Transport of Brownian particles in a narrow, slowly-varying serpentine channel

description: We study the transport of Brownian particles under a constant driving force and moving in channels that present a varying centerline but have constant aperture width. We investigate two types of channels, {\it solid} channels in which the particles are geometrically confined between walls and {\em soft} channels in which the particles are confined by a periodic potential. We consider the limit of narrow, slowly-varying channels, i.e., when the aperture and the variation in the position of the centerline are small compared to the length of a unit cell in the channel (wavelength). We use the method of asymptotic expansions to determine both the average velocity (or mobility) and the effective diffusion coefficient of the particles. We show that both solid and soft-channels have the same effects on the transport properties up to $O(ε^2)$. We also show that the mobility in a solid-channel at $O(ε^4)$ is smaller than that in a soft-channel. Interestingly, in both cases, the corrections to the mobility of the particles are independent of the Péclet number and, as a result, the Einstein-Smoluchowski relation is satisfied. Finally, we show that by increasing the solid-channel width from $w(x)$ to $\sqrt{6/π}w(x)$, the mobility of the particles in the solid-channel can be matched to that in the soft-channel up to $O(ε^4)$.

description: Bangladesh is underlain by shallow aquifers in which millions of drinking water wells are emplaced without annular seals. Fecal contamination has been widely detected in private tubewells. To evaluate the impact of well construction on microbial water quality 35 private tubewells (11 with intact cement platforms, 19 without) and 17 monitoring wells (11 with the annulus sealed with cement, 6 unsealed) were monitored for cultured E. coli over 18 months. Additionally, two “snap shot” sampling events were performed on a subset of wells during late-dry and early-wet seasons, wherein the fecal indicator bacteria (FIB) E. coli, Bacteroidales and the pathogenicity genes eltA (ETEC E. coli), ipaH (Shigella) and 40/41 hexon (adenovirus) were detected using qPCR. No difference in E. coli detection frequency was found between tubewells with and without platforms. Unsealed private wells, however, contained cultured E. coli more frequently and higher concentrations of FIB than sealed monitoring wells (p<0.05), suggestive of rapid downward flow along unsealed annuli. As a group the pathogens ETEC, Shigella and adenovirus were detected more frequently (10/22) during the wet season than the dry season (2/20). This suggests proper sealing of private tubewell annuli may lead to substantial improvements in microbial drinking water quality.

description: Several models compete to explain the abundance properties of stellar populations in globular clusters. One of the main constraints is the present-day ratio of first- and second-generation stars that are currently identified based on their sodium content. We propose an alternative interpretation of the observed sodium distribution, and suggest that stars with low sodium abundance that are counted as members of the first stellar generation could actually be second-generation stars. We compute the number ratio of second-generation stars along the Na distribution following the fast rotating massive star model using the same constraints from the well-documented case of NGC 6752 as in our previous developments. We reproduce the typical percentage of low-sodium stars usually classified as first-generation stars by invoking only secondary star formation from material ejected by massive stars and mixed with original globular cluster material in proportions that account for the Li-Na anti-correlation in this cluster. Globular clusters could be totally devoid of first-generation low-mass stars today. This can be tested with the determination of the carbon isotopic ratio and nitrogen abundance in turn-off globular cluster stars. Consequences and related issues are briefly discussed.

description: We apply the proper orthogonal decomposition (POD) to the nonlinear Schrödinger (NLS) equation to derive a reduced order model. The NLS equation is discretized in space by finite differences and is solved in time by structure preserving symplectic mid-point rule. A priori error estimates are derived for the POD reduced dynamical system. Numerical results for one and two dimensional NLS equations, coupled NLS equation with soliton solutions show that the low-dimensional approximations obtained by POD reproduce very well the characteristic dynamics of the system, such as preservation of energy and the solutions.

