description: The properties of interstellar grains, such as grain size distribution and grain porosity, are affected by interstellar processing, in particular, coagulation and shattering, which take place in the dense and diffuse interstellar medium (ISM), respectively. In this paper, we formulate and calculate the evolution of grain size distribution and grain porosity through shattering and coagulation. For coagulation, we treat the grain evolution depending on the collision energy. Shattering is treated as a mechanism of forming small compact fragments. The balance between these processes are determined by the dense-gas mass fraction $η_\mathrm{dense}$, which determines the time fraction of coagulation relative to shattering. We find that the interplay between shattering supplying small grains and coagulation forming porous grains from shattered grains is fundamentally important in creating and maintaining porosity. The porosity rises to 0.7--0.9 (or the filling factor 0.3--0.1) around grain radii $a\sim 0.1~μ$m. We also find that, in the case of $η_\mathrm{dense}=0.1$ (very efficient shattering with weak coagulation) porosity significantly enhances coagulation, creating fluffy submicron grains with filling factors lower than 0.1. The porosity enhances the extinction by 10--20 per cent at all wavelengths for amorphous carbon and at ultraviolet wavelengths for silicate. The extinction curve shape of silicate becomes steeper if we take porosity into account. We conclude that the interplay between shattering and coagulation is essential in creating porous grains in the interstellar medium and that the resulting porosity can impact the grain size distributions and extinction curves.

description: We extract the shear viscosity to entropy density ratio η/s of cold fermionic atoms in the unitarity limit from experimental data on the damping of collective excitations. We find that near the critical temperature η/s is roughly equal to 1/2 in units of \hbar/k_B. With the possible exception of the quark gluon plasma, this value is closer to the conjectured lower bound 1/(4π) than any other known liquid.

description: Numerical relativity simulations provide the most precise templates for the gravitational waves produced by binary black hole mergers. However, many of these simulations use an incomplete waveform extraction technique -- extrapolation -- that fails to capture important physics, such as gravitational memory effects. Cauchy-characteristic evolution (CCE), by contrast, is a much more physically accurate extraction procedure that fully evolves Einstein's equations to future null infinity and accurately captures the expected physics. In this work, we present a new surrogate model, NRHybSur3dq8$\_$CCE, built from CCE waveforms that have been mapped to the post-Newtonian (PN) BMS frame and then hybridized with PN and effective one-body (EOB) waveforms. This model is trained on 102 waveforms with mass ratios $q\leq8$ and aligned spins $χ_{1z}, \, χ_{2z} \in \left[-0.8, 0.8\right]$. The model spans the entire LIGO-Virgo-KAGRA (LVK) frequency band (with $f_{\text{low}}=20\text{Hz}$) for total masses $M\gtrsim2.25M_{\odot}$ and includes the $\ell\leq4$ and $(\ell,m)=(5,5)$ spin-weight $-2$ spherical harmonic modes, but not the $(3,1)$, $(4,2)$ or $(4,1)$ modes. We find that NRHybSur3dq8$\_$CCE can accurately reproduce the training waveforms with mismatches $\lesssim2\times10^{-4}$ for total masses $2.25M_{\odot}\leq M\leq300M_{\odot}$ and can, for a modest degree of extrapolation, capably model outside of its training region. Most importantly, unlike previous waveform models, the new surrogate model successfully captures memory effects.

description: We present maps for the electron temperature in the inner kpc of three luminous Seyfert galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini GMOS-IFU observations at spatial resolutions of 110-280 pc. We study the distributions of electron temperature in active galaxies and find temperatures varying in the range from 8000 to >30000 K. Shocks due to gas outflows play an important role in the observed temperature distributions of Mrk 79 and Mrk 348, while standard photoionization models reproduce the derived temperature values for Mrk 607. In Mrk 79 and Mrk 348, we find direct evidence for shock-ionization with overall orientation orthogonal to the ionization axis, where shocks can be easily observed as the AGN radiation field is shielded by the nuclear dusty torus. This also indicates that even when the ionization cones are narrow, the shocks can be much wider-angle.

