Universals and diversity in gesture
Authors: Cooperrider Kensy 
Published: October 2020

Abstract
At the dawn of anthropology, gesture was widely considered a “universal language”. In the 20th century, however,
this framing fell out of favor as anthropologists rejected universalism in favor of relativism. These polemical positions were
largely fueled by high-flying rhetoric and second-hand report; researchers had neither the data nor the conceptual frameworks to
stake out substantive positions. Today we have much more data, but our frameworks remain underdeveloped and often implicit. Here,
I outline several emerging conceptual tools that help us make sense of universals and diversity in gesture. I then sketch the
state of our knowledge about a handful of gestural phenomena, further developing these conceptual tools on the way. This brief
survey underscores a clear conclusion: gesture is unmistakably similar around the world while also being broadly diverse. Our task
ahead is to put polemics aside and explore this duality systematically – and soon, before gestural diversity dwindles further.
What is an anthropology of gesture?
Authors: Lempert Michael 
Published: October 2020

AbstractFor gesture research outside anthropology, the promise – and challenge – of anthropological method stems from one or more of its core commitments: its pursuit of human variation, both diachronic and synchronic; its insistence on naturalistic rather than experimental research design; and its integrative sensibility that situates human behavior in relation to an expansive sociocultural context. This essay reflects on this last sensibility. As we envision an anthropology of gesture and weigh its potential for gesture studies, we should pause and reflect on the fitful history of gesture in anthropology. As a parable for the present, I revisit a neglected anthropological voice from twentieth-century gesture research: Ray L. Birdwhistell, whose ambitious postwar science of kinesics teamed film-based microanalysis with American linguistic structuralism. At stake in Birdwhistell’s work was a problem that looms large here, that of how and at what cost a science of gesture can contextualize its object integratively.
Body-directed gesture and expressions of social difference in Chachi and Afro-Ecuadorian discourse
Authors: Floyd Simeon 
Published: October 2020

Abstract
This paper presents an analysis of a data set consisting of instances of body-directed gesture that occurred in racializing expressions of social difference during ethnographic interviews with two neighboring peoples of Ecuador: the indigenous Chachi, speakers of the Cha’palaa language, and Afro-Descendant people, who speak a variety of Spanish. When talking about differences among social groups and categories, a particular sub-type of body-directed gestural practice was salient: using indexical-iconic self-directed gestures as a way to describe other people’s physical bodies or appearances, including references to skin color, hair texture, clothing and ornamentation, and embodiments of carrying objects close to the body. The paper describes the trends seen in the forms and meanings of these gestures in their role here as part of socially categorizing and racializing discourses in the Latin American socio-historical context.
Space as space and space as grammar
Authors: Haviland John B. 
Published: October 2020

Abstract
Research on narratives in an Australian language demonstrated surprising facts about speakers’ spatial orientation and knowledge both in the insistent use of morphologically hypertrophied spoken directional terminology and in accompanying gestures. Pursuing comparable phenomena in a Mayan language from the other side of the globe revealed correspondingly complex gestural devices for communicating about location and direction but with very different kinds of support from speech. Evidence from a new sign language, emerging in the same Mayan context, suggests that mechanisms for signing about space both resemble and depart from the gestural practices of the surrounding speech community. In particular, they invoke spatial “frames of reference” not used by speakers to sign about location and direction, and they employ signed “spatial grammar” to express syntactic argument structure.
Embodying kin-based respect in speech, sign, and gesture
Authors: Green Jennifer 
Published: October 2020

AbstractIn Australian Indigenous societies the means for demonstrating kinship-based respect are rich and varied, and mastery of their ideological and contextual dimensions is highly valued and an indication of communicative expertise. Special speech registers, sometimes referred to as ‘mother-in-law’, ‘brother-in-law’, or ‘avoidance’ languages, are one aspect of this complexity. Another dimension of respect is afforded by Australian Indigenous sign languages, used in contexts where speech itself is disallowed as well as in everyday interactions where signing is practical and useful. What is lacking from the majority of accounts of these special semiotic repertoires is an investigation of the ways that speech and communicative actions, such as sign or gesture, may work together in such contexts. Also neglected is the possibility that the articulation of signs and gestures may be modified to indicate a respectful stance towards avoided kin. Drawing on both archival sources and recent fieldwork, this paper delineates some of the articulatory dimensions of signs and gestures used in this domain.

