description: Theoretical and experimental studies have shown that the fluctuations of in vivo systems break the fluctuation-dissipation theorem. One can thus ask what information is contained in the correlation functions of protein concentrations and how they relate to the response of the reactive network to a perturbation. Answers to these questions are of prime importance to extract meaningful parameters from the in vivo fluorescence correlation spectroscopy data. In this paper we study the fluctuations of the concentration of a reactive species involved in a cyclic network that is in a non-equilibrium steady state perturbed by a noisy force, taking into account both the breaking of detailed balance and extrinsic noises. Using a generic model for the network and the extrinsic noise, we derive a Chemical Langevin Equation that describes the dynamics of the system, we determine the expressions of the correlation functions of the concentrations, estimate the deviation of the fluctuation-dissipation theorem and the range of parameters in which an effective temperature can be defined.

description: Metal-induced histidine deprotonation may have tremendous effects on metalloprotein catalysis. Here, we explore protonation states of all active site histidines in superoxide reductase (SOR), a non-heme iron enzyme catalysing the reduction of superoxide to hydrogen peroxide. Using experimental and theoretical techniques, we show that these amino acids remain in their neutral state under physiological conditions, excluding deprotonation. Based on our findings, alternative explanations for lack of H/D exchange of SOR histidines are discussed, including high barriers for acid/base reactions of coordinated ligands.

Transient dynamics of perturbations in astrophysical disks

description: This paper reviews some aspects of one of the major unsolved problems in understanding astrophysical (in particular, accretion) disks: whether the disk interiors may be effectively viscous in spite of the absence of marnetorotational instability? In this case a rotational homogeneous inviscid flow with a Keplerian angular velocity profile is spectrally stable, making the transient growth of perturbations a candidate mechanism for energy transfer from the regular motion to perturbations. Transient perturbations differ qualitatively from perturbation modes and can grow substantially in shear flows due to the nonnormality of their dynamical evolution operator. Since the eigenvectors of this operator, alias perturbation modes, are mutually nonorthogonal, they can mutually interfere, resulting in the transient growth of their linear combinations. Physically, a growing transient perturbation is a leading spiral whose branches are shrunk as a result of the differential rotation of the flow. This paper discusses in detail the transient growth of vortex shear harmonics in the spatially local limit as well as methods for identifying the optimal (fastest growth) perturbations. Special attention is given to obtaining such solutions variationally, by integrating the direct and adjoint equations forward and backward in time, respectively. The material is presented in a newcomer-friendly style.

With help of the Astrophysics Data System (NASA/ADS), I trace the growth of the research community over the past century from a few dozen researchers early in the 20-th Century to over 4,000 names with over refereed 2,000 publications in recent years, with 90% originating from 20 countries, being published in 90 distinct journals. Overall, the lead authors of these publications have their affiliations for 45% in Europe, 29% in the Americas, 24% in Australasia, and 2% in Africa and Arab countries. Publications most frequently appear (in decreasing order) in the Astrophysical Journal, the Journal of Geophysical Research (Space Physics), Solar Physics, Astronomy and Astrophysics, and Advances in Space Research (adding up to 59% of all publications in 2015).

title: Say what you pay? Pay Information Disclosure in German Job Postings
Creators: name: Vormann, Claus
Publisher: name: Fachhochschule Dortmund
Year: 2023
Subjects: subject: 330 Wirtschaft

description: Purpose – Pay transparency is a promising topic both for research and practice. In particular, the new European directive on compensation transparency will increase its importance. However, research is still relatively sparse compared to other areas of HRM. In particular, state-of-the-art and use of pay information disclosure in job postings is neglected. This paper aims to shed light on this HRM topic. Methodology – The paper summarizes the findings of a preliminary study conducted among German companies researching the proportion of firms offering compensation information in job postings and digging into the reasons behind it. Findings – Only 17 % of the participating companies disclose meaningful information about compensation in their job postings. Doing so mainly depends on the company’s attitude towards pay transparency. The age of the company has a minor negative influence, i.e.~older companies are less prone to disclose salary information. Industry, size, and existing overall pay transparency in the company do not determine if pay information is disclosed in job postings. Research limitations – The main limitation of this survey is its small size of 88 participants and the snowball sampling approach employed. This limits its representativeness and calls for follow-up studies involving more companies and a wider variation of positions included. Practical implications – While the EU directive will make it obligatory to communicate about pay before the first interview, some companies do it already. The study helps HR departments that think about changing their practice before it becomes compulsory to better judge the current standards.
Occam's Razor in Quark Mass Matrices

