Published: August 2022

Introduction

The working environment abroad a ship is unique, with constant stimuli such as rolling of the vessel, noise, and vibration. Fishing industry is important for Icelandic economy, still the effect of seasickness-related symptoms on seamen´s health is not fully understood. Thus, the objective of this study is to explore the impact of seasickness-related symptoms, i.e., seasickness, seasickness symptoms and mal de débarquement on seaman´s health, and how their working environment may affect those factors.

Methods

Cross-sectional data was collected from 262 seamen answering questionnaire. Majority of the seamen participated while attending a compulsory course held by the Maritime Safety and Survival Training Centre. The majority of participants were men. A chi-square test was used to detect the difference between variables.

Results

The majority of seamen had experienced seasickness (87.8%) or mal de débarquement (85.8%). Having a history of tension headache (38.1%) and tinnitus (37.9%) was quite common. A total of 30.6% of the participants had been admitted to hospital once or more due to mishaps or accidents on land.

Discussion

Seasickness and seasickness symptoms together with mal de débarquement are common in Icelandic seamen. Working conditions at sea are demanding and seam to affect the seamen´s health both at sea and ashore, making further research needed.

Mitochondrial respirometry is key to understand how environmental factors model energetic cellular process. In the case of ectotherms, thermal tolerance has been hypothesized to be intimately linked with mitochondria capability to produce enough adenosine triphosphate (ATP) to respond to the energetic demands of animals in high temperatures. In a recent study made in Octopus maya was proposed the hypothesis postulating that high temperatures could restrain female reproduction due to the limited capacity of the animals’ heart to sustain oxygen flow to the body, affecting in this manner energy production in the rest of the organs, including the ovarium Meza-Buendia AK et al. (2021). Unfortunately, until now, no reports have shown temperature effects and other environmental variables on cephalopod mitochondria activity because of the lack of a method to evaluate mitochondrial respiratory parameters in those species’ groups. In this sense and for the first time, this study developed a method to obtain mitochondrial respirometry data of adult Octopus maya’s heart. This protocol illustrates a step-by-step procedure to get high yield and functional mitochondria of cephalopod heart and procedure for determining the corresponding respiratory parameters. The procedure described in this paper takes approximately 3 to 4 hours from isolation of intact mitochondria to measurement of mitochondrial oxygen consumption.
The impact of migration characteristics on rural migrant households’ farmland use arrangements in China
Authors: Lu Chong , Wu Ailin
Published: August 2022

This paper investigates the impacts of migration characteristics on rural migrant households’ farmland use arrangements in China. The results reveal that trailing migration, duration of migration and the proportion of co-migrants have a significant effect on the probability of rural migrant households’ farmland abandonment. Commercial employment migration has a negative impact on the abandonment of farmland by migrant families. Migrant households are most likely to choose farmland abandonment in the western and middle regions of China and in small farmland areas. In the eastern region, and first tier and second tier Chinese cities, migrant households are more inclined to choose farmland transfer. Household earnings increase, which induces households to gradually give up the cultivation of farmland or to transfer farmland, constituting a mechanism in Chinese households’ farmland use arrangements. Notably, the consolidation of arable land should be the focus in areas of low economic development. Furthermore, an effective mechanism for the transfer of farmland should be established.

Published: August 2022

Software-defined networks offer a new approach that attracts the attention of most academic and industrial circles due to the features it contains. However, some loopholes make such modern networks vulnerable to many types of attacks. Among the most important types of these attacks is the Distributed Denial of Service (DDoS) attack, which in turn affects the network’s performance and delays many real user requests. As one of the main features of SDN is the centralization of all the control plane in the SDN controller, it becomes a central point of attack that may compromise the whole network. Hence, in our proposed approach, we aim to mitigate the DDoS attack that maybe launched to compromise the SDN controller, flood the control plane and cripple the entire network. Many DDoS mitigation scheme have been proposed, however, determining the threshold between legitimate requests and malicious requests is still a challenging task. Our proposed approach relies on a two-phases algorithm that assigns a variable trust value for every user. This trust value is compared with schemes relying on a threshold value that changes dynamically and assists in detecting the DDoS attack. The first phase of our two-phases algorithm is Header fields extraction, and the second phase is calculating the trust value based on header fields information. Our proposed approach shows better performance than related detection schemes in terms of accuracy, detection rate, and false-positive rate. Where the accuracy of the system reaches up to 98.83% which is high compared to other traditional methods.

