description: In the case of the need of extraordinary security, Kirchhoff-loop-Johnson-(like)-noise ciphers can easily be integrated on existing types of digital chips in order to provide secure data communication between hardware processors, memory chips, hard disks and other units within a computer or other data processor system. The secure key exchange can take place at the very first run and the system can renew the key later at random times with an authenticated fashion to prohibit man-in-the-middle attack. The key can be stored in flash memories within the communicating chip units at hidden random addresses among other random bits that are continuously generated by the secure line but are never actually used. Thus, even if the system is disassembled, and the eavesdropper can have direct access to the communication lines between the units, or even if she is trying to use a man-in-the-middle attack, no information can be extracted. The only way to break the code is to learn the chip structure, to understand the machine code program and to read out the information during running by accessing the proper internal ports of the working chips. However such an attack needs extraordinary resources and even that can be prohibited by a password lockout. The unconditional security of commercial algorithms against piracy can be provided in a similar way.

description: We present a simplified solution to orbit determination of a binary system from astrometric observations. An exact solution was found by Asada, Akasaka and Kasai by assuming no observational errors. We extend the solution considering observational data. The generalized solution is expressed in terms of elementary functions, and therefore requires neither iterative nor numerical methods.

description: Dil, sadece milletlerin birbiriyle anlaşmasını sağlayan bir araç değil, aynı zamanda duyguların, düşüncelerin ve fikirlerin aktarılmasında kilit bir role sahiptir. Bu özelliği sayesinde toplumlar arasında iletişim birlikteliği oluşmuş ve insanlar, diğer toplumlardaki bağlarını güçlendirmişlerdir. Duygu ve düşüncelerin ifadesinde dilin yanı sıra iletişim organları da kullanılarak bağlantı kurulmuş; bu süreçte gazeteler, insanların duygu ve düşüncelerini aktarmak için önemli bir araç haline gelmiştir.Gazetecilik dilinde geçmişten bugüne kadar pek çok konu ve duygu yer almış, bu konular dönemlerle, yöneticilerle, kişilerle ve toplumla bağlantılık göstermiştir. Gazetelerin toplum olaylarına paralel gitmesi, halkın gazeteyi benimsemesi ve okuması için yönlendirici, düşündürücü ve yol gösterici bir konumda olmalarını gerektirmektedir. Bu bağlamda, Tasvîr-i Efkâr gazetesi özellikle 2. Meşrutiyet döneminde, Ebuzziya Tevfik’in yönetimiyle toplumu etkilemeyi başarmış ve statüsünü korumuştur. Gazetelerin, toplumun ihtiyaçlarına yönelik olarak yazılar kaleme alması önemlidir. Örneğin, 1940-1942 yılları arasında Tasvîr-i Efkâr gazetesinde 2. Dünya Savaşı’nın etkilerine odaklanan yazılar, toplumu yönlendirici ve düşündürücü bir rol üstlenmiştir. Bu dönemde “Vecizeler” başlığı altında sunulan özlü sözler, sadece hikmetli ifadeler değil, aynı zamanda dönemin ihtiyaçlarına uygun olarak toplumu yönlendirici bir işlev görmüştür. Bu köşede toplumsal-sosyal, siyasi-askeri, bireysel, dil ve din konularına odaklanılması, gazetenin çeşitli perspektifleri ele almasını sağlamıştır.

description: The magnetar model and a solid quark star model for anomalous X-ray pulsars/soft gamma-ray repeaters (AXPs/SGRs) are discussed. Different manifestations of pulsar-like stars are speculated to be due to both their nature (e.g., mass and strain) and their nurture (ambience, and consequently the type of accretion) in the solid quark star scenario. Relevant arguments made by the author's group, including a debate on solid cold quark matter, are briefly summarized too.

