Symptoms, function and quality of life in myalgic encephalomyelitis/chronic fatigue syndrome : an Australian based, cross-sectional study
Creators: name: Donnelly, K
Publisher: name: University Of Tasmania
Year: 2023

description: Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex condition associated with multiple symptoms, everyday functional impairment and reduced quality of life. However, there is a paucity of published literature on the symptoms associated with everyday functional impairment and quality of life of adults in Australia with ME/CFS. In particular, use of psychometrically tested, disease specific measurement tools is limited. This has implications for understanding the unique symptom presentation of ME/CFS and appropriate clinical management. Aim: To explore the association between symptoms, everyday function and quality of life in a cohort of adult Australians with ME/CFS. Objectives: 1) To describe participants demographic characteristics 2) To explore symptoms (using the ME/CFS specific DePaul Symptom Questionnaire (DSQv1) and their association with everyday function and quality of life (using the generic Medical Outcomes 36-item Short Form Health Survey (SF-36) in adults who meet the Institute of Medicine clinical diagnostic criteria for ME/CFS. Method: A cross-sectional sample was obtained from respondents to advertisements on social media, support organisation websites and newsletters. Descriptive statistics were obtained on demographics, symptom scores and everyday function and quality of life. Symptom domains were created from the DSQv1. Associations between symptom domains, everyday function and quality of life were examined using Spearman's correlations. Results: One hundred and fifty-six respondents met the Institute of Medicines clinical diagnostic criteria. The majority of respondents were female (88.5%) and highly educated. In all, 51 (32.7%) were in paid employment and 105 (67.3%) were not in paid employment. All symptom domains had a significant, negative association with the Physical Component Summary of the SF-36 at the p = 0.01 level. The symptom domains with the strongest negative association were post-exertional malaise (Rs = -.596), fatigue (Rs -.539) and pain (Rs = -.506). Conclusion: This Australian study found that post-exertional malaise, fatigue and pain have a strong negative association with everyday function and quality of life in adults with ME/CFS. These findings support local and international literature on the importance of multisymptomatic management of ME/CFS. It also supports investigating the everyday functional limitations of patients and how they perceive their QoL to develop better measurement tools and instigate appropriate supports. Due to the high levels of unemployment in this study, the health economic implications of ME/CFS are of high priority for further study.

description: Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their chemical enrichment. In this paper we investigate azimuthal variations of abundances in the Milky Way using Cepheids. We provide the detailed chemical composition (25 elements) of 105 Classical Cepheids from high-resolution SALT spectra observed by the MAGIC project. Negative abundance gradients, with abundances decreasing from the inner to the outer disc, have been reported both in the Milky Way and in external galaxies, and our results are in full agreement with literature results. We find azimuthal variations of the oxygen abundance [O/H]. While a large number of external spirals show negligible azimuthal variations, the Milky Way seems to be one of the few galaxies with noticeable [O/H] azimuthal asymmetries. They reach ~0.2 dex in the inner Galaxy and in the outer disc, where they are the largest, thus supporting similar findings for nearby spiral galaxies as well as recent 2D chemo-dynamical models.

description: Mobile networks (MN) are anticipated to provide unprecedented opportunities to enable a new world of connected experiences and radically shift the way people interact with everything. MN are becoming more and more complex, driven by ever-increasingly complicated configuration issues and blossoming new service requirements. This complexity poses significant challenges in deployment, management, operation, optimization, and maintenance, since they require a complete understanding and cognition of MN. Artificial intelligence (AI), which deals with the simulation of intelligent behavior in computers, has demonstrated enormous success in many application domains, suggesting its potential in cognizing the state of MN and making intelligent decisions. In this paper, we first propose an AI-powered mobile network architecture and discuss challenges in terms of cognition complexity, decisions with high-dimensional action space, and self-adaption to system dynamics. Then, potential solutions that are associated with AI are discussed. Finally, we propose a deep learning approach that directly maps the state of MN to perceived QoS, integrating cognition with the decision. Our proposed approach helps operators in making more intelligent decisions to guarantee QoS. Meanwhile, the effectiveness and advantages of our proposed approach are demonstrated on a real-world dataset, involving $31261$ users over $77$ stations within $5$ days.

