description: The successful fabrication of one monolayer FeSe on SrTiO$_{3}$ represented a real breakthrough in searching for high-T$_{c}$ Fe-based superconductors (Ref. 1). Motivated by this important discovery, we studied the effects of tensile strain on one monolayer and bulk iron-chalcogenide superconductors (FeSe and FeTe), showing that it produces important magnetic and electronic changes in the systems. We found that the magnetic ground state of bulk and monolayer FeSe is the block-checkerboard phase, which turns into the collinear stripe phase under in plane tensile strain. FeTe, in both bulk and monolayer phases, shows two magnetic transitions upon increasing the tensile strain: from bicollinear in the ground state to block-checkerboard ending up to the collinear antiferromagnetic phase which could bring it in the superconducting state. Finally, the study of the mechanical properties of both FeSe and FeTe monolayers reveals their enormous tensile strain limits and opens the possibility to grow them on different substrates.

description: One goal of assistive robotics is to design interactive robots that can help disabled people with tasks such as fetching objects. When people do this task, they coordinate their movements closely with receivers. We investigated how a robot should fetch and give household objects to a person. To develop a model for the robot, we first studied trained dogs and person-to-person handoffs. Our findings suggest two models of handoff that differ in their predictability and adaptivity.

description: We study in-gap electronic states induced by a nonmagnetic defect with short-range potential in two-dimensional topological insulators and trace their evolution as the distance between the defect and the boundary changes. The defect located far from the boundary is found to produce two bound states independently of the sign of its potential. The states are classified as electronlike and holelike. Each of these states can have two types of the spatial distribution of the electron density. The first-type states have a maximum of the density in the center and the second-type ones have a minimum. When the defect is coupled with the boundary, the bound states are transformed correspondingly into resonances of two types and take up the form of the edge states flowing around the defect. Under certain conditions, two resonances interfere giving rise to the formation of a bound state embedded into the continuum spectrum of the edge states flowing around the defect. We calculate the spatial distribution of the electron density in the edge states flowing around the defect and estimate the charge accumulated near the defect. The current density field of the edge states flowing around the defect contains two components one of which flows around the defect and the other circulates around it.

description: Hybrid system must perform not only services from the owner point of view, but it must be designed to provide also energy services to external requests (DSO), following the paradigm of “Energy as a Service” (EaaS). Therefore, particular attention must be paid to the requirements for the interoperability considering both power and energy capabilities associated to each one of the components or subsystems involved in the overall HESS (hybrid energy storage system). In the proposed hybrid configuration, the high-power efficiency and fast response battery, here based on a lithium ion battery, launch and facilitate the use of the large energy capacity battery, here based on AORFB, allowing this last battery, energy buffer, to work in the maximum efficiency working points making profitable the investment made in this hybrid system and making it more sustainable. Under these conditions, AORFB battery component extends the storage capacity of the lithium ion battery component, resulting in a final system able to cover a great part of the requirements that an ESS might have, saving investment and wining performances. The integration of both component systems must be carried out by choosing the right power electronics architecture with fast response based on the power buffer battery and energy management capability. Only active HESS topologies are considered here, which consist of two or more separate power converters for battery management. Although the complexity, losses, and cost of the system increase, this kind of architectures gives the possibility to actively control both energy storage component systems combining power and energy capabilities.
ADDRESSING MENSTRUAL STIGMA: THE CASE FOR IMPLEMENTING MENSTRUAL LEAVE AS A LEGAL PROVISION IN INDIA

description: This paper explores the need for a legal provision for menstrual leave in India to address the stigma surrounding menstruation and promote gender equality in the workplace and society. Menstrual leave refers to a policy that allows women to take time off from work or school during their menstrual cycles. While some companies in India have voluntarily introduced menstrual leave policies, there is no legal provision for it yet. The paper argues that a legal provision for menstrual leave is necessary to ensure that women are not discriminated against in the workplace and have the right to take time off during their menstrual cycles. However, the paper also acknowledges concerns about the implementation of menstrual leave policies and suggests that the policy should be carefully crafted, with proper guidelines for its implementation, to address concerns about its misuse and promote gender neutrality. Ultimately, the paper concludes that implementing a legal provision for menstrual leave in India is crucial for addressing menstrual stigma and promoting gender equality in the workplace and society.
title: Creating stimulating environments for young people in residential care : the Israeli youth village 'ecological' model
Creators: name: Grupper, Emmanuel
Publisher: name: Strathprints - University of Strathclyde
Year: 2005

