Stochastic acceleration in extreme TeV BL Lacs through MCMC
Authors: Sciaccaluga A. , Tavecchio F. , Landoni M. , Costa A. 
Published: May 2024

Context. Extreme TeV BL Lacs are a class of blazars with unique spectral and temporal features that are not easily reproducible using standard one-zone models based on single shock acceleration. To account for their peculiar properties, we elaborated a two-step acceleration model in which a recollimation shock and the subsequent downstream turbulence energize non-thermal electrons.
Aims. We applied the model to a sample of extreme TeV BL Lacs with well-characterized spectral energy distributions. Since we used several sources, we automatized the exploration of the parameter space. This allowed us to derive the parameter distributions and study the correlations among them.
Methods. We numerically solved a system of two coupled nonlinear differential equations to obtain the non-thermal particles and turbulence spectra. We calculated the spectral energy distribution via the synchrotron self-Compton emission model. The automatization of the parameter space exploration is possible through a Markov chain Monte Carlo (MCMC) ensemble sampler, in our case emcee.
Results. We derived well-defined posterior distributions for the parameters, showing that the model is well constrained by available data and demonstrating the suitability of our method. The cross-correlations among some of the physical parameters are not trivial. Therefore, we conclude that MCMC sampling is a key instrument for characterizing the complexity of our multiparameter phenomenological model.

Aims. The KEYSTONE project aims to enhance our understanding of solar-like oscillators by delivering a catalogue of global asteroseismic parameters (Δv and vmax) for 173 stars, comprising mainly dwarfs and subgiants, observed by the K2 mission in its short-cadence mode during campaigns 6–19.
Methods. We derive atmospheric parameters and luminosities using spectroscopic data from TRES, astrometric data from Gaia, and the infrared flux method (IRFM) for a comprehensive stellar characterisation. Asteroseismic parameters are robustly extracted using three independent methods, complemented by an iterative refinement of the spectroscopic analyses using seismic log g values to enhance parameter accuracy.
Results. Our analysis identifies new detections of solar-like oscillations in 159 stars, providing an important complement to already published results from previous campaigns. The catalogue provides homogeneously derived atmospheric parameters and luminosities for the majority of the sample. Comparison between spectroscopic Teff and those obtained from the IRFM demonstrates excellent agreement. The iterative approach to spectroscopic analysis significantly enhances the accuracy of the stellar properties derived.
Chemical evolution of the Galactic bulge with different stellar populations
Authors: Molero M. , Matteucci F. , Spitoni E. , Rojas-Arriagada A. , Rich R. M. 
Published: May 2024

Context. The metallicity distribution function (MDF) of the Galactic bulge is characterized by a multi-peak shape, with a metal-poor peak centered at [Fe/H] ∼ −0.3 dex and a metal-rich peak centered at [Fe/H] ∼ +0.3 dex. The bimodality of the MDF is also reflected in the [α/Fe] versus [Fe/H] abundance ratios, suggesting the presence of different stellar populations in the bulge.
Aims. In this work we aim to reproduce the observed MDF of the Galactic bulge by testing a scenario in which the metal-poor component of the bulge is formed by stars formed in situ, during a strong burst of star formation, while the metal-rich population is formed by stars created in situ during a second burst of star formation and/or stars accreted from the innermost part of the Galactic disk as an effect of a growing bar.
Methods. We adopted a chemical evolution model that is able to follow the evolution of several chemical species with detailed nucleosynthesis prescriptions. In particular, because of the importance of the production of Fe in constraining the MDF, close attention is paid to the production of this element in both Type Ia supernovae and massive stars. In particular, we included yields from rotating massive stars with different rotational velocity prescriptions. Our model also takes the infall and outflow of gas into account, as well as the effect of stellar migration. Results are compared to ∼13 000 stars from the SDSS/APOGEE survey that belong to the region located at a Galactocentric distance RGC ≤ 3.5 kpc.
Results. We successfully reproduce the observed double-peak shape of the bulge MDF as well as the abundance trends of the α elements relative to Fe by assuming both (i) a multi-burst star formation history with a quenching of the first burst of ∼102 Myr and (ii) migration of stars from the innermost part of the Milky Way disk, as an effect of a growing bar. According to our results, the fraction of the stellar mass of the bulge-bar that belongs to the inner disk is ∼40%. In terms of the nucleosynthesis, we conclude that models that assume either no rotation for massive stars or a distribution of rotational velocities that favors slow rotation at high metallicities best reproduce the observed MDF as well as the [α/Fe] and the [Ce/Fe] versus [Fe/H] abundance patterns.

