Structures and stability of simple DNA repeats from bacteria
Authors: Brazda Vaclav , Fojta Miroslav , Bowater Richard P.
Published: January 2020

DNA is a fundamentally important molecule for all cellular organisms due to its biological role as the store of hereditary, genetic information. On the one hand, genomic DNA is very stable, both in chemical and biological contexts, and this assists its genetic functions. On the other hand, it is also a dynamic molecule, and constant changes in its structure and sequence drive many biological processes, including adaptation and evolution of organisms. DNA genomes contain significant amounts of repetitive sequences, which have divergent functions in the complex processes that involve DNA, including replication, recombination, repair, and transcription. Through their involvement in these processes, repetitive DNA sequences influence the genetic instability and evolution of DNA molecules and they are located non-randomly in all genomes. Mechanisms that influence such genetic instability have been studied in many organisms, including within human genomes where they are linked to various human diseases. Here, we review our understanding of short, simple DNA repeats across a diverse range of bacteria, comparing the prevalence of repetitive DNA sequences in different genomes. We describe the range of DNA structures that have been observed in such repeats, focusing on their propensity to form local, non-B-DNA structures. Finally, we discuss the biological significance of such unusual DNA structures and relate this to studies where the impacts of DNA metabolism on genetic stability are linked to human diseases. Overall, we show that simple DNA repeats in bacteria serve as excellent and tractable experimental models for biochemical studies of their cellular functions and influences.
ℓ1–2 minimisation for compressed sensing with partially known signal support
Authors: Zhang Jing , Zhang Shuguang , Meng Xuran
Published: January 2020

In this study, the authors mainly discuss the robust signal recovery by minimisation with incorporating prior support information, which is not considered in previous works. A robust recovery condition is established and an recovery error estimation is obtained, in particular, the obtained results generalise the state‐of‐the‐art ones. In addition, by proposing a modified algorithm, the numerical experiments show that incorporating prior support information for minimisation exhibits better recovery performance than standard minimisation.
Evaluating cognitive task result through heart rate pattern analysis
Authors: Yu Juan , Liu Guang Yuan , Wen Wan Hui , Chen Chuan Wu
Published: January 2020

The measurement of the right and wrong results of cognitive tasks has important applications in many commercial and educational areas such as the drivers’ training system, the simulation training and online learning system. This Letter aims to distinguish the heartbeat pattern of cognitively wrong responses to that of cognitively right responses based on the electrocardiogram (ECG) through 36 subjects with different professional backgrounds. The experimental design methods were double‐digit and five‐digit addition/subtraction, which were blindly selected by subjects from a black box. Through the R–R interval (RRI) series obtained from the ECG data, some linear, nonlinear and moment features were extracted to evaluate the cognitive task results by using pattern recognition methods. The binary classification of RRI datasets indicated that autonomic nerve patterns of the right and wrong cognitive heartbeat responses were distinguishable.
Lightweight approach to automated fault diagnosis in WSNs
Authors: Swain Rakesh Ranjan , Dash Tirtharaj , Khilar Pabitra Mohan
Published: January 2020

Automated fault diagnosis in wireless sensor networks (WSNs) has always been an essential field for the networks research community. In resource‐related constraints, the design of a lightweight method to automatically diagnose the fault in WSN is highly beneficial. In this study, the authors propose lightweight and less‐overhead approaches to diagnose hard and soft faults in WSNs automatically. Correctly, a lightweight checksum method is implemented for hard or crash fault detection. This method is capable of detecting multiple hard faults within a single path with the help of a timeout mechanism. For diagnosis of soft faults such as permanent, intermittent, and transient faults, they implement the Anderson–Darling (AD) statistical method. The AD test analyses how the sensor readings are fitted in a specific distribution for a tested significance level. Several testbed experiments are conducted to validate their hypotheses and implementations. The performance parameters that are evaluated in this work include fault detection accuracy, false alarm rate, and false‐positive rate. These parameters are evaluated about various fault probabilities in the network. They observe that the proposed lightweight schemes can diagnose both hard and soft faults in message complexity over the network, which makes it adaptable in practise.

