description: The INhibitor of Growth family (INGs 1-5) is part of lysine acetyltransferase and lysine deacetylase complexes. They are epigenetic readers that recruit these complexes to the H3K4Me3 mark of active transcription.. Several studies have implicated ING5 in stem cell maintenance in adult and cancer stem cells, cell cycle regulation, and DNA damage response pathways. Here, we investigate the roles of ING5 in two different systems: primary mouse embryonic fibroblasts (MEFs) derived from our Ing5-KO murine model and Brain Tumor Initiating Cells (BTIC cancer stem cells) derived from glioblastoma patients. We show that Ing5-KO MEFs have defects in the cell cycle, with cells accumulating in the G2/M phase of the cell cycle, and carry a higher DNA damage load than their WT counterparts. In addition, after exposure to oxidative stress Ing5-KO cells frequently have abnormal nuclei, defective mitosis and express increased levels of the p21 cyclin-dependent kinase inhibitor compared to WT. RNA-seq analysis of Ing5-KO MEFs revealed significant downregulation of the HOXA family of transcription factors and other transcription factors involved in development such as FOXD1, SOX5 and two transcription factors of the GATA family, indicating that ING5 is part of a network for the regulation of developmental transcription factors. ING5 was also detected on the promoters of SOX4 and GATA6 in primary human fibroblasts, established human embryonic kidney (HEK293) cells and a glioma stem cell.

On random access control for multipacket reception S-ALOHA in wireless cellular networks
Creators: name: Seo, Jun-Bae
Publisher: name: University of British Columbia
Year: 2012

description: Studies on slotted ALOHA (S-ALOHA) systems have a long research history and been quite mature in the literature. However, this thesis revisits S-ALOHA systems by considering multipacket reception (MPR) channels, because previous studies are no longer applicable to MPR capable S-ALOHA systems due to the new random access channels (RACHs) of contemporary wireless cellular network standards. Particularly, it is dubious to apply the contention resolution algorithms (CRAs) developed so far for S-ALOHA systems to MPR S-ALOHA systems without any modification. Accordingly, this thesis proposes cross-layer CRAs and investigates the performance of some existing CRAs in MPR S-ALOHA systems in order to maximize the system throughput in tandem with stabilizing the system. Cross-layer CRAs proposed are based on estimating the system backlog information, which is obtained from multiple access interference (MAI) in the physical layer of Code Division Multiple Access (CDMA) MPR channel. Then, the proposed algorithms broadcast a retransmission probability in order to maximize the system throughput. The performance and the stability of the proposed algorithms are examined under various radio channel conditions. Compared to the proposed algorithms based on the system backlog information, the existing uniform backoff (UB) and exponential backoff (EB) algorithms are blind to such information. In order to understand the behaviour of these algorithms in MPR S-ALOHA, they are investigated with respect to various performance metrics and stability conditions. Additionally, the power ramping (PR) scheme is examined together with UB algorithm, in order to see whether it shows power capture effect in MPR S-ALOHA systems during a random access. Furthermore, the queueing performance of the MPR S-ALOHA system is investigated with an uplink traffic of the Markov Modulated Bernoulli Process (MMBP), when UB algorithm with retry limit is employed. It is also examined whether MPR S-ALOHA would be feasible for reserving a channel for a delay sensitive traffic. As a practical example, Semi-Persistent Scheduling (SPS) with initial random access in Long Term Evolution (LTE) is examined over MPR S-ALOHA, in which a traffic channel reservation for Voice-over IP (VoIP) is made at the onset of the ON period by a random access.

