Patients with mild chronic obstructive pulmonary disease (COPD) demonstrate resting pulmonary vascular dysfunction as well as a blunted pulmonary diffusing capacity (DLCO) and pulmonary capillary blood volume (VC) response to exercise. The transition from the upright to supine position increases central blood volume and perfusion pressure, which may overcome microvascular dysfunction in an otherwise intact alveolar-capillary interface. The present study examined whether the supine position normalized DLCO and VC responses to exercise in mild COPD. Sixteen mild COPD participants and 13 age-, gender-, and height-matched controls completed DLCO maneuvers at rest and during exercise in the upright and supine position. The multiple [Formula: see text]-DLCO method was used to determine DLCO, VC, and membrane diffusion capacity (DM). All three variables were adjusted for alveolar volume (DLCOAdj, VCAdj, and DMAdj). The supine position reduced alveolar volume similarly in both groups, but oxygen consumption and cardiac output were unaffected. DLCOAdj, DMAdj, and VCAdj were all lower in COPD. These same variables all increased with upright and supine exercise in both groups. DLCOAdj was unaffected by the supine position. VCAdj increased in the supine position similarly in both groups. DMAdj was reduced in the supine position in both groups. While the supine position increased exercise VCAdj in COPD, the increase was of similar magnitude to healthy controls; therefore, exercise VC remained blunted in COPD. The persistent reduction in exercise DLCO and VC when supine suggests that pulmonary vascular destruction is a contributing factor to the blunted DLCO and VC response to exercise in mild COPD. NEW & NOTEWORTHY Patients with mild chronic obstructive pulmonary disease demonstrate a combination of reversible pulmonary microvascular dysfunction and irreversible pulmonary microvascular destruction.

Under investigation in this paper is a variable-coefficient AB (vcAB) system, which describes marginally unstable baroclinic wave packets in geophysical fluids and ultra-short pulses in nonlinear optics. The modulation instability analysis of solutions with variable coefficients in the presence of a small perturbation is studied. The modified Darboux transformation (mDT) of the vcAB system is constructed via a gauge transformation. The first-order non-autonomous rogue wave solutions of the vcAB system are presented based on the mDT. It is found that the wave amplitude of [Formula: see text] exhibits two types of structures, i.e. the double-peak structure appears if the plane-wave solution parameter [Formula: see text] is equal to zero, while selecting [Formula: see text] yields a single-peak one. Effects of the variable coefficients on the rogue waves are graphically discussed in detail. The periodic rogue wave and composite rogue wave are obtained with different inhomogeneous parameters. Additionally, the nonlinear tunneling of the rogue waves through a conventional hyperbolic nonlinear well and barrier are investigated.

Quantitative and qualitative running gait analysis allows the early identification and the longitudinal monitoring of gait abnormalities linked to running-related injuries. A promising calibration- and marker-less video sensor-based technology (i.e., Graal), recently validated for walking gait, may also offer a time- and cost-efficient alternative to the gold-standard methods for running. This study aim was to ascertain the validity of an improved version of Graal for quantitative and qualitative analysis of running. In 33 healthy recreational runners (mean age 41 years), treadmill running at self-selected submaximal speed was simultaneously evaluated by a validated photosensor system (i.e., Optogait—the reference methodology) and by the video analysis of a posterior 30-fps video of the runner through the optimized version of Graal. Graal is video analysis software that provides a spectral analysis of the brightness over time for each pixel of the video, in order to identify its frequency contents. The two main frequencies of variation of the pixel’s brightness (i.e., F1 and F2) correspond to the two most important frequencies of gait (i.e., stride frequency and cadence). The Optogait system recorded step length, cadence, and its variability (vCAD, a traditional index of gait quality). Graal provided a direct measurement of F2 (reflecting cadence), an indirect measure of step length, and two indexes of global gait quality (harmony and synchrony index). The correspondence between quantitative indexes (Cadence vs. F2 and step length vs. Graal step length) was tested via paired t-test, correlations, and Bland–Altman plots. The relationship between qualitative indexes (vCAD vs. Harmony and Synchrony Index) was investigated by correlation analysis. Cadence and step length were, respectively, not significantly different from and highly correlated with F2 (1.41 Hz ± 0.09 Hz vs. 1.42 Hz ± 0.08 Hz, p = 0.25, r2 = 0.81) and Graal step length (104.70 cm ± 013.27 cm vs. 107.56 cm ± 13.67 cm, p = 0.55, r2 = 0.98). Bland–Altman tests confirmed a non-significant bias and small imprecision between methods for both parameters. The vCAD was 1.84% ± 0.66%, and it was significantly correlated with neither the Harmony nor the Synchrony Index (0.21 ± 0.03, p = 0.92, r2 = 0.00038; 0.21 ± 0.96, p = 0.87, r2 = 0.00122). These findings confirm the validity of the optimized version of Graal for the measurement of quantitative indexes of gait. Hence, Graal constitutes an extremely time- and cost-efficient tool suitable for quantitative analysis of running. However, its validity for qualitative running gait analysis remains inconclusive and will require further evaluation in a wider range of absolute and relative running intensities in different individuals.

