description: A vertex subset S of a graph G is said to 2-dominate the graph if each vertex not in S has at least two neighbors in it. As usual, the associated parameter is the minimum cardinal of a 2-dominating set, which is called the 2-domination number of the graph G. We present both lower and upper bounds of the 2-domination number of cylinders, which are the Cartesian products of a path and a cycle. These bounds allow us to compute the exact value of the 2-domination number of cylinders where the path is arbitrary, and the order of the cycle is n $\equiv$ 0(mod 3) and as large as desired. In the case of the lower bound, we adapt the technique of the wasted domination to this parameter and we use the so-called tropical matrix product to obtain the desired bound. Moreover, we provide a regular patterned construction of a minimum 2-dominating set in the cylinders having the mentioned cycle order.

description: We consider intrinsic contributions to the spin Hall and spin Nernst effects in a bilayer graphene. The relevant electronic spectrum is obtained from the tight binding Hamiltonian, which also includes the intrinsic spin-orbit interaction. The corresponding spin Hall and spin Nernst conductivities are compared with those obtained from effective Hamiltonians appropriate for states in the vicinity of the Fermi level of a neutral bilayer graphene. Both conductivities are determined within the linear response theory and Green function formalism. The influence of an external voltage between the two atomic sheets is also included. We found transition from the topological spin Hall insulator phase at low voltages to conventional insulator phase at larger voltages.

description: We study the transverse flow throughout the mass range from $^{20}Ne+^{20}Ne$ to $^{131}Xe+^{131}Xe$ as a function of the impact parameter. We find that at smaller impact parameters the flow is negative while going through the impact parameter, transverse flow vanishes at a particular colliding geometry named GVF. We find that the mass dependence of GVF is insensitive to the equation of state and momentum dependent interactions whereas it is quite sensitive to the cross section. So it can act as a useful tool to pin down the nucleon nucleon cross section.

description: Noninteracting fermions, placed in a system with a continuous density of states, may have zeros in the $N$-fermion canonical partition function on the positive real $β$ axis (or very close to it), even for a small number of particles. This results in a singular free energy, and instability in other thermal properties of the system. In the context of trapped fermions in a harmonic oscillator, these zeros are shown to be unphysical. By contrast, similar bosonic calculations with continuous density of states yield sensible results.Noninteracting fermions, placed in a system with a continuous density of states yield sensible results.

description: We derive compact analytical formulae for all tree-level color-ordered gauge theory amplitudes involving any number of external gluons and up to three massless quark-anti-quark pairs. A general formula is presented based on the combinatorics of paths along a rooted tree and associated determinants. Explicit expressions are displayed for the next-to-maximally helicity violating (NMHV) and next-to-next-to-maximally helicity violating (NNMHV) gauge theory amplitudes. Our results are obtained by projecting the previously-found expressions for the super-amplitudes of the maximally supersymmetric Yang-Mills theory (N=4 SYM) onto the relevant components yielding all gluon-gluino tree amplitudes in N=4 SYM. We show how these results carry over to the corresponding QCD amplitudes, including massless quarks of different flavors as well as a single electroweak vector boson. The public Mathematica package GGT is described, which encodes the results of this work and yields analytical formulae for all N=4 SYM gluon-gluino trees. These in turn yield all QCD trees with up to four external arbitrary-flavored massless quark-anti-quark-pairs.

description: Peroxisome biogenesis disorders (PBDs) are nontreatable hereditary diseases with a broad range of severity. Approximately 65% of patients are affected by mutations in the peroxins Pex1 and Pex6. The proteins form the heteromeric Pex1/Pex6 complex, which is important for protein import into peroxisomes. To date, no structural data are available for this AAA+ ATPase complex. However, a wealth of information can be transferred from low-resolution structures of the yeast scPex1/scPex6 complex and homologous, well-characterized AAA+ ATPases. We review the abundant records of missense mutations described in PBD patients with the aim to classify and rationalize them by mapping them onto a homology model of the human Pex1/Pex6 complex. Several mutations concern functionally conserved residues that are implied in ATP hydrolysis and substrate processing. Contrary to fold destabilizing mutations, patients suffering from function-impairing mutations may not benefit from stabilizing agents, which have been reported as potential therapeutics for PBD patients.

description: We provide a method for the all order computation of small x contributions at the leading logarithmic level to cross-sections which are differential in rapidity. The method is based on a generalization to rapidity distributions of the high energy (or k_T) factorization theorem hitherto proven for inclusive cross-sections. We apply the method to Higgs production in gluon-gluon fusion, both with finite top mass and in the infinite mass limit: in both cases, we determine all-order resummed expressions, as well as explicit expressions for the leading small x terms up to NNLO. We use our result to construct an explicit approximate analytic expression of the finite-mass NLO rapidity distribution and an estimate of finite-mass corrections at NNLO.

