description: We take advantage of a state-of-art semi analytic model of galaxy formation, and the model presented in \citet{contini21a}, to investigate the mass distribution of Brightest Cluster Galaxies (BCGs) and Intra-Cluster Light (ICL) by addressing two points: (1) the region of transition between a BCG dominated distribution and an ICL dominated one, and; (2) the relation between the total BCG+ICL mass and the ICL one alone. We find the transition radius to be independent of both BCG+ICL and halo masses, with an average of 60$\pm$40 kpc, in good agreement with previous observational measurements, but given the large scatter, it can be considered as a sort of physical separation between the two components only on cluster scale. From the analysis of $M_{ICL}-M_{BCG+ICL}$ relation, we build a method able to extract the ICL mass directly from the knowledge of the BCG+ICL one. Given the large scatter on low mass systems, such method under/overpredicts the true value of the ICL in a significant way, up to a factor of three in the worst cases. On the other hand, for $\log M_{BCG+ICL}>12$ or $\log M_{Halo}>14$, the difference between the true value and the one extracted from the $M_{ICL}-M_{BCG+ICL}$ relation ranges between $\pm$30\%. We therefore suggest this relation as a reliable test for observational works aiming to isolate the ICL from the BCG, for systems hosted by haloes on cluster scale.

description: Critical discourse analysis investigates the ways in which discourse is to abuse power relationships. Political debates constitute discourses that mirror certain aspects of ideologies. This study aimed to uncover the ideological intentions in the formulation and circulation of hegemonic political ideology in TV political debates that occurred in the 2011-2012 Yemen revolution, examining the question of how ideology was used as a tool of hegemony. The corpus of the study consisted of fifteen debates (73915 words) from four live debate programmes (The Opposite Direction, In Depth, Behind the News and the Revolution Talk) staged at Al Jazeera Arabic TV channel between 2011 and 2012. Al Jazeera was selected as the focus of this study because of its position as the most popular TV in the Arab world and due to its strong presence during the Arab revolutions. Two debate sides were identified: government, representing the president Ali Abdullah Saleh and his regime, and protesters, who represented the discontent populace gathering squares who demanded the abdication of the president. Data were also obtained from interviews conducted with the Al Jazeera staff who managed the debates. Analysis was conducted on the verbal discourse aspects of four debates, one debate from each programme, using critical discourse analysis: aspects from the van Leeuwen’s (2008, 2009) Social Actor Network model, supplemented by additional linguistic features. The results were triangulated using computer-assisted corpus analysis for the entire corpus, the fifteen debates. AntConc (version 3.2.4w) was used to process the keyword lists, word concordances and collocations. The results of the analysis were then compared with the interviews with AJ staff. The main research finding was that although results of the critical discourse analysis correlated with those of the computer-assisted corpus analysis, they differed to a marked degree from the perceptions of Al Jazeera staff. Also, evident is that Al Jazeera and the protesters had similar ideological intentions, including glorifying the revolution and inciting protests, which was not the case with the government speakers. Overall, the findings show that Al Jazeera displayed evident bias, excluding the government from its debates in a way that runs counter to its mission statement and the tenets of objective journalism. The findings of this study illustrate the powerful role that language plays in shaping ideological media intentions and influencing the media audience.

description: The role of inducible nitric oxide synthase (iNOS) and/or nitric oxide (NO) in atherosclerosis remains elusive. Several researchers argued whether iNOS and/or NO are pathogenic or cardio protective. The pathogenesis of atherosclerosis is complex and includes mechanisms associated with inducible nitric oxide synthase (iNOS). We have demonstrated that the expression and function of iNOS may be selectively down regulated by pro-oxidants such as antimycin A and diethyl maleate (DEM). To further explore the underlying mechanisms associated with these effects we have investigated whether antimycin A and/or DEM modulated the activation of key cellular signalling molecules associated with the induction of iNOS. Expression of p38 mitogen activated kinase (MAPK) and Akt were induced by exposure to lipopolysaccharide (LPS) and interferon-gamma (IFN-). Oxidative stress (OS) was induced using antimycin A, DEM and hydrogen peroxide (H2O2). All three OS inducers caused a significant generation of free radicals whereas only antimycin A and DEM generated superoxide radical (O2-). Also nitrite production and iNOS expression may be down regulated, in part; by pro-oxidants generating O2- but not hydroxyl radicals (OH-). Antimycin A and DEM concentration dependently inhibited the phosphorylation of p38 MAPK and Akt and this was restored when the cells were pre-treated with Atorvastatin whereas H2O2 was without any significant effect. Taken together, the data suggest novel actions for both pro-oxidants and atorvastatin which may have important implications in coronary artery disease where suppression of iNOS may be deleterious and maintaining its expression may be cardio-protective.

