Sex differences in corticotropin-releasing factor receptor signaling and trafficking: Potential role in female vulnerability to stress-related psychopathology

description: Although the higher incidence of stress-related psychiatric disorders in females is well documented, its basis is unknown. Here, we show that the receptor for corticotropin-releasing factor (CRF), the neuropeptide that orchestrates the stress response, signals and is trafficked differently in female rats in a manner that could result in a greater response and decreased adaptation to stressors. Most cellular responses to CRF in the brain are mediated by CRF receptor (CRFr) association with the GTP-binding protein, G s. Receptor immunoprecipitation studies revealed enhanced CRFr-G s coupling in cortical tissue of unstressed female rats. Previous stressor exposure abolished this sex difference by increasing CRFr-Gs coupling selectively in males. These molecular results mirrored the effects of sex and stress on sensitivity of locus ceruleus (LC)-norepinephrine neurons to CRF. Differences in CRFr trafficking were also identified that could compromise stress adaptation in females. Specifically, stress-induced CRFr association with Β-arrestin2, an integral step in receptor internalization, occurred only in male rats. Immunoelectron microscopy confirmed that stress elicited CRFr internalization in LC neurons of male rats exclusively, consistent with reported electrophysiological evidence for stress-induced desensitization to CRF in males. Together, these studies identified two aspects of CRFr function, increased cellular signaling and compromised internalization, which render CRF-receptive neurons of females more sensitive to low levels of CRF and less adaptable to high levels of CRF. CRFr dysfunction in females may underlie their increased vulnerability to develop stress-related pathology, particularly that related to increased activity of the LC-norepinephrine system, such as depression or post-traumatic stress disorder. © 2010 Macmillan Publishers Limited All rights reserved.

description: We study the "q-commutative" power series ring R:= k q[[x 1,···,x n]], defined by the relations x ixj = q ijx jx i, for mulitiplicatively antisymmetric scalars q ij in a field k. Our results provide a detailed account of prime ideal structure for a class of noncommutative, complete, local, noetherian domains having arbitrarily high (but finite) Krull, global, and classical Krull dimension. In particular, we prove that the prime spectrum of R is normally separated and is finitely stratified by commutative noetherian spectra. Combining this normal separation with results of Chan, Wu, Yekutieli, and Zhang, we are able to conclude that R is catenary. Following the approach of Brown and Goodearl, we also show that links between prime ideals are provided by canonical automorphisms. Moreover, for sufficiently generic q ij, we find that R has only finitely many prime ideals and is a UFD (in the sense of Chatters). © Springer Science+Business Media B.V. 2010.
Dispersion interactions and reactive collisions of ultracold polar molecules

description: Progress in ultracold experiments with polar molecules requires a clear understanding of their interactions and reactivity at ultralow collisional energies. Two important theoretical steps in this process are the characterization of interaction potentials between molecules and the modeling of the reactive scattering mechanism. Here, we report on the ab initio calculation of isotropic and anisotropic van der Waals interaction potentials for polar KRb and RbCs colliding with each other or with ultracold atoms. Based on these potentials and two short-range scattering parameters, we then develop a single-channel scattering model with flexible boundary conditions. Our calculations show that, at low temperatures (and in the absence of an external electric field), the reaction rates between molecules or between molecules and atoms have a resonant character as a function of the short-range parameters. We also find that both the isotropic and anisotropic van der Waals coefficients have significant contributions from dipóle coupling to excited electronic states. Their values can differ dramatically from those solely obtained from the permanent dipóle moment. A comparison with recently obtained reaction rates of fermionic 40K87Rb shows that the experimental data cannot be explained by a model where the short-range scattering parameters are independent of the relative orbital angular momentum or partial wave. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.

description: The dynamic interplay of transport, electrostatic, and magnetic effects in the resonant tunneling through ferromagnetic quantum wells is theoretically investigated. It is shown that the carrier-mediated magnetic order in the ferromagnetic region not only induces, but also takes part in intrinsic, robust, and sustainable high-frequency current oscillations over a large window of nominally steady bias voltages. This phenomenon could spawn a new class of quantum electronic devices based on ferromagnetic semiconductors.

