description: Around the Persian (Arabian) Gulf, a considerable volume of freshwater is obtained by desalination of seawater with the residual brine dumped back into the Gulf. This discharge of saltier waters impacts the marine ecosystem and may also affect dynamic and thermodynamic processes. Here, a fully non-linear, high-resolution numerical model is used to investigate the physical impacts of brine discharge into the Gulf. Twin runs were executed. One with and another without brine discharge at specific points. The results show that, when brine is injected, surface gravity waves irradiate from the locations and induce perturbations in other thermodynamic variables in the far field. Instead of attenuating, the anomalies have long term impact. The differences between the two experiments show marked seasonal and spatial variability. The largest differences occur during the summer and are located mainly along the axis of the Gulf's deeper channel. After 5 years of run, a budget calculation shows basin wide saline increase of about 0.2 g/kg, in agreement with previous studies. This might appear small when compared with the present Gulf mean salinity. However, the small change seems to be associated with significant variability in the spatial distribution and in the seasonal variability at different locations. It is found that there are regions in the Gulf where the standard deviation may represent serious consequences for living organisms in the marine environment.

description: A notable feature of the elephant trunk is the pronounced wrinkling that enables its great flexibility. Here, we devise a general mathematical model that accounts for the characteristic skin wrinkles formed during morphogenesis in the elephant trunk. Using physically realistic parameters and operating within the theoretical framework of nonlinear morphoelasticity, we elucidate analytically and numerically the effect of skin thickness, relative stiffness, and differential growth on the physiological pattern of transverse wrinkles distributed along the trunk. We conclude that since the skin and muscle components have similar material properties, geometric parameters, such as curvature, play an important role. In particular, our model predicts that, in the proximal region close to the skull, where the curvature is lower, fewer wrinkles form and will form sooner than in the distal narrower region, where more wrinkles develop. Similarly, less wrinkling is found on the ventral side, which is flatter, compared to the dorsal side. In summary, the mechanical compatibility between the skin and the muscle enables them to grow seamlessly, while the wrinkled skin acts as a protective barrier that is both thicker and more flexible than the unwrinkled skin.

description: Системы защиты от хлопковой совки разработаны главным образом для хлопчатника, паслёновых культур и кукурузы. Они включают применение химических и биологических мер. Для сои система борьбы с хлопковой совкой до настоящего времени не была разработана. В результате исследования при защите сои от хлопковой совки рекомендовано применение интегрированной системы, включающей пестициды химического и биологического происхождения. Из испытанных химических препаратов наиболее эффективными оказались Авант, КЭ (150 г/л) и баковая смесь Авант, КЭ (150 г/л) + Децис Эксперт, КЭ (100 г/л). Для предотвращения формирования резистентности совки к препаратам предпочтительнее применение баковых смесей. Химические препараты рекомендовано применять только при превышении ЭПВ вредителя. С целью перехода к экологически безопасной системе защиты сои от хлопковой совки рекомендуется применение бактериальных препаратов Бикол (Битоксибациллин), особенно при выращивании продукции для детского и диетического питания. При численности гусениц, не превышающей ЭПВ, предпочтительно использовать также систему биологической защиты сои от хлопковой совки с использованием биологических препаратов и выпусков энтомофагов (трихограммы и бракона). Максимальный уровень рентабельности получен при применении баковой смеси инсектицидов Авант, КЭ (150 г/л) + Децис Эксперт, КЭ (100 г/л) с нормой расхода 0,1 л / га – 151,5 %. Рентабельность биологического препарата Бикол, Ж (1500 EA/мл) 3,0 л/га составила 119,5 %.

description: Most attention to improving vacuum thermionic energy conversion device (TEC) technology has been on improving electron emission with little attention to collector optimization. A model was developed to characterize the output characteristics of a TEC where the collector features negative electron affinity (NEA). According to the model, there are certain conditions for which the space charge limitation can be reduced or eliminated. The model is applied to devices comprised of materials reported in the literature, and predictions of output power and efficiency are made, targeting the sub-1000K hot-side regime. By slightly lowering the collector barrier height, an output power of around $1kW$, at $\geq 20%$ efficiency for a reasonably sized device ($\sim 0.1m^{2}$ emission area) can be achieved.

