Delineation of Iron Alteration Zones using Spectrum-Area Fractal Model and TOPSIS Decision-Making Method in Tarom Metallogenic Zone, NW Iran

Signal analysis approaches are a powerful and widely used tool in processing multispectral satellite images for detection of alteration zones. The main goal of this work is application of the spectrum-area fractal methodology based on the Landsat 8 OLI satellite images’ data for separation alteration zones for iron oxides at the Tarom region (NW Iran). These alteration zones, Normalized Difference Vegetation Index (NDVI), and Normalized Difference Water Index (NWDI) are detected using the band-ratio and band combination methods. Then the calculated values are categorized by Spectral Angle Mapper (SAM), k-means, and S-A fractal model. Considering a positive correlation of iron oxides alterations along with magnetite mineralization as an index of mineralization at the studied region, the promising areas are classified by a decision-making model using the TOPSIS method with an acceptable accuracy for presenting in the exploration models.
Wireless Network Security: Challenges, Threats and Solutions. A Critical Review

: Wireless security is the avoidance of unlawful access or impairment to computers using wireless networks. Securing wireless network has been a research in the past two decades without coming up with prior solution to which security method should be employed to prevent unlawful access of data. The aim of this study was to review some literatures on wireless security in the areas of attacks, threats, vulnerabilities and some solutions to deal with those problems. It was found that attackers (hackers) have different mechanisms to attack the networks through bypassing the security trap developed by organizations and they may use one weak pint to attack the whole network of an organization. However the author suggested using firewall in each wireless access point as the counter measure to protect data of the whole organization not to be attacked.
Thermal Degradation Study of Waste Polymer Matrix Polypropylene and Polyvinyl Chloride as Polymer Matrix Filled Rice Husk Decking Structure

The aim of this study is to find another alternative material to replace the additives of polymeric materials. From previous works, woodchips are used to act as filler instead of rice husk. Thus, in this case, the woodchips is being exchange with rice husk and mixed with the waste polymer in order to reduce the cost. This study is about the effect of thermal towards the mechanical and physical properties of this WPC. Therefore, heat test and UV Irradiation Exposure test were conducted on this wood polymer composite (WPC). Then, three pa-rameters were being examined which were difference in density, hardness and physical properties after undergoing heat test and UV Irradiation Exposure test. The density and hardness appearances from both test only had slightly reduction and it can be considered as negligible. The physical changes were not too apparent such as crack that would lead to failure even after being heated and exposed to the UV light for a long period. Thus, it proves that rice husk could replace woodchips in order to be used as decking structure.
IFN-Dependent Antiviral Immune Responsesin Domain-Like Receptor NLRC5 Is Involved The Nucleotide Oligomerization Binding

Nucleotide oligomerization binding domain-like receptors (NLRs) are a group of intracellular proteins that mediate recognition of pathogen-associated molecular patterns or other cytosolic danger signals. Mutations in NLR genes have been linked to a variety of inﬂammatory diseases, underscoring their pivotal role in host defense and immunity. This report describes the genomic organization and regulation of the human NLR family member NLRC5 and aspects of cellular function of the encoded protein. We have analyzed the tissue-speciﬁc expression of NLRC5 and have characterized regulatory elements in the NLRC5 promoter region that are responsive to IFN- g . We show that NLRC5 is upregulated in human ﬁbroblasts postinfection with CMV and demonstrate the role of a JAK/STAT-mediated autocrine signaling loop involving IFN- g . We demonstrate that overexpression and enforced oligomerization of NLRC5 protein results in activation of the IFN-responsive regulatory promoter elements IFN- g activation sequence and IFN-speciﬁc response element and upregulation of antiviral target genes (e.g., IFN- a , OAS1 , and PRKRIR ). Finally, we demonstrate the effect of small interfering RNA-mediated knockdown of NLRC5 on a target gene level in the context of viral infection. We conclude that NLRC5 may represent a molecular switch of IFN- g activation sequence/IFN-speciﬁc response element signaling pathways contributing to antiviral defense mechanisms.

