description: We recently introduced a new representation for loop quantum gravity, which is based on the BF vacuum and is in this sense much nearer to the spirit of spin foam dynamics. In the present paper we lay out the classical framework underlying this new formulation. The central objects in our construction are the so-called integrated fluxes, which are defined as the integral of the electric field variable over surfaces of codimension one, and related in turn to Wilson surface operators. These integrated flux observables will play an important role in the coarse graining of states in loop quantum gravity, and can be used to encode in this context the notion of curvature-induced torsion. We furthermore define a continuum phase space as the modified projective limit of a family of discrete phase spaces based on triangulations. This continuum phase space yields a continuum (holonomy-flux) algebra of observables. We show that the corresponding Poisson algebra is closed by computing the Poisson brackets between the integrated fluxes, which have the novel property of being allowed to intersect each other.

description: Extracellular signal-regulated kinase (ERK1/2) has been implicated in modulating drug seeking behavior and is a target of alcohol and other drugs of abuse. Given that the discriminative stimulus (subjective/interoceptive) effects of drugs are determinants of abuse liability and can influence drug seeking behavior, we examined the role of ERK1/2 in modulating the discriminative stimulus effects of alcohol. Using drug discrimination procedures, rats were trained to discriminate a moderate intragastric (IG) alcohol dose (1 g/kg) versus water (IG). Following an alcohol (1 g/kg) discrimination session phosphorylated ERK1/2 (pERK1/2) immunoreactivity (IR) was significantly elevated in the amygdala, but not the nucleus accumbens. Therefore, we hypothesized that intra-amygdala inhibition of ERK1/2 would disrupt expression of the discriminative stimulus effects of alcohol. However, intra-amygdala or accumbens administration of the MEK/ERK1/2 inhibitor U0126 (1 and 3 μg) had no effect on the discriminative stimulus effects of the training dose of alcohol (1 g/kg). Contrary to our hypothesis, intra-amygdala infusion of U0126 (3 μg) potentiated the discriminative stimulus effects of a low alcohol dose (0.5 g/kg) and had no effect following nucleus accumbens infusion. Importantly, site-specific inhibition of pERK1/2 in each brain region was confirmed. Therefore, the increase in pERK1/2 IR in the amygdala following systemic alcohol administration may be reflective of the widespread effects of alcohol on the brain (activation/inhibition of brain circuits), whereas the site specific microinjection studies confirmed functional involvement of intra-amygdala ERK1/2. These findings show that activity of the ERK signaling pathway in the amygdala can influence the discriminative stimulus effects of alcohol.

description: This project explores different aspects of inclusive excellence discourse and practices in academic libraries. Designed as a case study and content analysis, this project examines academic libraries at four R1 institutions located in the eastern United States. Three main characteristics are explored: one looks at what these conversations or initiatives look like and how they manifest in these spaces; the second investigates the sustainability of these practices. The third evaluates how inclusive practices impact job satisfaction and staff well- being. Semi-structured interviews were conducted utilizing convenience sampling, along with a content analysis of existing publicly available information. Results gathered from this study corroborate what the literature suggests and demonstrate that extensive work needs to be done to transform librarianship, but existing conversations and initiatives happening indicate that progress is being made. The information produced in this case study encourages further exploration of the current work being done to embody a transformed and more inclusive profession.

