title: Quantification of littoral wave action to establish the influence from wave energy converters (WEC)

description: No abstracts are to be cited without prior reference to the author.Wave energy converters have the potential to cause ecological change due to the attenuation of shoreline wave action. The widely accepted methods of estimating the amount of wave action or ”exposure” in the rocky shore littoral zone include establishing the locally most abundant biotopes, the use of nearshore wave models and cartographic fetch methods. Difficulties occur when subtle differences in the environmental variables have a significant influence on species, altering the community structure such that no single biotope is indicative of a given level of exposure to wave action at all geographical locations. The fractal nature of shoreline precludes the use of offshore measurements for determining energy levels at the scale of individual species. Fetch estimates do not account for oceanic swell, the main prerequisite for where a wave energy device will be installed. A new device is presented that is able to measure a quantitative level of wave action and its directional components. Measurements are determined by the mass loss of a polymer block, made from an inert material, and subject to an abrading mechanism which is directly related to the level of wave action experienced by the device. Long‐term monitoring data from Orkney are presented, showing good correlations of significant wave height and direction from concurrent wave buoy data. This new device will not only allow specific biotopes to be studied in relation to an objective measure of wave action over biologically meaningful time‐scales but could also be used for economical evaluations of nearshore wave energy resources.
Translating ‘optimally’: a proposal for the L2 class
Creators: name: Calfoglou, Christine
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2009
Subjects: Translation; Optimality; Re-ranking; Word order; Process errors

description: In this paper we discuss the function of translation in highlighting systematic L1 (Greek) vs L2 (English) similarities and differences in the L2 class. More specifically, we postulate a set of constraints operating on potential L2 translation outputs in the area of word order on a ranked basis, in the spirit of Optimality Theory (Prince & Smolensky 1993, 2004, Archangeli 1997, Kager 1999). Constraint ranking and re-ranking, we argue, is regulated by learner conformity to Prince & Smolensky’s (1993) ‘do only when necessary’ principle. Intermediate grammar learner outputs are thus allowed to surface while also being treated as a continuum.

Subjects: Modern Greek; Indicative mood; illocution; assertions; segmental marking

description: In this paper we investigate the illocutionary values of the Modern Greek Indicative mood. We discuss Indicative’s declarative uses, such as assertive, mirative, emphatic assertions uses and assertive uses in disguise (rhetoric questions). We also look at Indicative within an interrogative sentence type context and discuss polar interrogatives, content interrogatives and emphatic questions. We explore directive uses, such as hortatives. We further look at additional segmental marking, and refer in particular to requests for confirmation, mitigating questions, proffer and wondering uses of the Modern Greek Indicative.

description: The studies of multi-magnon excitations will extend our understandings of quantum magnetism and strongly correlated matters. Here, by using the time-evolving block decimation algorithm, we investigate the Bloch oscillations of two-magnon excitations under a gradient magnetic field. Through analyzing the symmetry of the Hamiltonian, we derive a rigorous and universal relation between ferromagnetic and anti-ferromagnetic systems. Under strong interactions, in addition to free-magnon Bloch oscillations, there appear fractional bounded-magnon Bloch oscillations which can be understood by an effective single-particle model. To extract the frequencies of Bloch oscillations and determine the gradient of magnetic field, we respectively calculate the fidelity in the time domain and the sub-standard deviation in the frequency domain. Our study not only explore the interaction-induced Bloch oscillations of multi-magnon excitations, but also provides an alternative approach to determine the gradient of magnetic field via ultracold atoms in optical lattices.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: No abstracts are to be cited without prior reference to the author.During the next decade there is likely to be an increase in tidal stream and wave power generation activity in Scottish waters. Concurrently, there will be the designation of additional offshore areas for seabird conservation. Experience from other marine industries suggests that these devices have the potential to affect seabird behaviour and habitat, leading to changes in rates of energy acquisition (e.g. through altering prey abundance) or expenditure (e.g. shifting the commuting distances by modifying spatial arrangement of prey patches). These changes to seabird energy budgets could affect rates of reproduction or survival, resulting in conflict between the renewable energy and conservation policies. Simulation modelling is one possible tool which could be used to predict how the alterations to bird behaviour and prey availability might affect seabird energy budgets and hence adult condition and chick growth rates. A behaviour‐based model is being constructed to estimate how a range of development scenarios could affect parent birds and their offspring. Individual units within the model include two interrelated adult birds and a chick. The behavioural state of each of the parents is based on the environment and their physiological condition. Preliminary results of the model will be presented, including important parameter estimates and sensitivity analyses.

