Domain-Adaptive Self-Supervised Pre-Training for Face & Body Detection in Drawings

Drawings are powerful means of pictorial abstraction and communication. Understanding diverse forms of drawings, including digital arts, cartoons, and comics, has been a major problem of interest for the computer vision and computer graphics communities. Although there are large amounts of digitized drawings from comic books and cartoons, they contain vast stylistic variations, which necessitate expensive manual labeling for training domain-specific recognizers. In this work, we show how self-supervised learning, based on a teacher-student network with a modified student network update design, can be used to build face and body detectors. Our setup allows exploiting large amounts of unlabeled data from the target domain when labels are provided for only a small subset of it. We further demonstrate that style transfer can be incorporated into our learning pipeline to bootstrap detectors using a vast amount of out-of-domain labeled images from natural images (i.e., images from the real world). Our combined architecture yields detectors with state-of-the-art (SOTA) and near-SOTA performance using minimal annotation effort.Comment: Preprint, 8 pages of the paper itself + 7 pages of Supplementary Material.

Electromechanical delay detected by tissue Doppler echocardiography is associated with the frequency of attacks in patients with lone atrial fibrillation

Background: Our main purpose in this study is to compare atrial (inter-atrial, intra-leftatrial, intra-right atrial) electromechanical delays of patients with lone atrial fibrillation (LAF) with healthy individuals and examine the relationship of annual LAF attack frequency.Methods: 32 entirely healthy individuals and 32 patients who have presented with tachycardia and complying with LAF criteria have been included in the study. The time passing from the beginning of the P wave on electrocardiography to the A’ wave on tissue Doppler trace was accepted as the atrial conduction time (PA’). The PA’ time difference between the mitral annulus of left ventricle (ML) and the tricuspid annulus of right ventricle (TL) was defined as inter-atrial electromechanical delay (IA-EMD), the PA’ time difference between the ML and septal mitral annulus (MS) as intra-left electromechanical delay (ILeft-EMD), the PA’ time difference between MS and the TL as intra-right electromechanical delay (IRight-EMD).Results: ILeft-EMD (21.8 ± 9.1 vs. 14.1 ± 4.9, p < 0.001), IRight-EMD (9.3 ± 6.8 vs. 5.9 ± 4.9, p = 0.03) and IA-EMD times (24.7 ± 11.2 vs. 11.9 ± 7.1, p < 0.001) were significantly longer in LAF patients. In multivariate regression analysis, using a model including age, gender and left atrium (LA) volumes, ILeft-EMD times (OR 1.14, 95% CI 1.03–1.27,p = 0.012), IA-EMD times (OR 1.12, 95% CI 1.03–1.23, p = 0.007) and LA volumes (OR 1.18, 95% CI 1.05–1.32, p = 0.005) were independent predictors of LAF. In LAF group, the frequency of AF episodes was significantly correlated with ILeft-EMD (r = 0.90, p < 0.001) and IA-EMD times (r = 0.36, p < 0.004), whereas, IRight-EMD times and LA volumes were not correlated with recurrence rates.Conclusions: ILeft-EMD and IA-EMD may increase in the early stages of atrial fibrillation even without the left atrial dilation and may be more valuable than left atrial area and volume in predicting atrial fibrillation

Multiparametric MRI guidance in first-time prostate biopsies: what is the real benefit?