description: The recreational use of cathinone-derived synthetic stimulants, also known as "bath salts", has increased during the last five years. A commonly abused drug in this class is mephedrone (4-methylmethcathinone or "meow-meow"), which alters mood and produces euphoria in humans. Intracranial self-stimulation (ICSS) measures the behavioral effects of neuroactive compounds on brain reward circuitry. We used ICSS to investigate the ability of mephedrone and cocaine to alter responding for electrical stimulation of the medial forebrain bundle in C57BL/6J mice. Adult male C57BL/6J mice (n=6) implanted with unipolar stimulating electrodes at the level of the lateral hypothalamus responded for varying frequencies of brain stimulation reward (BSR). The frequency that supported half maximal responding (EF50), the BSR threshold (θ(0)), and the maximum response rate were determined before and after intraperitoneal administration of saline, mephedrone (1.0, 3.0, or 10.0 mg/kg), or cocaine (1.0, 3.0, or 10.0 mg/kg). Mephedrone dose-dependently decreased EF50 (max. effect=72.3% of baseline), θ(0) (max. effect=59.6% of baseline), and the maximum response rate (max. effect=67.0% of baseline) beginning 15 min after administration. Beginning immediately after administration, cocaine dose-dependently lowered EF50 (max. effect=66.4% of baseline) and θ(0) (max. effect=60.1% of baseline) but did not affect maximum response rate. These results suggest that mephedrone, like cocaine, potentiates BSR, which may indicate its potential for abuse. Given the public health concern of stimulant abuse, future studies will be necessary to determine the cellular and behavioral effects of acute and chronic mephedrone use.

description: Rapid development in numerical modelling of materials and the complexity of new models increases quickly together with their computational demands. Despite the growing performance of modern computers and clusters, calibration of such models from noisy experimental data remains a nontrivial and often computationally exhaustive task. The layered neural networks thus represent a robust and efficient technique to overcome the time-consuming simulations of a calibrated model. The potential of neural networks consists in simple implementation and high versatility in approximating nonlinear relationships. Therefore, there were several approaches proposed to accelerate the calibration of nonlinear models by neural networks. This contribution reviews and compares three possible strategies based on approximating (i) model response, (ii) inverse relationship between the model response and its parameters and (iii) error function quantifying how well the model fits the data. The advantages and drawbacks of particular strategies are demonstrated on the calibration of four parameters of the affinity hydration model from simulated data as well as from experimental measurements. This model is highly nonlinear, but computationally cheap thus allowing its calibration without any approximation and better quantification of results obtained by the examined calibration strategies. The paper can be thus viewed as a guide intended for the engineers to help them select an appropriate strategy in their particular calibration problems.

description: The Melanocortin (MC) system is one of the crucial neuropeptidergic systems that modulate energy balance. The roles of endogenous MC and MC-4 receptor (MC4-R) signaling within the hypothalamus in the control of homeostatic aspects of feeding are well established. Additional evidence points to a key role for the central MC system in ethanol consumption. Recently, we have shown that nucleus accumbens (NAc), but not lateral hypothalamic (LH), infusion of a selective MC4-R agonist decreases ethanol consumption. Given that MC signaling might contribute to non-homeostatic aspects of feeding within limbic circuits, we assessed here whether MC4-R signaling within the NAc and the lateral hypothalamus (LH) alters normal ingestive hedonic and/or aversive responses to ethanol in rats as measured by a taste reactivity test. Adult male Sprague-Dawley rats were given NAc- or LH- bilateral infusion of the selective MC4-R agonist cyclo (NH-CH2-CH2-CO-His-D-Phe-Arg-Trp-Glu)-NH2 (0, 0.75 or 1.5 µg/0.5µl/site) and following 30 min, the animals received 1 ml of ethanol solution (6% w/v) intraoral for 1 minute and aversive and hedonic behaviors were recorded. We found that NAc-, but not LH-administration, of a selective MC4-R agonist decreased total duration of hedonic reactions and significantly increased aversive reactions relative to saline-infused animals which support the hypothesis that MC signaling within the NAc may contribute to ethanol consumption by modulating non-homeostatic aspects (palatability) of intake.

These bases contain dual canonical bases of upper and lower halves of $U_q(\mathfrak g)$ and are invariant under many symmetries including all Lusztig's symmetries if $\mathfrak g$ is semisimple. It also turns out that a part of a double canonical basis of $U_q(\mathfrak g)$ spans its center.

