description: In the evolving landscape of global geopolitics, the 21st century has witnessed a remarkable reversal in maritime power dynamics. In order to revitalize the status of the U.S. Navy, the Naval Research Laboratory(NRL) has conducted research on the effects of atmospheric corrosion on C1010 steel. Our research continues as Phase II of the initial research of a December 2022 study on atmospheric corrosion conducted by the U.S. NRL in Washington D.C., and aims to assess and record correlations between different atmospheric elements which may potentially influence the force readiness and operational status of the U.S. fleet. A study by Sanders and Santucci (2022) determined how different factors affect the atmospheric corrosion of C1010 Steel. By angling different plates of steel and by changing wind speed, the study provided a variety of data regarding how these different independent variables affect the corrosion of C1010 Steel. By using data analytics approaches such as principal component analysis (PCA) our research determines different correlations between humidity, temperature, wind speed and other environmental factors using the data provided in the original research paper. We are collaborating with Sanders and Santucci (2022) from the Naval Research Laboratory in their Phase II study to answer questions posed in the original study such as how the length of the experiment affects the mass loss of C1010 Steel. Their Phase I study utilized a long-term experiment while Phase II will focus on multiple short-term experiments. In order to conduct data analysis and explore correlations between atmospheric factors and corrosion of C1010 steel, various computer programs were employed. Firstly, we utilized principle component analysis (PCA) using python for data dimension reduction. Utilizing GGPLOT in RStudio, we constructed 2 dimensional graphs and conducted statistical analysis which showed a clear correlation in various atmospheric factors which proved to have a significant impact on corrosion of C1010 steel. Additionally, utilizing Excel spreadsheets, Pearson correlation coefficient values were calculated, allowing for detailed insight into the correlation between different elements. The data and correlation between different dataset and points can provide important insight regarding the importance of different conditions in atmospheric corrosion inside a marine environment. This research and data helps aid scientists and researchers, allowing for an improved fleet of the future. References: Sanders, C.E.; Santucci, R.J.

description: The neuromodulator acetylcholine supports learning, memory, and attention by modulating neural activity in the hippocampal formation. The primary source of acetylcholine release in the hippocampal formation stems from cholinergic projection neurons in the medial septum. However, little is known about the relationship between the activity of cholinergic neurons in the medial septum and real-time behavior. To further investigate this subject, we used fiber photometry to monitor the activity of cholinergic neurons using a genetically encoded Calcium indicator (GECI) while observing mouse behavior during free exploration through video recordings. The video recordings were analyzed with deep learning algorithms, namely DeepEthogram and DeepLabCut, to categorize each video frame into predetermined behaviors and track the animal’s position and orientation. GECI fluorescent cells (cholinergic neurons) were found by observing immunohistochemistry images of the mouse brain tissue. We present preliminary data on correlations of cholinergic activity with mouse behavior and 3D reconstruction of animal pose. Studying the link between cholinergic activity and behavior can lead to a better understanding of the hippocampal formation, which will be crucial in treating neurodegenerative diseases such as Alzheimer’s disease.

description: Shared rides are often considered to be a promising travel alternative that could efficiently pool people together while offering a door-to-door service. Notwithstanding, even though demand distribution patterns are expected to greatly affect the potential for ride-pooling, their impact remains unknown. In this study we explore the shareability of various demand patterns. We devise a set of experiments tailored to identify the most promising demand patterns for introducing ride-pooling services by varying the number of centers, the dispersion of destinations around each of these centers and the trip length distribution. When matching trips into rides, we do not only ensure their mutual compatibility in time and space but also that shared rides are only composed by travellers who find the ride-pooling offer to be more attractive than the private ride-hailing alternative given the trade-offs between travel time, fare and discomfort. We measure the shareability potential using a series of metrics related to the extent to which passenger demand can be assigned to shared rides. Our findings indicate that introducing a ride-pooling service can reduce vehicle-hours by 18-59% under a fixed demand level and depending on the concentration of travel destinations around the center and the trip length distribution. System efficiency correlates positively with the former and negatively with the latter. A shift from a monocentric to a polycentric demand pattern is found to have a limited impact on the prospects of shared rides.

