Autoimmune encephalitis is increasingly recognized as a neurologic cause of acute mental status changes with similar prevalence to infectious encephalitis. Despite rising awareness, approaches to diagnosis remain inconsistent and evidence for optimal treatment is limited. The following Canadian guidelines represent a consensus and evidence (where available) based approach to both the diagnosis and treatment of adult patients with autoimmune encephalitis. The guidelines were developed using a modified RAND process and included input from specialists in autoimmune neurology, neuropsychiatry and infectious diseases. These guidelines are targeted at front line clinicians and were created to provide a pragmatic and practical approach to managing such patients in the acute setting.

The mutability of Philokleon's generational identity in Aristophanes’ Wasps is well established. Critics routinely write of his ‘rejuvenation’ in the second half of the play, and it is in the scene with the αὐλητρίϲ (‘aulos-girl’), Dardanis, that the old man most explicitly plays the part of an irresponsible youth waiting for his son (in the role of father) to die. However, inversions and perversions of generational identity pervade the whole play. Even before Philokleon has undergone his liberating transformation at the symposion, the educational roles of father and son are reversed as Bdelykleon schools him in the proper way to behave in polite society. More subtly and extensively, Bowie has shown how the three agones in which Philokleon unsuccessfully engages during the first half of the play correspond to the three stages of an Athenian male citizen's life: ephebeia, maturity in the hoplite phalanx, and old age in the jury. However, critics have not observed that Philokleon goes through another, parallel journey from youth through maturity to old age in the three ‘iambic scenes’ where he is confronted by the victims of his outrageous behaviour on his way home from the symposion. This article will show how Aristophanes constructs this third lifecycle (counting Bowie's agones and his literal maturation before the play's action begins) before considering its implications for the wider characterization of Philokleon and in particular the final scene.

In Aristophanes’ Wasps, Philocleon says that he and his fellow jurors do not acquit Oeagrus until he has recited a speech from the Niobe. Scholars have almost universally assumed that this was the name of a contemporary tragic actor, despite its extreme rarity. This article argues that the reference is rather to the father of Orpheus. As a figure from the generation before the archetypal bard, ‘an Oeagrus’ represents the old-fashioned poetry to which Philocleon and his fellow jurors are devoted.

Carmen 108 is one of the most neglected and unloved in the Catullan corpus. When it is mentioned in scholarship, it is either as a distastefully extreme instance of iambic invective or the object of a prosopographical exercise in identifying the addressee, Cominius. Gnilka alone has tried to situate it in the context of late Republican political violence, in particularly public lynching. Instead of isolating these two aspects of the poem from each other, this article argues that c. 108 is a self-conscious exploration of the interaction between poetic form and hors-texte. The terms of the invective situate it firmly within the tradition of Archilochean and Hipponactean iambos and it may even allude directly to a fragment of the latter. Yet the threats of violence are transformed when recontextualized within the world of the late Republic, where such literary violence was very much a reality. The poem performs a symbolic dismemberment of Cominius’ body, but one that cannot be safely separated from acts of mob violence in the period. The pragmatics of Catullan iambos explores the limits of verbal violence as speech-act and the point at which hate-speech becomes indistinguishable from the violence it incites.

Virgil's list of the qualities that are desirable in a brood cow corresponds closely to those in Varro's De re rustica and in the texts which, though later, can be plausibly taken as evidence of an existing tradition. Yet, there is one exception, and it is an exception to which the poet carefully draws attention. Varro's, Columella's and Palladius’ ideal cows all share with Virgil's and with each other hairy ears, very long dewlaps and tail, and other features. However, whereas they all have narrow hooves (ungulis breuibus, Palladius), moderate at most (ungulis modicis, Columella), and certainly not broad (pedibus non latis, Varro), Virgil's cow emphatically has big feet (Verg. G. 3.51–9):

optima toruae
forma bouis cui turpe caput, cui plurima ceruix,
et crurum tenus a mento palearia pendent;
tum longo nullus lateri modus: omnia magna,
pes etiam, et camuris hirtae sub cornibus aures. 55
nec mihi displiceat maculis insignis et albo,
aut iuga detrectans interdumque aspera cornu
et faciem tauro propior, quaeque ardua tota
et gradiens ima uerrit uestigia cauda.

The best shape
for a fierce cow is one which has an ugly head, which has a lot of neck
and whose dewlaps hang from her chin all the way down to her legs;
then let there be no limit to the length of her flank: let everything be big,
even the foot, and hairy ears under in-curving horns,
and I would approve of her being marked with white spots,
either refusing the yoke or sometimes fierce with her horn
and in appearance closer to a bull, and who is lofty in every respect
and when walking sweeps her tracks with the tip of her tail.

