description: Our project aimed to increase knowledge of noninvasive diagnostic modalities (including bone radiotracer scintigraphy), raise suspicion of transthyretin cardiac amyloidosis (ATTR-CA), and improve cardiology team member’s awareness and knowledge of shared decision-making (SDM), as well as the quality of SDM communication between cardiology team members and patients. An online educational module and survey was developed and cardiology team members in Colorado, USA, were invited to participate. This online educational module included various important topics related to ATTR-CA (e.g., the cause of ATTR-CA, endomyocardial biopsy, and noninvasive methods to diagnose ATTR-CA) and SDM (e.g., benefits of SDM, the role of SDM in the diagnosis of ATTR-CA, implementation of SDM in cardiology practice, and the 3-talk model). There were 34 survey respondents, over one-third of whom were cardiologists. Most respondents agreed on the importance of diagnosing ATTR-CA at an early stage, and about three-quarters of the survey takers agreed that bone scintigraphy can reliably diagnose ATTR-CA without the need for endomyocardial biopsy. Concern over increased time commitment was the leading barrier to the implementation of SDM in respondents’ clinical practice. The majority of respondents identified the correct answer regarding ATTR-CA and SDM after reading the online educational module. This improvement in scores after exposure to the online educational module was statistically significant. Baseline knowledge and awareness of various issues related to ATTR-CA was relatively low among cardiology team members. Participants’ knowledge was enhanced through our effective online educational program. Prospective educational projects focused on various methods of detecting ATTR-CA as well as other amyloid conditions in diverse clinical settings will remain important.

description: Earth's magnetotail is an excellent laboratory to study the interplay of reconnection and turbulence in determining electron energization. The process of formation of a power law tail during turbulent reconnection is a documented fact still in need of a comprehensive explanation. We conduct a massively parallel particle in cell 3D simulation and use enhanced statistical resolution of the high energy range of the particle velocities to study how reconnection creates the conditions for the tail to be formed. The process is not direct acceleration by the coherent, laminar, reconnection-generated electric field. Rather, reconnection causes turbulent outflows where energy exchange is dominated by a highly non-gaussian distribution of fluctuations. Electron energization is diffuse throughout the entire reconnection outflow but it is heightened by regions of intensified magnetic field such as dipolarization fronts traveling towards Earth.

Forensic analysis of microbial lipids
Creators: name: Ehrhardt, Christopher
Publisher: name: F1000Research
Year: 2015

description: Bacterial lipid profiles are dynamic features of the cell that can change rapidly in response to an organism’s growth environment. Within a forensic setting, these can provide unique clues as to the origin of microbial threat agents that are recovered as evidence, particularly Bacillus spores. Phospholipids contain a hydrophobic tail comprised of long-chain fatty acids. The types of fatty acid structures and their relative abundance within the cell are heavily influenced by the composition of the growth medium and, specifically, the source of complex carbon/nitrogen. Additives such as tryptone (enzymatic digest of casein) and soy extract cause an increase in the abundance of branched-odd fatty acids whereas other additives such as peptone (digest of animal muscle) and brain-heart infusion lead to an increase in the proportion of straight-chained fatty acids. Other aspects of the growth medium including blood supplements, trace metal content, and the concentration of complex nutrients have a predictable effect on the abundance of individual fatty acid markers (18:1ω9c, 15:0anteiso, and 17:0iso, respectively). Because medium recipes are usually specific to the host facility or a single researcher, this information can help establish leads or exclude suspects during a forensic investigation.

Another advantage to lipid profiling of Bacillus spores is that it can be non-destructive, allowing it to be combined with other forensic analyses without any sample loss. While most of the cell’s fatty acids are localized within the membrane bilayer, preliminary experiments in our laboratory indicate that free fatty acids in the growth medium accumulate on the external surface of spores during batch culturing. Their composition is consistent with profiles generated from membrane lipids. These external fatty acids can be analyzed through the use of soft-ionization mass spectrometry (i.e. DART-MS) or chemical extraction of surface constituents followed by GC-MS profiling.

