Bacterial filaments recover by successive and accelerated asymmetric divisions that allow rapid post‐stress cell proliferation

Filamentation is a reversible morphological change triggered in response to various stresses that bacteria might encounter in the environment, during host infection or antibiotic treatments. Here we re‐visit the dynamics of filament formation and recovery using a consistent framework based on live‐cells microscopy. We compare the fate of filamentous Escherichia coli induced by cephalexin that inhibits cell division or by UV‐induced DNA‐damage that additionally perturbs chromosome segregation. We show that both filament types recover by successive and accelerated rounds of divisions that preferentially occur at the filaments' tip, thus resulting in the rapid production of multiple daughter cells with tightly regulated size. The DNA content, viability and further division of the daughter cells essentially depends on the coordination between chromosome segregation and division within the mother filament. Septum positioning at the filaments' tip depends on the Min system, while the nucleoid occlusion protein SlmA regulates the timing of division to prevent septum closure on unsegregated chromosomes. Our results not only recapitulate earlier conclusions but provide a higher level of detail regarding filaments division and the fate of the daughter cells. Together with previous reports, this work uncovers how filamentation recovery allows for a rapid cell proliferation after stress treatment.

Thermodynamics / turbulence analogy modelling dissipating molecular gas flows for high Knudsen numbers

Modelling micro channel flows momentum and heat diffusion / convection are recent parameters modelling the molecule velocity distribution. Macroscopic models describe velocity and energy / enthalpie with integrals of mass increments. Using microscopic models motion and forces of a molecular flow have to be computed by models of physical properties, whose are described by statistical power moments of the molecule velocity. Therefore dilute flows have to be investigated in small channels with a mean free path length of molecules higher than the channel width of the the micro channel itself (λ0≥H0). Modelling this process by a continuous flow the boundary conditions have to be modified (e.g. [6]). The present model uses the statistical approximation of the molecule velocity distribution to simulate the behaviour of this discrete flow with a weighted averaged molecule velocity ∼ξi, its standard deviation σ and the characterisic molecule collision rate z. The number density N per volume V near one position is used for the weighting factor averaging method describing the mean molecule velocity. The present model is validated computing Poiseuille and Couette flows with different Knudsen numbers. Showing the advantages of the present model the simulation results are compared with simulation results of the wall–distance depending diffusivity model of Lockerby and Reese [4] and BGK results of a Lattice–Boltzmann simulation.

On the total variation of a third-order semi-discrete central scheme for 1D conservation laws

In this work, we present a third-order, semi-discrete, central-upwind scheme for computing approximate solutions of 1D systems of conservation laws. We combine the third-order CWENO reconstruction proposed in Levy et al., the semi-discrete central-upwind numerical flux proposed in Kurganov et al. and the third-order TVD Runge—Kutta method, proposed in Shu and Osher. We are interested in the behavior of the total variation of the approximate solution obtained with this scheme. Also we test our scheme on both scalar and gas dynamics problems. We observe that the total variation of computed solutions is close to the total variation of the exact solution or a reference solution.
High-dynamic range SAXS data acquisition with an X-ray image intensifier

Data with a wide dynamic range of intensity can be collected with a pinhole high-brilliance small-angle X-ray scattering (SAXS) camera using an image-intensified charge-coupled device (CCD) detector. The point spread function (PSF) of this detector has a narrow peak with a broad low tail such that a high level of scattered intensity at small angles can cause a significant background in the detector elements at higher angles. A correction scheme for the long tail of the PSF of the detector is needed when this integrating area detector is used for measuring intensity that spans a dynamic range of four to five orders of magnitude. A procedure is described for measuring the PSF contribution by masking a small part of the detector from the scattered radiation with an absorbing material. In order to measure the PSF, it is necessary to use a high-intensity spot, which is readily achieved by using a sample that scatters strongly at small angles. Although this intensity is spread over many pixels, the sharp features in the scattering from the silica sample chosen for this study permit one to obtain simultaneously both the narrow and the broad parts of the PSF. The data are compared with the actual scattering function, which has been measured exactly with a point-geometry Bonse–Hart camera. The advantages of this procedure are discussed.
Flattening of a Nearly Plane Solid Surface due to Capillarity

