description: With more and more people shopping online, companies deal with customer data input not only in high volume but also dynamic. In order to attract target customers more effectively and to provide customers with more personalized services, how to automatically extract personal preference from the real-time data and make real-time recommendation has been growing in importance for businesses in the competitive modern society. Current data analysis methods for online shopping recommendation largely rely on historical transaction record. Analyses have indicating that next items a customer would like to buy not only depend on one’s past historical records but on the item currently being put into the shopping cart. This paper designs an engine to combine each customer’s past transaction and current shopping cart data to dynamically infer one’s preference for the next items. The design, Transaction-Data Based Real-time Preference Inference Engine (TRPIE), consists of two innovative ideas. The first exploits the purchasing sequence information and turns one’s purchase history into a temporal series of data, where a customer’s dynamic purchasing behaviour information lies. The second is a design of a two-layer Recurrent Neural Network (RNN) for extracting personal purchasing preference pattern from the temporal series of data to infer preference of next items. A reference implementation of TRPIE design integrates existing tools such as Keras, tensorflowTM, sklearnTM, and MlxtendTM. Test results over real data from 1,374 people show that prediction accuracy has doubled that obtained by a basket analysis method, which ignores sequentiality of purchasing items.

description: In this letter, we investigate the geometrically tailorable elasticity in the twisting behavior of biomimetic scale-covered slender soft substrate. Motivated by our qualitative experiments showing a significant torsional rigidity increase, we develop an analytical model and carry out extensive finite element (FE) simulations to validate our model. We discover a regime differentiated and reversible mechanical response straddling linear, nonlinear, and rigid behavior. The response is highly tailorable through the geometric arrangement and orientation of the scales. The work outlines analytical relationships between geometry, deformation modes and kinematics, which can be used for designing biomimetic scale-covered metamaterials.

description: We propose a new self-normalized method for testing change points in the time series setting. Self-normalization has been celebrated for its ability to avoid direct estimation of the nuisance asymptotic variance and its flexibility of being generalized to handle quantities other than the mean. However, it was developed and mainly studied for constructing confidence intervals for quantities associated with a stationary time series, and its adaptation to change-point testing can be nontrivial as direct implementation can lead to tests with nonmonotonic power. Compared with existing results on using self-normalization in this direction, the current article proposes a new self-normalized change-point test that does not require prespecifying the number of total change points and is thus unsupervised. In addition, we propose a new contrast-based approach in generalizing self-normalized statistics to handle quantities other than the mean, which is specifically tailored for change-point testing. Monte Carlo simulations are presented to illustrate the finite-sample performance of the proposed method. Supplementary materials for this article are available online.
GeV Photons from Ultra High Energy Cosmic Rays accelerated in Gamma Ray Bursts
Creators: name: Vietri, Mario
Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Gamma-ray bursts are produced by the dissipation of the kinetic energy of a highly relativistic fireball, via the formation of a collisionless shock. When this happens, Ultra High Energy Cosmic Rays up to 10^20 eV are produced. I show in this paper that these particles produce, via synchrotron emission as they cross the acceleration region, photons up to 300 GeV which carry away a small, ~0.01, but non-negligible fraction of the total burst energy. I show that, when the shock occurs with the interstellar medium, the optical depth to photon-photon scattering, which might cause energy degradation of the photons, is small. The burst thusly produced would be detected at Earth simultaneoulsy with the parent gamma-ray burst, although its duration may differ significantly from that of the lower energy photons. The expected fluences, ~10^{-5}-10^{-6} erg/cm^2 are well within the range of planned detectors. A new explanation for the exceptional burst GRB 940217 is discussed.

Hyperon Beta-Decay and Axial Charges of the Lambda in view of Strongly Distorted Baryon Wave-Functions

description: Within the collective coordinate approach to chiral soliton models we suggest that breaking of SU(3) flavor symmetry mainly resides in the baryon wave-functions while the charge operators maintain a symmetric structure. Sizable symmetry breaking in the wave-functions is required to reproduce the observed spacing in the spectrum of the (1/2)^+ baryons. The matrix elements of the flavor symmetric charge operators nevertheless yield g_A/g_V ratios for hyperon beta-decay which agree with the empirical data approximately as well as the successful F&D parameterization of the Cabibbo scheme. Demanding the strangeness component in the nucleon to vanish in the two flavor limit of the model, determines the structure of the singlet axial charge operator and yields the various quark flavor components of the axial charge of the Λ-hyperon. The suggested picture gains support from calculations in a realistic model using pion and vector meson degrees of freedom to build up the soliton.

