Signal-subspace-partition event filtering for eigenvector-based security system using radio waves

This paper proposes signal-subspace-partition event filtering for the event detection system with signal subspace spanned by eigenvector in [3][4]. To detect an event with small changes of signal subspace components, we emphasize the changes of signal subspace components by selecting an appropriate component of signal subspace with signal-subspace partition. In addition, to detect an event in the presence of the changes of signal subspace components due to some undesired movements, such as by a pet, we mask or attenuate the changes of signal subspace components by selecting an appropriate component of signal subspace with signal-subspace partition. In the proposed method, firstly, we estimate direction of arrival (DOA) to obtain the basis of the signal subspace. Next, we make the parted signal subspace by combining each base of the signal subspace. The parted signal subspace is used as the filter. The experimental results reveal that the proposed method can emphasize or mask or attenuate events using signal-subspace partition.
Modeling connectivity to identify current and future anthropogenic barriers to movement of large carnivores: A case study in the American Southwest

Abstract This study sought to identify critical areas for puma (Puma concolor) movement across the state of Arizona in the American Southwest and to identify those most likely to be impacted by current and future human land uses, particularly expanding urban development and associated increases in traffic volume. Human populations in this region are expanding rapidly, with the potential for urban centers and busy roads to increasingly act as barriers to demographic and genetic connectivity of large‐bodied, wide‐ranging carnivores such as pumas, whose long‐distance movements are likely to bring them into contact with human land uses and whose low tolerance both for and from humans may put them at risk unless opportunities for safe passage through or around human‐modified landscapes are present. Brownian bridge movement models based on global positioning system collar data collected during bouts of active movement and linear mixed models were used to model habitat quality for puma movement; then, a wall‐to‐wall application of circuit theory models was used to produce a continuous statewide estimate of connectivity for puma movement and to identify pinch points, or bottlenecks, that may be most at risk of impacts from current and future traffic volume and expanding development. Rugged, shrub‐ and scrub‐dominated regions were highlighted as those offering high quality movement habitat for pumas, and pinch points with the greatest potential impacts from expanding development and traffic, although widely distributed, were particularly prominent to the north and east of the city of Phoenix and along interstate highways in the western portion of the state. These pinch points likely constitute important conservation opportunities, where barriers to movement may cause disproportionate loss of connectivity, but also where actions such as placement of wildlife crossing structures or conservation easements could enhance connectivity and prevent detrimental impacts before they occur.
Situation Modeling in Decision Support Systems

The paper addresses the problem of situation modeling for decision support purposes. Knowledge-based contexts of two types are used for situation modeling. Abstract context is an ontology-based problem model supplied with links to information sources that provide values for the class attributes included in the abstract context. It integrates knowledge relevant to the current situation from an application ontology (a model of a macro situation). Operational context is the abstract context instantiated with the values taken from information sources. It is a situation model along with changeable data. The proposed ideas are illustrated through a case study of disaster relief and evacuation. The concept of modeling situation as context allows decision support systems to take into account dynamic of information
Exploring RNA transcription and turnover in vivo by using click chemistry

We describe a chemical method to detect RNA synthesis in cells, based on the biosynthetic incorporation of the uridine analog 5-ethynyluridine (EU) into newly transcribed RNA, on average once every 35 uridine residues in total RNA. EU-labeled cellular RNA is detected quickly and with high sensitivity by using a copper (I)-catalyzed cycloaddition reaction (often referred to as “click” chemistry) with fluorescent azides, followed by microscopic imaging. We demonstrate the use of this method in cultured cells, in which we examine the turnover of bulk RNA after EU pulses of varying lengths. We also use EU to assay transcription rates of various tissues in whole animals, both on sections and by whole-mount staining. We find that total transcription rates vary greatly among different tissues and among different cell types within organs.
Enriched E-R model to design hybrid database for big data solutions