description: Em Portugal, como noutros países da bacia mediterrânica, a planta de cardo (Cynara cardunculus L.) tem sido utilizada desde tempos antigos para diversas aplicações nas áreas alimentar e da saúde. Em particular, no caso da produção artesanal de queijo de cabra e ovelha, a flor do cardo tem sido usada, muitas vezes de uma forma empírica, no processo de coagulação do leite. Esta utilização deve-se ao facto da flor possuir um conjunto de enzimas, nomeadamente proteases aspárticas, que influenciam o sabor e textura característicos destes queijos. Mais recentemente, as ferramentas desenvolvidas pela biotecnologia abrem novas perspectivas para uma produção de queijo em condições controladas e a um preço mais baixo. Neste artigo é apresentada uma revisão das ferramentas biotecnológicas disponíveis e das suas potenciais aplicações nesta indústria com importante impacto a nível nacional.

description: The sustainable development goals (SDGs) provide a strategic vision and future-oriented plan that companies, regulators and society in general are challenged to face. However, companies’ contribution to the achievement of SDGs is questioned by some critical voices. In the business context, SDGwashing refers to positively pursuing a contribution to some SDGs while ignoring the negative impact of others. The objective of this research is to study whether there is an association between pursuing SDGs of a different nature and environmental performance. Are companies pursuing the more environmental-focused SDGs, the ones with better environmental performance, compared to companies pursuing more social-focused SDGs? Thus, this work examines whether multinationals that pursue more environmental-focused SDGs have a similar level of environmental performance to those that make efforts to pursue more social-oriented SDGs. This study analyzes whether SDGwashing exists in relation to environmental performance by studying its relationship with two relevant variables of literature on environmental management: outcome-based environmental performance (through GHG emissions) and process-based environmental performance (through CDP scoring). Using a sample of multinational firms listed on the FTSE 100 index, we applied an ANOVA test and logistic regression to show whether the pursuit of both more environmental-focused SDG and more social-focused SDGs was associated with environmental performance. The results of this study offer a significant contribution to academic literature on SDGs. Our findings show that the organizational profile of multinational companies that pursue more environmental-focused SDGs differs from the organizational profile of multinationals that are pursuing more social-oriented SDGs, in terms of environmental performance. This offers empirical evidence by showing that SDGwashing exists in international business.

description: Most neutron stars are expected to be born in supernovae, but only about half of supernova remnants (SNRs) are associated with a compact object. In many cases, a supernova progenitor may have resulted in a black hole. However, there are several possible reasons why true pulsar-SNR associations may have been missed in previous surveys: The pulsar's radio beam may not be oriented towards us; the pulsar may be too faint to be detectable; or there may be an offset in the pulsar position caused by a kick. Our goal is to find new pulsars in SNRs and explore their possible association with the remnant. The search and selection of the remnants presented in this paper was inspired by the non-detection of any X-ray bright compact objects in these remnants when previously studied. Five SNRs were searched for radio pulsars with the Green Bank Telescope at 820 MHz with multiple pointings to cover the full spatial extent of the remnants. A periodicity search plus an acceleration search up to 500 m/s^2 and a single pulse search were performed for each pointing in order to detect potential isolated binary pulsars and single pulses, respectively. No new pulsars were detected in the survey. However, we were able to re-detect a known pulsar, PSR J2047+5029, near SNR G89.0+4.7. We were unable to detect the radio-quiet gamma-ray pulsar PSR J2021+4026, but we do find a flux density limit of 0.08 mJy. Our flux density limits make our survey two to 16 times more sensitive than previous surveys, while also covering the whole spatial extent of the same remnants. We discuss potential explanations for the non-detection of a pulsar in the studied SNRs and conclude that sensitivity is still the most likely factor responsible for the lack of pulsars in some remnants.

Cultural Crossroads: ASEAN's Journey towards Unity and Diversity

description: In an increasingly interconnected world, the demands of global cultural engagement compel nations to redefine their cultural identities and roles on the international stage. Subsequently, the resurgence of nativist policies has reignited debates about cultural clashes (Kokkonen and Jonas 2022), exemplified by the eradication of culture in the ongoing conflict in Ukraine. Similarly, the upcoming European elections and the prevalent nativist discourse within the EU raise concerns about the emerging focus on reestablishing strong national identities, potentially undermining what is considered to be a successful story (Sassatelli 2009) of cultural cooperation within a regional organization (RO).

Despite the acknowledgement of a common cultural heritage, ASEAN has only recently introduced explicit cultural integration policies to a similar extent as long-standing organizations such as MERCOSUR and the EU. Based on the prevailing waves of reinterpretation of culture and the increasing fluidity of borders, the regional organization found itself in need of strengthening its efforts in the endeavor to cultivate an ASEAN identity (Alamsyah 2021), not without a formidable challenge. How does the RO aim to transform the reality of economic integration, geopolitical security concerns, and mere geographical proximity into a conscious ASEAN solidarity and a sense of community that transcends ethnic divisions and narrow national interests?

