Electronic Structures of Free-Standing Nanowires made from Indirect Bandgap Semiconductor Gallium Phosphide

We present a theoretical study of the electronic structures of freestanding nanowires made from gallium phosphide (GaP) - a III-V semiconductor with an indirect bulk bandgap. We consider [001]-oriented GaP nanowires with square and rectangular cross sections, and [111]-oriented GaP nanowires with hexagonal cross sections. Based on tight binding models, both the band structures and wave functions o

The role of executive control in rhythmic timing at different tempi

We investigated the role of attention and executive control in rhythmic timing, using a dual-task paradigm. The main task was a finger tapping task in which participants were asked to tap their index finger in time with metronome sequences. The tempo of the sequences ranged from 600 ms to 3000 ms between each beat. The distractor task, chosen so as to engage executive control processes, was a nove

Modeling of the photoplethysmogram during atrial fibrillation

A phenomenological model for simulating the photoplethysmogram (PPG) during atrial fibrillation (AF) is proposed. The simulated PPG is solely based on RR interval information, and, therefore, any annotated ECG database can be used to model sinus rhythm, AF, or rhythms with premature beats. A PPG pulse is modeled by a linear combination of a log-normal and two Gaussian waveforms. The model PPG is o

Promoting peace in a time of war : Wartime summer camps and the Swedish Scout movement 1939–45

“Be Prepared!” The motto of the Scout movement seemed fitting when the Second World War broke out in 1939. Sweden maintained a state of neutrality during the entire conflict but this period, known generally as the “Time of Preparedness” (beredskapstiden), affected all parts of society. While the diplomatic and political events of these years have been thoroughly covered in Swedish historiography,

Scouting at Home : Family Virtues and Domestic Ideals in the Swedish Scout Movement 1910–1960

This paper examines how organizations for Boy Scouts and Girl Scouts in Sweden dealt with domestic and parental issues, from the movement’s inception in 1910 to 1960. The perspective is twofold. First, it discusses how ideals and expectations concerning participation in domestic matters differed for boys and girls. Were these gender roles stable or changeable? Secondly, it brings to light how pare

Market Solutions

The reliance on market solutions by the Swedish public sector has increased significantly in recent decades. The Swedish example is characterized by an openness to market solutions in many public-sector activities and by a mix of procurement arrangements and choice-based arrangements. The overall experience is that the consequences of the extension of market solutions have been less profound than

Exploring the mechanical strength of additively manufactured metal structures with embedded electrical materials

Ultrasonic Additive Manufacturing (UAM) enables the integration of a wide variety of components into solid metal matrices due to the process induced high degree of metal matrix plastic flow at low bulk temperatures. Exploitation of this phenomenon allows the fabrication of previously unobtainable novel engineered metal matrix components.The feasibility of directly embedding electrical materials wi

The N-terminal Ankyrin Repeat domain is not required for electrophile and heat activation of the purified mosquito TRPA1 receptor

Temperature sensors are crucial for animals to optimize living conditions. The temperature response of the ion channel transient receptor potential A1 (TRPA1) is intriguing; some orthologs have been reported to be activated by cold and others by heat, but the molecular mechanisms responsible for its activation remain elusive. Single-channel electrophysiological recordings of heterologously express

HbA1c as a predictor of diabetes after gestational diabetes mellitus

Aim We wanted to investigate third-trimester HbA1c as a predictor of diabetes after gestational diabetes mellitus (GDM). Methods Women with GDM were followed up prospectively for five years from pregnancy to detect the development of diabetes. The ability of HbA1c to predict diabetes was evaluated with receiver-operating characteristic (ROC) curves and logistic regression analysis. Results By five

Survey shows large differences between the Nordic countries in the use of less invasive surfactant administration

Aim: Less invasive surfactant administration (LISA), namely surfactant instillation through a thin catheter in the trachea during spontaneous breathing, is increasingly used for premature infants. We surveyed the use of this technique in the Nordic countries in autumn 2015. Methods: A link to a web-based survey of surfactant administration methods was emailed to the directors of all neonatal units

Hope Wanted : Wall Writing Protests in Times of Economic Crisis in Athens

This paper discusses the urban writing on Athenian walls as an imaginative medium of intercommunication occurring during the socioeconomic and political crisis era in Greece, over the last seven years. The street art activity on the city’s walls as a linguistic and imagery phenomenon could be approached as the main symbolic mode of public expression generated by the crisis. To investigate it field

Particle Filter Framework for 6D Seam Tracking Under Large External Forces Using 2D Laser Sensors

We provide a framework for 6 DOF pose estimation in seam-tracking applications using particle filtering. The particle filter algorithm developed incorporates measurements from both a 2 DOF laser seam tracker and the robot forward kinematics under an assumed external force. Special attention is paid to modeling of disturbances in the respective measurements, and methods are developed to assist the

The Fundamental Rights Agency and Civil Society: Reminding the gardeners of their plants’ roots

The European Union Agency for Fundamental Rights (FRA), the EU bodyresponsible for advising EU institutions on fundamental rights, is equipped with a Fundamental Rights Platform (FRP) to ensure an on-going and structuredexchange of information and feedback between the FRA and Civil Society. Whenthe FRA was founded in 2007, there was little pre-existing knowledge on how todesign such a Platform; he
