Technical Report - Methods: Automated Discovery of Functional Relationships in Earth Systems Data
Authors: Reinecke Robert , Pianosi Francesca , Wagener Thorsten
Published: October 2023

Functional relationships capture how variables co-vary across specific
spatial or temporaldomains. However, these relationships often take complex forms beyond
linear, and they mayonly hold for sub-sets of the domain. More problematically, it is often
a priori unknown howsuch sub-domains are defined. Here we present a new method called SONAR
(diScovery OffuNctionaAl Relationships) that enables the automated discovery of
functional relationships inlarge datasets. SONAR operates on existing unstructured data and is
designed to be anexplorative tool for large datasets where manual search for functional
relationships would beimpossible. We test the method on groundwater recharge outputs of
several global hydrologicalmodels to explore its usefulness and limitations. Further, we compare
SONAR to the establishedCART (Classification and Regression Trees) and CIT (Conditional
Inference Trees) methods.SONAR results in smaller trees with functional relationships in the leaf
nodes instead of specificclasses or numbers. SONAR provides a robust and automated method for the
exploration offunctional relationships.

Published: October 2023

The practice of waqf (or Islamic endowment) has been recognized as the mainstream social development in Muslim society today since waqf greatly contributes to Malaysia's socio-economic development. Despite the fact that the current development of waqf is not fully utilized, waqf institutions must play a pivotal role in ensuring the attainment of waqf objectives in contemporary society. To achieve their strategic goals and fulfil their accountability towards relevant stakeholders and the public at large, a comprehensive measurement tool is required to assess the performance of waqf institutions holistically. Thus, the objective of this study is to explore the possible key performance indicators for waqf institutions in Malaysia using the balanced scorecard model with four main perspectives: financial perspective, stakeholder perspective, internal process perspective, and learning and growth perspective. The method of this study is based on a review of the literature on relevant performance measurement for waqf institutions in Malaysia. The findings of this study could assist waqf institutions in Malaysia to define their vision and strategy, as well as change their vision and strategy into specific activities, by implementing the proposed indicators that are measurable and comprehensive and are useful for waqf managers to make an accurate and informed decision. The outcome of this study could provide a guideline for designing a holistic and proper measurement system that can be implemented by all waqf institutions in Malaysia to maintain their sustainability and competitiveness.

Authors: Mladenovic Miodrag , Freezer Simon , Dreyer Craig , Meade Maurice J.
Published: October 2023

Objectives

To compare the pre- and postorthodontic treatment volumetric changes of the oral cavity proper (OCP) in extraction and nonextraction patients and to identify influencing variables.

Materials and Methods

Pre- and posttreatment cone-beam computed tomography (CBCT) scans of patients undergoing orthodontic treatment with fixed labial appliances and who satisfied the inclusion criteria were individually landmarked. Linear, angular, and volumetric measurements were determined. Descriptive statistics, repeated measure analyses of variance, correlations, and stepwise regression statistical analyses were applied.

Results

The CBCT scans of 54 patients who underwent the extraction of second premolars and/or extraction of second primary molars associated with agenic second premolars, and 59 nonextraction patients matched for crowding, were assessed. The mean age for both groups was 15 years. There was a statistically significant increase in the volume of the OCP for both the extraction and nonextraction groups, with the nonextraction group demonstrating a larger increase in the volume of the OCP. Gender, age, changes in mandibular and maxillary arch length, and changes in mandibular and maxillary intermolar width all influenced the change in the OCP volume.

Conclusions

The volume of the OCP increased in growing patients with and without the extraction of the second premolars and/or extraction of second primary molars associated with agenic second premolars. Patients who did not have extractions as part of their orthodontic treatment demonstrated a greater overall increase in OCP volume.

The authors trialed a mobile application, DiabetesXcel, which included type 2 diabetes–focused educational videos and modules, in 50 adults of Bronx, NY, a region with a high prevalence of diabetes and diabetes complications. From baseline to 4 months and from baseline to 6 months, there was significantly improved quality of life, self-management, knowledge, self-efficacy, depression, A1C, and LDL cholesterol among those who used DiabetesXcel. There was also a significant decrease in diabetes-related emergency department visits and hospital admissions from baseline to 6 months. This study demonstrates that DiabetesXcel could be beneficial for type 2 diabetes management.
Dissecting the Roles of the Nuclear and Mitochondrial Genomes in a Mouse Model of Autoimmune Diabetes
Authors: Zou Weiwei , Chezhian Janaki , Yu Tenghui , Liu Wensheng , Vu Jimmy , Slone Jesse , Huang Taosheng
Published: October 2023

