Narrowband interference mitigation in UWB communication with energy detector

Ultra wideband (UWB) is a reliable candidate for supporting a physical layer in Body Area Networks (BAN) and because of their wideband, UWB systems can have their performance degraded due to the interference from narrowband transmission. Methods must be developed to protect UWB systems that are exposed to this negative impact of the narrowband interference (NBI). Most proposed solutions have been developed for coherent and transmitted-reference receivers but a very few of these principles are eligible with the noncoherent energy detector (ED) receiver. The work presented thereafter aims at proposing a novel method to identify and mitigate the narrowband interference in ultra wideband transmissions. We use an efficient algorithm with a modified but still simple energy detector, and the performance of the method is evaluated by means of computer simulations.
Enhanced method for voltage range controlled OLTC-equipped distribution transformers

Increasing load and the growing proportion of injected power from distributed energy generation lead to higher loading of distribution grids. Without suitable improvements like e. g. additional cables or substations, violations of voltage constraints in low voltage distribution grids have to be expected. A further alternative is represented by on-load tap-changers (OLTC) which are combined with distribution transformers. This paper presents an enhanced method for controlling them using a voltage range as input parameter. The voltage drop or rise between the substation and the first nodes of the strings is taken into account as it can be determined with little effort. This enables the consideration of similar loading in the strings of a distribution grid. The results of the simulations prove the advantages compared to the underlying approach. The improved method features less switching operations which leads to less wear and accordingly to lower maintenance effort.
Tax Evasion and Financial Instability

Purpose The purpose of this paper is to explore the association between tax evasion and financial instability. The discussion also examines the effects of tax evasion for financial instability. Design/methodology/approach This paper is an exploratory study on the effect of tax evasion on financial instability Findings The paper shows that tax evasion can reduce the tax revenue available to governments to manage the economy and can weaken the government’s ability to promote stability in financial systems, whereas on the contrary, taxpayers who evade taxes feel they can use the evaded tax money to rather improve their own financial stability. Originality/value This paper presents the first attempt to carefully examine the association between tax evasion and financial instability.
Use of Bioluminescence Markers To Detect Pseudomonas spp. in the Rhizosphere

The use of bioluminescence as a sensitive marker for detection of Pseudomonas spp. in the rhizosphere was investigated. Continuous expression of the luxCDABE genes, required for bioluminescence, was not detectable in the rhizosphere. However, when either a naphthalene-inducible luxCDABE construct or a constitutive luxAB construct (coding only for the luciferase) was introduced into the Pseudomonas cells, light emission could be initiated just prior to measurement by the addition of naphthalene or the substrate for luciferase, n-decyl aldehyde, respectively. These Pseudomonas cells could successfully be detected in the rhizosphere by using autophotography or optical fiber light measurement techniques. Detection required the presence of 103 to 104 CFU/cm of root, showing that the bioluminescence technique is at least 1,000-fold more sensitive than β-galactosidase-based systems.
Restoration strategy in a self-healing distribution network with DG and flexible loads

This paper develops an algorithm for energy management of a distribution network considering a restorative plan for most possible devastating contingencies in the network. The distribution network is self-healing and consists of smart meters and remotely controlled automated switches. Distributed energy resources and flexible loads provide the redundant capacity for restoration. Under normal operating conditions, the objective of the energy management system is to minimize the generation cost, while under emergency conditions, the objective is to minimize the amount of shed load, giving priority to critical loads. The energy management problem forms a non-linear programming problem. Simulation results verify the effectiveness of the proposed algorithm in energy management and restoration of a distribution network.
La relación causal entre la mente y el cuerpo. Searle y el naturalismo biológico

El problema de la relación causal entre el cuerpo y la mente parece merecer, por su importancia y el tiempo a él dedicado, un capítulo aparte en la teoría del conocimiento, en la filosofía de la mente y en las ciencias cognitivas. El dualismo cuerpo-mente dificulta enormemente la explicación teórica de un nexo causal entre uno y otro, problema central en la filosofía de Descartes, mas fácilmente rastreable en autores anteriores como San Agustín o Platón. En el presente trabajo analizaremos el desarrollo efectuado por John Searle con el fin de superar este problema mediante una reformulación teórica de los conceptos involucrados en su descripción y conceptuación. Su tratamiento se basa en el reemplazo del concepto tradicional de causalidad por uno más complejo, mediante la introducción teórica de diferentes niveles de observación y del concepto de realización, integrante de este nuevo concepto de causalidad.
A facile method to transfer vertical aligned graphene film/polydimethylsiloxane composite to thermal interface materials

