Numrug Strictly Protected Area (SPA) is aunique part of Mongolia’s protected areas system.Located in Dornod Aimag at the easternmost edgeof Mongolia, bordering China, it is considered tobe part of the Eastern Steppe region. However,Nomrog SPA is quite different from the rest of theEastern Steppe in topography, soils, vegetation, andwildlife. Nomrog SPA is the southern- and western-most reach of the Great Khinghan Mountains (mostof this range occurs in China), and it is also theonly part of this mountain range that receivesProtected Area status. Nomrog is one of the fewplaces in Mongolia where one can find Manchurianmoose (Alces alces cameloides) (Jia et al. 1994),and it is also suspected of harboring brown bear(Ursus arctos), lynx (Felis lynx), otter (Lutra lutra)and other Palearctic species normally associatedwith the northern taiga of Siberia. The area alsohas an unusual mix of Manchurian species,including a variety of birds such as the reedparrotbill (Paradoxornis heudei) and Mandarinduck (Aix galericulata), some of which reach theirwestern limits here and are found nowhere else inMongolia (Shardarsuren 1997)
Characteristics of successful puma kill sites of elk in the Black Hills, South Dakota

Published: January 2017

Elk Cervus canadensis nelsoni in the Black Hills, South Dakota, have been declining since 2006 and there is concern by resource managers and hunters that puma Puma concolor predation may be contributing to declining herds. We evaluated characteristics at sites where puma successfully killed elk in the Black Hills of South Dakota. We evaluated characteristics at coarse (79‐ha plots) and fine (0.2‐ha plot) scales across the landscape. Our primary objective was to obtain a better understanding of vegetation and terrain characteristics that may have facilitated greater susceptibility of elk to predation by puma. We evaluated effects of road density, terrain heterogeneity, probability of elk use, and vegetation variables at 62 puma kill sites of elk and 186 random sites to identify key landscape attributes where elk were killed by puma. Elk were killed by puma in high use areas. Elk were also killed in areas that had greater amounts of edge and intermediate ruggedness at the coarse scale. Further, elk were killed in areas with greater small tree density and woody debris at the fine scale. High germination rates of ponderosa pine trees are unique to the Black Hills and provide dense patches of cover for puma. We hypothesize that cover from small trees and woody debris provided conditions where puma could stalk elk in areas with optimal security cover for elk. We suggest managers implement vegetation management practices that reduce small tree density and woody debris in areas with greater density of meadow—forest edge if they are interested in potentially diminishing hiding cover for puma in elk high use areas.
Being John McEnroe

Using the 2011 Toronto Nuit Blanche re-enactment of the infamous Borg–McEnroe tiebreaker at the 1980 Wimbledon final and a McEnroe exhibition match in Hamilton as critical touchstones, this article investigates the intersections between sports psychology and acting theory, the powers of commerce to produce particular performances of self, and the racial politics of anger.
A Pedagogical Trip to the Field of Dreams
Authors: Knowles Ric
Published: January 2017

“A Pedagogical Trip to the Field of Dreams” describes and rationalizes taking an Introduction to Theatre class to a baseball game as the first event of the course. It finds connections between sports and theatre around issues of space and time, play, performativity, ritual, recreation, and representation that move entry-level students’ attention from the page to the stage, beyond the questions of language, character, and plot that many have learned in secondary school to ask of dramatic literature.
The Rules of (Dis)Engagement: Exploiting the Formal Characteristics and Reception Etiquette of Team Sports in Binge Culture’s Break Up [We Need to Talk]
Authors: McKinnon James
Published: January 2017

How do the pleasures of the theatre spectator compare with those of the sports fan? In Break Up (We Need to Talk), an improvised durational performance that creates and disintegrates a romantic relationship before our eyes, Binge Culture Collective adopts some of the fundamental conventions of games and sports to generate the unpredictability and excitement that characterizes high-stakes sporting events. The performers, like athletes, follow a set of rules that create tension between collaboration and competition, and create a framework which endows significance upon the actions that take place within it. As in sports, the rules, though unspoken, are overt – there is no attempt to hide them beneath a veneer of realism. Rather, we are invited to enjoy the vicarious thrills of performers struggling with and against each other – and against the clock, which demands that they take six hours to build up to the final action suggested by the title. As the rules gradually cause the performers succumb to the physical and mental exhaustion, the level of uncertainty and unpredictability rises – as does the audience’s excitement.
Preparing Oregon for Connected Vehicle Deployment: Application Prioritization Process
Authors: Bertini Robert L. , Wang Haizhong , Carstens Kevin
Published: January 2017