description: Rare-earth nickelates R$^{3+}$Ni$^{3+}$O$_3$ (R=Lu-Pr, Y) show a striking metal-insulator transition in their bulk phase whose temperature can be tuned by the rare-earth radius. These compounds are also the parent phases of the newly identified infinite layer RNiO2 superconductors. Although intensive theoretical works have been devoted to understand the origin of the metal-insulator transition in the bulk, there have only been a few studies on the role of hole and electron doping by rare-earth substitutions in RNiO$_3$ materials. Using first-principles calculations based on density functional theory (DFT) we study the effect of hole and electron doping in a prototypical nickelate SmNiO3. We perform calculations without Hubbard-like U potential on Ni 3d levels but with a meta-GGA better amending self-interaction errors. We find that at low doping, polarons form with intermediate localized states in the band gap resulting in a semiconducting behavior. At larger doping, the intermediate states spread more and more in the band gap until they merge either with the valence (hole doping) or the conduction (electron doping) band, ultimately resulting in a metallic state at 25% of R cation substitution. These results are reminiscent of experimental data available in the literature and demonstrate that DFT simulations without any empirical parameter are qualified for studying doping effects in correlated oxides and to explore the mechanisms underlying the superconducting phase of rare-earth nickelates.

description: We consider the job-shop problem with sequence-dependent setup times. We focus on the formal definition of schedule generation schemes (SGSs) based on the semi-active, active, and non-delay schedule categories. We study dominance properties of the sets of schedules obtainable with each SGS. We show how the proposed SGSs can be used within single-pass and multi-pass priority rule based heuristics. We study several priority rules for the problem and provide a comparative computational analysis of the different SGSs on sets of instances taken from the literature. The proposed SGSs significantly improve previously best-known results on a set of hard benchmark instances.
Two rest stops along the Trans Canada Trail

Publisher: name: University of British Columbia
Year: 2009

description: Within the next decade an inter provincial trail, called the Trans Canada Trail, will be developed to accommodate non-motorized traffic such as hikers, skiers, horsemen, and cyclists. Anticipating the need for rest stop facilities, this thesis seeks to explore the design potential of two isolated facilities. The focus of this exploration is the impact of landscape on the development of architectural form. While existing conditions found in each site were recorded and considered throughout the design process, a conscious effort was also made to build a site rather than site plan This position, first articulated by William Rees Morrish in his book Civilizing Terrain. acknowledges that not every piece of land can become an urban place. Instead, placemaking often requires willful acts of change in order to enhance or more effectively reveal its existing qualities. This position opposes the current attitude fostered by the environmental movement that all landscapes should remain untouched. The two sites selected were both located in western Canada: one on the eastern shore of Lake in southern British Columbia and the other in a farmer's field near Milk River in southern Alberta. This thesis traces the discoveries and attempts made to locate a center, develop an arrival sequence and insert an architectural form into the experience of the landscape. Both sites were explored simultaneously, reaching a similar level of resolution, at which point the British Columbia site was dropped and the prairie site was developed further. The Alberta site then became the developed body of the thesis.

description: Gradient flow in a potential energy (or Euclidean action) landscape provides a natural set of paths connecting different saddle points. We apply this method to General Relativity, where gradient flow is Ricci flow, and focus on the example of 4-dimensional Euclidean gravity with boundary S^1 x S^2, representing the canonical ensemble for gravity in a box. At high temperature the action has three saddle points: hot flat space and a large and small black hole. Adding a time direction, these also give static 5-dimensional Kaluza-Klein solutions, whose potential energy equals the 4-dimensional action. The small black hole has a Gross-Perry-Yaffe-type negative mode, and is therefore unstable under Ricci flow. We numerically simulate the two flows seeded by this mode, finding that they lead to the large black hole and to hot flat space respectively, in the latter case via a topology-changing singularity. In the context of string theory these flows are world-sheet renormalization group trajectories. We also use them to construct a novel free energy diagram for the canonical ensemble.

