Problematic issues arising in the field of state registration of acts of civil status

State registration of civil status acts is one of the forms of public services in the field of administrative law. The public service orientation of executive authorities and local self-government bodies is a priority in the decentralization processes which are taking place in Ukraine today. The focus of the local government reform is on people, and one of the important factors of their comfort is the provision of quality administrative services. Every day, children are born in Ukraine, some get married, some get divorced, and some die. Despite all the difficulties that exist today, the service of state registration of civil status acts is the most popular among Ukrainian citizens. The armed aggression of the Russian Federation against Ukraine has made many adjustments to our everyday life and the life of the country as a whole. Despite all the challenges, the legislator is trying to facilitate bureaucratic procedures, including in the field of civil registration. The latest technologies are being actively introduced, and amendments and additions are being made to the legislation in the field of state civil registration. Despite the significant progress in civil registration legislation, some difficulties arise in practice, especially in situations of state registration of marriage or divorce when one of the spouses is a military officer, or if one of the spouses is abroad, or in the area of active hostilities, or in the temporarily occupied territories of Ukraine. Regarding the temporarily occupied territories, unfortunately, during the 10 years of armed conflict, Ukraine has not been able to simplify the procedure for legitimizing civil status acts issued in the temporarily occupied territories of Ukraine. Therefore, Ukrainian citizens must go to court to recognize facts that have legal significance. Therefore, it is necessary for the legislator to resolve the problematic issues related to state registration of civil status acts.

Redundant non-serial compound manipulator kinematics and dynamics

Redundant non-serial compound manipulators with closed kinematic and actuator loops that enhance precision control and load carrying capacity are treated. Generalized coordinates and associated holonomic constraints that account for kinematic and actuator closed loops and singularity free representation of orientation of spatial manipulator bodies augment input and output coordinates in the kinematic formulation. Disjoint assembly components and path connected singularity free assembly components of manipulator configuration space are defined, in which manipulator kinematics and dynamics can be reliably carried out. A set-valued inverse kinematic configuration mapping is derived, with which compound redundant manipulators are shown to be locally cyclic. A new system of manipulator operational coordinates comprised of output and self-motion coordinates are defined and shown to be equivalent to input coordinates in representation of manipulator kinematics and dynamics. Well-posed ordinary differential equations of manipulator dynamics in both input and operational coordinates are presented that require no ad-hoc derivation. Five model manipulators illustrate applications involved and theoretical methods presented.

Athletes' Action Recognition and Posture Estimation Algorithm Based on Image Processing Technology

A posture estimation algorithm based on image processing technology involves analyzing images or video frames to determine the position and orientation of human bodies or specific body parts. This process typically begins with detecting key points or landmarks on the body, such as joints or anatomical features. This paper presents a novel approach for athletes' action recognition and posture estimation using image processing technology, specifically focusing on the Contour Mapping Multivariant Recognition and Estimation (CMMRE) algorithm. The primary objective is to develop a robust system capable of accurately identifying human actions and estimating postures from visual data, with potential applications in sports analysis, surveillance, and human-computer interaction. The CMMRE algorithm employs advanced techniques for contour mapping, feature extraction, and prediction, leveraging deep learning methodologies to analyze and interpret visual information effectively. Through a series of experiments and simulations, the algorithm's performance is evaluated, showcasing its ability to achieve high accuracy in action recognition tasks across various scenarios. The results highlight the algorithm's strengths in accurately predicting actions and estimating postures, while also identifying areas for improvement. The algorithm achieved an average accuracy of 95% in recognizing walking and running actions, and 80% in identifying jumping actions. The results highlight the algorithm's strengths in accurately predicting actions and estimating postures, while also identifying areas for improvement.

Intimate Outer Space: Towards a Politics of Gravity, Waste, and the Spatial Orientation of Bodies

Examining the feat of maintaining life in orbit draws a sharp focus to the relationship between the human body and its environment, the porous and circulatory matter that blurs any boundaries between habitat and habitant. These intimate, engineered spaces evoke a microcosm of urgent planetary concerns surrounding air and water resources, and waste capture, storage, and elimination. This paper explores NASA’s management of biological operations and discharge wastes in low gravity environments. Without strong gravitational fields, liquids coalesce at the location they are created, instead of flowing down and away. Such excesses disrupt the orderly engineered environments and minutely monitored bodies of these techno-scientific endeavors. Analyzing astronaut tears, space gynecology, zero-g surgery, and NASA’s “Space Poop Challenge” through feminist queer and disability theory, new materialist, and discard studies lenses, this paper seeks to refigure the deeply entangled relationships between fleshy bodies and planetary bodies, biomass and geomass, and prompt new discussions of gravity politics.

