description: The present research was to investigate the effects of skimmianine (SK) in four non-small cell lung cancer (NSCLC) cells. We found that SK can significantly inhibit the growth of NSCLC cells and markedly induce apoptosis in NSCLC cells. The effects of growth inhibition and apoptosis induction were in a concentration–response relationship and caspase-dependent manner.

description: "True knowledge lies at the dead pile." First heard from Dr. Eugene Janzen, but likely quoted many times by cattle veterinarians! The digital revolution provides new tools with the potential to change how necropsies are conducted; however, these tools' validity must be tested. As a project of Merck Animal Health, a mobile and web-based application was designed to systematically collect digital necropsy images, making them available to diagnosticians. DVMDx is based on proprietary digital and web-based diagnostic systems used for 20 years by Feedlot Health Management Services Ltd. To validate this system, trained veterinary students followed a prescribed digital necropsy protocol on 192 cattle from feedlots and calf ranches with clinical respiratory disease. In parallel, tissues samples were submitted to a diagnostic laboratory for histopathological and microbiological evaluation. Veterinarians experienced in interpreting digital images provided a single "most likely” syndromic diagnosis which was compared to laboratory and microscopic findings. An antemortem diagnosis of respiratory disease was confirmed by gross image analysis in 90%, and by laboratory testing in 94%, of the cases. Digital and laboratory diagnoses agreed in 79% of the cases when the primary diagnoses were compared, and 88% when all diagnoses were compared. When the syndromic diagnosis predicted the etiology based on digital images, Histophilus somni and Mycoplasma bovis were confirmed in 25% and 100% of the cases, respectively. These data support the further refinement of this tool, which has the potential to significantly increase the number of animals receiving cost-effective and diagnostic postmortem inspections.

description: We compare quantum dynamics in the presence of Markovian dephasing for a particle hopping on a chain and for an Ising domain wall whose motion leaves behind a string of flipped spins. Exact solutions show that on an infinite chain, the transport responses of the models are nearly identical. However, on finite-length chains, the broadening of discrete spectral lines is much more noticeable in the case of a domain wall.

Roles and opportunities for technicians in using digital imaging technology to perform necropsies
Creators: name: Gaudet, Ashley
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 2015

description: With the ever-changing demands of food animal practices, the roles oftechnicians within them are evolving as well. In population medicine, timely and accurate postmortem diagnoses can result in earlier detection of disease outbreaks and opportunities to make treatment and management changes. Digital postmortem examinations have been used with great success in the feedlot industry, and advances in digital imaging technology now allow for the capture and transfer of images of advanced diagnostic quality without being cost-prohibitive. Technicians have the opportunity, through assisting in the collection of necropsy data using digital imaging technology, to greatly influence the number of animals being necropsied annually by providing cost-effective options for producers. The details provided herein are meant to assist technicians in using digital imaging technology to perform necropsies in a consistent and standardized fashion while outlining opportunities for other uses of digital imaging technology.

description: Determining the physical mechanisms that extract energy from turbulent fluctuations in weakly collisional magnetized plasmas is necessary for a more complete characterization of the behavior of a variety of space and astrophysical plasmas. Such a determination is complicated by the complex nature of the turbulence as well as observational constraints, chiefly that in situ measurements of such plasmas are typically only available at a single point in space. Recent work has shown that correlations between electric fields and particle velocity distributions constructed from single-point measurements produce a velocity-dependent signature of the collisionless damping mechanism. We extend this work by constructing field-particle correlations using data sets drawn from single points in strongly driven, turbulent, electromagnetic gyrokinetic simulations to demonstrate that this technique can identify the collisionless mechanisms operating in such systems. The correlation's velocity-space structure agrees with expectations of resonant mechanisms transferring energy collisionlessly in turbulent systems. This work motivates the eventual application of field-particle correlations to spacecraft measurements in the solar wind, with the ultimate goal to determine the physical mechanisms that dissipate magnetized plasma turbulence.

description: Routinely recording the body condition score (BCS) of dairy cattle is a valuable tool for managers and consultants on the dairy. Using solid guidelines based on reputable resources, a consistent analysis may be made for the whole herd and create a data set which will show trends over time. By managing the data using a computer spreadsheet program, BCS may be sorted and examined by a variety of criteria, including days in milk (DIM), parity, stage of lactation, pen number, or any other relevant parameters. Monitoring the BCSs on a regular basis will provide an invaluable set of data that can be used to observe not only the nutritional management of the herd, but the reproductive management, welfare, and environmental conditions of the dairy as well.

