description: The multidimensional energy surface of a cholesteric liquid crystal in a planar cell is investigated as a function of spherical coordinates determining the director orientation. Minima on the energy surface correspond to the stable states with particular director distribution. External electric and magnetic fields deform the energy surface and positions of minima. It can lead to the transitions between states, known as the Fréedericksz effect. Transitions can be continuous or discontinuous depending on parameters of the liquid crystal which determine an energy surface. In a case of discontinuous transition when a barrier between stable states is comparable with the thermal energy, the activation transitions may occur and it leads to the modification of characteristics of the Fréedericksz effect with temperature without explicit temperature dependencies of liquid crystal parameters. Minimum energy path between stable states on the energy surface for the Fréedericksz transition is found using geodesic nudged elastic band method. Knowledge of this path, which has maximal statistical weight among all other paths, gives the information about a barrier between stable states and configuration of director orientation during the transition. It also allows one to estimate the stability of states with respect to the thermal fluctuations and their lifetime when the system is close to the Fréedericksz transition.

description: More than five million under-five children lose their lives each year, globally. The loss remains concentrated in settlements of the global south. Lack of access to safe drinking water and enduring polluted indoor environment are the primary causes of the colossal loss. Providing clean water to these deprived communities necessitates suitable water treatment. But, treating water is energy-intensive, and inadequate access to water is often found in areas with poor energy access. Likewise, adopting electric cooking to reduce indoor air pollution requires a stable supply. Nevertheless, energy access has advanced in the recent past. Off-grid utilities are increasingly centering on solar photovoltaic generation to extend access to consumption-limited access-tiers. These utilities may not be able to power a reverse osmosis based water treatment facility or an induction cookstove. However, leveraging evolving technology, efficient use of solar PV could power water treatment and clean cooking. Recent advances in demand-side management extend necessary capacity for cooperative consumption. Prosumer collaboration may lead to declining levelised cost of energy, expanding energy access, and reduced child mortality. The results highlight the importance of prosumer collaboration for efficient resource utilization and favorable cost of energy access.

description: Weather data are evaluated in view of their influence on high-quality PV energy yield predictions based on machine learning algorithms (MLAs). Optimisation experiments evidence that the prediction quality can be increased to over 30% by incorporating specific weather parameters in the ML-training. The results will feed into a planning tool for optimising the own consumption (including in wintertime) of PV plant owners. The outcome of this study also illustrates evolving best practice in using meteorological data to produce PV energy yield predictions with specific MLAs.

description: Background: Posttraumatic stress disorder (PTSD) involves a complex interaction of biological, psychological, and social factors. Numerous studies have demonstrated genetic variation associated with the development of PTSD, primarily in adults. However, the contribution of low frequency and rare genetic variants to PTSD is unknown to date. Moreover, there is limited work on genetic risk for PTSD in child and adolescent populations. Objective: This preliminary study aimed to identify the low frequency and rare genetic variation that contributes to PTSD using an exome array. Method: This post-disaster, adolescent sample (n = 707, 51% females, Mage = 14.54) was assessed for PTSD diagnosis and symptom count following tornado exposure. Results: Gene-based models, covarying for ancestry principal components, age, sex, tornado severity, and previous trauma identified variants in four genes associated with diagnosis and 276 genes associated with symptom count (at padj < .001). Functional class analyses suggested an association with variants in the nonsense class (nonsynonymous variant that results in truncation of, and usually non-functional, protein) with both outcomes. An exploratory gene network pathway analysis showed a great number of significant genes involved in brain and immune function, illustrating the usefulness of downstream examination of gene-based findings that may point to relevant biological processes. Conclusions: While further investigation in larger samples is warranted, findings align with extant PTSD literature that has identified variants associated with biological conditions such as immune function. • This study aimed to identify low frequency and rare genetic variation that contributes to PTSD using an exome array in a disaster-exposed adolescent sample. • Gene-based models, identified 4 genes associated with PTSD diagnosis and 276 genes associated with PTSD symptom count. • Functional class analyses suggested an association with the nonsense class with both outcomes. • Networks related to immune function appeared to be particularly relevant.
On the Existence of Additional (Hydrino) states in the Dirac equation

