description: Η εργασία αυτή αποτελεί την εθνογραφική προσέγγιση μιας ομάδας μητέρων που προωθεί τον αποκλειστικό και παρατεταμένο θηλασμό, ως μετωνυμία της μητρικής αφοσίωσης. Η ανάλυση που επιχειρείται βασίζεται στην ανθρωπολογική παραδοχή ότι ο θηλασμός δεν είναι ένα βιολογικά προκαθορισμένο φαινόμενο αλλά μια πρακτική που υπόκειται σε κανόνες πολιτισμικούς. Η μελέτη επικεντρώνεται στις πολιτικές χρήσεις των αναπαραστάσεων της "φύσης" στο σύγχρονο, ελληνικό, αστικό χώρο
description: This study is an ethnographic research of a voluntary organization that promotes exclusive and extended breastfeeding, as a metonyme of maternal devotion. The analysis that is attempted is based on the anthropological assumption that beastfeeding in not a biologically determinded phenomenon, but a practice that is embedded in cultural normes. The research is focused in the political uses of the representations of "nature" in modern, greek urban space

description: We overview the EDABI method developed recently and combining the exact diagonalization and ab initio aspects of electron states in correlated systems and apply it to nanoscopic systems. In particular, we discuss the localization-delocalization transition for the electrons that corresponds to the Mott-Hubbard transition in bulk systems. We show, that, the statistical distribution function for electrons in a nanochain evolves from the Fermi-Dirac-like to the Luttinger-liquid-like with the increasing interatomic distance. The concept of Hubbard subbands is introduced to nanoclusters, and corresponds to the HOMO-LUMO splitting in the molecular and organic solid states. Also, the nanochains exhibit magnetic splitting (Slater-like), even without the symmetry breaking, since the spin-spin correlations extend over the whole system. Thus, the correlated nanoscopic systems exhibit unique and universal features, which differ from those of molecular and infinite systems. These features define unique properties reflecting "the Mott physics" on the nanoscale. We also employ the EDABI method to the transport properties in nanoscopic systems. For example, we show that the particle-hole symmetry is broken when the tunneling conduction through H2 molecule is calculated.

description: The polar metal is a material that hosts both polar distortion and metallicity. Such a material is expected to show exotic magneto-electric phenomena if superconducts. Here, we theoretically explore ferroelectric and superconducting properties in a series of perovskite-type oxyhydrides ATiO$_2$H (A=K, Rb, Cs) under hole-doping conditions using the first-principles calculations based on the density functional theory. Our simulation shows that these compounds host spontaneous polarization and superconductivity at optimal doping concentration. The unusual coexistence of superconductivity and large polarization (~100 $μ$C/cm$^2$) originates from weak coupling of the polar distortion and superconducting states, the reason of which is separation of the displaced atoms and spacially confined metallic carriers. Besides, the superconductivity is enhanced by the unique electronic properties near the valence band maximum: quartic band dispersion with a sizable contribution of hydrogen 1s states. Our study thus feature the oxyhydrides as possible model polar superconducting systems, which may be utilizable for future magneto-electric devices.

description: Κατά τις πρώτες μεταπολεμικές δεκαετίες, η δραστηριοποίηση των γυναικών στο Λιβάδι, ήταν σχεδόν αποκλειστικά προσανατολισμένη στον "οικιακό χώρο", σε ασχολίες στενά συνυφασμένες με το "φυσικό" τους προορισμό, δηλαδή τη δημιουργία οικογένειας. Αυτός ο κατά φύλα καταμερισμός της εργασίας σε συνδυασμό με τις δομές της συγγένειας και της κοινότητας συνιστούσε ρυθμιστικό κανόνα στην κατασκευή της έμφυλης ταυτότητας. Στη σύγχρονη εποχή, η ατομική δράση των νέων γυναικών, με συνιστώσες τη συμμετοχή τους στη μέση ή ανώτερη εκπαίδευση και τις προοπτικές έμμισθης απασχόλησης, επιφέρει διαφορετικούς τρόπους βίωσης του εαυτού και του φύλου τους, με αποτέλεσμα στον ίδιο κοινωνικό πλαίσιο να συνυπάρχουν αλλά και να συγκρούονται πολλαπλές και διαφορετικές οπτικές της ταυτότητας. Ωστόσο, οι επιλογές αυτές δεν ακυρώνουν τις παραδοσιακές έμφυλες αντιλήψεις, αλλά τις μετασχηματίζουν με τρόπο ευέλικτο που εξασφαλίζει τη μακρά τους διάρκεια και συνάδει προς τον πολιτισμικό και όχι τον βιολογικό ορισμό του φύλου
description: Women's duties in Livadi during the first decades after the Second World War were domestically oriented. Women were almost entirely preoccupied with the household and the creation of family, since they were thought to embody the "natural" prospect of sexual reproduction. The dominant norm of male and female spheres of activity with regard to kinship and the structure of community encouraged women and men to follow one, and only one, idea of what is appropriate to their sex. In contemporary life, the individual practices of young women as a result of compulsory education and opportunities for paid work outside the domestic sphere have consequently produced a variation of gender roles and representations. Neverheless, different aspects of gender identifications do not invalidate the traditional set of ideas about men and women in married life, but tey transform them in an alternative way that ensures their long-standing existence as determinan factors of gender identity. In that case, it is clear that gender models are not biologically determinded but culturally constructed