description: Optogenetic techniques have given researchers unprecedented access to the function of discrete neural circuit elements and have been instrumental in the identification of novel brain pathways that become dysregulated in neuropsychiatric diseases. For example, stress is integrally linked to the manifestation and pathophysiology of neuropsychiatric illness, including anxiety, addiction and depression. Due to the heterogeneous populations of genetically and neurochemically distinct neurons in areas such as the bed nucleus of the stria terminalis (BNST), as well as their substantial number of projections, our understanding of how neural circuits become disturbed after stress has been limited. Using optogenetic tools, we are now able to selectively isolate distinct neural circuits that contribute to these disorders and perturb these circuits in vivo, which in turn may lead to the normalization of maladaptive behavior. This review will focus on current optogenetic strategies to identify, manipulate, and record from discrete neural circuit elements in vivo as well as highlight recent optogenetic studies that have been utilized to parcel out BNST function.

description: We improve upon a recently introduced efficient quantum state reconstruction procedure targeted to states well-approximated by the multi-scale entanglement renormalization ansatz (MERA), e.g., ground states of critical models. We show how to numerically select a subset of experimentally accessible measurements which maximizes information extraction about renormalized particles, thus dramatically reducing the required number of physical measurements. We numerically estimate the number of measurements required to characterize the ground state of the critical 1D Ising (resp. XX) model and find that MERA tomography on 16-qubit (resp. 24-qubit) systems requires the same experimental effort than brute-force tomography on 8 qubits. We derive a bound computable from experimental data which certifies the distance between the experimental and reconstructed states.

description: From 1904-1960, over 3,500 Alaskans were deemed insane by a jury and sent to the privately-owned Morningside Hospital in Portland, Oregon. The Morningside Hospital History Project (MHHP) aims to find these “Lost Alaskans” by digitizing archival documentation scattered across the country, reconnecting families with information about their lost relatives, and bringing the history of Morningside back into public memory. As a volunteer-run organization with no ties to a larger institution and a unique modus operandi of guerilla virtual reunification, the MHHP is a fascinating case that challenges both halves of the term “community archives.” This study uses semi-structured interviews with MHHP volunteers and Morningside researchers to explore themes of volunteer motivation, competing values of privacy and access, sustainability and independence, and repatriation.

description: Restricted repetitive behaviors are core symptoms of autism spectrum disorders (ASDs). The range of symptoms encompassed by the repetitive behavior domain includes lower-order stereotypy and self-injury, and higher-order indices of circumscribed interests and cognitive rigidity. Heterogeneity in clinical ASD profiles suggests that specific manifestations of repetitive behavior reflect differential neuropathology. The present studies utilized a set of phenotyping tasks to determine a repetitive behavior profile for the C58/J mouse strain, a model of ASD core symptoms. In an observational screen, C58/J demonstrated overt motor stereotypy, but not over-grooming, a commonly-used measure for mouse repetitive behavior. Amphetamine did not exacerbate motor stereotypy, but had enhanced stimulant effects on locomotion and rearing in C58/J, compared to C57BL/6J. Both C58/J and Grin1 knockdown mice, another model of ASD-like behavior, had marked deficits in marble-burying. In a nose poke task for higher-order repetitive behavior, C58/J had reduced holeboard exploration and preference for non-social, versus social, olfactory stimuli, but did not demonstrate cognitive rigidity following familiarization to an appetitive stimulus. Analysis of available high-density genotype data indicated specific regions of divergence between C58/J and two highly-sociable strains with common genetic lineage. Strain genome comparisons identified autism candidate genes, including Cntnap2 and Slc6a4, located within regions divergent in C58/J. However, Grin1, Nlgn1, Sapap3, and Slitrk5, genes linked to repetitive over-grooming, were not in regions of divergence. These studies suggest that specific repetitive phenotypes can be used to distinguish ASD mouse models, with implications for divergent underlying mechanisms for different repetitive behavior profiles.

description: To bridge the gap in the literature regarding the emotional experience of African Americans researching their genealogy, the researcher conducted two to three semi-structured interviews utilizing a co-design methodology.  After the interviews, the participants analyzed the collected data with the researcher to create a collaborative and more accurate conclusion, empowering the participants to tell their own stories.  This study finds that the participants interviewed had negative experiences with formal recordkeeping practices regarding enslaved people and felt positive emotions by reclaiming their family tree through their research.  In the future, the researcher suggests dedicating more time to each participant to ensure their unique stories are more accurately conveyed, but found immense value in the partnership and trust cultivated through this research process.