description: We present images and light curves of the bipolar Planetary Nebula RPJ 053059-683542 that was discovered in the Reid-Parker AAO/UKST H-alpha survey of the Large Magellanic Cloud (LMC). The emission from this object appears entirely nebular, with the central star apparently obscured by a central band of absorption that bisects the nebula. The light curves, which were derived from images from the SuperMACHO project at CTIO, showed significant, spatially resolved variability over the period 2002 January through 2005 December. Remarkably, the emission from the two bright lobes of the nebula vary either independently, or similarly but with a phase lag of at least one year. The optical spectra show a low level of nebular excitation, and only modest N enrichment. Infrared photometry from the 2MASS and SAGE surveys indicates the presence of a significant quantity of dust. The available data imply that the central star has a close binary companion, and that the system has undergone some kind of outburst event that caused the nebular emission to first brighten and then fade. Further monitoring, high-resolution imaging, and detailed IR polarimetry and spectroscopy would uncover the nature of this nebula and the unseen ionizing source.

Biological control of olive green mold in the cultivation of Agaricus bisporus

description: The Canadian mushroom industry is experiencing the same problems as are encountered worldwide - attacks of diseases and pests (lngratta, 1980). Successful methods to control the damaging weed mold -Chaetomium olivaceum (Olive green mold) in mushroom beds are presently not known. This thesis investigation attempted to control C. olivaceum by biological means. A thermophilic Bacillus sp (resembling B. coagu-lans - resistant to 0.02% sodium azide, acidophilic) which showed dramatic activity against C. olivaceum on TSY (Trypticase soy agar + 0.1% Yeast extract) agar plates was isolated from commercial mushroom compost (phase I). When inoculated into conventional and hydroponic mushroom beds, the Bacillus not only provided a significant degree of protection from C. olivaceum but also increased yields of Agaricus bisporus. This is the first isolation of a microorganism inhibitory to Olive green mold. The Bacillus was shown to produce an extremely potent and stable antibiotic (named Chaetomacin) effective over a wide range of both pH (2-10) and temperature (-15°C to 150°C). Chaetomacin is soluble in most polar solvents and insoluble in non-polar solvents. This antibiotic produced at mesophilic temperatures is also active against other Bacillus species and various eukaryotes - but demonstrates no activity against Cram negative organisms or Gram positive cocci. Final purification of Chaetomacin was accomplished through thin layer chromatography on Silica gel analytical plates. Amino acid analysis revealed the antibiotic to be a peptide, acidic in nature. Examination of the literature reveals no other previously isolated antibiotics which are identical to Chaetomacin.

description: Eucosmocydia oedipus Diakonoff, 1988
Eucosmocydia oedipus Diakonoff 1988: 326, fig. 17, 32; Brown 2005: 335.
Remarks. Eucosmocydia oedipus Diakonoff, 1988 is the type species of Eucosmocydia. Although we have not examined the holotype, its identity is unambiguous from the original description. According to Diakonoff (1988), E. oedipus is a broad-winged species superficially resembling species of the genus Grapholita Treitschke. The “forewing is purplish-fuscous, closely and finely striated with pale cinerous (tip of scales).” Wingspan 10 mm. “Hind tibia glossy dark grey, a thick pencil of hair-scales dark grey-bronze, posterior tarsus glossy golden.” “Hind wing dorsal lobe grey, black-tipped.” The male genitalia (Diakonoff 1988: fig. 17) are typical of several species of Eucosmocydia, differing from those of the species treated in the present contribution by an even higher tegumen. The valva is slender with a long cucullus, similar to that of E. kirimiriana (Fig. 27). Although Razowski and Trematerra (2008) reported E. oedipus from Mozambique, their illustration of the male genitalia does not agree with Diakonoff ’s (1988) figure. The cucullus of the valva in the specimen from Mozambique (Razowski and Trematerra 2008, fig. III, 10) is subrectangular, whereas the shape of the valva in the holotype of E. oedipus is more rounded and apically tapered. Presently, E. oedipus is known only from the holotype from Madagascar. DNAbarcode sequences and the life history are unknown.

