description: Warm dense matter (WDM) -- an exotic state of highly compressed matter -- has attracted high interest in recent years in astrophysics and for dense laboratory systems. At the same time, this state is extremely difficult to treat theoretically. This is due to the simultaneous appearance of quantum degeneracy, Coulomb correlations and thermal effects, as well as the overlap of plasma and condensed phases. Recent breakthroughs are due to the successful application of density functional theory (DFT) methods which, however, often lack the necessary accuracy and predictive capability for WDM applications. The situation has changed with the availability of the first \textit{ab initio} data for the exchange-correlation free energy of the warm dense uniform electron gas (UEG) that were obtained by quantum Monte Carlo (QMC) simulations, for recent reviews, see Dornheim \textit{et al.}, Phys. Plasmas \textbf{24}, 056303 (2017) and Phys. Rep. \textbf{744}, 1-86 (2018). In the present article we review recent further progress in QMC simulations of the warm dense UEG: namely, \textit{ab initio} results for the static local field correction $G(q)$ and for the dynamic structure factor $S(q,ω)$. These data are of key relevance for the comparison with x-ray scattering experiments at free electron laser facilities and for the improvement of theoretical models. In the second part of this paper we discuss simulations of WDM out of equilibrium. The theoretical approaches include Born-Oppenheimer molecular dynamics, quantum kinetic theory, time-dependent DFT and hydrodynamics. Here we analyze strengths and limitations of these methods and argue that progress in WDM simulations will require a suitable combination of all methods. A particular role might be played by quantum hydrodynamics, and we concentrate on problems, recent progress, and possible improvements of this method.

description: The low-energy limits of the string theory lead to the higher-order curvature corrections for Einstein gravity. Also, they give the higher-order derivative corrections for the Maxwell or linear electrodynamics, which suggests the nonlinear electrodynamics. Inspired by this, in this paper we investigate $d$-dimensional holographic superconductors in the probe limit in the framework of Einstein-Gauss-Bonnet gravity and exponential nonlinear electrodynamics. Based on the Sturm-Liouville eigenvalue method, we compute the critical temperature, the condensation value, and the critical exponent. It is observed that the critical temperature decreases when the Gauss-Bonnet (GB) parameter or the nonlinear parameter increases, but it increases with the higher dimension of the spacetime at the efficiently low charge density. In addition, we found that the condensation value becomes larger as increasing the GB parameter, the nonlinear parameter as well as the spacetime dimension. Finally, we calculate the optical conductivity and study the effects of the GB term and exponential nonlinear electrodynamics on superconducting energy gap.

description: The economic transition and market globalization processes have triggered structural changes in the Macedonian agriculture and influence on the efficiency and competitiveness in the pig production sub-sector. This paper aims to identify the level of technical efficiency on pig farms in the Republic of Macedonia. The Data Envelopment Analysis approach is used to measure the efficiency level, taking into consideration the exact quantity of inputs used in the production in relation to a given quantity of output. The data is analysed by making comparative analyses of the managerial behaviour and other non-measurable variables that influence the efficiency. The results determine what managerial activities influence the efficiency. They indicate the type and level of inputs that need to be changed, so that farms could reach the same technical efficiency achieved by the best farmers.......Procesi ekonomske tranzicije i tržišne globalizacije potaknuli su promjene u makedonskoj poljoprivredi i izvršili utjecaj na učinkovitost i konkurentnost u svinjogojskom podsektoru. Cilj ovoga rada je određivanje razine tehničke učinkovitosti na svinjogojskim farmama u Republici Makedoniji. Korištena je metoda analize omeđivanja podataka kako bi se izmjerila razina učinkovitosti, pri čemu se uzela u obzir točna količina inputa u proizvodnju u odnosu na dobivenu količinu outputa. Podaci su analizirani pomoću komparativne analize menadžerskog ponašanja i ostalih nemjerljivih varijabli koje utječu na učinkovitost. Oni ukazuju na to da se vrsta i razina inputa moraju promijeniti na farmama, kako bi se dosegla razina učinkovitosti koji postižu najbolji poljoprivrednici.

