Uniform Controllability of a Stokes Problem with a Transport Term in the Zero-Diffusion Limit

In this paper we consider a Stokes system with Navier-slip boundary conditions. The main results concern the behaviour of the cost of null controllability with respect to the diffusion coefficient when the control acts in the interior. In particular, we prove in the square that for a sufficiently large time the cost decays exponentially as the diffusion coefficient vanishes, whereas in the cube we prove that for most of the control domains and for any time T > 0 the cost explodes exponentially as the diffusion coefficient vanishes.
Body-Centric Radio Propagation Channels: characteristics and models

Body-centric wireless communication systems (BWCSs) which connect electronic devices placed at various parts of the human body are key components of future wireless systems. Recently a lot of research has been focused on the BWCS in the scope of a wireless personal area network (WPAN) and a wireless body area network (WBAN). Comprehensive channel knowledge and accurate channel models are the basis of an optimized system design. The human body influences to the antennas and propagation channels have been deeply investigated in mobile communications since the start of the 1990’s. However the body effects in the BWCS is different in several aspects. Firstly, the frequency band of the mobile communication systems is between 1 and 2 GHz while the BWCS may operate on higher frequencies above 5 GHz and on an ultra-wideband (UWB) frequency band between 3.1 and 10.6 GHz. Secondly, the radio links in the mobile communication are mainly outdoor-outdoor and indoor-outdoor channels. On the other hand most BWCSs target on indoor short range (< 10m in WPAN, < 2m in WBAN) radio communications. Furthermore, the devices in the BWCS can be much smaller than a handset and placed on a variety of body positions. Therefore, the BWCS channel requires further investigations. This thesis focuses on the characterization and modeling of both WPAN and WBAN radio channels. Body shadowing plays a key role in short range body-to-body communications since received signal is attenuated significantly due to body blockage. A correlation based stochastic model with correlated shadowing (CBSM-CS) for body-to-body multipleinput multiple-output (MIMO) radio channels is proposed based on channel characterizations derived from a series of channel experiments. The model introduces a shadowing matrix to represent unbalanced and correlated body shadowing effects. To the authors’ knowledge, this is one of the first MIMO channel models including the body shadowing effects in open literature. It is disclosed that shadowing standard deviation is dominant to the ergodic capacity while shadowing correlations between the antennas significantly affect the outage capacity. The UWB is a promising technology for the on-body BWCS. The UWB on-body
Generating lexical Resources for Opinion Mining in Arabic language automatically

In this work we present SENTIRDI, a lexical resource explicitly devised for supporting sentiment classification and opinion mining applications. We confront the task of deciding whether a given Arabic term has a positive connotation, or a negative connotation, or has no subjective connotation at all; this problem thus subsumes the problem of determining subjectivity and the problem of determining orientation. We tackle this problem by bootstrapping from three small sets of terms (Positive, Objective, and Negative seed sets) and increase sets consequently by applying lexical relation that is available in RDI Lexical Semantic Data Base(RDILSDB) until cover all Arabic semantic fields.
Dynamic Packet Forwarding Verification in SDN

Like traditional IP networking, the emerging Software-Defined Networking (SDN) technology is vulnerable to sophisticated attacks against packets and their forwarding behaviors. However, existing proposals of packet forwarding verification for IP networking cannot be directly applied to the current SDN deployment due to the limited functionalities and resources in commercial off-the-shelf (COTS) SDN switches. We propose DynaPFV, a dynamic packet forwarding verification mechanism that is capable of detecting various sophisticated attacks against packet forwarding. DynaPFV leverages the controllability of SDN to examine both packets and flow statistics across a network of switches to detect violation of packet integrity and forwarding behaviors. To mitigate the verification overhead, DynaPFV dynamically adjusts the rates of packet sampling and flow statistics collection based on the prior detection results in order to preserve the verification accuracy. Furthermore, DynaPFV makes changes to the SDN controller only, and is directly deployable atop COTS SDN switches without modifications. We conduct theoretical analysis on the trade-off between performance and accuracy in our dynamic verification approach. We further prototype DynaPFV using the open-source Floodlight controller, and evaluate our DynaPFV prototype using Mininet simulations and hardware testbed experiments. DynaPFV achieves over 97 percent of verification accuracy only with less than 5 percent of throughput degradation and less than 10 percent of additional forwarding delays.
ASSESSMENT OF SELECTED ECO-FRIENDLY PESTICIDES ON AMRASCA BIGUTTULA BIGUTTULA OF OKRA CROP IN CENTRAL REGION OF UTTAR PRADESH , INDIA

