description: The orbit and fundamental physical parameters of the double-lined eclipsing binary V505 Per are derived by means of Echelle high resolution, high S/N spectroscopy and B, V photometry. Effective temperatures, gravities, rotational velocities and metallicities are obtained from atmospheric chi^2 analysis. An E(B-V)<=0.01 mag reddening is derived from interstellar NaI and KI lines. The distance to the system computed from orbital parameters (60.6 +/- 1 pc) is identical to the newly re-reduced Hipparcos parallax (61.5 +/- 1.9 pc). The masses of the two components (M(1) = 1.2693 +/- 0.0011 and M(2) = 1.2514 +/- 0.0012 Msun) place them in the transition region between convective and radiative stellar cores of the HR diagram, with the more massive of the two showing already the effect of evolution within the Main Sequence band (T(1) = 6512 +/- 21 K, T(2) = 6462 +/- 12 K, R(1) = 1.287 +/- 0.014, R(2) = 1.266 +/- 0.013 Rsun). This makes this system of particular relevance to theoretical stellar models, as a test on the overshooting. We compare the firm observational results for V505 Per component stars with the predictions of various libraries of theoretical stellar models (BaSTI, Padova, Granada, Yonsei-Yale, Victoria-Regina) as well as BaSTI models computed specifically for the masses and chemical abundances of V505 Per. We found that the overshooting at the masses of V505 Per component stars is already pretty low, but not null, and described by efficiencies lambda(OV)=0.093 and 0.087 for the 1.27 and 1.25 Msun components, respectively. According to the computed BaSTI models, the age of the system is about 0.9 Gyr and the element diffusion during this time has reduced the surface metallicity from the initial [M/H]=-0.03 to the current [M/H]=-0.13, in excellent agreement with observed [M/H]=-0.12 +/- 0.03.

The role of the disk magnetization on the hysteresis behavior of X-ray binaries

description: We present a framework for understanding the dynamical and spectral properties of X-ray Binaries, where the presence of an organized large scale magnetic field plays a major role. Such a field is threading the whole accretion disk with an amplitude measured by the disk magnetization $μ(r,t) =B_z^2/(μ_o P_{tot})$, where $P_{tot}$ is the total, gas and radiation, pressure. Below a transition radius $r_J$, a jet emitting disk (the JED) is settled and drives self-collimated non relativistic jets. Beyond $r_J$, no jet is produced despite the presence of the magnetic field and a standard accretion disc (the SAD) is established. The radial distribution of the disk magnetization $μ$ adjusts itself to any change of the disk accretion rate $\dot m$, thereby modifying the transition radius $r_J$. We propose that a SAD-to-JED transition occurs locally, at a given radius, in a SAD when $μ=μ_{max} \simeq 1$ while the reverse transition occurs in a JED only when $μ=μ_{min}\simeq 0.1$. This bimodal behavior of the accretion disk provides a promising way to explain the hysteresis cycles followed by X-ray binaries during outbursts.

description: This paper presents GPFC, a novel Graphics Processing Unit (GPU) Phase Folding and Convolutional Neural Network (CNN) system to detect exoplanets using the transit method. We devise a fast folding algorithm parallelized on a GPU to amplify low signal-to-noise ratio transit signals, allowing a search at high precision and speed. A CNN trained on two million synthetic light curves reports a score indicating the likelihood of a planetary signal at each period. While the GPFC method has broad applicability across period ranges, this research specifically focuses on detecting ultra-short-period planets with orbital periods less than one day. GPFC improves on speed by three orders of magnitude over the predominant Box-fitting Least Squares (BLS) method. Our simulation results show GPFC achieves $97%$ training accuracy, higher true positive rate at the same false positive rate of detection, and higher precision at the same recall rate when compared to BLS. GPFC recovers $100\%$ of known ultra-short-period planets in $\textit{Kepler}$ light curves from a blind search. These results highlight the promise of GPFC as an alternative approach to the traditional BLS algorithm for finding new transiting exoplanets in data taken with $\textit{Kepler}$ and other space transit missions such as K2, TESS and future PLATO and Earth 2.0.

description: We propose a geometric phase gate of two ion qubits that are encoded in two levels linked by an optical dipole-forbidden transition. Compared to hyperfine geometric phase gates mediated by electric dipole transitions, the gate has many interesting properties, such as very low spontaneous emission rates, applicability to magnetic field insensitive states, and use of a co-propagating laser beam geometry. We estimate that current technology allows for infidelities of around 10$^{-4}$.

