Space, and embodied movement through it, produces place meanings and senses of belonging as individual and environment act upon each other. This co-constitution, however, remains changeable over time with each new or repeated experience. Following an autoethnographic walk around an Italian city, this article charts how passage through and between different parts of the city can evoke often consist
The family Simuliidae includes more than 2000 species of black flies worldwide. Their morphological uniformity creates difficulty for species identification, which limits our knowledge of their ecology and vectorial role. We investigated the systematics of black flies in a semiarid area of the Iberian Peninsula, an ecologically harsh environment for these organisms. Sampling adult black flies in t
The avian magnetic compass can be disrupted by weak narrow-band and broadband radio-frequency (RF) fields in the lower MHz range. However, it is unclear whether disruption of the magnetic compass results from the elimination of the perception pattern produced by the magnetic field or from qualitative changes that make the pattern unrecognizable. We show that zebra finches trained in a 4-arm maze t
Despite the fact that the resolution of conventional contact/proximity lithography can reach feature sizes down to ∼0.5-0.6 micrometers, the accurate control of the linewidth and uniformity becomes already very challenging for gratings with periods in the range of 1-2 μm. This is particularly relevant for the exposure of large areas and wafers thinner than 300 μm. If the wafer or mask surface is n
Transmissibility has increased during the evolution of SARS-CoV-2, possibly by improved airborne transmission. An increased transmission was noted also in many hospitals. We analyzed SARS-CoV-2 in room air of hospitalized Omicron infected patients and compared results with previous findings with pre-Delta variants to study if SARS-CoV-2 was more prevalent in patient rooms after the introduction of
The pluripotency of newly developed human induced pluripotent stem cells (iPSCs) is usually characterized by physiological parameters; i.e., by their ability to maintain the undifferentiated state and to differentiate into derivatives of the 3 germ layers. Nevertheless, a molecular comparison of physiologically normal iPSCs to the "gold standard" of pluripotency, embryonic stem cells (ESCs), often
Almost seven million Ukrainians have fled Ukraine since Russia’s large-scale invasion in February 2022. Seeking refuge in other European states, they were welcomed. However, recent analyses have emerged which point to an increasing discrimination against Ukrainian refugees who were displaced by Russia’s aggression, including in previously supportive nations like Poland. The shifting treatment and
Dwell time is crucial for railway operations, for example, 20% of the total travel time in a mass transit context in the Paris region. With this, it is also a source of delays due to its variability. One way to ensure the robustness of a timetable is to add margins as buffer time that can be consumed to absorb short delays. Much work has been done on run time margins, but dwell time margins receiv
We theoretically investigate a thermoelectric heat engine based on a single-level quantum dot, calculating average quantities such as current, heat current, output power, and efficiency, as well as fluctuations (noise). Our theory is based on a diagrammatic expansion of the memory kernel together with counting statistics, and we investigate the effects of strong interactions and next-to-leading or
INTRODUCTION: Competitive breath-hold divers can accomplish previously unbelievable performances; e.g., the current world record for apnea during rest ("static apnea") is 11 min 35 s. However, whether such performances are associated with a risk for hypoxic brain damage has not been established. CASE REPORT: A breath-hold diver's competitive performance resulted in a loss of consciousness, after w
The Swedish Navy has operated submarines equipped with air independent propulsion for two decades. This type of submarine can stay submerged for periods far longer than other nonnuclear submarines are capable of. The air quality during longer periods of submersion has so far not been thoroughly investigated. This study presents results for a number of air quality parameters obtained during more th
Mps1 kinase plays an evolutionary conserved role in the mitotic spindle checkpoint [1-8]. This system precludes anaphase onset until all chromosomes have successfully attached to spindle microtubules via their kinetochores [9]. Mps1 overexpression in budding yeast is sufficient to trigger a mitotic arrest, which is dependent on the other mitotic. checkpoint components, Bub1, Bub3, Mad1, Mad2, and
Five parkinsonian patients who had received implants of human embryonic mesencephalic tissue unilaterally in the striatum 10-56 months earlier were grafted with tissue from four to eight donors into the putamen (four patients) or the putamen plus the caudate nucleus (one patient) on the other side, and were followed for 18-24 months. After 12-18 months, PET showed a mean 85% increase in 6-L-[18F]f
In a uniform granite gneiss study area in central Zimbabwe, lineaments oriented parallel to the maximum regional compressive stress orientation exhibit the thickest regolith development, while lineaments oriented perpendicular to the maximum compressive stress show the shallowest development of weathered regolith. The principal fracture set orientations were mapped using aerial imagery. The region
Postural adaptability and responses elicited by vibratory stimulation to the calf muscles recorded on a force platform with eyes open or closed were analyzed in 39 patients suffering from Postural Phobic Vertigo (PPV) (17 men and 22 women, mean age 49 years) and 24 healthy subjects (14 men, 10 women, mean age 38 years). The vibration induced increased body sway in both groups, but the adaptation p
This study investigated the ability of Zen meditators and non-meditators to sustain attention during an ongoing task. We hypothesized that meditators (n = 15) would sustain attention more efficiently than non-meditators (n = 19) by responding faster to task stimuli, making fewer commission errors, and reporting fewer interfering thoughts in the sustained attention to response task (SART). Their mo
In recent work on international comparisons of income-related inequalities in health, the concentration index has been used as a measure of health inequality. A drawback of this measure is that it is sensitive to whether it is estimated with respect to health or morbidity. An alternative would be to use the generalized concentration index that is based on absolute rather than relative health diffe
