description: We investigate the nonlinear regime of charge and energy transport through Coulomb-blockaded quantum dots. We discuss crossed effects that arise when electrons move in response to thermal gradients (Seebeck effect) or energy flows in reaction to voltage differences (Peltier effect). We find that the differential thermoelectric conductance shows a characteristic Coulomb butterfly structure due to charging effects. Importantly, we show that experimentally observed thermovoltage zeros are caused by the activation of Coulomb resonances at large thermal shifts. Furthermore, the power dissipation asymmetry between the two attached electrodes can be manipulated with the applied voltage, which has implications for the efficient design of nanoscale coolers.

description: A rotating organic cation and a dynamically disordered soft inorganic cage are the hallmark features of hybrid organic-inorganic lead-halide perovskites. Understanding the interplay between these two subsystems is a challenging problem but it is this coupling that is widely conjectured to be responsible for the unique behavior of photo-carriers in these materials. In this work, we use the fact that the polarizability of the organic cation strongly depends on the ambient electrostatic environment to put the molecule forward as a sensitive probe of local crystal fields inside the lattice cell. We measure the average polarizability of the C/N--H bond stretching mode by means of infrared spectroscopy, which allows us to deduce the character of the motion of the cation molecule, find the magnitude of the local crystal field and place an estimate on the strength of the hydrogen bond between the hydrogen and halide atoms. Our results pave the way for understanding electric fields in lead-halide perovskites using infrared bond spectroscopy.

description: Autonomous vehicles (AVs) have become increasingly prevalent in modern society, with multiple companies pursuing avenues to advance technology. Despite the promises of safer driving, mitigating accidents and reducing stress, mixed opinions exist on the reliability and trustworthiness of the technology. While many factors form opinions regarding AVs, the component of personal values in AV discourse has not been well-documented. This research focuses on understanding which personal values are most prominent in AV discourse and how individuals prioritize these personal values. We studied two AV-focused data sources to gain perspective: 24 TED Talk transcripts and 20,000 Reddit user posts. Next, we scored the prevalence of personal values using the Personal Values Dictionary (PVD). Our results found that self-direction, achievement, power, stimulation, and conformity had an overall positive inclination in AV discourse. However, we also found value conflicts between both data sets, indicating a potential dissonance between professional opinions and those of typical consumers. Our findings provide insight into values literature and issues consumers bring up when discussing or adopting AVs. Our research on value conflicts can also link to consumers' potential adoption of AVs. Thus, we provide potentially useful perspectives for companies to address these concerns directly in their AV production, advertising, and design philosophies.

description: Tungsten diselenide (WSe2), a semiconducting transition metal dichalcogenide (TMDC), shows great potential as active material in optoelectronic devices due to its ambipolarity and direct bandgap in its single-layer form. Recently, different groups have exploited the ambipolarity of WSe2 to realize electrically tunable PN junctions, demonstrating its potential for digital electronics and solar cell applications. In this Letter, we focus on the different photocurrent generation mechanisms in a double-gated WSe2 device by measuring the photocurrent (and photovoltage) as the local gate voltages are varied independently in combination with above- and below-bandgap illumination. This enables us to distinguish between two main photocurrent generation mechanisms: the photovoltaic and photothermoelectric effect. We find that the dominant mechanism depends on the defined gate configuration. In the PN and NP configurations, photocurrent is mainly generated by the photovoltaic effect and the device displays a maximum responsivity of 0.70 mA/W at 532 nm illumination and rise and fall times close to 10 ms. Photocurrent generated by the photothermoelectric effect emerges in the PP configuration and is a factor of two larger than the current generated by the photovoltaic effect (in PN and NP configurations). This demonstrates that the photothermoelectric effect can play a significant role in devices based on WSe2 where a region of strong optical absorption, caused by e.g. an asymmetry in flake thickness or optical absorption of the electrodes, generates a sizeable thermal gradient upon illumination.

