description: This article discusses the poparms command, which implements two semiparametric estimators for multivalued treatment effects discussed in Cattaneo (2010, Journal of Econometrics 155: 138–154). The first is a properly reweighted inverse-probability weighted estimator, and the second is an efficient-influence function estimator, which can be interpreted as having the double-robust property. Our implementation jointly estimates means and quantiles of the potential outcome distributions, allowing for multiple, discrete treatment levels. These estimators are then used to estimate a variety of multivalued treatment effects. We discuss pre- and postestimation approaches that can be used in conjunction with our main implementation. We illustrate the program and provide a simulation study assessing the finite-sample performance of the inference procedures.

description: In this article, we describe a suite of commands that enable the user to estimate the probability that the conclusions of a meta-analysis will change with the inclusion of a new study, as described previously by Sutton et al. (2007, Statistics in Medicine 26: 2479–2500). Using the metasim command, we take a simulation approach to estimating the effects in future studies. The method assumes that the effect sizes of future studies are consistent with those observed previously, as represented by the current meta-analysis. Two-arm randomized controlled trials and studies of diagnostic test accuracy are considered for a variety of outcome measures. Calculations are possible under both fixed- and random-effects assumptions, and several approaches to inference, including statistical significance and limits of clinical significance, are possible. Calculations for specific sample sizes can be conducted (by using metapow). Plots, akin to traditional power curves, can be produced (by using metapowplot) to indicate the probability that a new study will change inferences for a range of sample sizes. Finally, plots of the simulation results are overlaid on extended funnel plots by using extfunnel, described in Crowther, Langan, and Sutton (2012, Stata Journal 12: 605–622), which can help to intuitively explain the results of such calculations of sample size. We hope the command will be useful to trialists who want to assess the potential impact new trials will have on the overall evidence base and to meta-analysts who want to assess the robustness of the current meta-analysis to the inclusion of future data.

Lectotype ♂ in EMEC (Carriker 1957: 97).
 Type host: Certhidea olivacea olivacea Gould, 1837.
 Galápagos hosts: Pyrocephalus rubinus nanus Gould, 1839; Certhidea olivacea olivacea Gould, 1837.
Galápagos localities: Isla Pinta; Isla Isabela.

Material examined: 6 males, 8 females and 6 nymphs (3 samples, EMEC, MONZ).
 Remarks: From the Kellogg Collection, we examined the lectotype male and five paralectotypes of Docophorus insulicola. Kellogg & Kuwana (1902) reported three passerine hosts for this louse species, including the two hosts given above and Geospiza fuliginosa. Carriker (1957: 97) designated the male lectotype from Certhidea olivacea arguing that specimens from Pyrocephalus rubinus (as Pyrocephalus intercedens) and Geospiza fuliginosa “must be considered as ‘stragglers’ from Certhidea, the true host”, and that additional Philopterus females from Pyrocephalus rubinus were “very different from Kellogg’s figure of insulicola ”. We agree with Carriker (1957) in that Geospiza fuliginosa is not a natural host for Philopterus insulicola. However, we disagree with Carriker’s (1957) statement that Pyrocephalus rubinus is not a natural host for Ph. insulicola because we have identified four males and four females, collected by the 1992 Galápagos Expedition from Pyrocephalus rubinus, as Philopterus insulicola. Furthermore, we are unable to confirm Certhidea olivacea as a natural host for this louse because we did not collect any louse from our examination of six birds of this species. Price et al. (2003: 214) incorrectly listed the three original passerine hosts of Philopterus insulicola as type hosts, not realising that Carriker’s (1957) designation of a lectotype had made Certhidea olivacea the only type host.

description: Reliable and accurate mapping techniques that translate health-related quality-of-life data into EQ-5D index values are now in demand by researchers conducting economic evaluation of health care technologies. In this article, we present two commands (mrs2eq and oks2eq) that translate data from two widely used disease-specific instruments into EQ-5D index values and predicted probabilities of being at a particular level on each EQ-5D domain. mrs2eq conducts a response mapping approach to transform data from the stroke-specific modified Rankin scale into index values from the generic quality-of-life EQ-5D instrument. oks2eq uses a response mapping model to estimate EQ-5D index values based on patients’ responses to the Oxford Knee Score.

