description: Aim: We aim at measuring the chemical gradients of the elements Mg, Al, Si, and Fe along the Galactic radius to provide new constraints on the chemical evolution models of the Galaxy and Galaxy models such as the Besancon model. Methods: We analysed three different samples selected from three independent datasets: a sample of 19,962 dwarf stars selected from the RAVE database, a sample of 10,616 dwarf stars selected from the Geneva-Copenhagen Survey (GCS) dataset, and a mock sample (equivalent to the RAVE sample) created by using the GALAXIA code, which is based on the Besancon model. We measured the chemical gradients as functions of the guiding radius (Rg) at different distances from the Galactic plane reached by the stars along their orbit (Zmax). Results: The chemical gradients of the RAVE and GCS samples are negative and show consistent trends, although they are not equal: at Zmax<0.4 kpc and 4.5

description: To explore and describe medical students, postgraduate medical trainees, and medical specialists’ perceptions of creativity, the importance they attach to creativity in contemporary healthcare, and, by extension, how they feel creativity can be taught in medical education. The authors conducted seven semi-structured focus groups with medical students (n = 10), postgraduate medical trainees (n = 11) and medical specialists (n = 13). Participants had a trifurcated perception of creativity, which they described as a form of art that involves thinking and action processes. Facing complex patients in a rapidly changing healthcare landscape, doctors needed such a multifaceted perspective to be able to adapt and react to new and often complex situations that require creativity. Furthermore, participants identified conditions that were perceived to stimulate and inhibit creativity in healthcare and suggested several techniques to learn creativity. Participants perceived creativity as a form of art that involves thinking and action processes. Creativity is important to tackle the challenges of current and future workplaces, because it stimulates the search for original solutions which are needed in a rapidly changing healthcare landscape. Participants proposed different methods and techniques to promote creativity learning. However, we need further research to design and implement creativity in medical curricula.

description: Timely and accurate information about the onset of malaria epidemics is essential for effective control activities in epidemic-prone regions. Early warning methods that provide earlier alerts (usually by the use of weather variables) may permit control measures to interrupt transmission earlier in the epidemic, perhaps at the expense of some level of accuracy. Expected case numbers were modeled using a Poisson regression with lagged weather factors in a 4th-degree polynomial distributed lag model. For each week, the numbers of malaria cases were predicted using coefficients obtained using all years except that for which the prediction was being made. The effectiveness of alerts generated by the prediction system was compared against that of alerts based on observed cases. The usefulness of the prediction system was evaluated in cold and hot districts. The system predicts the overall pattern of cases well, yet underestimates the height of the largest peaks. Relative to alerts triggered by observed cases, the alerts triggered by the predicted number of cases performed slightly worse, within 5% of the detection system. The prediction-based alerts were able to prevent 10–25% more cases at a given sensitivity in cold districts than in hot ones. The prediction of malaria cases using lagged weather performed well in identifying periods of increased malaria cases. Weather-derived predictions identified epidemics with reasonable accuracy and better timeliness than early detection systems; therefore, the prediction of malarial epidemics using weather is a plausible alternative to early detection systems.

description: For dust aggregates in protoplanetary discs a transition between sticking and bouncing in individual collisions at mm to cm size has been observed in the past. This lead to the notion of a bouncing barrier for which growth gets stalled. Here, we present long term laboratory experiments on the outcome of repeated aggregate collisions at the bouncing barrier. About 100 SiO$_2$ dust aggregates of 1 mm in size were observed interacting with each other. Collisions occured within a velocity range from below mm/s up to cm/s. Aggregates continuously interacted with each other over a period of 900 s. During this time more than $10^5$ collisions occured. Nearly 2000 collisions were analyzed in detail. No temporal stable net growth of larger aggregates was observed even though sticking collision occur. Larger ensembles of aggregates sticking together are formed but were disassembled again during the further collisional evolution. The concept of a bouncing barrier supports the formation of planetesimals by seeded collisional growth as well as by gravitational instability favouring a significant total mass being limited to certain size ranges. Within our parameter set the experiments confirm that bouncing barriers are one possible and likely evolutionary limit of a self consistent particle growth.

