description: Thus far, judging the fate of a massive star (either a neutron star (NS) or a black hole) solely by its structure prior to core collapse has been ambiguous. Our work and previous attempts find a non-monotonic variation of successful and failed supernovae with zero-age main-sequence mass, for which no single structural parameter can serve as a good predictive measure. However, we identify two parameters computed from the pre-collapse structure of the progenitor, which in combination allow for a clear separation of exploding and non-exploding cases with only few exceptions (~1-2.5%) in our set of 621 investigated stellar models. One parameter is M4, defining the normalized enclosed mass for a dimensionless entropy per nucleon of s=4, and the other is mu4 = d(m/M_sun)/d(r/1000 km) at s=4, being the normalized mass-derivative at this location. The two parameters mu4 and M4*mu4 can be directly linked to the mass-infall rate, Mdot, of the collapsing star and the electron-type neutrino luminosity of the accreting proto-NS, L_nue ~ M_ns*Mdot, which play a crucial role in the "critical luminosity" concept for the theoretical description of neutrino-driven explosions as runaway phenomenon of the stalled accretion shock. All models were evolved employing the approach of Ugliano et al. for simulating neutrino-driven explosions in spherical symmetry. The neutrino emission of the accretion layer is approximated by a gray transport solver, while the uncertain neutrino emission of the 1.1 M_sun proto-NS core is parametrized by an analytic model. The free parameters connected to the core-boundary prescription are calibrated to reproduce the observables of Supernova 1987A for five different progenitor models.

Digitally Enhanced Interferometry for Precision Metrology
Creators: name: Bandutunga, Chathura
Publisher: name: The Australian National University
Year: 2020

description: In this thesis we employ Digitally Enhanced Interferometric techniques to manage, measure or reject spurious interference. The technique, by using digitally controlled spread-spectrum modulation, manipulates the coherence of an optical source, enabling selective decoding of optical fields based on time-of-flight. Through this thesis, we demonstrate the use of this technique across three scenarios. Firstly, in Part 1, we consider the application to quasi-distributed interferometric sensing in the form of a multi-point interferometric acoustic sensing array. Using Digitally Enhanced Heterodyne interferometry, we demonstrate simultaneous readout from four discrete in-line surfaces using a single measurement optical field. The demonstration characterises the displacement sensitivity of the measurement system, and proceeds to characterise the residual cross-coupling between the independent reflection surfaces. We further demonstrate some of the limitations of the digitally enhanced readout when considering equidistant targets, which has ramifications for multi-point sensing applications such as LIDAR. The second body of work, presented in Part 2, discuses the continued development of the Digitally Enhanced Fibre Frequency Reference. In this instance, we consider the coupling of coherent Rayleigh backscatter into the interferometric measurement. Using Digitally Enhanced Homodyne interferometry, we enable digital manipulation of the coherence length, thereby restricting the coupling of Rayleigh backscatter. The resultant phase noise is both modelled and measured, with good agreement between both. We further implement a method, using a Rubidium stabilised optical frequency comb, to measure the long term drift of the fibre frequency reference. From this we are able to infer the thermal performance of the interferometer isolation chambers, the therm-optic and thermo-elastic expansion of the interferometer. From these insights, we continue on to develop a nominal design for a future fibre frequency reference architecture. The third and final project; Part 3, considers the implementation of a Digitally Enhanced Homodyne interferometric readout to a Sagnac interferometer. The objective of this work was to demonstrate rejection of first order Rayleigh scattering, and was informed by the work on Rayleigh scattering in Part 2. As part of this project, we also demonstrate the first demonstration of a digital interferometric readout using an incoherent source, one which is significantly broader than the digital interferometric spread-spectrum modulation. We also present a first demonstration of sub 1 urad/rt(Hz) noise floor using a digital interferometric readout. Finally, we also surpass the theoretical Rayleigh backscatter induced phase noise floor by over an order of magnitude, demonstrating rejection of first order Rayleigh scattering.
Phase-resolved spectroscopy of low frequency quasi-periodic oscillations in GRS 1915+105

