“The Use of Galilean Geometry, Magnetic Fields and Late Heating with a Laser to Achieve Conditions for Ignition of Nuclear Fusion using a Confinement Approach.”
By 2050, the world will consume 2-3 times more energy than it does today. What’s more, existing energy sources such as coal and fuel will be depleted across the globe. Nuclear fusion is poised to resolve this issue, as it is a highly efficient approach, its energy sources are renewable, and it is even environmentally-friendly. Will the use of cylindrical geometry, magnetic fields and late heating using a laser enable the achievement of conditions for the ignition of nuclear fusion using an inertial confinement approach under similar or more lenient conditions than spherical geometry? For a nuclear fusion system in an adiabatic state that takes into account Bremsstrahlung radiation and heat conduction, an output equation was developed - one that expands to that state within which the magnetic field exists. In this study, we examined the cylindrical approach, with a focus on which conditions it prefers in relation to the spherical approach. It was found that there is achievable value in a magnetic field capable of bringing the system to the necessary ignition conditions.

“The Effect of Pro Apoptotic Protein ARTS on the Death of Stem Cells in the Intestine Following Radiation.”
Apoptosis is a type of programmed cellular death (PCD) that takes place within the cell. It is a self-destruction mechanism that the cell enacts by activating several factors, under scrupulous supervision. It was found that the ARTS protein, found only in stem cells - cells with unlimited differentiation potential, encourages apoptosis. This study examined how a lack of the ARTS protein might influence the cellular death of stem cells in the intestine following radiation, as their purpose is to lead the cell to apoptosis. The experimental group included mice lacking the coded gene for the ARTS protein, while the control group consisted of regular mice. In both groups, stem cells and their daughter cells were marked, for monitoring purposes. The results showed that, following radiation, the mice lacking the ARTS protein exhibited significant increases in stem cells and supporting cells. What’s more, their intestines were healthier and better developed. The lack of the ARTS protein evidenced that there is better renewal, in the form of more daughter cells and increased differentiation of the stem cells. In addition, we observed a new phenomenon of additional stem cell population creation in uncharacteristic locations. The study’s findings contribute to a better understanding of the cellular death of stem cells in the intestine, as well as of the role of the ARTS protein. These findings serve as the foundation for the development of medications to inhibit the ARTS protein in human beings. Such a medication could lead to the intestine’s recovery and renewal in pathological states, such as Irritable Bowel Syndrome (IBD) and Cancer.
Second place was awarded to:

“Artificial Intelligence Simulation for the Coordination between Bots in Motion in Space Using Social Selection Theory.”
In this study, we developed a simulation that illustrates chases after targets in space, and coordinates between the autonomous agents running after a particular target. We asked - what scenario requires a minimal amount of steps before one of the agents reaches their target. During each stage of the simulation, we decided where each of the agents would be in the following stage. These decisions were sent to a control center, which tabulated a collective decision - the one that was ultimately enacted. The simulation was ended when the target was found by one of the agents. The agents and the control center had several possible courses of action and various integrations of these courses of action they could implement. Our findings prove that the most effective approach is bringing the closest agent to the target - to the target, and randomly moving the others about, while integrating the control center’s tabulations, based on the most certain decision of all the decisions reached by the various agents. These results prove that the most effective form of coordination is focusing on a single potential point between the symptoms, one that focuses on a certain location. This is more effective than coordination that spreads over a number of potential points. These results can be used in the future to make it more efficient for people to reach targets in space, like in the case of traveling via ambulance to treat injured people, coordinating between drones meant to locate drowning victims in the sea, etc.

