Cognitive recovery in acute stroke: Measurement and facilitation of change
Creators: name: Tehan, Hannah
Publisher: name: Australian Catholic University
Year: 2015

description: Strokes can affect any part of the brain and therefore have a wide range of potential outcomes including an array of cognitive deficits such as memory problems, neglect, problem solving difficulties and decision making errors. From a biological perspective, recovery from stroke can be categorized into two time phases, acute (up until 3 months) and chronic (3+ months), with most changes occurring in the actue phase. In the motor and speech areas, it is recognised that early intervention during the acute phase leads to the best long-term outcomes. The research into recovery of cognitive function is less well developed than in the motor and speech areas, however, there is a literature that explores the prevalence of cognitive impairments and recovery in the chronic phase. Such research is based upon patients with stroke’ performance on batteries of standardised neuropsychological tests. This literature consistently demonstrates only small improvements over time. Training programs aimed at directly facilitating the recovery process, as opposed to developing compensatory behaviours to circumvent the effects of the impairment, have been implemented during the chronic phase. Many of these programs are based upon cognitive theories and employ commonly used cognitive psychology paradigms. These training programs have resulted in substantial improvements in the impaired functions. However, there are no studies that attempt to track changes in behaviour during the acute phase of stroke despite this being consistently demonstrated as a crucial period of recovery. The intent of the current research is to address this gap in the literature by exploring behaviour change in patients with stroke who are in hospital in the early stages of recovery from their first stroke.
Fading features found in the kinematics of the far-reaching Milky Way stellar halo

description: We test the long-term kinematical stability of a Galactic stellar halo model, due to Kafle et al. (2012), who study the kinematics of approximately 5000 blue horizontal branch (BHB) stars in the Sloan Digital Sky Survey (SDSS). The velocity dispersion σ and anisotropy parameter β of the stars have been determined as functions of Galactocentric radius, over the range 6 < RGC < 25 kpc, and show a strong dip in the anisotropy profile at RGC ∼ 17 kpc. By directly integrating orbits of particles in a 3-D model of the Galactic potential with these characteristics, we show that the σ and β profiles quickly evolve on a time scale of a few × 10 Myr whereas the density ρ profile remains largely unaffected. We suggest that the feature is therefore transient. The origin of such features in the Galactic halo remains unclear.

Bioengineering microbial communities: Their potential to help, hinder and disgust

Publisher: name: Swinburne
Year: 2024

description: ABSTRACT: The bioengineering of individual microbial organisms or microbial communities has great potential in agriculture, bioremediation and industry. Understanding community level drivers can improve community level functions to enhance desired outcomes in complex environments, whereas individual microbes can be reduced to a programmable biological unit for specific output goals. While understanding the bioengineering potential of both approaches leads to a wide range of potential uses, public acceptance of such technology may be the greatest hindrance to its application. Public perceptions and expectations of 'naturalness,' as well as notions of disgust and dread, may delay the development of such technologies to their full benefit. We discuss these bioengineering approaches and draw on the psychological literature to suggest strategies that scientists can use to allay public concerns over the implementation of this technology.

title: State Space Search in Fuzzing
Creators: name: Herrera, Adrian
Publisher: name: The Australian National University
Year: 2024

