Effectiveness of a Novel 3D-Printed Nasoalveolar Molding Appliance (D-NAM) on Improving the Maxillary Arch Dimensions in Unilateral Cleft Lip and Palate Infants: A Randomized Controlled Trial

Objective: The aim of the current study was to introduce and measure the effectiveness of a new 3D-printed nasoalveolar molding (D-NAM) appliance on improving the maxillary arch dimensions (MADs) in infants with unilateral complete cleft lip and palate (UCLP) before surgical lip repair. Design: A prospective, balanced, randomized, parallel groups, single-blinded, controlled trial. Setting: All the steps of the current study were carried in the Department of Orthodontics, Cairo University in Egypt. Participants: Thirty-four, nonsyndromic infants with UCLP. Interventions: The eligible infants were randomly assigned into either no-treatment (control) or to the new D-NAM groups. In D-NAM group, the maxillary models were 3D scanned into virtual models onto which segmentation and alveolar segments approximation were performed. Approximation movements were divided into 3 models representing 3 activation steps. On each of these models, virtual appliance construction was performed followed by 3D printing of the appliance. Nasal stent was added manually to the appliances of the second and third steps. Horizontal tapes were applied to infants in the D-NAM group only. Main Outcomes Measures: A Blinded assessors carried all the MADs measurements virtually on digital models collected at the beginning (T1) and after (T2) treatment. Results: Clinically and/or statistically significant improvements in all the measured MADs were recorded in D-NAM group at T2 before surgical lip repair in comparison to control group. Conclusions: The introduced D-NAM/3D-printed appliance is a simple and efficient technique to improve the MADs in infants with UCLP before surgical lip repair.

Analisis Teknologi Virtual Mesin Proxmox Dalam Rangka Persiapan Infrastruktur Server

Teknologi virtualisasi dalam dunia komputasi saat ini menjadi topik hangat untuk diperbincangkan dalam pembahasan riset teknologi yang dipergunakan pada server. Virtualisasi dan kontainer merupakan bagian yang sangat penting dalam pengoptimalisasian server, karena sangat berpengaruh pada efisiensi pengelolaan resource infrastruktur server itu sendiri. Pembuatan sebuah server yang baik membutuhkan biaya yang tidak sedikit apalagi untuk membangun hingga menjadi sebuah cloud computing. Supaya biaya dapat ditekan dan murah maka digunakanlah virtualisasi server. Virtualisasi server ialah membangun server pada sebuah komputer atau laptop menggunakan media machineware. Dalam VM tersebut dibangun beberapa server dengan sistem operasi berbeda, baik dari Microsoft Windows maupun Linux dengan variannya, semua sistem operasi berjalan bersamaan. Proxmox merupakan software open source Virtualization Platform untuk menjalankan Virtual Appliance dan Virtual Machine. Proxmox VE adalah distro khusus yang didedikasikan secara khusus sebagai mesin host virtualisasi sistem dan memuat 2 teknologi virtualisasi, yaitu KVM dan OpenVZ. Dari basil penelitian dapat disimpulkan bahwa ProxmoxVE dapat menjalankan mesin virtual secara penuh layaknya baremetal hypervisor. Hal ini ditunjukkan dengan berjalannya beberapa VM dalam satu server untuk menjalankan sistem maupun aplikasi yang dipergunakan pada institusi tersebut sehingga dapat menekan pengeluaran biaya untuk pembelian server.

Belle2Lab - An Interactive Tool for a Public Analysis of the Belle II Data

Several data samples from a Belle II experiment will be available to the public as a part of the experiment outreach activities. A Belle2Lab tool is designed as an interactive graphical user interface to reconstructed particles, offering users basic particle selection tools. The tool is based on a Blockly JavaScript graphical code generator and can be run in an HTML5 capable browser. It allows a description of different particle decays by selecting and combining particles from the data file, easy histogramming tools and a display of the results by using the JSROOT library. During the analysis, the user has the possibility to apply cuts to the selected variables. A pseudo-code generated by the user interface is sent to the execution server which returns the histograms, that can also be interactively fitted. The Belle2Lab is accessible in two ways: hosted on a single public web server or as a part of the virtual appliance which consists of an Ubuntu 16.04 LTS operating system, a data sample, an analysis framework, and a private web server. The public web server can be used for a single access while the virtual appliance is more suited for a use in a classroom.

Ceaseless Virtual Appliance Streaming

Cloud computing is modus operandi of manipulating server clusters hosted at secluded sites on Internet for storage, processing, and retrieval of data. It tenders suppleness, disaster recovery, competitiveness, and cutback in capital and operational cost for ventures, principally small and medium ones, which hold meager resource base. Virtualization at plinth of cloud computing sanctions utilizing physical hardware stratum to frame and administer virtualized infrastructure, storage areas, and network interfaces. Virtual machines, administered on clouds to seize inherent advantages of virtualization, are fabricated on storage area networks (Armbrust et al., 2009). But whenever user endeavors to access them from remote location it resulted in hundreds of megabytes of data reads and ensuing congestion in network. Question is how to instigate virtual machines and load their applications in minimal time. The ingenious Ceaseless Virtual Appliance Streaming system assures virtual machine's streaming just like video on demand. It trims down burden over existing resources and offers improved network utilization.