description: We present the first results of our optical spectroscopy program aimed to provide redshifts and identifications for the X-ray sources in the Extended Chandra Deep Field South. A total of 339 sources were targeted using the IMACS spectrograph at the Magellan telescopes and the VIMOS spectrograph at the VLT. We measured redshifts for 186 X-ray sources, including archival data and a literature search. We find that the AGN host galaxies have on average redder rest-frame optical colors than non-active galaxies, and that they live mostly in the "green valley". The dependence of the fraction of AGN that are obscured on both luminosity and redshift is confirmed at high significance and the observed AGN space density is compared with the expectations from existing luminosity functions. These AGN show a significant difference in the mid-IR to X-ray flux ratio for obscured and unobscured AGN, which can be explained by the effects of dust self-absorption on the former. This difference is larger for lower luminosity sources, which is consistent with the dust opening angle depending on AGN luminosity.

description: Climate policies can target either the demand or the supply of fossil fuels. While demand-side policies have been analyzed in the literature and applied in policy-making, supply-side policies, e.g. deposit policies, are a promising option and a recent research focus. In this paper we study deposit markets for two fuels that differ in emission intensity. We find that, with strategic action on the deposit markets, deposit policies are inefficient due to price manipulations within and between both deposit markets. Regarding the political economy of deposit policies, they generate more welfare for all countries if applied to both fuels as opposed to one or none. Further, for perfectly segmented fuel markets, importing countries do not purchase deposits of a sufficiently clean fuel. If fuels are substitutes and strongly differ in emission intensity, countries do not buy deposits of a relatively clean fuel. Finally, deposit markets can induce countries selling deposits to choose a cleaner fuel mix.

Secondary slip of screw dislocations in zirconium
Creators: name: Maras, Émile
name: Clouet, Emmanuel
Publisher: name: arXiv
Year: 2021
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Plasticity in hexagonal close-packed zirconium is controlled by screw dislocations which easily glide in the prismatic planes where they are dissociated. At high enough temperatures, these dislocations can deviate out of the prism planes to also glide in the first order pyramidal and basal planes. To get a better understanding of these secondary slip systems, we have performed molecular dynamics (MD) simulations of a screw dislocation gliding in a basal plane. The gliding dislocation remains dissociated in the prism plane where it performs a random motion and occasionally cross-slips out of its habit plane by the nucleation and propagation of a kink-pair. Deviation planes are always pyramidal, with an equal probability to cross-slip in the two pyramidal planes on both sides of the basal plane, thus leading to basal slip on average. Basal slip appears therefore as a combination of prismatic and pyramidal slip in the high stress regime explored in MD simulations. This is confirmed by nudged elastic band (NEB) calculations. But NEB calculations also reveal a change of glide mechanism for a decreasing applied stress. At low stress, kinks do not lie anymore in the pyramidal planes. They are now spread in the basal planes, thus fully compatible with a motion of the screw dislocation confined to the basal plane as seen in experiments. Basal slip, which is in competition with pyramidal slip, appears therefore favoured at low stress in pure zirconium.

description: The treatment of dust attenuation is crucial in order to compare the predictions of galaxy formation models with multiwavelength observations. Most past studies have either used simple analytic prescriptions or else full radiative transfer (RT) calculations. Here, we couple star formation histories and morphologies predicted by the semi-analytic galaxy formation model MORGANA with RT calculations from the spectrophotometric and dust code GRASIL to create a library of galaxy SEDs from the UV/optical through the far Infrared, and compare the predictions of the RT calculations with analytic prescriptions. We consider a low and high redshift sample, as well as an additional library constructed with empirical, non-cosmological star formation histories and simple (pure bulge or disc) morphologies. Based on these libraries, we derive fitting formulae for the effective dust optical depth as a function of galaxy physical properties such as metallicity, gas mass, and radius. We show that such fitting formulae can predict the V-band optical depth with a scatter smaller than 0.4 dex for both the low and high redshift samples, but that there is a large galaxy-to-galaxy scatter in the shapes of attenuation curves, probably due to geometrical variations, which our simple recipe does not capture well. However, our new recipe provides a better approximation to the GRASIL results at optical wavelength than standard analytic prescriptions from the literature, particularly at high redshift.

description: Let K be a d-dimensional convex body, and let $K^{(n)}$ be the intersection of n halfspaces containing $K$ whose bounding hyperplanes are independent and identically distributed. Under suitable distributional assumptions, we prove an asymptotic formula for the expectation of the difference of the mean widths of $K^{(n)}$ and K, and another asymptotic formula for the expectation of the number of facets of $K^{(n)}$. These results are achieved by establishing an asymptotic result on weighted volume approximation of $K$ and by "dualizing" it using polarity.

