description: Bethe ansatz solutions of the two-axis countertwisting Hamiltonian for any (integer and half-integer) $J$ are derived based on the Jordan-Schwinger (differential) boson realization of the $SU(2)$ algebra after desired Euler rotations, where $J$ is the total angular momentum quantum number of the system. It is shown that solutions to the Bethe ansatz equations can be obtained as zeros of the extended Heine-Stieltjes polynomials. Two sets of solutions, with solution number being $J+1$ and $J$ respectively when $J$ is an integer and $J+1/2$ each when $J$ is a half-integer, are obtained. Properties of the zeros of the related extended Heine-Stieltjes polynomials for half-integer $J$ cases are discussed. It is clearly shown that double degenerate level energies for half-integer $J$ are symmetric with respect to the $E=0$ axis. It is also shown that the excitation energies of the `yrast' and other `yrare' bands can all be asymptotically given by quadratic functions of $J$, especially when $J$ is large.

Για την επίτευξη του ανωτέρου σκοπού, ακολουθήθηκε η προσέγγιση της ποσοτικής έρευνας, στην οποία συμμετείχαν 119 εκπαιδευτικοί ΠΕ02 δευτεροβάθμιας εκπαίδευσης που υπηρετούσαν το σχολικό έτος 2021-2022 σε γυμνάσια και λύκεια όλης της Ελλάδας. Από τα αποτελέσματα της έρευνας φαίνεται ότι η πλειοψηφία των εκπαιδευτικών της έρευνας γνωρίζουν για την ύπαρξη ψηφιακού εκπαιδευτικού υλικού στο διαδίκτυο. Στην περίπτωση του Ψηφιακού Σχολείου σημειώθηκε ότι αυτή η πλατφόρμα αξιοποιείται σε μεγάλο βαθμό και σε καλή συχνότητα, σε αντίθεση με τις εφαρμογές του Αισώπου και του Πρωτέα, όπου τα ποσοστά αξιοποίησής τους και μετέπειτα η συχνότητα χρήσης τους δεν έχουν το ίδιο ευνοϊκά αποτελέσματα.

description: The purpose of this master's thesis is to write down the extent and the factors of utilization of available digital educational material by Greek philologists and more specifically studies three online platforms, the Digital School, the Aesop and the Proteus. To achieve the above goal, the quantitative research approach was followed, in which 119 philological teachers of secondary education who served the school year 2021-2022 in high schools all over Greece participated. From the results of the research, it seems that the majority of the research teachers are aware of the existence of digital educational material on the internet. In the case of the Digital School, it was noted that this platform is utilized to a large extent and in good frequency, in contrast to the applications of Aesop and Proteus, where their utilization rates and subsequent frequency of use do not have the same favorable results. Finally, some of the factors that act as a deterrent to this whole effort were identified

description: Microplastic (MP) pollution is a well document threat to our aquatic and terrestrial ecosystems, however, the mechanisms by which MPs are transported in river flows are still unknown. The transport of MPs and natural sediment in aquatic flows could be somewhat comparable, as particles are similar in size. However, it is unknown how the lower density of MPs and their different material properties impact their transport dynamics. To answer this, novel laboratory experiments on bed load saltation dynamics in an open-channel flow, using high-speed camera imaging and the detection of 11,035 individual saltation events were used to identify the similarities and differences between spherical MPs and spherical natural sediments transport. The tested MPs varied in terms of size and material properties (density and elasticity). Our analysis shows that the Rouse number accurately describes saltation length, height, transport velocity and collision angles equally well for both MPs and natural sediments. Through statistical inference, the distribution functions of saltation trajectory characteristics for MPs were analogous to natural sediment with only one sediment experiment (1.4 % of cases) differing from all other plastic experiments. Similarly, only nine experiments (9.3 % of cases) showed that collision angles for MPs differed from those of natural sediment experiments. Differences observed in terms of restitution become negligible in overall transport dynamics as turbulence overcomes the kinetic energy lost at particle-bed impact, which keeps particle motion independent from impact. Overall, spherical MP particles behave similarly to spherical natural sediments in aquatic environments under the examined experimental conditions. This is significant because there is an established body of knowledge for sediment transport that can serve as a foundation for the study of MP transport.

