Oceanic eddies induce a rapid formation of an internal wave continuum
Authors: Yang Luwei , Barkan Roy , Srinivasan Kaushik , McWilliams James C. , Shakespeare Callum J. , Gibson Angus H. 
Published: December 2023

AbstractOceanic internal waves are a major driver for turbulent mixing in the ocean, which controls the global overturning circulation and the oceanic heat and carbon transport. Internal waves are observed to have a continuous energy distribution across all wave frequencies and scales, commonly known as the internal wave continuum, despite being forced at near-inertial and tidal frequencies at large scales. This internal wave continuum is widely thought to be developed primarily through wave-wave interactions. Here we show, using realistic numerical simulations in the subpolar North Atlantic, that oceanic eddies rapidly distribute large-scale wind-forced near-inertial wave energy across spatio-temporal scales, thereby forming an internal wave continuum within three weeks. As a result, wave energy dissipation patterns are controlled by eddies and are substantially enhanced below the mixed layer. The efficiency of this process potentially explains why a phase lag between high-frequency and near-inertial wave energy was observed in eddy-poor regions but not in eddy-rich regions. Our findings highlight the importance of eddies in forming an internal wave continuum and in controlling upper ocean mixing patterns.

Abstract
Background
Cataract diagnosis typically requires in-person evaluation by an ophthalmologist. However, color fundus photography (CFP) is widely performed outside ophthalmology clinics, which could be exploited to increase the accessibility of cataract screening by automated detection.

Methods
DeepOpacityNet was developed to detect cataracts from CFP and highlight the most relevant CFP features associated with cataracts. We used 17,514 CFPs from 2573 AREDS2 participants curated from the Age-Related Eye Diseases Study 2 (AREDS2) dataset, of which 8681 CFPs were labeled with cataracts. The ground truth labels were transferred from slit-lamp examination of nuclear cataracts and reading center grading of anterior segment photographs for cortical and posterior subcapsular cataracts. DeepOpacityNet was internally validated on an independent test set (20%), compared to three ophthalmologists on a subset of the test set (100 CFPs), externally validated on three datasets obtained from the Singapore Epidemiology of Eye Diseases study (SEED), and visualized to highlight important features.

Results
Internally, DeepOpacityNet achieved a superior accuracy of 0.66 (95% confidence interval (CI): 0.64–0.68) and an area under the curve (AUC) of 0.72 (95% CI: 0.70–0.74), compared to that of other state-of-the-art methods. DeepOpacityNet achieved an accuracy of 0.75, compared to an accuracy of 0.67 for the ophthalmologist with the highest performance. Externally, DeepOpacityNet achieved AUC scores of 0.86, 0.88, and 0.89 on SEED datasets, demonstrating the generalizability of our proposed method. Visualizations show that the visibility of blood vessels could be characteristic of cataract absence while blurred regions could be characteristic of cataract presence.

Conclusions
DeepOpacityNet could detect cataracts from CFPs in AREDS2 with performance superior to that of ophthalmologists and generate interpretable results. The code and models are available at https://github.com/ncbi/DeepOpacityNet (https://doi.org/10.5281/zenodo.10127002).
Scale‐preserving shape reconstruction from monocular endoscope image sequences by supervised depth learning
Authors: Masuda Takeshi , Sagawa Ryusuke , Furukawa Ryo , Kawasaki Hiroshi 
Published: December 2023

AbstractReconstructing 3D shapes from images are becoming popular, but such methods usually estimate relative depth maps with ambiguous scales. A method for reconstructing a scale‐preserving 3D shape from monocular endoscope image sequences through training an absolute depth prediction network is proposed. First, a dataset of synchronized sequences of RGB images and depth maps is created using an endoscope simulator. Then, a supervised depth prediction network is trained that estimates a depth map from a RGB image minimizing the loss compared to the ground‐truth depth map. The predicted depth map sequence is aligned to reconstruct a 3D shape. Finally, the proposed method is applied to a real endoscope image sequence.

