Abstract
Objective Pelvic movements when walking should be objectively evaluated in
the context of clinical data in order to understand the function of compensatory
mechanisms in the onset and management of symptomatic degenerative lumbar
stenosis (DLS). The purpose of this study was to compare patients treated with
decompression surgery (DS) and patients with symptomatic DLS in terms of pelvic
movements while walking.
Materials and Methods A total of 107 participants were included in this
study. 34 patients who underwent DS performed by the same surgeon were selected
as the DS group, while 39 patients with DLS who required surgery were selected
as the DLS group. The control group consisted of 34 age-matched healthy
individuals who had no disease and no gait disorder. The BTS G-WALK sensor
system (G-Walk) was used to measure pelvic movements (tilt, rotation, obliquity)
and gait parameters (speed, cadence, stride length).
Results DS and control groups had decreased maximum (p=0.008 and
p=0.006, respectively) and minimum anterior tilt of the pelvis
(p=0.015 and p=0.001, respectively) compared to the DLS group.
There was no significant difference between the groups for rotation, oblique and
tilt range of motion of the pelvis (p>0.05). Compared to the control
group, speed during gait were significantly lower in both the DLS
(p=0.012) and DS groups (p=0.016).
Conclusions In this study, decompression surgery was found to affect
pelvic movements. Patients with DLS walked differently from those who had no
symptoms, and this difference usually disappeared following surgical
decompression. Pelvic movements may serve as a helpful screening measure to
identify early compensatory mechanisms. Key words: lumbar stenosis, pelvic

AbstractA new approach was developed for the thiolation of halogenated pyrazole-5-amines under blue LED irradiation in metal-free conditions. This efficient and practical approach enabled the generation of thiolated pyrazol-5-amine building blocks of medicinal significance. This straightforward technique permits photochemical thiolation by an electron donor–acceptor by two distinct processes; formation of a charge-transfer complex through a halogen bond or π–π interaction based on various halogenated pyrazolamines, depending on the HOMO–LUMO energy gap of the C–X bond. The reaction of halogenated pyrazol-5-amines with thiophenol derivatives proceeded in good to excellent yields. The formation of a π–π complex or halogen bonding between the halopyrazolamine and the thiolate anion was confirmed by UV/visible spectroscopy.

Published: July 2023

AbstractAn atom-economical strategy for the synthesis of alkylated β3-acylamino amides via Lewis acid catalyzed one-pot multicomponent reaction of ynamides, carboxylic acids, and aromatic amines with aliphatic aldehydes is described. In addition to the synthetic utility and scalability, the method exhibits excellent substrate scope and functional-group tolerance. The products can easily be transformed into valuable building blocks, such as peptide chains.
The Right Ventricle in Pulmonary Hypertension

Published: July 2023

AbstractThe right ventricle plays a pivotal role in patients with pulmonary hypertension (PH). Its adaptation to pressure overload determines a patient's functional status as well as survival. In a healthy situation, the right ventricle is part of a low pressure, high compliance system. It is built to accommodate changes in preload, but not very well suited for dealing with pressure overload. In PH, right ventricular (RV) contractility must increase to maintain cardiac output. In other words, the balance between the degree of RV contractility and afterload determines stroke volume. Hypertrophy is one of the major hallmarks of RV adaptation, but it may cause stiffening of the ventricle in addition to intrinsic changes to the RV myocardium. Ventricular filling becomes more difficult for which the right atrium tries to compensate through increased stroke work. Interaction of RV diastolic stiffness and right atrial (RA) function determines RV filling, but also causes vena cava backflow. Assessment of RV and RA function is critical in the evaluation of patient status. In recent guidelines, this is acknowledged by incorporating additional RV parameters in the risk stratification in PH. Several conventional parameters of RV and RA function have been part of risk stratification for many years. Understanding the pathophysiology of RV failure and the interactions with the pulmonary circulation and right atrium requires consideration of the unique RV anatomy. This review will therefore describe normal RV structure and function and changes that occur during adaptation to increased afterload. Consequences of a failing right ventricle and its implications for RA function will be discussed. Subsequently, we will describe RV and RA assessment in clinical practice.