description: Underrepresentation of female-sexed participants in research has been widely attributed to challenges in tracking the menstrual cycle (MC). Different methodologies have been employed to overcome barriers of high costs and burden but may have resulted in reduced MC research quality. Recently, a combination of evidence-based methods has been shown to detect MC phases in lab settings. A gap, however, remains in field-based settings where a need exists for reliable MC tracking methods. New technologies for MC tracking could help reduce this gap, but many lack incorporation of scientific methods. This warrants development of accessible and evidence-informed MC tracking methods for field-based studies and to describe data provided by MC technologies. The purpose of this thesis was to 1) examine the use of salivary and urinary methods in MC phase detection, 2) assess the performance of a modified, three-step MC tracking method in MC classification, and 3) pilot test this method to describe data employing a MC technology. Naturally cycling female-sexed participants were recruited (n = 44) to complete calendar counting, urine ovulation tests, and salivary hormone tests during their estimated mid-luteal phase while using this technology. It was observed that salivary and urinary methods could be used for MC phase detection and this approach informed the study methodology. The modified, three-step method yielded a sensitivity of 64.7% and specificity of 90.9% in classifying individuals as high and low hormone. Cycle length (p = 0.0007) and salivary progesterone (p < 0.0001) were significantly different between hormone groups. Based on the results, progesterone may be a meaningful MC phase identifier (OR 1.98, 95% CI 1.24 – 3.17, p < 0.0001). The modified, three-step method was used as a tool to assess agreement with predefined menstrual phases in this technology which showed promise as an assessment tool. These results may contribute to future MC research by reducing burden and accessibility barriers through the development of field-based, evidence-informed practices.

description: In this paper we continue our investigation on the high storage regime of a neural network with Gaussian patterns. Through an exact mapping between its partition function and one of a bipartite spin glass (whose parties consist of Ising and Gaussian spins respectively), we give a complete control of the whole annealed region. The strategy explored is based on an interpolation between the bipartite system and two independent spin glasses built respectively by dichotomic and Gaussian spins: Critical line, behavior of the principal thermodynamic observables and their fluctuations as well as overlap fluctuations are obtained and discussed. Then, we move further, extending such an equivalence beyond the critical line, to explore the broken ergodicity phase under the assumption of replica symmetry and we show that the quenched free energy of this (analogical) Hopfield model can be described as a linear combination of the two quenched spin-glass free energies even in the replica symmetric framework.

description: What should be the quasinormal modes associated with a spacetime that contains a naked singularity instead of a black hole? In the present work we address this problem by studying the scattering of scalar fields on a curved background described by a Reissner-Nordström spacetime with $|q| > m$. We show that there is a qualitative difference between cases with $1 < q^2/m^2 \lesssim 9/8$ and cases with $q^2/m^2 \gtrsim 9/8$. We discuss the necessary conditions for the well-posedness of the problem, and present results for the low damped modes in the low $l$ and large $l$ limit. We also consider the asymptotically highly damped quasinormal modes. We present strong evidence that such modes are absent in the case of a naked Reissner-Nordström singularity, corroborating recent conjectures relating them to classical and quantum properties of horizons.

description: Dans un contexte où l’enseignement en français, langue seconde, prédomine au Togo méridional, cette étude explore, à travers le prisme de la théorie des représentations sociales de Moscovici et d’Abric, la perception et la représentation de la langue éwé par ses locuteurs. L’objectif est d’examiner les implications de cette dynamique sur l’identité culturelle et linguistique, ainsi que sur les potentielles réformes linguistiques. Adoptant une approche méthodologique mixte, 83 participants ont été sollicités via des questionnaires et entretiens, générant des données quantitatives et qualitatives. L'analyse s’est axée sur l’impact de l’éwé sur l’identité des locuteurs, ses contributions aux défis éducatifs, et son rôle dans les futures réformes linguistiques. Les données ont été analysées en utilisant une échelle de Likert à 5 points et le logiciel SPSS version 28. Les résultats indiquent une forte valorisation de l’éwé dans la construction de l’identité individuelle et communautaire, contribuant à l’unité et la fierté. Toutefois, son intégration limitée dans les sphères formelles, notamment en politique, restreint la participation de certains groupes sociaux, particulièrement les femmes et les moins éduqués. L’étude révèle aussi un déficit de terminologie scientifique en éwé et des obstacles professionnels pour les individus formés dans cette langue. Face à ces enjeux, les participants préconisent une politique linguistique plus inclusive et plurilingue, qui permettrait de surmonter les barrières linguistiques et d’améliorer la communication intercommunautaire. L’étude souligne la nécessité urgente d’adresser les problèmes d’instrumentalisation de l’éwé pour favoriser une éducation plus inclusive. Malgré la valorisation de l’éwé par ses locuteurs, des défis subsistent concernant sa représentation et son intégration dans les secteurs éducatifs et politiques, nécessitant des réformes linguistiques attentives et inclusives.

