PFC Converter with Improved Input Current Zero-crossing Distortion

Abstract In this study, a voltage superposition concept is used without phase adjustment of the input current command and without enlarging the turn-on period of the switch in the vicinity of the zero input voltage, but only with a few components added to the PFC converter, so as to improve the zero-crossing distortion of the input current, thereby further reducing the total harmonic distortion. Eventually, the mathematical deductions and experimental results are provided to verify the effectiveness of the proposed circuit.

The Cloning Attack Vulnerability in WSN Key Management Schemes

—The majority of existing key management schemes in wireless sensors networks suffer from the physically compromised of nodes. This vulnerability allows an adversary to reproduce clones from a compromised node and to inject them into several locations on the network to conduct other types of attacks. Moreover, the joining of new nodes to the network (for maintenance), which is an inevitable step to prolong its life or to correct voids, presents the best opportunity to conduct such an attack. In this paper, we review several key management schemes and we highlight their weakness regarding the cloning attack.
Slr1293 in Synechocystis sp. Strain PCC 6803 Is the C-3 (cid:2) ,4 (cid:2) Desaturase (CrtD) Involved in Myxoxanthophyll Biosynthesis

When grown at high light intensity, more than a quarter of the total carotenoids in the unicellular cyanobacterium Synechocystis consists of myxoxanthophyll, a polar carotenoid glycoside. The biosynthetic pathway of myxoxanthophyll is unknown but is presumed to involve a number of enzymes, including a C-3 (cid:1) ,4 (cid:1) desaturase required to add one double bond to generate 11 conjugated double bonds in the monocyclic myxoxanthophyll. A candidate for this desaturase is Slr1293, which was identiﬁed by genome similarity searching. To determine whether Slr1293 is a desaturase recognizing neurosporene and lycopene, slr1293 was expressed in Escherichia coli strains accumulating neurosporene or lycopene. Conﬁrming such a desaturase function for Slr1293, these E. coli strains accumulated 3 (cid:1) ,4 (cid:1) -didehydroneurosporene and 3 (cid:1) ,4 (cid:1) -didehydrolyco-pene, respectively. Indeed, deletion of slr1293 in Synechocystis provides further evidence that Slr1293 is a desaturase recognizing neurosporene:
STEADY-STATE GI / GI /n QUEUE IN THE HALFIN–WHITT REGIME

We consider the FCFS GI / GI /n queue in the so-called Halﬁn–Whitt heavy trafﬁc regime. We prove that under minor technical conditions the associated sequence of steady-state queue length distributions, normalized by n 1 / 2 , is tight. We derive an upper bound on the large deviation exponent of the limiting steady-state queue length matching that conjectured by Gamarnik and Momcilovic [ Adv. in Appl. Probab. 40 (2008) 548–577]. We also prove a matching lower bound when the arrival process is Poisson. Our main proof technique is the derivation of new and simple bounds for the FCFS GI / GI /n queue. Our bounds are of a structural nature, hold for all n and all times t ≥ 0, and have intuitive closed-form representations as the suprema of certain natural processes which converge weakly to Gaussian processes. We further illustrate the utility of this methodology by deriving the ﬁrst nontrivial bounds for the weak limit process studied in [ Ann. Appl. Probab. 19 (2009) 2211–2269].
Anomalies in the Inﬂuenza Virus Genome Database: New Biology or Laboratory Errors? (cid:1) †

A search of the inﬂuenza virus genome database reveals anomalies associated with a nonnegligible number of submitted sequences. There are many pairs of viral segments that are very close to each other in nucleotide sequence but relatively far apart in reported time of isolation, resulting in an abnormally low evolutionary rate. Also, some sequences show clear evidence of apparent homologous recombination, a process normally assumed to be extremely rare or nonexistent in this virus. These ﬁndings may point to surprising new biology but are perhaps more readily explained by stock contamination or other errors in the sequencing laboratories. the years, an extraordinary amount of inﬂuenza genomic been submitted databases and For instance, there are now over 3,300 full genome sets in the NCBI’s rapidly growing Inﬂuenza Virus Resource. To our knowledge, no systematic attempt has been made to assess the quality of sequence data in this and similar collections. Our observations show that a fraction of the sequences in the database exhibit anomalous properties that point to either radically new biology or, more likely, problems with the data. As a ﬁrst example, we consider the rate of nucleotide substitution in the inﬂuenza A virus. This rate has been previously estimated at 0.001 to 0.007
Reconstruction of f-essence and fermionic Chaplygin gas models of dark energy