Effects of the political configuration of local governments on subjective well-being

ABSTRACT Determining what makes a person happy is an extremely complicated task. The objective of this article is to identify the effects of the composition and orientation of governance bodies in municipalities on individual subjective well-being. We connect the data from a large Spanish welfare survey to municipal data covering the aforementioned dimensions of political configuration. Unlike previous country-level studies, we find no significant effects of political orientation when applied to municipal data. In contrast, political alternation emerges as a relevant driver of subjective well-being, especially when corrupt local governments are replaced. Furthermore, the fragmentation in the Spanish political landscape after the 2015 elections improved the level of political competition, which, in turn, exerted a positive effect on subjective well-being.

Δ3-tubulin impairs mitotic spindle morphology and increases nuclear size in pancreatic cancer cells.

Cancer cell proliferation is affected by post-translational modifications of tubulin. Especially, overexpression or depletion of enzymes for modifications on thetubulin C-terminal region perturbs dynamic instability of thespindle body. Those modifications include processing of C-terminal amino acids of α-tubulin; detyrosination, and a removal of penultimate glutamic acid (Δ2). We previously found a further removal of the third last glutamic acid, which generates so-called Δ3-tubulin. The effects of Δ3-tubulin on spindle integrities and cell proliferation remain to be elucidated. In this study, we investigated theimpacts of forced expression of Δ3-tubulin on the structure of spindle bodies and cell division in a pancreatic cancer cell line, PANC-1. Overexpression of HA-tagged Δ3-tubulin impaired the morphology and orientation of spindle bodies during cell division in PANC-1 cells. In particular, spindle bending was most significantly increased. Expression of EGFP-tagged Δ3-tubulin driven by the endogenous promoter of human TUBA1B also deformed and misoriented spindle bodies. Spindle bending and condensation defects were significantly observed by EGFP-Δ3-tubulin expression. Furthermore, EGFP-Δ3-tubulin expression increased the nuclear size in a dose-dependent manner of EGFP-Δ3-tubulin expression. The expression of EGFP-Δ3-tubulin tended to slow down cell proliferation. Taken together, our results demonstrate that Δ3-tubulin affects the spindle integrity and cell division.

Beyond the Pastoral Paradise: Orienting Black and Muslim People in British Rural Space

While there is an increasing number of Black and Muslim stories in urban settings, cultural imaginations of the British rural as linked to whiteness are pervasive. Despite there being a long-established presence of Black and Muslim people in British rural areas, their bodies are excluded or made to disappear to make the rural and, by extension, the nation (supposedly) safe. Drawing on Sara Ahmed’s notion of white habit worlds, this article explores the specific ways in which popular imaginations of rural spaces in the UK orient Black and Muslim bodies in relation to rurality. I will argue that whiteness as the racialisation of the pastoral form is closely imbricated with the Christian pastoral notion of Eden by close reading season five of the TV crime drama Shetland, the feature film Four Lions (2010) and the documentary Arcadia (2017). By asking how these configure British rural space through their orientation of Black and Muslim bodies and how they contest or reinforce the (lack of) belonging of bodies considered ‘non-white’/‘non-Christian’ in rural spaces, I inquire how these productions complement each other in what they have to say about the presence of Black and Muslim bodies in British rural space and how this relates to wider debates about immigration and national identity.