Advances in database technologies are moving the attention of data managers from well known structured relational databases (SQL-Like DBs) towards NoSQL approaches, especially to address big data issues. However, changing technologies in consolidated data management system is hard and requires great investments. Deploying hybrid SQL-NoSQL approaches could be a good solution to speed up the transition in many domains and information systems, but a formal data model to design hybrid databases is necessary. This paper presents a new data model aimed at solving this issue. Starting from the well known E-R model, we introduce some additional components to identify data and “big data” in the system, in order to drive the implementation of SQL-like solutions to manage data, and NoSQL solutions to manage big data. The paper also discusses a Hospital Information System use case, to clearly show how the proposed enriched E-R model can be successfully adopted.
Minimum Data Set for Home Care: A Valid Instrument to Assess Frail Older People Living in the Community

Background.Optimal care for frail elderly patients depends on comprehensive assessment. This is especially true in the complex setting of interdisciplinary home care programs. To facilitate comprehensive assessment, as well as to generate a useful, policy-relevant patient database, standardized, multidimensional, and validated instruments are very helpful. Objectives.The aim of the present study was to demonstrate that the Minimum Data Set assessment instrument for Home Care (MDS-HC) can be used to detect functional and cognitive impairment as defined by analogous research instruments. Research Design.This was a cross-sectional correlation study. Subjects.We studied 95 patients admitted to home care services of the Health Care Agency of Bergamo (Italy). Measures.The MDS-HC form was completed for all patients by well-trained nurses, independently of and with nurses blinded to the results from the research rating scales. The Barthel Activities of Daily Living (ADL) Index, the Instrumental Activities of Daily Living of Lawton (IADL), and the Mini Mental State Examination (MMSE) were considered the gold standard. Results.Agreement between the MDS-HC scales and the research rating scales was assessed with Pearson’s correlation coefficient. This coefficient was 0.74 for MDS-ADL versus Barthel Index, 0.81 for MDS-IADL versus Lawton Index, and 0.81 for Cognitive Performance Scale versus MMSE, indicating an excellent agreement. Conclusions.The MDS-HC scales, when performed by trained nurses using recommended protocols, provide a valid measure of function and cognitive status in frail home care patients. These findings point out the overall validity of the functional and clinical data contained in the MDS-HC assessment. Use of the MDS-HC gives the unique opportunity of setting up a database, a prerequisite for all epidemiological evidence-based medicine studies.
Performance modelling of generator sets during load acceptance

Traditional generator models, which represent large thermal plants, are simplified on the basis that they are not subjected to large fast-acting electrical transients. Typically these models use a fifth-order synchronous machine and a lower order prime mover model. Although these models are generally suitable for large power system analysis with relatively small-scale disturbances, when these models are used within small networks they cannot be expected to remain representative. When diesel gen-sets are used as a backup supply, they may be expected to supply full rating in a single step from no-load. A gen-set will experience much larger speed and voltage transients than a large thermal plant and a high degree of modelling must take place. This paper presents a gen-set model of engine, synchronous machine, speed governor and voltage regulator
Digital technology in family environment: A case of children from 0 to 6

This research aimed to know the practices with technologies of children up to 6 years old in family environment. I have opted for a qualitative methodology, namely the Grounded Theory, as it was my intention not to be based in existent theories, but to create new ideas and theories from observed reality. For that, I undertook semistructured interviews and observations to 15 Portuguese families in their homes. I resorted to a theoretical sampling, that is, I have look for realities where the phenomenon to be studied existed, thus families would have to have, at least, a child with less than 6 years and preferentially an older sibling. During the data collection I observed that children are surrounded by technologies and use them, in a general way, whenever they wish to, including six-month-old babies. They prefer mobile devices, as tablets and smartphones, but they also use computers, televisions and gaming consoles. Gender is decisive in the chosen activities in the devices, with a general independent use by themselves, leading children to master such devices in a way parents and older siblings do not realize.
Splicing-independent loading of TREX on nascent RNA is required for efficient expression of dual-strand piRNA clusters in Drosophila