Published: August 2022

This study aimed to identify concerns related to returning to the Nagadoro district of Iitate Village, Fukushima Prefecture, Japan, in 2023 among its residents as it is designated as a difficult-to-return zone after the Fukushima Daiichi nuclear power plant accident. The following four concerns were extracted from the interviews and qualitative analysis: “Difficulties in restarting/continuing farming,” which represent the difficulties in making a living from agriculture due to the absence of family members and neighbors, and the insufficient radiation decontamination; “Discriminatory treatment of products and residents from villagers,” which suggests the presence of discriminations that residents of Nagadoro district are eccentrics and its agricultural products should not be treated together with those of other districts in the Village due to the recognition that the district is severely polluted by radiation; “Shift of the responsibility of returning home from the country to residents by scapegoating,” which is characterized by the shift of responsibility from the government to the residents, including harsh social criticism of the residents of Nagadoro district for not returning even though the evacuation order has been lifted, when it should have been the government’s responsibility to recover the district to a habitable state; “Loss of options for continued evacuation,” which is the loss or weakening of the position of residents of the Nagadoro district who continue to evacuate, and of administrative compensation, resulting from the legal change that they are no longer “evacuees” after the evacuation order is lifted. The findings of this study will provide a foundation for the support of residents of the Nagadoro district after lifting the evacuation order scheduled for the spring of 2023. The findings may be transferable to the residents of other difficult-to-return zones expected to be lifted after the Nagadoro district and to also a radiation disaster-affected place in the future.

Aim

To identify the molecular basis of Congenital Hereditary Endothelial Dystrophy CHED caused by mutations in SLC4A11, in the consanguineous Pakistani families.

Methods

A total of 7 consanguineous families affected with Congenital Hereditary Endothelial Dystrophy were diagnosed and registered with the help of ophthalmologists. Blood samples were collected from affected and unaffected members of the enrolled families. Mutational analysis was carried out by DNA sequencing using both Sanger and Whole Exome Sequencing (WES). Probands of each pedigree from the 7 families were used for WES. Results were analyzed with the help of different bioinformatics tools.

Results

The sequencing results demonstrated three known homozygous mutations in gene SLC4A11 in probands of 7 families. These mutations p.Glu675Ala, p.Val824Met, and p.Arg158fs include 2 missense and 1 frameshift mutation. The mutations result in amino acids that were highly conserved in SLC4A11 across different species. The mutations were segregated with the disease phenotype in the families.

Conclusion

This study reports 3 mutations in 7 families. One of the pathogenic mutations (p.R158fs) was identified for the first time in the Pakistani population. However, two mutations (p.Glu675Ala, p.Val824Met) were previously reported in two and one Pakistani family respectively. As these mutations segregate with the disease phenotype and bioinformatics tool also liable them as pathogenic, they are deemed as probable cause of underlying disease.

Authors: Lawrie Louisa , Gillies Katie , Duncan Eilidh , Davies Loretta , Beard David , Campbell Marion K.
Published: August 2022

Background

Implementation of Robotic Assisted Surgery (RAS) is complex as it requires adjustments to associated physical infrastructure, but also changes to processes and behaviours. With the global objective of optimising and improving RAS implementation, this study aimed to: 1) Explore the barriers and enablers to RAS service adoption, incorporating an assessment of behavioural influences; 2) Provide an optimised plan for effective RAS implementation, with the incorporation of theory-informed implementation strategies that have been adapted to address the barriers/enablers that affect RAS service adoption.

