description: Karst in Southwest China, recognized as biodiversity hotspots, exhibit heightened sensitivity to climate change. The effects of climate change on these ecosystems via species distribution and population genetics remain inadequately investigated. This study examines the karst-endemic amphibian Odorrana kweichowensis by analyzing population structure, evolutionary history, and habitat range. Integrating species distribution modeling with population genetics, we assessed potential habitat and diversity loss under four greenhouse gas emission scenarios.

A class of algorithms for simulating the Schrodinger equation for interacting many-body systems are presented in some detail. These algorithms would make it possible to simulate nonrelativistic quantum systems on a quantum computer with an exponential speedup compared to simulations on classical computers. Issues involved in simulating relativistic systems of Dirac and gauge particles are discussed.

description: We show the utility of photon added-then-subtracted (PAS) state and two photon replaced (2PR) state when used in continuous variables measurement device independent quantum key distribution (CV-MDI-QKD) protocol. We report that single and two mode PAS state as well as two mode PR state outperform pure state protocol in the low squeezing and high noise regime. Single mode PAS state and two mode PAS state showed significant resilience to excess noise and offered a longer transmission distance when compared to pure and PR state CV-MDI protocol. Additionally we show that states with higher logarithmic negativity are not necessarily the best choice when used in CV-MDI-QKD.

Invariant deep neural networks under the finite group for solving partial differential equations

description: Utilizing physics-informed neural networks (PINN) to solve partial differential equations (PDEs) becomes a hot issue and also shows its great powers, but still suffers from the dilemmas of limited predicted accuracy in the sampling domain and poor prediction ability beyond the sampling domain which are usually mitigated by adding the physical properties of PDEs into the loss function or by employing smart techniques to change the form of loss function for special PDEs. In this paper, we design a symmetry-enhanced deep neural network (sDNN) which makes the architecture of neural networks invariant under the finite group through expanding the dimensions of weight matrixes and bias vectors in each hidden layers by the order of finite group if the group has matrix representations, otherwise extending the set of input data and the hidden layers except for the first hidden layer by the order of finite group. However, the total number of training parameters is only about one over the order of finite group of the original PINN size due to the symmetric architecture of sDNN. Furthermore, we give special forms of weight matrixes and bias vectors of sDNN, and rigorously prove that the architecture itself is invariant under the finite group and the sDNN has the universal approximation ability to learn the function keeping the finite group. Numerical results show that the sDNN has strong predicted abilities in and beyond the sampling domain and performs far better than the vanilla PINN with fewer training points and simpler architecture.

Subjects: subject: Child protection recurrence

subject: Child protection services

description: Child protection recurrence exists where children and families have repeated involvement with authorities responsible for preventing and addressing harm caused by child maltreatment. Prior research has examined repeated reports, repeated investigations, and repeated substantiations of child maltreatment. Child protection recurrence is problematic for children, as concerns about abuse or neglect remain unresolved despite repeated contact with child protection authorities. For families, repeated investigations can be experienced as invasive, stressful, and stigmatising. For governments, recurrence represents repeated work screening and possibly investigating allegations about the same children and families. It also raises questions about the accuracy of risk assessments designed to prioritise services, and the effectiveness of interventions designed to prevent further maltreatment. Child protection recurrence therefore raises questions about the effectiveness and efficiency of child protection services.

description: Understanding and accurately predicting hydrogen diffusion in materials is challenging due to the complex interactions between hydrogen defects and the crystal lattice. These interactions span large length and time scales, making them difficult to address with standard ab initio techniques. This work addresses this challenge by employing accelerated machine learning (ML) molecular dynamics simulations through active learning. We conduct a comparative study of different ML-based interatomic potential schemes, including VASP, MACE, and CHGNet, utilizing various training strategies such as on-the-fly learning, pre-trained universal models, and fine-tuning.By considering different temperatures and concentration regimes, we obtain hydrogen diffusion coefficients and activation energy values which align remarkably well with experimental results, underlining the efficacy and accuracy of ML-assisted methodologies in the context of diffusive dynamics. Particularly, our procedure significantly reduces the computational effort associated with traditional transition state calculations or ad-hoc designed interatomic potentials. The results highlight the limitations of pre-trained universal solutions for defective materials and how they can be improved by fine-tuning. Specifically, fine-tuning the models on a database produced during on-the-fly training of VASP ML force-field allows the retrieving of DFT-level accuracy at a fraction of the computational cost.

