Authors: Contreras Valdez Mario 
Published: November 2023

In this article we deal with the output of small and medium-sized silver mines located throughout northwest Mexico’s great mountain range known as the Western Sierra Madre. We approach these diversely organized economic units, lying within a sundry political and commercial network, during a fifty years’ period. We stress the fact that its productive lifespan favored private profitability, and became a source of tax revenues, and economic dynamism in that Mexican region between 1822 and 1872. This early mining activity influenced the entire economy by means of the operation of the Guadalajara, Culiacan, Hermosillo and Alamos mints, as well as with the exportation of silver from the ports of San Blas, Mazatlán and Guaymas.
En este artículo se aborda la continua producción de plata de las pequeñas y medianas minas localizadas dispersas por la cordillera del noroeste de México, el macizo montañoso que se conoce como Sierra Madre Occidental. Proponemos una aproximación de esas unidades económicas, con diferente organización productiva y con desiguales redes comerciales y políticas, durante ese medio siglo. Se insiste en que esa vigencia productiva provocó rentabilidad privada, generó recursos a la hacienda pública, e imprimió dinamismo económico en esta región de México durante los años de 1822 a 1872. Esta actividad minera inicial se extendía en la economía con el acompañamiento de la operación de las casas de moneda de Guadalajara, Culiacán y las de Hermosillo y Álamos, y también con la exportación argentífera desde los puertos de San Blas, Mazatlán y Guaymas.

Kabupaten Bantaeng memiliki potensi untuk perkembangan perikanan dan hasil rumput laut yang besar. Potensi tersebut didukung oleh garis pantai yang memanjang pada bagian barat dan timur sepanjang 21,5 kilometer yang cukup potensial untuk perkembangan perikanan dan rumput laut. Hasil panen dan pengolahan pasca panen yaitu proses pengeringan sangat mempengaruhi kuantitas dan mutu dari rumput laut. Kondisi cuaca terutama saat musim hujan menjadi salah satu kendala bagi para petani rumput laut saat melakukan pengolahan pasca panen terutama pada proses pengeringan lebih menjadi lama. Karena proses pengeringan memanfaatkan sinar matahati langsung sebagai sumber Panas. Masalah tersebut dapat teratasi dengan pemakaian alat pengering yang memanfaatkan sumber panas selain dari matahari yang dapat berupa hasil pembakaran gas, biomassa atau pemakaian komponen pemanas listrik. Penelitian ini menyajikan sebuah alat pengering yang mampu menghasilkan panas tanpa adanya sinar matahari.

New robust state‐estimation frameworks for angles‐only underwater target tracking problems
Authors: Urooj Asfia , Radhakrishnan Rahul 
Published: November 2023

SummaryTracking a moving target using only angle measurements is a challenging and complex problem. This is because the measurements received from a sensor on a moving observer provide very little information about the target's movements. Additionally, there are uncertainties regarding the target's initial range and speed, which can further complicate the estimation process. The angle measurements themselves carry a lot of uncertainties as they can be affected by significant outliers, which do not fit the standard Gaussian distribution that estimation algorithms typically assume. Furthermore, the observer's position can also be uncertain due to various environmental factors. To address these challenges and to propose a robust, unified and accurate solution, two new estimation frameworks are proposed. They involve making use of a range and speed parametrization approach to compensate for the initial uncertainty in the target's range and speed. They also involve using a maximum correntropy (MC) criterion and a numerically stable centered error entropy (CEE) criterion to deal with measurement outliers and the observer motion uncertainties. The performance of the proposed frameworks is evaluated by comparing them to the traditional unscented Kalman filter (UKF) and its parametrized versions using different performance metrics. The simulations conducted showed that the developed algorithms perform better in terms of estimation accuracy than conventional methods. Specifically, the second framework based on the CEE criterion outperformed MC‐based estimators.

AbstractMyeloid‐derived suppressor cell (MDSC)‐like adherent cells (MLACs) are a recently identified CD11b+F4/80− myeloid cell subset that can infiltrate tumors early in development and promote their growth. Because of these functions, MLACs play an important role in establishing an immunosuppressive tumor microenvironment (TME). However, the lack of MLAC‐specific markers has hampered further characterization of this cell type. This study identifies the gene signature of MLACs by analyzing RNA‐sequencing (RNA‐seq) and public single‐cell RNA‐seq data, revealing that MLACs are an independent cell population that are distinct from other intratumoral myeloid cells. After combining proteome analysis of membrane proteins with RNA‐seq data, H2‐Ab1 and CD11c are indicated as marker proteins that can support the isolation of MLAC subsets from CD11b+F4/80− myeloid cells by fluorescence‐activated cell sorting. The CD11b+F4/80−H2‐Ab1+ and CD11b+F4/80−CD11c+ MLAC subsets represent approximately half of the MLAC population that is isolated based on their adhesion properties and possess gene signatures and functional properties similar to those of the MLAC population. Additionally, membrane proteome analysis suggests that MLACs express highly heterogeneous surface proteins. This study facilitates an integrated understanding of heterogeneous intratumoral myeloid cells, as well as the molecular and cellular details of the development of an immunosuppressive TME.
