description: Extracellular liquid of the edible fungus Lepista irina was found to effectively degrade beta,beta-carotene. beta-Ionone, beta-cyclocitral, dihydroactinidiolide, and 2-hydroxy-2,6,6-trimethylcyclohexanone were formed as volatile breakdown products of beta,beta-carotene with myceliumfree culture supernatants, whereas beta-apo 10'-carotenal was identified as nonvolatile degradation product. The key enzyme catalyzing the oxidative cleavage of beta,beta-carotene was purified with an overall yield of 63% and a purification factor of 43. Biochemical characterization showed a molecular mass of 50.5 kDa and an isoelectric point of 3.75. Fastest beta,beta carotene degradation occurred at 34degreesC and pH values between 3.5 and 4. Degenerate oligonucleotides were derived from Nterminal and internal amino acid sequences. By means of PCRbased cDNAlibrary screening a 1284 bp cDNA was identified which showed great overall similarity to Pleurotus eryngii polyvalent peroxidases. The obtained sequence contains an open reading frame of 1083 nucleotides, encoding a polypeptide of 361 amino acids. A 30 amino acid signal peptide was identified upstream of the Nterminal sequence of the mature enzyme. The L. irina versatile peroxidase represents the first microbial enzyme capable of carotenoid degradation that has been characterized on a molecular level, proving the participation of extracellular enzymes of white rot fungi in biotic carotenoid degradation processes.

description: Locusts exhibit two interconvertible behavioral phases, solitarious and gregarious. While solitarious individuals are repelled from other locusts, gregarious insects are attracted to conspecifics and can form large aggregations such as marching hopper bands. Numerous biological experiments at the individual level have shown how crowding biases conversion towards the gregarious form. To understand the formation of marching locust hopper bands, we study phase change at the collective level, and in a quantitative framework. Specifically, we construct a partial integrodifferential equation model incorporating the interplay between phase change and spatial movement at the individual level in order to predict the dynamics of hopper band formation at the population level. Stability analysis of our model reveals conditions for an outbreak, characterized by a large scale transition to the gregarious phase. A model reduction enables quantification of the temporal dynamics of each phase, of the proportion of the population that will eventually gregarize, and of the time scale for this to occur. Numerical simulations provide descriptions of the aggregation's structure and reveal transiently traveling clumps of gregarious insects. Our predictions of aggregation and mass gregarization suggest several possible future biological experiments.

description: Nanoporous silica coatings for drug release purposes were prepared on medical implants. As substrate, we chose Bioverit® II, which is a commercial available glass-mica ceramic implant material. The coating was prepared by a dip-coating technique in which long-chain organic molecules act as placeholders for the pores. Characterization of the coatings by scanning transmission electron microscopy and X-ray diffraction showed a disordered nanoporous system with a layer thickness of 30–150 nm. The nanoporous structure was stable for about 12 h in a typical cell culture medium and rearranged to a packing of silica nanoparticles. The coating allowed cell attachment and showed excellent biocompatibility in cell culture tests independently of the particular cell type examined. In vivo, implant-tissue interactions were examined in the middle ear in a novel mouse model. Whole genome expression profiling showed no persisting inflammatory response in the presence of the implants. Release profiles of the antibiotic ciprofloxacin demonstrated that the coating is suitable for a local drug delivery. The drug loading capacity could be drastically increased after sulfonic acid modification of the Bioverit® II surface.

description: Pyrolysis of beta-lactams and beta-thiolactams led essentially to stereoselective synthesis of the high energy electron-rich Z-alkenes. Extension of this methodology to the pyrolysis of 3-allyloxy derivatives gave a simple direct route to the synthetically important 4-pentenal. These pyrolytic transformations convert aldehydes to aryloxyalkenes (a protected homologation) and 4-pentenal (a C-1 allylation and homologation). The starting 3-aryloxy and 3-allyloxy-beta-lactams were synthesized by the standard Staudinger ketene-imine [2 + 2] cycloaddition. The corresponding beta-thiolactams have readily been obtained in good yields by thiation of beta-lactams with Lawesson's reagent.

description: Formation of Z-configured double bonds in reduced polyketides is uncommon and their origins have not been extensively studied. To investigate the origin of the Z-configured double bond in the macrolide borrelidin, the recombinant dehydratase domains BorDH2 and B0rDH3 were assayed with a synthetic analogue of the predicted tetraketide substrate. The configuration of the dehydrated products was determined to be E in both cases by comparison to synthetic standards. Detailed NMR spectroscopic analysis of the biosynthetic intermediate pre-borrelidin confirmed the E,E-configuration of the fulllength polyketide synthase product. In contrast to a previously-proposed hypothesis, our results show that in this case the Z-configured double bond is not formed via dehydration from a 3 L-configured precursor, but rather as the result of a later isomerization process.

