description: The ligand, 4-chloro-2,6-dipicolinic acid (H2PDA-Cl), and its two heavy metal complexes, [Ag(HDPA-Cl)(H2DPA-Cl)·2H2O] (1) and {[Cd(μ2-H2O)(H2O)(PDA-Cl)]}n (2), were prepared and then characterized by single-crystal X-ray diffraction. In addition, spectral and thermal correlations with structural results complete their solid-state description and facilitate complex 3 ([Pb(DPA-Cl)]) composition determinations. Complex 1 crystallizes in a monoclinic space group C2/c and each DPA-Cl ligand is tridentate to Ag(I) through the pyridine N and two monodentate carboxyl O atoms. The carboxy group with carbonyl C1 is semideprotonated and forms a symmetric hydrogen bond with a carboxy group of a neighboring complex. Complex 2 crystallizes in a triclinic lattice with space group P. The Cd(II) ions are seven-coordinate and the coordination polyhedra can be described as a distorted pentagonal bipyramid. IR data are consistent with monodentate coordination of the carboxylate to Ag(I), Cd(II), and Pb(II) and observed wavenumber shifts confirm PDA-Cl ligand coordination to Pb(II) in 3. Thermal stability of anhydrous complexes indicates the metal–ligand interactions. The thermal stability of prepared compounds is reflected by the strength of interaction between metal–ligand and hydrogen bonds.

description: Abstract: The weighted Phase Lag Index (wPLI) and the weighted Symbolic Mutual Information (wSMI) represent two robust and widely used methods for MEG/EEG functional connectivity estimation. Interestingly, both methods have been shown to detect relative alterations of brain functional connectivity in conditions associated with changes in the level of consciousness, such as following severe brain injury or under anaesthesia. Despite these promising findings, it was unclear whether wPLI and wSMI may account for distinct or similar types of functional interactions. Using simulated high-density (hd-)EEG data, we demonstrate that, while wPLI has high sensitivity for couplings presenting a mixture of linear and nonlinear interdependencies, only wSMI can detect purely nonlinear interaction dynamics. Moreover, we evaluated the potential impact of these differences on real experimental data by computing wPLI and wSMI connectivity in hd-EEG recordings of 12 healthy adults during wakefulness and deep (N3-)sleep, characterised by different levels of consciousness. In line with the simulation-based findings, this analysis revealed that both methods have different sensitivity for changes in brain connectivity across the two vigilance states. Our results indicate that the conjoint use of wPLI and wSMI may represent a powerful tool to study the functional bases of consciousness in physiological and pathological conditions.

description: The retention behavior, lipophilicity of 16,17-secoestrone derivatives and efficiency in the separation of halogenated derivatives by HPLC with pentafluorophenyl-propyl stationary phase (F5) were studied. Methanol-water (MeOH-W) and acetonitrile-water (ACN-W) were used as mobile phases in proportions according to nomograph of iso-eluotropic binary solvent mixtures. Since mobile phase ACN-W was more effective eluent, the retention behavior of 16,17-secoesterone derivatives has further been evaluated, with water content increasing in increments of 5%. The retention constants log k for mobile phases MeOH-W and ACN-W, have been compared by applying Student’s paired t-test and Fisher’s F-test to determine the applicability of the nomograph to this column. Linear correlations were obtained between parameters log k0 and log P, as well as φ0 and log P, for both MeOH-W and ACN-W eluents. Compared with log k0, the hydrophobicity index φ0 proved to be better parameter for lipophylicity estimation of these compounds. According to the separation efficacy of individual components, as well as mixtures of halogenated secoestone compounds, chromatographic columns can be placed in the following order: C18> F5> C8. This result is of huge importance for the field of synthesis, purification and characterization of novel biologically and pharmacologically active compounds and steroids among them.

description: We establish the presence of foliated fracton order in the Majorana checkerboard model. In particular, we describe an entanglement renormalization group transformation which utilizes toric code layers as resources of entanglement, and furthermore discuss entanglement signatures and fractional excitations of the model. In fact, we give an exact local unitary equivalence between the Majorana checkerboard model and the semionic X-cube model augmented with decoupled fermionic modes. This mapping demonstrates that the model lies within the X-cube foliated fracton phase.

