Contesting the Concept of Timeline in African Traditional Music-Dance: Perspectives from Ghana
Authors: Addaquay Alfred Patrick
Published: July 2023

The term timeline in Sub-Saharan African traditional music has been treated by several scholars in diverse ways. However, there are other dimensions to the so-called timeline beyond the constant point of reference as described by Nketia. The foremost challenge that this paper seeks to address is the fact that the term has been restricted and needs to be expanded. Consequently, it is obvious that the main goal of the entire paper is to re-examine the term Timeline. Data was gathered by listening to live performances, rehearsals, interviews, and various online performances including Zoom meetings with performers, and observing YouTube, Facebook and other platforms for critical analysis and comparative study of various dance styles from different parts of Ghana, as well as existing literature on the subject matter. Overall, the paper argues that the definitions and discussions about the concept by a couple of scholars ought to be amended and also elaborated for a deeper understanding upon further research. This will serve as a continuous discussion by other scholars and moreover, some of the confrontational approaches or arguments may help future generations to build on the discussion for the benefit of posterity.

Kwesi Gyan: A Cross-Cultural Artistic Impression on Apatampa Musical Resources
Authors: Dawson Nana Amowee
Published: July 2023

Interculturalism has played a significant role in influencing societies’ artistic identity, particularly in Africa’s music. This phenomenon seems to be no exception in the choral, art-song, and instrumental music spheres despite the untapped nature of orchestral music in this part of the world, especially among Ghanaian art/scholar musicians. Orchestral music as a genre in the Neo-African art music space appears deficient in terms of its usage of African resources for creation. The less-to-zero exploitation of this art form has roughly marked a gap in its ingenuous disposition; thus, affording the opportunity for similar works. “Kwesi Gyan”, the 3rd Movement of the ‘Sankɔfa Symphony’ is a 21st-century chamber orchestra piece that merges traditional rhythms and a folk tune from Apatampa music with scholarly compositional techniques. The orchestral form of this music speaks to its Western nature. Likewise, the main melodic and rhythmic structures originate from Ghanaian culture, which illustrates the concept of interculturalism through the aforementioned merger. This paper presented the composition through a practice-based research approach, drawing on theories of cross-cultural music-making and Neo-African art music. It also provided a deeper understanding of the composer’s thought process and provides insight into understanding the piece. Additionally, the article aimed at inspiring creative research into Ghanaian musical arts, potentially contributing to the preservation of the country’s cultural heritage for future generations.

On 2020 April 19–20, a solar ejection was seen by spacecraft in a radial alignment that included Solar Orbiter and Wind. The ejection contained a magnetic flux rope where magnetic field and plasma parameters were well correlated between spacecraft. This structure is called an “unperturbed magnetic flux rope” (UMFR). Ahead of the UMFR is a portion of the ejection (not sheath) that is referred to as “upstream” (US). We focus on the US and inquire why the correlation is so much weaker there. Specifically, we analyze data collected by Solar Orbiter at 0.81 au and Wind at L1. We show that a plausible cause for the lack of coherence in the US is a combination of front erosion and internal reconnection occurring there. Front erosion is inferred from an analysis of azimuthal magnetic flux balance in the UMFR. In the present case, we contend that the US, rather than the UMFR, is the source of the eroded field lines. The presence of erosion is supported further by a direct comparison of the magnetic field data at both spacecraft that shows, in particular, a massive shrinkage of the front portion of the US. Internal reconnection is also happening at thin current sheets inside the US. Strong nonradial flows are reconfiguring the structure. As a result of these reconnection processes, a whole section of the US is disrupted and field lines move down the flanks of the ejection and out of view of Wind.
Asteroseismic Investigation on KIC 10526294 to Probe Convective Core Overshoot Mixing
Authors: Zhang Qian-Sheng , Li Yan , Wu Tao , Jiang Chen
Published: July 2023