The relaxation of a nearly plane surface to flatness is discussed under the assumption that all surface properties are independent of orientation. A general solution is obtained for the combined action of the transport processes of viscous flow, evaporation‐condensation (in a closed system), volume diffusion, and surface diffusion. Green's function solutions are developed for each of the transport processes separately, and criteria are obtained to decide which process dominates. The initial forms of these solutions represent point concentrations (particles), or line concentrations (wires) of material set upon an infinite plane. The progressive topographical developments described by the formulas are idealized representations of the latter stages of the sintering of small wires and particles to a plane.
Stochastic simulation of entangled polymeric liquids in fast flows: Microstructure modification

We have modified the full-chain stochastic tube (XDS) model developed by Xu et al. [J. Rheol. 50, 477–494 (2006)] to simulate the rheology of entangled melts and solutions of linear monodisperse polymers. The XDS model, which has a single adjustable parameter that is equivalent to the Rouse time, successfully describes steady and transient shear and normal stress data at low to moderate rates, but the results deviate systematically from experimental data at high rates. The algorithm for re-entanglement was revised, and a configuration-dependent friction coefficient (CDFC), as originally proposed by Giesekus, was incorporated to account for microstructural change of the tube away from equilibrium. The simulation results from the modified model significantly reduce the deviation from the experimental data in shear, and they also agree well with extensional data for entangled solutions, including an initial −0.5-power dependence of the steady extensional viscosity on extension rate. We also applied the CDFC .
The Impact of External Information on People's Aesthetic Attention

: This study aims at investigating if receiving different kinds of external information could make impacts on people's aesthetic experience. Thirty participants were randomly recruited from an office building in Guangzhou, China. Participants were assigned to three groups respectively. Each group viewed images of two females with different features after reading different kinds of articles. During the experiment, an eye tracker was used to record participants’ visual data which reflects their corresponding aesthetic attention. The experiment reveals that the current mainstream aesthetic preferences for Chinese females are “fair” skin tone and "slim" body shape. Meanwhile, after reading Article promoting different views, participants’ visual attention distribution on one of the females as a stimulus significantly changed. Therefore it can be concluded that external information has an impact on people’s aesthetic experience.
The Role of Radio Surveillance in the Fight Against Deforestation in Rufiji, Tanzania

This paper examines the role of radio surveillance in the fight against deforestation in Rufiji, Tanzania. It presents the findings of a study that was guided by three research questions: (i) What techniques are used by radio programme producers in alerting people on the dangers of deforestation in Tanzania? (ii) How useful and helpful is forest information communicated through the radio to Rufiji community members? (iii) To what extent does the radio influence forest conservation behaviour among community members in Rufiji? Data were collected from a series of Urithi Wetu programme on TBC Taifa, and its content was analysed qualitatively to yield input that depicts the perceived role of radio surveillance. Complementary data were collected using questionnaires and focus group discussions. The findings reveal that the radio has largely failed to use instrumental surveillance function of the environment to empower community members find alternative sources of income generation and refrain from actions that are detrimental to forest conservation efforts. In fact, the findings expose the relative limitation of the success of the radio in both scope and intensity in using several techniques to make its audiences aware of impending and prevailing threats associated with TBC-Taifa tree-felling. Thus, remedial measures would include a shift in focus to solution-based programmes and integration of the views of the community members in radio programmes to optimise the impact on the target audiences.
Nano‐ and Microscale Particles in Vortex Motions in Earth’s Atmosphere and Ionosphere

