description: In a superconductor, the ratio of the carrier density, $n$, to their effective mass, $m^*$, is a fundamental property directly reflecting the length scale of the superfluid flow, the London penetration depth, $λ_L$. In two dimensional systems, this ratio $n/m^*$ ($\sim 1/λ_L^2$) determines the effective Fermi temperature, $T_F$. We report a sharp peak in the $x$-dependence of $λ_L$ at zero temperature in clean samples of BaFe$_2$(As$_{1-x}$P$_x$)$_2$ at the optimum composition $x = 0.30$, where the superconducting transition temperature $T_c$ reaches a maximum of 30\,K. This structure may arise from quantum fluctuations associated with a quantum critical point (QCP). The ratio of $T_c/T_F$ at $x = 0.30$ is enhanced, implying a possible crossover towards the Bose-Einstein condensate limit driven by quantum criticality.

Variation in displacement energies due to isospin nonconserving forces

description: For mirror nuclei with masses A=42-95, the effects of isospin nonconserving nuclear forces are studied with nuclear shell model using the Coulomb displacement energy and triplet displacement energy as probes. It is shown that the characteristic behavior of the displacement energies can be well reproduced if the isovector and isotensor nuclear interactions with J=0 and T=1 are introduced into the f7/2 shell. These forces, with their strengths being found consistent with the nucleon-nucleon scattering data, tend to modify nuclear binding energies near the N=Z line. At present, no evidence is found that these forces are needed for the upper fp-shell. Theoretical one- and two-proton separation energies are predicted accordingly, and locations of the proton drip-line are thereby suggested.

description: In the past four decades, great efforts have been made worldwide to collect accurate ground-based measurements of solar radiation. This comes in light of the growing interest in climate change, of which solar radiation is a critical factor. At the same time, solar-radiation-based energy is one of the most promising energy alternatives to fossil fuels. This present thesis is primarily based on irradiance data collected at different orientations. The measurements were conducted over several years in Hannover, Germany, through the use of silicon solar sensors and thermopile pyranometers to investigate the following research questions: (1) How accurate are the transposition models that estimate the global and diffuse solar irradiance on tilted planes; (2) is there an alternative concept for increasing self-consumption via use another orientation of photovoltaic (PV) systems than the south direction; and (3) how accurate are the silicon-based irradiance sensors, and what is the deviation to thermopile sensors?

description: This paper reports on the improvement of the differential current gain in the spin-torque transistor based on two independent innovations, viz.the use of magnetic insulators and the spin Hall effect. Since, except for a few examples, spin transistors lack the current gain that is essential for many applications, spintronics and magnetic information technology lack an essential functionality compared to CMOS devices. Here, we show that negative differential resistance and large differential gain is possible in a large region of parameter space of the spin torque transistor. We also demonstrate that functionality is preserved when the control part is replaced by a normal metal film with a large spin Hall angle.

Subjects: subject: Differential Geometry (math.DG)

description: In this paper, first we consider that the conformal vector field $\mathbf{X}$ is identical with the Reeb vector field $ς$ and next, assume that $\mathbf{X}$ is pointwise collinear with %the Reeb vector field $ς$, in both cases it is shown that the manifold $\mathbf{N}^{2m+1}$ becomes a Kenmotsu manifold and $\mathbf{N}^{2m+1}$ is locally a warped product $\mathbf{N}' \times_{f} \mathbf{M}^{2m}$, where $\mathbf{M}^{2m}$ is an almost Kähler manifold, $\mathbf{N}'$ is an open interval with coordinate t, and $f = ce^{t}$ for some positive constant c. Beside these, we prove that if a $(\verb"k",\boldsymbolμ)'$-almost Kenmotsu manifold admits a Killing vector field $\mathbf{X}$, then either it is locally a warped product of an almost Kähler manifold and an open interval or $\mathbf{X}$ is a strict infinitesimal contact transformation. Furthermore, we also investigate $\boldsymbolη$-Ricci-Yamabe soliton with conformal vector fields on $(\verb"k",\boldsymbolμ)'$-almost Kenmotsu manifolds and finally, we construct an example.