description: Coverage-guided fuzzers are an indispensable tool in the software-testing toolbox. They uncover bugs in a target program by subjecting it to a large number of automatically-generated inputs. The fuzzer generates these inputs to search the corners of the target's (potentially vast) state space, where bugs are more likely to lurk. While fuzzers have successfully uncovered bugs in a range of targets, they struggle to discover ``deep bugs'' (i.e., bugs triggered under a complex set of control and data dependencies). Moreover, security professionals deploying fuzzers lack observability into fuzzers' state space search (and thus an understanding of why these deep bugs are missed). This dissertation presents a set of techniques for reasoning about and improving a fuzzer's state space search, ultimately enhancing a fuzzer's bug-finding ability. First, we consider the task of bootstrapping this search process. Fuzzers typically require an initial set of seeds (exemplar inputs accepted by the target) to kickstart their state space search. We empirically evaluate various methods for selecting these seeds, designing an optimal technique for reducing large seed sets in the process. Second, we develop a new state space abstraction. Fuzzers traditionally abstract a target's state space based on control-flow features. We present an abstraction based on data-flow features and demonstrate how our data-flow-based abstraction uncovers bugs that traditional fuzzers fail to find. Finally, we investigate how best to measure a fuzzer's state space search after a fuzzing campaign. We use static analysis to quantify a target's state space, allowing us to measure how much of this state space a fuzzer has explored. We empirically evaluate several modern static analysis frameworks and propose new approaches for assessing a fuzzer's state space search.
Characteristics of collaboration between nurse practitioners and medical practitioners in primary healthcare: A multiple case study using mixed methods
Creators: name: Schadewaldt, Verena
Publisher: name: Australian Catholic University
Year: 2015

description: Collaborative work between nurse practitioners (NPs) and medical practitioners (MPs) in primary healthcare (PHC) settings is a novel approach to patient care in Australia. Hence, this multiple case study using mixed methods aimed to identify the conceptual and practical aspects of collaboration between NPs and MPs in Australian PHC settings. The rationale for conducting this study was to provide practitioners and policy-makers with information about the likely barriers and facilitators of collaborative practice models and current experiences of collaboration in PHC settings. This has not been examined before in Australia. Specifically, this study sought to answer three research questions: 1) What is the conceptual basis of collaboration as defined by NPs and MPs? 2) What are NPs’ and MPs’ experiences of collaborative practice? 3) What are the factors that enable the functioning of collaborative practice models?

description: Auxetic materials and structures have a negative Poisson's ratio. When a tensile load is applied, they become thicker in lateral direction and vice versa. This paper presents a study on the mechanical behavior of a metallic re-entrant honeycomb auxetic structure manufactured by laser assisted Direct Metal Deposition (DMD) additive manufacturing technology. Effective modulus of the auxetic structure was estimated in tensile loading. The results of finite element analysis (FEA) were validated experimentally and show good agreement. Poisson's ratio of the given structure was also estimated by FEA and validated with the analytical equation. Results show that direct metal deposition is an effective technique for producing intricate auxetic structures for various engineering applications.
Biceps femoris long head architecture: The association with hamstring injury and response to training
Creators: name: Timmins, Ryan
Publisher: name: Australian Catholic University
Year: 2015

description: Hamstring strain injuries (HSIs) are the most common injury in many running based sports, and following the initial insult the risk of recurrence remains high. In order to reduce the risk of a hamstring strain re-injury, developing a greater understanding of the maladaptations associated with a previous insult is important. Despite continual research over the past decade, recurrence rates have not declined suggesting the aetiology of re-injury is still not well understood. Whilst non-modifiable risk factors (e.g. increasing age and previous injury history) have been implicated in the incidence of first time and recurrent injuries, there are still a number of modifiable risk factors that are yet to be examined in detail in the scientific literature. One such factor hypothesized to influence the risk of HSI is the architectural characteristics of the biceps femoris long head (BFlh). The primary aim of this thesis was to explore the association between BFlh architecture and the aetiology of HSI and re-injury. If BFlh architecture was found to be associated with the occurrence and recurrence of HSI, the secondary aim of this thesis was to then determine the malleability of these architectural characteristics in response to a resistance training intervention.
Estimating the impact of the Galactic bar on the evolution of Galactic star clusters from N -body simulations