description: In many industrialised countries, the use of residential education and care for children and youth at risk has decreased over recent years (Knorth & Van de Ploeg, 1994). There are many reasons for this, however, some are certainly related to the negative stigma attached today to any kind of institutionalised setting. Such programmes are now considered in many European countries as a last resort used only when all other interventions have failed. In addition, the ever-increasing cost of treating a child in a residential care therapeutic programme is encouraging policy makers to look for less expensive solutions, even though their effectiveness has not always been proven (Grupper, 2002).

description: Exact calculations are performed on the two-dimensional strongly interacting, unpolarized, uniform Fermi gas with a zero-range attractive interaction. Two auxiliary-field approaches are employed which accelerate the sampling of imaginary-time paths using BCS trial wave functions and a force bias technique. Their combination enables calculations on large enough lattices to reliably compute ground-state properties in the thermodynamic limit. A new equation of state is obtained, with a parametrization provided, which can serve as a benchmark and allow accurate comparisons with experiments. The pressure, contact parameter, and condensate fraction are determined systematically vs.~$k_F a$. The momentum distribution, pairing correlation, and the structure of the pair wave function are computed. The use of force bias to accelerate the Metropolis sampling of auxiliary-fields in determinantal approaches is discussed.

description: Low-cost navigation solutions for indoor environments have a variety of real-world applications ranging from emergency evacuation to mobility aids for people with disabilities. Challenges for indoor navigation include robust localization in the absence of GPS, intuitive recognition of user navigation goals, and efficient route-planning and re-planning techniques. In this paper, we present an architecture for indoor navigation that integrates observed behavior for recognizing user navigation goals and estimating future paths without direct input from the user. Our architecture comprises of three core components: effective localization, map representation and route planning, and plan recognition. The outlined architecture is unique in its integration of the core navigation and prediction components. To evaluate the feasibility of the proposed architecture, we develop a prototype application on a commercial smart-phone. The developed application was tested in an indoor environment and was found to accurately predict intended destination and to provide effective navigation guidance to the user.

description: This letter discusses phenomenological aspects of dimensional reduction predicted by the Causal Dynamical Triangulations (CDT) approach to quantum gravity. The deformed form of the dispersion relation for the fields defined on the CDT space-time is reconstructed. Using the Fermi satellite observations of the GRB 090510 source we find that the energy scale of the dimensional reduction is $E_* > 0.7 \sqrt{4-d_{\rm UV}} \cdot 10^{10}$ GeV at (95 $\%$ CL), where $d_{\rm UV}$ is the value of the spectral dimension in the UV limit. By applying the deformed dispersion relation to the cosmological perturbations it is shown that, for a scenario when the primordial perturbations are formed in the UV region, the scalar power spectrum $\mathcal{P}_S \propto k^{n_S-1}$ where $n_S-1\approx \frac{3 r (d_{\rm UV}-2)}{(d_{\rm UV}-1)r-48}$. Here, $r$ is the tensor-to-scalar ratio. We find that within the considered model, the predicted from CDT deviation from the scale-invariance ($n_S=1$) is in contradiction with the up to date Planck and BICEP2 data.

Probabilistically Complete Planning with End-Effector Pose Constraints

Year: 2018
Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics

description: We present a proof for the probabilistic completeness of RRT-based algorithms when planning with constraints on end-effector pose. Pose constraints can induce lower-dimensional constraint manifolds in the configuration space of the robot, making rejection sampling techniques infeasible. RRT-based algorithms can overcome this problem by using the sample-project method: sampling coupled with a projection operator to move configuration space samples onto the constraint manifold. Until now it was not known whether the sample-project method produces adequate coverage of the constraint manifold to guarantee probabilistic completeness. The proof presented in this paper guarantees probabilistic completeness for a class of RRT-based algorithms given an appropriate projection operator. This proof is valid for constraint manifolds of any fixed dimensionality.

