New SEC-DED-DAEC codes for multiple bit upsets mitigation in memory

Nowadays, multiple bit upsets (MBUs) have been widely investigated in memories. Conventional single error correction and double error detection (SEC-DED) codes are capable of correcting one error and detecting all possible double errors. However, they may not provide adequate protection against MBUs. This paper proposes new singleerror-correction, double-error-detection double-adjacenterror-correction (SEC-DED-DAEC) codes to mitigate radiation or noise source induced MBUs in memories. The proposed SEC-DED-DAEC codes are obtained from conventional SEC-DED codes according to the mathematics model established in this paper. They can detect and correct all adjacent double bit errors and assure a lower miscorrection probability for non-adjacent double bit errors compared with other SEC-DED-DAEC codes. Furthermore, the redundancy bits of the proposed scheme are the same as those of conventional SEC-DED codes. This means that the increase of correct-capability do not cause additional hardware overhead for the memory system. Finally, the experiment results reveal that the proposed scheme reduces the miscorrection probability of non-adjacent double bit errors by 12% compared to the best known SEC-DED-DAEC codes. Moreover, compared to the well known BCH codes, the proposed scheme reduces 40% hardware redundancy and keeps an acceptable reliability. Keywords-memroy; memroy reliability; SEC-DED-DAEC codes; MBUs
Hybrid performance and heterosis in early segregant populations of Brazilian spring wheat.

The objective of this study was to estimate the inbreeding depression and heterosis relative to the mid-parent and better parent for grain yield and yield components in a set of diallel crosses involving 10 wheat genotypes. Parents and F1 and F2 hybrids were evaluated under field conditions using a spaced plant scheme in a randomized block design with three replications. The heterosis, heterobeltiosis and inbreeding depression for agronomic traits were calculated. There was a negative correlation between the heterobeltiosis and grain yield per plant (GYP) inbreeding depression, indicating the presence of positive additive additive epistatic interactions. The mean GYP values for the F1 and F2 progenies were 20 and 10% higher, respectively, compared with the parents, indicating that the hybrids were superior to the parents. The heterosis of the number of spikes per plant in the F1 and F2 generations can be a useful approach for the indirect selection of wheat plants with an improved grain weight and grain yield per plant. The study reveals good scope for isolation of pure lines from the progenies of heterotic F1's as well as commercial exploitation of heterosis in spring wheat.

STACY: Um Novo Algoritmo para Automaticamente Classificar a Força dos Relacionamentos ao Longo dos Anos

Entender relacionamentos entre pessoas em uma rede social e medir suas forças ao longo do tempo são problemas interessantes com várias aplicações. Aqui, propomos um novo algoritmo (STACY) para automaticamente classificar a força dos relacionamentos em oito diferentes classes considerando o aspecto temporal. Os resultados mostram que tais classes representam e distinguem relacionamentos, e STACY é capaz de identificar relacionamentos fortesque persistem mais do que os classificados por um algoritmo do estado-da-arte.
Healthcare's Future: Strategic Investment in Technology

SUMMARY Recent and rapid advances in the implementation of technology have greatly affected the quality and efficiency of healthcare delivery in the United States. Simultaneously, diverse generational pressures—including the consumerism of millennials and unsustainable growth in the costs of care for baby boomers—have accelerated a revolution in healthcare delivery that was marked in 2010 by the passage of the Affordable Care Act. Against this backdrop, Maryland and the Centers for Medicare & Medicaid Services entered into a partnership in 2014 to modernize the Maryland All-Payer Model. Under this architecture, each Maryland hospital negotiates a global budget revenue agreement with the state's rate-setting agency, limiting the hospital's annual revenue to the budgetary cap established by the state. At Atlantic General Hospital (AGH), leaders had established a disciplined strategic planning process in which the board of trustees, medical staff, and administration annually agree on goals and initiatives to achieve the objectives set forth in its five-year strategic plans. This article describes two initiatives to improve care using technology. In 2006, AGH introduced a service guarantee in the emergency room (ER); the ER 30-Minute Promise assures patients that they will be placed in a bed or receive care within 30 minutes of arrival in the ER. In 2007, several independent hospitals in the state formed Maryland eCare to jointly contract for intensive care unit (ICU) physician coverage via telemedicine. This technology allows clinical staff to continuously monitor ICU patients remotely. The positive results of the ER 30-Minute Promise and Maryland eCare program show that technological advances in an independent, small, rural hospital can make a significant impact on its ability to maintain independence. AGH's strategic investments prepared the organization well for the transition in 2014 to a value-based payment system.
Palladium(II) Acetylide Complexes with Pincer-Type Ligands: Photophysical Properties, Intermolecular Interactions, and Photo-cytotoxicity.

