On the quaternary structure and gating of the bacterial protein translocation channel
Creators: name: Dalal, Kush
Publisher: name: University of British Columbia
Year: 2012

description: The SecY protein-conducting channel associates with different cytosolic partners to drive the translocation of preprotein substrates across the bacterial inner membrane. In this thesis, several outstanding questions regarding the structure and function of the SecY channel are addressed. Our first study is motivated by the poorly defined interactions between the channel and its binding partners. We characterize the binding mode and stoichiometry of two SecY interacting proteins, the SecA ATPase and Syd, which each form 1:1 complexes with the channel. In the second study, we isolate the SecY dimer (i.e. two SecY channels), which is shown to be essential to activate the SecA ATPase activity and support protein transport. Analysis of SecY dimers in vivo further demonstrates that each constituent SecY copy has a different role in the translocation reaction. Finally, we discover that the SecY channel, in addition to transporting preprotein substrates, is also highly specific for monovalent anions. This selective conductance explains why translocation does cause a general membrane permeability and cell death. Our findings are discussed in the broader context of genetic, biochemical and structural information on the SecY channel and other translocation components.

description: We study light-assisted collisions in an ensemble containing a small number (~3) of cold Rb87 atoms trapped in a microscopic dipole trap. Using our ability to operate with one atom exactly in the trap, we measure the one-body heating rate associated to a near-resonant laser excitation, and we use this measurement to extract the two-body loss rate associated to light-assisted collisions when a few atoms are present in the trap. Our measurements indicate that the two-body loss rate can reach surprisingly large values beta>10^{-8} cm^{3}.s^{-1} and varies rapidly with the trap depth and the parameters of the excitation light.

description: Purpose: This study investigated the efficacy of Treatment for Establishing Motor Program Organization (TEMPOSM) in childhood apraxia of speech (CAS). Method: A mixed between- and within-participant design with multiple baselines across participants and behaviors was used to examine acquisition, generalization, and maintenance of skills. TEMPOSM was administered in four one-hour sessions a week over a four-week period for eleven participants (ages 5 to 8), allocated to either an immediate treatment group or a wait-list control group. Acoustic and perceptual variables were measured at baseline, immediate post-treatment, and one-month post-treatment. Results: Children demonstrated significant improvements in specific acoustic measures of segmentation and lexical stress, as well as perceptual measures of fluency, lexical stress, and speech-sound accuracy. Treatment and generalization effects were maintained one-month post-treatment with generalization to untreated stimuli. Conclusion: TEMPOSM was efficacious in improving segmental and suprasegmental impairments in the speech of children with CAS.

The Roman-Campanian Hermaphroditus: Visual Representations and the Performative Body under Dionysus

description: Hermaphroditus is an intersex deity, described and depicted in ancient sources as having female breasts and a male phallus. Scholars have fixated on the phallic nature of the deity, often interpreting Hermaphroditus as symbolizing fertility, sexual union, marriage, or serving an apotropaic function in the ancient world. However, what if this is a common misconception? My study re-examines what we know of Hermaphroditus by focusing on artistic representations of the deity found in the Campanian region of Italy, looking specifically at material remains found in Roman domūs and villas. I draw on recent studies of gender and sexuality in the ancient world to interpret Hermaphroditus as an object of attraction rather than one of fear or revulsion. I argue that Hermaphroditus finds a place within the Dionysian sphere, with the intersex deity iconographically linked to the god of wine and theatre, as well as spatially and socio-culturally tying Hermaphroditus to the Roman concept of otium, convivial settings, and garden spaces. The inclusion of Hermaphroditus within the sphere of Dionysus, provides Hermaphroditus with a space where hir gender androgyny serves performative roles. Hermaphroditus not only exhibits features of gender performativity, but also role-plays as identifiable motifs such as the sleeping maenad/Ariadne, the woman at her toilette, and even Dionysus himself. I further link this performativity to a theatrical environment where Hermaphroditus displays parallels with gender ambiguous performers such as pantomime dancers. I conclude with an exercise in viewing Ovid’s story of Hermaphroditus and Salmacis found in his Metamorphoses as a possible source for adapted pantomime libretti and looking for artistic representations of the intersexed deity as serving as a visual metonym for performers and performative space. By redefining Hermaphroditus as the embodiment of idealized male youth and female gender, the androgyny is reconceptualized within the liminality of Dionysian space. This allows for new understandings of sex and gender, creating a space for identities of marginalized groups where androgyny may not be recognized as conventional within Roman society but was still coveted for its beauty and sexual appeal.
Motivation and self-regulated learning strategies accounting students adopt in a blended learning environment

