Classification of E-Nose Aroma Data of Four Fruit Types by ABC-Based Neural Network
Authors: Adak M. , Yumusak Nejat
Published: February 2016

Electronic nose technology is used in many areas, and frequently in the beverage industry for classification and quality-control purposes. In this study, four different aroma data (strawberry, lemon, cherry, and melon) were obtained using a MOSES II electronic nose for the purpose of fruit classification. To improve the performance of the classification, the training phase of the neural network with two hidden layers was optimized using artificial bee colony algorithm (ABC), which is known to be successful in exploration. Test data were given to two different neural networks, each of which were trained separately with backpropagation (BP) and ABC, and average test performances were measured as 60% for the artificial neural network trained with BP and 76.39% for the artificial neural network trained with ABC. Training and test phases were repeated 30 times to obtain these average performance measurements. This level of performance shows that the artificial neural network trained with ABC is successful in classifying aroma data.

Authors: Andújar Márquez José , Martínez Bohórquez Miguel , Gómez Melgar Sergio
Published: February 2016

This paper presents a methodology and instrumentation system for the indirect measurement of the thermal diffusivity of a soil at a given depth from measuring its temperature at that depth. The development has been carried out considering its application to the design and sizing of very low enthalpy geothermal energy (VLEGE) systems, but it can has many other applications, for example in construction, agriculture or biology. The methodology is simple and inexpensive because it can take advantage of the prescriptive geotechnical drilling prior to the construction of a house or building, to take at the same time temperature measurements that will allow get the actual temperature and ground thermal diffusivity to the depth of interest. The methodology and developed system have been tested and used in the design of a VLEGE facility for a chalet with basement at the outskirts of Huelva (a city in the southwest of Spain). Experimental results validate the proposed approach.
Exploitation of Ubiquitous Wi-Fi Devices as Building Blocks for Improvised Motion Detection Systems
Authors: Soldovieri Francesco , Gennarelli Gianluca
Published: February 2016

This article deals with a feasibility study on the detection of human movements in indoor scenarios based on radio signal strength variations. The sensing principle exploits the fact that the human body interacts with wireless signals, introducing variations of the radiowave fields due to shadowing and multipath phenomena. As a result, human motion can be inferred from fluctuations of radiowave power collected by a receiving terminal. In this paper, we investigate the potentialities of widely available wireless communication devices in order to develop an improvised motion detection system (IMDS). Experimental tests are performed in an indoor environment by using a smartphone as a Wi-Fi access point and a laptop with dedicated software as a receiver. Simple detection strategies tailored for real-time operation are implemented to process the received signal strength measurements. The achieved results confirm the potentialities of the simple system here proposed to reliably detect human motion in operational conditions.

Published: February 2016

This paper elucidates the fundamentals of visible light communication systems that use the rolling shutter mechanism of CMOS sensors. All related information involving different subjects, such as photometry, camera operation, photography and image processing, are studied in tandem to explain the system. Then, the system performance is analyzed with respect to signal quality and data rate. To this end, a measure of signal quality, the signal to interference plus noise ratio (SINR), is formulated. Finally, a simulation is conducted to verify the analysis.

Authors: Tao Sulin , Shen Shuanghe , Li Yuhong , Wang Qi , Gao Ping , Mugume Isaac
Published: February 2016

A sensitivity analysis of the responses of crops to the chosen production adaptation options under regional climate change was conducted in this study. Projections of winter wheat production for different sowing dates and cultivars were estimated for a major economic and agricultural province of China from 2021 to 2080 using the World Food Study model (WOFOST) under representative concentration pathways (RCPs) scenarios. A modeling chain was established and a correction method was proposed to reduce the bias of the resulting model-simulated climate data. The results indicated that adjusting the sowing dates and cultivars could mitigate the influences of climate change on winter wheat production in Jinagsu. The yield gains were projected from the chosen sowing date and cultivar. The following actions are recommended to ensure high and stable yields under future climate changes: (i) advance the latest sowing date in some areas of northern Jiangsu; and (ii) use heat-tolerant or heat-tolerant and drought-resistant varieties in most areas of Jiangsu rather than the currently used cultivar. Fewer of the common negative effects of using a single climate model occurred when using the sensitivity analysis because our bias correction method was effective for scenario data and because the WOFOST performed well for Jiangsu after calibration.
Multiscale Spatio-Temporal Dynamics of Economic Development in an Interprovincial Boundary Region: Junction Area of Tibetan Plateau, Hengduan Mountain, Yungui Plateau and Sichuan Basin, Southwestern China Case
Authors: Zhang Jifei , Deng Wei
Published: February 2016