description: In Folge des Klimawandels ist zu erwarten, dass Dürre und Starkregen an Häufig-keit und Intensität zunehmen. Fichtenkalamitäten und Sturzflutereignisse zeigen die Auswirkungen schon heute. Der Wasserrückhalt kann den Wasserhaushalt des Waldes verbessern und Schäden mindern. Diese Arbeit nutzt GIS-basierte Methoden zur Identifikation und Bewertung von Maßnahmen des Wasserrückhalts im Wald. Das untersuchte Einzugsgebiet befin-det sich um die Bergstadt Ruhla im Thüringer Wald. Das Gebiet wird hydrologisch über Abflussprozesse und den Topographic Wetness Index (TWI) charakterisiert. Überwiegend kommt um Ruhla Zwischenabfluss vor. Dieser kann von Forstwegen angeschnitten und über Gräben abgeleitet werden. Mit Hilfe des TWI werden Fließ-wege nachvollzogen und kritische Punkte das Wasserabflusses ermittelt. Der TWI ermöglicht die Simulation von neu eingebauten Durchlässen, Querabschlägen oder Grabenverschlüssen. Das benötigte Rückhaltevolumen für einen wirksamen dezentralen Hochwasserschutz wird abgeleitet. Es wird sichtbar, dass eine Ver-hinderung extremer Sturzflutereignisse mit Kleinrückhaltebecken im Wald allein voraussichtlich nicht möglich ist. Eine Schadensminimierung kann erreicht werden, erfordert jedoch eine deutlich höhere Anzahl von Kleinrückhalten im Wald. Her-ausfordernd sind die dafür nötigen Investitionen und der unzureichende Raum für den Bau von Rückhaltebecken in steilem Gelände. Anhand von Befahrungsversuchen aus Sachsen werden die Böden Ruhlas über-wiegend als nicht verdichtungssensibel eingeschätzt. Allerdings zeigt die Allge-meine Bodenabtragsgleichung Erosionsgefährdungen an den Steilhängen. In Kombination wird eine Karte zur standortsgerechten Feinerschließung erstellt. Die Ergebnisse liefern Entscheidungsgrundlagen im Einzugsgebiet. Die Herange-hensweise ist auf andere Regionen übertragbar. Für die Prognose von Hochwas-serscheitelminderungen sind zusätzliche Messungen und Modellierungen nötig.

description: We prove that if the local second-order structure function exponents in the inertial range remain positive uniformly in viscosity, then any spacetime $L^2$ weak limit of Leray--Hopf weak solutions of the Navier-Stokes equations on any bounded domain $Ω\subset \mathbb{R}^d$, $d= 2,3$ is a weak solution of the Euler equations. This holds for both no-slip and Navier-friction conditions with viscosity-dependent slip length. The result allows for the emergence of non-unique, possibly dissipative, limiting weak solutions of the Euler equations.

description: The Dirac-Born-Infeld action with transverse scalar fields is considered to study the dynamics of various BPS states. We first describe the characteristic properties of the so-called 1/2 and 1/4 BPS states on the D3 brane, which can be interpreted as F/D-strings ending on a D3-brane in Type IIB string theory picture. We then study the response of the BPS states to low energy excitations of massless fields on the brane, the scalar fields representing the shape fluctuation of the brane and U(1) gauge fields describing the open string excitations on the D-brane. This leads to an identification of interactions between BPS states including the static potentials and the kinetic interactions.

description: Short messages like those on Twitter or Facebook has become a very popular opinions sharing tool among Internet users. Therefore micro blogging web-sites are nowadays rich sources of data for opinion mining and sentiment analysis. However it is challenging because of the limited contextual information that they normally contains. Furthermore the greatest benefit can be achieved by collecting sentiment class in real time - when the post is published, in order to react as soon as possible. Nevertheless, most existing solutions are limited in centralized environments only. thus, they can only process at most a few thousand tweets. Such a sample, is not representative to define the sentiment polarity towards a topic due to the massive number of tweets published daily. Sample analysis has been performed using Machine Learning methodologies alongside with Natural Language Processing techniques and utilizes Apache Spark’s Machine learning library, MLlib, on a labelled (positive/negative) corpus containing 4234 tweets regarding Presidential Election in USA in 2016. The analysis has been completed using distributed Apache Spark environment with simulated stream of data from Kafka database.

