description: P.W. Anderson proposed the concept of complexity in order to describe the emergence and growth of macroscopic collective patterns out of the simple interactions of many microscopic agents. In the physical sciences this paradigm was implemented systematically and confirmed repeatedly by successful confrontation with reality. In the social sciences however, the possibilities to stage experiments to validate it are limited. During the 90's a series of dramatic political and economic events have provided the opportunity to do so. We exploit the resulting empirical evidence to validate a simple agent based alternative to the classical logistic dynamics. The post-liberalization empirical data from Poland confirm the theoretical prediction that the dynamics is dominated by singular rare events which insure the resilience and adaptability of the system. We have shown that growth is led by few singular "growth centers" (Figure 1), that initially developed at a tremendous rate (Figure3), followed by a diffusion process to the rest of the country and leading to a positive growth rate uniform across the counties. In addition to the interdisciplinary unifying potential of our generic formal approach, the present work reveals the strong causal ties between the "softer" social conditions and their "hard" economic consequences.

description: Electric Vehicle (EV) has become a preferable choice in the modern transportation system due to its environmental and energy sustainability. However, in many large cities, EV drivers often fail to find the proper spots for charging, because of the limited charging infrastructures and the spatiotemporally unbalanced charging demands. Indeed, the recent emergence of deep reinforcement learning provides great potential to improve the charging experience from various aspects over a long-term horizon. In this paper, we propose a framework, named Multi-Agent Spatio-Temporal Reinforcement Learning (Master), for intelligently recommending public accessible charging stations by jointly considering various long-term spatiotemporal factors. Specifically, by regarding each charging station as an individual agent, we formulate this problem as a multi-objective multi-agent reinforcement learning task. We first develop a multi-agent actor-critic framework with the centralized attentive critic to coordinate the recommendation between geo-distributed agents. Moreover, to quantify the influence of future potential charging competition, we introduce a delayed access strategy to exploit the knowledge of future charging competition during training. After that, to effectively optimize multiple learning objectives, we extend the centralized attentive critic to multi-critics and develop a dynamic gradient re-weighting strategy to adaptively guide the optimization direction. Finally, extensive experiments on two real-world datasets demonstrate that Master achieves the best comprehensive performance compared with nine baseline approaches.

description: Magnetic-field-induced phase transitions were studied with a two-dimensional electron AlGaAs/GaAs system. The temperature-driven flow diagram shows the features of the $Γ$(2) modular symmetry, which includes distorted flowlines and shiftted critical point. The deviation of the critical conductivities is attributed to a small but resolved spin splitting, which reduces the symmetry in Landau quantization. [B. P. Dolan, Phys. Rev. B 62, 10278.] Universal scaling is found under the reduction of the modular symmetry. It is also shown that the Hall conductivity could still be governed by the scaling law when the semicircle law and the scaling on the longitudinal conductivity are invalid. *corresponding author:yhchang@phys.ntu.edu.tw

description: Buildings account for about 40% of energy consumption in the European Union (EU) and 36% of greenhouse gas emissions, making them the largest energy consumer in Europe. Energy performance contracting (EPC) as a tool to improve the energy efficiency of buildings can accelerate investments in cost-effective energy conservation measures (ECM) for existing buildings. However, there are many risks and barriers that can slow the adoption of EPC, such as the complexity of the process or the uncertainty of building performance after retrofit. The International Performance Measurement and Verification Protocol (IPMVP®), originally developed to encourage investment in energy and water efficiency, energy management, and renewable energy projects, has the potential to reduce some of the EPC barriers. However, due to limited and uncertain information about existing buildings, applying this measurement and verification protocol to retrofit projects is often complex and requires the use of novel building simulation tools. To address the challenges of applying IPMVP® in building retrofit projects, promote the adoption of EPC, and reduce greenhouse gas emissions in the EU, the research presented here developed ModSCO, a web application that supports a systematic assessment of energy performance using a novel Reduced Order Model (ROM) that can be used for (i) systematic quantification of energy savings achieved by ECMs (avoided energy consumption) and (ii) direct estimation of energy savings by exploring different building envelope retrofit scenarios. This thesis begins with a review of Energy Performance Contracting, followed by an research of the methodology based on ROM, which was chosen to overcome the EPC barriers. The thesis proceeds to describe the Reduced Order Grey Box Model (ROM), which serves as the core of ModSCO, the tool facilitating the estimation of energy savings in energy efficiency projects. A number of case studies are then discussed to demonstrate the accuracy and benefits of using the ROM as a novel method for estimating energy savings in building retrofits. Next, a description of the ModSCO web application and thus the front-end of ROM is presented along with a case study. Finally, the benefits derived from the research, the results and future work are discussed.

