Mysticism’s Musical Modalities: Philosophies of Audition in Medieval Persian Sufism
Authors: Strohm Reinhard 
Published: January 2020

For many Persian poets, Sufis in particular, the ethereal modes through which music communicates with its listeners embodied the somatic ‘taste’ (ẕauq) of the suprasomatic divine realities. Through a dialectic of revelation and concealment—or in the Qur’anic terms often employed by the Sufis, ẓāhir and bạ̄tin, exoteric and esoteric—proper musical experience (samāᶜ) becomes both a means of accessing the transcendent harmonies of the cosmos and conduit to the very transcendence of music itself. Proper hearing is not delimited by the audible range of the material ear, for this external sense (ḥiss-i ẓāhir) must yield to an internal sense (ḥiss-i bāṭin), signified by the gūsh-i jān and gūsh-i dil, the ‘ear of the soul’ and ‘ear of the heart’. These auricular metaphors express a deeply Pythagorean but specifically Persianate philosophy of audition, one not (only) grounded in the rationality of mathematical ratios, but (also) modelled upon Pythagoras’ cosmic auditory powers, bestowed through ritual purity.

Published: January 2020

We report some large ornithopod vertebrae from two upper Hauterivian-lower Barremian (Lower Cretaceous) localities in El Castellar (Maestrazgo Basin, Teruel,Spain).These fossils have been studied systematically as well as morphometrically using a multivariate analysis in order to analyse the diversity of the sample. In fact, principal component analysis has been demonstrated as a useful tool for establishing affinities in isolated iguanodontian vertebrae, at least when size effect is not removed from the analysed dataset. As result of this study, twolarge indeterminate styracosternans are distinguished in the sample: a large one with platycoelus anterior caudal vertebrae related to the genera Magnamanusand Iguanodon, and a middle-sized one with longer-than-high dorsal vertebrae and amphicoelus anterior caudal vertebrae related to Morelladon. Such diversity of large ornithopods observed in the upper Hauterivian-lower Barremian of the Maestrazgo Basin is similar to that previously observed in Western Cameros Basin and it demonstrates the presence of at least two different forms of styracosternan in this stratigraphic range of the Iberian Peninsula.

Background: Herpes simplex virus type 2 (HSV-2) causes genital herpes, a chronic viral infection that is sexually transmitted and often results in genital ulcer disease (GUD) worldwide.
Aim: The aim of this study was to determine the prevalence of herpes simplex virus type 2 (HSV-2) IgG and IgM antibodies and the associated risk factors among undergraduate female students of Babcock University.
Methods: After ethical approval was obtained, serum samples of 150 consenting female participants (16-35 years) were collected randomly and screened using NADALR HSV-2 IgG/IgM Rapid Antibody Test Cassette (Bulgarian Company for Biotechnology, Sofia, Bulgaria). The demographic and clinical information of the participants were also collected using a structured questionnaire. The results were statistically analyzed using the SPSS version 18.0.
Results: The outcome of the study shows that out of the 150 participants screened, 5 (3.3%) were positive for HSV-2 IgG antibody, 4 (2.7%) were positive for HSV-2 IgM; while 2 (1.3%) were positive for both HSV-2 IgG and IgM antibodies. There were no significant differences (P>0.05) in the seropositivity for HSV-2 IgG and IgM antibodies among the study participants on the basis of age distribution. With regards to clinical indication for genital herpes in relation to seropositivity of HSV-2 IgG and IgM antibodies among the study participants, none of the 7 (4.6%) who indicated vaginal itching was seropositive for either HSV-2 IgG or HSV-2 IgM or both. On the other hand, genital lesions were recorded in 0.7% HSV-2 IgG seropositive, 1.3% HSV-2 IgM seropositive and 0.7% HSV-2 both IgG and IgM seropositive. Genital ulcer was recorded among two participants who were either seropositive for HSV-2 IgG (0.7%) or HSV-2 IgM (0.7%). Only one (0.7%) participant indicated inguinal lymphadenopathy, however, the person was HSV-2 IgG/IgM seronegative. Identifiable risk factor significantly (P<0.05) associated with HSV-2 infection include: history of sexually transmitted infections, HIV positive status, and change of sex partners recently.
Conclusion: The outcome of this study shows that HSV-2 infection exists among undergraduate female students of Babcock University, Nigeria and therefore appropriate public health measures must be taken to halt the cycle of infection within the University community. Early detection of genital herpes and prompt treatment will help prevent subsequent complications such as genital ulcer disease among young female adults.