description: In case of spinless particles there appear additional (singular) solutions in the framework of relativistic Klein-Gordon equation for Coulomb potential. These solutions obey to all requirements of quantum mechanical general principles. Observation of such states (hydrino, small hydrogen) should be important for manifestation of various physical phenomena. In this article the same problem is considered for spin-1/2 particle (electron) in the Dirac equation. It is shown that such kind of solutions really occurs, but the rate of singularity is more higher than in spinless case. By this reason we have no time- independence of total probability (norm). Moreover the orthogonality property is also failed, while the total probability is finite in the certain area of the model-parameters. Therefore, we are inclined to conclude that this additional solution in the Dirac equation must be ignored and restrict ourselves only by normal (standard) solutions.

description: We use quasiparticle anisotropic hydrodynamics to study an azimuthally-symmetric boost-invariant quark-gluon plasma including the effects of both shear and bulk viscosities. In quasiparticle anisotropic hydrodynamics, a single finite-temperature quasiparticle mass is introduced and fit to the lattice data in order to implement a realistic equation of state. We compare results obtained using the quasiparticle method with the standard method of imposing the equation of state in anisotropic hydrodynamics and viscous hydrodynamics. Using these three methods, we extract the primordial particle spectra, total number of charged particles, and average transverse momentum for various values of the shear viscosity to entropy density ratio eta/s. We find that the three methods agree well for small shear viscosity to entropy density ratio, eta/s, but differ at large eta/s. We find, in particular, that when using standard viscous hydrodynamics, the bulk-viscous correction can drive the primordial particle spectra negative at large p_T which is clearly unphysical. Such a behavior is not seen in either anisotropic hydrodynamics approach, irrespective of the value of eta/s.

description: This paper assesses the conditions in which photovoltaic (PV) generators and energy storage systems could be added to existing wind power plants to create a hybrid co-located Wind-PV or Wind-PV-storage grid connected power plant. The approach consists of a sensitivity analysis of the impacts of adding PV generation to wind power plants considering the possibility of complementary primary resources (both on daily and seasonal bases), the project total cost, the use of infrastructure and the avoided costs due to hybridization. Moreover, a study case of a preliminary hybridization potential assessment in two different regions of Brazil is carried out. Preliminary results show that, although there is great availability of primary resource for both wind and solar energy in the Northeastern coast of Brazil, there is not much negative correlation between the primary resources, which diminishes the attractiveness for hybridization. Some complementarity is found, however, in some inland areas, particularly in the state of Bahia, where the least amount of wind normally occurs in the middle of the day, when the sun is at its peak.

description: We investigate the triggering of star formation in clouds that form in Galactic scale flows as the ISM passes through spiral shocks. We use the Lagrangian nature of SPH simulations to trace how the star forming gas is gathered into self-gravitating cores that collapse to form stars. Large scale flows that arise due to Galactic dynamics create shocks of order 30 km/s that compress the gas and form dense clouds $(n> $several $\times 10^2$ cm$^{-3}$) in which self-gravity becomes relevant. These large-scale flows are necessary for creating the dense physical conditions for gravitational collapse and star formation. Local gravitational collapse requires densities in excess of $n>10^3$ cm$^{-3}$ which occur on size scales of $\approx 1$ pc for low-mass star forming regions ($M<100 M_{\odot}$), and up to sizes approaching 10 pc for higher-mass regions ($M>10^3 M_{\odot}$). Star formation in the 250 pc region lasts throughout the 5 Myr timescale of the simulation with a star formation rate of $\approx 10^{-1} M_{\odot}$ yr$^{-1}$ kpc$^{-2}$. In the absence of feedback, the efficiency of the star formation per free-fall time varies from our assumed 100 % at our sink accretion radius to values of $< 10^{-3}$ at low densities.