An interprovincial boundary region is a new subject of economic disparity study in China. This study explored the multi-scale spatio-temporal dynamics of economic development from 1995 to 2010 in the interprovincial boundary region of Sichuan-Yunnan-Guizhou, a mountain area and also the junction area of Tibetan Plateau, Hengduan Mountain, Yungui Plateau and Sichuan Basin in southwestern China. A quantitative study on county GDP per capita for different scales of administrative regions was conducted using the Theil index, Markov chains, a geographic information system and exploratory spatial data analysis. Results indicated that the economic disparity was closely related with geographical unit scale in the study area: the smaller the unit, the bigger the disparity, and the regional inequality gradually weakened over time. Moreover, significant positive spatial autocorrelation and clustering of economic development were also found. The spatial pattern of economic development presented approximate circle structure with two cores in the southwest and northeast. The Panxi region in the southwest core and a part of Hilly Sichuan Basin in the northeast core were considered to be hot spots of economic development. Most areas in the east and central region were persistently trapped in the low level of a balanced development state, with a poverty trap being formed in the central and south part. Geographical conditions and location, administrative barriers and the lack of effective growth poles may be the main reasons for the entire low level of balanced development. Our findings suggest that in order to achieve a high level of balanced development, attention should be paid beyond developing transportation and other infrastructure. Breaking down the rigid shackles of administrative districts that hinder trans-provincial cooperation and promoting new regional poles in the Yunnan-Guizhou region may have great significance for the study area.
Development of a Resource Allocation Model Using Competitive Advantage
Authors: Lee Sangwon , Ahn Suneung , Park Changsoon , Park You-Jin
Published: February 2016

In general, during decision making or negotiations, the investor and the investee may often have different opinions which result in conflicts. So, an objective standard to mitigate potential conflicts between investors and investees should be provided since it is highly important that rational decisions must be made when choosing investments from various options. However, the models currently used come with some problems for several reasons, for instance, the arbitrariness of the evaluator, the difficulty in understanding the relationships that exist among the various investment options (that is, alternatives to investments), inconsistency in priorities, and simply providing selection criteria without detailing the proportion of investment in each option or evaluating only a single investment option at a time without considering all options. Thus, in this research, we present a project selection model which can enable reasonable resource allocation or determination of return rates by considering the core competencies for various investment options. Here, core competency is based on both performance and ability to create a competitive advantage. For this, we deduce issue-specific structural power indicators and analyze quantitatively the resource allocation results based on negotiation power. Through this, it is possible to examine whether the proposed project selection model considers core competencies or not by comparing several project selection models currently used. Furthermore, the proposed model can be used on its own, or in combination with other methods. Consequently, the presented model can be used as a quantitative criterion for determining behavioral tactics, and also can be used to mitigate potential conflicts between the investor and the investee who are considering idiosyncratic investments, determined by an interplay between power and core competency.

Published: February 2016

Understanding the spatiotemporal distribution pattern of hail disaster risk for cotton is crucial in mitigating hail disaster and promoting the sustainability of cotton farming. Based on such indexes as hail disaster frequency, spatiotemporal exposure, and vulnerability of cotton, we assess hail disaster risk for cotton, and analyze its spatiotemporal pattern and evolution in Mainland China from 1950 to 2009, supported by geographic information system (GIS). The following conclusions are drawn: (1) The proposed risk assessment method reveals the spatiotemporal difference of hail disaster risk for cotton at the county level. (2) Hail disaster risk for cotton is low in China, except for north of the North China Plain and the cotton-planting areas in Xinjiang Uygur Autonomous Region. From 1950 to 2009, hail disaster risk for cotton gradually increased. (3) The descending orders of hail disaster risk levels for cotton are bud stage, seedling stage, sowing and seeding stage, boll stage, and boll opening stage. The growth period with the highest risk varies across the cotton-planting areas. (4) The results of this paper are important for developing hail disaster prevention and reduction measures.
The Decoupling of Resource Consumption and Environmental Impact from Economic Growth in China: Spatial Pattern and Temporal Trend
Authors: Zhang Zilong , Xue Bing , Pang Jiaxing , Chen Xingpeng
Published: February 2016

