description: There are numerous examples of phenological shifts that are recognized both as indicators of climate change and drivers of ecosystem change. A pressing challenge is to understand the causal mechanisms by which climate affects phenology. We combined annual population census data and individual longitudinal data (1992–2018) on grey seals, Halicheorus grypus, to quantify the relationship between pupping season phenology and sea surface temperature. A temperature increase of 2°C was associated with a pupping season advance of approximately seven days at the population level. However, we found that maternal age, rather than sea temperature, accounted for changes in pupping date by individuals. Warmer years were associated with an older average age of mothers, allowing us to explain phenological observations in terms of a changing population age structure. Finally, we developed a matrix population model to test whether our observations were consistent with changes to the stable age distribution. This could not fully account for observed phenological shift, strongly suggesting transient modification of population age structure, for example due to immigration. We demonstrate a novel mechanism for phenological shifts under climate change in long-lived, age- or stage-structured species with broad implications for dynamics and resilience, as well as population management.

description: We compute in linearized gravity all the contributions to the gravitational effective action due to a virtual Dirac fermion, related to the conformal anomaly. This requires, in perturbation theory, the identification of the gauge-gauge-graviton vertex off mass shell, involving the correlator of the energy-momentum tensor and two vector currents ($TJJ$), which is responsible for the generation of the gauge contributions to the conformal anomaly in gravity. We also present the anomalous effective action in the inverse mass of the fermion as in the Euler-Heisenberg case.

Igbo ubo-aka : its role and music among the NRI people of Nigeria
Creators: name: Ezegbe, Clement Chukuemeka
Publisher: name: University of British Columbia
Year: 2010

description: This study attempts a socio-cultural approach to ubo-aka musical phenomena in terms of the role of the instrument as a communication medium with rich and varied tradition of its own among the Nri people in Igbo culture of south eastern Nigeria. The Igbo ubp-aka is a plucked idiophone consisting of eight metal prongs which are linguistically tuned with a bowl-shaped gourd resonator. This study is needed in the light of the important socio-cultural roles of ubp-aka musical tradition which are facing the prospect of extermination in the face of social change. The investigation rests primarily on my extensive field work in the music of Nri people from 1966 to 1975 and on current field recordings by Gwamniru Ezegbe and Levi Oji who are my research assistants from 1976 to 1977, in addition to current information on Nri culture from many Nri people. The first chapter introduces the whole thesis by presenting the method of investigation, the problems, the purpose, the academic reason for this study, literary survey and the scope of the study. Chapter 2 describes the Nri people and their culture as they relate to ubo-aka musical tradition. Chapter 3 is an organological study of the instrument based on the systems of Draeger and Hood. The determinants and the socio-cultural roles of ubq-aka music are discussed in ethnographic context which concludes the socio-cultural background to ubo-aka music. Chapter 5 discusses the transcriptions and the analyses using Professor Liang's "graphic space notation" specially designed for ubo-aka music. In the analyses, 30 musical examples that best typify ubo-aka musical tradition in Nri were selected and analyzed in terms of the musical parameters, linguistic content and social functions covering the characteristic scale-modes, the melodic contour typology, the intervalic structures, the correlation between the melodic contour and the speech tones and the rhythms of melody and speech. Chapter 6 concludes the study with recommendations and shows that (1) the melodic contours are linguistically determined by the Igbo tonal language, (2) the rhythms of melody and words do not always agree and (3) that the musical parameters can change but not the socio-cultural roles as defined by the society.

description: Einstein-aether theory is general relativity coupled to a dynamical, unit timelike vector. If this vector is restricted in the action to be hypersurface orthogonal, the theory is identical to the IR limit of the extension of Horava gravity proposed by Blas, Pujolàs and Sibiryakov. Hypersurface orthogonal solutions of Einstein-aether theory are solutions to the IR limit of this theory, hence numerous results already obtained for Einstein-aether theory carry over.

description: Production of tachyons in, among other things, air showers would be in accordance with predictions of general relativity. Some such tachyons would travel with a precisely determined speed, almost equal to 5c/3 relative to the earth, and would be registered high above the region of creation of air showers, e.g. on board of a satellite. A very simple experiment designed to detect these tachyons is outlined here. Brief justification to search for tachyons is also given.

