Splice Variant of Spalax Heparanase Skipping Exon 12.

The subterranean blind mole rat, Spalax, has evolved significantly over 47 million years to thrive in its underground habitat. A key enzyme in this adaptation is heparanase, which degrades heparan sulfate (HS) in the extracellular matrix (ECM), facilitating angiogenesis and releasing growth factors for endothelial cells. Spalax heparanase has various splice variants influencing tumor growth and metastasis differently. We report a novel splice variant from a hypoxia-exposed kidney sample resulting from exon 12 skipping. This variant maintains the translation frame but lacks enzymatic activity, offering insights into Spalax's unique adaptations.

Comparison of software packages for detecting unannotated translated small open reading frames by Ribo-seq.

Accurate and comprehensive annotation of microprotein-coding small open reading frames (smORFs) is critical to our understanding of normal physiology and disease. Empirical identification of translated smORFs is carried out primarily using ribosome profiling (Ribo-seq). While effective, published Ribo-seq datasets can vary drastically in quality and different analysis tools are frequently employed. Here, we examine the impact of these factors on identifying translated smORFs. We compared five commonly used software tools that assess open reading frame translation from Ribo-seq (RibORFv0.1, RibORFv1.0, RiboCode, ORFquant, and Ribo-TISH) and found surprisingly low agreement across all tools. Only ~2% of smORFs were called translated by all five tools, and ~15% by three or more tools when assessing the same high-resolution Ribo-seq dataset. For larger annotated genes, the same analysis showed ~74% agreement across all five tools. We also found that some tools are strongly biased against low-resolution Ribo-seq data, while others are more tolerant. Analyzing Ribo-seq coverage revealed that smORFs detected by more than one tool tend to have higher translation levels and higher fractions of in-frame reads, consistent with what was observed for annotated genes. Together these results support employing multiple tools to identify the most confident microprotein-coding smORFs and choosing the tools based on the quality of the dataset and the planned downstream characterization experiments of the predicted smORFs.

Fluidic undulation effects on carangiform swimmers propelled by internal active bending moments

With different shapes and material properties, fish all achieve undulatory swimming gait under the action of internal active muscle stimulation and external fluid forces. Such locomotion can be decomposed into deformation affected by internal and external forces in the body frame and overall translation and rotation solely determined by fluid forces. In order to revisit the undulatory swimming gait, we investigate the hydrodynamic performance of two-dimensional flexible carangiform swimmers with varying stiffnesses and thicknesses, which are driven by the active internal bending moments, and employ the complex orthogonal decomposition and Fourier decomposition methods to quantitatively measure and analyze the proportion of undulation. It is found that standing wave deformation characteristics are prominently observed along fish-like bodies with high stiffness, whereas traveling wave characteristics are more evident in bodies with lower stiffness. The self-propelled fish body demonstrates lateral oscillation and rotation around its center of mass, namely, the heaving and pitching movement, particularly in specimens with high stiffness. The present analysis shows that the heaving and pitching locomotion induced by the fluid significantly increase the traveling wave proportion by modulating the amplitude and phase of the left and right traveling waves viewed in forward frame. We called it fluidic undulation effects (FUE), which is different from the undulation of body deformation. This effect is more pronounced for large stiffnesses and thin airfoils. The standing wave deformation observed with a large stiffness transforms into a traveling wave propulsion pattern, with its traveling wave index even slightly surpassing that of a small-stiffness pattern. Although the efficiency of the standing wave deformation is low, it facilitates a faster forward speed (body lengths per stroke). The positive impact of the FUE on the swimming performance is also confirmed by restricting the recoil motions of the lateral translation and rotation of the body. Furthermore, we observe that there is no undulatory swimming gait that has both the highest energy efficiency and the highest speed.

SARS-CoV-2 Nsp1 cooperates with initiation factors EIF1 and 1A to selectively enhance translation of viral RNA.

A better mechanistic understanding of virus-host dependencies can help reveal vulnerabilities and identify opportunities for therapeutic intervention. Of particular interest are essential interactions that enable production of viral proteins, as those could target an early step in the virus lifecycle. Here, we use subcellular proteomics, ribosome profiling analyses and reporter assays to detect changes in protein synthesis dynamics during SARS-CoV-2 (CoV2) infection. We identify specific translation factors and molecular chaperones that are used by CoV2 to promote the synthesis and maturation of its own proteins. These can be targeted to inhibit infection, without major toxicity to the host. We also find that CoV2 non-structural protein 1 (Nsp1) cooperates with initiation factors EIF1 and 1A to selectively enhance translation of viral RNA. When EIF1/1A are depleted, more ribosomes initiate translation from a conserved upstream CUG start codon found in all genomic and subgenomic viral RNAs. This results in higher translation of an upstream open reading frame (uORF1) and lower translation of the main ORF, altering the stoichiometry of viral proteins and attenuating infection. Replacing the upstream CUG with AUG strongly inhibits translation of the main ORF independently of Nsp1, EIF1, or EIF1A. Taken together, our work describes multiple dependencies of CoV2 on host biosynthetic networks and proposes a model for dosage control of viral proteins through Nsp1-mediated control of translation start site selection.

