description: This work originates from part of a final year undergraduate research project on the Eisenhart lift for Hamiltonian systems. The Eisenhart lift is a procedure to describe trajectories of a classical natural Hamiltonian system as geodesics in an enlarged space. We point out that it can be easily obtained from basic principles of Hamiltonian dynamics, and as such it represents a useful didactical way to introduce graduate students to several modern concepts of geometry applied to physics: curved spaces, both Riemannian and Lorentzian, conformal transformations, geometrisation of interactions and extra dimensions, geometrisation of dynamical symmetries. For all these concepts the Eisenhart lift can be used as a theoretical tool that provides easily achievable examples, with the added benefit of also being a topic of current research with several applications, among which the study of dynamical systems and non-relativistic holography.

description: Contextuality is a phenomenon at the heart of the quantum mechanical departure from classical behaviour, and has been recently identified as a resource in quantum computation. Experimental demonstration of contextuality is thus an important goal. The traditional form of contextuality -- as violation of a Kochen-Specker inequality -- requires a quantum system with at least three levels, and the status of the assumption of determinism used in deriving those inequalities has been controversial. By considering `unsharp' observables, Liang, Spekkens and Wiseman (LSW) derived an inequality for generalized noncontextual models that doesn't assume determinism, and applies already to a qubit. We experimentally implement the LSW test using the polarization states of a heralded single photon and three unsharp binary measurements. We violate the LSW inequality by more than 16 standard deviations, thus showing that our results cannot be reproduced by a noncontextual subset of quantum theory.

Unified design method of time delayed PI controller for first order plus dead-time process models with different dead-time to time constant ratio
Creators: name: T, Jarin
Publisher: name: figshare
Year: 2023
Subjects: Electrical engineering not elsewhere classified

description: The time delay element present in the PI controller brings dead-time compensation capability and shows improved performance for dead-time processes. However, design of robust time delayed PI controller needs much responsiveness for uncertainty in dead-time processes. Hence in this paper, robustness of time delayed PI controller has been analyzed for First Order plus Dead-Time (FOPDT) process model. The process having dead-time greater than three times of time constant is very sensitive to dead-time variation. A first order filter is introduced to ensure robustness. Furthermore, integral time constant of time delayed PI controller is modified to attain better regulatory performance for the lag-dominant processes. The FOPDT process models are classified into dead-time/lag dominated on the basis of dead-time to time constant ratio. A unified tuning method is developed for processes with a number of dead-time to time constant ratio. Several simulation examples and experimental evaluation are exhibited to show the efficiency of the proposed unified tuning technique. The applicability to the process models other than FOPDT such as high-order, integrating, right half plane zero systems are also demonstrated via simulation examples.

A polynomial-time algorithm to find shortest paths with recourse
Creators: name: Provan, J. Scott
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: The Shortest Path with Recourse Problem involves finding the shortest expected-length paths in a directed network each of whose arcs have stochastic traversal lengths (or delays) that become known only upon arrival at the tail of that arc. The traveler starts at a given source node, and makes routing decisions at each node in such a way that the expected distance to a given sink node is minimized. We develop an extension of Dijkstra’s algorithm to solve the version of the problem where arclengths are nonnegative and reset after each arc traversal. All known no-reset versions of the problem are NP-hard. We make a partial extension to the case where negative arclengths are present.

description: A parent's ability to be autonomy supportive, specifically when communicating with their adolescent about romantic relationships and sex, is critical to promote healthy adolescent development. Previous research examining parent-adolescent communication about sex and romantic relationships has relied heavily on self-report methods, specifically from adolescents. However, this approach does not adequately capture the interdependent nature of the parent-adolescent relationship or the way they have conversations about sex and romantic relationships. In this study, 50 parent-adolescent dyads were observed having discussions about music media. Participants watched three popular music videos which contained messages of positive romantic relationships, overt sexualization, or violence in romantic relationships. Participants were asked to discuss the three videos together where they were audio and video recorded in a comfortable laboratory setting as they watched each video. The recordings were then coded for the types of questions asked during the discussion which were related to autonomy supportive behaviors. The data were modeled after the Actor-Partner Interdependence Model and subsequently analyzed using structural equation modeling. Results indicated that parents who reported higher autonomy granting in their daily life asked significantly more clarifying and redirecting questions of their adolescent during the discussions about music media. Results also indicated that when adolescents reported that their parents were high in autonomy granting overall, they had parents who were less likely to ask both redirecting questions and clarifying questions.
Tidal synchronization of close-in satellites and exoplanets. II. Spin dynamics and extension to Mercury and exoplanets host stars