In the overshoot mixing model with an exponentially decreasing diffusion coefficient, the initial value of the diffusion coefficient plays a crucial role. According to the turbulent convective mixing model, the characteristic length of convection in the convection zone differs from that in the overshoot region, resulting in a rapid decrease of the diffusion coefficient near the convective boundary. To investigate this quick decrease, we conducted an asteroseismic study on the intermediate-mass slowly pulsating B-type star KIC 10526294. We generated stellar models with varied input parameters, including the overshoot parameters, and compared the resulting stellar oscillation periods with observations. To mitigate the potential issue arising from large steps in the stellar parameters and stellar age, we employed a comprehensive interpolation scheme for the stellar oscillatory frequencies, considering all stellar parameters and stellar age. Our analysis revealed that the quick decreasing of the diffusion coefficient has discernible effects on the stellar oscillations, and a quick decrease with 4 orders of magnitude shows the best oscillatory frequencies compared with the observations. This provides weak evidence in support of the prediction made by the turbulent convective mixing model. Furthermore, we examined the residuals of the oscillation periods and discovered a potential association between abundance anomalies in the buoyancy frequency profile and the oscillation-like patterns observed in the residuals.

Unbiased sky background modeling is crucial for the analysis of deep wide-field images, but it remains a major challenge in low surface brightness astronomy. Traditional image processing algorithms are often designed to produce artificially flat backgrounds, erasing astrophysically meaningful structures. In this paper, we present three ideas that can be combined to produce wide-field astronomical data that preserve accurate representations of the background sky: (1) Use of all-sky infrared/submillimeter data to remove the large-scale time-varying components while leaving the scattered light from Galactic cirrus intact, with the assumptions of (a) the underlying background has little power on small scales, and (b) the Galactic cirrus in the field is optically thin on large scales; (2) Censoring of frames contaminated by anomalously prominent wings in the wide-angle point-spread function; and (3) Incorporation of spatial covariance in image stacking that controls the local background consistency. We demonstrate these methods using example data sets obtained with the Dragonfly Telephoto Array, but these general techniques are prospective to be applied to improve sky models in data obtained from other wide-field imaging surveys, including those from the upcoming Vera Rubin Telescope.
Dynamic Formation of a Transient Jet from Arched Magnetized Laboratory Plasma
Authors: Sklodowski Kamil D. , Tripathi Shreekrishna , Carter Troy
Published: July 2023

A laboratory plasma experiment was built to explore the eruptive behavior of arched magnetized plasmas with dimensionless parameters relevant to the Sun’s photosphere (β ≈ 10−3, Lundquist number ≈104, plasma radius/ion gyroradius ≈20, ion–neutral collision frequency ≫ion cyclotron frequency). Dynamic formation of a transient plasma jet was observed in the presence of the strapping magnetic field. The eruption leading to the jet is unintuitive because the arched plasma is both kink- and torus-stable. The jet structure erupts within a few Alfvén transit times from the formation of the arched plasma. Extensive measurements of plasma temperature, density, magnetic field, and flows are presented. In its early stages, the jet plasma flows away from the arch with supersonic speeds (Mach 1.5). This high-speed flow persists up to the resistive diffusion time in the arched plasma and is driven by large gradients in the magnetic and thermal pressures near the birthplace of jets. There are two distinct electric current channels within the jet, one consisting of outgoing electrons and another composed of electrons returning to the anode footpoint. Significant current density around the jet is a consequence of the diamagnetic current produced by a large thermal pressure gradient in the jet. Ion–neutral charge-exchange collisions provide an efficient mechanism to produce the cross-field current and control the dynamics of the complex current channels of the jet.

Published: July 2023

The 21st century has seen significant changes in the way enterprises operate and are managed. One of the most important key trends was digital transformation, which has had a profound impact on enterprises, forcing them to transform their operations to become more agile, efficient, and customer focused. Despite its many benefits, this digital transformation has not yet fully entered the traditional sector such as the furniture one. Hence, the main purpose of this chapter was to present how what factors could affect the integration of 4.0 technologies by Spanish companies from the furniture sector. The Tornatzky and Fleischer's Technology-Organisation-Environment model and an in-depth study of the art of the furniture sector were used to define these factors. Based on those factors, the author has been conducting comprehensive research in Spanish furniture sectors companies using interviews. From this conducted research, it can be concluded that the organisational factors influence the adoption of 4.0 technologies more than environmental or technological factors.