Abstract
Objective The aim of this study was to examine a method for measuring femoral trochlear morphology in dogs using ultrasonography, and survey femoral trochlear morphology in skeletally normal dogs.
Study Design To examine the validity of ultrasonography, three raters measured the sulcus angle (SA; the angle between the medial and lateral facets) five times in five skeletally normal dogs. Intra- and interrater reliabilities were then calculated. We also calculated the correlation coefficient between SAs measured using ultrasonography and computed tomography (CT) or magnetic resonance imaging (MRI). Then, we surveyed the femoral trochlear morphology in skeletally normal dogs using ultrasonography.
Results The intra- and interrater reliability for SAs measured using ultrasonography was good, and the correlation coefficient between SAs measured using ultrasonography and CT, or MRI, was strong. In skeletally normal dogs, the SAs for osseous contours decreased until 6 months of age. However, the SAs for cartilaginous contours did not change during the growth period.
Conclusion The ultrasonographic measurement method is reliable for the evaluation of femoral trochlear morphology in dogs. The contour of the articular cartilage surface of the femoral trochlea is already determined early in life, and ossification of the articular cartilage of the femoral trochlea proceeds until 6 months of age. The results of this study will provide crucial information for the evaluation of femoral trochlear morphology in dogs.
A History of Umbilical Vein Catheterization Does Not Preclude Children from a Successful Meso-Rex Bypass

Published: July 2023

Abstract
Introduction Umbilical vein catheterization (UVC) can cause portal venous thrombosis, leading to the development of extrahepatic portal venous obstruction (EHPVO) and portal hypertension (PHT). The feasibility of the Meso-Rex bypass (MRB) for the treatment of EHPVO in patients with a history of UVC has been questioned. We compared the feasibility of performing an MRB in patients with or without a history of previous UVC.
Methods A retrospective review of patients with EHPVO and known UVC status explored for a possible MRB at our institution was performed (1997–2022). Patients were categorized in two groups: with (UVC(+)) or without (UVC(–)) a history of UVC for comparison. A p-value less than 0.05 was considered significant.
Results One hundred and eighty-seven patients were included (n = 57 in UVC(+); n = 130 in UVC(–)). Patients in the UVC group were significantly younger at surgery and the incidence of prematurity was higher. Other risk factors for the development of EHPVO were similar between the groups, but only history of UVC could predict the ability to receive MRB (odds ratio [OR]: 7.4 [3.5–15.4]; p < 0.001). The success rate of MRB was significantly higher in patients with no history of UVC (28/57 [49.1%] in UVC(+) vs. 114/130 [87.7%] in UVC(–); p < 0.001). However, MRB patency at discharge (25/28 [89.3%] in UVC(+) vs. 106/114 [94.7%] in UVC(–); p = 0.3) was equally high in both groups.
Conclusion Our results indicate that a history of UVC is not a contraindication to MRB. Half of the patients were able to successfully receive an MRB. Patients with symptomatic PHT from EHPVO should not be excluded from consideration for MRB based on UVC history.

Published: July 2023

As biomolecules vibrate and rotate in the terahertz band, the biological effects of terahertz electromagnetic fields have drawn considerable attention from the physiological and medical communities. Ion channels are the basis of biological electrical signals, so studying the effect of terahertz electromagnetic fields on ion channels is significant. In this paper, the effect of a terahertz electromagnetic field with three different frequencies, 6, 15, and 25 THz, on the Kv1.2 potassium ion channel was investigated by molecular dynamics simulations. The results show that an electromagnetic field with a 15 THz frequency can significantly enhance the permeability of the Kv1.2 potassium ion channel, which is 1.7 times higher than without an applied electric field. By analyzing the behavior of water molecules, it is found that the electromagnetic field with the 15 THz frequency shortens the duration of frozen and relaxation processes when potassium ions pass through the channel, increases the proportion of the direct knock-on mode, and, thus, enhances the permeability of the Kv1.2 potassium ion channel.
Topic-based variation as both cognitive and agentive
Authors: Wan Tsung-Lun Alan 
Published: July 2023

AbstractTopic-based style-shifting refers to the variation pattern that, when people talk about a topic, they shift to a linguistic style which is associated with the topic. Most of the research on topic-based variation in read speech have not taken stance-taking into consideration. This study argues that stance-taking needs to be included in the analysis of topic-based variation, for reading something aloud is a practice where individuals engage with the message communicated in a text. This study looks at the socially salient variable /ʂ/ in Taiwan Mandarin, and how deaf speakers exploit this variable to perform their stances towards a passage concerned with the political relationship between hearing people and deaf signers. The findings show that participants who demonstrate a stance of deaf solidarity diverge from standard speech styles in their repertoires when reading the deaf passage.
Automated translation and pragmatic force
Authors: Valdeón Roberto A. 
Published: July 2023

