of all five models, making it an even more robust way to test these models. While generic studies have emphasized the dependence of the branching ratios of these rare processes on the reactor neutrino angle $θ_{13}$ and the mass of the heaviest right-handed neutrino $M_3$, we find very massive $M_3$ is more significant than large $θ_{13}$ in leading to branching ratios near to the present upper limits.

description: Reading is one of the most common everyday activities, yet research elucidating how affective influence reading processes and outcomes is sparse with inconsistent results. To investigate this question, we randomly assigned participants (N = 136) to happiness (positive affect), sadness (negative affect), and neutral video-induction conditions prior to engaging in self-paced reading of a long, complex science text. Participants completed assessments targeting multiple levels of comprehension (e.g. recognising factual information, integrating different textual components, and open-ended responses of concepts from memory) after reading and after a week-long delay. Results indicated that the Sadness (vs. Happiness) condition had higher comprehension scores, with the largest effects emerging for assessments targeting deeper levels comprehension immediately after reading. Eye-tracking analyses revealed that such benefits may be partly driven by sustained attentional focus over the 20-minute reading session. We discuss results with respect to theories on affect, cognition, and text comprehension.
Joint description of the e+e- annihilation into both four-pion channels

description: The e+e- --> pi+pi-pi0pi0 reaction cross section as a function of the incident energy is calculated using a model that is an extension of our recently published model of the e+e- annihilation into four charged pions. The latter considered the intermediate states with the pi, rho, and a_1 mesons and fixed the mixing angle of the a_1-rho-pi Lagrangian and other parameters by fitting the cross section data. Here we supplement the original intermediate states with those containing omega(782) and h_1(1170), but keep unchanged the values of those parameters that enter both charged and mixed channel calculations. The inclusion of omega is vital for obtaining a good fit to the cross section data, while the intermediate states with h_1 further improve it. Finally, we merge our models of the e+e- --> pi+pi-pi0pi0 and e+e- --> pi+pi-pi+pi- reactions and obtain a simultaneous good fit.

description: The absolute differential cross sections for small-angle proton elastic scattering off the nuclei $^{12,14-17}$C have been measured in inverse kinematics at energies near 700 MeV/u at GSI Darmstadt. The hydrogen-filled ionization chamber IKAR served simultaneously as a gas target and a detector for the recoil protons. The projectile scattering angles were measured with multi-wire tracking detectors. The radial nuclear matter density distributions and the root-mean-square nuclear matter radii were deduced from the measured cross sections using the Glauber multiple-scattering theory. A possible neutron halo structure in $^{15}$C, $^{16}$C and $^{17}$C is discussed. The obtained data show evidence for a halo structure in the $^{15}$C nucleus.

description: We develop a manifestly microscopic method to deal with strongly interacting nuclear systems that have different interactions in spin-singlet and spin-triplet states. In a first step we analyze variational wave functions that have been suggested to describe such systems, and demonstrate that the so-called commutator contributions can have important effects whenever the interactions in the spin-singlet and the spin-triplet states are very different. We then identify these contributions as terms that correspond, in the language of perturbation theory, to non-parquet diagrams. We include these diagrams in a way that is suggested by the Jastrow-Feenberg approach and show that the corrections from non-parquet contributions are, at short distances, larger than all other many-body effects.

description: We study the assisted inflation scenario from the rolling of $N$ BPS D3-brane into the NS5-branes, on a transverse geometry of $R^3 \times S^1$, coupled to four dimensional gravity. We assume that the branes are distributed along $S^1$ and the probe D3-branes spin along $R^3$ plane. Qualitatively this process is similar to that of N-tachyon assisted inflation on unstable D-branes. We further study the spinflation scenario numerically and analyze its effect.

