Anatomical consideration and techniques in thread nose augmentation with mesh scaffold implant

Introduction Non-surgical rhinoplasty has evolved with the introduction of volumizing threads, which offer a less invasive alternative to traditional methods by enhancing nasal contours while minimizing filler use. This technique is gaining popularity, particularly in Southeast Asia, due to its shorter recovery time, reduced risk profile, and ability to prevent the ‘Avatar nose’ effect. However, there is limited anatomical guidance available for its application, especially in the Asian population. Materials and Methods This study analyzes the anatomical layers of the nose to guide the proper placement of volumizing threads. Three cases are presented, highlighting different approaches to nasal bridge enhancement, nasal tip augmentation, and combined use of threads and fillers. The placement of threads in the deep fat layer beneath the fibromuscular layer was emphasized to avoid vascular complications. Results The cases demonstrated with mesh thread (Tess Inc., Korea) successful outcomes with well-defined nasal contours and patient satisfaction. The techniques used allowed for precise enhancements while minimizing risks associated with superficial thread placement and vascular injury. Conclusion Volumizing threads provide an effective and safe method for non-surgical rhinoplasty, particularly when informed by a thorough understanding of nasal anatomy. The results support the growing use of this technique in esthetic practice, especially in regions like Southeast Asia.

Efficient protein structure archiving using ProteStAr.

The introduction of Deep Minds' Alpha Fold 2 enabled the prediction of protein structures at an unprecedented scale. AlphaFold Protein Structure Database and ESM Metagenomic Atlas contain hundreds of millions of structures stored in CIF and/or PDB formats. When compressed with a general-purpose utility like gzip, this translates to tens of terabytes of data, which hinders the effective use of predicted structures in large-scale analyses. Here, we present ProteStAr, a compressor dedicated to CIF/PDB, as well as supplementary PAE files. Its main contribution is a novel approach to predicting atom coordinates on the basis of the previously analyzed atoms. This allows efficient encoding of the coordinates, the largest component of the protein structure files. The compression is lossless by default, though the lossy mode with a controlled maximum error of coordinates reconstruction is also present. Compared to the competing packages, i.e. BinaryCIF, Foldcomp, PDC, our approach offers a superior compression ratio at established reconstruction accuracy. By the efficient use of threads at both compression and decompression stages, the algorithm takes advantage of the multicore architecture of current central processing units and operates with speeds of about 1 GB/s. The presence of Python and C++ API further increases the usability of the presented method. The source code of ProteStAr is available at https://github.com/refresh-bio/protestar.

Hand Embroidery and Visual Communication Nexus: Analysis of Temitayo Taofeek Badru’s Embroidered Works

Art has passed through a series of changes right from the first man in the cave, and artists through the ages have also explored different methods and materials. Such an aspect is the art of hand embroidery. Hand embroidery is a form of decorative stitches for embellishment on worn apparel and garments that was widely used in the past. This paper examines selected embroidered works by Temitayo Taofeek Badru. These artworks are coded with African philosophy, especially Yorùbá proverbs, sayings, myths, folklore and aphorisms, and social issues in society. This is to establish the development of creativity in embroidery works and artist's contributions to contemporary Nigerian art. The paper also discusses the biography and artistic development of the artist, classifies the selected works into expressionistic and Realistic styles, and analyses the symbolic forms of the works. Data were collected through oral interviews with the artist and participant observation method. Data were also gathered from journal articles and art exhibition catalogues of the artist. Descriptive and formal methods of art historical studies were used to analyse the data. The study revealed that Badru grew up in an environment that encouraged his artistic development. It was found that the artist mostly uses expressionistic and realistic styles in his embroidered works and that he sometimes combines the use of threads and acrylic paints for the realistic style he adopts. The paper concludes that Badru has taken Textile Art to a new dimension through the use of hand embroidery for artistic innovations, which has equally contributed to the development of contemporary Nigerian art.

