Clinical Improvement Following Operative Management of Ankle Fractures Among Patients With and Without Moderate to High Depressive Symptoms: An Analysis Using PROMIS

Background: Understanding the recovery trajectory following operative management of ankle fractures can help surgeons guide patient expectations. Further, it is beneficial to consider the impact of mental health on the recovery trajectory. Our study aimed to address the paucity of literature focused on understanding the recovery trajectory following surgery for ankle fractures, including in patients with depressive symptoms. Methods: From February 2015 to March 2020, patients with isolated ankle fractures were asked to complete Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), Pain Interference (PI), and Depression questionnaires as part of routine care at presentation and follow-up time points. Linear mixed effects regression models were used to evaluate the patient recovery pattern, comparing the preoperative time point to <3 months, 3-6 months, and >6 months across all patients. Additional models that included the presence of depression symptoms as a covariate were then used. Results: A total of 153 patients met inclusion criteria. By 3-6 months, PROMIS PF (β: 9.95, 95% CI: 7.97-11.94, P < .001), PI (β: −10.30, 95% CI: −11.87 to −8.72, P < .001), and Depression (β: −5.60, 95% CI: −7.01 to −4.20, P < .001) improved relative to the preoperative time point. This level of recovery was sustained thereafter. When incorporating depressive symptoms into our model as a covariate, the moderate to high depressive symptoms were associated with significantly and clinically important worse PROMIS PF (β: −4.00, 95% CI: −7.00 to −1.00, P = .01) and PI (β: 3.16, 95% CI: −0.55 to 5.76, P = .02) scores. Conclusion: Following ankle fracture surgery, all patients tend to clinically improve by 3-6 months postoperatively and then continue to appreciate this clinical improvement. Although patients with moderate to high depressive symptoms also clinically improve following the same trajectory, they tend to do so to a lesser level than those who have low depressive symptoms. Level of Evidence: Level III, case-control study.
Expanding the boundaries of interdisciplinary field: Contribution of Network Science journal to the development of network science

Abstract In this paper, we examine the contribution of Network Science journal to the network science discipline. We do so from two perspectives. First, expanding the existing taxonomy of article contribution, we examine trends in theory testing, theory building, and new method development within the journal’s articles. We find that the journal demands a high level of theoretical contribution and methodological rigor. High levels of theoretical and methodological contribution become significant predictors of article citation rates. Second, we look at the composition of the studies in Network Science and determine that the journal has already established a solid “hard core” for the new discipline.
Self-Fourier functions and coherent laser combination

The Gaussian and Comb functions are generally quoted as being the two basic functions that are their own Fourier transforms. In 1991, Caola presented a recipe for generating functions that are their own Fourier transforms by symmetrizing any transformable function and then adding its own Fourier transform to it. In this letter, we present a new method for generating a set of functions that are exactly their own Fourier transforms, and which have direct application to laser cavity design for a wide variety of applications. The generated set includes the Gaussian and Comb functions as special cases and forms a continuous bridge of functions between them. The new generating method uses the Gaussian and Comb functions as bases and does not rely on the Fourier operator itself. This self-Fourier function promises to be particularly useful in high-power laser design through coherent laser beam combination. Although these results are presented in a single dimension as with a linear array, the results are equally valid in two dimensions.
Research on Grid Positioning Strategy of Coupling Mechanism in Wireless Charging System With Offset Angle Variable

The precise positioning of receiving and transmitting coils of the wireless power transmission system is the precondition for its efficient operation, and it is necessary and indispensable in practice. The novel grid positioning model and algorithm of four pick-up coils with angles is established by adding the deflection angle of the receiving coil. The corresponding relationship between space magnetic field and pickup coil voltage is analyzed, and the method of magnetic field reconstruction is studied in this article. Then, considering the sampling workload and effectiveness of pick-up coil voltages at grid point, the pick-up coil voltages were reconstructed and expanded based on variable slope interpartition sampling and Kriging interpolation, to increase the positioning database. It is found that the positioning accuracy of receiving coil can be improved with the grid sampling interval density increasing, or by using variable slope sampling while the number of grid sampling is unchanged. Under the grid sampling interval of 2.5 cm, the average positioning error of the system is less than 1 cm in this article, and the experimental results are basically consistent with the theoretical results, and the validity of the proposed approach is verified.
Linearization problem in pseudolite surveys

