description: One of the important problems in multiprocessor systems is Task Graph Scheduling. Task Graph Scheduling is an NP-Hard problem. Both learning automata and genetic algorithms are search tools which are used for solving many NP-Hard problems. In this paper a new hybrid method based on Genetic Algorithm and Learning Automata is proposed. The proposed algorithm begins with an initial population of randomly generated chromosomes and after some stages, each chromosome maps to an automaton. Experimental results show that superiority of the proposed algorithm over the current approaches.
SCALE-FREE COOPERATIVE CONTROL OF MULTI-AGENT SYSTEMS
Creators: name: Nojavanzadeh, Donya
Publisher: name: Washington State University
Year: 2021

description: The synchronization problem of multi-agent systems (MAS) has become a hot topic among researchers in recent years. Cooperative control of MAS is used in practical applications such as robot networks, autonomous vehicles, distributed sensor networks, swarming, flocking, and others. The objective of synchronization is to secure an asymptotic agreement on a common state or output trajectory by local interaction among agents.
description: Two classes of multi-agent systems have been identified: homogeneous (i.e. agents are identical) and heterogeneous (i.e. agents are non-identical). State synchronization inherently requires homogeneous MAS. On the other hand, for a heterogeneous MAS generically, it is more reasonable to consider output synchronization since the dimensions of states and their physical interpretation may be different. In heterogeneous MAS, if the agents have absolute measurements oftheir own dynamics in addition to relative information from the network, they are said to be introspective, otherwise, they are called non-introspective.
description: In practical applications, the network dynamics are not perfect and may be subject to input delays, communication delays, input saturation, and external disturbances. In this dissertation, synchronization, delayed, and almost synchronization of homogeneous and heterogeneous MAS have been studied in various circumstances. An innovative contribution of this dissertation is designing scale-free protocols to obviate the requirement for the knowledge of the communication networks. This feature allows the protocols to effectively work for any MAS regardless of the size of the network and the knowledge of the communication graph such as bounds on the spectrum of the associated Laplacian matrix and the number of agents.

description: A new ONO-tridentate Schiff base ligand (H2L) derived by the condensation of nicotinic hydrazide with 5-chlorosalicylaldehyde has been prepared and characterized by combustion analysis (CHN), FT-IR and multinuclear (1H and 13C) NMR spectroscopy. The crystalline nature and molecular structure of the ligand were confirmed by single-crystal X-ray diffraction analysis. Furthermore, the optimized structural parameters of the four possible configurations of the ligand including Z and E stereoisomers each containing two tautomeric forms (enol and keto) have also been investigated. The theoretical parameters were calculated by performing the DFT method using the B3LYP/Def2-TZVP level of theory. In addition to this, dioxomolybdenum(VI) (MoO2L) and oxovanadium(V) (VOL) complexes with the entitled Schiff base ligand have also been prepared and characterized by different techniques. Then, the catalytic efficiencies of synthesized VOL and MoO2L complexes were also explored for the oxidation of sulfides using 30% aqueous H2O2 as a source of oxygen. These homogeneous catalysts showed excellent catalytic activities in the oxidation of both aromatic and aliphatic sulfides.