description: X-ray radiation from black hole binary (BHB) systems regularly displays quasi-periodic oscillations (QPOs). In principle, a number of suggested physical mechanisms can reproduce their power spectral properties, thus more powerful diagnostics which preserve phase are required to discern between different models. In this paper, we first find for two Rossi X-ray Timing Explorer (RXTE) observations of the BHB GRS 1915+105 that the QPO has a well defined average waveform. That is, the phase difference and amplitude ratios between the first two harmonics vary tightly around a well defined mean. This enables us to reconstruct QPO waveforms in each energy channel, in order to constrain QPO phase-resolved spectra. We fit these phase resolved spectra across 16 phases with a model including Comptonisation and reflection (Gaussian and smeared edge components) to find strong spectral pivoting and a modulation in the iron line equivalent width. The latter indicates the observed reflection fraction is changing throughout the QPO cycle. This points to a geometric QPO origin, although we note that the data presented here do not entirely rule out an alternative interpretation of variable disc ionisation state. We also see tentative hints of modulations in the iron line centroid and width which, although not statistically significant, could result from a non-azimuthally symmetric QPO mechanism.

Investigating the role of Deleted in Primary Ciliary Dyskinesia (DPCD) protein in Trypanosoma brucei
Creators: name: Ablett, Emily
Publisher: name: Lancaster University
Year: 2023

description: Primary Ciliary Dyskinesia (PCD) is the most common ciliary syndrome in humans, associated with the reduction or loss of function of motile cilia due to inherited mutations. This results in life-altering symptoms spanning multiple organ systems, including airway infections and infertility. Since its discovery in 2004, Deleted in Primary Ciliary Dyskinesia (DPCD) protein has become a novel gene candidate for PCD, with a predicted role in the formation of cilia by ciliogenesis. However, the precise role of this protein in ciliogenesis remains obscure. To provide further insight into the role of this enigmatic protein, the Trypanosoma brucei homologue of DPCD was investigated. Bioinformatics interrogation revealed that DPCD is strongly conserved across ciliated eukaryotes but that a homologue of DPCD is only found in eukaryotes with motile cilia supporting a proposed role in ciliogenesis. However, endogenous tagging of the TbDPCD protein in procyclic T. brucei cells localised the protein to the cell cytoplasm, while RNAi induced ablation of TbDPCD produced no observable effect on cell growth, morphology, motility, or cell cycle progression. This suggests that TbDPCD is not essential for ciliogenesis in T. brucei or potentially has a redundant function. The in-silico interrogation of DPCD protein structure/function using Phyre2 and Alphafold predicted that DPCD has structural similarity to proteins that have chaperone or co-chaperone activity, including small heat-shock proteins. Consequently, the TbDPCD protein was overexpressed and purified from Escherichia coli to determine whether TbDPCD demonstrated chaperone activity under heat stress conditions using a thermal aggregation assay. These experiments could not demonstrate that TbDPCD possesses chaperone activity under heat stress, however, the results indicated that TbDPCD is not stable at elevated temperatures. Overall, the in-silico analysis gives a strong indication of the role of DPCD as a chaperone, however in vivo and biochemical studies did not provide evidence to support this.

Swift reveals a ~5.7 day super-orbital period in the M31 globular cluster X-ray binary XB158