The Destruction of 3He by Rayleigh-Taylor Instability on the First Giant Branch

description: Low-mass stars, ~1-2 solar masses, near the Main Sequence are efficient at producing 3He, which they mix into the convective envelope on the giant branch and distribute into the Galaxy by way of envelope loss. This process is so efficient that it is difficult to reconcile the observed cosmic abundance of 3He with the predictions of Big Bang nucleosynthesis. In this paper we find, by modeling a red giant with a fully three-dimensional hydrodynamic code and a full nucleosynthetic network, that mixing arises in the supposedly stable and radiative zone between the hydrogen-burning shell and the base of the convective envelope. This mixing is due to Rayleigh-Taylor instability within a zone just above the hydrogen-burning shell. In this zone the burning of the 3He left behind by the retreating convective envelope is predominantly by the reaction 3He + 3He -> 4He + 2p, a reaction which, untypically for stellar nuclear reactions, {\it lowers} the mean molecular weight, leading to a local minimum. This local minimum leads to Rayleigh-Taylor instability, and turbulent motion is generated which will continue ultimately up into the normal convective envelope. Consequently material from the envelope is dragged down sufficiently close to the burning shell that the 3He in it is progressively destroyed. Thus we are able to remove the threat that 3He production in low-mass stars poses to the Big Bang nucleosynthesis of 3He. Some slow mixing mechanism has long been suspected, that connects the convective envelope of a red giant to the burning shell. It appears to be necessary to account for progressive changes in the 12C/13C and 14N/12C ratios on the First Giant Branch. We suggest that these phenomena are also due to the Rayleigh-Taylor-unstable character of the 3He-burning region.

description: We present a spectroscopic survey of Ly$α$ emitters (LAEs) at $z\approx3.1$ in the Subaru MM-Newton Deep Survey Field. This field has deep imaging data in a series of broad and narrow bands, including two adjacent narrow bands NB497 and NB503 that have allowed us to efficiently select LAE candidates at $z\approx3.1$. Using spectroscopic observations on MMT Hectospec and Magellan M2FS, we obtained a sample of 166 LAEs at $z\approx3.1$ over an effective area of $\sim$1.2 deg$^2$, including 16 previously known LAEs. This is so far the largest (spectroscopically confirmed) sample of LAEs at this redshift. We make use of the secure redshifts and multi-band data to measure spectral properties such as Ly$α$ luminosity and rest-frame UV slope. We derive a robust Ly$α$ luminosity function (LF) that spans a luminosity range from $\sim10^{42.0}$ to $>10^{43.5}$ erg s$^{-1}$. Significant overdense and underdense regions are detected in our sample, but the area coverage is wide enough to largely suppress the effect from such cosmic variance. Our Ly$α$ LF is generally consistent with those from previous studies at $z \sim 3.1$. At the brightest end of the LF, there is a tentative detection of a density excess that is not well described by the Schechter function. The comparison with the LFs at other redshifts suggests that the Ly$α$ LF does not show significant evolution at $2

description: Embedding silicon nanoparticles in an intermetallic matrix is a promising strategy to produce remarkable bulk anode materials for lithium-ion (Li-ion) batteries with low potential, high electrochemical capacity and good cycling stability. These composite materials can be synthetized at a large scale using mechanical milling. However, for Si-Ni3Sn4 composites, milling also induces a chemical reaction between the two components leading to the formation of free Sn and NiSi2, which is detrimental to the performance of the electrode. To prevent this reaction, a modification of the surface chemistry of the silicon has been undertaken. Si nanoparticles coated with a surface layer of either carbon or oxide were used instead of pure silicon. The influence of the coating on the composition, (micro)structure and electrochemical properties of Si-Ni3Sn4 composites is studied and compared with that of pure Si. Si coating strongly reduces the reaction between Si and Ni3Sn4 during milling. Moreover, contrary to pure silicon, Si-coated composites have a plate-like mor-phology in which the surface-modified silicon particles are surrounded by a nanostructured, Ni3Sn4-based matrix leading to smooth potential profiles during electrochemical cycling. The chemical homogeneity of the matrix is more uniform for carbon-coated than for oxygen-coated silicon. As a consequence, different electrochemical behaviors are obtained depending on the surface chemistry, with better lithiation properties for the carbon-covered silicon able to deliver over 500 mAh/g for at least 400 cycles.