description: Composite solid propellants can be mixed by a variety of techniques. Recent RD efforts have considered implementation of resonant acoustic mixing (RAM) strategies for improved homogeneity, reduced complexity, and faster mixing capabilities. In the current study, a standard high-performance propellant formulation (85% trimodal AP, 1.3% Fe2O3, 1.0% Al2O3) was mixed by standard laboratory techniques (i.e., hand mixed) and RAM to allow for direct comparison of these methods. Propellant samples were burned in a constant-volume, optically accessible strand burner at pressures between 3.4520.7 MPa (5003,000 psia). Propellant microstructures were evaluated with scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) techniques. Implementation of RAM yielded a significant increase in the propellant burning rate (~25%) in comparison to the standard hand-mixing strategy. The observed performance improvement in the RAM formulation was attributed to improved catalyst/oxidizer contact, yielding improved catalysis during propellant combustion.

description: Halogen compounds are capable of playing an important role in the manipulation of nanoparticle shapes and properties. In a new approach, we examined the shape evolution of CdSe nanorods to hexagonal pyramids in a hot-injection synthesis under the influence of halogenated additives in the form of organic chlorine, bromine and iodine compounds. Supported by DFT calculations, this shape evolution is explained as a result of X-type ligand coordination to sloped and flat Cd-rich facets and an equilibrium shape strongly influenced by halides. Synchrotron XPS measurements and TXRF results show that the shape evolution is accompanied by a modification in the chemical composition of the ligand sphere. Our experimental results suggest that the molecular structure of the halogenated compound is related to the degree of the effect on both rod growth and further shape evolution. This presents a new degree of freedom in nanoparticle shape control and highlights the role of additives in nanoparticle synthesis and their possible in situ formation of ligands.

description: Motion planning in the most general sense is an optimization problem with a single elusive best solution. However attempting to find a single answer isn’t often the most desired approach. On the one hand, the reason is theoretical - planners often get trapped in local minimas because the cost function has many valleys or dynamics are too complex to fully exploit. On the other hand, there are many practical deterrents - unmapped obstacles might require the system to switch quickly to another plan, unmodelled dynamics can make a computed plan infeasible, or the system may have a human-in-loop who has a vote in the decision process. In situations where the current plan is no longer desirable, a new plan has to be planned. The re-planning time induces a reaction latency which might result in mission failure.
We advocate the use of alternate routes (AR), a set of spatially different, locally optimal paths, as a powerful tool to address several of the afore-mentioned issues. By enforcing the routes to be spatially separated, appearance of unexpected obstacles has less chance of rendering all trajectories to be infeasible. In such cases, alternate routes act as a set of backup options which can be switched to instantly.
This reduces reaction latency allowing the system to operate with a lower risk. This paper presents an algorithm, RRT*-AR, to generate alternate routes in real time by making tradeoffs in exploitation for exploration, precision for speed and leveraging assumptions about the vehicle and environment constraints. In the case of emergency landing of a helicopter, RRT*-AR outperformed RRT* by providing the human 280% more flight paths 67% faster on average. By planning multiple routes to potential landing zones, the planner was able to seamlessly switch to a new landing site without having to replan.

description: Antibiotic pollution is an emerging environmental challenge. Residual antibiotics from various sources, including municipal and industrial wastewater, sewage discharges, and agricultural runoff, are continuously released into freshwater environments, turning them into reservoirs that contribute to the development and spread of antibiotic resistance. Thus, it is essential to understand the impacts of antibiotic residues on aquatic organisms, especially microalgae and cyanobacteria, due to their crucial roles as primary producers in the ecosystem. This review summarizes the effects of antibiotics on major biological processes in freshwater microalgae and cyanobacteria, including photosynthesis, oxidative stress, and the metabolism of macromolecules. Their adaptive mechanisms to antibiotics exposure, such as biodegradation, bioadsorption, and bioaccumulation, are also discussed. Moreover, this review highlights the important factors affecting the antibiotic removal pathways by these organisms, which will promote the use of microalgae-based technology for the removal of antibiotics. Finally, we offer some perspectives on the opportunities for further studies and applications.