description: The M31 globular cluster X-ray binary XB158 (a.k.a. Bo 158) exhibits intensity dips on a 2.78 hr period in some observations, but not others. The short period suggests a low mass ratio, and an asymmetric, precessing disk due to additional tidal torques from the donor star since the disk crosses the 3:1 resonance. Previous theoretical 3D smoothed particle hydrodynamical modeling suggested a super-orbital disk precession period 29$\pm$1 times the orbital period, i.e. $\sim$81$\pm$3 hr. We conducted a Swift monitoring campaign of 30 observations over ~1 month in order to search for evidence of such a super-orbital period. Fitting the 0.3--10 keV Swift XRT luminosity lightcurve with a sinusoid yielded a period of 5.65+/-0.05 days, and a >5$σ$ improvement in $χ^2$ over the best fit constant intensity model. A Lomb-Scargle periodogram revealed that periods 5.4--5.8 days were detected at a >3$σ$ level, with a peak at 5.6 days. We consider this strong evidence for a 5.65 day super-orbital period, ~70\% longer than the predicted period. The 0.3--10 keV luminosity varied by a factor ~5, consistent with variations seen in long-term monitoring from Chandra. We conclude that other X-ray binaries exhibiting similar long-term behaviour are likely to also be X-ray binaries with low mass ratios and super-orbital periods.

description: Chemically peculiar stars of the upper part of the main sequence show periodical variability in line intensities and continua, modulated by the stellar rotation, which is attributed to the existence of chemical spots on the surface of these stars. The flux variability is caused by the changing redistribution rate of the radiative flux predominantly from the short-wavelength part of the spectra to the long-wavelength part, which is a result of abundance anomalies. We study the nature of the multi-spectral variability of one of the brightest chemically peculiar stars, $θ$ Aur. We predict the flux variability of $θ$ Aur from the emerging intensities calculated for individual surface elements of the star taking into account horizontal variation of chemical composition derived from Doppler abundance maps. The simulated optical variability in the Strömgren photometric system and the ultraviolet flux variability agree well with observations. The IUE flux distribution is reproduced in great detail by our models. The resonance lines of magnesium and possibly also some lines of silicon are relatively weak in the ultraviolet domain, which indicates non-negligible vertical abundance gradients in the atmosphere. We also derive a new period of the star, $P=3.618\,664(10)$ d, from all available photometric and magnetic measurements and show that the observed rotational period is constant over decades. The ultraviolet and visual variability of $θ$ Aur is mostly caused by silicon bound-free absorption and chromium and iron line absorption. These elements redistribute the flux mainly from the far-ultraviolet region to the near-ultraviolet and optical regions in the surface abundance spots. The light variability is modulated by the stellar rotation. The ultraviolet domain is key for understanding the properties of chemically peculiar stars. (abridged)

description: The controllability of a network is a theoretical problem of relevance in a variety of contexts ranging from financial markets to the brain. Until now, network controllability has been characterized only on isolated networks, while the vast majority of complex systems are formed by multilayer networks. Here we build a theoretical framework for the linear controllability of multilayer networks by mapping the problem into a combinatorial matching problem. We found that correlating the external signals in the different layers can significantly reduce the multiplex network robustness to node removal, as it can be seen in conjunction with a hybrid phase transition occurring in interacting Poisson networks. Moreover we observe that multilayer networks can stabilize the fully controllable multiplex network configuration that can be stable also when the full controllability of the single network is not stable.

description: BACKGROUND: To evaluate the occurrence of mutations affecting post-translational modification (PTM) sites in matrisome genes across different tumor types, in light of their genomic and functional contexts and in comparison with the rest of the genome. METHODS: This study spans 9075 tumor samples and 32 tumor types from The Cancer Genome Atlas (TCGA) Pan-Cancer cohort and identifies 151,088 non-silent mutations in the coding regions of the matrisome, of which 1811 affecting known sites of hydroxylation, phosphorylation, N- and O-glycosylation, acetylation, ubiquitylation, sumoylation and methylation PTM. RESULTS: PTM-disruptive mutations (PTMmut) in the matrisome are less frequent than in the rest of the genome, seem independent of cell-of-origin patterns but show dependence on the nature of the matrisome protein affected and the background PTM types it generally harbors. Also, matrisome PTMmut are often found among structural and functional protein regions and in proteins involved in homo- and heterotypic interactions, suggesting potential disruption of matrisome functions. CONCLUSIONS: Though quantitatively minoritarian in the spectrum of matrisome mutations, PTMmut show distinctive features and damaging potential which might concur to deregulated structural, functional, and signaling networks in the tumor microenvironment.
title: Efficacy of Professional Development Models in Dismantling Scientific Misconceptions
Creators: name: Hansen, Tyler
Publisher: name: Utah State University

