Authors: Zhao Yi , Kumar Rohit , Rakib Abdul
Published: September 2024

This paper presents memristive nano-devices that naturally emulate these diverse synaptic functions. These memristors operate in a non-filamentary, low-conductance mode, ensuring stable and energy-efficient performance. Designed as adaptable hardware synapses for bio-inspired deep neural networks (DNNs), they incorporate both long- and short-term synaptic responses, enabling meta-learning—the ability to refine learning strategies over time. When applied to a demanding reinforcement learning task in a dynamic environment, the bio-inspired DNN with memristive synapses reduced energy consumption by approximately two orders of magnitude compared to traditional GPU-based implementations. This demonstrates that memristive devices, by more closely mimicking synaptic behavior, can greatly expand the potential of neuromorphic computing while enhancing the efficiency and performance of artificial intelligence systems.

piezo line plate lumen side cap ring structure new design separable support lumen Side Cap Piezo Plate (b) (c) Prototype Endovascular catheterization plays a crucial role in treating various cardiovascular conditions such as aortic valve stenosis and coronary heart disease, with over 200 million catheters being used annually during these procedures [1]. The insertion of catheters into blood vessels inevitably creates friction between the catheter and vessel wall. This generated friction is one of the most significant sources of prevalent cardiovas- cular intervention complications such as arterial spasm, hematoma and vascular trauma [1], [2]. Despite its complications, frictional interaction remains critical for ensuring catheter stability, especially during cutting or puncturing operations which require significant forces. Thus, managing this frictional interaction is essential for ensuring optimal patient outcomes. We previously introduced the concept of a friction programmable catheter, equipped with discrete friction control modules along its shaft to toggle between high and low friction states on demand [3]. Here, we present an enhanced iteration of these friction control modules, addressing the limitations of the earlier design resulting in improved performance and miniaturization. Further- more, we report the results of our first sliding friction experiments conducted on ex-vivo porcine aortic tissue.

Intraventricular hemorrhage (IVH) is bleeding inside the ventricular system of the brain. IVH evacuation is performed to remove blood products and relieve pressure. However, the procedure is challenging as the neurosurgeon must insert an endoscope through the brain cortex into the ventricle, potentially damaging the surrounding tissue due to the tilting required for visualization beyond a straight trajectory. As shown in Fig 1, when bleeding occurs in the temporal horn of the lateral ventricle, Kaufman’s point entry is used to access the bleeding site with a limited working window[1]. Several continuum robots, capable of performing snake-like motions, have been developed for intraventric- ular neuroendoscopic procedures [2]. They aim to facili- tate multiple intraventricular operations through a single incision. These robots primarily utilize tendon-driven and concentric tube designs. However, their metallic and rigid structures make them unsuited for magnetic resonance imaging (MRI) and can damage brain tissue. Soft robotic manipulators with pneumatic actuation have gained significant interest in minimally invasive surgery over the past decade. This type of robot poses benefits such as compliance with the surrounding envi- ronments, and MRI compatibility. This paper considers designing a soft robotic manip- ulator with pneumatic actuation for blood evacuation in a patient with IVH using Kocher’s point entry (Fig 1). The advantages of employing this trajectory over the conventional Kaufman’s point are: i) it avoids damage to the frontal cortex, ii) eliminates cosmetic scars on the patient’s face, and iii) the same incision can be used to access the third ventricle via the foramen of monro [1]. Notable works on design optimization for continuum robots in neurosurgery include [3]–[5] which were for extensible concentric tube robots. This work presents a design optimization approach for an inex- tensible soft manipulator based on piecewise constant curvature kinematics using anatomical data from a group of 40 patients.

Published: September 2024

In wearable robotics, physical Human-Machine Interfaces (pHMIs) should be able to adapt to the continuous physiological changes of body parts in an active, ergonomic, and safe way, ensuring a stable and comfortable biomechanical coupling with the user [1]. This is particularly urgent in limb prostheses, where the pHMI is constituted by the socket. Indeed, traditional sockets are rigid and passive structures, causing significant discomforts and dermatological problems for patients, ultimately leading to device abandonment. Recent works indicate that 44% of upper limb amputees abandon their prostheses due to residual limb discomfort or pain, especially trans-humeral amputees [2]. In this work, a smart trans-humeral socket is proposed. It integrates soft pneumatic actuators, a sensorized prosthetic liner, a wearable control unit, and a mobile app to enable both open- and closed-loop adaptation to residual limb volume changes, over time.

