Published: September 2023

Abstract
Background Transpedicular screw (TPS) misplacement is still a nightmare for spine surgeons. Preoperative planning is one of the methods that a surgeon could use to minimize this complication. This study aims to compare the efficacy of three-dimensional (3D) and two-dimensional (2D) preoperative planning in posterior lumbar TPSs placement performed using the freehand technique.
Patients and Methods Patients who underwent posterior TPSs placement for degenerative lumbar spondylolisthesis or spinal stenosis using the freehand technique between November 2021 and October 2022 were evaluated retrospectively. In total, 33 and 30 patients who met the inclusion criteria were consecutively operated on with preoperative 2D and 3D planning, respectively. The patients were divided into the 2D preoperative planning group (2DG) and 3D preoperative planning group (3DG) and the two groups were compared.
Results Sixty-three patients were operated during the study period. There was no significant difference between the groups regarding blood transfusion, operation time, and radiation exposure. Although the accuracy of TPSs positioning was 94.2 and 96.5% in the 2DG and 3DG, respectively, the difference between the groups was not statistically significant. The upper facet joint violation rate was 12.8% (n = 20) in the 2DG versus 3.5% (n = 5) in the 3DG (p = 0.006). All L4 TPSs were inserted with their standard entry points without any modification (p < 0.0001; relative/risk ratio = 0.64). The modification rate was higher in L1, L2, and L5 TPSs (p < 0.0001; χ
2 = 24.7).
Conclusion For patients with degenerative lumbar diseases, 3D preoperative planning in posterior lumbar instrumentation surgeries performed with the freehand technique decreased the upper facet joint violation rate.

Published: September 2023

AbstractThe synthetic potential of unsymmetrically substituted aryne intermediates is significantly hindered by regioselectivity issues. Current methods for inducing regioselectivity all rely on substrate control and are focused on non-metallated arynes. Before our initial disclosure, there was no systematic study regarding the regioselectivity of metal-catalyzed aryne reactions. By exploiting ligand control, we have induced regioselectivity in a palladium-catalyzed aryne annulation to form phenanthridinones (up to 9:91 r.r.). Through this study we have investigated: ligand effects, influence of steric perturbation, and the impact of the aryne precursor.1	Introduction2	Inducing Regioselectivity via Ligand Control3	A Comparison of o-Borylaryl Triflate Aryne Precursors to Kobayashi Aryne Precursors4	Conclusion
Pd-Catalyzed Intramolecular Cyclization–Thiocarbonylation Cascade Using Thioesters
Authors: Nakada Masahisa , Ito Ryunosuke , Okura Yoshifumi 
Published: September 2023

AbstractA Pd-catalyzed intramolecular cyclization–thiocarbonylation cascade using thioesters is described. The developed cascade reaction afforded chromane, coumaran, indoline, and oxindole derivatives with a chiral quaternary carbon atom at the benzylic position in high to excellent yields. Relative to those observed in the previously reported relevant cascade using TIPSSPh, the yields with thioesters are almost the same or higher, depending on the substrate. Moreover, the use of thioesters significantly reduces the reaction time to less than one hour. Therefore, AcSPh is advantageous over TIPSSPh in terms of reaction time, atom economy, and cost effectiveness.
Indirect Anterior Restorations with no-prep technique: Aesthetic and Biological Effectiveness
Authors: Pappalardo Alfio , Fiorillo Luca , Catalano Francesco , Cervino Gabriele 
Published: September 2023

AbstractThe aesthetic result in the ceramic restoration of anterior teeth has always been a challenge in clinical practice and, in these cases, success depends on the skills of both the clinician and the dental technician. In current dentistry, the main objective is to pursue aesthetic results while preserving biological structures. Among the various conservative techniques available for anterior restorations, veneers are the most advantageous, compared to traditional crown preparation, both for the amount of tooth structure preserved in the preparation phase and for the direct adhesion on the enamel in the cementation. This article presents a clinical case of no-prep porcelain veneers (no-prep technique) for smile frame restoration.
Robotic Nerve Surgery: Brachial Plexus

