The impact of affective states and traits on perceptual stability during binocular rivalry
Authors: Kraus Nils , Hesselmann G.
Published: May 2023

Affective states and traits have been associated with different measures of perceptual stability during binocular rivalry. Diverging approaches to measuring perceptual stability as well as to examination of the role of affective variables have contributed to an inconclusive pattern of findings. Here, we studied the influence of affective traits, such as depressiveness and trait anxiety, and states, which were manipulated with a musical mood induction paradigm, on different measures of perceptual stability (dominance ratios and phase durations) during binocular rivalry. Fifty healthy participants reported alternations in two conditions: a biased perception condition with an unequal probability of perceiving stimuli, using an upright versus a tilted face with a neutral expression, and a control condition with equal chances of perceiving stimuli, using Gabors of different orientations. Baseline positive state affect significantly predicted longer phase durations whereas affective traits did not yield any such effect. Furthermore, in an exploratory analysis, induced negative affect attenuated stimulus related bias in predominance ratios. Overall, we found a strong correlation between both measures of perceptual stability (phase durations and dominance ratios). Our findings thus question the distinction between different measures of perceptual stability during binocular rivalry and highlight the role of affective states in its formation.
A systematic investigation of the relationship between properties of bulk foam and foam in porous media

Published: May 2023

Bulk foam analysis (static test) is simple and fast, which makes it a cost-effective method for screening and ranking hundreds of surfactants being considered for foam applications. Coreflood tests (dynamic test) can also be used, but it is quite laborious and costly. However, previous reports show that ranking based on static tests sometimes differs from ranking based on dynamic tests. To date, the reason for such a discrepancy is not well understood. Some believe that it may be due to faulty experimental design while some others believe that there is no discrepancy if the right foam performance indices are used to describe and compare the results from both methods. For the first time, this study reports a systematic series of static tests conducted on different foaming solutions (with surfactant concentration ranging from 0.025 to 5 wt%) and duplicated in dynamic tests using the same core sample for all the surfactant solutions. The dynamic test was also repeated on three different rocks of a wide permeability range (26–5000 mD) for each of the surfactant solutions. Unlike previous studies, here multiple dynamic foam indices (limiting capillary pressure, apparent viscosity, trapped foam, and trapped to mobile foam ratio) were measured and compared with the performance indices measured from the static tests (foam texture and foam half-life). Dynamic tests were in total agreement with static tests for all the foam formulations. However, it was observed that the pore size of the base filter disk used in the static foam analyzer can be a potential source of conflicting results when comparing with dynamic test. This is because a threshold pore size exists above which some foam properties (apparent viscosity and trapped foam) significantly decreased compared to the properties before that threshold. Foam limiting capillary pressure is the only foam property that does not show such a trend. It also appears that such threshold occurs above a certain surfactant concentration (0.025 wt%). Apparently, it becomes imperative that the pore size of the filter disk used in the static test and the porous medium used in dynamic tests must be on the same side of the threshold point, otherwise there may be disparity in their results. The threshold surfactant concentration should also be determined. The role of these two factors (pore size and surfactant concentration) requires further investigation.

Published: May 2023

Extracellular vesicles (EVs) are thought to mediate intercellular communication by transferring cargoes from donor to acceptor cells. The EV content-delivery process within acceptor cells is still poorly characterized and debated. CD63 and CD9, members of the tetraspanin family, are highly enriched within EV membranes and are respectively enriched within multivesicular bodies/endosomes and at the plasma membrane of the cells. CD63 and CD9 have been suspected to regulate the EV uptake and delivery process. Here we used two independent assays and different cell models (HeLa, MDA-MB-231 and HEK293T cells) to assess the putative role of CD63 and CD9 in the EV delivery process that includes uptake and cargo delivery. Our results suggest that neither CD63, nor CD9 are required for this function.
The Role of Pulsed-field Gradients in Modern NMR Pulse Sequence Design
Authors: Parella Teodor
Published: May 2023