In this work, a novel and facile fabrication method of graphene-based composites is presented, which is a good candidate for thermal interface materials in advanced packing. By rolling the graphite films and infiltrating PDMS precursor, a vertically aligned-graphene/PDMS (VaG/PDMS) composite was gained with high thermal conductivity of 5.349 W·m-1K-1 and excellent thermostability. The enhancement of the thermal conductive performance is due to the vertical alignment of graphite films, which provides a rapid and effective heat transfer pathway. Furthermore, theoretical prediction and finite element calculation were carried out to reveal the mechanisms of high thermal conductivity controlled by alignment of graphite film.
Cartilage repair of experimentally 11 induced osteochondral defects in New Zealand White rabbits

Articular cartilage has a limited capacity for self-repair in adult humans, and methods used to stimulate regeneration often result in re-growth of fibrous cartilage, which has lower durability. No current treatment option can provide complete repair. The possibility of growth factor delivery into the joint for cartilage regeneration after injury would be an attractive treatment option. A full thickness osteochondral defect of 4 mm in diameter and 2 mm deep was created by mechanical drilling in the medial femoral condyle in 20 female adult New Zealand White rabbits. In an attempt to improve regeneration a hyaluronic hydrogel system, with or without bone morphogenetic protein-2 (BMP-2) was delivered intraarticularly. The contralateral joint defect was treated with saline as control. Throughout the study, rabbits were clinically examined and after 12 (n = 6) or 24 (n = 9) weeks, the rabbits were euthanized and the joints evaluated by histology. The defects healed with fibrocartilage like tissue, and the filling of the defects ranged from less than 25% to complete. The healing of the defects varied both inter- and intra-group wise. Treatment with hyaluronan gel with or without BMP-2 had no effect on cartilage regeneration compared with controls. Instead, severe ectopic bone formation was found in seven joints treated with BMP-2. In conclusion, the present study shows that neither treatment with hyaluronic gel alone, nor in combination with BMP-2, improves the healing of an induced cartilage defect in rabbits. It further shows that BMP-2 can induce ectopic bone formation, which severely affects the functionality of the joint.
MmWave channel estimation via atomic norm minimization for multi-user hybrid precoding

To perform multi-user multiple-input and multipleoutput transmission in millimeter-wave (mmWave) cellular systems, the high-dimensional channels need to be estimated for designing the multi-user precoder. Conventional grid-based Compressed Sensing (CS) methods for mmWave channel estimation suffer from the basis mismatch problem, which prevents accurate channel reconstruction and degrades the precoding performance. This paper formulates mmWave channel estimation as an Atomic Norm Minimization (ANM) problem. In contrast to grid-based CS methods which use discrete dictionaries, ANM uses a continuous dictionary for representing the mmWave channel. We consider a continuous dictionary based on sub-sampling in the antenna domain via a small number of radio frequency chains. We show that mmWave channel estimation using ANM can be formulated as a Semidefinite Programming (SDP) problem, and the channel can be accurately estimated via off-the-shelf SDP solvers in polynomial time. Simulation results indicate that ANM can achieve much better estimation accuracy compared to grid-based CS, and significantly improves the spectral efficiency provided by multi-user precoding.
Life-Cycle Variation in the Association between Current and Lifetime Earnings

Researchers in a variety of important economic literatures have assumed that current income variables as proxies for lifetime income variables follow the textbook errors-in-variables model. In an analysis of Social Security records containing nearly career-long earnings histories for the Health and Retirement Study sample, we find that the relationship between current and lifetime earnings departs substantially from the textbook model in ways that vary systematically over the life cycle. Our results can enable more appropriate analysis of and correction for errors-in-variables bias in a wide range of research that uses current earnings to proxy for lifetime earnings.
Reducing Reconfiguration Overheads in Heterogeneous Multicore RSoCs with Predictive Configuration Management

a predictive dynamic reconfiguration management service is described here, targeting a new generation of multicore SoC that embed multiple heterogeneous reconfigurable cores. The main goal of the service is to hide the reconfiguration overheads, thus permitting more dynamicity for reconfiguring. We describe the implementation of the reconfiguration service managing three heterogeneous cores; functional results are presented on generated multithreaded applications.
Emergency Transcallosal Resection of Hypothalamic Hamartoma for “Status Gelasticus”

Summary: Hypothalamic hamartomas are rare developmental malformations of the inferior hypothalamus. Typically they result in symptomatic, refractory mixed seizure disorder with trademark gelastic or laughing seizures. We present a 30‐month‐old boy with a hypothalamic hamartoma and a nearly 2‐month history of near‐continuous gelastic seizures, which we have labeled “status gelasticus. ” The seizures were refractory to multiple antiepileptic drugs (AEDs), and emergency transcallosal resection of the hypothalamic hamartoma was performed with resultant near‐immediate cessation of the seizures. At 12‐month follow‐up, the patient was averaging one brief gelastic seizure every 2 weeks, with a longest seizure‐free period of 2 months.
Evaluating the Evidence for Choosing WiselyTM in Primary Care Using the Strength of Recommendation Taxonomy (SORT)

