description: The precise astrometric observation of small near-Earth objects (NEOs) is an important observational research topic in the astrometric discipline, which greatly promotes multidisciplinary research, such as the origin and evolution of the solar system, the detection and early warning of small NEOs, and deep-space navigation. The characteristics of small NEOs, such as faintness and fast moving speed, restrict the accuracy and precision of their astrometric observations. In the paper, we present a method to improve the accurate and precise astrometric positions of NEOs based on image fusion technique. The noise analysis and astrometric test from the observed images of the open cluster M23 are given. Using the image fusion technique, we obtain the sets of superimposed images and original images containing reference stars and moving targets respectively. The final fused image set includes background stars with high signal-to-noise ratios and ideal NEO images simultaneously and avoids the saturation of background stars. Using the fused images, we can reduce the influence of telescope tracking and NEO ephemeris errors on astrometric observations, and our results indicate that the accuracy and precision of NEO Eros astrometry are improved obviously after we choose suitable image fuse mode.

description: Resistance to macrolide antibiotics is conferred by mutation of A2058 to G or methylation by Erm methyltransferases of the exocyclic N6 of A2058 (E. coli numbering) that forms the macrolide binding site in the 50S subunit of the ribosome. Ketolides such as telithromycin mitigate A2058G resistance yet remain susceptible to Erm-based resistance. Molecular details associated with macrolide resistance due to the A2058G mutation and methylation at N6 of A2058 by Erm methyltransferases were investigated using empirical force field-based simulations. To address the buried nature of the macrolide binding site, the number of waters within the pocket was allowed to fluctuate via the use of a Grand Canonical Monte Carlo (GCMC) methodology. The GCMC water insertion/deletion steps were alternated with Molecular Dynamics (MD) simulations to allow for relaxation of the entire system. From this GCMC/MD approach information on the interactions between telithromycin and the 50S ribosome was obtained. In the wild-type (WT) ribosome, the 2′-OH to A2058 N1 hydrogen bond samples short distances with a higher probability, while the effectiveness of telithromycin against the A2058G mutation is explained by a rearrangement of the hydrogen bonding pattern of the 2′-OH to 2058 that maintains the overall antibiotic-ribosome interactions. In both the WT and A2058G mutation there is significant flexibility in telithromycin's imidazole-pyridine side chain (ARM), indicating that entropic effects contribute to the binding affinity. Methylated ribosomes show lower sampling of short 2′-OH to 2058 distances and also demonstrate enhanced G2057-A2058 stacking leading to disrupted A752-U2609 Watson-Crick (WC) interactions as well as hydrogen bonding between telithromycin's ARM and U2609. This information will be of utility in the rational design of novel macrolide analogs with improved activity against methylated A2058 ribosomes. © 2013 Small et al.

description: Background:Ethanol is a toxin responsible for the neurodevelopmental deficits of Fetal Alcohol Spectrum Disorders (FASD). Recent evidence suggests that ethanol modulates the protein expression of lineage specifier transcription factors Oct4 (Pou5f1) and Sox2 in early stages of mouse embryonic stem (ES) cell differentiation. We hypothesized that ethanol induced an imbalance in the expression of Oct4 and Sox2 in early differentiation, that dysregulated the expression of associated and target genes and signaling molecules and diverted cells from neuroectodermal (NE) formation.Methodology/Principal Findings:We showed modulation by ethanol of 33 genes during ES cell differentiation, using high throughput microfluidic dynamic array chips measuring 2,304 real time quantitative PCR assays. Based on the overall gene expression dynamics, ethanol drove cells along a differentiation trajectory away from NE fate. These ethanol-induced gene expression changes were observed as early as within 2 days of differentiation, and were independent of cell proliferation or apoptosis. Gene expression changes were correlated with fewer βIII-tubulin positive cells of an immature neural progenitor phenotype, as well as a disrupted actin cytoskeleton were observed. Moreover, Tuba1a and Gapdh housekeeping genes were modulated by ethanol during differentiation and were replaced by a set of ribosomal genes with stable expression.Conclusions/Significance:These findings provided an ethanol-response gene signature and pointed to the transcriptional dynamics underlying lineage imbalance that may be relevant to FASD phenotype. © 2013 Sánchez-Alvarez et al.
The effect of rezonings on property values : a theoretical and empirical examination of the taxation of land value increments attributable to rezonings in the City of Vancouver, B.C.
Creators: name: Tunnicliffe, Kenneth William
Publisher: name: University of British Columbia

