Vestiges of Reftâr in historical music notations
Authors: Değirmenci Zehra Tülin 
Published: April 2021

Reftâr is known as a woman composer who lived in the Ottoman Empire Harem in the 17th century. We see compositions attributed to her in musical archives under names such as Reftâr Kalfa, Tanburi Reftâr Kalfa, and Musahip. Today, the claim that Reftâr was the first woman composer in Turkish classical music is based on a Peşrev – Der Makâm -ı Saba ‘‘Sabâ -yı Reftâr’’usüleş Düyek - found in the Kantemiroğlu Edvârı.
In this study, Hamparsum Manuscripts, which were written using the Hamparsum musical notation developed at the beginning of the 19th century, were studied and it has been discovered that, in addition to Reftâr’s well known Saba Peşrev, there is also a Saba Saz Semâîsi attributed to her. Two Saz Semâîsi in the Saba makam, which were found in the Hamparsum Notebooks with archive numbers Y.205/3 and Y.211/9 at the Istanbul University Library of Rare Books were translated into modern Western notation and studied. Reftâr’s life as a musician and the music training of women in the Ottoman palace were studied based on written sources, in order to understand Reftâr’s place in the Turkish Classical Music tradition as a musician and a woman.
Writing about the traditional Turkish Classical Music History requires scientific data on composers, their compositions, periods, institutions, genres and forms. In this respect, different musical notations that recorded the same musical tradition are the most important sources. Discovering a forgotten composition by a composer who’s thought to have lived 400 years ago is a proof of this.

Özet
Reftâr, 17. Yüzyıl Osmanlı Sarayı Haremi’nde yaşamış bir kadın bestekar olarak bilinir ve Reftâr Kalfa, Tanburi Reftâr Kalfa, Musahip gibi unvanlarla nota arşivlerinde adına eserler kaydedildiği görülür. Günümüzde Reftâr’ın Türk Musikisi’nin ilk kadın bestekarı olduğu düşüncesi Kantemiroğlu Edvârı’nda bulunan- Der Makâm -ı Saba ‘‘Sabâ -yı Reftâr’’usüleş Düyek- bir Peşreve dayandırılır.
Bu çalışmada, 19. Yüzyıl başında geliştirilen Hamparsum Musiki Yazısı ile kaydedilmiş el yazması Hamparsum defterlerinden günümüze ulaşanlar incelenmiş ve Reftâr’ın bilinegelen Sabâ Peşrevi’nin yanı sıra bir Sabâ Saz Semâîsi’nin de olduğu saptanmıştır. İstanbul Üniversitesi Nadir Eserler Kütüphanesi’nde bulunan Y.205/3 ve Y. 211/9 arşiv numaralı Hamparsum Defterleri’nde kayıtlı, Sabâ makamında bir Saz Semâîsi’nin iki örneği Batı nota yazısına çevrilmiş ve incelenmiştir. Reftâr’ın bir müzisyen ve kadın olarak Türk musikisi geleneği içinde varoluşunu kavramak üzere, Osmanlı Sarayı’nda musiki yaşamı ve kadının musiki eğitimi tarihsel perspektifte ele alınarak incelenmiştir.
Geleneksel Türk Sanat Musikisi Tarihi hakkında yazmak; bestekarlar ve eserleri, dönemler, kurumlar, türler ve formlar gibi konularda bilimsel veriler göstermeyi gerektirir. Bu açıdan bakıldığında, birbirinden farklı ama aynı sesli kültürü aktarmayı amaç edinmiş musiki yazıları en önemli kaynaklardır. Günümüzden 400 yıl önce yaşadığı düşünülen bir bestekar ile ilgili unutulmuş bir esere Hamparsum defterlerinde ulaşmak bunun kanıtıdır.
Modular and scalable automation for field robots
Authors: Osten Julia , Weyers Catrin , Bregler Kevin , Emter Thomas , Petereit Janko 
Published: April 2021

Abstract
This article describes a modular and scalable charging and navigation concept for electrified field robots and other agricultural machines. The concept consists of an underbody charging system on a trailer and a modular navigation box. The underlying conductive charging process is compared to other charging techniques. Charging time in relation to charging current and mean power consumption in field use is displayed. In the navigation box, data of various sensors are combined by means of multi-sensor fusion regarding the precise time of arrival. Time synchronization is achieved by a novel method for compensating the data latency jitter by employing Kalman-based timestamp filtering. Furthermore, navigation functionalities, such as motion planning and mapping, are presented.

