description: We study force generation by a set of parallel actin filaments growing against a non-rigid obstacle, in presence of an external load. The filaments polymerize by either moving the whole obstacle, with a large energy cost, or by causing local distortion in its shape which costs much less energy. The non-rigid obstacle also has local thermal fluctuations due to which its shape can change with time and we describe this using fluctuations in the height profile of a one dimensional interface with Kardar-Parisi-Zhang dynamics. We find the shape fluctuations of the barrier strongly affects the force generation mechanism. The qualitative nature of the force-velocity curve is crucially determined by the relative time-scale of filament and barrier dynamics. The height profile of the barrier also shows interesting variation with the external load. Our analytical calculation within mean-field theory shows reasonable agreement with our simulation results.

description: Three different types of electron‐transferring metallo‐ATPases are able to couple ATP hydrolysis to the reduction of low‐potential metal sites, thereby energizing an electron. Besides the Fe‐protein known from nitrogenase and homologous enzymes, two other kinds of ATPase with different scaffolds and cofactors are used to achieve a unidirectional, energetic, uphill electron transfer to either reduce inactive Co‐corrinoid‐containing proteins (RACE‐type activators) or a second iron‐sulfur cluster‐containing enzyme of a unique radical enzymes family (archerases). We have found a new cofactor in the latter enzyme family, that is, a double‐cubane cluster with two [4Fe4S] subclusters bridged by a sulfido ligand. An enzyme containing this cofactor catalyzes the ATP‐dependent reduction of small molecules, including acetylene. Thus, enzymes containing the double‐cubane cofactor are analogous in function and share some structural features with nitrogenases.
The Essence of Theatre as the Foundation of Law
Creators: name: Robinson, Meghan
Publisher: name: Mantle: The Annual Review of Interdisciplinary Research

description: Canada has been described as a pluralistic legal society that recognizes and values both the common law and Indigenous legal orders. However, the predominant legal order in Canada was used as a tool for the attempted colonization of Indigenous cultures across the country and is built upon a normative worldview that fundamentally contradicts Indigenous worldviews. The liberal worldview that guides the common law has concentrated on the individual and has relegated the interrelationship between community, story, and land to a facet of society that holds little importance. This article is an investigation into the relationship between theatre, story, and law, exploring the essence of theatre as a communal site of resistance against the dominant structures of a liberal worldview. It explores whether theatre, as a creative medium, could have the power to make space for a pluralistic society in which Indigenous laws and the common law are valued as equal and autonomous. This article draws on the work of Leanne Betasamosake Simpson, Glen Coulthard, and Jarrett Martineau to explore the interconnection between the natural world, story, theatre, and law.

Empowered Learners: How Martial Arts Foster Self-Regulated Learning
Creators: name: Gordon, Jessie

Year: 2023

description: Learning and academic success are often characterized by intellectual proficiency. However, they are increasingly being recognized as a multifaceted endeavour that requires a holistic approach, encompassing the social, emotional, and physical domains. The cultivation of “soft skills” such as self-regulation, critical thinking, and effective communication skills are essential for one’s success in the classroom and beyond. Such competencies, influenced by familial, community, and cultural environments, are increasingly being addressed in schools and educational settings through social-emotional learning (SEL) and self-regulated learning (SRL) methodologies. This paper explores the unique opportunity that martial arts-based interventions, characterized by their approach to psychoeducation, mindfulness, and interpersonal kinesthetic learning, provide in empowering learners. Based on existing literature, this paper illustrates the potential of martial arts-based interventions for fostering self-regulated, socially, and emotionally competent learners, enhancing their educational experiences and empowering them beyond the school environment.

