description: The aim of this article is to identify a set of efficiency drivers which can explain differences in revenue efficiency between dairy farms. To explore farm efficiency, we apply stochastic frontier analysis on a balanced panel of 212 Norwegian dairy farms. The results show that on average the farms can increase the revenue from dairy by 28 percentage points. The article identifies important drivers of revenue efficiency which the farmer can change in the short or medium run to increase efficiency. Automatic milking systems, high beef production per cow, low age at first calving and organic farming are among drivers which can explain differences in revenue efficiency between farms. Our findings have implications for both management scholars, practitioners and policy makers.

description: The nn final state interaction has been investigated in d+2H->(pp)S+(nn)S->p+p+n+n reaction going through a formation and breakup of singlet diproton and dineutron in the intermediate state. In the kinematically complete experiment performed at Ed =15 MeV two proton and neutron were detected at angles close to those of emission of (pp)S and (nn)S systems. Simulation of the reaction showed that the shape of neutron energy (timing) spectrum depends on epsnn - the energy of virtual 1S0 state of nn-system. The most likely value epsnn = 0.076 +/- 0.006 MeV was obtained by fitting procedure using the experimental data and simulations. This low value of epsnn evidently indicates on effective enhancement of nn-interaction in the intermediate state of studied reaction

description: The interest in the utilization of bio fillers in thermoplastics has increased recently, mainly due to the need in overcoming the environmental problems caused by the agricultural by products. Based on former exploratory research, we used seaweed fiber as a novel bio filler for the production of polypropylene (PP) biocomposites. Maleic anhydride grafted PP was applied as compatibilizers. The incorporation of the bio fillers at compositions ranging from 10-30% was carried out by melt compounding in extruder and then injection moulded into standard test samples. Mechanical and physical characteristics of the composite systems were studied to evaluate the effect of seaweeds content on PP. It has been found that while there is a decrease in elasticity modulus, tensile strength at break and elongation etc., the hardness and melt flow index were found to be increased with the seaweed content.

description: $ω$ Centauri (NGC 5139) hosts hundreds of pulsating variable stars of different types, thus representing a treasure trove for studies of their corresponding period-luminosity (PL) relations. Our goal in this study is to obtain the PL relations for RR Lyrae, and SX Phoenicis stars in the field of the cluster, based on high-quality, well-sampled light curves in the near-infrared (IR). $ω$ Centauri was observed using VIRCAM mounted on VISTA. A total of 42 epochs in $J$ and 100 epochs in $K_{\rm S}$ were obtained, spanning 352 days. Point-spread function photometry was performed using DoPhot and DAOPHOT in the outer and inner regions of the cluster, respectively. Based on the comprehensive catalogue of near-IR light curves thus secured, PL relations were obtained for the different types of pulsators in the cluster, both in the $J$ and $K_{\rm S}$ bands. This includes the first PL relations in the near-IR for fundamental-mode SX Phoenicis stars. The near-IR magnitudes and periods of Type II Cepheids and RR Lyrae stars were used to derive an updated true distance modulus to the cluster, with a resulting value of $(m-M)_0 = 13.708 \pm 0.035 \pm 0.10$ mag, where the error bars correspond to the adopted statistical and systematic errors, respectively. Adding the errors in quadrature, this is equivalent to a heliocentric distance of $5.52\pm 0.27$ kpc.

description: Rapid transformations in the polar regions due to global warming are leading to temperatures far above the global average, severely impacting ecosystems, especially freshwater systems. Understanding these changes is crucial as they threaten vital ecosystem services essential for human and environmental well-being and key to One-Health approaches. Shifting precipitation patterns, ice melt, and permafrost thaw alter freshwater availability, posing challenges to local communities and increasing their vulnerability. Climate warming also deteriorates water quality through the release of pollutants and harmful microorganisms, endangering both human and natural health. Arctic communities face additional adaptation economic challenges. Urgent action through evidence-based practices, scientific research, policy-making, and local involvement is necessary to protect freshwater resources for a sustainable future.

Whitin this context, the COLDwater initiative crystallised into a white paper elaborated by a team of 20 experts from 14 European institutions who convened for a 3-day workshop in November 2023 to discuss the challenges confronting polar freshwater resources.