Published: July 2023

With the development of digitalization and Internet technology, enterprise information security is facing more and more challenges. Many enterprises have begun to adopt big data (BD) and artificial intelligence (AI) technology for risk assessment (RA) and prediction to effectively manage information security risks. This article discusses the application of BD and AI technology in enterprise information security management (ISM) and RA from two aspects. Firstly, the mobile payment signature scheme based on number theory research unit is used to improve the security of the mobile payment system. This scheme uses lattice algorithms to achieve fast key generation, signing, and verification and can resist traditional cryptographic attacks. Secondly, a set of enterprise ISM and RA system is established, including risk identification, RA, monitoring and early warning, emergency response, and other links. BD and AI technology is used to analyze internal and external data to provide accurate RA results to achieve automated RA.

Published: July 2023

Electrical transport in materials have been studied extensively due to its great potential in spintronic technology. The introduction of the secondary phase into the manganite matrix can modify the electrical properties, subsequently improving the low-field magnetic resistance (LFMR). In this work, we study the change in electrical properties at different temperatures of polycrystalline (1-x)La0.7Sr0.2Ca0.1MnO3/xTiO2 (LT) composites where x = 0, 0.05 and 0.1. Polycrystalline La0.7Sr0.2Ca0.1MnO3 (LSCMO) was synthesized by sol-gel method, calcined at 700 °C, and pre-sintered at 800 °C for 6 h before adding TiO2. TiO2 as filler was mixed with LSCMO by wet mixing and stirring for about 30 min until a homogeneous compound was formed. Composite LT was then inserted to oven up to 100 °C for 2h to remove the moisture, compacted at 10 MPa, and sintered at 1200°C for 12 h. All samples in the LSCMO phase have a rhombohedral crystal structure with space group R3c. The crystal structure parameters were studied using Rietveld refinement through GSAS II software. The sample was characterized by SEM to represent the morphology of the sample. As the TiO2 content increased, the magnetization decreased, as observed by VSM analysis at room temperature. The electrical transport properties of pure LSCMO and LT were characterized by cryogenic from 195K to 260 K. The resistivity of LT10 is too high compared to that of LT5 and as the temperature increases, the resistivity in this range will decrease. For 200 K, the resistivity of LSCMO, LT5 and LT10 are 3.09 x 10-2 ohm.cm, 4.40 x 103 ohm.cm and 4.77 x 104 ohm.cm respectively.

Published: July 2023

Copper-Nickel-Tin alloys have been recently developed by Hardening due to spinodal decomposition. The (Cu - 9Ni - 6Sn) system has shown promise in this direction and has been used to develop several high strength compositions. It is well known the fact that small element additions significantly modify phase transformation characteristics, the effect of adding Silicon or Silver on the Spinodal hardening in (Cu - 9Ni - 6Sn) alloy was studies close to the Spinodal cusp temperature. The presence of Silver also increased the ductility of alloy at the expense of some hardness. The effects of trace elements additions have been observed in this work with a view to improve high strength alloys as substitutes to the Copper – Beryllium alloys. The results obtained from the current research proved that adding a small amount of alloying elements with a percentage (1%) of silicon or silver to the base alloy (Cu - 9% Ni - 6% Sn), led to the stability of the mechanical properties resulting from the stability of the microstructure due to Heat treatment for hardening (Spinodal decomposition).

