Zelensky addresses Western allies after Russia strikes Kyiv

Ukrainian President Volodymyr Zelensky appealed to Western allies asking them for help after Russia's most recent attack on Kyiv. "It is crucial that our forces have the necessary means to defend the country from Russian terror. I am grateful to each of our partners who help us. Timely delivery of interceptor missiles for our air defense, fulfilling agreements on defense systems, and electronic warfare production and supply are, without exaggeration, lifesaving efforts," Zelensky wrote on X. In the morning, Kyiv Mayor Vitali Klitschko reported explosions in the Ukrainian capital. A threat of a missile attack was declared in the city. It was later reported that explosions took place in Kyiv's suburbs.

Holy Martyr Mercurius of Smolensk (1238)

He was a soldier from Byzantium, one of the defenders of Smolensk when it was besieged by the Tatars in 1238. One day the Mother of God appeared to Mercurius and told him that the Tatars were preparing a surprise attack — and, further, that he must take up arms and attack the enemy singlehandedly. Placing all his trust in God, the lone soldier threw himself against the Tatar host crying 'Most Holy Mother of God, help me!' He was quickly surrounded and cut down, and it appeared that his action had been as foolhardy as it had seemed, when a woman at the head of a glorious host, all of them surrounded by light, appeared and threw back the Tatar army. The next morning the people of Smolensk found the ground covered with the bodies of their enemies. They buried Mercurius in the Cathedral, where he has been venerated as a Martyr ever since.

Gamified Cybersecurity Education Through the Lens of the Information Search Process: An Exploratory Study of Capture-the-Flag Competitions [Research-in-Progress]

Aim/Purpose. Capture the Flag (CTF) challenges are a popular form of cybersecurity education where students solve hands-on tasks in a game-like setting. These exercises provide learning experiences with various specific technologies and subjects, as well as a broader understanding of cybersecurity topics. Competitions reinforce and teach problem-solving skills that are applicable in various technical and non-technical environments outside of the competitions. Background. The Information Search Process (ISP) is a framework developed to under-stand the process by which an individual goes about studying a topic, identifying emotional ties connected to each step an individual takes. As the individual goes through the problem-solving process, there is a clear flow from uncertainty to clarity; the individual’s feelings, thoughts, and actions are all interconnected. This study aims to investigate the learning of cybersecurity concepts within the framework of the ISP, specifically in the context of CTF competitions. Methodology. A comprehensive research methodology designed to incorporate quantitative and qualitative analyses to draw the parallels between the participants’ emotional experiences and the affective dimensions of learning will be implemented to measure the three primary goals. Contribution. This study contributes significantly to the broader landscape of cybersecurity education and cognitive-emotional experiences in problem-solving. Findings. The study has three primary goals. First, we seek to enhance our under-standing of the emotional and intellectual aspects involved in problem-solving, as demonstrated by the ISP approach. Second, we aim to gain in-sights into how the presentation of CTF challenges influences the learning experience of participants. Lastly, we strive to contribute to the improvement of cybersecurity education by identifying actionable steps for more effective teaching of technical skills and approaches. Recommendations for Practitioners. Competitions reinforce and teach problem-solving skills applicable in various technical and non-technical environments outside of the competitions. Recommendations for Researchers. The Information Search Process (ISP) framework may enhance our understanding of the emotional and intellectual aspects involved in problem-solving as we study the emotional ties connected to each step an individual takes as the individual goes through the problem-solving process. Impact on Society. Our pursuit of advancing our understanding of cybersecurity education will better equip future generations with the skills and knowledge needed to ad-dress the evolving challenges of the digital landscape. This will better pre-pare them for real-world challenges. Future Research. Future studies would include the development of a cybersecurity curriculum on vulnerability exploitation and defense. It would include practice exploiting practical web and binary vulnerabilities, reverse engineering, system hardening, security operations, and understanding how they can be chained together.