Thread lifting as a modern method of non-radical face rejuvenation

Purpose of the study: The purpose of this review of scientific literature is to collect, systematize and update modern ideas about the types, methods and principles of thread lifting, taking into account the basic requirements for efficiency and safety.In this paper, we reviewed publications presented in scientific databases: Web of Science, Scopus, PubMed, Cochran library, Medline, and PubMed Central. The keywords for searching for materials were: thread lift, thread lift history, thread lift sutures, face thread lift, polylactic threads, polydioxanone threads.The earliest approach to the effective use of thread rejuvenation techniques was the use of non-absorbable threads based on polypropylene, which are still successfully used along with modern threads, among which a special place is occupied by absorbable threads and new modifications of non-absorbable ones, complemented by various fixing design features (notches, cones).A large selection of threads, techniques and principles of correction allows specialists to create an individual management plan for each patient, and continuity and synergy between the sequential use of different modifications of threads allows one to prolong the results obtained and delay or refuse more radical anti-aging surgeries on the face.At the same time, as a result of the review of the scientific literature, no published studies were found on the comparative analysis of thread and surgical methods of rejuvenation, which requires further study.

Slavic Textiles of the Last Quarter of the 1st Millennium AD: Study Results

The article is devoted to the analysis of the state of research and the introduction into scientific circulation of data on Slavic fabrics of the last quarter of the first millennium AD. In order to establish potential research opportunities, the general state of the study of fabrics in Ukraine according to archaeological remains is examined. Until now, the fabrics of the Slavs of the first quarter of the 1st millennium AD on the territory of modern Ukraine have not been studied. Their study is now available on the basis of fabric prints on clay products (13), as well as on the iron plate (1); the findings of actual fabrics of this period are currently unknown to the researchers. Such prints should be considered accidental, and their findings are extremely rare. It is hardly possible to count on further fast filling of this database. Local fabrication is not in doubt. Potentially, the existence of raw materials is evidenced by biological definitions (plants — flax and hemp; animals — sheep / goats) and the existence of the possibility of getting wool (spring scissors). The findings of spindle whorls directly certify the manufacture of threads. According to the imprints of the fibers, the existence of threads of both plant and animal origin was established. In four cases from Radychivske 3, the use of a stronger thread of vegetable origin for the warp and of animal thread for wefting was witnessed. In this way a better wear resistance of the fabric was achieved. The fabrics were plain weave, mostly the simplest, but from Radychivskе 3 comes their more complex type — mat R 4/4. The prevalence of this type should be left in question. A wide range of thread compressibility is indicated. It is from 0.03 to 2.5 mm. However, the thinnest of them probably indicate the wear of the fabric. Accordingly, the tissue density also differed significantly. The imprint with the densest weave — 23 × 23 n./cm2, comes from an iron plate. Probably, accidental prints on ceramics indicate that the potter may have had a rag of coarse cloth under his hands. Twist types (S and Z) are unlikely to reflect technological processes; instead, they may indicate the protective nature of the manufacture of threads. The twist angle (giving strength to the thread), which indicates the use of stronger threads for the warp is more important. Thus, the production of fabrics by the Slavs of the first quarter of the 1st millennium AD on the territory of modern Ukraine should be considered predominantly simple (though not primitive). Craftsmen used different raw materials, knew their benefits and could combine threads in the manufacture of fabric to improve its durability. The same is evidenced by the use of threads with different twisting angles.

LevioSAM: fast lift-over of variant-aware reference alignments.

MotivationAs more population genetics datasets and population-specific references become available, the task of translating (‘lifting’) read alignments from one reference coordinate system to another is becoming more common. Existing tools generally require a chain file, whereas VCF files are the more common way to represent variation. Existing tools also do not make effective use of threads, creating a post-alignment bottleneck.ResultsLevioSAM is a tool for lifting SAM/BAM alignments from one reference to another using a VCF file containing population variants. LevioSAM uses succinct data structures and scales efficiently to many threads. When run downstream of a read aligner, levioSAM is more than 7 times faster than an aligner when both are run with 16 threads.Availability and implementationSoftware Package: https://github.com/alshai/levioSAM, Experiments: https://github.com/langmead-lab/levioSAM-experimentsSupplementary information Supplementary data are available at Bioinformatics online.

HTSlib: C library for reading/writing high-throughput sequencing data.