Subjects: classificationCode: 350199
subject: Accounting, auditing and accountability not elsewhere classified

description: As future professionals, tertiary accounting students require strategies to learn in an autonomous and self-directed blended learning environment. Consequently, this research seeks to understand what motivates students to engage with learning resources as provided through a learning management system, what self-regulated learning strategies they adopt, and whether these strategies change over time. Such insights facilitate creation of future learning resources and ways of engaging. Findings reveal students are intrinsically and extrinsically motivated to engage with the learning resources to enhance understanding. They apply strategies of rehearsal, elaboration, metacognitive self-regulation, goal setting and reflection, which evolve as they progress with their studies.

description: This dissertation examines whether the social ties between a CEO and independent directors, which are created through school affiliation, work experience, or social activities, affect a firm’s decision to engage in corporate tax strategies. Consistent with the argument that CEO-board social ties weaken a board’s monitoring and enhance a board’s informed advice, this dissertation finds that firms with a higher proportion of CEO-board social ties engage in greater corporate tax strategies. Thus, this dissertation suggests that policymakers reconsider the definition of director independence, while both firms and investors need to be aware of the tax-related implications of CEO-board social ties.

description: The observational relation between the density of baryon and dark matter in the Universe, $Ω_{\rm DM}/Ω_B\simeq 5$, is one of the most difficult problems to solve in modern cosmology. We discuss a scenario that explains this relation by combining the asymmetric dark matter scenario and the spontaneous baryogenesis associated with the flat direction in the supersymmetric standard model. A part of baryon asymmetry is transferred to charge asymmetry $D$ that dark matter carries, if a symmetry violating interaction that works at high temperature breaks not only $B-L$ but also $D$ symmetries simultaneously. In this case, the present number density of baryon and dark matter can be same order if the symmetric part of dark matter annihilates sufficiently. Moreover, the baryon number density can be enhanced as compared to that of dark matter if another $B-L$ violating interaction is still in thermal equilibrium after the spontaneous genesis of dark matter, which accommodates a TeV scale asymmetric dark matter model.

description: Precise tests of Lorentz invariance in neutrinos can be performed using long baseline experiments such as MINOS and OPERA or neutrinos from astrophysical sources. The MINOS collaboration reported a measurement of the muonic neutrino velocities that hints to super-luminal propagation, very recently confirmed at 6 sigma by OPERA. We consider a general parametrisation which goes beyond the usual linear or quadratic violation considered in quantum-gravitational models. We also propose a toy model showing why Lorentz violation can be specific to the neutrino sector and give rise to a generic energy behaviour E^alpha, where alpha is not necessarily an integer number. Supernova bounds and the preferred MINOS and OPERA regions show a tension, due to the absence of shape distortion in the neutrino bunch in the far detector of MINOS. The energy independence of the effect has also been pointed out by the OPERA results.