description: We study the possibility to use line-intensity mapping (LIM) to seek photons from the radiative decay of neutrinos in the cosmic neutrino background. The Standard Model prediction for the rate for these decays is extremely small, but it can be enhanced if new physics increases the neutrino electromagnetic moments. The decay photons will appear as an interloper of astrophysical spectral lines. We propose that the neutrino-decay line can be identified with anisotropies in LIM clustering and also with the voxel intensity distribution. Ongoing and future LIM experiments will have -- depending on the neutrino hierarchy, transition and experiment considered -- a sensitivity to an effective electromagnetic transition moment $\sim 10^{-12}\, -\,10^{-8}\, (m_ic^2/{0.1 \rm eV})^{3/2}μ_{\rm B}$, where $m_i$ is the mass of the decaying neutrino and $μ_{\rm B}$ is the Bohr magneton. This will be significantly more sensitive than cosmic microwave background spectral distortions, and it will be competitive with stellar cooling studies. As a byproduct, we also report an analytic form of the one-point probability distribution function for neutrino-density fluctuations, obtained from the Quijote simulations using symbolic regression.

description: Gravitational waves provide a unique and powerful opportunity to constrain the dynamics in the interior of proto-neutron stars during core collapse supernovae. Convective motions play an important role in generating neutron stars magnetic fields, which could explain magnetar formation in the presence of fast rotation. We compute the gravitational wave emission from proto-neutron star convection and its associated dynamo, by post-processing three-dimensional MHD simulations of a model restricted to the convective zone in the anelastic approximation. We consider two different proto-neutron star structures representative of early times (with a convective layer) and late times (when the star is almost entirely convective). In the slow rotation regime, the gravitational wave emission follows a broad spectrum peaking at about three times the turnover frequency. In this regime, the inclusion of magnetic fields slightly decreases the amplitude without changing the spectrum significantly compared to a non-magnetised simulation. Fast rotation changes both the amplitude and spectrum dramatically. The amplitude is increased by a factor of up to a few thousands. The spectrum is characterized by several peaks associated to inertial modes, whose frequency scales with the rotation frequency. Using simple physical arguments, we derive scalings that reproduce quantitatively several aspects of these numerical results. We also observe an excess of low-frequency gravitational waves, which appears at the transition to a strong field dynamo characterized by a strong axisymmetric toroidal magnetic field. This signature of dynamo action could be used to constrain the dynamo efficiency in a proto-neutron star with future gravitational wave detections.

description: Contemporary organizations are currently operating in a constantly changing environment where competition is relentlessly increasing. Hence, it is essential for organizations to be able to adapt to those changes in order to recruit and select the right candidate so they could be perceived as a competitive advantage. That is why, the purpose of this study is to analyse the phenomenon of Human Resources Management and Gamification, and then to examine the influence that Gamification has on Recruitment and Selection. In particular, it was examined what the candidate were thinking for the traditional methods of Selection, psychometric tests, in comparison with the modern Selection methods, Gamification, and to what degree do they affect the Organizational Attractiveness and the Job Acceptance Intention. Firstly, in order to understand the used terms in this study a literature review was carried out, and a research gap was spotted. This gap led to the development of two hypotheses. For this project a quantitative research method was used with 2 questionnaires and a Gamified application. The data analysis was executed with the statistical tool SPSS version 24. In total, 91 responses were collected which concluded that even though there was no difference between the 2 Selection methods and the Organizational Attractiveness and the Job Acceptance Intention, they tend to confirm the hypotheses

The conceptual approach of the aforementioned provision is initially attempted, followed by the presentation of all the amendments the article has undergonefrom its original form until nowadays. Subsequently, a brief parallel takes place, between this article and the provisions of Art. 315 of Greek Code of Civil Procedure, which regards the correction of judicial decisions in which an error has been committed, butwhichdoesnotconcernthesubstanceofthecase. The author then analyzes the individual provisions of article 18 under which the manifest error should be out-of-court corrected, at the request of the holder of a legitimate interest or of its own motion by the Head of the Cadastral Office.A corresponding thematic case is given. The aforementioned chapter is followed by analysis of the judicial resolution of manifest errors, as defined in article 18 (2) of Law 2664/1998, in conjunction with the provisions 13 (2), 16 (5) of Law 2664/1998 and the provision of article 791 (2-5) of the Greek Code of Civil Procedure. A corresponding thematic case is given. In conclusion, the provisions of article 18 shall be paralleled with those laid down in article 6 (3, 8) of Law 2664/1998