description: Background: Analysis of dynamic (temporal) networks allows an identification of important targets of treatment. Objective: This study examined the dynamic network of symptoms in patients diagnosed with post-traumatic stress disorder (PTSD) during exposure therapy. Method: Patients (n = 65) were randomized to either standard prolonged exposure, which includes imaginal exposure to the traumatic memory, or modified prolonged exposure, where imagery re-scripting of the memory replaced imaginal exposure, in a 10-week residential program. They completed a measure of DSM-IV PTSD symptoms weekly. The multilevel vector autoregressive (mlVAR) model was used to analyse the data, producing a temporal (dynamic), contemporaneous, and between-person network. Results: Physiological reactivity to reminders in a given week was positively related to distress reactivity and to flashbacks the subsequent week. Hypervigilance one week was positively related to startle response and external avoidance the subsequent week. In addition, sleep problems were positively predicted by previous week internal avoidance and negatively predicted by previous week flashbacks. Hypervigilance and physiological reactivation had the highest out-strength, indicating that they were the most predictive of other symptoms. Conclusions: The present within-person results make a preliminaryrect basis for the recommendation to monitor and facilitate change in physiological reactivation and hypervigilance in the treatment of PTSD. Future studies should examine the replicability of our temporal PTSD network and also include causal variables beyond symptoms. • Dynamic networks of PTSD symptoms may reveal useful targets of treatment.• Hypervigilance and physiological reactivity to reminders were most predictive.• Physiological reactivity predicted subsequent distress reactivity and flashbacks.• Hypervigilance predicted subsequent startle response and external avoidance.

description: In response to the marked increase in research activity and publications about Vehicle Integrated PhotoVoltaics (VIPV), this article is an attempt to identify the main constraints relative to the manufacturing of curved PV modules for automotive application and the interests of composite modules in this context. Two processes have been selected as better adapted to the automotive industrialization and in-mold integration of PV cells: Resin Transfer Molding (RTM) and thermocompression. A finite element analysis (FEA) to evaluate the mechanical strength of the resulting module is proposed. The aim of this numerical approach is to optimize the mechanical performance of the structure. First results were validated by a comparison of simulation outputs with 3-point bending test measurements.

description: We understand emergent quantum mechanics in the sense that quantum mechanics describes processes of physical emergence relating an assumed sub-quantum physics to macroscopic boundary conditions. The latter can be shown to entail top-down causation, in addition to usual bottom-up scenarios. With this example it is demonstrated that definitions of "realism" in the literature are simply too restrictive. A prevailing manner to define realism in quantum mechanics is in terms of pre-determination independent of the measurement. With our counter-example, which actually is ubiquitous in emergent, or self-organizing, systems, we argue for realism without pre-determination. We refer to earlier results of our group showing how the guiding equation of the de Broglie-Bohm interpretation can be derived from a theory with classical ingredients only. Essentially, this corresponds to a "quantum mechanics without wave functions" in ordinary 3-space, albeit with nonlocal correlations. This, then, leads to the central question of how to deal with the nonlocality problem in a relativistic setting. We here show that a basic argument discussing the allegedly paradox time ordering of events in EPR-type two-particle experiments falls short of taking into account the contextuality of the experimental setup. Consequently, we then discuss under which circumstances (i.e. physical premises) superluminal information transfer (but not signaling) may be compatible with a Lorentz-invariant theory. Finally, we argue that the impossibility of superluminal signaling - despite the presence of superluminal information transfer - is not the result of some sort of conspiracy (a la "Nature likes to hide"), but the consequence of the impossibility to exactly reproduce in repeated experimental runs a state's preparation, or of the no-cloning theorem, respectively.

