description: Within the AMPT Monte Carlo model, hot spots in the initial transverse parton density are shown to lead to harmonic flows which all contribute to dihadron azimuthal correlation. The net back-to-back dihadron correlation after subtraction of harmonic flows still has a double-peak that is independent of the initial geometric triangularity at a fixed impact-parameter and unique to the structure of jet-induced Mach cone and expanding hot spots dragged by radial flow. The longitudinal structure of hot spots also leads to a near-side ridge in dihadron correlation with a large rapidity gap. By successively randomizing the azimuthal angle of the transverse momenta and positions of initial partons, one can isolate the effects of jet-induced medium excitation and expanding hot spots on the dihadron azimuthal correlation with both small and large rapidity gap. The double-peak in the net dihadron correlation is quantitatively different from that in $γ$-hadron that is free of the contributions from harmonic flow and hot spots and caused only by jet-induced Mach cone.

The way we look matters : witnessing. trauma. perspectivism.

description: This began as a film project. We took cameras and queer actors on a filmed/photographed walk in downtown Vancouver to demonstrate that people who look queer receive harsh micro-expressions when they are in public space. The photos were taken in public space and the actors consented to having their images used for this project. This is using the same public photography method used by Hayley Morris Caffiero (professor of photography) in her project Wait Watchers, where she photographed herself in public space and captured the micro-expressions of members of the public as a provocative statement about the type of treatment that fat people experience in public. I wanted to use this photographic method with queer people to demonstrate how queer people are looked at in public, and I wanted to interview the actors afterwards using a photo-elicited interview method where we would review the footage together during a debriefing interview. After I experienced an inter-LGBTQ-community trauma, I decided to incorporate a deeper layer of auto-ethnography into the project and turn this into a story about how we all look at each other imperfectly, including ourselves, including me. It became a process for me to document and move through a phase of existential resentment towards hope. This work is intended as art. It is also intended to be provocative in order to prompt dialogue regarding the importance of the phenomenon of “looking at others” and “being looked at” vis a vis Gender and Power and Hope. I used an interdisciplinary/mixed methods approach: philosophical inquiry, poetic inquiry, narrative inquiry, rhetorical analysis, auto-ethnography, photography, performance, conscientization and photo-elicited journalism. My conclusion is that the way we look does matter, but so does the way we talk about the process of looking, and if we lapse into dogmatic controlling behaviors in response to being looked at harshly, then we perpetuate harm. I also conclude that to some degree hope is an elusive, and mysterious, but nonetheless existentially, poetically, and even academically significant framework from which to perform inquiries about power and gender and witnessing.

description: This article reviews recent research towards a universal light-matter interface. Such an interface is an important prerequisite for long distance quantum communication, entanglement assisted sensing and measurement, as well as for scalable photonic quantum computation. We review the developments in light-matter interfaces based on room temperature atomic vapors interacting with propagating pulses via the Faraday effect. This interaction has long been used as a tool for quantum nondemolition detections of atomic spins via light. It was discovered recently that this type of light-matter interaction can actually be tuned to realize more general dynamics, enabling better performance of the light-matter interface as well as rendering tasks possible, which were before thought to be impractical. This includes the realization of improved entanglement assisted and backaction evading magnetometry approaching the Quantum Cramer-Rao limit, quantum memory for squeezed states of light and the dissipative generation of entanglement. A separate, but related, experiment on entanglement assisted cold atom clock showing the Heisenberg scaling of precision is described. We also review a possible interface between collective atomic spins with nano- or micromechanical oscillators, providing a link between atomic and solid state physics approaches towards quantum information processing.