To build on a project recently completed for the Oregon Department of Transportation (DOT), processes and tools were developed to prioritize the implementation of connected vehicle (CV) applications. Internal mechanisms for addressing CV development and deployment at the Oregon DOT were assessed; the technical maturity of each potential CV application was scanned, reviewed, and assessed; preliminary goals were developed; prospective CV applications were linked; and applications that fit with the potential role of the Oregon DOT in advancing these initiatives were refined, prioritized, and ranked. A shared vision and business plan that prioritizes CV applications for Oregon is recommended. An internal effort aimed at producing a small set of priority CV applications for further development is described. This effort culminated in a CV application prioritization workshop that included a priority mapping exercise, discussion of the CV concept, and an initial mapping of goals and applications. The workshop identified seven near-term priority CV applications for the Oregon DOT; 12 applications that the Oregon DOT will monitor (and possibly collaborate on with others in the future); and eight applications that the Oregon DOT will monitor but that will be led by others. The Oregon DOT has used the results of this effort as a springboard for hiring new staff dedicated to CV policy, forming a CV steering team, and launching a CV business plan. The process and tools can be used by other states and transportation agencies in their CV application prioritization processes.

Published: January 2017

Background:

New prognostic factors such as IgVh mutational status, ZAP-70 protein expression and cytogenetic abnormalities have shown to offer important prognostic information for patients with chronic lymphocytic leukemia (CLL). Our aim was to evaluate the optimal cut-off for IgVh mutational status, ZAP-70 expression and cytogenetic abnormalities in association with disease progression defined as the need for treatment within 3 years from diagnosis in 170 patients with B-CLL.

Design and methods:

Receiver operating characteristics (ROC) analysis and multivariate general linear models (GLMs) were used to investigate the most significant cut-off values of these biomarkers and their prognostic impact.

Results:

Our findings estimated that the optimal cut-off for IgVh mutation status and for ZAP-70 protein expression was 97% and 16.5% respectively and a high concordance between the two was demonstrated. We identified 30% as being the best-cut-off for 17p-, 11q- and 6q-. In univariate analysis 17p- was found to be a significant predictor of the event only for the whole population. Multivariate analysis including all biological parameters, identified 11q deletion as the only significant regressor.

Conclusions:

We assessed that IgVh mutational status, ZAP-70 protein and 6q- are powerful prognostic markers. Analyses of all these factors revealed that 11q deletion was the strongest predictor of disease progression in B-CLL.
Prognostic significance of serum Her2/neu, BCL2, CA15-3 and CEA in breast cancer patients: A short follow-up
Authors: Samy Nervana , Ragab Halla M. , El Maksoud Nabila Abd , Shaalan Mohamed
Published: January 2017

Breast cancer is the most common malignancy in women, options for treatment of breast cancers are complex and varied, there is a need for biological prognostic indicators that would, alone or in combination with others, be sufficient to predict disease recurrence and hence, the basis for supplemental treatment after local therapy.

The aim of this study was to determine prognostic significance of serum Her2/neu, BCL2, CA 15-3 and CEA during the follow-up of the patients with breast cancer, also, to investigate the association between these biomarkers and clinicopathological parameters and patient outcomes in breast cancer.

Patients and methods: Eighty nine patients with breast cancer stage I and II are enrolled in our study. Their age ranged from 35–59 years. Patients underwent radical mastectomy or breast-conserving surgery with axillary lymph node dissection. After the surgical treatment they had supplementary therapy. The size of the tumor was < 2 cm in 35 patients and > 2 cm in 54 patients. Their histological type was invasive duct carcinoma, 49 patients had lymph node positive and 40 had negative lymph node. Nine patients had recurrence of the disease during the 18 months of follow up. BCL2, Her2/neu, CEA and CA15-3 in sera had been monitored by ELISA before and after operation, every 6 months and at the time of diagnosis of first recurrence for 18 months.

