Why do valence asymmetries emerge in value learning? A reinforcement learning account
Authors: Hao Chenxu , Cabrera-Haro Lilian E. , Lin Ziyong , Reuter-Lorenz Patricia A. , Lewis Richard L.
Published: December 2022

The Value Learning Task (VLT; e.g., Raymond & O’Brien, 2009) is widely used to investigate how acquired value impacts how we perceive and process stimuli. The task consists of a series of trials in which participants attempt to maximize accumulated winnings as they make choices from a pair of presented images associated with probabilistic win, loss, or no-change outcomes. The probabilities and outcomes are initially unknown to the participant and thus the task involves decision making and learning under uncertainty. Despite the symmetric outcome structure for win and loss pairs, people learn win associations better than loss associations (Lin, Cabrera-Haro, & Reuter-Lorenz, 2020). This learning asymmetry could lead to differences when the stimuli are probed in subsequent tasks, compromising inferences about how acquired value affects downstream processing. We investigate the nature of the asymmetry using a standard error-driven reinforcement learning model with a softmax choice rule. Despite having no special role for valence, the model yields the learning asymmetry observed in human behavior, whether the model parameters are set to maximize empirical fit, or task payoff. The asymmetry arises from an interaction between a neutral initial value estimate and a choice policy that exploits while exploring, leading to more poorly discriminated value estimates for loss stimuli. We also show how differences in estimated individual learning rates help to explain individual differences in the observed win-loss asymmetries, and how the final value estimates produced by the model provide a simple account of a post-learning explicit value categorization task.

The coefficients of the second order nonlinear optical dij tensor were calculated by the method developed on the basis of the dielectrics theory of Phillipson and Van Wetchen and the Levin charge coupling model for lithium niobate crystals doped with zinc (3.43–5.84 mol %). In LiNbO3 : Zn crystals, the concentration dependences of the nonlinear optical coefficients showed several regions with maxima and minima; the most noticeable changes in the nonlinear optical coefficients were observed at threshold concentrations of zinc oxide in the melt. Doping with zinc increases the conversion efficiency of the second harmonic radiation, such the crystals are more promising for use in nonlinear optics than a nominally pure lithium niobate crystal.

On the concept of war in Plato's dialogue "Alcibiades I"
Authors: Neretina Svetlana
Published: December 2022

Plato's dialogue "Alcibiades I" introduces the very essence of philosophical business — knowledge, as far as it is accessible to man. The dialogue conducted by the wise Socrates and the young vain Alcibiades, who, wanting to play the first role in politics, decided to "fill the whole, one might say, humanity with his name and power," i. e. to unleash a war. Socrates, crushed by such a desire, prompted Alcibiades to consider what are called the "last questions": war and peace. Unfolding the argument, he discusses the concepts of justice/injustice, right/lawlessness, good/evil, which turn out to be ambiguous, as well as the idea of freedom: on the one hand (Socrates) it is understood as a characteristic of virtue, and on the other (Alcibiades) — self-will and voluntarism. The need for Alcibiades to remain "himself" presupposed the tyrannically accessible possibility of war, which was a way of exercising his "freedom". The war turned out to be a perversion of the world, an "adventure of the spirit" and "the greatest grief" that people bring released forces that the world does not know how to use
Is Tour Guiding Possible in Metaverse?
Authors: ŞENGEL Ümit , ÖZESKİCİ İmran
Published: December 2022

Researchers are wondering to what extent it is possible for professions to take place in the coming years in the Metaverse world, which has attracted more attention over time. In this context, it is aimed to discuss whether it is possible to practice the profession of tour guiding in Metaverse. The study is based on a conceptual research. Since the Metaverse is not a well-known and easy-to-understand concept, compilation studies that constitute conceptual and semantic integrity are needed before empirical studies on the subject. With the updating of the possibilities offered by the virtual universe over time, it is thought that tour guiding in the Metaverse, which seems impossible at the moment, may be possible in the future. Technological developments and forecasts for the future show this. Technology is one of the indispensable elements of human life. The basis of all kinds of materials used today is based on advanced technology. While developing technology paves the way for the formation of a new order in human life, it also provides a source for the emergence of different concepts within this order. One of these concepts is Metaverse. Metaverse, which is the basis of the intertwining of reality and virtual environment, constitutes the main subject of the research. The study is suitable for the "what awaits us in the future?" view on people due to the uncertainty of the Metaverse world, which is a result of the ever-developing advanced technology.

