Abstract
Key message
In Cyrtanthus mackenii, development of embryo and endosperm were differentially affected by fertilization of male gametes with DNA damage and mutations.

Abstract
Pollen irradiation with ionizing radiations has been applied in plant breeding and genetic research, and haploid plant induction has mainly been performed by male inactivation with high-dose irradiation. However, the fertilization process of irradiated male gametes and the early development of embryo and endosperm have not received much attention. Heavy-ion beams, a type of radiation, have been widely applied as effective mutagens for plants and show a high mutation rate even at low-dose irradiation. In this study, we analyzed the effects of male gametes of Cyrtanthus mackenii irradiated with a carbon-ion beam at low doses on fertilization. In immature seeds derived from the pollination of irradiated pollen grains, two types of embryo sacs were observed: embryo sac with a normally developed embryo and endosperm and embryo sac with an egg cell or an undivided zygote and an endosperm. Abnormalities in chromosome segregation, such as chromosomal bridges, were observed only in the endosperm nuclei, irrespective of the presence or absence of embryogenesis. Therefore, in Cyrtanthus, embryogenesis is strongly affected by DNA damage or mutations in male gametes. Moreover, various DNA contents were detected in the embryo and endosperm nuclei, and endoreduplication may have occurred in the endosperm nuclei. As carbon-ion irradiation causes chromosomal rearrangements even at low doses, pollen irradiation can be an interesting tool for studying double fertilization and mutation heritability.

Published: February 2024

ZusammenfassungEin Trend des Einsatzes von Kunststoffzahnrädern in Getrieben hoher Leistungsdichte ist infolge der zunehmenden Entwicklung von Hochleistungskunststoffen zu beobachten. Simulationsmethoden zur Berechnung des Betriebsverhaltens und Untersuchungen zum Anregungsverhalten von Kunststoffzahnrädern in Leistungsgetrieben sind im Stand der Technik kaum vorhanden. Aktuelle Zahnkontaktanalysen stoßen bei der Berechnung von Kunststoffzahnrädern mit den ihnen zugrunde liegenden linear-elastischen Modellannahmen an ihre Grenzen, da Kunststoffzahnräder ein nichtlineares Materialverhalten aufweisen. Der Bericht umfasst experimentelle und simulative Untersuchungen zum Einfluss der Materialnichtlinearität auf das quasistatische und dynamische Anregungsverhalten von Kunststoffzahnrädern. Um den Einfluss der Materialnichtlinearität infolge einer Temperaturerhöhung auf das Anregungsverhalten zu ermitteln, werden Radvarianten aus ausferritischem Gusseisen mit Kugelgraphit (ADI 900) und Polyetheretherketon (PEEK) bei zwei unterschiedlichen Öltemperaturen untersucht. Das experimentell ermittelte quasistatische Anregungsverhalten wird mit Simulationsmethoden aus dem aktuellen Stand der Technik verglichen, um deren Berechnungsgüte zu quantifizieren. Neben einer Berechnung basierend auf einem linear-elastischen Materialmodell wird das quasistatische Anregungsverhalten der Kunststoffzahnräder mit einem nichtlinearen Materialmodell bestimmt. Der Abgleich der Simulationsergebnisse mit den experimentellen Untersuchungen zeigt, dass die Berechnung des quasistatischen Anregungsverhaltens der Kunststoffzahnräder basierend auf einem linear-elastischen Materialmodell zu höheren Abweichungen führt im Vergleich zu einer nichtlinearen Materialmodellierung.

Published: February 2024

AbstractHuman–robot interaction (HRI), which studies the interaction between robots and humans, appears as a promising research idea for the future of smart factories. In this study, HoloLens as ground control station (HoloGCS) is implemented, and its performance is discussed. HoloGCS is a mixed reality-based system for controlling and monitoring unmanned aerial vehicles (UAV). The system incorporates HRI through speech commands and video streaming, enabling UAV teleoperation. HoloGCS provides a user interface that allows operators to monitor and control the UAV easily. To demonstrate the feasibility of the proposed systems, a user case study (user testing and SUS-based questionnaire) was performed to gather qualitative results. In addition, throughput, RTT, latency, and speech accuracy were also gathered and analyzed to evaluate quantitative results.

Published: February 2024

Abstract
Purpose
To assess the available evidence to support a genetic contribution and define the role of common and rare variants in tinnitus.