Gold Rush

description: In 1861, news had spread of a potential motherlode of gold in the distant Cariboo region of the British North American Colony of British Columbia. This rush followed on the heels of the colony’s Fraser Gold Rush only a few years earlier. As the Fraser Gold Rush dwindled, some prospectors did not given up their chances and figured gold in large quantities could be found further upstream. So, they packed their things north, prospecting along the way but it was not until they reached Horsefly River in the Cariboo Region that considerable quantities of gold paid out. Eventually, news spread and men flocked to the region spreading out to the various creeks to try their chances to strike it rich. However, these gold miners not only rushed to the Cariboo region for gold, but some also sought adventure to prove a distinct martial masculinity that freed them of middle-class values. The harsh wilderness of the Cariboo provided the opportunity to engage in perceived masculine qualities of physical strength, domination, courage, and valor deemed true manliness. Partaking in the Gold Rush allowed miners to prove their manhood and escape from concepts of restrained manhood usually associated with middle-class values. However, the transformation from restrained man to marital man was usually incomplete creating a fluid gender identity in the formative years of British Columbia that desired masculine independence but valued domesticity. Within these communities dominated by men seeking a martial identity in the gold field economies grew that profited off of miners. Saloons, wayside houses, boarding houses, swindlers, and merchants could easily make a quick buck off of men seeking adventure in the Cariboo mines. The Cariboo Gold Rush eventually slowed until its accepted conclusion in 1867 with many formerly booming towns in the Cariboo left with dramatically reduced populations as many men left the Colony. It was not until the completion of the Canadian Pacific Railway in the mid-1880s that British Columbia achieved a substantial white settler population.
Investigation of novel signals induced by lipopolysaccharide in innate immune cells
Creators: name: Duncan, Sherie Kristina
Publisher: name: University of British Columbia

description: Macrophages play key roles in innate immune responses. They phagocytose and destroy bacteria, and are activated by various microbial products, recognized through a variety of pattern recognition receptors, including toll-like receptors (TLRs). Engagement of TLRs triggers various intracellular signals, leading to the release of mediators that help orchestrate both the innate and adaptive immune responses. Deficiency in the ability of the host to detect and respond to bacterial products leads to repeated or chronic infections, whereas excessive responses to bacterial products can lead to septic shock and death. Lipopolysaccharide (LPS) is a major constituent of the cell wall of gram-negative bacteria and a chief contributor to the development of septic shock in infections with gram-negative bacteria. The current paradigm is that all biological responses to LPS from Escherichia coli depend on TLR4. Here, we refute this paradigm and present evidence demonstrating that alternate receptors, in addition to TLR4, transduce signals from LPS in macrophages. Using ultra-pure preparations of LPS, we found that activation of p21Ras and phosphorylation of Akt and Src family kinase targets such as Cbl, Pyk2, Vav and Syk occurred even in absence of TLR4, whereas MAPK activation was completely dependent on TLR4. CD14 and class A (SR-AI/II) and class B (CD36) scavenger receptor members were implicated in TLR4-independent signalling, indicating that these LPS-binding proteins play a greater role in pathogen recognition than previously appreciated. We identified downstream pathways mediated by TLR4-independent signalling that include promotion of cellular viability, changes in cell morphology and induction of gene expression, most notably Il1a and Il1b expression. We also observed changes in leukocyte distribution in TLR4-deficient animals following LPS treatment, confirming that TLR4-independent pathways also function in vivo. We observed that TLR4 signalling negatively regulated the activation of p21Ras and Cbl, indicating that the TLR4-independent and TLR4-dependent pathways influence one another. Furthermore, we found that the negative effect of TLR signalling on p21Ras activation required MAPK activity and also affected cytokine signalling. We propose that the TLR4-independent pathway provides signals that are critical for the development of a global response to infection and may represent a general mechanism for sensing pathogens.

description: Alliances were an important feature of the international system on the eve of World War I. The formation of rival blocs of Great Powers has previously considered a major cause of the outbreak of war in 1914, but this assessment misses the point. Instead of increased rigidity, it was, rather, the uncertainty of the alliances’ cohesion in the face of a ''casus foederis'' that fostered a preference for high-risk crisis management among decision-makers.

description: We present the phase diagram for the current states of superconducting films, based on the experimental investigation of the resistive transition induced by transport current. We found that a rather narrow film never enters the vortex state, but experiences direct transition from the purely superconducting state to the resistive state with phase-slip centers as soon as the current exceeds the Ginzburg-Landau critical current Ic. The Meissner current state of the films of intermediate width transforms at I > 0.8Ic to the vortex resistive state which exists within the current interval 0.8Ic < I < Im, where the value Im of the upper critical current is in a good agreement with the theory. The vortex state of wide films is realized within the current region I^{AL} < I < Im, where I^{AL} is the transition point to the vortex state by Aslamazov and Lempitskiy. At I>Im, the wide films enter a vortex-free resistive state with phase-slip lines.

