A complete thermally induced intermartensitic transformation has already been observed in a single crystalline Ni52Mn24Ga24 sample with martensitic transformation temperature (Ms) near room temperature.As constrast with the single crystalline sample,polycrystalline samples,even those annealed ones,did not show this intermartensitic transformation.The experimental results indicates that the intermartensitic transformation can be suppressed by mechanically grinding the single crystalline sample to smaller sizes.This has been attributed to the internal stress and serious lattice distortion caused by the grinding process.The intermartensitic transformation might be suppressed by the elastic energy stored in distorted lattice.As the evidence,grinding the sample to 50μm,the martensitic transformation was even disappeared in the present measurements.Based on this point,the uncompleted intermartensitic transformation observed in the previous works can be explained.

Published: December 2020

This paper researches Fock state space structure and supersymmetry mechanics of parasystem consisting of one degree of freedom of paraboson and one degree of freedom parafermion in the case of the same order p.It is shown that except for the four extreme special states,there is an intrinsic double-degeneracy in the state space structure of a parasystem.Moreover,it is also discovered that the parasystem possesses a hidden intrinsic supersymmetry in addition to the dynamic supersymmetry,and the intrinsic supersymmetry plays a key role in the exact supersymmetry of a parasystem.

Published: December 2020

In this paper,the influence of weak parameter periodic perturbation on the safe basin of a nonlinear oscillator is studied.The results show that the fractal erosion of the safe basin is enhanced when the system is perturbed by the periodic signal at some definite frequencies.On the other hand,the fractal erosion basin is suppressed by the periodic perturbation at other frequencies,for this case there exists an optimal perturbation frequency.Furthermore,based on the obtained results,a method used to control the fractal erosion basin is presented.Melnikov's method is used to interpret this control method,and the robustness of the control of the fractal erosion basin is also discussed.

Using the Gaussian correlation model of random surfaces, we conduct the theoretical derivation of the image-plane intensity produced by a weak scatterer in the 4f optical filtering system.Then the method is proposed for characterizing the square-root-mean deviation roughness and lateral correlation length.This method uses the derived theoretical expressions to fit the experimentally measured curve of image speckle intensity versus the radius of filtering aperture,and the two surface parameters can be extracted simultaneously.In the experiment,random surface samples are specially made and their surface parameters are measured. The results conforms with those obtained by atomic force microscopy,which shows that the method of this paper is of good accuracy.

Published: December 2020

The propagation and switching of short optical pulses in a three-core nonlinear fiber coupler have been investigated with a variation method within the framework of the Lagrangian density formulation.The analytical solutions were directly obtained from the coupled nonlinear Schr?dinger equations.It is shown that the soliton switching behavior predicted by the present analytical method agrees well with the results from numerical analysis.In addition,the coupling length and the switching threshold of solitons in a nonlinear coupler were obtained.
A PHENOMENOLOGICAL DISCUSSION ABOUT FERROELECTRIC PHASE TRANSITION
Authors: AI SHU-TAO  , WANG CHUN-LEI  , ZHONG WEI-LIE  , ZHANG PEI-LIN  ,   山东大学物理系,济南250100
Published: December 2020

The irreversibility of ferroelectric phase transition has been studied by using irreversible thermodynamics.Heat stagnation of the first-order ferroelectric phase transition and polydomain configuration of ferroelectrics can be explained on the basis of the principle of minimum entropy production.A conclusion has been derived that the heat stagnation is not an intrinsic property of a system in which a first-order ferroelectric phase transition arises.The finiteness of the system's surface is connected with the heat stagnation.

In this paper the relations between the errors in measurements for the microwave surface resistance of a high-temperature superconducting thin film and the geometry and frequency of a parallel plate dielectric resonator were analyzed. The results showed that the influence of the 2a/L(ratio of the diameter of the dielectric rod to its length), the b/a (ratio of the radius of the metal cavity to the radius of the dielectric rod) and the frequency f on the error and the measurable minimum surface resistance Rsmin is quite important. The curves obtained in this paper could be used to design the dielectric resonators of parallel plate type. The error of order of 1% and Rsmin of the order of micro-ohm could be obtained by proper choosing 2a/L, b/a and f.
RESONANT RAMAN SCATTERING OF Hg1-xCdxTe 
Authors: HUANG SHI-HUA  , MO YU-DONG  ,   (1)昆明理工大学理学院,昆明650051; (2)昆明物理研究所,昆明650223
Published: December 2020

