Impacts of ecosystem vitality on ASEAN’s agricultural exports: A System Generalized Method of Moments approach

This study examined the impact of the Association of Southeast Asian Nations (ASEAN)’s ecosystem vitality (EV) on its agricultural exports to the rest of the world. Using a sample of the six major ASEAN countries (ASEAN-6) (including Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) and their 72 trading partners for the period 2007–2016, we found robust evidence of a positive relationship between the quality of EV and the volume of agricultural exports. At the sectoral level, the quality of EV had the most substantial effects on the ASEAN’s exports of SITC-0 (food and live animals) and exerted the least impact on the ASEAN’s exports of SITC-2 (crude materials, inedible, except fuels). This empirical evidence implies that natural resource-intensive products are more sensitive to the quality of EV. At the country level, EV has the most potent effect on the ASEAN’s agricultural exports to high-income countries and the least impact on the ASEAN’s agricultural exports to low-income countries. To promote agricultural exports, especially to high-income countries, our empirical results suggest that ASEAN countries need to build specific and effective plans for conservation of environment and management of sustainable ecosystems.

CO Hydrogenation on a Nickel Catalyst: II. A Mechanistic Study by Transient Kinetics and Infrared Spectroscopy

The CO hydrogenation into methane was studied over a Ni/SiO2catalyst by means ofin situtransient techniques (DRIFT, SSITKA) in order to have access to a detailed description of the reacting surface and to understand the ageing process related to the kinetic behaviour at steady state. After an initial period of carbon deposition, fast sintering, and particle smoothing via nickel carbonyl transfer, the reacting surface can be described as a monolayer of nickel carbide, largely covered by CO adspecies with an average bonding stoichiometry of CO/2Nis. The rate of hydrogenation is controlled by the probability for a hydrogen molecule to collide with an active site formed of one to two adjacent Ni atoms free from adsorbed CO. The concentration of active sites is statistically determined by the CO coverage. Carbon atoms belonging to the carbidic layer associated to the active site are hydrogenated by hydrogen activated on the free Ni atoms. The regeneration of the carbidic layer is in turn ensured by CO dissociation after methane desorption. A rate equation is presented with physically meaningful kinetic parameters.
Assessing the key game-related statistics in Brazilian professional basketball according to season phase and final score difference

ABSTRACT This study aimed to identify the game-related statistics that best discriminate winning and losing teams during the regular season and playoff phase of Brazilian professional basketball. Data were retrieved from game-related statistics of 1271 games (1048 from regular season and 223 from playoffs phase) of five seasons between 2014 and 2019 of the Brazilian professional basketball league [Novo Basquete Brasil (NBB)]. All games were clustered into close, balanced, and unbalanced games. A discriminant analysis was performed. Results showed that defensive rebounds (SC = 0.407) were determinant to win close games in the regular season, while defensive rebounds, assists, and 3-point shooting efficiency were determinant (SC > 0.3) to win balanced and unbalanced games in this phase. In the playoff phase, winning teams performed more defensive rebounds and assists (SC > 0.3), having relevant contribution of 3-point shooting efficiency (SC = 0.311) in close games, and 2-point shooting efficiency (SC = 0.336) in balanced games. These findings should be useful for coaches to plan training and playing strategies emphasising the game-related statistics that are more determinant to the game outcome.
The Influence of Prevailing Regional Political Narratives on Intuitions Featured in Religious Messages

Recent research suggests that political beliefs in different geographic locations shape religious groups’ sensitivity toward and representation of moral intuitions. Guided by moral foundations theory, we test this possibility with content analysis. We compared moral intuitions represented in church sermons of one religious denomination located in counties with liberal versus conservative voting records. Fifty-eight sermons based on identical biblical texts were selected from churches located in 28 liberal and 30 conservative counties throughout the United States. Chi-square analyses revealed: (1) sermons from conservative counties featured more moral intuitions overall than sermons from liberal counties, and (2) ingroup loyalty was overrepresented in sermons from conservative counties.
Effects of Nutritional Supplements on Judo‐Related Performance: A Review