description: In this paper, we discuss and value variance, volatility, covariance, and correlation swaps in the Vasicek, Schwartz one-factor, and Heston models using a continuous-time regime. The data used is primarily 2019 natural gas and crude oil futures closing prices due to the liquidity and size of the options market in the commodity energy sector. We derive approximations for covariance and correlation swap fair strikes in the Heston model following the continuous time regime, using the discrete regime for reference. We check the accuracy of our approximation using simulated error distributions of the calibrated parameters from the CIR component of the Heston model. We present the effect of varied parameters on the value of the fair strikes for covariance and correlation swaps. Finally, we evaluate the fair strikes of covariance and correlation swaps using three different approximations, yielding values and error bounds of dramatically varying sizes, demonstrating the limitations of the GARCH(1,1) calibration of the Heston model.
Adverse Childhood Experiences and Intimate Partner Violence: A Meta-Analysis

Publisher: name: Arts
Year: 2022
Subjects: subject: Adverse childhood experiences
subject: Intimate partner violence
subject: Psychology--Clinical

description: Background: Intimate partner violence (IPV) represents a significant public health concern that impacts individuals globally. Exposure to adverse childhood experiences (ACEs) represents one risk factor for IPV involvement. However, the results of existing research on the association between ACEs and IPV have demonstrated somewhat mixed results. Given the heterogeneity of existing findings, the overall effect size of the association between ACEs and IPV was examined, to in turn inform policy, knowledge translation, prevention, and intervention efforts. Objectives: The present research sought to meta-analytically examine the association between ACEs and (1) IPV perpetration and (2) IPV victimization. Additionally, moderator analyses were conducted to determine demographic factors and study characteristics that may impact the association between ACEs and IPV involvement Method: Electronic searches were conducted in MEDLINE, Embase, and PsycINFO in August of 2021. One-hundred and twenty-three records were screened for inclusion. All studies must have included a measure of ACEs (i.e., 8-item, 10-item, or other composite measure) and a measure of IPV victimization or perpetration (e.g., physical, sexual, or psychological abuse). Results: Among the 27 studies and 41 samples included in the present meta-analysis, 65,330 participants were included. Across all included studies, 33.84% of participants identified as male and the mean age was 32.10 years (age range, 14-56.9). The results of the meta-analyses demonstrated that ACEs were positively associated with IPV perpetration [k = 15, r = .172, (95% CI: .119, .223), p < .001], and victimization [k = 26, r = .200, (95% CI: .143, .255) p < .001]. Results of the moderator analysis demonstrated that the association between ACEs and IPV perpetration and victimization was stronger among studies that examined mixed IPV (i.e., more than one type of IPV) compared to physical IPV exclusively. The association between ACEs and IPV victimization was also stronger among studies that included younger participants and among more recently published studies. Conclusions: The present meta-analyses demonstrate a need for trauma-informed and early approaches to IPV screening, prevention, and intervention. Further, significant moderators identified in the present meta-analyses contribute to a stronger understanding of factors that amplify or attenuate risk for IPV among individuals with ACEs exposure. Future research should build upon these results to help inform resiliency factors that may mitigate risk for IPV.

description: Aims. We study the analogy between local U/LIRGs and high-z massive SFGs by comparing basic Hα structural characteristics, such as size, and luminosity (and SFR) surface density, in an homogeneous way (i.e. same tracer and size definition, similar physical scales). Methods. We use Integral Field Spectroscopy based Hα emission maps for a representative sample of 54 local U/LIRGs (66 galaxies). From this initial sample we select 26 objects with Hα luminosities (L(Hα)) similar to those of massive (i.e. M\ast \sim 10^10 M\odot or larger) SFGs at z \sim 2, and observed on similar physical scales. Results. The sizes of the Hα emitting region in the sample of local U/LIRGs span a large range, with r1/2(Hα) from 0.2 to 7 kpc. However, about 2/3 of local U/LIRGs with Lir > 10^11.4 L\odot have compact Hα emission (i.e. r1/2 < 2 kpc). The comparison sample of local U/LIRGs also shows a higher fraction (59%) of objects with compact Hα emission than the high-z sample (25%). This gives further support to the idea that for this luminosity range the size of the star forming region is a distinctive factor between local and distant galaxies of similar SF rates. However, when using Hα as a tracer for both local and high-z samples, the differences are smaller than the ones recently reported using a variety of other tracers. Despite of the higher fraction of galaxies with compact Hα emission, a sizable group (\sim 1/3) of local U/LIRGs are large (i.e. r1/2 > 2 kpc). These are systems showing pre-coalescence merger activity and they are indistinguishable from the massive high-z SFGs galaxies in terms of their Hα sizes, and luminosity and SFR surface densities.