Published: September 2024

Pedicle screw placement (PSP) is crucial for managing symptomatic spinal disorders, but its success hinges on accurate placement to avoid pedicle breaches and nerve damage. These breaches can occur in a concerning range of 1.1% to 29.0% of procedures [1]. The ball-tip technique is initially introduced by using a ball-shaped metal tip with a metal semi-flexible shaft. The use of a ball-tip feeler at various checkpoints could assist the surgeon in confirming pedicle wall integrity and re- planing the screw trajectory. While the smart ball-tip feeler improves surgical time and accuracy, it remains heavily reliant on surgeon experience. To tackle this problem, recent studies have explored various sensors to automatically detect the breach during the drilling procedure, such as drilling force or electri- cal impedance [2]. Preliminary results show promising potential but are limited by cost and complexity. An affordable, user-friendly, and highly accurate breach detection solution would be preferential. Inertial mea- surement units (IMUs) and load cells are cost-effective options. However, traditional data processing methods can be unreliable. Deep learning, with its ability to identify patterns in complex data, presents a promising alternative for robust breach detection in PSP. This paper proposes a low-cost, deep learning-based technique using the ball-tip feeler to provide breach alerts via audible beeps. The developed system evaluated its performance on synthetic phantoms.

Magnetically responsive soft materials are envisioned as the next-generation building block in a myriad of applications including in minimally invasive surgical procedures, soft orthoses, and smart textiles due to their untethered, compliant, safe, and lightweight nature [1]. However, constructing highly integrated magnetic fibers with extreme aspect ratios, that can be used as steerable catheters, endoscopes, or in medical textiles, remains a significant materials and processing challenge. Here, we present multi-material thermal drawing as a materials and processing platform to manufacture 10s of meters long, soft, ultra-stretchable, yet highly resilient magnetic fibers with a diameter as low as 300 μm. The preform-to-fiber thermal drawing of magnetically responsive soft composite materials enables the fabrica- 5 tionofmagneticfiberswithhighaspectratiosof10 and intricate internal multi-material architectures, resulting in diverse functionalities [2]. We fabricate soft magnetic fibers that can bend, twist, and be steered in several different directions, deliver drugs, and also be weaved into forming functional magnetic textiles [2]. Integrating in a single thin and soft fiber actuation with sensing, along with the ability to deliver optical and electrical signals or possess micro- fluidics attributes, represents a substantial breakthrough in applications like smart catheters and soft medical textiles [3]. We also introduce nanocomposite conductive layers together with magnetic fibers aiming to build highly integrated smart catheters, and medical textile systems that can extract shape-morphing information for the rehabilitation to damaged joints.

Over 2% of the adult population in the United States is currently managing heart failure [1]. One form of treatment is cardiac resynchronization therapy in the form of biventricular pacing, in which a pacemaker’s electrical lead is delivered into the coronary sinus (CS) by way of the right atrium (RA) (Fig 1 a), stimulating more efficient cardiac contraction [2]. However, difficulties in CS cannulation have been observed in up to a quarter of patients, owing to challenging anatomy, unstable lead positioning, and CS dissection [3], [4]. Ultimately, current methods of CS cannulation may expose patients to nearly thirty minutes of X-ray fluoroscopy [5]. Several factors make it challenging to navigate a catheter within the beating heart and precisely position a lead within a coronary venous target. Often, interventional catheters have limited degrees of freedom, and are relatively unstable due to high flexibility. Robotic systems have attempted to add degrees of freedom and increase sta- bility [6], but elastic instabilities and frictional losses may hinder their ability to reach distant targets. Alternatively, soft robots possess material compliance for safe contact with delicate anatomy, and fluidic actuation increases stability and dexterity for interaction with distant targets. This study explores the development and validation of a soft robotic system for CS lead placement, building upon previous works by the authors [7], [8].

Published: September 2024

Cleft palate repair is a technically challenging procedure requiring delicate tissue handling and precision. In a pre- vious study, [1] our group demonstrated the advantages of using a surgical robot over traditional instruments in cleft palate repair. The 8 mm wrist was considered superior due to its more space-efficient articulation. However, the 8 mm diameter instruments are too large for the infant oral cavity. We have thus developed a novel 3 mm diameter pin-jointed wrist with a unique cable-guide channel and CAM mechanism to ensure more compact wrist articulation with a lower profile for this workspace [2]. Additionally, the tool profiles were optimized for infant cleft palate repair and trans-oral robotic surgery (TORS). The following study investigates the use of these 3 mm tools to perform knot-tying within the confines of the infant oral cavity using a high-fidelity cleft palate simulator. Their performance was compared to the 8 mm da Vinci EndoWrist instruments to determine the advantages of using these smaller tools.

