Sound for Thought: Listening as Metabolism
Authors: Butera Michael Vincenzo 
Published: January 2019

The metaphor of metabolism, in its permeating and incorporative senses, can extend fruitfully beyond digestion. Here, I consider it as analogous to the phenomenological process of audition. Neither static nor disaffected in a state of abstract rationality, but necessarily implicated in the objects and contexts of listening, the auditor ingests, accepts, disseminates, and expulses sound. Through this, we might see the beginnings of a phenomenological vocabulary which is based in incorporative perceptual subjectivity (not universal aesthetics) and the inimitable character of audition (thus not primarily visualistic). Beyond the construction of an organic auditory phenomenology, the analogy of metabolism and audition suggests a reciprocal correspondence between the listening subject and the world within which sounds are manifested. Furthermore, these metaphors speak to a specific history of philosophical discourse concerning issues of temporal subjectivity, oral othering, and affective perception.

I identify meaning as a property of utterance, the situated instance of language use, and locate its presence in the soundscape as a point of reference for all humans that constitute a particular acoustic community. My starting point is the premise that our experience of aural space and the soundscape are so profoundly connected to our experience of what it is to be human that there is a direct relationship, established over millennia, between the environments in which communication takes place and the ways in which we communicate. Further to this, I suggest that sound is the binding agent in a dialogic relationship between consciousness, environment and context. I argue that this binding operates through a process in which differing degrees of awareness and recognition of soundscape features, structures and inter-relations facilitate a shift between basic hearing functions and more informed modes of listening. This leads, in turn, to expression through mimicry, performativity and utterance. In other words, the dialogic characteristic of the relationship is located in the reciprocity between hearing, speaking and environmental phenomena. The central hypothesis of this paper states that, without sound binding us into this dialogic relationship with environment and context, we would not have been able to develop inter-human sounds in order to function as social beings. I argue that this relationship underpins the formation of linguistic tools that both help structure, and provide access to the perceptual and conceptual knowledge of the world that we store in memory. This combined knowledge structure informs both our external engagements and sense of self. Both my initial premise and hypothesis are supported by theoretical and practical research, including participant observation and feedback from a series of sound installations designed to progress the inquiry.

Published: January 2019

AbstractNonmetallic plasmonic heterostructure TiO2‐mesocrystals/WO3−x‐nanowires (TiO2‐MCs/WO3−x‐NWs) are constructed by coupling mesoporous crystal TiO2 and plasmonic WO3−x through a solvothermal procedure. The continuous photoelectron injection from TiO2 stabilizes the free carrier density and leads to strong surface plasmon resonance (SPR) of WO3−x, resulting in strong light absorption in the visible and near‐infrared region. Photocatalytic hydrogen generation of TiO2‐MCs/WO3−x‐NWs is attributed to plasmonic hot electrons excited on WO3−x‐NWs under visible light irradiation. However, utilization of injected photoelectrons on WO3−x‐NWs has low efficiency for hydrogen generation and a co‐catalyst (Pt) is necessary. TiO2‐MCs/WO3−x‐NWs are used as co‐catalyst free plasmonic photocatalysts for CO2 reduction, which exhibit much higher activity (16.3 µmol g−1 h−1) and selectivity (83%) than TiO2‐MCs (3.5 µmol g−1 h−1, 42%) and WO3−x‐NWs (8.0 µmol g−1 h−1, 64%) for methane generation under UV–vis light irradiation. A photoluminescence study demonstrates the photoelectron injection from TiO2 to WO3−x, and the nonmetallic SPR of WO3−x plays a great role in the highly selective methane generation during CO2 photoreduction.

Published: January 2019

AbstractThere is currently no cure for gene mutation‐caused autosomal dominant polycystic kidney disease (ADPKD). Over half of patients with ADPKD eventually develop kidney failure, requiring dialysis or kidney transplantation. Current treatment modalities for ADPKD focus on reducing morbidity and mortality from renal and extrarenal complications of the disease. MicroRNA has been shown to be useful in treating ADPKD. This study combines anti‐miRNA plasmids and iron oxide/alginate nanoparticles for conjugation with antikidney antibodies. These nanocomposites can specifically target renal tubular cells, providing a potential treatment for ADPKD. Magnetic resonance imaging and in vivo imaging system results show effective targeting of renal cells. Anti‐miRNA plasmids released from the nanocomposites inhibit cell proliferation and cyst formation in the PKD cellular and animal models. The results suggest the novel combination of the anti‐miRNA plasmids and nanomaterials provides potential clinical implications for ADPKD treatment.