Published: September 2023

AbstractManagement of closed brachial plexus injuries has traditionally favored conservative approaches with lengthy intervals between initial injury and surgical reconstruction. The complex anatomy of this region often requires large incisions with extensive dissection. Recently, the use of robotic systems in plastic and reconstructive surgery has been increasing, and robot-assisted brachial plexus reconstruction is a novel application that is currently being explored. Current literature describing this application is primarily comprised of feasibility studies using animal and cadaver models, and literature describing use in human subjects is limited. Advantages demonstrated by these early studies include the reduction of physiologic tremor, 3D visualization of anatomical structures, and ergonomic positioning; this allows for increased surgical dexterity and the ability to perform minimally invasive microsurgical procedures within the confined anatomical spaces of the brachial plexus. Limitations revolve around inadequate instrumentation, large learning curves, and increased costs that restrict the ability to perform these complex microsurgical procedures reliably and efficiently. As companies continue to develop instrumentation specific to robot-assisted microsurgery, more extensive longitudinal studies outlining long-term costs, changes in operating time, and functional outcomes will be required before a conclusion about the utility of these systems in brachial plexus surgery can be made.
Anterior Cruciate Ligament Rupture Combined with Complete Radial Tear of the Posterior Horn of the Lateral Meniscus: Suture or Resection?

Published: September 2023

AbstractAnterior cruciate ligament (ACL) rupture often presents with a tear of the posterior horn of the lateral meniscus. There is no clear preference between ACL reconstruction with suture and resection of the meniscus. We aimed to compare the clinical efficacy of ACL reconstruction with suture versus resection in patients presenting with arthroscopic ACL rupture and radial complete tear of the posterior corner of the lateral meniscus. We retrospectively analyzed 157 patients with ACL rupture and complete radial tear of the posterior horn of the lateral meniscus. Between May 2010 and April 2015, 86 of 157 patients underwent ACL reconstruction and meniscus suture (study group, 54.78%) and 71 of 157 patients underwent ACL reconstruction and meniscus resection (control group, 45.22%) in our department. All patients were monitored over the 12 to 72-month follow-up period. The primary evaluation indices were the Lysholm scores, the International Knee Documentation Committee (IKDC) scores, pivot shift test, the Barret criteria, and magnetic resonance imaging (MRI) findings of meniscal healing. The majority of 157 patients were relatively young men (29.64 ± 7.79 years) with low body mass index (BMI) (23.79 ± 2.74). The postoperative Lysholm and IKDC scores of the two groups were significantly improved over the corresponding preoperative scores (p < 0.05). The clinical results and excellent and good rates were significantly better for the study group than for the control group (both, p < 0.05). MRI showed that the meniscal healed rate of the study group was 96.51%. There was no significant difference in BMI between subgroups for any functional outcome. For patients with ACL rupture and complete radial tear of the posterior horn of the lateral meniscus, ACL reconstruction and both simultaneous suture and resection of the posterior horn of the lateral meniscus were found to be safe and effective. There was no association between outcomes and BMI. However, the former was associated with a superior long-term clinical effect and may restore the integrity of the meniscus and is particularly recommended for young patients.

Authors: Mhirig Ibtissam , Harrar Sara , Habibi Leila , Sayagh Sanae , Aboulmakarim Siham 
Published: September 2023

Objectives:
Complete blood count parameters have gained renewed interest as predictors of endothelial dysfunction in type 2 diabetes mellitus (T2DM). Thus, the aim of this study was to observe the changes in platelet and erythrocyte parameters between diabetics and nondiabetics and to evaluate these changes in relation to glycemic control.

