Complementary feedback control enables effective gaze stabilization in animals
Authors: Cellini Benjamin , Salem Wael , Mongeau Jean-Michel 
Published: May 2022

Significance
In visually active animals, eye, head, and body movements are coordinated to direct gaze. Given their distinct mechanics, how does the nervous system weight their contribution? By combining experiments in flying flies with control theory, we show that flies implement an elegant solution to this problem: the lower inertia head is recruited for higher-frequency visual tasks and is sensitive to motion acceleration, whereas the higher inertia body is recruited for lower-frequency visual tasks and is sensitive to motion velocity. This complementary division of labor within the nervous system exhibits two hallmarks of optimality: an increase in task performance accompanied with a decrease in mechanical energy expenditure. Our model recapitulates classic primate head-eye coordination responses, suggesting convergent mechanisms across phyla.
Caused accompanied motion constructions in Vera’a
Authors: Schnell Stefan 
Published: May 2022

Abstract
The expression of bring and take events (so-called ‘caused accompanied motion (CAM)’ events) in the Oceanic language Vera’a (North Vanuatu) is analysed in terms of lexical and constructional compositionality. The two lexical verbs centrally involved in CAM expressions have fairly general semantic content not specific to CAM events, meaning ‘move sth.’ and ‘accompany’. These are used in constructional frames with dative and locative prepositions, serialization with verbs of motion, and directional adverbs and particles. Such constructions can then yield a CAM reading. However, they can also receive a non-CAM reading, so that the verbalisation of CAM events is ultimately a matter of pragmatic inference in Vera’a and never unambiguously encoded. Different verbs are used to specify manner of handling themes, and manner of motion as well as direction can be incorporated in motion verbs in initial position of verb serialization (satellite-framed).
Expressions of directed caused accompanied motion in Komnzo
Authors: Döhler Christian 
Published: May 2022

Abstract
This chapter describes and analyses the expression of directed caused accompanied motion (directed CAM) in Komnzo, a language of Southern New Guinea. The chapter focusses on the interaction between lexical semantics and verb morphology. It shows that the expression of CAM events revolves around a handful of very frequent lexical items (carry, fetch, return verbs), which can be placed in different morphological templates. Morphological fluidity provides a productive mechanism to derive causative alternations of intransitive motion verbs, i.e. an intransitive return verb can be used to express ‘return something’. The chapter adopts a corpus linguistic approach to the phenomenon of CAM events by providing a fine-grained frequency analysis of the most important verb lexemes based on the Komnzo text corpus. Additionally, the chapter describes how the system of adverbial demonstratives and case markers contribute to expression of CAM events.
Maximizing the rate sensitivity of resonating gyroscopes using nonlinear shape optimization
Authors: Polunin Pavel M , Shaw Steven W 
Published: May 2022

Abstract
In this work we demonstrate how one can improve the angular rate sensitivity of ring/disk resonating gyroscopes by tailoring their nonlinear behavior by systematic shaping of the gyroscope body and electrodes, and by the tuning of bias voltages on segmented electrodes. Of specific interest are the drive and sense mode Duffing nonlinearities, which limit their dynamic ranges, and the intermodal dispersive coupling between these modes that provides parametric amplification of the sense mode output signal. These two effects have the same physical origins and are in competition in terms of system performance, which naturally calls for optimization considerations. The present analysis is based on a systematic modeling of the nonlinear response of these devices by which we explore ways in which one can optimize the angular rate sensitivity by manipulating the mechanical and electrostatic contributions to the nonlinearities. In particular, non-uniform modifications of the gyroscope body thickness are employed to affect the mechanical contributions to these parameters, while the electrostatic components are manipulated via shaping of the resonator-electrode gap and by applying non-uniform bias voltages among segmented electrodes around the gyroscope body. These models predict that such relatively simple alterations can achieve improvements in gain by about an order of magnitude when compared to devices with uniform layouts.
γ–α phase transition of elemental cerium metal
Authors: Eryigit Serpil , Parlak Cihan , Eryigit Resul 
Published: May 2022

Abstract
The isostructural γ–α phase transition in elemental cerium has been the subject of many experimental and theoretical studies over almost the past century without a universally agreed upon mechanism. Here, we report the results of an extensive study of electronic and magnetic structures, f-electron number, entanglement entropy, and elastic properties of cerium in the GGA + U framework. We have found that almost all changes in the studied quantities mimic their behavior in the phase transition and could be related to the symmetry of the 4f occupation and the small change in Hubbard U near a critical value.