AbstractStretchable light‐emitting diodes (LEDs) and electroluminescent capacitors have been reported to potentially bring new opportunities to wearable electronics; however, these devices lack in efficiency and/or stretchability. Here, a stretchable organometal‐halide‐perovskite quantum‐dot LED with both high efficiency and mechanical compliancy is demonstrated. The hybrid device employs an ultrathin (<3 µm) LED structure conformed on a surface‐wrinkled elastomer substrate. Its luminescent efficiency is up to 9.2 cd A−1, which is 70% higher than a control diode fabricated on the rigid indium tin oxide/glass substrate. Mechanical deformations up to 50% tensile strain do not induce significant loss of the electroluminescent property. The device can survive 1000 stretch–release cycles of 20% tensile strain with small fluctuations in electroluminescent performance.

Published: January 2019

AbstractBiomass is the most abundant renewable resource on earth and developing high‐performance nonprecious selective hydrogenation (SH) catalysts will enable the use of biomass to replace rapidly diminishing fossil resources. This work utilizes ZIF‐67‐derived nitrogen‐doped carbon nanotubes to confine Co nanoparticles (NPs) with Co–Nx active sites as a high‐performance SH catalyst. The confined Co NPs with Co–Nx exhibit excellent catalytic activity, selectivity, and stability toward a wide range of biomass‐derived compounds. Such active sites can selectively hydrogenate aldehyde, ketone, carboxyl, and nitro groups of biomass‐derived compounds into value‐added fine chemicals with 100% selectivity. The reported approach could be adopted to create other forms of catalytically active sites from other nonprecious metals.

AbstractA straightforward, rapid method to create colloidally stable and brightly luminescent core/shell CdSe‐based nanoplatelets (NPLs) with fluorescence quantum yields (QYs) up to 50% is demonstrated. A layer‐by‐layer deposition technique is used which is based on a two‐phase mixture—consisting of a nonpolar phase, which includes the NPLs, and a saturated ionic polar phase—to separate the reagents and hinder the nucleation of the shell material. The deposition of the first sulfur layer leads to a significant redshift (by more than 100 nm) of the optical absorption and emission of the NPLs. Hence, by varying either the sulfur precursor content or the reaction time, one can precisely and continuously tune the absorption and emission maxima from 520 to 630 nm. This evolution of the absorption onset during the shell growth is explained quantitatively using density‐functional theory and atomistic statistical simulations. The emission can be further enhanced by exposure of the NPL solution to ambient sunlight. Finally, it is demonstrated that the core/shell NPLs can be transferred from the organic solution to aqueous media with no reduction of their QY, which opens the door to a broad range of practical applications.

AbstractIt is discovered that “bridging” traditional persistent room‐temperature phosphorescence (pRTP) dibenzofuran moieties by intermolecular hydrogen bonding can induce interesting photophysical properties. The light‐emitting material 4‐(4‐((4‐methoxyphenyl)sulfonyl)phenyl)dibenzo[b,d]furan (SOBF‐OMe) is synthesized and excitingly shows novel dual‐emissive afterglow material properties in which orange pRTP (at ≈580 nm, 627 ms) from the dibenzofuran moiety and another blue ultralong intermolecular charge transfer emission (≈476 nm, 204 ms, with TADF characteristics) can be detected. Due to the different decay lifetimes, the ratio of the two afterglow emission bands continuously changes. Accordingly, the emission colors are unusually tuned gradually from cold‐white to orange during the afterglow decay process. The blue afterglow emission, which relates to intermolecular interactions, is sensitive to mechanical stimuli and the afterglow emission properties of SOBF‐OMe (single‐emissive or dual‐emissive) can easily be manipulated by grinding/fuming. This single‐component material is a rare example of a light‐emitting compound showing dual‐emissive and real‐time changing afterglow properties in which a rational bridging strategy via weak intermolecular hydrogen bonding is utilized.

