Maternal Care and Control as Mediators in the Relationship Between Mothers’ and Adult Children’s Psychosocial Problems

The current research investigated the relationship between mothers’ and adult children’s psychosocial problems through two different aspects of maternal interactions. Data were collected from family triads (N = 286), including a mother, a child, and a sibling. Mothers and their adult children completed measures of depression, loneliness, and self-esteem. The assessment of the maternal interaction variables (i.e., maternal care and maternal control) involved the perspectives of a sibling to minimize common method variance. Results partially supported the hypothesized model, wherein maternal care (but not maternal control) mediated the relationship between mothers’ depression, loneliness, and self-esteem to that of their children. Specifically, mothers who reported higher levels of psychosocial problems had children who reported that their mothers were less caring and, in turn, less maternal care was associated with higher levels of psychosocial problems in their young adult children.

Wearable nanosensor system for monitoring mild traumatic brain injuries in football players

Football players are more to violent impacts and injuries more than any athlete in any other sport. Concussion or mild traumatic brain injuries were one of the lesser known sports injuries until the last decade. With the advent of modern technologies in medical and engineering disciplines, people are now more aware of concussion detection and prevention. These concussions are often overlooked by football players themselves. The cumulative effect of these mild traumatic brain injuries can cause long-term residual brain dysfunctions. The principle of concussion is based the movement of the brain in the neurocranium and viscerocranium. The brain is encapsulated by the cerebrospinal fluid which acts as a protective layer for the brain. This fluid can protect the brain against minor movements, however, any rapid movements of the brain may mitigate the protective capability of the cerebrospinal fluid. In this paper, we propose a wireless health monitoring helmet that addresses the concerns of the current monitoring methods - it is non-invasive for a football player as helmet is not an additional gear, it is efficient in performance as it is equipped with EEG nanosensors and 3D accelerometer, it does not restrict the movement of the user as it wirelessly communicates to the remote monitoring station, requirement of individual monitoring stations are not required for each player as the ZigBee protocol can couple multiple transmitters with one receiver. A helmet was developed and validated according to the above mentioned parameters.
Does Location Matter? The Efficiency of Request Propagation Based on Location in Online Social Networks

The centrality metrics such as Closeness and Betweenness in Online Social Network (OSN) determine how much end-to-end delay and queue-load of a node can have as a source or as a destination through Social Routing. Experimentally, we find that nodes with high Out-Closeness centrality in OSN suffer from high end-to-end delay as a target, but not as a source. We show that the cause of this end-to-end delay is that most nodes with high Out-Closeness centrality have low In-Closeness centrality. Moreover, we show that the increase in the local In-Degree centrality will increase the global In-Closeness centrality. We also find that the promised level to increase the In-Closeness centrality of a node is its Friends of Friends-Of-Friends (Level-3). An agent-based Model for Social Routing is proposed and a set of large-scale Google+ Graphs are used. A simulation study is also completed by propagating a set of requests in different societies with different routing schemes and diverse queue disciplines, in order to compare the average end-to-end delays from the source and target perspectives.
Symposium 2: Flexible Endoscopic Surgery-Indications and Techniques

A domestic questionnaire survey was done to collect information on the use of the endoscopy for the removal of foreign bodies in the tracheo-bronchial tree or the esophagus. Based on the survey and the author's own experiences, this paper discusses the advantages and disadvantages of the rigid endoscopes as well as flexible ones. An appropriate choice for removal of the foreign body is also discussed.The flexible endoscope provides a better view, while the rigid endoscope is convenient for the removal of the foreign body. In addition, the flexible endoscope can access to the foreign body caught in distal bronchi or stomach that can't be reached by the rigid apparatus. Considering these advantages and disadvantages of each type of endoscope, the best choice should be made to remove foreign bodies safely and quickly.
Structural realism beyond physics.

Abstract The main purpose of this paper is to test structural realism against (one example from) the historical record. I begin by laying out an existing challenge to structural realism – that of providing an example of a theory exhibiting successful structures that were abandoned – and show that this challenge can be met by the miasma theory of disease. However, rather than concluding that this is an outright counterexample to structural realism, I use this case to show why it is that structural realism, in its current form, has trouble dealing with theories outside physics. I end by making some concrete suggestions for structural realists to pursue if, indeed, they are serious about extending structural realism to other domains.
Degradation of Trichloroethylene by Methanotrophic Bacteria in a Laboratory Column of Saturated Aquifer Material

