Realizing the analytic surgery group of Higson and Roe geometrically part II: relative η -invariants
- 2016
-

Journal article (peer-reviewed)abstract
- We apply the geometric analog of the analytic surgery group of Higson and Roe to the relative η-invariant. In particular, by solving a Baum–Douglas type index problem, we give a “geometric” proof of a result of Keswani regarding the homotopy invariance of relative η-invariants. The starting point for this work is our previous constructions in “Realizing the analytic surgery group of Higson and Roe geometrically, Part I: The geometric model”.

Co2FeAl Full Heusler Compound Based Spintronic Terahertz Emitter
- 2021
-
In: Advanced Optical Materials. - : John Wiley & Sons. - 2162-7568 .- 2195-1071. ; 9:10
-
Journal article (peer-reviewed)abstract
- To achieve a large terahertz (THz) amplitude from a spintronic THz emitter (STE), materials with 100% spin polarisation such as Co-based Heusler compounds as ferromagnetic layer are required. However, these compounds are known to loose their half-metallicity in the ultrathin film regime, as it is difficult to achieve L2(1) ordering, which has become a bottleneck for the film growth. Here, the successful deposition using room temperature DC sputtering of the L2(1) and B2 ordered phases of the Co2FeAl full Heusler compound is reported. Co2FeAl is used as ferromagnetic layer together with highly orientated Pt as nonferromagnetic layer in the Co2FeAl/Pt STE, where an MgO (10 nm) seed layer plays an important role to achieve the L2(1) and B2 ordering of Co2FeAl. The THz generation in the Co2FeAl/Pt STE is presented, which has a bandwidth of 0.2-4 THz. The THz electric field amplitude is optimized with respect to thickness, orientation, and growth parameters using a thickness dependent model considering the optically induced spin current, superdiffusive spin current, inverse spin Hall effect, and the THz attenuation in the layers. This study, based on the full Heusler Co2FeAl compound opens up a plethora of possibilities in STE research involving full Heusler compounds.

Predicting unintended effects of drugs based on off-target tissue effects
- 2016
-
In: Biochemical and Biophysical Research Communications - BBRC. - : Elsevier. - 0006-291X .- 1090-2104. ; 469:3, s. 399-404
-
Journal article (peer-reviewed)abstract
- Unintended effects of drugs can be caused by various mechanisms. Conventional analysis of unintended effects has focused on the target proteins of drugs. However, an interaction with off-target tissues of a drug might be one of the unintended effect-related mechanisms. We propose two processes to predict a drug’s unintended effects by off-target tissue effects: 1) identification of a drug’s off-target tissue and; 2) tissue protein - symptom relation identification (tissue protein - symptom matrix). Using this method, we predicted that 1,177 (10.7%) side-effects were related to off-target tissue effects in 11,041 known side-effects. Off-target tissues and unintended effects of successful repositioning drugs were also predicted. The effectiveness of relations of the proposed tissue protein - symptom matrix were evaluated by using the literature mining method. We predicted unintended effects of drugs as well as those effect-related off-target tissues. By using our prediction, we are able to reduce drug side-effects on off-target tissues and provide a chance to identify new indications of drugs of interest.

Probing effects of the SARS-CoV-2 E protein on membrane curvature andintracellular calcium

Journal article (peer-reviewed)abstract
- SARS-CoV-2 contains four structural proteins in its genome. These proteins aid in the assembly and budding of new virions at the ER-Golgi intermediate compartment (ERGIC). Current fundamental research efforts largely focus on one of these proteins – the spike (S) protein. Since successful antiviral therapies are likely to target multiple viral components, there is considerable interest in understanding the biophysical role of its other structural proteins, in particular structural membrane proteins. Here, we have focused our efforts on the characterization of the full-length envelope (E) protein from SARS-CoV-2, combining experimental and computational approaches. Recombinant expression of the full-length E protein from SARS-CoV-2 reveals that this membrane protein is capable of independent multimerization, possibly as a tetrameric or smaller species. Fluorescence microscopy shows that the protein localizes intracellularly, and coarse-grained MD simulations indicate it causes bending of the surrounding lipid bilayer, corroborating a potential role for the E protein in viral budding. Although we did not find robust electrophysiological evidence of ion-channel activity, cells transfected with the E protein exhibited reduced intracellular Ca2+, which may further promote viral replication. However, our atomistic MD simulations revealed that previous NMR structures are relatively unstable, and result in models incapable of ion conduction. Our study highlights the importance of using high-resolution structural data obtained from a full-length protein to gain detailed molecular insights, and eventually permitting virtual drug screening.