Computationally Relaxed Locally Decodable Codes, Revisited

description: We revisit computationally relaxed locally decodable codes (crLDCs) (Blocki et al., Trans. Inf. Theory '21) and give two new constructions. Our first construction is a Hamming crLDC that is conceptually simpler than prior constructions, leveraging digital signature schemes and an appropriately chosen Hamming code. Our second construction is an extension of our Hamming crLDC to handle insertion-deletion (InsDel) errors, yielding an InsDel crLDC. This extension crucially relies on the noisy binary search techniques of Block et al. (FSTTCS '20) to handle InsDel errors. Both crLDC constructions have binary codeword alphabets, are resilient to a constant fraction of Hamming and InsDel errors, respectively, and under suitable parameter choices have poly-logarithmic locality and encoding length linear in the message length and polynomial in the security parameter. These parameters compare favorably to prior constructions in the poly-logarithmic locality regime.

description: The dynamics of two interacting quantum particles on a weakly disordered chain is investigated. Spatial quantum interference between them is characterized through the statistics of two-particle transition amplitudes, related to Hanbury Brown-Twiss correlations in optics. The fluctuation profile of the signal can discern whether the interacting parties are behaving like identical bosons, fermions, or distinguishable particles. An analog fully developed speckle regime displaying Rayleigh statistics is achieved for interacting bosons. Deviations toward long-tailed distributions echo quantum correlations akin to non-interacting identical particles. In the limit of strong interaction, two-particle bound states obey generalized Rician distributions.

description: The heat transport in rotating Rayleigh-Bénard convection (RBC) can be significantly enhanced for moderate rotation, i.e., for an intermediate range of Rossby numbers $Ro$, compared to the non-rotating case. At Rayleigh numbers $Ra\lesssim5\cdot10^8$, the largest heat transport enhancement (HTE) is achieved when the thicknesses of kinetic and thermal boundary layer are equal. However, experimental and numerical observations show that, at larger $Ra$ ($\gtrsim5\cdot10^8$), the maximal HTE starts to deviate from the expected optimal boundary layer ratio and its amplitude decreases drastically. We present data from direct numerical simulations of rotating RBC in a periodic domain in the range of $10^7\leq Ra\leq10^{10}$ and $0\leq Ro^{-1}\leq40$ for Prandtl number $Pr=4.38$ and $6.4$ to identify the reason for the transition to this large $Ra$ regime of HTE. Our analysis reveals that the transition occurs once the bulk flow at the optimal boundary layer ratio changes to geostrophic turbulence for large $Ra$. In that flow state, the vertically coherent vortices, which support HTE by Ekman pumping at smaller $Ra$, dissolve into vertically decorrelated structures in the bulk, such that the enhancing effect of Ekman pumping and the influence of the boundary layer ratio become small. Additionally, more heat leaks out of the Ekman vortices as the fraction of thermal dissipation in the bulk increases. We find that the rotation induced shearing at the plates helps to increase the thermal dissipation in the bulk, and thus acts as a limiting factor for HTE at large $Ra$: beyond a certain ratio of wall shear stress to vortex strength, the heat transport decreases irrespectively of the boundary layer ratio. This $Pr$ dependent threshold, which roughly corresponds to a bulk accounting for $\approx1/3$ of the total thermal dissipation, sets the maximal HTE and the optimal rotation rate at large $Ra$.

description: These lecture notes accompany a refresher course in applied mathematics with a focus on numerical concepts (Part I), numerical linear algebra (Part II), numerical analysis, Fourier series and Fourier transforms (Part III), and differential equations (Part IV). Several numerical projects for group work are provided in Part V. In these projects, the tasks are fivefold: mathematical modeling, algorithmic design, implementation, presenting scientific findings, and learning how to interpret those results in order to draw scientific conclusions. Therefore, we provide measures (Parts I-IV) how to build confidence into numerical findings such as intuition, error analysis, convergence analysis, and comparison to manufactured solutions. Both authors have been jointly teaching over several years this class and bring in a unique mixture of their respective teaching and research fields.

