description: It is widely accepted that plasma membrane permeabilization after PEF occurs due to hydrophilic pores formation in the lipid bilayer. The concept of pore formation is confirmed by molecular dynamics (MD) simulations. However, there is increasing evidence that PEF can cause not only hydrophilic pore formation but also modulate membrane proteins and their function, and these changes could be part of increased membrane’s permeability after PEF. Ion channels, especially voltage-gated ion channels, are probable targets of PEF. However, ion channels are an extremely large group, and to identify specific channels responsible for increased conductivity after PEF, high-throughput screening is needed. In this work, we used the lentiviral CRISPR/Cas9 library designed for knockout (KO) of 329 different ion channels or other membrane-associated proteins in the U937/Cas9 cell model. After applying nsPEF (300ns, 7 kV/cm, 20 or 40 pulses at 20 Hz), each KO was screened for YoPro-1 uptake using a custom assembled screening station based on an inverted microscope equipped with automated stage repositioning, IR laser hardware autofocusing (ZDC), and image stitching capabilities. Out of 329 screened KOs, 9 showed lower YO-PRO-1 uptake than control. Such results indicate that proteins coded by these genes either support molecular transport across nsPEF stimulated membrane or proteins could be directly damaged by nsPEF. 20 KOs responded to nsPEF with higher YO-PRO-1 uptake than control, suggesting that these proteins may play the regulatory function of ion channels, or they could be linked to membrane stability and/or repair of the membrane after the electric injury. This is the first high-throughput screening to identify possible nsPEF protein targets in the cell plasma membrane.

description: We study the nearest-neighbor distributions of the $k$-body embedded ensembles of random matrices for $n$ bosons distributed over two-degenerate single-particle states. This ensemble, as a function of $k$, displays a transition from harmonic oscillator behavior ($k=1$) to random matrix type behavior ($k=n$). We show that a large and robust quasi-degeneracy is present for a wide interval of values of $k$ when the ensemble is time-reversal invariant. These quasi-degenerate levels are Shnirelman doublets which appear due to the integrability and time-reversal invariance of the underlying classical systems. We present results related to the frequency in the spectrum of these degenerate levels in terms of $k$, and discuss the statistical properties of the splittings of these doublets.

Optimization of the leak conductance in the squid giant axon

Subjects: subject: Neurons and Cognition (q-bio.NC)

description: We report on a theoretical study showing that the leak conductance density, $\GL$, in the squid giant axon appears to be optimal for the action potential firing frequency. More precisely, the standard assumption that the leak current is composed of chloride ions leads to the result that the experimental value for $\GL$ is very close to the optimal value in the Hodgkin-Huxley model which minimizes the absolute refractory period of the action potential, thereby maximizing the maximum firing frequency under stimulation by sharp, brief input current spikes to one end of the axon. The measured value of $\GL$ also appears to be close to optimal for the frequency of repetitive firing caused by a constant current input to one end of the axon, especially when temperature variations are taken into account. If, by contrast, the leak current is assumed to be composed of separate voltage-independent sodium and potassium currents, then these optimizations are not observed.

description: We present a theory of nonequilibrium quantum criticality in a coupled bilayer system of itinerant electron magnets. The model studied consists of the first layer subjected to an inplane current and open to an external substrate. The second layer is closed and subject to no direct external drive, but couples to the first layer via short-ranged spin exchange interaction. No particle exchange is assumed between the layers. Starting from a microscopic fermionic model, we derive an effective action in terms of two coupled bosonic fields which are related to the magnetization fluctuations of the two layers. When there is no interlayer coupling, the two bosonic modes possess different dynamical critical exponents z with z=2 (z=3) for the first (second) layer. This results in multi-scale quantum criticality in the coupled system. It is shown that the linear coupling between the two fields leads to a low energy fixed point characterized by the larger dynamical critical exponent z=3. The perturbative renormalization group is used to compute the correlation length in the quantum disordered and quantum critical regimes. We also derive the stochastic dynamics obeyed by the critical fluctuations in the quantum critical regime. Comparing the nonequilibrium situation to the thermal equilibrium scenario, where the whole system is at a temperature T, we find that the nonequilibrium drive does not always play the role of temperature.

