description: The small multidrug resistance (SMR) protein, EmrE transports quaternary cationic compounds (QCC) across the cytoplasmic membrane in the Gram-negative bacterium Escherichia coli. EmrE over-expression results in the reduction of host pH and osmotic tolerance, likely through EmrE-mediated biological QCC based osmoprotectant efflux. It is not known how the substrates translocated by EmrE into the periplasmic space escape across the outer membrane (OM). The observation that an OM protein, OmpW, participates in EmrE-mediated substrate efflux provided the hypothesis that additional OM and periplasmic proteins participate in the process. By conducting alkaline pH based growth phenotype screens I identified 10 additional proteins that may contribute to the EmrE-mediated osmoprotectant efflux: GspD, HofQ, YccZ, AcrA, EmrA, EmrB, ProX, OsmF, DcrB and YggM. Further screening of these using a hyperosmotic stress ± betaine growth phenotype assay identified OmpW and two periplasmic proteins, DcrB and YggM, to have involvement in the EmrE-mediated export of betaine.
Three essays on family labour supply and health over the life cycle
Creators: name: Turner, Laura
Publisher: name: University of British Columbia
Year: 2010

description: The three essays in this thesis explore how intrahousehold decision making interacts with evolving health, disability shocks and aging to determine life cycle patterns of labour supply and retirement among Canadian and U.S. households. One of the main roles of marriage and cohabitation is to provide individuals with insurance against idiosyncratic risk such as health and disability shocks. The extent and effects of this insurance depend on how household members interact and delegate tasks--for instance, whether they can specialize and easily transition between home-based or market-based work--and the extent to which household members commit to and cooperate with each other. The first two chapters of the thesis document and provide a structural explanation for the fact that, in general, marriage is associated not only with better health outcomes but also with better economic outcomes conditional on health status. The final chapter suggests that these better outcomes, and the role of public policy in facilitating them, may be contingent on how cooperative household members are with each other when making career and retirement decisions. In general, the results suggest that household-level interactions have important implications for aggregate labour supply and human capital; for the role and appropriate use of public policy; and for the welfare of individuals confronted with uncertainty over the length and productivity of their working life.
Third-order and fifth-order nonlinear spin-current generation in $g$-wave and $i$-wave altermagnets, and perfectly nonreciprocal spin-current in $f$-wave magnets

description: A prominent feature of $d$-wave altermagnets is the pure spin current generated in the absence of spin-orbit interactions. In the context of symmetry, there are the $s$-wave, the $p$-wave, the $d$-wave, the $f$-wave, the $g$-wave and the $i$-wave magnets. In this paper, making an analytic study of two-band Hamiltonian systems coupled with electrons, we demonstrate unexpectedly that only the $\ell $-th order nonlinear transverse spin current proportional to $E^{\ell }$ is generated in higher-wave symmetric magnets when the number of the nodes is $\ell +1$. Here $E$ is applied electric field. The nonlinear spin current is essential provided the linear spin current is absent. Indeed, only the third-order nonlinear spin current is generated in $g$-wave altermagnets, while only the fifth-order spin current is generated in $i$-wave altermagnets. In particular, only the second-order nonlinear spin current is generated in $f$-wave magnets, which leads to a perfect nonreciprocal spin current. On the other hand, there is no spin-current generation in $p$-wave magnets.

Searches for Low Mass Higgs Boson at the Tevatron

Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: We present the result of the searches for a low mass Standard Model Higgs boson performed at the Tevatron ppbar collider (sqrt(s) =1.96 TeV) by the CDF and D0 experiments with an integrated luminosity of up to 8.5 fb^-1. Individual searches are discussed and classified according to their sensitivity. Primary channels rely on the associate production with a vector boson (WH or ZH) and the H->bbbar decay channel (favored for M_H<135 GeV/c^2). Event selection is based on the leptonic decay of the vector boson and the identification of b-hadron enriched jets. Each individual channel is sensitive, for M_H=115 GeV/c^2, to less than 5 times the SM expected cross section and the most sensitive channels can exclude a production cross section of 2.3 x sigma_H SM. Secondary channels rely on a variety of final states. Although they are from 2 to 5 times less sensitive than any primary channel, they contribute to the Tevatron combination and, in some cases, they pose strong constrains on exotic Higgs boson models.