description: Large prospective cohort studies of rare chronic diseases require thoughtful planning of study designs, especially for biomarker studies when measurements are based on stored tissue or blood specimens. Two-phase designs, including nested case–control and case-cohort sampling designs, provide cost-effective strategies for conducting biomarker evaluation studies.Existing literature for biomarker assessment under two-phase designs largely focuses on simple inverse probability weighting (IPW) estimators. Drawing on recent theoretical development on the maximum likelihood estimators for relative risk parameters in two-phase studies, we propose nonparametric maximum likelihood-based estimators to evaluate the accuracy and predictiveness of a risk prediction biomarker under both types of two-phase designs. In addition, hybrid estimators that combine IPW estimators and maximum likelihood estimation procedure are proposed to improve efficiency and alleviate computational burden. We derive large sample properties of proposed estimators and evaluate their finite sample performance using numerical studies. We illustrate new procedures using a two-phase biomarker study aiming to evaluate the accuracy of a novel biomarker, des-γ-carboxy prothrombin, for early detection of hepatocellular carcinoma. Supplementary materials for this article are available online.

description: Scale-invariant neuronal avalanches have been observed in cell cultures and slices as well as anesthetized and awake brains, suggesting that the brain operates near criticality, i.e. within a narrow margin between avalanche propagation and extinction. In theory, criticality provides many desirable features for the behaving brain, optimizing computational capabilities, information transmission, sensitivity to sensory stimuli and size of memory repertoires. However, a thorough characterization of neuronal avalanches in freely-behaving (FB) animals is still missing, thus raising doubts about their relevance for brain function. To address this issue, we employed chronically implanted multielectrode arrays (MEA) to record avalanches of spikes from the cerebral cortex (V1 and S1) and hippocampus (HP) of 14 rats, as they spontaneously traversed the wake-sleep cycle, explored novel objects or were subjected to anesthesia (AN). We then modeled spike avalanches to evaluate the impact of sparse MEA sampling on their statistics. We found that the size distribution of spike avalanches are well fit by lognormal distributions in FB animals, and by truncated power laws in the AN group. The FB data are also characterized by multiple key features compatible with criticality in the temporal domain, such as 1/f spectra and long-term correlations as measured by detrended fluctuation analysis. These signatures are very stable across waking, slow-wave sleep and rapid-eye-movement sleep, but collapse during anesthesia. Likewise, waiting time distributions obey a single scaling function during all natural behavioral states, but not during anesthesia. Results are equivalent for neuronal ensembles recorded from V1, S1 and HP. Altogether, the data provide a comprehensive link between behavior and brain criticality, revealing a unique scale-invariant regime of spike avalanches across all major behaviors.

Following plating of bacteria and unseeded media on either side of the plate, a population of nematodes was placed along the center of a 10 cm 2% NGM plate and allowed to migrate for the duration of the assay. A chemotaxis index (CI) was then calculated after counting the number of nematodes in each region as: CI = (# worms in bacteria - # worms in control) / (# worms in bacteria + # worms in control). A positive CI indicates attraction to the bacteria, a negative CI indicates repulsion, and a CI near zero indicates a neutral response. b-e.

description: This paper analyzed the physicochemical properties, functional properties and proximate composition of cactus tuna flour and cactus napolite flours prepared from cactus pear fruit–vegetable parts. Immature cactus fruit and leaf-vegetable parts were dried at 60°C, 70°C and 80°C. The cactus fruit ‘tuna’ and napolite parts of plants were dried and thoroughly milled into flour. The flours were analyzed for physicochemical properties, functional properties and proximate composition. The analyses showed no significant differences in crude protein, total lipid, crude fiber and total ash content in the flours. The results also revealed that napolite flour has higher moisture content and total solid 6.85% and 18.50%, respectively while tuna flour had higher ash (26.20%) and crude fiber (22.11%). The PH value of fresh fruit-vegetable was found to be between 6.20 – 6.65 while the flours PH value lies between 5.27 – 5.80. Functional properties for napolite flour showed water and oil holding capacity of 14.12 (60oC), 8.35 (70oC), 6.42 (80oC), and 2.02 (60oC), 2.01 (70oC), 2.02 (80oC) respectively. On the other hand, water and oil holding capacity of tuna flour were 16.24 (60oC), 10.21 (70oC), 7.12 (80oC), and 3.01 (60oC), 3.02 (70oC), 3.01 (80oC) respectively. At 60oC to 80oC a reduction of water holding capacity (54.3%) was observed in napolite flour, while 56.12% observed in tuna flour. The cladodes flours prepared at 60°C presented a higher quality regarding their nutritional and functional properties. Similarly, cactus fruit-vegetable flour had higher potential of water holding capacity and others functional properties. The physicochemical properties and functional properties of Cactus fruit – vegetable flour have good potential and nutritional value to service as flour.

