BackgroundHematocrit and lactate have an established role in trauma as indicators of bleeding and cell death, respectively. The wide availability of CT imaging and clinical data poses the question of how these can be used in combination to predict outcomes.PurposeTo assess the utility of hematocrit or lactate trends in predicting intensive care unit (ICU) admission and hospital length of stay (LOS) in patients with torso trauma combined with clinical parameters and injury findings on CT.Materials and MethodsThis was a single-center retrospective study of adults with torso trauma in one year. Trends were defined as a unit change per hour. CT findings and clinical parameters were explanatory variables. Outcomes were ICU admission and hospital LOS. Multivariate logistic and negative binomial regression models were used to calculate the odds ratio (OR) and incident rate ratio (IRR).ResultsAmong 840 patients, 561 (72% males, age 39 ± 18) were included, and 168 patients (30%) were admitted to the ICU. Decreasing hematocrit trend [OR 2.54 (1.41–4.58), p = 0.002] and increasing lactate trend [OR 3.85 (1.35–11.01), p = 0.012] were associated with increased odds of ICU admission. LOS median was 2 (IQR: 1–5) days. Decreasing hematocrit trend [IRR 1.37 (1.13–1.66), p = 0.002] and increasing lactate trend [2.02 (1.43–2.85), p &lt; 0.001] were associated with longer hospital LOS.ConclusionHematocrit and lactate trends may be helpful in predicting ICU admission and LOS in torso trauma independent of organ injuries on CT, age, or admission clinical parameters.

Published: September 2023

In this manuscript, nanofillers of graphene oxide (GO) and cellulose nanocrystal (CNC) with different weight ratios (G/C ratios), named GC 2:1, GC 4:1, GC 8:1, GC 16:1, and GC 32:1, were successfully prepared. Characterization methods such as Raman spectroscopy, X-ray photoelectron spectrometry (XPS), and thermogravimetric analysis (TGA) were performed. Additionally, the effects of these samples on the thermal stability, mechanical properties, and gas barrier properties of polysulfone (PSF) nanocomposites were investigated. A hydrophilic interaction took place between CNC and GO; as a consequence, CNCs were modified on the surface of GO, thus repairing the structural defects of GO. With the increase in G/C ratios, the repair effect of insufficient CNCs on the defects of GO decreased. The G/C ratio had a great influence on the improvement of mechanical properties, thermal stability, and gas barrier properties of nanocomposites. Compared with PSF/GC 2:1 and PSF/GC 32:1, the differences in the growth rates of tensile strength, elongation at break, and Young’s modulus were 30.0%, 39.4%, and 15.9%, respectively; the difference in Td 3% was 7 °C; the difference in decline rate of O2 permeability was 40.0%.
Venture Capital as a New Approach to Developing Early-stage Firms in Emerging Countries;
Authors: Kato Ahmed Idi , Evelyn Germinah Chiloane -Tsoka 
Published: September 2023

This study aims to extend our knowledge of the new approaches to entrepreneurial finance that inspire the development of early-stage firms in developing countries. The role of entrepreneurship is well understood internationally owing to its substantial influence on new employment creation, and productivity, and a seedbed for the emergence of innovative young firms. The survival and prosperity of the HGFs are unswervingly linked to access to sustained financing during their early-stage growth, nonetheless, access to funding remains the topmost worry for young firms. Yet VC financing has a competitive edge over banks burrowing, which cannot easily substitute for VC in its absence. We developed a multi-regression model to measure the results using survey data of 61 VC companies dealing with over 327 investment rounds from 2015-2021. The study confirms that VC investment has a dramatically flourishing prominence in nurturing early-stage firms with potential growth. Our study makes three major contributions to advancing this debate: First, our finding is expected to benefit the policymakers and civil society in the practice of creating new VC policies or altering existing ones to attract increased foreign VC investment in active countries and beyond. The government’s increased funding to the VC companies might lead to higher survival rates for new innovative industries as observed in the developed. Moreover, we discover that this research arena is recognized by a paucity of theoretical and empirical research underpinning VC’s proficiency in nurturing high-growth firms and innovative entrepreneurship.
Discrimination of individual semiconducting and metallic single-walled carbon nanotubes by multi-wavelength photothermal microscopy
Authors: Miyazaki Jun , Maeda Honoka 
Published: September 2023

