description: Strong quantum fluctuations in magnetic systems can create disordered quantum spin liquid phases of matter which are not predicted by classical physics. The complexity of the exotic phenomena on display in spin liquids has led to a great deal of theoretical and experimental interest. However, understanding the fundamental nature of the excitations in these systems remains challenging. In this work, we consider the Lifshitz quantum critical point in a two-dimensional frustrated $XY$ antiferromagnet. At this point, quantum fluctuations destroy long range order, leading to the formation of an algebraic Lifshitz spin liquid. We demonstrate that the bosonic magnon excitations are long-lived and well-defined in the Lifshitz spin liquid phase, though paradoxically, the dynamic structure factor has a broad non-Lorentzian frequency distribution with no single-particle weight. We resolve this apparent contradiction by showing that the Lifshitz spin liquid suffers from an infrared catastrophe: An external physical probe always excites an infinite number of arbitrarily low energy quasiparticles, which leads to significant radiative broadening of the spectrum.

description: In this work we report results of step-by-step modeling of the oxidation of free-standing boron monolayers of different types. Results of the calculations demonstrate that the process of the oxidation is always exothermic and lead toward the formation of foam-like boron oxide films with incorporated non-oxidized small boron clusters. Some of these boron-oxide films demonstrate the presence of chemically stable magnetic centers. Evaluation of the physical properties of oxidized boprophene sheets (OBS) demonstrate it possible application in solar energy, as sensors and coating against leakage of hydrogen.

title: Generation of a Medaka Fish Model of Propionic Acidemia for Development of Novel Therapies.
Creators: name: Ginocchio, Virginia Maria
Publisher: name: The Open University
Year: 2016

description: Propionic acidemia (PA) is an autosomal recessive inborn error of metabolism caused by deficiency of the mitochondrial enzyme propionyl-CoA carboxylase (PCC). The disease presents with acute, recurrent and life-threatening crises of metabolic decompensation starting from the newborn period. Patients also suffer from multi-organ complications, neurological dysfunction, and cardiomyopathy. Despite available treatments, disease mortality and morbidity remain elevated and investigation of novel and more effective therapies is highly needed.

 I have generated a PA model in medaka fishes (Oryzias latipes) using TALENs targeting the pccb medaka gene, encoding one of the subunits of PCC. The pccbdel/del medaka recapitulates the clinical and biochemical phenotype of human patients. Affected medaka larvae showed early lethality and severe neurological impairment as shown by reduced and abnormal movements. Livers and hearts of pccbdel/del larvae exhibited increased lipid droplets, likely as a consequence of impaired mitochondrial β-oxidation. Importantly, pccbdel/del larvae showed a significant increase in the levels of propionylcarnitine (C3), the biochemical hallmark of the disease. Administration of a low-protein diet improved the survival of pccbdel/del larvae. Because PCC deficiency induces depletion of Krebs cycle intermediates, I investigated the efficacy of an anaplerotic therapy in pccbdel/del medaka fishes. The anaplerotic therapy comprising sodium citrate, ornithine α-ketoglutarate, and glutamine resulted in significant improvements of both survival and locomotor activity in pccbdel/del larvae.

 Given its small size, easy handling and large number of progeny, the PA medaka model is suitable for rapid investigation of novel drugs by large-scale drug screening. I have set a drug screening assay on whole fishes using the clinically relevant locomotor activity as read-out of the assay. This large drug screening has the potential to lead to the identification of small molecule drugs already approved for use in humans that have the potential to be rapidly translated in clinical applications.

description: We investigate the possibility to control dynamically the interactions between repulsively bound pairs of fermions (doublons) in correlated systems with off-resonant ac fields. We introduce an effective Hamiltonian that describes the physics of doublons up to the second-order in the high-frequency limit. It unveils that the doublon interaction, which is attractive in equilibrium, can be completely suppressed and then switched to repulsive by varying the power of the ac field. We show that the signature of the dynamical repulsion between doublons can be found in the single-fermion density of states averaged in time. Our results are further supported by nonequilibrium dynamical mean-field theory simulations for the half-filled Fermi-Hubbard model.

Atomic data from the Iron Project.LVIII. New radiative transition probabilities for Fe IV including fine structure
Creators: name: Nahar, Sultana N.