Recently, it was proposed a new fermionic model of dark energy, the so-called f-essence. In this work, we explicitly reconstruct the different f-essence models. In particular, these models include the fermionic Chaplygin gas and the fermionic generalized Chaplygin gas models of dark energy. We also derive the equation of state parameter of the selected f-essence models.
Interferon type I response in porcine reproductive and respiratory Interferon type I response in porcine reproductive and respiratory syndrome virus-infected U.S. Meat Animal Research Center-145 syndrome virus-infected U.S. Meat Animal Research Center-145 cells cells

Summary. Infection by porcine reproductive and respiratory syndrome virus (PRRSV) results in a weak induction of the innate immune response. There are many genes that collectively comprise this response and the extent to which each gene responds to PRRSV infection is unclear and warrants further investigation. To this end, we have utilized real-time PCR using SYBR Green I dye-based detection to quantify transcript abundance of the type I interferons (IFN- α and - β ) and IFN- β transcriptional enhanceasome genes. In MARC-145 cells, both IFN-α and - β transcript abundance were unaffected by PRRSV infection. However, stimulation of MARC-145 cells by exogenous double-stranded RNA, resulted in signiﬁcant increases in transcript abundance of both IFN- α and - β as well as IFN- β enhanceasome components, indicating that a type I IFN response could be induced in these cells. The double-stranded RNA induction of type I IFN transcription was signiﬁcantly inhibited by dual-exposure with PRRSV. These results suggest that PRRSV infection directly interferes with type I IFN transcriptional activation early in its pathway, at the level of IFN- β gene transcription.
Proteases Involved in Generation of I- and a-Amylases from a Large Amylase Precursor in Bacillus polymyxa

The genes for extracellular neutral protease (Npr) and intracelular serine protease (Isp) were cloned from Bacillus polymyxa in order to elucidate the process involved in the generation of multiple ,B-amylases and an a-amylase from a large amylase precursor. The npr gene was composed of 1,770 bp and 570 amino acids, while the isp gene was composed of 978 bp and 326 amino acids. Both proteases produced by E. coli cleaved the amylase precursor to generate I- and a-amylases. Furthermore, several other proteases produced the same products from the precursor. A 130-kDa amylase precursor has two large domain structures responsible for the generation of (3- and a-amylases. The junction region of approximately 200 amino acids may be exposed on the surface of the molecule and susceptible to proteolytic enzymes, which results in the formation of multiple amylases.
Fresh and Frozen Food Box/Lockers as part of Market, e-Market and Collaborative Economy Smart City Environment

In the Smart City environment several distribution modes are proposed, ranging from physical & virtual shopping to goods transportation and distribution. Use of the classical B2C schema can be upgraded to that of the B2B2C one and its variations. We study the use of a new approach based on lockers supporting fresh and frozen food storage, together with a new distribution system able to take collaborative economy into account. This allows these lockers to be used by several providers, thereby shortening distribution circuits. We describe and discuss a systemic and logistic point of view.
Simulation of Lane Switching in Self-Driving Automobiles using GTA-V

The key significance of a self-driving automobile is it is a mechanical contraption that can progress between objectives without human maneuvers, sounds exceptionally essential and clear yet, honestly, this scarcely covers the surface. For a self-driving automobile to come to affirmation, we require both gear fragments and programming packs that we compose and construct congruous with each other. In this paper, we exhibit the item points of view vital to producing a model that can make sense of how to drive an automobile in a to a great degree diverse plan of a virtual condition. To content with the software aspects of a self-driving vehicle, we make use of Convolutional Neural Networks (CNN) that works on the idea of regression at its crux. We further discuss the information outlines which shape the foundations of the proposed procedure. The process involves screen capturing by employing OpenCV while physically driving a vehicle in a PC amusement, GTA-V.