When the photon energy of an incident light is close to E0+Δ0 of Hg1-xCdxTe, we observe the resonant Raman scattering, “forbidden” resonant enhancement Raman scattering and the second-order resonant Raman scattering. We have analyzed the reason why we can observe the weak “forbidden” TO2 mode from the principal (100) face of Hg1-xCdxTe in the case of no resonant scattering; and also analyzed the reason why the “forbidden” TO2 mode from the principal (100) face of Hg1-xCdxTe increases significantly in the case of no resonant scattering. According to our analysis, we find that the second-order resonant Raman scattering by two LO phonons is caused largely by the interband Fr?hlich interaction.

Authors: LI CHUAN-AN  ,   菏泽教育学院物理系,菏泽274016
Published: December 2020

Using the first and third law of the black hole mechanics, we have derived the formula of the Planck absolute entrory of the black hole. The formula represents that the entrory of the black hole should be proprotional to the total area of the inner and outer horizons. And we have proven that the Planck absolute entrory of the black hole should be the classical thermodynamic entropy.

Widely employed in fundamental research, industrial processing, and biomedicine, femtosecond fiber lasers exhibit many attractive features such as high average power, good heat dissipation, excellent beam quality, and compact footprint. Coherent combining technology can effectively suppress the detrimental nonlinear and thermal effects in the fiber amplifiers, and therefore further increase the output pulse energy and average power of femtosecond fiber lasers. In this article, we mainly discuss different coherent combining techniques in high-power ultrafast Yb-fiber laser systems and the relevant phase-locking methods. We believe that the advent of new coherent combining techniques will further improve the average power and pulse energy of femtosecond fiber laser systems, thereby opening up some new research areas.

Telomere shortening is a presumed tumor suppressor pathway that imposes a proliferative barrier (the Hayflick limit) during tumorigenesis. This model predicts that excessively long somatic telomeres predispose to cancer. Here, we describe cancer-prone families with two unique TINF2 mutations that truncate TIN2, a shelterin subunit that controls telomere length. Patient lymphocyte telomeres were unusually long. We show that the truncated TIN2 proteins do not localize to telomeres, suggesting that the mutations create loss-of-function alleles. Heterozygous knock-in of the mutations or deletion of one copy of TINF2 resulted in excessive telomere elongation in clonal lines, indicating that TINF2 is haploinsufficient for telomere length control. In contrast, telomere protection and genome stability were maintained in all heterozygous clones. The data establish that the TINF2 truncations predispose to a tumor syndrome. We conclude that TINF2 acts as a haploinsufficient tumor suppressor that limits telomere length to ensure a timely Hayflick limit.
Absent phasing of respiratory and locomotor rhythms in running mice
Authors: Hérent Coralie , Diem Séverine , Fortin Gilles , Bouvier Julien
Published: December 2020

Examining whether and how the rhythms of limb and breathing movements interact is highly informative about the mechanistic origin of hyperpnoea during running exercise. However, studies have failed to reveal regularities. In particular, whether breathing frequency is inherently proportional to limb velocity and imposed by a synchronization of breaths to strides is still unclear. Here, we examined respiratory changes during running in the resourceful mouse model. We show that, for a wide range of trotting speeds on a treadmill, respiratory rate increases to a fixed and stable value irrespective of trotting velocities. Respiratory rate was yet further increased during escape-like running and most particularly at gallop. However, we found no temporal coordination of breaths to strides at any speed, intensity, or gait. Our work thus highlights that exercise hyperpnoea can operate, at least in mice and in the presently examined running regimes, without phasic constraints from limb movements.
Superlative syntactic amalgams in an Iberian Spanish dialect
Authors: Sáez del Álamo Luis Ángel
Published: December 2020