An alternative to the plasma emission model: Particle-In-Cell, self-consistent electromagnetic wave emission simulations of solar type III radio bursts

description: 1.5D PIC, relativistic, fully electromagnetic (EM) simulations are used to model EM wave emission generation in the context of solar type III radio bursts. The model studies generation of EM waves by a super-thermal, hot beam of electrons injected into a plasma thread that contains uniform longitudinal magnetic field and a parabolic density gradient. In effect, a single magnetic line connecting Sun to earth is considered, for which several cases are studied. (i) We find that the physical system without a beam is stable and only low amplitude level EM drift waves (noise) are excited. (ii) The beam injection direction is controlled by setting either longitudinal or oblique electron initial drift speed, i.e. by setting the beam pitch angle. In the case of zero pitch angle, the beam excites only electrostatic, standing waves, oscillating at plasma frequency, in the beam injection spatial location, and only low level EM drift wave noise is also generated. (iii) In the case of oblique beam pitch angles, again electrostatic waves with same properties are excited. However, now the beam also generates EM waves with the properties commensurate to type III radio bursts. The latter is evidenced by the wavelet analysis of transverse electric field component, which shows that as the beam moves to the regions of lower density, frequency of the EM waves drops accordingly. (iv) When the density gradient is removed, electron beam with an oblique pitch angle still generates the EM radiation. However, in the latter case no frequency decrease is seen. Within the limitations of the model, the study presents the first attempt to produce simulated dynamical spectrum of type III radio bursts in fully kinetic plasma model. The latter is based on 1.5D non-zero pitch angle (non-gyrotropic) electron beam, that is an alternative to the plasma emission classical mechanism.

description: Il presente lavoro di diploma analizza alcune possibilità per insegnare la storia ambientale all’interno del programma del primo biennio liceale. Si è partiti dal costruire delle unità didattiche in cui la prospettiva ambientale fosse sempre presente e fungesse da grande cornice: si è pensato di non sacrificare una parte del programma, ma ci si è orientati sull’usare i risultati acquisiti dagli studi più recenti sul tema per spiegare alcune grandi cesure, cercando comunque di fare comprendere agli studenti che l’uomo è sempre inserito e in rapporto con l’ambiente. La sperimentazione ha coinvolto allievi del primo biennio liceale, nello specifico cinque classi prime e una seconda, per un totale di 120 tra studenti e studentesse.

The algorithm proceeds via recursion in m seeded by the well-known box integrals in four dimensions. As a simple application of this method we write down the symbol of a three-mass hexagon integral in six dimensions.

description: Primula amethystina subsp. argutidens (Franchet) W. W. Smith & H. R. Fletcher (1942) is a blooming plant of the family Primulaceae. Here, we sequenced, assembled, and annotated the complete chloroplast (cp) genome of P. amethystina subsp. argutidens. The cp genome of P. amethystina subsp. argutidens is 151,560 bp in length with a GC content of 37%. The assembled genome has a typical quadripartite structure, containing a large single-copy (LSC) region of 83,516 bp, a small single-copy (SSC) region of 17,692 bp, and a pair of inverted repeat (IR) regions of 25,176 bp. The cp genome contains 115 unique genes, including 81 protein-coding genes, four rRNA genes, and 30 tRNA genes. Phylogenetic analysis showed that P. amethystina subsp. argutidens was closely related to P. amethystina.