The use of the indicator of membrane-bound calcium content (fluorescence intensity of the complex calcium + chlortetracycline + membrane) as a biomarker of the functional state (growing or fully grown oocytes) of donor oocytes in the technology of extracorporeal maturation of female gametes Sus scrofa domesticus is substantiated. The addition of highly dispersed silica nanoparticles with granulosa cells to culture media at in vitro maturation promotes the mobilization of calcium ions from intracellular stores of oocytes that have not finished the growth phase in vivo.

Authors: ELLERGEZEN Pınar , ALP Alev , ÇAVUN Sinan
Published: December 2022

Aim: The major target of this research is to examine whether there is any connection between the levels of vitamin D and anti-inflammatory mediators in patients with fibromyalgia syndrome (FMS). Materials and Methods: The study contains 30 FMS diagnosed and 25 healthy female individuals and the determination of FMS was made according to the standards of 2010 American College of Rheumatology (ACR). Vitamin D, vitamin D receptor (VDR), vitamin D binding protein (VDBP) levels, and anti-inflammatory cytokine (IL-4, IL-10, TGF-β) levels in the serum of patients with FMS and healthy individuals were measured using enzyme-linked immunosorbent assay (ELISA).Results: The concentrations of vitamin D, VDR, and VDBP were determined to be higher in healthy controls than in patients with FMS (p<0.001). Correlating with this, IL-4, IL-10, and TGF-β levels were measured remarkably higher in the healthy group than in the FMS patients (p<0.001). Conclusion: Low vitamin D levels may cause a decrease in anti-inflammatory cytokine levels and their immunosuppressive effect in FMS.

Authors: ALP Mahmut
Published: December 2022

Bu çalışmada kol ve bacak hacminin 10-12 yaş yüzücülerde sprint yüzme performansları ile ilişkisinin incelenmesi amaçlanmıştır. Çalışmaya lisanslı olarak yüzme sporu yapan 10 kız ve 10 erkek toplam 20 yüzücü “Veli Bilgilendirme/İzin Formu” doldurtularak katıldı. Yüzücülere kol hacmi, bacak hacmi ve tüm stillerde 50 m yüzme performans ölçümleri uygulandı. Veriler istatistik paket programında tanımlayıcı istatistik ve normal dağılım göstermedikleri için non-parametrik korelasyon analizi ile incelendi. Yüzücülerin toplam kol hacmi ve yüzme performansları arasındaki ilişki incelendiğinde kelebek stilinde ilişki anlamsızken; diğer stillerde pozitif yönde anlamlı ilişki tespit edildi. Toplam bacak hacmi değerleri ve yüzme performansları arasındaki ilişki de ise tüm stillerde pozitif yönde anlamlı ilişkiye rastlandı. Sonuç olarak, sprint yüzme karakteristiğinde anaerobik enerji sisteminin baskınlığı ve paralel olarak ilgili enerji sistemine kas hacmi ve kütlesinin doğru orantılı olduğunu söyleyebiliriz. Ek olarak, küçük yaş dahi olsa kuvveti geliştirmeye yönelik yapılan kara ve su antrenmanlarının kas kütlesinde hipertrofi, kasın enerji mekanizmasında ise anaerobik katkıları olduğunu düşünmekteyiz. Yüzme branşında fiziksel ve fizyolojik tepkilerin durumu etkileyen önemli faktörler göz önüne alındığında, performans takibi açısından çalışmamız sonuçlarının yüzme antrenörlerine ve yüzücülere referans değer katacağını düşünüyoruz.

On the Presence of Metallofullerenes in Fullerene-rich Circumstellar Envelopes

Published: December 2022

The presence of neutral C60 fullerenes in circumstellar environments has been firmly established by astronomical observations as well as laboratory experiments and quantum-chemistry calculations. However, the large variations observed in the C60 17.4 μm/18.9 μm band ratios indicate that either additional emitters should contribute to the astronomical infrared (IR) spectra or unknown physical processes exist besides thermal and UV excitation. Fullerene-based molecules such as metallofullerenes and fullerene-adducts are natural candidate species as potential additional emitters, but no specific specie has been identified to date. Here we report a model based on quantum-chemistry calculations and IR spectra simulation of neutral and charged endo(exo)hedral metallofullerenes, showing that they have a significant contribution to the four strongest IR bands commonly attributed to neutral C60. These simulations may explain the large range of 17.4 μm/18.9 μm band ratios observed in very different fullerene-rich circumstellar environments like those around planetary nebulae and chemically peculiar R Coronae Borealis stars. Our proposed model also reveals that the 17.4 μm/18.9 μm band ratio in the metallofullerenes simulated IR spectra mainly depends on the metal abundances, ionization level, and endo/exoconcentration in the circumstellar envelopes. We conclude that metallofullerenes are potential emitters contributing to the observed IR spectra in fullerene-rich circumstellar envelopes. Our simulated IR spectra indicate also that the James Webb Space Telescope has the potential to confirm or refute the presence of metallofullerenes (or even other fullerene-based species) in circumstellar environments.
Measuring the Dust Masses of Protoplanetary Disks in Lupus with ALMA: Evidence That Disks Can Be Optically Thick at 3 mm