description: We examine the bolometric lightcurves of five Type II-P supernovae (SNe 1998A, 2000cb, 2006V, 2006au and 2009E) which are thought to originate from blue supergiant progenitors using a new python package named SuperBoL. With this code, we calculate SNe lightcurves using three different techniques common in the literature: the quasi-bolometric method, which integrates the observed photometry, the direct integration method, which additionally corrects for unobserved flux in the UV and IR, and the bolometric correction method, which uses correlations between observed colors and V-band bolometric corrections. We present here the lightcurves calculated by SuperBoL along with previously published lightcurves, as well as peak luminosities and Ni-56 yields. We find that the direct integration and bolometric correction lightcurves largely agree with previously published lightcurves, but with what we believe to be more robust error calculations, with $0.2 \leq δL_{bol}/L_{bol} \leq 0.5$. Peak luminosities and Ni-56 masses are similarly comparable to previous work. SN 2000cb remains an unusual member of this sub-group, owing to the faster rise and flatter plateau than the other supernovae in the sample. Initial comparisons with the NLTE atmosphere code PHOENIX show that the direct integration technique re-produces the luminosity of a model supernova spectrum to ~5% when given synthetic photometry of the spectrum as input. Our code is publicly available. The ability to produce bolometric lightcurves from observed sets of broad-band light curves should be helpful in the interpretation of other types of supernovae, particularly those that are not well characterized, such as extremely luminous supernovae and faint fast objects.

description: We explore interactions of elastic waves propagating in plates (with soil parameters) structured with concrete pillars buried in the soil. Pillars are 2 m in diameter, 30 m in depth and the plate is 50 m in thickness. We study the frequency range 5 to 10 Hz, for which Rayleigh wave wavelengths are smaller than the plate thickness. This frequency range is compatible with frequency ranges of particular interest in earthquake engineering. It is demonstrated in this paper that two seismic cloaks' configurations allow for an unprecedented flow of elastodynamic energy associated with Rayleigh surface waves. The first cloak design is inspired by some approximation of ideal cloaks' parameters within the framework of thin plate theory. The second, more accomplished but more involved, cloak design is deduced from a geometric transform in the full Navier equations that preserves the symmetry of the elasticity tensor but leads to Willis' equations, well approximated by a homogenization procedure, as corroborated by numerical simulations. The two cloaks's designs are strikingly different, and the superior efficiency of the second type of cloak emphasizes the necessity for rigor in transposition of existing cloaks's designs in thin plates to the geophysics setting. Importantly, we focus our attention on geometric transforms applied to thick plates, which is an intermediate case between thin plates and semi-infinite media, not studied previously. Cloaking efficiency (reduction of the disturbance of the wave wavefront and its amplitude behind an obstacle) and protection (reduction of the wave amplitude within the center of the cloak) are studied for ideal and approximated cloaks' parameters. These results represent a preliminary step towards designs of seismic cloaks for surface Rayleigh waves propagating in sedimentary soils structured with concrete pillars.

