The bivoltine strain of the domestic silkworm, Bombyx mori, has two generations per year. It shows a facultative diapause phenotype determined by environmental conditions, including photoperiod and temperature, and nutrient conditions during embryonic and larval development of the mother. However, it remains unclear how the environmental signals received during development are selectively utilized as cues to determine alternative diapause phenotypes. We performed a comparative analysis between the Kosetsu strain of B. mori and a Japanese population of the wild mulberry silkworm B. mandarina concerning the hierarchical molecular mechanisms in diapause induction. Our results showed that for the Kosetsu, temperature signals during the mother’s embryonic development predominantly affected diapause determination through the thermosensitive transient receptor potential ankyrin 1 (TRPA1) and diapause hormone (DH) signaling pathways. However, embryonic diapause in B. mandarina was photoperiod-dependent, although the DH signaling pathway and thermal sensitivity of TRPA1 were conserved within both species. Based on these findings, we hypothesize that TRPA1-activated signals are strongly linked to the signaling pathway participating in diapause induction in Kosetsu to selectively utilize the temperature information as the cue because temperature-dependent induction was replaced by photoperiodic induction in the TRPA1 knockout mutant.

This study investigated incidence and risk factors for venous thromboembolism (VTE) in patients with cervical cancer. We selected 49,514 patients newly diagnosed with cervical cancer from the Korean Health Insurance Review and Assessment Service databases. During the total follow-up period and first 6 months after initiation of primary treatments, incidence of VTE, and association of risk factors with VTE occurrence were evaluated according to primary treatments or no treatment, surgery, radiotherapy, and chemotherapy. VTE occurred in 1.15% of patients with cervical cancer. Regardless of the period after initiation of primary treatments, and of VTE, the incidence of thromboembolism was highest in chemotherapy. During the first 12 months, monthly incidence of VTE was highest in chemotherapy and decreased with time in all primary treatments. Compared with no treatment, VTE risk significantly increased for all primary treatments (surgery: HR 1.492; 95% CI 1.186–1.877) (radiotherapy: HR 2.275; 95% CI 1.813–2.855) (chemotherapy: HR 4.378; 95% CI 3.095–6.193) and for chemotherapy during the first 6 months (HR 3.394; 95% CI 2.062–5.588). In this cohort study, incidence and risk of VTE in patients with cervical cancer were the highest when chemotherapy was the primary cancer treatment, and incidence of VTE decreased with time.

Published: April 2021

The hunt for useful sepsis biomarkers is ongoing. Macrophage migration inhibitory factor (MIF) was implicated as a biomarker in sepsis, but its diagnostic and prognostic value has remained unclear in human studies. Here, we aimed at clarifying the value of MIF as a sepsis biomarker with the meta-analysis of clinical trials. PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases were searched until December 2019. From the included studies, blood MIF levels and indicators of disease severity were extracted in septic and control patient groups. Twenty-one eligible studies were identified, including data from 1876 subjects (of which 1206 had sepsis). In the septic patients, blood MIF levels were significantly higher than in healthy controls with a standardized mean difference (SMD) of 1.47 (95% confidence interval, CI: 0.96–1.97; p < 0.001) and also higher than in patient groups with nonseptic systemic inflammation (SMD = 0.94; CI: 0.51–1.38; p < 0.001). Markedly greater elevation in blood MIF level was found in the more severe forms of sepsis and in nonsurvivors than in less severe forms and in survivors with SMDs of 0.84 (CI: 0.45–1.24) and 0.75 (CI: 0.40–1.11), respectively (p < 0.001 for both). In conclusion, blood MIF level is more elevated in systemic inflammation caused by infection (i.e., sepsis) compared to noninfectious causes. In more severe forms of sepsis, including fatal outcome, MIF levels are higher than in less severe forms. These results suggest that MIF can be a valuable diagnostic and prognostic biomarker in sepsis given that well-designed clinical trials validate our findings.

