Cold-based glaciation of Pavonis Mons, Mars: evidence for moraine deposition during glacial advance
Authors: Parsons Reid A. , Kanzaki Tomohiro , Hemmi Ryodo , Miyamoto Hideaki 
Published: March 2020

AbstractThe three large volcanoes in the Tharsis region of Mars: Arsia, Pavonis, and Ascraeus Montes all have fan-shaped deposits (FSDs) on their northern or western flanks consisting of a combination of parallel ridges, knobby/hummocky terrain, and a smooth, viscous flow-like unit. The FSDs are hypothesized to have formed in the Amazonian during a period of high spin-axis obliquity which redistributed polar ice to the equatorial Tharsis region resulting in thick (> 2 km), flowing ice deposits. Based on previous ice flow simulations and crater surveys, the ridges are interpreted to be recessional drop moraines formed as debris on the ice sheet surface was transported to the ice margin—forming a long ridge sequence over an extended (∼100 Myr) period of ice sheet retreat. We test this hypothesis using a high-resolution, thermomechanical ice sheet model assuming a lower ice loss rate (~ 0.5 mm/year) than prior work based on new experimental results of ice sublimation below a protective debris layer. Our ice flow simulation results, when combined with topographic observations from a long sequence of ridges located interior of the Pavonis FSD, show that the ridged units were more likely deposited during one or more periods of glacial advance (instead of retreat) when repetitive pulses (approx. 120 kyr periodicity) of ice accumulation during high obliquity produced kinematic waves which advected a large volume of surface debris to the ice margin. If ridge deposition does occur during glacial advance, it could explain the cyclic pattern of ridge spacing and would link the dominant, 120 kyr periodicity in obliquity to the time interval between adjacent ridges. By measuring the spacing between these ridges and applying this timescale, we constrain the velocity of glacial margin to be between 0.2 and 4 cm/Earth year—in close agreement with the numerical simulation. This re-interpretation of the FSD ridged unit suggests that the timescale of FSD formation (and perhaps the duration of the Amazonian high obliquity period) was shorter than previously reported.

Abstract
Background
Medication is an important approach of treatment for patients with schizophrenia; however, the availability of visiting nurses and other human-related support is limited. This study aims to build a system in which service robots support the treatment of individuals with schizophrenia with medication at home. Moreover, medical staff can seamlessly monitor the status of their patients through the robots using this system. In this study, to develop a support system, interactions between a communication robot and patients were surveyed, with a focus on the patients’ impression of the robot and actual utterance times.

Methods
Communication between a commercially available communication robot and schizophrenic patients was investigated, particularly the participants’ feelings about the robot. In addition, the utterance data between the participants and the robot were extracted and the durations of the conversations were assessed.

Results
The examined interaction mode of a robot (talkative or not talkative) and whether the participant spoke or not (spoke or did not speak) revealed no significant association in all adjectives. A co-occurrence network graph showed differences in the participants’ impressions of the robot depending on how talkative the robot was. That is, when the robot did not initiate conversation often, the patient was more likely to initiate interactions and use longer phrases than when the robot initiated conversation frequently. Conversations also lasted longer when the participant, not the robot, initiated conversation.

Conclusions
People with schizophrenia converse with a robot regardless of whether the robot is talkative or not. Since the content of the conversation was not analyzed qualitatively, it is necessary to carefully examine whether people with schizophrenia can develop partnerships with robots.
Dexterous object manipulation by a multi-fingered robotic hand with visual-tactile fingertip sensors
Authors: Choi Seung-hyun , Tahara Kenji 
Published: March 2020

AbstractIn this paper, a novel visual-tactile sensor is proposed; additionally, an object manipulation method for a multi-fingered robotic hand grasping an object is proposed by detecting a contact position using the visual-tactile sensor. The visual-tactile sensor is composed of a hemispheric fingertip made of soft silicone with a hollow interior and a general USB camera located inside the fingertip to detect the displacement of the many point markers embedded in the silicone. The deformation of each point marker due to a contact force is measured, and a contact position is estimated reliably through a novel method of creating virtual points to determine the point clouds. The aim is to demonstrate both the estimation performance of the new visual-tactile sensor and its usefulness in a grasping and manipulation task. By using the contact position obtained from the proposed sensor and the position of each fingertip obtained from kinematics, the position and orientation of a grasped object are estimated and controlled. The effectiveness of the method is illustrated through numerical simulation and its practical use is demonstrated through grasping and manipulating experiments.
Delineating forest stands from grid data
Authors: Pukkala Timo 
Published: March 2020