Published: April 2021

Abstract
The demand for internet access and data transfer is the key driver of mobile communications technologies. The next step is wireless real-time networking. The “Tactile Internet” demands completely new technologies. Low latency, short response times, high reliability and resilience, a network of edge clouds and security are basic requirements. Therefore, 5G is developed. Novel use cases are industrial automation, autonomous vehicles, e-health, and the Internet of Things. For agriculture, 5G is a crucial technology enabler for robotization and Smart Farming processes. Agriculture needs own ad-hoc radio network solutions to efficiently provide coverage and manage data transfer, privacy and flexibility. The synergy of cellular and local mesh communications can solve the problem of unreliable communication and allows farmers to take full control of their data.
The impacts of mediating the work environment on the mode choice in work trips
Authors: Bria Melchior , Djakfar Ludfi , Wicaksono Achmad 
Published: April 2021

AbstractThe impacts of work characteristics on travel mode choice behavior has been studied for a long time, focusing on the work type, income, duration, and working time. However, there are no comprehensive studies on the influence of travel behavior. Therefore, this study examines the influence of work environment as a mediator of socio-economic variables, trip characteristics, transportation infrastructure and services, the environment and choice of transportation mode on work trips. The mode of transportation consists of three variables, including public transportation (bus rapid transit and mass rapid transit), private vehicles (cars and motorbikes), and online transportation (online taxis and motorbike taxis online). Multivariate analysis using the partial least squares-structural equation modeling method was used to explain the relationship between variables in the model. According to the results, the mediating impact of work environment is significant on transportation choices only for environmental variables. The mediating mode choice effect is negative for public transportation and complimentary for private vehicles and online transportation. Other variables directly affect mode choice, including the influence of work environment.

Published: April 2021

Abstract
Ensemble hydrologic forecasting which takes advantages of multiple hydrologic models has made much contribution to water resource management. In this study, four hydrological models (the Xin’anjiang model (XAJ), Simhyd, GR4J, and artificial neural network (ANN) models) and three ensemble methods (the simple average, black box-based, and binomial-based methods) were applied and compared to simulate the hydrological process during 1979–1983 in three representative catchments (Daixi, Hengtangcun, and Qiaodongcun). The results indicate that for a single model, the XAJ model and the GR4J model performed relatively well with averaged Nash and Sutcliffe efficiency coefficient (NSE) values of 0.78 and 0.83, respectively. For the ensemble models, the results show that the binomial-based ensemble method (dynamic weight) outperformed with water volume error reduced by 0.8% and NSE value increased by 0.218. The best performance on runoff forecasting occurs in the Hengtang catchment by integrating four hydrologic models based on binomial ensemble method, achieving the water volume error of 2.73% and NSE value of 0.923. Finding would provide scientific support to water engineering design and water resources management in the study areas.

Abstract
This study investigated the effect of phenol-formaldehyde (PF) resin treatment on the dimensional stability of birch solid wood and plywood. Therefore, three different low molecular weight PF resins with average molecular weights (M

w
) of 292, 528, and 884 g/mol were synthesized and used for silver birch (Betula pendula) solid wood (20 × 20 × 20 mm3) and veneer (100 × 100 × 1.4 and 300 × 300 × 1.4 mm3) impregnation to produce plywood. The weight percent gain (WPG) and bulking after curing of resin treated wood specimens were determined. The leaching was performed to evaluate the PF resin fixation stability. All tested resins at all concentrations were similarly fixed in wood blocks after the leaching (1.5–2.0% WPG loss). The dimensional stability of birch wood after treatment with all tested PF resins was significantly improved. The anti-swelling efficiency (ASE) of birch wood blocks treated with PF resins after seven water soaking-drying cycles was in the range of 39–53%, 46–65% and 49–65% using 10, 15 and 20% solution concentrations, respectively. Whereas, the ASE of plywood obtained from veneers treated with 10% of PF solution was improved by 6–20%. The equilibrium moisture content (EMC) and volumetric swelling (VS) of PF treated plywood at 98% of relative humidity (RH) decreased significantly. All PF resin treated plywood surfaces were more hydrophobic compared to untreated plywood.