Low Concentration of Lipoprotein(a) is an Independent Predictor of
Incident Type 2 Diabetes
Authors: Liu Wenhao , Zhang Guanzhao , Nie Zifan , Guan Xiangfeng , Sun Tingting , Jin Xiaodong , Li Bo 
Published: May 2024

AbstractThe aim of the study was to assess the association between lipoprotein(a) [Lp(a)]
concentration and incident type 2 diabetes. A meta-analysis of qualified studies
on the relationship of low levels of Lp(a) concentration with incident type 2
diabetes was conducted. PubMed and Cochrane libraries were searched for
randomized controlled trials containing data on events. Seven randomized trials
with 227178 subjects were included in this analysis. We found an inverse
association of the levels of Lp(a) concentration with risk of type 2 diabetes
with approximately 37% lower relative risk in the group with the highest
concentration compared with group with the lowest concentration. The current
available evidence from prospective studies suggests that there is an inverse
association between the levels of Lp(a) concentration and risk of type 2
diabetes, with a higher risk of type 2 diabetes at low levels of Lp(a)
concentration. Therefore, we believe that the low levels of Lp(a) concentration
is an independent predictor of incident type 2 diabetes.
The Nasal Locator: An Innovative Instrument to Define the Exact Point of Osteotomy in Preservation or Structural Rhinoplasty
Authors: Mireas George 
Published: May 2024

AbstractOne of the most common components of most dorsal preservation (DP) techniques is subdorsal septal excision. Whatever the instrument used for this procedure (piezoelectric, Rongeur, or long scissors), it is paramount to be able to determine the exact subdorsal point (SDoP) at which the osteotomy/ostectomy (or cartilage cut) has been reached. First, to avoid any unnecessary extension of the osteotomy that increases the risk of fracture spreading into the cribriform plate and a consequent cerebrospinal fluid leak; second, to be sure that the subdorsal cut is high enough and can be combined/unified with the planned radix osteotomy.In addition, transverse osteotomies are usually necessary in both preservation and structural rhinoplasties. Even though many surgeons are satisfied with their osteotomy lines, it sometimes proves difficult to be sure of their position, especially during a DP rhinoplasty when both the transverse lines have to go in the direction of the planned radix osteotomy.We have developed the Nasal Locator (NL) to precisely define various nasal points of interest, such as a subdorsal cut (cartilaginous or bony), or a transverse or medial osteotomy line. It ends in two tips. The lower tip is placed at the point we wish to determine (e.g., SDoP or a transverse osteotomy), while the upper tip is fixed a certain distance from it (in all three dimensions), showing its exact location.Our in-depth research of the literature and the market has not revealed any device similar in form and function to the NL.We have been using the NL for almost 2 years and are confident of its usefulness. It is easy to use, and practically no time is needed to become familiar with it. During surgery, it is needed for less than 30 seconds and is risk-free. It is fully sterilizable and can be used repeatedly.
Excessive Blood Pressure Rise and Cardiovascular Remodeling in
Marathon Runners
Authors: Gwag Hye Bin , Kim Young-Joo , Park Kyoung-Min 
Published: May 2024

