description: While ResearchGate has become the most popular academic social networking site in terms of regular users, not all institutions have joined and the scores it assigns to academics and institutions are controversial. This paper assesses the presence in ResearchGate of higher education institutions in Europe and the US in 2017, and the extent to which institutional ResearchGate Scores reflect institutional academic impact. Most of the 2258 European and 4355 US higher educational institutions included in the sample had an institutional ResearchGate profile, with near universal coverage for PhD-awarding institutions found in the Web of Science (WoS). For non-PhD awarding institutions that did not publish, size (number of staff members) was most associated with presence in ResearchGate. For PhD-awarding institutions in WoS, presence in RG was strongly related to the number of WoS publications. In conclusion, a) institutional RG scores reflect research volume more than visibility and b) this indicator is highly correlated to the number of WoS publications. Hence, the value of RG Scores for institutional comparisons is limited.

description: Hintergrund: Zu Therapieabbrüchen in der ambulanten Verhaltenstherapie und damit verbundenen Risikofaktoren existieren bisher nur wenige und gemischte Ergebnisse. In dieser Studie wurden Risikofaktoren für Therapieabbrüche erfasst und untersucht, ob sich ein riskanter Alkoholkonsum (bei Therapiebeginn) auf die Therapieabbrüche in einer verhaltenstherapeutischen Hochschulambulanz auswirkt. Patienten und Methoden: 178 Patienten wurden unterteilt in a) Completer (reguläre Beendigung der Psychotherapie) und b) Dropouts (vorzeitiger Abbruch). Als Risikofaktoren wurden soziodemografische und klinische Variablen untersucht (z.B. Brief-Symptom-Inventar, Beck-Depressions-Inventar, Alcohol Use Disorders Identification Test (AUDIT) usw.). Ergebnisse: 93 Patienten (52%) schlossen die Psychotherapie regulär ab (Completer), 85 (48%) brachen vorzeitig ab (Dropouts; davon 45 in Probatorik und 40 danach). Die Dropouts waren bei Therapiebeginn älter als die Completer (M = 35,33 vs. M = 29.08 Jahre; p = 0,001), waren häufiger beschäftigt (64 vs. 45%; p = 0,014), hatten häufiger komorbide Diagnosen (55 vs. 34%; p = 0,005), waren stärker psychisch belastet (Global Severity Index: M = 1,25 vs. 1,01; p = 0,007) und wiesen einen riskanteren Alkoholkonsum auf (AUDIT: M = 10,49 vs. M = 5,01; p ≤ 0,001). Das Alkoholkonsum-Verhalten bei Therapiebeginn prädizierte einen vorzeitigen Therapieabbruch (b = 0,11; p = 0,001). Ein riskantes Alkoholkonsum-Verhalten war mit einem Dropout in der Probatorik assoziiert (p = 0,005). Schlussfolgerungen: Ein riskanter Alkoholkonsum ist bei ambulanten Psychotherapiepatienten mit vorzeitigem Therapieabbruch korreliert. Komorbides riskantes Trinkverhalten sollte zu Beginn der ambulanten Psychotherapie erfasst und inhaltlich thematisiert werden.

description: The real and imaginary part of the quartet S wave phase shift in nd scattering (^4 S_{3/2}) for centre-of-mass momenta of up to 300 MeV (E_cm \approx 70 MeV) is presented in effective field theory, using both perturbative pions and a theory in which pions are integrated out. As available, the calculation agrees with both experimental data and potential model calculations, but extends to a higher, so far untested momentum régime above the deuteron breakup point. A Lagrangean more feasible for numerical computations is derived.

Some New Results on Yang-Lee Zeros of the Ising Model Partition Function

description: We prove that for the Ising model on a lattice of dimensionality $d \ge 2$, the zeros of the partition function $Z$ in the complex $μ$ plane (where $μ=e^{-2βH}$) lie on the unit circle $|μ|=1$ for a wider range of $K_{n n'}=βJ_{nn'}$ than the range $K_{n n'} \ge 0$ assumed in the premise of the Yang-Lee circle theorem. This range includes complex temperatures, and we show that it is lattice-dependent. Our results thus complement the Yang-Lee theorem, which applies for any $d$ and any lattice if $J_{nn'} \ge 0$. For the case of uniform couplings $K_{nn'}=K$, we show that these zeros lie on the unit circle $|μ|=1$ not just for the Yang-Lee range $0 \le u \le 1$, but also for (i) $-u_{c,sq} \le u \le 0$ on the square lattice, and (ii) $-u_{c,t} \le u \le 0$ on the triangular lattice, where $u=z^2=e^{-4K}$, $u_{c,sq}=3-2^{3/2}$, and $u_{c,t}=1/3$. For the honeycomb, $3 \cdot 12^2$, and $4 \cdot 8^2$ lattices we prove an exact symmetry of the reduced partition functions, $Z_r(z,-μ)=Z_r(-z,μ)$. This proves that the zeros of $Z$ for these lattices lie on $|μ|=1$ for $-1 \le z \le 0$ as well as the Yang-Lee range $0 \le z \le 1$. Finally, we report some new results on the patterns of zeros for values of $u$ or $z$ outside these ranges.