Materials and Methods:
This cross-sectional study was performed in Mohammed VI University Hospital, Marrakech, Morocco, from January 2020 to July 2021. A total of 307 Moroccan patients were enrolled in this study, which included 222 diabetic patients and 85 nondiabetics. The diabetic patients were divided into two groups A (hemoglobin A1c [HbA1c] ≤ 6.5%) and B (HbA1c < 6.5%) according to their glycated hemoglobin levels (HbA1c). Biological parameters were processed as per the standard technique. Data analysis was performed using SPSS statistical software.

Statistical Analysis:
Data were analyzed using SPSS 23 software (Statistical Package for Scientific Studies; IBM Corp. Armonk, New York, United States), and it was described as mean and standard deviation.

Results:
A significant difference was mentioned regarding mean corpuscular volume (MCV) (p < 0.001), red blood cell distribution width (RDW) (p < 0.001), and volume/platelet count (p = 0.023) between diabetics and nondiabetics. MCV and RDW were lower in group B than group A (p = 0.004; p = 0.04), while MPV was higher (p = 0.342). RDW significantly and negatively correlated with HbA1c in diabetic population (r = –0.182; p = 0.006). On the other hand, a significant and positive correlation between MPV and HbA1c was mentioned (r = +0.184; p = 0.006).

Conclusion:
Our study showed that RDW and MPV correlate with HbA1c in T2DM and can be used as a reproducible and inexpensive means to ensure proper control of glycemic status. Further studies are warranted to define specific RDW and MPV values predictive of complication risk in the diabetic population.
Surviving in a male academia: gender gap, publication strategies and career stage in South European political science journals
Authors: Bosco Anna , Verney Susannah , Bermúdez Sandra , Tonarelli Annalisa 
Published: September 2023

AbstractWomen’s underrepresentation in top political science journals has been a central concern of both the American Political Science Association and the European Consortium of Political Research, which have promoted studies to assess the extent and features of the gender gap. However, so far in Southern Europe, research on this topic has been scarce. Our work adds to the literature by presenting new data on three journals: the Italian Political Science Review, the Spanish Political Science Review and South European Society and Politics. The research has three main goals: to gauge the gender gap in the three journals; to examine whether gender influences publication preferences; and to investigate how career intersects with gendered publication strategies. The analysis is built on a database of almost 800 articles and about 1400 authors, published in these three journals in 2011–2022. Our main findings are that South European journals reveal a gender gap similar to other international journals, where just one-third of authors are women; that this publication gap is accompanied by gendered publication strategies; and that the routes men and women follow to succeed in academic publishing diverge at every career stage. Finally, we argue that women's preferred strategies may not offer the optimum path to career success.
Performance study of a valveless piezoelectric pump with built-in semi-arc bluffbody antique tower channel
Authors: Hu Renhui , Wang Chensheng , Hou Yi , Hu Dianbin , He Lipeng 
Published: September 2023

According to the bluffbody bypass effect, the irregular bluffbody can be used to improve the valveless piezoelectric pump. This paper designs a semi-arc bluffbody based on the bluffbody bypassing principle to alleviate the phenomenon of fluid backflow. The fluid passes through the shape of the antique tower to further enhance pumping efficiency. A positive fluid flow mechanism in the pump cavity is theoretically derived. The simulation of the velocity and pressure distribution in the tower-shaped channel of the pump cavity leads to the conclusion that the forward flow has better performance than the reverse flow, and the correctness of the theory is also verified. Experiments further proved that the volume of fluid in the forward direction was reduced by 10.8% when compared to the reverse direction. The study of the height of different semi-arc bluffbody and the angle of the tower trough shows that as the height and angle increase, the flow rate grows first and then reduces. The maximum flow rate is 243.83 ml/min when the bluffbody height is 4 mm and the channel angle is 20° (220 V, 85 Hz).
On the chemistry of small waterbodies linked to marine aerosols and local geology on the Windmill Islands and mainland near Casey Station, Antarctica