description: Although driver distraction has been a known problem for many years, there is a lack of research exploring distraction in the context of autonomous vehicles and non-traditional physical positions drivers may adapt when cars are driving themselves. Thus, our study attempted to investigate the effects of driver distraction and physical positions on the performance and safety of vehicles with self-driving capabilities. To achieve this, we developed a simulator for autonomous vehicles using modified software including Carla and Roadrunner. We also constructed a physical car enclosure and created scripted scenarios to evaluate reaction times and other variables. To collect data, we had volunteers drive through our custom map on simulated drives while using autonomous features and engaging in distracting tasks in different physical positions. Our findings have implications for the development of autonomous vehicle technologies and driver monitoring systems.

description: The variation of the dark energy field is found under the assumption that the dark energy is parametric and interacts with the cold dark matter. Considering that the variation of the field could not exceed the Planck mass, we obtain bounds on the coupling and adiabatic coefficients. Three parameterizations of the adiabatic coefficients are considered and two coupling terms where the energy flows from dark energy to dark matter, or the other way around.

description: Proteins are biomolecules that are essential for life and often serve as targets for antimicrobial drugs. During antimicrobial drug design and development, it is common to use a recombinant version of the protein target to assess the efficacy of the compound. However, during expression, heterogeneity in the protein’s structure/sequence can occur. This can result in reduced purity and long-term stability of the protein and thus, it is imperative that the extent of heterogeneity of the proteins used for drug development is addressed. In our project, we assessed the heterogeneity of recombinant Y. pestis DXP reductoisomerase (DXR, IspC). In doing so, we first expressed, harvested, and purified the recombinant protein which was subsequently evaluated using SDS-PAGE. The resulting purified protein was then trypsinized by incubating the protein with the enzyme trypsin at various concentrations and durations and the resulting fragments were visualized using SDS-PAGE. Finally, we compared our digested protein to a theoretical in-silico-derived digest, permitting us to determine the extent of heterogeneity within our recombinant protein.

description: We demonstrate how digital traces of city-bike trips may become useful to identify urban space attractiveness. We exploit their unique feature - stopovers: short, non traffic-related stops made by cyclists during their trips. As we demonstrate on the case-study of Krakow (Poland), when applied to a big dataset, meaningful patterns appear, with hotspots (places with long and frequent stopovers) identified at both the top tourist and leisure attractions as well as emerging new places.
 We propose a generic method, applicable to any spatiotemporal city-bike traces, providing results meaningful to understand both the general urban space attractiveness and its dynamics. With the proposed filtering (to mitigate a selection bias) and empirical cross-validation (to rule-out false-positive classifications) results effectively reveal spatial patterns of urban attractiveness. Valuable for decision-makers and analysts to enhance understanding of urban space consumption patterns by tourists and residents.

description: This DAC cookbook is to include instructions for the DACs on how to calculate different variables for the Argo profile files. This is especially true for some of the additional sensors that are being added to Argo floats. The extra variables increase the complexity of the profile file and extra instructions may be necessary, depending on float and sensor type. It is separate from other data manuals because users do not need to understand all these details, but that it is important that all DACs to be calculating the variables in the same manner. There are instructions in this cookbook that apply to all floats and some that apply to only certain float types. Look through the table of contents for the specific float types included.