description: Accurate measurement of hydrogen in steels is one of the greatest challenges in the field of applied science. Even though research on hydrogen in steels has been carried out over the last ten decades, very little progress has been made in fundamental areas because of the lack of a reliable method for measuring hydrogen within a steel. The hydrogen atom's small size and its one atomic orbit have caused di culties in applying readily established measuring techniques to measure the simplest atom. The small size of the hydrogen atom has also made leak proofing the hydrogen measuring systems extremely difficult; thus, most apparatus are vulnerable to leaking. Additionally, the need to measure extremely small quantities and the high degree of statistical variation in the measured quantities have made the measured hydrogen quantities uncertain. The main task of this research study was to design and construct a new, direct hydrogen measuring device called the Temperature Vacuum Hydrogen System (TVHS) and to explore some higher temperature measurements of hydrogen in steel using this new device. This thesis provides a study of the direct hydrogen measuring methods available, the improvements implemented on the standard eudiometer method to improve the method's accuracy and the users' safety, a discussion of the problems faced during the construction and operation of the TVHS, and the solutions applied to mitigate them. The hydrogen volumes measured using the TVHS at 50, 150, 250, and 350 C in hydrogen charged AISI 1020 steel samples; and temperature-time relationships for measured hydrogen quantities; an equation to correlate the measured amounts from the TVHS method with the amounts measured using the standard eudiometer method are also provided in this thesis. Key findings of the tests carried out using the TVHS were that a significantly higher amount of hydrogen egressed at 350 C compared to the amounts that egressed at lower test temperatures and the time durations took longer than expected for stabilizing the egressed hydrogen amounts. Equations to predict hydrogen amounts egress from steel samples that are charged with low hydrogen concentrations were also derived. In addition, a chemical analysis on a steel sample immersed in mercury at low-elevated temperatures for an extended period showed a possibility for hot mercury to dissolute carbon from the pearlite structure of the steel, leaving the iron in the structure.

description: The higher order moments of the net-baryon distributions in relativistic heavy ion collisions are useful probes for the QCD critical point and fluctuations. Within a simple model we study the colliding energy and centrality dependence of the net-proton distributions in the central rapidity region. The model is based on considering the baryon stopping and pair production effects in the processes. Based on some physical reasoning, the dependence is parameterized. Predictions for the net-proton distributions for Au+Au and Pb+Pb collisions at different centralities at $\sqrt{s_{NN}}$=39 and 2760 GeV, respectively, are presented from the parameterizations for the model parameters. A possible test of our model is proposed from investigating the net proton distributions in the non-central rapidity region for different colliding centralities and energies.

description: Synchronization with noise is important for understanding biophysical processes at nano- and micro-meter scales, such as neuronal firing and flagellar rotations. To understand the energetics of these processes, stochastic thermodynamics approaches are useful. Due to large fluctuations in a small system, ensemble averages of thermodynamic quantities are not sufficient to characterize the energetics of an individual sample. In this paper, we use a model for synchronization of bacterial flagella as an example, and develop an approximation method for analyzing the phase and heat dissipation in trajectories for different noise realizations. We describe the {temporal evolution} of the phase difference and heat dissipation as stochastic processes, and verify the analytical results by numerical simulations.

description: There is increasing concern regarding the adverse effects of contaminants commonly found in the environment. Recent studies point to the endocrine disrupting effects of contaminants on fish in a number of Alberta Rivers. In the present thesis I utilized 1H-NMR metabolomics to study the effects of environmentally relevant concentrations of NP, DEHP, FS, BPA as well as mixture of these contaminants on metabolism of male goldfish. I demonstrated that these contaminants disrupt metabolism in organ-dependent and season-dependent manner. When present in mixture, these compounds disrupt metabolism differently from individual contaminants. Additionally, comparing the effects of contaminants with endogenous hormones (E2, T, T3) led me to conclude that contaminants with well documented endocrine disrupting ability exert a complex metabolic response in goldfish through multiple receptor mediated routes different from endogenous hormones.
Complete Bundle Moduli Reduction in Heterotic String Compactifications

Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A major problem in discussing heterotic string models is the stabilisation of the many vector bundle moduli via the superpotential generated by world-sheet instantons. In arXiv:1110.6315 we have discussed the method to make a discrete twist in a large and much discussed class of vector bundles such that the generation number gets new contributions (which can be tuned suitably) and at the same time the space of bundle moduli of the new, twisted bundle is a proper subspace (where the 'new', non-generic twist class exists) of the original bundle moduli space; one thus gets a model, closely related to the original model one started with, but with enhanced flexibility in the generation number and where on the other hand the number of bundle moduli is {\em somewhat} reduced. Whereas in the previous paper the emphasis was on examples for the new flexibility in the generation number we here classify and describe explicitly the twists and give the precise reduction formula (for the number of moduli) for SU(5) bundles leading to an SU(5) GUT group in four dimensions. Finally we give various examples where the bundle moduli space is reduced {\em completely}: the superpotential for such {\em rigid} bundles becomes a function of the complex structure moduli alone (besides the exponential Kahler moduli contribution).

description: In the present study, we explore the properties of generalized parton distributions (GPDs) for the kaon and pion within the framework of the nonlocal chiral quark model (NL$χ$QM). Valence quark GPDs of the kaon and pion are analyzed with respect to their momentum fraction $x$ and skewness $ξ$ dependencies in the DGLAP and ERBL regions. We observe that the asymmetry of the current quark masses in kaon results in a significant distortion of the quark GPDs in kaon near $ξ=1$, compared to the case of the pion. The quark GPDs of the kaon and pion are evolved to $μ^2 = 4$ GeV$^2$ and 100 GeV$^2$ by the QCD evolution equation at one-loop order using the \texttt{APFEL++} package. We find that the produced sea quarks and gluons are largely suppressed as $ξ$ becomes nonzero, predominantly confined within the ERBL region. We subsequently examine the polynomiality of the GPDs and numerically obtain the electromagnetic and gravitational form factors of the kaon and pion. For the kaon, gravitational form factor ratios $A_{\bar s/K^+}(0)/A_{s/K^+}(0) = 1.26$ and $D_{\bar s/K^+}(0)/D_{s/K^+}(0) = 1.10$ are reported and compared with results from other effective models.

description: We first present a generalized criterion for maximally entangled states of 2, 3, 4, 5, 6, 8 and in theory to arbitrary-number qubits. By this criterion, some known highly entangled multi-qubit states are examined and a new genuine eight-qubit maximally entangle state is obtained. For the 4, 7 and 8 qubits system in which no maximally multi-qubit entangled states (MMES) is thought to exist before, we find that the proved and most suspected MMESes, are not completely mixed in subsystem with a critical-number qubits, below which the subsystems are all completely mixed. We believe that the new criterion and MMES can play important role in quantum information technology, such as the teleportation and dense coding.
Seeking aboriginal mothers : repairing colonial disruptions through Marie Clements' the unnatural and accidental women
Creators: name: Johnston, Laura Lynne
Publisher: name: University of British Columbia
Year: 2010

description: Attempting to understand mainstream dismissal and degradation of missing and murdered Aboriginal women, this thesis investigates Marie Clements’ The Unnatural and Accidental Women. Retelling the story of Gilbert Paul Jordan’s murder of ten women, predominantly Aboriginal, from Vancouver’s Downtown Eastside, The Unnatural and Accidental Women exposes racist media representations that tell little of the women, emphasizinig instead their high levels of alcohol and Aboriginal background. Perpetuating stereotypes of Aboriginal women as promiscuous and alcoholic, such representations overlook Jordan’s methods of poisoning his victims with alcohol. Central to this thesis is the mother/daughter relationship within the play. Abandoned by her mother at age four, Rebecca begins to search for her mother on the drug-addiction riddles streets of Vancouver’s downtown “Skid Row.” Asking the question: Why do high numbers of Aboriginal women leave their families to live impoverished and often addicted lives full of danger and isolation?, this thesis explores governmental policies disenfranchising Aboriginal women and enforcing the removal Aboriginal children into residential schools and white foster homes. Within this context, this thesis argues that Aunt Shadie acts as a maternal metaphor, reflecting Aboriginal philosophies that honour the significance of the mother/child bond. Clements’ play can be argued to offer a maternal counter-narrative to dominant discourses of Aboriginal womanhood.