A laboratory experiment was designed to investigate the biotransformation of trichloroethylene (TCE) by bacteria using methane as a primary substrate under conditions simulating a contaminated aquifer. Solid material was acquired aseptically from an uncontaminated shallow confined aquifer and packed in glass columns. The relationship between the methane and oxygen supplied, bacterial growth, and TCE transformation was examined in an attempt to optimize a potentially applicable process of in situ treatment of ground water. Approximately 20 percent of the 14C-labelled TCE, at an initial concentration of 50 µg/L, was transformed to CO2. A five-fold increase in the rate at which methane and oxygen were supplied to the columns resulted in no substantial increase in TCE transformation. The sorption of TCE onto aquifer solids may have obscured treatment differences. Addition of hydrogen peroxide as the source of oxygen caused a decrease in methane utilization, although the impact on TCE transformation is not yet clear.
Geometric Approach to Biosequence Analysis

Tools that effectively analyze and compare sequences are of great importance in various areas of applied computational research, especially in the framework of molecular biology. In the present paper, we introduce simple geometric criteria based on the notion of string linearity and use them to compare DNA sequences of various organisms, as well as to distinguish them from random sequences. Our experiments reveal a significant difference between biosequences and random sequences the former having much higher deviation from linearity than the latter as well as a general trend of increasing deviation from linearity between primitive and biologically complex organisms. The proposed approach is potentially applicable to the construction of dendograms representing the evolutionary relationships among species.
Dance/Movement Therapists of Color in the ADTA: The First 50 Years

One of a collection of six scholarly essays solicited by this journal to celebrate the first half-century of the American Dance Therapy Association, this paper looks at current practices in dance therapy education, clinical practice, and professional leadership as inclusive of, or excluding to, individuals who identify as a person of color. Recommendations for more inclusive attitudes and practices are provided.
Caring for Dying Patients in the Nursing Home: Voices From Frontline Nursing Home Staff

Abstract Context Nursing homes are an important site for end-of-life care, yet little is known about the perspectives of the frontline staff who provide a majority of this care. Objective To describe, from the staff perspective, positive/negative experiences related to caring for dying residents. Methods Qualitative analysis using survey data from staff working in 52 Indiana nursing homes. Results A total of 707 frontline staff who provide nursing, nurse aide, and social work services responded to open-ended prompts. Study data included responses to open-ended prompts asking participants to describe one positive experience and one negative experience caring for a dying patient. A thematic content analysis was conducted using the constant-comparative method. Respondents were largely female (93%), white (78%), 31–50 years (42%), and 53% had >5 years of nursing home work experience. Experiences were described from three perspectives: 1) first-hand experiences, 2) observed experiences of dying patients, and 3) observed experiences of family members. Selected themes for positive experiences include the following: creating close bonds; good patient care; involvement of hospice; being prepared; and good communication. Selected themes for negative experiences consisted of the following: challenging aspects of care; unacknowledged death; feeling helpless; uncertainty; absent family; painful emotions; and family discord. Conclusion Findings reveal the richness and many complexities of providing end-of-life care in nursing homes and have implications for improving staff knowledge, coordination of care with hospice, and social support for patients.
Preparing a workforce to effectively reuse data

For centuries, library and information science professionals have been responsible for curating and preserving access to information resources. The last few decades have seen an unprecedented change in how new knowledge is created, disseminated and reused both within academe and industry, which provides new opportunities to intervene within the data lifecycle. This paper documents efforts to create a graduate educational program that produces alum who understand both the social and technical aspects of data analytics and who can effectively employ data to address questions in academe and industry. We share perspectives gained from initial interviews with project partners who have data needs, and report on how those needs directly informed curricula development of the Socio-technical Data Analytics (SODA) program at the School of Information Sciences at the University of Illinois. We also provide a formative student evaluation of the program that was conducted to identify aspects that are successful, and those where further work is needed in order to help other schools who are developing similar programs that prepare a workforce who can effectively reuse data.
Distributed fictitious play for multi-agent systems with uncertainty

We consider a networked multi-agent system in which agents' actions and an unknown state of the environment affect the global well-being of the system. Agents have different and time varying beliefs on the state. As a consequence, when an agent chooses an action to execute, it is important for it to reason about what the beliefs of other agents may be and what are the consequent actions that other agents may take. We propose a decentralized solution based on the construction of empirical histograms of past actions using shared empirical histograms by neighboring agents and the use of best responses to the utility expectation with respect to the constructed histograms and the state belief. This algorithmic behavior is a variation of the fictitious play algorithm and is shown to be asymptotically optimal in the sense that if agents move towards a common belief on the state fast enough, their behavior is a Nash equilibrium of the game with the utility given by the expectation of the global objective with respect to the common belief. We numerically analyze the algorithm in a target covering game.
Telecommunication system design for interplanetary CubeSat missions: LunaH-Map