International collaboration is paramount in understanding freshwater dynamics in the Arctic and Antarctic. Initiatives focusing on transboundary water resources underscore the importance of collaboration across institutions and nations to collectively advance polar ecosystem knowledge. Such collaboration not only benefits polar regions but also aligns with the UN Sustainable Development Goals. Therefore, funding mechanisms should prioritize bridging the gap between knowledge and action and supporting international cooperation in research agendas.

description: The de Finetti theorem and its extensions concern the structure of multipartite probability distributions with certain symmetry properties, the paradigmatic original example being permutation symmetry. These theorems assert that such symmetric distributions are well approximated by convex combinations of uncorrelated ones. In this article, we apply de Finetti theorems to quantum gravity theories, such as the Sachdev-Ye-Kitaev (SYK) model or large-N vector and gauge theories. For SYK we put recent studies of information/entanglement dynamics in a general and rigorous basis. For vector and gauge theories, we find a gauge invariant operator whose expectation value provides the leading term in the entanglement entropy in all states close enough to a given classical state. These results can be unified through a generic statement about the nature of Schmidt decompositions and decoherence in large-N theories. In the reverse direction, we extend de Finetti theorems in various ways and provide an independent approach to the theorems only based on the large-N properties of the gauge invariant coherence group.

Second Order QED Processes in an Intense Electromagnetic Field

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Some non linear, second order QED processes in the presence of intense plane electromagnetic waves are investigated. Analytic expressions with general kinematics are derived for Compton scattering and $e^+e^-$ pair production in a circularly polarised external electromagnetic field. The differential cross sections were investigated numerically for photon energies up to 50 MeV, external field intensity parameter $ν^2$ to value 2, and all scattering angles. The variation of full cross sections with respect to external field intensity was also established. The presence of the external field led to resonances in the Compton scattering and pair production differential cross sections. These resonances were investigated by calculating the electron self energy in the presence of the external field. At resonance the differential cross sections were enhanced by several orders of magnitude. The resonances occurred for values of external field intensity parameter $ν^2 <1$, lowering the limit of $ν^2 \sim 1$ at which point non linear effects in first order external field QED processes become important. Generally, full cross sections increased with increasing external field intensity, though peaking sharply for Compton scattering and levelling off for pair production. An application was made to non linear background studies at $e^+e^-$ linear colliders. The pair production process and electron self energy were studied for the case of a constant crossed electromagnetic field. It was found that previous analytic expressions required the external field to be azimuthally symmetric. New analytic expressions for the more general non azimuthally symmetric case were developed and a numerical parameter range equivalent to that proposed for future linear collider designs was considered.

description: Mid-IR colour selection techniques have proved to be very efficient in finding AGN. This is because the AGN heats the surrounding dust producing warm mid-IR colours. Using the WISE 3.6, 4.5 and 12 $μm$ colours, the largest sample of IR selected AGN has already been produced containing 1.4 million AGN over the whole sky. Here, we explore the X-ray properties of this AGN sample by cross-correlating it with the subsample of the 3XMM X-ray catalogue that has available X-ray spectra and at the same time optical spectroscopy from SDSS. Our goal is to find rare luminous obscured AGN. Our final sample contains 65 QSOs with $\rm{log}\,νL_ν\ge 46.2$\,erg\,s$^{-1}$. This IR luminosity cut corresponds to $\rm{log}\,L_X \approx 45$\,erg\,s$^{-1}$, at the median redshift of our sample ($z=2.3$), that lies at the bright end of the X-ray luminosity function at $z>2$. The X-ray spectroscopic analysis reveals seven obscured AGN having a column density $\rm N_H>10^{22} cm^{-2}$. Six of them show evidence for broad [CIV] absorption lines and five are classified as BALQSOs. We fit the optical spectra of our X-ray absorbed sources to estimate the optical reddening. We find that none of these show any obscuration according to the optical continuum. These sources add to the growing evidence for populations of luminous QSOs with evidence for substantial absorption by outflowing ionised material, similar to those expected to be emerging from their absorbing cocoons in the framework of AGN/galaxy co-evolution.

