Connection, isolation and reconnection: Quaternary climatic oscillations and the Andes shaped the phylogeographical patterns of the Patagonian bee Centris cineraria (Apidae)

Abstract The joint effect of the Andes as a geographical barrier and the Quaternary glaciations as promoters of genetic divergence remains virtually unexplored in southern South America. To help fill this knowledge gap, in this study we investigated the demographic history of Centris cineraria, a solitary bee mainly distributed in Patagonia. We used mitochondrial and nuclear markers and performed phylogeographical and dating analyses, adjusted spatio-temporal diffusion and species distribution models, and used Approximate Bayesian Computation to identify likely historical demographic scenarios. Our results revealed that during glacial periods the Andes represented a barrier due to the extent of the ice-sheets and the occurrence of unsuitable habitats, while interglacials allowed for gene flow across the Andes. Secondary contact between previously isolated lineages was evident across at least two low-altitude Andean areas, the northern one being a putative glacial refugium. Our findings also suggest that C. cineraria has persisted in situ in four periglacial refugia located along a north–south transect, congruent with the maximum extent of the ice sheet during the Greatest Patagonian Glaciation. As the first phylogeographical study of Patagonian insects, our work reveals that the interaction between Quaternary climatic oscillations and the Andes as a barrier was the main driver of the spatial and demographic history of C. cineraria.
Dance and the nation: performance, ritual, and politics in Sri Lanka

Around the globe, dances that originate in village, temple, and court rituals have been adapted and transformed to carry secular meanings and serve new national purposes. In stage performances, dance competitions, and festivals worldwide, dance has become an emblem of ethnicity and an index of national identity. But what are the 'backstage' stories of those dances and what have been the consequences for their communities of origin? In Dance and the Nation, Susan A. Reed brings to light the complexities of aesthetic politics in an exploration and analysis of Kandyan dance in Sri Lanka. As the national dance of Sri Lanka, Kandyan dance is identified with the majority Sinhala ethnic group and heavily supported by the state. Derived from an elaborate village ritual performed by men of the hereditary drummer caste, the dance was adopted by the state as a symbol of traditional Sinhala culture in the post-independence period and opened to individuals of all castes. Reed's evocative account traces the history and consequences of this transition from ritual to stage, situating the dance in relation to postcolonial nationalism and ethnic politics and emphasizing the voices and perspectives of the hereditary dancers and of women performers.

Two dimensional barcode-inspired automatic analysis for arrayed microfluidic immunoassays

The usability of many high-throughput lab-on-a-chip devices in point-of-care applications is currently limited by the manual data acquisition and analysis process, which are labor intensive and time consuming. Based on our original design in the biochemical reactions, we proposed here a universal approach to perform automatic, fast, and robust analysis for high-throughput array-based microfluidic immunoassays. Inspired by two-dimensional (2D) barcodes, we incorporated asymmetric function patterns into a microfluidic array. These function patterns provide quantitative information on the characteristic dimensions of the microfluidic array, as well as mark its orientation and origin of coordinates. We used a computer program to perform automatic analysis for a high-throughput antigen/antibody interaction experiment in 10 s, which was more than 500 times faster than conventional manual processing. Our method is broadly applicable to many other microchannel-based immunoassays.
Going Farther Together: The Impact of Social Capital on Sustained Participation in Open Source

Sustained participation by contributors in open-source software is critical to the survival of open-source projects and can provide career advancement benefits to individual contributors. However, not all contributors reap the benefits of open-source participation fully, with prior work showing that women are particularly underrepresented and at higher risk of disengagement. While many barriers to participation in open-source have been documented in the literature, relatively little is known about how the social networks that open-source contributors form impact their chances of long-term engagement. In this paper we report on a mixed-methods empirical study of the role of social capital (i.e., the resources people can gain from their social connections) for sustained participation by women and men in open-source GitHub projects. After combining survival analysis on a large, longitudinal data set with insights derived from a user survey, we confirm that while social capital is beneficial for prolonged engagement for both genders, women are at disadvantage in teams lacking diversity in expertise.
APPARATUS AND METHOD TO METALLIZE, REINFORCE, AND HERMETICALLY SEAL MULTIPLE OPTICAL FIBERS

