Takis Zenetos’s Conception of Remoteness: Tele-Operations as Socio-Technological Transformations
Creators: name: Charitonidou, Marianna
Publisher: name: img journal
Year: 2021

description: The article explores how Greek architect Takis Zenetos conceptualized the reinvention of the relationship between the living units and home-office conditions. Zenetos, like Yona Friedman was interested in the re-invention of the home-office conditions and in how architecture and urban design strat¬egies could respond to distance working. It also examines how architecture and urban design methods could incorporate the impact of the new conceptions of 'tele-work', 'tele-communication', and 'tele-education' on the relationships between the different social classes. Special attention is paid to how Zenetos envisioned a new mode of thinking urbanism able to be adapted to the continuous mutations in both social and technological domains. Additionally, the article sheds light on Zenetos’s critique of low density living, as well as his concep-tion of circular economy, and his intention to provide environments for heterogeneous patterns of domesticity. It also investigates which were the interdisciplinary references in Zenetos’s writings. Central for the paper is The City and the House of the Future by Zenetos, which aimed at the design of flexible systems for both buildings and infrastructures, and was based on his intention to take into consideration the accelerating mutation of the living units in the cities of the future. Zenetos and Friedman’s intention to provide comfortable, flexible and independent home-office conditions through the design of 'individual living units' using advanced technological achievements could be helpful for better understanding how architecture and urban design could respond to the challenge of providing contemporary home-office conditions.

description: Minimally invasive surgery is a surgical intervention used to examine the organs inside the abdomen and has been widely used due to its effectiveness over open surgery. Due to the hardware improvements such as high definition cameras, this procedure has significantly improved and new software methods have demonstrated potential for computer-assisted procedures. However, there exists challenges and requirements to improve detection and tracking of the position of the instruments during these surgical procedures. To this end, we evaluate and compare some popular deep learning methods that can be explored for the automated segmentation of surgical instruments in laparoscopy, an important step towards tool tracking. Our experimental results exhibit that the Dual decoder attention network (DDANet) produces a superior result compared to other recent deep learning methods. DDANet yields a Dice coefficient of 0.8739 and mean intersection-over-union of 0.8183 for the Robust Medical Instrument Segmentation (ROBUST-MIS) Challenge 2019 dataset, at a real-time speed of 101.36 frames-per-second that is critical for such procedures.
So Near, Yet So Far: Migration, the Mediterranean, and a Murderous Modernity
Creators: name: Chambers, Iain
Publisher: name: img journal
Year: 2021

description: This article examines the interplay between distance and proximity through the maritime medium of the Mediterranean, today rendered immediate by the ‘foreign’ body of the migrant. What until recently was maintained at a physical and metaphysical distance colonialism, racial hierarchies and historical amnesia, has suddenly acquired a dramatic presence with an alarming proximity. This postcolonial return operates a cut in the existing epistemological fabric. Understandings of space and time are radically reconfigured. Refused archives emerge. Other genealogies of the present enter the frame. The legal and political premises of Occidental modernity, together with the very idea of liberal democracy and rights, are violently exposed in their brutal limits. In this scenario distance and proximities are measured through mediations drawn from the area of contemporary art and visual culture; these evoke critical considerations on the limits of representation and the politics of registration.

The Distances of Presence: What Does It Mean to Be Online and Offline with Others?
Creators: name: Cavallari, Peppe
Publisher: name: img journal
Year: 2021

description: The experience of confinement and the current distancing measures keep showing up the paradoxes of distance, its constraints and its resources. Social distancing mobilises a number of technological, physical and semiotic mediations. In this way social distancing makes us see how presence is constructed, thus revealing the paradox that presence is only the effect of the organisation of several distances. Presence is always an effect of distance. Presence is the effect of differences, mediations, distances, which as a whole constitute what I call ‘play’ (or jeu), in the French sense of the word il y a du jeu, or the notion of play in terms of having slack or space to play with, meaning that there is a gap, an interstice, a delay. In order to have presence, you have to be able to create the conditions for this being ‘in between’, and this is exactly what the social uses of digital technology do. There is play, and presence consists in the harmonisation –always laborious and never finished– of these spatio-temporal disjunctions.

