Abstract

Policymakers need to drive the rapid expansion of renewable energy technologies, and additionally channel the limited national potential of biomass into areas where it can provide the greatest benefit to the energy system. But do current policy instruments promote the use of biomass in these areas? In this study, shortterm energy scenarios are generated using the BenOpt model while considering both current and alternative policy instruments. The results are compared with long-term, cost-optimal energy scenarios in regard to the use of biomass. The analysis reveals that e.g. the GHG-quota instrument does not promote the use of biofuels in the hard-to-electrify areas of the transport sector, where they should be cost-optimally allocated according to long-term energy scenarios. This might lead to counterproductive developments in the passenger road sector, but at the same time helps to ramp up biofuel capacities required in shipping and aviation in the long term. In contrast, alternative policy scenarios show that the sole instrument of a high CO2-price is more conducive to direct electrification and at the same time displaces more fossil fuels until 2030 than the GHG-quota alone. This instrument also promotes the optimal use of biogas plants in the power sector according to long-term cost-optimal developments. However, a high CO2- price alone is not sufficient in the heat sector, w here additional instruments are required to scale up renewable technologies and use biomass efficiently instead ofsimply covering the base load demand.
Domain Independent Heuristics for Online Stochastic Contingent Planning
Authors: Blumenthal Oded , Shani Guy 
Published: October 2023

Abstract
Partially observable Markov decision processes (POMDP) are a useful model for decision-making under partial observability and stochastic actions. Partially Observable Monte-Carlo Planning is an online algorithm for deciding on the next action to perform, using a Monte-Carlo tree search approach, based on the UCT (UCB applied to trees) algorithm for fully observable Markov-decision processes. POMCP develops an action-observation tree, and at the leaves, uses a rollout policy to provide a value estimate for the leaf. As such, POMCP is highly dependent on the rollout policy to compute good estimates, and hence identify good actions. Thus, many practitioners who use POMCP are required to create strong, domain-specific heuristics. In this paper, we model POMDPs as stochastic contingent planning problems. This allows us to leverage domain-independent heuristics that were developed in the planning community. We suggest two heuristics, the first is based on the well-known hadd heuristic from classical planning, and the second is computed in belief space, taking the value of information into account.
Total collision in a four-body problem with Jacobi potential
Authors: Bakker Lennard , Santoprete Manuele , Stoica Cristina 
Published: October 2023

Abstract
We study the dynamics of a spatial four-body problem where the bodies maintain a rhombus-shape configuration at all times: two of the bodies of equal mass move in the horizontal plane symmetrically with respect to the origin while another pair of bodies of equal mass move symmetrically opposed along the vertical axis. The bodies interact via the Jacobi potential, an attractive binary potential of the form $-1/x^2$, where $x$ is the distance between the particles.
We use appropriate transformations to blow up total collision into a manifold pasted onto the phase space for all levels of energy. We find that the topology of the total collision manifold changes as the angular momentum varies, and also that the dynamics on the collision manifold changes as a function of angular momentum and the mass ratio.
We also give a qualitative description of the global flow of the problem for negative energy. This description utilizes knowledge concerning the flow on and near the collision manifold, the presence of an additional integral of motion, and takes advantage of the time-reversing symmetry inherent in the system of equations.