description: The data processing inequality (DPI) is a fundamental feature of information theory. Informally it states that you cannot increase the information content of a quantum system by acting on it with a local physical operation. When the smooth min-entropy is used as the relevant information measure, then the DPI follows immediately from the definition of the entropy. The DPI for the von Neumann entropy is then obtained by specializing the DPI for the smooth min-entropy by using the quantum asymptotic equipartition property (QAEP). We provide a new, simplified proof of the QAEP and therefore obtain a self-contained proof of the DPI for the von Neumann entropy.

description: This paper presents a comparative study of General Anti-Avoidance Rules (GAAR) in India and Australia. GAAR provisions are designed to prevent individuals and corporations from using tax laws to avoid paying taxes. The paper explores the statutory provisions and judicial decisions of both countries to understand the nuances of the principle of anti-avoidance. While the objectives of GAAR provisions in both countries are similar, the scope and application of the provisions differ significantly. The Indian provisions apply to all arrangements, while the Australian provisions only apply to schemes. Additionally, the Indian GAAR provisions require the arrangement to lack commercial substance, while the Australian provisions do not require such a test. The paper also examines the judicial interpretations of GAAR provisions in both countries. The Indian courts have adopted a more restrictive approach, while the Australian courts have adopted a more liberal approach. The paper concludes that a case-by-case approach is necessary in the application of GAAR provisions, taking into account the specific facts and circumstances of each situation.

description: Generalizing the quantifiers used to classify correlations in bipartite systems, we define genuine total, quantum, and classical correlations in multipartite systems. The measure we give is based on the use of relative entropy to quantify the "distance" between two density matrices. Moreover, we show that, for pure states of three qubits, both quantum and classical bipartite correlations obey a ladder ordering law fixed by two-body mutual informations, or, equivalently, by one-qubit entropies.

description: This thesis offer a new look at the inferential reading of visual codes through the concept of reconciled narrative-visual space, which has as its primary objective the narrative, aesthetic, pedagogical and compositional analysis of the first wordless picture book of the first part of the Cervantes novel, Don Quijote of La Mancha (i.e., DQ 1605), which, associated with nine art movements, aims to be a compositional and pedagogical guide for the teaching of art and literature. This project proposes to use a methodological framework based on the study of Cervantes' novel through an intertextual perspective between the history of art and literature and the narrative-visual adaptation based on reverse ekphrasis and the reconciled narrative-visual space model. It identifies different layers of meaning established in the composition, the sequence of images, and the literary devices implicit in the image. Thus, these components help develop the pedagogical and aesthetic resources that encompass the first wordless book adaptation of this novel.

description: On-going Higgs searches in the light mass window are of vital importance for testing the Higgs mechanism and probing new physics beyond the standard model (SM). The latest ATLAS and CMS searches for the SM Higgs boson at the LHC (7TeV) found some intriguing excesses of events in the γγ/VV^* channels (V=Z,W) around the mass-range of 124-126 GeV. We explore a possible explanation of the γγand VV^* signals from the light CP-odd Higgs A^0 or CP-even Higgs h^0 from the general two-Higgs-doublet model with fourth-family fermions. We demonstrate that by including invisible decays of the Higgs boson A^0 or h^0 to fourth-family neutrinos, the predicted γγand VV^* signals can explain the observed new signatures at the LHC, and will be further probed by the forthcoming LHC runs in 2012.

description: Human lives involve remarkable forms of social organization. Not only do they work together towards common goals, but they also divide themselves into mutually exclusive, and sometimes opposing, groups. A comprehensive theory of social phenomena should help us understand and appreciate the complexity and diversity of the social world. Towards building a comprehensive theory of social phenomena, this thesis argues that the key to a theory’s success lies in an in-depth investigation of two closely connected but ultimately separable concepts: “reasons” and “norms.” This thesis attempts to show that our social world can be satisfactorily explained in terms of “motivating reasons” and “norms,” neither of which requires any prior understanding of the nature of human collectivity. In contrast, collectivists, such as Margaret Gilbert and John Searle, describe our social world in terms of collective, group-centric concepts such as joint commitment, shared intentionality and we-reasoning. Taking joint commitment as an example, this thesis defends the singularist approach against collectivism by developing a novel singularist framework, the MR-N (Motivating Reason-Norm) framework and show how the MR-N framework can be used fully describe any collective concept and, in particular, the concept of joint commitment. As a result, the diverse range of social phenomena that can be described using the concept of joint commitment can also be described in terms of the MR-N framework. This thesis then briefly considers a popular singularist theory proposed by Michael Bratman, who seeks to combine a theory of planning together with a theory of law proposed by H. L. A. Hart and compares Bratman’s singularist theory to the singularist MR-N framework.