Case Description A patient presented with new onset atrial fibrillation and heart failure. Workup including open surgery revealed a primary cardiac lymphoma.
Conclusion Cardiac tumors present with a variety of symptoms and are best evaluated by echocardiogram, computed tomography angiography, and magnetic resonance imaging. Tissue diagnosis is necessary. Although primary cardiac lymphoma is rare, long-term survival after chemotherapy and rituximab is superior to other cardiac malignancies.
Calibrated weighted permutation test detects ancient language connections in the Circumpolar area
(Chukotian-Nivkh and Yukaghir-Samoyedic)*
Authors: Kassian Alexei S. , Starostin George , Zhivlov Mikhail , Spirin Sergey A. 
Published: December 2023

Abstract
Relationships between universally recognized language families represent a hotly debated topic in historical
linguistics, and the same is true for correlation between signals of genetic and linguistic relatedness. We developed a weighted
permutation test which represents the classical permutation tests with weights introduced for individual Swadesh concepts
according to their typological stability. Further, the obtained values were calibrated on a negative control group to override
non-uniform distribution of phonemes within the Swadesh wordlist. We applied the calibrated permutation test to the basic
vocabularies of nine languages and reconstructed proto-languages to show that three groups of circumpolar language families in the
Northern Hemisphere show evidence of relationship through common descent or borrowing in the basic vocabulary:
[Chukotko-Kamchatkan, Nivkh]; [Yukaghir, Samoyedic]; and [Yeniseian, Na-Dene, Burushaski]. The former two pairs showed the most
significant signals of language relationship. Our findings further support some hypotheses on long-distance language relationships
previously put forward based on linguistic methods but lacking universal acceptance.
On an even playing field of haiku making
Authors: Matsumoto Yoshiko , Maeda Harumi , Wan Emily Yu , Liao Hsiao-Wen 
Published: December 2023

Abstract
To help older adults living with cognitive impairments to engage in positive social interactions and maintain
verbal creativity, intergenerational small-group sessions of haiku creation and appreciation activity were
conducted online during the pandemic. Haiku, a short 17-syllable form of poetry originating in Japan, conveys
simple yet emotive seasonal images free from the complexity or logical continuity required of prose. Accordingly, it offers anyone
the challenge of an unfamiliar activity while minimizing impediment from linguistic and memory difficulties. The participants’
interactions during the activity and post-session interviews reveal that for both young and old, the haiku
creation format facilitated self-expression and sharing of personal narratives. The key to meaningful interaction was the equal
positioning of persons with and without cognitive impairments and their efforts to understand their interlocutor’s purpose and
conversational direction. The study encourages further studies in pragmatics centered on affect-oriented communication.
Physical insights of interface traps and self-heating effect on electrical response of DMG FinFETs in overlap and underlap configurations: analog/RF perspective
Authors: Chaudhary Rashi , Saha Rajesh 
Published: December 2023

Abstract
This paper presents a thorough analysis on analog/RF parameters including interface trap charges (ITCs) of two different densities of states (DOS) along with self-heating on the performance of DMG FinFETs in Overlap and Underlap configurations. Initially, the independent simulations for acceptor ITCs and Self-heating in conventional device reveals that performance degradation caused by Self-heating is more prominent (25.03%) than uniform acceptor ITCs (9.46%). In consecutive step, the cumulative impact of both acceptor ITCs and Self-heating on DC and RF/analog parameters are carried out. Investigation reveals that as the impact of self-heating is larger in overlap configuration, the degradation in drain current is higher in overlap configuration (45.2%, 54.5%) as compared to conventional (30.4%, 40.96%) and underlap (37.2%, 52.8%) configurations for both Uniform and Gaussian trap distributions, respectively.

Abstract
The microstructure and temperature of martensitic transformation of Ni44Fe19Ga27Co10 single crystals after aging at temperatures from 623 K to 1173 K were studied by electron microscopy and differential scanning calorimetry. The temperature ranges of the second phase precipitation, their lattice structure and volume fraction, and also the modification of the nanodomain structure of the L21+B2 high-temperature phase were determined in dependence on aging temperature. The influence of microstructure parameters on the martensitic transformation temperatures, transformation intervals and thermal hysteresis has been discussed.
Computational model of interacting system dynamics of calcium, IP3 and β-amyloid in ischemic neuron cells
Authors: Pawar Anand , Pardasani Kamal Raj 
Published: December 2023

Abstract
The study of single independent dynamics of calcium ([Ca2+]), IP3, and β-amyloid (Aβ) in neurons provide limited information. Some attempts are reported for the dynamics of two interacting systems of [Ca2+] and IP3, and calcium and Aβ, which gave some novel insights about the phenomena. However, the interactions of these three systems have not been analyzed till date in neurons. Therefore, a novel model is constructed to study the interactions of the spatiotemporal systems of [Ca2+], IP3, and Aβ in neurons. A two-way feedback mechanism between [Ca2+] and IP3, and [Ca2+] and Aβ has been incorporated into the model. The model is formulated by coupling three reaction-diffusion equations of [Ca2+], IP3 and Aβ, respectively. This coupling automatically takes care of the indirect two-way feedback process between IP3 and β-amyloid in neuron cells. The finite element method (FEM) with the Crank-Nicolson scheme (CNS) is utilized to study the contribution of various ER-associated processes like RyR, IP3R, SERCA pump, buffer approximation, etc on the neuronal interactions of [Ca2+], IP3, and β-amyloid during Ischemia. The numerical findings provide novel insights into alterations in ER handling during Ischemia, resulting in disturbances in the neuronal calcium, IP3, and Aβ levels, which may cause the advancement of Alzheimer’s illness and be responsible for neurotoxicity and cell death.
Improving the accuracies of estimating environment parameters via initial probe-environment correlations
Authors: Zhang Chenxia , Gong Beili 
Published: December 2023