Medico-ethical Considerations for Legalisation of Medicinal Cannabis in Malaysia
Creators: name: Yunus, Aimi Mohd
Publisher: name: Zenodo
Year: 2022
Subjects: Cannabis

description: There is an abundance of international studies that have lauded the benefits of medicinal cannabis for various illnesses. Likewise, local studies on cannabis in Malaysia that initially revolve around the harmful effects of cannabis misuse are increasingly shifting towards the benefits of medicinal use. Pursuant to scientific discovery of the medicinal benefits of cannabis, a myriad of literature begins to focus on the legality of utilising cannabis for medicinal purposes. Whilst many countries around the world, some of those including South East Asia countries have legalised medicinal cannabis, Malaysia is still lagging behind. As of now, there is no local study focusing on the legalisation of medicinal cannabis, leaving a gap in providing a reference to Malaysia's way forward on this issue. Under the current legislative regime, the use of cannabis is prohibited under the Dangerous Drugs Act (DDA) 1952 [Act 234]. However, the recent case of Muhammad Lukman Mohamad has sparked national interest that triggered calls for decriminalisation and legalisation of cannabis for medical reasons. Following these calls, it is pertinent to examine and critically analyse the medical, ethical, and legal considerations on the legalisation of medicinal cannabis in Malaysia. Such consideration is deemed necessary to protect the health and safety of patients. This research adopts an exploratory research design and employs a qualitative research approach in examining medical, ethical, legal, and theological considerations towards the legalisation of medicinal cannabis. Comparative legal analysis covers substantive and procedural components of jurisdictions in selected countries that have legalised medicinal cannabis such as the United Kingdom (UK), Canada, and Thailand. Examination of medico-ethical considerations is done using Biomedical Ethics Theory and Philosophical Theory. These considerations provide a comprehensive analysis of the legalisation of medicinal cannabis in Malaysia that will contribute to the current body of knowledge. This research proceeds to make several recommendations deemed relevant towards the legalisation of medicinal cannabis in Malaysia.
Development and application of consensus hit-calling protocols for the virtual screening of ‘undruggable’ and difficult drug targets
Creators: name: Ton, Anh-Tien
Publisher: name: University of British Columbia
Year: 2023

description: “Undruggable” or “difficult to drug” targets make up most of the human proteome; these proteins are described as such when it is considered impossible to pharmacologically target them. Therefore, “undruggable and difficult to drug” proteins represent significant challenges to the established drug discovery pipelines, but their successful inhibition would enable access to a wider range of therapeutic opportunities. In this thesis, we utilized various in silico tools to identify and design small molecule drug prototypes that could inhibit such undruggable and difficult targets. First, we introduced the recent development of new computer-aided drug design (CADD) methodologies and tools such as consensus docking, and Deep Docking. We then described the deployment of these innovative CADD methodologies to discover novel small molecule therapeutics against considered-as-difficult targets such as N-Myc, SARS-CoV-2 PLpro and Mpro. N-Myc is a highly desirable oncoprotein involved in many cancers and there is significant interest for targeting N-Myc in prostate cancer (PCa) and particularly in neuroendocrine prostate cancer (NEPC, an advanced, low-survival stage of PCa). However, N-Myc is considered an undruggable and unsuitable for small molecule inhibition due to its overall disordered structure. Thus, we developed new N-Myc specific small molecules with established and newly developed CADD protocols. Other examples of high value, but challenging targets are the viral main protease (Mpro) and the papain-like protease (PLpro) from severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2), as they are central pieces in its replication-transcription complex. However, intrinsic flexibility, multiple protonation state, solvent-exposed nature and other active site features unique to each protease decrease the success rate of conventional drug discovery protocols. Therefore, we discussed the identification of Mpro hits through naïve large virtual screening and ultra-large virtual screening that incorporated advanced consensus approaches. We also recapitulated the identification of new PLpro inhibitors through fine-tuned pharmacophore modelling and large-scale virtual screening with Deep Docking. In this thesis, we identified and designed small molecule inhibitors for each mentioned target of interest using state-of-the-art CADD methodologies. Notably, the compounds presented in this thesis provide the initial blueprints for the potential development of new anticancer and antiviral drugs.

