description: The non-centrosymmetric semiconductors BiTeX (X = Cl, Br, I) show large Rashba-type spin-orbit splittings in their electronic structure making them candidate materials for spin-based electronics. However, BiTeI(0001) single crystal surfaces usually consist of stacking-fault-induced domains of Te and I terminations implying a spatially inhomogeneous electronic structure. Here we combine scanning tunneling microscopy (STM), photoelectron spectroscopy (ARPES, XPS) and density functional theory (DFT) calculations to systematically investigate the structural and electronic properties of BiTeX(0001) surfaces. For X = Cl, Br we observe macroscopic single-terminated surfaces. We discuss chemical characteristics among the three materials in terms of bonding character, surface electronic structure, and surface morphology.

description: We present a study of the electronic and optical bandgap in layered TiS3, an almost unexplored semiconductor that has attracted recent attention because of its large carrier mobility and inplane anisotropic properties, to determine its exciton binding energy. We combine scanning tunneling spectroscopy and photoelectrochemical measurements with random phase approximation and Bethe-Salpeter equation calculations to obtain the electronic and optical bandgaps and thus the exciton binding energy. We find experimental values for the electronic bandgap, optical bandgap and exciton binding energy of 1.2 eV, 1.07 eV and 130 meV, respectively, and 1.15 eV, 1.05 eV and 100 meV for the corresponding theoretical results. The exciton binding energy is orders of magnitude larger than that of common semiconductors and comparable to bulk transition metal dichalcogenides, making TiS3 ribbons a highly interesting material for optoelectronic applications and for studying excitonic phenomena even at room temperature.

description: Web intelligence can be considered as a subset of Artificial Intelligence. It uses existing data in web to produce new data, knowledge and wisdom to support decision making and new predictions for web users. Artificial Intelligence is ever changing and evolving field of computer science and it is extensively used in wide array of web based business applications. Although it is used substantially in web based systems in developed countries, it is not examined whether it is being substantially used in Sri Lanka. Every Sri Lankan citizen depends on Public Service more or less throughout his/ her life time and at least more than 3 times: at birth, marriage and death. So providing most of these services to its citizen, Sri Lankan Government uses more or less of its country web portal. This paper presents a model to evaluate web intelligence capability based on weight to key functionalities with respect to web intelligence. The government websites were checked by the proposed criteria to show the potential of using web intelligent technology to provide website based services. The result indicates that the use of web intelligence techniques openly and publicly to provide web based services through government web portal to its citizens is not satisfactory. It also indicates that lack of using the technologies pertaining to web intelligence in the public service web hinders the most of the advantages that citizen and government can gain from such technological involvement.

Beautiful Arrogance
Creators: name: Hernandez, Matthew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: My aim in this thesis is to examine how we understand arrogance, what occurs when it is attributed to oppressed peoples, and how our evaluation of arrogance changes in contexts of oppression. I argue that arrogance is an attitude where one views oneself as more important than others, which is offensive from a moral point of view. However, members of oppressed groups, when engaging in protest, are often called arrogant despite not demonstrating this attitude. I present two explanations for why viewers may think protesters are arrogant and put forth a further explanation of how this practice reflects and reinforces oppressions. Finally, I will argue that when members of oppressed groups are arrogant, their arrogance can be a sign of excess basal self-respect, which is inspiring for others. I will call this beautiful arrogance, which, all things considered, is good and can be utilized as a form of resistance.

Preventing Expulsion And Suspension through Policy Alignment and Cohesion (PEASPAC): Linkages between Federal Guidance, State CCDF plans, State Child Care Licensing, State QRIS, and State Pre-K Policies
Creators: name: Buell, Martha
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Public Affairs, Public Policy and Public Administration
subject: Education
subject: Social and Behavioral Sciences
subject: Early Childhood Education

description: The proposed project will provide an analysis of the alignment and cohesion between the federal CCDF policy guidance and state level policy actors. Specifically, the project will assess the vertical alignment of state CCDF plans with the federal guidance on key policy components for preventing exclusion through suspension and expulsion, vertical alignment of the state CCDF plan with state child care licensing policy, state Quality Rating and Improvement Systems (QRIS) standards, and state Pre-K policies; and horizontal cohesion across the state level units. Nationally, studies have demonstrated that suspension and expulsion are approaches to discipline that are overly applied to boys, children of color and children with disabilities, with devastating consequences. Thus, in 2016, the CCDBG state plan template changed with the addition of section 2.5.6. The addition reads, “Describe the Lead Agency’s policies to prevent the suspension and expulsion of children from birth to age 5 in child care and other early childhood programs receiving CCDF funds (98.16(ee) ), including how those policies are shared with families, providers, and the general public.” Despite this guidance document, how states addressed this new section of their state plans has proved to vary widely. Furthermore, while the state plans provide guidance for spending federal funds, how these plans will be actualized depends on the policies in place in up to three different state-level policy units- child care licensing, QRIS and state Pre-K., creating a complex policy context where policy alignment and coherence will be key to meeting the federal goal of reduced suspension and expulsion. Therefore, the intent of this secondary data analysis is threefold: 1) Analyze state CCDF plans according to the policy statements offered by HHS/ACF regarding key policy components that support eliminating suspension and expulsion; 2) Assess the vertical alignment between the state CCDF plan and state child care licensing policy, state QRIS policy and state pre-K policy; 3) Assess and rate the cohesion of state plan and state-level child care licensing policy, state QRIS policy and state Pre-K/preschool policy regarding discipline practices including exclusionary discipline- suspension and expulsion