Objective: The goal of this study was to evaluate the quality of evidence supporting primary care–relevant Choosing WiselyTM recommendations using the Strength of Recommendation Taxonomy (SORT). Methods: All Choosing Wisely “top 5” lists published by American medical specialty societies through June 2014 were reviewed for relevance to primary care. Both authors independently applied SORT to generate an evidence letter grade for each of the included recommendations, relying on citations supplied by the nominating organizations. Results: Of 310 recommendations, 224 were identified as being relevant to primary care. We rated 43 (19%) as SORT level of evidence A, 57 (25%) as B, and 124 (55%) as C. Conclusion: We found that a majority of primary care–relevant Choosing Wisely recommendations are based on expert consensus or disease-oriented evidence. Further research is warranted to strengthen the evidence base supporting these recommendations in order to improve their acceptance and implementation into primary care.
French Retailers and Sustainable Development

Abstract This chapter focuses on French food retailers and sustainable development. The food retailing groups can be divided into three types of distributors: integrated groups (Carrefour, Casino, Auchan, and Cora), groups of independent stores (Leclerc, Intermarche, and System U), and hard discounters as (Lidl and Aldi). In addition, in the sphere of more sustainable distribution, there are also specialized retailers such as Biocoop, Naturalia, La Vie Claire, and direct channels. These channels offer an alternative to the dominant model of industrialized and standardized agriculture and supply symbolized by mass distribution. The evolution of the discourse on sustainable development from 2005 to strategies proposing local products, bio products, and private labels shows that mass retailers have understood that taking into account the collective interest of society can be a source of significant differentiation in a fiercely competitive market. A supplementary finding of this chapter is the major strategic role of private labels in the implementation of retailers’ sustainable development policy: improving products, rethinking packaging policy, and formulating advice for consumers.
Small Banks Compositional Strategic TransformationFramework and Implementation Measures Composition-BasedView

In view of the status quo of small banks in China, the study put forward a strategic transformation framework for them based on the perspective of Composition-based View which provides a new strategic transformation path. Moreover, the appropriate measures that proposed for the implementation of small banks in transition provide a new way of thinking. Entrepreneur ability and collaboration-oriented are internal drivers of banks to implement the strategy while availability of external resources and customer demand areexternal drivers. According to the framework of the compositional strategic transformation, compositional strategy can be implemented by banks via compositional-offering and compositional-competition.

100 μW Coreless Flyback Converter for Microbial Fuel Cells Energy Harvesting

The microbial fuel cells (MFCs) are emerging energy harvesters that are promising for the autonomous supply of seafloors remote sensors. Regarding the low voltage and power level delivered by MFC an electrical interface is required to condition the sensors needs. The flyback in discontinuous conduction mode appears to be the best candidate to extract the maximum power delivered by the MFC, to electrically isolate the sensor from the source and to boost the voltage to the one required by the energy buffering. Our work highlighted the significant impact of the magnetic core loss of coupled inductances on the power efficiency decrease, mainly due to the hysteresis and magnetic saturation even at µ-scale energy transfer. In this paper, we propose to remove the magnetic core to suppress these previously mentioned losses. The low density harvested power (100 µW for 10th cm² electrodes) and low-size constraint i.e. m2-scale in seafloors remote sensors application allow to use 0.5 m2 air-core inductance. By plugging a 20-cm2 MFC delivering a maximum power of 90 µW at 0.3 V, the proposed air-core based flyback achieved 60% efficiency experimentally. This figure correctly matches simulations in which a model of the coreless coupled inductances, extracted from experimental characterizations, is used. This work is the first to validate the concept of a flyback with coreless coupled inductances harvesting 10th of µWs.
New insights into the mechanisms of vitamin D action

