Authors: Mukhseni Muhammad Redzki Nurfadillah , Widyatama Rendra
Published: November 2023

In March 2023, Elon Musk changed Twitter's logo to a white X symbol on a black background, replacing the old Twitter logo, which had been a blue bird image used for 17 years. This change sparked a debate, especially since people had become familiar with Twitter's old logo and had formed a connection with the social media platform through it. In marketing communication, the brand name reflects a company's identity and creates its own perception among the audience. Changes to the brand will also alter people's perceptions of the company. This research aims to uncover the audience's perception of the old and new Twitter brand images. The research uses a quantitative approach, where the researcher collected data through an online questionnaire involving 300 active Twitter users as respondents. Data analysis used the Paired t-Test statistical method to analyze differences in perception. The research results show that there is a significant difference in perception between the old and new versions of the Twitter brand name. This is evidenced by a p-value of 0.000.

Pathological diagnosis and immunohistochemical analysis of minute pulmonary meningothelial-like nodules: A case report
Authors: Ruan Xin , Wu Liu-Sheng , Fan Zheng-Yang , Liu Qi , Yan Jun , Li Xiao-Qiang
Published: November 2023

BACKGROUND

Minute Pulmonary Meningothelial-like Nodules (MPMNs) are rare benign pulmonary nodules, which are more common in elderly women and have a higher detection rate in lung tissues of patients with lung malignant diseases. Its origin is not yet clear. At present, there are few reports on the diagnostic methods such as imaging and pathological manifestations of MPMNs. This article reports a 70-year-old female patient with pulmonary adenocarcinoma combined with MPMNs and reviews of the relevant literature.

CASE SUMMARY

A 70-year-old women was admitted to our institution with feeling sour in her back and occasional cough for more than 2 mo. Computerized electronic scanning scan and 3D reconstruction images in our institution showed there were multiple ground-glass nodules in both of her two lungs. The biggest one was in the apicoposterior segment of left upper lobe, about 2.5 mm × 9 mm in size. We performed thoracoscopic resection of the left upper lung apicoposterior segment of the patient, and the final pathological report was minimally invasive adenocarcinoma. Re-examination of high resolution computed tomography 21 mo after surgery showed multiple ground-glass nodules in both lungs, and a new ground-glass nodule was found in the superior segment of the right lower lobe. We took pathological biopsy of the right upper lung and right lower lung nodules for the patient under thoracoscopy. The histomorphology of the right lower lobe nodule showed multiple lesions in the lung tissue, and the small foci in the alveolar septum were distributed in mild form of the aggregation of short spindle cells. The immunohistochemistry showed that the lesion was epithelial membrane antigen (EMA) (+), somatostatin receptor 2a (SSTR2a) (+), S-100 (-), chromogranin A (-), Syn (-), cytokeratin (-) and HMB-45 (-). The final diagnosis was minimally invasive adenocarcinoma, accompanied by MPMNs. We recommend that patients continue to receive treatment after surgery and to do regular follow-up observations.

CONCLUSION

The imaging manifestations of MPMNs are atypical, histomorphology and immunohistochemistry can assist in its diagnosis. This article reviews the relevant literature of MPMNs immunohistochemistry and shows that MPMNs are positive for EMA, SSTR2a, and progesterone receptor.
Cost-utility analysis of robotic arm-assisted medial compartment knee arthroplasty
Authors: Clement Nick. D. , Fraser Ewen , Gilmour Alisdair , Doonan James , MacLean Angus , Jones Bryn G. , Blyth Mark J. G.
Published: November 2023

Aims

To perform an incremental cost-utility analysis and assess the impact of differential costs and case volume on the cost-effectiveness of robotic arm-assisted unicompartmental knee arthroplasty (rUKA) compared to manual (mUKA).

Methods

This was a five-year follow-up study of patients who were randomized to rUKA (n = 64) or mUKA (n = 65). Patients completed the EuroQol five-dimension questionnaire (EQ-5D) preoperatively, and at three months and one, two, and five years postoperatively, which was used to calculate quality-adjusted life years (QALYs) gained. Costs for the primary and additional surgery and healthcare costs were calculated.

