Revitalizing Vygotskian radical legacy in cultural-historical research for addressing racial injustice in education
Authors: Pollock Rebekah , Ko Dosun
Published: September 2024

This study responds to recent calls for the revitalization of the Vygotskian radical legacy and the reclamation of critical uses of cultural-historical research through a retrospective analysis of two case studies. The first case study describes the development and application of a discourse-based formative intervention framework to reveal psychological processes associated with reimagining and enacting possible futures among early adolescent Black girls. The second presents the FutureMaking Learning Lab’s efforts to address racial injustice in school discipline and empower parents and school personnel to collectively envision a culturally responsive, inclusive school system. Importantly, these case studies represented epistemological, methodological, and axiological expansions of formative intervention methodology through efforts to amplify the voices of participants and leverage their experiential knowledge through interactive participation structures and researchers’ integration of critical theoretical lenses to devise and employ mediating artifacts. These, in turn, support participants’ transformative agency to criticize current practices, ideologies, and structures, and imagine possible futures
Pullulan-DOX/PVA-PDMS Biopolymeric Core-Shell Nanofibers Potential for Drug Delivery Systems
Authors: Tören Elçin , Mazari Adnan Ahmed
Published: September 2024

In this research, a novel drug delivery system shell was created by loading doxorubicin hydrochloride (DOX) into Pullulan and integrating the core into a polyvinyl alcohol (PVA) and Polydimethoxysilane (PDMS) composite matrix. The incorporation of DOX into the pullulan solution was carried out to take advantage of Pullulan's biocompatibility, biodegradability and hydrophilic nature. The hydrophilic nature of PVA can result in rapid drug release, while the hydrophobic nature of PDMS allows for slower drug release. The use of PVA-PDMS polymers together in the shell offers an initial rapid release followed by a prolonged and controlled drug release. This combination is superior to PVA or PDMS in terms of safety, mechanical strength, flexibility, controlled drug release and structural stability. This innovative composite system was designed to optimise DOX's controlled release to increase its therapeutic efficacy and reduce systemic toxicity. The kinetics of the drug release was characterised by an initial burst release followed by a sustained release phase, allowing controlled and prolonged release of the chemotherapeutic agent. Our results indicate that the pullulan/PVA-PDMS composite is a promising candidate for practical drug delivery applications, especially in cancer therapy.
dentification of novel potential anti-quorum sensing molecules against LasR of Pseudomonas aeruginosa using in silico approach
Authors: Kumar Vivek , Srivastava Anmol , Sharma Deepmala , Agarwal Vishnu
Published: September 2024

Quorum sensing (QS), commonly known as inter-and intracellular communication in bacteria, is accomplished by small, diffusible signaling molecules termed as autoinducers. Numerous virulence factors that are involved in pathogenesis are regulated by QS. It has come to attention as a result of the growing resistance of bacteria to conventional antibiotics, as it applies less to no selective pressure to limit the development of resistance among bacteria. For inhibitors, LasR, a transcription factor that regulates QS in Pseudomonas aeruginosa, is a promising therapeutic target. Hence, the objective of this study is to identify possible LasR inhibitors from natural substances. Virtually 2068 ZINC database compounds were tested against the LasR structure. Following the filtering of suitable compounds using Lipinski's rule and ADME criteria. Depending on binding energy, eight novel potential QS inhibitory agents were identified. To determine how inhibitors and targets bind, structures of LasR-ligand complexes were examined. It is important to note that all of the compounds are structurally distinct from 3-oxo-C12-HSL, a native autoinducer of LasR, which is essential for the activation of LasR dimer that regulates QS system in Pseudomonas aeruginosa. These inhibitors are natural in origin and hence can be very useful in treating Pseudomonas infection; however, we have to properly evaluate their effectiveness, safety, and mode of action, through in vivo and in vitro investigation.