Unprecedented economic achievement in China has occurred along with rising resource consumption and waste productions levels. The goal of sustainability requires the decoupling of economic growth from resource consumption (resource decoupling) and environmental degradation (impact decoupling). For this paper, the performances of resource decoupling (energy and water) and impact decoupling (wastewater, SO2 and CO2) in China were evaluated, and the spatial pattern and temporal trend of decoupling performance were investigated by using the rescaled range analysis (R/S). The results indicate the following. (1) The performance of resource decoupling during the investigated period is worse than that of traditional impact (SO2 and wastewater) decoupling, but better than that of the CO2 emission. Additionally, the decoupling performances of energy consumption and related pollutant emission (except CO2) are better than that of water usage and wastewater discharge; (2) The decoupling performance of energy consumption, SO2 and CO2, has substantially improved from the 10th Five-Year Planning Period (FYP) (2001–2005) to the 11th FYP (2006–2010), which indicates that the decoupling performance is highly related the environmental policy; (3) The spatial disparities of the performance of resource and impact decoupling are declining, which indicates the existence of cross-province convergence in decoupling performance; (4) The decoupling performance of SO2 and water usage in most of regions shows an improving trend. Inversely, the decoupling performance of energy consumption, CO2 emission, and wastewater discharge in most regions show a decreasing trend; (5) China needs more stringent water-saving targets and wastewater discharge standards; better policy efforts to improve the water recycling level both in agricultural, industrial and municipal level are required to prevent the decreasing trend of the decoupling performance.
Paulistine—The Functional Duality of a Wasp Venom Peptide Toxin
Authors: Arcuri Helen , Gomes Paulo , De Souza Bibiana , Dias Nathalia , Brigatte Patrícia , Stabeli Rodrigo , Palma Mario
Published: February 2016

It has been reported that Paulistine in the venom of the wasp Polybia paulista co-exists as two different forms: an oxidized form presenting a compact structure due to the presence of a disulfide bridge, which causes inflammation through an apparent interaction with receptors in the 5-lipoxygenase pathway, and a naturally reduced form (without the disulfide bridge) that exists in a linear conformation and which also causes hyperalgesia and acts in the cyclooxygenase type II pathway. The reduced peptide was acetamidomethylated (Acm-Paulistine) to stabilize this form, and it still maintained its typical inflammatory activity. Oxidized Paulistine docks onto PGHS2 (COX-2) molecules, blocking the access of oxygen to the heme group and inhibiting the inflammatory activity of Acm-Paulistine in the cyclooxygenase type II pathway. Docking simulations revealed that the site of the docking of Paulistine within the PGHS2 molecule is unusual among commercial inhibitors of the enzyme, with an affinity potentially much higher than those observed for traditional anti-inflammatory drugs. Therefore, Paulistine causes inflammatory activity at the level of the 5-lipooxygenase pathway and, in parallel, it competes with its reduced form in relation to the activation of the cyclooxygenase pathway. Thus, while the reduced Paulistine causes inflammation, its oxidized form is a potent inhibitor of this activity.

Published: February 2016

Si le conte traditionnel est depuis longtemps une source pour les sciences humaines, le conte moderne représente aussi un outil heuristique fort efficace : équivalent de l’expérience de pensée, il sert au chercheur ; canal de vulgarisation pour diffuser les résultats de la recherche, il sert au didacticien. Toutefois, il ne saurait s’utiliser à tort et à travers : construire un récit et l’exploiter de manière optimale ne peut se faire qu’en tenant compte du contexte de réception, afin d’en déterminer la pertinence et de choisir le support et la langue appropriés.

L’auteur retrace, à travers différentes périodes, l’histoire de la marche comme pratique esthétique. Enjambant des frontières invisibles, la marche semble s’avérer être un outil puissant pour reconstituer la géographie complexe du monde urbain.
Linguistic Characteristics of Commercial and Social Advertising Slogans
Authors: Skorupa Pavel , Dubovičienė Tatjana
Published: February 2016