description: Using cold 87Rb atoms trapped in a 1D-optical lattice, atomic interferometers involving coherent superpositions between different Wannier-Stark atomic states are realized. Two di fferent kinds of trapped interferometer schemes are presented: a Ramsey-type interferometer sensitive both to clock frequency and external forces, and a symmetric accordion-type interferometer, sensitive to external forces only. We evaluate the limits in terms of sensitivity and accuracy of those schemes and discuss their application as force sensors. As a first step, we apply these interferometers to the measurement of the Bloch frequency and the demonstration of a compact gravimeter.

description: We present a new class of exact self-similar solutions possessing cylindrical or spherical symmetry in Born-Infeld theory. A cylindrically symmetric solution describes the propagation of a cylindrical electromagnetic disturbance in a constant background magnetic field in Born-Infeld electrodynamics. We show that this solution corresponds to vacuum breakdown and the subsequent propagation of an electron-positron avalanche. The proposed method of finding exact analytical solutions can be generalized to the model of a spherically symmetric scalar Born-Infeld field in the ($n+1$)-dimensional Minkowski space-time. As an example, the case $n=3$ is discussed.

description: Ameline feels stagnant growing up alongside her quickly maturing friends in their idyllic town. That is, until a half-forgotten goddess approaches her with a proposal: save a city from a curse and gain eternal glory. The only catch is that Ameline cannot truly perform miracles, she must pretend to be a saint in order to protect the city—and Ameline hates lying above all else. Combining conventions of bildungsroman and tragedy, Saint of Rats and Boils follows a young woman’s rise to ambition and those who help or hinder her. Within a world of vengeful gods, living saints, fools, and kings, this young adult novel examines what it means to be renowned instead of being truly known.

description: We are considering a quantum version of the penny flip game, whose implementation is influenced by the environment that causes decoherence of the system. In order to model the decoherence we assume Markovian approximation of open quantum system dynamics. We focus our attention on the phase damping, amplitude damping and amplitude raising channels. Our results show that the Pauli strategy is no longer a Nash equilibrium under decoherence. We attempt to optimize the players' control pulses in the aforementioned setup to allow them to achieve higher probability of winning the game compared to the Pauli strategy.

description: New observables with which we can study the two-nucleon weak interactions at low energies are considered. In the breakup of the deuteron by photons, polarization of outgoing neutrons can depend on the parity-violating component of two-nucleon interactions. We express the parity-violating polarization in general forms, and perform numerical calculations with a pionless effective field theory. The theory has unknown parity-violating low energy constants, and the results are expressed in linear combination of them. We discuss the results and their implication to the understanding of the hadronic weak interactions.

description: Some new physics models, such as "beautiful mirrors" scenario, predict the existence of the bottom partner $B'$. Considering the constraints from the data for the $Z\rightarrow b\bar{b}$ branching ratio $R_{b}$ and the $FB$ asymmetry $A_{FB}^{b}$ on the relevant free parameters, we calculate the contributions of $B'$ to the cross section $σ(Zb)$ and the $Z$ polarization asymmetry $A_{Z}$ for $Zb$ production at the $LHC$. We find that the bottom partner $B'$ can generate significant corrections to $σ(Zb)$ and $A_{Z}$, which might be detected in near future.

description: This thesis explores the use of language, myth creation, and the development of American civil religion to construct a national identity. It analyzes the role of religious language in imagining an identity for the American people, with Protestant Christianity being a driving force for this rhetoric. Throughout this thesis, I argue that specific historical figures have become symbols of American identity, creating an American cult that venerates these figures as sacred icons. This thesis traces the historical development of thought as it relates to American political figures taking on mythical and legendary status in the minds of the citizens. The role of monuments and memorials in Washington, D.C., as capsules into the past and symbolic representations of what is essential to the American people, is also explored. I argue that monuments and memorials have artistic perspectives and use specific imagery that shows how the designers want their audience to view and interpret the events and people who are the subject of the piece and how notions of national identity are projected onto monuments, memorials, and symbols. The thesis also examines the growing phenomenon of far-right nationalism in the United States and how President Trump used populism and rhetoric of American civil religion to strengthen his support. I also explore the variations of patriotic participation through protests by Colin Kaepernick and the Black Lives Matter Movement showing the diverse nature of national identity and civic contribution. The thesis also delves into the importance of the military in the United States and how soldiers have become a symbol of American patriotism and identity. By highlighting the role of religion, language, and mythology in shaping national identity, this thesis sheds light on the complex interplay between culture, history, and identity in the United States.