The detection of video piracy has improved and emerged as a popular issue in the field of digital video copyright protection because a sequence of videos often comprises a huge amount of data. The major difficulty in achieving efficient and simple video copy detection is to identify compressed and exclusionary video characteristics. To do this, we describe a video copy detection strategy that created the properties for a spatial-temporal domain. The first step is to separate each video sequence into the individual video frame, and then extract the boundaries of each video frame by using PCA SIFT and Hessian- Laplace. Next, for each video frame, we have to implement SVM and KNN features in the spatial and temporal domains to measure their performance matrices in the feature extraction. Finally, the global features found in the Video copy detection are accomplished uniquely and efficiently. Experiments arranged a commonly used VCDB 2014 video dataset, showing that result. The proposed approach is based on various copy detection algorithms and shows various features in terms of both accuracy and efficiency.

We analysed fluid dynamics at brain arteries having multiple inflow and out flow like Willis ring based on clinical imaging modalities. In addition, we analysed fluid dynamics with therapeutic devices like coils and stents to simulate their influences to blood flow. 3D CTA and MRA obtained three-dimensional structures of the brain vessels. The centreline was obtained from the three dimensional structure. Diameter of the blood vessels was measured by 3D CTA/MRA then smooth surfaced blood vessel models were created. For the fluid analysis, we developed a home brew software which can display parameters such as streamline, etc. In addition, our CFD (computational fluid dynamics) software can work in collaboration with a CAD (computer aided design) software which we also developed (VCAD: Volume CAD). So, therapeutic devices such as coils, balloons and stents could be placed in the models and CFD analysis could be performed placing devices in the models. The flow pattern in the complicated vascular structure could be calculated such as Willis ring which has multiple inputs like ICA, VA and multiple outlets like MCA and PCA with communicating arteries. CFD with therapeutic devices could also analysed with our system.

Objectives: To determine frequency of left main stem (LMS) and triple vessel coronary artery disease (3VCAD) in patients of Non-ST-elevation myocardial infarction (NSTEMI) and to compare the frequency of LMS and 3VCAD in patients with NSTEMI with or without ST elevation in lead aVR. Methodology: Total 346 patients with NSTEMI having age 30-70 years were included in this descriptive cross-sectional study. The data on demographic details was collected. All patients underwent electrocardiography (ECG) and cardiac specific troponin-I assessment. Patients were categorized as NSTEMI with or without ST-elevation in lead aVR. Coronary angiography was performed in all patients and angiographic findings were noted. Results: Mean age of patients was 51.87±10.03 years. There were 218 (63.01%) males and 128 (36.99%) female patients. 182 (52.60%) patients of NSTEMI had ST elevation in aVR. LMS disease was found in 53 (29.10%) patients with ST elevation in aVR. Sensitivity, specificity, positive predive value and negative predictive value of ST elevation in aVR for LMS disease was 62.35%, 50.57%, 29.12% and 80.49% respectively. 3 VCAD was found in 54 (29.70%) with ST elevation in aVR. Sensitivity, specificity, positive predive value and negative predictive value of ST elevation in aVR for 3VCAD was 77.14%, 53.52%, 29.67% and 90.24% respectively. Conclusion: NSTEMI patients with ST elevation in aVR may have higher chances of having LMS disease or 3VCAD. There is high negative predictive value for ST elevation in aVR to predict LMS disease or 3VCAD.