Results: Preoperative serum levels of Her2/neu, BCL2, CA15-3 and CEA were significantly higher compared with the levels of the control group, these markers dropped significantly after operation. Univariate analysis of parameters associated with relapse showed that the clinicopathological factors (histologic grade, tumor stage and lymph nodes) and serum markers (HER2/neu, BCL2, CA15-3 and CEA) were significantly associated with recurrence of disease. Multivariate analysis of investigated parameters revealed that tumor stage, lymph nodes and serum tumor markers were significant variables predicting recurrence of tumor.

Conclusion: Serum Her2/neu, BCL2, CA15-3 and CEA in breast cancer patients were useful markers for predicting aggressive behaviorof tumor and elevated serum levels are associated with breast cancer relapse. Our relatively small study population limits the predictive power of the panels presented here, but the benefits of a serum biomarker and multimarker approach are clearly illustrated and further studies utilizing larger clinical cohorts are well warranted.

Authors: Cho Jae Yong , Lee Ahee , Kim Min Su , Park Eunhee , Chang Won Hyuk , Shin Yong-Il , Kim Yun-Hee
Published: January 2017

Background: Noninvasive brain stimulation (NBS) using repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) has recently been adopted for modulating motor function in stroke patients.

Objective: We investigated the effect of simultaneous dual-mode stimulation using rTMS and tDCS over the bilateral primary motor cortices (M1) to assess its efficacy as compared to single stimulation using rTMS for the recovery of motor function in subacute stroke patients.

Methods: Thirty subacute stroke patients were recruited in this study. In the dual-mode stimulation group, 10 Hz rTMS (90% of resting motor threshold, 1,000 pulses) was applied over the ipsilesional M1 for 20 minutes with the simultaneous application of cathodal tDCS (2 mA) on the contralesional M1. The single stimulation group underwent 10 Hz rTMS without tDCS. Ten daily sessions were conducted for two consecutive weeks. The total Fugl-Meyer (FMA-T), upper limb (FMA-UL), and lower limb (FMA-LL) scores were measured before, after, and two months later.

Results: The FMA-T and FMA- UL were significantly improved over time in both the dual and single stimulation group ( p < 0.05). However, there were significant group and time interaction effects in both the FMA-T and FMA-UL ( p < 0.05). Post-hoc analysis showed that the mean changes in the FMA-T and FMA-UL were significantly better in the dual-mode stimulation group.

Conclusion: Dual-mode NBS with the simultaneous application of 10 Hz rTMS and cathodal tDCS over the bilateral M1s was safe and superior to 10 Hz rTMS alone for improving motor function in subacute stroke patients.
Between Designer and Design: Parametric Design and Prototyping Considerations on Gaudí’s Sagrada Familia
Authors: Makert Rodrigo , Alves Gilfranco
Published: January 2017

Digital technologies have enabled new design methods, casting a reassessment of current theories of design. Rivka Oxman proposed five paradigmatic classes of digital design models according to the various relationships between the designer, conceptual content, applied design processes, and the design object. Kotnik states that catenary curve computational thinking is changing the way we think and design in architecture; it can be distinguished by three main levels of “computability”: representational, parametric and algorithmic. Kolarevic clarifies that new digital approaches to design (based on computational concepts), construction and prototyping can be achieved by computerised numerical control process (CNC). The study aims to promote the integration of theory and practice in search of a feedback loop that promotes the scientific method of knowledge production. The theoretical work intends to develop an updated understanding of the use of digital technologies. The practical experimentation analyses the Sagrada Família, designed by Antoni Gaudí, and proposes to compare digital (through the software Rhinoceros and the plug-in Grasshopper) and handmade physical models from the concept of catenary used by the Catalan architect. Referring to the Sagrada Família, Burry believes that “the continued contribution of the craftsperson is judged as a crucial partner to the digital dialogue” (Burry, 2005)
A Thematic Review of the Main Research on Construction Equipment over Recent Years
Authors: Naskoudakis Ilias , Petroutsatou Kleopatra
Published: January 2017

