Breaking down barriers: exploring the impact of social capital on knowledge sharing and transfer in the workplace
Authors: Peng Michael Yao-Ping 
Published: August 2024

AbstractThe COVID-19 pandemic has posed formidable challenges to economic mobility and corporate expansion. Among these challenges is its pronounced effect on knowledge innovation, a cornerstone upon which many organizations depend. To re-establish the flow of internal knowledge, organizations are compelled to refine their knowledge management strategies and amplify employees’ motivation and eagerness to share and transfer information. This study delves into the influence of knowledge management processes on employees’ knowledge-sharing and transfer behaviors, viewed through the lens of the social exchange theory. It also probes the role of social capital in fostering and augmenting employees’ involvement in refining these processes. Data was gleaned from 30 information service firms in mainland China, resulting in 483 valid responses. Our findings highlight that both relational and structural forms of social capital positively influence the knowledge management processes, subsequently enhancing employees’ knowledge-sharing and transfer behaviors.
Phytophthora cinnamomi: extent and impact in Two Peoples Bay Nature Reserve, Western Australia (1983–2024)
Authors: Hart Ray P. , Freebury G. , Barrett S. 
Published: August 2024

Context Phytophthora cinnamomi has been present in Two Peoples Bay Nature Reserve in Western Australia for decades, with impacts observed in susceptible plant communities. Aims This study aimed to examine the past and present impact of P. cinnamomi on ecosystems. Methods The distribution of P. cinnamomi was mapped 1983–1995 and reassessed in 2024. The long-term spread of the pathogen was measured. Plant densities were assessed, dry-weight biomass measured, and visits by avifauna quantified in infested and healthy vegetation. The persistence of chlamydospores was assessed. Key results Mapping confirmed the widespread distribution of P. cinnamomi in the Reserve, with some areas mapped as disease-free up to 1995 now infested. Phytophthora dieback has spread in Banksia shrubland at an average of 1.5 m/year over a 33-year period. The density of species from the Proteaceae, Fabaceae, Ericaceae, and Hibbertia was significantly reduced; and the biomass of non-sedge species and visits by avifauna lower in infested compared with healthy Banksia shrubland. However, pockets of healthy habitat persist in infested areas and two highly susceptible Ericaceae (Leucopogon glabellus, Styphelia flavescens) were observed in high numbers in infested vegetation. Recovery of chlamydospores confirmed the persistence of the pathogen behind the dieback front. Conclusions The impact of P. cinnamomi is long term and irreversible, however, some susceptible species may have mechanisms to ensure their persistence through prolific seed production. Implications Protection of areas of healthy susceptible habitat from the introduction and spread of P. cinnamomi, the implementation of existing control measures and research into alternative measures continue to be a priority.
Affleck-Dine leptogenesis scenario for resonant production of sterile neutrino dark matter
Authors: Kasai Kentaro , Kawasaki Masahiro , Murai Kai 
Published: August 2024

Abstract
Sterile neutrino is a fascinating candidate for dark matter.
In this paper, we examine the Affleck-Dine (AD) leptogenesis scenario generating a large lepton asymmetry,
which can induce
the resonant production of sterile neutrino dark matter
via the Shi-Fuller (SF) mechanism.
We also revisit the numerical calculation of the SF mechanism and the constraints from current X-ray and Lyman-α forest observations.
We find that the AD leptogenesis scenario can explain the production of sterile neutrino dark matter by incorporating a non-topological soliton with a lepton charge called L-ball.
Finally, we discuss
an enhancement of second-order gravitational waves at the L-ball decay and investigate the testability of our scenario with future gravitational wave observations.

Abstract
This paper presents a design of single photon avalanche diode (SPAD) light detection and ranging (LiDAR) sensor with 128 × 128 pixels and 128 column-parallel time-to-analog-merged-analog-to-digital converts (TA-ADCs). Unlike the conventional TAC-based SPAD LiDAR sensor, in which the TAC and ADC are separately implemented, we propose to merge the TAC and ADC by sharing their capacitors, thus avoiding the analog readout noise of TAC’s output buffer, improving the conversion rate, and reducing chip area. The reverse start-stop logic is employed to reduce the power of the TA-ADC. Fabricated in a 180 nm CMOS process, our prototype sensor exhibits a timing resolution of 25 ps, a DNL of +0.30/−0.77 LSB, an INL of +1.41/−2.20 LSB, and a total power consumption of 190 mW. A flash LiDAR system based on this sensor demonstrates the function of 2D/3D imaging with 128 × 128 resolution, 25 kHz inter-frame rate, and sub-centimeter ranging precision.