Abstract The potential ergogenic effect of nutritional supplements depends on their dosage and the type of exercise executed. Aiming at reviewing the research literature regarding sport supplements utilized in judo in order to improve performance, a literature search was performed at the following databases: Dialnet, PubMed, Scielo, Scopus and SportDiscus. A total of 11 articles met the inclusion criteria and were selected. Evidence revised indicates that supplementation with caffeine, β-alanine, sodium bicarbonate, creatine, and β-hydroxy-β-methylbutyrate has a positive effect on judo-related performance. Moreover, there is evidence suggesting that combining some of these nutritional supplements may produce an additive effect.
In-Season Assessment of Sprint Speed and Sprint Momentum in Rugby Players According To the Age Category and Playing Position

Abstract The purpose of this study was to investigate the interval in which male rugby union players reach maximum speed in a 50 m sprint according to age categories and playing positions. This study also aimed to establish the optimal distance for the assessment of sprint speed and to compare the differences in anthropometrics, sprint and sprint momentum according to the age and playing position. Three hundred amateur rugby players performed anthropometric and physical fitness tests (10, 20, 30, 40 and 50 m sprint times, acceleration, velocity, and sprint momentum) during the in-season period. Participants from different age categories (under 14’s (U14), under 16’s (U16), under 18’s (U18) and Seniors) and positions (forwards and backs) volunteered to participate in this study. Results revealed that most of the U14 and U16 players (58.2% and 55.3%, respectively) reached maximum speed in the interval between 20 and 30 m with lower sprint speed than U18 players and Seniors (44% and 49%, respectively). Comparisons between each interval showed significant differences for all U14 and U16 forwards, suggesting the fastest interval was between 20-30 m. No significant differences were found for U16 backs, U18 and Seniors, between sprint times in the 20-30 m and 3040 m intervals. In addition, between-group comparisons, demonstrated significant (p < 0.001) differences in U14 when compared to U16, U18 and Seniors in anthropometric variables, sprint times and sprint momentum. In conclusion, this study suggests that the optimal distance for the assessment of sprint speed of rugby players is 30 m and that body mass, sprint momentum and sprint speed clearly discriminate between players of different age categories and playing positions.
Physiology of Basketball – Field Tests. Review Article

Abstract The game of basketball is characterized by short and intense bouts of activity at medium to high frequency. Basketball entails specific types of movements, physiological requirements and energy sources. The duration of physiological responses involving ATP, CP and glycolysis responses to this type of activity is 5-6 seconds for a single sprint, and a contribution of the aerobic system is of less than 10%. Recovery periods in basketball, as a rule, are not long enough to fill the gap for such high intensity activities. It is hard to achieve the same level of performance consistently over time in repeated sprints. This means that basketball players need great athletic ability in order to demonstrate speed, strength and power required to produce a successful performance most proficiently. Therefore, tests are needed to help coaches to monitor their players and ensure that they have the physiological capacity required for the game. The aim of fitness tests is to assess the condition of athletes in terms of each fitness component, in order to determine what needs to be improved through the training program and to conduct retests at set times to assess whether their condition has changed. The literature offers a number of widely used tests to measure aerobic and anaerobic fitness. This article reviews the physiological demands of basketball and analyzes the field tests commonly used at present. The article emphasizes the need for a specific test that will serve coaches and physical fitness trainers in monitoring their players.
Inhibition of nitrogen mineralization in young humic fractions by anaerobic decomposition of rice crop residues