Modulated nematic structures induced by chirality and steric polarization

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: What kind of one-dimensional modulated nematic structures (ODMNS) can form nonchiral and chiral bent-core and dimeric materials? Here, using Landau-deGennes theory of nematics, extended to account for molecular steric polarization, we study a possibility of formation of ODMNS, both in nonchiral and intrinsically chiral liquid crystalline materials. Besides nematic and cholesteric phases, we find four bulk ODMNS for nonchiral materials, two of which have not been reported so far. These new structures are longitudinal ($N_{LP}$) and transverse ($N_{TP}$) periodic waves where the polarization field being periodic in one dimension stays parallel and perpendicular, respectively, to the wave vector. The other two phases have all characteristic features of the twist-bend nematic phase ($N_{TB}$) and the splay-bend nematic phase ($N_{SB}$), but their fine structure appears more complex than that considered so far. The presence of molecular chirality converts nonchiral $N_{TP}$ and $N_{SB}$ into new $N_{TB}$ phases. Interestingly, the nonchiral $N_{LP}$ phase can stay stable even in the presence of intrinsic molecular chirality. Exemplary phase diagrams provide further insights into the relative stability of these new modulated nematic structures.

description: The lifetimes of the lower-lying vibrational states of ultralong-range strontium Rydberg molecules comprising one ground-state 5s2 1S0 atom and one Rydberg atom in the 5s38s 3S1 state are reported. The molecules are created in an ultracold gas held in an optical dipole trap and their numbers determined using field ionization, the product electrons being detected by a microchannel plate. The measurements show that, in marked contrast to earlier measurements involving rubidium Rydberg molecules, the lifetimes of the low-lying molecular vibrational states are very similar to those of the parent Rydberg atoms. This results because the strong p-wave resonance in low-energy electronrubidium scattering, which plays an important role in determining the molecular lifetimes, is not present for strontium. The absence of this resonance offers advantages for experiments involving strontium Rydberg atoms as impurities in quantum gases and for testing theories of molecular formation and decay.

description: We present an extensive Monte Carlo study on light transport in optically thin slabs, addressing both axial and transverse propagation. We completely characterize the so-called ballistic-to-diffusive transition, notably in terms of the spatial variance of the transmitted/reflected profile. We test the validity of the prediction cast by diffusion theory, that the spatial variance should grow independently of absorption and, to a first approximation, of the sample thickness and refractive index contrast. Based on a large set of simulated data, we build a freely available look-up table routine allowing reliable and precise determination of the microscopic transport parameters starting from robust observables which are independent of absolute intensity measurements. We also present the Monte Carlo software package that was developed for the purpose of this study.