description: No abstracts are to be cited without prior reference to the author.Management of coastal zones is currently in a new state of development. Until recently the planning of coastal activities was primarily based on single sectors. Now, multifunctional use of coastal space might be one of the strategies needed to overcome competing claims in coastal areas. For fisheries and aquaculture this means that combinations with other activities need to be developed. Currently the main focus is still on unrealized combinations of aquaculture and windmills. Now several combinations of fisheries, aquaculture, and other activities have been identified and the application possibilities have been described. The use of (ex) oil and gas rigs and other ocean energy infrastructures, along with existing aquaculture infrastructures, may lead to new approaches for multilevel coastal zone management.

description: No abstracts are to be cited without prior reference to the author.In order to reduce adverse effects of human activities on marine ecosystems, marine management is shifting towards an integrated multisector spatial planning approach. This requires large‐scale, high‐resolution data on fishing effort. We used vessel monitoring system (VMS) data from 2005-2006 to map gear‐specific fishing effort in and around the western English Channel (ICES areas VIIe–h), one of the most highly impacted marine ecosystems on the planet. Our maps highlight (i) the potential effects of fisheries closures around a proposed wave testing array station, Wave Hub, on the distribution of an international fishing fleet of large (>15 m length) vessels and (ii) spatial differences in the intensity of fishing by different gear types. Our VMS analyses show different gear types consistently have both spatially and temporally distinct effort patterns. In our case study, if proposed closures prevent use of all fishing gear then static gear users are likely to be the most affected due to the lower availability of their preferred fishing grounds and the high degree of patchiness of their effort. Active mobile gears show the highest effort intensity and widest distribution in the study area, hence impacts on benthic habitats and discarding are likely to have the most significant ecosystem effects in this area. We argue that the successful integration of fisheries management into marine spatial planning and ecosystem conservation requires highresolution gear‐specific effort data and show that the VMS is a valuable source of these data, if gear information is made available to fisheries managers and scientists.
Focusing devices in English and Greek

Subjects: English; Greek; information focus; contrastive focus; word order; focus movement; it-clefts

description: This paper investigates the realisation of focus in English and Greek. After providing a definition of focus and distinguishing between its two kinds, namely information and contrastive focus, I argue that, in both English and Greek, prosody accommodates information focus, while both syntax and prosody are responsible for contrastive focus. There is, however, an important difference in the syntactic device employed for the realisation of contrastive focus in each language. In Greek contrastive focus is realised via movement to [Spec, FocP], while English has to take recourse to it-clefts. An explanation is offered for this dissimilarity on the basis of the typological difference that exists between English and Greek.

Focus on Clefts: A Perspective from Cypriot Greek
Creators: name: Grohmann, Kleanthes K.
Publisher: name: Selected papers on theoretical and applied linguistics

Subjects: clefting; focus; (Cypriot) Greek; predication; sideward movement

description: Cypriot Greek (CG) differs from Standard Modern Greek (SMG) in many interesting ways, even in the realm of grammar (morphosyntax). This paper investigates one such difference, namely the syntax of focus. It is argued that CG focus constructions exhibit an underlying clefting structure. This is put into perspective with both SMG (which lacks clefts altogether) and English (in particular, it-clefts). A novel analysis is proposed for the derivation of clefting structures — at least for English-like it-clefts and CG focus clefts: CG focused expressions are sideward moved into an underlying predicational cleft structure, analogously to English it-clefts as argued.

description: This paper proposes a framework for analysing stance in argumentative essays written by Greek advanced learners of English. The essays are included in the Greek Corpus of Learner English (GRICLE). Their analysis showed that Greek learners point to their attitude mainly by using lexical chunks such as it is true that, it is a fact that, it is obvious that. Using such chunks allows students to defer commitment to the stated proposition, thereby presenting it as a commonly accepted fact. This technique is considered to be culturally induced as it is a typical rhetorical convention commonly followed in L1 writing.