description: This paper deals with the application of the creep tide theory (Ferraz-Mello, CeMDA 116, 109, 2013) to the rotation of close-in satellites, Mercury, close-in exoplanets and their host stars. The solutions show two extreme cases: close-in giant gaseous planets, with fast relaxation (low viscosity) and satellites and Earth-like planets, with slow relaxation (high viscosity). The rotation of close-in gaseous planets follows the classical Darwinian pattern: it is tidally driven towards a stationary solution which is synchronized, but, if the orbit is elliptical, with a frequency larger than the orbital mean-motion. The rotation of rocky bodies, however, may be driven to several attractors whose frequencies are 1/2,1,3/2,2,5/2 ... times the mean-motion. The number of attractors increases with the viscosity of the body and with the orbital eccentricity. The classical example is Mercury, whose rotational period is 2/3 of the orbital period (3/2 attractor). The planet behaves as a molten body with a relaxation that allowed it to cross the 2/1 attractor without being trapped, but not to escape being trapped in the 3/2 one. In that case, the relaxation is estimated to lie in the interval 4.6 -- 27 x 10^{-9} s^{-1} (equivalent to a quality factor roughly constrained to the interval 5

description: We introduce and analyze several variants of a system of differential equations which model the dynamics of social outbursts, such as riots. The systems involve the coupling of an explicit variable representing the intensity of rioting activity and an underlying (implicit) fi eld of social tension. Our models include the effects of exogenous and endogenous factors as well as various propagation mechanisms. From numerical and mathematical analysis of these models we show that the assumptions made on how different locations infl uence one another and how the tension in the system disperses play a major role on the qualitative behavior of bursts of social unrest. Furthermore, we analyze here various properties of these systems, such as the existence of traveling wave solutions, and formulate some new open mathematical problems which arise from our work.

The Singular Structure and Regularity of Stationary and Minimizing Varifolds

description: If one considers an integral varifold $I^m\subseteq M$ with bounded mean curvature, and if $S^k(I)\equiv\{x\in M: \text{ no tangent cone at $x$ is }k+1\text{-symmetric}\}$ is the standard stratification of the singular set, then it is well known that $\dim S^k\leq k$. In complete generality nothing else is known about the singular sets $S^k(I)$. In this paper we prove for a general integral varifold with bounded mean curvature, in particular a stationary varifold, that every stratum $S^k(I)$ is $k$-rectifiable. In fact, we prove for $k$-a.e. point $x\in S^k$ that there exists a unique $k$-plane $V^k$ such that every tangent cone at $x$ is of the form $V\times C$ for some cone $C$. In the case of minimizing hypersurfaces $I^{n-1}\subseteq M^n$ we can go further. Indeed, we can show that the singular set $S(I)$, which is known to satisfy $\dim S(I)\leq n-8$, is in fact $n-8$ rectifiable with uniformly finite $n-8$ measure. An effective version of this allows us to prove that the second fundamental form $A$ has apriori estimates in $L^7_{weak}$ on $I$, an estimate which is sharp as $|A|$ is not in $L^7$ for the Simons cone. In fact, we prove the much stronger estimate that the regularity scale $r_I$ has $L^7_{weak}$-estimates. The above results are in fact just applications of a new class of estimates we prove on the quantitative stratifications $S^k_{ε,r}$ and $S^k_ε\equiv S^k_{ε,0}$. Roughly, $x\in S^k_ε\subseteq I$ if no ball $B_r(x)$ is $ε$-close to being $k+1$-symmetric. We show that $S^k_ε$ is $k$-rectifiable and satisfies the Minkowski estimate $Vol(B_r\,S_ε^k)\leq C_εr^{n-k}$. The proof requires a new $L^2$-subspace approximation theorem for integral varifolds with bounded mean curvature, and a $W^{1,p}$-Reifenberg type theorem proved by the authors in \cite{NaVa+}.