description: State-of-the-art predictions for the Higgs-boson production cross section via gluon fusion and for all relevant Higgs-boson decay channels are presented in the presence of a fourth Standard-Model-like fermion generation. The qualitative features of the most important differences to the genuine Standard Model are pointed out, and the use of the available tools for the predictions is described. For a generic mass scale of 400-600 GeV in the fourth generation explicit numerical results for the cross section and decay widths are presented, revealing extremely large electroweak radiative corrections, e.g., to the cross section and the Higgs decay into WW or ZZ pairs, where they amount to about -50% or more. This signals the onset of a non-perturbative regime due to the large Yukawa couplings in the fourth generation. An estimate of the respective large theoretical uncertainties is presented as well.

description: Magnetite nanoparticles (NPs) have shown promising potential for different applications including drug delivery, magnetic resonance imaging, environmental remediation, and catalysis. However, the main challenge limiting the magnetite NP applicability is its tendency to aggregate. As a result, a lot of research has been conducted on magnetite NP stabilization to improve their suitability for different applications. This thesis goal was to investigate the incorporation of magnetite NPs into microgels as a stabilization technique of the magnetite NPs and evaluate the magnetite NP-microgel hybrid system for two specific applications I) magnetic reservoir monitoring, and II) Lead removal from water. Microgels based on poly(N-isopropyl acrylamide) (PNIPAM) containing different mole ratios of methacrylic acid (MAA) were designed as templates for the in-situ synthesis and incorporation of magnetite NPs. Subsequently, microgel colloidal stability regarding NaCl concentration and temperature was studied to assess their applicability for subsurface applications. It was shown that microgels with a PNIPAM/MAA mole ratio of 40/60 remained stable at elevated temperatures (80 °C) and salinity (up to 10 wt% NaCl) which makes them suitable for subsurface applications. Additionally, the core-flooding experiment indicated that the magnetite NPs-microgel is magnetically detectable and does not have permanent retention in the porous medium. The obtained results show that magnetite NP-PNIPAM-co-MAA microgel has great potential as a magnetic contrast agent for reservoir monitoring. Magnetite NPs incorporated into the PNIPAM microgel were used as adsorbent for Pb2+ removal from water. The designed adsorbent was efficient in Pb2+ removal from water with a maximum capacity of 46 mg Pb2+/g. The results indicated that using microgels as carriers for magnetite NPs is an effective method for adsorption applications due to the porous structure of the microgels which facilitates high mass exchange between magnetite NPs and aqueous medium. In conclusion, results obtained from this study show that the magnetite NP-microgel hybrid system as a multifunctional material provides design flexibility to create materials for applications in various fields including but not limited to lead uptake from water and magnetic reservoir monitoring.

description: Instructors teaching an Indigenous education course face the challenges of shifting students’ understanding and inviting them into the work of decolonizing education. Indigenous instructors take on the embodied and emotional work of highlighting diverse representations of Indigenous peoples, histories, and perspectives in scholarship in order to make this learning meaningful to students. Bringing such views to education students, who are mostly non-Indigenous, is no easy task. In this study, we examine instructor experiences of difficult teaching within a mandatory Indigenous education course in Canada. We adopt a ‘poetics of anti-racism’ to represent and explore the moments of difficult teaching that are indicated by what is said, and unsaid, by the Indigenous instructors we interviewed. We argue that poetic approaches are powerful in articulating the complexity of Indigenous instructors’ experiences, as well as inspiring moments of transformation in education.
Plant screening for tyrosine/phenylalanine ammonia lyase and biochemical characterisation, purification and cloning of the tyrosine/phenylalanine ammonia lyase enzyme from Trichosporon cutaneum
Creators: name: Goldson, Andrea Michelle