description: In any well-developed urban area where building sites are in relative inelastic supply, rezonlngs from one type of permitted land use to another become an important factor In the supply of urban sites. As a result, rezonings can favorably or adversely affect land values depending upon the type of rezoning. Aside from Federal capital gains legislation, no other taxation legislation attempts to tax away property value increases that result from rezonings, the increases accruing to property owners or developers, not necessarily through any direct action of their own. Since, in Vancouver, the power to rezone is at the discretion of the Vancouver City Council, this increase in value is a result of public policy and could therefore be taxed accordingly. It is the purpose of this thesis to examine the theoretical, historical, and empirical aspects of the taxation of land value increments that result from rezonings. The term which is used throughout the thesis to denote such a taxation scheme is "betterment levy", a term consistent with much of the literature on the subject, especially that of British origin. Based upon a background of urban land theory and the practical legislative experiences of other areas, notably the United Kingdom, an empirical analysis is carried out on the effects of rezoning on land values in the City of Vancouver. A total of 529 properties were selected for study which represent 267 properties of various types which were rezoned during the period 1966-1972 and, as a control group, 262 properties which were not affected by rezonings during the same time period. Assessed values, using the general roll, which are available for each property and which are adjusted to reflect non-arm's length property transactions were used as the value base. "The statistical technique employed for data analysis was regression analysis. Essentially three analyses were undertaken: to determine the relationship between assessed and market values, to determine the overall effects of rezoning on property values, and to determine the effect of specific types of rezoning on value. Basically, the results showed a close relationship between assessed and market values, the overall importance of rezonings on property value, and, most significantly, the importance of the specific type of rezoning on value. Finally, the implications of these findings and the recommendations and limitations derived therefrom are presented as a guide to policy-makers in applying the results to possible policy decisions.

description: In ambito oncologico il dolore affligge la maggior parte dei pazienti (incidenza riportata dal 53 al 90%), in tutte le fasi della malattia: nonostante l’esistenza di Linee Guida (OMS), l’attuale “undertreatment” del sintomo dolore oncologico, legato a un inappropriato uso degli oppioidi, in Italia raggiunge stime fino al 40% dei casi. Segnalazioni recenti  sul consumo degli oppioidi in Italia riportano un aumento imputabile a un solo farmaco (fentanil TTS), il che suggerisce un comportamento prescrittivo inappropriato.
Letteratura in merito alle valutazioni di efficacia delle terapie di controllo  del dolore sia in fase iniziale – quando la terapia medica oncologica è attiva- sia in fase avanzata di malattia – quando il controllo del dolore si configura come una delle principali terapie di supporto-  è ormai disponibile , con un buon livello di affidabilità. Quello che è necessario è aumentare la capacità del Servizio Sanitario   di trasferire nella pratica clinica e assistenziale i risultati della ricerca sulla efficacia delle cure. 
 Questi i quesiti ai quali la ricerca ha inteso rispondere:
a.	Le competenze globalmente espresse dal servizio sanitario dell’Emilia Romagna sono adeguate per consentire un tempestivo, globale, appropriato ed efficace controllo del dolore oncologico, in tutte le fasi della malattia e lungo tutto il percorso di assistenza si a domiciliare che ospedaliero, per tutti i malati che ne hanno bisogno?
b.	Quali raccomandazioni possiamo fornire, basate sulle evidenze di efficacia, a clinici e gestori per migliorare l’identificazione del bisogno, la scelta del trattamento, il suo monitoraggio, la possibilità di garantirne l’accesso e la disponibilità non solo in ospedale ma anche a domicilio?
c.	Quale efficacia hanno dimostrato i percorsi di formazione relativi al riconoscimento e al controllo del dolore messi in atto finora?
d.	Quali percorsi possono essere raccomandati per mettere a disposizione dei cittadini le conoscenze scientifiche sul controllo del dolore oncologico?