description: The great diversity of end-user tasks ranging from manufacturing environments to personal homes makes pre-programming robots for general purpose applications extremely challenging. In fact, teaching robots new actions from scratch that can be reused for previously unseen tasks remains a difficult challenge and is generally left up to robotics experts. In this work, we present iRoPro, an interactive Robot Programming framework that allows end-users with little to no technical background to teach a robot new reusable actions. We combine Programming by Demonstration and Automated Planning techniques to allow the user to construct the robot's knowledge base by teaching new actions by kinesthetic demonstration. The actions are generalised and reused with a task planner to solve previously unseen problems defined by the user. We implement iRoPro as an end-to-end system on a Baxter Research Robot to simultaneously teach low- and high-level actions by demonstration that the user can customise via a Graphical User Interface to adapt to their specific use case. To evaluate the feasibility of our approach, we first conducted pre-design experiments to better understand the user's adoption of involved concepts and the proposed robot programming process. We compare results with post-design experiments, where we conducted a user study to validate the usability of our approach with real end-users. Overall, we showed that users with different programming levels and educational backgrounds can easily learn and use iRoPro and its robot programming process.

Creators: name: Adamson, Robert D.
Publisher: name: Utah State University

description: Fluvial and lacustrine sediments of great thickness accumulated in the intermountain basins of the western United States during Tertiary time. The Salt Lake group in northern Utah and parts of surrounding states is a conspicuous stratigraphic unit of these basins. The "beds of light color" in Morgan Valley in the Wasatch Mountains of northern Utah were named the "Salt Lake group" by Hayden (1869) because of similar occurrences in Salt Lake Valley and because he reasoned that the succession could be divided into formations. Similar rocks crop out in Ogden Valley, north of Morgan Valley, and in Cache Valley, Utah and Idaho. Cache Valley is bounded by the Wasatch and Malad Ranges to the west and the Bear River Range to the east (Fig. 1). It extends from the divide between Ogden and Cache valleys about 18 miles south of Los an. Utah. to Red Rock Pass. about 19 miles northwest of Preston. Idaho. The Bear River enters Cache Valley northeast of Preston. Idaho. and leaves through the Bear River Narrows west of Logan. Utah. at a point between the northern end of the Wasatch Range and the Malad Range. Red Rock Pass, northwest of Preston, Idaho, was the outlet of Lake Bonneville.

The three dimensional structure of Batholiths as deduced from gravity data
Creators: name: Ager, Charles Arthur
Publisher: name: University of British Columbia
Year: 2010

description: The intent of the work presented here is to interpret the three dimensional structure of batholiths from gravity data. The batholiths studied were the Guichon Creek, Hogem and Iron Mask batholiths located in the central, interior of British Columbia and within the Canadian Western Cordillera. Despite their gross geological differences, these batholiths have a remarkably similar three dimensional shape. After correlating gross shape with existing theories of batholith emplacement, a new theory for the emplacement of these batholiths has been proposed. This 'tectonic injection' theory is intended to apply to all batholiths that fall within the class of "funnel-type". As a corollary, ideas are also presented on the significance of the spatial correlation of mineral occurrances with gross shape.

description: Symmetry underpins our understanding of physical law. Open systems, those in contact with their environment, can provide a platform to explore parity-time symmetry. While classical parity-time symmetric systems have received a lot of attention, especially because of the associated advances in the generation and control of light, there is much more to be discovered about their quantum counterparts. Here we provide a quantum theory which describes the non-Hermitian physics of chains of coupled modes, which has applications across optics and photonics. We elucidate the origin of the exceptional points which govern the parity-time symmetry, survey their signatures in quantum transport, study their influence for correlations, and account for long-range interactions. We also find how the locations of the exceptional points evolve as a function of the chain length and chain parity, capturing how an arbitrary oligomer chain transitions from its unbroken to broken symmetric phase. Our general results provide perspectives for the experimental detection of parity-time symmetric phases in one-dimensional arrays of quantum objects, with consequences for light transport and its degree of coherence.