The objective of the study was to identify distinct patterns in inflammatory immune responses of COVID-19 patients and to investigate their association with clinical course and outcome. Data from hospitalized COVID-19 patients were retrieved from electronic medical record. Supervised k-means clustering of serial C-reactive protein levels (CRP), absolute neutrophil counts (ANC), and absolute lymphocyte counts (ALC) was used to assign immune responses to one of three groups. Then, relationships between patterns of inflammatory responses and clinical course and outcome of COVID-19 were assessed in a discovery and validation cohort. Unbiased clustering analysis grouped 105 patients of a discovery cohort into three distinct clusters. Cluster 1 (hyper-inflammatory immune response) was characterized by high CRP levels, high ANC, and low ALC, whereas Cluster 3 (hypo-inflammatory immune response) was associated with low CRP levels and normal ANC and ALC. Cluster 2 showed an intermediate pattern. All patients in Cluster 1 required oxygen support whilst 61% patients in Cluster 2 and no patient in Cluster 3 required supplementary oxygen. Two (13.3%) patients in Cluster 1 died, whereas no patient in Clusters 2 and 3 died. The results were confirmed in an independent validation cohort of 116 patients. We identified three different patterns of inflammatory immune response to COVID-19. Hyper-inflammatory immune responses with elevated CRP, neutrophilia, and lymphopenia are associated with a severe disease and a worse outcome. Therefore, targeting the hyper-inflammatory response might improve the clinical outcome of COVID-19.

Context. Centaurs go around the Sun between the orbits of Jupiter and Neptune. Only a fraction of the known centaurs have been found to display comet-like features. Comet 29P/Schwassmann-Wachmann 1 is the most remarkable active centaur. It orbits the Sun just beyond Jupiter in a nearly circular path. Only a handful of known objects follow similar trajectories.

Aims. We present photometric observations of 2020 MK4, a recently found centaur with an orbit not too different from that of 29P, and we perform a preliminary exploration of its dynamical evolution.

Methods. We analyzed broadband Cousins R and Sloan g′, r′, and i′ images of 2020 MK4 acquired with the Jacobus Kapteyn Telescope and the IAC80 telescope to search for cometary-like activity and to derive its surface colors and size. Its orbital evolution was studied using direct N-body simulations.

Results. Centaur 2020 MK4 is neutral-gray in color and has a faint, compact cometary-like coma. The values of its color indexes, (g′− r′) = 0.42 ± 0.04 and (r′− i′) = 0.17 ± 0.04, are similar to the solar ones. A lower limit for the absolute magnitude of the nucleus is Hg = 11.30 ± 0.03 mag which, for an albedo in the range of 0.1–0.04, gives an upper limit for its size in the interval (23,  37) km. Its orbital evolution is very chaotic and 2020 MK4 may be ejected from the Solar System during the next 200 kyr. Comet 29P experienced relatively close flybys with 2020 MK4 in the past, sometimes when they were temporary Jovian satellites.

Conclusions. Based on the analysis of visible CCD images of 2020 MK4, we confirm the presence of a coma of material around a central nucleus. Its surface colors place this centaur among the most extreme members of the gray group. Although the past, present, and future dynamical evolution of 2020 MK4 resembles that of 29P, more data are required to confirm or reject a possible connection between the two objects and perhaps others.

Heisenberg’s uncertainty principle associated with the Caputo fractional derivative
Authors: Lian Pan
Published: April 2021

In this paper, we establish the Heisenberg’s uncertainty inequality associated with the Caputo derivative of order q ∈ (1, ∞) in the generalized Bargmann–Fock space. We also determine exactly when the equality occurs in the uncertainty inequality. It is done by estimating the growth of the eigenvalues of the commutator [Dq,zq]. We prove that the sequence of eigenvalues of [Dq,zq] tends to ∞ when the fractional order q belongs to (1, ∞). However, the sequence converges to zero when q belongs to (0, 1), which shows different behavior. Hence, only a weak uncertainty inequality is obtained for the latter case.

