Multi-Scale Fusion Uncrewed Aerial Vehicle Detection Based on RT-DETR

Field: Computer Science (Physical Sciences)

With the rapid development of science and technology, uncrewed aerial vehicle (UAV) technology has shown a wide range of application prospects in various fields. The accuracy and real-time performance of UAV target detection play a vital role in ensuring safety and improving the work efficiency of UAVs. Aimed at the challenges faced by the current UAV detection field, this paper proposes the Gathering Cascaded Dilated DETR (GCD-DETR) model, which aims to improve the accuracy and efficiency of UAV target detection. The main innovations of this paper are as follows: (1) The Dilated Re-param Block is creatively applied to the dilatation-wise Residual module, which uses the large kernel convolution and the parallel small kernel convolution together and fuses the feature maps generated by multi-scale perception, greatly improving the feature extraction ability, thereby improving the accuracy of UAV detection. (2) The Gather-and-Distribute mechanism is introduced to effectively enhance the ability of multi-scale feature fusion so that the model can make full use of the feature information extracted from the backbone network and further improve the detection performance. (3) The Cascaded Group Attention mechanism is innovatively introduced, which not only saves the computational cost but also improves the diversity of attention by dividing the attention head in different ways, thus enhancing the ability of the model to process complex scenes. In order to verify the effectiveness of the proposed model, this paper conducts experiments on multiple UAV datasets of complex scenes. The experimental results show that the accuracy of the improved RT-DETR model proposed in this paper on the two UAV datasets reaches 0.956 and 0.978, respectively, which is 2% and 1.1% higher than that of the original RT-DETR model. At the same time, the FPS of the model is also improved by 10 frames per second, which achieves an effective balance between accuracy and speed.
On optimal service differentiation in congested network markets

Field: Decision Sciences (Social Sciences)

As Internet applications have become more diverse in recent years, users having heavy demand for online video services are more willing to pay higher prices for better services than light users that mainly use e-mails and instant messages. This encourages the Internet Service Providers (ISPs) to explore service differentiations so as to optimize their profits and allocation of network resources. Much prior work has focused on the viability of network service differentiation by comparing with the case of a single-class service. However, the optimal service differentiation for an ISP subject to resource constraints has remained unsolved. In this work, we establish an optimal control framework to derive the analytical solution to an ISP's optimal service differentiation, i.e., the optimal service qualities and associated prices. By analyzing the structures of the solution, we reveal how an ISP should adjust the service qualities and prices in order to meet varying capacity constraints and users' characteristics. We also obtain the conditions under which ISPs have strong incentives to implement service differentiation and whether regulators should encourage such practices.
Reliable sensors based on graphene textile with negative resistance variation in three dimensions

Field: Materials Science (Physical Sciences)

The weft-knitted reduced graphene oxide (r-GO) textile that is made up of many conductive r-GO coated fibers was successfully prepared dependent on the electrospray deposition technique. Interestingly, the r-GO textile presents negative resistance variation not only in axial direction as the pressure increases but also in transverse direction as the lateral stretch increases which makes it has the advantage to fabricate the reliable sensors based on strain-resistance effect. The transverse-strain and pressure sensors based on the r-GO textiles all show the excellent sensing characteristics such as high sensitivity, reliability, and good durability, etc. The maximum gauge factors (GF) of the transverse-sensor are 27.1 and 153.5 in the x- and y-direction, respectively. And the practical detection range can up to 40% in the x-direction and 35% in the y-direction, respectively. The r-GO textile pressure sensor also shows high sensitivity for a broad pressure range that with a GF up to 716.8 kPa−1 for less than 4.5 kPa region and still has more sensitive pressure sensing characteristics even the pressure goes up to 14 kPa. Based on those good performances of r-GO textile sensors, its potential applications in human body states monitoring have been studied.
Ex Anthropos: Implications of the Creation of the ‘Posthuman’ for the (Created) ‘Human’

Field: Arts and Humanities (Social Sciences)

