title: The DReAM framework: a logic-inspired approach to reconfigurable system modeling
Creators: name: Maggi, Alessandro
Publisher: name: IMT Alti Studi Lucca
Year: 2020

description: Modern systems evolve in unpredictable environments and
have to continuously adapt their behavior to changing conditions.
The DReAM (Dynamic Reconfigurable Architecture
Modeling) framework has been designed to address these requirements
by offering the tools for modeling reconfigurable
dynamic systems effectively.
At its core, the framework allows component-based architecture
design leveraging a rule-based language, inspired from
Interaction Logic. The expressiveness of the language allows
us to define the behavior of both components and components
aggregates encompassing all aspects of dynamicity, including
parametric multi-modal coordination of components and reconfiguration
of their structure and population.
DReAM allows the description of both endogenous/modular
and exogenous/centralized coordination styles and sound
transformations from one style to the other, while adopting a
familiar and intuitive syntax. To better model dynamic mobile
systems, the framework is further extended with two structuring
concepts: motifs - independent dynamic architectures
coordinating components assigned to them - and maps - graphlike
data structures modeling the topology of the environment
and parametrizing coordination between components.
The jDReAM Java project has been developed to provide an
execution engine with an associated library of classes and
methods that support system specifications conforming to the
DReAM syntax. It allows to develop runnable systems combining
the expressiveness of the rule-based notation with the
flexibility of this widespread programming language.

description: Many chemical reactions generate different products or show different reactivities depending on the solvent in which the reaction runs. Despite the empirical understanding of these effects, their basis in theory is only partially developed. In this investigation, we studied the SN2 reaction CH3Cl + NH3 in acetonitrile or aqueous solution. All molecules were treated at the B3LYP/6-31G+ level of theory using GAMESS and NWChem. We discuss the relative importance of solvent effects on the thermodynamics versus the kinetics of the reaction

Computational Strategies to Reactivate Glucose Uptake through Increased GLP-1 Lifetime

Year: 2022

description: In type 2 diabetes, high blood sugar leads to hyperinsulinemia, which, over time, causes the body to develop insulin resistance and hyperglycemia. The short-lived peptidic hormone glucagon-like peptide 1 (GLP-1) signals for insulin release. Dipeptidyl peptidase 4 (DPP-4) regulates circulating GLP-1 lifetime through cleavage of the first two N-terminal amino acids. Inhibition of this cleavage clinically leads to reversal of diabetic symptoms but blocks the regulatory function DPP-4 has on other circulating hormone peptides. Selective prolonging of GLP-1 signaling is therefore a desirable area of current research. We probed three different approaches to formulate a drug that solves these problems. Our first approach used ChimeraX to characterize the binding pockets and key interactions of different substances in DPP-4. Pharmacophores that would decrease the activity of the enzyme but not eliminate GLP-1 binding were identified. Our second approach involved aligning different DPP-4 substrates to a short peptide bound to DPP-4 in order to estimate where GLP-1 bound outside the active site. Our results suggest GLP-1 binding may involve sites distinct from many of the other DPP-4 substrates, offering a path towards selective inhibition. Our third approach looked for ways to enhance the binding of GLP-1 to its receptor in the absence of its N-terminal amino acids. Key pharmacophore sites were identified.

description: We present a numerical method for computing optimal transition pathways and transition rates in systems of stochastic differential equations (SDEs). In particular, we compute the most probable transition path of stochastic equations by minimizing the effective action in a corresponding deterministic Hamiltonian system. The numerical method presented here involves using an iterative scheme for solving a two-point boundary value problem for the Hamiltonian system. We validate our method by applying it to both continuous stochastic systems, such as nonlinear oscillators governed by the Duffing equation, and finite discrete systems, such as epidemic problems, which are governed by a set of master equations. Furthermore, we demonstrate that this method is capable of dealing with stochastic systems of delay differential equations.