description: In this paper, we investigate the resource allocation problem for D2D communications underlaying wireless powered communication networks, where multiple D2D pairs harvest energy from a power station equipped with multiple antennas and then transmit information signals simultaneously over the same spectrum resource. The aim is to maximize the sum throughput via joint time scheduling and power control, while satisfying the energy causality constraints. The formulated non-convex problem is first transformed into a nonlinear fractional programming problem with a tactful reformulation. Then, by leveraging D.C. (difference of two convex functions) programming, a suboptimal solution to the non-convex problem is obtained by iteratively solving a sequence of convex problems. Simulation results demonstrate that the proposed scheme works well in different scenarios and can significantly improve the system throughput compared with the-state-of-the-art schemes.

It is shown that the large polarized antiquark flavor asymmetry predicted by model calculations in the large-N_c limit (chiral quark-soliton model) has a dramatic effect on the double spin asymmetries in high mass lepton pair production, as well as on the single spin asymmetries in lepton pair production through $W^\pm$-bosons at $M^2 = M_W^2$.

description: Wastewater treatment plants (WWTPs) are the important source of micro(nano)plastics (MNPs) and pollutants (e.g. chemicals, antibiotic resistance genes (ARGs) and pathogens) in natural environment, where the interaction in these co-existing substances has become an increasing concern. This work outlines the sources of MNPs and their interaction with pollutants in WWTPs, and assesses the potential risks after being discarded into natural environment. The sources of MNPs in WWTPs mainly include personal care products, washing clothes, surface runoff and atmospheric deposition as well as the inherent plastic equipment in WWTPs. MNPs can interact with various pollutants including ARGs and microorganisms, and organic and inorganic chemicals such as persistent organic pollutants antibiotics, and metals mainly through π-π, hydrophobic, electrostatic and hydrogen-bonding interactions and biofilm formation. Additionally, the WWTP conditions (e.g. pH, temperature) and components (e.g. dissolved organic matter, salinity and suspended particulates) can affect the interaction processes by modifying the sorption sites of MNPs and changing the property of MNPs and pollutants. Once being discharged into natural media, the individual and joint toxicological impacts of MNPs and associated pollutants to organisms via ingestion would be induced. As for the knowledge gap, more attentions should be focused on the contribution in various sources of MNPs and their interaction (especially submicron- to micron-size ranges) with ARGs, to improve understanding of the sources and pollution of MNPs and the combined risk with pollutants in natural environment.

description: A thorough study is performed on pair production and signatures of supersymmetric neutralinos in the MSSM at LEP2. Particular attention is paid to the region of the SuSy parameter space where the associated production of lightest and next-to-lightest neutralinos is the only visible allowed supersymmetric process. In that region, the signal is critically dependent on the selectron masses m(e_L,R). For sqrt(s)/2 < m(e_L,R) < 200-300 GeV and charginos above the threshold for pair production, neutralinos arising from e+e- --> X0(1)X0(2) could be the only SuSy signal detectable at LEP2.

description: We investigated a bulk viscous fluid universe with cosmological constant Λ by assuming that the bulk viscosity to be proportional to the Hubble parameter. We found that for an expanding universe, the (relative) matter density will be always greater than a non-zero constant, and tends to this non-zero constant in the future. We show that the bulk viscosity model has a significantly better fitting to the combined SNeIa + CMB + BAO + H(z) data than the ΛCDM model. Generally, the evolution or values of some cosmological parameters predicted by the bulk viscosity model do not deviate significantly from which are obtained from the ΛCDM model since the bulk viscosity coefficient obtained from the astronomical observational data is so small. We also made a statefinder analysis of the bulk viscosity model and found that the evolution of the {r, s} parameters behaves in such a way that 0 < s < 1, 0.945 < r <1, indicating the bulk viscosity model is different from the ΛCDM model.

title: Bistability in the actin cortex
Creators: name: Beta, Carsten
Publisher: name: Universität Potsdam
Year: 2019

description: Multi-color fluorescence imaging experiments of wave forming Dictyostelium cells have revealed that actin waves separate two domains of the cell cortex that differ in their actin structure and phosphoinositide composition. We propose a bistable model of actin dynamics to account for these experimental observation. The model is based on the simplifying assumption that the actin cytoskeleton is composed of two distinct network types, a dendritic and a bundled network. The two structurally different states that were observed in experiments correspond to the stable fixed points in the bistable regime of this model. Each fixed point is dominated by one of the two network types. The experimentally observed actin waves can be considered as trigger waves that propagate transitions between the two stable fixed points.