Field observations indicate a long‐term decrease in crop uptake of N derived from soil organic matter under continuous production of irrigated lowland rice (Oryza sativa L.). Decreased availability has been associated with an accumulation of phenolic lignin residues in soil organic matter, which can chemically bind N. To evaluate the hypothesis that the decrease in N availability results primarily from anaerobic decomposition of incorporated crop residues, 15N‐labelled fertilizer was applied three times during one growing season in a field study that compared anaerobic decomposition with aerobic decomposition for annual rotations of rice (Oryza sativa L.)–rice and rice–maize (Zea mays L.). Contents of 15N and total N during the growing season were measured in humic fractions and total soil organic matter. Results indicated an inhibition of N mineralization for the rice–rice rotation with anaerobic decomposition of crop residues, both for 15N that was immobilized after application and for total N. The inhibition was strongest for 15N that was applied at planting. It became more evident as the season progressed and reached significant levels during mid‐season stages of plant growth when crop demand for N peaks. These results were clearest for a young, phenolic‐rich humic fraction that was active in 15N immobilization and remineralization. Comparable but less significant trends were evident for a more recalcitrant humic fraction and for soil organic matter. Trends in crop‐N uptake associated the combination of rice–rice rotation and anaerobic decomposition with inhibited uptake of soil organic N but uninhibited uptake of fertilizer N. Increased aeration of rice soils through aerobic decomposition of crop residues or crop rotation is a promising management technique for improving soil N supply in lowland rice cropping.
Antifungal Activity and Chemical Composition of Essential Oil of Origanum Hypericifolium

Endemic oregano's, Origanum hypericifolium O. Schwartz and P.H. Davis, essential oil was extracted to exert its biological activity in vitro. Fifteen components in its extracts performed by hydro distillation. The major components in the fruit and flower volatiles of O. hypericifolium were p-cymene (34.33 g/100 g oil), carvacrol (21.76 g/100 g oil), thymol (19.54 g/100 g) and γ-terpinene (13.91 g/100 g oil). The antifungal activity of O. hypericifolium’s oil was evaluated against 14 fungi isolated from hazelnut and walnut. Nuts are capable of harboring toxigenic fungi and the threat of mycotoxin contamination on them exists. Essential oil of O. hypericifolium was found to be active both in contact and headspace assays in vitro producing hyphal growth inhibition. In the contact assay, P. frequentans was found to be the least sensitive species. The more sensitive species were P. castellonense, P. verrucosum. var. cyclopium, C. globosum, and A. kiliense. Their growth was completely (100%) inhibited at days 3 and 6. In the volatile assay, all the mycelial growth of all tested fungi was completely inhibited at day 3. The volatile activity was found to be highly efficient than that of contact activity assay. This could be because of the aromatic contents of Origanum, such as monoterpenes, carvacrol, thymol, and p-cymene.
Manufacture of processed cheese from Iraqi white soft cheese

Processed cheese was made from different samples of Iraqi white soft cheese by adding 3.5% emulsifying salts and 15-25% water depending on the chosen type of processed cheese. Arabic gum was used to firm the cheese at a rate of 0.08%. Total solids ranged from 46.8-43.4% in the firm and spread types, respectively. Laboratory processed cheese gave excellent quality compared with local processed cheese.
Room-Temperature Pulsed Operation of GaInNAs Laser Diodes with Excellent High-Temperature Performance

We have successfully operated GaInNAs laser diodes with a pulsed current at room temperature. The lowest threshold current density was about 0.8 kA/cm2, and the lasing wavelength was about 1.2 µ m. Characteristic parameters such as internal quantum efficiency and the gain constant were measured, and excellent high-temperature performance was observed. The characteristic temperature was 127 K in the temperature range from 25 to 85° C.
Snow Albedo Seasonal Decay and Its Relation With Shortwave Radiation, Surface Temperature and Topography Over an Antarctic ICE Cap