A considerable body of literature has been dedicated to research studies on construction equipment. Many topics were discussed and analysed, and various conclusions have been reported. However, research papers published regarding construction equipment, are highly diversified, and there is a lack of systematic analysis and classification. Hence, a complete understanding of the topic is not possible, nor is the assessment of any future research direction. A meta-analysis of the latest journal papers dedicated to construction machinery would not only delineate the fields the academic research was concentrated on but would additionally reveal potential gaps for future research. In the current study, through a systematic review of the academic literature published over the last decade, primarily identified via online databases, main research themes such as optimisation, maintenance/downtime, productivity, robotics and automation, operator competence, innovation, and environment are determined and discussed, with future research directions suggested. The outcome of this paper will facilitate future researchers to develop a body of knowledge of progress on construction equipment and its potential functions and provide future research directions on this issue.Furthermore, some pointers will be provided regarding the optimum selection of fleet equipment as a key factor for the success of any construction project. These will be given as part of the necessary holistic and strategic approach required to deliver a construction project successfully.
Solving the Telomere Replication Problem
Authors: Maestroni Laetitia , Matmati Samah , Coulon Stéphane
Published: January 2017

Telomeres are complex nucleoprotein structures that protect the extremities of linear chromosomes. Telomere replication is a major challenge because many obstacles to the progression of the replication fork are concentrated at the ends of the chromosomes. This is known as the telomere replication problem. In this article, different and new aspects of telomere replication, that can threaten the integrity of telomeres, will be reviewed. In particular, we will focus on the functions of shelterin and the replisome for the preservation of telomere integrity
Anti-Fibrotic Effect of Losartan, an Angiotensin II Receptor Blocker, Is Mediated through Inhibition of ER Stress via Up-Regulation of SIRT1, Followed by Induction of HO-1 and Thioredoxin
Authors: Kim Hyosang , Baek Chung , Lee Raymond , Chang Jai , Yang Won , Lee Sang
Published: January 2017

Endoplasmic reticulum (ER) stress is increasingly identified as modulator of fibrosis. Losartan, an angiotensin II receptor blocker, has been widely used as the first choice of treatment in chronic renal diseases. We postulated that anti-fibrotic effect of losartan is mediated through inhibition of ER stress via SIRT1 (silent mating type information regulation 2 homolog 1) hemeoxygenase-1 (HO-1)/thioredoxin pathway. Renal tubular cells, tunicamycin (TM)-induced ER stress, and unilateral ureteral obstruction (UUO) mouse model were used. Expression of ER stress was assessed by Western blot analysis and immunohistochemical stain. ER stress was induced by chemical ER stress inducer, tunicamycin, and non-chemical inducers such as TGF-β, angiotensin II, high glucose, and albumin. Losartan suppressed the TM-induced ER stress, as shown by inhibition of TM-induced expression of GRP78 (glucose related protein 78) and p-eIF2α (phosphospecific-eukaryotic translation initiation factor-2α), through up-regulation of SIRT1 via HO-1 and thioredoxin. Losartan also suppressed the ER stress by non-chemical inducers. In both animal models, losartan reduced the tubular expression of GRP78, which were abolished by pretreatment with sirtinol (SIRT1 inhibitor). Sirtinol also blocked the inhibitory effect of losartan on the UUO-induced renal fibrosis. These findings provide new insights into renoprotective effects of losartan and suggest that SIRT1, HO-1, and thioredoxin may be potential pharmacological targets in kidney diseases under excessive ER stress condition.

Authors: Jaramillo Juan , Zarzycki Artur , Galeano July , Sandoz Patrick
Published: January 2017

This article concerns the characterization of the stability and performance of a motorized stage used in laser direct writing lithography. The system was built from commercial components and commanded by G-code. Measurements use a pseudo-periodic-pattern (PPP) observed by a camera and image processing is based on Fourier transform and phase measurement methods. The results report that the built system has a stability against vibrations determined by peak-valley deviations of 65 nm and 26 nm in the x and y directions, respectively, with a standard deviation of 10 nm in both directions. When the xy-stage is in movement, it works with a resolution of 0.36 μm, which is an acceptable value for most of research and development (R and D) microtechnology developments in which the typical feature size used is in the micrometer range.
Commercial Aquaponics Approaching the European Market: To Consumers’ Perceptions of Aquaponics Products in Europe
Authors: Miličić Vesna , Thorarinsdottir Ragnheidur , Santos Maria , Hančič Maja
Published: January 2017