True Stories—Shapeshifting between mode and metaphor
Creators: name: Haggan, Nigel
Publisher: name: Mantle: The Annual Review of Interdisciplinary Research
Year: 2023

description: For the Squamish Nation, the two peaks of Vancouver’s North Shore are twin sisters who brought lasting peace. As the “North Shore Lions” they symbolize colonial effacement of Aboriginal presence. We draw on ‘true stories’ from Indigenous, Irish, and scientific traditions to explore the tension between the ultimately unknowable ‘truth’ of mountains, salmon, and people and the ‘stories’—myths, models, maps, equations, parables, poetry, plays, paintings, and prose—that help us to grasp aspects of their mystery. Indigenous, religious and a growing number of scientific authorities argue that wisdom and well-being have physical, emotional, spiritual, and intellectual dimensions. We suggest that over-valuing the intellectual leads to the chronic stress, broken relationships, and suicide that are all too common in school and university. In other words, that the demands of academic excellence are inimical to wholistic well-being. We conclude that denigration and exclusion of emotional and spiritual intelligence is an insidious form of epistemic or cognitive injustice. Indigenous concepts of ‘good’ or ‘compassionate mind’ point to deficits in the university mission of research, teaching, and service, but also suggest ways to enrich knowledge and increase well-being.

Rescuing the concept of swimming in curved spacetime

description: It has been argued that an extended, quasi-rigid body evolving freely in curved spacetime can deviate from its natural trajectory by simply performing cyclic deformations. More interestingly, in the limit of rapid cycles, the amount of deviation, per cycle, would depend on the sequence of deformations but not on how fast they are performed -- like the motion of a swimmer at low Reynolds number. Here, however, we show that the original analysis which supported this idea is inappropriate to investigate the motion of extended bodies in the context of general relativity, rendering its quantitative results invalid and casting doubts on the reality of this swimming effect. We illustrate this by showing that the original analysis leads to a non-zero deviation even in a scenario where no swimming can possibly occur. Notwithstanding, by applying a fully covariant, local formalism, we show that swimming in curved spacetime is indeed possible and that, in general, its magnitude can be of the same order as (fortuitously) anticipated -- although it is highly suppressed in the particular scenario where it was originally investigated.

description: The synthesis, characterization and crystal structure of a dimethylformamide (DMF) coordinated magnesium tetraphenylporphyrin, [Mg(TPP)(DMF)]·CH2Cl2 (1), is described. Theoretical studies including optimization of the geometry, simulation of the electronic spectrum and binding energy calculations were performed for the complexes using the DFT method to understand the axial coordination in magnesium porphyrins. To get insight into intermolecular interactions Hirshfeld surface analyses and plotting of the 2D fingerprint was performed. Antioxidant activity was measured for the complex which showed enhanced antioxidant activity in the presence of DMF.

description: Non-equilibrium systems lack an explicit characterisation of their steady state like the Boltzmann distribution for equilibrium systems. This has drastic consequences for the inference of parameters of a model when its dynamics lacks detailed balance. Such non-equilibrium systems occur naturally in applications like neural networks or gene regulatory networks. Here, we focus on the paradigmatic asymmetric Ising model and show that we can learn its parameters from independent samples of the non-equilibrium steady state. We present both an exact inference algorithm and a computationally more efficient, approximate algorithm for weak interactions based on a systematic expansion around mean-field theory. Obtaining expressions for magnetisations, two- and three-point spin correlations, we establish that these observables are sufficient to infer the model parameters. Further, we discuss the symmetries characterising the different orders of the expansion around the mean field and show how different types of dynamics can be distinguished on the basis of samples from the non-equilibrium steady state.

description: BDDC and FETI-DP algorithms are developed for three-dimensional elliptic problems with adaptively enriched coarse components. It is known that these enriched components are necessary in the development of robust preconditioners. To form the adaptive coarse components, carefully designed generalized eigenvalue problems are introduced for each faces and edges, and the coarse components are formed by using eigenvectors with their corresponding eigenvalues larger than a given tolerance $λ_{TOL}$. Upper bounds for condition numbers of the preconditioned systems are shown to be $C λ_{TOL}$, with the constant $C$ depending only on the maximum number of edges and faces per subdomain, and the maximum number of subdomains sharing an edge. Numerical results are presented to test the robustness of the proposed approach.