Methods

Semi-structured interviews were conducted with RAS personnel and stakeholders, including: surgeons, theatre staff, managers, industry representatives, and policy-makers/commissioners. The Theoretical Domains Framework (TDF) and the Consolidated Framework for Implementation Research (CFIR) was used to identify barriers and enablers that represent individual behaviours, capabilities, attitudes, beliefs, and external organisational factors that influence the implementation of RAS.

Results

Findings suggest that implementation planning has three separate phases–pre-, early, and late implementation. For pre-implementation, barriers and enablers identified included the cost of RAS equipment and issues of economic viability, weak outcome evidence for RAS, a preponderance of an eminence driven model, the clinician/manager relationship, and views around the uptake and expansion of RAS in the future. Early implementation findings revealed role changes for theatre personnel and an enhanced team approach, reliance on industry for training provision, and changes in skill sets and attentional processes. Late implementation factors included equipment maintenance costs, technological limitations, changes to cognition during RAS routine use, and benefits to institutions/healthcare professionals (such as ergonomic improvement).

Conclusion

Together, findings suggest the factors that affect RAS implementation are multi-faceted and change across the life-cycle of intervention adoption. Theory-informed strategies are suggested which can optimise implementation of RAS. Optimisation strategies need planning from the outset.

Published: August 2022

Background

The awareness of women towards oral health during pregnancy is an important aspect of her general health. It can compromise pregnancy outcomes, as well as it may affect the newborn’s overall health. Every pregnant woman plays a critical role in shaping the oral hygiene habits adopted by her if she is aware of pregnancy-related oral health and result in good perinatal outcomes. This study aimed to assess knowledge of oral health during pregnancy and associated factors among pregnant mothers who attend antenatal care at South Omo Zone public hospitals, Southern Ethiopia, 2021.

Methods

An institution-based cross-sectional study was conducted among pregnant women attending routine antenatal care from October 01 to November 30. A systematic random sampling method was conducted to select study participants. Data had been collected through face-to-face interviews using semi-structured questionnaires. Data were entered using epi data version 3.1 and exported to Statistical Package for the Social Sciences version 25 for data analysis. Descriptive statistics had calculated for each variable, and binary logistic regression analysis with 95% confidence intervals was carried out to assess the factors associated with the outcome variables. Variables with P-value less than 0.05 were used to declare statistical significance.

Result

Overall good knowledge of pregnant mothers regarding oral health was 34.1% with 95% CI, (32.76, 35.44). Having access to health facility (AOR = 2.60, 95% CI, 1.44, 4.70), having the educational status of secondary and above (AOR 1.37, 95% CI, 1.44, 4.31), having the educational status of primary education (AOR = 0.43, 95% CI, 0.20, 0.92), having a median income of > = 1500 Ethiopian birr (AOR = 0.41, 95% CI, 0.23, 0.72), being governmental employee (AOR = 0.11, 95% CI, 0.03, 0.41), received oral health hygiene counseling during pregnancy (AOR = 1.33, 95% CI, 1.62, 2.84) were significantly associated with good knowledge of oral health of pregnant mothers.

Conclusion

This study showed that the knowledge of pregnant mothers about oral health was 34.1%. Educational status, monthly income, occupation, access to health services, and receiving counseling on oral hygiene at antenatal care were some factors associated with good knowledge of oral health during pregnancy. Therefore strengthening counseling during antenatal care, improving access to a health facility, improving educational status, monthly income, and being government employee are crucial to enhance knowledge of women towards oral health during pregnancy.
A scoping review protocol to elucidate outcomes following abiraterone versus enzalutamide for prostate cancer
Authors: Shah Yash B. , Shaver Amy L. , Kelly William Kevin , Lu-Yao Grace
Published: August 2022