This article addresses an as yet unnoticed Spanish superlative construction attested in the mid area of Northern Spain. This construction features two striking properties: (i) it contains a relative pronoun which, at first glance, does not seem to introduce a TP (there is no overt verb to its right), which raises the question how the relative pronoun can obtain its Case/theta role; (ii) even if it were true that the relative pronoun actually introduces a TP and heads a full subordinate clause (presumably a free relative), the latter would arise in an anomalous position which disrupts the natural word order of the main clause and where it seems to lack any obvious licensor (as an adjunct, argument or predicate). A simultaneous answer to both problems will be obtained from the proposal that the construction at issue is a “syntactic amalgam” (Lakoff 1974): (i) assuming Kluck’s (2011) approach to amalgams, the relative pronoun of the construction can unproblematically be considered to introduce a sluiced TP, so it heads a full relative clause and does have a (covert) Case/theta-role licensor; (ii) the disruptive position of the relative clause and the opacity for licensing from the main clause are now expected as they are the defining properties of the so-called “interrupting clauses” in Horn-/Andrews-amalgams. As in Kluck (2011), such properties will be assumed to result from the operation “par-merge” giving rise to paratactical configurations (de Vries 2007).
How do we measure “measure”? Measure constructions and Metaphor
Authors: Kibisova Elizaveta
Published: December 2020

The article describes Russian measure constructions with the nominal quantifiers куча, груда, море, and туча. These nominal quantifiers are used in different, though overlapping, collocations determined by the semantics of the nouns. These nouns can be used in their literal meanings, or to create a metaphor. In rare cases, combination of metaphor and metonymy is used to add semantic nuances.
Effects of plastic mulching on the accumulation and distribution of macro and micro plastics in soils of two farming systems in Northwest China
Authors: Meng Fanrong , Fan Tinglu , Yang Xiaomei , Riksen Michel , Xu Minggang , Geissen Violette
Published: December 2020

Background

Inappropriate disposal of the plastic mulching debris could create macroplastics (MaPs) and microplastics (MiPs) pollution in agricultural soil.

Methods

To study the effects of farming systems on accumulation and distribution of agricultural plastic debris, research was carried out on two farming systems in Northwest China. Farming in Wutong Village (S1) is characterized by small plots and low-intensity machine tillage while farming in Shihezi (S2) is characterized by large plots and high-intensity machine tillage. In September 2017, we selected six fields in S1, three fields with 6–8 years of continuous plastic mulching (CM) as well as three fields with over 30 years of intermittent mulching (IM). In S2, we selected five cotton fields with 6, 7, 8, 15 and 18 years of continuous mulching. In both regions, MaPs and MiPs from soil surface to 30 cm depth (0–30 cm) were sampled.

Results

The results showed that in S1, MaPs mass in fields with 6–8 years CM (i.e., 97.4kg·ha−1) were significantly higher than in fields with 30 years IM (i.e., 53.7 kg·ha−1). MaPs in size category of 10–50 cm2 accounted for 46.9% in fields of CM and 44.5% in fields of IM of total collected MaPs number. In S2, MaPs mass ranged from 43.5 kg·ha−1 to 148 kg·ha−1. MaPs in size category of 2–10 cm2 account for 41.1% of total collected MaPs number while 0.25–2 cm2 accounted for 40.6%. MiPs in S1 were mainly detected in fields with over 30 years of intermittent mulching (up to 2,200 particles·kg−1 soil), whereas in S2 were detected in all fields (up to 900 particles·kg−1 soil). The results indicated farming systems could substantially affect the accumulation and distribution of agricultural plastic debris. Continuous plastic mulching could accumulate higher amount of MaPs than intermittent plastic mulching. High-intensity machine tillage could lead to higher fragmentation of MaPs and more severe MiPs pollution. These results suggest that agricultural plastic regulations are needed.
Assessing anxiety, depression and quality of life in patients with peripheral facial palsy: a systematic review
Authors: Cuenca-Martínez Ferran , Zapardiel-Sánchez Eva , Carrasco-González Enrique , La Touche Roy , Suso-Martí Luis
Published: December 2020

Objective

Peripheral facial palsy (PFP) is predominantly a unilateral disorder of the facial nerve, which can lead to psychological disorders that can result in decreased quality of life. The aim of this systematic review was to assess anxiety, depression and quality of life symptoms associated with PFP.

Data sources

We searched the Medline, PEDro, CINAHL and Google Scholar databases to conduct this systematic review while following Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. The search was performed by two independent reviewers, and differences between the two reviewers were resolved by consensus.

