AbstractAimEvaluate sex differences in procedural net adverse clinical events and long‐term outcomes following rotational atherectomy (RA).Methods and ResultsFrom August 2010 to 2016, 765 consecutive patients undergoing RA PCI were followed up for a median of 4.7 years. 285 (37%) of subjects were female. Women were older (mean 76 years vs. 72 years; p < .001) and had more urgent procedures (64.6 vs. 47.3%; p < .001). Females received fewer radial procedures (75.1 vs. 85.1%; p < .001) and less intravascular imaging guidance (16.8 vs. 25.0%; p = .008). After propensity score adjustment, the primary endpoint of net adverse cardiac events (net adverse clinical events: all‐cause death, myocardial infarction, stroke, target vessel revascularization plus any procedural complication) occurred more often in female patients (15.1 vs. 9.0%; adjusted OR 1.81 95% CI 1.04–3.13; p = .037). This was driven by an increased risk of procedural complications rather than procedural major adverse cardiac events (MACE). Specifically, women were more likely to experience coronary dissection (4.6 vs. 1.3%; p = .008), cardiac tamponade (2.1 vs. 0.4%; p = .046) and significant bleeding (BARC ≥2: 5.3 vs. 2.3). Despite this, overall MACE‐free survival was similar between males and females (adjusted HR 1.03; 95% CI 0.80–1.34; p = .81). Procedural complications during RA were associated with almost double the incidence of MACE at long‐term follow‐up (HR 1.92; 95% CI 1.34–2.77; p < .001).ConclusionWomen may be at greater risk of procedural complications following rotational atherectomy. These include periprocedural bleeding episodes and coronary perforation leading to cardiac tamponade. Despite this, the adjusted overall long‐term survival free of major adverse cardiac events was similar between males and females.

AbstractBackground and objectivesPurple wheat is relatively rich in anthocyanin and phenolic acid compounds that have demonstrated positive physiological effects in humans. This study was intended to develop purple wheat (PW) food prototypes with potential to impact metabolic markers and health conditions. Several products including PW bars, crackers, bread, pancake, and porridge were developed and evaluated based on their nutrient content, anthocyanin composition, and antioxidant properties.FindingsThe products substantially varied in their nutrient contents with protein being high in PW bread, pancake, and porridge (16.5%–18.8%) and intermediate in PW bars and crackers (8.9%–11%–6%). The bran‐enriched PW products and whole wheat pancake were rich in dietary fiber (16.4%–32.6%). The bran was added to boost levels of anthocyanin and dietary fiber in products. The crackers and bars had the highest anthocyanin content (55.9 and 41.7 µg/g, respectively) and were selected over other products for antioxidant testing in vitro. These two products strongly inhibited ABTS, DPPH, and peroxyl radical activities pointing to potential to influence metabolic markers and general health.ConclusionsThe PW bars and crackers hold promise as functional foods based on their contents of polyphenols and dietary fiber and antioxidant properties.Significance and noveltyThe study provides useful information about the innovative PW bars and crackers for further human studies.

Published: July 2019

AbstractDirectly linked to promote strong intramolecular interactions, donor–acceptor dyads and a donor–acceptor–donor triad featuring zinc phthalocyanine (ZnPc) as electron donor and perylenediimide (PDI) as electron acceptor have been synthesized and characterized. Owing to complementary absorption features of the entities, improved light absorption was witnessed in these conjugates. The optimized geometry and electronic structures showed the majority of the highest occupied molecular orbital (HOMO) on the ZnPc entity, whereas the lowest unoccupied molecular orbital (LUMO) was on the PDI entity, suggesting that the charge‐separated states would be ZnPc+–PDI.−. The electrochemical and free‐energy calculations suggested exothermic energy and/or electron transfer processes via the singlet states of PDI or ZnPc entities depending on the excitation wavelength of the laser used. The measured rates using femtosecond pump‐probe spectroscopy coupled with global analysis of transient data revealed ultrafast energy transfer from 1PDI* to ZnPc followed by charge separation. However, when ZnPc was selectively excited, only electron transfer was witnessed wherein the time constants for forward and reverse electron transfer processes followed Marcus predictions. The absorption in a wide section of the solar spectrum and the ultrafast charge separation suggest the usefulness of these systems as good photosynthetic models.
Soluble and Planar 2,9‐Diazaperopyrenes through Reductive Aromatization of Perylene Diimides: Tunable Emission and Aggregation Behaviors

Published: July 2019

AbstractReductive aromatization of perylene diimides with acid anhydrides in the presence of Mn or Zn metals provides soluble and planar 2,9‐diazaperopyrenes with ester groups at 1,3,8,10‐positions. The pivaloxy groups at the peripheral positions can be transformed into a variety of aryl groups through nickel‐catalyzed cross‐coupling of ester groups. Emission colors of diazaperopyrenes are tunable by the peripheral substituents. The peripheral substituents also affect the aggregation behaviors of 2,9‐diazaperopyrenes in the solution and solid states.

