Published: March 2020

This study investigated the physicochemical, instrumental and bacterial parameters of tilapia fillets subjected to oxygen-scavenger packaging, alone or in combination with UV-C radiation at two doses (0.102 and 0.301 J/cm2), stored at 4 ± 1 °C for 23 days. The oxygen scavenger, both UV-C doses, and the oxygen scavenger combined with UV-C, independently of the dose, extended the shelf life in 5, 6 and 7 days, respectively, by decreasing the bacterial growth rate and the formation of degradation compounds (e.g., TVB-N and ammonia). Oxygen-scavenger packaging, alone or in combination with UV-C at 0.102 J/cm2 and 0.301 J/cm2 showed lower amounts of free amino acids (FAA; 34.39, 34.49 and 34.50 mg L-lysine/kg fish tissue, 3.63, 3.57 and 3.61 mg L- ornithine/kg fish tissue, 27.52, 27.63 and 27.67 mg L-arginine/kg fish tissue), biogenic amines (BA; 3.81, 3.87 and 3.89 mg cadaverine/kg fish tissue, 12.88, 12.91 and 12.86 mg putrescine/kg fish tissue, 2.41, 2.44 and 2.47 mg spermidine/kg fish tissue), redness (2.53, 2.55 and 2.59), yellowness (6.65, 6.69 and 6.72), lipid oxidation (1.52, 1.53 and 1.58 mg malondialdehyde/kg fish tissue) and protein oxidation (5.06, 5.11 and 5.18 nmol carbonyls/mg protein), with higher hardness (3273.41, 2652.98 and 2687.57 g) than control (air packaging; 41.97 mg L-lysine/kg fish tissue, 4.83 mg L- ornithine/kg fish tissue, 37.33 mg L-arginine/kg fish tissue, 4.82 mg cadaverine/kg fish tissue, 16.56 mg putrescine/kg fish tissue, 3.21 mg spermidine/kg fish tissue, 4.26 of redness, 8.17 of yellowness, 2.88 mg malondialdehyde/kg fish tissue, 9.44 nmol carbonyls/mg protein and 2092.58 g of hardness), respectively, on day 13 of storage when the control fillets were unfit for consumption (7 log CFU/g) (p < 0.05). However, in the same day of storage, both UV-C doses had similar values for BA (p > 0.05), higher amounts of FAA (44.28 and 44.13 mg L-lysine/kg fish tissue, 5.16 and 5.12 mg L- ornithine/kg fish tissue, 40.20 and 40.28 mg L-arginine/kg fish tissue), redness (4.86 and 5.33), yellowness (9.32 and 10.01), lipid oxidation (3.09 and 3.52 mg malondialdehyde/kg fish tissue) and protein oxidation (10.27 and 11.93 nmol carbonyls/mg protein), as well as lower hardness (1877.54 and 1767.39 g), respectively, than control fillets (p < 0.05). The combined preservation methods were the most effective in extending the shelf life and prolonging the physicochemical quality of the refrigerated tilapia fillets and the O2 scavenger proved to be a potential alternative to prevent the negative changes induced by both UV-C doses.

Hydrocephalus is a common disorder caused by the buildup of cerebrospinal fluid (CSF) in the brain. Treatment typically involves the surgical implantation of a pressure-regulated silicone tube assembly, known as a shunt. Unfortunately, shunts have extremely high failure rates and diagnosing shunt malfunction is challenging due to a combination of vague symptoms and a lack of a convenient means to monitor flow. Here, we introduce a wireless, wearable device that enables precise measurements of CSF flow, continuously or intermittently, in hospitals, laboratories or even in home settings. The technology exploits measurements of thermal transport through near-surface layers of skin to assess flow, with a soft, flexible, and skin-conformal device that can be constructed using commercially available components. Systematic benchtop studies and numerical simulations highlight all of the key considerations. Measurements on 7 patients establish high levels of functionality, with data that reveal time dependent changes in flow associated with positional and inertial effects on the body. Taken together, the results suggest a significant advance in monitoring capabilities for patients with shunted hydrocephalus, with potential for practical use across a range of settings and circumstances, and additional utility for research purposes in studies of CSF hydrodynamics.