Comparison of PAPR Reduction Companding Techniques of OFDM Signal

- the major drawbacks which is yet to be solved in orthogonal frequency division multiplexing (OFDM) system is its high peak-to-average power ratio (PAPR). In this paper, different companding transform scheme are compared which are nonlinear in nature and which transforms the Gaussian-distributed OFDM signals into a desired piecewise function. variable slopes and inflexion points is introduced in the target probability density function, to impart more flexibility in the companding form and an effective trade-off between the PAPR and bit error rate performances can be achieved along with a relatively low complexity. The theoretical analyses of different techniques and trade-off between PAPR reduction and bit error ratio (BER) performance are presented well.
Community EQ: Empathy as a KPI in Post-COVID19 Business Culture

This white paper proposes that community empathy—in other words, actively practicing collective empathy—be a core element of the future of work in all business organizations, and that it be embraced actively as a key performance indicator using socio-technological solutions. First of all, we present the current state of work as it intersects with (post)COVID19 society, drawing attention to the urgency and recognized need for nurturing “soft” human capabilities like empathy among all employees. We then dive deep into the concept of empathy as it is being harnessed and monetized around the world for the betterment of business and society at large, and argue for a capabilities approach to working with empathy. We also critically reflect on the methods that have been used to create community within business organisations, and share insights into the human science behind community building, and collective thinking and feeling. The solution we propose is to co-create spaces that are conducive to nurturing the practice of empathy. This is a multidimensional process which involves having a good understanding of what empathy actually is, curation, preparation, and the mindful matching of people. In addition to expanding on these dimensions, we provide tips for designing the settings for the encounter(s), and emphasize the importance of reflection and feedback, and the crucial role of consistency and repetition in habit formation. The paper concludes with a succinct overview of the outcomes we as human beings, as employees, as employers, as family members, as citizens and denizens can expect to enjoy as our empathetic capabilities increase - not only at work but also in all of our social relations and interactions.
Cells That Await Pregnancy Endometrial NK Cells Are Special Immature

NK cells populate the human endometrium before pregnancy. Unlike decidual NK cells that populate the decidua during pregnancy, the NK cells present in the human endometrium, before pregnancy, have not been fully characterized. In this study, we provide a detailed analysis of the origin, phenotype, and function of endometrial NK cells (eNK). We show that eNK cells have a unique receptor repertoire. In particular, they are negative for NKp30 and chemokine receptor expression, which distinguishes them from any other NK subset described so far. We further show that eNK cells lack NK-speciﬁc functional phenotype and activity such as cytokine secretion and cytotoxicity, before IL-15 stimulation. Following such stimulation, endometrial NK cells acquire phenotype and function that are similar to those of decidual NK cells. We therefore suggest that eNK cells are inactive cells (before IL-15 activation and in relation to the known NK activity) that are present in the endometrium before conception, waiting for pregnancy.

Rapid authentication of European sea bass (Dicentrarchus according method, farming geographical origin near infrared coupled with

Chemometric analysis of near-infrared spectroscopy (NIRS) data was applied to investigate the possibility to rapidly authenticate European sea bass ( D ICENTRARCHUS LABRAX L.) according to production method (wild or farmed), rearing system (extensive, semi-intensive or intensive), and geographical origin (Western, Central or Eastern Mediterranean Sea). NIR spectra from 1100 to 2500 nm were subjected to an exploratory principal component analysis (PCA) followed by orthogonal partial last square-discriminant analysis (OPLS-DA) to develop classifiers able to distinguish samples according to the various conditions under study. Models provided a correct classification rate of 100% for both wild and farmed sea bass, and of 67%, 80%, 100% for extensively, semi-intensively, and intensively-reared subjects, respectively. As for geographical provenance, 100% of Eastern, 88% of Central and 85% of Western Mediterranean Sea samples were correctly discriminated. The successful results obtained confirmed suitability of chemometric analysis applied to NIRS data for fast authentication of European sea bass origin.

