Free space optical communication in Indian cities; channel characteristics and link performance
Authors: Rajput Sandeep , Acharya Yashwant 
Published: August 2023

Abstract
Free Space Optical (FSO) communication systems, offering high-speed and high-bandwidth transmission, have emerged as a possible substitute for conventional wired and wireless communication systems. However, FSO links are susceptible to atmospheric deficiencies including attenuation, scintillation, and turbulence, which may severely impact the performance of the communication link. In this research paper, we propose and analyze the performance of a 25 Gbps dual-polarization quadrature phase shift keying (DP-QPSK) coherent optical orthogonal frequency division multiplexing (CO-OFDM)-based FSO communication link with spatial diversity technique under various climatic conditions in four different geographical locations of India, i.e., Delhi, Ahmedabad, Kolkata, and Chennai in the year 2021. The proposed FSO communication system is evaluated through performance analysis and parametric evaluation under various weather conditions such as clear sky, fog, haze, rain, cloud, and thermal gradient. Key performance metrics such as bit error rate (BER), Q-factor, signal-to-noise ratio (SNR), received power, communication range, and reliability are analyzed based on the simulation results. The proposed FSO communication system provides high data rates, improved power efficiency, better resilience to atmospheric impairments, reliable communication links under different weather conditions, and a practical solution for high-speed and high-bandwidth communication in various applications.

Abstract

Context
Medical professionals commonly fail to follow best practice guidelines. Drift, or a return to previous tendencies, is abundant in healthcare even when guidelines are followed initially. This “drift” was found internally at Temple University Hospital with preoperative electrocardiograms (ECGs). Best-practice guidelines were instituted and followed as a first step, but sustaining performance improvement was the ultimate goal.

Objectives
The objectives are to improve and maintain adherence to published guidelines for preoperative ECG testing at Temple University Hospital in a physician-led, nurse practitioner (NP)–staffed preadmission testing (PAT) clinic.

Methods
To start this quality improvement (QI) project, a retrospective chart review was completed to determine the number of ECGs performed in PAT at Temple University Hospital in 2017. New guidelines for ordering preoperative ECGs were then implemented, and Plan-Do-Study-Act (PDSA) cycles were performed over 3 years. A repeat retrospective chart review was completed and looked at ECGs ordered from 2018 through 2020. The number of ECGs completed in PAT before and after implementation of the new guidelines was then compared. In addition, the complexity of our surgical patients was estimated by looking at the yearly average American Society of Anesthesiology Physical Health Status (American Society of Anesthesiology [ASA] status) values assigned. Finally, the cost of performing each ECG was calculated, and the cost savings to the hospital over 4 years was determined.

Results
The baseline ECG rate for PAT in 2017, 2018, 2019, and 2020 at Temple University Hospital was 54.0 , 20.7, 22.3, and 21.9 %, respectively, which was a statistically significant decrease in ECG performance rate in the years after implementation of the PDSA project. The ASA status average remained constant, demonstrating that while patients’ medical diagnoses remained on average the same, reinforced training had been effective in preventing a return to previous liberal ordering tendencies. Over the course of 4 years, the reduction in unnecessary ECGs led to an estimated direct cost savings of $213,000.

Conclusions
Self-adoption of best-practice guidelines among clinicians is often poor; however, the barriers to adoption can be overcome with education and individual feedback. Sustaining performance improvement gains is challenging, but possible, as shown by example in one urban, academic teaching hospital’s physician-led, NP–staffed outpatient clinic.
Specialization and finiteness (a)symmetry in imperative negation: with a comparison to standard negation
Authors: Van Olmen Daniël 
Published: August 2023