Mitochondria, the organelles responsible for generating ATP in eukaryotic cells, have been previously implicated as a contributor to diabetes. However, mitochondrial proteins are encoded by both nuclear DNA (nDNA) and mtDNA. In order to better understand the relative contribution of each of these genomes to diabetes, a chimeric mitochondrial–nuclear exchange (MNX) mouse was created via pronuclear transfer carrying nDNA from a strain susceptible to type 1 diabetes (NOD/ShiLtJ) and mtDNA from nondiabetic C57BL/6J mice. Inheritance of the resulting heteroplasmic mtDNA mixture was then tracked across multiple generations, showing that offspring heteroplasmy generally followed that of the mother, with occasional large shifts consistent with an mtDNA bottleneck in the germ line. In addition, survival and incidence of diabetes in MNX mice were tracked and compared with those in unaltered NOD/ShiLtJ control mice. The results indicated improved survival and a delay in diabetes onset in the MNX mice, demonstrating that mtDNA has a critical influence on disease phenotype. Finally, enzyme activity assays showed that the NOD/ShiLtJ mice had significant hyperactivity of complex I of the electron transport chain relative to MNX mice, suggesting that a particular mtDNA variant (m.9461T>C) may be responsible for disease causation in the original NOD/ShiLtJ strain.

Article Highlights

Mitochondria have been previously implicated in diabetes, but the specific genetic factors remain unclear. To better understand the contributions of mitochondrial genes in nuclear DNA (nDNA) versus mtDNA, we created mitochondrial–nuclear exchange (MNX) mice carrying nDNA from a diabetic strain and mtDNA from nondiabetic mice. Long-term tracking of MNX mice showed occasional large shifts in heteroplasmy consistent with an mtDNA bottleneck in the germ line. In addition, the MNX mice showed improved survival and delayed incidence of diabetes relative to the unaltered diabetic mice, which appeared to be linked to the activity of respiratory complex I.

Mathematics is the clearest and most unambiguous science. However, mathematics for most students, mathematics is one of the most feared and difficult subjects to understand due to a lack of understanding of the concepts needed. In line with the mathematical concepts needed in learning, a teacher can associate mathematical concepts with local culture. Mathematics found in culture is called ethnomathematics. This study explores the mathematical concepts of Gotong and Bulang. Gotong and Bulang are part of the Simalungun traditional clothing which functions as a head cover for married men and women. This study aims to explore various mathematical concepts contained in Gotong and Bulang Simalungun. The research method used is a qualitative method with an ethnographic approach. Data collection was carried out through observation, interviews, documentation, and literature study. The data collection instruments used were observation sheets, interview sheets, cameras, field notes and voice recorders. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results obtained from this study indicate that there are mathematical concepts in Gotong and Bulang, namely the concept of numbers, parallel lines, folding symmetry, triangular plane shapes, and transformation geometry. Thus, it can be concluded that Gotong and Bulang Simalungun can be used as tools for learning mathematics that are concrete in understanding mathematical concepts.

Inhibitory control exhibits a significant correlation with overall cognitive abilities. Past research largely measured disinhibition using experimental protocols, predominantly featuring healthy or youthful participants, or caregiver-supplied information, potentially neglecting an objective assessment of pronounced disinhibition within a naturalistic context. We posit that the observation of prominent disinhibition behaviors across various cognitive assessment tasks provides an objective measurement of innate disinhibition, bypassing the need for participant awareness or concentrated effort toward inhibition. The present study, designed as a secondary analysis of prior research, aims to explore the relationship between cognitive functions and observed disinhibition behavior during cognitive testing in patients exhibiting cognitive impairment symptoms. A retrospective analysis was performed on the records of 224 patients' cognitive tests, including recorded disinhibition behavior, without employing any exclusion criteria. Findings revealed that patients demonstrating at least one instance of disinhibition during testing presented significantly lower overall cognitive functions, excluding long-term memory, than their counterparts without disinhibition. Notably, multiple regression analysis identified comprehension and conceptualization abilities as significant predictors of disinhibition severity. These findings, aligning with earlier research, serve to strengthen the credibility of previous studies on this topic.

