Chase Robinson, Islamic Civilization in Thirty Lives: The First 1,000 Years
Creators: name: Ulrich, Brian
Publisher: name: Al-ʿUsur al-Wusta
Year: 2017

description: The technique of using biography to make history accessible to newcomers is alive and well. Oneworld publishes the Makers of the Muslim World series, and Oxford University Press has The World in a Life. Textbooks often introduce chapters with an illustrative biography, such as the travelers in Valerie Hansen and Kenneth Curtis’s Voyages in World History. 1 The Islamic world also has its own tradition of ṭabaqāt and maʿājim biographical literature highlighting worthies of different fields and serving as reference material for hadith criticism. Referencing the latter tradition, but certainly in harmony with the former, Chase Robinson has used brief accounts of 30 prominent men and women to introduce readers to the first millennium of Islamic history.

Christophe Picard, La Mer des Califes: Une histoire de la Méditerranée musulmane
Creators: name: Gordon, Matthew S.
Publisher: name: Al-ʿUsur al-Wusta
Year: 2017

description: L a Mer des Califes, a challenging and erudite work, deserves a wide audience. It raises many new questions in centering the Mediterranean in early and medieval Muslim history and historiography. The sea, Christophe Picard argues, was a preoccupation of empire and the stuff of memory. A proper English translation is very much in order.1 Readers should be forewarned that, particularly for modern works, Picard’s annotation is rather spare. He furnishes citations, to be sure, but these are few relative to the wealth of his discussion; the decision is likely to have been editorial, as the volume seems intended for a broad audience. This is less a failing of an excellent book than a source of regret that one cannot more readily engage its many ideas.

description: Line-of-sight magnetograms from the Helioseismic and Magnetic Imager (HMI) of the Solar Dynamics Observatory (SDO) are analyzed using a diagnostic known as the "Magnetic Range of Influence," or MRoI. The MRoI is a measure of the length over which a photospheric magnetogram is balanced and so its application gives the user a sense of the connective length scales in the outer solar atmosphere. The MRoI maps and histograms inferred from the SDO/HMI magnetograms primarily exhibit four scales: a scale of a few megameters that can be associated with granulation, a scale of a few tens of megameters that can be associated with super-granulation, a scale of many hundreds to thousands of megameters that can be associated with coronal holes and active regions, and a hitherto unnoticed scale that ranges from 100 to 250 megameters. We infer that this final scale is an imprint of the (rotationally-driven) giant convective scale on photospheric magnetism. This scale appears in MRoI maps as well-defined, spatially distributed, concentrations that we have dubbed "g-nodes." Furthermore, using coronal observations from the Atmospheric Imaging Assembly (AIA) on SDO, we see that the vicinity of these g-nodes appears to be a preferred location for the formation of extreme ultraviolet (EUV, and likely X-Ray) brightpoints. These observations and straightforward diagnostics offer the potential of a near-real-time mapping of the Sun's largest convective scale, a scale that possibly reaches to the very bottom of the convective zone.

description: Those subject to Arab-Islamic rule are likely to have wondered at the life span of the new religio-political order at the close of the first/seventh century. The conquerors were a quarrelsome lot, as quick to engage in internecine violence as they were to subdue local opposition: the ‘believers’ were at each other’s throats. From, in part, the accounts of a then burgeoning and variegated population of clients and slaves (mawālī), it is clear that a new religious program was taking shape. But sharp disagreements over its central precepts were no less obvious; divisions of belief ran as deep as those of kinship. How long could the new masters carry on this way?

description: The ferropnictide superconductors exhibit a sensitive interplay between the lattice and magnetic degrees of freedom, including a number of phonon modes that are much softer than predicted by nonmagnetic calculations using density functional theory (DFT). However, it is not known what effect, if any, the long-range magnetic order has on phonon frequencies above 23 meV, where several phonon branches are very closely spaced in energy and it is challenging to isolate them from each other. We measured these phonons using inelastic time-of-flight neutron scattering in ~40 Brillouin zones, and developed a technique to determine their frequencies. We find this method capable of determining phonon energies to ~0.1 meV accuracy, and that the DFT calculations using the experimental structure yield qualitatively correct energies and eigenvectors. We do not find any effect of the magnetic transition on these phonons.

