This paper investigates a fundamental networking problem in underwater sensor networks: robust and energy-efficient routing. We present an adaptive location-based routing protocol, called hop-by-hop vector-based forwarding (HH-VBF). It uses the notion of "routing vector" (a vector from source to sink) acting as axis pipe", similar based forward (VBF) work P. Xie, J.-H. Cui L. Lao (VBF: Vector-Based Forwarding Protocol for Underwater Sensor Networks. Technical report, UCONN CSE Report:...
BackgroundThe most common fractures in children are torus (buckle) of the wrist. Controversy exists over treatment, which ranges from splint immobilisation and discharge to cast immobilisation, follow-up, repeat imaging. This study compared pain function affected offered a soft bandage immediate with those receiving rigid follow-up as per treating centre protocol.MethodsIn this randomised controlled equivalence trial we included 965 (aged 4–15 years) distal radius fracture 23 hospitals UK....
Underwater Sensor Networks (UWSNs) are significantly different from terrestrial sensor networks in the following aspects: low bandwidth, high latency, node mobility, error probability, and 3-dimensional space. These new features bring many challenges to network protocol design of UWSNs. In this paper, we tackle one fundamental problem UWSNs: robust, scalable, energy efficient routing. We propose vector-based forwarding (VBF), a geographic routing protocol. VBF, path is guided by vector...
Background: The failure rate of anterior cruciate ligament (ACL) reconstruction in children and adolescents is a significant concern. Of the multitude clinical factors that contribute to this risk, delayed maturation graft laxity are potentially related modifiable elements. aim was investigate knee adolescents. ligamentization may be correlated with residual laxity. Methods: A single-center prospective study included skeletally immature patients treated transphyseal ACL using semitendinosus...
<ns4:p>Background With the increasing volume of data collected for advanced analytical and AI applications, storage remains a significant challenge. Despite advancements in technologies, cost maintaining vast datasets continues to grow. Compression techniques have been widely used address this issue, but existing systems primarily rely on single, typically lossless method, which limits adaptability varying characteristics. Methods This paper introduces COMPASS, multiple compression approach...
Purpose Patients who have undergone lower limb surgery require rehabilitation to regain movement and function in the affected leg. Unfortunately, physical can be painful, reducing compliance recovery. This feasibility study aimed demonstrate that immersive virtual reality (IVR) applications provide potential benefits of anxiety reduction pain distraction for children during gait rehabilitation, increased engagement enjoyment, improved perceived walking quality. Methods included 15 aged 11–16...
In recent years, Industrial Control Systems (ICS) have become increasingly exposed to a wide range of cyber-physical attacks, having massive destructive consequences. Security metrics are therefore essential assess and improve their security posture. this paper, we present novel ICS metric based on AND/OR graphs hypergraphs which is able efficiently identify the set critical components measures that should be compromised, with minimum cost (effort) for an attacker, in order disrupt operation...
This paper investigates the personal experiences of hearing adults with signing Deaf parents in their families, school, and society. In order to obtain relevant information, in-depth semi-structured interviews were conducted 10 Cypriot between ages 21 30 years different occupation, sex, educational background. It was found that most participants developed a bicultural identity, undertook interpreter protector role family, interacted well parents, despite lack communication they noted. The...
Cyber-Physical Systems (CPS), such as Water Distribution Networks (WDNs), deploy digital devices to monitor and control the behavior of physical processes. These devices, however, are susceptible cyber attacks, that may alter their functionality, therefore integrity measurements/actions. In practice, industrial systems utilize simple laws, which rely on various sensor measurements algorithms expected operate normally. To reduce impact a potential failure, operators redundant components; this...
Ares is a modular framework, designed to implement dynamic, reconfigurable, fault-tolerant, read/write and strongly consistent distributed shared memory objects. Recent enhancements of the framework have realized efficient implementation large objects, by introducing versioning data striping techniques. In this work, we identify performance bottlenecks Ares's variants utilizing tracing, popular technique for monitoring profiling systems. We then propose optimizations across all versions...
Despite the hype about blockchains and distributed ledgers, formal abstractions of these objects are scarce1. To face this issue, in paper we provide a proper formulation ledger object. In brief, de ne object as sequence records, operations properties that such an should support. Implemen- tation on top multiple (possibly geographically dispersed) computing devices gives rise to contrast centralized object, dis- tribution allows be applied concurrently ledger, introducing challenges...
During the initial phases of COVID-19 pandemic, accurate tracking has proven unfeasible. Initial estimation methods pointed toward case numbers that were much higher than officially reported. In CoronaSurveys project, we have been addressing this issue using open online surveys with indirect reporting. We compare our estimates results a serology study for Spain, obtaining high correlations (R squared 0.89). view, these strongly support idea reporting as method to broadly sense progress pandemic.
Pediatric transphyseal anterior cruciate ligament reconstruction (ACLR) bears several advantages and is widely used. The main concern the risk of growth disturbance. Our purpose was to investigate incidence factors disturbance in skeletally immature patients who underwent ACLR. We hypothesized that this procedure would generate neither clinically relevant limb length discrepancy (LLD) nor axis deviation.This prospective, consecutive, single-center series included primary ACLR using...
The prevalence of childhood asthma and allergies in Cyprus was significantly higher urban compared to rural areas back the year 2000, against a background an overall low (e.g. current wheeze 6.9%) by comparison northern European countries. In this study we aimed assess temporal changes after 8-year interval examine whether any differential have occurred parts island. During academic years 1999-2000 2007-2008, parents 7-8 old children residing same set completed ISAAC core questionnaire....
Atomically consistent memory services provide resiliency in dynamic settings.
In recent years, two distinct electronic voting technologies have been introduced and extensively utilized in election procedures: direct recording systems optical scan (OS) systems. The latter are typically deemed safer, as they inherently provide a voter-verifiable paper trail that enables hand-counted audits recounts rely on voter input. For this reason, OS machines widely deployed the United States. Despite growing popularity of these machines, known to suffer from various security...
Emulating a shared atomic, read/write storage system is fundamental problem in distributed computing. Replicating atomic objects among set of data hosts was the norm for traditional implementations (e.g., [6]) order to guarantee availability and accessibility despite host failures. As replication highly demanding, recent approaches suggested use erasure-codes offer same fault-tolerance while optimizing usage at hosts. Initial works focused on fix To longevity scalability, service should be...