Results

rUKA was associated with a relative 0.012 QALY gain at five years, which was associated with an incremental cost per QALY of £13,078 for a unit undertaking 400 cases per year. A cost per QALY of less than £20,000 was achieved when ≥ 300 cases were performed per year. However, on removal of the cost for a revision for presumed infection (mUKA group, n = 1) the cost per QALY was greater than £38,000, which was in part due to the increased intraoperative consumable costs associated with rUKA (£626 per patient). When the absolute cost difference (operative and revision costs) was less than £240, a cost per QALY of less than £20,000 was achieved. On removing the cost of the revision for infection, rUKA was cost-neutral when more than 900 cases per year were undertaken and when the consumable costs were zero.

Conclusion

rUKA was a cost-effective intervention with an incremental cost per QALY of £13,078 at five years, however when removing the revision for presumed infection, which was arguably a random event, this was no longer the case. The absolute cost difference had to be less than £240 to be cost-effective, which could be achieved by reducing the perioperative costs of rUKA or if there were increased revision costs associated with mUKA with longer follow-up.

Eugenic Ecologies of Herbicidal Warfare in the Vietnam War
Authors: Bui Keva X.
Published: November 2023

Abstract: This article examines scientific, environmentalist, and aesthetic responses to the deployment of herbicidal chemicals across agricultural capitalism domestically in the United States and military intervention in Southeast Asia. Herbicides are weed killers, and by analyzing the social construction of the "weed" as politically expendable life across racialized, capitalist, ableist, and militarized geographies, this article situates the history of herbicidal warfare within a discourse of eugenics. Eugenics, as a politically inflected science of preserving valued life at the expense of devalued life, provides an important optic for understanding how militarized necropolitics consign different forms of human and nonhuman life as disposable in the pursuit of Cold War securitization. Bringing together disability studies and environmental justice critique to think about these racial logics of herbicidal warfare, this article develops a framework of eugenic ecologies in order to consider the herbicide as a racializing technology that shapes the contours of human and plant life as intertwined targets of the imperial war machine.
Fast phase retrieval for broadband attosecond pulse characterization
Authors: Wang Jiacan , Xiao Fan , Wang Li , Tao Wenkai , Wang Xiaowei , Zhao Zengxiu
Published: November 2023

Efficient characterization method for broadband attosecond pulses has become more and more essential, since attosecond pulses with bandwidth spanning few-hundreds electron-volts have been generated. Here we propose a fast phase retrieval algorithm for broadband attosecond pulse characterization with an omega oscillation filtering technique. We introduce a new error function to improve the accuracy of the retrieved phases. More importantly, it can be solved by the steepest descent methods with iterative algorithm, which is much faster than genetic algorithm adopted previously. An experimental spectrogram for isolated attosecond pulses with photon energy covering 52–127 eV and a pulse width of 71 as was successfully retrieved with this method as demonstrated. The proposed technique will help provide real-time feedback on atto-chirp compensation for ultrashort isolated attosecond pulse generation.
Unveiling the electronic structure and optical properties of two-dimensional TMDCs: first-principles study
Authors: Gul Banat , Khan Muhammad Salman , Mohamed Abdelhay Salah , Wafa Guenez , Ahmad Hijaz
Published: November 2023

Transition metal dichalcogenide (TMDC) materials are considered extremely efficient materials with significant applications in photovoltaics and optoelectronics. Here, the electronic structure and optoelectronic features of new transition metal-containing dichalcogenides are studied using state-of-the-art density functional theoretical calculations. For the analysis of the electronic band structures, we employed a modified Becke-Johnson potential. According to the band structure analysis, Platinum-based dichalcogenides possess an indirect band profile, having the valence band maximum and the conduction band minimum situated at discrete symmetry regions. At the same time, the zirconium-based materials have a direct type band structure at the same Γ-point. We calculated cohesive energies and formation energies to assess the stability of these materials. The substantial optical parameters such as the two parts of the dielectric constant, absorption coefficients, energy loss functions, reflectivity spectra, refractive index, real optical conductivity spectra, spectra, and the extinction coefficients, are calculated. These findings provide insight into potential applications in optoelectronic devices. The calculated band gaps and refractive index revealed an inverse relationship. This research aims to make a significant contribution to the advancement of various and possibly gainful semiconducting technologies, as well as their practical applications.