0259 Reconsidering Anders Zorn’s Omnibus Paintings
Creators: name: Jansson, Emma
Publisher: name: RIHA Journal
Year: 2022

description: This article reconsiders the relationship between Anders Zorn’s (1860–1920) Omnibus paintings. Two largescale versions exist for the Omnibus motif (Omnibus I and Omnibus II), both of which have historically been viewed as official works that were exhibited by Zorn during the years 1892–1893. Drawing upon recent technical analyses of the artist’s oil paintings, together with relevant archival sources, a discussion is put forward with the aim of reconfiguring the earlier Omnibus I (1891) version as an initial sketch (esquisse) to the later Omnibus II (1892).

description: Abstract: Epitaxial films may be released from growth substrates and transferred to structurally and chemically incompatible substrates, but epitaxial films of transition metal perovskite oxides have not been transferred to electroactive substrates for voltage control of their myriad functional properties. Here we demonstrate good strain transmission at the incoherent interface between a strain-released film of epitaxially grown ferromagnetic La0.7Sr0.3MnO3 and an electroactive substrate of ferroelectric 0.68Pb(Mg1/3Nb2/3)O3-0.32PbTiO3 in a different crystallographic orientation. Our strain-mediated magnetoelectric coupling compares well with respect to epitaxial heterostructures, where the epitaxy responsible for strong coupling can degrade film magnetization via strain and dislocations. Moreover, the electrical switching of magnetic anisotropy is repeatable and non-volatile. High-resolution magnetic vector maps reveal that micromagnetic behaviour is governed by electrically controlled strain and cracks in the film. Our demonstration should inspire others to control the physical/chemical properties in strain-released epitaxial oxide films by using electroactive substrates to impart strain via non-epitaxial interfaces.

Fourth generation effects on the rare $B\to K^{*}ν\barν$ decay

Year: 2001
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: If the fourth generation fermions exist, the new quarks could influence the branching ratio of the rare $B\to K^{*}ν\barν$ decay. Two possible solutions of the fourth generation CKM factor $(V^{*}_{\acute{t}s}V_{\acute{t}b})^(\pm)$ are obtained as a function of the new $\acute{t}$-quark mass $(m_{\acute{t}})$ from the experimental results of the $B\to X_{s}γ$ together with the semileptonic decay $B\to X_{c}\ell\barν$. The branching ratio of the decay $B\to K^{*}ν\barν$ in the two cases is estimated. In one case, a significant enhancement to the branching ratio of the decay $B\to K^{*}ν\barν$ over the SM is recorded, while results are almost same in another case. If a fourth generation should exist in nature and nature chooses the former case, this B meson decay could be a good probe to the existence of the fourth generation, or perhaps a signal for a new physics.

description: We discuss periodic compactification and latticization of a 5-D U(1) theory with a Dirac fermion, yielding a 1+3 effective theory. We address subtleties in the lattice fermionic action,such as fermion doubling and the Wilson term. We compute the Coleman-Weinberg potential for the Wilson line which is finite for N-branes >= 3, due to the Z_N symmetry, which replaces translations in the 5th dimension. This mode becomes a PNGB in the low energy 1+3 theory. We derive its anomalous coupling to the "photon" and its KK-modes.