Abstract
Background
Forest inventories are increasingly based on airborne laser scanning (ALS). In Finland, the results of these inventories are calculated for small grid cells, 16 m by 16 m in size. Use of grid data in forest planning results in the additional requirement of aggregating management prescriptions into large enough continuous treatment units. This can be done before the planning calculations, using various segmentation techniques, or during the planning calculations, using spatial optimization. Forestry practice usually prefers reasonably permanent segments created before planning. These segments are expected to be homogeneous in terms of site properties, growing stock characteristics and treatments. Recent research has developed methods for partitioning grids of ALS inventory results into segments that are homogeneous in terms of site and growing stock characteristics. The current study extended previous methods so that also the similarity of treatments was considered in the segmentation process. The study also proposed methods to deal with biases that are likely to appear in the results when grid data are aggregated into large segments.

Methods
The analyses were conducted for two datasets, one from southern and the other from northern Finland. Cellular automaton (CA) was used to aggregate the grid cells into segments using site characteristics with (1) growing stock attributes interpreted from ALS data, (2) predicted cutting prescriptions and (3) both stand attributes cutting prescriptions. The CA was optimized for each segmentation task. A method based on virtual stands was used to correct systematic errors in variable estimates calculated for segments.

Results
The segmentation was rather similar in all cases. The result is not surprising since treatment prescriptions depend on stand attributes. The use of virtual stands decreased biases in growth prediction and in the areas of different fertility classes.

Conclusions
Automated stand delineation was not sensitive to the type of variables that were used in the process. Virtual stands are an easy method to decrease systematic errors in calculations.

AbstractIn 2018, our team collected aerosols samples from five poultry farms in Malaysia. Influenza D virus was detected in 14% of samples. One sample had an 86.3% identity score similar to NCBI accession number MH785020.1. This is the first molecular sequence of influenza D virus detected in Southeast Asia from a bioaerosol sample. Our findings indicate that further study of role of IDV in poultry is necessary.
Epilepsy surgery for refractory seizures: a systematic review and meta-analysis in different complications
Authors: Joudi Mashhad Maryam , Harati Hadi , Parooie Fateme , Salarzaei Morteza 
Published: March 2020

Abstract
Background
Nearly one-third of epilepsy patients are refractory/resistant to medical treatment. Developments made in surgical techniques have significantly increased the effectiveness and safety of these techniques, as such techniques have been demonstrated to improve seizure control/freedom outcomes.

Objectives
The aim of this systematic review and meta-analysis was to evaluate the complications of epilepsy surgery.

Patient and methods
The searches were conducted by three independent researchers to find the relevant studies published from January 1, 2009, until the end of January 6, 2019. For English published statistical studies, all studies conducted on epileptic patients who have undergone epilepsy surgery were included.

Statistical analysis
A meta-analysis was conducted in the STATA14 statistical software.

Results
A total of 6735 patients with epilepsy who had undergone the epilepsy surgery were studied. The overall prevalence of complications was 5%. The prevalence of major and minor complications was 5.4% and 3.2% respectively. The prevalence of complications related to the temporal epilepsy surgery and the extra-temporal epilepsy surgery based on 3 studies was 7.9% and 8.2 % respectively. The frequency of neurological and surgical complications after epilepsy surgery was 4.4% and 4.1% respectively.

Conclusion
The overall rate of complications caused by epilepsy surgery was reasonably low (5%), implying that epilepsy surgery especially temporal lobe resection can be safe preferably when performed by an experienced surgeon.
The effect of scale in quantifying fire impacts on species habitats

Published: March 2020

AbstractBackgroundFire size and severity have increased in the western United States in recent decades, and are expected to continue to increase with warming climate. Habitats for many species are threatened by large and high-severity fires, but the effect of spatial scale on the relationship between fires and habitat modifications is poorly understood. We used the 2011 Wallow Fire—the largest wildfire in the state history of Arizona, USA—as a case study and assessed changes in predicted nesting habitat of the threatened Mexican spotted owl (Strix occidentalisXántus de Vésey) in the first three years following the fire. Our objective was to explore potential relationships between burn severity and changes in habitat suitability at different spatial scales. To accomplish this, we applied a multi-scale optimized habitat selection model to pre- and post-fire landscapes and compared the differences in predictions along a continuous scale gradient.ResultsFire effects on habitat quality were spatially variable and the strength and direction of relationships were scale-dependent. Spatial patterns of burn-severity mosaic resembled the patterns of habitat suitability change. High burn severity reduced nesting habitat suitability and this relationship was strongest at broad scales. Pre-fire habitat suitability was positively related to burn severity, again at fairly broad scales, but the relationship was weak. Low-severity fires had little effect on habitat suitability.ConclusionsMulti-scale analysis may influence the statistical measures of goodness of fit in assessing fire effects on species and their habitats. Future studies should explicitly address spatial scale when quantifying fire effects.