Namibian German and gender: A corpus study on the use of transferred lexical items
Creators: name: Bracke, Yannic
Publisher: name: Zenodo
Year: 2021

description: This chapter presents a quantitative corpus study of informal speech from male and female adolescent and adult Namibians with L1 German. A key feature of Namibian German is various forms of language mixing, mostly with material from English and Afrikaans. Previous sociolinguistic research, as well as statements by community members, suggest that male speakers might use more other-language material in their speech. I identified other-language material in a corpus of peer group conversations by Namibian German adolescents and adults and investigated the amount of transferred lexical items (other-language material excluding multi-word code-switches) that speakers of different age and gender used. Furthermore, I analyzed the proportion of the donor languages English and Afrikaans. Concerning the frequency of transferred lexical items, the results show an age difference between younger and older speakers, but fewer clear differences between speakers of different gender. English is the prime donor language in all groups, but subtle differences in the proportion of Afrikaans may point to interesting sociolinguistic dynamics.

description: We consider a spectrum sharing communication scenario in which a primary and a secondary users are communicating, simultaneously, with their respective destinations using the same frequency carrier. Both optimal power profile and ergodic capacity are derived for fading channels, under an average transmit power and an instantaneous interference outage constraints. Unlike previous studies, we assume that the secondary user has a noisy version of the cross link and the secondary link Channel State Information (CSI). After deriving the capacity in this case, we provide an ergodic capacity generalization, through a unified expression, that encompasses several previously studied spectrum sharing settings. In addition, we provide an asymptotic capacity analysis at high and low signal-to-noise ratio (SNR). Numerical results, applied for independent Rayleigh fading channels, show that at low SNR regime, only the secondary channel estimation matters with no effect of the cross link on the capacity; whereas at high SNR regime, the capacity is rather driven by the cross link CSI. Furthermore, a practical on-off power allocation scheme is proposed and is shown, through numerical results, to achieve the full capacity at high and low SNR

description: In this work, a very simple one-pot synthetic approach was developed to generate aqueous CdTe/CdS/ZnS type-II/type-I red-emitting nanocrystals (NCs). Strain-induced optical properties of CdTe/CdS particles having core((small))/shell((thick)) structure with a maximum quantum yield (QY(max)) similar to 57% were further improved with the overgrowth of a ZnS shell, resulting in a core((small))/shell((thick))/shell((small)) structure (QY(max) similar to 64%). The spectral properties were tuned further to the near-infrared region as the ZnS shell grew in thickness. X-ray powder diffraction (XRD) analysis and high-resolution transmission electron microscope (HRTEM) images showed the crystalline structure of NCs proving the epitaxial growth of ZnS without crystalline defects. Under continuous UV-irradiation for 5 h, the NCs did not exhibit any photo-degradation but instead displayed a photo-annealing process. These extremely photostable NCs were further characterized in terms of their cytotoxicity and their cell labeling performances. The presence of a ZnS shell was found to reduce the toxicity of the CdTe/CdS NCs. Furthermore, aptamer-conjugated NCs were successfully utilized in targeted cell imaging. Promisingly, the aptamer-NCs bioconjugates were internalized by A549 cells within 2 hours of incubation and retained their fluorescence even after 24 hours of internalization.

Results for the triton binding energy are obtained with realistic two-nucleon interactions and the Tucson-Melbourne two-pion exchange three-nucleon force and compared with previous calculations. Excellent agreement with the results of other groups is found confirming that the accuracy of present-day techniques for handling three-nucleon forces is very high indeed.

description: Redistributional issues are important in contemporary welfare states. These issues cannot be analyzed using the median voter theorem because preferences fail single-peakedness: Collective preferences are intransitive, giving rise to cyclical preferences. A suitable instrument for analyzing redistributional issues is the Colonel Blotto game. This game is older than the more familiar prisoner's dilemma, but it has been solved only recently. The article introduces the Colonel Blotto Game as well as the general structure of its solutions. Thereafter, the game's logic is illustrated using several policy examples. The two most fascinating results state that, in a political contest, it is never optimal to use pure strategies, and that the political process itself induces remarkable inequalities. © 2011 Verein für Socialpolitik.

