Amino acid uptake by Saccharomyces cerevisiae during ethanol production
Authors: Johnston David B. , Stoklosa Ryan J. 
Published: October 2023

AbstractBackground and ObjectivesFuel ethanol produced from corn requires proper yeast nutrition. Corn without supplementation provides inadequate nitrogen at high solids levels. Inorganic nitrogen is typically added; however, organic nitrogen could also be added. To evaluate the impact of supplemental nitrogen and compare it with protease addition, we developed a solids‐free corn media to study and compare fermentations.FindingsAmino acid concentrations showed uptake occurred rapidly as fermentation started and reached near zero levels for most amino acids. After sugar utilization was complete, amino acids were released by the yeast into the media. Protease addition without supplemental nitrogen reached rates and yields equivalent to supplemented media.ConclusionsFree amino acids decrease significantly at the beginning of fermentation but, under some conditions, are released again. Protease addition increased certain amino acids and reached equivalent ethanol yields without the addition of urea. Urea allowed the yeast to produce significantly more amino acids during fermentation that were released into the media after all the available sugar was consumed.Significance and NoveltyAmino acid uptake and release in corn fermentations has not been previously reported with this detail, and the improved understanding could lead to performance benefits.

Abstract5‐Hydroxymethylfurfural (5‐HMF) synthesized through glucose conversion requires Lewis acid (L) site for isomerization and Brønsted acid (B) site for dehydration. The objective of this work is to investigate the influence of the metal type of Al‐SBA‐15‐supported phosphates of Cr, Zr, Nb, Sr, and Sn on glucose conversion to 5‐HMF in a NaCl‐H2O/n‐butanol biphasic solvent system. The structural and acid property of all supported metal phosphate samples were fully verified by several spectroscopic methods. Among those catalysts, CrPO/Al‐SBA‐15 provided the best performance with the highest glucose conversion and 5‐HMF yield, corresponding to the highest total acidity of 0.65 mmol/g and optimal L/B ratio of 1.88. For CrPO/Al‐SBA‐15, another critical parameter is the phosphate‐to‐chromium ratio. Moreover, DFT simulation of glucose conversion to 5‐HMF on the surface of the optimized chromium phosphate structure reveals three steps of fructose dehydration on the Brønsted acid site. Finally, the optimum reaction condition, reusability, and leaching test of the best catalyst were determined. CrPO/Al‐SBA‐15 is a promising catalyst for glucose conversion to high‐value‐added chemicals in future biorefinery production.

AbstractBa0.85Ca0.15Zr0.1Ti0.9O3 (BCT‐BZT) was produced via solid state reaction route at 1200. It was further fabricated into composites with silver. Phase formation was confirmed using x‐ray diffraction (XRD). Microstructures were captured using electron microscopy. Inclusion of silver creates more efficient oxygen reduction reaction (ORR). Further, these powder sample were exposed to corona poling with electric field of 4 kV/mm. These was clear improvement in electrochemical properties of poled sliver‐BCT‐BZT composites than that of unpoled samples.

AbstractThis study uses multitemporal InSAR images to assess different types of mass movements occurring in the Seydikemer (Muğla, SW Türkiye) district. A major highway connecting the Fethiye district and Antalya province and numerous small settlements of various sizes are found in the study area. In terms of summer tourism, they are Türkiye's most well‐known locations. Since the 1960s, at least according to official records, mass movements in this area have been known to negatively impact human life. Some areas have even been declared disaster zones for this reason. However, the movement's size, type, and susceptibility to landslides have all been studied in the last 10–15 years. With satellite images and field studies, distinctive lobate‐shaped movements were classified as inactive and active. During fieldwork, characteristic features such as rough topography and bending trees were easily observed and indicated extremely slow and large‐scale movement. In this study, it was found that movement less than 7–8 mm/year could be classified as ‘extremely slow’ mass movement like a ‘creep’, and moving up to 43 mm/year was evaluated as ‘very slow’ movement and ‘earth slide’ on a rigid surface. The examined moving masses with lobate geometry are activated by natural factors such as valley slope direction, stream bed flow direction, erosion of the toe of the river valleys, earthquakes, excessive precipitation, or human activities such as road opening.
Insight into light‐ and static‐electric‐field‐induced polarization on polaron‐pair dynamics in neat P3HT device: A transient‐absorption‐spectroscopy‐based study
Authors: Rana Debkumar , Materny Arnulf 
Published: October 2023