The current paper presents the analysis of linguistic characteristics of commercial and social advertising slogans. There is no uniform definition of the advertising slogan in the scientific literature, therefore, an attempt to provide the definition of a slogan in the context of marketing communication was made. One of the main functions of both social and commercial advertising is to provide information to the target audience and make it act in a way desired by the advertisers. As language, either spoken or written, has a powerful influence over people and their behaviour, the article analysis the language of advertising from the linguistic point of view and focuses on the phonological and semantic characteristics of slogans for commercial and social advertising campaigns. The analysis of 110 English slogans (55 commercial and 55 social advertising campaigns) showed the frequent use of both sound techniques and figurative language in commercial advertising slogans, which make the slogans more memorable, attractive and highlighting the advertised brand in a positive way. In contrast, the sound techniques and figurative language are scarce in slogans for social advertising campaigns.
A MODEL FOR THE DUST ENVELOPE OF THE SILICATE CARBON STAR IRAS 09425-6040
Authors: Suh Kyung-Won
Published: February 2016

IRAS 09425-6040 (I09425) is a silicate carbon star with conspicuous crystalline silicate and water-ice features and emission excesses in the far-infrared and millimeter (mm) wavelength ranges. To understand properties of the dust envelope of I09425, we propose a physical model based on the observations and known properties of asymptotic giant branch stars and dust. We perform radiative transfer model calculations using multiple dust shells and disks with various dust species. We compare the model results with the observed spectral energy distribution (SED) acquired with different telescopes. We find that the physical model for I09425 using multiple shells of carbon and silicate dust and multiple disks of amorphous and crystalline silicates reproduces the observed SED fairly well. This object looks to have detached cold O-rich (silicate and water-ice) dust shells, which could be remnants of the recent chemical transition from O to C and an inner C-rich dust shell. A long-lived thin disk of very large silicate grains can reproduce the emission excess in the mm wavelength band and a recently formed thick disk of crystalline silicates can reproduce the prominent emission features in the spectral range 8–45 μm. The highly crystallized silicates could be recently formed by high temperature annealing due to the last O-rich superwind just before the chemical transition of the central star. I09425 could be a rare object that has the remnants of past O-rich stellar winds in the outer shells as well as in the circumbinary disks.
POLYCYCLIC AROMATIC HYDROCARBON EMISSION IN SPITZER/IRS MAPS. I. CATALOG AND SIMPLE DIAGNOSTICS

Published: February 2016

We present a sample of resolved galactic H ii regions and photodissociation regions (PDRs) observed with the Spitzer infrared spectrograph in spectral mapping mode between the wavelengths of 5–15 μm. For each object we have spectral maps at a spatial resolution of ∼4″ in which we have measured all of the mid-infrared emission and absorption features. These include the polycyclic aromatic hydrocarbon (PAH) emission bands, primarily at 6.2, 7.7, 8.6, 11.2, and 12.7 μm, as well as the spectral emission lines of neon and sulfur and the absorption band caused by silicate dust at around 9.8 μm. In this work we describe the data in detail, including the data reduction and measurement strategies, and subsequently present the PAH emission band intensity correlations for each of the objects and the sample as a whole. We find that there are distinct differences between the sources in the sample, with two main groups: the first comprising the H ii regions and the second the reflection nebulae (RNe). Three sources—the reflection nebula NGC 7023, the Horsehead nebula PDR (an interface between the H ii region IC 434 and the Orion B molecular cloud), and M17—resist this categorization, with the Horsehead PDR points mimicking the RNe and the NGC 7023 fluxes displaying a unique bifurcated appearance in our correlation plots. These discrepancies seem to be due to the very low radiation field experienced by the Horsehead PDR and the very clean separation between the PDR environment and a diffuse environment in the NGC 7023 observations.
“Won't You Be My Patient?”: Preparing Theater Students as Standardized Patients
Authors: Hart Julie A. , Chilcote Deborah R.
Published: February 2016

Background:

Simulation in nursing education is a well-supported teaching strategy. High-fidelity manikins provide students with an opportunity to practice nursing care in a safe environment. Yet, limitations such as lack of realism and inability to practice therapeutic communication have been reported. However, standardized patients (SPs)—actors trained to portray patients with medical issues—provide students with realistic patient situations and opportunities to develop essential skills.

Method:

A literature review identified barriers to utilizing SP-based simulations. Issues such as financial, human resource, and quality control concerns were identified.

Results:

Based on identified barriers, an innovative, interdisciplinary course to prepare theater students to portray patients for simulations is proposed. This proposed course could potentially eliminate identified barriers and increase use of SPs.

