description: Background Research on abusive head trauma (AHT) is usually research on clinically identified cases, while population-based studies, having the potential to identify cases of shaking that did not end with hospital admission, are missing to date. Objective Thus, we aimed to assess the prevalence of AHT and associated risk factors in a representative sample of the German population. Participants and setting We conducted a cross-sectional, observational study in Germany from July to October 2021. Using different sampling steps including a random route procedure, a probability sample of the German population was generated. The final sample consisted of 2503 persons (50.2 % female, mean age: 49.5 years). Methods Participants were asked about sociodemographic information in a face-to-face interview and whether they had been ever responsible for the care of an infant and whether they had ever performed potential harmful methods including shaking to calm it, intimate partner violence (IPV) and adverse childhood experiences (ACEs) using a questionnaire. Results In total, 1.4 % of women (N = 18) and 1.1 % of men (N = 13) reported to have at least once shaken an infant to calm it. Ever having used a potential harmful parenting method in calming an infant was reported by 4.9 % of women (N = 61) and 3.1 % (N = 39) of men. No gender differences were seen. A low income, living with someone under 16 in the household and victimization and perpetration of IPV and ACEs are associated with increased risks of shaking and other potential harmful methods to calm an infant. Conclusions Our data suggest that despite better knowledge on the dangers of shaking, the percentage of women that shake infants might be higher than previously thought. Also, intimate partner violence and ACEs are key risk factor for shaking and harmful parenting behaviors in general. This has important implications for future prevention programs.

description: We show how to test the bipartiteness of an intersection graph of n line segments or simple polygons in the plane, or of balls in R^d, in time O(n log n). More generally we find subquadratic algorithms for connectivity and bipartiteness testing of intersection graphs of a broad class of geometric objects. For unit balls in R^d, connectivity testing has equivalent randomized complexity to construction of Euclidean minimum spanning trees, and hence is unlikely to be solved as efficiently as bipartiteness testing. For line segments or planar disks, testing k-colorability of intersection graphs for k>2 is NP-complete.

description: The Euphorbiaceae family, known for its capacity of being used as medicinal and biopecticide, has attracted great attention in recent years. In this study, the genotoxic and cytotoxic effects of Euphorbia rigida Bieb. aqueous extract, believed to have the capacity of being used as biopecticide in both medicinal and agricultural applications, were determined with the Allium test. According to Allium test results, it had negative impacts on mitosis and showed cytotoxic and genotoxic effects for the cells existing here. The lowest level of MI (2.95 %) was observed in the 200 ppm treatment of E. rigida extract. On the other hand the highest number of aberrant cells was observed in pesticide Elandor® treatment with 88.1 aberrant cells, followed by the 50 ppm E. rigida extract with 84.1 and pesticide Goldplan® treatment with 82.5 aberrant cells. The highest cytological anomalies were chromosome stickiness, irregular metaphase and anaphase, pole deviations and C-mitosis. Antiviral activity properties of euphorbia diterpenoids, triterpenoids and steroids are known. We think that E. rigida plant extracts will have strong cytotoxic and genotoxic effects on the DNA/RNA and capsid structures of viruses. This may mean that they can be used as additives as a disinfectant for inanimate surfaces and social areas in addition pharmaceutics industry. In addition, according to the results obtained in our research, we can suggest that the extract obtained from E. rigida plant with water up to 50 ppm can be used as an alternative to chemicals used biopestisit purposes. No matter what purposes the extract of this plant is used, great care should be taken while using it because it can cause damage on cells and chromosomes. Hence, through more detailed and comprehensive studies, its capacity for medical and biopestisit purposes should be investigated.

description: In this paper, we derive a new model for the description of liquid crystalline flows. While microscopic Doi type models suffer from the high dimensionality of the underlying product space, the more macroscopic Ericksen--Leslie type models describe only the long time behavior of the flow and are valid only close to equilibrium. By applying an energetic variational approach, we derive a new macroscopic model which shall provide an improved description far from equilibrium. The novelty of our approach lies in the way the energy is minimized. Distinguishing between the velocities of particles and fluid allows us to define the energy dissipation not in terms of chemical potentials but in terms of friction induced by the discrepancies in the considered velocities. We conclude this publication by establishing the existence of weak solutions to the newly derived model.