Published: January 2020

An efficient synthesis process approach based on a chemical solution route is developed for the cadmium selenide quantum dots (CdSe QDs) that utilise photonic and optoelectronic device manufacturing. The developed route consists of dissolving the cadmium chloride (CdCl2. H2 O), 2‐mercaptoethanol and sodium selenide anhydrous (Na2SeO3). The different characterisation parameters such as ultraviolet (UV) absorbance, x‐ray diffraction (XRD), scanning electron microscopy, energy dispersive x‐ray and transmission electron microscopy (TEM) were employed in order to develop the CdSe QDs. When the sample was analysed from the UV–visible studies, the bandgap was about 2.16 eV, whereas the bulk CdSe bandgap was about 1.78 eV. The developed CdSe QDs possessed a cubic crystal structure with crystalline dimensions of about 4.86 nm. Its surface morphology and structure showed the smooth appearance of the surface. The result indicated agglomerated spheres. Ultimately, according to XRD and TEM results, the crystalline dimension was determined in good agreements.

Authors: Maharaj Zia , Pietrzak Jurek Rafal Tomasz , Sikhauli Nkhodiseni , van de Jagt Dick , Mokete Lipalo
Published: January 2020

Aim: The aim was to assess the seroprevalence of Human Immunodeficiency Virus (HIV) in non-haemophilic patients undergoing primary Total Joint Arthroplasty (TJA) at an academic hospital in South Africa.

Methods: A retrospective review of all Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA) patients from January 2017 to December 2018 was conducted. All patients awaiting TJA were offered HIV screening and their demographic data were recorded. Consenting patients were tested or the refusal of testing was documented. The CD4+ T-cell count (CD4+) and viral load (VL) was measured for all HIV-positive patients and newly diagnosed patients were initiated on Highly Active Antiretroviral Treatment (HAART).

Results: We included 1007 patients in the study. The TJA population HIV seroprevalence was 10.7% (n = 108). The seroprevalence for THA was 14.9% (n = 78) and that for TKA was 6.2% (n = 30). There were 93 patients (9.2%) who refused screening. There were 12 (15.4%) and 3 patients (10%) that were newly diagnosed in the THA and TKA seropositive populations, respectively. The average CD4+ for THA and TKA was 569 cells/mm3 (105–1320) and 691 cells/mm3 (98–1406), respectively. The VL was undetectable in 75.9% (n = 82) of HIV-positive patients. Overall 12 HIV-positive patients (11.12%) had CD4+ <200 cells/mm3, 8 of these patients (66%) were newly diagnosed. The average age of the seropositive population was 58 ± 6.5 years and 66 ± 8.5 years for THA and TKA, respectively (p = 0.03). Femoral head osteonecrosis was the underlying pathology for 65.38% (n = 51) of seropositive patients for THA.

Conclusion: The seroprevalence of HIV in patients undergoing THA in our South African institution is greater than the seroprevalence in the general population. The seroprevalence of HIV in THA is significantly greater than that in TKA. This may reflect the association between HIV, HAART and hip joint degeneration. Our findings draw attention to the significant burden HIV has on TJA.

Published: January 2020

Background and study aims Endoscopic mucosal resection (EMR) is increasingly used for the treatment of large colonic polyps (≥ 20 mm). A drawback of EMR is local adenoma recurrence. Therefore, we studied the impact of argon plasma coagulation (APC) of the EMR edge on local adenoma recurrence.

Patients and methods This was a retrospective study of patients with laterally spreading tumors (LST) ≥ 20 mm, who underwent EMR from January 2009 to August 2018 and follow-up endoscopic assessment. A cap-fitted endoscope was used to assess completeness of resection by systematically inspecting the EMR defect for any macroscopic disease. This was followed by forced APC of the resection edge followed by clip closure of the defect. Surveillance colonoscopy was performed at 6 months after resection to detect recurrence.

Results Two hundred forty-six patients met the inclusion criteria. Most were female (53 %) and white (80 %), with a Median age of 64 years. Median polyp size was 35 mm (interquartile range, 30–45 mm). Most polyps were located in the right colon (77 %) and were removed by piecemeal EMR (70 %). Eleven patients (5 %) had residual tumor at the resection site.