Book chapter (peer-reviewed)abstract
- The aim of this chapter is to explore various ways of thinking about the concept of manipulation in order to capture both current and potentially future instances of machine manipulation, manipulation on the part of everything from the Facebook advertising algorithm to super-intelligent AGI. Three views are considered: a conservative one, which slightly tweaks extant influence-based theories of manipulation; a dismissive view according to which it doesn't matter much if machines are literally manipulative, provided we can classify them as so doing to make sense of our interactions with them; and an ameliorative analysis, according to which we should change our concept of manipulation better to make sense of machine manipulation. We tentatively favor the latter.

Defining a land boundary for sustainable livestock consumption
- 2018
-
In: Global Change Biology. - : Wiley. - 1354-1013 .- 1365-2486. ; 24, s. 4185-4194
-
Research review (peer-reviewed)abstract
- The need for more sustainable production and consumption of animal source food (ASF) is central to the achievement of the sustainable development goals: within this context, wise use of land is a core challenge and concern. A key question in feeding the future world is: how much ASF should we eat? We demonstrate that livestock raised under the circular economy concept could provide a significant, nonnegligible part (9-23g/per capita) of our daily protein needs (similar to 50-60g/per capita). This livestock then would not consume human-edible biomass, such as grains, but mainly convert leftovers from arable land and grass resources into valuable food, implying that production of livestock feed is largely decoupled from arable land. The availability of these biomass streams for livestock then determines the boundaries for livestock production and consumption. Under this concept, the competition for land for feed or food would be minimized and compared to no ASF, including some ASF in the human diet could free up about one quarter of global arable land. Our results also demonstrate that restricted growth in consumption of ASF in Africa and Asia would be feasible under these boundary conditions, while reductions in the rest of the world would be necessary to meet land use sustainability criteria. Managing this expansion and contraction of future consumption of ASF is essential for achieving sustainable nutrition security.

Capacitance Effect on Microwave Power Spectra of Spin-Torque Oscillator With Thermal Noise
- 2009
-
In: IEEE transactions on magnetics. - 0018-9464 .- 1941-0069. ; 45, s. 2773-2776
-
Journal article (peer-reviewed)abstract
- A macro-spin simulation has been carried out to study the thermal stability of a spin-torque oscillator (STO) connected in parallel with a capacitance. To study the impact of realistic thermal fluctuation on an STO, a stochastic magnetic field vector is added into the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation. From the numerical solution, it is found that the addition of capacitance positively influences the thermal stability of the system, and can improve the quality factor of the microwave power spectrum even in the presence of thermal fluctuation. The results of I-V phase shift under different conditions suggest that there may exist an optimum capacitance for which the thermal stability of the system can be most enhanced.

Effects of ageing on the photosynthetic capacity of the seagrass Zostera marina Linnaeus
-
Other publication (other academic/artistic)abstract
- The effect of tissue age and light stress on seagrass productivity was examined on three scale levels by comparisons among: (i) different parts of a leaf (i.e. the base middle and top), (ii) leaves of different ages, and (iii) shoots of different development stages on the same genet, in the temperate species Zostera marina L. Rapid light curves were performed to estimate chlorophyll fluorescence and to determine the maximal photosynthetic rate (ETRmax), the photosynthetic efficiency (the alpha slope) and the maximal quantum yield (both as Fv/Fm and as the more sensible Fv/F0). The plants were also exposed to inhibiting light stress with measurements performed during the following recovery and non-photochemical quenching (NPQ). The results suggest that seagrass tissue age has an effect on the photosynthetic performance of the plant and that the level of strength varies among different parts of a single shoot and also among shoots of different development stages along the same genet. Younger and senescing tissues generally had lower photosynthetic capacity than mature tissues. It appeared that very young tissues tolerate light stress better than mature and senescing tissues, as the NPQ values of the very young tissue were higher, and they also showed a lower recovery to initial Fv/F0 values. A clear difference was also found in photosynthetic performance and recovery capacity of the youngest shoot compared to the rest of the shoots belonging to the same genet. The leaves of young shoots appeared to better tolerate light stress than leaves of old shoots. These findings provide new insight on seagrass ageing and expand the understanding of ageing effects on photosynthesis on a population level.