We have characterized the snow albedo decay over Hurd Peninsula, Livingston Island, Antarctica, for the period 2000–2016. The snow albedo was obtained from the MOD10A1 product of the spaceborne MODIS sensor. A low-pass filter is applied to the data in order to eliminate short-term variations and retain the seasonal variation of albedo. The seasonal albedo was fitted to an exponential decay function to obtain the decay rate, the duration and the starting date of the decay. On average, albedo decay starts in late September and lasts for 96 ± 20 days. Snow melting lags behind snow albedo decay. This lag is due, on the one hand, to the occurrence of dry-snow metamorphism and sublimation in the early stages of the decay, and on the other hand to persisting subsurface melting after the completion of the metamorphic processes at the surface. The albedo decay is mainly driven by the shortwave incident radiation, with air and near-surface temperatures unexpectedly playing a minor role. Near-surface-temperature controls the importance of the local topography in the albedo decay. Topography only determines the albedo decay when the snow cover is not homogeneous over the study area.
Symmetric-Mapping LUT-Based Method and Architecture for Computing XY-Like Functions

We propose a new method and hardware architecture to compute the functions expressed as <inline-formula> <tex-math notation="LaTeX">$X^{Y}$ </tex-math></inline-formula> (<inline-formula> <tex-math notation="LaTeX">$X$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$Y$ </tex-math></inline-formula> are arbitrary floating-point numbers), which can support arbitrary Nth root, exponential and power operations. Because of the complexity of direct computation, we usually convert it to logarithm, multiplication, and antilogarithm operations. Traditional approaches suffer from long latency, large area and high power consumption. To solve this problem, we propose a symmetric-mapping lookup table (SM-LUT) to be capable of computing <inline-formula> <tex-math notation="LaTeX">$\log _{2}x$ </tex-math></inline-formula> (<inline-formula> <tex-math notation="LaTeX">$x\in [{1, 2}]$ </tex-math></inline-formula>) and <inline-formula> <tex-math notation="LaTeX">$2^{x}$ </tex-math></inline-formula> (<inline-formula> <tex-math notation="LaTeX">$x\in [{0, 1}]$ </tex-math></inline-formula>) simultaneously. It lays the foundation for computing <inline-formula> <tex-math notation="LaTeX">$X^{Y}$ </tex-math></inline-formula>. To further improve hardware performance of our architecture, we propose a multi-region address searcher to speed up the calculation of SM-LUT. In addition, we use an optimized Vedic multiplier to shorten the critical path and improve the efficiency of multiplication, which is included in computing <inline-formula> <tex-math notation="LaTeX">$X^{Y}$ </tex-math></inline-formula>. Under the TSMC 40nm CMOS technology, we design and synthesize a reference circuit to compute <inline-formula> <tex-math notation="LaTeX">$X^{Y}$ </tex-math></inline-formula> with a maximum relative error of 10<sup>−3</sup>. The report shows that the reference circuit achieves the area of <inline-formula> <tex-math notation="LaTeX">$14338.50~\mu \text {m}^{2}$ </tex-math></inline-formula> and the power consumption of 4.59 mW at the frequency of 1 GHz. In comparison with the state-of-the-art work under the same input range and similar precision, it saves 78.57% area and 80.42% power consumption for <inline-formula> <tex-math notation="LaTeX">$\sqrt [N]{R}$ </tex-math></inline-formula> computation and 82.89% area and 81.89% power consumption for <inline-formula> <tex-math notation="LaTeX">$R^{N}$ </tex-math></inline-formula> computation averagely. On top of that, our architecture reduces the computation latency by 62.77% averagely and has one more order of magnitude of energy efficiency than others.
Performance of iterative Successive interference cancellation receiver for LDPC coded OTFS

Orthogonal Time Frequency Space (OTFS) modulation is a recently developed transmission technology, where contellation symbols are placed in the delay Doppler lattice. It is shown in literature that, OTFS is more resilient to inter carrier interference than OFDM. However, the required signal processing complexity of OTFS at the receiver side is much higher than that of OFDM. In this work we present the performance of an iterative SIC receiver for LDPC coded OTFS based on a earlier developed MMSE receiver. It is observed that improvement up to 7.5 dB can be achieved using the proposed receiver. It is also shown that the proposed SIC receiver has lower complexity than a message passing receiver available in literature, yet provides comparable performance for lower order modulation and low SNR. For higher order modulations and at high SNR the proposed receiver achieves better reliability, i.e. coded block error rates up to 105, which is aligned with the higher reliability requirement of 6G mobile communication systems.
Synthesis of SnO2/MoS2 composites with different component ratios and their applications as lithium ion battery anodes