BackgroundSince the original publication of the VCF and SAM formats, an explosion of software tools have been created to process these data files. To facilitate this a library was produced out of the original SAMtools implementation, with a focus on performance and robustness. The file formats themselves have become international standards under the jurisdiction of the Global Alliance for Genomics and Health.FindingsWe present a software library for providing programmatic access to sequencing alignment and variant formats. It was born out of the widely used SAMtools and BCFtools applications. Considerable improvements have been made to the original code plus many new features including newer access protocols, the addition of the CRAM file format, better indexing and iterators, and better use of threading.ConclusionSince the original Samtools release, performance has been considerably improved, with a BAM read-write loop running 5 times faster and BAM to SAM conversion 13 times faster (both using 16 threads, compared to Samtools 0.1.19). Widespread adoption has seen HTSlib downloaded >1 million times from GitHub and conda. The C library has been used directly by an estimated 900 GitHub projects and has been incorporated into Perl, Python, Rust, and R, significantly expanding the number of uses via other languages. HTSlib is open source and is freely available from htslib.org under MIT/BSD license.

Expert Consensus on Soft-tissue Repositioning Using Absorbable Barbed Suspension Double-needle Threads in Asian and Caucasian Patients.

Bioabsorbable barbed suspension double-needle threads have recently been thrust into the limelight as a minimally invasive alternative for skin repositioning. When compared to surgical face lifting, use of these threads requires reduced procedural and recovery time, no general anesthesia, confers immediate patient satisfaction, with no cutaneous incisions and no apparent scars, and is more tolerable. There is currently limited literature providing clinical guidance on the use of these suspension threads; hence, this consensus document was developed as the first publication to discuss the technical aspects of facial rejuvenation using the double-needle barbed bioabsorbable and hydrolyzable thread composed of copolymer poly (ε-caprolactone-co-L-lactic acid) or PCxLyA, that is, Definisse threads. The Board of Aesthetic Leaders and Investigators (BALI) is a panel of dermatologic surgery and plastic surgery experts who convened last July 2018 in Indonesia to discuss the aforementioned challenges. A thorough literature search was done where a review of specific technical recommendations based on prevailing practice and available guidelines pertaining to suspension threads were described and are summarized in this paper. A detailed list of pretreatment recommendations in the assessment of both Asian and Caucasian facial types, aging facial types, guidance on insertion techniques, and aftercare instructions for clinicians to review has been included here.

Cooperative Software-hardware Acceleration of K-means on a Tightly Coupled CPU-FPGA System

We consider software-hardware acceleration of K-means clustering on the Intel Xeon+FPGA platform. We design a pipelined accelerator for K-means and combine it with CPU threads to assess performance benefits of (1) acceleration when data are only accessed from system memory and (2) cooperative CPU-FPGA acceleration. Our evaluation shows that the accelerator is up to 12.7×/2.4× faster than a single CPU thread for the assignment/update step of K-means. The cooperative use of threads and FPGA is roughly 1.9× faster than CPU threads alone or the FPGA by itself. Our approach delivers 4×–5× higher throughput compared to existing offload processing approaches.

ORNAMENTAL MOTIVES OF NATIONAL CLOTHING EMBROIDERY OF THE TRANSCARPATHIA OF THE END OF THE XIX - FIRST HALF OF THE XX CENTURY (ON THE EXAMPLE OF THE FUND COLLECTION OF THE TRANSCARPATHIAN MUSEUM OF FOLK ARCHITECTURE AND LIFE)

The article on the basis of available literature and fund collection of Transcarpathian Museum of Folk Architecture and Life analyzes the patterns of clothing and interior embroidery collected by Maria Hrytsak. The author attempts to identify the most characteristic features of folk embroidery of the villages of Volovets, Tyachiv, Khust, Vynohradiv, Berehiv and Mukachevo districts. Most of the designs are fragments of embroidery from women's and men's shirts. This is a pleated part, narrow collar, embroidery on the sleeves and cuffs of women's shirts, as well as bibs and collar of men's shirts. They are chronologically dated to the late XIX and early XX centuries. For the Boykos of Transcarpathia, the embroidery of women's shirts is characterized by the embroidery of the chest part, the upper shoulder part of the sleeves and cuffs. One or three-row geometric compositions are dominate, in the 20-30's of the XX century stylized plants, rarely ornithomorphic were distributed. Folk embroidery of Dolinians of Tereblia is distinguished by lush ornamental compositions on the sleeves of women's shirts. There are several types of shirts that can be distinguished: zaspulnytsia, rukavy, kosutsia, bilenitsia. Special attention is deserved to the patterns of embroidery on the chest of men's festive shirts of the 20's and 40's of the XX century. A characteristic feature of the embroidery of the Dolinians of Korolevo was the use of threads of different colors. The embroidery of this region is characterized by five color variants. For embroidery of women's and men's shirts from the village Zavydovo of the Mukachevo district was characterized by the use of two techniques - the cross and the nyzyna. The most common were geometric floral ornamental compositions. In the embroidery of the village of Muzhievo in the Berehiv district, we observe mutual influences, as plant motives are dominant. Despite the Hungarian influences, the local embroidery still retains the geometric characteristic of the traditional Ukrainian embroidery of Transcarpathia. Realistic forms are very rare.