description: A high resolution study of the electronic states 1^1Σ^+_u and 1^1Π_u which belong to the asymptote 4^1D + 5^1S and of the state 2(A)^1Σ^+_u, which correlates to the asymptote 5^1P + 5^1S, is performed by Fourier-transform spectroscopy of fluorescence progressions induced by single frequency laser excitation. Precise descriptions of the potentials up to 2000 cm^{-1} above the bottom are derived and compared to currently available ab initio calculations. Especially for the state 1^1Σ^+_u large deviations are found. Rather weak and local perturbations are observed for the states 1^1Π_u and 2^1Σ^+_u, while a strong coupling of the state 1^1Σ^+_u to the component Ω=0^+_u of the state 1^3Π_u, which belongs to the asymptote 5^3P + 5^1S, is indicated.

description: For $π^0η$-photoproduction on the nucleon formal expressions are developed for the five-fold differential cross section and the recoil polarization including beam and target polarizations. The polarization observables are described by various beam, target and beam-target asymmetries for polarized photons and/or polarized nucleons. They are given as bilinear hermitean forms in the reaction matrix elements divided by the unpolarized cross section. Numerical results for the linear and circular beam asymmetries for $γp\toπ^0ηp$ are obtained within an isobar model and are compared with existing data. Predictions are also given for the target asymmetry $T_{11}$, and the beam-target asymmetries $T^c_{10}$ and $T^c_{11}$ for circularly polarized photons.

description: We study the power control problem in wireless ad hoc networks with selfish users. Without incentive schemes, selfish users tend to transmit at their maximum power levels, causing significant interference to each other. In this paper, we study a class of incentive schemes based on intervention to induce selfish users to transmit at desired power levels. An intervention scheme can be implemented by introducing an intervention device that can monitor the power levels of users and then transmit power to cause interference to users. We mainly consider first-order intervention rules based on individual transmit powers. We derive conditions on design parameters and the intervention capability to achieve a desired outcome as a (unique) Nash equilibrium and propose a dynamic adjustment process that the designer can use to guide users and the intervention device to the desired outcome. The effect of using intervention rules based on aggregate receive power is also analyzed. Our results show that with perfect monitoring intervention schemes can be designed to achieve any positive power profile while using interference from the intervention device only as a threat. We also analyze the case of imperfect monitoring and show that a performance loss can occur. Lastly, simulation results are presented to illustrate the performance improvement from using intervention rules and compare the performances of different intervention rules.

Multiple Parton Interactions in Z+jets production at the LHC. A comparison of factorized and non--factorized double parton distribution functions

description: We examine the contribution of Multiple Parton Interactions to Z+n-jets production at the LHC, n=2,3,4, where the Z boson is assumed to decay leptonically. We compare the results obtained with the correlated GS09 double parton distribution function with those obtained with two instances of fully factorized single parton distribution functions: MSTW2008LO and CTEQ6LO. It appears quite feasible to measure the MPI contribution to Z+2/3/4 jets already in the first phase of the LHC with a total luminosity of one inverse femtobarn at 7 TeV. If as expected the trigger threshold for single photons is around 80 GeV, Z+2-jets production may well turn out to be more easily observable than the gamma+3-jets channel. The MPI cross section is dominated by relatively soft events with two jets balancing in transverse momentum.

description: A general expression for the four-point function with vanishing total R-charge of anti-chiral and chiral superfields in N=1 superconformal theories is given. It is obtained by applying the exponential of a simple universal nilpotent differential operator to an arbitrary function of two cross ratios. To achieve this the nilpotent superconformal invariants according to Park are focused. Several dependencies between these invariants are presented, so that eight nilpotent invariants and 27 monomials of these invariants of degree d>1 are left being linearly independent. It is analyzed, how terms within the four-point function of general scalar superfields cancel in order to fulfill the chiral restrictions.