description: The Faddeev-Volkov model is an Ising-type lattice model with positive Boltzmann weights where the spin variables take continuous values on the real line. It serves as a lattice analog of the sinh-Gordon and Liouville models and intimately connected with the modular double of the quantum group U_q(sl_2). The free energy of the model is exactly calculated in the thermodynamic limit. In the quasi-classical limit c->infinity the model describes quantum fluctuations of discrete conformal transformations connected with the Thurston's discrete analogue of the Riemann mappings theorem. In the strongly-coupled limit c->1 the model turns into a discrete version of the D=2 Zamolodchikov's ``fishing-net'' model.

description: We describe a high-performance, compact optical frequency standard based on a microfabricated Rb vapor cell and a low-noise, external cavity diode laser operating on the Rb two-photon transition at 778 nm. The optical standard achieves an instability of 1.8x10$^{-13}$/$\sqrtτ$ for times less than 100 s and a flicker noise floor of 1x10$^{-14}$ out to 6000 s. At long integration times, the instability is limited by variations in optical probe power and the AC Stark shift. The retrace was measured to 5.7x10$^{-13}$ after 30 hours of dormancy. Such a simple, yet high-performance optical standard could be suitable as an accurate realization of the SI meter or, if coupled with an optical frequency comb, as a compact atomic clock comparable to a hydrogen maser.

Chemical, structural and electronic properties of graphite fluorosulfate derivatives
Creators: name: Karunanithy, Somasundaram
Publisher: name: University of British Columbia
Year: 2010

description: Emphasis is placed in this dissertation on (a) the development of new synthetic routes to, and (b) the structural characterization of novel graphite intercalation compounds. Chemical conversions such as substitution- , addition - , oxidation - or reduction - reactions as routes to new acceptor intercalation compounds of graphite have been systematically investigated. Suitable starting materials C[sub n]SO₃F, with n~7 as limiting composition, and C[sub n]BrSO₃F, with n~12 for stage 1 intercalation compounds are formed by oxidative intercalation of bis(fluorosulfuryl) peroxide, S₂O₆F₂ , or bromine (I) fluorosulfate, BrSO₃F,respectively. For C₇SO₃F an ionic formulation as C₇₊SO₃F₋ is proposed, however close anion packing causes covalent anion-cation interaction, primarily through oxygen, resulting in backdona-tion of charge and a lowering of the ionic salt limit. Substitution of SO₃F₋ by trifluoromethylsulfate, SO₃CF₃₋, or hexafluoroantimonate (V), SbF₅ , is achieved by solvolysis of C₇SO₃F in excess trifluoromethylsulfuric acid, HSO₃CF₃, or antimony (V) fluoride, SbF₅ to yield C₁₂SO₃CF₃, or C₈SbF₆ respectively. The former is also formed from C₁₂BrSO₃F, and HSO₃CF₃. Add it ion of arsenic (V) fluoride, AsF₅ to C₇SO₃F produces C₁₄+[AsF₅ (SO₃F)] . The same reaction type, or more generally "successive intercalation", is used when f.luoro-sulfuric acid, HSO₃F is added to higher stage binary graphite f uorosulf ates , e.g. C₁₄SO₃F to form acid fluorosulfates, in this case C₁₄SO₃F . HSO₃F[sub 1.05]. Materials similar in composition but with different spectroscopic and electronic properties are formed by "simultaneous intercalation" of controlled amounts of S₂O₆F₂ in HSO₃F solution, and two different packing modes "homogeneous" and "heterogeneous" are suggested. Intercalate Oxidation is found in the reaction of C₁₂BrSO₃F with S₂O₆F₂ to give C₁₆Br(SO₃F)₃, which may in turn undergo intercalate reduction to give C₁₂BrSO₃F. Intercalate disproportion at ion and de composition are encountered when graphite and BrSO₃F are reacted at 10 5 - 110°C to give C₂₀BrF(SO₃F)₂. Structural models are based on X-ray powder diffraction to obtain c axis spacings and the' stage index, Raman spectroscopy (backscattering configuration) to obtain staging information from graphite lattice mode shifts and to observe in rare cases intercalate vibrations, ¹⁹F and where suitable ¹H nuclear magnetic resonance (using Fourier transform techniques) to obtain information on the nature and packing of intercalates, and last but not least on complete quantitative chemical analysis for information on bulk composition and sample purity. Electronic properties of these highly conducting materials are probed occasionally by electron spin resonance spectroscopy and more thoroughly by measuring the basal plane electrical conductivities employing a contactless radio frequency induction method.