description: The Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars (SISTINE) is a rocket-borne ultraviolet (UV) imaging spectrograph designed to probe the radiation environment of nearby stars. SISTINE operates over a bandpass of 98 -- 127 and 130 -- 158 nm, capturing a broad suite of emission lines tracing the full 10$^4$ -- 10$^5$ K formation temperature range critical for reconstructing the full UV radiation field incident on planets orbiting solar-type stars. SISTINE serves as a platform for key technology developments for future ultraviolet observatories. SISTINE operates at moderate resolving power ($R\sim$1500) while providing spectral imaging over an angular extent of $\sim$6', with $\sim$2" resolution at the slit center. The instrument is composed of an f/14 Cassegrain telescope that feeds a 2.1x magnifying spectrograph, utilizing a blazed holographically ruled diffraction grating and a powered fold mirror. Spectra are captured on a large format microchannel plate (MCP) detector consisting of two 113 x 42 mm segments each read out by a cross delay-line anode. Several novel technologies are employed in SISTINE to advance their technical maturity in support of future NASA UV/optical astronomy missions. These include enhanced aluminum lithium fluoride coatings (eLiF), atomic layer deposition (ALD) protective optical coatings, and ALD processed large format MCPs. SISTINE was launched a total of three times with two of the three launches successfully observing targets Procyon A and $α$ Centauri A and B.

description: We present measurement and analysis techniques that allow the complete complex magneto-conductivity tensor to be determined from mid-infrared (11-1.6 micron; 100-800 meV) measurements of the complex Faraday (theta_F) and Kerr (theta_K) angles. Since this approach involves measurement of the geometry (orientation axis and ellipticity of the polarization) of transmitted and reflected light, no absolute transmittance or reflectance measurements are required. Thick film transmission and reflection equations are used to convert the complex theta_F and theta_K into the complex longitudinal conductivity sigma_xx and the complex transverse (Hall) conductivity sigma_xy. theta_F and theta_K are measured in a Ga_(1-x)Mn_xAs and SrRuO_3 films. The resulting sigma_xx is compared to the values obtained from conventional transmittance and reflectance measurements, as well as the results from Kramers-Kronig analysis of reflectance measurements on similar films.

Using indigenous knowledge in resource management: knowledge of salmon in the upper St’át’imc (Lillooet, B.C.)
Creators: name: DeShield, Coral Ginger
Publisher: name: University of British Columbia
Year: 2009

description: Recognition and use of indigenous knowledge in resource management can increase the information available about the resource and facilitate establishment of a larger management role for local resource users. This paper examines the use of indigenous knowledge in resource management using the case of knowledge of Pacific salmon {Oncorhynchus spp.) among the Upper St'at'imc, near Lillooet, British Columbia (B.C.). Salmon in the study area are currently managed by the federal Department of Fisheries and Oceans (DFO). This system was established in the 1940s and overlays a traditional management system consisting of fishing site ownership, a well-defined system of access to sites, rules of conduct at fishing sites for the catching and processing of fish, and harvest restrictions. Recent DFO policy changes, signified by the Aboriginal Fisheries Strategy, indicate a movement toward a larger management role for First Nations. This study addresses what indigenous knowledge is available, how it compares to knowledge used by the Department of Fisheries and Oceans, and how indigenous knowledge can be used in modern salmon stock management. A literature review was supplemented by interviews with elders, young Upper St'at'imc leaders, and both DFO and non-DFO biologists. Current indigenous knowledge pertains to salmon stocks, habitat, and practices and philosophy. Indigenous knowledge can be primarily distinguished from western scientific knowledge on the basis of the following properties of the indigenous system: a greater amount of qualitative vs. quantitative information; an obvious recognition and discussion of anomalies; the perception of a wide range of variables in a region; the use of specific local technology; the development of analysis based on both observations over a medium-sized area and traditional ideologies; and differences in institutional arrangements for gathering knowledge. Differences between indigenous and western scientific knowledge are related to the requirement that DFO accumulate and process a large amount of information over a very large geographical area. Several barriers exist to using indigenous knowledge in modern resource management, including the fact that indigenous knowledge does not fit readily into established methods for gathering and analyzing data. Using indigenous knowledge may be facilitated by innovations at both the local and state levels.

