Effective process control requires good cognitive human factors to achieve safety and performance goals. These human factors include situation awareness tools, good communication and teamwork skills, and effective policies and procedures.

There is growing interest in saliva microRNAs (miRNAs) as non-invasive biomarkers for human disease. Such an approach requires understanding how differences in experimental design affect miRNA expression. Variations in technical methodologies, coupled with inter-individual variability may reduce study reproducibility and generalizability. Another barrier facing salivary miRNA biomarker research is a lack of recognized “control miRNAs”. In one of the largest studies of human salivary miRNA to date (922 healthy individuals), we utilized 1225 saliva samples to quantify variability in miRNA expres

The weak magneto-optical (MO) signal of traditional MO materials is indeed an important issue for their further practical applications. Although many strategies have been proposed to improve the MO effect, hybridization with noble metal nanostructures is a promising route in recent years due to the high localized-surface plasmon resonances (LSPR) effect. A new magneto-optical surface plasmon resonance (MOSPR) structure hybrid with Au bowtie arrays is proposed to increase the measuring range of the polar magneto-optical Kerr effect (PMOKE) and the quality factor through the LSPR effect.

Abstract:

The design of bowtie antennas for carbon nanotube (CNT) photodetectors has been investigated. CNT photodetectors have shown outstanding performance by using CNT as sensing element. However, detection wavelength is much larger than the diameter of the CNT, resulting in small fill factor. Bowtie antenna can confine light into a subwavelength volume based on plasmonic resonance, thus integrating a bowtie antenna to CNT photodetectors can highly improve photoresponse of the detectors. The electric field enhancement of bowtie antennas was calculated using the device geometry by considering fabricat

It is proposed that the plasmonic optical trapping force around a quantum dot exhibits symmetry-broken characteristics and becomes increasingly asymmetrical with increasing applied laser electric field.

When A is noncommutative prime, then $A\bowtie I$ is noncommutative semiprime (but not prime except if I = (0)). In this case, we prove that any map of $A\bowtie I$ which is both Jordan and Jordan triple derivation is a derivation.

The well-known BowTie is the model that turns out to be singularly well suited as a digital twin from the risk perspective as it maps out the risk space together with real-life controls. However, for a BowTie to be a high-fidelity digital twin of a real system, the rules and processes for designing

Background—Bowtie analysis is a broadly used tool in risk management to identify root causes and consequences of hazards and show barriers that can prevent or mitigate the events to happen.

High-Tc superconducting (HTS) Josephson junction (JJ) mixers are performing candidates for THz receiver frontends because of the advantages of excellent sensitivity, wide bandwidth, high harmonic number and low LO power requirement.

An 8-cycle is said to be squashed if we identify a pair of opposite vertices and name one of them with the other (and thereby turning the 8-cycle into a pair of 4-cycles with exactly one vertex in common).

The object of this paper is the construction, for every n > 8, of a maximum packing of Kn with 8-cycles which can be squashed in a maximum packing of Kn with 4-cycles.

Abstract:

The resonance performance analysis of graphene antennas is a challenging problem for full-wave electromagnetic simulators due to the trade-off between the computer resource and the accuracy of results. In this paper, an equivalent circuit model is presented to provide a concise and fast way to analyze the graphene-based THz bowtie antenna. Based on the simulated results of the frequency responses of the antenna, a suitable equivalent circuit of Resistor-Inductor-Capacitor (RLC) series is proposed to describe the antenna. Then the RLC parameters are extracted by considering the graphene bowtie

Abstract:

Primary reformer adalah komponen utama dalam unit reforming yang dapat mengubah gas alam menjadi gas sintetis melalui proses reformasi uap. Reformer ini beroperasi pada kondisi ekstrem, yang melibatkan tekanan tinggi dan suhu tinggi sehingga potensi risiko sangat signifikan. Salah satu metode yang semakin popular adalah Bowtie Diagram menawarkan pendekatan yang sistematis untuk memetakan risiko. Metode penelitian yang digunakan pada penelitian ini dengan bowtie diagram selain menggunakan metode analisis Hazard Identification Risk Assessment and Determining Control (HIRADC) disusun pula metode

Permasalahan manajemen risiko Keselamatan dan Kesehatan Kerja (K3) di laboratorium kimia, di mana paparan bahaya seperti iritasi kimia, sengatan listrik, ledakan, dan jatuh dari ketinggian secara kolektif menyumbang insiden kecelakaan berdasarkan data historis dan observasi lapangan. Kasus-kasus ini dominan terjadi akibat prosedur kerja yang tidak sesuai standar, pengelolaan limbah kimia yang tidak optimal, serta kurangnya kompetensi operator dalam menerapkan protokol keselamatan. Kebaruan penelitian terletak pada penerapan metode Bowtie secara komprehensif untuk memetakan penyebab, konsekuens

Abstract:

A streaming television usually broadcasted through internet and can be watched on computer or mobile phone. However it can also be seen through television using video sender as the transmitter. To transmit it, of course, a suitable antenna is needed, in this case a bowtie antenna is selected. This research describe the design of a bowtie antenna that will be used as a transmitter antenna on a video sender. This bowtie antenna is designed by using an aluminum plate works on frequency of 655 MHz and has a return loss value of -21.127 dB, VSWR 1.192, 5.11 dB gain and bi-directional radiation patt

Abstract:

Determining the effectiveness of a management system to enable fisheries to harvest sustainably is a key challenge. To fully assess the likelihood that a fishery management system will not achieve its sustainability objectives, the assessment needs to include the whole pathway that leads to the consequences for management objectives. A crucial aspect of the pathway is the inclusion of management controls. Effectiveness of these management controls determines whether the effects of human pressures on ecological components and their impacts are reduced to a level that will not impede management

Abstract Current research has demonstrated the importance of identification of antigen-specific T cells for use in adoptive cell therapy to treat cancer. By identifying rare T cells, we may be able to determine highly effective reagents for tumor regression. A major problem in identifying TCR for clinical applications has been development of high-throughput methods for obtaining CDR3 sequence information from TCRαβ pairs from individual cells. To this end, we have developed novel DNA origami nanostructures with “bowtie”-barcoded capture probes to simultaneously capture human TCRαβ mRNA from si

This paper aims to investigate the issues related to safety in confined space at the sewerage treatment plant construction project in the Hulu Langat district and to provide a solution by proposing a substantial approach to mitigating risk during confined space entry due to an ineffective risk assessment and poor compliance by project management. The methods used were site visit observation and survey, followed by an analysis of the selected risk assessment method. The site visit to the sewerage treatment plant project investigated the compliance of confined space risk assessment documents to
