Authors: Shinde Pooja Ramesh , Patel Vipul
Published: September 2022

Bioelectronic medicine is a way of treating in which the electrical communication networks of the body are altered to treat disease. Bioelectric circuitry in every cell creates a resting membrane potential as well as endogenous electric fields that regulate cell function and communication. The theory that cancer is caused by bioelectrical circuitry malfunctions in cells is now widely acknowledged. This opens up the possibility of using bioelectronic medicine to develop new cancer treatments by influencing the disease's bioelectrical properties. To meet societal and technical obstacles, today's individuals aspire to better their quality of life. So, in the midst of all of this, bioelectronic medicine has altered the way we practice medicine and has proven to dramatically enhance healthcare outcomes.  This technique employs a variety of procedures, such as neuromodulation, to treat a specific disease, ailment, or damage. Interfacing electronics with nerves to specifically target the biological processes underlying diseases. In cancer, screening and early detection are crucial for the patient's therapy to be successful and for the patient's survival percentage to grow. For illness diagnosis, therapy, and follow-up, the development of analytical methods for non-invasive detection through the analysis of cancer biomarkers is crucial. Tumor biomarkers are substances or processes that indicate the existence of cancer in the body in clinical situations. These biomarkers can be detected using biosensors, which are popular alternatives to traditional approaches due to their speed, accuracy, and point-of-care applicability. Here we have discussed the consequences of current cancer treatments and bioelectronic medicine a combat for cancer diagnosis and treatment.

Published: September 2022

Aim: This work aimed to develop a sustained released hydrophilic matrix tablet of Aceclofenac for better therapeutic action. 

Background: Conventional dosage form didn't provide the desired level of drug release. Even many-marketed sustained-release tablets didn't always meet the satisfactory level of drug release. It was a challenging job for pharmaceutical scientists to develop a well-sustained release formulation. Keeping this perspective in mind a robust sustained release formulation was designed, developed and optimized with nontoxic, inert viscoelastic, semisynthetic polymers which will be accepted worldwide.

Objective: The objective of this research was to develop an Aceclofenac sustained released matrix tablet, which will deliver the desired level of drug release.

Method: Aceclofenac sustained released tablet was prepared with Methocel                     K-100M Premium (Hydroxypropyl Methylcellulose) and Unigel 270 (Pregelatinized starch). These two excipients were selected as independent formulation variables with three separate levels (high, intermediate and low). Nine batches of hydrophilic matrix tablets of Aceclofenac were prepared according to the 32 Factorial Design with an average weight of 365 mg/tablet. Each prepared batch of tablets was then evaluated for drug content, physical parameters and drug release. Mathematical models were then generated using Analysis of Variance employing Design-Expert Software version 8.0.7.1 for % cumulative release at T1 hr, T4 hr and T7 hr. FTIR spectroscopy was carried out to evaluate drug-excipients interaction after formulation.

Results: Design-Expert Software after analyzing the release data of prepared 9 batches provides an optimized composition of formulation. The optimized batch showed desirable results for cumulative % release (CPR)T1hr, CPR T4hr and CPR T7hr are 35.61, 52.16 and 61.98 respectively. 

Conclusion: Application of statistical experimental design, the physicochemical studies and the in vitro-release study, the mathematically predicted formulation and its manufacturing and validation of aceclofenac sustained-release tablets showed great advancement from the trial-and-error method of development of sustained-release drug delivery systems.

Authors: Ghosh Chandreyi , Saha Moumita , Kulavi Sohini , Chatterjee Sirshendu
Published: September 2022

Background: Coronavirus (SARS-CoV-2), the leading cause of the epidemic in 2019, also known as COVID-19, has raised ongoing global concerns. The most favourable target protein for this flu is 3CLpro (conserved 3-chymotrypsin-like protease), also known as Mpro. Covaxin and Covishield vaccination is going in India. Remdesivir, as well as some antimalarial drugs such as Hydroxychloroquine and Chloroquine, are used for extreme necessity. However, Hydroxychloroquine and Chloroquine and their derivatives are not convenient for those who are suffering from hypertension, diabetes, cardiac arrest, and many more. 

