description: We present measurements of the intergalactic medium (IGM) temperature within ~5 proper Mpc of seven luminous quasars at z~6. The constraints are obtained from the Doppler widths of Lyman-alpha absorption lines in the quasar near-zones and build upon our previous measurement for the z=6.02 quasar SDSS J0818+1722. The expanded data set, combined with an improved treatment of systematic uncertainties, yields an average temperature at the mean density of log (T_0/K) = 4.21 \pm 0.03 (\pm^0.06_0.07) at 68 (95) per cent confidence for a flat prior distribution over 3.2 < log (T_0/K) < 4.8. In comparison, temperatures measured from the general IGM at z~5 are ~0.3 dex cooler, implying an additional source of heating around these quasars which is not yet present in the general IGM at slightly lower redshift. This heating is most likely due to the recent reionisation of He-II in vicinity of these quasars, which have hard, non-thermal ionising spectra. The elevated temperatures may therefore represent evidence for the earliest stages of He-II reionisation in the most biased regions of the high-redshift Universe. The temperature as a function of distance from the quasars is consistent with being constant, log(T_0/K)~4.2, with no evidence for a line-of-sight thermal proximity effect. However, the limited extent of the quasar near-zones prevents the detection of He-III regions larger than ~5 proper Mpc. Under the assumption the quasars have reionised the He-II in their vicinity, we infer the data are consistent with an average optically bright phase of duration in excess of 10^6.5 yr. These measurements represent the highest-redshift IGM temperature constraints to date, and thus provide a valuable data set for confronting models of H-I reionisation.

description: Early November 2010, the LHC collided for the first time heavy ions, Pb on Pb, at a centre-of-mass energy of 2.76 TeV/nucleon. This date marked both the end of almost 20 years of preparing for nuclear collisions at the LHC, as well as the start of a new era in ultra-relativistic heavy ion physics at energies exceeding previous machines by more than an order of magnitude. This contribution summarizes some of the early results from all three experiments participating in the LHC heavy ion program (ALICE, ATLAS, and CMS), which show that the high density matter created at the LHC, while much hotter and larger, still behaves like the very strongly interacting, almost perfect liquid discovered at RHIC. Some surprising and even puzzling results are seen in particle ratios, jet-quenching, and Quarkonia suppression observables. The overall experimental conditions at the LHC, together with its set of powerful and state-of-the-art detectors, should allow for precision measurements of quark-gluon-plasma parameters like viscosity and opacity.

description: Fetal growth restriction (FGR) occurs when the placenta does not deliver enough oxygen and nutrients to the developing fetus, leading to an increased risk of respiratory and cardiovascular problems in later life. The brainstem cardiorespiratory centres (BCRC) play an important role in the fetus adapting to hypoxia by redistributing blood flow to essential organs. The aim of this PhD project was to investigate how FGR affects the development of the BCRC in the brainstem, using an ovine model. The study found that FGR caused impaired development of the BCRC, which may lead to functional deficits in cardiovascular and respiratory control. These findings could help inform future interventions to improve outcomes for FGR infants.

description: We present a time-dependent study of electron transport through a strongly correlated quantum dot. The time-dependent current is obtained with the multiple-probe battery method, while adiabatic lattice density functional theory in the Bethe ansatz local-density approximation to the Hubbard model describes the dot electronic structure. We show that for a certain range of voltages the quantum dot can be driven into a dynamical state characterized by regular current oscillations. This is a manifestation of a recently proposed dynamical picture of Coulomb blockade. Furthermore, we investigate how the various approximations to the electron-electron interaction affect the line-shapes of the Coulomb peaks and the I-V characteristics. We show that the presence of the derivative discontinuity in the approximate exchange-correlation potential leads to significantly different results compared to those obtained at the simpler Hartree level of description. In particular, a negative differential conductance (NDC) in the I-V characteristics is observed at large bias voltages and large Coulomb interaction strengths. We demonstrate that such NDC originates from the combined effect of electron-electron interaction in the dot and the finite bandwidth of the electrodes.

