description: Variation in environmental conditions during development can lead to changes in life-history traits with long-lasting effects. Here, we study how variation in temperature and host plant (i.e. the consequences of potential maternal oviposition choices) affects a suite of life-history traits in pre-diapause larvae of the Glanville fritillary butterfly. We focus on offspring survival, larval growth rates and relative fat reserves, and pay specific attention to intraspecific variation in the responses (G × E × E). Globally, thermal performance and survival curves varied between diets of two host plants, suggesting that host modifies the temperature impact, or vice versa. Additionally, we show that the relative fat content has a host-dependent, discontinuous response to developmental temperature. This implies that a potential switch in resource allocation, from more investment in growth at lower temperatures to storage at higher temperatures, is dependent on the larval diet. Interestingly, a large proportion of the variance in larval performance is explained by differences among families, or interactions with this variable. Finally, we demonstrate that these family-specific responses to the host plant remain largely consistent across thermal environments. Together, the results of our study underscore the importance of paying attention to intraspecific trait variation in the field of evolutionary ecology.

description: Questo studio, frutto di un’attenta ricerca, pone la problematica della pace e della sicurezza nelle aeree a rischio di conflitti e di tensioni, nella considerazione della diplomazia preventiva e delle misure atte a rafforzare la fiducia e la sicurezza. Si evidenzia il ruolo indispensabile delle organizzazioni internazionali competenti, anche ai fini della disciplina e della limitazione degli armamenti, nell’applicazione delle Convenzioni internazionali in materia. Sul presupposto della connessione esistente tra la pace, la democrazia e lo sviluppo si pone l’accento sull’opportunità di promuovere negli Stati in crisi, nel quadro della cooperazione internazionale organizzata, una adeguata sensibilizzazione ai valori democratici.

description: This paper presents a novel formula for the transition density of the Brownian motion on a sphere of any dimension and discusses an algorithm for the simulation of the increments of the spherical Brownian motion based on this formula. The formula for the density is derived from an observation that a suitably transformed radial process (with respect to the geodesic distance) can be identified as a Wright-Fisher diffusion process. Such processes satisfy a duality (a kind of symmetry) with a certain coalescent processes and this in turn yields a spectral representation of the transition density, which can be used for exact simulation of their increments using the results of Jenkins and Spanò (2017). The symmetry then yields the algorithm for the simulation of the increments of the Brownian motion on a sphere. We analyse the algorithm numerically and show that it remains stable when the time-step parameter is not too small.

Retrofitting buildings for net-zero transformation in cold climate communities
Creators: name: Jayasena, Amindha Senarath
Publisher: name: University of British Columbia
Year: 2024

description: The impact of climate change and global warming has been threatening communities in cold climates because of the temperature sensitivity of the ecosystems and the accelerated ongoing warming conditions. Net-zero communities have become very topical for engineers and climate scientists due to their potential to reduce climate change and the impact of global warming. The residential building sector accounts for a significant portion of the energy consumption in a cold climate-based community. Existing buildings in a community are equally important as the new construction during the efforts to implement net-zero targets in existing communities located in cold climatic regions. Implementing energy retrofits is a well-established approach that can improve the energy efficiency of buildings. However, no clear protocols help identify suitable retrofitting strategies for transforming cold climate-based communities into net-zero communities. Further, the existing methods bear a knowledge gap in adopting life cycle thinking into net-zero-related decision-making. Life cycle thinking is an approach which assists in minimizing the environmental impacts of a product throughout its life. Incorporating a life cycle perspective into decision-making related to achieving net-zero enhances the overall efficacy of energy retrofits, ultimately resulting in long-term societal benefits. The present study aims to develop a decision-supporting framework that would assist the retrofit selection process at the building-level for achieving a net zero community by incorporating the life cycle thinking and the triple-bottom-line sustainability concepts. This study selected the commonly available retrofitting strategies in North America. Identified strategies were assessed for their effectiveness using the BEopt and EnergyPlus simulation platforms on a predefined building typical of the cold climatic regions in North America. In addition, Ecoinvent and RSMeans databases with peer-reviewed publications were used to analyze the life cycle impacts of retrofits in the base building. The impact of considering the life cycle perspective in net-zero-related decision-making was initially highlighted using building energy simulations and impact calculations. Further, a social cost-benefit analysis (SCBA) studied the impacts of social factors in net-zero developments. Finally, the optimal retrofitting strategies were identified using Binary Integer Goal Programming. The developed frameworks and methodologies aid policymakers, business owners, and government authorities in pinpointing optimal retrofitting strategies to transform an existing community in a cold climatic region into a net-zero community at the building level.

