A Wave Diffraction Problem with Higher Order Impedance Boundary Conditions

In this paper, we consider an impedance boundary transmission problem for the Helmholtz equation originated by a problem of wave diffraction by an infinite strip with higher order imperfect boundary conditions. Operator theoretical methods and relations between operators are built to deal with the problem and, as consequence, a transparent interpretation of the problem in an operator theory framework are associated to the problem. In particular, different types of operator relations are exhibited for different types of operators acting between Lebesgue and Sobolev spaces on a finite interval and the positive half-line. All this has consequences in the understanding of the structure of this type of problems. At the end, we describe when the operators associated with the problem enjoy the Fredholm property in terms of the initial space order parameters.
SmartCiteCon: Implicit Citation Context Extraction from Academic Literature Using Supervised Learning

We introduce SmartCiteCon (SCC), a Java API for extracting both explicit and implicit citation context from academic literature in English. The tool is built on a Support Vector Machine (SVM) model trained on a set of 7,058 manually annotated citation context sentences, curated from 34,000 papers from the ACL Anthology. The model with 19 features achieves F1=85.6%. SCC supports PDF, XML, and JSON files out-of-box, provided that they are conformed to certain schemas. The API supports single document processing and batch processing in parallel. It takes about 12–45 seconds on average depending on the format to process a document on a dedicated server with 6 multithreaded cores. Using SCC, we extracted 11.8 million citation context sentences from ~33.3k PMC papers in the CORD-19 dataset, released on June 13, 2020. We will provide continuous supplementary data contribution to the CORD-19 and other datasets. The source code is released at https://gitee.com/irlab/SmartCiteCon.
A study on efficacy of ambroxol in the treatment of acute bronchitis in tertiary care hospital

Background: Upper respiratory tract infections (URTI), including acute bronchitis, are the frequent health problems and the most common reason for acute cough in adults. Even though the infections are caused mainly by viruses, and their course is usually not complicated, febrifuges, i.a. mucokinetics, or antitussives are used in the treatment of URTI in order to improve the quality of life and safety of patients. Methods: The present study was prospective and observational study. Data from adult patients treated with ambroxol hydrochloride for acute bronchitis were collected and compared with data from patients treated for the same condition without ambroxol preparations. The severity of bronchitis symptoms was evaluated with the respiratory rate, retraction score, wheezing score and oxygen saturation (SPO2) between visits patients conducted self-observations and filled out observation diaries. Baseline clinical symptomatolgy of breathlessness, cough, and sputum severity scoring were compared before and after 3 and 7 days of treatment in both groups. Results: Majority of the patient’s infections were cured. Most of patients considered the studied drugs to be the agent decreasing the duration of infection and its intensity. The percentage of patients who declared that they had a less intense cough than during earlier infections was higher in the group of patients treated with ambroxol treated patients. Patients treated with Ambroxol hydrochloride to be very safe. Conclusions: Ambroxol is an efficient, well-tolerated, and safe drug. Its efficacy in the treatment of acute bronchitis symptoms in adult patients is similar to the efficacy of other preparations.
Myosorex cafer – Dark-footed Forest Shrew

Taxonomic notes: Meester et al. (1986) recognised the subspecies M. c. cafer and M. c. sclateri but biochemical and morphological data suggested a rise to full species status for both (Maddalena & Bronner 1992; Kearney 1993). Isolated populations in the highlands of Zimbabwe and Mozambique; and north-eastern Limpopo have been previously assigned to M. cafer (Friedmann & Daly 2004). Within the M. cafer complex, Willows-Munro (2008) and Taylor et al. (2013), using a combination of molecular and morphological characters, demonstrated considerable lineage diversification. Myosorex sclateri and M. cafer were split in 2008 (Willows-Munro 2008). The Zimbabwe Although once considered to occur in Limpopo Province, Zimbabwe and Mozambique, recent morphological and genetic evidence indicates that M. cafer is endemic to the KwaZulu-Natal and Eastern Cape provinces of South Africa (WillowsMunro 2008; Taylor et al. 2013).