Чтобы снизить урон, нанесенный человеком на Землю, нужно, чтобы больше людей были подкованы в вопросах экологического просвещения. Жители мегаполисов и городов-миллионников из-за суеты жизни редко задумываются
о том, что происходит с планетой, что угрожает населению планеты, если не прекратится вредительство над живой природой. В малых городах и деревнях всё обстоит иначе, они намного ближе находятся к природным богатствам, но, несмотря на это, не каждый знает, как сохранить и сберечь то разнообразие, которое они
наблюдают. Именно для этого сейчас стараются ввести во все сферы жизни такое понятие, как экологическое просвещение, для того чтобы это стало привычным как для ребенка, так и для взрослого поколения. Реклама – неотъемлемая часть жизни человека; мы сталкиваемся с ней во всех сферах жизни. В статье она рассматривается как возможный инструмент для экологического просвещения.

description: In spin-1/2 one-dimensional Heisenberg antiferromagnets and anisotropic triangular Heisenberg antiferromagnets, high-energy states carrying considerable spectral weights have been observed in a magnetic field using inelastic neutron scattering. Such high-energy properties cannot be explained in terms of either Nambu-Goldstone bosons due to spontaneous breaking of continuous symmetries or quasiparticles in a Tomonaga-Luttinger liquid. Here, we show that the mechanism causing the high-energy states is analogous to that of the upper Hubbard band in the one-dimensional Hubbard model, by theoretically tracing the origin of the high-energy states back to string solutions of the Bethe ansatz.

description: Развитие рекреации и туризма может являться перспективным направлением для экономики как отдельных регионов, так и страны в целом. С другой стороны, в соответствии с целями устойчивого развития, рекреационное использование территорий не должно снижать их природную ценность. Повсеместное использование количественных методик определения предельных допустимых рекреационных нагрузок на территорию, принятых в качестве основных в нашей стране ещё в 70–80-е гг. XX века, до сих пор сдерживается недостаточным унифицированием единиц, методов и даже базовых понятий в системе оценки рекреационных нагрузок. Традиционный количественный подход должен дополняться либо заменяться подходом, выражающимся в определении качественных пределов допустимых изменений ландшафтов. Закономерным итоговым выражением этого нового подхода является комплекс решений в системе управления особо охраняемой природной территорией (ООПТ), способствующий не только сохранению её экологического
значения, но и развитию туристического рекреационного потенциала. Нормирование по методикам предельно допустимых рекреационных нагрузок (ПДРН) и предельно  допустимых изменений ландшафта (ПДИ) производится на примере экологических троп «Бобровая» и «Иваньи перелески» Валдайского национального парка.

description: The flexoelectric conversion of mechanical to electrical energy in nematic liquid crystals is investigated using continuum theory. Since the electrical energy produced cannot exceed the mechanical energy supplied, and vice-versa, upper bounds are imposed on the magnitudes of the flexoelectric coefficients in terms of the elastic and dielectric coefficients. For conventional values of the elastic and dielectric coefficients, it is shown that the flexoelectric coefficients may not be larger than a few tens of pC/m. This has important consequences for the future use of such flexoelectric materials in devices and the related energetics of distorted equilibrium structures.

description: The study is from a base of accident scenarii in rail transport (feedback) in order to develop a tool to share build and sustain knowledge and safety and secondly to exploit the knowledge stored to prevent the reproduction of accidents / incidents. This tool should ultimately lead to the proposal of prevention and protection measures to minimize the risk level of a new transport system and thus to improve safety. The approach to achieving this goal largely depends on the use of artificial intelligence techniques and rarely the use of a method of automatic learning in order to develop a feasibility model of a software tool based on case based reasoning (CBR) to exploit stored knowledge in order to create know-how that can help stimulate domain experts in the task of analysis, evaluation and certification of a new system.

description: Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality worldwide, but our understanding of its cause, progression and likely outcomes remains limited. This thesis examines how maternal characteristics influence the diagnosis and prognosis of preeclampsia. We found that women who are more likely to be diagnosed with preeclampsia, due to pre-existing comorbidities such as hypertension or obesity, often had better outcomes than did women who began pregnancy at low-risk of developing the disease. This is likely a result of unnecessary diagnosis and intervention for women with risk factors, indicating a need to review how we diagnose preeclampsia.