. Uncoupled GPS Road Constrained Positioning based on Constrained Kalman Filtering. In 13th International Symposium on Wireless Personal Multimedia Communications (WPMC 2010): Oct 11, 2010 -

Car navigation systems take advantage of the synergies between the Global Positioning System (GPS) and digital road maps. For this kind of applications the digital road maps can provide a priori information to improve the positioning accuracy. This paper presents a method for the estimation of the user’s position, based on GPS positioning estimates, constrained to a road map. A low-cost GPS receiver was assumed as being the source of the positioning information. The techniques used in the proposed estimator were developed taking in consideration that the platforms where typically they would be implemented are characterized by having reduced computational capabilities. The algorithm’s positioning accuracy was characterized based on real data from a low-cost GPS receiver installed in a car. Different scenarios were used in the field trials in order to evaluate the impact of the satellite constellation visibility and geometry in the algorithm’s performance.
Hepatorenal Syndrome, Are we making any Progress? Castillo International Journal of Hepatology & Gastroenterology

be underestimated [5,6]. Factors that may overestimate renal function include: medications, fl uctuations in serum creatinine in patients with cirrhosis, increased volume of distribution and elevated bilirubin [14,15]. ABSTRACT Hepatorenal Syndrome (HRS) poses a unique challenge to liver failure patients. The key pathophysiologic feature of HRS includes a marked reduction in renal blood ﬂ ow that is caused by intense vasoconstriction of the renal circulation counteracting the pathologic systemic and splanchnic arterial vasodilation. The diagnosis of HRS requires a reduction in the glomerular ﬁ ltration rate and exclusion of other causes of renal failure. Novel biomarkers including cystatin C, neutrophil gelatinase associated lipocalin (NGAL), IL-8 and liver-type fatty acid binding protein (L-FABP) have been proven to be useful for predicting HRS. All existing treatments can only be considered supportive. Other potential therapeutic options such as selectively targeting renal vasodilation are promising. Currently, liver transplant is the only treatment that improves long-term survival.

An Evolutionary Justiﬁcation of the Emergence of Leadership Using Mathematical Models

: The value and importance of leadership is evident by its prevalence throughout human societies and organizations. Based on an evolutionary argument, models are presented here that provide a mathematical justiﬁcation as to how and why leadership arose in the ﬁrst place and then persisted. In this setting, by a leader is meant a person whose overall actions are ultimately responsible for the well-being and survival of the group. The proposed models contain parameters whose values reﬂect group size, harshness of the environment, diversity of actions taken by individuals, and the amount of group cohesion. Mathematical analysis and computer simulations are used to identify conditions on these parameters under which leadership results in an increased survival probability for the community.
Coupling chemosensory array formation and localization made this article openly available. Please share how this access benefits you. Your story matters

Chemotaxis proteins organize into large, highly ordered, chemotactic signaling arrays, which in Vibrio species are found at the cell pole. Proper localization of signaling arrays is mediated by ParP, which tethers arrays to a cell pole anchor, ParC. Here we show that ParP’s C-terminus integrates into the core-unit of signaling arrays through interactions with MCP-proteins and CheA. Its intercalation within core-units stimulates array formation, whereas its N-terminal interaction domain enables polar recruitment of arrays and facilitates its own polar localization. Linkage of these domains within ParP couples array formation and localization and results in controlled array positioning at the cell pole. Notably, ParP’s integration into arrays modifies its own and ParC’s subcellular localization dynamics, promoting their polar retention. ParP serves as a critical nexus that regulates the localization dynamics of its network constituents and drives the localized assembly and stability of the chemotactic machinery, resulting in proper cell pole development. DOI: revealed that ParP interacts with other proteins in the chemotaxis arrays. enables ParP to the the the the was amplified using primers ShDo-Spc-CFP-CheW and CFP-VC2059-ccw from plasmid pAA75. The resulting fragment was digested with HincII and SphI and inserted into the corresponding sites of plasmids pPM15, pSR1102, pPM14 and pAK105, resulting in plasmids pAA76, pAA77, pAA78 and pAA79, respectively.
Tumor Promoter or Tumor Suppressor: A Question for Epigenetic Regulatory Factors

Epigenetics is defined as the gene expression alterations, properly leading to a phenotype change, without DNA sequence alteration [1]. In cancer, epigenetic alterations are changes in DNA and histone modifications, which cause promoting oncogenic genes and suppressing tumor suppressor genes, as well as other cell homeostasis events leading to a normal cells becoming tumorigenic. The deregulation of epigenetic modifications or epigenetic regulatory factors plays an important role in cancer initiation and progression. However, functions of many epigenetic regulatory factors are complex on tumorigenesis, sometimes showing opposite roles in different cancers.
Greenﬁeld FDI and Skill Upgrading (cid:3)