Two classes of cationic palladium(II) acetylide complexes containing pincer-type ligands, 2,2':6',2''-terpyridine (terpy) and 2,6-bis(1-butylimidazol-2-ylidenyl)pyridine (C^N^C), were prepared and structurally characterized. Replacing terpy with the strongly σ-donating C^N^C ligand with two N-heterocyclic carbene (NHC) units results in the PdII acetylide complexes displaying phosphorescence at room temperature and stronger intermolecular interactions in the solid state. X-ray crystal structures of [Pd(terpy)(C≡CPh)]PF6 (1) and [Pd(C^N^C)(C≡CPh)]PF6 (7) reveal that the complex cations are arranged in a one-dimensional stacking structure with pair-like PdII ⋅⋅⋅PdII contacts of 3.349 Å for 1 and 3.292 Å for 7. Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations were used to examine the electronic properties. Comparative studies of the [Pt(L)(C≡CPh)]+ analogs by 1 H NMR spectroscopy shed insight on the intermolecular interactions of these PdII acetylide complexes. The strong Pd-Ccarbene bonds render 7 and its derivative sufficiently stable for investigation of photo-cytotoxicity under cellular conditions.
Mathematical model and experimental investigation of polycarbonate pellet drying

An easy to use, spreadsheet based, mathematical model for drying of strand cut polymer pellets has been developed and experimentally verified. This particle-scale model is based on internal mass-transfer controlled diffusion in the pellet. Examples of its usage in correlation and prediction of the effects of the drying-gas temperature, humidity, and pellet dimensions are presented. Application of the particle-scale model to the design of a countercurrent hopper drier is discussed. Even though examples are limited to water removal from poly(bisphenol-A)carbonate pellets, the model is general and may be used for the removal of other non-solvating low-concentration molecules from polymers with isotropic morphology.
Assessing the Usability of Gaze-Adapted Interface against Conventional Eye-Based Input Emulation

In recent years, eye tracking systems have greatly improved, beginning to play a promising role as an input medium. Eye trackers can be used for application control either by simply emulating the mouse and keyboard devices in the traditional graphical user interface, or by customized interfaces for eye gaze events. In this work, we evaluate these two approaches to assess their impact in usability. We present a gaze-adapted Twitter application interface with direct interaction of eye gaze input, and compare it to Twitter in a conventional browser interface with gaze-based mouse and keyboard emulation. We conducted an experimental study, which indicates a significantly better subjective user experience for the gaze-adapted approach. Based on the results, we argue the need of user interfaces interacting directly to eye gaze input to provide an improved user experience, more specifically in the field of accessibility.
Physicochemical and microbiological characteristics of surimi seafood under thermal and E-beam processing

