Published: December 2022

One of the efforts to stop the transmission of Covid-19 to health workers is using masks, face shields, protective gowns, and gloves. PPE (Personal Protective Equipment) is vital to reduce the risks of contracting Covid-19. However, using complete PPE will significantly disrupt the process and way of working, especially when the availability of PPE is increasingly tricky during a pandemic. This study aimed to determine the factors that influence the use of personal protective equipment during the pandemic by medical record officer. The research method used was a quantitative observational analytic study using a cross-sectional design. The sampling technique used a total sampling of 56 medical record officers in Kuningan, Indonesia. Data were obtained through interviews and observations. The study results of the factors that influence the use of personal protective equipment during a medical record officer's pandemic are knowledge of the use of PPE, attitudes and use of PPE, and availability of PPE with use. The information obtained in this study is that more and more medical record officers in hospitals are significantly at risk of Covid-19 transmission. Therefore medical record officers are expected to better protect themselves by using complete PPE when dealing with patients.
A Study of Ice Class Rules for Propellers
Authors: Noble Peter G. , Bulat Vanja 
Published: December 2022

A study has been carried out of existing classification society and government regulatory body rules for propeller 'strength of ice class ships.
The problem of propeller/ice interaction has been studied from an analytical standpoint, and full scale ice load data obtained from the propulsion shafts of Arctic icebreakers have been reviewed. Using these data and the framework of existing regulations and design methods for ice-worthy propellers, a number of conclusions on the static and dynamic strength requirements for such systems have been reached.
The main conclusions of the study are that present regulations, while they may be sufficient for non-Arctic ice going ships, are not adequate for ships sailing in Arctic waters where propeller ice encounters are much more frequent and severe, and that using an 11ice torque factor" is not the most rational approach. Recommendations on design procedures are made.

Authors: Boswell Robert J. , Jessup Stuart D. , Kim Ki-Han 
Published: December 2022

Periodic single-blade loads were measured on model propellers in inclined flow and in a single-cycle circumferentially non-uniform longitudinal velocity field. The experimental results were correlated with predictions by the following methods:
1. A quasi-steady procedure developed by McCarthy at David W. Taylor Naval Ship Research and' Development Center (DTNSRDC)
2. An unsteady lifting surface theory developed by Tsakonas and his colleagues at Davidson Laboratory,
3 An unsteady lifting Surface theory developed by Kerwin and Lee. at MIT,
4. A refinement by Kerwin to the method of Kerwin and Lee to consider the inclination of the propeller slipstream.
In inclined flow, all four of the calculation methods evaluated consistently underprediCted1 the experimental values of the periodic single-blade loads. The method of Kerwin, which considers the inclination of the slipstream relative to the propeller axis, produced the best correlation· with experimental values. These correlations show that the inclination of the propeller slipstream relative to the propeller axis significantly influence the periodic single-blade loads. The importance of this inclination· increases with increasing ,time-average loading.
Hacia una poética crítica del gesto compasivo. Poemas en la encrucijada entre los estudios subalternos y afectivos
Authors: Picornell Mercè 
Published: December 2022

En este artículo me propongo aportar algunas herramientas para la consideración de la encrucijada entre estudios afectivos y estudios subalternos. Se analizará cómo la compasión es un lugar crítico relevante para interrogarse sobre la complejidad de este cruce, y que ha motivado tanto defensas sobre su vinculación con la justicia como objeciones que denuncian la jerarquía implícita en lo compasivo. Cuestiones como la distancia social, el compromiso intelectual o los vínculos entre emoción y poder son importantes tanto en la discusión de los estudios subalternos y afectivos como en el debate en torno a la compasión, que ha sido especialmente vivo en el contexto político estadounidense. Para concretar el análisis, se postula que la poesía contemporánea es un género adecuado para motivar una reflexión sobre la tensión entre emoción individual y compromiso público que el debate sobre lo compasivo promueve. El artículo se cierra con una lectura de Resistir a les palpentes (2020), un poemario de Tony García del Río, cuyos textos proponen un gesto sensible hacia el otro que desafía las formulaciones habituales de lo compasivo.