Two opinions dynamics generated by inflexibles and non-contrarian and contrarian floaters

description: We assume a community whose members adopt one of two opinions $A$ or $B$. Each member appears as an inflexible, or as a non-contrarian or contrarian floater. An inflexible sticks to its opinion, whereas a floater may change into a floater of the alternative opinion. The occurrence of this change is governed by the local majority rule: members meet in groups of a fixed size, and a floater then changes its opinion provided it is a minority in the group. Subsequently, a non-contrarian floater keeps the opinion as adopted under the local majority rule, whereas a contrarian floater adopts the alternative opinion. Whereas the effects of on the one hand inflexibles and on the other hand non-contrarians and contrarians have previously been studied seperately, the current approach allows us to gain insight in the effect of their combined presence in a community. Given fixed proportions of inflexibles $(α_{A}, α_{B})$ for the two opinions, and fixed fractions of contrarians $(γ_{A}, γ_{B})$ among the $A$ and $B$ floaters, we derive the update equation $p_{t+1}$ for the overall support for opinion $A$ at time $t+1$, given $p_{t}$. The update equation is derived respectively for local group sizes 1, 2 and 3. The associated dynamics generated by repeated local updates is then determined to identify its asymptotic steady configuration. The full opinion flow diagram is thus obtained, showing conditions in terms of the parameters for each opinion to eventually win the competing dynamics. Various dynamical scenarios are thus exhibited, and it is derived that relatively small densities of inflexibles allow for more variation in the qualitative outcome of the dynamics than higher densities of inflexibles.

Environment Canada’s environmental choice program (ECP) : using information about the way consumers think about the ecologo to increase the program’s utility for consumers
Creators: name: Bartman, Celeste Camille
Publisher: name: University of British Columbia
Year: 2009

description: Environment Canada's Environmental Choice Program (ECP) was officially announced in June of 1988. Its purpose is to help consumers find products and services that reduce the burden on the environment. Companies can apply to have a product certified with the EcoLogo where appropriate guidelines exist. The EcoLogo symbol takes the form of three doves intertwined into a maple leaf with the accompanying words: "Environmental Choice". A 1994 poll conducted for the ECP found that only 37% of Canadians have some level of either aided or unaided awareness of the EcoLogo (Environics Research Group Limited, p.10). The purpose of this thesis is to investigate how consumers think about and respond to the EcoLogo in the hope that the insights gained will be used to tailor the program to better inform consumers. Specifically, answers are sought to three research questions: 1) are there any consumer characteristics that help explain low recognition of the EcoLogo, 2) what is consumer understanding of the EcoLogo, EcoLogo products and the EcoLogo Program, and 3) what do consumers need to make the EcoLogo program a credible source of environmental information to act on. The methods used to investigate this topic included two focus groups, forty structured interviews, inquiries to relevant programs and a library search. Three consumer traits were found to be impediments to consumer recognition of the EcoLogo: the frequency with which consumers comparison shop, the detail to which consumers read product labels, and overriding consideration for non-ecological product traits. Consumers understand the EcoLogo represents a connection with the environment; however, they lack the knowledge that the Canadian government is responsible for the EcoLogo. Consumers need additional help in three areas: understanding the environmental information found on products, accessing information that gives the EcoLogo credibility, and accessing information about quality, performance and safety of EcoLogo products. These are referred to as "unheard messages". A three step recommendation process i s made to the ECP. First, licensees should be informed of all relevant research results. Second, the EcoLogo should be made more prominent on products. Third, additional efforts should be made to communicate the three unheard messages.