description: This paper reports on the spin glass-like coexistence of competing magnetic orders in oxygen-deficient V2O5 nanoparticles having a broad size distribution. X-ray photoelectron spectroscopy yields the surface chemical stoichiometry of nearly V2O4.65 due to significant defect density. Temperature-dependent electrical conductivity and thermopower measurements demonstrate a polaronic conduction mechanism with a hopping energy of about 0.112 eV. The V2O5-δ sample exhibits strong field as well as temperature-dependent magnetic behaviour when measured with a SQUID magnetometer, showing positive magnetic susceptibility across the temperature range of 2-350 K. Field-cooled and zero-field-cooled data indicate hysteresis, suggesting glassy behaviour. The formation of small polarons due to oxygen vacancy defects, compensated by V4+ charge defects, results in Magneto-Electronic Phase Separation (MEPS) and various magnetic exchanges, as predicted by first-principle calculations. This is evidenced by the strong hybridisation of V orbitals in the vicinity of vacant oxygen site. An increase in V4+ defects shows an antiferromagnetic (AFM) component. The magnetic diversity in undoped V2O4.9 originates from defect density and their random distribution, leading to MEPS. This involves localised spins in polarons and ferromagnetic (FM) clusters on a paramagnetic (PM) background, while V4+ dimers induce AFM interactions. Electron paramagnetic resonance spectra measured at different temperatures indicate a dominant paramagnetic signal at a g-value of 1.97 due to oxygen defects, with a broad FM resonance-like hump. Both signals diminish with increasing temperature. Neutron diffraction data rules out long-range magnetic ordering, reflecting the composition as V2O4.886. Despite the FM hysteresis, no long-range order is observed in ND data, consistent with the polaron cluster-like FM with MEPS nature.

description: We compute analytically the joint probability density of eigenvalues and the level spacing statistics for an ensemble of random matrices with interesting features. It is invariant under the standard symmetry groups (orthogonal and unitary) and yet the interaction between eigenvalues is not Vandermondian. The ensemble contains real symmetric or complex hermitian matrices $\mathbf{S}$ of the form $\mathbf{S}=\sum_{i=1}^M \langle \mathbf{O}_i \mathbf{D}_i\mathbf{O}_i^{\mathrm{T}}\rangle$ or $\mathbf{S}=\sum_{i=1}^M \langle \mathbf{U}_i \mathbf{D}_i\mathbf{U}_i^\dagger\rangle$ respectively. The diagonal matrices $\mathbf{D}_i=\mathrm{diag}\{λ_1^{(i)},\ldots,λ_N^{(i)}\}$ are constructed from real eigenvalues drawn \emph{independently} from distributions $p^{(i)}(x)$, while the matrices $\mathbf{O}_i$ and $\mathbf{U}_i$ are all orthogonal or unitary. The average $\langle\cdot\rangle$ is simultaneously performed over the symmetry group and the joint distribution of $\{λ_j^{(i)}\}$. We focus on the limits i.) $N\to\infty$ and ii.) $M\to\infty$, with $N=2$. In the limit i.), the resulting sum $\mathbf{S}$ develops level repulsion even though the original matrices do not feature it, and classical RMT universality is restored asymptotically. In the limit ii.) the spacing distribution attains scaling forms that are computed exactly: for the orthogonal case, we recover the $β=1$ Wigner's surmise, while for the unitary case an entirely new universal distribution is obtained. Our results allow to probe analytically the microscopic statistics of the sum of random matrices that become asymptotically free. We also give an interpretation of this model in terms of radial random walks in a matrix space. The analytical results are corroborated by numerical simulations.

description: This report provides: 1. A review of the present status of the 16 Ferrybox systems currently operated by JERICO partners. 2. Access to detailed information on the Ferrybox systems on line at the FerryBox project web site (www.ferrybox.org) at the link http://www.ferrybox.org/routes/northern_europe/index.html.en. 3. A set of recommendations and guidance for setting up a new Ferrybox system, based on the experience of the current status of the operation of Ferrybox systems. Next steps are considered in an overview of potential advances resulting from the work of the JERICO project. 4. Part of the JERICO vision is the improved harmonisation of activities through the sharing of information and the standardisation of operating procedures connecting operations at sea and generation of real time data through to the archiving of fully quality controlled and documented data sets. Items following on from the 1st JERICO Workshop are discussed. 5. Ferrybox information is being used to review the current status of and best technical practice for operating Ferrybox systems as part of JERICO work packages WP4 (Harmonizing Operation and Maintenance Methods) and WP5 (Data Management and Distribution). For example, delayed-mode Ferrybox data activities will be routed through WP Task 5.2. This task will also manage the necessary interaction between JERICO and SeaDataNet II. JERICO needs to think how this will be developed in practice across the different user groups and the training required. 6. A task of the JERICO meeting in Crete (October 2012) should be to define a “roadmap” for fully developing the links between MyOcean and the potential providers of near real time data from Ferryboxes that are useful in the context of the activities of MyOcean.

