AbstractThis follow-up study assessed the impact of a nitrate-rich diet on salivary nitrate/nitrite levels and the recovery of therapy-induced vascular impairments in a cohort of 39 periodontitis
patients treated by standard subgingival mechanical plaque removal (PMPR). At baseline, saliva samples for nitrate/nitrite analysis were collected, and peripheral/central blood and
augmentation pressure was documented using the Arteriograph recording system. Immediately after, PMPR vascular parameters were reassessed. All study patients received a randomly allocated
supply of a lettuce beverage to be consumed for 14 days, containing either a daily dosage of 200 mg nitrate (test group, n = 20) or being void of nitrate (placebo group, n = 19). At day 14,
salivary and vascular parameters were reassessed. Initial salivary and vascular parameters did not differ significantly between the groups. PMPR impaired all vascular parameters in both
groups with no differences between the groups. At day 14, salivary nitrate/nitrite levels of the test group were significantly elevated compared to baseline. All vascular parameters had
significantly recovered from the impairment inflicted by PMPR. In the placebo group, by contrast, salivary parameters did not differ significantly from baseline, and the recovery of impaired
vascular parameters was restricted to a significant improvement of diastolic blood pressure. Correlation analysis identified a significant inverse correlation between salivary
nitrate/nitrite sum and central/peripheral blood pressure and augmentation pressure. In conclusion, the data of this subanalysis suggest that increasing salivary nitrate/nitrite levels by a
diet rich in nitrate may improve recovery of therapy-induced vascular impairments after PMPR.
A two-color dual-comb system for time-resolved measurements of ultrafast magnetization dynamics using triggerless asynchronous optical sampling

Published: June 2023

We report on an Er-doped fiber (EDF)-laser-based dual-comb system that allows us to perform triggerless asynchronous optical sampling pump–probe measurements of ultrafast demagnetization and spin precession in magnetic materials. Because the oscillation frequencies of the two frequency-comb light sources are highly stabilized, the pulse-to-pulse timing jitter is sufficiently suppressed, and data accumulation without any trigger signals is possible. To effectively induce spin precession in ferromagnetic thin films, the spectral bandwidth of the output of one of the EDF frequency comb sources is broadened by a highly nonlinear fiber and then amplified at a wavelength of about 1030 nm by a Yb-doped fiber amplifier. The output of the other frequency comb source is converted to about 775 nm by second harmonic generation. We used this system to observe ultrafast demagnetization and spin precession dynamics on the picosecond and nanosecond time scales in a permalloy thin film. This time-domain spectroscopy system is promising for the rapid characterization of spin-wave generation and propagation dynamics in magnetic materials.

Clarifying the electronic and magnetic properties of lutetium, lutetium dihydride, and lutetium oxide is very helpful to understand the emergent phenomena in lutetium-based compounds (such as superconductivity-like transitions near room temperature). However, this kind of study is still scarce at present. Here, we report on the electronic and magnetic properties of lutetium metals, lutetium dihydride powders, and lutetium oxide powders. Crystal structures and chemical compositions of these samples were characterized by x-ray diffraction and x-ray photoemission spectroscopy, respectively. Electrical transport measurements show that the resistance of lutetium has a linear behavior depending on temperature, whereas the resistance of lutetium dihydride powders changes little with decreasing the temperature. More interestingly, paramagnetism-ferromagnetism-spin glass transitions were observed at near 240 and 200 K, respectively, in lutetium metals. To understand their origins, the measurement of inductively coupled plasma optical emission spectroscopy was performed, revealing that the concentrations of dilute magnetic impurities in lutetium and lutetium dihydride are around 0.01%, which can lead to the presence of spin glassy behavior. Our work uncovers the complex magnetic properties of lutetium and lutetium dihydride and suggests their close connections to the electronic and magnetic transitions of Lutetium-based compounds (such as Lu–H–N).
Existential predication and have-possessive constructions in the languages of the world
Authors: Creissels Denis 
Published: June 2023

Abstract
The present article deals with the relationship between have-possessive constructions and inverse-locational predication, a type of construction commonly characterized as ‘existential’, illustrated by English There is a cat in the tree (contrasting with the plain-locational clause The cat is in the tree). Some of the languages that have a transitive ‘have’ verb use the same verb as an inverse-locational predicator. Two types of historical explanations can be considered: either the inverse-locational construction developed from the impersonalization of a pre-existing have-possessive construction, or the possessive construction initially belonged to the locational-possessive type, but has undergone changes making the coding of the possessor more similar to that of A in transitive clauses and/or the coding of the possessee more similar to that of P (have-drift).
Impersonal existence in the weather domain
Authors: Meulleman Machteld , Paykin Katia 
Published: June 2023

Abstract
This contribution examines the co-existence in French of two impersonal constructions with a light verb and a weather noun, as in il y a / il fait du vent ‘it’s windy’ (lit. there is / it makes wind). Our starting point stems from Bauer’s (2000) observations on Vulgar Latin postulating that facere ‘do, make’ with weather nouns appears to compensate for the diminishing use of intransitive weather verbs. Based on a diachronic and synchronic corpus study of weather sentences extracted from Frantext, we argue that Bauer’s hypothesis can apply at best to Middle French. For Modern and Contemporary French, our analysis reveals that both constructions are existential with il fait+N specializing in expressing ambient states and the il y a-construction in expressing atmospheric events or substances.
On a continuum from categorical to thetic judgment
Authors: Gécseg Zsuzsanna , Sarda Laure 
Published: June 2023

