From similarity to uniqueness: Method and theory in comparative psychology
Comparative psychology is a strongly interdisciplinary field that shares many of its experimental methods and observational techniques with ethology and developmental psychology. The great variety of theories that comparative psychology evokes to explain behavior generates a wide array of exciting and potentially fruitful accounts, but is also problematic. It increases the risk of error in the for
Simulation of Fully Developed Laminar Heat and Mass Transfer in Fuel Cell Ducts with Different Cross Sections
The fully developed laminar flow and heat transfer for ducts with rectangular and trapezoidal cross section in fuel cells have been numerically simulated with one porous wall with a uniform mass injection or suction, while the other three walls being impermeable. The new concept of thermal boundary conditions of combined constant heat flux and constant temperature on the walls was implemented. Bas

The Ultra-Wide Bandwidth Indoor Channel - From Statistical Model to Simulations
We establish a statistical model for the ultra-wide bandwidth (UWB) indoor channel based on an extensive measurement campaign in a typical modern office building with 2-ns delay resolution. The approach is based on the investigation of the statistical properties of the multipath profiles measured in different rooms over a finely spaced measurement grid. The analysis leads to the formulation of a s
An Introduction to Control and Scheduling Co-Design
The paper presents the emerging field of integrated control and CPU-time scheduling, where more general scheduling models and methods that better suit the needs of control systems are developed. This creates possibilities for dynamic and flexible integrated control and scheduling frameworks, where the control design methodology takes the availability of computing resources into account during desi

Bridging boundaries between organizations in construction
Organizations have boundaries that serve various purposes; for example, differentiating internal operations from external activities and controlling flows of information. Boundaries can however hinder knowledge exchange in inter‐organizational collaboration, leading to less effective outcomes. Empirical results from comparative case studies on how boundaries between organizations in a project can
Throughput of IEEE 802.11 FHSS networks in the presence of strongly interfering Bluetooth networks
The impact of interference from Bluetooth networks on the throughput of IEEE 802.11 FHSS networks is investigated. This is done by deriving an analytical approximation of the throughput of slow frequency-hopping systems. The derivation in itself provides valuable insights into the mechanisms of interference between systems employing the frequency-hopping technique. In deriving the approximation, i
Evolution from spherical single-particle structure to stable triaxiality at high spins in Nd-140
The level structure of Nd-140(60)80 has been established up to spin 48 by in-beam gamma-ray spectroscopy by use of the Zr-96(Ca-48, 4n) reaction. High-fold gamma-ray coincidences were measured with the EUROBALL spectrometer. Twelve new rotational bands have been discovered at high spins. They are interpreted as being formed in a deep triaxial minimum at epsilon(2) approximate to 0.25 and gamma app

Revisiting the PnP Problem: A Fast, General and Optimal Solution
In this paper, we revisit the classical perspective-n-point (PnP) problem, and propose the first non-iterative O(n) solution that is fast, generally applicable and globally optimal. Our basic idea is to formulate the PnP problem into a functional minimization problem and retrieve all its stationary points by using the Gr¨obner basis technique. The novelty lies in a non-unit quaternion representati

Nature-Based Solutions or Debacles? The Politics of Reflexive Governance for Sustainable and Just Cities
With their potential to effectively address multiple urban sustainability challenges, the emerging policy discourse on nature-based solutions seeks to encourage the development of multifunctional nature for sustainable and just cities. Nature-based solutions, however, are vulnerable to co-option by powerful interests in ways that limit their contribution to a broad range of sustainability goals.

Dexamethasone eye-drops for treatment of retinopathy of prematurity
Both studies on animals and humans have demonstrated the role of inflammatory mediators on the retinopathy process.2,3 Dexamethasone is a glucocorticoid with a known reductive effect on several of these mediators and on the expression of VEGF.4Starting in 2016, infants receiving laser ablation for type 1 ROP at Skåne University Hospital were administered dexamethasone eye-drops postoperatively, us
Dynamic mmWave Channel Emulation in a Cost-Effective MPAC with Dominant-Cluster Concept
Millimeter-Wave (mmWave) massive multiple-input multiple-output (MIMO) has been considered as a key enabler for the fifth-generation (5G) communications. It is essential to design and test mmWave 5G devices under various realisticscenarios since the radio propagation channels pose intrinsic limitations on the performance. This requires emulating realistic dynamic mmWave channels in a reproducible
Law’s Comprehensiveness and Sovereign Leadership : On the Juridico-political Thinking of Ayatollah Khomeini and Carl Schmitt
This essay takes its point of departure in a letter written by Ayatollah Khomeini suggesting that sovereign authority is a matter of “absolute divine guardianship” and that the state “may suspend any matter – be it devotional or non-devotional – when it contravenes the best interests of Islam for the duration that it is so”. Khomeini insistence that the Islamic state headed by a Guardian Jurist is

Insulin regulates Nedd4-2 via a PKB-dependent mechanism in HEI-OC1 auditory cells-crosstalks with sphingolipid and cAMP signaling
BACKGROUND: The mechanisms of association between diabetes and inner ear dysfunction are unknown, although endolymphatic hydrops may be involved. We have previously shown that insulin signaling components are expressed in human saccule and that insulin signaling takes place in HEI-OC1 auditory cells.AIM: To explore Nedd4-2 as a target for insulin signaling.MATERIALS AND METHODS: Effects of insulin
A quantitative LC-MS method to determine surface contamination of antineoplastic drugs by wipe sampling
The main objective was to develop a wipe sampling test to measure surface contamination of the most frequently used antineoplastic drugs (ADs) in Swedish healthcare and, furthermore, to develop an analysis method sensitive enough to assess low levels of contamination. Two wipe sampling tests with separate sample processing methods assessing (i) cyclophosphamide (CP), ifosfamide (IF), 5-fluorouraci