description: We study the effect of thermal phase fluctuation on the electron spectral function $A(k,ω)$ in a d-wave superconductor with Monte Carlo simulation. The phase degree of freedom is modeled by a XY-type model with build-in d-wave character. We find a ridge-like structure emerges abruptly on the underlying Fermi surface in $A(k,ω=0)$ above the KT-transition temperature of the XY model. Such a ridge-like structure, which shares the same characters with the Fermi arc observed in the pseudogap phase of the underdoped cuprates, is found to be caused by the vortex-like phase fluctuation of the XY model.

Three-dimensional theory of stimulated Raman scattering

description: We present a three-dimensional theory of stimulated Raman scattering (SRS) or superradiance. In particular we address how the spatial and temporal properties of the generated SRS beam, or Stokes beam, of radiation depends on the spatial properties of the gain medium. Maxwell equations for the Stokes field operators and of the atomic operators are solved analytically and a correlation function for the Stokes field is derived. In the analysis we identify a superradiating part of the Stokes radiation that exhibit beam characteristics. We show how the intensity in this beam builds up in time and at some point largely dominates the total Stokes radiation of the gain medium. We show how the SRS depends on geometric factors such as the Fresnel number and the optical depth, and that in fact these two factors are the only factors describing the coherent radiation.

description: Gli autori si pongono il problema dell’ampia competenza della Corte Suprema argentina illustrando, con rigorosa precisione, gli elementi normativi costituzionali e non costituzionali. Questi ultimi, progressivamente adattati alle esigenze del contesto giuridico nazionale e interazionale, avrebbero inciso sulla suddetta competenza ampliandola. Così la Corte Suprema argentina, agli occhi degli autori, avrebbe perso gradualmente il carattere di eccezionalità proprio di tale organo dello Stato, diventando una terza istanza federale nella quale si vedrebbe oggi un rischio pressochè latente di collasso, o almeno di eccessivo sovraccarico di lavoro. Per questo il saggio propone l’analisi di possibili modelli alternativi, ricorrendo allo studio non solo del modello nordamericano, il quale va studiato anche nei suoi profili storici, ma anche dei diversi sistemi latinoamericani ed europei, sempre nel tentativo, di trovare un modello adatto di competenza per la Corte Suprema argentina e la particolare situazione giuridica del Paese australe, rilevata con acuta e aggiornatissima visione realistica.

description: Open clusters offer a unique possibility to study the time evolution of the radial metallicity gradients of several elements in our Galaxy, because they span large intervals in age and Galactocentric distance, and both quantities can be more accurately derived than for field stars. We re-address the issue of the Galactic metallicity gradient and its time evolution by comparing the empirical gradients traced by a sample of 45 open clusters with a chemical evolution model of the Galaxy. At variance with previous similar studies, we have collected from the literature only abundances derived from high--resolution spectra. The clusters have distances $7 < RGC<22$ kpc and ages from $\sim 30$ Myr to 11 Gyr. We also consider the $α$-elements Si, Ca, Ti, and the iron-peak elements Cr and Ni. The data for iron-peak and $α$-elements indicate a steep metallicity gradient for R_GC<12$ kpc and a plateau at larger radii. The time evolution of the metallicity distribution is characterized by a uniform increase of the metallicity at all radii, preserving the shape of the gradient, with marginal evidence for a flattening of the gradient with time in the radial range 7-12 kpc. Our model is able to reproduce the main features of the metallicity gradient and its evolution with an infall law exponentially decreasing with radius and with a collapse time scale of the order of 8 Gyr at the solar radius. This results in a rapid collapse in the inner regions, i.e. $R_{\rm GC}\lesssim 12$ kpc (that we associate with an early phase of disk formation from the collapse of the halo) and in a slow inflow of material per unit area in the outer regions at a constant rate with time.