Structural analysis reveals that 1 is a 1D coordination polymer with chains approximately parallel to the a-axis, linked by H-bonding interactions to form a 3-D arrangement. The uptake results for six dyes with different size and different charges revealed that 1 can adsorb neutral red and hardly adsorb the other dyes.

description: There has been much research regarding the perceptions, preferences, behaviour, and responses of people exposed to flooding and other nat- ural hazards. Cross-sectional surveys have been the predominant method applied in such research. While cross-sectional data can provide a snapshot of a respondent’s behaviour and perceptions, it cannot be assumed that the respondent’s perceptions are constant over time. As a result, many important research questions relating to dynamic processes, such as changes in risk perceptions, adaptation behaviour, and resilience cannot be fully addressed by cross-sectional surveys. To overcome these shortcomings, there has been a call for developing longitudinal (or panel) datasets in research on natural hazards, vulnerabilities, and risks. However, experiences with implementing longitudinal surveys in the flood risk domain (FRD), which pose distinct methodological challenges, are largely lacking. The key problems are sample recruitment, attrition rate, and attrition bias. We present a review of the few existing longitudinal surveys in the FRD. In addition, we investigate the potential attrition bias and attrition rates in a panel dataset of flood-affected households in Germany. We find little potential for attrition bias to occur. High attrition rates across longitudinal survey waves are the larger concern. A high attrition rate rapidly depletes the longitudinal sample. To overcome high attrition, longitudinal data should be collected as part of a multisector partnership to allow for sufficient resources to implement sample retention strategies. If flood-specific panels are developed, different sample retention strategies should be applied and evaluated in future research to understand how much-needed longitudinal surveying techniques can be successfully applied to the study of individuals threatened by flooding.

description: The standard scenario of cosmology predicts a measurable amount for linear polarization of the Cosmic Microwave Background radiation (CMB) via Thomson scattering, while through this scenario, the generation of circular polarization is excluded. On the another hand, the circular polarization of CMB has not been excluded in observational evidence. The generation of CMB photons circular polarization via their Compton scattering with polarized cosmic electrons is considered in this paper. Our motivation for considering polarized Compton scattering comes from the effects of the external magnetic field in large scale, the chiral magnetic instability and new physics interactions of the cosmic electrons. It is shown that damping term of polarized Compton scattering in the presence of scalar perturbation can generate circular polarization in CMB radiation, so that the power spectrum of circular polarization of CMB $C_l^{V(S)}$ is proportional to the power spectrum of temperature anisotropy of CMB $C_l^{I(S)}$ and also $δ^2$ which is a fraction of polarized electron number density to the total one with net Left- or Right-handed polarizations. We have discussed that at least we need $δ<10^{-4}$ to find consistency with a reported upper limit of CMB circular polarization.

description: In general, the study of gradations has always represented a cornerstone in algebra theory. In particular, \textit{naturally graded} seems to be the first and the most relevant gradation when it comes to nilpotent algebras, a large class of solvable ones. In fact, many families of relevant solvable algebras have been obtained by extensions of naturally graded nilpotent algebras, i.e. solvable algebras with a well-structured nilradical. Thus, the aim of this work is introducing the concept of naturally graded for superalgebra structures such as Lie and (non-Lie) Leibniz. After having defined naturally graded Lie and Leibniz superalgebras, we characterize natural gradations on a very important class of each of them, that is, those with maximal super-nilindex.