description: The last decade has witnessed very fast development in microfabrication technologies. The increasing industrial applications of microfluidic systems call for more intensive and systematic knowledge on this newly emerging field. Especially for gaseous flow and heat transfer at microscale, the applicability of conventional theories developed at macro scale is not yet completely validated; this is mainly due to scarce experimental data available in literature for gas flows. The objective of this thesis is to investigate these unclear elements by analyzing forced convection for gaseous flows through microtubes and micro heat exchangers. 
Experimental tests have been performed with microtubes having various inner diameters, namely 750 m, 510 m and 170 m, over a wide range of Reynolds number covering the laminar region, the transitional zone and also the onset region of the turbulent regime. The results show that conventional theory is able to predict the flow friction factor when flow compressibility does not appear and the effect of fluid temperature-dependent properties is insignificant.
A double-layered microchannel heat exchanger has been designed in order to study experimentally the efficiency of a gas-to-gas micro heat exchanger. This microdevice contains 133 parallel microchannels machined into polished PEEK plates for both the hot side and the cold side. The microchannels are 200 µm high, 200 µm wide and 39.8 mm long. The design of the micro device has been made in order to be able to test different materials as partition foil with flexible thickness.
Experimental tests have been carried out for five different partition foils, with various mass flow rates and flow configurations. The experimental results indicate that the thermal performance of the countercurrent and cross flow micro heat exchanger can be strongly influenced by axial conduction in the partition foil separating the hot gas flow and cold gas flow.
A comparative evaluation of an infant stimulation program for public health utilizatio
Creators: name: Arlett, Christine
Publisher: name: University of British Columbia
Year: 2010

description: An infant stimulation program developed for mothers from low income areas with children under the age of three years is described. The program was developed for use in a public health setting and involved close collaboration with personnel from a number of community service agencies. The program, which had a duration of eight weeks, involved a combination of group meetings and home visits. Outcome was assessed in terms of developmental quotients and estimates of the quality of the home environment. Three additional programs consisted of a waiting list control and programs in which each of the two intervention components, home visits and group meetings, were offered separately. Assessments were carried out prior to the programs, immediately following them and four months later. Pre-assessments established the equivalence of the four groups on both the dependent measures and socioeconomic indices, although the groups were found to differ on the measure of maternal intelligence obtained. Following intervention, the scores obtained on both dependent measures for the home visits plus group meetings program were found to be significantly greater than those obtained by the waiting list control clients. The effect of the home visits only program was indeterminate as the scores did not differ significantly from either the control group or the home visits plus group meetings program. Clients in the group meetings only program did not differ significantly from control group clients on either measure. Similar results were obtained at follow up assessments, with no evidence of any decline in scores following the end of intervention. Whereas the correlations observed between maternal intelligence and children's developmental quotients remained much the same over the three assessment periods, the correlations between the home environments and the children's developmental quotients increased, both concurrently and predictively, following intervention. These findings were interpreted as providing support for the hypothesis that the changes in the home environments resulting from the programs were indeed important ones in terms of the children's development. There was some evidence to suggest that the socioeconomic indices of age, education and income of mother were positively related to outcome, while, in addition, maternal intelligence was related to the maintenance of treatment effect at follow up. The correlation of socioeconomic status with outcome was consistent with the results of other infant stimulation programs but was not considered to reflect on the effectiveness of the program as all of the clients in the study were of low socioeconomic status. The implications of these results are discussed both in terms of the further development and implementation of the program described and in the context of research in the area of infant stimulation.
Coordination and Control of Autonomous Mobile Robots Swarms

