description: We explore two widely used empirical models for the galaxy-halo connection, subhalo abundance matching (SHAM) and the halo occupation distribution (HOD) and compare their predictions with the hydrodynamical simulation IllustrisTNG (TNG) for a range of statistics that quantify the galaxy distribution at $n_{\rm gal}\approx1.3\times10^{-3}\,[{\rm Mpc}/h]^{-3}$. We observe that in their most straightforward implementations, both models fail to reproduce the two-point clustering measured in TNG. We find that SHAM models constructed using the relaxation velocity, $V_{\rm relax}$, and the peak velocity, $V_{\rm peak}$, perform best, and match the clustering reasonably well, although neither model captures adequately the one-halo clustering. Splitting the total sample into sub-populations, we discover that SHAM overpredicts the clustering of high-mass, blue, star-forming, and late-forming galaxies and uderpredicts that of low-mass, red, quiescent, and early-forming galaxies. We also study various baryonic effects, finding that subhalos in the dark-mater-only simulation have consistently higher values of their SHAM-proxy properties than their full-physics counterparts. We then consider a two-dimensional implementation of the HOD model augmented with a secondary parameter (environment, velocity anisotropy, $σ^2R_{\rm halfmass}$, and total potential) and tuned so as to match the two-point clustering of the IllustrisTNG galaxies on large scales. We analyze these galaxy populations adopting alternative statistical tools such as galaxy-galaxy lensing, void-galaxy cross-correlations and cumulants of the smoothed density field, finding that the hydrodynamical galaxy distribution disfavors $σ^2 R_{\rm halfmass}$ and the total potential as secondary parameters, while the environment and velocity anisotropy samples are consistent with full-physics across all statistical probes examined.

description: We present results of analysis of a bursting behavior of a low mass X-ray binary system SLX 1735-269 during INTEGRAL observations of the Galactic Center region in 2003. There were detected 6 type I X-ray bursts in total, with one being much longer and more powerful then others. A strong dependence of the bursts recurrence time on the mass accretion rate is observed, that is likely caused by the change in the burning regime. The long burst demonstrated a photospheric radius expansion. We discuss possible scenarios of this long burst and show that it is unlikely a carbon burning flash and rather a burst of large pile of hydrogen and helium accelerated by electron capture processes in a dense accumulated layer.

Improved approximate inspirals of test-bodies into Kerr black holes

description: We present an improved version of the approximate scheme for generating inspirals of test-bodies into a Kerr black hole recently developed by Glampedakis, Hughes and Kennefick. Their original "hybrid" scheme was based on combining exact relativistic expressions for the evolution of the orbital elements (the semi-latus rectum p and eccentricity e) with approximate, weak-field, formula for the energy and angular momentum fluxes, amended by the assumption of constant inclination angle, iota, during the inspiral. Despite the fact that the resulting inspirals were overall well-behaved, certain pathologies remained for orbits in the strong field regime and for orbits which are nearly circular and/or nearly polar. In this paper we eliminate these problems by incorporating an array of improvements in the approximate fluxes. Firstly, we add certain corrections which ensure the correct behaviour of the fluxes in the limit of vanishing eccentricity and/or 90 degrees inclination. Secondly, we use higher order post-Newtonian formulae, adapted for generic orbits. Thirdly, we drop the assumption of constant inclination. Instead, we first evolve the Carter constant by means of an approximate post-Newtonian expression and subsequently extract the evolution of iota. Finally, we improve the evolution of circular orbits by using fits to the angular momentum and inclination evolution determined by Teukolsky based calculations. As an application of the improved scheme we provide a sample of generic Kerr inspirals and for the specific case of nearly circular orbits we locate the critical radius where orbits begin to decircularise under radiation reaction. These easy-to-generate inspirals should become a useful tool for exploring LISA data analysis issues and may ultimately play a role in source detection.