Pulsed-field gradients (PFGs) play an important role in the development and understanding of modern NMR methods. With the ultimate goal of constructing robust pulse sequences that create high-quality NMR spectra with minimum set-up, PFGs are utilized to achieve an exclusive selection of a specific coherence transfer pathway as well as to purge all kinds of undesired magnetization. PFGs reduce the number of needed phase cycle steps to a bare minimum, allowing for accelerated NMR data acquisition in shorter spectrometer times. The potential and diversity of several PFG-based NMR elements are presented, as well as instances of their implementation in time-efficient NMR solutions. Practical aspects such as NMR data collection needs and the attainment of pure in-phase absorption lineshapes are discussed for the most useful NMR experiments.
Top Resolution in 2D NMR Spectroscopy Using Spectral Aliasing
Authors: Jeannerat D.
Published: May 2023

Obtaining the maximal possible resolution in the indirect dimension of 2D NMR spectra may require a number of free induction decays that is too large to be applicable. When the sensitivity is not a limiting factor, linearly sampling a fraction of the full set of FIDs produces Fourier-transformed spectra without compromising resolution. The price to pay for the reduction of the total acquisition time is the introduction of ambiguities with respect to the scale of the indirect dimension called spectral aliasing or folding. These ambiguities can be resolved by complementary information originating from a reference low-resolution spectrum recorded with the same pulse sequence or other spectral sources such as a 1D spectrum. The linearity of aliased spectra makes them particularly suitable for the acquisition of any series of experiments following changes in a sample composition as a function of time, spatial dimensions, temperature and other physical or chemical transformations.
Combining Fast 2D NMR Methods and Oriented Media
Authors: Lesot Philippe , Lafon Olivier
Published: May 2023

NMR in oriented samples (anisotropic solvents) offers access to informative residual order-dependent NMR interactions, including chemical shift anisotropies (RCSAs), dipolar couplings (RDCs), and quadrupolar couplings (RQCs), while preserving high spectral resolution. The analysis of these spectra often requires two-dimensional (2D) NMR experiments due to these additional anisotropic interactions. In addition, accelerated 2D NMR experiments can be essential for particular investigations, including in situ monitoring of chemical reactions or the observation of dilute isotopes, e.g. 2H and 13C, since the stability of oriented phases is limited in time and the magnetic field, B0, can drift in the absence of 2H lock. We provide here an overview of these fast 2D NMR experiments in anisotropic media. These developments have benefited from those for isotropic solutions, such as fast pulsing techniques enhancing the polarization, sparse sampling, Hadamard spectroscopy or spatial encoding. Nevertheless, fast 2D NMR in mesophases and solids present particular challenges, since these 2D spectra usually display lower signal-to-noise ratios, non-Lorentzian lineshapes, lower spectral resolution and wider spectral widths than their counterparts for isotropic solutions. We discuss here the advantages and limitations of various approaches, which have been applied for the fast 2D NMR spectra of mesophases and solids.
Fast 2D NMR to Study Microstructures
Authors: Telkki Ville-Veikko
Published: May 2023

In addition to standard solution state chemical analysis, NMR spectroscopy is also a powerful method for the studies of microstructures of solid materials. In addition to solid-state NMR, solid materials can be studied by solution state NMR techniques using either inherent or external probe fluids. This chapter is devoted to fast solution state NMR methods for studying microstructures of hard and soft matter. The first part concentrates on methods relying on chemical shift contrast. Particularly, it focuses on 129Xe NMR of xenon gas, which is broadly used in the investigations of porous materials as well as biosensor applications. It describes how spin exchange optical pumping and chemical exchange saturation transfer (CEST) techniques can be exploited to enhance the sensitivity of experiment up to seven orders of magnitude. Furthermore, it explains how CEST spectra can be measured in a single scan using spatial encoding. The second part is devoted to relaxation and diffusion contrast. It elucidates the principles of ultrafast multidimensional relaxation and diffusion experiments and describes how those experiments can be exploited in the studies of porous materials, aggregation of surfactants, intra- and extracellular metabolites in cancer cell suspensions, etc., even with low field single sided NMR devices.