description: Scientific misconceptions held by educators are both common and well documented. As science education becomes more and more important to students, it is evident that there is a need to not only identify scientific misconceptions held by teachers as a means of bettering the education of students, but also determine effective methods of deconstructing them. Although studies have indicated that professional development can assuage the prevalence of misconceptions held by teachers, there is a dearth in the literature of what makes these professional developments effective. Therefore, this study investigated which models of professional development are most effective in dismantling misconceptions commonly held by teachers. To do this, I collected both qualitative and quantitative data from existing papers regarding misconceptions and professional development. I found that both elementary and secondary teachers benefit in terms of bettering their understanding of misconceptions from both learning science content and learning about teaching in equal amounts. This is surprising because it means that secondary science teachers also need more content training, despite having much more science training than elementary school teachers have. Therefore, the implications of this study are that secondary and elementary school teachers need to be offered more content focused professional developments in order to address their own misconceptions and address misconceptions in their classrooms.

description: In this paper we consider a special kind of three-point functions of HHL type at weak coupling in N=4 SYM theory and analyze its volume dependence. At strong coupling this kind of three-point functions were studied recently by Bajnok, Janik and Wereszczynski [1]. The authors considered some cases of HHL correlator in the su(2) sector and, relying on their explicit results, formulated a conjecture about the form of the volume dependence of the symmetric HHL structure constant to be valid at any coupling up to wrapping corrections. In order to test this hypothesis we considered the HHL correlator in su(2) sector at weak coupling and directly showed that, up to one loop, the finite volume dependence has exactly the form proposed in [1]. Another side of the conjecture suggests that computation of the symmetric structure constant is equivalent to computing the corresponding set of infinite volume form factors, which can be extracted as the coefficients of finite volume expansion. In this sense, extracting appropriate coefficients from our result gives a prediction for the corresponding infinite volume form factors.

description: This paper presents a proof-of-concept method for classifying chemical compounds directly from NMR data without performing structure elucidation. This can help to reduce the time in finding good structure candidates, as in most cases matching must be done by a human engineer, or at the very least a process for matching must be meaningfully interpreted by one. The method identified as suitable for classification is a convolutional neural network (CNN). Other methods, including clustering and image registration, have not been found to be suitable for the task in a comparative analysis. The result shows that deep learning can offer solutions to spectral interpretation problems.

description: Building and productionizing Machine Learning (ML) models is a process of interdependent steps of iterative code updates, including exploratory model design, hyperparameter tuning, ablation experiments, and model training. Industrial-strength ML involves doing this at scale, using many compute resources, and this requires rewriting the training code to account for distribution. The result is that moving from a single host program to a cluster hinders iterative development of the software, as iterative development would require multiple versions of the software to be maintained and kept consistent. In this paper, we introduce the distribution oblivious training function as an abstraction for ML development in Python, whereby developers can reuse the same training function when running a notebook on a laptop or performing scale-out hyperparameter search and distributed training on clusters. Programs written in our framework look like industry-standard ML programs as we factor out dependencies using best-practice programming idioms (such as functions to generate models and data batches). We believe that our approach takes a step towards unifying single-host and distributed ML development.

description: We show that the $(2+1)$-dimensional Dirac-Moshinsky oscillator coupled to an external magnetic field can be treated algebraically with the $SU(1,1)$ group theory and its group basis. We use the $su(1,1)$ irreducible representation theory to find the energy spectrum and the eigenfunctions. Also, with the $su(1,1)$ group basis we construct the relativistic coherent states in a closed form for this problem.

title:  Serialità. Discutendo di identità e differenza
Creators: name: Blatter, Christine
Publisher: name: Roma TrE-Press
Year: 2018

description: Le riflessioni poggiano sul concetto di Young di "genere e serialità" partendo dalla calzante distinzione di Sartre fra serie e gruppi come collettivi sociali (in Critica della ragione dialettica). È un tentativo di andare oltre la concezione pragmatica di Young per delineare un concetto di serie su un livello epistemologico.