description: We present a new numerical Monte Carlo approach to determine the scaling behavior of lattice field theories far from equilibrium. The presented methods are generally applicable to systems where classical-statistical fluctuations dominate the dynamics. As an example, these methods are applied to the random-force-driven one-dimensional Burgers' equation - a model for hydrodynamic turbulence. For a self-similar forcing acting on all scales the system is driven to a nonequilibrium steady state characterized by a Kolmogorov energy spectrum. We extract correlation functions of single- and multi-point quantities and determine their scaling spectrum displaying anomalous scaling for high-order moments. Varying the external forcing we are able to tune the system continuously from equilibrium, where the fluctuations are short-range correlated, to the case where the system is strongly driven in the infrared. In the latter case the nonequilibrium scaling of small-scale fluctuations are shown to be universal.

description: To survey the current educational trends and methods of ophthalmology teaching in Australian undergraduate and postgraduate medical schools. Cross-sectional survey; National online survey distributed to Australian university undergraduate and post-graduate medical schools from November 2020 to March 2021. The survey encompassed 35 questions on student demographics, teaching methods, core theoretical topics, clinical skills, and assessment methods in ophthalmology. One survey per institution completed by the relevant individual responsible for curriculum. Total response rate of 90.48% (19 of 21 medical schools) was received with good representation across Australia. Ophthalmology rotations were required in 63.3% (n = 12), while 36.7% (n = 7) did not have mandatory terms. This compares favourably to the USA (16%), Canada (35.7%) and equivalent to UK (65%). 74% (n = 14) state ophthalmology is not a priority in the curriculum. All respondents reported student exposure to at least one clinical day in ophthalmology, with total teaching time ranging from less than six hours (36.9%), up to greater than two weeks (10.5%). Overall, only 31.6% reported utilisation of the International Council of Ophthalmology (ICO) curriculum in curricular development. Ophthalmology medical school teaching in Australia remains reasonable when compared internationally, but there is significant variation amongst universities. Incorporation of the ICO curriculum and development of shared resources would enhance medical graduates’ competence.

description: Palliative care is constantly increasing around the world. The knowledge and skills of future physicians in this area are crucial. This study evaluates the psychometric properties of knowledge and skills questionnaires used in palliative care, validated by physicians or medical students based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. A systematic review was carried out in Cosmin Databases, Cochrane Library, PsycINFO, SciELO, Cinahl, and Medline up to September 2020 (updated June 2021), based on the COSMIN methodology and PRISMA recommendations. The psychometric properties of each included questionnaire were identified. Methodological quality, quality of results, and quality of evidence were evaluated. The search strategy yielded 12 questionnaires assessing the knowledge and skills of physicians or medical students. The Palliative Care Knowledge Questionnaire for PEACE (PEACE-Q) and Palliative Care Knowledge Test (PCKT) were the instruments with the highest scores for methodological quality, quality of results, and quality of evidence-based on the COSMIN methodology. PEACE-Q and PCKT should be the preferred choice to assess palliative care knowledge and skills in physicians. In-depth studies following COSMIN validation criteria are recommended to improve the psychometric properties and cross-cultural validation of the questionnaires.

description: Stable vortex dimers are known to exist in coherently coupled two component Bose-Einstein condensates (BECs). We construct stable vortex trimers in three component BECs and find that the shape can be controlled by changing the internal coherent (Rabi) couplings. Stable vortex N-omers are also constructed in coherently coupled N-component BECs. We classify all possible N-omers in terms of the mathematical graph theory. Next, we study effects of the Rabi coupling in vortex lattices in two-component BECs. We find how the vortex lattices without the Rabi coupling known before are connected to the Abrikosov lattice of integer vortices with increasing the Rabi coupling. In this process, vortex dimers change their partners in various ways at large couplings. We then find that the Abrikosov lattices are robust in three-component BECs.

description: In quantitative mass spectrometry-based proteomics, the metabolic incorporation of a single source of ¹⁵N-labeled nitrogen has many advantages over using stable isotope-labeled amino acids. However, the lack of a robust computational framework for analyzing the resulting spectra has impeded wide use of this approach. We have addressed this challenge by introducing a new computational methodology for analyzing ¹⁵N spectra in which quantification is integrated with identification. Application of this method to an Escherichia coli growth transition reveals significant improvement in quantification accuracy over previous methods.