description: [abridged] We analyzed mid-infrared high-contrast coronagraphic images of the beta Pictoris system, taking advantage of the NEAR experiment using the VLT/VISIR instrument. The goal of our analysis is to investigate both the detection of the planet beta Pictoris b and of the disk features at mid-IR wavelengths. In addition, by combining several epochs of observation, we expect to constrain the position of the known clumps and improve our knowledge on the dynamics of the disk. To evaluate the planet b flux contribution, we extracted the photometry and compared it to the flux published in the literature. In addition, we used previous data from T-ReCS and VISIR, to study the evolution of the position of the southwest clump that was initially observed in the planetary disk back in 2003. While we did not detect the planet b, we were able to put constraints on the presence of circumplanetary material, ruling out the equivalent of a Saturn-like planetary ring around the planet. The disk presents several noticeable structures, including the known southwest clump. Using a 16-year baseline, sampled with five epochs of observations, we were able to examine the evolution of the clump: the clump orbits in a Keplerian motion with an sma of 56.1+-0.4 au. In addition to the known clump, the images clearly show the presence of a second clump on the northeast side of the disk and fainter and closer structures that are yet to be confirmed. We found correlations between the CO clumps detected with ALMA and the mid-IR images. If the circumplanetary material were located at the Roche radius, the maximum amount of dust determined from the flux upper limit around beta Pictoris b would correspond to the mass of an asteroid of 5 km in diameter. Finally, the Keplerian motion of the southwestern clump is possibly indicative of a yet-to-be-detected planet or signals the presence of a vortex.

description: Background Controlled diet plays a major role in delaying diseases progression among diabetes patients. Diabetes patients often have difficulty of identifying the recommended type, quality and quantity of diet. Knowledge of a recommended diet for diabetes patients influences patient's food selection and dietary pattern .This study aimed to assess the dietary pattern of type 2 diabetes patients in relation to the recommended dietary guideline and identify the patterns with optimal glycemic control. Objective: To assess the dietary pattern and knowledge of type 2 diabetes mellitus patients on the recommended diet in public hospitals Addis Ababa, Ethiopia. Methods: The study employed Institutional based cross-sectional study design from July 2015 to June 2016.We used a semi quantitative Food Frequency Questionnaire (FFQ) with 67 food items to evaluate the dietary pattern and nutrient intake of type 2 diabetes patients. We identified dietary patterns using factor analysis. The relationship between the dietary patterns and glycemic control was investigated by multivariate regression analysis using STATA version12.1. Result- A total of 385 patients with diabetes were included in the study. Five dietary patterns were identified. The dietary patterns were; (i) the "cereals, vegetable, legumes and fruits", (ii) the "cereal, meat, vegetable and wine", (iii) the "fast food" and (iv) the" vegetable and coffee", (v) the "sweet and dairy product" dietary pattern. Carbohydrate mean intake was higher than the recommended daily allowance while energy is lower but the intake of total fat, protein, and fiber were within the recommended daily allowance. The "cereals, vegetable legumes and fruits", and the "cereal, meat, vegetable and wine" dietary patterns were positively associated with good glycemic control. Poor dietary knowledge was found in more than half (55.8%) of the patients. Conclusion and recommendation.-Being a member of diabetes association and those who got more advice from a doctor were more likely to follow healthy dietary pattern. Those who follows varied pattern (vegetable, fruit, legumes & cereal) based had good control of glycemia. More than half of the patients had poor dietary knowledge. Integrating dietary education in the management of diabetes mellitus could lead to better outcome. Key words -Type 2 diabetes, dietary pattern, knowledge, semi quantitative FFQ, Factor analysis

