Non-biomedical Perspectives on Pain and its Prevention and Management
No full textOverreliance on the biomedical paradigm has contributed, in part, to overuse of surgery and long-term drug medication with harmful physical, psychological, social, and economic consequences. Research is dominated by a tissue-centric biomedical view of pain at the expense of a holistic first-person experience of living with pain in communities of people habiting modern-world settings. Pain practice seems overly consumed with the burden of pain at an individual level (patient-centred pain management) and has neglected exploration of societal level (community-centred) or environmental level (ecologically-centred) solutions.
This Research Topic acknowledges that the biomedical paradigm does not provide a complete understanding of pain by focussing attention upstream towards the role of the environment in fashioning the experience and impact of pain on health. Research methodologies from non-biomedical disciplines can explore social, cultural, economic, political, and environmental conditions that influence the living experience of pain in the modern era. Investigating the phenomenon of pain using socio-ecological frameworks provide opportunities to shift perspectives and open-up new avenues for exploration, including innovative strategies to reduce the burden of pain on society.
The purpose of this Research Topic is to broaden and deepen the conceptual understanding of pain in the modern era by showcasing contributions from non-biomedical disciplines. This includes exploration of the concept of painogenic lifestyles and environments, and non-medical strategies[...]”

Computing the 3-Edge-Connected Components of Directed Graphs in Linear Time
No full textLet G be a directed graph with m edges and n vertices. We present a deterministic linear-time algorithm for computing the 3-edge-connected components of G . This is a significant improvement over the previous best bound by Georgiadis et al. [SODA 2023], which is O~(mm−−√) and randomized. Our result is based on a novel characterization of 2-edge cuts in directed graphs and on a new technique that exploits the concept of divergent spanning trees and 2-connectivity-light graphs, and requires a careful modification of the minset-poset technique of Gabow [TALG 2016]. As a side result, our new technique yields also an oracle for providing in constant time a minimum edge-cut for any two vertices that are not 3-edge-connected. The oracle uses space O(n) and can be built in O(mlogn) time: given two query vertices, it determines in constant time whether they are 3-edge-connected, or provides a k-edge cut, with k≤2 , that separates them
Determinants of Human Development: Capturing the Role of Institutions
Get PDFIn this paper, we study development in a panel of 87 countries from 1970 to 2005. We focus on characterizing institutionally driven heterogeneities in the development effects of macroeconomic policies and on comparing the development process as measured by GDP to that measured by the Human Development Index (HDI). We do so within a novel dynamic panel modelling framework that can account for crucial aspects of both the cross-sectional and intertemporal features of the observed process of development, and that can capture the dependence of the development effects of macroeconomic policies on differences in countries’ persistent characteristics, such as their institutions. Among our findings are that macroeconomic policies affect development with less delay than suggested by conventional econometric frameworks, yet impact HDI with longer delay and overall less strongly than GDP. Differences in countries’ persistent characteristics may even affect the sign of the long-run development effects of a given macroeconomic policy: Fiscal stimuli in the form of government consumption expansions positively affect long-run GDP in countries with low institutional quality, but negatively affect long-run GDP in countries with high institutional quality.human development, institutions, dynamic panel modelling