The1 Lunar Hydrogen Mapper (LunaH-Map) will be one of 13 CubeSats to launch on the first integrated flight of NASA's Space Launch System and Orion spacecraft in 2018. The goal of the LunaH-Map mission is to map the hydrogen content of the entire South Pole of the moon, including permanently shadowed regions at high resolution. The spacecraft is a 6 U CubeSat and the main instrument is a neutron spectrometer which will be used to perform the measurements required to accomplish the primary science objective. Once LunaH-Map reaches the Moon, the spacecraft will perform a 60-day science mission, consisting of 141 science orbits during which the measurements will be taken. In the design of the LunaH-Map spacecraft, one of the main challenges is the telecommunication system as the spacecraft needs the ability to relay data during the long cruise phase and during the science phase. In addition, the telecommunication system needs to support the main navigation functions required to reach the Moon and to insert in the highly elliptical orbit required for the science phase. This paper covers the main aspects of the telecommunication design for the mission including: link and coverage analysis, waveform selection and spectral constraints, hardware selection and ground station coordination.
Orbital Coupling for Proof Mass Control in a Partially Drag-Free Satellite

Abstract Compensation of external forces was achieved with a drag-free satellite in 1972. If a mission only requires drag compensation in a single direction, its proof mass may be passively supported in the lateral directions. Modulation of the radial suspension force can be used to damp radial motions actively but a final state of orbital motion of the proof mass about the suspension centerline is possible. Methods of preventing this proof mass orbital condition from being a final state are discussed. For a locally oriented satellite with intrack drag-free control, the forward-vertical orbital coupling can be used to damp the proof mass orbital motion using the intrack drag compensating thrustors. This system has been breadboarded and simulated. Its effectiveness is compared with satellite mass center-suspension center separation, lateral external disturbing accelerations, and other effects which change the suspension to a non-central force field.

Using laboratory-generated biosolids to evaluate the microbial ecotoxicity of triclosan in a simulated land application scenario.

Land application accounts for approximately 50% of wastewater solids disposal in the USA. Yet, little is known regarding the ecological impacts of many non-regulated chemicals found in biosolids. In most previous studies aimed at assessing ecological impacts, a model biosolid is generated by spiking high concentrations of the target chemical into a soil or biosolid. This approach does not account for the interaction of the chemical of interest with the solids throughout the biosolids production process (a.k.a., aging) which may impact the bioavailability and, thus, ultimate toxicity of the chemical. In the present study, using a lab-scale wastewater and digestion treatment system, we generated biosolids which contained aged triclosan and compared ecological impacts to that of spiked biosolids. Ecotoxicity was assessed based on functional and community structure changes to soil denitrifiers, microorganisms critical to nitrogen cycling. A decrease in denitrifier abundance and diversity was observed in the aged biosolids at concentrations of 17.9 ± 1.93 μg/kg while decreases in activity were observed at 26.9 ± 4.6 μg/kg. In the spiked biosolids treatment, lower denitrifier abundance, diversity, and activity were observed at triclosan (TCS) concentrations of 68.6 ± 26.9 μg/kg. This difference suggests a need to better understand TCS bioavailability dynamics.
Interprofessional Education Perceptions of Dental Assisting and Radiologic Technology Students Following a Live Patient Experience

Health professions students are often unaware of other health care providers' roles or professional expertise due to most education taking place within their single profession. This pattern may be even more prevalent for baccalaureate and associate degree programs since most interprofessional education (IPE) occurs in predoctoral programs and, when IPE is incorporated into allied health professions education, it often utilizes simulation instead of live patient experiences. The aim of this study was to determine if radiologic technology and dental assisting students' perceptions changed regarding interprofessional practice and teamwork after an IPE activity with actual patients. The participants were students in the University of Southern Indiana (USI) radiologic technology and dental assisting programs. This mixed-methods pilot study conducted in 2017 collected quantitative and qualitative data from pre and post surveys, the researchers' observations of student interactions during live patient assessment and acquisition of panoramic images, and large-group discussion. Twenty-five of the 26 students who participated in the IPE program completed both pre and post surveys, for a 96% response rate. The results showed significant differences in the participants' perceptions from the pre to post surveys on a wide variety of survey items. Most notable were the positive changes in perceptions related to trust in judgment of others within their profession (p=0.001), relationships with other professions (p=0.002), and thinking highly of other professions (p=0.002). Overall, this study found that incorporating the IPE activity with a live patient into these radiologic technology and dental assisting programs improved the students' perceptions of other allied health professionals. Future research should include more participants to increase sample size and add quantitative data collection.
Mediators and Moderators of a Personalized Feedback Alcohol Intervention for Nonstudent Emerging Adult Drinkers.