Purpose The purpose of this study is to expand on the existing literature by specifically examining data security incidents within the hospitality industry, assessing origins and causes, comparing breaches within the industry with those of other industries and identifying areas of concern. Design/methodology/approach A sample of data breach incidents is drawn from the Verizon VERIS Community Database (VCDB). Statistical comparisons between hospitality and non-hospitality industry firms are conducted following the Verizon A4 threat framework. Findings The results reveal that breaches between hospitality and non-hospitality firms differ significantly in terms of actors, actions, assets and attributes. Specifically, proportions of breaches in the hospitality industry are larger in terms of external actors, hacking and malware, user devices compromised and integrity violations. Additionally, compared to other industries, point-of-sales (POS) system breaches occur at a higher rate in the hospitality industry. The study finds that company size, hacking and malware predict the likelihood of a POS breach. Research limitations/implications The study uses secondary data and does not include the entire universe of data breaches. Originality/value In the quest to reduce data breach incidents, it is imperative to identify and assess the nature of data breach incidents between industries. Doing so permits the development of targeted industry-specific solutions rather than generic ones. This study systematically identifies differences between hospitality and non-hospitality data security incidents and then suggests areas where hospitality companies should focus future attention to mitigate breach incidents.

A haptic sensor coupled to a gamepad or headset is frequently used to enhance the sense of immersion for game players. However, providing haptic feedback for appropriate sound effects involves specialized audio engineering techniques to identify target sounds that vary according to the game. We propose a deep learning-based method for sound event detection (SED) to determine the optimal timing of haptic feedback in extremely noisy environments. To accomplish this, we introduce the BattleSound dataset, which contains a large volume of game sound recordings of game effects and other distracting sounds, including voice chats from a PlayerUnknown’s Battlegrounds (PUBG) game. Given the highly noisy and distracting nature of war-game environments, we set the annotation interval to 0.5 s, which is significantly shorter than the existing benchmarks for SED, to increase the likelihood that the annotated label contains sound from a single source. As a baseline, we adopt mobile-sized deep learning models to perform two tasks: weapon sound event detection (WSED) and voice chat activity detection (VCAD). The accuracy of the models trained on BattleSound was greater than 90% for both tasks; thus, BattleSound enables real-time game sound recognition in noisy environments via deep learning. In addition, we demonstrated that performance degraded significantly when the annotation interval was greater than 0.5 s, indicating that the BattleSound with short annotation intervals is advantageous for SED applications that demand real-time inferences.

Video copy localization aims to precisely localize all the copied segments within a pair of untrimmed videos in video retrieval applications. Previous methods typically start from frame-to-frame similarity matrix generated by cosine similarity between frame-level features of the input video pair, and then detect and refine the boundaries of copied segments on similarity matrix under temporal constraints. In this paper, we propose TransVCL: an attention-enhanced video copy localization network, which is optimized directly from initial frame-level features and trained end-to-end with three main components: a customized Transformer for feature enhancement, a correlation and softmax layer for similarity matrix generation, and a temporal alignment module for copied segments localization. In contrast to previous methods demanding the handcrafted similarity matrix, TransVCL incorporates long-range temporal information between feature sequence pair using self- and cross- attention layers. With the joint design and optimization of three components, the similarity matrix can be learned to present more discriminative copied patterns, leading to significant improvements over previous methods on segment-level labeled datasets (VCSL and VCDB). Besides the state-of-the-art performance in fully supervised setting, the attention architecture facilitates TransVCL to further exploit unlabeled or simply video-level labeled data. Additional experiments of supplementing video-level labeled datasets including SVD and FIVR reveal the high flexibility of TransVCL from full supervision to semi-supervision (with or without video-level annotation).