Wolbachia can reduce the capability of mosquitoes to transmit infectious diseases to humans and is currently exploited in campaigns for the control of arboviruses, like dengue and Zika. Under the assumption that Wolbachia-mediated activation of insect immunity plays a role in the reduction of mosquito vectorial capacity, we focused our attention on the Wolbachia surface protein (WSP), a potential inductor of innate immunity. We hypothesized that the heterologous expression of this protein in gut- and tissue-associated symbionts may reduce parasite transmission. We thus engineered the mosquito bacterial symbiont Asaia to express WSP (AsaiaWSP). AsaiaWSP induced activation of the host immune response in Aedes aegypti and Anopheles stephensi mosquitoes, and inhibited the development of the heartworm parasite Dirofilaria immitis in Ae. aegypti. These results consolidate previous evidence on the immune-stimulating property of WSP and make AsaiaWSP worth of further investigations as a potential tool for the control of mosquito-borne diseases.

Published: March 2020

Rapid kinetics, complex and diverse reaction intermediates, and difficult screening make the study of assembly mechanisms of high-nuclearity lanthanide clusters challenging. Here, we synthesize a double-cage dysprosium cluster [Dy60(H2L1)24(OAc)71(O)5(OH)3(H2O)27]·6H2O·6CH3OH·7CH3CN (Dy60) by using a multidentate chelate-coordinated diacylhydrazone ligand. Two Dy30 cages are included in the Dy60 structure, which are connected via an OAc− moiety. The core of Dy60 is composed of 8 triangular Dy3 and 12-fold linear Dy3 units. We further change the alkali added in the reaction system and successfully obtain a single cage-shaped cluster [Dy30(H2L1)12(OAc)36(OH)4(H2O)12]·2OH·10H2O·12CH3OH·13CH3CN (Dy30) with a perfect spherical cavity, which could be considered an intermediate in Dy60 formation. Time-dependent, high-resolution electrospray ionization mass spectrometry (HRESI-MS) is used to track the formation of Dy60. A possible self-assembly mechanism is proposed. We track the formation of Dy30 and the six intermediate fragments are screened.
Topologically protected zero refraction of elastic waves in pseudospin-Hall phononic crystals

Published: March 2020

Zero-angle refraction of elastic waves in metamaterials has attracted attention for its extraordinary wave collimation properties. However, earlier implementations relied on the specific flat equifrequency curve of the phononic crystals suffer from a narrow range of incident angles or operating bandwidths, which severely hinders the exploration and design of functional devices. Here, we propose an elastic near-zero refractive index metamaterial of a triangular lattice to realize topological zero refraction with arbitrary angles of incidence and wide working frequency range. Topological robustness of the zero-angle refraction of pseudospin-Hall edge state against defects is experimentally demonstrated. Furthermore, tunable wave mode conversion associated with the zero-angle refraction is revealed and discussed. These results provide a paradigm for the simultaneous control of the refraction properties of longitudinal and transverse waves that can be employed for designing the topological elastic antennas and elastic wave collimator.

Investigation on linearisation of data‐driven transport research: two representative case studies
Authors: Zou Yun , Kuang Yan , Zhi Yue , Qu Xiaobo
Published: March 2020

Transportation engineering, as a practical engineering discipline, relies heavily on the accurate calibration of importation parameters from field data. In the real world, most transport relations possess inherent non‐linearity. Two prevailing methods for handling non‐linear regression are the non‐linear least‐squares method (LSM) with an iterative solution, and linearisation for the non‐linear regression function. The second method applies a linear regression method to solve the non‐linear regression problem but requires a data transformation of the observations from variant coordinates, and the objective function is suspected to be changed accordingly. This work describes the authors’ investigation into the problem of non‐linear regression through two illustrative examples, the calibration of three non‐linear (either exponential or logarithmic) single‐regime models for fundamental diagram and the regression of non‐linear (power) bunker‐consumption model, by applying the weighted LSM (WLSM) and the ordinary LSM to calibrate. It is found that linearising the regression model leads to deviations, and the data transformation can create even more concern with the WLSM because the weights can be redistributed after the data transformation. A further investigation into the linear regression and the non‐linear regression gives more suggestions on the choice of regression method.

Context. Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordingly, previously ignored systematic effects must be addressed.

