Dual state/rainfall correction via soil moisture assimilation for improved streamflow simulation: evaluation of a large-scale implementation with Soil Moisture Active Passive (SMAP) satellite data
Authors: Mao Yixin , Crow Wade T. , Nijssen Bart 
Published: February 2020

Abstract. Soil moisture (SM) measurements contain information about both pre-storm
hydrologic states and within-storm rainfall estimates, both of which are
required inputs for event-based streamflow simulations. In this study, an
existing dual state/rainfall correction system is extended and implemented
in the 605 000 km2 Arkansas–Red River basin with a semi-distributed
land surface model. The Soil Moisture Active Passive (SMAP) satellite
surface SM retrievals are assimilated to simultaneously correct antecedent SM states in the model and rainfall estimates from the Global Precipitation Measurement (GPM) mission. While the GPM rainfall is corrected slightly to moderately, especially for larger events, the correction is smaller than that reported in past studies due primarily to the improved baseline quality of the new GPM satellite product. In addition, rainfall correction is poorer in regions with dense biomass due to lower SMAP quality. Nevertheless, SMAP-based dual state/rainfall correction is shown to generally improve streamflow estimates, as shown by comparisons with streamflow observations across eight Arkansas–Red River sub-basins. However, more substantial streamflow correction is limited by significant systematic errors present in model-based streamflow estimates that are uncorrectable via standard data assimilation techniques aimed solely at zero-mean random errors. These findings suggest that more substantial streamflow correction will likely require better quality SM observations as well as future research efforts aimed at reducing systematic errors in hydrologic systems.

Published: February 2020

Now more than ever we live in a society saturated with technology and media. We are captured by the technology whirlwind such as the internet, instant messages, emails, and social media such as Twitter and Facebook. Technologies not only are changing the way people live, work, and interact with each other but also the way companies conduct their businesses. Social media no doubt is one of such technologies that enables companies to market their products and services in new and unique dimensions. Beyond marketing, social media is also changing the way human resource professionals recruit and select employees. Recruiting and selecting potential new employees using social media, is gaining popularity. There are even software programs that capitalize on the information available on social media sites to assist human resources professionals to source, screen, and track job applicants. Although there are many advantages in using social media networks to assist HR to select and filter job candidates, there are reasons for concerns. In this paper, we’ll examine the legal and ethical consequences of using social media in the area of human resource management. Keywords: Social Media, Facebook, Human Resources, Management.

El objetivo del estudio fue comparar el efecto del modelo de enseñanza en la mejora de la técnica individual en ambas piernas de jugadores de fútbol sub-10. Se analizaron a 12 jugadores que realizaron ocho sesiones con un modelo tradicional y ocho con un modelo moderno. Se midió: pase, control, conducción y golpeo de balón. El modelo tradicional mejora el pase y golpeo con la derecha y la conducción de balón con ambos pies, con diferencias significativas (p<.05) en el pase con derecha y la conducción de balón con ambas piernas. En el modelo innovador mejora el pase con pie dominante, la conducción lineal con ambos pies y el golpeo de balón a portería con ambos pies, con diferencias significativas en la conducción de balón con ambas piernas (p<.05). Por estos motivos, la mejora de la técnica individual de los jugadores necesita de la utilización modelos tradicionales e innovador.
The aim of the study was to compare the effect of the teaching model on the improvement of individual technique in both legs of soccer players sub-10. We analyzed 12 players who made eight sessions with a traditional model and eight with an innovative model. It was measured: pass, control, driving and hitting the ball. The traditional model improves the pass and hit with the right and the ball driving with both feet, with significant differences (p <.05) in the right pass and the ball driving with both legs. In the innovative model improves the pass with dominant foot, linear driving with both feet and hitting the ball on goal with both feet, with significant differences in the driving of the ball with both legs (p <.05). For these reasons, the improvement of the individual technique of the players requires the use of traditional and innovative models.

