description: Постановка проблемы. Для разработки низковольтных ЛБВ миллиметрового и субмиллиметрового диапазонов требуются замедляющие системы (ЗС) с широкой полосой рабочих частот и высоким сопротивлением связи, что трудно обеспечить одновременно. Такие ЗС содержат мелкоструктурные элементы и поэтому требуют дорогостоящих прецизионных технологий изготовления. По этим причинам данная проблема до сих пор сохраняет актуальность.
Цель. Представить проект планарной ЗС типа «меандр» на основе алмазного теплоотвода для ЛБВ W диапазона и провести численное и экспериментальное исследование характеристик этой ЗС.
Результаты. В работе предложена и исследована новая планарная ЗС для мощных ЛБВ W-диапазона с низким напряжением питания и ленточным пучком. В качестве носителя и теплоотвода используется подвешенная подложка из CVD-алмаза, что обеспечивает высокие электрические и тепловые характеристики прибора. При изготовлении используется доступное технологическое оборудование. Численное моделирование показало, что данная конструкция ЗС типа «меандр на подложке» позволяет обеспечить рабочую полосу частот 5 ГГц, выходную мощность27 Вт при рабочем напряжении 13 кВ.
Практическая значимость. Реализация технических решений, представленных в работе, позволит наладить разработку и серийное производство низковольтных ЛБВ W-диапазона и решить проблему импортозамещения в данной чувствительной области. Указанные ЛБВ могут быть использованы в телекоммуникационных сетях 5G в целях обеспечения программы «Цифровая экономика РФ».

description: Постановка проблемы. Благодаря высокой эмиссионной способности углеродные нанотрубки (УНТ) находят широкое применение в электронике при создании автоэмиссионных катодов. Однако при использовании в катодах УНТ в качестве эмиттера возникает проблема, связанная с разрушением нанотрубок вследствие локального разогрева в процессе эмиссии. Для решения этой проблемы требуется поиск новых композитных материалов, содержащих в своем составе УНТ. Одним из таких материалов является колонный графен, структура которого образована слоями графена и вертикально расположенными между ними нанотрубками. Для использования колонного графена в устройствах эмиссионной электроники необходимо оценить работу выхода материала и выявить закономерности управления её величиной.
Цель. Исследовать энергетическую устойчивость и работу выхода пленочных и 3D-структур колонного графена, модифицированного атомами калия.
Результаты. Построены суперячейки одно- и двухслойных тонких плёнок, а также 3D-структур колонного графена на основе однослойных УНТ(9,9) различной длины, меняющейся в диапазоне от 0.6 до 1.84 нм. Дана численная оценка энергетической устойчивости построенных суперячеек колонного графена, полости которого заполнены атомами калия с различной массовой долей. Выявлены закономерности изменения работы выхода исследуемых атомистических моделей колонного графена в зависимости от длины УНТ и массовой доли атомов калия. Определены геометрические параметры рассмотренных в работе структур колонного графена, при которых достигается наибольшее снижение работы выхода материала.
Практическая значимость. Полученные в работе результаты свидетельствуют о высоких перспективах применения модифицированного калием колонного графена в качестве материала для автоэмиссионных катодов.

description: Numerical simulation is used to characterise double potential step chronoamperometry at a microband electrode for a simple redox process A + e- goes to B, under conditions of full support such that diffusion is the only active form of mass transport. The method is shown to be highly sensitive for the measurement of the diffusion coefficient of both A and B, and is applied to the one electron reduction of decamethylferrocene (DMFc), DMFc - e- goes to DMFc+, in the room temperature ionic liquid 1-propyl-3-methylimidazolium bistrifluoromethylsulfonylimide. Theory and experiment are seen to be in excellent agreement and the following values of the diffusion coefficients were measured at 298 K: D_(DMFc) = 2.50 x 10^(-7) cm^(2) s^(-1) and D_(DMFc+) = 9.50 x 10^(-8) cm^(2) s^(-1).