description: We report studies of pinning mode resonances of magnetic field induced bilayer Wigner crystals of bilayer hole samples with negligible interlayer tunneling and different interlayer separations d, in states with varying layer densities, including unequal layer densities. With unequal layer densities, samples with large d relative to the in-plane carrier-carrier spacing a, two pinning resonances are present, one for each layer. For small d/a samples, a single resonance is observed even with significant density imbalance. These samples, at balance, were shown to exhibit an enhanced pinning mode frequency [Zhihai Wang et al., Phys. Rev. Lett. 136804 (2007)], which was ascribed to a one-component, pseudospin ferromagnetic Wigner solid. The evolution of the resonance frequency and line width indicates the quantum interlayer coherence survives at moderate density imbalance, but disappears when imbalance is sufficiently large.
Violence against Social Leaders and Human Rights Defenders in the context of the 2016 Peace Accords in Colombia
Creators: name: Peñuela Gallo, Natalia
Publisher: name: University of British Columbia
Year: 2020

description: This thesis focuses on the violence against social leaders and human rights defenders (SLs & HRDs) in the context of the post-agreement starting with the first release of the Peace Accords (August 2016) until its first phase of implementation (June 2017) in Colombia. The research questions examine the relationship between the Peace Accords and the wave of assassinations of SLs & HRDs, and the extent to which intersectional elements of social class, gender, sexuality, race, and perceived political ideology play a role. A qualitative, field-based inquiry was conducted in Colombia for a period of three months through twenty-one semi-structured interviews, and document analysis of statistical and empirical data. Using four recurring themes of power of language, production of knowledge, labels and representation- drawing from Foucault’s understanding of power and knowledge creation, in addition to intersectionality, this thesis emphasizes that the populations who continue to be the recipients of multiple interconnected and intersecting social violence(s), are in fact, the ones who are crucial for the construction of peace and post-agreement period. This thesis argues that SLs & HRDs who are most likely to get targeted or killed are those who oppose the forces of licit and illicit capital, and those who are perceived to be subversive to the neoliberal system. They are Indigenous, Afro-descendant, Campesinxs individuals with diverse gender identities, sexual orientations, and allies, who have created ways to survive extraordinary worlds of violence, while demanding collective reparation and protections for their lives and territories. These individuals represent constellations of peace(s) with unimaginable strength, and full of wisdom about resilience. Colombia’s Peace Accords reflect the experiences and failures of past peace agreements, peace negotiations, demobilization processes and post-agreement scenarios, and include attention to plurality, difference, security, and human rights protection. Although the signing of the Peace Accords is a prominent step forward, Colombia continues to experience the contradictory contexts of ongoing conflict and historical transformation as the dynamics of war change. This analysis shows the complexity and urgency of the situation in Colombia, to also call attention towards this violence in other spaces worldwide.

description: Diversity in African Languages contains a selection of revised papers from the 46th Annual Conference on African Linguistics, held at the University of Oregon. Most chapters focus on single languages, addressing diverse aspects of their phonology, morphology, semantics, syntax, information structure, or historical development. These chapters represent nine different genera: Mande, Gur, Kwa, Edoid, Bantu, Nilotic, Gumuzic, Cushitic, and Omotic. Other chapters investigate a mix of languages and families, moving from typological issues to sociolinguistic and inter-ethnic factors that affect language and accent switching. Some chapters are primarily descriptive, while others push forward the theoretical understanding of tone, semantic problems, discourse related structures, and other linguistic systems. The papers on Bantu languages reflect something of the internal richness and continued fascination of the family for linguists, as well as maturation of research on the family. The distribution of other papers highlights the need for intensified research into all the language families of Africa, including basic documentation, in order to comprehend linguistic diversities and convergences across the continent. In this regard, the chapter on Daats’íin (Gumuzic) stands out as the first-ever published article on this hitherto unknown and endangered language found in the Ethiopian-Sudanese border lands.

