description: The present study presents a simple but effective method for 3D visualization of the two-phase flow in the micro-tube. An isosceles right-angle prism combined with a mirror located 45^o bevel to the prism is employed to obtain synchronously the front and side views of the flow patterns with a single camera, where the locations of the prism and the micro-tube for clearly imaging should satisfy a fixed relationship which is specified in the present study. The optical design is proven successfully by the tough visualization work at the cryogenic temperature range. The image deformation due to the refraction and geometrical configuration of the test section is quantitatively investigated. It is calculated that the image is enlarged by about 20% in inner diameter compared to the real object, which is validated by the experimental results. Meanwhile, the image deformation by adding a rectangular optical correction box outside the circular tube is comparatively investigated. It is calculated that the image is reduced by about 20% in inner diameter with a rectangular optical correction box compared to the real object. The 3D re-construction process based on the two views is conducted through three steps, which shows that 3D visualization method can be easily applied for two-phase flow research in micro-scale channels and improves the measurement accuracy of some important parameters of two-phase flow such as void fraction, spatial distribution of bubbles, etc..

description: Transformers have revolutionized modern applications but are costly as model sizes grow. This thesis targets efficient training and inference of large Transformer models. We first explore allocating trainable parameters to task-specific positions to boost performance for parameter-efficient fine-tuning (PEFT). We then tailored PEFT efficiently to generate a range of fine-tuned models meeting various hardware constraints through model stitching. Additionally, we offer a novel pruning approach reconfiguring expensive self-attention layers into efficient convolutional layers, creating compact hybrid models. For semantic segmentation, we develop efficient cross-attention layers and a dynamic positional query design, achieving state-of-the-art performance with affordable costs.

description: Clausilioides Lindholm, 1925 Clausilioides Lindholm, 1925: 29, 38. Type species (by monotypy): Buliminus (Brephulus) biplicatus Retowski, 1889. So far, only two species have been assigned to the genus Clausilioides, namely C. biplicatus (Retowski, 1889) (synonym: eplicatus Lindholm, 1913) and C. filifer (Lindholm, 1913). We here describe another two species. The genus seems to be endemic for the northeastern part of Turkey, although both biplicatus and filifer have originally been described from Georgia (but only found in deposition of the Çoruh river). A characteristic feature of the genus is the presence of a well developed palatal fold in the last whorl. This is a rare character within the family Enidae. It has been reported in Pseudonapaeus entoptyx (Lindholm, 1925) (the type species of Siraphorus Lindholm, 1925), Siraphoroides moltschanovi (Likharev & Rammelmeier, 1952) (a monotypic genus), and various species of the genus Pupopsis Gredler, 1898. The first two species are known from Kirgizstan, whereas Puposis is distributed in the northwestern part of China (Xinjiang at the border of Kirgistan and Kazachstan) as well as in central China (SE Gansu and N Sichuan). For a review on Pupopsis see Wu & Gao (2010). Furthermore, a palatal fold is seen in Buliminus glabratus (Mousson, 1861) from the central part of Israel.

description: We show that deciding whether a sparse univariate polynomial has a p-adic rational root can be done in NP for most inputs. We also prove a polynomial-time upper bound for trinomials with suitably generic p-adic Newton polygon. We thus improve the best previous complexity upper bound of EXPTIME. We also prove an unconditional complexity lower bound of NP-hardness with respect to randomized reductions for general univariate polynomials. The best previous lower bound assumed an unproved hypothesis on the distribution of primes in arithmetic progression. We also discuss how our results complement analogous results over the real numbers.

description: My purpose is not an appraisal of Sraffa's work or a probing into his aims or philosophy. I want to deal with a particular aspect. Sraffa's book is concerned with measurement, concepts, aggregation. Indeed, a good deal of the intellectual difficulties which he has mastered are precisely in this field. He had to find a concept which would make it possible to deal with a multi-commodity economy in the same way as if it were a corn economy (one commodity economy of Ricardo). He foud the concept in the standard cmmodity. It is an aggregate and yet a physical measure like corn, independent of prices and distribution. It may serve to measure consumption and investement, wages and profits alike. It is a macro-economic concept derived from data for individual commodities. (Auszug, S. 1) Description of the book provided by www.abebooks.com (21.03.2017): "This volume contains the proceedings of an economics conference held in Florence, Italy in August 1985, to celebrate the 25th anniversary of the publication of Piero Sraffa's "Production of Commodities by Means of Commodities", a pioneering work which opened up debates on the fundamental issues in economic theory. The purpose of the conference was to elucidate some of the basic issues in theory and to assess the efforts needed to develop the classical approach to economic analysis and its extensions in applied fields. The conference invited the main participants in these debates to contribute papers whereby they could elaborate their interpretations of Sraffa's work and evaluate its impact on the present economic theory. All key papers and two round tables of discussion are included in the text."