Fibro-adipogenic progenitors (FAPs) are muscle-resident mesenchymal progenitors that can contribute to muscle tissue homeostasis and regeneration, as well as postnatal maturation and lifelong maintenance of the neuromuscular system. Recently, traumatic injury to the peripheral nerve was shown to activate FAPs, suggesting that FAPs can respond to nerve injury. However, questions of how FAPs can sense the anatomically distant peripheral nerve injury and whether FAPs can directly contribute to nerve regeneration remained unanswered. Here, utilizing single-cell transcriptomics and mouse models, we discovered that a subset of FAPs expressing GDNF receptors Ret and Gfra1 can respond to peripheral nerve injury by sensing GDNF secreted by Schwann cells. Upon GDNF sensing, this subset becomes activated and expresses Bdnf. FAP-specific inactivation of Bdnf (Prrx1Cre; Bdnffl/fl) resulted in delayed nerve regeneration owing to defective remyelination, indicating that GDNF-sensing FAPs play an important role in the remyelination process during peripheral nerve regeneration. In aged mice, significantly reduced Bdnf expression in FAPs was observed upon nerve injury, suggesting the clinical relevance of FAP-derived BDNF in the age-related delays in nerve regeneration. Collectively, our study revealed the previously unidentified role of FAPs in peripheral nerve regeneration, and the molecular mechanism behind FAPs’ response to peripheral nerve injury.

Authors: Li Qiong , Xu Zhichao , Gong Qianhui , Shen Xiaobing
Published: September 2024

Background

The fatal risk of high-altitude pulmonary edema (HAPE) is attributed to the inaccurate diagnosis and delayed treatment. This study aimed to identify the clinical characteristics and to establish an effective diagnostic nomogram for HAPE in habitual low altitude dwellers.

Methods

A total of 1,255 individuals of Han Chinese were included in the study on the Qinghai-Tibet Plateau at altitudes exceeding 3,000 m. LASSO algorithms were utilized to identify significant predictors based on Akaike’s information criterion (AIC), and a diagnostic nomogram was developed through multivariable logistic regression analysis. Internal validation was conducted through bootstrap resampling. Model performance was evaluated using ROC curves and the Hosmer-Lemeshow test.

Results

The nomogram included eleven predictive factors and demonstrated high discrimination with an AUC of 0.787 (95% CI [0.757–0.817]) and 0.833 (95% CI [0.793–0.874]) in the training and validation cohorts, respectively. Calibration curves were assessed in both the training (P = 0.793) and validation datasets (P = 0.629). Confusion matrices revealed accuracies of 70.95% and 74.17% for the training and validation groups. Furthermore, decision curve analysis supported the use of the nomogram for patients with HAPE.

Conclusion

We propose clinical features and column charts based on hematological parameters and demographic variables, which can be conveniently used for the diagnosis of HAPE. In high-altitude areas with limited emergency environments, a diagnostic model can provide fast and reliable diagnostic support for medical staff, helping them make better treatment decisions.

Published: September 2024

The yield and concentration of secondary metabolites (SMs) in plants can vary due to numerous challenges such as dynamic environmental conditions, moisture, soil quality, soil organic matter and plant genetics. To obtain a good yield of SMs novel elicitation approaches, such as the use of biotic and abiotic stressors, genetic modifications, and optimized growth conditions, have been practiced, particularly the use of selenium nanoparticles (SeNPs) and light emitting diode (LED) interaction through employing tissue culture technique. In the present study, in vitro callus cultures of sandalwood (Santalum album L.) were subjected to elicitation with different concentrations of SeNPs with doses of 30 µg/L, 60 µg/L, and 90 µg/L in combination with green (∼550 nm), red (∼660 nm) and blue (∼460 nm) LED lights. Interaction of these treatments produced 16 treatments replicated three times in 48 test tubes. The results were analysed using two-way ANOVA and Tukey’s HSD test. The study revealed that synergistic interaction between SeNPs and LED light wavelengths significantly enhanced callus growth and secondary metabolite (SM) production eliciting callus cultures with blue LED light and a dose of 90 µg/L SeNPs resulted in an increase in callus growth including fresh weight, dry weight, and the number of shoot branches per callus. This combined treatment positively influenced the functions of major bioactive antioxidants such as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and phenylalanine ammonia-lyase (PAL). Furthermore, the concentrations of essential secondary metabolites, including total phenolic, total saponins, casein/BSA/PVPP-bound tannins, flavan-3-ols, and tocopherols experienced substantial elevation under the synergistic influence of SeNPs and LED light conditions. The sandalwood plants produced through the callus culturing technique using optimized SeNPs and LED lights show an enhanced yield of secondary metabolites, which will be very useful and potential for pharmaceutical, cosmetic and various other industries to discover and develop novel products.

Background

Tennis requires movement abilities in changing playing situations. This article investigates the relationship between lower extremity strength asymmetry ratio and linear and multidimensional running performances in female tennis players.