Abstract
The coexistence of semiconducting and metallic single-walled carbon nanotubes (SWCNTs) after synthesis is one of the factors preventing their practical applications. A method for quantifying the purity of a nanotube sample with high accuracy is essential because each type has different applications. In this study, we investigated the accuracy in distinguishing between semiconducting and metallic SWCNTs using multi-wavelength photothermal microscopy. Linear discrimination analysis of the multi-wavelength signals of individual nanotubes was performed to show that the two types of SWCNTs could be distinguished with more than ∼95% accuracy when the SWCNTs were embedded in a dry polymer film. In contrast, the discrimination rate decreased to about 80% when the SWCNTs were dispersed in aqueous media. The optimal wavelength combinations, number of lasers required for discrimination, and relationship between the signal-to-noise ratio and discrimination rate are also discussed.
Significant enhancement of exciton emission in monolayer WS2 treated by oleylamine ligands

Published: September 2023

Abstarct
We report a significant enhancement in photoluminescence (PL) of the monolayer WS2 treated by oleylamine ligands. After oleylamine treatment, the dominant component of the PL is converted from negative trions to excitons, indicating that the majority of excitons can recombine without forming trions. This treatment enhances exciton emission by passivating surface defects, thus reducing nonradiative recombination through surface trap states. The femtosecond transient absorption spectra further confirm that defect passivation by oleylamine ligands results in a much slower recovery of exciton resonance, reflecting suppression of early-time nonradiative recombination accompanied by a significant enhancement of exciton emission.

Published: September 2023

AbstractRepetitive thinking about negative emotions or events is strongly associated with worse mental health, whereas repetitive positive thought is generally believed to be beneficial. This observation is at odds with the idea that all forms of repetitive thinking share underlying neural mechanisms. To resolve this apparent discrepancy, the present study examined relationships between subjective affect and neural mechanisms during periods of sustained processing of positive (savoring) and negative (rumination) emotion. We also examined potential common moderators of savoring and rumination including memory specificity and sleep quality. Results indicated that individuals who experience high positive affect during savoring also are likely to experience more intense negative affect during rumination. fMRI-derived brain activity revealed common mechanisms of rumination and savoring. Memory specificity had common effects on neural correlates of rumination and savoring; sleep quality was not associated with mechanisms of savoring or rumination. These results suggest that repetitive engagement with positive and negative affect is similar both subjectively and mechanistically. Clinical interventions for rumination may benefit from capitalizing on preserved capacity for savoring.
As easy as cake or a piece of pie? Processing idiom variation and the contribution of individual cognitive differences
Authors: Carrol Gareth , Segaert Katrien 
Published: September 2023

AbstractLanguage users routinely use canonical, familiar idioms in everyday communication without difficulty. However, creativity in idiom use is more widespread than sometimes assumed, and little is known about how we process creative uses of idioms, and how individual differences in cognitive skills contribute to this. We used eye-tracking while reading and cross-modal priming to investigate the processing of idioms (e.g., play with fire) compared with creative variants (play with acid) and literal controls (play with toys), amongst a group of 47 university-level native speakers of English. We also conducted a series of tests to measure cognitive abilities (working memory capacity, inhibitory control, and processing speed). Eye-tracking results showed that in early reading behaviour, variants were read no differently to literal phrases or idioms but showed significantly longer overall reading times, with more rereading required compared with other conditions. Idiom variables (familiarity, decomposability, literal plausibility) and individual cognitive variables had limited effects throughout, although more decomposable phrases of all kinds required less overall reading time. Cross-modal priming—which has often shown a robust idiom advantage in past studies—demonstrated no difference between conditions, but decomposability again led to faster processing. Overall, results suggest that variants were treated more like literal phrases than novel metaphors, with subsequent effort required to make sense of these in the way that was consistent with the context provided.
Repetition costs in sequence chunking
Authors: Brown Rachel M. , Koch Iring 
Published: September 2023

AbstractWe examined how flexibly we plan sequences of actions when we switch between multiple action sequences. Mastering a sequential skill is assumed to involve integrating successive actions into groups known as chunks that can be efficiently planned and smoothly executed. Chunking is suggested by gains in planning efficiency for long compared to short action sequences following practice and learning associations between actions and perceptual outcomes. Less is understood about how efficiently we plan sequential chunks when we switch between multiple action sequences. Do we plan learned chunks less efficiently when we switch to a different action sequence? We examined this question by comparing the initiation and execution latencies of long versus short action sequences, performed from memory, when sequences switched or repeated across trials. Additionally, each action within the sequences generated predictable perceptual outcomes that were either spatially compatible or spatially incompatible with the action sequences. Results suggested repetition costs (instead of benefits) when performing long sequences. Repetition, as opposed to switching, prolonged initiation and increased the error rate of long compared to short sequences. We attribute these results to the flexible coordination of chunk planning and execution. Repetition may prolong advanced planning of long sequences in order to resolve conflict between multiple chunks, and switching may allow the planning of later chunks to be postponed until execution. We propose that the chunking of action sequences can both facilitate and interfere with action-switching performance.