Nanosilica is a nanotechnology product with many substantial functions in many industries. Previous research showed that nano silica can be synthesized from geothermal silica, that caused silica scaling in injection well and turbine in geothermal power plant, reducing its power plant capacity by 40%. This research used geothermal silica as a precursor for nanosilica production with co-precipitation to recover amorphous silica from silica geothermal to reduce scaling while also increasing its economic value. The objectives of this study were to determine the model to represent the co-precipitation method for nano-silica by using nucleation and growth modelling, therefore help the scale-up process of nanosilica production. The experiment was conducted in four steps. (1) Silica washing utilized distillate water with a ratio of water to silica of 10:1 and sulfuric acid of 20% with a ratio of acid to silica of 4:1, both as a washing agent. (2) Preparation of HCl with concentrations of 3% and 9%. (3) Preparation of sodium silicate solution by reacting washed silica and NaOH to obtain sodium silicate. (4) Preparation of primary and secondary sodium silicate by diluting sodium silicate by two and four times to obtain primary and secondary sodium silicate, respectively. (5) Precipitation of sodium silicate with HCl consists of two steps using primary and secondary sodium silicate. The result showed that the model fit concentration data, with Sum of Squared Error (SSE) 1.9297.10-4, mass transfer coefficient rate is 9.8.10-3 dm/min, and the average relative error is 3.5%.

Published: July 2023

Aviation statistics identify collision with terrain and obstacles as a leading cause of helicopter accidents. Assisting helicopter pilots in detecting the presence of obstacles can greatly mitigate the risk of collisions. However, only a limited number of helicopters in operation have
an installed helicopter terrain awareness and warning system (HTAWS), while the cost of active obstacle warning systems remains prohibitive for many civil operators. In this work, we apply machine learning to automate obstacle detection and classification in combination with commercially available
airborne optical sensors. While numerous techniques for learning-based object detection have been published in the literature, many of them are data and computation intensive. Our approach seeks to balance the detection and classification accuracy of the method with the size of the training
data required and the runtime. Specifically, our approach combines the invariant feature extraction ability of pretrained deep convolutional neural networks (CNNs) and the high-speed training and classification ability of a novel, proprietary frequency-domain support vector machine (SVM) method.
We describe our experimental setup comprising the CNN + SVM model and datasets of predefined classes of obstacles—pylons, chimneys, antennas, TV towers, wind turbines, helicopters—synthesized from prerecorded airborne video sequences of low-altitude helicopter flight. We analyze
the detection performance using average precision, average recall, and runtime performance metrics on representative test data. Finally, we present a simple architecture for real-time, onboard implementation and discuss the obstacle detection performance of recently concluded flight tests.

The autophagy process recycles dysfunctional cellular components and protein aggregates by sequestering them in autophagosomes directed to lysosomes for enzymatic degradation. A basal level of autophagy is essential for skeletal muscle maintenance. Increased autophagy occurs in several forms of muscular dystrophy and in the merosin-deficient congenital muscular dystrophy 1A mouse model (dy3k/dy3k) lacking the laminin-α2 chain. This pilot study aimed to compare autophagy marker expression and autophagosomes presence using light and electron microscopes and western blotting in diagnostic muscle biopsies from newborns affected by different congenital muscular myopathies and dystrophies. Morphological examination showed dystrophic muscle features, predominance of type 2A myofibers, accumulation of autophagosomes in the subsarcolemmal areas, increased number of autophagosomes overexpressing LC3b, Beclin-1 and ATG5, in the merosin-deficient newborn suggesting an increased autophagy. In Duchenne muscular dystrophy, nemaline myopathy, and spinal muscular atrophy the predominant accumulation of p62+ puncta rather suggests an autophagy impairment.