In this study, Hur et al. identified a novel function for the TREX complex, which is critical for pre-mRNA processing and mRNA nuclear export. They found that Thoc5 and other TREX components are essential for the biogenesis of noncoding RNA and delineate a novel mechanism for TREX loading on nascent RNA.
Rate Adaptive ACO-OFDM on Multipath Channels for Enhancing Spectral Efficency

In spite of its spectral efficiency problem, asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) is one of widely accepted transmission scheme for intensity modulation/direct detection (IM/DD) based optical wireless communications. In this paper, we analyze the potential of rate adaptive based ACO-OFDM scheme to enhance spectral efficiency of indoor optical wireless communication. Frequency selective based bit loading strategy is used to transmit variable number of bits on different sub carriers having different channel gains. The result of our evaluations confirms that rate adaptive ACOOFDM offers better spectral efficiency compared to fixed modulation formats on all sub carriers.
Implementing a fair monodic temporal logic prover

Monodic first-order temporal logic is a fragment of first-order temporal logic for which sound and complete calculi have been devised. One such calculus is ordered fine-grained resolution with selection, which is implemented in the theorem prover TeMP. However, the architecture of TeMP cannot guarantee the fairness of its derivations. In this paper we present an architecture for a resolution-based monodic first-order temporal logic prover that can ensure fair derivations and we describe the implementation of this fair architecture in the theorem prover TSPASS.
The behavioral ecology of religion: the benefits and costs of one evolutionary approach

Applying evolutionary analyses to the study of religion is fraught with complications and potential misunderstandings. Most notably, the evolutionary sciences do not offer one clear procedure to study religion or any human activity. Here we describe the behavioral ecological approach to religion. We explain the theoretical motivations behind behavioral ecological research and discuss the methodologies employed to conduct this research. We argue that despite its limitations, behavioral ecology can offer important benefits to religious scholarship by providing a coherent and powerful framework for generating, testing and discarding hypotheses about specific aspects of religious behaviors and cultures.
Experiments in program synthesis with grammatical evolution: A focus on Integer Sorting

We present the results of a series of investigations where we apply a form of grammar-based genetic programming to the problem of program synthesis in an attempt to evolve an Integer Sorting algorithm. The results confirm earlier research in the field on the difficulty of the problem given a primitive set of functions and terminals. The inclusion of a swap(i, j) function in combination with a nested for loop in the grammar enabled a successful solution to be found in every run. We suggest some future research directions to overcome the challenge of evolving sorting algorithms from primitive functions and terminals.
Uniform moment bounds of Fisher's information with applications to time series

In this paper, a uniform (over some parameter space) moment bound for the inverse of Fisher's information matrix is established. This result is then applied to develop moment bounds for the normalized least squares estimate in (nonlinear) stochastic regression models. The usefulness of these results is illustrated using time series models. In particular, an asymptotic expression for the mean squared prediction error of the least squares predictor in autoregressive moving average models is obtained. This asymptotic expression provides a solid theoretical foundation for some model selection criteria.
Finite-Element Modeling of Magnetic Material Degradation Due to Punching

Aiming to better understand and model the different loss mechanisms occurring within electric machines during operation, we present a method to consider the degradation of steel during manufacturing due to punching in finite-element modeling of electric machines. The approach introduces a certain number of boundary layers along the punched edges, with the relative permeability decreasing toward the edge. The method, its implementation, and two example applications are presented and supported with experimental results.
Transperitoneal laparoscopic partial nephrectomy using a new technique.