“The Role of Parasites in T-A (Telangiectasis) Disease.”
Ataxia Telangiectasia is a genetic disease caused by damage to the ATM gene characterized by motor impairments sourced in the neurodegeneration of the cerebellum. Parasites are cells found around blood vessels. One of their roles is to maintain the blood vessels’ and Blood-Brain Barrier’s impermeability. We hypothesized that, with T-A, the parasites are harmed, causing an abnormal network of blood vessels, which leak and lead to neurodegeneration in the cerebellum.
In order to mimic the distribution of parasites throughout various regions of the cerebellum in laboratory mice with T-A, mice with fluorescent parasite markers were selected, and they were tested to determine how many parasites were present, and over which areas they were distributed. We found a significant decrease in the parasites’ distribution space in the model mice with T-A in both layers of the cerebellum, while the decrease in the number of parasites only decreased in the cerebellum’s granular layer. These findings serve as further proof of damage to the blood vessels in T-A patients, contributes to deeper understanding of the mechanism of this damage, and opens the doors towards future studies on this subject.

“The E12 Antibody’s Effect on Intracellular Activity in T+CD4 Cells and Macrophage Cells.”
Multiple Sclerosis (MS) is a severe autoimmune disorder that attacks the body’s central nervous system. The E12 antibody, developed in the laboratory of Professor Natan Karine, links to immune cells (T and Macrophage cells) and transforms them from inflammatory cells (cells that encourage inflammation), involved in the development and deterioration of MS, into anti-inflammatory cells (cells that reign in the inflammation process). The goal of our study was to understand the intercellular action mechanism of the E12 antibody on T and Macrophage cells, with a focus on known phosphorylation trajectories. To do so, the Macrophage cells from mice’s stem cells and JURKUTS cells (a string of T cells from human sources) were defined in the presence and in the absence of the antibody. Phosphorylation levels were measured for ERK, STATS and MEK proteins. In addition, in order to examine whether the antibody is involved in the phosphorylation trajectory of other proteins, a Full Moon study was conducted on T cells sourced in the mice’s spleens, with and without the stimulation of the E12 antibody. It was found that the antibody is involved in the phosphorylation trajectories of various proteins, one being the activation trajectory of the STAT6 protein. Phosphorylation of the protein plays an important role in the release of cytokine IL-4, which is involved in the reduction of inflammation following infection, allergy or other autoimmune responses. Understanding the activation trajectories of these proteins will help our understanding of how the E12 antibody can serve as a potential medication and help mitigate the severity of autoimmune disorders, such as MS.

“The Effect of Biological Clocks on the Penetration of the Blood-Brain Barrier, with a Focus on T Proteins.”
Various organisms have their own circadian rhythms/clocks, which regulate various processes according to 24-hour daily cycles. A connection between damage to biological rhythms and neural pathogens has been identified, (for example) as a result of hyper penetration of the selective Blood-Brain Barrier (BBB), which is not supposed to allow diffuse passage to substances through brain tissue (including medications destined for the brain), in order to maintain the stable environment critical to its functioning. This selection is enabled, in part, by Tight Junctions (TJ), which include proteins that affix the endothelial cells within the capillaries, including the ZO-1 and claudin-5 proteins. The goal of our study was to examine whether there is a change in the expression of coded genes for these proteins within the BBB of wild mice, at different times of the day - 8 AM and 8 PM. Our findings demonstrated that, with respect to the expression of claudin-5, there was a decrease between the morning and evening measurements, while the opposite was expressed with respect to ZO-1. The study, therefore, serves as the foundation for future studies on the mechanism within which this change takes place, in order to more efficiently time medication dosing for neural diseases, based on the understanding of this mechanism.

“Mapping the site of Ligand Connections for the Creation of Specific Connections between Proteins.”
The connection between proteins depends on the location of certain amino acids at the site of the connection, so that any change (mutation) within any one of them could potentially affect the properties of the connection. In this study, we developed an approach that quantifies the effect of these mutations on the protein’s connections, in order to create selective connections. The N-TIMP2 inhibitor was selected as a case study, and we built a genetic library containing a specific mutation at main positions within its connection interface. In addition, three proteins were selected for comparison purposes - 1,3,14 (MMP). The MMP proteins were defined with mutated inhibitors and sorted into subpopulations according to the force of their connections. Each inhibitor containing a mutation on one of its selected posts also received a score using the NF (normalized frequency) method, which was developed in order to calculate mutations’ affinities and selectivities. Hot/cold spots were found along the N-TIMP2’s genetic spectrum, as well as mutations with specific connections for each of the MMP proteins. This could potentially lead to the development of specific inhibitors for MMPs with cancer-like characteristics. Specific connections between proteins are motivators of biological responses in the body. It is possible that leveraging this method will enable the development of highly-targeted medications that act upon selected proteins, causing minimum side effects.

