The dynamic calibration of an electrical capacitance tomography sensor applied to the fluidized bed drying of pharmaceutical granule

Electrical capacitance tomographic data collected in a lab-scale fluidized bed used for the drying of pharmaceutical granule have been corrected for the influence of moisture on the permittivity of the drying material. The correction is based on a linear least-squares fit to measurements of capacitance in a packed bed of granule at various moisture contents. X-ray tomography has been used to independently verify this correction procedure. The influence of permittivity models and number of iterations used for the reconstruction of tomograms have also been examined. It has been determined that the Böttcher permittivity model performs best at bed moistures above approximately 5 wt% while the parallel model is superior at bed moisture below this value. The reconstruction technique based on iterative linear back-projection utilized for the reconstruction of ECT data required approximately 50 iterations to successfully reproduce the density behaviour seen in the x-ray tomographs. Instability in the reconstruction technique at higher numbers of iterations indicates that a linear least-squares fit does not completely capture the response of the sensor to moisture changes. For future applications, changes in bed voidage associated with the drying of pharmaceuticals must be addressed and included in this calibration procedure in order to implement this calibration technique throughout the drying process. Nevertheless, the viability of this technique for on-line calibration of an ECT sensor applied to the drying process has been demonstrated.
Transient eddy current calculation using magnetic vector potential method combined with incomplete tree gauge

An incomplete tree gauge for 3D transient eddy current computation using edge elements is presented. The proposed formulation is compared with the non-gauged and the random tree gauged formulations, showing that it results in better precision and better system matrix conditioning. H circulation is used to calculate the transient eddy current density. The results of the different approaches are discussed.
Stability and dynamic properties of multi-electrode laser diodes using a Green's function approach

In DFB (distributed feedback) lasers, the shape of the longitudinal intensity and carrier density distributions changes above threshold as a result of spatial hole burning. The longitudinally distributed coupling of spontaneous emission into the lasing mode also plays an important role for the noise properties. The authors demonstrate how both effects can be included in a dynamic analysis. They extend their previously developed theory for multielectrode lasers to enable calculation of stability properties as well as small-signal modulation responses and noise spectra. The theory is used to study global and local stability of the stationary solutions (modes). The numerical results for several laser structures are presented. It is shown that symmetric DFB lasers are likely to exhibit pitchfork bifurcations in their static tuning characteristics as the current is increased. The authors discuss how the presence or proximity of such instabilities can affect the modulation and noise properties, and in particular, the spectral linewidth. >
Bar fraction in lenticular galaxies: dependence on luminosity and environment

We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) and Two-Micron All-Sky Survey in the optical and near-infrared bands, respectively. We found a bar in 15 per cent of the lenticular galaxies in our sample, which is consistent with recent studies. The barred galaxy fraction shows a luminosity dependence, with faint lenticular galaxies (MK > −24.5, total absolute magnitude in the K band) having a larger fraction of bars than bright lenticular galaxies (MK < −24.5). A similar trend is seen when Mr=−21.5, the total absolute magnitude in the SDSS r band, is used to divide the sample into faint and bright lenticular galaxies. We find that faint galaxies in clusters show a higher bar fraction than their counterparts in the field. This suggests that the formation of bars in lenticular galaxies not only depends on the total luminosity of the galaxy, but also depends on the environment of the host galaxy.

Parameters which characterize these three basic qualities include (1) [O III] λ5007 emission line widths measured at various levels in the profile, (2) galaxy luminosity, morphology, inclination, disturbance, and rotation amplitude, and (3) Hβ luminosity, [O III] h5007 luminosity, radio luminosity, radio morphology, and Seyfert type
Polyethylene Glycol and Sorbitol-Mediated In Vitro Screening for Drought Stress as an Efficient and Rapid Tool to Reach the Tolerant Cucumis melo L. Genotypes