Objective: Here, we choose some bioactive compounds for docking studies with the Mpro of SARS CoV2 and MERS as it is used as the primary target for a comparative study. 

Methods: The docking process was carried out by preparing both 3CLpro proteins, i.e., 2YNA and 6LU7, and then the ligand molecules were downloaded from Pubchem, DrugBank, and Zinc15 databases. Furthermore, SwissAdme and pkCSM software were used for the determination of toxicity and Pharmacokinetic properties (ADMET) properties. Lastly, docking was carried out by the Autodock version 4.2 program, and the docking score was compared to the reference inhibitor Ritonavir. 

Results: Among 17 bioactive compounds used for docking studies, Quercetin, Trans-Resveratol, Kaemferol, and Theaflavin have top, binding affinity for target proteins, i.e., Theaflavin (-14.35 kcal/mol), Quercetin (-11.88kcal/mol), Kaempferol (-9.3 kcal/mol) and Trans-Resveratol (-9.31 kcal/mol) and also obey Lipinski's rule which makes them potential drug candidate against Covid-19 virus. Hence, the application of these plant-based bioactive compounds alone or along with scheduled vaccination may be the best therapeutic approach in the current scenario.

Authors: Sanshi Shridhar , Krishna D., Pramodh , Vatambeti Ramesh
Published: September 2022

The Internet of Things is used in many sectors for different applications in an efficient way. However, sharing huge data to distant destinations is a difficult task such as sending large data from remote area for healthcare application. So that the Delay Tolerant Network is used but, in some cases, the presence of selfish nodes in Delay Tolerant Network may drop all the packets. To overcome this problem the current research affords a novel African Buffalo Delay Tolerant Network with Risk Packet Jump (ABDTN –RPJ) mechanism to improve the communication channel by predicting the selfish and misbehavior node in an earlier stage. Besides, RPJ is introduced to split the huge data to the other neighboring nodes to reduce packet load on the node if the load is greater than the capacity of the node. Finally, the ABDTN –RPJ is implemented and evaluated using the NS2 simulator. The comparison results proved the efficiency of the proposed model by reducing the delay and drop rate.

Authors: Mehringer Martin
Published: September 2022

Die Regelung moderner Gebäudetechnik wird immer anspruchsvoller, Gebäudeautomation passt die Haustechnik optimal an die Bedürfnisse der Nutzer an. Gleichzeitig maximiert sie die Energieeffizienz des Gebäudes. Von Lüftungsgeräten erwarten Facility Manager auf der Basis von Messdaten wie CO2 oder Feuchte einen bedarfsgerechten Betrieb, angepasst an Rahmenbedingungen wie Raum- und Kundenprofile. Dass bei der zunehmenden Komplexität herstellerseits vorinstallierte Regelungstechnik viele Vorteile bietet, zeigt dieser Beitrag. Ein wesentlicher davon ist, dass die Komplexität in den industriellen Prozess vorverlegt und der Ablauf auf der Baustelle professionalisiert wird. Auch die zukünftige ErP-Richtlinie berücksichtigt diese Zusammenhänge.

Theoretical investigations of oxygen vacancy effects in nickel-doped zirconia from ab initio XANES spectroscopy at the oxygen K-edge
Authors: Douma Dick Hartmann , Poaty Lodvert Tchibota , Lamperti Alessio , Kenmoe Stéphane , Raji Abdulrafiu Tunde , Debernardi Alberto , M’Passi-Mabiala Bernard
Published: September 2022