description: In `A Bayesian Approach to Locating the Red Giant Branch Tip Magnitude (PART I),' a new technique was introduced for obtaining distances using the TRGB standard candle. Here we describe a useful complement to the technique with the potential to further reduce the uncertainty in our distance measurements by incorporating a matched-filter weighting scheme into the model likelihood calculations. In this scheme, stars are weighted according to their probability of being true object members. We then re-test our modified algorithm using random-realization artificial data to verify the validity of the generated posterior probability distributions (PPDs) and proceed to apply the algorithm to the satellite system of M31, culminating in a 3D view of the system. Further to the distributions thus obtained, we apply a satellite-specific prior on the satellite distances to weight the resulting distance posterior distributions, based on the halo density profile. Thus in a single publication, using a single method, a comprehensive coverage of the distances to the companion galaxies of M31 is presented, encompassing the dwarf spheroidals Andromedas I - III, V, IX-XXVII and XXX along with NGC147, NGC 185, M33 and M31 itself. Of these, the distances to Andromeda XXIV - XXVII and Andromeda XXX have never before been derived using the TRGB. Object distances are determined from high-resolution tip magnitude posterior distributions generated using the Markov Chain Monte Carlo (MCMC) technique and associated sampling of these distributions to take into account uncertainties in foreground extinction and the absolute magnitude of the TRGB as well as photometric errors. The distance PPDs obtained for each object both with, and without the aforementioned prior are made available to the reader in tabular form...

Consumer reactance against loyalty programs

Subjects: subject: Loyalty schemes
subject: Relationship marketing
subject: Dewey Decimal Classification::600 | Technik::650 | Management

description: Purpose - Although relationship marketing has developed into the prevailing marketing paradigm, it frequently encounters resistance from the demand side. Both management practitioners and academics indicate that at least some consumers show reactance against loyalty programs, i.e. against tactical instruments of relationship marketing. Nevertheless, relationship marketing has widely neglected reactance theory. This paper attempts to close this gap. Design/methodology/approach - Based on the fundamental principles of loyalty programs and reactance theory the paper presents a set of hypotheses on the determinants and effects of situational consumer reactance against loyalty programs. It tests these hypotheses on the basis of 388 face-to-face interviews with bookstore customers. These interviews include a between-subject manipulation on the reactance effect of economic, social-psychological, and contractual bonding potentials. To test the proposed hypotheses, the paper applies structural equation modeling with PLS. Findings - As expected, contractual bonds provoked reactance effects, while social-psychological bonds neither increased reactance, nor the perceived utility of the program. Economic bonds raised perceived utility up to a certain threshold level, from which the reactance effect dominated thereafter. Practical implications - As a consequence, a cautious and limited application of customer loyalty programs is advisable. The developed consumer reactance scale can help managers to evaluate the effects of planned or implemented customer retention measures. Originality/value - This is the first attempt to investigate situational reactance in a loyalty program setting. © Emerald Group Publishing Limited.

description: Purpose - The paper aims to introduce an efficient contact detection algorithm for smooth convex particles. Design/methodology/approach - The contact points of adjacent particles are defined according to the common-normal concept. The problem of contact detection is formulated as 2D unconstrained optimization problem that is solved by a combination of Newton's method and a Levenberg-Marquardt method. Findings - The contact detection algorithm is efficient in terms of the number of iterations required to reach a high accuracy. In the case of non-penetrating particles, a penetration can be ruled out in the course of the iterative solution before convergence is reached. Research limitations/implications - The algorithm is only applicable to smooth convex particles, where a bijective relation between the surface points and the surface normals exists. Originality/value - By a new kind of formulation, the problem of contact detection between 3D particles can be reduced to a 2D unconstrained optimization problem. This formulation enables fast contact exclusions in the case of non-penetrating particles. © Emerald Group Publishing Limited.
The role of language contact in mixed-mode group communication: On ingroup construction through multilingualism among the German-Namibian diaspora
Creators: name: Radke, Henning
Publisher: name: Zenodo
Year: 2021

