Mechanical Manipulators Research Articles

Англоязычные эвфемизмы как средство манипулирования в прессе

This study is devoted to the analysis of the manipulative potential of euphemisms in the texts of the English-language press. The purpose of the work is to consider euphemisms as one of the types of manipulators in a journalistic text, revealing their role in forming the desired reaction. The scientific novelty of the study lies in the fact that euphemisms are not studied in isolation, but in combination with other lexical units that form a whole text and create manipulation of the recipient’s consciousness. The author of the article shows how euphemisms in combination with other lexical means can influence the perception of information and form a certain point of view. The article proves that euphemisms are actively used by the authors of articles in the function of manipulation. This research can be useful not only for students of language courses, translators and teachers, but also for journalists, since understanding the mechanisms of manipulation will help them to create more objective materials, and readers will critically evaluate information received from various sources.

Research status and reflection of the mechanism of TCM manipulation in the treatment of cervical spondylosis under the background of multi-disciplinary intersection

The study of TCM manipulation's mechanism is the key scientific issue in the current manipulation research. It is the key and difficult point on the road of modernization and internationalization of Chinese orthopedics and traumatology. Meanwhile, it is also an important way to clarify systematically the scientific connotation of TCM manipulation. At present, our country is in an important period when multi-disciplinary intersection lead knowledge production, scientific innovation, and discipline development. The trend of cross-innovation between Chinese orthopedics and traumatology and other disciplines provides the carrier and method for the study of TCM manipulation's mechanism. Cervical spondylosis is the traditional dominant disease of Chinese orthopedics and traumatology. In recent years, many scholars have applied multi-disciplinary techniques and theories to explore the mechanism of TCM manipulation by focusing on the four dimensions of muscle, bone, blood vessel and nerve. The article takes the treatment of cervical spondylosis by TCM manipulation as the research entry point, and integrates the application status and implementation strategies of various techniques and theories under the background of multi-disciplinary intersection, which is conducive to the better combination, innovation and transformation of Chinese orthopedics and traumatology with other disciplines, and provides ideas and references for systematically clarifying the scientific connotation of TCM manipulation.

Adaptive wrapping with active elastic band-based gripper for stable in-hand manipulation

Achieving both compliant grasping and robust in-hand manipulation for a robotic hand is a challenging task, especially for fragile or irregularly shaped objects. Active surface grippers usually rely on non-stretchable belts and compliant finger mechanisms for adaptive manipulation and grasping, requiring complex tensioning mechanisms that increase mechanical complexity. This paper presents a novel design of an active elastic band-based gripper, that can achieve translation and rotation of grasped objects with passive adaptive wrapping and active conveyor motion. The design utilizes pre-tensioned elastic bands that function simultaneously as an adaptive grasping mechanism and an active surface, conforming to the shape of the object shape and providing evenly distributed gripping forces. The principles of grasping and manipulation, as well as the fabrication process of the gripper are presented in this work, and the kinematics and workspace of the gripper with cylindrical objects are analyzed. Based on experiments, the contact stiffness model of the elastic band finger with cylindrical objects was established. To evaluate the performance of the gripper, we carried out experiments on manipulation objects with different shapes and sizes, such as boiled eggs, and fruits. Experimental results illustrated the adaptable grasping and stable in-hand manipulation ability of the gripper.

Concurrent manipulation of competitive mechanisms to construct glutathione-stabilized gold nanocluster-based dual-channel molecular classifier for metal ions detection and information steganography