BACKGROUND The main objective of this study was to test proposed mediators and moderators of a personalized feedback alcohol intervention (PFI) on alcohol use. Data for the current investigation came from an earlier randomized controlled trial of a PFI targeted for nonstudent heavy drinkers between 18 and 25 years. METHODS Participants were 164 (65.9% men) drinkers recruited from the community. They were randomly assigned to either a single-session PFI or an assessment-only (AO) control group. Follow-up assessments at 1 and 3 months were included for analysis. RESULTS Perceived drinking norms mediated the intervention effect on quantity, frequency, and peak drinking; 2 dimensions of protective behavioral strategies (PBS) mediated the intervention effect on peak drinking; and drinking to cope motives did not mediate any drinking outcomes. Of the moderating factors examined (i.e., norms, PBS, drink to cope motives, age, gender), only PBS related to serious harm reduction moderated intervention impact. Specifically, for those high in serious harm reduction PBS at baseline, postintervention reductions in drinking were stronger for the PFI group compared to AO. CONCLUSIONS Overall, findings highlight the importance of correcting misperceived drinking norms and addressing the use of specific PBS in brief interventions. The knowledge gained from this study represents an important step toward minimizing drinking-related harms that are disproportionately experienced by those with lower educational attainment.
Convergence of σ-Fields and Applications to Mathematical Economics

A natural and general way to model information in a microeconomic system is to specify it as a sub-σ-field (of the σ-field of events, or measurable subsets of the set of states of the world). Several apparently different definitions of convergence have been introduced. For continuous time trading models, relationships between continuous information (assumed to be increasing and right continuous) and various continuity properties of asset prices have been studied by Harrison and Huang. For a static general equilibrium pure exchange economy, the information topology advocated by Allen yields continuity of microeconomic behavior (i.e., continuous dependence of agents’ demand functions on their state dependent utilities, initial endowments, and information) and of the value of information. Additional convergence notions for σ-fields appear in the probability theory literature. This paper compares these convergence notions and analyzes when it can be said that one is weaker than another.
Incorrect and Beautiful Anatomies: Becomings, Immanence, and Transspecies Bodies in the Art of Roberto Fabelo

In a series of ink drawings over the pages of a nineteenth-century medical encyclopedia containing illustrations of human anatomy, the contemporary Cuban artist, Roberto Fabelo, produces a catalogue of figures displaying zoological physiognomies. Overlapping the uniform incisions of the text’s original engravings with sketchy, gestural cross-hatching, Fabelo transforms tissue, capillaries, muscles and bone into aesthetic material. While these images produce hybrid morphologies on an iconographic level, I aim to demonstrate that the crossing of species identities does not simply remain at the safe distance of the fantastic. In the juxtaposition of clinical, two-dimensional illustrations and volumetric chiaroscuro we can observe agitated lines that subvert the privileged position of the human. Fabelo’s compositions undermine representational techniques that have served as the means of producing taxonomies.

Role of Insulin-Like Growth Factor Receptors in Cancer Signaling

The insulin-like growth factor signaling system has been implicated in cancer etiology, progression, and metastasis. This signaling system involves a network of highly related ligands and receptors. Targeting of this system is complex; multiple receptors, including the insulin receptor, are involved. Further, holo- and hybrid receptors must be considered when considering therapeutic strategies. This review will evaluate the signaling pathways mediated by this system.
Epigenetic changes in the mammalian paternal germ line

Abstract Besides genetic information, sperm cells also deliver epigenetic information from the father to the embryo. These two kinds of paternal information are essential determinants for embryonic development and health of the offspring. Epigenetic information may reflect environmental and lifestyle circumstances that each individual experiences during his lifetime. Exogenous alterations of epigenetic information occur mainly during certain time windows during sperm development when the male epigenome is particularly susceptible. Opportunities exist during early phases of life in utero, during puberty, and in the adult, so that epigenetic marks reflect phenotypic adaptations over a lifetime. The marks can be transmitted to future generations in the form of epigenetic information in sperm. This chapter reviews carriers of mammalian sperm epigenetic information, such as nuclear architecture, DNA methylation, the histone code, and small noncoding RNAs, and briefly discusses how they are subject to change by environmental influence.