Apparatus and methods to metallize, reinforce, and hermetically seal multiple optical fibers are described herein. A ribbon of optical fibers may be placed into a fixture to expose a mid-span segment for removal of the coatings from the optical fibers by acid etching, laser, etc. A variety of metallic coatings may then be deposited onto the bare segment of the optical fibers. The metallized segment of optical fibers are then deposited with solderable alloy onto a plate for attachment to the plate for reinforcement of the metallized segment. The plate and metallized segment is then fed through a package opening and hermetically sealed to internally connect one or more components inside the package by heating the package to melt additional solder around the opening or gap. Epoxy is then applied over the solder to help protect the solder and additionally seal the package.
Central European SME Gateway to Key-enabling Technology
Infrastructures - Sparking a new Transnational KET Innovation Ecosystem

CE as model region for an access & service network for SME to bring smart solutions from idea to market readiness Smart solutions derive from applying key enabling technologies (KET) such as micro-nanoelectronics or optical techn. compounds and advanced materials and thus lifting products, processes and services to a new techn. level. SME in food, transport & health are now able to access newest infrastructures, labs & techn. services through regional channels: KET access & service points at business support or applied research organisations in 8 CE regions join forces to act in synergy & across national borders, to ensure that SME are connected & serviced by the best fitting supplier, even if located abroad. Regional access bridges cultural & language barriers. Standard operations but tailored to each single SME ensure reliability & trust.
5 business support organisations from PL, CR, CZ, DE, IT & 3 applied research institutes from AT, HU & SL develop & test the necessary operational models & tools. The Lead Partners research on the EU KET inventory of technol. infrastructures revealed high disparities for available KET services in CE. The project KETGATE will change that, enabling transnational KET techn. collaborations among RTOs to bridge service gaps and enable SME across CE to access high level techn. services. SME can thus test new technol. using innovative machines & laboratories, before they invest in new machines or techn., which may not work for them.
Once validated, collaboration agreements strengthen the KET access & service network. The tools & services, business & collaboration models are available as starter-kits & toolboxes, so that the network can grow towards a KET Innovation Ecosystem, enabling SME to bring smarter solutions quicker to market, levering private and public investments and supporting the dynamic development of KET knowhow & application in CE.
Harmonic Control In Package of Power GaN Transistors for High Efficiency and Wideband Performances in S-Band

This paper presents a method for synthesizing the package of power GaN transistors in order to achieve wideband matching at harmonics. The proposed method is applied to optimize the package of a 15W power GaN HEMT for high efficiency performance over 39% bandwidth (S-band). It is demonstrated that the internal pre-matching of package ensures that the impedance seen by the GaN die at the second-harmonic frequency remains confined inside a high-efficiency region over a wide bandwidth whatever loads presented to the output of the package. In fact, when the 2nd-harmonic frequency termination of the package is varied all over the entire Smith Chart, the packaged transistor demonstrates a limited variation of PAE (70±3)% at 3.2GHz. Thereby, this method allows the designer to synthesize the external output matching of the packaged transistor only at the fundamental frequencies without imposing constraints on the 2nd harmonic loads.
IMPROVED CELLULAR CUSHION VEHICLE SEAT SYSTEM

An improved vehicle seat assembly (20) for mounting on the frame (F) of a vehicle driver's seat (s) including a polymer support plate (22) attached to the frame, a polyurethane foam base (24) on the support, an inflatable air cell cushion (26) on the base and an elastic cover (28). The inflatable air cell cushion (26) includes individual inflation zones (51) each comprised of individual interconnected inflation cells (52). The zones are normally isolated from each other. A center zone (51) having a preset inflation pressure is positioned under the ischial area of the driver. Front, back and side bolster zones provide front-to-back and side-to-side support. The individual air cells (52) of the center zone (51) are interconnected by a serpentine airflow path of reduced area to enhance the vibration and shock absorption characteristics of the zone.
Next generation of mechanics with hazard-responsive surface

