A Virtualized LoRa Testbed and Experimental Results for Resource Pooling

Traditional network architecture design of Low Power Wide Area Networks (LPWAN) is incapable of dynamically scaling resources based on the served traffic and requires manual procedures for network capacity upgrades. Today's over-provisioning approach based on proprietary hardware (HW) would not be cost and energy efficient to cope with the ever-increasing scale of Internet of Things (IoT) devices

Ramification structures for quotients of the Grigorchuk groups

Groups associated to surfaces isogenous to a higher product of curves can be characterized by a purely group-theoretic condition, which is the existence of the so-called ramification structure. In this paper, we prove that infinitely many quotients of the Grigorchuk groups admit ramification structures. This gives the first explicit infinite family of 3-generated finite 2-groups with ramification

Spectrum Arguments, Indeterminacy, and Value Superiority

Larry Temkin has forcefully argued for the possibility that the value comparative “better than” is not transitive and that the betterness relation can be cyclical. Temkin uses so-called spectrum arguments to argue that the belief that “better than” is transitive is incompatible with other beliefs that are more intuitive, so we should conclude that “better than” is not transitive. I will argue that

A thermo-viscoplasticity model for metals over wide temperature ranges- application to case hardening steel

In this contribution, a model for the thermomechanically coupled behaviour of case hardening steel is introduced with application to 16MnCr5 (1.7131). The model is based on a decomposition of the free energy into a thermo-elastic and a plastic part. Associated viscoplasticity, in terms of a temperature-depenent Perzyna-type power law, in combination with an isotropic von Mises yield function takes

Incommensurable Values

Values, such as liberty and equality, are sometimes said to be incommensurable in the sense that their value cannot be reduced to a common measure. And options, such as studying to become a lawyer or studying to become a philosopher, are sometimes said to be incomparable in the sense that neither option seems to be at least as good as the other. These possibilities are thought to raise deep questi

Designing virtual natural environments for older adults in residential care facilities

BACKGROUND: Spending time in natural environments is beneficial for mental health and cognitive function. Unfortunately, many elderly citizens, who would potentially gain from these beneficial effects, have limited or no access to natural environments. Virtual reality may provide the experience of being present in a natural environment without the need of transportation. OBJECTIVE: The purpose of

Modern project management : Challenges for the future

In this chapter, the authors highlight that the challenges related to managing modern projects are that the management problems have changed since traditional project management methods were developed. This calls for new project management methods, adapted to situations of rapid technological change and flexibility. The authors identify and highlight the limitations of both traditional and agile m

Faster Dual Lattice Attacks for Solving LWE with Applications to CRYSTALS

Cryptosystems based on the learning with errors (LWE) problem are assigned a security level that relates to the cost of generic algorithms for solving the LWE problem. This includes at least the so-called primal and dual lattice attacks. In this paper, we present an improvement of the dual lattice attack using an idea that can be traced back to work by Bleichenbacher. We present an improved distin

Lower vitamin D is associated with metabolic syndrome and insulin resistance in systemic lupus : Data from an international inception cohort

Objectives: Vitamin D (25(OH)D) deficiency and metabolic syndrome (MetS) may both contribute to increased cardiovascular risk in SLE. We aimed to examine the association of demographic factors, SLE phenotype, therapy and vitamin D levels with MetS and insulin resistance. Methods: The Systemic Lupus International Collaborating Clinics (SLICC) enrolled patients recently diagnosed with SLE (<15 month

Botanical aspects of the agricultural economy at Uppåkra and surrounding settlements

The comprehensive prehistoric settlement Uppåkra, lasting over a millennium,raises questions on how food supplies and local communities were agricultu­rally organized. Recent investigations of archaeobotanical remains from theregional center Uppåkra and several surrounding settlements have contribu­ted to new aspects of their agricultural relations. New patterns in consump­tion show that through i

What is Known About Burns in East Africa? A Scoping Review

Background: Burns are a global public health concern, with the majority of the disease burden affecting low- and middle-income countries. Yet, as suggested by previous publications, there is a widespread belief that literature about burns in low- and middle-income countries is lacking. Therefore, we aimed to assess with a scoping review, the extent of the literature output on burns in East Africa,

Finding a fair deal : Policies on alcohol and drugs at “wet” eldercare facilities

“Wet” eldercare facilities for people who age with long-term substance use problems and complex needs exist in several countries. Residents are accepted as active users of alcohol and drugs, and while the media has presented the permissive policies of the facilities in a positive light, others have described these policies as harmful. The aim of this article is to analyze residents' and staff memb

Thermal history of the southern Central Cordillera and its exhumation record in the Cenozoic deposits of the Upper Magdalena Valley, Colombia

The roughly 600 km long Central Cordillera of Colombia shows a varied tectonic, magmatic, and exhumation history, despite the reasonably homogenous appearance concerning topography, outcropping lithologies, and strike. Here we show with new geo-thermochronological data the thermal evolution of the southern Central Cordillera since the Early Jurassic. Extensive Jurassic magmatism is recorded by U–P

Iron Age emmer and spelt: Where, when and why? : A review of archaeobotanical evidence from southern Sweden, c. AD 1–600

The general outline of the long-term history of cereal cultivation in southern Sweden is relatively well known from published compilations of archaeobotanical data (Hjelmqvist 1955; Engelmark 1992; Gustafsson 1998; Viklund 1998; Grabowski 2011). These compilations show emmer (Triticum dicoccum) and naked barley (Hordeum vulgare var. nudum) as the principal crops of the Neolithic and the Early Bron

Health care utilization prior to suicide in adults with drug use disorders

Drug use disorders (DUD) are associated with psychiatric illness and increased risks of suicide. We examined health care utilization prior to suicide in adults with DUD, which may reveal opportunities to prevent suicide in this high-risk population. A national cohort study was conducted of all 6,947,191 adults in Sweden, including 166,682 (2.4%) with DUD, who were followed up for suicide during 20

Data driven orthogonal basis selection for functional data analysis

Functional data analysis is typically performed in two steps: first, functionally representing discrete observations, and then applying functional methods, such as the functional principal component analysis, to the so-represented data. While the initial choice of a functional representation may have a significant impact on the second phase of the analysis, this issue has not gained much attention

Physical characterization of copper oxide nanowire fabricated via magnetic-field assisted thermal oxidation

Magnetic fields can alter the growth of nanomaterials and, in some cases, ultimately lead to room temperature ferromagnetism (RTF). One promising approach for the growth of nanomaterials is thermal oxidation with both academic and industrial relevance. In this study, we evaluate the growth of copper oxide (CuO) nanowires by thermal oxidation method in a furnace adapted with a static magnetic field