description: A análise da saúde vocal é fundamental para a avaliação de distúrbios relacionados à voz. Os métodos comumente utilizados para a detecção desses distúrbios geralmente são invasivos, causam desconforto ao paciente, possuem custo elevado, necessitam de local especializado e não garantem a detecção imediata do problema, sendo necessária a avaliação contínua do paciente. Diante do exposto, este trabalho propõe um sistema embarcado, de baixo custo, capaz de realizar a aquisição e análise de dados referentes a vibração das pregas vocais, através do sensor de vibração piezoelétrico. O sensor utilizado, teve seu sinal condicionado com a finalidade de permitir a coleta de dados pelo micro controlador ESP32. O sistema implementado mostrou-se eficaz como ferramenta de apoio ao monitoramento da saúde vocal do locutor, com a detecção das medidas de frequência fundamental, jitter e shimmer.

description: Emerging evidence suggests that microRNAs (miRNAs) serve an important role in tumourigenesis and development. Although the low expression of miR-125a-5p in non-small-cell lung cancer (NSCLC) has been reported, the underlying mechanism remains unknown. In the current study, the low expression of miR-125a-5p in NSCLC was verified in paired cancer tissues and adjacent non-tumour tissues. Furthermore, the CpG island in the miR-125a-5p region were hypermethylated in the tumour tissues. And the hypermethylation was negatively correlated with the miR-125a-5p expression. Target gene screening showed that the histone methyltransferase Suv39H1 was one of the potential target genes. In vitro studies showed that miR-125a-5p could directly suppress the Suv39H1 expression and decrease the H3K9me3 levels. On the other hand, the Suv39H1 could induce demethylation of miR-125a-5p, resulting in re-activation of miR-125a-5p. What is more, overexpessing miR-125a-5p could also self-activate the silenced miR-125a-5p in NSCLC cells, which suppressed cell migration, invasion and proliferation in vitro and inhibited cancer progression in vivo. Thus, we uncovered here that the epigenetic silenced miR-125a-5p could be self-activated through targeting Suv39H1 in NSCLC, suggesting that miR-125a-5p might not only have the potential prognostic value as a tumour biomarker but also be potential therapeutic targets in NSCLC.

description: We study the problem of whether the active gravitational mass of an isolated system is equal to the total energy in the tetrad theory of gravitation. The superpotential is derived using the gravitational Lagrangian which is invariant under parity operation, and applied to an exact spherically symmetric solution. Its associated energy is found equal to the gravitational mass. The field equation in vacuum is also solved at far distances under the assumption of spherical symmetry. Using the most general expression for parallel vector fields with spherical symmetry, we find that the equality between the gravitational mass and the energy is always true if the parameters of the theory $a_1$, $a_2$ and $a_3$ satisfy the condition, $(a_1+ a_2) (a_1-4a_3/9)\neq0$. In the two special cases where either $(a_1+a_2)$ or $(a_1-4a_3/9)$ is vanishing, however, this equality is not satisfied for the solutions when some components of the parallel vector fields tend to zero as $1/\sqrt{r}$ for large $r$.

description: The problem of finding thermally minimizing configurations of a humanoid robot to recover its actuators from unsafe thermal states is addressed. A first-order, data-driven, effort-based, thermal model of the robot's actuators is devised, which is used to predict future thermal states. Given this predictive capability, a map between configurations and future temperatures is formulated to find what configurations, subject to valid contact constraints, can be taken now to minimize future thermal states. Effectively, this approach is a realization of a contact-constrained thermal inverse-kinematics (IK) process. Experimental validation of the proposed approach is performed on the NASA Valkyrie robot hardware.

description: The rust programming language is one of the fastest-growing programming languages, thanks to its unique blend of high performance execution and memory safety. Still, programs implemented in rust can contain critical bugs. Apart from logic bugs and crashes, code in unsafe blocks can still trigger memory corruptions. To find these, the community uses traditional fuzzers like libfuzzer or aflpp, in combination with rust-specific macros. Of course, the fuzzers themselves are still written in memory-unsafe languages.