INTRODUCTION We report our experience with a new technique for transperitoneal laparoscopic partial nephrectomy with the kidney turned upside down intraoperatively. MATERIALS AND METHODS Laparoscopic partial nephrectomy was performed in 10 patients with upper pole lesions through a transperitoneal approach. Once complete mobilization of the kidney was achieved, it was rotated 180 degrees around the horizontal axis, so that the upper pole was positioned inferiorly. After performing partial nephrectomy, the resection bed was sutured by 2-0 polyglactin sutures and application of Hem-o-Lok clips. Then, the kidney was returned into its normal position and fixed to the abdominal wall. RESULTS We performed laparoscopic partial nephrectomy on 9 patients with a contrast-enhancing upper pole kidney mass and 1 patient with a nonfunctioning upper pole. The median tumor size was 58 mm (range, 41 mm to 92 mm). The median operative time was 206 minutes (range, 114 to 262 minutes) and the mean warm ischemia time was 30 minutes (range, 22 to 35 minutes). One patient underwent surgical exploration due to bleeding 6 hours after the operation. Prolonged urine leakage (more than 7 days) was observed in 1 patient, which responded to ureteral stent insertion. Surgical margins were negative in all of the patients. Renal cell carcinoma was histologically diagnosed in patients with a kidney tumor. CONCLUSION Laparoscopic upper pole partial nephrectomy had acceptable results while the kidney was turned upside down intraoperatively, in terms of operative time and complications. This approach facilitates the procedure by achieving a better field of vision.
An Aryl Hydrocarbon Receptor-Mediated Amplification Loop That Enforces Cell Migration in ER−/PR−/Her2− Human Breast Cancer Cells

The endogenous ligand-activated aryl hydrocarbon receptor (AHR) plays an important role in numerous biologic processes. As the known number of AHR-mediated processes grows, so too does the importance of determining what endogenous AHR ligands are produced, how their production is regulated, and what biologic consequences ensue. Consequently, our studies were designed primarily to determine whether ER−/PR−/Her2− breast cancer cells have the potential to produce endogenous AHR ligands and, if so, how production of these ligands is controlled. We postulated that: 1) malignant cells produce tryptophan-derived AHR ligand(s) through the kynurenine pathway; 2) these metabolites have the potential to drive AHR-dependent breast cancer migration; 3) the AHR controls expression of a rate-limiting kynurenine pathway enzyme(s) in a closed amplification loop; and 4) environmental AHR ligands mimic the effects of endogenous ligands. Data presented in this work indicate that primary human breast cancers, and their metastases, express high levels of AHR and tryptophan-2,3-dioxygenase (TDO); representative ER−/PR−/Her2− cell lines express TDO and produce sufficient intracellular kynurenine and xanthurenic acid concentrations to chronically activate the AHR. TDO overexpression, or excess kynurenine or xanthurenic acid, accelerates migration in an AHR-dependent fashion. Environmental AHR ligands 2,3,7,8-tetrachlorodibenzo[p]dioxin and benzo[a]pyrene mimic this effect. AHR knockdown or inhibition significantly reduces TDO2 expression. These studies identify, for the first time, a positive amplification loop in which AHR-dependent TDO2 expression contributes to endogenous AHR ligand production. The net biologic effect of AHR activation by endogenous ligands, which can be mimicked by environmental ligands, is an increase in tumor cell migration, a measure of tumor aggressiveness.
La aglomeración urbana: un modelo sencillo

Un fenomeno facilmente constatable cuando uno ve la geografia economica de su pais es la gran aglomeracion que existe de la actividad economica. La poblacion y la produccion no se distribuyen uniformemente en el espacio, sino que en algunos lugares aparecen en mayor medida que en otros. A que se debe este elevado grado de concentracion en ciudades? Por que la gente no se dispersa de forma uniforme en todo el territorio nacional? A la cuestion espacial ya habian intentado dar respuesta economistas de finales del siglo pasado y principios de este, pero hasta hace aproximadamente dos decadas el problema no se abordo desde una optica formal, con fundamentos microeconomicos explicitos. En particular, desde mediados de los 70, la literatura ha ofrecido distintas teorias explicativas relativas al fenomeno de la aglomeracion urbana. En este trabajo se discute este fenomeno y su relacion con la existencia de rendimientos crecientes y se presenta ademas un modelo sencillo que permite analizar este hecho
A 60-GHz 16QAM/8PSK/QPSK/BPSK Direct-Conversion Transceiver for IEEE802.15.3c