The biologically active metabolite of vitamin D, 1,25‐dihydroxyvitamin D3 (1,25(OH)2D3) is a secosteroid whose genomic mechanism of action is similar to that of other steroid hormones and is mediated by stereospecific interaction of 1,25(OH)2D3 with the vitamin D receptor (VDR) which heterodimerizes with the retinoid X receptor (RXR). After interaction with the vitamin D response element (VDRE) in the promoter of target genes, transcription proceeds through the interaction of VDR with coactivators and with the transcription machinery. The identification of the steps involved in this process has been a major focus of recent research in the field. However, the functional significance of target proteins as well as the functional significance of proteins involved in the transport and metabolism of vitamin D is also of major importance. Within the past few years much new information has been obtained from studies using knockout and transgenic mice. New insight has been obtained using this technology related to the physiological significance of the vitamin D binding protein (DBP), used to transport vitamin D metabolites, as well as the physiological significance of target proteins including 25‐hydroxyvitamin D3 24‐hydroxylase (24(OH)ase), 25‐hydroxyvitamin D3‐1α‐hydroxylase (1α‐(OH)ase), VDR, and osteopontin. The crystal structure of the DBP and the ligand binding domain of the VDR have recently been reported, explaining, in part, the unique properties of these proteins. In addition novel 1,25(OH)2D3 target genes have been identified including the epithelial calcium channel, present in the proximal intestine and in the distal nephron. Thus in recent years a number of exciting discoveries have been made that have enhanced our understanding of mechanisms involved in the pleiotropic actions of 1,25(OH)2D3. © 2002 Wiley‐Liss, Inc.
Aging Increases Neuronal Nitric Oxide Release and Superoxide Anion Generation in Mesenteric Arteries from Spontaneously Hypertensive Rats

We hypothesized that neuronal NO release as well as its bioavailability and vasomotor response could be affected when aging and hypertension are present simultaneously. The neuronal nitric oxide (NO) release, its metabolism and vasomotor response induced by electrical field stimulation was analyzed in isolated segments of endothelium-denuded mesenteric arteries from young and old spontaneously hypertensive rats (SHR). The nitric oxide synthase (NOS) inhibitor NG-nitro-arginine-methyl ester (L-NAME) and NOS inhibitor 7-nitroindazole both strengthened electrical field stimulation-elicited contractions more in arteries from young than aged SHR rats. Superoxide dismutase (SOD) potentiated the L-NAME effect in segments from old rats, whereas catalase decreased the contractions induced by electrical field stimulation and noradrenaline but did not modify the L-NAME effect. In noradrenaline-precontracted segments, sodium nitroprusside induced a similar relaxation in arteries from both experimental groups. This relaxation was increased by SOD in old SHR. 8Br cGMP induced greater relaxation in segments from old than from young SHR. Electrical field stimulation induced a tritium release in arteries preincubated with [3H]-noradrenaline, that was similar in both young and old SHR rats. Electrical field stimulation induced NO2– formation, which was greater in segments from old than young SHR rats. Basal cGMP levels and those stimulated with sodium nitroprusside were similar in segments from both groups. Superoxide anion production was greater from old than young SHR rats. Peroxynitrite production induced by electrical field stimulation was only detected in segments from old SHR. The results obtained in mesenteric arteries from old SHR showed increased neuronal NO release and superoxide anion production with respect to those observed in arteries from young SHR rats. This induced decreased NO bioavailability through peroxynitrite formation. The final effect is to decrease the involvement of neuronal NO in electrical field stimulation-induced vasomotor response in arteries from old SHR rats.
Exact, Nonparametric Inference When Doses Are Measured With Random Errors

Studies that estimate the effects of exposure to a possibly harmful agent often compare exposed subjects who received varied doses with matched controls who received zero dose. If the doses are measured with error, then one may wish to use the fallible doses to estimate a linear relationship between the unobserved true dose and the observed response. If one is willing to assume that the dose errors for exposed subjects are symmetrically distributed about 0—that is, the dose errors are pure errors and not, say, systematic underreporting of exposure—then the presence of zero-dose controls is all that is needed to obtain exact, distribution-free confidence intervals and tests, and consistent point estimates. The method is simpler for matched pairs than for matched sets with two or more matched subjects, and it is illustrated using two studies, one of each kind. With matched pairs, as in this first example, the method uses Wilcoxon's signed rank test as the basis for inference. When there are several zero-dose controls matched to each exposed subject, the familiar null distribution of the signed rank statistic is no longer applicable because of dependence within matched sets, so the appropriate exact distribution and large-sample approximation are developed.
Usage de la modélisation multi-vue d'entreprise pour la conduite des systèmes de production

La re-ingenierie du systeme de production et des produits est une activite permanente de l'entreprise, et en constitue en quelques sorte le pilotage organisationnel. Le besoin en methodologie est dasn ce domaine tres important, et constitue le sujet de ce travail. Dans un premiers temps, nous eclaircissons l'usage qui peut etre fait des modeles pour structurer la demarche d'ingenierie, et cherchons ainsi a promouvoir la modelisation d'entreprise comme outil de raisonnement de pre-evaluation et de documentation des systemes de production. Dans un second temps, nous situons la demarche d'ingenierie produit / systeme comme une acitvite recurrente participant a l'evolution de l'entreprise en tant que niveau de pilotage venant, par une logique de projets ou par une amelioration continue, moduler la structure et l'organisation du systeme physique.