Subjects: ING-INF/04 Automatica

description: This thesis presents some different techniques designed to drive a swarm of robots in an a-priori unknown environment in order to move the group from a starting area to a final one avoiding obstacles. The presented techniques are based on two different theories used alone or in combination: Swarm Intelligence (SI) and Graph Theory. Both theories are based on the study of interactions between different entities (also called agents or units) in Multi- Agent Systems (MAS). The first one belongs to the Artificial Intelligence context and the second one to the Distributed Systems context. These theories, each one from its own point of view, exploit the emergent behaviour that comes from the interactive work of the entities, in order to achieve a common goal. The features of flexibility and adaptability of the swarm have been exploited with the aim to overcome and to minimize difficulties and problems that can affect one or more units of the group, having minimal impact to the whole group and to the common main target. Another aim of this work is to show the importance of the information shared between the units of the group, such as the communication topology, because it helps to maintain the environmental information, detected by each single agent, updated among the swarm. Swarm Intelligence has been applied to the presented technique, through the Particle Swarm Optimization algorithm (PSO), taking advantage of its features as a navigation system. The Graph Theory has been applied by
exploiting Consensus and the application of the agreement protocol with the aim to maintain the units in a desired and controlled formation. This approach has been followed in order to conserve the power of PSO and to control part of its random behaviour with a distributed control algorithm
like Consensus.

description: This study explores the challenges faced by Nigerian undergraduate students in Scotland, UK, focusing on communication culture shock and adaptation strategies. Addressing a gap in literature, it examines the communication techniques used by these students to navigate cultural differences. Anchored in Communication Accommodation Theory (CAT) and Social Identity Theory, the study analyses how students adjust their communication styles and how group identity influences adaptation. Utilising a survey research design, data from 381 Nigerian undergraduate students reveal various adaptation strategies, such as speaking clearly and embracing feedback, to overcome barriers. A survey research design was adopted for this study. The population of this study was made up of Nigerian undergraduate students in Scotland, United Kingdom. According to the Higher Education Statistics Agency (2023), the number of Nigerian undergraduate students in the United Kingdom between the years

2018/2019 through to 2022/2023 is 73,716. Keyton’s formula for sample size determination was used to and the sample size of this study was 381. The snowball sampling was used in different stages. Data were gathered using the copies of the questionnaire which were administered on the respondents virtually. Quantitative data analysis was adopted in this study such as the Statistical Package for the Social Sciences (SPSS), percentages and inferential statistics Chi. The findings revealed that the importance of effective communication in navigating cultural differences, with a consensus on the efficacy of specific techniques. Speaking more slowly and clearly, using less slang and idioms, being more direct and open to feedback and criticism are considered beneficial for effective communication in the UK. The study recommended that Universities in the United Kingdom should foster collaborations with community organizations, Nigerian consular services, and Nigerian cultural associations

description: The 5d transition-metal oxides have been an intriguing platform to demonstrate efficient charge to spin current conversion due to a unique electronic structure dominated by strong spin-orbit coupling. Here, we report on stacking-order effect of spin-orbit torque (SOT), spin-Hall magnetoresistance, and magnetic anisotropy in bilayer Ni$_{81}$Fe$_{19}$-5d iridium oxide, IrO$_2$. While all the IrO$_2$ and Pt control samples exhibit large dampinglike-SOT generation stemming from the efficient charge to spin current conversion, the magnitude of the SOT is larger in the IrO$_2$ (Pt)-bottom sample than in the IrO$_2$ (Pt)-top one. The fieldlike-SOT has even more significant stack order effect, resulting in an opposite sign in the IrO$_2$ samples in contrast to the same sign in the Pt samples. Furthermore, we observe that the magnetic anisotropy energy density and the anomalous Hall effect are increased in the IrO$_2$ (Pt)-bottom sample, suggesting enhanced interfacial perpendicular magnetic anisotropy. Our findings highlight the significant influence of the stack order on spin transport and magnetotransport properties of Ir oxide/ferromagnet systems, providing useful information on design of SOT devices including 5d transition-metal oxides.

description: As a potential technology feature for 6G wireless networks, the idea of sensing-communication integration requires the system not only to complete reliable multi-user communication but also to achieve accurate environment sensing. In this paper, we consider such a joint communication and sensing (JCAS) scenario, in which multiple users use the sparse code multiple access (SCMA) scheme to communicate with the wireless access point (AP). Part of the user signals are scattered by the environment object and reflected by an intelligent reflective surface (IRS) before they arrive at the AP. We exploit the sparsity of both the structured user signals and the unstructured environment and propose an iterative and incremental joint multi-user communication and environment sensing scheme, in which the two processes, i.e., multi-user information detection and environment object detection, interweave with each other thanks to their intrinsic mutual dependence. The proposed algorithm is sliding-window based and also graph based, which can keep on sensing the environment as long as there are illuminating user signals. The trade-off relationship between the key system parameters is analyzed, and the simulation result validates the convergence and effectiveness of the proposed algorithm.