description: The pseudofermion functional renormalization group (pf-FRG) has been put forward as a semi-analytical scheme that, for a given microscopic spin model, allows to discriminate whether the low-temperature states exhibit magnetic ordering or a tendency towards the formation of quantum spin liquids. However, the precise nature of the putative spin liquid ground state has remained hard to infer from the original (single-site) pf-FRG scheme. Here we introduce a cluster pf-FRG approach, which allows for a more stringent connection between a microscopic spin model and its low-temperature spin liquid ground states. In particular, it allows to calculate spatially structured fermion bilinear expectation values on spatial clusters, which are formed by splitting the original lattice into several sublattices, thereby allowing for the positive identification of a family of bilinear spin liquid states. As an application of this cluster pf-FRG approach, we consider the $J_1$-$J_2$ SU($N$)-Heisenberg model on a square lattice, which is a paradigmatic example for a frustrated quantum magnet exhibiting quantum spin liquid behavior for intermediate coupling strengths. In the well-established large-$N$ limit of this model, we show that our approach correctly captures the emergence of the $π$-flux spin liquid state at low temperatures. For small $N$, where the precise nature of the ground state remains controversial, we focus on the widely studied case of $N=2$, for which we determine the low-temperature phase diagram near the strongly-frustrated regime after implementing the fermion number constraint by the flowing Popov-Fedotov method. Our results suggest that the $J_1$-$J_2$-Heisenberg model does not support the formation of a fermion bilinear spin liquid state.

description: Current development in programmable analogue quantum simulators (AQS), whose physical implementation can be realised in the near-term compared to those of large-scale digital quantum computers, highlights the need for robust testing techniques in analogue platforms. Methods to properly certify or benchmark AQS should be efficiently scalable, and also provide a way to deal with errors from state preparation and measurement (SPAM). Up to now, attempts to address this combination of requirements have generally relied on model-specific properties. We put forward a new approach, applying a well-known digital noise characterisation technique called randomized benchmarking (RB) to the analogue setting. RB is a scalable experimental technique that provides a measure of the average error-rate of a gate-set on a quantum hardware, incorporating SPAM errors. We present the original form of digital RB, the necessary alterations to translate it to the analogue setting and introduce the analogue randomized benchmarking protocol (ARB). In ARB we measure the average error-rate per time evolution of a family of Hamiltonians and we illustrate this protocol with two case-studies of analogue models; classically simulating the system by incorporating several physically motivated noise scenarios. We find that for the noise models tested, the data fit with the theoretical predictions and we gain values for the average error rate for differing unitary sets. We compare our protocol with other relevant RB methods, where both advantages (physically motivated unitaries) and disadvantages (difficulty in reversing the time-evolution) are discussed.

description: We studied how rehabilitation of forests in Indonesia by planting teak, Tectona grandis (L.f.), and mahogany, Swietenia macrophylla (King), was associated with soil pH, organic matter, total nitrogen, total phosphorus, and total potassium. We also analyzed how soil properties and the environment (i.e. soil order, altitude, stand age) were associated with succession and compared rehabilitated stands with native forests. We found higher pH in teak compared to mahogany stands. The soil pH was lowest in the oldest stands (>70 years). Herb density was positively related to pH and to phosphorus, while density of seedlings and woody plants was positively related to nitrogen, potassium and phosphorus. Tree and herb species richness and tree density were positively associated with Oxisols, but negatively related to the proportion of native herbs. Species richness of herbs and density of seedlings decreased with time since rehabilitation, whereas species richness of woody plants increased. The proportion of native herbs and seedlings increased with stand age. We found few differences in soils between the planted stands and native forest. Our results demonstrated that successional vegetation of rehabilitated forests may play an important role in maintaining soil properties associated with soil order.

description: Abstract: The spread of online misinformation poses serious challenges to societies worldwide. In a novel attempt to address this issue, we designed a psychological intervention in the form of an online browser game. In the game, players take on the role of a fake news producer and learn to master six documented techniques commonly used in the production of misinformation: polarisation, invoking emotions, spreading conspiracy theories, trolling people online, deflecting blame, and impersonating fake accounts. The game draws on an inoculation metaphor, where preemptively exposing, warning, and familiarising people with the strategies used in the production of fake news helps confer cognitive immunity when exposed to real misinformation. We conducted a large-scale evaluation of the game with N = 15,000 participants in a pre-post gameplay design. We provide initial evidence that people’s ability to spot and resist misinformation improves after gameplay, irrespective of education, age, political ideology, and cognitive style.

