description: Medical Review article in portuguese about Brain Death
ABSTRACT
Brain death represents the irreversible medical condition in which the brain functions (telencephalon and diencephalons) and the brainstem are hopelessly compromised. Three prerequisites are necessary to define it, that is: irreversible coma with known cause; absence of hypothermia, hypotension or severe metabolic disorder; exclusion of exogenous intoxication, or psychotropic drugs effect. It is based on the concomitant presence of coma unresponsive to external stimuli, absence of brain stem reflexes, and the presence of apnea. The diagnosis is established after two clinical tests with an interval of at least six hours, carried out by two different professionals not linked to the transplant team. It is mandatory to prove, through complementary exams, the absence of central nervous system perfusion, or electric activity or metabolism. Brain death means death both legally and scientifically. It is necessary for all health care professionals, especially the physician, to be familiar with the concept of brain death, so that the application of life support technology is beneficial, individually and socially committed, not only to promote inadequate intervention, extension of suffering and familiar distress and futile and artificial prolongation of life

RESUMO
A morte encefálica representa o estado clínico irreversível em que as funções cerebrais (telencéfalo e diencéfalo) e do tronco encefálico estão irremediavelmente comprometidas. São necessários três pré-requisitos para defini-la: coma com causa conhecida e irreversível; ausência de hipotermia, hipotensão ou distúrbio metabólico grave; exclusão de intoxicação exógena ou efeito de medicamentos psicotrópicos. Baseia-se na presença concomitante de coma sem resposta ao estímulo externo, inexistência de reflexos do tronco encefálico e apneia. O diagnóstico é estabelecido após dois exames clínicos, com intervalo de no mínimo seis horas entre eles, realizados por profissionais diferentes e não vinculados à equipe de transplantes. É obrigatória a comprovação, por intermédio de exames complementares, de ausência no sistema nervoso central de perfusão ou atividade elétrica ou metabolismo. Morte encefálica significa morte tanto legal quanto cientificamente. É necessário que todo profissional de saúde, especialmente o médico, esteja familiarizado com o conceito de morte encefálica, para que a aplicação da tecnologia na sustentação da vida seja benéfica, individual e socialmente comprometida, e não apenas promovedora de intervenção inadequada, extensão do sofrimento e angústia familiar e prolongamento inútil e artificial da vida.

description: We review the physics of many-body localization in models with incommensurate potentials. In particular, we consider one-dimensional quasiperiodic models with single-particle mobility edges. Although a conventional perspective suggests that delocalized states act as a thermalizing bath for the localized states in the presence of of interactions, there is evidence that such systems can display non-ergodicity. This is in part due to the fact that the delocalized states do not have any kind of protection due to symmetry or topology and are thus susceptible to localization. A study of non-interacting incommensurate models shows that they admit extended, partially extended, and fully localized many-body states. These models cannot thermalize dynamically and remain localized upon the introduction of interactions. In particular, for a certain range of energy, the system can host a non-ergodic extended (i.e. metallic) phase in which the energy eigenstates violate the eigenstate thermalization hypothesis (ETH) but the entanglement entropy obeys volume-law scaling. The level statistics and entanglement growth also indicate the lack of ergodicity in these models. The phenomenon of localization and non-ergodicity in a system with interactions despite the presence of single-particle delocalized states is closely related to the so-called "many-body proximity effect" and can also be observed in models with disorder coupled to systems with delocalized degrees of freedom. Many-body localization in systems with incommensurate potentials (without single-particle mobility edges) have been realized experimentally, and we show how this can be modified to study the the effects of such mobility edges. Demonstrating the failure of thermalization in the presence of a single-particle mobility edge in the thermodynamic limit would indicate a more robust violation of the ETH.

description: We report K2 observations of the eclipsing cataclysmic variable V729 Sgr which covered nearly 80 days in duration. We find five short outbursts and two long outbursts, one of which shows a clear plateau phase in the rise to maximum brightness. The mean time between successive short outbursts is ~10 d while the time between the two long outbursts is ~38 d. The frequency of these outbursts are unprecedented for a CV above the orbital period gap. We find evidence that the mid-point of the eclipse occurs systematically earlier in outburst than in quiescence. During five of the six quiescent epochs we find evidence for a second photometric period which is roughly 5 percent shorter than the 4.16 h orbital period which we attribute to negative superhumps. V729 Sgr is therefore one of the longest period CVs to show negative superhumps during quiescence.