This paper aims to scrutinize the cultural cooperation and integration initiatives of ASEAN through analyzing the discourse around culture in the relevant official documents, treaties, and reports, as well as the recent literature on cultural identity, diplomacy, and cooperation in the bloc. The scope is to investigate the extent to which regional cultural policies accommodate the extensive diversity of the region in its most recent ambition of establishing a unified cultural identity.

description: The anomalous charge transport observed in some strongly correlated metals raises questions as to the universal applicability of Landau Fermi liquid theory. The coherence temperature $T_{FL}$ for normal metals is usually taken to be the temperature below which $T^2$ is observed in the resistivity. Below this temperature, a Fermi liquid with well-defined quasiparticles is expected. However, metallic ruthenates in the Ruddlesden-Popper family, frequently show non-Drude low-energy optical conductivity and unusual $ω/T$ scaling, despite the frequent observation of $T^2$ dc resistivity. Herein we report time-domain THz spectroscopy measurements of several different high-quality metallic ruthenate thin films and show that the optical conductivity can be interpreted in more conventional terms. In all materials, the conductivity has a two-Drude peak lineshape at low temperature and a crossover to a one-Drude peak lineshape at higher temperatures. The two-component low-temperature conductivity is indicative of two well-separated current relaxation rates for different conduction channels. We discuss three particular possibilities for the separation of rates: (a) Strongly energy-dependent inelastic scattering; (b) an almost-conserved pseudomomentum operator that overlaps with the current, giving rise to the narrower Drude peak; (c) the presence of multiple conduction channels that undergoes a crossover to stronger interband scattering at higher temperatures. None of these scenarios require the existence of exotic quasiparticles. The results may give insight into the possible significance of Hund's coupling in determining interband coupling in these materials. Our results also show a route towards understanding the violation of Matthiessen's rule in this class of materials and deviations from the "Gurzhi" scaling relations in Fermi liquids.

description: In this work we study the individual strategies carried out by agents undergoing transactions in wealth exchange models. We analyze the role of risk propensity in the behavior of the agents and find a critical risk, such that agents with risk above that value always end up losing everything when the system approaches equilibrium. Moreover, we find that the wealth of the agents is maximum for a range of risk values that depends on particular characteristics of the model, such as the social protection factor. Our findings allow to determine a region of parameters for which the strategies of the economic agents are successful.

description: The convex hull $ψ_{n,n}$ of certain $(n!)^2$ tensors was considered recently in connection with graph isomorphism. We consider the convex hull $ψ_n$ of the $n!$ diagonals among these tensors. We show: 1. The polytope $ψ_n$ is a face of $ψ_{n,n}$. 2. Deciding if a graph $G$ has a subgraph isomorphic to $H$ reduces to optimization over $ψ_n$. 3. Optimization over $ψ_n$ reduces to optimization over $ψ_{n,n}$. In particular, this implies that the subgraph isomorphism problem reduces to optimization over $ψ_{n,n}$.

Publisher: name: Science and Technology Facilities Council
Year: 2012

description: A simple model for the charge pulse induced in a metallic surface by an approaching charge travelling at relativistic velocity is developed. It indicates that the incident charge produces strong stimulation in the bandwidth of the normal mode resonances of a typical laser target chamber chiefly in the last few centimetres of travel before the surface is reached. The Electro-Magnetic Pulse (EMP) experienced in petawatt laser shots is believed to be generated in this way by the stimulation of the chamber resonance modes by the relativistic electron pulse. This finding is used to propose that arresting the relativistic electrons in a poorly conducting material a distance of a few tens of centimetres away from the chamber wall could usefully reduce the EMP.