Fast Binary Embeddings and Quantized Compressed Sensing with Structured Matrices
Authors: Huynh Thang , Saab Rayan 
Published: July 2019

This paper deals with two related problems, namely distance‐preserving binary embeddings and quantization for compressed sensing. First, we propose fast methods to replace points from a subset Χ ⊂ ℝn, associated with the euclidean metric, with points in the cube {±1}m, and we associate the cube with a pseudometric that approximates euclidean distance among points in Χ. Our methods rely on quantizing fast Johnson‐Lindenstrauss embeddings based on bounded orthonormal systems and partial circulant ensembles, both of which admit fast transforms. Our quantization methods utilize noise shaping, and include sigma‐delta schemes and distributed noise‐shaping schemes. The resulting approximation errors decay polynomially and exponentially fast in m, depending on the embedding method. This dramatically outperforms the current decay rates associated with binary embeddings and Hamming distances. Additionally, it is the first such binary embedding result that applies to fast Johnson‐Lindenstrauss maps while preserving ℓ2 norms.Second, we again consider noise‐shaping schemes, albeit this time to quantize compressed sensing measurements arising from bounded orthonormal ensembles and partial circulant matrices. We show that these methods yield a reconstruction error that again decays with the number of measurements (and bits), when using convex optimization for reconstruction. Specifically, for sigma‐delta schemes, the error decays polynomially in the number of measurements, and it decays exponentially for distributed noise‐shaping schemes based on beta encoding. These results are near optimal and the first of their kind dealing with bounded orthonormal systems. © 2019 Wiley Periodicals, Inc.

Published: July 2019

SummaryLow‐power wide area networks (LP‐WANs) protocols are considered options to meet the requirements of Internet of Things (IoT) solutions that need long‐range communication with low power consumption. Few studies intended to evaluate the performance of the same class of protocols coexisting in the same environment and with mobility support. This paper explores the technical characteristics of Sigfox and long‐range (LoRa) protocols and presents a performance evaluation study considering mobility scenarios. The experiments were performed in real environments. Then, two prototypes for LoRa and Sigfox equipped with Global Positioning System (GPS) were created. Quantitative and qualitative performance metrics were also proposed for this study. The results showed that the coexistence between these protocols has soft impact on the performance presented. Because of the movement, the effects of Doppler, multipath, and signal fading hardly affect the performance of both protocols.

AbstractAs a widely distributed species along the Irtysh River, Phoxinus phoxinus ujmonensis (Kaschtschenko, 1899) was used as a model to investigate genetic diversity and population structure as well as the influence of environmental factors on population genetics. In this study, we specifically developed 12 polymorphic microsatellite loci. The analysis of microsatellite and mtDNA markers revealed a high and a moderate genetic diversity across seven populations, respectively. Moderate differentiation was also detected among several populations, indicating the impact of habitat fragmentation and divergence. The absence of isolation by distance implied an extensive gene flow, while the presence of isolation by adaptation implied that these populations might be in the process of adapting to divergent habitats. Correlation analysis showed that abiotic factors like dissolved oxygen, pH, total dissolved solids, and conductivity in water as well as biotic factors like plankton diversity and fish species diversity had impact on genetic diversity and divergence in P. phoxinus ujmonensis populations. The results of this study will provide an insight into the effect of environmental factors on genetic diversity and contribute to the study of population genetics of sympatric species.
Surface Plasmon Resonance Coupled with Potential‐step Chronoamperometry: Theory and Applications for Quantitative Measurements of Electrodeposited Thin Films