description: The inverse scattering problem of the three-dimensional Schroedinger equation is considered at fixed scattering energy with spherically symmetric potentials. The phase shifts determine the potential therefore a constructive scheme for recovering the scattering potential from a finite set of phase shifts at a fixed energy is of interest. Such a scheme is suggested by Cox and Thompson [3] and their method is revisited here. Also some new results are added arising from investigation of asymptotics of potentials and concerning statistics of colliding particles. A condition is given [2] for the construction of potentials belonging to the class L_1,1 which are the physically meaningful ones. An uniqueness theorem is obtained [2] in the special case of one given phase shift by applying the previous condition. It is shown that if only one phase shift is specified for the inversion procedure the unique potential obtained by the Cox-Thompson scheme yields the one specified phase shift while the others are small in a certain sense. The case of two given phase shifts is also discussed by numerical treatment and synthetic examples are given to illustrate the results. Besides the new results this contribution provides a systematic treatment of the CT method.

description: Passive seismic data recorded in observation wellbores for hydraulic fracture monitoring are usually used to detect P- and S-wave arrivals from induced microseismic events. The time arrivals for these events are used to compute source locations to build a fracture location map. Along with these arrivals are a number of other coherent signal and noise events. The primary objective of this thesis is to examine various other types of coherent signal and noise on four microseismic datasets. This thesis is made up of four separate studies. The first study examines numerous coherent low-frequency (<100 Hz) arrivals characterized by conspicuous dispersion and quasi-linear moveout. Their apparent velocities and dispersion characteristics are consistent with Lamb waves, an elastic guided wave that propagates within finite media such as plates or cylindrical casing. Lamb waves may be used for monitoring degradation of casing cement over time. The second study examines two datasets to characterize frequency shifts in discrete narrow passbands caused by wellbore acoustic transmissivity due to geophone clamping. The passbands changed throughout two fracture stimulations in proportion to the hydraulic fracture pressure. Analytical and finite-element models suggest that these temporal variations may be caused by a relative change in geophone clamping force as the pressure external to the wellbore varies. This sensitivity suggests that passive seismic monitoring can be used for downhole detection of relative stress changes. The third study focuses on frequency content variations of 20 high S/N P- and S-wave events. The 20 events were grouped into four clusters based upon a geolocation algorithm and event cross-correlations. Spectral analysis shows variation in the signal within event sets. A 2-D elastic finite-difference simulation using a layered model shows that this variation could be ascribed to path effects associated with propagation of the signal from the source to the receivers. The fourth study examines a potential long-period long-duration (LPLD) seismic event and analyzes the phenomena in detail. LPLD events observed on microseismic data have been likened to deep low-frequency tremor attributed to slow-slip processes along pre-existing fractures or strike-slip regimes at subduction zones. The event may be the result of hydraulic fracture fluid leak-off out of the intended zone into a pre-existing fracture.

description: We put forward a theory on the optical force exerted upon a dipolar particle by a stationary and ergodic partially coherent light field. We show through a rigorous analysis that the ensemble averaged electromagnetic force is given in terms of a partial gradient of the space variable diagonal elements of the coherence tensor. Further, by following this result we characterize the conservative and non-conservative components of this force. In addition, we establish the propagation law for the optical force in terms of the coherence function of light at a diffraction plane. This permits us to evaluate the effect of the degree of coherence on the force components by using the archetypical configuration of Young's two apertures diffraction pattern, so often employed to characterize coherence of waves.