Early Iron Age Mound Near the Village Malynivtsi in Podillia

The purpose of the research paper is to introduce the materials of mound 1 near the village of Malynivtsi in the Middle Dniester region to scientific circulation. It is crucial to characterize its funeral rites, as well as to attribute the inventory complex. Burials are included in the list of synchronous antiquities of the region. The social attribution of the persons buried there is conducted.
 The scientific novelty of the work is in the general characteristic of the Early Iron Age complex from Podillia. Since its unique characteristic is the presence of both pre-Scythian and Scythian features in the rites, Malynivtsi burial complex is an important source for studying the evolution of the Early Scythian funeral rites in the Middle Dniester region, because most of the burial mounds in the region are associated with the somewhat later Kelermesskaia period.
 Conclusions. Mound 1 near Malynivtsi contained several burials performed according to both inhumation and cremation rites. Analogies to them can be found in the Middle Dniester region and they are associated with both pre-Scythian and Scythian times. The pre-Scythian features include the presence of a group of graves under one mound, burial in a cist, group burials are more common, and the peculiar positioning of the dead in one tomb with their heads in different directions. The northwestern orientation of bodies also prevails in the pre-Scythian period and could be found in most necropolises of that time. At the same time, a number of features already have parallels in the Scythian times: the topography of the necropolis on the watershed, and the burning down of the wooden constructions of the tomb. The inventory complex contains mainly handmade pottery. Tulip-shaped vessels are characteristic of the pre-Scythian period. Pots with a roller on the rim and body, or only on the rim, existed both in the pre-Scythian and Scythian times. However, the first type is not yet known among the burials of the Western Podillia group of the Scythian period. Thus, according to the combination of features of the funeral rite and inventory, Mound 1 near the village of Malynivtsi can be attributed to the turn of the Pre-Scythian and Scythian periods.

The climate adaptive characteristics of urban inside/outside water bodies based on their cooling effect in Poyang and Dongting lake regions, China

Most publications have focused on the cooling effect of urban inside water bodies. However, the climate adaptive characteristics of urban inside/outside water bodies is seldom studied. In this paper, three types of water bodies, i.e., urban inside water bodies, urban outside discrete water bodies and large water bodies are identified according to their relative spatial relationships with built-up areas. The climate adaptive landscape characteristics of water bodies are analyzed based on water bodies’ cooling effect (WCE) inside and outside cities in the Poyang Lake and Dongting Lake regions. Seventy-three Landsat TM/OLI/TIRS images acquired from 1989 to 2019 are employed. Landscape scale characteristics of urban inside/outside water bodies are described by area, water depth, perimeter to area ratio (PARA) and distance-weighted area index (DWAI). Three temperature-related parameters are calculated to estimate the WCE in different conditions. Climate adaptive characteristics of water bodies inside/outside cities are determined by correlation and regression analysis. Results show that: 1) The long river shape, depth, orientation and fluidity of urban inside water bodies are benefit to enhance their cooling effect; 2) the distance of urban outside water bodies from built-up areas are positive correlated with their cooling effect; 3) the optimal acreage of large water bodies are >2500 km2 and 1111–1287.5 km2 for climate adaption of Poyang Lake and Dongting Lake, respectively. Simultaneously, the WCE of urban outside large water bodies is related with human activities and climate conditions. The results of our study provide a significant contribution to blue-space planning in cities, and provide insights into actionable climate adaption planning in inland large lake areas.

Analysis of citizens’ participation in the management of independent budget of local self-government

Involvement of citizens in the budget management of local self-government remains an open question due to the lack of a clear mechanism for their participation in this process, but without which it is impossible to carry out reforms to decentralize public administration. The purpose of this study is to identify the main problems and identify tools for involving citizens in the process of self-government by the budget of rural territories. The article presents the results of a sociological survey that allowed us to determine the degree of citizens’ participation in the management of the budget of local self-government using two main dimensions: the assessment of citizens’ involvement and the assessment of citizens’ participation in the management of the budget of the fourth level. The novelty of the expected results consists in the development of recommendations to ensure the flexibility of the mechanism of interaction between the state body and the population, aimed at increasing the customer orientation of state bodies and stimulating the activities of both public organizations and individual citizens. This is due to the fact that it is necessary to eliminate formalism when holding meetings of heads of state bodies with the population, business and public associations.

FRACTURED TECTONICS OF CHROMITITES OF THE MAIN SARANOVSKOYE DEPOSIT (PERM KRAI)