BackgroundHead and neck squamous cell carcinoma (HNSCC) is a malignant tumor with a strong tendency for metastasis and recurrence. Finding effective biomarkers for the early diagnosis of HNSCC is critical for the early treatment and prognosis of patients.MethodsRNA sequencing data including long non-coding RNAs (lncRNAs), messenger RNA (mRNAs) and microRNAs (miRNAs) of 141 HNSCC and 44 adjacent normal tissues were obtained from the TCGA. Differentially expressed genes were analyzed using the R package DESeq. GO terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted. A competing endogenous RNAs (ceRNA) network was constructed. The most differentially expressed genes in the main ceRNA network were chosen for nasopharyngeal carcinoma (NPC) cell lines and NPEC2 Bmi-1 cell line verification. A receiver operating characteristic (ROC) curve was constructed for 141 specimens of HNSCC tissues from 44 control samples.ResultsIn our study, 79 HNSCC-associated abnormally expressed lncRNAs , 86 abnormally expressed miRNAs and 324 abnormally expressed mRNAs were identified. The public microarray results showed that LINC00958 and HOXC13-AS expression levels were upregulated in HNSCC tissues compared with the adjacent normal tissues in this study (p < 0.0001). LINC00958 and HOXC13-AS expression levels in NPC cell lines were higher than those in the NPEC2 Bmi-1 cell line (p < 0.05). The results showed that the area under the ROC curve (AUC) of LINC00958 reached up to 0.906 at a cutoff value of 7.96, with a sensitivity and specificity of 80.85% and 90.91%, respectively. The AUC of HOXC13-AS reached up to 0.898 at a cutoff value of 0.695, with sensitivity and specificity values of 86.23% and 83.78%, respectively.ConclusionThe current study indicates that LINC00958 and HOXC13-AS are new candidate diagnostic biomarkers for HNSCC patients.
Analysis of Lipids: Triacylglycerols, Phospholipids, Fatty Acids, and Others
Authors: Byrdwell William C. 
Published: February 2020

AbstractLipids comprise large and disparate classes of molecules having very different overall polarities, but the one characteristic they typically have in common is a nonpolar hydrocarbon chain that is hydrophobic in nature. The characteristics of each class of lipid dictate the most appropriate tool and approach for analysis. Since many PLs are inherently charged, the polar head group makes them ideally amenable to soft ionization by electrospray ionization (ESI) coupled to MS. In contrast, triacylglycerols (TAGs) are large neutral molecules that are not easily directly ionized by electrospray ionization mass spectrometry (ESI‐MS), and formation of adducts is necessary. Atmospheric pressure chemical ionization (APCI) and atmospheric pressure photoionization (APPI) both readily ionize neutral molecules such as TAGs and sterols. This article will outline the characteristics of each class of lipid, and how these affect the choice for the most appropriate tool for their analysis, including special steps and considerations to be taken into account to optimize analysis of each class. Emphasis will be given to neutral lipids (i.e. TAGs), which are the major components of many edible lipid mixtures. The article will also focus on the approaches necessary to derive the desired structural information from lipids. Many of the principles fundamental to lipid analysis in foods and edible oils were developed for analysis of biological samples, but are directly applicable to fats and oils. This article is intended to serve as a guide for decision‐making, by discussing the strengths and weaknesses and the benefits and shortcomings of the available options for detailed lipid analysis.

Published: February 2020

Melanoma is an unpredictable, highly metastatic malignancy, and treatment of advanced melanoma remains challenging. Novel molecular markers based on the alterations in gene expression and the molecular pathways activated or deactivated during melanoma progression are needed for predicting the course of the disease already in primary tumors and for providing new targets for therapy. Here, we sought to identify genes whose expression in primary melanomas correlate with patient disease‐specific survival using global gene expression profiling. Many of the identified potential markers of poor prognosis were associated with the epithelial–mesenchymal transition, extracellular matrix formation, and angiogenesis. We studied further the significance of one of the genes, prolyl 4‐hydroxylase subunit alpha 1 (P4HA1), in melanoma progression. P4HA1 depletion in melanoma cells reduced cell adhesion, invasion, and viability in vitro. In melanoma xenograft assays, we found that P4HA1 knockdown reduced melanoma tumor invasion as well as the deposition of collagens, particularly type IV collagen, in the interstitial extracellular matrix and in the basement membranes of tumor blood vessels, leading to vessel wall rupture and hemorrhages. Further, P4HA1 knockdown reduced the secretion of collagen triple helix repeat containing 1 (CTHRC1), an important mediator of melanoma cell migration and invasion, in vitro and its deposition around tumor blood vessels in vivo. Taken together, P4HA1 is an interesting potential prognostic marker and therapeutic target in primary melanomas, influencing many aspects of melanoma tumor progression.