Genomic and phenotypic characterization of multidrug-resistant Salmonella enterica serovar Reading isolates involved in a turkey-associated foodborne outbreak.

Salmonella is a global bacterial foodborne pathogen associated with a variety of contaminated food products. Poultry products are a common source of Salmonella-associated foodborne illness, and an estimated 7% of human illnesses in the United States are attributed to turkey products. From November 2017 to March 2019, the Centers for Disease Control and Prevention reported a turkey-associated outbreak of multidrug-resistant (MDR; resistant to ≥3 antimicrobial classes) Salmonella enterica serovar Reading (S. Reading) linked to 358 human infections in 42 US states and Canada. Since S. Reading was seldom linked to human illness prior to this outbreak, the current study compared genomic sequences of S. Reading isolates prior to the outbreak (pre-outbreak) to isolates identified during the outbreak period, focusing on genes that were different between the two groups but common within a group. Following whole-genome sequence analysis of five pre-outbreak and five outbreak-associated turkey/turkey product isolates of S. Reading, 37 genes located within two distinct chromosomal regions were identified only in the pre-outbreak isolates: (1) an ~5 kb region containing four protein-coding genes including uidA which encodes beta-glucuronidase, pgdA encoding peptidoglycan deacetylase, and two hypothetical proteins and (2) an ~28 kb region comprised of 32 phage-like genes and the xerC gene, which encodes tyrosine recombinase (frequently associated with phage genes). The five outbreak isolates also had a deletional event within the cirA gene, introducing a translational frame shift and premature stop codon. The cirA gene encodes a protein with dual receptor functions: a siderophore receptor for transport of dihydroxybenzoylserine as well as a colicin Ia/b receptor. Significant differences for the identified genetic variations were also detected in 75 S. Reading human isolates. Of the 41 S. Reading isolates collected before or in 2017, 81 and 90% of the isolates contained the uidA and pgdA genes, respectively, but only 24% of the isolates collected after 2017 harbored the uidA and pgdA genes. The truncation event within the cirA gene was also significantly higher in isolates collected after 2017 (74%) compared to before or in 2017 (5%). Phenotypic analysis of the S. Reading isolates for colicin and cefiderocol sensitivities (CirA) and β-methyl-D-glucuronic acid utilization (UidA and accessory proteins) supported the genomic data. Overall, a similar genome reduction pattern was generally observed in both the turkey and human isolates of S. Reading during the outbreak period, and the genetic differences were present in genes that could potentially promote pathogen dissemination due to variation in Salmonella colonization, fitness, and/or virulence.

Анализ мультигенных семейств вируса африканской чумы свиней

The article presents summarized data on the multigene families of the African swine fever virus (MGF). A feature of the ASF virus is the presence of a large number of multigene families. It is generally accepted that multigene family proteins are widely distributed in the African swine fever virus (ASF) genome and are generally classified into five families, including MGF-100, MGF-110, MGF-300, MGF-360, and MGF-505. The multigene families of the ASF virus are located in both the left and right variable regions of the genome. It is known that multigene families 110 and 300 are located on the left end of the genome, and MGS 100 on the right, and MGS360, MGS505 and MGS530 at both ends of the genome. Most MGS families have copies at each end of the genome. Multigene families are responsible for the virulence and replication of the ASF virus. Several genes belonging to the 360 and 505/530 families determine the host range of the ASF virus and its virulence. The 530 multigene family contains six different reading frames encoding an average of five hundred and thirty amino acids containing four highly conserved domains. MGS300 consists of three open translation frames encoding an average of three hundred amino acids containing three highly conserved domains. The amino-terminal regions of the proteins encoded by MGS-530 and 300 have significant similarity to each other, as well as to the corresponding regions. Most researchers believe that MGS evolved through a process of duplication and sequence divergence. Elements of multigene families are located close to each other and are read in only one direction.