description: With the increasing popularity of herbomineral preparations in healthcare, a new proprietary herbomineral formulation was formulated with ashwagandha root extract and minerals viz. zinc, magnesium, and selenium. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the herbomineral test formulation using mice splenocytes. The test formulation was divided into two parts. One part was the control without the Biofield Treatment. The other part was labelled the Biofield Treated sample, which received the Biofield Energy Healing Treatment remotely from twenty renowned Biofield Energy Healers. The splenocyte cells were exposed with the test formulation at ranges of 0.00001053 to 10.53 µg/mL for cell viability by MTT assay, with cell viability ranging from 77.50% to 176.52%. TNF-α was significantly inhibited by 15.88%, 15.28%, 12.30%, 12.60%, and 22.72% at 0.00001053, 0.001053, 0.1053, 1.053, and 10.53 µg/mL, respectively in the Biofield Treated test formulation compared to the vehicle control (VC). TNF-α was significantly reduced by 2.33% and 8.35% at 1.053 and 10.53 µg/mL, respectively compared to the untreated test formulation. IL-1β was significantly reduced by 30.81%, 27.36%, 23.92%, 18.40%, 11.27%, and 21.16% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, and 1.053 µg/mL, respectively in the Biofield Treated test formulation compared to the VC. IL-1β was significantly reduced by 48.63% (p≤0.001) and 15.28% at 0.00001053 and 0.0001053 µg/mL, respectively in the Biofield Treated test formulation compared to the untreated test formulation. MIP-1α expression was inhibited by the Biofield Treated test formulation and showed immunosuppressive activity at 0.01053, 0.1053, 1.053, and 10.53 µg/mL by 22.33%, 16.25%, 15.58%, and 21.83%, respectively compared to the VC. The Biofield Treated test formulation significantly reduced the MIP-1α expression by 13.27% and 15.67% (p0.05) at 0.01053 and 10.53 µg/mL, respectively compared to the untreated test formulation. The results showed the expression of IFN-γ was significantly reduced by 33.45%, 25.38%, 37.15%, 27.74%, 32.44%, 23.03%, and 44.21% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, 1.053, and 10.53 µg/mL, respectively in the Biofield Treated test formulation compared to the VC. Further, the IFN-γ level was significantly decreased by 19.02% at 10.53 µg/mL in the Biofield Treated test formulation compared to the untreated test formulation. Overall, the results demonstrate that The Trivedi Effect® Biofield Energy Healing (TEBEH) significantly enhanced the anti-inflammatory and immunomodulatory properties of the treated formulation, and may also be useful in organ transplants, anti-aging, and stress management by improving overall health and quality of life.

description: Cosmic rays are the highest energy particles available for our study and as such serve as excellent probes of the effects of Lorentz Invariance Violations, which are expected to increase with energy. This general paradigm is investigated in this paper by studying the effects of such violations within the Coleman-Glashow model in which each particle species may have its own maximum attainable velocity, even exceeding that of light \textit{in vacuo}. The particular focus here is that the muon neutrino may have the maximum speed exceeding that of light. We show that such an assumption leads to the elongation of the decay lifetime of the pion that increases with energy over and above the time dilation effects. We provide a transparent analytical derivation of the spectral intensities of muon neutrinos and muons generated in the Earth's atmosphere by cosmic rays. In this derivation we not only account for elongation of the pion lifetime, but also for the loss of energy by the neutrinos by radiation of the electron-positron pairs through the Cohen-Glashow process, during their propagation. We then compare the theoretical spectra with observations of neutrinos and muons from large instruments like IceCube and BUST to set a limit of $\sim10^{-13}$ on the fractional excess speed of neutrinos over that of light. We also show that the ratio of the spectral intensities of downward and upward moving neutrinos at various angles constitute a diagnostic exclusively for the Cohen-Glashow process, which may be searched for in the IceCube data set. We conclude the paper with several comments, including those related to improvements of these tests when definite signals of GZK neutrinos will be observed.

Study of OCS-R complexes (R indicates certain hydrocarbons with chain or ring structures) commenced with the study of OCS-acetylene complex in the region of nu1 stretching fundamental of OCS (~2060 cm-1). Two bands are observed and assigned to near-parallel and T-shaped isomers of OCS-acetylene. In addition to the normal species, the deuterated isotopic form is also studied. Simple looking bands characteristic of a T-shaped structure are observed for complexes formed between OCS and ethylene, allene, propyne, dimethylacetylene, benzene, and cyclo-octatetraene. All the bands are observed to be red-shifted from the OCS monomer nu1 frequency. Infrared bands in the CO2 nu3 region (~2350 cm-1) are assigned to carbon dioxide clusters, (CO2)N, with N=6, 7, 9, 10, 11, 12, and 13. Assignments are aided by cluster calculations using two reliable CO2 intermolecular potential functions. These are the largest molecular clusters studied by infrared spectroscopy with rotational resolution. Two highly symmetric isomers with S6 and S4 symmetries are observed for (CO2)6. (CO2)13 is also symmetric with S6 symmetry, but all the remaining clusters are asymmetric tops. The bands have increasing blue-shifts with increasing cluster size, similar to predictions of resonant dipole-dipole model but considerably larger in magnitude. N2O tetramer is studied in the region of N2O nu1 fundamental (~2220 cm-1). The previously observed oblate isomer of (N2O)4 is studied with considerably higher resolution. Isotopic substitution has confirmed a structure with D2d symmetry for this isomer. In addition to the oblate isomer, a new prolate isomer of (N2O)4 with S4 symmetry is observed.