description: Using the data of the Baltimore Hip Study 5 (a home-based exercise intervention), this study examined how social support for exercise by experts (SSE-E) affected the self-efficacy, outcome expectations, and exercise behavior among older women following a hip fracture. The total sample included 164 females aged 65 years (M = 81.0; SD = 6.9) who had surgical repair of a non-pathologic hip fracture. Model testing showed a direct relationship between SSE-E and outcome expectations for exercise. There was, however, no direct or indirect relationship between SSE-E and self-efficacy or exercise behavior. The positive effect of SSE-E on the outcome expectations for exercise in older women recovering from a hip fracture provides an opportunity for health care providers in improving physical activity in this population.

description: In this study, we explore the ratchet effect in graphene with artificial, triangular scatterers from a theoretical standpoint. It is demonstrated that the skew scattering of carriers by such coherently oriented defects results in the ratchet effect in graphene, i.e., in a direct current under the action of an oscillating electric field. Scattering on various types of defects exhibiting threefold symmetry is considered in this paper: scattering on a cluster in the shape of a solid triangle in the classical and quantum mechanical limits, and scattering on three- point defects placed at the corners of a triangle. The DC current is calculated for a classical range of oscillating field frequencies.

description: The SuMIRe Prime Focus Spectrograph (PFS), developed for the 8-m class SUBARU telescope, will consist of four identical spectrographs, each receiving 600 fibers from a 2394 fiber robotic positioner at the telescope prime focus. Each spectrograph includes three spectral channels to cover the wavelength range 0.38-1.26 um with a resolving power ranging between 2000 and 4000. A medium resolution mode is also implemented to reach a resolving power of 5000 at 0.8 um. Each spectrograph is made of 4 optical units: the entrance unit which produces three corrected collimated beams and three camera units (one per spectral channel). The beam is split by using two large dichroics; and in each arm, the light is dispersed by large VPH gratings. The proposed optical design was optimized to achieve the requested image quality while simplifying the manufacturing of the whole optical system. The camera design consists in an innovative Schmidt camera observing a large field-of-view (10 degrees) with a very fast beam. To achieve such a performance, the classical spherical mirror is replaced by a catadioptric mirror (i.e meniscus lens with a reflective surface on the rear side of the glass, like a Mangin mirror). This article focuses on the optical architecture of the PFS spectrograph and the perfornance achieved. We will first described the global optical design of the spectrograph. Then, we will focus on the Mangin-Schmidt camera design. The analysis of the optical performance and the results obtained are presented in the last section.

description: A new tetracopper(II) coordination compound, [Cu4Cl6O(iQuin)4] (1, iQuin = isoquinoline), with an adamantane-like structure is reported. The compound crystallizes in the tetragonal space group P4/n with one crystallographically unique Cu(II) and oxide ions, and two chloride ions. Variable temperature magnetic measurements reveal dominant antiferromagnetic interactions, but the crystal structure suggests the likelihood of magnetic frustration in the compound. Modeling results indicate the presence of two competing interactions, Jap/kB=−61.1(7) K and Jeq/kB=41.2(3) K (ap = apical; eq = equatorial), as well as a Zeeman coupling of the Cu(II) ions with the external magnetic field. All data were fit using the Hamiltonian H^=J1∑i=16S^γi(1)⋅S^γ2(2)+J2∑i=16(S^αi(1)⋅S^αi(2)+S^βi(1)+S^βi(2))+gμBH→⋅∑j=14S^j

description: This study characterizes the profile of women (N = 1,789) ages 50 and over who report body size satisfaction on a figure rating scale. Satisfied women (12.2%) had a lower body mass index and reported fewer eating disorder symptoms, dieting behaviors, and weight and appearance dissatisfaction. Interestingly, satisfied women exercised more than dissatisfied women and weight and shape still played a primary role in their self-evaluation. Weight monitoring and appearance altering behaviors did not differ between groups. Body satisfaction was associated with better overall functioning. This end point appears to represent effortful body satisfaction rather than passive contentment.