The EURAMET.M.FF-S10 comparison, also registered as EURAMET project 1325, was organized to compare the results of low gas flow facilities at twelve European laboratories. The following laboratories took part in the comparison: MIKES (Finland), INRIM (Italy), PTB (Germany), FORCE (Denmark), METAS (Switzerland), VSL (Netherlands), EIM (Greece), UL (Slovenia), CMI (Czech Republic), LNE (France), GUM (Poland), LEI (Lithuania).
Due to the high amount of participants, the comparison was carried out in two parallel loops with one circulating transfer standard in each loop. MIKES acted as the pilot laboratory and INRIM and PTB were the linking laboratories. High-accuracy piston provers (MesaLabs DryCal 800) provided by Mesa Laboratories Inc. were used as transfer standards. Each transfer standard package consisted of three flow cells in order to cover the flow range of the comparison from 5 ml/min to 30 l/min.
Generally, a good agreement between participating laboratories was found; 85% of the results agree with the comparison reference value and only 8% were found inconsistent. The remaining 7% of results were classified as inconclusive, because the participating laboratory stated uncertainty was lower than the standard uncertainty of the transfer standard.
The comparison provided valuable experience of using piston provers as high precision transfer standards. Such an extensive inter-comparison using piston provers has not been done before. As such, it gives a good overview on the capabilities of European laboratories of calibrating such instruments that are commonly used in industrial calibration laboratories worldwide.

Localized dynamics following a quantum quench in a non-integrable system: an example on the sawtooth ladder
Authors: Khare Rishabh , Choudhury Sayan 
Published: October 2020

Abstract
Motivated by the recent discovery of ergodicity breaking in geometrically frustrated systems, we study the quench dynamics of interacting hardcore bosons on a sawtooth ladder. We identify a set of initial states for which this system exhibits characteristic signatures of localization like initial state memory retention and slow growth of entanglement entropy for a wide parameter regime. Remarkably, this localization persists even when the many-body spectrum is thermalizing. We argue that the localized dynamics originates from an interaction induced quantum interference. Our results show that the sawtooth ladder can be a fertile platform for realizing non-equilibrium quantum states of matter.

Published: October 2020

Abstract
Three-dimensional (3D) high-temperature Hall sensors are strongly required in various applications such as in the automotive and aircraft engines and in the diagnostic system of the thermonuclear reactors. In this paper, we propose a novel Hall sensor based on the wide-bandgap GaN-based materials on a single chip with greatly reduced area which can simultaneously detect 3D magnetic fields at high temperature up to 650 K. The device is analysed and demonstrated by performing the technology computer-aided design simulations, and significantly improved performances are achieved by employing space isolation and passivation scheme to effectively reduce the carrier interference from each dimension. Finally, high current-related magnetic sensitivities are found and the typical values are 128.6, 88.1, and 49.9 V A−1 T−1 on x, y and z axes, respectively, at room temperature. And the temperature coefficients are as low as −286.4, −366.8, and −202.9 ppm K−1, respectively. Moreover, dramatically improved cross-sensitivities are revealed and the maximum value is less than 1.0% at B ≤ 1.0 T which is much lower compared with other currently reported data. The work provides a new technical approach to realize a single-chip 3D magnetic sensor which is promising especially for high-temperature applications.
Glassy dynamics of a binary Voronoi fluid: a mode-coupling analysis
Authors: Ruscher C , Ciarella S , Luo C , Janssen L M C , Farago J , Baschnagel J 
Published: October 2020