description: We show that it is possible to achieve information theoretic location privacy for secondary users (SUs) in database-driven cognitive radio networks (CRNs) with an end-to-end delay less than a second, which is significantly better than that of the existing alternatives offering only a computational privacy. This is achieved based on a keen observation that, by the requirement of Federal Communications Commission (FCC), all certified spectrum databases synchronize their records. Hence, the same copy of spectrum database is available through multiple (distinct) providers. We harness the synergy between multi-server private information retrieval (PIR) and database- driven CRN architecture to offer an optimal level of privacy with high efficiency by exploiting this observation. We demonstrated, analytically and experimentally with deployments on actual cloud systems that, our adaptations of multi-server PIR outperform that of the (currently) fastest single-server PIR by a magnitude of times with information theoretic security, collusion resiliency, and fault-tolerance features. Our analysis indicates that multi-server PIR is an ideal cryptographic tool to provide location privacy in database-driven CRNs, in which the requirement of replicated databases is a natural part of the system architecture, and therefore SUs can enjoy all advantages of multi-server PIR without any additional architectural and deployment costs.

Towards Leveraging End-of-Life Tools as an Asset: Value Co-Creation based on Deep Learning in the Machining Industry

Publisher: name: Karlsruhe
Year: 2020

description: Sustainability is the key concept in the management of products that reached their end-of-life. We propose that end-of-life products have—besides their value as recyclable assets—additional value for producer and consumer. We argue this is especially true for the machining industry, where we illustrate an automatic characterization of worn cutting tools to foster value co-creation between tool manufacturer and tool user (customer) in the future. In the work at hand, we present a deep-learning-based computer vision system for the automatic classification of worn tools regarding flank wear and chipping. The resulting Matthews Correlation Coefficient of 0.878 and 0.644 confirms the feasibility of our system based on the VGG-16 network and Gradient Boosting. Based on these first results we derive a research agenda which addresses the need for a more holistic tool characterization by semantic segmentation and assesses the perceived business impact and usability by different user groups.

The Bloch-Beilinson conjectures predict the way $ι$ should act on certain pieces of the Chow groups of $X$. The main result is a verification of this prediction for Fano varieties of lines on certain cubic fourfolds. This has consequences for the Chow ring of the quotient $X/ι$.

description: High resolution electron energy loss spectroscopy (HR-EELS) is utilized to probe the surface spin canting in nanoparticles of two technologically important magnetic materials, i.e. Fe3O4 and CoFe2O4 (CFO). A soft experimental technique is developed that is capable of extracting EELS spectra with one atomic plane resolution recorded in a single frame. This yields information at different depth of the nanoparticle from the surface to the core regions with high signal to noise ratio and without beam damage. This enables comparing the fine structures between the surface and core regions of the nanoparticles. The results confirm earlier observations of uniformly oriented spin canting structure for CFO with additional information on atom site-selective spin canting information. In case of Fe3O4 preferred canting orientation forming core and shell structure is deduced. Unlike earlier reports based on polarized spin-flip neutron scattering measurement, it is possible to narrow down the possible canting angles for Fe3O4 (Td, Oh tilts 40°, 40°) and CFO (Td, Oh tilts 17°, 17°) from the experimental spectra combined with the first principle based calculation considering non-collinear magnetism. In addition, the role of Dzyaloshinskii-Moriya interaction in stabilizing the spin canting at the nanoparticle surface is discussed. The results demonstrate that HREELS can be a powerful technique to probe the magnetic structure in nano-dimensional systems and has advantages over neutron based techniques in terms of superior spatial resolution, site specific information and easy of sample preparation.

description: This short note is a follow-up on the paper by Beig and Chruściel regarding the use of potentials to perform a gluing and shielding of initial data for Maxwell fields and linearised gravity. Based on a work in collaboration with Andersson and Bäckdahl, this gluing and shielding procedure is generalised to higher spin fields. The approach is based on a generalisation of the de Rham complex to higher spin fields providing a parametrization of the set of constraints, as well as standard elliptic theory to prove the existence of a potential for solutions to the constraints for higher spin fields.

