Groundwater accounting is becoming increasingly important for sustainable societal development. To gain insights into the long-term spatiotemporal changes from 1992 to 2015 regarding groundwater resources in Kumamoto, southern Japan, we analyzed climatological time series, discharge from the groundwater-fed lake (Ezu Lake), and groundwater levels from 94 wells. To explicitly detect temporal change

Kungl. Vetenskapsakademien har beslutat dela ut årets ekonomipris till Claudia Goldin (verksam vid Harvard University) ”för att ha förbättrat vår förståelse av kvinnors arbetsmarknadsutfall”. Hon var först med att ge en helhetsbild av kvinnors inkomster och deltagande på arbetsmarknaden genom århundradena. Forskningen belyser drivkrafterna bakom förändringarna och pekar på de huvudsakliga orsakern

One of the major open problems in complexity theory is proving super-logarithmiclower bounds on the depth of circuits (i.e., P⊈NC1). Karchmer et al. (Comput Complex 5(3/4):191–204, 1995) suggested to approach thisproblem by proving that depth complexity behaves “as expected”with respect to the composition of functions f◊g. They showedthat the validity of this conjecture would imply that P⊈NC1.Seve

Radio signals are used broadly as navigation aids, and current and future terrestrial wireless communication systems have properties that make their dual-use for this purpose attractive. Sub-6 GHz carrier frequencies enable widespread coverage for data communication and navigation, but typically offer smaller bandwidths and limited resolution for precise estimation of geometries, particularly in e

We construct a set of Wigner 6j symbols with gluon lines (adjoint representations) in closed form, expressed in terms of similar 6j symbols with quark lines (fundamental representations). Together with these Wigner 6j symbols with quark lines, this gives a set of 6j symbols sufficient for treating QCD color structure for any number of external particles, in or beyond perturbation theory. This faci

Densiteten I stadens utveckling utmanar oss arkitekter till att skapa bra arkitektur i stadsrummet. Staden växer och skapar nya förutsättningar i människans vardag. Staden förtätas och då brist på bra centralt placerad mark blir väldigt påfrestande så skapas nya urbana typologier. Jag vill i mitt examensarbete arbeta vidare på denna problematik och undersöka mer specifikt, hur ser bostaden ut i The density of the city’s development challenges us architects to create good architecture in the urban space. The city grows and creates new conditions in people’s everyday lives. The city is densified and when the lack of good centrally located sites becomes very challenging, new urban typologies are created. In my master thesis, I work further on this problem and investigate more on what hous

The electronic structure of high-quality van der Waals multiferroic CuCrP2S6 crystals was investigated by applying photoelectron spectroscopy methods in combination with DFT analysis. Using X-ray photoelectron and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy at the Cu L2,3 and Cr L2,3 absorption edges, we determine the charge states of ions in the studied compound. Analyzing the

Understanding the growth dynamics of III-V nanowires is crucial to attaining the atomistic control of nanowire growth required for the fabrication of high-quality devices. In situ studies allow us to monitor the individual processes of the cyclic layer-by-layer growth, which permits us to gain more insight into the growth dynamics than using conventional growth studies. Here, we demonstrate how th

This paper examines the local exponential stability (LES) of trajectories for nonlinear systems on Riemannian manifolds. We present necessary and sufficient conditions for LES of a trajectory on a Riemannian manifold by analyzing the complete lift of the system along the given trajectory. These conditions are coordinate-free which reveal fundamental relationships between exponential stability and

One of the most important challenges for modern society is how to feed the world in a sustainable manner. Agriculture is an essential part of food production, but at the same time it has many negative impacts on the environment, through for example pollution, nutrient leaching, and greenhouse gas emissions, and it is a big driver of biodiversity loss. Organic farming is a farming system that in ma

OBJECTIVE: Radical cystectomy (RC) for bladder cancer is associated with an inherent risk of complications and even postoperative mortality. The number of hospitals performing RC has decreased in Sweden over time, and since a formal regional centralization in 2017 cystectomy care is currently provided by nine hospitals. MATERIAL AND METHODS: In the Swedish National Urinary Bladder Cancer Register

Background: Heart failure with reduced ejection fraction (HFrEF) is characterized by ventricular remodeling and impaired myocardial energetics. Left ventricular pressure-volume (PV) loop analysis can be performed noninvasively using cardiovascular magnetic resonance (CMR) imaging to assess cardiac thermodynamic efficiency. Objectives: The aim of the study was to investigate whether noninvasive PV

The JCMS anniversary symposium marking 20 years of normative power provides a prospective intervention into thinking through the rest of the century. The symposium consists of a lead article followed by three responses to this intervention written by scholars who have thought seriously about co-joining normative and power over the past decades. In the lead article Ian Manners (2024) takes the lang

Solid-liquid interfaces are at the heart of a wide variety of phenomena. Their investigation requires experimental techniques with surface sensitivity such scanning probe microscopy and nonlinear optical techniques. In recent years, solid-liquid interfaces have been investigated with a novel approach based on the generation of high frequency acoustic and optical phonons. Due to the sensitivity of

Background: Intraspecific communication is of crucial importance throughout the animal kingdom and may involve a combination of visual, gustatory, olfactory and acoustic cues. Variation in male sex pheromone amount and composition may convey important information to female conspecifics, for instance on species identity or age. However, whether increased male pheromone titres are associated with fi

When acquiring simple three-dimensional (3d) trajectory data it is common to accumulate large coordinate data sets. In order to examine integrity and consistency of object tracking, it is often necessary to rapidly visualise these data. Ordinarily, to achieve this the user must either execute 3d plotting functions in a numerical computing environment or manually inspect data in two dimensions, plo