Optimum Priority Class Selection Under Wi-Fi&#x002F;LTE Coexistence

Wi-Fi and LTE standards define several traffic classes to prioritize applications based on their requirements. When these technologies coexist in unlicensed bands, the class selection of one system impacts the performance of the other. In this paper, we investigate how the traffic class selection affects the delay for completing the transmission of a fixed number of bits. We develop an analytical framework which characterizes the average delay under Wi-Fi&#x002F;LTE coexistence. Our framework allows us to optimize the class selection for a Wi-Fi or LTE station based on the traffic class selected by the surrounding stations and minimize the average delay. We show that operating at a high priority class does not always minimize delay. Under certain contention and class selection conditions, a low priority class reduces the collision probability while increasing the airtime once the channel is captured. This leads to a lower overall delay. We provide numerical examples that demonstrate the inherent tradeoffs between the traffic class parameters.
The English lexicon mirrors functional brain activation for a sensory hierarchy dominated by vision and audition: Point-counterpoint

The meanings of most open class words are suffused with sensory and affective features. A word such as beach, for example, evokes polymodal associations ranging from gritty sand (tactile) and crashing waves (auditory) to the distinctive smell of sunscreen (olfactory). Aristotle argued for a hierarchy of the senses where vision and audition eclipse the lesser modalities of odor, taste, and touch. A direct test of Aristotle's premise was recently made possible with the establishment of the Lancaster Sensorimotor Norms (2019), a crowdsourced database cataloging sensorimotor salience for nearly 40,000 English words. Neurosynth, a metanalytic database of functional magnetic resonance imaging studies, can potentially confirm if Aristotle's sensory hierarchy is reflected in functional activation within the human brain. We correlated sensory salience of English words as assessed by subjective ratings of vision, audition, olfaction, touch, and gustation (Lancaster Ratings) with volumes of cortical activation for each of these respective sensory modalities (Neurosynth). English word ratings reflected the following sensory hierarchy: vision > audition > haptic > olfaction ≈ gustation. This linguistic hierarchy nearly perfectly correlated with voxel counts of functional activation maps by each sensory modality (Pearson r=.99). These findings are grossly consistent with Aristotle's hierarchy of the senses. We discuss implications and counterevidence from other natural languages.
Repression of the transcriptional activity of ERRα with sequence-specific DNA-binding polyamides

The orphan nuclear receptors estrogen-related receptors (ERRs) bind to the estrogen-related receptor response element (ERRE) to regulate transcriptional programs in cellular metabolism and cancer cell growth. In this study, we evaluated the potential for a pyrrole-imidazole polyamide to block ERRα binding to ERREs to inhibit gene expression. We demonstrated that the ERRE-targeted polyamide 1 blocked the binding of ERRα to the consensus ERRE and reduced the transcriptional activity of ERRα in cell culture. We further showed that inhibiting ERRα transcriptional activity with polyamide 1 led to reduced mitochondrial oxygen consumption, a primary biological effect regulated by ERRα. Finally, our data demonstrated that polyamide 1 is an inhibitor for cancer cell growth.
Poggio Bracciolini and the Re(dis)covery of Antiquity: Textual and Material Traditions : Proceedings of the Symposium Held at Bryn Mawr College on April 8-9, 2016

This collection draws strength from its cross-disciplinarity, featuring contributions by scholars who investigate Bracciolini's contribution to many fields of knowledge in the Western tradition, spanning across politics and historiography, material and print culture, philology and manuscript studies, calligraphy and palaeography. The essays touch upon intertwined aspects of early Renaissance in its recovery of the classical tradition where the concept of humanitas extends to the manuscript itself. “This distinguished collection of essays adds a wealth of scholarly detail to our understanding of the myriad-minded Renaissance humanist Poggio Bracciolini. And, in doing so, it also managed to capture much of the range and flavour of this extraordinary figure: his learning, his passionate interest in antiquity, his civic pride, and his brilliance in calligraphic design, as well as his ceaseless self-promotion , his enmities, his taste for obscenity, and his penchant for moralizing. Poggio's startling energy and the energy of the whole period course through these pages" (Stephen Greenblatt)
Geminal replacement models based on AGP

The antisymmetrized geminal power (AGP) wave function has a long history and is known by different names in various chemical and physical problems. There has been recent interest in using AGP as a starting point for strongly correlated electrons. Here, we show that in a seniority-conserving regime, different AGP-based correlator representations based on generators of the algebra, killing operators, and geminal replacement operators are all equivalent. We implement one representation that uses number operators as correlators and has linearly independent curvilinear metrics to distinguish the regions of Hilbert space. This correlation method called J-CI provides excellent accuracy in energies when applied to the pairing Hamiltonian.