description: Successfully deploying advances in technology and science was crucial to gaining a winning edge in World War I. Over the course of the war, the Ottoman military, often assisted by their German allies, invested substantial resources in increasing the empire’s technological capacities. The army made considerable headway in expanding infrastructure and building an air force – projects involving feats of engineering they often documented and circulated using the latest technology in photography and film. Nonetheless, some major projects, such as the railway, remained incomplete until the war’s end, undermining the army’s capacity to fully exploit such technological achievements.

description: We address the problem of inferring a speaker's level of certainty based on prosodic information in the speech signal, which has application in speech-based dialogue systems. We show that using phrase-level prosodic features centered around the phrases causing uncertainty, in addition to utterance-level prosodic features, improves our model's level of certainty classification. In addition, our models can be used to predict which phrase a person is uncertain about. These results rely on a novel method for eliciting utterances of varying levels of certainty that allows us to compare the utility of contextually-based feature sets. We elicit level of certainty ratings from both the speakers themselves and a panel of listeners, finding that there is often a mismatch between speakers' internal states and their perceived states, and highlighting the importance of this distinction.

Dorsal aspect with prominent transverse keel connecting to smaller, ventrally directed triangular keel on meson; basal ear lobes form a pair of small shelf-like projections (Fig. 5). Right hook and base of aedeagus are broken but are stored in the abdominal tip of the specimen. Female. Unknown. Larva. Unknown. Etymology. The species name, used as a noun in apposition, is based on the type locality in Farallones de Citará. Diagnosis. This species is similar to A. albimacula Klapálek and A. rugosa Stark in general aedeagal structure (Stark et al. 1999; Stark 2001). The former species has a distinctive clear “window” at the cord in the wing pigment pattern and the aedeagus lacks the smaller, basal ear lobes, whereas the latter species has the lateral ear lobes projecting beyond the mesoapical lobe (see Fig. 99 in Stark 2001).

description: We show that lattice mismatched bilayer graphene can realize robust one-dimensional wires. By considering a single domain wall where the masses of the Dirac electrons change their sign, we establish a general projection principle. This determines how the existence of topological zero-energy domain wall states depends on the direction of the domain wall and locations of the massive Dirac cones inside the bulk Brillouin zone. We generalize this idea for arbitrary patterns of domain walls, showing that the topologically protected states exist only in the presence of an odd number of topological domain walls.

description: The question under what conditions different witnesses may detect some entangled states simultaneously is answered for both finite- and infinite-dimensional bipartite systems. Finite many different witnesses can detect some entangled states simultaneously if and only if their convex combinations are still witnesses; they can not detect any entangled state simultaneously if and only if the set of their convex combinations contains a positive operator. For two witnesses $W_1$ and $W_2$, some more can be said: (1) $W_1$ and $W_2$ can detect the same set of entangled states if and only if they are linearly dependent; (2) $W_2$ can detect more entangled states than that $W_1$ can if and only if $W_1$ is a linear combination of $W_2$ and a positive operator. As an application, some characterizations of the optimal witnesses are given and some structure properties of the decomposable optimal witnesses are presented.

description: The standard picture of planet formation posits that giant gas planets are over-grown rocky planets massive enough to attract enormous gas atmospheres. It has been shown recently that the opposite point of view is physically plausible: the rocky terrestrial planets are former giant planet embryos dried of their gas "to the bone" by the influences of the parent star. Here we provide a brief overview of this "Tidal Downsizing" hypothesis in the context of the Solar System structure.