The first commercial aquaponics companies are starting up in Europe. The main focus has been on solving technology issues and optimizing production. However, increasing attention is now being paid to certification and regulations linked to aquaponics, as well as the marketing of products and services. The paper presents the results of a study whose main aim was to estimate consumers’ knowledge about aquaponics and their acceptance of aquaponics products in different European regions. An on-line questionnaire was administered to the general public through the aquaponics network of Food and Agriculture COST (European Cooperation in Science and Technology) Action FA1305 “The EU Aquaponics Hub—Realising Sustainable Integrated Fish and Vegetable Production for the EU” in 16 European countries. The methodology includes univariate and multivariate statistical techniques. The results show that, on average, attitudes towards aquaponics were positive, showing no significant differences between those who already knew about aquaponics and those who only heard about it through the survey. More than 50% of respondents had never heard of aquaponics, whilst more than 70% had already heard of hydroponics. No more than 17% of respondents were willing to pay more for aquaponically produced products and no more than 40% more when compared to the price of products from conventional farming. The results confirm three different clusters of potential consumers of aquaponics products. They also suggest an urgent need for implementing integrated and holistic approaches involving all stakeholders in aquaponics, in order to define a marketing plan and efficient communication strategies. This COST action, other projects and public decision makers must invest in educating consumers about aquaponics through the organization of guided tours, thematic workshops and tastings of aquaponics products in order to raise their awareness about this new technology. It is absolutely urgent that public decision makers, in cooperation with aquaponics stakeholders, address the main institutional constraints, namely the introduction of aquaponics as an economic activity and the organic certification of aquaponics products.

High magnetic fields systems is widely used in fundamental and applied research in variuos branches of science and industry. The most famous examples of such magnetic systems are tokomaks, stellators, superconducting magnets, CERN collider, ITER reactor, levitation systems. The key component of magnetic systems is inductor (solenoid). At this moment, the record magnetic fields reaches 100 T. The creation of a strong magnetic field is no longer enough just to improve designs for inductor (solenoid). Traditional electrotechnical materials and conductors can no longer withstand the huge mechanical and thermal loads, therefore, them changes to an entirely new advanced materials, for example Cu-Nb microcomposite conductors. These materials are characterized by a unique structure, excellent mechanical properties and good electrical conductivity. One of the most important and unresolved problems of high magnetic fields systems are reliable non-destructive joints and joining technologies creation. This paper reviews the strong magnetic fields systems design features, Cu-Nb conductors characteristics and structure, microcomposite conductor production specifics, application fields, joining problems and the available joining technologies. Stiprių magnetinių laukų sistemos plačiai taikomos fundamentiniams ir taikomiesiems tyrimams įvairiose mokslo šakose ir industrijoje. Tokomakai, stelaratoriai, superlaidūs magnetai, CERN kolaideris, ITER reaktorius, levitacinės sistemos – tai vieni žinomiausių tokių magnetinių sistemų pavyzdžių. Visų magnetinių sistemų svarbiausias komponentas yra induktorius (solenoidas). Rekordinis magnetinis laukas jau siekia 100 T. Stipriam magnetiniam laukui sukurti jau nepakanka vien tik tobulinti solenoidų konstrukciją. Tradicinės elektrotechninės medžiagos ir laidininkai jau negali atlaikyti didžiulių mechaninių ir temperatūrinių apkrovų. Todėl jas keičia visiškai naujos perspektyvios medžiagos, tarp jų svarbią vietą užima Cu-Nb mikrokompozitiniai laidininkai. Šios medžiagos pasižymi unikalia struktūra, puikiomis mechaninėmis savybėmis ir geru elektriniu laidumu. Viena iš svarbių neišspręstų problemų stiprių magnetinių laukų sistemose lieka patikimų neardomųjų jungčių sukūrimas ir jų patikimų sujungimo technologijų paieška, nes dauguma tokių magnetų konstrukcijų turi būti neardomos pradėjus jas eksploatuoti. Tačiau daugiausia jų konstrukcijoje laidininkams sujungti taikomos tik ardomos, deja, praktikoje dideliu patikimumu nepasižyminčios varžtinės arba lituotinės jungtys. Šiame darbe apžvelgti stiprių magnetinių laukų sistemų konstrukciniai ypatumai, perspektyvių Cu-Nb laidininkų struktūros ypatumai ir savybės, kompozitinių laidininkų gamybos specifika, taikymo sritys, sujungimo problemos ir taikytinos sujungimo technologijos.