Spin excitations in the excitonic spin-density-wave state of the iron pnictides

description: Motivated by the iron pnictides, we examine the spin excitations in an itinerant antiferromagnet where a spin-density wave (SDW) originates from an excitonic instability of nested electron-like and hole-like Fermi pockets. Using the random phase approximation (RPA), we derive the Dyson equation for the transverse susceptibility in the excitonic SDW state. The Dyson equation is solved for two different two-band models, describing an antiferromagnetic insulator and metal, respectively. We determine the collective spin-wave dispersions and also consider the single-particle continua. The results for the excitonic models are compared with each other and also contrasted with the well-known SDW state of the Hubbard model. Despite the qualitatively different SDW states in the two excitonic models, their magnetic response shows many similarities. We conclude with a discussion of the relevance of the excitonic SDW scenario to the iron pnictides.

Recenti linee evolutive della conflittualità tra autonomie regionali e Stato nella Giurisprudenza della Corte Costituzionale.

description: Le osservazioni proposte tendono ad evidenziare una ricostruzione paradigmatica del percorso della giurisprudenza costituzionale in materia di contenzioso tra Stato e Regioni, sia nella più ampia prospettiva della definizione delle reciproche competenze dei due referenti istituzionali, sia nella specifica qualificazione della ripartizione dell’esercizio della funzione legislativa. Il percorso tracciato tiene conto delle diverse specializzazioni del giudizio innanzi alla Corte costituzionale, distinguendo l’ambito dei giudizi di legittimità, sia attivati in via d’azione sia sollevati in via incidentale, da quello dei conflitti di attribuzione. L’analisi vuole caratterizzarsi per il tentativo di operare una ricostruzione, il più possibile sistematica, delle peculiarità tecniche e degli obiettivi funzionali di ciascun modello di giudizio, tenuto conto della particolare angolazione di esame che deriva dal mantenere la costante del quadro dialettico tra Stato e Regioni, facendo quindi riferimento ad uno scenario triangolare – Stato, autonomie regionali e Corte costituzionale quale arbitro istituzionale della interazione tra le prime – che viene fortemente a caratterizzare l’impostazione strutturale dell’ordinamento italiano. Le modalità di analisi tengono conto di una selezione puntuale di significative pronunce intervenute nel quadro di ciascun percorso evolutivo, così da porre un sicuro riscontro giurisprudenziale come presupposto per il richiamo dei profili più significativi delle modifiche recentemente intervenute nel quadro istituzionale di riferimento, ed in particolare in relazione al Titolo V, Parte Seconda, della Costituzione. In questo modo, il percorso tracciato diviene uno spunto per valutare il contributo offerto dalla giurisprudenza della Corte alla costruzione del ‘sistema regionale italiano, così da poter tentare di prevedere, con maggiore consapevolezza, quali canali dialettici e quali scenari di contrapposizione potranno più fortemente radicarsi, nel rinnovato quadro costituzionale, nel futuro sviluppo indirizzato alla valorizzazione delle autonomie.

Prescription opioid medications : behaviour, knowledge, and beliefs of potential risks among youth undergoing oral surgery procedures
Creators: name: Lam, Sarah
Publisher: name: University of British Columbia
Year: 2024

description: Canadian youth have demonstrated the fastest-growing rates of opioid-related hospitalizations in the past decade. Prescription opioid medications, although effective in alleviating severe post-operative pain, also have the potential for misuse and diversion. Oral surgery procedures are often the first exposure to opioids for youth patients. This population has been understudied despite being substantially affected by the opioid crisis. The aim of this study was to determine how informed youth (ages 15 to 24) are about potential risks associated with prescription opioid use following oral surgical procedures. An anonymous, 32-item survey was administered through Qualtrics to youth patients following oral surgical procedures to assess behaviour, knowledge, and beliefs about prescription opioid use. Participants were recruited from ten oral surgery practices in British Columbia during six months. A total of 177 responses were recorded. 121 (68.4%) participants received an opioid prescription, and only 2 (2%) participants stored their medication in a locked location. For those who did not, 80.7% indicated they were not worried about anyone taking it. Of the 84 (69.4%) participants with leftover pills (mean: 17.7 pills/participant), 71 (84.5%) reported still having them in their possession, with 33 (46.5%) intentionally saving them for future need. Compared to females, males were more likely to believe that prescription opioids are safer than other substances (P=0.006), and that they are less likely to get into trouble using them (P=0.046). Multivariate logistic regression models demonstrated that the male sex is a significant predictor of prescription opioid misuse (P=0.043). This study indicates a general lack of knowledge among participants and demonstrates that youth are not well informed of the potential risks associated with prescription opioids. In conclusion, it is essential to implement a practical approach to inform youth of the implications surrounding prescription opioid use and its potential for adverse health outcomes.
Non-linear effects in the cyclotron resonance of a massless quasi-particle in graphene