description: The ionization rate of an atom in a strong optical field can be resonantly enhanced by the presence of long-living atomic levels (so-called Freeman resonances). This process is most prominent in the multiphoton ionization regime, meaning that the ionization event takes many optical cycles. Nevertheless, here, we show that these resonances can lead to rapid subcycle-scale plasma buildup at the resonant values of the intensity in the pump pulse. The fast buildup can break the cycle-to-cycle symmetry of the ionization process, resulting in the generation of persistent macroscopic plasma currents which remain after the end of the pulse. This, in turn, gives rise to a broadband radiation of unusual spectral structure, forming a comb from terahertz to visible. This radiation contains fingerprints of the attosecond electron dynamics in Rydberg states during ionization. © 2017 American Physical Society.

description: The increasing performance of optical lattice clocks has made them attractive for scientific applications in space and thus has pushed the development of their components including the interrogation lasers of the clock transitions towards being suitable for space, which amongst others requires making them more power efficient, radiation hardened, smaller, lighter as well as more mechanically stable. Here we present the development towards a space-compatible interrogation laser system for a strontium lattice clock constructed within the Space Optical Clock (SOC2) project where we have concentrated on mechanical rigidity and size. The laser reaches a fractional frequency instability of 7.9 × 10−16 at 300 ms averaging time. The laser system uses a single extended cavity diode laser that gives enough power for interrogating the atoms, frequency comparison by a frequency comb and diagnostics. It includes fibre link stabilisation to the atomic package and to the comb. The optics module containing the laser has dimensions 60 × 45 × 8 cm3; and the ultra-stable reference cavity used for frequency stabilisation with its vacuum system takes 30 × 30 × 30 cm3. The acceleration sensitivities in three orthogonal directions of the cavity are 3.6 × 10−10/g, 5.8 × 10−10/g and 3.1 × 10−10/g, where g ≈ 9.8 m/s2 is the standard gravitational acceleration.

description: Transition path sampling is a rare-event method that estimates state-to-state timecorrelation functions in many-body systems from samples of short trajectories. In this framework, it is proposed to bias the importance function using the lowest Jacobian eigenvalue moduli along the dynamical trajectory. A lowest eigenvalue modulus is related to the lowest eigenvalue of the Hessian matrix and is evaluated here using the Lanczos algorithm as in activation-relaxation techniques. This results in favoring the sampling of activated trajectories and enhancing the occurrence of the rare reactive trajectories of interest, those corresponding to transitions between locally stable states. Estimating the time-correlation functions involves unbiasing the sample of simulated trajectories which is done using the multi-state Bennett acceptance ratio (MBAR) method. To assess the performance of our procedure, we compute the time-correlation function associated with the migration of a vacancy in α-iron. The derivative of the estimated time-correlation function yields a migration rate in agreement with the one given by transition state theory. Besides, we show that the information relative to rejected trajectories can be recycled within MBAR, resulting in a substantial speed-up. Unlike original transition path-sampling, our approach does not require computing the reversible work to confine the trajectory endpoints to a reactive state.

Retrieving Landscape: A Biography of Nanhai in the Pearl River Delta, China
Creators: name: Chan, Hong Wan
Publisher: name: Zenodo
Year: 2022

description: This poster presents a general outline of my PhD research, which takes as its starting point my ancestral village located in a peri-urban area of Nanhai district in the Pearl River Delta in China. Prevalent readings of the Delta focus on the striking spatial contrasts and large scale developments that have come about since the start of the economic reforms in 1978. Instead, my research starts from the observation that it is insufficient to view this area from a developmental point of view, which risks homogenising this multi-layered landscape. Informed by my experiences on the ground, I propose a leap from the quantitative territory to the qualitative landscape, to what Tim Ingold would call “the world as it is known to those who dwell therein.”

 I center ways in which people dwell, make inhabitable the world despite marked spatial changes. This is done on the one hand on the abstract level of representing this inhabiting through text and visualisations, on the other hand on the concrete level of inscribing the lived landscape through everyday activities, thus interpreting it as “an enduring record of – and testimony to – the lives and works of the past generations who have dwelt within it, and in so doing, have left there something of themselves.” Processes today are equally valued as another chapter in the ongoing life.