Background: The aim of our study was to evaluate the degree of genetic homozygosity in the group of patients with coronary artery disease (CAD), as well as to evaluate morphogenetic variability in CAD patients regarding the presence of investigated risk factors (RF) compared to a control sample of individuals. Additionally, we aimed to evaluate the distribution of ABO blood type frequencies between tested samples of individuals. Methods: This study analyzed individual phenotype and morphogenetic variability of 17 homozygously-recessive characteristics (HRC), by using HRC test in a sample of 148 individuals in CAD patients group and 156 individuals in the control group. The following RF were analyzed: hypertension, diabetes mellitus, hyperlipidemia, and smoking. Results: The mean value of HRC in CAD patients is significantly higher, while variability decreases compared to the control sample (CAD patients: 4.24 ± 1.59, control sample: 3.75 ± 1.69; VCAD-patients = 37.50%, VC = 45.07%). There is a significant difference in individual variations of 17 HRC between control sample and CAD patients (χ2 = 169.144; p < 0.01), which points out to different variability for tested genes. Mean values of HRC significantly differed in CAD patients in regard to the number of RF present. A blood type (OR = 1.75) is significant predictor for CAD, while O blood type (OR = 0.43) was significantly associated with controls. Conclusion: There is a higher degree of recessive homozygosity in CAD patients versus individuals in the control sample, and the presence of significant variations in the degree of recessive homozygosity as the number of tested RF increases.

Antecedentes: el duelo anticipado es el proceso por el que pasan algunas personas antes del fallecimiento de un ser querido o de que se confirme su muerte. Ocurre cuando varias circunstancias hacen prever que tarde o temprano un ser querido, como un familiar, una pareja o un amigo, va a morir. Objetivo: el objetivo de estudio fue conocer cuáles son las estrategias de afrontamiento al estrés y factores personales del cuidado y del cuidador que benefician o ponen en riesgo el duelo anticipado en cuidadores informales de personas de la tercera edad. Método: participaron 272 cuidadores informales. Se utilizó la Escala del Duelo en el Cuidador de Meichsner et al. (2016) y la Escala Breve de Afrontamiento al Estrés (COPE 28) de Carver (1997). Resultados: los resultados evidencian que el duelo anticipado es influenciado por el afrontamiento: el dolor emocional por el afrontamiento basado en apoyo (OR = .236), afrontamiento evasión a la emoción (OR = 3.751) y estar todo el día de cuidado (OR = 3.061). La pérdida emocional es estimada por el afrontamiento focalizado en el problema (OR = .201), cuando el cuidador es un adulto mayor (OR = .303) y por el medio tiempo de cuidado (OR = 2.029). La aceptación de la pérdida es influenciada por el afrontamiento focalizado al problema (OR = .172), afrontamiento evasión a la emoción (OR = 4.409), cuidador es adulto joven (OR = 2.361) y por el cuidado durante casi todo el día (OR = .536). Además, la pérdida absoluta se asoció con el afrontamiento focalizado en el problema (r = .249) y el afrontamiento de evasión con sustancias (r = .216). Conclusiones: este estudio logra identificar factores personales y tipos de afrontamiento al estrés que favorecen o disminuyen el duelo anticipado en el cuidador primario informal. Particularmente, la probabilidad de presentar dolor emocional aumenta de acuerdo al afrontamiento basado en el apoyo o el espiritual, pero disminuye con el afrontamiento basado en la evasión emocional y la mayor convivencia con el enfermo.