Open Spina Bifida (OSB) is a neural tube defect where a section of the spinal cord develops outside the back of the fetus in the form of a lesion. A successful repair involves the dissection of the spinal cord from its’ surrounding lesion and then suturing the lesion wound to close. Research on this procedure is currently focused on minimally invasive robotic approaches. Suturing was found to be the more difficult and time intensive of the two tasks in the repair[1]. For a robotic approach, the tool ports into the uterus must be minimized to at least 3mm to reduce the likelihood of maternal complications [2]. A novel 2.8mm diameter tool and suturing technique has been proposed by Amanov and Ertop et al. for prostate surgery [3], [4]. In comparison, our tool is designed for a traditional suturing technique and timing results are provided. For this minimally invasive robotic task, we improve the latest 2mm diameter continuum tendon-driven wrist surgical tool design of Francis et al. [5] to improve gripper responsiveness, implement a numerical inverse kinematics solver integrated with a teleoperation controller, and show suturing feasibility through timed trials to support in-utero OSB repair.

Published: September 2024

Cardiovascular diseases, including Abdominal Aortic Aneurysms (AAA), are a major global health concern, causing millions of deaths annually [1]. The standard treatment for AAA involves minimally invasive endovas- cular surgery, inserting catheters and guidewires through the femoral artery to the target lesion, guided by X- ray Fluoroscopy. Challenges in this procedure include difficulty in manipulating the catheter tip, increased risk of vessel dissection, and reliance on surgeon skills [2]. Robotic platforms, like CathBot developed at Imperial College London, aim to enhance traditional surgery by providing remote manipulation of endovascular instru- ments, improving accuracy and repeatability [3]. Despite advancements, preventing inadvertent contact between instruments and vasculature remains a challenge. Our work addresses these limitations with a threefold con- tribution: (1) Development of a surgical scene sim- ulator that aesthetically replicates deformable tissue- instrument interaction, (2) Integration of such simulator with augmented reality (AR) technology and Cathbot, thus introducing the first steps towards a novel guidance system for endovascular navigation that, at this stage of development, could be used by clinicians as a training tool, and (3) Experimentation of the proposed system with users that have no prior experience with AR in guiding the instrument navigation.

Published: September 2024

Atrial fibrillation is the most prevalent form of persistent cardiac arrhythmia, causing uncoordinated heart beating, due to faulty electrical conductivity of the myocardium [1]. Cardiac ablation is a minimally-invasive procedure aiming at ablating the internal atrial walls to restore healthy electrical conduction. A transseptal sheath is positioned across from the right to left atrium, through a small puncture in the septum, reached from the femoral vein through the inferior vena cava (see Fig. 1). The ablating catheter is inserted through the sheath and used to ablate around the pulmonary veins. Robotic ablation procedures have the potential of cre- ating more uniform lesions, reducing operator fatigue and extending catheter reach. Magnetic actuation has attracted particular attention [2], since it can stabilize contact between the catheter tip and the wall of the beating heart - via magnetic attraction. However, it often requires large-scale actuation units, which are hard to integrate with the clinical workflow. This work introduces a novel magnetic navigation sys- tem for cardiac ablation (see Fig. 1), formed from two key elements: a magnetic ablation catheter [3] consisting of a chain of spherical permanent magnets (ball chain); and an actuation system comprised of two permanent magnets undergoing pure rotation. These two elements enable design of actuation units of reduced size: the large magnetic content of the ball chain allows use of smaller actuation magnets and pure rotation of the actuation magnets permits the use of a compact cart- based system. In our experiments, with a scaled version of the proposed platform (see Fig. 2), we demonstrate that pure rotation of the actuating magnet is sufficient for navigating around the pulmonary veins. Catheter control using a joystick is compared with manual operation of a standard ablation catheter. During learning, a novice can perform navigation tasks 1.6 times faster than with a manual catheter. Once proficient, an operator can navigate hard- to-reach areas 21% faster using the robot.