RIIB g Cell Receptor Is an Early Target of Fc Antigen-Induced Oligomerization of the B

The Fc g RIIB is a potent inhibitory coreceptor that blocks BCR signaling in response to immune complexes and, as such, plays a decisive role in regulating Ab responses. The recent application of high-resolution live cell imaging to B cell studies is providing new molecular details of the earliest events in the initiation BCR signaling that follow within seconds of Ag binding. In this study, we report that when colligated to the BCR through immune complexes, the Fc g RIIB colocalizes with the BCR in microscopic clusters and blocks the earliest events that initiate BCR signaling, including the oligomerization of the BCR within these clusters, the active recruitment of BCRs to these clusters, and the resulting spreading and contraction response. Fluorescence resonance energy transfer analyses indicate that blocking these early events may not require molecular proximity of the cytoplasmic domains of the BCR and Fc g RIIB, but relies on the rapid and sustained association of Fc g RIIB with raft lipids in the membrane. These results may provide novel early targets for therapies aimed at regulating the Fc g RIIB to control Ab responses in autoimmune disease. The Journal of Immunology , 2010, 184: 000–000.

Infl ammatory phenotype of circulating endothelial-derived microparticles in chronic heart failure patients with metabolic syndrome

Current clinical, experimental, and epidemiological observations define metabolic syndrome (MetS) as a risk factor clustering related to the development of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) [1]. According currently statement, the MetS includes abdominal obesity, insulin resistance (IR), dyslipidemia, elevated blood pressure (BP), and associated with other comorbidities including the prothrombotic and proinflammatory states [2]. Recent studies have emerged that genetic, early-life-depended, age-related, and sociodemographic factors, as well as dietary particularities, coexisting comorbidities are discussed leading causes for the current prevalence of MetS in the general population [3-5]. Therefore, MetS corresponds with several cardiovascular risk factors and associates with an increased incidence of T2DM, cardiovascular events, and mortality [6]. The underlying pathophysiological mechanisms resulting in the MetS, IR, central obesity, are not fully understood. However, activated immunity and cytokine production, oxidative stress may effect on a development of cardiovascular complications through inducing endothelial dysfunction [7-10]. There is evidence that systemic pro-inflammatory response induced by MetS is cause of microvascular endothelial cell inflammation [11,12]. Although the adverse prognostic impact of T2DM in unselected populations and in patients with chronic heart failure (CHF) has been previously shown [13-15], the role of MetS in CHF subjects remains controversial [16-18]. It has suggested that endothelial-derived microparticles (EMPs) may play a pivotal role in cell-to-cell cooperation, negatively affects tissue reparation, and mediates vascular function [19].

Theoretical studies of the formation mechanism of protein complex by using coarse-grained models

Protein is an essential element in every cell of living organisms. Most proteins form a complex to perform its function. The formation of complex system involves protein—protein interaction, which is becoming a great issue in biomolecular studies. In recent times, rapid development on computational study of protein—protein interaction has been greatly advanced by various approaches. In this thesis, coarse-grained models were developed to address several issues, which are unfolding process, crowding effects, and stability of protein complex. Current study will focus on protein azurin, which is known as an extremely stable protein. To observe the stability and dynamics of azurin, structural properties were evaluated. These studies suggested that the G ō -like model is the most accurate model yet lacks transferability. To find more transferable potential model, more physical information are needed for better approach. Hopefully many important insights will be provided by these studies.

Management Driven Multicast Protocol with End-to-End QoS

— Multicast technologies supporting various media services are increasingly seen in the current Internet and are expected to be used also in future Internet deployments. While traditional IP level multicast and overlay multicast are well known solutions, multi-domain multicast with quality of services (QoS) guarantees is still a research topic. This paper proposes a management driven hybrid multicast system and protocol, QoS enabled and spanning multiple IP domains. Starting from a previously defined architecture, the management system is developed and then, the protocol design, implementation and some performance evaluation are presented.

We describe the synthesis of a new substrate for the detection of bacterial b-galactosidase. This substrate, alizarin-b-D-galactoside, is readily hydrolysed to release alizarin which complexes with various metal ions to form brightly coloured chelates. A total of 367 strains of Gramnegative bacteria were examined for their ability to hydrolyse three chromogenic substrates: alizarin-b-D-galactoside (Aliz-gal), cyclohexenoesculetin-b-D-galactoside (CHE-gal) and 5bromo-4-chloro-3-indolyl-b-D-galactoside (X-gal). A total of 182 strains (49 6%) were found to hydrolyse at least one of the three substrates. All of these 182 strains (100%) hydrolysed Aliz-gal whereas only 170 (93 4%) and 173 (95 1%) hydrolysed CHE-gal and X-gal, respectively. We conclude that alizarin-b-D-galactoside is a highly sensitive substrate for the demonstration of b-galactosidase.
Real-time Hand Gesture Recognition System and Application