description: Rationale and Aims: Research into the lived experience of parenting children with muscular dystrophy has typically addressed key transitions along the disease trajectory, such as diagnosis or end-of-life care. Families reportedly face continuous challenges as their child’s health deteriorates. No research has considered accounts of parenting across the lifespan that look at adaptation following their child’s death. This research was conducted in the context of a wish-fulfilment charity that offer experiences for children to be supported in activities that are usually deemed inaccessible. In this context, the study asked how do parents who have lost a child to muscular dystrophy story their experiences of parenting. Methods: This research used a qualitative approach that explored the accounts of eight parents interviewed in couples, all of who had experienced the death of their child to muscular dystrophy. The study used a semi-structured interview, lasting from 100-150 minutes each. Interviews were video-recorded, transcribed, and analysed using narrative analysis to explore what and how the parents narrated their experiences. Consideration was given to the social and cultural contexts that shaped these. Analysis: Multiple readings of the transcripts allowed me to develop individual summaries and then construct an analysis across all of the accounts. Three main stories of change, survival and creating change emerged through my analysis. These three stories represented six sub-stories in total: waking up to different futures; being so close, you don’t see the deterioration; humour through the struggle; storytelling together; creating a legacy; and living the dream. Findings: Couples narrated the loss of parental dreams, leading to the need for identity (re)formation. Humour and storytelling together were often used to regulate emotions during the storying telling, and a means of surviving their loss. Parents shared narratives of building legacies and the memories created through ‘living the dream’, which alluded to an impact that surpassed death itself. Implications: These findings suggest the need for greater consideration of sense-making, changing identities, and benefit-finding in clinical consultations, at key transitions during the parenting journey and particularly following the death of a child to muscular dystrophy. Accounts suggest that wish-fulfilment events can sustain hope for parents, a proposition that will need further investigation in the future.

description: The acceleration of charged particles by interplanetary shocks (IPs) can drain a non-negligible fraction of the plasma pressure. In this study, we have selected 17 IPs observed in-situ at $1\,\text{au}$ by the Advanced Composition Explorer (ACE) and the Wind spacecraft, and 1 shock at $0.8\,\text{au}$ observed by Parker Solar Probe (PSP). We have calculated the time-dependent partial pressure of supra-thermal and energetic particles (smaller and greater than $50\,\text{keV}$ for protons and $30\,\text{keV}$ for electrons, respectively) in both the upstream and downstream regions. The particle fluxes were averaged for 1 hour before and 1 hour after the shock time to remove short time scale effects. Using the MHD Rankine-Hugoniot jump conditions, we find that the fraction of the total upstream energy flux transferred to supra-thermal and energetic downstream particles is typically $\lesssim\!16\%$, in agreement with previous observations and simulations. Notably, by accounting for errors on all measured shock parameters, we have found that for any given fast magnetosonic Mach number, $M_{f}\!<7$, the angle between the shock normal and average upstream magnetic field, $θ_{Bn}$, is not correlated with the energetic particle pressure; in particular, the partial pressure of energized particles does not decrease for $θ_{Bn} \gtrsim 45^\circ$. The downstream electron-to-proton energy ratio in the range $\gtrsim\!140\,\text{eV}$ for electrons and $\gtrsim\!70\,\text{keV}$ for protons exceeds the expected $\sim\!1\%$ and nears equipartition ($>\!0.1$) for the Wind events.