Publisher: name: Zenodo
Year: 2022

description: The goal of this deliverable is to present the second version of the Workflow User Interface (UI) for Project Managers, intended to be used off-site by relevant stakeholders to support them on day-to-day activities. Such a UI should provide up-to-date information about the construction progress, including a detailed overview of the work orders and tasks status, and related KPIs. Through the UI, the Project Managers should have a clear view and understanding of the construction works progress, allowing decisions and optimalisation of project plans. Hence, they should have access to an overview of the actual construction works progress against the planned schedule.

The abovementioned requirements and additional ones that were elicited and documented in “D2.1-Stakeholder requirements for the COGITO system” have been considered to develop and deliver the second version the Workflow UI for Project Managers, which mainly constitutes the off-site frontend solution for the Adaptive Workflow Management and Automation tool, named hereafter Work Order Definition and Management tool (WODM). Therefore, this deliverable should be read in conjunction with the deliverable “D6.6-Adaptive Workflow Management and Automation Tool v2”, where the current status of the WODM backend has been described.
Metacognition and Language Learning: Creating Effective K–12 Learners
Creators: name: Hernberg, Stacey
Publisher: name: BC TEAL Journal
Year: 2020

description: In British Columbia’s K–12 schools, five years of funded English Language Learning support is frequently not enough to help English language learners fully develop their English language proficiency. This critical analysis examines the literature on metacognition and language learning to find practical metacognitive instructional features to equip students who are learning English as an additional language with the awareness and the strategies they need to effectively further develop their academic language. By analyzing and synthesizing the literature, it is clear that several models of metacognition have been developed. Yet, there is still a need for a fuller model to be developed, thus helping educators better understand how metacognitive instruction can be implemented. Furthermore, little research can be found on metacognitive instruction with K–12 language learners. Therefore, theme analysis for effective features of metacognitive instruction with post-secondary language learners was used to uncover the most useful characteristics which might prove promising for K–12 students in British Columbia. The result is the identification of four features of effective metacognitive instruction that could be used in conjunction with a proposed fuller model of metacognition in language learning.

description: Motivated by recent experiments showing nonlinear elasticity of in vitro networks of the biopolymer actin cross-linked with filamin, we present an effective medium theory of flexibly cross-linked stiff polymer networks. We model such networks by randomly oriented elastic rods connected by flexible connectors to a surrounding elastic continuum, which self-consistently represents the behavior of the rest of the network. This model yields a crossover from a linear elastic regime to a highly nonlinear elastic regime that stiffens in a way quantitatively consistent with experiment.

description: We report on a recent multi-band optical photometric and polarimetric observational campaign of the blazar OJ 287 which was carried out during September 2016 -- December 2017. We employed nine telescopes in Bulgaria, China, Georgia, Japan, Serbia, Spain and the United States. We collected over 1800 photometric image frames in BVRI bands and over 100 polarimetric measurements over ~175 nights. In 11 nights with many quasi-simultaneous multi-band (V, R, I) observations, we did not detect any genuine intraday variability in flux or color. On longer timescales, multiple flaring events were seen. Large changes in color with respect to time and in a color--magnitude diagram were seen, and while only a weak systematic variability trend was noticed in color with respect to time, the color--magnitude diagram shows a bluer-when-brighter trend. Large changes in the degree of polarization, and substantial swings in the polarization angle were detected. The fractional Stokes parameters of the polarization showed a systematic trend with time in the beginning of these observations, followed by chaotic changes and then an apparently systematic variation at the end. These polarization changes coincide with the detection and duration of the source at very high energies as seen by VERITAS. The spectral index shows a systematic variation with time and V-band magnitude. We briefly discuss possible physical mechanisms that could explain the observed flux, color, polarization, and spectral variability.

description: The response of superconducting aluminum to electromagnetic radiation is investigated in a broad frequency (45 MHz to 40 GHz) and temperature range ($T>T_c/2$), by measuring the complex conductivity. While the imaginary part probes the superfluid density (Cooper-pairs), the real part monitors the opening of the superconducting energy gap and -- most important here -- the zero-frequency quasi-particle response. Varying the mean free path gives some insight into the dynamics, scattering and coherence effects of the quasi-particles in the superconducting state.