Comparing the results of very accurate measurements of atomic clock transitions performed at different time in the year allows us to study the dependence of the atomic frequencies on the gravitational potential. We examine the measurement data for the ratio of the frequencies in Hg$^+$ and Al$^+$ clock transitions and absolute frequency measurements (with respect to caesium frequency standard) for Dy, Sr, H, hyperfine transitions in Rb and H, and obtain significantly improved limits on the values of the gravity related parameter of the Einstein Equivalence Principle violating term in the Standard Model Extension Hamiltonian $c_{00} = (3.0 \pm 5.7) \times 10^{-7}$ and the parameter for the gravity-related variation of the fine structure constant $κ_α = (-5.3 \pm 10) \times 10^{-8}$.

description: The operation of organic optoelectronic devices relies notably on the bulk properties of compound molecular species, but even more so on the influence of interfaces thereof. The identification and characterization of elemental processes in these critical sections of a device thereby requires well-defined interfaces with low defect density. In this context titanyl phthalocyanine (TiOPc) arises as an excellent candidate that reveals the formation of a stable bilayer structure with a characteristic "up-down" molecular arrangement that optimizes the dipole-dipole interaction within the bilayer. In our experimental study, long-range ordered TiOPc bilayers have been grown on Ag(111) surfaces and analyzed using infrared absorption spectroscopy and scanning tunneling microscopy. By monitoring the prominent Ti=O stretching mode in IRAS and identifying local configurations in STM, a microscopic model for the growth of TiOPc bilayers on Ag(111) is suggested. We demonstrate that defect structures within these bilayers lead to characteristic vibrational signatures which react sensitively to the local environment of the molecules. Thermal desorption spectroscopy reveals a high thermal stability of the TiOPc bilayer up to 500 K, which is attributed to hydrogen bonds between oxygen of the titanyl unit and the hydrogen rim of phthalocyanines in the second layer, in addition to contributions arising from the oppositely oriented axial dipole moments and the ubiquitous van der Waals interactions.

On (Secure) Information flow for Multiple-Unicast Sessions: Analysis with Butterfly Network

description: This paper considers a class of wireline networks, derived from the well-known butterfly network, over which two independent unicast sessions take place simultaneously. The main objectives are to understand when network coding type of operations are beneficial with and without security considerations and to derive the ultimate gains that cooperation among sources and sinks can bring. Towards these goals, the capacity region of the butterfly network with arbitrary edge capacities is first derived. It is then shown that no rate can be guaranteed over this network under security considerations, when an eavesdropper wiretaps any of the links. Three variants of the butterfly network, such as the case of co-located sources, are analyzed as well and their secure and non-secure capacity regions are characterized. By using the butterfly network and its variants as building blocks, these results can be used to design high-throughput achieving transmission schemes for general multiple-unicast networks.

description: Two new ternary Cd(II) coordination polymers, [Cd2(L)(tbip)2]n (1) and {[Cd(L)0.5(1,4-NDC)]·0.4H2O}n (2) (H2tbip = 5-tert-butylisophthalic acid, 1,4-H2NDC = 1,4-naphthalenedicarboxylic acid and L = 1,4-bis(2-ethylbenzimidazol-1-ylmethyl)benzene), were hydrothermally synthesized and characterized via single-crystal X-ray diffraction, IR spectroscopy, powder X-ray diffraction (PXRD) and thermogravimetric analysis. 1 is a 1-D linear chain, while 2 exhibits a 3-D framework, which can be defined as a 3-D xah (sqc320) topology with the Schläfli symbol of {42.62.82}{46.64}. 1 and 2 remained stable in a pH range of 4.0–13.0 and 3.0–13.0, respectively. 1 and 2 displayed excellent luminescent sensing abilities for Fe3+ ions and tetracycline with high sensitivity and selectivity.

description: We demonstrate experimentally the operation of a deterministic Josephson ratchet with tunable asymmetry. The ratchet is based on a $φ$ Josephson junction with a ferromagnetic barrier operating in the underdamped regime. The system is probed also under the action of an additional dc current, which acts as a counter force trying to stop the ratchet. Under these conditions the ratchet works against the counter force, thus producing a non-zero output power. Finally, we estimate the efficiency of the $φ$ Josephson junction ratchet.

