Writing in Real Time: Emergent Poetics from Whitman to the Digital by Paul Jaussen

Reviewed by: Writing in Real Time: Emergent Poetics from Whitman to the Digital by Paul Jaussen Heather A. Love Writing in Real Time: Emergent Poetics from Whitman to the Digital. Paul Jaussen. Cambridge: Cambridge University Press, 2017. Pp. 239. $99.00 (cloth); $80.00 (eBook). The opening pages of Paul Jaussen's Writing in Real Time introduce readers to "emergence," a concept borrowed from systems theory wherein "small, local actions or actors can produce large, global, and unexpected effects" (2). The "complex adaptive systems" that demonstrate this principle at work range from the shifting, swooping shape of a flock of birds in flight to the evolving, adaptable aesthetics of the long poem—the latter being the focus of this book. Within these systems, Jaussen explains, "first-order actions produce unexpected second-order effects," and those effects in turn "redirect the behavior of the first order, transforming the system as a whole and shaping its encounters with the environment" (2). In centering its analytic framework on a term like "emergence," one of this study's main goals is to "demonstrate the broad flexibility of systems thinking for analyzing poetry" (37). Jaussen's ambitions towards this end are twofold: on the one hand, to show how "systems theory offers us a powerful alternative for thinking about the relationship between form and content, poiesis and history, creativity and change," and, on the other, to posit that "literary texts may be a neglected yet crucial site for apprehending the concepts of scientific discourse, including systems theory" (25, 2). In and of itself, this overall premise—that the disciplines of systems theory and literary study can be productively brought into contact with each other—represents one of the book's most compelling features. If we look to recent trends in modernist literary studies, the argument reads as an innovative addition not only to the extensive body of existing scholarship that reads early twentieth-century literature alongside technological development but also to the more recent embrace of media studies as a productive framework for considering this literature as part of wider historical, technical, and communicative contexts. As Jaussen convincingly demonstrates throughout Writing in Real Time, systems theory generates terminology and conceptual frameworks that open up new and productive conversations between individual texts and the world around them, and also point to transhistorical textual affiliations that literary critics have not previously considered. The specific texts that provide the material "core" of Jaussen's argument are all examples of the long poem, a genre he proclaims a "formal misfit" within literary scholarship, as it has faced "neglect" by movements ranging from New Criticism, structuralism, and the Frankfurt School to deconstruction and even "the latest revival in critical interest in literary form" (signaled by Marjorie Levinson's 2007 PMLA essay "What is New Formalism?") (6–7). By setting up a backdrop of lyric-centric critical discourse, Jaussen presents his more targeted goal as "an attempt to respect the dynamism, the creativity, and the continued timeliness of the long poem" (37). In terms that clearly bring the book's broad and narrow goals together, he proposes that [End Page 853] "long poems persistently reflect on the challenges of transformation within time, quite often anticipating the discourse of complex adaptive systems," and that, as a result, "systems theory and the long poem may be not-so-distant cousins, sharing a family resemblance of concerns" (5). Jaussen pitches his approach as a strategy that avoids the either/or debates around historicist and formalist interpretive practice, as he is simultaneously attentive to formal structures and aware of poetry's embeddedness in its historical moment and place of origin. "In many of the poems I consider," he explains "one cannot cleanly separate formal adaptation from unexpected historical events because the poem's … form becomes the framework through which the environmental event is experienced as an event" (4; emphasis in original). Or, as he puts it in chapter two (on Whitman), he is "not proposing a formalist reading at the exclusion of historicizing or theorizing interpretations. Instead, an emergent model of form shows history, form, and theory as themselves networked, structurally coupled, and mutually illuminating" (43). The book's sustained interest in poetry's responsiveness...

