Published: September 2022

Abstract
Cronobacter spp is an opportunistic pathogen that can cause severe neonatal infections, including septicemia, meningitis, and necrotizing enterocolitis. Over 90% of these infections outbreaks are associated with the increased consumption of powdered infant formula (PIF). We report the case of a male neonate born at term with adequate weight for gestational age, fed by breast milk and PIF. He was admitted to the ICU at 22 days old due to fever, irritability, impaired consciousness, and food intolerance. Investigation revealed an extensive abscess in the right frontoparietal region, that was surgically drained. The culture of the purulent material showed the growth of Cronobacter spp. Guided antibiotic was kept for 21 days. The patient presented a good clinical outcome, without neurological deficits. The microbiological powdered formula contamination by Enterobacter sakazakii (Cronobacter spp) can lead to a higher risk of severe infections in infants. Children may present sepsis, sensory alteration, and refractory seizures. An early brain image should be considered for symptomatic infants. The mortality rate ranges from 40 to 80%, and 74% of survivors have an adverse neurological outcome. From 1997–2013, there were reports of 6 outbreaks of E. sakazakii disease in Brazil. According to the World Health Organization (WHO), this disease is undernotified, and active foodborne surveillance systems are less than ideal. To better address this problem, in some countries, the notification is mandatory, and the adoption of stricter sanitary measures by regulatory agencies are proposed.

Published: September 2022

AbstractThere are several complications associated with immunization with the pentavalent vaccine. Most of them are mild reactions, of spontaneous resolution; however, though rare, serious and potentially-fatal adverse effects can occur. We report a case of acute intracranial hypertension syndrome in an infant with a previously-unknown suprasellar arachnoid cyst who developed acute obstructive hydrocephalus after immunization with the pentavalent vaccine. He underwent neuroendoscopic treatment, showing complete resolution of the condition. The present article aims to compare the activation of the immune system by the pertussis component of the vaccine and the mechanisms that hypothetically potentiated the pathological decompensation.
Demonstration of static atomic gravimetry using Kalman filter
Authors: Jiang Bo-Nan 
Published: September 2022

The measurement precision of the static atomic gravimetry is limited by white Gaussian noise in short term, which costs previous works an inevitable integration to reach the precision demanded. Here, we propose a statistical model based on the quantum projection noise and apply the associated Kalman filter with the waveform estimation in static atomic gravimetry. With the white Gaussian noise significantly removed by the Kalman-filter formalism, the measurement noise of the gravimetry is reshaped in short term and shows τ1/2 feature that corresponds to a random walk. During 200 h of static measurement of gravity, the atomic gravimeter using Kalman filter demonstrates a sensitivity as good as 0.6 nms2/s and highlights a precision of 1.7 nms2 at the measuring time of a single sample. The measurement noise achieved is also lower than the quantum projection limit below ∼30 s.

Abstract
Effective evaluation of taste sensation can be achieved by analyzing electronic tongue (e-tongue) data. Research on evaluation of the taste sensation of an e-tongue by nerve conduction mechanisms is limited, which obviously affects performance evaluation of e-tongues. Therefore, in this paper, a method for evaluating the taste sensation of an e-tongue based on human taste conduction mechanisms, the computational model of taste pathways (CMTP), is proposed. However, the limited physiological basis of the CMTP parameters influences the evaluation results. To achieve excellent evaluation performance, a parameter optimization algorithm with Hebbian and habituation learning rules is used to optimize the CMTP parameters. The effectiveness of the optimized results is demonstrated by improvement in the dynamic characteristics of the CMTP. Next, the optimized CMTP (OCMTP) is used for pattern recognition and sweetness evaluation of four taste substances. The results showed, first, that the dynamic characteristics (including 1/f characteristics and synchronization) of the OCMTP are improved, and the bionics of the OCMTP is enhanced. The optimized results are effective. Second, compared with the recognition results for the four taste substances by the unoptimized CMTP (UCMTP), signal preprocessing methods and multiclass classification models, the best classification accuracy (95.38%), the best kappa coefficient (93.83%) and the best F
1-score (96.10%) are achieved by the OCMTP. Finally, compared with the sweetness evaluation results of the UCMTP, signal preprocessing methods and multiple evaluation models, the best evaluation performance, including a root-mean-square error of 0.1643 and R
2 of 0.9785, is obtained using the OCMTP. In conclusion, effective evaluation of taste sensation can be achieved by the OCMTP and an e-tongue.
Effect of particle spin on trajectory deflection and gravitational lensing
Authors: Zhang Zhuoming , Fan Gaofeng , Jia Junji 
Published: September 2022