description: Η θεματολογία της παρούσας διατριβής περιστρέφεται γύρω από το ρόλο της εικόνας στη δημόσια τελετουργία. Βασικός στόχος είναι να παρουσιαστεί η αναλλοίωτη σχέση που έχουμε με τις εικόνες. ευελπιστώ να καταστεί σαφές ότι η σχέση αυτή παραμένει πάντα η ίδια, σε κάθε κοινωνικοπολιτική κατάσταση, γεωγραφική θέση και – κυρίως – εποχή. Τα παραδείγματα που έχουν επιλεχθεί αποτελούν μια σειρά απο αλληλοσυγκρουόμενα ζεύγη. Μέσα απο τα ζεύγη αυτά, αναλύεται η υποδοχή του εκάστοτε κοινού απέναντι σε εικόνες που έφτασαν στο σημείο να θεωρηθούν λατρευτικές, είτε πρόκειται για εικόνες θείων προσώπων είτε για απεικονίσεις κοινών θνητών. Η θέση μου δεν μπορεί να εκφραστεί καλύτερα απ’ ό,τι με τα λόγια του Jacques-Louis David, του ζωγράφου που δημιούργησε μια απο τις πιο σημαντικες θρησκευτικές εικόνες στην ιστορία της εικόνας, τον αξέχαστο Θάνατο του Marat: «οι εικόνες στα μάτια των ανθρώπων είναι θαύματα, που ξαναφέρνουν για πάντα στον κόσμο, όσα πιστεύουμε πως έχουμε χάσει».
description: The subject of the present thesis revolves around the role of images in public ritual. The basic aim is to present the unalterable relationship we have with images. I hope it will be made clear that this relationship always remains the same, in every sociopolitical status, geographical location and – principally – era. The examples selected constitute a series of conflicting pairs. Each public reception of images that came to the point of being treated as holy icons, is analysed through these pairs, be they images of divinity or depictions of mere mortals. My argument cannot be better expressed than in the words of Jacques-Louis David, the painter who created one of the most significant religious icons in the history of images, the unforgettable Death of Marat: “images in the eyes of men are miracles, which forever bring back to the world, what we believe to have lost’’.

description: We study Krylov complexity of a one-dimensional Bosonic system, the celebrated Bose-Hubbard Model. The Bose-Hubbard Hamiltonian consists of interacting bosons on a lattice, describing ultra-cold atoms. Apart from showing superfluid-Mott insulator phase transition, the model also exhibits both chaotic and integrable (mixed) dynamics depending on the value of the interaction parameter. We focus on the three-site Bose Hubbard Model (with different particle numbers), which is known to be highly mixed. We use the Lanczos algorithm to find the Lanczos coefficients and the Krylov basis. The orthonormal Krylov basis captures the operator growth for a system with a given Hamiltonian. However, the Lanczos algorithm needs to be modified for our case due to the instabilities instilled by the piling up of computational errors. Next, we compute the Krylov complexity and its early and late-time behaviour. Our results capture the chaotic and integrable nature of the system. Our paper takes the first step to use the Lanczos algorithm non-perturbatively for a discrete quartic bosonic Hamiltonian without depending on the auto-correlation method.

description: Cygnus X-1, the well-known accreting black hole system, exhibits several observational features hinting at an intricate interplay between the accretion disk, its atmosphere known as the corona and the putative relativistic jet. It has been extensively studied using all available observational methods, including using the newly available technique of sensitive X-ray polarimetry. X-ray polarization characteristics are distinct for coronal and jet emissions. The low X-ray polarization measured below $\sim$100 keV is understood as arising from the corona. In contrast, the high polarization measurements reported above $\sim$400 keV required a separate jet-dominated spectral component, which spectroscopy does not demonstrate conclusively. Here we report precise polarization measurements in the 100-380 keV region made during three different sub-classes of spectral states of the source using the CZTI instrument onboard {\em AstroSat}. A high polarization (23$\pm$4 \%) is found mainly in the Intermediate Hard State of the source, and the energy-resolved measurements smoothly connect the coronal and the jet regimes. When high polarization is observed, the simultaneous spectral data hints at a separate power law component above 100 keV. We examine the possible sources of this energy-dependent high polarization in Cygnus X-1.