1 Corrosion Inhibition Mechanism and Efficiency 2 Differentiation of Dihydroxybenzene Isomers 3 towards Aluminium Alloy 5754 in Alkaline Media 4

15 Selection of efficient corrosion inhibitors requires detailed knowledge regarding interaction 16 mechanism, which depends on the type and amount of functional groups within the inhibitor 17 molecule. Position of functional groups between different isomers is often overlooked but not less 18 important since factors like steric hinderance may significantly affect the adsorption mechanism. 19 In this study we have presented how different dihydroxybenzene isomers interact with aluminium 20 alloy 5754 surface, reducing its corrosion rate in bicarbonate buffer (pH = 11). We have shown the 21 highest inhibition efficiency among tested compounds belongs to catechol at 10 mM concentration, 22 although differences were moderate. Utilization of novel impedance approach to adsorption 23 isotherm determination allowed to confirm that while resorcinol chemisorbs on aluminium 24 surface, catechol and quinol follows ligand exchange model of adsorption. Unlike catechol and 25 quinol, the protection mechanism of resorcinol is bound to interaction with insoluble aluminium 26 corrosion products layer and was only found efficient at concentration of 100 mM (98.7%). The 27 aforementioned studies were confirmed with Scanning Electron Microscopy and X-ray 28 Photoelectron Spectroscopy analyses. 29 There is a significant increase of the corrosion resistance offered by catechol at 10 mM after 24 h 30 exposure in electrolyte: from 63 to 98%, with only negligible changes in inhibitor efficiency 31 observed for resorcinol at the same time. However, in the case of resorcinol a change in electrolyte 32 color was observed. We have revealed that the differentiating factor is the keto-enol tautomerism. 33 The NMR studies of resorcinol indicate the keto form in structure in presence of NaOH, while the 34 chemical structure of catechol does not change significantly in alkaline environment. 35
ASSESSMENT OF ROAD NETWORK PLANNING BY USING GIS-BASED MULTI-CRITERIA EVALUATION FOR CONVERSION OF COPPICE FOREST TO HIGH FOREST

Road network planning is fundamental for the forest areas appropriate to put into operation. And it is difficult to achieve the optimum goal in the total costs during the planning of road networks in particularly forest ecosystems through traditional methods, because variables of natural ecosystems (living and nonliving elements) have impacts at different degrees on road network plans. Fortunately, use of developed decision support systems (DSS) has capacity to gather and comparing with several decision variables, and that reveals impact degrees. In this study, multi-criteria evaluation (MCE) as DSS study were conducted in conversion of forests in coppice forests to high forests and reorganization of forest roads. Slope, aspect, road density, distance to road, land use and distance to mainstreams were used as criteria-decision variables to be used in forest road network planning. Determined degrees of decision variables were classified and clarified with fuzzy logic approach. The most cost-effective road routes were created along with calculated accumulative cost surface that is permeable layer for least-cost path analysis on this surface by combining the variables. Road network plan was created gradually by 3 different periods in coppice forest areas. Consequently, opening up rate with 3 period road network plan by using GIS that was determined as 67.22% and road density was calculated as 17.07m/ha. After, performing expert-controlled corrections on road network considering land to increasing opening-up activities of production forest rate and achieving optimum road density goal, opening up rate and road density were calculated as 70.22% and 20.12 m/ha, respectively. As a result, expert-controlled corrections were necessary to correct the possible errors that arising from the precisions and upgrades of the data used because of data quality and site-specific in reality.
Genome-Wide Profiling of PARP 1 Reveals an Interplay with Gene Regulatory Regions and DNA Methylation

Poly (ADP-ribose) polymerase-1 (PARP1) is a nuclear enzyme involved in DNA repair, chromatin remodeling and gene expression. PARP1 interactions with chromatin architectural multi-protein complexes (i.e. nucleosomes) alter chromatin structure resulting in changes in gene expression. Chromatin structure impacts gene regulatory processes including transcription, splicing, DNA repair, replication and recombination. It is important to delineate whether PARP1 randomly associates with nucleosomes or is present at specific nucleosome regions throughout the cell genome. We performed genome-wide association studies in breast cancer cell lines to address these questions. Our studies show that PARP1 associates with epigenetic regulatory elements genome-wide, such as active histone marks, CTCF and DNase hypersensitive sites. Additionally, the binding of PARP1 to chromatin genome-wide is mutually exclusive with DNA methylation pattern suggesting a functional interplay between PARP1 and DNAmethylation. Indeed, inhibition of PARylation results in genome-wide changes in DNA methylation patterns. Our results suggest that PARP1 controls the fidelity of gene transcription and marks actively transcribed gene regions by selectively binding to transcriptionally active chromatin. These studies provide a platform for developing our understanding of PARP1’s role in gene regulation.
MATCHABLE SUBGRAPH PROBLEM ON A BIPARTITE GRAPH

