Gold OA Pricewatch #2 – BMC journal APCs increase
Authors: Mounce Ross 
Published: October 2023

Just a quick note that BMC journal APC’s have increased from what they were in 2012. Luckily I had the 2012 data saved on my computer so I can compare prices directly. I’ve put the data for 97 journals (not all of them) here on figshare.
<strong>
The mean price increase is just over 5%
</strong>
. Although to give it a fair statistical treatment – the median price increase is just 3.3% (to 1 d.p.). There is a lot of variance.

O número de registros de pesticidas de acordo com o MAPA (2021) aumentou 85% de 2000 a 2021. No primeiro semestre de 2020 o Ministério da Agricultura já havia publicado o registro de 150 agrotóxicos para uso no Brasil. Destes, 118 agrotóxicos foram liberados só entre março a maio, com 84 deles destinados agricultura e 34 para uso na indústria. A Agência Nacional de Vigilância Sanitária (ANVISA), aponta que parte dessas novas mercadorias devem ser reavaliadas, pelas possíveis ligações a casos de câncer. Concomitante a isso, as empresas que concentram a produção de veneno, já haviam solicitado a liberação de mais 216 produtos.

Perception and Practice of Nonmedical Use of Opioids among Young People in Ibadan, Nigeria
Authors: Badewo Olurogba John , Titiloye Musibau Ayoade 
Published: October 2023

Background: The opioid crisis is a growing public health concern globally. This study investigated the opioid use among young people in Nigeria.
Method: A cross-sectional design was employed using self-administered questionnaire adapted from the WHO student drug-use survey tool. A four-stage sampling technique was used to select the respondents. The data were analyzed with SPSS version 20.
Results: The respondents’ mean age was 21.1±2.7 years. There were more male (57.3%) respondents. About 56.5% of the respondents had a poor perception of opioid use. The lifetime prevalence of codeine syrups, dihydrocodeine, Co-codamol, and tramadol use was 14.4%, 13.5%, 13.0%, and 11.4%, respectively, while the past-year was 13.6%, 10.0%, 12.7%, and 10.0%, respectively, and the past-month 12.5%, 13.0%, 12.2%, and 9.4%, respectively. Most of the respondents involved in opioid use were introduced to it by friends/peers (codeine [42.5%]; tramadol [56.1%]). The age of onset of opioid use was 15–19 years (codeine) and > 20 years (tramadol). Perception of opioid abuse was significantly associated with nonmedical use of opioids.
Conclusion: The respondents’ perception of opioid use was significant with lifetime, past-year, and past-month nonmedical use of opioids; hence, public enlightenment is needed as a strategy to curb the menace of the opioid crisis among young people.
Video ocular counter roll: A bedside test of otolith‐ocular function
Authors: Yang Yuchen , Tian Jing , Otero‐Millan Jorge , Kheradmand Amir 
Published: October 2023

AbstractHere we review the clinical value of a video‐oculography test for clinical evaluation of vestibular otolith function. This test is known as the video ocular counter roll (vOCR) and is based on measurement of torsional vestibulo‐ocular reflex with a lateral head tilt. The vOCR test consists of a simple maneuver during which the head and torso are tilted en bloc by the examiner. The pattern of vOCR deficit among patients highlights its clinical value in identifying the stage of vestibular loss and recovery. The quick application of vOCR allows examination of otolith‐ocular function and assessment of vestibular recovery at the bedside.

AbstractObjectiveThe present study aims to determine whether angiographic differences increase the risk of ischemic pattern among adult patients with moyamoya disease (MMD).MethodsFrom January 2020 to December 2021, we retrospectively enrolled 123 ischemic or asymptomatic adult patients diagnosed as MMD. Angiographic changes including Suzuki stage, moyamoya vessels, anterior choroidal artery (AChoA) dilatation, lenticulostriate artery (LSA) dilatation, posterior communicating artery (PcomA) dilatation, and posterior cerebral artery (PCA) involvement were evaluated for all patients.ResultsAmong the 123 participants, 35 ischemic patients and 88 asymptomatic patients were analyzed. There was no significant difference of Suzuki stage, AChoA dilatation, LSA dilatation, and PcomA dilatation between ischemic group and asymptomatic group. The grading of moyamoya vessels differed significantly but was not a factor associated with ischemic pattern after adjusting multiple related confounders. However, the frequency of PCA steno‐occlusive changes in ischemic patients was statistically higher than that in asymptomatic patients (54.3% vs 34.1%, p = 0.039). Furthermore, PCA involvement was a risk factor associated with ischemic form and remained statistically significant after the multivariate adjustment (p = 0.033, 95% CI 1.092–8.310).InterpretationPCA involvement is closely related to the presentation of ischemic stroke but other angiographic features had no association with ischemic pattern in adult MMD.
Highly Anisotropic Mechanical Response of the Van der Waals Magnet CrPS4