Conclusion:

Because this is a proposed course, the authors recommend testing of the innovation to determine the effectiveness for both nursing and theater students. [

Dynamic Simulation of Crank-group Driving Mechanism with Clearance
Authors: Liu Yansong , Cao Jujiang
Published: February 2016

The crank-group driving mechanism includes a group of redundant constraints. This mechanism can move as a driving mechanism under ideal conditions, but it may be stuck because of the processing errors in practical applications. So, some clearances are reserved between the pin hole and the pin to ensure that the crank-group driving mechanism can achieve normal movement, but these clearances inevitably affect the dynamic performance of the output member. In this paper, the dynamic simulation model of the crank-group driving mechanism is established by NX/Motion Simulation which is based on the 3-D model of planar link mechanism. The comparative analysis is made about the dynamic characteristics of the mechanism which is influenced by different clearances, different angular velocity, different damping, and make a qualitative analysis how the clearances affects the dynamic performance of the output member. The simulation results also show that appropriately increasing the angular velocity, increasing stiffness and damping of the components can effectively inhibit the adverse influences of clearance on the dynamic characteristics of the mechanism.

Some Studies in Multi-Storage Inventory System
Authors: Mondal Shyamal Kumar
Published: February 2016

In this chapter, a multi-storage inventory system has been considered to develop a deterministic inventory model in finite planning horizon. Realistically, it is shown that due to large stock and insufficient space of existing own warehouse (OW); excess items are stored in single rented warehouse (RW). Due to different preserving facilities and storage environment, inventory holding cost is considered to be different in different warehouses. Here, the replenishment cycle lengths are of equal length, the demand rate is a continuous linear increasing function of time and partially backlogged shortages are allowed in all cycles. In each cycle, the replenishment cost is assumed to be dependent linearly on lot size and the stocks of RW are also transported to OW in continuous release pattern. The model is formulated as a constrained non-linear mixed integer cost objective function under single management. Finally, results with a sensitivity analysis have been shown with the help of a real coded GA.

We have established the equivalent queueing network to analyze the various performance measures with numerical illustration and graph.
Can Educational Approaches Help to Revolutionize Quantitative Solutions for Climate Change?
Authors: Ahamer Gilbert
Published: February 2016

In order to apply web-supported education to solve one of the foremost issues revolutionizing our life on the planet Earth, this chapter focuses on global climate change and its driving forces from a both didactic and scientific perspective. It describes how to “tackle the task of a transition through technological targets” (T5). It suggests a technology-oriented quantitative approach based on the “Global Change Data Base” for the sharing of hypotheses, scenarios, political applications, and didactic strategies related to planning, developing, managing, using and evaluating technological targets towards climate protection and global sustainability in academia, administration, education and policy consulting. The complete logical chain of cause and effect from social drivers to CO2 emission and climate change is used as an educational basis for advocating the global necessity and potential technological feasibility of CO2 reduction. Students negotiate global structural transitions and a set of CO2 abatement measures (similar to the game “Surfing Global Change”).
Design Agency

Published: February 2016

The race and gender gap in US STEM education achievement reflects the legacy of historical forces which include colonialism and the exclusion of women in higher education. But it also reflects the decontextualized character of standard educational forms. We report on cSELF (Computer Science Education from Life), an intervention which brings together two alternative approaches. The “creative medium” approach offers a blank slate in which youth create their own innovations. The “indigenous knowledge” approach helps to translate traditional math and computing concepts into contemporary forms. Using the concept of “design agency” the authors describe how this merging of abstract formal structures, material creative practice, and cultural knowledge can improve underrepresented student performance, and foster learning practices in computing that offer broader forms of social expression and deeper STEM engagement for all students.

Teaching Wireless Network Fundamentals Using Low-Cost Wi-Fi Devices
Authors: Sarkar Nurul I.
Published: February 2016

Teaching wireless networking fundamentals is often difficult because many students appear to find the subject technical, and dry when presented in traditional lecture format. To overcome this problem, we provide an opportunity for experiential learning where students can learn wireless networking fundamentals by hands-on practical activities using low-cost Wi-Fi (wireless fidelity) devices such as wireless cards and access points. Students can easily set up and configure networks using wireless cards and access points more effectively. By measuring network performance such as throughput and end-to-end delays, students are able to gain a deeper understanding of wireless networking. The effectiveness of Wi-Fi-based practical activities has been evaluated by students and the teaching team. This chapter reports on the overall effectiveness of teaching and learning of wireless network using radially available low-cost Wi-Fi cards and access points.
Technology Integration and Innovation during Reflective Teaching
Authors: Baporikar Neeta
Published: February 2016