description: Autonomic responses, including changes in heart rate and respiratory sinus arrhythmia (RSA) can provide indications of emotional reactivity to social stimuli in mammals. We have previously reported that male prairie voles (Microtus ochrogaster) spontaneously care for unfamiliar infants, showing a robust and sustained increase in heart rate in the presence of a pup, thus providing an opportunity to examine the physiology of care-giving in reproductively naïve animals. However, the purpose of such heart rate increases has not been explained by previous efforts. In the present study, we first compared male and female prairie vole cardiac responses in the presence of a pup and found no evidence of sex differences in heart rate or RSA. Using male prairie voles, we then examined the characteristics of pups that were capable of eliciting physiological responses, including age of the pup and pup odors. As prairie vole pups increased in age they vocalized less and there was an associated decline in alloparental cardioacceleration. Exposure to pup-related odors induced cardioacceleration in adult males and this effect also diminished with increasing pup age. Finally, we were able to block the cardioacceleratory effect when the testing environment was warmed to a temperature of 36° C [versus ambient room temperature (approximately 22° C)]. These findings suggest that pup-induced cardioacceleration is a robust phenomenon across alloparental prairie voles of both sexes, and depends on multi-modal processing of different stimuli from the pups. Young pups require care-giving behavior, which appears to drive cardioacceleration in the alloparent. This study also supports the usefulness of autonomic measures in the evaluation of social experiences.

description: Cross-fostering studies suggest cocaine-induced deficits in maternal behavior could be associated with altered behavior of offspring following prenatal cocaine-exposure. Neonatal vocalizations are an important offspring cue facilitating early interactions between dam and rodent pup offspring and have been shown to be altered following prenatal cocaine-exposure. It is unclear how variations in acoustic parameters of USVs impact maternal behavior and the mechanism(s) underlying these processes. The present study examined differences in cocaine-exposed and control rodent dam maternal preference of cocaine-exposed or untreated pups in a dual choice apparatus. Relationship of preference-like behavior with pup USVs and dam oxytocin expression was explored. Gestational cocaine-exposure interfered with preference-like behavior of dams on postpartum day 1 with cocaine-exposure associated with decreased time spent on the cocaine-exposed pup side compared to the control pup side, and decreases in preference-like behavior associated in part with decreased number of USVs being emitted by cocaine-exposed pups. On postpartum day 5, decreased oxytocin expression in the medial preoptic area was associated with altered preference-like behavior in cocaine-exposed dams, including frequency and latency to touch/sniff pups. Results indicate cocaine’s effects on the mother-infant relationship is likely synergistic, in that cocaine influences mother and offspring both independently and concertedly and that variations within pup vocalizations and the oxytocin system may be potential mechanism(s) underlying this synergistic relationship during the postpartum period.

description: Transcranial direct current stimulation (tDCS) modulates excitability of motor cortex. However, there is conflicting evidence about the efficacy of this non-invasive brain stimulation modality to modulate performance on cognitive tasks. Previous work has tested the effect of tDCS on specific facets of cognition and executive processing. However, no randomized, double-blind, sham-controlled study has looked at the effects of tDCS on a comprehensive battery of cognitive processes. The objective of this study was to test if tDCS had an effect on performance on a comprehensive assay of cognitive processes, a standardized intelligence quotient (IQ) test. The study consisted of two substudies and followed a double-blind, between-subjects, sham-controlled design. In total, 41 healthy adult participants completed the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) as a baseline measure. At least one week later, participants in substudy 1 received either bilateral tDCS (anodes over both F4 and F3, cathode over Cz, 2mA at each anode for 20 minutes) or active sham tDCS (2mA for 40 seconds), and participants in substudy 2 received either right or left tDCS (anode over either F4 or F3, cathode over Cz, 2mA for 20 minutes). In both studies, the WAIS-IV was immediately administered following stimulation to assess for performance differences induced by bilateral and unilateral tDCS. Compared to sham stimulation, right, left, and bilateral tDCS reduced improvement between sessions on Full Scale IQ and the Perceptual Reasoning Index. This demonstration that frontal tDCS selectively degraded improvement on specific metrics of the WAIS-IV raises important questions about the often proposed role of tDCS in cognitive enhancement.