Evaluating total mixed rations
Creators: name: Pitman, Lauren B.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 2015

description: Creating a well-balanced and properly mixed feed ration is essential to dairy cow productivity and health. The dairy's feeding manager should have two objectives: 1) to have the nutrient composition of the ration consumed by the cows the same as the one for the nutritionist’s ration on paper, and 2) for the nutrient profile of the freshly delivered feed to be the same as the one in the leftovers the next morning. Along with the ingredients loaded in the mixture, the particle size distribution plays an important role in determining the ration the cow actually consumes and digests. It is important to evaluate the total mixed ration (TMR) to determine whether there is an opportunity to improve at any step in the process of making the feed, including the forage harvest, ingredient loading and mixing, and feed delivery. Useful, on-farm tools like the Penn State Particle Separator (PSPS) have proven to be key in monitoring TMRs on a variety of levels. Recording PSPS results along with lab nutrient analysis results over time will create a history of what is being fed out and consumed by the cattle and allow for monitoring of trends and identifying potential issues.

description: O Transtorno do Déficit de Atenção com Hiperatividade (TDAH) é uma condição neurobiológica que emerge predominantemente na fase da infância e comumente mantém sua presença ao longo de toda a trajetória de vida do indivíduo. Esta condição é referida em inglês como Attention Deficit Disorder (ADD), Attention Deficit Hyperactivity Disorder (ADHD), ou simplesmente AD/HD. O TDAH é caracterizado por sintomas contínuos como desatenção, hiperatividade e impulsividade. Pessoas com TDAH frequentemente têm dificuldade em se concentrar em tarefas, são impulsivas em suas ações e apresentam agitação constante. Além disso, podem ter dificuldade em seguir instruções e frequentemente perdem objetos pessoais. Em alguns casos mais raros, pessoas com TDAH podem apresentar algum nível de agressividade. Estes sintomas podem variar em intensidade e impacto de pessoa para pessoa. Pessoas que frequentemente manifestam esse transtorno podem experimentar desafios significativos no contexto escolar. Essas manifestações do TDAH frequentemente resultam em desafios acadêmicos consideráveis, incluindo um comportamento disruptivo que pode prejudicar o ambiente de aprendizado, uma notável inquietação que interfere com a capacidade de prestar atenção durante as aulas e, em muitos casos, uma tendência a desrespeitar as regras e limites estabelecidos por professores e autoridades escolares. De acordo com a Lei Brasileira de Inclusão da Pessoa com Deficiência nº 13.146/2015, a tecnologia assistiva é definida como um conjunto abrangente de produtos, equipamentos, dispositivos, recursos, metodologias, estratégias, práticas e serviços com o propósito de promover a funcionalidade relacionada às atividades e à participação de pessoas com deficiência ou mobilidade reduzida. Inicialmente, conduziremos um minucioso trabalho de revisão sistemática da literatura (RSL), empregando diversas bases de dados, incluindo Scopus, Engineering Village, Scielo, Web of Science e IEEE - Institute of Electrical and Electronics.

description: We report the experimental observation of spin-orbit torque induced switching of perpendicularly magnetized Pt/Co elements in a time resolved stroboscopic experiment based on high resolution Kerr microscopy. Magnetization dynamics is induced by injecting sub-nanosecond current pulses into the bilayer while simultaneously applying static in-plane magnetic bias fields. Highly reproducible homogeneous switching on time scales of several tens of nanoseconds is observed. Our findings can be corroborated using micromagnetic modelling only when including a field-like torque term as well as the Dzyaloshinskii-Moriya interaction mediated by finite temperature.

