Comparative analysis of the Angular 10 and Vue 3.0 frameworks

The aim of this article is to perform a comparative analysis of the Angular v10 and Vue v3.0 frameworks. The basis of the comparison is the performance tested with two applications that are similar in terms of functionality. The view with a variable number of displayed elements was examined, and the time was measured from the moment the number of components was indicated to the end of rendering. The amount of disk space occupied by the final applications and application segments was also compared in relation to the method of implementing their functionality. The results of the research allowed to formulate the conclusions that Vue is more efficient than Angular and additionally the Vue application takes up less disk space.

Clinical and Radiological Evaluation of Cage Subsidence Following Oblique Lumbar Interbody Fusion

Background Cage subsidence was previously reported as one of the most common complications following oblique lumbar interbody fusion (OLIF). We aimed to assess the impacts of CS on surgical results following OLIF, and determine its radiological characteristics and related risk factors. Methods Two hundred and forty-two patients underwent OLIF at L4-5 and with a minimum 12 months follow-up were reviewed. Patients were divided into three groups according to the extent disk height (DH) decrease during the follow-up: no CS (DH decrease ≤ 2 mm), mild CS (2mm < DH decrease ≤ 4 mm) and severe CS (DH decrease > 4mm). The clinical and radiological results were compared between groups to evaluate the radiological features, clinical effects and risk factors of CS. Results CS was identified in 79 (32.6%) patients, including 48 (19.8%) with mild CS and 31 (11.8%) with severe CS. CS mainly identified within 1 month postoperatively and did not progress after 3 months postoperatively, and more noted in the caudal endplate (44, 55.7%). In terms of clinical results, patients in the mild CS group were significantly worse than those in the no CS group, and patients in the severe CS group were significantly worse than those in the mild CS group. There was no significant difference in fusion rate between no CS (92.6%, 151/163) and mild CS (83.3%, 40/48) groups. However, significant lower fusion rate was observed in severe CS group (64.5%, 20/31) compared to no CS group. CS related risk factors included osteoporosis (OR = 5.976), DH overdistraction (OR = 1.175), flat disk space (OR = 3.309) and endplate injury (OR = 6.135). Conclusion CS following OLIF was an early postoperative complication. Higher magnitudes of CS were associated with worse clinical improvements and lower intervertebral fusion. Osteoporosis and endplate injury were significant risk factor for CS. Additionally, flat disk space and DH overdistraction were also correlated with the increased probability of CS.

HBASE Performance Analysis in Big Datasets Processing

The term Big Data has gained popularity in recent years due to technological developments and the accumulation of data from various sources, mobile devices and sensors. Hbase is a distributed open source environment that uses available disk space optimally and efficiently based on data. It organizes data in a very different way from standard relational databases and works with both structured and unstructured data. This article describes our experience and research on how the execution time for inserting datasets and selecting data depends on the size of the data volumes, the locations (nodes of the same or different networks) from which they send or retrieve and what is the effect of the selected data organization (especially RowKey design) on the execution time.

The effects of cages implantation on surgical and adjacent segmental intervertebral foramina

Objection The overarching goal of our research was to compare the clinical and radiological outcomes with different sizes of cages implantation in anterior cervical discectomy and fusion (ACDF), and to evaluate the effects on surgical and adjacent segmental intervertebral foramina. Methods The clinical data of 61 patients were analyzed retrospectively. The radiological data included the surgical intervertebral disk space height before (H0) and after surgery (H), the preoperative mean height of adjacent segments (Hm), the area and height of the surgical and adjacent segment foramen, the surgical segmental Cobb angle (α1), and C2-7Cobb angle (α2). The calculation of clinical data was conducted by Japanese Orthopaedic Association Scores (JOA), the recovery rate of JOA scores and visual analog scales (VAS). In accordance with the different ranges of distraction (H/Hm), patients were classified into three groups: group A (H/Hm<1.20, n=13), group B (1.20≤H/Hm≤1.80, n=37), and group C (H/Hm>1.80, n=11). Results After the operation and at the final follow-up, our data has demonstrated that the area and height of surgical segmental foramen all increased by comparing those of preoperation in three groups (all P<0.05). However, except for a decrease in group C (all P<0.05), the adjacent segmental foramina showed no significant changes (all P>0.05). The area and height of the surgical segment foramen and the distraction degree were positively correlated (0<R<1, all P<0.05), while the adjacent segments were negatively correlated with it (0<R<1, P=0.002~0.067). JOA scores improved markedly in all groups with similar recovery rates. However, during the final follow-up (P=0.034), it was observed that there were significant differences in visual simulation scores among the three groups. Conclusion The oversize cage might give a rise to a negative impact on the adjacent intervertebral foramen in ACDF. The mean value of the adjacent intervertebral disk space height (Hm) could be used as a reference standard. Moreover, the 1.20~1.80 fold of distraction (H/Hm) with optimal cages would achieve a better long-term prognosis.