In some circumstances where hands cannot conveniently touch equipment, the hand gesture recognition system is a good solution for HCI. A real-time hand gesture sensing and recognition system is proposed and its application to TV channel and volume control is examined in this study. The digital signal processor (DSP) DM6437 of Texas Instruments is used in our portable hand gesture recognition system. For the real-time recognition of hand gestures, we propose a novel finger skin pixel algorithm to quickly and easily distinguish the hand in a complex image. The region of interest is used to reduce the amount of computation. Hand features are detected in two steps. First, the thumb and pinkie are recognized on the basis of significant shape features. Second, a circle is defined from the hand center for threshold decomposition to count the number of fingers. The hand gesture recognition rate is 94.3%. The hand trace direction can be found easily by using a hand gesture center point in our system. Finally, our system is applied to TV channel and volume control using hand gestures and hand tracing.
Study of the Resistive Bridging Impact on the Delay in QDI Countermeasures

 Abstract — The present paper highlights the impact of the resistive bridging faults on the delay in secured CMOS 45 nm technology implemented in quasi delay insensitive (QDI) countermeasure. We have analyzed the static and the dynamic behavior of resistive bridges as a function of its unpredictable resistance. We showed that the defect detection depends upon both conditions i.e., the value of the bridging resistance and the vectors that have applied to the circuit entry. The delay estimation induced by the resistive bridging faults is observed and analyzed.
Oxidative Stress and Gamma Radiation-induced Cancellous Bone Loss 1

Astronauts in space are exposed to radiation while weightless, which may 19 contribute to subsequent bone loss. Gamma irradiation of post-pubertal mice 20 rapidly increases the number of bone-resorbing osteoclasts and causes bone 21 loss in cancellous tissue; similar changes also occur in skeletal diseases 22 associated with oxidative stress. Therefore, we hypothesized that increased 23 oxidative stress mediates radiation-induced bone loss and that musculoskeletal 24 disuse changes the sensitivity of cancellous tissue to radiation exposure. Musculoskeletal disuse by hindlimb unloading (1 or 2 weeks) or total body gamma irradiation (1 or 2 Gy of 137 Cs) of four-month mice 27 each decreased cancellous bone volume fraction in the proximal tibiae and 28 lumbar vertebrae. The extent of irradiation-induced acute cancellous bone loss in 29 both tibiae and lumbar vertebrae was similar in normally loaded and hindlimb 30 unloaded mice. Similarly, osteoclast surface in the tibiae increased 46% due to 31 irradiation, 47% due to hindlimb unloading, and 64% due to irradiation and 32 hindlimb unloading combined, when compared to normally loaded mice. 33 Irradiation, but not hindlimb unloading, reduced viability and increased apoptosis 34 of marrow cells and caused oxidative damage to lipids within mineralized tissue. 35 Irradiation also stimulated ROS generation in marrow cells. Furthermore, 36 injection of α -lipoic acid, an anti-oxidant, mitigated the acute bone loss caused by 37 irradiation. Together, these results showed that disuse and gamma irradiation, 38 alone or combined, caused a similar degree of acute cancellous bone loss and show
Consiglio Nazionale delle Ricerche A Clustering Technique for Customized Video Storyboard

Web video browsing is rapidly becoming a very popular activity in the Web scenario, causing the production of a concise video content representation a real need. Currently, static video summary techniques can be used to this aim. Unfortunately, they require long processing time and hence all the summaries are produced in advance without any users customization. With an increasing number of videos and with the large users heterogeneousness, this is a burden. In this paper we propose a new summarization technique that produces customized on-the-ﬂy video storyboards. The mechanism uses a fast clustering algorithm that selects the most representative frames using their HSV color distribution and allows users to select the storyboard length and the processing time. An objective and subjective evaluation shows that the storyboards are produced with good quality and in a time that allows on-the-ﬂy usage.
