description: In hidden sector models with an extra U(1) gauge group, new fields can interact with the Standard Model only through gauge kinetic mixing and the Higgs portal. After the U(1) is spontaneously broken, these interactions couple the resultant cosmic strings to Standard Model particles. We calculate the spectrum of radiation emitted by these "dark strings" in the form of Higgs bosons, Z bosons, and Standard Model fermions assuming that string tension is above the TeV scale. We also calculate the scattering cross sections of Standard Model fermions on dark strings due to the Aharonov-Bohm interaction. These radiation and scattering calculations will be applied in a subsequent paper to study the cosmological evolution and observational signatures of dark strings.

Most businesses around the world have started using e-commerce. When using the e-commerce platform, it becomes easier to gather data about the users of the platform. Businesses must utilize this data collected to the best of their ability. This would result in the growth and survival of the businesses. In this project, we are going to discuss some reasons why businesses would want to invest in predicting the future using machine learning, learn the process of data mining, and identify and discuss a few different type of classifiers which can be used in prediction. To demonstrate how machine learning and different classifiers work, a dataset is acquired from the internet and analysis was performed on it. Using the analysis, a conclusion on the state of the website was prepared. The improvements the business could make to generate more revenue were identified and stated. Classifiers were used on the dataset after it was split 70-30 (train and test respectively) to check the performance of the classifiers.

description: Background: It is particularly difficult to choose the appropriate prosthesis to treat infective endocarditis. Objectives: To investigate the outcomes after aortic valve replacement with a stented bioprosthesis (Trifecta) in patients with active or previous infective endocarditis. Methods: We performed a single-centre, retrospective study including consecutive patients with infective endocarditis who underwent aortic valve replacement between July 2011 and June 2019. Survival and reintervention were assessed as of December 2021. Hospital mortality was defined as death in-hospital or within 30-days of surgery. Kaplan-Meier method was used for time-to-event outcome assessment (all-cause mortality and reoperation). Data are median (minimum and maximum) or absolute (relative) frequencies. Results: We included 51 patients, median age of 69 (40 to 87) years, 78% male. The median follow-up time was 5.4 years and the maximum was 10 years. Most patients (71%) had native valve infective endocarditis and 16% had previous endocarditis. Surgery was urgent in 82%. Hospital mortality occurred in 10 patients (20%). After excluding these patients, 1-, 3-, 6-, and 9-years cumulative survival rates were 93%, 78%, 72%, and 72%, respectively. There were five bioprosthesis-related reoperations: 4 due to endocarditis at 1-year, 3-years, and 5-years on follow-up (n=1, 1 and 2, respectively) and 1 due to non-structural deterioration, 6-years after surgery. Conclusions: Despite the small sample size, this report supports a satisfactory performance profile of the Trifecta bioprosthesis in the treatment of infective endocarditis.

description: For the integrable system on $e(3,2)$ found by Sokolov and Tsiganov we obtain explicit equations of some invariant 4-dimensional manifolds on which the induced systems are almost everywhere Hamiltonian with two degrees of freedom. These subsystems generalize the famous Appelrot classes of critical motions of the Kowalevski top. For each subsystem we point out a commutative pair of independent integrals, describe the sets of degeneration of the induced symplectic structure. With the help of the obtained invariant relations, for each subsystem we calculate the outer type of its points considered as critical points of the initial system with three degrees of freedom.

description: We present a Herschel far-IR and sub-mm study of a sample of 120 galaxies in 28 Hickson Compact Groups. Fitting their UV to sub-mm spectral energy distributions with the model of da Cunha et al. (2008), we accurately estimate the dust masses, luminosities and temperatures of the individual galaxies. We find that nearly half of the late-type galaxies in dynamically "old" groups, those with more than 25% of early-type members and redder UV-optical colours, have also significantly lower dust-to-stellar mass ratios compared to those of actively star-forming galaxies of the same mass found both in HCGs and the field. Examining their dust-to-gas mass ratios we conclude that dust was stripped out of these systems as a result of the gravitational and hydrodynamic interactions, experienced due to previous encounters with other group members. About 40% of the early-type galaxies (mostly lenticulars), in dynamically "old" groups, display dust properties similar to those of the UV-optical red late-type galaxies. Given their stellar masses, star formation rates and UV-optical colours, we suggest that red late-type and dusty lenticular galaxies represent transition populations between blue star-forming disk galaxies and quiescent early-type ellipticals. [...ABRIDGED...] Our deep Herschel observations also allow us to detect the presence of diffuse cold intragroup dust in 4 HCGs. We also find that the fraction of 250micron emission which is located outside of the main bodies of the red late-type galaxies as well as of the dusty lenticulars is 15-20% of their integrated emission at this band. All these findings are consistent with an evolutionary scenario in which gas dissipation, shocks and turbulence in addition to tidal interactions, shape the evolution of galaxies in compact groups.