description: Two novel rare earth compounds have been synthesized using the previously reported (S)-MonoThioBINOL [(S)-H2-MTB], (S)-2-hydroxy-2′-mercapto-1,1′-binaphthyl). We have shown here that while the H-bonded complex containing TMG-H+ (tetramethyl guanidium cation) maintains the structure that the analogous BINOLate complex adopts, the complex with lithium cations in the secondary coordination sphere crystallizes as an ‘–ate’ complex with an outer sphere lithium counter cation solvated by DME.

description: We calculate the leading radiative corrections to the axial current in the chiral separation effect in dense QED in a magnetic field. Contrary to the conventional wisdom suggesting that the axial current should be exactly fixed by the chiral anomaly relation and is described by the topological contribution on the lowest Landau level in the free theory, we find in fact that the axial current receives nontrivial radiative corrections. The direct calculations performed to the linear order in the external magnetic field show that the nontrivial radiative corrections to the axial current are provided by the Fermi surface singularity in the fermion propagator at nonzero fermion density.

description: The stacked spectral energy distribution (SED) of Multiband Imaging Photometer for Spitzer (MIPS) 24$μm$ detected Lyman break galaxies (MIPS-LBGs) is fitted by means of spectro-photometric model GRASIL with an "educated" fitting approach which benefits from results of chemical evolution models. The star formation rate(SFR)-age-metallicity degeneracies of SED modelling are broken by using SFH and chemical enrichment history suggested by chemical models, which also provide dust mass, dust abundance and chemical elements locked in dust component. We derive the total mass $M_{tot}$, stellar mass $M_{\ast}$, gas mass $M_{g}$, dust mass $M_{d}$, age and SFR of the stacked MIPS-LBG in a self-consistent way. Our estimate of $M_{\ast}= 8\times 10^{10}$ agrees with other works based on UV-optical SED fitting. We suggest that MIPS-LBGs at $z\sim3$ are young (0.3-0.6 Gyr), massive ($M_{tot} \sim 10^{11} M_{\odot}$), dusty ($M_{d} \sim 10^{8} M_{\odot}$), metal rich ($Z \sim Z_{\odot} $) progenitors of elliptical galaxies suffering a strong burst of star formation (SFR $\sim 200 M_{\odot}/yr$). Our estimate of $M_{d}=7 \times 10^{7} M_{\odot}$ of the stacked MIPS-LBG is about a factor of eight lower than the estimated value based on single temperature grey-body fitting, suggesting that self-consistent SED models are needed to estimate dust mass. By comparing with the Milky Way molecular cloud and dust properties, we suggest that denser and dustier environments and flatter dust size distribution are likely in high redshift massive star forming galaxies. These dust properties, as well as the different types of SFHs, can cause different SED shapes between high redshift star-forming ellipticals and local star-burst templates. This discrepancy of SED shapes could in turn explain the non detection at submillimeter wavelengths, of IR luminous ($L_{IR} \succeq 10^{12} L_{\odot} $) MIPS-LBGs.

description: The recent discovery of a superconductivity signature in La3Ni2O7-δ under a pressure of 14 GPa, with a superconducting transition temperature of around 80 K, has attracted considerable attention. An important aspect of investigating electronic structures is discerning the extent to which the electronic ground state of La3Ni2O7-δ resembles the parent state of the cuprate superconductor, a charge transfer insulator with long-range antiferromagnetism. Through X-ray absorption spectroscopy, we have uncovered the crucial influence of oxygen ligands on the electronic ground states of the Ni ions, displaying a charge transfer nature akin to cuprate but with distinct orbital configurations. Both in-plane and out-of-plane Zhang-Rice singlets associated with Ni d_(x^2-y^2 ) and d_(z^2) orbitals are identified, together with a strong interlayer coupling through inner apical oxygen. Additionally, in La3Ni2O7-δ films, we have detected a superlattice reflection (1/4, 1/4, L) at the Ni L absorption edge using resonant X-ray scattering measurements. Further examination of the resonance profile indicates that the reflection originates from the Ni d orbitals. By evaluating the reflection's azimuthal angle dependence, we have confirmed the presence of collinear antiferromagnetic spin ordering and charge-like anisotropy ordered with the same periodicity. Notably, our findings reveal a microscopic relationship between these two components in the temperature dependence of the scattering intensity of the reflection. This investigation enriches our understanding of high-temperature superconductivity in La3Ni2O7-δ under high pressure.