Published: February 2020

AbstractAqueous Zn batteries have drawn tremendous attention for their several advantages. However, the challenges of Zn anodes such as the corrosion and ZnO densification have compromised their application in rechargeable Zn‐based batteries. In this paper, a straightforward strategy is employed to facilitate the uniform Zn stripping/plating of the Zn anode through using a ZrO2 coating layer, which contributes to the controllable nucleation sites for Zn2+ and fast Zn2+ transportation through the favorable Maxwell–Wagner polarization. As a result, the low polarization (24 mV at 0.25 mA cm−2), high Coulombic efficiency (99.36% at 20 mA cm−2), and long cycle life (over 3800 h at 0.25 mA cm−2) can be obtained for the ZrO2‐coated Zn anode. It is believed that the ZrO2 coating layer can also act as an inert physical barrier to decrease the contact of the anode and electrolyte, thus reducing both the Zn corrosion and formation of ZnO densification, and then improve the reversibility of Zn anode. The results demonstrated in this work provide an appealing strategy for the future development of rechargeable Zn‐based batteries.

Published: February 2020

AbstractLi‐rich layered oxides are promising cathode materials for next‐generation Li‐ion batteries because of their extraordinary specific capacity. However, the activation process of the key active component Li2MnO3 in Li‐rich materials is kinetically slow, and the complex phase transformation with electrode/electrolyte side reactions causes fast capacity/voltage fading. Herein, a simple thermal treatment strategy is reported to simultaneously tackle these challenges. The introduction of a urea thermal treatment on Li‐rich material Li1.87Mn0.94Ni0.19O3 leads to oxygen deficiencies and partially reduced Mn ions on the oxide surface for activating the Li‐rich phase. In situ synchrotron study confirms that the urea‐treated cathode shows much faster Li extraction from both Li and transition metal layers with less oxygen evolution upon charging than that of untreated counterparts. Moreover, the decomposition products of urea during thermal treatment subsequently deposit on the surface of cathode material, leading to a unique passivation layer against side reactions between electrode and electrolyte. Soft X‐ray absorption spectroscopy reveals the structural evolution mechanism with a significantly suppressed dissolution of Mn species over cycling measurement. The urea‐treated Li1.87Mn0.94Ni0.19O3 shows accelerated activation kinetics to reach high capacity of 270 mA h g–1 and demonstrates excellent capacity retention of 98.49% over 300 cycles with slower voltage decay.

AbstractLayered transition metal oxides have drawn much attention as a promising candidate cathode material for sodium‐ion batteries. However, their performance degradation originating from strains and lattice phase transitions remains a critical challenge. Herein, a high‐concentration Zn‐substituted NaxMnO2 cathode with strongly suppressed P2–O2 transition is investigated, which exhibits a volume change as low as 1.0% in the charge/discharge process. Such ultralow strain characteristics ensure a stable host for sodium ion storage, which significantly improves the cycling stability and rate capability of the cathode material. Also, the strong coupling between the highly reversible capacity and the doping content of Zn in NaxMnO2 is investigated. It is suggested that a reversible anionic redox reaction can be effectively triggered by Zn ions and is also highly dependent on the Zn content. Such an ion doping strategy could shed light on the design and construction of stable and high‐capacity sodium ion host.