description: Although the rapid neutron-capture process, or r-process, is fundamentally important for explaining the origin of approximately half of the stable nuclei with A > 60, the astrophysical site of this process has not been identified yet. Here we study r-process nucleosynthesis in material that is dynamically ejected by tidal and pressure forces during the merging of binary neutron stars (NSs) and within milliseconds afterwards. For the first time we make use of relativistic hydrodynamical simulations of such events, defining consistently the conditions that determine the nucleosynthesis, i.e., neutron enrichment, entropy, early density evolution and thus expansion timescale, and ejecta mass. We find that 10^{-3}-10^{-2} solar masses are ejected, which is enough for mergers to be the main source of heavy (A > 140) galactic r-nuclei for merger rates of some 10^{-5} per year. While asymmetric mergers eject 2-3 times more mass than symmetric ones, the exact amount depends weakly on whether the NSs have radii of ~15 km for a "stiff" nuclear equation of state (EOS) or ~12 km for a "soft" EOS. R-process nucleosynthesis during the decompression becomes largely insensitive to the detailed conditions because of efficient fission recycling, producing a composition that closely follows the solar r-abundance distribution for nuclei with mass numbers A > 140. Estimating the light curve powered by the radioactive decay heating of r-process nuclei with an approximative model, we expect high emission in the B-V-R bands for 1-2 days with potentially observable longer duration in the case of asymmetric mergers because of the larger ejecta mass.

description: We discuss unreported transitions of oxidized GaAs surfaces between (super)hydrophilic and hydrophobic states when stored in ambient conditions. Contact angles higher than 90deg and high adhesive force were observed for several air-aged epitaxial samples grown under different conditions as well as on epi-ready wafers. Regardless of the morphologies of the surface, superhydrophilicity of oxygen-plasma treated samples was observed, an effect disappearing with storage time. Reproducible hydrophobicity was likewise observed, as expected, after standard HCl surface etching. The relation between surface oxides and hydrophobic/hydrophilic behavior is discussed.

description: Gasification is the thermochemical conversion of a carbon-based fuel into a combustible product gas (syngas) using a gasifying agent, such as steam, carbon dioxide (CO2) or a combination of both. The application of this technology is limited, due to its slow reaction rate, making kinetics determination one of the most active research topics in this field. Different kinetic models have been proposed in the literature for the study of coal and biomass gasification, based on assumptions about their reaction mechanisms. Consequently, a thorough understanding of gasification mechanisms and the validity of these accepted assumptions is necessary to align theoretical studies and industrial results. A maximum rate is typically observed when the experimental gasification rates are plotted against conversion. The scientific community considers this to be an inherent part of the reaction mechanism, associated specifically with char surface changes. It is proven here that the stated maximum rate is a consequence of the reaction gas concentration development. Moreover, the increase in time for which the sample is held in an inert atmosphere reduces the char mesopore area, thereby reducing the char reactivity. As a result of the non-existence of a maximum gasification rate associated with changes in the char surface, kinetic modeling can be simplified. The active char surface area (based on its carbon content) and the amount of catalyst (related to the char alkali content) are the most important variables affecting char reactivity. A new semi-empirical equation correlating these two variables has been developed to estimate gasification rate constants of raw coal and their mixtures for a broad range of ash contents. The selection of a kinetic model mathematically affects the estimation of the kinetic parameters, i.e. activation energy and frequency factor. Therefore, a validation tool for kinetic models is the comparison of their kinetic parameters with those estimated independent of a kinetic model. A new theoretical approach to estimate kinetic parameters independent of a kinetic model for batch experiments has been derived and evaluated for coal gasification. The method can be extended to any chemical reaction and is, therefore, a contribution to chemical reaction engineering fundamentals. The assumption of no mass transfer limitations has been studied at temperatures lower than 900°C. It has been proven that steam gasification rates from most literature reports are limited by interparticle diffusion. A new experimental gasification procedure with negligible mass transfer limitations that do not induce a maximum rate has been developed, providing an alternative for more accurate kinetic studies.