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We present new calculations for transition probabilities of Fe IV, with much more extensive datasets than heretofore available. The large-scale close coupling R-matrix calculations yield 1,798 LS bound states with n $\leq$ 11 and $l \leq$ 9, and corresponding transition probabilities for 138,121 dipole allowed transitions in the form of oscillator strengths $f$, line strengths $S$, and A-coeffficients for a variety of applications. This represents the largest R-matrix dataset in LS coupling for any ion under either the Opacity Project or the Iron Project. Through algebraic transformation of the LS multiplets, a total of 712,120 dipole allowed fine structure transitions for Fe IV are obtained. Observed transition energies are used together with the energy independent line strengths to derive the $f$- and the $A$-values; the adopted algorithm used calculated energies for the remainder. Present results show significantly better accuracy for the important low-lying states than previous calculations. Monochromatic and mean opacities for Fe IV are computed and compared with those obtained using the Opacity Project data. We find differences which could have important consequences for several astrophysical applications involving low ionization stages of iron.

description: Optomechanics and electromechanics have made it possible to prepare macroscopic mechanical oscillators in their quantum ground states, in quadrature squeezed states, and in entangled states of motion. In addition to coaxing ever larger and more tangible objects into a regime of quantum behavior, this new capability has encouraged ideas of using mechanical oscillators in the processing and communication of quantum information and as precision force sensors operating beyond the standard quantum limit. But the effectively linear interaction between motion and light or electricity precludes access to the broader class of quantum states of motion, such as cat states or energy squeezed states. Indeed, early optomechanical proposals noted the possibility to escape this restriction by creating strong quadratic coupling of motion to light. Although there have been experimental demonstrations of quadratically coupled optomechanical systems, these have not yet accessed nonclassical states of motion. Here we create nonclassical states by quadratically coupling motion to the energy levels of a Cooper-pair box (CPB) qubit. By monitoring the qubit's transition frequency, we detect the oscillator's phonon distribution rather than its position. Through microwave frequency drives that change both the state of the oscillator and qubit, we then dissipatively stabilize the oscillator in a state with a large mean phonon number of 43 and sub-Poissonian number fluctuations of approximately 3. In this energy squeezed state we observe a striking feature of the quadratic coupling: the recoil of the mechanical oscillator caused by qubit transitions, closely analogous to the vibronic transitions in molecules.

Finite-size effects in wave transmission through plasmonic crystals: A tale of two scales

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study optical coefficients that characterize wave propagation through layered structures called plasmonic crystals. These consist of a finite number of stacked metallic sheets embedded in dielectric hosts with a subwavelength spacing. By adjustment of the frequency, spacing, number as well as geometry of the layers, these structures may exhibit appealing transmission properties in a range of frequencies from the terahertz to the mid-infrared regime. Our approach uses a blend of analytical and numerical methods for the distinct geometries with infinite, translation invariant, flat sheets and nanoribbons. We describe the transmission of plane waves through a plasmonic crystal in comparison to an effective dielectric slab of equal total thickness that emerges from homogenization, in the limit of zero interlayer spacing. We demonstrate numerically that the replacement of the discrete plasmonic crystal by its homogenized counterpart can accurately capture a transmission coefficient akin to the extinction spectrum, even for a relatively small number of layers. We point out the role of a geometry-dependent corrector field, which expresses the effect of subwavelength surface plasmons. In particular, by use of the corrector we describe lateral resonances inherent to the nanoribbon geometry.
Healing the wounds of injustice : the effectiveness of writing interventions on the physiological, psychological, and behavioral consequences of workplace mistreatment
Creators: name: Barclay, Laurie Jeanne
Publisher: name: University of British Columbia
Year: 2010

description: Workplace injustice can have profound negative effects on victims’ physical and psychological health and their behavior [i.e. behaviour] on the job. To date, organizational justice research has tended to focus on various forms of retaliatory reactions (e.g., theft, sabotage, reducing one’s effort, badmouthing the organization and/or the boss), all of which can have negative implications for the individual and the organization. Research in the trauma and coping literature has demonstrated that writing interventions (i.e., guided expressive writing) can have beneficial effects for victims by giving them the opportunity to vent emotions and seek meaning in the event. In this dissertation, I explore the question: Can victims of workplace unfairness "heal the wounds" of injustice, defined in terms of reducing the negative physiological, psychological, and behavioral consequences associated with unfairness, by writing about the experience? Specifically, I (a) replicate previous writing interventions to experiences of organizational injustice, (b) extend the intervention to consider fairness-related outcomes (i.e., victim’s anger and retaliation), and (c) test whether incremental benefits derive from including perspective taking (i.e., considering the transgressor’s perspective) in the writing intervention. Replicating procedures from previous research (e.g., Pennebaker & Beall, 1986), participants wrote about an unfair workplace experience for 20 minutes/day across four days in one of four conditions: emotions only, thoughts only, both emotions/thoughts, or a control condition. Three additional conditions were introduced involving perspective taking. Consistent with previous research, the emotions and thoughts intervention provided the highest benefits to psychological well-being (i.e., general life satisfaction). Anger decreased in all replication conditions, whereas retaliation intentions tended to vary across conditions. The results indicated that perspective taking did not provide additional benefits to victims’ outcomes over and above the emotions/thoughts condition. Although the perspective taking intervention resulted in less anger and fewer intentions to retaliate over time, the predicted changes regarding lower attributions of blame or greater compassion toward the transgressor were not observed. The emotions/thoughts condition was found to be the most effective intervention, showing the strongest and most pervasive impact across the dependent variables.