description: The graphene superlattice equation, a modified sine-Gordon equation, governs the propagation of solitary electromagnetic waves in a graphene superlattice. This equation has kink solutions without explicit analytical expression, requiring the use of quadrature methods. The inelastic collision of kinks and antikinks with the same but opposite speed is studied numerically for the first time; after their interaction they escape to infinity when its speed is either larger than a critical value or it is inside a series of resonance windows; otherwise, they form a breather-like state that slowly decays by radiating energy. Here, the fractal structure of these resonance windows is characterized by using a multi-index notation and their main features are compared with the predictions of the resonant energy exchange theory showing good agreement. Our results can be interpreted as new evidence in favour of this theory.

Classical energy momentum tensor renormalisation via effective field theory methods

description: We apply the Effective Field Theory approach to General Relativity, introduced by Goldberger and Rothstein, to study point-like and string-like sources in the context of scalar-tensor theories of gravity. Within this framework we compute the classical energy-momentum tensor renormalization to first Post-Newtonian order or, in the case of extra scalar fields, up to first order in the (non-derivative) trilinear interaction terms: this allows to write down the corrections to the standard (Newtonian) gravitational potential and to the extra-scalar potential. In the case of one-dimensional extended sources we give an alternative derivation of the renormalization of the string tension enabling a re-analysis of the discrepancy between the results obtained by Dabholkar and Harvey in one paper and by Buonanno and Damour in another, already discussed in the latter.

Close-Up-Ness: Masks, Screens, and Cells

Publisher: name: img journal

description: The pandemic reshapes not only our habits, but also our environment. It does so by supporting the creation of existential bubbles –often in the form of restrained cells– in which we shrink our range of action, but also in which we can feel safe. And it does so mostly thanks to two media that the pandemic brings to the fore and that deeply affect their users’ spatial perception: the mask and the screen. I will start from these media and their ability to remediate our usual spatial coordinates, and then conclude with the bubble and the cell as an increasingly mediated form of spatiality.

Semiotics of Distances in Virtual and Augmented Environments
Creators: name: Biggio, Federico
Publisher: name: img journal
Year: 2021

description: The interpretations of communication practices technologically mediated by immersive devices insist on the theme of distance to highlight prototypical aspects of mediation, from the rarefaction of enunciative and referential distance, to that which leads to the solipsistic isolation of the user behind a screen. Tracing the semantic articulation of these interpretations, the contribution intends to place particular emphasis on the media of virtual and augmented reality, and on how they remedy the concept of distance by investing it in new meaning. In particular, we will focus on the illusory cancellation of the distance that occurs during an immersive experience and the establishment of a critical distance in the user, linked to the emergence of a meta experiential competence, by means of the installation of an interstitial device such as the prosthesis and the interface.

description: We study the effect of the presence of a regular substrate pattern on the irreversible adsorption of nanosized and colloid particles. Deposition of disks of radius $r_0$ is considered, with the allowed regions for their center attachment at the planar surface consisting of square cells arranged in a square lattice pattern. We study the jammed state properties of a generalized version of the random sequential adsorption model for different values of the cell size, $a$, and cell-cell separation, $b$. The model shows a surprisingly rich behavior in the space of the two dimensionless parameters $α=a/2r_0$ and $β=b/2r_0$. Extensive Monte Carlo simulations for system sizes of $500\times500$ square lattice unit cells were performed by utilizing an efficient algorithm, to characterize the jammed state morphology.