Making a Modernist Masterpiece: The Elusive Location of Cultural Significance in Les Vampires

Making a Modernist Masterpiece:The Elusive Location of Cultural Significance in Les Vampires Hervé Picherit (bio) This article begins with an apparently simple question: is it possible to watch Louis Feuillade's serial masterpiece Les Vampires (1915–16) as it was originally shown—as the future surrealists André Breton and Louis Aragon would have seen it?1 Can we access the episodic unfolding, between 1915 and 1916, of the journalist Philippe Guérande's efforts to investigate and to thwart the machinations of Irma Vep and the criminal Vampire gang? Indeed, though fully restored, this film cannot hide the repeated alterations to which it was subject. And though critics have observed that war deeply inflects the images and themes of Les Vampires—the serial containing representations of poison gas, artillery bombardment, and espionage—the film's capacity to tell us about the time and place of its production seems all the more tenuous, given that close readings reveal evidence of the film's shifting and indeterminate nature.2 The elements of Les Vampires we might try to trace back to the original moment of the film's creation open instead on a multiplicity of mediated versions. Perhaps most unsettlingly, this interpretive uncertainty is different from the indeterminacy characterizing other modernist projects—for example, readings of Virginia Woolf's Mrs Dalloway. Unlike Woolf's novel, Feuillade's film belonged to a nascent medium whose cultural, social, aesthetic, and economic codes were rooted in nimbleness and variability. While contemporary categories such as literature, the novel, and single-author fiction represented stabilizing forces in Mrs Dalloway then, we cannot assume as much about cinema, film serials, or directorial [End Page 655] authority—categories which remained largely in flux at the time of Les Vampires, and have since evolved dramatically. This is a distinction that calls to mind Jorge Luis Borges's short story "Pierre Menard, Author of the Quixote." Juxtaposing Menard's word-for-word reprisal of Cervantes's novel with the original, an imaginary critic concludes that the former's style is archaic and affected, while the latter "handles with ease the current Spanish of his time."3 Similarly, we might observe that the movie Breton and Aragon watched in 1915 and 1916 is a temporary commodity designed only to last as long as it could make—and that Vampires is a story conveyed by a fragmented, varied, and ephemeral medium whose narrative structures and visual form both functioned, by design, according to a form of textual variability. The movie we watch, on the other hand, is a modernist masterpiece whose breaks with cinematic convention bear the hallmarks of avant-garde experimentation; it is a "found film" whose preservation and stabilization helped define a unique form of cinephilic viewership that recognizes priceless artifacts in examples of early film. Far from being simple, then, the question of this wartime serial's relationship with the context of its production forces us to reexamine the scope of Les Vampires's interpretable meaning, as well as the cultural location of this cinematic work's artistic significance. It is a task we can begin by defining the indeterminacy specific, if not to Les Vampires, then to similar examples of early cinema. Films like Feuillade's were subject to a material and cultural fragmentation that requires—and has always required—a unique relationship between the film and its reception. Indeed, though interpretations of Woolf's novel have changed through time, few, if any, of these readings have directly altered the textual artifact itself. This is not the case of Les Vampires, a work for which successive acts of reception have frequently implied distinct acts of (re)creation. Whether it was in response to the literal fragmentation of the film stock that had to be pieced together by each projectionist in 1915 and 1916, or to the historical and cultural fragmentation that has led to past and current restoration projects, Les Vampires has remained subject to mediating forces seeking to "make sense" of the film before showing it to the public. It is the evolution of these acts of "making sense," over the past hundred years, that has produced a network of Vampires versions, each reflective of a particular...

Thomas Belling, Antike Grabstörungen auf dem frühmittelalterlichen Gräberfeld Köln-Müngersdorf / Ancient Grave Manipulation at the Early Medieval Burial Site Köln-Müngersdorf

Ancient grave manipulations have been recorded continuously on early medieval burial sites. The Franconian necropolis Köln-Müngersdorf is no exception to the phenomenon. Already in 1955 Fritz Fremersdorf mentioned the manipulations in his publication, yet without widespread interpretation. This resulted in the opportunity to round the researches in Köln-Müngersdorf for another interesting aspect. The grave manipulations have been analyzed in detail for several aspects: burial depth, furniture, gender distribution, et cetera. In result, they were visualized in schemata as well as maps and afterwards interpreted by them. The aim of the research was, to attain information about the moment of manipulation, motivations and origin of the manipulants and what have been token from the burial equipment. Furthermore, if it is possible to obtain those information from the archaeological feature. The presented essay is an extraction from the authors graduation work to attain the Bachelor of Arts.