Globalisation is one of the primary accused culprits of growing income inequality in the developed world. In particular, outbound foreign direct investment (FDI) is often associated with general “skill upgrading" in the home country, that is, a shift in relative labour demand from low skilled workers towards more skilled workers. Nevertheless, the empirical evidence indicates that such effects are small at best, especially in contrast to those for overall trade in intermediates (which includes both intra-ﬁrm trade and foreign outsourcing). In response, we utilise a proprietary dataset on greenﬁeld FDI. In contrast to M&A FDI, which can represent acquisition of new technologies or elimination of competitors, greenﬁeld FDI may be more closely linked to skill upgrading, especially when its done to take advantage of international differences in factor prices. Given that our data delineate FDI by function as well as by destination country, we are able to capture the different motives of FDI and to account for the fact that different functions in different countries may substitute for different skill levels at home. Using these data in conjunction with industry-level data on seventeen developed home countries, we ﬁnd that greenﬁeld FDI results in polarised skill upgrading, i.e. an increase in the relative share of employment and compensation of the most skilled workers to the detriment of the medium skilled workers. This impact is strongest for support services (e.g. call centres), knowledge services (e.g. R&D), and retail FDI with little indication of an impact from FDI in other functions. Our estimates suggest that the change in the high skilled compensation share explained by support services is of the same order of magnitude as what is found in other studies for trade in services. Unlike those studies, however, we ﬁnd that demand for medium skilled workers falls from outbound FDI whereas that of the lowest skilled workers remains unchanged. Thus, in contrast to overall trade in services where globalisation leads to increased income inequality between the lowest skilled workers and other groups, increased outbound FDI leads to an increased gap between the most skilled and the moderately skilled workers. FDI then has parallels to the results from the labour literature estimating the non-monotonic impacts on the demand for skills of computerisation and service offshoring.
Impact of Women’s Body Mass Index (BMI) on the Outcomes of Intra-Cytoplasmic Sperms Injection (ICSI)

: Obesity is one of major health problems across the world that negatively impact many body systems and organs including reproductive system. The objective of this study was to examine the effect of body-mass index (BMI) on the outcomes of intra-cytoplasmic sperms injection (ICSI). Eighty five women entering an ICSI program in the fertility center of Al-Sadr medical city / Al-Najaf Al-Ashraf, from January till April 2015, were enrolled in this study and divided according to BMI to normal weight group [(BMI 18.5-24.9 kg/m 2 ) (n=22)], overweight group [(BMI 25-29.9 kg/m 2 ) (n=43)] and obese group [(BMI≥30 kg/m 2 ) (n=20)]. The patients underwent standard controlled ovarian hyperstimulation protocols and ICSI procedures. The outcome measures in the form of embryological outcomes and most importantly pregnancy rates were studied. The results revealed a significantly negative impact of high BMI in obese women group on total oocytes number retrieved (p value 0.021), mature oocytes number [oocytes in meiosis II (M II)] (p value 0.003), good quality oocytes number (p value 0.005), grade I embryos number (p value 0.040) and clinical pregnancy rate (p value 0.001). On behalf of these results, it is worthy to encourage women with high BMI to lower their body weight before entering an ICSI program.
Hydrophobically-modified intestinal drug delivery

A novel chitosan derivative, O-palmitoyl chitosan (OPC) was synthesized from chitosan and palmitoyl chloride using methane-sulfonic acid as a solvent. The success of synthesis was confirmed by Fourier transform infra-red (FT-IR) spectroscopy and proton NMR spectroscopy (H-NMR). Liposomes encapsulating ferrous sulphate as a model hydrophilic drug for intestinal delivery were prepared with or without OPC inclusion (Lipo-Fe and OPC-Lipo-Fe). Entrapment of iron was significantly higher in OPC containing liposomes compared to controls. Quantitative iron absorption from the OPC liposomes was significantly higher (1.5-fold P < 0.05) than free ferrous sulphate controls. Qualitative uptake analysis by confocal imaging using coumarin-6 dye loaded liposomes also indicated higher cellular uptake and internalization of the OPC-containing liposomes. These findings suggest that addition of OPC during liposome preparation creates robust vesicles that have improved mucoadhesive and absorption enhancing properties. The chitosan derivative OPC therefore provides a novel alternative for formulation of delivery vehicles targeting intestinal absorption. min, 4 °C) and aliquots of the supernatant collected to quantify unassociated drug. Ferrous iron levels in the solution were measured spectrophotometrically at 572 nm using the ferrozine method. 29 Coumarin-6 concentration was determined using a microplate fluorimeter (Fluostar Optima, BMG Labtech, Germany) at 450 nm/505 nm (excitation/emission). The means of three independent readings were recorded and results expressed as mean standard deviation