80%+ of failures in machines using lubricated moving parts (bearings, gears, camshafts etc.) is due to the damaging operational condition called starved oil lubrication. Recurrent exposure to this state is the bottleneck of performance and durability for such machinery. End-users are happy to pay more for reliable and durable engineering products, but state of the art offers only costly and deficient workarounds to the key peformance-limiting problem.
A disruptive approach to enhance oil lubrication specifically under the critical damaging conditions is recently viable due to high-frequency ultra-short pulse lasers (HFUSPL) having become affordable outside the realm of high-end applications. By using HFUSPLs the micro- and nanoscale patterning of surfaces is possible with unprecedented precision. Such patterning activates a novel and highly effective oil lubricant delivery mechanism expressly under critical contact conditions, resulting in 3x reduction of friction coefficient, improved performance and reliability, reduced maintenance – doubling the lifetime of the entire machinery.
This technology has been advanced to TRL6: real textured engine parts demonstrated in model engines. To make NGenMech available for industry it needs to be automatised using an optoelectric control unit, duly parametrised for the market entry use case, and piloted by a selected industrial partner. To engineer this workplan, a feasibility study will assess potential markets, analyse business model and partnership options, and evaluate commercialisation and IPR strategies to select Primary Use Case and define Strategic Business Plan. As R&D and tech transfer company, IfU Diagnostic Systems GmbH is engaged with several large industrial companies interested in commercialising NGenMech technology.
NGenMech will double the lifetime of machinery while reducing maintenance need. The powerful cascade impact over the entire value chain of mechanical engineering cannot be overestimated.
Strong minimum energy hierarchical topology in wireless sensor networks

Given a set of $$n$$n sensors, the strong minimum energy topology (SMET) problem in a wireless sensor network is to assign transmit powers to all sensors such that (i) the graph induced only using the bi-directional links is connected, that is, there is a path between every pair of sensors, and (ii) the sum of the transmit powers of all the sensors is minimum. This problem is known to be NP-hard. In this paper, we study a special case of the SMET problem, namely , the $$k$$k-strong minimum energy hierarchical topology ($$k$$k-SMEHT) problem. Given a set of $$n$$n sensors and an integer $$k$$k, the $$k$$k-SMEHT problem is to assign transmission powers to all sensors such that (i) the graph induced using only bi-directional links is connected, (ii) at most $$k$$k nodes of the graph induced using only bi-directional links have two or more neighbors, that is they are non-pendant nodes, and (iii) the sum of the transmit powers of all the sensors in $$G$$G is minimum. We show that $$k$$k-SMEHT problem is NP-hard for arbitrary $$k$$k. However, we propose a $$\frac{k+1}{2}$$k+12-approximation algorithm for $$k$$k-SMEHT problem, when $$k$$k is a fixed constant. Finally, we propose a polynomial time algorithm for the $$k$$k-SMEHT problem for $$k=2$$k=2.
Anisotropies in the Gravitational Wave Background from Preheating

We investigate the anisotropies in the gravitational wave (GW) background produced at preheating after inflation. Using lattice field theory simulations of a massless preheating model, we show that the GW amplitude depends sensitively on the value of the decay product field chi coupled to the inflaton phi, with the only requisite that chi is light during inflation. We find a strong anisotropy in the amplitude of the GW background on large angular scales, the details of which strongly depend on the reheating dynamics. We expect similar conclusions for a wide class of inflationary models with light scalar fields. If future direct detection GW experiments are capable of detecting the GW produced by preheating, they should also be able to detect this effect. This could eventually provide a powerful way to distinguish between different inflationary and preheating scenarios.
Futures education: Curriculum and educational practices in Australia, Spain, and Chile

The images of the future among young people have been conditioned by the stories present in the media, films, books, and also in school. Educational curriculums are made up of a selection of knowledge that privileges some ways of understanding the future over others. Young people often imagine a future that is in economic, social, and/or climate crisis. However, they also imagine a bright future for themselves, detached from the future they imagine for society. In this article, we present a qualitative analysis of the curriculums of Australia, Spain, and Chile, together with interviews with teachers from these countries. We investigate the presence and absence of futures education in these curriculums, their degree of development regarding futures education, and make a first analysis of the influence of futures education in schools. To do this we identify four dimensions: situate in time, anticipate, imagine alternative futures, and social action. The results show that, while the Australian curriculum explicitly includes education for the future, the Spanish and Chilean curriculum include it only tangentially. In addition, the socio-cultural context of schools and the will of the teaching staff are elements that determine the implementation of futures education in the school context. Diversos estudios nos indican que las imágenes del futuro que tienen los jóvenes están condicionadas por los relatos presentes en los medios de comunicación, las películas, los libros y también en la escuela. Los currículos educativos incluyen una selección de contenidos que privilegian unas formas de entender el futuro por encima de otras. Los jóvenes suelen representar un futuro en crisis económica, social y/o climática. Sin embargo, estos imaginan para sí mismos un futuro brillante, totalmente desligado del futuro de la sociedad. En este artículo presentamos un análisis cualitativo de carácter descriptivo e interpretativo de los currículos de Australia, España y Chile, junto con entrevistas a docentes de estos países, para estudiar la presencia y ausencia de la educación para el futuro en sus planes de estudios, así como su grado de desarrollo, y hacer un primer análisis de la influencia de la educación para el futuro en las escuelas. Para ello identificamos cuatro dimensiones: situar en el tiempo, anticipar, imaginar futuros alternativos y actuar socialmente. Los resultados muestran que, mientras que el currículo australiano incluye de forma explícita la educación para el futuro, el currículo español y chileno la incluyen solo de forma tangencial. Además, el contexto sociocultural del centro y la voluntad del profesorado son elementos que determinan el desarrollo de la educación para el futuro en la escuela.