Nuclear spin relaxation and Overhauser effects in polyatomic gases
Creators: name: Dong, Yi-Yam Ronald
Publisher: name: University of British Columbia
Year: 2011

description: Using modern signal averaging techniques, the proton and fluorine spin-lattice relaxation time T₁ has been measured in CH₄, CF₄, CHF₃, CH₃F, and CF₃Cl gases at low densities and 297°K. By measuring the dependence of T₁ on density near the characteristic T₁ minimum, we have been able to obtain new information on the spin-rotation interaction coupling constants in CF₄, CHF₃, and CH₃F. The CH₄ system was used to test the validity of this method since the spin-rotation coupling constants are accurately known for CH₄. The correlation function for the spin-rotation interaction was found to be exponential within experimental error for all of the molecules studied. The temperature dependence of the fluorine T₁ in CHF₃, CH₃F, and CF₄ was investigated at higher densities. The proton T₁ in CHF₃ and CH₃F have also been studied in the same density region and at several temperatures. A very striking density dependence of the proton T₁ in these two symmetric-top molecules was discovered. A plot of T₁/ρ versus ρ shows "steps". Steady-state Overhauser effects have been studied in experiments performed at 297°K in both CHF₃ and CH₃F gases to demonstrate the importance of the intra-molecular magnetic dipolar interaction at moderate densities. This interaction in CHF₃ and CH₃F is found to be responsible for the peculiar density dependence of the proton T₁. A phenomenological interpretation of the above proton results was given using a high temperature approximation relaxation theory in which the correlations between the spin-dependent interactions of the different nuclei and the existence of three distinct molecular symmetry species in CX₃Y molecules were properly accounted for. A detailed molecular theory for polyatomic molecules is still needed to extract information on the anisotropic part of the inter-molecular potential.

description: The effective potential approach for composite operators has been generalized to non-zero temperatures in order to derive equation of state for the pure SU(3) Yang-Mills fields from first principles. In the absence of external sources it is nothing but the vacuum energy density. The key element of this derivation was an introduction of the temperature dependence into the expression for the Bag constant. Such obtained non-perturbative analytical equation of state for the gluon matter does not depend on the coupling constant, only the dependence on the mass gap, which is responsible for the large-scale structure of the QCD ground state, is present. The important thermodynamic quantities such as the pressure, energy and entropy densities, etc. have been calculated. We have shown explicitly that the pressure may continuously change its regime at $T_c=266.5 Mev$. All other thermodynamic quantities are to be understood to have drastic changes in their regimes at this point. The proposed analytical approach makes it possible to controll thermodynamics of the gluon matter at low temperatures below $T_c$ for the first time. We automatically reproduce the so-called "fuzy"-type bag models properties because of the mass gap explicit presence in our equation of state. We have also analytically calculated the NP gluon condensate as a function of temperature.

В комментарии отмечена важность затронутых в статье методологических вопросов для развития психологической мысли. Показано, что указанные вопросы в ином терминологическом выражении давно поставлены и исследованы возможные на них ответы. Нерешённость базовых теоретико-методологических проблем психологии тормозит её развитие и ограничивает эффективность применения полученных результатов, однако рассматриваемые в комментируемой статье по сути переформулирование указанных проблем и терминологические трансформации их составляющих вряд ли приведут к ожидаемым результатам.
description: The article is a commentary on the Eronen M. and Brinman L. “A theoretical crisis in psychology: how to move forward?” (cur-rent ed., Volume 13). The commentary notes the importance of the methodological issues raised in the article for the development of psychological thought. It is shown that these questions in a different terminological expression have long been posed and the possible answers to them have been investigated. Unresolved basic theoretical and methodological problems of psychology hinder its development and limit the effectiveness of the application of the results obtained, however, the reformulation of these problems and the terminological transformations of their components, considered in the commented article, are unlikely to lead to the expected results

description: Академическая свобода часто защищалась прогрессивным образом: без академической свободы творчество было бы в опасности, а вместе с ним и прогресс знаний, то есть эпистемический прогресс в науке. В этой статье я хочу критически обсудить пределы такой прогрессивной защиты академической свободы, известной также под названием «аргумент от истины». Однако критика предлагается с конструктивной целью, а именно с предложением альтернативы. Эта теория связывает творчество и академическую свободу таким образом, что выходит за рамки простой ссылки на эпистемический прогресс и включает ссылку на свободу мыслить независимо как свободу, которую мы имеем в виду, когда указываем на творчество и на академическую свободу. Полученная теория причинной независимости не только эпистемологически сильнее прогрессистской теории, но также позволяет противостоять ограничению академической свободы во имя прогресса. Последнее становится ключевым, например, когда авторитарные политические режимы ограничивают или отрицают академическую свободу со ссылкой на эпистемический прогресс, надлежащим образом определенный для этого режима.