Aims. In this work, we evaluate the impact of the reduced shear approximation and magnification bias on information obtained from the angular power spectrum. To first-order, the statistics of reduced shear, a combination of shear and convergence, are taken to be equal to those of shear. However, this approximation can induce a bias in the cosmological parameters that can no longer be neglected. A separate bias arises from the statistics of shear being altered by the preferential selection of galaxies and the dilution of their surface densities in high-magnification regions.

Methods. The corrections for these systematic effects take similar forms, allowing them to be treated together. We calculated the impact of neglecting these effects on the cosmological parameters that would be determined from Euclid, using cosmic shear tomography. To do so, we employed the Fisher matrix formalism, and included the impact of the super-sample covariance. We also demonstrate how the reduced shear correction can be calculated using a lognormal field forward modelling approach.

Results. These effects cause significant biases in Ωm, σ8, ns, ΩDE, w0, and wa of −0.53σ, 0.43σ, −0.34σ, 1.36σ, −0.68σ, and 1.21σ, respectively. We then show that these lensing biases interact with another systematic effect: the intrinsic alignment of galaxies. Accordingly, we have developed the formalism for an intrinsic alignment-enhanced lensing bias correction. Applying this to Euclid, we find that the additional terms introduced by this correction are sub-dominant.

Four different fungicides that recommended to control seed-borne pathogens, were tested in this study. Three fungicides contain singly pyraclostrobin (200 g/L), thiram (400 g/L), fludioxonil (25 g/L), and one fungicide contains together imazalil, metalaxyl, and tebuconazole (50, 40, and 30 g/L, respectively). Comparative assessment of the fungicides at four concentrations of active substance (10, 100, 1 000, and 10 000 ppb) on the growth of ten strains of Fusarium spp. was studied in vitro tests. To visualize the effect of fungicides on fungal growth the strains were cultivated in 50 mL liquid Czapek medium containing fungicides in the range of concentrations. The fungicide based on pyraclostrobin was the most effective in growth inhibition of Fusarium fungi. Broadly, the using of this fungicide is confident way to control Fusarium species, which are serious threat to crop production. The sensitivity of F. acuminatum, F. graminearum, F. semitectum, F. culmorum, F. sporotrichioides, F. equiseti strains to fungicides was higher in compare with the strains belonging to F. oxysporum, F. solani, F. verticillioides, and F. proliferatum.

Authors: Senderskiy Igor , Ignatieva Anastasiya , Dolgikh Viacheslav
Published: March 2020

Microsporidia Vairimorpha (Nosema) ceranae is an emergent parasite of honeybee Apis mellifera and has a great concern to apiculture due to high pathogenesity and fumagillin resistance. Recently RNA interference and single-chain antibodies technologies are proposed to create unsusceptible to intracellular parasites breeds of insects. In this study we established cell culture model system to provide a way to investigate the molecular basis of interactions between honeybee and its pathogen. As the first step in this direction V. ceranae spores were isolated from living bees, properly sterilized and in vitro germinated with Sf9 lepidopteran-derived cell line. The entire life circle of this parasite was achieved. This should allow us to develop the novel treatment strategy directed to inhibit propagation of V. ceranae intracellular stages with recombinant antibodies targeted to the vitally important membrane transporters.

On the development of kink-bands: A case study in the Westasturian-Leonese Zone (Variscan belt, NW Spain)
Authors: Aller Jesús , Bastida Fernando , Bobillo-Ares Nilo C.
Published: March 2020

A field analysis of kink bands developed in slates from three areas (Grandas, Boal and Luarca areas) of the Westasturian-Leonese Zone (Iberian Variscan belt) is presented. The analysis of the main parameters that characterize the geometry of the studied kink bands shows that those of the Grandas and Luarca areas exhibit a different evolution than those of the Boal area. In this latter area, the interlimb angle of the kink bands has lower values than those developed in the former areas and it involves rotation of the foliation inside and outside the band. In the areas with higher bulk shortening associated with the development of kink bands, chevron folds formed by juxtaposition of kink bands. Slip between folia and their rotation was probably the dominant mechanism in the formation of the kink bands, as deduced from the different values of the angle between the kink plane and the foliation inside (φK) and outside (φ) the band, and the occurrence of fractures along the kink planes and small steps between folia cross-cutting these fractures planes. The fractures along the kink planes prevented subsequent hinge migration. Geometrical analysis of kink bands formed by slip between folia and their rotation provides an estimation of the changes in area and thickness, and the strain inside the kink band. For angles of folia rotation ψ < 50°, the ratio between the strain ellipse axes is < 3 inside the band; this ratio is almost independent of the orientation of the kink planes with respect to the foliation outside the band (angle φ).