description: In a series of publications we developed "differential geometry" on discrete sets based on concepts of noncommutative geometry. In particular, it turned out that first order differential calculi (over the algebra of functions) on a discrete set are in bijective correspondence with digraph structures where the vertices are given by the elements of the set. A particular class of digraphs are Cayley graphs, also known as group lattices. They are determined by a discrete group G and a finite subset S. There is a distinguished subclass of "bicovariant" Cayley graphs with the property that ad(S)S is contained in S. We explore the properties of differential calculi which arise from Cayley graphs via the above correspondence. The first order calculi extend to higher orders and then allow to introduce further differential geometric structures. Furthermore, we explore the properties of "discrete" vector fields which describe deterministic flows on group lattices. A Lie derivative with respect to a discrete vector field and an inner product with forms is defined. The Lie-Cartan identity then holds on all forms for a certain subclass of discrete vector fields. We develop elements of gauge theory and construct an analogue of the lattice gauge theory (Yang-Mills) action on an arbitrary group lattice. Also linear connections are considered and a simple geometric interpretation of the torsion is established. By taking a quotient with respect to some subgroup of the discrete group, generalized differential calculi associated with so-called Schreier diagrams are obtained.

subject: Visible Light Active Nanostructure Photocatalysts

subject: Decomposition of biohazards

description: Rapid disinfection and effective removal of biohazards from water is important and necessary for safeguarding water, due to availing public health and environmental concerns. To achieve this aim, many techniques such as ultraviolet, chlorination, ultrasonic and ozone have been widely investigated and employed, though there are many drawbacks in these methods which are becoming more problematic in the developing world. In recent decades, two advanced oxidation techniques, photocatalysis (PC) and photoelectrocatalysis (PEC), have drawn extensive attentions, as they have displayed great potentials to be more sustainable, affordable, safer and robust for water purification technologies. There are still many issues however need to be solved, such as the identification of reaction intermediates, development of rate expressions and the photocatalytic efficiencies of the photocatalysts are still far from satisfaction. Therefore, it is necessary to develop high efficiency photocatalysts and study the fundamental mechanisms in the PC and PEC processes. In this thesis, three types of UV and/or visible light active nanostructured TiO2 films with different structures and crystal phases have been developed, the fundamental aspects such as the electron transport properties in the photocatalyst films have been studied in detail, and the disinfection and decomposition performances of the obtained photocatalysts against Escherichia coli (E. coli) bacteria have been investigated. To achieve these objectives, systematic studies have been performed including the establishment of experimental methodology, characterisations of nanomaterials, performance evaluation and mechanistic aspects.

description: In earlier papers we showed that a frame dependent effective action motivated by the postulates of three-space general coordinate invariance and Weyl scaling invariance exactly mimics a cosmological constant in Friedmann-Robertson-Walker (FRW) spacetimes, but alters the linearized equations governing scalar perturbations around a spatially flat FRW background metric. Here we analyze the implications of a frame dependent dark energy for the spacetime cosmological metric within both a perturbative and a non-perturbative framework. Both methods of calculation give a one-parameter family of cosmologies which are in close correspondence to one another, and which contain the standard FRW cosmology as a special case. We discuss the application of this family of cosmologies to the standard cosmological distance measures and to the effective Hubble parameter, with special attention to the current tension between determinations of the Hubble constant at late time, and the Hubble value obtained through the cosmic microwave background (CMB) angular fluctuation analysis.

Closed expressions for the Lax operators in terms of superfield eigenfunctions are obtained. All hierarchy equations being eigenfunction equations are shown to be automatically invariant under the (extended) supersymmetry. The supersymmetric Lax models existing in the literature are found to be contained (up to a gauge equivalence) in our formalism.