description: We numerically study the effect of adding quenched disorder in the form of randomly placed pinning sites on jamming transitions in systems that jam at a well defined point J in the clean limit. Quenched disorder decreases the jamming density and introduces a depinning threshold. The onset of a finite threshold coincides with point J at the lowest pinning densities, but for higher pinning densities there is always a finite threshold even well below jamming. We find that proximity to point J strongly affects the transport curves and noise fluctuations, and observe a change from plastic behavior below jamming, where the system is highly heterogeneous, to elastic depinning above jamming. Many of the general features we find are related to other systems containing quenched disorder, including the peak effect observed in vortex systems.

description: The utilization and demand of self-medication with herbomineral-based formulations have increased day-by-day across the globe over the last decade. A new proprietary herbomineral formulation was prepared with the mixture of minerals (zinc, magnesium, and selenium) and the herbal root extract of ashwagandha. The current study was undertaken to evaluate the Biofield Energy Healing (The Trivedi Effect®) on the test herbomineral formulation using murine dendritic cells (DCs) and splenocytes in vitro. The formulation was divided into two parts, one part was control without any Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely from eighteen renowned Biofield Energy Healers. The effect of the Biofield Energy Treated formulation in murine cells was monitored with an estimation of pro-inflammatory cytokines levels such as tumor necrosis factor (TNF-α), macrophage inflammatory protein-1α (MIP-1α) and interleukin (IL-1β) in cell culture supernatants along with estimations of non-cytotoxic concentrations of the test formulation by MTT assay. The Biofield Treated formulation showed 114.2%, 122.6%, 141.2%, 127.8%, and 114.1% cell viability at concentrations 1.05, 5.2, 10.5, 25.6, and 51.2 µg/mL, respectively in DCs. Similarly, the Biofield Energy Treated and untreated formulations showed more than 100% cell viability in mice splenocytes at 5 µg/mL. The level of TNF-α in DCs was significantly (p≤0.05) inhibited by 19.21% in the Biofield Treated formulation at concentration 5.2 µg/mL as compared to the untreated test formulation. The level of MIP-1α in LPS induced mice splenocyte cells was reduced by 15.35% in the Biofield Energy Treated formulation at 0.0105 µg/mL as compared to the untreated formulation. Similarly, the level of IL-1β in LPS induced mice splenocyte cells was significantly (p≤0.05) reduced by 31.59% in the Biofield Treated formulation at 1.05 µg/mL as compared to the untreated formulation. Altogether, the results suggest that The Trivedi Effect® (Biofield Energy Healing Treatment) showed significant down-regulation of the tested pro-inflammatory cytokines expression and potentiated the immunosuppressive effect of the treated formulation to modulate the immune system. These data also suggest that the Biofield Treated test formulation can be used for autoimmune and inflammatory diseases, stress management and anti-aging by improving overall health.

description: We propose the evanescent-mode-sensing methods to probe the electrodynamics (QED) vacuum polarization. From our methods, high-sensitivity can be achieved even though the external field is much smaller than the Schwinger critical field and may be realizable in contemporary experimental conditions. The methods are based on the effect of phase change and time delay of evanescent wave which is transmitted in QED vacuum. These methods can also be widely used in sensitive probing of tiny dissipation in other fields.

description: Wastewater treatment plants face unique challenges for process control due to their complex dynamics, slow time constants, and stochastic delays in observations and actions. These characteristics make conventional control methods, such as Proportional-Integral-Derivative controllers, suboptimal for achieving efficient phosphorus removal, a critical component of wastewater treatment to ensure environmental sustainability. This study addresses these challenges using a novel deep reinforcement learning approach based on the Soft Actor-Critic algorithm, integrated with a custom simulator designed to model the delayed feedback inherent in wastewater treatment plants. The simulator incorporates Long Short-Term Memory networks for accurate multi-step state predictions, enabling realistic training scenarios. To account for the stochastic nature of delays, agents were trained under three delay scenarios: no delay, constant delay, and random delay. The results demonstrate that incorporating random delays into the reinforcement learning framework significantly improves phosphorus removal efficiency while reducing operational costs. Specifically, the delay-aware agent achieved 36% reduction in phosphorus emissions, 55% higher reward, 77% lower target deviation from the regulatory limit, and 9% lower total costs than traditional control methods in the simulated environment. These findings underscore the potential of reinforcement learning to overcome the limitations of conventional control strategies in wastewater treatment, providing an adaptive and cost-effective solution for phosphorus removal.