Abstract
We investigate the effect of the initial probe-environment correlations in estimating environment parameters. The probe constructed by two qubits, i.e. the two-qubit probe, is coupled with separate bosonic reservoirs and prepared in the product state. With the initial probe-environment correlations, we derive the analytic quantum Fisher information (QFI) and the corresponding quantum signal-to-noise ratio (QSNR) to quantify the estimation accuracy of environment parameters. The QFI and the QSNR increase when estimating cut-off frequency, coupling strength, and temperature, respectively, demonstrating that the initial probe-environment correlations can be used to improve the accuracy of estimating the environment parameters in the estimation scheme of two-qubit probes.
Dimensional reduction of dynamical systems by machine learning: automatic generation of the optimum extensive variables and their time-evolution map
Authors: Nogawa Tomoaki 
Published: December 2023

Abstract
A framework is proposed to generate a phenomenological model that extracts the essence of a dynamical system (DS) with large degrees of freedom using machine learning. For a given microscopic DS, the optimum transformation to a small number of macroscopic variables, which is expected to be extensive, and the rule of time evolution that the variables obey are simultaneously identified. The utility of this method is demonstrated through its application to the nonequilibrium relaxation of the three-state Potts model.

Published: December 2023

Abstract
The safety design of uncontained engine rotor failure for civil aircraft primary flight control systems is more difficult than other airborne systems. This paper presents a safety design method that establishes a two-stage collision model inspection mechanism and introduces an automatic analysis algorithm in the process of comprehensive impact analysis of the cascade system. The method applies to the detailed design stage of civil aircraft systems. It can reduce the difficulty of the safety analysis process and improve the accuracy of the analysis results. The verification of a civil aircraft primary flight control system design shows that after using the safety design method, the time cost of the analysis process is significantly reduced, and the analysis results are more accurate, thereby reducing the difficulty of design changes.

Authors: Cai Jing 
Published: December 2023

Abstract
Aircraft structural design requires lightweight design on the premise of meeting various performances. The number of hinge ribs in the aircraft trailing edge compartment is large, so it is very important to optimize the structure to achieve lightweight design. In this paper, the topology optimization algorithm is used to optimize the hinge ribs of the trailing edge cabin, and the secondary design is carried out according to the topology optimization results to achieve lightweight. The optimized rear edge cabin hinge rib can meet the requirements of strength, rigidity, process, manufacturing, etc., and the weight is greatly reduced compared with before optimization.

Abstract
Aiming at the problem that the traditional rigid exposure experiment platform takes up too much launch space and consumes high launch cost, a thick panel kirigami method is used to propose a deployable thick panel model for the exposure experiment platform, which realizes the plane of the thick panel. In the unfolding design, the unfolding process simulation of the structure was carried out, the influence of different hinge position drives on the dynamic behavior of the structure unfolding was studied, and the kinematics laws of the structure unfolding process under different driving modes were summarized. The new deployable exposure experiment platform provides new ideas for the development and application of practical engineering in the future, and the dynamic simulation also provides a driving strategy for it.
The Design of Phugoid Mode Stabilization in Angle of Attack Protection Control Law
Authors: Zhang Yuqi , Xu Dongguang , Zheng Xiaohui 
Published: December 2023

Abstract
To achieve the requirement of maintaining the angle of attack, the design of the angle of attack (AOA) protection control law often causes instability in the pitch attitude and generates phugoid mode oscillations. Conversely, adding a damping ratio of phugoid to suppress the oscillations would reduce the stability of the angle of attack and the maneuverability of the aircraft. Therefore, when designing the AOA protection control law, it is necessary to choose the appropriate damping ratio to allow the aircraft to have a certain balance between maneuverability and stability. At present, people do not pay enough attention to this, but the resulting aviation accidents make this problem urgent to be solved. In this paper, based on the general modeling process, the linear model of a sample aircraft is established. Different gain values are designed according to the different needs of different flight phases for aircraft maneuverability and stability. The simulation shows that in the flight phase, the phugoid mode stabilization control law designed by the eigenstate assignment method (EA) can reduce the phugoid oscillation effectively, while in the landing flare phase when maneuverability is more important, it provides a greater degree of maneuverability.
Error Correction Method of Platform Displacement for Large Load Static Test
Authors: Sun Zijie , Tang Xiaojun , Yang Qifan , Xin Liang 
Published: December 2023