In this paper, we explore the possibility of replacing the input generators with rust, while staying compatible to existing harnesses. Based on the rust fuzzer library libafl, we develop ourtool, a drop-in replacement for the C++ component of cargo-fuzz. We evaluate our tool, written in rust, against the original fuzzer libfuzzer. We show that we are not only able to successfully fuzz all three targets we tested with ourtool, but outperform cargo-fuzz in bug coverage. During our preliminary evaluation, we already manage to uncover new bugs in the pdf crate that could not be found by cargo-fuzz, proving the real-world applicability of our approach, and giving us high hopes for the planned follow-up evaluations.

description: I give an introductory review of recent, fascinating developments in supersymmetric gauge theories. I explain pedagogically the miraculous properties of supersymmetric gauge dynamics allowing one to obtain exact solutions in many instances. Various dynamical regimes emerging in supersymmetric Quantum Chromodynamics and its generalizations are discussed. I emphasize those features that have a chance of survival in QCD and those which are drastically different in supersymmetric and non-supersymmetric gauge theories. Unlike most of the recent reviews focusing almost entirely on the progress in extended supersymmetries (the Seiberg-Witten solution of N=2 models), these lectures are mainly devoted to N=1 theories. The primary task is extracting lessons for non-supersymmetric theories.

description: Detailed information on the electronic states of both V and Mn 3d electrons in the ferrimagnet Mn2VAl is obtained by the bulk sensitive resonant inelastic soft x-ray scattering (SX-RIXS) excited with the circularly polarized light under an external magnetic field for the first time. The results under the V L-edge excitation have revealed the negligible partial density of states (PDOS) of the V 3d states around the Fermi energy as well as their rather localized character. Under the Mn L-edge excitation, on the other hand, the spectra are dominated by fluorescence with clear magnetic circular dichroism with noticeable excitation photon energy dependence. Compared with the theoretical prediction of the RIXS spectra based on the density-functional-theory band structure calculation, an itinerant, spin-dependent character of the Mn 3d states and decays of the Mn 2p core states are confirmed in consistence with the half-metallicity of the Mn 3d states.

description: This paper describes an abstract machine for linguistic formalisms that are based on typed feature structures, such as HPSG. The core design of the abstract machine is given in detail, including the compilation process from a high-level language to the abstract machine language and the implementation of the abstract instructions. The machine's engine supports the unification of typed, possibly cyclic, feature structures. A separate module deals with control structures and instructions to accommodate parsing for phrase structure grammars. We treat the linguistic formalism as a high-level declarative programming language, applying methods that were proved useful in computer science to the study of natural languages: a grammar specified using the formalism is endowed with an operational semantics.

The number fluctuations in each spin component change rapidly from being enormous (order $N$) to exceedingly small (order 1) as the magnetization of the system increases. A fragmented condensate can be turned into a single condensate state by magnetic field gradients. The conditions for existence and the method of detecting fragmented states are presented.

description: We introduce a new estimator for the mean pairwise velocities of galaxy clusters, which is based on the measurement of the clusters' $\textit{transverse}$ velocity components. The Rees-Sciama (RS) effect offers an opportunity to measure transverse peculiar velocities through its distinct dipolar signature around the halo centers in the Cosmic Microwave Background (CMB) temperature map. We exploit this dipolar structure to extract the magnitude and direction of the transverse velocity vectors from CMB maps simulated with the expected characteristics of future surveys like CMB-S4. Although in the presence of lensed CMB and instrumental noise individual velocities are not reliably reconstructed, we demonstrate that the mean pairwise velocity measurement obtained using the estimator yields a signal-to-noise ratio of $5.2$ for $\sim21,000$ halos with $M > 7\times10^{13}\rm M_\odot$ in a $40\times40$ [deg$^2$] patch at $z=0.5$. While the proposed estimator carries promising prospects for measuring pairwise velocities through the RS effect in CMB stage IV experiments, its applications extend to any other potential probe of transverse velocities.