According to the 2020 Guidelines of the European Soci- ety of Cardiology, Atrial Fibrillation (AF) is recognized as the most prevalent cardiac arrhythmia, impacting approximately 2% to 4% of adults [1]. AF reduces left atrium contractility, increasing stroke risk fivefold. The percentage of strokes attributed to AF ranges from 1.5% at ages 50-59 to 23.5% at ages 80-89 [2]. Over 90% of left atrial thrombi associated with stroke originate from the Left Atrial Appendage (LAA). In recent decades, catheter-based procedures for mechanical Left Atrial Appendage Closure (LAAC) have emerged as a valid al- ternative to traditional long-term anticoagulation therapy for stroke prevention in AF patients. In the procedure, an occluder device is carried by a delivery sheath from the femoral vein to the left atrium, and it is implanted in the LAA. However, traditional LAAC procedures face sig- nificant challenges, including suboptimal device delivery and post-implantation peri-device leaks [3]. Commercial sheaths are passive and feature a pre-curved tip, thus limiting their adaptability to various LAA locations. We are proposing an innovative steerable sheath for LAAC which integrates a multi-Degree of Freedom (DOF) tendon-driven Nitinol tip actuated by a motor- ized system. The tip design provides tailored stiffness, independent proximal and distal segment bending, and fine control thanks to Nitinol’s superelasticity. These features aim to enhance co-axial alignment of the closure device with the LAA, facilitating a precise and effective implantation.

The responsibility of learning and skill development of individuals of the society has been given to the schools and institutions of higher education. Teachers are making efforts for providing education to students on the basis of pre-decided objectives. Examination plays a major role in the process of education, where the level of students learning required to measure. Schools and higher education institutions are following marking and grading system in examination process. This paper focuses on use of grading system in examination. After observations of weakness and side effects of marking system, different committees and commissions had recommended for use of grading system. Grading was observed more reliable than marking limited point (five to ten) in grading system is more suitable for assessment of students instead of 101 point scale in marking. Marking system leads to poor academic achievement, whereas grading system provides less stress and higher academic achievement. In the technological era, the grading system might be utilized to provide grades, feedback and analysis of students through Artificial Intelligence and gamification. On background of NEP 2020 UGC also communicated about grading and credit system and even formulated ‘National Credit Framework’. The cautious use of grading system will be more appropriate to teachers for assessment and to students for learning achievements.

G. E. Moore: 'Good' as a means and an end
Authors: Ranjan Rajanee
Published: September 2024

According to Moore, moral questions are often asked in two meanings, such as - 'What is a person's duty in these circumstances?' or "Is it right to do this?" or what should we strive for? Analysis of these questions is possible but any of them can be answered only by keeping in mind 'good in itself' and causal judgment - "A correct answer to any of them involves both judgements of what is good in itself and casual judgements" If we pay attention to intrinsic values and actions in the context of right and duty, this will become clear. If it is said that this action is the best, it means that this action along with its consequences has more intrinsic value than other actions.
Abstract in Hindi Language:

Authors: Iskandar Yelita Anggiane , Purba Niko Andri
Published: September 2024

PT Crieta Logistics ships goods in containers. In carrying out its business, the company often experiences lost sales which are caused by the unavailability of containers so that the orders can be fulfilled. From January to July 2022, PT Crieta Logistics experienced lost sales of 21, 9, 12, 34, 19, 4 and 2 TEUs respectively. Therefore, in this study forecasting the number of requests for containers at PT Crieta Logistics conducted to make decisions related to handling demand for containers in the coming period. This forecasting result served as a basic input to establish policies of container availability, such as whether to reorganize contracts with vendors or others. The forecasting is done using 3 methods, namely linear, quadratic, and exponential regression with historical data of 2 years from July 2020 to July 2022. In determining the most accurate forecasting method, the error value is calculated using the mean absolute percentage error (MAPE) method. In the linear regression method, the MAPE value is 9.5%, while in the quadratic method, the MAPE value is 9%, and in the exponential method, the MAPE value is 9.2%. The quadratic method was chosen as the method suitably used in forecasting the next 12 periods because it has the smallest MAPE value. Forecasting demand using the quadratic method produces 12,631 units of containers for the next 12 periods, from August 2022 - July 2023.