description: Due to the many anthropogenic as well as natural challenges (oligotrophy,
 heavy human pressure, high rate of biological invasions, exposure to geohazards,
 semi-enclosed sea with a very low turnover time) the Mediterranean
 Sea can be characterized as a diverse but fragile system with low physical
 inertia and limited ecological resilience. Before initiating any type of Blue
 Growth activity or the combinations thereof, the potential ecological impacts
 therefore need to be carefully investigated. Due to the socio-economic and
 cultural diversity of the Mediterranean societies, also social impact studies
 need to be carried out. An adequate balance between benefits and trade-offs
 of innovative Blue Growth activities needs to be carefully planned. In light of
 the geo-political situation the major challenge for the Mediterranean region
 is to create a safer, peaceful and more prosperous region.

description: With recent developments in microscopy, such as stimulated emission depletion (STED) microscopy, far-field imaging at resolutions better than the diffraction limit is now a commercially available technique. Here, we show that, in the special case of a diffusive regime, the noise-limited resolution of STED imaging is independent of the saturation intensity of the fluorescent label. Thermal motion limits the signal integration time, which, for a given excited-state lifetime, limits the total number of photons available for detection.

description: The B²Σ⁺→A²Σ⁺ and C²Σ⁺→A²Σ⁺ systems of OH and OD were photographed at high resolution. The apparent dissociation energy D°(A²Σ⁺) is calculated to be (18847 ± 15) cm⁻¹ for OH and (19263 ± 15) cm⁻¹ for OD. An upper limit to D°(X²π₃/₂) OH is deduced to be (35420 ± 15) cm⁻¹. Evidence for a dispersion hump in the B(²Σ⁺) state which is about 100 cm⁻¹ larger than the hump in the A(²Σ⁺) state is presented. The broadening of the rotational lines in several bands of both systems has established a strong predissociation of the A(²Σ⁺) state near v = 5 in OH. The lifetime of these predissociated levels is ≈10⁻¹¹ seconds. A definite identification of the predissociating state has not been possible. Newly discovered vibrational levels in the C(²Σ⁺) state have led to the following constants, in cm⁻¹, of the OH radical in the C²Σ⁺ state Te = 89500 Be = 4.247 D° = 29418 ± 15 ∝e = 0.078 ωe = 1232.9 Ɣ(v=O) = 1.09 Ωeχe = 19.1 Ɣ(v=1) = 0.88 Rotational constants and spin splitting constants in the A(²Σ⁺) and B(²Σ⁺) states, more accurate than previously available are presented.

description: Abstract

Background: Deaf children experience problems with their hearing organs, resulting in an inability to hear, ranging from mild to very severe levels which are classified into deafness and hard of hearing. A deaf child who is hearing impaired (a deaf person) is a child who is unable to hear, so he experiences obstacles in processing language information through his hearing with or without using a hearing aid. Meanwhile, a child who is hard of hearing (a hard of hearing person) is a deaf child who usually uses a hearing aid, whose remaining hearing is sufficient to enable successful processing of language information, where the child uses a hearing aid, the child can still perceive speech through his hearing. Language ability is an indicator of a child's overall development. Lack of stimulation can cause speech and language disorders and these disorders can even persist. The direct impact of deafness is that verbal communication is hampered, both expressively (speaking) and receptive (understanding other people's speech), making it difficult to communicate with the environment. Barriers to communication result in obstacles in the education and learning process. Assistance for deaf children can be provided at school or at home. Therefore, it is necessary to carry out a Pedagogical Intervention Model for Language Development in deaf children. Research objective: To determine the effect of the Pedagogical Intervention model on Language Development in Deaf Children in Special Schools (SLB) in the Special Region of Yogyakarta. Research Method: Quasi-experimental research with a pretest-posttest with control group design. The research location was at 4 Special Schools in DIY (SLBN Pembina, SLBN II Sewon, SLB Rela Bakti and SLB Karnnamanohara). The population of 90 deaf children was divided into 45 experimental groups and 45 control groups. The sample was 68 deaf children divided into 34 experimental group children and 34 control group children. Using purposive sampling technique. Data analysis used the paired t-test and Wilcoxon test with a significance level of 0.05. Research Results and discussion: Pre-test and post-test language development with a significance result (p value) = 0.00, namely that there is an influence of pedagogical intervention on language development in deaf children in special schools in Yogyakarta Special Region Province Conclusion : There is an influence of Pedagogical Intervention on Language Development in Deaf Children in SLB Special Region of Yogyakarta Province