Published: October 2023

AbstractSemiconducting van der Waals magnets exhibit a rich physical phenomenology with different collective excitations, as magnons or excitons, that can be coupled, thereby offering new opportunities for optoelectronic, spintronic, and magnonic devices. In contrast with the well‐studied van der Waals magnets CrI3 or Fe3GeTe2, CrPS4 is a layered metamagnet with a high optical and magnon transport anisotropy. Here, the structural anisotropy of CrPS4 above and below the magnetic phase transition is investigated by fabricating nanomechanical resonators. A large anisotropy is observed in the resonance frequency of resonators oriented along the crystalline a‐ and b‐axis, indicative of a lattice expansion along the b‐axis, boosted at the magnetic phase transition, and a rather small continuous contraction along the a‐axis. This behavior in the mechanical response differs from that previously reported in van der Waals magnets, as FePS3 or CoPS3, and can be understood from the quasi‐1D nature of CrPS4. The results pinpoint CrPS4 as a promising material in the field of low‐dimensional magnetism and show the potential of mechanical resonators for unraveling the in‐plane structural anisotropy coupled to the magnetic ordering that, in a broader context, can be extended to studying structural modifications in other 2D materials and van der Waals heterostructures.

AbstractThe omnipresence of charge density waves (CDWs) across almost all cuprate families underpins a common organizing principle. However, a longstanding debate of whether its spatial symmetry is stripe or checkerboard remains unresolved. While CDWs in lanthanum‐ and yttrium‐based cuprates possess a stripe symmetry, distinguishing these two scenarios is challenging for the short‐range CDW in bismuth‐based cuprates. Here, high‐resolution resonant inelastic x‐ray scattering is employed to uncover the spatial symmetry of the CDW in Bi2Sr2 − xLaxCuO6 + δ. Across a wide range of doping and temperature, anisotropic CDW peaks with elliptical shapes are found in reciprocal space. Based on Fourier transform analysis of real‐space models, the results are interpreted as evidence of unidirectional charge stripes, hosted by mutually 90°‐rotated anisotropic domains. This work paves the way for a unified symmetry and microscopic description of CDW order in cuprates.
Construction of Functionalized ortho‐Naphthoquinone Methides via Site‐Selective Ring Opening of 1‐Siloxy‐1,4‐epoxy‐1,4‐dihydronaphthalenes

Published: October 2023

Abstract1‐Siloxy‐4‐(benzyloxy)methyl‐1,4‐epoxy‐1,4‐dihydronaphthalenes, generated from benzynes and furans, underwent automatic site‐selective ring opening because of the synergetic effect of the steric strain of the 1,4‐epoxy moiety and the electron‐donating ability of the siloxy group on the acetal structure to afford the precursors of ortho‐naphthoquinone methides (o‐NQMs). Subsequent Lewis acid‐facilitated o‐NQM formation and annulation with olefins afforded multi‐fused heterocycles. Notably, the consecutive hexacyclic skeleton of rubioncolin B was constructed via solvent‐dependent regioselective annulation of naphthofuran derivatives.
Toward De Novo Catalyst Discovery: Fast Identification of New Catalyst Candidates for Alcohol‐Mediated Morita–Baylis–Hillman Reactions**
Authors: Rasmussen Maria H. , Seumer Julius , Jensen Jan H. 
Published: October 2023

