description: Variation and disparity in resource access between individuals in an animal population within human-dominated landscapes require attention as artificial selection processes may be at work. Independent, recreational human-wildlife feeding interactions constitute an increasingly prevalent, yet understudied, food resource for birds and mammals living in our cities. However, only a limited number of risk-taking individuals may access it. Using urban fallow deer as our model species, we hypothesized that if these interactions result in positive effects for the engaging individual, e.g. increased milk quality and yield, then this would result in the increased growth rates of their offspring. Alternatively, if these individuals were prioritizing investing time in engagement with humans, resulting in decreased maternal care, then this would result in slower growth rates in their offspring. We found that the offspring of those females that regularly interacted with humans displayed significantly faster growth rates than their risk-adverse counterparts. This advantage for fearless mothers in terms of boosted neonatal growth rates could be mirrored in birds accessing garden feeders, seagulls or pigeons utilizing urban resources, or seals approaching city harbours. Here, we add a new piece to the complex puzzle of how humans are impacting wildlife living within human-dominated landscapes.

description: We analyse the properties of the circum-galactic medium and the metal content of the stars comprising the central galaxy in eight hydrodynamical `zoom-in' simulations of disc galaxy formation. We use these properties as a benchmark for our model of galaxy formation physics implemented in the moving-mesh code AREPO, which succeeds in forming quite realistic late-type spirals in the set of `Aquarius' initial conditions of Milky Way-sized haloes. Galactic winds significantly influence the morphology of the circum-galactic medium and induce bipolar features in the distribution of heavy elements. They also affect the thermodynamic properties of the circum-galactic gas by supplying an energy input that sustains its radiative losses. Although a significant fraction of the heavy elements are transferred from the central galaxy to the halo, and even beyond the virial radius, enough metals are retained by stars to yield a peak in their metallicity distributions at about $Z_{\odot}$. All our default runs overestimate the stellar [O/Fe] ratio, an effect that we demonstrate can be rectified by an increase of the adopted SN type Ia rate. Nevertheless, the models have difficulty in producing stellar metallicity gradients of the same strength as observed in the Milky Way.

description: As conversational search becomes more pervasive, it becomes increasingly important to understand the user's underlying needs when they converse with such systems in diverse contexts. We report on an insitu experiment to collect conversationally described information needs in a home cooking scenario. A human experimenter acted as the perfect conversational search system. Based on the transcription of the utterances, we present a preliminary coding scheme comprising 27 categories to annotate the information needs of users. Moreover, we use these annotations to perform prediction experiments based on random forest classification to establish the feasibility of predicting the information need from the raw utterances. We find that a reasonable accuracy in predicting information need categories is possible and evidence the importance of stopwords in the classfication task.

description: In order to achieve a high level of cyber security awareness most mid to large sized companies use Security Information and Event Management (SIEM) embedded into a Security Operations Center. These systems enable the centralized collection and analysis of security relevant information generated by a variety of different systems, to detect advanced threats and to improve reaction time in case of an incident. In this paper, we derive a generic SIEM pattern by analyzing already existing tools on the market, among additional information. Thereby, we adhere to a bottom-up process for pattern identification and authoring. This article can serve as a foundation to understand SIEM in general and support developers of existing or new SIEM systems to increase reusability by defining and identifying general software modules inherent in SIEM.

description: In this paper we present a comprehensive study of the heavy quark production in ultra high energy cosmic ray interactions in the atmosphere considering that the primary cosmic ray can be either a photon, neutrino or a proton. The analysis is performed using a unified framework -- the dipole formalism --- and the saturation effects, associated to the physical process of parton recombination, are taken into account. We demonstrate that the contribution of heavy quarks for cosmic ray interactions is in general non-negligible and can be dominant depending of the process considered. Moreover, our results indicate that new dynamical mechanisms should be included in order to obtain reliable predictions for the heavy quark production in $pp$ collisions at ultra high cosmic ray energies.

description: If dark matter particles self-interact, their capture by astrophysical objects should be enhanced. As a consequence, the rate by which they annihilate at the center of the object will increase. If their self scattering is strong, it can be observed indirectly through an enhancement of the flux of their annihilation products. Here we investigate the effect of self-interaction on the neutrino flux produced by annihilating dark matter in the center of the Sun. We consider annihilation into two channels: $W^+W^-$ (or $τ^+τ^-$ for a dark matter mass below the $W$ mass) and $b\overline{b}$. We estimate the event rate in the IceCube detector, using its 79 string configuration, and compare our prediction to their experimental results, hence probing dark matter self interacting models.

