    Abstract Post-stroke gait is characterized by slow and asymmetrical hemiparetic gait. This is attributed to the paretic lower limb which has limited plantar propulsion. The most effective method to restore paretic limb function is constraint-induced movement therapy (CIMT), which promotes the usage of the paretic limb by restricting the movement of the unafflicted limb. However, due to the necessity of both lower limbs to perform gait, CIMT methods could not be directly applied for gait rehabilitation. In this study, we explore the feasibility of utilizing a knee scooter as a means to facilitate CIMT gait training. We hypothesize that if lower limb kinematics and muscle activation patterns during gait with a knee scooter match that of natural gait, the knee scooter could be utilized for CIMT gait training. We measured the lower-limb joint angles, plantar force,

    Abstract Finding the maximum independent set (MIS) of a large-size graph is a nondeterministic polynomial-time (NP)-complete problem not efficiently solvable with classical computations. Here, we present a set of quantum adiabatic computing data of Rydberg-atom experiments performed to solve the MIS problem of up to 141 atoms randomly arranged on the king lattice. A total of 582,916 events of Rydberg-atom measurements are collected for experimental MIS solutions of 733,853 different graphs. We provide the raw image data along with the entire binary determinations of the measured many-body ground states and the classified graph data, to offer bench-mark testing and advanced data-driven analyses for validation of the performance and system improvements of the Rydberg-atom approach.

    Abstract Adversarial robustness is considered a required property of deep neural networks. In this study, we discover that adversarially trained models might have significantly different characteristics in terms of margin and smoothness, even though they show similar robustness. Inspired by the observation, we investigate the effect of different regularizers and discover the negative effect of the smoothness regularizer on maximizing the margin. Based on the analyses, we propose a new method called bridged adversarial training that mitigates the negative effect by bridging the gap between clean and adversarial examples. We provide theoretical and empirical evidence that the proposed method provides stable and better robustness, especially for large perturbations.

    Abstract The risk management framework (RMF) applied by the United States combines the concepts of information security and risk management in the product development process. This includes the systematic structure of equipment, parts, other construction systems, facilities, and personnel, as well as the related security of cyberspace. This concept has been a concept that has been systematically applied for the completion of information security from the requirement planning stage to the destruction of the weapon system. The RMF, which should be reflected in the project of power enhancement to ensure the perfect performance of the weapons system that our military will use in the future, is unfamiliar to Republic of Korea Army (ROK). RMF is a step-level field that has not yet been based on detailed research and measures in any ROK military, such as the Army, Navy, and Air Force. However, the USFK, which is stationed in the Republic of Korea during peacetime, and the United States’ wartime reinforcement forces [Flexible Deterrence Option (FDO), Force Module Package (FMP), Time Phased Forces Deployment Data (TPFDD)], which are deployed at the request of the CFC Commander in the event of a crisis situation on the Korean peninsula and under the direction of the Joint Chiefs of Staff, are thoroughly prepared for cyber threats by applying the RMF procedure. Therefore, the military should also create and apply the corresponding procedures during combined and joint operations as soon as possible. This study aims to provide a direction for the development of a categorization system, which is the most basic and important step 1 system in the RMF process, and I hope that it will help in the implementation of the Korean Risk Management Framework (KRMF) that should be applied in the future.

    Abstract Purpose: This study aimed to investigate the failure of trochanteric fracture fixation according to the quality of fracture reduction on the anteroposterior (AP) and lateral views.
    Methods: Data from 340 female and 152 male patients ≥ 60 years of age who underwent intramedullary nailing for a trochanteric fracture between 2016 and 2020 were analysed retrospectively. The quality of fracture reduction was classified as type A, type E, and type I on the AP view and type N, type A, and type P on the lateral view according to the relative position of the proximal and distal fragments. The failure rate was evaluated and compared according to the quality of fracture reduction. The risk factors of the fixation failure were investigated by comparison of variables between patients with and without failure and by regression analysis.
    Results: Patients with poor reduction, type I and type P had higher failure rates. However, a statistically significant difference was found only for patients with poor reduction (type P) on the lateral view (p < 0.001). Patients with failure showed significantly higher rates of poor reduction on the lateral view and AO/OTA type A3 fractures. The regression analysis also showed that poor reduction on the lateral view (odds ratio [OR] 12.70; 95% confidence interval [CI] 4.0-40.6; p < 0.001) and AO/OTA type A3 fractures (OR 5.40; 95% CI 1.24-23.49, p = 0.025) were risk factors for failure.
    Conclusion: Poor reduction such as type P reduction was associated with failure after intramedullary nailing for trochanteric fractures. Surgeons should check the quality of fracture reduction carefully with the proper fluoroscopic view to prevent failure in geriatric patients with trochanteric fractures.

    Abstract Phytochrome B (phyB) expressed in the epidermis is sufficient to promote red light responses, including the inhibition of hypocotyl elongation and hypocotyl negative gravitropism. Nonetheless, the downstream mechanism of epidermal phyB in promoting light responses had been elusive. Here, we mutagenized the epidermis-specific phyB-expressing line (MLB) using ethyl methanesulfonate (EMS) and characterized a novel mutant allele of RRC1 (rrc1-689), which causes reduced epidermal phyB-mediated red light responses. The rrc1-689 mutation increases the alternative splicing of major clock gene transcripts, including PRR7 and TOC1, disrupting the rhythmic expression of the entire clock and clock-controlled genes. Combined with the result that MLB/prr7 exhibits the same red-hyposensitive phenotypes as MLB/rrc1-689, our data support that the circadian clock is required for the ability of epidermal phyB to promote light responses. We also found that, unlike phyB, RRC1 preferentially acts in the endodermis to maintain the circadian rhythm by suppressing the alternative splicing of core clock genes. Together, our results suggest that epidermal phyB requires RRC1 to promote light responses by activating the circadian rhythm in Arabidopsis thaliana.

    Abstract Deep learning is vulnerable to adversarial examples. Many defenses based on randomized neural networks have been proposed to solve the problem, but fail to achieve robustness against attacks using proxy gradients such as the Expectation over Transformation (EOT) attack. We investigate the effect of the adversarial attacks using proxy gradients on randomized neural networks and demonstrate that it highly relies on the directional distribution of the loss gradients of the randomized neural network. We show in particular that proxy gradients are less effective when the gradients are more scattered. To this end, we propose Gradient Diversity (GradDiv) regularizations that minimize the concentration of the gradients to build a robust randomized neural network. Our experiments on MNIST, CIFAR10, and STL10 show that our proposed GradDiv regularizations improve the adversarial robustness of randomized neural networks against a variety of state-of-the-art attack methods. Moreover, our method efficiently reduces the transferability among sample models of randomized neural networks.

    Abstract CCAR2 (cell cycle and apoptosis regulator 2) is a multifaceted protein involved in cell survival and death following cytotoxic stress. However, little is known about the physiological functions of CCAR2 in regulating cell proliferation in the absence of external stimuli. The present study shows that CCAR2-deficient cells possess multilobulated nuclei, suggesting a defect in cell division. In particular, the duration of mitotic phase was perturbed. This disturbance of mitotic progression resulted from premature loss of cohesion with the centromere, and inactivation of the spindle assembly checkpoint during prometaphase and metaphase. It resulted in the formation of lagging chromosomes during anaphase, leading ultimately to the activation of the abscission checkpoint to halt cytokinesis. The CCAR2-dependent mitotic progression was related to spatiotemporal regulation of active Aurora B. In conclusion, the results suggest that CCAR2 governs mitotic events, including proper chromosome segregation and cytokinetic division, to maintain chromosomal stability.