Abstract
The binary Voronoi mixture is a fluid model whose interactions are derived from the Voronoi–Laguerre tessellation of the configurations of the system. The resulting interactions are local and many-body. Here we perform molecular-dynamics (MD) simulations of an equimolar mixture that is weakly polydisperse and additive. For the first time we study the structural relaxation of this mixture in the supercooled-liquid regime. From the simulations we determine the time- and temperature-dependent coherent and incoherent scattering functions for a large range of wave vectors, as well as the mean-square displacements of both particle species. We perform a detailed analysis of the dynamics by comparing the MD results with the first-principles-based idealized mode-coupling theory (MCT). To this end, we employ two approaches: fits to the asymptotic predictions of the theory, and fit-parameter-free binary MCT calculations based on static-structure-factor input from the simulations. We find that many-body interactions of the Voronoi mixture do not lead to strong qualitative differences relative to similar analyses carried out for simple liquids with pair-wise interactions. For instance, the fits give an exponent parameter λ ≈ 0.746 comparable to typical values found for simple liquids, the wavevector dependence of the Kohlrausch relaxation time is in good qualitative agreement with literature results for polydisperse hard spheres, and the MCT calculations based on static input overestimate the critical temperature, albeit only by a factor of about 1.2. This overestimation appears to be weak relative to other well-studied supercooled-liquid models such as the binary Kob–Andersen Lennard-Jones mixture. Overall, the agreement between MCT and simulation suggests that it is possible to predict several microscopic dynamic properties with qualitative, and in some cases near-quantitative, accuracy based solely on static two-point structural correlations, even though the system itself is inherently governed by many-body interactions.
Domain structure evolution in the ferromagnetic Kagome-lattice Weyl semimetal Co3Sn2S2

Published: October 2020

Abstract
Co3Sn2S2, a Weyl semimetal that consists of layers of Kagome lattices, undergoes a transition from a high temperature paramagnetic phase to a low temperature ferromagnetic phase below 177 K. The phase transition occurs through an intermediate non-trivial magnetic phase, the so called ‘A’-phase just below the Curie temperature. The ‘A’-phase was earlier linked with a competing anti-ferromagnetic phase, a spin-glass phase and certain indirect measurements indicated the possibility of magnetic Skyrmions in this phase. We have imaged the magnetic domain structure in a single crystal of Co3Sn2S2 at different temperatures, magnetic fields and field-angles by magnetic force microscopy. At low temperatures, we observed stripe domains indicating presence of uniaxial anisotropy. Above 130 K, the domain walls become mobile and they tend to align relatively easily when the magnetic field is increased along the c-axis than in the a–b plane. Our detailed study of field-dependent domain evolution reveal that the anomalous phase below T
c through which the transition happens is most probably governed by domain wall motion.
Resonant inelastic x-ray spectroscopy on UO2 as a test case for actinide materials

Published: October 2020

Abstract
Resonant inelastic x-ray spectroscopy at the uranium N4 absorption edge at 778 eV has been used to reveal the excitations in UO2 up to 1 eV. The earlier (1989) studies by neutron inelastic scattering of the crystal-field states within the 3H4 multiplet are confirmed. In addition, the first excited state of the 3F2 multiplet at ∼520 meV has been established, and there is a weak signal corresponding to the next excited state at ∼920 meV. This represents a successful application of soft x-ray spectroscopy to an actinide sample, and resolves an open question in UO2 that has been discussed for 50 years. The technique is described and important caveats are drawn about possible future applications.
Percutaneous structural cardiology: are anaesthesiologists properly protected from ionising radiation?
Authors: Sánchez Roberto M , Vano Eliseo , Fidalgo Juan , Fernández José Miguel 
Published: October 2020

Abstract
During transcatheter aortic valve implantations (TAVI) and other percutaneous structural procedures, some patients may need close anesthesiological care, thus exposing the anaesthesiologist to x-rays. This work aims to investigate the radiation dose received by anaesthesiologists during these specific procedures in order to improve their radiological protection. Occupational radiation doses were measured prospectively during percutaneous structural procedures in several health professionals using electronic dosimeters worn over the apron at chest level. A sample of 49 procedures were recorded, where the anaesthesiologists’ average dose per procedure resulted 13 times higher than that of interventional cardiologists. The average dose per procedure received over the protection apron during TAVIs by the anaesthesiologist was 0.13 mSv, with a maximum value of 0.69 mSv. Taking these figures as a conservative estimation of the eye lens dose, an anaesthesiologist could participate in around 150 procedures before reaching the regulatory annual dose limit for the lens of the eye in Europe (20 mSv). In those clinical procedures where patients need close anesthesiological care, the anaesthesiologists might receive high radiation doses increasing the risk for cataracts and the risk of stochastic radiation effects. The proper use of occupational dosimeters will help identify these situations. It is recommended to use a mobile shielding barrier to reduce radiation exposure to acceptable levels in these situations.
3D shape measurement of shiny surfaces based on optimized combination of fringe patterns of different intensity