 Drawing from the field of landscape biography as proposed by the Dutch archaeologist Jan Kolen and colleagues, a longue durée approach is taken in order to grasp processes and transformations of Nanhai at different rhythms and on different timescales for three aspects: the cosmological, the ancestral, and the working landscape. My PhD is structured around these three aspects of landscape, each thus forming another lens and entryway. The poster shows a glimpse of each chapter.

description: The integration of metal microstructures and soft materials is promising for the realization of novel optical and biomedical devices owing to the flexibility and biocompatibility of the latter. Nevertheless, the fabrication of three-dimensional metal structures within a soft material is still challenging. In this study, we demonstrate the fabrication of a silver diffraction grating inside a biocompatible poly(ethylene glycol) diacrylate (PEGDA) hydrogel by using a 522-nm femtosecond laser via multi-photon photoreduction of silver ions. The optical diffraction pattern obtained with the grating showed equally spaced diffraction spots, which indicated that a regular, periodic silver grating was formed. Notably, the distance between the diffraction spots changed when the water content in the hydrogel was reduced. The grating period decreased when the hydrogel shrank owing to the loss of water, but the straight shapes of the line structures were preserved, which demonstrated the optical tunability of the fabricated structure. Our results demonstrate the potential of the femtosecond laser-based photoreduction technique for the fabrication of novel tunable optical devices as well as highly precise structures. © 2017 The Author(s).

description: A new measurement of inclusive-jet cross sections in the Breit frame in neutral current deep inelastic scattering using the ZEUS detector at the HERA collider is presented. The data were taken in the years 2004 to 2007 at a centre-of-mass energy of $318\,\text{GeV}$ and correspond to an integrated luminosity of $347\,\text{pb}^{-1}$. Massless jets, reconstructed using the $k_t$-algorithm in the Breit reference frame, have been measured as a function of the squared momentum transfer, $Q^2$, and the transverse momentum of the jets in the Breit frame, $p_{\perp,\text{Breit}}$. The measured jet cross sections are compared to previous measurements and to perturbative QCD predictions. The measurement has been used in a next-to-next-to-leading-order QCD analysis to perform a simultaneous determination of parton distribution functions of the proton and the strong coupling, resulting in a value of $α_s(M_Z^2) = 0.1142 \pm 0.0017~\text{(experimental/fit)}$ ${}^{+0.0006}_{-0.0007}~\text{(model/parameterisation)}$ ${}^{+0.0006}_{-0.0004}~\text{(scale)}$, whose accuracy is improved compared to similar measurements. In addition, the running of the strong coupling is demonstrated using data obtained at different scales.

description: Lord Kelvin with his discovery of the anisotropic magnetoresistance (AMR) phenomenon in Ni and Fe was 70 years ahead of the formulation of relativistic quantum mechanics the effect stems from, and almost one and a half century ahead of spintronics whose first commercial applications relied on the AMR. Despite the long history and importance in magnetic sensing and memory technologies, the microscopic understanding of the AMR has struggled to go far beyond the basic notion of a relativistic magnetotransport phenomenon arising from combined effects on diffusing carriers of spin-orbit coupling and broken symmetry of a metallic ferromagnet. Our work demonstrates that even this seemingly generic notion of the AMR phenomenon needs revisiting as we observe the ohmic AMR effect in a nano-scale film of an antiferromagnetic (AFM) semiconductor Sr2IrO4 (SIO). Our work opens the recently proposed path for integrating semiconducting and spintronic technologies in AFMs. SIO is a particularly favorable material for exploring this path since its semiconducting nature is entangled with the AFM order and strong spin-orbit coupling. For the observation of the low-field Ohmic AMR in SIO we prepared an epitaxial heterostructure comprising a nano-scale SIO film on top of an epilayer of a FM metal La2/3Sr1/3MnO3 (LSMO). This allows the magnetic field control of the orientation of AFM spins in SIO via the exchange spring effect at the FM-AFM interface.