description: Objective: This study examines family strategies for coping and adaptation to social disruption from the 2010 Deepwater Horizon oil spill (DHOS) in south Louisiana. Background: The DHOS is a technological disaster of unprecedented scale and ongoing impact, including the socioeconomic disruption of families. Method: Using data from focus groups, grounded‐theory methods informed a thematic analysis of spill‐related economic loss and coping mechanisms among families in the spill‐affected region. Results: Key findings were as follows: (a) long‐term economic impacts persisted but were nuanced and differed across places; (b) for families living in multistressor environments, concerns about the DHOS spilled over into other aspects of social functioning and became enmeshed with perceptions of other environmental stressors; and (c) economic exposure after the DHOS affected families differently based on social position and community social structure. Conclusion: This study contributes to existing knowledge on technological disaster and family resilience in the face of environmental shocks and stressors, underscoring the utility of the conservation of resources model of stress in this area of research. Implications: This research offers information about family‐level response to oil spill impacts and may be of interest to policymakers and practitioners who work to support resilience in disaster contexts.

description: A gas-cooled, cylindrical, nuclear reactor is used as the basis in the theoretical derivation of the coolant's enthalpy increase and pressure loss across the reactor.  Turbulent flow is assumed in the coolant passages of the reactor, and the Reynolds analogy is used as the basis for correlating the heat transfer coefficient and the friction coefficient.

The general equations are derived and two examples, a nuclear-hydrogen rocket and a ramjet, are given to demonstrate applications of the general results.

description: Talent has emerged as a potentially important source of competitive advantage in today's corporate world. It is the foundation for establishing an organisation that is capable of learning, inventing, and adapting, as well as implementing new procedures. Talent management is defined as "extra management processes and opportunities put in place for persons in the business who are seen to be gifted." This article aims to provide aguidance for racers who want to grow their businesses by extending their success on racing tracks to business routes. This post is based on data acquired from in-depth interviews with three business owners who are also racers. During the interview, opinion on benchmarking via talent in motorsports and companies was requested. This research showed the necessity of talent management as seen through the lens of how great performers in motorsports have managed to drive their businesses while still generating great achievements on the race courses. The function of the business owner will be to act as a catalyst for increasing the output from bike manufacture. They might also help fund research and development so that nice motorcycles with high performance and durability may be produced.

Experiments on the flow at the nose of a thin airfoil
Creators: name: Doering, Eugene Richard
Publisher: name: California Institute of Technology
Year: 1959
Subjects: Aeronautics

description: An investigation of a family of two-dimensional airfoils was conducted in the Merrill Wind Tunnel at California Institute of Technology, to determine experimentally the effect of camber on an airfoil that stalls at the nose, and to compare the results with a simplified thin airfoil theory, which requires that flow conditions at the nose be similar.

The nine percent thick models had cambers of zero, three, and six percent, and a fourth model with six percent camber had a rear slot at about 70 percent chord.

Tests conducted at Reynolds Numbers of 640,000 and 840,000 showed that the addition of camber to a nose-stalling airfoil tended to make it a trailing-edge staller or partially so, but that by use of the slot, the stall was shifted back to the nose.

Good agreement was obtained in the theoretical and experimental determination of maximum lift for the slotted airfoil, but not for the angle at which this occurred.

Constraints from parton distributions in the deep-inelastic region, together with new data on parity-violating electron scattering in the resonance region, result in significantly smaller uncertainties on the corrections compared to previous estimates. At the kinematics of the Qweak experiment, we determine the gamma-Z box correction to be ReBox^V_{gamma-Z} = (5.57 +- 0.36) x 10^{-3}. The new constraints also allow precise predictions to be made for parity-violating deep-inelastic asymmetries on the deuteron.

Measuring Inaccuracy in Travel Demand Forecasting: Methodological Considerations Regarding Ramp Up and Sampling
Creators: name: Flyvbjerg, Bent
Publisher: name: arXiv
Year: 2013
Subjects: subject: General Finance (q-fin.GN)
subject: FOS: Economics and business

description: Project promoters, forecasters, and managers sometimes object to two things in measuring inaccuracy in travel demand forecasting: (1) using the forecast made at the time of making the decision to build as the basis for measuring inaccuracy and (2) using traffic during the first year of operations as the basis for measurement. This paper presents the case against both objections. First, if one is interested in learning whether decisions about building transport infrastructure are based on reliable information, then it is exactly the traffic forecasted at the time of making the decision to build that is of interest. Second, although ideally studies should take into account so-called demand "ramp up" over a period of years, the empirical evidence and practical considerations do not support this ideal requirement, at least not for large-N studies. Finally, the paper argues that large samples of inaccuracy in travel demand forecasts are likely to be conservatively biased, i.e., accuracy in travel demand forecasts estimated from such samples would likely be higher than accuracy in travel demand forecasts in the project population. This bias must be taken into account when interpreting the results from statistical analyses of inaccuracy in travel demand forecasting.