Published: October 2023

This study was aimed to determine the characteristics of the soils of perennial ryegrass genotypes found in the natural flora in the Central Anadolu Region in Türkiye. Within the scope of the study, perennial ryegrass populations were collected from the provinces of Ankara, Eskişehir, Afyon, Konya, Aksaray, Karaman and Mersin and Antalya provinces in 2006 and 2007. Plants were collected and soil samples were taken and analysed from 87 sites in Ankara (20), Eskişehir (9), Afyon (5), Konya (39), Aksaray (1), Karaman (5), Mersin (2) and Antalya (6). According to the analysis results, the pH varied between 6.35-8.50, EC 52-1395 µS/cm, organic matter 0.04-9.1 %, lime 1.2-64.2%, P2O5 4.28-128.7 mg/kg, K2O 24.7-1360. 8 mg/kg, Ca 820-4030 mg/kg, Mg 32.7-3569 mg/kg, Na 0.6-2016 mg/kg, Fe 2.78-67.50 mg/kg, Zn 0.10-8.97 mg/kg, Cu 0.21-9.43 and Mn 2.33-42.34 mg/kg. As a result of soil analyses, large differences were observed between the locations where plants were collected in terms of the characteristics examined. This change shows the potential of developing grass varieties that can grow in different soil properties with a good breeding study of perennial ryegrass populations.
The Effect of Differential Pressure and Permanent Pressure Loss on Multi-Hole Orifice Plate
Authors: Hariguru TM , Srinivasan S
Published: October 2023

The widely used orifice plate falls under restricted type flow devices, has the highest differential pressure and permanent pressure drop in the ensemble. The objective is to curtail the permanent pressure drop and maintain the differential pressure across the orifice plate, and thereby, the power required to pump the liquid is retrenched. So, three-hole, four-hole and five-hole orifice plates with an identical area to that of the single-hole orifice plate were designed and experiments were carried out. It is observed that the experimental results almost matched with the simulation data. In comparing the performance, the four-hole orifice plate yielded a higher differential pressure and higher-pressure loss. In contrast, the five-hole orifice yielded lower differential pressure and higher-pressure loss compared to the single-hole orifice plate. In case of three-hole orifice plate it performed better than the single-hole orifice with reduced pressure loss and higher differential pressure. It was also found that the power consumed by the pump for pumping was lower for three-hole, four-hole and five-hole orifice plates compared to the single-hole orifice plate. Thus, the three-hole orifice plate performs better than a single-hole orifice plate in terms of higher differential pressure, reduced permanent pressure loss and lower power consumption of the pump.

Sarcoidosis is a chronic systemic granulomatous disease that can show overlapping clinical features with various rheumatological entities. Even though it can be more commonly associated with Sjögren syndrome and systemic lupus erythematosus, only on rare occasions, it can concomitantly occur with rheumatoid arthritis. While lacking a gold standard diagnostic tool, sarcoidosis remains an exclusion diagnosis. Moreover, an atypical presentation of a rare disease on the background of another systemic disease can be challenging, even for an experienced physician. We present a rare case of a patient with a long-standing history of rheumatoid arthritis treated with methotrexate who developed sarcoidosis with an unusual presentation and possible cardiac involvement.

Authors: Coteț Marius-Alexandru , Belaconi Ionela Nicoleta , Ruseva Inna Dencheva , Toma Claudia Lucia
Published: October 2023

We describe a series of five cases of sporadic lymphangioleiomyomatosis (LAM) diagnosed in a 2-year period and followed for at least 6 months. All cases describe women aged between 37 years and 67 years (median at 44), mostly non-smokers, either with symptomatic presentations, complications at debut or incidental imagistic diagnosis. The cystic lesions were unanimous, but two cases had atypical patterns. Spirometric parameters were normal in two cases, the rest presenting obstruction with hyperinflation ± bronchodilator positive response. The diffusing capacity of lung for carbon monoxide (DLCO) varied between 79.8% and 29.5%. Two cases had histopathological confirmation, one of which was really unexpected considering its imagistic pattern. The therapeutic intervention consisted of sirolimus and/or bronchodilator. The evolution was stationary for four cases and unfavourable for one. This case series ranges from textbook to atypical LAM and has the aim to raise awareness regarding this rare disease.