Abstract
In response to changing international recommendations and national requirements, a number of assessment approaches, and associated tools and models, have been developed over the last circa 20 years to assess radiological risk to wildlife. In this paper, we summarise international intercomparison exercises and scenario applications of available radiological assessment models for wildlife to aid future model users and those such as regulators who interpret assessments. Through our studies, we have assessed the fitness for purpose of various models and tools, identified the major sources of uncertainty and made recommendations on how the models and tools can best be applied to suit the purposes of an assessment. We conclude that the commonly used tiered or graded assessment tools are generally fit for purpose for conducting screening-level assessments of radiological impacts to wildlife. Radiological protection of the environment (or wildlife) is still a relatively new development within the overall system of radiation protection and environmental assessment approaches are continuing to develop. Given that some new/developing approaches differ considerably from the more established models/tools and there is an increasing international interest in developing approaches that support the effective regulation of multiple stressors (including radiation), we recommend the continuation of coordinated international programmes for model development, intercomparison and scenario testing.

Published: May 2022

Abstract
Herein we describe an effective route for the degradation of methyl green (MG) dye under visible light illumination by pristine and strontium (Sr)-doped zinc oxide (ZnO) photocatalysts (synthesized by the simple chemical precipitation method). The x-ray diffraction structural analysis has confirmed that both photocatalysts exhibit the hexagonal wurtzite structure; without any additional phase formation in Sr-doped ZnO, in particular. The optical properties of the synthesized photocatalysts have been investigated using UV–vis absorption spectroscopy in the wavelength range of 250–800 nm. Through Tauc’s plot, the slight decrease from 3.3 to 3.2 eV in band gap energy has been elucidated (in the case of Sr-doped ZnO), which has been further confirmed by the quenching in the intensity of Photoluminescence (PL) emission spectrum. This may be due to sub-band level formation between valence and conduction band, caused by the impregnation of Sr2+ ions into ZnO host. The morphological study has also been performed using Field Emission Scanning Electron Microscope, which indicates nanoparticles (NPs) based surface texture for both photocatalysts. During the photocatalytic activity study, after 30 min irradiation of visible light, ∼65.7% and ∼84.8% photocatalytic degradation of MG dye has been achieved for pristine and Sr-doped (2 wt%) ZnO photocatalysts, respectively. The rate of photocatalytic reaction (K) has been observed to be ∼0.06399 min−1 for Sr-doped (2 wt%), whereas nearly half magnitude ∼0.03403 min−1 has been observed for pristine ZnO, respectively. The significantly improved photodegradation activity may be ascribed to the relatively broader optical absorption capability, surface defects and the enhanced charge separation efficiency of the Sr-doped ZnO photocatalyst.
2D spin transport through graphene-MnBi2Te4 heterojunction
Authors: Chen Xi , Lin Zheng-Zhe 
Published: May 2022

Abstract
The development of two-dimensional (2D) magnetic semiconductors promotes the study of nonvolatile control of magnetoelectric nanodevices. MnBi2Te4 is the first realization of antiferromagnetic topological insulator. In semiconductor circuits, metal-semiconductor contacts are usually essential. In future all-carbon circuits, graphene is a promising material for 2D conductive connections. This work studies electronic transport through graphene-MnBi2Te4-graphene junctions. We find that graphene-MnBi2Te4 interfaces are perfect Ohmic contacts, which benefits the use of MnBi2Te4 in carbon circuits. The currents through MnBi2Te4 junctions possess high spin polarization. Compared with usual van der Waals junctions, lateral graphene-MnBi2Te4-graphene junctions present a lower barrier and much higher conductance to electrons. These findings may provide guidance for further study of 2D spin filtering.

Published: May 2022

Abstract
The compositional and structural engineering of advanced nanomaterials for hydrogen evolution reaction (HER) is highly necessary for efficient hydrogen production. Herein, PdOs nanospine assemblies (PdOs NAs) with urchin-like structures are fabricated via one-step route using DM-970 and KBr as surfactant agent and capping agent, respectively. Benefiting from electronic effect and multi-branched structure, the PdOs NAs exhibit superior performance for HER in alkaline and neutral solutions, requiring overpotentials of 28 and 35 mV at −10 mA cm−2, respectively, as well as superior long-term stability. This study offers a universal approach for the fabrication of active Pd-based catalysts with multi-branched morphology for efficient water electrolysis and beyond.
Compressive sampling system based on random demodulation for active and passive structural health monitoring