We also investigate spin polarization on the surface of a topological insulator induced by a circularly polarized light and refraction at the junction between two topological insulators. As for spincaloritronics effects, we show transverse magnetic heat transport and thermoelectric transport in topological insulators. Finite-size effect in topological insulators and band structure engineering of interface states of topological insulators are also discussed.

Creators: name: Lukas, Paul

Publisher: name: Senckenberg Gesellschaft für Naturforschung

description: The jaws of anuran tadpoles consist of several evolutionary novelties, which are unique within the vertebrates. The most noticeable of these novelties are two cartilaginous elements called rostralia and the derived organisation of cranial muscles, which form an entirely new feeding apparatus. The suprarostral cartilage is located in the upper and the infrarostral cartilages in the lower jaw. Between infrarostral and Meckel’s cartilage an intramandibular joint is present. The morphological diversity of anuran tadpoles and their different feeding modes could be associated with these cartilaginous innovations and the shifted insertions of various cranial muscles. The evolutionary origin of the rostralia and, more generally, of evolutionary novelties remains unclear most widely. Therefore, we investigated the molecular basis of the morphogenesis of the infrarostrals by functional knock-down of the bagpipe-related homeobox gene zampogna (zax) in Xenopus laevis. Its knockdown caused fatal deformation of the anterior part of the head and disappearance of the infrarostrals as well as shifted muscular insertions. Higher doses caused a total loss of head structures including mouth, eyes and cranial cartilages. Using quantitative PCR, we found a correlation between cartilage formation and the expression of zax. Our findings indicate that zax is part of a regulatory gene network controlling the development of the ventral part of the anuran head and the formation of the intramandibular joint. This supports the view that not the infrarostrals but rather the intramandibular joint, which forms in a zax-dependent manner, is the actual evolutionary novelty.

description: We investigate the possibility that the primordial perturbation has two sources: the inflaton and a spectator field, which is not dynamically important during inflation but which after inflation can contribute to the curvature perturbation. The recent Planck results on the power spectrum and non-Gaussianity allow us to put constraints on such mixed models. In the generic case, where no specific model for the inflaton or the spectator is assumed, one finds that in the mixed scenario it is possible to have a large trispectrum with tau_NL >> (f_NL)^2. The constraints on inflation models in the plane of the spectral index and tensor-to-scalar ratio are modified by the presence of a spectator and depend also on the ratio of the spectator-to-inflaton power R. If one chooses the spectator to be the curvaton with a quadratic potential, non-Gaussianities can be computed and imply restrictions on possible values of R. We also consider a mixed curvaton and chaotic inflation model and show that even quartic chaotic inflation is still feasible in the context of mixed models.

description: Ultrasensitive detection of methane, isotopic carbon dioxide, carbon monoxide, formaldehyde, acetylene and ethylene is performed in the spectral range 2.5 - 5 μm using intracavity spectroscopy in broadband optical parametric oscillators (OPOs). The OPOs were operated near degeneracy and synchronously pumped either by a mode-locked erbium (1560 nm) or thulium (2050 nm) fiber laser. A large instantaneous bandwidth of up to 800 cm$^{-1}$ allows for simultaneous detection of several gases. We observe an effective path length enhancement due to coherent interaction inside the OPO cavity and achieve part-per-billion sensitivity levels. The measured spectral shapes are in good agreement with a model that takes into account group delay dispersion across the broad OPO frequency band.

description: It is shown that the two complex Cartesian components of the electric field of a monochromatic electromagnetic plane wave, with a temporal and spatial dependence of the form ${\rm e}^{{\rm i} (kz - ωt)}$, form a SU(2) spinor that corresponds to a tangent vector to the Poincaré sphere representing the state of polarization and phase of the wave. The geometrical representation on the Poincaré sphere of the effect of some optical filters is reviewed. It is also shown that in the case of a partially polarized beam, the coherency matrix defines two diametrically opposite points of the Poincaré sphere.