Understanding charge transport in metal ion-mediated glutathione-stabilized gold nanoclusters (GSH-Au NCs) has proved difficult due to the presence of various competitive mechanisms, such as electron transfer (ET) and aggregation induction effect (AIE). In this paper, we present a dual-channel fluorescence (FL) and second-order Rayleigh scattering (SRS) sensing method for high-throughput classification of metal ions, relying on the competition between ET and AIE using GSH-Au NCs. The SRS signals show significant enhancement when Pb2+, Ag+, Al3+, Cu2+, Fe3+, and Hg2+ are present, as a result of the aggregation of GSH-Au NCs. Notably, the fluorescence signal exhibits the opposite trend. The FL intensities of GSH-Au NCs are enhanced by Pb2+, Ag+, and Al3+ through the AIE mechanism, while they are quenched by Cu2+, Fe3+, and Hg2+, which is dominated by the ET mechanism. By employing principal component analysis and hierarchical cluster analysis, these signals are transformed into unique fingerprints and Euclidean distances, respectively, enabling successful distinction of six metal ions and their mixtures with a low detection limit of 30 nM. This new strategy has successfully addressed interference from impurities in the testing of real water samples, demonstrating its strong ability to detect multiple metal ions. Impressively, we have achieved molecular cryptosteganography, which involves encoding, storing, and concealing information by transforming the selective response of GSH-Au NCs to binary strings. This research is anticipated to advance utilization of nanomaterials in logic sensing and information safety, bridging the gap between molecular sensors and information systems.

Insight into the Manipulation Mechanism of Polymorphic Transformation by Polymers: A Case of Cimetidine.

Employing polymer additives is an effective strategy to realize the manipulation of polymorphic transformation. However, the manipulation mechanism is still not clear, which limit the precise selection of polymeric excipients and the development of pharmaceutical formulations. The solubility of cimetidine (CIM) in acetonitrile/water mixtures were measured. And the polymorphic transformation from CIM form A to form B with the addition of different polymers was monitored by Raman spectroscopy. Furthermore, the manipulation effect of polymers was determined based on the results of experiments and molecular simulations. The solubility of form A is consistently higher than that of form B, which indicate that form B is the thermodynamically stable form within the examined temperature range. The presence of polyvinylpyrrolidone (PVP) of a shorter chain length could have a stronger inhibitory effect on the phase transformation process of metastable form, whereas polyethylene glycol (PEG) had almost no impact. The nucleation kinetics experiments and molecular dynamic simulation results showed that only PVP molecules could significantly decrease the nucleation rate of CIM, due to the ability of reducing solute molecular diffusion and solute-solute molecular interaction. A combination of crystal growth rate measurements and calculations of the interaction energies between PVP and the crystal faces of CIM indicate that smaller molecular weight PVP can suppress crystal growth more effectively. PVP K16-18 has more impact on the stabilization of CIM form A and inhibition of the phase transformation process. The manipulation mechanism of polymer additives in the polymorphic transformation of CIM was proposed.

Label-Free Continuous Cell Sorting Using Optofluidic Chip.

In the field of biomedicine, efficiently and non-invasively isolating target cells has always been one of the core challenges. Optical fiber tweezers offer precise and non-invasive manipulation of cells within a medium and can be easily integrated with microfluidic systems. Therefore, this paper investigated the mechanism of cell manipulation using scattering force with optical fiber tweezers. We employed flat-ended single-mode fiber to drive and sort cells and derived the corresponding scattering force formula based on the T-matrix model. A single-mode optical tweezers system for cell sorting was developed, and an optofluidic experimental platform was constructed that effectively integrates the optical system with microfluidic chips. The chip, featuring an expanded cross-channel design, successfully achieved continuous separation of yeast cells (8~10 µm in diameter) and polystyrene microspheres (15~20 µm in diameter), with a sorting efficiency of up to 86% and maintaining viability in approximately 90% of the yeast cells. Compared to other sorting systems, this system does not require labeling and can achieve continuous sorting with cell viability at a lower cost of instrumentation.

Does Phage Therapy Need a Pan-Phage?

The emergence of multidrug-resistant bacteria is undoubtedly one of the most serious global health threats. One response to this threat that has been gaining momentum over the past decade is 'phage therapy'. According to this, lytic bacteriophages are used for the treatment of bacterial infections, either alone or in combination with antimicrobial agents. However, to ensure the efficacy and broad applicability of phage therapy, several challenges must be overcome. These challenges encompass the development of methods and strategies for the host range manipulation and bypass of the resistance mechanisms developed by pathogenic bacteria, as has been the case since the advent of antibiotics. As our knowledge and understanding of the interactions between phages and their hosts evolves, the key issue is to define the host range for each application. In this article, we discuss the factors that affect host range and how this determines the classification of phages into different categories of action. For each host range group, recent representative examples are provided, together with suggestions on how the different groups can be used to combat certain types of bacterial infections. The available methodologies for host range expansion, either through sequential adaptation to a new pathogen or through genetic engineering techniques, are also reviewed.