description: Recently, approach-avoidance tendencies and visual perception biases have been increasingly studied using bistable point-light walkers (PLWs). Prior studies have found a facing-the-viewer bias when one is primed with general threat stimuli (e.g. angry faces), explained by the “error management theory”, as failing to detect a threat as approaching is riskier than the opposite. Importantly, no study has explored how disease threat – linked to the behavioural immune system – might affect this bias. This study aimed to explore whether disease-signalling cues can alter how we perceive the motion direction of ambiguous PLWs. Throughout 3 experiments, participants indicated the motion direction of a bistable PLW previously primed with a control or disease-signalling stimuli – that is, face with a surgical mask (Experiment 1), sickness sound (Experiment 2), or face with a disease cue (Experiment 3). Results showed that sickness cues do not significantly modulate the perception of approach-avoidance behaviours. However, a pattern emerged in Experiments 2 and 3, suggesting that sickness stimuli led to more facing away percepts. Unlike other types of threat, this implies that disease-related threat stimuli might trigger a distinct perceptual bias, indicating a preference to avoid a possible infection source. Nonetheless, this finding warrants future investigations.
Conditional Action and imperfect Erasure of Qubits

description: We consider state changes in quantum theory due to "conditional action" and relate these to the discussion of entropy decrease due to interventions of "intelligent beings" and the principles of Szilard and Landauer/Bennett. The mathematical theory of conditional actions is a special case of the theory of "instruments" which describes changes of state due to general measurements and will therefore be briefly outlined in the present paper. As a detailed example we consider the imperfect erasure of a qubit that can also be viewed as a conditional action and will be realized by the coupling of a spin to another small spin system in its ground state.

description: We report on the possibility of detecting a submillimetre-sized extra dimension by observing gravitational waves (GWs) emitted by pointlike objects orbiting a braneworld black hole. Matter in the `visible' universe can generate a discrete spectrum of high frequency GWs with amplitudes moderately weaker than the predictions of general relativity (GR), while GW signals generated by matter on a `shadow' brane hidden in the bulk are potentially strong enough to be detected using current technology. We know of no other astrophysical phenomena that produces GWs with a similar spectrum, which stresses the need to develop detectors capable of measuring this high-frequency signature of large extra dimensions.

Bi-partite entanglement entropy in integrable models with backscattering

description: In this paper we generalise the main result of a recent work by J. L. Cardy and the present authors concerning the bi-partite entanglement entropy between a connected region and its complement. There the expression of the leading order correction to saturation in the large distance regime was obtained for integrable quantum field theories possessing diagonal scattering matrices. It was observed to depend only on the mass spectrum of the model and not on the specific structure of the diagonal scattering matrix. Here we extend that result to integrable models with backscattering (i.e. with non-diagonal scattering matrices). We use again the replica method, which connects the entanglement entropy to partition functions on Riemann surfaces with two branch points. Our main conclusion is that the mentioned infrared correction takes exactly the same form for theories with and without backscattering. In order to give further support to this result, we provide a detailed analysis in the sine-Gordon model in the coupling regime in which no bound states (breathers) occur. As a consequence, we obtain the leading correction to the sine-Gordon partition function on a Riemann surface in the large distance regime. Observations are made concerning the limit of large number of sheets.

description: Analyzing the magnetic structure factor of a field demagnetized artificial square ice, qualitative deviations from what would predict the square ice model are observed. Combining micromagnetic and Monte Carlo simulations, we demonstrate that these deviations signal the presence of interactions between nanomagnets that extend beyond nearest neighbors. Including further neighbor, dipolar-like couplings in the square ice model, we find that the first seven or eight coupling strengths are needed to reproduce semi-quantitatively the main features of the magnetic structure factor measured experimentally. An alternative, more realistic numerical scenario is also proposed in which the ice condition is slightly detuned. In that case as well, the features evidenced in the experimental magnetic structure factor are only well-described when further neighbor couplings are taken into account. Our results show that long range dipolar interactions are not totally washed out in a field demagnetized artificial square ice, and cannot be neglected as they impact the magnetic correlations within or at the vicinity of the ice manifold.

Epicurean aestheticism: De Quincey, Pater, Wilde, Stoppard
Creators: name: Emilsson, Wilhelm
Publisher: name: University of British Columbia
Year: 2009

