Identification of solar periodicities in southern African baobab δ13C record
Authors: Kotzé Pieter B. 
Published: July 2020

Spectral analysis using wavelet, Lomb–Scargle and maximum entropy techniques of the proxy rainfall record of northeastern South Africa based on annual carbon isotope (δ13C) data obtained from baobab trees for the period 1600 AD – 2000 AD show clear evidence of the presence of characteristic solar periodicities. Solar periodicities that were identified above the 95% confidence level include the ~11-year Schwabe cycle, the ~22-year Hale cycle as well as the 80–110-year Gleissberg cycle. A Morlet wavelet analysis of the δ13C data between 1600 AD and 1700 AD shows the effect of the Maunder sunspot minimum on both the Schwabe and Hale cycles during this time.
Significance:

A spectral analysis of δ13C baobab tree ring data for southern Africa between 1600 AD and 2000 AD is presented. The results show – for the first time – that the δ13C time series contains the 11-year Schwabe, 22-year Hale as well as the 80–110-year Gleissberg solar periodicities. In addition, the influence of the Maunder sunspot minimum between ~1650 AD and 1715 AD could also be clearly identified in the δ13C data for the first time. These findings are of significant importance to investigations of solar influences on climate variability.
A few hours in the Seychelles with Alex du Toit in 1938
Authors: Master Sharad 
Published: July 2020

Alexander Logie du Toit (1878–1948) was South Africa’s most famous geologist during his lifetime, having authored five books which brought him world renown. In December 1937 to January 1938, accompanied by his wife Evelyn, he visited India in order to attend the Jubilee Indian Science Congress in Calcutta and to do field work in coal and diamond mines. On the return journey to Africa by ship, they stopped for a few hours in Port Victoria on Mahé Island in the Seychelles archipelago. They also passed by Silhouette Island. Du Toit recorded his activities in a diary, and his geological observations in a notebook, where he also drew a sketch of Mahé, and recorded steep structures on the east coast of Silhouette. Although he had not visited the Seychelles before, his deep understanding of the problems of Seychelles geology resulted from his comprehensive research on Indian Ocean geology for his 1937 book Our Wandering Continents. He made remarkably accurate observations on the geomorphology and structure, some of which were only confirmed decades later when the Seychelles were mapped in the 1960s to 1990s. His bold and prescient ideas on the breakup of the Gondwana continent, and on the formation of the Indian Ocean, have been amply confirmed by modern studies, especially by those of Lewis D. Ashwal and his collaborators.
Significance:

South African geologist Alexander Logie du Toit’s impressions of the Seychelles in 1938 are recorded for the first time, based on entries in his diaries. His observations of structures on Mahé and Silhouette Islands were prescient. His deep understanding of Seychelles geology was the result of his research for his 1937 book Our Wandering Continents. His bold conjecture that the Mascerene Ridge, made of continental crust, was the nucleus of Mauritius, was finally proved in 2017.
Homofobia no futebol masculino: revisão narrativa de literatura
Authors: De Souza Daniel Cerdeira 
Published: July 2020

INTRODUÇÃO: O Brasil é conhecido como o país do futebol, que é um campo de encontro de masculinidades regidas pela norma heterossexual, onde dissidentes desse aspecto podem ser marginalizados nesse espaço. OBJETIVO: Dessa forma, este estudo objetivou discutir a homofobia no contexto do futebol. MÉTODOS: Metodologicamente, esta é uma revisão narrativa da literatura, onde foram analisados 6 artigos, 5 em português e 1 em inglês, publicados entre 2012-2018 indexados nas bases de dados Scielo, PEPSIC, BVS e Capes. Os dados coletados foram analisados a partir da elaboração de um protocolo de revisão e posteriormente a partir da técnica Análise de Conteúdo. RESULTADOS: Os resultados foram compilados em cinco categorias: 1) Futebol como contexto de performatividade de masculinidade; 2) Homossexuais no futebol; 3) A homossociabilidade no futebol; 4) Os estádios, a torcida, a linguagem e a mídia; 5) Torcidas queers e inclusão, que discutiram que o futebol é um contexto de performatividade da masculinidade hegemônica do projeto heterossexual, onde homossexuais tem sua participação limitada e/ou banida. CONSIDERAÇÕES FINAIS: Caso desejem participar do esporte, homossexuais precisam se adequar a norma heterossexual, geralmente permanecendo no armário. É permitida a homossociabilidade no futebol como forma de amor ao time e a linguagem é usada como meio onde a violência homofóbica é expressada, mas admite-se que mudanças nesse cenário estão ocorrendo, ainda que a passos lentos, possibilitando a proposta de masculinidades inclusivas. Conclui-se que o futebol representa bem mais do que um esporte, mas um jogo político e um dispositivo da sexualidade, que regula as relações de gênero entre homens.
A STUDY ON INDIA’S BILATERAL TRADE WITH JAPAN
Authors: Raghuramapatruni Radha , D Asha Latha. 
Published: July 2020