Published: April 2021

The pinhole discharge using a novel electrode configuration was generated in various water–ethanol mixtures. Proton transfer reaction time-of-flight mass spectrometry was used for the diagnostics of stable discharge products. The sampling was realized by nitrogen constant flow over the liquid surface. Mostly, aliphatic hydrocarbons were detected. The number of products and their concentrations was observed in the dependence on the changing experimental conditions: alcohol concentration in the solution, the electrodes polarity, and the discharge duration. More compounds were detected with the increasing alcohol concentration and in the case of the positive polarity of the pinhole electrode.
Local decomposition of hybridization functions: Chemical insight into correlated molecular adsorbates
Authors: Bahlke Marc Philipp , Schneeberger Michaela , Herrmann Carmen
Published: April 2021

Hybridization functions are an established tool for investigating the coupling between a correlated subsystem (often a single transition metal atom) and its uncorrelated environment (the substrate and any ligands present). The hybridization function can provide valuable insight into why and how strong correlation features such as the Kondo effect can be chemically controlled in certain molecular adsorbates. To deepen this insight, we introduce a local decomposition of the hybridization function, based on a truncated cluster approach, enabling us to study individual effects on this function coming from specific parts of the systems (e.g., the surface, ligands, or parts of larger ligands). It is shown that a truncated-cluster approach can reproduce the Co 3d and Mn 3d hybridization functions from periodic boundary conditions in Co(CO)4/Cu(001) and MnPc/Ag(001) qualitatively well. By locally decomposing the hybridization functions, it is demonstrated at which energies the transition metal atoms are mainly hybridized with the substrate or with the ligand. For the Kondo-active 3dx2−y2 orbital in Co(CO)4/Cu(001), the hybridization function at the Fermi energy is substrate-dominated, so we can assign its enhancement compared with ligand-free Co to an indirect effect of ligand–substrate interactions. In MnPc/Ag(001), the same is true for the Kondo-active orbital, but for two other orbitals, there are both direct and indirect effects of the ligand, together resulting in such strong screening that their potential Kondo activity is suppressed. A local decomposition of hybridization functions could also be useful in other areas, such as analyzing the electrode self-energies in molecular junctions.
Novel double-band input coupler for gyroklystron and gyro-TWT
Authors: Wang Xiaoyan , Gao Dongping , Wang Yong , Zhang Fengzhen
Published: April 2021

A novel input coupler that can operate in two different frequency bands separately is proposed in this paper. The dual-band (X/Ku) signals are input by two rectangular waveguides, respectively, in particular, a Bragg reflector is inserted in one of the rectangular waveguides to avoid the electromagnetic backflow, and then the circular TE01/TE02 modes are excited in the cylindrical cavity by field diffraction through the coupling holes with the help of a coaxial cavity. The simulation results show that dual-band input couplers for both dual-band gyroklystron and gyrotron traveling wave tube obtain excellent performance, laying the foundation for the development of the dual-band gyro-amplifier.
Semi-analytical approach to retrieve the chromophoric dissolved organic matter absorption coefficient in non-turbid waters: preliminary application to Medium Resolution Imaging Spectrometer (MERIS) data
Authors: Shi Liangliang , Mao Zhihua , Zhang Yiwei
Published: April 2021

Based on the NASA Bio-Optical Marine Algorithm Dataset and in situ datasets collected from the East China Sea and Lake Qiandaohu, a novel approach was developed to analytically retrieve the absorption coefficient of chromophoric dissolved organic matter (aCDOM) in non-turbid waters. This approach comprised two parts: (1) a green–red band quasi-analytical algorithm, used to accurately derive the total absorption coefficient (a); and (2) the use of the retrievals from (1) are to semi-analytically retrieve aCDOM. This approach for partitioning aCDOM from a was based on the blue band line height at 443 nm, LH(443), which uses the summed absorption coefficients of phytoplankton and CDOM (aphc) at three characteristic wavelengths (412, 443 and 490 nm). This proposed algorithm was then tested and validated using the three datasets. The algorithm was found to perform reasonably well in retrieving aCDOM, with respective mean R2 and mean absolute percentage error (MAPE) values of 0.84 and 42.8%, compared with 0.64 and 72.9% for the empirical model and 0.40 and 66.2% for the extended quasi-analytical algorithm. Furthermore, the algorithm was able to retrieve aCDOM from Medium Resolution Imaging Spectrometer (MERIS) satellite data. One implication for the MERIS satellite data, which exhibit reasonable seasonal variability over the East China Sea, is that it can be used to explore biogeochemical effects on aquatic environments.
“More languages means more lights in your house”