Background:Over a life course, human adaptive immunity to antigenically mutable pathogens exhibits competitive and facilitative interactions. We hypothesize that such interactions may lead to cyclic dynamics in immune responses over a lifetime.Methods:To investigate the cyclic behavior, we analyzed hemagglutination inhibition titers against 21 historical influenza A(H3N2) strains spanning 47 years from a cohort in Guangzhou, China, and applied Fourier spectrum analysis. To investigate possible biological mechanisms, we simulated individual antibody profiles encompassing known feedbacks and interactions due to generally recognized immunological mechanisms.Results:We demonstrated a long-term periodicity (about 24 years) in individual antibody responses. The reported cycles were robust to analytic and sampling approaches. Simulations suggested that individual-level cross-reaction between antigenically similar strains likely explains the reported cycle. We showed that the reported cycles are predictable at both individual and birth cohort level and that cohorts show a diversity of phases of these cycles. Phase of cycle was associated with the risk of seroconversion to circulating strains, after accounting for age and pre-existing titers of the circulating strains.Conclusions:Our findings reveal the existence of long-term periodicities in individual antibody responses to A(H3N2). We hypothesize that these cycles are driven by preexisting antibody responses blunting responses to antigenically similar pathogens (by preventing infection and/or robust antibody responses upon infection), leading to reductions in antigen-specific responses over time until individual’s increasing risk leads to an infection with an antigenically distant enough virus to generate a robust immune response. These findings could help disentangle cohort effects from individual-level exposure histories, improve our understanding of observed heterogeneous antibody responses to immunizations, and inform targeted vaccine strategy.Funding:This study was supported by grants from the NIH R56AG048075 (DATC, JL), NIH R01AI114703 (DATC, BY), the Wellcome Trust 200861/Z/16/Z (SR), and 200187/Z/15/Z (SR).

Published: December 2022

Background
Yak cows produce higher quality milk with higher concentrations of milk fat than dairy cows. Recently, studies have found the yak milk yield and milk fat percentage have decreased significantly over the past decade, highlighting the urgency for yak milk improvement. Therefore, we aimed to analyze how the gut microbiome impacts milk fat synthesis in Zhongdian yak cows.

Methods
We collected milk samples from Zhongdian yak cows and analyzed the milk fat percentage, selecting five Zhongdian yak cows with a very high milk fat percentage (>7%, 8.70 ± 1.89%, H group) and five Zhongdian yak cows with a very low milk fat percentage (<5%, 4.12 ± 0.43%, L group), and then obtained gut samples of these ten Zhongdian yak cows through rectal palpation. Gut metagenomics, metabolomics, and conjoint metagenomics and metabolomics analyses were performed on these samples, identifying taxonomic changes, functional changes, and changes in gut microbes-metabolite interactions within the milk fat synthesis-associated Zhongdian yak cows gut microbiome, to identify potential regulatory mechanisms of milk fat at the gut microbiome level in Zhongdian yak cows.

Results
The metagenomics analysis revealed Firmicutes and Proteobacteria were significantly more abundant in the gut of the high-milk fat Zhongdian yak cows. These bacteria are involved in the biosynthesis of unsaturated fatty acids and amino acids, leading to greater efficiency in converting energy to milk fat. The metabolomics analysis showed that the elevated gut metabolites in high milk fat percentage Zhongdian yak cows were mainly enriched in lipid and amino acid metabolism. Using a combined metagenomic and metabolomics analysis, positive correlations between Firmicutes (Desulfocucumis, Anaerotignum, Dolosiccus) and myristic acid, and Proteobacteria (Catenovulum, Comamonas, Rubrivivax, Marivita, Succinimouas) and choline were found in the gut of Zhongdian yak cows. These interactions may be the main contributors to methanogen inhibition, producing less methane leading to higher-efficient milk fat production.

Conclusions
A study of the gut microbe, gut metabolites, and milk fat percentage of Zhongdian yak cows revealed that the variations in milk fat percentage between yak cows may be caused by the gut microbes and their metabolites, especially Firmicutes-myristic acid and Proteobacteria-choline interactions, which are important to milk fat synthesis. Our study provides new insights into the functional roles of the gut microbiome in producing small molecule metabolites and contributing to milk performance traits in yak cows.