The concept of this state, that the person knows that he is identified with god is being called liberation. But the liberation is not only a state of concentration, or contemplation on god. This is duality. The concept of the liberation is equal with the concept of meditation. The majesty is the key that shows the ontological process how to be aware of the true nature, how to experiencing the ultimate adobe of the Lord.

description: Maturity models for software indicate the key areas that contribute to quality improvements. They usually combine technical, organisational and human aspects relevant for effective software development, to focus the efforts and draw the direction for optimisations. In this paper, we present the process of defining best practices that support the GÉANT Software Maturity Model (GSMM), aligned to the needs of a distributed, innovation-driven, pan-European organisation. Based on the identification of specific goals relevant for GÉANT and a preliminary maturity assessment, we created a catalogue of best practices that help the software teams to attain the goals defined in the GSMM.

description: The large separation in the low radial order regime is considered as a highly valuable observable to derive mean densities of $δ$ Scuti stars, due to its independence with rotation. Up to now, theoretical studies of this $Δν$-${\bar ρ}$ relation have been limited to 1D non-rotating models, and 2D pseudo-evolutionary models. The present work aims at completing this scenario by investigating quantitatively the impact of rotation in this relation on a large grid of 1D asteroseismic models representative of $δ$ Scuti stars. These include rotation effects on both the stellar evolution and the interaction with pulsation. This allowed us to compute the stellar deformation, get the polar and equatorial radii, and correct the stellar mean densities. We found that the new $Δν$-${\bar ρ}$ relation for rotating models is compatible with previous works. We explained the dispersion of the points around the linear fits as caused mainly by the distribution of the stellar mass, and partially by the evolutionary stage. The new fit is found to be close to the previous theoretical studies for lower masses ($1.3-1.81\,\mathrm{M}_{\odot}$). However, the opposite holds for the observations: for the higher masses ($1.81-3\,\mathrm{M}_{\odot}$) the fit is more compatible with the empirical relation. We applied these results to characterise the two well-known $δ$ Scuti stars observed by CoRoT, HD174936 and HD174966, and compared the physical parameters with those of previous works. Inclusion of rotation in the modelling causes a tendency towards greater masses, radii, luminosities and lower density values. Comparison between $Δν$ and Gaia's luminosities also allowed us to constraint the inclination angles and rotational velocities of both stars. The present results pave the way to systematically constrain the angle of inclination of $δ$ Scuti stars

description: We propose Greedy Topology-Aware Quantum Circuit Partitioning (GTQCP), a novel quantum gate circuit partitioning method which partitions circuits by applying a greedy heuristic to the qubit dependency graph of the circuit. GTQCP is compared against three other gate partitioning methods, two of which (QuickPartitioner and ScanPartitioner) are part of the Berkley Quantum Synthesis Toolkit. GTQCP is shown to have 18% run time improvement ratio over the fastest approach (QuickPartitioner), and a 96% improvement over the highest quality approach (ScanPartitioner). The algorithm also demonstrates nearly identical result quality (number of partitions) compared with ScanPartitioner, and a 38% quality improvement over QuickPartitioner.