With emerging innovations, the use of technology tools to make learning process effective is foreseeable. Hence, appropriate incorporation of technology can make a valuable contribution to the learning and undoubtedly reflection is core to learning. With today's twenty-first century learners, it is important that educators advocate integrating twenty-first century skills into their reflection activities. In Ray and Coulter's study (2008) on the use of blogs by teachers for reflective purposes, the authors conclude that “Teachers would benefit from combining the skills of technology and reflection,” and that “these kinds of public technologies provide a way for teachers not only to analyze their own practice, but also to share their reflections with others” (p. 20). Teachers and students can now avail themselves of various online and computer-based applications in order to reflect on their learning. As technology integration process takes time and efforts, a systemic plan is required. This paper examines reflective teaching through concerted technology integration.

Most queries posed on them are on-line analytical queries, which are complex and computation intensive in nature and have high query response times when processed against a large data warehouse. This time can be substantially reduced by materializing pre-computed summarized views and storing them in a data warehouse. All possible views cannot be materialized due to storage space constraints. Also, an optimal selection of subsets of views is shown to be an NP-Complete problem. This problem of view selection has been addressed in this paper by selecting a beneficial set of views, from amongst all possible views, using the swarm intelligence technique Marriage in Honey Bees Optimization (MBO). An MBO based view selection algorithm (MBOVSA), which aims to select views that incur the minimum total cost of evaluating all the views (TVEC), is proposed. In MBOVSA, the search has been intensified by incorporating the royal jelly feeding phase into MBO. MBOVSA, when compared with the most fundamental greedy based view selection algorithm HRUA, is able to select comparatively better quality views.

Purpose: To identify clinico-radiological distinguishing features in various types of spinal arteriovenous malformations (AVM) with an aim to define the role of surgical intervention. Materials and Methods: Hero's modified Di Chiro classification differentiated four types of spinal AVMs on digital subtraction angiogram (DSA) in 74 patients: I. Dural arteriovenous fistulae (n = 35, 47.3%); II. Glomus/intramedullary (n = 13, 17.6%); III. Juvenile/metameric (n = 4, 5.4%); and, IV. Ventral perimedullary fistula (n = 21, 28.4%). A patient with extradural AVM remained unclassified. Demographic profiles, DSA features and reason for surgical referral were recorded. Statistical comparison of discrete variables like gender, spinal cord level, presentation and outcome was made using Chi-square test; and, continuous variables like age, feeder number, duration of symptoms and number of staged embolizations by one way analysis of variance with Boneferoni post hoc comparison. Embolization alone (n = 39, 52.7%), surgery alone (n = 16, 21.6%), and combined approach (n = 4, 5.4%) were the treatments offered (15 were treated elsewhere). Results: Type I-AVM occurred in significantly older population than other types (P = 0.01). Mean duration of symptoms was 13.18 ± 12.8 months. Thoracic cord involvement predominated in type-I and III AVMs (P = 0.01). Number of feeding arteries were 1 in 59.7%; 2 in 29.0%; and, multiple in 11.3% patients, respectively. Staged embolization procedures in type-III AVM were significant (P < 0.01). Surgical referral was required due to: Vessel tortuosity/insufficient parent vessel caliber (n = 7); residual AVM (n = 4); low flow AVM (n = 3); and, multiple feeders (n = 2). Check DSA (n = 34) revealed complete AVM obliteration in 26 and minor residual lesion in eight patients. Neurological status improved in 26 and stabilized in 25 patients. Conclusions: Differentiating between Type I-IV AVMs has a significant bearing on their management. Surgical intervention should be considered as an important adjunct/alternative to therapeutic embolization.
A Case of Cystic Adventitial Degeneration of the Left Popliteal Artery Diagnosed by Intravascular Ultrasound