“Discovering the Mapping for Triatomic Molecules.”
A Colombe explosion is one of the techniques used to research chemical responses at an atomical level, as it enables us to view the dynamics of a structure as it breaks down and creates chemical connections. In 2018, it was theoretically proven that the explosion of triatomic molecules of various geometric proportions lead to the same sort of explosion. This study focused on the discovery of the conditions for which the mapping of a tri-atomic molecule via Colombe explosion is unique. For this purpose, we used hyperspherical coordinates to describe the initial geometry of the molecule, as well as the Dalitz plot to describe the speed of the three pieces of the Colombe explosion. We examined which initial geometries have a similar Colombe explosion result, and which do not. After replicating the results from the existing literature with respect to exploding a triatomic (identical) system, we found that when the atoms have different masses, most geometries can obtain unique mapping. This result enables us to expand our use of the Colombe explosion method from a di-atomic molecule to a triatomic molecule.
We are proud to congratulate our students who, yet again, honorably represented us at the 2019 Young Scientists & Developers Competition in Israel.

Examination of the Impact of the E12 Antibody on the Creation of Memory Cells within the Immune System and its Ability to Cope with Disease
Multiple Sclerosis is an autoimmune disease that causes immune system cells to attack neurons in the brain. The disease’s symptoms, as well as the damage to the cells themselves, come in “attack waves,” between which there are periods of relief. The immune system leaves memory cells in the body, which respond to the disease faster during experiences of secondary exposure, and help the body cope better. Regulatory Type 1 (TR1) T cells are a type of immune cell charged with controlling the immune response and preventing the immune system from attacking the body. Previous studies found that the E12 antibody inhibits the deterioration of Multiple Sclerosis by causing T cells to be differentiated as TR1 calls. Our study examined whether the cells induced by the E12 antibody would become memory cells capable of helping the body cope with the disease’s repeat attacks. Lab mice with Multiple Sclerosis were split up into several control groups, as well as a group that was treated with E12. We followed the development of the disease’s symptoms, and the TR1 cells themselves. The mice treated with the E12 exhibited reduced symptoms of the disease, as well as an increase in the relative amount of memory cells in their spinal cords. As such, it is evident that E12 causes T cells to differentiate into memory cells capable of suppressing future attacks. This discovery can serve as the foundation for future development of new medical protocols for Multiple Sclerosis.

Is Awareness A Requirement for the Execution of Semantic Integration?
At any given moment, we engage in many integration processes. For example, if we see a person jump out of a plane with a sofa (as opposed to a parachute), we’d most likely think that we were witnessing a strange event. Why? Because, from a semantic perspective, skydiving and sofas are unrelated - a conclusion we reach thanks to a process called semantic integration. With respect to the study of awareness, a relevant question is whether one can perform or execute semantic integration without being aware of it and, if so - to what degree? The theories are divided - some claim that one cannot perform integrations in general, or semantic integration without awareness (such as the IIT and GNW theories), while others posit that it is possible (such as the YIC theory). In this study, we tried to answer the question of whether one can perform semantic integration without awareness. Namely, can our brain “understand” that there’s something strange about an image of a person skydiving with a sofa, without being aware of the image itself? For this purpose, participants viewed “ordinary” images (skydiving with a parachute) and “strange” images (skydiving with a sofa). The images were presented in a way that the participants were not aware of them, and it was examined whether there was a difference between their brain activity after viewing the “ordinary” image versus after viewing the “strange” image. No significant difference was found between the two types of images, strengthening the claim that awareness is needed in order to perform semantic integration.