description: We present the first results of our search for new, extended Planetary Nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS). The newly uncovered PNe will help to improve the census of this important population of Galactic objects that serve as key windows into the late stage evolution of low to intermediate mass stars. They will also facilitate study of the faint end of the ensemble Galactic PN luminosity function. The sensitivity and coverage of IPHAS allows PNe to be found in regions of greater extinction in the Galactic Plane and/or those PNe in a more advanced evolutionary state and at larger distances compared to the general Galactic PN population. Using a set of newly revised optical diagnostic diagrams in combination with access to a powerful, new, multi-wavelength imaging database, we have identified 159 true, likely and possible PNe for this first catalogue release. The ability of IPHAS to unveil PNe at low Galactic latitudes and towards the Galactic Anticenter, compared to previous surveys, makes this survey an ideal tool to contribute to the improvement of our knowledge of the whole Galactic PN population

description: В последние годы явно возрос интерес к интеллектуальному наследию эпохи Просвещения. Кажется, что это до некоторой степени связано с упадком постмодернистского дискурса. Джонатан Израэль один из главных поборников «возрождения» интереса к исследованиям мысли века Просвещения. Он опубликовал несколько объемных работ по истории идей XVIII столетия, которые весьма критичны относительно постмодернистских интерпретаций этой истории. Однако, несмотря на многие позитивные аспекты творчества Израэля, возникают и некоторые проблемы. В статье рассматриваются три основных вопроса. Во-первых, проблематично резкое различие, которое делает Израэль между «мейнстримом» и «радикальным» Просвещением. Проблематично потому, что это затрудняет оценку таких мыслителей, как Руссо или Кант. Во-вторых, Израэль сжимает все радикальное Просвещение до спинозизма, что явно не соответствует историческим фактам. И в-третьих, он слишком настаивает на том, что Просвещение следует рассматривать как движение идей и теорий, пренебрегая социально-экономическими корнями интеллектуальных изменений в XVIII в.

description: The metal based phosphate and sulfate mixture, Cu3(PO4)2⋅ 1.65 NaH2PO4 ⋅ 1.35 NaHSO4 has been synthesized and characterized with different measurement techniques. Six different composites such as A1, A2, A3, A4, A5 and A6 have been synthesized by charging different proportions of a mixture with a fixed quantity of wall care putty (Birla make). Similarly, four different composites such as B1, B2, B3 and B4 have been synthesized by charging different proportion of a mixture with a fixed quantity of CaCO3 and polyvinyl acetate (PVAc) glue. The C1 mixture has also been synthesized using CaCO3 and polyvinyl acetate (PVAc) glue without the addition of the mixture. The thermal behavior was evaluated in the temperature range 303 K to 573 K and vice versa in two thermal cycles as well as from 173 K from 298 K for one thermal cycle. The thermal behavior of the mixture was studied at a rate of 10 K min−1 while composites were studied at 5 K min−1. The net specific heat capacities (Cp) of composites are found to be, A2 (-0.11 Jg−1K−1), A3 (-0.13 Jg−1K−1), A6 (-0.12 Jg−1K−1), B1 (-0.13 Jg−1K−1), B2 (-0.10 Jg−1K−1), B3 (-0.11 Jg−1K−1) and B4 (-0.17 Jg−1K−1). These composites can be utilized as heat retardant materials.

description: In the independent electron approximation, the average (energy/charge/entropy) current flowing through a finite sample S connected to two electronic reservoirs can be computed by scattering theoretic arguments which lead to the famous Landauer-Büttiker formula. Another well known formula has been proposed by Thouless on the basis of a scaling argument. The Thouless formula relates the conductance of the sample to the width of the spectral bands of the infinite crystal obtained by periodic juxtaposition of S. In this spirit, we define Landauer-Büttiker crystalline currents by extending the Landauer-Büttiker formula to a setup where the sample S is replaced by a periodic structure whose unit cell is S. We argue that these crystalline currents are closely related to the Thouless currents. For example, the crystalline heat current is bounded above by the Thouless heat current, and this bound saturates iff the coupling between the reservoirs and the sample is reflectionless. Our analysis leads to a rigorous derivation of the Thouless formula from the first principles of quantum statistical mechanics.
Massless KG-oscillators in Som-Raychaudhuri cosmic string spacetime in a fine tuned rainbow gravity

Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A fine tuned rainbow gravity describes both relativistic quantum particles and anti-particles alike. That is, the ratio $y=E/E_{P}$ in the rainbow functions $g_{_{0}}\left( y\right) $ and $% g_{_{1}}\left( y\right) $ should be fine tuned into $0\leq y=E/E_{P}\leq 1\Rightarrow y=\left\vert E\right\vert /E_{P}$, otherwise rainbow gravity will only secure Planck's energy scale $E_p$ invariance for relativistic particles and the anti-particles are left unfortunate (in the sense that their energies will be indefinitely unbounded). Using this fine tuning we discuss the rainbow gravity effect on Klein-Gordon (KG) oscillators in Som-Raychaudhuri cosmic string rainbow gravity spacetime background. We use the rainbow functions: (i) $g_{_{0}}\left( y\right) =1$, $% g_{_{1}}\left( y\right) =\sqrt{1-εy^{n}}, n=0,1$, loop quantum gravity motivated pairs, (ii) $% g_{_{0}}\left( y\right) =g_{_{1}}\left( y\right) =\left( 1-εy\right) ^{-1}$, a horizon problem motivated pair, and (iii) $g_{_{0}}\left( y\right) =\left( e^{εy}-1\right) /εy$, $g_{_{1}}\left( y\right) =1$, a gamma-ray bursts motivated pair. We show that the energies obtained using the first two rainbow functions in (i) completely comply with the rainbow gravity model (on the invariance of the Planck's energy scale $E_{p}$). The rainbow function pair in (ii) has no effect on massless KG-oscillators. Whereas, the one in (iii) does not show any eminent tendency towards the invariance of the Planck's energy scale. Yet, we suggest a new rainbow function pair $(g_0(y)=(1-εy)^{-1}, g_1 (y)=1)$, and show that it secures invariance of the Planck's energy scale $E_p$. Moreover, similar performance is observed when this new pair is used for KG-oscillators and KG-Coulombic particles in cosmic string rainbow gravity spacetime and magnetic fields.

description: To bridge the gap between the sequences and 3-dimensional (3D) structures of RNAs, some computational models have been proposed for predicting RNA 3D structures. However, the existed models seldom consider the conditions departing from the room/body temperature and high salt (1M NaCl), and thus generally hardly predict the thermodynamics and salt effect. In this study, we propose a coarse-grained model with implicit salt for RNAs to predict 3D structures, stability and salt effect. Combined with Monte Carlo simulated annealing algorithm and a coarse-grained force field, the model folds 46 tested RNAs (less than or equal to 45 nt) including pseudoknots into their native-like structures from their sequences, with an overall mean RMSD of 3.5 Å and an overall minimum RMSD of 1.9 Å from the experimental structures. For 30 RNA hairpins, the present model also gives the reliable predictions for the stability and salt effect with the mean deviation ~ 1.0 degrees Celsius of melting temperatures, as compared with the extensive experimental data. In addition, the model could provide the ensemble of possible 3D structures for a short RNA at a given temperature/salt condition.

Interannual observations and quantification of summertime H2O ice deposition on the Martian CO2 ice south polar cap

description: The spectral signature of water ice was observed on Martian south polar cap in 2004 by the Observatoire pour l'Mineralogie, l'Eau les Glaces et l'Activite (OMEGA) (Bibring et al., 2004). Three years later, the OMEGA instrument was used to discover water ice deposited during southern summer on the polar cap (Langevin et al., 2007). However, temporal and spatial variations of these water ice signatures have remained unexplored, and the origins of these water deposits remains an important scientific question. To investigate this question, we have used observations from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument on the Mars Reconnaissance Orbiter (MRO) spacecraft of the southern cap during austral summer over four Martian years to search for variations in the amount of water ice. We report below that for each year we have observed the cap, the magnitude of the H2O ice signature on the southern cap has risen steadily throughout summer, particularly on the west end of the cap. The spatial extent of deposition is in disagreement with the current best simulations of deposition of water ice on the south polar cap (Montmessin et al., 2007). This increase in water ice signatures is most likely caused by deposition of atmospheric H2O ice and a set of unusual conditions makes the quantification of this transport flux using CRISM close to ideal. We calculate a 'minimum apparent' amount of deposition corresponding to a thin H2O ice layer of 0.2mm (with 70 percent porosity). This amount of H2O ice deposition is 0.6-6 percent of the total Martian atmospheric water budget. We compare our 'minimal apparent' quantification with previous estimates. This deposition process may also have implications for the formation and stability of the southern CO2 ice cap, and therefore play a significant role in the climate budget of modern day Mars.