AbstractWe have investigated the polaron‐pair dynamics following the excitation of vibrationally hot exciton states in organic semiconductor‐based optoelectronic devices to better understand the photophysical properties, which can help to improve the device performance. In our earlier work, published at ‘Phys. Chem. Chem. Phys., 2019,21, 21236‐21248’, we have investigated the role of the static electric internal and external fields on the polaron‐pair dynamics in a neat poly(3‐hexylthiophene‐2,5‐diyl) based device. From this, we have concluded that the polaron‐pair dissociates into charge carriers due to the internal field present inside the device and the dissociation process accelerates when an external electric field is also applied in reverse bias. Apart from the electric‐field‐induced dissociation process, we now have also been interested in the light‐ and electric‐field‐induced polarization effect on the polaron‐pair dynamics. For this, in the present study, we have used femtosecond transient absorption spectroscopy to investigate the polaron‐pair dynamics in a neat P3HT‐based device for different angles of incidence of the light with an additional variation of the static electric field. It is well‐known that thin‐film photovoltaics can be designed for improved angle‐dependent responsivity at specific angles and the photon harvesting efficiency depends on the incident angle of light. Internal electric fields together with the electric field of the incident light both influence the charge generation efficiency of the device, which is determined by the photophysical processes happening between electronic excitation and the formation of charge. The change of reflectivity due to the variation of incident angle and the effect of the electric‐field induced polarization make an overall impact on the polaron‐pair dynamics as demonstrated by our investigations.
Changes in phenological events and long‐term seasonality in response to climate change and the ecological restoration in China's Loess Plateau

Published: October 2023

AbstractPhenology is highly responsive to environmental changes, particularly in ecologically vulnerable regions that have undergone significant anthropogenic management and rapid climate change. While previous research has mainly focused on interannual variations of specific phenological events such as the start (SOS), peak (POS), and end (EOS) of growing season, little attention has been given to abrupt shifts in long‐term phenological seasonality resulting from land management. In this study, we utilized full temporal details of Moderate Resolution Imaging Spectroradiometer‐derived normalized difference vegetation index to investigate how phenological metrics and seasonality have changed within the Loess Plateau. Our results indicated an earlier initial phase (SOS‐POS) and a prolonged POS‐EOS phenophase. Earlier spring onset was dominated by increasing water availability from the previous autumn, and earlier SOS led to an earlier POS but no significant carryover effect on EOS. In addition, spring onset of grassland was sensitive to precipitation while forest community was strongly influenced by temperature. We also reported significant changes in phenological seasonality across the plateau, and this shift in long‐term seasonality was mainly controlled by growing season precipitation. Moreover, land use/land cover change also played a role with increasing importance after the abrupt change in seasonality. In sum, our findings highlight the importance of water availability in shaping phenological patterns across this semiarid plateau and illuminate shifts in phenological seasonality that are indispensable to a comprehensive understanding of phenology dynamics.

Published: October 2023

AbstractIn this research, the effect of adding aluminum oxide nanoparticles on the flexural strength of glass/phenolic composites that were exposed to water environment was experimentally investigated. To make glass/phenolic composites, IL‐800 phenolic resin, H002 hardener, T400 bidirectional glass fibers and Al2O3 nanoparticles were used. Four‐layer composite plates were made by hand layup method. Beam‐shaped samples were extracted from the plates with the help of laser cutting method. Rectangular composite beams made of glass/phenolic and Al2O3/glass/phenolic were subjected to three‐point flexural test. The moisture absorption test was continued until the amount of water absorption reached a constant level. Bending test was performed on the samples before and after immersion in water. Based on the results, the average flexural strength of the samples after water absorption shows a decrease of about 15%. This parameter is equal to 118.96 MPa for glass/phenolic composite samples immersed in water, and by adding 0.25 wt% of Al2O3 nanoparticles into the matrix material of glass/phenolic composite samples, the flexural strength reaches 142.54 MPa, which shows an increase of 19.82% compared to samples without nanoparticles. Furthermore, the amount of flexural modulus decreases after water absorption, and the addition of nanoparticles in the base material can compensate this reduction. Scanning electron microscopy images illustrate that the addition of Al2O3 nanoparticles into the phenolic resin can enhance the strength of matrix material and improve the adhesion of glass fibers to the resin.Highlights
Addition of nano Al2O3 reduces water absorption of glass/phenolic composites.
Nano Al2O3 improves composite flexural strength after water absorption.
Addition of nano Al2O3 increases the adhesion between the layers of the specimens.

