A prerequisite for the design and evaluation of wireless systems is the understanding of propagation channels. While abundant propagation knowledge exists for bands below 6 GHz, the same is not true for millimeter-wave frequencies. In this paper, we present the design, implementation and measurement-based verification of a re-configurable 27.5-29.5 GHz channel sounder. Based on the switched array

Nonintrusive temperature measurement is crucial in combustion research. Here, we propose a thermometric technique based on femtosecond two-photon laser-induced fluorescence of carbon monoxide (CO-fs-TPLIF). A femtosecond laser with a wavelength of 230 nm was used as an excitation source. Owing to its intrinsic broad bandwidth, dual vibrational bands of the B1Σ+ ← X1Σ+ transition of CO can be simul

This short response does two things. First, it argues that urban benchmarks have specific and structural limits not identified in the principal essay in this intervention, which curtail the kinds of constructive and critical work such benchmarks might be expected to perform. ISO 37120 is discussed as an example. Second, it proposes a pluralistic approach to engagement and offers six suggestions fo

In this work, we study the formal connections between the non-linear Fokker-Planck Equation associated with the non-additive entropy and the Boltzmann Equation with the non-additive correlation functional. The collisional term following the q-algebra is adopted. In the derivation of the non-additive Fokker-Planck Equation, two constraints are imposed on the final result: i) that the entropic index

What role should social science play in the work for transforming society towards sustainability? The background for this question is that despite massive investments in environmental research and the accumulation of data on the human impact on the environment, action remains insufficient. The severity of the current situation has led to the conclusion that moderate change is not enough; there is

Organic colloids are an important part of dissolved organic matter (DOM) yet many of their properties remain elusive. The main aims of this study were to assess how the colloidal properties of DOM extracted with water from an organic boreal soil horizon varied with the extraction protocol, and thereby provide insight into the nature of the DOM colloids and develop a mechanistic understanding of ho

Stakeholder involvement in wildlife management is important and requires knowledge about factors motivating such participation. With several goose populations increasing in Europe and goose management incorporating multiple objectives, involvement of stakeholder groups with diverse interests is needed. In this study, we examined how evaluations of geese (attitude and acceptance capacity), but also

We analyze the determinants of firm-based inventors’ collaborations with universities abroad, comparing them with collaborations with national universities. We propose a micro-founded theoretical framework that introduces the role of personal linkages and global organizational pipelines as drivers of international academic collaborations, and we empirically investigate collaborations with national

Acer campestre L. is a rarely silviculturally managed and poorly investigated European tree species which forms seminatural populations and can thus be considered as a model tree for studying post glacial colonisation and phylogeography. Herein, we studied the genetic structure of Acer campestre L. in order to investigate population and genetic diversity clines over the distribution range and for

Aims: To develop and validate sex-specific risk prediction models based on easily obtainable clinical data for predicting 5-year risk of type 2 diabetes (T2D) among individuals with impaired fasting glucose (IFG), and generate practical tools for public use. Methods: The data used for model training and internal validation came from a large prospective cohort (N = 18,384). Two independent cohorts

OBJECTIVES: The aim of this study was to compare readmissions and death between sepsis and non-sepsis hospitalisations the first year after discharge, and to investigate what diagnoses patients with sepsis present with at readmission. The aim was also to evaluate to what degree patients hospitalised for sepsis seek medical attention prior to hospitalisation. DESIGN: Retrospective case-control stud

The long theorized two-dimensional allotrope of SiC has remained elusive amid the exploration of graphenelike honeycomb structured monolayers. It is anticipated to possess a large direct band gap (2.5 eV), ambient stability, and chemical versatility. While sp2 bonding between silicon and carbon is energetically favorable, only disordered nanoflakes have been reported to date. Here we demonstrate l

I propose that the evolution of teaching has been central in extending manipulative intentions. Demonstrating may be the evolutionarily first form of expression that is productive, ostensive, and involves informative intention. Demonstration also involves theory of mind. Then pantomime goes a step further and involves a communicative intention. Pantomime can thereby function as displaced communica

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To evaluate the benefits and harms of stem cell-based interventions for the treatment of stroke in newborn infants compared to control (placebo or no treatment) or stem-cell based interventions of a different type or source.

Recent quasi-two-dimensional (quasi-2D) systems with judicious exploitation of the atomic monolayer or few-layer architecture exhibit unprecedented physical properties that challenge the conventional wisdom on condensed matter physics. Here we show that the infinite layer SrCuO2 (SCO), a topical cuprate Mott insulator in bulk form, can manifest an unexpected metallic state in the quasi-2D limit wh

We report supercurrent transport measurements in hybrid Josephson junctions comprising semiconducting InAs nanowires with epitaxial ferromagnetic insulator EuS and superconducting Al coatings. The wires display a hysteretic superconducting window close to the coercivity, away from zero external magnetic field. Using a multi-interferometer setup, we measure the current-phase relation of multiple ma

Circuit complexity has been used as a tool to study various properties in condensed matter systems, in particular as a way to probe the phase diagram. However, compared with measures based on entanglement, complexity has been found lacking. We show that when imposing penalty factors punishing nonlocality, it becomes a much stronger probe of the phase diagram, able to probe more subtle features. We