The rise of Candida auris, a multidrug-resistant fungal pathogen, across more than 40 countries, has signaled an alarming threat to global health due to its significant resistance to existing antifungal therapies. Characterized by its rapid spread and robust drug resistance, C. auris presents a critical challenge in managing infections, particularly in healthcare settings. With research on its biological traits and genetic basis of virulence and resistance still in the early stages, there is a pressing need for a concerted effort to understand and counteract this pathogen. This review synthesizes current knowledge on the epidemiology, biology, genetic manipulation, pathogenicity, diagnostics, and resistance mechanisms of C. auris, and discusses future directions in research and therapeutic development. By exploring the complexities surrounding C. auris, we aim to underscore the importance of advancing research to devise effective control and treatment strategies.

Acoustofluidic manipulation for submicron to nanoparticles.

Particles, ranging from submicron to nanometer scale, can be broadly categorized into biological and non-biological types. Submicron-to-nanoscale bioparticles include various bacteria, viruses, liposomes, and exosomes. Non-biological particles cover various inorganic, metallic, and carbon-based particles. The effective manipulation of these submicron to nanoparticles, including their separation, sorting, enrichment, assembly, trapping, and transport, is a fundamental requirement for different applications. Acoustofluidics, owing to their distinct advantages, have emerged as a potent tool for nanoparticle manipulation over the past decade. Although recent literature reviews have encapsulated the evolution of acoustofluidic technology, there is a paucity of reports specifically addressing the acoustical manipulation of submicron to nanoparticles. This article endeavors to provide a comprehensive study of this topic, delving into the principles, apparatus, and merits of acoustofluidic manipulation of submicron to nanoparticles, and discussing the state-of-the-art developments in this technology. The discourse commences with an introduction to the fundamental theory of acoustofluidic control and the forces involved in nanoparticle manipulation. Subsequently, the working mechanism of acoustofluidic manipulation of submicron to nanoparticles is dissected into two parts, dominated by the acoustic wave field and the acoustic streaming field. A critical analysis of the advantages and limitations of different acoustofluidic platforms in nanoparticles control is presented. The article concludes with a summary of the challenges acoustofluidics face in the realm of nanoparticle manipulation and analysis, and a forecast of future development prospects.

Flexible wavefront manipulation using exceptional points generated by non-interleaved metasurfaces

Precise modulation of the optical wavefront is the main way in which metasurfaces act, and the exceptional point (EP) topological phase provided by non-Hermitian metasurfaces offer an additional degree of freedom for the metasurface design. Here, we design an F-shaped non-interleaved metasurface whose unit cell consists of two basic resonators – a nanowire and a split ring resonator (SRR). By adjusting the strength and coupled-mode of these two resonators, the 2π phase accumulation enclosing the EP, the asymmetric transport properties, and the evolution of wavelength-dependent EP are observed. These properties allow for flexible wavefront manipulation in polarization, amplitude and wavelength dimensions. We simulate and demonstrate a spin-decoupled metasurface hologram, a dual-wavelength decoupled metasurface hologram, as well as a dual-wavelength metasurface for near-field nanoprinting and far-field holography. Non-Hermitian topological metasurfaces can be conveniently combined with other wavefront manipulation mechanisms, showing promising applications in the design of nanophotonic devices.