Methods

A total of 56 female tennis players, with a mean age of 15.44 ± 0.50 years, participated in the study—the research design involved three sessions at 48-hour intervals. In the first session, athletes performed dominant and non-dominant countermovement jump (CMJ) and board jump (BJ) tests. The second (sec) session included 10-meter (−m) and 30-m linear running performance tests, while the final session assessed multidimensional running performance with a change of direction (COD) test. The relationship between CMJ and BJ asymmetry ratios and linear and multidimensional running performances was analysed using the Pearson correlation coefficient. Bilateral asymmetry rates in linear and multidimensional running performance were determined through linear regression analysis.

Results

The dominant CMJ recorded 17.56 ± 3.47 cm, while BJ was 130.23 ± 21.76 cm, and the non-dominant CMJ measured 16.79 ± 4.51 cm with a BJ of 147.52 ± 30.97 cm. The athletes had a CMJ asymmetry rate of 12.67 ± 11.29% and a BJ asymmetry rate of 7.19 ± 5.28%. A relationship was seen between the CMJ asymmetry rate and 30-m running performance (r = 0.368, p < 0.05). There was no correlation between BJ asymmetry rate and 10-m running performance. Significant correlations were found between 30-m (r = 0.364) and COD (r = 0.529) running performances (p < 0.05).

Conclusions

It can be said that the CMJ asymmetry ratio may negatively affect 30-m and the BJ asymmetry ratio may negatively affect 30-m and COD performance.
Central Angiotensin II type 1 receptor deficiency alleviates renal fibrosis by reducing sympathetic nerve discharge in nephrotoxic folic acid–induced chronic kidney disease
Authors: Wan Qijun , Yang Zhichen , Li Lingzhi , Wu Liling
Published: September 2024

Background

Fibrosis after nephrotoxic injury is common. Activation of the paraventricular nucleus (PVN) renin-angiotensin system (RAS) and sympathetic nervous system (SNS) are common mechanism of renal fibrosis. However, there have limited knowledge about which brain regions are most affected by Angiotensin II (Ang II) after nephrotoxic injury, what role does Angiotensin II type 1a receptors (AT1R) signaling play and how this affects the outcomes of the kidneys.

Methods

In nephrotoxic folic acid–induced chronic kidney disease (FA-CKD) mouse models, we have integrated retrograde tracer techniques with studies on AT1afl/fl mice to pinpoint an excessively active central pathway that connects the paraventricular nucleus (PVN) to the rostral ventrolateral medulla (RVLM). This pathway plays a pivotal role in determining the kidney’s fibrotic response following injury induced by folic acid.

Results

FA-CKD (vs sham) had increased in the kidney SNS activity and Ang II expression in the central PVN. The activation of Ang II in the PVN triggers the activation of the PVN-RVLM pathway, amplifies SNS output, thus facilitating fibrosis development in FA-CKD mouse. Blocking sympathetic traffic or deleting AT1a in the PVN alleviated renal fibrosis in FA-CKD mice.

Conclusions

The FA-CKD mice have increased the expression of Ang II in PVN, thereby activating AT1a-positive PVN neurons project to the RVLM, where SNS activity is engaged to initiate fibrotic processes. The Ang II in PVN may contribute to the development of kidney fibrosis after nephrotoxic folic acid-induced kidney injury.
Impact of community-based forest restoration on stand structural attributes, aboveground biomass and carbon stock compared to state-managed forests in tropical ecosystems of Sri Lanka
Authors: Ahmad Shahzad , Xu Haiping , Ekanayake E. M. B. P.
Published: September 2024

Estimation of plant community composition, aboveground biomass and carbon stock is crucial for understanding forest ecology, strengthening environmental management, and developing effective tools and policies for forest restoration. This study was conducted in nine different forest reserves in Sri Lanka from 2012 to 2018 to examine the impact of community-based forest restoration (CBFR) on stand structural attributes, aboveground biomass, and carbon stock compared to state-managed forests. In total, 180 plots (90 plots in community-managed restoration blocks (CMRBs) and 90 plots assigned to state-managed restoration blocks (SMRBs)) were sampled at the study site. To conduct an inventory of standing trees, circular plots with a radius of 12.6 m (equivalent to an area of 500 square meters) were established. The Shannon diversity index, Allometric equations and Difference in Differences (DID) estimation were used to assess the data. Our study provides evidence of the positive impact of the CBFR program on enriching trees diversity. Considering stand structural attributes of both blocks showed higher trees density in the smaller diameter at breast height (DBH) category, indicating growth in both CMRBs and SMRBs. The results showed that tree biomass and carbon density were disproportionally distributed across the nine different forest reserves. On average, tree biomass and carbon density were higher in SMRBs (79.97 Mg ha−1, 37.58 Mg C ha−1) compared to CMRBs (33.51 Mg ha−1, 15.74 Mg C ha−1). However, CMRBs in Madigala reserve represent the highest biomass (56.53 and 59.92 Mg ha−1) and carbon density (26.57 and 28.16 Mg C ha−1). The results of biomass and carbon estimates were higher in all SMRBs in the nine different forest reserves compared to CMRBs. The findings suggest that future forest restoration programs in Sri Lanka should enhance participatory approaches to optimize tree species diversity, density and carbon storage, particularly in community-controlled forests. Our findings could assist developing tropical nations in understanding how CBFR impacts forest restoration objectives and improves the provision of ecological services within forests.
Turbidivision: a machine vision application for estimating turbidity from underwater images
Authors: Rudy Ian M. , Wilson Matthew J.
Published: September 2024

