Stock returns and earnings persistence following equity financing and earnings announcement: Considering managerial characteristics
Authors: Chen Jing‐Chi , Liao Li‐Kai (Connie) 
Published: June 2024

AbstractThis study examines whether future stock returns and earnings persistence decline when a firm has issued equity within 1 month of its earnings announcement (post‐EA equity financing), considering managerial ability and overconfidence. The results show that when overconfident managers engage in post‐EA equity financing, buy‐and‐hold returns significantly decrease in the subsequent month and earnings persistence is low within the subsequent year. However, firms with overconfident, high‐ability managers do not experience lower returns following post‐EA equity financing and have larger earnings variability within the subsequent 3 years. The decline in returns in the month during post‐EA equity financing is more pronounced for firms with high financial constraints or low financial flexibility with overconfident managers. Overall, our results highlight the managerial traits of firms that engage in equity issuance after information release.

AbstractConsidering the potential threats posed by oily wastewater to the ecosystem, it is urgently in demand to develop efficient, eco‐friendly, and intelligent oil/water separation materials to enhance the safety of the water environment. Herein, an intelligent hydrogel‐coated wood (PPT/PPy@DW) membrane with self‐healing, self‐cleaning, and oil pollution detection performances is fabricated for the controllable separation of oil‐in‐water (O/W) emulsions and water‐in‐oil (W/O) emulsions. The PPT/PPy@DW is prepared by loading polypyrrole (PPy) particles on the delignified wood (DW) membranes, further modifying the hydrogel layer as an oil‐repellent barrier. The layered porous structure and selective wettability endow PPT/PPy@DW with great separation performance for various O/W emulsions (≥98.69% for separation efficiency and ≈1000 L m−2 h−1 bar−1 for permeance). Notably, the oil pollution degree of PPT/PPy@DW can be monitored in real‐time based on the changed voltage generated during O/W emulsion separation, and the oil‐polluted PPT/PPy@DW can be self‐cleaned by soaking in water to recover its separation performance. The high affinity of PPT/PPy@DW for water makes it effective in trapping water from the mixed surfactant‐stabilized W/O emulsions. The prepared eco‐friendly and low‐cost multifunctional hydrogel wood membrane shows promising potential in on‐demand oil/water separation and provides new ideas for the functional improvement of new biomass oil/water separation membrane materials.

AbstractBlade‐coating stands out as an alternative for fabricating scalable perovskite solar cells. However, it demands special control of the precursor composition regarding nucleation and crystallization and currently exhibits lower performance than the spin‐coating process. It is mainly the resulting film morphology and excess lead iodide (PbI2) distribution that influences the optoelectronic properties. Here, the effectiveness of introducing N‐Methyl‐2‐pyrrolidone (NMP) to regulate the structure of the perovskite layer and the redistribution of PbI2 is found. The introduction of NMP leads to the accumulation of excess PbI2, mainly on the top surface, reducing residual PbI2 at the perovskite buried interface. This not only facilitates the passivation of perovskite grain boundaries but also eliminates the potential degradation of the PbI2 triggered by light illumination in the perovskite buried interface. The optimized NMP‐modified inverted perovskite solar cell achieves a champion efficiency of 24.5%, among the highest reported blade‐coated perovskite solar cells. Furthermore, 13.68 cm2 blading perovskite solar modules are fabricated and demonstrate an efficiency of up to 20.4%. These findings underscore that with proper modulation of precursor composition, blade‐coating can be a feasible and superior alternative for manufacturing high‐quality perovskite films, paving the way for their large‐scale applications in photovoltaic technology.
Zum Beultragverhalten von Kreiszylinderschalen aus hochfesten Stählen unter Axial‐ und Umfangsdruck