description: When a bilayer of graphene is placed in a suitably configured field effect device, an asymmetry gap can be generated and the carrier concentration made different in each layer. This provides a tunable semiconducting gap, and the valence and the conductance band no longer meet at the two Dirac points of the graphene Brillouin zone. We calculate the optical conductivity of such a semiconductor with particular emphasis on the optical spectral weight redistribution brought about by changes in gap and chemical potential due to charging. We derive an algebraic formula for arbitrary value of the chemical potential for the case of the bilayer conductivity without a gap.

description: We present, for the first time, an \textit{ab initio} calculation of the individual up, down and strange quark helicity parton distribution functions for the proton. The calculation is performed within the twisted mass clover-improved fermion formulation of lattice QCD using one ensemble of dynamical up, down, strange and charm quarks with a pion mass of 260 MeV. The lattice matrix elements are non-perturbatively renormalized and the final results are presented in the $\overline{ \rm MS}$ scheme at a scale of 2 GeV. We give results on the $Δu^+(x)$ and $Δd^+(x)$, including disconnected quark loop contributions, as well as on the $Δs^+(x)$. For the latter we achieve unprecedented precision compared to the phenomenological estimates.

description: Bosonization predicts that the specific heat, C(T), of a one-dimensional interacting Fermi system is a sum of the specific heats of free collective charge and spin excitations, plus the term with the running backscattering amplitude which flows to zero logarithmically with decreasing T. We verify whether this result is reproduced in the g-ology model. Of specific interest are the anomalous terms in C(T) that depend on the bare backscattering amplitude. We show that these terms can be incorporated into a renormalized spin velocity. We do this by proving the equivalence of the results for C(T) obtained within the g-ology model and by bosonization with velocities obtained by the numerical solution of the Bethe-ansatz equations for the Hubbard model.

description: This research is to get information about the appreciation of motif block batik traditional melayu. It aimsto show the beauty found in the carvings and earnings on these motifs in terms of patterns and meaningsthat are produced. The investigation was conducted around the area of Kota Bharu, Kelantan. Theapproach of the researcher is qualitative which involves two materials namely secondary (text materials)and primary (artifacts). Batik is a symbol of the culture of the Malay community, the artistry of each pieceof cloth, has a specialty and uniqueness. The resulting block batik cloth begins with carved wood designedby the craftment on pieces of wood dyed with dyes and applied to the cloth. The beauty of the value ofbatik cloth lies in the motifs and manufacturing techniques that are applied to the surface of the cloth.According to JuhariAzmi , (2009) traditional design in Tanah Melayu was initially influenced by the valueand culture of art from outside the country [1]. Batik cloth illustrates and reflects the modesty of Malaywomen associated with the wearing of batik sarong cloth on the body. Every batik work that is producedand the method of wearing batik cloth has a symbolic and identity of Malay culture. Appreciation in thisconcept is an appreciation and assessment of the beauty and interpretation of motifs on batik blocks or theart of carving motifs on batik blocks. This study is about the appreciation of batik block design, wherebatik blocks are used as material in analyzing their content. In this investigation the reviewer uses thetheory of sociology of knowledge, it is to understand the carvings on batik blocks as well as therelationship with society and how this motif can be preserved. This study is expected to provideknowledge to the community and maintain Malay cultural arts from the loss technology that isincreasingly developing forward because the success of a nation depends on the greatness of the nation'scultural arts.

description: Continuous Glucose Monitoring (CGM) has emerged as a promising tool in managing glycemic control for patients with diabetes admitted to the Intensive Care Unit (ICU). This paper provides a comprehensive review of the potential benefits, challenges, and implications associated with CGM utilization in ICU settings for diabetes patients. The benefits of Continuous Glucose Monitoring (CGM) from the real-time measurement and monitoring of glucose levels, facilitating timely interventions in potential diabetes complications with the aim of maintaining patients at euglycemic levels. Thus, it allows for the design of personalized therapeutic strategies tailored to each patient, leading to improved glucose control and significant reduction in complications often observed in Type 2 diabetes. Despite the potential benefits, there are numerous challenges associated with CGM systems that need to be addressed. Furthermore, extensive training of healthcare professionals is required for the successful implementation of CGM technology. In conclusion, while further research is necessary to evaluate the cost-effectiveness and long-term implications of CGM implementation in the ICU setting, it is expected to play an increasingly vital role in personalized diabetes management strategies in the ICU, ultimately enhancing patient care and outcomes.