Depending on structural and energetic properties of the substrate, we find different adsorbed polymer conformations, amongst which are spherical droplets attached to the wire and monolayer tubes surrounding it. We identify adsorption temperatures and the type of the transition between adsorbed and desorbed structures depending on the substrate attraction strength.

description: Tin sulfide (SnS) nanoparticles were prepared from tin(II) dithiocarbamate single source precursors. Powder X-ray diffraction patterns of the SnS nanoparticles confirmed orthorhombic herzenbergite phase of tin sulfide. High-resolution transmission electron microscope images show spherically shaped tin sulfide with particles size in the range 1.0–2.8 nm. The bandgap energy obtained from Tauc plots is in the range 2.95–3.32 eV. The as-prepared SnS nanoparticles were used as nano photocatalysts for the degradation of brilliant green (BG), crystal violet (CV), methylene blue (MB) and methyl red (MR) under visible light irradiation. The degradation efficiency of BG by the SnS nanoparticles after 180 min irradiation are 76%, 81% and 70% by SnS-1, SnS-2 and SnS-3. Degradation efficiency of 66%, 90% and 75% were obtained for SnS-1, SnS-2 and SnS-3, respectively, against CV dye. While the efficiency of 79%, 97% and 93% were obtained for SnS-1, SnS-2 and SnS-3, respectively, against MB dye. The results showed that the as-prepared SnS nanoparticles are efficient photocatalyst for the degradation of BG, CV, MB and MR dyes. Liquid chromatography-mass spectrometry was used to investigate the degradation pathway of the organic dyes. The effects of irradiation time, scavengers and photostability on the photocatalysis process were also evaluated.

description: We present the results of a study of stellar population properties at large galactocentric radii of 14 low-mass early-type galaxies in the Fornax and Virgo clusters. We derive radial profiles of Age, total metallicity [Z/H], and [alpha/Fe] abundance ratios out to 1 - 3 effective radii by using nearly all of the Lick/IDS absorption-line indices in comparison to recent single stellar population models. We extend our study to higher galaxy mass via a novel literature compilation of 37 early-type galaxies, which provides stellar population properties out to one effective radius. We find that metallicity gradients correlate with galactic mass, and the relationship shows a sharp change in slope at a dynamical mass of 3.5 10^10 M_{sun}. The central and mean values of the stellar population parameters (measured in r < r_e/8, and at r = r_e, respectively) define positive mass trends. We suggest that the low metallicities, almost solar [alpha/Fe] ratios and the tight mass-metallicity gradient relation displayed by the low-mass galaxies are indicative of an early star-forming collapse with extended (i.e., > 1 Gyr), low efficiency star formation, and mass-dependent galactic outflows of metal-enriched gas. The flattening of metallicity gradients in high-mass galaxies, and the broad scatter of the relationship are attributed to merger events. The high metallicities and supersolar abundances shown by these galaxies imply a rapid, high efficiency star formation. The observed [Z/H]--mass and [alpha/Fe]--mass relationships can be interpreted as a natural outcome of an early star-forming collapse. However, we find that hierarchical galaxy formation models implementing mass-dependent star formation efficiency, varying IMF, energy feedback via AGN, and the effects due to merger-induced starbursts can also reproduce both our observed relationships.

description: Herein, a novel refractory Nb30Mo30Ti20Co20 (at. %) high-entropy superalloy (RHESA) is introduced. Annealing at 1200 °C led to the precipitation of a semi-coherent individual (Co, Ti)-rich B2, (Ti, O)-rich fcc (Ti-rich oxides), and hierarchical B2 + fcc nanoparticles in the (Nb, Mo)-rich RHESA bcc phase. B2 + fcc dispersoids were dominant, and they nucleated heterogeneously because of the coherency ensured by the Baker–Nutting orientation relationship. The emergence of multi-type nanoprecipitates doubled the room-temperature compressive ductility without sacrificing strength. Our study can solve a chief problem of current RHESAs—the low stability of B2 dispersoids at T > 700 °C. Multi-type B2, fcc, and B2 + fcc nanoprecipitates balancing mechanical properties of the refractory Nb30Mo30Ti20Co20 high-entropy superalloy (RHESA) endow new prospects for application of RHESAs at T ≥ 1200 °C.