Methods
After a systematic search and quality assessment, 31 records including 383,063 patients were selected (14 epidemiological studies and 17 genetic association studies). General information on the sample size, age, sex, tinnitus prevalence, severe tinnitus distribution, and sensorineural hearing loss was retrieved. Studies that did not include data on hearing assessment were excluded. Relative frequencies were used for qualitative variables to compare different studies and to obtain average values. Genetic variants and genes were listed and clustered according to their potential role in tinnitus development.

Results
The average prevalence of tinnitus estimated from population-based studies was 26.3% for any tinnitus, and 20% of patients with tinnitus reported it as an annoying symptom. One study has reported population-specific differences in the prevalence of tinnitus, the white ancestry being the population with a higher prevalence. Genome-wide association studies have identified and replicated two common variants in the Chinese population (rs2846071; rs4149577) in the intron of TNFRSF1A, associated with noise-induced tinnitus. Moreover, gene burden analyses in sequencing data from Spanish and Swede patients with severe tinnitus have identified and replicated ANK2, AKAP9, and TSC2 genes.

Conclusions
The genetic contribution to tinnitus is starting to be revealed and it shows population-specific effects in European and Asian populations. The common allelic variants associated with tinnitus that showed replication are associated with noise-induced tinnitus. Although severe tinnitus has been associated with rare variants with large effect, their role on hearing or hyperacusis has not been established.

AbstractPlant probiotics are live microbial cells or cultures that support plant growth and control plant pathogens through different mechanisms. They have various effects on plants, including plant growth promotion through the production of indole acetic acid (IAA), biological control activity (BCA), and production of cellulase enzymes, thus inducing systemic resistance and increasing the availability of mineral elements. The present work aimed to study the potential of Achromobacter marplatensis and Bacillus velezensis as plant probiotics for the field cultivation of potatoes. In vitro studies have demonstrated the ability of selected probiotics to produce IAA and cellulase, as well as antimicrobial activity against two plant pathogens that infect Solanum tuberosum as Fusarium oxysporum and Ralstonia solanacearum under different conditions at a broad range of different temperatures and pH values. In vivo study of the effects of the probiotics A. marplatensis and B. velezensis on S. tuberosum plants grown in sandy clay loamy soil was detected after cultivation for 90 days. Probiotic isolates A. marplatensis and B. velezensis were able to tolerate ultraviolet radiation (UV) exposure for up to two hours, the dose response curve exhibited that the D10 values of A. marplatensis and B. velezensis were 28 and 16 respectively. In the case of loading both probiotics with broth, the shoot dry weight was increased significantly from 28 in the control to 50 g, shoot length increased from 24 to 45.7 cm, branches numbers increased from 40 to 70 branch, leaves number increased from 99 to 130 leaf, root dry weight increased from 9.3 to 12.9 g, root length increased from 24 to 35.7 cm, tuber weight increased from 15 to 37.0 g and tubers number increased from 9 to 24.4 tuber, the rot percentage was reduced to 0%. The addition of both probiotic isolates, either broth or wheat grains load separately has enhanced all the growth parameters; however, better results and increased production were in favor of adding probiotics with broth more than wheat. On the other hand, both probiotics showed a remarkable protective effect against potato pathogens separately and reduced the negative impact of the infection using them together.

AbstractConserving large mammals on small islands poses a great challenge, given their high resource demand within the limited space available. The endangered Togean Islands babirusa (Babyrousa togeanensis) is one of these species, with a distribution range limited to four small islands in the Togean Archipelago, Indonesia. Despite being listed as endangered, very little information is available on the distribution and ecology of this species. To address this critical knowledge gap, we here report the first field-based ecological study of the Togean Islands babirusa across its entire distribution range. Following a stratified random sampling procedure, we distributed camera traps at 103 stations across four islands to collect data on the species distribution from July-October 2022. We performed an occupancy modeling analysis to assess the species’ habitat use, with various habitat features estimated through remote sensing and field measurements as covariates. We found that forest and mangrove availability over a large area positively influenced babirusa habitat selection. Babirusas only made use of agricultural areas when large forest areas were available nearby. Our results highlight the benefits of redesigning the national park area to accommodate babirusa habitat requirements, specifically by reassigning the non-forested park areas (about 30% of the park area) to non-protected forests currently outside the park boundary (about 50% of total forested area). Our case study exemplifies key challenges associated with conserving large mammals on small islands and highlights the importance of following an adaptive management approach, which in this case implies shifting 30% of the current protected area.
Determination of suitable agricultural areas and current land use in Isparta Province, Türkiye, through a linear combination technique and geographic information systems
Authors: Demir Sinan 
Published: February 2024