description: We present some analytic results for the steady states of the Penna model of sen escence, generalised to allow genetically identical individuals to die at differ ent ages via an arbitrary survival function. Modelling this with a Fermi functio n (of modest width) we obtain a clear mortality plateau late in life: something that has so far eluded explanation within such mutation accumulation models. This suggests that factors causing variable mortality withi n genetically identical subpopulations, which include environmental effects, may be essential to understanding the mortality plateau seen in many real species.

description: After the political, economic and social transformation in 1989-1990, the farm structure in Hungary became undoubtedly more diverse than earlier. The new farm structure is radically different from the characteristics of its main competitors, mainly of other EU member states. The past two decades after the transition was a period long enough to appreciate the characteristics and the main changes in the farm structure, so the current relevance of this topic is unquestionable. Viability, subsistence and competitiveness are significant concepts which could be measured by the profitability of the agricultural holdings. It is very important to define the main criteria of viability, subsistence and competitiveness but we should not forget the multifunctional role of agriculture as this could solve very important challenges, especially in maintaining the rural population and helping their livelihoods.....Nakon političkih, ekonomskih i društvenih promjena od 1989.-1990. struktura farmi se u Mađarskoj bez sumnje značajno promijenila u odnosu na prethodno razdoblje. Nova struktura farme bitno se razlikuje po svojim obilježjima od strukture farme glavnih konkurenata, uglavnom ostalih zemalja članica EU. Protekla dva desetljeća nakon tranzicije trebala su biti dovoljna da se procijene karakteristike i glavne promjene u strukturi farme, tako da je trenutna važnost teme neupitna. Održivost, opstanak i konkurentost predstavljaju važan koncept koji bi se mogao mjeriti profitabilnošću poljoprivrednih posjeda. Vrlo je bitno odrediti glavne kriterije održivosti, opstanka i konkurentosti, no ne smijemo smetnuti s uma multifunkcionalnu ulogu poljoprivrede, budući da ona može riješti važne izazove, posebice u zadržavanju ruralne populacije i pomoći njihovim domaćinstvima.

 Distribution
 Previously recorded (see Monniot and Monniot 1984; Kott 1985; Nishikawa 1991): Western Australia (Dampier Archipelago, Cape Jaubert, NW Cape, Port Hedland, Carnarvon, Shark Bay, Cockburn Sound, Albany); South Australia (Spencer Gulf); Victoria (Bass Strait); New South Wales (Port Hacking, Long Reef); Queensland (Moreton Bay, Capricorn Group, Low Isles); Northern Territory (Darwin); Palau Is, Philippines, Noumea, New Caledonia, Marianas Is, Japan, Fiji, South China Sea, Japan, Sri Lanka. New record: Queensland (18.845 ° S, 146.795 ° E, 26 m)
 Remarks
 Monniot and Monniot (1984) examined material from Heller’s type locality, Sri Lanka, and found it agreed with the type specimen of Styela areolata Heller, 1878, in having a deeply curved gut loop and about 12 openings of the short vas deferens on the surface of the ovary. Nishikawa (1991) found three to four similar openings in some from Japan but never as many as the Sri Lanka specimens. As a consequence, these authors proposed that C. irene (Hartmeyer, 1906) from Japan (with C. valborgi Hartmeyer, 1919 and C. irma Hartmeyer, 1927 from northwestern Australia as junior synonyms) was distinct from C. areolata Heller, 1878 from Sri Lanka. Specimens assigned to this species by Kott (1985) from Australian locations (Heron Is, Cockburn Sound, South Australia) have been reexamined together with specimens from Fiji and the South China Sea (see Kott 1981; Kott and Goodbody 1982). In all the specimens examined the general morphology is similar, the vas deferens of each gonad opens by a single simple opening on top of the oviducal opening and multiple openings were not detected.
Nevertheless in view of Nishikawa’s (1991) reports of openings of the male duct similar to those in the Sri Lanka specimen, albeit not so numerous, it appears that the openings of the male duct are sometimes subdivided in this species. At this stage, it appears that such subdivision may be the result of intra-specific variation rather than an indication of speciation.