description: How can tissues generate large numbers of cells, yet keep the divisional load (the number of divisions along cell lineages) low in order to curtail the accumulation of somatic mutations and reduce the risk of cancer? To answer the question we consider a general model of hierarchically organized self-renewing tissues and show that the lifetime divisional load of such a tissue is independent of the details of the cell differentiation processes, and depends only on two structural and two dynamical parameters. Our results demonstrate that a strict analytical relationship exists between two seemingly disparate characteristics of self-renewing tissues: divisional load and tissue organization. Most remarkably, we find that a sufficient number of progressively slower dividing cell types can be almost as efficient in minimizing the divisional load, as non-renewing tissues. We argue that one of the main functions of tissue-specific stem cells and differentiation hierarchies is the prevention of cancer.

description: What is the maximum overhang that can be obtained when a set of blocks of variable width are stacked so that there is one block at each level? We determine the configuration of blocks that maximises the overhang when these blocks are stacked in a prescribed order. We also describe infinite sets of blocks of variable width that can be stacked to yield towers with arbitrarily large overhang. Additionally, we consider various symmetric configurations of blocks and point masses in the plane. By considering the centres of mass of such configurations we establish various well-known summation formulas, and discover others that are new and appealing.

description: Nonlinear wave interactions affect the evolution of steep wave groups, their breaking and the associated kinematic field. Laboratory experiments are performed to investigate the effect of the underlying focussing mechanism on the shape of the breaking wave and its velocity field. In this regard, it is found that the shape of the wave spectrum plays a substantial role. Broader underlying wave spectra leads to energetic plungers at a relatively low amplitude. For narrower spectra waves break at a higher amplitudes but with a less energetic spiller. Comparison with standard engineering methods commonly used to predict the velocity underneath extreme waves shows that, under certain conditions, the measured velocity profile strongly deviates from engineering predictions.

description: We calculate an electron-phonon scattering and intrinsic transport properties of black phosphorus monolayer using tight-binding and Boltzmann treatments as a function of temperature, carrier density, and electric field. The low-field mobility shows weak dependence on density and, at room temperature, falls in the range of 300 - 1000 cm^2/Vs in the armchair direction and 50 - 120 cm^2/Vs in the zig-zag direction with the anisotropy due to an effective mass difference. At high fields, drift velocity is linear with electric field up to 1 - 2 V/micron reaching values of 10^7 cm/s in the armchair direction, unless self-heating effects are included.

Tensile Strained Gray Tin: a New Dirac Semimetal for Observing Negative Magnetoresistance with Shubnikov-de-Haas Oscillation

Year: 2016
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: The extremely stringent requirement on material quality has hindered the investigation and potential applications of exotic chiral magnetic effect in Dirac semimetals. Here, we propose that gray tin is a perfect candidate for observing the chiral anomaly effect and Shubnikov-de-Haas (SdH) oscillation at relatively low magnetic field. Based on effective $k.p$ analysis and first-principles calculations, we discover that gray tin becomes a Dirac semimetal under tensile uniaxial strain, in contrast to a topological insulator under compressive uniaxial strain as known before. In this newly found Dirac semimetal state, two Dirac points which are tunable by tensile [001] strains, lie in the $k_z$ axis and Fermi arcs appear in the (100) surface. Duo the low carrier concentration and high mobility of gray tin, a large chiral anomaly induced negative magnetoresistance and a strong SdH oscillation are anticipated in this half of strain spectrum. Comparing to other Dirac semimetals, the proposed Dirac semimetal state in the nontoxic elemental gray tin can be more easily manipulated and accurately controlled. We envision that gray tin provides a perfect platform for strain engineering of chiral magnetic effects by sweeping through the strain spectrum from positive to negative and vice versa.
Simultaneous summation and recognition effects for a dual-emitter light-induced neuromorphic device

description: We propose and fabricate a dual-emitter light-induced neuromorphic device composed of two light-induced devices with a common collector and base. Two InGaN multiple quantum well diodes (MQW-diodes) are used as the emitters to generate light, and one InGaN MQW-diode is used as the common collector to absorb the emitted light. When the presynaptic voltages are synchronously applied to the two emitters, the collector demonstrates an adding together of the excitatory post synaptic voltage (EPSV). The width and period of the two input signals constitute the code to generate spatial summation and recognition effects at the same time. Experimental results confirm that temporal summation caused by the repetitive-pulse facilitation could significantly strengthen the spatial summation effect due to the adding together behavior when the repetitive stimulations are applied to the two emitters in rapid succession. Particularly, the resonant summation effect occurs at the co-summation region when the two repetitive-pulse signals have a resonant period, which offers a more sophisticated spatiotemporal EPSV summation function for the dual-emitter neuromorphic device.