description: Time-domain Brillouin scattering technique, also known as picosecond ultrasonic interferometry, which provides opportunity to monitor propagation of nanometers to sub-micrometers length coherent acoustic pulses in the samples of sub-micrometers to tens of micrometers dimensions, was applied to depth-profiling of polycrystalline aggregate of ice compressed in a diamond anvil cell to Megabar pressures. The technique allowed examination of characteristic dimensions of elastic inhomogeneities and texturing of polycrystalline ice in the direction normal to the diamond anvil surfaces with sub-micrometer spatial resolution via time-resolved measurements of variations in the propagation velocity of the acoustic pulse traveling in the compressed sample. The achieved two-dimensional imaging of the polycrystalline ice aggregate in-depth and in one of the lateral directions indicates the feasibility of three-dimensional imaging and quantitative characterization of acoustical, optical and acousto-optical properties of transparent polycrystalline aggregates in diamond anvil cell with tens of nanometers in-depth resolution and lateral spatial resolution controlled by pump laser pulses focusing.

description: We explain spin structure for a spin-one hadron, in which there are new structure functions, in addition to the ones ($F_1$, $F_2$, $g_1$, $g_2$) which exist for the spin-1/2 nucleon, associated with its tensor structure. The new structure functions are $b_1$, $b_2$, $b_3$, and $b_4$ in deep inelastic scattering of a charged-lepton from a spin-one hadron such as the deuteron. Among them, twist-two functions are related by the Callan-Gross type relation $b_2 = 2 x b_1$ in the Bjorken scaling limit. First, these new structure functions are introduced, and useful formulae are derived for projection operators of $b_{1-4}$ from a hadron tensor $W_{μν}$. Second, a sum rule is explained for $b_1$, and possible tensor-polarized distributions are discussed by using HERMES data in order to propose future experimental measurements and to compare them with theoretical models. A proposal was approved to measure $b_1$ at the Thomas Jefferson National Accelerator Facility (JLab), so that much progress is expected for $b_1$ in the near future. Third, formalisms of polarized proton-deuteron Drell-Yan processes are explained for probing especially tensor-polarized antiquark distributions, which were suggested by the HERMES data. The studies of the tensor-polarized structure functions will open a new era in 2020's for tensor-structure studies in terms of quark and gluon degrees of freedom, which is much different from ordinary descriptions in terms of nucleons and mesons.

description: Given a graph $H$, a graph $G$ is called $H$-critical if $G$ does not admit a homomorphism to $H$, but any proper subgraph of $G$ does. Observe that $K_{k-1}$-critical graphs are the standard $k$-(colour)-critical graphs. We consider questions of extremal nature previously studied for $k$-critical graphs and generalize them to $H$-critical graphs. After complete graphs, the next natural case to consider for $H$ is that of the odd-cycles. Thus, given integers $\ell$ and $k$, $\ell\geq k$, we ask: what is the smallest order of a $C_{2\ell +1}$-critical graph of odd-girth at least $2k+1$? Denoting this value by $η(k,C_{2\ell+1})$, we show that $η(k,C_{2\ell+1})=4k$ for $1\leq\ell\leq k\leq\frac{3\ell+i-3}{2}$ ($2k=i\bmod 3$) and that $η(3,C_5)=15$. The latter means that a smallest graph of odd-girth~$7$ not admitting a homomorphism to the $5$-cycle is of order~$15$. Computational work shows that there are exactly eleven such graphs on $15$~vertices of which only two are $C_5$-critical.

description: Since the nineteen-seventies public history has emerged as an increasingly coherent discipline in North America, Australia, New Zealand, the U.K. and, latterly, in a wider European context. In all of these places it has had a connected but distinctly different gestation, and the nature of how history is applied, constructed, proffered or sold for public consumption is unique to each society. In Ireland, and within the history profession connected to it, its meaning is yet to be fully explored. Recent talks, symposia and conferences have established the term in the public imagination. As it is presently conceived public history in Ireland either relates specifically to commemorative events and the effect historians might have on official discourse relating to them, or to a series of controversial and contested historiographical debates. This article, by contrast, seeks a wider, more inclusive definition that includes the ‘public’ as an actor in it.

description: The main goal of the present paper is the construction of twisted generalized differential cohomology theories and the comprehensive statement of its basic functorial properties. Technically it combines the homotopy theoretic approach to (untwisted) generalized differential cohomology developed by Hopkins-Singer and later by the first author and D. Gepner with the oo-categorical treatement of twisted cohomology by Ando-Blumberg-Gepner. We introduce the notion of a differential twist for a given generalized cohomology theory and construct twisted differential cohomology groups (resp. spectra). The main technical results of the paper are existence and uniqueness statements for differential twists. These results will be applied in a variety of examples, including K-theory, topological modular forms and other cohomology theories.