Epistemic uncertainty of plane-stress continuum concrete models

This article deals with the epistemic uncertainty of plane-stress finite element (FE) models. It is well known that the nonlinear response of reinforced concrete structures is strongly dependent on the stress-strain constitutive concrete models adopted. Herein, this uncertainty is evaluated using five different continuum constitutive concrete models, which are very popular in FE software. Because several of these models fail to converge in strain-softening regimes, modified models are proposed for their consistent plane-stress numerical implementation. The five concrete models studied are: (i) the hyperbolic Drucker-Prager (DPH) plastic model; (ii) the Lubliner-Lee-Fenves (LLF) plastic-damage model; (iii) the Wu-Li-Faría (WLF) model; (iv) the Faría-OliverCervera (FOC) model; and (v) the total strain rotating (ROT) smeared-crack model. All models have been implemented in ANSYS software using user-material FORTRAN routines, which are adequate for shell-type finite elements. Results were validated using a set of experimental benchmark tests subjected to uniaxial and biaxial stress states under monotonic and cyclic loadings. Epistemic uncertainty in the model responses are qualitatively described and quantified as well.
Clinical and epidemiological characteristics and morphological peculiarities of urogenital trichomoniasis nowadays

Importance of the topic is stipulated with the current significant spread of infectious diseases of the urogenital tract, caused by the representatives of the protozoa genus Trichomonas . Aim. Evaluate the prevalence and peculiarities of contemporary trichomonas infection ( Trichomonas vaginalis, Pentatrichomonas hominis, Trichomonas tenax ), with the consideration of the associated bacterial infections that cause the urogenital pathology and the ultrastructural peculiarities of Trichomonas vaginalis morphotypes in the patients with chronic infectious diseases of the genitourinary organs. Material and methods. The research was carried out among 377 patients with chronic infectious diseases of the genitourinary organs. Routine bacterioscopic and bacteriological methods were applied. In addition, Trichomonas tenax and Pentatrichomonas hominis were detected using real-time polymerase chain reaction and applying original experimental primers. The ultrastructure of the trichomonads was studied using a PEM-125K electron microscope equipped with the SAI-01A (SELMI) system, using a CCD camera DX 2 and KAPPA software package. Results. Trichomonas vaginalis was detected in 48.3 % using the methods of optical microscopy and culture media inoculation. Trichomonas tenax was detected in 18.2 % and Pentatrichomonas hominis was detected in 67.1 % with the polymerase chain reaction. Development of the pathological process in the urogenital system of the studied patients (up to 90 %) was caused with the microbial associations, in particular, with Ureaplasma urealyticum (26.1 %), Chlamydia trachomatis (16.7 %), Mycoplasma hominis and Mycoplasma genitalium (13.9 %) and various kinds of opportunistic pathogenic microflora (up to 60 %), which lead to dysbiosis of urogenital system. It was proved that the oval morphotype Trichomonas vaginalis may be referred to the virulent forms; it was detected more often (68 %) than the piriform morphotype. Conclusions. Possible presence of trichomonads of three species: Trichomonas vaginalis, Trichomonas tenax, Pentatrichomonas hominis , in particular in pathological microbial associations, as important factors of the emergence and / or development of the pathological process, was established in the human genitourinary system. It is reasonable to refer the oval morphotype Trichomonas vaginalis to the virulent forms of this agent.
Potential Longevity of Maize Seeds under Storage in Humid Tropical Seed Stores

This study was undertaken to calibrate open seed warehouse storage environments in the humid tropics and model maize seed deterioration under them. Five maize varieties (TZPBSR, DMR-ESR-Y, Oba Super-2, Suwan-1-SRY, and ART-98-SW1) were used for the study. The seeds were cleaned and their initial quality determined by recommended methods. One kilogramme of seeds of the five maize varieties were packaged in separate moisture-proof polythene bags (with automatic thermohygrometers inserted to monitor changes in temperature and RH) and placed in the seed stores at the University of Agriculture, Abeokuta (UNAAB) and the Institute of Agricultural Research and Training, Ibadan (IAR&T) from 2005-2007. Seed samples were taken at 3month interval and evaluated for seed viability and seedling vigour attributes. Probit analysis was used to estimate seed deterioration and potential longevity. PROC GLM statement of SAS was used to separate means of variables evaluated in both environments. The seed survival curves under the humid tropical conditions fitted the normal distribution curve well (p {χ}>0.05); with UNAAB seed storage environment extending the longevity of stored seeds far better than the IAR&T seed store. Overall, results showed that effective seed storage under humid tropical conditions is possible, though effectiveness may differ from one environment to the other. [Oyekale, K. O. ; Daniel, I.