title: Synthesis and characterisation of poly(methylphenylsilane) block copolymers
Creators: name: Rossi, Nicholas Agostino Antonio
Publisher: name: University of Kent
Year: 2022

description: Samples of α,ω-dichloropoly(methylphenylsilane) (diCIPMPS) were synthesised via the Wurtz-reductive coupling polymerisation. Subsequent bromination of PMPS afforded monomodal polymers with halogenated chain ends, namely α,ω-dihalopoly- (methylphenylsilane) (diXPMPS). Condensation reactions of diXPMPS with alcohols were investigated in order to determine the reactivity of the halide end groups. Condensation reactions involving polymeric alcohols such as poly(ethylene oxide) and poly(ethylene glycol) methyl ether with diXPMPS to form amphiphilic block copolymers were attempted, but proved ultimately unsuccessful. An alternative route whereby a PMPS macroinitiator was used to form ABA block copolymers via a transformation mechanism is described. ABA block copolymers of methyl methacrylate and methylphenylsilane (PMMA-PMPS-PMMA) were synthesised using a methodology based on atom transfer radical polymerisation (ATRP). The reaction of samples of diXPMPS with 2-hydroxyethyl-2-methyl-2- bromopropanoate gave suitable macroinitiators for the ATRP of methacrylic monomers. Amphiphilic ABA block copolymers were synthesised via the polymerisation of either 2-hydroxyethyl methacrylate (HEMA) or methoxy-capped oligo(ethylene glycol) methacrylate (OEGMA). In addition, an alternative PMPS macroinitiator was synthesised to form block copolymers of styrene and methylphenylsilane via TEMPO-mediated free radical polymerisation. In this case, diXPMPS was endcapped with 2,2,6,6,-tetramethyl-l-(l-phenyl-2-hydroxyethyloxy)- piperidine to form a suitable macroinitiator. All block copolymers were characterised using 'H NMR and l3C NMR spectroscopy and size exclusion chromatography. Preliminary evidence of phase separation in samples of PMMA-PMPS-PMMA was observed via differential scanning calorimetry. The amphiphilic block copolymers were also investigated to determine their suitability for applications in three areas of research - drug delivery systems, cell growth, and bioelectronics.

description: An all-optical transistor is a device in which a gate light pulse switches the transmission of a target light pulse with a gain above unity. The gain quantifies the change of the transmitted target photon number per incoming gate photon. We study the quantum limit of one incoming gate photon and observe a gain of 20. The gate pulse is stored as a Rydberg excitation in an ultracold gas. The transmission of the subsequent target pulse is suppressed by Rydberg blockade which is enhanced by a Förster resonance. The detected target photons reveal in a single shot with a fidelity above 0.86 whether a Rydberg excitation was created during the gate pulse. The gain offers the possibility to distribute the transistor output to the inputs of many transistors, thus making complex computational tasks possible.

description: We theoretically investigate one-dimensional three-component spin-orbit-coupled Fermi gases in the presence of Zeeman field. By solving the Bogoliubov-de-Gennes equations, we obtain the phase diagram at given chemical potential and order parameter. We show that the system undergoes a phase transition from Bardeen-Cooper-Schrieffer superfluid to topological superfluid as increasing the intensity of Zeeman field. By comparing to the two-component system, we find, besides the topological phase transition from the trivial superfluid to nontrivial topological superfluid, the system can always be in a nontrivial topological superfluid, and there are two Majorana zero energy regions while increasing the magnetic field. We find the three-component spin-orbit-coupled Fermi gases in certain parameter range is more optimizing for experimental realization due to the smaller magnetic field needed. We therefore propose a promising candidate for realizing topological superfluid.

description: Constructing and adapting process models is highly relevant in today’s business world, but time-consuming and error-prone. Several approaches address these issues by manual tasks or making use of automation in the past years. Especially the research field Automated Planning envisions a (semi-)automated construction of process models by using semantic annotations and planning techniques. We aim at an empirical analysis of the influence of Automated Planning on the task performance of process modelers compared to the task performance when using common process modeling tools. We analyze the invested effort in terms of the required time for modeling tasks and the outcome in terms of the quality of the constructed process models by means of a laboratory experiment. Our findings indicate that Automated Planning significantly improves the task performance. The quality of constructed process models is increased, and especially for larger process models, the required time for modeling tasks could be decreased.