Published: September 2023

Context In total, 43 shallow waterbodies were sampled in 1983 in the vicinity of Casey Station and nearby islands in Antarctica. The following physico-chemical parameters were obtained: water and air temperature, pH, conductivity, dissolved oxygen, plus major and minor elements. Aims To identify the physico-chemical characteristics of these waters and determine their origin, and calculate their mineral saturation indices. Methods Waters were analysed using standard methods, including for some elements, flame-atomic absorption spectrometry, spectrophotometry, ion chromatography and gravimetric determination. Mineral saturation indices were calculated using the PHREEQ program. Key results Water salinities were generally low and in the range of 120–1200 mg L−1 (total dissolved solids, TDS), except for one site connected to the sea, and four slightly saline sites. The Na/Cl, Cl/Br and Ca/SO4 ratios of several waters were in the vicinity of seawater ratios, implying a contribution of marine aerosols. However, the Mg/Ca ratio of most waters departed from the seawater ratio, plus there was concordance between the molar ratios of (Na + K)/(Ca + Mg) of many of the waters sampled and those calculated from rock geochemical analyses from diverse lithologies. Such chemical ‘provincialism’ appears to be dictated by rock composition. Nitrate and phosphate concentrations were high in the vicinity of penguin rookeries. Conclusions Two sources of ions are identified, one as marine aerosols as shown by three sets of ratios (Na/Cl, Cl/Br and Ca/SO4) with known marine values, and the other from the weathering of local rocks as shown by (Na + K)/(Ca + Mg) of the lake waters compared to the same ratios for the surrounding rocks. Only a few waterbodies have saturation levels for several carbonate minerals (calcite, aragonite, dolomite and rhodochrosite). Implications Future work is recommended for monitoring the waterbodies surrounding Casey Station as a result of the increased atmospheric CO2 concentration that has occurred over the past 40 years, and likely also with the cessation of building activities around Casey Station.
Novel acoustic lure methodology facilitates detection of the cryptic ghost bat at a landscape scale
Authors: Ruykys Laura , Hanrahan Nicola , Stokeld Danielle 
Published: September 2023

Context The conservation of the threatened ghost bat (Macroderma gigas) is currently hampered by a lack of standardised survey methodology for detecting the species away from known roosts. The low amplitude of the species’ echolocation call, together with only sporadic production of social calls while foraging, means that acoustic detection is unreliable. However, the ghost bat is known to be physically responsive to full-spectrum playback of its own social calls when these are broadcast in close vicinity (~100 m) to known roosts. Aims Using a two-phase investigation, we aimed to establish whether playback could be used to detect ghost bats away from the roost, in open woodland habitat in the Northern Territory. Methods In phase one, a trial of paired (active treatment and control) call playback experiments was conducted at three distances (1 km, 2.5 km and 5 km) from four known roosts using the ghost bat’s ‘squabble’ social vocalisation. Call playback, distance, roost and moon phase were used as explanatory variables in an information-theoretic approach using generalised linear models. In phase two, a 65 010-ha survey area was broken into a grid of adjacent hexagons with centroids spaced 5 km apart; replicate surveys using call playback were conducted at each centroid. An occupancy model was used to determine detection probability for the method in the survey area. Key results Ghost bats were successfully detected. In phase one, one model had substantial support and this contained only one variable: that of the presence or absence of the ‘squabble’ vocalisation. In phase two, ‘hotspots’ of ghost bat activity were detected in a region for which records were scant and predominantly historical. The occupancy model identified that 72% of sites were occupied and established a detection probability of 0.505, which provided a cumulative probability of 0.75. Conclusions Our results show that call playback is a reliable method of detecting the cryptic and threatened ghost bat at a landscape scale in the Northern Territory. Implications We suggest that call playback could be used as a standardised survey technique across the range of the ghost bat.
Balancing social determinism vs. sound change
Authors: Burns Roslyn 
Published: September 2023