Dopo aver esaminato il concetto di serie di Young, che la induce a proporre la serialità come un fatto, l'autrice concettualizza la serialità come un principio specifico, in una prospettiva sessuata, prendendo in considerazione il sistema multiplo di serie di Gilles Deleuze (in "Differenza e ripetizione" e "Logica del senso"), dove si rintraccia la serialità come atto. La nozione di serialità rende possibile pensare un ordine pur evitando la normalizzazione e l'esclusione.

Electromagnetic and neutral-weak response functions of 4He and 12C

description: Ab initio calculations of the quasi-elastic electromagnetic and neutral-weak response functions of 4He and 12C are carried out for the first time. They are based on a realistic approach to nuclear dynamics, in which the strong interactions are described by two- and three-nucleon potentials and the electroweak interactions with external fields include one- and two-body terms. The Green's function Monte Carlo method is used to calculate directly the Laplace transforms of the response functions, and maximum-entropy techniques are employed to invert the resulting imaginary-time correlation functions with associated statistical errors. The theoretical results, confirmed by experiment in the electromagnetic case, show that two-body currents generate excess transverse strength from threshold to the quasi-elastic to the dip region and beyond. These findings challenge the conventional picture of quasi-elastic inclusive scattering as being largely dominated by single-nucleon knockout processes.

description: This paper addresses the problem of single-target tracker performance evaluation. We consider the performance measures, the dataset and the evaluation system to be the most important components of tracker evaluation and propose requirements for each of them. The requirements are the basis of a new evaluation methodology that aims at a simple and easily interpretable tracker comparison. The ranking-based methodology addresses tracker equivalence in terms of statistical significance and practical differences. A fully-annotated dataset with per-frame annotations with several visual attributes is introduced. The diversity of its visual properties is maximized in a novel way by clustering a large number of videos according to their visual attributes. This makes it the most sophistically constructed and annotated dataset to date. A multi-platform evaluation system allowing easy integration of third-party trackers is presented as well. The proposed evaluation methodology was tested on the VOT2014 challenge on the new dataset and 38 trackers, making it the largest benchmark to date. Most of the tested trackers are indeed state-of-the-art since they outperform the standard baselines, resulting in a highly-challenging benchmark. An exhaustive analysis of the dataset from the perspective of tracking difficulty is carried out. To facilitate tracker comparison a new performance visualization technique is proposed.

Common Patterns in the Evolution between the Luminous Neutron Star Low-Mass X-ray Binary Subclasses

description: The X-ray transient XTE J1701-462 was the first source observed to evolve through all known subclasses of low-magnetic-field neutron star low-mass X-ray binaries (NS-LMXBs), as a result of large changes in its mass accretion rate. To investigate to what extent similar evolution is seen in other NS-LMXBs we have performed a detailed study of the color-color and hardness-intensity diagrams (CDs and HIDs) of Cyg X-2, Cir X-1, and GX 13+1 -- three luminous X-ray binaries, containing weakly magnetized neutron stars, known to exhibit strong secular changes in their CD/HID tracks. Using the full set of Rossi X-ray Timing Explorer Proportional Counter Array data collected for the sources over the 16 year duration of the mission, we show that Cyg X-2 and Cir X-1 display CD/HID evolution with close similarities to XTE J1701-462. Although GX 13+1 shows behavior that is in some ways unique, it also exhibits similarities to XTE J1701-462, and we conclude that its overall CD/HID properties strongly indicate that it should be classified as a Z source, rather than as an atoll source. We conjecture that the secular evolution of Cyg X-2, Cir X-1, and GX 13+1 -- illustrated by sequences of CD/HID tracks we construct -- arises from changes in the mass accretion rate. Our results strengthen previous suggestions that within single sources Cyg-like Z source behavior takes place at higher luminosities and mass accretion rates than Sco-like Z behavior, and lend support to the notion that the mass accretion rate is the primary physical parameter distinguishing the various NS-LMXB subclasses.