Dust surface potential for the dusty plasma with negative ions and with a three-parameter non-Maxwell velocity distribution

description: We study the dust surface potential for the complex dusty plasma with negative ions and with a three-parameter non-Maxwell velocity distribution. The plasma contains electrons, positive ions, negative ions, and negatively charged dust particles. By using the current equilibrium condition, we derive the relationship between the normalized dust surface potential and the dusty plasma parameters such as the normalized dust number density, the temperature ratio of negative ions to electrons, the density ratio of negative ions to positive ions, and the charge number of negative ions. The numerical analyses show that the relationship depends evidently on the three parameters in the non-Maxwell distribution when the dust surface potential is relatively smaller, but with increase of the potential, such dependence will weaken soon. The dust surface potential is negative and increases monotonously with increase of the dust density, and for the complex dusty plasma with the three-parameter non-Maxwell distribution, it is generally greater than that in the same plasma with the kappa-distribution and the Maxwellian distribution.

Gamma Ray Fresnel lenses - why not?
Creators: name: Skinner, G. K.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: Fresnel lenses offer the possibility of concentrating the flux of X-rays or gamma-rays flux falling on a geometric area of many square metres onto a focal point which need only be a millimetre or so in diameter (and which may even be very much smaller). They can do so with an efficiency that can approach 100%, and yet they are easily fabricated and have no special alignment requirements. Fresnel lenses can offer diffraction-limited angular resolution, even in a domain where that limit corresponds to less than a micro second of arc. Given all these highly desirable attributes, it is natural to ask why Fresnel gamma ray lenses are not already being used, or at least why there is not yet any mission that plans to use the technology. Possible reasons (apart from the obvious one that nobody thought of doing so) include the narrow bandwidth of simple Fresnel lenses, their very long focal length, and the problems of target finding. It is argued that none of these is a "show stopper" and that this technique should be seriously considered for nuclear astrophysics.

The antenna design is robust to fabrication imperfections, such as variations in the dimensions of the dielectric perturbations and the emitter dipole location. The field-based dielectric antenna design provides an efficient free-space interface to closely packed arrays of quantum memories for multiplexed quantum repeaters, arrayed quantum sensors, and modular quantum computers.

description: Targeted free energy perturbation uses an invertible mapping to promote configuration space overlap and the convergence of free energy estimates. However, developing suitable mappings can be challenging. Wirnsberger et al. (2020) demonstrated the use of machine learning to train deep neural networks that map between Boltzmann distributions for different thermodynamic states. Here, we adapt their approach to free energy differences of a flexible bonded molecule, deca-alanine, with harmonic biases with different spring centers. When the neural network is trained until ``early stopping'' - when the loss value of the test set increases - we calculate accurate free energy differences between thermodynamic states with spring centers separated by 1 Å and sometimes 2 Å. For more distant thermodynamic states, the mapping does not produce structures representative of the target state and the method does not reproduce reference calculations.

description: Weakly- and Feebly-Interacting Massive Particles (WIMPs and FIMPs) are among the best-motivated dark matter (DM) candidates. In this paper, we investigate the production of DM through the WIMP and FIMP mechanisms during inflationary reheating. We show that the details of the reheating, such as the inflaton potential and the reheating temperature, have a strong impact on the genesis of DM. The strong entropy injection caused by the inflaton decay has to be compensated by a reduction of the portal coupling in the case of WIMPs, or by an increase in the case of FIMPs. We pinpoint the smooth transition between the WIMP and the FIMP regimes in the case of low reheating temperature. As an example, we perform a full numerical analysis of the singlet-scalar DM model; however, our results are generic and adaptable to other particle DM candidates. Interestingly, in the singlet-scalar DM model with low-reheating temperature, regions favored by the FIMP mechanism are already being tested by direct detection experiments such as LZ and XENONnT.