Techniques for Efficient Automated Elimination of False Positives

Static analysis tools are useful to detect common programming errors. However, they generate a large number of false positives. Postprocessing of these alarms using a model checker has been proposed to automatically eliminate false positives from them. To scale up the automated false positives elimination (AFPE), several techniques, e.g., program slicing, are used. However, these techniques increase the time taken by AFPE, and the increased time is a major concern during application of AFPE to alarms generated on large systems.To reduce the time taken by AFPE, we propose two techniques. The techniques achieve the reduction by identifying and skipping redundant calls to the slicer and model checker. The first technique is based on our observation that, (a) combination of application-level slicing, verification with incremental context, and the context-level slicing helps to eliminate more false positives; (b) however, doing so can result in redundant calls to the slicer. In this technique, we use data dependencies to compute these redundant calls. The second technique is based on our observation that (a) code partitioning is commonly used by static analysis tools to analyze very large systems, and (b) applying AFPE to alarms generated on partitioned-code can result in repeated calls to both the slicer and model checker. We use memoization to identify the repeated calls and skip them.The first technique is currently under evaluation. Our initial evaluation of the second technique indicates that it reduces AFPE time by up to 56%, with median reduction of 12.15%.
Identifying landslides from continuous seismic surface waves: a case study of multiple small-scale landslides triggered by Typhoon Talas, 2011

Landslides can cause devastating damage. In particular, heavy rainfall-triggered landslides pose a chain of natural hazards. However, such events are often difficult to detect, leaving the physical processes poorly understood. Here we apply a novel surface-wave detector to detect and locate landslides during the transit of Typhoon Talas 2011. We identify multiple landslides triggered by Typhoon Talas, including a landslide in the Tenryu Ward, Shizuoka prefecture, Japan, $\sim 400\, {\rm km}$ east from the typhoon track. The Tenryu landslide displaced a total volume of $1.2\! -\! 1.5 \times 10^{6}\, {\rm m}^3$ . The landslide is much smaller than those detected by using globally recorded surface waves, yet the event generated coherent seismic signals propagating up to 3000 km away. Our observations show that attributes of small and large landslides may follow the same empirical scaling relationships, indicating possible invariant failure mechanisms. Our results also suggest an alerting technology to detect and locate landslides with a sparse seismic network.
GEOLOGY AND GEOCHRONOLOGY OF THE ISLAND LAKE GREENSTONE BELT, NORTHWESTERN SUPERIOR PROVINCE

The Island Lake greenstone belt is composed of volcanic and volcanogenic sedimentary rocks of the Hayes River Group and sedimentary rocks of the Island Lake Group, all of which are intruded by various plutons. Field mapping and geochronological work in 2001 demonstrated that 1) the Hayes River Group in the western portion of the belt can be divided into lithologically and chronologically distinct structural panels that are correlated with those previously defined in the eastern portion of the belt; 2) there exists a distinct ca. 2728 Ma volcanic unit in the belt; and 3) the Island Lake Group is unconformable on the Bella Lake pluton. The mapping also led to a better definition of the location and nature of the Savage Island Shear Zone in the western part of the belt and the kinematics of the Chapin Bay Shear Zone in the area.
The Political Economics of Non-Democracy

We survey recent theoretical and empirical literature on political economics of non-democracies. Dictators face many challenges to their rule: internal, such as palace coups or breakdown of their support coalition, or external, such as mass protests or revolutions. We analyze strategic decisions made by dictators — hiring political loyalists to positions that require competence, restricting media freedom at the cost of sacrificing bureaucratic efficiency, running a propaganda campaign, organizing electoral fraud, purging associates and opponents, and repressing citizens — as driven by the desire to maximize the regime's chances of staying in power. We argue that the key to understanding the functioning and ultimately the fate of a nondemocratic regime is the information flows within the regime, and the institutions that govern these information flows.
Analysis of Secant Algorithm for Optimal Path Length of Point-To-Point Microwave Link