description: Polyglot Cubed is an educational game to facilitate the learning of multiple languages. It is designed to entertain while enforcing language listening comprehension. The modular language learning game system works interchangeably with a variety of languages. The game relies on a matching mechanic intended to balance comprehension based language recognition with a simple gameplay mechanic. The game is an implementation of theories in motivation, education and entertainment. It takes as its motivation academic critique of existing educational video games and in particular pursues those areas where educational games fall short of the needs of post-secondary learners. This document outlines the research, design, implementation and fundamental evaluation of the educational video game.

description: Music Box is an artistic implementation of emergent behavior and its use to create music. Music Box employs Craig Reynold’s flocking algorithm to display animated notes that rise from a written score, then move to create a distinctive flock-lead musical arrangement. The result is emergent sound; a musical arrangement directed by the visual representation of flocking. The goal of this creative exploration is to free the musical score from the prevalent model of composer, performer and listener supported by standard models. Instead the experience is more democratic. Here the composer suggests, the performer follows a few loose rules, and the listener plays with the composition. This is accomplished through the development of artificial intelligence software that applies the visual rules of flocking behaviors to the algorithmic arrangement of musical pitches. Importantly, these visual rules are manipulated by the software user resulting in a dual performance and composition. The result is musical authoring based on the user model of computer video games.

description: We investigate the relationship between emission-line strength and continuum luminosity in the best-studied nearby Seyfert 1 galaxy NGC5548. Our analysis of 13 years of ground-based optical monitoring data reveals significant year-to-year variations in the observed H-beta emission-line response in this source. More specifically, we confirm the result of Gilbert and Peterson (2003) of a non-linear relationship between the continuum and H-beta emission-line fluxes. Furthermore, we show that the slope of this relation is not constant, but rather decreases as the continuum flux increases. Both effects are consistent with photoionisation model predictions of a luminosity-dependent response in this line.

title: Mechanisms of tigecycline resistance in the Enterobacteriaceae and Acinetobacter baumannii
Creators: name: Hornsey, Michael Andrew
Publisher: name: The Open University
Year: 2011

description: Tigecycline is the first glycylcycline to enter clinical use and displays good in vitro activity against a broad range of Gram-positive and Gram-negative pathogens. It is often used as an agent of last resort for the treatment of infections caused by multidrug-resistant Gram-negative bacteria including some Enterobacteriaceae species and Acinetobacter baumannii. Therefore, the recent emergence of tigecycline resistance in some strains of these species is a serious public health concern. Efflux was investigated as a possible mechanism of tigecycline resistance using pre- and post-therapy pairs of clinical isolates and laboratory-selected, tigecycline-resistant mutants of A. baumannii and Enterobacter cloacae and a type strain, laboratory mutants, and a clinical isolate of Serratia marcescens. Minimum inhibitory concentrations (MICs) of tigecycline and other agents were determined by agar dilution. Pulsed-field gel electrophoresis was used to assign clones / determine isolate relatedness. Expression of efflux pump genes and genes thought to be implicated in their regulation was monitored by real-time reverse-transcriptase polymerase chain reaction and their role in tigecycline resistance was further investigated by knockout mutagenesis. There was an association between increased expression of specific resistance-nodulation-division (RND) efflux pump genes and elevated tigecycline MICs in all species studied. Insertional inactivation of RND efflux pump genes implicated the AdeABC, AcrAB and SdeXY-HasF systems of A. baumannii, E. cloacae and S. marcescens, respectively. The results of this study support the hypothesis that tigecycline resistance in clinical isolates of Gram-negative bacteria arises as a result of the up-regulated activity of intrinsic efflux systems of the RND family.

description: From random matrix theory it is known that for special values of the coupling constant the Calogero-Moser (CM) equation system is nothing but the radial part of a generalized harmonic oscillator Schroedinger equation. This allows an immediate construction of the solutions by means of a Rodriguez relation. The results are easily generalized to arbitrary values of the coupling constant. By this the CM equations become nearly trivial. As an application an expansion for in terms of eigenfunctions of the CM equation system is obtained, where X and Y are matrices taken from one of the Gaussian ensembles, and the brackets denote an average over the angular variables.

description: We consider the power functions of five popular tests for AR(1) errors in a linear regression model from which relevant regressors have inadvertently been omitted. These functions are derived by numerically evaluating the finite-sample distributions of the test statistics. With this form of model mis-specification, it is found that the performances of the tests are not independent of the scale of the errors' distribution. The omission of seasonal effects or a linear trend component can have serious implications, especially if testing against positive autocorrelation, and some of the well known advantages of the "Alternative Durbin Watson test" (King (1981)) are found to still apply when the model is underspecified.