A Grammar of Rapa Nui
Creators: name: Kieviet, Paulus
Publisher: name: Language Science Press
Year: 2017

description: This book is a comprehensive description of the grammar of Rapa Nui, the Polynesian language spoken on Easter Island.
After an introductory chapter, the grammar deals with phonology, word classes, the noun phrase, possession, the verb phrase, verbal and nonverbal clauses, mood and negation, and clause combinations.
The phonology of Rapa Nui reveals certain issues of typological interest, such as the existence of strict conditions on the phonological shape of words, word-final devoicing, and reduplication patterns motivated by metrical constraints.
For Polynesian languages, the distinction between nouns and verbs in the lexicon has often been denied; in this grammar it is argued that this distinction is needed for Rapa Nui.
Rapa Nui has sometimes been characterised as an ergative language; this grammar shows that it is unambiguously accusative. Subject and object marking depend on an interplay of syntactic, semantic and pragmatic factors.
Other distinctive features of the language include the existence of a ‘neutral’ aspect marker, a serial verb construction, the emergence of copula verbs, a possessive-relative construction, and a tendency to maximise the use of the nominal domain.
Rapa Nui’s relationship to the other Polynesian languages is a recurring theme in this grammar; the relationship to Tahitian (which has profoundly influenced Rapa Nui) especially deserves attention.
The grammar is supplemented with a number of interlinear texts, two maps and a subject index.

description: It is shown that the Pioneer anomaly is a natural consequence of variable speed of light cosmological models wherein the speed of light is assumed to be a power-law function of the scale factor (or cosmic time). In other words, the Pioneer anomaly can be regarded as a non-gravitational effect of the continuously decreasing speed of light which indicates itself as an anomalous light propagation time delay in local frames. This time delay is accordingly interpreted as an additional Doppler blue shift.

description: This study was aimed at characterizing natural hone produced in different lowlands of Eastern Hararge, Ethiopia. Standard methods were employed to study the physicochemical properties and trace metal contents of the selected samples. The results showed that the content of moisture, electrical conductivity, pH, free acid value and total acid value were ranged from 9.07-19.32%, 0.32-0.75 mS/cm, 3.48-4.25, 25.83-64.17 meq/kg and 28.25-66.5 meq/kg respectively. These results showed similarity with national and international reports. The contents of Fe, Zn, Cu, Co, Cd, Pb, Mn, Ni and Cr were determined using Flame Atomic Absorption Spectrophotometry. As to the determination results, the concentrations of the elements were found to be ND - 6.04 mg/kg, ND - 1.01 mg/kg, ND - 0.44 mg/kg, ND - 0.45 mg/kg, ND - 0.28 mg/kg, ND - 0.25 mg/kg, ND - 0.15 mg/kg, ND and ND respectively. These results vividly revealed the amounts of metals in safety baseline levels for human consumption.

Azionamento elettrico per un nuovo concetto di cuore artificiale pulsantile senza valvole
Creators: name: Botto, Andrea
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2020

description: L’arresto cardiaco è uno dei maggiori problemi del cuore con un alto tasso di mortalità associato. Si parla di una prevalenza di 22 milioni nel mondo, 150’000 in Svizzera e ci si aspetta che questo dato raddoppi entro il 2040. In casi estremi risulta necessario un trapianto ma sono indispensabili sia donatori che una perfetta compatibilità tra donatore e paziente. Un cuore artificiale pulsantile senza valvole risulta fondamentale per sopperire alla mancanza di donatori. Al fine di rendere possibile il suo funzionamento è necessario lo studio e la realizzazione di un sistema di controllo. Il nuovo cuore artificiale è formato da due palette vincolate tra loro che, grazie alla loro rotazione, simulano gli atri e i ventricoli, creando un flusso pulsantile di sangue. In questo progetto sono stati studiati e ricercati attuatore, driver e sensori al fine di realizzare un sistema basato sul microcontrollore ST Cortex M4. Si conclude che il prototipo realizzato rientra nelle specifiche ed integra le funzioni sia per pilotare il motore collegato esternamente al cuore artificiale che per leggere il flusso e la pressione del sangue nel sistema circolatorio ed informare l’utente tramite terminale. Il sistema può essere integrato in un banco di test e successivamente impiantato nel corpo umano previa miniaturizzazione e impermeabilizzazione.