description: The olfactory mucosa has been shown to be a site where continual regeneration takes place throughout adulthood, making this system relatively unique with great potential in respect to autologous cell graft therapies. The olfactory mucosa is readily accessible with no deleterious effects on olfaction if biopsied. The presence of olfactory ensheathing cells (OECs), as well as a stem cell to facilitate the regeneration of this tissue, has been previously described. The first aim of this study was to further characterise olfactory ensheathing cells in rat and human and to gain some insights into their biology in vitro and in vivo, with the hope of applying this knowledge to clinical therapies employing autologous cell grafts. The second aim was to isolate stem cells in the form of neurospheres from the adult olfactory lamina propria, to elucidate their differentiation potential into both neural and non neural lineages, and to subsequently graft these cells into animal models of spinal cord injury to assess their behaviour in vivo in regards to survival, proliferation, and integration into the host spinal cord. Recovery of locomotor function due to axon regeneration across the lesion site following grafting was also assessed. Glial cells isolated from the adult olfactory lamina propria were identified as OECs in vitro and in vivo using the immunological markers GFAP, S100, and p75NTR. Neurotrophin growth factors were shown to promote their proliferation and purification in vitro from both rat and human. Immunocytochemistry and PCR were used to confirm the expression of neurotrophin trk receptors A, B, and C, as well as NT3, NGF and BDNF by OECs in rat and human. NT3 was shown to purify adult human OECs in vitro. Through the use of EGF and FGF2, it was shown that the olfactory lamina was capable of generating neurospheres consisting of a heterogeneous cell population, containing fully differentiated cells, progenitor cells, as well as undifferentiated stem cells indentified by the markers nestin and c-kit. Using growth factors, single or in combination, as well as tissue conditioned medium, olfactory stem cells within these neurospheres were induced to differentiate into the neural lineage, namely neurons, astrocytes, and oligodendrocytes. Non neural differentiation into liver, skeletal muscle, and cardiac cells was induced in vitro by cell-cell contact between neurospheres and frozen rat tissue sections.

description: We introduce first-time sensitivity for a homeomorphism of a compact metric space, that is a condition on the first increasing times of open balls of the space. Continuum-wise expansive homeomorphisms, the shift map on the Hilbert cube, and also some partially hyperbolic diffeomorphisms satisfy this condition. We prove the existence of local unstable continua satisfying similar properties with the local unstable continua of cw-expansive homeomorphisms, but assuming first-time sensitivity. As a consequence we prove that first-time sensitivity (with some additional technical assumptions) implies positive topological entropy.

The Politics of China-Orientated Nationalism in Colonial Hong Kong 1949-1997: A History
Creators: name: Chun, Michael Hon-Chung
Publisher: name: The Australian National University
Year: 2010
Subjects: Nationalism, China, Hong Kong, China-orientated nationalism, colonialism, Chinese Communist Party, Guomindang, Tiananmen Square

description: This thesis is the first comprehensive study of the history of China-orientated nationalism in post-World War II (WWII) colonial Hong Kong. The thesis examines events in each decade diachronically and links them together in a broader perspective. It shows the continuities and changes in the meaning and politics of China-orientated nationalism and how the focus of that nationalism became increasingly on what was happening in Hong Kong rather than China in the long period from 1949 to 1997. Three types of China-orientated nationalism emerged in Hong Kong during the 1949-1997 period: cultural nationalism, political nationalism, and popular nationalism. Some of the exiled Chinese intellectuals in the 1950s promoted cultural nationalism, while political nationalism in Hong Kong revolved around the Chinese Communist Party-Guomindang (CCP-GMD) struggle. Popular nationalism in the post-1967 period was tied primarily to Hong Kong politics. This thesis demonstrates how the various nationalist sentiments were a product of the China factor, the Hong Kong factor, and colonialism. China-orientated nationalism was open to interpretation and its rise and evolution was a haphazard process. Over time, the rhetoric of political nationalism that revolved around the CCP-GMD struggle became less significant as younger generations of Hong Kong Chinese who had little interest in Chinese politics became politically active in the 1970s. In this new phase, nationalism was tied not to the pro-CCP/pro-GMD rhetoric of the 1950s and 1960s, but to young Hong Kong peoples concern about problems in Hong Kong society and Hong Kong politics. In the 1980s and 1990s, expressions of popular nationalism were linked to Hong Kong peoples concern over the future of Hong Kong following the Tiananmen Square incident and on the eve of the 1997 handover. This study of the evolution of China-orientated nationalism in colonial Hong Kong also provides an understanding of how the colonial government responded, and how some sectors of the Hong Kong Chinese community manoeuvred vis-Ã -vis the colonial administration and other Hong Kong-based groups by using their own strategically constructed nationalism.