description: For any $n > 0$ and $0 \leq m < n$, let $P_{n,m}$ be the poset of projective equivalence classes of $\{-,0,+\}$-vectors of length $n$ with sign variation bounded by $m$, ordered by reverse inclusion of the positions of zeros. Let $Δ_{n,m}$ be the order complex of $P_{n,m}$. A previous result from the third author shows that $Δ_{n,m}$ is Cohen-Macaulay over $\mathbb{Q}$ whenever $m$ is even or $m = n-1$. Hence, it follows that the $h$-vector of $Δ_{n,m}$ consists of nonnegative entries. Our main result states that $Δ_{n,m}$ is partitionable and we give an interpretation of the $h$-vector when $m$ is even or $m = n-1$. When $m = n-1$ the entries of the $h$-vector turn out to be the new Eulerian numbers of type $D$ studied by Borowiec and Młotkowski in [{\em Electron. J. Combin.}, 23(1):Paper 1.38, 13, 2016]. We then combine our main result with Klee's generalized Dehn-Sommerville relations to give a geometric proof of some facts about these Eulerian numbers of type $D$.

description: Estimation of condenser performance of two-phase passive heat spreaders with grooved wick structures is crucial in the prediction of the overall performance of the heat spreader. Whilst the evaporation problem in micro-grooves has been widely studied, studies focusing on the condensation on fin-groove systems have been scarce. Condensation on fin-groove systems is actually a multi-scale problem. Thickness of the film near the fin-groove corner can decrease to nanoscale dimensions, which requires the inclusion of nanoscale effects into the modeling. While a few previous studies investigated the effect of dispersion forces, the effect of structural forces has never been considered in the thin film condensation modeling on fin-groove systems. The present study utilizes a disjoining pressure model which considers both dispersion and structural forces. The results reveal that structural forces are able to dominate dispersion forces in certain configurations. Consequently, by intensifying the disjoining pressure, structural forces lead to a sudden change of the film profile (slope break) for subcooling values which are relevant to engineering applications.

description: The diverse steady-state spectroscopic properties of poly(di-n-octylfluorene) are addressed from a molecular-level perspective. Modeling of representative oligomers support the experimental observation of at least three distinguishable classes of conformational isomers with differing chain torsion angles. One class appears to be populated by a single compact structural isomer and this conforms to the so called beta phase. A rigorous Franck-Condon analysis of the photoluminescence in conjunction with Frenkel-type exciton band structure calculations are performed. These results accurately reproduce all major spectral features of the photoabsorption and those of singlet exciton emission.

description: We investigate how the data from various future neutrino oscillation experiments will constrain the physics parameters for a three active neutrino mixing model. The investigations properly account for the degeneracies and ambiguities associated with the phenomenology as well as estimates of experimental measurement errors. Combinations of various reactor measurements with the expected J-PARC (T2K) and NuMI offaxis (Nova) data, both with and without the increased flux associated with proton driver upgrades, are considered. The studies show how combinations of reactor and offaxis data can resolve degeneracies (e.g. the theta23 degeneracy) and give more precise information on the oscillation parameters. A primary purpose of this investigation is to establish the parameter space regions where CP violation can be discovered and where the mass hierarchy can be determined. It is found that such measurements, even with the augmented flux from proton driver upgrades, demand sin^2 (2 theta13) be fairly large and in the range where it is measurable by reactor experiments.