Modern breeding of sunflower (Helianthus annuus L.), which started 100 years ago, increased the number and the diversity of cultivated forms. In addition, for more than 50 years, wild sunflower and otherHelianthusspecies have been collected in North America where they all originated. Collections of both cultivated and wild forms are maintained in gene banks in many countries where sunflower is an important crop, with some specificity according to the availability of germplasm and to local research and breeding programmes. Cultivated material includes land races, open pollinated varieties, synthetics and inbred lines. The majority of wild accessions are ecotypes of wildHelianthus annuus, but also 52 other species ofHelianthusand a few related genera. The activities of three gene banks, in USA, France and Serbia, are described in detail, supplemented by data from seven other countries. Past and future uses of the genetic resources for environmental adaptation and breeding are discussed in relation to genomic and improved phenotypic knowledge of the cultivated and wild accessions available in the gene banks.

Vegetable oils are the subject of several studies considering their importance as biological properties. Chemical composition of plants oil depends on the plant family in which they were extracted. The study here deals with analysis of chemical composition of the extract obtained from seeds ofMesembryanthemum forsskaliinaturally grown in the region of AlJouf located in the northern part of Saudi Arabia. Examination of anti-oxidant and anti-fungal properties of seeds oil extract was determined. Results showed that this extract contained 23 chemical elements with good amounts of phytosterols (35%). In addition, the antioxidant activity was evaluated by DPPH test which showed good activity and a value of IC50 = 3.43 ± 0.19 mg/mL. For the determination of the antifungal activity, 11 fungal species belonging to 7 genera were isolated from children hairs.Aspergillus carneusandPenicillium chrysogeniumwere the most frequent fungi (32.45, 25.41%), respectively, whereas the appearance ofPenicillium chrysogeniumandFusarium oxysporumwere found to be (17.67 and 12.33%), respectively. Results showed that the percentage of boys infested hair by fungi was higher than that of girls with a percentage 70.85 and 55.62%, respectively. Antifungal activity of ethanolic seeds extract was carried out on the isolated non-dermatophytes keratinophilic fungi. It was found that the fungi ofPenicillium chrysogeniumandAspergillus. fumigatuswere inhibited by seeds oil extract with 88% followed byAspergillus flavus, Aspergillus carneuswith 85% of inhibition and the rest of the isolated fungi were inhibited between 60 and 75%. Based on these encouraging results, seeds oil extract ofM. forskaliican be interesting for food, pharmaceutical or cosmetic industries.

Aims. Our goal is to develop and provide an open end-to-end (Sun to Earth) space weather modeling system, enabling to combine (“couple”) various space weather models in an integrated tool, with the models located either locally or geographically distributed, so as to better understand the challenges in creating such an integrated environment. Methods. The physics-based models are installed on different compute clusters and can be run interactively and remotely and that can be coupled over the internet, using open source “high-level architecture” software, to make complex modeling chains involving models from the Sun to the Earth. Visualization tools have been integrated as “models” that can be coupled to any other integrated model with compatible output. Results. The first operational version of the VSWMC is accessible via the SWE Portal and demonstrates its end-to-end simulation capability. Users interact via the front-end GUI and can interactively run complex coupled simulation models and view and retrieve the output, including standard visualizations, via the GUI. Hence, the VSWMC provides the capability to validate and compare model outputs.

Background Heterotopic pregnancy refers to the simultaneous coexistence
of an intrauterine and extrauterine pregnancy. In natural conception it is very
rare, with a rising incidence in patients undergoing assisted reproduction
technologies. It presents a serious diagnostic problem which is often
misdiagnosed. Currently, there are no standard protocols for the treatment and
diagnosis of heterotopic pregnancy.

Methods Two rare cases of spontaneous heterotopic pregnancy are
presented.