This paper provides an up-to-date review of the problems related to the generation, detection and mitigation of strong electromagnetic pulses created in the interaction of high-power, high-energy laser pulses with different types of solid targets. It includes new experimental data obtained independently at several international laboratories. The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produce. The major emphasis is put on the GHz frequency domain, which is the most damaging for electronics and may have important applications. The physics of electromagnetic emissions in other spectral domains, in particular THz and MHz, is also discussed. The theoretical models and numerical simulations are compared with the results of experimental measurements, with special attention to the methodology of measurements and complementary diagnostics. Understanding the underlying physical processes is the basis for developing techniques to mitigate the electromagnetic threat and to harness electromagnetic emissions, which may have promising applications.

Epistemic Perceptualists claim that emotions are sources of immediate defeasible justification for evaluative propositions that can (and do) sometimes ground undefeated immediately justified evaluative beliefs. For example, fear can constitute the justificatory ground for a belief that some object or event is dangerous. Despite its attractiveness, the view is apparently vulnerable to several objections. In this paper, I provide a limited defence of Epistemic Perceptualism by responding to a family of objections which all take as a premise a popular and attractive view in value theory – Neo-Sentimentalism – according to which values are analysed in terms of fitting emotions.

Poet-figures in Ovid's Metamorphoses have been the object of much study, especially those silenced by the powerful, but little attention has been given to Pyreneus. Immediately before the famous contest of the Muses and Pierides, the former briefly narrate their attempted rape by the usurping Thracian tyrant Pyreneus and his precipitous death while trying to fly after them. The few critics who have touched on this episode have tended to focus exclusively on one aspect, be it the poetic, sexual, political, or religious. None has provided a holistic interpretation which does justice to the complex interplay of these four dimensions or to Ovid's witty and characteristic reification of figurative language.

Pyreneus is simultaneously an invading usurper, an attempted rapist, an impious theomach, and, on the poetic plane, a talentless plagiarist or derivative imitator, who tries to appropriate others’ work but bathetically and disastrously fails. The interrelation of these four roles, each troping the others, throws light on all, and Pyreneus needs to be contextualized among the Met.'s other tyrants, rapists, and theomachs, as well as its poet-figures. The episode itself, derivative and overstuffed with Ovidian motifs, is mimetic of the sort of narrative bad (would-be) poets like Pyreneus produce.

Among the personal hobbies which Horace recommends his young friend Lollius conduct at a discreet distance from his potens amicus is the re-enactment of the battle of Actium, which should only be undertaken in the privacy of his father’s estate. Critics have noted that the potential offence in this seemingly affirmative celebration of the ‘miracle of Actium’ lies in the casting of Lollius’ brother as his opponent, thus acknowledging the civil nature of the battle which was at least downplayed, if not elided, in official discourse. They have overlooked, however, the further subversive element in Horace’s reference to ‘whichever of the two (alterutrum)’ Victory crowns. This presents the counterfactual possibility, both in the Epistle and in the naumachia which serves as a parallel mimesis, that Antony might have won the battle of Actium. This instance of ‘sideshadowing’ demands to be set in a number of contexts, such as the use of counterfactuals in historiographical depictions of battles and the phenomenon whereby some public naumachiae had outcomes contrary to that of the historical battle they were re-enacting. In particular, the very possibility of an Antonian victory renders the Augustan principate contingent, in opposition to the providential, teleological inevitability with which it, and especially its foundational battle, were depicted elsewhere in Augustan poetry. Such an interpretation is supported by Lucan’s allusion to this passage in his Dyrrachium episode, the only other non-Lucretian instance of alterutrum in extant Latin poetry.

If satire is epic's ‘evil twin’, then tragedy is satire's ugly sister. Both epic and tragedy soar aloft in the stratosphere of the generic hierarchy, viewed humbly and from a distance by satire's pedestrian muse, who at the same time scoffs at their overblown irrelevance. Many of the same criticisms, often framed as back-handed compliments, are cast at both genres by their poor relation, but there are also distinctions. Epic, even if cloistered in an ivory tower, is constructed as sharing the impossible purity of that ivory, the better for its lofty and noble themes to be befouled, debased and perverted in the distorting mirror held up by its evil twin. Tragedy, however, is itself a perversion, ethically and aesthetically, a mishmash of vice and excess which is a natural target for satire, the self-appointed social policeman, but which also bears an uncomfortable resemblance to satire's own nature. Much work has been done in recent years on satire's engagement with and tendentious construction of tragedy, but very little on tragedy's reciprocal engagement with satire. The latter will be the focus of this article, approached from two, closely-related angles.