description: We describe a real-time pedestrian detection system intended for use in automotive applications. Our system demonstrates superior detection performance when compared to many state-of-the-art detectors and is able to run at a speed of 14 fps on an Intel Core i7 computer when applied to 640×480 images. Our approach uses an analysis of geometric constraints to efficiently search feature pyramids and increases detection accuracy by using a multiresolution representation of a pedestrian model to detect small pixel-sized pedestrians normally missed by a single representation approach. We have evaluated our system on the Caltech Pedestrian benchmark which is currently the largest publicly available pedestrian dataset at the time of this publication. Our system shows a detection rate of 61% with 1 false positive per image (FPPI) whereas recent other state-of-the-art detectors show a detection rate of 50% ~ 61% under the `reasonable' test scenario (explained later). Furthermore, we also demonstrate the practicality of our system by conducting a series of use case experiments on selected videos of Caltech dataset.

description: We present a study of the central exclusive $π^{+} π^{-}$ production via the photoproduction mechanism in nucleon-nucleon collisions. The photon-pomeron/reggeon and pomeron/reggeon-photon exchanges both for the $ρ^{0}$ resonance contribution and the Drell-Söding contribution are considered. The amplitudes for the processes are formulated in terms of vertices respecting the standard crossing and charge-conjugation relations of Quantum Field Theory. The coupling parameters of tensor pomeron and reggeon exchanges are fixed based on the H1 and ZEUS experimental data for the $γp \to ρ^{0} p$ reaction. We present first predictions of this mechanism for the $pp \to pp π^{+} π^{-}$ reaction being studied at COMPASS, RHIC, Tevatron, and LHC. We show the influence of the experimental cuts on the integrated cross section and on various differential distributions for outgoing particles. Distributions in rapidities and transverse momenta of outgoing protons and pions as well as correlations in azimuthal angle between them are presented. We compare the photoproduction contribution to $π^{+} π^{-}$ distributions with double pomeron/reggeon two-pion continuum. We discuss whether the high-energy central production of $ρ^{0}$ mesons could be selected experimentally.

algorithms (detection, classification, and correspondence) and mission planning. In detection, we have achieved improved
rejection of camera jitter and environmental variations (e.g., lighting, moving foliage) through multi-modal filtering, and we
have implemented panoramic backgrounding through pseudo-real-time mosaicing. In classification, we present methods for
discriminating between individuals, groups of individuals, and vehicles, and between individuals with and without
backpacks. In correspondence, we describe an accurate multi-hypothesis approach based on both motion and appearance.
Finally, in mission planning, we describe mapbuilding using multiple sensory cues and a computationally efficient
decentralized planner for multiple platforms.

description: Registering a surgical tool to an a priori model of the environment is an important first step in computer-aided robotic surgery. Registration of the surgical tool to a flexible environment such as an organ is difficult due to organ shifting and deformation. Palpating an organ reveals stiffness information that can serve as anatomic fiducials and facilitate the registration. In this work, locally stiff features such as arteries and tumors are used to preregister the tool to the organ model. Following that, we use a Kalman filtering framework to register the surgical tool to the surface of the organ. The tissue is palpated with regulated forces and a palpation depth dependent stiffness model is used to capture the interaction between the tool and the tissue. We believe this is the first presentation of a method to preregister and register a surgical tool to a flexible environment using only mechanical palpation. The algorithm is experimentally evaluated using a 3-DOF Cartesian slave robot that interacts with a phantom tissue model. The effectiveness of the preregistration step and the registration algorithm are validated and the results demonstrate that the proposed method improves registration accuracy and the preregistration step leads to faster convergence

description: The immune system of teleosts offers many ideas to deepen the immune mechanisms and cells in general. The use of zebrafish as an experimental model is increased in recent years, thanks to its genetic and anatomical characteristics. It is known that several natural compounds exert an action on the immune system, boosting it. Spirulina, a non-toxic blue-green alga, has been declared a superfood for its peculiar biological activities. In this study, we test the immunostimulant effect of spirulina on zebrafish liver macrophages by immunohistochemical analysis using optical and confocal microscopy. Our results have shown an increase in the number of macrophages after feeding with spirulina, furthermore, this natural ‘superfood’ can induce macrophages aggregation. These data not only provide information on the possible effect of this alga as a complementary feed on the immune cells of teleost, but also improve the knowledge of the immune mechanisms of vertebrates.

