Throughout much of her early journalism, Djuna Barnes reconstructs the roles that women hold in the modern city. I discuss Barnes's articles that focus on leisure and entertainment, where she reworks ...the conversation surrounding women's presence and mobility in public and normalizes the female urban experience. Barnes is subversive in her ability to locate women in new and emerging places of public mass entertainment and modern city life and her stories are grounded in the physically built environment, exposing the everyday scenes of the city to her readers. Barnes borrows techniques from flânerie throughout her journalism to document the changing urban geographies that resulted in women's new agencies and mobilities within the modernist city. Women's experience of the city is crucial to understanding how transformations associated with modernity occurred and reverberated across society and Barnes's portrayal of women's leisure and entertainment at the turn-of-the-century provides a rich account of the gendered aspects of modernity in urban settings.
While skeletal muscle creatine levels can be enhanced by exogenous creatine supplementation, the elevation of brain creatine levels with oral creatine administration remains a challenge due to a lack ...of effective transportation of creatine through the blood-brain barrier. Intranasal administration can bypass the blood-brain barrier and deliver drugs directly to the brain. The purpose of this study was to assess the effect of intranasal administration of creatine on brain creatine level and cognitive performance. Rats were randomly assigned into three groups intranasal administration group, oral administration group, and control group. The intranasal group exhibited fewer errors and shorter primary latency compared to the control and oral groups, respectively, during the acquisition phase of the Barnes maze. The intranasal group spent a higher percentage of time in the target quadrant during the probe trial compared to the control group. Biochemical measurements showed that the concentration of creatine in the olfactory bulbs, medial prefrontal cortex, and hippocampus of the rats in the intranasal group was higher than in the oral, and control groups. These results indicate that intranasal administration of creatine hydrochloride increases the creatine level in the rat’s brain’s and improves their performance in the Barnes maze.
•Rats were administered creatine intranasally or orally and compared.•Intranasal creatine administration increased creatine levels in the brain.•Rats with intranasal creatine performed better in Barnes maze test.

In 1921 Mellin published a Comptes Rendu paper computing the principal solution of a polynomial using generalized hypergeometric functions of its coefficients. He used an integral transform nowadays ...bearing his name. Slightly over three pages, the paper is written in French in a terse style befitting the language. This article makes Mellin’s landmark result accessible to people who are not experts in hypergeometric functions and complex analysis by deriving detailed proofs that were omitted in Mellin’s paper.

A new 11 year (2004–2014) monthly 1° gridded Argo temperature and salinity data set with 49 vertical levels from the surface to 1950 m depth (named BOA‐Argo) is generated for use in ocean research ...and modeling studies. The data set is produced based on refined Barnes successive corrections by adopting flexible response functions based on a series of error analyses to minimize errors induced by nonuniform spatial distribution of Argo observations. These response functions allow BOA‐Argo to capture a greater portion of mesoscale and large‐scale signals while compressing small‐sale and high‐frequency noise relative to the most recent version of the World Ocean Atlas (WOA). BOA‐Argo data set is evaluated against other gridded data sets, such as WOA13, Roemmich‐Argo, Jamestec‐Argo, EN4‐Argo, and IPRC‐Argo in terms of climatology, independent observations, mixed‐layer depth, and so on. Generally, BOA‐Argo compares well with other Argo gridded data sets. The RMSEs and correlation coefficients of compared variables from BOA‐Argo agree most with those from the Roemmich‐Argo. In particular, more mesoscale features are retained in BOA‐Argo than others as compared to satellite sea surface heights. These results indicate that the BOA‐Argo data set is a useful and promising adding to the current Argo data sets. The proposed refined Barnes method is computationally simple and efficient, so that the BOA‐Argo data set can be easily updated to keep pace with tremendous daily increases in the volume of Argo temperature and salinity data.
Key Points
A new gridded Argo data set, BOA‐Argo, is produced using refined Barnes successive corrections
The new data set is comparable or slightly better than other gridded Argo data sets produced using OI or variational analysis
The BOA‐Argo is able to retain more mesoscale features than other gridded Argo data sets
The Barnes maze is a task used to assess spatial learning and memory in rodents. It requires animals to learn the position of a hole that can be used as an escape from a bright and open arena. The ...often-used parameters of latency and path length to measure learning and memory do not reflect the different navigation strategies chosen by the animals. Here, we propose an 11-point scoring scheme to classify the search strategies developed by the animals during the initial training as well as after the change of the escape target to a new position. Strategy scores add an important dimension to time and path length to assess the behavior in this popular maze.
Let X and Y be K-equivalent toric Deligne–Mumford stacks related by a single toric wall-crossing. We prove the Crepant Transformation Conjecture in this case, fully-equivariantly and in genus zero. ...That is, we show that the equivariant quantum connections for X and Y become gauge-equivalent after analytic continuation in quantum parameters. Furthermore we identify the gauge transformation involved, which can be thought of as a linear symplectomorphism between the Givental spaces for X and Y, with a Fourier–Mukai transformation between the K-groups of X and Y, via an equivariant version of the Gamma-integral structure on quantum cohomology. We prove similar results for toric complete intersections. We impose only very weak geometric hypotheses on X and Y: they can be non-compact, for example, and need not be weak Fano or have Gorenstein coarse moduli space. Our main tools are the Mirror Theorems for toric Deligne–Mumford stacks and toric complete intersections, and the Mellin–Barnes method for analytic continuation of hypergeometric functions.