description: This is a study of what I argue is a neglected side of Aestheticism. A standard definition of Aestheticism is that its practitioners turn away from the general current of modernity to protest its utilitarian and materialistic values, but this generalization ignores the profound influence of contemporary philosophical and scientific thought on such major figures of British Aestheticism as Walter Pater and Oscar Wilde. This study focuses on Aesthetes who are not in flight from modernity. I call their type of Aestheticism "Epicurean Aestheticism" and argue that since this temperament is characterized by a willingness to engage with the flux of modern times it must be distinguished from the more familiar, escapist form of Aestheticism I call "Platonic Aestheticism." I propose that Aestheticism be viewed as a spectrum with Epicurean Aestheticism on one side and the Platonic variety on the other. While Platonic Aesthetes like W. B . Yeats and Stephane Mallarme continue the Romantic project of trying to counter modernity with various idealist and absolutist philosophies, Epicurean Aesthetes adopt materialist and relativistic strategies in their desire to make the most of modern life. I argue that the first unmistakable signs of Epicurean Aestheticism are to be found in Thomas De Quincey, that the sensibility is fully formulated be Pater, continued by Wilde, and finds a current representative in Tom Stoppard. All Aesthetes are dedicated to the pursuit of beauty, but Platonic Aesthetes seek beauty in an eternal and transcendent realm, while Epicurean Aesthetes have given up such absolutist habits of thought. Pater writes: "Modern thought is distinguished from ancient by its cultivation of the "relative" spirit in place of the "absolute." Epicurean Aesthetes want a new aesthetic that will parallel the paradigm shift from absolutism to relativism. While a nostalgic, quasi-religious longing for a purely ideal realm characterizes Platonic Aesthetes, Epicurean Aesthetes accept that the high, idealistic road to eternal beauty is closed. Instead of lamenting this fact, they start looking for beauty among the uncertainties of the phenomenal world: by viewing life as an aesthetic spectacle to be observed and experimented on with playful detachment they become Epicureans of the flux of modernity.

description: The design, integration, testing, and launch of the first Finnish satellite Aalto-1 is briefly presented in this paper. Aalto-1, a three-unit CubeSat, launched into Sun-synchronous polar orbit at an altitude of approximately 500 km, is operational since June 2017. It carries three experimental payloads: Aalto Spectral Imager (AaSI), Radiation Monitor (RADMON), and Electrostatic Plasma Brake (EPB). AaSI is a hyperspectral imager in visible and near-infrared (NIR) wavelength bands, RADMON is an energetic particle detector and EPB is a de-orbiting technology demonstration payload. The platform was designed to accommodate multiple payloads while ensuring sufficient data, power, radio, mechanical and electrical interfaces. The design strategy of platform and payload subsystems consists of in-house development and commercial subsystems. The CubeSat Assembly, Integration & Test (AIT) followed Flatsat -- Engineering-Qualification Model (EQM) -- Flight Model (FM) model philosophy for qualification and acceptance. The paper briefly describes the design approach of platform and payload subsystems, their integration and test campaigns, and spacecraft launch. The paper also describes the ground segment & services that were developed by the Aalto-1 team.

description: Several authors assume that evaluative conditioning (EC) relies on high-level propositional thinking. In contrast, the dual-process perspective proposes two processing pathways, one associative and the other propositional, contributing to EC. Dual-process theorists argue that attitudinal ambiguity resulting from these two pathways’ conflicting evaluations demonstrate the involvement of both automatic and controlled processes in EC. Previously, we suggested that amplitude variations of error-related negativity and error-positivity, two well-researched event-related potentials of performance monitoring, allow for the detection of attitudinal ambiguity at the neural level. The present study utilises self-reported evaluation, categorisation performance, and neural correlates of performance monitoring to explore associative-propositional ambiguity during social attitude formation. Our results show that compared to associative-propositional harmony, attitudinal ambiguity correlates with more neutral subjective evaluations, longer response times, increased error commission, and diminished error-related negativity amplitudes. While our findings align with dual-process models, we aim to offer a propositional interpretation. We discuss dual-process theories in the context of evolutionary psychology, suggesting that associative processes may only represent a small piece of the EC puzzle.

description: We investigate the issue of "dangerous human-made interference with climate" using simulations with GISS modelE driven by measured or estimated forcings for 1880-2003 and extended to 2100 for IPCC greenhouse gas scenarios as well as the 'alternative' scenario of Hansen and Sato. Identification of 'dangerous' effects is partly subjective, but we find evidence that added global warming of more than 1 degree C above the level in 2000 has effects that may be highly disruptive. The alternative scenario, with peak added forcing ~1.5 W/m2 in 2100, keeps further global warming under 1 degree C if climate sensitivity is \~3 degrees C or less for doubled CO2. We discuss three specific sub-global topics: Arctic climate change, tropical storm intensification, and ice sheet stability. Growth of non-CO2 forcings has slowed in recent years, but CO2 emissions are now surging well above the alternative scenario. Prompt actions to slow CO2 emissions and decrease non-CO2 forcings are needed to achieve the low forcing of the alternative scenario.