THE COMPARATIVE ANALYSIS OF METAPHORICAL EXPRESSIONS IN E. HEMINGWAY'S A FAREWELL TO ARMS
Creators: name: Nezomov, Mirzokhid
Publisher: name: Zenodo
Year: 2025

description: This paper presents the important role of metaphorical expressions as a key stylistic device in Ernest Hemingway’s novel A Farewell to Arms and examines how metaphors are used in the Uzbek translation. By using stylistic and comparative analysis, the study investigates the key metaphorical expressions that contribute to the novel’s emotional tone, thematic depth, and narrative structure. The results show that while most metaphors are preserved during translation, some experience a modification, reflecting cultural adaptation and linguistic difficulties. The results highlight the importance of metaphor in Hemingway’s style and the difficulties translators face in maintaining stylistic authenticity across languages.

Two-stage Stochastic Programming under Multivariate Risk Constraints with an Application to Humanitarian Relief Network Design

description: In this study, we consider two classes of multicriteria two-stage stochastic programs in finite probability spaces with multivariate risk constraints. The first-stage problem features a multivariate stochastic benchmarking constraint based on a vector-valued random variable representing multiple and possibly conflicting stochastic performance measures associated with the second-stage decisions. In particular, the aim is to ensure that the associated random outcome vector of interest is preferable to a specified benchmark with respect to the multivariate polyhedral conditional value-at-risk (CVaR) or a multivariate stochastic order relation. In this case, the classical decomposition methods cannot be used directly due to the complicating multivariate stochastic benchmarking constraints. We propose an exact unified decomposition framework for solving these two classes of optimization problems and show its finite convergence. We apply the proposed approach to a stochastic network design problem in a pre-disaster humanitarian logistics context and conduct a computational study concerning the threat of hurricanes in the Southeastern part of the United States. Our numerical results on these large-scale problems show that our proposed algorithm is computationally scalable.

description: A brief Chandra observation of the ultraluminous quasar, SDSS J010013.02+280225.8 at redshift 6.326, showed it to be a relatively bright, soft X-ray source with a count rate of about 1 ct/ks. In this paper we present results for the quasar from a 65ks XMM-Newton observation, which well constrains its spectral shape. The quasar is clearly detected with a total of $\sim$ 460 net counts in the 0.2-10 keV band. The spectrum is characterised by a simple power-law model with photon index of $Γ= 2.30^{+0.10}_{-0.10}$, and the intrinsic 2-10 keV luminosity is $3.14\times10^{45}$ erg $\text{s}^{-1}$. The 1 $σ$ upper limit to any intrinsic absorption column density is $N_{H} = 6.07\times 10^{22} {\text{cm}}^{-2}$. No significant iron emission lines were detected. We derive the X-ray-to-optical flux ratio $α_{\text{ox}}$ of $-1.74\pm$0.01, consistent with the values found in other quasars of comparable ultraviolet luminosity. We did not detect significant flux variations either in the XMM-Newton exposure or between XMM-Newton and XMM-Newton observations, which are separated by $\sim$ 8 months. The X-ray observation enables the bolometric luminosity to be calculated after modelling the spectral energy distribution: the accretion rate is found to be sub-Eddington.

A comparison with the LHCb data on rapidity distributions and photon - hadron cross sections is presented.

description: We study two-loop quantum corrections to the low-energy effective actions in N=(2,2) and N=(4,4) SQED in the Coulomb branch. In the latter model, the low-energy effective action is described by a generalized Kahler potential which depends on both chiral and twisted chiral superfields. We demonstrate that this generalized Kahler potential is one-loop exact and corresponds to the N=(4,4) sigma-model with torsion presented by Rocek, Schoutens and Sevrin. In the N=(2,2) SQED, the effective Kahler potential is not protected against higher-loop quantum corrections. The two-loop quantum corrections to this potential and the corresponding sigma-model metric are explicitly found.