Purpose of the study: India and Japan share strong cultural and economic ties. The economic relationship between the two Asian giants strengthened with the signing of the CECA agreement during the year 2011. The current research would focus on assessing the bilateral trade relations between both the countries and attempts to identify the commodity trade potential to enhance the future trade between them.
Methodology: The study is based on secondary sources of data collected through the United Nations Conference for Trade and Development, WTO, IMF, RBI, and the Japanese Trade Databases. The annual data for the period 2005 to the year 2016 has been used to analyse the Intensity Indices and the Gravity Coefficient values between India and Japan. Similarly, the annual data from the year 2008 to 2015 is used to calculate the RCA and RID index values and finally, the average RCA and RID (2008-2016) are used for analysis to identify the commodity trade potential between both the countries.
Main Findings: The study concludes that the trade share of Japan in India’s overall trade has been falling significantly over the years which could be seen through the declining Export Intensity and Import Intensity Indices of India with Japan. However, the overall analysis presents that 28 commodities were feasible for trade between India and Japan from the 56 commodities computed for the study which exhibits a strong potential for enhancing future bilateral trade relations between both the countries.
Applications of this study: India had made a strategic move with its Look East Policy during the year 1991 to accelerate its trade relations with the East Asian countries and later with its success the same was transformed into Act East Policy during the year 2014. The current study would prove to be useful in shaping the policy changes in this direction.
Novelty/Originality of this study: The study focuses on the bilateral trade relations between the two important Asian giants, India, and Japan during the post comprehensive economic cooperation agreement between the two. Further, the study identifies the areas of commodity trade potential which paves the direction for new trade between the countries to tap the untapped trade potential.

Published: July 2020

Background & Objectives: Local Anesthesia (LA) is getting popularity in comparison to general anesthesia (GA) in underdeveloped and developing countries in many otolaryngological operations. The rationale for LA is the lack of trained anesthesia staff, lack of adequate anesthesia machines and monitoring equipment. LA is safe; and ability to perform more cases in a shorter period of time. This study aimed to find out patients compliance in the operative procedures under LA without sedation.
Methods: 7905 patents underwent tympanoplsty under LA without sedation from 1999 to 2019 in the different hospital of Bangladesh. Preoperative thorough counselling with psychological motivation, advantages of LA, intraoperative surgeon patient conversation and watching surgical steps on monitor, tests of facial nerve function were explained to the patient. LA with different Adrenaline concentrations (1: 1000 to 1: 200,000) was used either by injection or topically. Patients’ satisfaction, vertigo, drowsiness, hangover, orientation and other parameters ware recorded.
Results: Amongst 7905 patients; male 56.2% and 43.8% was female. Maximum numbers (26.3) were found between 26 year to 35 year of age. Patients’ intraoperative compliance showed excellent without sedation. Operative time was short with a bloodless field. The overall safety was good and needed shortest hospital stay (Hour/day); and of course very less expensive.
Conclusion: Patient’s safety is the primary objective considered in all patients. The advantages recorded as day/hour care hospital stay, patients comfort, less bleeding, ability to assess patient’s hearing during surgery and cost effectiveness
Subacute Minimally Invasive Decompression of L5 and S1 Nerve Roots for Neurologic Deficit After Fixation of Unstable Pelvic Fracture
Authors: Warren Shay , Gardner Michael , Alamin Todd 
Published: July 2020

Case:
A 73-year-old man experienced immediate neurological decline after percutaneous transsacral screw fixation for a pelvic ring injury sustained after a 25-foot fall. Workup revealed well-positioned screws and compression of the right L5 and S1 nerve roots at the fracture site. Symptoms improved after direct decompression without screw revision.

Conclusion:
The courses of the L5 and S1 nerve roots place them at risk of compression within the fracture during transsacral screw fixation. In highly comminuted fractures, avoidance of compression screws or use of intraoperative CT might prevent this complication. Direct nerve root decompression alone can be a successful treatment.