Experimental investigations on monotonic and cyclic behavior of steel pallet rack connections

Abstract Application of steel pallet racks (SPRs) for storage purposes has been widely grown around the world since the age of the industrial revolution. SPRs are cold formed structures and beam-to-column connections (BCCs) used in these structures are largely responsible for the sway stability of these frames in the down-aisle direction. It is essential to understand the performance of SPR BCCs under variable circumstances. This study investigates the monotonic and cyclic behavior of SPR BCCs. The cantilever test method was used and six monotonic and six cyclic tests were conducted according to the European standard and major failure modes and moment-rotation (M-θ) behavior of the connections were identified. In order to appraise the influence of parameters, the connections were distinguished by column thickness. After investigating the original rotational stiffness value, moment resistance, ductility and failure mode of the connection, an innovative design of SPR BCC is proposed with one additional bolt in the beam end connector and monotonic testing was performed. The findings showed that the proposed connections increased the performance of SPR BCC to a larger extent.

Antiferromagnetic order in hybrid electromagnetic metamaterials

We demonstrate experimentally a new type of order in optical magnetism resembling the staggered structure of spins in antiferromagnetic ordered materials. We study hybrid electromagnetic metasurfaces created by assembling hybrid meta-atoms formed by metallic split-ring resonators and dielectric particles with a high refractive index, both supporting optically-induced magnetic dipole resonances of different origin. Each pair (or ‘metamolecule’) is characterized by two interacting magnetic dipole moments with the distance-dependent magnetization resembling the spin exchange interaction in magnetic materials. By directly mapping the structure of the electromagnetic fields, we demonstrate experimentally that strong coupling between the optically-induced magnetic moments of different origin can flip the magnetisation orientation in a metamolecule creating an antiferromagnetic lattice of staggered optically-induced magnetic moments in hybrid metasurfaces.

The Point of No Return: Wendy Nanan as Postindenture Indian Female Visionary Artist

This essay examines the organic connection between the methods and materials used by Indian artist Wendy Nanan and the metaphysical ideas that underpin her creativity. Her exposure to a mixture of religious and cultural practices drawn from Presbyterianism and Hinduism, to the variegated festivals of a postslavery postindenture society of Trinidad is re-presented in the symbolic and allegorical pieces that Nanan has produced for over two decades. These evoke messages of harmony despite difference and of political agency for a nation. Her symbolism establishes an Indian aesthetic and iconography that has evolved in this society beyond its original moment of entry to a point of no return to an imagined purity.

A vine-copula-function-based structural uncertainty propagation analysis method

Most of the existing uncertainty propagation analysis methods assume that the input variables are independent of each other. However, in practical engineering, there are a lot of correlations among variables. In order to solve this problem, this paper proposes a vine copula based structural uncertainty propagation analysis method which is an effective approach for performing an uncertainty propagation analysis on complex multidimensional correlation problems. First, a joint probability distribution function (PDF) among multidimensional input random variables is established using a vine copula function. Second, correlated variables are transferred to independent variables by Rosenblatt transformation and the first four original moments of the response are calculated by dimension reduction integration method. Third, PDF of response is calculated by maximum entropy principle. Three numerical examples indicate that this method produces small discrepancy compared with Monte Carlo Simulation and is satisfactory respect to computation accuracy and efficiency. This method can be used to analyze the uncertainty propagation of complex engineering problems with complex correlations.

基于改进Hu不变矩和SVM的转子故障诊断方法

在转子发生故障时，对转子进行准确地故障诊断一直是工程领域研究的重点。针对这一问题，本文提出了一种基于改进Hu不变矩和支持向量机(SVM)相结合的转子多故障诊断方法。该方法首先通过仿真合成4种常见故障的轴心轨迹图，并利用改进Hu不变矩分别对其进行特征提取，然后将得到的Hu不变矩值作为特征向量输入有向无环图SVM进行识别分类，最终实现转子的多故障诊断。经实验表明，该方法能够准确地完成转子的多故障诊断，同时通过与原始Hu不变矩比较，证明改进Hu不变矩在识别准确率上明显优于原始Hu不变矩。 The accurate diagnosis of fault conditions of steam rotor when faults occur in rotor has been the re-search focus in the field of engineering. To solve this problem, this study proposes a multiple fault diagnosis method for steam rotor based on the improved Hu invariant moments and SVM. First, 4 kinds of common faults’ Shaft orbits are synthesized by simulation in this method, and extract fea-tures by the improved Hu invariant moments, then, the Hu invariant moment values will input to the directed acyclic graph SVM as feature vectors to recognize and classify, and ultimately achieve the multiple fault diagnosis of rotor. The experimental results show that this method can accurately complete rotor multiple fault diagnosis. Meanwhile, to compared with the original Hu invariant moments, it is proved that the improved Hu invariant moments are better than the original Hu in-variant moments in the recognition accuracy.