Abstract2D homojunctions have stimulated extensive attention because of their perfect thermal and lattice matches, as well as their tunable band structures in 2D morphology, which provide fascinating opportunities for novel electronics and optoelectronics. Recently, 2D nonlayered materials have attracted the attention of researchers owing to their superior functional applications and diverse portfolio of the 2D family. Therefore, 2D nonlayered homojunctions would open the door to a rich spectrum of exotic 2D materials. However, they are not investigated due to their extremely difficult synthesis methods. Herein, nonlayered CdSe flakes homojunctions are obtained via self‐limited growth with InCl3 as a passivation agent. Interestingly, two pieces of vertical wurtzite‐zinc blende (WZ‐ZB) homojunctions epitaxially integrate into WZ/ZB lateral junctions. These homojunctions show a divergent second‐harmonic generation intensity, strongly correlated to the multiple twinned ZB phase, as identified by aberration‐corrected scanning transmission electron microscopy and theoretical calculations. Impressively, the photodetector based on this WZ/ZB CdSe homojunction shows excellent performances, integrating a high photoswitching ratio (3.4 × 105) and photoresponsivity (3.7 × 103 A W−1), suggesting promising potential for applications in electronics and optoelectronics.

Published: January 2020

AbstractPure ionic conductors as solid‐state electrolytes are of high interest in electrochemical energy storage and conversion devices. They systematically involve only one ion as the charge carrier. The association of two mobile ionic species, one positively and the other negatively charged, in a specific network should strongly influence the total ion conduction. Nb5+‐ (4d0) and Ti4+‐based (3d0) derived‐perovskite frameworks containing Na+ and O2− as mobile species are investigated as mixed ion conductors by electrochemical impedance spectroscopy. The design of Na+ blocking layers via sandwiched pellet sintered by spark plasma sintering at high temperatures leads to quantified transport number of both ionic charge carriers tNa+ and tO2−. In the 350–700 °C temperature range, ionic conductivity can be tuned from major Na+ contribution (tNa+ = 88%) for NaNbO3 to pure O2− transport in NaNb0.9Ti0.1O2.95 phase. Such a Ti‐substitution is accompanied with a ≈100‐fold increase in the oxygen conductivity, approaching the best values for pure oxygen conductors in this temperature range. Besides the demonstration of tunable mixed ion conduction with quantifiable cationic and anionic contributions in a single solid‐state structure, a strategy is established from structural analysis to develop other architectures with improved mixed ionic conductivity.

AbstractA new small‐molecule nonfullerene acceptor based on the benzo[1,2‐b:4,5‐b′]dithiophene (BDT) fused central core with asymmetrical alkoxy and thienyl side chains, namely TOBDT, is designed and synthesized. The alkoxy unit helps narrow the bandgap, and thienyl side chain helps enhance the intermolecular interaction. As a result, TOBDT is suitable to match the deep‐lying highest occupied molecular orbital (HOMO) of polymer donor PM6. Then, a strong crystalline acceptor IDIC is introduced as the third component to fabricate as‐cast nonfullerene ternary devices to achieve absorption and morphology control. Addition of IDIC not only mixes well with TOBDT but modulates the morphology of the blend film, which helps to balance the charge transport properties and reduce the photovoltage loss of ternary devices. All these contribute to synergetic improvement of Jsc, Voc, and fill factor parameters, leading to a power conversion efficiency of 14.0% for the as‐cast fullerene‐free ternary device.

AbstractImproving the quality of perovskite poly‐crystalline film is essential for the performance of associated solar cells approaching their theoretical limit efficiency. Pinholes, unwanted defects, and nonperovskite phase can be easily generated during film formation, hampering device performance and stability. Here, a simple method is introduced to prepare perovskite film with excellent optoelectronic property by using acetic acid (Ac) as an antisolvent to control perovskite crystallization. Results from a variety of characterizations suggest that the small amount of Ac not only reduces the perovskite film roughness and residual PbI2 but also generates a passivation effect from the electron‐rich carbonyl group (CO) in Ac. The best devices produce a PCE of 22.0% for Cs0.05FA0.80MA0.15Pb(I0.85Br0.15)3 and 23.0% for Cs0.05FA0.90MA0.05Pb(I0.95Br0.05)3 on 0.159 cm2 with negligible hysteresis. This further improves device stability producing a cell that maintained 96% of its initial efficiency after 2400 h storage in ambient environment (with controlled relative humidity (RH) <30%) without any encapsulation.
Protein Nanosphere Anchors for Stabilizing Hydroxylated Polymer Chains in Organic Memory Transistors with Outstanding Retention Characteristics