Three-dimensional Representations of Cosmological Simulations
The analysis of galaxy simulations is a central part of cosmology research. Often, the researcher is faced with the challenge of understanding the data they are working with. This stems from the fact that the simulations are three-dimensional in nature, and do not make it easy for the researcher to understand the details of the simulation.
Throughout the course of our research, we developed the necessary tool, which we named VIVID. This tool enables the interactive observation of simulations in three dimensions. To resolve the issue pertaining to the visualization of relevant information, we used a Voronoi algorithm for the three-dimensional space. In this way, we were able to convert the simulation’s data (a point-cloud structure in standard simulations) for the body, formed of polygons and dots, which enables deeper understanding of the simulation and its shape in the three-dimensional space. VIVID was developed with two underlying principles in mind: (1) simplicity - it is up to the researcher to perform a minimum number of actions; (2) efficiency - the code should execute the task in the most efficient way.
While the code has yet to be finalized, we already used it to generate several models. Researchers at the Rokach Institute for Astrophysics experimented with these models and found that our three-dimensional result most certainly helps with understanding simulations, and even enables the identification of physical phenomena that cannot be discerned in two-dimensional representations.

The Use of HL60 Cells as a Model System for the Research of Human Neutrophils
Neutrophils are the most common type of immune system cells found in the bloodstream, which are capable of killing pathogens by secreting hydrogen peroxide during the oxidative burst process. Since these cells are extremely short-lived, they cannot be grown into a culture and they are hard to manipulate genetically. The HL60 cell line is an immature leukemic cell line that is capable of differentiating into cells that are “like” neutrophils, basophils and monocytes. The goal of this study was to examine the possibility of using HL60 cells as a model system for researching human neutrophils. First, we examined the shape of the HL60 cells’ nuclei throughout the differentiation process and found that it matches the shape of the nucleus that presents in human neutrophils. We later examined the presence of the CD668 receptor, which serves as a specific indicator of mature human neutrophils and found that it is not expressed in HL60 cells, seemingly because they are cancerous cells. In addition, we found that the occurrence of the oxidative burst process and the functioning of CYBB, CYBA and NCF2 proteins are similar to those of differentiated HL60 cells and human neutrophils. The results demonstrate that HL60 cells are capable of serving as a reliable model for the research of human neutrophils.

Producing Chords for Music using Machine Learning Algorithms
In music in general and in modern music in particular, chords serve as an essential part of the composition, and often even define the composition itself. That being said, writing the chords for music is a complex process that requires experience, intuition and time. Our research realized algorithms that automatically compose chords for music: Taking the notes into account (as a function of time), the algorithm composes chords (as a function of time), using machine learning. We compared them according to different variables and studied whether the chords produced by one of the sets is more pleasing to the human ear than those chords that were in the original composition.
Throughout the course of the study, we found that the Random Forest algorithm is preferred over the others examined (Support Vector Machine, Decision Trees, Gaussian, Naive Bayes), due to its ability to produce chords that most closely resemble the original ones.
Surprisingly, we showed how the process was successful, even if the algorithm is not exposed to information on the length of time relevant to the chords, but rather only about which chords appeared in each bar. In addition, only a relatively small amount of musical compositions is needed to complete the “training process.” And, even though the algorithm does make mistakes, the sample study we performed evidenced that people do not have a preference for the computerized chords over the original ones, except for in the case of certain songs. We hope that this study will enable new cooperations between man and computer in the field of music.