Virtual Screening for Potential Selective Inhibitors of Macrophage Infectivity Potentiator Proteins

description: The bacterial Macrophage Infectivity Potentiators proteins (MIPs) appear to play a crucial role in bacterial penetration of epithelial linings and infection of macrophages. MIPs possess a binding domain analogous to human FK506 Binding Proteins (FKBP) that binds and weakens collagen membrane, allowing bacterial passage into tissues and away from the lysosomes of macrophages. Diverse strains of lethally infective bacteria, such as Legionella pneumophila (LP), Burkholderia pseudomallei and Coxiella burnetii, express MIPs or MIP-like proteins. We hypothesize that dosing MIP selective inhibitors could prevent bacterial infiltration of epithelial linings or macrophages while sparing human immune response. To identify prospective ligands, the key interactions of rapamycin bound to LP MIP were converted to pharmacophores and searched against all available chemicals in ZINCPharmer. After preparing the proteins and potential ligands in UCSF Chimera, ZINCPharmer hits were docked against the LP MIP and human FKBP12 using AutoDock 4. Multiple hits with affinity similar to rapamycin against LP MIP were identified, some of which are predicted to have lower affinities than rapamycin against FKBP12. These virtual screening hits represent potential starting points for potent, selective MIP inhibitors, providing possibly prophylactic measures or even treatments against drug resistant bacteria.

description: De Novo Design: Sugar BindingANNIE MCALLISTER, Kenneth Foreman, Department of Chemistry and Biochemistry, George Mason University.Although nature provides proteins that bind sugars, the exact forces that lead to specific binding or high affinity complexation are poorly understood. De novo design seeks to understand the fundamental chemistry of proteins and particularly what forces drives their intra- and inter- molecular interactions. We have applied de novo design approaches in a virtual setting to model the binding of glucose, ribofuranose, and phosphoribose to a four-helix bundle originally intended to bind heme. Three binding sites were created by modifying the protein sidechains in Chimera to create opportunities for hydrogen bond formation with the sugars. Two sites were made specifically to bind ribose while the third was intended to bind glucose. The sugars were docked and scored in AutoDock. All sites had specificity for one sugar over the others. However, the phosphoribose featured stronger predicted binding in the site designed for ribose than the ribofuranose itself. These results suggest a combination of sterics and well-placed electrostatic interactions drive specificity in protein-sugar interactions.

title:  Experiences in Physical Education and Sport: The Intersection of Identifying as a Female, an Athlete, and Visually Impaired
Creators: name: Buckley, Margaret
Publisher: name: Old Dominion University Libraries
Year: 2020

description: Introduction. Individuals with visual impairments, females, and athletes encounter different challenges during physical education. However, little is known about how the challenges connected with each of these identities intersect and if that intersection impacts experiences differently. The purpose of this study was to take an explicitly intersectional approach to understand how identifying as an individual with a visual impairment, a female, and an athlete intersect to influence physical education and sport experiences. Methods. To describe the participants’ intersectional experiences as female athletes with a visual impairment, an interpretative phenomenological analysis (IPA) research approach was implemented. Four female athletes with visual impairments aged 23-28-years old, participated in this study. The study utilized two sources of data: semi-structured, audio-taped, telephone/video call interviews and reflective interview notes. Data were analyzed thematically using a three-step process guided by IPA. Results. From the data collected and analyzed, two connected, major themes were constructed (a) Physical education was ‘just a credit’ and (b) ‘If you enjoy this, we will drive you’. Discussion. The results of this study aligned with prior research (Fitzgerald, 2005; Haegele & Zhu, 2017), by demonstrating the participants did not have meaningful physical education experiences. Interestingly, however, the participants noted that these poor experiences were not critical to them, as they had developed a sense of athletic identity in other, outside of school physical activity opportunities supported by family.