description: We study the degree to which the coherence of quantum states is affected by noise. We give the definition of the $n$-th decay rate and investigate the coherence of Bell-diagonal states under $n$ iterations of channels. We derive explicit formulas of the $n$-th decay rates based on $l_1$ norm of coherence, relative entropy of coherence and skew information-based coherence. It is found that the larger $n$ is, the faster the $n$-th decay rate decreases as the parameter $p$ of Bell-diagonal states increases. Moreover, for any fixed $n$, with the increase of $p$, Bell-diagonal states can be completely incoherent under generalized amplitude damping (GAD) channels, depolarization (DEP) channels and phase flip (PF) channels, while this is not the case for bit flip (BF) channels and bit-phase flip (BPF) channels. We also investigate the geometry of the relative entropy of coherence and skew information-based coherence of Bell-diagonal states under different channels when the $n$-th decay rate is one, i.e., the coherence is frozen. It is shown that compared with BF and BPF channels, when $n$ is large enough, the coherence of Bell-diagonal states will not be frozen under GAD, DEP and PF channels. For skew information-based coherence, similar properties of coherence freezing are found.

description: We present a method to model the interaction and the dynamics of atoms excited to Rydberg states. We show a way to solve the optical Bloch equations for laser excitation of the frozen gas in good agreement with the experiment. A second method, the Kinetic Monte Carlo method gives an exact solution of rate equations. Using a simple N-body integrator (Verlet), we are able to describe dynamical processes in space and time. Unlike more sophisticated methods, the Kinetic Monte Carlo simulation offers the possibility of numerically following the evolution of tens of thousands of atoms within a reasonable computation time. The Kinetic Monte Carlo simulation gives good agreement with dipole-blockade type of experiment. The role of ions and the individual particle effects are investigated.

Publisher: name: Zenodo
Year: 2024

description: Abstract. This study addresses portfolio optimization through a comparative analysis

of models. Utilizing 15 stocks from S&P 500 over 12 years, it contrasts optimal weights

and objective values of five models: Konno and Yamazaki (KY), Feinstein and Thapa

(FT), Adjusted Feinstein and Thapa (AFT), and Adjusted ChiangLin et al. (ALC).

Employing Pyomo in Python with GLPK solver, findings reveal KY and LC models have

identical outcomes. AFT model approximates KY and LC solutions. Modified AFT and

ALC models, with short selling and risk-neutral interest rates, closely mimic KY’s results.

The study recommends KY’s model or a modified ALC model for portfolio optimization.
Rainbow universe

description: The formalism of rainbow gravity is studied in a cosmological setting. We consider the very early universe which is radiation dominated. A novel treatment in our paper is to look for an ``averaged'' cosmological metric probed by radiation particles themselves. Taking their cosmological evolution into account, we derive the modified Friedmann-Robertson-Walker(FRW) equations which is a generalization of the solution presented by Magueijo and Smolin. Based on this phenomenological cosmological model we argue that the spacetime curvature has an upper bound such that the cosmological singularity is absent. These modified $FRW$ equations can be treated as effective equations in the semi-classical framework of quantum gravity and its analogy with the one recently proposed in loop quantum cosmology is also discussed.