Published: August 2024

Abstract
Boron−nitrogen doped multiple resonance (BN-MR) emitters, characterized by B−N covalent bonds, offer distinctive advantages as pivotal building blocks for facile access to novel MR emitters featuring narrowband spectra and high efficiency. However, there remains a scarcity of exploration concerning synthetic methods and structural derivations to expand the library of novel BN-MR emitters. Herein, we present the synthesis of a BN-MR emitter, tCz[B−N]N, through a one-pot borylation reaction directed by the amine group, achieving an impressive yield of 94%. The emitter is decorated by incorporating two 3,6-di-t-butylcarbazole (tCz) units into a B−N covalent bond doped BN-MR parent molecule via para-C−π−D and para-N−π−D conjugations. This peripheral decoration strategy enhances the reverse intersystem crossing process and shifts the emission band towards the pure green region, peaking at 526 nm with a narrowband full-width at half maximum (FWHM) of 41 nm. Consequently, organic light emitting diodes (OLEDs) employing this emitter achieved a maximum external quantum efficiency (EQEmax) value of 27.7%, with minimal efficiency roll-off. Even at a practical luminance of 1000 cd∙m−2, the device maintains a high EQE value of 24.6%.

Published: August 2024

Abstract
Space exploration continues to inspire humanity, with nanosatellites standing at the forefront of critical sectors like remote sensing, telecommunications, and meteorology. In this panorama, accurately determining their attitude is a considerable challenge. Addressing this, our research delves into the application of the well-known TRIAD algorithm. Utilizing four distinct vectors - two reference and two observed - sourced from solar position vectors and the magnetic field, we implemented the algorithm in the NUCLEO-F303RE microcontroller, equipped with the ARM® Cortex® M4 architecture. By carefully corrupting the observed vectors using data from prospective sensors, realized through the Systems Tool Kit software, we aspired to simulate real-world conditions. While tools like STK® for simulations are not new globally, they remain relatively unknown to many Mexican students. By introducing these resources, we aim to pave the way for future researchers at the Mexican Space Agency (AEM), bolstering Mexico’s ongoing journey in space exploration.
A variational Bayesian based robust filter for unknown measurement bias and inaccurate noise statistics
Authors: Yang Shaohua , Fu Hongpo , Zhang Xiaodong 
Published: August 2024

Abstract
In many practical fields, the unknown time-varying
measurement biases (additive and multiplicative bias) and
heavy-tailed measurement noise caused by some unpredictable
anomalous behaviors may degrade the performance of conventional
Kalman filter seriously. To solve the state estimation problem of
systems with time-varying measurement biases and heavy-tailed
measurement noise, this paper proposes a new variational Bayesian
(VB) based robust filter. Firstly, the non-Gaussian measurement
likelihood probability density function (ML-PDF) with multiplicative
and additive measurement bias is built. Then, the conjugate prior
distributions for unknown bias and noise scale parameters are
selected, and the VB method is utilized to jointly infer the system
state, unknown measurement biases and inaccurate measurement noise
covariance matrix. Finally, a VB based robust filter is derived and
its effectiveness is verified by the numerical simulations.

Abstract
Determination of the selling price is an important part of the commercialization process of researched food products. The food product that had been developed was a snack bar product made from grasshopper flour (Valanga nigricornis Burm.). This research purpose was to determine the selling price of snack bar products made from grasshopper flour based on recipe differences. The method of determining the selling price was the cost-based method. Variations of this method are variable costing and full costing. The result of this research was the chosen recipe for the main snack bar production was recipe two. Recipe two had an additional level of grasshopper flour of 8,39% per batch. The estimated selling price of the grasshopper snack bar product from all of these product recipes was Rp. 10,000.00 – Rp. 14,500.00 per pack containing one snack bar per pack. Based on variable and full costing calculations, recipe two had an estimated selling price of Rp. 11,714.01 – Rp. 13,311.37 and of Rp. 12,242.62 – Rp. 13,912.06 respectively. The nutritional values of recipe two per package were water content of 8.08%; ash content of 2.3919%; protein of 13.894%, fat 25.1424%; carbohydrates of 50.4914%; and total Energy of 483.8245 kcal. This value served as nutrition value information that must be printed on the product packaging label. These research results can be used to help the development and design of scale-up processes to make food products compete in the market.