description: Many experimental results, both in-vivo and in-vitro, support the idea that the brain cortex operates near a critical point, and at the same time works as a reservoir of precise spatio-temporal patterns. However the mechanism at the basis of these observations is still not clear. In this paper we introduce a model which combines both these features, showing that scale-free avalanches are the signature of a system posed near the spinodal line of a first order transition, with many spatio-temporal patterns stored as dynamical metastable attractors. Specifically, we studied a network of leaky integrate and fire neurons, whose connections are the result of the learning of multiple spatio-temporal dynamical patterns, each with a randomly chosen ordering of the neurons. We found that the network shows a first order transition between a low spiking rate disordered state (down), and a high rate state characterized by the emergence of collective activity and the replay of one of the stored patterns (up). The transition is characterized by hysteresis, or alternation of up and down states, depending on the lifetime of the metastable states. In both cases, critical features and neural avalanches are observed. Notably, critical phenomena occur at the edge of a discontinuous phase transition, as recently observed in a network of glow lamps.

description: We introduce a deterministic model for scale-free networks, whose degree distribution follows a power-law with the exponent $γ$. At each time step, each vertex generates its offsprings, whose number is proportional to the degree of that vertex with proportionality constant m-1 (m>1). We consider the two cases: first, each offspring is connected to its parent vertex only, forming a tree structure, and secondly, it is connected to both its parent and grandparent vertices, forming a loop structure. We find that both models exhibit power-law behaviors in their degree distributions with the exponent $γ=1+\ln (2m-1)/\ln m$. Thus, by tuning m, the degree exponent can be adjusted in the range, $2

description: Objective: Tanshinone IIA (TSN) and Tetramethylpyrazine (TMP) were combined in a composite, oil-in-water nanoemulsions (TSN/TMP O/W NEs) was prepared to prolong in vitro and  vivo circulation time, and enhance the bioavailability of TSN. Material and methods: Physicochemical characterization of TSN/TMP O/W NEs was characterized systematically. The in vitro dissolution and in vivo pharmacokinetic experiments of TSN/TMP O/W NEs were also evaluated. Result: A formulation was optimized, yielding a 32.5 nm average particle size, an encapsulation efficiency of over 95 %, and were spherical in shape as shown by TEM. TSN/TMP O/W NEs were shown to extend the release and availability in vitro compared to raw compounds. In pharmacokinetic study, the AUC0→∞ and t1/2 of the TSN/TMP O/W NEs were 481.50 mg/L*min and 346.39 min higher than TSN solution, respectively. Brain tissue concentration of TSN was enhanced with TSN/TMP O/W NEs over raw TSN and even TSN O/W NEs. Conclusions: Therefore, nanoemulsions are an effective carrier to increase encapsulation efficiency of drugs, improve bioavailability and brain penetration for TSN – which is further enhanced by pairing with the co-delivery of TMP, providing a promising drug delivery.

description: Cold collisions serve as a very sensitive probe of the interaction potential. In the recent study of Klein et al. (Nature Phys. 13, 35-38 (2017)) the one-parameter scaling of the interaction potential was necessary to obtain agreement between theoretical and observed patterns of the orbiting resonances for excited metastable helium atoms colliding with hydrogen molecules. Here we show that the effect of nonrigidity of the H$_2$ molecule on the resonant structure, absent in the previous study, is critical to predict correct positions of the resonances in that case. We have complemented the theoretical description of the interaction potential and revised reaction rate coefficients by proper inclusion of the flexibility of the molecule. The calculated reaction rate coefficients are in remarkable agreement with the experimental data without empirical adjustment of the interaction potential. We have shown that even state-of-the-art calculations of the interaction energy cannot ensure agreement with the experiment if such an important physical effect as flexibility of the interacting molecule is neglected. Our findings about the significance of the nonrigidity effects can be especially crucial in cold chemistry, where the quantum nature of molecules is pronounced.
Impact of Oil Prices on Stock Markets: Evidence from Gulf Cooperation Council (GCC) Financial Markets
Creators: name: Alhaiki, Ahmad
Publisher: name: American University of Bahrain
Year: 2024
Subjects: classificationCode: 38
subject: Economics

description: Being primary exporters and suppliers of oil in the world, and being oil-dependent economies for decades, GCC countries are very likely to be affected by any changes or shocks in oil prices. The effect of oil price turbulences is obvious in stock markets in the long run. Since, there is a correlation between oil price and the stock markets in many oil-producing countries; this study tries to investigate this correlation in GCC countries as major oil producers and exporters. The study aims to evaluate the impact of oil price change in GCC countries in the short and long term, to assess the consequences of the change of stock market prices as a result of oil price change in GCC countries and to examine the influence of stock price change on the local economies of GCC countries. The methodology utilized to achieve the study objectives is the Auto Regressive Distributive Lag Model (ARDL) to analyze monthly stock market and oil price data from November 2006 to February 2015. This study targets all GCC countries: Kuwait Bahrain, Qatar, Oman, KSA and UAE. Unlike all the studies performed on earlier periods, the findings of this study show that there is no evidence for cointegration between oil prices and stock markets in all GCC countries except for Oman where co-integration proved to exist. On the other hand, the results prove that there is a short-run relationship between oil prices and stock market prices.