Pathophysiological and Clinical Aspects of Hearing Loss Among 85-Year-Olds
Authors: Göthberg Hanna , Skoog Ingmar , Tengstrand Tomas , Magnusson Lennart , Hoff Maria , Rosenhall Ulf , Sadeghi André
Published: May 2023

Purpose:

This study aimed to identify the prevalence of conductive/mixed and sensorineural hearing loss, with an attempt to differentiate between sensory and neural components in 85-year-olds.

Method:

A comprehensive auditory test protocol, including pure-tone audiometry, speech audiometry, auditory brainstem response (ABR), and distortion product otoacoustic emission (DPOAE), was used to identify different types of hearing loss in 85-year-olds. This study comprised a subsample (
n
= 125) selected from an unscreened cohort of 85-year-olds born in 1930, within the Gothenburg H70 Birth Cohort Studies in Sweden.

Results:

Test results were reported descriptively. Sensorineural hearing loss was present in one or both ears in almost all participants (98%), and the majority had absent DPOAEs. Only approximately 6% had additional conductive hearing loss, that is, mixed hearing loss. Approximately 20% of the participants with a pure-tone average at 0.5–4 kHz < 60 dB HL had worse word recognition scores compared with predicted scores by the Speech Intelligibility Index (SII), whereas only two participants were classified with neural dysfunction with the use of ABR.

Conclusions:

Sensorineural hearing loss, likely related to outer hair cell loss, was present in the vast majority of 85-year-olds. Conductive/mixed hearing loss appears to be relatively rare in advanced age. Poor word recognition scores in relation to SII-predicted scores were relatively common (20%) in 85-year-olds, whereas auditory neuropathy was only rarely identified (1.6%) by the use of ABR latencies. To explain abnormal word recognition and to identify the neural component of hearing loss among the older-old population, future research should consider factors such as listening effort and cognition among the older-old population.
A First-Person Account of Developmental Language Disorder
Authors: Orrego Paula M. , McGregor Karla K. , Reyes Stella M.
Published: May 2023

Purpose:

The aim of this study is to share the lived experiences of an adult with developmental language disorder (DLD) and relate her experience to the evidence base and issues in clinical practice.

Method:

We co-wrote a first-person account grounded in the research literature. We organized the account into six main sections: (a) the early signs of DLD; (b) diagnosis; (c) treatment; (d) the impact of DLD on family relationships, social–emotional health, and academic performance; and (e) considerations for practicing speech-language pathologists. We close with (f) the first author's current perspective on life with DLD.

Conclusions:

The first author was diagnosed with moderate-to-severe DLD in early childhood, and she continues to exhibit subtle and occasional symptoms of DLD as an adult. At specific points in development, her family relationships were disrupted and her social, emotional, and academic functions were disabled, particularly in the school context. Supportive adults, especially her mother and her speech-language pathologist, helped lessen these impacts. DLD and its consequences also positively influenced her worldview and professional choices. The precise nature of her DLD and her experiences around the disorder will not be true of everyone with DLD. Nevertheless, the broad themes that emerge from her narrative are reflected in the evidence base and thus are likely applicable to many individuals with DLD or other neurodevelopmental conditions.
Speech Disorders in Children With Pompe Disease: Articulation, Resonance, and Voice Measures
Authors: Neel Amy T. , Crisp Kelly D. , Kishnani Priya S. , Jones Harrison N.
Published: May 2023

Purpose:

Children with Pompe disease, a rare genetic metabolic myopathy, often have speech impairments. In this study, we provide a comprehensive description of articulation, resonance, and voice in children with Pompe disease.