Introduction

Abiraterone acetate and enzalutamide are commonly employed in prostate cancer therapy in an interchangeable manner. These drugs are highly efficacious in androgen antagonism to improve patient outcomes, but they also carry noteworthy risk of adverse effects. Common toxicities vary amongst the two drugs and may have differential interactions with patient co-morbidities, but these patterns are unclear as co-morbidities typically serve as exclusion criteria in clinical trials. Hence, there is no existing guidance on how clinicians may tailor treatment based on patient-specific factors. Analysis of differential patient outcomes between these two drugs can inform future systematic reviews, new clinical studies, and clinical decision making.

Method and analysis

The framework for this methodology was informed by the Joanna Briggs Institute methodology for scoping reviews. Title and abstract screening will be performed by two independent researchers to create an initial study inventory. This will be followed by full-text screening for study inclusion. Population-based studies describing patient outcomes, common toxicities, and associations with patient co-morbidities following abiraterone or enzalutamide therapy will be included. After data is extracted, it will be summarized for presentation.

Ethics and dissemination

The findings of this scoping review will be published in a peer-reviewed journal. The results will be used to inform future studies on patient-specific factors informing treatment choice between abiraterone and enzalutamide for castration-resistant prostate cancer. All data are from published openly accessible sources, and therefore, no ethical clearance is necessary. The protocol is also registered at https://doi.org/10.6084/m9.figshare.19149227.

In vivo bioluminescence imaging facilitates the non-invasive visualization of biological processes in living animals. This system has been used to track virus infections mostly in mice and ferrets; however, until now this approach has not been applied to pathogens in avian species. To visualize the infection of an important avian pathogen, we generated Marek’s disease virus (MDV) recombinants expressing firefly luciferase during lytic replication. Upon characterization of the recombinant viruses in vitro, chickens were infected and the infection visualized in live animals over the course of 14 days. The luminescence signal was consistent with the known spatiotemporal kinetics of infection and the life cycle of MDV, and correlated well with the viral load measured by qPCR. Intriguingly, this in vivo bioimaging approach revealed two novel sites of MDV replication, the beak and the skin of the feet covered in scales. Feet skin infection was confirmed using a complementary fluorescence bioimaging approach with MDV recombinants expressing mRFP or GFP. Infection was detected in the intermediate epidermal layers of the feet skin that was also shown to produce infectious virus, regardless of the animals’ age at and the route of infection. Taken together, this study highlights the value of in vivo whole body bioimaging in avian species by identifying previously overlooked sites of replication and shedding of MDV in the chicken host.

Nutrition plays a pivotal role in the development of an organism. Drosophila melanogaster is an important model for nutritional research. The nutritional composition of semolina-jaggery diet and its effect on some developmental aspect of Harwich strain D. melanogaster was studied. Semolina- jaggery diet, which are product of wheat endosperm and cane sugar respectively are rich in carbohydrate, protein, and dietary sugars. Semolina-jaggery diet was prepared in 5%, 10% and 15% with corn flour diet as the control group. 15% semolina-jaggery had the highest percentage carbohydrate (15.12±0.30) while highest protein content was recorded in control diet (3.46±0.08). Fecundity of D. melanogaster reared on semolina-jaggery diet varied across days with 5% SJ having the highest mean number of eggs. The 10% SJ recorded the highest mean number of offspring across five generations but was lower to the offspring output of control group in all the five generations. The nutritional composition in the varying percentages of semolina-jaggery diet had significant effect on the egg laying and offspring output of Harwich strain Drosophila melanogaster.
The Impact of Collateralization on Derivative Valuation
Authors: Xiao Tim
Published: August 2022

This paper presents a model for pricing derivatives under collateral posting. Empirically, we find that counterparty risk and collateralization together have high explanatory power on premium spreads. The finding leads to practical implications, such as collateralization modeling allows forecasting credit spread. We also find that credit risk is negatively correlated with collateralization as an increase in collateralization causes a decrease in credit risk. The empirical tests corroborate our theoretical conclusions that collateralization can reduce CVA charges and mitigate counterparty risk.

