description: Millimeter-wave (mmWave) with large spectrum available is considered as the most promising frequency band for future wireless communications. The IEEE 802.11ad and IEEE 802.11ay operating on 60 GHz mmWave are the two most expected wireless local area network (WLAN) technologies for ultra-high-speed communications. For the IEEE 802.11ay standard still under development, there are plenty of proposals from companies and researchers who are involved with the IEEE 802.11ay task group. In this survey, we conduct a comprehensive review on the medium access control layer (MAC) related issues for the IEEE 802.11ay, some cross-layer between physical layer (PHY) and MAC technologies are also included. We start with MAC related technologies in the IEEE 802.11ad and discuss design challenges on mmWave communications, leading to some MAC related technologies for the IEEE 802.11ay. We then elaborate on important design issues for IEEE 802.11ay. Specifically, we review the channel bonding and aggregation for the IEEE 802.11ay, and point out the major differences between the two technologies. Then, we describe channel access and channel allocation in the IEEE 802.11ay, including spatial sharing and interference mitigation technologies. After that, we present an in-depth survey on beamforming training (BFT), beam tracking, single-user multiple-input-multiple-output (SU-MIMO) beamforming and multi-user multiple-input-multiple-output (MU-MIMO) beamforming. Finally, we discuss some open design issues and future research directions for mmWave WLANs. We hope that this paper provides a good introduction to this exciting research area for future wireless systems.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Recently, Gimbutas et al derived an elegant representation for the Green's functions of Stokes flow in a half-space. We present a fast summation method for sums involving these half-space Green's functions (stokeslets, stresslets and rotlets) that consolidates and builds on the work by Klinteberg et al for the corresponding free-space Green's functions. The fast method is based on two main ingredients: The Ewald decomposition and subsequent use of FFTs. The Ewald decomposition recasts the sum into a sum of two exponentially decaying series: one in real-space (short-range interactions) and one in Fourier-space (long-range interactions) with the convergence of each series controlled by a common parameter. The evaluation of short-range interactions is accelerated by restricting computations to neighbours within a specified distance, while the use of FFTs accelerates the computations in Fourier-space thus accelerating the overall sum. We demonstrate that while the method incurs extra costs for the half-space in comparison to the free-space evaluation, greater computational savings is also achieved when compared to their respective direct sums.

description: An Executive Information System (EIS), as one category of a Management Support System, is a computer -based information system designed to serve the needs of executives. Although EIS implementations are increasing in number every year, knowledge about the methods and factors influencing their successful implementation is not well established.This research develops a framework for EIS implementation, examines the factors influencing its success, and contributes to the identification of techniques for measuring the success of an EIS implementation.Phase one of the research involved case studies of EIS implementation in five firms. This phase contributed towards the identification of success factors and the development of the research model. In phase two, a cross-sectional survey was conducted and the research model and propositions were empirically tested by using path analysis. As predicted, both EIS team communication skills and user attitude towards the EIS have direct positive effects on successful EIS implementation. The results suggest that high communication skills of an EIS team results in improvement in user participation, user involvement and a positive perception by EIS users regarding successful EIS implementation. Additionally, the success of EIS implementation was measured by the use of three surrogate variables: user satisfaction with information, system quality and service quality, with system quality found to be a useable single surrogate.This research provides a better understanding of EIS implementation with a useful model of successful EIS implementation being developed, and contributes to both theory and practice. From a theoretical perspective, it contributes substantially to the development of MSS implementation theory. From a practical perspective, the results provide a useful framework for project managers in the adoption or development of EIS.