description: This study calculated astrophysical parameters, as well as kinematic and galactic orbital parameters, of the open clusters NGC 1664 and NGC 6939. The work is based on CCD UBV and Gaia photometric and astrometric data from ground and space-based observations. Considering Gaia Early Data Release 3 (EDR3) astrometric data, we determined membership probabilities of stars located in both of the clusters. We used two-color diagrams to determine $E(B-V)$ color excesses for NGC 1664 and NGC 6939 as $0.190 \pm 0.018$ and $0.380 \pm 0.025$ mag, respectively. Photometric metallicities for the two clusters were estimated as [Fe/H] = $-0.10 \pm 0.02$ dex for NGC 1664 and as [Fe/H] = $-0.06 \pm 0.01$ dex for NGC 6939. Using the reddening and metallicity calculated in the study, we obtained distance moduli and ages of the clusters by fitting PARSEC isochrones to the color-magnitude diagrams based on the most likely member stars. Isochrone fitting distances are $1289 \pm 47$ pc and $1716 \pm 87$ pc, which coincide with ages of $675 \pm 50$ Myr and $1.5 \pm 0.2$ Gyr for NGC 1664 and NGC 6939, respectively. We also derived the distances to the clusters using Gaia trigonometric parallaxes and compared these estimates with the literature. We concluded that the results are in good agreement with those given by the current study. Present day mass function slopes were calculated as $Γ=-1.22\pm0.33$ and $Γ=-1.18\pm0.21$ for NGC 1664 and NGC 6939, respectively, which are compatible with the Salpeter (1955) slope. Analyses showed that both of clusters are dynamically relaxed. The kinematic and dynamic orbital parameters of the clusters were calculated, indicating that the birthplaces of the clusters are outside the solar circle.

description: BACKGROUND: Prospective memory difficulties are one of the most common deficits following acquired brain injury. The application of smartphones as a compensatory aid to these difficulties has shown promising results. This study looked to investigate these benefits further. OBJECTIVE: The aims of this study were to investigate whether receipt of reminder prompts through ones smartphone improved completion of pre-planned tasks, in addition to whether it also had secondary implications for participant’s wellbeing, confidence, independent functioning, and whether it had any impact on caregiver strain levels. METHOD: This study used an ABAB case series design with mild to moderate acquired brain injury. Task completion rates were monitored across four phases (prompts vs. no prompts). Quantitative questionnaires were administered pre, post and at three months follow up to assess coping with memory difficulties. A qualitative questionnaire explored the perceived impact of the smartphone reminders on everyday functioning, in addition to a 3 month follow up measure assessing attrition rates in smartphone use. RESULTS: Visual inspection analysis suggested greater task completion when reminders were provided. The quantitative questionnaires showed increased use of a Smartphone as reminder device post intervention and at follow up. A basic thematic analysis highlighted a perception that the smartphone system increased task completion, confidence in coping with memory demands, supported emotional wellbeing and reduced dependence on others. As a memory aid it was also less stigmatising and promoted dignity. The three month follow up questionnaire highlighted that all participants continued to use their smartphone as a memory aid. CONCLUSIONS: Use of a smartphone as a memory compensation aid may improve completion of pre-set tasks. Secondary benefits may include increased confidence in coping with memory demands, reduced dependence on others for help, and reduced anxiety or frustration around forgetting.

description: We calculated the electron-positron pair production rate at the base of the jet of 3C 120 by collisions of photons from the hot accretion flow using the measurement of its average soft gamma-ray spectrum by Compton Gamma Ray Observatory. We found that this rate approximately equals the flow rate of the leptons emitting the observed synchrotron radio-to-IR spectrum of the jet core, calculated using the extended jet model following Blandford \& Konigl. This coincidence shows the jet composition is likely to be pair-dominated. We then calculated the jet power in the bulk motion of ions, and found it greatly exceeds that achievable by the magnetically arrested disk scenario for the maximum black hole spin unless the jet contains mostly pairs. Next, we found that the magnetic flux through the synchrotron-emitting jet equals the maximum poloidal flux that can thread the black hole. Finally, we compared two estimates of the magnetization parameter at the onset of the synchrotron emission and found they are in agreement only if pairs dominate the jet content.