description: Requirements engineering process intends to obtain software services and constraints. This process is essential to meet the customer's needs and expectations. This process includes three main activities in general. These are detecting requirements by interacting with software stakeholders, transferring these requirements into a standard document, and examining that the requirements really define the software that the client needs. Functional requirements are services that the software should deliver to the end-user. In addition, functional requirements describe how the software should respond to specific inputs, and how the software should behave in certain circumstances. This paper aims to develop a software requirements specification document of the electronic IT news magazine system. The electronic magazine provides users to post and view up-to-date IT news. Still, there is a lack in the literature of comprehensive studies about the construction of the electronic magazine software specification and design in conformance with the contemporary software development processes. Moreover, there is a need for a suitable research framework to support the requirements engineering process. The novelty of this paper is the construction of software specification and design of the electronic magazine by following the Al-Msie'deen research framework. All the documents of software requirements specification and design have been constructed to conform to the agile usage-centered design technique and the proposed research framework. A requirements specification and design are suggested and followed for the construction of the electronic magazine software. This study proved that involving users extensively in the process of software requirements specification and design will lead to the creation of dependable and acceptable software systems.

description: We present a novel gravitational wave detection algorithm that conducts a matched filter search stochastically across the compact binary parameter space rather than relying on a fixed bank of template waveforms. This technique is competitive with standard template-bank-driven pipelines in both computational cost and sensitivity. However, the complexity of the analysis is simpler allowing for easy configuration and horizontal scaling across heterogeneous grids of computers. To demonstrate the method we analyze approximately one month of public LIGO data from July 27 00:00 2017 UTC - Aug 25 22:00 2017 UTC and recover eight known confident gravitational wave candidates. We also inject simulated binary black hole (BBH) signals to demonstrate the sensitivity.

Residential developer behaviour in British Columbia
Creators: name: Ulinder, Daniel Derek
Publisher: name: University of British Columbia

description: The form and scale of our urban landscape is the net result of an evolutionary process in which there are countless numbers of participants. Societal ambitions and desires are translated subject to a number of constraints, to demands for various qualities and quantities of consumer goods. One of these goods is housing services - the service rendered by the occupation of, or associated with the ownership of, residential real property. This demand gives impetus to the production sector, the residential development industry, whose members, as entrepreneurs, devote their time and energy in an effort to transform these unsatisfied desires into compensation for their activity. The aggregate response of developers, whether they are catering to residential, commercial or retail real estate markets, taken over a period of time, lays the fundamental framework upon which our urban centers grow. As Kaiser notes; "In spite of the key role played by the residential developer in the conversion of open land to urban residential use, he has been relatively ignored by investigators of residential growth in the urban spatial structure." (Kaiser, 1968, p. 351.) It is hoped that this paper, through a micro level investigation of the decision-making process of the suppliers of residential real estate, will lead to an improved understanding of the operation of the real estate market as a whole. Ultimately such research should strengthen the platform upon which housing research and subsequent policy is conducted. This report is based upon information gathered by means of a questionnaire administered to 140 residential developers operating in the province of British Columbia in the three year period preceeding January 1975. The questionnaire was divided into 7 sections designed to gain insight in the following general areas: 1. General characteristics of development firms; 2. Elements of multiple unit development; 3. Elements of single unit development; 4. The role of land use contracts in residential development; 5. The subdivision process; 6. Stages and components of the residential development process; 7. The financing of residential development. Based on the responses of developers included in the study and the analytical framework detailed in Section 2.4 of this report, a number of conclusions were drawn with respect to developer behaviour and the operation of the market. Implications of current trends in the residential development industry are discussed and policy suggestions are made.

description: Hyaline cartilage and mechanically inferior fibrocartilage consisting of mixed collagen types are frequently found together in repairing articular cartilage. The present study seeks to develop methodology to identify collagen type and other tissue components using Fourier transform infrared (FTIR) spectral evaluation of matrix composition in combination with multivariate analyses. FTIR spectra of the primary molecular components of repair cartilage, types I and II collagen, and aggrecan, were used to develop multivariate spectral models for discrimination of the matrix components of the tissues of interest. Infrared imaging data were collected from bovine bone, tendon, normal cartilage, meniscus and human repair cartilage tissues, and composition predicted using partial least squares analyses. Histology and immunohistochemistry results were used as standards for validation. Infrared fiber optic probe spectral data were also obtained from meniscus (a tissue with mixed collagen types) to evaluate the potential of this method for identification of collagen type in a minimally-invasive clinical application. Concentration profiles of the tissue components obtained from multivariate analysis were in excellent agreement with histology and immunohistochemistry results. Bone and tendon showed a uniform distribution of predominantly type I collagen through the tissue. Normal cartilage showed a distribution of type II collagen and proteoglycan similar to the known composition, while in repair cartilage, the spectral distribution of both types I and II collagen were similar to that observed via immunohistochemistry. Using the probe, the outer and inner regions of the meniscus were shown to be primarily composed of type I and II collagen, respectively, in accordance with immunohistochemistry data. In summary, multivariate analysis of infrared spectra can indeed be used to differentiate collagen type I and type II, even in the presence of proteoglycan, in connective tissues, using both imaging and fiber optic methodology. This has great potential for clinical in situ applications for monitoring tissue repair. © 2013 Hanifi et al.