description: Magnetotransport through cylindrical topological insulator (TI) nanowires is governed by the interplay between quantum confinement and geometric (Aharonov-Bohm and Berry) phases. Here, we argue that the much broader class of TI nanowires with varying radius -- for which a homogeneous coaxial magnetic field induces a varying Aharonov-Bohm flux that gives rise to a non-trivial mass-like potential along the wire -- is accessible by studying its simplest member, a TI nanocone. Such nanocones allow to observe intriguing mesoscopic transport phenomena: While the conductance in a perpendicular magnetic field is quantized due to higher-order topological hinge states, it shows resonant transmission through Dirac Landau levels in a coaxial magnetic field. Furthermore, it may act as a quantum magnetic bottle, confining surface Dirac electrons and leading to Coulomb blockade. We show numerically that the above-mentioned effects occur for experimentally accessible values of system size and magnetic field, suggesting that TI nanocone junctions may serve as building blocks for Dirac electron optics setups.
Steering Zitterbewegung in driven Dirac systems -- from persistent modes to echoes

description: Although zitterbewegung -- the jittery motion of relativistic particles -- is known since 1930 and was predicted in solid state systems long ago, it has been directly measured so far only in so-called quantum simulators, i.e. quantum systems under strong control such as trapped ions and Bose-Einstein condensates. A reason for the lack of further experimental evidence is the transient nature of wave packet zitterbewegung. Here we study how the jittery motion can be manipulated in Dirac systems via time-dependent potentials, with the goal of slowing down/preventing its decay, or of generating its revival. For the harmonic driving of a mass term, we find persistent zitterbewegung modes in pristine, i.e. scattering free, systems. Furthermore, an effective time-reversal protocol -- the "Dirac quantum time mirror" -- is shown to retrieve zitterbewegung through echoes.

description: We have studied the field and temperature dependence of the magnetization of single crystals of Sr3NiIrO6. These measurements evidence the presence of an easy axis of anisotropy and two anomalies in the magnetic susceptibility. Neutron powder diffraction realized on a polycrystalline sample reveals the emergence of magnetic reflections below 75 K with magnetic propagation vector k ~ (0, 0, 1), undetected in previous neutron studies [T.N. Nguyen and H.-C zur Loye, J. Solid State Chem., 117, 300 (1995)]. The nature of the magnetic ground state, and the presence of two anomalies common to this family of material, are discussed on the basis of the results obtained by neutron diffraction, magnetization measurements, and symmetry arguments.

description: LiF:Mg,Ti and LiF:Mg,Cu,P are well known thermoluminescence (TL) dosimetry materials since many years. A few years ago their properties seemed well known and it was widely believed that they are not suitable for the measurement of doses above the saturation level of the TL signal, which for both materials occur at about 1 kGy. The high-dose high-temperature TL emission of LiF:Mg,Cu,P observed at the IFJ in 2006, which above 30 kGy takes the form of the so-called TL peak B, opened the way to use this material for measuring the dose in the high and ultra-high range, in particular for the monitoring of ionizing radiation around the essential electronic elements of high-energy accelerators, also fission and fusion facilities, as well as for emergency dosimetry. This discovery initiated studies of high and ultra-high dose characteristics of both of these phosphors, which turned out to be significantly different in many aspects. These studies not only strive to refine the method for measuring high doses based on the observed phenomenon, but also, and perhaps above all, bring us closer to understanding its origin and essence. This manuscript aims to review existing research data on the high and ultra-high dose features of both LiF based phosphors.

description: Spatial modulations in the distribution of observed luminosities (computed using redshifts) of ~ 5 $\times$ 10$^5$ galaxies from the SDSS Data Release 7, probe the cosmic peculiar velocity field out to z ~ 0.1. Allowing for luminosity evolution, the r-band luminosity function, determined via a spline-based estimator, is well represented by a Schechter form with M$^{\star}$(z) - 5log$_{10}$h = -20.52 - 1.6(z - 0.1) $\pm$ 0.05 and $α^{\star}$ = -1.1 $\pm$ 0.03. Bulk flows and higher velocity moments in two redshift bins, 0.02 < z < 0.07 and 0.07 < z < 0.22, agree with the predictions of the $Λ$CDM model, as obtained from mock galaxy catalogs designed to match the observations. Assuming a $Λ$CDM model, we estimate $σ_{8}$ $\approx$ 1.1 $\pm$ 0.4 for the amplitude of the linear matter power spectrum, where the low accuracy is due to the limited number of galaxies. While the low-z bin is robust against coherent photometric uncertainties, the bias of results from the second bin is consistent with the ~ 1% magnitude tilt reported by the SDSS collaboration. The systematics are expected to have a significantly lower impact in future datasets with larger sky coverage and better photometric calibration.