description: Flavonoids are polyphenolic natural compounds with various biological actions and limited toxicity including diosmin (DM) which is considered a safe flavonoid natural type with anti-inflammatory and antioxidant activities. Tramadol (TM) is a centrally long-acting analgesic class of opioids extensively being used among the population. It was reported that long-term exposure to TM triggers the releases of oxidative stress, inflammatory factors, and nitric oxides resulting in organs damage. This study aimed to investigate the possible ameliorative and restorative actions of DM against tramadol-induced testicular damage. Rats were divided into: GI: control; GII: Rats received TM, GIII: Rats received DM, GIV: Rats received TM + DM; GV: Rats received DM + TM. Rat's testicular tissue and blood samples were collected. A relevant improvement in all examined parameters was observed among GIV and GV groups. Thereby, it was highlighted that diosmin has beneficial natural actions against tramadol-induced testicular injury via suppressing triggered oxidative stress, and inflammatory factors.

description: The rate at which interstellar gas is converted into stars, and its dependence on environment, is one of the pillars on which our understanding of the visible Universe is build. We present a comparison of the surface density of young stars (Sigma_*) and dust surface density (Sigma_d) across NGC346 (N66) in 115 independent pixels of 6x6 pc^2. We find a correlation between Sigma_* and Sigma_d with a considerable scatter. A power law fit to the data yields a steep relation with an exponent of 2.6+-0.2. We convert Sigma_d to gas surface density (Sigma_g) and Sigma_* to star formation rate (SFR) surface densities (Sigma_SFR), using simple assumptions for the gas-to-dust mass ratio and the duration of star formation. The derived total SFR (4+-1 10^-3 M_sun/yr) is consistent with SFR estimated from the Ha emission integrated over the Ha nebula. On small scales the Sigma_SFR derived using Ha systematically underestimates the count-based Sigma_SFR, by up to a factor of 10. This is due to ionizing photons escaping the area, where the stars are counted. We find that individual 36 pc^2 pixels fall systematically above integrated disc-galaxies in the Schmidt-Kennicutt diagram by on average a factor of ~7. The NGC346 average SFR over a larger area (90 pc radius) lies closer to the relation but remains high by a factor of ~3. The fraction of the total mass (gas plus young stars) locked in young stars is systematically high (~10 per cent) within the central 15 pc and systematically lower outside (2 per cent), which we interpret as variations in star formation efficiency. The inner 15 pc is dominated by young stars belonging to a centrally condensed cluster, while the outer parts are dominated by a dispersed population. Therefore, the observed trend could reflect a change of star formation efficiency between clustered and non-clustered star-formation.

description: The dynamical transverse magnetic Kohn-Sham susceptibility calculated within time-dependent density functional theory shows a fairly linear behavior for a finite energy window. This observation is used to propose a scheme where the computation of this quantity is greatly simplified. Regular simulations based on static density functional theory can be used to extract the dynamical behavior of the magnetic response function. Besides the ability to calculate elegantly damping of magnetic excitations, we derive along the way useful equations giving the main characteristics of these excitations: effective $g$-factors and the resonance frequencies that can be accessed experimentally using inelastic scanning tunneling spectroscopy or spin-polarized electron energy loss spectroscopy.

description: Integration is a reality of the contemporary world. The concept 'integration' is defined as 'a process where different elements are combined together in one community, while each of these elements preserves its own basic identity' (Pabriks, Vēbers, Āboliņš, 2001, p.6). Social integration is seen as crucial to the development of the Latvian state, because such integration should encourage everyone in society to take a tolerant, considerate and understanding view of other people. It appeals to the person to become a creator of subjective relationships and not to be indifferent to the plight of others who may be less fortunate. In short, social integration is seen as a key to the promotion of children's rights.

description: We report a new limit on a possible short range spin-dependent interaction from the precise measurement of the ratio of Larmor precession frequencies of stored ultracold neutrons and $^{199}$Hg atoms confined in the same volume. The measurement was performed in a $\sim$1$μ$ T vertical magnetic holding field with the apparatus searching for a permanent electric dipole moment of the neutron at the Paul Scherrer Institute. A possible coupling between freely precessing polarized neutron spins and unpolarized nucleons of the wall material can be investigated by searching for a tiny change of the precession frequencies of neutron and mercury spins. Such a frequency change can be interpreted as a consequence of a short range spin-dependent interaction that could possibly be mediated by axions or axion-like particles. The interaction strength is proportional to the CP violating product of scalar and pseudoscalar coupling constants $g_Sg_P$. Our result confirms limits from complementary experiments with spin-polarized nuclei in a model-independent way. Limits from other neutron experiments are improved by up to two orders of magnitude in the interaction range of $10^{-6}