description: On the standpoint of Occam's Razor approach, we consider the minimum number of parameters in the quark mass matrices needed for the successful CKM mixing and CP violation. We impose three zeros in the down-quark mass matrix with taking the diagonal up-quark mass matrix to reduce the number of free parameters. The three zeros are maximal zeros in order to have a CP violating phase in the quark mass matrix. Then, there remain six real parameters and one CP violating phase, which is the minimal number to reproduce the observed data of the down-quark masses and the CKM parameters. The twenty textures with three zeros are examined. Among them, the thirteen textures are viable for the down-quark mass matrix. As a representative of these textures, we discuss a texture $M_d^{(1)}$ in details. By using the experimental data on $\sin 2β$, $θ_{13}$ and $θ_{23}$ together with the observed quark masses, the Cabibbo angle is predicted to be close to the experimental data. It is found that this surprising result remains unchanged in all other viable textures. We also investigate the correlations among $|V_{ub}/V_{cb}|$, $\sin 2β$ and $J_{CP}$. For all textures, the maximal value of the ratio $|V_{ub}/V_{cb}|$ is $0.09$, which is smaller than the upper-bound of the experimental data, $0.094$. We hope that this prediction will be tested in future experiments.

As an application, a Poisson generalized Weyl algebra $A_1$ considered as a Poisson version of the quantum generalized Weyl algebra is constructed and its Poisson structures are studied. In particular, it is obtained a necessary and sufficient condition such that $A_1$ is Poisson simple and established that the Poisson endomorphisms of $A_1$ are Poisson analogues of the endomorphisms of the quantum generalized Weyl algebra.

description: The synthesis and texturization processes of fluorinated surfaces by means of atmospheric plasma are investigated and presented through an integrated study of both the plasma phase and the resulting material surface. Three methods enhancing the surface hydrophobicity up to the production of super-hydrophobic surfaces are evaluated: (i) the modification of a polytetrafluoroethylene (PTFE) surface, (ii) the plasma deposition of fluorinated coatings and (iii) the incorporation of nanoparticles into those fluorinated films. In all the approaches, the nature of the plasma gas appears to be a crucial parameter for the desired property. Although a higher etching of the PTFE surface can be obtained with a pure helium plasma, the texturization can only be created if O2 is added to the plasma, which simultaneously decreases the total etching. The deposition of CxFy films by a dielectric barrier discharge leads to hydrophobic coatings with water contact angles (WCAs) of 115{\textdegree}, but only the filamentary argon discharge induces higher WCAs. Finally, nanoparticles were deposited under the fluorinated layer to increase the surface roughness and therefore produce super-hydrophobic hybrid coatings characterized by the nonadherence of the water droplet at the surface.

Minutieux et généreux dans ses analyses, le philosophe de l’UCLouvain sollicite tous les écrits philosophiques, ainsi que leur littérature auxiliaire, qui problématisent ouvertement ou sporadiquement la solitude. Dès le départ, la solitude ne va pas sans deux points d’intérêt : d’une part, pour être seul, il faut d’abord être, c’est-à-dire être en première personne ; d’autre part, cette solitude est jugée, tantôt bonne, tantôt mauvaise, tantôt bénéfique, tantôt désastreuse. Cette distinction fondamentale montre qu’il est question des solitudes.
Spin crossover in (Mg,Fe$^{3+}$)(Si,Fe$^{3+}$)O$_3$ bridgmanite: effects of disorder, iron concentration, and temperature