description: The sparsity and the severe attenuation of millimeter-wave (mmWave) channel imply that highly directional communication is needed. The narrow beam produced by large array requires accurate alignment, which is difficult to achieve when serving fast-moving users. In this paper, we focus on accurate two-dimensional (2D) beam and channel tracking problem aiming at minimizing exploration overhead and tracking error. Using a typical frame structure with periodic exploration and communication, a proven minimum overhead of exploration is provided first. Then tracking algorithms are designed for three types of channels with different dynamic properties. It is proved that the algorithms for quasi-static channels and channels in Dynamic Case I are optimal in approaching the minimum Cramer-Rao lower bound (CRLB). The computational complexity of our algorithms is analyzed showing their efficiency, and simulation results verify their advantages in both tracking error and tracking speed.

Therapeutic Potential of Platelet rich fibrin- A novel autologous platelet concentrate for regenerative veterinary medicine
Creators: name: 1Dr. Mamta Mishra, 2Dr. Neelam Kushwaha, 3Dr. Anand Mohan
Publisher: name: The Science world a Monthly e magazine
Year: 2024

description: Platelet-rich fibrin (PRF), a novel biomaterial designed for easier manufacturing without biochemical blood processing and resembling an autologous cicatricial matrix, is a member of the recent wave of platelet concentrates. Any surgical or regenerative procedure in animals ultimately aims to promote wound healing and tissue regeneration. This process's efficiency stems from the local and continuous supply of a diverse variety of growth factors and proteins, which replicate the requirements of physiological wound healing and reparative tissue processes. Clinical research suggests that this biomaterial promotes healing without causing excessive inflammation. Identifying potent homeostatic regulatory molecules in the PRF clot is crucial for limiting postoperative inflammation. In addition to platelet secretions, other blood constituents can release cytokines that can regulate inflammation.

description: The Cosmic Neutrino Background (C$ν$B) constitutes the last observable prediction of the standard cosmological model, which has yet to be detected directly. In this work, we show how the coherent scattering of neutrinos off dense neutron matter can lead to an additional cooling channel in neutron stars (NSs). We also include the effects of gravitational capture and boosting, but find that the cooling is efficient only in the presence of large overdensities. We further discuss the prediction of a boosted C$ν$B flux on Earth from nearby NSs and the potential detection prospects in the case of a future nearby galactic supernova. Although currently these ideas do not offer any detection prospects, they can be used to constrain overdensities $η\lesssim 10^{11}\textrm{-}10^{14}$ on short length scales $\mathcal{O}(10\text{ km})$. We also discuss the impact of new physics scenarios, such as long-range forces, on NS cooling through the C$ν$B.

description: Despite a shortage of Registered Dietitian Nutritionists (RDNs), only half of applicants currently match with a dietetic internship. A key reason is a shortage of preceptors. The purpose of this cross-sectional study was to better understand RDNs’ views of the preceptor role. An online survey was sent to a randomly selected sample of 10% of RDNs. A total of 1,170 RDNs completed the survey. The survey collected data on reasons dietitians precept, training received, and incentives. Five scales measured supports, benefits, satisfaction, commitment, and barriers to the preceptor role. Three groups of RDNs—current (37.1%), former (33.6%), and never preceptors (29.3%)—were compared and a regression analysis used to determine factors associated with precepting. The main reason RDNs precept was to help the field. Two-thirds of respondents would precept if it were their choice, yet only 37% were current preceptors. RDNs were somewhat dissatisfied with incentives. Continuing Professional Education Units (CPEUs) for precepting was the most common incentive (9.3%), while 35.6% received no incentives. The benefits scale mean scores were similar across the three groups, while current and former preceptors scored significantly higher (p < .001) than the never precepted group on the commitment, satisfaction, and support scales. The never group had significantly higher barriers (p < .001). The top barriers were increased stress from having interns, time-consuming/increased workload, and lack of incentives. Most (69%) RDNs received no preceptor training. Several factors were associated with being a current preceptor: fewer years as an RDN, Bachelor’s degree as the highest degree, holding a specialization credential, working full-time, working/residing in urban areas, working for a DI program, being on a DI advisory committee, and higher commitment scale scores. This study provides valuable insights for increasing RDNs who become preceptors, especially as the field transitions to the competency-based Future Education Model, which combines a graduate degree and supervised experiential learning. RDNs can be recruited as preceptors early in their career and encouraged to become members of advisory committees to connect them more to the preceptor role. Training for precepting can be widely provided, incentives improved, and barriers addressed to reduce stress for RDNs to precept.