Study Selection

The search terms used were derived from the combination of the following MeSH terms: “facial paralysis”, “bell palsy”, “anxiety”, “anxiety disorders”, “depression”, “depressive disorders”, “quality of life” and not MeSH: “facial palsy”, “hemifacial paralysis”, “facial paresis”, “Peripheral Facial Paralysis”, using the combination of different Boolean operators (AND/OR).

Data Extraction

On November 1st (2019).

Data Synthesis

In total, 18 cross-sectional articles and two case-control studies were selected.

Conclusions

The cross-sectional articles showed low methodological quality, while the case-control studies showed acceptable methodological quality. Limited evidence suggests that patients with PFP might have increased levels of anxiety and depressive symptoms. A qualitative analysis also showed limited evidence that quality of life might be diminished in patients with PFP.

Moderating Effect of Vocational Calling on Firefighters’ Stress and Burnout
Authors: Choi HaeYoun
Published: December 2020

Firefighters are exposed to complex stresses resulting from life-threatening risks in the work environment, expanding scope of work, insufficient compensation and support. This study investigated the role of vocational calling in job stress leading to burnout, which impairs mental health and organizational effectiveness. One hundred and ninety-one firefighters (average age, 40.97 years; average career, 13.14 years) participated in the study. Firefighters with a high sense of calling showed lower burnout at both low and high stresses than those with a low sense of calling. In the group with low sense of calling, burnout increased more rapidly as the stress level increased than in the group with high sense of calling. As a psychological resource, sense of calling, which leads to the perception of one’s work as meaningful and purposeful, showed a moderating effect that buffers the effect of stress on burnout.

A Mini-review: Effect of Dunaliella salina on the Growth and Health of Fish
Authors: Pratiwi Dian Yuni
Published: December 2020

Fisheries is one of the sectors that can be developed to meet world food needs. The development of the fisheries is influenced by the availability of quality feeds. Dunaliella salina is a unicellular green algae that can be used as fish feeds. D. salina is known to contain many nutrients such as protein, carbohydrates, fats, pigments, and others. D. salina has also been shown to increase the growth rate of various types of fish. Not only for growth, but several studies have shown that D. salina has favorable effects on immunology. This article aims to explain the nutritional content and the effect of D. salina on the growth and health of fish. Based on the above studies, D. salina has the potential to be used as an alternative feed for various types of fish.
Manganese Inhibits Indomethacin-Induced Hepatorenal Oxidative Stress in Wistar Rats
Authors: Abiola Tijani Stephanie , David Olori Ogaraya , Olatunde Farombi Ebenezer
Published: December 2020

Aim: Manganese (Mn) is an essential trace element in many cellular processes. However, there is dearth of literature on its influence on indomethacin-induced hepatorenal damage. Therefore, this study was conducted to investigate the effect of manganese on indomethacin-induced hepatorenal damage in rats.

Methods: Rats were divided into four groups of eight rats consisting of control group, indomethacin (IND) alone (20 mg/kg), Mn alone (10 mg/kg) and co-treated group that were treated orally for 14 consecutive days. Twenty four hours after treatment, under pentobarbital anesthesia, blood was collected and liver was excised to prepare homogenate and histology staining. Liver and kidney function tests aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), malate dehydrogenase (MDH), glutamine dehydrogenase (GLDH), sorbitol dehydrogenase (SDH), glucose-6-phosphate dehydrogenase (G6PD), bilirubin (BIL), urea, creatinine, cholesterol (CHOL), triglycerides (TG), low and high density lipoprotein (LDL and HDL), electrolytes and oxidative stress superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and lipid peroxidation (LPO) biomarkers were assessed.

Results: The results showed that indomethacin caused hepatorenal damage in rats manifested with increase in serum hepatic and renal function biomarkers. But co-administration of IND with Mn significantly (p < 0.05) decreased the level of hepatorenal biomarkers. Additionally, co-administration of IND with Mn improved the antioxidant status with concomitant reduction of LPO and restored the integrity of the liver and kidney histologically.

Conclusion: The results of this study emphasize that co-administration of IND with Mn to rats alleviated IND-induced hepatorenal toxicities and oxidative stress in rats.

Objective

The objective of the study was the analysis of adherence and self‐perceived treatment response to long‐term botulinum neurotoxin type A (BoNT‐A) treatment in different neurological indications.