The creation of the ‘posthuman’ impels us to (re)discover what is essentially human; thus our very species, or at least the narratives that comprise it, is at stake. Here, I will develop a theological response to the challenge of the posthuman, ultimately contending that the scientists designing the posthuman overstep creaturely boundaries. This uncouples the link between humanness and creatureliness, and although some try to absorb such statements into the nature of humanness, positing that to be human is to progress and enhance, I shall demonstrate that where the posthuman is concerned, unlike with transhumanism, these tenets are self-defeating. The posthuman surpasses us, yet simultaneously it is projected out of our humanocentric world, ex anthropos. It is deployed as the ‘other’ that allows us to reaf?rm our creatureliness, which the posthuman, as not created ex nihilo, does not share in.
The Lib-Lab Pact: A Parliamentary Agreement, 1977-78

Field: Social Sciences (Social Sciences)

The Lib-Lab Pact examines the only formal cross-party understanding at Westminster between 1945-2010. Through the use of archival sources and unique interviews with key participants, this study brings new insights into how an agreement, short of a full coalition, came about, how it was administered, and how it impacted on both political parties. Jonathan Kirkup investigates the particular turn of events in 1977 which led to a Pact between Prime Minister, James Callaghan, and Liberal Party leader, David Steel. A review of the negotiating process reveals, for the first time, that David Steel might have achieved more policy concessions, specifically on electoral reform. This volume explores the intra-party conflict which ensued in the Liberal Party, ultimately threatening the position of Steel as leader, as policy objectives were not realized. The legacy of the Pact is assessed, and how it influenced the strategy of the Liberal Party and Liberal Democrat politicians for the next thirty years.
Junction temperature measurement of GaN-based light-emitting diodes using temperature-dependent resistance

Field: Physics and Astronomy (Physical Sciences)

A simple and reliable method to determine the junction temperature of GaN-based light-emitting diodes (LEDs) is presented in this paper. The variation of resistance of doped GaN with temperature is advantageously used to measure junction temperature. A simple calibration relating to temperature and resistance is measured and shows excellent agreement with the model analysis. The junction temperature of the pulsed-driving LEDs is measured by resistance meter and shows good agreement with that by the forward voltage method. Experimental results obtained by the described method are presented and discussed. The temperature-dependent resistance method has potential to be a very useful alternative for measurement of temperature in electronic and optoelectronic devices.
Individuality-Preserving Gait Pattern Prediction Based on Gait Feature Transitions

Field: Computer Science (Physical Sciences)

This paper proposes a method for predicting individuality-preserving gait patterns. Physical rehabilitation can be performed using visual and/or physical instructions by physiotherapists or exoskeletal robots. However, a template-based rehabilitation may produce discomfort and pain in a patient because of deviations from the natural gait of each patient. Our work addresses this problem by predicting an individuality-preserving gait pattern for each patient. In this prediction, the transition of the gait patterns is modeled by associating the sequence of a 3D skeleton in gait with its continuous-value gait features (e.g., walking speed or step width). In the space of the prediction model, the arrangement of the gait patterns are optimized so that (1) similar gait patterns are close to each other and (2) the gait feature changes smoothly between neighboring gait patterns. This model allows to predict individuality-preserving gait patterns of each patient even if his/her various gait patterns are not available for prediction. The effectiveness of the proposed method is demonstrated quantitatively. with two datasets.
Serologic response to treatment of infectious syphilis. Ann Intern Med 114:1005–1009

Field: Medicine (Health Sciences)

Objective: To evaluate the serologic response to treatment of patients with infectious syphilis. Design: Historical cohort study of all cases of infectious syphilis in Alberta from 1981 to 1987. Patients: A total of 1090 patients were entered; 857 with primary syphilis, 183 with secondary syphilis, and 50 with early latent disease. Two hundred and eight patients were excluded who either were pregnant, had negative serologic results before treatment, had clinical relapse, were treatment failures, or were lost to follow-up. Interventions: All 882 evaluable patients were treated with a recommended antibiotic regimen for infectious syphilis and re-turned for re-assessment including repeat serologic testing. Measurements and Main Results: Seventy-two percent (95 % CI, 66 % to 77%) and 56 % (CI, 43 % to 70%) of patients with initial episodes of primary or secondary syphilis had seroreverted accord-ing to rapid plasma reagin (RPR) test results by 36 months. A 2-and 3-tube decline was seen by 6 and 12 months in primary and secondary syphilis. Early latent syphilis resulted in only a 2-tube decrease at 12 months. Serologic response was not affected by sex, age, race, or sexual orientation. Patients with their first infection were more likely to experience RPR seroreversal than those with repeat infections. The RPR reversal rates also depended on the pretreatment titer and stage of disease. At 36 months, 24 % (CI, 20 % to 28%) of patients had nonreactive fluorescent treponemal antibody absorption tests (FTA-Abs), and 13 % (CI, 11 % to 15%) had nonreactive microhemoglutination tests for Treponema palli-dum (MHA-TP). Conclusions: Adequate therapeutic response for syphilis must be based on illness episode and the pretreatment RPR titer. Trepone-mal tests can demonstrate seroreversion after 36 months, and a negative treponemal test does not rule out a past history of syphilis.
Prevalence of Bone Mineral Disease in Children with Acute Kidney Disease on Continuous Renal Replacement Therapy: A Case Control Study