Publisher: name: Swinburne
Year: 2024

description: We present an analysis of the effect of a barred gravitational potential on the evolution of several properties of star clusters, constructing a model of the Galactic bar and evolving a set of direct N-body simulations of star clusters within the resulting potential. As a first step, we have confirmed that the Galactic bar has a negligible effect on the evolution of star clusters orbiting at distances of 4 kpc or greater from the Galactic Centre. We then performed an extensive orbital analysis in order to identify typical families of planar orbits in the inner regions of a Milky Way-like barred bulge, and followed the evolution of several structural parameters of clusters belonging to the four main orbit families that were identified. We have shown that the orbit type can strongly influence the evolution of total mass, size, core radius, internal velocity dispersion and escape rates of the simulated clusters. Mass-loss rate and dissolution time of the clusters are found to be sensitive to the tidal forcing along the different orbits. We describe a method to predict dissolution times and mass-loss rates of clusters evolving within a barred potential, following any orbit and with any initial mass. Finally, we applied our method to predict the dissolution time and to reconstruct the initial mass of two Galactic bulge clusters with known orbits, namely NGC 6553 and HP 1.

description: We show that the mass fraction of neutral atomic gas (H i and He) in isolated local disk galaxies of baryonic mass is well described by a straightforward stability model for flat exponential disks. In the outer disk parts, where gas at the characteristic dispersion of the warm neutral medium is stable in the sense of Toomre, the disk consists of neutral atomic gas; conversely, the inner part where this medium would be Toomre-unstable, is dominated by stars and molecules. Within this model, only depends on a global stability parameter , where j is the baryonic specific angular momentum of the disk and σ the velocity dispersion of the atomic gas. The analytically derived first-order solution provides a good fit to all plausible rotation curves. This model, with no free parameters, agrees remarkably well (±0.2 dex) with measurements of in isolated local disk galaxies, even with galaxies that are extremely H i-rich or H i-poor for their mass. The finding that increasing monotonically with q for pure stability reasons offers a powerful intuitive explanation for the mean variation of with : in a cold dark matter universe, galaxies are expected to follow , which implies the average scaling and hence, in agreement with the observations.
Exercise and nutrient interactions: Effects on skeletal muscle and body fat mass
Creators: name: Parr, Evelyn
Publisher: name: Australian Catholic University
Year: 2015

description: "The worldwide prevalence of overweight and obesity continues to rise and will soon place unsustainable demands on the healthcare systems of most developed nations. Sarcopenia, the age-related loss of muscle mass, is commonly exacerbated in overweight/obese individuals causing loss of function and independence. Accordingly, a critical goal for overweight/obese adults is to lose fat mass while preserving lean mass to prevent the deleterious effects of inactivity and age-related metabolic diseases. Although numerous studies have manipulated combinations of diet and/or exercise training to promote weight loss, the optimal diet to improve body composition remains controversial. Furthermore, the composition of tissue losses (i.e. fat versus lean mass) is not always examined and individual responses to weight loss interventions have, to date, received little scientific enquiry. Further, the success of a weight loss intervention should be determined not only acutely, but also in terms of its efficacy in maintaining body composition changes. This thesis comprised a series of independent but related studies that investigated the role of exercise and energy-restricted diets of varying macronutrient composition on the maintenance of skeletal muscle mass and body composition..."

Recent advances include the realisation of Bose-Einstein condensation in multiple sites of a magnetic lattice of one-dimensional microtraps, the trapping of ultracold atoms in square and triangular magnetic lattices, and the fabrication of magnetic lattice structures with sub-micron period suitable for quantum tunnelling experiments. Finally, we describe a proposal to utilise long-range interacting Rydberg atoms in a large spacing magnetic lattice to create interactions between atoms on neighbouring sites.