Published: June 2024

AbstractSchalentragwerke in Stahlbauweise wurden in der Vergangenheit weitestgehend aus normalfesten Baustählen oder nichtrostenden austenitischen Stählen mit niedrigen Festigkeiten gefertigt. Vermehrt kommen allerdings hochfeste nichtrostende Duplex‐Stähle nach DIN EN 10088‐4, ‐5 zum Einsatz, z. B. in Biogasfermentern. Der Einsatz hochfester Stähle reduziert nicht nur den Materialeinsatz und die Fertigungskosten, sondern auch den Montageaufwand und erhöht somit die Wettbewerbsfähigkeit von Tank‐ und Silobehältern in Stahlbauweise. Eine Voraussetzung ist jedoch, dass das Stabilitätsversagen in Form von Schalenbeulen ausgeschlossen werden kann. Die europäischen Bemessungsnormen für Schalentragwerke DIN EN 1993‐1‐6, ‐4‐1, ‐4‐2 sind auf normalfeste Baustähle ausgelegt und berücksichtigen abschließende Nachweisformate weder für ring‐ und axialversteifte Kreiszylinderschalen noch für hochfeste Baustähle und nichtrostende Stähle mit einem bereits unterhalb der 0,2%‐Dehngrenze auftretenden nichtlinearen Materialverhalten. Im Rahmen des IGF‐Forschungsvorhabens Nr. 21719N „Tragverhalten axial‐ und ringversteifter Tank‐ und Silobehälter aus hochfesten (Duplex‐)Stählen und kaltzähen Druckbehälterstählen“ werden daher systematische Untersuchungen an (un‐)versteiften Kreiszylinderschalen am Institut für Metall‐ und Leichtbau (IML) der Universität Duisburg‐Essen (UDE) und an der Versuchsanstalt für Stahl, Holz und Steine (VAKA) am Karlsruher Institut für Technologie (KIT) durchgeführt. Die ersten gewonnenen Erkenntnisse dieses Forschungsvorhabens werden hier vorgestellt.

AbstractEnzymatically modified starch offers a potential biodegradable coagulating agent. However, most of the research in this area mainly focuses on corn starch, leaving cassava starch underexplored. This study investigates the coagulation efficacy of cassava starch modified by α‐amylase (AA), glucoamylase (GA), and their combination. The results show that the dual‐enzyme modified starch demonstrates excellent coagulation performance, compared to the single‐enzyme counterparts as well as the unmodified native starch. It reduces the coagulation time of the whole blood by 3.47 min and exhibits a 90.1% increase in liquid absorption rate. The average micrometer‐level pore size and specific surface area (SBET) also increase by 1.72 µm and 9.37 m2 g−1, respectively. Furthermore, the coagulation time of enzyme‐modified starch displays a negative correlation with liquid absorption rate, average micrometer‐level pore size, and SBET. This suggests that larger pores efficiently guided blood into starch micropores, while higher SBET enhances the coagulation factor aggregation. Additionally, DSC results indicate a synergistic effect of AA and GA on cassava starch. This investigation presents a promising effect of dual‐enzyme on cassava starch for potential wound hemostasis applications.

AbstractBackgroundEarly Barrett cancer can be curatively treated by endoscopic resection. The choice of the resection technique, however—endoscopic mucosal resection (EMR) or submucosal dissection (ESD)—largely depends on the assumed infiltration depth as judged by the endoscopist. However, the accuracy of endoscopic diagnosis of the degree of cancer infiltration is not known.MethodsThree to four high‐quality images (both in overview and close‐up) from 202 of early Barrett esophagus cancer cases (82% men, mean age 66.9 years) were selected from our endoscopy database (73.3% stage T1a and 26.7% in stage T1b). Images were shown to 9 Barrett esophagus experts, with patients' clinical data (age, sex, Barrett esophagus length) and biopsy results. The experts were asked to predict infiltration depth (T1b vs. T1a), and to suggest the appropriate endoscopic resection technique (EMR or ESD, or surgery). Interobserver variability (kappa values) was also determined for these parameters.ResultsOverall positive (PPV) and negative predictive values (NPV) to diagnose T1b versus T1a infiltration were 40.7% (95% CI: 36.7, 44.8) and 79.8% (95% CI: 77.5, 81.9), respectively; kappa value was 0.41. Paris classification (kappa 0.51) and suggested treatment also varied between experts. In a post hoc analysis, only the correlation between lesions classified as invisible or flat according to the Paris classification (IIB; 25% of all cases) and the suggested resection technique was better: In this subgroup, EMR was recommended in >80% of cases, with a high complete (basal R0) resection rate (mean of 88.1%).ConclusionsPrecise endoscopic distinction between mucosal and submucosal involvement of Barrett esophagus cancer by experts as a basis for choosing the resection technique has limited predictive values and high interobserver variability. It seems that mainly invisible/flat lesions may result in good resection outcomes when treated by EMR, but this stratification strategy has to be assessed in further studies.
The MAPK homolog, Smk1, promotes assembly of the glucan layer of the spore wall in S. cerevisiae