Understanding and detecting server-side request races in web applications

Modern web sites often run web applications on the server to handle HTTP requests from users and generate dynamic responses. Due to their concurrent nature, web applications are vulnerable to server-side request races. The problem becomes more severe with the ever-increasing popularity of web applications. We first conduct a comprehensive characteristic study of 157 real-world server-side request races collected from different, popular types of web applications. The findings of this study can provide guidance for future development support in combating server-side request races. Guided by our study results, we develop a dynamic framework, ReqRacer, for detecting and exposing server-side request races in web applications. We propose novel approaches to model happens-before relationships between HTTP requests, which are essential to web applications. Our evaluation shows that ReqRacer can effectively and efficiently detect known and unknown request races.
Trisulfur radical anion S3•--A major carrier for platinum in hydrothermal fluids.

Platinum (Pt) and other platinum group elements (PGE), including palladium (Pd), iridium (Ir), rhodium (Rh), ruthenium (Ru), and osmium (Os), have many advantageous characteristics, including catalytic properties, corrosion resistance, and high melting points (Table 1), which lend themselves to various applications ranging from automotive catalysts to pharmaceutics to use in jewelry (1). In particular, the chemical behavior of PGE is quite unique: On the one hand, they are inert and highly resistant to corrosion by most chemicals; on the other hand, they can serve as catalysts, accelerating the rates of many petrochemical reactions. However, PGE have very low elemental abundances in Earth's crust, all at part per billion (ppb) levels (Table 1) (2, 3). Hence, PGE-bearing ore deposits are a critical resource, and their extracted PGE metals are highly sought after by modern industries. To effectively utilize sparse PGE resources, it is essential to understand the formation of PGE ore deposits for their targeted exploration and to develop efficient chemical approaches for PGE extraction and separation. View this table: Table 1. Some characteristics of PGE and associated Au Although the natural abundances of PGE are low, fortunately, they are not evenly distributed within Earth and other planets. Because of their aversion to bonding with oxygen and their high affinity for reduced sulfur, PGE tend to either occur in the metallic state (siderophile, metal loving) or bond with sulfur or other group VA and VIA ligands (chalcophile, sulfur loving) to form mineral components (4). Consequently, PGE are concentrated in core-forming Fe-Ni alloys and in sulfide phases of PGE-bearing ore deposits (5). This distinct behavior of PGE, as well as their radioisotope systematics, can serve as indicators of many geological processes such as early solar system evolution, and planetary differentiation and formation (6). Of critical importance to PGE-bearing ore deposits is the enrichment of PGE … [↵][1]1Email: hxu{at}lanl.gov. [1]: #xref-corresp-1-1
Late Breaking Results: Parallelizing Net Routing with cGANs

Obstacle-avoiding multiterminal net routing approach is proposed. The approach is inspired by deep learning image processing. The key idea is based on training a conditional generative adversarial network (cGAN) to interpret a routing task as a graphical bitmap and consequently map it to an optimal routing solution represented by another bitmap. The system is implemented in Python/Keras, trained on synthetically generated data, evaluated on typical high-resolution benchmarks, and compared with state-of-the-art traditional deterministic and deep learning solutions. The proposed system yields between 10.75x and 83.33x speedup over the traditional router without wirelength overhead due to effective parallelization on GPU hardware.
Modulation of non-NMDA receptor gating by auxiliary subunits

During the past decade, considerable evidence has accumulated that non-NMDA glutamate receptors (both AMPA and kainate subtypes) are modulated by the association of the core tetrameric receptor with auxiliary proteins that are integral components of native receptor assemblies. This short review focuses on the effect of two types of auxiliary subunits on the biophysical properties and kinetic behaviour of AMPA and kainate receptors at the level of single receptor molecules. Type I transmembrane AMPA receptor proteins increase the number of AMPA receptor openings that result from a single receptor activation as well as the proportion of openings to conductance levels above 30 pS, resulting in larger peak ensemble currents that decay more slowly and bi-exponentially. Co-expression of Neto1 and 2 with pore-forming kainate receptor subunits also increases the duration of bursts and destabilizes desensitized states, resulting in a rapid component of recovery and clusters of bursts that produce a slow component in desensitization decays. The distinct gating seen in the presence of auxiliary subunits reflects slow switching between gating modes with different single-channel kinetics and open probability. At any given time, the relative proportions of receptors in each gating mode determine both the shape and the amplitude of synaptic currents.
Supporting self-evaluation in local government via KDD