description: The spin crossover of iron in Fe$^{3+}$-bearing bridgmanite, the most abundant mineral of the Earth's lower mantle, is by now a well-established phenomenon, though several aspects of this crossover remain unclear. Here we investigate effects of disorder, iron concentration, and temperature on this crossover using ab initio LDA + U$_{sc}$ calculations. The effect of concentration and disorder are addressed using complete statistical samplings of coupled substituted configurations in super-cells containing up to 80 atoms. Vibrational/thermal effects on the crossover are addressed within the quasiharmonic approximation. The effect of disorder seems quite small, while increasing iron concentration results in considerable increase in crossover pressure. Our calculated compression curves for iron-free, Fe$^{2+}$-, and Fe$^{3+}$-bearing bridgmanite compare well with the latest experimental measurements. The comparison also suggests that in a close system, Fe$^{2+}$ present in the sample may transform into Fe$^{3+}$ by introduction of Mg and O vacancies with increasing pressure. As in the spin crossover in ferropericlase, this crossover in bridgmanite is accompanied by a clear volume reduction and an anomalous softening of the bulk modulus throughout the crossover pressure range. These effects reduce significantly with increasing temperature. Though the concentration of [Fe$^{3+}$]$_{Si}$ in bridgmanite may be small, related elastic anomalies may impact the interpretation of radial and lateral velocity structures of the Earth's lower mantle.

description: To optimize the adhesion of layers presenting strong barrier properties on low-density polyethylene (LDPE) surfaces, we investigated the influence of argon and argon-oxygen atmospheric pressure post-discharges. This study was performed using x-ray photoelectron spectroscopy, atomic force microscopy, optical emission spectroscopy (OES) and dynamic water contact angle (WCA) measurements. After the plasma treatment, a slight increase in the roughness was emphasized, more particularly for the samples treated in a post-discharge supplied in oxygen. Measurements of the surface roughness and of the oxygen surface concentration suggested the competition of two processes playing a role on the surface hydrophilicity and occurring during the post-discharge treatment: the etching and the activation of the surface. The etching rate was estimated to about 2.7 nm.s-1 and 5.8 nm.s-1 for Ar and Ar-O2 post-discharges, respectively. The mechanisms underlying this etching were investigated through experiments, in which we discuss the influence of the O2 flow rate and the distance (gap) separating the plasma torch from the LDPE surface located downstream. O atoms and NO molecules (emitting in the UV range) detected by OES seem to be good candidates to explain the etching process. An ageing study is also presented to evidence the stability of the treated surfaces over 60 days. After 60 days of storage, we showed that whatever the O2 flow rate, the treated films registered a loss of their hydrophilic state since their WCA increased towards a common threshold of 80{\textdegree}. This 'hydrophobic recovery' effect was mostly attributed to the reorientation of induced polar chemical groups into the bulk of the material. Indeed, the relative concentrations of the carbonyl and carboxyl groups at the surface decreased with the storage time and seemed to reach a plateau after 30 days.

description: We report that the spectroscopic binary ? Ursae Majoris (?mu UMa) has secondary RV variations of 471.2 days in addition to those of 230.0 days already known. Keplerian orbit analysis yields stellar mass companions of 1.6 M_Sun for the 230-d period and 0.14 M_Sun for the 471-d period. However, the HIPPARCOS photometries show a period similar to the stellar rotational period, which is one-quarter of the RV period. Variations in the bisector velocity curvature show a period of 463.6 days. We also find ~?473-day variations in the equivalent width (EW) measurements of the H_alpha and H_beta lines, whose origin is probably stellar activity. We note that the nature of 471-day variations is similar to one observed in "Sequence D" of symptotic Giant Branch (AGB) pulsating stars. We therefore conclude that the RV and the EW variations in the spectroscopic binary M giant mu UMa A originate from the complex pulsations and the chromospheric activity.

The case for inflow of the broad-line region of active galactic nuclei

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The high-ionization lines of the broad-line region (BLR) of thermal active galactic nuclei (AGNs) show blueshifts of a few hundred km/s to several thousand km/sec with respect to the low-ionization lines. This has long been thought to be due to the high-ionization lines of the BLR arising in a wind of which the far side of the outflow is blocked from our view by the accretion disc. Evidence for and against the disc-wind model is discussed. The biggest problem for the model is that velocity-resolved reverberation mapping repeatedly fails to show the expected kinematic signature of outflow of the BLR. The disc-wind model also cannot readily reproduce the red side of the line profiles of high-ionization lines. The rapidly falling density in an outflow makes it difficult to obtain high equivalent widths. We point out a number of major problems with associating the BLR with the outflows producing broad absorption lines. An explanation which avoids all these problems and satisfies the constraints of both the line profiles and velocity-resolved reverberation-mapping is a model in which the blueshifting is due to scattering off material spiraling inwards with an inflow velocity of half the velocity of the blueshifting. We discuss how recent reverberation mapping results are consistent with the scattering-plus-inflow model but do not support a disc-wind model. We propose that the anti-correlation of the apparent redshifting of H$β$ with the blueshifting of CIV is a consequence of contamination of the red wings of H$β$ by the broad wings of [O III].