description: The reaction of indium bis(trimethylsilyl)amide with a series of sterically varied carboxylic acids in toluene followed by the addition of methanol led to the isolation of a series of hydronium-ammonium indium carboxylates (([H3O]x[NH4]y)In(ORc)z). These derivatives were structurally characterized as 3([H3O]0.20[NH4]0.80)[In(OFc)6] (1), ([H3O]0.45[NH4]0.55)[In(OAc)4] (2), ([H3O]0.35[NH4]0.65)[In(OBc)4]·3H-OBc (3) and ([H3O]0.70[NH4]0.30)[In(ONc)4]·2H-ONc (4), where OFc = O2CH, OAc = O2CCH3, OPc = O2CCH(CH3)2, OBc = O2CC(CH3)3, ONc = O2CCH2C(CH3)3 and py = pyridine. For 1, an octahedral arrangement of six OFc ligands coordinated to the In metal center was solved, with three counter cations located in the lattice to balance the charge. Based on population refinements that yielded values larger than unity for NH4+ only, a mixed [H3O]:[NH4] cation ratio was proposed, evaluated, and found to yield a better structure for 1 with an approximate 20:80 ratio. For 2–4, the distorted dodecahedral metal centers are chelated by four ORc moieties and charge balanced by a single, mixed [H3O]:[NH4] cation (see formulas above for ratios) in the lattice. For 3 and 4, H-ORc ligands were also located in the lattice with extensive H-bonding to the parent molecule. The OPc derivatives were only isolable in the presence of pyridine forming crystals of [In(OPc)3]·NH3 (5) and [In(k2-OPc)2(µ-OPc)(py)]n (5a).

description: Two new binuclear complexes, [Ni2L(OAc)2(H2O)]ClO4·H2O·CH2Cl2 (1) and [Zn2L(OAc)2]ClO4·CHCl3·0.5C6H12 (2), have been synthesized by using 2-[N,N-di(2-pyridylmethyl)aminomethyl]-6-(2-imidazolylmethyl)aminomethyl-4-methylphenol (HL) as a ligand. Complexes 1 and 2 have been characterized by FT-IR, powder X-ray diffraction, elemental analysis and single-crystal X-ray diffraction. X-ray crystallographic analyses show that 1 crystallizes in the triclinic P-1 space group, while 2 in the monoclinic C2/c space group. Both Ni1 and Ni2 in 1 are six-coordinate octahedra with a [Ni1O3N3] and [Ni2O4N2] configuration. In 2, the six-coordinate Zn1 cation displays a distorted octahedral [Zn1O3N3] configuration, while the five-coordinate Zn2 cation has a trigonal bipyramidal [Zn2O2N3] geometry. The intermolecular interactions in 1 and 2 have been investigated by 3D Hirshfeld surface analyses and 2D fingerprint plots to show that the prominent interactions are H···H and O···H/H···O contacts in 1 and H···H and Cl···H/H···Cl contacts in 2. Notably, the fluorescence emission of 2 has larger intensity than that of the free HL.