description: The mammalian cochlea is a complex macroscopic structure due to its helical shape and the microscopic arrangements of the individual layers of cells. To improve the outcomes of hearing restoration in deaf patients, it is important to understand the anatomic structure and composition of the cochlea ex vivo. Hitherto, only one histological technique based on confocal laser scanning microscopy and optical clearing has been developed for in toto optical imaging of the murine cochlea. However, with a growing size of the specimen, e.g., human cochlea, this technique reaches its limitations. Here, we demonstrate scanning laser optical tomography (SLOT) as a valuable imaging technique to visualize the murine cochlea in toto without any physical slicing. This technique can also be applied in larger specimens up to cm3 such as the human cochlea. Furthermore, immunolabeling allows visualization of inner hair cells (otoferlin) or spiral ganglion cells (neurofilament) within the whole cochlea. After image reconstruction, the 3D dataset was used for digital segmentation of the labeled region. As a result, quantitative analysis of position, length and curvature of the labeled region was possible. This is of high interest in order to understand the interaction of cochlear implants (CI) and cells in more detail. © 2017 Nolte et al.This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

description: The quality and crystallinity of ultrathin dielectric layers depend crucially on the details of interface formation and chemical stability. Using a combination of photoelectron (XPS) and electron-energy-loss spectroscopy, low-energy electron-diffraction, and transmission electron microscopy (TEM), we show that crystalline epitaxial layers of Ba2SiO4 can be grown on Si(100) substrates from evaporated Ba in oxygen background atmosphere at 650 °C. Since the silicate is chemically by far more stable than the oxides of Si and Ba, an atomically sharp interface with no interface oxide is formed, as confirmed by XPS and TEM. However, the interface is rough on the atomic scale. dc and frequency-dependent electrical measurements reveal a relative dielectric constant of 22.8, low hysteresis in CV measurements, and low leakage currents but still fairly high interface trap densities. © 2016 American Physical Society.

description: Integration of cultural knowledges and healing practices with Western medical approaches to alcohol care has been reported for residential and community settings. However, there is little evidence on how culture features in alcohol care in primary health settings. We analysed data from semi-structured interviews (from a broader study) with 17 First Nations Australian staff (n=8 men, n=9 women) from 11 Aboriginal and Torres Strait Islander Community Controlled Health Services. We used grounded theory and the 8-ways Aboriginal pedagogy in analysis. We describe three key themes: 1) interpersonal processes; 2) a both-ways approach to healing and alcohol care; and 3) service-wide strategies to achieving both-ways healing. We discuss policy implications of facilitating bicultural alcohol care in primary health settings.

The method, already used for a contact interacting gas, is extended here to samples with a weakly interacting long-range inter-atomic potential. We present statistical properties of the system for the current experiment with Chromium [Phys. Rev. A 84 053601 (2011)] and compare them with statistics for atoms with larger magnetic dipole moments. Significant enhancement of the third order correlation function, relevant for the particle losses, is found.

In recent years, the Magic Set method has received some interest in this setting, and a variant of it, called DMS, has been proposed for ASP. However, this technique has a caveat, because it is not correct (in the sense of being query-equivalent) for all ASP programs. In recent work, a large fragment of ASP programs, referred to as super-coherent programs, has been identified, for which DMS is correct. The fragment contains all programs which possess at least one answer set, no matter which set of facts is added to them. Two open question remained: How complex is it to determine whether a given program is super-coherent? Does the restriction to super-coherent programs limit the problems that can be solved? Especially the first question turned out to be quite difficult to answer precisely. In this paper, we formally prove that deciding whether a propositional program is super-coherent is Π^P_3-complete in the disjunctive case, while it is Π^P_2-complete for normal programs. The hardness proofs are the difficult part in this endeavor: We proceed by characterizing the reductions by the models and reduct models which the ASP programs should have, and then provide instantiations that meet the given specifications. Concerning the second question, we show that all relevant ASP reasoning tasks can be transformed into tasks over super-coherent programs, even though this transformation is more of theoretical than practical interest.

description: Granulate physics has made considerable progress during the past decades in the understanding of static and dynamic properties of large ensembles of interacting macroscopic particles, including the modeling of phenomena like jamming, segregation and pattern formation, the development of related industrial applications or traffic flow control. The specific properties of systems composed of shape-anisotropic (elongated or flattened) particles have attracted increasing interest in recent years. Orientational order and self-organization are among the characteristic phenomena that add to the special features of granular matter of spherical or irregular particles. An overview of this research field is given.

