Trampantojos de hormigón. Simultaneidad ilimitada, memoria y acontecimiento arquitectónico
Authors: Salazar Valenzuela Mauricio 
Published: October 2019

<p>Los edificios contemporáneos en hormigón visto, de la Biblioteca Nacional de Qatar de OMA y la biblioteca del Centro Cultural Universitario Rogelio Salmona, parecieran formarse como los dispositivos de ilusión espacial, que se desarrollaron instrumentalmente en Europa durante el siglo XVII, con esto, desvelando cómo subrepticiamente en la contemporaneidad habitan de manera simultánea, otros tiempos, procedimientos y arquitecturas, que se han sofisticado y reinventado mediante intrépidas configuraciones espaciales y estructurales, que animan al visitante a moverse, mientras transita por manipulaciones perspectivas de escala y afectación urbana. Estos proyectos así como son un trampantojo real –in situ– que se puede recorrer y habitar, también son trampantojos mnemónicos de arquitecturas, por las asociaciones, equivalencias y contrastes que generan con otras arquitecturas: con esto, revelan valores arquitectónicos contemporáneos, remplazando lo literal por lo literario, con ello entrando y trasgrediendo el ‘interior’ de las ‘reglas’ de las arquitecturas emuladas, y así actualizándolas en la contemporaneidad. De igual manera, destacan la importancia del material –hormigón visto-, y la materialidad de los elementos que los constituyen, ya que hacen que realidad e ilusión, se constituyen en la estructura que permite trasformar el acontecimiento arquitectónico en materia, y donde quien habita dichas arquitecturas se siente a la vez envuelto por la realidad y liberado de esta. La arquitectura se vuelve una visión real e ideal de lo imposible.</p><p><em><br /></em></p>

Published: October 2019

Introduction:
Chronic infections after a total hip arthroplasty (THA) are a devastating complication and are usually treated by a complete revision of components. Selective revision, with preservation of well-fixed components, has been previously reported. We did a systematic review to report on success rates of selective revision in chronic infections after THA.

Methods:
PubMed, Web of Science, and the Cochrane Database were systematically searched for studies reporting on partial-retaining revision for chronically infected THA. These were reviewed to determine success rates based on component revised, as well as infectious organism.

Results:
Nine studies reported on 134 patients. The majority of the patients underwent femoral-retaining procedures (118), and the rest of the patients underwent acetabular-retaining procedures (16). Average follow-up was 60.56 months, and the success rates were 80% for femoral revision, 90.43% for acetabular revision, and overall success rate was 89.41%.

Discussion:
In select patients, retainment of well-fixed components in chronically infected THA may be considered. Although reported success rates are high, and comparable with complete revision arthroplasty in cases of chronic infections, the quality of the studies included is poor. The studies lacked sufficient internal validity, sample size, methodological consistency, and standardization of protocols and outcomes.

As concepções schopenhauerianas de filosofia
Authors: Damasceno Francisco William Mendes 
Published: October 2019

Nosso texto pretende mostrar que está presente no pensamento schopenhaueriano, para além da sua definição “canônica”, uma outra concepção de filosofia que torna possível pensarmos uma filosofia prática de uma perspectiva propriamente empírica. Schopenhauer frequentemente define a filosofia como teoria metafísica de caráter contemplativo que abdica de toda normatividade. Contudo, encontramos uma outra noção menos elevada e mais próxima da dimensão prática da vida, orientada por uma perspectiva mais empírica e de caráter eudemonológico. Essa outra noção de filosofia torna possível pensar uma ética não descritiva, que permanece alheia à normatividade moral, mas considera máximas que servem como recurso estratégico para uma vida mais suportável.
Enhanced glycosylation of an S‐layer protein enables a psychrophilic methanogenic archaeon to adapt to elevated temperatures in abundant substrates

Published: October 2019

Adaptation to higher temperatures would increase the environmental competitiveness of psychrophiles, organisms that thrive in low‐temperature environments. Methanolobus psychrophilus, a cold wetland methanogen, ‘evolved’ as a mesophile, growing optimally at 30 °C after subculturings, and cells grown with ample substrates exhibited higher integrity. Here, we investigated N‐glycosylation of S‐layer proteins, the major archaeal envelope component, with respect to mesophilic adaptation. Lectin affinity enriched a glycoprotein in cells grown at 30 °C under ample substrate availability, which was identified as the S‐layer protein Mpsy_1486. Four N‐glycosylation sites were identified on Mpsy_1486, which exhibited different glycosylation profiles, with N94 only found in cells cultured at 30 °C. An N‐linked glycosylation inhibitor, tunicamycin, reduced glycosylation levels of Mpsy_1486 and growth at 30 °C, thus establishing a link between S‐layer protein glycosylation and higher temperature adaptation of the psychrophilic archaeon M. psychrophilus.
Regulation of the thiamine pyrophosphate (TPP)‐sensing riboswitch in NMT1 mRNA from Neurospora crassa
Authors: Gong Sha , Du Chengyi , Wang Yanli 
Published: October 2019