Sömürge geçmişine sahip ülkelerin bağımsızlık süreçlerinde talep ettikleri siyasal değişiklikler, tarihsel gerçeklikleri doğrultusunda şekillenmektedir. Siyasi değişim talepleri, egemenlik aygıtlarının değişimi olarak yoğunlaşmış ve ağırlıklı olarak siyasi taleplere ulaşma konusunda ideolojiler belirleyici olmuştur. Taleplere ulaşmak için milliyetçilik önemli bir yere sahiptir. Milliyetçilik, modern nitelikleri olan ve talepleri karşılama kapasitesi bakımından da ideolojik olarak modernliği ile işlevsel unsurlar taşıyan bir kavramdır. Özellikle siyasal iktidar taleplerini gerçekleştirmek için kullanılan araçlardan biri milliyetçiliktir. Bir diğer araç ise, söz konusu ideoloji çerçevesinde tercih edilen uygulamaların hayata geçirilmesinde kullanılan siyasal şiddettir. Milliyetçilik ve siyasal şiddet, araçsal ilişkileri açısından, karşılıklı çıkar kümeleri oluşturan ve birbirini besleyen olgulardır. Bu olguların bir arada yaşandığı yerlerden biri Sri Lanka olmuştur. Çalışma, Sri Lanka’yı ulus devlet modeline yaklaştırmaya çalışan Sinhala etnisi ve kendisine bağımsızlık sonrası ülkede yer açmaya çalışan Tamil etnisinin siyasallaşma eğilimlerinde kullandıkları milliyetçilik ve siyasal şiddet olgularını araçsalcı yaklaşım ile irdelemeyi amaçlamaktadır.

This paper mainly tries to explore the new Model of Indonesian Economic Diplomacy to Non-Traditional Market by Setiawan & Sulastri (2020) with a study case of increasing vegetable oil export to Brazil. Brazil is one of the main targets of Indonesia’s export-development policy to non-traditional markets. The main concern of this paper is how economic diplomacy plays a role in reacting to the declining trend of vegetable oil exports as Indonesia’s leading export product to Brazil during 2016-2020. This paper is a descriptive qualitative research using simple trade calculations to justify Indonesian exports orientation. This paper found there are at least 6 driving factors for the implementation of economic diplomacy, 3 prominent actors for conducting economic diplomacy and 8 processes of economic diplomacy. Indonesia has successfully increased the export trend of vegetable oil to Brazil in the period of 2017-2021, however specific economic diplomacy efforts to encourage vegetable oil exports were identified as minimum.

This study aimed to investigate the factors affecting the smoking rate of regular cigarettes among adolescents in one region of Korea. The ‘smoking rate,' 'smoking experience rate,' 'current smoking rate,' and 'daily smoking rate' for cigarettes were investigated. Smoking probability was calculated according to the presence or absence of smokers in the family, presence or absence of secondhand smoke in the home, presence or absence of witnessing smoking by faculty and staff, presence or absence of secondhand smoke in the school, and experience of secondhand smoke excluding home and school. For the analysis of the results, an odds ratio was calculated using a logistic regression analysis. This study found that, having a smoker in the family, experience of secondhand smoke at home, witnessing smoking by faculty members, and experience of secondhand smoke in school were significant influencing factors.
Interpolation inequalities for partial regularity

We propose two new direct methods for proving partial regularity of
solutions of nonlinear elliptic or parabolic systems. The methods are based
on two similar interpolation inequalities for solutions of linear systems

integrability. We illustrate the methods in detail for the case of a quasilinear elliptic system.
Mullā Ṣadrā on free will and freedom
Authors: Azadani Zakieh
Published: August 2022

