Impaired Sense of Agency and Associated Confidence in Psychosis
Authors: Krugwasser Amit Regev , Stern Yoni , Faivre Nathan , Harel Eiran Vadim , Salomon Roy
Published: August 2021

The Sense of Agency (SoA), our sensation of control over our actions, is a fundamental mechanism for delineating the Self from the environment and others. SoA arises from implicit processing of sensorimotor signals as well as explicit higher-level judgments. Psychosis patients suffer from difficulties in the sense of control over their actions and accurate demarcation of the Self. Moreover, it is unclear if they have metacognitive insight into their aberrant abilities. In this pre-registered study, we examined SoA and its associated confidence judgments using an embodied virtual reality paradigm in psychosis patients and controls. Our results show that psychosis patients not only have a severely reduced ability for discriminating their actions but they also do not show proper metacognitive insight into this deficit. Furthermore, an exploratory analysis revealed that the SoA capacities allow for high levels of accuracy in clinical classification of psychosis. These results indicate that SoA and its metacognition are core aspects of the psychotic state and provide possible venues for understanding the underlying mechanisms of psychosis, that may be leveraged for novel clinical purposes.
Migrant Selection and Sorting during the Great American Drought
Authors: Sichko Christopher
Published: August 2021

America's worst drought induced mass environmental migration during the 1930s. This paper studies heterogeneity in the migration response to the drought by relating migration decisions recorded in the 1940 census to county drought conditions. Drought increased migration primarily for individuals with a 12th grade education or higher because this segment of the population was less often financially constrained. In terms of destinations, drought migrants were less likely to relocate to cities compared to similar non-drought migrants. These findings document the importance of human capital for individual-level adaptation and challenge the perception that rural-to-urban is the dominant environmental-migrant channel.

Since the fall of 2003 the Louisiana Aerospace Catalyst Experiences for Students (LaACES) program has been providing university students a two semester project that culminates with the flight of a scientific balloon experiment. During the first semester students complete the Student Ballooning Course (SBC) which teaches basic skills necessary to develop a working scientific payload. The SBC consists of a series of lectures and activities providing instruction in electronics, programming, project management, balloon payload design, and introductory circuit assembly. The SBC introduces the BalloonSat, a sub-assembly designed at LSU for LaACES which contains a microcontroller, real-time clock and a four channel analog-to-digital converter. The second semester is spent on the design, development, testing and calibration of the payloads. Upon completion of the Flight Readiness Review, students travel to the NASA Columbia Scientific Balloon Facility (CSBF) in Palestine, Texas for integration, launch, recovery and science presentations. A flight capable Automatic Packet Reporting System (APRS) radio beacon armed with GPS and command capable cut down was developed to track the balloon during flight and to cut-down the payloads. Tracking vehicles are outfitted with radios tuned to APRS frequency and laptops displaying maps of the payload location. Here we describe LaACES; program development, tools and technologies, implementation, program, management issues and flight experiences.

An educational paradigm that has improved problem-solving capacity is computational thinking, which uses characteristics such as decomposition, abstraction, pattern recognition, and algorithmic thinking. However, most of the resources developed under this paradigm are deterministic. However, the current world is not linear. Non-deterministic dynamics play a vital role in today's world. Decisions about the same fact can cause different events, and students must be prepared to live with such uncertainties. This article discusses challenges and possibilities in the development of non-deterministic computational thinking resources. This work shows a large field of research yet to be worked on, with new possibilities and a great potential to connect new resources with the students' daily lives.

Published: August 2021

BACKGROUND

Extracranial arteriovenous malformations (AVMs) are rare clinical entities and on rare occasions cause neurological symptoms. The authors report a case of an extracranial pterygoid AVM and a subsequent contralateral cavernous sinus dural arteriovenous fistula (dAVF) presenting with abducens nerve palsy.