Authors: Yuliani S , Pratiwi Etty , Ratnaningsih  
Published: August 2024

Abstract
The suitability of carrier materials for the entrapment of bacteria is an important factor in developing biofertilizers as it determines their functional properties during use and storage. This study examines the microscopic structure and entrapment properties of several potential carriers for biofertilizers. The carriers studied included rice straw, sago dregs, cassava dregs, gum, carrageenan, pea fiber, and carboxymethyl cellulose (CMC), all in powder form. The entrapment process was carried out by mixing the bacterial solution (10%) of Rhizobium, Azotobacter, Bacillus, and Methylobacterium with the carrier material by spraying and shaking followed by air drying. CMC and carrageenan exhibited a swollen structure when mixed with a bacterial solution, forming lumps. Gum, pea fiber, sago dregs, and cassava dregs swelled slightly, while rice straw demonstrated a non-swollen fibrous structure. The incorporated bacteria appeared entrapped inside the lumps and/or adhered to the surface of the lumps or fibrous particles. The largest number of bacteria was found in gum (log10 6 – log10 7) and pea fiber (log10 4 to – log10 7), followed by cassava dregs (log10 2 – log10 7), CMC (log10 2 – log10 6), sago dregs (log10 5) and rice straw (log10 3 – log10 4), while no bacteria was observed in carrageenan. Most bacteria survived in the carrier with swelling properties and loose structures. In conclusion, the microstructure of carrier materials provides information that can describe bacterial entrapment properties. This study gives important insight useful in formulating carrier materials for developing biofertilizers.
Potato seed production of G2 from plantlet cutting by setting of population, spacing, and mulch
Authors: Dianawati M , Fahmi T 
Published: August 2024

Abstract
Quick multiplication of potato seeds using plantlet cuttings outside of screen house can accelerate the availability of high quality seeds, especially G2 seeds. However, some obstacles are faced, especially the low adaptation rate of plantlet cuttings. This study aimed to increase the production of potato seed G2 from plantlet cutting by using various population number per hole, spacing, and plastic mulch. The study used a randomized completed block design with three treatment factors and six replications. The first factor was the population number (1, 2, 3, and 4 cuttings per hole). The second was spacing in row (20 and 30 cm). The third was the usage of mulch (yes and no). The results showed that the technology combination of four cuttings per hole, spacing in rows of 30 cm, and mulch had the largest number of total and medium tubers per plant. The population at a planting distance of 30 cm which was reduced in this treatment could be increased by increasing the number of cuttings per hole, so that the total number of tubers remained high, especially when using mulch. Single cutting in no mulch and wider spacing would promote much number of large tubers.

Published: August 2024

Abstract
The use of high-quality seeds from high-yielding rice varieties (HYV) is crucial for enhancing grain yield. Yet, the supply of certified seed meets only 57.3% of the total rice seed demand, leading some farmers to plant non-certified local rice seeds. A study examining the effects of seed sources and fertilization on seed yields was conducted in Bogor Village, Sukra District, Indramayu Regency during the Dry Season of 2019. The treatments consisted of two factors: A. Seed sources (Local non-certified seed (Local-NC), HYV non-certified seed (HYV-NC), and HYV-certified seed) and B. Fertilization methods (Recommended Fertilizer (RF), RF+BioF, RF+P as top dressing, and RF+N as top dressing). These were designed in a Complete Block Design with three replications. Results showed that Local-NC was more susceptible to BPH and RSB than HYV varieties. Additionally, Local-NC had the highest percentage of off-type plants and produced the lowest grain and seed yields. The addition of P or N fertilizer to RF during the heading stage notably improved the panicle number per hill, 1000-grain, seed yields and rendement. Our findings suggest that optimal rice seed yields can be achieved by planting HYV– certified seeds and applying either RF + 18 kg P ha−1 or RF + 11.5 kg N ha−1 as top dressing.

Published: August 2024

Abstract
The growth and yield of maize are significantly influenced by the adequacy of soil moisture during the growth period. Given the uncertain rainfall due to climate change, the availability of water for maize production is becoming increasingly limited, while the demand is rising due to population growth. The extent to which maize yield is affected by soil moisture stress at each phenological stage in dryland areas has not been thoroughly explored. This study aimed to determine the production and biomass of maize at various growth stages due to water stress. Watering using drip irrigation equipped with soil moisture sensors was stopped after the maize plants reached 20, 40, 60 (flowering), 80 days after sowing (DAS), and at harvest. Parameters of biomass, maize yield, and other parameters were determined when the soil’s permanent wilting point reached, and soil samples were taken to determine the moisture content. The results showed that irrigation up to 80 DAS was not significantly different in yield, although it was 30% lower than that irrigation up to harvest. However, irrigation up to 60 DAS reduced the yield by 3.9 times and 4.9 times compared to the yield at irrigation up to 80 DAS (85.897 grams/plant) and at harvest (108.57 grams/plant), respectively. Other parameters, such as dry biomass, cob weight, cob length, and cob diameter followed the yield trend, although their values varied. The dry biomass of maize at irrigation until 20 and 40 DAS were 13.68 grams/plant and 40.05 grams/plant, respectively. The experiment implies that irrigation water should be provided until 80 DAS to minimize significant yield losses of maize in dryland conditions.

