description: Breaks in the surface brightness profiles in the outer regions of galactic discs are thought to have formed by various internal and external processes, and by studying the breaks we aim to better understand what processes are responsible for the evolution of the outer discs. We use a large well-defined sample to study how common the breaks are, and whether their properties depend on galaxy stellar mass or observed wavelength. We study radial surface brightness profiles of 753 galaxies, obtained from the $3.6 μm$ images of the Spitzer Survey of Stellar Structure in Galaxies (S$^4$G), and the $K_s$-band data from the Near InfraRed S0-Sa galaxy Survey (NIRS0S), covering a wide range of galaxy morphologies and stellar masses. Optical SDSS or Liverpool telescope data was used for 480 of these galaxies. We find that in low-mass galaxies the single exponential discs (Type I) are most common, and that their fraction decreases with increasing galaxy stellar mass. The fraction of down-bending (Type II) discs increases with stellar mass, possibly due to more common occurrence of bar resonance structures. The up-bending (Type III) discs are also more common in massive galaxies. The observed wavelength affects the scalelength of the disc of every profile type. Especially the scalelength of the inner disc of Type II profiles increases from infrared to u-band on average by a factor of $\sim 2.2$. Consistent with the previous studies, we find that Type II outer disc scalelengths ($h_o$) in late-type and low-mass galaxies are shorter in bluer wavelengths, possibly due to stellar radial migration populating the outer discs with old stars. In Type III discs $h_o$ are larger in the u-band, hinting to the presence of young stellar population in the outer disc. While the observed wavelength affects the disc parameters, it does not significantly affect the profile type in our sample. (Abridged)

description: This short research note was contributed to the paper (The Coming Decade of Digital brain.... Amunds et al) : The collision of increasingly powerful and AI driven digital technologies and vast amounts of
 brain data, which are growing exponentially at increasing levels of granularity is creating
 unprecedented opportunities and challenges for neuroscience.
 \
 The rate of acquisition of new knowledge from research data is higher than the ability of the
 research community to process and act upon new findings. The adoption of informatics is necessary but in turn, it brings increasing layers of complexity
 and codification.

 To ensure trustworthiness and reliability, the convergence of digital technologies and brain data must be supported by shared knowledge
 representation models, so that the data structures and their encodings become universally accessible to researchers with diverse backgrounds and specializations.
 To some extent, these shared models are being developed and harmonized, although they are limited in scope.
 ;
 The evolution of neuromorphic computing comes with enormous complexities and risks thus increasing the need for accurate transparent and reliable knowledge models to ensure the accountability of computational models and infrastructures
 relying on powerful new technologies and architectures, yet devising such models is non-trivial, especially taking into account the dynamics of
 emergent knowledge in the context of shifting scientific paradigms.

 System level approaches that enable whole brain science need to be supported by system level knowledge representation to serve as the basis for
 adequate computational environments, while reducing the computational load. Systemic approaches must not only include function and structure models, but also requires
 the alignment of behavior, a characterization of behavioral aspects has been provided as a contribution to the ebrains/HBP project.

 Experiments must evaluate the different combinations of interactions between structure
 function and behaviors and scale free computation must be achieved to support the dynamic evolution of capabilities
 New Understanding of higher order cognitive functions such as meta cognition must drive the research
 agenda. Neurosymboilc integration using model cards can be leveraged to facilitate this convergence

description: Many tourists have cancelled their trips to Kenya in response to global travel restrictions due to COVID-19. Plummeting demand has triggered a crisis that is being felt throughout the entire tourism ecosystem. Most tourist activities and businesses have been closed, and others are operating at a lower level, resulting in massive revenue and job losses. Whilst tourism has proven to be resilient to shocks, including terrorism, violence, natural disasters, economic recession, and pandemics, none of the disruptive events has ever had such a phenomenal impact on the world’s economy, especially the tourism economy as COVID-19 (UNWTO, 2020). The impact of COVID-19 will most likely last longer, rendering the future bleak, and the road to recovery is uncertain, but much will depend on appropriate policy stimulus to mitigate the effects of COVID-19 and kickstart a rebirth of Kenya's tourism industry.