title:  Inconscio collettivo e pratico-inerte. Per un confronto tra Benjamin e Sartre
Creators: name: Manca, Danilo
Publisher: name: Roma TrE-Press
Year: 2018

description: Nell’articolo si tenta un inedito confronto tra Benjamin e Sartre focalizzandosi sulle comuni critiche immanenti alla prospettiva marxista. In primo luogo, si interpreta la diagnosi del processo di industrializzazione proposta da Benjamin nel suo incompiuto capolavoro, I «passages» di Parigi, come una scoperta del potenziale pratico dell’inerte. In secondo luogo, si confrontano le concezioni del collettivo di Sartre e Benjamin, cercando di dimostrare come entrambi condividano l’idea di un’origine inconscia della prassi rivoluzionaria; infine, si mettono in luce punti di convergenza e di divergenza delle loro interpretazioni della struttura dialettica della storia.

title:  Raccontare e figurarsi: l’inizio di un’avventura e il problema dell’esperienza. Hegel e Sartre a confronto
Creators: name: Rosano, Lucrezia
Publisher: name: Roma TrE-Press
Year: 2018

description: L’obiettivo del mio intervento è di mettere in relazione il concetto di Erfahrung nella Phänomenologie des Geistes con quello di aventure ne La nausée, per mostrare come Hegel e Sartre, con un’operazione fenomenologica simile, facciano emergere un concetto di inerte decisamente controverso, attraverso un’indagine che si insinui nell’intimo della soggettività e nella struttura stessa della temporalità, a partire dall’attività della scrittura. Ho seguito un metodo che facesse dialogare le due prospettive, ed intersecare alcuni punti focali del romanzo della coscienza da un lato, e del romanzo di Antoine Roquentin dall’altro; ho voluto far emergere, geneticamente, il concetto di vita raccontata nella scrittura filosofica e letteraria. Nel capitolo iniziale ho mostrato come si passi dal primissimo rapporto di presenza al mondo, dove l’esperire coincide con l’essere assorbiti dal flusso vivente, all’emergere dell’ «interesse» verso il mondo, che innesca una rivoluzione interna al soggetto. L’esperienza inerte, passiva, passa in altro, dal movimento verso un fine che l’interesse determina, capovolgendo il significato di «tempo». Nel secondo capitolo evidenzio come emergano i concetti di avventura ed esperienza in sé, e come siano profondamente legati alla natura dell’Io, che io definisco – secondo una lettura congiunta degli autori – un «inerte attivo». Nel terzo capitolo, infine, espongo la tesi sartriana sulla letteratura e la ripenso guardando ad Hegel e al modo in cui esiste quale universale oggettivo  e, quindi, cultura.

Extending Single Cell Bioprinting from Femtosecond to Picosecond Laser Pulse Durations

description: Femtosecond laser pulses have been successfully used for film-free single-cell bioprinting, enabling precise and efficient selection and positioning of individual mammalian cells from a complex cell mixture (based on morphology or fluorescence) onto a 2D target substrate or a 3D pre-processed scaffold. In order to evaluate the effects of higher pulse durations on the bioprinting process, we investigated cavitation bubble and jet dynamics in the femto- and picosecond regime. By increasing the laser pulse duration from 600 fs to 14.1 ps, less energy is deposited in the hydrogel for the cavitation bubble expansion, resulting in less kinetic energy for the jet propagation with a slower jet velocity. Under appropriate conditions, single cells can be reliably transferred with a cell survival rate after transfer above 95% through the entire pulse duration range. More cost efficient and compact laser sources with pulse durations in the picosecond range could be used for film-free bioprinting and single-cell transfer.