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.

description: The hyperon-hyperon potentials due to a recent SU(3) Nijmegen soft-core potential model are incorporated within a relativistic mean field calculation of strange hadronic matter. We find considerably higher binding energy in bulk matter compared to several recent calculations which constrain the composition of matter. For small strangeness fractions, matter is dominated by a composition of nucleons, Lambdas, and Xis, and the calculated binding energy closely follows that calculated by using the hyperon potentials of our previous calculations. For larger strangeness fractions, the calculated binding energy increases substantially beyond any previous calculation due to a phase transition into Sigma and Xi dominated matter. We also compare bulk matter calculations with finite system calculations, again highlighting the consequences of reducing the Coulomb destabilizing effects in finite strange systems.

description: Sociometrically neglected children are not often liked and not often disliked by their peers. This kind of social information is known as social status. Evidence concerning internalizing behaviour of neglected children is as yet equivocal. Contradictory research results could possibly be attributed to methodological issues of social status classification methods. Therefore, we will paradigmatically emphasize insufficiencies of one social status classification method. Since arbitrary cutoffs (sociometric data) provide the basis for the categorical classification of social status groups, the classification approach lacks precision and consistency. Furthermore, social status classification discounts the multidimensional nature of a child’s social status (social status group affiliation is mutually exclusive), disregards between-peer-group differences in the sociometric data, and offers a peer-group-norm-referenced interpretation. By contrast, we will highlight some advantages of the newly introduced social status extreme points procedure, which describes a child’s social status in terms of the child’s adaptation to sociometric extreme points. The continuous social status extreme points variables offer a criterion-referenced interpretation (multidimensionality: degree of adaptation to each and every sociometric extreme point). The performance and agreement of both methods will be demonstrated using empirical data (N = 316 children within 22 school classes).

description: To understand within-person psychological processes, one may fit VAR(1) models (or continuous-time variants thereof) to multivariate time series and display the VAR(1) coefficients as a network. This approach has two major problems. First, the contemporaneous correlations between the variables will frequently be substantial, yielding multicollinearity issues. In addition, the shared effects of the variables are not included in the network. Consequently, VAR(1) networks can be hard to interpret. Second, crossvalidation results show that the highly parametrized VAR(1) model is prone to overfitting. In this article, we compare the pros and cons of two potential solutions to both problems. The first is to impose a lasso penalty on the VAR(1) coefficients, setting some of them to zero. The second, which has not yet been pursued in psychological network analysis, uses principal component VAR(1) (termed PC-VAR(1)). In this approach, the variables are first reduced to a few principal components, which are rotated toward simple structure; then VAR(1) analysis (or a continuous-time analog) is applied to the rotated components. Reanalyzing the data of a single participant of the COGITO study, we show that PC-VAR(1) has the better predictive performance and that networks based on PC-VAR(1) clearly represent both the lagged and the contemporaneous variable relations.

description: We calculate the two-loop contributions to the electric dipole moments of the electron and the neutron mediated by charged Higgs in a generic supersymmetric theories. The new contributions are originated from the potential CP violation in the trilinear couplings of the charged Higgs bosons to the scalar-top or the scalar-bottom quarks. These couplings did not receive stringent constraints directly. We find observable effects for a sizeable portion of the parameter space related to the third generation scalar-quarks in the minimal supersymmetric standard model.

Wilson loop of the heterotic sigma model and the sv-map

description: The single-valued projection (sv) is a relation between scattering amplitudes of gauge bosons in heterotic and open superstring theories. Recently we have studied sv from the aspect of nonlinear sigma models [1], where the gauge physics of open string sigma model is under the Wilson loop representation but the gauge physics of heterotic string sigma model is under the fermionic representation since the Wilson loop representation is absent in the heterotic case. There we showed that the sv comes from a sum of six radial orderings of heterotic vertices on the complex plane. In this paper, we propose a Wilson loop representation for the heterotic case and using the Wilson loop representation to show that sv comes from a sum of two opposite-directed contours of the heterotic sigma model. We firstly prove that the Wilson loop is the exact propagator of the fermion field that carry the gauge physics of the heterotic string in the fermionic representation. Then we construct the action of the heterotic string sigma model in terms of the Wilson loop, by exploring the geometry of the Wilson loop and by generalizing the nonabelian Stokes's theorem [2], [3], [4] to the fermionic case. After that, we compute some three loop and four loop diagrams as an example, to show how the sv for $ζ_2$ and $ζ_3$ arises from a sum of the contours of the Wilson loop. Finally we conjecture that this sum of contours of the Wilson loop is the mechanism behind the sv for general cases.