Full Height Rectangular Opening Castellated Steel Beam Partially Encased in Reinforced Mortar

This paper discusses analysis and test results of full height rectangular opening castellated steel beams without encasing and with partially encasing using reinforced mortar. Each contains two types of beam span namely short span beams to study the shear failure mechanism and long span beams to study the flexural failure mechanism. Test results show that the beams without encasing have lower load capacity than the original section due to Vierendeel truss mechanism. On the other hand the application of partially reinforced mortar encasing in the long span beam can avoid the Vierendeel truss mechanism and increases the yield moment capacity around 3.5 times of original steel section yield moment. However the short span one failed in brittle shear mechanism due to diagonal crushing in the mortar and then followed by Vierendeel truss mechanism so that the flexural strength could not be achieved. Shear strength of the full height rectangular opening castellated steel beam partially encased in reinforced mortar is larger than the calculated conventional reinforced concrete shear capacity but is less than the steel web shear capacity. It is recommended that the shear strength is calculated using diagonal strut mechanism of the mortar to give more appropriate shear strength prediction.

The Restored Literary Behaviors of Neo-Slave Narratives: Troubling the Ethics of Witnessing in the Excessive Present

The Restored Literary Behaviors of Neo-Slave NarrativesTroubling the Ethics of Witnessing in the Excessive Present Jesse A. Goldberg (bio) Reader, be assured this narrative is no fiction. —Harriet Jacobs, Incidents in the Life of a Slave Girl When I'm telling you something don't you ever ask if I'm lying. Because they didn't want to leave no evidence of what they done—so it couldn't be used against them. And I'm leaving evidence. And you got to leave evidence too. And you children got to leave evidence. And when it come time to hold up the evidence, we got to have evidence to hold up. —Gayl Jones, Corregidora Early in Gayl Jones's 1975 novel Corregidora, the protagonist Ursa remembers her Great Gram's charge to her descendants, a charge which is instructional for reading the neo-slave narrative genre. Great Gram signifies on the convention by which antebellum slave narratives' authors (and those who wrote their paratextual authenticating documents) had to (re)assert throughout their writing that they were not lying. Such (re)assertions both reinscribed and sought to defy the charge that the enslaved subject could not be trusted to bear witness to truth, whether in a court of law or otherwise.1 Great Gram's slap and assertion trans/re-figures Harriet Jacobs's (et al.) insistence on veracity from a plea for readers' sympathy and trust to an attempt to, as Christina Sharpe emphasizes, "make redress to the law itself" (Monstrous Intimacies 40). Insofar as Great Gram's slap and assertion both repeat and revise the antebellum slave narrative's insistence on truth and call forward in time to a deferred moment of future justice, they illustrate a model for what I call restored literary behaviors. Restored literary behaviors trouble the linear temporality and "social logic" of rupture which are implicitly present in the neo in the phrase neo-slave narrative and explicitly appealed to in Ashraf Rushdy's insistence on figuring the Black Power movement not only as a moment of inspiration, but as a moment of "origin" for the form itself in his seminal 1999 book, Neo-Slave Narratives: Studies in the Social Logic of a Literary Form. Rather than reading neo-slave narratives as encompassing a genre with a defined moment of origin, as Rushdy does, I argue through a close reading of Sherley Anne Williams's 1986 novel Dessa Rose and Toni Morrison's 2008 novel A Mercy that neo-slave narratives embed the past, present, and future together in an "excessive present" within their texts and thus enact both [End Page 57] continuity and rupture through literary acts which reach back in time in order to call into the future through engaging with and making demands on the immediately present readers to bear the burden of witnessing. And then, given the familiarity of the invocation of "witnessing" as an ethical demand in African Americanist literary studies, I also, through Fred D'Aguiar's 1997 novel Feeding the Ghosts, gesture towards the limits of witnessing as an end in itself, such that "making demands" in this sense denotes witnessing as a means, not an end, of ethics. In other words, witnessing is not the point, but rather the actions that follow from witnessing are. Of course, the notion of texts making demands on their own readers is a signal attribute of the nineteenth-century slave narrative. While the specific techniques used by authors of slave narratives vary too much to suggest uniformity in mode of appeal, it is clear that slave narratives were aimed towards abolition and therefore explicitly addressed readers through the use of second-person interpellation, thus creating a dialogue between narrator and reader. To use Toni Morrison's words: "Whatever the style and circumstances of the narratives, they were written to say principally two things. One: 'This is my historical life—my singular, special example that is personal, but that also represents the race.' Two: 'I write this text to persuade other people—you, the reader, who is probably not black—that we are human beings worthy of God's grace and the immediate abandonment of slavery'" ("The Site of Memory" 66...