description: If you look carefully, then observed now natural polymorphism does not come down to the simplest neo-Darwinist constructions, but one way or another involves, as a provoking factor, the so-called "outside interference". Nevertheless, the indisputable fundamental role of the evolutionary principle is all the same visible literally at every step. This is both rather intricate genesis of prions, and microevolutionary shifts which, by the way, are taking place before our eyes (invasions of previously unseen mosquitoes and rats, the formation of new strains of bacteria resistant to various poisons, target introduction of valuable cultivars and breeds); just like the racial differences of people that, apparently, have been the best explained by J.-P. Lamarck who, alas, was then outcasted with almost the entire scientific world.

Therefore, the natural progress is first of all, while creationism can, in general, be considered only as one of its tactical moves.

description: We first review traditional approaches to memory storage and formation, drawing on the literature of quantitative neuroscience as well as statistical physics. These have generally focused on the fast dynamics of neurons; however, there is now an increasing emphasis on the slow dynamics of synapses, whose weight changes are held to be responsible for memory storage. An important first step in this direction was taken in the context of Fusi's cascade model, where complex synaptic architectures were invoked, in particular, to store long-term memories. No explicit synaptic dynamics were, however, invoked in that work. These were recently incorporated theoretically using the techniques used in agent-based modelling, and subsequently, models of competing and cooperating synapses were formulated. It was found that the key to the storage of long-term memories lay in the competitive dynamics of synapses. In this review, we focus on models of synaptic competition and cooperation, and look at the outstanding challenges that remain.

description: There is a wide range of science and applications accessible via the strain engineering of quantum transport in 2D materials. We propose a realistic experimental platform for uniaxial strain engineering of ballistic charge transport in graphene. We then develop an applied theoretical model, based on this platform, to calculate charge conductivity and demonstrate graphene quantum strain transistors (GQSTs). We define GQSTs as mechanically strained ballistic graphene transistors with on/off conductivity ratios $> 10^{4}$, and which can be operated via modest gate voltages. Such devices would permit excellent transistor operations in pristine graphene, where there is no band gap. We consider all dominant uniaxial strain effects on conductivity, while including experimental considerations to guide the realization of the proposal. We predict multiple strain-tunable transport signatures, and demonstrate that a broad range of realistic device parameters lead to robust GQSTs. These devices could find applications in flexible electronic transistors, strain sensors, and valleytronics.
Canonical Transformations and Gauge Fixing in the Triplectic Quantization

description: We show that the generators of canonical transformations in the triplectic manifold must satisfy constraints that have no parallel in the usual field antifield quantization. A general form for these transformations is presented. Then we consider gauge fixing by means of canonical transformations in this Sp(2) covariant scheme, finding a relation between generators and gauge fixing functions. The existence of a wide class of solutions to this relation nicely reflects the large freedom of the gauge fixing process in the triplectic quantization. Some solutions for the generators are discussed. Our results are then illustrated by the example of Yang Mills theory.

description: Modifying the position and numbers of lateral fluorine substituent is a common method to design and adjust the mesophase of liquid crystal compounds. Here, a series of 2-(2,2ʹ-difluoro-4ʹ-alkoxy-1,1ʹ-biphenyl-4-yl)-5-substituted benzoxazole with both non-polar (H, CH3) and polar (NO2) groups (coded as nPF(2)PF(2)Bx) is synthesised and characterised. All of the compounds show a conspicuous inter-ring twist angle of 38° compared with corresponding reference compounds I and II which are calculated by density functional theory method, and it is interesting to note that the final compounds nPF(2)PF(2)Bx show only nematic mesophase during heating or cooling. Meanwhile, the UV-vis absorption bands and photoluminescence emission peaks both display remarkable blue-shifted. The aforementioned results reveal that lateral difluoro substituents play a key role to stable the nematic mesophase by increasing the dihedral angle of biphenyl.

description: A phenomenological ansatz for the flavor-asymmetry of the light sea distributions of the nucleon, based on the Pauli exclusion principle, is proposed. This ansatz is compatible with the measured flavor-asymmetry of the unpolarized sea distributions, $\bar{d}>\bar{u}$, of the nucleon. A prediction for the corresponding polarized flavor-asymmetry is presented and shown to agree with predictions of (chiral quark--soliton) models which successfully reproduced the flavor-asymmetry of the unpolarized sea.