description: One of the official War Diaries of the First Infantry Division of the 16th Battalion (The Canadian Scottish), Canadian Expeditionary Force that cover from the time the Regiment went overseas at the start of the First World War to the time it returned to Canada in April 1919. War diaries are official records kept by the Battalions during a one month period. The diary provides a daily summary of events, actions, activities, etc. The diary begins with the Battalion in the Ronville Caves under Arras, work being carried out on the Ficheau-Telegraph Hill Switch, moving to eh front line Telegraph Hill Sector, billetting in the Carrière Wellington museum in Arras, Liet. D. Clelleand and a runner going missing and searching for them, moving to Roclincourt Corps Reserve, gas helmet inspecation, parading in kilts for the first time in 1918, work on St. Catherine's Switch, reconnaissance for a raids, and undertaking successful raids on the enemy. The diary includes a narrative of the raids on night of April 27/28, 1918 and a tally of the casualties from those three raids. The diary ends with Operation Orders and copies of the narrative about the raids.
World-volume fields and background coupling of branes

description: This is the written version of an invited talk delivered at the workshop ``Quantum gravity in the Southern Cone'' held in San Carlos de Bariloche, Argentina, January 7-10, 1998. After giving a brief introduction to the concept of branes and their role in string theory, this talk describes a method for formulating the dynamics of branes, especially those containing non-scalar moduli. Emphasis is put on the coupling of branes to fields in the low-energy background supergravity theories, and on preservation of maximal amount of manifest symmetry. Due to the nature of the workshop, the presentation is aimed at physicists who are not experts in string theory.

Finite temperature corrections to the energy-momentum tensor at one-loop in static space-times

description: Finite temperature corrections to the effective potential and the energy-momentum tensor of a scalar field are computed in a perturbed Minkoswki space-time. We consider the explicit mode decomposition of the field in the perturbed geometry and obtain analytical expressions in the non-relativistic and ultra-relativistic limits to first order in scalar metric perturbations. In the static case, our results are in agreement with previous calculations based on the Schwinger-De Witt expansion which indicate that thermal effects in a curved space-time can be encoded in the local Tolman temperature at leading order in perturbations and in the adiabatic expansion. We also study the shift of the effective potential minima produced by thermal corrections in the presence of static gravitational fields. Finally we discuss the dependence on the initial conditions set for the mode solutions.

description: The aim of this work is to study a very special family of odd-quadratic Lie superalgebras ${\mathfrak g}={\mathfrak g}_{\bar 0}\oplus {\mathfrak g}_{\bar 1}$ such that ${\mathfrak g}_{\bar 1}$ is a weak filiform ${\mathfrak g}_{\bar 0}$-module (weak filiform type). We introduce this concept after having proved that the unique non-zero odd-quadratic Lie superalgebra $({\mathfrak g},B)$ with ${\mathfrak g}_{\bar 1}$ a filiform ${\mathfrak g}_{\bar 0}$-module is the abelian $2$-dimensional Lie superalgebra ${\mathfrak g}={\mathfrak g}_{\bar 0} \oplus {\mathfrak g}_{\bar 1}$ such that $\mbox{\rm dim }{\mathfrak g}_{\bar 0}=\mbox{\rm dim }{\mathfrak g}_{\bar 1}=1$. Let us note that in this context the role of the center of ${\mathfrak g}$ is crucial. Thus, we obtain an inductive description of odd-quadratic Lie superalgebras of weak filiform type via generalized odd double extensions. Moreover, we obtain the classification, up to isomorphism, for the smallest possible dimensions, that is, six and eight.
title: The genesis of the ‘Exceptional’ Republic
title: the permanency of the political crisis and the constitution of legal emergency power in Turkey
titleType: Subtitle

description: Almost half of the political life has been experienced under the state of emergency and state of siege policies in the Turkish Republic. In spite of such a striking number and continuity in the deployment of legal emergency powers, there are just a few legal and political studies examining the reasons for such permanency in governing practices. To fill this gap, this paper aims to discuss one of the most important sources of the ‘permanent’ political crisis in the country: the historical evolution of legal emergency power. In order to highlight how these policies have intensified the highly fragile citizenship regime by weakening the separation of power, repressing the use of political rights and increasing the discretionary power of both the executive and judiciary authori- ties, the paper sheds light on the emergence and production of a specific form of legality based on the idea of emergency and the principle of executive prerogative. In that context, it aims to provide a genealogical explanation of the evolution of the excep- tional form of the nation-state, which is based on the way political society, representation, and legitimacy have been instituted and accompanying failure of the ruling classes in building hegemony in the country.