Alexandrite and colour-change chrysoberyl from the Lake Manyara alexandrite-emerald deposit in northern Tanzania

Mineralogical and gemmological properties of alexandrite from the Mayoka deposit, Lake Manyara mining area, Tanzania, are described. The alexandrite crystals are located in a phlogopite- bearing schist which is part of a metamorphic-metasomatic association of mafi c or ultramafi c rocks in contact with pegmatitic intrusions. Emeralds are associated with the pegmatites. Single crystals, contact twins, penetration twins and cyclic twins (trillings) are all present in this area and are developed in two major habits, one tabular parallel to the a pinacoid and the other columnar along the a-axis. Microscopic features of faceted and rough alexandrites are characterized by internal growth structures refl ecting the external morphology of the samples. Common mineral inclusions are phlogopite, apatite and zircon. Associated with series of channels parallel to the a-axis three groups of elongated or tabular negative crystals oriented in a plane parallel to the a pinacoid form milky white zones in some samples. The complexity of alexandrite colours is clarifi ed to some extent by correlation of colorimetric parameters with trace element contents and with the orientation of the alexandrites. The designation of samples as alexandrites and a possible distinction from colour-change chrysoberyl is discussed. Alexandrite and green chrysoberyl from Lake Manyara is compared with samples from other occurrences in phlogopite-bearing schist such as the 'classical' alexandrite deposits in the Urals, Russia, and from Novello, Zimbabwe.
Recovering carbon from contaminated matrices by exploiting the nitrogen and sulphur cycles

The objective of the project is to exploit the integration of the carbon, nitrogen and suflur cycles in bioreactors to design optimal treatment trains to recover added-value products out of liquid and gaseous effluents. The strategy will be to combine interdisciplinary approaches to:

- investigate innovative unit processes based on partial nitrification for nitrogen recycle, autotrophic denitrification for biosulfur recovery and multienzyme-based bioreactors for CO2 valorization;
- apply technologies that are novel in this field such as moving bed bioreactors, membrane biofilm reactors and enzimatic reactors
- combine biological processes in to innovative treatment trains for wastewater treatment and biogas upgrading.

The topic will be addressed from the point of view of circular economy by exploring the potential synergies of carbon, nitrogen and sulfur cycles in wastewater and biogas treatment trains to reduce treament costs and to te increase production of added-value products. From a methodological point of view, the project targets the improvement of existing knowledge of innovative technologies based on immobilized biocatalysts as well as the demonstration of the viability of innovative treatment trains at in-silico, lab- and pilot-scale levels. 

The project is interdisciplinary and intersectorial; in fact, the research teams involved include environmental and chemical engineers, biologists and bioinformatics and mathematical modellers, while the companies are complementary being specialised in reactors design and construction and in bioprocess design and control. Finally, the involvement of the industry will allow to receive feedbacks on the solutions needed from pilot case studies using real effluents and to effectively translate novel scientific outcomes into suitable technologies.
Building a 3d innervated and irrigated muscle on a chip.

The aim of the MyoChip project is to build a 3D human skeletal muscle irrigated by vasculature and innervated by neurons. The reconstituted 3D muscle will mirror the architecture and function found in vivo, namely in shape, contractility and microenvironment, while irrigation by a vascular network and innervation by human motor neurons will bring additional physiologic pertinence to it. This organ-on-a-chip technology will have numerous applications including but not limited to research on muscle building and aging, drug testing and screening, as well as prosthetics and biorobotics. The feasibility of the project relies on the interdisciplinary approach which joins a team of cell biologists, material engineers, experts in microfluidics and mathematical modellers. The architecture of skeletal muscle and its regenerative capabilities make muscle a prime candidate to push the 3D tissue engineering field. As such the project will lay the technical, material and methodological foundations to tackle the next generation of complex organ-on-a-chip systems that the MyoChip consortium can exploit for the generation of highly complex 3D in vitro systems of many organs.