Также, наша цель доказать, что в случае с ДНР, помимо несуществующего признания де-юре, есть широкая «серая» сфера возможностей признания де-факто. Статья предлагает изучение исторической аналогии как главного метода изучения этих вопросов.

description: The Josephson supercurrent through the hybrid Majorana--quantum dot--Majorana junction is investigated. We particularly analyze the effect of spin-selective coupling between the Majorana and quantum dot states, which emerges only in the topological phase and will influence the current through bent junctions and/or in the presence of magnetic fields in the quantum dot. We find that the characteristic behaviors of the supercurrent through this system are quite counterintuitive, remarkably differing from the resonant tunneling, e.g., through the similar (normal phase) superconductor--quantum dot--superconductor junction. Our analysis is carried out under the influence of full set-up parameters and for both the $2π$ and $4π$ periodic currents. The present study is expected to be relevant to future exploration of applications of the Majorana-nanowire circuits.

description: В статье рассматриваются вопросы, связанные с историей Азербайджана и Грузии в области военно-политического сотрудничества. В 1801 году после упразднения Картли-Кахетинского царства, а в 1810 году Имеретинского царства, Грузия вплоть до 1917 года на правах Тифлисской и Кутаисской губернии входила в состав Российской империи, а в 1922-1991 годах как союзная республика в состав СССР. Также было и с бывшими азербайджанскими ханствами, которые были насильственно включены в состав Российской империи на правах губерний, а позднее в 1922-1991 годах на правах союзной республики. В 1918-1921-х годах Баку и Тифлис (Тбилиси) были столицами независимых государств Азербайджана и Грузии, зажатыми между Россией и Турцией, региональными державами, соперничавшими за господство на Южном Кавказе, наши страны прошли тяжелейшие годы становления, как самостоятельные государства как в 1918-м году, а также и в тяжелые для республик время устанавливали сотрудничество в военном строительстве и в сфере безопасности.

On the Protective Function off Y-SNPS/Y-STRS, and some Ancient Male Lineages
Creators: name: Smith, John

description: It is generally taken for granted that we inherit about half of our genes from each parent and so that, roughly speaking, a person's similarity to previous generations drops of at the rate 1/2 ^ g, where g is the number of generations separating that person from their ancestors. On this view it doesn't take many generations before the number of unique similarities between someone and their ancestors begins to dwindle to 0. Here this idea is disputed on the basis that non-recombined, rather than recombined DNA, determines identity, and the rate of decay of non-recombined DNA is very slow. It particular, it is suggested that the function of Y-SNPS/Y-STRS is the regulative function of protecting identity over a large number of regenerations.

description: В статье на основании архивных источников анализируются процессы самоорганизации и самоуправления, происходившие в 1917 г. в одном из установлений Министерства императорского двора – Царскосельском дворцовом управлении. Делается вывод о том, что наряду с явлениями, в целом характерными для работы российских выборных организаций революционного времени (бюрократизм, коллегиальное рассмотрение даже самых незначительных вопросов), в общественной деятельности царскосельских дворцовых служащих нашли отражение и специальные, свойственные именно этому коллективу черты. К последним можно отнести аполитичность и наличие монархических чувств, неявно высказываемых даже в самом конце 1917 г.
Kinderarbeit auf Kosten der Kindheit – oder: Wege zu anderer Kindheit?