Ülkemizde çoğu zaman bu hastaların yönetimlerinin en zor kısmı; reçetelerine antibiyotik yazılıp yazılmayacağı kararı oluyor. Bu kararın zorluğunun sebebi ise tıbbi gerekçeler veya kılavuzların bilinmiyor olması değil, hasta ve hasta yakınlarının antibiyotik yazılması konusundaki ısrarcı ve bazen de şiddet içeren talepleri oluyor. Her geçen gün artan antibiyotik dirençleri, antibiyotiklerin maliyetleri ve gereksiz kullanıma bağlı yan etki ve zararları sebebiyle, hem ülkemizde hem de tüm dünyada gereksiz antibiyotik kullanımının önüne geçmek için çeşitli bilgilendirme kampanyaları yapılmaktadır. Gereksiz antibiyotik kullanımında en çok bahsi geçen hasta grubu boğaz ağrısı ile acil servise başvuran hastalardır herhalde. Sadece ülkemizde değil birçok ülkede birinci basamak sağlık hizmeti veren kurumda boğaz ağrısı ile gelen hastalara antibiyotik yazılmakta. Örneğin İngiltere’de boğaz ağrısı ile gelen ve birinci basamak sağlık hizmeti alan hastaların %60’ından fazlasına antibiyotik yazılmakta ve yapılan çalışmalar bu yüzdelerin düşme eğiliminde olma

description: We examine how effective-model-space (EMS) calculations of nuclear many-body systems rearrange and converge multi-particle entanglement. The generalized Lipkin-Meshkov-Glick (LMG) model is used to motivate and provide insight for future developments of entanglement-driven descriptions of nuclei. The effective approach is based on a truncation of the Hilbert space together with a variational rotation of the qubits (spins), which constitute the relevant elementary degrees of freedom. The non-commutivity of the rotation and truncation allows for an exponential improvement of the energy convergence throughout much of the model space. Our analysis examines measures of correlations and entanglement, and quantifies their convergence with increasing cut-off. We focus on one- and two-spin entanglement entropies, mutual information, and $n$-tangles for $n=2,4$ to estimate multi-body entanglement. The effective description strongly suppresses entropies and mutual information of the rotated spins, while being able to recover the exact results to a large extent with low cut-offs. Naive truncations of the bare Hamiltonian, on the other hand, artificially underestimate these measures. The $n$-tangles in the present model provide a basis-independent measures of $n$-particle entanglement. While these are more difficult to capture with the EMS description, the improvement in convergence, compared to truncations of the bare Hamiltonian, is significantly more dramatic. We conclude that the low-energy EMS techniques, that successfully provide predictive capabilities for low-lying observables in many-body systems, exhibit analogous efficacy for quantum correlations and multi-body entanglement in the LMG model, motivating future studies in nuclear many-body systems and effective field theories relevant to high-energy physics and nuclear physics.

description: In the paper a realization of representation of a Lie algebra $\mathfrak{sp}_4$ in the space of function on the Lie group $Sp_4$ is considered. We find a function corresponding to a Gelfand-Tsetlin type vector for $\mathfrak{sp}_4$ constructed by D.P. Zhelobenko. This function is expressed though a $A$-hypergeometric function. After developing some new technique we derive analytically formulas for the action of generators of algebra in this base (the were not known before). These formula turn out to be much more difficult than the formulas for the action of generators in the Gelfand-Tsetlin type base constructed by Molev.

description: Aiming at automating the different trades intervening in mechanical parts' design activities, one finds the weakest link within the interface linking the computer aided-design trade (CAD) and the process planning trade (CAPP) where a huge semantic gap is detected. Works generally tends to optimize the pre-process planning trade (design/CAD) and post-process planning trade (machinning/CAM). So as to bridge in between CAD and CAPP we present at first support functions that helps a process planner setting a process plan for an aircraft structural part. The proposed functions will be forwarded in the same order the planner questions himself during his first analysis. Each function is justified by presenting the need behind. We end up on the benefits of having such an assistance tool as we mention the future perspectives of our works.
Hipoglisemide D10 mu D50 mi?

