Published: November 2019

The purpose of this study was to determine the power of enforceability of forestry crime after the decision of the Constitutional Court Number 95/PUU-XII/2014; and the reasons for criminal offenses in the forestry sector so that it fulfills the legality principle after the decision of the Constitutional Court Number 95/PUU-XII/2014. This study used normative juridical research with primary legal materials (laws and decisions of the constitutional court) and secondary legal materials (literature on forestry law and criminal law). Analysis of legal material was carried out using qualitative analysis, describing vague legal norms, then legal interpretation. The results showed that the enforceability of forestry crimes after the decision of the Constitutional Court Number 95 / PUU-XII/2014 was final and binding, with the reason that the criminal cancellation only applies to individuals, did not apply to corporations. The reason for eradicating criminal acts of forestry to fulfill the principle of legality was that the reason for removing crimes in the phrase: “excluded from people who live for generations in the forest” must be interpreted as someone who has for generations taken advantage of regional forests that depend on their livelihoods. For examples clothing, food and shelter from the forest. Whereas “not intended for commercial purposes” was an area forest utilization activity that did not cause forest damage and negative impacts on natural ecosystems.

Authors: Andika A P , Kaikatui R N , Letsoin V
Published: November 2019

The paper proposes the design of a power supply circuit for charging drone batteries using thin-film solar cells. Thin-film solar cells are arranged in parallel to produce a fixed voltage and a large enough current to be able to charge the battery drone. Each output of the solar cell is connected with a step-up device so that the voltage rises to 5 volts. Then all the output from the step-up will be inserted into the power booster supply so that the voltage rises to 28 volts. The unique form of thin-film solar is lightweight and flexible, so the power plant will be placed right above the frame of the drone. The goal is that sunlight can be directly received by the top layer of the solar cell to be converted into voltage. The design of this power supply circuit is expected to be able to increase the length of the drone’s flight in the air.

Hyper-elastic Ricci flow
Authors: Slemrod M.
Published: November 2019

This paper introduces the concept of hyper-elastic Ricci flow. The equation of hyper-elastic Ricci flow amends classical Ricci flow by the addition of the Cauchy stress tensor which itself is derived from the free energy. The main implication of the theory is  a uniformization of material behavior which follows from application of a parabolic minimum principle.
Melancholic Nostalgia, Identity Crisis, and Adaptation in 1950s Hong Kong: Ba Jin’sFamilyon Screen
Authors: Li Yi
Published: November 2019

The communist takeover of mainland China in 1949 created physical, cultural, and political segregation between the mainland and Hong Kong, thus fostering a sense of dislocation and alienation among filmmakers who had migrated to Hong Kong from the mainland. The aim of this study is to explore the symbiosis between nostalgia and adaptation in Hong Kong cinema within the cultural landscape of 1950s Hong Kong, when Cold War politics was operating. With a detailed analysis of the 1953 Hong Kong film adaptation of mainland writer Ba Jin’s novel Family, and a comparative reading with the mainland film version produced in 1956, this study illustrates the cultural and historical significance of nostalgia in the development of Hong Kong cinema. This article further argues that nostalgic sentiment was expressed effectively through adaptations, while simultaneously improving these adaptations artistically and strengthening their political alignment with the mainland.
QMEANDisCo—distance constraints applied on model quality estimation
Authors: Studer Gabriel , Rempfer Christine , Waterhouse Andrew M , Gumienny Rafal , Haas Juergen , Schwede Torsten
Published: November 2019

Motivation

Methods that estimate the quality of a 3D protein structure model in absence of an experimental reference structure are crucial to determine a model’s utility and potential applications. Single model methods assess individual models whereas consensus methods require an ensemble of models as input. In this work, we extend the single model composite score QMEAN that employs statistical potentials of mean force and agreement terms by introducing a consensus-based distance constraint (DisCo) score.

Results

DisCo exploits distance distributions from experimentally determined protein structures that are homologous to the model being assessed. Feed-forward neural networks are trained to adaptively weigh contributions by the multi-template DisCo score and classical single model QMEAN parameters. The result is the composite score QMEANDisCo, which combines the accuracy of consensus methods with the broad applicability of single model approaches. We also demonstrate that, despite being the de-facto standard for structure prediction benchmarking, CASP models are not the ideal data source to train predictive methods for model quality estimation. For performance assessment, QMEANDisCo is continuously benchmarked within the CAMEO project and participated in CASP13. For both, it ranks among the top performers and excels with low response times.

Mountain Plover habitat selection and nest survival in relation to weather variability and spatial attributes of black-tailed prairie dog disturbance
Authors: Duchardt Courtney J , Beck Jeffrey L , Augustine David J
Published: November 2019