description: Background: Trauma adjustment varies in children and adolescents. Studies on objective risk factors of posttraumatic stress symptoms (PTSS) yielded inconsistent results. Dysfunctional posttraumatic cognitions (PTCs) might play a mediating role between risk factors and posttraumatic symptomatology. Objective: To investigate the interplay of the characteristics of the trauma (e.g. trauma type), the characteristics of the individual (e.g. age, sex), and the characteristics of the social environment (e.g. parental distress, marital status) on PTSS and depression, taking the child’s dysfunctional PTCs into account as a possible mediator. Method: Structural equation modelling was used to better understand trauma adjustment in two heterogeneous samples of children and adolescents: a sample of 114 participants aged 7–16 after accidental trauma and a sample of 113 participants aged 6–17 after interpersonal trauma. Results: In the accidental trauma sample, dysfunctional PTCs mediated the positive associations of younger age and lower parental educational level on child PTSS, but not on depression. In the interpersonal trauma sample, being female positively predicted child depression. Furthermore, parental dysfunctional PTCs positively predicted both child PTSS and depression. No mediation effect of child dysfunctional PTCs was found in the interpersonal trauma sample. Child dysfunctional PTCs moderately to strongly predicted child PTSS and depression in both trauma samples. Conclusions: The impact of the characteristics of the individual and the characteristics of the social environment on child PTSS and depression might depend on the type of trauma experienced. Dysfunctional PTCs mediated between the characteristics of the individual and the characteristics of the social environment and the severity of PTSS in the aftermath of accidental trauma, but not of interpersonal trauma. • Dysfunctional posttraumatic cognitions (PTCs) were associated with posttraumatic stress symptoms (PTSS) and depression.• In accidentally injured children, dysfunctional PTCs mediated between the characteristics of the individual and the characteristics of the social environment and the severity of PTSS.

description: The PHOTOPUR project aims to develop a photocatalytic process as a type of AOPs (Advanced Oxidation Processes) for the elimination of plant protection products (PPP) of the cleaning water used to wash sprayers. At INES a PV based energy supply for the photocatalytic cleaning system was developed within the framework of two bachelor theses and assembled as a demonstration unit. Then the system was step by step extended with the process automation and pushed to a remote operating device. The final system is now available as a mobile unit mounted on a lab table. The latest step was the photocatalytic reactor module which completed the first PHOTOPUR prototype. The system is actually undergoing an intensive testing phase with performance checks at the consortium partners. First results give a good overview about the successful operation.

description: Luminescent Solar Concentrators (LSCs) have the potential for use in greenhouse roof panels to produce electricity while increasing agricultural productivity. Given that LSCs do not exhibit a perfect light trapping, part of the fluorescence light exits through the escape cone enriching the transmitted spectrum in the fluorescence band. This work concerns the evaluation of LSCs as modular devices for greenhouse building hence both the performances of LSC modules as well as the influence of this devices on basil seedlings growth was assessed. The LSC prototypes evaluated showed efficiencies ranging from 1.23 to 0.85% which, given the large surfaces involved by greenhouses, are sufficient to provide ventilation or provide water pumping. Basil seedlings were grown for three weeks under different LSC covers which in the case of red dyed LSC resulted in improved growth and health comparing to the seedlings grown under transparent PMMA.

description: Background: Posttraumatic stress disorder (PTSD) is a serious and debilitating disorder that can develop following exposure to a traumatic event. Where parents develop PTSD, it may have an impact on their parenting role. Objective: The objective was to review the existing evidence base on parental PTSD, examining whether parental PTSD has an impact on key parenting domains. Method: A comprehensive web-based search identified 27 quantitative studies that examined parental PTSD in relation to parenting domains. Results: Several parenting domains were investigated including: parenting satisfaction, parenting stress, the parent–child relationship, and specific parenting practices. Sample sizes ranged from 19 to 3931 parents. A range of parental traumas were investigated, including traumatic birth experiences, military trauma, and intimate partner violence. Findings indicated associations between parental PTSD and several domains of parenting, but there were inconsistencies across studies. Conclusions: Findings suggested that parental PTSD is associated with impaired functioning across a number of parenting domains, including increased levels of parenting stress, lower parenting satisfaction, less optimal parent–child relationships, and more frequent use of negative parenting practices, such as overt hostility and controlling behaviours. However, methodological limitations across the literature as a whole limited the potential to infer causal impacts of PTSD on parenting. Further study is also needed to advance our current understanding around the impact of different trauma types on parenting domains. • The review brought together existing evidence in the parental PTSD literature, to further understand how parental PTSD impacts parenting domains.• A total of 27 articles were reviewed, examining several parenting domains including: parenting satisfaction, parenting stress, the parent–child relationship, and specific parenting practices.• Parents with PTSD may experience more impaired functioning in these specific domains compared to parents without PTSD.• Methodological limitations across the literature limit potential inference from the current findings; therefore further study is still needed.