An 87-year-old male was admitted with intermittent claudication of the left calf. We performed lower extremity angiography, which revealed stenosis of the left popliteal artery. Intravascular ultrasound (IVUS) image correctly identified the cystic appearance of visualized extravascular hypodensity, causing extrinsic compression of the lumen. We diagnosed the condition as cystic adventitial degeneration (CAD) of the popliteal artery. We operated a resection of a cyst with the artery and replaced the autovein graft (saphenous vein). After surgery, the patient was free of symptoms. CAD is a rare disease; thus, our IVUS findings may provide unique diagnostic clues in patients with CAD.
Some results on weighted subquadratic Lane–Emden Elliptic Systems in unbounded domains
Authors: Barile Sara , Salvatore Addolorata
Published: February 2016

We study a nonlinear elliptic system of Lane–Emden type in

\mathbb R^N, N ≥ 3

, which is equivalent to a fourth order quasilinear elliptic equation involving a suitable ‘‘sublinear’’ term. Thanks to some compact imbeddings in weighted Sobolev spaces, existence and multiplicity results are proved by means of a generalized Weierstrass Theorem and a variant of the Symmetric Mountain Pass Theorem. These results apply in particular to a biharmonic equation under Navier conditions in

\mathbb R^N

.
Higher order Pizzetti’s formulas
Authors: Łysik Grzegorz
Published: February 2016

We introduce integral mean value functions which are averages of integral means over spheres/balls and over their images under the action of a discrete group of complex rotations. In the case of real analytic functions we derive higher order Pizzetti’s formulas. As applications we obtain a maximum principle for polyharmonic functions and a characterization of convergent solutions to higher order heat type equations.
A new nonautonomous chain rule in BV
Authors: De Cicco Virginia
Published: February 2016

The aim of this note is to present a new nonautonomous chain rule formula for the distributional derivative of the composite function

v(x) = B(x,u(x))

, where

u : \mathbb R^N \to \mathbb R

is a scalar function of bounded variation and

B

admits a special integral form in terms of a locally bounded function

b(x,t)

, with

b(\cdot. t)

of bounded variation. It is an useful tool especially in view to applications to semicontinuity results for integral functional (see [1, 8, 9, 10]) and to conservation laws (see [5, 6]).
Isotropic $p$-harmonic systems in 2D Jacobian estimates and univalent solutions
Authors: Iwaniec Tadeusz , Koski Aleksis , Onninen Jani
Published: February 2016

The core result of this paper is an inequality (rather tricky) for the Jacobian determinant of solutions of nonlinear elliptic systems in the plane. The model case is the isotropic (rotationally invariant)

\,p\,

-harmonic system

\mathrm{div} \|Dh|^{p-2} Dh =0 ,\quad h = (u, v) \in \mathcal W^{1,p}(\Omega, \mathbb R^2), 1 < p < \infty,

as opposed to a pair of scalar

p

-harmonic equations:

\mathrm{div} |\nabla u|^{p-2} \nabla u =0 \quad \mathrm{and} \quad \mathrm{div} |\nabla v|^{p-2} \nabla v=0

Rotational invariance of the systems in question makes them meaningful, both physically and geometrically. An issue is to overcome the nonlinear coupling between

\,\nabla u\,

and

\, \nabla v \,

. In the extensive literature dealing with coupled systems various differential expressions of the form

\,\Phi (\nabla u\,,\nabla v )\,

were subjected to thorough analysis. But the Jacobian determinant\linebreak

\det Dh

= u_x v_y - u_y v_x\,

was never successfully incorporated into such analysis. We present here new nonlinear differential expressions of the form

\Phi(|Dh|, \det Dh )\,

and show they are superharmonic, which yields much needed lower bounds for

\, \det Dh\,

. To illustrate the utility of such bounds we extend the celebrated univalence theorem of Radó–Kneser–Choquet on harmonic mappings (

p=2

) to the solutions of the coupled

p

-harmonic system.
Bi-Lipschitz pieces between manifolds
Authors: David Guy C.
Published: February 2016

A well-known class of questions asks the following: if

X

and

Y

are metric measure spaces and

f : X \to Y

is a Lipschitz mapping whose image has positive measure, then must

f

have large pieces on which it is bi-Lipschitz? Building on methods of David and Semmes, we answer this question in the affirmative for Lipschitz mappings between certain types of Ahlfors

s

-regular, topological

d

-manifolds. In general, these manifolds need not be bi-Lipschitz embeddable in any Euclidean space. To prove the result, we use some facts on the Gromov–Hausdorff convergence of manifolds and a topological theorem of Bonk and Kleiner. This also yields a new proof of the uniform rectifiability of some metric manifolds.