Published: April 2021

Abstract
Modular multilevel converter for high voltage DC system has great potential as the key role in global energy interconnection. Adaptive reclosing or restarting after suffering from short-circuit faults is a critical segment to realize safe and stable operation. An adaptive restart scheme for the half-bridge sub-module transmission system is proposed, which is based on the active current injection of the auxiliary fault discriminate module. Combined with the engineering experience, the transient characteristics of the line current during the fault restart stage are analyzed. The ratio of the current peaks at both ends of the fault point is used as the criterion. Moreover, the restart current suppression strategy is introduced into the adaptive restart scheme. It provides a decision-making basis for discriminate the property of the fault and improves the success rate of fault restart. The simulation results show that after the external auxiliary module is introduced into the adaptive restart stage, the restart current does not exceed the rated value. Finally, The permanent fault and the transient fault can be successfully distinguished, providing a reliable guarantee for the subsequent action decision of the protection devices.

Abstract
A wave equation in a bounded and smooth domain of

with a delay term in the nonlinear boundary feedback is considered. Under suitable assumptions, global existence and uniform decay rates for the solutions are established. The proof of existence of solutions relies on a construction of suitable approximating problems for which the existence of the unique solution will be established using nonlinear semigroup theory and then passage to the limit gives the existence of solutions to the original problem. The uniform decay rates for the solutions are obtained by proving certain integral inequalities for the energy function and by establishing a comparison theorem which relates the asymptotic behavior of the energy and of the solutions to an appropriate dissipative ordinary differential equation.
Normalisation of human chorionic gonadotrophin (hCG) levels in a patient with partial molar pregnancy with a uterine mass without chemotherapy: impact of using herbal remedies
Authors: Ismail Norzila , Zainudin Aida Maziha , Hua Gan Siew 
Published: April 2021

Abstract

Objectives
Level of βhCG and the presence of any uterine mass of hydatidiform mole need a careful review or monitoring in order to prevent metastasis, provide an early treatment and avoid unnecessary chemotherapy.

Case presentation
A 36-year old fifth gravida patient who had a missed abortion was diagnosed as having a molar pregnancy with beta human chorionic gonadotrophin (βhCG) level of 509,921 IU/L. Her lung field was clear and she underwent suction and curettage (S & C) procedure. However, after six weeks, AA presented to the emergency department with a massive bleeding, although her βhCG level had decreased to 65,770 IU/L. A trans-abdominal ultrasound indicated the presence of an intra-uterine mass (3.0 × 4.4 cm). Nevertheless, her βhCG continued to show a declining trend (8,426 IU/L). AA was advised to undergo a chemotherapy but she refused, citing preference for alternative medicine like herbs instead. She opted for an “at own risk” (AOR) discharge with scheduled follow up. Subsequently, her condition improved with her βhCG showing a downward trend. Surprisingly, at six months post S & C, her βhCG ameliorated to 0 IU/L with no mass detected by ultrasound.

Conclusions

Brucea javanica fruits, Pereskia bleo and Annona muricata leaves can potentially be useful alternatives to chemotherapy and need further studies.
Use of complementary and alternative medicines (CAM) among Malaysian cancer patients for the management of chemotherapy related side effects (CRSE)
Authors: Syed Mohammad Salleh Sharifah Nadia , Farooqui Maryam , Gnanasan Shubashini , Karuppannan Mahmathi 
Published: April 2021

Abstract

Objectives
Chemotherapy-related side effects (CRSE) are among the most distressing events cancer patients face. Some patients seek complementary and alternative medicines (CAM), increasing the risk of undesirable drug- CAM interactions. This study aims to identify the prevalence and type of CAM used for CRSE among cancer patients and patient’s disclosure of CAM use to their prescribers.

Methods
This was a questionnaire-based, cross-sectional study. Data was collected from cancer patients attending to three departments: surgical, medical and gynaecology at a local hospital in Malaysia. Ethical approval was obtained from the Medical Research Ethics Committee, Ministry of Health, Malaysia.

Results
A total of 273 patients were recruited. Prevalence of CAM used for CRSE management was 166 (60.8%). Of the CAM users, 144 (86.7%) were female, 102 (61.4%) were employed and 123 (74.1%) were married. Breast cancer patients were found to be the highest users of CAM (n=76; 45.8%). The top three CAM used by patients in managing CRSE were dietary supplements (n=166; 100%); herbal products (n=154; 92.8%) and traditional Malay therapy (n=147; 88.6%). About 83% (n=137) patients disclosed CAM use to their prescribers. Among these, 58 (42.3%) reported that their doctors encouraged the use, whereas 89 (65.0%) patients claimed their doctors disagreed the use of CAM.