In this study, we present theoretical X-ray absorption near-edge structure (XANES) spectra at the K-edge of oxygen in zirconia containing Ni dopant atoms and O vacancies at varying concentrations. Specifically, our model system consist of a supercell composed of a zirconia (ZrO2) matrix containing two nickel dopants (2Ni), which substitute two Zr atoms at a finite separation. We found the 2Ni atoms to be most stable in a ferromagnetic configuration in the absence of oxygen vacancies. In this system, each Ni atom is surrounded by two shells of O with tetrahedral geometry, in a similar way as in bulk cubic zirconia. The oxygen K-edge XANES spectrum of this configuration shows a pre-edge peak, which is attributable to dipole transitions from O 1s to O 2p states that are hybridized with unoccupied Ni 3d states. The intensity of this pre-edge peak, however, reduces upon the introduction of a single vacancy in the 2Ni-doped zirconia matrix. The corresponding ground state remains ferromagnetic, while one of the nickel atoms adopts a trigonal bipyramidal geometry, and the other one remains in a tetrahedral geometry. Furthermore, the introduction of two vacancies in the 2Ni-doped zirconia results in the two Ni atoms having distorted octahedral and trigonal bipyramidal geometries and being coupled antiferromagnetically in the ground state. Additionally, the oxygen K-edge XANES spectrum shows a further decrease in the intensity of the pre-edge peak, compared to the case of a single vacancy. Thus, the changes in the intensity of the pre-edge peak evidence a major structural change in the local environment around nickel atoms and, by extension, in the zirconia matrix. This change is due to the structural disorder induced by the 2Ni dopants and the O vacancies. Furthermore, the analysis of the XANES signatures shows that the oxidation state of nickel atoms changes with the introduction of oxygen vacancies. Our study therefore shows a possibility to control the oxidation state and magnetic order in a typical diluted magnetic oxide. Such a finding may be crucial for spintronics-related applications.

Authors: Daria Karasalihović Sedlar  , Igor Dekanić  , Lidia Hrnčević
Published: September 2022

The occurrences on the global energy market, increased market instability and the increasingly significant role of geopolitics in energy supply, continually impact the energy supply security which represents the main postulate of the energy politics, as well as a criterion of its successfulness. Assurance of an uninterrupted oil and gas supply is the basic task of each national energy policy. Possibilities and conditions of the supply of primary energy sources, among which oil and natural gas are by far the most important energy sources in relation to their share in energy consumption, and as regards their strategic importance, these represent the basis for assurance of oil and natural gas supply security within the national energy supply. Oil supply security in Croatia is directed towards determining the critical energy supply infrastructure from the viewpoint of energy supply security, towards creating a system for continued oil supply security analysis and monitoring, acting in critical supply situations and towards an elaboration of measures for prevention and amortization in cases of endangerment of energy supply security.

Protection and Reduction of Stateless Persons
Authors:   Center for Public Interest & Human Rights Law Chonnam National University, Choi Kae Young
Published: September 2022

Stateless persons are at high risks of being vulnerable without being recognized for their existence and dignity at the periphery of society. There should be no words that reveal the meaning of nationality better than the expression “the right to have rights.” In this article, the contents of the ‘1954 Convention Relating to the Status of Stateless Persons’ and the ‘1961 Convention on the Reduction of Statelessness’, which are two pillars of the system with which the international society protects stateless persons, were examined and the present situation and future tasks of South Korea in relation to the conventions were reviewed. Although almost 60 years has passed after South Korea joined the Convention Relating to the Status of Stateless Persons, South Korea has not taken any practical action to implement it domestically. A statelessness status recognition procedure to identify stateless persons should be introduced and legislation is necessary to grant the status and rights under the convention to those who applied for statelessness status determination and those who received statelessness status determination. South Korea has not yet joined the Convention on the Reduction of Statelessness, although the number of countries that joined the convention has been increasing globally during the last 10 years. Although it would be most desirable for South Korea to join the Convention on the Reduction of Statelessness and implement it domestically, if it is not possible, at least the legislative improvement to narrow the gap with the convention by revising some provisions of the Nationality Act should be considered as the next best plan.
Climate Change in Korea, the Dutch Urgenda Ruling and its stop-overs and arrival
Authors:   Center for Public Interest & Human Rights Law Chonnam National University, Cornelis Adriaenssens Thomas
Published: September 2022