Design of English Multimedia Teaching System Based on Diversification Theory
Authors: Lou Minsheng
Published: January 2017

Based on the diversification theory, this paper designed a multimedia technology-based English teaching system framework which is used to assist English teaching in classroom. The whole system framework consists of two parts: the part of learning resource allocation and the part of English teaching activities. Learning resource allocation is mainly to expand English learning materials from the traditional printed resources to audios, videos, animations and other forms of resources; the use of multimedia resources for teaching activities is achieved mainly through the English speech teaching and lecturing device designed with the function of playing multimedia files. In order to test the application effect of multimedia technology in English teaching, this paper chose the public course of “Vocational English” as the experimental content, and compared the effect of respectively using multimedia technology to teach freshmen of Grade 2016 and adopting the traditional teaching method to teach students of Grade 2015. The outcome shows that the use of multimedia technology in English teaching can improve students’ interest in learning, reduce their pressure of learning English, and enhance their sense of accomplishment in learning, indicating that multimedia-assisted teaching can effectively improve English teaching results.

The proposed system is used to make easy the patient and physician for accessing healthcare system. It tries to combine many functions in healthcare services for long distance monitoring system. Physiological parameters are used such as blood pressure, blood sugar, respiration, heartbeat, pulse, temperature will be received by the system then it is sent to the clinic server immediately. All of these parameters can be inputted by patients themselves while the patients are far from the clinical environment and forward to the physician for further diagnosis and medical treatment. The advantages of the proposed system are the patient will be easy to access the system through internet and easy to connect the physician from a remote area. Smartphone with multimedia features and internet connection in mobile environment can be used to perform mobile computing anywhere and anytime. It keeps real-time recording and monitoring of physiology parameters of the patients at lowest cost and at home. The physiology parameters of patient are increased to be multimedia data. By using the good quality of the multimedia data, the physician will be more precise to perform diagnosis and medical treatment to the patient. The proposed framework can be used to develop a practical web-based mobile telemonitoring system in mobile environment.
The Effectiveness of Dynamic Features of Finger Based Gestures on Smartphones’ Touchscreens for User Identification
Authors: AlShowarah Suleyman
Published: January 2017

This paper presents methodology for user identification on smartphone and mini-tablet using finger based gestures. In this paper, a set of four features, namely Signature Precision (SP), Finger Pressure (FP), Movement Time (MT), and Speed were extracted from each gesture of eight using dynamic time warping and Euclidean distance. The features are then used individually and combined for the purpose of user identification based on the Euclidean distance and the k-nearest neighbour classifier. We concluded that the best identification accuracy results from the combinations of FP and MT features where 78.46% and 78.33% were achieved on small smartphone and Mini-tablet respectively using a dataset of 50 users.
Effects of Temperature, Total Dissolved Solids, and Total Suspended Solids on Survival and Development Rate of Larval Arkansas River Shiner
Authors: Mueller Julia S. , Grabowski Timothy B. , Brewer Shannon K. , Worthington Thomas A.
Published: January 2017

Decreases in the abundance and diversity of stream fishes in the North American Great Plains have been attributed to habitat fragmentation, altered hydrological and temperature regimes, and elevated levels of total dissolved solids and total suspended solids. Pelagic-broadcast spawning cyprinids, such as the Arkansas River Shiner Notropis girardi, may be particularly vulnerable to these changing conditions because of their reproductive strategy. Our objectives were to assess the effects of temperature, total dissolved solids, and total suspended solids on the developmental and survival rates of Arkansas River Shiner larvae. Results suggest temperature had the greatest influence on the developmental rate of Arkansas River Shiner larvae. However, embryos exposed to the higher levels of total dissolved solids and total suspended solids reached developmental stages earlier than counterparts at equivalent temperatures. Although this rapid development may be beneficial in fragmented waters, our data suggest it may be associated with lower survival rates. Furthermore, those embryos incubating at high temperatures, or in high levels of total dissolved solids and total suspended solids resulted in less viable embryos and larvae than those incubating in all other temperature, total dissolved solid, and total suspended solid treatment groups. As the Great Plains ecoregion continues to change, these results may assist in understanding reasons for past extirpations and future extirpation threats as well as predict stream reaches capable of sustaining Arkansas River Shiners and other species with similar early life-history strategies.

