Authors: Yong L K , Law P L , Taib S N L , Ngu J O K , Mah D Y S , Law S L G 
Published: March 2021

Abstract
This study investigates the effects of topography on the amount of sediment yield under simulated rainfall. The slope gradient and length would affect the runoff depth (V) and peak flow volume (Qp) and thus the amount of surface runoffs. In this study, the simulated 150mm/hour rainfall intensity was applied on triangular prism-shaped, cone-shaped and pyramid-shaped models for determination of the amount of respective sediment yields (tons/storm event). It was observed that the sediment yields of the triangular prism-, cone- and pyramid-shaped amounted to 0.144, 0.143 and 0.125 tons/storm event, respectively. The triangular prism-shaped topography has the highest sediment yield amount as it experiences highest runoff depth and highest surface runoff velocity at downslope. Based on the experimental outcomes, it was shown that MUSLE could over-estimate sediment yield as much as 3.6 times for areas characterized by hilly landscape.

Abstract
The aim of this paper is to estimate the response spectra for moderate seismic area in Sarawak, Malaysia. In the present study, the response spectra for Miri district, in Sarawak, has been obtained by using 1-D equivalent linear site response analysis at 114 borehole locations. All the borehole sites are classified based on average shear wave velocity (Vs30) as per Malaysia National Annex to Eurocode 8 (MNA-EC8) site classifications using the geotechnical relationship. In this study, the input motion was selected from Pacific Earthquake Engineering Research (PEER-NGA) online database compatible with target response spectra of Sarawak at engineering bedrock by considering the seismic hazard map for 2475 years as return period and by following the 475 years return period as shown in (MNA-EC8). From the results of this study, it was found that the maximum response spectral acceleration (response spectra with 5% damping) is 2.25 g, 3.25 g and 1.7 g at the ground surface for MNA-EC8 site classes C, D and E respectively. It was also found that the results are under the provisions of seismic design code of Malaysia. The suggested results in this study can be used as a reference in Malaysia to support the MNA-EC8.

Abstract

This paper This paper investigated the effects of binder-aggregates proportion on the performance of one-part geopolymer mortars. High calcium fly ash together with sodium metasilicate have been utilized as the binder, the powdered sodium metasilicate activator was kept at 12% by weight of the fly ash. Three types of mortars were produced with a different binder to fine aggregates proportions (B: A) of 1: 0.5, 1:1, 1:2. The strength properties of the one-part geopolymer mortars (OPGM) which comprises compressive, flexural, splitting tensile strength and water absorption have been investigated. At 28 days of outdoor curing, the OPGM exhibited compressive strength of 50 MPa and 43 MPa at ambient curing. The flexural strength of the OPGM represents 16 – 17 % of its compressive strength. Regardless of the curing techniques, the strength properties of the OPGM is almost the same. The optimum OPGM was found to be at 1: 0.5 binder-aggregates proportions at outdoor curing.

Published: March 2021

Abstract
Landslide Susceptibility Mapping using GIS software and remote sensing data have been conducted in several location involving geological and geomorphological sensitive at Canada Hill, Miri. The previous researcher has conducted quantitative analyses using different statistical methods with different parameters in the same study area. The mapping of landslides using high-resolution Airborne LiDAR data is a valuable effort. All of this play important role, in the analysis and development of landslide susceptibility map. High-resolution Airborne LiDAR data has the ability to penetrate thick forest cover and produce Digital Terrain Model. Using Digital Terrain Model, the landslide parameter can be generated and extracted. The main objective of this study was to produce landslide susceptibility map using the Probability Frequency Ratio Model method. This study involved the delineating of causative factors from Digital Terrain Model generated by Airborne LiDAR data as well as the data collected from the field. Apart from parameters derived from LiDAR, parameters from filed and site investigation were included into the mapping process. This study was different from the previous studies in the same area in terms of various analytical approaches and samples used. The results of the landslide susceptibility map were verified via randomly selected landslides samples using two different methods. The landslide susceptibility map produced is more refined and is able to predict more effectively compared to the existing map. The landslide susceptibility map produced in this study could be used for land use planning and management by decision makers and land use planners.