The Main Saranovskoe deposit is one of the largest chrome deposits in Russia. The chrome ore bodies are localized in the ultramafites of the Northern Saranovsky massif which has been studied since 1907. The research revealed that the massif is similar to the Bushveld stratiform complex. Unlike other layered plutons, the Northern Saranovsky massif has a large amount of chrome ore bodies as compared to ultramafic host rocks. As many studies have shown, the chromitites of the Main Saranovskoe deposit are severely tectonized. The strike and dip of the ore bodies is complicated by numerous faults. These observations imply that the massif is a fragment of a large stratified pluton intruded into the Proterozoic metasedimentary unit. The fracturing reflects the massif intrusion conditions and provides new petrogenetic information on the relevance of our study of the tectonic fractures of the Saranovsky massif. Studies have been made on the fracture and furrow displacement orientations along the planes in the main ore bodies: western, central and eastern, within the two parts of the deposit. The local stress tensor has been reconstructed using the Angelier method in the Win-Tensor program. It has been stated that the chromitites studied contain 3–4 main fracture systems whose orientation varies together with the orientation of the ore bodies. The main compressive stress axis is oriented subvertically both in the central and southern parts of the deposit, and the main tensile stress axis forms an acute angle with the ore body contacts in the center of the deposit and is oriented subperpendicular to them in the southern part. It has been concluded that fracturing of the chrome ore bodies in the Main Saranskoe deposit took place during the massif motion into the upper crustal horizons with the subvertical orientation of the ore bodies remained unchanged. This casts doubts on the probability of formation of the Northern Saransky massif as a result of gravity differentiation of magmatic melt, since in this case the ore bodies should have undergone a vertical turn which is not exhibited by their fracturing.

Sense, Orientation, and World Creation

Abstract This article stages a dialogue between Jean-Luc Nancy’s postphenomenology and Sara Ahmed’s queer phenomenology to examine the conditions, ethos, and politics of world creation as well as the habits, obstacles, and inequalities that resist it. It argues that Nancy’s understanding of sense as the event of the mutual exposure of bodies reveals what exceeds dominant worldviews, how bodies extend the world beyond prevailing spatializations, but that it does not sufficiently examine what prevents us from sensing that event as a call to world creation. Conversely, Ahmed analyzes how the spatial orientation of bodies restricts exposure, causes uneven access to the world, and suppresses Nancean sense. Her account of disorientation illuminates how we could experience the world as ungrounded and susceptible to creation but struggles to explain what would enable the sharing of this event so that it does not reconfirm the dominant orientations of whiteness and heterosexuality. Reframing disorientation in terms of Nancy’s relational ontology and its spatial conception of justice rethinks the nonalignment of bodies and spaces as freeing the circulation of sense so that alternative worlds could appear. In this way, disorientation can be read as potentially opening the passage from injustice to justice, from orientation to creation.

Ependyma: a new target for autoantibodies in neuromyelitis optica?

Neuromyelitis optica (NMO) is an autoimmune demyelinating disease of the central nervous system characterized by the presence of autoantibodies (called NMO-IgG) targeting aquaporin-4. Aquaporin-4 is expressed at the perivascular foot processes of astrocytes, in the glia limitans, but also at the ependyma. Most studies have focused on studying the pathogenicity of NMO-IgG on astrocytes, and NMO is now considered an astrocytopathy. However, periependymal lesions are observed in NMO suggesting that ependymal cells could also be targeted by NMO-IgG. Ependymal cells regulate CSF-parenchyma molecular exchanges and CSF flow, and are a niche for sub-ventricular neural stem cells. Our aim was to examine the effect of antibodies from NMO patients on ependymal cells. We exposed two models, i.e. primary cultures of rat ependymal cells and explant cultures of rat lateral ventricular wall whole mounts, to purified IgG of NMO patients (NMO-IgG) for 24 hours. We then evaluated the treatment effect using immunolabelling, functional assays, ependymal flow analysis and bulk RNA sequencing. For each experiment, the effects were compared with those of purified IgG from a healthy donors and non-treated cells. We found that: (i) NMO-IgG induced aquaporin-4 agglomeration at the surface of ependymal cells and induced cell enlargement in comparison to controls. In parallel, it induced an increase in gap junction connexin-43 plaque size; (ii) NMO-IgG altered the orientation of ciliary basal bodies and functionally impaired cilia motility; (iii) NMO-IgG activated the proliferation of sub-ventricular neural stem cells; (iv) treatment with NMO-IgG up-regulated the expression of pro-inflammatory cytokines and chemokines in the transcriptomic analysis. Our study showed that NMO-IgG can trigger an early and specific reactive phenotype in ependymal cells, with functional alterations of intercellular communication and cilia, activation of sub-ventricular stem cell proliferation and the secretion of pro-inflammatory cytokines. These findings suggest a key role for ependymal cells in the early phase of NMO lesion formation.