English-as-an-Additional-Language Employees’ Perspectives on Writing in the Workplace

Publisher: name: BC TEAL Journal
Year: 2020

description: This article presents study results on workplace writing from English-as-an-additional-language (EAL) employees’ perspectives, and shares findings about how educational institutions in British Columbia can better prepare EAL students to write in the workplace. In post-secondary academic writing, content rather than writing accuracy is often emphasized, yet most employers consider writing accuracy important as it reflects a company’s image (Hu & Hoare, 2017), and how EAL employees perceive their writing preparedness, workplace writing accuracy, and language challenges remains unexplored. Thus, we inquired: 1) How do EAL employees graduated from English-speaking universities and working in English-medium environments perceive workplace writing accuracy? 2) To what extent are they prepared for workplace writing? 3) What writing challenges do they encounter? 4) What do they think universities can do to better prepare EAL students for workplace writing? The study employed qualitative interviews with nine EAL employees who graduated from British Columbia universities and were working at English-medium companies in Canada. Data analysis suggests that the participants highly valued writing accuracy; however, their education did not prepare them adequately. In addition, the participants suggested that universities offer more communication, business, and professional writing courses; enhance support services; invite employers and EAL employees as guest speakers; and incorporate real-life scenarios in the curriculum.

description: To help people find code that they might want to reuse, repositories of end-user code typically sort scripts by number of downloads, ratings, or other information based on prior uses of the code. However, this information is unavailable when code is new or when it has not yet been reused. Addressing this problem requires identifying reusable code based solely on information that exists when a script is created. To provide such a model for web macro scripts, we identified script traits that might plausibly predict reuse, then used IBM CoScripter repository logs to statistically test how well each corresponded to actual reuse. These tests confirmed that the traits generally did correspond to higher levels of reuse as anticipated. We then developed a machine learning model that uses these traits as features to predict reuse of macros. Evaluating this model on repository logs showed that its accuracy is comparable to that of existing machine learning models for predicting reuse—but with a much simpler structure. Sensitivity analysis revealed that our model is quite robust; its quality is greatly reduced only when parameters are set to such extreme values that the model becomes inordinately selective. Testing the model with individual traits revealed those that provided the best predictions on their own. Based on these results, we outline opportunities for using our model to improve repositories of end-user code.

Spinning Mellin Bootstrap: Conformal Partial Waves, Crossing Kernels and Applications

Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study conformal partial waves (CPWs) in Mellin space with totally symmetric external operators of arbitrary integer spin. The exchanged spin is arbitrary, and includes mixed symmetry and (partially)-conserved representations. In a basis of CPWs recently introduced in arXiv:1702.08619, we find a remarkable factorisation of the external spin dependence in their Mellin representation. This property allows a relatively straightforward study of inversion formulae to extract OPE data from the Mellin representation of spinning 4pt correlators and in particular, to extract closed-form expressions for crossing kernels of spinning CPWs in terms of the hypergeometric function ${}_4F_3$. We consider numerous examples involving both arbitrary internal and external spins, and for both leading and sub-leading twist operators. As an application, working in general $d$ we extract new results for ${\cal O}\left(1/N\right)$ anomalous dimensions of double-trace operators induced by double-trace deformations constructed from single-trace operators of generic twist and integer spin. In particular, we extract the anomalous dimensions of double-trace operators $[\mathcal{O}_JΦ]_{n,l}$ with ${\cal O}_J$ a single-trace operator of integer spin $J$.