Published: July 2019

AbstractCyclic voltammetry (CV) has been combined with surface plasmon resonance (SPR) for probing electrochemical deposition and redox‐initiated film reorganization and conformational changes. However, the varying potential during CV scans leads to unwanted SPR background changes and complicates interpretation of SPR signals. In this work, we show that, when SPR is coupled with CV, the background correction for underpotential deposition of copper and electropolymerization of aniline is either inaccurate or difficult to perform. For accurate thickness measurements of electrodeposited films, potential‐step (PS) chronoamperometry is a method of choice to combine with SPR. The theory that interprets double‐layer charging is used to explain the advantage of PS chronoamperometry over CV in quantifying the thickness of electrodeposited thin films. The influence of the double‐layer charging on the potential‐induced SPR signal change was analyzed, and the results were used to optimize experimental parameters for PS‐SPR. Overall, PS‐SPR is easier to operate, simpler in data interpretation, and more accurate for the film thickness measurement.

Published: July 2019

AbstractThe synthetic estrogen 17α‐ethinylestradiol (EE2) is an active component of oral contraceptives. It is considered as an endocrine disrupting compound that, once incorporated into an organism, affects the hormonal balance of animals and humans. In this study we characterized the DNA‐EE2 interaction using an electrochemical biosensor and biosensing in solution phase with the double stranded DNA from salmon sperm and deoxyguanosine monophosphate (dGMP). Differential pulse voltammetry method has been applied based on voltammetric anodic responses of the deoxyguanine (dGuo) and deoxyadenine (dAdo) as well as EE2 in the medium of phosphate buffer solution pH 7.0. Binding of EE2 to the nucleobases leads to a decrease of their anodic signals. Association constant for DNA‐EE2 interaction has been estimated to be about 1.1 ⋅ 103 L mol−1 and 1.4 ⋅ 103 L mol−1 for dGuo and dAdo responses, respectively. The association is reversible as indicated by decrease of the EE2 response in pure buffer solution due to leaching of EE2 from the surface attached DNA. The DNA‐EE2 association has been confirmed also by UV‐vis spectrometric experiments.

AbstractA non‐enzyme photoelectrochemical (PEC) glucose sensor based on α‐Fe2O3 film is investigated. The α‐Fe2O3 film was fabricated via a simple spin coating method. The proposed glucose sensor exhibits good selectivity, a fast response time of <5 s, a linear range of 0.05 to 6.0 mM, sensitivity of 17.23 μA mM−1 cm−2 and a detection limit of 0.05 μM. Meanwhile, the excellent performances of the α‐Fe2O3 sensor were obtained in reproducibility and the long‐term stability under ambient condition. The linear amperometric response of the sensor covers the glucose levels in physiological and clinical for diabetic patients. Therefore, this non‐enzyme PEC sensor based on α‐Fe2O3 film has a great potential application in the development of glucose sensors.

Published: July 2019

AbstractThe possibility of selectively modifying microarray electrodes with different DNA sequences in a controlled way without the need for local positioning of solutions or local modification of array surfaces is demonstrated. Potential pulse sequences are employed to perform sequential surface modification of a 32‐gold‐electrode array with two different thiolated DNA capture sequences, surface passivation and regeneration of selected microarray electrodes, all by adjusting the potential intensities of the same potential pulse‐assisted method. We achieve reproducible and controlled DNA immobilization together with minimization of false signals originating from unspecific adsorption or undesired co‐immobilization. This methodology is not limited to DNA chips and it is potentially suitable for a wide range of applications employing Au−S chemistry. It can be employed in laboratory conditions for localizing different reactive chemistries onto predefined electrodes of an array without the need for complex and expensive apparatus and special conditions.

Published: July 2019

AbstractHere, a set of experiments to assess the feasibility of using an invasive and widespread freshwater mussel (Dreissena rostrformis bugensis) as a sentinel species for nanoplastic detection is reported. Under laboratory experimental conditions, mussels ingest and retain fluorescent polystyrene (PS) beads with carboxylic acid (COOH) termination over a size range of 200–2000 nm. The number of beads the mussels ingested is quantified using fluorescence spectroscopy and the location of the beads in the mussels is imaged using fluorescence microscopy. PS beads of similar size (1000–2000 nm) to mussels' preferred food are trafficked in the ciliated food grooves of the gills. Beads of all sizes are observed in the mussels' digestive tracts, indicating that the mussels do not efficiently reject the beads as unwanted foreign material, regardless of size. Fluorescence microscopy shows all sizes of beads are concentrated in the siphons and are retained there for longer than one month postexposure. Combined atomic force microscopy–infrared spectroscopy and photothermal infrared spectroscopy are used to locate, image, and chemically identify the beads in the mussel siphons. In sum, these experiments demonstrate the potential for using mussels, specifically their siphons, to monitor environmental accumulation of aquatic nanoplastics.
Geochronology and geochemistry of the Late Devonian–Early Carboniferous volcanic rocks in Aksu River area, western end of the East Kunlun Orogen