Navigating the Future: Exploring AI Adoption in Chinese Higher Education Through the Lens of Diffusion Theory

Aim/Purpose: This paper aims to investigate and understand the intentions of management undergraduate students in Hangzhou, China, regarding the adoption of Artificial Intelligence (AI) technologies in their education. It addresses the need to explore the factors influencing AI adoption in the educational context and contribute to the ongoing discourse on technology integration in higher education. Background: The paper addresses the problem by conducting a comprehensive investigation into the perceptions of management undergraduate students in Hangzhou, China, regarding the adoption of AI in education. The study explores various factors, including Perceived Relative Advantage and Trialability, to shed light on the nuanced dynamics influencing AI technology adoption in the context of higher education. Methodology: The study employs a quantitative research approach, utilizing the Confirmatory Tetrad Analysis (CTA) and Partial Least Squares Structural Equation Modeling (PLS-SEM) methodologies. The research sample consists of management undergraduate students in Hangzhou, China, and the methods include data screening, principal component analysis, confirmatory tetrad analysis, and evaluation of the measurement and structural models. We used a random sampling method to distribute 420 online, self-administered questionnaires among management students aged 18 to 21 at universities in Hangzhou. Contribution: This paper explores how management students in Hangzhou, China, perceive the adoption of AI in education. It identifies factors that influence AI adoption intention. Furthermore, the study emphasizes the complex nature of technology adoption in the changing educational technology landscape. It offers a thorough comprehension of this process while challenging and expanding the existing literature by revealing the insignificant impacts of certain factors. This highlights the need for an approach to AI integration in education that is context-specific and culturally sensitive. Findings: The study highlights students’ positive attitudes toward integrating AI in educational settings. Perceived relative advantage and trialability were found to impact AI adoption intention significantly. AI adoption is influenced by social and cultural contexts rather than factors like compatibility, complexity, and observability. Peer influence, instructor guidance, and the university environment were identified as pivotal in shaping students’ attitudes toward AI technologies. Recommendations for Practitioners: To promote the use of AI among management students in Hangzhou, practitioners should highlight the benefits and the ease of testing these technologies. It is essential to create communication strategies tailored to the student’s needs, consider cultural differences, and utilize the influence of peers and instructors. Establishing a supportive environment within the university that encourages innovation through policies and regulations is vital. Additionally, it is recommended that students’ attitudes towards AI be monitored constantly, and strategies adjusted accordingly to keep up with the changing technological landscape. Recommendation for Researchers: Researchers should conduct cross-disciplinary and cross-cultural studies with qualitative and longitudinal research designs to understand factors affecting AI adoption in education. It is essential to investigate compatibility, complexity, observability, individual attitudes, prior experience, and the evolving role of peers and instructors. Impact on Society: The study’s insights into the positive attitudes of management students in Hangzhou, China, toward AI adoption in education have broader societal implications. It reflects a readiness for transformative educational experiences in a region known for technological advancements. However, the study also underscores the importance of cautious integration, considering associated risks like data privacy and biases to ensure equitable benefits and uphold educational values. Future Research: Future research should delve into AI adoption in various academic disciplines and regions, employing longitudinal designs and qualitative methods to understand cultural influences and the roles of peers and instructors. Investigating moderating factors influencing specific factors’ relationship with AI adoption intention is essential for a comprehensive understanding.

Enhancing electrospray ionization efficiency for particle transmission through an aerodynamic lens stack

This work investigates the performance of the electrospray aerosol generator at the European X-ray Free Electron Laser (EuXFEL). This generator is, together with an aerodynamic lens stack that transports the particles into the X-ray interaction vacuum chamber, the method of choice to deliver particles for single-particle coherent diffractive imaging (SPI) experiments at the EuXFEL. For these experiments to be successful, it is necessary to achieve high transmission of particles from solution into the vacuum interaction region. Particle transmission is highly dependent on efficient neutralization of the charged aerosol generated by the electrospray mechanism as well as the geometry in the vicinity of the Taylor cone. We report absolute particle transmission values for different neutralizers and geometries while keeping the conditions suitable for SPI experiments. Our findings reveal that a vacuum ultraviolet ionizer demonstrates a transmission efficiency approximately seven times greater than the soft X-ray ionizer used previously. Combined with an optimized orifice size on the counter electrode, we achieve >40% particle transmission from solution into the X-ray interaction region. These findings offer valuable insights for optimizing electrospray aerosol generator configurations and data rates for SPI experiments.