description: We prove a general mirror duality theorem for a subalgebra $U$ of a simple conformal vertex algebra $A$ and its commutant $V=\mathrm{Com}_A(U)$. Specifically, we assume that $A\cong\bigoplus_{i\in I} U_i\otimes V_i$ as a $U\otimes V$-module, where the $U$-modules $U_i$ are simple and distinct and are objects of a semisimple braided ribbon category of $U$-modules, and the $V$-modules $V_i$ are semisimple and contained in a (not necessarily rigid) braided tensor category of $V$-modules. We also assume $U=\mathrm{Com}_A(V)$. Under these conditions, we construct a braid-reversed tensor equivalence $τ: \mathcal{U}_A\rightarrow\mathcal{V}_A$, where $\mathcal{U}_A$ is the semisimple category of $U$-modules with simple objects $U_i$, $i\in I$, and $\mathcal{V}_A$ is the category of $V$-modules whose objects are finite direct sums of the $V_i$. In particular, the $V$-modules $V_i$ are simple and distinct, and $\mathcal{V}_A$ is a rigid tensor category. As an application, we find a rigid semisimple tensor subcategory of modules for the Virasoro algebra at central charge $13+6p+6p^{-1}$, $p\in\mathbb{Z}_{\geq 2}$, which is braided tensor equivalent to an abelian $3$-cocycle twist of the category of finite-dimensional $\mathfrak{sl}_2$-modules. Consequently, the Virasoro vertex operator algebra at central charge $13+6p+6p^{-1}$ is the $PSL_2(\mathbb{C})$-fixed-point subalgebra of a simple conformal vertex algebra $\mathcal{W}(-p)$, analogous to the realization of the Virasoro vertex operator algebra at central charge $13-6p-6p^{-1}$ as the $PSL_2(\mathbb{C})$-fixed-point subalgebra of the triplet algebra $\mathcal{W}(p)$.

description: Das Ziel der vorliegenden Studie war es zu untersuchen, wie sich die Leistung im österreichischen Schwimmsport hinsichtlich der geschwommenen Zeiten über sämtliche Freistildistanzen (50 m, 100 m, 200 m, 400 m, 800 m, 1500 m) in den A-Finalläufen der österreichischen Langbahnmeisterschaften in der allgemeinen Klasse vom Jahr 2000 bis ein-schließlich 2020 entwickelt hat. Leistungsdaten von 837 Damen und 834 Herren wurden statistisch unter Verwendung der einfaktoriellen Varianzanalyse oder für den Fall, dass die Voraussetzungen nicht gegeben waren unter Verwendung des Kruskal-Wallis Tests ausgewertet. Signifikante Unterschiede innerhalb des untersuchten Zeitraums wurden bei den Damen über 50 m Freistil (P < 0,001), 100 m Freistil (P = 0,001), 200 m Freistil (P = 0,001) und 800 m Freistil (P = 0,006) ermittelt. Bei den Herren konnten über 50 m Freistil (P < 0,001), 100 m Freistil (P < 0,001) und 200 m Freistil (P = 0,008) signifikante Unterschiede über den untersuchten Zeitraum erhoben werden. Keine signifikanten Ergebnisse konnten demnach über 400 m Freistil (P = 0,051) der Damen, und über 400 m Freistil (P = 0,591) und 1500 m Freistil (P = 0,308) der Herren ermittelt werden. Zusammenfassend konnten Damen in den letzten 20 Jahren über 50 m, 100 m, 200 m und 800 m Freistil eine Leistungsverbesserung erzielen, während Herren dies über 50 m, 100 m und 200 m Freistil gelang.
description: The aim of the present study was to investigate changes in performance in Austrian swimming with regard to the finishing times over freestyle distances (50 m, 100 m, 200 m, 400 m, 800 m, 1500 m) in the A-finals of the Austrian long track championships in the general class from the year 2000 up to and including 2020. Performance data from 837 women and 834 men were statistically evaluated using one-way ANOVA or, in the event that the normality was harmed, using the Kruskal-Wallis test. Significant differences within the examined period were found for women over 50 m freestyle (p < 0,001), 100 m freestyle (p = 0,001), 200 m freestyle (p = 0,001) and 800 m freestyle (p = 0,006). For men, significant differences were recorded over 50 m freestyle (p < 0,001), 100 m freestyle (p < 0,001) and 200 m freestyle (p = 0,008) over the period investigated. Therefore, no significant results could be determined over 400 m freestyle (p = 0,051) for women and over 400 m freestyle (p = 0,591) and 1500 m freestyle (p = 0,308) for men. To summarize, over the last 20 years women have been able to improve their performance in the 50 m, 100 m, 200 m and 800 m freestyle event, while men have achieved this in the 50 m, 100 m and 200 m free-style event.