description: Vortex shedding in a bank of three rectangular burner-jets was investigated using a CFD model. The jets were angled to the wall and the whole burner was recessed into a cavity in the wall; the ratio of velocities between the jets varied from 1 to 3. The model was validated against experimentally measured velocity profiles and wall pressure tapings from a physical model of the same burner geometry, and was generally found to reproduce the mean flow field faithfully. The CFD model showed that vortex shedding was induced by a combination of an adverse pressure gradient, resulting from the diffuser-like geometry of the recess, and the entrainment of fluid into the spaces separating the jets. The asymmetry of the burner, a consequence of being angled to the wall, introduced a cross-stream component into the adverse pressure gradient that forced the jets to bend away from their geometric axes, the extent of which depended upon the jet velocity. The vortex shedding was also found to occur in different jets depending on the jet velocity ratio.
Exploring the breast care nurse role in supporting women with breast cancer
Creators: name: Ahern, Tracey
Publisher: name: Australian Catholic University
Year: 2015

description: Breast cancer is the most common female cancer worldwide and the incidence is increasing. Due to advances in diagnosis and treatment, the number of women surviving breast cancer is also increasing. Those living with and beyond a breast cancer diagnosis need access to a wide variety of information and support which may vary depending on their circumstances. Breast care nurses (BCNs) are well recognised by Australian breast cancer patients for the information and support they provide. However, even though the BCN role has existed within the Australian healthcare system since the 1990’s very little national research has reported on their role, including their different geographical work contexts. The Professional Navigation Framework, used in Canada, provided a useful theoretical framework to inform exploration of these gaps in service to breast cancer patients.
Reconceptualising the preservation of special character in Catholic secondary schools: An investigation of the role of the Director of Religions Studies in Catholic secondary schools in the Hamilton Diocese, Aotearoa New Zealand.

description: Since the enactment of the Private Schools Conditional Integration Act in New Zealand in 1975, leadership in Catholic schools has become increasingly complex. Under the legislation Catholic schools are required to develop and maintain the special character of the school. In recent times the position of Director of Religious Studies (DRS) has become a prominent leadership position with a key responsibility to ensure the structural transmission of the special character of the school. Financial or State-aid is dependent upon each school’s ability to develop and maintain its special character. The challenges and demands placed on DRSs to develop and maintain the special character of the Catholic school has impacted perceptions of the role of the DRS to the point where it has become necessary to reconceptualise the role. This study provides insights into the central responsibilities and characteristics of the DRS which are vital to any considerations pertaining to reconceptualising the DRS role for contemporary leadership.
The sweetest little buggers: Exploitation to autonomy in representations of the Botswana San
Creators: name: Thomas, Roie
Publisher: name: Australian Catholic University
Year: 2016

description: "This study draws on postcolonial and post-tourism theories to explore tourism representations of the San (commonly known outside Africa as Bushmen); predominantly those who traditionally occupied the Central Kalahari region of Botswana. This thesis deploys images, articles and captions from tourist publications, tourist ’blogs, an academic documentary, the film The Gods Must Be Crazy (1980), literary texts such as selected works of Laurens van der Post, and Alexander McCall Smith’s (1998 –) No.1 Ladies’ Detective Agency series as well as a series of artistic self-representations. These texts demonstrate tangible evidence of the role of representation in disenfranchisement and an increasing autonomy in the case of the San. Obviously a direct causal link between representation and disempowerment, and its opposite dynamic: self-representation and empowerment, cannot be proven (that is, measured) substantively but the two correlations are, I assert, sufficiently axiomatic. The data qualitatively analysed in Chapters Three and Four are tourism texts comprising representations of the San, created without their authorisation. Data are accessed interpretively through public-domain representations that show the capacity of tourist texts to perpetuate or challenge the position of the Indigenous people in this context. The texts deconstructed in this thesis depict the San of the Central Kalahari region of Botswana in a variety of ways, designed either for tourist consumption specifically, with the imagery and rhetoric directly addressing them, or for commercial distribution, where tourists have been enticed to Botswana via incidental representations within such texts. Incorporated within the analysis of some texts are comments from recently posted tourist ’blogs, substantiating the fact that the rhetoric and imagery of the representations have, generally, precisely the effect upon tourists they were designed to have. Following the analysis of non San-authorised representations, San self-representations for tourist consumption are shown (Chapter Five) as relatively recent exemplars of a burgeoning self-determination and, in fact, resistance to the Tswana hegemony operating in Botswana. Postcolonial theory is the framework underpinning the analysis of representations of the Botswana San produced for tourist consumption. Postcolonial analysis will be informed and supported by a post-tourism paradigm, that is, a critique of cultural tourism’s traditionally exploitative and paternalistic assumptions and practices as well as the awareness of the ‘blurring between fact and fiction, reality and fantasy, education and entertainment’ that characterises the tourism domain (Sherlock, 2001: 282). This thesis analyses tourism industry representations of the San people of Botswana predominantly using David Spurr’s categories of colonial (and neo-colonial) thought and practice identified in The Rhetoric of Empire (1993)."