An Insider View: Understanding Volunteers’ Experiences Within a Peer-to-Peer Language Learning Program in Vancouver’s Downtown Eastside
Creators: name: Balyasnikova, Natalia
Publisher: name: BC TEAL Journal
Year: 2020

description: Many community-based English language learning programs rely on volunteers to lead classes. While some of these volunteers have some teacher training, the majority are not professional educators. The question of how non-professionals understand what constitutes facilitation of language learning in an adult education context remains underexplored. This paper presents the findings of a small-scale study conducted within a community-based language learning program with four volunteer facilitators. Volunteer facilitators were interviewed on a range of topics related to their role in the program, peer-to-peer interaction, and the impacts of volunteering in their lives. An analysis of facilitator interviews, with reference to program’s guiding educational principles, reveals the following positive factors related to the program: the informal nature of the community, the flexible design of the program, peer-to-peer interaction, and support from program staff. However, the findings also highlight that facilitators’ perspectives and practices varied significantly due to their different lived experiences, motives for volunteering, and linguistic background. This study highlights promising practices, which could serve to design sustainable community-based English language learning programs for adults.

description: We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the Cygnus-X star forming region. One of the objects, BD+43 3710, has a bipolar nebula, possibly due to an outflow or a torus of material. A second, HBHA 4202-22, a Wolf-Rayet candidate, shows a circular shell of 24 micron emission suggestive of either a limb-brightened shell or disk seen face-on. No diffuse emission was detected around either of these two objects in the Spitzer 3.6-8 micron Infrared Array Camera (IRAC) bands. The third object is the luminous blue variable candidate G79.29+0.46. We resolved the previously known inner ring in all four IRAC bands. The 24 micron emission from the inner ring extends ~1.2 arcmin beyond the shorter wavelength emission, well beyond what can be attributed to the difference in resolutions between MIPS and IRAC. Additionally, we have discovered an outer ring of 24 micron emission, possibly due to an earlier episode of mass loss. For the two shell stars, we present the results of radiative transfer models, constraining the stellar and dust shell parameters. The shells are composed of amorphous carbon grains, plus polycyclic aromatic hydrocarbons in the case of G79.29+0.46. Both G79.29+0.46 and HBHA 4202-22 lie behind the main Cygnus-X cloud. Although G79.29+0.46 may simply be on the far side of the cloud, HBHA 4202-22 is unrelated to the Cygnus-X star formation region.
The Quest for Standardization: The Canadian Federal Government and the Language Instruction for Newcomers to Canada (LINC) Program
Creators: name: Mudzingwa, Calisto
Publisher: name: BC TEAL Journal
Year: 2020

description: Since the inception of the Language Instruction for Newcomers to Canada (LINC) Program in 1992, the Canadian federal government, through the ministry responsible for immigration, has diligently sought to bring consistency to the program through a variety of government initiatives. These include operational bulletins, curriculum guidelines, standardized placement assessments, in-class assessment procedures and protocols, standards for describing and measuring the language proficiency of adult immigrants speaking English as an additional language (EAL), and a variety of other guidelines (e.g., waitlist management). This paper introduces a novel LINC standardization model as a tool for describing and analyzing how the synergies of these government initiatives converge to bring consistency to the entire LINC Program. The model comprises four stages: a Pre-Entry Stage, Entry Stage, Language Training Stage, and Exit Stage. These stages represent phases an adult LINC learner goes through on their LINC English language learning journey. The model highlights the centrality of the Canadian Language Benchmarks (CLBs) by showing how they are the mainstay of most, if not all, of the other government initiatives. Both positive and negative implications for the government’s quest for standardization are discussed.

description: ABSTRACT

Background: Healthcare-associated infections (HCAIs), infections acquired while receiving medical care, pose a significant risk to patients and remain a major cause of morbidity and mortality worldwide. Investigating the causative agents and their antimicrobial susceptibility profiles is essential to optimize the management and reduce the rate of these infections. However, there is a critical research gap in low-income settings, including Ethiopia. Therefore, this study aims to assess the prevalence, antimicrobial resistance patterns, and factors associated with HCAIs at MCM Comprehensive Specialized Hospital in Ethiopia.