Coded Distributed Diversity: A Novel Distributed Reception Technique for Wireless Communication Systems

Subjects: subject: Information Theory (cs.IT)

description: In this paper, we consider a distributed reception scenario where a transmitter broadcasts a signal to multiple geographically separated receive nodes over fading channels, and each node forwards a few bits representing a processed version of the received signal to a fusion center. The fusion center then tries to decode the transmitted signal based on the forwarded information from the receive nodes and possible channel state information. We show that there is a strong connection between the problem of minimizing a symbol error probability at the fusion center in distributed reception and channel coding in coding theory. This connection allows us to design a unified framework for coded distributed diversity reception. We focus linear block codes such as simplex codes or first-order Reed-Muller codes that achieve the Griesmer bound with equality to maximize the diversity gain. Due to its simple structure, no complex offline optimization process is needed to design the coding structure at the receive nodes for the proposed coded diversity technique. The proposed technique can support a wide array of distributed reception scenarios, i.e., arbitrary $M$-ary symbol transmission at the transmitter and received signal processing with multiple bits at the receive nodes. Numerical studies show that the proposed coded diversity technique can achieve practical symbol error rates even with moderate signal-to-noise ratio and numbers of the receive nodes.

description: Networks of autonomous vehicles roaming in smart cities raise new challenges for end-to-end protection of data in terms of integrity, privacy, efficiency, and scalability. This paper provides a survey of Networks of Trusted Execution Environments (NTEE) architectures. NTEE combine the strong, hardware-rooted security guarantees of the TEE deployed locally in the vehicle, with the distributed protection of a decentralized consensus protocol. We identify three main families of consensus protocols and analyze their architectures, performance, and security, including improvements brought by the TEE. Overall, voting protocols tend to be more efficient for smaller networks, while lottery-based schemes are not easy to apply in a vehicular context due to higher overheads. Both types of protocols reach an intermediate level of security, with variations in byzantine tolerance and types of threats. Graph based protocols tend to achieve both efficiency and flexibility in terms of network topology support, but their security still remains to be explored.

description: A 16-year-old female, without relevant previous medical history, presented with 1 year episodic and progressive hemoptysis. CT scan revealed an abnormal blood supply from the descending thoracic aorta to the left lower lobe, the later presenting with significant signs of hyperperfusion. Therapy consisted of ligation of the anomalous vessel followed by left lower lobe lobectomy. Lung sequestration is a rare congenital pulmonary malformation, mostly diagnosed in childhood. The typical symptoms are recurrent pulmonary infections or productive cough and only in rare situations severe hemoptysis occurs. Preoperative planning with CT or MR angiography is important to identify the aberrant blood supply. The treatment of choice is surgical ligation of the feeding vessel in combination with lung resection.

description: We present the first results of an ALMA spectral survey of strong absorption lines for common interstellar species in the z=0.89 molecular absorber toward the lensed blazar PKS1830-211. The dataset brings essential information on the structure and composition of the absorbing gas in the foreground galaxy. In particular, we find absorption over large velocity intervals (gtrsim 100 km/s) toward both lensed images of the blazar. This suggests either that the galaxy inclination is intermediate and that we sample velocity gradients or streaming motions in the disk plane, that the molecular gas has a large vertical distribution or extraplanar components, or that the absorber is not a simple spiral galaxy but might be a merger system. The number of detected species is now reaching a total of 42 different species plus 14 different rare isotopologues toward the SW image, and 14 species toward the NE line-of-sight. The abundances of CH, H2O, HCO+, HCN, and NH3 relative to H2 are found to be comparable to those in the Galactic diffuse medium. Of all the lines detected so far toward PKS1830-211, the ground-state line of ortho-water has the deepest absorption. We argue that ground-state lines of water have the best potential for detecting diffuse molecular gas in absorption at high redshift.