description: Impairments in decision-making have been reported in brain-damaged (stroke/traumatic brain injury) patients with a wide range of lesion sites. Here, we propose that the performances of patients in complex sequential decision-making (DM) tasks can be explained by their negative affectivity, leading to deliberative processing associated with poor DM performances. We assumed that a slow-paced breathing (SPB) training, by reducing negative affectivity would improve performances in a complex DM task. For 24 days, 34 brain-damaged patients (16 males and 18 females; 12 had a hemorrhagic stroke, 17 with an ischemic stroke and 5 with a TBI), practiced either daily SPB or sham trainings for five min, three times a day. Before and after training, we assessed their vagal tone (electrocardiogram—ECG), affectivity (Positive and Negative Affect Schedule—PANAS) and certainty level (Dimensional Ratings Questionnaire—DRQ) and their performance on the Iowa Gambling Task. All participants showed initial weak performance, which improved only for patients in the SPB training condition. These results suggest that DM disorders in brain-damaged patients can be the consequence of their poor information processing strategy rather than an impairment in their DM abilities. Second, we showed that SPB could be efficient to normalize DM processes in brain injury patients.

description: Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic-hydrologic modeling framework that account~ for the interactions between water allocation, farmer input choice, agricultural productivity, non-agricultural water demand, and resource degradation in order to estimate the social and economic gains from improvement in the allocation and efficiency of water use. The model is applied to the Maipo river basin in Chile. Economic benefits to water use are evaluated for different demand management instruments, including markets in tradable water rights, based on production and benefit functions with respect to water for the agricultural and urban-industrial sectors. © 2000 Elsevier Science B.V.

description: Agricultural water conservation statutes are emerging in the West encouraging private irrigators to improve on-farm irrigation efficiency as a basinwide conservation measure. We investigate whether private improvements promote the economic efficiency and conservation of water use basinwide under a wide variety of hydroeconomic circumstances. The standard of efficiency is how an irrigation district manager should optimally invest in improving the irrigation efficiencies of individual farms located along a stream while internalizing intrabasin allocative externalities of these investments. The results indicate that the popular Oregon legislative model may be the least effective in conserving water and promoting economically efficient water allocation.© 2000 Elsevier Science B.V.

description: An internal solution to an optimal control problem involving conjunctive-use of surface and groundwater may be inapplicable if water is not sufficiently fungible across space and time. We provide a more general solution and apply it to the problem of allocating a limited amount of water from the Ko'olau mountains to two Oahu water districts separated by those mountains. The solution involves initially allocating all of the mountain water to the district supplied by groundwater but eventually allocating all of the water to the district supplied by surface water. The conditions for an internal solution hold only in the intervening years when some mountain water is allocated to each district. © 2000 Elsevier Science B.V. All rights reserved.

description: Ab initio MP2/aug’-cc-pVTZ calculations have been performed to determine selected stretching frequencies and chemical shieldings for ternary complexes N-base:PH2F:BeX2 and the corresponding binary complexes, with NH3, H2C=NH, and HCN as the nitrogen bases and H, F, and Cl as the substituents X. Be-F and P-F stretching frequencies depend on the Be-F and P-F distances, respectively, while P and F chemical shieldings depend on the N-P and P-F distances, respectively. The graph of the P chemical shieldings versus the P-F distance bears a remarkable resemblance to the graph of the P-F stretching frequencies versus that same distance. EOM-CCSD spin–spin coupling constants have also been evaluated for binary and ternary complexes. 1pJ(N-P) is negative at the longer N-P distances found in ternary complexes with HCN in which the N … P bond is a traditional pnicogen bond with some phosphorous-shared character, gains phosphorus-shared character as the N-P distance continues to decrease, and then becomes a phosphorous-transferred bond with ion-pair character at the shorter distances in the complexes with NH3 and H2C=NH. 1J(P-F) values are large and negative in complexes with HCN, but increase and become positive in complexes with H2C=NH and NH3 as the P-F distance increases.