Published: July 2019

We present LA‐ICP‐MS zircon U–Pb dating, geochemical data for the Late Devonian–Early Carboniferous volcanic rocks in the Aksu River area, western end of the East Kunlun Orogen, with an aim to constrain the ages, petrogenesis, and tectonic setting of volcanic rocks and to comprehend the Late Devonian–Early Carboniferous tectonic evolution of the north branch of the Paleo‐Tethys Ocean. The Late Devonian–Early Carboniferous volcanic rocks are mostly composed of andesite and rhyolite. The new U–Pb ages show that the volcanic rocks formed in the Late Devonian–Early Carboniferous with ages of ca. 364–343 Ma. The volcanic rocks are classified as calc‐alkaline series. All of the volcanic rocks are characterized by enrichment in large‐ion lithophile elements (e.g., Rb, Ba, U, Sr, and K) and light rare earth elements and depletion in some high‐field‐strength elements (e.g., Nb, Ta, P, and Ti). The andesite samples have relatively high La/Nb (1.66–3.63) but low La/Ba (0.05–0.23) ratios, indicating the mantle source could be depleted mantle, and it had been metasomatized before partial melting. The rhyolite samples have low Nb/Ta and Zr/Hf ratios and Cr, Ni, and Co contents, which indicate that the material source was mainly crust derived and has experienced fractional crystallization process. Combined with our zircon U–Pb dating, geochemical data and geological field investigation, the tectonic setting of the Late Devonian–Early Carboniferous volcanic rocks is possibly related to the subduction process. Furthermore, the Paleo‐Tethys oceanic crust between the Bayan Har and East Kunlun‐Qaidam terrane northward subducted beneath the East Kunlun‐Qaidam terrane in the Late Devonian–Early Carboniferous, and the north branch of the Paleo‐Tethys Ocean between the Bayan Har and East Kunlun‐Qaidam terrane opening event should be earlier than this time (~364 Ma).
Financial incentives and physician prescription behavior: Evidence from dispensing regulations
Authors: Burkhard Daniel , Schmid Christian P. R. , Wüthrich Kaspar 
Published: July 2019

AbstractIn many health care markets, physicians can respond to changes in reimbursement schemes by changing the volume (volume response) and the composition of services provided (substitution response). We examine the relative importance of these two behavioral responses in the context of physician drug dispensing in Switzerland. We find that dispensing increases drug costs by 52% for general practitioners and 56% for specialists. This increase is mainly due to a volume increase. The substitution response is negative on average, but not significantly different from zero for large parts of the distribution. In addition, our results reveal substantial effect heterogeneity.

Published: July 2019

AbstractThe present studies (N = 159) investigated children's and adults' preferences for label and property conjunctions for cross‐classifiable toys. In Study 1, 4‐year‐olds, 5‐year‐olds, and adults participated in a labelling and property attribution task involving experimental toys that belong to two categories and control toys that belong to only one category. In Study 2, the same age groups were tested on a version of the task focusing on the control toys. In Study 3, 4‐ and 5‐year‐olds were tested on a modified version of the labelling and property attribution task involving the experimental and control toys. Finally, Study 4 tested a younger age group, 3‐year‐olds. Overall, the results indicated that by age 3 years, individuals prefer assigning experimental toys (but not controls) with joint labels that are a conjunction of two single category labels. By age 4 years, individuals prefer assigning experimental toys (but not controls) with dual properties that are a conjunction of two single properties. These results document the development of how different types of toys elicit preferences for conjunctions of labels that denote membership in two distinct categories and conjunctions of properties that combine features of these categories.HighlightsThis study examines children's preferences in labeling and attributing properties to cross-classifiable toys.Children labeled and attributed properties to toys that belonged to two categories (experimental) and one category (control).The results reveal that by 4 years, children prefer both label and property conjunctions for the experimental toys that can be cross‐classified into more than one category, but not for the control toys.