description: A famous theorem of Weyl states that if $M$ is a compact submanifold of euclidean space, then the volumes of small tubes about $M$ are given by a polynomial in the radius $r$, with coefficients that are expressible as integrals of certain scalar invariants of the curvature tensor of $M$ with respect to the induced metric. It is natural to interpret this phenomenon in terms of curvature measures and smooth valuations, in the sense of Alesker, canonically associated to the Riemannian structure of $M$. This perspective yields a fundamental new structure in Riemannian geometry, in the form of a certain abstract module over the polynomial algebra $\mathbb R[t]$ that reflects the behavior of Alesker multiplication. This module encodes a key piece of the array of kinematic formulas of any Riemannian manifold on which a group of isometries acts transitively on the sphere bundle. We illustrate this principle in precise terms in the case where $M$ is a complex space form.

description: Il presente lavoro ha come focus la convergenza tra lo studio del linguaggio e il campo delle Neuroscienze. Nello specifico, la cornice concettuale di questo lavoro affonda le proprie radici nell’approccio analitico-comportamentale. Il principale scopo del lavoro è quello di combinare i differenti usi funzionali del linguaggio con le tecnologie proprie delle Neuroscienze, in particolare del Neuroimaging, creando così una disciplina capace di raccogliere l’eredità lasciataci da Skinner, relativa al trattamento dei comportamenti “covert” (privati), al pari di quelli “overt” (pubblici). Gli strumenti forniti dal mondo delle Neuroscienze e i loro continui avanzamenti possono adesso finalmente incontrare le aspettative di Skinner. I dati presentati nel mio lavoro possono aprire nuove prospettive di insegnamento e suggerire possibili procedure di insegnamento di abilità verbali a pazienti con disabilità cognitiva o disturbi dell’apprendimento e così trasferire queste nuove modalità di insegnamento alla “terapia” di altri tipi di deficit, al di là di quelli linguistici. [a cura dell'Autore]
description: The present work deals with the convergence between the study of human language and the field of neurosciences. In particular, its conceptual framework is rooted in the behavior analytic approach. Its first and main aim is to try to combine the different functional uses of language with the technologies of the neurosciences, particularly neuroimaging. The basic idea is to create a discipline capable to follow Skinner’s lead in treating covert behavior just like the overt one. The continuous advancement and tools provided by neuroscience can now match Skinner’s expectations. In fact, the data presented in this thesis can open to new teaching perspectives and suggest possible strategies to both overcome language difficulties in subject with cognitive disabilities and transfer these new learning technologies to other kinds of impairments.

description: Recently, it has been argued that various measures of SUSY naturalness-- electroweak, Higgs mass and EENZ/BG-- when applied consistently concur with one another and make very specific predictions for natural supersymmetric spectra. Highly natural spectra are characterized by light higgsinos with mass not too far from m_h and well-mixed but TeV-scale third generation squarks. We apply the unified naturalness measure to the case of heavy Higgs bosons A, H and H^\pm. We find that their masses are bounded from above by naturalness depending on tan(beta): e.g. for 10% fine-tuning and tan(beta)~ 10, we expect m_A< 2.5 TeV whilst for 3% fine-tuning and tan(beta) as high as 50, then m_A< 8 TeV. Furthermore, the presence of light higgsinos seriously alters the heavy Higgs boson branching ratios, thus diminishing prospects for usual searches into Standard Model (SM) final states, while new discovery possibilities arise due to the supersymmetric decay modes. The heavy SUSY decay modes tend to be H, A, H^\pm-> W, Z, or h+MET + soft tracks so that single heavy Higgs production is characterized by the presence of high p_T W, Z or h bosons plus missing E_T. These new heavy Higgs boson signatures seem to be challenging to extract from SM backgrounds.