approved: , „ JaeW.W-k Effects of thermal and electron beam (e-beam) processing on microbial inactivation and physichochemical properties of surimi and surimi seafood were investigated. Thermal-death-time (TDT) concept was used to model Staphylococcus aureus inactivation by heat and e-beam. Gumey-Lurie charts were used to estimate temperature during thermal processing of surimi seafood. Dose mapping technique was used to estimate dose absorbed by surmi seafood during ebeam processing. The dose absorbed increased up to 2 cm and then it gradually decreased, reaching a minimum at 5 cm depth of surimi seafood. It was determined that one and two-sided e-beam can efficiently penetrate 3.3 and 8.2 cm of surimi seafood, respectively. The D-value for thermally inactivated S. aureus was 0.65, 1.53, 6.52, 49.83, and 971.54 s, at 95, 85, 75, 65, and 55C, respectively. TheDvalue for S. aureus inactivated with e-beam was 0.34 kGy. The z-value for thermally inactivated S. aureus between 55-95C was not linear. Thermal processing degraded texture and color of surimi seafood. E-beam enhanced firmness and decreased the b* value of surimi seafood. Myosin heavy chain (MHC) degraded proportionally to the e-beam dose. Actin was not affected by ebeam except treatment at 25 kGy. Hydrophobic interactions and disulfide bonds were formed in raw Alaska pollock surimi when treated with e-beam.

A Few Biologically Inspired Security Mechanisms

Biology has been a rich source of terminology for computer security, especially in the area of malware analysis and defense. However, many computer security professionals lack in-depth knowledge on these underlying biological mechanisms and thus have difficulties in making a smooth transition between biological phenomena and their application in computer security. As a result the security mechanisms developed by nature have yet to be fully utilized in the arena of digital attacks and defenses. In this paper we introduce a few biological security mechanisms, such as the cryptographic and steganographic processing of biological information expressed in DNA, RNA, and protein sequences, the defensive actions against invading pathogens conducted by biological immune system, and the improved survivability of a species through bio-diversity, to the practitioners working in the field of information security. The intentions are two folds: (1) To build computer systems with built-in/inherent security mechanisms, unlike the common practice today – security is an adds-on feature; (2) To seek new security paradigms from the most recent developments in biology. Due to the interdisciplinary nature of the subject, it is necessary to encourage researchers from both computer science and biology to participate to achieve the goals.
Ultra-Reliable and Low-Latency Communications in 5G Downlink: Physical Layer Aspects

URLLC is a new service category in 5G to accommodate emerging services and applications having stringent latency and reliability requirements. In order to support URLLC, there should be both evolutionary and revolutionary changes in the air interface named 5G NR. In this article, we provide an up-to-date overview of URLLC with an emphasis on the physical layer challenges and solutions in 5G NR downlink. We highlight key requirements of URLLC and then elaborate the physical layer issues and enabling technologies including packet and frame structure, scheduling schemes, and reliability improvement techniques, which have been discussed in the 3GPP Release 15 standardization.
Towards secure and standard-compliant implementations of the PSD2 Directive

The present article provides a compact overview of the most important requirements of the so-called “Payment Services Directive 2” (PSD2) [Di15], together with the related Regulatory Technical Standard on authentication and communication [Eu17] according to Article 98, and outlines how the pivotal “Access-to-Account-Interface” can be securely implemented based on widely acknowledged international standards.
Activity of mesenchymal stem cells in therapies for chronic skin wound healing

Chronic or non-healing skin wounds present an ongoing challenge in advanced wound care, particularly as the number of patients increases while technology aimed at stimulating wound healing in these cases remains inefficient. Mesenchymal stem cells (MSCs) have proved to be an attractive cell type for various cell therapies due to their ability to differentiate into various cell lineages, multiple donor tissue types, and relative resilience in ex-vivo expansion, as well as immunomodulatory effects during transplants. More recently, these cells have been targeted for use in strategies to improve chronic wound healing in patients with diabetic ulcers or other stasis wounds. Here, we outline several mechanisms by which MSCs can improve healing outcomes in these cases, including reducing tissue inflammation, inducing angiogenesis in the wound bed, and reducing scarring following the repair process. Approaches to extend MSC life span in implant sites are also examined.
PbTe quantum dots multilayer for optical switching device