Published: October 2020

Abstract
Image saturation is a challenging problem for three-dimensional shape measurement of objects with shiny surfaces using fringe projection profilometry technology. This paper presents a new method based on projection of multiple fringe patterns, providing an effective solution to the problem. First, a set of phase shifted sinusoidal fringe patterns with different intensity levels are projected to the object of interest, and the reflections are captured by the camera. With the captured images a set of masks are created, which are able to pick up the unsaturated data from the captured images. The unsaturated data are then combined based on maximal Signal-to-noise Ratio (SNR) scenario, and the combined images are used to retrieve the phase information. Comparing to existing methods, the proposed technique is advantageous by improved measurement accuracy due to the improved SNR. The performance of the proposed method is verified by the experiments.
Phase transformation and its effect on the piezopotential in a bent zinc oxide nanowire
Authors: Zhang Jin 
Published: October 2020

Abstract
Most piezotronic nanodevices rely on the piezopotential generated by the bending of their component piezoelectric nanowires (NWs). The mechanical behaviours and piezopotential properties of zinc oxide (ZnO) NWs under lateral bending are investigated in this paper by using a multiscale modelling technique combining first-principles calculations, molecular dynamics simulations and finite-element calculations. Two phase transformation processes are successively found in ZnO NWs by increasing the bending force. As a result, the inner and outer surfaces of bent ZnO NWs transform from the parent wurtzite (WZ) structure to a hexagonal (HX) structure and a body-centred-tetragonal (BCT-4) structure, respectively. Different material properties are found among the WZ, BCT-4, and HX structures, which result in a significant change in the piezopotential distribution in bent ZnO NWs after the phase transformation. Meanwhile, the piezopotential generated in bent ZnO NWs can be enhanced by an order of magnitude due to the phase transformation. Moreover, a significant increase in the electronic band gap is found in the transformed HX structure, which implies that the phase transformation may also affect the piezopotential in bent ZnO NWs by modifying their semiconducting properties especially when the doping level of NWs is large.
Strong surface magnetic field generation in relativistic short pulse laser–plasma interaction with an applied seed magnetic field
Authors: Weichman K , Robinson A P L , Murakami M , Arefiev A V 
Published: October 2020

Abstract
While plasma often behaves diamagnetically, we demonstrate that the laser irradiation of a thin opaque target with an embedded target-transverse seed magnetic field B
seed can trigger the generation of an order-of-magnitude stronger magnetic field with opposite sign at the target surface. Strong surface field generation occurs when the laser pulse is relativistically intense and results from the currents associated with the cyclotron rotation of laser-heated electrons transiting through the target and the compensating current of cold electrons. We derive a predictive scaling for this surface field generation, B
gen ∼ −2πB
seedΔx/λ
0 (in the large spot size limit), where Δx is the target thickness and λ
0 is the laser wavelength, and conduct 1D and 2D particle-in-cell simulations to confirm its applicability over a wide range of conditions. We additionally demonstrate that both the seed and surface-generated magnetic fields can have a strong impact on application-relevant plasma dynamics, for example substantially altering the overall expansion and ion acceleration from a μm-thick laser-irradiated target with a kilotesla-level seed magnetic field.
Dual-band terahertz switch with stretchable Bloch-mode metasurface

Published: October 2020

Abstract
A polydimethylsiloxane (PDMS)-based stretchable metadevice for dual-band switching of terahertz radiation is experimentally demonstrated. The metasurface can efficiently excite dipole resonance of the metal structure and the surface Bloch mode generated by the periodic lattice substrate. In the tensile deformation operation, these two resonant modes show significant frequency shift sensitivity characteristics, which provides a feasible solution for the realization of dual-band terahertz switches. A transmittance modulation depth of 90% is achieved by the dipole resonance, with a frequency shift of 0.14 THz. The other transmittance modulation depth of 65% is achieved by the surface Bloch mode, with a frequency shift of 0.4 THz. The broad tuning of 0.4 THz is attributed to the surface mode is period-sensitive. This approach provides a promising method for broad frequency tuning of stretchable metasurfaces.