description: Recently, query based deep networks catch lots of attention owing to their end-to-end pipeline and competitive results on several fundamental computer vision tasks, such as object detection, semantic segmentation, and instance segmentation. However, how to establish a query based video instance segmentation (VIS) framework with elegant architecture and strong performance remains to be settled. In this paper, we present \textbf{QueryTrack} (i.e., tracking instances as queries), a unified query based VIS framework fully leveraging the intrinsic one-to-one correspondence between instances and queries in QueryInst. The proposed method obtains 52.7 / 52.3 AP on YouTube-VIS-2019 / 2021 datasets, which wins the 2-nd place in the YouTube-VIS Challenge at CVPR 2021 \textbf{with a single online end-to-end model, single scale testing \& modest amount of training data}. We also provide QueryTrack-ResNet-50 baseline results on YouTube-VIS-2021 val set as references for the VIS community.

description: We examine single-frequency optical schemes for species-selective trapping of ultracold alkali-metal atoms. Independently addressing the elements of a binary mixture enables the creation of an optical lattice for one atomic species with little or no effect on the other. We analyze a "tune-in" scheme, using near-resonant detuning to create a stronger potential for one specific element. A "tune-out" scheme is also developed, in which the trapping wavelength is chosen to lie between two strong transitions of an alkali-metal atom such that the induced dipole moment is zero for that species but is nonzero for any other. We compare these schemes by examining the trap depths and heating rates associated with both. We find that the tune-in scheme is preferable for Li-Na, Li-K, and K-Na mixtures, while the tune-out scheme is preferable for Li-Cs, K-Rb, Rb-Cs, K-Cs and 39K-40K mixtures. Several applications of species-selective optical lattices are explored, including the creation of a lattice for a single species in the presence of a phononlike background, the tuning of relative effective mass, and the isothermal increase of phase space density.

description: Ο ρυθμός ανάπτυξης ροπής (ΡΑΡ) αποτελεί ένα χρήσιμο εργαλείο για την αξιολόγηση της εκρηκτικής δύναμης. Ένας από τους παράγοντες που επηρεάζεται ο ΡΑΡ είναι η δύναμη, η οποία μπορεί να αυξηθεί μέσω προπόνησης, αν και κάτι τέτοιο δεν έχει μελετηθεί σε επίπεδο μηχανισμών για την παιδική ηλικία. Με τη συγκεκριμένη έρευνα, μελετήθηκε η επίδραση της χρόνιας προπόνησης στη δύναμη και τον ΡΑΡ σε αγόρια προεφηβικής ηλικίας. Στην εργασία έλαβαν μέρος επίλεκτοι αθλητές ποδοσφαίρου (n=15, ηλικίας: 10.03±0.56 έτη) και προέφηβα αγόρια που ασκούνταν μόνο στο μάθημα φυσικής αγωγής στο σχολείο (n=15, ηλικίας: 9.73±0.38 έτη). Οι εξεταζόμενοι αξιολογήθηκαν στη μέγιστη ισομετρική έκταση του γόνατος και η ανάλυση περιελάμβανε τον ΡΑΡ, το ηλεκτρομυογράφημα εκτεινόντων και καμπτήρων μυών του γόνατος και τη συχνότητα του ηλεκτρομυογραφήματος για τα πρώτα 30, 50, 100, και 200 ms μετά την έναρξη της σύσπασης. Τα αποτελέσματα έδειξαν υψηλότερες τιμές για τα προπονημένα παιδιά σε σχέση με τα απροπόνητα, στη μέγιστη ισομετρική ροπή, στον μέγιστο ΡΑΡ και στον ΡΑΡ στα 0-50, 0-100, και 0-200 ms, και στη συχνότητα ενεργοποίησης του έσω πλατύ μυός. Συμπερασματικά, η χρόνια προπόνηση σε αθλητές ποδοσφαίρου παιδικής ηλικίας επιφέρει προσαρμογές στη δύναμη και ΡΑΡ, που αποδίδονται σε νευρικούς παράγοντες όπως η συχνότητα ενεργοποίησης των κινητικών μονάδων
description: The rate of torque development is a useful tool to evaluate explosive force. There are multiple factors that affect the rate of torque development. One of them is force, which may significantly increase after training. The present study evaluates the adaptations of rate of torque development at neuromuscular level after long-term soccer training in pre-pubertal boys. Fifteen healthy, elite football players (age: 10.03±0.56 years) and fifteen age-matched, healthy, prepubertal boys (age: 9.73±0.38 years), were measured during maximal voluntary isometric knee extension in peak torque, rate of torque development, and electromyographic activity (amplitude and frequency component) during the first 30 ms, 50 ms, 100 ms and 200 ms after the torque onset. The results showed that trained boys had significantly greater values in peak isometric torque, in peak rate of torque development and in rate of torque development at 0-50 ms, 0-100 ms, and 0–200ms, and increase electromyographic frequency for the vastus lateralis. These results indicate that long-term soccer training in children has positive effect in the rate of torque development which could be attributed to the increased motor unit firing rate