Published: January 2020

AbstractIt is demonstrated that a heme protein (cytochrome c [Cyt c]) nanosphere plays a strong anchoring role in binding hydroxyl groups of poly(vinyl alcohol) (PVA) leading to outstanding high‐temperature (100 °C) retention characteristics of transistor‐type organic memory devices (TOMDs). The PVA:Cyt c layers are spin‐coated on indium tin oxide gate electrodes from aqueous solutions with various Cyt c contents up to 50 wt%, followed by the formation of poly(3‐hexylthiophene) (P3HT) channel layers and nickel/aluminum top source/drain electrodes in TOMDs. Results show that adding 20 wt% Cyt c improves the drain current of devices in the presence of good hysteresis characteristics, which are maintained even after exposure to high‐temperature conditions (100 °C). The excellent conservation of hysteresis characteristics is attributed to the formation of Cyt c nanospheres that act as an anchoring point to retard the relaxation of PVA chains via specific interactions (hydrogen bonding etc.) between amino groups in the Cyt c nanosphere surfaces and hydroxyl groups in the PVA chains. The optimized PVA:Cyt c layers (20 wt% Cyt c, thermal treatment at 100 °C) deliver excellent retention characteristics to TOMDs, whereas no memory function is measured in the case of the pristine PVA layers at 100 °C.

AbstractReduced lignin alfalfa (Medicago sativa L.) has the potential to improve alfalfa forage quality, yet forage morphology, biomass allocation, and stem and leaf forage nutritive value remains undetermined. The objectives of this study were to characterize changes in morphological development and forage nutritive value within stem and leaf fractions for reduced lignin alfalfa. Reduced lignin (‘54HVX41’) and reference (‘DKA43‐22RR’) alfalfa cultivars were sampled weekly from the mid‐vegetative stage through full flower during the seeding (2015) and first production (2016) year at two locations in Minnesota. Samples were staged to determine maturity, divided into stem and leaf fractions, weighed, and analyzed for forage nutritive value. Alfalfa cultivars were similar in stem and leaf yield, leaf to stem ratio (L/S), stem crude protein (CP), stem neutral detergent fiber (NDF), leaf CP, leaf NDF, leaf acid detergent lignin (ADL), and leaf NDF digestibility (NDFD). On average, reduced lignin alfalfa showed a 14% decrease in stem ADL and a 12% increase in stem NDFD compared to reference alfalfa. For both cultivars, increases in forage maturity increased stem and leaf yields and decreased L/S. Forage maturity also affected stem and leaf forage nutritive values; as maturity increased, NDF and ADL increased while CP and NDFD decreased. These results indicate that changes in forage nutritive value for reduced lignin alfalfa are largely a result of changes in ADL and NDFD within the stem fraction, and confirm that alfalfa forage nutritive value is negatively affected by forage maturity, particularly within the stem portion of the plant.

AbstractInterseeding alfalfa (Medicago sativa L.) can improve forage quality of grasslands by adding a high‐protein species, but this runs the risk of accelerating soil water depletion. The objective was to evaluate effects of cultivar and row spacing of alfalfa on soil water balance and plant water potentials (Ψ) of two upright‐type cultivars, NuMex Bill Melton and WL 440HQ, and a prostrate‐type Falcata‐Rhizoma blend, interseeded into native grasses in October 2015 near Lubbock, Texas. Alfalfa was interseeded at 36‐cm (narrow) and 71‐cm (wide) row spacings. Soil volumetric water content (VWC) and midday Ψstem and Ψleaf were measured weekly in 2017 and 2018 growing seasons. Soil VWC was not affected by alfalfa cultivars (P > .05), whereas alfalfa row spacings differed (P < .05). Narrow spacing caused lower (P < .05) VWC than wide spacing relative to the grass‐only control in both the upper 40‐ and 40‐ to 100‐cm layers of the soil. Wide‐row spacing had similar VWC to control in 2017 for both soil layers (P > .05). Soil water depletion increased with alfalfa crown density (r = .60, P < .05) in association with enhanced evapotranspiration and denser root mass below 30‐cm soil depth. Grass and alfalfa Ψstem and Ψleaf were depressed in narrow rows relative to wide rows and control, indicating that presence of alfalfa intensified competition with the grass for soil water. The wide‐row treatment seldom had adverse effects on grass water stress. Wide‐row spacing achieved a favorable compromise between enhanced water use and improved stand productivity.
Arabica coffee–macadamia intercropping: Yield and profitability with mechanized coffee harvesting