description: In this work we show that bipartite quantum states with local Hilbert space dimension n can violate a Bell inequality by a factor of order $\sqrt{n}$ (up to a logarithmic factor) when observables with n possible outcomes are used. A central tool in the analysis is a close relation between this problem and operator space theory and, in particular, the very recent noncommutative $L_p$ embedding theory. As a consequence of this result, we obtain better Hilbert space dimension witnesses and quantum violations of Bell inequalities with better resistance to noise.

description: Transportation networks, from bicycle paths to buses and railways, are the backbone of urban mobility. In large metropolitan areas, the integration of different transport modes has become crucial to guarantee the fast and sustainable flow of people. Using a network science approach, multimodal transport systems can be described as multilayer networks, where the networks associated to different transport modes are not considered in isolation, but as a set of interconnected layers. Despite the importance of multimodality in modern cities, a unified view of the topic is currently missing. Here, we provide a comprehensive overview of the emerging research areas of multilayer transport networks and multimodal urban mobility, focusing on contributions from the interdisciplinary fields of complex systems, urban data science, and science of cities. First, we present an introduction to the mathematical framework of multilayer networks. We apply it to survey models of multimodal infrastructures, as well as measures used for quantifying multimodality, and related empirical findings. We review modelling approaches and observational evidence in multimodal mobility and public transport system dynamics, focusing on integrated real-world mobility patterns, where individuals navigate urban systems using different transport modes. We then provide a survey of freely available datasets on multimodal infrastructure and mobility, and a list of open source tools for their analyses. Finally, we conclude with an outlook on open research questions and promising directions for future research.

description: 1) Background: The most common methods to evaluate clarithromycin resistance is the E-Test, but is time consuming. Resistance of Hp to clarithromycin is due to point mutations in the 23S rRNA.
Eight different point mutations have been related to CH resistance, but the large majority of the clarithromycin resistance depends on three point mutations (A2142C, A2142G and A2143G).
A novel PCR-based clarithromycin resistance assays, even on paraffin-embedded biopsy specimens, have been proposed.
Aims: to assess clarithromycin resistance detecting these point mutation (E-Test as a reference method);secondly, to investigate relation with MIC values.
Methods: Paraffin-embedded biopsies of patients Hp-positive were retrieved. The A2142C, A2142G and A2143G point mutations were detected by molecular analysis after DNA extraction by using a TaqMan real-time PCR.
Results: The study enrolled 86 patients: 46 resistant and 40 sensible to CH. The Hp status was evaluated at endoscopy, by rapid urease test (RUT), histology and hp culture. According to real-time PCR,  37 specimens were susceptible to clarithromycin (wild type dna) whilst the remaining  49 specimens (57%) were resistant. A2143G is the most frequent mutation. A2142C always express a resistant phenotype and A2142G leads to a resitant phenotype only if homozigous.

2) Background: Colonoscopy work-load for endoscopy services is increasing due to colorectal cancer prevention. We tested a combination of faecal tests to improve accuracy and prioritize the access to colonoscopy.
Methods: we tested a combination of fecal tests (FOBT, M2-PK and calprotectin) in a group of 280 patients requiring colonoscopy.
Results: 47 patients had CRC and 85 had advanced adenoma/s at colonoscopy/histology. In case of single test, for CRC detection FOBT was the test with the highest specificity and PPV, M2-PK had the highest sensitivity and higher NPV.  
Combination was more interesting in term of PPV. And the best combination of tests was i-FOBT + M2-PK.