description: Detection of higher order modes of gravitational waves in third-generation (3G) ground-based detectors such as Cosmic Explorer and Einstein Telescope is explored. Using the astrophysical population of binary black holes based on events reported in the second gravitational wave catalog by Laser Interferometer Gravitational Wave Observatory (LIGO) and Virgo (GWTC-2), in conjunction with the Madau-Dickinson model for redshift evolution of the binary black hole mergers, we assess the detectability of these higher order modes using a network consisting of three third-generation detectors. We find that the two subleading modes [(3,3) and (4,4)] can be detected in approximately 30% of the population with a network signal-to-noise ratio of 3 or more, and for nearly 10% of the sources, the five leading modes will be detectable. Besides, a study concerning the effect of binary's mass ratio and its orbital inclination with the observer's line-of-sight in detecting various modes is presented. For a few selected events of the LIGO-Virgo catalog, we identify the modes that would have been detected if a third-generation detector was operational when these events were recorded. We also compute the detectability of higher modes by Voyager and find that only $\sim$ 6 and 2% of the detectable population will have an associated detection of (3,3) and (4,4) modes, respectively. Observing these higher order modes in the 3G era would have a huge impact on the science possible with these detectors ranging from astrophysics and cosmology to testing strong-field gravity.

description: The Run I results on the searches for new physics in photon final states were intriguing. The rare 2 electrons + 2 photons + missing transverse energy (MET) candidate event and the measured event rate for the signature lepton + photon + MET, which was 2.7 sigma above the Standard Model predictions, sparked signature-based searches in the photon + photon + X and lepton + photon + X channels. With more data in Run II we should be able to answer a simple question: was it an anomaly or were the Run I results the first evidence for the new physics? We present searches for New Physics in Photon Final States at CDF Run II, Fermilab, with substantially more data and a higher $\pbarp$ collision energy, 1.96 TeV, and the upgraded CDF detector (CDF II).

International joint ventures: the strategic human resource management dimension
Creators: name: Cyr, Dianne J.
Publisher: name: University of British Columbia

description: International joint ventures are frequently a response to external pressures placed on globally-oriented companies if they are to survive and compete successfully. Within the international context, a critical element to corporate competitiveness is the effective management of human resources. Despite this reality, very little research to date examines the strategic Human Resource Management (HRM) dimension in international joint ventures. In this investigation, strategic HRM refers to communication systems, staffing, reward and recognition, training, and performance appraisal systems which operate within four successful joint venture (JV) firms. All joint ventures have been formed between two international partners, each from a different national culture. Three of the companies are 50/50 ownership arrangements, while the fourth venture has a 60/40 ownership split between the partners. All four ventures are in the manufacturing sector, although indifferent market niches. In each case, managers in the joint ventures focus on total quality management and high employee involvement in order to enhance product quality and innovation, and to create a more satisfying environment in which employees can contribute to the organization. Collectively, these joint ventures provide an interesting window through which to view strategic HRM operations. In addition to the description of Human Resource policy and practice, the research pursues an understanding of the more evasive questions as to how and why HRM operates as it does. Issues which evolved from the research and are important to a fuller comprehension of HRM in international joint ventures include, among others: the management of the JV-parent relationship; how HRM policy and practice supports or limits parent and JV strategic objectives; the select influence which national culture has on HRM; how corporate culture develops in the JV related to parent influences and JV managerial contributions; and finally, how organizational learning operates at both strategic and tactical levels in each venture.

description: In this paper we study the phonon's effect on the position of the 1s excitonic resonance of the fundamental absorption transition line in two-dimensional transition metal dichalcogenides. We apply our theory to WS$_{2}$a two-dimensional material where the shift in absorption peak position has been measured as a function of temperature. The theory is composed of two ingredients only: i) the effect of longitudinal optical phonons on the absorption peak position, which we describe with second order perturbation theory; ii) the effect of phonons on the value of the single particle energy gap, which we describe with the Huang Rhys model. Our results show an excellent agreement with the experimentally measured shift of the absorption peak with the temperature.

