Mazkur maqolada O'zbekistonda kimyo sanoatini rivojlantirishning institutsional, xomashyo, texnologik, investitsion, eksport, ekologik va hududiy xususiyatlari tizimli ravishda tadqiq etildi. Tadqiqotda 2024–2025-yillarga oid rasmiy statistik ma'lumotlar, "O'zkimyosanoat" AJ hisoboti, O'zbekistonning kimyo va gaz-kimyo sanoatini strategik rivojlantirish dasturi hamda xalqaro ilmiy adabiyotlar tahlil qilindi. Natijalar kimyo mahsulotlari ishlab chiqarish hajmining uzoq muddatda sezilarli oshganini, investitsiya faolligi kuchayganini, biroq tarmoqda energiya sig'imdorligi, eskirgan uskunalar, importga bog'liqlik, yuqori qo'shilgan qiymatli mahsulotlar ulushini oshirish va ekologik samaradorlik masalalari saqlanib qolayotganini ko'rsatdi. Tadqiqot natijalari kimyo sanoatida resurs samaradorligi, mahsulot diversifikatsiyasi, ilmiy-tadqiqot va tajriba-konstruktorlik ishlari, klasterlash, kadrlar tayyorlash va eksport geografiyasini kengaytirish bo'yicha ilmiy-amaliy tavsiyalarni shakllantirish imkonini beradi.

This release contains 18 trained PyTorch checkpoints for six lane-marking detection methods evaluated in the OrthoLaneMark benchmark: U-Net, SCNN, UFLDv2, PolyLaneNet, LaneATT, and CLRNet. Three checkpoints are provided for each method, corresponding to random seeds 0, 1, and 2. The models use pavement intensity images and the fixed OrthoLaneMark split of 835 training, 192 validation, and 294 test images. Checkpoints were selected using validation gated region accuracy (GRA). Configurations and a manifest containing selected epochs, final presence thresholds, and file hashes are included. These checkpoints support reproduction of the learning-method results in “Presence-Aware Benchmarking of Lane-Marking Detection Methods for Pavement Distress Measurement,” under review at the ASCE Journal of Computing in Civil Engineering. Benchmark code and saved results are provided in the linked GitHub repository; the dataset is distributed separately. CC BY 4.0 applies to the benchmark authors’ contributions. Pretrained components retain their applicable third-party terms. Contacts: Haolin Wang, hlwang98@gatech.edu; Zhongyu Yang (corresponding author), zyang398@gatech.edu.

Ushbu maqolada O'zbekiston Respublikasining eksport salohiyatini oshirish masalalari nazariy va amaliy jihatdan tahlil qilingan. Maqolada 2023–2025-yillar davomidagi eksport hajmi dinamikasi, uning tovar va xizmatlar bo'yicha tarkibiy tuzilishi hamda asosiy tendensiyalari statistik ma'lumotlar asosida o'rganilgan. A. Smitning absolyut ustunlik nazariyasidan tortib, D. Rikardoning qiyosiy ustunlik konsepsiyasi, Xekesher-Olin modeli hamda M. Porterning millatlarning raqobatbardosh ustunligi nazariyasigacha bo'lgan yondashuvlar umumlashtirilgan. Shuningdek, xorijiy va mahalliy olimlarning eksport salohiyati va raqobatbardoshlikka oid tadqiqotlari qiyosiy tahlil qilingan. O'zbekiston Respublikasi Milliy statistika qo'mitasi va Markaziy bankning rasmiy ma'lumotlari asosida 2023–2025-yillar davomidagi eksport hajmi dinamikasi, uning tovar guruhlari va xizmatlar turlari bo'yicha tarkibiy tuzilishi, shuningdek, asosiy tendensiyalari uch jadval va diagramma orqali vizuallashtirilgan holda o'rganilgan. Mamlakat eksportida qimmatbaho metallar (oltin) hissasi sezilarli o'rin tutib, bu holat eksport tarkibini yanada diversifikatsiya qilish va yangi istiqbolli yo'nalishlarni rivojlantirish uchun muhim imkoniyatlarni shakllantiradi. Maqola yakunida eksport salohiyatini yanada oshirish, xizmatlar va sanoat mahsulotlari ulushini kengaytirish bo'yicha aniq takliflar ishlab chiqilgan.

Introducción: La hiperplasia neuroendocrina pulmonar difusa idiopática (DIPNECH) es una enfermedad infrecuente reconocida como una lesión precursora de los tumores neuroendocrinos pulmonares. Su presentación con múltiples carcinoides pulmonares sincrónicos es excepcional. El propósito del presente reporte es describir las características radiológicas e histopatológicas que permitieron el diagnóstico de DIPNECH en una paciente asintomática. Caso Clínico: Mujer de 70 años, no fumadora, con antecedentes cardiovasculares e hipotiroidismo, en quien se detectó incidentalmente un nódulo pulmonar sólido de 13 mm en el lóbulo inferior izquierdo. La tomografía por emisión de positrones mostró leve captación metabólica y el seguimiento evidenció crecimiento progresivo. Se realizó lobectomía inferior izquierda por videotoracoscopia con linfadenectomía mediastínica. El estudio anatomopatológico identificó 23 tumores neuroendocrinos pulmonares sincrónicos, correspondientes a carcinoides típicos grado 1, de 2 a 11 mm, con índice proliferativo Ki-67 de 2%, sin compromiso ganglionar. La correlación radiológico-patológica permitió establecer el diagnóstico de DIPNECH asociado a múltiples carcinoides típicos pulmonares sincrónicos. Discusión: La DIPNECH es una entidad infrecuente y subdiagnosticada. Aunque su asociación con tumores carcinoides pulmonares está bien documentada, la presencia de veintitrés carcinoides típicos sincrónicos en una paciente asintomática es una presentación excepcional. Este caso destaca la relevancia de reconocer los hallazgos radiológicos sugestivos de DIPNECH, particularmente la coexistencia de múltiples micromódulos pulmonares y el patrón de perfusión en mosaico, los cuales pueden preceder al diagnóstico histopatológico definitivo. Su identificación temprana gracias al reconocimiento de sus hallazgos imagenológicos como en el presente caso puede llevar al diagnóstico y contribuir a un manejo temprano.