Published: April 2021

French immersion programs throughout Canada have historically consisted of predominantly Anglophone populations pursuing bilingualism in the country’s two official languages, English and French. Nevertheless, recent developments in immigration and refugee resettlement have contributed to increasingly diverse student backgrounds nationwide (Statistics Canada, 2014). Researchers have explored the motivation for Allophone families to pursue FSL in Canada (Dagenais & Berron, 2001;Dagenais & Jacquet, 2000;Mady, 2010); the language proficiency of Allophone learners in FSL programs (Bérubé & Marinova-Todd, 2012;Carr, 2007;Mady, 2015); and the perspectives of FSL educators with respect to such learners (Mady, 2016;Mady & Masson, 2018;Roy, 2015). The present study draws from interview data to explore and compare the experiences and perspectives of seven Allophone parents and 43 FI educators in Saskatchewan. In the present article, we examine the perspectives of FI educators, the experiences of Allophone families, and the implications for immersion programs worldwide.
Plantago asiatica mosaic virus.
Authors: Hammond John
Published: April 2021

PlAMV was first described from the wild/weedy plant Plantago asiatica in the Russian Far East, and a Nandina mosaic isolate from cultivated Nandina domestica in the USA. PlAMV also naturally infects P. asiatica and Rehmannia glutinosa in the Republic of Korea, and N. domestica, Primula sieboldii, Lilium maximowiczii [Lilium leichtlinii var. maximowiczii] and Viola grypoceras in Japan. PlAMV has also been detected in commercially grown lilies in the Netherlands and elsewhere in Europe, Taiwan, the USA, Republic of Korea, Chile, China, New Zealand, India and Costa Rica. Japanese lily isolates are distinct from 'European-like' lily isolates, suggesting more than one introduction into lilies. Widespread occurrence in cultivated lilies is likely due to international distribution of infected bulbs. Losses of up to 80% have been reported in commercial greenhouse cut-flower production. PlAMV is able to spread readily through soil by uptake (and probably exudation) through the roots and is quite stable in contaminated planting media; no animal vector is known. PlAMV has a wide experimental host range.

Enhancing bush beans quality by applying Brown Algae (Ascophyllum sp) organic fertilizer
Authors: Rahayu S T , Rosliani R , Prathama M
Published: April 2021

Agriculture could be a solution for climate change by the widespread adoption of mitigation and adaptation actions. This happens with the help of best management practices such as organic fertilizer. The types of organic fertilizer will affect beans’ production and their quality characteristics, both physically and their nutrient content. The purpose of this study was to determine the effect of brown algae extracts as organic fertilizer applied to bush beans’ quality. The study was conducted in October 2017, on IVEGRI’s experimental field, Lembang, Indonesia about 1200 m above sea level. The experiment used 10 treatments and 3 replications), which were a variation dose of NPK and Liquid Organic Fertilizer (LOF). The physical and chemical characteristics of testing consisted of length, diameter, texture, water content, TSS, fibre, and vitamin C. The quantitative and qualitative analyses were used to determine the beans’ shelf life. Freshness test parameters were consisting of colour, texture, and appearance. Panelists provided a score of 1 (strongly like) to 5 (strongly dislike). Data were statistically analysed, followed by Tukey’s test (5%). The results showed that LOF with standard NPK dosage can increase vitamin C and fiber content of bush beans. Higher LOF dose usage can reduce the change rate of bush beans’ quality on shelf life. LOF from brown algae can reduce the chemical fertilizers used in the soil, so it will slowly create environmentally friendly vegetable production.

The use of agro-industrial wastewater can reduce environmental pollution and emissions of greenhouse gases into the atmosphere. One of them is by utilizing its acidity to dissolve phosphate rock (PR) which is used for P fertilizer. The purpose of this study was to determine the effect of agro-industrial wastewater and PR dosage for P availability and nutrient uptake by corn in ultisol soil. Split plot design was arranged with wastewater of tapioca and tofu as a main factor and dosage of PR after acidulation as a sub-plot. The results showed that wastewater had no effect on the available soil P, soil pH, N uptake, P uptake, and dry weights of corn plants, but PR dosage had a significant effect on available soil P, N uptake. There is an interaction between agro-industrial wastewater and PR dosage on the P availability. For acidulation with tofu wastewater, the PR dosage used is lower for the same soil P availability compared to tapioca wastewater. At high P dosages, acidulation PR with wastewater does not have a significant effect on soil P availability. Phosphorus and nitrogen uptake by corn increased with the application of 950 kg ha-1 acidulated PR.