description: The name of Fritz Rougemont (1904-1941) is known to Warburg scholars because he appears as a co-editor, together with Gertrud Bing, of the edition of Aby Warburg’s Gesamellte Schriften, published in Leipzig by the publisher Teubner in 1932. Since 1927 Rougemont had actively collaborated with the Kulturwissenschaft Bibliothek Warburg, but later his biographical events, and in particular his adhesion to Nazism, caused a definitive damnatio memoriae of his figure, also erasing the traces of his scholarly activity almost completely. We present here an important contribution of his published in 1930 in the first volume of “Imprimatur”, the Annuary of the “Gesellschaft der Bücherfreunde zu Hamburg”. The essay, hitherto neglected in the extensive literature of Warburgian studies, is presented in a new edition of the original German version of 1930, and in the first English and Italian translations. Rougemont’s contribution represents a primary testimony of the specifically scientific meaning of Warburg’s “bibliophily”, which originally illuminates his unprecedented method of study, the analysis of the mechanisms of the Classical tradition, and the innovative trajectory of his research with respect to his contemporary, and dominant, disciplinary dictates.

description: Let $G \curvearrowright X$ be a nonelementary action by isometries of a hyperbolic group $G$ on a hyperbolic metric space $X$. We show that the set of elements of $G$ which act as loxodromic isometries of $X$ is generic. That is, for any finite generating set of $G$, the proportion of $X$--loxodromics in the ball of radius $n$ about the identity in $G$ approaches $1$ as $n \to \infty$. We also establish several results about the behavior in $X$ of the images of typical geodesic rays in $G$; for example, we prove that they make linear progress in $X$ and converge to the Gromov boundary $\partial X$. Our techniques make use of the automatic structure of $G$, Patterson--Sullivan measure on $\partial G$, and the ergodic theory of random walks for groups acting on hyperbolic spaces. We discuss various applications, in particular to Mod(S), Out($F_N$), and right--angled Artin groups.

description: Floating Photovoltaic (FPV) has recently gained a large interest worldwide, essentially as a result of promoting unused land to generate electricity. Like ground-mounted PV projects, FPV feasibility is bound to the power production estimation. Considering a production gain of 0.4% per °C for silicium cells, in addition of cooler local climate over waterbodies, predicting the thermal behavior of PV modules through modelling system arises as a stepping-stone of the next FPV commercial stage. In that context, EDF has launched a floating structure with numbers of high-frequency sensors in order to catch the evolution of interesting physical parameters, contrasting with parameters encountered over ground-mounted structures. To support previous research under tropical conditions, six months of data have been gathered during a cold period of temperate area. Discernable cooling effects were less frequent and profited of lower magnitude in such area. In addition, waterbody physical behavior was highlighted as an important catalyst of module temperature behavior. Thus, global climate conditions emerged as a key factor of cooling effect estimation for FPV. Finally, predicting module temperature has been managed through existing thermal model including in the in-house 3D-ray tracing software PVNOV.