description: Σκοπός της παρούσας εργασίας είναι να εξετάσει τη δυνατότητα αξιοποίησης του Εκπαιδευτικού Δράματος στην Παιδαγωγική της Ειρήνης. Αρχικά παρουσιάζεται το θεωρητικό υπόβαθρο τόσο της Παιδαγωγικής της Ειρήνης, όσο και του Εκπαιδευτικού Δράματος και των κοινωνικών μορφών θεάτρου στην εκπαίδευση. Στη συνέχεια, η εργασία προσπαθεί να ανιχνεύσει και να καταγράψει τα σημεία τομής ανάμεσα στα δύο πεδία σε θεωρητικό επίπεδο, αλλά και σε επίπεδο πρακτικής εφαρμογής, τόσο στην τυπική όσο και στην μη τυπική εκπαίδευση. Εξετάζεται το κοινό πλαίσιο, αναδεικνύεται η συγκλίνουσα οπτική και διερευνάται η δυναμική της αμφίδρομης σχέσης των δύο πεδίων. Βασική διαπίστωση που προκύπτει είναι ότι το Εκπαιδευτικό Δράμα, ως μεθοδολογικό εργαλείο του ευρύτερου εφαρμοσμένου και κοινωνικού θεάτρου, μπορεί να συμβάλει αποτελεσματικά στην πραγμάτωση των στόχων της Παιδαγωγικής της Ειρήνης, η οποία οραματίζεται μια εκπαίδευση αξιών που στοχεύει στη θετική ειρήνη, την κοινωνική δικαιοσύνη και τον σεβασμό των ανθρωπίνων δικαιωμάτων. Η έρευνα εστιάζει ιδιαίτερα στην σχέση του Εκπαιδευτικού Δράματος με την Κριτική Παιδαγωγική της Ειρήνης, μιας εκπαίδευσης αιτιώδους γνώσης αρχικά, συνειδητοποίησης αργότερα και, εντέλει, προσωπικού και κοινωνικού μετασχηματισμού.
description: The aim of this thesis is to explore the possibility of incorporating Educational Drama in Peace Education. The thesis firstly presents the theoretical background of the Pedagogy of Peace, Educational Drama and social kinds of theatre in education. It then attempts to detect and highlight the common ground covered by the two fields in theory and practice, in both formal and non formal educational activities. Furthermore, the thesis presents the common framework of the two fields, indicates their converging points of view and examines their dynamic relation. A fundamental result emerging from the author’s research is that Educational Drama, as a methodological tool of applied and social theatre, can effectively contribute towards realizing the objectives of Peace Education, which aims at positive peace, social justice and respect for human rights. The author’s research focuses in particular on how Educational Drama relates to the Critical Pedagogy of Peace, which can activate causal knowledge, critical awareness and, therefore, transformation of life.

description: We investigate the dependence of physical properties of galaxies brighter than M_r=-18.0 in the SDSS on environment, as measured by local density using an adaptive smoothing kernel. We find that variations of galaxy properties with environment are almost entirely due to the dependence of morphology and luminosity on environment. Because galaxy properties depend not only on luminosity but also on morphology, it is clear that galaxy properties cannot be determined solely by dark halo mass. When morphology and luminosity are fixed, other physical properties, such as color, color-gradient, concentration, size, velocity dispersion, and star formation rate, are nearly independent of local density. The only feature is the sharp decrease of late type fraction above the critical luminosity of about M_r=-21.3 in the morphology versus luminosity relation. Weak residual dependences on environment include that of the color of late-types (bluer at lower density) and of the L-sigma relation of early-types (larger dispersion at higher density for bright galaxies). The early-type fraction is a monotonically increasing function of local density and luminosity. The morphology-density- luminosity relation should be a key constraint on galaxy formation models. We demonstrate that the dependence on environment of the morphology of galaxie originates from variations in density on effective Gaussian smoothing scales much smaller than 12 h^{-1}Mpc. We find that galaxy morphology varies both with density measured on an effective Gaussian smoothing scale of 4.7 h^{-1} Mpc and on distance to the nearest bright galaxy (particularly, for about 0.2 h^{-1}Mpc). We propose a mechanism that the morphology of galaxies in galaxy systems is transformed by the tidal force.

description: Considerable effort has been devoted to the automatic extraction of information about action of the face from image sequences. Within the context of human-computer interaction (HCI) we may distinguish systems that allow expression from those which aim at recognition. Most of the work in facial action processing has been directed at automatically recognizing affect from facial actions. By contrast, facial gesture interfaces, which respond to deliberate facial actions, have received comparatively little attention. This paper reviews several projects on vision-based interfaces that rely on facial action for intentional HCI. Applications to several domains are introduced, including text entry, artistic and musical expression and assistive technology for motor-impaired users.

description: Let M be a compact manifold with a fixed spin structure χ. The Atiyah-Singer index theorem implies that for any metric g on M the dimension of the kernel of the Dirac operator is bounded from below by a topological quantity depending only on M and χ. We show that for generic metrics on M this bound is attained.