This paper presents a 60-GHz direct-conversion transceiver using 60-GHz quadrature oscillators. The transceiver has been fabricated in a standard 65-nm CMOS process. It in cludes a receiver with a 17.3-dB conversion gain and less than 8.0-dB noise figure, a transmitter with a 18.3-dB conversion gain, a 9.5-dBm output 1 dB compression point, a 10.9-dBm saturation output power and 8.8-% power added efficiency. The 60-GHz frequency synthesizer is implemented by a combination of a 20-GHz PLL and a 60-GHz quadrature injection-locked oscillator, which achieves a phase noise of -95 dBc/Hz@l MHz-offset at 60 GHz. The transceiver realizes IEEE802.15. 3c full-rate wireless communication for all 16QAM/8PSK/QPSK/BPSK modes, and the communication distances with the full data rate using 2.16-GHz bandwidth, measured with an antenna built in the package, are 2.7-m (BPSK/QPSK) and 0.2-m (8PSK/16QAM). The measured maximum data rates are 8 Gb/s in QPSK mode and 11 Gb/s in 16QAM mode over a 5 cm wireless link within a bit error rate (BER) of <;10-3. The transceiver consumes 186 mW from a 1.2-V supply voltage while transmitting and 106 mW from 1.0-V supply voltage while receiving. Both transmitter and receiver are driven by a 20-GHz PLL, which consumes 66 mW, including output buffer, from a 1.2-V supply voltage.
A serotype 10 human rotavirus

Rotaviruses with genome rearrangements isolated from a chronically infected immunodeficient child (F. Hundley, M. McIntyre, B. Clark, G. Beards, D. Wood, I. Chrystie, and U. Desselberger, J. Virol 61:3365-3372, 1987) are the first recognized human isolates of serotype 10. This was shown by both a direct enzyme-linked immunosorbent assay and virus neutralization assays using serotype specific monoclonal antibodies. The serotype was confirmed by sequence analysis of the gene encoding VP7, which revealed a 96% amino acid homology to the bovine serotype 10 isolate B223.
Biodegradable Polymer Composite Grafts Promote the Survival and Differentiation of Retinal Progenitor Cells

Retinal progenitor cells (RPCs) are multipotent central nervous system precursors that give rise to all of the cell types of the retina during development. Several groups have reported that mammalian RPCs can be isolated and expanded in culture and can differentiate into retinal neurons upon grafting to the mature, diseased eye. However, cell delivery and survival remain formidable obstacles to application of RPCs in a clinical setting. Because biodegradable polymer/progenitor constructs have been shown to be capable of tissue generation in other compartments, we evaluated the survival, migration, and differentiation of RPCs delivered on PLLA/PLGA polymer substrates to the mouse subretinal space and compared these results to conventional injections of RPCs. Polymer composite grafts resulted in a near 10‐fold increase in the number of surviving cells after 4 weeks, with a 16‐fold increase in cell delivery. Grafted RPCs migrated into the host retina and expressed the mature markers neurofilament‐200, glial fibrillary acidic protein, protein kinase C‐α, recoverin, and rhodopsin. We conclude that biodegradable polymer/progenitor cell composite grafts provide an effective means of increasing progenitor cell survival and overall yield when transplanting to sites within the central nervous system such as the retina.
Molecular Phylogeny of a Potentially Parasitic Dinoflagellate Isolated from the Solitary Radiolarian, Thalassicolla nucleata

ABSTRACT. Thalassicolla nucleata, a solitary radiolarian, has been described as being parasitized by two dinoflagellates, Solenodinium (Syndiniales) and Caryotoma (Blastodiniales). Several T. nucleata were stripped of their extracapsular material and allowed to regenerate their rhizopodial structures without symbionts. Within a week, two were observed to disintegrate, leaving behind non‐pigmented swimming dinoflagellate cells. Identical full‐length ribosomal sequences were recovered from both samples. Upon alignment and phylogenetic analysis, it was determined that these putative parasite sequences were distinct from Scrippsiella nutricula (the dinoflagellate symbiont of the host), and also from all other dinoflagellate parasites sequenced to date.