description: Genus Fotolaimus Belogurova & Belogurov, 1974
Type species.
 Fotolaimus marinus Belogurova & Belogurov, 1974.
Diagnosis
 (modified from Belogurova and Belogurov 1974). Oncholaiminae. Left ventrosublateral tooth larger than the two other teeth. Spicules shorter than 2.0 cloacal body diameters. Gubernaculum present. Demanian system present, posterior end of main duct forming two symmetrical sacs each with five or more terminal ducts.
Remarks.
 The genus Fotolaimus can be distinguished from Metaparoncholaimus and Wiesoncholaimus by the left ventrosublateral tooth being larger than the right ventrosublateral tooth (left and right ventrosublateral teeth are equal in size in Metaparoncholaimus and Wiesoncholaimus). It also differs from Prooncholaimus by the absence of the large bubble-like cells in pseudocoelom (presence in Prooncholaimus). Fotolaimus, Oncholaimus, and Metoncholaimus are similar to each other and are distinguished by the morphological characters of the terminal ducts of the Demanian system. Belogurova and Belogurov (1974) characterized the Demanian system of Fotolaimus as follows: the posterior end of the main duct forms two symmetrical sacs, each of which is pierced by five terminal ducts ending in terminal pores. On the other hand, the main ducts of Oncholaimus and Metoncholaimus do not form a sac at the posterior end, but branch separately into two or more terminal ducts (Belogurov and Belogurova 1988). Belogurov and Belogurova (1977) distinguished Metoncholaimus from Oncholaimus in that the terminal ducts are covered with moniliform glands. However, some Metoncholaimus species do not mention the shape of the terminal duct in their description (e.g., Mawson 1958; Salma et al. 2017). For convenience, a species may be considered belonging to Oncholaimus if it has short (equal to cloacal body diameter) spicules and without gubernaculum, and belonging to Metoncholaimus if it has longer spicules (with or without gubernaculum) or short spicules with gubernaculum (cf. Platt and Warwick 1983). The distinction between Oncholaimus and Metoncholaimus will need to be reexamined in the future.

Neutrino fluxes have been obtained using ATMNC, a simulation code for cosmic ray in the atmosphere. Even using the same primary flux model and the interaction model, the calculated atmospheric neutrino fluxes are different for the different sites due to the geomagnetic field. The prediction of these fluxes in the present paper would be quite useful in the experimental analysis.

Computational Exploration of Remote Directing Groups and Their Effects on Creating Grignard Reagents

Publisher: name: Journal of Student-Scientists' Research
Year: 2022

description: The commonly employed Grignard reaction involves carbon-carbon bond formation between a Grignard reagent, a magnesium halide bound to a carbon, and an electron-accepting substrate. Formation of alkyl Grignard reagents is often difficult and hence expensive for late stage intermediates. Creating inexpensive exchange agents that can place a magnesium halide on those intermediates while accepting a halide from the intermediate are highly desirable. Electron-rich groups potentially facilitate this exchange by directing the magnesium to the exchange position and stabilizing it. We explored aryl groups tethered by alkyl chains of varying lengths as remote directing groups. Using the B3LYP/CC-PVTZ level of theory in GAMESS on the Hopper Cluster, the exchange energies for various designs were calculated. Tether length mattered for the directing group, with shorter chains favored. Several aromatics yielded favorable exchange capacities. While these results are encouraging, a more complete exploration of the dependence of exchange capacity on tether length and electronic effects in the aromatic system are still required.

title: POETIC TEXT AND ITS ICONOGRAPHIC INTERPRETATION: THE AKATHISTOS HYMN IN THE RUSSIAN AND CRETAN RELIGIOUS ART

description: This paper focuses on topics relevant to the visual interpretation of poetic verbal texts in their source culture as well as the target culture for which they were translated. The research was realized on fresco and icon cycles that illustrate the poetic text of the Akathistos Hymn. The Greek original text of the hymn is examined in contrast to its Slavonic translation through a parallel comparative analysis of their iconographic interpretations in Russian and Cretan religious art. Seeing as they have never been comparatively studied before, this analysis provides fertile ground for interesting discoveries and research. The Cretan tradition is studied through two complete Akathistos fresco cycles (from the church in the village of Roustica and the cathedral of Valsamonero Monastery), four incomplete Akathistos fresco cycles from the 14th – early 15th century, and the margin scenes on the icon of Panagia Galactotrofousa (1748) by G. Kastrofilakas. The Russian tradition is studied through a fresco cycle from the Ferapontov monastery (approx. 1500) by Dionisius, and the margin scenes on six Russian icons representing different iconographic schools of the 16th – early 17th century. The differences between these two iconographic traditions in regard to the text’s interpretation are divided into two categories: a) those related to the differences between the original text and its Slavonic translation; and b) those related to the different connotations of the original text and its Slavonic translation in the source and target cultures. Typical examples of both categories are presented.