Peter Webb, Imagining the Arabs: Arab Identity and the Rise of Islam
Creators: name: Wood, Philip
Publisher: name: Al-ʿUsur al-Wusta
Year: 2017

description: Peter Webb’s Imagining the Arabs re-examines the relationship between the advent of Islam and the emergence of the Arabs. Turning much received wisdom on its head, he argues that there was no homogenous Arab people that lived in pre-Islamic Arabia to whom Muhammad delivered his message. Rather, he argues, Arabness was a product of a post-conquest environment, in which the conquerors emphasized language and descent as a means of excluding new converts from claiming the massive resources of the new caliphate.

description: This paper presents a solution to the Flowgraphs case study for the Transformation Tool Contest 2013 (TTC 2013). Starting from Java source code, we execute a chain of model transformations to derive a simplified model of the program, its control flow graph and its data flow graph. Finally we develop a model transformation that validates the program flow by comparing it with a set of flow specifications written in a domain specific language. The proposed solution has been implemented using ATL.

description: We propose a method for detecting many-body localization (MBL) in disordered spin systems. The method involves pulsed, coherent spin manipulations that probe the dephasing of a given spin due to its entanglement with a set of distant spins. It allows one to distinguish the MBL phase from a non-interacting localized phase and a delocalized phase. In particular, we show that for a properly chosen pulse sequence the MBL phase exhibits a characteristic power-law decay reflecting its slow growth of entanglement. We find that this power-law decay is robust with respect to thermal and disorder averaging, provide numerical simulations supporting our results, and discuss possible experimental realizations in solid-state and cold atom systems.

Conflict and Community in the Medieval Caucasus
Creators: name: Vacca, Alison M.
Publisher: name: Al-ʿUsur al-Wusta
Year: 2017

description: In the 230s/850s, the caliph al-Mutawakkil sent his general, Bughā al-Kabīr, to assert control over the wayward northern frontier of the ʿAbbāsid Caliphate. This campaign typically appears in modern scholarship as a moment that pitted Armenian Christians against tačiks (Arab Muslims). This paper complicates this binary by (1) placing T‘ovma Arcruni’s History of the Arcruni House in dialog with Arabic accounts of the campaign and (2) locating the campaign in the broader context of fragmented political power in the Caucasus as a whole. It reviews Bughā’s main allies and adversaries in the conflict with close attention to the descriptors (or lack thereof) of their identities in medieval texts. From there, it challenges the oversimplification of the campaign in ethnoreligious absolutes as Arab v. Armenian or Muslim v. Christian as a product of T‘ovma’s own agenda. This article posits the narrative use of ethnic and religious signifiers, despite the apparent flexibility of communal identities in the medieval period, and focuses specifically on the experience of women in the campaign to signal the close relations between groups of different ethnicities and religions.

description: A three-dimensional (3D) Dirac semimetal is the 3D analog of graphene whose bulk band shows a linear dispersion relation in the 3D momentum space. Since each Dirac point with four-fold degeneracy carries a zero Chern number, a Dirac semimetal can be stable only in the presence of certain crystalline symmetries. In this work, we propose a general framework to classify stable 3D Dirac semimetals. Based on symmetry analysis, we show that various types of stable 3D Dirac semimetals exist in systems having the time-reversal, inversion, and uniaxial rotational symmetries. There are two distinct classes of stable 3D Dirac semimetals. In the first class, a pair of 3D Dirac points locate on the rotation axis, away from its center. Moreover, the 3D Dirac semimetals in this class have nontrivial topological properties characterized by 2D topological invariants, such as the $Z_{2}$ invariant or the mirror Chern number. These 2D topological indices give rise to stable 2D surface Dirac cones, which can be deformed to Fermi arcs when the surface states couple to the bulk states on the Fermi level. On the other hand, the second class of Dirac SM phases possess a 3D Dirac point at a time-reversal invariant momentum (TRIM) on the rotation axis and do not have surface states in general.

