Radio Planetary Nebulae in the Small Magellanic Cloud
We present ten new radio continuum (RC) detections at catalogued planetary
nebula (PN) positions in the Small Magellanic Cloud (SMC): SMPS6, LIN 41, LIN
142, SMP S13, SMP S14, SMP S16, J18, SMP S18, SMP S19 and SMP S22.
Additionally, six SMC radio PNe previously detected, LIN 45, SMP S11, SMPS17,
LIN321, LIN339 and SMPS24 are also investigated (re-observed) here making up a
population of 16 radio detections of catalogued PNe in the SMC. These 16 radio
detections represent ~15 % of the total catalogued PN population in the SMC. We
show that six of these objects have characteristics that suggest that they are
PN mimics: LIN 41, LIN 45, SMP S11, LIN 142, LIN 321 and LIN 339. We also
present our results for the surface brightness - PN radius relation
({\Sigma}-D) of the SMC radio PN population. These are consistent with previous
SMC and LMC PN measurements of the ({\Sigma}-D) relation.Comment: Accepted for publication in Astrophysics and Space Scienc
Supersymmetric Extension of Hopf Maps: N=4 sigma-models and the S^3 -> S^2 Fibration
We discuss four off-shell N=4 D=1 supersymmetry transformations, their
associated one-dimensional sigma-models and their mutual relations. They are
given by I) the (4,4)_{lin} linear supermultiplet (supersymmetric extension of
R^4), II) the (3,4,1)_{lin} linear supermultiplet (supersymmetric extension of
R^3), III) the (3,4,1)_{nl} non-linear supermultiplet living on S^3 and IV) the
(2,4,2)_{nl} non-linear supermultiplet living on S^2. The I -> II map is the
supersymmetric extension of the R^4 -> R^3 bilinear map, while the II -> IV map
is the supersymmetric extension of the S^3 -> S^2 first Hopf fibration. The
restrictions on the S^3, S^2 spheres are expressed in terms of the
stereographic projections. The non-linear supermultiplets, whose
supertransformations are local differential polynomials, are not equivalent to
the linear supermultiplets with the same field content. The sigma-models are
determined in terms of an unconstrained prepotential of the target coordinates.
The Uniformization Problem requires solving an inverse problem for the
prepotential. The basic features of the supersymmetric extension of the second
and third Hopf maps are briefly sketched. Finally, the Schur's lemma (i.e. the
real, complex or quaternionic property) is extended to all minimal linear
supermultiplets up to N<=8.Comment: 24 page
'My Father’s Daughter': Filial Dislocation in Shirley Geok-lin Lim’s Poetry
Drawing on the father figure and the father–daughter dynamic in Shirley Geok-lin Lim’s poetry, this article examines how the motif of filial dislocation underlines ambivalent and complicated emotions and meanings that can be traced back to the poet’s traumatic childhood experience of her father’s violence. This experience, described here as one of acute psychical and emotional rupture and dislocation, has been imprinted onto Lim’s body and consciousness in the form of embodied memories and emotions, and reenacted in writing and poetic articulation where the father figure is concerned. Through the recurring themes of memory, (dis)connection, distance, and dislocation, Lim’s deeply personal, even autobiographical, poems explore the wounded father–daughter relationship; in so doing, they trouble the ideological premise of filial piety as a cultural concept, which upholds the child’s obligation to the parent through the performance of filial care, respect, and obedience. At the same time, Lim’s poems reflect how embodied memories and emotions are relived and refelt in the process of writing as well as the depth of the poet’s emotional response and subjective interiority in the articulation and performance of filial and gender identity. Weaving through and traversing interior and exterior spaces and landscapes of memory and imagination, body and geography, the poems illuminate complex psychological, emotional, and embodied dimensions of Lim’s mediation of her filial and gender identity as a feminist poet, a daughter, and a gendered individual
Note on W3 Realizations of the Bosonic String
In order to investigate to what extent string theories are different vacua of
a general string theory (the ``universal string"), we discuss realizations of
the bosonic string as particular background of certain types of -strings.
Our discussions include linearized , non-critical , linearized
and critical realizations of the bosonic string.Comment: 9 pages, Late
New Congruences Modulo 2, 4, and 8 for the Number of Tagged Parts Over the Partitions with Designated Summands
Recently, Lin introduced two new partition functions PD and
PDO, which count the total number of tagged parts over all partitions of
with designated summands and the total number of tagged parts over all
partitions of with designated summands in which all parts are odd. Lin also
proved some congruences modulo 3 and 9 for PD and PDO, and
conjectured some congruences modulo 8. Very recently, Adansie, Chern, and Xia
found two new infinite families of congruences modulo 9 for PD. In this
paper, we prove the congruences modulo 8 conjectured by Lin and also find many
new congruences and infinite families of congruences modulo some small powers
of 2.Comment: 19 page

'cultivated, / Wild, exotic': Nationalism and Internationalism in the Poetry of Shirley Geok-lin Lim
Born in multicultural Malacca during British rule, educated there and later in Kuala Lumpur and Boston, a long-time resident of the USA and a visiting professor to many countries, Shirley Geok-lin Lim seems a transnational writer par excellence. Yet much of her later work involves looking back to Malacca, “at a loss here, / Loosening my grip on yesterday,” afraid of losing “[s]hades of father and mother.” She is the author of poems, short stories, novels and a memoir, as well as literary and social criticism. The memoir, Among the White Moon Faces, is subtitled, “An Asian-American Memoir of Homelands,” and the plural noun is notable. Concentrating on her poetry, this paper charts her shifting sense of identity as Malaccan, Malaysian, American and as a woman of Chinese heritage whose language is English, through “[s]peech which is sufficient enterprise,” even though in these late poems she can feel “unmoored” and sense “the gravity / of the unmade I.