description: Stellar flares cannot be spatially resolved, which complicates ascertaining the physical processes behind particular spectral signatures. Due to their proximity to Earth, solar flares can serve as a stepping stone for understanding their stellar counterparts, especially when using a Sun-as-a-star instrument and in combination with spatially resolved observations. We aim to understand the disk-integrated spectral behaviors of a confined X2.2 solar flare and its eruptive X9.3 successor as measured by HARPS-N. The behavior of multiple photospheric and chromospheric spectral lines are investigated by means of activity indices and contrast profiles. A number of different photospheric lines were also investigated by means of equivalent widths, and radial velocity measures, which are then related to physical processes directly observed in high-resolution observations made with the Swedish 1-meter Solar Telescope and SDO Our findings suggest a relationship between the evolving shapes of contrast profile time and the flare locations, which assists in constraining flare locations in disk-integrated observations. In addition, an upward bias was found in flare statistics based on activity indices derived from the Ca II H & K lines. In this case, much smaller flares cause a similar increase in the activity index as that produced by larger flares. H$α$-based activity indices do not show this bias and are therefore less susceptible to activity jitter. Sodium line profiles show a strongly asymmetric response during flare activity, which is best captured with a newly defined asymmetrical sodium activity index. A strong flare response was detected in Mn I line profiles, which is unexpected and calls for further exploration. Intensity increases in H$α$, H$β$, and certain spectral windows of AIA before the flare onset suggest their potential use as short-term flare predictors.

description: Als Bereich von Gendergerechtigkeit ist der Nonprofit-Sektor bisher kaum im Blick. Dabei haben viele Nonprofit-Organisationen (NPOs) ihren Ursprung in sozialen Bewegungen, wie der Frauenbewegung. Die umfangreiche Freiwilligenarbeit bildet das gesellschaftliche Unterpfand der Demokratie. Außerdem boomt der Sektor: 3,1 Millionen Menschen sind hier tätig, rund 8 Prozent der Gesamtbeschäftigten und überwiegend Frauen. Zu erwarten wären daher ideale Karrierechancen gerade für sie. Tatsächlich verhält es sich anders.

description: Many cosmological models assume or imply that the total size of the universe is very large, perhaps even infinite. Here we argue instead that the universe might be comparatively small, in fact not much larger than the currently observed size. A concrete implementation of this idea is provided by the no-boundary proposal, in combination with a plateau-shaped inflationary potential. In this model, opposing effects of the weighting of the wave function and of the criterion of allowability of the geometries conspire to favour small universes. We point out that a small size of the universe also fits well with swampland conjectures, and we comment on the relation with the dark dimension scenario.

description: Постановка проблемы. При построении ЛБВ W-диапазона из-за наличия мелкоструктурных элементов и высоких требований к прецизионности (<5 мкм) перестают работать традиционные методы изготовления замедляющих систем (ЗС) ЛБВ сантиметрового диапазона путем сборки и пайки отдельных резонаторов. По этим причинам идут поиски новых конструкций и технологий.
Цель. Разработать новую конструкцию ЗС типа «петляющий волновод» и исследовать ее характеристики.
Результаты. В работе исследована новая конструкция замедляющей системы типа «петляющий волновод» для однолучевой ЛБВ W-диапазона мощностью 60 Вт и усилением 42 дБ при напряжении питания 17.5 кВ. Замедляющая система вместе с узлами ввода/вывода мощности изготавливается с помощью электроэрозионной резки, что минимизирует технологические разбросы.
Практическая значимость. Предложенные конструкция и технология изготовления ЗС и узлов согласования должны обеспечить повышенные электрические параметры и необходимый для промышленного производства выход годных. Данные технические решения могут применяться в ЛБВ для современных военных и гражданских систем локации и связи, метеорадаров, систем радиовидения.

description: The most promising concept for low frequency (millihertz to hertz) gravitational wave observatories are laser interferometric detectors in space. It is usually assumed that the noise floor for such a detector is dominated by optical shot noise in the signal readout. For this to be true, a careful balance of mission parameters is crucial to keep all other parasitic disturbances below shot noise. We developed a web application that uses over 30 input parameters and considers many important technical noise sources and noise suppression techniques to derive a realistic position noise budget. It optimizes free parameters automatically and generates a detailed report on all individual noise contributions. Thus one can easily explore the entire parameter space and design a realistic gravitational wave observatory. In this document we describe the different parameters, present all underlying calculations, and compare the final observatory's sensitivity with astrophysical sources of gravitational waves. We use as an example parameters currently assumed to be likely applied to a space mission proposed to be launched in 2034 by the European Space Agency. The web application itself is publicly available on the Internet at http://spacegravity.org/designer. Future versions of the web application will incorporate the frequency dependence of different noise sources and include a more detailed model of the observatory's residual acceleration noise.