description: This deliverable is part of the final report of the “Towards FAIR Data Steward as profession for the Lifesciences” project. The full report can be found at https://doi.org/10.5281/zenodo.3471707. It provides the detailed description of the function (responsibilities and tasks), competencies (knowledge, skills and abilities) and learning objectives for the three data steward roles (‘policy’, ‘research’ and ‘infrastructure’), structured by eight competence areas. In the “Towards FAIR Data Steward as profession for the Lifesciences” project (https://zenodo.org/communities/nl-ds-pd-ls), based on the literature and consultations, three different data steward stakeholder-fields were defined in the data stewardship landscape, depending on their interaction with specific stakeholders. All three stakeholder-fields together ensure that research carried out at institutes and in projects produces FAIR data along the data life cycle. Data stewards find themselves positioned at different positions in this landscape as they interface and communicate between these different stakeholder groups. The three stakeholder-fields are characterised by their own expertise and terminology. Data stewards can communicate between these stakeholder groups and hence provide the interface between fields of expertise. To indicate the particular or main focus of a data steward, three different data steward roles can be defined (‘policy’, ‘research’ and ‘infrastructure’). For all three data steward roles, eight competence areas were defined. The responsibilities and tasks in these eight competence areas can be seen as different aspects of the function that the data steward has. In practice, one data steward in a department may have all roles or, in case of multiple data stewards, roles may be divided between different persons. The responsibilities and tasks per competence area are formulated according to the focus of the data steward. In case a data steward combines the focus on for instance policymakers (data steward – policy) and researchers (data steward – research), this data steward will also have a combination of the responsibilities and tasks defined for these two data stewardship roles.

Photographing Everything and Seeing Nothing: Travel Selfies as Performance, Affirmation of Social-Collective Perception, Spatial Collapse
Creators: name: Belden-Adams, Kris
Publisher: name: img journal
Year: 2021

description: In White Noise, Don DeLillo wrote of a welltrafficked tourist destination he called “The Most Photographed Barn in America.” Because it is known through a proliferation of photographs, he suggests, “no one sees the barn” anymore. Thus, making a picture of the barn is not about ‘looking’, but akin to “taking pictures of taking pictures” –a performative mass social ritual of image-making. This behavior also is a relational means of collapsing physical space to connect psychologically and virtually with larger narratives of the human experience for both the selfie subject and their social-media followers. Thus, travel selfies remediate physical and psychological distances and, in Walter Benjamin’s terms, “bring things spatially and humanly closer.” This essay takes a closer look the reframing of both physical distance and psychological presence by digital travel selfies. Rather than being a means of producing subjects/objects to behold and to archive as ‘embalmed’ memories or artifacts of personal history for later review, digital social-media travel photographs are driven by different relational impulses: the collapse of material conceptions of time and space, the performance and promotion of self-as-‘avatar’, the dissolution of psychological space between viewer and subject, and by communal/network participation.

The topologically twisted index of $\mathcal N=4$ SU($N$) Super-Yang-Mills theory and a black hole Farey tail

description: We investigate the large-$N$ asymptotics of the topologically twisted index of $\mathcal N=4$ SU($N$) Super-Yang-Mills (SYM) theory on $T^2\times S^2$ and provide its holographic interpretation based on the black hole Farey tail. In the field theory side, we use the Bethe-Ansatz (BA) formula, which gives the twisted index of $\mathcal N=4$ SYM theory as a discrete sum over Bethe vacua, to compute the large-$N$ asymptotics of the twisted index. In a dual $\mathcal N=2$ gauged STU model, we construct a family of 5d extremal solutions uplifted from the 3d black hole Farey tail, and compute the regularized on-shell actions. The gravitational partition function given in terms of these regularized on-shell actions is then compared with a canonical partition function derived from the twisted index by the inverse Laplace transform, in the large-$N$ limit. This extends the previous microstate counting of an AdS$_5$ black string by the twisted index and thereby improves holographic understanding of the twisted index.

Separating Bodies, Synchronising Minds: The Role of Digital Technology in Mediating Distance
Creators: name: Bachimont, Bruno
Publisher: name: img journal
Year: 2021

description: Digital technology reconfigures the organization and status of archives. Immersed in the eternal present of their technological youth necessary for their consultation, digital archives potentially no longer bear the marks of time, whereas they show the past. They gain a new appetence, based on the communication uses of the moment. But how then to give them their sense of archive, how to restore their own temporality? The challenge is to allow what we call 'historical empathy' without falling into psychological anachronism. We argue here that the mediatization of digital audiovisual archives must allow us to feel concerned, with the concessions no doubt necessary to the technology and aesthetics of the moment, while perceiving the strangeness of the contents and the definitively bygone aspect of this past. It is therefore a particular critical hermeneutic to build, where mediation must show a past that technology displays in a permanent and persistent contemporaneity.