description: Context. Differential rotation has a strong influence on stellar internal dynamics and evolution, notably by triggering hydrodynamical instabilities, by interacting with the magnetic field, and more generally by inducing transport of angular momentum and chemical elements. Moreover, it modifies the way waves propagate in stellar interiors and thus the frequency spectrum of these waves, the regions they probe, and the transport they generate. Aims. We investigate the impact of a general differential rotation (both in radius and latitude) on the propagation of axisymmetric gravito-inertial waves. Methods. We use a small-wavelength approximation to obtain a local dispersion relation for these waves. We then describe the propagation of waves thanks to a ray model that follows a Hamiltonian formalism. Finally, we numerically probe the properties of these gravito-inertial rays for different regimes of radial and latitudinal differential rotation. Results. We derive a local dispersion relation that includes the effect of a general differential rotation. Subsequently, considering a polytropic stellar model, we observe that differential rotation allows for a large variety of resonant cavities that can be probed by gravito-inertial waves. We identify that for some regimes of frequency and differential rotation, the properties of gravito-inertial rays are similar to those found in the uniformly rotating case. Furthermore, we also find new regimes specific to differential rotation, where the dynamics of rays is chaotic. Conclusions. As a consequence, we expect modes to follow the same trend. Some parts of oscillation spectra corresponding to regimes similar to those of the uniformly rotating case would exhibit regular patterns, while parts corresponding to the new regimes would be mostly constituted of chaotic modes with a spectrum rather characterised by a generic statistical distribution.

description: The windows of low extinction in the Milky Way (MW) plane are rare but important because they enable us to place structural constraints on the opposite side of the Galaxy, which has hitherto been done rarely. We use the near-infrared (near-IR) images of the VISTA Variables in the Vía Láctea (VVV) Survey to build extinction maps and to identify low extinction windows towards the Southern Galactic plane. Here we report the discovery of VVV WIN 1713$-$3939, a very interesting window with relatively uniform and low extinction conveniently placed very close to the Galactic plane. The new window of roughly 30 arcmin diameter is located at Galactic coordinates (l,b)= (347.4,-0.4) deg. We analyse the VVV near-IR colour-magnitude diagrams in this window. The mean total near-IR extinction and reddening values measured for this window are A_Ks=0.46 and E(J-Ks)=0.95. The red clump giants within the window show a bimodal magnitude distribution in the Ks band, with peaks at Ks=14.1 and 14.8 mag, corresponding to mean distances of D=11.0+/-2.4 and 14.8+/-3.6 kpc, respectively. We discuss the origin of these red clump overdensities within the context of the MW disk structure.

description: Electronic structures for InxGa1-xAs nanowires with [100], [110], and [111] orientations and critical dimensions of approximately 2 nm are treated within the framework of density functional theory. Explicit band structures are calculated and properties relevant to nanoelectronic design are extracted including band gaps, effective masses, and density of states. The properties of these III-V nanowires are compared to silicon nanowires of comparable dimensions as a reference system. In nonpolar semiconductors, quantum confinement and surface chemistry are known to play a key role in the determination of nanowire electronic structure. InxGa1-xAs nanowires have in addition effects due to alloy stoichiometry on the cation sublattice and due to the polar nature of the cleaved nanowire surfaces. The impact of these additional factors on the electronic structure for these polar semiconductor nanowires is shown to be significant and necessary for accurate treatment of electronic structure properties.

description: We study the generalization of $R\to 1/R$ duality to arbitrary conformally invariant sigma models with an isometry. We show that any pair of dual sigma models can be represented as quotients of a self-dual sigma model obtained by gauging different combinations of chiral currents. This observation is used to clarify the interpretation of the generalized duality as a symmetry of conformal field theory. We extend these results to $N=2$ supersymmetric sigma models.