description: Narrative experiences are characterized by dynamic emotional responses. Research has begun to investigate implications of emotional shifts for narrative processing, but the continuous measurement of emotion poses a challenge. This study examines how valence shifts captured using real-time response (RTR) measurement during two films relate to transportation and post-exposure self-reported emotional flow. Across both films, valence shifts (in terms of the mean intra-individual standard deviation of RTR valence) were positively correlated with transportation and self-reported emotional flow. Valence shifts and self-reported emotional flow were higher among women than men. We discuss the use of RTR measurement for the assessment of emotional shifts during narrative processes.

description: Introduction: Cardiovocal or Ortner’s syndrome is a rare cause of vocal cord paralysis. Damage to the left recurrent laryngeal nerve may be caused by an aortic arch aneurysm, in even rarer cases. Clinical case: A 60-year-old woman presented with hoarseness lasting for six months. Paralysis of the left vocal cord was confirmed with laryngoscopy and an aortic arch aneurysm was diagnosed on chest CT. Despite correction of the aortic aneurysm, her hoarseness did not improve. Discussion: Mediastinal disease may cause vocal cord paralysis, due to the intrathoracic course of the recurrent laryngeal nerve. The assessment of the superior mediastinum on CT is mandatory in these cases. In cardiovocal syndrome, cardiovascular diseases damage the recurrent laryngeal nerve. Aortic aneurysms are a rare cause of Ortner’s, especially when they affect the distal portion of the aortic arch and stretch the left recurrent laryngeal nerve at the aortopulmonary window.

description: Sponsoring is an important external communication tool, where organisations spend more than 60 billion US dollars annually pre pandemic with a strong growth rate predicted for the years ahead. In particular, sport sponsorship represents the vast majority of this communication expenditure. Leveraging the full potential of (sport) sponsorship, its strategy needs to extend beyond external communications to include internal branding and to appeal to employees as a second audience. Successful internal branding means consistently fulfilling the brand promise, differentiating from competitors, and providing a competitive advantage. However, the value of leveraging sport sponsorship to appeal to both internal and external audiences is rarely documented and research in this area remains scarce. Therefore, because of this gap in this area and the value that research can add to organisations, this research explores how sport sponsorship can contribute to internal branding to propose a more effective way of leveraging sport sponsorship for internal branding. This research study in the context of internal branding links back to resource-based view theory, where human resources are seen as the decisive factor for differentiating and achieving a competitive advantage.

An inductive, qualitative research design explores how sport sponsorship can contribute to internal branding. Considering the interrelatedness of internal branding and employer branding, part of this research explores how sport sponsoring can also assist with employer branding. This research differentiates itself from existing sponsoring-related internal branding research by applying a cross-disciplinary research design across 10 countries and four continents, including marketing, human resources, internal branding, employer branding, and sponsoring lenses alike. This strategy proved successful as rich data emerged from the online focus groups.

The main contribution of this research represents a novel conceptual model that enables a holistic brand knowledge management approach to optimise leveraging internal branding and employer branding potential from sport sponsorship. This model informs how to disseminate and foster sponsoring and branding knowledge throughout the organisation. This model can also be used when evaluating which sponsoring partnership to select whilst ensuring that the partnership will provide maximum contribution to the brand.
A narrative inquiry into the experiences of two educators who provide learning support in Alberta K-9 public school contexts
Creators: Hendrickson, Jacob
Publisher: name: University of Alberta Library
Year: 2022

This research explores the experiences of two Learning Support Teachers (LST’s) supporting students with learning needs in Alberta k-9 public schools. Guided by narrative inquiry methodology, this research seeks to illuminate tools, strategies, methods, and practices utilized by LST participants that have, in their experience, been effective in furthering the educational experience of students with learning needs and have supported colleagues. Through rich discussion, reflection, and inquiry, each participant brought to the research unique understandings. Narrative analysis transcripts of research discussion alongside participants revealed six resonant threads, including: wearing multiple hats, leadership role, the use of documentation, relationships with parents, team approach, and partnership with counselling. This research can provide current educators and stakeholders supporting students with learning needs insights and possible implications for their practice.