description: We study self-excited oscillations (SEO) in an on-fiber optomechanical cavity. Synchronization is observed when the optical power that is injected into the cavity is periodically modulated. A theoretical analysis based on the Fokker-Planck equation evaluates the expected phase space distribution (PSD) of the self-oscillating mechanical resonator. A tomography technique is employed for extracting PSD from the measured reflected optical power. Time-resolved state tomography measurements are performed to study phase diffusion and phase locking of the SEO. The detuning region inside which synchronization occurs is experimentally determined and the results are compared with the theoretical prediction.

description: We study the lifetime of locally stable states in the Thirring model, which describes a system of particles whose interactions are long-range. The model exhibits first-order phase transitions in the canonical ensemble and, therefore, a free energy barrier separates two free energy minima. The energy of the system diffuses as a result of thermal fluctuations and we show that its dynamics can be described by means of a Fokker-Planck equation. Considering an initial state where the energy takes the value corresponding to one of the minima of the free energy, we can define the lifetime of the initial state as the mean first-passage time for the system to reach the top of the free energy barrier between the minima. We use an analytical formula for the mean first-passage time which is based on the knowledge of the exact free energy of the model, even at a finite number of particles. This formula shows that the lifetime of locally stable states increases exponentially in the number of particles, which is a typical feature of systems with long-range interactions. We also perform Monte Carlo simulations in the canonical ensemble in order to obtain the probability distribution of the first-passage time, which turns out to be exponential in time in a long time limit. The numerically obtained mean first-passage time agrees with the theoretical prediction. Combining theory and simulations, our work provides a new insight in the study of metastability in many-body systems with long-range interactions.

description: Described herein is a process that accomplishes the iodine-promoted C-H sulfidation of electron-deficient fluorine-containing aromatic compounds with benzenethiols. This method effectively enables the unsymmetrical bis-sulfidation of pentafluorobenzene. Also, this oxidizing system could be applied to the C-H selenation of fluorine-containing aromatic compounds bearing either alkyl or aryl sulfide moieties, which could plausibly lead to the introduction of two different chalcogen atoms on tetrafluorobenzene derivatives.

description: Direct minimisation of a cost function can in principle provide a versatile and highly controllable route to computational hologram generation. However, to date iterative Fourier transform algorithms have been predominantly used. Here we show that the careful design of cost functions, combined with numerically efficient conjugate gradient minimisation, establishes a practical method for the generation of holograms for a wide range of target light distributions. This results in a guided optimisation process, with a crucial advantage illustrated by the ability to circumvent optical vortex formation during hologram calculation. We demonstrate the implementation of the conjugate gradient method for both discrete and continuous intensity distributions and discuss its applicability to optical trapping of ultracold atoms.

description: Reducing alcohol use is challenging due to the volume of alcohol shown in media and the relationship between exposure and use. It is unclear to what degree people are aware of and able to estimate alcohol exposure in the media, such as in movies. In this study, 609 Australian adults estimated the amount of alcohol exposure in up to 10 of 102 popular movies they remembered best. They reported when they last saw each movie, their alcohol use, age, and gender. Participants underestimated the amount of alcohol in movies by an average of 35.39 times. Movies classified as featuring adult content (PG-13 or R) and movies with the greatest amount of alcohol were particularly underestimated. Individual’s age, gender, alcohol use, or when the movie was last viewed had no effect on underestimation. In conclusion, due to the severe underestimation, alcohol exposure should be more seriously reviewed by governmental and medial organizations.
Tractor beams with optimal pulling force using structured waves

description: Moving objects with optical or acoustical waves is a topic both of fundamental interest and of importance for a range of practical applications. One particularly intriguing example is the tractor beam, which pulls an object toward the wave's source, in opposition to the wave's momentum. In this study, we introduce a protocol that enables the identification of wave states that produce the optimal tractor force for arbitrary objects. Our method relies solely on the solution of a simple eigenvalue problem involving the system's measurable scattering matrix. Using numerical simulations, we demonstrate the efficacy of this wavefront shaping protocol for a representative set of different targets. Moreover, we show that the diffractive nature of waves enables the possibility of a tractor beam, that works even for targets where a geometric optics approach fails to explain the pulling forces.