Abstract

Tilapia fish filet is one of the protein-rich foods needed by the body. The freshness quality of the tilapia fish filet is affected by the quality of the raw materials and the method of killing the fish. This study aimed to determine the effect of the lethal technique and the length of post-mortem time on the freshness of tilapia fish (Oreochromis mossambicus) filets. This study used a factorial-CRD trial (Completely Randomized Design) for two factors. The first factor is how to kill the fish (floating death, cold temperature, and ikejime technique). The second factor was the length of post-mortem time (0, 2, 4, 6, 8, 10, 12, and 14 hours). Each treatment was repeated by 2 times so that 48 samples were obtained from 24 treatment combinations. The observed parameters are the rigor index, organoleptic freshness, pH, and protein content. Observational data were processed by Analysis of Variance (ANOVA), Duncan test, and Kruskal-Wallis test. The results of this study indicate that the method of shutting down and the length of time post-mortem significantly affect several parameters of the freshness quality of tilapia fish fillets. The best combination of treatment is lethal with the ikejime technique with a post-mortem time of 0 hours which has a pH of 6.94, protein content of 26.65% and fish meat organoleptic score of 8.80, and fish meat texture score of 8.95.

Abstract

Cow urine has the potential to become biourin. This study aims to determine the effect of the type of diffuser on the quality of biourin, as well as to determine the best type of diffuser during the fermentation process. This study used a completely randomized design consisting of 5 treatments and 3 replications. Each treatment contained 10 liters of urine, 2% nitrifying bacteria, and 2% molasses. The treatment was carried out without aeration, treatment using aeration without a diffuser, treatment using a fine bubble diffuser, treatment using a coarse bubble diffuser, and treatment using an aerated stone diffuser. This fermentation was carried out for 20 days with measurements every 5 days. Parameters observed were temperature, pH, TDS, EC, C-Organic, N-Total, and C/N Ratio during the fermentation process. The results of the study showed that the use of several types of diffusers had a significant effect on the process of fermenting cow urine. The fermentation process without using a diffuser showed that as the fermentation time increased, the pH value decreased from 7.72 to 7.54. On the 20th day of bio-urine fermentation, the highest Biochemical Oxygen Demand value was shown by the treatment using a fine bubble diffuser with a value of 9.2 mg/l. Of the five urine fermentation treatments, only fermentation with a diffuser met standard No.70/Permentan/SR.140/10/2011. Treatment with a type of fine bubble diffuser is the best treatment.

Abstract

The Management Performance Ratio (MPR) is a comparison between the water flowrate given and the water flowrate requirement for each agricultural land. The subak system in Bali is based on socio-technical-religious and economic concepts. This study aims to calculate the MPR value and its distribution as well as find out the irrigation water distribution strategy so that irrigation performance becomes "adequate" to "good" in Subak Gede Kedewatan, Gianyar Regency. This research was carried out using a quantitative analysis approach through surveys and direct measurements in the field. The result showed that percentage distribution of MPR criteria for "good" was 5 subaks (18.52%), "adequate" 4 subaks (14.81%), "poor" 9 subaks (33.33%), and "very poor" 9 subaks (33 ,33%). The MPR value of subak in the upstream area is entirely in the "very poor" criterion with an MPR value of 1.85. Followed by subak in the central region, all of them are in the "low" criterion with an MPR value of 1.45. In contrast to the downstream, the subaks in this area have the criteria of "adequate" and "good" with a distribution of RPM values ??of 0.64 - 1.05. Subaks that get excess water, then the rest of the irrigation water is channeled to the pangkung, which will be the main water source for subak natak tiyis (tapping taps).

This paper aims at presenting the findings of a study examining the deployment of discourse markers (DMs) in IELTS essays by EFL learners in terms of beliefs and practices. The study involved a group of 60 EFL learners who were taking IELTS preparation courses at an English language center in Ho Chi Minh City, Vietnam. The research data were gained from questionnaires and 120 IELTS essays (Task 2) written by EFL learners. The questionnaire data were processed using the SPSS software, while the essay data were scrutinized by AntConc software. The findings showed that EFL learners strongly believed in the importance of DMs in writing, and they deployed DMs in their writing at a moderate frequency. Additionally, among six categories of DMs, EFL learners utilized elaborative markers more than other categories of DMs. This paper also presents some pedagogical implications in an attempt to improve the quality of English language teaching and learning in general and English writing teaching and learning in specific at the research context and other similar EFL ones.
An effective artificial feeder for breeding Aedes aegypti (Diptera: Culicidae)
Authors: BONICA Melisa B , MARTI Gerardo A , MICIELI Maria V
Published: October 2023