description: Magnetic skyrmions are chiral nanoscale spin textures which are usually induced by Dzyaloshinskii-Moriya interaction (DMI). Recently, magnetic skyrmions have been observed in two-dimensional (2D) van der Waals (vdW) ferromagnetic materials, such as Fe$_{3}$GeTe$_{2}$. The electric control of skyrmions is important for their potential application in low-power memory technologies. Here, we predict that DMI and magnetic skyrmions in a Fe$_{3}$GeTe$_{2}$ monolayer can be controlled by ferroelectric polarization of an adjacent 2D vdW ferroelectric In$_{2}$Se$_{3}$. Based on density functional theory and atomistic spin-dynamics modeling, we find that the interfacial symmetry breaking produces a sizable DMI in a Fe$_{3}$GeTe$_{2}$/In$_{2}$Se$_{3}$ vdW heterostructure. We show that the magnitude of DMI can be controlled by ferroe-lectric polarization reversal, leading to creation and annihilation of skyrmions. Furthermore, we find that the sign of DMI in a In$_{2}$Se$_{3}$/Fe$_{3}$GeTe$_{2}$/In$_{2}$Se$_{3}$ heterostructure changes with ferroelectric switching reversing the skyrmion chirality. The predicted electrically controlled skyrmion formation may be interesting for spintronic applications.

description: Chirality and topology are intimately related fundamental concepts, which are heavily explored to establish spin-textures as potential magnetic bits in information technology. However, this ambition is inhibited since electrical reading of chiral attributes is highly non-trivial with conventional current perpendicular-to-plane (CPP) sensing devices. Here we demonstrate from extensive first-principles simulations and multiple scattering expansion the emergence of the chiral spin-mixing magnetoresistance (C-XMR) enabling highly efficient all-electrical readout of the chirality and helicity of respectively one- and two-dimensional magnetic states of matter. It is linear with spin-orbit coupling in contrast to the quadratic dependence associated with the newly unveiled non-local spin-mixing anisotropic MR (X-AMR). Such transport effects are systematised on various non-collinear magnetic states -- spin-spirals and skyrmions -- and compared to the uncovered spin-orbit-independent multi-site magnetoresistances. Owing to their simple implementation in readily available reading devices, the proposed magnetoresistances offer exciting and decisive ingredients to explore with all-electrical means the rich physics of topological and chiral magnetic objects.

description: The Compton Spectrometer and Imager (COSI) is a balloon-borne compact Compton telescope designed to survey the 0.2-5 MeV sky. COSI's energy resolution of $\sim$0.2% at 1.8 MeV, single-photon reconstruction, and wide field of view make it capable of studying astrophysical nuclear lines, particularly the 1809 keV $γ$-ray line from decaying Galactic $^{26}$Al. Most $^{26}$Al originates in massive stars and core-collapse supernova nucleosynthesis, but the path from stellar evolution models to Galaxy-wide emission remains unconstrained. In 2016, COSI had a successful 46-day flight on a NASA superpressure balloon. Here, we detail the first search for the 1809 keV $^{26}$Al line in the COSI 2016 balloon flight using a maximum likelihood analysis. We find a Galactic $^{26}$Al flux of $(8.6 \pm 2.5) \times 10^{-4}$ ph cm$^{-2}$ s$^{-1}$ within the Inner Galaxy ($|\ell| \leq 30^{\circ}$, $|b| \leq 10^{\circ}$) with 3.7$σ$ significance above background. Within uncertainties, this flux is consistent with expectations from previous measurements by SPI and COMPTEL. This analysis demonstrates COSI's powerful capabilities for studies of $γ$-ray lines and underscores the scientific potential of future compact Compton telescopes. In particular, the next iteration of COSI as a NASA Small Explorer satellite has recently been approved for launch in 2025.