AbstractRecently we have demonstrated how a genetic algorithm (GA) starting from random tertiary amines can be used to discover a new and efficient catalyst for the alcohol‐mediated Morita–Baylis–Hillman (MBH) reaction. In particular, the discovered catalyst was shown experimentally to be eight times more active than DABCO, commonly used to catalyze the MBH reaction. This represents a breakthrough in using generative models for catalyst optimization. However, the GA procedure, and hence discovery, relied on two important pieces of information; 1) the knowledge that tertiary amines catalyze the reaction and 2) the mechanism and reaction profile for the catalyzed reaction, in particular the transition state structure of the rate‐determining step. Thus, truly de novo catalyst discovery must include these steps. Here we present such a method for discovering catalyst candidates for a specific reaction while simultaneously proposing a mechanism for the catalyzed reaction. We show that tertiary amines and phosphines are potential catalysts for the MBH reaction by screening 11 molecular templates representing common functional groups. The method relies on an automated reaction discovery workflow using meta‐dynamics calculations. Combining this method for catalyst candidate discovery with our GA‐based catalyst optimization method results in an algorithm for truly de novo catalyst discovery.
Clustering Six Electrons within “Dawson‐Like” Polyoxometalate: An Open Route toward Its Post‐functionalization

Published: October 2023

AbstractSuper‐reduction of polyoxometalates (POMs) in solution is of fundamental interest for designing innovative energy storage systems. In this article, we show that the “Dawson‐like” POM can undergo a disproportionation process during its massive electron uptake, leading to species containing three metal‐metal bonds as evidenced by X‐ray diffraction, multi‐nuclear magnetic resonance spectroscopy (1H and 183W NMR), extended X‐ray absorption fine structure (EXAFS), UV/Vis, and voltammetry techniques. This result indicates that electron storing within metal‐metal bonds is not a unique property of Keggin‐type POM as postulated since the 70s. Besides, we demonstrate that the presence of an electron‐rich triad in the “Dawson‐like” POM allows its post‐functionalization with additional tungstate ions, generating a chiral molecule that is also the largest WIV‐containing POMs known to date.
Crystalline 2π Aromatic Azadiboriridinylium: A BN Analogue of Cyclopropenylium Cation
Authors: Zhu Lizhao , Kinjo Rei 
Published: October 2023

AbstractN‐Substitution of a thermally unstable diboratriazole 1 with a trimethylsilyl group affords a remarkably stable diboratriazole derivative 2. Ring contraction of 2 with an N‐heterocyclic carbene accompanied by the release of N2 as well as 1,4‐hydrogen shift affords a carbene‐stabilized azadiboriridine 3. Abstraction of the H−B3mem hydride in 3 with methyl trifluoromethanesulfonate leads to the isolation of a hitherto unknown azadiboriridinylium 4, the first BN analogue of cyclopropenylium cation. X‐ray diffraction analysis and computational studies confirmed the delocalization of π electrons over the B2N three‐membered ring, indicating the 2π aromatic feature. Compound 4 undergoes ring expansion reactions with azobenzene and pyridazine to furnish triazadiborolidinylium species 5 and 6, the latter of which possesses a cationic B2N3 ring with a pronounced 6π aromatic property. Moreover, the reaction of 4 with a diazo compound produces a cationic B2N3C pentafulvene derivative 7.

Published: October 2023

AbstractBoron (B) alloying transforms the magnetoelectric antiferromagnet Cr2O3 into a multifunctional single‐phase material which enables electric field driven π/2 rotation of the Néel vector. Nonvolatile, voltage‐controlled Néel vector rotation is a much‐desired material property in the context of antiferromagnetic spintronics enabling ultralow power, ultrafast, nonvolatile memory, and logic device applications. Néel vector rotation is detected with the help of heavy metal (Pt) Hall‐bars in proximity of pulsed laser deposited B:Cr2O3 films. To facilitate operation of B:Cr2O3‐based devices in CMOS (complementary metal‐oxide semiconductor) environments, the Néel temperature, TN, of the functional film must be tunable to values significantly above room temperature. Cold neutron depth profiling and X‐ray photoemission spectroscopy depth profiling reveal thermally activated B‐accumulation at the B:Cr2O3/ vacuum interface in thin films deposited on Al2O3 substrates. The B‐enrichment is attributed to surface segregation. Magnetotransport data confirm B‐accumulation at the interface within a layer of ≈50 nm thick where the device properties reside. Here TN enhances from 334 K prior to annealing, to 477 K after annealing for several hours. Scaling analysis determines TN as a function of the annealing temperature. Stability of post‐annealing device properties is evident from reproducible Néel vector rotation at 370 K performed over the course of weeks.
In Situ Monitoring of the Al(110)‐[EMImCl] : AlCl3 Interface by Reflection Anisotropy Spectroscopy
Authors: Guidat Margot , Rahide Fatemehsadat , Löw Mario , Kim Jongmin , Ehrenberg Helmut , Dsoke Sonia , May Matthias M. 
Published: October 2023