Published: March 2021

Abstract
Wood carving has a long history in Malaysia. It is greatly influenced by the rich landscape of tropical forest in the living environment of the locals. The motifs of the carving are primarily derived from the images of flora and fauna. It mimics the intricate nature of leaves and flowers of the plants. The craftsmen initially use the bas-relief design consisting also of animal imageries on the boat’s sides or sometimes on the house components and even the dagger handle. However, with Islam’s arrival in the early 15th century, due to its teachings, contributed to the ban of animal images on art form. While most of the carvings are done on wood, there is no ample evidence of records available due to time and tides of the decaying process of the artwork. Likewise, there is no extensive research and documentation produced by academics to record the traditional wood carving of the Malays. Although few collections had documented the contemporary Malay houses produced by local scholars, sadly, there was no recount on the importance of housing elements and the technique of construction neither on wood carving. Hence, this paper attempts to examine the influence and pattern of wood carving on traditional mosques in Kelantan and Terengganu. The research conducted case studies, to seek the signs of the features and elements of wood carving on the traditional mosque in Kelantan and Terengganu, disclosing the influence of patterns and motifs on the selected images of its architecture. A measured drawing technique commonly used in conservation works guided the research operation which comprised of hand-drawn sketches to capture the details, measurement of building components, as well as transferring the images using tracing paper, while the other methods in gathering the information extended to direct interviews and photography. Then, the data collected were analyzed to determine the differences of each carving patterns and motifs in the two mosques in Kelantan and Terengganu. The result of the research established the future records on the variety of motifs and patterns of the Malay wood carving. Subsequently, it further elaborates the extensive techniques of wood carvings system and records the patterns found at Kelantan and Terengganu’s mosques for future inventory and recorded history.

Published: March 2021

Abstract
The eclecticism approach is unconsciously applied in the design process by selecting elements considered as the best elements from different architectural styles or eras to produce a new distinctive building model commonly applied by architects in design. Nowadays, the combination of various architectural elements from different styles into one building is often created, especially in Malaysia. In this research, the author focuses on the design of mosques in Kuching. Throughout history, the Masjid Bandaraya Kuching (known as Masjid Bahagian Kuching by the locals) has undergone four (4) stages of transformation process since it was first built in 1840 A.D until the latest changes that took place in 1968 A.D. This study aims to reveal the eclecticism approach applied in every stage. Qualitative method is applied in this research by examining the photographs from the archives and analysing the longitudinal timeline and cases through the history of Kuching, literature and observations concerning the Masjid Bandaraya Kuching to understand the initial forms and changes that have occurred from the past to the present. The analysis takes into account both comparative and contextual analytical techniques to represent a close interpretation. Findings indicate that the building of Masjid Bandaraya Kuching has been transformed through the traditional eclecticism as well as radical eclecticism approach.

Abstract

Assistive and rehabilitative robotics technologies have seen increasing adoptions in the industry and medical applications alike. This paper presents the dynamic modelling and control scheme of a single arm robotic exoskeleton that is aimed for rehabilitation and physiotherapy of upper limbs. The dynamic model was developed using Euler-Lagrange formulation and the obtained equations allow close analysis on different sources of dynamic torques, which exhibit highly non-linear behaviour. A hybrid hierarchical control scheme employing sliding mode (SMC) and PID controllers are proposed. Simulation were setup using Simulink to evaluate the ability of the proposed control scheme. The simulation results are presented and they show that the proposed control scheme was able to control and track the desired trajectory for multiple degrees-of-freedom.

Abstract
Titanium alloy Ti-6Al-4V properties advantage gives it a well-known reputation for decades as a reliably material used in a wide range and specific application of resistance spot welded joint such as automotive & aviation products. High strength joint is created depends on the welding parameters used in resistance spot welding. Particular problems occurred about the effect of welding parameters on pure titanium and titanium alloy mechanical and physical properties from previous researches. Some pores and acicular α’ phase appeared in the microstructure, which caused partial interfacial failure mode in the tensile testing. This study is conducted to study the influence of welding parameters for Ti-6Al-4V weld nugget mechanical and physical properties and discover its optimum level of parameters. Tensile-shear testing is used to observed the optimum level. In the optimum level microstructure result reveals that in the weld nugget zone as a fusion zone the lamellar α+β is dominantly observed, this contrasts sharply with the base metal and the heat-affected zone where the primary α and β phase appear to be more dominant. The highest hardness value is discovered in the weld nugget area near the center proving the contribution of the lamellar α+β on this area.