The limits of computers in schools: an actor-network analysis

Subjects: classificationCode: 460804

description: This thesis explores educational innovation through the investigation of computer use in a school. This study is timely given the financial cost outlaid to equip schools with the latest technological paraphernalia and the volume of research findings that indicate computers have had little impact upon student achievement, or school practice in general. This study takes a first step in suggesting a rationale for these research findings.
Data for this study were collected over a one-year period from a regional primary school in Queensland. The data consist of teachers and student interviews; classroom and school observations, and various school documents. In traditional educational studies, this study would be described as an ethnographic case study. However the theoretical framework upon which this study is based modifies what is traditionally understood as an ethnographic case study.
The study of technology in an educational setting brings together both social and technical elements. However, current literature argues against the application of deterministic approaches-socially determined or technically determined, as approaches to study technology in schools. This study therefore employs a theoretical approach drawn from Actor-Network Theory that denies privilege to either the social or technical. An Actor-Network Theory approach is premised on an analytical move that treats both the technical and the social in the same way. Such an approach is neither technically determined nor socially determined.
This study draws on a theoretical framework recently developed within the field of Actor-Network Theory studies referred to as STS- Science and Technology Studies. This move, referred to as the performative turn, uses an analytical tool of performance. This study contributes to new knowledge by exploring the application of such a methodical approach to the study of an educational innovation. No other study of educational innovation using a framework of performativity has been undertaken to date.
Following the STS turn to performativity, this study takes the position that what we regard as a school can be conceptualised as a performance. This study argues that one of the implications arising from this position is that the enactment of school draws on a limited range of performances which are repeated again and again. It also argues that when teachers integrate computers into their teaching, they draw on established practices. This means that the way in which computers and technology are used in school is necessarily limited. This study also argues that computers and technology are performed in different and often contradictory ways that appear to co­ exist.
Rather than conclude in an anti-technology vein that discourages the use of technology in educational settings, this study suggests that to extend the manner in which computers are used, a necessary first step is a reexamination of the practices found in schools.

ATLAS Deliverable 1.5: Recent Mediterranean Outflow Water and Atlantic Meridional Overturning Circulation correlations
Creators: name: Mosquera Giménez, Ángela
name: Vélez-Belchí, Pedro
Publisher: name: Zenodo
Year: 2019

description: The ATLAS project works towards improving understanding of the North Atlantic Ocean, in particular, how it is connected, how it functions and how it will respond to future changes. The first step to achieve this goal is the study of the Atlantic Meridional Overturning Circulation (AMOC), since it connects deep-sea ecosystems with the transport of heat, salt, and energy in the whole Atlantic Ocean.
 The AMOC is the main contributor to the heat interchange in the North Atlantic (Kanzow et al., 2010). It consists, from a simplified point of view, of an upper transport of warm water to the north and a deep transport of cold water to the equator. Thus, the AMOC carries an important amount of heat, approximately 1.5 PW at 25°N, from the equator to high latitudes (Huisman et al., 2010), helping to regulate the climate, especially in Europe (Bryden et al., 2005). Any slowdown in the AMOC, due to both the natural variability and the anthropogenic climate change, would significantly reduce temperature in the regions around the North Atlantic and even in other parts of the world (Vellinga et al., 2002).
 The strength of the AMOC is affected by the input of freshwater in the North Atlantic. Light, fresh water entering in the North Atlantic would produce a reduction in the transport of the AMOC (Willis, 2010), while a supply of salty water, such as the Mediterranean Outflow Water (MOW), would enhance the formation of deep water (Rahmstorf, 1998), strengthening the AMOC (Reid, 1978, 1979; Artale et al., 2002; Cacho et al., 2000), and even stabilizing it (Ivanovic et al., 2014).
 The MOW is an intermediate water mass, salty and warm, that is formed when dense Mediterranean water passes through the Strait of Gibraltar and mixes with the North Atlantic Central Water (Daniault et al., 1994). This water mass spreads into the North Atlantic at an average depth of about 1100 m, and its signal can be found as far as Bermuda in the west and Rockall Trough in the north (Bozec et al., 2011). The interchange of water between the Mediterranean and the Atlantic depends on two factors: the geometry of the Strait of Gibraltar, which regulates the total volume of water able to physically pass from one basin to the other, and the density gradient, which contributes to controlling salinity and temperature exchange (Ivanovic et al., 2014).
 In this report, in order to determine if the variation of the volume of the MOW is having any effect on the fluctuation of the transport of the AMOC, we will use data from the Argo observing system and RAPID arrays to estimate if there is correlation between the inter-annual to decadal MOW distribution in the eastern Atlantic and the components of the AMOC, in particular with the upper mid-ocean transport (UMO).