description: Lanthanide complexes of Sm(III), Nd(III), and Dy(III) with a Schiff base ligand, (potassium2-((4-hydroxy-3-methoxybenzylidene)amino)acetate, derived from condensation of 4-hydroxy-3-methoxybenzaldehyde and 2-aminoethanoic acid were synthesized. The compounds were characterized by elemental analysis, IR, UV–Vis, 1H-NMR, ESI-MS, photoluminescence spectra, thermogravimetric analysis, magnetic susceptibility, and molar conductivity measurements. No well-defined peaks were observed in X-ray diffractograms of the synthesized complexes, indicating an amorphous nature. The Schiff base ligand is tridentate and coordinated with the metal ion through phenolic oxygen, azomethine nitrogen, and carboxylic oxygen. Thermal properties of the metal complexes were studied using thermogravimetric analysis (TG/DTG) and revealed good thermal stability. The photocatalytic efficiencies of the complexes were explored using solar water-splitting. The optical band gaps (Eg) were measured and found to be 2.94, 2.86, and 2.82 eV for Sm(III), Nd(III), and Dy(III) complexes, respectively. These values indicated the semi-conducting nature of the investigated complexes. At room temperature, samarium and dysprosium complexes showed characteristic luminescence of the central metal ions ascribed to the efficient transfer of energy from the Schiff base ligand to the metal center under excitation at 390 nm. The binding properties of these complexes with calf-thymus DNA (CT-DNA) have been investigated using absorption spectrophotometry and fluorescence studies. The physicochemical properties such as hydrodynamic size, zeta potential, and stability of the DNA/complexes were also investigated. DNA cleavage activities of the compounds were assayed using the Agarose gel electrophoresis method. In-vitro antimicrobial activities of the compounds were screened against selected pathogenic strains by Agar well diffusion method.

description: The evolution of highly efficient adsorbents has received attention around the world due to the importance of removing pollution from water. In the current work, a new and stable silica/coordination polymer nanoporous composite was prepared via the layer-by-layer method and characterized with various physicochemical methods. Aminopropyl-functionalized SiO2 was consecutively coated with Ni2+ and glutaric acid (GA) in 10 steps to prepare SiO2/Ni-GA. The removal efficiency of SiO2-based nanoporous composite towards cationic and anionic dyes was considered at room temperature. The results showed that SiO2/Ni-GA is a good adsorbent for all selected dyes (Congo red, CR; methyl orange, MO; and malachite green, MG). However, CR with higher removal efficiency (94%) was selected for further investigations. The high removal efficiency of SiO2/Ni-GA towards CR is related to hydrogen bonding and relatively good surface area. The adsorption process was well fitted with the second-order kinetic model and the recovered adsorbent was shown to be reusable for three consecutive cycles.

description: We propose and experimentally demonstrate a tunable band-notched line-defect waveguide in a surface-wave photonic crystal, which consists of a straight line-defect waveguide and side-coupled defect cavities. A tunable narrow stopband can be observed in the broadband transmission spectra. We also demonstrate that both the filtering levels and filtering frequencies of the band-notched line-defect waveguide can be conveniently tuned through changing the total number and the pillar height of the side-coupled defect cavities. The band-notch function is based on the idea that the propagating surface modes with the resonance frequencies of the side-coupled defect cavities will be tightly localized around the defect sites, being filtered from the waveguide output. Transmission spectra measurements and direct near-field profiles imaging are performed at microwave frequencies to verify our idea and design. These results may enable new band-notched devices design and provide routes for the realization of tunable surface-wave filters on a single metal surface.

description: Die Dispersion elektrisch leitfähiger Nanopartikel in einer Polymermatrix ermöglicht die Herstellung einer nützlichen Materialklasse: elektrisch leitfähige Polymerkomposite. Die gezielte Einstellung der elektrischen Leitfähigkeit des leitfähigen Komposits ist jedoch nicht trivial, da viele Material- und Verarbeitungsparameter die Partikel-Netzwerkstruktur im Komposit beeinflussen die letztlich für die elektrische Leitfähigkeit ausschlaggebend ist. In dieser Arbeit werden die elektrischen Eigenschaften von Epoxid-Nanokompositen mit Kohlenstoff-Nanopartikeln als leitfähigem Füllstoff für verschiedene Verarbeitungsbedingungen untersucht. Im Unterschied zu einem klassischen Formgebungsverfahren für Epoxidmaterialien wird die Anwendung von elektrischen Feldern während des Aushärtungsprozesses als zusätzlicher Prozessparameter benutzt. Elektrische Felder werden während des Aushärtens an die Nanokomposite angelegt, wodurch die elektrischen Eigenschaften des Endmaterials durch Induktion von Polarisations- und Dipol-Wechselwirkungen zwischen den leitenden Partikeln (Dielektrophorese) beeinflusst werden. Diese führen zu einer neuen, und im Hinblick auf die elektrische Leitfähigkeit vorteilhaften Mikro- und Nanostruktur des leitfähigen Netzwerks. Dieses Phänomen wird für ein System von einwandigen Kohlenstoff-Nanoröhren in einer Epoxidharzmatrix im Hinblick auf den Einfluss verschiedener Verarbeitungsparameter auf die elektrische Leitfähigkeit des Systems untersucht. Darauf aufbauend wird ein skalierbares Verfahren auf der Grundlage des Harzinjektionsverfahrens zur Herstellung von Nanokompositen unter elektrischen Feldern entwickelt. Für ein besseres Verständnis der Mechanismen, die der Wirkung elektrischer Felder auf die Rotation und die Verschaltung von SWCNTs werden die eigenen Ergebnisse mit Simulationen kooperierender Wissenschaftler der Anáhuac Mayab Universit¨1t (Merida, Mexiko) und das Imperial College London (Vereinigtes Königreich) verglichen.