AbstractSustainable land use is vital for the increasing population’s food supply and global food security. The use of the soils in the world for agricultural purposes makes a significant contribution to both national and international food supply, while the remaining plays a crucial role in maintaining forested and semi-natural ecosystems. For this reason, it is important to determine suitable agricultural areas. Soils in the study area are used for agricultural areas at 27.49%, while 63.17% are designated for forest and semi-natural areas. This study’s aim is to locate suitable agricultural areas in the semiarid Isparta province using the linear combination technique (LCT), a multi-criteria analysis method that uses topographic data and national soil data. The weights of the parameters were determined using the analytic hierarchy process (AHP). The agricultural land suitability map generated by LCT was divided into five categories according to the land suitability classification determined by the United Nations Food and Agriculture Organization (FAO). It has been determined that 39.52% of the study area is for highly suitable (S1), moderately suitable (S2), and marginally suitable (S3) classes in the map of suitable agricultural areas using LCT. It is determined that 3991.24 ha of land in the S1 class, which shows the highly suitable areas for agriculture in the study area, was used as artificial surfaces. The results showed that the misuse of suitable agricultural lands increased in the study area. It was determined that artificial areas are expanding into agricultural areas, according to the CLC 2018 database. It shows that soil survey and mapping studies should be carried out according to soil classification systems such as Soil Taxonomy 2022, Land Use/Land Cover Area Frame Survey (LUCAS), and World Reference Base (WRB) 2022, for the determination and use of suitable agricultural lands in Türkiye.

Published: February 2024

AbstractPurposeMyopia is controlled optically with peripheral defocus spectacles, multifocal contact lenses, or orthokeratology lenses. However, it is unknown which optical correction will improve visual performance. This scoping review aimed to identify and summarize studies on various visual functions using optical corrections for myopia control.MethodsTo develop the search strategy, population (Myopia), concept (visual performance), and context (unrestricted race/region) were used. PubMed, SCOPUS, Cochrane Library, and Web of Science databases were searched using the keywords myopia, contrast sensitivity, high and low contrast visual acuity, stereopsis, and optical correction of myopia control. This scoping review protocol was registered in the Open Science Framework registry and followed the framework for scoping review outlined by the Joanna Briggs Institute.ResultsEight studies (n = 8) met the inclusion criteria and were included in the review. Four were conducted in Europe, two were conducted in China, and one was conducted in Japan and Singapore. Five studies were randomized controlled trials, out of which three used contact lenses and two studies used peripheral defocus spectacles lenses. Studies ranged from one day to 2 years. Three studies that used orthokeratology lenses were prospective study designs. Among the studies that used orthokeratology lenses and contact lenses, two studies measured the contrast sensitivity function with CSV1000 (Vector Vision) under mesopic and photopic conditions, with and without glare. Two studies measured the central and peripheral contrast sensitivity using psychophysics experiments. High and low contrast visual acuity was measured using the Freiburg Vision Test (n = 1) and ETDRS charts (n = 3), and stereopsis was assessed using a random dot stereogram (n = 1). The studies showed a reduction in central and peripheral contrast sensitivity function and low contrast acuity when treated with multifocal contact lenses, orthokeratology lenses, and peripheral defocus lenses compared with single-vision lenses.ConclusionThis scoping review found a reduction in central and peripheral contrast sensitivity function, as well as low contrast visual acuity when using various optical corrections for myopia control, while high-contrast visual acuity remained the same. The impact of visual functions may not influence the effectiveness of myopia control. Eye care practitioners should provide awareness to the parent and patient population about the potential visual impact of recent designs for optical corrections of myopia control.

Abstract
Purpose
To examine the ophthalmic data from a large database of people attending a general medical survey institute, and to investigate ophthalmic findings of the eye and its adnexa, including differences in age and sex.

Methods
Retrospective analysis including medical data of all consecutive individuals whose ophthalmic data and the prevalences of ocular pathologies were extracted from a very large database of subjects examined at a single general medical survey institute.

Results
Data were derived from 184,589 visits of 3676 patients (mean age 52 years, 68% males). The prevalence of the following eye pathologies were extracted. Eyelids: blepharitis (n = 4885, 13.3%), dermatochalasis (n = 4666, 12.7%), ptosis (n = 677, 1.8%), ectropion (n = 73, 0.2%), and xanthelasma (n = 160, 0.4%). Anterior segment: pinguecula (n = 3368, 9.2%), pterygium (n = 852, 2.3%), and cataract or pseudophakia (n = 9381, 27.1%). Cataract type (percentage of all phakic patients): nuclear sclerosis (n = 8908, 24.2%), posterior subcapsular (n = 846, 2.3%), and capsular anterior (n = 781, 2.1%). Pseudophakia was recorded for 697 patients (4.6%), and posterior subcapsular opacification for 229 (0.6%) patients. Optic nerve head (ONH): peripapillary atrophy (n = 4947, 13.5%), tilted disc (n = 3344, 9.1%), temporal slope (n = 410, 1.1%), ONH notch (n = 61, 0.2%), myelinated nerve fiber layer (n = 94, 0.3%), ONH drusen (n = 37, 0.1%), optic pit (n = 3, 0.0%), and ON coloboma (n = 4, 0.0%). Most pathologies were more common in males except for ONH, and most pathologies demonstrated a higher prevalence with increasing age.