In this study, Secant algorithm was developed for computing the optimal path length of a point-to-point microwave. Also, the impact of various parameters on the convergence of the algorithm is also presented. Mathlab program was developed and used to carry out sample numerical computations of optimal path length and other performance parameters for a given microwave link. The results showed that convergence cycle of 5 is achieved for a microwave link operating at the frequency of 12 GHz and in rain zone N, with percentage availability of 99.99% . Also, the results showed that the secant algorithm , as presented in this study is suitable for the occasion when rain fading dominates. In that case, the convergence cycle of the secant algorithm is quite stable, maintaining values between 5 and 6 even in the face of variations in frequency, percentage availability and rain rate. In any case, the secant method can still be improved to yield low convergence cycle in the face of multipath fading. Furthermore, the iterative secant method may not be needed when the multipath fading dominate since it is possible to develop close form mathematical solution to determine the optimal path length when the multipath fading

A New Species of the Colubrid Snake Genus Geophis from Colombia

A new species of the colubrid genus Geophis is described from the Cordillera Occidental, Departamento del Valle del Cauca, Colombia. This new species is most similar to members of the championi group. It is diagnosed from this group and all other species in Central and South America by the presence of two postocular scales. It is easily distinguished from all other species of Geophis by combinations of features of scalation and by color pattern. This new species occurs sympatrically with the only other species known from South America, G. nigroalbus of the sieboldi group. In the course of herpetofaunal investi- gations in the Departamento del Valle, Co- lombia, numerous specimens of two species of Geophis have been collected. One of these is an undescribed species that differs mark- edly from the more common and sympatric Geophis nigroalbus as well as from all other species in the genus. We describe this dis- tinct taxon as:

Strategic Management of HRM Practices and Innovation Performance in the High Tech Fiberglass Sector in Bahrain: Mediating Role of Organizational Innovation

Growing use of fiberglass admixture in construction along with automotive industries has escalated demand of fiberglass among the firms and fueling them with the innovational strategy in order to be competitive. Fiberglass businesses being one of the high-tech sectors have to consider many domains. Although, due to the inflexibility of employees, the absence of innovative atmosphere and monopolistic composition, employees are unwilling to be innovative in organizations. The current study argued that strategic management of new HRM practices through enhancing more skillful, talented, committed, motivated can further innovation and innovational employees that helps in higher productivity of the organization. However, to demonstrate this connection is insufficient in terms of empirical evidence. Consequently, the main objective of this investigation to examine role of strategic management of New HRM practices on innovation performance followed by the mediation of organizational innovation. Data has collected from Bahrain’s manufacturing sector of fiberglass that came up with significant positive association between the endogenous and exogenous variables.
ON FLUID FLOW AROUND TRASH-RACKS

Trash-racks provide protection for hydraulic turbines by blocking entrance of large debris that could damage turbine parts. Trash-racks also help reduce fish injuries and mortality caused with fish entrapment in turbine. Installation of trash-racks is necessary, but causes inevitable head losses that decrease water turbine energy production. With increasing ecological concerns different bar-rack configurations are examined to provide better fish protection, mostly not considering head losses. Experimental results of head losses caused by trash-racks found in literature are conducted on scaled models due to experiment facility limitations while number of investigated configurations is limited with cost of production. Most head loss equations derived from experimental results are valid only in specific range of parameters. Considering these limitations, numerical simulations would enable investigation of a large number of trash-rack combinations, where simulations can be conducted for turbine intake geometries made in full scale. In this work numerical simulation results will be compared with experimental results from literature. Geometry, mesh and simulation parameters will be investigated, considering influence on simulation results agreement with experiment. Guidelines for numerical simulation setup will be provided for future work where investigation of trash-rack configurations that are not yet covered in literature can be conducted.