Moreover, I examine the concepts of invisibility and hypervisibility in oppressive technologies a lá the canonical double bind. Furthermore, I discuss what it means to call for diversity as a solution to algorithmic violence, and I critique dialectics of the fairness, accountability, and transparency community. I end by inviting you to envision and imagine the struggle to abolish algorithmic oppression by abolishing oppressive systems and shifting algorithmic development practices, including engaging our communities in scientific processes, centering marginalized communities in design, and consensual data and algorithmic practices.

Three-orbital continuous model for $1H$-type metallic transition-metal dichalcogenide monolayers

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We theoretically investigate the electronic states in monolayer NbSe$_2$ and develop continuous models to describe these states in Fermi pockets. In $1H$-type metallic transition-metal dichalcogenides(TMDCs), the Femi surface consists of three pockets enclosing the $Γ$, $K$, and $K'$ points. We reveal that the conventional effective model used for semiconducting TMDCs is not sufficient to describe the electronic states in metallic TMDCs and thus introduce a scheme to construct the effective model from the first-principles results. All models can be represented by $3\times3$ Hamiltonian and well reproduce electronic states around the Fermi energy in terms of the orbital composition and the phase factor. We also show that the $p$ orbitals in chalcogen atoms, which are ignored in the conventional $2\times2$ model, play a crucial role in metallic TMDCs. Although the aim of these models is to reproduce electronic states, they can well describe states near the high-symmetry points and the profile of Berry curvature in the wave vector space. The continuous model can be a handleable tool to describe the electronic states and to analyze the transport phenomena in metallic TMDCs.

The Riemann-Siegel formula and large scale computations of the Riemann zeta function
Creators: name: Pugh, Glendon Ralph
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a survey of the derivation and implementation of the Riemann-Siegel formula for computing values of Riemann's zeta function on the line s = 1/2 + it. The formula, devised by Riemann and later published by Siegel following study of Riemann's unpublished work, is the method of choice for both numerically verifying the Riemann Hypothesis and locating zeros on the critical line at large values of t. Simply stated, the Riemann Hypothesis is that all of the zeros of ζ(s) in the strip 0 < R(s) < 1 lie on the line R(s) = 1/2. Since Riemann made his conjecture in 1859, much work has been done towards developing efficient numerical techniques for verifying the hypothesis and possibly finding counter-examples. This thesis is meant to serve as a guide book for using Riemann-Siegel. It is mostly a distillation of work done in the field since Siegel's results published in the early 1930's. Computer programs and examples are included, and error bounds are discussed. The question of how and why Riemann-Siegel is used to verify the Riemann Hypothesis is examined, and a detailed Riemann Hypothesis verification example is illustrated. Finally, recent work in the field is noted. The derivation of the Riemann-Siegel formula for computing ζ(l/2 + it) is based on the saddle point method of evaluating integrals, and yields results of considerable accuracy in time t1/2. The saddle point method is an approximation technique which concentrates the "bulk" of an integral on a path through a point at which the modulus of the integrand is a maximum.

description: In adiabatic Cooper pair pumps, operated by means of gate voltage modulation only, the quantization of the pumped charge during a cycle is limited due to the quantum coherence of the macroscopic superconducting wave function. In this work we show that it is possible to obtain very accurate pumps in the non-adiabatic regime by a suitable choice of the shape of the gate voltage pulses. We determine the shape of these pulses by applying quantum optimal control theory to this problem. In the optimal case the error, with respect to the quantized value, can be as small as of the order of (10E-6)e: the error is reduced by up to five orders of magnitude with respect to the adiabatic pumping. In order to test the experimental feasibility of this approach we consider the effect of charge noise and the deformations of the optimal pulse shapes on the accuracy of the pump. Charge noise is assumed to be induced by random background charges in the substrate, responsible for the observed 1/f noise. Inaccuracies in the pulse shaping are described by assuming a finite bandwidth for the pulse generator. In realistic cases the error increases at most of one order of magnitude as compared to the optimal case. Our results are promising for the realization of accurate and fast superconducting pumps.