description: Acil servislerde hepimizin çok sık karşılaştığı bir hasta grubu; hipoglisemik, bilinci kapalı hastalardır. Acil servislerimizde bu hastalara yaklaşımımız genellikle kan şekerini agresif bir şekilde yükseltmek şeklindedir. Bilinci açılan hastalar sonrasında bazen yoğun acil servislerimizde göz ardı edilebilmektedir ve takipleri dört dörtlük yapılamamaktadır. Bu yüzden uzun dönem komplikasyonları en az olan tedavi yöntemlerine yönelmek özellikle yoğun acil servislerde akıllıca olacaktır. Bildiğimiz üzere hipoglisemi; kan şekerinin düşüklüğüne bağlı ortaya çıkan otonomik hiperaktivite (anksiyete, irritabilite, palpitasyon) ve/veya nörolojik disfonksiyon (letarji, bilinç bulanıklığı, nöbet, koma) tablosudur. Kan şekeri normal seviyeye döndüğünde kliniğin düzelmesi beklenir. Acil servislerde çok sık karşılaştığımız hipoglisemik hastalar genellikle, insulin veya oral antidiyabetik (OAD) kullanan hastalardır. Bu hasta grubunun %27’si yılda en az bir kez ağır hipoglisemi atağı geçirmektedir (1). Bu atakların tedavisinde IV dekstroz kullanmaktayız ancak yüzde kaçlık dekstroz kullanmamız gerekiyor? %10’luk mu? %50’lik mi? Bence bu konu biraz tartışmalı bir konu. Birçok ana kitap (örn; Adams); erişkinde hipoglisemik atak yönetiminde Tablo-1); oral alamayacak, damar yolu açık hastada 1 ampül sulandırılmış %50 dekstroz (D50W) (25 gr glukoz) önermektedir ve eğer gerekli görülürse 3 kez tekrarlanabileceğini belirtmektedir.

description: A crucial building block for quantum information processing with trapped ions is a controlled-NOT quantum gate. In this paper, two different sequences of laser pulses implementing such a gate operation are analyzed using quantum process tomography. Fidelities of up to 92.6(6)% are achieved for single gate operations and up to 83.4(8)% for two concatenated gate operations. By process tomography we assess the performance of the gates for different experimental realizations and demonstrate the advantage of amplitude--shaped laser pulses over simple square pulses. We also investigate whether the performance of concatenated gates can be inferred from the analysis of the single gates.

description: We investigate non-equilibrium behavior of driven dissipative systems, using the model presented in [Phys. Rev. Lett. 93, 240601 (2004)]. We solve the non-Boltzmann steady state energy distribution and the temporal evolution to it, and find its high energy tail to behave exponentially. We demonstrate that various measures of effective temperatures generally differ. We discuss infinite hierarchies of effective temperatures defined from moments of the non-exponential energy distribution, and relate them to the "configurational temperature", measured directly from instantaneous particle locations without any kinetic information. We calculate the "granular temperature", characterizing the average energy in the system, two different "fluctuation temperatures", scaling fluctuation-dissipation relations, and the "entropic temperature", defined from differentiating the entropy with respect to energy.

description: Carrollian field theories at the classical level possess an infinite number of space-time symmetries, namely the supertranslations. In this article, we inquire whether these symmetries for interacting Carrollian scalar field theory survive in the presence of quantum effects. For interactions polynomial in the field, the answer is in the affirmative. We also study a renormalization group flow particularly tailored to respect the manifest Carroll invariance and analyze the consequences of introducing Carroll-breaking deformations. The renormalization group flow, with perturbative loop-level effects taken into account, indicates a new fixed point apart from the Gaussian ones.