Hysterectomy for endometriosis with or without ovarian preservation in British Columbia, Canada : a population based retrospective cohort study of post surgical outcomes
Creators: name: Long, Alicia
Publisher: name: University of British Columbia
Year: 2022

description: BACKGROUND: More research is needed comparing post-surgical outcomes between patients who undergo hysterectomy for endometriosis with or without ovarian conservation. OBJECTIVE: To compare the rate of reoperation and use of other pain-related health services after hysterectomy for endometriosis, with or without ovarian conservation METHODS: A population-based retrospective cohort study of 4489 patients aged 19-50 in British Columbia, Canada, undergoing hysterectomy for endometriosis between 2001 and 2016. Index surgeries were classified as: hysterectomy alone (conservation of both ovaries), hysterectomy with unilateral salpingoophorectomy (USO), or hysterectomy with bilateral salpingoophorectomy (BSO). Reoperation rate was the primary outcome. Secondary outcomes (measured at 3-12 months and 1-5 years after hysterectomy) included: physician visits for endometriosis and pelvic pain, prescriptions filled for opioids and hormonal suppression medications and hormone replacement therapy (HRT). RESULTS: 89.5% of patients remained reoperation free by the end of follow-up (median of 10 years, IQR = 6.1 to 14.3 years). Patients undergoing hysterectomy alone were more likely to undergo at least one reoperation compared to those having hysterectomy with BSO (13% vs 5%, p<0.0001), most commonly oophorectomy and adhesiolysis. When oophorectomy as reoperation was removed in a sensitivity analysis, this difference was attenuated. Secondary outcomes including physician visits for endometriosis or pelvic pain and rates of opioid prescriptions filled were similar between groups. The rate of prescriptions filled for hormonal suppression medications was low for all groups. The rate of prescriptions filled for HRT after hysterectomy with BSO was suboptimal - 60.6% filling at least one prescription at 3-12 months after index surgery. CONCLUSION: Patients who underwent hysterectomy with BSO had a lower reoperation rate than those who had hysterectomy with conservation of one or both ovaries. However, there was little difference between the groups for the secondary outcomes measured, suggesting that persistent pelvic pain after hysterectomy for endometriosis may not differ significantly based on ovarian conservation status. Moreover, HRT use after hysterectomy with BSO was suboptimal, which may have significant health consequences for these individuals undergoing premature surgical menopause. Therefore, strong consideration should be given to ovarian conservation at the time of hysterectomy for endometriosis.

description: We demonstrate the existence of orbital Coulomb phase as the exact ground state of p-orbital exchange Hamiltonian on the diamond lattice. The Coulomb phase is an emergent state characterized by algebraic dipolar correlations and a gauge structure resulting from local constraints (ice rules) of the underlying lattice models. For most ice models on the pyrochlore lattice, these local constraints are a direct consequence of minimizing the energy of each individual tetrahedron. On the contrary, the orbital ice rules are emergent phenomena resulting from the quantum orbital dynamics. We show that the orbital ice model exhibits an emergent geometrical frustration by mapping the degenerate quantum orbital ground states to the spin-ice states obeying the 2-in-2-out constraints on the pyrochlore lattice. We also discuss possible realization of the orbital ice model in optical lattices with p-band fermionic cold atoms.

 siendo limitada, notablemente la capacidad de mantener la atención y la recuperación de la
 memoria se relaciona con el cuerpo porque se reconstruyen aspectos sensoriomotores, las
 experiencias pasadas se reactivan incluso en el caso de la memoria, donde el conocimiento
 está codificado y basado en los sistemas cerebrales sensoriomotores de manera similar a lo
 que sucede con los recuerdos episódicos. La capacidad de guardar en la memoria los infantes
 no realizan grandes esfuerzos para almacenar o recordar nada, solamente sucede.
 La memoria de los niños depende más que de un esfuerzo mental específico que de
 la afectividad atada a las percepciones y esfuerzos voluntarios o intencionados por conservar
 o guardar algo en su memoria, probablemente porque, en esa etapa de sus vidas, se ven
 obligados aprender cosas con poca carga afectiva, de acuerdo a eso puede señalarse, como lo
 establece (Viramonte, 2000: 30) que los procesos cognitivos son aquellos que como la
 percepción, la atención y la memoria, se pueden producir sin la intervención consciente del
 sujeto y tienen una raíz biológica; no obstante, lo anterior no implica que el sujeto no pueda,
 ulteriormente, llegar a algún grado de control e intencionalidad en su realización.