description: The spin-orbit coupling (SOC) is a key to understand the magnetically driven superconductivity in iron-based superconductors, where both local and itinerant electrons are present and the orbital angular momentum is not completely quenched. Here, we report a neutron scattering study on the bilayer compound CaK(Fe$_{0.96}$Ni$_{0.04}$)$_4$As$_4$ with superconductivity coexisting with a non-collinear spin-vortex crystal magnetic order that preserves the tetragonal symmetry of Fe-Fe plane. In the superconducting state, two spin resonance modes with odd and even $L$ symmetries due to the bilayer coupling are found similar to the undoped compound CaKFe$_4$As$_4$ but at lower energies. Polarization analysis reveals that the odd mode is $c-$axis polarized, and the low-energy spin anisotropy can persist to the paramagnetic phase at high temperature, which closely resembles other systems with in-plane collinear and $c-$axis biaxial magnetic orders. These results provide the missing piece of the puzzle on the SOC effect in iron-pnictide superconductors, and also establish a common picture of $c-$axis preferred magnetic excitations below $T_c$ regardless of the details of magnetic pattern or lattice symmetry.

description: This thesis investigates the role of representations and intersubjectivity in explaining pretend play of young children. Its goal is to show that basic forms of pretending can be explained without recourse to mental representations. The thesis targets two aspects of pretence: imagining (underlying the ability to act as if), and guiding (underlying the ability to play in specific ways). It proposes an alternative account of pretence to cognitivist accounts that dominate in the literature. The alternative account is based on enactivism; it proposes to explain pretending through dynamic interactions of environmental affordances and animal effectivities in context. The thesis emphasises the role of social and environmental factors as well as cultural engagements in shaping the relevant context for pretence to occur. The thesis is an important contribution both to the literature on pretence as well as to philosophy of mind. While the topic of pretence is narrow, considering it through enactive lens involves considering some of the most debated issues, such as the applicability of mechanistic explanations to studying cognition.

description: We present the most complete emission spectrum for inflated hot Jupiter HAT-P-41b combining new HST WFC/G141 spectrum from the Hubble Panchromatic Comparative Exoplanet Treasury (PanCET) program with archival Spitzer eclipse observations. We found a near blackbody-like emission spectrum which is best fitted with an isothermal temperature-pressure (TP) profile that agrees well with the dayside heat redistribution scenario assuming zero Bond albedo. The non-inverted TP profile is consistent with the non-detection of NUV/optical absorbers in the transit spectra. We do not find any evidence for significant H$^-$ opacity nor a metal-rich atmosphere. HAT-P-41b is an ideal target that sits in the transitioning parameter space between hot and ultra-hot Jupiters, and future JWST observations will help us to better constrain the thermal structure and chemical composition.

description: We report results of observations of the GGD12-15 region, where cluster formation is actively taking place, using various molecular emission lines. The C18O (J= 1-0) emission line reveals a massive clump in the region with a mass of ~2800 Mo distributed over ~2 pc. The distribution of the C18O(J= 3-2) emission is similar to that of a star cluster forming therein, with an elliptical shape of ~1 pc in size. A bipolar molecular outflow driven by IRS 9Mc, a constituent star of the cluster, is blowing in a direction perpendicular to the elongated C18O (J= 3-2) distribution, covering the entire clump. There is a massive core with a radius of 0.3 pc and a mass of 530 Mo in the center of the clump. There are two velocity components around the core, which are prominent in a position-velocity (PV) diagram along the major axis of the clump. In addition, a PV diagram along the minor axis of the clump, which is parallel to the outflow, shows a velocity gradient opposite to that of the outflow. The velocity structure strongly indicates the infalling motion of the clump. Comparison of the observational data with a simple model of infalling oblate clumps indicates that the clump is undergoing gravitational contraction with rotation.