Negative ion avalanche

description: Time projection chambers drifting negative ions (NITPC) instead of electrons have several advantages. A NITPC can operate at very high reduced drift fields without diffusion runaway, and the readout digitization sampling rate requirement is considerably relaxed due to the low drift speed of negative ions. The initiation of Townsend avalanches to allow gas gain in these devices has not been understood until now. It is shown here that the avalanche in low pressure CS2 vapor is most likely initiated by collisional detachment of the electron from the negative molecular ion. In mixtures of nitromethane vapor with CO2 the mechanism appears to be more complex. © 2010 Elsevier B.V. All rights reserved.

description: Writing, especially academic writing, is highly valued in foreign language acquisition,particularly for English majors. Nevertheless, using academic terminology might bedifficult for students still developing their academic language abilities. The purpose ofthis research is to understand students' difficulties in selecting appropriate words inacademic writing and offer solutions to overcome such difficulties. The participants were78 English majors (high-quality program, course 45) and three lecturers at theDepartment of English Language and Culture, School of Foreign Languages, Can ThoUniversity. Questionnaires were used to measure their difficulties in word choice inacademic writing and semi-structured interviews were utilized to find solutions. Theresults show that most participants had a basic knowledge of academic vocabulary,which was demonstrated through their ability to select the appropriate word choice.However, students found it difficult to choose the right words in their academic writing.The reasons are that academic words are not easy to remember and not successfully usedin the context of the meaning of the word and do not have an effective method of learningacademic vocabulary. Based on the results, several specific approaches have beenproposed to help students find the most suitable strategies for learning and usingacademic vocabulary for their writing.
Automating network resource allocation for coflows with deadlines

description: Die Coflow-Abstraktion wird zur Spezifikation der Netzressourcenanforderungen von datenparallelen Anwendungen verwendet. Sie repräsentiert korrelierte Flüsse in Datenflussmodellen wie MapReduce oder Partition-Aggregate. In dieser Dissertation zeige ich, dass manuell entworfene Online-Coflow-Scheduler zur Zuweisung von Datenraten an solche Flüsse durch einen auf Reinforcement Learning (RL) basierenden Coflow-Scheduler ersetzt werden können. Dies automatisiert die Zuweisung von Netzressourcen an Coflows über den Entwurf eines Verfahrens hinaus. Konkret lernt ein RL-basierter Coflow-Scheduler Planungsrichtlinien, um ein Leistungsziel von Coflows zu optimieren, z. B. die Maximierung der Coflow-Zulassungen bei gleichzeitiger Einhaltung ihrer Fristen. In dieser Dissertation habe ich drei Hauptbeiträge geleistet: Zunächst stelle ich eine neue Coflow-Heuristik vor, die freigegebene Netzressourcen von Coflows nutzt, die vor Fristablauf einer anderen Coflow-Anforderung enden und diese an andere, ggf. neue Coflows zuweist. Dann zeige ich, dass Flow-oder Coflow-Heuristiken im Allgemeinen dazu neigen, bei der Maximierung der (Co)Flow-Zulassungen schlecht abzuschneiden, wenn im Datenverkehr stochastische Flows oder Coflows ankommen. Als Nächstes zeige ich, dass ein Online-Flow-Scheduler mit Hilfe von Reinforcement Learning eine Scheduling-Politik zur Maximierung der Flow-Zulassungen erlernen kann. Schließlich zeige ich, wie ein Coflow-Scheduler bei stochastischen Coflow-Ankünften Strategien erlernen kann, um die Coflow-Zulassungen zu maximieren und gleichzeitig ihre Fristen einhalten.
description: The coflow abstraction is used for specifying network resource requirements of data-parallel applications. It represents correlated flows in data flow models like MapReduce and partition-aggregate. In this dissertation, I mainly demonstrate that hand-crafted online coflow schedulers --- to allocate data rates to correlated flows --- can be replaced with a reinforcement learning (RL) based coflow scheduler to automate network resource allocation of coflows for data-parallel applications. Specifically, an RL-based coflow scheduler learns scheduling policies to optimize for a high-level performance objective of coflows, for example, maximize coflow admissions while meeting their deadlines. In this dissertation, I have made three main contributions: I first present a new coflow heuristic that leverages released network resources of active coflows finishing before the deadline of a new coflow request. I then show that flow or coflow heuristics, in general, are prone to under-perform in maximizing (co)flow admissions because of stochastic flow or coflow arrivals in data traffic. Next, I demonstrate that an online flow scheduler can learn a scheduling policy to maximize flow admissions using reinforcement learning. Finally, I show how a coflow scheduler can learn policies in the presence of stochastic coflow arrivals to maximize coflow admissions while meeting their deadlines.

