Why do These Match? Explaining the Behavior of Image Similarity Models
Explaining a deep learning model can help users understand its behavior and
allow researchers to discern its shortcomings. Recent work has primarily
focused on explaining models for tasks like image classification or visual
question answering. In this paper, we introduce Salient Attributes for Network
Explanation (SANE) to explain image similarity models, where a model's output
is a score measuring the similarity of two inputs rather than a classification
score. In this task, an explanation depends on both of the input images, so
standard methods do not apply. Our SANE explanations pairs a saliency map
identifying important image regions with an attribute that best explains the
match. We find that our explanations provide additional information not
typically captured by saliency maps alone, and can also improve performance on
the classic task of attribute recognition. Our approach's ability to generalize
is demonstrated on two datasets from diverse domains, Polyvore Outfits and
Animals with Attributes 2. Code available at:

Fatalism, Social Support and Mental Health in Four Former Soviet Cultures
Research on social support has identified differences in levels of support between cultures, but has provided only a limited explanation of the role of values or beliefs in accounting for such variations. In this paper we examine the relationship between fatalism and perceived support amongst 2672 respondents in four former Soviet States (Russia, Georgia, Ukraine and Belorussia), with participants drawn from groups of manual workers, managers, civil servants, students and the retired in these four countries. We also examine the consequences of such social support for mental health across these nations. Findings indicate a small but significant moderator effect for fatalism on the relationship between social support and mental health. These results are discussed in the context of the continuing economic and social challenges facing the citizens of these nations

Предикторы летального исхода у пациентов с сочетанием туберкулеза, с устойчивостью к рифампицину, и ВИЧ-инфекции
The objective: to identify and rank the predictors of lethal outcome in patients with tuberculosis resistance to at least rifampicin and concurrent HIV infection (TB-R/HIV).Subjects and methods. 130 cases TB-R/HIV notified in Rostov Region in 2017-2018 were included in an observational retrospective cohort study. Two cohorts were formed: cohort A consisted of 31 patients with a documented fatal outcome within 12 months after registration for treatment, cohort B included 99 patients didn't die at least during the first year after registration for treatment. At the first stage of the study, the statistical significance of differences of certain signs in patients of cohorts A and B was determined. The signs with confirmed statistical significance of differences were included in the second stage of the study, during which their sensitivity as predictors of lethal outcome was determined. For this, automated artificial neural networks were used.Results. The following can be used as predictors of lethal outcome for TB-R/HIV patients (in decreasing order of significance): homelessness (people who have no place of residence), addiction to alcohol or drugs, interruption of anti-TB chemotherapy in the past, low body mass index, low hemoglobin level, including anemia (but not severe), low level of CD4 T-lymphocytes (the prognosis is especially unfavorable with less than 100 cells/μl). The level of total protein may also be a potential predictor, however, the selection criteria for this indicator require further clarification.Цель исследования: выявить и ранжировать по значимости предикторы летального исхода у пациентов с туберкулезом, с устойчивостью как минимум к рифампицину, и ВИЧ-инфекцией (ТБ-Р/ВИЧ).Материалы и методы. В обсервационном ретроспективном когортном исследовании изучены сведения о 130 случаях ТБ-Р/ВИЧ, зарегистрированных в Ростовской области в 2017-2018 гг. Из них сформировано две когорты: когорта А ‒ 31 пациент с зарегистрированным наличием летального исхода в течение 12 мес. после регистрации для лечения, когорта Б ‒ 99 пациентов, у которых летальный исход не возник по крайней мере в течение первого года после регистрации для лечения. На первом этапе исследования определяли статистическую значимость различий тех или иных признаков у пациентов когорт А и Б. Признаки, для которых установлена статистическая значимость различий, были включены во второй этап исследования, на котором определяли их чувствительность как предикторов летального исхода. Для этого использовали метод автоматизированных искусственных нейронных сетей.Результаты. В качестве предикторов летального исхода у больных ТБ-Р/ВИЧ могут быть использованы (в порядке убывания значимости): отсутствие места жительства (лица без определенного места жительства), наличие зависимости от алкоголя или наркотиков, прерывание предшествующего курса противотуберкулезной химиотерапии в анамнезе, низкий индекс массы тела, низкая концентрация гемоглобина, включая наличие (но не выраженность) анемии, малое число СD4 Т-лимфоцитов (особенно неблагоприятный прогноз при числе менее 100 кл/мкл). Потенциальным предиктором может быть также уровень общего белка, однако критерии отбора данного признака нуждаются в уточнении

Effect of sodium salt of 3-(2-oxo-3-phenyl-2H-[1,2,4]triazine[2,3-c] quinazolin-6-yl) propanoic acid and bemityl on biochemical processes in rats organism in the conditions of the daily training with running in treadmill
Department of Pharmacology, N. I. Pirogov National Medical University of Vinnitsa, UkraineBackground: The limited arsenal of actoprotectors by almost one bemethyl has caused the necessity to search the substances with the above action,
suitable for the creation of a new drug on their basis.
Material and methods: For the investigation the substances of sodium salt of 3-(2-oxo-3-phenyl-2H-[1,2,4]triazine[2,3-c]quinazolin-6-yl) propane
acid with the laboratory ciphers MT-279 has been taken. The studies have been performed on 56 nonlinear male rats in the conditions of the 15-daily
physical loading which promoted the normalization of energy processes in skeletal muscles (energy resources were increased, lactoacidosis was removed,
the lipolysis was activated) and interaction within system «pro-and antioxidant».
Results: It has been established that the course (15 days) intraperitoneal injections in rats with sodium salt of 3-(2-oxo-3-phenyl-2H-[1,2,4]
triazine[2,3-c]quinazolin-6-yl) propane acid (MT-279, 2.5 mg/kg), as well as bemethyl (33 mg/kg) promoted the normalization of energy processes in skeletal
muscles (energy resources were increased, lactoacidosis was removed, the lipolysis was activated) and interaction within system «pro-and antioxidant».
Conclusions: The compound MT-279 has the largest actoprotective effect virtually mapped to bemethyl. A complex of effects inherent of MT-279
compound indicates the advisability of the in-depth study of its pharmacological properties to find out its safety and suitability for creating a new drug
on its basis
Anterior Abdominal Wall Pain
Aim: to present modern approaches to the differential diagnosis and treatment of anterior abdominal wall pain.Key points. Pain in the anterior abdominal wall is a common reason for visiting a gastroenterologist and is often misinterpreted. Signs that distinguish it from visceral and parietal pain include local character, a positive Carnett sign and the effectiveness of local anesthetic injection. Among the main causes, it is necessary to highlight diseases that are not accompanied by a palpable mass in the anterior abdominal wall (anterior cutaneous nerve entrapment syndrome, ilioinguinal nerve syndrome, slipping rib syndrome, radiculopathy and myofascial pain syndrome). Another group of causes of pain in the anterior abdominal wall is represented by diseases in which areas of infiltration (tumors, endometriosis, infections) or hernial protrusions are determined, in which radiation methods play an important role in diagnosis.Conclusion. Knowledge of pathognomonic clinical and instrumental signs is the basis for differential diagnosis and choice of treatment strategy for pathology of the anterior abdominal wall