Gaia17bpp: A Giant Star with the Deepest and Longest Known Dimming Event
Authors: Tzanidakis Anastasios , Davenport James R. A. , Bellm Eric C. , Wang Yuankun 
Published: September 2023

Abstract
We report the serendipitous discovery of Gaia17bpp/2MASS J19372316+1759029, a binary star with a deep single large-amplitude dimming event of ∼4.5 mag that lasted over 6.5 yr. Using the optical-to-IR spectral energy distribution (SED), we constrain the primary star to be a cool giant M0III star with effective temperature T
eff = 3850 K and radius R = 58 R
⊙. Based on the SED fitting, we obtained a bimodal posterior distribution of primary stellar masses with a stronger preference for a 1.5 M
⊙ mass star. Within the last 66 yr of photometric coverage, no other significant dimming events of this depth and duration were identified in the optical light curves. Using a Gaussian process, we fit a generalized Gaussian distribution to the optical and IR light curves and conclude that the dimming event exhibits moderate asymmetries from optical to IR. At the minimum of the dimming event, the Wide-field Infrared Survey Explorer color (W1–W2) differed by ∼0.2 mag relative to the primary star color outside the dimming event. The ingress and egress colors show a shallow reddening profile. We suggest that the main culprit of the dimming event is likely due to the presence of a large, optically thick disk transiting the primary giant star. By fitting a monochromatic transit model of an oblate disk transiting a star, we found good agreement with a slow-moving (0.005 km s−1) disk with a ∼1.4 au radius. We propose that Gaia17bpp belongs to a rare binary star population similar to the ϵ Aurigae system, which consists of a secondary star enshrouded by an optically thick debris disk.
Effects of Heat Conduction on Blocking off the Super-Eddington Growth of Black Holes at High Redshift
Authors: Kawanaka Norita , Kohri Kazunori 
Published: September 2023

Abstract
We investigate the effect of conductive heating of the gas surrounding a geometrically thick accretion disk on the growth of a black hole (BH) at high redshift. If a BH is accreting the surrounding gas at a super-Eddington rate, the X-ray radiation from the vicinity of the BH would be highly anisotropic due to the self-shielding of a geometrically thick accretion disk, and then the radiative feedback on the surrounding medium would be suppressed in the equatorial region, within which super-Eddington accretion can continue. However, if this region is sufficiently heated via thermal conduction from the adjacent region that is not shielded and heated by the X-ray irradiation, the surrounding gas becomes isotropically hot, and the Bondi accretion rate would be suppressed and become sub-Eddington. We evaluate the condition under which such isotropic heating is realized and derive new criteria required for super-Eddington accretion.
Effects of Barnett Magnetic Dipole–Dipole Interaction on Grain Growth and Destruction
Authors: Hoang Thiem , Truong Bao 
Published: September 2023

Abstract
Rapidly spinning magnetic grains can acquire large magnetic dipole moments due to the Barnett effect. Here we study the new effect of Barnett magnetic dipole–dipole interaction on grain–grain collisions and grain growth, assuming that grains are spun up by radiative torques. For the ideal situation in which grains have parallel Barnett dipole moments aligned with the ambient magnetic field, we find that the collision rate between grains having embedded iron inclusions can be significantly enhanced due to Barnett magnetic dipole–dipole interaction when grains rotate suprathermally by radiative torques. We discuss the implications of enhanced collision rate for grain growth and destruction in the circumstellar envelope of evolved stars, photodissociation regions, and protostellar environments. Our results first reveal the potential importance of the dust magnetic properties, magnetic fields, and the local radiation field for grain growth and destruction. Detailed numerical simulations of grain dynamics that take into account the variation of Barnett dipoles and grain alignment are required to quantify the exact role of Barnett dipole–dipole interaction in grain evolution.
Using Tianwen-1 Differential One-way Range Signals to Probe Corotating Interaction Regions: Case Studies
Authors: He Qingbao , Wang Zhichao , Liu Qinghui , Liu Kaijun , Guo Li 
Published: September 2023

Abstract
The study reports the first detection of corotating interaction regions (CIRs) in the solar wind by the differential one-way range (DOR) signals transmitted by Tianwen-1. Differential phase delay is calculated for the DOR signals. Variations of the total electron content (TEC) along the signal path between Tianwen-1 and the ground stations are then derived from changes in the differential phase delay. Large TEC variations are found for 2021 February 11, 18, and 19 even after the influence from the Earth’s ionosphere has been removed. In situ solar wind measurements and the corresponding simulation results further show that the TEC variations are caused by the CIRs that passed through the signal path on these days. The study demonstrates that CIR structures can be probed using deep-space spacecraft range signals. Such measurements can be used to constrain global solar wind forecast models.