AbstractExercise-induced hypertension (EIH) is thought to be associated with increased
cardiovascular (CV) risks. However, no previous studies have investigated the
effects of EIH on CV systems in marathon runners without CV risk factors using
both 24-hr ambulatory blood pressure (BP) monitoring and exercise stress
echocardiography (ESE). This study firstly described differences in CV
adaptations according to EIH assessed by both exams. Marathon runners between 35
and 64 years of age without CV risk factors were eligible. All the participants
underwent both 24-hr ambulatory BP monitoring and ESE. EIH was defined as a
maximal exercise systolic BP≥210 mmHg. The EIH group (n=19) had shorter training
history and higher exercise intensity compared to the non-EIH group (n=23). The
average systolic BP was higher in the EIH group than in the non-EIH group. Left
cardiac chamber size and left ventricular mass (LVM) were also higher in the EIH
group compared to the non-EIH group. Maximal BP during ESE was positively
correlated with both parameters. Exaggerated BP response during exercise needs
to be monitored for pre-emptive measurements before it results in progressive
cardiovascular maladaptation.
Exploring textual–visual strategies in internet-based light food advertising: a study of Taobao advertisements in China
Authors: Yong Qian , Rao Xiaoqin 
Published: May 2024

AbstractAmidst global health concerns such as COVID-19 and rising obesity rates, the connection between food choices, societal well-being, and cultural shifts has gained attention. In China, the rise of “light food” consumption on platforms like Taobao reflects a growing trend towards health-conscious dietary preferences. With a dataset comprising 633 images and 45,817 words, condensed into 50 images for analysis, this research aims to understand how these advertisements influence perceptions of healthiness and desirability, and whether there is a discrepancy between advertised health benefits and actual nutritional content. This study delves into the advertising strategies employed for light food products on the Taobao platform in China, utilizing a Textual–Visual Thematic Analysis (TVTA) framework. Noteworthy findings include: (1) Internet-based light food advertising adopts a dual textual and visual approach. (2) Identification of prevalent multimodal devices, such as medium shots, varied camera angles, vibrant colors, and large size. (3) Uncovering inconsistencies in presentation that may pose potential consumer misperceptions. These discoveries underscore the nuanced landscape of light food advertising, offering valuable insights for both academia and industry.
Potential of increasing yield of spring Brassica napus canola by using Brassica rapa gene pool with emphasis on yellow sarson
Authors: Kebede Berisso , Habibi Gholamreza , Rahman Habibur 
Published: May 2024

Context Broadening the genetic base of canola (Brassica napus) is needed to develop improved hybrid cultivars. Wide genetic diversity is present in its parental species B. rapa and B. oleracea. In the case of B. rapa, the yellow sarson type from Asia is genetically distinct from all other types. Aims The objective of this research was to investigate the prospect of using yellow sarson to improve the performance of hybrid canola cultivars. Methods Inbred B. napus canola lines derived from an B. napus × B. rapa interspecific cross, and their F1 hybrids with the B. napus parent, as a tester, were compared on agronomic and seed quality traits; the inbreds were also evaluated for genetic diversity by using molecular markers. Key results Seed yield of the hybrids was significantly greater than the inbreds and the B. napus parent and exhibited more than 15% mid-parent heterosis (MPH). Genetic diversity did not show significant correlation with seed yield in the inbred population; however, it showed a positive correlation with MPH. Inbred yield as well as MPH showed a positive correlation with hybrid yield. For other traits, the performance of the inbreds showed a significant positive correlation with the performance of the hybrids; the average MPH for these traits was low or close to zero. Conclusions The yellow sarson gene pool showed great potential for use in the breeding of hybrid canola. Implications The knowledge gained and germplasm developed from this research can be used by breeders and researchers to develop improved canola cultivars.
Mandarin posture verbs
Authors: Newman John , Zhang Ying 
Published: May 2024