Methods

In this retrospective, monocentric, observational study, cross‐sectional and longitudinal data of 1351 patients documenting 20705 injection appointments at the BoNT outpatient clinic of Heinrich Heine University Duesseldorf between 1989 and 2014 were retrospectively analyzed. Patients had been treated with BoNT for neurological conditions, including cervical dystonia (CD), blepharospasm (BSP), other dystonia (ODT), hemifacial spasm (HFS), and spasticity (SPAS). The parameters longitudinally analyzed for the entire cohort were therapy duration as well as the mean and cumulative BoNT‐A dose. Cross‐sectionally, for subgroups of at least 721, patients’ global self‐perceived quality of health and life, global self‐perceived reduction of symptoms by BoNT‐A treatment as well as the clinical global impression were evaluated. Furthermore, mouse hemidiaphragm assay antibodies (MHDA‐ABs) were analyzed in a subgroup.

Results

The mean treatment duration was 4.58 years (95% CI 4.32–4.84), and 678 (50.2%) therapy dropouts of 1351 patients occurred within the first 8 years. Therapy adherence and self‐perceived symptom reduction in long‐term BoNT‐A treatment over the years were significantly longer in BSP, HFS, and CD patients than in ODT and SPAS patients.

Interpretation

The treatment indication determines long‐term adherence and self‐perceived symptom reduction in BoNT‐A therapy, which are better in BSP, HFS, and CD patients than in ODT and SPAS patients. MHDA‐ABs had a significant impact on global self‐perceived symptom reduction, but with only a limited degree.
Identifying the Bottleneck for Heat Transport in Metal–Organic Frameworks
Authors: Wieser Sandro , Kamencek Tomas , Dürholt Johannes P. , Schmid Rochus , Bedoya‐Martínez Natalia , Zojer Egbert
Published: December 2020

Controlling the transport of thermal energy is key to most applications of metal–organic frameworks (MOFs). Analyzing the evolution of the effective local temperature, the interfaces between the metal nodes and the organic linkers are identified as the primary bottlenecks for heat conduction. Consequently, changing the bonding strength at that node–linker interface and the mass of the metal atoms can be exploited to tune the thermal conductivity. This insight is generated employing molecular dynamics simulations in conjunction with advanced, ab initio parameterized force fields. The focus of the present study is on MOF‐5 as a prototypical example of an isoreticular MOF. However, the key findings prevail for different node structures and node–linker bonding chemistries. The presented results lay the foundation for developing detailed structure‐to‐property relationships for thermal transport in MOFs with the goal of devising strategies for the application‐specific optimization of heat conduction.
Synthesis of [1,2,3]‐Triazolo[5,1‐a]‐isoquinolines through TBAF‐Promoted Cascade Reactions
Authors: Duan Shengguo , Chen Yidian , Meng Hui , Shan Lihong , Xu Ze‐Feng , Li Chuan‐Ying
Published: December 2020

A tetrabutylammonium fluoride (TBAF)‐promoted detosylation cyclization cascade was developed for the synthesis of [1,2,3]‐triazolo[5,1‐a]‐isoquinolines. Most of the products were obtained in excellent yields under mild conditions. Valuable halogen‐substituted [1,2,3]‐triazolo[5,1‐a]‐isoquinolines could also be synthesized with a slight modification of the reaction conditions. Functionalized isoquinolines were obtained smoothly by denitrogenative reactions. The control experiments showed that this transformation was facilitated by TBAF and the water contained in the commercially obtained reagent. Deuterium labeling products could also be obtained easily in high yield.
Biodegradable membrane based on polycaprolactone/polybutylene succinate: Characterization and performance evaluation in wastewater treatment
Authors: Sadeghi Azadeh , Mousavi Seyed Mahmoud , Saljoughi Ehsan , Kiani Shirin
Published: December 2020

Biodegradable membranes with different compositions of polycaprolactone (PCL) and polybutylene succinate (PBS) are prepared via immersion precipitation. The morphology, hydrophilicity, chemical structure, crystalline structure, mechanical properties, and biodegradability of the membranes are studied to assess the effect of PBS concentration in the polymer blend on membrane properties. Furthermore, the performance of the obtained membranes is assessed through the treatment of wastewater sampled from the chips and snacks factory. Also, membranes' antifouling properties are assessed by filtration of a model foulant. The investigations revealed that the addition of PBS to PCL increases the membrane hydrophilicity and biodegradability. Regarding the results, the PCL membrane blended with 30 wt% PBS has 106%, 26%, and 37% higher pure water flux, flux recovery ratio, and permeate flux, in addition to the higher rejection of pollution indices, in comparison with the PCL membrane.