Method:

Fifteen children with Pompe disease (11 with infantile-onset Pompe disease [IOPD], four with late-onset Pompe disease [LOPD]) ranging from 6 to 18 years of age participated in standard speech assessments. Measures included maximum tongue pressure; nasalance; cepstral peak prominence (CPP); low/high ratio (L/H ratio); diadochokinetic (DDK) rates; percent consonants correct (PCC); and visual analog scale (VAS) ratings of articulation, resonance, voice quality, and overall speech severity. Maximum tongue pressures, nasalance, CPP, L/H ratio, DDK rates, and PCC were compared to normative data from typically developing (TD) children. Correlation analyses and multiple regression models of speech measure predictors were conducted.

Results:

Children with IOPD had greater speech impairment than those with LOPD. The IOPD group had lower maximum tongue pressures, slower articulation rates, lower PCC scores, higher nasalance, and higher L/H voice ratios than TD children. VAS ratings confirmed the presence of impaired articulatory precision, hypernasality, and dysphonia for most of the children with IOPD, with severity of impairment ratings ranging from mild to severe. The LOPD group had mildly elevated nasalance and L/H ratio values relative to TD children, and auditory-perceptual ratings suggested mild to no speech impairment.

Conclusions:

Speech disorders involving articulatory precision, resonance balance, and voice quality are common in children with Pompe disease, especially in those with IOPD. With improvements in the detection and treatment of Pompe disease, clinicians should be aware of the associated speech deficits.
A clustering approach to the definition of robust, operational and market efficient delineations for European bidding zones
Authors: Brouhard Thomas , Hennebel Martin , Petit Marc , Gisbert Cyril
Published: May 2023

In this work, we address the automated design of alternative bidding zones for Continental Europe. We base our approach on the application of clustering methods to series of locational marginal prices. These methods are adapted by using a redispatch effort index and spatial constraints in the form of geographical distances and bus adjacency. An evaluation grid that reflects the multidimensional impacts of a bidding zone revision is also provided, addressing congestion management but also price formation and the general distribution of costs and revenues between main system actors. Based on a large‐scale static grid model of the European power system, we design nine illustrative candidate zone delineations that are illustrative of current academic and institutional discussions on zone revision. A multi‐horizon assessment is also provided in relation to representative 2025, 2030 and 2040 dispatch scenarios. It is shown that while the considered alternative zone configurations can bring significant gains regarding redispatching efforts in the short run, these benefits are not robust in 2030 and 2040 scenarios. Medium to long‐term projections also show that an increase of the number of zones is likely to significantly affect price formation dynamics and lead to structural economic transfers that are to the disadvantage of consumers.
Inhibiting liquid permeation into silicone rubber by superhydrophobic coating for prolonged service life
Authors: Liu Shuming , Zhou Ying , Zuo Zhou , Liu Shuqi , Wang Qian , Chen Zhong , Liang Xidong
Published: May 2023

Liquid permeation into silicone rubber (SR) may lead to the degradation or complete failure of the composite insulators. Aiming to inhibit liquid permeation, two kinds of superhydrophobic coatings are applied to the SR surface. The liquid permeation properties of SR with different types of liquids are investigated, and the Langmuir diffusion model is applied to analyse the experimental data. The results show that the composite superhydrophobic coating can effectively inhibit liquid permeation by reducing the contact area between the surface and liquid, and the stable structure of the composite coating can maintain the performance after the liquid permeation and effusion. However, the nano‐particle coating without the polymer binder experiences severe performance degradation during the immersion test, and it cannot restrain the liquid permeation anymore after it loses the superhydrophobicity. As a validation of the effective protection, the insulation resistivity change was measured. The resistivity decreases sharply for the pristine SR after water permeation; however, the decrease is much smaller for the coated SR. The current study not only provides new insight into the liquid permeation properties of SR with different surface wettability but also suggests an effective measure to prevent liquid permeation into SR.
Precise masses and ages of ~1 million RGB and RC stars observed by LAMOST
Authors: Wang Chun , Huang Yang , Zhou Yutao , Zhang Huawei
Published: May 2023