Η παρούσα συστηματική ανασκόπηση φιλοδοξεί να προσδιορίσει ποσοτικά τη μεταβολή των εξετάσεων screening για τις εν λόγω κακοήθειες την περίοδο της πανδημίας συγκριτικά με τα προ πανδημίας επίπεδα, να διερευνήσει τα αίτια της μεταβολής, να παρουσιάσει προτάσεις ανάδειξης του προσυμπτωματικού ελέγχου και να εξετάσει τη βιβλιογραφία για πιθανή επιδείνωση της θνησιμότητας στο μέλλον που οφείλεται στη διατάραξη του screening. Οι μεγάλες μειώσεις, που διαπιστώθηκαν από το σύνολο της βιβλιογραφίας, κορυφώθηκαν κατά τη διάρκεια του πρώτου πανδημικού κύματος, αλλά συνεχίστηκαν και μετά τη χαλάρωση των περιορισμών εξαιτίας μεταξύ άλλων του φόβου των πολιτών για μετάδοση του ιού και της μεταφοράς υλικών και έμψυχων πόρων από την Πρωτοβάθμια Φροντίδα Υγείας προς την αντιμετώπιση της υγειονομικής κρίσης. Προτείνεται ισχυρή εκστρατεία ενημέρωσης για τα οφέλη του προσυμπτωματικού ελέγχου και τα μέτρα ασφαλείας που λαμβάνονται στις υγειονομικές μονάδες σε συνδυασμό με διαλογή των πολιτών που έχουν υψηλότερες πιθανότητες να οφεληθούν, ενώ ιδιαίτερη αναφορά γίνεται στην αυτοδειγματοληψία τραχηλικού υλικού προς HPV DNA έλεγχο. Τέλος, οι έρευνες που μελετήσαν τις επιπτώσεις στη θνησιμότητα ανέδειξαν δυνητική μελλοντική αύξηση, η κλίμακα της οποίας θα εξαρτηθεί από το πόσο γρήγορα θα καλυφθεί το έλλειμμα των εξετάσεων που έχει συσσωρευθεί
description: The Covid-19 pandemic has massively impacted non-urgent medical care, including screening programs for breast and cervical cancers. The present systematic review aims to quantify the changes in the volume of screening tests for these malignancies during the pandemic period compared to pre-pandemic levels, to investigate the causes of the change, to present suggestions for screening optimization and to review the literature for possible worsening of future mortality due to the screening setback. The large reductions, found throughout the literature, peaked during the first wave but continued after the easing of restrictions due to, among other reasons, citizens' fear of covid-19 transmission and the transfer of resources and people from primary health care to dealing with the health crisis. A strong awareness campaign on the advantages of screening and safety measures taken in health facilities is proposed, in conjunction with triaging citizens who are more likely to benefit. There is special reference to cervical self-sampling for HPV DNA testing. Finally, studies examining the effects on mortality have revealed a potential future increase, the scale of which will depend on how quickly the accumulated test deficit is filled

description: We compute the two-loop O(as*at) corrections to the Higgs boson masses in supersymmetric extensions of the Standard Model with Dirac gaugino masses. We rely on the effective-potential technique, allow for both Dirac and Majorana mass terms for the gluinos, and compute the corrections in both the DRbar and on-shell renormalisation schemes. We give detailed results for the MDGSSM and the MRSSM, and simple approximate formulae valid in the decoupling limit for all currently-studied variants of supersymmetric models with Dirac gluinos. These results represent the first explicit two-loop calculation of Higgs boson masses in supersymmetric models beyond the MSSM and the NMSSM.

Prevalence and Belief in the Continuation of Female Genital Cutting among High School Girls, in Hadiya Zone, Southern Ethiopia, 2011
Creators: name: Tamire, Mulugeta
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Background: Female Genital Cutting (FGC) is a cultural practice affecting 100-140 million girls and women across the world and putting 3 million females at risk every year in Africa. Although the trend is slowly decreasing in Ethiopia the magnitude is still very high as the procedure has no any known benefit but has many consequences. Objective: To assess the prevalence and beliefs in the continuation of FGC among high school girls in Hadiya zone of southern Ethiopia. Methods: A cross-sectional quantitative survey with complementary qualitative method was carried out among high school girls in Hadiya zone from January 2011 to February 2011. There were a total of 10587 female students within 12 governmental high schools in the zone, 797 were systematically selected from four high schools to participate in completing a self-administered questionnaire for this study. There was a response rate of 97.8%. Three focus group discussions with community and in-depth interviews with circumcisers were conducted using a semi-structured guide. Results: Six hundred forty one (82.2%) of the girls were circumcised at a mean age of 9 years. Half of the total participants responded that FGC was being practiced in their village. A majority 675(86.7%) had stated that FGC is harmful, while 606(77.7%) thought that a girl has the right not to be circumcised. More than half, 384(59.9%) of the cutting was performed by traditional circumcisers while 186(30%) of the cutting was performed by health professionals. Group circumcision is common in the area, 429(67%) were circumcised in groups and majority 528(82.5) of the cutting was in their own homes. Few of the circumcised girls, 60(9.4%) supported their status as a circumcised girl and only 5 % believe in the continuation of FGC. Conclusion: While there is an urgent need to stop the practice of FGC in Hadiya zone, cultural, beliefs related to maintain the hygiene of the genitalia and social factors are sustaining the practice. Therefore, there should be collaborative efforts from Governmental and non-Governmental organizations to support and bring change within the entire community.