The circuit consists of four three-junction flux qubits, with simultaneous ferro- and antiferromagnetic coupling implemented using shared Josephson junctions. Its response, which is dominated by the ground state, is characterized using low-frequency impedance measurement with a superconducting tank circuit coupled to the qubits. The results are found to be in excellent agreement with the quantum-mechanical predictions.

description: The present investigation was undertaken to examine the geographic distributions of cytotypes of Saccharum spontaneum L., wild species of sugarcane, in India. New chromosome determinations has been done for 524 accessions collected mainly from four ecological zones, West, East, North and North-east, of the country. A detailed evaluation of cytogeographic pattern of S. spontaneum has been done with these clones along with the clones in which chromosome data is already available. Twenty six cytotypes ranging from 2n=40 (8x) to 2n=112 (14X) has been identified in S. spontaneum from India. Gangetic valley of Sub Himalayan region and deltaic region of South-east zone can be considered as regions of cytogeographic interest with largest concentration of different chromosome numbers. North-east region of the country appears to have had a higher evolutionary activity in this species which is evidenced by the occurrence of multiple cytotypes and sympatric growth with other species and genera. The overall cytogeographic pattern of S. spontaneum includes the incidence of mixed polyploidy, aneuploidy, sympatric with different ploidy levels and disjunct distribution of some cytotypes indicate that this species likely to have had multiple independent origin in different parts of India.

description: We calculate the quark distribution function for 3He/3H in a relativistic quark model of nuclear structure which adequately reproduces the nucleon approximation, nuclear binding energies, and nuclear sizes for small nuclei. The results show a clear distortion from the quark distribution function for individual nucleons (EMC effect) arising dominantly from a combination of recoil and quark tunneling effects. Antisymmetrization (Pauli) effects are found to be small due to limited spatial overlaps. We compare our predictions with a published parameterization of the nuclear valence quark distributions and find significant agreement.

description: The Mediterranean dwarf palm (Chamaerops humilis L.) is native to Western and Central Mediterranean. Since classical times this species has been cultivated and several varieties have been described on material of unknown origins. In this study, plants grown from seeds collected in the wild from seven populations spread along the Mediterranean basin were cultivated under the same environmental conditions, investigated morphologically and genetically by screening the polymorphism of ten SSR loci. Two groups are clearly separated, the populations growing at low altitudes and those living above a thousand meters of altitude. Due to morphological, geographic and environmental isolation, here it is proposed to discriminate the populations growing at high altitude on the Moroccan High Atlas and Anti-Atlas as a distinct subspecies.

description: In the machine learning era, sparsity continues to attract significant interest due to the benefits it provides to learning models. Algorithms aiming to optimise the \(\ell_0\)- and \(\ell_1\)-norm are the common choices to achieve sparsity. In this work, an alternative algorithm is proposed, which is derived based on the assumption of a Cauchy distribution characterising the coefficients in sparse domains. The Cauchy distribution is known to be able to capture heavy-tails in the data, which are linked to sparse processes. We begin by deriving the Cauchy proximal operator and subsequently propose an algorithm for optimising a cost function which includes a Cauchy penalty term. We have coined our contribution as Iterative Cauchy Thresholding (ICT). Results indicate that sparser solutions can be achieved using ICT in conjunction with a fixed over-complete discrete cosine transform dictionary under a sparse coding methodology.