Abstract
Posture verbs have attracted considerable interest within Cognitive Linguistics. This study continues this line of
research by investigating usage-based patterns associated with these verbs when used in their literal posture senses. The data for
the study comes from the Lancaster Corpus of Mandarin Chinese and the CALLHOME Mandarin Corpus. We investigate the frequencies and
distributions of the Mandarin posture verbs 坐 zuò ‘sit’, 站 zhàn ‘stand’, and 躺 tǎng ‘lie’ in four construction types: directional constructions, aspectual
suffixes, serial verb constructions, and locative constructions. The analysis confirms the primacy of zuò, zhàn,
and tǎng and, among other results, reveals a significant absence of locative phrases with the dynamic forms of
the verbs as used with directionals.
Dialectal distinctions in Plngawan Atayal
Authors: Goderich Andre 
Published: May 2024

Abstract
Plngawan Atayal can be subdivided into two varieties: Sami’uɹ and Macagis. This subdialectal distinction went
mostly unnoticed in linguistic publications barring a short mention by Chen (2012).
Despite living in the same village since 1938, elderly speakers of both varieties have retained a number of unique phonological
features. These features not only allow us to distinguish contemporary varieties, but also let us identify data from older
publications. An examination of works by Ferrell (1969) and Li (1981, 1985) has revealed a prevalence of Sami’uɹ data, with a
small number of Macagis lexemes.
The moral grammar of marriage rules
Authors: Jones Doug 
Published: May 2024

Abstract
According to theories of “moral grammar,” judgments of what is wrong or right – like judgments of what is
ungrammatical or grammatical – are guided by implicit, often unconscious rules. An ideal test case for exploring the parallels
between moral rules and language rules is the moral regulation of mating in relation to kinship. Here I argue that combinatorial
variation in both kin terminologies and marriage rules results from the operation of a grammar faculty, which juggles tradeoffs
between conflicting constraints according to the principles of “Optimality Theory.” This works to produce kinship grammars,
input-output systems that map some kin types onto others via mergers and reductions. This in turn can yield marriage rules. If a
kin type maps onto a close consanguine, this corresponds to a marriage proscription. If a kin type maps onto a close affine, this
corresponds to a marriage prescription/preference. I analyze both elementary structures of kinship (where cross kin are prescribed
spouses, and parallel kin are proscribed; e.g. Dravidian southern India) and complex structures (where kin are divided into an
unmarriageable core and a marriageable periphery, and affines are sometimes tabooed because they are equated with close
consanguines; e.g. Jane Austen’s England). Rather than treating social organization as the source of mental categories, this
analysis starts with the machinery of categorization and shows how it spontaneously generates marriage rules. The result is an
updating of structuralism in light of cognitive science: moral codes vary within limits set by fundamental structures of the human
mind.
Controlling stick–slip in low-speed motion with a lifting force of magnetic fluid
Authors: Hu Lulu , Ma Chenbo , Dai Qinqwen , Huang Wei , Wang Xiaolei 
Published: May 2024

Abstract
Stick–slip is a standard friction-induced self-excited vibration that usually occurs in the boundary or mixed lubrication regimes. Broadening of the hydrodynamic lubrication regime is conducive to suppressing stick–slip motion. In this paper, the load carrying capacity of a magnetic fluid (MF) film in the presence of a magnetic field is derived based on the modified Reynolds equation. An additional lifting force produced by MF under the magnet was applied between the tribopairs to achieve the full fluid lubrication. Thus, the stick–slip is expected to be inhibited in a lower speed scope. The effect of magnet thickness on the lifting force is investigated experimentally and theoretically. Special attention is given to the influence of the lifting force on the friction and the critical transition speed of the hydrodynamic lubrication regime. Results demonstrate that the lifting force increases with the increment of the magnet thickness. The presence of the additional lifting force expands the hydrodynamic lubrication and makes the critical transition speed move left, as shown by the friction transitions on the Stribeck curve. Therefore, stick–slip motion can be suppressed at a lower sliding speed. Such beneficial effects are more pronounced in thicker magnets. It can be confirmed that, so long as the lifting force is higher than the normal load, the friction will invariably operate in the full film lubrication and the stick-slip motion may be eliminated theoretically.
Ultra-narrow dual-band perfect absorber based on double-slotted silicon nanodisk arrays
Authors: Yang Can , Luo Minghe , Ju Xiongwu , Hu Jinyong 
Published: May 2024