title: The Geology of a Part of the Bear River Range and Some Relationships that it Bears with the Rest of the Range
Creators: name: Peterson, Vic E.
Publisher: name: Utah State University
Year: 1936

description: The structure of the western three or four miles of the Bear River range east of Logan, Utah, has many times been alluded to in papers written locally on Cache Valley and the related ranges. There has not however, ever been, to the author's knowledge, an investigation made of this portion of the range for the express purpose of determining its exact structure. Although the area specifically covered by this present investigation is greatly inadequate to base the whole west range structure on, the author believes that the facts brought to light by the specific study of this area, added to the facts already known of the rest of the range, will give a clearer and more comprehensive interpretation of the whole western Bear River range front. It was with this purpose in mind that the present investigation was made. The original outline for the study included an investigation of the paleontology of the section. It was found however, after a few weeks study in the field, that the fossils in the local section are far too scarce for any comprehensive study in the present investigation. The study herein described then will be found to refer to paleontology only where it is necessary or where fossil horizons were found advantageous over lithologic units for mapping of formations. The section represented here has several times been studied in part. With a study of these investigations, it was found that there was enough lithologic difference in most of the sections to make possible local correlation and mapping on that basis. In order to make the present paper more thorough and complete it seemed advisable to branch out from the specific area in a few cases and investigate other parts of the valley and range for further insight.into some of the problems confronted on the area. It was also found necessary to make a rather complete study of the literature of related areas.

description: We study a Bose-Einstein condensate of 52Cr atoms confined in a toroidal trap with a variable strength of s-wave contact interactions. We analyze the effects of the anisotropic nature of the dipolar interaction by considering the magnetization axis to be perpendicular to the trap symmetry axis. In the absence of a central repulsive barrier, when the trap is purely harmonic, the effect of reducing the scattering length is a tuning of the geometry of the system: from a pancake-shaped condensate when it is large, to a cigar-shaped condensate for small scattering lengths. For a condensate in a toroidal trap, the interaction in combination with the central repulsive Gaussian barrier produces an azimuthal dependence of the particle density for a fixed radial distance. We find that along the magnetization direction the density decreases as the scattering length is reduced but presents two symmetric density peaks in the perpendicular axis. For even lower values of the scattering length we observe that the system undergoes a dipolar-induced symmetry breaking phenomenon. The whole density becomes concentrated in one of the peaks, resembling an origin-displaced cigar-shaped condensate. In this context we also analyze stationary vortex states and their associated velocity field, finding that this latter also shows a strong azimuthal dependence for small scattering lengths. The expectation value of the angular momentum along the z direction provides a qualitative measure of the difference between the velocity in the different density peaks.

description: In this technical design report (TDR) executive summary we describe the SABRE South detector to be built at the Stawell Underground Physics Laboratory (SUPL). The SABRE South detector is designed to test the long-standing DAMA/LIBRA signal of an annually modulating rate consistent with dark matter by using the same target material. Located in the Southern Hemisphere, the detector is uniquely positioned to disentangle modulating seasonal effects. SABRE South uses seven ultra-high purity NaI(Tl) crystals (with a total target mass of either 35 kg or 50 kg), hermetically sealed in copper enclosures that are suspended within a liquid scintillator active veto. High quantum efficiency and low background Hamamatsu R11065 photomultiplier tubes are directly coupled to both ends of the crystal, and enclosed with the crystal in an oxygen free copper enclosure. The active veto system consists of 11.6 kL of linear alkylbenzene (LAB) doped with a mixture of fluorophores and contained in a steel vessel, which is instrumented with at least 18 Hamamatsu R5912 photomultipliers. The active veto tags key radiogenic backgrounds intrinsic to the crystals, such as ${^{40}}$K, and is expected to suppress the total background by 27% in the 1-6 keV region of interest. In addition to the liquid scintillator veto, a muon veto is positioned above the detector shielding. This muon veto consists of eight EJ-200 scintillator modules, with Hamamatsu R13089 photomultipliers coupled to both ends. With an expected total background of 0.72 cpd/kg/keV, SABRE South can test the DAMA/LIBRA signal with 5$σ$ discovery or 3$σ$ exclusion after two years of data taking.

Negative effective mass transition and anomalous transport in power-law hopping bands

subject: FOS: Physical sciences

description: We study the stability of spinless Fermions with power law hopping $H_{ij} \propto |i - j|^{-α}$. It is shown that at precisely $α_c =2$, the dispersive inflection point coalesces with the band minimum and the charge carriers exhibit a transition into negative effective mass regime, $m_α^* < 0$ characterized by retarded transport in the presence of an electric field. Moreover, bands with $α< 2$ must be accompanied by counter-carriers with $m_α^* > 0$, having a positive band curvature, thus stabilizing the system in order to maintain equilibrium conditions and a proper electrical response. We further examine the semi-classical transport and response properties, finding an infrared divergent conductivity for 1/r hopping($α=1$). The analysis is generalized to regular lattices in dimensions $d$ = 1, 2, and 3.