Abstract

Futsal research on the ball characteristic has received little scientific attention. Recently modern football has been developed that afford excellent ball control and delivering. Difference constructions and sizes of ball deliver different characteristics of the ball. The purpose of this study is to examine Futsal ball size four deformations and coefficient of restitution (COR) during the impact. In this study, the Futsal ball was dropped vertically under three conditions. A subject performed five repetitive drops off the ball to impact a steel plate. The ball velocity was measured by SparkVue motion sensor attached on the top of the apparatus while the deformation was recorded using a high-speed video camera, that can up to 1,000 frames per second. From the experiment, the ball deformation and COR were measured. The results obtained showed the deformation and COR value vary with different heights for the same type of Futsal ball size four. It shows that the different heights of ball drops give different ball impact characteristics. It was found that the COR depended on the amount of the deformation of the ball.

Abstract
Hydrogen has a great potential as an alternative energy and produces zero emissions, but most of hydrogen is produced from non-renewable fossil fuels via reforming. Thus, biomass is a promising replacement to fossil fuels where hydrogen can be sourced from. In this project, sago waste is chosen as raw material in a microbial electrolysis cell (MEC) to produce hydrogen fuel. A mathematical model with the integration of MEC with photo-fermentation has been developed and modified by using sago effluent as a substrate in a batch process. The main parameter such as concentration of microbial community has been observed in this project as it gives a huge influence on the gas product of MEC. In conclusion, the develop model was to observe the behavior of the microbial electrolysis cell where a maximum of 3.8 L/day (t = 4 days) of hydrogen production and 0.38A of MEC current were obtained.

Abstract

Sago starch has multiple applications in industries such as textile, cosmetics and pharmaceutical, paper and wood. This study focuses on the utilization of sago starch to promote formaldehyde-free adhesives. Formaldehyde-based adhesive commonly used in wood industry emits formaldehyde, which is classified as carcinogen, into the air that has raised concerns over the potential hazards to human health. Sago starch-based adhesive was produced by blending the sago starch with sodium hydroxide (NaOH) and glycerine. Fourier-Transform Infrared Spectroscopy (FT-IR) was used to characterize the chemical changes in the sago starch-based adhesive. The quality of sago starch adhesive was tested according to their viscosity. The mechanical property is analyze based on lap shear (bond) strength of the sago starch adhesives according to ASTM D907 and D143 by using Model D350 Testomeric. Parameters affecting the viscosity of the sago starch-adhesive such as time, temperature, concentration of sodium hydroxide, and the amount of glycerine were studied. The viscosity of the sago starch-based adhesive decreased as the mixing time, temperature, concentration of NaOH and the amount of glycerine increased.
Arbitrary complex retarders using a sequence of spatial light modulators as the basis for adaptive polarisation compensation
Authors: Hu Qi , He Chao , Booth Martin J 
Published: March 2021

Abstract
We show theoretically how a sequence of spatial light modulators (SLMs) can be used to compensate polarisation and phase errors introduced by a spatially variant homogeneous waveplate with any polarisation eigenmode and arbitrary retardance distribution. The resultant compensation is applicable to all pure input polarisation states. The properties of such a system are easily described using Jones calculus in terms of the retardance distribution on each SLM. However, it is not straightforward to determine from the Jones matrices the arrangements nor the settings of each SLM required to implement an arbitrary spatially variant retarder. In order to address this problem, analytic solutions for the required SLM settings are obtained through the construction of a geometrical model on the Poincaré sphere. These solutions are validated against numerical models. These models can be used, for example, to control a multi-pass SLM system acting as the correction device in an efficient vectorial adaptive optics system.