AbstractSpin of a test particle is a fundamental property that can affect its motion in a gravitational field. In this work we consider the effect of particle spin on its deflection angle and gravitational lensing in the equatorial plane of arbitrary stationary and axisymmetric spacetimes. To do this we developed a perturbative method that can be applied to spinning signals with arbitrary asymptotic velocity and takes into account the finite distance effect of the source and the observer. The deflection angle Δφand total travel time Δtare expressed as (quasi-)power series whose coefficients are polynomials of the asymptotic expansion coefficients of the metric functions. It is found that when the spin and orbital angular momenta are parallel (or antiparallel), the deflection angle is decreased (or increased). Apparent angles θ of the images in gravitational lensing and their time delays are also solved. In Kerr spacetime, spin affects the apparent angleθKin a way similar to its effect on ΔφK. The time delay between signals with opposite spins is found to be proportional to the signal spin at leading order. These time delays might be used to constrain the spin to mass ratio of neutrinos.

Abstract
The acting on the planing hull is the most complex hydrodynamics simulation. Therefore, an analysis was done to evaluate drag, lift force, and seakeeping in two degrees of freedom (2-DOF) which is heave and trim. It was fundamental aspects of the overall high-speed vessel. This article focused on the hydrodynamic performance of a complete interceptor configuration that could control the motion behavior of deep-V planing hull in calm water conditions. The benchmark study was undertaken by comparing numerical results with experimental study by Park at al. Models with and without interceptors had been analyzed by numerical simulation performed using Reynold Averaged Navier Stokes (RANS) to describe turbulence model with k epsilon based on computational fluid dynamic (CFD). In this study, the interceptor proper applies at a speed of less than Froude number 0.87. Interceptor reduce by 21% drag at Froude number 0.87 and also reduce by 16% trim and 6% heave at Froude number 0.58. Nevertheless, applied interceptor in high Froude number such as more than Froude number 1.16 caused interceptor lose effectiveness due to producing a decisive moment which made negative trim (bow-down) and increase total drag.

Published: September 2022

Abstract
The longitudinal structure is needed to hold the boat, especially in sagging and hogging conditions. Modifying a longitudinal system using laminating steel and fiber is required to increase strength and reduce weight. This study uses a 7.8 m ship modified from conventional to hybrid construction. The finite element method compared the conventional and hybrid ship structures under sagging and hogging conditions to evaluate ship strength. In sagging conditions, the maximum stress in conventional boats is 16.68 MPa, reduced up to 13.65 MPa in hybrid boats. In hogging condition indicate that conventional has maximum stress is 11.18, which is higher than in conventional structure, as much as 10.38 MPa. The keel stress distribution in a couple of conditions of sagging and hogging indicates that the hybrid structure has lower stress than conventional vessels. The simulation shows that a longitudinal hybrid frame makes the ship stiffer in sagging and hogging conditions. The weight of conventional and hybrid boats is similar and affordable to more developing hybrid ships.

Published: September 2022

Abstract
Utilization Mini LNG Carrier is an alternative solution to support the supply chain for the distribution of liquefied natural gas (LNG) to gas power plants, especially in Eastern Indonesia. Mini LNG carriers must have adequate seakeeping and manoeuvrability in carrying out their missions. The biggest challenge faced when manoeuvring in shallow water where the rotation of the propeller can produce high-velocity water flows that cause sedimentation on the seabed. The distance between the tip of the propeller to the seabed greatly determines the level of ease of erosion and sedimentation that can occur. This study aims to provide an alternative ships’ operational concept by mapping the suitability between the depth of the water and the rpm of the propeller that does not cause sedimentation on the seabed. This concept determines the velocity of the water flow at which sedimentation begins to occur as the propeller rpm threshold. The final result is a depth division map where the propeller can be used at maximum rpm, the propeller is used with a limited rpm and the depth at which the propeller is not recommended to be used.