Abstract
This article focuses primarily on the claim in previous research that finiteness asymmetry occurs less often in imperative negation, due to its illocutionary dynamicity, than in standard negation, due to its stativity. Its secondary aim is to identify the languages suitable to test this hypothesis, with specialized imperatives as well as negative imperatives. The findings of this identification process in a balanced 200-language sample confirm the imperative and its negative counterpart as near-universal sentence types while simultaneously providing evidence for specialization asymmetry and thus for a certain mutual independence between the two. The results about finiteness asymmetry challenge the earlier claim: not only is finiteness asymmetry equally frequent in the two domains of negation; an explicit expression of illocutionary dynamicity can even give rise to it in imperative negation. In general, imperative negation’s finiteness asymmetry is found to be relatively unrelated to standard negation’s and not to be attributable to one single principle. The article shows that a variety of processes, such as grammaticalization and insubordination, are at work. They are argued to be motivated by the diachronic instability of negative imperatives, itself likely due to competing factors like politeness and negative reinforcement.

Published: August 2023

Abstract
Light-Emitting Diodes (LEDs) exhibit a typical Lambertian emission, raising the need for secondary optics to tailor their emission depending on specific applications. Here, we introduce plasmonic metasurfaces to InGaN green emitting quantum wells for LEDs to control their far-field emission directionality and enhance the collection efficiency. The proposed mechanism is based on surface lattice resonances (SLRs) and relies on the near-field coupling between the InGaN multiple quantum wells (MQWs) and periodic arrays of aluminum (Al) nanodisks. Fourier microscopy measurements reveal that the angular photoluminescence emission pattern depends on the lattice constant of the metasurfaces. We demonstrate that integrating Al metasurfaces in LED wafers can enhance the collected outcoupled light intensity by a factor of 5 compared to the same sample without metasurfaces. We have also performed numerical calculations of the far-field emission based on the reciprocity principle and obtained a very good agreement with the experimental data. The proposed approach controls the emission directionality without the need for secondary optics and it does not require post-etching of the GaN, which makes it a potential candidate to control and enhance the generated light from micro-LEDs.

Published: August 2023

Abstract
Poly(vinylidene fluoride) (PVDF) and its copolymers are promising candidates for energy-harvesting devices because of their flexibility, environmental friendliness, lightweight, and high halogen and acid resistance. However, the relatively low piezoelectricity limits their applications. The piezoelectricity of PVDF and its copolymers highly depends on the polar β-phase, while the non-polar α-phase is the most common one. As a result, the β-phase formation and α- to β-phase transformation have attracted much attention in recent years. Stretching is a widely used method to induce the α- to β-phase transformation for the improvement of piezoelectricity. In this work, the influences of the parameters during stretching on phase evolution and piezoelectricity are discussed and summarized. Besides, nontraditional stretching methods are also introduced and discussed. This work will provide important information for preparing high-performance piezoelectric polymer films.
Prior Knowledge Uses Prestimulus Alpha Band Oscillations and Persistent Poststimulus Neural Templates for Conscious Perception

Published: August 2023

Prior knowledge has a profound impact on the way we perceive the world. However, it remains unclear how the prior knowledge is maintained in our brains and thereby influences the subsequent conscious perception. The Dalmatian dog illusion is a perfect tool to study prior knowledge, where the picture is initially perceived as noise. Once the prior knowledge was introduced, a Dalmatian dog could be consciously seen, and the picture immediately became meaningful. Using pictures with hidden objects as standard stimuli and similar pictures without hidden objects as deviant stimuli, we investigated the neural representation of prior knowledge and its impact on conscious perception in an oddball paradigm using electroencephalogram (EEG) in both male and female human subjects. We found that the neural patterns between the prestimulus alpha band oscillations and poststimulus EEG activity were significantly more similar for the standard stimuli than for the deviant stimuli after prior knowledge was provided. Furthermore, decoding analysis revealed that persistent neural templates were evoked after the introduction of prior knowledge, similar to that evoked in the early stages of visual processing. In conclusion, the current study suggests that prior knowledge uses alpha band oscillations in a multivariate manner in the prestimulus period and induces specific persistent neural templates in the poststimulus period, enabling the conscious perception of the hidden objects.SIGNIFICANCE STATEMENTThe visual world we live in is not always optimal. In dark or noisy environments, prior knowledge can help us interpret imperfect sensory signals and enable us to consciously perceive hidden objects. However, we still know very little about how prior knowledge works at the neural level. Using the Dalmatian dog illusion and multivariate methods, we found that prior knowledge uses prestimulus alpha band oscillations to carry information about the hidden object and exerts a persistent influence in the poststimulus period by inducing specific neural templates. Our findings provide a window into the neural underpinnings of prior knowledge and offer new insights into the role of alpha band oscillations and neural templates associated with conscious perception.