description: The Higgs boson mass and top quark mass imply that the Higgs quartic coupling vanishes around the scale of $10^9 - 10^{13}$ GeV, depending on the precise value of the top quark mass. The vanishing quartic coupling can be naturally addressed if the Higgs field originates from a 5-dimensional gauge field and the 5th dimension is compactified at the scale of the vanishing Higgs quartic coupling, which is a scenario based on gauge-Higgs unification. We present a general prediction of the scenario on the proton decay process $p \to π^0 e^+$. In many gauge-Higgs unification models, the 1st generation fermions are localized towards an orbifold fixed point in order to realize the realistic Yukawa couplings. Hence, four-fermion operators responsible for the proton decay can appear with a suppression of the 5-dimensional Planck scale (not the 4-dimensional Planck scale). Since the 5-dimensional Planck scale is connected to the compactification scale, we have a correlation between the proton partial decay width and the top quark mass. We show that the future Hyper-Kamiokande experiment may discover the proton decay if the top quark pole mass is larger than about 172.5 GeV.

description: [Background] Reactions with stable beams have demonstrated a strong interplay between nuclear structure and fusion. Exotic beam facilities open new perspectives to understand the impact of neutron skin, large isospin, and weak binding energies on fusion. Microscopic theories of fusion are required to guide future experiments. [Purpose] To investigate new effects of exotic structures and dynamics in near-barrier fusion with exotic nuclei. [Method] Microscopic approaches based on the Hartree-Fock (HF) mean-field theory are used for studying fusion barriers in $^{40-54}$Ca+$^{116}$Sn reactions for even isotopes. Bare potential barriers are obtained assuming frozen HF ground-state densities. Dynamical effects on the barrier are accounted for in time-dependent Hartree-Fock (TDHF) calculations of the collisions. Vibrational couplings are studied in the coupled-channel framework and near-barrier nucleon transfer is investigated with TDHF calculations. [Results] The development of a neutron skin in exotic calcium isotopes strongly lowers the bare potential barrier. However, this static effect is not apparent when dynamical effects are included. On the contrary, a fusion hindrance is observed in TDHF calculations with the most neutron rich calcium isotopes which cannot be explained by vibrational couplings. Transfer reactions are also important in these systems due to charge equilibration processes. [Conclusions] Despite its impact on the bare potential, the neutron skin is not seen as playing an important role in the fusion dynamics. However, the charge transfer with exotic projectiles could lead to an increase of the Coulomb repulsion between the fragments, suppressing fusion. The effect of transfer and dissipative mechanisms on fusion with exotic nuclei deserve further studies.