Generalized dynamics equation with causal symmetry

ABSTRACT The particle dynamics equation’s formal logic is examined in the context of classical mechanics to investigate the nature of inertial forces. First, a fresh perspective on the dual dependence of the inertial reference frame and inertial force in Newtonian dynamics is presented. The causal relationship between the two sides of Newton’s second law is found to be asymmetrical and inconsistent. Secondly, a more general particle dynamics equation, applicable in any translational frame of reference without additional assumptions, is introduced. Essentially, Newton’s second law is only an extreme case of the newly generalized dynamics equation since in Newton’s second law an entire term of the forces acting on the reference object is omitted. The nature of inertial force is unveiled as the mass-ratio weighted real force acting on the reference object. This qualitative explanation is entirely naturalistic as the reference frame’s acceleration depends directly on the acceleration of its reference object(s), and the acceleration of every reference object depends directly on the forces acting on this reference object.

Study on the Translation of Culture-loaded Words in Red Sorghum from the Perspective of Frame Theory

Frame theory is an important guide for subtitle translation in films. From the perspective of frame theory, subtitle translation is a process of translators' understanding of the original text and construction of the translation frame to achieve frame equivalence. Due to the cross-cultural conversion of cultural factors, the translation of Chinese culture-loaded words often becomes a thorny problem for translators, and scholars have long studied the translation of culture-loaded words from different perspectives. However, few scholars have used the framework theory to study the translation of culture-loaded words in subtitles. Therefore, based on the frame theory, this paper takes the Berlin International Film Festival award-winning film "Red Sorghum" as an example, and explores its translation strategies from three aspects: frame replacement, frame transplantation and frame adjustment by comparing and analyzing the Chinese subtitles and their translations.

Spatial navigation metrics differentiating preclinical and prodromal Alzheimer’s disease: a systematic review

AbstractBackgroundIncreasing evidence suggests that impairments of spatial navigation, orientation and memory may represent one of the earliest features Alzheimer’s disease (AD), preceding deficits in other cognitive domains.

Clinical Manifestations.

Working through frame incongruences: A process perspective on (re)framing for digital servitization

Industrial firms are increasingly seeking new means of competitiveness through digital servitization that involves incorporating digital services and platforms. Despite the growing prominence of digital servitization, we have yet to understand how such changes are being framed, reframed, and unfold in industrial firms. To this end, we undertake an in-depth longitudinal exploratory case study of an industrial firm to understand the organizational framing and reframing activities vis-à-vis digital servitization. Our findings identify how motivational, diagnostic, and prognostic framing gradually unfolds over distinct phases. Specifically, our findings reveal the occurrence of frame incongruence among different groups of actors, compelling the firm to engage in strategies and tactics to achieve frame alignment. Notably, we identify that management engages in the alignment processes of frame extension, translation, and clarification, which creates a space of workable certainty. While transient in nature, this state of workable certainty serves as a catalyst in propelling the firm forward in its pursuit of a digital servitization strategy. By shedding light on the process of digital reframing that firms undertake in order to materialize their digital servitization strategy, our study contributes to a deeper understanding of this phenomenon. Moreover, we raise pertinent managerial implications for firms embarking on the path of digital servitization, emphasizing the imperative of continuous attention to the ongoing framing and reframing processes accompanying such change endeavors.

Orbit-attitude-structure coupled modelling method in local translational coordinate frame for multibody systems

The absolute coordinate-based (ACB) method, including absolute nodal coordinate formulation and natural coordinate formulation, is a widely-used dynamic modelling method for multibody systems. However, the problem of accuracy loss would arise when multi-scale motions are described in the same global coordinate system, such as large-scale orbital motions, small-scale attitude motions and structural vibrations, and micro-scale contact/collision. To address this problem, an ACB method in local translational coordinate system is proposed such that the large-scale orbital motions can be separated from other smaller-scale motions. The dynamic equations are derived by the Hamilton's equations and the Kronecker product. The validity of the proposed method is studied using an orbit-attitude coupled model of an orbiting rigid plate. It is found that the attitude errors of the original ACB method increase as time step size decreases. The reason for this counterintuitive phenomenon is that more serious accuracy loss is encountered for smaller time step size. In addition, more iterations are required for the original ACB method to obtain the prescribed tolerable error in each time step due to accuracy loss. In comparison, the proposed method is more accurate and efficient in numerical simulations. Finally, the proposed method is applied to the orbit-attitude-structure coupled simulation of a space robotic system.