description: The generality of the processes of crystal growth from the vapor phase on substrate and from the amorphous state in films is that in both cases a disorder-order transition takes place. This predetermines the structural and morphological analogy between the main forms of crystal growth on substrates and the main types of crystallization of amorphous films. Based on the analysis of the structure and morphology of crystals growing in amorphous films at electron beam influence, a quantitative interpretation of layer polymorphous crystallization (analog of Frank-van der Merwe growth mode), island polymorphous crystallization (analog of Volmer–Weber growth mode) and dendrite polymorphous crystallization (analog of Stranski–Krastanov growth mode) where given. For each crystallization mode the parameter of dimensionless relative length δ0, equal to the ratio of the characteristic length to the value, characterizing the size of the unit cell of the crystal, were assigned and crystallization curves were built.

description: During reinforcing steel rolling such geometric defect as the absence of longitudinal or transverse ribs is spread. For a detailed study of the process of reinforcement profile rolling and its further optimization, computer simulation in the software complex DEFORM-3D was carried out. In the previous works the most rational, from the authors' point of view, forms of pre - finishing gauges for rolling of reinforcing steel are proposed - a one-radius oval and a flat oval with double concavity. Also, a new calibration for rolling of round and reinforcing steel was proposed, the main feature of which is the pre-finishing caliber, made in the form of a smooth barrel. To assess the impact of the pre-form gauge on the strain state, a single simulation was conducted, i.e. modeling only the prefinishing caliber, after which the calculation of the finishing pass was conducted. From considered calibers, the most uniform distribution of deformation provides a flat oval with double concavity, where the distribution in the vertical and horizontal directions is approximately the same. In other two calibers, the spread difference is quite different. After rolling in the finishing pass, the metal completely filled the contour of the caliber, as well as the screw incisions of the transverse ribs. The longitudinal ribs are also fully formed. All geometric parameters with tolerances fully comply with the requirements of GOST 10884-94.

description: The tolerance analysis for flexible parts and assemblies is the precious step in manufacturing parts in industry. In order to minimize the cost of the process, the literature has focused on reviewing tolerance analysis for flexible parts and assemblies. In this paper, are developed two major methods of tolerance analysis for flexible assemblies. Furthermore, to improve the performance of the proposed model that has been simulated to predict the deformation of flexible parts and assemblies, we have taken into account the spot-welding effects. Finally, through a comparative study, the results prove the performances of the proposed approach.

description: We calculate the rho meson mass in a weak magnetic field using effective $ρππ$ interaction. It is seen that both $ρ^0$ and $ρ^\pm$ masses decrease with the magnetic field in vacuum. $ρ$ meson dispersion relation has been calculated and shown to be different for $ρ^0$ and $ρ^\pm$. We also calculate the $ρππ$ decay width and spectral functions of $ρ^0$ and $ρ^\pm$. The width is seen to decrease with $eB$ and the spectral functions become narrower.

description: The PIEZO protein family was first described in animals where these mechanosensitive calcium channels perform numerous essential functions, including the perception of light touch, shear, and compressive forces. PIEZO homologs are present in most eukaryotic lineages and recently we reported that two PIEZO homologs from moss Physcomitrium patens localize to the vacuolar membrane and modulate its morphology in tip-growing caulonemal cells. Here we show that predicted structures of both PpPIEZO1 and PpPIEZO2 are very similar to that of mouse Piezo2. Furthermore, we show that both moss PIEZO genes are ubiquitously expressed in moss vegetative tissues and that they are not required for normal vacuolar pH or intracellular osmotic potential. These results suggest that moss PIEZO proteins are widely expressed mechanosensory calcium channels that serve a signaling rather than maintenance role in vacuoles.

description: This paper describes the sintering of an injection molded 420 martensitic stainless steel with additions of niobium, with the aim of producing high mechanical properties. And at the same time, microstructural and mechanical characterization of these produced parts was also carried out. At the initial stage, 420 martensitic stainless-steel powders were mixed with a multi-component binder system for preparing feedstock. Then the prepared feedstock was granulated and shaped by injection molding. And then, the shaped samples were subjected to the debinding process. These samples were sintered at different temperatures for various times. Samples sintered under the condition that gave way to the highest relative density were heat treated. Sintered and heat-treated samples were separately subjected to microstructural and mechanical characterization. All analysis showed that using polymeric binder system led to plentiful martensite ratio and carbide precipitates to be occurred in the injection molded samples. Mechanical characterization was performed by hardness measurements and tensile tests.