Lambda Production at Forward and Backward Rapidity in d+Au Collisions at sqrt(s_NN) = 200 GeV

description: Using the forward time projection chambers of the STAR experiment at the Brookhaven Relativistic Heavy Ion Collider we measure the centrality dependent Lambda and Anti-Lambda yields and inverse slope parameters in d+Au collisions at forward and backward rapidities y = +- 2.75. The contributions of different processes to stopping and baryon transport are probed exploiting the inherent asymmetry of the d+Au system. Comparisons to model calculations show that the baryon transport on the deuteron side is due to multiple collisions of the deuteron nucleons with gold participants. On the gold side, the inclusion of inital state nuclear effects or hadronic rescattering is necessary to describe the data.

description: A complex study of aging kinetics for both coarse-grained and nanostructured by severe plastic deformation Cu -- 2 wt% Be alloy is reported. It is shown that aging of a coarse-grained alloy leads to continuous formation of nanosized CuBe body centred cubic (bcc, CsCl -- type) semi-coherent particles with the {220} Cu // {200} CuBe crystallographic orientation relationship. These particles created significant internal stress fields and became obstacles for dislocation glide that resulted in a change in the hardness from 95 Vickers hardness (HV) for the solubilized alloy to 400 HV for the aged one. The severe plastic deformation led to the formation of a single-phase nanograined microstructure with an average grain size of 20 nm and 390 HV. It was found that this grain size was slightly driven by grain boundary segregation. Further aging of the nanocrystalline alloy led to the discontinuous formation of precipitates on the former Cu grain boundaries and skipping of metastable phases. Significant age hardening with a maximum hardness of 466 HV for the aged nanostructured alloy was observed. Mechanical tests result revealed a strong influence of microstructure and further aging on strength capability of the alloy for both coarse-grained and nanostructured alloy. A good thermal stability in the nanostructured alloy was also noticed. Theoretical calculations of the hardness value for the CuBe phase are provided. It was shown that Be as a light alloying elements could be used for direct change of microstructure of severely deformed copper alloys.

description: We report a search for CP-violating asymmetry in B0 -> D*+- D-+ decays. The analysis employs two methods of B0 reconstruction: full and partial. In the full reconstruction method all daughter particles of the B0 are required to be detected; the partial reconstruction technique requires a fully reconstructed D- and only a slow pion from the D*+ -> D0 pi_slow+ decay. From a fit to the distribution of the time interval corresponding to the distance between two B meson decay points we calculate the CP-violating parameters and find the significance of nonzero CP asymmetry to be 2.7 standard deviations.

description: The H-formulation, used abundantly for the simulation of high temperature superconductors, has shown to be a very versatile and easily implementable way of modeling electromagnetic phenomena involving superconducting materials. However, the simulation of a full vector field in current-free domains unnecessarily adds degrees of freedom to the model, thereby increasing computation times. In this contribution, we implement the well known H-$ϕ$ formulation in COMSOL Multiphysics in order to compare the numerical performance of the H and H-$ϕ$ formulations in the context of computing the magnetization of bulk superconductors. We show that the H-$ϕ$ formulation can reduce the number of degrees of freedom and computation times by nearly a factor of two for a given relative error. The accuracy of the magnetic fields obtained with both formulations are demonstrated to be similar. The computational benefits of the H-$ϕ$ formulation are shown to far outweigh the added complexity of its implementation, especially in 3-D. Finally, we identify the ideal element orders for both H and H-$ϕ$ formulations to be quartic in 2-D and cubic in 3-D, corresponding to the highest element orders implementable in COMSOL.