description: Quality improvement (QI) projects are a mandatory part of postgraduate medical training in the UK and graduating medical students must be competent in QI theory. We evaluated an educational toolkit that links concepts of sustainable healthcare with established quality improvement methodologies (the SusQI approach, available at www.susqi.org). The SusQI approach was implemented across a range of undergraduate and postgraduate nursing and medical education contexts. Educational strategies included guided online learning, live interactive webinars, small group activities and scaffolded project work. The evaluation strategy was informed by theories of academic motivation, educational value within communities of practice and behaviour change. A simultaneous nested design was tested using a mixed methods survey with input from learners and teachers. 177 survey responses were analysed to quantify and compare self-rated impacts of teaching across different audiences. Qualitative data were inductively coded into themes that were categorised according to above theoretical frameworks. Participants felt that this was ‘time well spent’ and many described transformative impacts that guided their daily professional practice beyond learning about QI. We suggest that meaningful space is found within both undergraduate and postgraduate healthcare curricula for SusQI, as a way of engaging and motivating learners to contribute to the creation of a sustainable healthcare system.
Multivariate time-space harmonic polynomials: a symbolic approach

Subjects: subject: Probability (math.PR)

description: By means of a symbolic method, in this paper we introduce a new family of multivariate polynomials such that multivariate Lévy processes can be dealt with as they were martingales. In the univariate case, this family of polynomials is known as time-space harmonic polynomials. Then, simple closed-form expressions of some multivariate classical families of polynomials are given. The main advantage of this symbolic representation is the plainness of the setting which reduces to few fundamental statements but also of its implementation in any symbolic software. The role played by cumulants is emphasized within the generalized Hermite polynomials. The new class of multivariate Lévy-Sheffer systems is introduced.

Understanding The Global Sources And Sinks Of Atmospheric Carbonyl Sulfide In Order To Provide Insights Into Carbon Cycle Processes
Creators: name: Cartwright, Michael P.
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: This thesis focuses on the modelling and measurement of atmospheric OCS. Carbonyl sulfide (OCS) has emerged as a proxy for photosynthetic uptake of carbon dioxide (CO2) by plants. Multiple mechanistic and scaling approaches for inferring CO2 uptake, known as gross primary productivity (GPP), are emerging and the need for a global satellite dataset of OCS is crucial. The atmospheric three-dimensional chemical transport model TOMCAT is used to model global atmospheric OCS. A leaf relative uptake (LRU) approach is applied to GPP fields in order to infer OCS vegetative uptake, estimated to be approximately 629 Gg S yr-1, which is at the lower end of estimates from previous studies (238 – 1335 Gg S yr-1). The remaining fluxes are extracted from the literature and scaled accordingly in order to close the OCS budget. A comparison is made with National Oceanographic and Atmospheric Administration - Earth System Research Laboratories (NOAA-ESRL) surface flask observations and the mean error reduction across all sites is approximately 25%, compared to a control simulation. TOMCAT is compared to profiles of OCS from the limb-sounding satellite instrument Atmospheric Chemistry Experiment – Fourier Transform Spectrometer (ACE-FTS), which show an excellent comparison throughout most of the atmosphere to within ±25 ppt, approximately 5% in the troposphere. The University of Leicester IASI Retrieval Scheme (ULIRS) is adapted to retrieve profiles of OCS globally from atmospheric spectra recorded by the Infrared Atmospheric Sounding Interferometer (IASI), primarily over the oceans, OCSOCE. A spectrally resolved emissivity product is implemented in a first effort to improve land-based retrievals of OCS, OCSTER. Total column random errors are found to range between 18 and 38%. A comparison is made between OCSOCE and TOMCAT, agreeing to within ±5% throughout most of the tropics (30°S – 30°N). The seasonality of OCSOCE is compared to surface observations, showinga correlation coefficient of 0.92 with measurements at Mauna Loa, Hawaii. Agreement of OCSTER with TOMCAT to within ±5% is limited to 20°S – 20°N. Finally, a flux inversion is performed by assimilating surface flask observations of OCS for 16 regions and 5 flux sectors, INVOCS. Mean INVOCS error reduction is 23% across all regions and the root mean square error is reduced by an average of 51% compared to the a priori mixing ratios. INVOCS shows a substantial shift in vegetative uptake from the tropics to the northern hemisphere extra tropics and the opposite for oceanic emissions. An independent comparison with ACE-FTS shows agreement within ±30 ppt throughout most of the troposphere, with a predominantly negative bias in the a priori mixing ratios, but positive bias in the a posteriori.
Economic Exchange During Hyperinflation