Abstract
This paper investigates the relationship between social and phonetic motivations for language change in Fang (Bantoid). While previous research has proposed that innovations in Fang arose due to social need and lack phonetic motivation (Mve et al. 2019; Good, Di Carlo & Tschonghongei 2020), I propose that there is a phonetic motivation and the social situation, at best, was a pathway for the innovation to gain wider adoption in the population. I provide comparative and language-internal evidence that the Fang innovations are driven by two interconnected processes, palatalization and spirantization, triggered by high vowels. These processes have been obscured synchronically in part due to the phonemic merger of *i > ə in some parts of the paradigm, thus making the alternations look phonetically unmotivated.
Yes(Rom.Da). Usages and functions in L2 proficiency examinations
Authors: Vasilescu Andra 
Published: September 2023

AbstractThe article analyses a Romanian corpus of intercultural dialogues recorded in natural settings during language proficiency examinations and discusses the usages of the frequently occurring wordyes(Rom.da). The framework is provided by the Mixed Game Model (Weigand 2009,2010,2017,2018, among others) intersected with the socio-cognitive approach to intercultural communication (Kecskes 2007,2008,2010,2013, among others). Beyond the analysis of a single lexical unit in a limited collection of texts, the author aims to demonstrate how a particular word of the lexicon becomes a culturally-socially-cognitively-discursively-rhetorically situated utterance that acquires specific functions when it is used by interlocutors who negotiate their communicative agendas to come not only to mutual understanding but also to achieve their convergent-divergent institutional purposes.
Military metaphors in the discourses of the pandemic in two post-Yugoslav states
Authors: Bogetić Ksenija 
Published: September 2023

Abstract
The present study contributes to the growing body of work on the pandemic-time use of the war metaphor in
public discourse, by focusing specifically on military metaphors in the media discourses of two post-Yugoslav, post-conflict
states. Using the approach of Critical Metaphor Analysis, the paper explores the discursive realizations of the war
metaphor in this context, with a particular focus on metaphor extension, metaphor entailments, and effects of earlier conflict
memory on discursive use of the metaphor. The results show how metaphor entailments may vary according to the kinds of war made
salient in discourse. Several forms of discursive use grounded in linking metaphorical and literal senses of war are identified,
as creating specific local meanings, which in the case area observed worked to relate representations of threat to dominant
instrumentalizations of historical memory and ongoing nationalist discourses. Beyond the local context, the findings are used to
discuss some aspects of pandemic-time war metaphor use important both for the theorizing of adversarial metaphors in
public discourse, and for more nuanced analyses of the discourses of crisis.
Printed and flexible organic and inorganic memristor devices for non-volatile memory applications
Authors: Jaafar Ayoub H , Gee Alex , Kemp N T 
Published: September 2023

Abstract
The electronics market is highly competitive and driven by consumers desire for the latest and most sophisticated devices at the lowest cost. In the last decade there has been increasing interest in printing electronic materials on lightweight and flexible substrates such as plastics and fabrics. This not only lowers fabrication and capital costs but also facilitates many new applications, such as flexible displays and wearable electronics. The printing of computer memory is also desirable since many of these applications require memory to store and process information. In addition, there is now an international effort to develop new types of computer memory that consume ultra-low levels of power. This is not only to lower energy usage worldwide, which is important for reducing CO2 emissions, but it also enables a longer period between the re-charging of devices such as mobile phones, music players and fitness bands. Memory that is non-volatile is an obvious choice since it does not consume power to retain information like conventional SRAM and DRAM. Memristors (or memory resistor) are a new type of memory that are intrinsically non-volatile in nature. Their simple two-terminal architecture, easy method of fabrication and low power consumption means they have received much attention from both the research community and industry. Devices with the lowest fabrication costs are made from organic or hybrid (organic–inorganic) composite materials because of the ability to use low-cost solution processing methods with the advantages of large area deposition under vacuum-free and room temperature ambient conditions. Memristors have excellent device properties, including a large resistance Off/On ratio (up to 5 orders of magnitude), fast switching speeds (less than 15 ns), long endurance (over 1012 cycles), long data storage retention time (∼10 years) and high scalability down to nanoscale dimensions. In this article we review progress in the field of printed and flexible memristor devices and discuss their potential across a wide range of applications.