description: On agro-food products’ market of the European Market a saturation of products has been reached, attaining the stage of limitation, by means of certain policies and specific levers, of the expansion of this market. Romania faced the situation of member state of EU, when, after year 2006, it entered a harsh competition, in which the predominant word is saturation. This is the reason for which the post-accession studies in agriculture must aim both at valorizing the natural potential of not-exploited or less exploited resources of Romania, and at finding out solutions to increase competitiveness of the field, in which Romania feels threatened, aiming first of all at the markets of traditional products. Competitiveness is based on criteria of economic efficiency, according to which an important place takes the rational and efficient exploitation of the natural resources, especially in agriculture. In order to point out the significance of MAP cultures, we will make a comparison of some indicators of efficience of the wheat, corn, colza cultures and several medicinal plants which were cultivated and studied. The comparison will be made taking into consideration both the data of average efficiency in case of MAP (using classical technologies, without applying the knowledge discovered by the researches of the field), and the maximal ones on the crops and MAP cultures (by application of knowledge resulted from agronomic research specific for the improvement of the technology of each species of MAP). This field MAP is so much the more important for Romania as this country owns elements of environment favourable for a potential exploitation of the medical aromatic plants, without affecting the traditional cultures in the agricultural areas.

The women’s movement in China : social movement theories and the Chinese Experience
Creators: name: Trinh, Linh Yen
Publisher: name: University of British Columbia
Year: 2009

description: The women's movement in China has experienced salient growth and development over the past two decades. Since the introduction of economic reforms in the late 1970s, it had begun the process of moving from being a dependent, state-led entity to becoming a more separate and autonomous one. This paper examines the factors that have transpired within the movement that have given rise to this development. Specifically, three factors will be explored: the shifting emphasis between the concepts of sameness and difference at various times throughout the history of the movement; the issue of agency - the proactive versus reactive nature of the movement; and, the renewed and expanding role of the All-China Women's Federation (a mass organization within the state structure). The social movements approach will be used to analyze these factors. This approach lends itself well to the examination of the complexities that have characterized the transformation of the Chinese women's movement, especially if a synthesis of the various theories within the approach is carried out. The synthesis I will employ in this paper will take the form of a multi-level analysis of the movement's development - in particular: the macro- (the broader environment and structures encountered by women), micro- (the changes occurring within women themselves), and meso- (the participation and action of women) levels. A multi-level approach will not only reveal the peculiarities of the Chinese case of the women's movement, but will also show how the confluence of the various factors at each level has contributed to its increasing independence since the beginning of the Reform era. Ultimately, I would argue that analyzing the Chinese women's movement through the lens of the social movements approach could aptly inform debates and discussions about the prospects and process of change that has been taking place at a rapid pace in modern China.

description: The aim of this study is to describe a protocol for evaluating the effects of transcutaneous electrical nerve stimulation (TENS) on pain following breast augmentation surgery. Fifty-four women will be randomly allocated into two groups: active TENS and placebo. Pain will be assessed at rest and during movement, before and immediately after TENS application. Secondary outcomes include pain one-hour post-treatment, respiratory muscle strength, patient satisfaction, and analgesic use in the first four hours post-surgery. The results of this clinical trial could enhance the management of post-operative pain in breast augmentation surgery using non-pharmacological interventions, potentially reducing costs and improving patient experience. Clinical Trial Registration: RBR-96h3k97 What is this article about? This study investigates the effectiveness of transcutaneous electrical nerve stimulation (TENS) in reducing pain after breast augmentation surgery. Breast augmentation is a procedure that can cause postoperative pain. Analgesics are typically used to alleviate this pain, but they can have side effects and delay recovery. TENS is a non-drug alternative that can relieve pain by stimulating nerve fibers. However, it is still unknown whether TENS is effective for this type of surgery. What do the results of the study mean? If TENS reduces pain, it could be a non-drug alternative for pain management, offering a faster recovery and better experience for patients, as well as reducing the costs associated with analgesic use. This could help develop new strategies for postoperative pain management.

description: We investigate the connection between ionized gas outflows and star formation activity using a large sample of type 1 and 2 AGNs with far-IR detections or star formation rate (SFR) estimates. The strength of ionized gas outflows, measured by the velocity dispersion and velocity shift of the \OIII\ emission line, clearly shows a correlation with SFR. The connection between specific star formation rate (sSFR) and \OIII\ gas velocity dispersion indicates that AGNs with stronger outflows are hosted by galaxies with higher SFR. Compared to star-forming galaxies in the main sequence, both type 1 and type 2 AGNs show sSFR similar to that of non-AGN galaxies, indicating no instantaneous AGN feedback, while sSFR is higher (lower) for AGNs with stronger (weaker) outflows than that of main sequence galaxies. These results are consistent with a delayed AGN feedback scenario. However, it is also possible that a decease/increase of gas fraction may cause the correlation without AGN feedback.