Publisher: name: Columbia University
Year: 1990
Subjects: Economics

description: Historical evidence indicates that hyperinflations can disrupt individuals'
normal trading patterns and impede the orderly functioning
of markets. To explore these issues, we construct a theoretical model
of hyperinflation that focuses on individuals and their process of
economic exchange. In our model buyers must carry cash while
shopping, and some transactions take place in a decentralized setting
in which buyer and seller negotiate over the terms of trade of an
indivisible good. Since buyers face the constant threat of incoming
younger (hence richer) customers, their bargaining position is weakened
by inflation, allowing sellers to extract a higher real price. However,
we show that higher inflation also reduces buyers' search,
increasing sellers' wait for customers. As a result, the volume
of transactions concluded in the decentralized sector falls. At high
enough rates of inflation, all agents suffer a welfare loss.

description: Faculty are motivated to pursue clinician-educator careers out of a sense of purpose, duty, connectedness, satisfaction, and mastery. Yet, many suffer from burnout due to a lack of funding, resources, and competing clinical demands. Reasons for clinician-educator participation in unfunded educational leadership positions are underexplored. This study examined faculty members’ reasons for volunteering and remaining as clerkship elective directors, an unfunded leadership position. In this qualitative study, the authors conducted 17 semi-structured interviews with clerkship elective directors in March 2021. The authors conducted a thematic analysis of deidentified transcripts using motivation theories as a lens. Directors’ motivations to engage in this unfunded educational leadership position stemmed from their existing clinician-educator identity and a sense of purpose and duty. Directors are sustained by the satisfaction derived from witnessing the positive impact they have on learners’ career development and skills building, the impact of learners on the clinical environment, as well as personal benefits in the mastery of educator skills and enhanced visibility as educators. Unfunded educational leadership positions can advance clinician-educators’ commitment to learners and alter the learning environment. Strategies for faculty recruitment and retention in unfunded leadership positions include ensuring meaningful contact with learners, as well as opportunities for personal career development through skills building and enhanced visibility through recognition.

description: The integration of remote sensing data with socioeconomic data presents new opportunities for scientific discovery and analysis that can improve understanding of the environmental sustainability issues that society faces today. Such integrated data products and services can be used to study interdisciplinary issues by investigators representing various disciplines. In addition to the scientific benefits that can be attained by integrating remote sensing data with socioeconomic data, the integration of these data also present challenges that reflect the complex issues that arise when sharing and integrating different types of science data. When integrating one or more datasets that contain sensitive information, data producers need to be aware of the limitations that have been placed upon the data to protect private property, species or other inhabitants that reside on the property, or restricted information about a particular location. Similarly, confidentiality and privacy issues are a concern for data that have been collected about individual humans and families who have volunteered to serve as human research subjects or whose personal information may have been collected without their knowledge. In addition, intellectual property rights that are associated with a particular dataset may prevent integration with other data or pose constraints on the use of the resulting data products or services. These challenges will be described along with approaches that can be applied to address them when planning projects that involve the integration of remote sensing data with socioeconomic data.

description: The biological mechanisms responsible for the onset and exacerbation of asthma symptoms in children may involve the epigenetic regulation of inflammatory genes after environmental exposures. Using buccal cells, we hypothesized that DNA methylation in promoter regions of two asthma genes, inducible nitric oxide synthase (iNOS) and interferon γ (IFNγ), can vary over several days. Repeat buccal samples were collected 4 to 7 days apart from 34 children participating in the Columbia Center for Children's Environmental Health (CCCEH) birth cohort study. Several field duplicates (sequential collection of two samples in the field) and replicates (one sample pyrosequenced twice) also were collected to ensure consistency with collection and laboratory procedures. DNA methylation was assessed by pyrosequencing a PCR of bisulfite-treated DNA. We found that replicate and field duplicate samples were correlated strongly (r = 0.86 to 0.99, P < 0.05), while repeat samples demonstrated low within-subject correlations (r = 0.19 to 0.56, P = 0.06 to 0.30). Our data reveal DNA methylation as a dynamic epigenetic mechanism that can be accessed safely and reproducibly in an inner city pediatric cohort using non-invasive buccal swabs and pyrosequencing technology.