In repositioning themselves, PSM have increasingly embraced some of the core characteristics of platforms by developing a central video-on-demand (VOD) service as portal to PSM services, investing in exclusive content and using data to create richer user experiences and gain insights into audience practices. However, this ‘platformization’ process comes with both challenges and opportunities to reach the public service remit. This article conducts an analysis of the on-demand portals of PSM, to uncover how platformization is reshaping the PSM core remit and values, and how these are transposed in online services and offerings. The research employs a comparative case study analysis of five VOD services of PSM in Western and Northern Europe: Belgium-Flanders (VRT.NU), Belgium-Wallonia (RTBF Auvio), Finland (Yle Areena), Ireland (RTÉ Player) and Norway (NRK TV). The results discuss three main categories: interfaces and features, strategies for catalogue and content curation, and tools for discoverability and prominence.

Background and Aim: Antibiotic resistance in Klebsiella pneumoniae, especially extended-spectrum beta-lactamase (ESBL) producers, has become a global public health problem. This study aimed to estimate the prevalence of multidrug resistance (MDR) and ESBL-producing K. pneumoniae in wastewater from dairy farms.

Materials and Methods: This study was conducted on dairy farms in East Java Province from June to October 2022. In total, 342 dairy farm wastewater samples were isolated on buffered peptone water media from six cities/regencies with the highest dairy cattle population in East Java. Samples were identified using MacConkey agar media, Gram-staining,eosin-methylene blue agar, and biochemical tests. In total, 14.32% (49/342) samples contained K. pneumoniae. Positive isolates were tested for antibiotic sensitivity. Klebsiella pneumoniae resistant to beta-lactam was confirmed using the double-disk synergy test to confirm the presence of ESBL-producing bacteria.

Results: The percentage of antibiotic resistance in K. pneumoniae was 98% resistance to ampicillin, 67.3% to cefotaxime, 46.9% to tetracycline, 49% to ciprofloxacin, 98% to streptomycin, 14.3% to sulfamethoxazole–trimethoprim, and 83.7% to chloramphenicol. The prevalence of MDR in K. pneumoniae was 12.57% (43/342), with the highest prevalence in the five classes of antibiotics at 41.86% (18/43), and the prevalence of ESBL-producing K. pneumoniae was 5.55% (19/342), with the highest prevalence in the districts of Blitar and Pasuruan at 26.31% (5/19).

Conclusion: Although the prevalence of ESBL-producing K. pneumoniae in wastewater samples from dairy farms was low, caution is recommended because they can be a reservoir for ESBL.

The processes of modifying the surface of multi-walled carbon nanotubes growing with polar substances – carboxyl, alcohol, hydroxyl, quaternary ammonium salt – have been studied. With the combination of an oxidizing mixture of hydrogen peroxide, nitric and sulfuric acids, a technology has been developed for the carboxylation of carbon nanotubes at 70 °C, which results in minimal formation of amorphous carbon and increases the content of carboxyl groups on a surface to 5.5 %. The reaction of carboxylated carbon nanotubes with triethanolamine has led to the tubes with the surface modified by a quaternary ammonium salt. Modification of carbon nanotubes by ethyl hydroxyl groups has been carried out with the participation of a free-radical initiator in an ethanol medium. It has been shown that the number of defects that occur during formation of chemical bonds in the process of functionalization, as well as their nature, are predominantly determined by the initial defects of nanotubes and do not depend on the processing of the nanocarbon material. A study of the thermal-oxidative stability of the original and modified carbon nanotubes has been carried out. The original nanotubes are the most stable, heated in air up to 520 °C. Thermal stability for the investigated modified nanotubes decreases in the series: multi-walled nanotubes with carboxyl groups on the surface, with alcohol hydroxyl groups modified by a quaternary ammonium salt, in which oxidation begins at 400 °C. Grafting alcohol hydroxyl groups on the surface of multiwalled carbon nanotubes is of considerable interest for the formation of a sorption material with a developed surface, capable of covalently binding metal ions due to hydroxyl groups, similar to complexing agents such as ethylene glycol or pyrocatechol. The surface modification of carbon nanomaterials with polar groups leads to good sorption properties for the heavy metal ions. The extraction of zinc and copper ions in the case of carboxylated nanotubes is up to 98 %.