The expression of Neurospora crassa NMT1 involved in thiamine pyrophosphate (TPP) metabolism is regulated at the level of mRNA splicing by a TPP‐sensing riboswitch within the precursor NMT1 mRNA. Here, using the systematic helix‐based computational method, we investigated the regulation of this riboswitch. We find that the function of the riboswitch does not depend on the transcription process. Whether TPP is present or not, the riboswitch predominately folds into the ON state, while the OFF state aptamer structure does not appear during transcription. Since the transition from the ON state to the aptamer structure is extremely slow, TPP may interact with the RNA before full formation of the aptamer structure, promoting the switch flipping. The potential to fully form helix P0 of the ON state is necessary to restore ligand‐dependent gene control by the riboswitch.

Published: October 2019

Colorectal cancer (CRC) is the third most common tumor worldwide, and recent epidemiological studies have indicated that obesity contributes to the morbidity and mortality of CRC. Furthermore, obesity‐related adipokines have been shown to be closely related to the incidence of CRC, but the underlying mechanisms are unclear. Here, we investigated the effects of high‐fat diet‐induced adipokines and cytokines on the development of CRC in vitro and in vivo. For the in vivo assays, we divided 2‐week‐old C57BL/6J‐ApcMin/J male mice into three groups: normal‐fat diet (ND), high‐fat and high‐sugar feed (HFHS), and high‐fat and low‐sugar feed (HFLS). After 1 week, all mice were injected with 20 mg·kg−1 1,2‐dimethylhydrazine once weekly for 10 consecutive weeks. Body weight, liver weight, epididymal fat weight and blood glucose levels were greatly increased in HFHS and HFLS groups compared with the ND group, and the expression levels of some adipokines and cytokines were obviously higher in HFHS or HFLS mice compared with ND mice. For the in vitro assays, HCT116 CRC cells were treated with sera of ND, HFHS or HFLS groups, or serum‐free media as a negative control. We observed that sera derived from HFHS or HFLS mice that contain excess adipokines and cytokines promoted the proliferation, migration and invasion of HCT116 cells compared with the ND sera‐conditioned medium or serum‐free medium group. Therefore, high‐fat diet‐induced adipokines and cytokines may promote the progression of CRC in vivo and in vitro.
Superimposed Training and Blind Channel Estimation
Authors: Jiménez Juan C. Estrada , García M. Julia Fernández‐Getino , Méndez‐Romero Diego 
Published: October 2019

AbstractSuperimposed training (ST) is one of the most promising channel estimation techniques, which provides an even better performance than pilot‐symbol‐assisted modulation (PSAM). ST techniques superimpose pilot symbols over the data signal, so that pilots and data share the same resources, thus avoiding loss in data rate. This feature makes them very attractive for future 5G systems where high data rates are expected. ST techniques suffer from interference between pilots and data, which requires more sophisticated channel estimation and data detection algorithms. Apart from pilot‐based strategies, channel estimation can be accomplished without relying on training signals. Then, blind channel estimation can obtain channel information based on the analysis of the received signal. Blind techniques, similarly to ST schemes, do not waste resources for channel estimation, but their performance is not as precise as pilot‐based schemes. Nowadays, there is a great interest in ST and blind channel estimation due to its spectral efficiency.

Published: October 2019

AbstractDriven by the ever‐increasing demand for higher user data rates and greater network capacity, the exploration of the millimeter‐wave (mmWave) spectrum is considered a promising technique in the upcoming fifth‐generation (5G) mobile communication systems. As one of the key components in 5G mmWave systems, antenna designs are facing enormous challenges and therefore attracting much research attention. Several mmWave antenna design parameters gain higher priorities, including bandwidth, gain, polarization, radiation direction, fabrication techniques, and profile, which need further investigation and concern in the design process. Important techniques and research interests are thus discussed in detail, including antenna elements, single‐beam and multibeam arrays, antennas for mobile terminals, and antenna‐in‐package solutions.