description: This paper gives the first explicit, two-sided estimates on the cusp area of once-punctured-torus bundles, 4-punctured sphere bundles, and two-bridge link complements. The input for these estimates is purely combinatorial data coming from the Farey tessellation of the hyperbolic plane. The bounds on cusp area lead to explicit bounds on the volume of Dehn fillings of these manifolds, for example, sharp bounds on volumes of hyperbolic closed 3-braids in terms of the Schreier normal form of the associated braid word. Finally, these results are applied to derive relations between the Jones polynomial and the volume of hyperbolic knots, and to disprove a related conjecture. The Author 2010.

description: We present a study of high energy photodisintegration of proton-pairs through the γ + 3He → p + p + n channel. Photon energies, Eγ, from 0.8 to 4.7 GeV were used in kinematics corresponding to a proton pair with high relative momentum and a neutron nearly at rest. The s-11 scaling of the cross section, as predicted by the constituent counting rule for two nucleon photodisintegration, was observed for the first time. The onset of the scaling is at a higher energy and the cross section is significantly lower than for deuteron (pn pair) photodisintegration. For Eγ below the scaling region, the scaled cross section was found to present a strong energy-dependent structure not observed in deuteron photodisintegration. © 2010 Elsevier B.V.

Localities and specimens found: 50 – 3♀, 1♀ ov, 1j; 51 – 11♀, 1♀ ov, 2♀ em, 2j.
Distribution and ecology. Alonella excisa s. lat. is one of the most known members of the genus distributed almost worldwide (Smirnov 1996; Kotov et al. 2013a; Korovchinsky et al. 2021b).This taxon is evidently represented by a complex of related species that require further investigation, including in the Asian region (Smirnov 1996; Kotov et al. 2013b; Neretina et al. 2021). In the Oriental area, A. excisa -like individuals are noted relatively often (Chiang & Du 1979; Idris & Fernando 1981; Idris 1983; Michael & Sharma 1988; Maiphae et al. 2005, 2008; Tanaka & Ohtaka 2010; Chatterjee et al. 2013; Korovchinsky 2013; Kotov et al. 2013b; Van Damme et al. 2013; Ji et al. 2015; Sinev et al. 2015, 2020; Lopez et al. 2017; Sharma & Sharma 2017; Gogoi et al. 2018; Tiang-nga et al. 2020; Dadykin et al. 2023). In Vietnam, these crustaceans were mainly designated as A. excisa excisa (Fischer, 1854) (Dang et al. 1980, 2002; Dang & Ho 2001; Duong et al. 2008; Sinev & Semenyuk 2021).
Alonella excisa s. lat. is an eurybiontic chydorid found in plankton, benthos and among aquatic vegetation of various types of water bodies, in big ones mainly in the littoral zone (Idris 1983; Duong et al. 2008; Lopez et al. 2017; Korovchinsky et al. 2021b). In our material, these crustaceans were encountered only in samples from the root system of floating macrophytes (see Appendix 1).

Interpolations of the NNLO epsilon expansions around four and two spatial dimensions with the use of Pade approximants give xi=0.360+/-0.020 in three dimensions with the uncertainty due to different interpolation functions. This value is consistent with the previous interpolations of the NLO epsilon expansions xi=0.377+/-0.014 in spite of the large NNLO corrections.

description: The STAR experiment at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory is carrying out a spin physics program in high-energy polarized + collisions at 200 - 500 GeV to gain a deeper insight into the spin structure and dynamics of the proton. One of the main objectives of the spin physics program at RHIC is the extraction of the polarized gluon distribution function based on measurements of gluon initiated processes, such as hadron and jet production. The STAR detector is well suited for the reconstruction of various final states involving jets, π0, π, e and γ, which allows to measure several different processes. Recent results will be shown on the measurement of jet production and hadron production at 200 GeV. The RHIC spin physics program has recently completed the first data taking period in 2009 of polarized + collisions at 500 GeV.