description: The near-threshold 12C (0^+_2) resonance provides unique possibility for fast helium burning in stars, as predicted by Hoyle to explain the observed abundance of elements in the Universe. Properties of this resonance are calculated within the framework of the alpha-cluster model whose two-body and three-body effective potentials are tuned to describe the alpha - alpha scattering data, the energies of the 0^+_1 and 0^+_2 states, and the 0^+_1-state root-mean-square radius. The extremely small width of the 0^+_2 state, the 0_2^+ to 0_1^+ monopole transition matrix element, and transition radius are found in remarkable agreement with the experimental data. The 0^+_2-state structure is described as a system of three alpha-particles oscillating between the ground-state-like configuration and the elongated chain configuration whose probability exceeds 0.9.
Wireless MEMS drug delivery device enabled by a micromachined Nitinol actuator as a pumping mechanism
Creators: name: Fong, Jeffrey Chun Kit
Publisher: name: University of British Columbia
Year: 2015

description: Traditional drug delivery methods utilize systemic administration where the medication is circulated through the entire body. These methods require a high dosage at the point of entry in order to reach the therapeutic level at the targeted location and can result in serious side effects. Implantable drug delivery devices can be used to increase efficacy by targeting specific regions in the body and by safely using higher drug concentrations. Microfabrication allows for the creation of these minimally invasive devices to treat conditions not previously possible due to the limited amount of space surrounding the target area. Devices with passive releasing mechanisms have been commercialized but ones with active mechanisms are still in the works. In this thesis, a shape memory alloy (SMA) actuator is micromachined into a rectangular, planar coil to perform cantilever-like actuation. The SMA-coil actuator forms a passive resonant circuit that functions as a wireless heat source activated using external radio-frequency (RF) electromagnetic fields. SiO₂ stress layers are selectively patterned on the Nitinol SMA structure to manipulate the cantilever profile at the nominal cold state. RF radiation with varying field frequencies showed strong frequency dependence of wireless heating, actuation displacement, and force generation by several actuators with resonant frequencies of 170-245 MHz. When excited at resonance, these actuators exhibited maximum out-of-plane displacement and force of 215 µm and 71 mN, respectively. The actuator was integrated into a 10.0×10.5×2.1 mm³ polyimide-packaged chip containing a micromachined Parylene-C pump chamber to force the release of the drug from the reservoir by wirelessly activating the actuator. Experimental operation of the prototypes showed successful release of the test agents from devices placed in liquid and excited by radiating tuned RF fields with an output power of 1.1 W. These tests revealed a single release volume of 219 nL, suggesting that the device’s capacity of 76 µL is equivalent to ~350 individual ejections. Thermal behavior of the activated device is also reported in detail. This proof-of-concept prototype validates the effectiveness of wireless RF pumping for fully controlled, long-lasting drug delivery, a key step towards enabling patient-tailored, targeted local drug delivery through highly miniaturized implants.

description: We show that the "cold" Hubble flow observed for galaxies around the Milky Way does not represent a problem in cosmology but is due to the particular geometry and dynamics of our local wall. The behavior of the perturbed Hubble flow around the Milky Way is the result of two main factors: at small scales (R < 1 Mpc) the inflow is dominated by the gravitational influence of the Milky Way. At large scales (R > 1 Mpc) the out flow reflects the expansion of our local wall which "cools down" the peculiar velocities. This is an intrinsic property of walls and is independent of cosmology. We find the dispersion of the local Hubble flow (1 < R < 3 Mpc) around simulated "Milky Way" haloes located at the centre of low-density cosmological walls to be σ_H ~ 30 km/s, in excellent agreement with observations. The expansion of our local wall is also reflected in the value of the measured local Hubble constant. For "Milky Way" haloes inside walls, we find super-Hubble flows with h_local \simeq 0.77 - 1.13. The radius of equilibrium (R_0) depends not only on the mass of the central halo and the Hubble expansion but also on the dynamics given by the local LSS geometry. The super-Hubble flow inside our local wall has the effect of reducing the radius at which the local expansion balances the gravitational influence of the Milky Way. By ignoring the dynamical effect of the local wall, the mass of the Milky Way estimated from R_0 can be underestimated by as much as ~ 30%.