D2D
Authors: Liu Xilong , Ansari Nirwan 
Published: October 2019

Abstract
Device‐to‐device (D2D) communications, which facilitates direct transmissions between proximate devices, is one of the key enabling technologies for 5G communications. A mobile device commonly carries a limited energy supply, and it is thus critical to develop energy‐efficient D2D communications. This article provides a discourse on how to improve energy efficiency in D2D communications via proper bandwidth and power allocation and how to leverage green energy harvesting and dual‐battery architecture to enhance self‐sustainability of devices. With the introduction of green energy–powered devices, a green relay assignment scheme is used to leverage the green relay devices to assist dual‐hop D2D communications. This article also elicits the important role of mobile edge computing (MEC) in enabling D2D communications in which cloudlets in MEC may provide essential computing resources for the cellular base stations to jointly consider the channel state information among the devices, multihop routing path and bandwidth allocation to efficiently facilitate D2D communications.

ObjectiveThe accurate and efficient collection and documentation of disease activity measures (DAMs) is critical to improve clinical care and outcomes research in rheumatoid arthritis (RA). This study evaluated the performance of an automated process to extract DAMs from medical notes in the electronic health record (EHR).MethodsAn automated text processing system was developed to extract the Disease Activity Score for 28 joints (DAS28) and its clinical and laboratory elements from the Veterans Affairs EHR for patients enrolled in the Veterans Affairs Rheumatoid Arthritis (VARA) registry. After automated text processing derivation, data accuracy was assessed by comparing the automated text processing system and manual extraction with gold standard chart review in a separate validation phase.ResultsIn the validation phase, 1569 notes from 596 patients at 3 sites were evaluated, with 75 (6%) notes detected only by automated text processing, 85 (5%) detected only by manual extraction, and 1408 (90%) detected by both methods. The accuracy of automated text processing ranged from 90.7% to 96.7% and the accuracy of manual extraction ranged from 91.3% to 95.0% for the different clinical and laboratory elements. The accuracy of the two methods to calculate the DAS28 was 78.1% for automated text processing and 78.3% for manual extraction.ConclusionThe automated text processing approach is highly efficient and performed as well as the manual extraction approach. This advance has the potential for significant improvements in the collection, documentation, and extraction of these data to support clinical practice and outcomes research relevant to RA as well as the potential for broader application to other health conditions.

Published: October 2019

AbstractHighly efficient orange–red/red thermally activated delayed fluorescence (TADF) materials have been rarely reported due to the restriction of their molecular design in the energy gap law. An effective strategy is to use large rigid planar units and strong intramolecular charge transfer for synthesizing efficient long‐wavelength TADF materials. Three novel orange–red to red TADF materials are obtained using a large rigid planar dibenzo[a,c]phenazine (BP) acceptor core and different numbers of strong electron‐donating phenoxazine (PXZ) moieties, namely 1PXZ‐BP, 2PXZ‐BP, and 3PXZ‐BP. The increase in the number of PXZ units red‐shifts the emission from 602 to 682 nm in solution. Moreover, these emitters are endowed with high electroluminescence performance due to small singlet–triplet energy difference (ΔEST), fast radiative rate, and high photoluminescence quantum yields. 1PXZ‐BP‐based orange–red organic light‐emitting diodes (OLEDs) achieve an excellent external quantum efficiency of 26.3%, which is one of the highest efficiencies reported for orange–red TADF OLEDs.

AbstractBulk heterojunction (BHJ) nonfullerene organic solar cells prepared from sequentially deposited donor and acceptor layers (sq‐BHJ) have recently been shown to be highly efficient, environmentally friendly, and compatible with large area and roll‐to‐roll fabrication. However, the related photophysics at donor‐acceptor interface and the vertical heterogeneity of donor‐acceptor distribution, critical for exciton dissociation and device performance, have been largely unexplored. Herein, steady‐state and time‐resolved optical and electrical techniques are employed to characterize the interfacial trap states. Correlating with the luminescent efficiency of interfacial states and its nonradiative recombination, interfacial trap states are characterized to be about 40% more populated in the sq‐BHJ devices than the as‐cast BHJ (c‐BHJ), which probably limits the device voltage output. Cross‐sectional energy‐dispersive X‐ray spectroscopy and ultraviolet photoemission spectroscopy depth profiling directly visualize the donor–acceptor vertical stratification with a precision of 1–2 nm. From the proposed “needle” model, the high exciton dissociation efficiency is rationalized. This study highlights the promise of sequential deposition to fabricate efficient solar cells, and points toward improving the voltage output and overall device performance via eliminating interfacial trap states.
Proposing the solar‐wind energy flux hypothesis as a driver of inter‐annual variation in tropical tree reproductive effort
Authors: Hogan J. Aaron , Nytch Christopher J. , Bithorn John E. , Zimmerman Jess K. 
Published: October 2019