Conclusions We observed low adenoma recurrence after argon plasma coagulation of the EMR edge with a cap fitted colonoscope in patients with LST ≥ 20 mm of the colon, which requires further validation in a randomized controlled study.
Derzeitiger Stand zur primären Neuroprotektion beim Glaukom
Authors: Reinehr Sabrina , Grotegut Pia , Tsai Teresa , Wagner Natalie , Joachim Stephanie C.
Published: January 2020

Angesichts der zunehmenden Alterung unserer Gesellschaft wird es in den kommenden Jahren zu einem Anstieg von starken Sehbinderungen und Erblindungen, auch durch das Glaukom, kommen. Aktuell beschränken sich die Therapieoptionen lediglich auf die Behandlung der Symptome, was im besten Fall zu einer Verlangsamung der Progression führt, jedoch nicht zur Heilung. Es ist daher notwendig, neue Therapiestrategien zu entwickeln, um das Glaukom adäquat und effektiv behandeln zu können und damit die Lebensqualität der Betroffenen zu verbessern. Ein möglicher Ansatz scheint die primäre Neuroprotektion darzustellen, die unabhängig von einer Drucksenkung wirkt. Es gibt Hinweise, dass Komponenten des Immunsystems eine Rolle im Rahmen der Erkrankung bzw. des Unterganges der retinalen Ganglienzellen spielen. So wurden Hinweise auf eine Beteiligung von Hitzeschockproteinen, des Komplementsystems, aber auch von Mikrogliazellen gefunden. Daher scheint eine therapeutische Modulation dieser Faktoren ein interessanter neuer Angriffspunkt für die Neuroprotektion zu sein. Untersuchungen im Tiermodell zeigten bspw., dass eine Inhibition des Komplementsystems oder der Mikroglia zu einem Schutz führt. Durch eine Modulation der Hitzeschockproteine könnten entweder deren protektive Eigenschaften gefördert oder ihre schädliche Funktion gehemmt werden, um so einen Glaukomschaden zu verhindern. Diese neuroprotektiven Ansätze könnten in Zukunft die Therapieoptionen von Glaukompatienten erweitern.

Comparing Maximal Mean and Critical Speed and Metabolic Powers in Elite and Sub-elite Soccer
Authors: Lord Cameron , Blazevich Anthony John , Abbiss Chris Richard , Drinkwater Eric James , Ma’ayah Fadi
Published: January 2020

The quantification of maximal mean speed (MMS), maximal mean metabolic power (MMPmet), critical speed (CS) and critical metabolic power (CPmet) was conducted over full A-League (elite) and National Premier League (NPL; sub-elite) seasons. Comparisons were made between levels of soccer competition and playing positions (i. e. centre backs, full backs, central midfielders, wide midfielders and strikers). A symmetric moving average algorithm was applied to the GPS raw data using specific time windows (i. e. 1, 5, 10, 60, 300 and 600 s) and maximal values were obtained. Additionally, these maximal values were used to derive estimates of CS and CPmet. Maximal mean values, particularly during smaller time windows (i. e. 1 and 5 s), were greater in A-League match play. Only MMPmet1 was identified as being consistently different between competitions (P=<0.001–0.049) in all playing positions. Significance was only observed in CS (P=0.005) and CPmet (P=0.005) of centre backs between competitions. Centre backs were identified as the least energy demanding playing position. The present findings suggests that both maximal mean and critical analyses are suitable alternatives to common absolute distance and speed assessments of match running performance during competitive matches.
Distribution of sugar-sweetened beverage sales volume by sugar content in the United States: implications for tiered taxation and tax revenue
Authors: Powell Lisa M. , Andreyeva Tatiana , Isgor Zeynep
Published: January 2020

This study draws on data on sales volume, brand-level market shares, and sugar content to calculate the distribution of sugar-sweetened beverage (SSB) sales volume by sugar content, propose sugar content thresholds for a tiered tax structure, and estimate tax revenue. The most common SSBs sold had 26 g of sugar/8-oz serving; 70.8% had ≥ 25 g of sugar/8-oz serving, 16.9% were in the 10–15 g range, and 8.7% were in the 16–20 g range. A tiered tax with cut points at < 20 g and < 5 g of sugar/8-oz serving is proposed. A tax of 1¢/oz for SSBs in the second tier and 2¢/oz in third tier is projected to raise $18.2 billion in tax revenue similar to the 1.5¢/oz flat tax projection ($18.0 billion) but would yield 9% lower SSB volume. Understanding the distribution of SSB sales volume by sugar content informs policymakers on tiered tax structures, which may discourage consumption of SSBs with high levels of sugar and incentivize reformulation.
Passive wideband concentric rings resonator for vocal cords abnormalities detection: Application on larynx cancer pathologies
Authors: Matta Sandrine , Diab Daher , Saad Nadine , Ishac Dany , Nassar Georges
Published: January 2020