description: We present the Dark-ages Reionization and Galaxy formation Observables from Numerical Simulations (DRAGONS) programme and Tiamat, the collisionless N-body simulation programme upon which DRAGONS is built. The primary trait distinguishing Tiamat from other large simulation programme is its density of outputs at high redshift (100 from z = 35 to z = 5; roughly one every 10 Myr) enabling the construction of very accurate merger trees at an epoch when galaxy formation is rapid and mergers extremely frequent. We find that the friends-of-friends halo mass function agrees well with the prediction of Watson et al. at high masses, but deviates at low masses, perhaps due to our use of a different halo finder or perhaps indicating a break from ‘universal’ behaviour. We then analyse the dynamical evolution of galaxies during the Epoch of Reionization finding that only a small fraction (∼20 per cent) of galactic haloes are relaxed. We illustrate this using standard relaxation metrics to establish two dynamical recovery time-scales: (i) haloes need ∼1.5 dynamical times following formation, and (ii) ∼2 dynamical times following a major (3:1) or minor (10:1) merger to be relaxed. This is remarkably consistent across a wide mass range. Lastly, we use a phase-space halo finder to illustrate that major mergers drive long-lived massive phase-space structures which take many dynamical times to dissipate. This can yield significant differences in the inferred mass build-up of galactic haloes and we suggest that care must be taken to ensure a physically meaningful match between the galaxy formation physics of semi-analytic models and the halo finders supplying their input.

description: Surface nanostructures have shown potential as biomaterials, in tissue engineering and regenerative medicine devices since they have been shown to enhance cellular function by modulating cell-surface interactions in a controlled manner. This work studies human stem cell behavior on titanium dioxide (TiO2) nanotubes that were fabricated on nano-grained (NG) and coarse-grained (CG) substrates. The NG substrates were derived by surface mechanical attrition treatment (SMAT), which has the advantage of being simple to implement. The TiO2 nanotube layer formed on the SMATed titanium (Ti) is thicker and has an inner diameter (70 nm) greater than a comparable layer observed on an untreated (40 nm) substrate. The results illustrate that a NG Ti layer favors the growth of TiO2 nanotubes; presumably due to the high density of grain boundaries and dislocations. An increase in adhesion of human mesenchymal stem cells (hMSCs) in short term culture was observed on the TiO2 nanotubes grown on the NG substrate compared to those grown on the CG substrate, which we attribute to the various roughness and hydrophilicity differences between the two surfaces. Additionally, higher specific strengths of the TiO2 nanotubes may also be achieved by taking advantage of the Ti grain changes on the substrate and the subsequent growth of the nanotubes. Furthermore, structural deformations at the nanoscale can be exploited to manufacture advanced biomaterial surfaces that are designed to enable improved stem cell attachment.