Published: July 2020

Abstract
Purpose. There are no currently approved non-invasive methods for detecting tumor treatment responses within the first few days of treatment. The monoclonal antibody, DAB4, or its chimeric derivative, chDAB4 (APOMAB®), targets the Lupus-associated or Sjögren Syndrome-B antigen (La/SSB). La/SSB is over-expressed in malignancy and is selectively targeted by chDAB4 in cancer cells that have died after DNA-damaging treatment. Therefore, chDAB4 could be used to distinguish between chemotherapy responsive and non-responsive patients. In this study, we performed preclinical validation studies using whole-body Positron-Emission Tomography (PET) to examine tumor and normal tissue uptake of 89Zr-labeled chDAB4 in lung or ovarian tumor-bearing mice, which were left untreated or given cisplatin chemotherapy.Methods. The binding of chDAB4 and its conjugates to dead cisplatin-treated human lung and ovarian cancer cells was assessed in vitro as well as its Fc-dependent effector functions. Mice bearing xenografts of H460 lung cancer or A2780 ovarian cancer cells were untreated or given cisplatin chemotherapy followed 24 hours later by 89Zr-labeled chDAB4. Post-cisplatin tumor responses were monitored using bioluminescence imaging and caliper measurements and 89Zr-labeled chDAB4 tumor uptake was measured using an Albira SI PET imager and PMOD analysis software. On completion of experiments, organs were dissected and biodistribution of 89Zr-labeled chDAB4 was measured using a Hidex gamma-counter.Results. The chDAB4 antibody bound only to dead A2780 and H460 cells, and its binding increased with cisplatin treatment in vitro. The chDAB4 antibody did not exhibit Fc-dependent effector functions. Chemotherapy significantly increased uptake of 89Zr-labeled chDAB4 in tumors but not in normal tissues for each tumor model. The greatest differences in average uptake of 89Zr-labeled chDAB4 in subcutaneous tumors were observed 3 days post-cisplatin chemotherapy compared to untreated mice, and before tumor shrinkage was evident.Conclusion. After administration of cisplatin chemotherapy, tumor xenograft uptake of 89Zr-labeled chDAB4 was detected in vivo by PET imaging. Given that the chDAB4 mAb lacked effector activity and that malignant rather than normal tissues were targeted after chemotherapy, these results support clinical development of chDAB4 as both a predictive marker of chemotherapy response and a theranostic imaging agent, which may guide subsequent delivery of chDAB4-directed antibody drug or radio-conjugate anticancer therapies.

Authors: Wang Renqiang , Li Qinrong , Miao Shengze , Miao Keyin , Deng Hua 
Published: July 2020

Purpose:
The purpose of this paper was to design an intelligent controller of ship motion
based on sliding mode control with a Radial Basis Function (RBF) neural network optimized by the
genetic algorithm and expansion observer. First, the improved genetic algorithm based on the distributed
genetic algorithm with adaptive fitness and adaptive mutation was used to automatically optimize
the RBF neural network. Then, with the compensation designed by the RBF neural network, antisaturation
control was realized. Additionally, the intelligent control algorithm was introduced by Sliding
Mode Control (SMC) with the stability theory. A comparative study of sliding mode control integrated
with the RBF neural network and proportional-integral-derivative control combined with the
fuzzy optimization model showed that the stabilization time of the intelligent control system was
43.75% faster and the average overshoot was reduced by 52% compared with the previous two attempts.
Background: It was known that the Proportional-Integral-Derivative (PID) control and self-adaptation
control cannot really solve the problems of frequent disturbance from external wind and waves, as well
as the problems with ship nonlinearity and input saturation. So, the previous ship motion controller
should be transformed by advanced intelligent technology, on the basis of referring to the latest relevant
patent design methods.

Objective:
An intelligent controller of ship motion was designed based on optimized Radial Basis Function
Neural Network (RBFNN) in the presence of non-linearity, uncertainty, and limited input.

Methods:
The previous ship motion controller was remodeled based on Sliding Mode Control (SMC)
with RBFNN optimized by improved genetic algorithm and expansion observer. The intelligent control
algorithm integrated with genetic neural network solved the problem of system model uncertainty, limited
control input, and external interference. Distributed genetic with adaptive fitness and adaptive mutation
method guaranteed the adequacy of search and the global optimal convergence results, which
enhanced the approximation ability of RBFNN. With the compensation designed by the optimized
RBFNN, it was realized anti-saturation control. The chattering caused by external disturbance in SMC
controller was reduced by the expansion observer.

Results:
A comparative study with RBFNN-SMC control and fuzzy-PID control, the stabilization time
of the intelligent control system was 43.75% faster, the average overshoot was reduced by 52%, compared
to the previous two attempts.