description: The cross section of the process $e^+e^-\toπ^+π^-$ has been measured in the center of mass energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider VEPP-2000. The measurement is based on a full dataset collected below 1 GeV during three data taking seasons, corresponding to an integrated luminosity of about 62 pb$^{-1}$. In the dominant $ρ$-resonance region, a systematic uncertainty of 0.7% has been reached. At energies around $ϕ$-resonance the $π^+π^-$ production cross section was measured for the first time with high beam energy resolution. The forward-backward charge asymmetry in the $π^+π^-$ production has also been measured. It shows a strong deviation from the theoretical prediction based on the conventional scalar quantum electrodynamics framework, and it is in good agreement with the generalized vector-meson-dominance and dispersive-based predictions. The impact of the presented results on the evaluation of the hadronic contribution to the anomalous magnetic moment of muon is discussed.

description: The results are based on DFT calculations of hydroxyapatite (HAP) structures, pristine and defective, determined by various defects formed by Oxygen vacancy dependent on its charged states. Ordered hexagonal and monoclinic HAP phases have own spontaneous polarization, while disordered do not have it. These ferroelectric properties determined by orientation of OH dipoles provide piezoelectric and pyroelectric phenomena in such HAP structures for which all corresponding values and coefficients were investigated and calculated in this paper. The optical properties of defective HAP are mainly determined by various types of Oxygen vacancy defects (as well as hydroxyl OH group vacancy) and can lead to absorption and photocatalysis under ultraviolet illumination. The hybrid density functional theory (DFT) approaches of the structural and electronic properties of oxygen vacancies in large HAP supercells within the plane-wave formalism were mainly used in this work. The vacancies were investigated in large supercells, for which formation energies and electronic transition energies were calculated. The calculations were carried out using DFT, as implemented by the (Vienna ab initio package) VASP. The exchange-correlation potential was evaluated either using the generalized gradient approximation according to PBE functional or the threeparameter hybrid B3LYP functional, which incorporates a fraction of exact exchange with local and semi-local functional. These methods are also applied to the calculation of defect levels. Several other methods, such as AIMPRO and HyperChem, were used too, for several necessary cases and comparison. As a result, the main new features of pristine and defective HAP were established and analysed from first-principles.

description: Elevated CO2 (eCO2; 1000 ppm) influences developing rice leaf formation, reducing leaf blade length and width as compared to rice grown under ambient CO2 (aCO2; 400 ppm). Since micro RNAs (miRNAs) are known to play multiple roles in plant development, we hypothesized that miRNAs might be involved in modulating leaf size under eCO2 conditions. To identify miRNAs responding to eCO2, we profiled miRNA levels in developing rice leaves (P4; plastochron number of the fourth-youngest leaf) under eCO2 using small RNA-seq. We detected 18 mature miRNA sequences for which expression levels varied more than two-fold between the eCO2 and aCO2 conditions. Among them, only miR396e and miR396f significantly differed between the two conditions. Additionally, the expression of growth-regulating factors (GRFs), potential target mRNA of miR396s, were repressed under the eCO2 condition. We used an antisense oligonucleotide approach to confirm that single-strand DNA corresponding to the miR396e sequence effectively downregulated GRF expression in developing leaves, reducing the leaf blade length, such as for rice grown under eCO2. These results suggest that the miR396–GRF module is crucially relevant to controlling rice leaf blade length in eCO2 environments.

description: Quantum nondemolition theory has been well understood for a number of decades, however, applications of such techniques remain limited owing to the increased complexity that these techniques require. In this paper, quantum nondemolition theory is used to investigate the performance of a real world device, an electro-optic feed-forward intensity noise eater. It is shown that by replacing the typical beamsplitter in such a device with a single pass second harmonic generation followed by a dichroic mirror the performance of the noise eater can be significantly improved, even with low conversion efficiencies.

description: An endophytic Pseudomonas fluorescens (BsEB-1) was obtained from the roots of Bletilla striata. We investigated its growth-promoting properties and observed the impact of its inoculation on both the growth and polysaccharide content of Bletilla striata tubers. It was found that BsEB-1 possessed three growth-promoting activities: phosphate-solubilizing, produced indoleacetic acid (IAA) and siderophores, but had no nitrogen-fixing activity. BsEB-1 could rapidly attach to the root hairs of Bletilla striata tissue culture seedlings and endophytically colonize the region of maturation in the roots. It also significantly promoted the rooting and transplant survival rate of the seedlings, as well as the growth and expansion of the tubers, but did not increase their polysaccharide content. Pseudomonas fluorescens BsEB-1 exhibits potential for applications in the artificial planting of Bletilla striata.