description: Observations of debris disks offer a window into the physical and dynamical properties of planetesimals in extrasolar systems through the size distribution of dust grains. In particular, the millimeter spectral index of thermal dust emission encodes information on the grain size distribution. We have made new VLA observations of a sample of seven nearby debris disks at 9 mm, with 3" resolution and ~5 μJy beam−1rms. We combine these with archival ATCA observations of eight additional debris disks observed at 7 mm, together with up-to-date observations of all disks at (sub)millimeter wavelengths from the literature, to place tight constraints on the millimeter spectral indices and thus grain size distributions. The analysis gives a weighted mean for the slope of the power-law grain size distribution, n(a) x {a}-q, of (q) =3.36 ± 0.02, with a possible trend of decreasing q for later spectral type stars. We compare our results to a range of theoretical models of collisional cascades, from the standard self-similar, steady-state size distribution (q = 3.5) to solutions that incorporate more realistic physics such as alternative velocity distributions and material strengths, the possibility of a cutoff at small dust sizes from radiation pressure, and results from detailed dynamical calculations of specific disks. Such effects can lead to size distributions consistent with the data, and plausibly the observed scatter in spectral indices. For the AU Mic system, the VLA observations show clear evidence of a highly variable stellar emission component; this stellar activity obviates the need to invoke the presence of an asteroid belt to explain the previously reported compact millimeter source in this system.

description: We use high-resolution N-body simulations to study the concentration and spin parameters of dark matter haloes in the mass range 108 M⊙ h−1 < M < 1011 M⊙ h−1 and redshifts 5 < z < 10, corresponding to the haloes of galaxies thought to be responsible for reionization. We build a subsample of equilibrium haloes and contrast their properties to the full population that also includes unrelaxed systems. Concentrations are calculated by fitting both NFW and Einasto profiles to the spherically averaged density profiles of individual haloes. After removing haloes that are out of equilibrium, we find a z > 5 concentration–mass (c(M)) relation that is almost flat and well described by a simple power law for both NFW and Einasto fits. The intrinsic scatter around the mean relation is Δcvir ∼ 1 (or 20 per cent) at z = 5. We also find that the analytic model proposed by Ludlow et al. reproduces the mass and redshift dependence of halo concentrations. Our best-fitting Einasto shape parameter, α, depends on peak height, ν, in a manner that is accurately described by α = 0.0070ν2 + 0.1839. The distribution of the spin parameter, λ, has a weak dependence on equilibrium state; λ peaks at roughly ∼0.033 for our relaxed sample, and at ∼0.04 for the full population. The spin–virial mass relation has a mild negative correlation at high redshift.
Quantifying the (X/peanut)-shaped structure in edge-on disc galaxies: length, strength, and nested peanuts

description: X-shaped or peanut-shaped (X/P) bulges are observed in more than 40 per cent of (nearly) edge-on disc galaxies, though to date a robust method to quantify them is lacking. Using Fourier harmonics to describe the deviation of galaxy isophotes from ellipses, we demonstrate with a sample of 11 such galaxies (including NGC 128) that the sixth Fourier component (B6) carries physical meaning by tracing this X/P structure. We introduce five quantitative diagnostics based on the radial B6 profile, namely: its ‘peak’ amplitude (Πmax); the (projected major-axis) 'length' where this peak occurs (RΠ, max); its vertical ‘height’ above the disc plane (zΠ, max); a measure of the B6 profile's integrated ‘strength’ (SΠ); and the B6 peak ‘width’ (WΠ). We also introduce different ‘classes’ of B6 profile shape. Furthermore, we convincingly detect and measure the properties of multiple (nested) X/P structures in individual galaxies which additionally display the signatures of multiple bars in their surface brightness profiles, thus consolidating further the scenario in which peanuts are associated with bars. We reveal that the peanut parameter space ('length', 'strength' and 'height') for real galaxies is not randomly populated, but the three metrics are inter-correlated (both in kpc and disc scalelength h). Additionally, the X/P 'length' and 'strength' appear to correlate with (vrot/σ⋆), lending further support to the notion that peanuts ‘know’ about the galactic disc in which they reside. Such constraints are important for numerical simulations, as they provide a direct link between peanuts and their host disc. Our diagnostics reveal a spectrum of X/P properties and could provide a means of distinguishing between different peanut formation scenarios discussed in the literature. Moreover, nested peanuts, as remnants of bar buckling events, can provide insights into the disc and bar instability history.