This work addresses the study and design of a diagnostic device consisting of a thin-film sensor array based on 8-mm concentered rings, acting as an autonomous acoustic sensor covering a wide range of resonance frequencies (0.1 KHz–2 MHz). In addition to its advantageous shape, this device integrates both the active vibratory element and the embedded electronics dedicated to coding, control, and analysis. The results show that the experimental device could be the basis of a telemedical platform for the objective assessment and monitoring of chronic laryngeal dysphonia through the spectro-temporal analysis of the vibration of the vocal cords. Furthermore, this non-invasive, non-intrusive protocol does not require the physical cooperation of the patient.

Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of nonequilibrium electronic processes, transient states in chemical reactions, or the interplay of electronic and structural dynamics offers fascinating opportunities for future research. Combining valence-band and core-level spectroscopy with photoelectron diffraction for electronic, chemical, and structural analyses requires few 10 fs soft X-ray pulses with some 10 meV spectral resolution, which are currently available at high repetition rate free-electron lasers. We have constructed and optimized a versatile setup commissioned at FLASH/PG2 that combines free-electron laser capabilities together with a multidimensional recording scheme for photoemission studies. We use a full-field imaging momentum microscope with time-of-flight energy recording as the detector for mapping of 3D band structures in (kx, ky, E) parameter space with unprecedented efficiency. Our instrument can image full surface Brillouin zones with up to 7 Å−1 diameter in a binding-energy range of several eV, resolving about 2.5 × 105 data voxels simultaneously. Using the ultrafast excited state dynamics in the van der Waals semiconductor WSe2 measured at photon energies of 36.5 eV and 109.5 eV, we demonstrate an experimental energy resolution of 130 meV, a momentum resolution of 0.06 Å−1, and a system response function of 150 fs.
Toolbox approach for quasi-relativistic calculation of molecular properties for precision tests of fundamental physics
Authors: Gaul Konstantin , Berger Robert
Published: January 2020

A generally applicable approach for the calculation of relativistic properties described by one-electron operators within a two-component wave function approach is presented. The formalism is explicitly evaluated for the example of quasirelativistic wave functions obtained within the zeroth order regular approximation (ZORA). The wide applicability of the scheme is demonstrated for the calculation of parity (P) and time-reversal (T  ) symmetry violating properties, which are important for searches of physics beyond the standard model of particle physics. The quality of the ZORA results is shown exemplarily for the molecules RaF and TlF by comparison with data from four-component calculations as far as available. Finally, the applicability of RaF in experiments that search for P,T-violation not only in the electronic but also in the quark sector is demonstrated.

Published: January 2020

We have studied the strain induced modifications in the structural, electronic, and vibrational properties of beryllium chalcogenide (groups II–VI) BeX (where X = S, Se, and Te) compounds by employing first-principles calculation within the framework of density-functional theory based on the plane-wave pseudopotential method with implementation of the local-density approximation functional. We have gradually applied biaxial strain on BeX compounds and observed changes in the structure of these compounds. The calculated structural properties such as lattice parameter, bulk modulus, and bandgap are in good agreement with the previously reported theoretical and experimental values. It is found that the calculated bandgaps are indirect from the Γ → X direction and vary with the applied strain. It is also confirmed by the density of states calculations. To study the dynamical stability of BeX compounds, we have calculated the vibrational properties. The calculated bandgap and phonon frequencies vary with the applied strain. For a higher value of the applied strain, we found imaginary phonon frequencies for all three compounds. The bandgap and phonon frequencies decrease as we move from a lower to a higher atomic number (i.e., from S to Te) for BeX compounds.
Analytical techniques for linear response formula of equilibrium states
Authors: Castro Armando
Published: January 2020

In this paper, we expose some of the analytical framework used to prove the differentiability of equilibrium states probabilities with respect to the dynamics. We explore the relationship between Birkhoff metrics in cones and their corresponding anisotropic spaces and prove some useful folklore theorems. We apply that framework to revisit several examples recently studied in the research works about equilibrium states.
Singularity theorems and the inclusion of torsion in affine theories of gravity
Authors: Luz Paulo , Mena Filipe C.
Published: January 2020