description: We investigate the discovery potential of cubic kilometer neutrino observatories such as IceCube to set stringent limits on the forbidden decays $η\toν_e\barν_e$ and $η\toν_τ\barν_τ$. The signatures for these decays are cascade events resulting from the charged-current reactions of $ν_e, ν_τ$, $\barν_e$ and $\barν_τ$ on nuclei in such detectors. Background cascade events are mainly due to $ν_e$'s from atmospheric $μ$, $K^+$, and $K^{0}_S$ decays and to a lesser extent from atmospheric $ν_μ$ neutral current interactions with nuclei. A direct upper limit for the branching ratio $η\to ν_{e,τ} \barν_{e,τ}$ of $4.5\times10^{-4}$ at 90% CL can be achieved.

description: Today, software is all around us, impacting our everyday lives in fundamental ways. Developing software whose behaviour is reliable, predictable and correct is therefore crucial. This has made software testing a critical part of the development process and has led to the emergence of rigorous testing practices and standards. Testing any non-trivial system, however, is time-consuming and takes up the bulk of development time. Modern software engineering practices involve the repeated execution of large test suites, as part of regular build, test and release cycles. A common approach to speeding up testing without sacrificing rigour is distributing test executions among computer clusters and cloud servers, but this can be complex and expensive due to the costs of testing infrastructure and energy consumption. This thesis presents a novel approach to accelerating test execution by parallelising it using Graphics Processing Units (GPUs) - powerful and low-cost hardware accelerators that are readily available in the majority of modern desktops. It demonstrates that GPUs can be used to dramatically reduce test execution time at a lower cost compared to other parallel approaches. To achieve this, it addresses significant challenges related to usability, performance and scope, and makes three separate contributions: First, a GPU testing framework, ParTeCL, is developed to automatically transform the system under test into GPU source code and launch test execution in parallel on the GPU threads. ParTeCL performs the entire testing process transparently without requiring any expert GPU programming and architecture knowledge. Second, two types of systems are used to evaluate the applicability and effectiveness of the approach - sequential C programs form the embedded systems domain and Finite State Machine (FSM) models. To enable testing them on the GPU, compiler-based transformations and FSM implementations are developed and included in ParTeCL. Finally, GPU performance is extensively analysed and optimised through a combination of standard and domain specific techniques. Evaluation on programs from the two domains demonstrates that the GPU outperforms a standard 16-core Central Processing Unit (CPU) by up to 4× (avg. 1.4×) for embedded systems and up to 9×(avg. 4.5×) for FSMs. The techniques developed in this thesis demonstrate the exciting possibilities of using specialised hardware architectures, such as GPUs, for the acceleration of software test execution. Through integration into the testing process, they could provide rapid feedback, reducing the amount of costly bug-fixing in later stages of development.

description: I discuss the temperature dependence of quarkonium correlators calculated in lattice QCD. I show that the dominant source of the temperature dependence comes from the zero mode contribution, while the the temperature dependence associated with melting of bound states is quite small. I study the zero mode contribution quantitatively for different quark masses and show that it is well described by a quasi-particle model with temperature dependent heavy quark mass. As a byproduct an estimate of the medium dependence of the heavy quark mass is obtained.

description: In this paper B-Rank, an efficient ranking algorithm for recommender systems, is proposed. B-Rank is based on a random walk model on hypergraphs. Depending on the setup, B-Rank outperforms other state of the art algorithms in terms of precision, recall (19% - 50%), and inter list diversity (20% - 60%). B-Rank captures well the difference between popular and niche objects. The proposed algorithm produces very promising results for sparse and dense voting matrices. Furthermore, a recommendation list update algorithm is introduced,to cope with new votes. This technique significantly reduces computational complexity. The implementation of the algorithm is simple, since B-Rank needs no parameter tuning.

description: Weighted voting games are a family of cooperative games, typically used to model voting situations where a number of agents (players) vote against or for a proposal. In such games, a proposal is accepted if an appropriately weighted sum of the votes exceeds a prespecified threshold. As the influence of a player over the voting outcome is not in general proportional to her assigned weight, various power indices have been proposed to measure each player’s influence. The inverse power index problem is the problem of designing a weighted voting game that achieves a set of target influences according to a predefined power index. In the first part of this thesis, we study the computational complexity of the inverse problem when the power index belongs to the class of semivalues. We prove that the inverse problem is computationally intractable for a broad family of semivalues, including all regular semivalues. As a special case of our general result, we establish computational hardness of the inverse problem for the Banzhaf indices and the Shapley values, arguably the most popular power indices. In the second part, we design efficient approximation algorithms for the inverse semi-value problem. We develop a unified methodology that leads to computationally efficient algorithms that solve the inverse semivalue problem to any desired accuracy. We perform an extensive experimental evaluation of our algorithms on both synthetic and real inputs. Our experiments show that our algorithms are scalable and achieve higher accuracy compared to previous methods in the literature.