description: This thesis examines how organisational learning occurs in an authoritarian and coercive environment. It demonstrates that actors can create conditions for learning to take place in an environment formerly thought of as being ill-suited to learning. This thesis has implications for practice, as organisations often practice control on a continuum ranging from enabling to coercive, only one end of which is traditionally viewed as being conducive to learning according to current literature.

description: The current investigation examined perceptual and movement responses to evaluate the possibility of unique representations guiding the outcomes of perceptual and motor-based responses. In two experiments the quality of visual luminance edges was manipulated and the outcomes of three visually based tasks, namely perceptual estimates, pointing, and prehensile/grasping movements were measured. The findings provided evidence for the use of unique representations of stimulus features that are task specific.

description: This thesis investigates how the interplay between managerial ability (i.e., ability of the top management team), managerial discretion, and monitoring quality influences just in time (JIT) inventory management. While literature shows that inventory efficiency is highly valued by investors, to date there has been a lack of empirical evidence on the importance of skilled human capital on the efficient management of JIT inventory. Findings suggest that managerial ability contributes to efficiency in JIT inventory management, with the extent of such efficiency being conditional on the level of discretion granted to managers and the effective monitoring of this discretion.

description: This thesis examines whether equity compensation incentivises executives to make efficient labour investment decisions. Specifically, it examines whether the components of equity compensation — stock options and restricted stock — affect over- and under-investment in labour. Based on a sample of 12118 firm-year observations from 1992 to 2014, it is found that stock options exacerbate over-investment and mitigate under-investment in labour. In contrast, restricted stock is found to mitigate both over- and under-investment in labour. Overall, the findings demonstrate that stock options and restricted stock matter in executives’ labour investment decisions.

description: This thesis examines how a firm's exposure to exchange rates affects the properties of analysts' earnings forecasts. All firms, regardless of whether they are involved in international or purely domestic trade, are conceptually affected by changes in currency values. Results suggest that firms with greater foreign exchange exposure have greater analysts' forecast errors and dispersion, and attract lower analyst coverage. Additional tests reveal insights regarding how improved disclosures, annual report readability and analysts' experience can alleviate the negative impacts of foreign exchange exposure. The results of this study have several practical implications for investors, firms, analysts and standard setters.
The role of environment in low-level active galactic nucleus activity: no evidence for cluster enhancement

description: We use the AMUSE-Virgo and AMUSE-Field surveys for nuclear X-ray emission in early-type galaxies to conduct a controlled comparison of low-level supermassive black hole activity within cluster and field spheroids. While both the Virgo and the Field samples feature highly sub-Eddington X-ray luminosities (log L_x/L_Edd between -8 and -4), we find that after accounting for the influence of host galaxy stellar mass, the field early-type galaxies tend toward marginally greater (0.38+/-0.14 dex) nuclear X-ray luminosities, at a given black hole mass, than their cluster counterparts. This trend is qualitatively consistent with the field black holes having access to a greater reservoir of fuel, plausibly in the form of cold gas located near the nucleus. We are able to rule out at high confidence the alternative of enhanced X-ray activity within clusters. Presuming nuclear X-ray emission correlates with the total energy and momentum output of these weakly accreting black holes, this indicates that low-level active galactic nucleus feedback is not generally stronger within typical cluster galaxies than in the field. These results confirm that for most cluster early-type galaxies (i.e., excluding brightest cluster galaxies) direct environmental effects, such as gas stripping, are more relevant in quenching star formation.