The measurement of turbidity serves as a key indicator of water quality and purity, crucial for informing decisions related to industrial, ecological, and public health applications. As existing processes require both additional expenses and steps to be taken during data collection relative to photography, we seek to generate accurate estimations of turbidity from underwater images. Such a process could give new insight to historical image datasets and provide an alternative to measuring turbidity when lower accuracy is acceptable, such as in citizen science and education applications. We used a two-step approach to a machine vision model, creating an image classification model trained on image data and their corresponding turbidity values recorded from a turbidimeter that is then used to generate continuous values through multiple linear regression. To create a robust model, we collected data for model training from a combination of in situ field sites and lab mesocosms across suspended sediment and colorimetric profiles, with and without a Secchi disk for visual standard, and binned images into 11 classes 0–55 Formazin Nephelometric Units (FNU). Our resulting classification model is highly accurate with 100% of predictions within one class of the expected class, and 84% of predictions matching the expected class. Regression results provide a continuous value that is accurate to ±0.7 FNU of true values below 2.5 FNU and ±33% between 2.5 and 55 FNU; values that are less accurate than conventional turbidimeters but comparable to field-based test kits frequently used in classroom and citizen science applications. To make the model widely accessible, we have implemented it as a free and open-source user-friendly web, computer, and Google Play application that enables anyone with a modern device to make use of the tool, the model, or our repository of training images for data collection or future model development.
The Effect of Processing Methods on Quality Parameters of Jackfruit Seed Flour (JSF) from Different Cultivars
Authors: U. Sreejaya , U. Krishnaja
Published: September 2024

India has a large jackfruit farming industry; however, after the edible part is eaten, the nutrient-rich seeds are thrown away as waste. The study was aimed at investigating the functional properties and sensorial attributes of jackfruit seed flour from various treatments. The results revealed a significant difference between the functional characteristics and sensory attributes of jackfruit seed flour samples processed by soaking the seeds in various soaking media. Based on the results, two seed flour samples (VS1 - Varikka soaked in water and KS1 – Koozha soaked in water) were selected as the best and evaluated for their proximate composition. The cultivar Varikka had more crude fiber (2.96%), ash (2.61%), protein (13.17 g/100g) and carbohydrate content (76.82 g/100g). Both the seed flour samples had negligible amount of fat (VS1 – 1.72 and KS2 – 1.68%), less fat allows for the prevention of rancidity issues and longer shelf life of the product. This procedure makes it feasible to preserve jackfruit seeds by converting them into flour, extending their shelf life. Facts from nutritional, functional and sensory assessments suggest that jackfruit seed flour can be employed in various processed products. It can also be used as substitute for starch.

Published: September 2024

Strawberry is a globally cherished fruit, celebrated for their sweet flavor, vibrant color, and rich nutritional profile. The use of biofertilizers in strawberry cultivation is gaining importance in India due to their eco-friendly and sustainable nature. Biofertilizers enhance soil fertility by promoting beneficial microbial activity, which improves nutrient availability and uptake by strawberry plants. This leads to healthier crops with better yields and quality by reduced application of inorganic fertilisers. It ultimately benefits both the environment and farmers' long-term productivity. The experimental results revealed that T8 (RDF + Azotobacter @ 2g/plant + PSB @2g/plant + Azospirillum @2g/plant) significantly increased the plant height (16.82 cm), plant spread (32.78 cm), fruit length (45.88 mm), breadth (38.96 mm), weight (12.76 g), TSS (9.42 °Brix), anthocyanin content (26.14 mg/100g) and yield attributes i.e., yield plant-1 (238.88 g) and yield hectare-1 (13.14 t/ha). It also found that the plants treated with T8 (RDF + Azotobacter @2g/plant + PSB @2g/plant + Azospirillum @2g/plant) had maximum leaf nutritional content, namely -  nitrogen (3.09%), phosphorus (1.37%), potassium (3.39%), calcium (2.37%) and magnesium (0.39%) and also gave highest net return i.e., Rs 16,61,790 /ha with highest B:C ratio of 3.77. Hence, it can be concluded that the treatment T8 is most suitable for improving the quality, yield and economic return of strawberry in central region of Punjub.