We extend the scope of the Raychaudhuri–Komar singularity theorem of general relativity to affine theories of gravity with and without torsion. We first generalize the existing focusing theorems using time-like and null congruences of curves which are hypersurface orthogonal, showing how the presence of torsion affects the formation of focal points in Lorentzian manifolds. Considering the energy conservation on a given affine gravity theory, we prove new singularity theorems for accelerated curves in the cases of Lorentzian manifolds containing perfect fluids or scalar field matter sources.
A fluid-based active plasmonic grating filter
Authors: Wu Jun , Du Yaqiong , Xia Jun , Zhang Tong , Lei Wei , Wang Baoping
Published: January 2020

An advanced electrowetting fluid manipulation technology is adopted to realize the dynamic redistribution of the surrounding fluid media of silver grating, and thereby, the surface plasmon resonance is real-timely modulated. The results indicated that the wavelength of the resonance absorption peak of the designed fluid-based grating filter can be tuned smoothly and continuously by simply varying the electrowetting voltage. More importantly, the modulation is reversibly operated, fast responded, and energy efficient and can be flexibly integrated. By combining this electrowetting filtering function with the appropriate structural parameters according to the practical demands, such novel design can realize the fine-tuning of light covering the entire visible spectrum.
dc and ac transport in few-layer black phosphorus
Authors: Tahir M. , Krstajić P. M. , Vasilopoulos P.
Published: January 2020

The multilayer band structure of black phosphorus (BP) is highly anisotropic, and its bandgap is tunable by applying a perpendicular electric field Ez. Within a linear response theory, we study dc and ac transport in few-layer BP, as functions of the Fermi energy, temperature, or frequency, in the presence of a Zeeman field. The current response to an in-plane electric field along two perpendicular directions is anisotropic and reflects that of the energy spectrum. In addition, we study the Hall conductivity and power absorption spectrum. The Hall conductivity vanishes, but the power spectrum P(ω) shows a considerable structure as a function of the normalized frequency α=ℏω/2Δ and/or of the bandgap 2Δ tuned by Ez. In particular, a clear maximum occurs in the difference between spin-up and spin-down contributions to P(ω). When potassium (K) atoms are deposited on top of BP, the anisotropy in the current response is stronger and the power spectrum is further modified. The results may be pertinent to the development of phosphorene-based applications.
Effect of insertion of bathocuproine buffer layer at grating-structured cathode–organic-layer interface in bulk-heterojunction solar cells
Authors: Sakomura Masaru , Yokokura Yuya , Takagi Yusuke , Ueda Kazuyoshi
Published: January 2020

A grating-structured interface of a poly(3-hexylthiophene) (P3HT) and n-type [6,6]-phenyl-C61-butyric acid methyl ester (PCBM)-based bulk-heterojunction (BHJ) photovoltaic (PV) cell was designed and fabricated to obtain a desirable thickness distribution of the deposited bathocuproine (BCP) buffer layer to efficiently utilize its potentials. As a master mold of the grating-structure, a commercially available recordable digital versatile disc (DVD-R) substrate was employed. The grating-structured surface of the P3HT:PCBM layer was successfully produced by duplication from a poly(dimethylsiloxane) secondary mold using the spin cast molding technique. From morphological observations of the grating-structured surface covered with vapor-deposited BCP, we roughly estimated the ratio of the BCP thickness at “walls” to that at “top” and “bottom” regions to be ∼0.5. The grating-type BHJ PV cell with a 5-nm-thick BCP layer exhibited the maximum power-conversion efficiency (ηp) of 3.51%. Compared with the conventional flat-type BHJ PV cell with a 20-nm-thick BCP layer, the performance of the grating-type BHJ PV cell with a 20-nm-thick BCP layer was remarkably improved, owing to the contribution of the wall side contact, which provides a lower-barrier path of the electrons toward the cathode through the thinner BCP layer.