description: In this paper, I analyze the role of multilingual slang within mixed-mode groups
 through the example of the German-Namibian diaspora. Unlike digital single-mode
 groups, which only exist in computer-mediated communication (CMC),
 mixed-mode groups are involved in both CMC and face-to-face communication (FTF).
 This article focuses on the latter type of groups and addresses the question as to
 how contact-induced vernacular items are resemiotized from FTF to public and
 from spoken to written mode within these groups. It is hypothesized that the
 usage of multilingual slang in FTF mode and its corresponding group cohesion
 contribute to the frequency of slang within CMC. Furthermore, this study compares a
 mixed-mode group with a digital single-mode group to investigate the effects that
 the missing social contact within the latter group has on the tendency of its
 members to use multilingual slang in CMC. The German-Namibian diaspora and their
 language practices are particularly well suited to address this topic as they draw on
 multiple linguistic resources in their FTF and CMC networks with Afrikaans,
 German, and English being the main sources. The resulting, multilingual practices are
 highly ingroup specific. The study includes a mixed-method approach combining
 traditional FTF participant observation and modern correlation analysis of CMC
 data. The aim of this study is not only to shed light on the role of multilingual
 speech within mixed-mode groups, but also to contribute to the understanding
 of the complex dynamics that occur within diasporic settings. While recognizing
 the need for multiparadigmaticity in sociological and linguistic theory, this study
 stresses the importance of holistic approaches to analyze and understand language
 in social contexts.
Results on Jet Spectra and Structure from ALICE

description: Full jet reconstruction in ALICE uses the combined information from charged and neutral particles. Essentially all jet constituents can be measured with large efficiency down to very low transverse momenta (pT > 150 MeV/c). This has the advantage to introduce a minimum bias on the jet fragmentation, in particular for low jet momenta and in the presence of quenching. In this article, we present preliminary results from reconstruction of charged jets in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV. The inclusive charged jet spectrum, the jet nuclear modification factors (R_AA, R_CP), the ratio of spectra measured with different resolution parameters and hadron-jet correlations are discussed. For pp data at the same center of mass energy, the inclusive spectrum of fully reconstructed jets and its resolution parameter dependence are reported.

description: The Department of Chemistry at the TU Munich offers the "Technische Chemie Praktikum" Laboratory Course to Chemistry and Chemical Engineering undergraduate students. The laboratory coursework includes catalysis-related experiments that are performed by the students. The course typically has ~100 students enrolled each semester and each student performs at least eight different experiments. This results in more than 800 reports generated each year that are evaluated by the designated supervisors (PhD students and Postdocs). Presently, there is no central repository for systematically storing the reports submitted by the students. Therefore, as part of NFDI4Cat, we have developed a Research Data Management tool, "RDM4Lab," for systematically storing the data generated in this Laboratory Course in compliance with FAIR (Findable, Accessible, Interoperable, and Reusable) storage principles.

description: An analytical model was developped to describe the current induced DW dynamics of a Bloch DW in the presence of an external transverse magnetic field. The model takes into account the DW deformation and the magnetization tilting in the domain. The model is compared to the results of micromagnetic simulation and an excellent agreement is obtained. In the steady state regime, the model shows that the domain tilting does not change the DW mobility. An external or current induced transverse magnetic field such as the Oersted or Rashba field can prevent the Walker breakdown leading to a higher domain wall velocity.

description: Magnetic excitations in CuCrO$_{2}$, CuCr$_{0.97}$Mg$_{0.03}$O$_{2}$, Cu$_{0.85}$Ag$_{0.15}$CrO$_{2}$, and CuCr$_{0.85}$Al$_{0.15}$O$_{2}$ have been studied by powder inelastic neutron scattering to elucidate the element substitution effects on the spin dynamics in the Heisenberg triangular-lattice antiferromagnet CuCrO$_{2}$. The magnetic excitations in CuCr$_{0.97}$Mg$_{0.03}$O$_{2}$ consist of a dispersive component and a flat component. Though this feature is apparently similar to CuCrO$_{2}$, the energy structure of the excitation spectrum shows some difference from that in CuCrO$_{2}$. On the other hand, in Cu$_{0.85}$Ag$_{0.15}$CrO$_{2}$ and CuCr$_{0.85}$Al$_{0.15}$O$_{2}$ the flat components are much reduced, the low-energy parts of the excitation spectra become intense, and additional low-energy diffusive spin fluctuations are induced. We argued the origins of these changes in the magnetic excitations are ascribed to effects of the doped holes or change of the dimensionality in the magnetic correlations.