Published: September 2022

Abstract
The high number of fishing vessels accidents in the Java Sea is due to the large number of fishing vessels that do not have safety support equipment in sailing, such as SART (Search and Rescue Transponder). So fatalities occur because it is difficult to find the location of fishers when an accident occurs. Also, the high cost of SART equipment on the market makes fishers unable to afford it. Research related to Mini SART-DMOM (Search and Rescue Transponder-DMOM) is an innovation tool with a working system almost the same as SART on the market, and this equipment has a lower price compared to SART sold on the market. In assembling the prototype, the main components used are GPS Neo 6m, Arduino Uno, LoRa and Wemos (ESP 8266). The prototype assembly is divided into Mini SART-DMOM and Mini SARR-DMOM (Search and Rescue Receiver-DMOM). In the prototype test that was carried out, it ran smoothly where the Mini SART-DMOM could get location via GPS. Lora sent the location data from the LoRa Transponder to the LoRa Receiver. The data received by the Receiver was sent by the wifi Board (Wemos ESP 8266) to be monitored live remotely via Web Blynk. However, in this trial, the maximum recorded range was required to be improved.

Abstract
One of the renewable energy sources is ocean currents which can be extracted with the Darrieus vertical axis hydrokinetic turbine (VAHT). This research aims to analyze the deformation and structural stresses that occur in the Darrieus VAHT support frame due to the loads. In the VAHT installation, it is necessary to have a support structure in the form of a solid frame, so that the turbine remains in a stable condition when operating. The VAHT frame must be able to withstand the load from a rotating turbine and have a small drag force. This study conducted a numerical simulation using the finite element analysis method. The effect of the cross-sectional shape of the structural beams on the drag due to flow was also investigated. The result is the frame designed with the ASTM A36 Grade B pipe structure has maximum stress of 63,116 MPa and it is relatively smaller and remains within the safe limits of the material. In addition, based on CFD simulation, the drag caused by the flow across the structure with this design is also smaller. Therefore, this study can be used as a consideration in making decisions to design the Darrieus VAHT frame.

Abstract
The use of engineered cells, tissues, and organs has the opportunity to change the way injuries and diseases are treated. Commercialization of these groundbreaking technologies has been limited in part by the complex and costly nature of their manufacture. Process-related variability and even small changes in the manufacturing process of a living product will impact its quality. Without real-time integrated detection, the magnitude and mechanism of that impact are largely unknown. Real-time and non-destructive sensor technologies are key for in-process insight and ensuring a consistent product throughout commercial scale-up and/or scale-out. The application of a measurement technology into a manufacturing process requires cell and tissue developers to understand the best way to apply a sensor to their process, and for sensor manufacturers to understand the design requirements and end-user needs. Furthermore, sensors to monitor component cells’ health and phenotype need to be compatible with novel integrated and automated manufacturing equipment. This review summarizes commercially relevant sensor technologies that can detect meaningful quality attributes during the manufacturing of regenerative medicine products, the gaps within each technology, and sensor considerations for manufacturing.
Failure assessment of 3D woven composites under compression after low-velocity impact
Authors: Sun Jin , Dai Yunfeng , Huang Linhai , Zhao Junhua 
Published: September 2022

Abstract
The failure mechanism of 3D woven composites subjected to compression loading along principal/off-axis direction after low-velocity impact (LVI) was assessed by experimental and numerical methods. The low-velocity impacts under 26.8 J and 80 J energies were applied to the specimens with off-axis angles of 0° and 45°. It can be observed that the impact damages are direction-dependent, which is determined by the weft and warp orientations. By performing the compression-after-impact (CAI) tests, it is found that the CAI strength along principal direction is more sensitive to the low-velocity impact than that along off-axis direction. A finite element dynamic analytical method was established, considering four off-axis angles (0°, 30°, 45° and 60°). The results show that the extension direction of the impact damage changes regularly with the off-axis angle. During the compression, the small off-axis angle can make the specimen prone to produce a sudden crushing failure determined by the fiber failure due to the high axial stress. As the off-axis angle increases, the matrix damage gradually holds the dominant position due to the growing shear effect, which makes the specimen produce a ductile failure governed by the accumulated matrix failure.