description: The detection and characterization of partial discharge (PD) are crucial for the insulation diagnosis of overhead lines with covered conductors. With the release of a large dataset containing thousands of naturally obtained high-frequency voltage signals, data-driven analysis of fault-related PD patterns on an unprecedented scale becomes viable. The high diversity of PD patterns and background noise interferences motivates us to design an innovative pulse shape characterization method based on clustering techniques, which can dynamically identify a set of representative PD-related pulses. Capitalizing on those pulses as referential patterns, we construct insightful features and develop a novel machine learning model with a superior detection performance for early-stage covered conductor faults. The presented model outperforms the winning model in a Kaggle competition and provides the state-of-the-art solution to detect real-time disturbances in the field.

description: We describe a scheme that allows for the generation of any desired N-photon state on demand. Under ideal conditions, this requires only N single photon sources, laser pulses and linear optics elements. First, the sources should be initialised with the help of single-qubit rotations and repeat-until-success two-qubit quantum gates [Lim et al., Phys. Rev. Lett. 95, 030305 (2005)]. Afterwards, the state of the sources can be mapped onto the state of N newly generated photons whenever needed.

description: Geleneksel olarak, pnömotorakslı (Px) hastaların uçak yolculuğu yapmaması önerilmektedir. Bu öneriler genellikle spontan Px’lı askerlerin eski deneyimleri sonrasında bir görüş olarak edinilmiştir (1-5). Sonrasında 2003’te Amerika Hava Tıbbı Derneği (Aerospace Medical Association- AsMA) bir klavuz yayınlamıştır ve bu [highlight]klavuza göre pnömotorakslı hastanın uçak yolculuğu yapması kontraendike[/highlight] olarak belirtilmiştir (6). Benzer şekilde İngiliz Toraks Derneği’de (British Thoracic Society - BTS) 2011’de pnömotorakslı hastaların uçağa binmemelerini önermiştir (7). AsMA ‘nın yayınladığı klavuzda travmatik Px (tPx) ta tedavi sonrasında Px görünümü grafiden tamamen kaybolduktan sonra 2-3 hafta boyunca uçak yolculuğu yapmamasını önermektedir. Her iki derneğin görüşlerileri de genel olarak uzman görüşüne dayanmaktadır ve bu kılavuzları destekleyen kuvvetli kanıt yoktur (8). Grafi bulgularının kaybolmasının üzerinden daha 2 hafta geçmeden uçak yolculuğu yapan tPx'li hastaların incelendiği objektif bir çalışma yok (8). tPx'li hastaları, hipobarik ortamda inceleyen göze çarpan sadece bir çalışma bulunmaktadır (Majercik ve ark.) ki o da bu kılavuzların önerdiğinden oldukça farklı bir sonuca ulaşmıştır.

description: Visible light communication (VLC) enables access to huge unlicensed bandwidth, a higher security level, and no radio frequency interference. With these advantages, VLC emerges as a complementary solution to radio frequency communications. VLC systems have primarily been designed for indoor scenarios with typical transmission distances between 2 and 5 m. Different designs would be required for larger distances. This paper proposes for the first time the use of a liquid crystal (LC)-based re-configurable intelligent surface (RIS) on improving the VLC signal detection and transmission range. An LC-based RIS presents multiple advantages, including the tunability of its photo-refractive parameters. Another advantage is its light amplification capabilities when under the influence of an externally applied field. In this paper, we analyze an LC-based RIS structure to amplify the detected light and improve the VLC signal detection and transmission range. Results show that mixing LC with 4 to 8 wt\% concentration of a dye such as the terthiophene (3T-2MB) improves the VLC transmission range of about 0.20 to 1.08 m. This improvement can reach 6.56 m if we combine 8 wt\% concentration of 3T-2MB and 0.1 wt\% concentration of trinitrofluorenone.