description: In this paper, a series of novel 3-methyl-quinazolinone derivatives was designed, synthesised and evaluated for antitumor activity in vitro on wild type epidermal growth factor receptor tyrosine kinase (EGFRwt-TK) and three human cancer cell lines including A549, PC-3, and SMMC-7721. The results displayed that some of the compounds had good activities, especially 2-{4-[(3-Fluoro-phenylimino)-methyl]-phenoxymethyl}-3-methyl-3H-quinazolin-4-one (5 g), 2-{4-[(3,4-Difluoro-phenylimino)-methyl]-phenoxymethyl}-3-methyl-3H-quinazolin-4-one (5k) and 2-{4-[(3,5-Difluoro-phenylimino)-methyl]-phenoxymethyl}-3-methyl-3H-quinazolin-4-one (5 l) showed high antitumor activities against three cancer cell lines. Moreover, compound 5k could induce late apoptosis of A549 cells at high concentrations and arrest cell cycle of A549 cells in the G2/M phase at tested concentrations. Also, compound 5k could inhibit the EGFRwt-TK with IC50 value of 10 nM. Molecular docking data indicates that the compound 5k may exert inhibitory activity by forming stable hydrogen bonds with the R817, T830 amino acid residues and cation-Π interaction with the K72 residue of EGFRwt-TK.

description: We aimed to explore the changes in post-operative cognitive dysfunction (POCD) after gastrointestinal endoscopic treatment using detailed neuropsychological assessments. Patients hospitalized for gastrointestinal endoscopic polypectomy were recruited for neuropsychological evaluations, which included the Chinese version of the Mini-Mental State Examination (MMSE), Auditory-Verbal Learning Test, Digit Span Test (DST), Trail Making Task (TMT), Verbal Fluency Test, Clock Drawing Test, and Stroop test. Cognitive assessments were performed twice: one day before and 24 h after treatment. Healthy control subjects participated in the neuropsychological assessment during the same intervals. Detailed cognitive assessments were performed for 40 patients and 60 control subjects. Based on the Z scores, the incidence of POCD 24 h after gastrointestinal endoscopic treatment was 20%. Patients with POCD had significant impairment in the post-operative MMSE, forward DST, TMT, and Stroop interference effect correct count tests (all p < 0.05). Our preliminary results showed that patients were not fully recovered, and 20% had impairment in multiple cognitive assessments 24 h after a gastrointestinal endoscopy. As attention was affected, safety while discharging those patients should be a concern.

description: In many arid and semi-arid regions whether or not to desalinate seawater has long been a non-issue and policy debates are focused on the timing and extent of the desalination activities. We analyze how water scarcity and demand structure, on the one hand, and cost reduction via R&D programs, on the other hand, affect the desirable development of desalination technologies and the time profiles of fresh and desalinated water supplies. We show that the optimal R&D policy is of a non-standard most rapid approach path (NSMRAP) type, under which the state of desalination technology - the accumulated learning from R&D efforts - should approach a pre-specified target process as rapidly as possible and proceed along it thereafter. The NSMRAP property enables a complete characterization of the optimal water policy. The renewable nature of the fresh water stock permits a non-monotonic behavior of the optimal stock process: under certain conditions, the stock is depleted, to be (fully or partly) refilled at a later date. © 2000 Elsevier Science B.V.

description: We find the geometric phase of a two-level system undergoing pure dephasing via interaction with an arbitrary environment, taking into account the effect of the initial system-environment correlations. We use our formalism to calculate the geometric phase for the two-level system in the presence of both harmonic oscillator and spin environments, and we consider the initial state of the two-level system to be prepared by a projective measurement or a unitary operation. The geometric phase is evaluated for a variety of parameters such as the system-environment coupling strength to show that the initial correlations can affect the geometric phase very significantly even for weak and moderate system-environment coupling strengths. Moreover, the correction to the geometric phase due to the system-environment coupling generally becomes smaller (and can even be zero) if initial system-environment correlations are taken into account, thus implying that the system-environment correlations can increase the robustness of the geometric phase.