description: Sterile filters incorporating endotoxin adsorption function emerged recently to pretreat dialysate liquids fed to a hemodialysis filtration process. Their application significantly enhances the survival rate during dialysis treatment as they function as sterile filters as well as an endotoxin adsorber. Little is known about the fluid flow distribution in such single use membrane modules. We report a detailed analysis of the local 3D flow field distribution in such membrane modules using magnetic resonance flow imaging. Next to pure water filtration representing the application case of endotoxin adsorption from an already pure liquid, we also used the module as a filtration device rejecting for instance colloidal silica. Such experiments performed in-situ allow the quantification of cake layer development and its concomitant redistribution of the flow field. Particularly novel is the quantification of the time evolution of local permeate flux distribution. These detailed insights of this study encourage the use of flow-MRI when designing and applying new membrane module configurations.
On the Relation of Four-Dimensional N=2,4 -- Supersymmetric String Backgrounds to Integrable Models

description: In this letter we discuss the relation of four-dimensional, $N=2$ supersymmetric string backgrounds to integrable models. In particular we show that non-Kählerian gravitational backgrounds with one $U(1)$ isometry plus non-trivial antisymmetric tensor and dilaton fields arise as the solutions of the Liouville equation or, for the case of vanishing central charge deficit, as the solutions of the continual Toda equation. When performing an Abelian duality transformation, a particular class of solutions of the continual Toda equation leads to the well-known gravitational Eguchi-Hanson instanton background with self-dual curvature tensor.

description: Stars approaching supermassive black holes (SMBHs) in the centers of galaxies can be torn apart by strong tidal forces. We study the physics of tidal disruption by a binary SMBH as a function of the binary mass ratio $q = M_2 / M_1$ and separation $a$, exploring a large set of points in the parameter range $q \in [0.01, 1]$ and $a/r_{t1} \in [10, 1000]$. We simulate encounters in which field stars approach the binary from the loss cone on parabolic, low angular momentum orbits. We present the rate of disruption and the orbital properties of the disrupted stars, and examine the fallback dynamics of the post-disruption debris in the "frozen-in" approximation. We conclude by calculating the time-dependent disruption rate over the lifetime of the binary. Throughout, we use a primary mass $M_1 = 10^6 M_\odot$ as our central example. We find that the tidal disruption rate is a factor of $\sim 2 - 7$ times larger than the rate for an isolated BH, and is independent of $q$ for $q \gtrsim 0.2$. In the "frozen-in" model, disruptions from close, nearly equal mass binaries can produce intense tidal fallbacks: for binaries with $q \gtrsim 0.2$ and $a/r_{t1} \sim 100$, roughly $\sim 18 - 40 \%$ of disruptions will have short rise times ($t_\textrm{rise} \sim 1 - 10$ d) and highly super-Eddington peak return rates ($\dot{M}_\textrm{peak} / \dot{M}_\textrm{Edd} \sim 2 \times 10^2 - 3 \times 10^3$).

The Absolute Magnitude of the Sun in Several Filters

description: This paper presents a table with estimates of the absolute magnitude of the Sun and the conversions from $vegamag$ to the AB and ST systems for several wide-band filters used in ground and space-based observatories. These estimates use the dustless spectral energy distribution (SED) of Vega, calibrated absolutely using the SED of Sirius, to set the $vegamag$ zero-points and a composite spectrum of the Sun that coadds space-based observations from the ultra-violet to the near infrared with models of the Solar atmosphere. The uncertainty of the absolute magnitudes is estimated comparing the synthetic colors with photometric measurements of solar analogs and is found to be $\sim$ 0.02 magnitudes. Combined with the uncertainty of $\sim$ 2% in the calibration of the Vega SED, the errors of these absolute magnitudes are $\sim$ 3--4%. Using these SEDs, for the three of the most utilized filters in extragalactic work the estimated absolute magnitudes of the Sun are $M_B$ = 5.44, $M_V$ = 4.81 and $M_K$ = 3.27 mag in the $vegamag$ system and $M_B$ = 5.31, $M_V$ = 4.80 and $M_K$ = 5.08 mag in AB.