The Influence of the Propaganda Dichotomy on the Success of Hitler’s Propaganda and Image
Hitler, the all-powerful leader of Nazi Germany from 1933-1945 did not grow his public image overnight. Rather, his image developed over time, using deeply considered propaganda. This propaganda presented Hitler in the following ways: various posters portrayed Hitler the strong leader who elevated the German nation, but other posters presented him as a man of the people; accessible and altruistic, who fights on behalf of the nation he belongs to. There were billboards that presented Hitler as the successor of Germany’s previous fearless leaders, while others depicted Hitler as a revolutionary charged with destroying Germany as it was - a country that was eviscerated and had to sign a humiliating declaration of capitulation following the First World War. This evidences the existence of contradictions within the various representations of Hitler and Nazi propaganda. These contradictions are surprising, especially when considering the words of Joseph Goebbles, the Nazi Propaganda Minister, who claimed that effective propaganda repeats the same messages over and over again. If so, why do these contradictions exist? This study claims that the contradictions existed in order to help the German public identify with Hitler’s methods. In this way, the people were able to differentiate from one another, yet still connect to Hitler’s personality and facets, as presented in the propaganda. This propaganda transformed Hirler’s image into a dynamic personality that won the support of the German nation. Unlike other studies that presented the different aspects of Nazi propaganda, this study focused on the connections and contrasts between these aspects, as well as their contribution to the propaganda’s success.

A New Experimental Approach to Researching the Metasomatism of Peridotites within the Earth’s Mantle
The earth’s mantle is home to chemical reactions between rocks, which change the mineral composition (a metasomatic process) and influence a variety of geological phenomena. The goal of this study was to understand the results of the response between two mantle rocks under conditions of high pressure and temperature (1200 degrees Celsius, 4GPA), which simulate the conditions that exist at a depth of 120 kilometers. We examined the interaction between two mantle rocks: eclogites and peridotites. For the purpose of this study, we used a tool that simulates conditions of mixing that take place within the earth’s mantle at an inverse frequency of 15 minutes to enable maximum interaction. The results of this interaction were attributed by means of a laser tool and scanning electron microscope. The study found that the eclogite slice responded with the peridotite rock to create new minerale phases and a slice that is rich in magnesium, silica, potassium and water. The composition of this new slice was similar to that of Kimberlite Type 2 - a rock that emanates from the depth of the mantle and can contain diamonds. This simple study therefore sheds new light upon the creation of rocks within the earth’s mantle.

Three-dimensional Printing of Hydrogels Using A Combination of Nano-cellulose Particles
DIW is a printing technique based on the injection of ink layers on top of one another, on a moving surface, in line with the computerised three-dimensional model. The printing of hydrogel, a polymer than expands in water, is limited as the injected ink must stabilize satisfactorily as soon as it exits the syringe, and quickly become fixed in order to serve as the foundation for the next, incoming layer of ink. This study presents a solution to the aforementioned problem by combining nano-cellulose particles with the photoinitiator molecules found in the ink. The nano-cellulose particles provide the ink with low levels of viscosity while flowing, so that it can easily exit the printhead and harden on the printer’s surface. The photoinitiator can then use a radical polymer to affix each layer, under conditions of illumination. In addition, this study presents an examination of the ink’s properties and its ability to soak up the water, as well as the mechanical properties of the printed entities. These findings evidence the practicality of hydrogel printing that polymerizes via illumination using DIW printing, ahead of its integration in future systems.

The Lack of Angular Uniformity in the Influence of TAS2 Magnetic Fields
Van der Waals superconductors are materials composed of flattened atomic levels linked between themselves via Van der Waal connections. These materials have unique components such as, a significant lack of symmetry between the resting direction and the direction parallel to the atomic layers, as well as the behavior of the superconductor under low temperature conditions. In this study, I examined the influence of the magnetic field and its direction on the superconductor, and the energy gap of the tantalum disulfide type of Van der Waal material. I found that the superconductor responds in a significantly anisotropic manner with respect to the magnetic field, and its superconductivity survived within a magnetic field that was 20 times stronger in the direction that was parallel to the material, than in the perpendicular direction. I then calculated the distance between electron pairs within the material and demonstrated that one can derive that superconductivity within the substance is three-dimensional, so that a charge can be transmitted between its layers. These results expand our understanding of the superconductivity phenomenon and could possibly pave the way towards developments based on the aforesaid phenomenon, such as trains that hover over superconductor tracks.