Result The first patient had a complete abortion upon which an
extrauterine pregnancy was detected. The second patient, after an extrauterine
pregnancy removal, progressed with an intrauterine pregnancy until full term and
it ended with the delivery of a healthy infant.

Conclusion Two demonstrated cases underscore that whenever abnormal
adnexal findings are presented and the beta-hCG blood test is positive, the
possibility of a heterotopic pregnancy should be suspected.

Bladder Pain Syndome/Interstitial Cystitis due to Pudendal Nerve Compression: Described in 1915—A Reminder for Treating Pelvic Pain a Century Later
Authors: Gohritz Andreas , Dellon Arnold Lee
Published: March 2020

Background Interstitial cystitis (IC) or bladder pain syndrome (BPS) is highly painful and disabling and probably the most misdiagnosed urologic condition. Its classic symptoms of perineal pain, urinary urgency, and frequency despite sterile urine cultures were already described more than a century ago in a report on soldiers during World War (WW) I due to chronic pudendal nerve compression.

Objectives This article translates a report from 1915 on pudendal neuropathy and discusses its author Georg Zülzer (1870–1949).

Methods An English translation of the German original is provided with the biography and work of Zülzer, his clinical observations are discussed regarding modern diagnosis and therapy of pudendal nerve compression.

Results In his article entitled “Irritation of the Pudendal Nerve (Neuralgia). A Frequent Clinical Picture during War Feigning Bladder Catarrh,” Zülzer describes his observation of soldiers during WW I, presenting with a triad of perineal pain, urinary urgency, and frequency despite sterile urine cultures excluding urinary infections. He also documented a characteristic skin hypersensibility of the perineum in a rhomboid shape which corresponds to the innervation area of the pudendal nerve with its two branches deriving from the “pudendal plexus.” He regards this symptomology as rare during peace, but as disease of trench warfare which can be easily diagnosed regarding clear urine and a painful skin island overlying the area of the pudendal nerve as tested by simple needle examination. Zülzer, born in Germany, was forced to emigrate to the United States in 1934, was also an important pioneer of diabetes research using pancreas extracts from dogs as early as 1907.

Conclusion In this historical description, dating from about a century ago, Georg Zülzer probably gave the first exact clinical description of symptoms due to pudendal nerve compression. Pudendal nerve compression should always be taken into account when examining and treating patients with symptoms of IC/BPS.
The Impact of a Stabilization Exercise on Neck Pain: A Systematic Review and Meta-analysis
Authors: Wu Binbin , Yuan Hongyan , Geng Deyu , Zhang Liang , Zhang Cheng
Published: March 2020

Introduction The efficacy of a stabilization exercise for the relief of neck pain remains controversial. We conducted a systematic review and meta-analysis to explore the effectiveness of a stabilization exercise on neck pain.

Methods We searched Embase, Web of Science, EBSCO Information Services, and the Cochrane Library databases through May 2019 for randomized controlled trials (RCTs) assessing the impact of a stabilization exercise on neck pain. This meta-analysis was performed using the random effects model.

Results Six RCTs are included in the meta-analysis. Compared with the control group of patients with neck pain, a stabilization exercise can significantly reduce pain scores at 4 to 6 weeks (mean difference [MD]: −2.41; 95% confidence interval [CI], −4.46 to −0.35; p = 0.02), Neck Disability Index [NDI] at 10 to 12 weeks (MD:− 6.75; 95% CI, −11.71 to −1.79; p = 0.008), and depression scale at 4 to 6 weeks (MD: −4.65; 95% CI, −7.00 to −2.31; p = 0.02), but it has no obvious impact on pain scores at 10 to 12 weeks (MD: −1.07; 95% CI, −3.42 to 1.28; p = 0.37) or at 6 months (MD: −1.02; 95% CI, −3.43 to 1.39; p = 0.41).

Conclusions A stabilization exercise can provide some benefits to control neck pain.
Volar Scaphoid Plating for Nonunion: A Multicenter Case Series Study
Authors: Eng Kevin , Gill Stephen , Hoy Simon , Shridar Vivek , Van Zyl Natasha , Page Richard
Published: March 2020

Background The volar scaphoid plate from Medartis (Medartis AG, Austrasse, Basel, Switzerland) is a variable angle titanium locking plate, preformed for the volar aspect of the scaphoid. It does not have compressive capability, and may act as a bridging device. It may provide an advantage over a compression screw where the pathoanatomy is less favorable to such a device with increased rotational stability. It may act as a buttress plate for correction of humpback deformity for example. It has been used in nonunions and with vascularized grafts.