Published: October 2023

AbstractObjectiveTo describe prenatal and postnatal imaging findings of fetal adrenal hemorrhage (FAH) and its associated perinatal outcomes, including frequency of postnatal surgical intervention.MethodA systematic literature review of seven electronic databases was conducted from inception until January 2022, with 2008 articles identified reporting prenatally identified fetal adrenal masses. Studies with confirmed FAH diagnosis were included. Quality and risk assessment were evaluated.ResultsThirty‐five studies, including 102 FAH cases, were analyzed. FAH was commonly described as cystic (28/90, 31%), anechoic (25/90, 28%), or mixed echogenic (14/90, 16%) on ultrasound. Outcome data were available for 65 cases (64%) of FAH: 9% (6/65) resolved prenatally, 35% (23/65) resolved postnatally, 34% (22/65) regressed in size after birth, and 22% (14/65) persisted postnatally. Overall, 25% (16/65) of cases underwent postnatal surgical intervention. Neuroblastoma was suspected in all 16 surgical cases. Only one case (1/16, 6%) confirmed a cystic hematoma with microscopic islets of neuroblastoma in situ on pathology.ConclusionPrenatal diagnosis of FAH is challenging due to the significant heterogeneity of ultrasound findings. Final pathology did not support the need for surgical intervention. Persistent postnatal FAH warrants shared decision making for further management based on the clinical presentation.
Mind the (identification) gap: Foci in multiteam systems and their impact on innovative work behaviours
Authors: Cremers Erik Eduard , Curșeu Petru Lucian 
Published: October 2023

AbstractThe paper presents a longitudinal exploration of identification with teams and multiteam systems (MTSs) in an organizational context that started using MTSs. Data were collected in five waves during the first 2 years in which the organization started the implementation of MTSs in order to aggregate teams in value streams as organizational units. The results show that there is a clear and distinct gap between team and MTS identification. This gap is greater in larger MTSs than smaller MTSs. This gap decreases in time mostly due to a rise in MTS identification in combination with a stable team identification across time. Additionally, our research showed that MTS identification is hindered when negative relations are present in the MTS. Finally, we show that identification with the team fosters innovative team performance and the identification with MTS moderates this positive association in a compensatory manner. The findings show important implications for the management of MTSs in modern organizations.

Authors: Roshal Alexander D. 
Published: October 2023

AbstractThe review compiles information on the spectral classification of flavonoids, the changes in their electronic structure upon complex formation, and the manifestation of these changes in the absorption and emission spectra. Part of the review is devoted to the regioselectivity of the complex formation process, including types of complexation sites, the structure of chelates and ′open′ complexes, and the correlation between the structure of complexes and their spectral properties. The interplay between complex formation and other processes occurring in flavonoids during electronic excitation is also considered, such as intramolecular inter‐fragment charge transfer (ICT) and intramolecular proton transfer (ESIPT). The review also contains systematic data on the study of regioselectivity and spectral properties of flavone complexes, obtained by the author and their colleagues over the past decades.

They assess immigrants’ acts of writing their stories as a part of the decolonization process in migration studies. In this part, the authors also engage in a process of reflexivity and share their statement of positionality, which shapes the rest of the chapter. They express where they stand individually in relation to creative scholars whose reflexive writings have inspired them and the StOries Project participants with whom they have collaborated. The second part surveys the differential impacts of the recent pandemic on various groups, with a specific focus on migrants and racialized groups. The third section elaborates on autoethnography as a method of inquiry. The fourth section highlights key themes in individual contributions. Considering thematically related entries together, the editors make references to relevant extant research. The final section presents the pandemic stories of the StOries Project in the order discussed by the editors.