description: Climate change has increased the days of unseasonal temperature. Although many studies have examined the association between temperature and mortality, few have examined the timing of exposure where whether this association varies depending on the exposure month even at the same temperature. Therefore, we investigated monthly differences in the effects of temperature on mortality in a study comprising a wide range of weather and years, and we also investigated heterogeneity among regions. We analyzed 38,005,616 deaths from 148 cities in the U.S. from 1973 through 2006. We fit city specific Poisson regressions to examine the effect of temperature on mortality separately for each month of the year, using penalized splines. We used cluster analysis to group cities with similar weather patterns, and combined results across cities within clusters using meta-smoothing. There was substantial variation in the effects of the same temperature by month. Heat effects were larger in the spring and early summer and cold effects were larger in late fall. In addition, heat effects were larger in clusters where high temperatures were less common, and vice versa for cold effects. The effects of a given temperature on mortality vary spatially and temporally based on how unusual it is for that time and location. This suggests changes in variability of temperature may be more important for health as climate changes than changes of mean temperature. More emphasis should be placed on warnings targeted to early heat/cold temperature for the season or month rather than focusing only on the extremes.

All respondents reported student exposure to at least one clinical day in ophthalmology, with total teaching time ranging from less than six hours (36.9%), up to greater than two weeks (10.5%). Overall, only 31.6% reported utilisation of the International Council of Ophthalmology (ICO) curriculum in curricular development. Ophthalmology medical school teaching in Australia remains reasonable when compared internationally, but there is significant variation amongst universities. Incorporation of the ICO curriculum and development of shared resources would enhance medical graduates’ competence.

description: Children with disabilities are more likely to have sleep disturbances than children without disabilities. Identifying attitudes, beliefs, knowledge, and perceptions of caregivers and health professionals is essential in developing effective intervention programs to improve disabled children’s sleep health. However, no such qualitative data about adults who have key roles in the life and daytime activities of children with disabilities are available. This qualitative study aimed to understand attitudes, beliefs, knowledge, and perceptions about disabled children’s sleep hygiene among caregivers and rehabilitation providers of children with disabilities. Twenty seven adults, including nine primary caregivers and eighteen rehabilitation providers, participated in five focus group discussions between September and December 2012 at the Rehabilitation Center in Punta Arenas, Chile. A trained facilitator guided focus group discussions using a semi-structured script. Audiotapes and transcripts of focus group discussions were reviewed and analyzed for recurrent themes. Participants identified seven themes related to children’s sleep hygiene: lifestyle behaviors, family factors, children’s disabilities and/or comorbidities, environmental factors, adults’ responsibilities for children’s sleep, perception of good sleep, and parental distress about children’s sleep problems. While both caregivers and rehabilitation providers recognized the importance of sleep for children’s health and functioning, they differed in their understanding of how sleep hygiene practices influence sleep. Rehabilitation providers recognized the negative influence of electronics on sleep and the positive influence of sleep routines. In contrast, caregivers reported use of television/movie watching and stimulants as coping strategies for managing children’s sleep problems. Caregivers may benefit from better understanding the influence of electronics and stimulant use on child sleep health. Rehabilitation providers are well positioned to provide educational messages to both children and caregivers in order to change their attitudes, perceptions, and practices surrounding sleep. These qualitative data are valuable in developing intervention programs aimed at improving sleep health among children with disabilities.

description: To explore and describe medical students, postgraduate medical trainees, and medical specialists’ perceptions of creativity, the importance they attach to creativity in contemporary healthcare, and, by extension, how they feel creativity can be taught in medical education. The authors conducted seven semi-structured focus groups with medical students (n = 10), postgraduate medical trainees (n = 11) and medical specialists (n = 13). Participants had a trifurcated perception of creativity, which they described as a form of art that involves thinking and action processes. Facing complex patients in a rapidly changing healthcare landscape, doctors needed such a multifaceted perspective to be able to adapt and react to new and often complex situations that require creativity. Furthermore, participants identified conditions that were perceived to stimulate and inhibit creativity in healthcare and suggested several techniques to learn creativity. Participants perceived creativity as a form of art that involves thinking and action processes. Creativity is important to tackle the challenges of current and future workplaces, because it stimulates the search for original solutions which are needed in a rapidly changing healthcare landscape. Participants proposed different methods and techniques to promote creativity learning. However, we need further research to design and implement creativity in medical curricula.
Expanded methods to model last year of life expenditures in the medicare current beneficiary survey with sensitivity analyses and new findings