Even Laughter? From Laughter in the Magic Theater to the Laughter Assembly Line

Local magnitude estimation in Greece, based on recordings of the Hellenic Unified Seismic Network (HUSN).

A new relation is proposed for calculation of local magnitudes in Greece. For this purpose, there were used synthetic Wood-Anderson (SWA) recordings of 98 digital broad-band stations operating between 2007 and 2011. These stations are installed at the sites of the seismological networks of: a) the National Observatory of Athens(HL), b) the Department of Geophysics of the Aristotle University of Thessaloniki (HT), c) the Seismological Laboratory of the University of Athens (HA) and d) the Seismological Laboratory of the University of Patras (HP). All these institutions constitute the recently (2004) established Hellenic Unified Seismic Network (HUSN). These recordings are used to calculate a refined geometrical spreading factor and an anelastic attenuation coefficient, representative for Greece and surrounding area, proper for estimating local magnitudes in this region. Individual station corrections are also calculated in order to further ameliorate magnitude estimation accuracy. Comparison of such calculated local magnitudes with corresponding original moment magnitudes revealed that these two scales are equivalent for awide range of values (2.9≤MW≤6.4).

Soft Measurement of the Purity of the Synthetic Edible Pigment Powder Using Fluorescence Spectroscopy Combined with SVM

The feature compression algorithm which was reformed from the original Moment method was used for the pre-processing of the fluorescence spectral data, then combined the data and the Weighted Least Squares Support Vector Machine(WLS-SVM) algorithm to establish a robust regression model, which is used for forecasting the purity of edible pigment powder. In this paper, brilliant blue and ponceau 4R served as an example to discuss the method of forecasting effect of edible pigment powder purity. The emission fluorescence spectra of two edible pigment at the optimal excitation wavelength were measured by FLS920 fluorescence spectrometer. The compression and transformation of the fluorescence spectral data was acquired by the feature compression algorithm reformed from the Original Moment method. On the one hand the feature compression algorithm shortened the operation time, on the other hand it improved the prediction accuracy of the model. Then, the concentration prediction model was established after inputting the fluorescence spectral data pre-processed into the Weighted Least Squares Support Vector Machine. The model gave anastomotic predicted spectral data with the actual experiments of the brilliant blue and ponceau 4R, and the average coefficient of determination in the half peak width was 0.700 and 0.930 respectively. There was a good linear relationship between the predicted and the nominal concentration of the brilliant blue and ponceau 4R, and the correlation coefficients were 0.997 and 0.992 respectively. It can be concluded that, the predicted concentration of the brilliant blue and ponceau 4R powder were got the results of 61.0% and 72.3% respectively.

Competitive moment matching of a New-Keynesian and an Old-Keynesian model

The paper considers two rival models referring to the new macroeconomic consensus: a standard three-equation model of the New-Keynesian variety versus dynamic adjustments of a business and an inflation climate in an ‘Old-Keynesian’ tradition. Over the two subperiods of the Great Inflation and Great Moderation, both of them are estimated by the method of simulated moments. An innovative feature is here that the moments do not only include the autocovariances up to eight lags of quarterly output, inflation and the interest rate, but optionally also a measure of the raggedness of the three variables. In short, the performance of the Old-Keynesian model is very satisfactory and similar to the New-Keynesian model, or even better. In particular, the Old-Keynesian model is better suited to match the new moments without deteriorating the original second moments too much.

Epidemic spreading in random walkers with heterogeneous interaction radius

We study epidemic spreading in a random walk network where agents with heterogeneous interaction radius randomly walk in a planar space. We obtain the explicit expression of epidemic threshold which indicates that the heterogeneity of interaction radius decreases the threshold. Concretely, the greater the variance of the radius distribution is, the smaller the epidemic threshold will be. Simulation results about the epidemic threshold match well with our theoretical results. In simulation study, the infection density in steady state, which is called the final density, is investigated. When there are two different values of radius, a larger mean value of radius increases the final density. However, although an increasing second order origin moment of radius makes the epidemic easier to outbreak, it also lowers the final density of infected individuals.