In 2017, Global Initiative for Chronic Lung Disease (GOLD) made substantial changes to its ABCD group categorization. Although several studies had been conducted to assess the impact of the new GOLD category, there was no research on the change of the GOLD classification in Vietnam. This retrospective analysis was conducted at Asthma and COPD clinic at the University Medical Center in Ho Chi Minh City, Vietnam. Our study population comprised patients visiting Medical Center from January 2018 to January 2020. We categorized patients’ demographic, clinical characteristics and pharmacotherapy based on GOLD 2011 and 2017 guidelines. A comparison between the two versions was also determined. A total of 457 patients were included in this study. The percentage of groups A, B, C and D according to GOLD 2011 was 5%, 20.8%, 13.1% and 61.1%; and according to GOLD 2017 was 6.1%, 34.1%, 12% and 47.8%, respectively. In terms of gender, male patients constituted nearly 95% of the study’s population (433/457 patients). Regarding pharmacotherapy, approximately 20% of the low-risk group (group A-B) was overtreated with ICS components: LABA+ICS (15.8%) and LAMA+LABA+ICS (3.8%). There were 13.3% and 1.1% of patients transferred from D to B and from C to A, respectively. All of them had lower FVC% pred, FEV1% pred and FEV1/FVC than the patients remained in group B or A (p<0.005). This is the first research in Vietnam to show the distribution of COPD patients using both the GOLD 2011 and GOLD 2017 criteria. There was 14% of patients reclassified from high-risk groups to low-risk groups when changing from 2011 to 2017 version and discordance of medications between guidelines and real-life practice. Therefore, clinicians should use their clinical competence to consider patients' conditions before deciding the appropriate therapeutic approach. Consequently, further studies were required to evaluate the effect of the change in GOLD classification.
Effect of gender on medical students’ clinical learning experience in a multicultural setting
Authors: Mohammed Ghada , Bennett Deirdre
Published: July 2023

Background:

The clinical clerkship learning experience is a critical aspect of medical education; it can be affected by various factors, including gender. Understanding the effect of gender on this experience requires a deeper analysis and exploration of students’ perceptions. This study aims to investigate medical students’ perceptions of the effect of gender on the clinical clerkship learning experience in a multicultural setting.

Methods:

This qualitative study purposefully sampled medical students in their final year who had clerkship experience. Semi-structured face-to-face interviews (n = 16) were conducted. NVIVO software (QSR NVivo 11) was used for the thematic analysis.

Results:

Male students perceived facing more difficulties and rejection from female patients. Consequently, they felt demotivated, as their participation in the clinical examination of female patients was negatively affected. Female students revealed that their male colleagues had an established idea of not being allowed to examine female patients, and thus did not try. A gender barrier with patients of the opposite gender is related to multiple factors such as culture and religion. The influence of gender on clinical supervision had mixed outcomes. Some students reported positive experiences, while others reported negative ones. The students believed that their culture, religion, and personal beliefs did not influence their relationship with patients.

Conclusion:

This study highlights the significant effect of gender on the clinical clerkship learning experience in the United Arab Emirates. To ensure an adequate and healthy learning environment, solutions to overcome these challenges must be developed.
Stomatin-Like Protein-2 Contributes the Migration and Invasion of Breast Cancer Cells via Regulating ERK/FOXO3a Signaling Pathway
Authors: Wu Shengming , Zhao Lingang , Li Qian
Published: July 2023

Breast cancer (BC) is the most common tumor in women, and its incidence is increasing, ranking first among female malignant tumors. It is urgently needed to find new and reliable biomarkers of BC and to understand the cellular changes that cause metastasis. Stomatin-like protein-2 (SLP-2) is a member of the stomatin protein superfamily. Studies have shown that SLP-2 was highly expressed in some tumors and played an important role in tumor genesis and development. SLP-2 regulated the extracellular signal-regulated kinase (ERK) pathway, and activation of ERK phosphorylated FOXO3a, which was involved in BC progression. However, its possible role in the progression of BC remains unclear. In this study, we found the high expression of SLP-2 in BC tissues and cells. SLP-2 promoted the viability of BC cells. In addition, we found that SLP-2 stimulated the motility of BC cells in vitro. Mechanically, our results revealed that SLP-2 could mediate FOXO3a expression and ERK signaling pathway, thereby contributing to the viability and motility of BC cells. Therefore, SLP-2 has the potential to serve as a promising target for BC treatment.