description: The magnetic ground state of BaFe12O19 (BFO) was investigated using X-ray absorption at 1.2 K and 1.5 K, respectively. The XMCD measurements on single-crystals of BFO in grazing incidence geometry reveal the canting of the spins away from the c-axis of the hexagonal unit cell. Single-crystal neutron diffraction studies reveal magnetic satellite peaks along the 00l reciprocal lattice row around the forbidden l = 2n +/- 1 positions confirming conical-type magnetic structure in the ground state of BFO. The observation of the conical magnetic structure of BFO opens the possibility of type-II multiferroicity in undoped BFO also.

Subjects: SECS-P/01 Economia politica

description: In recent years, a large body of empirical research has investigated whether the predictions of secondgeneration growth models are consistent with actual data. This strand of literature has focused on the longrun properties of these models by using productivity and innovation data but has not directly assessed the effectiveness of R&D policy in promoting innovation and economic growth. In the present paper, we fill this gap in the literature by providing a unified growth setting that is empirically tested with US manufacturing industry data. Our analysis shows that R&D policy has a persistent, if not permanent, impact on the rate of economic growth and that the economy rapidly adjusts to policy changes. The impact of R&D tax credits on economic growth appears to be long lasting and statistically robust. Conversely, more generous R&D subsidies are associated with an increase in the rate of economic growth in the short run only, indicating that, at best, this policy instrument has only temporary effects. Overall, the evidence regarding the effectiveness of R&D policy provides more support for fully endogenous growth theory than for semi-endogenous growth theory.

The first is an additional contribution to the background in the measurement of the yield of electrons at mid-rapidity from open heavy flavor decays. We found that the $J/Ψ$ can contribute substantially to the yield at high $p_T$. PHENIX has also measured the spectrum of muons at forward rapidity from open heavy flavor decays in Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV.

The regional districts of British Columbia
Creators: name: Nicholson, Theodore Joseph
Publisher: name: University of British Columbia
Year: 2010

description: Regional planning is one of the functions most often affected by the dilemma of how to provide services and resolve conflicts that transcend municipal boundaries. Most existing solutions, while they accept the consensus that power should be decentralized, have limited applicability and the greatest need is for institutional innovations.-This report critically examines such an innovation — the regional districts introduced by British Columbia in 1965. The hew concept employs the identical institutional framework td provide regional services riot only in metropolitan alia non-metropolitan municipalities, but also in the unorganized areas which cover more than 98 percent of the province. A review of the literature led to the conclusion that before a province introduces regional institutions it should consider five key factors. These were: the selection of criteria to delimit administrative boundaries; participation by local governments and by citizens; coordination with other levels of government; the delegation of adequate powers; and the flexibility to adapt to different conditions. Regional districts were evaluated in this context. The inductive approach chosen to generate data documents the history of regional planning and regional districts in the province, then analyzes five of the districts in more detail, and finally solicits the views of the directors of the regional boards. The latter form a second tier or federation of local areas governed by locally elected representatives. The study concludes that the size or configuration of the districts is not always rational, that the provision for local participation is satisfactory but, with the exception of inter-municipal liason, the coordination of programs with provincial departments is not. Most of the power delegated to regional districts appears to be really a transfer of powers from local governments, with the exception of powers acquired by residents of unorganized areas. The flexibility of the new system was judged to be its outstanding feature. A conspicuous phenomenon was the speed with which regional districts were volutarily adopted. It was concluded the tactics employed by the province to "sell" the concept, together with the impetus provided by linking hospital financing to regional districts through complementary legislation were important contributing factors. The failure to provide any overall provincial planning policies with which the programs of the regional districts might have been integrated was perceived as a major weakness. A summary of legislation adopted by three other provinces is included to illustrate the diversity of potential solutions available within Canada's form of federation. The report does not consider regional economic planning, the property tax, the role of the planner, or liason between various levels of government are within its terms of reference, although brief comments on all of these are made on occasion.