description: Context: Core accretion models of massive star formation require the existence of massive, starless cores within molecular clouds. Yet, only a small number of candidates for such truly massive, monolithic cores are currently known. Aims: Here we analyse a massive core in the well-studied infrared-dark cloud (IRDC) called the 'dragon cloud' (also known as G028.37+00.07 or 'Cloud C'). This core (C2c1) sits at the end of a chain of a roughly equally spaced actively star-forming cores near the centre of the IRDC. Methods: We present new high-angular resolution 1 mm ALMA dust continuum and molecular line observations of the massive core. Results: The high-angular resolution observations show that this region fragments into two cores C2c1a and C2c1b, which retain significant background-subtracted masses of 23 Msun and 2 Msun (31 Msun and 6 Msun without background subtraction), respectively. The cores do not appear to fragment further on the scales of our highest angular resolution images (0.200 arcsec, 0.005 pc ~ 1000 AU). We find that these cores are very dense (nH2 > 10^6 cm-3) and have only trans-sonic non-thermal motions (Ms ~ 1). Together the mass, density and internal motions imply a virial parameter of < 1, which suggests the cores are gravitationally unstable, unless supported by strong magnetic fields with strengths of ~ 1 - 10 mG. From CO line observations, we find that there is tentative evidence for a weak molecular outflow towards the lower-mass core, and yet the more massive core remains devoid of any star formation indicators. Conclusions: We present evidence for the existence of a massive, pre-stellar core, which has implications for theories of massive star formation. This source warrants follow-up higher-angular-resolution observations to further assess its monolithic and pre-stellar nature.

description: We examine updated prospects for detecting WIMPs in supersymmetric models via direct and indirect dark matter search experiments. We examine several historical and also still viable scenarios: projections for well-tempered neutralinos (WTN), projections from the MasterCode (MC), BayesFits (BF) and Fittino (FO) collaborations, non-thermal wino dark matter (NThW) and finally mixed axion-higgsino dark matter from SUSY with radiatively-driven naturalness (RNS). The WTN is ruled out by recent limits from XENON and LUX collaborations. The NThW scenario, previously on tenuous ground due to gamma-line searches, appears also ruled out by recent combined Fermi-LAT/MAGIC limits combined with new HESS results from continuum gamma rays. Substantial portions of MC parameter space and 1 TeV higgsino parameter space from BF group are ruled out. The 100-300 GeV higgsino-like WIMP from RNS survives due to its possible depleted local abundance (where the axion may make up the bulk of dark matter). Projections from ton-scale noble liquid detectors should discover or rule out WIMPs from the remaining parameter space of these surviving models.

description: Purpose: To provide guidance on data linkage appropriateness and feasibility to plan purposeful and sustainable new linkages that advance pharmacoepidemiology and healthcare research. Planning a new data linkage requires careful evaluation to weigh the resources required with the potential overall benefits. Methods: In response to an International Society for Pharmacoepidemiology (ISPE) call for manuscripts, a working group comprised of members from academic, industry, and government determined priority content areas; appropriateness and feasibility of data linkage was selected. Within this topic, scientific and operational considerations were determined, reviewed, and formulated into key areas, and translated into 12 consensus recommendations. Results: Guidance for feasibility assessment was categorized into five key areas: (1) research objectives and justification; (2) data quality and completeness; (3) the linkage process; (4) data ownership and governance; and (5) overall value added by linkage. Within these key areas, recommendations to consider prior to initiation were developed to evaluate suitability of the linkage to meet research objectives, assess source data completeness and population coverage, and ensure well-defined data governance standards and protections. When creating novel linked datasets, researchers must assess the feasibility of both scientific (data quality and linkage methods) and operational (access, data use and transfer, governance, and cost) aspects. Conclusions: The data linkage feasibility assessment considerations outlined can be used as a guide when designing sustainable linked data resources to generate actionable evidence in healthcare research. These recommendations were constructed for wide applicability and can be adapted depending on the geographic, structural, and data components of the linkage.