X-ray lens figure errors retrieved by deep learning from several beam intensity images

The phase problem in the context of focusing synchrotron beams with X-ray lenses is addressed. The feasibility of retrieving the surface error of a lens system by using only the intensity of the propagated beam at several distances is demonstrated. A neural network, trained with a few thousand simulations using random errors, can predict accurately the lens error profile that accounts for all aberrations. It demonstrates the feasibility of routinely measuring the aberrations induced by an X-ray lens, or another optical system, using only a few intensity images.

Test of Nikon D800e, a DX lens and a Teleconverter

I was fortunate to finally get a Nikon D800e (36 Mpx) after a brief 3 month wait. I didn't, and I also think its the same with Nikon, expect that there would be such a huge demand for this camera. I don't know why Nikon seemed to leap so far ahead with its next generation but I'm grateful. I think there are millions (well a whole bunch anyway) more who also think the same.

This is a full frame camera and a DX lens will work but is cropped due to limited image area. The camera even has mode where it will auto detect a DX lens and crop accordingly. Knowing that there is still a little more image available with the DX crop I decided not to crop and use whatever was available.

Nikon D800e with 70-200mm f2.8 VR. The image on right is actual size of window pane

My favorite DX lens is the 18-200mm f3.5 VR and as I travel around I notice others who like this lens. While it may have some pincushion and barrel distortion, thanks to Photoshop lens correction, this is almost all eliminated.
Nikon D800e with 70-200mm f2.8 VR set to 1.2 crop. The image on right is actual size of window pane. I didn't realize at first that the crop factor also applied to FX lens.

It was while I was performing a resolution test with my D300 and the new D800e by using both the 18-200mm f3.5 VR and the 70-200mm f2.8 VR that I noticed that when full zoomed on the DX lens that vignetting seemed to disappear, but looked like a dime at 18mm.

This excited me more than the current test and therefore I decided to pursue this further.

The 18-200mm is really like a 24-300mm on a DX camera due to the 1.5 crop factor and this range will meet about 90% of my needs. With a 1.4 teleconverter on the FX camera it's now almost the same range as on a DX camera.


The test I performed was hand-held as I didn't need with this test to check for perfect resolution. I stood in front of a large apartment building in the parking lot across the street and remained at the same position while I changed the lens focal length.

In the 1st test, see film strip below, there is significant vignetting in the 18mm and slowly reduces as the focal length is increased. Even at 200mm there is still slight vignetting at the corners.
When the teleconverter was added then magic seemed to appear. At 18mm there is only slight vignetting at the corners and disappears by 24mm. The film strip below shows the changes with teleconverter added.

Now a favorite lens becomes useful on my full frame camera.

Most lens that have such a wide range of focal lens is all about compromises when being designed and built. The same with the 18-200mm f3.5 VR. Photoshop easily handles the barrel distortion. But this lens at the glass edge, maybe more is being used now, also has a fair amount of chromatic appellation. This is also handled well with Photoshop. Since most artistic images don't need to be sharp or well defined at the corners of a photograph then any additional distortion caused by using more lens area is not really a problem with digital-editing.

So when and if you do decide to go full frame one day then your DX glass can be useful with a teleconverter.

The reason this works is because the lens is now further from the sensor and therefore increases in size on sensor chip. Take a magnifying glass and hold it to show an image appearing upside down on a piece of paper. Now move the magnifying glass further away and watch how the image on the paper grows larger. The same happens with a teleconverter attached.