description: We consider the Hartree equation with a smooth kernel and an external potential, in the semiclassical regime. We analyze the propagation of two initial wave packets, and show different possible effects of the interaction, according to the size of the nonlinearity in terms of the semiclassical parameter. We show three different sorts of nonlinear phenomena. In each case, the structure of the wave as a sum of two coherent states is preserved. However, the envelope and the center (in phase space) of these two wave packets are affected by nonlinear interferences, which are described precisely.

description: The authors report on the use of carbon nanofiber nanoemitters to ionize deuterium atoms for the generation of neutrons in a deuterium-deuterium reaction in a preloaded target. Acceleration voltages in the range of 50-80 kV are used. Field emission of electrons is investigated to characterize the emitters. The experimental setup and sample preparation are described and first data of neutron production are presented. Ongoing experiments to increase neutron production yields by optimizing the field emitter geometry and surface conditions are discussed.

description: In the present paper we set up a connection between the indices of the Tits algebras of a simple linear algebraic group $G$ and the degree one parameters of its motivic $J$-invariant. Our main technical tool are the second Chern class map and Grothendieck's $γ$-filtration. As an application we recover some known results on the $J$-invariant of quadratic forms of small dimension; we describe all possible values of the $J$-invariant of an algebra with orthogonal involution up to degree 8 and give explicit examples; we establish several relations between the $J$-invariant of an algebra $A$ with orthogonal involution and the $J$-invariant of the corresponding quadratic form over the function field of the Severi-Brauer variety of $A$.

Double layer in ionic liquids: Overscreening vs. crowding

description: We develop a simple Landau-Ginzburg-type continuum theory of solvent-free ionic liquids and use it to predict the structure of the electrical double layer. The model captures overscreening from short-range correlations, dominant at small voltages, and steric constraints of finite ion sizes, which prevail at large voltages. Increasing the voltage gradually suppresses overscreening in favor of the crowding of counterions in a condensed inner layer near the electrode. The predicted ion profiles and capacitance-voltage relations are consistent with recent computer simulations and experiments on room-temperature ionic liquids, using a correlation length of order the ion size.

High-altitude travel, exercise, and acclimatization in children
Creators: name: Rieger, Mathew Grant
Publisher: name: University of British Columbia

description: Important changes to oxygen sensing and delivery pathways occur between infancy and adulthood, but little is known about the function of these pathways during childhood. Considering increases in the popularity of high-altitude travel and recreation among families, it is unknown whether children respond and acclimatize to altitude in a similar fashion as adults, which may have implications for safety and recommendations for high altitude travel. The aim of this dissertation was to describe ventilatory, cerebrovascular, and cardiopulmonary acclimatization to high altitude in children and adults, and further describe similar processes within children native to high altitude. Study 1 provides an assessment of respiratory and cerebrovascular responses to exercise in Sherpa children living at 3800 m, demonstrating that cerebral blood flow velocity (CBFv, transcranial Doppler ultrasound) responses to exercise were not different between children native to high altitude, and lowland children at low altitude. Study 2 investigated changes in resting ventilation (VE), cerebral blood flow (CBF; duplex ultrasound), and pulmonary artery systolic pressure (PASP; echocardiography) with altitude and found that CBF and PASP changed similarly at 3000 m and 3800 m between children and adults, but the threshold for hypoxic hyperventilation was lower in children. Study 3 investigated changes in VE and CBF velocity (CBFv) during exercise during acclimatization to high altitude and found that CBFv during exercise was augmented in children on day 2 at 3800 m, but not on day 4, and was unchanged in adults at altitude. In study #4, we assessed symptoms of acute mountain sickness (AMS) and changes in body composition in children and adults across 7 days at 3000-3800 m. Among children and adults who developed AMS, the severity of symptoms was greater in children. Weight loss occurred sooner in children than adults, and children lost a greater proportion of total body water. These findings collectively reveal subtle differences in ventilatory and cerebrovascular acclimatization processes between children and adults but highlight a general stability of physiological responses during prolonged altitude exposure. An in-depth understanding of how children are impacted by hypoxia is critical to the advancement of high-altitude travel and health guidelines for families.
title: Using aircraft observations and modelling to improve understanding of mineral dust transport and deposition processes
Creators: name: Ratcliffe, Natalie
Publisher: name: University of Reading