OBSERVATIONS

An 80-year-old woman was referred to the authors’ hospital with left abducens nerve palsy followed by right ophthalmalgia. Magnetic resonance imaging (MRI) showed abnormal vessel staining in the left pterygoid and the right inferior petrosal sinus (IPS). Cerebral angiography revealed a left pterygoid AVM draining into the right IPS via the cavernous sinus (CS). A dAVF in the right CS was also revealed. The right ophthalmalgia disappeared spontaneously, and, 4 months later, the left abducens nerve palsy also disappeared after conservative management. Follow-up MRI showed spontaneous regression of the AVM and dAVF. The disappearance of the dAVF was considered to be due to spontaneous regression of the left pterygoid AVM and the consequent decrease in venous pressure of the CS, and the symptoms eventually disappeared.

LESSONS

The authors treated an extremely rare case of extracranial AVM with dramatic changes in vascular structure and symptoms. Understanding of the pathophysiology between symptoms and dynamic changes in the vascular structure is essential for providing the appropriate treatment.
A Rare Case of an Ascending Aorta and Aortic Arch Aneurysm with an Aberrant Right Common Carotid Artery
Authors: Olalo Mikhail M. , Guillermo Syril Bren P.
Published: August 2021

Ascending aortic aneurysms are asymptomatic and are usually discovered as an incidental finding on chest imaging. However, larger aneurysms can present with symptoms resulting from compression of surrounding structures including the trachea, bronchi, and the esophagus which can result in hoarseness, cough chest pain or back pain. The presence of an aortic arch anomaly, specifically an aberrant right common carotid artery, in a background of an aortic arch aneurysm is extremely rare with a worldwide incidence of <1%. They are usually asymptomatic but can result to catastrophic life threatening events and pose significant challenges to surgical or endovascular treatment. This is a case of a 63-year old Filipino male who presented with a sudden onset of dull back pain radiating to the left anterior chest. Workup revealed an ascending and aortic arch aneurysm with an aberrant right common carotid artery arising directly from the transverse aorta. Surgical aortic arch debranching was done to repair the aberrant vessels prior to Thoracic Endovascular Aortic Repair (TEVAR) wherein a custom-made Thoracic Valiant graft was deployed on the aneurysm. The patient was discharged on the 4th day after TEVAR without any complaints of dyspnea, back pain nor chest pain with no neurologic and visceral organ dysfunction. This case has emphasized that knowledge on the anatomy of the aortic arch is imperative in planning out thoracic surgery and endovascular interventions especially on rare anatomic anomalies such as seen in this case.

Authors: HATİPOĞLU Durmuş , KAHRAMAN Okan
Published: August 2021

An adult dog were evaluated for treatment loss of consciousness, convulsions, and severe tremors after ingestion of xylitol, a sugar alcohol used as a sweetener in various products. Clinical findings were noted as loss of consciousness, convulsions, and severe tremors, while physio-pathological findings included moderately to severely elevated serum activities of liver enzymes, hypoglycaemia and hypophosphatemia. To correct hypoglycaemia, dextrose was administered intravenously and to provide electrolyte homeostasis Izolen P was administered intravenously. Also, Milk Thistle (Silymarin) & Beta Glucan Complex, Hepatiale Forte Advanced (S-adenosylmethionine), Evicap (Vit E) and Asist (acetylcysteine) were used to correct acute liver damage. Values measured after the applied treatments showed that blood glucose levels and liver enzymes returned to normal, and the patient was discharged. Xylitol causes hypoglycaemia and acute liver damage in dogs after ingestion. As a growing number of products contain xylitol, clinicians should be aware that ingestion of xylitol could have life-threatening effects. This case report also carries the distinction of being the first xylitol toxicity reported in dogs in Turkey.