description: Physical activity during postpartum is both a recommended and an essential contributor to maternal health. Understanding the beliefs, barriers, and enablers regarding physical activity during the postpartum period can more effectively tailor physical activity interventions. The objective of this study was to document self-reported beliefs, barriers, and enablers to physical activity among a cohort of women queried at 3 and 12 months postpartum. Five questions about beliefs and two open-ended questions about their main barriers and enablers regarding physical activity and exercise were asked of 667 women at 3 months postpartum. Among the sample, 530 women answered the same questions about barriers and enablers to physical activity at 12 months postpartum.

description: Symbolic regression aims to find a function that best explains the relationship between independent variables and the objective value based on a given set of sample data. Genetic programming (GP) is usually considered as an appropriate method for the problem since it can optimize functional structure and coefficients simultaneously. However, the convergence speed of GP might be too slow for large scale problems that involve a large number of variables. Fortunately, in many applications, the target function is separable or partially separable. This feature motivated us to develop a new method, divide and conquer (D&C), for symbolic regression, in which the target function is divided into a number of sub-functions and the sub-functions are then determined by any of a GP algorithm. The separability is probed by a new proposed technique, Bi-Correlation test (BiCT). D&C powered GP has been tested on some real-world applications, and the study shows that D&C can help GP to get the target function much more rapidly.

description: We investigate the Weyl tensor algebraic structure of a fully general family of D-dimensional geometries that admit a non-twisting and shear-free null vector field k. From the coordinate components of the curvature tensor we explicitly derive all Weyl scalars of various boost weights. This enables us to give a complete algebraic classification of the metrics in the case when the optically privileged null direction k is a (multiple) Weyl aligned null direction (WAND). No field equations are applied, so that the results are valid not only in Einstein's gravity, including its extension to higher dimensions, but also in any metric gravitation theory that admits non-twisting and shear-free spacetimes. We prove that all such geometries are of type I(b), or more special, and we derive surprisingly simple necessary and sufficient conditions under which k is a double, triple or quadruple WAND. All possible algebraically special types, including the refinement to subtypes, are thus identified, namely II(a), II(b), II(c), II(d), III(a), III(b), N, O, IIi, IIIi, D, D(a), D(b), D(c), D(d), and their combinations. Some conditions are identically satisfied in four dimensions. We discuss both important subclasses, namely the Kundt family of geometries with the vanishing expansion (Theta=0) and the Robinson-Trautman family (Theta\not=0, and in particular Theta=1/r). Finally, we apply Einstein's field equations and obtain a classification of all Robinson-Trautman vacuum spacetimes. This reveals fundamental algebraic differences in the D>4 and D=4 cases, namely that in higher dimensions there only exist such spacetimes of types D(a)=D(abd), D(c)=D(bcd) and O.

description: New Ru(II) arene complexes containing 2,4-dihydroxyacetophenone based Schiff bases have been synthesized and characterized with FTIR, UV–visible, 1H NMR, 13C NMR and mass spectroscopies. Spectroscopic analysis revealed that the ligands coordinated to ruthenium(II) in a monobasic bidentate fashion via azomethine nitrogen and thiolate/oxalate. Antimicrobial activities of the compounds were evaluated with two bacteria (Staphylococcus aureus and Pseudomonas aeruginosa) and two fungi (Candida albicans and Candida tropicalis). The complexes displayed better antimicrobial activity over their ligands. In addition, the ligands and the complexes were analyzed for their anticancer potential against A549 (human lung carcinoma) and HeLa (human cervical cancer) cells, in which the complexes exhibited comparable activities against A549 (IC50 value is 21 ± 1 µM (1), 18 ± 1 µM (2)) and HeLa (IC50 value is 22.1 ± 0.9 µM (1), 20 ± 1 µM (2)) with the standard drug cisplatin (IC50 value is 25 ± 1 µM (A549) and 27 ± 1 µM (HeLa)). The non-toxic nature of the compounds has been confirmed with human umbilical vein endothelial cells (HUVEC cells). The obtained results highlighted the possibility of developing ruthenium arene complexes as anticancer agents.

description: Both self-reported indicators of stress and hormones such as cortisol and corticotrophin-releasing hormone (CRH) have been examined in relation to preterm birth. Although these hormones have been interpreted as biomarkers of stress, it is unclear whether psychosocial measures are empirically associated with biomarkers of stress in pregnant women.