It is shown that the relation changes little, although both transport coefficients independently are subject to large modifications at the NLO level. This finding confirms that the relationship is robust.

Spheres of Action. The Technological Shift of Control
Creators: name: Arielli, Emanuele
Publisher: name: img journal
Year: 2021

description: Social interaction and experience are defined by their action possibilities; that is, they can be analyzed from the perspective of performative control (or lack thereof), namely their dynamics of activity and passivity. What I am able to influence in my environment and what lies beyond my reach determines my disposition and identity in relation to others. In this regard, media and communication devices are not only technical forms capable of modulating physical distance, but they can also transform the structure of action possibilities, rearranging the relationship between who controls whom, between what is possible and not possible. From this standpoint, the present paper will suggest a different take on the well-known dichotomy presence/distance, reframing it through the opposition activity/passivity, or controllability/non-controllability, seen as a relevant perspective in investigating the nature of mediated experience.

The dependence of the renormalization and factorization scales on the total cross section, and the effects on the K-factor due to the uncertainty of parton distribution function(PDF) have been carefully investigated. By considering soft-gluon resummation effects to all order in $α_s$ of leading logarithm, we present the transverse momentum distributions of the final $eμ$ pair.

description: There is a substantial rise in the global incidence of obesity. Brown rice contains metabolic substances that can help minimize the prevalence of obesity. This study evaluated nine brown rice varieties using probiotic fermentation using Pediococcus acidilacti MNL5 to enhance bioactive metabolites and their efficacy. Among the nine varieties, FBR-1741 had the highest pancreatic lipase inhibitory efficacy (87.6 ± 1.51%), DPPH assay (358.5 ± 2.80 mg Trolox equiv./100 g, DW), and ABTS assay (362.5 ± 2.32 mg Trolox equiv./100 g, DW). Compared to other fermented brown rice and FBR-1741 varieties, UHPLC-Q-TOF-MS/MS demonstrated significant untargeted metabolite alterations. The 17 most abundant polyphenolic metabolites in the FBR-1741 variety and 132 putative targets were assessed for obesity-related target proteins, and protein interaction networks were constructed using the Cystoscope software. Network pharmacology analysis validated FBR-1741 with active metabolites in the C. elegans obesity-induced model. Administration of FBR-1741 with ferulic acid improved lifespan decreased triglycerides and suppressed the expression of fat-related genes. The enhanced anti-obesity properties of FBR-1741 suggest its implementation in obesity-functional food.

On the Distance and Proximity of a Visual Object as a Chiasmic Notion

description: Through a series of short analyses of visual objects the article questions the nature of the dialectic distance/proximity. This dialectic actually concerns a boundary that is at the same time necessary for its articulation, but also only partially expressible within it: the boundary between spectator and observed object/image/medium. By trying to understand what distance is through the definition of some of its opposite forms (immediacy, oceanic feeling, Merleau-pontian flesh of the world), we will look for an answer to this complexity through the intelligence of the images themselves. The chiasmic nature of the relationship between the seeing subject and the seen object therefore seems to become a central theme.

description: We report muon spin relaxation measurements on the magnetic structures of RBaCo_2O_5.5 with R=Y, Tb, Dy, and Ho. Three different phases, one ferrimagnetic and two antiferromagnetic, are identified below 300 K. They consist of different ordered spin state arrangements of high-, intermediate-, and low-spin Co^3+ of CoO_6 octahedra. Phase separation into well separated regions with different spin state order is observed in the antiferromagnetic phases. The unusual strongly anisotropic magnetoresistance and its onset at the FM-AFM phase boundary is explained.

description: This paper proposes new practical design tools for the robust motion control systems based on disturbance observer (DOB). Although DOB has long been used in several motion control applications, it has insufficient analysis and design tools. The paper proposes a new practical robustness constraint, which improve the robustness at high frequencies, on the bandwidth of a DOB and nominal inertia. Although increasing the bandwidth of a DOB and nominal inertia improves the performance and stability, they are limited by the robustness constraint. Besides, a novel stability analysis method is proposed for reaction force observer (RFOB) based robust force control systems. It is shown that not only the performance, but also the stability changes significantly by the imperfect identification of inertia and torque coefficient. The robustness and stability of a DOB based motion control system are improved by proposing new design tools. The validity of the proposals are verified by experimental results.