Conclusions
Prescribers still have doubt in combining chemotherapy with CAM, hence patients use CAM discreetly. Increasing the awareness and understanding of CAM use are mandatory to distinguish its possible synergistic or adverse reactions with cancer patients.

Abstract

Objectives
Madhulai Manappagu – a well-known sastric and widely prescribed Siddha herbal syrup formulation indicated for treating Veluppu Noi (Anaemia especially Iron deficiency Anaemia) has been in day today practice in Tamil Nadu for a quite longer decades. The syrup is a herbal preparation which has a sweet pleasant odour and a palatable taste, contain the juice of pomegranate (Punica granatum L.) as the main ingredient. Though the formulation is a fruit juice, the safety profile of the syrup is not established and is being marketed without toxicological evaluation. The study is aimed at ascertaining the acute and sub-acute toxicity assessment of Madhulai Manappagu in Wistar Albino rats.

Methods
The acute and sub-acute (28day repeated oral) toxicity studies were performed as per the guidelines mentioned in the Organization for Economic Cooperation and Development (OECD) 423 (adopted on December 2001) and TG 407 (adopted on October 2008) with slight modifications respectively. For acute toxicity study, three female rats were randomly selected as control; three female rats were randomly selected and were administered a single dose of 5,000 mg/kg body weight per oral route. For sub-acute (28day repeated oral) toxicity studies, three doses of test drug MM of 500 mg/kg/day (low dose), 750 mg/kg/day (intermittent dose) and 1,000 mg/kg/day (high dose) were selected for administration. Both sexes of Wistar Albino rats were randomized into four groups of 10 animals each (five males, five females). Group I was kept as control group. Group II, III and IV served as low, intermittent and high doses of MM respectively. Animals were observed for mortality, morbidity, body weight changes, feed and water intake. Haematology, clinical biochemistry, electrolytes, gross pathology, relative organ weight and histopathological examination were performed.

Results
In the acute toxicity study, rats showed no toxicological signs on behavior, gross pathology and body weight of rats when treated with a single dose of 5,000 mg/kg body weight per oral route. In the subacute (28 days repeated oral) toxicity study, rats have showed no significant changes on behavior, gross pathology, body weight, and hematological and biochemical parameters when treated with Madhulai Manappagu in three different doses.

Conclusions
The toxicity studies which include both acute and 28 days repeated (subacute) oral toxicity studies, revealed no observed adverse effect level (NOAEL) of Madhulai Manappagu in animals. Thus the safety of the drug in human usage was ensured.
Inverse problems for finite Jacobi matrices and Krein–Stieltjes strings
Authors: Mikhaylov Alexander , Mikhaylov Victor 
Published: April 2021

Abstract
We consider dynamic inverse problems for a dynamical system
associated with a finite Jacobi matrix and for a system describing
propagation of waves in a finite Krein–Stieltjes string. We offer
three methods of recovering unknown parameters: entries of a
Jacobi matrix in the first problem and point masses and distances
between them in the second, from dynamic Dirichlet-to-Neumann
operators. We also answer a question on a characterization of
dynamic inverse data for these two problems.

Published: April 2021

Abstract

Objectives
Given their established role in hepatic function and insulin resistance for adults, early screening of type 2 diabetes mellitus (T2DM) in the pediatric population may potentially be improved by the assessment of elevated liver enzymes.

Methods
Our study enrolled 151 nondiabetic children aged 10–14 years. Patients were assessed for demographics and five risk factors for T2DM. The levels of γ-glutamyl transpeptidase (GGT), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) levels were determined in serum samples. The effects of demographics and risk factors on abnormal liver enzyme levels were assessed with univariate chi-square analyses and also with multivariate logistic regression analyses, which were controlled for gender.

Results
Frequencies for abnormal liver enzyme values were as follows: 13 (9%) for GGT, 5 (3%) for ALT, and 20 (13%) for ALP. Across analyses, two results were consistently statistically significant. Females were more likely to have abnormal ALP levels, and patients with BMI percentile ≥95% and with acanthosis nigricans were more likely to have abnormal GGT levels.

Conclusions
Our study suggests GGT as potential marker for T2DM discovery in children. Subsequent long-term longitudinal studies would help to more clearly delineate GGT’s association with T2DM. Additionally, future studies that elucidate the molecular contribution of GGT elevation to T2DM pathogenesis are needed.