description: Phenylalanine ammonia lyase (PAL, EC 4.3.1.24) catalyzes the conversion of phenylalanine (Phe) to trans cinnamic acid and, in some instances tyrosine (Tyr) to para hydroxycinnamic acid (pHCA). The specificity of PAL for Phe relative to Tyr varies by over 10⁶ between biological sources. An understanding of the basis for this astounding range of substrate preference is required to rationally engineer a highly efficient Tyr-specific enzyme for use in synthesizing pHCA for health, pharmaceutical and flavour applications. Of the plant seedlings screened for PAL activity, Triticum aestivum displayed the highest level of activity with both substrates. A unique 103 kDa PAL polypeptide was detected by Western blot analysis, along with two others at 74 and 83 kDa. Dual substrate activity was identified for the first time in the dicot Lens culinaris. Microbial Trichosporon cutaneum PAL (TcPAL) possessed the highest level of activity with Tyr of the sources investigated. Induction with Tyr (2 mM) produced the highest ratio of Phe:Tyr activity (1.6 ± 0.3: 0.4 ± 0.1 µmol/h g wet weight). TcPAL displayed Michaelis Menten kinetics with Phe (Km 5.0 ± 0.7 mM) but allosteric kinetics with Tyr (K' 1.7 ± 0.8 mM, Hill coefficient 1.8 ± 0.2). A greater specificity for Phe was demonstrated by a Phe [Vmax/Km] / Tyr [Vmax/Km] ratio of 2. The enzyme had a pH optimum of 8 - 8.5, temperature optimum of 32°C, showed no metal dependence, and had a monomer molecular mass of 79 kDa. Of the three methods investigated for purifying TcPAL, anion exchange chromatography using a Hi-Trap Q-Sepharose column produced the highest yield (20%) and purification fold (50). The PAL gene from Trichosporon cutaneum was cloned into the pET30a vector and sequenced. Five amino acid residues different from a previous report were identified, namely Arg74Glu, Val274Ala, Ala298Val, Ser322Pro and Arg486Lys. The gene had an intron of 1062 base pairs, starting at position 121. A His-Gln motif, which appears to be characteristic of yeast PALs with dual substrate activity, was identified in the substrate selectivity region. Residues that could potentially enhance the tyrosine activity of the enzyme were identified for future mutagenesis studies.

description: Using density functional theory calculations, we show that the binding strength of a graphene monolayer on Pd(111) can vary between physisorption and chemisorption depending on its orientation. By studying the interfacial charge transfer, we have identified a specific four-atom carbon cluster that is responsible for the local bonding of graphene to Pd(111). The areal density of such clusters varies with the in-plane orientation of graphene, causing the binding energy to change accordingly. Similar investigations can also apply to other metal substrates, and suggests that physical, chemical, and mechanical properties of graphene may be controlled by changing its orientation.

description: In this paper we study the influence of hadronic resonances on the phase diagram calculated with an effective chiral flavour SU(3) model. We show that varying the couplings of the baryonic resonances to the attractive scalar and the repulsive vector fields has a major impact on the order and location of the chiral phase transition and the possible existence of a critical end point as well as on the thermodynamic properties of the model. Furthermore, we study (strange) quark number fluctuations and show the related susceptibilities both at zero baryochemical potential and when crossing the phase transition line at three different points in the T-mu plane. We obtain the best agreement with current lattice data if we choose a rather strong vector coupling which in our model limits the phase transition to a smooth crossover and implies the non-existence of a critical end point.

Tearing Down the Ivory Tower: Demystifying Head of State Immunity in International Criminal Law