The criticality of watersheds in Indonesia can trigger water scarcity and trigger environmental damage if it is not handled as early as possible especially during uncertain climate change conditions. The long-term impact of this condition, if it is not handled properly, is the damage to the ecosystem and habitat that can disrupt rainfall patterns. Regulatory issues, sub-optimal community empowerment, lack of public awareness, and the decrease of forest productivity are some of the causes. This study was aimed to find out the extent of environmental deterioration using indicators of Erosion Hazard (EH) and landslides and to formulate environmental management strategies as an effort to conserve the environment. Data collection for the first purpose was undertaken by observation, literature review, documentation, and for the second purpose was conducted by measurement, observation, and interview. The results of the analysis can be concluded that the level of environmental damage in the Widoro Sub-watershed was in the category of minor damage. It can be seen from EH and landslides that occurred in the Widoro Sub-watershed. The erosion and landslides that occurred were at a harmless level. The environmental management strategy included counseling and assistance activities, improvement of sanitation facilities, and monitoring and law enforcement on community activities related to land use, erosion, landslide and disaster, and also the selection of plants with high value economic.

A hydrogen reactor (HR) as co-combustion in a motor engine for reducing emission gas (EG) production has been successfully developed. The use of a motor engine in transportation does not only consume a lot of gasoline but also creates depletion in fossil fuel resources which subsequently increases the EG production. The increase of EG caused the highly hazardous to the environment such as global warming that affected climate change. To overcome this problem, we investigated the effect of HR on reducing EG production and consumption of gasoline for the motor engine. We manufactured the volume 34.5mL, 40.8mL, and 56.5mL of HR, then we used Halanaerobium hydrogeninformans water as hydrogen sources. For combustion, 1L Pertalite gasoline was applied in the engine motor. The experiment was conducted in variation temperature of HR (100 °C, 110 °C, 120 °C, 130 °C, 140 °C), and velocity of the motor engine (2000rpm, 3000rpm, 4000rpm). We examined that the EG production namely hydrocarbon, carbon dioxide, and carbon monoxide were decreasing with the use of HR compared without the HR for all experimental conditions. The result tests also show that the use of HR reduced the consumption of gasoline along with the combustion process. This study demonstrated that HR as co-combustion combined with Halanaerobium hydrogeninformans water has the potential for environmental protection such as climate change due to global EG production.

Construction activities gradually consume energy during their life cycle, namely material extrusion, transportation, production, assembly line, installation, demolition and disposal. This research aimed to identify research about energy such as embodied and operational energy. Operational energy is energy that is used during building life cycle to decrease global warming effect. This research used a qualitative method to identify and review some literature related to decreased energy construction. This study showed that 98% of researchers focus on energy efficiency in the design, construction and operational stages. Only 2% were investigating at the initiation stage. Some recommendations can be drawn suggesting that energy reduction is possible by applying optimization strategy to all project life cycle (PLC). Initiation and design phase are indirect energy optimization phase through policies and design buildings, which significantly impact energy decrease for further phases. In contrast, construction and operations phase is direct energy optimization phase through energy efficiency on each activity.

The development of oil palm plantations on peatlands leads to the release of greenhouse gases (GHG) into the atmosphere. Soil amelioration can improve the fertility of peat soil because consists of polyvalent cations that overcome the negative effect of high-level organic acid as well as reduce GHG emissions. This study aimed to observe the effectiveness of soil amelioration for reducing carbon dioxide (CO2) emission from oil palm plantations on peat soil. The study was carried out on smallholder oil palm at Kumpeh, Muara Jambi District, Jambi Province. The study was arranged with six treatments and four replications of a Randomized Completely Block Design (RCBD). The treatments were control, manure, compost of empty fruit bunch, lateritic soil, pugam (peat fertilizer) type A and type T. The results showed that ameliorants could reduce CO2 emission by approximately 1.7 – 34.4% compare to control except program T. The lowest CO2 emission was produced during 5-7 weeks after the first application of ameliorants. The soil ameliorants should be added every 4 months to control the CO2 emissions from peat soil. Long term observation is needed to more explore the potential of ameliorants to reduce CO2 emission from oil palm plantation in peat soil.