PremiseThe El Niño Southern Oscillation (ENSO) affects tropical environmental conditions, potentially altering ecosystem function as El Niño events interact with longer‐term climate change. Anomalously warm equatorial Pacific Ocean temperatures affect rainfall and temperature throughout the tropics and coincide with altered leaf flush phenology and increased fruit production in wet tropical forests; however, the understanding of mechanisms underlying this pattern is limited. There is evidence that increases in tropical tree reproduction anticipate El Niño onset, motivating the continued search for a global driver of tropical angiosperm reproduction. We present the solar‐wind energy flux hypothesis: that physical energy influx to the Earth's upper atmosphere and magnetosphere, generated by a positive anomaly in the solar wind preceding El Niño development, cues tropical trees to increase resource allocation to reproduction.MethodsWe test this hypothesis using 19 years of data from Luquillo, Puerto Rico, correlating them with measures of solar‐wind energy.ResultsFrom 1994 to 2013, the solar‐wind energy flux into Earth's magnetosphere (Ein) was more strongly correlated with the number of species fruiting and flowering than the Niño 3.4 climate index, despite Niño 3.4 being previously identified as a driver of interannual increases in reproduction.ConclusionsChanges in the global magnetosphere and thermosphere conditions from increased solar‐wind energy affect global atmospheric pressure and circulation patterns, principally by weakening the Walker circulation. We discuss the idea that these changes cue interannual increases in tropical tree reproduction and act through an unidentified mechanism that anticipates and synchronizes the reproductive output of the tropical trees with El Niño.

AbstractObjectivesThis study investigates bone density across the life course among Bolivian Tsimane and Ecuadorian Shuar of Amazonia. Both groups are rural, high‐fertility forager‐horticulturalists, with high lifetime physical activity levels. We test whether Tsimane and Shuar bone density patterns are different from each other, and if both groups are characterized by lower osteoporosis risk compared to U.S. references.MethodsAnthropometric and calcaneal bone density data, obtained via quantitative ultrasonometry (QUS), were collected from 678 Tsimane and 235 Shuar (13–92 years old). Population and sex differences in QUS values (estimated bone mineral density, speed of sound, broadband ultrasound attenuation) by age group were assessed using Mann–Whitney U tests. Age‐related change and age at peak QUS value were determined using polynomial regressions. One‐way analyses of covariance assessed population‐level differences in QUS values by age group adjusting for body mass index. Participants aged 50+ years at elevated osteoporosis risk were identified using a T score < −1.8; binomial tests assessed risk compared to U.S. references.ResultsShuar males and females <50 years old have QUS values 3–36% higher than Tsimane, with differences evident in adolescence. Among Tsimane and Shuar, 49 and 23% of participants aged 50+ years old, respectively, are at high risk for osteoporosis, compared to 34% of Americans; Shuar osteoporosis risk is comparable to Americans, while Tsimane risk is elevated.ConclusionsDisparate patterns in QUS values are documented for Tsimane and Shuar, with pronounced differences early in life. Potential explanations for differences include gene–environment interactions and/or degree of market integration, which influences diet, activity profiles, pathogen exposures, and other lifestyle covariates. As Tsimane osteoporosis risk is greater than in the United States, findings point to alternative risk factors for low bone density that are not readily discernible in industrialized populations.
Fishing facts and phishing fictions on K'gari (Fraser Island): Archaeological discourse in a post‐truth world
Authors: MEYRIC COSTELLO ANDREW JAMES 
Published: October 2019

ABSTRACTAs a discipline, archaeology must explore ways to present Indigenous and scientific interpretations of the past, employing mechanisms that are effective and relevant to contemporary Indigenous people, and which communicate values for the future that are shared by Indigenous and non‐Indigenous peoples alike. Inclusive archaeological discourse and cultural heritage management can amplify First Nations voices and contribute to the public debate on the contemporary understanding of Australia's past. In developing new ways to explore archaeological relevance to First Nations people, but also working to prevent the loss of intellectual property, archaeologists in partnership with First Nations people can forge new ways to research and communicate ideas and scientific data. The contemporary story of K'gari (Fraser Island, south‐east Queensland) and the effective harnessing by Butchulla people of modern media strategies to assert their ongoing custodial and cultural rights and diminish colonial constructs imposed upon them is a powerful example of innovative resilience and positive social change.