description: The advanced large language model (LLM) ChatGPT has shown its potential in different domains and remains unbeaten due to its characteristics compared to other LLMs. This study aims to evaluate the potential of using a fine-tuned ChatGPT model as a personal medical assistant in the Arabic language. To do so, this study uses publicly available online questions and answering datasets in Arabic language. There are almost 430K questions and answers for 20 disease-specific categories. GPT-3.5-turbo model was fine-tuned with a portion of this dataset. The performance of this fine-tuned model was evaluated through automated and human evaluation. The automated evaluations include perplexity, coherence, similarity, and token count. Native Arabic speakers with medical knowledge evaluated the generated text by calculating relevance, accuracy, precision, logic, and originality. The overall result shows that ChatGPT has a bright future in medical assistance.

description: There is a fundamental connection between temperature-quenched 2D superfluids and 2D quantum turbulence: the mechanism responsible for the decay of the vorticity after the quench is the enstrophy cascade of 2D turbulence. The range of the cascade is shown to increase with time after the quench as $t^{1/2}$, being equal to the dynamic scaling length characterizing the quench. These results may apply to other phase-ordering transitions involving the decay of topological objects.

description: We study Landau-gauge gluon and ghost propagators in Yang-Mills theories at lattice parameter beta = 0, considering relatively large lattice volumes for the case of the SU(2) gauge group in three and four space-time dimensions. We compare the lattice data to the so-called massive and conformal-scaling solutions, examining the requirements for a good description of the propagators over various ranges of momenta and discussing possible systematic errors. Our analysis strongly supports the massive solution, i.e. a finite gluon propagator and an essentially free ghost propagator in the infrared limit, in disagreement with Ref. [1]. Moreover, we argue that discretization effects play no role in the analysis of these propagators.

description: The world of communication has changed quickly in the last decade resulting in the the rapid increase in the pace of peoples’ lives. This is due to the explosion of mobile communication and the internet which has now reached all levels of society. With such pressure for access to communication there is increased demand for bandwidth. Photonic technology is the right solution for high speed networks that have to supply wide bandwidth to new communication service providers. In particular this Ph.D. dissertation deals with DWDM optical packet-switched networks. The issue introduces a huge quantity of problems from physical layer up to transport layer. Here this subject is tackled from the network level perspective. The long term solution represented by optical packet switching has been fully explored in this years together with the Network Research Group at the department of Electronics, Computer Science and System of the University of Bologna. Some national as well as international projects supported this research like the Network of Excellence (NoE) e-Photon/ONe, funded by the European Commission in the Sixth Framework Programme and INTREPIDO project (End-to-end Traffic Engineering and Protection for IP over DWDM Optical Networks) funded by the Italian Ministry of Education, University and Scientific Research. Optical packet switching for DWDM networks is studied at single node level as well as at network level. In particular the techniques discussed are thought to be implemented for a long-haul transport network
that connects local and metropolitan networks around the world. The main issues faced are contention resolution in a asynchronous variable packet length environment, adaptive routing, wavelength conversion and node architecture. Characteristics that a network must assure as quality of service and resilience are also explored at both node and network level. Results are mainly evaluated via simulation and through analysis.
Dynamics and stability conditions of semiconductor lasers under external optical feedback from both sides of the laser cavity

Publisher: name: arXiv
Year: 2021
Subjects: subject: Optics (physics.optics)

description: To increase the spectral efficiency of coherent communication systems, lasers with ever-narrower linewidths are required as they enable higher-order modulation formats with lower bit-error rates. In particular, semiconductor lasers are a key component due to their compactness, low power consumption, and potential for mass production. In field-testing scenarios their output is coupled to a fiber, making them susceptible to external optical feedback (EOF). This has a detrimental effect on its stability, thus it is traditionally countered by employing, for example, optical isolators and angled output waveguides. In this work, EOF is explored in a novel way with the aim to reduce and stabilize the laser linewidth. EOF has been traditionally studied in the case where it is applied to only one side of the laser cavity. In contrast, this work gives a generalization to the case of feedback on both sides. It is implemented using photonic components available via generic foundry platforms, thus creating a path towards devices with high technology-readiness level. Numerical results shows an improvement in performance of the double-feedback case with respect to the single-feedback case. In particularly, by appropriately selecting the phase of the feedback from both sides, a broad stability regime is discovered. This work paves the way towards low-cost, integrated and stable narrow-linewidth integrated lasers.