description: Wenn Kinder ein „Recht zu arbeiten“ für sich beanspruchen, wie es seitens einiger Organisationen von arbeitenden Kindern in Afrika, Asien und Lateinamerika seit Jahren geschieht (vgl. Liebel 2001, S. 33ff.), ruft dies meist Verwunderung und Kopfschütteln hervor. Spätestens seit im Europa des 19. Jahrhunderts Regulative und Gesetze erlassen wurden, in denen die Erwerbsarbeit von Kindern verboten wurde, gehört es zum Grundverständnis westlichen Denkens, dass es das Beste für Kinder sei, nicht zu arbeiten und sich stattdessen der Schule zu widmen.Allerdings gab es auch in Europa immer wieder andere Stimmen. So erschien unter dem provozierenden Titel „Kinderarbeit ist gut“ vor nunmehr 23 Jahren ein Buch zweier norwegischer Pädagogen (Linge/Wille 1984), die das umstrittene Thema von einer ungewohnten Seite angehen. Sie zeigen an konkreten Beispielen, dass die Arbeit von Kindern auch gute Seiten haben und das Leben und Lernen von Kindern bereichern kann. Mit Blick auf ihr Land und die „lebensfernen“ Schulen und Kindergärten, in denen die beiden sich jahrelang abgemüht hatten, forderten sie: „Führt Kinderarbeit wieder ein!“Im folgenden Beitrag gehe ich einigen Kontroversen über die Auswirkungen der Kinderarbeit auf Kinder nach und diskutiere verschiedene Handlungsansätze, die darauf abzielen, die Situation arbeitender Kinder zu verbessern. Mit Blick auf die Forderung Kindern ein Recht zu arbeiten einzuräumen, setze ich mich mit der Befürchtung auseinander, die Kinder würden schutzlos ausbeuterischen Praktiken ausgeliefert und skizziere schließlich einige Gedanken über sich abzeichnende neue Praxisformen von Kindheit und mögliche Konsequenzen für pädagogisches Handeln in der Schule.

description: This letter presents the design, manufacturing and operational performance of a graphene-flakes based screenprinted wideband elliptical dipole antenna operating from 2 GHz up to 5 GHz for low cost wireless communications applications. To investigate radio frequency (RF) conductivity of the printed graphene, a coplanar waveguide (CPW) test structure was designed, fabricated and tested in the frequency range from 1 GHz to 20 GHz. Antenna and CPW were screen-printed on Kapton substrates using a graphene paste formulated with a graphene to binder ratio of 1:2. A combination of thermal treatment and subsequent compression rolling is utilized to further decrease the sheet resistance for printed graphene structures, ultimately reaching 4 Ohm/sq. at 10 μm thicknesses. For the graphene-flakes printed antenna an antenna efficiency of 60% is obtained. The measured maximum antenna gain is 2.3 dBi at 4.8 GHz. Thus the graphene-flakes printed antenna adds a total loss of only 3.1 dB to an RF link when compared to the same structure screen-printed for reference with a commercial silver ink. This shows that the electrical performance of screen-printed graphene flakes, which also does not degrade after repeated bending, is suitable for realizing low-cost wearable RF wireless communication devices.

description: Objectives: The epidemiological transition from infectious to chronic diseases leads to novel challenges in African health systems. The prevalence of diabetes mellitus (DM) is increasing dramatically. Undiagnosed and undertreated DM leads to numerous complications including end-organ damage and death. Our objectives were to collect the best locally generated evidence on DM interventions, identify knowledge gaps and determine underexplored research areas. Design: A systematic review and meta-analysis of randomised controlled trials. Participants and setting: African patients in primary, secondary and tertiary prevention, diagnosis and treatment DM type 1 (DM1), type 2 (DM2) and gestational DM (GDM). Outcome: All-cause mortality, glycaemic control, complications, quality of life, hospital admission, treatment adherence and costs. Data sources: Articles published in MEDLINE Ovid, CENTRAL, CINAHL, African Journals Online and African Index Medicus and the International Clinical Trials Registry Platform in English language without time restrictions. The systematic search was last updated in October 2020. Results: Out of 3736 identified publications, we included 60 eligible studies conducted in 15 countries, 75% were conducted in urban healthcare settings, including 10 112 participants. We included 8 studies on DM1, 6 on GDM, 2 on pre-DM, 37 on mainly DM2 including 7 on DM-related complications. The design of the studied intervention was heterogeneous with a focus on educational strategies. The other studies investigated the efficacy of nutritional strategies including food supplementations, pharmacological strategies and strategies to enhance physical activity. Seven studies included interventions on DM-related complications. Conclusions: Research activities increased in recent years, but available evidence is still not representative for all African countries. There is a big lack of evidence in primary healthcare and rural settings, implementation research, pharmacological interventions, especially in poorer countries. Nevertheless, the identified studies offer a variety of effective interventions that can inform medical care and future research.

description: The long-time photometric surveys in a few young open clusters allowed to identify the light variability in stars located on the HR diagram between the well defined $δ$ Scuti variables and Slowly Pulsating B-type stars. Several objects of this type were suggested also from the analysis of the Kepler data. Assuming the pulsational origin of this variability, we try to explain the observed frequencies with pulsational models involving rotation and/or modification of the mean opacity profile.