Published: March 2021

Abstract

Objectives
Hemangiopericytomas (HPCs) and solitary fibrous tumors (SFTs) were considered two distinct entities, but a common gene fusion, NAB2-STAT6, has been identified in both. Although rare, HPCs and SFTs do metastasize, some many years later after resection. Given the extended disease-free interval, it can be difficult to determine with certainty if an HPC or SFT at a new anatomic location represents a second primary or metastatic disease.

Methods
RNA was extracted from formalin-fixed, paraffin-embedded tissue of two patients with multiple SFT/HPC samples. The fusion gene was amplified by reverse transcription polymerase chain reaction (RT-PCR) and a custom-designed Archer FusionPlex panel (94 target genes) and the Illumina NextSeq 550.

Results
We identified two patients with multiple resections for HPC/SFT during 26 years at our institution. The first patient had a history of HPC and almost 10 years later she was diagnosed with malignant SFT. The HPC and the SFT shared the same fusion breakpoint. The second patient had multiple lesions in the brain and bone/soft tissue over a 27-year span following a diagnosis of meningeal SFT. Three lesions from this patient shared the same fusion breakpoint.

Conclusions
Our study demonstrated the same fusion breakpoints in primary and metastatic SFTs/HPCs at different time points using both RT-PCR and the Archer fusion panel.

Published: March 2021

Abstract

Objective
In the background of a large population of bilinguals globally, the study aimed to develop standards of neuropsychological testing in the context of bilingualism. Because bilingualism is known to affect cognitive processes, bilinguals and monolinguals were compared on their performance on cognitive tests, to investigate the possibility of the need for separate normative data for the two groups.

Method
A comprehensive neuropsychological test battery, standardized across five Indian languages: the Indian Council of Medical Research-Neuro Cognitive Tool Box (ICMR-NCTB) was administered to 530 participants (267 monolingual and 263 bilinguals matched for age and education). A systematic method of testing cognition in bilinguals was developed; to identify the appropriate language for testing, ensure language proficiency of examiner, and to interpret the bilingual responses. Additionally, the performance of bilinguals on the ICMR-NCTB was compared with monolinguals.

Results
Cognitive testing in the bilingual context was performed in the most proficient language of the participants, by examiners well versed with the language. Results from the language-based tests suggested that the frequent occurrence of borrowed- and language-mixed words required consideration while scoring. The reported bilingual effect on cognitive processes did not reflect as differences in the performance between bilinguals and monolinguals.

Conclusions
Observations from the study provide robust recommendations for neuropsychological testing in the context of bilingualism. Results indicate that separate normative data may not be required for bilinguals and monolinguals. The study will be relevant and provide a reference framework to address similar issues in the large population of bilinguals in other societies.

Published: March 2021

Abstract
Cancer is one of the most prevailing, deadly and challenging diseases worldwide. The advancement in technology led to the generation of different types of omics data at each genome level that may potentially improve the current status of cancer patients. These data have tremendous applications in managing cancer effectively with improved outcome in patients. This review summarizes the various computational resources and tools housing several types of omics data related to cancer. Major categorization of resources includes—cancer-associated multiomics data repositories, visualization/analysis tools for omics data, machine learning-based diagnostic, prognostic, and predictive biomarker tools, and data analysis algorithms employing the multiomics data. The review primarily focuses on providing comprehensive information on the open-source multiomics tools and data repositories, owing to their broader applicability, economic-benefit and usability. Sections including the comparative analysis, tools applicability and possible future directions have also been discussed in detail. We hope that this information will significantly benefit the researchers and clinicians, especially those with no sound background in bioinformatics and who lack sufficient data analysis skills to interpret something from the plethora of cancer-specific data generated nowadays.

Published: March 2021

Abstract

Summary
T cells play a critical role in cellular immune responses to pathogens and cancer and can be activated and expanded by Major Histocompatibility Complex (MHC)-presented antigens contained in peptide vaccines. We present a machine learning method to optimize the presentation of peptides by class II MHCs by modifying their anchor residues. Our method first learns a model of peptide affinity for a class II MHC using an ensemble of deep residual networks, and then uses the model to propose anchor residue changes to improve peptide affinity. We use a high throughput yeast display assay to show that anchor residue optimization improves peptide binding.