description: The present qualitative study examines the healthcare provision for older adults in two villages in Northern Greece. Through semi-structured interviews, satisfaction with the healthcare system, relationships with physicians, the presence of a regular doctor, preventive health behaviors, and polypharmacy were addressed. Data were collected from a total of 24 men and women over 61 years old, originating from the two villages in the same region. Data were coded and thematically analyzed. It emerged that most participants are satisfied with the healthcare system, although they often pay for several services. Furthermore, most older adults have a regular doctor they visit, usually a pathologist or cardiologist, and the relationship with their physicians and communication within it, appear to be particularly important for the participants. Additionally, the majority of participants had a stable private doctor and did not frequently use hospital services. The public healthcare service used by all participants seems to be the receipt of free or subsidized medication. Finally, the absence of community-based and organized preventive interventions for this group is significant.

description: We propose a new peridynamic formulation with shear deformation for linear elastic solid. The key idea lies in subtracting the rigid body rotation part from the total deformation. Based on the strain energy equivalence between classic local model and non-local model, the bond force vector is derived. A new damage rule of maximal deviatoric bond strain for elastic brittle fracture is proposed in order to account for both the tensile damage and shear damage. 2D and 3D numerical examples are tested to verify the accuracy of the current peridynamics. The new damage rule is applied to simulate the propagation of Mode I, II and III cracks.

Postharvest Loss

description: Historically, horticultural research has focused on increasing productivity. However, given the inelasticity of scarce resources, there is a consensus that the focus should shift to PHL reduction. The high postharvest losses occur due to poor postharvest handling, lack of storage technologies, lack of processing facilities, and poor market access. Developing cold chains is critical in PHL. reduction in horticulture. However, conventional cold storage facilities required for proper cold chains are expensive and not applicable in most rural areas due to lack of electricity. Most households (>80%) in rural Kenya have no access to electricity making it untenable and costly to invest in cold storage facilities (GoK, 2008; Shitanda et al., 2011). Consequently, the lack of cold storage facilities to aggregate the perishable produce and negotiate for better prices predisposes the smallholders to exploitation by middlemen. Globally, applicable off-grid cold storage and processing technologies exist. However, their adoption in Kenya is limited due to a lack of awareness and demonstrated benefits. It is against this background, that the University of Nairobi’s postharvest project, with support from the Rockefeller Foundation’s YieldWise Initiative, sought to upgrade two fruit aggregation centres. Low-cost technologies including zero-energy brick coolers, evaporative charcoal coolers, and tunnel solar dryers were provided to create awareness and demonstrate their practical application. However, little is known about their economic impact in Kenya, hence this study.

description: It was previously reported, that temperature may significantly influence neural dynamics on different levels of brain modelling. Due to this fact, while creating the model in computational neuroscience we would like to make it scalable for wide-range of various brain temperatures. However currently, because of a lack of experimental data and an absence of analytical model describing temperature influence on synapses, it is not possible to include temperature effects on multi-neuron modelling level. In this paper, we propose first step to deal with this problem: new analytical model of AMPA-type synaptic conductance, which is able to include temperature effects in low-frequency stimulations. It was constructed on basis of Markov model description of AMPA receptor kinetics and few simplifications motivated both experimentally and from Monte Carlo simulation of synaptic transmission. The model may be used for efficient and accurate implementation of temperature effects on AMPA receptor conductance in large scale neural network simulations. This in fact, opens wide-range of new possibilities for researching an influence of temperature on brain functioning.

description: In Kenya, several social safety net programmes have been initiated to support lives and livelihoods and to enhance resilience to shocks. The existing social safety net programmes in the Country include the Hunger Safety Net Programme, Orphans and Vulnerable Children Cash Transfer, Older Persons Cash Transfer Programme, People Living with Severe Disabilities Cash Transfer Programme, and the Urban Food Subsidy Cash Transfer Programme (NGEC, 2014). These are per Article 21 of the Constitution of Kenya, which puts forward that it is the responsibility of the State to ensure that the economic and social rights of citizens are met (Constitution of Kenya, 2010). Government ownership of social safety net initiatives has shown some hope for the implementation of the programmes. However, the sustainability of the programmes is a major worry due to their dependence on donors' funding and technical support (Barrientos and Hume, 2009). Despite the approval of the National Social Protection Policy in 2011, Kenya has continued to record a high incidence of poverty coupled with food insecurity and malnutrition, made worse by disasters and stresses (Ministry of State for Planning and National Development, 2012). The purpose of this study, therefore, focused on the current social safety nets in Turkana County, primarily on the use of cash transfer programmes and its role in community resilience and food security. Turkana County is among the semi-arid lands of Kenya prone to drought and suffers from historical marginalization, struggling with weak infrastructure as well as high rates of illiteracy (OPM 2011). The County is among the four ASAL counties where the Hunger Safety Net Programme (HSNP) was piloted as a viable solution to the eradication of poverty, hunger and malnutrition in the longer term.