The Abbasid “Golden Age”: An Excavation
Creators: name: Cooperson, Michael
Publisher: name: Al-ʿUsur al-Wusta
Year: 2017

description: The application of a Hegelian rise-and-fall narrative to the history of Arabic literature has been erroneously attributed to Ibn Khaldūn and his successors, though it can more probably be traced back to Hammer-Purgstall’s Literaturgeschichte der Araber (1850). Although this paradigm has long been out of favor, its disappearance leaves us without a ready answer to the question of what (if anything) was distinctive about what is still sometimes called the early Abbasid golden age. The prominence of this era in later memory is here traced to the adoption of paper, which supported, on the one hand, the simplification and vulgarization of Arab language, lore, and religion; and on the other, the appearance of the first reliably contemporary eyewitness accounts in Arabic literature. These productions made the period the first Islamic space to be imaginable in almost granular detail, as well as the source of much of what we know about antecedent “Arab” and “Islamic” history. These features gave the period an outsized place even in the pre-modern Arabic tradition. They also made it available for popularization by Jurjī Zaydān, whose Taʾrīkh al-tamaddun al-islāmī (1902-1906) proved formative of later attitudes in Arabic-language scholarship

The Numismatic Evidence for the Reign of Aḥmad b. Ṭūlūn
Creators: name: Treadwell, Luke
Publisher: name: Al-ʿUsur al-Wusta
Year: 2017

description: This paper re-examines the reign of Aḥmad b. Ṭūlūn (254–270/868-883), taking account of the currently available numismatic evidence. It argues for a reappraisal of the crucial triangular relationship between Ibn Ṭūlūn, the caliph al-Muʿtamid ʿalā Allāh (256–279/869-892) and the latter’s brother Abū Aḥmad (known as al-Muwaffaq billāh from 261/874). The rise of the Tulunids is situated within the context of the weakening of the Abbasid unitary state in the middle of the third century AH/ninth century CE, and the emergence of powerful provincial governors whose rise to power anticipated the eclipse of the caliphal state in the fourth/tenth century. The value of the numismatic evidence lies mainly in the names and titles that occur on the coins. These allow the historian to control the sometimes contradictory narrative of the textual sources and also raise questions about the nature and extent of Tulunid autonomy

description: Generalized lock-in amplifiers use digital cavities with Q-factors as high as 5X10^8. In this letter, we show that generalized lock-in amplifiers can be used to analyze microwave (giga-hertz) signals with a precision of few tens of hertz. We propose that the physical changes in the medium of propagation can be measured precisely by the ultra-high precision measurement of the signal. We provide evidence to our proposition by verifying the Newton's law of cooling by measuring the effect of change in temperature on the phase and amplitude of the signals propagating through two calibrated cables. The technique could be used to precisely measure different physical properties of the propagation medium, for example length, resistance, etc. Real time implementation of the technique can open up new methodologies of in-situ virtual metrology in material design.

description: Software systems are getting more and more complex. Model-driven engineering (MDE) offers ways to handle such increased complexity by lifting development to a higher level of abstraction. A key part in MDE are transformations that transform any given model into another. These transformations are used to generate all kinds of software artifacts from models. However, there is little consensus about the transformation tools. Thus, the Transformation Tool Contest (TTC) 2013 aims to compare different transformation engines. This is achieved through three different cases that have to be tackled. One of these cases is the Flowgraphs case. A solution has to transform a Java code model into a simplified version and has to derive control and data flow. This paper presents the solution for this case using NMF Transformations as transformation engine.

description: The surface of a topological crystalline insulator (TCI) carries an even number of Dirac cones protected by crystalline symmetry. We epitaxially grew high quality Pb$_{1-x}$Sn$_x$Te(111) films and investigated the TCI phase by in-situ angle-resolved photoemission spectroscopy. Pb$_{1-x}$Sn$_x$Te(111) films undergo a topological phase transition from trivial insulator to TCI via increasing the Sn/Pb ratio, accompanied by a crossover from n-type to p-type doping. In addition, a hybridization gap is opened in the surface states when the thickness of film is reduced to the two-dimensional limit. The work demonstrates an approach to manipulating the topological properties of TCI, which is of importance for future fundamental research and applications based on TCI.