Research has illustrated those societies who invest in a 21st century education benefits immediately by transforming an outdated system to a more sustainable approach. As the primary consumer of the world's education system, the business community needs capable, enterprising employees to compete in a global economy. Technical and Vocational Education and Training (TVET) educators worldwide must develop challenging and relevant learning environments to prepare the future workforce of tomorrow. This strategy must incorporate workforce and economic development policies in K-12 education to be sustainable. The intent of this paper is to highlight challenges that are facing the future of the global workforce and provide guidance for a more sustainable TVET system. Twenty first century pedagogy and employability skills, universally accepted certifications, public-private partnerships, and program outcomes which have the potential to significantly increase a workforce prepared to thrive in rapidly changing times will be emphasized.
A Hybridization of Gravitational Search Algorithm and Particle Swarm Optimization for Odor Source Localization
Authors: Jain Upma , Godfrey W. Wilfred , Tiwari Ritu
Published: January 2017

This paper concerns with the problem of odor source localization by a team of mobile robots. The authors propose two methods for odor source localization which are largely inspired from gravitational search algorithm and particle swarm optimization. The intensity of odor across the plume area is assumed to follow the Gaussian distribution. As robots enter in the vicinity of plume area they form groups using K-nearest neighbor algorithm. The problem of local optima is handled through the use of search counter concept. The proposed approaches are tested and validated through simulation.
On Preconditioners Based on HSS for the Space Fractional CNLS Equations
Authors: Ran Yu-Hong , Wang Jun-Gang , Wang Dong-Ling
Published: January 2017

The space fractional coupled nonlinear Schrödinger (CNLS) equations are discretized by an implicit conservative difference scheme with the fractional centered difference formula, which is unconditionally stable. The coefficient matrix of the discretized linear system is equal to the sum of a complex scaled identity matrix which can be written as the imaginary unit times the identity matrix and a symmetric Toeplitz-plusdiagonal matrix. In this paper, we present new preconditioners based on Hermitian and skew-Hermitian splitting (HSS) for such Toeplitz-like matrix. Theoretically, we show that all the eigenvalues of the resulting preconditioned matrices lie in the interior of the disk of radius 1 centered at the point (1,0). Thus Krylov subspace methods with the proposed preconditioners converge very fast. Numerical examples are given to illustrate the effectiveness of the proposed preconditioners.
Спектр прямоугольных решеток квантовых волноводов
Authors: Nazarov Sergei Aleksandrovich
Published: January 2017

Получены асимптотические формулы для спектральных сегментов тонкой ($h\ll 1$) прямоугольной решетки квантовых волноводов, описываемой задачей Дирихле для оператора Лапласа. Установлено, что общепринятая модель квантового графа с традиционными условиями Кирхгофа в узлах дает неправильное представление о строении спектра решетки. Оказывается, длины спектральных сегментов являются бесконечно малыми $O(e^{-\delta/h})$, $\delta>0$, и $O(h)$ при $h\to+0$, и между ними возникают лакуны с шириной $O(h^{-2})$ и $O(1)$ соответственно в низко- и среднечастотных диапазонах спектра. Первый спектральный сегмент порожден (единственным) собственным числом в дискретном спектре бесконечного крестообразного волновода $\Theta$. Проверенное отсутствие ограниченных решений у задачи в $\Theta$ на пороговой частоте означает, что правильная модель решетки - граф с условиями Дирихле в узлах, распадающийся на два бесконечных набора идентичных звеньев-отрезков. При помощи возмущений конечного набора перемычек построены точки дискретного спектра решетки в любом заданном наперед количестве как ниже существенного спектра, так и внутри лакун.

Authors: Andrianov Aleksandr Andreevich , Andrianov Vladimir Andreevich , Espriu Domenec , Kolevatov Sergei Sergeevich
Published: January 2017

Рассматриваются процессы в компактных звездах, возникающие при возможном образовании псевдоскалярного конденсата в конечных объемах. В работе не делается конкретных предположений о природе конденсата. В предположении, что в областях с изменяющейся псевдоскалярной плотностью распространение фотонов можно описать в рамках электродинамики Максвелла-Черна-Саймонса, найдены коэффициенты отражения/прохождения для областей с разными плотностями. Проведено исследование фермионного спектра в присутствии аксиального поля с учетом градиента псевдоскалярного конденсата, а также исследовано влияние модифицированных спектров фотонов и фермионов на процесс остывания компактных звезд.