Adding arms
Concurrent/ non-concurrent control
Platform trials

description: Abstract: Background: Platform trials allow adding new experimental treatments to an on-going trial. This feature is attractive to practitioners due to improved efficiency. Nevertheless, the operating characteristics of a trial that adds arms have not been well-studied. One controversy is whether just the concurrent control data (i.e. of patients who are recruited after a new arm is added) should be used in the analysis of the newly added treatment(s), or all control data (i.e. non-concurrent and concurrent). Methods: We investigate the benefits and drawbacks of using non-concurrent control data within a two-stage setting. We perform simulation studies to explore the impact of a linear and a step trend on the inference of the trial. We compare several analysis approaches when one includes all the control data or only concurrent control data in the analysis of the newly added treatment. Results: When there is a positive trend and all the control data are used, the marginal power of rejecting the corresponding hypothesis and the type one error rate can be higher than the nominal value. A model-based approach adjusting for a stage effect is equivalent to using concurrent control data; an adjustment with a linear term may not guarantee valid inference when there is a non-linear trend. Conclusions: If strict error rate control is required then non-concurrent control data should not be used; otherwise it may be beneficial if the trend is sufficiently small. On the other hand, the root mean squared error of the estimated treatment effect can be improved through using non-concurrent control data.

description: The Physical Education and Nutrition Education Working Together (PE-Nut) program was evaluated to determine the impact nutrition and physical education has on students’ academic performance. Administrative data was collected from 8 Traverse City Michigan Area Public Schools (TCAPS), four schools that administered PE-Nut (treatment) and four schools that did not administer PE-Nut (control). Regression analysis was utilized to identify the treatment effect of PE-Nut on students’ academic performance. Overweight and obese students that participated in PE-Nut were 12% and 9% more likely to be proficient in reading. For math and writing, overweight and obese students that participated in PE-Nut were 22% and 13% more likely to be proficient at math, and 14% and 13% more likely to be proficient in writing. Implications from these results are nutrition and physical education programs can have a positive spillover effect on students’ academic performance. The estimated economic impact of students participating in PE-Nut suggests that participants can improve their future wages by nearly $10,000.

This (transient) region, where the electron swarm exhibits non-equilibrium character with energy gain and loss processes taking place at separate positions (in space and time), is monitored experimentally in a scanning drift tube apparatus. Depending on the strength of the reduced electric field we observe the equilibration of the swarm over different length scales, beyond which the energy gain and loss mechanism becomes locally balanced and transport properties become spatially invariant. The evolution of the electron swarm in the experimental apparatus is also described by Monte Carlo simulations, of which the results are in good agreement with the experimental observations, over the domains of the reduced electric field and the gas pressure covered.

description: One electron system minimally coupled to a quantized radiation field is considered. It is assumed that the quantized radiation field is {\it massless}, and {\it no} infrared cutoff is imposed. The Hamiltonian, $H$, of this system is defined as a self-adjoint operator acting on $\LR\otimes\fff\cong L^2(\BR;\fff)$, where $\fff$ is the Boson Fock space over $L^2(\BR\times\{1,2\})$. It is shown that the ground state, $\gr$, of $H$ belongs to $\cap_{k=1}^\infty D(1\otimes N^k)$, where $N$ denotes the number operator of $\fff$. Moreover it is shown that, for almost every electron position variable $x\in\BR$ and for arbitrary $k\geq 0$, $\|(1\otimes \N)\gr (x) \|_\fff \leq D_ke^{-δ|x|^{m+1}}$ with some constants $m\geq 0$, $D_k>0$, and $δ>0$ independent of $k$. In particular $\gr\in \cap_{k=1}^\infty D (e^{β|x|^{m+1}}\otimes N^k)$ for $0