description: Stochastic sampling based trackers have shown good performance for abrupt motion tracking so that they have gained popularity in recent years. However, conventional methods tend to use a two-stage sampling paradigm, in which the search space needs to be uniformly explored with an inefficient preliminary sampling phase. In this paper, we propose a novel sampling-based method in the Bayesian filtering framework to address the problem. Within the framework, nearest neighbor field estimation is utilized to compute the importance proposal probabilities, which guide the Markov chain search towards promising regions and thus enhance the sampling efficiency; given the motion priors, a smoothing stochastic sampling Monte Carlo algorithm is proposed to approximate the posterior distribution through a smoothing weight-updating scheme. Moreover, to track the abrupt and the smooth motions simultaneously, we develop an abrupt-motion detection scheme which can discover the presence of abrupt motions during online tracking. Extensive experiments on challenging image sequences demonstrate the effectiveness and the robustness of our algorithm in handling the abrupt motions.

description: A crucial requirement for quantum computing, in particular for scalable quantum computing and error correction, is a fast and high-fidelity qubit readout. For semiconductor based qubits, one limiting factor for local low-power signal amplification, is the output swing of the charge sensor. We demonstrate GaAs and Si/SiGe asymmetric sensing dots (ASDs) specifically designed to provide a significantly improved response compared to conventional charge sensing dots. Our ASD design features a strongly decoupled drain reservoir from the sensor dot, which mitigates negative feedback effects found in conventional sensors. This results in a boosted output swing of $3\,\text{mV}$, which exceeds the response in the conventional regime of our device by more than ten times. The enhanced output signal paves the way for employing very low-power readout amplifiers in close proximity to the qubit.

description: Drug development often employs the use of recombinant proteins to produce vaccines, treat cancers, and develop antibiotics. However, heterogeneity in the protein’s structure can occur, confounding experimental results which can lead to inaccuracies in data acquisition and interpretation. Thus, assessing and minimizing the extent of heterogeneity during expression and purification of recombinant proteins is crucial. In our project, we assessed the heterogeneity of purified recombinant F. tularensis DXP reductoisomerase (DXR, IspC), an enzyme found within the MEP pathway. To do so, we first expressed and harvested an engineered E. coli strain which contained our recombinant protein of interest. The protein was subsequently purified using column chromatography and the results evaluated by SDS-PAGE. Next, our protein was trypsinized resulting in a fragmentation pattern unique to our recombinant F. tularensis IspC. Finally, by using in-silico trypsinization, we compared our results to a theoretical digest, enabling us to determine the extent of heterogeneity within our recombinant protein.