Published: May 2022

Abstract
Structural health monitoring (SHM) is a revolutionary and innovative technique for determining structural integrity. It has broad application prospects in industrial equipment and infrastructure such as aircrafts, bridges and buildings. SHM system is used to monitor and diagnose the damages of these large structures, and it requires to install large sensor networks in or on large structures such as aircraft wings and airframes. The large number of sensors results in a very large amount of data for excited and received signals, especially for ultrasonic guided wave-based SHM with high frequency signals. According to the traditional Nyquist sampling theorem, the sampling rate is at least 2 times higher than the highest frequency of the received signal. The high sampling rate and the large amount of data pose a serious challenge on the signal acquisition, transmission, storage, and processing equipment, especially in the case that the signal needs to be transmitted to the base station for processing in real time. Therefore, how to compress and sample signals obtained by large sensor networks to improve monitoring efficiency and reduce costs is a research hotspot in current SHM. This paper adopts compressive sensing (CS) theory which has appeared in recent years to solve the big data and high frequency acquirement problem of SHM. The random demodulation system is chosen to realize CS, and the corresponding hardware and software systems are designed, which are achieved to compress and sample signal and reduce the sampling rate and the amount of data at the same time. The active and passive SHM signals based on piezoelectric sensor networks are compressed and sampled, and the new method are compared with the traditional Nyquist sampling in the experiment. The results show the effectiveness of the proposed method.

Published: May 2022

Abstract
Stingless bees are social bees distributed in Indonesia, including West Halmahera. However, they are not widely known for their value for human health, their role as pollinators, and how to cultivate them. West Halmahera has potencies to develop stingless bees due to its supportive agricultural environment. The aims of this research were to know the community perception of meliponiculture development and to analyze its economic potencies. Community perception analysis (scoring by Likert scale) used purposive sampling for nine respondents who are cultivating stingless bees in their locations based on the suitability analysis. Economic analysis used BEP, R/C Ratio, and ROI. The results showed that he respondents had common knowledge about the bees but less capability to cultivate (55.56%). Ecosystem suitability in West Halmahera was in the high category (66.67%). Most farmers were in full support of the development of the stingless bees for improving the additional family income and it will increase the crops production. The economic analysis showed that initiating business on this insect was quite reasonable because the BEP was < Production (0.33), BEP price < selling price, so the farmers would get significant benefits from this enterprise, with ROI being 215% and R/C ratio >1.

Published: May 2022

Abstract
The main goal of broiler breeders management is producing fertilized egg that can be hatched and to generate hatching eggs that will result in saleable chicks. The purpose of this research was to evaluate the effects supplementation of Nutricell HyC® (combination of 25OHD3 and vitamin C) with various levels on the fertility of broiler breeders. This research used 6,158 female broiler breeders with Cobb strain which were distributed according to a completely randomized design into four experimental treatments, with five replicates of ± 308 birds each. The treatments were Nutricell HyC® supplementation with the levels of 0, 100, 200, and 400 g/ton feed. Parameters observed were the clear eggs, fertile eggs, infertile eggs, culling chicks and early embryo mortality. Data collected were processed using analysis of variance (ANOVA) and for comparing among different group means continued with the Duncan multiple range test. The results showed that Nutricell HyC® supplementation could reduce clear eggs compared to the control diet (P<0.05). Furthermore, the percentages of fertile eggs increased as the level of Nutricell HyC® (P<0.05). However, infertile eggs, culling chicks, early embryo mortality were not affected by the Nutricell HyC® supplementation. The conclusion of this research was suplementation of Nutricell HyC® 400 g/ton feed yielded the best fertility performance of broiler breeders.

Abstract
Phytase is the most common enzyme used in broiler diet mainly to improve phosphorus (P) digestibility and reduce P excretion to environment, but its effectiveness together with other enzymes such as xylanase, amylase and protease (XAP) is not widely evaluated. Current study was conducted to evaluate the efficacy of Buttiauxella spp. phytase supplementation at 1000 FTU/kg alone and its combination with XAP (2000 U/kg xylanase, 200 U/kg amylase and 4000 U/kg protease) on broiler performance and bone mineralization. A total 2849 male broilers Lohmann Indian River (LIR) were randomly assigned to 7 treatments with 11 replications. Treatments were positive control (PC) using standard diet followed LIR recommendation, negative control 1 (NC1) with nutrient reduction of 0.19% units available P, 0.2% units calcium (Ca), 0.41% units crude protein (CP) and 69 kcal/kg AME, NC2 applied similar reduction except for AME which was 105 kcal/kg, and on top of NCs was phytase and/or XAP supplementation. NC1 and NC2 significantly (P<0.05) reduced body weight, mortality-corrected feed conversion ratio (McFCR) and toe ash percentage compared to PC. Phytase alone on top of NCs significantly (P<0.05) improved body weight, McFCR and toe ash percentage. Further, combination of phytase with XAP numerically showed better weight gain, McFCR and broiler index (BI). These data suggest phytase and/or XAP supplementation is effective to maintain broiler performance and toe ash under nutrient deficiency, this because enzymes able to reduce the anti-nutritional effect and lead to better nutrient digestibility.