Risk and Uncertainty

description: Risk and the presence or absence of risk reduction mechanisms at the village and regional level condition opportunities for policy reform. A question, somewhat prior to the policy reform question, is thus clearly posed: how good or how bad are the existing institutions. In villages in southern India important risks are erratic rainfall, crop and human diseases, and severe income fluctuations. Previous research, by studying only one market or institution, may have neglected smoothing possibilities between markets or institutions. A general equilibrium framework is developed to overcome this problem, assessing risk-sharing markets or institutions in a more unified context. Using household data from three villages in southern India, a significant comovement in consumptions suggest that local financial markets there are good, if not perfect, but several anomalies exist, including the low impact of income on consumption and the effect of time varying characteristics such as land holdings on consumption. An explicit private information model could be consistent with the extent of comovement in consumptions while delivering some of these anomalies.

description: Pheidole nasutoides Holldobler and Wilson
Pheidole nasutoides Holldobler and Wilson 1992: 16. Types Mus. Comp. Zool. Harvard.
Etymology Compound Greek and Latin ("like nasute"), referring to resemblance of the major to a Nasutitermes soldier.
Diagnosis A medium-sized member of the flavens group, whose major possesses 2 teeth (as opposed to the usual 4 or 5) on the hypostoma; uniquely bicolorous head (see below); promesonotum perfectly semicircular in side view and subangular in dorsal-oblique view. Also, the minor is unusual in its narrow occiput with nuchal collar.
Similar to defecta of Guatemala (known only from the major caste and placed tentatively in the pilifera group), differing in the shape of promesonotal and propodeal spine, sculpturing, and color.
Measurements (mm) Holotype major: HW 0.80, HL 0.78, SL 0.50, EL 0.12, PW 0.34. Paratype minor: HW 0.48, HL 0.54, SL 0.54, EL 0.10, PW 0.32.
Color Major: color medium yellow, except for a light brown "mask" as depicted in the figure; the intensity and shape of the mask varies considerably among the major workers in the type series. Minor: concolorous medium yellow.
Range Known only from the type series. Repeated attempts by Holldobler and Wilson (see 1992) and J. T. Longino (1997) to discover additional colonies at and around the type locality have been unsuccessful, suggesting that the species is either very rare or a relatively inaccessible canopy dweller.
biology The type colony was found in a round mass of dried, thatch-like vegetation about 1.5 meters from the ground in the moderately dense foliage of a small tree at the border of open experimental fields of the La Selva Biological Station. When the nest was disturbed, more than a hundred major and minor workers rushed out and ran in erratic looping patterns to form a spreading wave away from the nest. The resemblance of the majors to NasutUermes nasute soldiers similarly provoked was remarkable. In particular, the mask of the P. nasutoides majors is roughly shaped like the head of the nasute termites and contrasts with the light remainder of the body in the same way (Holldobler and Wilson 1992).

description: Policy Reforms in developing countries have been hindered by the lack of appropriate institutional structures. An application of "The New Institutional Economics" is an analysis of these institutional structures. This research extends and refines the apparatus out of which "The New Institutional Economics" works, in order to make it more responsive to four reported problems and critiques: (1) research into the institutional environment (emphasizing institutional rules such as customs, laws and politics) and research into institutions of governance (focusing on the comparative efficacy of alternative generic forms of governance) has developed in disjunct ways; (2) transaction cost economics deals with polar forms such as markets or hierarchies, to the neglect of intermediate or hybrid forms (long-term contracting, reciprocal trading, regulation and franchising); (3) applications have emphasized measuring transactions to the exclusion of measuring governance; and (4) transactions cost economics have not been applied to non-Western and non-capitalist economies. •

description: We construct an equation-of-state for nuclear matter based on the chiral Lagrangian. The relevant scales are discussed and an effective chiral power expansion scheme, which is constructed to work around the nuclear saturation density, is presented. A realistic equation-of-state is obtained by adjusting one free parameter, when the leading and subleading terms in the expansion are included. The saturation mechanism is due to correlations induced by the one-pion-exchange interaction. Furthermore, we find a substantial deviation from the Fermi-gas estimate of the quark condensate in nuclear matter already at the saturation density.