Iris recognition in unconstrained environment on graphic processing units with CUDA

Newly introduced Iris recognition systems (IRSs) run on serial processors. In this paper, an alternative method has been introduced for parallel processing on Graphic processing unit (GPU) with Compute unified device architecture (CUDA) in order to increase the speed of the system. The IRS has two main parallel processing criteria, which include the division of computations into hundreds of independent units and the time of calculation more than the time of transferring from the GPU. The IRS is divided into six stages including imaging, pre-processing, segmentation, normalization, feature extraction, and matching. In order to increase speed and accuracy, two stages of iris segmentation and matching play an important role in the IRS. In this paper parallel execution of an identical algorithm for these two stages has been used. The reason for paralleling the iris segmentation stage and their low speed matching is due to a great amount of information in the iris database, plenty of calculations and lack of data dependency in these two stages. For parallelism at the segmentation stage, for each radius, the Hough transform (HT) is a processor, and in the matching stage two parts are considered: The first part consists of 32 actions comparing the input code with the database code in parallel and in the second part 2048 bits with the use of threads on each processor is performed in two sub-sections in pairs of bits and in parallel with each other. Finally, the two-way coding is achieved. In compare of existing methods, this method has rather more accurate and is also superior in terms of processing time on the GPU with CUDA. The results of the implementation of the above method on the images in UBIRIS, BATH, CASIA and MMUI databases show that the proposed method has a precision accuracy of 99.12%, 97.98%, 98.80% and 98.34%, respectively, and the average speedup for parallel processing of images in the database in the proposed method on the GPU with CUDA are 18.8, 14.7, 18, and 19 times, respectively.

Thread as a Low-Cost Material for Microfluidic Assays on Intact Tumor Slices.

In this paper we describe the use of thread as a low-cost material for a microfluidic chemosensitivity assay that uses intact tumor tissue ex vivo. Today, the need for new and effective cancer treatments is greater than ever, but unfortunately, the cost of developing new chemotherapy drugs has never been higher. Implementation of low-cost microfluidic techniques into drug screening devices could potentially mitigate some of the immense cost of drug development. Thread is an ideal material for use in drug screening as it is inexpensive, widely available, and can transport liquid without external pumping hardware, i.e., via capillary action. We have developed an inexpensive microfluidic delivery prototype that uses silk threads to selectively deliver fluids onto subregions of living xenograft tumor slices. Our device can be fabricated completely for less than $0.25 in materials and requires no external equipment to operate. We found that by varying thread materials, we could optimize device characteristics, such as flow rate; we specifically explored the behavior of silk, nylon, cotton, and polyester. The incremental cost of our device is insignificant compared to the tissue culture supplies. The use of thread as a microfluidic material has the potential to produce inexpensive, accessible, and user-friendly devices for drug testing that are especially suited for low-resource settings.

Beyond Textiles: Alternative Uses of Twisted Fibres and Evidence from Akrotiri, Thera

Fibre crafts are among the oldest technological practices of mankind. Although commonly associated with textile manufacture, twisted fibres in the form of threads have always had a wider range of use in everyday life. Strings and ropes constitute a humble but essential category of fibre products deriving from the same technology and organic matter as threads. Due to their organic nature, however, they are rarely preserved in the archaeological record, unless special environmental conditions occur. This paper explores the research potential of the imprints of threads and strings in a study focusing on the alternative uses of fibre-spun artefacts. The focus is on the Bronze Age Aegean imprints of threads and strings preserved on objects made of clay and on wall paintings recovered at Akrotiri on Thera. The technical properties of the original threads and strings are evaluated through observation of their imprints, and the fibre technology used for their production is assessed. The methodologies of spindle whorl metrology and experimental spinning are also integrated in the discussion. Ultimately, the use of threads and strings for a variety of purposes, including but not limited to textile production, is discussed.