Although even before the coming of Islam, a “predestinarian view” could be identified in the Arabic tradition, and so apparently Arabs were not unfamiliar with the conflict between human free will (iḫtiyār) and predestination, after the emergence of Islam and the emphasis of Qurʾān on God’s omnipotence, this question arose more seriously in different forms in the Islamic world. It was during the Umayyad period of Islamic history that the problem of destiny became the subject of discussion between two groups of thought, the so-called Qadariyya and Ǧabriyya, and some questions raised explicitly: If human will is entirely determined by God, how would God’s justice be justified? What would happen to human responsibility for his sins? Adherents of Qadariyya believed that man is free and the agent of his own actions, and so is responsible for his deeds. In contrary, according to Ǧabriyya, man is determined by God in all his actions.
Performance of dual one-way measurements and precise orbit determination for BDSviainter-satellite link

Published: August 2022

The continuous full operation of the constellation of BeiDou navigation satellite system (BDS) provides favorable conditions for the performance evaluation of the BDS inter-satellite links (ISLs). The primary features of ISLs that affect the precision of precise orbit determination (POD) and time synchronization include (i) the spatiotemporal coverage or continuity of observations; (ii) the observational accuracy, such as observation noise and bias; and (iii) the observational geometry represented by dilution of precision. After comparing some technical features and the current status of the Global Navigation Satellite Systems ISLs, the measurement principle of dual one-way ISLs for BDS and its data processing methods are presented. The performance evaluation involving the above three aspects was carried out using 14 days of ISL data, with some typical indicators derived. POD based on data fusion of ISLs and ground-based L-band monitoring stations was conducted, with root-mean-square of posterior residuals of about 5.0 cm, and MEO radial accuracy better than 1.0 cm. The results show that ISLs offer crucial support for BDS to provide global high-precision services under regional monitoring network conditions.
Being and becoming an international student: the inter-relation between language socialization and identities
Authors: Soltani Behnam , Tran Ly , Reza Amir
Published: August 2022

This article draws on Lefebvre’s production of space to understand the cultural negotiations and underlying meanings of being and becoming an international student. Rich and multiple data sources including video/audio recordings of classroom interactions, field notes, interviews, diaries, and institutional documents from a Vietnamese student’s participation in English for Academic Purposes (EAP) and mainstream courses in a New Zealand university (NZU) were drawn upon. The findings of this study show that the student’s engagement in both the new social space and academic environment of NZU is mediated through negotiations and reflections of her Vietnamese-ness and constant comparison of the host culture with that of Vietnam and how her experience of navigating the social space of New Zealand influences her perceptions of Vietnamese-ness.

This study explores the different paths that lead to the effectuation and causation of entrepreneurial decision-making logic. Data were collected from a sample of 300 entrepreneurs in China in January and March 2018 and analyzed using crisp-set qualitative comparative analysis (csQCA). The results reveal various combinations of four key factors, i.e., environmental uncertainty, entrepreneurial experience, organizational slack, and centralization of decision-making factors, determine the effectuation or causation logics. No antecedent condition alone is necessary to produce the outcome, although several factors are identified as sufficient for the presence of effectual or causal decision-making logics. This study advances the entrepreneurship literature by revealing the combinations of factors that Knowledge of how the factors interact in the decision-making process determine entrepreneurial decision-making logic. The study findings can help entrepreneurs to better communicate, discuss and justify their decisions.
Computation and analysis of anisotropic solar radiation model for India
Authors: Makhija Amandeep Singh , Bohra Shabbir S.
Published: August 2022