title: Improved Security Evaluation of SPN Block Ciphers and its Applications in the Single-key Attack on SKINNY
Creators: name: Zhang, Wenying
name: Cao, Meichun
name: Guo, Jian
name: Pasalic, Enes
Publisher: name: Ruhr-Universität Bochum

description: In this paper, a new method for evaluating the integral property, truncated and impossible differentials for substitution-permutation network (SPN) block ciphers is proposed. The main assumption is an explicit description/expression of the internal state words in terms of the plaintext (ciphertext) words. By counting the number of times these words occur in the internal state expression, we can evaluate the resistance of a given block cipher to integral and impossible/truncated differential attacks more accurately than previous methods. More precisely, we explore the cryptographic consequences of uneven frequency of occurrences of plaintext (ciphertext) words appearing in the algebraic expression of the internal state words. This approach gives a new family of distinguishers employing different concepts such as the integral property, impossible/truncated differentials and the so-called zero-sum property. We then provide algorithms to determine the maximum number of rounds of such new types of distinguishers for SPN block ciphers. The potential and efficiency of this relatively simple method is confirmed through applications. For instance, in the case of SKINNY block cipher, several 10-round integral distinguishers, all of the 11-round impossible differentials, and a 7-round truncated differential could be determined. For the last case, using a single pair of plaintexts differing in three words so that (a = b = c) ≠ (a’ = b’ = c’), we are able to distinguish 7-round SKINNY from random permutations. More importantly, exploiting our distinguishers, we give the first practical attack on 11-round SKINNY-128-128 in the single-key setting (a theoretical attack reaches 16 rounds). Finally, using the same ideas, we provide a concise explanation on the existing distinguishers for round-reduced AES.

Publisher: name: Ruhr-Universität Bochum
Year: 2020

description: Subterranean 2.0 designed by Daemen, Massolino and Rotella is a Round 2 candidate of the NIST Lightweight Cryptography Standardization process. In the official document of Subterranean 2.0, the designers have analyzed the state collisions in unkeyed absorbing by reducing the number of rounds to absorb the message from 2 to 1. However, little cryptanalysis of the authenticated encryption scheme Subterranean-SAE is made. For Subterranean-SAE, the designers introduce 8 blank rounds to separate the controllable input and output, and expect that 8 blank rounds can achieve a sufficient diffusion. Therefore, it is meaningful to investigate the security by reducing the number of blank rounds. Moreover, the designers make no security claim but expect a non-trivial effort to achieve full-state recovery in a nonce-misuse scenario. In this paper, we present the first practical full-state recovery attack in a nonce-misuse scenario with data complexity of 213 32-bit blocks. In addition, in a nonce-respecting scenario and if the number of blank rounds is reduced to 4, we can mount a key-recovery attack with 2122 calls to the internal permutation of Subterranean-SAE and 269.5 32-bit blocks. A distinguishing attack with 233 calls to the internal permutation of Subterranean-SAE and 233 32-bit blocks is achieved as well. Our cryptanalysis does not threaten the security claim for Subterranean-SAE and we hope it can enhance the understanding of Subterranean-SAE.

title: Security of the Suffix Keyed Sponge
Creators: name: Dobraunig, Christoph
name: Mennink, Bart
Publisher: name: Ruhr-Universität Bochum
Year: 2020

description: We formalize and analyze the general suffix keyed sponge construction, a pseudorandom function built on top of a cryptographic permutation. The construction hashes its data using the (keyless) sponge construction, transforms part of the state using the secret key, and generates the tag from the output of a final permutation call. In its simplest form, if the key and tag size are at most the rate of the sponge, one can see the suffix keyed sponge as a simple sponge function evaluation whose input is the plaintext appended with the key. The suffix keyed sponge is, however, much more general: the key and tag size may exceed the rate without any need to make extra permutation calls. We prove that the suffix keyed sponge construction achieves birthday-bound PRF security in the capacity, even if key and tag size exceed the rate. Furthermore, we prove that if the absorption of the key into the state happens in a leakage resilient manner, the suffix keyed sponge itself is leakage resilient as well. Our findings show that the suffix keyed sponge compares favorably with the hash-then-MAC construction. For instance, to reach a security level of k bits, the side-channel protected component in the suffix keyed sponge just needs to process k bits of input besides the key, whereas schemes following the hash-then-MAC construction need a side-channel protected MAC function that processes 2k bits of input besides the key. Moreover, even if we just consider black-box attacks, the MAC function in a hash-then-MAC scheme needs to be cryptographically strong whereas in the suffix keyed sponge the key may be absorbed by a simple XOR. The security proofs are performed using the H-coefficient technique, and make effective use of the multicollision limit function results of Daemen et al. (ASIACRYPT 2017), both for arguing that state manipulation larger than the rate is tolerated after key processing and for upper bounding the amount of leakage an attacker may gain about the secret key.