description: We present recent improvements to the search for the global Cosmic Dawn signature using the Long Wavelength Array station located on the Sevilleta National Wildlife Refuge in New Mexico, USA (LWA-SV). These improvements are both in the methodology of the experiment and the hardware of the station. An improved observing strategy along with more sophisticated temperature calibration and foreground modelling schemes have led to improved residual RMS limits. A large improvement over previous work using LWA-SV is the use of a novel achromatic beamforming technique which has been developed for LWA-SV. We present results from an observing campaign which contains 29 days of observations between March $10^{\rm{th}}$, 2021 and April $10^{\rm{th}}$ 2021. The reported residual RMS limits are 6 times above the amplitude of the potential signal reported by the Experiment to Detect the Global EoR Signature (EDGES) collaboration.

description: Lepton and quark flavor invariants are studied, both in the Standard Model with a dimension five Majorana neutrino mass operator, and in the seesaw model. The ring of invariants in the lepton sector is highly non-trivial, with non-linear relations among the basic invariants. The invariants are classified for the Standard Model with two and three generations, and for the seesaw model with two generations, and the Hilbert series is computed. The seesaw model with three generations proved computationally too difficult for a complete solution. We give an invariant definition of the CP-violating angle theta in the electroweak sector.

description: Motivated by second order asymptotic results, we characterize the convergence in law of double integrals, with respect to Poisson random measures, toward a standard Gaussian distribution. Our conditions are expressed in terms of contractions of the kernels. To prove our main results, we use the theory of stable convergence of generalized stochastic integrals developed by Peccati and Taqqu. One of the advantages of our approach is that the conditions are expressed directly in terms of the kernel appearing in the multiple integral and do not make any explicit use of asymptotic dependence properties such as mixing. We illustrate our techniques by an application involving linear and quadratic functionals of generalized Ornstein--Uhlenbeck processes, as well as examples concerning random hazard rates.

description: Creativity is a critical skill that professional software engineers leverage to tackle difficult problems. In higher education, multiple efforts have been made to spark creative skills of engineering students. However, creativity is a vague concept that is open to interpretation. Furthermore, studies have shown that there is a gap in perception and implementation of creativity between industry and academia. To better understand the role of creativity in software engineering (SE), we interviewed 33 professionals via four focus groups and 10 SE students. Our results reveal 45 underlying topics related to creativity. When comparing the perception of students versus professionals, we discovered fundamental differences, grouped into five themes: the creative environment, application of techniques, creative collaboration, nature vs nurture, and the perceived value of creativity. As our aim is to use these findings to install and further encourage creative problem solving in higher education, we have included a list of implications for educational practice.

description: A rotating ultracold S-wave superfluid Fermi gas is considered, when the population imbalance (or equivalently the mismatch in chemical potentials) corresponds to the Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) state in the vicinity of the Lifshitz critical point. It is shown that under these conditions the critical angular velocity in two-dimensional systems is an oscillating function of temperature and population imbalance giving rise to reentrant superfluid phases. This leads to vortex lattices with multiple-quantized circulation quanta. The reason for this behavior is the population by Cooper pairs of the Landau levels above the lowest one.

description: This study evaluates ChatGPT's performance in annotating vaccine-related Arabic tweets by comparing its annotations with human annotations. A dataset of 2,100 tweets representing various factors contributing to vaccine hesitancy was examined. Two domain experts annotated the data, with a third resolving conflicts. ChatGPT was then employed to annotate the same dataset using specific prompts for each factor. The ChatGPT annotations were evaluated through zero-shot, one-shot, and few-shot learning tests, with an average accuracy of 82.14%, 83.85%, and 85.57%, respectively. Precision averaged around 86%, minimizing false positives. The average recall and F1-score ranged from 0.74 to 0.80 and 0.65 to 0.93, respectively. AUC for zero-shot, one-shot, and few-shot learning was 0.79, 0.80, and 0.83. In cases of ambiguity, both human annotators and ChatGPT faced challenges. These findings suggest that ChatGPT holds promise as a tool for annotating vaccine-related tweets.