The initial functions of the MOI were threefold: news and press censorship; home publicity; and oversees publicity in Allied and neutral countries”. This collection contains Press Notices and Bulletins published by the MOI between 1939-1945. The Press Notices and Bulletins are among many publications and films issued by the agency during the war.

description: Recent detection of superflares on solar-type stars by Kepler mission raised a possibility that they can be associated with energetic coronal mass ejections (CMEs) and energetic particle events (SEPs). These space weather events can impact habitability of exoplanets around these stars. Here we use the improved Particle Acceleration and Transport in the Heliosphere (iPATH) model, to model the time intensity profile and spectrum of SEPs accelerated at CME-driven shocks from stars of different ages traced by their rotation rates. We consider a solar-like (G-type) star with 6 different rotation rates varying from 0.5 to 3.0 times rotation speed of the sun. In all 6 cases, a fast CME is launched with the same speed of 1500 km/sec and the resulting time intensity profiles at 3 locations and and energy spectra at 5 locations at 1 AU are obtained. The maximum particle energy at the shock front as a function of r is also shown. Our results suggest that within 0.8 AU the maximum particle energy at the shock front increases with the rotation rate of the star. However, event integrated spectra for the five selected locations along the CME path show complicated patterns. This is because the Parker magnetic field for rapidly rotating stars is more tightly winded. Our results can be used in estimating the radiation environments of terrestrial-type exoplanets around solar-type stars.

description: The current observations seem to suggest that the universe has a positive cosmological constant of the order of $H_0^2$ while the most natural value for the cosmological constant will be $L_P^{-2}$ where $L_P = (G\hbar/c^3)^{1/2}$ is the Planck length. This reduction of the cosmological constant from $L_P^{-2} $ to $L_P^{-2}(L_PH_0)^2$ may be interpreted as due to the ability of quantum micro structure of spacetime to readjust itself and absorb bulk vacuum energy densities. Being a quantum mechanical process, such a cancellation cannot be exact and the residual quantum fluctuations appear as the ``small'' cosmological constant. I describe the features of a toy model for the spacetime micro structure which could allow for the bulk vacuum energy densities to be canceled leaving behind a small residual value of the the correct magnitude. Some other models (like the ones based on canonical ensemble for the four volume or quantum fluctuations of the horizon size) lead to an insignificantly small value of $H_0^2(L_PH_0)^n$ with $n=0.5-1$ showing that obtaining the correct order of magnitude for the residual fluctuations in the cosmological constant is a nontrivial task, becaue of the existence of the small dimensionless number $H_0L_P$ .

description: An ongoing chemical investigation on n-BuOH extract of roots and rhizomes of Helleborus thibetanus afforded three new spirostanol glycosides (1–3). Their structures were elucidated by extensive analysis of 1 D, 2 D NMR spectra, together with IR and MS methods and acid hydrolysis. This is the first report of the isolation of spirostanol glycoside with xylose at C-24 of the aglycone in Helleborus.

description: Deep learning is built on the foundational guarantee that gradient descent on an objective function converges to local minima. Unfortunately, this guarantee fails in settings, such as generative adversarial nets, that exhibit multiple interacting losses. The behavior of gradient-based methods in games is not well understood -- and is becoming increasingly important as adversarial and multi-objective architectures proliferate. In this paper, we develop new tools to understand and control the dynamics in n-player differentiable games. The key result is to decompose the game Jacobian into two components. The first, symmetric component, is related to potential games, which reduce to gradient descent on an implicit function. The second, antisymmetric component, relates to Hamiltonian games, a new class of games that obey a conservation law akin to conservation laws in classical mechanical systems. The decomposition motivates Symplectic Gradient Adjustment (SGA), a new algorithm for finding stable fixed points in differentiable games. Basic experiments show SGA is competitive with recently proposed algorithms for finding stable fixed points in GANs -- while at the same time being applicable to, and having guarantees in, much more general cases.

description: Canthin-6-one analogue, 4-methoxy-5-hydroxycanthin-6-one (CAN1) was isolated from Picrasma quassioides (D.Don) Benn., and a series of derivatives containing the CAN1 framework were designed, synthesized, and evaluated for anti-proliferative activity against two human cancer cell lines, HepG2 and HCT116. Among these compounds, the most representative compound d exhibited better anti-proliferative activities in vitro compared with the positive control Fluorouracil (5-FU), with IC50 values of 5.05 μM (HepG2) and 6.65 μM (HCT116), respectively. Compound d triggered more significant HepG2 cell apoptosis than 5-FU did in a dose-dependent manner. Furthermore, western blot assay indicated that d could enhance the expression of p65 while promoting pro-apoptotic proteins and suppressing the anti-apoptotic proteins in a dose-dependent manner. All these results demonstrated that d might be a potential agent for cancer therapy deserving further exploring.