Manual accounting involves the recording of their business’ financial information and transactions, in which orders, invoices, expenses, and bank reconciliation are maintained using Microsoft Excel Spreadsheets to store, classify and analyze financial transactions of the company [1]. This project introduces a system to the company that converts their manual accounting process to a centralized financial management system. The system is developed to improve their accounting process to a faster, efficient and accurate account reporting. The Agile Method is the method used by the researchers in order to properly manage the activities and system functionalities.

description: We present an accurate and fast framework for generating mock catalogues including low-mass haloes, based on an implementation of the COmoving Lagrangian Acceleration (COLA) technique. Multiple realisations of mock catalogues are crucial for analyses of large-scale structure, but conventional N-body simulations are too computationally expensive for the production of thousands of realizations. We show that COLA simulations can produce accurate mock catalogues with a moderate computation resource for low- to intermediate-mass galaxies in 1012 M⊙ haloes, both in real and redshift space. COLA simulations have accurate peculiar velocities, without systematic errors in the velocity power spectra for k ≤ 0.15 h Mpc−1, and with only 3-per cent error for k ≤ 0.2 h Mpc−1. We use COLA with 10 time steps and a Halo Occupation Distribution to produce 600 mock galaxy catalogues of the WiggleZ Dark Energy Survey. Our parallelized code for efficient generation of accurate halo catalogues is publicly available at github.com/junkoda/cola_halo.

description: Infrapatellar fat pad adipose stem cells (IPFP-ASCs) have been shown to harbor chondrogenic potential. When combined with 3D polymeric structures, the stem cells provide a source of stem cells to engineer 3D tissues for cartilage repair. In this study, we have shown human IPFP-ASCs seeded onto 3D printed chitosan scaffolds can undergo chondrogenesis using TGFβ3 and BMP6. By week 4, a pearlescent, cartilage-like matrix had formed that penetrated the top layers of the chitosan scaffold forming a 'cap' on the scaffold. Chondrocytic morphology showed typical cells encased in extracellular matrix which stained positively with toluidine blue. Immunohistochemistry demonstrated positive staining for collagen type II and cartilage proteoglycans, as well as collagen type I. Real time PCR analysis showed up-regulation of collagen type II, aggrecan and SOX9 genes when IPFP-ASCs were stimulated by TGFβ3 and BMP6. Thus, IPFP-ASCs can successfully undergo chondrogenesis using TGFβ3 and BMP6 and the cartilage-like tissue that forms on the surface of 3D-printed chitosan scaffold may prove useful as an osteochondral graft. © 2014 Ye et al.

description: Using Silica Sulfuric Acid (SSA) as an eco-friendly, readily available, and reusable catalyst, herein we were prepared a new series of 3,4-dihydropyrimidin-2-(1H)ones and -thiones 4–16 (DHMPs). The condensation reaction of 2,5-dimethoxybenzaldehyde, 1,3-diphenylpropane-1,3-dione, and thiourea as one-pot reaction (known as Biginelli reaction) by using different catalysts. Silica sulfuric acid (SSA) showed the best catalytic activity (with yield 99%) using 0.11 mol at 15 min in the presence of ethylene glycol as green solvent. The targeted compounds of 3,4-dihydropyrimidin-2-(1H)ones and -thiones 4–16 have been fully characterized and tested as novel anti-cancer agents. The biological activity of the synthesized compounds 4–16, were evaluated in vitro as anti-cancer agents against both liver (Huh7 cell line) and lung cancer (A549) cells. Most of the tested compounds showed potential cytotoxic activity against liver cancer (Huh7) cell line, while they had moderate to week cytotoxic activity against lung cancer (A549) cell line. Most notably, compound 13 was the most effective cytotoxic agent against both liver and lung cancer cell lines, with less toxicity against non-cancer cell line MDCK, when compared to Doxorubicin as reference drug. Therefore, the mode of action of this compound using flow cytometry and molecular docking was investigated. The SAR study showed that the pyrimidines that contains chloride, florid or methoxy groups in their structures gave potent anti-cancer activity than that contains phenyl or naphthalene moieties, while the presence of sulfur as a substitution on the pyrimidine ring increased the anti-cancer activity than that observed in the presence of oxygen.