description: Background: The objectives of our study are to evaluate our surgical experience of mediastinal bronchogenic cyst (MBC) and to determine the results of resection by video-assisted thoracic surgery (VATS) and posterolateral thoracotomy (PLT). Methods: The demographic characteristics, clinical and radiological features intraoperative data, outcomes and fol- low-up information were reviewed and analyzed from 38 patients who underwent resection of a MBC between 2008 and 2019. Results: cystectomy was performed for thirty eight patients included in the present study. Seventeen of them, benefited from VATS cystectomy (VATS group) with 1 conversion to thoracotomy (5.9%) and 21 underwent PLT cystectomy (PLT group). In our series 27 (71.1%) were male. Their average age was 42.6 years. While 09 patients (23.7%) had no symptoms pre-operatively, 29 patients (76.3%) were symptomatic. There were no operative deaths and 3 patients (7.9%) presented postoperative complications. The average duration of hospital stay was 3.2 days for patients who had VATS, but 5.8 days for those who had thoracotomy. Long-term follow-up (range, 1 to 8 years) showed no late complications and no recurrence. Conclusion: VATS and PLT are main approaches for the surgical resection of MBCs VATS is a safe procedure, with less pain and time spent at the hospital. Early surgical procedures of MBCs may be recommended to prevent complications. Surgical adhesions are unfavorable conditions to thoracoscopic treatment.

description: The correlated band theory implemented as a combination of the local density approximation with the exact diagonalization of the Anderson impurity model is applied to PuO$_2$. We obtain an insulating electronic structure consistent with the experimental photoemission spectra. The calculations yield the band gap of 1.8 eV and a non-magnetic singlet ground state that is characterized by a non-integer filling of the plutonium $f$ shell ($n_f\approx 4.5$). Due to sizeable hybridization of the $f$ shell with the $p$ states of oxygen, the ground state is more complex than the four-electron Russell--Saunders ${}^5{\rm I}_4$ manifold split by the crystal field. The inclusion of hybridization improves the agreement between the theory and experiment for the magnetic susceptibility.

Unfortunately, this research quickly stalled after we struggled to reproduce performance results and predictive models shared by volunteers across rapidly changing systems. In this talk, I will describe my 10-year effort to solve numerous reproducibility issues in ML&systems research. I will share my experience reproducing 150+ systems and ML papers during artifact evaluation at ASPLOS, MLSys, CGO, PPoPP and Supercomputing. This tedious experience motivated me to develop the Collective Knowledge framework and the open cKnowledge.io portal to bring DevOps principles to our research. I will also present cKnowledge solutions - a new way to package and share research artifacts and results with common Python APIs, CLI actions, portable workflows and JSON meta descriptions. Such solutions can be used to automatically build, benchmark and validate ML&system experiments across continuously evolving platforms. I will conclude with several practical use-cases of our technology in collaboration with Arm, IBM, General Motors, the Raspberry Pi foundation and MLPerf. Our long-term goal is to help researchers share their new ML techniques as production-ready packages along with published papers and participate in collaborative and reproducible benchmarking, co-design and comparison of efficient ML/software/hardware stacks.

description: We report the first extragalactic detection of chloronium (H2Cl+), in the z=0.89 absorber in front of the lensed blazar PKS1830-211. The ion is detected through its 1_11-0_00 line along two independent lines of sight toward the North-East and South-West images of the blazar. The relative abundance of H2Cl+ is significantly higher (by a factor ~7) in the NE line of sight, which has a lower H2/H fraction, indicating that H2Cl+ preferably traces the diffuse gas component. From the ratio of the H2^35Cl+ and H2^37Cl+ absorptions toward the SW image, we measure a 35Cl/37Cl isotopic ratio of 3.1 (-0.2; +0.3) at z=0.89, similar to that observed in the Galaxy and the solar system.