Renormalization Regularization and Renormalons

description: We present results for the renormalization constants of bilinear quark operators obtained by using the tree-level Symanzik improved gauge action and the N f = 2 twisted mass fermion action at maximal twist, which guarantees automatic O(a)-improvement. Our results are also relevant for the corresponding standard (un-twisted) Wilson fermionic action since the two actions only differ, in the massless limit, by a chiral rotation of the quark fields. The scale-independent renormalization constants Z V, Z A and the ratio Z P /Z S have been computed using the RI-MOMapproach, as well as other alternative methods. For Z A and Z P /Z S, the latter are based on both standard twisted mass and Osterwalder-Seiler fermions, while for Z V a Ward Identity has been used. The quark field renormalization constant Z q and the scale dependent renormalization constants Z S, Z P and Z T are determined in the RI-MOM scheme. Leading discretization effects of O(g2a2), evaluated in one-loop perturbation theory, are explicitly subtracted from the RI-MOM estimates. © 2010 SISSA, Trieste, Italy.

On diagrammatic bounds of knot volumes and spectral invariants

Subjects: Knot volume
Twist number
Generalized twist number
Expanding family

description: In recent years, several families of hyperbolic knots have been shown to have both volume and λ1 (first eigenvalue of the Laplacian) bounded in terms of the twist number of a diagram, while other families of knots have volume bounded by a generalized twist number. We show that for general knots, neither the twist number nor the generalized twist number of a diagram can provide two-sided bounds on either the volume or λ1. We do so by studying the geometry of a family of hyperbolic knots that we call double coil knots, and finding two-sided bounds in terms of the knot diagrams on both the volume and on λ1. We also extend a result of Lackenby to show that a collection of double coil knot complements forms an expanding family iff their volume is bounded. © 2009 Springer Science+Business Media B.V.
First principles prediction of the Al-Li phase diagram

description: The phase diagram of the Al-Li system was determined by means of first principles calculations in combination with the cluster expansion formalism and statistical mechanics. The ground state phases were determined from first principles calculations of fcc and bcc configurations in the whole compositional range while the phase transitions as a function of temperature were ascertained from the thermodynamic grand potential and the Gibbs free energies of the phases. Overall, the calculated phase diagram was in good agreement with the currently accepted experimental phase diagram but the simulations provided new insights that are important to optimize microstructure of these alloys by means of heat treatments. In particular, the structure of the potential GP zones, made up of Al0.5Li0.5 (001) monolayers embedded in Al matrix, was identified. It was found that Al3Li is a stable phase although the energy barrier for the transformation of Al3Li into AlLi is very small (a few meV) and can be overcome by thermal vibrations. Moreover, bcc AlLi was found to be formed by martensitic transformation of fcc configurations and Al3Li precipitates stand for favorable sites for the nucleation of AlLi because they contain the basic blocks of such fcc ordering. Finally, polynomial expressions of the Gibbs free energies of the different phases as a function of temperature and composition were given, so they can be used in mesoscale simulations of precipitation in Al-Li alloys.

The energy linearity and resolution, as well as the spatial resolution of the prototype to electromagnetic and hadronic showers are studied with E=20-200 GeV electrons, E=20-350 GeV pions, and E=50,150 GeV muons from beam tests carried out at CERN/SPS in 2004. The responses of the calorimeter using two different types of photodetectors (avalanche photodiodes APDs, and photomultiplier tubes PMTs) are compared.