The solar radiation data are a very important parameter to forecast generation from any solar PV (Photo Voltaic) plant to be installed at a suitable location, though it is not readily available for many locations because of the costly measurement instruments, and their maintenance, and calibration issues. The solar irradiation data available from NASA and Meteonorm has the prediction topology of consolidating 20–25 years old irradiation data which has the question of reliability. Furthermore, at various locations in India, the irradiance value of Meteonorm is overestimated than actual. In this research study an attempt has been made to develop an algorithm for the anisotropic solar radiation model by coalescing Gopinathan empirical parameter, Klucher anisotropic model, and Collares-Pereira & Rabl (GKCR) empirical parameter which gives the best results of forecasted daily and monthly solar radiation at almost every location in India. The computed results are compared with Meteonorm and the NASA database for three distinct locations (New Delhi, Chennai, and Kolkata) at different azimuths and tilt angles. The results obtained i.e., solar tilted radiation and tilt gain were very close to that simulated using PVsyst software using Meteonorm and NASA database. The computed results were compared using various statistical tools with measured irradiance values for four distinctly located solar PV plants. The computed result shows the least error compared to actual data for two locations. Employing the GKCR empirical algorithm mentioned in the research article, hourly irradiance data for the next day, for any specific tilt and azimuth angle can be estimated using available weather forecast data (sunshine duration) and can circumvent the penalty levied by the Load dispatch Centre. Furthermore, by using monthly data anticipated by the algorithm, the question of data reliability of chargeable Meteo sources working on coalescing data of antiquated years like NASA and Meteonorm can be solved.

Published: August 2022

This paper illustrates the design of closed-loop controllers operating High Voltage Back to Back three-phase converter for frequency stabilization and power quality improvement. Simulations of the converter with Multi-frequency control with the proposed Fuzzy-2DOFPI (two degrees of freedom) are carried out in Simulink/MATLAB. Performance parameters such as frequency stabilization and source voltage total harmonic distortion (THD) are considered for comparison of the controllers with conventional ones. The fuzzy-tuned 2DOFPI controller with multi-frequency provides a better result, with a source-voltage THD of 0.23% and acts as a source-side filter for the converter. Finally, the fuzzy-tuned 2DOFPI with multi-frequency controller combination is implemented in an OPAL-RT 5650 real-time simulator for experimental validation of power quality enhancement and frequency stabilization.

Authors: Engel Konrad , Laasch Bastian
Published: August 2022

Let𝒫{\mathcal{P}}be ann-dimensional convex polytope and let𝒮{\mathcal{S}}be a hypersurface inℝn{\mathbb{R}^{n}}. This paper investigates potentials to reconstruct𝒫{\mathcal{P}}, or at least to compute significant properties of𝒫{\mathcal{P}}, if the modulus of the Fourier transform of𝒫{\mathcal{P}}on𝒮{\mathcal{S}}with wave length λ, i.e.,

|∫𝒫e-i⁢1λ⁢𝐬⋅𝐱⁢𝐝𝐱| for ⁢𝐬∈𝒮,\biggl{\lvert}\int_{\mathcal{P}}e^{-i\frac{1}{\lambda}\mathbf{s}\cdot\mathbf{x% }}\,\mathbf{dx}\biggr{\rvert}\quad\text{for }\mathbf{s}\in\mathcal{S},

is given, λ is sufficiently small and𝒫{\mathcal{P}}and𝒮{\mathcal{S}}have some well-defined properties. The main tool is an asymptotic formula for the Fourier transform of𝒫{\mathcal{P}}with wave length λ whenλ→0{\lambda\rightarrow 0}. The theory of X-ray scattering of nanoparticles motivates this study, since the modulus of the Fourier transform of the reflected beam wave vectors is approximately measurable on a half sphere in experiments.