Methods: A retrospective chart review study was conducted among 414 patients admitted between January 1st and December 31st, 2022. Data were abstracted using a pre-tested, structured electronic questionnaire, which was then exported to SPSS V.20.0 software for analysis. Data were summarized using frequencies and percentages. To identify factors associated with the development of HCAIs, a binary logistic regression model was fitted at 5% level of significance. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were used to interpret significant results.

Results: The prevalence of healthcare-associated infections (HCAIs) was 13% (54/414), with the most common infections being urinary tract infections (21/54) and hospital-acquired pneumonia (17/54). Among the 54 HCAI cases, bacterial pathogens were detected and cultured in 34 patients. The most frequently identified bacteria were Coagulase-Negative Staphylococcus (9/34), Escherichia coli (8/34), and Enterococcus species (7/34). Antibiotic susceptibility testing revealed complete resistance to Ceftriaxone in 25/34 isolates and resistance to Cotrimoxazole in 33/34 isolates. Length of hospital stay exceeding 7 days, use of a urinary catheter, history of chronic respiratory disease, and previous antibiotic use were identified as significant factors associated with HCAI development.

Conclusions: The prevalence of HCAIs was high at MCMCSH. The common bacterial pathogens isolated exhibited high resistance to commonly prescribed antimicrobials. The findings highlight the importance of emphasizing early detection and management of infections, particularly in vulnerable patient populations, implementing comprehensive infection prevention protocols, reducing unnecessary hospital stays, rational antibiotic use with an antibiogram-guided therapy approach, and prioritizing targeted catheterization practices.

description: End-user programming tools offer no data types except “string ” for many categories of data, such as person names and street addresses. Consequently, these tools cannot automatically validate or reformat these data. To address this problem, we have developed a userextensible model for string-like data. Each “tope ” in this model is a user-defined abstraction that guides the interpretation of strings as a particular kind of data. Specifically, each tope implementation contains software functions for recognizing and reformatting instances of that tope’s kind of data. This makes it possible at runtime to distinguish between invalid data, valid data, and questionable data that could be valid or invalid. Once identified, questionable and/or invalid data can be double-checked and possibly corrected, thereby increasing the overall reliability of the data. Valid data can be automatically reformatted to any of the formats appropriate for that kind of data. To show the general applicability of topes, we describe new features that topes have enabled us to provide in four tools.

description: We examine a simple scheme to generate genuine multipartite entangled states across disjoint qubit registers. We employ a shuttle qubit that is sequentially coupled, in an energy preserving manner, to the constituents within each register through rounds of interactions. We establish that stable $W$-type entanglement can be generated among all qubits within the registers. Furthermore, we find that the entanglement is sensitive to how the shuttle is treated, showing that a significantly larger degree is achieved by performing projective measurements on it. Finally, we assess the resilience of this entanglement generation protocol to several types of noise and imperfections, showing that it is remarkably robust.

description: Current universe (assumed here to be normal matter on the brane) is pressureless from observations. In this case the energy condition is $ρ_0\geq0$ and $p_0=0$. By using this condition, brane models can be distinguished. Then, assuming arbitrary component of matter in DGP model, we use four known energy conditions to study the matter on the brane. If there is nonnormal matter or energy (for example dark energy with $w

Worth the Risk: Towards Decentring Whiteness in English Language Teaching
Creators: name: Gerald, JPB
Publisher: name: BC TEAL Journal
Year: 2020

description: The field of English language teaching (ELT) has long centred whiteness without acknowledging as much. Practitioners accept the field’s racial disparities under the guise of the search for profit, yet hegemonic whiteness controls our institutions, our curricula, and our pedagogy unless we, as members of this field, consciously seek to counteract its influence. White ELT professionals are incentivized to maintain the racial status quo and many exhibit fierce resistance when efforts are made to discuss white supremacy in English teaching. In this article, I demonstrate how ELT frames whiteness as both a prize and a goal, explain the deleterious impact whiteness has on racialized students and teachers, argue for the necessity of decentring whiteness, and provide suggestions for ways we can push our field towards a future where whiteness no longer reigns supreme.