description: The Supplemental Nutrition Assistance Program (SNAP) is the largest nutrition assistance program in the United States and is a vital part of the social safety net. The monthly lump-sum benefit distribution schedule has led to higher food expenditures and consumption shortly after the date of benefit receipt, and a diminishing food expenditures and associated food consumption pattern towards the end of the benefit month. This has been found to have adverse effects on beneficiaries' dietary outcomes. In this paper, we investigate food purchasing patterns of SNAP households over the month using data from the National Food Acquisition and Purchase Survey (FoodAPS), a newly developed nationally representative survey, and its geographic component. We ask the research question: do SNAP recipients pay more for otherwise similar food at the beginning of the benefit cycle, and substitute less costly food as the month proceeds? We found that the unit cost of food bought declines significantly over the benefit cycle when households make purchases using SNAP benefits. Our results shed light on the optimal policy design of food assistance programs through a better understanding of program participants' food-purchasing behavior.

description: Kinematical relativistic effects are analyzed within the plane-wave impulse approximation for outgoing nucleon polarized responses in coincidence electron scattering. Following recent approaches for non-relativistic reductions of the electromagnetic current operator, here an exact treatment of the problem for the transferred energy and momentum is presented. Rather than employing existing non-relativistic expressions for the single-nucleon matrix elements, in this work the response functions are expanded directly. Results are compared for different kinematical situations with the fully-relativistic PWIA calculation as well as with previous non-relativistic expansions. Off- and `on-shell' prescriptions are also studied in detail, and a systematic analysis of the various kinematical variables involved in the process is presented.

description: The Upper Washita River basin in southwestern Oklahoma has been the subject of extensive research since the 1930s and is also a participating watershed in the long-term USDA Conservation Effects Assessment Project (CEAP) effort. Much of the research has focused on developing and testing computer models and tools to simulate the impacts of agricultural management practices on soil and water resources. While a substantial portion of these research efforts have focused on the environmental impacts of management practices, economic considerations are now receiving greater attention since funding agencies are better appreciating the link between farm economics and producer adoption of the conservation practices. This paper contributes to a better understanding of how resource conservation benefits of limited available funds can be maximized by optimal distribution of the practices based on publicly available spatial distributions of the biophysical attributes of agricultural lands. We specifically determine optimal conservation practice distributions for two sub-basins of the Upper Washita River basin: the Fort Cobb Reservoir Experimental Watershed (FCREW) and the Little Washita River Experimental Watershed (LWREW).

description: In this paper we use an elementary approach by using numerical semigroups (specifically, those with two generators) to give a formula for the number of integral points inside a right-angled triangle with rational vertices. This is the basic case for computing the number of integral points inside a rational (not necessarily convex) polygon.

description: Although brain tumours kill more people under the age of 40 than any other cancer, and glioblastoma (GBM) is the most common malignant brain tumour, effective brain cancer treatments are not available. The Cancer Stem Cell theory dictates that a subset of cells within a tumour have self-renewal potential and are responsible for tumour formation. GBM stem cells (GSCs) are resistant to conventional therapy and can reform GBM tumours. The Drosophila brain tumour (brat) model is widely used in the study of brain tumourigenesis. Brat determines the fate of intermediate neural progenitors (INPs) in Drosophila brains, acting as a tumour suppressor. Its inhibition causes INP transformation into tumour initiating cells and malignant tumour overgrowth. The human brat orthologue TRIM3 is also described as a tumour suppressor in GBM. A single cell transcriptome analysis by the Barros laboratory identified Yeast Mitochondrial Escape 1-Like (YME1L) upregulated in brat brain tumour initiating cells (Barros laboratory, unpublished). YME1L is a metalloprotease involved in mitochondrial dynamics and respiration, and was recently implicated in proliferation and stemness of mouse neural stem progenitor cells. However, it has not been associated with brain tumours to date. This PhD project aimed to demonstrate YME1L’s potential role in brain tumourigenesis. The findings I describe demonstrate that, in Drosophila and GSCs, YME1L is essential for tumour cell stemness, proliferation and survival. Upon YME1L inhibition, brat-deficient tumour initiating cells differentiate and lose tumourigenic potential. Mitochondrial membrane potential, an indicator of oxidative metabolism, also decreases upon YME1L inhibition in GSCs. Inhibiting YME1L fragments the mitochondrial network in both Drosophila and GSCs. Strikingly, rescue of this effect in GSCs via overexpression of the fusion protein Mitofusin 2 restores their proliferative capacity. Based on these data, a model is proposed in which YME1L-dependent mitochondrial dynamics promotes brain tumour initiation and growth. YME1L is identified as a novel contributor to brain tumourigenesis and may be a potential therapeutic target in future treatments of GBM.