Abstract GPS augmented with pseudolites (PL), can be used in various engineering surveys. Also pseudolite—only navigation system can be designed and used in any place, even if GPS signal is not available (Kee et al. Development of indoor navigation system using asynchronous pseudolites, 1038–1045, 2000). Especially in engineering surveys, where harsh survey environment is common, pseudolites have a lot of applications. Pseudolites may be used in construction sites, open pit mines, city canyons, GPS and PL baseline processing is similar, although there are few differences that must be taken into account. One of the major issues is linearization problem. The source of the problem is neglecting second terms of Taylor series expansion in GPS baseline processing software. This problem occurs when the pseudolite is relatively close to the receiver, which is the case in PL surveys. In this paper authors presents the algorithm for GPS + PL data processing including, neglected in classical GPS only approach, second terms of Taylor series expansion. The mathematical model of adjustment problem, detailed proposal of application in baseline processing algorithms, and numerical tests are presented.
Health Problems, Healthcare Service Utilisation and its Associated Factors Among the Homeless In Malaysia: A Systematic Review

Background : Homelessness is a growing concern since it affects many individuals worldwide. Homeless people are vulnerable to health problems but tend to underutilise health services. Despite being a worldwide concern, there is little research on health issues and healthcare utilisation among homeless people in Malaysia. Methodology : Three databases were used to search for relevant articles: Scopus, Web of Science, and PubMed. Studies published between 2011 and 2021 that examined the health problems and health service utilisation among homeless adults in Malaysia were considered. Manual searches in reference lists and grey literature were also performed to add reports. Data were extracted manually. The authors conducted a descriptive analysis and narrative synthesis. Results : A total of seven articles ful ﬁ lled the pre-determined inclusion and exclusion criteria. Three themes emerged from the studies: health problems, healthcare service utilisation, and associated factors of healthcare services utilisation. Of the seven articles, reported health problems included drug abuse, alcohol abuse, HIV-positive status, mental health problems, oral health, and other chronic diseases. All included articles reported none to under-utilised health care services. The associated factors of health care utilisations were ﬁ nancial issues, low levels of self-care awareness, feeling embarrassed, low health literacy, and poor social support. Conclusion : Evidence shows that the homeless suffer from a range of health problems. Poor health care utilisations among the homeless are a signi ﬁ cant issue, with several associated factors contributing to that worrying scenario. Future studies among homeless people are needed to provide more information, especially about their health care utilisations. In addition, effective multi-agency interventions are required to address health vulnerabilities.

Antihelminthic Activity of Lophira Lanceolata on Heligmosomoides polygyrus Using an Automated High-Throughput Method

Background There are about 13 parasitic infections that are responsible for significant morbidity and mortality but have not received the attention they deserve; thus, they are now known as “neglected tropical diseases” (NTDs). This study was aimed at evaluating the antihelminthic activities of Lophira lanceolata using an automated high-throughput method. Methods The antihelminthic activity effect of the extracts against H. polygyrus was determined using an automated high-throughput method. For the egg-hatching test, 100 μL of embryonated egg suspension (60 eggs) was added to 100 μL of various concentrations of extracts, levamisole, and 1.5% DMSO in a 96-well round-bottom microtitre plate. After mixing, the 96-well microplate was placed in WMicroTracker and incubated for 24 h at 25°C; the movements were recorded every 30 minutes. The same procedure was used for the larval motility assays, where 100 μL of L1 or L2 larvae (50 larvae) were put in contact with 100 μL of various concentrations of extracts. Results The ovicidal activity (hatching) had an IC50 of 1.4 mg/mL for the ethanol extract. The aqueous and ethanol extracts of L. lanceolata showed larvicidal activity on the L1 larvae with IC50 of 1.85 mg/mL and 2.4 mg/mL, respectively, as well as on the L2 larvae with IC50 values of 1.08 mg/mL and 1.02 mg/mL for the aqueous and ethanol extracts, respectively. These results showed that the aqueous extract exhibited a stronger inhibitory power on the hatching rate of parasites than ethanol extracts, while the contrary effect was observed for the larval motility assays. Conclusion This study provides scientific data on the use of L. lanceolata by the local population for the treatment of helminthiases. However, in vivo and toxicity tests are necessary to assess its activity and safety.
Remote sensing of sea surface salinity: challenges and research directions

ABSTRACT Salinity is a key parameter that affects the surface, deep circulations, and heat transport of oceans. Sea surface salinity (SSS) represents the salinity at the ocean surface and impacts atmosphere – ocean interactions and vertical ocean circulation. To monitor SSS, three passive microwave radiometers with an L-band (1.4 GHz) have been launched since 2009. The scientific need for SSS retrieval and estimation has grown in recent years; however, the operational retrieval of SSS via satellite remote sensing still faces significant challenges. This study provides a review of satellite-based SSS retrieval methods and guidelines to encourage future research. This paper introduces satellite-derived SSS research trends and summarizes the representative SSS satellite sensors and their retrieval methods. The limitations and challenges of satellite-derived SSS are then discussed. The errors from the retrieval algorithms, discrepancies in the spatio-temporal scales of in situ and remote sensing, and limitations of the satellite-derived SSS are then detailed. Finally, our paper provides suggestions for the future directions of SSS remote sensing in five ways: mitigation of measurement errors, improvement of currently available SSS products, enhancement of the usage of in situ data, reconstruction of three-dimensional salinity information, and synergetic uses of multi-satellite missions.
Sizes of Passively Evolving Galaxies at z ~2 in CLASH