Στο πρώτο κεφάλαιο γίνεται αναφορά στην ανάπτυξη του δικτύου από την πρώτη μέχρι την πέμπτη γενιά. Τα δίκτυα 1G αποτελούν την εισαγωγή στα κυψελοειδή συστήματα, με δυνατότητα να μεταδίδουν μόνο φωνητικά σήματα με αναλογικό τρόπο. Η ανάγκη για καλύτερη ποιότητα, χωρητικότητα και κάλυψη συστήματος οδηγεί στα δίκτυα 2G που μπορούν πλέον εκτός από φωνή να μεταδίδουν και δεδομένα με ασφαλείς συνθήκες και υψηλότερους ρυθμούς. Οι αυξημένες απαιτήσεις των χρηστών οδηγούν στην ανάγκη για πιο υψηλές ταχύτητες και στην δημιουργία των δικτύων 3G τα οποία είναι ικανά να μεταδώσουν φωνή, δεδομένα και αρχεία πολυμέσων. Η εξέλιξη αύτη αποτελεί κομβικό σημείο για την ανάπτυξη των δικτύων καθώς η καθημερινότητα πλέον βασίζεται στην περιήγηση στο δίκτυο και τη χρήση διάφορων εφαρμογών. Η ταχύτητα μετάδοσης εξακολουθεί να αυξάνεται και αυτό οδηγεί στην τέταρτη γενιά δικτύων που σαν βασικό στόχο έχει την βελτίωση της ποιότητας παροχής υπηρεσιών και την δημιουργία εφοδίων για τις εφαρμογές που θα ακολουθήσουν. Κλείνοντας το κεφάλαιο γίνεται αναφορά στην εξέλιξη του δικτύου στην πέμπτη γενιά που παρέχει μεγαλύτερη χωρητικότητα, μεγαλύτερο ρυθμό μετάδοσης, μικρότερη καθυστέρηση, μαζική συνδεσιμότητα συσκευών και μειωμένο κόστος. Στο δεύτερο κεφάλαιο περιγράφονται τα βασικά χαρακτηριστικά του δικτύου 5G και η αρχιτεκτονική που χρησιμοποιήθηκε για την δημιουργία του. Το κεφάλαιο κλείνει με τις τεχνολογίες που χρησιμοποιούνται στο δίκτυο 5G όπως η διπλή συνδεσιμότητα LNE-NR, NFV,SDN, Multi-access edge computing και τα ασύρματα συστήματα πολλαπλών εισόδων- εξόδων. Στο τρίτο κεφάλαιο αναλύονται διάφορες περιπτώσεις χρήσης του 5G. Η πρώτη περίπτωση χρήσης αφορά τις έξυπνες πόλεις. Μέσω της τεχνολογίας των δικτύων πέμπτης γενιάς θα υπάρχουν σημαντικές μεταβολές στην ενέργεια, την υγειονομική περίθαλψη και την βιομηχανία. Στην συνέχεια γίνεται αναφορά στην ανάπτυξη των μεταφορών. Επιπρόσθετα το 5G δίκτυο φέρνει ριζοσπαστικές αλλαγές και στην ασφάλεια του κοινωνικού συνόλου μέσω των ρομποτ περιπολίας. Έπειτα περιγράφεται πώς το 5G θα επηρεάσει τον τομέα της εκπαίδευσης και τέλος οι αλλαγές που προβλέπεται να υπάρξουν στο χώρο των διαδικτυακών παιχνιδιών. Τέλος, γίνεται αναφορά στην σημαντικότητα της χρήσης του 5G στην Ελλάδα καθώς και τα συμπεράσματα που προέκυψαν από την έρευνα.

description: Zurzeit befinden sich Familien- und Gleichstellungspolitik in Deutschland häufig in einem Konkurrenzverhältnis zueinander, obwohl und gerade weil es große Überschneidungsbereiche zwischen ihnen gibt, z.B. in Bezug auf die Verbindung von Familie und Erwerbstätigkeit. Dadurch werden Ungleichheitsbeziehungen zwischen Männern und Frauen weiter verstetigt, wie der Beitrag anhand der Dimensionen Geschlecht, Elternschaft und Bildung zeigt. Dabei stellt sich heraus, dass eine deutlich engere Verzahnung von Familien- und Gleichstellungspolitik zu einer gerechteren Arbeitsteilung einerseits und zum Abbau von Polarisierungstendenzen bei der Familienbildung andererseits führen kann.

The effects of exogenous orienting on sustained endogenous attention
Creators: name: Bholah, Prerna
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: In this study, event-related potentials were used to investigate the interactions between sustained endogenous attention and exogenous orienting by varying the degrees to which they are recruited within the same trial. Participants sustained attention to a specified visual field throughout a block, while performing a discrimination task in a within-subjects design in two different sessions: (1) strong endogenous-weak exogenous condition (high target predictability and dim cue) and (2) weak endogenous-strong exogenous condition (low target predictability and bright cue). Behavioral results showed interactions between the two attentional systems across all levels of engagement. The event-related P1 component was dominated by exogenous attention with interactions only in the strong endogenous condition. The P3 component was mainly modulated by sustained endogenous attention. These data provide new electrophysiological evidence that the degree of engagement of sustained endogenous attention and exogenous attention affect the level and type of interaction at multiple stages of processing.

description: Light diffusion is usually associated with thick, opaque media. Indeed, multiple scattering is necessary for the onset of the diffusive regime and such condition is generally not met in almost transparent media. Nonetheless, at long enough times, transport in an infinite thin slab is still determined by a multiple scattering process whose complete characterization is lacking. In this paper we show that, after a short transient, the mean square width of the transmitted intensity still exhibits a simple linear increase with time as predicted by diffusion theory, even at optical thickness as low as one. Interestingly, such linear growth is predicted not to depend neither on the slab thickness nor on its refractive index contrast, yet the accuracy of this simple approximation in the ballistic-to-diffusive regime hasn't been investigated so far. By means of Monte Carlo simulations, we find clear evidence that boundary conditions play an active role in redefining the very asymptotic value of the diffusion coefficient by directly modifying the statistical distributions underlying light transport in such media. In this respect, we demonstrate the need to distinguish between a set of intrinsic and effective transport parameters, whose relation and interplay with boundary conditions remains to be fully understood.