Conclusions
Normal ophthalmic data and the prevalences of ocular pathologies were extracted from a very large database of subjects seen at a single medical survey institute.
A note on Sen’s representation of the Gini coefficient: Revision and repercussions
Authors: Stark Oded 
Published: February 2024

AbstractSen (1973 and 1997) presents the Gini coefficient of income inequality in a population as follows. “In any pair-wise comparison the man with the lower income can be thought to be suffering from some depression on finding his income to be lower. Let this depression be proportional to the difference in income. The sum total of all such depressions in all possible pair-wise comparisons takes us to the Gini coefficient.” (This citation is from Sen 1973, p. 8.) Sen’s verbal account is accompanied by a formula (Sen 1997, p. 31, eq. 2.8.1), which is replicated in the text of this note as equation (1). The formula yields a coefficient bounded from above by a number smaller than 1. This creates a difficulty, because the “mission” of a measure of inequality defined on the unit interval is to accord 0 to perfect equality (maximal equality) and 1 to perfect inequality (maximal inequality). In this note we show that when the Gini coefficient is elicited from a neat measure of the aggregate income-related depression of the population that consists of the people who experience income-related depression, then the obtained Gini coefficient is “well behaved” in the sense that it is bounded from above by 1. We conjecture a reason for a drawback of Sen’s definition, and we present repercussions of the usage of the “well-behaved” Gini coefficient.
Backcrossing Modulates the Metabolic Profiles of Anthocyanin-Pigmented ‘Vitamaize’ Lines Derived from Elite Maize Lines
Authors: Peniche-Pavía Héctor Arturo , González-Rodríguez Tzitziki , Tiessen Axel , García-Lara Silvero , Winkler Robert 
Published: February 2024

AbstractVitamaize lines (VMLs) were created by backcrossing the pigmented aleurone trait into Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) maize lines (CMLs). This study evaluates metabolic differences between the VMLs and their original CMLs. Direct infusion mass spectrometry (DIMS) analyses, carotenoid profiling, total anthocyanins content (TAC) determination, and biochemical evaluation of the quality protein maize (QPM) endosperm trait allowed a comprehensive chemical characterization of the maize lines. DIMS data indicate higher hexoses and trigonelline content for most VMLs; the carotenoid profile revealed a decrease in β-cryptoxanthin to less than half of the original parent content for two VMLs but an augmentation for one VML. The pigmented aleurone VMLs did not inherit the complex QPM endosperm trait of the QPM CMLs. Except for anthocyanin accumulation, no other metabolites were consistently modified across all the backcross-generated maize lines with a pigmented aleurone trait. These findings suggest using genetic or metabolic markers rather than morphological or visual traits for future breeding programs.
Imprinting parental signals: a key driver of network status for new spinoff firms

Published: February 2024

AbstractAlthough past research has firmly established the positive effects of network status for resource acquisition and success in entrepreneurial endeavors, we still have a fragmented, limited understanding of the actual drivers of network status emergence. Prior research has mainly focused on the post-founding phase, pointing to the importance of current employment–based and firm-level affiliations in new ventures for their future status formation. In this paper, we extend the attention to the pre-founding phase in a study of spinoffs. Building on imprinting and signaling theories, we theorize that coming from a highly reputable parent firm has a long-term positive impact on a spinoff’s subsequent status by signaling a young spinoff firm’s quality to external parties. We advance previous research by further theorizing that such imprinting is contingent on the level of knowledge relatedness between the parent and spinoff as well as on whether there exists a strategic alliance between them post-founding. In addition, we argue a positive three-way interaction among parent reputation, parent-spinoff knowledge relatedness, and the parent-spinoff strategic alliance. Our analysis of a comprehensive longitudinal sample of 162 Australian mining spinoffs (i.e., firms started by ex-employees of incumbent parent firms) and 3405 strategic alliances from 2001 to 2014 supports majority of our hypotheses.