An Improved Framework for Bitmap Indexes and their Use in Data Warehouse Optimization

Compression technique is basically used to compress the size of table or reduce the storage area. Oracle already gives this feature for the table compression as well as for the index compression. when index is created on particular column of a table then it contain some space, which require some storage or disk space by this technique we can save our disk space because in industry the company have to purchase the disk space according to the size of the their data and pay according to their disk space. To utilize this disk space for useful records data rather than wasting it. In this paper used the data pump utility for the compression of Bitmap index and table. Data pump utility performed for the logical backups in database.in this paper implemented data pump for compression, to release the space and change the index pointing location. It will not release the space even after deletion of records. This is of special interest for the case to compress the bitmap index and table space along with the’S (Data Manipulation Language).

libxtc: an efficient library for reading XTC-compressed MD trajectory data

Objective The purpose of this work is to optimize the processing of molecular dynamics (MD) trajectory data obtained for large biomolecular systems. Two popular software tools were chosen as the reference: the tng and the xdrfile libraries. Current implementation of tng algorithms and library is either fast or storage efficient and xdrfile is storage efficient but slow. Our aim was to combine speed and storage efficiency through the xdrfile’s code modification. Results Here we present libxtc, a ready-to-use library for reading MD trajectory files in xtc format. The effectiveness of libxtc is demonstrated for several biomolecular systems of various sizes (~ 2 × 104 to ~ 2 × 105 atoms). In sequential mode, the performance of libxtc is up to 1.8 times higher and 1.4 times lower than xdrfile and tng, respectively. In parallel mode, libxtc is about 3 and 1.3 times faster than xdrfile and tng. At the same time, MD data stored in the xtc format require about 1.3 times less disk space than those treated with the tng algorithm in the fastest reading mode, which is a noticeable saving especially when the MD trajectory is long and the number of atoms is large—this applies to most biologically relevant systems.

RELATIONSHIP BETWEEN DISABILITY AND RADIOGRAPHIC FINDINGS OF LUMBAR DISK DEGENERATION IN SAMPLE OF IRAQI PATIENTS WITH MECHANICAL LOW BACKACHE

Objectives: Disability related to chronic low back pain (LBP) is a complex and multidimensional phenomenon all over the world. The prevalence of backache in middle age and elderly is up to 84%. This study aims to evaluate the associations of X-ray features of lumbar disk degeneration with severity of disability among patients with mechanical LBP. Patients and Methods: A cross-sectional study was conducted on a total of 300 patients with chronic mechanical LBP. Severity of disability was measured using Modified Oswestry Disability Index and intensity of backache was assessed using numeric rating scale (0–10). X-ray features of lumbar disc degeneration according to Lane classification and spondylolisthesis were assessed in lateral recumbent lumbar X-rays. Results: The mean age of our sample was 52.45±7.87 and 71.7% of involved patients were women. Most patients were recorded as overweight or obese. The findings of disk space narrowing were mild in 65.7%, moderate in 28.7%, and severe in 5.6%, where the presence of osteophytes were small in 76.9%, moderate in 20.5%, and large in 2.6%. Regarding disability, two-third of cases were focused on minimal disability, followed by moderate, severe, and crippled as (26%), (6%), and (2%), respectively. There was highly significant association between women and pain radiation to legs (p=0.004). Obesity and overweight had meaningless effects on all markers. Conclusions: The severity of disability was significantly more in women, high intensity of lower back pain, presence of pain radiating to legs, moderate/severe disk space narrowing on X-ray, and disk degenerative disease score on X-ray, while age, presence of osteophytes and spondylolisthesis, body mass index, and pain duration were not associated with severity of disability.

Essential Skills for Working with Developers

There are specific technical resources that developers use that composers should also understand in order to have a productive workflow and to function as part of the team. One example of such a resource is version control, a system used to organize and track a team’s work by storing each change on a server. Though this is a surprisingly difficult resource to work with, it is discussed in this chapter in a concise and understandable manner. The optimization of audio is also a critical concept to understand when creating sound for a game. Each game has only a certain amount of hard disk space and memory allocated to the audio. Optimization is the technique of using this space as efficiently as possible so that one can achieve the desired sound without overloading the game’s resources. This chapter covers a variety of creative ways that composers can optimize their music without sacrificing quality.

Design and Analysis of Optimization and Tuning in Data Warehouses Using Bitmap Indexes

Introduction: An Index for Bitmaps is a special category that uses bitmaps or bit arrays in a database. Apache stores a bitmap for every index key in a bitmap file. Each main index stores multi-line pointers. Bitmap database management requires several time, but bitmap indexes are only appropriate for tables or tables that have occasionally updates. Method: Each bit of the map corresponds to a possible row id. If the bit is 1, it means that the row id contains this key value. An internal Oracle function converts the bit position to the corresponding row id, so that bitmap indexes offer the same functionality as B-tree indexes, despite the different internal representation. If the number of different values of the index is small, then the bitmap index will become very efficient in terms of the use of physical space. Result: Oracle involves the following compression features which are possible during the various operations in the database. This means we can compress the data on the following modes. There are several types of backup is possible in the database: • Whole Backup or partial backup • Full Backup or incremental backup • Cold or consistent backup • Hot or inconsistent backup Discussion: We study the current compression technologies, and add the compression of the bitmap index via the data pump. The bitmap index is more effective, for a minimum unique value, according to conventional wisdom. But it doesn't need either a bitmap index built on a high degree of cardinality or a low degree of cardinality through the data pump. In this paper, after deletion of documents, we propose data pump utility for releasing disk space in database. Bitmap index points the old location even after the table deletes information, this function does not release disk space. Conclusion: In this paper, we present the experiment evaluation of Bitmap Index Compression and release occupied disk space of database objects like table and indexes after deletion of records. Industrial database frequently allows the bulk data insertion and deletion. In database deletion of millions records from the table doesn't release occupied disk space immediately. Next steps in our research will be to release the disk space along with the deletion of records.