description: A sunspot acts as a waveguide in response to the dynamics of the solar interior; the trapped waves and oscillations could reveal its thermal and magnetic structures. We study the oscillations in a sunspot intruded by a light bridge, the details of the oscillations could reveal the fine structure of the magnetic topology. We use the Solar Dynamics Observatory/Atmospheric Imaging Assembly data to analyse the oscillations in the emission intensity of light bridge plasma at different temperatures and investigate their spatial distributions. The extreme ultraviolet emission intensity exhibits two persistent oscillations at five-minute and sub-minute ranges. The spatial distribution of the five-minute oscillation follows the spine of the bridge; whereas the sub-minute oscillations overlap with two flanks of the bridge. Moreover, the sub-minute oscillations are highly correlated in spatial domain, however, the oscillations at the eastern and western flanks are asymmetric with regard to the lag time. In the meanwhile, jet-like activities are only found at the eastern flank. Asymmetries in forms of oscillatory pattern and jet-like activities \textbf{are} found between two flanks of a granular light bridge. Based on our study and recent findings, we propose a new model of twisted magnetic field for a light bridge and its dynamic interactions with the magnetic field of a sunspot.

description: It has been shown previously for electrodeposited Co/Cu multilayers that the single-bath electrodeposition process can be optimized from an electrochemical point of view in order to avoid unwanted Co dissolution and incorporation of Co in the non-magnetic layer during the Cu deposition pulse. In the present work, electrodeposition of Ni-Co/Cu multilayers has been studied to clarify if the same optimization method is appropriate when two magnetic elements are present and if this potential results in the largest giant magnetoresistance (GMR) for the particular alloy system studied. For this purpose, several Ni-Co/Cu multilayers were prepared by varying the deposition potential of the Cu layer. The composition analysis of the deposits showed that the Ni:Co ratio exhibits a minimum as a function of the Cu deposition potential, which can be explained by considering both the dissolution of Co and the mass transport of the reactants. Both the saturation GMR value and the intensity of the satellite peaks in the X-ray diffractograms were highly correlated with the resulting surface roughness of the deposits which was strongly varying with the Cu deposition potential. Higher GMR values, lower saturation fields and more perfect multilayer structure were observed for sufficiently positive Cu deposition potentials only which enabled a partial Co dissolution resulting in a reduced surface roughness. The results draw attention to the complexity of the optimization procedure of the deposition of multilayers with several alloying components.

Atomic displacements of Ru and P, reflecting the field-induced charge order of the $p$ electrons, have been deduced by analyzing the intensities of the forbidden Bragg peaks, assuming a cubic space group $Pm\bar{3}$. Also, by utilizing high-resolution x-ray diffraction experiment, we observed a splitting of fundamental Bragg peaks, clarifying that the unit cell in the magnetic ordered phase is rhombohedral elongated along the $[1\, 1\, 1]$ axis. Responses of the rhombohedral domains to the magnetic field, which reflects the direction of the magnetic moment, is studied in detail.

description: Gigahertz-to-terahertz spectroscopy of macromolecules in aqueous environments provides an important approach for identifying their global and transient molecular structures, as well as directly assessing hydrogen-bonding. We report dielectric properties of zwitterionic dodecylphosphocholine (DPC) micelles in aqueous solutions over a wide frequency range, from 50 MHz to 1.12 THz. The dielectric relaxation spectra reveal different polarization mechanisms at the molecular level, reflecting the complexity of DPC micelle-water interactions. We have made a deconvolution of the spectra into different components and combined them with the effective-medium approximation to separate delicate processes of micelles in water. Our measurements demonstrate reorientational motion of the DPC surfactant head groups within the micelles, and two levels of hydration water shells, including tightly- and loosely-bound hydration water layers. From the dielectric strength of bulk water in DPC solutions, we found that the number of waters in hydration shells is approximately constant at 950 +/- 45 water molecules per micelle in DPC concentrations up to 400 mM, and it decreases after that. At terahertz frequencies, employing the effective-medium approximation, we estimate that each DPC micelle is surrounded by a tightly-bound layer of 310 +/- 45 water molecules that behave as if they are an integral part of the micelle. Combined with molecular dynamics simulations, we determine that tightly-bound waters are directly hydrogen-bonded to oxygens of DPC, while loosely-bound waters reside within 4 A of micellar atoms. The dielectric response of DPC micelles at terahertz frequencies yields, for the first time, experimental information regarding the largest-scale, lowest frequency collective motions in micelles.