description: Abstract Halide perovskites have undergone an impressive development and could be used in a wide range of optoelectronic devices, where some of them are already at the edge of commercialization, e.g., perovskite solar cells. Recently, interest in perovskites in powder form has increased, as for example, they are found to exhibit high stability and allow for easy production of large quantities. Accordingly, also the topic of processing thin and thick films on the basis of perovskite powders is currently gaining momentum. Here, perovskite powder can form the basis for both, typical wet and solvent-based processing approaches, as well as for dry processes. In this Progress Report, the recent developments of halide perovskites in powder form and of film processing approaches are summarized that are based on them. The advantages and opportunities of the different processing methods are highlighted, but their individual drawbacks and limitations are also discussed. Prospects are also pointed out and possible steps necessary to unlock the full potential of powder-based processing methods for producing high quality thick and thin perovskite layers in the future are discussed.
Creatine metabolism in human pregnancy and the potential for oral creatine supplementation in pregnancy

subject: Other health sciences not elsewhere classified

description: Globally, 4 million neonatal deaths occur annually. Many occur as a result of an acute low oxygen event to the fetus during labour or birth (intrapartum asphyxia). Currently, no oral therapy can minimise the impact of these unpredictable events. Maternal creatine supplementation during pregnancy could support ongoing cellular energy production and safeguard fetal organs from harm due to low oxygen. Although pre-clinical laboratory science is strong, further questions need to be answered, before progressing to human clinical trials. This thesis details the identified gaps in our knowledge and the translational research work undertaken to inform future pregnancy clinical trials.

description: We use high time cadence images acquired by the STEREO EUVI and COR instruments to study the evolution of coronal mass ejections (CMEs), from their initiation, through the impulsive acceleration to the propagation phase. For a set of 95 CMEs we derived detailed height, velocity and acceleration profiles and statistically analysed characteristic CME parameters: peak acceleration, peak velocity, acceleration duration, initiation height, height at peak velocity, height at peak acceleration and size of the CME source region. The CME peak accelerations derived range from 20 to 6800 m s^2 and are inversely correlated to the acceleration duration and to the height at peak acceleration. 74% of the events reach their peak acceleration at heights below 0.5 Rsun. CMEs which originate from compact sources low in the corona are more impulsive and reach higher peak accelerations at smaller heights. These findings can be explained by the Lorentz force, which drives the CME accelerations and decreases with height and CME size.

description: The broad emission spectral lines emitted from AGNs are our main probe of the geometry and physics of the broad line region (BLR) close to the SMBH. There is a group of AGNs that emits very broad and complex line profiles, showing two displaced peaks, one blueshifted and one redshifted from the systemic velocity defined by the narrow lines, or a single such peak. It has been proposed that such line shapes could indicate a supermassive binary black hole (SMB) system. We discuss here how the presence of an SMB will affect the BLRs of AGNs and what the observational consequences might be. We review previous claims of SMBs based on broad line profiles and find that they may have non-SMB explanations as a consequence of a complex BLR structure. Because of these effects it is very hard to put limits on the number of SMBs from broad line profiles. It is still possible, however, that unusual broad line profiles in combination with other observational effects (line ratios, quasi-periodical oscillations, spectropolarimetry, etc.) could be used for SMBs detection. Some narrow lines (e.g., [O\,III]) in some AGNs show a double-peaked profile. Such profiles can be caused by streams in the Narrow Line Region (NLR), but may also indicate the presence of a kilo-parsec scale mergers. A few objects indicated as double-peaked narrow line emitters are confirmed as kpc-scale margers, but double-peaked narrow line profiles are mostly caused by the complex NLR geometry. We briefly discuss the expected line profile of broad Fe K$α$ that probably originated in the accretion disk(s) around SMBs. Finally we consider rare configurations where a SMB system might be gravitationally lensed by a foreground galaxy, and discuss the expected line profiles in these systems.

description: Mean profiles are widely used as indicators of the electricity consumption habits of customers. Currently, in Électricité De France (EDF), class load profiles are estimated using point-wise mean function. Unfortunately, it is well known that the mean is highly sensitive to the presence of outliers, such as one or more consumers with unusually high-levels of consumption. In this paper, we propose an alternative to the mean profile: the $L_1$-median profile which is more robust. When dealing with large datasets of functional data (load curves for example), survey sampling approaches are useful for estimating the median profile avoiding storing the whole data. We propose here estimators of the median trajectory using several sampling strategies and estimators. A comparison between them is illustrated by means of a test population. We develop a stratification based on the linearized variable which substantially improves the accuracy of the estimator compared to simple random sampling without replacement. We suggest also an improved estimator that takes into account auxiliary information. Some potential areas for future research are also highlighted.