description: Positive emotions (PEs) impact cognitive processes, including executive functions (EFs; i.e. inhibition, working memory, cognitive flexibility). However, previous reviews and meta-analyses report contradicting results. Thus, this review takes a novel approach to overcome conflicting findings by clearly conceptualising PE induction and by providing a detailed description of the tasks used to assess EFs, as well as by exclusively focusing on EFs. A systematic literature review and meta-analysis was performed. Study inclusion criteria required that subjects were healthy individuals over 18 years, PEs were induced in a controlled laboratory setting, a baseline measurement and a control condition was required, and finally, EFs were measured as a dependent variable using valid measurement instruments. The literature search was performed on PRIMUS, including relevant databases such as ERIC, MEDLINE, Psych ARTICLES, Psych INFO or SocINDEX. From a total of 6,661 identified articles, only 13, which featured 20 experimental studies, were included. Results show that the overall induction of PEs successfully caused an increase in valence and/or positive emotions. However, no significant effects of PE on EFs were detected (d  =  −0.051, p  =  .405). Reasons and future research will be discussed.

description: We present results from an optical spectroscopic investigation of the massive binary system [L72] LH~54-425 in the LH 54 OB association in the Large Magellanic Cloud. We revise the ephemeris of [L72] LH 54-425 and find an orbital period of 2.247409 +/- 0.000010 days. We find spectral types of O3 V for the primary and O5 V for the secondary. We made a combined solution of the radial velocities and previously published V-band photometry to determine the inclination for two system configurations, i = 52 degrees for the configuration of the secondary star being more tidally distorted and i = 55 degrees for the primary as the more tidally distorted star. We argue that the latter case is more probable, and this solution yields masses and radii of M_1 = 47 +/- 2 M_Sun and R_1 = 11.4 +/- 0.1 R_Sun for the primary, and M_2 = 28 +/- 1 M_Sun and R_2 = 8.1 +/- 0.1 R_Sun for the secondary. Our analysis places LH 54-425 amongst the most massive stars known. Based on the position of the two stars plotted on a theoretical HR diagram, we find the age of the system to be about 1.5 Myr.

description: Clostophis koilobasis Páll-Gergely & Vermeulen, new species (Fig. 6) Type material. Holotype (SH: 1.06 mm, SW: 1.22 mm) (NHMUK 20191126; original inv. number: JJV 6230), Vietnam, Haiphong Prov., Cat Ba Isl., NE coast, 20°49.25′N 107°03.45′E, dry limestone scree slope with low woodland, in rock crevices, leg. J.J. Vermeulen & A.J. Whitten, 01 October 1998. Diagnosis. A low conical shell with strongly widened body whorl, very wide umbilicus, and an elevated, distorted, short parietal lamella. Description. Shell low triangular, wider than tall, with concave sides and strongly widened last whorl. Body whorl rounded, aperture not detached. Protoconch consisting of 1.25 whorls, with very finely raised threads arranged into hardly visible, widely-spaced spiral striae. Entire shell consisting of 4.75 whorls. Teleoconch with irregular, fine growth lines and dense (body whorl) and widely-spaced (previous whorls) spiral striation. Spiral striae ca. 22 on body whorl from lateral view (the holotype was strongly corroded, therefore the spiral striae were not counted from apertural view). Umbilicus very wide, occupies almost half of the shell width. Aperture subovate, peristome very slightly expanded, not reflected. Parietal tooth elevated, strong, but short, distorted internally (oblique to the growth axis of the body whorl). Etymology. Combination of 'koilos' (= hollow in Greek) and 'basis' (= base in Greek), referring to the wide umbilicus as well as to the concave spire. Differential diagnosis. Clostophis incurvus, new species, which is also known from the Halong Bay area, has a taller shell with narrower umbilicus and a strong parietal tooth. Clostophis platytrochus, new species, is somewhat similar in shell shape, but has a slightly keeled body whorl, a detached terminal part of the peristome, a strongly oblique aperture, and a strong palatal tooth. Some populations of Clostophis multiformis, new species, are similar to C. koilobasis, new species, in shell shape, but that species always has a low parietal tooth and narrower umbilicus.