description: Bramante, Delgado, and Martin [Phys. Rev. D96, 063002(2017)., hereafter BDM17] extended the analytical formalism of dark matter (DM) capture in a very important way, which allows, in principle, the use of compact astrophysical objects, such as neutron stars (NS), as dark matter detectors. In this comment, we point out the existence of a region in the dark matter neutron scattering cross section $(σ_{nX})$ vs. dark matter mass $(m_{X})$ where the constraining power of this method is lost. This corresponds to a maximal temperature ($T_{crit}$) the NS has to have, in order to serve as a dark matter detector. In addition, we point out several typos and errors in BDM17 that do not affect drastically their conclusions. Moreover, we provide semi-analytical approximations for the total capture rates of dark matter particle of arbitrary mass for various limiting regimes. Those analytical approximations are used to validate our numerical results.

description: Signalling through adenosine- and adenine-nucleotide-gated receptors (purinoceptors) regulates a vast array of physiological processes in the central nervous system, including synaptic transmission. The research presented here describes a role for mitogen-activated protein kinases (MAPKs) in mediating molecular signalling cascades initiated by activation of purinoceptors in the hippocampus. In particular, it is proposed that MAPK activation is a requirement for purinoceptor-mediated presynaptic inhibition of neurotransmission. The three primary findings presented here are: (1) P2X₇ receptors are localized on mossy fiber terminals [i.e. mossy fibre terminals] where they function to inhibit mossy fiber-CA3 synaptic transmission in a pathway requiring p38 MAPK activation; (2) Adenosine A₁ receptors exist in a complex with p38 MAPK in which A₁ receptors activate p38 MAPK to decrease Schaffer-collateral-CA1 synaptic transmission; and (3) Sequential activation of C-Jun N-terminal kinase (JNK) following p38 MAPK activation is also required for A₁ receptor-mediated synaptic depression. Immunocytochemistry was used to demonstrate that P2X₇ receptors are abundant on presynaptic terminals of mossy fiber synapses in the rat hippocampus. Western blotting was used to show increases in the phosphorylation state of p38 MAPK and JNK following A₁ receptor stimulation in the CA1 region. Co-immunoprecipitation showed that A₁ receptors are physically associated with p38 MAPK and JNK in the hippocampus. Synaptic function was assessed using field excitatory postsynaptic potentials (fEPSPs) evoked in stratum lucidum in the CA3 region or in stratum radiatum in the CA1 region of rat hippocampal slices. Selective stimulation of P2X₇ receptors with the agonist Bz-ATP potently decreased mossy fiber-CA3 synaptic depression and this was blocked by the P2X₇ antagonist oxidized-ATP, but not by the P2X₁₋₃,₅,₆ antagonist, PPADs or the P2Y antagonist, RB2. Bz-ATP-induced synaptic depression was blocked by the p38 MAPK inhibitor SB203580. Stimulation of A₁ receptors with exogenous adenosine, endogenous adenosine released during hypoxia, or the agonist N⁶-cyclopentyladenosine (CPA) depressed evoked tEPSPs in the CA1 region. These inhibitory responses were blocked with the A₁ receptor antagonist 8-cyclopentyl-1,3-dipropylxanthine (DPCPX), the p38 MAPK inhibitors SB203580 and SB202190, and the JNK inhibitors SP600125 and JNK Inhibitor V. These results suggest that the inhibitory actions of purinoceptors requires the activation of p38 MAPK and JNK in the hippocampus.

description: We propose a general machine learning-based framework for building an accurate and widely-applicable energy functional within the framework of generalized Kohn-Sham density functional theory. To this end, we develop a way of training self-consistent models that are capable of taking large datasets from different systems and different kinds of labels. We demonstrate that the functional that results from this training procedure gives chemically accurate predictions on energy, force, dipole, and electron density for a large class of molecules. It can be continuously improved when more and more data are available.

description: We study the effect of mesoscopic fluctuations on a magnetic impurity coupled to a spatially confined electron gas with a temperature in the mesoscopic range (i.e. between the mean level spacing $Δ$ and the Thouless energy $E_{\rm Th}$). Comparing ``poor-man's scaling'' with exact Quantum Monte Carlo, we find that for temperatures larger than the Kondo temperature, many aspects of the fluctuations can be captured by the perturbative technique. Using this technique in conjunction with semi-classical approximations, we are able to calculate the mesoscopic fluctuations for a wide variety of systems. For temperatures smaller than the Kondo temperature, we find large fluctuations and deviations from the universal behavior.

description: An approach to implementing variational Bayesian inference in biological systems is considered, under which the thermodynamic free energy of a system directly encodes its variational free energy. In the case of the brain, this assumption places constraints on the neuronal encoding of generative and recognition densities, in particular requiring a stochastic population code. The resulting relationship between thermodynamic and variational free energies is prefigured in mind-brain identity theses in philosophy and in the Gestalt hypothesis of psychophysical isomorphism.