description: Neutron and X-ray diffraction, magnetic susceptibility, and specific heat measurements have been used to investigate the magnetic and structural phase transitions of the spinel system Fe1+xCr2-xO4(0.0<=x<=1.0). The temperature versus Fe concentration (x) phase diagram features two magnetically ordered states and four structural states below 420 K. The complexity of the phase diagram is closely related to the change in the spin and orbital degrees of freedom induced by substitution of Fe ions for Cr ions. The systematic change in the crystal structure is explained by the combined effects of Jahn-Teller distortion, spin-lattice interaction, Fe2+-Fe3+ hopping, and disorder among Fe2+, Fe3+, and Cr3+ ions.

description: S cholars of Mamluk history are indebted to the late Ulrich Haarmann (1942-1999) for underscoring the value of travelogues by European pilgrims and diplomats as primary sources. In his pioneering article, “The Mamluk System of Rule in the Eyes of Western Travelers,” published posthumously in 2001 in the Mamlūk Studies Review (pp. 1-24), Haarmann showed that the works of Europeans who visited Egypt and Syria during the ffteenth and sixteenth centuries included valuable information on the social, natural, cultural and political history of the later Mamluk period. Their writings constitute an important corpus that can help modern-day historians to supplement and scrutinize the contents of works in Near Eastern languages. This is especially the case since European authors sometimes provide information on aspects of everyday life that, while of great interest to modern-day readers, were taken for granted and therefore left uncommented by local historiographers.

description: Amina Elbendary’s book is an attempt to reconsider the social implications of the economic crises and political transformations of the ffteenth century while taking into account the point of view of common people, especially the urban non-elite. This “non-elite” is defned as craftsmen, artisans, and tradesmen, as well as minor clerks and employees of the ruling and educational institutions of Egyptian and Syrian cities. All these members of society were traditionally marginalized in contemporary sources, but their increasing presence in the narratives of the late Mamluk period is interpreted by Elbendary as the result of social transformations. Popular protests thus ofer a unique window to observe non-elite participation in politics.

We describe the dual space to $K^{1}_θ$ in terms of a bounded mean oscillation with respect to the Clark measure $σ_α$ of $θ$. Namely, we prove that $(K^{1}_θ \cap zH^1)^* = {\rm BMO}(σ_α)$. The result implies a two-sided estimate for the operator norm of a finite Hankel matrix of size $n\times n$ via ${\rm BMO}(μ_{2n})$-norm of its standard symbol, where $μ_{2n}$ is the Haar measure on the group $\{ξ\in \mathbb{C}: ξ^{2n} = 1\}$.

description: Person re-identification is particularly challenging due to significant appearance changes across separate camera views. In order to re-identify people, a representative human signature should effectively handle differences in illumination, pose and camera parameters. While general appearance-based methods are modelled in Euclidean spaces, it has been argued that some applications in image and video analysis are better modelled via non-Euclidean manifold geometry. To this end, recent approaches represent images as covariance matrices, and interpret such matrices as points on Riemannian manifolds. As direct classification on such manifolds can be difficult, in this paper we propose to represent each manifold point as a vector of similarities to class representers, via a recently introduced form of Bregman matrix divergence known as the Stein divergence. This is followed by using a discriminative mapping of similarity vectors for final classification. The use of similarity vectors is in contrast to the traditional approach of embedding manifolds into tangent spaces, which can suffer from representing the manifold structure inaccurately. Comparative evaluations on benchmark ETHZ and iLIDS datasets for the person re-identification task show that the proposed approach obtains better performance than recent techniques such as Histogram Plus Epitome, Partial Least Squares, and Symmetry-Driven Accumulation of Local Features.