AbstractRecently, Al‐batteries (AlBs) have become promising candidates for post‐lithium batteries, with [EMImCl] : AlCl3 (1 : 1.5) as the most commonly used electrolyte. However, progress in the development of AlBs is currently hindered by the lack of understanding of its solid‐electrolyte interface. Monitoring the structure of this interface under operational conditions by complementary spectroscopy could help to identify and overcome bottlenecks of the system. Reflection anisotropy spectroscopy (RAS), an optical in situ technique, provides access to physical and chemical properties of electrochemical interfaces on an atomistic level. Herein, we report the first example of RAS as an in situ characterization technique for non‐aqueous battery systems, investigating an Al(110)‐based model system. During chemical pre‐treatment in [EMImCl] : AlCl3, the Al(110) surface passivation film is modified. The oxide film is partially etched while an inhomogeneous passivation layer forms, increasing the surface roughness. Upon electrochemical cycling, applied potential‐dependent oscillations of the anisotropy are observed and demonstrate the applicability of RAS to monitor phenomena such as plating/stripping and surface passivation in real‐time.
Perceptual anchoring effects: Evidence of response bias and a change in estimates sensitivity
Authors: Garcia‐Marques Teresa , Fernandes Alexandre 
Published: October 2023

AbstractIntroductionPeople's estimates of perceptual quantities are commonly biased by the contextual presence of other quantities (like numbers). In this study, we address assimilation anchoring effects (approximation of real quantities to contextual quantities) that occur for visually displayed proportions, defining a new methodological setting for the effect.MethodSimilar to classic approaches, we asked participants across several trials whether the display contained a feature in a proportion higher or lower than “a randomly selected value” (relative judgments), and then estimated the feature proportions (absolute judgments). Across all trials, we presented seven anchors ranging from .20 to .80, each with a visually displayed representation of the same seven proportions (49 judgments in total). This allowed for a psychophysical approach to individual estimates and signal detection indexes, providing new insights into how the anchoring effect is generated in this setting.ResultsOur findings suggest that anchoring effects occur both as a bias (changes in response criteria) and as a change in the ability to discriminate stimuli (affecting sensitivity indexes). Moreover, anchors modulate the level of stimuli features for which estimates were more uncertain. Finally, our results indicate that anchor effects occur immediately in the first phase of the two‐phase paradigm, leading to the availability of values for supporting absolute estimates.ConclusionBy using a psychophysical approach to the anchoring effects, for the first time, we could clarify that this effect is the result of both bias and changes in the ability to discriminate quantity.

Published: October 2023

AbstractOverseeding of bermudagrass (Cynodon dactylon L.) with perennial ryegrass (Lolium perenne L.) is often performed to provide green cover of dormant warm‐season turfgrass in the winter. Fraise mowing is a cultural practice that can be used to disrupt the soil surface and hasten establishment of overseeded perennial ryegrass. Research was conducted to determine the most effective timing of overseeding for perennial ryegrass establishment in Northeast Mississippi, and to compare fraise mowing with other common cultural practices performed to enhance overseeding establishment. Treatments included fraise mowing at two depths (0.3 or 0.6 inches), scalping to a height of 1 inch, or vertical mowing to a depth of 1 inch at three timings (mid‐September, mid‐October, and end‐October) prior to seeding perennial ryegrass at 435 lb pure live seed acre−1. Plots were evaluated weekly for turfgrass quality, visual perennial ryegrass cover, and total green cover with digital image analysis. Fraise mowing to a depth of 0.6 inches and scalping resulted in quicker perennial ryegrass establishment. Fraise mowing to a depth of 0.3 inches resulted in quicker perennial ryegrass establishment than both the untreated control and vertically mowed treatments. End‐October fraise mowing resulted in the slowest establishment, as growing conditions were not favorable for perennial ryegrass growth. Although the mid‐September and mid‐October treatments provided the most rapid perennial ryegrass establishment, almost all seeding timings were visually similar by March 15th of the following year. Though fraise mowing temporarily causes an undesirable playing surface, more rapid perennial ryegrass establishment is afforded by restricting bermudagrass competition.