On the eigenstructure of rotations and poses: commonalities and peculiarities

Locating vehicles, targets and objects in three-dimensional space is key to many fields of science and engineering such as robotics, aerospace, computer vision and graphics. Rotations and poses (position plus orientation) of bodies can be expressed in a variety of ways. Rotation matrices constitute one of the classic matrix Lie groups, the special orthogonal group— SO ( 3 ) . Poses can likewise be represented by matrices. One such representation is embodied in a 4 × 4 matrix establishing another famous matrix Lie group, the special Euclidean group— SE ( 3 ) . An alternative representation of pose uses 6 × 6 matrices and is referred to as the group of pose adjoints— Ad ( SE ( 3 ) ) . The eigenstructures of these representations reveal much about them from Euler’s theorem for rotations to the Mozzi–Chasles theorem for the general displacement of a rigid body. While the eigenstructure of SO ( 3 ) has been extensively studied, those of SE ( 3 ) and Ad ( SE ( 3 ) ) have hardly received the same scrutiny yet their structure is much richer. Motivated by their importance in kinematics and dynamics, we provide here a complete characterization of rotations and poses in terms of the eigenstructure of their matrix Lie group representations. An eigendecomposition of pose matrices reveals that they can be cast into a form similar to that of rotations although the structure of the former can vary depending on the nature of the pose involved. In particular, the pose matrices of SE ( 3 ) and Ad ( SE ( 3 ) ) cannot generally be diagonalized as can rotation matrices but they of course do yield to a Jordan normal form, from which we can identify a principal-axis pose in much the same manner that we can a principal-axis rotation. We also address the minimal polynomials for poses and derive a novel expression for the Jacobian in Ad ( SE ( 3 ) ) . Finally, we argue that the true counterpart to SO ( 3 ) for poses is not SE ( 3 ) but Ad ( SE ( 3 ) ) .

Queer disorientations in Only the Brave, Head On, and Blessed

ABSTRACT In this article, we explore the orientation of queer bodies to the city – and to Lisa French’s (2013) motif of ‘looking from the largely industrialised west at the city’ in particular – in three films directed by Ana Kokkinos: Only the Brave (1994), Head On (1998), and Blessed (2009). In doing so, we take up Sara Ahmed’s queer phenomenological approach to focus on Alex (played by Elena Mandalis) in Only the Brave; Ari (played by Alex Dimitriades) in Head On; and Arthur/‘Roo’ (played by Eamon Farren) in Blessed. We argue that when each queer protagonist looks to the city they are not only multiply disoriented, their disorientations are also specifically triggered by earlier enunciations of queer desire. We argue that these physical, psychological, temporal, and spatial disorientations serve multiple purposes across these films. They symbolise the phenomenological disorientations of queer embodiment; disorientate viewers to offer them a queer spectatorial opportunity; and proffer the ‘hope of new directions’ [Ahmed, Sara. 2006b. Queer Phenomenology. Durham, NC: Duke UP] in the depiction of queerness in Australian cinema.

9-DOF IMU-Based Attitude and Heading Estimation Using an Extended Kalman Filter with Bias Consideration.

The attitude and heading reference system (AHRS) is an important concept in the area of navigation, image stabilization, and object detection and tracking. Many studies and works have been conducted in this regard to estimate the accurate orientation of rigid bodies. In most research in this area, low-cost MEMS sensors are employed, but since the system’s response will diverge over time due to integration drift, it is necessary to apply proper estimation algorithms. A two-step extended Kalman Filter (EKF) algorithm is used in this study to estimate the orientation of an IMU. A 9-DOF device is used for this purpose, including a 6-DOF IMU with a three-axis gyroscope and a three-axis accelerometer, and a three-axis magnetometer. In addition, to have an accurate algorithm, both IMU and magnetometer biases and disturbances are modeled and considered in the real-time filter. After applying the algorithm to the sensor’s output, an accurate orientation as well as unbiased angular velocity, linear acceleration, and magnetic field were achieved. In order to demonstrate the reduction of noise power, fast Fourier transform (FFT) diagrams are used. The effect of the initial condition on the response of the system is also investigated.