description: Among the most important factors in wireless base-stations design are link speed and power efficiency. For a faster wireless connection, the MIMO beamforming technology, higher-order QAM signals, and wider bandwidth signals are used. To increase the power efficiency in transmitters, the PAs are pushed to operate in nonlinear regions where they present their highest power efficiency. These techniques increase in-band and out-of-band distortions of the MIMO wireless transmitters, resulting in signal quality degradation. To mitigate the introduced distortions to the transmitted signal, Digital Pre-Distortion (DPD) is used. However, the conventional DPD techniques cannot meet the strict timing requirements of 5G and 6G wireless connections. The transmitter nonlinearities are a function of various parameters such as input signal average power and ambient temperature and steering angle in the case of beamforming. This thesis studies the effect of ambient temperature and signal’s average power on high-power PAs and proposes a novel DPD technique to mitigate the effect of those parameters on the PA behaviour. In another research, the effect of beamforming on the transmitter performance in terms of signal quality and out-of-band distortions are studied. A novel angle inclusive DPD for beamforming application is introduced to remove beamforming-related distortions and enhance the signal quality. This technique provides an uninterrupted linearization at any beam direction. The developed algorithms are verified using a realistic MIMO beamforming setup designed in the laboratory. The measurement results have shown that by using the proposed technique, the signal quality is substantially improved when compared to state-of-the-art techniques.

description: A cryptocurrency wallet is a software stored in a user's device, such as a mobile phone or personal computer. This wallet software holds a public-private key pair that is used for digital cryptocurrency transactions, like Bitcoin. The private key is used to access, authorize and sign transactions, hence it should be secured. The public key on the other hand, serves as the user's public address. Mobile phones and personal computers are susceptible to device failure, external attacks, theft and loss. In the event of a user's device failure, the private key could become inaccessible. If the device is lost or stolen, the private key would fall into the wrong hands and the user will irrecoverably lose their funds. This thesis addresses the question of secure storage of the private key. More precisely, we study this problem such that the following conditions are satisfied: (i) The private key is broken into shares and stored on remote servers; (ii) A user can retrieve their private key by triggering a reconstruction protocol using only a human-memorable password, and the reconstruction is successful as long as at least some threshold number of servers are honest and available. We have designed and implemented a Password Protected Secret Sharing (PPSS) scheme, that can be used to construct a system that satisfies the above. Our PPSS uses two building blocks: (i) Threshold Password-Authenticated Key Exchange (TPAKE) protocol (for authentication); and (ii) A symmetric key encryption scheme (to emulate secure channels for sending the shares). The user divides the private key into shares, and stores each share on a different remote server. When the key is needed, the user enters their password to the device, and the device will reconstruct the secret key by contacting the servers and obtaining the stored shares. Our protocol is provably secure under Computational Diffie-Hellman (CDH) assumption, while providing state-of-the-art security guarantees. We give an implementation as an application for a mobile phone. Efficiency analysis shows that the proposed system is highly deployable.

description: The paper describes the refinement algorithm for the Calculus of (Co)Inductive Constructions (CIC) implemented in the interactive theorem prover Matita. The refinement algorithm is in charge of giving a meaning to the terms, types and proof terms directly written by the user or generated by using tactics, decision procedures or general automation. The terms are written in an "external syntax" meant to be user friendly that allows omission of information, untyped binders and a certain liberal use of user defined sub-typing. The refiner modifies the terms to obtain related well typed terms in the internal syntax understood by the kernel of the ITP. In particular, it acts as a type inference algorithm when all the binders are untyped. The proposed algorithm is bi-directional: given a term in external syntax and a type expected for the term, it propagates as much typing information as possible towards the leaves of the term. Traditional mono-directional algorithms, instead, proceed in a bottom-up way by inferring the type of a sub-term and comparing (unifying) it with the type expected by its context only at the end. We propose some novel bi-directional rules for CIC that are particularly effective. Among the benefits of bi-directionality we have better error message reporting and better inference of dependent types. Moreover, thanks to bi-directionality, the coercion system for sub-typing is more effective and type inference generates simpler unification problems that are more likely to be solved by the inherently incomplete higher order unification algorithms implemented. Finally we introduce in the external syntax the notion of vector of placeholders that enables to omit at once an arbitrary number of arguments. Vectors of placeholders allow a trivial implementation of implicit arguments and greatly simplify the implementation of primitive and simple tactics.