Advanced Real Time Bone Fracture Monitoring with Pain Control Mechanism

Bones provide structural aid to the frame, and bone fracture recuperation is crucial for regaining functionality and mobility. The boundaries of traditional external fixators in bone fracture remedy, characterized by a loss of actual-time monitoring and capability complications, necessitate a paradigm shift. To clear up this trouble, a clever fixator design imbued with the transformative energy of Aware, Sensing, Smart, and Active (ASSA) technology has been developed. This fixator transcends its passive role, evolving into a wise IoT gateway. It continuously gathers and analyses facts from numerous incorporated sensors, supplying real-time insights into the tricky dance of fracture healing. Its analytical prowess fosters computerized identification of vital activities and milestones within the affected person's recuperation journey, empowering well-timed interventions and knowledgeable scientific selection-making. Furthermore, the fixator vigilantly monitors patient compliance, making sure adherence to prescribed behaviours and nipping non-compliance in the bud. However, its innovation extends beyond mere monitoring. Embedded within its smart framework lies a modern pain manipulation mechanism powered through a thermoelectric generator (TEG).

Synergetic Manipulation Mechanism of Single-Atom M-N4 and M-OH (M = Mn, Fe, Co, Ni) Sites for Ozone Activation: Theoretical Prediction and Experimental Verification.

Carbon-based single-atom catalysts (SACs) have been gradually introduced in heterogeneous catalytic ozonation (HCO), but the interface mechanism of O3 activation on the catalyst surface is still ambiguous, especially the effect of a surface hydroxyl group (M-OH) at metal sites. Herein, we combined theoretical calculations with experimental verifications to comprehensively investigate the O3 activation mechanisms on a series of conventional SAC structures with N-doped nanocarbon substrates (MN4-NCs, where M = Mn, Fe, Co, Ni). The synergetic manipulation effect of the metal atom and M-OH on O3 activation pathways was paid particular attention. O3 tends to directly interact with the metal atom on MnN4-NC, FeN4-NC, and NiN4-NC catalysts, among which MnN4-NC has the best catalytic activity for its relatively lower activation energy barrier of O3 (0.62 eV) and more active surface-adsorbed oxygen species (Oads). On the CoN4-NC catalyst, direct interaction of O3 with the metal site is energetically infeasible, but O3 can be activated to generate Oads or HO2 species from direct or indirect participation of M-OH sites. The experimental results showed that 90.7 and 82.3% of total organic carbon (TOC) was removed within 40 min during catalytic ozonation of p-hydroxybenzoic acid with MnN4-NC and CoN4-NC catalysts, respectively. Phosphate quenching, catalyst characterization, and EPR measurement further supported the theoretical prediction. This contribution provides fundamental insights into the O3 activation mechanism on SACs, and the methods and ideals could be helpful for future studies of environmental catalysis.

Random broadband filters based on combination of metasurface and multilayer thin films for hyperspectral imaging

Metasurface based micro-spectrometer presents a promising avenue for achieving compact, lightweight, and cost-effective solutions for miniaturization of hyperspectral imaging systems. Nevertheless, this type of design encounter limitations primarily due to constrained manipulation mechanism of light field, resulting in high cross-correlation among transmission spectra and imperfect reconstructed images. In this paper, we propose and numerically demonstrate a micro-spectrometer based on metasurface combined with multilayer thin films, whose spectral response improves performance for application, i.e. achieving low spectral cross-correlation. Additionally, we incorporate particle swarm optimization with compressed sensing algorithm to optimize the proposed micro-spectrometer. This approach effectively reconstructs both narrowband and broadband hyperspectral signals with minimal error, achieving an impressive 2 nm spectral resolution. The simulation results of hyperspectral imaging demonstrated that the proposed methodology successfully reconstructs broadband hyperspectral images with an average spectral fidelity of 91.42%. This method holds significant potential for integrating into smartphones and other portable spectrometers, advancing the design of compact hyperspectral imaging systems.

Identification of Phytophthora cinnamomi CRN effectors and their roles in manipulating cell death during Persea americana infection