Spatial imagination in colonial Bengal

ABSTRACT This essay traces a changing geo-politics brought about by the forces of Western colonisation. It maps the intellectual pathways two Bengalis – Raja Rammohun Roy and Ishwarchandra Vidyasagar – chalked out in their negotiations with real and mythical spaces of the East and the West. The fashioning of their own self-identities then becomes a part of this process. The evolution of Roy’s analytical frame, and Vidyasagar’s literary frame for examining and romancing the West is laid out, after the historical context is explained. Roy’s reflexive engagement with the Occident was to travel and see for himself this land of fantasy (which remained an elite practice and which Roy sets in motion). Ishwarchandra’s literary frame of translation formed a deep pool of imagination within indigenous minds – an internalised geographical space which did not need a validity check – therefore representing a deeper colonial penetration of the Bengali/Indian imagination.

Development of nanoRibo-seq enables study of regulated translation by cortical neuron subtypes, showing uORF translation in synaptic-axonal genes

Investigation of translation in rare cell types or subcellular contexts is challenging due to large input requirements for standard approaches. Here, we present "nanoRibo-seq" an optimized approach using 102- to 103-fold less input material than bulk approaches. nanoRibo-seq exhibits rigorous quality control features consistent with quantification of ribosome protected fragments with as few as 1,000 cells. We compare translatomes of two closely related cortical neuron subtypes, callosal projection neurons (CPN) and subcerebral projection neurons (SCPN), during their early postnatal development. We find that, while translational efficiency is highly correlated between CPN and SCPN, several dozen mRNAs are differentially translated. We further examine upstream open reading frame (uORF) translation and identify that mRNAs involved in synapse organization and axon development are highly enriched for uORF translation in both subtypes. nanoRibo-seq enables investigation of translational regulation of rare cell types invivo and offers a flexible approach for globally quantifying translation from limited input material.

High-resolution mapping reveals the mechanism and contribution of genome insertions and deletions to RNA virus evolution

RNA viruses rapidly adapt to selective conditions due to the high intrinsic mutation rates of their RNA-dependent RNA polymerases (RdRps). Insertions and deletions (indels) in viral genomes are major contributors to both deleterious mutational load and evolutionary novelty, but remain understudied. To characterize the mechanistic details of their formation and evolutionary dynamics during infection, we developed a hybrid experimental-bioinformatic approach. This approach, called MultiMatch, extracts insertions and deletions from ultradeep sequencing experiments, including those occurring at extremely low frequencies, allowing us to map their genomic distribution and quantify the rates at which they occur. Mapping indel mutations in adapting poliovirus and dengue virus populations, we determine the rates of indel generation and identify mechanistic and functional constraints shaping indel diversity. Using poliovirus RdRp variants of distinct fidelity and genome recombination rates, we demonstrate tradeoffs between fidelity and Indel generation. Additionally, we show that maintaining translation frame and viral RNA structures constrain the Indel landscape and that, due to these significant fitness effects, Indels exert a significant deleterious load on adapting viral populations. Conversely, we uncover positively selected Indels that modulate RNA structure, generate protein variants, and produce defective interfering genomes in viral populations. Together, our analyses establish the kinetic and mechanistic tradeoffs between misincorporation, recombination, and Indel rates and reveal functional principles defining the central role of Indels in virus evolution, emergence, and the regulation of viral infection.

An equivariant neural operator for developing nonlocal tensorial constitutive models

Developing robust constitutive models is a fundamental and longstanding problem for accelerating the simulation of multiscale physics. Machine learning provides promising tools to construct constitutive models based on various calibration data. However, with either traditional or machine learning techniques, the constitutive model for tensorial quantities has been much less studied than scalar quantities due to more complicated physics, even though the former plays an important role in many scientific and engineering applications. In this work, we propose a neural operator to develop nonlocal constitutive models for tensorial quantities through a vector-cloud neural network with equivariance (VCNN-e). The VCNN-e respects all the invariance properties desired by constitutive models, faithfully reflects the region of influence in physics, and is applicable to different spatial resolutions. By design, the model guarantees that the predicted tensor is invariant to the frame translation and ordering (permutation) of the neighboring points. Furthermore, it is equivariant to the frame rotation, i.e., the output tensor co-rotates with the coordinate frame. We evaluate the VCNN-e by using it to emulate the Reynolds stress transport model for turbulent flows, which directly computes the Reynolds stress tensor to close the Reynolds-averaged Navier–Stokes (RANS) equations. The evaluation is performed in two situations: (1) emulating the Reynolds stress model through synthetic data generated from the Reynolds stress transport equations with closure models, and (2) predicting the Reynolds stress by learning from data generated from direct numerical simulations. Such a priori evaluations of the proposed network on realistic and challenging datasets pave the way for developing and calibrating robust and nonlocal, non-equilibrium constitutive models for the RANS equations and other mechanical problems.