AbstractThe H3K4 methyltransferase SETD1A plays a crucial role in leukemia cell survival through its noncatalytic FLOS domain‐mediated recruitment of cyclin K and regulation of DNA damage response genes. In this study, we identify a functional nuclear localization signal in and interaction partners of the FLOS domain. Our screen for FLOS domain‐binding partners reveals that the SETD1A FLOS domain binds mitosis‐associated proteins BuGZ/BUB3. Inhibition of both cyclin K and BuGZ/BUB3‐binding motifs in SETD1A shows synergistic antileukemic effects. BuGZ/BUB3 localize to SETD1A‐bound promoter‐TSS regions and SETD1A‐negative H3K4me1‐positive enhancer regions adjacent to SETD1A target genes. The GLEBS motif and intrinsically disordered region of BuGZ are required for both SETD1A‐binding and leukemia cell proliferation. Cell‐cycle‐specific SETD1A restoration assays indicate that SETD1A expression at the G1/S phase of the cell cycle promotes both the expression of DNA damage response genes and cell cycle progression in leukemia cells.

Published: August 2023

O presente estudo tem como objetivo analisar os desvios relativamente ao emprego do Pretérito Perfeito Simples (PPS) e do Pretérito Imperfeito (PI) que ocorreram durante uma prova realizada por aprendentes universitários polacos e búlgaros de PLE, procurando explicar a sua origem. A análise, quantitativa e qualitativa, tem como base o contraste entre o português e as línguas eslavas quanto à marcação do tempo e do aspeto. A ocorrência de desvios no uso do PPS e do PI indica que a escolha do PI ou PPS suscita dúvidas nos estudantes estrangeiros de PLE em contexto não imersivo, mesmo que as suas línguas maternas ofereçam condições para uma transferência positiva. Dada a importância do PI e do PPS na construção de enunciados coesos em PLE, os resultados hão de estimular a escolha de métodos inovativos para o reforço da aprendizagem aos diferentes níveis de proficiência dos estudantes.

Authors: Lubis Yusuf Hanafi , Susilawati Susilawati 
Published: August 2023

Background: Adolescents tend to want to try things they have never experienced, and the main contributing factor is curiosity and imitating what adults do, including sexuality.
Aims: This study aimed to analyze the transmission prevention program of HIV and Syphilis for adolescents in North Sumatra.
Methods: This study used an analytic survey approach with a cross-sectional design by taking 729 people as a sample, selected using quota sampling, from the total adolescent population (19.4% of the population of North Sumatra). Questionnaires produced using an online platform and adapted from The Prospero Network. The results were then transferred into a statistics-based application for descriptive data analysis, bivariate, and multi-level tests.
Results: The study showed that >50% of the respondents took a quick, free laboratory test for HIV and syphilis and a reactive confirmation test through a health facility in both cases. Moreover, the results of multi-level statistical tests show models 1 and 2, namely the availability of syphilis screening referrals, have a 1-17 times higher risk of implementing HIV and syphilis programs in adolescents.
Conclusion: Everything is interrelated with the implementation of HIV and Syphilis transmission prevention programs in adolescents. However, there is still a significant chance that it will not work. Therefore, the government and the community must work together to implement this program properly and consistently.