Abstract
The test platform is an indispensable supporting bearing structure in static tests, which is mainly used to fix test products, simulate the real loading boundary, and provide better operation space for measurement. With the large-scale and complicated spacecraft structure, the static test platform tends to be large-scale, and the displacement measurement error of the static test platform under large load conditions cannot be ignored. The conventional error correction method only uses the displacement value of the monitoring point at the corresponding position of the platform to compensate, ignoring the comprehensive influence of the six degrees of freedom displacement for the test platform on the displacement measurement of the specimen. When it is used for the error correction of the static test of large spacecraft structures, there is a large measurement error affected by the structural size. In view of this, according to the static test requirements of a large spacecraft, a large bearing static test platform with a lateral load of 22 T and a longitudinal load of 52 T is designed, and a displacement measurement error correction method based on six degrees of freedom is proposed. Through the static test of a large spacecraft structure, the method can effectively reduce the displacement measurement error caused by the displacement of the test platform, and the error correction rate can reach 20%.

Published: December 2023

Abstract
Here, we presented a heterogeneous Magneto Resistance Tilted Polarizer-based Spin Torque Nano Oscillator [MRTP-STNO] and theoretically included Current Induced Oersted Field [CIOF] via the macro-spin domain. The dynamics of magnetization provoked by Spin Transfer Torque [STT] are studied by solving Landau-Lifshitz-Gilbert-Slonczewski [LLGS] equation. In this device, β is the independent tilt angle of the fixed layer. In contrast, θ is the angle between the free layer magnetization and the easy axis of the device, respectively. Angles β and θ can be varied from 10° to 90° as an increment of 10°. The maximum obtained frequency of the device of about 215 GHz, and PSD of 1.7 μW/mA2/GHz with CIOF as 50 kA/m. We suggest the device is an ideal candidate for ultra High-Frequency and unveils a new path for foreseeable spintronic devices.

Published: December 2023

Abstract
Cu-Ni films are electrodeposited at a cathodic current of 10 mA via galvanostatic mode on ITO-coated glass substrates. It found by X-ray diffraction that the films crystalized into fcc structure with the highest intensity corresponding to (111) plane at a two-theta value of 43°. The presence of binding energy peaks at 856.57 eV, 861 eV, 933 eV, and 952 eV observed in X-ray photoelectron spectroscopy have confirmed the presence of nickel oxide/hydroxide and copper oxide/hydroxide, respectively. Tafel polarization studies conducted in 3.5 wt. % sodium chloride solution shows the shifts in Ecorr towards the positive side and decrease of Icorr with the passage of exposure time is attributed to the formation of protective oxides/hydroxides layers of Cu and Ni elements in the films.
Synthesis and study of structural and electrical transport properties of Ni and Zr doped Y-type Ba-Co hexa-ferrite
Authors: Singh G. , Kaur R. , Ghumman S. S. 
Published: December 2023

Abstract
In present study, Co2 Y-type barium hexaferrite samples of Ba2Co2NixZrxFe12-2xO22 (with x =0.5 and 1.0) were synthesized using the solid-state reaction method with sintering temperatures of 900°C and 1200°C. To examine the effects of Ni-Zr doping on the crystal structure and dielectric properties of Y-type barium cobalt hexaferrite, samples were characterized using EDS, XRD and SEM techniques. The XRD results confirmed the formation of pure Y-type hexagonal ferrites at 1200°C sintering temperatures. EDS analysis confirmed elemental compositions and SEM provided morphology of the materials. The dielectric properties were measured using Impedance analyzer. At normal frequencies, the x = 1.0 doped sample showed significant increase in dielectric value which came to be of the order of 2500. This might be attributed to electron hopping between Fe2+ and Fe3+ ions and hole hopping between Ni2+ and Ni3+ ions, which could enhance dielectric properties in ferrites under applied electric fields. Furthermore, electrons transferred between Fe2+/Fe3+ ions and holes transferred between Ni2+/Ni3+ ions explain the pronounced improvement in electrical properties observed for x = 1.0 samples.