title: Geology of the Southern Part of Wellsville Mountain, Wasatch Range, Utah
Creators: name: Gelnett, Ronald H.
Publisher: name: Utah State University
Year: 1958

description: Wellsville Mountain is 10 miles west of Logan, Utah, at the northern extremity of the Wasatch Range. Paleozoic rocks forma northeast-dipping homocline bounded in part by northwest-trending high-angle faults and cut by a series of northeast-trending high-angle faults. A major transverse fault, with a stratigraphic displacement of 4,500 feet, divides the mountain into two distinct blocks.
The rock units of the area are comparable to those of the Logan quadrangle immediately to the east. Pre-Cambrian rocks crop out in Box Elder Canyon, just east of Brigham City, and are overlain by at least 20,000 feet of northeast-dipping Paleozoic rocks of every period except possibly the Permian. The Beirdneau sandstone member of the Jefferson formation, is tentatively correlated with that of the upper Devils Gate limestone of central Nevada. About 6,600 feet of the Oquirrh formation of Pennsylvanian age is exposed near the northern end of Wellsville Mountain. The presence of Desmoinesian fusulinids at the base of the Oquirrh and upper Virgilian fusulinids throughout the interval from 1,000 to 2,000 feet above its base indicates an absence of Lower Pennsylvanian rocks and suggests that the upper 4,400 feet may be in part Permian. Mesozoic rocks are not found in the area. The Wasatch formation and Salt Lake group of Tertiary age crop out in the foothills at the northern end of Wellsville Mountain.
Two fault systems are recognized in the area. The northeast-trending high-angle transverse faults of Laramide age and the north-west-trending high-angle bordering faults are Basin and Range age.
Accurate determination of the Josephson critical current by lock-in measurements

description: Operation of Josephson electronics usually requires determination of the Josephson critical current $I_c$, which is affected both by fluctuations and measurement noise. Lock-in measurements allow obviation of $1/f$ noise and, therefore, provide a major advantage in terms of noise and accuracy with respect to conventional dc-measurements. In this work we show both theoretically and experimentally that the $I_c$ can be accurately extracted using first and third harmonic lock-in measurements of junction resistance. We derive analytic expressions and verify them experimentally on nano-scale Nb-PtNi-Nb and Nb-CuNi-Nb Josephson junctions.

The spin dependence of the Blandford-Znajek effect
Creators: name: Garofalo, David

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The interaction of large scale magnetic fields with the event horizon of rotating black holes (the Blandford-Znajek [1977] mechanism) forms the basis for some models of the most relativistic jets. We explore a scenario in which the central inward "plunging" region of the accretion flow enhances the trapping of large scale poloidal field on the black hole. The study is carried out using a fully relativistic treatment in Kerr spacetime, with the focus being to determine the spin dependence of the Blandford-Znajek effect. We find that large scale magnetic fields are enhanced on the black hole compared to the inner accretion flow and that the ease with which this occurs for lower prograde black hole spin, produces a spin dependence in the Blandford-Znajek effect that has attractive applications to recent observations. Among these is the correlation between inferred accretion rate and nuclear jet power observed by Allen et al. (2006) in X-ray luminous elliptical galaxies. If the black hole rotation in these elliptical galaxies is in the prograde sense compared with that of the inner accretion disk, we show that both the absolute value and the uniformity of the implied jet-production efficiency can be explained by the flux-trapping model. The basic scenario that emerges from this study is that a range of intermediate values of black hole spins could be powering these AGN. We also suggest that the jets in the most energetic radio-galaxies may be powered by accretion onto {\it retrograde} rapidly-rotating black holes.