description: A common approach in modeling negotiations is to apply game theory to single issues. Recent work has suggested that the complexity of international negotiations can be better modeled by linking independent games. Successful linking is possible when the linked issues have compensating asymmetry of similar magnitude. An important result of linked games is that such games produce a greater feasible set of choices relative to the aggregated isolated games. In this paper, we demonstrate that achieving strict dominance of the linked game is not trivial and that results and implications depend on the structures of the isolated games. © 2000 Elsevier Science B.V.

description: We present three-dimensional (3D) electron-positron momentum densities in Mg and Cd, reconstructed from 2D angular correlation of annihilation radiation data. By folding densities from the extended momentum space into the first Brillouin zone, we separated Fermi surfaces in various bands. Our results are in good agreement with band structure LMTO calculations. In order to examine how many 1D profiles give us a possibility to reproduce the same details of the Fermi surfaces and Umklapp components of electron densities, various sets of 1D spectra were created for special directions in the Brillouin zone. Finally, corresponding 3D densities were reconstructed to show how many details one can get depending on the number of 1D profiles.

description: Of the twelve million people who live within 100 km of the US-Mexico border, 90 percent are clustered in trans boundary sister cities that share common water sources and pollution problems. New institutions created to address environmental concerns over NAFTA offer the promise of greater financial and technical assistance for water management in border cities. This paper reviews US-Mexico border water issues and institutions. Using insights from game theory, it draws policy lessons for institutions funding border water projects. We examine how the design of assistance programs, technical support, and pre-existing water rights and regulations affect project outcomes. The diversity and geographic dispersion of water conflicts suggests potential for applying the interconnected game approach to US-Mexico water negotiations. © 2000 Elsevier Science B.V.

Dazu wird zum einen der Bedeutung des Persönlichen in queer-/feministischer Theorie und Politik nachgegangen. Zum anderen wird gefragt, auf welche Weise das Persönliche in neoliberal gerahmter Populärkultur in Erscheinung tritt und ob es dadurch eine Ent-/Politisierung erfährt.

description: Reindeer husbandry is a cornerstone in the culture of the Sami, northern Scandinavia's indigenous people. This paper presents a dynamic, theoretical model of the Swedish reindeer husbandry and the market for reindeer meat, as well as econometric results based on three-stage least squares regression on annual data. The most striking feature of the empirical results is a "backward-sloping" supply function, which is consistent with the theoretical model. The results also show effects of the Chernobyl accident. Prevailing winds at the time of the accident carried radioactive fallout over the grazing areas for the Swedish reindeer husbandry, causing effects on both supply and demand.© 2001 Elsevier Science B.V.

Productivity Analysis

description: Many economists have advocated and applied total social factor productivity (TSFP) (i.e., total factor productivity estimated with both market and non-market inputs and externalities, and with all factors valued at social prices) as a single all-embracing measure of agricultural sustainability. This paper reviews the conceptual and practical issues in measuring TSFP and shows that no one measure alone will be theoretically or empirically robust as an indicator of sustainability. TSFP is a conceptually flawed measure since inclusion of non-market inputs and outputs and social price-based valuation, in most cases, violates the theoretical basis underlying those estimates. Trends in TSFP also have limited value in diagnosing the nature of sustainability problems, unless changes in productivity are related to underlying changes in technology, human and physical infrastructure, and indicators of resource quality. More attention needs to be given to defining key indicators of agro-ecosystem health and relating these measures to trends in productivity. This analysis must be sufficiently disaggregated and for a long enough time period to allow for spatial and temporal variability inherent in agricultural production. Secondary data at the district level on both conventional inputs and outputs and resource quality have recently allowed more quantitative estimates of sustainability and its causes. With limited data, yield growth decomposition analysis can often be used to provide valuable insights into sustainability problems. Meanwhile, there is a need to invest in long-term experimental and panel surveys offarmers and their fields for key production systems in order to provide long-term data that will allow full productivity accounting, using more formal statistical procedures. Regardless of the approach selected, the findings of this paper strongly suggest a need for economists, agronomists and soil scientists to collaborate in integrating approaches in order to provide more robust and informative measures of sustainability. © 2001 Elsevier Science B.V.