description: In this paper we calculate the contributions to the branching ratio of $B_s \to γγ$ from the charged Pseudo-Goldstone bosons appeared in one generation Technicolor model. We find that the theoretical values of the branching ratio, $BR(B_s\toγγ)$, including the contributions of PGBs, $P^\pm$ and $P^{\pm}_8$, are much different from the $SM$ prediction. The new physics effects can be enhance 2-3 levels to $SM$ result. It is shown that the decay $B_s\to γγ$ can give the test the new physics signals from the technicolor model.

description: The study was conducted to assess the impact of agricultural and industrial wastes on the distribution and relative abundance of fish along the upper Awash River Basin. Fishes were collected using electrofishing apparatus from three sampling sites along the river representing different levels of anthropogenic impacts on the river. A total of 1912 fish belonging to five species were collected from all sampling sites. Nearly 73.43% of the fish were collected from the pool as compared with that of rifle habitat. Fish abundance varied significantly (p<0.05) between the sampling sites. Generally, diversity of fish and abundance declined drastically from the less impacted site towards the downstream sites S2 and S3 indicating the impact of agricultural and industrial effluents on the fish fauna of the river Awash.

Palestra: scuola di vita. Le potenzialità dell'educazione fisica nello sviluppo del futuro cittadino
Creators: name: Canali, Riccardo

Year: 2023

description: Secondo le nuove indicazioni formative, la scuola deve adottare una didattica per competenze, integrando aspetti disciplinari e soprattutto trasversali. L’obiettivo è che gli allievi acquisiscano competenze – l’insieme di saperi, abilità e atteggiamenti – all’interno dell’ambiente scolastico poi trasferibili e applicabili in tutti i contesti della vita (Capitolo 1). Il progetto “Competenze democratiche in ed. fisica”, rivolto a 35 studenti del Io e IIIo anno della scuola media di Agno, dimostra come sia possibile integrare l’area motricità al contesto di formazione generale “Vivere insieme ed educazione alla cittadinanza”. Attraverso 5 lezioni con attività pratiche con partner e/o avversario, ho stimolato collaborazione, comunicazione, rispetto, empatia e metariflessione. I questionari sottoposti pre- e post-progetto e l’analisi dei loro risultati hanno dimostrato le potenzialità dell’educazione fisica. Infatti, confrontarsi con questi concetti astratti all’interno di attività ludiche, ha permesso agli studenti di interiorizzarli e orientare il proprio agire verso una cultura democratica (Capitolo 2). Tutti i docenti, anche con proposte interdisciplinari, dovrebbero orientare la propria programmazione verso la formazione non solo di studenti coscienziosi ma anche di futuri cittadini, civili e attivi nella società in cui vivranno (Capitolo 3). Risposte “Totalmente d’accordo” e “Abbastanza d’accordo” alla d.10 relativa alla comunicazione. L’istogramma mostra come le attitudini verso una comunicazione efficace e non violenta siano migliorate post-progetto: viene data importanza sia all’espressione sia all’ascolto, si parla meno sopra gli altri e si coinvolgono tutti gli interlocutori.

Precision calculation of blackbody radiation shifts for optical frequency metrology

description: We show that three group IIIB divalent ions, B+, Al+, and In+, have anomalously small blackbody radiation (BBR) shifts of the ns^2 1S0 - nsnp 3P0 clock transitions. The fractional BBR shifts for these ions are at least 10 times smaller than those of any other present or proposed optical frequency standards at the same temperature, and are less than 0.3% of the Sr clock shift. We have developed a hybrid configuration interaction + coupled-cluster method that provides accurate treatment of correlation corrections in such ions, considers all relevant states in the same systematic way, and yields a rigorous upper bound on the uncertainty of the final results. We reduce the BBR contribution to the fractional frequency uncertainty of the Al+ clock to 4 \times 10^{-19} at T=300K. We also reduce the uncertainties due to this effect at room temperature to 10^{-18} level for B+ and In+ to facilitate further development of these systems for metrology and quantum sensing. These uncertainties approach recent estimates of the feasible precision of currently proposed optical atomic clocks.