Non-Hodgkin's Lymphoma-Associated Pleural Effusion Misdiagnosed as Tubercular Pleural Effusion
Authors: Mallik Sonali , Datta Ananda , Kaur Amanpreet , Samal Swagatika
Published: July 2023

Adenosine deaminase (ADA) in the pleural fluid has high sensitivity and specificity for diagnosing tubercular pleuritis. ADA level of more than 40 IU/L in a lymphocytic and exudative effusion is suggestive of tubercular etiology in clinical practice. Antitubercular chemotherapy is often instituted without further histopathological or microbiological confirmation, especially in tuberculosis (TB)-endemic countries. Lymphoma is another important cause of elevated ADA levels in pleural fluid. Hence, in the absence of tissue diagnosis, lymphoma is often wrongly labeled as TB based on fluid characteristics. Here, we present a case of non-Hodgkin lymphoma with right-side pleural effusion who was initially misdiagnosed to have TB based on pleural fluid analysis.

Published: July 2023

A 61-year-old male with no significant medical history presented with dyspnea on exertion for the past 3 months. Clinical examination findings and electrocardiogram showed sinus rhythm and left ventricular hypertrophy. The chest X-ray and basic laboratory tests were within the normal limits. A transthoracic echocardiogram was performed which showed left ventricular wall thickening involving the anterior wall, lateral wall, septum, and inferior wall in the basal, mid, and apical segments. The left ventricular apex showed disproportionately increased thickness. There was no left ventricular outflow tract (LVOT) turbulence or obstruction. Left ventricular angiogram showed prominent trabeculations with deep intertrabecular recesses. LVOT obstruction was ruled out. The patient then underwent cardiac magnetic resonance imaging, which showed features suggestive of left ventricular noncompaction.
Longitudinal Strain and Sudden Cardiac Death
Authors: Vijayaraghavan Govindan
Published: July 2023

Several cardiac conditions are associated with the risk of ventricular arrhythmias (VAs) and sudden cardiac death (SCD). Identification of the individuals at increased risk of these events is essential to facilitate the appropriate measures to prevent SCD. Several clinical, electrocardiographic, and imaging markers have been used for this purpose with varying accuracy. Recently, longitudinal myocardial strain assessed using speckle-tracking echocardiography has been shown to have incremental value in the prediction of SCD risk. Strain imaging allows quantification of the abnormalities in the magnitude and timing of the segmental myocardial contraction, which is a surrogate for underlying myocardial fibrosis and myofiber disarray. Reduced segmental strain and temporal heterogeneity indicate electromechanical dispersion, which is the primary substrate for VAs and SCD. This review summarizes current evidence regarding the utility of longitudinal strain for the prediction of SCD risk.

Authors: Ayas Selahattin , Issi Elif Simin
Published: July 2023

Purpose:

This study aims to investigate the ulnar-median mixed nerve latency difference (U-MLD) recorded from the medial aspect of the arm both in patients with ulnar neuropathy at the elbow (UNE) and in healthy individuals and thus to assist in the diagnosis of UNE.

Materials and Methods:

Twenty-nine patients meeting electrophysiological criteria defined by the American Association of Neuromuscular and Electrodiagnostic Medicine for diagnosis of UNE, and 50 healthy individuals were included in the study retrospectively. All participants' data were evaluated, such as median/ulnar motor and sensory response, U-MLD and the percentage of ulnar mixed nerve response amplitude difference between sides.

Results:

The U-MLD was significantly higher in patients with UNE than in the control group (1.78 ± 0.64 ms vs. 0.6 ± 0.22 ms, P = 0.000). The percentage of the ulnar mixed nerve response amplitude loss was significantly higher in the patient group compared to the control group (43.9% ± 30.3% vs. 21.4% ± 12.2%, P = 0.018). The U-MLD was significantly higher in the patients with amplitude loss ≥50%, and the ulnar mixed nerve response amplitude loss was ≥50% in all five patients with the ulnar sensory nerve action potential pathology.

Conclusions:

U-MLD is higher in patients with UNE; it can provide additional data in mild cases regarding the diagnosis of UNE, especially. Furthermore, the criterion that the ulnar mixed nerve response amplitude difference between the sides ≥50% suggests that it can be used to evaluate the severity of UNE.

Objective:

The objective of the study was to determine the significance weights of the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) item scores for better evaluation and classification of amyotrophic lateral sclerosis (ALS) status.