description: We construct a cocycle that, for a given $n$-manifold, maps pairs of asymptotically locally hyperbolic (ALH) metrics to a tractor-valued $(n-1)$-form field on the conformal infinity. This requires the metrics to be asymptotically related to a given order that depends on the dimension. It then provides a local geometric quantity on the boundary that is naturally associated to the pair and can be interpreted as a relative energy-momentum density. It is distinguished as a geometric object by its property of being invariant under suitable diffeomorphisms fixing the boundary, and that act on (either) one of the argument metrics. Specialising to the case of an ALH metric $h$ that is suitably asymptotically related to a locally hyperbolic conformally compact metric, we show that the cocycle determines an absolute invariant $c(h)$, which still is local in nature. This tractor-valued $(n-1)$-form field on the conformal infinity is canonically associated to $h$ (i.e. is not dependent on other choices) and is equivariant under the appropriate diffeomorphisms. Finally specialising further to the case that the boundary is a sphere and that a metric $h$ is asymptotically related to a hyperbolic metric on the interior, we show that the invariant $c(h)$ can be integrated over the boundary. The result pairs with solutions of the KID (Killing initial data) equation to recover the known description of hyperbolic mass integrals of Wang, and Chruściel--Herzlich.

description: Recombinant proteins are commonly utilized in the drug discovery pipeline as a means of assessing the potential drug’s potency. However, when expressed, heterogeneity in the protein’s sequence and/or structure can occur, thereby affecting experimental results. Thus, it is important to assess the degree of heterogeneity during the expression and purification of recombinant proteins. Hence, this project focused on assessing the heterogeneity of purified recombinant E. coli DXP reductoisomerase (DXR, IspC) by comparing the trypsin digested fragments of the recombinant protein to a database. This was first accomplished by expressing, harvesting, and purifying the recombinant E. coli IspC. After purification, the protein was assessed for purity via SDS-PAGE. Then, trypsin digestion was performed on the purified protein by exposing them to 3 different ratios of trypsin for two different incubation times. The resulting fragments were run via SDS-PAGE and the results compared to an in-silico digest. Herein, we present the results of this analysis.

title: Construction of tertiary centers through carbenoid mediated homologation of carbonyl electrophiles
Creators: name: Abdullah, Rudaba
Year: 2021

description: Zur Untersuchung und Konstruktion von tertiären Zentren, konnte ich meine praktische Arbeit durch die Methode der Homologation von Carbenoiden realisieren und einen Beitrag zur Arbeitsgruppe leisten. So gelang es mir, eigenständig zwölf Verbindungen im Zuge meiner Diplomarbeit zu synthesieren und diese sowohl qualitativ als auch quantitativ zu erfassen. (siehe Kapitel 5) Dabei beschäftigt sich die Anwendung mit dem Einsatz eines Carbanions, der unter gegebenen Reaktionsbedingungen durch seine Reaktivität fähig ist weitere und diversere Verbindungen zu erzeugen. Diese Arbeit beschreibt somit eine einfache und effektive Synthese von verschiedenen chemischen Verbindungen mit tertiären Zentren, die sonst durch ihre Funktionalitäten, Strukturen und Substituenten stark gekennzeichnet und so schwer zu erzeugen sind.
description: For the purpose of investigating and constructing tertiary centres, I was able to carry out my work using the method comprising homologation with the aid of carbenoids, and make a contribution to the working group. Thus I succeeded in independently synthesising twelve compounds in the course of my diploma thesis and in assessing these both qualitatively and quantitatively. (See Chapter 5) The application is concerned with the use of a carbanion which, under the given reaction conditions is capable, thanks to its reactivity, of generating additional and more diverse compounds. Hence this thesis describes a simple and effective synthesis of different chemical compounds with tertiary centres which otherwise stand out significantly for their functionalities, structures and substituents, and are difficult to produce.