Factors Affecting Probability Matching Behavior
Creators: Gao, Jie
Publisher: name: Columbia University
Year: 2013
Subjects: Cognitive psychology
Psychometrics

description: In life, people commonly face repeated decisions under risk or uncertainty. While normative economic models assume that people tend to make choices that maximize their expected utility, suboptimal behavior - in particular, probability matching - is frequently observed in research on repeated decisions. Probability matching is the tendency to match prediction probabilities of each outcome with the observed outcome probabilities in a random binary prediction task. For example, when people are faced with making with a sequence of predictions, such as repeatedly predicting the outcome of rolling a die with four sides colored green and two sides colored red, most people allocate about two-thirds of their predictions to green, and one-third to red. The optimal strategy, referred to as maximizing, would be to choose the outcome with the higher probability in every trial in the prediction task. Various causes for probability matching have been proposed during the past several decades. Here it is proposed that implicit adoption of a perfect prediction goal by decision makers might tend to elicit probability matching behavior. Thus, one factor that might affect the prevalence of probability matching behavior (investigated in Studies 1 and 2) is the type of performance goal. The manipulation in Study 1 contrasted single-trial prediction with prediction of four-trial sequences, which it is hypothesized might create an implicit perfect prediction goal for the sequence. In Study 2, three levels of goal were explicitly manipulated for each sequence: a perfect prediction goal, an 80% correct goal, and a 60% correct goal. In both studies it was predicted that more matching behavior would be observed for those who have a goal of perfect prediction than those who have a more reasonable (lower) goal. The results of both studies, conducted in an online worker marketplace, supported the goal-level hypothesis. The second factor proposed to affect the prevalence of probability matching is the type of conceptual schema describing the events to be predicted: independent events or complementary events. Study 3 investigated the effects of schema type and abstraction level of context on matching or maximizing behavior. Three abstraction levels of stories were included: abstract, concrete random devices, and real-world stories. The main hypothesis was that when the two options to be predicted are independent events, less matching and more maximizing behavior should be observed. Data from Study 3 supported the hypothesis that independent events tend to elicit more maximizing behavior. No effects of abstraction level were observed.

description: According to the logic of the offensive realism paradigm, the contemprary hegemon, the United States of America (US), ought to be coercing its junior allies to conform with the US security policies so that the US will retain its relative power in the international system. However, in dealing with the nuclear and conventional threats posed by the Democratic People's Republic of Korea (DPRK) from 1994 to 2004, the US has showed more accommodation than coercion towards its junior allies, Japan and the Republic of Korea(ROK). Why? To analyze this puzzling behaviour by the US, I make some adaptions to the realist conceptual framework called the 'alliance security dilemma', which was originally proposed by Michael Mandelbaum and later refined by Glenn Synder. In many cases, Synder's model has been used to focus on the fear of junior partners in an alliance that the majority power will either abandon them in their hour of need or entrap them in conflicts that are harmful to there national interests, or perhaps even do both. In this thesis I argue that the alliance security delemma also applies to the major alliance partner. The explanation for the US's accommodation of Japan and the ROK is that the US fears that the junior allies may partially abandon the alliance framework, and in doing so, reduce its hegemonic status. Although the US accommodation is best demonstrated during the 1993-94 nuclear crisis on the Korean Peninsula while the Clinton administration was in power, this trend continues during the current Bush administration. The findings of this thesis contribute to the literature on alliance politics by suggesting that security dilemma continues to play a key role in alliance maintenance.
What determines the X-ray intensity and duration of a solar flare?

description: Solar flares are observed and classified according to their intensity measured with the GOES X-ray Sensors. We show that the duration of a flare, as measured by the full width at half maximum (FWHM) in GOES is not related to the size of the flare as measured by GOES intensity. The durations of X-class flares range from a few minutes to a few hours, and the same is true of M- and C-class flares. In this work, we therefore examine the statistical relationships between the basic properties of flares -- temperature, emission measure, energy, etc. -- in comparison to both their size and duration. We find that the size of the flare is directly related to all of these basic properties, as previously found by many authors. The duration is not so clear. When examining the whole data set, the duration appears to be independent of all of these properties. In larger flares, however, there are direct correlations between the GOES FWHM and magnetic reconnection flux and ribbon area. We discuss the possible explanations, finding that this discrepancy may be due to large uncertainties in small flares, though we cannot rule out the possibility that the driving physical processes are different in smaller flares than larger ones. We discuss the implications of this result and how it relates to the magnetic reconnection process that releases energy in flares.

