Analog decoders are constructed based on interconnecting CMOS Gilbert vector multipliers using transistors operating in the sub-VT region. They are seen as an interesting alternative to digital implementations with a low transistor count and a potential for a very low power consumption. Analog implementation makes the circuit sensitive to mismatch, requiring careful transistor sizing. A simulation
People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application running on the Android platform in which a user may scan for map in
We have developed an electrochemical cell for in situ 2-Dimensional Surface Optical Reflectance (2D-SOR) studies during anodization and cyclic voltammetry. The 2D-SOR signal was recorded from electrodes made of polycrystalline Al, Au(111), and Pt(100) single crystals. The changes can be followed at a video rate acquisition frequency of 200 Hz and demonstrate a strong contrast between oxidizing and
One important element in the interaction between the natural and the human environment is the negative impact of the first on the latter when seen through the prism of urban destabilization. Within this scope, the issue of urban abandonment and disappearance holds an important place, the indirect cause of which are the specifics of local and regional natural subsystems. Small towns are especially
Recent revisions to the diagnostic criteria for Alzheimer’s disease (AD†) incorporated conceptual advances in the field. Specifically, AD is now recognized to encompass a continuum, spanning from preclinical (accruing brain pathology in the absence of symptoms) through symptomatic predementia (prodromal AD, mild cognitive impairment) and dementia phases. The role of biological markers (biomarkers)
Calcitonin gene-related peptide (CGRP) is a 37 amino acid neuropeptide with several functions including vasodilation, the perception of painful stimuli, and inflammation. The CGRP receptor consists of two main components; calcitonin-like receptor (CLR) and receptor activity-modifying protein 1 (RAMP1). While there is a growing recognition that CGRP plays a key role in migraine, the function of CGR
Slotted wing tips of birds are commonly considered an adaptation to improve soaring performance, despite their presence in species that neither soar nor glide. We used particle image velocimetry to measure the airflow around the slotted wing tip of a jackdaw (Corvus monedula) as well as in its wake during unrestrained flight in a wind tunnel. The separated primary feathers produce individual wakes
This paper reports a cross linguistic study that compares the coarticulation patterns between consonant and vowel (CV) in Mandarin Chinese and Southern Swedish. Kinematic data were collected using the Electromagnetic Articulography (EMA) for both languages and were subjected to three types of CV time lag measurement, based on more or less equivalent landmarks on lips and tongue, and partially adop
Forskning inom elektromagnetiska fenomen kan betraktas som en av de viktigaste vetenskapliga fälten, då en betydande del av modern teknologi och infrastruktur bygger på principer som har utvecklats från detta område. Att förstå det fysikaliska ursprunget av magnetiska effekter och deras tillämpningar är av stort intresse inom fasta tillståndets fysik. På senare år har teoretisk forskning förutspAltermagnetism is an emerging field within condensed matter physics. This new magnetic phase was first theoretically considered and later experimentally observed. The physical properties of altermagnets are speculated to make them appealing candidates for applications within fields such as spintronics and superconductivity. To determine which materials exhibit altermagnetism, numerical considerati
Transverse Resonant Island Buckets (TRIBs) is a promising method for pseudo-single bunch delivery in the MAX IV 1.5 GeV storage ring. In this thesis, a theoretical model of the non-linear optics based on resonant Hamiltonian mechanics is applied to the TRIBs optics. Measurement techniques for characterizing the TRIBs orbit are developed and tested and compared with theoretical predictions and nume