The change in morphological patterns upstream of Ogan River were investigated to analyze land-use and climate change impact on the river meandering. This study aimed to investigate morphological changes of Ogan River in Lengkiti area between 1996 and 2019. Two sets of Landsat areal (1990 and 2016) were used to identify the morphological changes during flood periods. Data analysis used the maximum likelihood approach, t-test and Spearman correlation analysis. The morphometric indicators such as river width (W), meander neck length (L), axis length (A), curvature radius (R), water flow and sinuosity of meander (C) were extracted to identify the morphological pattern of river meandering. Analysis of land-use change used Support Vector Machine (SVM) and kernel function method to interpret the meander parameter change. Ogan River in Lengkiti, such as Batu Kuning and Marga Jaya segments, which have rice field and settlement cover from 1996 to 2019, had been cut off. Cut-off occurred due to landslides that entered river’s body and narrowed riverbed. This fasted river flow even though river discharge was same, caused intensive erosion and sedimentation. The increase in water velocity increased flow power, shortened flow distance and cut-off caused reduced meander’s sinuosity (C).

Climate change poses weather pattern and heat stress on the soil, along with the sea-level rise and groundwater depletion lead to the expansion of soil salinity hazard on arable lands and turn it to saline-prone lands. In Indonesia, soybean profitability and competitiveness over rice and maize are relatively lower leads to the lesser priority in the development. Further, the cultivation area is declined and start utilizing suboptimal lands, including saline-prone lands. Salinity affects soybean productivity; therefore, the use of salinity-tolerant varieties is key to successful soybean cultivation in saline soils. The study was carried out to evaluate the tolerance of soybean varieties under salinity stress. The experiment was conducted at saline field in Lamongan during 2017 dry season. Forty-one soybean varieties were evaluated based on their responses under salinity stress. Research observations included soil electrical conductivity as the salinity measure, plant growth parameters, yield components, and yield. The data were analysed using descriptive statistics and the tolerance to salinity stress was assessed based on Stress Tolerance Index (STI). Evaluated soybean varieties performed various responses to different salinity levels, both in terms of growth and yield parameters. In general, lesser results were observed for most parameters at higher salinity level. Based on the value of STI, 7 varieties were tolerant to salinity but only 2 among them showed yield productivity of >1.5 t ha-1, i.e., Dena 1 and Lokon. Both varieties are very potential to be used as high-yielding parents for salinity tolerant soybean breeding programs.

Plants change their vegetative and reproductive activities as a mechanism to adapt to climate change. This study aimed to document the flushing, flowering and fruiting patterns of 16 Rutaceae species grown at Purwodadi Botanic Garden, East Java. Observations were conducted fortnightly for four years, covering abundances of leaves, flowers and fruits, and used a scoring method from 0–4. The results showed two species with differences in their vegetative activities. Murraya koenigii (L.) Spreng. and Zanthoxylum rethsa DC shed their leaves to a class of 2 (50%). The observed flowering and fruiting patterns included frequency (continual, sub-annual, annual and supra-annual) and class (regular and irregular). The observed species fell into four different frequencies of flowering patterns: annual (nine species), sub-annual (two species), continual (four species) and supra-annual patterns (one species). Most of the observed species performed flowering patterns that differ from their fruiting patterns. Seven species showed same flowering and fruiting patterns, namely Clausena lansium (Lour.) Skeels, Euodia suaveolens var. ridleyi, Glycosmis pentaphylla (Retz.) DC., Luvunga sarmentosa Kurz., Micromelun minutum Wight & Arn., Murraya paniculata (L.) Jack and Triphasia trifolia (Burm.f.) P.Wilson. Some species belonging to regular class performed same flowering time during observation, such as Euodia suaveolens var. ridleyi, Citrus lucida (Scheff.) Mabb., Glycosmis pentaphylla (Retz.) DC, Lunasia amara Blanco, Melicope latifolia (DC.) T.G. Hartley, Murraya paniculata (L.) Jack., Triphasia trifolia (Burm.f.) P.Wilson, and Zanthoxylum rhetsa DC.