A Case of Subdominant/Suppressed "High Energy" Contribution to the Baryon Asymmetry of the Universe in Flavoured Leptogenesis

description: The CP-violation necessary for the generation of the baryon asymmetry of the Universe $Y_B$ in the "flavoured" leptogenesis scenario can arise from the "low energy" PMNS neutrino mixing matrix $U$ and/or from the "high energy" part of neutrino Yukawa couplings, which can mediate CP-violating phenomena only at some high energy scale. The possible interplay between these two types of CP-violation is analysed. The type I see-saw model with three heavy right-handed Majorana neutrinos having hierarchical spectrum is considered. We show that in the case of inverted hierarchical light neutrino mass spectrum, there exist regions in the corresponding leptogenesis parameter space where the relevant "high energy" phases have large CP-violating values, but the purely "high energy" contribution in $Y_B$ plays a subdominant role in the production of baryon asymmetry compatible with the observations. In some of these regions the purely "high energy" contribution in $Y_B$ is so strongly suppressed that one can have successful leptogenesis only if the requisite CP-violation is provided by the Majorana phase(s) in the neutrino mixing matrix.

Manganese, rhenium and rhodium complexes containing pyrazolylgallate ligands
Creators: name: Louie, Brenda Maureen
Publisher: name: University of British Columbia

description: Dimethylbis(1-pyrazolyl)gallate anions reacted with [Re(CO)₄Cl]₂ to form unstable rhenium tetracarbonyl complexes of the type [Me₂Ga(C₃HN₂R₂)₂]Re(CO)₄ (R=H or Me). These compounds reacted with PPh₃ or pzH, the nucleophile displacing the carbonyl group mutually cis to both donor sites of the chelating, bidentate ligand. Novel bidentate dimethylmonoCl-pyrazolyl)hydroxogallate ligands have been prepared and four rhenium complexes incorporating these ligands, [Me₂Ga(C₃HN₂R₂)(OH)]Re(CO)₃X (R=H or Me; X=CO or PPh₃) are discussed. The phosphino bridged rhenium molecule, [Me₂Ga(pz)(PPh₂) ] Re(CO)₅ has also been considered. The reactions between various tridentate unsymmetric mono-(1-pyrazolyl) gallate ligands and either [Re (CO) ₄Cl]₂or Mn (CO)₅ -Br resulted in a series of tricarbonyl products. The nitrosylations of selected pyrazolylgallate rhenium species are discussed. The exposure of these nitrosylated cations to a hydride source did not lead to the isolation, or spectroscopic identification, of any reduced coordinated carbonyl moieties. In addition, selected pyrazolylgallate rhenium tricarbonyl or nitrosyl cationic species could not be induced to undergo carbonyl metathesis with tertiary phosphines. The unique stereoisomers formed from the reactions between [Re(CO)₄Cl]₂and tridentate pyrazolylgallate anions containing a chiral carbon are also discussed. A series of rhodium(I) complexes containing the [Me₂Ga(pz)₂]⁻ bidentate ligand have been prepared. These molecules were found to be stereochemically nonrigid in solution. Although one compound containing the more sterically demanding [Me₂Ga(pz")₂ ]⁻ anion could be isolated, the majority of reactions with this ligand resulted in the formation of extremely stable 3,5 dimethylpyrazolyl bridged rhodium dimers, together with [Me₂Ga(μ-pz")]₂. The reaction of [MeGa(pz)₃] ⁻ with [Rh(CO)₂Cl]₂ resulted in the novel triply carbonyl bridged dimer [MeGa (pz)₃]₂Rh₂(μ-CO)₃. The first examples.of transition metal carbonyl species containing a meridionally coordinated unsymmetric mono(1-pyrazolyl) gallate tridentate ligand have been discussed, namely [Me₂Ga(pz) (OCH₂CH₂NMe₂) ]Rh(CO)[sub n] (n=l and 2). In addition the first example of a mixed transition metal pyrazolylgallate complex, [MeGa(pz)₃]MoRh(μ-CO)₂ (CO)(PPh₃)₂, is presented. None of the novel pyrazolylgallate rhodium species prepared exhibited measurable activity as catalysts for the hydrogenation of 1-hexene or cyclohexene.

description: The group of the p-brane world volume preserving diffeomorphism is considered. The infinite-dimensional spinors of this group are related, by the nonlinear realization techniques, to the corresponding spinors of its linear subgroup, that are constructed explicitly. An algebraic construction of the Virasoro and Neveu-Schwarz-Ramond algebras, based on this infinite-dimensional spinors and tensors, is demonstrated.