description: We present an implementation of Grover's algorithm in the framework of Feynman's cursor model of a quantum computer. The cursor degrees of freedom act as a quantum clocking mechanism, and allow Grover's algorithm to be performed using a single, time-independent Hamiltonian. We examine issues of locality and resource usage in implementing such a Hamiltonian. In the familiar language of Heisenberg spin-spin coupling, the clocking mechanism appears as an excitation of a basically linear chain of spins, with occasional controlled jumps that allow for motion on a planar graph: in this sense our model implements the idea of "timing" a quantum algorithm using a continuous-time random walk. In this context we examine some consequences of the entanglement between the states of the input/output register and the states of the quantum clock.

description: We calculate the accurate spectrum of the stochastic gravitational wave background from U(1) gauge fields produced by axion dark matter. The explosive production of gauge fields soon invalidates the applicability of the linear analysis and one needs nonlinear schemes. We make use of numerical lattice simulations to properly follow the nonlinear dynamics such as backreaction and rescattering which gives important contributions to the emission of gravitational waves. It turns out that the axion with the decay constant $f \sim 10^{16}$ GeV which gives the correct dark matter abundance predicts the circularly polarized gravitational wave signature detectable by SKA. We also show that the resulting gravitational wave spectrum has a potential to explain NANOGrav 12.5 year data.

A Sample of Quasars with Strong Nitrogen Emission Lines from the Sloan Digital Sky Survey

description: We report on 293 quasars with strong NIV] lambda 1486 or NIII] lambda 1750 emission lines (rest-frame equivalent width > 3 Å) at 1.7 < z < 4.0 selected from the Sloan Digital Sky Survey (SDSS) Fifth Data Release. These nitrogen-rich (N-rich) objects comprise ~1.1% of the SDSS quasars. The comparison between the N-rich quasars and other quasars shows that the two quasar subsets share many common properties. We also confirm previous results that N-rich quasars have much stronger Lya and NV lambda 1240 emission lines. Strong nitrogen emission in all ionization states indicates high overall nitrogen abundances in these objects. We find evidence that the nitrogen abundance is closely related to quasar radio properties. The radio-loud fraction in the NIII]-rich quasars is 26% and in the NIV]-rich quasars is 69%, significantly higher than ~8% measured in other quasars with similar redshift and luminosity. Therefore, the high nitrogen abundance in N-rich quasars could be an indicator of a special quasar evolution stage, in which the radio activity is also strong.

description: Clostophis obtusus Páll-Gergely & Grego, new species (Fig. 10) Material examined. Holotype (SH: 1.39 mm, SW: 1.22 mm) (HNHM 104435), Laos, Khammouane Province, Tham Nam Dôn Cave, Earthquake Dome, sand sediments at bank of cave river, 160 m a.s.l., 17°33.815′N, 104°52.298′E (locality code: JG2B), coll. J. Grego, 11 February 2017. Paratypes: 2 shells (coll. JG), same data as preceding; 1 shell (coll. JG), Laos, Khammouane Prov., 2 km WNW of Ban Na village, Pha Soung Cave – Frog lake, 17°33.054′N, 104°52.414′E (locality code: JG3A), leg. J. Grego, 09 February 2017. Diagnosis. A relatively large, triangular Clostophis species with blunt apex, a relatively narrow umbilicus, and a parietal tooth that is only slightly indicated. Description. Shell conical, higher than wide. Whorls rounded and very slightly shouldered. Tuba not detached from penultimate whorl. Protoconch nearly reaches 1.75 whorls, pitted and spirally striated. Entire shell with 4.5 whorls. Umbilicus narrow. Entire teleoconch with rather equidistant spiral striae, and some weak, irregular radial growth lines. Aperture subcircular with straight parietal part. Parietal tooth very weak, only slightly indicted, but as long as in C. multiformis, new species. Aperture not adnate to penultimate whorl. Peristome expanded but not reflected. Measurements (in mm). SH = 1.17–1.39, SW = 1.07–1.24 (n = 4). Etymology. The specific epithet " obtusus " (= obtuse, blunt in Latin) refers to the blunt apex of this new species. Differential diagnosis. Clostophis obtusus, new species, differs from C. multiformis, new species (populations northeast of Thakhek), in the following traits: the shell of C. obtusus is larger, always triangular, not ovoid, apex blunter, umbilicus narrower, aperture never detached from penultimate whorl, parietal tooth weaker. Remarks. We first considered this species to be fitting into the wide variability of C. multiformis, new species, but in fact, at one site (locality: JG2B) the two species occur sympatrically.