description:  In the last 20-30 years, interest in antioxidant substances, especially natural synthesis, has increased. Also, a deeper study of vitamins better reveals the biochemical and physiological aspects of the life of the cell and the extracellular matrix. Progress in science creates new flagogens that the human body has not encountered before. This leads to an increase in allergic reactions and chronic inflammation. Chronic inflammation itself can serve as a good breeding ground for the formation of tumors. Vitamin E analyzed in this work has a strong antioxidant effect [1], anti-inflammatory effect [2], and antitumor effect [3]. Given such important properties of tocopherols and tocotrienols, it would be correct to say that a medical professional should have an idea of what foods to find natural vitamin E in, what it is for, and what diseases can be prevented using supplements containing vitamin E.

description: A new technique is presented which enables the fabrication of highly transparent Josephson junctions in combination with mesoscopic devices. We utilize a modified AFM tip to plough grooves into superconducting material, thus defining a weak link. This weak link is made within the superconducting split-gates, which are used to electrostatically form a conventional quantum dot and serves as a source of millimeter wave radiation around 100 GHz. We show the characteristics of typical junctions built and discuss their high-frequency properties. We find that the millimeter wave emission of the weak link leads to a bolometric effect in the case of quantum point contact spectroscopy.

description: Emerging evidence suggests that microRNAs (miRNAs) serve an important role in tumourigenesis and development. Although the low expression of miR-125a-5p in non-small-cell lung cancer (NSCLC) has been reported, the underlying mechanism remains unknown. In the current study, the low expression of miR-125a-5p in NSCLC was verified in paired cancer tissues and adjacent non-tumour tissues. Furthermore, the CpG island in the miR-125a-5p region were hypermethylated in the tumour tissues. And the hypermethylation was negatively correlated with the miR-125a-5p expression. Target gene screening showed that the histone methyltransferase Suv39H1 was one of the potential target genes. In vitro studies showed that miR-125a-5p could directly suppress the Suv39H1 expression and decrease the H3K9me3 levels. On the other hand, the Suv39H1 could induce demethylation of miR-125a-5p, resulting in re-activation of miR-125a-5p. What is more, overexpessing miR-125a-5p could also self-activate the silenced miR-125a-5p in NSCLC cells, which suppressed cell migration, invasion and proliferation in vitro and inhibited cancer progression in vivo. Thus, we uncovered here that the epigenetic silenced miR-125a-5p could be self-activated through targeting Suv39H1 in NSCLC, suggesting that miR-125a-5p might not only have the potential prognostic value as a tumour biomarker but also be potential therapeutic targets in NSCLC.

description: The shape of a liquid surface bounded by an acute or obtuse planar angular sector is considered by using classical analysis methods. For acute angular sectors the two principal curvatures are of the order of the (fixed) mean curvature. But for obtuse sectors, the principal curvatures both diverge as the vertex is approached. The power-law divergence becomes stronger with increasing opening angle. Possible implications of this contrasting behavior are suggested.

description: As energy demand grows at a faster rate in developing regions, energy security and environmental sustainability become issues of concern. The transition from traditional fuels to modern forms of energy requires huge infrastructure development and poses greater financial risk at the same time. In this study, we analyse the long-term electricity sector expansion of one of the fastest developing regions of the world, Bangladesh using a dynamic multi-sector energy economic model. We also evaluate the interrelation between energy consumption and environmental emission by imposing emission limits. The social implications and optimal power generation mix for different policy scenarios have been investigated.

description: Motivated by the recent experimental observation of the half-quantized thermal Hall conductivity for the candidate material of the Kitaev spin liquid, $α$-RuCl$_3$[ Y. Kasahara et al., Nature 559, 227 (2018)], we investigate effects of non-Kitaev exchange interactions, which exist in the real material, on the gapped chiral spin liquid state realized in the case with an applied magnetic field. It is found that off-diagonal exchange interactions enhance significantly the mass gap of Majorana fermions. This result provides a possible explanation for robust quantization of the thermal Hall conductivity observed in the above-mentioned experiment. Furthermore, we demonstrate that if the Kitaev spin liquid state and the zigzag antiferromagnetic order coexist around the border of these two phases, off-diagonal exchange interactions can induce Fermi surfaces of Majorana fermions, leading to a state similar to the U(1) spin liquid.