Abstract We select ten passively evolving and massive galaxies at redshift z ~ 2 from the Cluster Lensing And Supernova survey with Hubble (CLASH). We derive the stellar properties of these galaxies using the multiwavelength HST WFC3 and ACS data, together with Spitzer IRAC observations. We also analyze the optical rest-frame morphology of these high redshift objects by using the GALFIT package (Peng et al. 2002). The observed near-IR images, obtained with the HST/WFC3 camera with high spatial resolution and amplified by the foreground clusters, provide us with a good chance to study the structures of such systems. Six out of ten galaxies have on average a four times smaller effective radius, in agreement with previous works at redshift z ~ 2.
Magnetic Force Performance of Hybrid Multisurface HTS Maglev System With Auxiliary Onboard PMs

The vertical levitation force, guidance force, and magnetic stiffness values, and thus the loading capacity and movement stability of high-temperature superconducting (HTS) Maglev systems, are aimed to be increased in this study by using auxiliary permanent magnets (PMs) in the onboard unit together with the multisurface HTS-permanent magnetic guideway (PMG) arrangement (hybrid multisurface arrangement). First, the magnetic levitation force, guidance force, and stiffness performances of the hybrid multisurface arrangement were investigated at different field cooling heights (FCH). Then, to compensate for the negation of instability that results from the higher repulsive force between the onboard PMs and the PMG and to obtain an optimal magnetic field medium, we have changed the vertical position of the auxiliary onboard PMs (ZPM) to ZPM = 0, 2, and 4 mm, at the cost of a bit of adecrement in the vertical levitation force. The bigger levitation force, together with the guidance force values for FCH = 25 mm and ZPM = 0 mm, indicates that the hybrid multisurface HTS–PMG arrangements are beneficial to increasing the practical applicability of Maglev systems.

The ray theory of ship waves and the class of streamlined ships

A new theory is given for calculating the wave pattern and wave resistance of a ship moving at low Froude number F. It applies to ships of any width, either full-bodied or slender. In this theory, the waves travel along rays which start at source points, such as the bow and stern, on the water-line. They propagate with the speed of waves in deep water, but are also advected by the double body flow. This is the flow about the ship and its image in the undisturbed free surface. The phase of a wave at any point on a ray is the optical length of the ray from the source to that point. The amplitude is determined by an excitation coefficient, which determines its initial value, and by an integral along the ray. The total wave height at any point is the sum of the heights on all the rays through the point. The theory is incomplete because the excitation coefficients are known only for thin ships. As an illustration, the theory is applied to the thin ship case, and the results then agree with Michell's thin ship solution evaluated for F small. A new class of ships, which we call streamlined ships, is introduced next. The usual linear free surface condition applies to the waves they produce. The ray theory is developed for these waves at low F, and it involves straight rays produced at all points on the rear half of the water-line. In addition, as an alternative to the ray theory, another method is presented for obtaining the waves at low F. It involves a Schrödinger-like equation in which distance along the ship's centre-line is the time-like co-ordinate.
Large Integral Points on Elliptic Curves

To ml, friend Dan Shanks Abstract. We describe several methods which permit one to search for big integral points on certain elliptic curves, i.e., for integral solutions (x, ,') of certain Diophantine equations of the form V2 = X3 + ax + b (a, b E Z) in a large range Ixi, Iy I < B, in time polynomial in loglogB. We also give a number of individual examples and of parametric families of examples of specific elliptic curves having a relatively large integral point.
The Role of Cognitive Deficits in Borderline Personality Disorder with Early Traumas: A Mediation Analysis

(1) Background: although studies of cognitive functions are still limited in borderline personality disorder (BPD), the initial evidence suggested that BPD patients have deficits of executive functions and social cognition. In addition, patients who report physical and psychic traumatic experiences in childhood and adolescence show considerable neurocognitive impairment and severe BPD symptoms. The present study has a twofold aim: (1) to evaluate the differences in neurocognitive performances between BPD patients and healthy controls and (2) to verify in the BPD patients group whether neurocognitive deficits have the role of mediating the effect of early traumas on BPD psychopathology. (2) Methods: 69 subjects were enrolled: 38 outpatients with a diagnosis of BPD (DSM-5) and 31 healthy controls. BPD patients were tested with the Borderline Personality Disorder Severity Index (BPDSI), and the Childhood Trauma Questionnaire–Short Form (CTQ-SF). All subjects were evaluated with the Iowa Gambling task (IGT), the Berg card sorting test (BCST), the Tower of London task (ToL), and the Reading-the-mind-in-the-eyes-test (RMET). Statistical analysis was performed with the analysis of variance to compare the cognitive performances between BPD patients and controls. A mediation analysis was conducted with the Sobel Test in the BPD patients group. The significance level was p ≤ 0.05. (3) Results: significant differences between the two groups were found for several parameters of all the cognitive tests examined: BCST, IGT, ToL, and RMET. Mediation analysis with the Sobel test demonstrated that the percentage of correct answers in the BCST (BCSTc) and the RMET score significantly mediated the relation between the CTQ total score and BPDSI total score. (4) Conclusions: BPD patients showed an impairment of the following executive functions: set shifting, decision making, planning and problem solving, and social cognition abilities, in comparison with controls. Our results suggested that the effect of early trauma on BPD psychopathology was mediated by a deficit in two cognitive domains: cognitive flexibility and social cognition.
Atomic force microscope with magnetic force modulation