description: We reanalyzed our atom interferometer measurement of the electric polarizability of lithium now accounting for the Sagnac effect due to Earth rotation. The resulting correction to the polarizability is very small but the visibility as a function of the applied phase shift is now better explained. The fact that the Sagnac and polarizability phase shifts are both proportional to $v^{-1}$, where $v$ is the atom velocity, suggests that a phase shift of the Sagnac type could be used as a counterphase to compensate the electric polarizability phase shift. This exact compensation opens the way to higher accuracy measurements of atomic polarizabilities and we discuss how this can be practically done and the final limitations of the proposed technique.

description: Il carcinoma epatocellulare (HCC) è il più frequente tumore maligno del fegato e rappresenta il sesto tipo di tumore piÃ¹ comune nel mondo. Spesso i pazienti con HCC vengono diagnosticati a stadi piuttosto avanzati, quando le uniche opzioni terapeutiche in grado di migliorarne la sopravvivenza sono la chemoembolizzazione dell'arteria epatica ed il trattamento con l'inibitore multi-cinasico, Sorafenib. In questo contesto, la scoperta del ruolo centrale dei microRNA (miRNA) nella tumorigenesi umana risulta di fondamentale importanza per lo sviluppo di nuovi marcatori diagnostici e bersagli terapeutici.
I microRNA (miRNA) sono delle piccole molecole di RNA non codificante, della lunghezza di 19-22 nucleotidi, filogeneticamente molto conservati, ed esercitano un ruolo cruciale nella regolazione di importanti processi fisiologici, quali sviluppo, proliferazione, differenziamento, apoptosi e risposta a numerosi segnali extracellulari e di stress. I miRNA sono inoltre responsabile della fine regolazione dell'espressione di centinaia di geni bersaglio attraverso il blocco della traduzione o la degradazione dell'mRNA target. Studi di profiling hanno evidenziato l'espressione aberrante di specifici miRNA in numerosi tipi di tumore umano.
Lo scopo del presente lavoro è stato quello di individuare un pannello di miRNA deregolati nell'epatocarcinoma umano e di caratterizzare il ruolo biologico di tre miRNA deregolati nell'HCC, al fine di individuare alcuni dei meccanismi molecolari alla base della trasformazione maligna miRNA-associata. La nostra ricerca è stata inoltre focalizzata nell'individuazione di nuovi bersagli e strumenti terapeutici, quali i microRNA, per il trattamento combinato di HCC in stadio intermedio-avanzato.

description: In the study of complex networks (systems), the scaling phenomenon of flow fluctuations refers to a certain power-law between the mean flux (activity) $$ of the $i$th node and its variance $σ_i$ as $σ_i \propto < F_{i} > ^α$. Such scaling laws are found to be prevalent both in natural and man-made network systems, but our understanding of their origins still remains limited. In this paper, a non-stationary Poisson process model is proposed to give an analytical explanation of the non-universal scaling phenomenon: the exponent $α$ varies between 1/2 and 1 depending on the size of sampling time window and the relative strength of the external/internal driven forces of the systems. The crossover behavior and the relation of fluctuation scaling with pseudo long range dependence are also accounted for by the model. Numerical experiments show that the proposed model can recover the multi-scaling phenomenon.
description: There is a mistake in the previous axiv post (indeed the scaling law holds for both \Delta t > \tau and \Delta t < \tau)