Published: December 2022

Accurate disk mass measurements are necessary to constrain disk evolution and the timescale of planet formation, but such measurements are difficult to make and are very dependent on assumptions. Here, we look at the assumption that the disk is optically thin at radio wavelengths and the effect of this assumption on measurements of disk dust mass. We model the optical to radio spectral energy distributions of 41 protoplanetary disks located in the young (∼1–3 Myr old) Lupus star-forming region, including 0.89 1.33 and 3 mm flux densities when available. We measure disk dust masses that are ∼1.5–6 times higher than when using the commonly adopted disk dust mass equation under the assumption of optically thin emission in the (sub)millimeter range. The cause of this discrepancy is that most disks are optically thick at millimeter wavelengths, even up to 3 mm, demonstrating that observations at longer wavelengths are needed to trace the fully optically thin emission of disks.
Is There a Dynamic Difference between Stealthy and Standard Coronal Mass Ejections?

Published: December 2022

Stealthy coronal mass ejections (CMEs), lacking low coronal signatures, may result in significant geomagnetic storms. However, the mechanism of stealthy CMEs is still highly debated. In this work, we investigate whether there are differences between stealthy and standard CMEs in terms of their dynamic behaviors. Seven stealthy and eight standard CMEs with low speeds are selected. We calculate two-dimensional speed distributions of CMEs based on the cross-correlation method, rather than the unidimensional speed, and further obtain more accurate distributions and evolution of CME mechanical energies. Then we derive the CME driving powers and correlate them with CME parameters (total mass, average speed, and acceleration) for standard and stealthy CMEs. Besides, we study the forces that drive CMEs, namely, the Lorentz force, gravitational force, and drag force due to the ambient solar wind near the Sun. The results reveal that both standard and stealthy CMEs are propelled by the combined action of those forces in the inner corona. The drag force and gravitational force are comparable with the Lorentz force. However, the impact of the drag and Lorentz forces on the global evolution of stealthy CMEs is significantly weaker than that on standard CMEs.

On 2022 July 13, NASA released to the whole world the data obtained by the James Webb Space Telescope (JWST) Early Release Observations (ERO). These are the first set of science-grade data from this long-awaited facility, marking the beginning of a new era in astronomy. In the study of the early universe, JWST will allow us to push far beyond z ≈ 11, the redshift boundary previously imposed by the 1.7 μm red cutoff of the Hubble Space Telescope (HST). In contrast, JWST’s NIRCam reaches ∼5 μm. Among the JWST ERO targets there is a nearby galaxy cluster SMACS 0723-73, which is a massive cluster and has been long recognized as a potential “cosmic telescope” in amplifying background galaxies. The ERO six-band NIRCam observations on this target have covered an additional flanking field not boosted by gravitational lensing, which also sees far beyond HST. Here we report the result from our search of candidate objects at z > 11 using these ERO data. In total, there are 87 such objects identified by using the standard “dropout” technique. These objects are all detected in multiple bands and therefore cannot be spurious. For most of them, their multiband colors are inconsistent with known types of contaminants. If the detected dropout signature is interpreted as the expected Lyman break, it implies that these objects are at z ≈ 11–20. The large number of such candidate objects at such high redshifts is not expected from the previously favored predictions and demands further investigations. JWST spectroscopy on such objects will be critical.

Terrestrial exoplanets such as TRAPPIST-1e will be observed in a new capacity with the JWST/Near Infrared Spectrograph (NIRSpec), which is expected to be able to detect CO2, CH4, and O2 signals, if present, with multiple coadded transit observations. The CO2-CH4 pair in particular is theorized to be a potential biosignature when inferred to be in chemical disequilibrium. Here, we simulate TRAPPIST-1e’s atmosphere using the ExoCAM general circulation model, assuming an optimistic haze-free, tidally locked planet with an aquaplanet surface, with varying atmospheric compositions from 10−4 bar to 1 bar of partial CO2 pressure with 1 bar of background N2. We investigate cases both with and without a modern Earth-like CH4 mixing ratio to examine the effect of CO2 and CH4 on the transmission spectrum and climate state of the planet. We demonstrate that in the optimistic haze-free cloudy case, H2O, CO2, and CH4 could all be detectable in less than 50 transits within an atmosphere of 1 bar N2 and 10 mbar CO2 during JWST’s lifespan with NIRSpec as long as the noise floor is ≲10 ppm. We find that in these optimistic cases, JWST may be able to detect potential biosignature pairs such as CO2-CH4 in TRAPPIST-1e’s atmosphere across a variety of atmospheric CO2 content, and that temporal climate variability does not significantly affect spectral feature variability for NIRSpec PRISM.