Subjects: Research and Development/Tech Change/Emerging Technologies

description: Environmental research has been increasing due to growing diverse environmental concerns regarding sustainability, climate change, natural resource depletion, waste management, and air and noise pollution. Economic valuation of environmental research can assist in guiding research planning and expenditure. Yet environmental research is difficult to evaluate due to the dominance of non-market benefits and difficulties identifying tangible outputs and outcomes from research. This paper attempts to apply an existing valuation framework to an empirical case study to examine the difficulties and limitations of economic valuations of environmental research. In the empirical case study environmental research and other technical and managerial inputs were used to develop a policy output. Policy implementation will result in environmental outcomes with subsequent economic benefits. The primary purpose of this paper is to explore the complexities and limitations of valuing environmental research, in particular the counterfactual and uncertainty. Section 2 outlines the generic framework for valuing environmental research. Section 3 describes the valuation method used in this empirical analysis. Section 4 provides background to the case study and applies the chosen method to value the environmental research. The limitations encountered during the assessment are highlighted in Section 5, and Section 6 concludes with final comments regarding economic valuations of environmental research.

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider the strong dynamics associated with a composite Higgs model that simultaneously produces dynamical axions and solves the strong CP problem. The strong dynamics arises from a new $Sp$ or $SU(4)$ hypercolor gauge group containing QCD colored hyperfermions that confines at a high scale. The hypercolor global symmetry is weakly gauged by the Standard Model electroweak gauge group and an enlarged color group, $SU(N+3) \times SU(N)'$. When hyperfermion condensates form, they not only lead to an $SU(5)/SO(5)$ composite Higgs model but also spontaneously break the enlarged color group to $SU(3)_c \times SU(N)_D$. At lower energies, the $SU(N)_D$ group confines, producing two dynamical axions that eliminates all CP violation. Furthermore, small instantons from the $SU(N)'$ group can enhance the axion mass, giving rise to TeV scale axion masses that can be detected at collider experiments. Our model provides a way to unify the composite Higgs with dynamical axions, without introducing new elementary scalar fields, while also extending the range of axion masses that addresses the strong CP problem.

Defining property rights to water in complex regulated river systems: generalising the capacity sharing concept

Year: 2010
Subjects: Resource /Energy Economics and Policy

description: It is commonly noted that Australian water rights, specifically those prevailing within the Murray-Darling Basin, represent a significant departure from hydrological reality (see for example Young and McColl 2009). Where water rights depart from the physical realities of water supply networks, water use and water trade decisions may result in external effects and associated allocative inefficiency. This paper examines how a more exclusive set of water property rights based around the concept of capacity sharing (Dudley and Musgrave 1988) might be defined and implemented in complex regulated river systems. In particular, the paper considers how the capacity sharing concept might be generalised to accommodate complex water supply systems (e.g. with multiple storages and or unregulated river flows) and large regulated river basins (e.g. with multiple connected water supply systems). Previous research on water storage rights and capacity sharing (Hughes 2009, Brennan 2008) focused extensively on intertemporal efficiency. In this paper the focus is primarily on spatial efficiency, in particular the potential to improve efficiency by incorporating a more accurate representation of water supply networks into water property rights. The paper also considers some of the challenges that may be associated with implementing such a system of water property rights, including distributional consequences, transaction costs and aspects of ‘jointness’ in the delivery and consumption of water.