Published: January 2019

AbstractMagnetoresistance (MR) effects not only have great applications in magnetic sensors, hard disk drive (HDD) read heads, and magnetic random access memory (MRAM), but also are expected to develop next‐generation computing systems. Recently, the MR ratio is found to be significantly increased in diode‐enhanced MR (DEMR) devices by coupling the Hall effect or anomalous Hall effect of magnetic materials and the nonlinear transport property of diodes. However, these devices cannot satisfy the requirement of high sensitivity at low magnetic field and small working current simultaneously. Here, large MR ratio (−6850% at 6 T) and high magnetic‐field sensitivity (−875% at 0.04 T) with small working current (<0.5 mA) are achieved at room temperature by combining ZnCoO film and diode. A theoretical model is established quantitatively, which can well explain the experimental observations and be used for evaluating the device performance. Based on this combined device, a logic unit with magnetoelectric symmetry is constructed by introducing a magnet as control bit. Through manipulating the control bit and tuning the working current, 15 Boolean logic functions can be carried out. This work will be beneficial for extending the functionality of spintronic logic‐in‐memory devices and provide a promising solution for realizing emerging computing systems.
Is a strong dollar bad for US agriculture?
Authors: French Jordan 
Published: January 2019

AbstractUsing a panel of financial statements from 42,557 US farms over an 8‐year period for a total of 256,648 annual financial statements, this study examined the relationship between the US dollar and farm financial performance. Additionally, commodity prices, imports, exports, production inputs, and macroeconomic variables were also examined in relation to the financial performance of the agricultural community. Linear, logistic, and panel regressions, as well as Granger causality tests and impulse response simulations were all used to increase the robustness of the findings. It was found that farm financials were more likely to improve with an improving economy, strengthening dollar, and/or rising commodity prices. Also, as production increased, farm financials would be more likely to have weaker financial ratios. It was found that the US and world economies impacted the dollar, the dollar impacted prices, and prices impacted both production and exports. The findings are pertinent to not just farmers, forecasters, and commodity traders, but also financial institutions (i.e., Farm Credit Service Organizations) that now must build their own forecasting models under the new Financial Accounting Standards Board's current expected credit loss requirements.

Abstractpara‐TsOH‐promoted cascade reaction of easily prepared ortho‐propynol phenyl azides for the synthesis of 4‐methoxy quinolines has been developed. This reaction proceeded in a new way to generate 4‐methoxy quinolines through a concerted nucleophilic mechanism of propargyl methyl ether. It is worth noting that propargyl methyl ether can be successfully transformed into 4‐methoxy quinolines only when substrates contain a strong electron‐donating group (OR).
The value of surveying the kidneys during pelvic ultrasound examinations
Authors: Brennan Orlaith , Oh Sheila , Necas Martin 
Published: January 2019

AbstractIntroductionPelvic ultrasounds are commonly performed for various clinical indications in female patients presenting to the hospital. A survey of the kidneys is routinely included as part of the examination, but there is limited justification for their inclusion in the assessment of every female presenting for a pelvic ultrasound.MethodWe examined the utility of surveying the kidney ultrasound during pelvic ultrasonography by reviewing the records of 1009 pelvic ultrasound examinations in 1000 women.ResultsIn total, 46 incidental findings were identified, but 91% of these were clinically inconsequential. Only four patients had incidental findings of high clinical priority requiring specialist treatment. Of these, two patients were symptomatic and had urinary tract obstruction due to stones. The other two patients harboured asymptomatic renal cell carcinomas. The overall incidence of renal incidental findings of high clinical priority in asymptomatic patients was two in 1009 examinations (1999 kidneys).ConclusionIndiscriminate uncritical screening of the kidneys in women presenting for pelvic ultrasound is not evidence‐based and represents a low‐yield examination with extremely low rate of incidental findings of clinical significance.
Fabrication and cell morphology of a microcellular poly(ether imide)–carbon nanotube composite foam with a three‐dimensional shape
Authors: Feng Dong , Liu Pengju , Li Li 
Published: January 2019