Секундарниот Сјегренов синдром (сСС) претставува заболување на сврзното ткиво кое се карактеризира главно со појава на ксерофталмија и ксеростомија, во склоп на други автоимуни заболувања. Преваленцијата на сСС кај пациенти со ревматоиден артритис (РА) е различна во различни држави, но се претпоставува дека изнесува околу 10% од сите пациенти со РА, при што околу 20% од овие имаат супклинички манифестации. Ова претставува голема суппопулација на пациенти со РА, при што клиничките импликации на коегзистирањето на двете болести сèуште се недоволно испитани. Цели: Да се анализираат ефектите на појавата на сСС врз болеста, односно поврзаноста на овој синдром со активноста и еволутивноста на болеста, присуството на серолошки и имунолошки маркери, времетраењето на болеста и квалитетот на животот кај пациенти со РА. Материјал и методи: Беа испитани 42 пациенти на возраст од 18 до 70 години, дијагностицирани според критериумите на EULAR (2010).  Дваесет пациенти беа со РА и сСС и 22 пациенти со РА без придружен сСС. Групите беа со слични карактеристики во однос на пол, возраст и времетраење на болеста. Беа анализирани:  појавата на сСС и нејзината зависност од возраста и полот на пациентите, демографските податоци, траењето на болеста, присуството на вонзглобни манифестации, а беа направени и серолошки тестови (позитивниот RF, anti-CCP). Активноста на болеста беше анализирана преку индексот на активност на болест - DAS28 (Disease Activity Score 28), а квалитетот на живот на пациентите преку HAQ-DI (Health Assessment Questionnaire – Disability Index). Беше анализиран бројот на болни и отечени зглобови, VAS (визуелна аналогна скала на болка), седиментација на еритроцити (ESR), CRP, а беа направени и имунолошки тестови (SSA, SSB, antidsDNA, ANA, antiU1snRNP) и по потреба други имунолошки и серолошки тестови). Резултати: Кај испитаните пациенти немаше статистички сигнификантна разлика во ESR, CRP, DAS28, HAQ-DI, серопозитивност кон RF или anti-CCP, како и присуството на antidsDNA, ANA или antiU1snRNP, како и траење на болеста. Пациентите во РА групата беа во поголем број, со повеќе отечени зглобови и повисока VAS. Постоеше статистички сигнификантна разлика во позитивноста на SSA и SSB антителата во двете групи. Немаше разлика во лекувањето на пациентите во двете групи. Заклучок: Не постои статистички сигнификантна разлика во нивото на активност на болеста и квалитетот на живот на пациентите со РА во споредба со оние со сСС.

The first human cases of coronavirus disease (COVID-19), a disease caused by the new coronavirus, was reported on December 31, 2019 in China for the first time. Тhe virus was named temporarily as 2019 new coronavirus (2019 novel coronavirus-2019 -nCoV), or  finally as SARS-CoV-2. The aim of this paper is to give an overview of the laboratory detection of SARS-CoV-2 virus with reverse transcriptase - polymerase chain reaction (RT-PCR) in real time, as well as detection of viral mutations in the Laboratory for virology at the Institute of Public Health. The samples used in the study were taken from all geographical regions in North Macedonia, including the 10 regional Centers for Public Health throughout the country, from hospital patients, from COVID19 hospitals across the country and from the COVID19 checkpoint at the Institute of Public Health. All samples were tested using RT-PCR in real time. Additional assays were applied for identification of the circulating variants. The continuous surveillance of the variants of concern (VOC), as well as the newly emerged variants can allow the public health officials to modify their approach to disease control and management and intervene more effectively as well as in a timely manner in order to prevent major morbidity and mortality from COVID-19.