Examining associations, moderators and mediators between childhood maltreatment, social functioning, and social cognition in psychotic disorders : A systematic review and meta-analysis
- 2023
-
In: Psychological Medicine. - : Cambridge University Press (CUP). - 0033-2917 .- 1469-8978. ; 53:13, s. 5909-5932

Research review (peer-reviewed)abstract
- Childhood maltreatment (CM) has been related to social functioning and social cognition impairment in people with psychotic disorders (PD); however, evidence across different CM subtypes and social domains remains less clear. We conducted a systematic review and meta-analysis to quantify associations between CM, overall and its different subtypes (physical/emotional/sexual abuse, physical/emotional neglect), and domains of social functioning and social cognition in adults with PD. We also examined moderators and mediators of these associations. A PRISMA-compliant systematic search was performed on 24 November 2022 (PROSPERO CRD42020175244). Fifty-three studies (N = 13 635 individuals with PD) were included in qualitative synthesis, of which 51 studies (N = 13 260) with 125 effects sizes were pooled in meta-analyses. We found that CM was negatively associated with global social functioning and interpersonal relations, and positively associated with aggressive behaviour, but unrelated to independent living or occupational functioning. There was no meta-analytic evidence of associations between CM and social cognition. Meta-regression analyses did not identify any consistent moderation pattern. Narrative synthesis identified sex and timing of CM as potential moderators, and depressive symptoms and maladaptive personality traits as possible mediators between CM and social outcomes. Associations were of small magnitude and limited number of studies assessing CM subtypes and social cognition are available. Nevertheless, adults with PD are at risk of social functioning problems after CM exposure, an effect observed across multiple CM subtypes, social domains, diagnoses and illness stages. Maltreated adults with PD may thus benefit from trauma-related and psychosocial interventions targeting social relationships and functioning.

Sustainable development goals - Quo vadis?
- 2021
-
In: Science Reporter. - New Delhi. - 0036-8512. ; 58:3, s. 36-39
-
Journal article (pop. science, debate, etc.)abstract
- Cities are where the battle for sustainable development will be won or lost – they contribute 80% of the global GDP, and account for 70% each of global energy consumption and greenhouse gas emissions. With over two-thirds of the global population likely to live in cities by 2060, this is more than a cliché. A clutch of sustainable cities makes a sustainable province; a clutch of sustainable provinces makes a sustainable country, and it follows that several sustainable countries learning and sharing and helping other countries, will make for a sustainable world in the 21st century and further on into the future.

Assessment of Emissions and Energy Consumption for Construction Machinery in Earthwork Activities by Incorporating Real-World Measurement and Discrete-Event Simulation
- 2022
-
In: Sustainability. - : MDPI. - 2071-1050. ; 14:9, s. 5326-5326
-
Journal article (peer-reviewed)abstract
- Earthwork, an essential activity in most construction projects, consumes large quantities of fossil fuel and produces substantial air pollution with adverse environmental impacts. To achieve more sustainable construction processes, novel methodologies to evaluate and improve the performance of earthwork operations are required. This study quantifies the real-world emissions and fuel consumption of construction equipment within an earthwork project in China. Two wheel loaders and two dump trucks are examined through on-board measurements and in-lab engine tests. The duty cycles of construction equipment are categorized with respect to their power efficiency and working patterns. Moreover, the power-specific and time-based emission factors for these duty cycles are computed and compared with relevant legislative emission limits. Significant emission variations among different duty cycles were found, and the real-world emission measurements exceeded the results from the in-lab test required for emission certification. In addition, a discrete-event simulation (DES) framework was developed, validated, and integrated with the computed emission factors to analyze the environmental and energy impacts of the earthwork project. Furthermore, the equipment fleet schedule was optimized in the DES framework to reduce greenhouse gas emissions and fuel consumption by 8.1% and 6.6%, respectively.