description: Binary stars constitute a large percentage of the stellar population, yet relatively little is known about the planetary systems orbiting them. Most constraints on circumbinary planets (CBPs) so far come from transit observations with the Kepler telescope, which is sensitive to close-in exoplanets but does not constrain planets on wider orbits. However, with continuous developments in high-contrast imaging techniques, this population can now be addressed through direct imaging. We present the full survey results of the Search for Planets Orbiting Two Stars (SPOTS) survey, which is the first direct imaging survey targeting CBPs. The SPOTS observational program comprises 62 tight binaries that are young and nearby, and thus suitable for direct imaging studies, with VLT/NaCo and VLT/SPHERE. Results from SPOTS include the resolved circumbinary disk around AK Sco, the discovery of a low-mass stellar companion in a triple packed system, the relative astrometry of up to 9 resolved binaries, and possible indications of non-background planetary-mass candidates around HIP 77911. We did not find any CBP within 300 AU, which implies a frequency upper limit on CBPs (1--15 $M_{\rm Jup}$) of 6--10 % between 30-300 AU. Coupling these observations with an archival dataset for a total of 163 stellar pairs, we find a best-fit CBP frequency of 1.9 % (2--15 $M_{\rm Jup}$) between 1--300 AU with a 10.5 % upper limit at a 95 % confidence level. This result is consistent with the distribution of companions around single stars.

description: This paper investigates structural wage reform pertaining to medium and large state-owned enterprises, within the context of the 1988 Enterprise Law. Evidence exists that this reform package failed to achieve its full potential. A primary purpose of the paper is to analyze this • failure with the aid of principal-agent analysis, in which the manager is the principal and the workers are the agents. The analysis suggests that the reforms performed poorly since the workers' incentive problem was not adequately addressed. Much of the bonuses became fixed wage supplements, not tied to the output or profit of the enterprise. Moreover, freeriding incentives among workers were not adequately addressed. Multilevel concerns and the • formation of coalitions among workers and supervisors are also analyzed. Means for making the reforms more effective are suggested. For example, rule governance can dilute collusion.

description: Multimedia technologies play a key role in the educational process, particularly in shaping metacognitive skills in Alpha generation children. Children born after 2010, known as Alpha generation, face a world saturated with digital technologies that significantly influence their cognitive and metacognitive development. This article analyzes Kazakh and international studies aimed at identifying the relationship between the use of multimedia technologies and the development of skills such as self-regulation, reflection, and planning. Examples of the application of interactive educational platforms, adaptive programs, and mobile applications are examined, along with the role of teacher training in the effective integration of these technologies into the educational process. Additionally, the importance of creating a supportive educational environment where multimedia tools can be used to promote active learning is emphasized. It is highlighted that the use of technologies not only contributes to a deeper understanding of the material but also fosters critical thinking in children, which is essential in today’s innovation-driven and ever-changing world.

description: We have investigated the threshold of photodetachment of Li^- leading to the formation of the residual Li atom in the $2p ^2P$ state. The excited residual atom was selectively photoionized via an intermediate Rydberg state and the resulting Li^+ ion was detected. A collinear laser-ion beam geometry enabled both high resolution and sensitivity to be attained. We have demonstrated the potential of this state selective photodetachment spectroscopic method by improving the accuracy of Li electron affinity measurements an order of magnitude. From a fit to the Wigner law in the threshold region, we obtained a Li electron affinity of 0.618 049(20) eV.

description: Botnets in online social networks are increasingly often affecting the regular flow of discussion, attacking regular users and their posts, spamming them with irrelevant or offensive content, and even manipulating the popularity of messages and accounts. Researchers and cybercriminals are involved in an arms race, and new and updated botnets designed to defeat current detection systems are constantly developed, rendering such detection systems obsolete. In this paper, we motivate the need for a generalized evaluation in Twitter bot detection and propose a methodology to evaluate bot classifiers by testing them on unseen bot classes. We show that this methodology is empirically robust, using bot classes of varying sizes and characteristics and reaching similar results, and argue that methods trained and tested on single bot classes or datasets might not able to generalize to new bot classes. We train one such classifier on over 200,000 data points and show that it achieves over 97% accuracy. The data used to train and test this classifier includes some of the largest and most varied collections of bots used in literature. We then test this theoretically sound classifier using our methodology, highlighting that it does not generalize well to unseen bot classes. Finally, we discuss the implications of our results, and reasons why some bot classes are easier and faster to detect than others.