Published: June 2024

AbstractSmk1 is a MAPK homolog in the yeast Saccharomyces cerevisiae that controls the postmeiotic program of spore wall assembly. During this program, haploid cells are surrounded by a layer of mannan and then a layer of glucan. These inner layers of the spore wall resemble the vegetative cell wall. Next, the outer layers consisting of chitin/chitosan and then dityrosine are assembled. The outer layers are spore‐specific and provide protection against environmental stressors. Smk1 is required for the proper assembly of spore walls. However, the protective properties of the outer layers have limited our understanding of how Smk1 controls this morphogenetic program. Mutants lacking the chitin deacetylases, Cda1 and Cda2, form spores that lack the outer layers of the spore wall. In this study, cda1,2∆ cells were used to demonstrate that Smk1 promotes deposition of the glucan layer of the spore wall through the partially redundant glucan synthases Gsc2 and Fks3. Although Gsc2 is localized to sites of spore wall assembly in the wild type, it is mislocalized in the mother cell cytoplasm in the smk1∆ mutant. These findings suggest that Smk1 controls assembly of the spore wall by regulating the localization of Gsc2 during sporogenesis.

Abstract
We study the LHC phenomenology of an Axion Like Particle (ALP) that couples only derivatively with the top quark at tree level. We inspect the radiatively induced couplings with the SM fermions and (gauge) bosons and the associated production and decay mechanisms of the ALP. We focus on the most challenging mass window that remains open for a top-philic ALP, i.e., the range between tens and hundreds of GeV. Not only ALP production processes but also virtual ALP contributions to final states with top quarks are considered in detail. We show how searches through resonant production, such as ALP production in association with a $$ t\overline{t} $$

Published: June 2024

AbstractThe importance of creating eco-friendly and health-conscious materials has become paramount in striving to attain long-term development goals. For the past decades, constant efforts have been made to tackle the issue of formaldehyde release from wood-based panels which, to date, are still mainly produced from unsustainable synthetic adhesives. In the pursuit of sustainable and environmentally responsible adhesive solutions for the wood industry, sodium bisulfate, sodium bisulfite, and sodium nitrite were used under different heat treatment conditions as crosslinkers for canola protein-based bio-adhesive formulations. The developed adhesive formulations showed outstanding mechanical properties, with a viscosity below 4000 mPa/s despite the relatively high solid content, as well as excellent bonding performances. The one-layer particleboards bonded with the canola-based adhesive demonstrated outstanding mechanical properties, with the internal bonding and the bending strength values surpassing 0.60 N/mm2 and 10 N/mm2, respectively. Notably, the sodium nitrite-crosslinked variants exhibited significantly superior performance compared to the UF-bonded control boards. Longer incubation times generally improve bonding strength, with sodium nitrite showing the most pronounced effects. The results of this research showcase not only the possibility of developing a plant protein-based wood adhesive with high solid content, but also the potential superiority of canola protein-based wood adhesives when compared to conventional, synthetic counterparts. These findings offer valuable insights for optimizing bio-based adhesives in wood composite manufacturing, highlighting sodium nitrite as a promising crosslinker for enhancing the adhesive’s performance.
Sex hormone binding globulin (SHBG) modulates mitochondrial dynamics in PPARγ-depleted equine adipose derived stromal cells