description: Suppose we have many copies of an unknown $n$-qubit state $ρ$. We measure some copies of $ρ$ using a known two-outcome measurement $E_{1}$, then other copies using a measurement $E_{2}$, and so on. At each stage $t$, we generate a current hypothesis $σ_{t}$ about the state $ρ$, using the outcomes of the previous measurements. We show that it is possible to do this in a way that guarantees that $|\operatorname{Tr}(E_{i} σ_{t}) - \operatorname{Tr}(E_{i}ρ) |$, the error in our prediction for the next measurement, is at least $\varepsilon$ at most $\operatorname{O}\!\left(n / \varepsilon^2 \right) $ times. Even in the "non-realizable" setting---where there could be arbitrary noise in the measurement outcomes---we show how to output hypothesis states that do significantly worse than the best possible states at most $\operatorname{O}\!\left(\sqrt {Tn}\right) $ times on the first $T$ measurements. These results generalize a 2007 theorem by Aaronson on the PAC-learnability of quantum states, to the online and regret-minimization settings. We give three different ways to prove our results---using convex optimization, quantum postselection, and sequential fat-shattering dimension---which have different advantages in terms of parameters and portability.

Are Academic English Words Learned Incidentally? A Canadian Case Study
Creators: name: Freimuth, Hilda
Publisher: name: BC TEAL Journal
Year: 2020

description: This study at a Canadian university grew out of the need to know whether students acquired academic vocabulary incidentally through text exposure (extensive reading) in class. The ability to explicitly teach all the words on the academic word list is an unreasonable expectation for a one-semester course. This study, therefore, investigated whether thirteen English as an additional language (EAL) students in a capstone foundation course (academic reading and writing) acquired vocabulary simply through exposure to a variety of different academic texts (such as policy papers, essays, journal articles, and book chapters) in class. Students assessed their own vocabulary knowledge and development through Paribakht and Weschke’s (1993) Vocabulary Knowledge Scale (VKS) at the beginning of the study (Week 3) and again at the end of the semester (Week 13). Results indicated a vocabulary gain for almost all students, even with word exposure frequencies as low as one to four. Further research on incidental academic vocabulary acquisition is needed using other instrumentation to confirm the findings.

description: This research presents a new turbulence generation method based on stochastic wavelets and tests its various properties in both homogeneous and inhomogeneous turbulence. Turbulence field can be generated with less basis compared to previous synthetic Fourier methods. Adaptive generation of inhomogeneous turbulence is achieved by scale reduction algorithm and lead to smaller computation cost.

Moving Beyond Individual Peer Review Tasks: A Collaborative Written Corrective Feedback Framework
Creators: name: Maatouk, Zeina

Publisher: name: BC TEAL Journal
Year: 2020

description: English as an additional language (EAL) teachers include peer feedback activities during the writing process to foster autonomy amongst EAL writers and support target language development. Research has demonstrated the importance of providing peer feedback training to learners in order to improve the efficacy of peer revision (Rahimi, 2013). Peer feedback review activities, however, are often individual tasks despite the evidence that collaborative writing activities are essential for EAL learners (Wigglesworth & Storch, 2012). This classroom practice article introduces a threefold pedagogical training designed for English for academic purposes (EAP) learners which combines individual and collaborative peer review activities. The proposed peer collaborative written corrective feedback framework (C-WCF) scaffolds novice academic writers through the peer review process while emphasizing collaborative learning.