Выбор Н.М. Карамзина: от масонской антропологии и европейского гуманизма к провиденциализму и нравственной свободе

description: В статье рассматривается влияние гуманистических взглядов Н.М. Новикова на Н.М. Карамзина. Карамзин в течение 1784-1789 гг. находился в Обществе московских масонов, где у него появилась возможность приобщиться к пониманию ими проблемы человека. Религиозно-философское учение о человеке в России интенсивно развивалось именно в масонском дискурсе, в котором в XVIII веке преобладала мистическая составляющая. Гуманистический концепт раннего масонства, сформулированный в трактате Новикова «О достоинстве человека в отношениях к Богу и миру» (1777), близок к трактовке человека в ренессансном гуманизме. Постепенно масонский дискурс сосредоточился на концепте «ветхого человека» и понятии греха, но Карамзин остался приверженцем гуманистической позиции Новикова с ее высокой оценкой человека и характерным для этики Нового времени акцентом на понятиях добродетель и достоинство. Потрясение, вызванное драматическим развитием Французской революции, заставило его встать на позицию провиденциализма. Итогом мировоззренческого кризиса Карамзина стала консервативная утопия, в которой Карамзин обосновывал превосходство внеправовой системы власти, опирающейся на совесть правителя, интуитивно связанного с Провидением. Отход от позиции Канта выразился в том, что неоправдавший себя «нравственный закон» Карамзин заменяет понятием внутренней, нравственной свободы, что в герменевтическом смысле близко понятию моральное чувство из сентименталистской этики. Отступление от принципов Просвещения свидетельствует о включенности Карамзина в патерналистскую модель сознания. Автор приходит к заключению, что внеправовая позиция Карамзина, руководствовавшегося исключительно нравственным критерием, привела к ограничению гуманистического воздействия на процесс совершенствования личности и общества. В вопросе о методологии исследования автор приходит к выводу, что Карамзин в строго научном смысле не развивает философское учение о человеке; проблема человека у него рассматривается в границах абстрактного гуманизма, поэтому взгляды Карамзина вернее рассматривать в контексте исследования общественного сознания.

description: Within this study, 20 2-[(5,6-diaryl-1,2,4-triazin-3-yl)thio]-N-(benzo/thiazol-2-yl)acetamide derivatives (4a-4t) were synthesized and COX inhibitory activities of the compounds were investigated. Compounds 4k-4o, which have a 4-methoxyphenyl group within their structures, showed strong inhibitory activity on COX-2 enzyme, even compound 4k, namely 2-{[5,6-bis(4-methoxyphenyl)-1,2,4-triazin-3-yl]thio}-N-(thiazol-2-yl)acetamide exhibited higher selectivity on this enzyme (IC50:3.06 µM). Molecular docking studies were performed for compound 4k on COX-1 and COX-2 enzymes and the results were found to support the molecule’s COX-2 selectivity.

description: This study investigates the relationship between diet, lifestyle, gut microbiota composition, and gestational diabetes mellitus (GDM) outcomes in Malaysian Malay women. The study reveals significant differences in clinical factors, lifestyle habits, and dietary patterns between women with and without GDM. It also identifies variations in gut microbial profiles and associations with clinical factors, dietary intake, and lifestyle habits. However, these predictors did not significantly correlate with maternal/neonatal outcomes. The findings of this study highlights the importance of the gut microbiome, dietary choices, and lifestyle habits during pregnancy, but further investigation is needed to develop targeted interventions for GDM management.

description: We compute the corrections to the Schwarzschild metric necessary to reproduce the Hawking temperature derived from a Generalized Uncertainty Principle (GUP), so that the GUP deformation parameter is directly linked to the deformation of the metric. Using this modified Schwarzschild metric, we compute corrections to the standard General Relativistic predictions for the light deflection and perihelion precession, both for planets in the solar system and for binary pulsars. This analysis allows us to set bounds for the GUP deformation parameter from well-known astronomical measurements.