HL in major workers of <i>C. nodus</i> reaches up to 3.5 mm (less than 2.3 mm in <i>C. aphrodite</i>). The overall small body size was already noticed by Forel (1904), who recorded <i>C. nodus</i> from Cyprus and pointed out that a smaller size characterizes Cypriot populations compared to typical <i>C. nodus</i>. Also, the setation of mesosoma, if present, is in <i>C. nodus</i> more abundant and longer than in <i>C. aphrodite</i>. In <i>C. nodus</i>, the longest setae on pronotum are 0.269 mm, on mesonotum 0.230 mm, and propodeum 0.262 mm, while in <i>C. aphrodite</i> 0.158, 0.076, and 0.079, respectively. Currently, there are four taxa considered junior synonyms of <i>C. nodus,</i> and two of them were described from the Eastern Mediterranean region. <i>Cataglyphis bicolor rufiventris</i> Emery, 1925 was described from Korfu [Corfu/ Kerkyra] based on differences in the coloration of gaster, while <i>Cataglyphis viatica orientalis</i> (Forel, 1895) was described from Edirne in Türkiye based on the thicker and lower petiole. In both cases, the characters mentioned above were proven to fall within the infraspecific variation observed in <i>C. nodus</i>. Thus, due to the lack of any name that can be used for the Cypriot populations, we decided to describe them as new to science.</p> <p> <i>Cataglyphis aphrodite</i> might also be confused with some other species of the <i>bicolor</i> species group known from the Eastern Mediterranean. <i>Cataglyphis machmal</i> Radchenko & Arakelian, 1991 differs in the dorsum of mesosoma and first gastral tergite with numerous white, long erect setae, mostly longer than apical width of hind tibia (in <i>C. aphrodite</i> dorsum of mesosoma and first gastral tergite without erect setae or with 1–3 short setae on each mesosomal tergite and at most 6 setae on propodeum, setae never longer than apical width of hind tibia); <i>Cataglyphis oasium</i> Menozzi, 1932 differs in a strongly convex propodeum, legs always dark colored (brown to black) and larger size (HL in major workers always above 3 mm while in <i>C. aphrodite</i> HL <2.5 mm); <i>Cataglyphis israelensis</i> Ionescu & Eyer, 2016 differs in larger body size (HL in major workers up to 3.20 mm) and mesonotum raised over pronotum in most workers; <i>Cataglyphis laevior</i> Emery, 1925 differs in larger body size (HL in major workers always above 3 mm) and less sculptured gaster with shiny lateral sides (in <i>C. aphrodite</i> gaster is more sculptured and never shiny). Also, <i>C. laevior</i> is distributed in northern Africa and its records from Türkiye (Kiran & Karaman 2021) and Arabian Peninsula (Collingwood 1985, Collingwood & Agosti 1996) need confirmation.</p> <p> <b>Description.</b> Major worker (n=8): <i>Measurements.</i> HL: 2.211 (2.07–2.33); HW: 1.999 (1.80–2.17); SL: 2.245 (2.14–2.31); EL: 0.543 (0.51–0.58); PW: 1.385 (1.27–1.48); PRL: 1.184 (1.10–1.28); PRW: 0.991 (0.92–1.07); PTH: 0.460 (0.33–0.55); PTW: 0.484 (0.45–0.54); WL: 3.160 (3.00–3.33); HFL: 3.391 (3.17–3.63); CI: 1.107 (1.064 –1.239); SI: 1.125 (1.064 –1.239); PI: 0.951 (0.880 –1.021); FI: 1.074 (1.032 –1.132).</p> <p> <i>Color.</i> Head, mesosoma, petiole, legs, and antennae red, gaster black (Figs. 11, 12).