The oomycete Phytophthora cinnamomi is a devastating plant pathogen with a notably broad host range. It is the causal agent of Phytophthora root rot (PRR), arguably the most economically important yield-limiting disease in Persea americana (avocado). Despite this, our understanding of the mechanisms P. cinnamomi employs to infect and successfully colonize avocado remains limited, particularly regarding the pathogen’s ability to maintain its biotrophic and necrotrophic lifestyles during infection. The pathogen utilises a large repertoire of effector proteins which function in facilitating and establishing disease in susceptible host plants. Crinkling and necrosis effectors (CRN/Crinklers) are suspected to manipulate cell death to aid in maintenance of the pathogens biotrophic and necrotrophic lifestyles during different stages of infection. The current study identified 25 P. cinnamomi CRN effectors from the GKB4 genome using an HMM profile and assigned putative function to them as either cell death inducers or suppressors. Function was assigned to 10 PcinCRNs by analysing their RNA-seq expression profiles, relatedness to other functionally characterised Phytophthora CRNs and tertiary protein predictions. The full-length coding sequences for these PcinCRNs were confirmed by Sanger sequencing, six of which were found to have two divergent alleles. The presence of alleles indicates that the proteins encoded may perform contradicting functions in cell death manipulation, or function in different host plant species. Overall, this study provides a foundation for future research on P. cinnamomi infection and cell death manipulation mechanisms.

INVESTIGATION OF HYPERSURFACES THAT DETERMINE THE DIGGING FORCE OF SOIL WITH AN EXCAVATOR BUCKET ON THE MAXIMUM LOADS IN HYDRAULIC CYLINDERS

The problem of determining the forces acting on the rods of hydraulic cylinders when performing the operation of digging the soil with an excavator bucket with different depths and orientations of the output link when it moves along a horizontal trajectory is solved. For this purpose various excavator configurations are constructed according to the velocity vector and the generalized coordinates and forces acting on the hydraulic cylinder rods are recorded in the database. Based on the known digging resistance force, the forces acting in the direction of the hydraulic cylinder rods are calculated. Using the data obtained, an image of the hypersurface was made on the Radishchev drawing, reflecting the influence of the force value on the bucket hydraulic cylinder rod from the values of generalized coordinates for a given bucket orientation angle and a resistance force. An algorithm has been developed for calculating the values of forces on the rods of hydraulic cylinders for various positions of the excavator manipulator mechanism using the given nodal points of hypersurfaces based on point calculus. Analytical dependences are determined, which are used to check the possibility of ensuring the movement of the bucket with given conditions.

Force-position collaborative optimization of rope-driven snake manipulator for capturing non-cooperative space targets

With the rapid development of space activities, non-cooperative space targets increase swiftly, such as failed satellites and upper stages, threating normal spacecrafts seriously. As there are some problems in the capture process, such as excessive collision and fast tumbling of targets, manipulator with redundant Degrees of Freedom (DOFs) can be used to improve the compliance and therefore solve these problems. The Rope-Driven Snake Manipulator (RDSM) is a combination of hyper-redundant DOFs and better compliance, and therefore it is suitable for capturing mission. In this paper, a snake manipulator mechanism is designed, and the complete kinematic model and system dynamic model considering RDSM, target and contact is established. Then, to obtain the configuration of joint with hyper-redundant DOFs, an improved motion dexterity index is proposed as the joint motion optimization target. Besides, the force-position collaborative optimization index is designed to adjust active stiffness, and the impedance control method based on the modified index is used to capture the space target. Finally, the proposed force-position collaborative optimization method is verified by virtual prototype co-simulation. The results demonstrate that based on the proposed method, the collision force is reduced by about 25% compared to normal impedance control, showing higher safety.