We consider the maximum weight perfectly matchable subgraph problem on a bipartite graph G = (UV, E) with respect to given nonnegative weights of its edges. We show that G has a perfect matching if and only if some vector indexed by the nodes in UV is a base of an extended polymatroid associated with a submodular function defined on the subsets of UV . The dual problem of the separation problem for the extended polymatroid is transformed to the special maximum flow problem on G. In this paper, we give a linear programming formulation for the maximum weight perfectly matchable subgraph problem and propose an O(n) algorithm to solve it.
Use of the Burch e Schneider cage and structural allografts in complex acetabular deficiency : 3-to 10-year follow up

http://dx.doi. org/10.1016/j.kjms. 201 1607-551X/Copyright a 2015, Kaohsiu Abstract This study aimed to evaluate retrospectively the clinical outcomes and complications of structural allografts and BurcheSchneider antiprotrusio cages to treat severe acetabular defects in revision total hip arthroplasty (THA). Between July 2003 and December 2010, 29 patients (representing 31 hips) underwent revision THA using structural allografts and Burch eSchneider cages for acetabular reconstruction. The patients had amean age of 59 years (range, 37e79 years). Seventeen hips had a Paprosky IIIA defect, 12 hips had a IIIB defect, and two hips had a pelvic discontinuity (PD) acetabular defect. After amean follow up of 5.5 years (range, 3.0 e10.5 years), all patients, except for two patients with recurrent infections, significantly improved, based on themeanHarris hip score (30 points vs. 67 points, p< 0.001) and theWestern Ontario and McMaster Universities Arthritis index (WOMAC) score (65 points vs. 32 points, p < 0.001). Using re-revision surgery as the endpoint, the cage had a survival rate of 76% [95%, confidence interval (CI), 67.4e84. 6%] at 5 years and 57% (95% CI, 39.3e74.7%) at 10 years. Other complications included hip dislocation [3 (9.7%) hips]; deep infection [3 (9.7%) hips]; and sciatic nerve impingement, vesicle-acetabular fistula, and leg lengthening [1 (3.2%) hip]. There was a trend toward a higher failure rate in hips with four revisions, compared to hips with three revisions or fewer (pZ 0.055). Three hips with a failed cage underwent re-revision surgery using a standard noncemented acetabular component. In conclusion, a structural allograft with Burch eSchneider antiprotrusio cage for complex acetabular defect is a technique-demanding procedure with a 5-year survival rate of 76%. Even with failed cage reconstruction, re-revision surgery with a noncemented acetabular component may be feasible once the allograft has healed. Copyright a 2015, Kaohsiung Medical University.

Chapter 1 Overview of Fish Immune System and Infectious Diseases

Cultured finfish are an important source of animal protein worldwide (Naylor et al. 2009), and the Food and Agriculture Organization (FAO) reported that over half of the world’s supply of fish and shellfish is now from aquaculture (FAO 2008). As fish consumption increases and natural fish stocks decrease, aquaculture practices will need to intensify in order to meet global demand. Intensification will likely lead to an increase in disease problems, due to a higher number of animals in a limited and confined environment and the influence of poor environmental conditions (i.e., water quality) on the fish immune system. For example, limited disease-related problems were reported in the channel catfish (Ictalurus punctatus) industry prior to 1980 because stocking densities were less than 10,000 fish/ha and maximum feeding allowances were about 50 kg/ha/day with most farms using a single crop system (Hawke and Khoo 2004). Production intensity increased following that time with >12,000 fish/ha stocked, and feeding increased accordingly to 90–112 kg/ha/day. Multi-cropping systems (i.e., various sizes of fish cultured together) that utilized limited water exchange were also employed
Emigrants ’ remittances and economic growth in small transition economies : The cases of Moldova and Albania

The breakdown of the socialist system and the following collapse of the Balkan and Eastern European economies led to large-scale emigration outflows. These flows in turn, led to massive inflows of remittances to the emigration transition economies. Remittances are considered to be the basic gain of migration for the emigration countries and their main compensation for losing (temporarily or more permanently) a part of their labor force. Whether remittances contribute to the economic development and growth of the country receiving them depends on the way they are used, that is what activities they finance. There are examples of countries that use them for productive investment which is considered more development-stimulating than consumption or imports. This paper investigates the macroeconomic effects of remittances in two small, transition emigration countries namely Moldova and Albania. The econometric investigation, based on time series analysis and Keynesian macroeconomic modeling, examines the impact of remittances on three key macroeconomic variables of these economies: consumption, imports and investment, in order to assess the use of the growth potential of remittances.
Gender Differences and Political Deliberations on Social Media