description: Based on the IR-improved bulk holographic AdS/QCD model which provides a consistent prediction for the mass spectra of resonance scalar, pseudoscalar, vector and axial vector mesons, we investigate its finite temperature behavior. By analyzing the spectral function of mesons and fitting it with a Breit-Wigner form, we perform an analysis for the critical temperature of mesons. The back-reaction effects of bulk vacuum are considered, the thermal mass spectral function of resonance mesons is calculated based on the back-reaction improved action. A reasonable melting temperature is found to be $T_c \simeq 150 \pm 7$ MeV, which is consistent with the recent results from lattice QCD simulations.

description: I t1 is surprising that the book lauded here as being on a par with Said’s seminal work Orientalism is still relatively unknown within Islamic studies, despite being published in 2011. Thomas Bauer’s Kultur der Ambiguität seems to be one of those works that draws more attention and provokes more enthusiasm in the neighboring disciplines than in in its own field.

Trauma, Technology and the 'Haunted' Male Bodies of Interwar Literature
Creators: name: Gray, Darren
Publisher: name: Leeds Beckett University
Year: 2022
Subjects: Uncategorized

description: The First World War ‘haunts’ the present day and remains in the public consciousness through literature, film and national rituals such as Remembrance Day. This haunting is highly Gothic and exposes a socio-cultural trauma caused by the Great War. Then, as now, the male soldier’s body is a site of competing narratives regarding what is perceived as ‘ideal’, ‘normal’ and ‘abnormal’. At the Great War’s outbreak, the soldier’s body was conflated with nationalism, eugenics, technological advancement and perceived as a machine-like technology of war. However, the soldier’s engagement with industrial war technologies exposed the fragility of the human body as well as the illusionary ideals and constructs which rendered it more than human. Taking an interdisciplinary approach and using a range of theoretical models, this study investigates masculinity through representations of the soldier’s body in popular and lesser-known literatures of the interwar period. Interwar literature is haunted by the spectre of the war and socio-cultural anxieties regarding gender, masculinity, and physical and mental ‘norms’ are manifested in representations of the soldier’s body. The soldier’s body is explored as a symbol of Futurist, machine-like, warrior masculinity as well as a physically and mentally broken body juxtaposed against the idealised body of the cultural imagination. The body is revealed as an object belonging to the state with a specific use-value as well as an embarrassment for the state and society when this use-value is depleted or falls short of the national ideal or ‘norm’. Analysing bodily categorisation, idealised machine-like bodies, the mutilated body, the facially-disfigured body and the shell-shocked, mentally damaged, suicidal body this study argues that all these representations highlight a deviation from a ‘norm’ in the interwar period and that these ‘monstrosities’ still have a relevance to ideas of masculinity, mental health and disability in the present day.

Isabel Toral-Niehof, Al-Ḥīra, Eine arabische Kulturmetropole im spätantiken Kontext
Creators: name: Bonner, Michael
Publisher: name: Al-ʿUsur al-Wusta
Year: 2016

description: When the phrase “late antiquity” appears today in scholarly publications on early Islam, it connotes a quest for continuity across time. That is, we expect that when authors use this phrase, they seek elements of continuity between the early Islamic world and the world that preceded it in the Near East. Until recently, however, and somewhat paradoxically, Arabia (geographically speaking, in the broadest sense) has often appeared outside this model. Arabia existed, of course, throughout the late antique period (however defned), but according to this view, its destiny and historical meaning were, frst of all, for it to be remote from its imperial, bureaucratized, urbanized, and monotheistic neighbors; and second, for it to bring discontinuity and even rupture to Near Eastern history, precisely through the rise and spread of Islam.

description: The volume under review revisits the Ghassānids, the famous Arab dynasty allied to Byzantium that has attracted considerable scholarly attention over a good century or more. This undertaking begins with a challenge to the very name granted to the dynasty: “Ghassānid” is indeed quite a misnomer. Names ending in –ids (-idès in Greek) imply a common ancestor and so one should more accurately refer to them as Jafnids, that is the descendants of one Jafna (80 and n. 2, 193).