Published: October 2023

Abstract:
The existence of the blood-brain barrier (BBB), a densely woven network of blood
vessels and endothelial cells designed to prevent the infiltration of foreign substances into the
brain, the methods employed in developing treatments for neurodegenerative disorders (NDs)
such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Multiple sclerosis, Amyotrophic lateral sclerosis, and others, pose significant challenges and complexities. These illnesses
have had a terrible impact on the human population's health. Because early detection of these
problems is poor and no good therapy has been established, they have emerged as the biggest lifethreatening healthcare burden worldwide compared to other significant illnesses. Traditional drug
delivery techniques do not offer efficient treatment for NDs due to constraints in the BBB design,
efflux pumps, and metabolic enzyme expression. Nanotechnology has the potential to significantly enhance ND therapy by utilizing systems that have been bioengineered to engage with living
organisms at the cellular range. Compared to traditional techniques, nanotechnological technologies have several potential ways for crossing the BBB and increasing therapeutic efficacy in the
brain. The introduction and growth of nanotechnology indicate promising potential for overcoming this issue. Engineered nanoparticles coupled with therapeutic moieties and imaging agents
with dimensions ranging from 1-100 nm can improve effectiveness, cellular uptake, selective
transport, and drug delivery to the brain due to their changed physicochemical properties. Conjugates of nanoparticles and medicinal plants, or their constituents known as nano phytomedicine,
have recently gained importance in developing cutting-edge neuro-therapeutics due to their abundant natural supply, promising targeted delivery to the brain, and lower potential for adverse effects. This study summarizes the common NDs, their prevalence and pathogenesis, and potential
herbal nanoformulation for treating NDs.
Common Causes of False Positive and False Negative Results in Amphetamine
Screening Tests
Authors: Stoeva Stanila 
Published: October 2023

Abstract:
The need for toxicological screening of amphetamine users is growing in parallel with its
increasing abuse. At the same time, it turns out that these substances most often give false results in
rapid drug immunoassay. Therefore, the aim of the present work was to investigate the sources of
false positive or false negative results. For this purpose, an analysis of the literature sources in the
databases of Google Scholar, PubMed, and Science Direct, was made. The results showed that a
number of prescription or OTC medications can cause false positive results due to cross-reactivity
(ephedrine, pseudoephedrine, labetalol, metoprolol, some antidepressants, metformin, ranitidine,
ofloxacin, selegiline, etc.). In this regard, alternative medications for patients who often have to undergo
such screening have been proposed. Some possibilities of unintentionally or intentionally inducing
false negative results have also been highlighted. Popular approaches to fooling the screening
test are diluting the urine, adding adulterants (marketed products or homemade chemicals), and
providing foreign or synthetic urine. Summarizing the possible sources of errors in drug screening is
expected to objectify the interpretation of the obtained results.

Aim. To determine the general patterns and distinctive features of the formation of the HIV epidemic in chronology in various administrative territories of the Vologda Region.Materials and methods. The data of the epidemiological survey maps of HIV infection foci, reports «Causes of mortality of HIV-infected», statistical observations were analyzed: form No. 61 «Information on the contingent of HIV-infected patients», form No. 4 of the Federal State Statistical Observation, forms of the Vologda Regional Center for the Prevention and Control of AIDS and Infectious Diseases, materials of the North-Western District Center for the Prevention and Control of AIDS. Dynamic monitoring of the HIV epidemic in the Vologda Region (since 1995) and evaluation of the effectiveness of the national project to combat HIV infections were carried out.Results and discussion. On the territory of the Vologda Region, the trend of stability of the indicator of HIV infection remains. The prevalence of the population is increasing, accompanied by the identification of patients at late stages with the manifestation of secondary diseases. In the region, the HIV epidemic corresponds to the main trends of the epidemic process in the North-Western Federal District (NWFD) with some differences. The dominant transmission routes are parenteral (39.9% in 2021) and heterosexual. Over the past 5 years, there has been an upward trend in homosexual transmission of infection among men who have sex with a men (MSM), the share of which increased in 2021 by 2 times compared to 2017 and amounted to 3.1%. The detection rate in 2021, calculated for 100 thousand surveyed, in the Vologda Region was 111.3 (in the NWFD — 160.1). The highest detection rate of HIV infection was observed among MSM — 14.3% (in the NWFD — 4.1%), among injecting drug users (IDUs) — 1.0% (in the NWFD — 1.1%), among persons in prison — 1.8% (in the NWFD — 1.8%). One of the main causes of death in HIV-infected patients is the late detection of the disease and the initiation of antiretroviral therapy (ART). During the entire period of observation, the epidemic was most intense in Cherepovets and Vologda, since 2000 there has been a gradual spread of infection with involvement in the process in rural areas.Conclusion. The results obtained demonstrate the importance of implementing different models of the main stages of diagnosis, prevention and treatment of people in urban and rural areas, which is included in the developing concept of personalized HIV medicine. It is necessary to carry out additional measures for the active identification and registration of dispensary patients, the formation of adherence to dispensary monitoring and therapy, the timely appointment of ART, the introduction of new approaches to providing medical care to HIV-infected patients in the districts of the region.