Abstract
Peroxisome proliferator-activated receptor gamma (PPARγ) is a transcription factor that promotes adipogenesis, lipid uptake and storage, insulin sensitivity, and glucose metabolism. Hence, defects in PPARγ have been associated to the development of metabolic disorders. Sex hormone-binding globulin (SHBG) is a glycoprotein primarily produced in the liver that regulates the bioavailability of sex hormones. Alike PPARγ, low SHBG levels have been correlated with insulin resistance and associated endocrine abnormalities. Therefore, this study aimed to verify whether SHBG may restore depleted PPARγ functions and thus serve as a new candidate for the management of metabolic conditions. A model of equine adipose-derived stromal cells (EqASCs) has been used, in which a PPARγ silencing and SHBG treatment have been achieved to determine the changes in cell viability, premature senescence, oxidative stress, and mitochondrial functions. Obtained data demonstrated that loss in PPARγ triggers cell apoptosis which is not reversed by SHBG application. Moreover, PPARγ knockdown cells exhibited premature senescence, which has been substantially alleviated by SHBG concomitantly to increased BAX/BCL2 ratio, suggesting a possible effect on senescence-induced apoptosis resistance. Interestingly, PPARγ silencing induced a significant alteration in mitochondrial membrane potential as well as the expression of dynamics and metabolism-related markers. SHBG treatment enabled to ameliorate the transmembrane potential, to normalize the expression levels of key dynamics and metabolism mediators, and to restore the protein levels of PINK, which is critically involved in mitochondria recycling machinery. Presented data suggest that SHBG may provide new mechanistic insights into the regulation of PPARγ functions, and thus offers a preliminary picture on a possible SHBG-PPARγ metabolic crosstalk.

Key messages

PPARγ is a transcription factor that tightly regulates cell metabolism.

Low SHBG levels correlate with insulin resistance and associated endocrine abnormalities.

PPARγ silencing reduces cell viability, triggers premature senescence and profound mitochondrial failure in equine ASCs.

SHBG protein reverses senescent phenotype and apoptosis resistance of PPARγ- ASCs.

SHBG improves mitochondrial dynamics and metabolism following PPARγ knockdown.

SHBG might serve as a PPARγ potential mimicking agent for the modulation of ASCs metabolic processes.
Existence of generating families on Lagrangian cobordisms
Authors: Li Wenyuan 
Published: June 2024

AbstractFor an embedded exact Lagrangian cobordism between Legendrian submanifolds in the 1-jet bundle, we prove that a generating family linear at infinity on the Legendrian at the negative end extends to a generating family linear at infinity on the Lagrangian cobordism after stabilization if and only if the formal obstructions vanish. In particular, a Lagrangian filling with trivial stable Lagrangian Gauss map admits a generating family linear at infinity.
The previously undescribed variant of the thyrohyoid muscle and its potential impact on surgical procedures

Published: June 2024

AbstractThe thyrohyoid muscle belongs to the infrahyoid group located in the carotid triangle. It normally originates from thyroid cartilage and inserts into hyoid bone. Quite often, it is continuous with the sternohyoid muscle. Furthermore, there are variants that have their origin in the cricoid cartilage only, however, this occurs very rarely. During anatomical dissection, a two-headed variant of this muscle was found. One head had its origin in the cricoid cartilage and the other in the thyroid cartilage. This variant of thyrohyoid had not been previously described in the available literature. Therefore, we believe that it may be referred to as the cricothyrohyoid muscle. As the thyrohyoideus is often used as a landmark during surgical procedures in the prelaryngeal area and as a muscle graft, a thorough knowledge of its anatomy and variation is extremely important. We speculate that the two-headed version of this muscle may be problematic during surgical procedures in this region, however, it may also provide more options as a muscular graft.
MOAAA/D: a decomposition-based novel algorithm and a structural design application
Authors: Altiok Mustafa , Gündüz Mesut 
Published: June 2024

AbstractWhen real-world engineering challenges are examined adequately, it becomes clear that multi-objective need to be optimized. Many engineering problems have been handled utilizing the decomposition-based optimization approach according to the literature. The performance of multi-objective evolutionary algorithms is highly dependent on the balance of convergence and diversity. Diversity and convergence are not appropriately balanced in the decomposition technique, as they are in many approaches, for real-world problems. A novel Multi-Objective Artificial Algae Algorithm based on Decomposition (MOAAA/D) is proposed in the paper to solve multi-objective structural problems. MOAAA/D is the first multi-objective algorithm that uses the decomposition-based method with the artificial algae algorithm. MOAAA/D, which successfully draws a graph on 24 benchmark functions within the area of two common metrics, also produced promising results in the structural design problem to which it was applied. To facilitate the design of the "rectangular reinforced concrete column" using MOAAA/D, a solution space was derived by optimizing the rebar ratio and the concrete quantity to be employed.