description: Previous research has explored how Wikipedia contains instances of gender bias and exclusionary practices in their policies. This content analysis of 39 transgender scientists’ biographies and revision histories extends the notion of gender bias beyond the traditional binary approach to gender. Transgender scientists’ biographies and revision histories often include their deadnames, wrong pronouns, and acts of vandalism. In concurrence with previous research, transgender scientists’ pages are monitored and produced by groups of editing communities experiencing emotional and unseen labor. This research argues that Wikipedia must update their policies on deadnaming transgender scholars despite current notability concerns.

description: Arithmetic operations can be defined in various ways, even if one assumes commutativity and associativity of addition and multiplication, and distributivity of multiplication with respect to addition. In consequence, whenever one encounters `plus' or `times' one has certain freedom of interpreting this operation. This leads to some freedom in definitions of derivatives, integrals and, thus, practically all equations occurring in natural sciences. A change of realization of arithmetic, without altering the remaining structures of a given equation, plays the same role as a symmetry transformation. An appropriate construction of arithmetic turns out to be particularly important for dynamical systems in fractal space-times. Simple examples from classical and quantum, relativistic and nonrelativistic physics are discussed, including the eigenvalue problem for a quantum harmonic oscillator. It is explained why the change of arithmetic is not equivalent to the usual change of variables, and why it may have implications for the Bell theorem.

description: Cannabinoid signaling via the CB1 receptor modulates the effects of drugs of abuse and the response to exposure to stressors. In addition, exposure to stressors can alter the effects of drugs of abuse. The present study examined the effects of exposure to chronic unpredictable stress (CUS) in CB1 receptor knockout mice (CB1 KO) and their wild-type (WT) littermates, using cocaine conditioned place preference (CPP) to compare their response to cocaine. Mice were untreated or exposed to two weeks of CUS. Following this period, the acquisition of a cocaine CPP was examined with one of three doses (3.2, 10.0 or 17.0 mg/kg) of cocaine. Untreated CB1 KO and WT mice both acquired the cocaine CPP; however, exposure to CUS enhanced the acquisition of the cocaine CPP in CB1 KO mice, but did not significantly alter the effects of cocaine in WT mice. Taken together, these findings support previous evidence suggesting a role for the CB1 receptor in the response to stress as well as in the effects of cocaine.

description: We provide evidence for the mapping of critical spin-1 chains, in particular the SU(3) symmetric bilinear-biquadratic model with additional interactions, to free boson theories using exact diagonalization and the density matrix renormalization group algorithm. Using the correspondence with a conformal field theory with central charge c=2, we determine the analytic formulae for the scaling dimensions in terms of four Tomonaga-Luttinger liquid parameters. By matching the lowest scaling dimensions, we numerically calculate these field-theoretic parameters and track their evolution as a function of the parameters of the lattice model.

Intellectual freedom
Censorship

description: Policies and processes for library material reconsideration are essential to collection criteria, especially given the current climate in the US around book challenges and bans. Yet few studies to date look at the prevalence of policies and if there are consistencies among existing reconsideration processes or if they are publicly accessible. To fill this gap, this project explores whether library reconsideration policies are readily accessible in public libraries throughout North Carolina, the consequences of a process absence, and the possibilities of what an updated (and transparent) policy would mean for intellectual freedom. Relying on data collected from a random cluster sample of 20 North Carolina public county libraries, this study analyzes the availability (or absence) of a policy and if similar themes existed among available policies.