description: The purpose of this diploma thesis is the study of the classical principal on the prohibition of the deteriorating status of the defendant in the criminal justice system, as reflected in article 470 of the Code of the Criminal Procedure. In this case, a brief description of the source and origin of the term “non-reformatio in pejus” was made alongside with the incorporation and evolution of this regulation in the Greek legal order. This was followed by the theoretical approach of establishing this principle and, on the contrary the critical point of view against the principle itself. Subsequently, a reference was made to the scope of the “non-reformatio in pejus” to its subjective and objective spectrum, of a wholistic and relative concept of power of the principle and the distinction between the direct or actual and indirect or legal form of deterioration of the position of the defendant, both from theoretical, as well as from a jurisprudential point of view. Furthermore, the question of practicing the considered principle in relation to the benefits of the Criminal Code was raised and followed by the recording of the exceptions, in which the principle in not applicable. Last but not least, the consequences of violating the principle of the deterioration of worsening the position of the defendant were mentioned

description: Human tolerance to cold environments is extremely limited and responses between individuals is highly variable. Such physiological and morphological predispositions place them at high risk of developing cold weather injuries [CWI; including hypothermia and/or non-freezing (NFCI) and freezing cold injuries (FCI)]. The present manuscript highlights current knowledge on the vulnerability and variability of human cold responses and associated risks of developing CWI. This review 1) defines and categorizes cold stress and CWI, 2) presents cold defense mechanisms including biological adaptations, acute responses and acclimatization/acclimation and, 3) proposes mitigation strategies for CWI. This body of evidence clearly indicates that all humans are at risk of developing CWI without adequate knowledge and protective equipment. In addition, we show that while body mass plays a key role in mitigating risks of hypothermia between individuals and populations, NFCI and FCI depend mainly on changes in peripheral blood flow and associated decrease in skin temperature. Clearly, understanding the large interindividual variability in morphology, insulation, and metabolism is essential to reduce potential risks for CWI between and within populations.