Published: March 2020

AbstractWith the rapid development of deep learning technology, behavior recognition based on video streams has made great progress in recent years. However, there are also some problems that must be solved: (1) In order to improve behavior recognition performance, the models have tended to become deeper, wider, and more complex. However, some new problems have been introduced also, such as that their real-time performance decreases; (2) Some actions in existing datasets are so similar that they are difficult to distinguish. To solve these problems, the ResNet34-3DRes18 model, which is a lightweight and efficient two-dimensional (2D) and three-dimensional (3D) fused model, is constructed in this study. The model used 2D convolutional neural network (2DCNN) to obtain the feature maps of input images and 3D convolutional neural network (3DCNN) to process the temporal relationships between frames, which made the model not only make use of 3DCNN’s advantages on video temporal modeling but reduced model complexity. Compared with state-of-the-art models, this method has shown excellent performance at a faster speed. Furthermore, to distinguish between similar motions in the datasets, an attention gate mechanism is added, and a Res34-SE-IM-Net attention recognition model is constructed. The Res34-SE-IM-Net achieved 71.85%, 92.196%, and 36.5% top-1 accuracy (The predicting label obtained from model is the largest one in the output probability vector. If the label is the same as the target label of the motion, the classification is correct.) respectively on the test sets of the HMDB51, UCF101, and Something-Something v1 datasets.

AbstractBackgroundWe have conducted a prospective cohort study with the aim of comparing operative time, intraoperative blood loss, and radiologic and clinical outcomes between imageless (NAVIO) and image-based (MAKO) robot-assisted unicompartmental knee arthroplasty (UKA) for medial compartment osteoarthritis (OA) of the knee.MethodsA total of 33 patients with medial compartment OA of the knee were prospectively allocated on alternate operative days of their surgery to MAKO (16 patients) or NAVIO (17 patients) robot-assisted UKA. The primary outcome (Knee Society Score [KSS] and Knee Functional Score [KFS]) and the secondary outcomes (intraoperative time of seven steps [registration of hip and ankle, femur and tibia, ligament tension, implant planning, preparation femur, tibia and trial implant], component alignment [coronal and sagittal of femur, tibia implant], blood loss, complications, and revision at 1 year after surgery) were compared between two groups. Statistical significance was set atP< 0.05.ResultsMean KSS measured at baseline and 1 year were, respectively, 70.3 (5.6) and 96.9 (5.7) in the NAVIO group and 72.3 (4.5) and 94.7 (10.01) in the MAKO group. Mean KFS measured at baseline and 1 year were, respectively, 95.5 (7.9) and 99.9 (0.25) in the NAVIO group and 67.3 (7.8) and 99.5 (1.2) in the MAKO group. There were no significant differences for KFS and KSS outcomes (P = 0.203 andP = 0.457, respectively) between the NAVIO and MAKO groups. Mean operative time and blood loss in the NAVIO versus MAKO robot-assisted UKA groups were 98 min versus 82.5 min and 136.3 ml versus 80 ml, respectively, and these differences were statistically significant. In the MAKO group, the intraoperative time was statistically significantly shorter in registration of hip and ankle center, femur and tibia, femur preparation, and trial implantation compared with the NAVIO group. There were no significant differences of component alignment and radiologic alignment at 1 year between the two groups. No perioperative or delayed complications (infection, periprosthetic fracture, thromboembolism, and compromised wound healing) and revisions were reported in either group.ConclusionsThis study demonstrated that two robotic systems showed no difference in clinical outcomes at 1 year and radiologic alignment of implants, whereas operative time and intraoperative blood loss were found to be less in MAKO robot-assisted UKA.Trial registrationClinicalTrials.gov,NCT03954912.