description: The amplitude of the diphoton decay of the Higgs boson is considered in an extension of the Standard Model involving heavy vectorlike fermions, which was recently suggested in the literature in order to explain a possible enhancement of the h -> gamma gamma decay rate. It is pointed out that generally in such models the decay amplitude acquires a sizable CP-odd contribution from the complex phases in the mass matrix of the new heavy fermions. The resulting CP violation in the diphoton decay can be studied experimentally when both photons are converted into e^+ e^- pairs by measuring the distribution over the angle between the planes of the pairs. Such measurement, if feasible, would be of a great interest on its own, regardless specific models.

description: Human volatile organic compounds (hVOCs) are gaseous compounds at room temperature and make up the scent of an individual. Recently, there has been great interest in using hVOCs for diagnosing disease in individuals as well as for forensics purposes. The purpose of this research project is to assess a new device for capturing hVOCs (a â€œHotPodâ€) and to determine the effect of temperature on hVOC analysis. To capture the hVOCs, either of two test subjects stood inside the HotPod (an enclosed metal chamber with a heater, humidifier, thermostat, and vacuum) for a set incubation time, with the temperature set to either 20 Â°C or 40 Â°C. We also placed an internal standard (IS-1) within the HotPod to ensure the HotPod was functioning consistently. After the incubation period, we turned the HotPod vacuum on to transfer the captured VOCs into a sealed bag, injected another internal standard (IS-2) into the bag, then analyzed the sample by Thermal Desorption Gas Chromatography Mass Spectrometry (TD-GC-MS). The results compare the effect of temperature on the derived hVOC profile.

description: The Effect of Heat on Human Volatile Organic Compound Analysis.Human volatile organic compounds (hVOCs) are organic gases with high vapor pressure that are emitted through a human's breath or sweat. Recent investigations have shown that hVOCs can be used to diagnose diseases and distinguish between individuals. This study aimed to examine the effect of temperature on the production and differentiation of hVOCs emitted by human skin, and to test a new method for capturing the VOCs. In order to collect the hVOC samples, we used a custom made â€˜HotPod', which resembles an old-fashioned telephone booth, but is designed to control temperature, relative humidity, and permit the collection of hVOCs. To perform this investigation, two test subjects (â€˜Participant 1' and â€˜Participant 2') stood in a HotPod for a specific time period, with the HotPod set to either 20 oC or 40 oC. To ensure the HotPod was functioning consistently, an internal standard (IS-1) was placed in the HotPod along with the study Participant. After the specified time period, the HotPod vacuum was activated to capture the emitted hVOCs into a sealed bag. A second internal standard (IS-2) was added to the bag then the contents examined by Gas Chromatography-Mass Spectrometry (GC-MS) coupled with Thermal Desorption (TD).

description: Die Frage, inwieweit es möglich und sinnvoll ist, Kinder im Elementar- und Primarbereich an naturwissenschaftlichesDenken heranzuführen, wird gegenwärtig unterschiedlich beantwortet. Die Antwort hängt davon ab, wieeinerseits naturwissenschaftliches Denken gefasst wird und wie andererseits die heterogenen empirischen Befundezum Denken von Kindern im jeweiligen Alter interpretiert werden. Grundidee dieses Beitrags ist, dass ein derPraxis neuzeitlicher Naturwissenschaft angemessenes Verständnis naturwissenschaftlichen Denkens nur unter Rekursauf die Wissenschaftsforschung, also auf die Resultate der Wissenschaftsphilosophie (Hacking, 1996 [1983]),-geschichte (Gooding, 1990; Hentschel, 1998; Rheinberger, 2006; Steinle, 2005) und -soziologie (Latour, 2002),gewonnen werden kann. Meine These lautet, dass in vielen gegenwärtigen Versuchen, naturwissenschaftlichesDenken für die Zwecke der Elementarpädagogik und der Sachunterrichtsdidaktik zu fassen, naturwissenschaftlichesDenken in einer Weise gefasst wird, die vor dem Hintergrund der Ergebnisse der jüngeren Wissenschaftsforschungals inadäquat zu bewerten ist. Entsprechend können aus meiner Sicht auch weder die bejahenden noch dieverneinenden Antworten auf die Frage, ob Kinder im Elementar- und Primarbereich naturwissenschaftliche Denkenkönnen, überzeugen, sofern sie auf ein solches inadäquates Verständnis rekurrieren.