Nanoscale Electrical and Mechanical Characteristics of Conductive Polyaniline Network in Polymer Composite Films
- 2014
-
In: ACS Applied Materials and Interfaces. - : American Chemical Society (ACS). - 1944-8244 .- 1944-8252. ; 6:21, s. 19168-19175
-
Journal article (peer-reviewed)abstract
- The presence and characteristics of a connected network of polyaniline (PANI) within a composite coating based on polyester acrylate (PEA) has been investigated. The bulk electrical conductivity of the composite was measured by impedance spectroscopy. It was found that the composite films containing PANI have an electrical conductivity level in the range of semiconductors (order of 10–3 S cm–1), which suggests the presence of a connected network of the conductive phase. The nanoscopic distribution of such a network within the cured film was characterized by PeakForce tunneling atomic force microscopy (AFM). This method simultaneously provides local information about surface topography and nanomechanical properties, together with electrical conductivity arising from conductive paths connecting the metallic substrate to the surface of the coating. The data demonstrates that a PEA-rich layer exists at the composite–air interface, which hinders the conductive phase to be fully detected at the surface layer. However, by exposing the internal structure of the composites using a microtome, a much higher population of a conductive network of PANI, with higher elastic modulus than the PEA matrix, was observed and characterized. Local current–voltage (I–V) spectroscopy was utilized to investigate the conduction mechanism within the nanocomposite films, and revealed non-Ohmic characteristics of the conductive network.

A southern perspective: Northern and indigenous influences on the establishment of a hybrid culture of participatory planning, the story of Sacaba
- 2021
-
Doctoral thesis (other academic/artistic)abstract
- Citizen participation has been discussed as an essential feature for sustainability and democracy. Normative participatory approaches, like participatory planning, developed in the North, spread across the globe as ‘placeless’ generalizations. Embedded in the context of northern cities, normative participatory planning theories resulted in serious failures in the Global South. Planning scholars engaged with the Global South argue that the usefulness of these northern approaches is conditioned by contexts that do not fit southern cities. In critique of the eurocentrism, planning scholars discuss the need for more appropriate participatory planning theory, building on southern perspectives, absent from scientific traditions. This thesis contributes to the debate for more appropriate participatory planning by investigating Bolivia’s efforts to decolonize participatory planning through an indigenous-based participatory planning legislation. Findings from a case study of Sacaba municipality show that over time different participatory ideas were adapted and combined to create a particular form of participatory planning. Conflicting rationalities between local authorities, planners and citizens regarding the purpose and scope of participation shaped both invited and invented forms of participation. I argue for the need to consider ‘hybrid cultures of participation’ tailored to the specific contexts. I further propose three lessons from Sacaba’s implementation of the indigenous-based planning legislation: 1) the need to continuously update the understanding of the local context; 2) the risk of sustaining power imbalances within institutional frameworks; and 3) the importance of promoting continuous critical reflection between authorities, planners and population.

Saproxylic biodiversity and decomposition rate decrease with small-scale isolation of tree hollows
- 2018
-
In: Biological Conservation. - : ELSEVIER SCI LTD. - 0006-3207 .- 1873-2917. ; 227, s. 226-232
-
Journal article (peer-reviewed)abstract
- Biodiversity is fundamental for ecosystem functioning, but little is known about how function responds to biodiversity loss following habitat disturbance in natural systems. Due to the global decay of veteran trees, many associated saproxylic (ie. deadwood-dependent) insects are considered threatened. Nevertheless, the role of habitat spatial configuration on saproxylic insect biodiversity and dead wood decomposition is poorly understood. We performed a six-year landscape-scale colonization experiment on saproxylic beetles inhabiting hollow oaks, using boxes filled with wood mould as standardized habitat patches. We placed boxes either on a hollow tree or on another tree 61-324 m from the hollows, thereby creating two habitat isolation levels. We quantified wood mould decay and biodiversity in the boxes, measuring species richness, total abundances and community-weighted mean of body mass (CWM) as an index of community functional composition. Isolation had a persistent negative effect on primary consumer biodiversity, but it only impaired decay at the beginning of the experiment. All effects were independent of landscape-level (500-m radius) habitat amount surrounding the boxes. Wood mould decay was mediated by CWM of primary consumers. Therefore function was driven by the body masses of the dominant primary consumer species but not by species numbers (richness) or individual numbers (abundance). Our experiment shows that small-scale habitat isolation leads to biodiversity loss and reduced function and indicates that habitats created by conservation efforts will be used by more saproxylic species if located within sites with a high density of veteran trees.