description: We use powder x-ray diffraction to study the effect of pressure on the crystal structure of the honeycomb rhodate Li$_2$RhO$_3$. We observe low-pressure ($P$$$$P_{c2}$ = 14 GPa) regions corresponding to the monoclinic $C2/m$ symmetry, while a phase mixture is observed at intermediate pressures. At $P$$>$$P_{c2}$, the honeycomb structure becomes distorted and features short Rh--Rh bonds forming zigzag chains stretched along the crystallographic $a$ direction. This is in contrast to dimerized patterns observed in triclinic high-pressure polymorphs of $α$-Li$_2$IrO$_3$ and $α$-RuCl$_3$. Density-functional theory calculations at various pressure conditions reveal that the observed rhodium zigzag-chain pattern is not expected under hydrostatic pressure but can be reproduced by assuming anisotropic pressure conditions.

 TYPE:  AUSTRALIA: Northern Territory : Male holotype from Calvert Hills Station, 49 km W of Calvert Road turnoff, 16 ° 49 9 23 0 S, 137 ° 08 9 57 0 E, 150 m (6 July–14 Sep. 2006, R. Raven, B. Baehr, A. Amey) (PBI_OON 00006104), deposited in QM (S75164).
ETYMOLOGY: The specific name is a patronym in honor of Noela Helene Shepherd.
 DIAGNOSIS: Males of C. noelashepherdae resemble those of C. ewani, with the sternal concavity occupying most of the sternal length (fig. 22). However, males of C. noelashepherdae can be easily separated from all other species by their greatly reduced fangs (fig. 22), the endites with medially directed triangular lobes (fig. 22) and the row of stiff setae near the anterior margin of the clavate field (fig. 22).
MALE: Total length 0.99. Carapace 0.49 long, 0.37 wide; abdomen 0.50 long, 0.29 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum longer than wide, median concavity occupying most of sternal length, with field of clavate setae covering about half of sternum width, median band bare, anterior margin with rectangular rim of short, stiff setae (fig. 22). Chelicerae straight, fang directed medially, reduced, tip unmodified. Endites with medially directed triangular lobes. Abdomen ovoid, epigastric scutum slightly protruding; sperm pore surrounded by circular field of pores. Cymbium-bulb complex bearing a long, medially bent embolus with a broadened basis (figs. 158–160).
FEMALE: Unknown.
DISTRIBUTION: This species is known only from Calvert Hills Station in northeastern Northern Territory (map 3).

description: We investigate the sensitivity of observables measurable in e^+ e^-, gamma gamma and mu^+ mu^- collisions for distinguishing the properties of the light neutral CP-even Higgs boson in the minimal supersymmetric extension of the Standard Model (MSSM) from those of a Standard Model (SM) Higgs boson with the same mass. We explore first the available parameter space in the constrained MSSM (CMSSM), with universal soft supersymmetry-breaking parameters, incorporating the most recent direct limits on sparticle and Higgs masses, the indirect constraints from b to s gamma and g_mu - 2, and the cosmological relic density. We calculate the products of the expected CMSSM Higgs production cross sections and decay branching ratios sigma X B normalized by the corresponding values expected for those of a SM Higgs boson of the same mass. The results are compared with the precisions expected at each collider, and allow for a direct comparison of the different channels. The measurements in the Higgs sector are found to provide important consistency tests of the CMSSM. We then generalize our analysis to the case of a non-universal Higgs model (NUHM), where the values of M_A and mu are independent parameters. We explore in particular the sensitivity to M_A, finding that measurements at e^+ e^-, gamma gamma and mu^+ mu^- colliders could yield indirect constraints on its value, up to M_A ~ 1200 GeV. We discuss the potential of these measurements for distinguishing between the CMSSM and the NUHM, probing in this way the assumption of universality.

description: We develop {\it ab initio} relativistic QED theory for elastic electron scattering on hydrogen-like highly charged ions for impact energies where, in addition to direct (Coulomb) scattering, the process can also proceed via formation and consequent Auger decay of autoionizing states of the corresponding helium-like ions. Even so the primary goal of the theory is to treat electron scattering on highly charged ions, a comparison with experiment shows that it can also be applied for relatively light ions covering thus a very broad range of the scattering systems. Using the theory we performed calculations for elastic electron scattering on B$^{4+}$, Ca$^{19+}$, Fe$^{25+}$, Kr$^{35+}$, and Xe$^{53+}$. The theory was also generalized for collisions of hydrogen-like highly charged ions with atoms considering the latter as a source of (quasi-) free electrons.