Published: December 2020

Lymphatic filariasis is a neglected parasitic disease that affects millions in tropical and subtropical countries and is caused by Wuchereria and Brugia species. Specific and sensitive detection methods are essential in mapping infected areas where rapid tests are needed to cover underdeveloped and remote regions, which facilitates eliminating the disease as a public health problem. A few commercialized rapid tests based on antigen or antibody detection are available, but the former only detects infection by Wuchereria species and cross‐reacts with nonlymphatic filaria, whereas antibody detection might provide positive results of previous infection. Here, we report the production of three different recombinant immunoglobulin gamma (IgG)1 antibodies based on scFvs previously generated via human antibody phage display technology, that is, anti‐BmR1 clone 4, anti‐BmXSP clone 5B, and anti‐BmXSP clone 2H2. The scFv sequences were cloned into a pCMV‐IgG1 vector, then transfected into a HEK293F cell line. The generated antibodies were found to be able to bind to their respective targets even at relatively low concentration. Conjugation of Fc to scFv induces binder stability and provides multiple labeling sites for probes and signaling molecules that can be used in rapid tests.

Authors: Nemati Afsaneh , Beyranvand Fatemeh , Assadollahi Vahideh , Salahshoor Mohammad Reza , Alasvand Masoud , Gholami Mohammad Reza
Published: December 2020

Objectives

Cerium is a member of the rare metals group and widely used in drug delivery, gene therapy, molecular imaging and medicine. In this study, we investigated the effect of different doses of Cerium (IV) oxide (CeO2) during pregnancy on neonatal mice ovaries, as well as its effect on blood biochemical parameters.

Methods

Thirty pregnant NMRI mice were divided into five groups: Control and 4 groups treated with CeO2 (10, 25, 80, 250 mg/kg.bw i.p) at the GD7 and GD14. The ovarian histological of neonatal (2 and 6 day‐olds), as well as blood serum of neonates at 15‐dpp were analyzed.

Results

Count of ovarian primordial follicles in neonates at 2 dpp showed a significant decrease in the groups treated with 80 and 250 mg/kg.bw doses of CeO2. There was also a significant decrease in ovarian primordial and primary follicles in neonates at 6‐dpp at 250 mg/kg.bw doses of CeO2 in the control (P < 0.05). There was no significant difference in serum levels of malondialdehyde and total antioxidant capacity between the experimental and control groups.

Conclusions

Our results suggest that the effects of CeO2 on the ovarian tissue of neonatal mice during pregnancy may be dose‐dependent.

Potential vector switching in the evolution of Bursaphelenchus xylophilus group nematodes (Nematoda: Aphelenchoididae)
Authors: Maehara Noritoshi , Kanzaki Natsumi , Aikawa Takuya , Nakamura Katsunori

To show the importance of vector switching of nematodes in the evolution of the Bursaphelenchus xylophilus group, we tested a hypothesis that “Bursaphelenchus doui (or its ancestor) was transferred by Acalolepta fraudatrix, Acalolepta sejuncta, and/or Monochamus subfasciatus (or their ancestral species) from broad‐leaved trees to conifers, switched vectors from these cerambycid beetles to Monochamus beetles in conifers, and then evolved into the common ancestor of Bursaphelenchus mucronatus and B. xylophilus.” We used a simple nematode‐loading method to beetles and produced 20 binary combinations of five B. xylophilus group species and four cerambycid beetle species in the tribe Lamiini. The affinity of the nematodes for the beetles was examined based on phoretic stage formation of the nematodes. Phoretic stages of B. doui appeared in all beetle species examined, namely Acalolepta luxuriosa, Psacothea hilaris, A. fraudatrix, and Monochamus alternatus, although the affinity of the nematode for M. alternatus was weak. This finding indicates that B. doui could switch vectors to conifer‐using Monochamus beetles after transfer by A. fraudatrix from broad‐leaved trees to conifers. We conclude that vector switching of nematodes could have potentially happened during the evolutionary history of the B. xylophilus group.