description: Purpose of the study: We investigated the outcomes and outcome predictors of depressive and anxiety disorders in a general population sample of young adults with a lifetime history of these disorders. Materials and methods: The study sample was derived from a nationally representative two-stage cluster sample of Finns aged 19–34 years. The original study was carried out in 2003–2005, and the follow-up in 2011. We investigated participants diagnosed with a depressive or anxiety disorder based on a SCID interview (excluding those with only a single specific phobia) (DAX-group, N = 181). The control group included those with no DSM-IV- diagnosis (N = 290). They were followed up with the M-CIDI interview assessing 12-month depressive and anxiety disorders in 2011. Results: In 2011, 22.8% of the DAX-group was diagnosed with a depressive or anxiety disorder compared to 9.8% of the control group. Education was lower and quality of life worse in the DAX-group than in the control group. Those participants of the DAX-group who received a diagnosis in 2011 had poorer quality of life than those in remission, which emphasizes the influence of a current disorder on the quality of life. Higher score in the Mood Disorder Questionnaire (MDQ) at baseline predicted poorer quality of life in 2011. Conclusions: Thus, depressive and anxiety disorders were persistent/recurrent in one quarter of participants, significantly affecting education and quality of life. Young adults with these disorders need support to achieve their academic goals.

description: Observations and modeling suggest that the dust abundance (gas-to-dust ratio, G/D) depends on (surface) density. The variations of the G/D provide constraints on the timescales for the different processes involved in the lifecycle of metals in galaxies. Recent G/D measurements based on Herschel data suggest a factor 5---10 decrease in the dust abundance between the dense and diffuse interstellar medium (ISM) in the Magellanic Clouds. However, the relative nature of the Herschel measurements precludes definitive conclusions on the magnitude of those variations. We investigate the variations of the dust abundance in the LMC and SMC using all-sky far-infrared surveys, which do not suffer from the limitations of Herschel on their zero-point calibration. We stack the dust spectral energy distribution (SED) at 100, 350, 550, and 850 microns from IRAS and Planck in intervals of gas surface density, model the stacked SEDs to derive the dust surface density, and constrain the relation between G/D and gas surface density in the range 10---100 \Msu pc$^{-2}$ on $\sim$ 80 pc scales. We find that G/D decreases by factors of 3 (from 1500 to 500) in the LMC and 7 (from 1.5$\times 10^4$ to 2000) in the SMC between the diffuse and dense ISM. The surface density dependence of G/D is consistent with elemental depletions and with simple modeling of the accretion of gas-phase metals onto dust grains. This result has important implications for the sub-grid modeling of galaxy evolution, and for the calibration of dust-based gas mass estimates, both locally and at high-redshift.

description: Disruptive collisions have been regarded as an important process for planet formation, while non-disruptive, small-scale collisions (hereafter called erosive collisions) have been underestimated or neglected by many studies. However, recent studies have suggested that erosive collisions are also important to the growth of planets, because they are much more frequent than disruptive collisions. Although the thresholds of the specific impact energy for disruptive collisions (Q_RD^*) have been investigated well, there is no reliable model for erosive collisions. In this study, we systematically carried out impact simulations of gravity-dominated planetesimals for a wide range of specific impact energy (Q_R) from disruptive collisions (Q_R ~ Q_RD^*) to erosive ones (Q_R << Q_RD^*) using the smoothed particle hydrodynamics method. We found that the ejected mass normalized by the total mass (M_ej/M_tot) depends on the numerical resolution, the target radius (R_tar) and the impact velocity (v_imp), as well as on Q_R, but that it can be nicely scaled by Q_RD^* for the parameter ranges investigated (R_tar = 30-300 km, v_imp = 2-5 km/s). This means that M_ej/M_tot depends only on Q_R/Q_RD^* in these parameter ranges. We confirmed that the collision outcomes for much less erosive collisions (Q_R < 0.01 Q_RD^*) converge to the results of an impact onto a planar target for various impact angles and that M_ej/M_tot = C * QR/QRD* holds. For disruptive collisions (Q_R ~ Q_RD^*), the curvature of the target has a significant effect on Mej/Mtot. We also examined the angle-averaged value of M_ej/M_tot and found that the numerically obtained relation between angle-averaged M_ej/M_tot and Q_R/Q_RD^* is very similar to the cases for 45-degree impacts. We proposed a new erosion model based on our numerical simulations for future research on planet formation with collisional erosion.