In this study, a sustainable filler made from papyrus fiber ash (PFA) is used as a partial cement replacement in hot mix asphalt mixtures (HMA). The replacement levels used are 0, 5, 10, and 15% by weight of ordinary Portland cement. The hot mix asphalt samples were subjected to Marshal volumetric properties (stability, flow, and air voids) and service tests (tensile strength ratio test and immersion compression test) to predict the influence of the used filler modifier on the moisture sensitivity of blended HMA. Best results have been achieved by using 10% of PFA, whereas all the prepared samples with the mentioned percentage of the filler modifier showed a lower sensitivity to moisture in comparison with the control samples, which contained 0% of PFA. The used technique proved to be very efficient in keeping the pavement safe from deformation caused by moisture. At the same time, using sustainable filler materials proved to be an environmentally eco-friendly method.
Existence and uniqueness of solutions for the stochastic Volterra-Levin equation with variable delays
Authors: Jin Shoubo
Published: August 2022

The Picard iteration method is used to study the existence and uniqueness of solutions for the stochastic Volterra-Levin equation with variable delays. Several sufficient conditions are specified to ensure that the equation has a unique solution. First, the stochastic Volterra-Levin equation is transformed into an integral equation. Then, to obtain the solution of the integral equation, the successive approximation sequences are constructed, and the existence and uniqueness of solutions for the stochastic Volterra-Levin equation are derived by the convergence of the sequences. Finally, two examples are given to demonstrate the validity of the theoretical results.
Aufnahme, Verbleib und Beendigung einer sozialtherapeutischen Behandlung: Eine Vollerhebung der sozialtherapeutischen Einrichtungen in Deutschland

Sozialtherapeutische Einrichtungen des Justizvollzugs (SothEn) dienen der Behandlung von (Sexual‐ und Gewalt-)Straftätern, um deren Rückfallrisiko nachhaltig zu reduzieren. Die vorliegende Studie erfasste unterschiedliche Merkmale zur Aufnahme, Verbleib und Beendigung einer sozialtherapeutischen Behandlung in allenN= 71 SothEn in Deutschland. Dabei wurde vor allem auf die Entscheidungsfindung in der Praxis wert gelegt. Aufnahmen erfolgten im gleichen Maße nach aktuell geltenden gesetzlichen Regelungen für Sexual- und Gewaltstraftäter sowie durch Einzelfallentscheidungen. Eine Diagnostik der Gefangenen bei der Aufnahme war die Regel und erfolgte meist in der eigenen Einrichtung. Darüber hinaus fanden in drei Viertel der Einrichtungen Probephasen zur Aufnahme statt, die vorab vereinbart wurden, eine festgelegte Dauer hatten und Interventionen zur Förderung der Motivation enthielten. In der Regel fanden Behandlungsabbrüche meist in den ersten 12 Monaten statt, häufig aufgrund mangelnder Motivation seitens der Gefangenen. Eine Nachbetreuung in Form von Bewährung oder Führungsaufsicht war im Großteil der Fälle gegeben. Obwohl Probephasen mit Motivationsmaßnahmen bei der Aufnahme in die SothEn vorhanden waren, war die Zahl der Abbrüche aufgrund unzureichender Behandlungsmotivation unverändert hoch, weshalb insbesondere die Motivationsförderung der Hochrisikoklientel weiterhin im Mittelpunkt zukünftiger Bemühungen stehen sollte.

CRISPR-Cas systems (clustered regularly interspaced short palindromic repeats) have shown great potential as efficient gene editing tools in disease therapeutics. Although numerous CRISPR-Cas systems have been developed, detailed mechanisms of target recognition and DNA cleavage are still unclear. In this work, we dynamically observe the entire process of conjugation, target recognition and DNA cleavage by single particle spectroscopy of CRISPR-Cas systems on single particle surfaces (gold) with the unique advantage of extended time periods. We show the CRISPR-Cas system, comprised of Cas endonuclease and single guide RNA, is stable and functional on single particle surfaces. Owing to the photostability of single particle surfaces, we directly observe in real time the entire dynamic process of conjugation, target recognition and DNA cleavage without photobleaching. We find heterogeneity in target recognition and DNA cleavage processes in which individual spectra vary significantly from one another as well as from the ensemble. We believe an in depth understanding of heterogeneities in CRISPR-Cas systems can overcome potential barriers in precision medicine and personalized disease therapeutics.