description: We show that results from the Planck satellite reported in 2013 are consistent with the simplest cyclic models for natural parameter ranges i.e., order unity dimensionless coefficients, assuming the standard entropic mechanism for generating curvature perturbations. With improved precision, forthcoming results from Planck and other experiments should be able to test the parameter ranges by confirming or refuting the core predictions - i.e., no observable primordial B-mode polarization and detectable local non-gaussianity. A new prediction, given the Planck 2013 constraints on the bispectrum, is a sharp constraint on the local trispectrum parameter g_{NL}; namely, the simplest models predict it is negative, with g_{NL} < -1700.

description: The ARIADNE infrastructure provides search and access to data from research on archaeological and cultural heritage deposited in repositories. It enables the archaeological community to share, find and access data in dispersed repositories for use across institutional and national as well as disciplinary boundaries. Integration of (meta)data in the ARIADNE search and access portal is based on FAIR data principles and application of advanced domain standards. The integration enables greater visibility of available datasets and their providers and increases the potential of data discovery, access and reuse. Among the requirements to reap the benefits offered by the ARIADNE initiative are available repositories that are appropriate for archaeological data, open data policies and guidelines, especially of heritage authorities, and removal of barriers of researchers to make reusable data available through open access repositories. Particularly required is the interest of repositories to make interoperable data searchable through the ARIADNE portal, i.e., implement the data standards the ARIADNE initiative promotes to increase the “FAIRness” of archaeological data.

description: I. DERIVATIVES OF SPIRO(3,3) HEPTANETETRACARBOXYLIC ACID:

The isolation of the isoamyl ester of spiroheptanetetra-carboxylic acid, prepared by the condensation of sodiomalonic ester with pentaerythrityl tetrabromide in isoamyl alcohol is reported. The synthetic method is that of Fecht as modified by Backer and Schurink. Pentaerythrityl benzenesulfonate is substituted for the bromide in the reaction with the malonic ester, but the yield is found to be much poorer. Attempts to prepare the ethyl ester of spiroheptanetetracarboxylic acid by using pentaerythrityl benzenesulfonate in ethyl alcohol solvent, and pentaerythrityl bromide in excess malonate and xylene solvents are described. These experiments did not produce a practical synthesis of the ethyl ester.

The unsuccessful attempt to reduce the isoamyl ester of spiroheptanetetracarboxylic acid with lithium aluminum hydride is described.

II. ATTEMPTED NEW SYNTHESIS OF CIS-2-BUTENE-,4-DIOL:

A synthesis of cis-2-butene-1,4-diol by the reduction of maleic anhydride with lithium aluminum hydride is attempted. Two experiments are described, one of which employs an aqueous system in the isolation of the product, the other a non-aqueous system. No amount of any consequence of the diol was obtained. A discussion of lithium aluminum hydride as a reducing agent is included.

description: Risk, including economic risk, is increasingly a concern for public policy and management. The possibility of dealing effectively with risk is hampered, however, by lack of a sound empirical basis for risk assessment and management. The paper demonstrates the general point for cost and demand risks in urban rail projects. The paper presents empirical evidence that allow valid economic risk assessment and management of urban rail projects, including benchmarking of individual or groups of projects. Benchmarking of the Copenhagen Metro is presented as a case in point. The approach developed is proposed as a model for other types of policies and projects in order to improve economic and financial risk assessment and management in policy and planning.

description: The K-matrix, also known as the "Wigner reaction matrix" in nuclear scattering or "impedance matrix" in the electromagnetic wave scattering, is given essentially by an M x M diagonal block of the resolvent (E-H)^{-1} of a Hamiltonian H. For chaotic quantum systems the Hamiltonian H can be modelled by random Hermitian N x N matrices taken from invariant ensembles with the Dyson symmetry index beta=1,2,4. For beta=2 we prove by explicit calculation a universality conjecture by P. Brouwer which is equivalent to the claim that the probability distribution of K, for a broad class of invariant ensembles of random Hermitian matrices H, converges to a matrix Cauchy distribution with density ${\cal P}(K)\propto \left[\det{(λ^2+(K-ε)^2)}\right]^{-M}$ in the limit $N\to \infty$, provided the parameter M is fixed and the spectral parameter E is taken within the support of the eigenvalue distribution of H. In particular, we show that for a broad class of unitary invariant ensembles of random matrices finite diagonal blocks of the resolvent are Cauchy distributed. The cases beta=1 and beta=4 remain outstanding.