description: The ring-like structures in protoplanetary discs that are observed in the cold dust emission by ALMA, might be explained by dust aggregates trapped aerodynamically in pressure maxima. The effect of a transient pressure maximum is investigated that develops between two regimes with different turbulent levels. We study how such a pressure maximum collects dust aggregates and transforms them into large planetesimals and Moon-mass cores that can further grow to a few Earth-mass planets by pebble accretion, and eventually to giant planets, by considering the accretion of a gaseous envelope. A numerical model is developed, incorporating the evolution of gaseous disc, growth and transport of pebbles, N-body interactions of growing planetary cores and their backreaction to gas disc by opening a partial gap. Planetesimal formation by streaming instability is parametrized in our model. A transient pressure maximum efficiently accumulates dust particles that can grow larger than mm-size. If this happens, dust aggregates can be transformed by the streaming instability process into such large planetesimals, which can grow further by pebble accretion, according to our assumptions. As the gas evolves to its steady state, the pressure maximum vanishes, and the concentrated pebbles that are not transformed to planetesimals and accreted by the growing planet, drift inward. During this inward drift, if the conditions of the streaming instability are met, planetesimals are formed in a wide radial range of the disc. Conclusions. A transient pressure maximum is a favourable place for planetesimal and planet formation during its lifetime and the concentration of pebbles induces continuous formation of planetesimals even after its disappearance. Besides, the formation of a planet can trigger the formation of planetesimals over a wide area of the protoplanetary disc.

description: A gradual solar energetic particle (SEP) event is thought to happen when particles are accelerated at a shock due to a fast coronal mass ejection (CME). To quantify what kind of solar eruptions can result in such SEP events, we have conducted detailed investigations on the characteristics of CMEs, solar flares and m-to-DH wavelength type II radio bursts (herein after m-to-DH type II bursts) for SEP-associated and non-SEP-associated events, observed during the period of 1997-2012. Interestingly, 65% of m-to-DH type II bursts associated with CMEs and flares produced SEP events. The SEP-associated CMEs have higher sky-plane mean speed, projection corrected speed, and sky-plane peak speed than those of non-SEP-associated CMEs respectively by 30%, 39%, and 25%, even though the two sets of CMEs achieved their sky-plane peak speeds at nearly similar heights within LASCO field of view. We found Pearson's correlation coefficients between the speeds of CMEs speeds and logarithmic peak intensity of SEP events are cc = 0.62 and cc = 0.58, respectively. We also found that the SEP-associated CMEs are on average of three times more decelerated (-21.52 m/s2) than the non-SEP-associated CMEs (-5.63 m/s2). The SEP-associated m type II bursts have higher frequency drift rate and associated shock speed than those of the non-SEP-associated events by 70% and 25% respectively. The average formation heights of m and DH type II radio bursts for SEP-associated events are lower than for non-SEP-associated events. 93% of SEP-associated events originate from the western hemisphere and 65% of SEP-associated events are associated with interacting CMEs. The obtained results indicate that, at least for the set of CMEs associated with m-to-DH type II bursts, SEP-associated CMEs are more energetic than those not associated with SEPs, thus suggesting that they are effective particle accelerators.

description: Climbing plants rely on suitable support to provide the light conditions they require in the canopy. Negative phototropism is a directional search behavior proposed to detect a support-tree, which indicates growth or movement away from light, based on light attenuation. In a Chilean temperate rainforest, we addressed whether the massive woody climber Hydrangea serratifolia (H. et A.) F. Phil (Hydrangeaceae) presents a support-tree location pattern influenced by light availability. We analyzed direction and light received in two groups of juvenile shoots: searching shoots (SS), with plagiotropic (creeping) growth vs. ascending shoots (AS), with orthotropic growth. We found that, in accordance with light attenuation, SS and AS used directional orientation to search and then ascend host trees. The light available to H. serratifolia searching shoots was less than that of the general forest understory; the directional orientation in both groups showed a significant deviation from a random distribution, with no circular statistical difference between them. Circular-linear regression indicated a relationship between directional orientations and light availability. Negative phototropism encodes the light environment’s heterogeneous spatial and temporal information, guiding the shoot apex to the most shaded part of the support-tree base, the climbing start point.