description: By using the results of a high-statistics (O(10^7) measurements) Monte Carlo simulation we test several predictions of perturbation theory on the O(n) non-linear sigma-model in 2 dimensions. We study the O(3) and O(8) models on large enough lattices to have a good control on finite-size effects. The magnetic susceptibility and three different definitions of the correlation length are measured. We check our results with large-n expansions as well as with standard formulae for asymptotic freedom up to 4 loops in the standard and effective schemes. For this purpose the weak coupling expansions of the energy up to 4 loops for the standard action and up to 3 loops for the Symanzik action are calculated. For the O(3) model we have used two different effective schemes and checked that they lead to compatible results. A great improvement in the results is obtained by using the effective scheme based on the energy at 3 and 4 loops. We find that the O(8) model follows very nicely (within few per mille) the perturbative predictions. For the O(3) model an acceptable agreement (within few per cent) is found.

title: Third Turn as a Teachable Moment in Foreign Language Pedagogy
Creators: name: Dashwood, Ann
Publisher: name: Griffith University
Year: 2005
Subjects: subject: Initial-response-evaluation
subject: foreign language pedagogy
subject: classroom dialogue

description: Talk is the vehicle of exchange in language classrooms when communicative competence is being developed. Turns of talk then facilitate the meaning-making process as students and teachers collaboratively come to understand the discourse of knowledge they are co-constructing. During the pivotal third turn in the essential teaching exchange, there is potential for teachers to realise productive pedagogies as they facilitate their students' organisational and pragmatic skills in the foreign language. This study brings a lens to Initiation-Response-Evaluation (IRE) triadic dialogue, which has been criticised for its monological overuse and limitation of students' language production. Analysis of the third turn shows the uptake to be an implicit move in the exchange. Teachers appear not to be aware of the potential benefit it offers them for co-constructed language use at that point in teacher-student interactions. Teachers draw on students' background knowledge and experiential learning in the four domains of productive pedagogies (intellectual quality, supportive classroom environment, recognition of difference and connectedness) when they engage them through an authentic use of language. For this study, potential for productive pedagogy was investigated in the classroom talk of two teachers of Japanese at year 10 level. In a case study, six transcribed and translated lessons were subjected to conversational and membership categorisation analyses using Bachman's (1990) communicative language ability framework to describe language production around the third turn and to hypothesise its effectiveness in providing opportunities for students to generate output in the target language.

description: Landslides inflict substantial societal and economic damage, underscoring their global significance as recurrent and destructive natural disasters. Recent landslides in northern parts of India and Nepal have caused significant disruption, damaging infrastructure and posing threats to local communities. Convolutional Neural Networks (CNNs), a type of deep learning technique, have shown remarkable success in image processing. Because of their sophisticated architectures, advanced CNN-based models perform better in landslide detection than conventional algorithms. The purpose of this work is to investigate CNNs' potential in more detail, with an emphasis on comparison of CNN based models for better landslide detection. We compared four traditional semantic segmentation models (U-Net, LinkNet, PSPNet, and FPN) and utilized the ResNet50 backbone encoder to implement them. Moreover, we have experimented with the hyperparameters such as learning rates, batch sizes, and regularization techniques to fine-tune the models. We have computed the confusion matrix for each model and used performance metrics including precision, recall and f1-score to evaluate and compare the deep learning models. According to the experimental results, LinkNet gave the best results among the four models having an Accuracy of 97.49% and a F1-score of 85.7% (with 84.49% precision, 87.07% recall). We have also presented a comprehensive comparison of all pixel-wise confusion matrix results and the time taken to train each model.

description: The Virasoro conjecture proposed by Eguchi-Hori-Xiong and S. Katz predicts that the generating function of Gromov-Witten invariants is annihilated by infinitely many differential operators which form a half branch of the Virasoro algebra. In this paper, we study the genus-1 case of the conjecture. In particular, we will give some necessary and sufficient conditions for the genus-1 Virasoro conjecture.