description: Epoxiconazole belongs in the class of azoles which have been developed to protect crops from fungal diseases. The mechanism of action of these fungicides is to inhibit the specific cytochrome P450 enzyme (CYP), CYP51 (lanosterol 14α-demethylase) which contributes to ergosterol biosynthesis. Since ruminants and cattle are exposed to contaminants during grazing, they are a suitable experimental model for genotoxicity testing. In our experiment, epoxiconazole (EPX) (active agent, 99% of purity) was tested in vitro for its potential genotoxic and cytotoxic effects on bovine lymphocytes, isolated from whole peripheral blood. We exposed the lymphocytes to EPX at concentrations of 2.5, 5, 10, 25, 50 and 100 μg/mL by two different ways: immediately after isolation of lymphocytes during 2 h in RPMI 1640 medium (without phytohaemagglutinin, PHA) as well as on the last 2 h of 48-h culture (with PHA). In a second case, we chose 48 h culture because the lymphocytes usually start DNA replication 24 h after the start of the cultures; therefore, we incubated the cells longer to obtain dividing (proliferating) cells. The levels of DNA damage were measured using alkaline and neutral comet assays. The results of alkaline comet assay showed the significantly increased percentage of DNA breaks in both lymphocytes in medium without PHA (2 h of exposure; non-proliferating cells) and lymphocytes cultured during 48 h in medium with PHA (exposure for the last 2 h of cultivation; proliferating cells). Similarly, neutral comet assay showed dose-dependent elevation of the DNA migration induced in both non-proliferating and proliferating lymphocytes treated with EPX when compared with negative controls. Our results suggest that epoxiconazole fungicide is capable of causing damage to the genetic material of the bovine cells.

description: Grasshoppers, specifically those of the family Acrididae are known to have the largest genomes of all insects. However, less than 100 species of Orthoptera have their genome size estimated so far. In the present study, we measured the genome size of five acridid species belonging to the two subfamilies Oedipodinae and Gomphocerinae. All of the genomes measured are large and ranges between 1C = 11.31 pg in the female of Chorthippus dorsatus and 1C = 18.48 pg in the female of Stethophyma grossum. The latter represents the so far largest measured insect genome. We further provide a summary of genome size estimates available for Orthoptera.

Year: 2023

description: This case study outlines a methodology for adapting digital games from literature. The process maps key narrative events to human computer interactions via game verbs. Game verbs are distinct player actions that help the player accomplish their in-game goal. Through the use of tightly coupled narrative events and game verbs, the game engenders the spirit of Edgar Allen Poe’s short story The Tell Tale Heart. Like the story’s protagonist, players move from controlled actions to erratic behavior as they manipulate their device. Players are required to propel the narrative through accelerometer and touch-based actions. The resulting game’s physicality is designed to match the narrative’s drive toward madness.

description: A conventional cytogenetics analysis revealed for first time an allopolyploid lineage of the genus Aeschynomene in Mexico. The hybrid condition is confirmed after all the prometaphase and metaphase nuclei of the hybrids exhibited only one pair of SAT-chromosomes, confirming the existence of nucleolar dominance and amphiplasty. The karyotype formula for this lineage was 2n = 4x = 40 = 34m + 6sm with a total diploid chromosome length (TDCL) = 28µm and an average chromosome size (AC) = 1.40µm. Comparison of the karyotype and other chromosomal parameters with recent cytogenetics records for other species of the subgenus Aeschynomene included in the Nod-independent clade allows propose to Aeschynomene evenia and A. scabra as possible progenitors. Furthermore, other comparison of seedlings focused at the number of leaflets of the first four eophylls of the proposed parents and of the hybrid individuals allowed to observe coincidences that support the proposal made from the cytogenetic analysis. Evidence of "gigas" effects on flowers and fruits of hybrids is also shown.

description: The effect of membrane viscosity on the dynamics of vesicles in shear flow is studied. We present a new simulation technique, which combines three-dimensional multi-particle collision dynamics for the solvent with a dynamically-triangulated membrane model. Vesicles are found to transit from steady tank-treading to unsteady tumbling motion with increasing membrane viscosity. Depending on the reduced volume and membrane viscosity, shear can induce both discocyte-to-prolate and prolate-to-discocyte transformations. This dynamical behavior can be understood from a simplified model.

description: Affection games are ludic experiences in which players are required to express culturally recognized expressions of liking as a primary goal in the game. Interestingly, while the physical world of analog play has many such activities, the digital world has been relatively limited in affording players the ability to express affection as the primary game goal. Affection games in digital play exist as somewhat esoteric clusters across a variety of cultures and super genres. This paper defragments the diverse set of affection games, collecting, cataloging and describing the games in detail. The paper provides a content analysis of affection games and an overview of their preponderance on the web. This paper organizes affection games into a simple classification based on their game verbs. These are flirting, hugging, kissing, and sexual affection. The content analysis provides the attributes through which the affection games are clustered. Notable patterns from the content analysis include indications that kissing and sexual affection are most common, while hugging games are the rarest. There is also a strong coupling of targeted gender identification and the types of affection made playable. These patterns are indicated both in the spaces in which they are distributed and in their content. As the game industry and the academic research community look for new ways to understand and engage wider demographics, the lessons learned from studying affection games may prove useful. Affection games reveal cultural values, taboo, and may potentially expand the space of pro-social play.