The mechanical behaviour of auxetic materials and structures is the most distinctive characteristic, which differs from that of conventional engineering materials due to the negative Poisson’s ratio. Auxetic materials have the fascinating feature of widening when stretched and contracting when compressed. In recent times, the research of auxetic materials based on textile structures has received a lot of interest. Auxetic effect development at the yarn phase is a new and exciting field of study. Many researchers already developed different types of auxetic yarns, such as the helical auxetic yarn, the plied auxetic yarn, the semi-auxetic yarn etc. The helical auxetic yarn (HAY) is the most commonly mentioned auxetic yarn. It is made up of a rigid wrap and an elastic core yarn. However, it is interesting that auxetic yarns can be produced from conventional non-auxetic fibres through the conventional spinning system as well. The helical auxetic yarn is a new type of yarn with a wide variety of possible applications. Moreover, pore-opening characteristics of auxetic yarns make it a potential candidate in the fields of technical textiles, such as medical textiles, filter application, protective textiles etc. Fabrication of auxetic textiles by utilizing auxetic yarns through simple weaving and knitting technology opens the door to new applications. The aim of this paper is to address the fundamentals of auxetic yarns, such as structure, shortcomings, production techniques, as well as the influencing process parameters. From various research works, it is evident that the wrap helical angle, the core/wrap diameter ratio, and the initial moduli of wrap component are the most vital processing parameters during the production of auxetic yarns. Finally, some potential application areas and challenges of auxetic yarns are also addressed briefly in this paper.

Published: August 2021

Among the different types of shredding equipment, which is widely used in various industries of Ukraine, the most promising are machines with complex spatial movement of working tanks. Experimental studies of the movement of the bulk array in the middle of the working tank with transparent walls were performed. The positions of the moving links and the working capacity are set, at which the whole bulk array by its mass will create the greatest value of the static moment of resistance on the driving shaft of the machine. Analytical studies of the static moment of resistance formed on the drive shaft of the machine with complex spatial motion of the working tank as a result of the influence of gravity acting on the bulk array loaded into the tank, the corresponding mathematical dependences are obtained. The obtained research results will be useful in further determining the dynamic moment of resistance on the drive shaft, which will be created by moving the moving parts of the machine and the bulk array in the middle of the tank. Also, the results of research can be used by relevant machine-building enterprises at the stage of designing galvanizing types of equipment with tanks that perform complex spatial movement.

Nowadays, there is an increase in the installed capacity of solar (mainly) and wind energy, which requires additional balancing reserves and requires the improvement of existing and development of new balancing methods. If at the end of 2018 the total capacity of PV and WPP was 1.7 GW (excluding the occupied territories), then at the end of 2020 it increased to 8 GW (including PV of households). Thus, the simultaneous influence of two reinforcing factors affected – a decrease in available control volumes at TPPs and an increase in the need for shunting generation due to increasing uneven daily consumption schedule and increasing volumes of stochastic generation from RES, namely unsecured power stations – PV and WPP. As a result, this created a problem of shortage of shunting generation and led to the need to build new high-shunting capacity, such as using hydrogen technology. Therefore, the article analyzes the problems of electricity that can be solved through the use of hydrogen technologies. The preconditions of occurrence of these problems are investigated and the ways of their overcoming are offered. Many developed countries, such as the United States and China, have a positive experience of using hydrogen technology as a source of electricity. Ukraine has adopted a Roadmap for the development of hydrogen energy for the period up to 2035 to ensure the use of hydrogen as an environmentally friendly energy source. Therefore, the article discusses in detail the methods of obtaining hydrogen fuel. The variety of methods for producing hydrogen is one of the main advantages of hydrogen energy, as it increases energy security and reduces dependence on certain types of raw materials. These include: steam conversion of methane and natural gas, coal gasification, water electrolysis, pyrolysis, partial oxidation, biotechnology. The article proposes a schematic diagram of a combined power plant of low power, containing a battery of fuel cells, wind turbine, cell, receiver. This installation can be used as an autonomous power source.