description: This study is motivated by the previous work [14]. We treat 3 types of the one-dimensional quantum walks (QWs), whose time evolutions are described by diagonal unitary matrix, and diagonal unitary matrices with one defect. In this paper, we call the QW defined by diagonal unitary matrices, "the diagonal QW", and we consider the stationary distributions of generally 2-state diagonal QW with one defect, 3-state space-homogeneous diagonal QW, and 3-state diagonal QW with one defect. One of the purposes of our study is to characterize the QWs by the stationary measure, which may lead to answer the basic and natural question, "What the stationary measure is for one-dimensional QWs ?". In order to analyze the stationary distribution, we focus on the corresponding eigenvalue problems and the definition of the stationary measure.

description: The Grand Canalscape Phase II (TIGER) Shared-use Path project is a City of Phoenix (City) pathway improvement project that will complete a shared-use path along the Grand Canal from Interstate 17 (I-17) in Phoenix to the City of Tempe border at 56th Street (Figure 1, Figure 2). The pathway improvements will occur along three discontiguous segments of the Grand Canal (designated as Segments 1, 2, and 3). Phase I of the Grand Canalscape, which is in the final design stage, will provide the connection between the three segments. Numerous cultural resources have been identified throughout the Phase II area of potential effects (APE); these may be adversely affected during project construction. As a result, a Memorandum of Agreement (MOA) has been executed between the Federal Highway Administration (FHWA), the State Historic Preservation Office (SHPO), and numerous other invited signatories and consulting parties (March 6, 2017). Preconstruction geotechnical investigations were required to assist in the development of design plans. The geotechnical activities were located within the boundaries and 250-foot buffers of two Hohokam habitation sites-AZ U:9:1(ASM)/Pueblo Grande and AZ U:9:67(ASM)/La Lomita-as a result, cultural resources monitoring of geotechnical boring locations was required. As defined by the City, the area within 250 feet of the boundary of an archaeological site is considered to be the site's "buffer" and must be considered in terms of potential ground-disturbing activities.

description: Motivation: Cognitive-behavior symptoms (CBSx) represent the surface manifestation of diverse etiology. Identification and documentation of CBSx are critical to biomedical research that targets understanding the association between the symptoms and the underlying causes including genetics, aging, injury, substance use, or infection. Seeing the lack of a semantic resource of CBSx, specifically dedicated to the symptom layer, we sought to develop a CBSx Taxonomy. Methods: We defined CBSx as any observable abnormality or reduced capacity in certain cognitive or behavioral functionality. We also collected concepts concerning the impact of CBSx on life quality and daily activities. The taxonomy was iteratively developed by synthesizing knowledge from the literature, existing biomedical ontologies, and clinical instruments that assess CBSx in patients. The concepts were manually mapped to the Unified Medical Language System (UMLS). A domain expert in aging and neurogenerative diseases was consulted in curating the CBSx Taxonomy. Results: The derived taxonomy contains 258 concepts that are grouped into four major branches: cognitive symptoms, psychomotor symptoms, behavioral symptoms, and impact on life. The taxonomy has been implemented into a computable format and made available to the research community. Conclusion: By synthesizing multiple knowledge sources, we developed the CBSx Taxonomy to serve as a dedicated semantic layer for cognitive-behavioral symptoms. The taxonomy is shared publicly and is expected to benefit diverse applications including natural language processing, phenotyping, and semantic harmonization.

description: We find optimal designs for linear models using a novel algorithm that iteratively combines a Semidefinite Programming (SDP) approach with adaptive grid (AG) techniques. The search space is first discretized and SDP is applied to find the optimal design based on the initial grid. The points in the next grid set are points that maximize the dispersion function of the SDP-generated optimal design using Nonlinear Programming (NLP). The procedure is repeated until a user-specified stopping rule is reached. The proposed algorithm is broadly applicable and we demonstrate its flexibility using (i) models with one or more variables, and (ii) differentiable design criteria, such as A-, D-optimality, and non-differentiable criterion like E-optimality, including the mathematically more challenging case when the minimum eigenvalue of the information matrix of the optimal design has geometric multiplicity larger than 1. Our algorithm is computationally efficient because it is based on mathematical programming tools and so optimality is assured at each stage; it also exploits the convexity of the problems whenever possible. Using several linear models, we show the proposed algorithm can efficiently find both old and new optimal designs.