Social media has emerged as an arena for political deliberation. Facebook, Twitter, and WhatsApp are major platforms where political debates/deliberation take place. This study was undertaken to investigate if attitude and perception towards these online platforms for political deliberation differs for male and female. For this purpose, a quantitative study was conducted using a structured questionnaire among 400 students of a private university. The finding suggests that males are more likely to be involved on political deliberation on social media than their female counterparts. Also male students value social media as an arena for political deliberation more than their female students.

Departament d’Ecologia, Universitat de Barcelona, Av. Diagonal 645, Barcelona 08028, Spain A space-for-time substitution approach was used to evaluate potential effects of climate change on stream nutrient uptake by examining the relationship between stream environmental parameters and carbon (C), nitrogen (N) and phosphorus (P) uptake along an altitudinal gradient. The study was carried out in 14 streams located in the Central Pyrenees (NE Spain) draining calcareous catchments that cover an altitudinal range of 700–2,100ma.s. l. In these streams, uptake of inorganic (soluble reactive phosphorus (SRP), ammonium and nitrate) and organic (acetate and glycine) nutrients was estimated. Additionally, several physical, chemical and biological parameters were measured. Results showed higher uptake for both SRP, a potentially limiting nutrient in these streams, and glycine, a labile source of dissolved organic N, than for the rest of the nutrients. Uptake of SRP, nitrate, glycine and acetate varied along stream environmental gradients associated with changes in stream hydromorphology, SRP availability and epilithic biomass. However, these gradients did not vary with altitude. These results indicate that climate change effects on stream nutrient uptake are more likely to be driven by indirect effects on hydromorphology and nutrient availability induced by shifts in the precipitation and run-off regime than by direct modifications in the thermal regime.
Working creatively with young children within a context of continuous trauma

In September 2001, Ardoyne (North Belfast) Northern Ireland drew international media attention,duetoadisputecentredonstudents andparents, andtheir routetotheHolyCross School. Both parents and children experienced verbal and physical abuse from protesters on their way to school on a daily basis. The Holy Cross School is located in anareathat has hadthe secondhighestdeath toll relatedtoarmedcon£ict inNorthern Ireland (Fay, Morrisey, & Smith, 1997). This is also an area with high levels of social deprivation, and therefore, physical and mental health is also poor.There exists an on-going, intense con£ictbetweenparamilitarygroups of opposing political allegiance. The elements of this con£ict include rioting, pipe bombs, car crime, intimidation of families andtorture(socalled‘punishmentbeatings’). The school quickly recognized the fear and terror the children and parents experienced, and mobilized support, within the community and beyond, for the families. Holy Cross School is an all girls primary school, so National Organisation forVictims Assistance (NOVA) was asked to support the 4and 5-year-old girls.We decided to use a group format as primarily this was a community experience, and there were broad similarities in reactions. Group work would also facilitate rebuilding of trust, counteract isolation and engage the community strengths and resources. Two practitioners from NOVA facilitated two groups of ¢ve girls for eight weekly sessions. Thegirlspresentedavarietyof somatic,mood and behavioural responses. These included sleep di⁄culties, angry outbursts, wetting (dayandnight), askingquestions, beingmore clingy or more withdrawn, poor concentration,feelingsadandnotplayingverymuch. These responses are similar to those reported in the literature on the reactions of children to a threatening external event (Eth & Pynoos, 1984; Monahon, 1993; Pynoos, Steinberg, & Goenjian,1996; Lanyado,1999; Perry,2000; Shalev&Ursano,2002).
Acoustical approach to analysis of energy conversions in an oscillating bubble

Acoustic radiation of freely oscillating bubbles has been studied experimentally. The oscillating bubbles have been generated by underwater spark discharges. Recorded pressure waves made it possible to determine the acoustic energy radiated by the oscillating bubbles and potential energy of the bubbles when attaining the first and second maximum volumes. Comparison of the potential and acoustic energies revealed that about 70 % of the potential energy of the bubble available at the first maximum volume has been converted into an unidentified energy. A possible candidate for the yet unknown energy conversion mechanism seems to be vapor condensation and evaporation, converging shock wave in the bubble interior and turbulence in the liquid when the bubble compression and expansion are not symmetric. The measured energies are compared with energies computed using a suitable theoretical model. These comparisons also show that the present theoretical models do not encompass all energy conversions.