Field: Medicine (Health Sciences)

Abstract

Background Continuous kidney replacement therapy (CKRT) with regional citrate anticoagulation (RCA) is preferred in critically ill children with acute kidney disease (AKD). It is unclear whether CKRT exacerbates risk of bone mineral disease in AKD. We designed a case-control study to evaluate osteopenia and mineral balance markers in prolonged CKRT with RCA compared to prolonged immobilization. Methods Cases were AKD patients on CKRT with RCA and controls immobilized ≥ 28 days, matched with propensity scoring. Data collected at day 0, 14 and 28. Two blinded radiologists independently evaluated for osteopenia/fractures; reliability assessed by kappa statistics. Results Osteopenia in cases higher at day 14 (20/53 cases v/s 10/49 controls, p 0.05), and at day 28 (21/53 cases v/s 11/49 controls, p 0.06). Younger age, CKRT, gastrointestinal/liver comorbidity increased odds of osteopenia in cases and controls. Citrate rate adjusted for blood flow had higher odds of day 28 osteopenia. New fractures higher in cases (13/53) than controls (3/49) (p 0.01). Younger age, osteopenia at baseline, day 14, and 28 had higher odds of fractures in cases. Radiologist agreement for osteopenia was moderate (Kappa 0.62). Conclusions This is the first comparative study in children with AKD on prolonged CKRT and bone complications. Increased fractures and osteopenia noted in children undergoing prolonged CKRT compared to immobilization. Increased risk of fractures associated with presence/persistence of osteopenia and younger age. Increased osteopenia on CKRT suggested factors beyond immobilization, like age, anticoagulation, metabolic demands, dialytrauma, baseline osteopenia, hyperparathyroidism, and underlying primary disease, may play a significant role.
A proposal for improving safety in construction projects by strengthening coordinators’ competencies in health and safety issues

Field: Social Sciences (Social Sciences)

The figure of the coordinator in health and safety issues in the construction sector first appeared in our legislation through the incorporation of the European Directives (in our case Royal Decree 1627/97 on the minimum health and safety regulations in construction works), and is viewed differently in different countries of the European Union regarding the way they are hired and their role in the construction industry.\n\n\t\t\t\t Coordinating health and safety issues is also a management process that requires certain competencies that are not only based on technical or professional training, but which, taking account of the work environment, require the use of strategies and tools that are related to experience and personal skills. Through a piece of research that took account of expert opinions in the matter, we have found which competencies need to be possessed by the health and safety coordinator in order to improve the safety in the works they are coordinating. The conclusions of the analyses performed using the appropriate statistical methods (comparing means and multivariate analysis techniques), will enable training programmes to be designed and ensure that the health and safety coordinators selected have the competencies required to carry out their duties.
Vestibulo-autonomic control in man: Short- and long-latency vestibular effects on cardiovascular function

Field: Neuroscience (Life Sciences)

We examined the hypothesis that vestibular signals may exert a rapid control on the heart adjusting cardiovascular function to maintain homoestasis during changes in body posture. Short- and long-latency effects of vestibular stimulation on heart rate (HR), systolic blood pressure (SP), diastolic pressure (DP) and digital blood flow (BF) were studied in fourteen normal controls (NC) and nine labyrinthine-defective subjects (LDS) exposed to abrupt head accelerations. Subjects lay supine with their head suspended in a sling whose 'release' was triggered at delays of 170 ms and 570 ms after an R-spike of the ECG. Release caused the head to fall with an acceleration ∼0.8 g for approximately 140 ms. Three additional NC underwent head drops at 170 ms, 370 ms, 470 ms and 570 ms to determine response latencies with precision. In NC, the short-latency response to head drops timed 170 to 470 ms after an R-spike was to shorten the time to the next R-spike in comparison to pre-drop heartbeat cycles. Drops at 570 ms delay shortened only the succeeding post-stimulus RR-interval. In LDS, head drops timed 170 ms after a heartbeat failed to shorten the ongoing cardiac cycle. For both delays only the succeeding cardiac cycle was significantly shortened. In all subjects, SP rose slightly by approximately 1–3% and BF decreased by 7–24% after 3–4 heartbeats post-drop. The results are evidence for an excitatory vestibulo-cardiac reflex in man which accelerates heart rate at a latency circa 500–600 ms. SP and BF are affected at longer latencies of several heart beats. A delayed increase of heart rate in response to postural challenge may contribute to the autonomic distress experienced by patients with vestibular loss.