Etiology of oncogenic fusions in 5,190 childhood cancers and its clinical and therapeutic implication

Oncogenic fusions formed through chromosomal rearrangements are hallmarks of childhood cancer that define cancer subtype, predict outcome, persist through treatment, and can be ideal therapeutic targets. However, mechanistic understanding of the etiology of oncogenic fusions remains elusive. Here we report a comprehensive detection of 272 oncogenic fusion gene pairs by using tumor transcriptome sequencing data from 5190 childhood cancer patients. We identify diverse factors, including translation frame, protein domain, splicing, and gene length, that shape the formation of oncogenic fusions. Our mathematical modeling reveals a strong link between differential selection pressure and clinical outcome in CBFB-MYH11. We discover 4 oncogenic fusions, including RUNX1-RUNX1T1, TCF3-PBX1, CBFA2T3-GLIS2, and KMT2A-AFDN, with promoter-hijacking-like features that may offer alternative strategies for therapeutic targeting. We uncover extensive alternative splicing in oncogenic fusions including KMT2A-MLLT3, KMT2A-MLLT10, C11orf95-RELA, NUP98-NSD1, KMT2A-AFDN and ETV6-RUNX1. We discover neo splice sites in 18 oncogenic fusion gene pairs and demonstrate that such splice sites confer therapeutic vulnerability for etiology-based genome editing. Our study reveals general principles on the etiology of oncogenic fusions in childhood cancer and suggests profound clinical implications including etiology-based risk stratification and genome-editing-based therapeutics.

Imaging suprathermal x-rays from a laboratory plasma jet using PIN-diode-based and scintillator-based 1D pinhole/coded aperture cameras.

A PIN-diode-based 1D x-ray camera and a scintillator-based 1D x-ray camera, both with a microsecond to submicrosecond time resolution, have been developed to perform time-resolved imaging of transient, low-intensity, suprathermal x-rays associated with magnetohydrodynamic instabilities disrupting a plasma jet. These cameras have a high detection efficiency over a broad x-ray band, a wide field of view, and the capability to produce >50 time-resolved frames with a ≤1 μs time resolution. The x-ray images are formed by a pinhole or by a coded aperture placed outside a vacuum chamber in which the plasma jet is launched. The 1D imaging shows that the location of the x-ray source is either a few centimeters away from an inner disk electrode or near a spatially translatable metal frame that is 30-40cm away from the electrode. Compared to a pinhole, a coded aperture increases the signal collection efficiency but also introduces unwanted artifacts.

A constructive deep convolutional network model for analyzing video-to-image sequences

This paper proposes a new technique to add sign language as a special and real-time feature. In addition to gestures, sign language also uses grammatical rules, linguistic frameworks, etc. We require a method that can extract meaningful sentences from non-manual features. Utilizing techniques from computer graphics, neurologic music therapy, and NN-based image/video formation, this is accomplished. Our goal is to use this to process dynamic images for output generation and real-time classification. Current CNN-based techniques operate by taking the entire video as input, dividing it into layers for the classifier to work on, and then combining and providing the output to the user. Here, Convolutional Deep VGG-16 (CDVGG-16) classifiers adopted for sign feature learning, which is iteratively trained and tested. Their architecture consists of blocks, where each block is composed of 2D Convolution and Max Pooling layers. We prefer VGG-16 over VGG-19 in order to improve feature extraction and decrease overfitting. The captured sign language video processing with some pre-processing and classification steps leads to the extraction of sign language feature space assisting deaf people. As a positive approach, the Sign Language Recognition (SLR) modeling framework with deep learning is introduced as it includes various notable advantages. There are three essential phases for provisioning the SLR framework: (1) data acquisition, (2) image pre-processing, and (3) CDVGG-16 classifier. The simulation is done with the MATLAB 2020a environment with various performance metrics like accuracy, precision, F-measure, recall and running time. The promising results show that real-world SLR applications can be formed using the suggested SLR paradigm. The proposed CDVGG-16 gives 95.6% prediction accuracy, 85.6% precision, 99.9% recall, 96.8% F-measure and 0.125 s running time. For improved performance, our proposed method employs normalization and examines sequential image frames. The results and accuracy indicate that it is a suitable method for video-image classification, as expected, and that deep layers and data augmentation can be used to address any overfitting and underfitting issues. Instead of being a literal translation frame by frame, the filter size is adjusted to ensure that output is translated appropriately given the context.