description: The water vapour line broadening (γ) and shifting (δ) coefficients for 212 lines of eight vibrational bands, namely, ν2 + ν3, 2ν2 + ν3, 3ν2 + ν3–ν2, 4ν2, ν1 + ν3, ν1 + ν2, ν1 + 2ν2 and 2ν1, in the 5800–6700 cm–1 spectral region induced by air are measured using Fourier transform infrared spectroscopy. The measurements are performed with a spectral resolution of 0.01 cm–1 and in a wide pressure range of air. The calculations of δ are based on the Anderson–Tsao–Curnutte theory. The measured γ values are combined with literature data for the half-widths found for the lines in the 380–14,000 cm–1 spectral region. The combined experimental data for N = 1386 measured γ coefficients of 17 vibrational bands of the H2O molecule perturbed by air are fitted to an empirical function. Two fitting procedures are used, with one considering the fit of the measured γ for individual rotational branches and the other considering the global fit of all 1386 measured γ. The computed γ values derived from the fitted parameters are compared statistically to the measurements. The vibrational dependence of the measured γ and their compatibility are discussed. The obtained fitted parameters of the empirical function are used for the analysis of γ for the lines in the 13,000 to 26,000 cm–1 spectral region.

description: Die Populärkultur des 21. Jahrhunderts hat neue Protagonist*innen: Influencer*innen. Auch Akteur*innen der Neuen Rechten nutzen die medialen Praktiken des Influencer-Marketings mit dem Ziel, kulturelle Hegemonie zu erlangen, indem sie apokalyptische Zeitdiagnosen propagieren und sich gleichzeitig als hoffnungsvollen Gegenentwurf stilisieren. Der Beitrag gibt Einblick in die medialen Praktiken rechter Influencerinnen. Anhand des rechten Typus der Tradwife wird herausgearbeitet, wie die Integration des ideologischen Traditionalismus in die moderne Plattformkultur vonstattengeht. Die Analyse zeigt, dass ‚Sinn für Ästhetik‘ zentrales Element im Branding von ‚traditioneller‘ Weiblichkeit ist und gleichzeitig als Scharnier zwischen den Logiken der Sozialen Medien und (neu)rechter Ideologie dient.

description: The variation of the activity coefficient of aqueous sulfuric acid with acid concentration, solution's temperature, and solvent's (water) dielectric constant, clearly fits a typical strong 1–3 electrolyte behaviour [Fraenkel, J. Phys. Chem. B. 116, 11662 (2012)]. Therefore, the aqueous acid was proposed to have the molecular formula H4SO5, and to dissociate to 3H+ (3H3O+) and 1HSO53−. When the above study was reported, electric conductivity data of the aqueous acid could not be theoretically interpreted to prove or disprove the 1–3 electrolyte behaviour, due to the lack of an appropriate conductance theory. The improved Debye–Hückel–Onsager (DHO) theory, DHO–SiS, recently reported [Fraenkel, Phys. Chem. Chem. Phys. 20, 29896 (2018)], allows, unlike its parent theory, a quantitative analysis of strong 1–1, 1–2 and 1–3 electrolytes. A good-to-excellent theory–experiment agreement is achieved for dilute aqueous H2SO4 at 0–50°C, but only if the acid is considered, as before, as a strong 1–3 electrolyte; the new analysis thus corroborates the previous activity-based findings. In contrast, the conductance of dilute sulfuric acid in pure methanol follows the conventional H2SO4 dissociation pattern, exhibiting a ‘mixed 1–1/1–2’ electrolyte behaviour.

description: The Web-based Executive Functioning Questionnaire (Webexec) is a brief scale developed to assess executive functions via online format. It has been used in different contexts, but its adaptation to other cultures is still restricted. This study aimed to perform a cross-cultural adaptation of the Webexec for a Brazilian sample considering the psychometric properties of the scale. This study used a sample of 295 Brazilian participants, with a mean age equal to 20.69 (SD = 6.030). This is a longitudinal study with reapplication of the scale six weeks after the test phase. Classical and contemporary methods were applied to analyze the psychometric properties of the Webexec. The results showed that the scale presented excellent psychometric properties for the Brazilian version, considering validity evidence based on the content and internal structure of Webexec, as well as reliability and precision. However, it is considered that other relational and experimental studies should be carried out with a larger sample size and for different population groups.