description: Segmentation of curvilinear structures is important in many applications, such as retinal blood vessel segmentation for early detection of vessel diseases and pavement crack segmentation for road condition evaluation and maintenance. Currently, deep learning-based methods have achieved impressive performance on these tasks. Yet, most of them mainly focus on finding powerful deep architectures but ignore capturing the inherent curvilinear structure feature (e.g., the curvilinear structure is darker than the context) for a more robust representation. In consequence, the performance usually drops a lot on cross-datasets, which poses great challenges in practice. In this paper, we aim to improve the generalizability by introducing a novel local intensity order transformation (LIOT). Specifically, we transfer a gray-scale image into a contrast-invariant four-channel image based on the intensity order between each pixel and its nearby pixels along with the four (horizontal and vertical) directions. This results in a representation that preserves the inherent characteristic of the curvilinear structure while being robust to contrast changes. Cross-dataset evaluation on three retinal blood vessel segmentation datasets demonstrates that LIOT improves the generalizability of some state-of-the-art methods. Additionally, the cross-dataset evaluation between retinal blood vessel segmentation and pavement crack segmentation shows that LIOT is able to preserve the inherent characteristic of curvilinear structure with large appearance gaps. An implementation of the proposed method is available at https://github.com/TY-Shi/LIOT.

description: Ectomycorrhizal (ECM) fungi form partnerships with roughly 60% of tree species, trading nutrients, disease defense, and water for photosynthetic sugars. Different species of ECM fungi will compete for these photosynthetic sugars, and their success is highly dependent on when they colonize relative to other competitors —a phenomenon known as “priority effects”. Previous studies have shown changes in ECM fungal arrival timing are crucial in shaping ECM fungal communities. However, it is not well documented how these arrival timing changes affect plant host growth. This study aims to elucidate how different fungal arrival scenarios affect ECM fungal competitive success and host plant growth by inoculating Pinus muricata seedlings with two ECM fungal species, Rhizopogon salebrosus and Suillus pungens in different timing scenarios. S. pungens was the competitive dominant species, and consistently outcompeted R. salebrosus in all arrival timing scenarios. Both S. pungens and R. salebrosus colonized more root tips when they arrived first, underscoring the importance of priority effects in ECM fungal competition. Staggered arrival treatments, where one fungus was inoculated 31 days before the other, had similar plant growth to simultaneous co-inoculation treatments. In contrast, all combinations of two-species inoculation treatments (both staggered and co-arrival) had greater plant growth than single-species inoculation treatments, suggesting that the presence of more mutualists was more important to plant growth than arrival synchrony. These results support the idea that symbiotic diversity enhances plant host fitness, and that competition between ectomycorrhizal partners does not negatively impact the host. Overall, the findings in this project improve current understanding of how ectomycorrhizal fungal communities assemble and are relevant to developing more holistic strategies for protecting forest ecosystems.

description: We study the particle-scale motion of highly polydisperse hard disks flowing in a two-dimensional bent channel. We use various size distributions of particles, in which the largest particles are up to five times larger than the smallest. The disks are pushed through an L-shaped channel to drive the particle rearrangements. Although the mean flow is essentially independent of the polydispersity, the motion of individual particles becomes more nonaffine on average for higher polydispersity samples. We characterize the nonaffine motion, finding a qualitative difference in the behavior of small and larger particles: the smaller disks have more nonaffine motion, induced by the larger particles.

description: We report the first 3-D kinematical measurements of 88 stars in the direction of several recently discovered substructures in the southern periphery of the Large Magellanic Cloud (LMC) using a combination of Gaia proper motions and radial velocities from the APOGEE-2 survey. More specifically, we explore stars lie in assorted APOGEE-2 pointings in a region of the LMC periphery where various overdensities of stars have previously been identified in maps of stars from Gaia and DECam. By using a model of the LMC disk rotation, we find that a sizeable fraction of the APOGEE-2 stars have extreme space velocities that are distinct from, and not a simple extension of, the LMC disk. Using N-body hydrodynamical simulations of the past dynamical evolution and interaction of the LMC and Small Magellanic Cloud (SMC), we explore whether the extreme velocity stars may be accounted for as tidal debris created in the course of that interaction. We conclude that the combination of LMC and SMC debris produced from their interaction is a promising explanation, although we cannot rule out other possible origins, and that these new data should be used to constrain future simulations of the LMC-SMC interaction. We also conclude that many of the stars in the southern periphery of the LMC lie out of the LMC plane by several kpc. Given that the metallicity of these stars suggest they are likely of Magellanic origin, our results suggest that a wider exploration of the past interaction history of the Magellanic Clouds is needed.