By using some concepts in datawarehouse like slice-dice,drill down and roll up will increase the ability of multidimensional datawarehouse. The research question and the discussing for this paper are how much deepest the multidimensional ability from each fact table in datawarehouse. By using the statistic combination formula we try to explore the combination that can be yielded from each dimension in hypercubes, the entire of dimensi combination, minimum combination and maximum combination.

description: Transition metal diboride-based thin films are promising candidates to replace state-of-the-art protective and functional coating materials due to their unique properties. Here, we focus on hexagonal WB2-z, showing that the AlB2 structure is stabilized by B vacancies exhibiting its energetic minima at sub-stoichiometric WB1.5. Nanoindentation reveals super-hardness of 0001 oriented α-WB2-z coatings, linearly decreasing by more than 15 GPa with predominant 101¯1 orientation. This anisotropy is attributed to differences in the generalized stacking fault energy of basal and pyramidal slip systems, highlighting the feasibility of tuning mechanical properties by crystallographic orientation relations. First report of an anisotropic elastoplastic behaviour in super-hard PVD AlB2 structured WB2-z. Theoretical and experimental verification of thermodynamically most stable sub-stoichiometric α-WB2-z coatings by structural and mechanical analysis.

description: Accurately aligning contextual representations in cross-lingual sentence embeddings is key for effective parallel data mining. A common strategy for achieving this alignment involves disentangling semantics and language in sentence embeddings derived from multilingual pre-trained models. However, we discover that current disentangled representation learning methods suffer from semantic leakage - a term we introduce to describe when a substantial amount of language-specific information is unintentionally leaked into semantic representations. This hinders the effective disentanglement of semantic and language representations, making it difficult to retrieve embeddings that distinctively represent the meaning of the sentence. To address this challenge, we propose a novel training objective, ORthogonAlity Constraint LEarning (ORACLE), tailored to enforce orthogonality between semantic and language embeddings. ORACLE builds upon two components: intra-class clustering and inter-class separation. Through experiments on cross-lingual retrieval and semantic textual similarity tasks, we demonstrate that training with the ORACLE objective effectively reduces semantic leakage and enhances semantic alignment within the embedding space.

The cultural transmission of morals : a case study of Western visitors to Cambodia's genocide museums
Creators: name: Ivanova, Lily
Publisher: name: University of British Columbia
Year: 2015

description: The “new” sociology of morality has issued a call for research. This revival movement has focused on combining findings in cultural sociology with new findings in cognitive science to identify morality as a “cultural schema” or habitus-like framework which shapes individual action. While invaluable, this research addresses only half of the equation. In line with previous theoretical work in cultural sociology, this paper endeavours to examine both the production and consumption processes through which morality is transmitted. The paper relies on data from an empirical study of visitor experiences to two genocide museums in Phnom Penh, Cambodia. Material from both museums was analyzed to find two parallel narratives of genocide running through the museums : an emphasis on the universal nature of the genocide to appeal to international visitors, and an account of the particularities of the genocide to serve domestic political goals. To trace the reception of the museum claims, 45 in-depth interviews with Western visitors were analyzed. I found four “types” of experiences at the museums based on different ways visitors incorporated new information about the genocide into their existing schemas : firm universalism, push-over universalism, adamant relativism and new converts to relativism. While the majority of visitors had stable experiences, reinforcing pre-existing “schemas” (moral frameworks) of universalism or relativism, some visitors did have transformative experiences, where information about the Cambodian genocide overhauled existing schemas of genocide. Beyond the sociology of morality, these findings hold significant implication for globalization studies. What political implications do stable and transformative moral experiences at genocide museums have for genocide?

description: Let $R$ be a discrete valuation ring with fraction field $K$ and with algebraically closed residue field of positive characteristic $p$. Let $X$ be a smooth fibered surface over $R$ with geometrically connected fibers endowed with a section $x\in X(R)$. Let $G$ be a finite solvable $K$-group scheme and assume that either $|G|=p^n$ or $G$ has a normal series of length 2. We prove that every quotient pointed $G$-torsor over the generic fiber $X_η$ of $X$ can be extended to a torsor over $X$ after eventually extending scalars and after eventually blowing up $X$ at a closed subscheme of its special fiber $X_s$.