Comptonization efficiencies of the variability classes of GRS 1915+105

description: The Galactic microquasar GRS 1915+105 exhibits at least seventeen types of variability classes. Intra and inter class transitions are reported to be observed within seconds to hours. Since the observation was not continuous, these classes appeared to be exhibited in a random order. Our goal is to predict a sequence of these classes. In this paper, we compute the ratio of the photon counts obtained from the power-law component and the blackbody component of each class and call this ratio as the `Comptonizing efficiency' (CE) of that class. We sequence the classes in the ascending order of CE and find that this sequence matches with a few class transitions observed by RXTE satellite and IXAE instruments on board IRS-P3. A change in CE corresponds to a change in the optical depth of the Compton cloud. Our result implies that the optical depth of the Compton cloud gradually rises as the variability class becomes harder.

On finite-dimensional attractors of homeomorphisms
Creators: name: Robinson, James C.
name: Sanchez-Gabites, Jaime J.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Dynamical Systems (math.DS)

description: Let $E$ be a linear space and suppose that $A$ is the global attractor of either (i) a homeomorphism $F:E\rightarrow E$ or (ii) a semigroup $S(\cdot)$ on $E$ that is injective on $A$. In both cases $A$ has trivial shape, and the dynamics on $A$ can be described by a homeomorphism $F:A\rightarrow A$ (in the second case we set $F=S(t)$ for some $t>0$). If the topological dimension of $A$ is finite we show that for any $ε>0$ there is an embedding $e:A\rightarrow{\mathbb R}^k$, with $k\sim{\rm dim}(A)$, and a (dynamical) homeomorphism $f:\R^k\rightarrow\R^k$ such that $F$ is conjugate to $f$ on $A$ (i.e.\ $F|_A=e^{-1}\circ f\circ e$) and $f$ has an attractor $A_f$ with $e(A)\subset A_f\subset N(e(A),ε)$. In other words, we show that the dynamics on $A$ is essentially finite-dimensional. We characterise subsets of ${\mathbb R}^n$ that can be the attractors of homeomorphisms as cellular sets, give elementary proofs of various topological results connected to Borsuk's theory of shape and cellularity in Euclidean spaces, and prove a controlled homeomorphism extension theorem.

title: Evaluating Costs Associated with Management Decisions of Replacement Dairy Heifers and Their Impact on the Total Rearing Investment
Creators: name: Hawkins, Anna
Publisher: name: University of Kentucky Libraries
Year: 2019

description: Replacement heifer rearing is critical for the future of the dairy operation, especially to improve genetic merit and maintain herd size. A replacement heifer from the day she is born to the day she calves herself is generally a 2-year investment without potential income. A myriad of options exists on how to manage, fed, and ultimately raise replacement heifers. This study quantifies the costs associated with replacement heifer management decisions from birth to calving related to housing, labor, feed and health. The heifer rearing period can be broken into pre and post weaning sections to allow for more understanding the variation of these different biological time periods. Variation can influence the investment per day and breakdown of resources required from a dairy producer. Total heifer raising cost varied broadly across all management scenarios in our study, with feed and labor consistently representing over 60% of the total cost. After determining the true cost on an individual farm, or providing developed assumed cost for a change in management, producers can better manage current expenses and be more prepared for future investment.

Partial dynamical symmetry as a selection criterion for many-body interactions

description: We propose the use of partial dynamical symmetry (PDS) as a selection criterion for higher-order terms in situations when a prescribed symmetry is obeyed by some states and is strongly broken in others. The procedure is demonstrated in a first systematic classification of many-body interactions with SU(3) PDS that can improve the description of deformed nuclei. As an example, the triaxial features of the nucleus 156Gd are analyzed.

Adaptive machine and its thermodynamic costs

description: We study the minimal thermodynamically consistent model for an adaptive machine that transfers particles from a higher chemical potential reservoir to a lower one. This model describes essentials of the inhomogeneous catalysis. It is supposed to function with the maximal current under uncertain chemical potentials: if they change, the machine tunes its own structure fitting it to the maximal current under new conditions. This adaptation is possible under two limitations. (i) The degree of freedom that controls the machine's structure has to have a stored energy (described via a negative temperature). The origin of this result is traced back to the Le Chatelier principle. (ii) The machine has to malfunction at a constant environment due to structural fluctuations, whose relative magnitude is controlled solely by the stored energy. We argue that several features of the adaptive machine are similar to those of living organisms (energy storage, aging).