description: Single crystals of EuPtSi$_3$, which crystallize in the BaNiSn$_3$-type crystal structure, have been grown by high temperature solution growth method using molten Sn as the solvent. EuPtSi$_3$ which lacks the inversion symmetry and has only one Eu site in the unit cell is found to be an antiferromagnet with two successive magnetic transitions at $T_{\rm N1}$ = 17 K and $T_{\rm N2}$ = 16 K, as inferred from magnetic susceptibility, heat capacity and $^{151}$Eu Mössbauer measurements. The isothermal magnetization data for $H \parallel$ [001] reveal a metamagnetic transition at a critical field $H_{\rm c}$ = 1 T. The magnetization saturates to a moment value of 6.43 $μ_{\rm B}$/Eu above 5.9 T (9.2 T) for $H \parallel $ [001] ([100]), indicating that these fields are spin-flip fields for the divalent Eu moments along the two axes. The origin of this anisotropic behaviour is discussed. A magnetic (H, T) phase diagram has been constructed from the temperature dependence of isothermal magnetization data. The reduced jump in the heat capacity at $T_{\rm N1}$ indicates a transition to an incommensurate, amplitude modulated antiferromagnetic structure. The shape of the hyperfine field split Mössbauer spectrum at $T_{\rm N1}$ provides additional support for the proposed nature of this magnetic transition.

description: Graphene is at the forefront of condensed matter sciences, because of a variety of interesting phenomena it supports. If graphene could support high Tc superconductivity, after doping for example, it will make it even more valuable. Some authors have suggested possibility of superconductivity in graphite like systems. However, an early suggestion of one of us (Baskaran) was unique in the sense it combined Pauling's classic idea of resonating valence bond physics with band theory to obtain some exciting results for superconductivity. Black-Schaffer and Doniach took this approach further and found an unconventional d + id order parameter. To sharpen our theory and get more convincing and reliable results for superconductivity, we introduce a correlated variational BCS ground state wavefunction and perform extensive Monte Carlo study of the repulsive Hubbard model on the honeycomb lattice. We find that undoped graphene is not a superconductor, consistent with experiments and also mean field results. Interestingly, an appreciable superconducting order is obtained around an optimal doping. This result and a supportive slave particle analysis together suggest the possibility of high temperature superconductivity in doped graphene.

description: The demand of energy, fuels and chemicals is increasing due to the strong growth of some countries in the developing world and the development of the world economy. Unfortunately, the general picture derived sparked an exponential increase in crude oil prices with a consequent increase of the chemical, by-products and energy, depleting the global market. Nowadays biomass are the most promising alternative to fossil fuels for the production of chemicals and fuels.
In this work, the development of three different catalytic processes for the valorization of biomass-derived has been investigated.
5-hydroxymethylfurfural oxidation was studied under mild reaction condition using gold and gold/copper based catalysts synthetized from pre-formed nanoparticles and supported onto TiO2 and CeO2. 
The analysis conducted on catalysts showed the formation of alloys gold/copper and a strong synergistic effect between the two metals. For this reason the bimetallic catalysts supported on titania showed a higher catalytic activity respect to the monometallic catalysts.
The process for the production of 2,5-bishydroxymethyl furan (BHMF) was also optimized by means the 5-hydroxymethylfurfural hydrogenation using the Shvo complex. Complete conversion of HMF was achieved working at 90 °C and 10 bar of hydrogen. The complex was found to be re-usable for at least three catalytic cycles without suffering any type of deactivation. 
Finally, the hydrogenation of furfural and HMF was carried out, developing the process of hydrogen transfer by using MgO as a catalyst and methanol as a hydrogen donor. Quantitative yields to alcohols have been achieved in a few hours working in mild condition: 160 °C and at autogenous pressure. The only by-products formed were light products such as CO, CO2 and CH4 (products derived from methanol transformation), easily separable from the reaction solution depressurizing the reactor.
A universal delta model
Un modello universale di delta

description: This thesis presents a universal model of documents and deltas. This model formalize what it means to find differences between documents and to shows a single shared formalization that can be used by any algorithm to describe the differences found between any kind of comparable documents.

The main scientific contribution of this thesis is a universal delta model that can be used to represent the changes found by an algorithm. The main part of this model are the formal definition of changes (the pieces of information that records that something has changed), operations (the definitions of the kind of change that happened) and deltas (coherent summaries of what has changed between two documents). The fundamental mechanism tha makes the universal delta model a very expressive tool is the use of encapsulation relations between changes. In the universal delta model, changes are not always simple records of what has changed, they can also be combined into more complex changes that reflects the detection of more meaningful modifications.