The Utility of Swords in Kandyan and Low- country Rituals
Authors: Amarathunga A. A. M. M. M. , Ranaweera W. V. P. H.
Published: September 2024

The sword, a distinctive weapon used in various countries, holds multiple utilities across cultures. Among them, rituals featuring swords are commonly found. Sword usage is also seen in folk rituals in Sri Lanka, which hold an important place in society. The main objective of this research was to explore how the sword, a destructive weapon with sharp edges, is integrated into local dance rituals in Sri Lanka. Accordingly, the ritualistic offerings and performances involving the sword, the utility, and the purpose of sword usage in folk rituals were examined. The research problem was whether the original intent and the functions of the sword are represented when it is employed as a ritualistic artifact or theatrical prop in rituals. Since the study followed an ethnographic research approach, it relied on field research in identifying the exact perspectives of the community regarding the usage of swords in rituals. Additionally, secondary sources located via library surveys were used to gain further insights to provide a nuanced analysis. Using Kandyan and Low-country traditions as the limitations of the study, direct and indirect observations of targeted rituals were done, and interviews were conducted with expert artisans. The data analysis revealed that in folk rituals, the sword serves multiple roles, i.e., as an ornament of deities; a ritualistic artifact; and theatrical prop. Moreover, evoking heroic sentiment and blessings are some of the purposes of using swords. However, some characters that enact devils also wield swords. It was also revealed that the use of the sword in the Kandyan tradition is relatively minimal compared to the low country tradition. This is because the prevalence of characters enacting gods and devils is high in Low country dance rituals. With the exceptions of ritual performances like Kadupaliya and Wina Kepeema, swords are not commonly used for sacrificial purposes. In conclusion, the use of swords in local dance rituals serves psychotherapeutic purposes in different ways and demonstrates its primary application in unique manners by symbolizing the original weapon.

Ibn Taymiyya (Makers of the Muslim World)
Authors: Hafiz Abdul Karim
Published: September 2024

The prevailing trend of studies on Ibn Taymiyya in the Western scholarship has always been segmented in nature. It may have begun with Henri Laoust, who examined the scholar's social and political theories in his Essai (1939). Following him is a plethora of studies covering various aspects of Ibn Taymiyya, ranging from examinations of his life and views to critical study upon his extensive works. Jon Hoover's Ibn Taymiyya, however, detaches away from the said approach. The author instead has offered a much wider assessment of every known aspect of Ibn Taymiyya's legacy. This could have come from the fact that this book is part of the Makers of the Muslim World series, where it focuses to bring scholarly series of biographical books concerning Muslim figures throughout history.
Smoking vs Socialism in Cuba
Authors: Sánchez González Efraín
Published: September 2024

The Cuban State, as the guarantor par excellence of the rights of citizens, has the responsibility conferred upon it by its own existence to promote and enforce the Fundamental Law of Socialism. This implies that it must provide the necessary conditions so that, given equal conditions, individuals have equal opportunities. Socioeconomic inequalities have a direct impact on social behavior due to their impact on the allocation and redistribution of resources. One of the forms of socioeconomic inequality that exists in Cuba today is the one that occurs due to smoking as a risk factor, since it leads to the fact that, under equal conditions other than smoking, smokers consume more goods and services than non-smokers. Given this situation, it is pertinent to describe some of the fundamental elements of contradiction between smoking as a risk factor and socialism in Cuba. Smoking is incompatible with Socialism in Cuba. There are four key elements that would contribute from government management to reduce the adverse effects of smoking in Cuba: eliminate the regulated distribution of cigarettes and tobacco, eliminate the subsidy for retail consumption of cigarettes and tobacco, market cigarettes and tobacco at market price and strengthen compliance with all non-tax measures restricting the consumption of cigarettes and tobacco.

Aim: The main aim of the study is to know the hemodynamic changes, level of sedation, and level of satisfaction of both the surgeon and patient when regional anesthesia is supplemented with sedatives. Methods: An extensive search of all materials related to the topic with keywords - Intraoperative sedation, Analgesia, Regional block, and Sedatives was carried out in the PubMed and Google Scholar Search engines. over 79 articles were identified on this topic including original research articles. Among these 15 articles were excluded as they did not match the field of our review and 21 articles were excluded as full articles were not available for review. Thus relevant research articles focusing on “Procedural sedation in regional Anaesthesia” published in the period 2000 – 2021 were included in the review. A total of 10 studies similar to the current study objectives were included in the study and analyzed. Conclusion: After reviewing the literature, we conclude that Propofol in combination with Ketamine given intravenously is a good substitute for procedural sedation along with regional anesthesia technique. When supplemented with regional anaesthesia, it is found to provide better hemodynamic stability intraoperatively and better surgeon and patient satisfaction.