description: Designing with photovoltaics is the core focus of this paper which presents the results of a design study on conceptual PV applications for electric mobility systems. This is a relevant direction for new product development because PV technology can contribute to improved features of electric mobility systems not just in terms of CO2 emissions reduction but also regarding product aesthetics and user experiences. Design studies are multidisciplinary by nature, therefore in this case technical, user, regulatory and aesthetic aspects are covered. Eleven conceptual designs were developed in 2019 by means of a design project executed at the University of Twente, encompassing solutions for PV-powered charging of electric vehicles, vehicle-integrated PV products and other applications. The concepts focus on various modes of transport beyond passenger cars such as public transportation, electric bicycles and utility vehicles, in some cases applying alternative charging technologies such as battery swapping and induction charging in their design. In this paper four of these conceptual designs are presented as case studies, showing their multidisciplinary focus as well as parts of the design process behind their development. An evaluation of these conceptual designs revealed several design challenges that need to be addressed in their development, including the limited space available for integrating PV cells, the technical limitations posed by some of the proposed charging methods and the effective visual communication of the concept’s intended function.

description: In building-integrated photovoltaics or BIPV, the solar cell module not only functions as energy source, but also acts as a structural element of the building. Curtain wall elements are abundantly applied in the construction sector and are particularly suitable for BIPV applications. Unfortunately, electrical cables must connect the outside solar module to the inside inverter, breaking the thermal envelope of the building. This creates a number of problems such as the creation of thermal bridges, condensation and water ingress. By means of inductive wireless power transfer, the energy from the solar module can be transferred over the insulation to the inverter, without breaking the thermal envelope. In this work, we present a wireless prototype BIPV system, designed for curtain wall elements, that applies inductive wireless power transfer. Measurements show that the system performs adequate for variable input power conditions, a prerequisite considering irregular solar radiation. Among others, we demonstrate experimentally that having a higher load resistance increases the voltage gain, while not significantly decreasing efficiency when operating at the optimal frequency. This can reduce stress on the voltage converters.

description: This paper presents a novel 3D agrovoltaic modelling tool developed in python which enables technical and economical evaluation of potential agrovoltaic designs. It has been designed and applied for fruit crops which typically have a crucial flowering period. To illustrate the potential of this tool, a case study for pear trees in Bierbeek, Belgium is shown. While many geometrical parameters of agrovoltaic systems are fixed in practice, however, there is also the need to model the impact of PV modules on the tree light interception. The results of the modelling show that the amount of solar radiation depends on the modules used, with semi-transparent modules offering better light distribution and reduced crop loss. Based on the modelling, a prototype agrovoltaic set-up with pear trees and semitransparent modules has been built in Bierbeek, Belgium.

description: An effective self-consistent model is derived and used to study the dynamics of an electron gas confined in a nonparabolic and anisotropic quantum well. This approach is based on the equations of quantum hydrodynamics, which incorporate quantum and nonlinear effects in an approximate fashion. The effective model consists of a set of six coupled differential equations (dynamical system) for the electric dipole and the size of the electron gas. Using this model we show that: (i) High harmonic generation is related to the appearance of chaos in the phase space, as attested by related Poincaré sections; (ii) Higher order harmonics can be excited efficiently and with relatively weak driving fields by making use of chirped electromagnetic waves.

description: Building Integrated Photovoltaic (BIPV) systems aim not only to generate part of the electricity consumed by the edifice, but also to reduce the environmental impact, such as the Green House Gases emissions produced by the generation of electricity by fossil fuels and the land area that would be required when installed the PV devices in floor. Nevertheless, the thermal behaviour of the PV modules has an impact into the indoor temperature of the building. To study the thermal effect produced by the environmental factors into the module temperature, Artificial intelligence, i.e. Genetic Programming (GP), is applied to one year of data of crystalline silicone PV modules mounted as building elements at outdoor operating conditions to get the model which best describes the thermal behaviour. Two well-known models guided the algorithm, the ones proposed by Ross and by Sandia Laboratories. From the application of Genetic Programming, a model was obtained which calculates the module temperature with less than 1% error. Six constants parameters are obtained for the thermal behaviour of crystalline silicon PV technology, fitting an equation whose structure reflects the two well-known models of Ross and Sandia.
Elastocapillarity: Surface Tension and the Mechanics of Soft Solids