description: Properties of intermediate mass nuclei have been investigated within the framework of the alpha-cluster model in combination with systematic double-folding potentials. Previously, this alpha-cluster model has been widely applied to light nuclei, in particular to 8Be = alpha \otimes alpha, 20Ne = 16O \otimes alpha, and 44Ti = 40Ca \otimes alpha, and to heavy nuclei, in particular to 212Po = 208Pb \otimes alpha. In the present work a wide range of nuclei is investigated with the magic neutron number N = 50 in the mass range around A \approx 80 - 100: (A+4,N=52) = (A,N=50) \otimes alpha. It is found that excitation energies, decay properties, and transition strengths can be described successfully within this model. The smooth and small variation of the underlying parameters of the alpha-nucleus potential may be used for extrapolations to predict experimentally unknown properties in the nuclei under study.

description: We train convolutional neural networks to predict whether or not a set of measurements is informationally complete to uniquely reconstruct any given quantum state with no prior information. In addition, we perform fidelity benchmarking based on this measurement set without explicitly carrying out state tomography. The networks are trained to recognize the fidelity and a reliable measure for informational completeness. By gradually accumulating measurements and data, these trained convolutional networks can efficiently establish a compressive quantum-state characterization scheme by accelerating runtime computation and greatly reducing systematic drifts in experiments. We confirm the potential of this machine-learning approach by presenting experimental results for both spatial-mode and multiphoton systems of large dimensions. These predictions are further shown to improve when the networks are trained with additional bootstrapped training sets from real experimental data. Using a realistic beam-profile displacement error model for Hermite-Gaussian sources, we further demonstrate numerically that the orders-of-magnitude reduction in certification time with trained networks greatly increases the computation yield of a large-scale quantum processor using these sources, before state fidelity deteriorates significantly.

description: We find that the Rashba spin splitting is intrinsically a nonlinear function of the momentum, and the linear Rasha model may overestimate it significantly, especially in narrow-gap materials. A nonlinear Rashba model is proposed, which is in good agreement with the numerical results from the eight-band kp theory. Using this model, we find pronounced suppression of the D'yakonov-Perel' spin relaxation rate at large electron densities, and a non-monotonic dependence of the resonance peak position of electron spin lifetime on the electron density in [111]-oriented quantum wells, both in qualitative disagreement with the predictions of the linear Rashba model.

description: Από τις αρχές τις δεκαετίας του ’90 μέχρι και σήμερα, η Ελλάδα, κυρίως λόγω της γεωγραφικής της θέσης, βρίσκεται αντιμέτωπη με μαζικές εισροές μεταναστευτικών ρευμάτων. Παρά το γεγονός ότι οι μετανάστες αποτελούν ουσιαστικά αναπόσπαστο κομμάτι της σύγχρονης ελληνικής κοινωνίας, με περισσότερα από είκοσι χρόνια συνύπαρξης με τον ημεδαπό πληθυσμό, φαινόμενα όπως ο ρατσισμός, η ξενοφοβία και η εκμετάλλευση των αλλοδαπών, συνθέτουν μέχρι και σήμερα την ελληνική πραγματικότητα, ιδιαιτέρως μετά την προσφυγική κρίση του 2015, οπότε και μέρος της, αποδυναμωμένης από τη σφοδρή οικονομική κρίση των τελευταίων ετών, ελληνικής κοινωνίας, καταφέρθηκε ακόμα χειρότερα εναντίον τους. Ιδιαίτερα τα τελευταία χρόνια, πληθαίνουν οι φωνές που διατείνονται υπέρ τις άποψης ότι οι μετανάστες αποτελούν απειλή για την ασφάλεια και την ευημερία του τόπου και ότι πρέπει να απομακρυνθούν από τη χώρα με κάθε κόστος, ακόμα και, σε κάποιες περιπτώσεις, με τίμημα τη ζωή τους. Κατόπιν των ανωτέρω, τίθενται στο επίκεντρο της παρούσας ανάλυσης οι μετανάστες και οι πρόσφυγες, τόσο ως θύματα, όσο και ως θύτες του εγκλήματος, σε μια προσπάθεια να αναλυθεί με σαφήνεια η θέση τους στον κοινωνικό ιστό, σε μια εποχή που χαρακτηρίζεται από την ετερογένεια και την πολυπολιτισμικότητα, λαμβάνοντας υπόψη όλες τις συνέπειες που μπορεί να επιφέρει αυτός ο χαρακτηρισμός
description: Ever since the beginning of the ‘90s decade, to this day, Greece, mainly because of its strategic location, has received mass influxes of immigrants and refugees. Despite the fact that immigrants have become an integral part of the Greek society, coexisting with the native population for more than twenty years, phenomena such as racism, xenophobia and exploitation of the foreigners, are still making an appearance in the Greek reality, especially after the refugee crisis of 2015, when a large portion of the, extremely weakened because of the severe financial crisis Greece faces since 2009, Greek society, has turned against them. Especially during the last few years, there are more and more people who believe that immigrants pose a threat for the safety and prosperity of the country, and that they should be immediately removed from the country at all costs, even at the cost of their lives. In light of the foregoing, this masters’ thesis focuses on the analysis of immigrants and refugees, both as victims and as criminals, attempting to shed light on their place in the social fabric, during a time that is characterized by heterogeneity and multiculturalism, taking into consideration all the consequences that characterization might have