The problem of unification of forms of technical description by grouping of types of clothes by functional purpose is investigated. An empirically substantiated empirical database of technical description for the analysis of the optimal version of the control information about the conformity of the sample-reference. Intertype unification is used in nodes not subordinated to the main size: overlays, pockets, collars, cuffs. The pockets are not subject to the size of the unified structural basis, so they are grouped into a module of types of pockets. The mechanism of detection of discrepancies in control measurements of models of a product between standard unified constructive bases and details of models of pockets is offered. The main feature of the basic unified structures is that when changing the design increase, the lengths of the sections change only at the level of the armhole, waist and bottom (files and backs). The lengths of the remaining segments remain constant. The basic bases of the pants design have a constant value of balance and a constant position of the horizontal design lines (waist, hips, knees, bottom). The choice of design and technological solutions given in the technical description on the model of trousers and overalls is made. A matrix of combinations of technical information for control of constant data in a group document is proposed. The module of sorting of forms of the technical description of foreign firms for fixing of unification of constructive and technological parameters of performance of the basic knots of a product is developed. The use in the forms of technical documentation of gradation of the level of quality on the basis of homogeneity of manufacturing technology is based on imitation of the general constructive elements. The results of the calculation of the repetition rate for waistwear confirm the homogeneity of the modifications and the affiliation of units that are not subject to the main size to the design document of the group.

In the world and in Ukraine, the quinoa market is growing rapidly due to its extremely beneficial properties for the body. Quinoa is one of the few gluten-free crops with a high content of easily soluble proteins, which provides the possibility of making special foods for children, people who play sports, vegetarians and diabetics. Quinoa grain contains a lot of protein: from 16.2% to 20%, the amino acid composition of the protein is very balanced, quinoa grain also contains carbohydrates, fats high in lecithic acid, fiber, minerals and vitamins of group B. The dynamics of sown areas and quinoa production in the world. The work is devoted to the organization of the operation of purification of quinoa grain, which is an important stage of its post-harvest processing. Any processing of grain is associated with its purification from impurities. The presence of impurities negatively affects the efficiency of grain storage and its technological features, which leads to a decrease in yield and quality of processed products. Therefore, cleaning operations occupy a central place in the post-harvest processing of grain. We have determined the geometric dimensions and calculated the basic geometric parameters of quinoa grain, which are the main indicators for the organization and conduct of the cleaning process. To identify the necessary working bodies and determine the optimal size of the holes for the separation of the mixture into fractions, the analysis of the variability of the grain size of the main crop and the size of the released impurity. Based on these data, a correlation table is constructed. Analysis of the correlation table shows that for effective cleaning of quinoa grain it is necessary to use sieves with a diameter of 3… 3.5 mm to remove large impurities and sieves 1.0×20, with a diameter of 1.6 and 1.8 mm. Based on the data of the correlation table, a fractional scheme of quinoa grain purification was developed, with the appropriate shapes and sizes of sieve holes. This scheme of purification of quinoa grain is effective and allows to isolate 93% of impurities.

Improving the process of knitting fabrics from Kevlar complex threads on flat knitting machines is to create the minimum necessary tension in the area of formation of the knitted fabric. To ensure this, it is necessary to determine the change in relative tension in the refueling zones of Kevlar complex threads on flat knitting machines. These zones are formed by arranging the thread guides, tension compensation devices, tension devices and thread break control devices in the working area of the supply system to form a spatial filling line for each specific knitting machine. This complex task for flat knitting machines should be based on the use of specially designed computer programs. Given the specifics of processing Kevlar complex threads on flat knitting machines, when determining the relative tension in each zone, it is necessary to use a recursion algorithm, when the output tension of Kevlar complex threads from the previous zone will be the input for the next zone. When determining the tension of Kevlar complex threads, their interaction with the guides of Kevlar complex threads, tension compensation devices, tension devices and devices for controlling the breakage of Kevlar complex threads, it is necessary to take into account the value of Kevlar complex thread diameter, its physical and mechanical properties, deformation, deformation the coefficient of bending stiffness when determining the actual angle of coverage of the guide surface. Ensuring the minimum necessary tension in the area of formation of the knitted fabric will allow to obtain the parameters of the loop structure of property and tactical equipment of servicemen capable of protecting the human body from fire, cold, cutting, barbed weapons, shock and shotgun impact. Minimizing the tension in each zone of the line of Kevlar complex threads on flat knitting machines will reduce the probability of breakage, which is important for improving knitting processes from the standpoint of improving the productivity of flat knitting machines and product quality. Mathematical support of a computer program requires the development of models of thread guides, tension compensation devices, tension devices and thread break control devices, taking into account the real physical and mechanical properties of Kevlar complex threads and real geometric and structural parameters of structural elements of the feed system.