Vortex motions in the atmosphere are shown to be closely connected with dynamics of the dust nano‐ and microscale particles. The mechanism by which nano‐ and microscale particles are transported from the troposphere into the lower stratosphere by synoptic‐scale vortices, simulated by the soliton solutions to the Charney‐Obukhov equations (Rossby vortices), is described. Redistribution of dust particles in the ionosphere as a result of vortical motions is discussed. It is shown that excitation of acoustic‐gravitational vortices at altitudes of 110–130 km as a result of development of acoustic‐gravitational wave instability, associated with nonzero balance of heat fluxes, owing to solar radiation, water vapors condensation, infrared emission of the atmosphere, and thermal conductivity, leads to a substantial transportation of dust particles and their mixing at altitudes of 110–120 km. One of the ways of transportation of dust particles in the ionosphere is shown to be vertical flows (streamers), which are g.
Assessing the Effects of Steel Composition on Surface Cracks in Continuous Casting with Solidification Simulations and Phenomenological Quality Criteria for Quality Prediction Applications

Crack formation is an issue that significantly undermines the quality and productivity of steel production. In previous studies, a solidification and microstructure model known as InterDendritic Solidification (IDS) has been developed and implemented in various slab casters in Finland. Numerous quality criteria have been derived from the model outputs to identify the general phenomena which increase the risks of defect formation in different steel grades. The aim of this study is to study the feasibility of these criteria in providing input data for predicting quality in a group of defect‐prone steel grades with rule‐based decision‐making and machine learning algorithms. To this end, three steel grades are studied by utilizing measured compositions and comparing the quality criteria with plant data regarding reported defects. The computations are carried out by coupling IDS with a fundamental model for simulating heat transfer (Tempsimu) in continuous casting. The results indicate that for the studied steel grades, phenomenological quality criteria can be applied to predict the formation of cracks and other defects. Trends contributing to increased risks of defect formation are identified for all the studied steel grades, and possibilities for avoiding defects by changes in the compositions of these steel grades are also proposed.

Laminar Flow Past a Circle in a Shear Flow

A numerical solution of the equations governing time‐dependent, viscous, incompressible fluid flow past a circle is presented for Reynolds number 400. The free‐stream velocity profile corresponds to the time‐averaged flow of a turbulent jet. The location and strength of the jet are adjusted so that the free stream approximates a linear shear flow in the vicinity of the circle. The asymmetry of the free stream causes a shift of the upstream stagnation streamline (the Pitot‐tube displacement effect) and small biases in the lift and torque exerted upon the circle. This lift bias is suggested as a contributing factor in the observed stability of raindrops in vertical wind tunnels. Contour plots of the vorticity and stream function are compared with histories of the pressure distribution, drag, lift, torque, and separation angles. These comparisons show how the asymmetry of the free stream manifests itself in terms of fine details within the flow pattern around the circle.
Higher Accuracy Methods for Second-Kind Volterra Integral Equations Based on Asymptotic Expansions of Iterated Galerkin Methods

On the basis of asymptotic expansions, we study the Richardson extrapolation method and two defect correction schemes by an interpolation post-processing technique, namely, interpolation correction and iterative correction for the numerical solution of a Volterra integral equation by iterated finite element methods. These schemes are of higher accuracy than the postprocessing method and analyzed in a recent paper [5] by Brunner, Q. Lin and N. Yan. Moreover, we give a positive answer to a conjecture in [5].
Spin-Polarized Vacuum Tunneling into the Exchange-Split Surface State of Gd(0001)

Spin-polarized tunneling is demonstrated on Gd(0001) thin films using ferromagnetic probe tips in a low-temperature scanning tunneling microscope. The magnetic field dependent asymmetries in the differential tunneling conductivity are found at bias voltages which correspond to the energies of the spin components of the exchange-split Gd(0001) surface state. Maps of the spatial variation of the asymmetry reveal the magnetic structure of Gd(0001) thin films with a lateral resolution better than 20 nm. It is found that magnetic tip coatings thicker than 100 monolayers Fe may modify the sample domain structure due to the stray field of the tip.
Variance stabilization and the bootstrap

SUMMARY We investigate the use of a variance stabilizing transformation for the computation of a bootstrap t confidence interval. The transformation is estimated in an 'automatic' manner through an initial bootstrap step. A bootstrap t interval is then computed for the variance stabilized parameter and the interval is mapped back to the original scale. The resultant procedure is second-order correct in some settings, invariant and in a number of examples it performs better than the usual untransformed bootstrap t interval. It also requires far less computation. The new interval is compared with Efron's BCa procedure and the two methods are seen to produce similar results.
The Impact of Strategic Alignment and Strategic Awareness on Strategic Performance: Evidence from Jordan