Abstract
Due to its unique advantage of optical properties, nanophotonic metamaterials have gained extensive applications in perfect absorbers. However, achieving both dual-band and ultra-narrow linewidth in absorbers simultaneously remains a challenge for typical metal-dielectric based metamaterials. In this work, a dual-band ultra-narrow perfect absorber consisting of a double slotted silicon nanodisk array that located on a silver film with a silica spacer layer is proposed theoretically. By combining the hybrid mode excited by the coupling of diffraction wave mode and magnetic dipole mode with the anapole–anapole interaction, two absorption peaks can be induced in the near-infrared regime, achieving nearly perfect absorbance of 99.31% and 99.61%, with ultra-narrow linewidths of 1.92 nm and 1.25 nm respectively. In addition, the dual-band absorption characteristics can be regulated by changing the structural parameters of the as-proposed metamaterials. The as-designed metamaterials can be employed as efficient two-channel refractive index sensors, with sensitivity and figure of merit (FOM) of 288 nm RIU−1 and 150 RIU−1 for the first band, and sensitivity and FOM of up to 204 nm RIU−1 and 163.2 RIU−1 for the second band. This work not only opens up a new design idea for the realization of dual-band perfect absorber synchronously with ultra-narrow linewidth, but also provides potential attractive candidates for developing dual-frequency channel sensors.
Self-consistent calculation of the optical emission spectrum of an argon capacitively coupled plasma based on the coupling of particle simulation with a collisional-radiative model

Published: May 2024

Abstract
We report the development of a computational framework for the calculation of the optical emission spectrum of a low-pressure argon capacitively coupled plasma (CCP), which is based on the coupling of a particle-in-cell/Monte Carlo collision simulation code with a diffusion-reaction-radiation code for Ar I excited levels. In this framework, the particle simulation provides the rates of the direct and stepwise electron-impact excitation and electron-impact de-excitation for 30 excited levels, as well as the rates of electron-impact direct and stepwise ionization. These rates are used in the solutions of the diffusion equations of the excited species in the second code, along with the radiative rates for a high number of Ar-I transitions. The calculations also consider pooling ionization, quenching reactions, and radial diffusion losses. The electron energy distribution function and the population densities of the 30 excited atomic levels are computed self-consistently. The calculations then provide the emission intensities that reproduce reasonably well the experimentally measured optical emission spectrum of a symmetric CCP source operated at 13.56 MHz with 300 V peak-to-peak voltage, in the 2–100 Pa pressure range. The accuracy of the approach appears to be limited by the one-dimensional nature of the model, the treatment of the radiation trapping through the use of escape factors, and the effects of radiative cascades from higher excited levels not taken into account in the model.
Drilling errors compensation of industrial robot based on 3D passive scale tracker

Published: May 2024

Abstract
In order to increase the machining accuracy of industrial robots, a drilling system based on a 3D passive scale tracker (3DPST) and Epson industrial robot was established. The real-time positioning errors of the robot were measured by 3DPST, and the orientation errors were analyzed according to position coordinates on a circular path. Therefore, the 6-DOF pose errors of the robot were measured. Building upon this foundation, a cyclic compensation method for robot pose errors was proposed. This method prioritizes the compensation of orientation errors followed by the compensation of positioning errors. Robot circular path tests and drilling experiments of aluminum alloy and plexiglass materials are carried out to verify the effectiveness of the error measurement compensation method. The results of coordinate measuring machine measurements indicate that, after robot error compensation, the machining accuracy of the machined holes in both materials is significantly improved. The positioning errors of the machined holes for aluminum alloy decreases from the range of 1.188–1.576 mm to 0.154–0.215 mm, while for plexiglass, it decreases from 1.226–1.437 mm to 0.132–0.183 mm.