In this work we report the fabrication of PbTe quantum dots multilayers embedded in SiO2 by alternatively use of Laser Ablation and Plasma Enhanced Chemical Vapor Deposition techniques. The quantum dots were grown by pulsed laser deposition (PLD) of a PbTe target using the second harmonic of a Q-Switched Quantel Nd:YAG laser in high purity argon atmosphere. The glass matrix was fabricated by PECVD using tetramethoxysilane (TMOS) as precursor. The RF power was supplied by a RF-150 TOKYO HI-Power operating at 13.56 MHz and coupled to the RF electrodes through a matching box. The deposition rates as well as the best growth parameters for both the nanoparticles and the glass matrix were obtained from a previous work. The morphological properties of the nanostructured material were studied by means of igh Resolution Transmission Electron Microscopy(HRTEM), grazing-incidence small-angle X-ray scattering (GISAXS) and X-ray reflectometry . Unlike HRTEM, which extracts information of a submicron region of the sample and only a few thousand particles are observed, GISAXS signal is obtained through an average over orders of magnitude larger number of particles (perhaps 1012 particles) distributed over an area of tens of square millimeters. This fact means that GISAXS sampling is much more representative of the sample as whole. Finally, multilayers were grown inside a Fabry-Perot cavity. The complete system operates as an optical switching device for the infrared region. The device was characterized by Scanning Electron Microscopy and optical absorption.
Recognizing Ureter and Uterine Artery in Endoscopic Images Using a Convolutional Neural Network

Endoscope-based surgery has several beneficial effects regarding the rehabilitation of the patients, but has some drawbacks causing difficulties to medical experts, on the contrary. The main disadvantage is that the tactile information is loosed to expert who takes the surgical intervention. There are some organs (e.g. ureters and arteries) in the human body which have similar visual appearances, so the differentiation of them based on only visual expression via endoscopy is a challenging task to the medical experts. To support keyhole-surgery using state-of-the-art image processing solutions, we have developed a semi-automatic software which can distinguish ureters from arteries by a dedicated convolutional neural network (CNN). We have trained the CNN on 2000 images acquired during endoscopic surgery and tested on 500 test ones. 94.2% accuracy has been achieved in this two-classes classification task regarding a binary error function.
Importance of bovine mastitis in Africa

Abstract Bovine mastitis is an important animal production disease that affects the dairy industry globally. Studies have estimated the prevalence of this disease in approximately 30% of African countries, with the highest prevalence found in Ethiopia. This is despite the wide cattle distribution in Africa, and the largest number of dairy farms and herds in countries such as South Africa, Kenya and Uganda. Furthermore, the estimated financial losses due to direct and indirect impacts of bovine mastitis are lacking in this continent. Therefore, intensive research efforts will help determine the continent-wide economic impacts and advance careful monitoring of disease prevalence and epidemiology. Here, published cases supporting the occurrence and importance of bovine mastitis in certain regions of Africa are outlined.
Attribute Selection for Partially Labeled Categorical Data By Rough Set Approach

Attribute selection is considered as the most characteristic result in rough set theory to distinguish itself to other theories. However, existing attribute selection approaches can not handle partially labeled data. So far, few studies on attribute selection in partially labeled data have been conducted. In this paper, the concept of discernibility pair based on rough set theory is raised to construct a uniform measure for the attributes in both supervised framework and unsupervised framework. Based on discernibility pair, two kinds of semisupervised attribute selection algorithm based on rough set theory are developed to handle partially labeled categorical data. Experiments demonstrate the effectiveness of the proposed attribute selection algorithms.
A Unified Alternating Direction Method of Multipliers by Majorization Minimization