description: In this work we present a new view on the thermodynamics of black holes introducing effects of irreversibility by employing thermodynamic optimization and finite-time thermodynamics. These questions are of importance both in physics and in engineering, combining standard thermodynamics with optimal control theory in order to find optimal protocols and bounds for realistic processes without assuming anything about the microphysics involved. We find general bounds on the maximum work and the efficiency of thermodynamic processes involving black holes that can be derived exclusively from the knowledge of thermodynamic relations at equilibrium. Since these new bounds consider the finite duration of the processes, they are more realistic and stringent than their reversible counterparts. To illustrate our arguments, we consider in detail the thermodynamic optimization of a Penrose process, i.e. the problem of finding the least dissipative process extracting all the angular momentum from a Kerr black hole in finite time. We discuss the relevance of our results for real astrophysical phenomena, for the comparison with laboratory black holes analogues and for other theoretical aspects of black hole thermodynamics.

Finite lives and infinite ends: an account of imperfect obligations to future generations
Creators: name: Falkenberg, Dana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Rights-based accounts of obligations to future generations suffer from a number of theoretical difficulties, most notably the non-identity problem. A more fruitful way of understanding these obligations (if, indeed, there are any) is through the notion of imperfect obligations. Imperfect obligations are actions that are owed to others even when those others lack a corresponding right to demand those actions of us. One way of establishing that we do indeed have obligations of this nature to future generations can be illustrated by the incoherence of willing a principle of indifference toward future generations. Because we are finite rather than self-sufficient beings, we must rely on the cooperation of future generations in order to have our current projects succeed.

Galaxy interactions in the Hickson Compact Group 88
Creators: name: Brosch, Noah
Publisher: name: arXiv
Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: I present observations of the Hickson Compact Group 88 (HCG88) obtained during the commissioning of a new 28-inch telescope at the Wise Observatory. This galaxy group was advertised to be non-interacting, or to be in a very early interaction stage, but this is not the case. The observations reported here were done using a "luminance" filter, essentially a very broad R filter, reaching a low surface brightness level of about 26 mag per square arcsec. Additional observations were obtained in a narrow spectral band approximately centered on the rest-frame H-alpha line from the group. Contrary to previous studies, my observations show that at least two of the major galaxies have had significant interactions in the past, although probably not between themselves. I report the discovery of a faint extended tail emerging from the brightest of the group galaxies, severe isophote twisting and possible outer shells around another galaxy, and map the HII regions in all the galaxies.

Toward a simultaneous description of $R_{AA}$ and $v_2$ for heavy quarks

description: The two key observables related to heavy quarks that have been measured in RHIC and LHC energies are the nuclear suppression factor $R_{AA}$ and the elliptic flow $v_2$. Simultaneous description of these two observables is a top challenge for all the existing models. We have highlighted how a consistent combination of four ingredients i.e the temperature dependence of the energy loss, full solution of the Boltzmann collision integral for the momentum evolution of heavy quark, hadronization by coalescence, then the hadronic rescattering, responsible to address a large part of such a puzzle. We have considered four different models to evaluate the temperature dependence of drag coefficients of the heavy quark in QGP. All these four different models are set to reproduce the same $R_{AA}$ as of the experiments. We have shown that for the same $R_{AA}$, the $v_2$ could be quite different depending on the interaction dynamics as well as other ingredients.

description: We present a tele-immersive system that enables people to interact with each other in a virtual world using body gestures in addition to verbal communication. Beyond the obvious applications, including general online conversations and gaming, we hypothesize that our proposed system would be particularly beneficial to education by offering rich visual contents and interactivity. One distinct feature is the integration of egocentric pose recognition that allows participants to use their gestures to demonstrate and manipulate virtual objects simultaneously. This functionality enables the instructor to ef- fectively and efficiently explain and illustrate complex concepts or sophisticated problems in an intuitive manner. The highly interactive and flexible environment can capture and sustain more student attention than the traditional classroom setting and, thus, delivers a compelling experience to the students. Our main focus here is to investigate possible solutions for the system design and implementation and devise strategies for fast, efficient computation suitable for visual data processing and network transmission. We describe the technique and experiments in details and provide quantitative performance results, demonstrating our system can be run comfortably and reliably for different application scenarios. Our preliminary results are promising and demonstrate the potential for more compelling directions in cyberlearning.