description: We consider the classical motion of a massless quasi-particle in a magnetic field and under a weak electromagnetic radiation with the frequency $ω$. Due to the non-parabolic, linear energy dispersion, the particle responds not only at the frequency $ω$ but generates a broad frequency spectrum around it. The linewidth of the cyclotron resonance turns out to be very broad even in a perfectly pure material which allows one to explain recent experimental data in graphene. It is concluded that the linear response theory does not work in graphene in finite magnetic fields.

description: Recent 1.2-mm continuum observations have shown the giant HII region NGC3576 to be embedded in the centre of an extended filamentary dust-cloud. The bulk of the filament away from the HII region contains a number of clumps seen only at (sub-)millimetre wavelengths and which may host massive protostellar objects at a very early stage of evolution. We have used the Australia Telescope Compact Array (ATCA) to image the cloud for the NH3(1,1), (2,2) and (4,4) transitions, 22 GHz water masers, and 23 GHz continuum emission. We also utilised the 22-m Mopra antenna to map the region for the molecular lines 13CO (1-0), C18O (1-0), HCO+ (1-0), H13CO+ (1-0), CS (1-0) and N2H+ (1-0).The HII region is observed to be expanding into the molecular cloud, sweeping up a clumpy shell of gas, while the central star cluster is dispersing the molecular gas to the east. Temperatures are highest adjacent to the central HII region, indicating that the embedded cluster of young stars there is heating the gas. Six new water masers were detected in the arms of the filament, all associated with NH3 emission peaks, confirming that star-formation has begun within these cores. Core masses range from 5 to 516 solar masses and most appear to be gravitationally bound. Complementary results by André et al. (2008) imply that seven cores will go on to form massive stars between 15 and 50 solar masses. The large scale velocity structure of the filament is smooth, but at least one clump shows the signature of inward gas motions via asymmetries in the NH3 (1,1) line profiles. The same clump exhibits an enhanced abundance of N2H+, which coupled with an absence of CO indicates depletion onto the dust grain surface. The HII region at the heart of NGC3576 is potentially triggering the formation of massive stars in the bulk of the associated cloud.

description: La trasformazione del Capo d’Istituto in dirigente scolastico ha comportato una nuova disciplina contrattuale di riferimento con un’autonoma e specifica area di contrattazione. Il primo Contratto Collettivo Nazionale di Lavoro, stipulato il 1 marzo 2002, e il Contratto Collettivo Nazionale Integrativo, stipulato il 28 maggio 2002, costituiscono la sedes materiae degli istituti contrattuali di riferimento di questa peculiare figura di dirigente pubblico. La contrattazione collettiva, nazionale integrativa e decentrata, viene analizzata non solo in riferimento alle norme costituzionali e primarie, ivi compresa la recente Legge n. 145/2002, ma anche dall’ottica della concreta efficacia derivante dalla materiale applicazione dell’articolato contrattuale. Quest’ultimo aspetto viene messo in relazione anche al nuovo sistema di rapporti nell’ambito della «scuola dell’ autonomia» per verificare se si è giunti all’effettiva realizzazione di una figura manageriale pubblica: autonoma nelle scelte e veramente responsabile del «prodotto finale».