8505 Background: Routine surveillance imaging (RSI) for patients in complete remission from classical Hodgkin lymphoma (cHL) is common practice. RSI offers the theoretical benefit of detecting asymptomatic relapse, which may allow for more successful second-line therapy. Despite this, evidence for a clinical benefit of RSI is lacking. We compared outcomes in cHL patients undergoing RSI versus clinical surveillance (CS) in which scans are only obtained to evaluate concerning signs or symptoms. Methods: Patients with cHL diagnosed at three tertiary care centers from 2001-2010, who achieved complete remission (CR) following frontline therapy, were analyzed retrospectively. Patients were stratified into two groups based on the surveillance strategy employed. Baseline patient characteristics, prognostic features, treatment records, and outcomes were collected. The primary objective was to compare overall survival for patients undergoing RSI versus CS. As a secondary objective we compared the success of second-line therapy for relapsed patients in each group. Results: 207 patients met eligibility criteria, with 131 RSI patients and 76 CS patients. Patient characteristics (age, gender, stage, sedimentation rate, Hasenclever index, bulky disease and B symptoms) were similar in each group. Chemotherapy consisted of ABVD in 79% and Stanford V in 15%. Patients in the RSI group more commonly received ABVD (91% vs. 57%) and less often radiation therapy (38% vs. 68%). Mean number of scans was 4.77 in RSI and 1.11 in CS groups, respectively. With a median follow up of 4 years, the overall survival was similar in both groups (p=0.74), with 5 (3.8%) deaths in the RSI group and 4 (5.3%) in the CS group. Six (4.6%) relapses occurred in the RSI group (4 of which were detected by RSI), and 5 (6.6%) in the CS group (p=0.64 for relapse at 5 years). All relapsed patients achieved second CR with second-line therapy. Conclusions: RSI did not yield a survival advantage in cHL patients who achieved CR after frontline therapy.Given the radiation exposure, cost, and risk for additional procedures associated with RSI, we conclude CS is the preferred strategy in cHL patients in first complete remission.

8506 Background: Mogamulizumab (Moga), a defucosylated humanized anti-CCR4 antibody, was approved for the treatment of relapsed/refractory ATL in Japan in 2012. This multicenter, randomized, phase II trial was conducted to examine the efficacy of the combination of Moga with standard chemotherapy for untreated aggressive ATL. Methods: Previously untreated patients (pts) with CCR4-positive ATL were randomly assigned to receive mLSG15 plus Moga (arm A) or mLSG15 alone (arm B). The primary endpoint was CR rate (%CR), and secondary endpoints included ORR, PFS, OS and safety. Pts received 4 courses of mLSG15 regimen, with or without a total of 8 doses of Moga (1.0 mg/kg) once every 2 weeks. The planned sample size, 22 pts per arm, provided a probability of 80% that %CR in arm A would have larger %CR when true %CR for arm A is 15% better than that for arm B. Results: Of 54 pts randomized, 53 were treated (arm A: 29; arm B: 24). Male/female ratio was 53/47%, median age was 63 (37-81), and subtype was acute/lymphoma/unfavorable chronic, 70/25/6%. %CR and ORR in arms A and B was 52% (95%CI [CI]; 33, 71) vs. 33% (CI; 16, 55) and 86% (CI; 63, 96) vs. 75% (CI; 53, 90), respectively. The results in arm B were similar to the previously reported %CR of 40% and ORR of 72% with mLSG15 (Tsukasaki et al, JCO 2007). ORR according to the disease subtype, in arms A and B, was 55% vs. 29% for acute, 50% vs. 43% for lymphoma and 33% vs. 0% for unfavorable chronic. Median PFS was 259 days (CI; 197, -) for arm A and 192 days (CI; 147, -) for arm B. Median OS was not reached in both arms. The most common treatment-related AEs in each arm were neutropenia (100%, 96%), thrombocytopenia (100%, 96%), leukopenia (100%, 92%), lymphocytopenia (97%, 96%), anemia (97%, 92%) and febrile neutropenia (90%, 88%). In arm A, skin disorders were more frequent but manageable, and no serious skin disorder like Stevens-Johnson syndrome was observed. There was one treatment-related death, which was not related to Moga. Conclusions: The combination of Moga with mLSG15 was well tolerated and the study met its primary endpoint. These results suggest that Moga with mLSG15 is a rational treatment option for newly diagnosed aggressive ATL. Clinical trial information: NCT01173887.