Published: January 2020

Density distributions of negative hydrogen (H−) ions and negative deuterium (D−) ions were measured with the laser photodetachment method in the extraction region of the negative ion source. The distribution of H− ion density peaks at the center of the ion source, while that of the D− ion shows a flatter profile in the direction parallel to the plasma grid. The positive ion densities of hydrogen and deuterium estimated from the positive saturation current indicate similar profiles with different amounts close to the grid. The difference in the H− ion and D− ion distributions can be explained by the difference in the negative ion yield and the survival probability of the ions due to the isotope effect.

Published: January 2020

Self-assembly is an important process in biological systems and also a promising avenue toward dynamic and responsive micro- and nano-technologies. This study discusses the non-equilibrium self-assembly of inherently magnetic bacteria oriented perpendicular to a solid surface. An interplay between hydrodynamic and magnetic interactions leads to stable three-dimensional clusters in the long-time regime, which may be programmatically assembled, disassembled, and translated across a surface. The implications of the findings for the rational design of non-equilibrium self-assembly in general are discussed.

We prepared Fe-Ni thick-films (> 1 μm) using an electroless deposition method and evaluated the magnetic properties and the crystal structures. The deposition rate depended on the concentration of dimethylamine-borane (DMAB), which is a reducing agent used in the present study, and we obtained a high deposition rate (> 10 μm/h) for Fe30Ni70 films when the DMAB concentration is higher than 3 g/L. From structural analyses of the films, we found that the films have very fine fcc Fe-Ni crystals in the amorphous magnetic phase. From the investigation of Co additives for the improvement in the surface conditions, we confirmed that a small amount of Co effectively works to obtain the smooth surfaces. As a result, we could obtain the Fe-Ni-system thick-films with low coercivity (50 A/m) and smooth surfaces.
Spray-coated magnetic powder composite planar inductor for compact IoT sensor node
Authors: Hara T. , Yamaguchi M.
Published: January 2020

A spray coating process of magnetic powder composite material is proposed in this paper for planar inductors and transformers for small DC/DC converter. This is a low temperature (≤150 °C) process that is usable for ferrites and extensively other magnetic powders and flakes. A commercially available Ni-Cu-Zn spinel ferrite particles and epoxy resin composite is applied for a 3 x 3 mm2 planer spiral inductor whose coil has 1 μm-thick, line/space =56/9 μm, and 10 turns made on a Si substrate, and exhibited inductance enhancement from from 157 nH to 205 nH (30%) without any resistance increase, up to 5 MHz. Physical stress by the proposed spray coating process can be negligible, judging from the well increased inductance and low resistance.

Authors: Shin Kyung-Hun , Bang Tae-Kyoung , Seo Sung-Won , Kim Chang-Woo , Choi Jang-Young
Published: January 2020

This paper deals with analytical and experimental study of permanent magnet linear synchronous machines with horizontally magnetized permanent magnets. Six subdomains are defined as analysis domains considering end effects, slotting effects, and flux pass iron poles. The governing equations for each domain are derived from the Maxwell equation and the constitutive relations in electromagnetic theory, and the second-order differential equations are calculated by using the Sturm-Liouville theory. By applying the boundary conditions, analytical solutions in each area are derived, and electromagnetic performance and generating characteristics can be predicted based on the derived analytical solutions. The proposed analytical method is validated by comparison with finite element and experimental results.

Pulse propagation in gravity currents

Published: January 2020

Real world gravity current flows rarely exist as a single discrete event, but are instead made up of multiple surges. This paper examines the propagation of surges as pulses in gravity currents. Using theoretical shallow-water modeling, we analyze the structure of pulsed flows created by the sequential release of two lock-boxes. The first release creates a gravity current, while the second creates a pulse that eventually propagates to the head of the first current. Two parameters determine the flow structure: the densimetric Froude number at the head of the current, Fr, and a dimensionless time between releases, tre. The shallow-water model enables the flow behavior to be mapped in (Fr, tre) space. Pulse speed depends on three critical characteristic curves: two that derive from the first release and correspond to a wavelike disturbance which reflects between the head of the current and the back of the lock-box and a third that originates from the second release and represents the region of the flow affected by the finite supply of source material. Pulses have non-negative acceleration until they intersect the third characteristic, after which they decelerate. Variations in pulse speed affect energy transfer and dissipation. Critically for lahars, landslides, and avalanches, pulsed flows may change from erosional to depositional, further affecting their dynamics. Gravity current hazard prediction models for such surge-prone flows may underpredict risk if they neglect internal flow dynamics.