Abstract
List profile is a mineral board product that is increasingly in demand by the wider public. One of the advantages of list profiles is that they are cheap, quick to obtain, resistant to attacks by wood-destroying organisms, and can be obtained in the form of attractive ornaments. From an economic perspective, list profile with rofing filler is more expensive. Coconut fiber can be used as a type of filler that has the same strength at a low price. This research aims to determine the type and level of gypsum adhesive, white cement, and their mixtures on the properties of the coconut fiber list profile. The research design used a completely randomized design with Tukey’s follow-up test. The factors used were the type of adhesive (gypsum, white cement, and a mixture of gypsum with white cement), and the amount of adhesive (600 g, 690 g, and 780 g). The parameters observed were water content, density, thickness expansion, and fracture toughness. The research results showed that the type of adhesive had a significant effect on water content and thickness development, the amount of adhesive had a significant effect on density and the adhesive type had a significant effect on water content, while the amount of adhesive had a significant effect on density and thickness development. The average value of water content is 15.90 - 18.85 %, density 0.67 - 0.92 g/cm3, thickness expansion 0.37 - 2.54 % and strength at fracture 3.88 - 35.90 kg/cm2.

Published: August 2024

Abstract
Ensuring food authenticity is integral to quality control and food safety, demanding traceability of food ingredient origins to be prominently featured on labels. Pork, a widely consumed and processed animal protein source, is susceptible to adulteration with wild boar meat, primarily driven by factors such as production costs and profitability. Complicating matters, the quality of wild boar meat obtained through game hunting lacks guarantees for hygienic standards, posing potential harm to consumers. Recent outbreaks of African Swine Fever in pigs and wild boars further emphasize the critical link between food safety and meat authenticity. This study addresses the need for research in distinguishing between pork and wild boar meat to uphold food quality control standards. Establishing the meat origin is not only crucial for quality control but also vital for mapping and tracing meat distribution patterns. The study adopts a DNA-based approach, utilizing biomarkers to distinguish domestic pig and wild boar meat. However, researchers encounter significant challenges due to their shared species (Sus scrofa) and high DNA sequence similarity. The pursuit of robust biomarkers and analytical methods becomes imperative. Exploring both nuclear and mitochondrial DNA, this mini-review outlines the research developments in identifying resilient biomarkers and employing various analytical methods, including conventional PCR, PCR-RFLP, Real-time PCR, microsatellite (STR), and deep sequencing (NGS or GWAS). The paper provides a concise overview of the ongoing efforts to find effective biomarkers and analytical methods based on DNA approaches for distinguishing domestic pigs and wild boars, showcasing their potential applications in food authentication.

Abstract
Indonesia is the fourth coffee producer in the world which is 95% produced by smallholder plantations with various ways of processing and storage in the form of green beans and roasted beans. This study aims to analyse the presence of mycotoxin contamination of Menoreh coffee in various storage levels using Liquid Chromatography tandem High-Resolution Mass Spectrometry (LC-HRMS) analysis. The analysis of mycotoxin contamination in green beans and roasted beans is crucial to ensure the safety and quality of the coffee for consumption. This study used a random sampling method. The samples tested were Menoreh Robusta coffee bean from two processors in Samigaluh, Kulon Progo, Yogyakarta, Indonesia. The results showed that green beans stored in the dryer house for more than 6 months were contaminated with aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), ochratoxin, and patulin with 24.48; 10.98; 57.18 and 16.92 of area max (106), respectively. Samples of broken green beans stored in contaminated warehouses were contaminated with patulin. However, all roasted bean and roasted bean samples that have been mashed do not contain aflatoxin B1, B2, or patulin. Targeted metabolomic using LC-HRMS profiling is a powerful tool for the rapid detection of mycotoxin in coffee bean. This method could be developed for quantitative analysis to provide accurate concentration.