No flares from Gamma-Ray Burst afterglow blast waves encountering sudden circumburst density change

description: Afterglows of gamma-ray bursts are observed to produce light curves with the flux following power law evolution in time. However, recent observations reveal bright flares at times on the order of minutes to days. One proposed explanation for these flares is the interaction of a relativistic blast wave with a circumburst density transition. In this paper, we model this type of interaction computationally in one and two dimensions, using a relativistic hydrodynamics code with adaptive mesh refinement called RAM, and analytically in one dimension. We simulate a blast wave traveling in a stellar wind environment that encounters a sudden change in density, followed by a homogeneous medium, and compute the observed radiation using a synchrotron model. We show that flares are not observable for an encounter with a sudden density increase, such as a wind termination shock, nor for an encounter with a sudden density decrease. Furthermore, by extending our analysis to two dimensions, we are able to resolve the spreading, collimation, and edge effects of the blast wave as it encounters the change in circumburst medium. In all cases considered in this paper, we find that a flare will not be observed for any of the density changes studied.

description: The Economist recently reported that infrastructure spending is the largest it is ever been as a share of world GDP. With $22 trillion in projected investments over the next ten years in emerging economies alone, the magazine calls it the "biggest investment boom in history." The efficiency of infrastructure planning and execution is therefore particularly important at present. Unfortunately, the private sector, the public sector and private/public sector partnerships have a dismal record of delivering on large infrastructure cost and performance promises. This paper explains why and how to solve the problem.

description: The X-ray Integral Field Unit (X-IFU) is an instrument of ESA's future NewAthena space observatory, with the goal to provide high-energy resolution ($<$ 4 eV at X-ray energies up to 7 keV) and high-spatial resolution (9") spectroscopic imaging over the X-ray energy range from 200 eV to 12 keV, by means of an array of about 1500 transition-edge sensors (TES) read out via SQUID time-division multiplexing (TDM). A TDM-based laboratory test-bed has been assembled at SRON, hosting an array of $75\times 75\ \upmu$m$^2$ TESs that are read out via 2-column $\times$ 32-row TDM. A system component that is critical to high-performance operation is the wiring harness that connects the room-temperature electronics to the cryogenic readout componentry. We report here on our characterization of such a test-bed, whose harness has a length close to what envisioned for X-IFU, which allowed to achieve a co-added energy resolution at a level of 2.7~eV FWHM at 6~keV via 32-row readout. In addition, we provide an outlook on the integration of TDM readout into the X-IFU Focal-Plane Assembly Development Model.

Some features of the geology of the north Vancouver area.

description: The Coast Range Batholith north of Vancouver, British
Columbia, comprises within the mapped area rocks ranging in
composition from granitic pegmatite to gabbro.  The most
widespread rock is the Capilano quarts-diorite which is
markedly heterogeneous, and contains on the average about
3% inclusions. In relative abundance, the quarts-diorite
is followed by the Hollyburn granodiorite, More than 80%
of the batholithic rock is of these two types. Within the
batholith are several roof pendants composed of early Mesozoic volcanics and sediments.  One of the most interesting features within the area are the dykes. Although many lie wholly within the batholith, evidence is presented which indicates that they are pre-batholithic. These pro-batholithic dykes are thought to have a significant bearing on the problem of emplacement of the batholithic rock.

The marked heterogeneity of most of the batholithic rock, the distribution and alteration of the inclusions,
microscopic textural relationships, and certain other data
suggest that much of the exposed batholithic rock occupied
its present position by some process of replacement rather
than by forceful intrusion. It is recognized, however,
that due to the nature of the country, the scope of the work, and to some extent due to the nature of the problem, the evidence is not conclusive.
title: Orestes inside and beyond intrafamilial violence: a literary study of his role in the politics of language and metapoetics in Archaic and early Classical Greek Literature
Creators: name: Kamini, Doukissa
Publisher: name: University of Reading
Year: 2024