Indian mustard [Brassica juncea (L.) Czern and Coss.] is one of the most popular rabi oil seed crop in India. It’s belonging to family Cruciferae (Brassicaceae). It is mostly cultivated rabi, crop of Northern as well as North eastern region of India. Indian mustard contributes about 85 per cent of total rapeseed-mustard production in India [1]. Crucial Indian mustard growing states are Rajasthan (50%), Uttar Pradesh (12.3%), Haryana (11.2%), Madhya Pradesh (9.8%), Gujrat (6.5%) and West Bengal (5.1%). Indian mustard is affected by many major diseases like Fungal, Bacterial, Viral, and also parasitic nematode. In mustard maximum losses in yield occurs due to microbial diseases. Among the major disease viz., Alternaria blight (Alternaria brassicae, Alternaria brassicicola, Alternaria alternata), White rust (Albugo candida), Downey mildew (Peronospora parasitica), Powdery mildew (Erysiphe cruciferarum), Bacterial blight (Pseudomonas cannabina), and Sclerotinia stem rot (Sclerotinia sclerotiorum). Alternaria blight of Indian mustard is one of the most important disease which reduce quantity and quality of seed yield. Alternaria blight disease is one of the damaging disease among the major diseases of mustard causing up to 70 per cent losses in yield with no proven source of resistance against the disease reported till date in any of the hosts. To control the losses caused by pathogens many farmers are using fungicides to obtain very good yield. The present study was carried out to recognize the effect of different bioagents on control against Alternaria brassicicola under in-vitro condition. Four antagonists viz., Trichoderma viride, Trichoderma harzianum, Pseudomonas fluorescens and Bacillus subtilis, checked the growth of Alternaria brassicicola at point of their contact on culture medium. Among these, maximum inhibition (78.05%) of Alternaria brassicicola was observed in Trichoderma harzianum.
Slip‐behavior transitions of a heterogeneous linear fault
Authors: Yabe Suguru , Ide Satoshi
Published: November 2016

Geological faults have frictional heterogeneity. Here we investigate the slip behavior of such heterogeneous faults in the simplest situation, simulating antiplane shear slip along an infinite linear fault in a 2‐D elastic model space, subjected to constant loading by external stresses characterized by stiffness and plate‐motion velocity. The fault is discretized into many subfaults, each of which has either a velocity‐weakening (VW) or velocity‐strengthening (VS) friction law. We vary the proportion of the fault that is VW, revealing several different regimes of slip behavior. The first regime boundary, where stick‐slip behavior is initiated, is located at the proportion of VW zones such that each VW zone reaches its nucleation size. The other boundary is located where the spatially averaged a − b value of the rate and state friction law is close to zero. Below this density, the VW zone slips seismically, whereas the VS zone shows afterslip. In contrast, above this density, the entire fault slips simultaneously at the seismic slip velocity. We observe transitional behavior at the second boundary, where relatively slower deformation dominates. We also explore the slip behavior of faults using Cantor‐set distributions of frictional parameters. We propose that frictional heterogeneity on the fault may explain not only the diversity of seismic phenomena but also the observed scaling of frictional parameters, such as slip‐weakening distance or the fracture energy of ordinary earthquakes.
Reconstruction of gappy GPS coordinate time series using empirical orthogonal functions
Authors: Xu Chang
Published: November 2016