description: It is shown that the commonly accepted definition for the Casimir scalar operators of the Poincare group does not satisfy the properties of Casimir invariance when applied to the non-inertial motion of elementary particles while in the presence of external gravitational and electromagnetic fields, where general curvilinear co-ordinates are used to describe the momentum generators within a Fermi normal co-ordinate framework. Specific expressions of the Casimir scalar properties are presented for spin-1/2 to spin-2 particles inclusive. While the Casimir scalar for linear momentum remains a Lorentz invariant in the absence of external fields, this is no longer true for the spin Casimir scalar. Potential implications are considered for the propagation of photons, gravitons, and gravitinos as described by the spin-3/2 Rarita-Schwinger vector-spinor field. In particular, it is shown that non-inertial motion introduces a frame-based effective mass to the spin interaction, with interesting physical consequences that are explored in detail.

description: The presence of a close, low-mass companion is thought to play a substantial and perhaps necessary role in shaping post-Asymptotic Giant Branch and Planetary Nebula outflows. During post-main-sequence evolution, radial expansion of the primary star, accompanied by intense winds, can significantly alter the binary orbit via tidal dissipation and mass loss. To investigate this, we couple stellar evolution models (from the zero-age main-sequence through the end of the post-main sequence) to a tidal evolution code. The binary's fate is determined by the initial masses of the primary and the companion, the initial orbit (taken to be circular), and the Reimers mass-loss parameter. For a range of these parameters, we determine whether the orbit expands due to mass loss or decays due to tidal torques. Where a common envelope (CE) phase ensues, we estimate the final orbital separation based on the energy required to unbind the envelope. These calculations predict period gaps for planetary and brown dwarf companions to white dwarfs. The upper end of the gap is the shortest period at which a CE phase is avoided. The lower end is the longest period at which companions survive their CE phase. For binary systems with 1 $M_\odot$ progenitors, we predict no Jupiter-mass companions with periods $\lesssim$270 days. Once engulfed, Jupiter-mass companions do not survive a CE phase. For binary systems consisting of a 1 $M_\odot$ progenitor with a companion 10 times the mass of Jupiter, we predict a period gap between $\sim$0.1 and $\sim$380 days. These results are consistent with both the detection of a $\sim$50 $M_{\rm J}$ brown dwarf in a $\sim$0.003 AU ($\sim$0.08 day) orbit around the white dwarf WD 0137-349 and the tentative detection of a $\sim$2 $M_{\rm J}$ planet in a $\gtrsim$2.7 AU ($\gtrsim$4 year) orbit around the white dwarf GD66.

description: In this note, we study some properties of the GHZ state. First, we present a quantum secret sharing scheme in which the participants require only classical channels in order to reconstruct the secret; our protocol is significantly more efficient than the trivial usage of teleportation. Second, we show that the classical simulation of an n-party GHZ state requires at least n log n - 2n bits of communication. Finally, we present a problem simpler than the complete simulation of the multi-party GHZ state, that could lead to a no-go theorem for GHZ state simulation.

description: We present an infinite series formula based on the Karoubi-Hamida integral, for the universal Borel class evaluated on H_{2n+1}(GL(\mathbb{C})). For a cyclotomic field F we define a canonical set of elements in K_3(F) and present a novel approach (based on a free differential calculus) to constructing them. Indeed, we are able to explicitly construct their images in H_{3}(GL(\mathbb{C})) under the Hurewicz map. Applying our formula to these images yields a value V_1(F), which coincides with the Borel regulator R_1(F) when our set is a basis of K_3(F) modulo torsion. For F= \mathbb{Q}(e^{2πi/3}) a computation of V_1(F) has been made based on our techniques.

description: Abstract

The development of pop-up advertisements has been one of the most significant changes to the online advertising landscape in recent years. Pop-up advertisements, which were once despised for being obtrusive and disruptive, have evolved to satisfy both users and advertisers. In this article, we examine the intriguing history of pop-up advertisements, including their early years, the advent of ad-blockers, the adoption of targeted advertising and personalization strategies, the emergence of native advertising, and the shift towards interactive and engaging pop-ups. We also explore the moral issues raised by these advertisements and talk about the developments and trends that will influence them in the future.