PURPOSEWith the increased recognition of the capabilities of prostate multiparametric (mp) magnetic resonance imaging (MRI), attempts are being made to incorporate MRI into routine prostate biopsies. In this study, we aimed to analyze the diagnostic yield via cognitive fusion, transrectal ultrasound (TRUS)-guided, and in-bore MRI-guided biopsies in biopsy-naive patients with positive findings for prostate cancer screening.METHODSCharts of 140 patients, who underwent transrectal prostate biopsy after the adaptation of mp-MRI into our routine clinical practice, were reviewed retrospectively. Patients with previous negative biopsies (n=24) and digital rectal examination findings suspicious for ≥cT3 prostate cancer (n=16) were excluded. T2-weighted imaging, diffusion-weighted imaging, and dynamic contrast-enhanced imaging were included in mp-MRI. Cognitive fusion biopsies were performed after a review of mp-MRI data, whereas TRUS-guided biopsies were performed blinded to MRI information. In-bore biopsies were conducted by means of real-time targeting under MRI guidance. RESULTSBetween January 2012 and February 2014, a total of 100 patients fulfilling the inclusion criteria underwent TRUS-guided (n=37), cognitive fusion (n=49), and in-bore (n=14) biopsies. Mean age, serum prostate specific antigen level, and prostate size did not differ significantly among the study groups. In TRUS-guided biopsy group, 51.3% were diagnosed with prostate cancer, while the same ratio was 55.1% and 71.4% in cognitive fusion and in-bore biopsy groups, respectively (P = 0.429). Clinically significant prostate cancer detection rate was 69.1%, 70.3%, and 90% in TRUS-guided, cognitive fusion, and in-bore biopsy groups, respectively (P = 0.31). According to histopathologic variables in the prostatectomy specimen, significant prostate cancer was detected in 85.7%, 93.3%, and 100% of patients in TRUS-guided, cognitive fusion, and in-bore biopsy groups, respectively. CONCLUSIONIn the first set of transrectal prostate biopsies, mp-MRI guidance did not increase the diagnostic yield significantly

Current barriers and recommendations on the diagnosis of transthyretin amyloid cardiomyopathy: a Delphi study

ObjectivesThis study has been conducted to investigate the non-invasive diagnostic journey of patients with a transthyretin amyloid cardiomyopathy (aTTR-CM) in Turkey, identify the challenges and uncertainties encountered on the path to diagnosis from the perspectives of expert physicians, and develop recommendations that can be applied in such cases.MethodsThis study employed a three-round modified Delphi method and included 10 cardiologists and five nuclear medicine specialists. Two hematologists also shared their expert opinions on the survey results related to hematological tests during a final face-to-face discussion. A consensus was reached when 80% or more of the panel members marked the “agree/strongly agree” or “disagree/strongly disagree” option.ResultsThe panelists unanimously agreed that the aTTR-CM diagnosis could be established through scintigraphy (using either 99mTc-PYP, 99mTc-DPD, or 99mTc-HMPD) in a patient with suspected cardiac amyloidosis (CA) without a further investigation if AL amyloidosis is ruled out (by sFLC, SPIE and UPIE). In addition, scintigraphy imaging performed by SPECT or SPECT-CT should reveal a myocardial uptake of Grade ≥2 with a heart-to-contralateral (H/CL) ratio of ≥1.5. The cardiology panelists recommended using cardiovascular magnetic resonance (CMR) and a detailed echocardiographic scoring as a last resort before considering an endomyocardial biopsy in patients with suspected CA whose scintigraphy results were discordant/inconclusive or negative but still carried a high clinical suspicion of aTTR-CM.ConclusionThe diagnostic approach for aTTR-CM should be customized based on the availability of diagnostic tools/methods in each expert clinic to achieve a timely and definitive diagnosis

Economical and commercial struggles of major forces in the Bagdad province end its environs,according to Russian consul reports (1907-1909 )

Bağdat ve havalisi, Avrupa ile Asya'yı birbirine bağlayan, Akdeniz ile Basra Körfezi'ne ulaşımı sağlayan tarihi ticaret yolu üzerinde yer almıştır. Bölgenin jeopolitik önemi ve zenginliği nedeniyle tarih boyunca büyük güçlerin hep ilgisini çekmiştir. İngiltere XIX. Yüzyılda egemenliği altındaki Hindistan'ın güvenliğini sağlamak ve Bağdat ve havalisindeki gücünü arttırmak için bu bölgeye dair faaliyetlerini arttırmıştır. Süveyş Kanalı'nm açılması ve denetiminin İngiltere'ye geçmesi ile Bağdat ve havalisi ile dünyanın çeşitli bölgeleri arasında yapılan ticaretin ağırlık merkezi Akdeniz'den Basra Körfezine kaymıştır. Bu dönemden sonra Bağdat ve havalisindeki ticarette, İngiltere öne çıkmaya başlarken, Rusya ve Almanya başta olmak üzere Avrupalı büyük devletler, bu bölgede etkisini arttırmaya çalışmıştır. Osmanlı Devleti, kendi sınırları dâhilinde yer alan söz konusu bölge ile ticari ilişkilerini geliştirmek bakımından Avrupalı büyük güçlere oranla geri kalmıştır.Bagdad province is located on the historical commercial route which was a link between Asia and Europe, providing transportation between the Mediterranean and the Persian Gulf. The major powers always concerned with the region throughout the history because of its geopolitical importance and richness. The United Kingdom increased its operations in the XIX. century to both enhance the power in the Bagdad province and its environs, and to ensure the security of India which is dominated by UK. By the commencement of „the Suez Canal which was controlled by the UK, the commerce between Bagdad and the other parts of the world was concentrated at the Persian Gulf. By this time, UK came forward for the commercial activities in Bagdad and its environs and the major European states, especially Russia and Germany, tried to increase their influence in the region. The Ottoman Empire lagged in the mentioned region which was in its own borders, relative to major European forces