description: The quantitative investigation of the scalar Bethe-Salpeter equation in Minkowski space, within the ladder-approximation framework, is extended to include the excited states. This study has been carried out for an interacting system composed by two massive bosons exchanging a massive scalar, by adopting (i) the Nakanishi integral representation of the Bethe-Salpeter amplitude, and (ii) the formally exact projection onto the null plane. Our analysis, on one hand, confirms the reliability of the method already applied to the ground state and, on the other one, extends the investigation from the valence distribution in momentum space to the corresponding quantity in the impact-parameter space, pointing out some relevant features, like (i) the equivalence between Minkowski and Euclidean transverse-momentum amplitudes, and (ii) the leading exponential fall-off of the valence wave function in the impact-parameter space.

Masterarbeit

description: Die Fähigkeit, Sachtexte zu erschliessen, ist fächerübergreifend die Grundlage für den Lernerfolg und hat für die Selektion in die Oberstufe eine enorme Bedeutung. Die vorliegende Masterarbeit befasst sich mit der Frage, inwiefern Lernende der Primarschule im Kanton Aargau vor dem Übertritt in die leistungsgetrennte Sekundarstufe 1 Lesestrategien kennen und anwenden. Die Literatur liefert zwar theoretische Hintergründe zu Lesestrategien, zu deren tatsächlichen Umsetzung konnten bisher jedoch keine Forschungsergebnisse gefunden werden. In einer qualitativen Untersuchung werden mittels eines Leitfadeninterviews zwölf Lernende aus sechs verschiedenen Klassen befragt und die Aussagen mit einer strukturierenden Inhaltsanalyse ausgewertet. Die gewonnenen Ergebnisse werden mit einem zuvor durchgeführten Leseverständnistest und den Aussagen der Lehrpersonen zu ihrem Unterricht und zu den einzelnen Lernenden trianguliert und interpretiert. Die Ergebnisse deuten darauf hin, dass die meisten der in der Literatur erwähnten Strategien zwar bekannt sind. Häufig erwähnt und umgesetzt werden jedoch nur solche, die mit geringem Aufwand zu bewältigen sind.

description: Low density polyethylene (LDPE) surfaces have been plasma modified to improve their nanostructural and wettability properties. These modifications can significantly improve the deposition of subsequent layers such as films with specific barrier properties. For this purpose, we compare the treatments induced by two atmospheric plasma torches with different configurations (showerhead vs. linear). The modifications of LDPE films in terms of chemical surface composition and surface morphology are evidenced by X-ray photoelectron spectro-scopy, water contact angles measurements, and atomic force microscopy. A comparison between the two post-discharge treatments is achieved for several torch-to-substrate distances (gaps), treatment times, and oxygen flow rates in terms of etching rate, roughening rate, diffusion of oxygen into the subsur-face and hydrophilicity. By correlating these results with the chemical composition of the post-discharges, we identify and compare the 'species which are responsible for the chemical surface functionalization, the surface roughening, and etching.

description: Massive high-redshift quiescent compact galaxies (nicknamed red nuggets) have been traditionally connected to present-day elliptical galaxies, often overlooking the relationships that they may have with other galaxy types. We use large bulge-disk decomposition catalogues based on the Sloan Digital Sky Survey (SDSS) to check the hypothesis that red nuggets have survived as compact cores embedded inside the haloes or disks of present-day massive galaxies. In this study, we designate a "compact core" as the bulge component that satisfies a prescribed compactness criterion. Photometric and dynamic mass-size and mass-density relations are used to show that, in the inner regions of galaxies at z ~ 0.1, there are "abundant" compact cores matching the peculiar properties of the red nuggets, an abundance comparable to that of red nuggets at z ~ 1.5. Furthermore, the morphology distribution of the present-day galaxies hosting compact cores is used to demonstrate that, in addition to the standard channel connecting red nuggets with elliptical galaxies, a comparable fraction of red nuggets might have ended up embedded in disks. This result generalises the inside-out formation scenario; present-day massive galaxies can begin as dense spheroidal cores (red nuggets), around which either a spheroidal halo or a disk are formed later.