Aim: Yeasts are present as natural microflora on surface of fruits and vegetables that have eminent importance from deputing as biocontrol agents to reduce pathogens of fruits and vegetables to the health benefits of humans.
Materials and Methods: Yeasts were isolated using standard plate count technique. Colony morphology of yeasts isolates were characterized under microscope for their cell shapes and sizes. Biochemical characteristics of yeasts were characterized for presence of effervescence in catalase test and production of acid and gas in Yeast Extact Peptone Dextrose (YEPD) broth. Utilization of carbon sources were evaluated by inoculating yeast isolates in YEPD broth with specific carbon source and phenol indicator. Ethanol tolerance were evaluated inoculating yeast isolates in YEPDA broth having different concentrations of ethanol viz., 0%, 5.0%, 10.0%, 12.5% and 15.0%.
Results: Population of yeast in jackfruit juices varied from 20.5 x 103 to. 70.0 x 103cfu per millilitre. Population of yeast varied in beet root juices from 34.5 x 103 to 43.0 x 103 cfu per millilitre. Juice of Chandra variety of jackfruit recorded the highest yeast population (7.0 x 104) when compared to others. Juice of Detroit red dark variety of beetroot (4.3 x 104) recorded highest yeast population (4.3 x 104) when compared to others. Yeasts were also isolated from different fruits of which BRTY-I, JKFY-I, POMY-I, WATY-I, APLY-I, MUSKY-I and PINY-I were able to grow in jackfruit and beet root juices. The colonies of yeast varied from white to cream and few were pink. The cell shape varied from oval to ellipsoidal. All the yeast isolates were catalase positive. Most of the yeast isolates produced acid and gas. Yeast isolates were able to utilize glucose, galactose and sucrose. None of the yeast were able to utilize lactose. The highest ethanol tolerant yeasts were JCVY-I, JSVY-III, BDVY-I, PGY, Saccharomyces boulardii and Saccharomyces cerevisiae var. ellipsoideus NCIM 3207.

Abstract

Objectives
Multicomponent interventions reduce falls among community-dwelling older adults. However, whether this strategy helps reduce occupational falls among older workers is unclear. This pilot trial tested the safety, adherence, and potential effectiveness of a multicomponent intervention for older workers.

Methods
An assessor-blind, parallel-designed randomized controlled trial was conducted in five public employment agencies for seniors in Saitama, Japan. In total, 69 older adults who worked ≥4 days/month were randomly assigned to the intervention (n = 35) or control (n = 34) groups. The intervention group was provided a multicomponent intervention consisting of exercise, nutrition, and psychosocial programs once a week for 8 weeks. Safety was evaluated for all adverse events reported by participants. Adherence was assessed by rates for withdrawal/dropout, exercise practice, and nutritional diary completion. The primary outcome was a change in functional strength related to occupational falls. Secondary outcomes included changes in agility, balance, executive function, visuospatial ability, exercise self-efficiency, dietary variety, social network, and functional capacity.

Results
No adverse events were reported by participants. The median withdrawal/dropout, exercise practice, and nutritional diary completion rates were 0%, 80.4%–93.7%, and 100%, respectively. In the adjusted general linear model, the intervention group showed a non-significant but clinically important improvement in functional strength (P value: .081, Cohen's d: 0.57) and significant improvements in agility, balance, and dietary variety compared to the control group.

Conclusions
A multicomponent intervention for older workers would be a safe, acceptable, and effective strategy for improving risk factors for occupational falls.

Published: December 2022

AbstractBackgroundIn external beam radiotherapy, a prediction model is required to compensate for the temporal system latency that affects the accuracy of radiation dose delivery. This study focused on a thorough comparison of seven deep artificial neural networks to propose an accurate and reliable prediction model.MethodsSeven deep predictor models are trained and tested with 800 breathing signals. In this regard, a nonsequential‐correlated hyperparameter optimization algorithm is developed to find the best configuration of parameters for all models. The root mean square error (RMSE), mean absolute error, normalized RMSE, and statistical F‐test are also used to evaluate network performance.ResultsOverall, tuning the hyperparameters results in a 25%–30% improvement for all models compared to previous studies. The comparison between all models also shows that the gated recurrent unit (GRU) with RMSE = 0.108 ± 0.068 mm predicts respiratory signals with higher accuracy and better performance.ConclusionOverall, tuning the hyperparameters in the GRU model demonstrates a better result than the hybrid predictor model used in the CyberKnife VSI system to compensate for the 115 ms system latency. Additionally, it is demonstrated that the tuned parameters have a significant impact on the prediction accuracy of each model.