ABSTRACTThe preparation of microcellular poly(ether imide) (PEI) based foams with three‐dimensional geometry remains a great challenge worldwide. In this study, we fabricated microcellular PEI–carbon nanotube (CNT) bead foams with a batch rapid depressurization method in a self‐designed mold with supercritical carbon dioxide (scCO2) as a blowing agent. The effects of the saturation time, foaming temperature, foaming pressure, and depressurization rate on the microcellular structures of the PEI foam were analyzed by the Taguchi approach to determine the optimum foaming conditions, and the influence of the CNT content on the cell structure was analyzed. The results show that the depressurization rate and foaming temperature were the key factors influencing the cell size and cell density (Nf); that is, the high depressurization rate and low foaming temperature favored a small cell size and highNf. The foaming temperature also influenced the foaming ratio (ϕ), and a high ϕ was obtained at a high foaming temperature. Under optimal foaming conditions, PEI with 2.0 wt % CNTs presented the best cell structure;Nf,cell size, and ϕ were 6.14 × 1010cell/cm3, 2.43 μm, and 2.08, respectively. The mechanical properties of the final parts were related more to the foaming time and CNT concentration, and the maximum tensile and compression strength were reached at 3 h foaming time and 2.0 wt % CNT, that is, at 2.75 and 15.1 MPa (10% strain), respectively. © 2019 Wiley Periodicals, Inc.

Synthesis and controlled release of curcumin‐β‐cyclodextrin inclusion complex from nanocomposite poly(N‐isopropylacrylamide/sodium alginate) hydrogels
Authors: Kasapoglu‐Calik Meltem , Ozdemir Murat 
Published: January 2019

ABSTRACTInclusion complex of curcumin with β‐cyclodextrin (Cur‐β‐CD) was prepared using coprecipitation method. Stoichiometric ratio between curcumin and β‐cyclodextrin was found to be 1:2 with an association constant of3.80 × 108M−2using Benesi–Hildebrand method. Inclusion complex formation was confirmed by FTIR and DSC analyses. Water solubility of curcumin increased from 0.00122 to 0.721 mg mL−1with the inclusion complex formation. Release of the inclusion complex from the nanocomposite and conventional poly(N‐isopropylacrylamide/sodium alginate hydrogels crosslinked by nanoclay andN,N′‐methylenebis(acrylamide) (BIS), respectively, were investigated in simulated gastrointestinal conditions. Swelling ratio and cumulative release were dependent on the hydrogel composition and pH. At pH = 1.2, hydrogels showed the lowest release ratio, but at pH = 6.8 highest swelling ratios were attained. The swelling ratio and cumulative release decreased with increasing the nanoclay content in nanocomposite hydrogels. On the contrary, as the ratio of BIS in the conventional hydrogels increased, the swelling ratio and cumulative release increased. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2019,136, 47554.

AbstractFreshwater ecosystems are under a constant risk of being irreversibly damaged by human pressures that threaten their biodiversity, the sustainability of ecosystem services (ESs), and human well‐being. Despite the implementation of various environmental regulations, the challenges of safeguarding freshwater assets have so far not been tackled successfully.A promising way forward to stop the loss of freshwater biodiversity and to sustain freshwater‐based ESs is by implementing ecosystem‐based management (EBM), an environmental planning and adaptive management approach that jointly considers social and ecological needs. Responsible for considerable recent success in sustainably managing and conserving marine ecosystems, EBM has not yet been championed for fresh waters.A major reason for the delayed uptake of EBM in fresh waters is likely to be its complexity, requiring planners to be familiar with the latest developments in a range of different research areas. EBM would therefore benefit from becoming more tangible to receive attention on the ground.To facilitate uptake, eight core research areas for EBM and their innovations are introduced, and the way in which they feed into the workflow that guides the EBM planning stage is explained.The workflow links biodiversity distributions with ES supply‐and‐demand modelling and SMART (specific, measurable, attainable, relevant, and timely) target planning, including scenario‐ and cross‐realm perspectives, the prioritization of management alternatives, spatial prioritization of biodiversity conservation and ES areas, and the quantification of uncertainties. Given the extensive resources, time, and technical capacity required to implement the full workflow, a light and an ultralight version of the workflow are also provided.Applied in concert, the eight well‐known research areas allow for better planning and operationalizing, and eventually for implementing EBM in freshwater ecosystems. EBM has great potential to increase public acceptance by introducing the consideration of human needs and aspirations into typically biodiversity‐driven conservation and management approaches. This will ultimately improve the integrity of freshwater ecosystems.