description: The first supersoft source (SSS) identification with an optical nova in M 31 was based on ROSAT observations. Twenty additional X-ray counterparts (mostly identified as SSS by their hardness ratios) were detected using archival ROSAT, XMM-Newton and Chandra observations obtained before July 2002. Based on these results optical novae seem to constitute the major class of SSS in M 31. An analysis of archival Chandra HRC-I and ACIS-I observations obtained from July 2004 to February 2005 demonstrated that M 31 nova SSS states lasted from months to about 10 years. Several novae showed short X-ray outbursts starting within 50 d after the optical outburst and lasting only two to three months. The fraction of novae detected in soft X-rays within a year after the optical outburst was more than 30%. Ongoing optical nova monitoring programs, optical spectral follow-up and an up-to-date nova catalogue are essential for the X-ray work. Re-analysis of archival nova data to improve positions and find additional nova candidates are urgently needed for secure recurrent nova identifications. Dedicated XMM-Newton/Chandra monitoring programs for X-ray emission from optical novae covering the center area of M 31 continue to provide interesting new results (e.g. coherent 1105s pulsations in the SSS counterpart of nova M31N 2007-12b). The SSS light curves of novae allow us - together with optical information - to estimate the mass of the white dwarf, of the ejecta and the burned mass in the outburst. Observations of the central area of M 31 allow us - in contrast to observations in the Galaxy - to monitor many novae simultaneously and proved to be prone to find many interesting SSS and nova types.

description: It has been proved in \cite{ge} for every $p$-group of order $p^n$, $|\mathcal{M}(G)|=p^{\f{1}{2}n(n-1)-t(G)}$, where $t(G)\geq 0$. In \cite{be, el, zh}, the structure of $G$ has been characterized for $t(G)=0,1,2,3$ by several authors. Also in \cite{sa}, the structure of $G$ characterized when $t(G)=4$ and $Z(G)$ is elementary abelian. This paper is devoted to classify the structure of $G$ when $t(G)=4$ without any condition.
Hydrogen and Helium Shock Phenomena during Rising Light in RR Lyrae Fundamental Mode Pulsators

description: We present measurements of H and He emission and absorption lines produced in RRab fundamental mode pulsators during primary light rise. The lines define universal progressions of rise and decay in metal-poor RRab stars. Such a progression cannot be constructed for He in metal-rich RRab (those with [Fe/H]> -0.8) because weak He I emission is detected in only two of the six metal-rich RRab in our survey. Great variety exists in the phase variations of the blue- and red-shifted absorption components of the 5876 A line during pre- and post-emission phases. Detection of measurable He II 4686 A emission in eight RRab, three of them Blazhko variables, provides an additional constraint on ionization of Helium.

description: Amphiscopus moolenbeeki spec. nov. (Fig. 14) Type locality & type material. – Turkey, Vilayet Tokat, Reşadiye, 8 km towards Çekerek, 770 m (40.1523°N 35.6320°E), H.P.M.G. Menkhorst leg., 19.vii.1990. Holotype NMBE 544668, paratypes NMBE 544669/2, HMK/>50, RBA/3, RMNH/3, ZMH/3. Diagnosis. – A large, highly turreted Amphiscopus species without a parietalis or palatalis superior. Description. – Shell dextral, highly turreted, with an open, slit-like umbilicus. The 10.4-13.2 whorls are convex with a moderately deep suture. Teleoconch with widely spaced, fine, oblique striae; there are no spiral striae. Shell solid, not translucent, glossy, uniformly horny yellow coloured, with a prominent whitish band behind the peristome. Peristome not or hardly reflected (with the exception of the columellar part), thickened by a labial callus, the columellar and palatal insertion connected by a clearly visible callus which is quite thickened near the columellar peristome. The edge of the palatal insertion forms a wide arc. The dot-like to tear-like subangularis is connected with the palatal peristome by a thin callus. There is no parietalis, spiralis, palatalis superior, infrapalatalis, basalis or columellaris. The columellar ledge reaches halfway or above the middle of the columellar side of the aperture. Measurements (n = 8). – H = 10.0-14.4 (mean 12.3); LWH = 4.0-4.8 (mean 4.3); MH = 2.6-2.9 (mean 2.7); LWD = 3.0-3.3 (mean 3.1); LWM = 2.9-3.3 (mean 3.1); MD = 1.9-2.2 (mean 2.1); NW = 10.4-13.2 (mean 11.9). Localities. – Vilayet Tokat: type locality (see above); Reşadiye, 7.5 km towards Çekerek (HMK/1). Derivatio nominis. - Named after our friend Rob(ert) Moolenbeek, who made numerous important malacological contributions and who curated the molluscan collection of the formerly Zoologisch Museum Amsterdam for decades (now integrated in the Naturalis Biodiversity Center, Leiden). Remarks. – This taxon has been assigned to Amphiscopus because of the overall shape of the shell, the small aperture and the thickened peristome. So far, only the species sturmii and substurmii has been assigned Amphiscopus; therefore moolenbeeki is now the third known Amphiscopus species. It can be easily recognized from A. sturmii and A. substurmii by the characters mentioned in the diagnosis.