Self-evaluation is a form of empowerment evaluation that is collaborative and participatory. Through self-evaluation, a county social services agency, with the assistance of experts, can design, monitor, and improve indicators that ultimately improve the outcomes that are important in their local community. A key element to the self-evaluation efforts is the availability of timely and accurate data that appropriately measure the outcomes of interest. However, many of the local agencies lack the resources to collect and analyze the data for such evaluations. Furthermore, it would be easier to have consistency across similar outcomes in different local governments if the state provided the technical assistance for such efforts. In this paper, we discuss a successful case study in which the North Carolina Department of Health and Human Services (NC-DHHS) in partnership with the University of North Carolina at Chapel Hill School of Social Work (UNCCH) used Knowledge Discovery and Data mining (KDD) technology to effectively support these self-evaluation efforts at the local level in child welfare. We present the key elements of the KDD information system built on the child welfare program in North Carolina.
Technetium Sorption in Surface Soils

Technetium from a number of sources has the potential for entering soils in initially volatile or solubilised forms [1,2]. Several assessments [3] have suggested that subsequent soil solubility and uptake by plants will be important factors in governing Tc radiation dose to man. However, prediction of Tc behaviour in soils and availability to plants is complicated by its complex chemistry relative to soil processes.
3-Substituted thietane derivatives

Abstract Stereochemical assignments could be made for a series of 3-substituted thietane 1-oxides from their NMR spectra. Both isomers appear to reside in conformations with the ring substituent equatorial. The cis isomer (equatorial SO bond) is characterized by a large chemical shift difference for the α-methylene hydrogens. The trans isomer is characterized by a significant deshielding of the β-hydrogen (relative to cis isomer, not relative to the parent sulfide). The dominant conformations of 3,3-dimethylthietane 1-oxide and the corresponding 1-tosylimine have the SX bond equatorial. Stereochemical assignments were made to the α-methylene protons and were confirmed by benzene-induced shift data. As expected for a hydrogen anti to the “lone pair” on sulfur the axial hydrogen of the sulfoxide appeared at higher field, the same was not true for the sulfilimine. Significant stereoselective benzene-induced shifts observed for the N-tosylsulfilimine and N-tosylsulfoximine of 3,3-dimetbylthietane indicate that they may constitute a method of configuration assignment for such compounds.
Ontogenesis of the intestinal transport of biotin in the rat.

Developmental aspects of the intestinal transport of biotin were examined in suckling (16 day old) and weanling (24 day old) rats using the everted sac technique. The results were compared with those of adult rats previously reported by us using the same intestinal preparation. Transport of biotin was linear for 20 min of incubation in all age groups. Transport of biotin was significantly (p less than 0.05) lower in the jejunum than the ileum of suckling rats but was not significantly different in the jejunum and the ileum of weanling rats. In adult rats, biotin transport was significantly (p less than 0.01) higher in the jejunum than the ileum. In all age groups, transport of biotin in the jejunum was saturable at low concentrations (less than 10 microM) but linear at high concentrations. The apparent Km and Vmax of the saturable process showed a progressive increase from suckling to weanling to adult rats (apparent Km of 0.63, 2.49, and 3.37 microM; Vmax of 18.3, 44.7, and 124.4 pmol/g.min, respectively). On the other hand, the rate of transport by the nonsaturable process showed a progressive decrease with maturation (143.8, 111.6, and 87.5 pmol/g.min for suckling, weanling, and adult rats, respectively). Transport of biotin in suckling and weanling rats was similar to that of adult rats in that it was Na+-, energy-, and temperature-dependent and inhibited by structural analogues. These results demonstrate that biotin transport undergoes clear maturational changes. These changes include a decrease in the affinity and an increase in the activity (and/or the numbers) of the transport carrier, a decrease in the rate of transport by the nonsaturable process, and a change in the preferential site of transport.
Efficacy of tranexamic acid in the treatment of idiopathic and non-functional heavy menstrual bleeding: A systematic review