Methods:

We used an analytical hierarchy process (AHP) to determine the weights of the ALSFRS-R item scores based on the opinions of two neurologists. We analyzed data of 51 patients with ALS to group them into four ALS severity classes based on their (i) total ALSFRS-R score and (ii) total weighted ALSFRS-R scores using the proposed weight values. We analyzed the performance differences between the two classification approaches based on the outcomes of these 51 patients. We also used twenty additional patients' data to analyze the accuracies of the total and weighted ALSFRS-R score approaches compared with physicians' actual assessments.

Results:

The AHP analysis assigned the highest weights to the ALSFRS-R items for respiratory insufficiency, orthopnea, and bed rotation/covering. ALS status classification based on the total and weighted ALSFRS-R scores differed for about 27.5% (confidence interval [CI]: 15.2%–39.8%) of the 51 patients. The classification based on the total weighted ALSFRS-R complied with the actual assessments in 85% (CI: 69.4%–100%) of the patients in the comparison sample; the compliance rate was 60% (CI: 38.5%–81.5%) for the total ALSFRS-R-based classification.

Conclusions:

Assigning weights to the 12 ALSFRS-R criteria/questions may improve ALSFRS-R's ability to represent ALS severity. This finding requires further investigation.

Published: July 2023

Veech groups are discrete subgroups of

\mathrm{SL}(2,\mathbb{R})

which play an important role in the theory of translation surfaces. For a special class of translation surfaces called origamis or square-tiled surfaces, their Veech groups are subgroups of finite index of

\mathrm{SL}(2,\mathbb{Z})

. We show that each stratum of the space of translation surfaces contains infinitely many origamis whose Veech group is a totally non-congruence group, i.e., it surjects to

\mathrm{SL} (2,\mathbb{Z}/n\mathbb{Z})

for any

n

Traveling waves and free boundaries arising in tumor angiogenesis
Authors: Fasano Antonio , Sinisgalli Carmela
Published: July 2023

In a paper appeared in 2021, a mathematical model was developed for tumor invasion with vessel cooption, including a fine analysis of angiogenesis driven by chemotaxis. Numerical solutions in spherical symmetry revealed that a traveling wave sets in. Results were in agreement with experimental data. In the present paper, we introduce some nontrivial changes in the model and we further analyze the structure of the solutions as well as their dependence on some critical biological parameters, emphasizing for instance which are the most active zones where angiogenesis takes place. Moreover, we propose an alternative model characterized by the presence of a free boundary (playing the role of the invasion front), showing that the new formulation (which is advantageous from the computational point of view) matches the results of the previous model for some biologically significant range of the parameters.
Transient Response of Turbocharged Compression Ignition Engine under
Different Load Conditions
Authors: Saad Syed Mohammad , Rummana Asiya
Published: July 2023

In urban roads the engine speed and the load vary suddenly and frequently,
resulting in increased exhaust emissions. In such operations, the effect of air
injection technique to access the transient response of the engine is of great
interest. The effectiveness of air injection technique in improving the
transient response under speed transient is investigated in detail [1]; however, it is not evaluated for the
load transients. Load step demand of the engine is another important event that
limits the transient response of the turbocharger. In the present study,
response of a heavy-duty turbocharged diesel engine is investigated for
different load conditions. Three cases of load transients are considered:
constant load, load magnitude variation, and load scheduling. Air injection
technique is simulated and after optimization of injection pressure based on
orifice diameter, its effect on the transient response is presented. The results
reveal that air injection into the intake manifold is an effective technique to
improve the turbo lag of a heavy-duty turbocharged diesel engine under the
transient conditions of load.
Evaluation of leukapheresis and leukapheresis with additional cytoreduction in acute leukemia with hyperleukocytosis
Authors: ALP KIRKIZLAR Tuğcan , DEMİR Ahmet Muzaffer
Published: July 2023

Background Hyperleukocytosis is a high-mortality emergency that must be diagnosed and treated promptly. The treatment options are low-dose cytosine arabinoside, hydroxyurea, steroids and leukapheresis. The risks and benefits of leukapheresis and leukapheresis with cytoreductive drugs in hyperleukocytosis are unclear. Therefore, we aimed to evaluate the efficacy of leukapheresis and the effect of adding cytoreductive drugs to leukapheresis in reducing leukocyte count and mortality in our patients.