Water Burden

description: Following confirmation of the first case of the novel Coronavirus Disease (COVID-19) in Kenya in March 2020, the Government issued an advisory in ensuring high standards of hygiene through regular handwashing using soap and water. A national protocol on COVID- 19 was launched, which among others, underscored handwashing and high levels of hygiene maintenance. These required an increased household water demand that caused elevated household water bills, leaving poor households vulnerable to water insecurity. The pandemic has severely modified the patterns and behaviour of the economy of water (Vammen and Guillen, 2020). Water service providers (WSPs) have also been adversely affected. The Lodwar Water and Sanitation Company (LOWASCO), for instance, finds it hard to effectively supply clean water due to decreased revenues from non-payment (LOWASCO official, pers. comm.). With the government's directive that WSPs should not disconnect water supply for 3 months (March-May 2020) including households in default, WSPs faced challenges in meeting some of their operational costs such as power bills and staff wages (Senkwe and Gakubia, 2020). The directive is far from adequate, largely temporary, and unsustainable (Senkwe and Gakubia, 2020).

description: The role of compressible fluctuations in the energy cascade of fast solar wind turbulence is studied using a reduced form of an exact law derived recently (Banerjee and Galtier, PRE, 2013) for compressible isothermal magnetohydrodynamics and in-situ observations from the THEMIS B/ARTEMIS P1 spacecraft. A statistical survey of the data revealed a turbulent energy cascade over two decades of scales, which is broader than the previous estimates made from an exact incompressible law. A term-by-term analysis of the compressible model reveals new insight into the role played by the compressible fluctuations in the energy cascade. The compressible fluctuations are shown to amplify (2 to 4 times) the turbulent cascade rate with respect to the incompressible model in 10 % of the analyzed samples. This new estimated cascade rate is shown to provide the adequate energy dissipation required.

description: Inducing magnetic moment in otherwise nonmagnetic two-dimensional semiconducting materials is the key first step to design spintronic materials. Here, we study the absorption of transition-metals on pristine and defected single-layer phosphorene, within density functional theory. We predict that increased transition-metal diffusivity on pristine phosphorene would hinder any possibility of controlled magnetism, and thus any application. In contrast, the point-defects will anchor metals, and exponentially reduce the diffusivity. Similar to other two-dimensional materials, metals bind strongly on both pristine and defected phosphorene, and we provide a microscopic description of bonding, which explain the qualitative trend with increasing number of valence electrons. We further argue that the divacancy complex is imperative in any practical purpose due to their increased thermodynamic stability over monovacancy. For most cases, the defect-transition metal complexes retain the intrinsic semiconduction properties, and also induce a local magnetic moment with large exchange-splitting and spin-flip energies, which are necessary for spintronic applications. Specifically, the V/Mn/Fe absorbed at the divacancy have tremendous promise in this regard. Further, we provide a simple microscopic model to describe the local moment formation in these transition metal and defect complexes.

Can Larger Ships Sail Through Paris?