Implementing distributed leadership within elementary schools
Creators: Prystupa, Kyla Christie
Publisher: name: University of Alberta Library
Year: 2022

Effective school leadership is important for the overall success of a school and its members. The distributed leadership model is an approach that some school leadership teams have used to build capacity in members of the school community, foster a sense of community, and create better teaching and learning environments for all. This research investigates how formal school leadership teams implement distributed leadership, and the impact that distributed leadership has on school climate in two Urban Catholic Elementary schools. I begin by providing an understanding of distributed leadership based on review of the literature. Next, I present interview data from the school administrators regarding their definition of distributed leadership, the approach they take to implementing this model of leadership, and the perceived impacts it has on members of the school community. Finally, I draw connections between my research data and the literature that highlight the importance of communication, building meaningful relationships that foster a sense of trust, and using the strengths of staff members to successfully implement distributed leadership within the school.

description: The general aim of the study was to determine the impact of legal regulations in force on the market of liquid biofuels and biocomponents in Poland on the prices of fatty acid methyl esters (so-called biodiesel or BIO100 biofuel). Therefore, we indicated the importance of legal regulations in shaping biodiesel prices in Poland based on empirical data from the period of 2008-2016 (the latest available data). An additional purpose was to assess the legal regulations as drivers of ecodiesel (diesel with an admixture of biodiesel) prices in Poland based on empirical data from the period 2004-2021. Institutional, legal and economic variables were distinguished, assuming that the biofuel market, like many other markets, is so heavily regulated that taking legal acts into consideration is crucial for its functioning. Multiple regression analysis was used. The sources of data were officially available databases (PKN Orlen Data, FRED Economic Research Data, as well as USD/PLN exchange rate quotations), while the sources of legal acts were the Journal of Laws of the Republic of Poland and the Official Journal of the European Union. The obtained results indicated that the prices of biofuels (specifically biodiesel) in Poland depend both on economic factors (the USD/PLN exchange rate and crude oil prices) and on some legal regulations, including domestic and EU regulations. We proved the importance of the EU directive 2003/30 on the promotion of the use of biofuels or other renewable fuels for transport, as well as acts on renewable energy sources (2015), on amending the act on liquid biocomponents and biofuels (2014) and on excise duty (2008).

description: Investigating the evolution of protoplanetary disks is crucial for our understanding of star and planet formation. Several theoretical and observational studies have been performed in the last decades to advance this knowledge. FT Tauri is a young star in the Taurus star forming region that was included in a number of spectroscopic and photometric surveys. We investigate the properties of the star, the circumstellar disk, and the accretion and ejection processes and propose a consistent gas and dust model also as a reference for future observational studies. We performed a multi-wavelength data analysis to derive the basic stellar and disk properties, as well as mass accretion/outflow rate from TNG-Dolores, WHT-Liris, NOT-Notcam, Keck-Nirspec, and Herschel-Pacs spectra. From the literature, we compiled a complete Spectral Energy Distribution. We then performed detailed disk modeling using the MCFOST and ProDiMo codes. Multi-wavelengths spectroscopic and photometric measurements were compared with the reddened predictions of the codes in order to constrain the disk properties. This object can serve as a benchmark for primordial disks with significant mass accretion rate, high gas content and typical size.

description: The implantation of the left ventricular assist device Abbott HeartMate 3TM is being increasingly performed for management of end-stage heart failure. LVAD implantation might be associated with early or late right ventricular dysfunction. When severe, a temporary right ventricular support device may need to be implanted. However, these situations are associated with higher mortality. We report a successful case of temporary right ventricular support following HeartMate 3 implantation.

description: The electronic functionality of thin films is governed by their interfaces. This is very important for the ferroelectric (FE) state which depends on thin-film clamping and interfacial charge transfer. Here we show that in a heterostructure consisting of a nano-granular metal and an organic FE layer of [tetrathiafulvalene]$^{+δ}$[p-chloranil]$^{-δ}$ the nano-granular layer's conductance provides a sensitive and non-invasive probe of the temperature-dependent dielectric properties of the FE layer. We provide a theoretical framework that is able to qualitatively reproduce the observed conductance changes taking the anisotropy of the dielectric anomaly at the paraelectric(PE)-FE phase transition into account. The approach is also suitable for observing dynamical effects close to the phase transition. Focused electron beam induced deposition as fabrication method for the nano-granular metal guarantees excellent down-scaling capabilities, so that monitoring the FE state on the lateral scale down to 20--30\,nm can be envisioned.