description: Post-mastectomy pain syndrome is a common postoperative complication that can impact patient quality of life and function. The aim of this systematic review is to evaluate the effectiveness of cryoneurolysis as an intervention for the management of post-mastectomy pain. A prospero-registered systematic review was performed following PRISMA 2020 guidelines. An initial screening consisted of 53 articles imported from the following databases: PubMed, Embase, Web of Science, Cochrane, and Scopus. Google Scholar and WorldCat were also searched to pull any further articles. Three clinical trials, one case series, and one case report were included. Primary outcome measure of patient reported pain score (VAS or NRS) showed clinically significant reduction in pain in all five studies. Three of the studies also reported reduction in opioid use with cryoneurolysis intervention. A pooled effect size of Hedges g = –0.963, (95% CI [−1.55, −0.373]), with heterogeneity (I2 = 0.70). Cryoneurolysis intervention shows promising and clinically significant relief in post-mastectomy pain in patients and further studies are encouraged. Post-mastectomy pain syndrome is when people continue to feel pain long after breast surgery. One way to help this pain is cryoneurolysis. The doctor uses a probe to freeze certain nerves, stopping the body’s pain signal. This study looked at the results from five experiments and found that these patients’ pain got a lot better. But, there were not too many participants in the study, so we should continue to research this area. WIth more research we can figure out the best techniques and make sure there are no long-term side effects before using this treatment on a larger group of people
Theoretical Estimation of Attenuation Coefficient of Resonant Ultrasound Contrast Agents

Publisher: name: arXiv
Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Acoustic characterization of ultrasound contrast agents (UCAs, coated microbubbles) relies on the attenuation theory that assumes the UCAs oscillate linearly at sufficiently low excitation pressures. Effective shell parameters of the UCAs can be estimated by fitting a theoretical attenuation curve to experimentally measured attenuation data. Depending on the excitation frequency and properties of the shell, however, an UCA may oscillate nonlinearly even at sufficiently low excitation pressures violating the assumption in the linear attenuation theory. Notably, the concern on the estimation of the attenuation coefficient of a microbubble at resonance using linearized approximation has long been addressed. In this article, we investigated the attenuation phenomenon through analyzing the energy dissipation of a single UCA and propagating waves in an UCA suspension, both of which employed a nonlinear Rayleigh-Plesset equation. Analytical formulae capable of estimating the attenuation coefficient due to the weakly nonlinear oscillations of the UCA were obtained with a relatively rigorous mathematical analysis. The computed results that were verified by numerical simulations showed the attenuation coefficient of the UCA at resonance was pressure-dependent and could be significantly smaller than that predicted by the linear attenuation theory. Polydispersity of the UCA population enlarged the difference in the estimation of attenuation between the linear and present second-order nonlinear theories.

description: A 12-year experiment designed to show the benefits of applying lime to acid soils when growing annual pasture, perennial pasture, and annual crops in rotations with annual or perennial pastures, provides the context for comparing methods of economic analysis. In this study enterprise gross margins are compared with whole-farm cumulative monthly cash flows derived using a business process model. The current study gave gross margins comparable with those of a recently published study based on the first 12 years of the same field experiment at Book Book near Wagga Wagga in southern NSW (Li et al., 2010). Both gross margin analyses indicated positive results for all treatments. However, because key fixed and capital cost items were not taken into account in the gross margin analysis the financial benefits of the treatments were overstated. In the whole-farm analysis, a full set of accounts (including fixed and capital costs) was developed for the experimental combinations of prime lamb and dryland cropping enterprises and used to generate a monthly cash flow sequence for each treatment over the 12-year term of the experiment. This full financial analysis, where all costs are included, showed all mixed treatments (cropping and grazing) accumulated unsustainable losses over the period of the trial. The grazing-only treatments generated positive cash lows over the 12 year period, but 2 accumulated high levels of debt in the initial years. None of these outcomes were predicted by gross margins, which were consistently positive for all treatments. This paper concludes that the analysis of trial results benefits from interpretation in the context of whole-farm analysis, verified by district experience. Relying on gross margin analysis alone would have supported loss-making outcomes in this trial. This conclusion has important ramifications for analysis of all systems trials.