Questions Our study aims to assess the results of our patients with scaphoid nonunion treated with scaphoid volar plating over a larger number of patients. We aim to identify techniques to increase the success of plating.

Methods Patients from our cohort were retrospectively reviewed. Operations were performed by three hand fellowship trained surgeons and in two centers. Inclusion involved a scaphoid plate procedure for a nonunion of the scaphoid with a minimum of 6 months of follow-up. Exclusions were those who had less than 6 months of follow-up. Data included demographics, patient-rated wrist evaluation (PRWE), a quick disabilities of the arm, shoulder, and hand (qDASH), visual analogue score, and range and grip. Radiology was reviewed.

Results Thirty-two eligible patients were assessed. The mean age was 25 years (range 13–46), 2 were female and 15 were smokers. Mean follow-up postsurgery was 18 months. Twenty-nine of 32 patients united (90.6%) on computed tomography scan. Clinical assessment was performed in the 25 patients. The mean qDASH score was 12.5 (range 0–42) and mean PRWE was 11 (range 0–54). The mean arc of motion was 115 degrees. The mean grip strength was 39 kg compared with 41 kg on the nonoperated side.

Conclusion We postulate that the plate acts like an internal bridging device, acting over a small distance, and inherent stability of the construct with structural graft and accurate reduction prior to plating is advantageous. Potential problems include plate impingement on the volar lip of the radius, particularly when trying to plate more proximal fractures. Ideally, it is utilized for mid to distal waist fractures.
Deep learning for video compressive sensing
Authors: Qiao Mu , Meng Ziyi , Ma Jiawei , Yuan Xin
Published: March 2020

We investigate deep learning for video compressive sensing within the scope of snapshot compressive imaging (SCI). In video SCI, multiple high-speed frames are modulated by different coding patterns and then a low-speed detector captures the integration of these modulated frames. In this manner, each captured measurement frame incorporates the information of all the coded frames, and reconstruction algorithms are then employed to recover the high-speed video. In this paper, we build a video SCI system using a digital micromirror device and develop both an end-to-end convolutional neural network (E2E-CNN) and a Plug-and-Play (PnP) framework with deep denoising priors to solve the inverse problem. We compare them with the iterative baseline algorithm GAP-TV and the state-of-the-art DeSCI on real data. Given a determined setup, a well-trained E2E-CNN can provide video-rate high-quality reconstruction. The PnP deep denoising method can generate decent results without task-specific pre-training and is faster than conventional iterative algorithms. Considering speed, accuracy, and flexibility, the PnP deep denoising method may serve as a baseline in video SCI reconstruction. To conduct quantitative analysis on these reconstruction algorithms, we further perform a simulation comparison on synthetic data. We hope that this study contributes to the applications of SCI cameras in our daily life.

Its primary aim is to introduce R as a research instrument in quantitative Interactional Linguistics. Focusing on visualization in R, the book presents original case studies on conversational talk-in-interaction based on corpus data and explains in good detail how key graphs in the case studies were programmed in R. It also includes task sections to enable readers to conduct their own research and compute their own visualizations in R. Both the code underlying the key graphs in the case studies and the datasets used in the case studies as well as in the task sections are made available on the book’s companion website.
Towards the successful completion of a doctoral dissertation
Authors: Bitchener John
Published: March 2020

In this chapter, I discuss a number of approaches that my
students have found helpful as they seek to complete their doctoral
dissertation within a reasonable period of time. Some of the ideas presented
here may need to be modified to meet the established protocols and
procedures of both your university and supervisors/advisors preferences. I
divide the doctoral journey into several key stages, including the
pre-enrolment period, the provisional enrolment period, the confirmation of
candidature period, the submission and viva (oral defense) period. Within
these stages, I describe what I consider to be some important activities and
issues to think about so that you know what is expected and are able to
maintain momentum. Some of the ideas that I present may not be ones that you
consider particularly important and that is to be expected as no two
students’ needs and preferred approaches are the same. However, I would
suggest that you give the ideas some consideration as they have been
effective with the students I have supervised.