description: A primary goal of cognitive behavior therapy for psychosis (CBTp) is to reduce distress and disability, not to change the positive symptoms of psychosis, such as hearing voices. Despite demonstrated associations between beliefs about voices and distress, the effects of CBTp on reducing voice distress are disappointing. Research has begun to explore the role that the psychological construct of 'self' (which includes numerous facets such as self-reflection, self-schema and self-concept) might play in causing and maintaining distress and disability in voice hearers. However, attempts to clarify and integrate these different perspectives within the voice hearing literature, or to explore their clinical implications, are still in their infancy. This paper outlines how the self has been conceptualised in the psychosis and CBT literatures, followed by a review of the evidence regarding the proposed role of this construct in the etiology of and adaptation to voice hearing experiences. We go on to discuss some of the specific intervention methods that aim to target these aspects of self-experience and end by identifying key research questions in this area. Notably, we suggest that interventions specifically targeting aspects of self-experience, including self-affection, self-reflection, self-schema and self-concept, may be sufficient to reduce distress and disruption in the context of hearing voices, a suggestion that now requires further empirical investigation.
Aerodynamics of loose sports garments

description: Ski Cross rules require loose garments and skin suits are not allowed. This study investigated the aerodynamic behaviour of flapping garments of different looseness ratios (garment length to cylinder circumference) mounted on a horizontal cylinder. Three fabrics of different roughness were tested in a wind tunnel from 20 to 140 kph. Tight fitting textiles showed the standard flow transition and critical flow regime known from smooth and rough cylinders. Flapping textiles exhibited a higher drag coefficient (on average 1.5 times higher than the tight fitting fabrics in the subcritical regime), which decreased slightly with speed. The high drag coefficient can be attributed to the flutter amplitude which increases the wake diameter and prevents backward movement of the separation points. The looseness ratio (fineness ratio) affects the drag coefficient only marginally (drag decreases with the ratios).

description: Falls risk increases with ageing but is substantially higher in people with stroke. Tripping-related balance loss is the primary cause of falls, and Minimum Toe Clearance (MTC) during walking is closely linked to tripping risk. The aim of this study was to determine whether real-time augmented information of toe-ground clearance at MTC can increase toe clearance, and reduce tripping risk. Nine healthy older adults (76 ± 9 years) and one 71 year old female stroke patient participated. Vertical toe displacement was displayed in real-time such that participants could adjust their toe clearance during treadmill walking. Participants undertook a session of unconstrained walking (no-feedback baseline) and, in a subsequent Feedback condition, were asked to modify their swing phase trajectory to match a "target" increased MTC. Tripping probability (PT) pre- and post-training was calculated by modeling MTC distributions. Older adults showed significantly higher mean MTC for the post-training retention session (27.7 ± 3.79 mm) compared to the normal walking trial (14.1 ± 8.3 mm). The PT on a 1 cm obstacle for the older adults reduced from 1 in 578 strides to 1 in 105,988 strides. With gait training the stroke patient increased MTC and reduced variability (baseline 16 ± 12 mm, post-training 24 ± 8 mm) which reduced obstacle contact probability from 1 in 3 strides in baseline to 1 in 161 strides post-training. The findings confirm that concurrent visual feedback of a lower limb kinematic gait parameter is effective in changing foot trajectory control and reducing tripping probability in older adults. There is potential for further investigation of augmented feedback training across a range of gait-impaired populations, such as stroke. © 2014 Begg, Tirosh, Said, Sparrow, Steinberg, Levinger and Galea.