Comets–interstellar
Molecules–interstellar
Grains–panspermia

description: Abstract: A series of astronomical observations obtained over the period 1986 to 2018 supports the idea that life is a cosmic rather than a purely terrestrial or planetary phenomenon. These include (1) the detection of biologically relevant molecules in interstellar clouds and in comets, (2) mid-infrared spectra of interstellar grains and the dust from comets, (3) a diverse set of data from comets including the Rosetta mission showing consistency with biology and (4) the frequency of Earth-like or habitable planets in the Galaxy. We argue that the conjunction of all the available data suggests the operation of cometary biology and interstellar panspermia rather than the much weaker hypothesis of comets being only the source of the chemical building blocks of life. We conclude with specific predictions on the properties expected of extra-terrestrial life if it is discovered on Enceladus, Europa or beyond. A radically different biochemistry elsewhere can be considered as a falsification of the theory of interstellar panspermia.

description: This study analyzes the consumer behavior of three groups: non-participants, potential consumer and current buyer by using a two-stage sample-selection model incorporating a binary probit model and an ordered probit model. Different from the previous research which A consumer survey about fresh mushroom consumption in the U.S was conducted which allows us to observe consumers’ participation intention and acquisition through a purchase history and purchase frequency. The results indicate that there are different reasons driving non-participants (consumers who will not participate in the market) and potential consumers (consumers with zero purchase frequency), and the potential consumers share many similarities with less frequent consumers instead of with non-participants, with whom they are often combined in previous research.

description: This paper analyses strategic permanent grassland conversion decisions in the Dakotas. We present a binary discrete choice model with dynamic decision-making among heterogeneous farmers to evaluate these land use changes. We also explore the role of conservation easements- a policy tool to inhibit grassland conversions. We utilize a spatially-explicit panel dataset to empirically analyze permanent grass conversions relative to the neighborhood characteristics in North Dakota during 1997-2015. A duration modelling approach is used to estimate the risk of conversion for a representative land parcel as a function of the density of grasslands in its locality, and its proximity to previously allocated easements. We find that the land parcels with higher local grass-density ‘survived’ relatively longer before being permanently converted to cropland. This affirms our conjecture that strategic complementarities exist. We further find that easements are a viable conservation tool as their presence in a parcel’s proximity complements higher grass-density and inhibits conversion. However, most easements seem to have been misallocated in the sense that they are generally located away from conversion sites, in proximity of the areas where conversions did not occur anyway.

We establish an analog of the Brauer-Schur-Weyl duality where the action of the new algebra commutes with the representation of the twisted deformation U'_q(o_n) of the enveloping algebra U(o_n) in the tensor power of the vector representation.

description: This paper reviewed global waste management and trade partnership. Major highlights include population effect on waste generation and waste valuation effect on the global south. The global waste partnership proposed by this report has the potential to promote greenhouse gas reduction, create millions of green jobs internationally and offer economic benefits in billions of dollars. By reviewing the global waste trade partnership, we would be moving toward realizing the Sustainable Development Goals and tackling environmental justice. The report does not support a ban on waste export/import between the globe (North and South) but encouraged a paradigm shift about waste as merely a trash and environmental nuisance, towards an economic concept of resource, a non-renewable resource that can be recycled.