description: Biomass photorefinery for simultaneous production of value-added chemicals and sustainable hydrogen holds a promising perspective for achieving a negative carbon economy scenario. However, an insight into the light-driven lignin depolymerization approach is still lacking due to the highly complex structure and constitution. Lignin corresponds to 15-30% of biomass weight and is the major renewable source of aromatics in nature, and still, most of it is used as low-grade solid fuel. This work aimed to address this challenge by designing a series of Zn1-xCdxS solid solutions photocatalysts to study the depolymerization mechanism of lignin model compounds. Bandgap engineering strategy was used by changing the Zn/Cd ratio, which is a proven method to regulate the reaction pathway. Specifically, Zn0.5Cd0.5S (ZCS50) demonstrated the best substrate conversion to mono phenolic compounds achieving 27% conversion in 2 hours. It was also observed that different reaction pathways could occur depending on the photocatalyst's band structure, which directly affected product distribution. For instance, the application of Zn0.75Cd0.25S (ZCS25) led to the highest hydrogen yield, which is considered a side product with large importance for biorefineries, however it presented low overall depolymerization of lignin. Finally, the photocatalyst with better performance, ZCS50, was applied in the conversion of two different types of lignin to demonstrate its applicability. After 16h reaction, a wide range of monomeric aromatics were detected as products with simultaneous H2 production, but a low conversion was observed. Nevertheless, the present study could demonstrate excellent examples of biomass valorization by fine designing photocatalysts with room for future optimization.

description: Experimental X-ray crystallography, NMR (Nuclear Magnetic Resonance) spectroscopy, dual polarization interferometry, etc are indeed very powerful tools to determine the 3-Dimensional structure of a protein (including the membrane protein); theoretical mathematical and physical computational approaches can also allow us to obtain a description of the protein 3D structure at a submicroscopic level for some unstable, noncrystalline and insoluble proteins. X-ray crystallography finds the X-ray final structure of a protein, which usually need refinements using theoretical protocols in order to produce a better structure. This means theoretical methods are also important in determinations of protein structures. Optimization is always needed in the computer-aided drug design, structure-based drug design, molecular dynamics, and quantum and molecular mechanics. This paper introduces some optimization algorithms used in these research fields and presents a new theoretical computational method - an improved LBFGS Quasi-Newtonian mathematical optimization method - to produce 3D structures of Prion AGAAAAGA amyloid fibrils (which are unstable, noncrystalline and insoluble), from the potential energy minimization point of view. Because the NMR or X-ray structure of the hydrophobic region AGAAAAGA of prion proteins has not yet been determined, the model constructed by this paper can be used as a reference for experimental studies on this region, and may be useful in furthering the goals of medicinal chemistry in this field.

description: In recent years it has been learned that scalar superpartner masses and trilinear couplings should both generically be larger than about 20 TeV at the short distance string scale if our world is described by a compactified string or M-theory with supersymmetry breaking and stabilized moduli. Here we study implications of this, somewhat generally and also in detail for a particular realization (compactification of M-theory on a G_2 manifold) where there is significant knowledge of the superpotential and gauge kinetic function, and a light gluino. In a certain sense this yields an ultraviolet completion of minimal flavour violation. Flavour violation stems from off-diagonal and non-universal diagonal elements of scalar mass matrices and trilinear couplings, and from renormalization group running. We also examine stability bounds on the scalar potential. While heavy scalars alone do not guarantee the absence of flavour problems, our studies show that models with heavy scalars and light gluinos can be free from such problems.