Baseline γH2AX foci, 53BP1 values and late morbidity after definitive radio-chemotherapy in head and neck carcinoma patients

Purpose: Can double strand breaks in peripheral lymphocytes measured as baseline γH2AX and 53BP1 values be used as a signal for reduced DNA repair capacity and an increased late radiation morbidity? Methods and materials: Of 357 patients, homogenously treated with a definitive radio-chemotherapy, 11 patients without any relevant comorbidity concerning baseline DNA double strand breaks, a follow up of more than 3.5 years and different levels of late morbidity were selected. γH2AX and 53BP1 foci were analyzed, using the fully automated AKLIDES ® system (Medipan). For foci detection, images of different z-planes throughout the nucleus were obtained. For further evaluation mean focus number/cell as well as percentage of γH2AX/ 53BP1 focus-positive cells were used. Results: Patients with late toxicity levels 0°, I° and III° showed median numbers of γH2AX foci per peripheral mononuclear cell of 0.26, 0.34 and 0.73 respectively. The corresponding median values of 53BP1 foci per cell were 0.13, 0.06 and 0.40, respectively and concordant percentages of γH2AX positive cells for the 3 different late toxicity groups were 10.85, 14.30 and 30.67 as well as of 53BP1 positive cells 8.5, 5.7 and 25.37, respectively. Despite the wide interindividual range of all values, patients with severe late morbidity showed increased values for γH2AX as well as 53BP1 foci compared to the other groups, whereas no differences between groups with no or mild toxicity were seen. Conclusions: The determination of baseline γH2AX foci in peripheral blood mononuclear cells could be suited as a marker for late morbidity after definitive radio-chemotherapy of head and neck carcinoma. Blood sampling at the time of treatment i.e. moment of origin of the late effect should be more effective rather than a retrospective study. To address this question a prospective trial with a larger cohort of patients and a long term follow up is needed.

‘I have met with you, bird, too late, or if not, too worm and early’: The Eternal Circling of Yeats and Joyce

In Finnegans Wake, Joyce recasts, several times over, the central affirmation that he is credited with having made to William Butler Yeats during their much mythologised early encounter: “I have met you too late. You are too old.” These words, or a version of them, have framed studies of the Joyce-Yeats relationship which is thereafter construed as endlessly antagonistic, irretrievably oppositional. This essay will seek to challenge those readings which turn a complex relationship into Irish modernism. Critics have seen the encounter between Yeats and Joyce as an “auspicious meeting” as “an original moment, a primal scene of the modernism which both writers were subsequently to play a part in creating.” Their complex relationship can be seen against the ever widening backdrop of the Irish Literary Revival which took place in the tumultuous thirty-year period between 1891 and 1922 as well as in the context of the tension arising from the Romantic pull of the past and the inexorable draw of Modernism. In this context, Yeats and Joyce were seen as having almost entirely separate agendas, visions, and styles, and as irreconcilable antagonists, although both writers contributed, to underlining the differences and gaps rather than the connections between them. Joyce may well have met Yeats too late to deeply influence him but it might also be suggested that Yeats met Joyce too early to really be able to substantially help him.

Strain-dependent electronic and magnetic of Co-doped monolayer of WSe2

We perform first-principles calculation to investigate electronic and magnetic properties of Co-doped WSe2 monolayer with strains from −10% to 10%. We find that Co can induce magnetic moment about 0.894μB, the Co-doped WSe2 monolayer is a magnetic semiconductor material without strain. The doped system shows half-metallic properties under tensile strain, and the largest half-metal gap is 0.147eV at 8% strain. The magnetic moment (0.894μB) increases slightly from 0% to 6%, and jumps into about 3μB at 8% and 10%, which presents high-spin state configurations. When we applied compressive strain, the doped system shows a half-metallic feature at −2% strain, and the magnetic moment jumps into 1.623μB at −4% strain, almost two times as the original moment 0.894μB at 0% strain. The magnetic moment vanishes at −7% strain. The Co-doped WSe2 can endure strain from −6% to 10%. Strain changes the redistribution of charges and magnetic moment. Our calculation results show that the Co-doped WSe2 monolayer can transform from magnetic semiconductor to half-metallic material under strain.