Results suggest that NSCs hold therapeutic potential as a treatment to alleviate life-long impacts associated with damage to the young brain.

description: Higher derivative scalar field theories have received considerable attention for the potentially explanations of the initial state of the universe or the current cosmic acceleration which they might offer. They have also attracted many interests in the phenomenological studies of infrared modifications of gravity. These theories are mostly studied by the metric variational approach in which only the metric is the fundamental field to account for the gravitation. In this paper we study the higher derivative scalar fields with the metric-affine formalism where the connections are treated arbitrarily at the beginning. Because the higher derivative scalar fields couple to the connections directly in a covariant theory these two formalisms will lead to different results. These differences are suppressed by the powers of the Planck mass and are usually expected to have small effects. But in some cases they may cause non-negligible deviations. We show by a higher derivative dark energy model that the two formalisms lead to significantly different pictures of the future universe.

description: Discovery of menstruation in spiny mouse provides new directions in women’s reproductive health research. In women, obesity and poly cystic ovary syndrome (PCOS) are linked resulting in infertility. My studies tested this link using spiny mice: In Study 1 a high caloric diet did not cause excessive weight gain or change the menstrual cycle suggesting a protective mechanism prevented this. In Study 2, letrozole treatment was used to induce PCOS, but, unlike other rodents, no PCOS symptoms and no change in menstrual cycles were observed. These studies confirm that spiny mice are not typical rodents in their responses to these experimental treatments.

description: Background

With the next generation of Human Epidermal Growth Factor Receptor 2 (HER2) -targeting therapies, such as antibody–drug conjugates, showing benefit in “HER2 low” and even “HER2 ultralow” patients, the need for novel methods to quantify HER2 expression accurately becomes even more important for clinical decision making. A HER2 PET/CT imaging assessment could evaluate HER2 positive disease locations while improving patient care, reducing the need for invasive biopsies. A single-domain antibody (sdAb)-based PET tracer could combine the high specificity of sdAbs with short-lived radionuclides such as fluorine-18 (18F) and gallium-68 (68Ga). SdAb-based PET tracers have clinically been used via a 68Ga-chelator approach. However, the distribution of 68Ga-labelled pharmaceuticals to peripheral PET centres is more challenging to organize due to the short half-life of 68Ga, most certainly when the available activity is limited by a generator. Cyclotron produced 68Ga has removed this limitation. Distribution of 18F-labelled pharmaceuticals remains less challenging due to its slightly longer half-life, and radiofluorination of sdAbs via N-succinimidyl-4-[18F]fluorobenzoate ([18F]SFB) has shown to be a promising strategy for developing sdAb-based PET tracers. Although [18F]SFB automation has been reported, automating protein conjugation proves challenging. Herein we report the fully automated, cartridge-based production of [18F]FB-HER2 sdAb on a single synthesis module.

Results

[18F]FB-HER2 sdAb (> 6 GBq) was obtained after a fully automated production (95 min), with a RCP > 95%, apparent molar activity > 20 GBq/µmol and decay-corrected radiochemical yield (RCY d.c.) of 14 ± 2% (n = 4). Further upscaling amounted to production batches of 16 GBq with an apparent molar activity > 40 GBq/µmol and RCY d.c. of 8 ± 1% (n = 4). Ex vivo biodistribution and PET imaging showed specific HER2-positive tumour targeting and low kidney retention.

Conclusion

The [18F]FB-HER2 sdAb tracer was produced with clinically relevant activities using a fully automated production method. The automated production method was designed to ease the translation to the clinic and has the potential to be used not only in mono-centre but also multi-centre clinical trials with one central production site. [18F]FB-HER2 sdAb showed a favourable biodistribution pattern and could be a valuable alternative to 68Ga-labelled sdAb-based PET tracers in the clinic.

description: Birth asphyxia, a perinatal state of critically reduced blood supply and oxygen tension, is associated with severe multi-organ damage. My research examined the effects of birth asphyxia on ovarian function, and especially the number of follicles in the ovary, in the spiny mouse. The study highlighted the protective effect of creatine treatment during pregnancy on the ovarian reserve after birth asphyxia and provides a new and exciting understanding of the development and function of the ovary after oxygen deprivation at birth. A subsequent clinical study showed links between birth stress and premature ovarian failure in women suggesting a potential treatment.
MoS2 Nanoribbon Transistors: Transition from Depletion-mode to Enhancement-mode by Channel Width Trimming

description: We study the channel width scaling of back-gated MoS2 metal-oxide-semiconductor field-effect transistors (MOSFETs) from 2 μm down to 60 nm. We reveal that the channel conductance scales linearly with channel width, indicating no evident edge damage for MoS2 nanoribbons with widths down to 60 nm as defined by plasma dry etching. However, these transistors show a strong positive threshold voltage (VT) shift with narrow channel widths of less than 200 nm. Our results also show that transistors with thinner channel thicknesses have larger VT shifts associated with width scaling. Devices fabricated on a 6 nm thick MoS2 crystal underwent the transition from depletion-mode to enhancement-mode.