An efficient method to instantly assess drought-tolerant plants after germination is using osmoregulation in tissue culture media. In this study, the responses of three Iranian melon genotypes to sorbitol (0.1, 0.2, and 0.4 M) or polyethylene glycol (PEG) (0.009, 0.012, and 0.015 M) were evaluated as drought stress simulators in MS medium. ‘Girke’ (GIR), ‘Ghobadloo’ (GHO), and ‘Toghermezi’ (TOG) were the genotypes. GIR is reputed as a drought-tolerant genotype in Iran. The PEG or sorbitol decreased the coleoptile length, fresh weight, and photosynthetic pigments content while enhancing proline and malondialdehyde (MDA) contents. Protein content and antioxidant enzyme activity were utterly dependent on genotype, osmotic regulators, and their concentration. Coleoptile length, root and shoot fresh weight, root dry weight, proline and MDA content, and guaiacol peroxidase (GPX) activity can be used as indicators for in vitro screening of Cucumis melo L. genotypes. The results showed that sorbitol mimics drought stress better than PEG. Overall, our findings suggest that in vitro screening could be an accurate, rapid, and reliable methodology for evaluating and identifying drought-tolerant genotypes.
Trend followers lose more often than they gain

We solve exactly a simple model of trend following strategy, and obtain the analytical shape of the profit per trade distribution. This distribution is non trivial and has an option like, asymmetric structure. The degree of asymmetry depends continuously on the parameters of the strategy and on the volatility of the traded asset. While the average gain per trade is always exactly zero, the fraction f of winning trades decreases from f = 1/2 for small volatility to f = 0 for high volatility, showing that this winning probability does not give any information on the reliability of the strategy but is indicative of the trading style.
Simulations of ring current proton pitch angle distributions

We employ a three-dimensional ring current model to trace the bounce-averaged drift of singly charged ions during storm-associated enhancements in the convection electric field. Using the simulation results, we map proton phase space density during the main and recovery phases of a storm in accordance with conservation of phase space density ƒ. We map from an initial quiescent phase space distribution that is obtained by solving the steady state transport equation (bounce-averaged charge exchange balancing bounce-averaged radial diffusion) with observed plasma sheet proton spectra as outer boundary conditions. We obtain proton pitch angle distributions at L ∼ 3–4.5 by evaluating ƒ at representative ring current energies (∼20–170 keV). We find that the prestorm and stormtime proton pitch angle anisotropy at any given L between 3 and 4.5 increases with particle energy in agreement with observations. The actual anisotropy at specific energies depends strongly on the shape of the plasma sheet source spectrum at ∼0.5–3 keV. Relatively large enhancements in the stormtime phase space density from the quiescent distribution occurs at all pitch angles for low energies (≲80 keV) except where the quiescent distribution lies on open drift shells. These increases result primarily from stormtime access to L ≲ 4.5 along open drift trajectories from the plasma sheet. For higher-energy (≳150 keV) protons, which are transported via radial diffusion, there is little change in the anisotropy over a 3-hour storm. At intermediate energies (E ∼ 80–150 keV) the stormtime enhancements in the phase space density can vary quite strongly with equatorial pitch angle. For such particles the stormtime transport is intermediate between directly convective and quasi-diffusive, which can complicate the analysis of stormtime pitch angle anisotropies at intermediate energies. Decay lifetimes obtained from CRRES data during the recovery phase of a moderate storm are found to be considerably shorter than charge-exchange lifetimes. It thus appears that charge exchange alone is not enough to explain the observed rapid decay of the proton ring current.
Computational Efficiency through Visual Argument: Do Graphic Organizers Communicate Relations in Text Too Effectively?.