description: In this article, we investigate the determination of the spatial component in the time-dependent second order coefficient of a hyperbolic equation from both theoretical and numerical aspects. By the Carleman estimates for general hyperbolic operators and an auxiliary Carleman estimate, we establish local Hölder stability with both partial boundary and interior measurements under certain geometrical conditions. For numerical reconstruction, we minimize a Tikhonov functional which penalizes the gradient of the unknown function. Based on the resulting variational equation, we design an iteration method which is updated by solving a Poisson equation at each step. One-dimensional prototype examples illustrate the numerical performance of the proposed iteration.

description: We present results from a non-cosmological, three-dimensional hydrodynamical simulation of the gas in the dwarf spheroidal galaxy Ursa Minor. Assuming an initial baryonic-to-dark-matter ratio derived from the cosmic microwave background radiation, we evolved the galactic gas distribution over 3 Gyr, taking into account the effects of the types Ia and II supernovae. For the first time, we used in our simulation the instantaneous supernovae rates derived from a chemical evolution model applied to spectroscopic observational data of Ursa Minor. We show that the amount of gas that is lost in this process is variable with time and radius, being the highest rates observed during the initial 600 Myr in our simulation. Our results indicate that types Ia and II supernovae must be essential drivers of the gas loss in Ursa Minor galaxy (and probably in other similar dwarf galaxies), but it is ultimately the combination of galactic winds powered by these supernovae and environmental effects (e.g., ram-pressure stripping) that results in the complete removal of the gas content.

title: Vectorized linear approximations for attacks on SNOW 3G

description: SNOW 3G is a stream cipher designed in 2006 by ETSI/SAGE, serving in 3GPP as one of the standard algorithms for data confidentiality and integrity protection. It is also included in the 4G LTE standard. In this paper we derive vectorized linear approximations of the finite state machine in SNOW3G. In particular,we show one 24-bit approximation with a bias around 2−37 and one byte-oriented approximation with a bias around 2−40. We then use the approximations to launch attacks on SNOW 3G. The first approximation is used in a distinguishing attack resulting in an expected complexity of 2172 and the second one can be used in a standard fast correlation attack resulting in key recovery in an expected complexity of 2177. If the key length in SNOW 3G would be increased to 256 bits, the results show that there are then academic attacks on such a version faster than the exhaustive key search.

description: The development of advanced spintronics devices hinges on the efficient generation and utilization of pure spin current. In materials with large spin-orbit coupling, the spin Hall effect may convert charge current to pure spin current and a large conversion efficiency, which is quantified by spin Hall angle (SHA), is desirable for the realization of miniaturized and energy efficient spintronic devices. Here, we report a giant SHA in beta-tungsten (\b{eta}-W) thin films in Sub/W(t)/Co20Fe60B20(3 nm)/SiO2(2 nm) heterostructures with variable W thickness. We employed an all-optical time-resolved magneto-optical Kerr effect microscope for an unambiguous determination of SHA using the principle of modulation of Gilbert damping of the adjacent ferromagnetic layer by the spin-orbit torque from the W layer. A non-monotonic variation of SHA with W layer thickness (t) is observed with a maximum of about 0.4 at about t = 3 nm, followed by a sudden reduction to a very low value at t = 6 nm. This variation of SHA with W-thickness correlates well with the thickness dependent structural phase transition and resistivity variation of W above the spin diffusion length of W, while below this length the interfacial electronic effect at W/CoFeB influences the estimation of SHA.

Igualdade

description: RESUMO

O Transtorno do Espectro Autista (TEA) é uma condição complexa que impacta diversos aspectos da vida, apresentando desafios desde o diagnóstico até a inclusão na sociedade, tendo isso em vista, essa pesquisa buscou analisar a proteção jurídica no Brasil em relação ao TEA, com foco na aplicação do princípio da igualdade material, a jornada das pessoas com TEA envolve obstáculos significativos relacionados à comunicação, interação social e habilidades sensoriais, sendo que a proteção jurídica se destaca como ferramenta essencial para promover a igualdade material, reconhecendo as particularidades do TEA, são identificados diversos avanços legais, como a Lei da Carteira de Identificação do TEA, entretanto, embora tenha avançado com leis como a Lei Brasileira de Inclusão da Pessoa com Deficiência, ainda enfrenta desafios na aplicação efetiva, tendo em vista que a aplicação efetiva das leis demanda esforços contínuos das instituições governamentais e da sociedade civil, sendo que além da conformidade legal, a conscientização e aceitação social são cruciais, portanto a criação de ambientes inclusivos, conforme evidenciado por diversos autores, é essencial para a promoção da igualdade material, assim como é observado a necessidade de constante revisão da legislação para atender às demandas dinâmicas dessa população.