Municipal Accessibility : A Multi-linear Regression Model with a Principal Component Analysis Approach
- 2022
-
In: 2022 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM). - : IEEE. - 9781665486873 ; , s. 329-333
-
Conference paper (peer-reviewed)abstract
- Accessibility is a crucial concept in the study of social inclusion, justice, equity and security as well as the reliability of supply in societies. Research has examined factors that objectively measure accessibility, such as land-use and socioeconomics. However, such approaches often fail to include individual perceptions of accessibility. Thus, this study proposes a multi-linear regression model that focuses on both objective and subjective factors to assess municipal accessibility. In addition, principal component analysis is applied to reduce dimensionality and eliminate the problem of multi-collinearity. The paper contributes a novel model with a higher prediction rate (70.5%) than that of a traditional multi-linear regression model (58%) during an evaluation of accessibility in the Swedish context.

Interactive TV Narratives : Opportunities, Progress and Challenges
- 2008
-
In: ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP). - : Transactions on Multimedia Computing, Communications, and Applications (TOMCAAP). - 1551-6857 .- 1551-6865. ; 4:4
-
Journal article (peer-reviewed)abstract
- This paper is motivated by the question whether television should do more than simply offer interactive services alongside (and separately from) traditional linear programmes, in the context of its dominance being seriously challenged and threatened by interactive forms of screen media entertainment. It suggests: yes. Interactive narrativity, i.e. the ability to interact with (and influence) stories whilst they are being told, represents one clear development-path for interactive television. The capabilities of computing technology are ripe for exploring this new form of storytelling, from creation to commercial distribution. The paper starts with looking at the relationship between narrativity and interactivity in the current context of screen media, and identifies clear signs of interest from certain European public broadcasters in interactive TV narratives. It then presents in detail four recent experimental interactive TV productions in the genres of drama, news, and documentary, developed in collaboration with public broadcasters, which illustrate the potential and richness of this new form of storytelling, but also highlight new technological capabilities necessary for such productions. A number of essential technological requirements are then discussed in more detail in the final part. The paper suggests that the ShapeShifting Media Technology, employed in the implementation of the four productions, has made significant advances both at the technological and the creative ends in supporting the development of interactive TV narrativity, but, however, that further developments are required before being able to answer questions such as “would end users want such a form of screen media entertainment?” and “would it be effective for both end-users and producers?”

A Stratified Approach for Camera Calibration Using Spheres
- 2011
-
In: IEEE Transactions on Image Processing. - 1057-7149 .- 1941-0042. ; 20:2, s. 305-316
-
Journal article (peer-reviewed)abstract
- This paper proposes a stratified approach for camera calibration using spheres. Previous works have exploited epipolar tangents to locate frontier points on spheres for estimating the epipolar geometry. It is shown in this paper that other than the frontier points, two additional point features can be obtained by considering the bitangent envelopes of a pair of spheres. A simple method for locating the images of such point features and the sphere centers is presented. An algorithm for recovering the fundamental matrix in a plane plus parallax representation using these recovered image points and the epipolar tangents from three spheres is developed. A new formulation of the absolute dual quadric as a cone tangent to a dual sphere with the plane at infinity being its vertex is derived. This allows the recovery of the absolute dual quadric, which is used to upgrade the weak calibration to a full calibration. Experimental results on both synthetic and real data are presented, which demonstrate the feasibility and the high precision achieved by our proposed algorithm.