Assessment of Placental Extracellular Vesicles-Associated Fas Ligand and TNF-Related Apoptosis-Inducing Ligand in Pregnancies Complicated by Early and Late Onset Preeclampsia

Field: Medicine (Health Sciences)

Preeclampsia (PE) is a hypertensive disorder that affects 2-8% of pregnancies and is one of the main causes of fetal, neonatal, and maternal mortality and morbidity worldwide. Although PE etiology and pathophysiology remain unknown, there is evidence that the hyperactivation of maternal immunity cells against placental cells triggers trophoblast cell apoptosis and death. It has also been reported that placenta-derived extracellular vesicles (EV) carry Fas ligand (FasL) and Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and trigger apoptosis in Jurkat T cells. This study aimed to quantify and compare FasL and TRAIL expression in EV derived from cultures of placenta explants from women with PE (early versus late) and women with uncomplicated pregnancies. Also, the study assessed EV capacity to induce apoptosis in Jurkat T cells. The authors isolated EV from placenta explant cultures, quantified FasL and TRAIL using ELISA, and analyzed EV apoptosis-inducing capability by flow cytometry. Results showed increased FasL and TRAIL in EV derived from placenta of women with PE, and increased EV apoptosis-inducing capability in Jurkat T cells. These results offer supporting evidence that EV FasL and TRAIL play a role in the pathophysiology of PE.
Episodic nausea and abdominal sensations as sole manifestations of simple partial seizures.

Field: Medicine (Health Sciences)

In adults, seizures manifesting with abdominal complaints are usually associated with complex partial or secondary generalized seizures. Also, seizure periodicity is not expected in postmenopausal women. We encountered a 72-year-old woman with episodic nausea and abdominal pain that usually occurred with predictable regularity. When symptoms persisted after extensive gastrointestinal investigations and cholecystectomy, she was referred to us and the diagnosis of simple partial seizures was suspected. Both EEG and brain MRI were normal. The diagnosis was established by video/EEG monitoring, which recorded several typical clinical events associated with right temporal ictal discharges. Because treatment with several antiepileptic medications caused intolerable side effects, the patient is now maintained on a low dose of Lamotrigine, which reduced seizure frequency and severity. This patient demonstrates that `abdominal` complaints, although rare, may be the sole manifestation of simple partial seizures. Unless considered in the differential diagnosis, the patient may undergo unnecessary and potentially harmful procedures.
The role of forensic investigation in systemic risk enquiry: Reflections from case studies of disasters in Istanbul, Kathmandu, Nairobi, and Quito

Field: Social Sciences (Social Sciences)

The systemic nature of risk is increasingly acknowledged within scholarship, policy and practice relating to disaster management. However, a number of conceptual and methodological challenges arise in advancing empirical inquiry in this regard. These challenges relate to how the boundaries of the system are determined both spatially and temporally, how expertise from across disciplines is integrated to allow for consideration of institutional and broad socio-economic drivers of risk in addition to physical drivers, and, crucially, how causality operates within system complexity. The potential of forensic investigations of disasters that typically deploy in-depth case studies to overcome these obstacles is evaluated on the basis of causal mapping with experts from a range of disciplinary backgrounds in Istanbul, Kathmandu, Nairobi and Quito. It is found that such investigations can serve to interrogate the fundamental value of any given system and its spatial and temporal bounds, generate collective mental models of the system from which risk emerges, and drive reflection on its root causes. However, it is critical that forensic investigation approaches carefully consider participant selection and facilitation in order to effectively operationalise the systemic risk concept in complementarity with other approaches.