Abstract
This paper addresses the relationships between the existential reading of sentences with an indefinite subject and the presence of a spatial anchoring constituent. We investigated a corpus of French sentences with indefinite subjects in preverbal position and their translation into Hungarian. While French has a rather rigid word order, Hungarian is a discourse configurational language which signals the informational status of sentence constituents. Through the prism of differentiations made in the Hungarian translation, we distinguished two groups of indefinite subject sentences, one having a thetic interpretation, the other retaining a categorical – or categorical-like – interpretation despite the indefinite form of the subject. These sentences illustrate the fact that while indefinite NPs are known to be bad topics, they can nevertheless play this role to various degrees.

Authors: Chen Feng , Wang Ning , Ma Tao 
Published: June 2023

Abstract
A meso-scale mechanical analysis approach, which is essentially based on the use of smart aggregate sensor, was employed to inquire the dynamic responses of smart aggregate in cold recycled asphalt mixtures during gyratory compaction, including as well an investigation over the critical influence factors. The discrete element method (DEM) was further applied to study the interaction behaviors of smart aggregate with the surrounding particles. The laboratory test results showed that smart aggregate is an effective method to monitor the contact force and rotation variation between the aggregates, and the changes in the mechanical and physical properties of the mixtures can be characterized by the monitoring results of smart aggregate. In addition, the results of DEM analyses show that the mixtures with 55% coarse aggregates have higher normal force and lower kinetic energy during gyratory compaction, revealing the influence mechanism of the effect of coarse aggregate content on smart aggregate monitoring results at the meso-scale.

Published: June 2023

Abstract
To improve the behavior of hollow concrete filled steel tube, a novel type of reinforced hollow concrete circular steel tubular member (RHCFST) was put forward and its axial behavior was studied. The finite element analysis model of 12 RHCFST short columns under axial compression was established by using ABAQUS. The influence of steel tube’s strength and wall thickness, diameter of steel bar with normal strength, sandwich concrete’s thickness and strength on the mechanical properties of members were investigated. The results showed that the loading process can be defined as five stages: elastic, elastoplastic, descending, strengthen and gentle stage. The new composite structure has good cooperative performance. The ultimate bearing capacity increaseswith the increase of yield strength and wall thickness of steel tube, thickness and strength of sandwich concrete and diameter of steel bar with normal strength.

Abstract
Under the environment of large temperature differences, the Sichuan-Chongqing UHV project is located at the high-altitude area, and the universal bellows compensator which cannot meet the requirements of large displacement is prone to instability. This paper proposes the design scheme of modified pantograph linkages bellows compensator by studying the instability mechanism of the bellows and improving the structure of the compensator. The overall size is reduced, the stress and the deformation of the flange are decreased, and the stability of the compensators are enhanced. According to mechanics theories, the corresponding relationship among displacement, spring rate and the spring rate force was discovered. The equations of lateral displacement of bellows with high accuracy was established. And the final experimental displacements were obtained after two steps of calculating.
Case Calculation and Analysis of Insufficient Traction Force in Elevator
Authors: Ren Zhaolin 
Published: June 2023

Abstract
For the traction driven elevator, the satisfaction of traction conditions is the basic guarantee for the normal operation of the elevator. If the traction force is insufficient, there will be skid, slip and other phenomena, which not only cannot meet the design requirements of the elevator manufacturers, but also easy to cause safety accidents. The equivalent friction coefficient f (depending on groove shape, groove material and groove lubrication) and the wrap angle of the wire rope on the traction wheel play a decisive role in the traction force. Based on a case of insufficient traction force caused by too small Angle, the cause of its failure is calculated and analyzed, and corresponding corrective measures are put forward to avoid the occurrence of such problems.
Dynamic Response of Landscape Tower with Curved and Twisted Columns and Spiral Beams Based on Wind Tunnel Test
Authors: Liu Yongjie , Zhao Shuang , Yue Jiahao 
Published: June 2023

Abstract
The displacement and comfort of the tower top are important reference indexes for wind resistance design of the curved torsional column spiral beam landscape tower (LT). The dynamic response of tower top and platform is analyzed and discussed through wind tunnel test of aeroelastic model, and the influence of the tower itself on wind response and comfort of pedestrian is studied. The conclusion shows that the wind Angle has a great influence on the displacement of the top of the landscape tower, and the 150° wind Angle is the most unfavorable wind Angle of LT displacement. In addition, the peak acceleration of the platform reaches its maximum value at 90° wind Angle, resulting in poor lateral pedestrian comfort at high wind speed. It is suggested to restrict pedestrians from climbing the tower at high wind speed or to carry out vibration reduction research on such structures at high wind speed.