description: Research and Development in recent years has led to first commercially available, magnetically levitated planar motor systems. Considering the advantages of such systems, they perfectly fit as a substitute for multi-axis fine positioning stages in high-volume productions. To address the need for solutions for high-volume packaging of optical devices, we present a novel concept for a micro-assembly station using a planar motor. To qualify a novel, vacuum-operatable planar motor system for our design, we conducted experiments regarding positioning repeatability, positioning noise, and dynamics on a pre-series system.
title: Weak Keys in the Rekeying Paradigm: Application to COMET and mixFeed
Creators: name: Khairallah, Mustafa
Publisher: name: Ruhr-Universität Bochum
Year: 2020

description: In this paper, we study a group of AEAD schemes that use rekeying as a technique to increase efficiency by reducing the state size of the algorithm. We provide a unified model to study the behavior of the keys used in these schemes, called Rekey-and-Chain (RaC). This model helps understand the design of several AEAD schemes. We show generic attacks on these schemes based on the existence of certain types of weak keys. We also show that the borderline between multi-key and single-key analyses of these schemes is not solid and the analysis can be performed independent of the master key, leading sometimes to practical attacks in the multi-key setting. More importantly, the multi-key analysis can be applied in the single key setting, since each message is encrypted with a different key. Consequently, we show gaps in the security analysis of COMET and mixFeed in the single key setting, which led the designers to provide overly optimistic security claims. In the case of COMET, full key recovery can be performed with 264 online queries and 264 offline queries in the single-key setting, or 246 online queries per user and 264 offline queries in the multi-key setting with ∼ 0.5 million users. In the case of mixFeed, we enhance the forgery adversarial advantage in the single-key setting with a factor of 267 compared to what the designers claim. More importantly, our result is just a lower bound of this advantage, since we show that the gap in the analysis of mixFeed depends on properties of the AES Key Schedule that are not well understood and require more cryptanalytic efforts to find a more tight advantage. After reporting these findings, the designers updated their security analyses and accommodated the proposed attacks.

description: Presented hereby is the 5th in a series of PhD theses prepared in Tartu University, addressing genetics of population history of the South Asian peoples. Inhabited considerably before the Last Glacial Maximum, the region harbors by now about 1.8 billion humans – almost a quarter of the global population. Therefore, understanding of present-day variation of the latter, in particular outside sub-Saharan Africa, is not possible without deeper knowledge about genetics of South Asian populations. This thesis is based on four published papers. The first one is focused on selected populations inhabiting northeastern Indus Valley, bearing, in particular, in mind ancient Indus Valley civilization and following it Vedic period. The second and the third paper address historically somewhat better known migrations, bringing to India religiously distinct Parsi and Jewish peoples. The fourth paper analyses the genetic variation of a populous Tharu tribe, living predominantly in Nepal, but also in northern provinces of India. Perhaps the most interesting finding of the first paper is that the presumably identified already in Vedic texts, Ror population exhibits significant genetic affinity with northern Steppe and West European peoples, testifying about prehistoric north to south migration(s). The arrival of Parsis to South Asia in 7th century was a consequence of the Islamization of Iran. Comparing Parsi genomes in their historic contexts, we observed their extensive admixture with South Asians, in particular, asymmetrically in paternal and maternal lineages. Nearly the same can be said about different Indian communities that preserved Judaist traditions: their genomes show affinities to peoples living in the Near and Middle East. As far as the genetically highly diverse Tharu tribe is concerned, a clearly distinct East Asian contribution can be seen, admixed with South Asian genetic heritage. It seems justified to identify the Tharu as cultural, rather than demic phenomenon.