Publisher: name: Zenodo

description: Traversing the river Seine in Paris is challenging for inland ships due to the density and diversity of local traffic (cargo and passengers) and the variety of manoeuvres that are encountered. On top of that, there is a high number of historically important bridges, where traffic has to pass underneath narrow arches, while taking into account delicate current conditions on a bending trajectory.
 Some decades ago, regulations concerning the maximum ship dimensions depending on the water level of the river were put in place to ensure the safety of navigation. However, with a growing interest in inland waterway transportation (economic, environmental and logistical advantages compared to rail or road transport) and with new types of ships plying the waterway, the question arose whether the regulations are still up to date. To this end, the waterway authority, Voies navigables de France (VNF), commissioned a study to assess the relevance of these regulations when present and future vessels of varying types and dimensions cross Paris. The study was carried out by the Maritime Technology Division at Ghent University in cooperation with International Marine and Dredging Consultants (IMDC), Flanders Hydraulics Research and Siradel.
 This poster presents how ship manoeuvring simulators are used to assess the maximum dimensions of ships crossing the Seine in Paris.
 Real time simulations were carried out by skippers familiar with the crossing of Paris and the analysis is based on their feedback as well as a selection of safety criteria.
 The simulations have shown that the main bottlenecks are related to the succession of passages under narrow bridges with non-aligned openings. Maximum water levels for which safe passage is possible, were determined for each ship type and compared with the actual regulations. Finally, recommendations have been formulated, which were then discussed with VNF and the stakeholders.

description: The Solanum wild relatives are valuable for developing pest and disease-resistant lines in the breeding program of S. melongena (brinjal). However, breeding new varieties that are superior to the existing ones in S. melongena faces several challenges. To overcome geographical and seasonal barriers, a breeding strategy involving pollen cryopreservation may be helpful. Fifteen different Solanum species/accessions of wild relatives and two accessions from cultivated species were studied for in vitro germination and fertility. Among these S. indicum accessions exhibited the highest fresh pollen germination of 92.7±0.7 (JRPH/15–154) and 88.2±3.2% after 1 year and 4 months of cryostorage. In vivo fertility was estimated by quantifying fruit set after pollination with both fresh and cryopreserved pollen. The cryopreserved pollen was able to set fruit (91.5±0.5 in JRPH/15–154) compared to fresh pollen (100%). Scanning Electron Microscopic studies (SEM) were conducted on both fresh and cryopreserved pollen, and various morphological parameters such as pollen length, breadth, and perimeter were recorded for all the accessions and species. These studies explore the possibility of establishing a pollen cryobank for Solanum wild species.

description: Nonlinear similarity measures defined in kernel space, such as correntropy, can extract higher-order statistics of data and offer potentially significant performance improvement over their linear counterparts especially in non-Gaussian signal processing and machine learning. In this work, we propose a new similarity measure in kernel space, called the kernel risk-sensitive loss (KRSL), and provide some important properties. We apply the KRSL to adaptive filtering and investigate the robustness, and then develop the MKRSL algorithm and analyze the mean square convergence performance. Compared with correntropy, the KRSL can offer a more efficient performance surface, thereby enabling a gradient based method to achieve faster convergence speed and higher accuracy while still maintaining the robustness to outliers. Theoretical analysis results and superior performance of the new algorithm are confirmed by simulation.

description: This thesis focuses on input latency in machine control over wireless communication networks. Latency is one of the essential factors defining the performance of machine control systems. How the latency affects the performance of machine control systems needs to figure out. And how the key factors that affect latency (baud rate, payload packet size and operating distance) need to analysis. In this thesis, a new system for machine control over wireless communication is proposed. The system’s latency performance is assessed. The developed system is tested in latency-sensitive applications. This thesis adopts an innovative analytical and methodological approach to the study of latency in machine control over wireless communication channels. For this thesis, 4G LTE and XBee radio were both used in experiments as the radio channels in a modelled machine control over a wireless communication system. After data was collected from the experiments, distributions for 4G LTE and XBee radio channel latency were created, and the best fit was expressed as a Rician distribution. The latency sensitive applications in this research were used to determine the XBee and 4G LTE channels latency boundaries while the simulation was used to link latency to the performance of the applications. It was discovered that, in an object of interest (OOI) tracking system, latency in the wireless communication link can be considered a low priority when attempting to improve the performance of an OOI tracking system. In a drone navigation system, it is essential that latency in the communication channel is below 33 ms. In the forest scenario, the maximum safe drone velocity was found to be 4.4 m/s when using a 4G LTE communication channel.

description: Living in a city or a metropolitan area is a great promotion for human well-being, given its convenient mode of life and efficient way of working. This is so for Kenyan cities, Nairobi included. However, concerns are emerging from residents and scientists that the unprecedented development of cities has caused a range of environmental problems and exerts huge pressure on natural ecosystems that we rely on (UNEP, 2016; Asian Coalition for Housing Rights 2004; Muthama, 2019a). Several parts of Kenyan cities continue to experience overwhelming solid waste challenges and air pollution impacts among other environmental concerns. The 2017 Kenya Economic Survey estimated that 19.9 million Kenyans, representing 38.3% of the population, suffered from respiratory ailments that are exacerbated by poor air quality. The 2019 Kenya Economic Survey estimated that 21.8 million Kenyan, representing 39.3% of Kenyans, suffered from the respiratory ailment, indicating a 1% increase of the ailments at the national level. This is a pointer that the air pollution problem may be increasing.