description: In recent years, a number of observations have been made of the transits of 'Hot Jupiters', such as HD 189733b, which have been modelled to derive atmospheric structure and composition. As measurement techniques improve, the transit spectra of 'Super-Earths' such as GJ 1214b are becoming better constrained, allowing model atmospheres to be fitted for this class of planet also. While it is not yet possible to constrain the atmospheric states of small planets such as the Earth or cold planets like Jupiter, this may become practical in the coming decades and if so, it is of interest to determine what we might infer from such measurements. Here we have constructed atmospheric models of the Solar System planets from 0.4 - 15.5 microns that are consistent with ground-based and satellite observations and from these calculate the primary transit and secondary eclipse spectra (with respect to the Sun and typical M-dwarfs) that would be observed by a 'remote observer', many light years away. From these spectra we test what current retrieval models might infer about their atmospheres and compare these with the 'ground truths' in order to assess: a) the inherent uncertainties in transit spectra observations; b) the relative merits of primary transit and secondary eclipse spectra; and c) the advantages of directly imaged spectra. We find that secondary eclipses would not give sufficient information, but that primary transits give much better determination. We find that a single transit of Jupiter in front of the Sun could potentially be used to determine temperature and stratospheric composition, but for the Earth the mean atmospheric composition could only be determined if it were orbiting an M-dwarf. For both planets we note that direct imaging with sufficient nulling of the light from the parent star provides the best method of determining the atmospheric properties of such planets.

description: Radiative opacity is an important quantity in the modeling of stellar structure and evolution. In the present work we recall the role of opacity in the interpretation of pulsations of different kinds of stars. The detailed opacity code SCO-RCG for local-thermodynamic-equilibrium (LTE) plasmas is described, as well as the OPAMCDF project dedicated to the spectroscopy of LTE and non-LTE plasmas. Interpretations, with the latter codes, of several laser and Z pinch experiments in conditions relevant to astrophysical applications are also presented and our work in progress as concerns the internal solar conditions is illustrated.

description: The N2O2-tetradentate Schiff-base complex of zinc(II) was synthesized by the template reaction of 5-ethoxy-2-hydroxy-acetophenone-S-methylthiosemicarbazone and 2-hydroxy-benzaldehyde (1)/2-hydroxy-4-methoxy-benzaldehyde (2). The compounds were characterized by elemental analysis, UV–visible, FT-IR, 1H NMR spectra, and thermogravimetric analyses. Antioxidant activities of the compounds were determined with Cupric Reducing Antioxidant Capacity and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. The molecular geometries and vibrational frequencies were calculated using density functional theory (DFT/B3LYP) with the 6-311++G(d,p) basis set. The 1H NMR chemical shift values of the ligand and complexes in the ground state were calculated with the gauge-independent atomic orbital (GIAO) approach applying the same method and the basis set and compared with the experimental data. Using the TD-DFT method, electronic absorption spectra of the complexes were predicted at the same level. Also, the non-covalent interaction (NCI) plot index analysis reveals the presence of different kinds of non-covalent interactions in all complexes.

description: Viruses are nanoscale entities containing a nucleic acid genome encased in a protein shell called a capsid, and in some cases surrounded by a lipid bilayer membrane. This review summarizes the physics that govern the processes by which capsids assembles within their host cells and in vitro. We describe the thermodynamics and kinetics for assembly of protein subunits into icosahedral capsid shells, and how these are modified in cases where the capsid assembles around a nucleic acid or on a lipid bilayer. We present experimental and theoretical techniques that have been used to characterize capsid assembly, and we highlight aspects of virus assembly which are likely to receive significant attention in the near future.

description: We present a study on the Yoneda-Dress construction of biset functors of linear representations over a field of characteristic zero. We give a characterization of their lattices of ideals and we provide a criterion of vanishing for their essential algebras. We provide a parametrization for a family of simple modules over the functor of rational representations. Finally, we give an equivalence between the category of modules over the shifted functor of complex class functions and the category of modules over a semisimple algebra.