This research examined how the core of the 2019 Dutch Urgenda ruling (the state is constitutionally obligated to enact concrete and effective measures to prevent climate change, and the court can order its legislation) was borrowed by litigants in the Korean Youth Climate Crisis Constitutional Complaint (2020HonMa89), both directly and indirectly, via a 2020 Irish and 2021 German ruling. To do so, this paper first examined the ECtHR case law that provided the precondition for the Urgenda ruling before examining how the Irish and German judiciary subsequently treated the same issue. It then looked into the Korean constitutional complaint to see what arguments were employed and how foreign case law was used.
As generalizable facts, it concludes that Korean litigants employed foreign case law to 1) stress the incontestability of certain facts (fact-related), 2) as evidence of a global consensus on a legal principle (legal principle-related), 3) to emphasize the effects a ruling could have on Korea’s national judicial prestige (prestige-related), and 4) encourage the judiciary to be more active on the issue (judicial restraint-related).
Egy kamion – 71 halott. Kegyetlen, profitorientált embercsempészek, akik nem válogatnak a módszerekben
Authors: Hertelendi Lajos
Published: September 2022

Aim: I am dealing with the tragedy involving 71 deaths, referred to by the press as the ‚death van’ case. The case received a lot of media coverage, with numerous articles in the Hungarian and foreign press. I present the investigative actions taken by the police, the results of the prosecution and the international cooperation through a thesis prepared by a colleague from the KR NNI (National Investigation Bureau of the Rapid Response and Special Police Service).Methodology: The study is descriptive theoretical research.Findings: The study reveals an interesting criminal case which highlights once again the issue of organised crime, the unscrupulous and inhumane treatment of people smuggling groups, who gain millions in profit, almost waging war on the non-profit police forces serving at the border, with no regard for human dignity and the right to life.Value: The processing of the case may also be of interest to the wider public, but readers, researchers and students can also benefit from it.

We present an entirely new sample of 388 low-mass galaxies (M
⋆ ≤ 1010
M
⊙) that have spectroscopic signatures indicating the presence of massive black holes (BHs) in the form of active galactic nuclei (AGNs) or tidal disruption events. Of these, 70 have stellar masses in the dwarf galaxy regime with 108 ≲ M
⋆/M
⊙ ≲ 109.5. We identify the active galaxies by analyzing optical spectra of a parent sample of ∼23,000 low-mass emission-line galaxies in the Galaxy and Mass Assembly (GAMA) Survey Data Release 4, and employing four different diagnostics based on narrow emission-line ratios and the detection of high-ionization coronal lines. We find that 47 of the 388 low-mass active galaxies exhibit broad Hα in their spectra, corresponding to virial BH masses in the range M
BH ∼ 105.0–7.7
M
⊙ with a median BH mass of 〈M
BH〉 ∼ 106.2
M
⊙. Our sample extends to higher redshifts (z ≤ 0.3; 〈z〉 = 0.13) than previous samples of AGNs in low-mass/dwarf galaxies based on Sloan Digital Sky Survey spectroscopy, which can be attributed to the spectroscopic limit of GAMA being ∼2 mag deeper. Moreover, our multi-diagnostic approach has revealed low-mass active galaxies spanning a wide range of properties, from blue star-forming dwarfs to luminous “miniquasars” powered by low-mass BHs. As such, this work has implications for BH seeding and AGN feedback at low masses.
A Mid-infrared Flare in the Seyfert Galaxy NGC 3786: A Changing-look Event Triggered by an Obscured Tidal Disruption Event?
Authors: Son Suyeon , Kim Minjin , Ho Luis C. , Kim Dohyeong , Kim Taehyun
Published: September 2022

We report an exceptional mid-infrared flare in the Seyfert 1.8 NGC 3786. In the multiepoch data from the Wide-field Infrared Survey Explorer, the nuclear mid-infrared brightness of NGC 3786 appears to vary substantially up to 0.5–0.8 mag around mid-2020. However, there is no evidence of significant variation in the corresponding light curve of the optical band from the Zwicky Transient Facility. This implies that the flare may have been heavily obscured by nuclear dust. Through follow-up spectroscopic observations with Gemini-North after the flare, we find that broad emission lines in Paα and Paβ newly appear, while the broad Hβ emission is marginally detected in the postflare spectrum. In addition, their central wavelengths are systematically redshifted up to 900 km s−1 with respect to the narrow emission lines. This reveals that the flare is associated with the changing-look phenomenon from type 1.8 to type 1. Based on these findings, we argue that the flare is likely to originate from an obscured tidal disruption event, although extreme variation in the accretion rate may not be ruled out completely.
The Impact of Resolution on Double-detonation Models for Type Ia Supernovae