description: Introduction: The aim of this study is to determine the current situation and needs of social workers in order to develop an elderly health education program for social workers. Materials and methods: The research is of cross-sectional type; It was conducted with 1619 social workers. In the study, data was collected using the Geriatric Social Work Competency Scale, UCLA Geriatric Attitudes Scale and Google Forms. The Geriatric Social Work Competency Scale consists of four subscales (value, assessment, intervention and services) and includes 40 items. The score that can be obtained from the scale varies between 40-160. The UCLA Geriatric Attitudes Scale includes 14 items. The score that can be obtained from the scale is between 14-70. Both scales are scored with a 5-point Likert scale. The data was analysed using the IBM SPSS Statistics 26.0 program. Results: 53.8% of the participants were women; the median age is 32. As a result of the average score obtained from the Geriatric Social Work Competency Scale, it was determined that the geriatric competencies of social workers were not very high, there was a negative relationship between age and competency, a positive relationship between professional experience and value and evaluation, and a positive relationship between the number of elderly people lived with and competency. As a result of the UCLA Geriatric Attitudes Scale average score, it was determined that there was a negative relationship between the age of social workers and their attitudes towards the elderly, there was a positive relationship between professional experience and attitude, and in-service training about old age had a positive effect on attitudes. Social workers are below the average of 43.3% value, 45.2% evaluation, 46% intervention, 47.6% services subscales. Conclusion: Social workers need a training program to be developed for elderly health. Geriatric competence and attitude change according to age, experience in the field, graduated faculty, in-service training on old age, and living with the elderly.

description: We present phase curves of Jupiter from 0-140 degrees as measured in multiple optical bandpasses by Cassini/ISS during the Millennium flyby of Jupiter in late 2000 to early 2001. Phase curves are of interest for studying the energy balance of Jupiter and understanding the scattering behavior of Jupiter as an exoplanet analog. We find that Jupiter is significantly darker at partial phases than an idealized Lambertian planet by roughly 25% and is not well fit by Jupiter-like exoplanet atmospheric models across all wavelengths. We provide analytic fits to Jupiter's phase function in several Cassini/ISS imaging filter bandpasses. In addition, these observations show that Jupiter's color is more variable with phase angle than predicted by models. Therefore, the color of even a near Jupiter-twin planet observed at a partial phase cannot be assumed to be comparable to that of Jupiter at full phase. We discuss how WFIRST and other future direct-imaging missions can enhance the study of cool giants.

description: Reaction of CuX2·nH2O (X = Cl, n = 2; X = Br, n = 0) with 2-amino-5-methylpyridine (5MAP) in acetonitrile yielded [(5MAP)2CuX2]2 (1, Cl; 2, Br). The compounds are isomorphous and crystallize in the monoclinic space group P21/n as bihalide bridged dimers. Variable temperature magnetic measurements show very weak exchange in the two compounds (-2.1(1) K) which may correlate with previously proposed magnetostructural correlations for bihalide bridged Cu(II) dimers. In attempts to prepare 2 in 2-butanone as solvent, [(3-Br-2-Et-5-Mepyrpy)(CH3CO2)4Cu2] (3) was serendipitously isolated (3-Br-2-Et-5-Mepyrpy = 3-bromo-2-ethyl-5-methyl-7H-pyrrolido[2,3-b]pyridinium). The bicyclic ligand was synthesized in situ by condensation of 5MAP with the solvent; the acetate ions were generated by copper(II) catalyzed Baeyer-Villiger oxidation of the solvent. A mechanism for the synthesis is proposed. The resulting Cu-paddlewheel compound exhibits strong (-400 K) antiferromagnetic interactions.

Dark Matter Phenomenology of SM and Enlarged Higgs Sectors Extended with Vector Like Leptons

description: We will investigate the scenario in which the Standard Model (SM) Higgs sector and its 2-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the interactions between the Standard Model and a fermionic Dark Matter (DM) candidate. The latter is the lightest stable neutral particle of a family of vector-like leptons (VLLs). We will provide an extensive overview of this scenario combining the constraints purely coming from DM phenomenology with more general constraints like Electro-weak Precision Tests (EWPT) as well as with collider searches. In the case that the new fermionic sector interacts with the SM Higgs sector, constraints from DM phenomenology force the new states to lie above the TeV scale. This requirement is relaxed in the case of 2HDM. Nevertheless, strong constraints coming from Electroweak Precision Tests (EWPT) and the Renormalization Group Equations (RGEs) limit the impact of VLFs on collider phenomenology.