description: The present study examined the effects of the mGluR1 antagonist JNJ16259685 (JNJ) and the mGluR5 antagonist MPEP alone and in combination with morphine in two acute pain models (hotplate, warm water tail-withdrawal), and a persistent, inflammatory pain model (capsaicin). In the hotplate and warm water tail-withdrawal procedures, JNJ and MPEP were ineffective when administered alone. In both procedures, JNJ potentiated morphine antinociception. In the hot plate procedure, MPEP potentiated morphine antinociception at the highest dose examined, whereas in the warm water tail-withdrawal procedure MPEP attenuated morphine antinociception at a moderate dose and potentiated morphine antinociception at a high dose. For both JNJ and MPEP, the magnitude of this morphine potentiation was considerably greater in the hotplate procedure. In the capsaicin procedure, the highest dose of MPEP produced intermediate levels of antihyperalgesia and also attenuated the effects of a dose of morphine that produced intermediate levels of antihyperalgesia. In contrast, JNJ had no effect when administered alone in the capsaicin procedure and did not alter morphine-induced antihyperalgesia. The present findings suggest that the effects produced by mGluR1 and mGluR5 antagonists alone and in combination with morphine can be differentiated in models of both acute and persistent pain.

description: This study explored the involvement of N-methyl-D-aspartate (NMDA) in the effects of mu opioid agonists. A hot plate procedure was used to assess antinociception and tolerance in mice in which the NR1 subunit of the NMDA receptor was reduced (knocked down, KD) to approximately 10% and in mice treated with the NMDA antagonist, LY235959 [(−)-6-phosphonomethyl-deca-hydroisoquinoline-3-carboylic acid]. The mu opioid agonists, morphine, l-methadone and fentanyl, were approximately 3-fold less potent in the NR1 KD mice than in wild type (WT) controls; however, the development of morphine tolerance and dependence did not differ markedly in the NR1 KD and WT mice. Acute administration of the NMDA antagonist, LY235959 produced dose-dependent, leftward shifts in the morphine dose-effect curve in WT mice, but not in the NR1 KD mice. Chronic administration of LY235959 during the morphine tolerance regimen did not attenuate the development of tolerance in the NR1 KD nor the WT mice. These results indicate that the NR1 subunit of the NMDA receptor does not play a prominent role in mu opioid tolerance.

description: An orbit polytope is the convex hull of an orbit under a finite group $G \leq \operatorname{GL}(d,\mathbb{R})$. We develop a general theory of possible affine symmetry groups of orbit polytopes. For every group, we define an open and dense set of generic points such that the orbit polytopes of generic points have conjugated affine symmetry groups. We prove that the symmetry group of a generic orbit polytope is again $G$ if $G$ is itself the affine symmetry group of some orbit polytope, or if $G$ is absolutely irreducible. On the other hand, we describe some general cases where the affine symmetry group grows. We apply our theory to representation polytopes (the convex hull of a finite matrix group) and show that their affine symmetries can be computed effectively from a certain character. We use this to construct counterexamples to a conjecture of Baumeister et~al.\ on permutation polytopes [Advances in Math. 222 (2009), 431--452, Conjecture~5.4].

description: We tested the hypothesis that the irreversible gamma-amino butyric acid (GABA) transaminase inhibitor, γ-vinyl GABA (Vigabatrin; VGB) would reduce ethanol reinforcement and enhance the discriminative stimulus effect of ethanol, effectively reducing ethanol intake. The present studies used adult C57BL/6J (B6) mice in well-established operant, two-bottle choice consumption, locomotor activity and ethanol discrimination procedures, to examine comprehensively the effects of VGB on ethanol-supported behaviors. VGB dose-dependently reduced operant responding for ethanol as well as ethanol consumption for long periods of time. Importantly, a low dose (200 mg/kg) of VGB was selective for reducing ethanol responding without altering intake of food or water reinforcement. Higher VGB doses (>200 mg/kg) still reduced ethanol intake, but also significantly increased water consumption and, more modestly, increased food consumption. While not affecting locomotor activity on its own, VGB interacted with ethanol to reduce the stimulatory effects of ethanol on locomotion. Finally, VGB (200 mg/kg) significantly enhanced the discriminative stimulus effects of ethanol as evidenced by significant left-ward and up-ward shifts in ethanol generalization curves. Interestingly, VGB treatment was associated with slight increases in blood ethanol concentrations. The reduction in ethanol intake by VGB appears to be related to the ability of VGB to potentiate the pharmacological effects of ethanol.