Published: February 2020

AbstractMetal halide perovskites have recently attracted enormous attention for photovoltaic applications due to their superior optical and electrical properties. Lead (Pb) halide perovskites stand out among this material series, with a power conversion efficiency (PCE) over 25%. According to the Shockley–Queisser (SQ) limit, lead halide perovskites typically exhibit bandgaps that are not within the optimal range for single‐junction solar cells. Partial or complete replacement of lead with tin (Sn) is gaining increasing research interest, due to the promise of further narrowing the bandgaps. This enables ideal solar utilization for single‐junction solar cells as well as the construction of all‐perovskite tandem solar cells. In addition, the usage of Sn provides a path to the fabrication of lead‐free or Pb‐reduced perovskite solar cells (PSCs). Recent progress in addressing the challenges of fabricating efficient Sn halide and mixed lead–tin (Pb–Sn) halide PSCs is summarized herein. Mixed Pb–Sn halide perovskites hold promise not only for higher efficiency and more stable single‐junction solar cells but also for efficient all‐perovskite monolithic tandem solar cells.

Published: February 2020

AbstractTransparent conducting electrodes (TCE) using metal (Cu and Ag) nanowires (NWs) have received great attention, due to their high conductivity, flexibility, and transparency, as alternatives for conventional conductive oxides. Hybridizing with semiconductor, the metal NWs TCE allows for transparent, flexible but high‐performance functional devices such as logical circuit and active device components. However, the electrical performance of hybrid metal NWs/organic semiconductor is still low compared to the hybrid with inorganic semiconductor, such as a‐Si, while the inorganic semiconductors have the limitation of flexibility and transparency. Ultrathin silicon nanomembranes (Si NMs) with thickness in the range of 10–300 nm offer new opportunities in flexible, transparent applications with enhanced electrical performance. Herein, integration strategy of metal (Cu and Ag) NWs with ultrathin (≈200 nm) Si NMs is presented. Vacuum filtering and hot‐rolling process of metal NWs to various inorganic semiconductors and its oxide and nitride substrates (e.g., Si, SiO2, SiNx, and a‐IGZO) yields high transfer rates (≈90% in all cases), which acts as a conductive, ohmic contacted, and transparent electrode. Optic and temperature sensors are demonstrated and the transparent and versatile functional uses of integrated layers of metal NWs and semiconductor substrates, using the transfer method are verified.
Noncationic Material Design for Nucleic Acid Delivery

Published: February 2020

AbstractNucleic acid delivery provides effective options to control intracellular gene expression and protein production. Efficient delivery of nucleic acid typically requires delivery vehicles to facilitate the entry of nucleic acid into cells. Among nonviral delivery vehicles, cationic materials are favored because of their high loading capacity for nucleic acids and prominent cellular uptake efficiency through electrostatic interactions. However, cationic moieties at high dosage tend to induce severe cytotoxicity due to interference with cell membrane integrity. In contrast, noncationic materials present alternative delivery approaches with less safety concerns than cationic materials. In this Progress Report, principles of noncationic material design for nucleic acid delivery are discussed. Examples of such noncationic platforms are highlighted, including complexation or conjugation with nucleic acids and self‐assembled nucleic acid structures.

Published: February 2020

AbstractWearable sensors promise to transform human understanding of body state. However, despite many wearable sensor modalities that exist, few demonstrate the raw capabilities required for many emerging healthcare applications—passivity (and microelectronics‐free), wireless readout, long‐term operation, and specificity. Hydrogel‐interlayer radio‐frequency resonators are demonstrated as a versatile platform for passive and wireless biosensing. Fabricated using a simple vinyl cutter, the base resonator is composed of unanchored, broad‐side coupled coils interceded by multifunctional hydrogels—such resonators are tuned to be sensitive to specific analytical or physical signals by modifying hydrogel composition. These resonators are transformed into near‐field communication (NFC) sensor circuits through the simple attachment of an LED. These enable direct quantification of sensor state by cellphone and eye with no specialized electronics required. Resonator arrays are finally fused with silicone to form soft, wireless sensor skins that enable co‐readout of analytical to physical signals while molded to human subjects. Such low‐cost, accessible platforms can integrate with environments in transformative ways, enabling new applications in wireless sensing.