description: Within supersymmetric SU(5) GUT we suggest mechanisms for suppression of baryon number violating dimension five and six operators. The mechanism is based on the idea of split multiplets (i.e. quarks and leptons are not coming from a single GUT state) which is realized by an extension with additional vector-like matter. The construction naturally avoids wrong asymptotic relation $\hat{M}_D=\hat{M}_E$. Thus, the long standing problems of the minimal SUSY SU(5) GUT can be resolved. In a particular example of flavor structure and with additional ${\cal U}(1)\tm {\cal Z}_{3N}$ symmetry we demonstrate how the split multiplet mechanism works out. Namely, the considered model is compatible with successful gauge coupling unification and realistic fermion mass pattern. The nucleon decay rates are relatively suppressed and can be well compatible with current experimental bounds.

description: Construction of Section 19 of the Ashland-Alexandria Highway began in 1987. Because native soils have very low CBR values (1 to 3), it was decided to stabilize the soil subgrade with an application of 6% hydrated lime. The top 6 inches of the subgrade was to be stabilized. This process had not been previously used in Kentucky; and consequently, a research study was initiated to monitor this project. Objectives of the study were to monitor and document construction procedures, to determine the engineering characteristics of the treated subgrade through laboratory testing, and to report on the study findings. A substantial amount of field testing was conducted to confirm and supplement laboratory testing.  Conclusions drawn from the study were: the addition of hydrated lime to the clay soil produced a desirable end product in which all engineering characteristics of the subgrade were improved, the Special Note for this project did not provide sufficient detail for inspection and acceptance but was revised subsequent to this project, depth of treatment was significantly less than specified, and that lime stabilization can significantly increase the bearing capacity of clayey soil subgrades.  Ridges or transverse humps have developed in the pavement surface of Section 19. The ridges were not extensive or of notable magnitude until approximately four years after completion of Section 19. An investigation of the ridges indicated that swell of the underlying Crab Orchard Shale and possibly swell of the untreated clay subgrade produced sufficient pressure to crack the treated subgrade.

description: This thesis deals with  similarities between the fables of two notable literal features Aesops and Gulkhaniy’s work. In order to explain the reality of people’s lifestyles, dramas, hope  clearly, both utilized proverbs and  characterized animals in place of real people. Although he avoided using exact names for his characters, readers can easily comprehend that the key points. The authors were one of whose work affected positevely to the good ubringing of future generation and  profound part of textbooks in many secondary schools.  Besides having individual personality, the characters of their fables  interact feel and express a wide range of  emotions like people.In this thesis. I will investigate the similarities between the Zarbulmasal’s fables and Aesops’s fables and provide readers with clearly explained descriptions about them.

description: We propose a numerically efficient `adjoint' inverse design method to optimize a planar structure of dipole scatterers, to manipulate the radiation from an electric dipole emitter. Several examples are presented: modification of the near-field to provide a 3 fold enhancement in power emission; re-structuring the far-field radiation pattern to exhibit chosen directivity; and the design of a discrete `Luneburg lens'. Additionally, we develop a clear physical interpretation of the optimized structure, by extracting `eigen-polarizabilities' of the system. We find that large `eigen-polarizability' corresponds to a large collective response of the scatterers. This framework may find utility in wavefront shaping as well as in the design and characterisation of non-local metasurfaces.

description: The primary objective of this study was to investigate the feasibility of implementation of the crumb rubber technology in Kentucky. The impetus for this study was provided by the lntermodal Surface Transportation Efficiency Act of 1991 (ISTEA).  This study included an overview of existing literature on the subject from an implementation point of view for Kentucky's conditions. Upon completion of this phase of the study, guidelines were developed by the KTC research team and were submitted to the Transportation Cabinet for field implementation of the crumb rubber modifier (CAM) technology in Kentucky. From the ease of implementation point of view, the Cabinet opted to build a field trial section using the "wet process" which utilized a fine ground rubber (80 mesh) material. The rationale for this decision was based upon the fact that the fine ground CAM mix closely resembles the polymer modified HMA, and that both the Cabinet and Kentucky contractors have an extensive amount of experience with polymer modified asphalt.  In July 1993, a field trial project was constructed on a portion of the US 421, Franklin County, Kentucky. The project involved milling of nominally one inch of the wearing surface followed up by a nominally one-inch overlay. The four-lane trial project (two lanes in each direction) was divided into two approximately half-mile sections. This allowed for a comparison of performance between the CAM hot mix asphalt (HMA) and the conventional HMA.  In summary, the trial implementation of the CAM technology in Kentucky proved to be a success. The 80-mesh fine ground rubber at 7.5% by weight of asphalt cement provided a material similar to polymer modified asphalt. Construction of the field project was possible with existing specifications and practices in Kentucky. The non-intrusive nature of the fine ground technology was most desirable from the ease of implementation point of view.