description: The CALDER project aims at developing cryogenic light detectors with high sensitivity to UV and visible light, to be used for particle tagging in massive bolometers. Indeed the sensitivity of CUORE can be increased by a factor of 3, thanks to the reduction of the $α$-background, obtained by detecting the Cherenkov light (100 eV) emitted by $β/γ$ events. Currently used light detectors have not the features required to address this task, so we decided to develop a new light detector using Kinetic Inductance Detector as a sensor. This approach is very challenging and requires an intensive R$\&$D to be satisfied. The first results of this activity are shown in the following.

Optomechanical measurement of photon spin angular momentum and optical torque in integrated photonic devices

description: Photons carry linear momentum, and spin angular momentum when circularly or elliptically polarized. During light-matter interaction, transfer of linear momentum leads to optical forces, while angular momentum transfer induces optical torque. Optical forces including radiation pressure and gradient forces have long been utilized in optical tweezers and laser cooling. In nanophotonic devices optical forces can be significantly enhanced, leading to unprecedented optomechanical effects in both classical and quantum regimes. In contrast, to date, the angular momentum of light and the optical torque effect remain unexplored in integrated photonics. Here, we demonstrate the measurement of the spin angular momentum of photons propagating in a birefringent waveguide and the use of optical torque to actuate rotational motion of an optomechanical device. We show that the sign and magnitude of the optical torque are determined by the photon polarization states that are synthesized on the chip. Our study reveals the mechanical effect of photon's polarization degree of freedom and demonstrates its control in integrated photonic devices. Exploiting optical torque and optomechanical interaction with photon angular momentum can lead to torsional cavity optomechanics and optomechanical photon spin-orbit coupling, as well as applications such as optomechanical gyroscope and torsional magnetometry.

description: In this experimental study, a flowing dielectric barrier discharge operating at atmospheric pressure is used for the splitting of CO2 into O2 and CO. The influence of the applied frequency and plasma power on the microdischarge properties is investigated to understand their role on the CO2 conversion. Electrical measurements are carried out to explain the conversion trends and to characterize the microdischarges through their number, their lifetime, their intensity and the induced electrical charge. Their influence on the gas and electrode temperatures is also evidenced through optical emission spectroscopy and infrared imaging. It is shown that, in our configuration, the conversion depends mostly on the charge delivered in the plasma and not on the effective plasma voltage when the applied power is modified. Similarly, at constant total current, a better conversion is observed at low frequencies, where a less filamentary discharge regime with a higher effective plasma voltage than that at a higher frequency is obtained.

description: We introduce a method for predicting RNA folding pathways, with an application to the most important RNA tetraloops. The method is based on the idea that ensembles of three-dimensional fragments extracted from high-resolution crystal structures are heterogeneous enough to describe metastable as well as intermediate states. These ensembles are first validated by performing a quantitative comparison against available solution NMR data of a set of RNA tetranucleotides. Notably, the agreement is better with respect to the one obtained by comparing NMR with extensive all-atom molecular dynamics simulations. We then propose a procedure based on diffusion maps and Markov models that makes it possible to obtain reaction pathways and their relative probabilities from fragment ensembles. This approach is applied to study the helix-to-loop folding pathway of all the tetraloops from the GNRA and UNCG families. The results give detailed insights into the folding mechanism that are compatible with available experimental data and clarify the role of intermediate states observed in previous simulation studies. The method is computationally inexpensive and can be used to study arbitrary conformational transitions.

description: The aim of this project was the optimisation of the lauric acid chlorination by PCl3 and identification of the phosphorus based products and by-products formed in it, understanding the reaction mechanism. The project was expanded with the synthesis and subsequent coordination to transition metals of long chain carboxylic acid and amino carboxylic acids. Optimisation of the reaction was carried out by variation of experimental parameters. With each variation, the product was analysed in order to determine the best conditions to obtain the higher conversion into lauroyl chloride. The conversion was determined by 1H NMR spectroscopy, throughout the normalisation of the peak integrals of the starting material (lauric acid) and the product (lauroyl chloride).The identification of phosphorus based products and by-products was studied in parallel through optimising the reaction.
