The Ciudad Sindical de Vacaciones [Vacation City for Workers] (VCW) constitutes a reference of leisure architecture in Spain during the Franco regime. Starting with a literature review and the process of its cataloguing and protection, the focus lies on the last of these structures ever to be implemented, built in Marb... |
In this paper, an ultra-step-up DC-DC converter using a three-winding coupled inductor and a voltage multiplier cell are proposed to achieve high step-up voltage. The important advantages of the proposed converter are as: Only one active switch is required without extreme duty cycle that high voltage is attained, The v... |
Antisense RNA was a rather uncommon term in a physiology environment until short interfering RNAs emerged as the tool of choice to knock down the expression of specific genes. As a consequence, the concept of RNA having regulatory potential became widely accepted. Yet, there is more to come. Computational studies sugge... |
ABSTRACT Freshwater mussels, aquatic keystone species, are in global decline. Long life spans, sedentary lifestyles, and unique reproductive strategies involving obligate parasitic stages make unionid freshwater mussels particularly sensitive to environmental perturbations resulting from global climate change. A greate... |
By controlling optical loss in a multiple cavity laser, it is possible to sequentially switch the lasing wavelength with a mode suppression ratio greater than −35 dB. Our experiments use an antireflection coated semiconductor laser diode with optical feedback from Bragg gratings embedded in a single mode fiber. Residua... |

Motivated by recent advances in deep learning, a novel deep complex-valued convolutional neural network (CV-CNN)-based method is proposed for ground moving target indication (GMTI) in a multichannel synthetic aperture radar (SAR) system. The proposed method integrates the SAR-GMTI task into a blind inverse problem solv... |
Making educational materials freely available on the web can be seen as a noble enterprise in itself but as a way to address the call for people to become lifelong learners. The world is rapidly changing, requiring us to continuously update our knowledge and skills. A problem with this approach to lifelong learning is ... |
Since the advent of silicon device technologies, the scaling-down of device sizes has proceeded to within ready of atomic scale lengths. Consequently, it is necessary in some cases to reconsider device fabrication processes in the light of an understanding atomic scale phenomena. Since gate insulating films have been m... |
Several natural and artificial structures and systems are somehow optimized for performing specific functionalities. The structure and topology of cities are no exception, as it is critically important to ensure effective access to the several resources as well as overall mobility. The present work addresses the import... |
Competitive market forces and lower coordination costs are pushing large hierarchical organizations towards new organizational structures made of small, heterogeneous, project-oriented teams. These new organizations, however, lack the specialized knowledge created by functional units while working on several projects i... |
Plant growth and development depends on the activity of a continuously replenished pool of stem cells within the shoot apical meristem to supply cells for organogenesis. In Arabidopsis, the stem cell–specific protein CLAVATA3 (CLV3) acts cell nonautonomously to restrict the size of the stem cell population, but the hyp... |
The trend toward possible computers with interfaces to wireless network technologies is examined. The question of needed research and specification of hardware is discussed, the major challenges, such as services for the mobile user, mobile internetworking and adjusting to new technologies are described, and a listing ... |
We discuss here propagation of short electromagnetic pulses through dilute particulate random media consisting of scatterers in situations where the wave attenuation is dominated by scattering, rather than absorption. Examples of such phenomena include propagation of laser pulses through atmospheric clouds or through s... |

Then the digital reconstruction and comparison of LoD1 and LoD2 building models obtained with commercial packages and using different input data are presented. As input... |
Vitamin K1 (VK1) is an important cofactor of the electron-transfer chain in photosystem I (PS I), referred to as A1. The special properties of this quinone result from its unique interaction(s) with the protein surrounding. In particular, a single H-bond to neutral A1 was identified previously in the X-ray crystal stru... |
This paper reports the temperature dependency of Polarization Extinction Ratio (PER) in Polarization Maintaining Fiber (PMF) with LC/UPC connectors. Ten LC/UPC PMF patchcords were PER measured under 3 testing conditions: A, B and C. Test A, patchcords were coiled on hot plate for 5 loops with 3-cm inner diameter and 4-... |
BACKGROUND |
Organophosphorus (OP) pesticide urinary metabolite levels in a sample of farmworker children in North Carolina are documented and compared to national reference data. The relative importance of para-occupational, residential, and environment risk factors are delineated. |
METHODS |
Urine samples were collected from 60 farmworker children 1-6 years of age, and interviews were completed by their mothers. Urine samples were analyzed for the dialkylphosphate (DAP) metabolites of OP pesticides. Summed molar concentrations of the diethyl and dimethyl DAP metabolites provided summary measures. |
RESULTS |
The farmworker children had relatively high levels of OP pesticide urinary metabolites compared to national reference data; for example, participating children had higher geometric means for diethylphosphate (DEP), diethylthiophosphate (DETP), and the summed diethyl metabolites. However, analyses found no pattern of si... |
CONCLUSIONS |
Future research requires greater precision in sampling and measurement to determine the risk factors for pesticide exposure among farmworker children.Waveguide pattern formation in the organic nonlinear optical crystal by electron beam irradiation |
Organic nonlinear optical crystal 2-Adamanthylamino-5-nitropyridine (AANP) has attracted attention because of its large nonlinear susceptibility and the possibility of phase matching in the near-infrared wavelength region. To achieve high efficiency of propagation and modulation of light, it is necessary to fabricate o... |
This study reports carbon isotopic ratios (Δ(14)C and δ(13)C) of dissolved humic and fulvic acids in the Tokachi River system, northern Japan. These acids have a refractory feature and they represent the largest fraction of dissolved organic matter in aquatic environments. The acids were isolated using the XAD extracti... |

OBJECTIVE |
Data for clinical documentation and medical research are usually managed in separate systems. We developed, implemented and assessed a documentation system for myocardial scintigraphy (SPECT/CT-data) in order to integrate clinical and research documentation. This paper presents concept, implementation and evaluation of... |
METHODS |
We analyzed the documentation process for myocardial scintigraphy, especially for collecting medical history, symptoms and medication as well as stress and rest injection protocols. Corresponding electronic forms were implemented in our hospital information system (HIS) including plausibility checks to support correctn... |
RESULTS |
A single source system based on HIS-electronic documentation merges clinical and scientific documentation and thus avoids multiple documentation. Within nine months 495 patients were documented with our system by 8 physicians and 6 radiographers (466 medical history protocols, 466 stress and 414 rest injection protocol... |
CONCLUSION |
A single source system to collect routine and research data for myocardial scintigraphy is feasible in a real-world setting and can generate high-quality data through online plausibility checks.Buyer Alliances in Vertically Related Markets |

Abstract In the present work, the formation of ultrafine grained ferrite has been studied by applying suitable thermomechanical treatment. A high amount of deformation (∼80%) at varying strain rates (0·01–10 s−1) was applied in the temperature range of Ar3 to Ac3 followed by water quenching. This treatment resulted in ... |
Objective: Changes in the renin-angiotensin system (RAS), known for its critical role in the regulation of blood pressure and sodium homeostasis, may contribute to aging and age-related diseases. Here we characterized the RAS and kidney pathology in mice with genomic instability due to a defective nucleotide excision r... |
The (hetero)aromatic trifluoromethyl group is present in many biologically active molecules and is generally considered to be chemically stable.