Likelihood based reconstruction algorithm for finding short tracks within the T2K experiment's fine-grained detectors
Creators: name: McCarthy, Mark John
Publisher: name: University of British Columbia
Year: 2015

description: The T2K experiment is a long baseline neutrino experiment. Rates of different types of neutrino interactions are compared at a near detector and a detector 295 km from the neutrino source which enables neutrino oscillation and cross-section measurements. Understanding the activity near the neutrino interaction vertex in the near detector is crucial to identifying how a neutrino interacted. Current reconstruction algorithms for T2K's Fine Grained Detectors (FGD) have a decreased sensitivity to short tracks (<200mm) such as those created by low energy protons and pions. A new likelihood based reconstruction algorithm entitled FLikFit (FGD Likelihood Fitter) has been written that uses information from the deposited charge and the position of the hits within the FGDs in an attempt to tag these particles. It traces a predicted path of the particle through the detector and calculates expected kinetic energy and path length values which are fed to an existing probability distribution function to obtain a likelihood for each scintillator bar. The fitter is seen to calculate likelihoods effectively and proves to be adept at hypothesis testing, but further development is required to improve the FLikFit's ability to converge.

description: Anacroneuria tunasi sp. nov., Stark & Zúñiga (Figs. 32-36) Material examined. Holotype ♂ from COLOMBIA, Risaralda, Municipio de Santuario, Parque Nacional Natural Tatamá, 2400 m, November 2004, on vegetation, J. Castellanos (MEUV). Adult habitus. General color yellow brown patterned with brown, head yellow brown with dusky brown area from ocelli to forward of M-line; M-line represented by oval median spot (Fig. 32). Pronotum with irregular dark lateral bands and wide median pale band. Wing membrane with pale brown tint and brown veins, R vein darkest. Femora dark on dorsum and in narrow apical band; tibia uniformly dark brown. Male. Forewing length 12 mm. Hammer thimble shaped, height subequal to basal diameter (Fig. 33). Aedeagal apex trilobed with shoulders projecting as ear-like structures (Fig. 34); dorsal keel a minute triangular projection (Fig. 36). Apical area in lateral aspect about as wide as long; ear-like lateral lobes reach beyond midpoint to ventral margin (Fig. 35). Female. Unknown. Larva. Unknown. Etymology. The species name, used as a noun in apposition, honors the indigenous people who inhabited this region in Colombia. Diagnosis. The aedeagus of this species is similar to that of A. citara (described above) and related species. It differs from the related species (A. albimacula and A. rugosa) on the same basis as A. citara, and it differs from that species in having a much smaller apical aedeagal area, in the absence of small basal ear lobes and in the sinuate dorsal connection of the lateral ear lobes to the apex. In A. citara this connection is more linear (Fig. 36). Ecological notes. The specimen was collected near the type locality of A. tatama. This National Natural Park is one of the best protected areas in Colombia and is located in the west part of Región Natural Andina in an area with rugged topography.

The targum (1875:Apr.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1875

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Extreme shock models: an alternative perspective

description: Extreme shock models have been introduced in Gut and Hüsler (1999) to study systems that at random times are subject to shock of random magnitude. These systems break down when some shock overcomes a given resistance level. In this paper we propose an alternative approach to extreme shock models using reinforced urn processes. As a consequence of this we are able to look at the same problem under a Bayesian nonparametric perspective, providing the predictive distribution of systems' defaults.