Published: September 2022

Thermonuclear supernovae are the result of the violent unbinding of a white dwarf (WD), but the precise nature of the explosion mechanism(s) is a matter of active debate. To this end, several specific scenarios have been proposed to explain the observable traits of Type Ia supernovae. A promising pathway is the double-detonation scenario, where a WD accretes a shell of helium-rich material from a companion and a detonation in the resulting helium shell is the primary cause of the explosion. Through a set of two-dimensional grid-based simulations of this scenario we clearly distinguish three phases of evolution: external helium-rich detonation, core compressive heating, and a final core carbon burn. Though final disruption of the whole system is achieved at all resolutions, only models with minimum resolutions of 4 km and better exhibit all three phases. Particularly, core compression detonation is only observed for higher resolutions, producing qualitatively different nucleosynthetic outcomes. We identify the effect of finer spatial resolution on the mixing of hot silicon at the interface between the detonating helium layer and the underlying C/O WD as a primary driver of these dynamic differences.
PROBES. I. A Compendium of Deep Rotation Curves and Matched Multiband Photometry
Authors: Stone Connor , Courteau Stéphane , Arora Nikhil , Frosst Matthew , Jarrett Thomas H.
Published: September 2022

We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-type spirals, with matching homogeneous multiband photometry for 1677 of them. PROBES rotation curves originally extracted from Hα long-slit spectra and aperture synthesis H i (21cm) velocity maps typically extend out to a median 2 R
e (or 1 R
23.5,r
). Our uniform photometry takes advantage of GALEX, DESI-LIS, and WISE images and the software AutoProf to yield multiband azimuthally averaged surface brightness profiles that achieve depths greater than 25 mag arcsec−2 (FUV, NUV), 27 mag arcsec−2 (g, r), and 26 mag arcsec−2 (z, W1, and W2). With its library of spatially resolved profiles and an extensive table of structural parameters, the versatile PROBES data set will benefit studies of galaxy structure and formation.
When Specimens Become Environmental Traits: Automating data extraction in aerobiology
Authors: González-Alonso Mónica , Ulayar-Arroyo Jaime , Ariño Arturo H.
Published: September 2022

The identity of a biological specimen can be considered the most basic type of trait: the species (or higher taxon) the specimen belongs to, one of the three most fundamental data elements (along with location and time) that configure the primary biodiversity data record whose quantification may underpin biological monitoring programs. A general image containing specimens (for example, a photo from a surveillance camera), where individual organisms are to be identified, is akin to an image of a single organism where traits are to be recognized: the individual, often distinct organisms in the image, become the traits of the image.

In many cases, automated segmentation and classification/identification and counting of individuals captured within general images containing multiple organisms is most desirable—provided precision and recall exceed a reasonable threshold: that which minimizes the false-positive error rate, as compared to human identification in images. When this occurs, quantitative monitoring data are amenable to good automation, saving much time and human effort.

One particularly well-suited case is that of airborne pollen and spore monitoring, hitherto done manually in most of the world. However, systems are being developed that can recognize atmospheric pollen content from images. Two main approaches are possible: either fully automated systems, or recognition from captured field images. In both cases, some instance of artificial intelligence, most often a convolutional neural network, is tasked with the recognition of pollen and spore types, after proper training, from microscopic images. Several problems exist for the wider adoption of such approaches. Among them, the workflow order of segmentation and identification, the portability of the neural network training for different locations, the differences in performance for distinct particle types, and the generation and archival of images: field images vs. individual (segmented) detected specimens, which call for wholly different approaches to metadata.

In this presentation we review the general outlook of automated airborne pollen and spore monitoring data, and compare performance data in some specific deep learning settings and workflows, based on actual monitoring work, training and tests with real images.