description: Lameness due to bacterial chondronecrosis with osteomyelitis (BCO) is an infection of weak bone by opportunistic bacteria that infiltrate the circulation as a result of immune suppression or gastrointestinal deterioration. One mitigating strategy is the dietary inclusion of products to support overall broiler robustness and bone health. To test the ability of phytase and stimbiotic supplements to alleviate lameness, broilers were reared for 56 days on either litter flooring or wire ramps to induce BCO and fed one of 6 diets: positive control (PC); negative control (NC, Ca and P deficient); PC plus stimbiotic; PC plus stimbiotic and phytase; NC plus phytase; NC plus stimbiotic and phytase. Stimbiotic was added at 100 g/tonne, and phytase at 3000 FTU/kg. Birds were scored for BCO on d56, or when culled for lameness. All-cause mortality was higher on ramp as compared to litter, regardless of treatment. Lameness was significantly induced by wire ramps, with the greatest incidence in the NC diet. Importantly, the addition of stimbiotic and phytase to the NC diet reduced lameness by ∼50%. Femur BCO scores were similarly reduced, with ∼60% of femurs scored ≥1 in the NC group compared to 30–37% in stimbiotic and phytase supplemented groups, indicating that these supplements can impact the onset/progression of lameness in poultry. There was no correlation between plasma and bone inositol levels; however, wire flooring reduced bone inositol, regardless of diet. Additionally, blood pH was greater and circulating PCO2, HCO3, BE, TCO2, K, haematocrit, and haemoglobin were lower on ramp compared to litter flooring. Wire ramp model reproducibly induced lameness/BCO in broilers.Treatments did not affect growth, but phytase with stimbiotic significantly reduced BCO.Phytase increased circulating inositol, and wire flooring decreased bone inositol.

description: We have examined the interstellar scintillations of the pulsars in the double pulsar binary system. Near the time of the eclipse of pulsar A by the magnetosphere of B, the scintillations from both pulsars should be highly correlated because the radiation is passing through the same interstellar plasma. We report confirmation of this effect using 820 and 1400 MHz observations made with the Green Bank Telescope. The correlation allows us to constrain the projected relative position of the two pulsars at closest approach to be 4000 +/- 2000 km, corresponding to an inclination that is only 0.29 +/-0.14 degrees away from 90 degrees. It also produces a two-dimensional map of the spatial correlation of the interstellar scintillation. This shows that the interstellar medium in the direction of the pulsars is significantly anisotropic. When this anisotropy is included in the orbital fitting, the transverse velocity of the center of mass is reduced from the previously published value of 141 +/- 8.5 km/s to 66 +/- 15 km/s.

Why and when is pausing beneficial in quantum annealing?

description: Recent empirical results using quantum annealing hardware have shown that mid anneal pausing has a surprisingly beneficial impact on the probability of finding the ground state for of a variety of problems. A theoretical explanation of this phenomenon has thus far been lacking. Here we provide an analysis of pausing using a master equation framework, and derive conditions for the strategy to result in a success probability enhancement. The conditions, which we identify through numerical simulations and then prove to be sufficient, require that relative to the pause duration the relaxation rate is large and decreasing right after crossing the minimum gap, small and decreasing at the end of the anneal, and is also cumulatively small over this interval, in the sense that the system does not thermally equilibrate. This establishes that the observed success probability enhancement can be attributed to incomplete quantum relaxation, i.e., is a form of beneficial non-equilibrium coupling to the environment.

description: We study the diffusion of a particle on a random lattice with fluctuating local connectivity of average value q. This model is a basic description of relaxation processes in random media with geometrical defects. We analyze here the asymptotic behavior of the eigenvalue distribution for the Laplacian operator. We found that the localized states outside the mobility band and observed by Biroli and Monasson (1999, J. Phys. A: Math. Gen. 32 L255), in a previous numerical analysis, are described by saddle point solutions that breaks the rotational symmetry of the main action in the real space. The density of states is characterized asymptotically by a series of peaks with periodicity 1/q.

description: The article presents a place of agricultural holdings and enterprises in the food chain. It demonstrates that, despite a decline in both the share of agriculture in: the Gross Domestic Product, employment, and the share of food expenditure in household expenditure, agricultural holdings and enterprises constitute a fundamental and inalienable link in the food chain. Agri-food products determine the positive balance of foreign trade in these products. Furthermore, the article discusses efficiency drivers for the food chain. The most important ones include cooperative ties between the links in the chain.