description: This paper explores the extent and nature of anchoring and shift effects in a double-bounded contingent valuation of recreational fishing in Tasmania’s inshore saltwater fishery. In particular we model the situation where respondents, when answering the second valuation question, evaluate the bid amount partly with reference to the size of the first bid amount. The estimates of the coefficients and mean WTP for a day of fishing are compared across different contingent valuation models, including a single-bounded model, a conventional double-bounded model and models that control anchoring and exogenous shift effects in both homogeneous and heterogeneous forms. Overall we find consistent evidence of anchoring, but mixed evidence of a shift effect. Results show that both males and females anchor in the same way, but that respondents who have a mainstream view of what recreational fishing represents anchor more strongly than those whose view of fishing is not mainstream. The estimated mean WTP for a day’s recreational fishing is consistently higher in all models which account for bias in responses than in either the single-bounded or double-bounded models. We indicate the possibility that anchoring behaviour may be more complex than is captured in our models and suggest that this needs to be addressed if the results of contingent valuations are to reliably inform resource allocation decisions and recreational fishing management.

description: Modern farming in Australia is no longer simple. Farms are large, multi-enterprise businesses underpinned by expensive capital investments, changing production technologies, volatile markets and pervasive regulation. The complexity of modern broadacre farming leads to the question: what is the nature of the relationship between farm business complexity and farm profitability? This study uses bioeconomic farm modelling and employs eight measures of complexity to examine the profitability and complexity of a wide range of broadacre farming systems in Australia. Rank order correlations between farm profitability and each measure of complexity show inconsistent relationships, although the most profitable farming systems are found to be reasonably complex on several criteria. Among the set of highly profitable systems are found some characterised by less complexity. Using the farmer’s annual hours worked as a measure of complexity that affects current farm management, the trade-off between profit and this measure of complexity is found not to be large. A case is outlined where the farmer’s annual hours worked could be reduced by 9 percent for a 3 percent reduction in farm profit. If farmers’ workloads are proving problematic now and in the future, then agricultural R&D, service delivery and policy development will need to focus much more on being highly attractive to time-poor farm managers.

description: We present results from two statistical analyses applied to an neutral hydrogen (HI) dataset of the nearby tidal bridge in the Magellanic System. Primarily, analyses of the Spatial Power Spectrum suggest that the Magellanic Bridge, historically considered to be a single contiguous feature, may in fact be a projection of two kinematically and morphologically distinct structures. The southern and more obviously turbulent parts appear to show structure organized similarly to the adjacent Small Magellanic Cloud (SMC), while the northern regions are shown to be relatively deficient in large scale power. The extent of modification to the spatial power index by the velocity fluctuations is also highly variant across these parts of the Bridge. We find again that the northern part appears distinct from the southern part and from the SMC, in that the power spectrum is significantly more affected by slower velocity perturbations. We also probe the rate of spectral variation of the HI by measuring the Spectral Correlation Function over selected regions. The results from this analysis highlight a tendency for the HI spectra within the bright parts of the Bridge to have a more persistent correlation in the E-W direction than in the N-S direction. These results are considered to be quantitative evidence for the tidal processes which are thought to have been active throughout the evolution of the Magellanic Bridge