Introduction: Cervical artery dissection (CAD) involves the carotid (CCAD) or vertebral artery (VCAD). However, limited studies have compared their clinical features and outcomes. Our study utilized a comprehensive nationwide database to discern these differences. Method: We examined non-traumatic CAD-diagnosed patients from the U.S. National Inpatient Sample (2005-2019) using ICD-9 and ICD-10 codes. The evaluation included patient demographics, comorbidities, in-hospital complications, treatment, and costs. Differences between CCAD and VCAD were assessed using survey-weighted stepwise backward logistic regression, followed by propensity score matched adjusted regressions for outcomes. Result: From 2005 to 2019, we identified 157,086 CAD admissions, of which 79.9% (125,477) were spontaneous CADs, with CCAD outnumbering VCAD (67,671 vs. 57,806). Compared to VCAD, CCAD was significantly associated with older age (54 [44-66] vs. 49 [37-62]), Black race (12.6% vs. 8.7%), atrial fibrillation (6.1% vs. 3.7%), hypertension (58.0% vs. 53.9%), fewer concurrent acute ischemic strokes (AIS) (22.1% vs. 24.7%), higher NIHSS (mean NIHSS 7 [2-16] vs. 2 [0-5]), extended stays (4 days [2-8] vs. 4 days [2-7]) and increased hospitalization charges ($52,005 [$25,759-$118,806] vs. $43,199 [$24,116-$85,701]); all P<0.05. Within the concurrent AIS group, the CCAD group also exhibited an increased likelihood for IV thrombolysis (10.7% vs. 5.7%) and mechanical thrombectomy (14.9% vs. 3.7%). After propensity score matching for NIHSS and age, the CCAD group was associated with less death (adjusted odds ratio [aOR] 0.41, 95% CI 0.26-0.65, P<0.001) but a similar home discharge rate (aOR 1.15, 95% CI 0.78-1.69, P=0.480) (Figure). Conclusion: Our study underscores distinct comorbidity profiles and treatment patterns between CCAD and VCAD groups. These findings advocate for tailored treatment strategies based on dissection type to optimize patient outcomes.

Venous cystic adventitial disease (VCAD) is a rare vascular anomaly located in the common femoral vein in most cases. We describe the case of a 59-year-old female patient with right leg edema who was misdiagnosed with deep vein thrombosis of the lower extremity at another hospital. Magnetic resonance angiography revealed a round mass in the popliteal vein, with a narrow lumen. Considering the location of the lesion, absence of a history of deep venous thrombosis and trauma, and clinical manifestations, the diagnosis is likely a popliteal vein adventitial cyst. Segmental popliteal vein resection and reconstruction were performed using a cylindrical great saphenous vein graft. No joint connection was found during the operation, and the postoperative pathology confirmed VCAD.

BACKGROUND: The sweetness of highbush blueberries (Vaccinium corymbosum L.) is related to changes in sucrose and other primary sugar metabolites. OBJECTIVE: This study compared the fruit quality and sugar metabolism in the blueberry cultivars Brigitta and Elizabeth at three ripening stages and with a postharvest chitosan treatment to determine which factors are important in sugar metabolism in the two cultivars. METHODS: Blueberries were harvested at three ripening stages. Fully ripe fruit was treated with chitosan and kept at room temperature for 5 and 10 days. GC-MS was used to measure organic acids, individual sugars, and sugar derivatives. Gene expression was analysed using qPCR. RESULTS: Elizabeth fruit was less firm than Brigitta fruit, but contained more soluble solids. The sweeter taste of Elizabeth versus Brigitta was due to down-regulated VcINV, VcSPS, and VcADR transcription and increased sucrose concentration. Chitosan inhibited VcADR and VcINV transcription in Elizabeth, but activated these genes in Brigitta after 5 days of storage. CONCLUSIONS: Aldose reductase might be an essential enzyme in blueberry sugar metabolism. These findings support research on the mechanism of sugar accumulation in fruit during maturation and after postharvest treatments in blueberries.

ABSTRACT Invent of 3D and 4D ultrasound has made a dramatic improvement in fetal imaging. Various viewing directions and rendering modes help better demonstration of pathologies suspected on 2D US. Multiplanar mode is the key of the 3D US imaging. Software like magicut and TUI help to understand the anatomy better. Volume ultrasound is an excellent tool for diagnosis of facial defects, spinal abnormalities, limb abnormalities, etc. 4D US shows fetal movements and expressions that are basis for the neurodevelopment of the fetus. STIC and VCAD are the tools that have made detection of fetal cardiac anomalies more precise.