The activities of Armenians and Nestorians in Urmia region

Ekim 1917 Bolşevik İhtilali sonrasında Rusya savaş dışı kalmıştır. Bu durum Birinci Dünya Savaşı’nda Rusya, İngiltere, Osmanlı Devleti ve Almanya arasında fiili savaş da dâhil türlü mücadelelere sahne olan İran topraklarında Türk ve Alman güçleri için avantaj sağlamıştır. Söz konusu süreçte Türk kuvvetleri, İran içlerinden Kafkaslara yönelmeye başlarken, İngiltere de İran’da Rusya’nın boşalttığı bölgeleri ele geçirmeye çalışmıştır. İngiltere, Türk kuvvetlerinden önce İran’ın kuzeyini işgal etmek istemesine rağmen bu iş için askeri gücünün yetersiz olması nedeniyle Urmiye ve havalisinde toplanmaya başlayan Ermeni ve Nasturilere destek vermiştir. Ermeni ve Nasturiler de bu bölgelerdeki Türk kuvvelerine ve sivil Müslüman ahaliye saldırmışlar ve pek çoğunu katletmişlerdir.After Bolshevik Mutiny in October,1917 Russia became hors de combat. The situation provided advantage for Turkish and German troops in Iran land witnessed various struggles including active war among Russia, England, the Ottoman Empire and Germany in the 1st World War. During the period, Turkish troops started to go towards Caucasia through Iran while tried to take over the areas that Russia evacuated in Iran. Though England wanted to occupy North of Iran before Turkish troops, it supported Armenians and Nestorians, began to gather Urmiye and its neighbourhood. Armenians and Nestorians attacked Turkish troops and civil Muslims in these areas and slaughtered many of them

Afyonkarahisar’da Millet Mekteplerinin Açılışı ve Afyonkarahisar Basınına Yansımaları

Harf inkılâbının gerçekleşmesinin ardından ilk aşamada yeni Türk harflerini en kısa zamanda, mümkün mertebe en fazla vatandaşa öğretebilmek gayesiyle Millet Mektepleri açılmıştır. Millet mektepleri; açılış tarihi olan 1 Ocak 1929 tarihinde Türkiye Cumhuriyeti’nin pek çok bölgesinde, yaklaşık üç ay gibi kısa bir zaman içinde teşkilatlanmasını tamamlayarak eğitim öğretim faaliyetlerine başlamıştır. Millet mekteplerine Türk halkının ilgi ve alakasını arttırabilmek için milli ve yerel basında söz konusu mekteplerin gerek teşkilatlanmaları, gerek eğitim ve öğretim çalışmaları ve gerekse mali konularda teferruatlı malumatlara yer verilmiştir. Afyonkarahisar da bu görevi şehrin o dönemdeki en önemli basın organı olan Son Haber gazetesi üstlenmiştir.After the administration of the Alphabet Revolution, first of all Millet Mekteps (National Schools) were opened in order to teach these new Turkish letters to as many citizens as possible. Opened on January 1, 1929, the Millet Mekteps was become widespread in the country and started education in three months. To make known of National Schools and increase Turkish public interest to these schools, news was seen about their organization, education system, and financial matters in local press. In Afyonkarahisar the Son Haber, which was the most influential newspaper of that time, took the responsibility to fulfill this duty