description: Let $M$ be a $G$-covering of a nilpotent orbit in $\g$ where $G$ is a complex semisimple Lie group and $\g=\text{Lie}(G)$. We prove that under Poisson bracket the space $R[2]$ of homogeneous functions on $M$ of degree 2 is the unique maximal semisimple Lie subalgebra of $R=R(M)$ containing $\g$. The action of $\g'\simeq R[2]$ exponentiates to an action of the corresponding Lie group $G'$ on a $G'$-cover $M'$ of a nilpotent orbit in $\g'$ such that $M$ is open dense in $M'$. We determine all such pairs $(\g\subset\g')$.

The Gauss-Bonnet Theorem for coherent tangent bundles over surfaces with boundary and its applications

description: In [31,32,33] the Gauss-Bonnet formulas for coherent tangent bundles over compact oriented surfaces (without boundary) were proved. We establish the Gauss-Bonnet theorem for coherent tangent bundles over compact oriented surfaces with boundary. We apply this theorem to investigate global properties of maps between surfaces with boundary. As a corollary of our results we obtain Fukuda-Ishikawa's theorem. We also study geometry of the affine extended wave fronts for planar closed non singular hedgehogs (rosettes). In particular, we find a link between the total geodesic curvature on the boundary and the total singular curvature of the affine extended wave front, which leads to a relation of integrals of functions of the width of a resette.

postharvest loss reduction

description: In Sub-Saharan Africa, over 40 % of fruits and vegetables are lost between farm and consumer. Cooling produce after harvest is key to reducing these losses. Evaporative passive cooling offers a promising solution, especially for smallholder farmers in low- and middle-income countries, but challenges related to cost, scalability, and complexity limit its adoption. To address these challenges we developed the charcoal cooling blanket (CCB) an affordable and scalable storage solution for fresh produce. In a pilot study on Uganda’s tomato supply chain, we tested the CCB against natural shade, aiming to improve tomato storage and transportation. We also evaluated pre-harvest factors such as ripening stage and irrigation scheduling, along with postharvest attributes like weight, firmness, color, soluble solids content (SSC), and acidity. The CCB reduced the average ambient temperature by 1.5 °C, with a maximum reduction of up to 20 °C during the hottest periods. Relative humidity increased by 10 %, reducing tomato shriveling. Storage using the CCB led to up to 10 % less weight loss, 20 % less firmness loss, slower color change, and a 4 % increase in the SSC/pH ratio compared to ambient conditions. Moderate water stress during cultivation, combined with CCB storage, reduced weight loss in green tomatoes by 17 %. Overall, the CCB increased the quality index and shelf life of tomatoes by up to 60 %. The CCB has shown significant potential in reducing postharvest losses, making it a viable option for preserving fresh produce and improving food security in low- and middle-income countries.

Generalized Duality and Singular Strings in Higher Dimensions

name: Sfetsos, K.
Publisher: name: arXiv
Year: 1991
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Deformations of gauged WZW actions are constructed for any pair $(G,H)$ by taking different embeddings of the gauge group $H\subset G$ as it acts on the left and right of the group element $g$. This leads to models that are dual to each other, generalizing the axial/vector duality of the two dimensional black hole manifold. The classical equations are completely solved for any pair $(G,H)$ and in particular for the anti de Sitter string based on $SO(d- 1,2)/SO(d-1,1)$ for which the normal modes are determined. Duality is demonstrated for models that have the same set of normal modes. Concentrating on $SO(2,2)/SO(2,1)$, the metric and dilaton fields of the $d=3$ string as well as some of the dual generalizations are obtained. They have curvature singularities and represent new singular solutions of Einstein's general relativity in three dimensions.