The role of body size in the habitat choice and foraging behaviour of juvenile coho salmon under predation risk
Creators: name: Reinhardt, Ulrich Georg
Publisher: name: University of British Columbia
Year: 2009

description: Models of behaviour in trade-off situations between foraging and predator avoidance predict that an animal's decision should depend on dynamic internal states, such as energy or hormonal levels. For example, it is predicted that willingness to risk mortality decreases with increasing assets of the forager. In this thesis, I used a combination of experimental manipulation and computer modeling to examine the influence of various dynamic states, particularly body size, on the risk taking behaviour of coho salmon (Oncorhynchus kisutch) fry. I showed that fry in semi-natural stream channels used protective cover opportunistically, associating with it only when it protected them from predators. In the laboratory, I observed habitat choice and agonistic behaviour of groups of coho fry under simulated predation risk. Bigger coho used a risky habitat less than smaller individuals. Bigger fry aggressively monopolized access to food in the absence of predation risk, but in the presence of risk, the size-dependent territorial hierarchy broke down and risk-prone small fish achieved relatively higher growth rates. Using a dynamic optimization computer model with parameters representative of coho foraging, I explored the relationship between body size and optimal foraging effort over the first feeding season. Like earlier dynamic optimization models, my model showed that the willingness to risk predation should decrease with size. In contrast to earlier models, my coho-specific model predicted that risk taking should be highest in the spring. In a final experiment, I examined the influence of feeding conditions, body size, and season on the willingness of individual coho fry to feed under simulated predation risk. As expected, bigger fish were more risk averse than small fish in the summer. This was not the case in the fall when the overall willingness to risk exposure to the predator was lower. I suggest that juvenile salmonids integrate information on their internal state and the environment into their foraging behaviour to a greater extent than previously thought. If increased risk aversion with size is common in nature, it may have important ecological consequences, for example, it may help to explain the widely reported lower mortality rate of bigger juvenile fish.

description: Recent developments in the gravitational waves interferometry require more pertinent theoretical models of gravitational waves generation and propagation. Untouched possible mechanisms of spin-2 spacetime perturbations production, we will consider their subsequent scattering on other black holes (BHs). Specifically, we consider a generalization of the Regge-Wheeler-Zerilli equations for the case of distorted BHs (BHs surrounded with matter) in Minkowski and Anti-de Sitter spacetimes, the metric potential of which obeys the Liouville equation. We establish significant differences in scattering characteristics of waves of different spins and angular momenta, including the gravitational waves, caused by losing the spherical symmetry of their propagation background. In particular, we demonstrate the strong impact of the background geometry deformation on the grey-body factors, hence on the absorption cross-sections of scattering waves, and explore the issue of stability of the background geometry upon changing the deformation degree parameters.

description: Inspired by Raychaudhuri's work, and using the equation named after him as a basic ingredient, a new singularity theorem is proved. Open non-rotating everywhere expanding universes with non-vanishing spatial average of the matter variables are severely geodesically incomplete to the past. Another way of stating the result is that, under the same conditions, any singularity-free model must have a vanishing spatial average of the energy density (and other physical variables). This is very satisfactory and provides a clear decisive difference between singular and non-singular cosmologies.

description: In this work, we employ a soft-sphere discrete element method with a cohesion implementation to model the dynamical process of sub-km-sized cohesive rubble piles under continuous spinup. The dependencies of critical spin periods $T_c$ on several material parameters for oblate rubble piles with different bulk diameters $D$ are explored. Our numerical simulations show that both the increase of interparticle cohesion and particle shape parameter in our model can strengthen the bodies, especially for the smaller ones. In addition, we find there exists some critical diameter $D_{cri,ρ}$ at which the variation trend of $T_c$ with the bulk density $ρ$ reverses. Though a greater static friction coefficient $μ_S$ can strengthen the body, this effect attains a minimum at a critical diameter $D_{cri,ϕ}$ close to $D_{cri,ρ}$. The continuum theory (analytical method) is used for comparison and two equivalent critical diameters are obtained. The numerical results were fitted with the analytical method and the ratio of the interparticle cohesion $c$ to the bulk cohesion $C$ is estimated to be roughly 88.3. We find this ratio keeps constant for different $c$ and $ρ$, while it strongly depends on the friction angle $ϕ$. Also, our numerical results further show that the dependency of $T_c$ on $ϕ$ is opposite from that predicted by the continuum theory when $D$ < $D_{cri,ϕ}$. Finally, we find that the two critical diameters happen to be close to the diameter when the mean normal stress of the body equals zero, which is the separation between the compressive regime and the tensile regime.