Abstract Previous research on graphic organizers has found that they facilitate memory for corresponding text. This study investigated why one type of graphic organizer (a matrix) may communicate interconcept relations more effectively than an outline or text. In three experiments, college students judged the accuracy of interconcept relations after they read a text and studied a matrix, an outline, or the text again. We also measured students′ performance when study time was reduced and testing delayed. Results indicated that even when study time was reduced, viewing a matrix helped students make more accurate judgments of interconcept relations. We conclude that a matrix is more computationally efficient than an outline or text, enabling readers to compute interconcept relations more quickly and easily (Larkin & Simon, 1987), due to a communicative process called visual argument (Waller, 1981). However, this advantage disappeared when testing was delayed, which, ironically, may have been due to computational efficiency.
Observations of plasmas associated with the magnetic signature of a plasmoid in the distant magnetotail

The three-dimensional electron and positive ion velocity distributions were examined for four events for which the magnetic signature of plasmoids occurred at the Geotail spacecraft position in Earth`s distant magnetotail. The proton bulk parameters and the electron velocity distributions for one of the events are presented in order to characterize the qualitative character of the set of events. The north-to-south turnings of the magnetic field that were taken for evidence of the passage of a plasmoid were often accompanied by a significant strong core of B{sub y} that was centered on the transition of B{sub z} from north to south. The magnetic signatures thus appeared to be more indicative of flux ropes than of classical plasmoids with weak core fields. The proton and electron bulk velocities in these magnetic structures are not equal, a situation that provides an earthward current. The plasma {beta} was typically one or greater. Counterstreaming of low-energy electrons was often found on the magnetic field lines around the central magnetic core and suggested the existence of a closed field line topology in these regions. These events appeared to be the tailward flowing debris from acceleration processes occurring in the vicinity of a separator positioned nearer tomore » Earth. 13 refs., 4 figs.« less
The longitudinal influence of supportive messages on stress reactivity and general well-being for LGBTQ+ recipients of hate speech: Comparing the relative effects of verbal person-centered and autonomy support

ABSTRACT LBGTQ+ individuals (N = 50) engaged in a 10-minute discussion with a close network member about an experience they had with hate speech that was targeted at their sexual orientation. The relative effects of two predominant social support theoretical frameworks, verbal person centeredness and autonomy support, were compared. Discussions were rated by trained raters for the presence of each type of support. Results support both theoretical frameworks as predicting decreases in stress across the discussion as well as increases in reported general well-being over one month. Theoretical implications and methodological comparison are discussed.
Stock Markets’ Reactions to the Announcement of the Hosts. An Event Study in the Analysis of Large Sporting Events in the Years 1976–2032

This study attempts to estimate the impact of the announcements of hosts of large sporting events on domestic stock markets. The research problem is to establish a connection between the uniqueness of a sporting event and investors’ beliefs through stock price behavior. Using appropriate estimation windows, 13 different sporting events classified as large, including mega and major events, were tested. The obtained results show that, in principle, one day after the announcement of the host of a large sporting event, an average positive reaction of 0.22% is observed on national stock exchanges. The analyzed events were also classified as being neutral for capital markets or generating positive or negative reactions when the host country is announced to the public.
Can Serum Fetuin-A be Used as a Marker for Cardiovascular Involvement in Psoriatic Patients?

Background Psoriasis is a systemic inflammatory disorder. It is associated with increased risk of developing other chronic health diseases such cardiovascular disorders. Fetuin A is a glycoprotein that is present in blood serum. It may prevent vascular calcification by forming calciprotien particles; which are formed from their attachment with phosphate and calcium complexes. Aim The aim of this study was to measure serum Fetuin A in Psoriatic patients and correlate its level with cardiac events and risks in these patients using CT calcium (Ca) scoring. Patients and Methods 24 psoriatic patients (healthy without apparent cardiac risks to detect subclinical events if present) and 24 age and sex matched controls were tested for serum Fetuin A and underwent coronary calcium scoring by multidetector computed tomography (CT) scan. Psoriasis area and severity index (PASI) score for each patient was measured and was correlated with serum Fetuin A and CT calcium (Ca) scoring. Serum Fetuin A was compared between cases and controls and was correlated with coronary calcium score. Results There was highly statistically significant decrease in serum Fetuin A level in psoriatic group compared to control group (P-value < .001). There was highly statistically significant negative correlation between calcium score and the level of serum Fetuin A (P-value < .001). No statistically significant correlation was found between the serum level of Fetuin A and the psoriasis severity. Conclusion Serum Fetuin A is a simple, easy diagnostic tool to evaluate subclinical atherosclerosis in psoriatic patients
Obesity-associated cardiometabolic complications in polycystic ovary syndrome: The potential role of sodium-glucose cotransporter-2 inhibitors

Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder in reproductive-age women. PCOS is characterized by androgen excess, oligo/anovulation, and polycystic appearance of the ovaries. Women with PCOS have an increased prevalence of multiple cardiovascular risk factors such as insulin resistance, hypertension, renal injury, and obesity. Unfortunately, there is a lack of effective, evidence-based pharmacotherapeutics to target these cardiometabolic complications. Sodium-glucose cotransporter-2 (SGLT2) inhibitors provide cardiovascular protection in patients with and without type 2 diabetes mellitus. Although the exact mechanisms of how SGLT2 inhibitors confer cardiovascular protection remains unclear, numerous mechanistic hypotheses for this protection include modulation of the renin-angiotensin system and/or the sympathetic nervous system and improvement in mitochondrial function. Data from recent clinical trials and basic research show a potential role for SGLT2 inhibitors in treating obesity-associated cardiometabolic complications in PCOS. This narrative review discusses the mechanisms of the beneficial effect of SGLT2 inhibitors in cardiometabolic diseases in PCOS.
Radiative accelerations in stellar atmospheres

We present calculations of radiative accelerations obtained with the general purpose model atmosphere code PHOENIX. The accelerations are computed simultaneously for all the elements He–Ga; Kr–Nb; Ba; La, using the opacity sampling method. The calculations are mainly performed with the LTE approximation. Tests are made to evaluate the influence of non-LTE effects and the validity of the radiative flux obtained through the diffusion approximation. It is shown that the abundances supported in the atmospheres of HgMn and He-weak stars are generally consistent with those observed.
Magnetoencephalography with a two color pump-probe fiber-coupled atomic magnetometer.

The authors have detected magnetic fields from the human brain with a compact, fiber-coupled rubidium spin-exchange-relaxation-free magnetometer. Optical pumping is performed on the D1 transition and Faraday rotation is measured on the D2 transition. The beams share an optical axis, with dichroic optics preparing beam polarizations appropriately. A sensitivity of <5 fT/Hz is achieved. Evoked responses resulting from median nerve and auditory stimulation were recorded with the atomic magnetometer. Recordings were validated by comparison with those taken by a commercial magnetoencephalography system. The design is amenable to arraying sensors around the head, providing a framework for noncryogenic, whole-head magnetoencephalography.
Finite-time global chaos synchronization for piecewise linear maps

In this paper, sufficient conditions of global synchronization in finite-time, which can be a minimum, are presented for the generic class of piecewise linear maps. The conditions of synchronization are based upon general results of the robust control theory, the observability theory, and the specificity of the chaotic motion generated by the map. The robust control theory results enable global synchronization with disturbances cancellation. Observability and assignment of eigenvalues ensure finite-time synchronization. A systematic methodology for designing a global finite-time synchronization derived from those conditions is presented. From a practical point of view, this only requires classical numerical solvers. Finite-time global synchronization can be of interest for applications such as digital communications.
Impedance variation of a flux-lock type SFCL dependent on winding direction between coil 1 and coil 2