description: Recently, a birational representation of an extended affine Weyl group of type $A_{mn-1}^{(1)}\times A_{m-1}^{(1)}\times A_{m-1}^{(1)}$ was proposed with the aid of a cluster mutation. In this article we formulate this representation in a framework of a system of $q$-difference equations with $mn\times mn$ matrices. This formulation is called a Lax form and is used to derive a generalization of the $q$-Garnier system.

Thermally Stable Nuclear Burning on Accreting White Dwarfs

description: One of the challenges to increasing the mass of a white dwarf through accretion is the tendency for the accumulating hydrogen to ignite unstably and potentially trigger mass loss. It has been known for many years that there is a narrow range of accretion rates for which the hydrogen can burn stably, allowing for the white dwarf mass to increase as a pure helium layer accumulates. We first review the physics of stable burning, providing a clear explanation for why radiation pressure stabilization leads to a narrow range of accretion rates for stable burning near the Eddington limit, confirming the recent work of Nomoto and collaborators. We also explore the possibility of stabilization due to a high luminosity from beneath the burning layer. We then examine the impact of the beta-decay-limited ''hot'' CNO cycle on the stability of burning. Though this plays a significant role for accreting neutron stars, we find that for accreting white dwarfs, it can only increase the range of stably-burning accretion rates for metallicities below 0.01 solar metallicity.

description: Recently, we have shown that for conditions under which the so-called light-shift imbalance induced blockade (LSIIB) occurs, the collective excitation of an ensemble of a multi-level atom can be treated as a closed two level system. In this paper, we describe how such a system can be used as a quantum bit (qubit) for quantum communication and quantum computing. Specifically, we show how to realize a C-NOT gate using the collective qubit and an easily accessible ring cavity, via an extension of the so-called Pellizzari scheme. We also describe how multiple, small-scale quantum computers realized using these qubits can be linked effectively for implementing a quantum internet. We describe the details of the energy levels and transitions in 87Rb atom that could be used for implementing these schemes.

description: We derive the rest-frame $K$-band luminosity function for galaxies in 32 clusters at $0.6 < z < 1.3$ using deep $3.6μ$m and $4.5μ$m imaging from the Spitzer Space Telescope InfraRed Array Camera (IRAC). The luminosity functions approximate the stellar mass function of the cluster galaxies. Their dependence on redshift indicates that massive cluster galaxies (to the characteristic luminosity $M^*_K$) are fully assembled at least at $z \sim 1.3$ and that little significant accretion takes place at later times. The existence of massive, highly evolved galaxies at these epochs is likely to represent a significant challenge to theories of hierarchical structure formation where such objects are formed by the late accretion of spheroidal systems at $z < 1$.

description: We investigate the classical counterpart of an effective Hamiltonian for a strongly trimerized kagome lattice. Although the Hamiltonian only has a discrete symmetry, the classical groundstate manifold has a continuous global rotational symmetry. Two cases should be distinguished for the sign of the exchange constant. In one case, the groundstate has a 120^\circ spin structure. To determine the transition temperature, we perform Monte-Carlo simulations and measure specific heat, the order parameter as well as the associated Binder cumulant. In the other case, the classical groundstates are macroscopically degenerate. A thermal order-by-disorder mechanism is predicted to select another 120^\circ spin-structure. A finite but very small transition temperature is detected by Monte-Carlo simulations using the exchange method.