description: This review describes the physics of spins in quantum dots containing one or two electrons, from an experimentalist's viewpoint. Various methods for extracting spin properties from experiment are presented, restricted exclusively to electrical measurements. Furthermore, experimental techniques are discussed that allow for: (1) the rotation of an electron spin into a superposition of up and down, (2) the measurement of the quantum state of an individual spin and (3) the control of the interaction between two neighbouring spins by the Heisenberg exchange interaction. Finally, the physics of the relevant relaxation and dephasing mechanisms is reviewed and experimental results are compared with theories for spin-orbit and hyperfine interactions. All these subjects are directly relevant for the fields of quantum information processing and spintronics with single spins (i.e. single-spintronics).

Generalized Bloch analysis and propagators on Riemannian manifolds with a discrete symmetry

description: We consider an invariant quantum Hamiltonian $H=-Δ_{LB}+V$ in the $L^{2}$ space based on a Riemannian manifold $\tilde{M}$ with a countable discrete symmetry group $Γ$. Typically, $\tilde{M}$ is the universal covering space of a multiply connected Riemannian manifold $M$ and $Γ$ is the fundamental group of $M$. On the one hand, following the basic step of the Bloch analysis, one decomposes the $L^{2}$ space over $\tilde{M}$ into a direct integral of Hilbert spaces formed by equivariant functions on $\tilde{M}$. The Hamiltonian $H$ decomposes correspondingly, with each component $H_Λ$ being defined by a quasi-periodic boundary condition. The quasi-periodic boundary conditions are in turn determined by irreducible unitary representations $Λ$ of $Γ$. On the other hand, fixing a quasi-periodic boundary condition (i.e., a unitary representation $Λ$ of $Γ$) one can express the corresponding propagator in terms of the propagator associated to the Hamiltonian $H$. We discuss these procedures in detail and show that in a sense they are mutually inverse.
Differential calculus for Dirichlet forms : the measure-valued gradient preserved by image

description: In order to develop a differential calculus for error propagation we study local Dirichlet forms on probability spaces with square field operator $Γ$ -- i.e. error structures -- and we are looking for an object related to $Γ$ which is linear and with a good behaviour by images. For this we introduce a new notion called the measure valued gradient which is a randomized square root of $Γ$. The exposition begins with inspecting some natural notions candidate to solve the problem before proposing the measure-valued gradient and proving its satisfactory properties.
Isoreticular Expansion and Linker Enabled Control of Interpene-tration in Titanium-Organic Frameworks

description: Titanium-organic frameworks offer distinctive opportunities in the realm of Metal-Organic Frameworks (MOFs) due to the integration of intrinsic photoactivity or redox versatility in porous architectures with ultrahigh stability. Unfortunately, the high polarizing power of Ti+4 cations make them prone to hydrolysis, thus preventing the systematic design of this type of frameworks. We illustrate the use of the heterobimetallic cluster Ti2Ca2 as a persistent building unit compatible with the isoreticular design of titanium frameworks. The MUV-12(X) and MUV-12(Y) series can be all synthesized as single crystals by using linkers of varying functionalization and size for the formation of the nets with tailorable porosity and degree of interpenetration. Following with the generalization of this approach, we also gain rational control over interpenetration in these nets by designing linkers with varying degrees of steric hindrance to eliminate stacking interactions and access the highest gravimetric surface area reported for titanium(IV) MOFs (3000 m2·g-1).

description: The recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn$_3$$X$, ($X$ = Sn, Ge) have brought the study of magnetic topological states to the forefront of condensed matter research and technological innovation. These effects are considered fingerprints of Weyl nodes residing near the Fermi energy, promoting Mn$_3$$X$, ($X$ = Sn, Ge) as a fascinating platform to explore the elusive magnetic Weyl fermions. In this review, we provide recent updates on the insights drawn from experimental and theoretical studies of Mn$_3$$X$, ($X$ = Sn, Ge) by combining previous reports with our new, comprehensive set of transport measurements of high-quality Mn$_3$Sn and Mn$_3$Ge single crystals. In particular, we report magnetotransport signatures specific to chiral anomalies in Mn$_3$Ge and planar Hall effect in Mn$_3$Sn, which have not yet been found in earlier studies. The results summarized here indicate the essential role of magnetic Weyl fermions in producing the large transverse responses in the absence of magnetization.