The flux-lock type superconducting fault current limiter (SFCL) uses the magnetic coupling between two coils connected in parallel with each other. This SFCL has the merit that both the resistance of high-T/sub C/ superconducting (HTSC) element and the limiting current capacity can be simultaneously increased through the application of magnetic field into HTSC element. However, unlike other types SFCLs, the different fault current limiting characteristics can appear according to the winding direction between the two coils. In this paper, the relation of the impedance of the flux-lock type SFCL with the resistance of HTSC element was derived from its equivalent circuit using the current and the voltage relationship between the two coils. The limiting impedances of the flux-lock type SFCL due to the winding direction through the discrete fourier transform (DFT) analysis for the voltage and the current data obtained from the fault current limiting experiments were extracted and analyzed from the point of view of the limited line current and the resistance of HTSC element.
Continuum concepts in nanoscale capillary impregnation

The design of tailor-made nanofluidic devices requires an extension of macroscale hydrodynamic theories for capillary impregnation (CI). Large-scale molecular dynamics (MD) simulations of a simple capillary pump consisting of a nanoscale gold slit attached to a liquid propane reservoir reveal that distinct finite-size-effects impact CI on the nanoscale. A continuum theory is derived that captures these finite-size-effects: properties of a prewetting monolayer, a related Navier-slip, nanoscopic contact angles and wall-induced oscillatory pressure fluctuations enter as non-heuristic atomistic input into the derivation of extended lubrication equations that exactly reproduce the capillary rise dynamics and menisci from our MD simulations. It turns out that impregnation in bare nanochannels can be significantly accelerated by the strong slip induced by a spreading precursor. As expected, this effect is absent in micron sized channels, where our extended continuum theory predicts a capillary dynamics that is already insensitive to all nanoscopic details at the contact line.
Cross-Cultural Validation of the Malaysian Mood Scale and Tests of Between-Group Mood Differences

Mood measures have been shown to have utility for monitoring risks to mental health and to predict performance among athletes. To facilitate use in a Malaysian context, we tested a Malay-language version of the 24-item Brunel Mood Scale (BRUMS), referred to as the Malaysian Mood Scale (MASMS). Following a thorough translation–back-translation process, the 24-item MASMS was administered to 4923 Malay-speaking respondents (2706 males, 2217 females; 2559 athletes, 2364 non-athletes), ranging in age from 17 to 75 years (M = 28.2 years, SD = 9.4 years). Confirmatory factor analysis supported the six-factor MASMS measurement model (CFI = 0.950, TLI = 0.940, RMSEA = 0.056 [CI 0.055, 0.058]). Convergent and divergent validity of the MASMS were supported via relationships with depression, anxiety, and stress measures. Significant differences in mood scores were found between athletes and non-athletes, males and females, and younger and older participants. Tables of normative data and profile sheets for specific groups were generated. We propose that the MASMS is a valid measure that can be used to monitor mental health status among athletes and non-athletes and that facilitates future mood-related research in Malaysia.
Intermittent behavior in the transition region and the low corona of the quiet Sun

We present an analysis of light-curves obtained in the O IV and Ne VIII transition region and low corona lines, that were simultaneously recorded in a quiet Sun region by SUMER/SOHO. By using the flatness spectrum of the observed light-curves we searched for intermittency signatures. It was found that a signicant proportion of points in the observed area exhibit clear indications of intermittency, irrespectively of their intrinsic intensity. Our ndings give favor to an impulsively heated transition region and corona via intermittent-type MHD turbulence.
RATGP95: a harmonic development of the tide-generating potential using an analytical method.

SUMMARY A harmonic development of the tide-generating potential (TGP), named RATGP95, has been computed using an analytical method. The lunar part of the potential has been developed to degree five and the solar part to degree three. In addition, we have considered several perturbing effects: direct and indirect planetary effects; lunar inequality; effects of the nutations; Earth’s ffattening; and time dependence of the amplitudes. Finally, we have obtained a tidal potential of 6499 terms that has a truncation level of 2.6 x lop7 m2 s-~ and an accuracy of 1.6 (9.35) ngal in the time domain and 0.003 (1.58) ngal in the frequency domain (1 ngal = lo-’ gal = lo-” m sp2). This has been evaluated by computing the root mean square (maximum) of the differences with respect to the benchmark series bfde200a from Wenzel (1995).