Singularity-Free Lie Group Integration and Geometrically Consistent Evaluation of Multibody System Models Described in Terms of Standard Absolute Coordinates

Abstract A classical approach to the multibody systems (MBS) modeling is to use absolute coordinates, i.e., a set of (possibly redundant) coordinates that describe the absolute position and orientation of the individual bodies with respect to an inertial frame (IFR). A well-known problem for the time integration of the equations of motion (EOM) is the lack of a singularity-free parameterization of spatial motions, which is usually tackled by using unit quaternions. Lie group integration methods were proposed as an alternative approach to the singularity-free time integration. At the same time, Lie group formulations of EOM naturally respect the geometry of spatial motions during integration. Lie group integration methods, operating directly on the configuration space Lie group, are incompatible with standard formulations of the EOM, and cannot be implemented in existing MBS simulation codes without a major restructuring. The contribution of this paper is twofold: (1) A framework for interfacing Lie group integrators to standard EOM formulations is presented. It allows describing MBS in terms of various absolute coordinates and at the same using Lie group integration schemes. (2) A method for consistently incorporating the geometry of rigid body motions into the evaluation of EOM in absolute coordinates integrated with standard vector space integration schemes. The direct product group SO(3)×ℝ3 and the semidirect product group SE(3) are used for representing rigid body motions. The key element is the local-global transitions (LGT) transition map, which facilitates the update of (global) absolute coordinates in terms of the (local) coordinates on the Lie group. This LGT map is specific to the absolute coordinates, the local coordinates on the Lie group, and the Lie group used to represent rigid body configurations.

The neural coding of face and body orientation in occipitotemporal cortex

Face and body orientation convey important information for us to understand other people's actions, intentions and social interactions. It has been shown that several occipitotemporal areas respond differently to faces or bodies of different orientations. However, whether face and body orientation are processed by partially overlapping or completely separate brain networks remains unclear, as the neural coding of face and body orientation is often investigated separately. Here, we recorded participants’ brain activity using fMRI while they viewed faces and bodies shown from three different orientations, while attending to either orientation or identity information. Using multivoxel pattern analysis we investigated which brain regions process face and body orientation respectively, and which regions encode both face and body orientation in a stimulus-independent manner. We found that patterns of neural responses evoked by different stimulus orientations in the occipital face area, extrastriate body area, lateral occipital complex and right early visual cortex could generalise across faces and bodies, suggesting a stimulus-independent encoding of person orientation in occipitotemporal cortex. This finding was consistent across functionally defined regions of interest and a whole-brain searchlight approach. The fusiform face area responded to face but not body orientation, suggesting that orientation responses in this area are face-specific. Moreover, neural responses to orientation were remarkably consistent regardless of whether participants attended to the orientation of faces and bodies or not. Together, these results demonstrate that face and body orientation are processed in a partially overlapping brain network, with a stimulus-independent neural code for face and body orientation in occipitotemporal cortex.

Analysis of Numerical Method on Inverse Kinematics of Robotic Arm Welding with Artificial Intelligence

The key component of versatile production processes is robots. They are found in diverse systems where it is possible to bypass and optimize human function. I simulated a remote-control trickster in MATLAB with 6 degrees of freedom in this research. A robot is used in numerous applications, such as decoration, carpentry and equipment testing. In hardware verification labs, robotic arms are used to hold passive and power rail probes that connect from instruments like scopes and power supplies to PCB boards to protect the PCB layout from rip off due to sudden movement of the probes. Robot kinematics uses the geometry (position and orientation) of rigid bodies (links) and joints to control the movement of the robot. In this project, to control its movement, I have illustrated either forward or reverse enzyme kinetics of a device. Through Kinematics uses the positions of a joint to measure the end-effector position of the robot. The angles of the joints with the end-effector position are determined by inverse kinematics as the reference. There are several methods to calculate the forward and inverse kinematics such as analytical methods, numerical hit and trial, and iterative methods.

Planar cell polarity induces local microtubule bundling for coordinated ciliary beating

Multiciliated cells (MCCs) in tracheas generate mucociliary clearance through coordinated ciliary beating. Apical microtubules (MTs) play a crucial role in this process by organizing the planar cell polarity (PCP)-dependent orientation of ciliary basal bodies (BBs), for which the underlying molecular basis remains elusive. Herein, we found that the deficiency of Daple, a dishevelled-associating protein, in tracheal MCCs impaired the planar polarized apical MTs without affecting the core PCP proteins, causing significant defects in the BB orientation at the cell level but not the tissue level. Using live-cell imaging and ultra-high voltage electron microscope tomography, we found that the apical MTs accumulated and were stabilized by side-by-side association with one side of the apical junctional complex, to which Daple was localized. In vitro binding and single-molecule imaging revealed that Daple directly bound to, bundled, and stabilized MTs through its dimerization. These features convey a PCP-related molecular basis for the polarization of apical MTs, which coordinate ciliary beating in tracheal MCCs.