Mosquitoes, like other hematophagous insects, need to feed on blood to produce eggs. For laboratory colony maintenance, live animals are generally used, while various artificial feeders with different characteristics have been developed for experimental assays. In this study, a previously developed and pathogen-tested glass artificial feeder was selected and evaluated for rearing Aedes aegypti (Linnaeus). The device utilizes bovine gut as a membrane and human blood as a food source, maintaining a constant temperature of 37 °C through a thermostatic bath that enables water circulation around the feeder. Egg hatching, feeding rates, and fertility were analyzed for three cohorts of a parental lineage (P) and their respective filial lineages (F1) over a period of 4-5 weeks. The results demonstrated the efficacy of this methodology for rearing an Ae. aegypti colony up to the second generation, with average egg hatching rates of P= 0.92 and F1= 0.80, average feeding rates of P= 0.54 and F1= 0.73, and egg quantities obtained of P= 1809 and F1 = 8579.

Dolichothrips indicus (Hood, 1919) (Thysanoptera: Phlaeothripidae) is frequently found in flower buds, flowers and inflorescences of different plant species, so its role as a possible pollinating agent is considered in several studies. The presence of D. indicus in panicles of the “Azúcar” variety mango crop is recorded for the first time in Colombia. The diagnostic morphological characteristics of the species are described and illustrated.

An Embodied Feminist Poethics of Improper Speech in Atwood’s Alias Grace and Christiansë’s Unconfessed
Authors: Ellis Jeanne
Published: October 2023

In this paper, I argue that the cross-fertilising entanglements of narrative/literature, theory, and embodiment that constitute Margaret E. Toye’s concept of “narrative as embodied theory” in “Towards a Poethics of Love: Poststructuralist Feminist Ethics and Literary Creation” are especially appropriate to revisionary historical fiction written by women in which silenced histories of trauma are recovered and given voice. I refer to examples from Margaret Atwood’s Alias Grace (1998) and Yvette Christiansë’s Unconfessed (2006) as illustrations of what I term “an embodied feminist poethics of improper speech,” a theoretical and methodological reconfiguration of Toye’s terms.

Authors: Selebi Olebogeng , Landsberg Karen , Makaya Mamosa
Published: October 2023

South Africa faces several socioeconomic issues—gender inequality being one of them. This issue cannot be addressed by government alone and requires the involvement of other stakeholders. This study provides valuable insights into existing multi-stakeholder partnerships (MSPs) in South Africa aimed at achieving Sustainable Development Goal (SDG) 5.5 (gender equality through support for women in leadership). The aim of this qualitative research study was threefold. Firstly, it investigated the focus areas of existing strategic MSPs driving the achievement of SDG 5.5. Secondly, it aimed to understand the collaborative approaches within these partnerships. Finally, it determined how existing relationships could be improved. This was a generic qualitative study. Twelve professionals (from 12 organisations) participated in the semi-structured interviews. The findings were analysed using thematic analysis. Several findings came to the fore—one of which related to the involvement of men as a key driver of gender equality in South Africa.

Published: October 2023

Background: Thyroid nodules are a prevalent worldwide disease with complex pathological types. They can be classified as either benign or malignant. This paper presents a tool for automatically classifying histological images of thyroid nodules, with a focus on papillary carcinoma and follicular adenoma. Methods: In this work, two pre-trained Convolutional Neural Network (CNN) architectures, VGG16 and VGG19, are used to extract deep features. Then, a principal component analysis was used to reduce the dimensionality of the vectors. Then, three machine learning algorithms (Support Vector Machine, K-Nearest Neighbor, and Random Forest) were used for classification. These investigations were applied to our database collection, Results: The proposed investigations have been applied to our private database collection with a total of 112 histological images. The highest results were obtained by the VGG16 transfer deep feature and the SVM classifier with an accuracy rate equal to 100%.