Owing to their high capacities and ease of synthesis with desired morphologies, two anode materials with great potential, namely SnO2 and MoS2, are selected to form a composite anode, where SnO2 nanoparticles act as spacers to prevent the restacking of MoS2 nanosheets, while MoS2 nanosheets serve as substrates to accommodate the SnO2 nanoparticles. However, the ratio between the two components has a crucial effect on the resultant electrochemical performance. In this work, four sets of composites with different SnO2/MoS2 ratios (SnO2/MoS2-1, SnO2/MoS2-2, SnO2/MoS2-3, and SnO2/MoS2-4) have been synthesized, characterized, and electrochemically tested. Among them, the composite of SnO2/MoS2-3 with an SnO2 : MoS2 mass ratio of around 2 : 1 outperforms the pure MoS2 nanosheets and any other composite, delivering the highest and most stable reversible capacities over a test period of 230 cycles with a current density ranging from 100 to 10 000 mA g−1.
Hardware Implementation for Belief Propagation Flip Decoding of Polar Codes

Belief propagation (BP) decoding has natural advantages in throughput for polar codes to meet high-speed and low-latency requirements. The soft outputs of BP decoding can be utilized further for joint detection and decoding in the baseband communication system. However, its error-correction performance is not comparable with the successive cancellation list (SCL) decoding. Belief propagation flip (BPF) decoding is recently proposed to improve the error-correction performance of BP decoding and indicates the potential to compete with SCL decoding. In this paper, we propose an advanced BPF (A-BPF) scheme that reduces the decoding latency with the help of one critical bit and improves the error-correction performance by the proposed joint detection criterion. To improve area efficiency in the hardware level, an optimized sorting network is proposed and applied for the A-BPF decoder. The decoder is implemented on 65 nm CMOS technology for length-1024 and rate-1/2 polar codes, and the results show that the proposed decoder can achieve a close frame error rate performance to the SCL decoder with four lists and deliver a throughput of 5.17 Gb/s at $E_{b}/N_{0}=4.0$ dB.
A Scalable 128-Channel, Time-Multiplexed Potentiostat for Parallel Electrochemical Experiments

Electrochemical experiments like chronoamperometry or cyclic voltammetry (CV) are essential in the research for novel bioelectrochemical systems. These experiments, executed by a potentiostat, are time-consuming which hinders research progression. To speed up those experiments, this work presents a potentiostat with 128 individual parallel stimulation and sensing channels. A channel architecture exploiting time division multiplexing is developed to minimize the hardware cost and area. Potential control is done in the digital domain using 128 individual Linear Quadratic Integral (LQI) controllers. The 128-channel potentiostat is implemented with Printed Circuit Board (PCB) technology and has <inline-formula> <tex-math notation="LaTeX">$16 {\times }$ </tex-math></inline-formula> more channels than the state of the art low-cost potentiostats with a <inline-formula> <tex-math notation="LaTeX">$4 {\times }$ </tex-math></inline-formula> lower cost-per-channel (5 $) and a <inline-formula> <tex-math notation="LaTeX">$4 {\times }$ </tex-math></inline-formula> lower area-per-channel (<inline-formula> <tex-math notation="LaTeX">${93}\,mm^{2}$ </tex-math></inline-formula>). Using parallelism, chronoamperometry experiments can be done <inline-formula> <tex-math notation="LaTeX">${128\times }$ </tex-math></inline-formula> faster, while a conventional <inline-formula> <tex-math notation="LaTeX">${1}\, mV\,s^{-1}$ </tex-math></inline-formula>-CV can be done <inline-formula> <tex-math notation="LaTeX">$72\,\, {\times }$ </tex-math></inline-formula> faster by sampling instead of voltage sweeping.