description: It is widely appreciated that surface tension can dominate the behavior of liquids at small scales. Solids also have surface stresses of a similar magnitude, but they are usually overlooked. However, recent work has shown that these can play an central role in the mechanics of soft solids such as gels. Here, we review this emerging field. We outline the theory of surface stresses, from both mechanical and thermodynamic perspectives, emphasizing the relationship between surface stress and surface energy. We describe a wide range of phenomena at interfaces and contact lines where surface stresses play an important role. We highlight how surface stresses causes dramatic departures from classic theories for wetting (Young-Dupré), adhesion (Johnson-Kendall-Roberts), and composites (Eshelby). A common thread is the importance of the ratio of surface stress to an elastic modulus, which defines a length scale below which surface stresses can dominate.

description: Photovoltaics (PV) are promoted as an environmentally friendly alternative to carbon intensive energy sources, however, typical installations require expansive land-use. Building-integrated and building-applied photovoltaics (BIPV and BAPV) minimize this impact by use of pre-existing and non-productive surfaces for module installation. In these environments higher operating temperatures are expected because of reduced rear-side ventilation, which will have an impact on performance both instantaneously and in the long-term (i.e. reliability). A test station of 18 modules mimicking typical topologies for BIPV and BAPV was constructed in Neuchâtel (Switzerland) to monitor the thermal behavior of modules for validation of temperature predictions and modelling of degradation. Back-of-cell and back-of-module temperatures were measured by integrated thermocouples, and three factors were explored, including 1) module glass thickness (3.2-mm and 6-mm); 2) insulation (insulated, close-roof, and open-rack); and 3) inclination (0°, 45°, and 90°). Insulated and slope-mounted modules experienced the highest average temperatures and diurnal temperature differences across the year, though seasonal variations and other nuances were observed. Once long-term data sets are obtained, they will be utilized to validate temperature calculation models and model thermal and photothermal degradation of PV modules.

description: Background: According to clinical guidelines, trauma-focused psychotherapies (TF-PT) such as trauma-focused cognitive behavioural therapy (TF-CBT) and eye movement desensitization and reprocessing (EMDR) are recommended as first-line treatments for posttraumatic stress disorder (PTSD). TF-CBT and EMDR are equally effective and have large effect sizes. However, many patients fail to respond or have comorbid symptoms or disorders that only partially decline with TF-PT. Thus, there is growing interest in augmenting TF-PT through adjuvant interventions. Objective: The current systematic review aims to assess whether adjuvant interventions improve outcome among adult PTSD patients receiving TF-PT. Methods: We searched the databases PubMed, PILOTS, Web of Science and the Cochrane Library for controlled clinical trials examining whether adjuvant interventions lead to more symptom reduction in adult PTSD patients receiving TF-PT. Thirteen randomized controlled trials fitted the inclusion criteria. These were evaluated for internal risk of bias using the Cochrane Handbook for Systematic Review of Interventions. Results: Most studies have a substantial risk for internal bias, mainly due to small sample sizes. Thus, no strong conclusion can be drawn from the current empirical evidence. Preliminary evidence suggests that exercise and cortisol administration may have an adjuvant effect on PTSD symptom reduction. Breathing biofeedback showed a trend for an adjuvant effect and an effect for accelerated symptom reduction. Conclusions: Currently, it is not possible to formulate evidence-based clinical recommendations regarding adjuvants interventions. While several adjuvant interventions hold the potential to boost the effectiveness of TF-PT, the realization of sufficiently powered studies is crucial to separate plausible ideas from interventions proven to work in practice. • Assessment whether adjuvant interventions improve outcome among adult PTSD patients receiving trauma-focused psychotherapy.• No evidence-based recommendations can currently be given.• Several adjuvant interventions are promising.• Further research is needed.