description: The existence of a CP violating θ term in the QCD Lagrangian and the smallness of that term (θ < 10⁻¹⁰) is known as the Strong CP problem and is an unresolved problem in particle physics. The most favoured solution to the strong CP problem is the Peccei-Quinn mechanism which introduces an additional U(1) symmetry. When this symmetry is spontaneously broken a pseudo-goldstone boson called the axion is produced. Cosmological studies of the axion have shown that it may be produced in abundances through the oscillation of the axion field in the early universe (called the misalignment mechanism) and so can be a source of dark matter. This led to the development of axion haloscopes to search for these axions. Standard axion searches rely on resonant cavities in a strong magnetic field. These axions are thought to be virialized and non-relativistic, this leads to them having a frequency with a small linewidth (on the order of kHz). To detect these axions the cavities must be tuned in discrete steps. In this thesis we will discuss a different method to search for axions based on broadband search ideas. Specifically we will focus on relativistic axions which can be produced under a variety of models. This means that line width of axions from relativistic models will be large (∼ 1 GHz) and this will require a new detection strategy. We will discuss new methods for detecting broadband axions including a search for daily modulations which, up until now, have been ignored in the literature. The idea is to collect the signal over an entire season during a specific hour and fit the resulting power excess as a function of time (measured in hours) during a twenty-four hour period. We will discuss how a genuine signal can be discriminated from a spurious signal and background noise by considering B=0 data and by studying the phase drift of the daily modulations. Finally we will comment on how these broadband searches may be applied to current axion cavity experiments.

description: L’A. mira ad inquadrare nel tema dell’incontro “L’ordinamento costituzionale italiano tra riforma e conservazione” (tenutosi a Urbino l’11 aprile 2003) la “riforma della disciplina del fenomeno religioso [...] realizzata tra il 1984 e il 1985 con gli accordi di Villa Madama e l’avvio delle intese”, una disciplina che, nella singolare alternanza di progetti e finalità in contrapposizione (di qui l’uso della figura retorica dell’ossimoro), rimane ancora incompiuta. Per cui, se da un lato per sei confessioni le relative “intese” sono ormai ufficiali mentre altre minoranze religiose nello Stato italiano continuano ad essere governate dalla legge 1159 del 1929, dall’altro lato lo stesso “diritto delle intese” denuncia sempre più il suo fallimento, e si fa strada l’idea di “una norma generale, che costituirebbe un doppio binario tra confessioni religiose regolate da una norma negoziata e altre disciplinate da norme di diritto comune”. Si auspica dunque un intervento legislativo di fronte ai rischi di erosione dell’area dei diritti umani operata sia a livello del diritto privato, sia, ancor più drammaticamente, a livello di diritto pubblico, dall’“offensiva delle religioni”.

description: Cutting out an infinite tube around $r=0$ formally removes the Schwarzschild singularity, but without a physical mechanism this procedure seems ad hoc and artificial. In this paper we provide justification for such a mechanism by means of non-locality. Motivated by the Gauss law we define a suitable radius variable as the inverse of a regular non-local potential, and use this variable to model a non-singular black hole. The resulting geometry has a de\,Sitter core, and for generic values of the regulator there is \emph{no inner horizon}, saving this model from potential issues via mass inflation. An \emph{outer} horizon only exists for masses above a critical threshold, thereby reproducing the conjectured ``mass gap'' for black holes in non-local theories. The geometry's density and pressure terms decrease exponentially, thereby rendering it an almost-exact vacuum solution of the Einstein equations outside of astrophysical black holes. Its thermodynamic properties resemble that of the Hayward black hole, with the notable exception that for critical mass the horizon radius is zero.

description: The ordered magnetic states of MnWO4 at low temperatures were examined by evaluating the spin exchange interactions between the Mn2+ ions of MnWO4 on the basis of first principles density functional calculations and by performing classical spin analysis with the resulting spin exchange parameters. Our work shows that the spin exchange interactions are frustrated within each zigzag chain of Mn2+ ions along the c-direction and between such chains of Mn2+ ions along the a-direction. This explains the occurrence of a spiral-spin order along the c- and a-directions in the incommensurate magnetic state AF2, and that of a uudd spin order along the c- and a-directions in the commensurate magnetic state AF1. The ferroelectric polarization of MnWO4 in the spiral-spin state AF2 was examined by performing Berry phase calculations for a model superstructure to find that the ferroelectric polarization occurs along the b-direction, in agreement with experiment.