Ovid, Metamorphoses 8.18, in which Scylla throws a tiny pebble against Megara's famous sounding tower, contains an exact, unique but unnoticed verbal echo of Helenus' description of the sea-monster Scylla's lair at Aeneid 3.432: resonantia saxa. The allusion tropes its own intertextual status as an ‘echo’ and contributes to the ludic confusion of the two Scyllas in this episode and elsewhere. The collision of the ‘tiny pebble’ with the Virgilian rocks further tropes the episode's elegiac and Callimachean recasting of epic material. The childishness of the game is also part of the self-conscious puerility of the Metamorphoses' poetics.

The primary obscenity futuo (‘the male part in sexual intercourse with a woman’) is unsurprisingly rare in literary Latin. Apart from a single occurrence in Horace's Satires (1.2.127, in a passage evoking the adultery mime), its usage is limited to the even lower genre of scoptic epigram, as represented by Catullus, Octavian, Martial and the Priapeia, though it frequently occurs in graffiti. Adams has shown how it tends to be a neutral and even affectionate term, lacking any sense of aggression, though not of the assertion of conventional virility. Nevertheless, it is used almost exclusively of recreational, extramarital and/or illicit sex. This may be in part a function of the way in which its obscenity and low linguistic register (closely equivalent to its English equivalent ‘fuck’) restrict it to the low genres which tend to deal with such subject matter, but this is a potentially circular argument and, whether chicken or egg came first, the undeniable result is an association of the verb with intercourse which is not primarily or even in any way aimed at procreation. It is striking and anomalous, therefore, when Martial uses futuo, on five occasions, in contexts relating to the production (or avoidance of the production) of children. Of course, on a purely logical and biological level, the connection between futuo (specifically the penetration of the vagina by the penis, carefully differentiated by Martial in particular from sexual practices involving other orifices and/or members, such as pedicatio, fellatio and cunnilingus) and the engendering of children is an obvious one. Nevertheless, the aforementioned strong associations of the verb with sex aimed at everything but procreation renders its use in this context jarring. This incongruity and clash of registers is, of course, characteristic of Martial's technique, and the obscenity gains an added spice from being applied to respectable marital relations. The jarring quality is an end in itself and accounts for itself. Yet I wish to argue that there is a further dimension to this discordant association of ‘fucking’ and ‘begetting’, based on a bilingual wordplay between futuo and its near-homonym, the Greek verb φυτεύω. By means of this pun, Martial mischievously suggests not only that ‘fucking’ can be mentioned in the context of ‘begetting’, but also that the two are—in accordance with biology but against all decorum—identical.

The conclusion of Chrysalus' famous canticum comparing the successful duping of his master Nicobulus to the sack of Troy has often been suspected by critics (Plaut. Bacch. 976–7):

nunc Priamo nostro si est quis emptor, comptionalem senem
uendam ego, uenalem quem habeo, extemplo ubi oppidum expugnauero.

Virtually nothing is known for certain about Sophokles' satyr play Salmoneus. However, a number of extremely probable deductions may be made on the basis of the few surviving fragments and the mythographic testimony about its eponymous villain (the iconographical record is totally unhelpful, or almost so). This article adds some further suggestions about the implications of the three most substantial fragments, which, if they do not quite share that level of extreme probability, it is hoped have a high degree at least of plausibility, and some significance for (meta-)dramatic and thematic aspects of the play as a whole. I shall argue that a reference to the malodorous quality of the thunderbolt draws attention to the gross physicality of the thunder-machine or bronteion (βροντεῖον) which Salmoneus has invented and constructed out of ox-hides. This has both a metatheatrical dimension, since the bronteion was probably part of the stage-machinery of 5th-century drama, and a thematic one, since it emphasises the low, corporeal nature of Salmoneus' thunder in contrast to the sublime weapon of Zeus which it imperfectly mimics. The established parallelism between thunder and farting adds another level to the debasing of Salmoneus’ invention and concomitant deflation of his pretensions. Finally, I shall suggest that another fragment relating to the sympotic game of kottabos may have drawn a similarly deflating parallel between the hurling of the wine-lees and that of the tyrant's ersatz thunderbolts.