description: A common distinction between academic and lay linguistics as regards the perception of languages is that the former remains descriptive and unevaluative in its approach to the study of language variation and change. The latter, however, sometimes views systemic differences between languages as differences of quality: some languages are seen to be more logical or effective at expressing complex thought; similarly language change is frequently viewed as language decay, with the older stages of a language seen as superior. The clear separation between academic linguistics as essentially descriptive in orientation versus lay linguistics as evaluative toward change does not always hold in such a clear-cut way when it comes to attitudes toward change in smaller languages. In this chapter, we present evidence from metalinguistic comments on North Frisian to discuss to what extent such a clear separation between description and evaluation is indeed maintained by academic linguists studying this language. We aim to show that there is a remarkable similarity in the evaluation of language contact across different types of scholarly and public discourse.

description: The main purpose of this paper is to show that the multiplication of a Schubert polynomial of finite type $A$ by a Schur function, which we refer to as Schubert vs. Schur problem, can be understood from the multiplication in the space of dual $k$-Schur functions. Using earlier work by the second author, we encode both problems by means of quasisymmetric functions. On the Schubert vs. Schur side, we study the poset given by the Bergeron-Sottile's $r$-Bruhat order, along with certain operators associated to this order. On the other side, we connect this poset with a graph on dual $k$-Schur functions given by studying the affine grassmannian order of Lam-Lapointe-Morse-Shimozono. Also, we define operators associated to the graph on dual $k$-Schur functions which are analogous to the ones given for the Schubert vs. Schur problem.

description: We investigate gravitational instability (GI) of rotating, vertically-stratified, pressure-confined, polytropic gas disks using linear stability analysis as well as analytic approximations. The disks are initially in vertical hydrostatic equilibrium and bounded by a constant external pressure. We find that GI of a pressure-confined disk is in general a mixed mode of the conventional Jeans and distortional instabilities, and is thus an unstable version of acoustic-surface-gravity waves. The Jeans mode dominates in weakly confined disks or disks with rigid boundaries. When the disk has free boundaries and is strongly pressure-confined, on the other hand, the mixed GI is dominated by the distortional mode that is surface-gravity waves driven unstable under own gravity and thus incompressible. We demonstrate that the Jeans mode is gravity-modified acoustic waves rather than inertial waves and that inertial waves are almost unaffected by self-gravity. We derive an analytic expression for the effective sound speed c_eff of acoustic-surface-gravity waves. We also find expressions for the gravity reduction factors relative to a razor-thin counterpart, appropriate for the Jeans and distortional modes. The usual razor-thin dispersion relation after correcting for c_eff and the reduction factors closely matches the numerical results obtained by solving a full set of linearized equations. The effective sound speed generalizes the Toomre stability parameter of the Jeans mode to allow for the mixed GI of vertically-stratified, pressure-confined disks.

description: We have studied the magnetic, magnetocaloric and magnetotransport properties of RSn1+xGe1-x(R=Gd, Tb, Er; x=0.1) series by means of magnetization, heat capacity and resistivity measurements. It has been found that all the compounds crystallize in the orthorhombic crystal structure described by the centrosymmetric space group Cmcm (No. 63). The magnetic susceptibility and heat capacity data suggest that all the compounds are antiferromagnetic. Large negative values of θp in case of GdSn1.1Ge0.9 and TbSn1.1Ge0.9 indicate that strong antiferromagnetic interactions are involved, which is also reflected in the magnetization isotherms. On the other hand ErSn1.1Ge0.9 shows weak antiferromagnetic interaction. The heat capacity data have been analyzed by fitting the temperature dependence and the values of θD and γ have been estimated. Among these three compounds, ErSn1.1Ge0.9 shows considerable magnetic entropy change of 9.5 J/kg K and an adiabatic temperature change of 3.2 K for a field of 50 kOe. The resistivity data in different temperature regimes have been analyzed and the dominant contributions have been identified. All the compounds show small but positive magnetoresistance.

description: The Künneth Theorem for equivariant (complex) K-theory K^*_G, in the form developed by Hodgkin and others, fails dramatically when G is a finite group, and even when G is cyclic of order 2. We remedy this situation in this very simplest case G = Z/2 by using the power of RO(G)-graded equivariant K-theory.