description: NGC 6558 is a bulge globular cluster with a blue horizontal branch (BHB), combined with a metallicity of [Fe/H]~-1.0. It is similar to HP 1 and NGC 6522, which could be among the oldest objects in the Galaxy. Element abundances in these clusters could reveal the nature of the first supernovae. We aim to carry out detailed spectroscopic analysis for four red giants of NGC 6558, in order to derive the abundances of the light elements C, N, O, Na, Al, the alpha-elements Mg, Si, Ca, Ti, and the heavy elements Y, Ba, and Eu. High-resolution spectra of four stars with FLAMES-UVES@VLT UT2-Kueyen were analysed. Spectroscopic parameter-derivation was based on excitation and ionization equilibrium of FeI and FeII. This analysis results in a metallicity of [Fe/H] = -1.17+-0.10 for NGC 6558. We find the expected alpha-element enhancements in O and Mg with [O/Fe]=+0.40, [Mg/Fe]=+0.33, and low enhancements in Si and Ca. Ti has a moderate enhancement of [Ti/Fe]=+0.22. The r-element Eu appears very enhanced with a mean value of [Eu/Fe]=+0.63. Ba appears to have a solar abundance ratio relative to Fe. NGC 6558 shows an abundance pattern that could be typical of the oldest inner bulge globular clusters, together with the pattern in the similar clusters NGC 6522 and HP 1. They show low abundances of the odd-Z elements Na and Al, and of the explosive nucleosynthesis alpha-elements Si, Ca, and Ti. The hydrostatic burning alpha-elements O and Mg are normally enhanced as expected in old stars enriched with yields from core-collapse supernovae, and the iron-peak elements Mn, Cu, Zn show low abundances, which is expected for Mn and Cu, but not for Zn. Finally, the cluster trio NGC 6558, NGC 6522, and HP 1 show similar abundance patterns.

description: This study develops an online predictive optimization framework for dynamically operating a transit service in an area of crowd movements. The proposed framework integrates demand prediction and supply optimization to periodically redesign the service routes based on recently observed demand. To predict demand for the service, we use Quantile Regression to estimate the marginal distribution of movement counts between each pair of serviced locations. The framework then combines these marginals into a joint demand distribution by constructing a Gaussian copula, which captures the structure of correlation between the marginals. For supply optimization, we devise a linear programming model, which simultaneously determines the route structure and the service frequency according to the predicted demand. Importantly, our framework both preserves the uncertainty structure of future demand and leverages this for robust route optimization, while keeping both components decoupled. We evaluate our framework using a real-world case study of autonomous mobility in a university campus in Denmark. The results show that our framework often obtains the ground truth optimal solution, and can outperform conventional methods for route optimization, which do not leverage full predictive distributions.

Edge wave and boundary layer of vortex matter

description: We show that a vortex matter, that is a dense assembly of vortices in an incompressible two-dimensional flow, such as a fast rotating superfluid or turbulent flows with sign-like eddies, exhibits (i) a boundary layer of vorticity (vorticity layer), and (ii) a nonlinear wave localized within the vorticity layer, the edge wave. Both are solely an effect of the topological nature of vortices. Both are lost if the vortex matter is approximated as a continuous vorticity patch. The edge wave is governed by the integrable Benjamin-Davis-Ono equation exhibiting solitons with a quantized total vorticity. Quantized solitons reveal the topological nature of the vortices through their dynamics. The edge wave and the vorticity layer are due to odd viscosity of the vortex matter. We also identify the dynamics with the action of the Virasoro-Bott group of diffeomorphisms of the circle, where odd viscosity parametrizes the central extension. Our edge wave is a hydrodynamic analog of the edge states of the fractional quantum Hall effect.

description: A spin-wave theory of short-range order in the square lattice Heisenberg antiferromagnet is formulated. With growing temperature from T=0 a gapless mode is shown to arise simultaneously with opening a gap in the conventional spin-wave mode. The spectral intensity is redistributed from the latter mode to the former. For low temperatures the theory reproduces results of the modified spin-wave theory by M.Takahashi, J.E.Hirsch et al. and without fitting parameters gives values of observables in good agreement with Monte Carlo results in the temperature range 0 <= T < 0.8J where J is the exchange constant.