Abstract
This article discusses the challenges that the rendering of the pragmatic implications of texts into a target
language posed for human translators and, by extension, for automated translation. It starts by discussing the importance of
pragmatics, focusing on two concepts that have received much attention on the part of pragmaticians as well as translation
scholars, namely implicatures and politeness. It moves to on to present some of the most notable publications on the interface
between pragmatics and machine translation. These illustrate that the interest in the pragmatic value of language has not
succeeded in advancing the integration of pragmatics into automated translation. Drawing on Kesckes and House, the last section
discusses two concepts to be considered regarding the role of pragmatics in intercultural mediation.
Neural machine translation and human translation
Authors: Sheng Anfeng , Kong Yankun 
Published: July 2023

Abstract
By comparing the Chinese, English and French versions of “Exhortations of Learning” and “On Building a Human Community with a Shared Future,” translated by human translators and the neural machine translation systems respectively, this essay finds out that human translators have addressed the political and ideological factors more tactfully while the working mechanism of the neural machine translation system lacks the formers’ judgment, consideration, flexibility and subjectivity. Moreover, unlike human translators, the neural machine system is not capable of activities such as summarizing the source texts, making comments or annotating. But on the other hand, the neural machine translation system has the advantages of its own. Not affected by bias like human translators, it could perform the translation faster and with a rather objective stance. All in all, there is still a long way to go before it can reveal the political and ideological factors in ways as human translators can achieve.
Indexicality across the boundaries of syntax, semantics and
pragmatics
Authors: Juul Nielsen Peter , Heltoft Lars 
Published: July 2023

Abstract
In Danish, indirect object (IO) constructions fall into two main
classes: (1) the three-argument valence-governed pattern and (2) the free
indirect object construction. The free IO is a constructional extension to
certain types of monotransitive constructions and verbs; by contrast, the
valence-governed IO is a manifestation of the third argument of three-place
verb stems in (prototypically) transfer constructions. The free indirect
object (free IO) in Modern Danish presents an intricate problem, calling for
concepts and solutions not normally connected with constructional syntax.
Its frequency is extremely low, and intuitions about its acceptability vary
according to basic speech act type. In assertive contexts, it comes across
as old-fashioned and is hardly productive; in regulative contexts, by
contrast, it retains full productivity. The few positive results yielded by
a corpus search are almost exclusively examples of free IOs in regulative
contexts.
Indexicality, as used especially in morphology by Henning Andersen
and Raimo Anttila, is the key concept of our analysis. An IO
np

must identify its argument by pointing indexically to some aspect of the
predicate’s semantics, but since – in the case of free IOs – there is no
third argument A3 in the verb’s valence schema, there is apparently nothing
for the free IO to index. In special cases, however, most importantly in
regulative contexts, the free IO finds an alternative indicatum by pointing
to features of the performative situation. Our findings indicate the need
for a grammatical theory that allows syntactic rules to be not only
semantically, but also pragmatically sensitive.
The dative alternation in German
Authors: Kholodova Alina , Allen Shanley E.M. 
Published: July 2023

Abstract
Many ditransitive events can be expressed in German using either
the indirect object construction (IOC) or the prepositional object
construction (POC). While most previous research on ditransitives in German
has focused on the IOC, very little attention has been paid to the much
rarer POC or to individual verb biases for the IOC vs. the POC. We
investigated structural preferences of native speakers of German using
elicited production and acceptability judgment studies. The results show
that the POC is not as restricted as previously thought, and that different
modalities (i.e., production vs. comprehension) reveal different aspects of
verb biases, which can be easily missed when relying on one type of
data.
Nonlinear energy harvesting via an axially moving piezoelectric beam with both d
31 and d
33 modes
Authors: Lu Ze-Qi , Chen Jie , Fu Hai-Ling , Ding Hu , Chen Li-Qun 
Published: July 2023

Abstract
Piezoelectric energy harvesters (PEHs) in the literature typically operate with a single conversion mechanism (either d
31 or d
33); the output power, therefore, is limited, and not sufficient to sustainably energize low-power electronics. In this study, a nonlinear PEH with coupled d
31 and d
33 modes is designed and evaluated. An axially moving piezoelectric beam (AMPB) was applied to investigate the contribution of d
31 and d
33 to the output, and the critical parameters of the configuration were determined. A distributed parametric electromechanical model was established to characterize the non-linear dynamics of AMPB with d
31 and d
33 modes. The Galerkin approach and the harmonic-balance approach were employed conjointly to investigate the forced response of the energy harvesting system. The axial velocity’s effects upon energy harvesting were as well discussed. Comparison of the frequency response functions (FRFs) for voltage and power output between energy structures of d
31 and d
33 modes revealed several discrepancies. For instance, the voltage and power output of the d
33 mode were greater than those of d
31 mode for low frequencies, and the difference between the two modes decreased as the frequency increased. For the composite mode d
31 and d
33, under the same parameter conditions, the voltage and power output were greater than the output of any single mode. The analytical results were supported by a numerical method through the finite difference method. Both analytical and numerical results indicated the FRF could be increased by increasing the excitation amplitude, reducing the damping coefficient, or increasing the electrode spacing. The present study showed the efficiency of the use of the FRF using nonlinear transverse vibration of AMPB for d
31 and d
33 modes.
High thermal conductivity insulating AlN/poly(m-phenylenedicarbonyl-m-phenylenediamine) paper realized by enhanced compatibility: a selection of appropriate coupling agent