Use of Zymomonas mobilis immobilized in doped calcium alginate threads for ethanol production

Zymomonas mobilis immobilized in doped calcium alginate (Ca-alginate) threads was successfully employed for the production of ethanol in immobilized cell reactors operated with both vertical and horizontal flow. Polyethylene oxide (PEO) as a dopant for Ca-alginate threads was used to increase thread porosity. The influence of the direction of the flow into the reactor and the use of a dopant on the effectiveness of microbe immobilized Ca-alginate threads to produce ethanol was studied and results were compared to the widely used 2% Ca-alginate beads. Threads were able to obtain a similar ethanol yield to beads achieving 90.7% in vertical and 88% in horizontal flow reactors, while beads obtained 91% and 74.7%, respectively. The addition of PEO decreased the lag phase of the threads in both the horizontal and vertical flow reactors compared to a Ca-alginate standard over a 24 h period. The horizontal flow reactor's ethanol yield increased from 10.5% to 41.2% with the addition of PEO while the vertical flow reactor's ethanol yield increased from 15.5% to 69.6%. Additionally, doping with PEO lead to higher ethanol yield. This study demonstrates the use of threads for immobilization of microbes and the effectiveness of PEO as a dopant.

Pathomorphological criteria of use efficiency of resorbable and permanent implants in aesthetic medicine and cosmetic dermatology.

The use of threads in aesthetic medicine is based on its ability to stimulate collagen production, which is claimed by the manufacturers, but this information has no basis at all, as no research has been carried out that would confirm the claimed information. To determine effectiveness of collagenogenesis as a result of setting of resorbing and permanent implants on the basis of study pathomorphological changes in the skin. The studies were performed on 30 mature white male rats which were divided into two groups depending on the type of implanted threads. Dependence between type of implantation thread (structure) and stimulation of collagenogenesis has been established. While studying morphological changes in the peri-implant zone, it was found that in all groups of experimental rats, collagen with different term of biodegradation and in different quantities on various chronological stages is formed. It was established that collagenogenesis is stimulated unevenly, depending on the type of implantation thread (chemical composition and structure). On the 90th day of the experiment, the resorbing thread did not completely degrade, which does not contradict the information provided by the manufacturer about the period of disintegration (365days), and the expediency of using these cosmetic threads in aesthetic dermatology for the purpose of prolonged lifting skin correction. The specificity of the structure of implant threads, namely, the form of a spring (AS), as a provocative factor for long-term alteration, causes long-term inflammatory response in tissues (90th day of the experiment).

The role of suture cutout in the failure of meniscal root repair during the early post-operative period: a biomechanical study.

To assess the role of suture cutout in the mechanics of failure of the repaired posterior meniscal root during the early post-operative period when using sutures of different shape. Twenty medial porcine menisci were randomized in two groups depending on the suture shape used to repair the posterior root: thread or tape. The sutured menisci were subjected to cyclic loading (1000 cycles, (10, 30)N) followed by load-to-failure testing. Residual displacements, stiffness, and ultimate failure load were determined. During tests, the tissue-suture interface was recorded using a high-resolution camera. In cyclic tests, cutout progression at the suture insertion points was not observed for any specimen of either group and no differences in residual displacements were found between use of thread or tape. In load-to-failure tests, suture cutout started in all menisci at a load close to the ultimate failure and all specimens failed by suture pullout. Suture tape had a greater ultimate load with no other differences. In a porcine model of a repaired posterior meniscal root subjected to cyclic loads representative of current rehabilitation protocols in the early post-operative period under restricted loading conditions, suture cutout was not found as a main source of permanent root displacement when using suture thread or tape. Suture cutout progression started at high loading levels close to the ultimate load of the construct. Tape, with a meniscus-suture contact area larger than thread, produced higher ultimate load.

Opportunities and choice in a new vector era

This work discusses the significant changes in computing landscape related to the progression of Moore's Law, and the implications on scientific computing. Particular attention is devoted to the High Energy Physics domain (HEP), which has always made good use of threading, but levels of parallelism closer to the hardware were often left underutilized. Findings of the CERN openlab Platform Competence Center are reported in the context of expanding "performance dimensions", and especially the resurgence of vectors. These suggest that data oriented designs are feasible in HEP and have considerable potential for performance improvements on multiple levels, but will rarely trump algorithmic enhancements. Finally, an analysis of upcoming hardware and software technologies identifies heterogeneity as a major challenge for software, which will require more emphasis on scalable, efficient design.