description: We derive a relativistic field equation for the trace of the metric perturbation beyond the weak field approximation to the Einstein field equations. The dynamics is governed by a massive Klein-Gordon equation on curved space-time, where the effective mass of the field is associated with the material and the dark energy content via the cosmological term. We solve the equation in the case of a Schwarzschild black hole and show that it can be cast into an effective Schrödinger form with an effective geometric potential which binds the zero angular momentum states. The non-zero angular momentum states experience a positive potential peak before the event horizon pointing to gravitational waves scattering. Black holes scatter gravitational waves and thus we provide an unambiguous testable prediction of black hole existence. The Newtonian limit for this equation points to the possibility of reflecting gravitational waves at interfaces with sharp density boundary, thus opening up gravitational wave propulsion physics. We discuss this type of propulsion in the light of Newton's third law of Mechanics. Compelling questions such as the existence of quanta of this field which may account for the dark matter content are also addressed.

description: In this study, some plant growth regulators known as cytokinins (kinetine (K), zeatine (Z), thidiazuron (TDZ), benzylaminopurine (BAP), dimethylallylaminopurine (AAP)) were separated by HPLC using an amide-embedded mixed-mode stationary phase which was synthesized by H. Aral et al. in recent years. The effect of mobile phase content, mobile phase pH, buffer concentration and temperature on separation process was studied. In addition, a quantitative determination of cytokinins from Salvia limbata extract was studied, and some validation parameters such as limit of dedection (LOD), limit of quantification (LOQ) and relative standard deviation (RSD) were calculated as a range of 0.03-0.1, 0.1-0.26 mgL−1 and 0.03-0.08 respectively.

description: Purpose: Multipurpose robots that can perform a range of useful tasks have the potential to increase the quality of life for many people living with disabilities. Owing to factors such as high system complexity, as-yet unresolved research questions and current technology limitations, there is a need for effective strategies to coordinate the development process. Method: Integrating established methodologies based on human-centred design and universal design, a framework was formulated to coordinate the robot design process over successive iterations of prototype development. Results: An account is given of how the framework was practically applied to the problem of developing a personal service robot. Application of the framework led to the formation of several design goals which addressed a wide range of identified user needs. The resultant prototype solution, which consisted of several component elements, succeeded in demonstrating the performance stipulated by all of the proposed metrics. Conclusions: Application of the framework resulted in the development of a complex prototype that addressed many aspects of the functional and usability requirements of a personal service robot. Following the process led to several important insights which directly benefit the development of subsequent prototypes.Implications for RehabilitationThis research shows how universal design might be used to formulate usability requirements for assistive service robots.A framework is presented that guides the process of designing service robots in a human-centred way.Through practical application of the framework, a prototype robot system that addressed a range of identified user needs was developed.

description: Background: The nucleus $^{32}$Mg ($N=20$ and $Z=12$) plays a central role in the so-called "island of inversion" where in the ground states $sd$-shell neutrons are promoted to the $fp$-shell orbitals across the shell gap, resulting in the disappearance of the canonical neutron magic number $N=20$. Purpose: The primary goals of this work are to extend the level scheme of $^{32}$Mg, provide spin-parity assignments to excited states, and discuss the microscopic structure of each state through comparisons with theoretical calculations. Method: In-beam $γ$-ray spectroscopy of $^{32}$Mg was performed using two direct-reaction probes, one-neutron (two-proton) knockout reactions on $^{33}$Mg ($^{34}$Si). Final-state exclusive cross sections and parallel momentum distributions were extracted from the experimental data and compared with eikonal-based reaction model calculations combined with shell-model overlap functions. Results: Owing to the remarkable selectivity of the one-neutron and two-proton knockout reactions, a significantly updated level scheme for $^{32}$Mg, which exhibits negative-parity intruder and positive-parity normal states, was constructed. The experimental results were confronted with four different nuclear structure models. Conclusions: In some of these models, different aspects of $^{32}$Mg and the transition into the island of inversion are well described. However, unexplained discrepancies remain, and even with the help of these state-of-the-art theoretical approaches, the structure of this key nucleus is not yet fully captured.