description: Terminal year of life medical expenditures in the elderly are generally much higher than medical expenditures in other years of life. These expenditures have often been portrayed as wasteful and inefficient use of heroic procedures with little change of success at the end of life. Prior studies in this area have focused predominately on Medicare expenditures; only a handful considered overall medical expenditures. The Medicare Current Beneficiary Survey (MCBS) comprises data on all medical expenditures, not just those paid for by Medicare, but these data only include expenditures aggregated by calendar year. Thus, linear models have been applied to estimate terminal year of life medical expenditures.This paper adds to the body of information on this topic using recent data, from the 2006-2013 MCBS. We modified previous and developed new methods to estimate end-of-life expenditures both overall and broken down by payer and service category. We also developed new sensitivity analyses to test data and model assumptions. Additionally, we compared variances of the estimates from two predominate methods for robust variance estimation in complex surveys like the MCBS, the Taylor Series Expansion (TSE) method and Fay’s modification to the Balanced Repeated Replication (BRR) method. Finally, we utilize our new method of analysis to examine univariate and multivariate covariate effects of calendar year, age, sex, race, and geographical region on selected categories of terminal year of life expenditures. This is to our knowledge, the first multivariate analysis of multivariate correlates for total end-of-life medical expenditures.

description: We have performed a low temperature scanning tunneling microscopy and spectroscopy study of the iron chalcogenide superconductor FeSe_{0.4}Te_{0.6} with T_{C}~14 K. Spatially resolved measurements of the superconducting gap reveal substantial inhomogeneity on a nanometer length scale. Analysis of the structure of the gap seen in tunneling spectra by comparison with calculated spectra for different superconducting order parameters (s-wave, d-wave, and anisotropic s-wave) yields the best agreement for an order parameter with anisotropic s-wave symmetry with an anisotropy of ~40%. The temperature dependence of the superconducting gap observed in places with large and small gap size indicates that it is indeed the superconducting transition temperature which is inhomogeneous. The temperature dependence of the gap size is substantially larger than would be expected from BCS theory. An analysis of the local gap size in relation with the local chemical composition shows almost no correlation with the local concentration of Se-/Te-atoms at the surface.

description: The renormalization of N=1 Super Yang-Mills theory is analysed in the Wess-Zumino gauge, employing the Landau condition. An all orders proof of the renormalizability of the theory is given by means of the Algebraic Renormalization procedure. Only three renormalization constants are needed, which can be identified with the coupling constant, gauge field and gluino renormalization. The non-renormalization theorem of the gluon-ghost-antighost vertex in the Landau gauge is shown to remain valid in N=1 Super Yang-Mills. Moreover, due to the non-linear realization of the supersymmetry in the Wess-Zumino gauge, the renormalization factor of the gauge field turns out to be different from that of the gluino. These features are explicitly checked through a three loop calculation.

description: Magnetic properties of DNA liquid-crystal dispersions are experimentally investigated by SQUID magnetometer. The magnetic susceptibility of pure DNA and DNA doped by La, and Gd is measured in the region 4.2-300 K. The total magnetic moment is represented as a sum of: the paramagnetic part and negative diamagnetic part. The number of paramagnetic Gd3+ ions is calculated in a good agreement with the number of phosphate complexes. The temperature dependence of magnetic susceptibility indicates the presence of interaction between Gd3+ magnetic moments, which is discussed in terms of long-range RKKY-type exchange in one-dimensional metals.

description: The analysis of the contributions to synaptic plasticity and memory of cAMP, PKA, CRE, CREB-1, CREB-2, and CPEB has recruited the efforts of many laboratories all over the world. These are six key steps in the molecular biological delineation of short-term memory and its conversion to long-term memory for both implicit (procedural) and explicit (declarative) memory. I here first trace the background for the clinical and behavioral studies of implicit memory that made a molecular biology of memory storage possible, and then detail the discovery and early history of these six molecular steps and their roles in explicit memory.