description: We describe a novel method to use a scintillating fiber detector similar to the Fast Annihilation Cryogenic Tracking (FACT) used at the antimatter experiment AEgIS to monitor the presence of ortho-positronium. A single scintillating fiber was coupled to a photomultiplier tube and irradiated by flashes of about $6\cdot10^6$ $511\,\text{keV}$ $γ$-rays produced by $\approx10\,\text{ns}$ long positron pulses. The results were used to demonstrate the ability to track the creation and annihilation of ortho-positronium atoms over time in cryogenic and highly magnetic environments by using the FACT detector as a "digital calorimeter".

description: In laboratory experiments we determine the mass gain and loss in central collisions between cm to dm-size SiO2 dust targets and sub-mm to cm-size SiO2 dust projectiles of varying mass, size, shape, and at different collision velocities up to ~56.5 m/s. Dust projectiles much larger than 1 mm lead to a small amount of erosion of the target but decimetre targets do not break up. Collisions produce ejecta which are smaller than the incoming projectile. Projectiles smaller than 1 mm are accreted by a target even at the highest collision velocities. This implies that net accretion of decimetre and larger bodies is possible. Independent of the original size of a projectile considered, after several collisions all fragments will be of sub-mm size which might then be (re)-accreted in the next collision with a larger body. The experimental data suggest that collisional growth through fragmentation and reaccretion is a viable mechanism to form planetesimals.

description: We present our analysis of the three HII-buried-AGN: SDSS J091053+333008, SDSS J121837+091324, and SDSS J153002-020415, by studying their optical spectra extracted from SDSS. The location in the BPT diagnostic diagrams of the three galaxies indicates that the narrow emission lines are mainly exited from HII regions. However, after the removal of the host galaxy's stellar emission, the emission lines display the typical feature of Narrow-line Seyfert 1-like. All of the three objects have large Eddington ratio, small black hole mass, and low star formation rate. We propose that the three galaxies are at the transit stage from the starburst-dominated phase to AGN-dominated phase.

description: Wireless Body Area Network (WBAN) ensures high-quality healthcare services by endowing distant and continual monitoring of patients' health conditions. The security and privacy of the sensitive health-related data transmitted through the WBAN should be preserved to maximize its benefits. In this regard, user authentication is one of the primary mechanisms to protect health data that verifies the identities of entities involved in the communication process. Since WBAN carries crucial health data, every entity engaged in the data transfer process must be authenticated. In literature, an end-to-end user authentication mechanism covering each communicating party is absent. Besides, most of the existing user authentication mechanisms are designed assuming that the patient's mobile phone is trusted. In reality, a patient's mobile phone can be stolen or comprised by malware and thus behaves maliciously. Our work addresses these drawbacks and proposes an end-to-end user authentication and session key agreement scheme between sensor nodes and medical experts in a scenario where the patient's mobile phone is semi-trusted. We present a formal security analysis using BAN logic. Besides, we also provide an informal security analysis of the proposed scheme. Both studies indicate that our method is robust against well-known security attacks. In addition, our scheme achieves comparable computation and communication costs concerning the related existing works. The simulation shows that our method preserves satisfactory network performance.

description: Storage systems have not kept the same technology improvement rate as computing systems. As applications produce more and more data, I/O becomes the limiting factor for increasing application performance. I/O congestion caused by concurrent access to storage devices is one of the main obstacles that cause I/O performance degradation and, consequently, total performance degradation. Although task-based programming models made it possible to achieve higher levels of parallelism by enabling the execution of tasks in large-scale distributed platforms, this parallelism only benefited the compute workload of the application. Previous efforts addressing I/O performance bottlenecks either focused on optimizing fine-grained I/O access patterns using I/O libraries or avoiding system-wide I/O congestion by minimizing interference between multiple applications. In this paper, we propose enabling I/O Awareness in task-based programming models for improving the total performance of applications. An I/O aware programming model is able to create more parallelism and mitigate the causes of I/O performance degradation. On the one hand, more parallelism can be created by supporting special tasks for executing I/O workloads, called I/O tasks, that can overlap with the execution of compute tasks. On the other hand, I/O congestion can be mitigated by constraining I/O tasks scheduling. We propose two approaches for specifying such constraints: explicitly set by the users or automatically inferred and tuned during application's execution to optimize the execution of variable I/O workloads on a certain storage infrastructure. Our experiments on the MareNostrum 4 Supercomputer demonstrate that using I/O aware programming model can achieve up to 43% total performance improvement as compared to the I/O non-aware implementation.