Published: January 2020

AbstractArabica coffee (Coffea arabica L.)–macadamia (Macadamia integrifolia Maiden & Betche) intercropping presents benefits at the initial phase; however, coffee yields gradually decline because of shading, and mechanized coffee harvesting may be impeded by the growth of macadamia trees. An experiment was conducted under irrigated conditions in southeastern Brazil to evaluate whether coffee–macadamia intercropping and the use of pruning to allow mechanized coffee harvesting offers agronomic and economic advantages over continuously cropped coffee monoculture (monocropped coffee). In addition, we aimed to evaluate which macadamia cultivar (Hawaiian cultivars; HAES 344, HAES 660, and HAES 816; Brazilian cultivars: IAC 9–20, IAC 4–12B, and IAC 4–20) is most suitable for long‐term intercropping with mechanized coffee harvesting. Hawaiian macadamia cultivars have a narrower canopy, requiring less pruning of the lateral branches to allow the traffic of the mechanical coffee harvester. The macadamia cultivar IAC 4–12B had the highest kernel yield and IAC 4–20 had the lowest yield. Because intercropped treatments have 33.3% fewer coffee plants and their production per plant was reduced by shading, the coffee yield in these treatments was on average 38% lower than that in monocropped coffee. However, due to the sale of the macadamia kernel, coffee–macadamia intercropping was economically superior to coffee monoculture. Depending on the macadamia cultivar, the economic benefit of intercropping was from 9% (IAC 4–20) to 206% (HAES 816 and IAC 4–12B) higher than that achieved with monocrop coffee cultivation.

AbstractCropland contaminated by crude oil typically requires remediation before it can meet pre‐contaminated productivity potentials. Remediation strategies focus on removing the contaminant, but they also often alter soil properties, which affects the capacity of the land to sustain agricultural production. This research describes crop production following the remediation of crude oil contaminated soil in North Dakota, USA using two different strategies, a modified land‐farming technique and ex situ thermal desorption. Wheat (Triticum aestivum L.) and field pea (Pisum sativum L.) were grown in soils treated by both of those techniques, as well as mixtures of each treated soil with native topsoil. Across three growing seasons of comparisons to native topsoil, crop production was 61 ± 20% lower in the modified land‐farm soils and 52 ± 25% lower in thermal desorption‐treated soils; these yield declines were likely associated with reduced soil organic carbon levels. Notably, the soil mixtures had higher soil organic carbon levels and matched the native topsoil in both yield and protein content, suggesting that soil mixing may be a promising tool in cropland soil reclamation. Overall, these findings reinforce that crop production on reclaimed land is linked with soil properties, so long‐term reclamation success requires a holistic approach to soil management.

ObjectiveTo investigate β‐amyloid and tau depositions using Pittsburgh compound B (PiB) positron emission tomography (PET) and AV1451 tau PET imaging in aging multiple sclerosis (MS) patients.MethodsPatients with MS (n = 16) and controls (n = 80) matched for age, sex, andAPOEε4 status from the population‐based Mayo Clinic Study of Aging who underwent PiB PET imaging were studied. Of these individuals, 12 patients with MS and 60 matching controls also underwent AV1451 tau PET. Cortical PiB and AV1451 standard uptake value ratios (SUVrs) from the entire cortex and previously determined Alzheimer disease (AD) signature regions in the same population were calculated for group comparisons and testing for associations with age.ResultsAD signature PiB SUVr (odds ratio [OR] [95% confidence interval (CI)] = 0.52 [0.27–0.98],p= 0.044), total cortical PiB SUVr (OR [95% CI] = 0.52 [0.28–0.99],p= 0.048), and the frequency of abnormal PiB SUVrs (OR [95% CI] = 0.10 [0.01–0.90],p= 0.040) were lower in MS than controls. Although AD‐signature and total cortical AV1451 SUVrs were not different between the groups, the frequency of abnormal AV1451 SUVrs was higher (OR [95% CI] = 10.65 [1.10–103.35],p= 0.041) in MS than controls. The association of AD signature PiB SUVr with age was steeper in the controls compared to patients with MS (estimate [95% CI] = −0.14 [−0.023 to −0.006],p= 0.002). Similarly, the association of total cortical PiB SUVr with age was steeper in the controls compared to patients with MS (estimate [95% CI] = −0.13 [−0.021 to −0.005],p= 0.002). There was no difference in the association of AV1451 SUVr findings with age between the MS patients and controls.InterpretationAlthough both β‐amyloid and tau are biomarkers of cognitive aging and AD, cortical β‐amyloid deposition was lower in MS than age‐matched controls, suggesting that some aspect of MS pathobiology retards the accumulation of β‐amyloid but not the accumulation of tau.ANN NEUROL 2020;87:556–567

AbstractThe effect of donor (D)–acceptor (A) alignment on the materials electronic structure was probed for the first time using novel purely organic porous crystalline materials with covalently bound two‐ and three‐dimensional acceptors. The first studies towards estimation of charge transfer rates as a function of acceptor stacking are in line with the experimentally observed drastic, eight‐fold conductivity enhancement. The first evaluation of redox behavior of buckyball‐ or tetracyanoquinodimethane‐integrated crystalline was conducted. In parallel with tailoring the D‐A alignment responsible for “static” changes in materials properties, an external stimulus was applied for “dynamic” control of the electronic profiles. Overall, the presented D–A strategic design, with stimuli‐controlled electronic behavior, redox activity, and modularity could be used as a blueprint for the development of electroactive and conductive multidimensional and multifunctional crystalline porous materials.