description: Στην παρούσα εργασία μελετάται η σύνθεση ηλεκτροκαταλυτών ιριδίου υποστηριγμένο σε αγώγιμο υπόστρωμα υποξειδίου του τιτανίου (Ti4O7) για την ανοδική αντίδραση έκλυσης οξυγόνου σε διατάξεις ηλεκτρόλυσης νερού τύπου ΡΕΜ. Το Ti4O7 αποτελεί ένα πολλά υποσχόμενο υπόστρωμα για καταλύτες ιριδίου, που παρουσιάζει υψηλή σταθερότητα υπό τις όξινες συνθήκες ανόδου. Λόγω της υψηλής αγωγιμότητάς του σε σχέση με το TiO2, μπορεί να ενισχύσει την μεταφορά φορτίου στον καταλύτη και επομένως την κινητική των αντιδράσεων. Για το σκοπό αυτό διερευνήθηκαν δύο μέθοδοι σύνθεσης ηλεκτροκαταλύτη IrO2 σε Ti4O7: (i) με υγρό εμποτισμό (wet impregnation) και φόρτιση 30%wt IrΟ2 και (ii) μία απλή μέθοδος σύνθεσης καταλυτών πυρήνα-κελύφους με φόρτιση 50%wt IrΟ2. Η δεύτερη μέθοδος σύνθεσης πραγματοποιήθηκε σε ένα εύρος τιμών pH από 5 έως 10, για τη διερεύνηση της επίδρασής του στον αποτελεσματικό σχηματισμό δομών πυρήνα-κελύφους. Για τη μελέτη της μορφολογίας και της σύστασης των ηλεκτροκαταλυτών, πραγματοποιήθηκε φυσικοχημικός χαρακτηρισμός με τις τεχνικές XRD, SEM/EDS και BET. O ηλεκτροχημικός χαρακτηρισμός πραγματοποιήθηκε σε κελί τριών ηλεκτροδίων σε περιστρεφόμενο ηλεκτρόδιο υαλώδους άνθρακα, όπου αξιολογήθηκε η ενεργότητα και η σταθερότητα των καταλυτών ως προς την αντίδραση έκλυσης οξυγόνου με τις τεχνικές της κυκλικής βολταμμετρίας, της φασματοσκοπίας ηλεκτροχημικής εμπέδησης και της χρονοποτενσιομετρίας
description: In the present work, the synthesis of iridium oxide (IrO2) electrocatalysts supported on a conductive titanium suboxide substrate (Ti4O7) is studied for the anodic oxygen evolution reaction (OER) in PEM water electrolysis devices. Ti4O7 is a promising substrate for iridium catalysts, showing high stability under acidic anode conditions. Due to its high conductivity compared to TiO2, it can enhance the charge transfer to the catalyst and therefore the kinetics of the reactions. For this purpose, two synthesis methods of IrO2/Ti4O7 were investigated: (i) wet impregnation and (ii) a facile method for synthesis of core-shell catalysts. The later method has been conducted in a wide range (5-10) of pH, to investigate its effect on the effective formation of core-shell structures. To investigate the morphology and composition of the electrocatalysts, physicochemical characterization was carried out using the XRD, SEM/EDS and BET techniques. The electrochemical characterization was carried out in a three-electrode cell on a glassy carbon rotating disk electrode (RDE), where the activity and stability of the catalysts in terms of the oxygen evolution reaction were evaluated with the techniques of cyclic voltammetry, electrochemical impedance spectroscopy and chronopotentiometry

description: We present the Grackle chemistry and cooling library for astrophysical simulations and models. Grackle provides a treatment of non-equilibrium primordial chemistry and cooling for H, D, and He species, including H2 formation on dust grains; tabulated primordial and metal cooling; multiple UV background models; and support for radiation transfer and arbitrary heat sources. The library has an easily implementable interface for simulation codes written in C, C++, and Fortran as well as a Python interface with added convenience functions for semi-analytical models. As an open-source project, Grackle provides a community resource for accessing and disseminating astrochemical data and numerical methods. We present the full details of the core functionality, the simulation and Python interfaces, testing infrastructure, performance, and range of applicability. Grackle is a fully open-source project and new contributions are welcome.

description: In the configuration in which two-level atoms with an initial thermal distribution of their states are sent in succession to a cavity sustaining a single mode of electromagnetic radiation, one atom leaving the cavity as the next one enters it (as in the one-atom maser), Jaynes and Cummings showed that the steady state of the field, when many atoms have traversed the cavity, is thermal with a temperature different than that of the atoms in the off-resonant situation. Having an interaction between two subsystems which maintains them at different temperatures was then understood as leading to an apparent violation of energy conservation. Here we show, by calculating the quantum entropy production in the system, that this difference of temperatures is consistent with having the subsystems adiabatically insulated from each other as the steady state is approached. At resonance the insulation is removed and equilibration of the temperatures is achieved.