description: Simulation testing is an important approach to evaluating fishery stock assessment methods. In the last decade, the fisheries stock assessment modeling framework Stock Synthesis (SS3) has become widely used around the world. However, there lacks a generalized and scriptable framework for SS3 simulation testing. Here, we introduce ss3sim, an R package that facilitates reproducible, flexible, and rapid end-to-end simulation testing with SS3. ss3sim requires an existing SS3 model configuration along with plain-text control files describing alternative population dynamics, fishery properties, sampling scenarios, and assessment approaches. ss3sim then generates an underlying 'truth' from a specified operating model, samples from that truth, modifies and runs an estimation model, and synthesizes the results. The simulations can be run in parallel, reducing runtime, and the source code is free to be modified under an open-source MIT license. ss3sim is designed to explore structural differences between the underlying truth and assumptions of an estimation model, or between multiple estimation model configurations. For example, ss3sim can be used to answer questions about model misspecification, retrospective patterns, and the relative importance of different types of fisheries data. We demonstrate the software with an example, discuss how ss3sim complements other simulation software, and outline specific research questions that ss3sim could address.

description: Die Mortalität des akuten Lungenversagens ist auch nach vielen Dekaden experimenteller und klinischer Forschung weiterhin hoch. Die Beatmungsassoziierte Lungenschädigung (VILI; ventilator-induced lung injury) ist ein integraler Bestandteil des ARDS mit relevanten Einfluss auf Morbidität und Mortalität. Sowohl die Mechanismen des ARDS als auch des VILI sind mittlerweile sehr gut charakterisiert und die bekannten molekularen Mechanismen legen nahe, dass pharmakologische adjuvante Therapien im ARDS/VILI wirksam sein können. In dieser Arbeit wurden exemplarisch drei pharmakologische Therapiestrategien für das akute Lungenversagen untersucht in komplexen Tiermodellen vorgestellt von denen zwei in diesem Kontext effektiv waren: Adrenomedullin und die Neutralisation von C5a. Sowohl Adrenomedullin, als auch die C5a Neutralisation werden derzeit in klinischen Studien bei ARDS und Sepsis untersucht. Neben adjuvanten pharmakologischen Interventionen könnten auch subtile Veränderungen von Beatmungsparametern Einfluss auf den Krankheitsverlauf von ARDS Patient:innen haben. Hier wurde diesbezüglich eine Arbeit vorgestellt, in der die Verlängerung der Inspirationszeit bei gleicher Atemfrequenz, Plateaudrücken, PEEP und Tidalvolumen zur Aggravierung von VILI führt. In der Zukunft könnten sowohl adjuvante pharmakologische Therapien als auch ein besseres Verständnis der Mechanismen von VILI dazu beitragen, das Überleben von Patienten im ARDS zu verbessern.

description: Presented at EuroScienceGateway kickoff 2022-10-06. This work package adds sufficient measures to EuroScienceGateway to support FAIR practices for and by workflows. FAIR Digital Objects (FDOs), for exchanging, publishing, archiving and citing workflows and their companion data, provenance logs and associated resources, will be realized as RO-Crates. The FDOs will be published through EOSC and in EOSC catalogues (e.g. OpenAIRE) and further communicated through outreach plans to increase uptake of the EuroScienceGateway in affiliated and newly targeted computational researcher communities. WorkflowHub, a FAIR registry for workflows that is RO-Crate compliant, will be lifted to TRL-9 status (from TRL-7) and made the registry of choice for all workflow system types and for all disciplines in EOSC. By collaborating with the project CSA INFRA-01-EOSC-01-05 (Enabling discovery and interoperability of federated research objects across scientific communities), both the WorkflowHub and Workflow Digital Objects will be further aligned with the PID and metadata schema frameworks. WP2 Objectives O2.1 Bringing FAIR workflows into EOSC through the EuroScienceGateway O2.2 Support reusable and reproducible workflows O2.3 Establish FAIR Digital Objects as citable exchange format for workflows for all EOSC services O2.4 Establish FAIR Workflow Digital Objects as publishable scholarly objects