description: Recent discoveries of shifting baselines, which are changes in community composition over time, and declines of species diversity in wilderness areas such as the Congo, Amazon and North American deserts indicate changing diversity in undisturbed ecosystems. However, connections to how these changes impact ecological integrity are still unestablished. Here we assess the impact of shifting baselines on the functional diversity of bird communities in continuous Amazonian rainforest. We use understory bird diversity data from the Biological Dynamics of Forest Fragments Project near Manaus, Brazil to assess changes in functional diversity in primary forest over time. We use 40 years of mist-netted bird data in which birds were captured and their morphological traits were measured. We performed a principal component analysis to assess functional diversity in historic primary, modern primary, and modern disturbed forests from the 1980s to the 2010s. Results indicate that historic primary forest bird communities were significantly more diverse than modern primary or modern disturbed forest communities. As expected, modern disturbed forest is the least functionally diverse, yet even modern primary forest has lost functional diversity when compared with historic primary forest. Our data may speak to a global trend in decreasing functional diversity.

Responses are realized as independent and identically distributed (i.i.d.) random variables with a probability density function (p.d.f.) f, referred to as the superpopulation model. The selection is informative in the sense that the sample responses, given that they were selected, are not i.i.d. f. In general, the informative selection mechanism may induce dependence among the selected observations. The impact of such dependence on the empirical cumulative distribution function (c.d.f.) is studied. An asymptotic framework and weak conditions on the informative selection mechanism are developed under which the (unweighted) empirical c.d.f. converges uniformly, in $L_2$ and almost surely, to a weighted version of the superpopulation c.d.f. This yields an analogue of the Glivenko-Cantelli theorem. A series of examples, motivated by real problems in surveys and other observational studies, shows that the conditions are verifiable for specified designs.

description: The Biological Dynamics of Forest Fragments Project (BDFFP) in the central Amazon rainforest has been studying the effects of fragmentation for over 40 years. Forest fragmentation negatively impacts biodiversity, but it is not known how it affects different life stages of animals, thus we assess the impact on the breeding activity and the recruitment of young birds, predicting that both will be negatively impacted. Before and after the forest was isolated, understory birds were caught in mist nets and identified to species level, age, and assessed for signs of breeding activity. Mist netting occurred in 1ha, 10ha, 100ha, fragments and secondary, and primary forest. There were 418 fewer birds actively breeding and 48 fewer young after fragment isolation compared to before isolation. Primary forests had almost 4 times as many breeding birds and young as secondary forest and 8 times as many as forest fragments..More specifically, insect eating birds were negatively impacted more than other species, which provides evidence for the global decline in these birds. For example, the insect eating birds' young declined by 61% and their breeding activity by 74%, where as frugivore and nectivore young increased and breeding activity was largely unchanged. We demonstrated, for the first time, breeding activity and the recruitment of young are a bottle neck for species growth in forest fragments, and in second growth forest.

Evaluating the Effects of Deep Convection Parameter Perturbations on Cloud Radiative and Physical Properties in the Tropical Warm Pool

description: The Pliocene Epoch was the last time in Earth's history that atmospheric CO2 levels exceeded the elevated levels seen today. With geography similar to the present day, the Pliocene serves as a potential analog for future warming. However, sea surface temperature (SST) reconstructions reveal less warming in the Tropical Warm Pool (TWP) than climate models predict for future warming. This discrepancy suggests that climate models could be missing a cloud radiative damping mechanism in the TWP. To explore this, we use the Single Column Atmosphere Model v6 to simulate the TWP and systematically perturb parameters in the Zhang-McFarlane deep convection scheme. We do so without temperature relaxation at control and +4 degrees C prescribed SSTs. We then test the significance (alpha = 0.05) of the ordinary least-squares regression coefficients with respect to cloud properties. We find that precipitation efficiency (c0_ocn) is not significant with respect to changes in most cloud variables. Increased reevaporation of precipitation (ke) correlates most strongly with greater specific humidity, and hence, greater net clearsky forcing. Net cloud forcing (CF) decreases as the entrainment parameter (dmpdz) becomes less negative due to substantially less negative shortwave CF. A longer deep convection timescale (tau) weakly correlates to a decrease in longwave CF and increased shortwave CF. These correlations and their physical explanations provide a foundation for research into a cloud radiative damping mechanism in climate models.