Abstract Introduction Genetic background is thought to be responsible for a family occurred premature atherosclerosis, including myocardial infarction (MI). Purpose The aim of the study was to investigate the role of genetic variants in young patients (aged <50 years) with MI and family history of premature atherosclerosis. Methods The studied group consisted of 70 patients aged 26-49 (mean 43.1, SD ±4.3), 17 women and 53 men, with MI and with family history of premature atherosclerosis, defined as MI or ischaemic stroke in first-degree relatives at age <65 years in women or <55 years in men. The mean BMI in the studied group was 28.8 kg/m2 (SD ±3.5), total cholesterol level 202.3 mg/dl (SD ±3.5), HDL 40.6 mg/dl (SD ±9.6), LDL 124.0 mg/dl (SD ±28.9), triglycerides 164.4 mg/dl (SD ±63.5), glucose 108.3 mg/dl (SD ±19.9) and creatinine 0.9 mg/dl (SD ±0.2). Regarding other risk factors 63 patients (90%) were smokers (mean 24.1 pack-years, SD ±13.0), 44 (62.8%) had hypertension, 11 (15.7%) had diabetes mellitus, and 8 (11.4%) had depression. All patients had diagnosed MI including MI with ST elevation (STEMI) in 18 cases (25.7%) and MI without ST elevation (NSTEMI) in 52 cases (74.3%). All patients, except 2 (no consent), had performed coronary angiography revealing 1-vessel coronary artery disease (VCAD) in 33 patients (47.1%), 2-VCAD in 17 patients (24.3%), and 3-VCAD in 20 patients (28.6%). The mean left ventricular ejection fraction (LVEF) was 51.8% (SD ±8.0). The total DNA has been extracted from whole peripheral blood samples. The targeted enrichment library was prepared and analyzed using New Generation Sequencing method on Hiseq4000, 2x150 cycles. Statistical analyses were performed using the R software package (www.r-project.org/). The results of sequencing were compared to data from the reference control population consisting of 597 healthy people (418 women, 179 men) aged 18-83 (mean 40.5, SD ± 12,4) as a whole and after matching with a studied group by age and gender in a proportion 1:3 (210 people, 51 women and 159 men, aged 18-77, mean 42.1, SD ±10.6) using Propensity Score Matching. Risks associated with detected variants were evaluated using Fisher’s exact test based on the allelic frequencies of variants in both groups. Results SYNE1 gene variant rs36215567 (NM_182961.4: c.20396+22A>G) has been detected in statistically significant higher incidence in the studied group in comparison to the control population (p=0.005) with OR=4,80 (95%CI 1,43-14,45) as well as when compared to the control population matched by age and gender (p=0.004) OR=9,31 (95%CI 1,64-95,41). There were no statistically significant differences in the incidence of familial hypercholesterolemia related gene variants: LDLR c.667G>A, PCSK9 c.658-36G>A, PCSK9 c.996+55C>A and APOB c.12382G>A between both cohorts. Conclusion A novel variant of SYNE1 gene is associated with myocardial infarction in young age patients with a family history of premature atherosclerosis.

Background— The hemodynamic and vascular effects of ventricular sourcing by a stent-based (VSTENT, Percardia) left ventricle-to-coronary artery bypass were studied in a patient subgroup of the European multicenter ADVANTAGE study (ADjunctive treatment with the VCAB/VSTENT myocardial implANT system in coronary Artery bypass Graft patiEnts). Methods and Results— Twelve patients who underwent VSTENT implantation in addition to coronary artery bypass surgery were studied up to 12 months after the procedure. The VSTENT was implanted distal to a hemodynamically relevant coronary artery stenosis. Coronary flow velocity was assessed at rest and during dobutamine stress. Intraoperative VSTENT implantation was successful in 11 of 12 patients. Early postoperative angiograms showed patent VSTENT in 8 of 11 patients, with predominantly systolic flow distal to the VSTENT. Coronary flow velocity reserve induced by dobutamine stress was 1.7±0.1 ( P =0.006). VSTENT patency at 2- to 6-month follow-up was present in 5 of 11 patients, with concomitant VSTENT stenosis in 4 of those 5. In all patients, coronary flow velocity increased 3- to 4-fold proximal to the VSTENT, which was associated with a moderate degree of arterial remodeling. Except for target vessel reintervention (n=5), no other major adverse events were observed in 11 of 12 patients. One patient died on the second postoperative day, though the cause was probably not related to the VSTENT implantation. Conclusions— VSTENT implantation seems to be safe in the mid-term follow-up and leads to a predominantly systolic coronary flow pattern in the vessel supplied by the VSTENT, with a flow reserve similar or close to that seen with conventional bypass. VSTENT patency rate, however, was unacceptably low at 3- to 6-month follow-up and needs to be improved.