Data gaps are an unfortunate aspect of Global Positioning System (GPS) time series and that can (a) slow down the maximum likelihood estimation for stochastic noise modeling and (b) hamper signal processing algorithms that require evenly spaced data. Simply filling the data gaps by linear interpolation does not significantly bias the velocity estimates in the least squares analysis, whereas it may be less suitable for periodic term estimates for vertical GPS observations especially those that are sampled with wide gaps. We use iterative empirical orthogonal function‐based (EOF‐based) method to recover the gappy GPS coordinate time series and discuss their effects on periodic term estimates. Ordinary least squares estimation‐based (LSE‐based) interpolation (including trend, annual, and semiannual terms) is performed for comparison. We demonstrate our method with synthetic examples, as well as real daily coordinate time series of 10 GPS sites with more than 14 years of data. The optimal window size and number of dominant EOFs are determined using crossvalidation. We find that EOF‐based interpolation may bias amplitude estimates in the up component owing to the artificial signals introduced in the EOFs reconstruction. After skipping the “noisy” EOFs and including only EOFs that we are particularly interested, the bias becomes smaller. Moreover, EOF‐based interpolation outperforms LSE interpolation in the wavelet analysis of GPS time series particularly for situations with wide gaps. Offsets are also found to be essentially nuisance parameters that must be removed prior to applying interpolation.
Global rupture parameters for deep and intermediate‐depth earthquakes
Authors: Poli Piero , Prieto Germán A.
Published: November 2016

We investigate the global rupture parameters for deep and intermediate‐depth earthquakes. From measurements of rupture duration and radiated seismic energy we estimate stress drop, apparent stress, and radiation efficiency and obtain a detailed earthquake energy budget. From scaling of the source parameters we highlight differences between crustal and deep seismicity, with the latter showing larger fracture energies. The observed increase of radiation efficiency with depth suggests that rupture mechanism for deep and intermediate‐depth events differs. In agreement with previous studies we observe along‐strike variability of rupture properties for deep and intermediate‐depth earthquakes, correlating with slab morphology, plate age, or presence of volcanic structures.
The dynamics of surges in the 3 February 2015 avalanches in Vallée de la Sionne

Published: November 2016

Five avalanches were artificially released at the Vallée de la Sionne test site in the west of Switzerland on 3 February 2015 and recorded by the GEOphysical flow dynamics using pulsed Doppler radAR Mark 3 radar system. The radar beam penetrates the dilute powder cloud and measures reflections from the underlying denser avalanche features allowing the tracking of the flow at 111 Hz with 0.75 m downslope resolution. The data show that the avalanches contain many internal surges. The large or “major” surges originate from the secondary release of slabs. These slabs can each contain more mass than the initial release, and thus can greatly affect the flow dynamics, by unevenly distributing the mass. The small or “minor” surges appear to be a roll wave‐like instability, and these can greatly influence the front dynamics as they can repeatedly overtake the leading edge. We analyzed the friction acting on the fronts of minor surges using a Voellmy‐like, simple one‐dimensional model with frictional resistance and velocity‐squared drag. This model fits the data of the overall velocity, but it cannot capture the dynamics and especially the slowing of the minor surges, which requires dramatically varying effective friction. Our findings suggest that current avalanche models based on Voellmy‐like friction laws do not accurately describe the physics of the intermittent frontal region of large mixed avalanches. We suggest that these data can only be explained by changes in the snow surface, such as the entrainment of the upper snow layers and the smoothing by earlier flow fronts.
A physically based 3‐D model of ice cliff evolution over debris‐covered glaciers

Published: November 2016

We use high‐resolution digital elevation models (DEMs) from unmanned aerial vehicle (UAV) surveys to document the evolution of four ice cliffs on the debris‐covered tongue of Lirung Glacier, Nepal, over one ablation season. Observations show that out of four cliffs, three different patterns of evolution emerge: (i) reclining cliffs that flatten during the ablation season; (ii) stable cliffs that maintain a self‐similar geometry; and (iii) growing cliffs, expanding laterally. We use the insights from this unique data set to develop a 3‐D model of cliff backwasting and evolution that is validated against observations and an independent data set of volume losses. The model includes ablation at the cliff surface driven by energy exchange with the atmosphere, reburial of cliff cells by surrounding debris, and the effect of adjacent ponds. The cliff geometry is updated monthly to account for the modifications induced by each of those processes. Model results indicate that a major factor affecting the survival of steep cliffs is the coupling with ponded water at its base, which prevents progressive flattening and possible disappearance of a cliff. The radial growth observed at one cliff is explained by higher receipts of longwave and shortwave radiation, calculated taking into account atmospheric fluxes, shading, and the emission of longwave radiation from debris surfaces. The model is a clear step forward compared to existing static approaches that calculate atmospheric melt over an invariant cliff geometry and can be used for long‐term simulations of cliff evolution and to test existing hypotheses about cliffs' survival.