description: Nachdem lange Zeit die Vorstellung des Cyberspace als virtueller Welt dominierte, setzt sich in Sicherheitskreisen ein immer physischeres Verständnis durch: wer die Geräte und die Leitungen kontrolliert, der kontrolliert auch die darin befindlichen Daten. Inzwischen wurde erkannt, dass die Produktion von Computern und digitalen Geräten kritische Engpässe aufweist und dass die Kontrolle kritischer Elemente wie seltener Metalle und Halbleiter (Computerchips, Rechenchips, Mikroprozessoren) als Kernelement digitaler Geräte für geostrategische Zwecke genutzt werden kann. Ohne fortschrittliche Chips wird der weitere Fortschritt der Digitaltechnik verlangsamt oder ist sogar unmöglich. Aus diesem Grund hat ein intensiver Wettbewerb zwischen den USA und China stattgefunden. Die Marktanalyse zeigt, dass die USA und ihre asiatischen Verbündeten (Japan, Südkorea und Taiwan) die meisten Schritte der Chipproduktion dominieren, während China die Materialien kontrolliert, die für die Produktion der umgebenden Computer und digitalen Geräte benötigt werden, die seltenen Erden. Seit 2018 haben die Vereinigten Staaten schrittweise den Export von Halbleitern und zugehöriger Fertigungsausrüstung nach China eingeschränkt. Unter anderem konnten die Vereinigten Staaten den Verkauf der sogenannten EUV-Technologie an China blockieren, was es für China zukünftig sehr schwierig oder sogar unmöglich machen könnte, fortschrittliche Chips (und damit fortschrittliche Computer) herzustellen. Am 07. Oktober 2022 wurden diese Beschränkungen erheblich ausgeweitet, um Chinas Fähigkeit einzuschränken, fortschrittliche Computerchips zu erwerben, Supercomputer zu entwickeln und zu warten und fortschrittliche Halbleiter herzustellen. Dieser Schritt könnte Chinas technologische Entwicklung für Jahre erheblich verlangsamen und China steht nun vor harten strategischen Alternativen und Entscheidungen.

description: Scalar gluons -- or sgluons -- are color octet scalars without electroweak charges. They occur in supersymmetric models of Dirac gauginos as the scalar partners of the gluino and carry Standard-Model type R charge. This allows them to interact with ordinary matter and to be produced at the LHC, singly as well as in pairs. Sgluons dominantly decay into gluons, top pairs, and a top quark plus a light quark. A pair of sgluons decaying into like-sign tops would provide a striking signature at the LHC. In our discussion of this channel we especially focus on the proper treatment of QCD jets.

title: Cambrian Stratigraphy in the Northern Wasatch Region
Creators: name: Maxey, George Burke
Publisher: name: Utah State University
Year: 1941

description: An exhaustive field study of the Cambrian stratigraphy of the northern Wasatch region indicates that in addition to the Blacksmith Fork section there are two complete and better exposed middle and upper sections. Several other good exposures of the lower Middle Cambrian section have been studied in detail. The Spence shale is found to be a member low in the Langston, not the basal member of the Ute. Relative ages of the Spence shale and Ptarmigania faunas have been determined. Other Cambrian faunal zones have been discovered and are discussed. Paleontologic evidence suggests that the Nounan formation is of Upper Cambrian (Cedaria) age. Laboratory and field evidence indicates the probable Lower Cambrian age of the Brigham formation.
title: The Dry Lake Section of the Brazer Foundation
Creators: name: Yolton, James S.
Publisher: name: Utah State University
Year: 1943

description: The Dry Lake section of the Brazer formation, totalling 3100 feet in thickness, is an excellent exposure containing an abundance of fossils many of which are well preserved. The fauna indicates that the formation is to be correlated with the Upper Iowan end Chester series of the type Mississippian system in the Mississippi Valley section. Substantial fossil evidence indicates the following correlation for the Brazer formation members. The C unit represents the western equivalent of the Middle Meramec group, i.e., the Salem and St. Louis limestones. The D member is decidedly Ste. Genevieve in general faunal aspects but, because of the presence of some Chester fauna, it must be considered as a transition between the Meramec and New Design groups. The F member is, in most respects, typically equivalent of the Chester series.
There are also relationships to tho fauna or the Batesville and Moorefield deposits of Arkansas, to the Lower Caney shale of Oklahoma, and to the Paradise formation of Southeastern Arizona.

description: Assuming that soft X-ray sources in symbiotic stars result from strong thermonuclear runaways, and supersoft X-ray sources from weak thermonuclear runaways or steady hydrogen burning symbiotic stars, we investigate the Galactic soft and supersoft X-ray sources in symbiotic stars by means of population synthesis. The Galactic occurrence rates of soft X-ray sources and supersoft X-ray sources are from $\sim$ 2 to 20 $\rm yr^{-1}$, and $\sim$ 2 to 17 $\rm yr^{-1}$, respectively. The numbers of X-ray sources in symbiotic stars range from 2390 to 6120. We simulate the distribution of X-ray sources over orbital periods, masses and mass-accretion rates of white dwarfs. The agreement with observations is reasonable.