description: Global equilibrium fragmentation inside a freeze out constraining volume is a working hypothesis widely used in nuclear fragmentation statistical models. In the framework of classical Lennard Jones molecular dynamics, we study how the relaxation of the fixed volume constraint affects the posterior evolution of microscopic correlations, and how a non-confined fragmentation scenario is established. A study of the dynamical evolution of the relative kinetic energy fluctuations was also performed. We found that asymptotic measurements of such observable can be related to the number of decaying channels available to the system at fragmentation time.

description: Materials Cloud is a platform designed to enable open and seamless sharing of resources for computational science, driven by applications in materials modelling. It hosts 1) archival and dissemination services for raw and curated data, together with their provenance graph, 2) modelling services and virtual machines, 3) tools for data analytics, and pre-/post-processing, and 4) educational materials. Data is citable and archived persistently, providing a comprehensive embodiment of the FAIR principles that extends to computational workflows. Materials Cloud leverages the AiiDA framework to record the provenance of entire simulation pipelines (calculations performed, codes used, data generated) in the form of graphs that allow to retrace and reproduce any computed result. When an AiiDA database is shared on Materials Cloud, peers can browse the interconnected record of simulations, download individual files or the full database, and start their research from the results of the original authors. The infrastructure is agnostic to the specific simulation codes used and can support diverse applications in computational science that transcend its initial materials domain.

description: The structure and chemistry of protoplanetary disks depends strongly on the nature of the central star around which it has formed. The dust temperature is mainly set by the stellar luminosity, while the chemistry of the upper disk layers depends on the amount of intercepted UV and X-ray flux. We will study the differences in chemistry, thermal sturcture and line emission around Herbig Ae/Be, T Tauri stars and low mass M dwarfs. Predictions will be made for future observations with SOFIA and Herschel.

description: Oecidiophilus Silvestri, 1946
 Oecidiophilus Silvestri, 1946: 331.
 Type species: Oecidiophilus mimellus Silvestri, 1946, by monotypy (not O. oglobinii, nomen nudum, as originally designated by Silvestri, 1946).
 Redescription: Head elongate, about 1.4 times as long as wide, not widest behind the eyes; gula narrow, lateral margins almost parallel; foramen magnum broad, about one third the head width; mandibles symmetrical; maxillary palpi with 4 palpomeres, fourth palpomere almost the length of the third; prementum with palpi with 3 palpomeres, and ligula slightly incised in the middle; antennae with 11 antennomeres, scape as long as antennomeres II and III combined, III‑X slightly longer than wide, progressively and slightly decreasing in length towards apex.
 Thorax: Wings present and broken; first metatarsomere as long as second and third combined.
 Abdomen highly physogastric and scarcely setose, covered mostly by short and medium bristles; tergite IX without macrosetae; tergite X suboval, with midsized bristles at apex. Aedeagus with phallobase large and bulbous, apex of median lobe with membranous structure with sinuous pattern.
 Remarks: The genus Oecidiophilus until now was represented by a single enigmatic species from Argentina, Loreto (Misiones), known only from the holotype and the original description (Silvestri, 1946). Herein, the second species of the genus is described, representing the first record of Oecidiophilus for Brazil. The wings of the analyzed specimen were broken in a similar way to that found in Fonsechellus species.It is presumed that individuals lose their wings in the same way as Fonsechellus and it would not be impressive if this phenomenon was even more embracing across other related genera in the subtribe Termoiceina.