Material and Methods Thirty-four adult patients with acute leukaemia who underwent leukapheresis were included in this retrospective study.

Results The median age was 66.5 years old, and 88.2% of the patients were acute myeloid leukaemia. The total number of leukapheresis was 69 cycles, and the median number of the procedure was 2. The most common symptoms were associated with the pulmonary system (67.6%). The median follow-up was 17.5 days. The mean reduction of leukocyte count was 69,112/mm3, and the efficacy of leukapheresis was 40.9%. The decrease in leukocyte and platelet counts was statistically significant when compared before and after leukapheresis. The mortality rate was 76.5% during hospitalization. While 24 patients received concomitant cytoreductive drugs with leukapheresis, ten did not. There was no statistically significant difference between these groups regarding reducing leukocyte count, efficiency of leukapheresis and mortality (p values 0.857, 0.562 and 0.553).

Conclusions In our study, we showed the efficacy of leukapheresis in hyperleukocytosis but failed to show any difference in leukocyte reduction or mortality with additional cytoreductive drugs. Leukapheresis with concomitant cytoreduction does not abolish or increase mortality.

Authors: Shaheed Khan  , Freeda Maria Swarna M  , R. Kannan
Published: July 2023

India was one of the earliest to have an Airline of its own when the Tata Group started an Airline in 1932. Post-Independence, Tata Airline which was rechristened as Air India was taken over by the Government in 1953. Then it was the tumultuous growth, development, and unfortunate fall of Air India/Indian Airlines. By 1991 the 1953 Law of Airlines (Air Corporation Act) was repealed and Private Airlines came into the picture. After which Indian skies underwent a phenomenal change. The research paper will focus on the way private sector has provided for Leadership on the Airline Segment through ‘business combinations’ that have helped ensure a versatile business segment. With coming back of the Tata group into the Airline business with Vistara and Air Asia India and the final take-over of Air India on 27th January 2022, Airlines was seeing a new Leadership emerge. Coming on page of Akasa Airline too has brought about a phenomenal business opportunity and a fillip for tourism and hospitality.
MODERNISMO EUROPEO E CULTURA ITALIANA IN CONSERVATORIO DI SANTA TERESA DI ROMANO BILENCHI
Authors:   Università “LUMSA”, Palermo, Italy, Barracco Giovanni
Published: July 2023

The essay intends to highlight how Romano Bilenchi’s novel represents one of the most interesting outcomes of the Italian culture of the novel in the early twentieth century in the broader framework of European Modernism. In Conservatorio di Santa Teresa, that fracture between life and experience, that crisis of the narration of experience and its representation as the mainstay of the early twentieth-century European narrative, is fully represented. The crumbling of certainties, in an atmosphere dominated by an empty allegory and by a condi- tion – that of the protagonist – of continuous tension, suspended between a desperate search for harmony now lost, in a reality that is now definitively dissonant, and the painful acknowl- edgment of the truth of men and nature, bring the novel closer to both Kafka’s metaphysical progress and Benjamin’s reflections on the relationship between memory and experience, by virtue of a narrative weaving supported by the lever of creative memory. A fully European novel, which dialogues fruitfully with the most advanced Trieste literary experiences (in the ever-living relationship between Florence and Trieste) and which is a prelude to Italian nov- els with similar themes and style (Agostino, Il ragazzo morto e le comete, L’isola di Arturo), Conservatorio di Santa Teresa is also a novel in which Bilenchi works a synthesis between the Italian tradition of the novel – which has some of its essential references in Tozzi and Manzoni – and the suggestions and expressive novelties and European themes of the twentieth cen- tury, through a controlled writing and a denotative style whose ultimate goal is to reveal the authentic substance of the characters, grasp their most underground movements, grasp their essence, by means of the tapering of any psychologism and a terseness of the prose that aims to rediscover that lost unity between word and thing from whose fracture modernity is born.