description: Η παρούσα έρευνα με τίτλο «Η συμβολή του ηγέτη διευθυντή στην επαγγελματική ανάπτυξη των εκπαιδευτικών» στο πλαίσιο της διπλωματικής εργασίας στο μεταπτυχιακό πρόγραμμα «Δημόσια Οικονομική και Πολιτική» του Πανεπιστημίου Δυτικής Αττικής. Ο κύριος σκοπός ήταν να διαπιστωθεί αν οι διευθυντές, ως ηγέτες, ενθαρρύνουν τα κίνητρα των εκπαιδευτικών για επαγγελματική ανάπτυξη. Τα δεδομένα που συλλέχθηκαν, αφορούσαν σε ερωτηματολόγια και συνεντεύξεις. Η ανάλυση των ποσοτικών δεδομένων υποστηρίχθηκε από το λογισμικό πρόγραμμα SPSS. Η ανάλυση των συνεντεύξεων θα συμβάλλει στη τριγωνοποίηση των αποτελεσμάτων της έρευνας. Στόχος ήταν να προκύψει ένα έγκυρο και αξιόπιστο δείγμα και να δημιουργηθεί ένα σαφές συμπέρασμα για τον τρόπο και το βαθμό επιρροής των ηγετών διευθυντών των σχολικών μονάδων προς τους εκπαιδευτικούς ηλεκτρολόγους μηχανικούς στο περιβάλλον του σχολείου για την εμπλοκή τους σε προγράμματα που αφορούν στην επαγγελματική τους ανάπτυξη. Σύμφωνα με τα αποτελέσματα της έρευνας, οι ηγέτες διευθυντές, είναι ο βασικός τύπος ηγέτη που επηρεάζει τους εκπαιδευτικούς προς αυτή τη κατεύθυνση. Πιο συγκεκριμένα, η πλειοψηφία των εκπαιδευτικών που συμμετείχαν στην έρευνα, θεωρεί πως το υποστηρικτικό και το δημοκρατικό στυλ, είναι αυτό που υπερισχύει στους διευθυντές τους, χωρίς όμως όπως φαίνεται να έχει ιδιαίτερη σημασία το στυλ διοίκησης, προς τη σχετική επιρροή τους προς αυτούς. Αξιοσημείωτο είναι ότι υπάρχει αλλαγή στάσης των εκπαιδευτικών ως προς τις μεθόδους και τις προσεγγίσεις τους στη διδασκαλία μετά την συμμετοχή τους σε σχετικά προγράμματα έπειτα από την παρακίνηση τους από το διευθυντή της σχολικής μονάδας που υπηρετούν. Το γεγονός αυτό αναδεικνύει τη σημαντικότητα της παρότρυνσής τους από τους διευθυντές για συμμετοχή σε αντίστοιχα προγράμματα περί επαγγελματικής ανάπτυξης σε ένα επαγγελματικό περιβάλλον όπου λειτουργεί ως οργανισμός μάθησης. Η βασική παρακίνηση των διευθυντών βασίζεται στη χρήση των κινήτρων που αφορούν στην παρότρυνση για κοινωνική συμμετοχή και ικανοποίηση, αλλά και σε αυτά που αφορούν στα οικονομικά, ειδικά όταν αυτά οδηγούν σε επαγγελματική εξέλιξη. Τέλος, τα δημογραφικά που αφορούν στο φύλο, τη σχέση εργασίας και την ηλικία φαίνεται πως έχουν στατιστική διαφορά στην αλλαγή συμπεριφοράς πριν και μετά τη συμμετοχή τους σε σχετικό πρόγραμμα επαγγελματικής ανάπτυξης. Το ίδιο συμβαίνει και σε ότι αφορά την κοινωνική τους ικανοποίηση και την επαγγελματική τους εξέλιξη αντίστοιχα.

description: We present a method to compute the magnetic susceptibility of spin systems at all temperatures in one and two dimensions. It relies on an approximation of the entropy versus energy (microcanonical potential function) on the whole range of energies. The intrinsic constraints on the entropy function and a careful treatment of boundary behaviors allow to extend the standard high temperature series expansions (HTE) towards zero temperature, overcoming the divergence of truncated HTE. This method is benchmarked against two one-dimensional solvable models: the Ising model in longitudinal field and the XY model in a transverse field. With ten terms in the HTE, we find a spin susceptibility within a few \% of the exact results in the whole range of temperature. The method is then applied to two two-dimensional models: the supposed-to-be gapped Heisenberg model and the $J_1$-$J_2$-$J_d$ model on the kagome lattice.