description: Background and Objective: The stroke center at the New Jersey Neuroscience Institute is located in Edison township in New Jersey which has one of the largest fractions of Asian immigrants in USA. This study aims to compare risk factors and etiology of ischemic stroke in patients of Indian origin with those of the White-Americans. Methods: Information pertaining to stroke risk factors was prospectively collected between July 2005 to June 2008. The patients underwent a stroke work-up, which included computerized tomograms, magnetic resonance imaging and magnetic resonance angiography of brain, carotid duplex, Holter monitoring and two dimensional echocardiogram. Etiology of ischemic stroke was ascertained using the classification developed for the Trial of Org 10172 in Acute Stroke Treatment (TOAST). Results: The data of 378 patients (mean age = 71±12 years, 54% females, White-Americans=347) with ischemic stroke were collected over 3 years. The 31 Indian patients (mean age = 64±10 years) had a higher proportion of diabetics mellitus (p=0.001) and were signifi cantly younger than the White-Americans. There were signifi cantly lower proportion of persons who smoked (p=0.03) or used alcohol (p=0.03). The commonest cause of ischemic stroke was small vessel occlusive disease, rather than large artery atherosclerosis among the White-Americans (p=0.009). Conclusions: when compared to White-Americans, The Indian-American developed stroke at a younger age, despite a lower rate of alcohol and tobacco use. They have a higher prevalence of diabetes and physical inactivity. The commonest cause of ischemic stroke was small vessel occlusive disease.

description: The relationship between cytosolic Ca2+ and catecholamine secretion during stimulus-secretion coupling has been examined at individual chromaffin cells isolated from the cow and rat. Vesicular catecholamine exocytosis was determined via amperometric measurements with carbon fiber microelectrodes and fura-2 was used for simultaneous fluorescent monitoring of cytosolic Ca2+ at the same cell.12 Individual secretory vesicles in cells from the two species were found to release similar amounts of catecholamine. In addition, the time courses for secretion from individual vesicles was similar with rat and bovine chromaffin cells. The total quantity of catecholamine released and the change in cytosolic Ca2+ were also similar in response to exposure to K+ (60 mM), DMPP (50 uM), and histamine (50 uM), although both responses were more prolonged following DMPP and histamine at bovine cells. Agents that mobilize intracellular Ca2+-stores such as methacholine, caffeine and bradykinin resulted in different cytosolic Ca2+ and exocytosis responses at the rat and bovine chromaffin cells. Results indicates a heightened Ca2+ store activity or a more filled state in chromaffin cells from the rat. The results of this study clearly show that single cell techniques can be used to characterize stimulus-secretion coupling. The requirement for lower numbers of cells with these techniques means that chromaffin cells from rodents can be routinely employed. This can be advantageous to minimize biological variability21 which occurs with organs obtained from slaughter houses and enables the investigation of genetically-altered animals.

description: Classical variational principles can be deduced from quantum variational principles via formal reparameterization of the latter. It is shown that such reparameterization is possible without invoking any assumptions other than classicality and without appealing to dynamical equations. As examples, first principle variational formulations of classical point-particle and cold-fluid motion are derived from their quantum counterparts for Schrodinger, Pauli, and Klein-Gordon particles.

description: We show that every semialgebraic set admits a semialgebraic triangulation such that each closed simplex is $C^1$ differentiable. As an application, we give a straightforward definition of the integration $\int_X ω$ over a compact semialgebraic subset $X$ of a differential form $ω$ on an ambient algebraic manifold, that provides a significant simplification of the theory of semialgebraic singular chains and integrations. Our results hold over every (possibly non-archimedian) real closed field.

Orbital-motion-limited theory of dust charging and plasma response
Creators: name: Tang, Xian-Zhu
name: Delzanno, Gian Luca
Publisher: name: arXiv
Year: 2015
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: The foundational theory for dusty plasmas is the dust charging theory that provides the dust potential and charge arising from the dust interaction with a plasma. The most widely used dust charging theory for negatively charged dust particles is the so-called orbital motion limited (OML) theory, which predicts the dust potential and heat collection accurately for a variety of applications, but was previously found to be incapable of evaluating the dust charge and plasma response in any situation. Here we report a revised OML formulation that is able to predict the plasma response and hence the dust charge. Numerical solutions of the new OML model show that the widely-used Whipple approximation of dust charge-potential relationship agrees with OML theory in the limit of small dust radius compared with plasma Debye length, but incurs large (order-unity) deviation from the OML prediction when the dust size becomes comparable with or larger than plasma Debye length. This latter case is expected for the important application of dust particles in a tokamak plasma.

The sensitivity of nucleosynthesis in Type I X-ray bursts to thermonuclear reaction-rate variations

description: We examine the sensitivity of nucleosynthesis in Type I X-ray bursts to variations in nuclear rates. As a large number of nuclear processes are involved in these phenomena -with the vast majority of reaction rates only determined theoretically due to the lack of any experimental information- our results can provide a means for determining which rates play significant roles in the thermonuclear runaway. These results may then motivate new experiments. For our studies, we have performed a comprehensive series of one-zone post-processing calculations in conjunction with various representative X-ray burst thermodynamic histories. We present those reactions whose rate variations have the largest effects on yields in our studies.