Published: June 2023

Abstract
By conducting collapsibility test, the changing rule of collapsibility coefficient of remolded loess is obtained. According to the numerical simulation method of equivalent humidity field with temperature field, the collapsibility coefficient is converted into temperature change, so the calculation of wetting settlement is realized. The results show that the collapsibility coefficient of loess decreases significantly with the increase of compaction degree and initial water content. It increases first and then decreases with the increase of overlying pressure at lower compaction degree, while increases gradually with the increase of overlying pressure at higher compaction degree. The numerical simulation based on the theory of equivalent humidity field with temperature field can accurately simulate the wetting settlement test results of remolded loess.

Abstract
Microwave dielectric ceramics with low dielectric constants are widely used in the design and fabrication of microwave devices. Here, low-temperature sintered Li2Mg1.91Na0.18Mo3-x
W
x
O12 (LMNMWO) (x takes values from 0 to 0.15) ceramics are prepared by the solid-phase reaction technology. XRD and BSE patterns indicated that W6+ is solidly dissolved into the lattice and exhibits an overall single phase. The dielectric properties of the ceramics are effectively enhanced by the substitution of Mo6+ for W6+. The trends of density and SEM microscopic morphology show that the trace W6+ substitution can effectively promote grain growth and enhance grain homogeneity. The results indicate that the Q×f values are related to the relative density and grain homogeneity. The EDS spectrum demonstrates that the ratio of elements is close to the chemical formula of Li2Mg1.91Na0.18Mo2.95W0.05O12. The trend of τf values is related to the lattice distortion generated when W6+ is irregularly solidified into the lattice. Specifically, dielectric properties of the substituted LMNMWO (x = 0.05) ceramics are determined as follows: εr
= 8.3, Q×f = 48357 GHz, and τf = -59 ppm/°C.

Published: June 2023

Abstract
In order to study the impact resistance performance of ultra-high performance concrete (UHPC) slab with basalt fiber, the experiment of six concrete slabs was conducted. The following factors were considered in this study: different basalt fiber types, steel mesh, and water-based epoxy mixture. The drop weight method was used, and the effect of various factors on the impact resistance performance of ultra-high performance concrete slab with basalt fiber were investigated in details. The test results showed that the basalt fiber could significantly increase the impact resistance of UHPC slab. The basalt fiber with a long length after cracking was more significant to improve the impact resistance performance of UHPC slab. The basalt fiber, steel mesh, and water-based epoxy can significantly improve the impact resistance and energy absorption capacity of UHPC slab. The ductility coefficient of UHPC slabs are less than 0.6.

Published: June 2023

Abstract
This article investigated the sensitivity of each acoustic feature to steel plate defects through the coin-tapping method in order to improve acoustic detection methods precision and intelligent detection efficiency. 87 acoustic characteristic parameters of detection signals were researched including time domain, frequency domain, and time-frequency domain. 10 kinds of percussion conditions were designed to meet the two classifications of acoustic signals. The degree of contribution of acoustic parameters to damage detection was arranged by sensibility analysis, which could be used as a basis for selecting acoustic parameters for similar structural damage detection. The characteristic vectors of various parameter combinations were determined as the inputs of the acoustic detection method by analysing the sensitivity and correlation of different parameters. The multi-parameter feature vector with low redundancy was obtained by correlation analysis, which could be used as a combination method of the input value of the damage recognition classifier. The results show that the zero-crossing rate, main frequency and time-frequency domain parameters have high damage sensitivity, and there are always low-correlation feature pairs between them. The research results provide solutions for the selection and combination of feature parameters for similar data classification problems.

Abstract
In order to study the evolution law of tunnel convergence deformation during the construction of shallow buried unsymmetrical pressure tunnel, the deformation characteristics and evolution law of shallow buried unsymmetrical pressure tunnel during the three-step construction method are studied based on the background of Qingshui No. 2 tunnel project and numerical simulation. The results show that: with the tunneling, when the tunneling depth is less than 40m, the settlement deformation gradually decreases, and the maximum settlement is at the entrance; When the tunnel footage is greater than 40m, the settlement deformation first increases and then decreases. The maximum settlement of the arch crown is 15m in front of the tunnel face, while the maximum settlement of the arch shoulder is 20m in front of the tunnel face; The maximum value of arch waist convergence appears at 10m in front of the tunnel; The effective combination of numerical simulation and monitoring technology can provide guidance for engineering practice.

Abstract
Stomatal is the most crucial part of plant organs that function as the gas exchange between CO2 and O2 in the environment through diffusion. Optimal stomatal performance can improve the quality of plant growth. This research aimed to determine the relationship between stomatal parameters and the production of red chili (Capsicum annuum L) under shade treatment conditions. This research was conducted in the field with three kinds of treatments, namely (1) control (without shade), (2) 50% shade, and (3) 80% shade. The parameters observed in this study were the number of stomatal, pore stomatal, stomatal area. The data were then analyzed using the correlation coefficient (r) calculation approach. The results showed that the closest relationship was found in the stomatal area variable with a pore area of 0.98. The stomatal characteristic that has the closest relationship with the production of red chili (Capsicum annuum L) is the pore area with a value of r = 0.73. These results indicate that pore area can be used as an indicator of crop production level.