Objective. To evaluate the efficacy of tranexamic acid in the treatment of idiopathic and non-functional heavy menstrual bleeding. Design. Systematic review. Population. Women with a diagnosis of idiopathic and non-functional heavy menstrual bleeding treated with tranexamic acid. Methods. Electronic searches were conducted in literature databases up to February 2011 by two independent reviewers. We included all trials involving the efficacy of tranexamic acid for the treatment of heavy uterine bleeding. Pregnant, postmenopausal and cancer patients were excluded. Main outcome measures. Effect of tranexamic acid treatment on objective reduction of menstrual bleeding and improvement in patient quality of life. Results. A total of 10 studies met our inclusion criteria. Available evidence indicates that tranexamic acid therapy in women with idiopathic menorrhagia resulted in 34–54% reduction in menstrual blood loss. Following tranexamic acid treatment, patient's quality-of-life parameters improved by 46–83%, compared with 15–45% for norethisterone treatment. When compared with placebo, tranexamic acid use significantly decreased the blood loss by 70% in women with menorrhagia secondary to an intrauterine device (p<0.001). Limited evidence indicated potential benefit in fibroid patients with menorrhagia. No thromboembolic event was reported in all studies analyzed. Conclusions. Available evidence indicates that tranexamic acid treatment is effective and safe, and could potentially improve quality of life of patients presenting with idiopathic and non-functional heavy menstrual bleeding. Data on the therapeutic efficacy of tranexamic acid in patients with symptomatic fibroids are limited, and further studies are therefore needed.
Correlation effects in pyrochlore iridate thin films grown along the [111] direction

Over the past few years, bulk pyrochlore iridates of the form ${A}_{2}{\mathrm{Ir}}_{2}{\mathrm{O}}_{7}$ (where $A$ is a rare earth element, Ir is iridium, and O is oxygen) have been studied as model systems for investigating the interplay of electronic correlations and strong spin-orbit coupling, particularly with the aim of finding correlation-driven topological phases. In this work, we use cellular dynamical mean field theory (CDMFT) to study effects of electronic correlations beyond Hartree-Fock theory in thin films of pyrochlore irradiates grown along the $[111]$ direction. We focus on the bilayer and trilayer systems, and compute the phase diagrams of these systems as a function of electron-electron interaction strength, which is modeled by an onsite Hubbard interaction. By evaluating the ${Z}_{2}$ invariant and Chern number using formulas based on the single-particle Green's function and the quasiparticle effective Hamiltonian, we show that onsite correlations can drive an interaction-induced topological phase transition, turning a time-reversal-invariant topological insulator and a nearly flat band metal to a correlated Chern insulator (CI) in bilayer and trilayer systems, respectively. By comparing with the Hartree-Fock results, the CDMFT results show that quantum fluctuations enhance the robustness of the interaction-driven CI phase in the thin films. Furthermore, our numerical analysis of the quasiparticle spectrum reveals that the topological phases we find in our many-body calculations are adiabatically connected to those in the single-particle picture.
TRANSMEMBRANE SIGNALING AND PHOSPHOINOSITIDES

Publisher Summary This chapter illustrates that inositol phospholipid metabolism can be monitored in plants but it must be done carefully to be able to interpret the results. 32 P i and myo [2- 3 H]inositol are the most common radioisotopes used to label the inositol phospholipids. 32 P i labels phospholipids, sugar phosphates, nucleotides, and, other cellular metabolites that can interfere with the analysis of the inositol phospholipids and inositol phosphates. myo [2- 3 H]inositol is a more selective means of labeling the inositol phospholipids and inositol phosphates in vivo than 32 P i. 32 P incorporation into phosphatidylinositol bisphosphate (PIP 2 ) saturates after approximately 10 min with the carrot cells. The major drawback to using short-term labeling is that the stimulus applied may affect [ 32 P] P i uptake or the levels of [ 32 P]ATP within the cell and thereby affect the recovery of [ 32 P]PIP or PIP 2 without affecting phospholipid turnover. In addition, differences in the uptake of the label among tissue samples prior to applying the stimulus are more pronounced with short-term labeling.
Prenatal sonographic detection of cardiac aneurysms and diverticula.

We describe three cases of isolated ventricular aneurysm or diverticulum detected antenatally, with subsequent prenatal serial study and postnatal followup. Two pregnancies with in utero left ventricular aneurysm, both involving the apex, were referred for fetal atrial arrhythmias at 28 and 25 weeks of gestation, respectively. The aneurysms had a saccular appearance and were thin-walled and hypokinetic. In a third pregnancy, referred for an abnormal fourchamber view, the fetus was found to have a right ventricular aneurysm or divertriculum protruding beneath the tricuspid valve annulus. All three continued to term and at no time demonstrated cardiovascular compromise