description: Local natural resource management in its diverse manifestations holds core to its principles that the marginal and vulnerable households are empowered to manage valuable natural resources to improve social and economic equality and conserve biodiversity. Yet studies aiming to identify the impacts often show inconsistent results. Through constructing an integrated Environmental and Social Accounting Matrix (ESAM), we aim to assess how natural resources are used in different sectors and by different livelihoods, thus delivering different direct and indirect benefits to the community. The study was conducted in Namibia’s Sikunga Conservancy, which manages wildlife and fish resources in the Zambezi region. Our village-level ESAM shows an economic structure that strongly disadvantages remote households and identifies a small sector of the economy that benefits significantly from the use of natural resources. The ESAM approach is able to isolate undesirable socioeconomic developments such as unequal benefit sharing, which hinders community development. © 2016, © The Author(s) 2016.

description: The ability for bowlers to successfully bowl different length fast bowling deliveries is an important but challenging task. This study investigated fast bowling pitch length delivery types using a full body three-dimensional kinematic and kinetic analysis. 21 county fast bowlers performed 48 deliveries (12 yorkers, 12 bouncers and 24 stock balls) with an eighteen camera (MX3) Vicon motion analysis system (250 Hz) and a Kistler force plate (1000 Hz) recording each trial. The bowlers were found to be most consistent at bowling bouncers (98% success rate) compared to stock and yorker deliveries (46% and 25% success rate respectively). Repeated measures ANOVA revealed significant differences in ball release angle and ball release height between the three delivery types. Ball – finger 2D orientation angle, wrist angle, 2D orientation of hand segment, thoracic angle and 2D orientation of the thoracic were the main technique parameters which explained from 31% to 89% of the variation in ball release angle and ball release height percentage predictive equations. The thoracic angle and wrist angle time histories (back foot contact to ball release) had periods that were significantly different across the three types of delivery. Furthermore, SPM analysis revealed significant changes (p = 0.03) in wrist moments for bouncers compared with yorkers and stock balls between front foot contact and ball release. In conclusion, this study provides an understanding of the technique parameters most associated with different length deliveries in cricket fast bowling. These results provide a foundation for coaching and future research, in particularly investigating the kinematic and kinetic factors linked with different length fast bowling deliveries and different action classifications.

description: This paper shows a new phenomenon in higher cluster tilting theory. For each positive integer d, we exhibit a triangulated category C with the following properties. On the one hand, the d-cluster tilting subcategories of C have very simple mutation behaviour: Each indecomposable object has exactly d mutations. On the other hand, the weakly d-cluster tilting subcategories of C which lack functorial finiteness can have much more complicated mutation behaviour: For each 0 ≤ ℓ ≤ d-1, we show a weakly d-cluster tilting subcategory Tℓ which has an indecomposable object with precisely ℓ mutations. The category C is the algebraic triangulated category generated by a (d + 1)-spherical object and can be thought of as a higher cluster category of Dynkin type A∞. © 2015 by De Gruyter.

East Frisians ``achter de Penn'': Language and identity in correspondences to a German newspaper in America
Creators: name: Rocker, Maike H.
Publisher: name: Zenodo
Year: 2021

description: This study examines 369 correspondence letters written between 1944 and 1971 to
 the Ostfriesen-Zeitung (OZ), a newspaper published in Iowa for a group of Low
 German-speaking East Frisian immigrants to the USA. Although readers typically
 lived in small, rural Midwestern towns which were geographically dispersed, they
 were highly interconnected and honored their shared roots. While the
 correspondence letters are predominantly written in High German (HG) and typically report
 news of more serious events (e.g., anniversaries, visits, or obituaries), Low German
 (LG), which is usually a spoken language, was extended into the written domain by
 some authors. Although the amount of LG usage is limited, its pragmatic purposes
 are highly predictable. LG is used to refer to cultural concepts, in reported speech,
 personal opinions and anecdotes, as well as in humoristic reference to other peo-
 ple. Through the OZ and the correspondence letters published in it, an East Frisian-
 American identity and a sense of community and belonging was promoted, which
 helped to maintain both HG and LG well into the 20th century.

description: Perturbative gluon exchange interaction between quark and antiquark, or in a 3q system, is enhanced in magnetic field and may cause vanishing of the total q\bar q or 3q mass, and even unlimited decrease of it - recently called the magnetic collapse of QCD. The analysis of the one-loop correction below shows a considerable softening of this phenomenon due to q\bar q loop contribution, similarly to the Coulomb case of QED, leading to approximately logarithmic dumping of gluon exchange interaction at large magnetic field.