description: An interesting class of background field configurations in QED are the O(2)xO(3) symmetric fields. Those backgrounds have some instanton-like properties and yield a one-loop effective action that is highly nontrivial but amenable to numerical calculation, for both scalar and spinor QED. Here we use the recently developed "partial-wave-cutoff method" for a numerical analysis of both effective actions in the full mass range. In particular, at large mass we are able to match the asymptotic behavior of the physically renormalized effective action against the leading two mass levels of the inverse mass (or heat kernel) expansion. At small mass we obtain good numerical results even in the massless case for the appropriately (unphysically) renormalized effective action after the removal of the chiral anomaly term through a small radial cutoff factor. In particular, we show that the effective action after this removal remains finite in the massless limit, which also provides indirect support for M. Fry's hypothesis that the QED effective action in this limit is dominated by the chiral anomaly term.

description: Постановка проблемы. В настоящее время колонный графен является одним из перспективных углеродных материалов для разработки радиоэлектронных компонентов современных устройств. Важной задачей на пути развития электроники на базе колонного графена является поиск эффективных способов управления электронными свойствами и электронно-энергетическими характеристиками материала. Одним из традиционных способов изменения электронных свойств углеродных материалов является модификация их атомного строения атомами щелочных металлов, в том числе калия. Наличие в структуре колонного графена большого числа полостей открывает широкие возможности управления его свойствами путем заполнения имеющихся пустот различными атомами и соединениями, однако для этого необходимы детальные исследования.
Цель. Исследовать закономерности влияния атомов калия на электронное строение и трансфер заряда пленочных и 3D структур колонного графена.
Результаты. Для атомистических моделей моно- и бислойных пленок, а также 3D-структур колонного графена, построенных на основе однослойных углеродных нанотрубок с индексами киральности (9,9), рассчитаны распределения плотности электронных состояний (DOS) при различных массовых долях калия в полостях колонного графена. Выполнен анализ процесса перетекания заряда в структуре колонного графена, заполненного атомами калия с различной массовой долей. Выявлены закономерности перетекания заряда и распределения DOS колонного графена в зависимости от плотности расположения нанотрубок в его составе.
Практическая значимость. Установленные в работе физические закономерности могут быть использованы для разработки эффективного способа управления электронными свойствами колонного графена путем варьирования топологией материала и массовой долей заполняющих его полости атомов калия.

description: The Network for the Detection of Atmospheric Composition Change (NDACC) is an international global network of more than 90 stations making high-quality measurements of atmospheric composition that began official operations in 1991 after 5 years of planning. Apart from sonde measurements, all measurements in the network are performed by ground-based remote-sensing techniques. Originally named the Network for the Detection of Stratospheric Change (NDSC), the name of the network was changed to NDACC in 2005 to better reflect the expanded scope of its measurements. The primary goal of NDACC is to establish long-term databases for detecting changes and trends in the chemical and physical state of the atmosphere (mesosphere, stratosphere, and troposphere) and to assess the coupling of such changes with climate and air quality. NDACC's origins, station locations, organizational structure, and data archiving are described. NDACC is structured around categories of ground-based observational techniques (sonde, lidar, microwave radiometers, Fourier-transform infrared, UV-visible DOAS (differential optical absorption spectroscopy)-type, and Dobson-Brewer spectrometers, as well as spectral UV radiometers), timely cross-cutting themes (ozone, water vapour, measurement strategies, cross-network data integration), satellite measurement systems, and theory and analyses. Participation in NDACC requires compliance with strict measurement and data protocols to ensure that the network data are of high and consistent quality. To widen its scope, NDACC has established formal collaborative agreements with eight other cooperating networks and Global Atmosphere Watch (GAW). A brief history is provided, major accomplishments of NDACC during its first 25 years of operation are reviewed, and a forward-looking perspective is presented. © 2018 Copernicus GmbH.