description: HIV infection is the "first wave" of the pandemic and AIDS morbidity and mortality is the "second wave". Economic, social and governance impact is the "third wave". This wave is amenable to a wide range of different responses. Understanding and quantifying the impact of HIV/AIDS is a key component of strategic thinking. The objective of this study is to assess the HIV/AIDS impacts and related behavioral factors in the Addis Ababa police force; and it used a cross sectional survey to achieve the above mentioned objective. HIV/AIDS related cause of death contributed three quarters of officers' death, and HIV positive or probable HIV infected patients were using the medical service more frequently and at great cost than other officers. Twenty seven percent of officers had multiple sexual partners in the last 12 months, while 107 (33.4%) officers had been engaged in risky sexual intercourse in the last 12 months. Based on the findings it is concluded that HIV/AIDS is a major cause of death and is set to become an expensive health service burden; and still Police Officers are highly vulnerable to the epidemic but feeling falsely safe. Educational activities on risk of HIV/AIDS, STDs and condom use with benefit of voluntary counselling and testing are recommended.

description: We analytically study the relation between quark confinement and spontaneous chiral-symmetry breaking in QCD. In terms of the Dirac eigenmodes, we derive some formulae for the Polyakov loop, its fluctuations, and the string tension from the Wilson loop. We also investigate the Polyakov loop in terms of the eigenmodes of the Wilson, the clover and the domain wall fermion kernels, respectively. For the confinement quantities, the low-lying Dirac/fermion eigenmodes are found to give negligible contribution, while they are essential for chiral symmetry breaking. These relations indicate no direct one-to-one correspondence between confinement and chiral symmetry breaking in QCD, which seems to be natural because confinement is realized independently of the quark mass.

description: We investigate the infinite temperature dynamics of the complex Sachdev-Ye-Kitaev model (SYK$_4$) complimented with a single particle hopping term (SYK$_2$), leading to the chaos-to-integrable crossover of the many-body eigenstates. Due to the presence of the all-to-all connected SYK$_2$ term, a non-equilibrium prethermal state emerges for a finite time window $t_{th}\propto 2^{a/λ^{2/5}}$ that scales with the relative interaction strength $λ$, between the SYK terms before eventually exhibiting thermalization for all $λ$. The scaling of the plateau with $λ$ is consistent with the many-body Fock space structure of the time-evolved wave function. In the integrable limit, the wavefunction in the Fock space has a stretched exponential dependence on distance. On the contrary, in the SYK$_4$ limit, it is distributed equally over the Fock space points characterizing the ergodic phase at long times.

description: A restrictive assumption in the work on testing for structural breaks in time series consists in the fact that the model is formulated such that the stochastic process under the null hypothesis of "no change-point" is stationary. This assumption is crucial to derive (asymptotic) critical values for the corresponding testing procedures using an elegant and powerful mathematical theory, but it might be not very realistic from a practical point of view. For example, if change point analysis for a particular parameter of the process (such as the variance) is performed, it is not necessary clear why other parameters (such as the mean or higher order moments) have to stay constant under the hypothesis that there is no change point in the parameter of interest. This paper develops change point analysis under less restrictive assumptions and deals with the problem of detecting change points in the marginal variance and correlation structures of a non-stationary time series. A CUSUM approach is proposed, which is used to test the "classical" hypothesis of the form H₀ : θ₁ = θ₂ vs. H₁ : θ₀ ≠ θ₂, where θ₁ and θ₂ denote second order parameters (such as the variance or the lag k-correlation) of the process before and after a change point. The asymptotic distribution of the CUSUM test statistic is derived under the null hypothesis. This distribution depends in a complicated way on the dependency structure of the nonlinear non-stationary time series and a bootstrap approach is developed to generate critical values. The results are then extended to test the hypothesis of a non relevant change point, i.e. H₀ : | θ₀ - θ₂ | ≤ δ , which reflects the fact that inference should not be changed, if the difference between the parameters before and after the change-point is small. In contrast to previous work, our approach does neither require the mean to be constant nor - in the case of testing for lag k-correlation - that the mean, variance and fourth order joint cumulants are constant under the null hypothesis. In particular, we allow that the variance has a change point at a different location than the auto-covariance. The results are illustrated by means of a simulation study, which shows that the new procedures have nice finite sample properties. The central England monthly temperature series are analyzed and significant change points in the variance and lag 1-correlation are found in the winter monthly temperature at the late 19th century.