AbstractThe oryzomyine rodent Euryzoryzomys russatus is endemic to the Atlantic Forest of South America, where it inhabits mostly pristine humid forests. Previous phylogeographical studies performed with limited sample sizes indicated that rivers and climatic oscillations might have driven the diversification of this species. Here, we used a more comprehensive database to revisit the phylogeography and demographic history of E. russatus. Our phylogenetic inferences and haplotype network recovered four groups within E. russatus, each of which diversified between 0.33 and 0.60 Mya. These groups are mostly allopatric and are structured latitudinally along the Atlantic Forest. We did not detect any genetic break related to the major river drainages. Species distribution models recovered similar suitable areas for E. russatus in the present and past times, suggesting stability in the geographical range during the Pleistocene. The most pronounced change was the expansion of suitable areas onto the emerged continental shelf during the Last Glacial Maximum. Demographic analyses showed evidence of population expansion during periods of lowered seal levels, especially for the haplogroup associated with the Serra do Mar forest refuge. Therefore, our results failed to support the hypothesis of riverine barriers and suggest that the diversification of E. russatus is explained better by forest refugial processes.

Published: May 2022

AbstractGray matter volume and thickness reductions have been reported in patients with spinocerebellar ataxia type 3 (SCA3), whereas cortical gyrification alterations of this disease remain largely unexplored. Using local gyrification index (LGI) and fractional anisotropy (FA) from structural and diffusion MRI data, this study investigated the cortical gyrification alterations as well as their relationship with white matter microstructural abnormalities in patients with SCA3 (n = 61) compared with healthy controls (n = 69). We found widespread reductions in cortical LGI and white matter FA in patients with SCA3 and that changes in these 2 features were also coupled. In the patient group, the LGI of the left middle frontal gyrus, bilateral insula, and superior temporal gyrus was negatively correlated with the severity of depressive symptoms, and the FA of a cluster in the left cerebellum was negatively correlated with the Scale for the Assessment and Rating of Ataxia scores. Our findings suggest that the gyrification abnormalities observed in this study may account for the clinical heterogeneity in SCA3 and are likely to be mediated by the underlying white matter microstructural abnormalities of this disease.

Abstract

Background
Patients with bacteremia due to carbapenem-resistant Enterobacterales (CRE) experience delays until appropriate therapy and high mortality rates. Rapid molecular diagnostics for carbapenemases and new β-lactam/β-lactamase inhibitors may improve outcomes.

Methods
We conducted an observational study of patients with CRE bacteremia from 2016 to 2018 at 8 New York and New Jersey medical centers and assessed center-specific clinical microbiology practices. We compared time to receipt of active antimicrobial therapy and mortality between patients whose positive blood cultures underwent rapid molecular testing for the Klebsiella pneumoniae carbapenemase (KPC) gene (blaKPC) and patients whose cultures did not undergo this test. CRE isolates underwent antimicrobial susceptibility testing by broth microdilution and carbapenemase profiling by whole-genome sequencing. We also assessed outcomes when ceftazidime-avibactam and polymyxins were used as targeted therapies.

Results
Of 137 patients with CRE bacteremia, 89 (65%) had a KPC-producing organism. Patients whose blood cultures underwent blaKPC PCR testing (n = 51) had shorter time until receipt of active therapy (median: 24 vs 50 hours; P = .009) compared with other patients (n = 86) and decreased 14-day (16% vs 37%; P = .007) and 30-day (24% vs 47%; P = .007) mortality. blaKPC PCR testing was associated with decreased 30-day mortality (adjusted odds ratio: .37; 95% CI: .16–.84) in an adjusted model. The 30-day mortality rate was 10% with ceftazidime-avibactam monotherapy and 31% with polymyxin monotherapy (P = .08).

Conclusions
In a KPC-endemic area, blaKPC PCR testing of positive blood cultures was associated with decreased time until appropriate therapy and decreased mortality for CRE bacteremia, and ceftazidime-avibactam is a reasonable first-line therapy for these infections.