description: The standard model of Mn doping in GaAs is subjected to a coherent potential approximation (CPA) treatment. Transport coefficients are evaluated within the linear response Kubo formalism. Both normal (NHE) and anomalous contributions (AHE) to the Hall effect are examined. We use a simple model density of states to describe the undoped valence band. The CPA bandstructure evolves into a spin split band caused by the $p-d$ exchange scattering with Mn dopants. This gives rise to a strong magnetoresistance, which decreases sharply with temperature. The temperature ($T$) dependence of the resistance is due to spin disorder scattering (increasing with $T$), CPA bandstructure renormalization and charged impurity scattering (decreasing with $T$). The calculated transport coefficients are discussed in relation to experiment, with a view of assessing the overall trends and deciding whether the model describes the right physics. This does indeed appear to be case, bearing in mind that the hopping limit needs to be treated separately, as it cannot be described within the band CPA.

description: Selective interception of objects in unknown environment autonomously by UAVs is an interesting problem. In this work, vision based interception is carried out. This problem is a part of challenge 1 of Mohammed Bin Zayed International Robotic Challenge, 2020, where, balloons are kept at five random locations for the UAVs to autonomously explore, detect, approach and intercept. The problem requires a different formulation to execute compared to the normal interception problems in literature. This work details the different aspect of this problem from vision to manipulator design. The frame work is implemented on hardware using Robot Operating System (ROS) communication architecture.

description: We establish a version of the bottleneck conjecture, which in turn implies a partial solution to the Mahler conjecture on the product $v(K) = (\Vol K)(\Vol K^\circ)$ of the volume of a symmetric convex body $K \in \R^n$ and its polar body $K^\circ$. The Mahler conjecture asserts that the Mahler volume $v(K)$ is minimized (non-uniquely) when $K$ is an $n$-cube. The bottleneck conjecture (in its least general form) asserts that the volume of a certain domain $K^\diamond \subseteq K \times K^\circ$ is minimized when $K$ is an ellipsoid. It implies the Mahler conjecture up to a factor of $(π/4)^n γ_n$, where $γ_n$ is a monotonic factor that begins at $4/π$ and converges to $\sqrt{2}$. This strengthens a result of Bourgain and Milman, who showed that there is a constant $c$ such that the Mahler conjecture is true up to a factor of $c^n$. The proof uses a version of the Gauss linking integral to obtain a constant lower bound on $\Vol K^\diamond$, with equality when $K$ is an ellipsoid. It applies to a more general conjecture concerning the join of any two necks of the pseudospheres of an indefinite inner product space. Because the calculations are similar, we will also analyze traditional Gauss linking integrals in the sphere $S^{n-1}$ and in hyperbolic space $H^{n-1}$.

description: We present refined values for the physical parameters of transiting exoplanets, based on a self-consistent and uniform analysis of transit light curves and the observable properties of the host stars. Previously it has been difficult to interpret the ensemble properties of transiting exoplanets, because of the widely different methodologies that have been applied in individual cases. Furthermore, previous studies often ignored an important constraint on the mean stellar density that can be derived directly from the light curve. The main contributions of this work are 1) a critical compilation and error assessment of all reported values for the effective temperature and metallicity of the host stars; 2) the application of a consistent methodology and treatment of errors in modeling the transit light curves; and 3) more accurate estimates of the stellar mass and radius based on stellar evolution models, incorporating the photometric constraint on the stellar density. We use our results to revisit some previously proposed patterns and correlations within the ensemble. We confirm the mass-period correlation, and we find evidence for a new pattern within the scatter about this correlation: planets around metal-poor stars are more massive than those around metal-rich stars at a given orbital period. Likewise, we confirm the proposed dichotomy of planets according to their Safronov number, and we find evidence that the systems with small Safronov numbers are more metal-rich on average. Finally, we confirm the trend that led to the suggestion that higher-metallicity stars harbor planets with a greater heavy-element content.

description: The equilibrium and fluctuations of an ideal gas in a rigid container are studied by every student of statistical mechanics. Here we study the less well-known case when the box is floating freely; in particular we determine the fluctuations of the box in velocity and position due to interactions with the gas it contains. This system is a toy model for the fluctuations in velocity and position of a black hole surrounded by stars at the center of a galaxy. These fluctuations may be observable in nearby galaxies.