Conclusion:
The intelligent control algorithm succeed in dealing with the problems of nonlinearity,
uncertainty, input saturation, and external interference. The intelligent control algorithm can be applied
into research and development ship steering system, which would be created a new patent.
An Intelligent Mobile-Enabled System for Diagnosing Parkinson Disease: Development and Validation of a Speech Impairment Detection System
Authors: Zhang Liang , Qu Yue , Jin Bo , Jing Lu , Gao Zhan , Liang Zhanhua 
Published: July 2020

Background
Parkinson disease (PD) is one of the most common neurological diseases. At present, because the exact cause is still unclear, accurate diagnosis and progression monitoring remain challenging. In recent years, exploring the relationship between PD and speech impairment has attracted widespread attention in the academic world. Most of the studies successfully validated the effectiveness of some vocal features. Moreover, the noninvasive nature of speech signal–based testing has pioneered a new way for telediagnosis and telemonitoring. In particular, there is an increasing demand for artificial intelligence–powered tools in the digital health era.

Objective
This study aimed to build a real-time speech signal analysis tool for PD diagnosis and severity assessment. Further, the underlying system should be flexible enough to integrate any machine learning or deep learning algorithm.

Methods
At its core, the system we built consists of two parts: (1) speech signal processing: both traditional and novel speech signal processing technologies have been employed for feature engineering, which can automatically extract a few linear and nonlinear dysphonia features, and (2) application of machine learning algorithms: some classical regression and classification algorithms from the machine learning field have been tested; we then chose the most efficient algorithms and relevant features.

Results
Experimental results showed that our system had an outstanding ability to both diagnose and assess severity of PD. By using both linear and nonlinear dysphonia features, the accuracy reached 88.74% and recall reached 97.03% in the diagnosis task. Meanwhile, mean absolute error was 3.7699 in the assessment task. The system has already been deployed within a mobile app called No Pa.

Conclusions
This study performed diagnosis and severity assessment of PD from the perspective of speech order detection. The efficiency and effectiveness of the algorithms indirectly validated the practicality of the system. In particular, the system reflects the necessity of a publicly accessible PD diagnosis and assessment system that can perform telediagnosis and telemonitoring of PD. This system can also optimize doctors’ decision-making processes regarding treatments.
Implementing Psychological Interventions Through Nonspecialist Providers and Telemedicine in High-Income Countries: Qualitative Study from a Multistakeholder Perspective
Authors: Singla Daisy Radha , Lemberg-Pelly Sasha , Lawson Andrea , Zahedi Nika , Thomas-Jacques Tyla , Dennis Cindy-Lee 
Published: July 2020

Background
Task sharing has been used worldwide to improve access to mental health care, where nonspecialist providers—individuals with no formal training in mental health—have been trained to effectively treat perinatal depressive and anxiety symptoms. Little formative research has been conducted to examine relevant barriers and facilitators of nonspecialist providers and the use of telemedicine in treatment service delivery.

Objective
The primary objective of this study was to examine the main barriers and facilitators of nonspecialist provider–delivered psychological treatments for perinatal populations with common mental health disorders, such as depression and anxiety, from a multistakeholder perspective.

Methods
This study took place in Toronto, Canada. In total, 33 in-depth interviews were conducted with multiple stakeholder groups (women with lived experience and their significant others, as well as health and mental health professionals). Qualitative data were quantified to estimate commonly endorsed themes within and across stakeholder groups.

Results
Psychological treatments delivered by nonspecialist providers were considered acceptable by the vast majority of participants (30/33, 90%). Across all stakeholder groups, nurses (20/33, 61%) and midwives (14/33, 42%) were the most commonly endorsed cadre of nonspecialist providers. The majority of stakeholders (32/33, 97%) were amenable to nonspecialist providers delivering psychological treatment via telemedicine (27/33, 82%), although concerns were raised about the ability to establish a therapeutic alliance via telemedicine (16/33, 48%). Empathy was the most desired characteristic of a nonspecialist provider (61%). Patient and patient advocate stakeholders were more likely to emphasize stigma as an important barrier to accessing psychological treatments (7/12, 58%), compared to clinicians (2/9, 22%) and spouses (1/5, 20%). Clinician stakeholders were more likely to emphasize the importance of ensuring nonspecialist providers were trained to deliver psychological treatments (3/9, 33%), compared to other stakeholder groups.

Conclusions
These results can inform the design, implementation, and integration of nonspecialist-delivered interventions via telemedicine for women with perinatal depressive and anxiety symptoms in high-income country contexts.
