Abstract Background Percutaneous minimally invasive retrograde screw fixation is a widely accepted treatment strategy for patients with superior ramus fractures and has shown good biomechanical stability compared to plating. Recently, elastic stable intramedullary nailing (ESIN) devices have been proposed as an alternative in the of fractures. However, studies on this new are lacking. Thus, aim study was compare ESIN pubic versus fixation. Methods Standardized (Nakatani type II) were created...
To date, there have been no studies describing the characteristics of posteromedial fragment in posterior malleolus fracture. The aim was to investigate variability fracture fragments enable better surgical planning.All Mason and Molloy type 2B fractures, defined as both posterolateral malleolus, from our database were identified analyze preoperative computed tomography scan. investigated 47 cases (mean age, 46.6 years; 11 male, 36 female).Morphologically, could be divided into 2 subtypes:...
The aim of this study was to evaluate the influence introduction online podcasts as part main lecture series in orthopaedics on number attendees, examination results and assessment teaching by students. Additionally, we evaluated use other media for preparation.At beginning end questionnaires were handed out students their attitudes towards attending lectures, video preparation. In addition, attendees podcast usage during semester counted statements evaluation assessments orthopaedic...
In the run-up to biomechanical testing, fresh human tissue samples are often frozen in order inhibit initial decomposition processes and achieve a temporal independence of acquisition from testing. The aim this study was compare mechanical properties iliotibial tract (IT) fresh-frozen taken same IT those modified with different concentrations Dimethylsulfoxide (DMSO) prior freezing. All were partial plastinated destructive tensile tests conducted uniaxial test setup. A plastination technique...
Osteoarthritis of the first metatarsophalangeal joint (hallux rigidus) leads to pain and poor function mobility. Arthrodesis is gold standard treatment for end-stage disease. Total arthroplasties have been attempted, but early loosening has attributed dorsally directed shear forces on metatarsal component. Metallic proximal phalangeal hemiarthroplasty theoretically avoids this. Whilst results are promising, no comparative trials exist comparing this arthrodesis. The primary objectives...
Abstract The development of an LHC physics analysis involves numerous investigations that require the repeated processing terabytes data. Thus, a rapid completion each these cycles is central to mastering science project. We present solution efficiently handle and accelerate analyses on small-size institute clusters. Our uses three key concepts: vectorized collision events, “MapReduce” paradigm for scaling out computing clusters, utilized SSD caching reduce latencies in IO operations. This...
Atraumatic necrosis of the femoral head (AFHN) is a common disease with an incidence 5000-7000 middle-aged adults in Germany. There no uniform consensus literature regarding configuration bone AFHN. The clinical picture our patients varies from very hard bone, especially idiopathic findings, and rather soft cortisone-induced necrosis. A better understanding underlying process could be decisive for establishing morphology-dependent approach. aim this study closer examination condition AFHN...
Intraoperative proximal femoral fractures (IPFF) represent a rare but challenging complication of total hip arthroplasties. They usually occur as longitudinal split. This pilot trial aimed to compare the biomechanical primary stability different fixation techniques for IPFF. Standardised medial split femur (type II, Modified Mallory Classification) were created in artificial osteoporotic and non-osteoporotic composite femora after implantation cementless stem. Five compared: cerclage band,...
Category: Trauma; Ankle Introduction/Purpose: Diaphyseal tibial fractures account for approximately 1.9% of all adult fractures. A recent registry review in Finland found an annual incidence 15.6 per 100,000 person-years males and 11.5 women. There are several studies which have demonstrated a high proportion diaphyseal ipsilateral occult posterior malleolus fractures, this ranges from 22-92.3%. Recent work by Hendrickx et al has highlighted distal third spiral shaft fracture patterns as...
Abstract We present a specialised layer for generative modeling of LHC events with adversarial networks. use Lorentz boosts, rotations, momentum and energy conservation to build network cell generating 2-body particle decay. This is stacked consecutively in order model two staged decays, respecting the symmetries across decay chain. allow modifications resulting four-vectors higher detector effects. give an evaluation generator quality Higgs into Z bosons, further decaying muon pair each.
Abstract Many particle physics analyses are adopting the concept of vectorised computing, often making them increasingly performant and resource-efficient. While a variety computing steps can be directly, some calculations challenging to implement. One these is analytical neutrino reconstruction which involves fitting that naturally varies between events. We show implementation using graph model. It uses established deep learning software libraries natively portable local external hardware...
Abstract Fast turnaround times for LHC physics analyses are essential scientific success. The ability to quickly perform optimizations and consolidation studies is critical. At the same time, computing demands complexities rising with upcoming data taking periods new technologies, such as deep learning. We present a show-case of HH→bbWW analysis at CMS experiment, where we process 𝒪(1 − 10)TB on 100 threads in few hours. This based columnar NanoAOD format, makes use NumPy ecosystem HEP...
Abstract With the development of web information technology, recommendation systems are widely used in social media networks, news delivery, and shopping platforms. Collaborative filtering (CF) is one main methods systems. In recent years, graph convolutional neural network (GCN) has emerged as hottest research method current system due to its powerful ability learn embedding representations on structures. Although networks have been recognized having significant advantages tasks, proposed...