Accompanied with the rising popularity of compressed sensing, the Alternating Direction Method of Multipliers (ADMM) has become the most widely used solver for linearly constrained convex problems with separable objectives. In this work, we observe that many existing ADMMs update the primal variable by minimizing different majorant functions with their convergence proofs given case by case. Inspired by the principle of majorization minimization, we respectively present the unified frameworks of Gauss-Seidel ADMMs and Jacobian ADMMs, which use different historical information for the current updating. Our frameworks generalize previous ADMMs to solve the problems with non-separable objectives. We also show that ADMMs converge faster when the used majorant function is tighter. We then propose the Mixed Gauss-Seidel and Jacobian ADMM (M-ADMM) which alleviates the slow convergence issue of Jacobian ADMMs by absorbing merits of the Gauss-Seidel ADMMs. M-ADMM can be further improved by backtracking and wise variable partition. We also propose to solve the multi-blocks problems by Proximal Gauss-Seidel ADMM which is of the Gauss-Seidel type. It convegences for non-strongly convex objective. Experiments on both synthesized and real-world data demonstrate the superiority of our new ADMMs. Finally, we release a toolbox that implements efficient ADMMs for many problems in compressed sensing.
Extended endonasal approach versus maxillary swing approach to the parapharyngeal space

The nasopharyngeal and parapharyngeal spaces are difficult for surgeons to access. Of the various external routes described, the maxillary swing has emerged as the gold standard because of its simplicity. However, its morbidity has led to the development of less invasive techniques. The purpose of our study was to compare the surgical anatomy of the maxillary swing with that of the endoscopic endonasal approach.
Blind quality assessment of JPEG compressed images

This letter presents a no-reference image quality assessment algorithm for measuring blockiness in JPEG compressed images. The proposed metric dubbed BRIBE (Blind/Referenceless Image Blockiness Estimate) operates in the spatial domain and straightaway targets artifacts which cause visual annoyance instead of explicitly incorporating characteristics of the Human Visual System (HVS). It is observed that the presence of horizontal and vertical image gradients at block boundaries along with block flatness is responsible for quality degradation in JPEG compressed images. Both these factors are mathematically captured and finally weighted to obtain the proposed BRIBE index. Experimental results on four JPEG image quality databases show that BRIBE statistically outperforms existing indices on LIVE IQA database and performs at par with them on other databases. A software release of the model is available at https://sites.google. com/site/blindiqa/bribe.
Preferences for Communicating about Breast Cancer Screening Among Racially/Ethnically Diverse Older Women

ABSTRACT Differences exist across breast cancer screening guidelines regarding frequency of screening and age of discontinuation for older women (≥70 years) at average risk for breast cancer. These differences highlight concerns about the benefits and harms of screening, and may negatively impact older women’s ability to make informed screening decisions. This study examined preferences for communicating about screening mammography among racially/ethnically diverse, older women. In-depth interviews were conducted with 59 women with no breast cancer history. Non-proportional quota sampling ensured roughly equal numbers on age (70–74 years, ≥75 years), race/ethnicity (non-Hispanic/Latina White, non-Hispanic/Latina Black, Hispanic/Latina), and education (≤high school diploma, >high school diploma). Interviews were audio-recorded, transcribed, and analyzed using NVivo 10. Thematic analyses revealed that rather than being told to get mammograms, participants wanted to hear about the benefits and harms of screening mammography, including overdiagnosis. Participants recommended that this information be communicated via physicians or other healthcare providers, included in brochures/pamphlets, and presented outside of clinical settings (e.g., in senior groups). Results were consistent regardless of participants’ age, race/ethnicity, or education. Findings revealed that older women desire information about the benefits and harms of screening mammography, and would prefer to learn this information through discussions with healthcare providers and multiple other formats.
Comparing new Keynesian models in the Euro area: a Bayesian approach

This paper estimates and compares four versions of the sticky price New Keynesian model for the Euro area using a Bayesian approach. We find that the average duration of price contracts is between two and four quarters, while the average duration of wage contracts is estimated to be below two quarters. Both mechanisms of price and wage indexation are not important when autocorrelated price markup shocks are introduced in the model. These results are in stark contrast to Smets and Wouters (2003): when we use their priors, our estimated posterior distributions are similar to theirs, but the models’ fit to the data is worse.