description: This thesis discusses the mythical figure of Orestes in Archaic and early Classical Greek literature in order to examine his literary and political functions within the various narratives. The basic argument revolves around the principle that a Close Reading of those texts will show that literary dimensions and political connotations of his function share a common network of vocabulary and imagery which eventually makes them intertwined parts of the narrative. I shall employ Narratology for a connection between such an interaction and the plot-making process. I shall depart from analyses that examine political aspects on the level of historical contemporality, and I shall discuss literary politics, i.e. the political, legal, and social aspects that are shaped within the narrative, depend on and interact with the literary and mythical past. As I shall show, a linguistic roadmap to the hero’s profile will show that such connotations around him become inter-textual and intra-textual features intertwined with literary and metapoetical dimensions of the narrative, the combination of which shapes its generic identity. In the first chapter, I shall discuss Orestes’ political coming-of-age process as a means for the reestablishment of Odysseus’ authority after the Trojan War and for the formation of a metapoetical reading of the Odyssey. In the second chapter, I shall discuss three versions of Orestes as a Spartan hero in order to explore to what extent his profile reshapes as he moves from epic to lyric and historiographic versions. In the third chapter, I shall provide a linguistic map to Orestes in the Oresteia and a specific reading of the trilogy based on his action as well as a narratological approach to his trial and the alliance with Athens. In the fourth chapter, I shall discuss the intertextual and metapoetical relation between the Oresteia and previous versions around Orestes.
Relations between supersymmetric structures in UV and IR for $\mathcal{N}=4$ bad theories

description: We investigate options for the structure of the infrared fixed points of $\mathcal{N}=4$ bad theories in three dimensions. Unitarity constraints allow a number of possibilities, not necessarily a product of an interacting $\mathcal{N}=4$ SCFT and free theories. For each option we provide relations between the UV and IR $R-$symmetry groups. For some of them we give examples. In particular, the $\mathcal{N}4$ SU(2) SYM with two fundamental hypermultiplets is an example of a bad theory which flows to an interacting irreducible SCFT in the IR. The question of whether all the options are realized remains open.

How Planners Deal with Uncomfortable Knowledge: The Dubious Ethics of the American Planning Association

Publisher: name: arXiv
Year: 2013
Subjects: subject: General Finance (q-fin.GN)

description: With a point of departure in the concept "uncomfortable knowledge," this article presents a case study of how the American Planning Association (APA) deals with such knowledge. APA was found to actively suppress publicity of malpractice concerns and bad planning in order to sustain a boosterish image of planning. In the process, APA appeared to disregard and violate APA's own Code of Ethics. APA justified its actions with a need to protect APA members' interests, seen as preventing planning and planners from being presented in public in a bad light. The current article argues that it is in members' interest to have malpractice critiqued and reduced, and that this best happens by exposing malpractice, not by denying or diverting attention from it as APA did in this case. Professions, organizations, and societies that stifle critique tend to degenerate and become socially and politically irrelevant "zombie institutions." The article asks whether such degeneration has set in for APA and planning. Finally, it is concluded that more debate about APA's ethics and actions is needed for improving planning practice. Nine key questions are presented to constructively stimulate such debate.

Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences

description: The Pacoima Hills lie between Foothill Boulevard and the San Fernando Road, three miles southeast of San Fernando, California. In this area are exposed Jurassic(?) granodiorite intruded in older gneiss, and a mid Miocene Topango (?) sedimentary section lying in both fault and sedimentary contact with the intrusive complex. Two distinct lava flows and a small laccolith of andesite occur within the Topango (?) formation. The principal structural feature is an anticline plunging steeply northward. An upward acting force is postulated to have produced this anticline; upon cessation of the force, normal faulting occurred with consequent down-dropping of north-south blocks.
Detecting transition radiation from a magnetic moment

description: Electromagnetic radiation can be emitted not only by particle charges but also by magnetic moments and higher electric and magnetic multipoles. However experimental proofs of this fundamental fact are extremely scarce. In particular, the magnetic moment contribution has never been observed in any form of polarization radiation. Here, we propose to detect it using vortex electrons carrying large orbital angular momentum (OAM) \ell. The relative contribution of the OAM-induced magnetic moment, \ell \hbar ω/E_e, becomes much larger than the spin-induced contribution \hbar ω/E_e, and it can be observed experimentally. As a particular example, we consider transition radiation from vortex electrons obliquely incident on an interface between a vacuum and a dispersive medium, in which the magnetic moment contribution manifests itself via a left-right angular asymmetry. For electrons with E_e = 300 keV and \ell = 100-1000, we predict an asymmetry of the order of 0.1%-1%, which could be measured with existing technology. Thus, vortex electrons emerge as a new tool in the physics of electromagnetic radiation.