We have constructed a scanned stylus atomic force microscope (AFM) with direct force modulation and integrated microfluorescence optics. The instrument was designed to image the surface of massive samples under various ambient conditions. In force modulation microscopy the imaging force is modulated during the scanning process via an external magnetic field that acts directly on the magnetic AFM tip. Polymeric Langmuir–Blodgett films on silicon oxide were imaged to evaluate the application range of the instrument. We demonstrate that direct force modulation microscopy permits the quantitative recording of the local complex compliance both as a function of the location and as a function of the frequency. In a novel imaging mode referred to as sample resonance mode, the contrast of the image can be selectively enhanced based on local elasticity differences.
Redox-Dependent Modulation of Human Liver Progenitor Cell Line Fate

Redox homeostasis is determinant in the modulation of quiescence/self-renewal/differentiation of stem cell lines. The aim of this study consisted of defining the impact of redox modifications on cell fate in a human hepatic progenitor line. To achieve this, the HepaRG cell line, which shows oval ductular bipotent characteristics, was used. The impact of redox status on the balance between self-renewal and differentiation of HepaRG cells was investigated using different methodological approaches. A bioinformatic analysis initially proved that the trans-differentiation of HepaRG toward bipotent progenitors is associated with changes in redox metabolism. We then exposed confluent HepaRG (intermediate differentiation phase) to oxidized (H2O2) or reduced (N-acetylcysteine) extracellular environments, observing that oxidation promotes the acquisition of a mature HepaRG phenotype, while a reduced culture medium stimulates de-differentiation. These results were finally confirmed through pharmacological modulation of the nuclear factor (erythroid-derived 2)-like 2 (NRF2), a principal modulator of the antioxidant response, in confluent HepaRG. NRF2 inhibition led to intracellular pro-oxidative status and HepaRG differentiation, while its activation was associated with low levels of reactive species and de-differentiation. In conclusion, this study shows that both intra- and extracellular redox balance are crucial in the determination of HepaRG fate. The impact of redox status in the differentiation potential of HepaRG cells is significant on the utilization of this cell line in pre-clinical studies.
Influence of the temperature of the active medium on the stimulated emission characteristics of an Sr–He recombination laser

The maximum attainable average output power of an Sr–He recombination laser (λ = 430.5 nm) was ~ 14 W/m limited by overheating of the active medium. An average output power of 3.9 W at a pulse repetition frequency of 29 kHz was obtained using a water-cooled laser tube 33-cm long and 1 cm in diameter.
ICA-CNN: Gesture Recognition Using CNN With Improved Channel Attention Mechanism and Multimodal Signals

As a promising technology in human–computer interface (HCI), deep learning has good application prospects for gesture recognition from surface electromyography (sEMG) signals. However, mainstream network structures with satisfactory recognition accuracy are too complex to be deployed on edge devices. The lightweight neural network tends to have difficulty in fulfilling the requirement of recognition accuracy with limited computing power. In order to make the neural network adapt to different applications as much as possible, we propose a flexible and modular method based on sEMG and acceleration signals for gesture recognition. Moreover, a lightweight convolutional neural network with the improved channel attention mechanism (ICA-CNN) can achieve satisfactory performance in recognition accuracy or inference speed for different applications. The experimental results show that the recognition accuracy of the proposed method on 49 gestures is 94.24% using sEMG and acceleration signals, much higher than the accuracy of the method only using sEMG signals. In addition, the single inference of the proposed method takes only 38.6 ms on the CPU.
Two-Body Charmless Baryonic B Decays at LHCb

The potential of the LHCb experiment to make the rst discovery of a two-body charmless baryonic B decay is explored. The most promising channel is B 0 ! p p, for which a 5 discovery is possible with around 0.25 fb 1 of LHCb data at nominal centre-of-mass energy, assuming that the value for the B 0 ! p p branching ratio is close to the current experimental upper limit. LHCb also has prospects for other two-body charmless baryonic B decays, such as Bs! p p and decays involving a .