Magnetic frustration in a stoichiometric spin-chain compound, Ca$_3$CoIrO$_6$

description: The temperature dependent ac and dc magnetization and heat capacity data of Ca$_3$CoIrO$_6$, a spin-chain compound crystallizing in a K$_4$CdCl$_6$-derived rhombohedral structure, show the features due to magnetic ordering of a frustrated-type below about 30 K, however without exhibiting the signatures of the so-called "partially disordered antiferromagnetic structure" encountered in the isostructural compounds, Ca$_3$Co$_2$O$_6$ and Ca$_3$CoRhO$_6$. This class of compounds thus provides a variety for probing the consequences of magnetic frustration due to topological reasons in stoichiometric spin-chain materials, presumably arising from subtle differences in the interchain and intrachain magnetic coupling strengths. This compound presents additional interesting situations in the sense that, ac susceptibility exhibits a large frequency dependence in the vicinity of 30 K uncharacteristic of conventional spin-glasses, with this frustrated magnetic state being robust to the application of external magnetic fields.

description: In regression analysis we are often interested in using an estimator which is "precise" and which simultaneously provides a model with "good fit". In this paper we consider the risk properties of several estimators of the regression coefficient vector under "balanced" loss. This loss function (Zellner (1991)) reflects both of the above attributes. Under a particular form of balanced loss, we derive the predictive risk of the pre-test estimator which results after a test for exact linear restrictions on the coefficient vector. The corresponding risks of a Stein-rule and positive-part Stein-rule estimators are also established. The risks based on loss functions which allow only for estimation precision, or only for goodness of fit, are special cases of our results, and we draw appropriate comparisons. In particular, we show that some of the well-known results under (quadratic) precision-only loss are not robust to our generalisation of the loss function.

description: We analyze the action $\int d^4x \sqrt{\det||{\cal B} g_{μν}+ {\cal C} R_{μν}}||$ as a possible alternative or addition to the Einstein gravity. Choosing a particular form of ${\cal B}(R)= \sqrt {R}$ we can restore the Einstein gravity and, if ${\cal B}=m^2$, we obtain the cosmological constant term. Taking ${\cal B} = m^2 + {\cal B}_1 R$ and expanding the action in $ 1/m^2$, we obtain as a leading term the Einstein Lagrangian with a cosmological constant proportional to $m^4$ and a series of higher order operators. In general case of non-vanishing ${\cal B}$ and ${\cal C}$ new cosmological solutions for the Robertson-Walker metric are obtained.

Awn microstructural observation revealing multifunction of awn-inhibitor Gene B1 in near-isogenic lines with different awn length
Creators: name: Li, Xingfeng

description: Awn is one of wheat morphological characteristics and acts as a highly effective organ for photosynthesis in wheat. Variation in awn length is controlled primarily by three major genes, most commonly the dominant awn suppressor Tipped1 (B1). So far, the function of B1 is not well understood. In this paper, we identified a pair of near-isogenic lines (NILs) containing different awn inhibition gene B1 alleles and observed microstructures and ultra-microstructure of their awns. The typical awns differences between the NILs represented by the cross-sectional area and chloroplasts number. Long awn line had a larger cross-sectional area, and more cells in various parts of tissues, especially the cells containing more and larger chloroplasts, which could attribute to a strong cytological basis for photosynthesis. The results may suggest that the gene has pleiotropic effects in the control development of awn tissue structure and grain yield.

General criteria for quantum state smoothing with necessary and sufficient criteria for linear Gaussian quantum systems

description: Quantum state smoothing is a technique for estimating the quantum state of a partially observed quantum system at time $τ$, conditioned on an entire observed measurement record (both before and after $τ$). However, this smoothing technique requires an observer (Alice, say) to know the nature of the measurement records that are unknown to her in order to characterize the possible true states for Bob's (say) systems. If Alice makes an incorrect assumption about the set of true states for Bob's system, she will obtain a smoothed state that is suboptimal, and, worse, may be unrealizable (not corresponding to a valid evolution for the true states) or even unphysical (not represented by a state matrix $ρ\geq0$). In this paper, we review the historical background to quantum state smoothing, and list general criteria a smoothed quantum state should satisfy. Then we derive, for the case of linear Gaussian quantum systems, a necessary and sufficient constraint for realizability on the covariance matrix of the true state. Naturally, a realizable covariance of the true state guarantees a smoothed state which is physical. It might be thought that any putative true covariance which gives a physical smoothed state would be a realizable true covariance, but we show explicitly that this is not so. This underlines the importance of the realizabilty constraint.

description: The production of $η$ mesons in $NN$ collisions in the near threshold region is analyzed with special emphasis on the role of final state interaction which is calculated using three-body scattering theory. The three-body aspects are shown to be very important in interpreting experimental results for the total cross section of $pp\toηpp$. Furthermore, energy spectra and angular distributions of the emitted particles are calculated and compared to experimental data.