description: An essential aspect of design of laminated plate structures in many engineering applications is the analysis of free vibration behaviour in order to model the structure for random excitations. In this regard, numerical solutions to the systems of high-order partial differential equations governing free vibration response of the structure become important. Direct approximation of such high-order systems are prone to error arising from the sensitivity of high-order numerical differentiation to noise necessitating the demand for improved solution techniques. In this work, a novel generalised inverse differential quadrature method is developed to study the dynamic behaviour of first-order shear deformable arbitrary-shaped laminated plates. The ensuing underdetermined system is operated upon by Moore–Penrose pseudo-inverse preconditioning to form a squared eigenvalue system. Free vibration solutions of square, skew, circular, and annular sector plates for different boundary conditions are obtained and validated against exact and numerical solutions in the literature and ABAQUS. It is demonstrated with numerous examples that iDQM solutions are in excellent agreement with exact solutions for square plates and the results for arbitrary shaped plates are comparable with solutions in the literature while saving up to 96% degrees of freedom required for ABAQUS solution. Finally, refined parametric studies conducted reveal that, subject to varying geometric configurations, iDQM solutions are numerically stable and potentially converge faster than DQM

description: The conference was hosted by the ERC Advanced Grant Project, “The Early Islamic Empire at Work – The View from the Regions Toward the Center,” under the direction of Stefan Heidemann. It has now entered its second phase, looking at the conceptualization and functioning of transregional and regional elites. The project is the first systematic attempt to explain the operation of the empire from a regional perspective, that is, by adopting the view from the provinces. It studies how elites, in the provinces and the caliphal center alike, contributed to the organization and management of the early Islamic empire.

description: Over the past few years, the International Medieval Congress (IMC), held at Leeds University each July, has grown immensely. Those of us interested in regions outside of Western Europe have found an ever-increasing range of sessions and scholars, coming from the rest of the world, and delving into subjects of Islamic and other non-western felds. The trend is positive, of course, allowing as it does opportunities for useful dialogue and cross-fertilization. It refects a steady broadening of the range of scholarship being done on medieval topics.

description: Recent advances suggest that encoding images through Symmetric Positive Definite (SPD) matrices and then interpreting such matrices as points on Riemannian manifolds can lead to increased classification performance. Taking into account manifold geometry is typically done via (1) embedding the manifolds in tangent spaces, or (2) embedding into Reproducing Kernel Hilbert Spaces (RKHS). While embedding into tangent spaces allows the use of existing Euclidean-based learning algorithms, manifold shape is only approximated which can cause loss of discriminatory information. The RKHS approach retains more of the manifold structure, but may require non-trivial effort to kernelise Euclidean-based learning algorithms. In contrast to the above approaches, in this paper we offer a novel solution that allows SPD matrices to be used with unmodified Euclidean-based learning algorithms, with the true manifold shape well-preserved. Specifically, we propose to project SPD matrices using a set of random projection hyperplanes over RKHS into a random projection space, which leads to representing each matrix as a vector of projection coefficients. Experiments on face recognition, person re-identification and texture classification show that the proposed approach outperforms several recent methods, such as Tensor Sparse Coding, Histogram Plus Epitome, Riemannian Locality Preserving Projection and Relational Divergence Classification.

description: In this paper we present the orbital elements of Linus satellite of 22 Kalliope asteroid. Orbital element determination is based on the speckle interferometry data obtained with the 6-meter BTA telescope operated by SAO RAS. We processed 9 accurate positions of Linus orbiting around the main component of 22 Kalliope between 10 and 16 December, 2011. In order to determine the orbital elements of the Linus we have applied the direct geometric method. The formal errors are about 5 mas. This accuracy makes it possible to study the variations of the Linus orbital elements influenced by different perturbations over the course of time. Estimates of six classical orbital elements, such as the semi-major axis of the Linus orbit a = 1109 +\- 6 km, eccentricity e = 0.016 +\- 0.004, inclination i = 101° +\- 1° to the ecliptic plane and others, are presented in this work.