description: Diagonal and off-diagonal optical conductivity spectra have been determined form the measured reflectivity and magneto-optical Kerr effect (MOKE) over a broad range of photon energy in the itinerant ferromagnetic phase of CuCr$_2$Se$_4$ at various temperatures down to T=10 K. Besides the low-energy metallic contribution and the lower-lying charge transfer transition at $E$$\approx$2 eV, a sharp and distinct optical transition was observed in the mid-infrared region around $E$$=$0.5 eV with huge magneto-optical activity. This excitation is attributed to a parity allowed transition through the Se-Cr hybridization-induced gap in the majority spin channel. The large off-diagonal conductivity is explained by the high spin polarization in the vicinity of the Fermi level and the strong spin-orbit interaction for the related charge carriers. The results are discussed in connection with band structure calculations.

description: Previous studies found that uninsured and Medicaid insured cancer patients have poorer outcomes than cancer patients with private insurance. We examined the association between health insurance status and survival of New Jersey patients 18-64 diagnosed with seven common cancers during 1999-2004. Hazard ratios (HRs) with 95% confidence intervals for 5-year cause-specific survival were calculated from Cox proportional hazards regression models; health insurance status was the primary predictor with adjustment for other significant factors in univariate chi-square or Kaplan-Meier survival log-rank tests. Two diagnosis periods by health insurance status were compared using Kaplan-Meier survival log-rank tests. For breast, colorectal, lung, non-Hodgkin lymphoma (NHL), and prostate cancer, uninsured and Medicaid insured patients had significantly higher risks of death than privately insured patients. For bladder cancer, uninsured patients had a significantly higher risk of death than privately insured patients. Survival improved between the two diagnosis periods for privately insured patients with breast, colorectal, or lung cancer and NHL, for Medicaid insured patients with NHL, and not at all for uninsured patients. Survival from cancer appears to be related to a complex set of demographic and clinical factors of which insurance status is a part. While ensuring that everyone has adequate health insurance is an important step, additional measures must be taken to address cancer survival disparities.

description: Let $(E,Φ)\rightarrow (X,ω_X)$ be a Higgs bundle over a compact Kähler manifold. We suppose that the holomorphic vector bundle $E$ decomposes into a direct sum of holomorphic line bundles. In this paper, we give the necessary and sufficient condition for the existence of a diagonal metric which is a solution to the Hermitian-Einstein equation. Our theorem can easily be generalized to $G$-Higgs bundles. We also describe the relationship between the stability condition and our condition using the torus action on the space of Higgs fields.

description: In the present study we are using multi variate analysis techniques to discriminate signal from background
in the fully hadronic decay channel of ttbar
events. We give a brief introduction to the role of the Top
quark in the standard model and a general description of the CMS Experiment at LHC. We have used the
CMS experiment computing and software infrastructure to generate and prepare the data samples used in
this analysis. We tested the performance of three different classifiers applied to our data samples and used
the selection obtained with the Multi Layer Perceptron classifier to give an estimation of the statistical and
systematical uncertainty on the cross section measurement.

Abstract:

Geomorphica (http://geomorphica.org) is a community-led and -driven scientific journal that fosters academic discourse and research advances in the field of geomorphology. It is hosted by Penn State University Libraries and supported by the International Association of Geomorphology. Geomorphica adds to the growing family of Diamond Open-Access journals in the Geosciences next to Volcanica, Tektonika, Seismica, and Sedimentologika, offering free public access without subscription fees and article processing charges to promote inclusivity and eliminating barriers in scientific communication. Over the past two years, we have established an initiative with more than 30 volunteers who contribute to all functions including administration, editing, reviewing, typesetting, and visual branding. Geomorphica has been officially launched since June 2023 and is open for manuscript submissions related (but not limited) to landscapes and landforms, Earth’s and planetary near-surface processes, and the mechanisms, dynamics and timescales pertaining to these processes. Experts in related fields are encouraged to join our reviewer database (https://geomorphicaadmin.pythonanywhere.com/), participating in the quality control of scientific advances. To reduce bias, we have developed a triple-anonymous review policy, whereby the authors, reviewers and the associate editor making the recommendation are anonymous to each other. The reviewer’s reports and authors’ rebuttals will become publicly available along with the published articles. In this presentation, we will introduce our diverse editorial board, celebrate our first article submissions, and share our experiences during recent progress. We welcome feedback from the broader community to help us continually improve Geomorphica and look forward to your involvement with the initiative.