PROBLEMS AND PRIORITIES FOR PREVENTING UNDECLARED LABOUR IN UKRAINE

The purpose of the article is to identify the scale of undeclared labour in Ukraine and to study the problems, principles and prospects of its prevention in unstable socio-economic conditions. Methodology. In line with the EU and ILO methodology, the State Labour Service of Ukraine interprets undeclared labour as legal paid activity that is not fully or partially registered in accordance with the law. Results. Undeclared work plays an important role in the practice of business management and competitiveness stimulation in countries with industrial, neo-industrial and post-industrial economies, which has been developed almost since the middle of the 20th century. The paper proves that undeclared work is a broader concept that includes legalised (both official and manipulative) as well as shadowy mechanisms of its occurrence and functioning. Given the problematic performance by the State Labour Service of Ukraine of its inspection and sanctioning powers, as well as the widespread use of non-standard labour relations (with mediation in the performance of employer functions, outsourcing of auxiliary, service and some specialised personnel to companies), tariff-free remuneration systems encourage numerous manipulations in the area of labour declaration and decent wages. The source of problems with the spread of remuneration systems based on an assessment of the complexity of the work performed and the qualifications of employees, as well as with ensuring decent working conditions for agency (loan, temporary) workers, is the unclear legislative regulation of these systems. Practical implications. The priorities for preventing undeclared labour in Ukraine are: a consistent increase in the share of wages in the structure of production costs; strengthening cross-control over the fulfilment of obligations to pay the minimum wage under the tariff-free and hourly wage systems; and the introduction of a sound methodology for harmonising the minimum wage, the subsistence minimum and other basic social standards linked to them. Value/Оriginality. The expediency of identifying institutionalised and manipulative mechanisms of undeclared labour, their formal and illegal bases is confirmed by the classification of the main forms of undeclared labour used by the EU, ILO and the State Labour Service of Ukraine; this approach will increase the complexity and effectiveness of systemic measures to regulate it (control, mitigation, prevention).

Strategy of Russian Military Cooperation with the Countries of the Arab Region

The article undertakes an analysis of the prospective domains of Russian military collaboration with Arab countries against the backdrop of geopolitical uncertainties. Despite maintaining its position as the second-largest arms exporter globally, Russia has experienced a proportional decline in its share of the global arms market. Nevertheless, a discernible uptick in the trade volume of conventional weaponry, coupled with cyclical enhancements in the tactical and technical attributes of military assets, reflects positive momentum in this sector. Amid prevailing external constraints and a noticeable scarcity of contemporary Russian weaponry in burgeoning segments of the arms market, Russia necessitates resolute and equitable measures to uphold and fortify collaborative ties with partner nations. Within this context, particular emphasis is placed on Russia's strategic military cooperation with Arab states, given the region's status as a focal point of geopolitical interests for major economies and a primary destination for arms imports.The article scrutinizes Russia's competitive standing in the arms and military equipment markets of the Arab world, acknowledging the region's significance as a pivotal importer of such goods. Employing a multifaceted evaluation encompassing absolute and relative statistical metrics and derived indices, the study assesses the region's role in global arms procurement. Moreover, it offers an appraisal of the existing state and potential avenues for enhancing the efficacy of the Russian-Arab military-technical collaboration framework. The discourse delves into the transformative prospects of this partnership within the framework of networkcentric warfare concepts. Furthermore, the article elucidates the principal risks inherent in military cooperation among nations at present, highlighting concerns regarding the possible manipulation of military-technical cooperation mechanisms to serve as leverage in furthering the geopolitical aspirations of specific stakeholders.In conclusion, the study posits forward-looking trajectories for bolstering bilateral relations, both sectorally and geographically. These include initiatives such as expanding licensing, leasing, offset transactions, and technology transfer initiatives; advocating for fifth-generation fighter aircraft and long-range radar detection and control systems, leveraging Industry 4.0 technologies; and prioritizing the training of foreign specialists.

Electric-field control of nonvolatile resistance state of perpendicular magnetic tunnel junction via magnetoelectric coupling.

Magnetic tunnel junctions (MTJs) are the core elements of spintronic devices. Now, the mainstream writing operation of MTJs mainly relies on electric current with high energy dissipation, which can be greatly reduced if an electric field is used instead. In this regard, strain-mediated multiferroic heterostructure composed of MTJ and ferroelectrics are promising with the advantages of room temperature and magnetic field-free as already demonstrated by MTJ with in-plane magnetic anisotropy. However, there is no such report on the perpendicular MTJs (p-MTJs), which have been commercialized. Here, we investigate electric-field control of resistance state of MgO-based p-MTJs in multiferroic heterostructures. A remarkable and nonvolatile manipulation of resistance is demonstrated at room temperature without magnetic field assistance. Through various characterizations and micromagnetic simulation, the manipulation mechanism is uncovered. Our work provides an effective avenue for manipulating p-MTJ resistance by electric fields and is notable for high density and ultralow power spintronic devices.