description: This research paper emphasizes that the Stable Matching problems are the same as the problems of stable configurations of Multi-stage Interconnection Networks (MIN). The authors have solved the Stability Problem of Existing Regular Gamma Multi-stage Interconnection Network (GMIN), 3-Disjoint Gamma Multi-stage Interconnection Network (3DGMIN) and 3-Disjoint Path Cyclic Gamma Multi-stage Interconnection Network (3DCGMIN) using the approaches and solutions provided by the Stable Matching Problem. Specifically Stable Marriage Problem is used as an example of Stable Matching. For MINs to prove Stable two existing algorithms are used:-the first algorithm generates the MINs Preferences List in time and second algorithm produces a set of most Optimal Pairs of the Switching Elements (SEs) (derived from the MINs Preferences List) in time. Moreover, the paper also solves the problem of Ties that occurs between the Optimal Pairs. The results are promising as the comparison of the MINs based on their stability shows that the ASEN, ABN, CLN, GMIN, 3DCGMIN are highly stable in comparison to HZTN, QTN, DGMIN. However, on comparing the irregular and regular MINs in totality upon their stability the regular MINs comes out to be more stable than the irregular MINs.

description: Preeclampsia is a syndrome of pregnancy characterised by high blood pressure and organ dysfunction. It is an important cause of maternal and perinatal death and morbidity and in the long term is associated with an increased risk of heart disease. In this thesis, we have sought to re-evaluate the current definitions used in preeclampsia and our approach to prognostication of disease through shifting the focus from disease diagnosis to disease outcomes.

description: Very energetic cosmic rays entering the atmosphere of the Earth will create a plasma cloud moving with almost the speed of light. The magnetic field of the Earth induces an electric current in this cloud which is responsible for the emission of coherent electromagnetic radiation. We propose to search for a new effect: due to the index of refraction of air this radiation is collimated in a Cherenkov cone. To express the difference from usual Cherenkov radiation, i.e. the emission from a fast moving electric charge, we call this magnetically-induced Cherenkov radiation. We indicate its signature and possible experimental verification.

description: We consider a class of self-adjoint extensions using the boundary triple technique. Assuming that the associated Weyl function has the special form $M(z)=\big(m(z)\Id-T\big) n(z)^{-1}$ with a bounded self-adjoint operator $T$ and scalar functions $m,n$ we show that there exists a class of boundary conditions such that the spectral problem for the associated self-adjoint extensions in gaps of a certain reference operator admits a unitary reduction to the spectral problem for $T$. As a motivating example we consider differential operators on equilateral metric graphs, and we describe a class of boundary conditions that admit a unitary reduction to generalized discrete laplacians.

description: We consider a task graph to be executed on a set of processors. We assume that the mapping is given, say by an ordered list of tasks to execute on each processor, and we aim at optimizing the energy consumption while enforcing a prescribed bound on the execution time. While it is not possible to change the allocation of a task, it is possible to change its speed. Rather than using a local approach such as backfilling, we consider the problem as a whole and study the impact of several speed variation models on its complexity. For continuous speeds, we give a closed-form formula for trees and series-parallel graphs, and we cast the problem into a geometric programming problem for general directed acyclic graphs. We show that the classical dynamic voltage and frequency scaling (DVFS) model with discrete modes leads to a NP-complete problem, even if the modes are regularly distributed (an important particular case in practice, which we analyze as the incremental model). On the contrary, the VDD-hopping model leads to a polynomial solution. Finally, we provide an approximation algorithm for the incremental model, which we extend for the general DVFS model.

description: Dark Matter direct detection experiments are able to exclude interesting parameter space regions of particle models which predict an important amount of thermal relics. We use recent data to constrain the branon model and to compute the region that is favored by CDMS measurements. Within this work, we also update present colliders constraints with new studies coming from the LHC. Despite the present low luminosity, it is remarkable that for heavy branons, CMS and ATLAS measurements are already more constraining than previous analyses performed with TEVATRON and LEP data.