description: Motivated by the structure of certain modules over the loop Virasoro Lie conformal algebra and the Lie structures of Schrodinger-Virasoro algebras, we construct a class of infinite rank Lie conformal algebras CSV (a, b), where a, b are complex numbers. The conformal derivations of CSV (a, b) are uniformly determined. The rank one conformal modules and Z-graded free intermediate series modules over CSV (a, b) are classified. Corresponding results of the conformal subalgebra CHV (a, b) of CSV (a, b) are also presented.

description: In this snapshot of modern mathematics we describe some of the most prevalent waves and patterns that can arise in mathematical models and which are used to describe a number of biological, chemical, physical, and social processes. We begin by focussing on two types of patterns that do not change in time: space-filling patterns and localized patterns. We then discuss two types of waves that evolve predictably as time goes on: spreading waves and rotating waves. All our examples are motivated with real-world applications and we highlight some of the main lines of research that mathematicians pursue to better understand them.

description: The neonatal phase of human life is particularly important and raises ethical and legal issues, which are intractable and preoccupy bioethical thought as well as legal scholars. This approach has been the driving force behind the preparation of this thesis, which calls for listing, analyzing, and classifying the ethical concerns raised, as well as presenting the means, both ethical and legal, which must be defended and protect this vulnerable but important phase of human growth and development, called the human neonatal phase. In the general part of the research, we will include the analysis of basic terms (ethical and legal status) and listing of the main problematics (death in the neonatal phase and euthanasia). In the continuation and the special part, we will try to delve into problematic, sub-categories and their components, which include the types of neonatal euthanasia, transplants and also special categories of study (such as guidelines).

description: Background: Globally, suicide is the fourth highest cause of adolescent mortality (Suicide: https://www.who.int/ news-room/fact-sheets/detail/suicide). The effects of post-primary school-based suicide prevention (PSSP) on adolescent suicidal thoughts and behaviours (STBs) have not been comprehensively synthesised. We aim to estimate the population effect for PSSP interventions on adolescent STBs and explore how intervention effects vary based on intervention and contextual moderators. Methods: Searches of PsycINFO, Medline, Education Source, ERIC, Web of Science, and the Cochrane Central Register of Controlled Trials identified cluster randomised trials examining the effectiveness of PSSP on adolescent STBs. The Cochrane Risk of Bias tool assessed bias. Crude and adjusted back-transformed odds ratios (ORs) were calculated. Multilevel random-effects models accounted for dependencies of effects. Univariate meta-regression explored variability of intervention and contextual moderators on pooled effects. Results: There were 19 and 12 effects for suicidal ideation (SI) and suicide attempts (SA). Compared with controls, interventions were associated with 13% (OR = 0.87, 95%CI [0.78, 0.96]) and 34% (OR = 0.66, 95%CI [0.47, 0.91]) lower crude odds reductions for SI and SA, respectively. Effects were similar for adjusted SI (OR = 0.85, 95%CI [0.75, 0.95]) and SA (OR = 0.72, 95%CI [0.59, 0.87]) models. Within-study (0.20–9.10%) and between-study (0–51.20%) heterogeneity ranged for crude and adjusted SA models and SI heterogeneity was 0%. Moderator analyses did not vary SA effects (ps > .05). Conclusions: This meta-analysis contributes to the PSSP evidence-base by demonstrating that PSSP targeting STBs as both primary intervention outcomes and with other health and well-being outcomes reduced SI and SA among 33,155 adolescents attending 329 schools, compared to controls. The number needed to treat estimates suggests the potential of reducing the incidence of SA and SI in one adolescent by implementing PSSP in 1–2 classrooms, supporting PSSP as a clinically relevant suicide prevention strategy. Although moderator analyses were nonsignificant and contained a small number of trials, larger SA effect sizes support particular effectiveness for interventions of a duration of ≤1 week, involving multiple stakeholders and with a 12-month follow-up