Habitat loss and altered disturbance regimes have led to declines in many species of grassland and sagebrush birds, including the imperiled Mountain Plover (Charadrius montanus). In certain parts of their range Mountain Plovers rely almost exclusively on black-tailed prairie dog (Cynomys ludovicianus) colonies as nesting habitat. Previous studies have examined Mountain Plover nest and brood survival on prairie dog colonies, but little is known about how colony size and shape influence these vital rates or patterns of habitat selection. We examined how (1) adult habitat utilization, (2) nest-site selection, and (3) nest success responded to a suite of local- and site-level variables on large prairie dog colony complexes in northeastern Wyoming. Abundance of adult Mountain Plovers was highest on points within older, “medium”-sized (100–500 ha) colonies with high cover of annual forbs and bare ground (5.8 birds km−2), but lower on extremely large (>2,000 ha) colonies (2.1 birds km−2). Nest sites were characterized by high proportions of annual forbs and bare ground and low cactus cover and vegetation height. Nest survival was higher for older nests, and nests with lower cactus cover, and decreased with increasing temperatures. Uncertainty was high for models of daily nest survival, potentially because of 2 competing sources of nest failure: nest depredation and nest abandonment or inviability of eggs. Drivers of these 2 sources of nest failure differed, with inclement weather and higher temperatures associated with nest abandonment or egg inviability. We highlight how prairie dogs alter vegetation structure and bare ground heterogeneously across the landscape, and how this in turn influences bird abundance and nest distribution at different temporal and spatial scales. Furthermore, our work reveals how partitioning the causes of nest failure during nest survival analyses enhances understanding of survival rate covariates.
Predicting the vulnerability of birds to trophic threat posed by phenological mismatch based on nutritional and physiological status of nestlings
Authors: Zhang Shuping , Zhao Lidan , Zhang Xinjie , Liang Wei
Published: November 2019

Lay summaries:

The vulnerability of bird species to trophic threat posed by phenological mismatch should be predicted on the basis of nestling’s nutritional and physiological status rather than only on diet observation. The species is vulnerable to such threat when the alternative food is insufficient to satisfy the nutritional requirement of nestlings.
Evaluating the effect of dorsal muscle biopsies on adult Atlantic salmon growth and marine return rates

Published: November 2019

Increasing conservation and animal-welfare concerns have driven the development of non-lethal sampling of fish populations, with the use of muscle tissue biopsies now being routinely applied as a sampling method in the wild. Crucial to the success of non-lethal sampling, however, is an evaluation of the short- and long-term consequences of the treatment and ultimately the determination of how these may affect organism mortality and other fitness-related traits. The current study evaluated the use of a dorsal muscle biopsies on post-spawned Atlantic salmon emigrating to sea and undertaking a 2-month long-feeding migration before returning to spawn. Using mark-recapture, return rates and growth were compared between fish that were biopsied and externally tagged, and a control group tagged only with external tags. The biopsy treatment showed no lasting effects on fish as estimated from the two key fitness-related parameters. Results, therefore, suggest the technique can be more widely applied to gather information on marine migrating Atlantic salmon and other anadromous fishes that can be intercepted as they descend and ascend rivers during seasonal migrations. Coupled with modern tagging technologies, the use of biopsies may facilitate an improved understanding of movement and its consequences in terms of feeding patterns and growth.

Published: November 2019

The Hippo signaling pathway is a highly conserved pathway controlling organ size, cell proliferation, apoptosis and other biological functions. Recent studies have shown that Hippo signaling pathway also plays important roles in cancer initiation and progression. However, a database offering multi-omics analyses and visualization of Hippo pathway genes in cancer, as well as comprehensive Hippo regulatory relationships is still lacking. To fill this gap, we constructed the Regulation of the Hippo Pathway in Cancer Genome (RHPCG) database. Currently, RHPCG focuses on analyzing the 21 core Hippo-protein-encoding genes in over 10 000 patients across 33 TCGA (The Cancer Genome Atlas) cancer types at the levels of genomic, epigenomic and transcriptomic landscape. Concurrently, RHPCG provides in its motif section 11 regulatory motif types associated with 21 core Hippo pathway genes containing 180 miRNAs, 6182 lncRNAs, 728 circRNAs and 335 protein coding genes. Thus, RHPCG is a powerful tool that could help researchers understand gene alterations and regulatory mechanisms in the Hippo signaling pathway in cancer.

Background and Aims

Epigenetic information delivered by intestinal exosomes can be useful for diagnosing intestinal diseases, such as ulcerative colitis, but the therapeutic effects of intestinal exosomes have not been fully exploited. We herein developed an autologous exosome therapy that could treat intestinal disease without any risk of inducing a systemic immunological reaction.

Methods

Intestinal exosomes were isolated and purified from faeces by our newly developed multi-step sucrose gradient ultracentrifugation method. Lipopolysaccharide [LPS]-activated macrophages were employed to test the in vitro anti-inflammatory ability of intestinal exosomes. To evaluate the in vivo anti-inflammatory activity of our system, we gavaged dextran sulphate sodium [DSS]-induced colitic mice with their own healing phase intestinal exosomes.

Results

Mouse intestinal exosomes are round extracellular vesicles with a hydrodynamic diameter of ~140 [±20] nm and a surface charge of ~-12 [±3] mV. Among the exosomes obtained at four different stages of DSS-induced ulcerative colitis [1, before treatment; 2, DSS-treated; 3, healing phase; and 4, back to normal], the healing phase exosomes showed the best in vitro anti-inflammatory effects and promotion of wound healing. Moreover, oral co-administration of autologous healing phase exosomes with DSS was found to significantly reduce the risk of a second round of DSS-induced ulcerative colitis in mice.

Conclusions

Intestinal exosomes obtained during the healing phase that follows induced intestinal inflammation could strongly promote wound healing in the host. Oral administration of autologous exosomes from the healing phase could be a safe and effective approach for treating the ulcerative colitis of a given patient in the context of personalised medicine.