Perth, Australia: School of Computer and Information Science, Edith Cowan University, 2006, pp. 18–25.Abstract This paper develops a theoretical model of the internal processes of the Orientation step of Boyd’s OODA loop model. The Orientation step is important from an Information Warfare perspective as it is where the decision-maker combines their existing knowledge with new information. Any new information is a potential target for manipulation by Information Warfare attacks. The operation of the two Information Warfare attacks that target the Orientation step, deception and self-deception, are examined with the proposed model.

description: We study space-inhomogeneous quantum walks (QWs) on the integer lattice which we assign three different coin matrices to the positive part, the negative part, and the origin, respectively. We call them two-phase QWs with one defect. They cover one-defect and two-phase QWs, which have been intensively researched. Localization is one of the most characteristic properties of QWs, and various types of two-phase QWs with one defect exhibit localization. Moreover, the existence of eigenvalues is deeply related to localization. In this paper, we obtain a necessary and sufficient condition for the existence of eigenvalues. Our analytical methods are mainly based on the transfer matrix, a useful tool to generate the generalized eigenfunctions. Furthermore, we explicitly derive eigenvalues for some classes of two-phase QWs with one defect, and illustrate the range of eigenvalues on unit circles with figures. Our results include some results in previous studies, e.g. Endo et al. (2020).

description: This thesis is almost entirely devoted to studying string theory backgrounds characterized by simple geometrical and integrability properties. The archetype of this type of system is given by Wess-Zumino-Witten models, describing string propagation in a group manifold or, equivalently, a class of conformal field theories with current algebras. We study the moduli space of such models by using truly marginal deformations. Particular emphasis is placed on asymmetric deformations that, together with the CFT description, enjoy a very nice spacetime interpretation in terms of the underlying Lie algebra. Then we take a slight detour so to deal with off-shell systems. Using a renormalization-group approach we describe the relaxation towards the symmetrical equilibrium situation. In he final chapter we consider backgrounds with Ramond-Ramond field and in particular we analyze direct products of constant-curvature spaces and find solutions with hyperbolic spaces.

description: Neste trabalho objetivou-se avaliar o efeito de diferentes concentrações de biorreguladores na germinação e emergência de plântulas de jiló. O primeiro experimento foi realizado em estufa tipo BOD, avaliando-se a germinação e o vigor de sementes em função de diferentes concentrações de reguladores vegetais aplicadas via semente, sendo: 0; 100; 200 e 300 mg.L-1 de GA3; 0; 50; 100 e 150 mg.L-1 da mistura de GA4+7 + benziladenina e 0; 0,001; 0,05 e 0,1 ppm de brassinolídeo. O segundo experimento foi conduzido em casa de vegetação, sendo os tratamentos aplicados os mesmos utilizados no primeiro experimento, determinando-se a emergência de sementes de jiló. O delineamento experimental utilizado nos dois experimentos foi inteiramente casualizado com 12 tratamentos e 4 repetições. A aplicação via sementes de 300 mg.L-1 de GA3 e 150 mg.L-1 de GA4+7 + benziladenina, aumentou a porcentagem de germinação e o índice de velocidade de germinação em jiló.

description: The equivalence is established between the one-dimensional (1D) Bose-system with a finite number of particles and the system obeying the fractional (intermediate) Gentile statistics, in which the maximum occupation of single-particle energy levels is limited. The system of 1D harmonic oscillators is considered providing the model of harmonically trapped Bose-gas. The results are generalized for the system with power energy spectrum.

Electron-impact ionization and ionic fragmentation of O$_{2}$ from threshold to 120 eV energy range

description: We study the electron-impact induced ionization of O$_{2}$ from threshold to 120 eV using the electron spectroscopy method. Our approach is simple in concept and embodies the ion source with a collision chamber and a mass spectrometer with a quadruple filter as a selector for the product ions. The combination of these two devices makes it possible to unequivocally collect all energetic fragment ions formed in ionization and dissociative processes and to detect them with known efficiency. The ion source allows to vary and tune the electron-impact ionization energy and the target-gas pressure. We demonstrate that for obtaining reliable results of cross sections for inelastic processes and determining mechanisms for the formation of O$^{+}$($^{4}S,^2{D},^2{P}$) ions, it is crucial to control the electron-impact energy for production of ion and the pressure in the ion source. A comparison of our results with other experimental and theoretical data shows good agreement and proves the validity of our approach.