 Cnemidocarpa completa Kott 1985, p 124.
 Distribution
Previously recorded (see Kott 1985): Victoria (Deal I., Bass Strait); New South Wales (Arrawarra). New record: Tasmania (Port Davey, Bathurst Channel, 3–37 m, SAM E2879–81).
 Description
 The newly recorded specimens were attached to clumps of Pyura irregularis on a vertical rock wall. The individuals are conical with terminal branchial apertures and atrial apertures on short siphons halfway down the dorsum. The test is thin and flexible, encrusted with sand on the upper half, which has a warty appearance, the lower half being smooth and rounded. On the left are three to six gonads. Sometimes the anterior one divides and both branches continue around the pole of the gut loop. Seven to nine gonads are on the right. The body wall is thin and the branchial sac and gut, gonads, and endocarps are as previously described.
 Remarks
The new record confirms the temperate range of this species, which previously was known from Bass Strait to Arrawarra on the central New South Wales coast.

description: We propose a simple mathematical model that describes the time evolution of a self-propelled object on a liquid surface using such variables as the object location, the surface concentration of active molecules and the hydrodynamic surface flow. The model is applied to simulate the time evolution of a rotor composed of a polygonal plate with camphor pills at its corners. We have qualitatively reproduced results of experiments, in which the inversion of rotational direction under periodic stop-and-release operations was investigated. The model correctly describes the probability of the inversion as a function of the duration of the phase when the rotor is stopped. Moreover, the model allows to introduce the rotor asymmetry unavoidable in real experiments and study its influence on the studied phenomenon. Our numerical simulations have revealed that the probability of the inversion of rotational direction is determined by the competition among the transport of the camphor molecules by the flow, the intrinsic asymmetry of the rotor, and the noise amplitude.

The Schottky Conjecture and beyond

description: The `Schottky Conjecture' deals with the electrostatic field enhancement at the tip of compound structures such as a hemiellipsoid on top of a hemisphere. For such a 2-primitive compound structure, the apex field enhancement factor $γ_a^{(C)}$ is conjectured to be multiplicative ($γ_a^{(C)} = γ_a^{(1)} γ_a^{(2)}$) provided the structure at the base (labelled 1, e.g. the hemisphere) is much larger than the structure on top (referred to as crown and labelled 2, e.g. the hemi-ellipsoid). We first demonstrate numerically that for generic smooth structures, the conjecture holds in the limiting sense when the apex radius of curvature of the primitive-base $R_a^{(1)}$, is much larger than the height of the crown $h_2$ (i.e. $h_2/R_a^{(1)} \rightarrow 0$). If the condition is somewhat relaxed, we show that it is the electric field above the primitive-base (i.e. in the absence of the crown), averaged over the height of the crown, that gets magnified instead of the field at the apex of the primitive-base. This observation leads to the Corrected Schottky Conjecture (CSC), which for 2-primitive structures reads as $γ_a^{(C)}\simeq \langle γ_a^{(1)}\rangleγ_a^{(2)}$ where $\langle . \rangle$ denotes the average value over the height of the crown. For small protrusions ($h_2/h_1$ typically less than 0.2), $\langle γ_a^{(1)}\rangle$ can be approximately determined using the Line Charge Model so that $γ_a^{(C)} \simeq γ_a^{(1)}γ_a^{(2)} (2R_a^{(1)}/h_2)\ln(1 + h_2/2R_a^{(1)})$. The error is found to be within $1\%$ for $h_2/R_a^{(1)} < 0.05$, increasing to about $3\%$ (or less) for $h_2/R_a^{(1)} = 0.1$ and bounded below $5\%$ for $h_2/R_a^{(1)}$ as large as 0.5. The CSC is also found to give good results for 3-primitive compound structures. The relevance of the Corrected Schottky Conjecture for field emission is discussed.