Hepatitis B is the world’s most common blood‑borne viral infection, accounting for 2 billion infections, 350 million carriers, and 6 lakh deaths annually. Aim of the paper is to determine the level of knowledge among healthy population in North Macedonia regarding Hepatitis B virus infection. Material and methods: A community‑based cross‑sectional study was undertaken. Questionnaire was administered to 600 healthy individuals, who heard about hepatitis B. Data handled and analyzed by using statistical package SPSS. Results: The profile of those who give the correct answer regarding the cause of hepatitis B that it is a virus are women (65.3%), aged 40 to 49 (42.8%), by nationality are Macedonian, have higher education (52.8%), 92.8% live in urban areas, 74.3% are married, employed (79.2%) and have a moderate monthly income (68.9). About one‑third of the sample said that loss of appetite, diarrhea, nausea/vomiting also associated with hepatitis B. There is a significant difference in knowledge related to early (prodromal) (symptoms such as cold and flu - fever, runny nose, cough) symptoms of hepatitis infection. Only 17.7% give the correct answer that they register, and 81.7% do not. Jaundice is one of the common symptoms of hepatitis, 32.2% give the correct answer, and 25.8% of the symptoms that are present and common are nausea, vomiting and loss of appetite. Conclusions: Important knowledge deficits about the routes of hepatitis B transmission/prevention were identified. Continued efforts should be made to develop and implement hepatitis B educational campaigns/health promotion for these communities.

So far, the literature data have presented a combination of several autoimmune triggered disease in patients, but the research is scarce and very limited. In this context we present a rare case of autoimmune thyroiditis with a concomitant autoimmune hepatitis. Hashimoto thyroiditis is an autoimmune disorder in which immune cells lead to impairment, destruction of the thyroid hormone producing cells and tissue fibrosis with consecutive primary hypothyroidism. Autoimmune hepatitis is a chronic liver disease with unknown etiology, which is assumed to be T cell mediated condition where immune cells produce autoantibodies responsible for inflammation, destruction and fibrosis of the hepatic parenchyma. In this case report, we discuss the possible correlation in the spectrum of autoimmune diseases concerning Hashimoto thyroiditis and autoimmune hepatitis.

Congestive heart failure is a growing global health problem. Left ventricular assist device (LVAD) is a method used to extend the life of patients with congestive heart failure as a definitive treatment or to “bypass” the period until heart transplantation. Ventricular arrhythmias in patients with LVAD are not uncommon. The aim of this paper is to present the case of a patient with an already implanted LVAD and the need for appropriate interdisciplinary medical treatment. Case report: We present the case of a 54-year old patient, A. D., with implanted LVAD - HeartMate 3 due to severe congestive heart failure. The patient was admitted with jaundice at the PHIU Clinic for Gastroenterohepatology with performed endoscopic retrograde cholangiopancreatography (ERCP)) procedure and a stent was placed in the choledochus duct. Immeasurable blood pressure and pulse were recorded in this patient. The ECG was approaching VF (ventricular fibrillation) and it was all asymptomatic by the patient.  LVAD mechanical pump leads to continuous blood flow, which means that patients with LVAD not infrequently have no pulse or measurable blood pressure. Also, in patients with LVAD, ECG pulses are with electrical disturbances. VF and ventricular tachycardia (VT) are ventricular arrhythmias that are often seen on ECG in patients with implanted LVAD. Usually these arrhythmias occur with unknown duration and terminate spontaneously. Conclusion: Patients with LVAD are prone to cardiac arrhythmias. The continuous development of medical devices leads to a continuous educational and clinical approach to patients.

It has a characteristic fundoscopic appearance consisting of a large funnel-shaped cavity on the optical disc. We register an unusual congenital anomaly of the optic disc in a three-year-old female child.
Some international experiences from screening for colorectal cancer
Authors: Sazdovska Sanja
Published: December 2022

Colorectal cancer (CRC) is an important public health problem, especially in Europe. Every year approximately 435,000 new cases are being diagnosed with colorectal cancer. Half of these people die, which makes this type of cancer a second-rated mortality cause in Europe. The main aim of this paper was to make a literature search related to colorectal cancer with a focus on the developed Western European countries and countries close to the Republic of North Macedonia.
This paper also intended to provide a picture of the early screening for colorectal cancer as the most efficient method for prevention and early detection of colorectal cancer and its application in some developed countries. For achieving the objectives set out in this paper, a survey of the available literature (both electronic and print) as well as of the grey literature was made. A systematic search of the following databases was made: PubMed, European Commission, and Google Scholar. The inclusion criteria were studies conducted between 2008 and 2020, with an emphasis on the newest studies and those published in the neighboring countries. According to the WHO recommendations and practices in modern countries, colorectal cancer should be identified as a serious public health problem. This includes unclear cause of its occurrence, as well as all possible risk factors which make it almost possible to implement an adequate prevention program.
The most acceptable sensitive test for implementation of the screening program for colorectal cancer is the utilization of the FOB test. It is of great importance to follow-up patients with a positive FOB test as well as to offer easy access to health services, i.e., screening program to the population.