The current study's purpose is to measure the impact of strategic alignment and strategic awareness on strategic performance in Jordanian Industrial Companies that are working at the Al – Hussein bin Abdullah II qualified industrial zone (QIZ) in Al-Karak Governorate. The study used a quantitative approach. In addition, the questionnaire was developed to collect the data from the target sample. Besides, the current study consisted of 220 respondents. Two hundred twenty questionnaires were distributed to the top and middle management such as managers, deputies of managers, and heads of departments. Furthermore, the SPSS software version (25) was used to test the study's hypotheses. The current study found that strategic alignment has a positive and significant impact on strategic performance. Furthermore, strategic awareness has a positive and significant impact on strategic performance. The current study recommends that Jordanian industrial companies should develop and improve their information technology strategy to be aligned and fit with their organizational strategy which leads to exploiting the opportunities effectively and efficiently and thus improving strategic performance.
Electronic structure of ensembles of gold nanoparticles : Size and proximity effects

The valence-band electronic structure of alkanethiol stabilized gold nanoparticles (NPs) with different core sizes has been studied using x-ray photoemission spectroscopy. A reduction of density of state near the Fermi level is observed for small particles (< 3 nm diam) that are separated by more than 1 nm. A significant cross-coupling between the particles is found when their separation is decreased below 1 nm that restores the density of states at the Fermi edge. The observations are interpreted as a result of changes in the screening of Coulomb blockade effects in the NP system due to tunneling between particles at the shorter separations.
Social Media in Social CRM: Systematic literature review

Social CRM has become a concept that changes traditional CRM into technological CRM that uses web 2.0 or social media to engage with the customer. SM usage growth is so rapid that companies compete to use social media as their marketing to improve engagement and services to their customers. This research aims to find the role of SM and factors that can measure the influence of SM in S-CRM. This study uses SLR to identify the parts of SM in the industry that implements social CRM and measurement that comes out of the TOE, TAM and IS success models.

Differences in religious and spiritual practice variables between Canadian counselors and psychologists

This article investigates whether there are differences in religious and spiritual (R/S) beliefs, attitudes, practices, training, and self-assessed competence between counselors and psychologists in Canada. Researchers surveyed 307 mental health professionals in Canada with two standardized measures (the Assessment of Spirituality and Religious Sentiments Scale and the Duke University Religion Index) and various other questions corresponding to variables investigated or alluded to in past research. We hypothesized that, compared with psychologists, counselors would (a) have stronger personal R/S beliefs, (b) demonstrate more positive attitudes about the appropriateness of using R/S techniques with clients, (c) utilize R/S techniques more in sessions, (d) possess more positive attitudes toward training in this area, and (e) have higher self-assessed competence for working with R/S clients. These hypotheses were generally supported except for the last one: there were no significant differences found between counselors and psychologists in self-assessed competence in working with R/S clients. We compare our findings to those of extant research, particularly the study by Plumb who examined counselors in Canada. On the basis of our findings, we advocate for more systematic cultivation of R/S competence in programs for both counselors and psychologists in Canada.

Inertial waves in a rotating spherical shell

The structure and spectrum of inertial waves of an incompressible viscous fluid inside a spherical shell are investigated numerically. These modes appear to be strongly featured by a web of rays which reflect on the boundaries. Kinetic energy and dissipation are indeed concentrated on thin conical sheets, the meridional cross-section of which forms the web of rays. The thickness of the rays is in general independent of the Ekman number E but a few cases show a scaling with E1/4 and statistical properties of eigenvalues indicate that high-wavenumber modes have rays of width O(E1/3). Such scalings are typical of Stewartson shear layers. It is also shown that the web of rays depends on the Ekman number and shows bifurcations as this number is decreased. This behaviour also implies that eigenvalues do not evolve smoothly with viscosity. We infer that only the statistical distribution of eigenvalues may follow some simple rules in the asymptotic limit of zero viscosity.