Published: July 2023

Abstract
Encouraged by the goal of achieving net-zero carbon emission by 2050, the exploration of insulating material becomes one of the core projects to the electrical equipment innovations. The rise of composites enables the insulating material to be endowed with more functions. By this concern, adopting the coupling agents is one of the effective methods to improve the compatibility of composites, which highly strengthens the desired properties. The functional groups of coupling agents, nevertheless, could not always show a positive impact to access enhanced properties. In this work, four types of silane coupling agents including amino-propyl, glycidyletheroxy-propyl (GP), vinyl, and methacryloxy-propyl functional groups are employed to modify the aluminum nitride (AlN) fillers, and the modification effects on the insulating and thermal conductivity of the AlN/poly(m-phenylenedicarbonyl-m-phenylenediamine) (PMIA) composite paper are systematically investigated and compared. The results show that a proper coupling agent is beneficial to the uniform dispersion of the inorganic filler in the organic matrix and highly contributes to their interface quality, where the heat transfer path is established that boosts the heat dissipation. By tailoring the trap depth and density toward deeper and higher, the carrier transport is highly confined which enhances the breakdown strength to a large extent. Therefore, high breakdown strength and thermal conductivity of 182.9 kV mm−1 and 0.302 W (m·K)−1, respectively, are achieved in the GP modified AlN/PMIA paper, which are 16.7% and 167.4% higher than that of pure PMIA paper.
Comment on ‘Alpha decay of thermally excited nuclei’
Authors: Mohr Peter 
Published: July 2023

Abstract
In a recent study, Perez Velasquez, Caballero, and Kelkar report a dramatically enhanced α decay rate of the nucleus 212Po at high temperatures which reaches almost five orders of magnitude at a temperature of 2 Giga-Kelvin. Contrary to that finding, only a moderate enhancement by a factor of three is found in the present comment which is based on a careful study of the properties of excited states in 212Po.
Phase diagram and superconductivity of calcium alanates under pressure
Authors: Di Cataldo Simone , Boeri Lilia 
Published: July 2023

Abstract
In this paper we present a first-principles study of the high-pressure superconducting phase diagram of calcium alanates (Ca–Al–H), based on ab-initio crystal structure prediction and anisotropic Migdal–Eliashberg Theory. Calcium alanates have been intensively studied at ambient pressure for their hydrogen-storage properties, but their high-pressure behavior is largely unknown. By performing a full scan of the ternary convex hull at several pressures between 0 and 300 GPa, we identify several new structural motifs, characterized by a high Al–H coordination, where Al d orbitals participate in the bonding. Among all new phases thus identified, we focus in particular on a phase with CaAlH7 composition, which lies on the convex hull at 300 GPa, and remains dynamically stable down to 50 GPa, with a predicted superconducting T
c of 82 K, which likely represents a new promising template to achieve increase chemical precompression in ternary hydrides. Our findings reveal important insights into the structure-property relationships of calcium alanates under high pressure, and highlight a possible strategy to achieve conventional superconductivity at low pressures.
A new look at the sorption kinetics in reference gas standards
Authors: Persijn S T , Baldan A 
Published: July 2023

Abstract
The preparation of calibration gas mixtures in cylinders using the gravimetric method (ISO 6142-1) has enabled the production of a wide range of mixtures down to the pmol/mol level with low uncertainties reaching 0.01% relative and beyond. The gravimetric method has limited use however for reactive components that adsorb on the cylinder wall or valve. For such components the adage ‘what comes in = what comes out’ no longer holds. To quantify gas losses in cylinders due to adsorption on the inner surfaces, two methods are typically used: by comparison against other gas mixture preparation methods (e.g. dynamic methods) or by decanting part of a mixture in an identical cylinder followed by cross-comparison. Here we present a new method to elucidate the sorption dynamics based on the use of isotopes (here 12C-methanol and 13C-methanol isotopes). The amount fraction evolution of both isotopes in gas phase is followed in time using laser spectroscopic methods. This way, the kinetics of desorption (mainly 13C-methanol) and adsorption (12C-methanol) can be followed in time. In this paper we will present the results from a pilot study on methanol mixtures at trace amount fractions prepared in different cylinder materials and treatments.