AbstractBioelectronics hold the key for understanding and treating disease. However, achieving stable, long‐term interfaces between electronics and the body remains a challenge. Implantation of a bioelectronic device typically initiates a foreign body response, which can limit long‐term recording and stimulation efficacy. Techniques from regenerative medicine have shown a high propensity for promoting integration of implants with surrounding tissue, but these implants lack the capabilities for the sophisticated recording and actuation afforded by electronics. Combining these two fields can achieve the best of both worlds. Here, the construction of a hybrid implant system for creating long‐term interfaces with tissue is shown. Implants are created by combining a microelectrode array with a bioresorbable and remodellable gel. These implants are shown to produce a minimal foreign body response when placed into musculature, allowing one to record long‐term electromyographic signals with high spatial resolution. This device platform drives the possibility for a new generation of implantable electronics for long‐term interfacing.

AbstractInterest in defect engineering for lithium‐ion battery (LIB) materials is sparked by its ability to tailor electrical conductivity and introduce extra active sites for electrochemical reactions. However, harvesting excessive intrinsic defects in the bulk of the electrodes rather than near their surface remains a long‐standing challenge. Here, a versatile strategy of quenching is demonstrated, which is exercised in lithium titanate (Li4Ti5O12, LTO), a renowned anode for LIBs, to achieve off‐stoichiometry in the interior region. In situ synchrotron analysis and atomic‐resolution microscopy reveal the enriched oxygen vacancies and cation redistribution after ice‐water quenching, which can facilitate the native unextractable Li ions to participate in reversible cycling. The fabricated LTO anode delivers a sustained capacity of 202 mAh g−1 in the 1.0–2.5 V range with excellent rate capability and overcomes the poor cycling stability seen in conventional defective electrodes. The feasibility of tuning the degree of structural defectiveness via quenching agents is also proven, which can open up an intriguing avenue of research to harness the intrinsic defects for improving the energy density of rechargeable batteries.
Melt Electrowriting of Liquid Crystal Elastomer Scaffolds with Programmed Mechanical Response
Authors: Javadzadeh Mehrzad , del Barrio Jesús , Sánchez‐Somolinos Carlos 
Published: December 2022

AbstractRecently, significant advances have been achieved to precisely program the response of liquid crystal elastomers (LCEs) through extrusion‐based additive manufacturing techniques; however, important challenges remain, especially when well‐defined scaffolds based on ultrafine fibers are required. Here the melt electrowriting of reactive liquid crystalline inks, leading, after ultraviolet‐light‐induced crosslinking, to digitally positioned uniform LCE fibers with diameters ranging from hundreds of nanometers to tens of micrometers is presented, which is hardly accessible with conventional extrusion‐based printing techniques. The electrowriting process induces the preferential alignment of the mesogens parallel to the fiber's axis. Such an alignment, defined by the printing path, determines the mechanical response of the crosslinked material upon stimulation. This manufacturing platform allows the preparation of open square lattice scaffolds with ultrafine fibers (a few micrometers in diameter), periods as small as 90 µm, and well‐defined morphology. Additionally, the combination of accurate fiber stacking (up to 50 layers) and fiber fusion between layers leads to unprecedented microstructures composed of high‐aspect‐ratio LCE thin walls. The possibility of digitally controlling the printing of fibers allows the preparation complex fiber‐based scaffolds with programmed and reversible shape‐morphing, thus opening new avenues to prepare miniaturized actuators and smart structures for soft robotics and biomedical applications.

Abstract2D multiferroics with magnetoelectric coupling combine the magnetic order and electric polarization in a single phase, providing a cornerstone for constructing high‐density information storages and low‐energy‐consumption spintronic devices. The strong interactions between various order parameters are crucial for realizing such multifunctional applications, nevertheless, this criterion is rarely met in classical 2D materials at room‐temperature. Here an ingenious space‐confined chemical vapor deposition strategy is designed to synthesize atomically thin non‐layered ε‐Fe2O3 single crystals and disclose the room‐temperature long‐range ferrimagnetic order. Interestingly, the strong ferroelectricity and its switching behavior are unambiguously discovered in atomically thin ε‐Fe2O3, accompanied with an anomalous thickness‐dependent coercive voltage. More significantly, the robust room‐temperature magnetoelectric coupling is uncovered by controlling the magnetism with electric field and verifies the multiferroic feature of atomically thin ε‐Fe2O3. This work not only represents a substantial leap in terms of the controllable synthesis of 2D multiferroics with robust magnetoelectric coupling, but also provides a crucial step toward the practical applications in low‐energy‐consumption electric‐writing/magnetic‐reading devices.