Stability of sedimenting flexible loops

description: We study the behaviour of circular flexible loops sedimenting in a viscous fluid by numerical simulations and linear stability analysis. The numerical model involves a local slender-body theory approximation for the flow coupled to the Euler-Bernoulli elastic forces for an inextensible fibre. Starting from an inclined circle, we simulate the dynamics using truncated Fourier modes to observe three distinct regimes of motion: absolute stability, two-, and three-dimensional dynamics, depending on therelative importance of elastic and gravitational forces. We identify the governing parameter and develop a simple semi-analytic stability criterion, which we verify numerically. In all cases, sedimenting loops converge to stable, planar shape equilibria with one free parameter related to the initial conditions and material properties of the fibre.

description: We consider the problem of designing a fair scheduling algorithm for discrete-time constrained queuing networks. Each queue has dedicated exogenous packet arrivals. There are constraints on which queues can be served simultaneously. This model effectively describes important special instances like network switches, interference in wireless networks, bandwidth sharing for congestion control and traffic scheduling in road roundabouts. Fair scheduling is required because it provides isolation to different traffic flows; isolation makes the system more robust and enables providing quality of service. Existing work on fairness for constrained networks concentrates on flow based fairness. As a main result, we describe a notion of packet based fairness by establishing an analogy with the ranked election problem: packets are voters, schedules are candidates and each packet ranks the schedules based on its priorities. We then obtain a scheduling algorithm that achieves the described notion of fairness by drawing upon the seminal work of Goodman and Markowitz (1952). This yields the familiar Maximum Weight (MW) style algorithm. As another important result we prove that algorithm obtained is throughput optimal. There is no reason a priori why this should be true, and the proof requires non-traditional methods.

description: One of the major science goals of the Visible Emission Line Coronagraph (VELC) payload aboard the Aditya-L1 mission is to map the coronal magnetic field topology and the quantitative estimation of longitudinal magnetic field on routine basis. The infrared (IR) channel of VELC is equipped with a polarimeter to carry out full Stokes spectropolarimetric observations in the Fe XIII line at 1074.7~nm. The polarimeter is in dual-beam setup with continuously rotating waveplate as the polarization modulator. Detection of circular polarization due to Zeeman effect and depolarization of linear polarization in the presence of magnetic field due to saturated Hanle effect in the Fe~{\sc xiii} line require high signal-to-noise ratio (SNR). Due to limited number of photons, long integration times are expected to build the required SNR. In other words signal from a large number of modulation cycles are to be averaged to achieve the required SNR. This poses several difficulties. One of them is the increase in data volume and the other one is the change in modulation matrix in successive modulation cycles. The latter effect arises due to a mismatch between the retarder's rotation period and the length of the signal detection time in the case of VELC spectropolarimeter (VELC/SP). It is shown in this paper that by appropriately choosing the number of samples per half rotation the data volume can be optimized. A potential solution is suggested to account for modulation matrix variation from one cycle to the other.

Does a black hole rotate in Chern-Simons modified gravity?

description: Rotating black hole solutions in the (3+1)-dimensional Chern-Simons modified gravity theory are discussed by taking account of perturbation around the Schwarzschild solution. The zenith-angle dependence of a metric function related to the frame-dragging effect is determined from a constraint equation independently of a choice of the embedding coordinate. We find that at least within the framework of the first-order perturbation method, the black hole cannot rotate for finite black hole mass if the embedding coordinate is taken to be a timelike vector. However, the rotation can be permitted in the limit of $M/r \to 0$ (where $M$ is the black hole mass and $r$ is the radius). For a spacelike vector, the rotation can also be permitted for any value of the black hole mass.