description: The entanglement of the spin and orbital degrees of freedom through the spin-orbit coupling has been actively studied in condensed matter physics. In several iridium-oxide systems, the spin-orbital entangled state, identified by the effective angular momentum $j_{\rm eff}$, can host novel quantum phases with the help of electron correlations. Here, we show that a series of lacunar spinel compounds, Ga$M_4X_8$ ($M$ = Nb, Mo, Ta, and W and $X$ = S, Se, and Te), gives rise to a $\textit{molecular}$ $j_{\rm eff}$ state as a new spin-orbital composite on which the low energy effective Hamiltonian is based. A wide range of electron correlations is accessible by tuning the bandwidth under external and/or chemical pressure, enabling us to investigate the interesting cooperation between spin-orbit coupling and electron correlations. As illustrative examples, a two-dimensional topological insulating phase and an anisotropic spin Hamiltonian are investigated in the weak and strong coupling regimes, respectively. Our finding can provide an ideal platform for exploring $j_{\rm eff}$ physics and the resulting emergent phenomena.

Using the path-integral formalism, we compute in-medium splittings allowing transverse motion of all particles in the emission process, thus relaxing the assumption that only the softest particle is permitted such movement. This work constitutes the extension of the computation carried out for x$\rightarrow$1 in Phys. Lett. B718 (2012) 160-168, to all values of x, the momentum fraction of the energy of the parent parton carried by the emitted gluon. In order to accomplish a general description of the whole in-medium showering process, in this work we allow for arbitrary formation times for the emitted gluon. We provide general expressions and their realisation in the path integral formalism within the harmonic oscillator approximation.

description: We study a dissipative Bose-Hubbard chain subject to an engineered bath using a superoperator approach based on matrix product operators. The dissipation is engineered to stabilize a BEC condensate wave function in its steady state. We then characterize the steady state emerging from the interplay between incompatible Hamiltonian and dissipative dynamics. While it is expected that interactions lead to this competition, even the kinetic energy in an open boundary condition setup competes with the dissipation, leading to a non-trivial steady state. We also present results for the transient dynamics and probe the relaxation time revealing the closing of the dissipative gap in the thermodynamic limit.

description: In a randomized controlled trial, we investigated the effects of karate versus a mindfulness-based stress reduction (MBSR) intervention on well-being and cognitive functioning in older adults. Fifty-five adults (52-81 years old) participated in twice-weekly karate versus MBSR sessions or no training for 8 weeks. In pre- and postassessments, subjective well-being, health, cognitive functioning, and chronic stress were measured. Preassessment hair cortisol served as physiological stress marker. The results showed an improvement for the karate group, but not the MBSR and control group, in subjective mental health and anxiety as well as cognitive processing speed. The MBSR group showed by trend as a decrease in stress. No significant correlation between preassessment hair cortisol and postassessment outcomes could be established. But the higher the level of baseline self-reported perceived stress, the higher the increase in depression, anxiety, and chronic stress. Generally, it can be assumed that karate and MBSR showed only small training effects concerning the assessed emotional and cognitive parameters.

description: An exact and regular solution, describing a couple of charged and spinning black holes, is generated in an external electromagnetic field, via Ernst technique, in Einstein-Maxwell gravity. A wormhole instantonic solution interpolating between the two black holes is constructed to discuss, at the semi-classical level, the quantum process of creation rate, in an external magnetic field, of this charged and spinning black hole pair.

Free idempotent generated semigroups and endomorphism monoids of free $G$-acts

description: The study of the free idempotent generated semigroup $\mathrm{IG}(E)$ over a biordered set $E$ began with the seminal work of Nambooripad in the 1970s and has seen a recent revival with a number of new approaches, both geometric and combinatorial. Here we study $\mathrm{IG}(E)$ in the case $E$ is the biordered set of a wreath product $G\wr \mathcal{T}_n$, where $G$ is a group and $\mathcal{T}_n$ is the full transformation monoid on $n$ elements. This wreath product is isomorphic to the endomorphism monoid of the free $G$-act $F_n(G)$ on $n$ generators, and this provides us with a convenient approach. We say that the rank of an element of $F_n(G)$ is the minimal number of (free) generators in its image. Let $\varepsilon=\varepsilon^2\in F_n(G).$ For rather straightforward reasons it is known that if $\mathrm{rank}\,\varepsilon =n-1$ (respectively, $n$), then the maximal subgroup of $\mathrm{IG}(E)$ containing $\varepsilon$ is free (respectively, trivial). We show that if $\mathrm{rank}\,\varepsilon =r$ where $1\leq r\leq n-2$, then the maximal subgroup of $\mathrm{IG}(E)$ containing $\varepsilon$ is isomorphic to that in $F_n(G)$ and hence to $G\wr \mathcal{S}_r$, where $\mathcal{S}_r$ is the symmetric group on $r$ elements. We have previously shown this result in the case $ r=1$; however, for higher rank, a more sophisticated approach is needed. Our current proof subsumes the case $r=1$ and thus provides another approach to showing that any group occurs as the maximal subgroup of some $\mathrm{IG}(E)$. On the other hand, varying $r$ again and taking $G$ to be trivial, we obtain an alternative proof of the recent result of Gray and Ruškuc for the biordered set of idempotents of $\mathcal{T}_n.$