The device for measuring humidity with a moisture-sensitive resistive element HR202 has been developed. The self-generating transducer is designed as a hybrid integrated circuit based on a bipolar transistor VT1 and a field-effect two-gate transistor VT2. The negative differential resistance, which is formed by the parallel connection of the impedance with a capacitive component at the collector electrodes of the bipolar transistor VT1, the drain of the field-effect transistor VT2 and inductance L1, leads to the occurrence of electrical oscillations in the circuit. When exposed to moisture on the sensitive resistive element RW, the capacitive component of the impedance at the electrodes of the transistor structure changes, which causes an effective change in the frequency of the oscillatory circuit. On the basis of mathematical modeling of electrical characteristics, analytical expressions for the transformation function and the sensitivity equation are obtained. It has been experimentally established that an increase in the ambient temperature in the range of relative humidity W = 30 ÷ 85% leads to an expansion of the generation range of the autogenerating humidity transducer, as well as to an increase in the sensitivity of the device to the measured value. The generation range of the autogenerating humidity transducer at a temperature of T = 20 °C acquires a value of 823 kHz (the average value of the sensitivity is 16.18 kHz /%), and at a temperature of T = 50 °C – 1323 kHz (the average value of the sensitivity is 29.10 kHz / %). To confirm the theoretical results of circuit solutions developed device in the computer modeling of LTSpice modeling environment. The studies were carried out at different temperatures (20°C, 30°C, 40°C, 50°C) in the range of change in the resistance of the moisture-sensitive resistive element from 1750 kOhm to 2.1 kOhm, which corresponds to an increase in the value of the relative air humidity from 30 % to 90 %. The results of theoretical and experimental studies have shown that at the output there are periodic oscillations device for measuring the humidity rate which increases with increasing values ​​of relative humidity. The obtained theoretical and experimental studies are in good agreement, the relative error does not exceed 2.5%.

To date, pneumonia is one of the most common and severe lung diseases in the world. Early diagnosis of pneumonia is a crucial factor in its successful treatment. Over the last decade, automated analysis of chest X-rays has been recognized as an effective tool for diagnosing lung diseases. However, the problem of implementing and configuring methods that explain the results of digital diagnosis remains acute. Convolutional neural networks now show state-of-the-art results in the identification of diseases on X-ray. Therefore, to address the urgent issue in digital diagnosis, we propose information technology for visual analysis of X-ray images to explain the results of diagnosing pneumonia. The technology comprises a classification model based on a convolutional neural network to remove mild features of early viral pneumonia and a modified method of different localization to interpret the classification results. The method of interpretation is to apply weighted gradients to class activation maps. It distinguishes lung masks in the X-ray image and imposes thermal maps with a color gradient from blue to bright red. The red color corresponds to the most probable location of the pneumonia features in the radiograph. Such a modification provides excellent localization of abnormal areas on radiographs, removing the mild target features of early pneumonia. It should be noted that our model based on the convolutional network surpassed other classifiers in precision (98.5%) but slightly conceded in classification accuracy (96.1%) and recall (93.6%). Also, it shows relatively low false positive and false negative rates, with 1.4% and 6.4%, respectively. Overall, according to computational experiments, the proposed information technology can be an effective tool for instant diagnosis in the first suspicion of pneumonia.