description: Eucosmocydia hymenosa (Razowski, 2013), new combination
Fig. 17, 46
Grapholita hymenosa Razowski 2013: 171.
Diagnosis. In facies, E. hymenosa is similar to E. lecaniodiscana with the forewing rather cream and pale brown in the basal half and darker brown in distal half (Fig. 17). Because E. hymenosa is known only from the female, male secondary features, which are usually diagnostic for members of this group, are unknown. Nonetheless, E. hymenosa can be distinguished by the presence of a pair of weak patches posterad of the sterigma, and a much narrower and shallower pocket of the sterigma.
Redescription. Male. Unknown. Female. Head. Vertex and frons pale orange-yellow, sprinkled with brownish gray [now lacking, details from Razowski 2013]. Thorax. Nota pale orange yellow, sprinkled with brownish grey. Forewing (Fig. 17) length 7.0 mm (n = 1); forewing broad, expanding to middle; costa convex; termen weakly concave beneath apex, broadly convex otherwise; upperside ground color orange yellow, sprinkled and strigulated greyish brown; some longitudinal strigulae at middle of wing; costal strigulae cream, slender, subapical strigula broad, paler, divisions brownish; dorsal patch slightly paler than remainder of wing, with brownish lines; tornal area brown; small blotch at mid-termen; speculum orange-yellow with three brown strigulae. Fringe brownish, orange-yellow at apex. Hindwing uniformly brown. Fringe white-cream with brown basal line. Abdomen. Genitalia (Fig. 46) with papillae anales and apophyses as described for genus; sterigma membranous with a pair of weakly spined patches in posterior part, comprised of thick membrane, antrum of similar composition; ductus bursae long, slender; corpus bursae ovoid with a pair of thorn-shaped signa.
DNA barcodes. There are no sequence data available for this species.
Type. Holotype ♀, Nigeria, [Oyo State], Ibadan, [International Institute of Tropical Agriculture], Golf Course Lake, 6–10 Feb 1978, D. & M. Davis, USNM slide 143,024 (USNM).
Distribution and biology. The life history is unknown, but based on related species, it is likely that the larvae of E. hymenosa feed in the fruit of Sapindaceae.

description: In recent years, we constructed a microscopic optical potential (OP) for elastic nucleon-nucleus ($NA$) scattering using modern approaches based on chiral theories for the nucleon-nucleon ($NN$) interaction. The OP was derived at first order of the spectator expansion in Watson multiple scattering theory and its final expression was a folding integral between the $NN$ $t$ matrix and the nuclear density of the target. Two- and three-body forces are consistently included both in the target and in the projectile description. The purpose of this work is to apply our microscopic OP to nuclei characterized by a ground state of spin-parity quantum numbers $J^π\ne 0^+$. We extended our formalism to include the spin of the target nucleus. The full amplitudes of the $NN$ reaction matrix are retained in the calculations starting from two- and three-body chiral forces. We show a remarkable agreement with experimental data for the available observables and, simultaneously, provide reliable estimates for the theoretical uncertainties. This work paves the way toward a full microscopic approach to inelastic $NA$ scattering, showing that the derivation of optical potentials between states with $J^π\ne 0^+$ is completely under control.

Pricing Perishables with Uncertain Demand, Substitutes, and Consumer Heterogeneity
Creators: name: Weaver, Robert D.

Publisher: name: International Journal on Food System Dynamics
Year: 2019
Subjects: Dynamic pricing; perishables; uncertainty; demand substitution; robust optimization; waste management

description: Within the marketing window for perishables such as food products, demand uncertainty is complicated by price sensitivity and propensity to postpone purchase that is heterogeneous across consumers. These features pose substantial challenges to retailers when pricing multiple products over time and across consumer segments. Getting the dynamic profile of prices right has implications for performance of vertical food chains ranging from revenues to food waste. This paper proposes an approach to dynamic pricing that is demonstrated to improve performance within this setting.

description: Millions of people regularly obtain insufficient sleep 1. Given the effect of sleep deprivation on our lives, understanding the cellular and molecular pathways affected by sleep deprivation is clearly of social and clinical importance. One of the major effects of sleep deprivation on the brain is to produce memory deficits in learning models that are dependent on the hippocampus 2-5. Here we have identified a molecular mechanism by which brief sleep deprivation alters hippocampal function. Sleep deprivation selectively impaired 3′, 5′-cyclic AMP (cAMP)- and protein kinase A (PKA)dependent forms of synaptic plasticity 6 in the mouse hippocampus, reduced cAMP signalling, and increased activity and protein levels of phosphodiesterase 4 (PDE4), an enzyme that degrades cAMP. Treatment of mice with phosphodiesterase inhibitors rescued, the sleep-deprivation-induced deficits in cAMP signalling, synaptic plasticity and hippocampus-dependent memory. These findings demonstrate that brief sleep deprivation disrupts hippocampal function by interfering with cAMP signalling through increased PDE4 activity. Thus, drugs that enhance cAMP signalling may provide a new therapeutic approach to counteract the cognitive effects of sleep deprivation ©2009 Macmillan Publishers Limited. All rights reserved.