description: Background and objectives: We aimed to determine the risk of complications during cutaneous surgery for the perioperative discontinuation in comparison to the continuation of antithrombotic agents and the bridging of vitamin K antagonists with heparin in comparison to their continuation. Methods: We conducted a systematic review, searching three databases for eligible studies. Methods followed the Cochrane Handbook. We used RoB 2 and ROBINS-I to assess risk of bias. The quality of evidence was judged (GRADE). Fixed-effect meta-analyses were performed. Results: Two randomized-controlled trials and 19 prospective cohort studies were included. It is uncertain whether, compared to its discontinuation, continuing acetylsalicylic acid (risk difference (RD) 0.004, 95 % confidence interval (CI) -0.003 to 0.019) perioperatively increases the risk of significant postoperative bleedings (SPB). Compared to its discontinuation, continuing phenprocoumon perioperatively may increase the risk of SPB (RD 0.02, 95 % CI 0.00 to 0.05). Bridging phenprocoumon with heparin perioperatively may increase the risk of SPB when compared to its continuation (RD 0.07, 95 % CI 0.01 to 0.22). No evidence was found regarding bleeding risks for direct oral anticoagulants. Conclusions: No clear indications of major risks of bleedings when continuing antithrombotic agents during minor skin surgeries were identified. However, the quality of evidence was very low.
Universal fluctuation-driven eccentricities in proton-proton, proton-nucleus and nucleus-nucleus collisions

description: We show that the statistics of fluctuation-driven initial-state anisotropies in proton-proton, proton-nucleus and nucleus-nucleus collisions is to a large extent universal. We propose a simple parametrization for the probability distribution of the Fourier coefficient $\varepsilon_n$ in harmonic $n$, which is in good agreement with Monte-Carlo simulations. Our results provide a simple explanation for the 4-particle cumulant of triangular flow measured in Pb-Pb collisions, and for the 4-particle cumulant of elliptic flow recently measured in p-Pb collisions. Both arise as natural consequences of the condition that initial anisotropies are bounded by unity. We argue that the initial rms anisotropy in harmonic $n$ can be directly extracted from the measured ratio $v_n\{4\}/v_n\{2\}$: this gives direct access to a property of the initial density profile from experimental data. We also make quantitative predictions for the small lifting of degeneracy between $v_n\{4\}$, $v_n\{6\}$ and $v_n\{8\}$. If confirmed by future experiments, they will support the picture that long-range correlations observed in p-Pb collisions at the LHC originate from collective flow proportional to the initial anisotropy.

description: Chronic pruritus is a common and debilitating symptom in patients with atopic dermatitis and contributes to impairment of quality of life. Effective treatment of pruritus should therefore be one of the main treatment goals in patients with atopic dermatitis. Pathophysiologically, the histamine-independent pruritogens interleukin-31, interleukin-13, and interleukin-4, have been shown to play a major role in atopic dermatitis. All three cytokines can mediate chronic pruritus via Janus kinase 1/2 signaling pathways. Novel drugs target these pathways and have shown rapid and sustained reduction of pruritus in patients with atopic dermatitis in clinical use and in phase II and III clinical trials. Here we summarize the published data on the effects of these drugs on itch parameters such as overall reduction in pruritus intensity and percent of patients with atopic dermatitis achieving a relevant reduction in itch. Each of the novel drugs shows very good effects on pruritus. These data offer hope for an even better and possibly more specific treatment of pruritus in patients with atopic dermatitis in the future. In addition, the different pharmacological approaches give us the chance to learn more about the pathophysiology of pruritus in atopic dermatitis.