description: Über die Entwicklung eines inklusiven Schulsystems werden in der Gegenwart sehr kontroverse Debatten geführt.Verschiedene Disziplinen diskutieren diesen Begriff mit teils sehr unterschiedlichen theoretischen Bezugsrahmen.Der Beitrag analysiert die Verwendung und den Bedeutungsgehalt des Begriffs im pädagogischen und soziologischenbzw. systemtheoretischen Diskurs, stellt Zusammenhänge von Inklusion und dem Diversity-Begriff herausund wirft einen Blick auf zwei inklusive didaktische Handlungs- und Planungsmodelle für den Sachunterricht (vgl.Gebauer, Simon 2013; Kahlert, Heimlich 2012). Zentrales Ziel ist es, durch eine interdisziplinäre Betrachtungsweisevon Inklusion Möglichkeiten für ein ‚Mehr‘ an Inklusion in Schule und Unterrichtzu diskutieren. Dabei sollder Umgang mit Heterogenität in beiden didaktischen Planungsmodellen für den inklusiven Sachunterricht mithilfeder theoretischen Vorannahmen untersucht und in ihren Herausforderungen und Potenzialen differenziertdargestellt werden.

description: We study the influence of particle shape on growth processes at the edges of evaporating drops. Aqueous suspensions of colloidal particles evaporate on glass slides, and convective flows during evaporation carry particles from drop center to drop edge, where they accumulate. The resulting particle deposits grow inhomogeneously from the edge in two-dimensions, and the deposition front, or growth line, varies spatio-temporally. Measurements of the fluctuations of the deposition front during evaporation enable us to identify distinct growth processes that depend strongly on particle shape. Sphere deposition exhibits a classic Poisson like growth process; deposition of slightly anisotropic particles, however, belongs to the Kardar-Parisi-Zhang (KPZ) universality class, and deposition of highly anisotropic ellipsoids appears to belong to a third universality class, characterized by KPZ fluctuations in the presence of quenched disorder.

description: Background: Stress has repeatedly been shown to have detrimental effects on cognitive ability. This has specific implications within the medical field given findings that physicians with a biomedical epistemology face greater stress than their biopsychosocial counterparts in the face of uncertainty.

Objective: The current study examined how induced stress affected participants’ cognitive abilities when prompted with positive or stoic regard, as well as observing possible intersecting factors that could affect this relationship. It was hypothesized that participants receiving positive regard during the stressor would have less impaired cognitive ability compared to participants receiving stoic regard. Furthermore, it was expected that the stoic condition would display increased arousal.

Methods: Effects were measured using heart rate measurements, a mood pre-appraisal, and a timed backwards counting task as a measure of cognitive ability. Measurements were taken at three points during the study: at baseline, following the stressor, and post-debriefing. Stress was induced using the Trier Social Stress Test (TSST).

Preliminary Results: Effects of condition on cognitive ability were approaching significance (p = .09) based on gender. Males matched expectations by performing better when receiving positive feedback, but female participants performed better only when receiving stoic feedback. Female participants also reported significantly lower positive mood at baseline (p < .05). Participants in the stoic condition also matched expectations of approaching significance (p = .07) for increased arousal (increased heart rate) in response to the stressor when compared to the positive condition.

Conclusion: The effect of regard on cognitive ability was dependent on gender. It is possible that female participants performed worse in the positive feedback condition due to increased sensitivity to perceived insincere compliments of cognitive ability. This effect could be amplified by females’ reported lower positive mood. Much still needs to be studied about the intersectionality of factors related to stress and cognition.

description: Due of its polymorphism, Mn$_2$FeSbO$_6$ can be synthesized at high pressures and temperatures as a ferrimagnetic ilmenite or an antiferromagnetic perovskite. The structural phase transformation is discussed in detail, and magnetic structures are proposed for both phases. The high-pressure Mn$_2$FeSbO$_6$ polymorph is a rare example of $A_2 B'B"$O$_6$ perovskite with solely Mn cations on the $A$-site. Fe and Sb cations are ordered on the $B$-sites. Theoretical calculations for the perovskite phase suggest a complex magnetic structure, holding an electronic polarization.