The t copula with Multiple Parameters of Degrees of Freedom: Bivariate Characteristics and Application to Risk Management

description: The t copula is often used in risk management as it allows for modelling tail dependence between risks and it is simple to simulate and calibrate. However, the use of a standard t copula is often criticized due to its restriction of having a single parameter for the degrees of freedom (dof) that may limit its capability to model the tail dependence structure in a multivariate case. To overcome this problem, grouped t copula was proposed recently, where risks are grouped a priori in such a way that each group has a standard t copula with its specific dof parameter. In this paper we propose the use of a grouped t copula, where each group consists of one risk factor only, so that a priori grouping is not required. The copula characteristics in the bivariate case are studied. We explain simulation and calibration procedures, including a simulation study on finite sample properties of the maximum likelihood estimators and Kendall's tau approximation. This new copula can be significantly different from the standard t copula in terms of risk measures such as tail dependence, value at risk and expected shortfall. Keywords: grouped t copula, tail dependence, risk management.

description: We develop a method for accurately calculating vacuum decay rates beyond the thin-wall regime in a pure scalar field theory at the one-loop level of the effective action. It accounts for radiative effects resulting from quantum corrections to the classical bounce, including gradient effects stemming from the inhomogeneity of the bounce background. To achieve this, it is necessary to compute not only the functional determinant of the fluctuation operator in the background of the classical bounce but also its functional derivative evaluated at the classical bounce. The former is efficiently calculated using the Gel'fand-Yaglom method. We illustrate how the latter can also be calculated with the same method, combined with a computation of various Green's functions.

description: El nogal es, junto al cerezo, una de las especies forestales más prometedoras y de valor que pueden proporcionar más de 3000 euros por árbol a agricultores tras varias décadas de crecimiento (30 años en Galicia). Sin embargo, las grandes inversiones iniciales asociadas a la plantación junto con los costes de mantenimiento asociados a operaciones selvícolas como la poda y la clara limitan que los agricultores los planten, ya que no se obtienen otros productos a partir de la zona plantada hasta la primera clara comercial o la cosecha. Por otra parte, las zonas arables desarboladas producen cultivos pero también descapitalizan la fertilidad del suelo lo que puede ser resuelto a través de la introducción de plantaciones con espaciamiento amplio de nogal. Los nogales son especialmente adecuados para el crecimiento de cultivo de invierno incluyendo los cereales ya que estos brotan tarde en primavera lo que permite al cultivo recibir mucha luz incluso en plantaciones densas. También se debe realizar una poda alta que permite disminuir la competencia entre el árbol y el cultivo. La selección de la variedad de nogal debe asegurar la mejor forma de los troncos para producir madera de calidad. La selección de variedades tempranas de cultivos debe realizarse para su establecimiento bajo el arbolado. El proyecto español AFCLIMA tiene por objeto evaluar el desarrollo de diferentes variedades de centeno, trigo, maíz, triticale y cebada bajo nogal de diferentes edades establecidos en diferentes zonas de España.
Eikonal zeros in the momentum transfer space from proton-proton scattering: An empirical analysis

description: By means of improved empirical fits to the differential cross section data on $pp$ elastic scattering at $19.4 \le\sqrt{s}\le 62.5$ GeV and making use of a semi-analytical method, we determine the eikonal in the momentum transfer space (the inverse scattering problem). This method allows the propagation of the uncertainties from the fit parameters up to the extracted eikonal, providing statistical evidence that the imaginary part of the eikonal (real part of the opacity function) presents a zero (change of signal) in the momentum space, at $q^2 \approx 7 \pm 1$ GeV$^2$. We discuss the implication of this change of signal in the phenomenological context, showing that eikonal models with one zero provide good descriptions of the differential cross sections in the full momentum transfer range, but that is not the case for models without zero. Empirical connections between the extracted eikonal and results from a recent global analysis on the proton electric form factor are also discussed, in special the Wu-Yang conjecture. In addition, we present a critical review on the $pp$ differential cross section data presently available at high energies.

description: The Software Engineering Institute’s Capability Maturity Model for software (CMM) has had a major influence on software process and quality improvement. Although the CMM has been widely adopted, there remain many misunderstandings about how to use it effectively for business-driven software process improvement, particularly for small organizations and small projects. This article discusses how to use the CMM correctly and effectively in any business environment, with examples for small organizations, rapid prototyping projects, maintenance shops, R&D outfits, and others. The conclusion is that the issues associated with interpreting the software CMM are essentially the same for any organization interested in improving its software processes—the differences are of degree rather than kind. Using the software CMM effectively and correctly requires professional judgment and an understanding of how the CMM is structured to be used for different purposes.