description: RESUMEN: La investigación disciplinar en archivística es un tema vital en el momento actual, caracterizado por profundos cambios en la sociedad y, por ende, en la disciplina. Este artículo presenta los resultados de la investigación relacionados con la evolución del concepto de archivística. La investigación se llevó a cabo mediante el método de investigación documental, que tuvo como propósito explorar los principales autores y sus definiciones de archivística desde finales del siglo XIX hasta inicios del siglo XXI. Con base en ellos se analizaron los elementos constitutivos del concepto: naturaleza, finalidad y características, lo que evidenció las lentas transformaciones que ha sufrido el concepto y la necesidad de estudiar los contextos para el fortalecimiento de la disciplina.
 ABSTRACT: Disciplinary research in archival science is a vital issue at present, characterized by profound changes in society and, therefore, in the discipline. This article presents the research results related to the evolution of the archival science concept. The research was carried out through the documentary research method, which had the purpose of exploring the main authors and their definitions of archival science from the end of the 19th century to the beginning of the 21st century. Based on them, the constitutive elements of the concept were analyzed: nature, purpose, and characteristics, which evidenced the slow transformations that the concept has undergone and the need to study the contexts to strengthen the discipline.
Benthic algal and insect responses to nutrient enrichment of an in-stream mesocosm

description: A nutrient bioassay was conducted in the Slocan River in southeastern British Columbia to evaluate potential trophic level responses in advance of whole-stream enrichment. A mesocosm approach was used to contrast periphyton and insect responses to low-level nitrogen and phosphorus treatments over an 83 d period in late summer. The nutrient bioassay was used to describe quantitatively and qualitatively benthic algal and insect relationships to manipulations of N and P concentrations and their ratios. N:P concentrations of 1:1, 3:3 and 5:5 μg-L⁻¹ and 4:1, 12:3 and 20:5 μg-L⁻¹ were used for treatment group comparisons. The experimental design consisted of six, replicated (x2) treatments and control. Although significant differences in periphyton accrual (measured as chlorophyll a biomass) were consistently demonstrated between control and treatment groups, the 4:1 treatment group was substantially higher in algal biomass than the 1:1 treatment group. Up to 4 and 8-fold differences in periphyton accrual over background were observed for the 1:1 and 4:1 treatment groups, respectively. Differences in biomass between treatment groups suggested N limitation. With the exception of the 1:1 nutrient concentration where a cyanophyte (Oscillatoria sp.) became highly abundant, all other treatments were dominated by chlorophytes and diatoms. The benthic insect response was similar to the periphyton response with up to 3-fold differences in insect abundance and a near-doubling of biomass observed in the 1:1 and 4:1 treatment groups. Differences in the amplitude and periodicity of insect diel drift cycles suggested differences in food abundance between control and treatment groups. A reduction in total insect per capita drift rate from one-half to one-third of that observed under background conditions provided further evidence in support of delayed emigration in treated channels. Taxa-specific differences in per capita drift rate between control and treatments also occurred for baetid mayflies where a drop from one-half to one-third was observed within certain nutrient ratios of each treatment group. The higher availability of food in treatment groups was further supported by larger body size of insects in both the drift and the benthos. Over the period of study, chironomid midges and baetid mayflies were the most abundant taxa. Owing to a large emigration near the end of the experiment, chironomid midges that were initially numerically dominant were replaced by mayflies, albeit at lower densities. Although insects were not considered food-limited, grazers had substantial influence on areal algal biomass. After comparing differences in taxonomic richness and trophic level response, the 4N:1P ratio was considered optimum for whole-stream application.

description: We apply Density Functional Theory (DFT) and the DFT+U technique to study the adsorption of transition metal porphine molecules on atomistically flat Au(111) surfaces. DFT calculations using the Perdew-Burke-Ernzerhof (PBE) exchange correlation functional correctly predict the palladium porphine (PdP) low-spin ground state. PdP is found to adsorb preferentially on gold in a flat geometry, not in an edgewise geometry, in qualitative agreement with experiments on substituted porphyrins. It exhibits no covalent bonding to Au(111), and the binding energy is a small fraction of an eV. The DFT+U technique, parameterized to B3LYP predicted spin state ordering of the Mn d-electrons, is found to be crucial for reproducing the correct magnetic moment and geometry of the isolated manganese porphine (MnP) molecule. Adsorption of Mn(II)P on Au(111) substantially alters the Mn ion spin state. Its interaction with the gold substrate is stronger and more site-specific than PdP. The binding can be partially reversed by applying an electric potential, which leads to significant changes in the electronic and magnetic properties of adsorbed MnP, and ~ 0.1 Angstrom, changes in the Mn-nitrogen distances within the porphine macrocycle. We conjecture that this DFT+U approach may be a useful general method for modeling first row transition metal ion complexes in a condensed-matter setting.