We construct a catalogue of stellar masses and ages for 696 680 red giant branch (RGB) stars, 180 436 primary red clump (RC) stars, and 120 907 secondary RC stars selected from the LAMOSTDR8. The RGBs, primary RCs, and secondary RCs are identified with the large frequency spacing (∆ν) and period spacing (∆P) estimated from the LAMOST spectra with spectral signal-to-noise ratios (S/Ns) > 10 using a neural network method supervised with seismologic information from LAMOST-Kepler sample stars. The purity and completeness of both RGB and RC samples are better than 95% and 90%, respectively. The mass and age of RGBs and RCs are determined again with the neural network method by taking the LAMOST-Kepler giant stars as the training set. The typical uncertainties on stellar mass and age are 10% and 30%, respectively, for the RGB stellar sample. For RCs, the typical uncertainties on stellar mass and age are 9% and 24%, respectively. The RGB and RC stellar samples cover a large volume of the Milky Way (5 < R < 20 kpc and |Z| < 5 kpc), which are valuable data sets for various Galactic studies.

Published: May 2023

This research aims to better understand the high-tech industry in Indonesia so that business owners and the government can determine the best strategy for utilizing their resources. It use a descriptive and qualitative analysis approach, presenting a general profile of industry data and characteristics through national news and information. Indonesia's high-tech industry generally relies heavily on imported components or raw materials (chemicals, pharmaceuticals, computers and electronics, electrical equipment, machinery and equipment, motor vehicles, and other transportation equipment). The chemical industry significantly contributes to the economy because it can absorb large amounts of capital, create jobs, and generate added value. Because of the enormous domestic market opportunities, the pharmaceutical industry tends to build a national value chain. The electronic, optical, and electrical industries all favor indigenous innovation. To address the issue of global warming and climate change, the machinery and equipment industry must emphasize sustainable innovation by utilizing the latest technology. In contrast, the transportation industry must focus on optimizing integrated transportation services, transportation safety, and developing environmentally friendly sustainable transportation. Following the pandemic, the development of the high-tech industry began to show growth, indicating that the Indonesian economy would recover.

The concept of One Health, which has been prioritized and integrated into national strategies in developed countries as part of their sustainable development goals (SDGs), is often overlooked in developing countries, leading to unpreparedness for outbreaks. To understand global responses to One Health, we evaluated Twitter data, a microblogging social media platform with over 50 million users worldwide. Our analysis revealed that the top most tweeted words related to One Health were "onthealth", "fordnation", and "celliottability", which showed an association with Canada-based institutions and individuals, indicating Canada's leading role in implementing One Health strategies. We also found that One Health was linked to positive, negative, and neutral sentiments on Twitter. Overall, our results demonstrate that One Health triggers sentiment-polarized responses, and Twitter provides a valuable tool for gauging public sentiment and considering it in shaping One Health norms in society.

Coffee is one of the most prominent agricultural products In Indonesia, besides other commodities such as palm oil, rubber, cocoa, and tea. The International Accounting Standards Board (IASB) regulates the agriculture business in IAS 4. which was issued in December 2000 and prospectively applied worldwide on the 1st of January 2003. The standard encourages coffee plantations to be recorded at their fair value which leads to many contradictions. In 2014, IASB amended IAS 41 specifically for bearer plants because it is used only for production, and it should be treated similarly to property, plant, and equipment (PPE). The main challenge is versatility. As the growth of the coffee plantation industry in Indonesia increases, accountability has become an important issue to deal with. As there are scarce studies regarding the adoption of accounting standards for coffee plantations in Indonesia, this research is intended to give fresh insights from the business owner’s perspective in the implementation of the related agriculture accounting standards. This research employs a qualitative method with a semi-structured interview and triangulation method. Our findings show that coffee farmers already complied with the PSAK 16 and PSAK 69, even though there are still many challenges that the company faced since the coffee plants are high in versatility and uncertainty.