Monoaryloxide pyrrolide (MAP) imido alkylidene complexes of molybdenum and tungsten that contain 2,6-bis(2,5-R2-pyrrolyl) phenoxide (R = i-Pr, Ph) ligands and an unsubstituted metallacyclobutane on its way to losing ethylene

description: We report the synthesis of Mo and W MAP complexes that contain O-2,6-(2,5-R2-pyrrolyl)2C6H3 (2,6-dipyrrolylphenoxide or ODPPR) ligands in which R = i-Pr, Ph. W(NAr)(CH-t-Bu)(Pyr)(ODPPPh) (4a; Ar = 2,6-disopropylphenyl, Pyr = pyrrolide) reacts readily with ethylene to yield a metallacyclobutane complex, W(NAr)(C3H6)(Pyr)(ODPPPh) (5). The structure of 5 in the solid state shows that it is approximately a square pyramid with the WC4 ring spanning apical and basal positions. This SP′ structure, which has never been observed as an actual intermediate, must now be regarded as an integral feature of the metathesis reaction. © 2013 American Chemical Society.

description: Measurement of the absolute value of the applied pressure in high-pressure muon and neutron experiments is a complicated task. It requires both the presence of a calibration material inside the sample volume as well as additional time for refining the response of the calibrant. Here we describe the use of optical calibrants for precise determination of the pressure value inside the piston-cylinder clamp cells. Utilizing the concept of separate volumes for the sample and the optical media, a new setup for conducting in-situ pressure measurements has been successfully tested. Pressures in both the `sample' and the `optical' volumes were proved to be the same within experimental accuracy. The use of SrB$_{4}$O$_7$:(0.01 Sm$^{2+}$, 0.03 Eu$^{2+}$) as a pressure calibrant allows for a high accuracy of pressure determination by considering up to eight fluorescence lines.

Learning to acquire novel cognitive tasks with evolution, plasticity and meta-meta-learning

description: A hallmark of intelligence is the ability to autonomously learn new flexible, cognitive behaviors - that is, behaviors where the appropriate action depends not just on immediate stimuli (as in simple reflexive stimulus-response associations), but on contextual information that must be adequately acquired, stored and processed. While many meta-learning algorithms can design agents that autonomously learn new tasks, cognitive tasks adds another level of learning and memory to typical ``learning-to-learn'' problems. Here we evolve neural networks, endowed with plastic connections and neuromodulation, over a sizable set of simple cognitive tasks adapted from a computational neuroscience framework. The resulting evolved networks can automatically modify their own connectivity to acquire a novel simple cognitive task, never seen during evolution, from stimuli and rewards alone, through the spontaneous operation of their evolved neural organization and plasticity system. Our results emphasize the importance of carefully considering the multiple learning loops involved in the emergence of intelligent behavior.
Driven Disordered Polymorphic Solids: Phases and Phase Transitions, Dynamical Coexistence and Peak Effect Anomalies

description: We study a model for the depinning and driven steady state phases of a solid tuned across a polymorphic phase transition between ground states of triangular and square symmetry. These include pinned states which may have dominantly triangular or square correlations, a plastically flowing liquid-like phase, a moving phase with hexatic correlations, flowing triangular and square states and a dynamic coexistence regime characterized by the complex interconversion of locally square and triangular regions. We locate these phases in a dynamical phase diagram. We demonstrate that the apparent power-law orientational correlations we obtain in our moving hexatic phase arise from circularly averaging an orientational correlation function with qualitatively different behaviour in the longitudinal (drive) and transverse directions. The intermediate coexistence regime exhibits several novel properties, including substantial enhancement in the current noise, an unusual power-law spectrum of current fluctuations and striking metastability effects. This noise arises from the fluctuations of the interface separating locally square and triangular ordered regions. We demonstrate the breakdown of effective ``shaking temperature'' treatments in the coexistence regime by showing that such shaking temperatures are non-monotonic functions of the drive in this regime. Finally we discuss the relevance of these simulations to the anomalous behaviour seen in the peak effect regime of vortex lines in the disordered mixed phase of type-II superconductors. We propose that this anomalous behavior is directly linked to the behavior exhibited in our simulations in the dynamical coexistence regime, thus suggesting a possible solution to the problem of the origin of peak effect anomalies.