We have examined the syntype of <i>Leptothorax bulgaricus cypridis</i> preserved in the Basel Museum (AntWeb.org, CASENT0912914) and numerous specimens from Cyprus conspecific with the syntype. In our opinion, this taxon represents a distinct species, which differs well from <i>Temnothorax bulgaricus</i> (Forel, 1892) in a shorter setation of body. In <i>T. bulgaricus,</i> erect setae on the head, mesosoma, and gaster are very long, the longest setae on mesosoma are longer than the eye diameter while in <i>T. cypridis</i> dorsal setae of mesosoma are short, distinctly shorter than the eye diameter (mean ratio length of setae/eye diameter 0.71, in <i>T. bulgaricus</i> 1.06). The third member of the <i>T. bulgaricus</i> group known from the Eastern part of the Mediterranean Basin, <i>T. nadigi</i> (Kutter, 1925), differs in distinctly bicolored body, with a head predominantly distinctly darker colored than mesosoma, from yellowish-brown to dark brown. Other Cypriot species of <i>Temnothorax</i> well differ from <i>T. cypridis</i> in uniformly yellow antennae and usually well-marked propodeal spines. Only <i>T. aeolius</i> has an antennal club similarly darkened, partly brown to black, but differs in well-marked propodeal spine with mean PSL/HW 0.266 (in <i>T. cypridis</i> the spine is reduced to very small, triangular tubercle or spine with mean PSL/HW 0.225), shorter petiole with mean PI 1.481 (in <i>T. cypridis</i> 1.505), and in more globular petiolar node, without lateral carinae.</p> <p> <b>Redescription.</b> Worker (n = 10): HL: 0.563 –0.706 (0.643); HW: 0.444 –0.589 (0.530); SL: 0.429 –0.540 (0.475); EL: 0.114 –0.151 (0.143); EW: 0.087 –0.115 (0.105); PNW: 0.294 –0.413 (0.367); WL: 0.635 –0.860 (0.763); PEL: 0.225 –0.341 (0.294); PEH: 0.160 –0.238 (0.195); PPL: 0.163 –0.238 (0.217); PPW: 0.175 –0.240 (0.211); PSL: 0.090 –0.139 (0.117); CI: 1.170 –1.268 (1.216); EI1: 1.313 –1.469 (1.368); EI2: 0.202 –0.233 (0.223); SI1: 0.868 – 0.966 (0.897); SI2: 0.693 –0.765 (0.738); MI: 2.000 –2.160 (2.081); PI: 1.406 –1.589 (1.505); PPI: 0.890 –1.074 (0.978); PSLI: 0.179 –0.262 (0.225).</p> <p> <b>Color.</b> Almost whole body yellow, gena usually more or less infuscate, yellowish-brown to brown, antennal club predominantly brown to almost black, first gastral tergite in basal ⅔ length yellow and in posterior ⅓ length with brown band, only posterior margin yellow. Legs uniformly yellow, femora never infuscate in the middle (Figs 19, 20). In the palest specimens band on first gastral tergite very narrow, occupying only ⅕–¼ length of the tergite, in the darkest specimens almost whole posterior half of first gastral tergite is darkened. <b>Head.</b> Slightly elongate, approximately 1.2 × as long as wide, subparallel or gena softly converging anterad and sides behind eyes slightly converging posterad, occipital corners broadly rounded, occipital margin of head straight (Fig. 22). Anterior margin of clypeus softly convex, without central angulation, with 4–6 short setae, medial notch absent. Eyes moderate, elongate, 1.3–1.5 × as long as wide, 0.22 × as long as head length. Antennal scape long, in lateral view slightly curved, approximately 0.9 × as long as width of the head, in apex gradually widened with softly marked preapical constriction, its base with obtuse dorsal and ventral angle. Funiculus distinctly longer than scape, first segment 2.3 × as long as wide at apex, 4.5 × as long as second segment, segments 2–6 transverse, segment 7 only slightly wider than long, club large, 1.2 × as long as segments 1–8 combined, last segment of club elongate, 1.4 × as long as segments 8 and 9 combined (Fig. 22).

Myelin-specific signal extraction from SAXS-TT data
No full textThis software, that also includes a demo dataset, pertains to manuscript “Nanostructure-specific X-ray tomography reveals myelin levels, integrity and axon orientations in mouse and human nervous tissue”, by Georgiadis et al., 2021, Nature Communications
It is intended to demonstrate a central feature of the study, namely the myelin-specific signal extraction from the semi-raw data -that is, after the scattering pattern for each point has been turned into q-plots for the different azimuthal segments (see Fig. 1a,b in the manuscript).
For more details on the file structure of the “Demo” folder, instructions for running the code, requirements and dependencies and an example output figure with its subparts explained can be found in the Readme.pdf file.