description: Only a fraction of the theoretically predicted nonradial pulsation modes have so far been observed in Delta Scuti stars. Nevertheless, the large number of frequencies detected in recent photometric studies of selected Delta Scuti stars allow us to look for regularities in the frequency spacing of modes. Mode identifications are used to interpret these results. Statistical analyses of several Delta Scuti stars (FG Vir, 44 Tau, BL Cam and others) show that the photometrically observed frequencies are not distributed at random, but that the excited nonradial modes cluster around the frequencies of the radial modes over many radial orders. The observed regularities can be partly explained by modes trapped in the stellar envelope. This mode selection mechanism was proposed by Dziembowski & Krolikowska (1990) and shown to be efficient for l = 1 modes. New pulsation model calculations confirm the observed regularities. We present the s-f diagram, which compares the average separation of the radial frequencies (s) with the frequency of the lowest-frequency unstable radial mode (f). This provides an estimate for the log g value of the observed star, if we assume that the centers of the observed frequency clusters correspond to the radial mode frequencies. This assumption is confirmed by examples of well-studied Delta Scuti variables in which radial modes were definitely identified.

description: We theoretically analyze a possibility of electromagnetic wave emission due to electron transitions between spin subbands in a ferromagnet. Different mechanisms of such spin-flip transitions are cousidered. One mechanism is the electron transitions caused by magnetic field of the wave. Another mechanism is due to Rashba spin-orbit interaction. While two mentioned mechanisms exist in a homogeneously magnetized ferromagnet, there are two other mechanisms that exist in non-collinearly magnetized medium. First mechanism is known and is due to the dependence of exchange interaction constant on the quasimomentum of conduction electrons. Second one exists in any non-collinearly magnetized medium. We study these mechanisms in a non-collinear ferromagnet with helicoidal magnetization distribution. The estimations of probabilities of electron transitions due to different mechanisms are made for realistic parameters, and we compare the mechanisms. We also estimate the radiation power and threshold current in a simple model in which spin is injected into the ferromagnet by a spin-polarized electric current through a tunnel barrier.

description: Der zunehmende technische Fortschritt ermöglicht die Entwicklung von Assistenzfunktionen und die Automatisierung komplexer Prozesse. Hiermit können menschliche Operateure bei der Durchführung komplexer Prozesse signifikant unterstützt werden. Die Mensch-Technik-Interaktion wird sich dadurch zu einer intensiven Mensch-Technik-Kooperation entwickeln. Das kognitive System des Menschen wird mit dem kognitiven System der Technik interagieren. Auch im Kontext des Flugverkehrsmanagements ist eine zunehmende Automatisierung von Prozessen und damit einhergehende veränderte Anforderungen an Operateure zu erwarten. So müssen Flughäfen aufgrund des Single European Sky Performance Scheme Prozesse optimieren, um eine sichere, effiziente und umweltverträgliche Mobilität zu gewährleisten. In diesem Kontext sind die Möglichkeiten der Automatisierung beschränkt. Menschliche Akteure werden auch künftig die Verantwortung für Entscheidungsprozesse übernehmen. Eine Möglichkeit zur Optimierung der Prozesse ist die Kooperation relevanter Stakeholder-Gruppierungen mit Hilfe von Assistenzfunktionalitäten zu unterstützen. Dies stellt allerdings aufgrund gegensätzlicher Interessen und Zielstellungen der beteiligten Stakeholder eine große Herausforderung dar. Zudem unterliegen Entscheidungen bestimmten Einflussgrößen. Diese können das Ergebnis einer Entscheidung, wie z.B. die Qualität der Lösungsvorschläge sowohl positiv als auch negativ beeinflussen. Bisherige Studien beschäftigten sich u.a. mit den Faktoren Motivation, Vorwissen aus Erfahrung, Situationsbewusstsein und Beanspruchung als mögliche Einflussfaktoren auf Entscheidungen. Allerdings können auch Emotionen ein entscheidender Faktor sein, der nicht vernachlässigt werden sollte, v.a. weil der Zusammenhang zwischen Emotionen und Entscheidungen noch nicht abschließend geklärt ist: Sowohl positive als auch negative Emotionen können zum einen positive, zum anderen negative Effekte bewirken. Dies wird im Rahmen des vorliegenden Papers diskutiert. Ziel des vorliegenden Beitrages ist es einen theoretischen Überblick über Aspekte des Entscheidungsprozesses in Teams sowie mögliche Einflussfaktoren auf Entscheidungen zu geben. Dabei wird vor allem eine emotionssensitive Schnittstelle in der Mensch-Maschine-Kooperation diskutiert.