An insertability constraint for shape optimization
Authors: Garner Eric , Wu Jun , Zadpoor Amir A. 
Published: October 2023

AbstractPatient-specific implants offer a host of benefits over their generic counterparts. Nonetheless, the design and optimization of these components present several technical challenges, among them being the need to ensure their insertability into the host bone tissue. This presents a significant challenge due to the tight-fitting nature of the bone-implant interface. This paper presents a novel insertability metric designed to efficiently assess whether a rigid body can be inserted into a tight-fitting cavity, without interference. In contrast to existing solutions, the metric is fully differentiable and can be incorporated as a design constraint into shape optimization routines. By exploiting the tight-fitting condition, the problem of planning an interference-free insertion path is reformulated as the search for a single interference-free movement, starting from the inserted configuration. We prove that if there exists any outward movement for which no interference is indicated, then the body can be fully extracted from or, equivalently, inserted into the cavity. This formulation is extremely efficient and highly robust with respect to the complexity of the geometry. We demonstrate the effectiveness and efficiency of our method by applying it to the optimization of two-dimensional (2D) and three-dimensional (3D) designs for insertability, subject to various design requirements. We then incorporate the proposed metric into the optimization of an acetabular cup used in total hip replacement (THR) surgery where geometric and structural requirements are considered.
Quantification of thaumatin-like proteins in white wine using MALDI-TOF mass spectrometry
Authors: Rašková Michaela , Perutka Zdeněk , Marchetti-Deschmann Martina , Šebela Marek 
Published: October 2023

AbstractThe main soluble proteins in bottled wine are pathogenesis-related proteins. Their concentration is influenced by the harvesting technique used, the time of the juice exposition to grape skins and possible microbial infection of grapes. The most typical are namely chitinases and thaumatin-like proteins (TLPs), which accumulate in grapes on ripening. They show a low molecular weight of 20–35 kDa and are resistant to proteolysis as well as the acidic pH of wine. Chitinases are considered the primary cause of heat-induced haze formation because of their irreversible denaturation and aggregation. This process can additionally be affected by the non-protein wine components. We focused on the development of a fast quantification method for wine TLPs using matrix-assisted laser desorption/ionization mass spectrometry. White wine samples were analyzed directly, after dialysis or they were subjected to protein concentrating procedures before the measurements. MS-based quantification was achieved by comparing the peak areas of an internal standard (cytochrome c, thaumatin or myoglobin) and TLPs in the acquired mass spectra. The content of TLPs in commercial wines was determined at milligrams per liter. Chitinases could not be quantified in this way because of a low concentration in the analyzed bentonite-fined wines resulting in missing spectral signals. Anyway, this procedure becomes an alternative to common quantification methods based on liquid chromatography.

Abstract
Purpose
To provide an overview of outcome and complications of selective dorsal rhizotomy (SDR) and intrathecal baclofen pump implantation (ITB) for spasticity treatment in children with hereditary spastic paraplegia (HSP).

Methods
Retrospective study including children with HSP and SDR or ITB. Gross motor function measure (GMFM-66) scores and level of spasticity were assessed.

Results
Ten patients were included (most had mutations in ATL1 (n = 4) or SPAST (n = 3) genes). Four walked without and two with walking aids, four were non-walking children. Six patients underwent SDR, three patients ITB, and one both. Mean age at surgery was 8.9 ± 4.5 years with a mean follow-up of 3.4 ± 2.2 years. Five of the SDR patients were walking. Postoperatively spasticity in the legs was reduced in all patients. The change in GMFM-66 score was + 8.0 (0–19.7 min–max). The three ITB patients treated (SPAST (n = 2) and PNPLA6 (n = 1) gene mutation) were children with a progressive disease course. No complications of surgery occurred.

Conclusions
SDR is a feasible treatment option in carefully selected children with HSP, especially in walking patients. The majority of patients benefit with respect to gross motor function, complication risk is low. ITB was used in children with severe and progressive disease.