WIND TUNNEL
MEASUREMENT TECHNIQUE

description: The relevance of wind tunnel experiments significantly depends on the quality of the free-stream flow and on the accuracy with which it is characterized. Significant challenges arise in hypersonic tunnels. These facilities indeed often exhibit dense gas effects, high-temperatures, non-equilibrium effects, and may be limited to short test times. Major improvements have been achieved over the past decade within the VKI Longshot hypersonic tunnel thanks to the introduction of novel probes aimed at direct free-stream static pressure measurements. This resulted in improved accuracy on the reference free-stream flow quantities, further supported by independent non-intrusive diagnostic techniques [1]. Yet, the set of quantities characterizing the free-stream deviates from former theoretical and numerical simulations of the nozzle flow expansion for reasons that remain to be identified. In the present study, we endeavor to narrow down the possible origin of the physical phenomenon that leads to the discrepancies reported earlier by modeling the flow expansion through the axisymmetric contoured nozzle of the Longshot wind tunnel. To this end, we rely on the US3D flow solver [2] and systematically investigate the influence of different physical models (dense gas effects, high-temperature, thermal non-equilibrium, and turbulence) onto the nozzle flow expansion using a steady state RANS approach. The solver allows to assess the influence of: I) dense gas effects by adding the molecular volume correction of the van der Waals equation to the ideal gas equation of state, II) high-temperature effects that lead to non-calorically perfect behavior, III) thermal non-equilibrium effects, which arise because of the rapid expansion, by using a two temperature model, IV) different turbulence models. The influence of the nozzle wall temperature on the flow expansion is evaluated next. Former computations have all assumed an isothermal nozzle wall temperature, although significant temperature changes are expected around the nozzle throat. The influence of a heated nozzle throat on the rest of the flow expansion is therefore also investigated. For each set of numerical results, comparisons against reference experimental data (free-stream flow quantities, radial flow profiles, and measurements along the nozzle wall) will be reported. This will lead to the identification of the physical models that yield the best modelling of the nozzle flow. Recommendations for further betterment of the modelling will be issued based on the present findings.

description: Corn silk (Stigma maydis), being the styles and stigmas of maize, is a famous traditional medicine and functional tea in China. Research into the chemical composition of corn silk led to the identification of an unreported flavone (1, silkone A), accompanying with three known flavonoids (2–4). And their structures were elucidated through comprehensive spectroscopic analysis. Each obtained compound was evaluated for antioxidant capacity by DPPH, ABTS and FRAP assays. As a result, all tested compounds exhibited stronger radicals scavenging activities than Trolox in ABTS radical assay and displayed relatively weak antioxidant capacity in the other two experiments. Tyrosinase inhibitory activities of compounds 1–4 were also investigated, and compounds 3 and 4 demonstrated moderate inhibitory activities to tyrosinase with IC50 values of 0.49 and 0.21 mM, respectively, which was further investigated through molecular docking calculation. These results may contribute to the development of novel antioxidants and tyrosinase inhibitors from corn silk.

description: Azimuthal correlations in $\mathrm {Z} +$jet production at large transverse momenta are computed by matching Parton-Branching (PB) TMD parton distributions and showers with NLO calculations via MCatNLO. The predictions are compared with those for dijet production in the same kinematic range. The azimuthal correlations $\Delta \phi $ between the Z boson and the leading jet are steeper compared to those in dijet production at transverse momenta $\mathcal{O}(100)$ GeV , while they become similar for very high transverse momenta ${{\mathcal {O}}}(1000)$ GeV . The different patterns of $\mathrm {Z} +$jet and dijet azimuthal correlations can be used to search for potential factorization-breaking effects in the back-to-back region, which depend on the different color and spin structure of the final states and their interferences with the initial states. In order to investigate these effects experimentally, we propose to measure the ratio of the distributions in $\Delta \phi $ for $\mathrm {Z} +$jet- and multijet production at low and at high transverse momenta, and compare the results to predictions obtained assuming factorization. We examine the role of theoretical uncertainties by performing variations of the factorization scale, renormalization scale and matching scale. In particular, we present a comparative study of matching scale uncertainties in the cases of PB-TMD and collinear parton showers.