Subjects: International criminal law
Public international law

description: This paper discusses the concept of Head of State immunity in international law, which protects sitting heads of state from prosecution or lawsuits in foreign jurisdictions. The principle of immunity ensures sovereign equality among states and allows heads of state to carry out their duties without fear of legal proceedings. However, there are debates over whether a sitting head of state should be immune from prosecution for international crimes such as genocide, crimes against humanity, and war crimes. The establishment of the International Criminal Court (ICC) has challenged the traditional notion of head of state immunity and represents a powerful tool for holding individuals accountable for international crimes. The ICC's jurisdiction extends to crimes committed by heads of state and government, and it has underscored the importance of accountability for international crimes. The substantive content of international criminal law includes offenses such as genocide, crimes against humanity, war crimes, and the crime of aggression. The development of international criminal law has been influenced by law-making processes that have challenged the traditional positivistic state-centric view of international law.
On the origin of the 1/f spectrum in the solar wind magnetic field

description: We present a mechanism for the formation of the low frequency 1/f magnetic spectrum based on numerical solutions of a shell reduced-MHD model of the turbulent dynamics inside the sub-Alfvénic solar wind. We assign reasonably realistic profiles to the wind speed and the density along the radial direction, and a radial magnetic field. Alfvén waves of short periodicity (600 s) are injected at the base of the chromosphere, penetrate into the corona and are partially reflected, thus triggering a turbulent cascade. The cascade is strong for the reflected wave while it is weak for the outward propagating waves. Reflection at the transition region recycles the strong turbulent spectrum into the outward weak spectrum, which is advected beyond the Alfvénic critical point without substantial evolution. There, the magnetic field has a perpendicular power-law spectrum with slope close to the Kolmogorov -5/3. The parallel spectrum is inherited from the frequency spectrum of large (perpendicular) eddies. The shape is a double power-law with slopes of -1 and -2 at low and high frequencies respectively, the position of the break depending on the injected spectrum. We suggest that the double power-law spectrum measured by Helios at 0.3 AU, where the average magnetic field is not aligned with the radial (contrary to our assumptions) results from the combination of such different spectral slopes. At low frequency the parallel spectrum dominates with its characteristic 1/f shape, while at higher frequencies its steep spectral slope (-2) is masked by the more energetic perpendicular spectrum (slope -5/3).

description: This article examines remembrance as an intersecting site for Indigenous and German Studies. Attending to the practice of remembrance, it looks at learners’ relationships with different, difficult pasts as a way of teaching towards better futures. The authors—weaving together the voices of student and instructor—explore a future teacher’s intersectional experience of taking an Indigenous Education course in Canada while simultaneously teaching in an international placement in Germany. Examining her experiences of studying Canadian Indian Residential School history while also visiting Holocaust memorial sites, this educator considers complex questions of pedagogy, memory, and social change through a transdisciplinary dialogue.

Ensembles of physical states and random quantum circuits on graphs
Creators: name: Hamma, Alioscia

Publisher: name: arXiv
Year: 2012

description: In this paper we continue and extend the investigations of the ensembles of random physical states introduced in A. Hamma et al. [ http://prl.aps.org/abstract/PRL/v109/i4/e040502 Phys. Rev. Lett. 109, 040502 (2012)]. These ensembles are constructed by finite-length random quantum circuits (RQC) acting on the (hyper)edges of an underlying (hyper)graph structure. The latter encodes for the locality structure associated with finite-time quantum evolutions generated by physical i.e., local, Hamiltonians. Our goal is to analyze physical properties of typical states in these ensembles, in particular here we focus on proxies of quantum entanglement as purity and $α$-Renyi entropies. The problem is formulated in terms of matrix elements of superoperators which depend on the graph structure, choice of probability measure over the local unitaries and circuit length. In the $α=2$ case these superoperators act on a restricted multi-qubit space generated by permutation operators associated to the subsets of vertices of the graph. For permutationally invariant interactions the dynamics can be further restricted to an exponentially smaller subspace. We consider different families of RQCs and study their typical entanglement properties for finite-time as well as their asymptotic behavior. We find that area law holds in average and that the volume law is a typical property (that is, it holds in average and the fluctuations around the average are vanishing for the large system) of physical states. The area law arises when the evolution time is O(1) with respect to the size $L$ of the system, while the volume law arises as typical when the evolution time scales like O(L).

description: Quantum Mechanical weak values are an interference effect measured by the cross-Wigner transform W(ϕ,ψ) of the post-and preselected states, leading to a complex quasi-distribution ρ_{ϕ,ψ}(x,p) on phase space. We show that the knowledge of ρ_{ϕ,ψ}(z) and of one of the two functions ϕ,ψ unambiguously determines the other, thus generalizing a recent reconstruction result of Lundeen and his collaborators.