All-electron Gaussian-based $G_0W_0$ for Valence and Core Excitation Energies of Periodic Systems

description: We describe an all-electron $G_0W_0$ implementation for periodic systems with $k$-point sampling implemented in a crystalline Gaussian basis. Our full-frequency $G_0W_0$ method relies on efficient Gaussian density fitting integrals and includes both analytic continuation and contour deformation schemes. Due to the compactness of Gaussian bases, no virtual state truncation is required as is seen in many plane-wave formulations. Finite size corrections are included by taking the $q \to 0$ limit of the Coulomb divergence. Using our implementation, we study quasiparticle energies and band structures across a range of systems including molecules, semiconductors, rare gas solids, and metals. We find that the $G_0W_0$ band gaps of traditional semiconductors converge rapidly with respect to the basis size, even for the conventionally challenging case of ZnO. Using correlation-consistent bases of polarized triple-zeta quality, we find the mean absolute relative error of the extrapolated $G_0W_0$@PBE band gaps to be only 5.2% when compared to experimental values. For core excitation binding energies (CEBEs), we find that $G_0W_0$ predictions improve significantly over those from DFT if the $G_0W_0$ calculations are started from hybrid functionals with a high percentage of exact exchange.

description: Choice Experiments (CE) are increasingly used to estimate the values of environmental goods and services. CE questionnaires represent the environmental good under valuation by varying levels of non-market attributes. Inclusion of a cost attribute enables the estimation of monetary values for changes in the non-market attributes presented. The ways in which the levels of the attributes are described in the survey - the ‘attribute frame’ - may affect respondents’ choices. Furthermore, varying levels of the cost attribute may impact CE value estimates. The challenge for CE practitioners is to identify the ‘appropriate’ attribute frames and cost levels. In this paper, the impacts of changing cost levels and the impacts of describing non-market attributes as absolute levels or in relative terms are assessed. These tests were performed using data from a CE on catchment management in Tasmania, Australia. Contrary to a priori expectations, including explicit information cues about relative attribute levels in the choice sets is found not to affect stated preferences. However, comparisons between different split samples provide evidence that respondents’ preferences are impacted by changing the range in cost attribute levels, with higher levels leading to significantly higher estimates of WTP for one of the three environmental attributes.

description: Phantom limb pain (PLP) is a painful sensation occurring in patients around the site of an amputation. The aim of this systematic review is to evaluate the efficacy of cryoneurolysis in the management of phantom limb pain. A systematic review was performed according to the PRISMA 2020 guidelines. An initial search yielded 200 articles from four major scientific databases (PubMed, Embase, Cochrane Library, WebOfScience). Five articles met inclusion criteria, four of which underwent additional pooled statistical analysis. Pooled analysis of the included trials revealed a cumulative Cohen’s d effect size of 1.55 (95% CI [0.24, 2.87]; p = 0.02; z = 2.32) for the reduction of pain on a 10-point pain scale following cryoneurolysis intervention. The remaining article that did not meet inclusion criteria for statistical analysis was a case report that reported a reduction in pain from 9/10 to 1/10 one week following intervention. The large effect size demonstrated a statistically and clinically significant improvement in patient-reported pain. Additionally, patients may be able to reduce their amount of pharmaceutical pain management with successful cryoneurolysis treatment. However, these findings are limited by the small sample size and high heterogeneity between studies. Further high-quality studies should be performed to corroborate these findings. www.crd.york.ac.uk/prospero identifier is CRD42024543085. Phantom limb pain (PLP) is a challenging condition where individuals feel pain in the area where a limb has been amputated. This systematic review examined the use of cryoneurolysis, a procedure that freezes nerves to reduce pain, to manage PLP. Researchers followed PRISMA 2020 guidelines for the review, analyzing studies from major databases, including PubMed and Cochrane Library. Out of 200 initial studies, five met the criteria for inclusion, with four providing data for a combined statistical analysis. The fifth study, a case report, was analyzed separately. The analysis showed a large positive effect of cryoneurolysis on reducing PLP. On a 10-point pain scale, patients reported significant pain relief, with the pooled data showing a strong reduction in pain scores. In the case report, the patient’s pain dropped from a severe 9/10 to a mild 1/10 just one week after the treatment. The findings suggest that cryoneurolysis is an effective option for reducing PLP and may also allow patients to use less medication to manage their pain. However, the conclusions are limited by the small number of studies and differences in study methods. More high-quality research is needed to confirm these promising results.