Published: October 2023

The objective was to evaluate the renal vascular resistive index as a predictor of acute kidney injury in children of the first year of life in congenital heart surgery with cardiopulmonary bypass. Materials and methods. A single-center retrospective study included 150 patients with congenital heart disease (CHD), whose renal vascular resistive index (RVRI) was assessed at the stages of surgical interventions (before surgery, 6 hours after the end of cardiopulmonary bypass (CPB) and the 1st day after surgery). Acute kidney injury (AKI) was diagnosed according to the KDIGO criteria. To achieve comparability of the obtained groups, pseudo-randomization was performed. After compensating for the uneven distribution of cofounders, groups of patients comparable in number were obtained (n= 52 in both groups). Results. The renal vascular resistive index at the stages of surgical intervention did not differ among patients with and without acute kidney injury. The baseline of creatinine was higher in the group without AKI, however, starting from the 1st postoperative day, it prevailed in the group with AKI. The chances of developing AKI in male patients were 74% lower. Conclusion. The absence of a predictive ability of the renal vascular resistive index in acute kidney injury in children aged 1 month to 1 year with congenital heart disease operated with cardiopulmonary bypass was demonstrated.

The objective was to compare the optic nerve sheath diameter measured by CT (ODSN-CT) with the level of compression of the mesencephalic cisterns and the midline shift in the diagnosis and prediction of intracranial hypertension (ICH) during the first 3 days after brain injury. Materials and methods. We examined 90 patients with TBI, the average age was 34.2 ± 13 years, GCS < 9. All patients had invasive ICP monitoring. At the time of implantation of the ICP sensor, intracranial hypertension (ICH) was in 11 (12%) patients; later, during the first 3 days, the development of ICH was in 58 (64%) patients. All patients underwent computed tomography of the head at the time of hospitalization: mesencephalic cisternae was compressed in 57 (63%) and midline shift was observed in 34 (38%) patients, mean value of ONSD-CT was 7.26 ± 0.9 mm, maximum value of ONSD-CT was 7.34 ± 0.9. We used correlation analysis, logistic regression and ROC-analysis.Results. The level of mesencephalic cisternae compression, mean and maximum value of ONSD-CT correlated with the ICP value measured at the time of ICP sensor implantation and during the first 72 hours after brain injury (p < 0.05). Midline shift did not correlate with ICP value measured at the time of sensor implantation and during the first 72 hours after brain injury (p > 0.05). In the diagnosis of ICP > 20 mm Hg at the time of implantation of the sensor – the average ONSD-CT, AUC 0.902 ± 0.046 (0.812; 0.991), cut-off 7.8 mm with sensitivity and specificity of 82 and 80%, respectively. When predicting ICP > 20 mm Hg in the first 72 hours - the maximum ONSD-CT, AUC 0.815 ± 0.047 (0.724; 0.907), cut-off 7.1 mm with sensitivity and specificity of 85 and 66%, respectively.Conclusions. The ONSD-CT parameter is an independent diagnostic and prognostic criterion of ICH in the first 3 days in patients with severe TBI. The mean ONSD-CT can be used to diagnose ICH along with such signs of ICP as level of mesencephalic cisterna compression and midline shift and to make a decision on invasive ICP monitoring. The maximum value of ONSD-CT can be used to assess the probability of ICH in the first three days after TBI