Published: October 2023

Background: Emotions come in all shapes and forms. Some of them can be external, visible, and clearly comprehensible, while others can seemingly be coming out of thin air. Knowing what causes an emotion is crucial for better therapy and mental health. Therefore, in this manuscript, we address the problem of emotions causality. Methods: We propose a comparison of three traditional clustering models: Gaussian mixture model, HDBSCAN, and fuzzy c-means, to categorize each emotion described in the DEAP database. It contains over 1700 points, and has no prior label as to which type of stressor the subject’s emotion is generated from. This labelling task has been conducted by a psychiatrist. Results: The fuzzy c-means yields the highest results, with an accuracy of 57.13%, followed by the Gaussian mixture model at 39.49% and the HDBSCAN method with only 18.86%. Another score computed is the mutual information score which shows how homogenous the clusters are for each model. Conclusion: The data from DEAP is very heterogeneous and its density is stable, which may indicate that classification would be the better option, in terms of accuracy and homogeneity of the clusters.
Distinct aggregation and toxicity of N-terminally truncated Abeta4-42 over Abeta1-42 in the presence of Zn(II)

Published: October 2023

In the brains of Alzheimer’s disease (AD) patients, the accumulation of amyloid-beta (Abeta) aggregates is found. A peptides can be truncated at the Phe4 residue in the N-terminus forming Abeta4-x peptides, which is a predominant modification observed in AD-affected brains. This modification alters Abeta’s metal-binding, aggregation, and toxicity properties. Here we report the distinct aggregation and toxicity of an N-terminally truncated Abeta, Abeta4-42, in the presence of Zn(II) with and without Abeta seeds, compared to those of full-length Abeta1-42. Our studies demonstrate that such difference between Abeta4-42 and Abeta1-42 in the presence of Zn(II) is directed by their different Zn(II)-binding properties.

Published: October 2023

Prussian Blue, a blue coordination polymer, emerges as a promising candidate in the realm of biomedicine. Its nanoparticles, known as catalytic labels or nanozymes, exhibit remarkable peroxidase-like properties and serve as effective antioxidants. Unsurprisingly, the demand for synthesizing Prussian Blue nanoparticles with customizable sizes is on the rise. In this study, we unveil a novel approach to synthesizing Prussian Blue nanoparticles. In this work, the synthesis of Prussian Blue nanoparticles by reducing an equimolar mixture of FeCl3 and K3[Fe(CN)6] with hydrogen peroxide in different water-alcohol mixtures was demonstrated for the first time. Alcohols with a lower dielectric constant (propanol-1, isopropyl alcohol, and tert-butanol) contribute to an increase in nanoparticle size, particularly at mole fractions of 0.02-0.05 and beyond. Conversely, alcohols with a higher dielectric constant (ethanol, methanol, ethylene glycol, and propylene glycol, excluding glycerol) demonstrate the ability to decrease nanoparticle size at mole fractions of 0.2-0.26 and higher. Building upon these findings, we present a scalable and reproducible method for preparing small Prussian Blue nanoparticles, measuring 30-40 nm, with enhanced peroxidase-like activity using 79.2% ethylene glycol as a solvent. The proposed mechanism behind the effect of ethylene glycol involves the limitation of both growth and secondary aggregation of Prussian Blue nanoparticles. These synthesized nanoparticles prove their efficiency as catalytic labels in a model vertical flow immunoassay designed to detect antibodies against SARS-CoV-2.
15NRORC: An Azine Labeling Protocol
Authors: Tolchin Zachary , Smith Joel
Published: October 2023

A practical method for the synthesis of 15N-labeled azines with a high degree of isotopic enrichment is described. Activation of azine heterocycles with an electron-deficient arene allows for the facile substitution of the nitrogen atom with a specifically designed 15N-labeled reagent that undergoes a canonical ANRORC-type mechanism. A wide range of azines can be converted to their corresponding 15N isotopologs using this method, and it also allows for dearomative access to reduced heterocyclic congeners. A short dearomative formal synthesis of 15N-solifenacin is accomplished as well to demonstrate a practical appli-cation of this method for generating labeled pharmaceuticals.

Published: October 2023

Transition metal-catalyzed asymmetric nitrene transfer is a powerful method for the generation of enantioenriched amines frequently found in natural products and bioactive molecules. We report herein a highly chemo- and enantioselective intramolecular silver-catalysed aziridination that uses 2,2,2-trichloroethoxysulfonyl (Tces)-protected carbamimidates as an underexplored class of nitrene precursors. Several homoallylic carbamimidates containing di- and trisubstituted olefins were converted into [4.1.0]-bicyclic aziridines in good-to-excellent yields (up to 98%) and enantioselectivities (up to 99% ee). Computational insights shed insight into the reasons carbamimidates prove superior to the sulfamate and carbamate nitrene precursors that are traditionally used in this chemistry. Post-synthetic modifications afford difunctionalized amines bearing two contiguous, enantioenriched chiral centres.