description: 84-year-old male, with a history of firearm incident with accidental gunshot shooting, and multiple projectile injuries, 40 years prior. No advanced medical treatment was required at the time. A CT was recently performed for unrelated reasons, and the scout view shows multiple projectiles, a total of 50, scattered in the thoracoabdominopelvic region as well as the lower limbs. CT angiography exposed CT’s scout view of the multiple projectiles scattered. an arteriovenous fistula in posterior branches of the hypogastric artery with moderate dilations of the superior gluteal vein. The patient was completely asymptomatic and had no findings suggestive of AVF-related cardiac failure. Physical examination was unremarkable. Conservative treatment without further imagiological follow-up was decided, if patient continued asymptomatic.

description: Objectives: Surgery provides the best chance for cure in patients with non-small-cell lung cancer stage I or II, but only a small portion of all new cases diagnosed are eventually suitable for surgical resection. Our goal was to appraise the surgical outcomes including survival and progression rates in patientswith histological diagnosis of lung cancer. Methods: Between 1st August 2012 and 30th June 2018, the patients with histological lung cancer diagnosis that underwent surgical resection with a curative intent at the department of Cardiothoracic Surgery of Centro Hospitalar Univer- sitário de São João were included. Results: The majority of patients were pathological stage I and the most performed surgery was a lobectomy (90.6%). The hospitality mortality was 1,3% and the rate of complication was 26,1%. Patients with forced expiratory volume in 1 second (FEV1) less than 80% had higher (statistically significant difference) frequency of complications. Active smokers, Eastern Co- operative Oncology Group Performance Status (ECOG PS)value different than 0 and FEV1 inferior to 80% had a higher mean length of drainage and higher mean length of stay (statistically significant difference). The overall survival was 92,6% at 1 year, 87,7 % in 2 years and 79,1% in 5 years. The overall survival according to pathological stages were similar when compared with the literature. Conclusions: Ours results are similar to international centers and we should be more alert to preoperative assessment.

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: In this paper we consider integrable dispersive chains associated with the so called Energy Dependent Schrodinger operator. In a general case multi component reductions of these dispersive chains are new integrable systems, which are characterised by two arbitrary natural numbers. Also we show that integrable three dimensional linearly degenerate quasilinear equations of a second order possess infinitely many differential constraints. Corresponding dispersive reductions are integrable systems associated with the Energy Dependent Schrodinger operator.

description: Locating the gamma-ray emission sites in blazar jets is a long-standing and highly controversial issue. We investigate jointly several constraints on the distance scale r and Lorentz factor Gamma of the gamma-ray emitting regions in luminous blazars (primarily flat spectrum radio quasars, FSRQs). Working in the framework of one-zone external radiation Comptonization (ERC) models, we perform a parameter space study for several representative cases of actual gamma-ray flares in their multiwavelength context. We find a particularly useful combination of three constraints: from an upper limit on the collimation parameter Gamma*theta ~ 0.1 - 0.7. Typical values of r corresponding to moderate values of Gamma ~ 20 are in the range 0.1 - 1 pc, and are determined primarily by the observed variability time scale t_var,obs. Alternative scenarios motivated by the observed gamma-ray/mm connection, in which gamma-ray flares of t_var,obs ~ a few days are located at r ~ 10 pc, are in conflict with both the SSC and cooling constraints. Moreover, we use a simple light travel time argument to point out that the gamma-ray/mm connection does not provide a significant constraint on the location of gamma-ray flares. We argue that spine-sheath models of the jet structure do not offer a plausible alternative to external radiation fields at large distances, however, an extended broad-line region is an idea worth exploring.

Architectural Alphabets
Ronzani Editore

description: “L’architecture commença comme toute écriture. Elle fut d’abord alphabet” (“Architecture begins like all writing. It is first an alphabet”) – proclaimed Victor Hugo in 1832. This updated edition of Sergio Polano’s essay illuminates one of the less visible aspects of this claim, the primer called the “abbecedario” or ABC book. The notion of an architectonics of the alphabet at first appears exotic, but corresponds with the making of alphabets in curious, sometimes bizarre forms since early print culture. The essay is accompanied by a rich and fascinating repertoire of examples of architectural alphabets. Sergio Polano, abbecedari architettonici, Ronzani 2022.