In addition to the main entities (i.e., changes, operations and deltas), the model describes and defines also documents and the concept of equivalence between documents. As a corollary to the model, there is also an extensible catalog of possible operations that algorithms can detect, used to create a common library of operations, and an UML serialization of the model, useful as a reference when implementing APIs that deal with deltas.

The universal delta model presented in this thesis acts as the formal groundwork upon which algorithm can be based and libraries can be implemented. It removes the need to recreate a new delta model and terminology whenever a new algorithm is devised. It also alleviates the problems that toolmakers have when adapting their software to new diff algorithms.
A Mixed Methods Study of Ontario Male Nursing Students' Perceptions of Their Learning Experiences in Perinatal Health Nursing

description: Background: Perinatal health nursing (PHN) which is a core component of undergraduate nursing education includes the theory and clinical practicum (laboratory, simulation, clinical placement) courses. The aim of this research study is to explore the perceptions of male nursing students’ learning experiences in regard to PHN at the University of Ottawa. Methodology: This mixed methods research was completed using the Convergent Parallel Mixed Methods Research Design. The data were collected from nine participants through an online questionnaire and an in-depth qualitative interview guide. Results: The theory and clinical practicum courses in PHN were overall positive learning experiences for the male nursing students, yet there is still room for improvement. Their comfort level with the clinical placement was statistically significant (before and after the clinical placement). The participants identified five facilitators: the clinical instructor, nursing staff, patients and their family members, the two male nurses working in PHN, and the comradery of other students. Three barriers were identified by them: the nursing staff in the hospital settings, the female patients, and specific situations deemed as ‘awkward’. Gender did have an impact on the participants’ PHN learning experiences, however, the positive support of the clinical instructors did facilitate this. Discussion: The male nursing student’ PHN learning experiences can be divided into positive and negative ones. This study’s findings are consistent with those of previous studies, however, this is the first study to assess both the PHN theory and clinical practicum courses in Ontario. Although Andragogy was used as the theoretical framework, it did have its limitations. The Andragogy in Practice Model was introduced to expand Andragogy into practice. Conclusion: Gender bias and fear of rejection crosses all three levels of the contributing factors (individual, institutional and societal). Recommendations include continuing to raise awareness of how gender normative behaviour and social standards impact the PHN learning experiences of male nursing students, and integrating a confidence building workshop in the PHN courses.
Time-dependent active microrheology in dilute colloidal suspensions

description: In a microrheological set-up a single probe particle immersed in a complex fluid is exposed to a strong external force driving the system out of equilibrium. Here, we elaborate analytically the time-dependent response of a probe particle in a dilute suspension of Brownian particles to a large step-force, exact in first order of the density of the bath particles. The time-dependent drift velocity approaches its stationary state value exponentially fast for arbitrarily small driving in striking contrast to the power-law prediction of linear response encoded in the long-time tails of the velocity autocorrelation function. We show that the stationary-state behavior depends nonanalytically on the driving force and connect this behavior to the persistent correlations in the equilibrium state. We argue that this relation holds generically. Furthermore, we elaborate that the fluctuations in the direction of the force display transient superdiffusive behavior.

description: A novel traveling-wave Zeeman decelerator based on a double-helix coil geometry capable of decelerating paramagnetic molecules with high efficiency is presented. Moving magnetic traps are generated by applying time-dependent currents through the decelerator coils. Paramagnetic molecules in low-field-seeking Zeeman states are confined inside the moving traps which are decelerated to lower forward velocities. As a prototypical example, we demonstrate the deceleration of OH radicals from an initial velocity of 445 m/s down to various final velocities. The experimental results are analyzed and numerically reproduced with the help of trajectory simulations confirming the phase-space stability and efficiency of the deceleration of the molecules in the new device.

description: We constrain the luminosity and redshift dependence of the intrinsic alignment (IA) of a nearly volume-limited sample of luminous red galaxies selected from the fourth public data release of the Kilo-Degree Survey (KiDS-1000). To measure the shapes of the galaxies, we used two complementary algorithms, finding consistent IA measurements for the overlapping galaxy sample. The global significance of IA detection across our two independent luminous red galaxy samples, with our favoured method of shape estimation, is $\sim10.7σ$. We find no significant dependence with redshift of the IA signal in the range $0.2