description: This paper proposes a novel vibration energy harvesting strategy based on an extension of the Synchronous Electric Charge Extraction (SECE) approach, enabling both the maximization of the harvested power and a consequent bandwidth enlargement in the case of highly coupled/lightly damped piezoelectric energy harvesters. The proposed strategy relies on the tuning of the frequency of the energy extraction events, which is either N times greater than the vibration frequency (Multiple SECE case, N > 1) or 1/N times smaller (Regenerative SECE, N < 1). We first prove analytically than increasing or decreasing N both lead to a damping reduction. While N has no impact on the system's resonance frequency in the Regenerative case (N < 1), we show that this resonant frequency becomes a function of N in the Multiple SECE case (N > 1). Experimental results on a highly coupled/lowly damped piezoelectric harvester (k^2= 0.44, Q_m = 20) demonstrates the potential of this strategy, leading to 257% harvested power improvement compared to SECE (N = 1). and the possibility to tune the resonant frequency on a range as large as 35% of the short-circuit resonant frequency of the harvester.

description: We determine the low energy description of N=2 supersymmetric SU(k) product group theories with bifundamental and fundamental matter based on M-theory fivebrane configurations. The dependence on moduli and scales of the coefficients in the non-hyperelliptic Seiberg-Witten curves for these theories is determined by considering various field theory and brane limits. A peculiarity in the interpretation of these curves for the vanishing beta-function case is noted.

description: In inertial confinement fusion, the scientific issues include the generation and transport of driver energy, the pellet design, the uniform target implosion physics, the realistic nuclear fusion reactor design, etc. In this paper, we present a pellet injection into a power reactor in heavy ion inertial fusion. We employ a magnetic correction method to reduce the pellet alignment error in heavy ion inertial fusion reactor chamber, including the gravity, the reactor gas drag force and the injection errors. We found that the magnetic correction device proposed in this paper is effective to construct a robust pellet injection system with a sufficiently small pellet alignment error.

description: A map on finitely many fermionic modes represents a unitary evolution if and only if it preserves canonical anti-commutation relations. We use this condition for the classification of fermionic cellu- lar automata (FCA) on Cayley graphs of finite groups in two simple but paradigmatic case studies. The physical properties of the solutions are discussed. Finally, features of the solutions that can be extended to the case of cellular automata on infinite graphs are analyzed.

description: Background: Recrystallization of drug and incomplete drug release from liquisolid formulation are two major hurdles in the development of a supersaturated self-nanoemulsifying drug delivery system. The aim of this research work was to develop a solid supersaturated self-nanoemulsifying drug delivery system of fenofibrate (FB) for enhanced dissolution. Methods: FB loaded supersaturated self-nanoemulsifying preconcentrate (superSNEP) was prepared using dimethyl acetamide (DMA), medium chain triglycerides (MCT), and kolliphor EL. Co-processed excipients (CPE) prepared using inorganic microporous silica (Neusilin US2, Florite 100, or Aerosil 200) and hydrophilic polymers (Polyvinyl alcohol, HPMC, and Kollidon VA64) were evaluated for flow property, BET surface area, and adsorption capacity. Lipophilic fluorescent probe (coumarin-6) was used to investigate the extent of self-emulsification. The formulation was further characterized for solid state, in-vitro cytotoxicity in caco-2 cell line and in-vitro dissolution in a sink and non-sink conditions. Results: Optimized superSNEP with 20% w/v FB loading spontaneously formed nanoglobules of 40 ± 2.7 nm. DMA based self-nanoemulsifying system was found to be nontoxic to Caco-2 cell even at a very high concentration. CPE prepared using PVA and Florite 100 (1:1 weight ratio) showed the highest adsorption capacity (1 mL/g) and complete release of oil as depicted by fluorescence study. DSC thermogram and PXRD of S-superSNEP confirmed that FB remained in a solubilized state. S-superSNEP showed significantly faster and higher dissolution of FB in sink and non-sink conditions compared to the plain API. Conclusion: DMA and PVA-F100 based novel co-processed excipient could be potentially useful for the development of solid supersaturated self-nanoemulsifying drug delivery system for enhancing dissolution of lipophilic drugs.

description: We employ a bispinor gap equation to study superfluidity at nonzero chemical potential: mu .neq. 0, in two- and three-colour QCD. The two-colour theory, QC2D, is an excellent exemplar: the order of truncation of the quark-quark scattering kernel: K, has no qualitative impact, which allows a straightforward elucidation of the effects of mu when the coupling is strong. In rainbow-ladder truncation, diquark bound states appear in the spectrum of the three-colour theory, a defect that is eliminated by an improvement of K. The corrected gap equation describes a superfluid phase that is semi-quantitatively similar to that obtained using the rainbow truncation. A model study suggests that the width of the superfluid gap and the transition point in QC2D provide reliable quantitative estimates of those quantities in QCD.