description: With more than 400-3000 Mt of mineral dust lofted into the atmosphere annually,
dust affects the Earth’s radiation budget, hydrological and carbon cycles, human
health, energy production, aviation and more. Recent observations revealed that
coarse (5-10 µm) and super-coarse (10-62.5 µm) dust particles are more abundant
after long-range transport than expected. Having different impacts on the Earth
system than fine particles, it is vital that we understand how these particles travel
so far to fully comprehend the impacts of dust globally. In this thesis, I analyse the
dust size distribution evolution from the Sahara to the western Caribbean in aircraft
observations and compare to a climate model, then use the model to understand the
sensitivity of coarse particle lifetime to transport and deposition processes. I show
that the model deposits coarse particles too quickly, resulting in an underestimation
of dust mass of increasing orders of magnitude with westwards transport. Processes
in the model which may increase coarse transport are tested. Coarse dust is shown to
be most sensitive to sedimentation, with reductions in sedimentation beyond 80%
increasing the volume size distribution by up to 7 orders of magnitude, bringing
the model into agreement with observations. Convective and turbulent mixing,
impaction scavenging, and shortwave absorption are found to have minimal impact
on long-range transport of coarse particles. Raising the dust in the model to 5km
at the Sahara with the hope to increase long-range transport is shown to increase
particle lifetime, though the coarsest dust is still deposited within 24 hours. Findings
in this thesis suggest the presence and importance of processes not in the model
which could counteract sedimentation, such as asphericity and electric charging, and
suggest that explicit convection representation could improve model transport. This
work demonstrates the need for thorough research of these undetermined processes
to accurately model size distribution evolution.

description: With an emphasis on tackling the alarming increase in dropout rates among Malawian students, this study tackles the vital concerns of fairness and accessibility in Malawian elementary education. The study uses a qualitative method to clarify the opinions and experiences of significant stakeholders and to expose the complex interplay of factors that contribute to this pervasive challenge. Focus groups, in-depth interviews, and document analysis were used to collect qualitative data from a range of participant groups, including students, teachers, parents, and educa-tion officials, and to gain crucial insights into the state of education. With the use of these methods, the complexity of the problem was examined, and a thorough understanding of the challenges Malawian primary education faced was produced. According to the study's findings, the rising dropout rates are the result of a complicated web of circumstances. Due to the significant challenges faced by economically disadvantaged students in their educational endeavours, the subject of socioeconomic disparities has gained significant importance. There were also obvious gen-der differences, with early marriages and teenage pregnancies typically having an excessively negative effect on fe-males. The opinions and firsthand accounts of Malawian students provided valuable insights into the challenges they encounter when trying to get into and stay in school. Firsthand narratives brightened the difficulties that learners encounter, including risky and lengthy travels to school as well as inadequate facilities and educational resources. The study evaluated the effectiveness of government initiatives and programs created to lessen the dropout pan-demic.
Spin flips I: Evolution of the angular momentum orientation of Milky Way-mass dark matter haloes

description: During the growth of a cold dark matter halo, the direction of its spin can undergo rapid changes. These could disrupt or even destroy a stellar disc forming in the halo, possibly resulting in the generation of a bulge or spheroid. We investigate the frequency of significant changes in the orientation of the angular momentum vector of dark matter haloes ("spin flips"), and their degree of correlation with mergers. We focus on haloes of mass similar to that of the Milky Way (MW) halo at redshift z=0 (log M/(Msol/h) = 12.0 to 12.5) and consider flips in the spin of the whole halo or just its inner parts. We find that a greater fraction of major mergers are associated with large spin flips than minor mergers. However, since major mergers are rare, the vast majority (93%) of large whole-halo spin flips (angle change >= 45 degrees) coincide with small mass changes, not major mergers. The spin vector of the inner halo experiences much more frequent flips than the halo as a whole. Over their entire lifetimes (i.e. after a halo acquires half of its final mass), over 10% of halos experience a flip of at least 45 degrees in the spin of the entire halo and nearly 60 percent experience a flip this large in the inner halo. These numbers are reduced to 9 percent for the whole halo and 47 percent for the inner halo when we consider only haloes with no major mergers after formation. Our analysis suggests that spin flips (whose effects are not currently included in galaxy formation models) could be an important factor in the morphological transformation of disc galaxies.
